accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the

significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or

warranty by us or any other person that we will achieve our objectives and plans in any specified time frame or at all. Moreover,

forward-looking statements speak only as of the date they are made. Other than required by law, we do not undertake any

Important factors that could cause actual financial, business, research, or operating results to differ materially from expectations

are disclosed in this annual report, including without limitation the following risk factors. Investors should carefully consider all the

information set forth in the following risk factors and elsewhere in this document before deciding to invest in any of the

Company’s securities. In addition to the risks listed below, we may be subject to other material risks that as of the date of this

report are not currently known to us or that we deem immaterial at this time.

Risks relating to legal and regulatory matters

Product liability claims could adversely affect our business, results of operations and financial condition

Product liability is a significant risk for any pharmaceutical company, given that liability claims relating to our industry are

unforeseeable by nature. The evolving regulatory environment worldwide (the ever-more stringent regulatory requirements

applicable to the pharmaceutical industry, plus more stringent data, quality, and supply obligations) clearly impacts our potential

liability, and we may incur different liability claims to what we have handled in the past, in terms of their nature, scope, and level.

For a description of the regulatory environment in which we operate, refer to “Item 4. Information on the Company - B. Business

Overview - B.5.3. Regulatory framework.” Substantial damages have been awarded by some jurisdictions and/or settlements

agreed – notably in the United States and other common law jurisdictions – against pharmaceutical companies based on claims

for injuries allegedly caused using their products. Such claims can also lead to product recalls, withdrawals, or declining sales,

and/or be accompanied by consumer fraud claims by customers, third-party payers seeking reimbursement of the cost of the

product and/or other claims, including potential civil or criminal governmental actions.

We are currently defending several product liability claims (see Note D.22.a. to our consolidated fi nancial statements included at

Item 18. of this annual report) notably with respect to Taxotere, Zantac, Talc products, and Depakine, and there can be no

assurance that we will be successful in defending these claims, or that we will not face additional claims in the future.

Establishing the full side effect profile of a pharmaceutical drug goes beyond data derived from preapproval clinical studies

which may only involve several hundred to several thousand patients. Routine review and analysis of the continually growing

body of post-marketing safety data and clinical studies provide additional information – for example, potential evidence of rare,

population-specific, or long-term adverse events or of drug interactions that were not observed in preapproval clinical studies.

This causes labeling to evolve over time following interactions with regulatory authorities, which may include restrictions of

therapeutic indications, new contraindications, warnings, or precautions and occasionally even the suspension or withdrawal of a

marketing authorization. Following any of these events, pharmaceutical companies can face significant product liability claims.

Furthermore, we commercialize several devices (some of which use new technologies) which, if they malfunction, could cause

unexpected damage and lead to product liability claims (see also “ — Breaches of data security, disruptions of information

technology systems and cyber threats could result in financial, legal, competitive, operational, business, or reputational harm ”

below).

2 SANOFI FORM 20-F 2025

PART I
ITEM 3. Key Information

Although we continue to insure a portion of our product liability with third-party carriers, product liability coverage is increasingly

difficult and costly to obtain, particularly in the United States . In the future, it is possible that self-insurance may become the sole

commercially reasonable means available for managing the financial risk associated with product liability in our pharmaceuticals

and vaccines businesses (see “Item 4. — B.8. Insurance and risk coverage”). In cases where we self-insure, the legal costs that we

would bear for handling such claims, and potential damage awards to be paid to claimants, could have a negative impact on our

financial condition. Due to insurance conditions, even when we have insurance coverage, recoveries from insurers may not be

totally successful due to market-driven insurance limitations and exclusions. Moreover, insolvency of an insurer could affect our

ability to recover claims on policies for which we have already paid a premium.

Product liability claims, regardless of their merits or the ultimate success of our defense, are costly, divert management’s

attention, may harm our reputation, and can impact the demand for our medicines or vaccines and generate speculative news

flows and/or rumors relating to such claims. Substantial product liability claims could materially adversely affect our business,

results of operations and financial condition, and/or may have an impact on market perception of our company and negatively

affect our stock price.

Claims and investigations relating to ethics and business integrity, competition law, marketing practices,

pricing, human rights of workers and other legal matters could adversely affect our business,

results of operations and financial condition

Our industry is heavily regulated and legal requirements vary from country to country, and new requirements are imposed on our

industry from time to time. Governments and regulatory authorities around the world have been strengthening implementation

and enforcement activities in recent years, including in relation to anti-bribery, anti-corruption, and ethical requirements with

respect to medical and scientific research, interactions with healthcare professionals and payers, and respect for the human

rights of workers.

We have adopted a Code of Conduct that requires employees to comply with applicable laws and regulations, as well as the

specific principles and rules of conduct set forth in the Code. We also have policies and procedures designed to help ensure that

we, our officers, employees, agents, intermediaries and other third parties comply with applicable laws and regulations (including

but not limited to the US Foreign Corrupt Practices Act (FCPA), the UK Bribery Act, the OECD Anti-Bribery Convention, the

French Anti-Corruption measures law (Sapin II), the French duty of vigilance law and other anti-bribery laws and regulations).

Notwithstanding these efforts, failure to comply with laws and regulations (including because of a business partner’s breach) may

occur and could result in liabilities for us and/or our management.

Sanofi and certain of its subsidiaries could become the subject of investigations or proceedings by various government entities or

could face audits and/or litigation, including allegations of corruption, claims related to employment matters, patent and

intellectual property disputes, consumer law claims and/or competition law and tax audits. We are currently the target of several

lawsuits relating to pricing and marketing practices (including, for example, “whistleblower” and 340B drug pricing program

litigation in the United States ), which we are vigorously defending. With respect to tax issues, the complexity of the fiscal

environment is such that the ultimate resolution of any tax matter may result in payments that are greater or less than the

provisions we have booked. See “Item 8. Financial Information — A. Information on Legal or Arbitration Proceedings” and

Note D.22. to our consolidated financial statements included at Item 18. of this annual report. In addition, responding to such

investigations is costly and may divert management’s attention from our business.

Unfavorable outcomes in any of these matters, or in similar matters that may arise in the future, could preclude the

commercialization of our medicines and vaccines, harm our reputation, negatively affect the profitability of existing medicines

and vaccines and subject us to substantial fines, punitive damages, penalties and injunctive or administrative remedies, possible

reputational harm, potential imposition of additional regulatory controls, monitoring or self-reporting obligations, or exclusion

from government reimbursement programs or markets, all of which could have a material adverse effect on our business, results

of operations or financial condition.

The unpredictability of these proceedings could lead Sanofi, after consideration of all relevant factors, to enter into settlement

agreements to settle certain claims. Such settlements may involve significant monetary payments and/or potential criminal

penalties, may include admissions of wrongdoing and may require entering into a Corporate Integrity Agreement (CIA), a

Deferred Prosecution Agreement or similar agreement (in the United States or elsewhere), agreements intended to regulate

company behavior for a specified number of years.

Our business activities are subject to extensive and significant government legislation and regulations,

compliance with which is often costly. Our business, results of operations and/or financial condition

could be adversely affected if we fail to comply with them, obtain and maintain the requir ed approvals,

anticipate legal changes or developments and/or adapt to changes in applicable law

All aspects of our business, including research and development, manufacturing, marketing, reimbursement, pricing, and sales,

are subject to extensive legislation and governmental regulation (see also "— Research, clinical development and regulatory

approval processes present significant risks to our pipeline success and portfolio renewal " below).

Compliance with applicable legislation and regulations has been and may be costly, and such costs may increase in future. For

example, post marketing regulatory requirements have increased the costs associated with maintaining marketing authorizations.

To monitor our compliance with applicable law, the FDA, EMA, WHO and comparable national agencies in other jurisdictions

routinely conduct regulatory inspections of our facilities, distribution centers, commercial activities, and development centers

(including hospitals), the number of which will increase in the context of new product launches, and such agencies may identify

potential deficiencies that we must adequately address. More generally, if we fail to adequately respond to regulatory inspection

observations identified during an inspection or fail to comply with applicable regulatory requirements (including within the

SANOFI FORM 20-F 2025 3

PART I
ITEM 3. Key Information

targeted timeline), we could be subject to enforcement, remedial and/or other actions by the FDA (such as warning letter,

injunction, seizure or cease and desist order), the EMA or other regulatory authorities, and we may also ultimately face potential

supply continuity consequences. For example, in January 2025 the FDA issued an inspection-related warning letter related to

certain GMP practices at our Framingham facility.

The evolving regulatory environment presents significant operational challenges across multiple jurisdictions. In the European

Union (EU) the increasing fragmentation of national law due to potentially inconsistent transposition of EU directives into EU

member state national law may result in complex compliance burdens, delayed market access, and heightened operational costs

across the environmental, data protection, and pharmaceutical domains, which would make operating in Europe more costly and

slower than in other regions. Concurrently, the dynamic changes in the US regulatory and policy landscape coupled with

institutional changes, including shifts in US vaccine policy, at regulatory agencies under the Department of Health and Human

Services (such as the Centers for Disease Control and Prevention and FDA) may lead to uncertainties with changing expectations

from the authorities, including revisiting certain previous decisions approving medicines or vaccines. Significant changes in

expectations, regulations and regulatory guidance could adversely impact our timelines for product approvals, regulatory

processes and potentially our ability to bring critical medicines or vaccines to patients in a timely manner.

For example, the pharmaceutical industry has experienced challenges due to the implementation of the new European Union

regulations for Medical Devices (EU MDR) and for In-Vitro Diagnostic Devices (IVDR), which entered into force in May 2021 and

May 2022, respectively. In October 2024, the European Parliament adopted a resolution for a revision of these regulations with a

view to addressing challenges, in particular obstacles associated with the implementation of the EU MDR and IVDR; however, the

outcome of that resolution is uncertain at this stage.

More broadly, government disruptions (including shutdowns, furloughed workers, reduced or frozen federal funding, the

medium- and long-term impacts thereof, or the de-prioritization of essential regulatory functions such as marketing application

reviews, facility inspections, safety monitoring, and routine health authority support) pose substantial risks to availability of

governmental authorities and approval schedules, ultimately threatening timely patient access to essential medicines and

vaccines across affected markets, which could have a material adverse effect on our business, results of operations or financial

condition.

In addition, we have an obligation to monitor and report adverse events and safety signals. To comply with these duties, we must

regularly train our employees and certain third parties (such as external sales forces and distributor employees) on regulatory

matters, including on pharmacovigilance. If we fail to train these people, or fail to train them appropriately, or if they do not

comply with regulatory and contractual requirements, we may be exposed to the risk that safety events are not reported, or not

reported in a timely manner, in breach of our reporting obligations.

For information about risks related to changes (i) in proprietary rights rules and regulations, see “— We rely on our patents and

other proprietary rights to provide exclusive rights to market certain of our medicines and vaccines. If such patents and other

rights were limited, invalidated, or circumvented, our financial results could be adversely affected ” below; and (ii) in

environmental rules and regulations, see “— Management of the historical contamination related to our past industrial activities

could adversely impact our results of operations and reputation ” below.

In addition, changes in applicable laws and the costs of compliance with such laws and regulations could have an adverse effect

on our business, results of operations and/or financial condition.

Changes in tax laws or regulations or their interpretation or exposures to additional tax liabilities around the world could

negatively impact our operating results. Changes to tax laws or regulations may occur at any time, and any related expense or

benefit recorded may be material to the fiscal quarter and year in which the law change is enacted or becomes effective. As a

result of the 2024 presidential and legislative elections in the United States , changes to applicable laws and regulations that have

been announced, proposed, and/or adopted, or could be made or expanded in the future, may result in new or expanded trade

restrictions by the United States and/or other countries, including, but not limited to, tariffs or import taxes being applied to

imported goods and services which could affect our operations and our exports into the United States . For example, the One Big

Beautiful Bill Act was signed into law on July 4, 2025 and made significant changes to US federal income tax laws, including,

among other things, the reintroduction of immediate expensing of domestic research and development expenditures, the

restoration of 100% bonus depreciation and changes to the limitation on business interest expense deductions. Other countries

may implement trade restrictions and/or retaliatory measures as well. Any such trade restrictions or measures could affect our

operations, our exports into the United States and other countries and/or our supply chains. Further significant modifications to

tax legislation are also expected in some of the markets where we operate, such as France and the United States . All these

elements could negatively impact our business, results or operations and/or financial condition.

Furthermore, most of the jurisdictions in which we operate have double tax treaties with other foreign jurisdictions, which provide

a framework for mitigating the impact of double taxation on our revenues and capital gains. However, the outcome of those

mechanisms developed to resolve such conflicting claims can in some circumstances be uncertain and can be expected to be

very lengthy. Provisions for tax contingencies are made based on experience, interpretations of tax law, and judgments about

potential actions by tax authorities. However, due to the complexity of tax contingencies, the ultimate resolution of any tax

matter may result in payments materially different from the amounts accrued.

We rely on our patents and other proprietary rights to provide exclusive rights to market certain

of our medicines and vaccines. If such patents and other rights were limited, invalidated, or

circumvented, our financial results could be adversely affected

Through patent and other proprietary rights, such as data exclusivity or supplementary protection certificates in Europe, we hold

exclusivity rights for several of our research-based medicines and vaccines. However, the protection that we can obtain varies in

its duration and scope. Furthermore, patents and other proprietary rights do not always provide effective protection for our

4 SANOFI FORM 20-F 2025

PART I
ITEM 3. Key Information

medicines and vaccines. We cannot be certain that we will obtain adequate patent protection for new medicines and vaccines

and technologies in important markets or that such protections, once granted, will last as long as originally anticipated.

For example, governmental authorities are increasingly looking to facilitate generic and biosimilar competition for existing

medicines and vaccines through new regulatory proposals intended to achieve, or resulting in, changes to the scope of patent or

data exclusivity rights and using accelerated regulatory pathways for generic and biosimilar approvals. At the EU level, the

proposed wide-ranging revision of the general pharmaceutical legislation may pose downside risks to innovation and

competitiveness in Europe, primarily due to amendments to regulatory exclusivities, the reduction of intellectual property (IP)

protections, and a stricter incentives framework for orphan medicinal products (OMPs). Such regulatory proposals could

adversely affect product exclusivity periods and otherwise make commercialization in the EU more burdensome.

Moreover, manufacturers of generics and biosimilars are increasingly seeking to challenge patent validity or coverage before the

patents expire, and manufacturers of biosimilars or interchangeable versions of the medicines are seeking to have their version

approved before the exclusivity period ends. Furthermore, in an infringement suit against a third party, we may not prevail, and

the decision rendered may not conclude that our patent or other proprietary rights are valid, enforceable, or infringed. Our

competitors may also avoid our patents. Even in cases where we ultimately prevail in an infringement claim, legal remedies

available for harm caused to us by such third party's infringement may be inadequate to make us whole. Moreover, a successful

result against a competing product for a given patent or in a specific country is not necessarily predictive of our future success

against another competing product or in another country because of local variations in the patents and patent laws.

In addition, if we lose patent protection because of an adverse court decision or a settlement, we face the risk that government

and private third-party payers and purchasers of medicines and vaccines may claim damages alleging they have over-reimbursed

or overpaid for a drug.

We also rely on unpatented proprietary technology, know-how, trade secrets and other confidential information, which we seek

to protect through various measures, including confidentiality agreements with licensees, employees, third-party collaborators,

and consultants who may have access to such information. If these agreements are breached or our other protective measures

should fail, then our contractual or other remedies may not be adequate to cover our losses.

In certain cases, to terminate or avoid patent litigation we or our collaboration partners may be required to obtain licenses from

the holders of third-party intellectual property rights. Any payments under these licenses may reduce our profits from such

medicines and vaccines and we may not be able to obtain these licenses on favorable terms or at all.

Third parties may also request a preliminary or permanent injunction in a country from a court of law to prevent us from

marketing a medicine or vaccine if they consider that we infringe their patent rights in that country. For example, Sanofi is or was

party to patent infringement proceedings in several countries initiated against us and Regeneron by Amgen Inc. relating to

Praluent in which Amgen Inc. requested injunctive relief (see Note D.22.b. to our consolidated financial statements included at

Item 18. of this annual report). If third parties obtain a preliminary or permanent injunction or if we fail to obtain a required license

for a country where valid third-party intellectual property rights as confirmed by a court of law exist, or if we are unable to alter

the design of our technology to fall outside the scope of third-party intellectual property rights, we may be unable to market

some of our medicines and vaccines in certain countries, which may limit our profitability and have a negative impact on our

financial results.

In addition, the pursuit of valid business opportunities may require us to challenge intellectual property rights held by others that

we believe were improperly granted, including through negotiation and litigation, and such challenges may not always be

successful. Third parties may claim that our medicines and vaccines infringe one or more patents owned or controlled by them.

Claims of intellectual property infringement can be costly and time-consuming to resolve, may delay or prevent product

launches, and may result in significant royalty payments or damages.

Furthermore, some countries may consider granting a compulsory license to a third party to use patents protecting an

innovator’s product, which limits the value of the patent protection granted to such products.

We have increased the proportion of biological therapeutics in our pipeline relative to traditional small-molecule medicines.

Typically, the development, manufacture, sale, and distribution of biological therapeutics is complicated by third-party

intellectual property rights (otherwise known as freedom to operate (FTO) issues), to a greater extent than for the small molecule

therapeutics, because of the types of patents allowed by national patent offices. Further, our ability to successfully challenge

third-party patent rights is dependent on the legal interpretation and case law of national courts. In addition, we expect to face

increasing competition from biosimilars in the future. With regulatory pathways available in the United States and Europe for

biosimilar drug approval, biosimilars can be a threat to the exclusivity of any biological therapeutics we sell or may market in the

future and can pose the same issues as the small-molecule generic threat described above. If a biosimilar version of one of our

medicines were to be approved, it could reduce our sales and/or profitability.

We currently hold trademark registrations and have trademark applications pending in many jurisdictions, any of which may be

the subject of a governmental or third-party objection, which could prevent the maintenance or issuance of the trademark. As

our medicines and vaccines mature, our reliance on our trademarks and trade dress to differentiate us from our competitors

increases and, as a result, our business could be adversely affected if we are unable to prevent third parties from adopting,

registering, or using trademarks and trade dress that infringe, dilute, or otherwise violate our rights.

If our patents and/or proprietary rights to our medicines and vaccines were limited or circumvented, our financial results could be

adversely affected.

ITEM 3. Key Information

Failure to comply with data ethics and privacy regulations could adversely affect our business

and reputation

We operate in an environment that relies on the collection, processing, analysis, and interpretation of large sets of patients’ and

other individuals’ personal data, and the operation of our business requires data to flow freely across borders of numerous

countries.

The legal and regulatory environment of data privacy is diversified, with regional legislation such as the General Data Protection

Regulation (GDPR) in Europe, the Personal Information Protection Law (PIPL) in China, and other significant privacy legislation,

including the California Consumer Privacy Act (CCPA) in the United States . The regulatory landscape continues to evolve with

increasingly fragmented requirements across jurisdictions, creating uncertainty and challenges to companies’ ability to put in

place operational policies and procedures to comply with applicable rules and regulations. These changes could result in

increased operational risk by limiting or preventing data transfer across borders, which may materially negatively impact our

activities, such as our ability to share data when conducting clinical studies (see also “— Data sovereignty regulations could

significantly impact Sanofi's global operations and strategic initiatives ” below). Any breach of such regulations could also incur

financial penalties and reputational harm.

Our increasing reliance on third-party partnerships and service providers introduces additional risks, as data breaches affecting

these partners could have direct implications for our operations and reputation.

Furthermore, the increasing volume of data processed and advances in new technologies, such as artificial intelligence (AI),

introduce new complexities in ensuring responsible data use, requiring sophisticated governance frameworks and specialized

expertise to effectively manage these emerging technologies while maintaining compliance and ethical standards. Failure in our

data governance and ethical use of personal data could affect our business and reputation. (see "— We may fail to develop or

take advantage of digitalization and prioritizing data as an organizational asset " below).

Risks relating to our business

Research, clinical development and regulatory approval processes present significant risks to our

pipeline success and portfolio renewal

Our future success is highly dependent on our pipeline of new products. Researching and developing new medicines or vaccines

is a costly, lengthy, and highly uncertain process and we have faced and may in the future face setbacks or failures in connection

with these and other aspects of our efforts to maintain or expand our pipeline of new products. To succeed in the highly

competitive biopharmaceutical industry, we must commit substantial resources each year to research and develop new

medicines and vaccines to compensate for decreasing sales of medicines or vaccines facing patent expiration and termination of

regulatory data exclusivity, introduction of lower-priced generics and biosimilars, or competition from new launches by

competitors that are perceived as being comparable or superior in efficacy or safety to our therapies. We must pursue both

research and early-, mid- and late-stage development to achieve a sustainable and well-balanced portfolio. In 2025, we spent

€ 7,842 million on research and development, representing 18.0% of our net sales. As part of an update to our strategy, we

announced in October 2023 our intent to increase our investment in research and development. Failure to invest with the

appropriate balance in the right technology platforms, disease areas, medicine or vaccine classes, geographic markets, and

licensing or acquisition opportunities could adversely impact the productivity of our internal pipeline. We may fail to improve our

development productivity sufficiently to sustain our pipeline.

We are researching and developing medicines with several potential indications, intended to address unmet medical needs in

markets with a low penetration of novel advanced therapies, or where no effective treatment is currently approved. We focus our

R&D strategy on medicines in immunology, rare diseases, neurology, and selectively in oncology. In 2021, Sanofi acquired

Translate Bio to accelerate the deployment of mRNA technology for the development of new vaccines, including for seasonal

influenza, and beyond vaccines, medicines where there is a strong unmet medical need. However, mRNA technology is still in its

early days and there can be no assurance that this technology will be able to produce strong results with an acceptable safety

profile. (see also “— We may fail to successfully identify external business opportunities or realize the anticipated benefits from

our strategic investments or divestments ” below).

The competitive landscape includes a high level of uncertainty including because numerous companies are working on or may be

evaluating similar targets to us. A medicine or vaccine considered as promising at the beginning of its development may become

less so if (among other things) a competitor addressing the same unmet need reaches the market earlier.

Over these research and development cycles, usually spanning several years, there is a substantial risk at each stage of

development that we will not achieve our goals of safety and/or efficacy and that we will decide to abandon a medicine or

vaccine in which we have invested substantial amounts of money and human resources. There can be no assurance that any of

our pipeline projects will be proven safe or effective or will receive marketing approval (see "Item 4. Information on the Company

— B.4. Global research & development").

Studies are increasingly designed with clinical endpoints of superiority, which means that failure to achieve those endpoints could

damage the medicine or vaccine's outlook and our overall development program. For instance, in 2025 we discontinued further

development on a vaccine candidate for extraintestinal pathogenic E. coli after indication of insufficient efficacy, and the SP0125

program for the prevention of respiratory syncytial virus-related disease in toddlers .

Interim results of our clinical trials do not necessarily predict final results, and product candidates believed to have performed

satisfactorily in preclinical studies and early clinical trials can nonetheless fail or obtain mixed results at a later stage, or fail to

obtain marketing approval. For instance, in May 2025, we announced mixed results for the itepekimab COPD (chronic obstructive

pulmonary disease) Phase 3 studies .

6 SANOFI FORM 20-F 2025

PART I
ITEM 3. Key Information

Participants in clinical trials of our products and product candidates or individuals using drugs similar to our product candidates

may suffer serious and unexpected adverse events or side effects that could delay or terminate clinical trial programs, require

additional or longer trials to gain approval, or result in clinical holds imposed by regulatory authorities pending receipt of

additional data.

We rely heavily on independent clinical investigators, contract research organizations (CROs), and other third-party service

providers to assist us in managing, monitoring, and otherwise carrying out our clinical trials; co-development partners can also be

involved. If our third-party service providers or co-development partners cannot adequately and timely fulfill their obligations to

us, or if the quality and accuracy of our clinical trial data are compromised due to their failure to adhere to our protocols or

regulatory requirements, or if they fail to meet deadlines, our development plans and regulatory reviews for marketing approvals

may be delayed or terminated, which would harm our business and negatively impact our stock price.

Also we have faced and may in the future face difficulties in recruiting and enrolling patients for clinical trials.

Decisions concerning the studies to be carried out can have a significant impact on the marketing strategy for a given medicine

or vaccine. Multiple in-depth studies, usually in Phase 4, can demonstrate that a medicine or vaccine has additional benefits,

thereby facilitating the marketing, but such studies are expensive and time consuming and may delay the medicine or vaccine's

submission to regulatory authorities for approval.

Obtaining a marketing authorization for a medicine or vaccine is a long and highly regulated process requiring us to present

extensive documentation and data to the relevant regulatory authorities. The regulatory approval pathway for our product

candidates may be uncertain, complex, expensive, and lengthy, and approval is never certain. Each regulatory authority may

impose its own requirements that can evolve over time, and regulatory authorities may change requirements for the approval of a

product candidate even after reviewing and providing comments or advice on a protocol for a clinical study. Also we may not be

able to successfully address all the comments received from regulatory authorities. For instance, in December 2025, the FDA

issued a complete response letter (CRL) on the new drug application for tolebrutinib to treat non-relapsing secondary

progressive multiple sclerosis (nrSPMS) in adult patients. Each regulatory authority may also delay or decline granting approval

regardless of whether a medicine or vaccine has already been approved in another country.

The FDA, EMA, or other regulatory authorities may disagree with our trial design, our interpretation of data from preclinical and

clinical studies, or the conclusions reached from our data. Further, regulatory authorities may not accept or agree with our

assumptions, estimates, calculations, or conclusions, or may interpret or weigh the importance of data differently, which may

delay, limit, impede or prevent regulatory approval. Also we may be unable to establish clinically meaningful endpoints that

regulatory authorities consider appropriate, which could delay, limit, impede or prevent advancement or marketing approval of

our product candidates.

If the results of our clinical trials are inconclusive or if there are safety concerns or serious adverse events associated with our

product candidates, we may fail to obtain or face delay in obtaining marketing approval; the approval for indications or patient

population may not be as broad as intended; the regulatory authorities may not accept the labeling claims that we believe would

be desirable for successful commercialization; the approved labeling may include significant use or distribution restrictions or

safety warnings, contraindications, or other limiting statements; and additional clinical trials may be required to support approval

or we may be subject to additional post-marketing testing requirements. Regulatory authorities may also withdraw or suspend

their approval of the drug or impose restrictions on its distribution in the form of a modified risk evaluation and mitigation

strategy (REMS) plan. Anticipated and/or observed safety concerns from novel immunomodulatory therapies may require

proactive and targeted risk mitigation to maintain positive benefit-risk for clinical trial participants and if mitigation efforts do not

adequately mitigate such concerns could result in clinical holds, delays or termination of clinical trials, increased regulatory

scrutiny, or an unfavorable reassessment of the benefit-risk profile including at the marketing approval stage, any of which could

adversely affect our pipeline development and results of operations.

In addition, following (or in some cases in parallel with) the marketing authorization, a dossier is also submitted to governmental

agencies and/or national or regional third-party payers for review. Health technology assessment bodies evaluate evidence on

the value of the new medicine or vaccine, assess the medical need it serves, and provide recommendations on the corresponding

appropriate reimbursement. Such analyses may require additional studies, including comparative studies, which may effectively

delay marketing, change the population for which the new medicine or vaccine is intended, and add costs to the development.

Our continuous investments in our research and development pipeline, and in launches of newly registered molecules, could

therefore result in increased costs without a proportionate increase in revenues, which would negatively affect our operating

results and profitability.

Furthermore, there can be no assurance that all medicines or vaccines approved or launched will achieve commercial success.

Also product extensions or additional indications may not be approved, limiting our ability to maximize the commercial potential

of existing medicines or vaccines.

Even after a medicine or vaccine reaches the market, certain developments following regulatory approval may reduce demand

for them. In particular, results from clinical studies following approval (including studies undertaken as post-approval

commitments) and information gathered through post-marketing surveillance, including relating to safety, efficacy or tolerability

of pharmaceuticals in general, have the potential to raise concerns among some prescribers and patients, may change the

benefit-risk assessment, may negatively affect the potential for commercialization, and may increase the risk of being required to

withdraw a product from the market by regulatory authorities, including due to FDA approval withdrawal on an expedited basis,

any of which could negatively affect sales or lead to increased volatility in market reaction.

SANOFI FORM 20-F 2025 7

PART I
ITEM 3. Key Information

The pricing and reimbursement of our medicines and vaccines are negatively affected by increasing cost

containment pressures and major policy shifts

The commercial success of our products is negatively affected by escalating pricing and access pressures across all markets due,

inter alia, to:

• Increasing price interdependency and international price referencing (IRP) pressure/shifts between countries:

– introduction of "most favored nation" (MFN) tying US reimbursement prices to a benchmark, comprising the G7 nations

(excluding the US) plus Denmark and Switzerland, giving rise to the potential for global rebalancing of drug prices between

the US and other countries, with an impact on launch sequencing and pricing corridors.

• Tighter cost-containment policies imposed by governments and other payers around the world:

– US federal government drug price controls, including MFN policy and Medicare drug price negotiations under the Inflation

Reduction Act (IRA);

– requirements for greater transparency around drug pricing and drug development costs;

– mandatory price cuts, renegotiations, industry payback and rebates;

– delisting from reimbursement and restrictions on the label population;

– access restrictions for high-priced innovative medicines;

– prescribing guidelines and binding medicine utilization controls;

– greater use of tendering and centralized procurement (national/regional/class-wide level);

– cross-country cooperation in price negotiations, contracting or procurement;

– shifting of the payment burden to US patients and access disruptions through copay accumulator and maximizer programs

as well as alternative funding programs;

– more aggressive formulary utilization management controls (including stepped therapy, strict prior authorization criteria,

formulary exclusions) by US insurers and pharmacy benefits managers (PBMs); and

– discriminatory and non-transparent pricing and procurement policies (e.g. government procurement restrictions, import

bans, and threats of pharma-specific tariffs) that favor domestic pharmaceutical companies.

• More complex health technology assessment (HTA) processes raising the bar for market entry, primarily in non-US markets:

– more stringent evidence and value requirements throughout the product lifecycle (e.g. comparative effectiveness, patient

preferences, real-world evidence, health economic modelling) by payers and HTA authorities;

– unreasonable thresholds for cost-effectiveness; and

– increasingly restrictive HTA decisions with significant variation across markets.

• Increased generic and biosimilar competition, accelerating price erosion while generating savings for future innovation:

– accelerated generics/biosimilars entry triggered by new US legislation and expected revised EU pharma legislation;

– next generation biosimilars coming to the market across major therapeutic areas;

– potential savings from increased biosimilar use, which are expected to be a cumulative $290 billion globally from 2023 to

2027 and could reach $383 billion, according to IQVIA’s recent Global Use of Medicines report; and

– evolving regulatory landscapes to support interchangeability (e.g. in the US and EU) and pharmacy substitution (e.g. in the

EU Nordic countries, Germany and France).

We are facing heightened policy uncertainty triggered by new policies in the US and in Europe, requiring us to rethink our global

launch sequencing, pricing and access strategies.

On December 19, 2025, we signed a voluntary MFN agreement with the US government ensuring that state Medicaid programs

can access certain of our medicines at the same prices available to other high-income nations. Although we secured a three-year

tariff exemption and near-term clarity during the three-year duration of the MFN agreement, uncertainty remains regarding final

MFN implementation rules and their potential implications for future product launches. In December, the US government also

announced three new MFN pricing demonstration models: Generating cost Reductions for US Medicaid (GENEROUS) a voluntary

program through which pharmaceutical manufacturers (including those, like Sanofi, that entered into MFN agreements) opt in to

providing MFN pricing to state Medicaid programs; Global Benchmark for Efficient Drug Pricing (GLOBE); and Guarding US

Medicare Against Rising Drug Costs (GUARD). GLOBE and GUARD are mandatory models for manufacturers who have not opted

in to participating in the GENEROUS program and cover both Medicare Part B (GLOBE) and Part D (GUARD). Each of these

payment demonstrations is set to last for a period of five years, whereas Sanofi's MFN agreement is only for a duration of three

years. While Sanofi’s MFN agreement is voluntary and time-bound, these commitments along with the broader context of the

payment demonstration programs described above could significantly constrain our commercial flexibility and may limit our

ability to launch certain new products in specific countries or markets where local pricing conditions would otherwise require

different pricing strategies. If we are unable to achieve acceptable pricing terms in a given market that are consistent with our

MFN obligations, we may be forced to delay or forgo product launches in that market entirely, thereby reducing potential

revenues and limiting patient access to our medicines and vaccines. Furthermore, the precedent established by voluntary MFN

arrangements and the evolving regulatory and political environment, particularly in major markets, may increase pressure on

pharmaceutical companies to accept MFN or comparable pricing mechanisms on a more widespread basis in the future, whether

through voluntary agreements, regulatory requirements, or legislative mandates. The implementation of MFN provisions also

presents operational complexities and may create downward pressure on prices across our portfolio, limiting our ability to

capture the value of innovation. Any of these factors could have a material adverse effect on our business, results of operations,

financial condition, and our ability to bring innovative treatments to patients worldwide.

In the United States , which accounted for 50.8% of our net sales in 2025, we are navigating a transformative landscape driven by

the combined and ripple effects of the MFN and the IRA pricing policies. While MFN focuses on Medicaid , future launches and the

direct-to-patient market, the IRA primarily targets Medicare high-expenditure medicines. The IRA continues to mandate price

negotiations for Medicare drugs, progressively expanding the number of drugs subject to negotiation each year from 10 Part D

drugs in 2026 to 20 per year from 2029 onward, with the exception of orphan drugs (regardless of the number of indications)

8 SANOFI FORM 20-F 2025

PART I
ITEM 3. Key Information

under the One Big Beautiful Bill Act. 2025 negotiation rounds have shown substantial price reductions, with increasing downward

pressure on US drug pricing over time. While Sanofi's current US portfolio has limited government channel exposure and Dupixent

is not currently expected to be impacted by IRA until 2031, this evolving legislation may impact our revenue growth and influence

our portfolio strategy in the medium to long term.

Furthermore, in commercial channels, we continue to face intensifying pricing pressure and gross-to-net (GTN) erosion from

payers and pharmacy benefit manager s (PBMs) (i.e. formulary exclusions, tighter utilization management, higher rebate demands,

accumulator/maximizer programs). With the three largest group purchasing organizations (GPOs) - Ascent, Zinc and Emisar - now

covering approximately 85% of prescription drug claims, consolidation has led to greater PBM GPO negotiating power with drug

manufacturers, thereby adversely impacting our sales.

In the US, we may also face rapidly shifting federal vaccine policy, healthcare funding cuts, supply chain challenges (due to high

dependency on API imports), and persistent trade and geopolitical tensions.

In Europe, regulatory changes, including EU Pharmaceutical Legislation reform, and EU HTA Regulation, are fundamentally

reshaping how medicines are valued, priced, and launched across Europe. This creates a more centralized and higher-risk access

environment, forcing companies to make strategic trade-offs between early broad market access and protecting global pricing

strategies. The proposed EU pharmaceutical legislation reform, expected in early 2026, aims to counterbalance MFN pressure

while ensuring Europe remains a viable launch region, though it introduces new market access challenges including reduced data

protection and potential forced launches in unprofitable markets. The EU HTA Regulation, effective since early 2025, centralizes

clinical assessment at the EU level while maintaining national pricing decisions. This introduces new timeline and resource

pressures, but offers potential for more harmonized patient access. The mandatory Joint Clinical Assessment has become

strategically critical for global evidence strategies.

Breaches of data security, disruptions of information technology systems and cyber threats could result

in financial, legal, competitive, operational, business, or reputational harm

Our business depends heavily on the use of interdependent information technology systems, including Internet-based systems

and digital tools. Certain key areas such as research and development, production and sales are largely dependent on our

information systems (including cloud-based computing) or those of third-party providers (including for the storage and transfer

of critical, confidential, sensitive, or personal information regarding our patients, clinical studies, vendors, customers, employees,

collaborators and others). We are therefore vulnerable to cybersecurity attacks and incidents, and misuse or manipulation of any

of these IT systems could result in exposure of confidential information or the modification of critical data.

We and our third-party service providers, suppliers, contract manufacturers, distributors or other contracting third parties use, to

the best of our ability, secure information technology systems for the protection of data and threat detection. Like many

companies, we may experience certain of the following events which pose a risk to the security and availability of these systems

and networks, and the confidentiality, integrity, and availability of our sensitive data: breakdown, outages, service disruption or

impairment, data loss or deterioration in the event of a system malfunction or increasing threat of data theft or corruption in the

event of a cyber-attack, security breach, industrial espionage attacks, insider threat attacks, cybercrimes, including state-

sponsored cybercrimes, malware, misplaced or lost data, programming or human errors or other similar events. Also, in the event

of an attack, regulatory and legislative frameworks worldwide (including in the United States and the European Union ) related to

the financing of terrorism impose increasing restrictions on payments of ransom. As a result, our ability to recover the data might

be limited. Therefore, our business continuity could be at risk if we are unable to recover data through back-ups and restorations.

In addition, several existing and forthcoming rules and laws – including NIS2, the European Health Data Space (EHDS), the Data

Act, the Cyber Resilience Act and the AI Act – are changing privacy and cybersecurity compliance requirements, and creating

new potential enforcement risks.

We are increasingly using generative AI to enhance our business processes. Although we have set up a governance body to

control the AI initiatives taken on a company-wide scale and have made a generative AI charter available to all our employees,

this new technology, like other AI technology, entails risks linked to transparency, fairness, data privacy and confidentiality, eco-

responsibility, and cybersecurity. These risks could result in unintended consequences such as unethical practices, business and

reputational harm, cyber-attacks, and security breaches (see “— We may fail to develop or take advantage of digitalization and

prioritizing data as an organizational asset ” below). Moreover, there is a global trend towards more comprehensive regulation of

AI that may require us to modify existing or adopt new compliance procedures, or developments that could impact the

effectiveness of and our ability to use AI tools.

Each of these events could negatively impact important processes, such as scientific research and clinical studies, the submission

of outcomes to health authorities for marketing authorizations, the functioning of production processes and the supply chain,

compliance with legal requirements, trade secrets, security strategies and other key activities, including Sanofi employees’ ability

to communicate between themselves as well as with third parties (see also “— Product liability claims could adversely affect our

business, results of operations and financial condition ” above). This could result in material financial, legal, competitive,

operational, business, or reputational harm.

Although we maintain relevant insurance coverage, this insurance may not be sufficiently available in the future to cover the

financial, business, or reputational losses that may result from an interruption or breach of our systems. For example, certain types

of cyber-attacks could be considered as an act of war subject to insurance exclusion.

The manufacture of our medicines and vaccines is technically complex, and supply interruptions,

product recalls or inventory losses caused by unforeseen events may reduce sales, adversely affect

our operating results and financial condition, delay the launch of new medicines and vaccines, and

negatively impact our image

Many of our medicines and vaccines are manufactured using technically complex processes with production constraints,

including the need for specialized facilities, trained and certified employees, and highly specific raw materials. We must ensure

that all manufacturing processes comply with (i) current Good Manufacturing Practices (cGMP), (ii) other applicable regulations

issued by governmental health authorities around the world, and (iii) our own quality standards. Third parties supply us with a

portion of our raw materials, active ingredients, finished drug products, medical devices and quality control testing , which

exposes us to the risk of a supply shortage or interruption especially if these suppliers are unable to manufacture our medicines

and vaccines on time or in line with quality standards or if they experience financial difficulties.

Epidemics and other public health crises expose us to risks of a slowdown or temporary suspension in the production of our active

pharmaceutical ingredients, raw materials, and some of our medicines and vaccines, and may have a material and adverse effect

on our manufacturing operations if they impact our principal production sites. Any of these factors could adversely affect our

business, operating results, or financial condition (see “Item 4. Information on the Company — B.7. Production and raw materials”

for a description of these outsourcing arrangements and “A failure in our crisis and business continuity management processes in

case of unpredictable events could have negative consequences for our business, operations and reputation” below).

Our business may require the transformation and adaptation of our plants to ensure the continuity of production of our

medicines and vaccines in sufficient quantities to satisfy demand. This may be necessary to meet the need to produce new

medicines and vaccines, or to ensure the scaling up production of products under development once approved. This need may

also result from new regulatory requirements. Furthermore, our biological medicines and vaccines are subject to the risk of

manufacturing stoppages or the risk of loss of inventory because of the difficulties inherent in the processing of biological

materials and the potential difficulties in accessing adequate amounts of raw materials meeting required standards. In addition,

specific storage and distribution conditions are required for many biological medicines and vaccines (for example, cold storage is

necessary for certain vaccines, insulins, and some clotting factor medicines). These production difficulties may also be

encountered during testing, which is a mandatory requirement prior to drug products being released.

The complexity of our production processes, as well as standards required subject us to certain risks, particularly because the

research and remediation of any identified or suspected problems may cause production delays, substantial expense, product

recalls, loss of sales or inventories, and delays in launches. This could adversely affect our operating results and financial

condition, and cause reputational damage and the risk of product liability (see “— Product liability claims could adversely affect

our business, results of operations and financial condition ” above). Our medicines and vaccines, and their compositions (including

the identification of potential unexpected or unspecified impurities), are increasingly scrutinized by health and safety agencies. In

addition, some of our production sites, and some of our suppliers’ and/or contractors’ sites, are in areas exposed to natural

disasters such as floods, earthquakes, and hurricanes (see “— Climate change or legal, regulatory or market measures to address

climate change may negatively affect our business and results of operations ” below). Such disasters could be exacerbated by

climate change. In the event of a major disaster, we could experience severe destruction or interruption of our operations and

production capacity at these sites.

When manufacturing disruptions occur, we may not have alternate manufacturing capacity, particularly for certain biologics. In

the event of manufacturing disruptions, our ability to use backup facilities or set up new facilities is more limited because

biologics are more complex to manufacture and generally require dedicated facilities. Even though we aim to have backup

sources of supply whenever possible, including by manufacturing backup supplies of our principal active ingredients at additional

facilities when practicable, we cannot be certain they will be sufficient if our principal sources become unavailable. Switching

sources and manufacturing facilities requires significant time and prior approval by health authorities. Additionally, we may be

subject to requirements to locate manufacturing facilities in the region where the manufactured medicines and vaccines are sold,

as a result of local country governmental initiatives or of obligations intended to ensure local supply chain capacity; that may

introduce additional complexity to our global supply chain due to the significant time and regulatory approvals required for such

local facilities to become operational, the significant investment required, and the need to reorganize supply chains that might

otherwise source supplies from other (non-local) regions in order to maximize potential efficiency and benefits.

Supply shortages generate even greater negative reactions when they occur with respect to life saving medicines with limited or

no viable therapeutic alternatives. Shortages of specific medicines and vaccines can have a negative impact on the confidence of

patients, customers, professional healthcare providers, health authorities and the image of Sanofi and may lead to lower sales.

A substantial share of the sales and income of Sanofi depends on the performance of certain key

medicines and vaccines

Our current strategy, as presented in December 2019 and updated in October 2023, focuses on key growth drivers in the key

disease areas of immunology, rare diseases, neurology, selectively in oncology, and vaccines. Nevertheless, market expansion,

acquisitions, investments and new launches of medicines and vaccines may not deliver the anticipated benefits. We may also

encounter delays or failures in our launch strategy (in terms of timing, pricing, market access, marketing efforts, and dedicated

sales forces), such that our medicines and vaccines may not deliver the expected benefits. The competitive environment for a

given medicine or vaccine may also have changed by the time of the actual launch, necessitating a modification of our initial

forecasts. The need to prioritize the allocation of resources may also cause delays in or hamper the launch or expansion of certain

medicines or vaccines.

10 SANOFI FORM 20-F 2025

PART I
ITEM 3. Key Information

Also, we currently generate a substantial share of our sales from certain key medicines and vaccines (see “Item 5. Operating and

Financial Review and Prospects — A.2.1. Net sales — 3/Net Sales – Biopharma segment”). For example, Dupixent generated net

sales of €15,714 million in 2025 , representing 36.0% of our net sales for the year, and is Sanofi’s biggest product in terms of sales.

Among our key medicines, Lantus, Lovenox, Plavix, Jevtana and Aubagio face generic or biosimilar competition on the market. In

2025 , Lantus was one of Sanofi’s leading medicines in terms of sales with net sales of €1,733 million. With respect to influenza,

which represented together with Covid 29.2% of vaccines net sales in 2025 , we may face potential challenges. The influenza

market is expected to have several new competitive entrants, including both standalone flu mRNA vaccines and COVID-flu

combinations, which could be on the market ahead of us. Additionally, the influenza market globally is subject to intense pricing

pressure, as well as a decrease in vaccination coverage, and anti-vaccine policies could further erode confidence in vaccines and

change the regulatory and/or access framework, especially in the US. The combination of such factors could result in a lowering

of revenue from sales of influenza vaccines. Beyfortus, which represen ted 22.4% o f our vaccines net sales in 2025 , is facing

competition from another monoclonal antibody, which could negatively impact our revenue in this area.

More generally, expiration of effective intellectual property protections for our medicines typically results in the market entry of

one or more lower-priced generic or biosimilar competitors, often leading to a rapid and significant decline in revenues from

those medicines (for information regarding ongoing patent litigation see Note D.22.b. to the consolidated financial statements

included at Item 18. of this annual report).

Furthermore, in general, if one or more of our key medicines or vaccines were to encounter problems (such as material product

liability litigation, unexpected side effects, product recalls, non-approval by the health authorities of a new indication for a

marketed medicine, adverse coverage or utilization guidelines, pricing pressure, and manufacturing or supply issues), the adverse

impact on our business, results of operations and financial condition could be significant.

We rely on third parties for the discovery, manufacture, marketing, and distribution of some

of our medicines and vaccines

Our industry is both highly collaborative and competitive, whether in the discovery and development of new medicines and

vaccines , in-licensing, marketing and distribution, or manufacturing activities. We expect that we will continue to rely on third

parties for key aspects of our business and we need to ensure our attractiveness as a potential partner.

We conduct several significant research and development programs and market some of our medicines or vaccines in

collaboration with other biotechnology and pharmaceutical companies. For example, we currently have a global strategic

collaboration with Regeneron on monoclonal antibodies for the development and commercialization of Dupixent, Kevzara and

SAR440340 (REGN3500- itepekimab) (see “Item 5. Operating and Financial Review and Prospects — A.1.7.1 Alliance

Arrangements with Regeneron Pharmaceuticals Inc.”). We rely upon Regeneron to successfully carry out their responsibilities

regarding the manufacture and supply of these collaboration antibodies (see “Item 4. Information on the Company — B. Business

Overview”). In May 2024, we announced a co-exclusive licensing agreement to develop novel flu-COVID-19 combination

vaccines with Novavax (see “— Research, clinical development and regulatory approval processes present significant risks to our

pipeline success and portfolio renewal ”) . We may also rely on partners to design and manufacture medical devices for the

administration of our medicines or vaccines. Finally, we may rely on partners for the development and commercialization of in-

vitro diagnostic tests used in clinical studies, and in-vitro diagnostic tests specified in the labeling of our medicines as necessary

or useful for the management of patients taking our medicines. As regards some medicines and vaccines launched or under

development for which we have a collaboration agreement with partners, the terms of the applicable alliance agreement may

require us to share profits and losses arising from commercialization of such medicines and vaccines with our partners. This

differs from the treatment of revenue and costs generated by other medicines and vaccines for which we have no alliance

agreement, and such profit sharing may deliver a lower contribution to our financial results.

We could also be subject to the risk that we may not properly manage the decision-making process with our partners. Decisions

may be controlled by or subject to the approval of our collaboration partners, who may have views that differ from ours. We are

also subject to the risk that our partners may not perform effectively, which could have a detrimental effect when our

collaboration partners are responsible for the performance of certain key tasks or functions, for example related to clinical trials

manufacturing or distribution. This risk is further increased by the growing number of distribution centers divested by Sanofi as

part of its global strategy and by the resulting growing externalization of distribution tasks and functions.

Any failures in the development process or differing priorities may adversely affect our business, including the activities

conducted through our collaboration arrangements. We also cannot guarantee that third-party manufacturers will be able to

meet our near-term or long-term manufacturing requirements, for internal reasons (e.g. in case of financial difficulties), reasons

directly related to their contractual relationship with Sanofi, or external reasons (e.g. in the event of a health crisis). For instance,

f ollowing the completion of the spin-off of EUROAPI in May 2022, EUROAPI became a third-party manufacturer and continues to

manufacture a certain number of active pharmaceutical ingredients for Sanofi. We are also subject to the risk that contract

research organizations or other vendors (for instance regarding digital activities) retained by us, or our collaboration partners,

may not perform effectively.

Any conflicts, difficulties or litigation with our partners during these agreements or at the time of their renewal or renegotiation,

or any disruption in the relationships with our partners, may affect the development, manufacturing, launch and/or marketing of

certain of our existing or potential new medicines or vaccines and may cause a decline in our revenues or otherwise negatively

affect our results of operations.

SANOFI FORM 20-F 2025 11

PART I
ITEM 3. Key Information

We are subject to the risk of non-payment by our customers (1)

Our customers, which consist principally of wholesalers, distributors, pharmacies, hospitals, clinics, and government agencies,

present risks related to delayed payments or even non-payment. This risk is accentuated by concentrations among distributors

and retailers, as well as by ongoing uncertainties in global credit markets and economic conditions, in particular in emerging

markets. As a result, we may be affected by fluctuations in the buying patterns of such customers. The United States presents

specific customer credit risk issues because of the concentrated pharmaceutical distribution system: in 2025 our three main

customers represented respectively 18% , 12% and 6% of our consolidated net sales, respectively. We are also exposed to large

wholesalers in other regions, particularly in Europe. An inability of one or more of these wholesalers to honor their debts to us

could adversely affect our financial condition (see Note D.34. to our consolidated financial statements included at Item 18).

In certain countries, some of our customers are public or subsidized health systems. The economic and credit conditions in these

countries could further extend the average collection period for accounts receivable, putting additional strain on our working

capital.

Global economic conditions and an unfavorable financial environment could have negative

consequences for our business (2)

Over the past several years, growth of the global pharmaceutical market has increasingly been tied to global economic trends. In

this context, a substantial and lasting slowdown or instability of the global economy, major national economies or emerging

markets could negatively affect the global pharmaceutical market's growth and, as a result, adversely affect our business.

Unpredictable geopolitical conditions that currently exist in various parts of the world could have a material negative impact on

our business, in particular the armed conflict between Russia and Ukraine, and ongoing or potential further conflicts in the Middle

East and rising geopolitical tensions between the US and China, two of our key markets. The consequences of these conflicts

remain uncertain, and will depend on developments outside Sanofi’s control, including but not limited to the duration and severity

of the conflicts, and the consequences of the ongoing and additional financial and economic sanctions imposed by governments

in response. Trade, economic, technological and military conflicts could disrupt supply chains, raise raw material costs, and affect

clinical and manufacturing operations and business strategy. Other related issues have arisen or are arising such as regional

instability; geopolitical uncertainties; adverse effects on fuel and energy costs, supply chains, macroeconomic conditions,

inflation, and currency exchange rates in various regions of the world; and exposure of third parties to gas shortages. Collectively,

such unstable conditions could, among other things, disturb the international flow of goods and increase the costs and difficulties

associated with international transactions.

Unfavorable economic conditions have reduced the sources of funding for national social security systems, leading to austerity

measures including heightened pressure on drug prices, increased substitution of generic drugs, and the exclusion of certain

medicines from formularies among others (see “— The pricing and reimbursement of our medicines and vaccines are negatively

affected by increasing cost containment pressures and major policy shifts ” above).

The challenging economic environment could also negatively impact our net sales. In regions with high unemployment, rising

inflation, or limited third-party payer systems, patients may turn to more affordable generic alternatives, delay treatments, or

reduce observance to cut costs. In the United States there has been a significant increase in the number of beneficiaries in the

Medicaid program, under which sales of pharmaceuticals are subject to substantial rebates and, in many US states, to formulary

restrictions limiting access to brand-name drugs, including ours. Additionally, rising healthcare costs have prompted some

employers to transfer a greater share of these costs to their employees, which further decreases demand for brand-name

pharmaceuticals and intensifies downward pressure on prices.

Should global economic conditions worsen, or in the event of default or failure of major players including wholesalers or public

sector buyers financed by insolvent states, Sanofi's financial situation, profitability, operational results, and product distribution

channels could be adversely affected. See also “— We are subject to the risk of non-payment by our customers” above.

A failure in our crisis and business continuity management processes in case of unpredictable events

could have negative consequences for our business, operations, and reputation

We have increased crisis preparedness and response in recent years due to crises such as the COVID-19 pandemic, the ongoing

war in Ukraine and conflicts in the Middle East. Nevertheless, unpredictable and extraordinary internal or external events, or a

combination of escalating events that may occur as a result of a large scale cyber-attack (see also “— Breaches of data security,

disruptions of information technology systems and cyber threats could result in financial, legal, competitive, operational,

business, or reputational harm ” above), a pandemic or natural disasters, could result in the failure of critical processes within

Sanofi or a third party on whom we rely. Moreover, lack of resources and/or low maturity level in crisis management of our service

providers faced with an increasing number of major international crises may hamper our ability to implement our business

continuity plans. Such failure or limited implementation of our business continuity plans may adversely impact our business,

operations, and reputation.

The occurrence of such unforeseen events may also heighten other risks such as a disruption or temporary suspension in

production of active pharmaceutical ingredients, raw materials and some of other products and/or lead to manufacturing delays

or disruptions and supply chain interruptions (including to the extent those measures apply to our third-party suppliers) and may

have an adverse effect on our business (see “— The manufacture of our medicines and vaccines is technically complex, and

supply interruptions, product recalls or inventory losses caused by unforeseen events may reduce sales, adversely affect

our operating results and financial condition, delay the launch of new medicines and vaccines, and negatively impact our image ”

12 SANOFI FORM 20-F 2025

PART I
ITEM 3. Key Information

above). Also, a sudden increase in demand for selected medicines and vaccines in the event of a crisis can result in short-term

unavailability or shortages of raw materials.

Climate change or legal, regulatory or market measures to address climate change may negatively affect

our business and results of operations

Climate change resulting from increased concentrations of carbon dioxide and other greenhouse gases in the atmosphere could

present both physical and transition risks to our operations.

Physical risks include adverse impacts on global temperatures, weather patterns and the frequency and severity of extreme

weather and natural disasters. Natural disasters and extreme weather conditions, such as a hurricane, tornado, wildfire, or

flooding, may pose physical risks to our facilities and disrupt the operation of our supply chain. The impacts of the changing

climate on water resources may result in water scarcity, limiting our ability to access sufficient high-quality water in certain

locations, which may increase operational costs.

Concern over climate change may also result in new or additional legal or regulatory requirements, designed to reduce

greenhouse gas emissions and/or mitigate the effects of climate change on the environment. If such laws or regulations were to

be more stringent than current legal or regulatory obligations (e.g. increased carbon taxation risk), we may experience disruption

in, or an increase in the costs associated with sourcing, manufacturing, and distribution of our medicines and vaccines, which may

adversely affect our business, results of operations or financial condition.

The use of social media platforms and communication technologies present risks and challenges

for our business and reputation

The use of social media, technologies and digital tools to communicate about our medicines and vaccines and about diseases or

to provide health services requires specific attention, monitoring programs, and moderation of comments. Political and market

pressures may be generated by social media because of rapid news cycles. This may result in commercial harm, overly restrictive

regulatory actions, and erratic share price performance. In addition, unauthorized communications, such as press releases or

posts on social media purported to be issued by Sanofi, may contain information that is false or otherwise damaging and could

have an adverse impact on our image and reputation and on our stock price. Negative or inaccurate posts or comments about

Sanofi, our business, directors, or officers on any social networking website could seriously damage our reputation. In addition,

our employees and partners may use social media and mobile technologies inappropriately, which may give rise to liability for

Sanofi, or which could lead to breaches of data security, loss of trade secrets or other intellectual property or public disclosure of

sensitive information. Such uses of social media and mobile technologies could have an adverse effect on our reputation,

business, financial condition, and results of operations.

Data sovereignty regulations could significantly impact Sanofi's global operations and strategic

initiatives

Data sovereignty regulations increasingly restrict cross-border data flows critical to our activities. Accelerating geopolitical

tensions have transformed data sovereignty from focusing primarily on privacy concerns to focusing on national security

imperatives, as evidenced by the US Data Security Program (DSP). Our early-stage pipeline development, M&A activities, digital

transformation initiatives, AI scaling ambitions, and end-to-end supply chain all depend on cross-border data flows now subject

to increasing restrictions. Such rules and regulations could have a material adverse impact on our business, results of operations

or financial condition, including due to our diverse portfolio, our extensive research activities, the fragmented digital landscape

with which we are forced to comply, our extensive third-party relationships, and our global supply chain. These risks expose us to

potential operational disruptions, increased compliance costs, regulatory penalties, and compromised innovation capabilities.

Risks relating to Sanofi’s structure and strategy

We may fail to successfully identify external business opportunities or realize the anticipated benefits

from our strategic investments or divestments

We pursue a strategy of selective acquisitions, in-licensing, and collaborations to reinforce our pipeline and portfolio. We are also

proceeding with selective divestments to focus on key business areas. The implementation of this strategy depends on our ability

to identify transaction opportunities, mobilize the appropriate resources to enter into agreements in a timely manner, and

execute these transactions on acceptable economic terms, especially in an increased competitive landscape where multiple large

pharmaceutical companies will face patent cliffs by 2030. Moreover, entering into in-licensing or collaboration agreements

generally requires the payment of significant “milestones” well before the relevant medicines and vaccines reach the market,

without any assurance that such investments will ultimately become profitable in the long term (see Note C. to our consolidated

financial statements included at Item 18 of this annual report and “— We rely on third parties for the discovery, manufacture,

marketing, and distribution of some of our medicines and vaccines ” above). Once a strategic transaction is agreed upon with a

third party, we may not be able to complete the transaction in a timely manner or at all or achieve the anticipated benefits.

For example, following the divestment of Opella that was completed in April 2025, our remaining business is smaller and less

diversified than previously. Post-divestment we have greater relative exposure to the global pharmaceuticals and vaccines

markets and the associated risks and will no longer benefit from exposure to the Consumer Healthcare market we had prior to

divestment of the Opella business. Also, our remaining holding in Opella may fall in value if Opella's strategy does not deliver the

expected benefits.

For newly acquired activities or businesses, our growth objectives could be delayed or ultimately not realized, and expected

synergies could be adversely impacted if, for example we are unable to integrate those activities or businesses quickly or

efficiently, key employees leave, or we have higher than anticipated integration costs.

SANOFI FORM 20-F 2025 13

PART I
ITEM 3. Key Information

The Translate Bio acquisition, completed in 2021, may not generate the expected results in terms of developing new mRNA-

based vaccines to meet our existing or future needs. In 2025, we acquired Blueprint Medicines Corporation; h owever, we may

face risks of delays in development timelines as there is still uncertainty in the progress of early-stage pipeline immunology, and

hence we may not realize the expected benefits of the acquisition.

We may also miscalculate the risks associated with business development transactions at the time they are made or may lack the

resources or ability to access all the relevant information to evaluate such risks properly, including regarding the potential of

research and development pipelines, manufacturing issues, tax or accounting issues, compliance issues, or the outcome of

ongoing legal and other proceedings. It may also take a considerable amount of time and be difficult to implement a risk analysis

and risk mitigation plan after the acquisition of an activity or business is completed due to lack of historical data. Acquired

businesses may not always be in full compliance with legal, regulatory or Sanofi standards, including, for example, current Good

Manufacturing Practices (cGMP), which can be costly and time consuming to remedy. As a result, risk management and coverage

of such risks, particularly through insurance policies, may prove to be insufficient or ill-adapted.

With respect to divestments, their financial benefit could be impacted if we face significant financial claims or significant post-

closing price adjustments. Furthermore, the value of the assets to be divested may deteriorate while we are in the process of

executing our divestment strategy, with the risk that we do not realize the anticipated benefits.

Because of the active competition among pharmaceutical groups for business development opportunities, there can be no

assurance of our success in completing these transactions when such opportunities are identified.

The globalization of our business exposes us to increased risks in specific areas

As part of the presentation of our strategy in December 2019 and updated in October 2023 , we identified our strong presence in

China among our core drivers, with revenue amounting to 6.0% of our net sales in 2025 .

The difficulties in operating in emerging markets, a significant decline in the anticipated growth rate or an unfavorable movement

in the exchange rates of currencies against the euro could impair our ability to take advantage of growth opportunities and could

adversely affect our business, results of operations or financial condition. For instance, if a long-lasting epidemic and prolonged

or repeated restrictive measures to control the outbreak were to result in an economic slowdown in any of our targeted markets,

it would reduce our sales due to lower healthcare spending on other diseases and fewer promotional activities, and could

significantly impact our business operations. Furthermore, it is not possible to predict if or how such a health crisis would impact

any affected jurisdiction, or to what extent (see also “— Global economic conditions and an unfavorable financial environment

could have negative consequences for our business ” above).

Emerging markets also expose us to more volatile economic conditions; legal, regulatory and political instability, both globally and

locally (including a backlash in certain areas against free trade); competition from multinational or locally based companies that

are already well established in these markets; the inability to adequately respond to the unique characteristics of emerging

markets (particularly with respect to their underdeveloped judicial systems and regulatory frameworks); difficulties in recruiting

qualified personnel or maintaining the necessary internal control systems; difficulties that may adversely affect our ability to

supply our medicines and vaccines; potential exchange controls; weaker intellectual property protection; higher crime levels

(particularly with respect to counterfeit products); and compliance issues including corruption and fraud (see particularly

“— Claims and investigations relating to ethics and business integrity, competition law, marketing practices, pricing, human rights

of workers and other legal matters could adversely affect our business, results of operations and financial condition ” above).

Given the increasing globalization of our business, if relations between the United States , European Union countries and other

governments deteriorate, our business and investments in such markets may also be adversely affected. For example, the

proposed federal BIOSECURE Act in the United States would prohibit federal agencies from entering into certain contracts with

or incurring expenditures related to companies that have specified commercial connections with “biotechnology companies of

concern” (the identification criteria for which have not been determined, and the list of which has not been defined and could be

very extensive, including companies in China); if enacted, that proposed Act or similar provisions could restrict our ability to

contract or collaborate with such biotechnology companies. This, in turn, could materially and adversely affect our or our

collaboration partners’ ability to manufacture or supply marketed and potential new medicines and vaccines, or to advance our or

our collaboration partners’ preclinical research, which could materially and adversely affect our business and prospects.

We may fail to develop or take advantage of digitalization and prioritizing data as an organizational

asset

We have undertaken several digital initiatives, such as the implementation of AI across our business. For example, in research and

development, we have built multiple AI programs to reduce research times through improved predictive modelling. We are also

seeking to automate time-consuming activities, enabling research and development teams to scale and accelerate research

processes and improve potential target identification in therapeutic areas such as immunology, oncology and neurology. In

manufacturing and supply, we have developed an in-house AI-enabled yield optimization solution that delivers higher yield levels

and optimizes usage of raw materials.

Our success in these efforts will depend on many factors including data availability; entering into successful partnerships and

alliances with technology companies (such as the AI collaboration with Formation Bio and OpenAI announced in May 2024, aimed

at building AI-powered software to accelerate drug development ); a profound transformation of our organization; a cultural

change among our employees, and the development of relevant skills; our ability to adopt AI agents; attracting and retaining

employees with appropriate skills and mindsets in a tight labor market; and successfully innovating across a variety of technology

fields, while seeking to comply with evolving external regulations. The success of digital initiatives will also depend on our ability

to shift our culture to a data-driven culture and to transform the architecture of our business process designs to integrate AI. This

calls for management of data as an asset and the definition of a robust life-cycle management process for data that is applied

consistently across Sanofi. In recent years, we have accelerated our digital transformation, including in the ways we engage and

14 SANOFI FORM 20-F 2025

PART I
ITEM 3. Key Information

interact with our stakeholders. However, there is no guarantee that our efforts towards digital transformation will succeed. More

generally, we may fail to capture the benefits of AI, digitalization and valuing data as an enterprise asset at an appropriate cost

and/or in a timely manner, and/or enter into appropriate partnerships. Competitors, including new entrants such as tech

companies, may outpace us in this fast-moving area. If we fail to adequately integrate digital capabilities into our organization

and business model, we could lose patients and market share. This could have an adverse impact on our business, prospects, and

results of operations. We may also become dependent on certain technologies developed by third-party AI service providers,

leading to the risk of our own failure to develop internal technology and risks of loss of the use of the related AI tools in the event

of interruption or breaches of the relationship with such third-party suppliers. Because AI is an emerging technology, it is possible

that our use of AI technologies may not have the intended effects or benefits, such as increasing efficiency. In addition, the use

of AI technologies presents certain risks, including the use of personal data as described above (see “— Failure to comply with

data ethics and privacy regulations could adversely affect our business and reputation " above). In addition, AI tools and

algorithms may be flawed or trained on content without the necessary intellectual property rights or other legal rights or

permissions; data sets may not be appropriate for the intended use, of poor quality, or contain biased information; and

inappropriate or controversial data practices could be applied by third parties, data scientists, engineers, and/or end-users. If

such risks materialize or the outputs that AI produces or assists in producing are deficient or inaccurate, we could be subjected to

potential legal liability and reputational harm. Furthermore, use of AI may lead to the release of confidential information which

may impact our ability to realize the benefits of our data, including intellectual property.

Misuse of such technologies could negatively affect our reputation, disrupt our operations, or otherwise have a material adverse

impact on our financial results and could also subject us to legal and reputational risks.

We may fail to accelerate our operational efficiency and execute our transformation program

As part of the presentation of the next chapter of our Play to Win strategy in October 2023, we announced our intent to improve

our operational efficiencies to fund growth. To deploy our strategy, we must also disrupt our normal course of business and

transform our operations. Nevertheless, we may not succeed in federating employees behind the transformation program, which

may hamper our ability to execute such organizational changes. Besides, there is no guarantee that we will be able to fully deliver

these operating efficiencies.

Unsuccessful management of sustainability (environmental, social and governance) matters

could adversely affect our reputation and we may experience difficulties meeting the expectations

of our stakeholders

Companies are increasingly expected to behave in a responsible manner on a variety of sustainability matters, by governmental

and regulatory authorities, counterparties such as vendors and suppliers, customers, investors, the public at large and others. This

context, driven in part by a rapidly changing regulatory framework in Europe, is raising new challenges and influencing strategic

decisions that companies must take if they wish to optimize their positive impact and mitigate their negative impact on

sustainability matters. These evolving regulatory requirements are also likely to result in increased costs and complexities of

compliance to collect, measure and report on the relevant ESG-related information, and may expose us to additional regulatory,

litigation and reputational risk. Given recent political and geopolitical pressures, there is also the possibility that some or part of

these rules or regulations are rolled back or amended, in which case we would face additional compliance costs and, depending

on such changes, we may face other adverse effects described below.

We have adopted a sustainability strategy that aims to tackle the impact of environmental changes on health and healthcare by

improving sustainable and equitable access to our medicines and vaccines, by reducing the environmental impact of our own

operations, and where possible by contributing through collective efforts to reduce healthcare systems' environmental footprints

and improve their resilience.

However, despite our ambitions we may be unable to meet our sustainability or other strategic objectives efficiently, on time, or

at all.

Furthermore, statements about our ESG-related initiatives and goals, and progress against those goals, may be based on

standards for measuring progress that are still developing, internal controls and processes that continue to evolve and

assumptions that are subject to change in the future.

We may also be unable to meet the ever more demanding criteria used by rating agencies in their sustainability assessments

process, leading to a downgrading in our ratings. Such ratings are increasingly used by major institutional investors to inform their

investment decisions.

Depending on sustainability assessments, our ability to fulfill our sustainability strategy, and on the rapidly changing views on

acceptable levels of action across a range of sustainability topics from investors, we may be unable to meet society’s or investors’

expectations or the targets or goals contained in our sustainability strategy, in which case our reputation may be harmed; we may

face increased compliance or other costs; and interest in subscribing to securities issued by us, and our ability to participate in

the debt and equity markets, may decrease. In addition, we could be criticized for the scope or nature of such initiatives or goals,

or for any revisions to these goals.

In addition, in recent years “anti-ESG” sentiment has gained momentum across the US, with several states and Congress having

proposed or enacted “anti-ESG” policies, legislation, or initiatives or issued related legal opinions, and the US President having

issued an executive order opposing diversity equity and inclusion (DEI) initiatives in the private sector. The anti-ESG and anti-DEI-

related policies, legislation, initiatives, litigation, scrutiny and other actions could result in additional compliance obligations,

Sanofi becoming the subject of investigations and enforcement actions, or otherwise suffering reputational harm.

SANOFI FORM 20-F 2025 15

PART I
ITEM 3. Key Information

Our success depends in part on our senior management team and other key employees and our ability to

attract, integrate and retain key personnel and qualified individuals in the face of intense competition

Our success depends on the expertise of our senior management team and other key employees. In 2025, there

were 2,282 “Senior Leaders” within Sanofi. In addition, we rely heavily on recruiting and retaining talented people to help us meet

our strategic objectives. We face intense competition for qualified individuals for senior management positions, or in specific

geographic regions or in specialized fields such as clinical development, biosciences and devices, or digital and AI. Our ability to

hire qualified personnel also depends in part on our ability to reward performance, incentivize our employees and pay

competitive compensation. The inability to attract, integrate and/or retain highly skilled personnel, in particular those in

leadership positions, may weaken our succession plans, may materially adversely affect the implementation of our strategy and

our ability to meet our strategic objectives, and could ultimately adversely impact our business or results of operations.

Environmental and safety risks of our industrial activities

Risks from manufacturing activities and the handling of hazardous materials could adversely affect

our results of operations and reputation

Manufacturing activities, such as the chemical manufacturing of the active ingredients in our medicines and vaccines and the

related storage and transportation of raw materials, products and waste, expose us to risks of industrial accidents that may lead

to discharges or releases of hazardous substances or other events that can cause personal injury, property damage and

environmental contamination, and may result in additional operational constraints, including the shutdown of affected facilities

and/or the imposition of civil, administrative, criminal penalties and/or civil damages, and affect Sanofi’s reputation.

The occurrence of an industrial accident may significantly reduce the productivity and profitability of a particular manufacturing

facility and adversely affect our operating results and reputation. Although we maintain property damage, business interruption

and casualty insurance that we believe is in accordance with customary industry practices, this insurance may not be adequate to

fully cover all potential hazards incidental to our business.

Management of the historical contamination related to our past industrial activities could adversely

impact our results of operations and reputation

The environmental laws of various jurisdictions impose actual and potential obligations on our Company to manage and/or

remediate contaminated sites. These obligations may relate to sites (i) that we currently own or operate; (ii) that we formerly

owned or operated; or (iii) where waste from our operations was disposed.

These environmental remediation obligations could reduce our operating results. Sanofi accrues provisions for remediation when

our management believes the need is probable and that it is reasonably possible to estimate the cost (see Note D.22 to our

consolidated financial statements included at Item 18 of this annual report). Our provisions for these obligations may be

insufficient if the assumptions underlying these provisions prove incorrect or if we are held responsible for additional, currently

undiscovered contamination. These judgments and estimates may later prove inaccurate, and any shortfalls could have an

adverse effect on our results of operations and financial condition. For more detailed information on environmental policies and

issues, see “Item 4. Information on the Company — B.9. Health, Safety and Environment" and Notes "B.12. Provisions for risks" and

"D.19.3. Other provisions" to our consolidated financial statements included at Item 18 of this annual report.

We are or may become involved in claims, lawsuits and administrative proceedings relating to environmental matters.

Some current and former Sanofi subsidiaries have been named as “potentially responsible parties” or the equivalent under

the US Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (CERCLA, also known

as “Superfund”), and similar statutes or obligations in France, Germany, Italy, Brazil and elsewhere. As a matter of statutory or

contractual obligations, we and/or our subsidiaries may retain responsibility for environmental liabilities at some of the sites of our

predecessor companies, or of subsidiaries that we demerged, divested, or may divest. We have disputes outstanding regarding

certain sites no longer owned or operated by Sanofi. An adverse outcome in such disputes might have an adverse effect on our

operating results. See Note D.22.d to our consolidated financial statements included at Item 18 of this annual report and

“Item 8. Financial Information — A. Information on Legal or Arbitration Proceedings”.

Environmental regulations are evolving. For example, in Europe, new or evolving regulatory regimes include the Registration,

Evaluation, Authorization and Restriction of Chemicals Regulation (which may include, in the future, a restriction on per- and

adopted Urban Wastewater Treatment Directive, as well as other regulations aimed at protecting public health or preventing

climate change. Stricter environmental, safety and health laws and enforcement policies could result in substantial costs and

liabilities to Sanofi and could subject our handling, manufacture, use, reuse or disposal of substances or pollutants, site restoration

and compliance to more rigorous scrutiny than is currently the case. Consequently, compliance with these laws could result in

capital expenditures as well as other costs and liabilities, thereby adversely affecting our business, results of operations or

financial condition.

PART I
ITEM 3. Key Information

Risks related to financial markets (3)

Fluctuations in currency exchange rates could adversely affect our results of operations

and financial condition

Because we sell our medicines and vaccines in numerous countries, our results of operations and financial condition could be

adversely affected by fluctuations in currency exchange rates. We are particularly sensitive to movements in exchange rates

between the euro and the US dollar, the Japanese yen, the Chinese yuan, and currencies in emerging markets. In 2025 , 50.8% of

our net sales were generated in the United States , 21.0% in Europe, and 28.2% in the Rest of the World region (see the definition

in “Item 5. Operating and Financial Review and Prospects — A. Operating results”), including countries that are, or may in future

become, subject to exchange controls (including 6.0% in China and 3.2% in Japan). While we incur expenses in those currencies,

the impact of currency exchange rates on these expenses does not fully offset the impact of currency exchange rates on our

revenues. As a result, currency exchange rate movements can have a considerable impact on our earnings. When deemed

appropriate and when technically feasible, we enter into transactions to hedge our exposure to foreign exchange risks. These

efforts, when undertaken, may fail to offset the effect of adverse currency exchange rate fluctuations on our results of operations

or financial condition. For more information concerning our exchange rate exposure, see “Item 11. Quantitative and Qualitative

Disclosures about Market Risk.”

Risks relating to an investment in our shares or ADSs

Foreign exchange fluctuations may adversely affect the US dollar value of our ADSs and dividends

(if any) regardless of our operating performance

Holders of American depositary shares (ADSs) face exchange rate risks. Our ADSs trade in US dollars and our shares trade in

euros. The value of the ADSs and our shares could fluctuate substantially as the exchange rates between these currencies

fluctuate. When we pay dividends, they would be denominated in euros. Fluctuations in the exchange rate between the euro and

the US dollar will affect the US dollar amounts received by owners of ADSs upon conversion by the depositary of cash dividends,

if any. Moreover, these fluctuations may affect the US dollar price of the ADSs on the NASDAQ Global Select Market (NASDAQ)

whether or not we pay dividends, in addition to any amounts that a holder would receive upon our liquidation or in the event of a

sale of assets, merger, tender offer or similar transaction denominated in euros or any foreign currency other than US dollars.

Persons holding ADSs rather than shares may have difficulty exercising certain rights as a shareholder

Holders of ADSs may have more difficulty exercising their rights as a shareholder than if they directly held shares. For example, if

we issue new shares and existing shareholders have the right to subscribe for a pro rata portion of the new issuance, the

depositary is allowed, at its own discretion, to sell this right to subscribe for new shares for the benefit of the ADS holders instead

of making that right available to such holders. In that case, ADS holders could be substantially diluted. Holders of ADSs must also

instruct the depositary how to vote their shares. Because of this additional procedural step involving the depositary, the process

for exercising voting rights will take longer for holders of ADSs than for holders of shares. ADSs for which the depositary does not

receive timely voting instructions will not be voted at any meeting. US investors may have difficulty in serving process or

enforcing a judgment against us or our directors or executive officers.

Sales of our shares may cause the market price of our shares or ADSs to decline

Sales of large numbers of our shares, or a perception that such sales may occur, could adversely affect the market price for our

shares and ADSs. L’Oréal, our largest shareholder, is not subject to any contractual restrictions on the sale of the shares it holds in

our Company. L’Oréal does not consider its stake in Sanofi as strategic, and completed an off-market block trade representing

2.3% of our share capital which was bought back by Sanofi in February 2025. See “Item 7. Major Shareholders and Related Party

Transactions" below.

Our largest shareholder owns a significant percentage of the share capital and voting rights of Sanofi

Following our buy-back of a block of shares from L’Oréal in February 2025, and after cancellation of said shares, as of December

31, 2025 L’Oréal held 7.27% of Sanofi’s share capital and 13.10% of Sanofi’s effective voting rights (excluding treasury shares).

Individuals linked to L’Oréal currently serve on Sanofi’s Board of Directors. For as long as L’Oréal retains its interest in our share

capital and voting rights, it will remain in a position to exert influence in the appointment of directors and officers of Sanofi and in

other corporate actions that require shareholder approval.

Item 4. Information on the Company

Introduction

Sanofi is an R&D driven, AI-powered biopharma company committed to improving people’s lives and delivering compelling

growth. We apply our deep understanding of the immune system to invent medicines and vaccines that treat and protect millions

of people around the world, with an innovative pipeline that could benefit millions more. Our team is guided by one purpose: we

chase the miracles of science to improve people’s lives; this inspires us to drive progress and deliver positive impact for our

people and the communities we serve, by addressing the most urgent healthcare, environmental, and societal challenges of our

time.

In the remainder of this section, medicines and vaccines are referred to either by their international non-proprietary name (INN)

or their brand name, which is generally exclusive to the company that markets it. In most cases, the brand names of our medicines

and vaccines, which may vary from country to country, are protected by specific registrations. In this document, medicines and

vaccines are identified by their brand names used in France and/or in the US.

T he segment information presented by Sanofi consists of a single operating segment: Biopharma.

The Biopharma operating segment comprises commercial operations and research, development and production activities

relating to the Specialty Care, General Medicine s, and Vaccines franchises plus support and corporate functions, for all

geographical territories. It also includes revenues generated from the manufacture of Consumer Healthcare products invoiced

to Opella Healthcare SAS (Opella), which constitutes a related party with effect from April 30, 2025, the deconsolidation date,

corresponding to the closing of Sanofi's sale of a controlling stake of approximately 50% in Opella to Clayton, Dubilier & Rice

(CD&R) (for more information, see “Item 4. Information on the Company — B. Business overview — B.3 Opella”). Those

revenues, which before the deconsolidation date represented intragroup transactions classified within continuing operations,

are presented within Other revenues in the income statement. The Biopharma operating segment also includes the purchase

price of Biopharma products manufactured by Opella.

The “Other” category comprises primarily, but not exclusively, Consumer Healthcare activities not transferred on the effective

date of loss of control of Opella. These are primarily (i) hospital sales of Opella products in China, the transfer of which will be

finalized no earlier than 2028 ; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to hold the

capital (Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in

connection with the separation, the parties reserving the right to discuss the transfer of that entity during the term of the

distribution agreement); and (iii) sales of the Gold Bond product range, which are continuing in the U S through the retained

subsidiary Gold Bond LLC (holder of the associated worldwide property rights).

A. History and development of the Company

The current Sanofi company was incorporated under the laws of France in 1994 as a société anonyme , a form of limited liability

company, for a term of 99 years. Since May 2011, we have operated under the commercial name “Sanofi” (formerly known as

Sanofi-Aventis). Our registered office is located at 46, avenue de la Grande Armée – 75017 Paris – France , our main telephone

number is +33 1 53 77 40 00, and our website (which contains information about the company and information filed with and

provided to the SEC) is www.sanofi.com. Our principal US subsidiary’s office is located at 100 Morris Street, Morristown, New

Main events over the last three years

On March 13, 2023, Sanofi and Provention Bio, Inc. (Provention), a US-based publicly-traded biopharmaceutical company

developing therapies to prevent and intercept immune-mediated diseases including type 1 diabetes, entered into an agreement

under which Sanofi acquired the outstanding shares of Provention common stock for $25.00 per share in an all-cash

transaction valued at approximately $2.8 billion. On April 27, 2023, Sanofi announced the completion of its acquisition of

Provention. The acquisition added Tzield/Teizeild (teplizumab), a therapy for type 1 diabetes, to our portfolio .

On May 30, 2024, Sanofi announced that it had completed the acquisition of Inhibrx, Inc. (Inhibrx), a publicly-traded,

clinical-stage biopharmaceutical company focused on developing a pipeline of novel biologic therapeutic candidates in

oncology and orphan diseases. The acquisition added efdoralprin (formerly INBRX-101) to Sanofi’s rare disease development

portfolio. Under the terms of the merger agreement, Sanofi agreed to (i) pay Inhibrx stockholders $30 per share of Inhibrx

common stock on closing of the merger (approximately $1.7 billion) and issue one non-transferable contingent value right (CVR)

per share of Inhibrx common stock, entitling its holder to receive a deferred cash payment of $5, contingent upon the

achievement of certain regulatory milestones (approximately $0.3 billion, if those milestones are achieved); (ii) pay off Inhibrx’s

outstanding third-party debt (approximately $0.2 billion); and (iii) contribute capital to a new publicly traded company (New

Inhibrx) (at least $0.2 billion). Since the closing of the merger, Inhibrx has become a wholly owned subsidiary of Sanofi.

Additionally, Sanofi retains a minority stake (approximately 8%) in New Inhibrx.

On October 21, 2024, Sanofi and CD&R entered into exclusive negotiations for the Opella Transaction, as defined under "—

B.3. Opella," which led to the loss of control previously exercised by Sanofi over Opella and triggered Opella's reclassification as a

discontinued operation under IFRS 5 for the 2024 financial year. As a result, Opella’s post-tax profit or loss was presented

B. Business overview

Sanofi’s activities are organized around the following categories within the Biopharma operating segment : Immunology, Rare

Diseases, Neurology, Oncology, Other Medicines and Vaccines.

B.1. Strategy

The market context for Sanofi

Several fundamental trends continue to point to a positive outlook for the pharmaceutical industry. The global population is

growing and ageing, and unmet medical needs remain high. Health needs have further increased, strengthening the key roles of

innovation in R&D activities and cutting-edge manufacturing. The industry has taken steps to increase R&D productivity, with the

objective of launching a higher number of innovative medicines and vaccines. Patients around the world – including a rising

middle class in emerging markets – are demanding better healthcare, empowered by access to more and more information. It is a

challenging time scientifically and technologically: the promise of artificial intelligence (AI) is generating new insights into how to

diagnose and treat diseases, and Immunology remains a key therapeutic area with high unmet needs. Digital technologies and

advanced data analytics are having a transformative effect across sales and marketing activities, R&D and manufacturing, and

are acting as enablers for new businesses.

At the same time, increased geopolitical uncertainties, inflation, supply shortages, and issues around government budget

tightening are expected to continue to put pressure on healthcare costs, and on the entire healthcare value chain. Although we

believe that pharmaceuticals and vaccines will remain a fundamentally attractive business within that value chain, the bar for

innovation will most likely continue to rise. Payers will continue to put scrutiny on prices and reimbursement criteria, and demand

demonstration of real-life outcomes to confirm the efficacy of medicines and vaccines. This will be coupled with more innovative

pricing and contracting practices, and more transparent pricing policies. In view of growing concerns over increasing healthcare

costs across global markets, the pharmaceutical industry will be increasingly judged by its contribution to improved access for

patients and to the development of innovative, highly cost-effective medicines.

Strategic framework

Further, faster for patients

We are an R&D driven, AI-powered biopharma company committed to improving people’s lives and creating compelling growth.

We apply our deep understanding of the immune system to invent medicines and vaccines that positively impact millions of

(1) In partnership with Regeneron.

SANOFI FORM 20-F 2025 19

PART I
ITEM 4. Information on the Company

patients suffering from dermatological, respiratory, gastroenterological, and other immune-mediated diseases. And we are

pioneering an innovative pipeline that could benefit millions more.

We are on a mission to go further, faster for patients. We seek to take the lead through breakthrough science and by leveraging

our broad set of technology and manufacturing platforms, including mRNA.

Advancing Breakthrough Science

We are working to strengthen our pipeline with a steady stream of potentially transformative therapies that could shift paradigms

in treatment and prevention for people across the world.

We have a powerful toolbox of drug discovery platforms that allow us to break scientific ground in five therapeutic areas:

Immunology and Inflammation, Oncology, Rare diseases , Neurology and Vaccines.

Advancing Sustainability

Our ambition is to tackle the impact of environmental challenges on health and healthcare. We do this by focusing on three

dimensions: improving equitable and sustainable access to healthcare, reducing the environmental impact of our activities, and

helping transform the delivery of care to minimize the environmental footprint of healthcare systems. Further, we work actively to

embed sustainability in everything we do across the business.

This builds on our “Play to Win” strategy, organized around four key priorities: 1) focus on growth; 2) lead with innovation;

3) accelerate efficiency; and 4) reinvent how we work to drive innovation and growth.

1) Focus on growth

• Dupixent (dupilumab) (1) – By leveraging the product’s unique mechanism of action targeting the type 2 inflammation pathway

and its favorable safety profile, we have raised our ambition for peak sales of Dupixent. In 2025, Dupixent received approval in

the US in bullous pemphigoid (BP), as well as US and EU approval in chronic spontaneous urticaria (CSU) .

• Launches – in 2025 Sanofi successfully launched Wayrilz in immune thrombocytopenia, Qfitalia in hemophilia A or B with or

without inhibitors, and Nuvaxovid for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe

acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

• Vaccines – Sanofi has been focusing on four core franchises: Influenza and COVID-19; Meningitis, Travel and Endemics; Polio,

Pertussis and Hib (PPH) & Boosters; and RSV.

• Pipeline – We are focusing our investments on projects in immunology and Inflammation, Oncology, Rare diseases, Neurology

and Vaccines.

2) Lead with innovation

We have been able to shift from a priority medicine list to a steady flow of medicines in a refocused, consistent pipeline. Our

pipeline is showing potential opportunities for market-leading products.

To continue fueling our promising pipeline and to enhance our position in our core therapeutic areas, we have:

i. entered into a license agreement with ADEL, Inc. for development and commercialization rights for ADEL-Y01, which has

first-in-class potential for Alzheimer's;

ii. acquired Vicebio, adding an early-stage combination vaccine candidate for RSV and HMPV;

iii. entered into a research collaboration agreement with InduPro, Inc. (InduPro or InduProTherapeutics) to collaborate on

preclinical and IND-enabling research activities, as well as the right of first negotiation for InduPro’s bispecific PD-1 agonist

program, currently in preclinical development for the treatment of autoimmune and inflammatory disorders;

iv. entered into a collaboration agreement with EVOQ Therapeutics, Inc. (EVOQ) establishing a partnership that enhances our

immunology portfolio by integrating EVOQ’s cutting-edge Antigen Specific Immunotherapy (ASI) technology, designed to

restore immune tolerance to self-antigens by selectively re-educating the immune system;

v. acquired Vigil to strengthen our early-stage pipeline in neurology with VG-3927, a novel, oral, small-molecule TREM2 agonist

which will be evaluated in a Phase 2 clinical study in patients with Alzheimer’s disease;

vi. entered into a licensing agreement with VisiRNA Therapeutics, Inc. for the exclusive development and commercialization

rights of p lozasiran in the territory of Greater China;

vii. acquired Blueprint, adding a rare immunology disease medicine, Ayvakit/Ayvakyt (avapritinib), approved in the US and EU and

the only approved medicine for advanced and indolent systemic mastocytosis (ASM & ISM);

viii. entered into a licensing agreement with Libertas Bio, Inc. (a subsidiary of Formation Bio) providing access to Gusacitinib, a

dual JAK/SYK inhibitor, with the intention of exploring its potential as a second line treatment in chronic graft-versus-host

disease (cGVHD) and potentially later in newly diagnosed cGvHD as a steroid free option;

ix. acquired DR-0201, a targeted bispecific myeloid cell engager, from Dren Bio, Inc., to broaden our immunology pipeline and;

x. entered into an agreement to acquire Dynavax Technologies Corporation (Dynavax), a publicly traded vaccines company

with a marketed adult hepatitis B vaccine (HEPLISAV-B) and a differentiated shingles vaccine candidate.

3) Accelerate efficiency

We continue to improve our cost structure, launching efficiency initiatives across our Biopharma business to free operational

resources to support R&D investment and unlock value-creation opportunities. This includes prioritizing our investments in R&D

and modernizing our approach to commercial delivery.

To transform the practice of medicine, we are developing and deploying AI-powered solutions across all business units at all

levels of Sanofi, not only to increase automation and efficiency, but also to fundamentally change the way we work and think. We

are investing in computational tools and AI to develop a comprehensive digital healthcare platform for employees, patients and

providers. AI and data science are already supporting our teams in areas such as accelerating drug discovery, improving clinical

trial design, and streamlining the manufacture and supply of drugs and vaccines. We are driving a company-wide culture shift

that embeds digital DNA into the fabric of our organization.

Our R&D teams are already accelerating their work: our Target Discovery engines have delivered seven novel drug targets in just

one year. Our Manufacturing & Supply (M&S) teams use our AI-powered yield analytics platform, which assesses data trends from

past batches, recommends production parameter adjustments and optimizes raw material use to deliver consistently higher

yields. Across the value chain — from demand planning to quality assurance (QA) — AI-driven automation is being deployed to

boost productivity and agility. AI tools like the Inventory Optimizer, Launch Agent, and Quality Agent are being used to enable

faster, smarter decisions, from allocating production batches, to de-bottlenecking QA workflows, to optimizing launch plans for

success. Our Portfolio Strategy teams are using our enterprise AI layer, Plai, for predictions and strategic recommendations to

make the right decisions about our treatments to maximize patient impact.

In recent years, we have achieved key AI milestones across the business:

• in partnership with Aily Labs GmbH, we deployed the internal application Plai. Plai aggregates internal data across all functions

and harnesses the power of AI to provide timely insights and personalized “what if” development scenarios to support

informed decision-making. Today, over 22,000 of our employees use Plai for day-to-day decision making;

• the expansion of our accelerators continued with the official announcement of our Digital Manufacturing & Supply (M&S)

Accelerator, and talent growth in both our R&D and M&S accelerators;

• in research, we have built multiple AI programs seeking to reduce research lead-times through improved predictive modelling

and automated time-sink activities, enabling our R&D teams to scale and accelerate research processes. Initial results suggest

potential improvements in target identification efficiency in therapeutic areas like immunology, oncology and neurology,

though actual results may vary and are subject to ongoing validation;

• in Manufacturing & Supply, we have developed an in-house AI-enabled yield optimization solution called SimpLY, which learns

from past and current batch performance in an effort to enable consistently higher yield levels. This optimizes usage of raw

materials, supports our environmental efforts, and enhances our cost efficiency. At our sites in France and Singapore, SimpLY

analyzed over 13,000 batch runs of our anticoagulant (Lovenox/Clexane), enabling process optimizations that we estimate to

have generated approximately €10 million in annual cost savings based on our internal analysis of batch performance

improvements at these sites. Actual savings may vary and are subject to ongoing operational factors;

• we have partnered with FormationBio and OpenAI to develop AI-powered software to accelerate drug development, create

custom drug development lifecycle solutions and bring new medicines to patients more efficiently: these AI-powered digital

products rely on advanced AI models to create rich, multidimensional patient profiles, pinpoint outreach channels, and

generate IRB-ready, personalized content – nearly instantly and at scale;

• in 2025, we held a Digital Month that engaged over 20,000 of our employees worldwide, with the aim of continuing to

empower and inform people across our organization and drive adoption of our Digital and AI tools;

• Sanofi's internal GenAI tools are maturing rapidly: Concierge (launched in October 2024) provides access to over 20,000 data

points, supports over 30,000 users and has enabled two hours weekly saved on average per user; and

• approximately 7,000 of Sanofi employees received training via GenAI courses on SanofiU, our in-house learning platform.

4) Reinvent how we work

Transformation and simplification have started, with the aim of increasing empowerment and accountability. To drive

implementation of our culture built on stronger focus, inclusivity and teamwork, we have streamlined our executive leadership

team around 13 members. The complete Sanofi Executive Committee now includes the three managers who head up our Global

Business Units (Specialty Care, General Medicines, and Vaccines) as well as the heads of each of the following support functions:

Research and Development; Manufacturing & Supply; Finance; People & Culture; Digital; Legal, Business Integrity & Global

Security; Corporate Affairs; and Business Operations.

In 2025, as part of the streamlining of our focus, we announced the closing of the sale to CD&R of a 50.0% controlling stake of

our consumer healthcare business, Opella. We retain a significant shareholding in Opella with a 48.2% stake. Sanofi received total

net cash proceeds of around €10 billion. For more information on the transaction, see "— B.3 Opella."

We introduced an updated sustainability strategy in 2025, focused on the critical nexus between health and the environment.

Our strategic focus recognizes that 70% of our medicine and vaccine portfolio and more than 75% of our pipeline target diseases

are impacted by climate and environmental challenges. The AIR strategy is threefold: Access to healthcare; Impact on the

environment; and Resilient healthcare systems. It aims to:

i. expand access to care for conditions affected by environmental challenges;

SANOFI FORM 20-F 2025 21

PART I
ITEM 4. Information on the Company

ii. reduce the environmental impact of our products and activities, while adapting to environmental changes; and

iii. change the delivery of care through treatments and efforts that reduce the environmental footprint of healthcare systems.

Capital allocation policy

We will continue to pursue our focused and disciplined capital allocation policy. Our priorities in deploying the cash generated

from our operations are, in the following order: (i) investment in organic growth; (ii) business development and merger &

acquisition activities, focusing on bolt-on, value-enhancing opportunities to drive scientific and commercial leadership in core

therapeutic areas; (iii) growing the annual dividend; and (iv) anti-dilutive share buybacks. We also have the potential to raise

capital through asset disposals, including streamlining “tail” brands in our established products business.

B.2. Biopharma segment

The sections below provide additional information on our main medicines. Our intellectual property rights over our biopharma

medicines are material to our operations and are described at “B.6. Patents, Intellectual Property and Other Rights” below. As

indicated in note D.22. to the consolidated financial statements, included at Item 18. of this annual report, we are involved in

significant litigation concerning the patent protection of a number of these medicines. For more information on sales

performance in 2025 , see “Item 5. Operating and Financial Review and Prospects — A. Operating Results.”

Immunology

Dupixent

Dupixent (dupilumab) is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13

(IL-13) pathways and is not an immunosuppressant. Dupilumab is jointly developed by Sanofi and Regeneron

Pharmaceuticals, Inc. (Regeneron) under a global collaboration agreement. To date, dupilumab has been studied across more

than 59 completed studies and 23 ongoing studies, involving more than 12,000 patients with various chronic diseases driven in

part by type 2 inflammation. The dupilumab development program has shown significant clinical benefit and a decrease in type 2

inflammation in Phase 3 studies, establishing that IL-4 and IL-13 are key and central drivers of the type 2 inflammation that plays

a major role in multiple inflammatory diseases such as atopic dermatitis (AD), asthma, chronic rhinosinusitis with nasal polyposis,

eosinophilic esophagitis and prurigo nodularis. Dupixent comes in either a pre-filled syringe for use in a clinic or at home by

self-administration as a subcutaneous injection or in a pre-filled pen for at-home administration, providing patients with a more

convenient option. Dupixent is available in all major markets including the US (since April 2017), most European Union countries

(the first launch was in Germany in December 2017), Japan (since April 2018), and China (since June 2020).

Atopic dermatitis (AD)

Moderate-to-severe AD, a form of eczema and a chronic inflammatory disease, is characterized by rashes that sometimes cover

much of the body and can include intense, persistent itching and skin dryness, cracking, redness, crusting and oozing. 85% to

90% of patients first develop symptoms before five years of age, which can often continue through adulthood.

In 2014, the FDA also granted Dupixent Breakthrough Therapy designation, and after a Priority Review evaluation, it granted

Dupixent marketing authorization in March 2017 for the treatment of adults with moderate-to-severe AD whose disease is not

adequately controlled with topical prescription therapies, or when those therapies are not advisable. In 2016, the FDA granted

Dupixent Breakthrough Therapy designation for adolescent patients aged 12 to 17 years and in March 2019, the FDA extended the

marketing authorization to cover this age group.

In 2016, the FDA granted Breakthrough Therapy designation for Dupixent for the treatment of severe AD in children aged

six months to 11 years. On May 26, 2020, Dupixent was approved as the first biologic medicine for children aged 6 to 11 years with

moderate-to-severe AD. Having accepted Dupixent for Priority Review in February 2022, the FDA approved Dupixent on June 7,

2022 for children aged six months to five years with moderate-to-severe AD whose disease is not adequately controlled with

topical prescription therapies or when those therapies are not advisable, making Dupixent the first biologic medicine to

significantly reduce signs and symptoms in children as young as six months.

The EC approved Dupixent in September 2017 for use in adults with moderate-to-severe AD who are candidates for systemic

therapy, and extended the marketing authorization in August 2019 to include adolescents aged 12 to 17 years. On November 30,

2020, the EC extended the marketing authorization to children aged 6 to 11 years with severe AD and on June 28, 2021, the

Dupixent label was updated with long-term data for up to three years, reinforcing the medicine’s well-established safety profile in

adults with moderate-to-severe AD. On January 27, 2023 the Committee for Medicinal Products for Human Use (CHMP) adopted

a positive opinion for Dupixent, recommending expanded approval in the EU to treat severe AD in children aged six months to

five years who are candidates for systemic therapy. In March 2023, Dupixent was approved by the EC as the first and only

targeted medicine for children as young as six months old with severe AD.

On January 22, 2018, the Ministry of Health, Labor and Welfare (MHLW) in Japan granted marketing and manufacturing

authorization for Dupixent for the treatment of AD in adults not adequately controlled with existing therapies. More recently, on

September 25, 2023 Dupixent was approved in Japan to treat patients aged six months and older with moderate-to-severe AD.

On June 19, 2020, the National Medical Products Administration (NMPA) in China approved Dupixent for adults for the treatment

of moderate-to-severe AD after identifying dupilumab as an overseas medicine regarded as urgently needed in clinical practice,

leading to an expedited review and approval process.

ITEM 4. Information on the Company

In April 2023, new abstract data from a long-term efficacy open-label study presented at the Revolutionizing Atopic Dermatitis

(RAD) 2023 Spring Conference in Washington, DC showed that Dupixent demonstrated robust and sustained efficacy with

progressive improvement of AD signs and symptoms in patients with moderate-to-severe AD who completed up to five years of

treatment: the longest duration of data for any biologic medicine in this disease. Additionally, the long-term safety data from a

52-week open-label extension study in children aged six months to five years reinforced the well-established safety profile of

Dupixent observed across all other approved age groups. These data build on the existing evidence supporting the selective way

Dupixent inhibits IL4/IL-13 pathways, both key and central drivers of type 2 inflammation, thereby significantly improving

itching and skin lesions and other important measures that impact a patient’s quality of life. The inclusion of the results from the

five-year OLE study for adults in the Dupixent label was approved in Europe in June 2023, and in the US by the FDA in

October 2023.

In March 2023, positive results from the clinical study assessing Dupixent in adults and adolescents with uncontrolled

moderate-to-severe atopic hand and foot dermatitis were presented in a late-breaking session, one of more than 20 Dupixent

scientific presentations, at the American Academy of Dermatology (AAD) 2023 Annual Meeting. The study, evaluating a biologic

for this difficult-to-treat population, met its primary and key secondary endpoints. In August 2023, the clinical section of the

Dupixent label in Europe was updated to include the hand and foot dermatitis population. In January 2024, the Dupixent US

label was updated with data further supporting use in AD with moderate-to-severe hand and foot involvement.

These Phase 3 data are from the first and only study evaluating a biologic specifically for this difficult-to-treat population and

have also been added to the Dupixent label in the European Union , with regulatory submissions under way in additional

countries.

Asthma

Dupixent was granted marketing authorization by the FDA in October 2018 as an add-on maintenance therapy in patients with

moderate-to-severe asthma aged 12 years and older with an eosinophilic phenotype or with oral corticosteroid-dependent

asthma. In May 2019, the EC approved Dupixent for use as an add-on maintenance treatment in severe asthma patients aged

12 years and older with type 2 inflammation whose symptoms are inadequately reduced by other treatments.

In September 2020, new long-term data from a Phase 3 open-label extension study showed sustained improvement in lung

function and reduction in severe exacerbations in adults and adolescents with moderate-to-severe asthma. On May 17, 2021,

detailed results from a Phase 3 study showed Dupixent significantly reduced severe asthma attacks, and within two weeks rapidly

improved lung function in children aged six to 11 years with uncontrolled moderate-to-severe asthma with evidence of type 2

inflammation. Moreover, Dupixent significantly improved overall asthma symptom control and reduced an airway biomarker of

type 2 inflammation, called fractional exhaled nitric oxide (FeNO), that plays a major role in asthma.

In October 2021, the FDA approved Dupixent as an add-on maintenance treatment for patients aged six to 11 years with

moderate-to-severe asthma characterized by an eosinophilic phenotype or with oral corticosteroid-dependent asthma, thereby

bringing a new treatment for children who may be suffering from life-threatening asthma attacks and poor lung function

affecting their ability to breathe, which could potentially continue into adulthood. On April 7, 2022, the EC approved Dupixent for

use in children aged six to 11 years as an add-on maintenance treatment for severe asthma with type 2 inflammation

characterized by raised blood eosinophils and/or raised FeNO, whose symptoms are inadequately reduced with medium to high

dose inhaled corticosteroids (ICS) plus another medicine for maintenance treatment.

In March 2019, Dupixent was approved in Japan for treating patients aged 12 years and over with severe or refractory asthma

whose symptoms are inadequately controlled with existing therapies.

In addition, in December 2025, Japan granted marketing and manufacturing authorization for Dupixent for the treatment of

bronchial asthma in children aged 6 to 11 years with severe or refractory disease whose symptoms are inadequately controlled

with existing therapy.

In November 2023, Dupixent received approval in China for treatment of moderate to severe asthma patients aged 12 years and

over with type 2 inflammation.

In February 2024, topline results from the VESTIGE Phase 4 clinical study were presented at the 2024 American Academy of

Allergy, Asthma, and Immunology Annual Meeting. This study evaluated the effects of Dupixent on airway remodeling in adults

with uncontrolled moderate-to-severe asthma characterized by an eosinophilic phenotype or those dependent on oral

corticosteroids.

In 2024, Sanofi initiated a Phase 3 study for children aged two to six years suffering from asthma. This parallel, two-arm Phase 3

study aims to evaluate the efficacy and long-term safety of dupilumab treatment in children with uncontrolled asthma and/or

recurrent severe asthmatic wheeze.

Chronic rhinosinusitis with nasal polyposis (CRSwNP)

CRSwNP is a chronic disease of the upper airway that obstructs the sinuses and nasal passages. It can lead to breathing

difficulties, nasal congestion and discharge, reduced or loss of sense of smell and taste, and facial pressure.

In June 2019, the FDA approved Dupixent for use with other medicines to treat CRSwNP in adults whose disease is not controlled.

In October 2019, the EC approved Dupixent for use as an add-on therapy with intranasal corticosteroids in adults with severe

CRSwNP for whom therapy with systemic corticosteroids and/or surgery do not provide adequate disease control. In

March 2020, the Japanese Pharmaceuticals and Medical Devices Agency approved Dupixent as add-on maintenance treatment

for adults with inadequately controlled CRSwNP.

SANOFI FORM 20-F 2025 23

PART I
ITEM 4. Information on the Company

In September 2024, the FDA approved Dupixent as an add-on maintenance treatment for adolescent patients aged 12 to 17 years

with inadequately controlled CRSwNP, expanding the initial FDA approval in CRSwNP from June 2019 for patients aged 18 years

and older. The FDA evaluated Dupixent for this expanded indication under Priority Review, which is reserved for medicines that

represent potentially significant improvements in efficacy or safety in treating serious conditions.

Eosinophilic esophagitis (EoE)

EoE is a chronic and progressive inflammatory disease that damages the esophagus and prevents it from working properly;

swallowing even small amounts of food can be a painful and worrisome choking experience. In severe cases, a feeding tube may

be the only option to ensure proper calorific intake and adequate nutrition. As the disease progresses, patients may continue to

experience symptoms despite multiple treatments.

On September 14, 2020, the FDA granted Breakthrough Therapy designation to Dupixent for the treatment of patients aged

12 years and older with EoE, and subsequently accepted the file for Priority Review on April 4, 2022. On May 20, 2022, the FDA

approved Dupixent to treat patients with EoE aged 12 years and older. With this approval, Dupixent became the first and only

medicine specifically indicated to treat EoE in the US.

On December 16, 2022, the European Medicines Agency (EMA)'s CHMP adopted a positive opinion, recommending the approval

of dupilumab in the EU to treat adults and adolescents with EoE. On January 30, 2023, the EC expanded the marketing

authorization for Dupixent in the EU to include the treatment of EoE in adults and adolescents aged 12 years and older.

On July 14, 2022, a Dupixent Phase 3 study showed positive results in children aged one to 11 years with EoE, making this the fifth

pediatric pivotal study across three type 2 inflammatory diseases to reinforce the well-established efficacy and safety profile of

Dupixent. In January 2024, Dupixent was approved by the FDA for the treatment of adult and pediatric patients aged one year or

older, weighting at least 15 kilograms, with EoE. The EoE pediatric indication was approved in the EU in November 2024.

Prurigo nodularis (PN)

Prurigo nodularis is a chronic, debilitating skin disease with underlying type 2 inflammation and has one of the highest impacts on

a patient’s quality of life among inflammatory skin diseases due to the extreme itching it causes. People with PN experience

intense, persistent itching, with thick skin lesions (called nodules) that can cover most of the body. The disease is often painful –

with burning, stinging and tingling of the skin – and can negatively affect mental health, daily living activities and social

interactions. High-potency topical steroids are commonly prescribed but are associated with safety risks if used long-term.

The FDA evaluated the Dupixent application for PN under Priority Review on May 31, 2022. On September 29, 2022, the FDA

approved Dupixent for the treatment of adult patients with PN. With this approval, Dupixent became the first and only medicine

specifically indicated to treat PN in the US. The FDA approval was based on data from two Phase 3 studies evaluating the efficacy

and safety of Dupixent in adults with PN. Efficacy in these studies assessed the proportion of subjects with clinically meaningful

reduction in itching, clearing of skin, or both. On December 15, 2022, the EC expanded the marketing authorization for Dupixent

in the EU to treat adults with moderate-to-severe PN who are candidates for systemic therapy, after the previous positive

recommendation on November 11, 2022.

The Dupixent PN indication was approved in Japan on June 26, 2023, and in China on September 22, 2023.

Chronic spontaneous urticaria (CSU)

CSU is a chronic inflammatory skin disease characterized by the sudden onset of hives on the skin and/or swelling deep under

the skin. Despite standard-of-care treatment, people with CSU often experience symptoms including a persistent itching or

burning sensation, which can be debilitating and significantly impact quality of life. Swelling often occurs on the face, hands and

feet, but can also affect the throat and upper airways.

On July 29, 2021 a pivotal Phase 3 study evaluating Dupixent in patients with moderate-to-severe CSU met its primary

endpoints and all key secondary endpoints at 24 weeks. Adding Dupixent to standard-of-care antihistamines significantly

reduced itching and hives for biologic-naive pa tients, compared to those treated with antihistamines alone (placebo) in Study A

(the first of three studies) of the LIBERTY CUPID clinical program.

Study B evaluated Dupixent in adults and adolescents who remain symptomatic despite standard-of-care antihistamine

treatment and are intolerant or incomplete responders to an anti-IgE therapeutic (omalizumab). Although positive numerical

trends in reducing itching and hives were observed, t he study met futility criteria in the pre-specified interim analysis. Further

analysis following blinded completion of the study demonstrated that Dupixent met the EU primary endpoin t (UAS7 at week 24).

Th e safety data were generally consistent with the known safety profile of Dupixent in its approved indications. In

December 2022, Dupixent was submitted to the FDA for the CSU indication. In October 2023, the FDA issued a Complete

Response Letter (CRL) stating that additional efficacy data were required to support approval; it did not identify any issues with

safety or manufacturing. Accordingly, a third clinical study (Study C) was initiated to provide additional efficacy data.

In September 2024, the Dupixent confirmatory Phase 3 study (LIBERTY-CUPID Study C) met the primary and key secondary

endpoints for the investigational treatment of patients with uncontrolled, biologic-naive CSU receiving background therapy with

antihistamines. This positive study confirmed results from Study A, but failed to meet the ex-EU primary endpoint (ISS at week

24). Earlier in 2024, Japan was the first country in the world to approve and launch Dupixent for adult and adolescent CSU

patients based on the results from Study A (February 2024), followed by approvals in the United Arab Emirates (September

2024), Brazil (November 2024), the US (April 2025), and the Kingdom of Saudi Arabia (KSA) (October 2025).

Chronic obstructive pulmonary disease (COPD)

COPD is a progressive respiratory disorder that damages the lungs and reduces lung function, making it the fourth leading cause

of death worldwide. Key symptoms include persistent coughing, excessive mucus production, and shortness of breath, which can

significantly affect daily activities and contribute to sleep disturbances, anxiety, and depression. COPD also imposes a major

health and economic burden due to frequent acute exacerbations, often requiring treatment with systemic corticosteroids

and/or antibiotics, and hospitalizations when severe. Exacerbations are also associated with lung function decline and worsened

clinical burden and outcomes in a vicious cycle. While smoking and exposure to harmful particles are primary risk factors, the

disease may still progress in those who have quit smoking.

Around 50% of COPD patients continue to experience exacerbations despite receiving triple inhaled therapy. In the US,

approximately 300,000 individuals have inadequately controlled COPD with Type 2 Inflammation (also known as eosinophilic

phenotype), a subgroup prone to a 30% increase in exacerbations and a higher risk of COPD-related hospital readmissions within

a year.

On July 3, 2024, following a positive review by the EMA, the EC approved Dupixent as an add-on maintenance treatment for

adults with uncontrolled COPD characterized by elevated blood eosinophils. This approval covers patients already on a

combination of an inhaled corticosteroid (ICS), a long-acting beta2-agonist (LABA), and a long-acting muscarinic antagonist

(LAMA), or those on a LABA /LAMA combination if ICS is unsuitable. The EC was the first regulatory agency worldwide to grant

approval for Dupixent in COPD patients.

On September 10, 2024, a pooled analysis from the BOREAS and NOTUS Phase 3 studies showed that Dupixent reduced

exacerbations and improved lung function and quality of life compared to placebo in adults with uncontrolled COPD and

evidence of type 2 inflammation (i.e. raised blood eosinophils). The results were presented for the first time, in collaboration with

Regeneron, at the 2024 European Respiratory Society (ERS) International Congress.

On September 27, 2024, the NMPA in China also approved Dupixent as an add-on treatment for adults with uncontrolled COPD

and raised blood eosinophils. This approval similarly covers patients on combinations of ICS, LABA, and LAMA, or LABA and LAMA

if ICS is not appropriate. Dupixent has now been approved for the treatment of COPD in over 30 countries, including the 27 EU

member states.

On September 27, 2024, the FDA approved Dupixent as the first biologic treatment for COPD in the US. This approval, which

applies to adults with inadequately controlled COPD and an eosinophilic phenotype, was based on two pivotal Phase 3 studies

showing significant reductions in exacerbations and improvements in lung function and quality of life compared to placebo.

Dupixent has become the leading biologic in new-to-brand prescriptions across all its FDA-approved indications and is the most

prescribed biologic by US pulmonologists.

As of October 2025, Dupixent had been approved for COPD in 53 countries and launched across 17 markets including the US,

Germany, China and Japan.

Bullous pemphigoid (BP)

BP is a chronic, debilitating and relapsing skin disease. It affects approximately 52,000 adults in the US, and is characterized by

intense itch and blisters, reddening of the skin and painful lesions. It can be chronic and relapsing with underlying type 2

inflammation, and primarily affects elderly patients. The blisters and rash can form over much of the body and cause the skin to

bleed and crust, resulting in patients being more prone to infection and affecting their daily functioning. Available treatment

options are limited and can add to overall disease burden by suppressing a patient’s immune system.

In June 2025, Dupixent (dupilumab) was approved in the US as the only targeted medicine to treat patients with BP. The FDA

approval was based on data from the pivotal Phase 2/3 ADEPT trial that evaluated the efficacy and safety of Dupixent compared

to placebo in adults with moderate-to-severe BP.

ADEPT was a randomized, Phase 2/3, double-blind, placebo-controlled trial evaluating the efficacy and safety of Dupixent in 106

adults with moderate-to-severe BP for a 52-week treatment period. After randomization, patients received Dupixent or placebo

every two weeks after an initial loading dose, along with oral corticosteroids (OCS) treatment. During treatment, OCS taper was

initiated after patients experienced two weeks of sustained control of disease activity. OCS tapering could start between four to

six weeks after randomization and was continued if disease control was maintained, with the intent of completion by 16 weeks.

After OCS tapering, patients were only treated with Dupixent or placebo for at least 20 weeks, unless rescue treatment was

required.

The primary endpoint evaluated the proportion of patients achieving sustained disease remission at 36 weeks. Sustained disease

remission was defined as complete clinical remission with completion of OCS taper by 16 weeks without relapse after completion

of the OCS taper and no rescue therapy use during the 36-week treatment period. Relapse was defined as the appearance of

three or more new lesions a month, or at least one large lesion or urticarial plaque (greater than 10 cm in diameter), that did not

heal within a week. Rescue therapy could include treatment with high-potency topical corticosteroids, OCS (including increase of

OCS dose during the taper or re-initiation of OCS after completion of the OCS taper), systemic non-steroidal immunosuppressive

medications or immunomodulating biologics.

Kevzara

Kevzara (sarilumab) is a human monoclonal antibody that binds to the interleukin-6 receptor (IL-6R) and has been shown to

inhibit IL-6R mediated signaling.

IL-6 is a multi-functional cytokine that acts as a critical signaling node in the complex pro-inflammatory cytokine network that

underpins rheumatoid arthritis (RA), Polymyalgia rheumatica (PMR) and other immune-mediated diseases. Kevzara has been

approved for RA in 39 countries. For the PMR indication, Kevzara has been approved in the US, EU, UK, Canada, and Israel. In

2024, the FDA approved Kevzara for the treatment of active polyarticular juvenile idiopathic arthritis (pJIA) , followed by the EU

and UK in 2025.

Kevzara is developed and commercialized in collaboration with Regeneron. For additional information, see “Item 5. Operating and

Financial Review and Prospects — A.1.7. Financial Presentation of Alliances — Alliance Arrangements with Regeneron

Pharmaceuticals, Inc. (Regeneron).”

Rheumatoid arthritis (RA)

RA is a chronic inflammatory autoimmune disease causing inflammation, pain, and eventually joint damage and disability. Kevzara

is approved in 39 countries for use in combination with disease modifying anti-rheumatic drugs (DMARDs) or as monotherapy for

the treatment of moderately to severely active RA in adult patients who respond inadequately or are intolerant to DMARDs or

tumour necrosis factor ( TNF) antagonist.

In May 2017, the FDA approved Kevzara for the treatment of adult patients with moderately to severely active RA who have

responded inadequately to, or who are intolerant to one or more DMARDs .

In June 2017, the EC granted marketing authorization for Kevzara in combination with methotrexate for the treatment of

moderately to severely active RA in adult patients who have responded inadequately to – or who are intolerant to – one or more

DMARDs. Kevzara can be given as monotherapy in case of intolerance to methotrexate or when treatment with methotrexate is

inappropriate.

In September 2017, Kevzara obtained manufacturing and marketing approval in Japan as a treatment for RA not responding well

to conventional treatments.

Polymyalgia rheumatica (PMR)

PMR is a rheumatic inflammatory disorder characterized by pain and stiffness around the neck, shoulder and hip areas that leads

to significant decline in quality of life. Kevzara is approved for the treatment of adult patients with PMR in the US, Israel, EU, UK

and Canada.

In February 2023, the FDA approved Kevzara for the treatment of adult patients with PMR who have had an inadequate response

to corticosteroids or who cannot tolerate a corticosteroid taper.

In November 2024, the EC granted marketing authorization for Kevzara for the treatment of PMR in adult patients who have had

an inadequate response to corticosteroids, or who experience a relapse on a corticosteroid taper.

Polyarticular Juvenile Idiopathic Arthritis（pJIA）

Juvenile idiopathic arthritis (JIA) is an umbrella-term describing a heterogeneous group of conditions characterized by chronic

arthritis beginning before the age of 16 years, persisting for at least 6 weeks, and having no other identifiable cause. Polyarticular

JIA includes a blend of patients with a wide spectrum of etiologic risk factors, unique disease course, and therapeutic challenges.

In June 2024, the FDA approved Kevzara for treatment of active pJIA in patients who weigh 63 kilograms or more.

In January 2025, the EC granted marketing authorization for Kevzara for the treatment of active pJIA in patients aged two years

and older. Kevzara is indicated for those who have not responded adequately to previous therapies with conventional synthetic

DMARDs. Kevzara may be used as monotherapy or in combination with methotrexate. The treatment is administered as an

injection under the skin once every two weeks, and is effective in reducing inflammation and improving symptoms associated

with pJIA.

Rare diseases

Cerezyme

Cerezyme (imiglucerase) is an enzyme replacement therapy (ERT) used to treat Gaucher disease, a chronic, inherited, progressive

and potentially life-threatening lysossomal storage disorder (LSD). Gaucher disease is caused by a deficiency of the enzyme

glucocerebrosidase; this causes a fatty substance called glucosylceramide (also called GL-1) to build up in certain areas of the

body including the spleen, liver, and bone. Gaucher disease exhibits diverse manifestations, a broad range of onset of symptoms,

and a wide clinical spectrum of disease severity. It is estimated that Gaucher disease occurs in approximately one in

120,000 newborns in the general population and one in 850 in the Ashkenazi Jewish population worldwide, but incidence and

patient severity vary among regions. Cerezyme has been marketed in the US since 1994, in the EU since 1997, in Japan since 1998

and in China since 2008, and is approved to treat type 1 Gaucher disease in more than 85 countries. It has also been approved to

treat the systemic symptoms of type 3 Gaucher disease in most non-US markets, including the EU and Japan.

Cerdelga

Cerdelga (eliglustat) is the first and only first-line oral therapy for Gaucher disease type 1 adult patients. A potent, highly specific

ceramide analog inhibitor of GL-1 synthesis with broad tissue distribution, Cerdelga has demonstrated efficacy in the treatment

of naive Gaucher disease patients and in patients who switch from enzyme replacement therapy. Cerdelga has been approved to

treat type 1 Gaucher disease in the US (2014), and in the EU and Japan (2015). It is also in development for the treatment of type 1

Gaucher disease in pediatric patients. See “— B.4. Global Research & Development.”

Myozyme and Lumizyme

Myozyme (alglucosidase alfa) is an ERT used to treat both Infantile Onset and Late Onset Pompe disease (IOPD and LOPD).

Pompe disease is an inherited, progressive and often fatal neuromuscular disease, caused by a genetic deficiency or dysfunction

of the lysosomal enzyme acid alpha-glucosidase (GAA) that results in the build-up of glycogen in the muscles’ cells. For IOPD,

symptoms begin within a few months of birth and there are impacts on the heart in addition to causing skeletal muscle weakness.

Other symptoms include difficulties breathing, frequent chest infections, problems feeding that result in failure to gain weight as

expected, and failure to meet certain developmental milestones. Patients with LOPD typically present symptoms any time after

the first year of life to late adulthood and rarely manifest cardiac problems. The hallmark symptom of LOPD is skeletal muscle

weakness, which often leads to walking disability and reduced respiratory function. Patients often require wheelchairs to assist

with mobility and may require mechanical ventilation to help with breathing. Pompe disease occurs in approximately one in

40,000 newborns worldwide, but incidence and patient severity vary among regions.

Myozyme was first approved in 2006 in the EU and has since been approved in more than 80 countries. In the US, alglucosidase

alfa has been marketed as Lumizyme since 2010.

Nexviazyme/Nexviadyme

Nexviazyme/Nexviadyme (avalglucosidase alfa-ngpt) is a novel mannose-6-phosphate (M6P) enriched ERT treatment designed

as a monotherapy for the entire spectrum of infantile-onset and late-onset Pompe disease (IOPD, LOPD), including patients who

have changed treatments and naive patients, who have not received treatment previously. Nexviazyme/Nexviadyme is

scientifically designed to specifically target the M6P receptor, the key pathway for ERT, to effectively clear glycogen build-up in

muscle cells. It helps replace the GAA enzyme for people whose bodies do not produce enough. Investment in the clinical

development of Nexviazyme is continuing, with an ongoing Phase 3 study in treatment-naive IOPD patients aged less than

12 months. Nexviazyme/Nexviadyme is administered as a monotherapy every two weeks.

Nexviazyme was first approved in the US by the FDA on August 6, 2021 for LOPD patients aged one year and older. On June 24,

2022, the EC granted marketing authorization for Nexviadyme as a potential new standard of care for the long-term treatment of

both LOPD and IOPD. Nexviazyme/Nexviadyme has been approved in more than 59 countries and successfully launched in

32 countries including the US, Germany, the UK, other European markets, Japan and Australia. In all launched markets, the vast

majority of eligible patients are currently being treated with Nexviazyme/Nexviadyme.

Fabrazyme

Fabrazyme (agalsidase beta) is an ERT used to treat Fabry disease (FD). FD is a multisystemic, progressive, X-linked inherited

disorder of glycosphingolipid metabolism due to deficient or absent lysosomal α-galactosidase A activity resulting in progressive

globotriaosylceramide (GL-3) accumulation in the lysosomes of various tissues. FD affects both genders. With age, progressive

organ damage develops, leading to potentially life-threatening renal, cardiac and/or cerebrovascular complications. FD is

characterized by different symptom severities and rates of progression, ranging from classic disease with early symptom onset to

non-classic disease with cardiac and/or renal complications later in life. FD is seen in all racial and ethnic groups and is an

under-diagnosed condition. Prevalence estimates vary across regions. Classic FD mutations are estimated to be approximately

1:40,000 in males with more wide-ranging estimates for non-classic in both males and females. Fabrazyme has been marketed in

the EU since 2001 and in the US since 2003 and is approved in more than 70 countries.

Aldurazyme

Aldurazyme (laronidase) is the only approved ERT for mucopolysaccharidosis type 1 (MPS I), an inherited lysosomal storage

disorder caused by a deficiency of alpha-L-iduronidase, a lysosomal enzyme normally required for the breakdown of certain

complex carbohydrates known as glycosaminoglycans (GAGs). MPS I is multi-systemic, and children with MPS I are described as

having either a severe or attenuated form of the disorder based on age of onset, severity of symptoms, rate of disease

progression and whether there is early and direct involvement of the brain. MPS I occurs in approximately one per 100,000 live

births worldwide, but incidence and patient severity vary among regions. Sanofi markets Aldurazyme in the EU and the US (since

2003) and in more than 75 other countries.

Xenpozyme

Xenpozyme (olipudase alfa) is an ERT designed to replace deficient or defective acid sphingomyelinase (ASMD), an enzyme that

allows for the breakdown of the lipid sphingomyelin. In individuals with ASMD, an insufficiency of the ASM enzyme means

sphingomyelin is poorly metabolized, potentially leading to lifelong accumulation in and damage to multiple organs.

The significance of the unmet need that Xenpozyme addresses has been recognized by Japan’s PMDA with Sakigake designation,

by the EU with PRIME designation, and by the FDA with Breakthrough designation.

Xenpozyme was approved first in Japan on March 28, 2022, followed by Europe on June 24, 2022 and the US on August 31, 2022.

Xenpozyme is the first and only ERT for the treatment of non-central nervous system manifestations of ASMD, with

demonstrated improvements in hepatosplenomegaly, pulmonary, liver and hematologic function, dyslipidemia, and growth

(children only) in clinical studies of adults and children with ASMD. Xenpozyme is given as an intravenous infusion once every two

weeks, and the dose is based on body weight.

Xenpozyme has to date been commercialized in 26 countries, however only 15 of those have full reimbursement by payers. By

2030, it is anticipated that Xenpozyme will have been launched in many additional markets worldwide.

Wayrilz

Wayrilz (rilzabrutinib) is the first oral reversible Bruton’s tyrosine kinase (BTK) inhibitor for immune thrombocytopenia (ITP) that

helps address the root cause of disease through multi-immune modulation. BTK, expressed in B cells, macrophages and other

innate immune cells, plays a critical role in multiple immune-mediated disease processes and inflammatory pathways. With the

application of Sanofi’s TAILORED COVALENCY technology, Wayrilz can selectively inhibit the BTK target while potentially

reducing the risk of off-target side effects.

Wayrilz is being studied across a variety of rare or inflammatory diseases, including warm autoimmune hemolytic anemia (wAIHA),

IgG4-related disease (IgG4-RD), and sickle cell disease (SCD). These additional indications are currently under investigation and

have not been approved by regulatory authorities.

ITP is a disease of complex immune dysregulation that causes low platelet counts (less than 100,000/μL), resulting in a variety of

bleeding symptoms and high risk of thromboembolism. Beyond bruising and bleeding, which can include potentially life-

threatening episodes like intracranial hemorrhage, people living with ITP may experience reduced quality of life, including

physical fatigue and cognitive impairment.

The FDA has approved Wayrilz for adults with persistent or chronic ITP who have had an insufficient response to a previous

treatment. The approval was based on the pivotal LUNA 3 Phase 3 study, in which Wayrilz met the primary and secondary

endpoints, showing a positive impact on sustained platelet counts and other ITP symptoms, like fatigue. Wayrilz has also been

approved in the United Arab Emirates. The EC has approved Wayrilz as a new treatment for ITP in adult patients who are

refractory to other treatments, following a positive opinion from the European Medicines Agency's Committee for Medicinal

Products for Human Use (CHMP). Wayrilz has received Fast Track and Orphan Drug Designations (ODD) from the FDA for ITP,

European Medicines Agency orphan designation in IgG4-RD.

ALTUVIIIO

ALTUVIIIO (Antihemophilic Factor Recombinant, Fc-VWF-XTEN Fusion Protein) is a first-in-class high-sustained factor VIII

therapy that is designed to extend protection from bleeds with once-weekly prophylactic dosing for adults and children with

hemophilia A. Hemophilia A is a rare, x-linked genetic bleeding disorder characterized by a deficiency of functional coagulation

factor VIII, resulting in a prolonged patient plasma-clotting time. As a consequence, people with hemophilia A bleed for a longer

time than normal.

ALTUVIIIO temporarily replaces the missing coagulation factor VIII by intravenous injection. In adults and adolescents, it is the

first factor VIII therapy that has been shown to break through the von Willebrand factor ceiling, which imposes a half-life

limitation on earlier generation factor VIII therapies. ALTUVIIIO builds on innovative Fc fusion technology by adding a region of

von Willebrand factor and XTEN polypeptides to extend its time in circulation.

ALTUVIIIO was first approved in February 2023 by the FDA, which had previously granted Breakthrough Therapy designation in

May 2022 (the first factor VIII therapy to receive this designation); fast-track designation in February 2021; and Orphan Drug

designation in 2017. ALTUVIIIO has since been approved the by regulatory authorities in Canada, Japan, Taiwan, Macau and Hong

Kong, and has been commercialized in Japan and Taiwan. The European Commission (EC) granted Orphan Drug designation in

June 2019 and a marketing authorization application was filed with the European Medicines Agency (EMA) in May 2023.

ALTUVOCT (the brand name of ALTUVIIIO in Europe) received EC marketing authorization in June 2024.

Qfitlia (f itusiran ) is a first-in-class antithrombin lowering therapy indicated for routine prophylaxis to prevent or reduce the

frequency of bleeding episodes in adult and pediatric patients aged 12 years and older with hemophilia A or B with or without

factor VIII or IX inhibitors. Hemophilia A and B are rare, x-linked genetic bleeding disorders characterized by a deficiency of

functional coagulation factor VIII or IX, respectively, resulting in a prolonged patient plasma-clotting time. Consequently, people

with hemophilia A or B bleed for a longer time than normal.

Qfitlia is a small interfering RNA therapeutic designed to lower antithrombin, a protein that inhibits blood clotting, with the goal of

promoting thrombin generation to rebalance hemostasis and prevent bleeds. Qfitlia utilizes Alnylam Pharmaceutical, Inc.’s

ESC-GalNAc conjugate technology, which enables subcutaneous dosing every other month. It is administered via subcutaneous

injection with a convenient, prefilled pen for the 50 mg dose.

Qfitlia has received approval from the FDA, which had previously granted it Breakthrough Therapy designation, Fast Track

experiencing an episode of acquired thrombotic thrombocytopenic purpura (aTTP). Depending on the country, Cablivi is

approved in adults only or in adults and pediatric population aged 12 years and above. Cablivi is the first and a best-in-class

treatment reducing aTTP morbidities and mortality to improve and save lives. Cablivi treatment results in the inhibition of

microthrombi formation and preventing organ damage.

Acquired thrombotic thrombocytopenic purpura is an ultra-rare (3.5-4.5 episodes per million of population), life-threatening,

autoimmune-based blood clotting disorder characterized by extensive clot formation in small blood vessels throughout the body,

leading to severe thrombocytopenia (very low platelet count); microangiopathic hemolytic anemia (loss of red blood cells through

destruction); ischemia (restricted blood supply to parts of the body); and widespread organ damage, especially in the brain and

heart.

Cablivi was granted marketing authorization in Europe by the EC in September 2018; in the US by the FDA in February 2019; and in

Japan by the Japanese Pharmaceutical and Medical Devices Agency (PMDA) in September 2022. Cablivi is currently

commercially available in 28 countries including the US, the majority of European countries, Switzerland, Brazil, Colombia, Japan

and five Greater Gulf region states. Recently, Cablivi obtained Regulatory BLA approval in China following priority review .

Ayvakit/Ayvakyt

Ayvakit/Ayvakyt (generic name: avapritinib) is a small-molecule tyrosine kinase inhibitor (TKI) that works by selectively inhibiting

mutant forms of KIT (D816V mutation) and PDGFRA (platelet-derived growth factor receptor alpha; D842V mutation) kinases.

Ayvakit/Ayvakyt has been indicated for treatment of adults with unresectable, metastatic gastrointestinal stromal tumors (GIST),

and with advanced and indolent systemic mastocytosis (SM). The FDA has granted three breakthrough therapy designations to

Ayvakit. The medicine has received orphan drug designations from the FDA and orphan medicinal product designations from the

EMA for the treatment of advanced and indolent systemic mastocytosis and unresectable or metastatic GIST.

Ayvakit was first approved by the FDA in January 2020 for the treatment of adults with unresectable or metastatic GIST

harboring a PDGFRA exon 18 mutation, including PDGFRA D842V mutations. PDGFRA exon 18 mutations, including the PDGFRA

D842V mutation, are primary drivers of disease in a subset of patients with GIST. Ayvakit is the only approved medicine for

patients with PDGFRA D842V-driven GIST. The medicine received EMA conditional marketing authorization as Ayvakyt for the

treatment of adults with unresectable or metastatic GIST harboring a PDGFRA D842V mutation in September 2020.

Ayvakit was FDA approved for the treatment of adults with advanced SM in June 2021 and indolent SM (ISM) in May 2023. The

medicine received EMA approval under the brand name Ayvakyt for the treatment of adults with advanced SM, including

aggressive SM (ASM), SM with an associated hematological neoplasm (SM-AHN) or mast cell leukemia (MCL), after at least one

systemic therapy, and adults with ISM with moderate to severe symptoms inadequately controlled on symptomatic treatment. It

is the only medicine approved across the spectrum of advanced and indolent systemic mastocytosis (SM). For patients with SM,

the KIT D816V mutation leads to uncontrolled proliferation and activation of mast cells, resulting in chronic, severe and often

unpredictable symptoms across multiple organ systems. In addition, advanced SM is associated with organ damage due to mast

cell infiltration and poor survival.

Ayvakit was developed and is marketed by Blueprint Medicines, a Sanofi company. Globally, Ayvakit is approved for one or more

indications in more than 35 countries worldwide, including China where it has been developed and commercialized by CStone

Pharmaceuticals.

antitumor effects through multiple mechanisms of action. It is approved in nearly 60 countries for four indications in both newly

diagnosed (NDMM) and relapsed refractory multiple myeloma (RRMM).

Sarclisa was first approved in the US in March 2020 in combination with pomalidomide and dexamethasone for the treatment of

adults with RRMM who have received at least two prior therapies including lenalidomide and a proteasome inhibitor. In Europe,

the EC granted approval in May 2020 for Sarclisa in combination with pomalidomide and dexamethasone for the treatment of

adult patients with RRMM who have received at least two prior therapies including lenalidomide and a proteasome inhibitor and

have demonstrated disease progression on the last therapy. In early 2025, Sarclisa in combination with pomalidomide and

dexamethasone was approved by the NMPA in China for the treatment of adult patients with MM who have received at least one

prior line including lenalidomide and proteasome inhibitor, representing the first indication of Sarclisa approved in China.

In March 2021, Sarclisa received approval in the US for a label extension in combination with carfilzomib and dexamethasone for

the treatment of adults with RRMM who have received one to three prior lines of therapy. In Europe, the EC approved this

combination in April 2021 for the treatment of adult patients with MM who have received at least one prior therapy. The Japanese

MHLW granted approval for Sarclisa in November 2021 in combination with carfilzomib and dexamethasone, in combination with

dexamethasone, and as monotherapy for RRMM patients.

Vaccines

The Vaccines division of Sanofi is a world leader in the vaccine industry and a key supplier of life-saving vaccines all over the

world and for publicly funded international stakeholders such as UNICEF, the Pan American Health Organization (PAHO) and the

Global Alliance for Vaccines and Immunization (GAVI).

The Vaccines portfolio includes the following products:

Influenza vaccines

Sanofi is a world leader in the production and marketing of influenza vaccines, offering several distinct influenza vaccines that are

sold globally.

As influenza strains can vary from one season to the next, the World Health Organization (WHO) selects the strains to be included

in influenza vaccines for each season. For the 2024 season, the WHO recommended moving from quadrivalent influenza vaccines

including two A strains and two B strains back to trivalent influenza vaccines including two A strains and one B strain, as it was

considered that the B Yamagata strains were no longer circulating. Manufacturers have therefore progressively moved back from

quadrivalent to trivalent influenza vaccines. In 2025, Sanofi switched to trivalent in most geographies.

Fluzone High-Dose, designed specifically to provide greater protection against influenza for people aged 65 years and older, was

approved by the FDA in November 2019 in its quadrivalent formulation. The high-dose vaccine was also approved in the EU in the

second quarter of 2020, under the name Efluelda, indicated for adults aged 60 years and above. Both Fluzone High-Dose and

Efluelda have been available since the 2020/21 influenza season. To date, this vaccine has been distributed to more than

25 countries worldwide. Fluzone High-Dose/Efluelda (trivalent formulation) includes two A strains and only one B strain. In

October 2025, The Lancet published new data from the FLUNITY-HD study showing Fluzone High-Dose significantly reduced

the risk of hospitalization in adults aged 65 years and older compared to standard-dose influenza vaccines. FLUNITY-HD is the

largest influenza vaccine effectiveness study of individually randomized older adults, with nearly half a million participants across

three influenza seasons.

Flublok is a trivalent recombinant protein-based influenza vaccine licensed in the US, Hong Kong and Australia; this same

recombinant protein-based influenza vaccine is also licensed under the brand name Supemtek in the United Kingdom. Flublok is

indicated for individuals aged nine years and older in the US and for adults aged 18 and older in other countries.

Fluzone trivalent is an inactivated trivalent influenza vaccine (TIV), produced in the US, containing two type A antigens and one

type B antigen. Fluzone trivalent is available in five countries (including the US) for children aged over six months, adolescents

and adults.

Vaxigrip is a trivalent influenza vaccine, containing two antigens against type A influenza viruses and one antigen against type B

influenza viruses.

VaxigripTetra is the quadrivalent (QIV) version of Vaxigrip, including two antigens against A strains of influenza viruses and two

antigens against B strains, and is produced in France. Vaxigrip Tetra was licensed in 2016 and has been approved in more than

90 countries. Following the new WHO recommendations, countries have switched back to Vaxigrip (trivalent) for the coming

seasons.

COVID Vaccine

In 2025, Sanofi started to commercialize the recombinant adjuvanted COVID-19 vaccine Nuvaxovid, developed by Novavax.

Sanofi is now the market authorization holder for this vaccine in the US, the EU and the United Kingdom, leading the

commercialization of Nuvaxovid in the US for the 2025-26 season and expanding to other markets from the 2026-27 season and

beyond .

ACT-HIB is a standalone vaccine protecting against Hib, and is mainly distributed in the US in conjunction with pertussis

combination vaccines that do not contain the Hib valence.

Sanofi is a leading provider of polio vaccines and has been a partner of the Global Polio Eradication Initiative (GPEI) for over

30 years. Since Sanofi launched its first IPV, more than 1.5 billion doses have been distributed worldwide.

Booster vaccines

Adacel is the leading trivalent booster vaccine offering protection against diphtheria, tetanus and pertussis (Tdap) . The vaccine

can be used from four years of age following primary immunization and is the first Tdap vaccine indicated for use during

pregnancy for protection against pertussis in newb orns. It is available in approximately 70 countries including the US and other

countries, mostly in Europe, Asia and Latin America. Recently, Adacel has been introduced in additional countries that are

implementing new vaccination programs, particularly focusing on maternal immunization.

Repevax/Adacel-Polio is a combination vaccine that provides protection against diphtheria, tetanus, pertussis and polio. It is the

first Tdap-IPV vaccine indicated for use during pregnancy for protection against pertussis in newborns. It is currently marketed in

approximately 25 countries outside the US, with a strong focus on Eu ropean markets (such as France and Germany).

Respiratory syncytial virus (RSV) protection

In 2023, Sanofi launched Beyfortus (nirsevimab-alip), a long-acting monoclonal antibody designed to protect all infants against

RSV. It is indicated for the protection of neonates and infants born during or entering their first RSV season, and for children up to

24 months who remain particularly vulnerable to severe RSV in their second RSV season.

Beyfortus is licensed in numerous countries and has now been launched in more than 45 countries, including in North America,

Europe, China and Japan. Real world data from countries such as the US, Spain and France have confirmed and even surpassed

the outstanding efficacy data generated during the clinical development of this monoclonal antibody. Many more countries are

expected to implement all-infant protection programs in the future. Sanofi and AstraZeneca plc (AstraZeneca) entered into an

agreement in 2017 to develop and commercialize Beyfortus, under which AstraZeneca leads development and manufacturing

activities and Sanofi leads commercialization activities and records revenues. Sanofi will continue to expand Beyfortus in new

geographies across Europe, Asia and Latin America.

Meningitis and travel & endemic vaccines

Menactra, the first quadrivalent conjugate vaccine against meningococcal meningitis (serogroups: A, C, Y, and W-135), one of the

deadliest forms of meningitis, is indicated for people aged nine months through 55 years. Since launch, it has become a strong

leader in the meningitis quadrivalent market. It is commercialized in a large number of countries (excluding Europe ). Menactra was

the first fully liquid (no reconstitution needed) meningitis quadrivalent conjugated vaccine, and more than 150 million doses of

this vaccine have been distributed since launch.

MenQuadfi is a novel fully-liquid meningococcal quadrivalent conjugated vaccine expected to have a broad age indication from

infants (six weeks) to the elderly, with flexible dosing schedules. MenQuadfi has demonstrated consistent, long-lasting immune

responses across serogroups A, C, W and Y, with demonstrated superiority for serogroup C in toddlers versus comparators

(standard-of-care in multiple markets in Europe and internationally), while offering a favorable safety profile. Over time,

MenQuadfi will fully replace Menactra. The product is currently approved and available across multiple markets worldwide, with

over 23 million doses distributed since launch. In the US, regulatory approval extends to individuals aged six weeks and above,

following the FDA label extension granted in May 2025.

Sanofi provides a comprehensive portfolio of travel and endemic vaccines, including yellow fever, rabies, typhoid and hepatitis A

vaccines. These vaccines are used by diverse populations, from populations in endemic regions to travelers and military personnel

from non-endemic regions. Those vaccines are the foundation for important partnerships with governments and organizations

such as UNICEF. Sanofi is currently investing in next-generation rabies and yellow fever vaccines to address evolving public

health needs.

Vaxelis

Vaxelis is a hexavalent combination vaccine protecting against diphtheria, tetanus, pertussis, polio, Hib and hepatitis B. This

vaccine (developed and distributed in partnership with Merck & Co., Inc.) was approved in 2016 by the EC and is distributed in

various EU countries either by Sanofi or by MSD. Vaxelis was approved by the FDA in December 2018, becoming the first

hexavalent vaccine to be approved in the US, and launched in that country in June 2021.

Sales of Vaxelis in the US are recognized by the MSP Vaccine Company joint venture and credited equally to Merck & Co., Inc. and

Sanofi as income from equity affiliates. Consequently, these sales are not reported separately in each joint venture partner’s net

sales. Sanofi recognizes 50% of the joint venture's profits within the line item Share of profit/(loss) from investments

accounted for using the equity method .

B.3. Opella

In October 2024, in line with its strategy of focusing on innovative medicines and vaccines, Sanofi announced that it had entered

into exclusive negotiations for the sale of a controlling stake of around 50% in Opella to CD&R. Following those negotiations,

Sanofi sold a 50% controlling stake in Opella to CD&R through a share purchase agreement and a separation agreement, which

are described below.

• Share Purchase Agreement

In connection with the sale of a 50% controlling stake in Opella to CD&R (the Opella Transaction), on February 18, 2025, Sanofi

and Opal Bidco SAS (Bidco) entered into a share purchase agreement (the SPA). Sanofi and Bidco made certain customary

representations and warranties and agreed to certain customary covenants in connection with the SPA and the transaction

closed on April 30, 2025 (the Closing).

At Closing, Sanofi and CD&R (together with certain funds and affiliates) entered into a shareholders’ agreement (the

Shareholders’ Agreement) relating to the associate Opal JV Co S.à R.L. (JV Co), the joint venture holding company that indirectly

owns Opella following Closing. Sanofi retains a significant shareholding in Opella, through a 48.2% equity interest in JV Co.

Bpifrance Participations acquired an approximately 1.8% equity interest in JV Co. at Closing and is represented on Opella’s Board.

The Shareholders’ Agreement provides for a lock-up period of three years from Closing, during which Sanofi is only permitted to

carry out certain types of direct or indirect transfers of its securities in JV Co, and thereafter any transfer by Sanofi is subject to a

right of first offer in favor of CD&R, together with customary tag‑along and drag‑along rights.

• Separation Agreement

In connection with the separation of the Opella business, Sanofi entered into a Separation Agreement and certain other

agreements with Opella on July 22, 2024, to effect the separation of the Opella business and provide a framework for their

ongoing relationship. The Separation Agreement was amended on April 30, 2025.

The Separation Agreement sets out the rights and obligations of the parties with respect to the separation, including the terms

and conditions governing the transfer of assets to, and assumption of liabilities by, each of the Opella group and the Sanofi

group. In particular, Sanofi retained Gold Bond Co LLC and its business, and provided for the allocation of retained assets and

liabilities accordingly.

The Sanofi group and the Opella group each agreed, subject to certain exceptions, to release and indemnify the other party and

each of their respective past, present and future directors, officers, managers, agents and employees and each of the heirs,

executors, administrators, successors and assigns of any of the foregoing from any and all claims against any of them that arise

out of or relate to their respective businesses.

The Sanofi group agreed to indemnify the Opella group in respect of all liabilities relating to Sanofi’s retained businesses

(including environmental liabilities, whether arising before or after the Closing) and specified matters relating to Zantac branded

products prior to Closing, including product liability claims arising from commercialization, and personal injury claims resulting

from the manufacturing or handling of Zantac prior to Closing ( see Note D.22.a. to our consolidated financial statements included

at Item 18. of this annual report).

B.4. Global research & development

Redefining immunology as we know it, our immuno-science approach is the bedrock of Sanofi’s research and development

(R&D). Combining our deep heritage and expertise in immunology, we are evaluating pathways of immunity and how they

function independent of specific diseases or pathologies.

Immuno-science is the connector of our R&D strategy, but it does not limit the depth and breadth of our pipeline. We continue to

pursue all areas of urgent unmet need and promising scientific discovery, where we are uniquely positioned to achieve innovation

for patients. This includes seeking out and engaging with external partners, ensuring we have access to the most innovative and

cutting-edge scientific developments in our search of first- or best-in-class medicines.

Our R&D pipeline is detailed in the section “— B.4.1. Biopharma pipeline” below.

Discovering and developing new medicines is a costly, lengthy, and uncertain process and our continuous investments in R&D for

future products and for the launches of newly registered medicines could result in increased costs without a proportionate

increase in revenues. See “Item 3. Key Information — D. Risk Factors” for further information.

(a) Sanofi has an exclusive license to develop and commercialize plozasiran in China, where this medicine was approved in January 2026.

(b) Sanofi has an exclusive license to develop and commercialize aficamten in China, where this medicine was approved in December 2025.

The portfolio of products in clinical development (from Phase 1 to Phase 3) and in registration as of December 31, 2025 is

described in “—E. R&D Appendix.”

Phase 1 studies are the first studies performed in humans, who are mainly healthy volunteers, except for studies in oncology

where Phase 1 studies are performed in patients. Their main objective is to assess the tolerability, the pharmacokinetic profile (the

way the product is distributed and metabolized in the body and how it is eliminated) and where possible the pharmacodynamic

profiles of the new drug (i.e. how the product may react on some receptors).

Phase 2 studies are early controlled studies in patients under closely monitored conditions to show efficacy and short-term

safety, and to determine the dose and regimen for Phase 3 studies.

Phase 3 studies have the primary objective of demonstrating or confirming the therapeutic benefit and safety of the new drug in

the intended indication and population. They are designed to provide an adequate basis for registration.

B.4.1.1. Products in development

Our R&D pipeline consists of innovative projects that are being developed to become first- or best-in-class medicines and

vaccines. These projects are evaluated across four main disease areas (immunology, rare diseases, neurology, and oncology) plus

vaccines, as detailed below.

a) Immunology

Sanofi delivered the first advanced biologic for atopic dermatitis with Regeneron, and this heritage in immunology is the

foundation for our immunoscience approach. Pursuing our ambition to be leader in immunology, we are exploring ways to restore

balance within the immune system, paving the way for treatments that address the root causes of a range of conditions,

including those that may not be commonly associated with an autoimmune or inflammatory response.

B.4.2. R&D Expenditures

Expenditures on research and development amounted to € 7,842 million in 2025 (€ 7,394 million in 2024 ). Research and

development expenditures represented approximately 18.0 % of our net sales in 2025 , compared with 18.0 % in 2024 . R&D spend ,

excluding the 2024 one-off Sobi reimbursement following the registration of ALTUVIIIO in Europe , increased 6.3% y ear over year,

driven by strategic prioritization of key therapeutic growth areas (in particular immunology, rare diseases, neurology and

vaccines) and wind-down costs for the discontinued E. coli sepsis vaccine candidate, as well as new acquisitions and in‑licensing

agreements completed in 2025. Oncology spend was selectively reduced to support portfolio rebalancing to immunology.

B.5. Markets

A breakdown of revenues by segment and by geographical region for 2025 , 2024 , and 2023 can be found at Notes D.34. and

D.35. to our consolidated financial statements, included at Item 18. of this annual report.

The following market shares and ranking information are based on consolidated national pharmaceutical sales data (excluding

vaccines), in constant euros, on a September 2025 Moving Annual Total (MAT) basis. The data are mainly from IQVIA MIDAS local

sales audits supplemented by various other country-specific sources including Knobloch (Mexico), GERS (France) and HMR

(Portugal).

B.5.1. Marketing and distribution

We have business operations in approximately 60 countries and our products are available in more than 160 countries.

A breakdown of our aggregate net sales by geographical region is presented in “Item 5. Operating and Financial Review and

Prospects — Results of Operations — Year Ended December 31, 2025 Compared with Year Ended December 31, 2024 .” Sanofi is

the ninth largest pharmaceutical company globally by sales. Our main markets in terms of net sales are respectively:

• US : we rank twelfth with a market share of 2.2%;

• Europe: we are the sixth largest pharmaceutical company in France where our market share is 4.0%, and we rank sixth in

Germany with a 3.0% market share; and

• other countries: we are ranked twelfth in Japan with a market share of 2.4%, and seventh in China with a market share of 1.6%.

Although specific distribution patterns vary by country, we sell prescription drugs primarily to wholesale drug distributors,

independent and chain retail drug outlets, hospitals, clinics, managed-care organizations and government institutions. Some

products in Rare Diseases and Oncology may also be sold directly to physicians. Our drugs are ordinarily dispensed to patients by

pharmacies upon presentation of a doctor’s prescription. Our vaccines are sold and distributed through multiple channels

including physicians, pharmacies, hospitals, private companies and distributors in the private sector, and governmental entities

and non-governmental organizations in the public and international donor markets.

We use a range of channels from in-person to digital to disseminate information about and promote our products among

healthcare professionals, ensuring that the channels not only cover our latest therapeutic advances but also our established

prescription products, which satisfy patient needs in some therapy areas. In some countries, products are also marketed directly

to patients by way of television, radio, newspapers and magazines, and digital channels (such as the internet), in accordance with

local regulations. National education and prevention campaigns can be used to improve patients’ knowledge of their conditions.

We regularly exhibit at major medical congresses.

Our sales representatives, who work closely with healthcare professionals, use their expertise to promote and provide scientific

information on our drugs, and to inform healthcare professionals when necessary about alternative access to our drugs for their

patients. They represent our values on a day-to-day basis and are required to adhere to a code of conduct and to internal

policies on which they receive training.

Sanofi markets most of its products through its own own sales forces. Nevertheless, Sanofi has entered into and continues to

form alliances to promote/market or co-promote/co-market certain products in specific geographical areas. Our major alliances

are detailed at “Item 5. Operating and Financial Review and Prospects — A.1.7. Financial Presentation of Alliances.” See also

“Item 3. Key Information — D. Risk Factors — We rely on third parties for the discovery, manufacture and marketing of some of

our products.”

B.5.2. Competition

The pharmaceutical industry continues to experience significant changes in its competitive environment.

There are four primary types of competition in the prescription pharmaceutical market:

• competition among pharmaceutical companies to research and develop new patented products or address unmet medical

needs;

• competition among different patented pharmaceutical products for the same therapeutic indication, including competition

for market access, as is currently being observed in particular in the US (but also in other markets around the world). The

number of drugs excluded from leading pharmacy benefit managers’ formularies has increased dramatically over the past

11 years in the US commercial health insurance market, with a total of 1,357 unique medications having faced exclusion for at

least one year from one PBM , mostly in crowded therapeutic areas. For 2025 , the three largest pharmacy benefit managers

(PBMs) – Caremark (CVS Health), Express Scripts (Cigna), and OptumRx (United Health Group) – have again each excluded

600 or more drugs from their standard formularies. Formulary exclusions and utilization management are tools used by payers

to manage prescription drug costs and leverage their negotiating power with manufacturers;

• competition among original and generic products or original biological products and biosimilars, at the end of regulatory

exclusivity or patent protection; and

• competition among generic or biosimilar products.

Generics manufacturers who have received all necessary regulatory approvals for a product may decide to launch a generic

version before the patent expiry date, even in cases where the owner of the original product has already commenced patent

infringement litigation against the generics manufacturer. Such launches are said to be “at risk” for the owner and the promoter

of the generic product because it may be required to pay damages to the owner of the original product in the context of patent

infringement litigation; however, such launches may also significantly impair the profitability of the pharmaceutical company

whose product is challenged.

42 SANOFI FORM 20-F 2025

PART I
ITEM 4. Information on the Company

Drug manufacturers also face intra-product competition through parallel trade, where legally permitted. This refers to the

practice whereby parallel traders or importers purchase drugs in one country and sell them in another country without the

authorization of the original drug manufacturer. This usually occurs in markets where price differences exist due to factors like

varying regulations, taxes or exchange rates. The parallel trader or importer will repackage or resize the original product with

leaflets in the local language and sell it through an alternative channel at a higher price. This situation is of particular relevance in

the EU single market, where such practices have been encouraged by the current regulatory framework. Some of the risks arising

from parallel trade include quality and safety concerns, breach of intellectual property rights and supply chain disruptions (see

“Item 3. Key Information — D. Risk Factors”).

The industry is also facing a proliferation of falsified and substandard medicines, a problem particularly widespread in low- and

middle-income countries. The WHO estimates that 10% of medicines in these regions are falsified, affecting all therapeutic areas

including vaccines. Worldwide, falsified products are an issue, due in part to an exponential rise in internet connectivity of those

engaged in the manufacture, distribution and supply of substandard and falsified medical products.

In Vaccines, there are two primary types of competition:

• competition for innovation in the development of new vaccines, including breakthrough technologies (such as mRNA vaccines

introduced against COVID-19) or address unmet medical needs; and

• competition among different patented (or non-patented) vaccine products marketed for the same therapeutic indication.

In contrast, generics and biosimilars do not directly affect vaccines, which rely on proprietary viral or bacterial strains.

Competition from parallel importers remains limited due to the specific requirements for vaccines, such as the cold chain and the

need for administration by healthcare professionals.

B.5.3. Regulatory framework

The pharmaceutical and health-related biotechnology sectors are highly regulated. Sanofi’s business is subject to varying

degrees of governmental regulation in the countries in which operations are conducted. National and supranational health

authorities, such as the FDA in the US, the EMA and the EC in the EU, and the PMDA and the MHLW in Japan, administer a vast

array of legal and regulatory requirements that dictate pre-approval testing (including testing in human subjects) and quality

standards to maximize the safety and efficacy of a new medical product. These authorities also regulate product labeling,

manufacturing, importation/exportation, safety reporting, marketing and supply chains, as well as mandatory post-approval

requirements and commitments.

Prior to commercializing a pharmaceutical or biological product, approval by relevant regulatory authorities is required, based

upon the authority’s review of submitted pre-approval testing results and pursuant to processes that may vary across

jurisdictions and product type. The submission of an application to a regulatory authority does not guarantee that a license or

approval to market will be granted. Furthermore, each regulatory authority may impose its own requirements during product

development or during the application review. It may refuse to grant approval or require additional data before granting approval,

even in circumstances in which the same product has already been approved in other countries. Regulatory authorities also have

the authority to request product recalls and product withdrawals, to impose penalties for violations of regulations, and ultimately

the ability to revoke product licensure or approval.

Product review and approval can vary from six months or less to several years from the date of application submission, depending

upon the country and regulatory jurisdiction. Factors such as the quality of data and evidence, the review procedures, the nature

of the product, the condition to be treated, and any potential shifts in regulatory priorities, play a major role in the length of time

a product is under review, and whether or not the product is ultimately licensed or approved.

For a description of material risks relating to the regulatory environment in which we operate, refer to “Item 3.D. Risk Factors —

Risks relating to legal and regulatory matters.”

B.5.4. Pricing & reimbursement

We are operating in a new era of drug pricing and market access, driven by sweeping policy changes and shifting market

dynamics in 2026. We are facing heightened uncertainty in a changing world triggered by the US Presidential Administration's

most favored nation (MFN) policy and global price harmonization. See “Item 5. Operating and financial Review and Prospects —

A.1.1 2025 Overview — 2025 Business Developments .”

In this new era, governments and other payers will demand more value for money and superior evidence (e.g. comparative

efficacy studies, real-world patient data, budget modelling), raising the bar for market entry in many countries.

Looking ahead to 2026 and beyond, we anticipate that new policies in the US and EU will have a transformative impact on our

portfolio, on long-term pharma growth and the whole innovation ecosystem.

United States

Overview of the US health insurance system

Commercial insurance is offered widely as part of employee benefit packages and is the main source of employee access to

subsidized healthcare. Some individuals purchase private health plans directly or through marketplaces established under the

SANOFI FORM 20-F 2025 43

PART I
ITEM 4. Information on the Company

Affordable Care Act, while publicly subsidized programs provide coverage for retirees, the indigent, the disabled, uninsured

children, and active or retired military personnel. Double coverage can occur.

Commercial insurance includes:

• Managed Care Organizations (MCOs), which combine the functions of health insurance, delivery of care, and administration.

MCOs use specific provider networks and specific services and products. There are four primary types of managed care plans:

Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), Exclusive Provider Organizations (EPOs),

and Point of Service (POS) plans; and

• PBMs, which serve as intermediaries between insurance companies, pharmacies and manufacturers to negotiate rebates and

discounts on formulary placement for commercial health plans, self-insured employer plans, Medicare Part D plans, and

federal and state government employee plans.

Government insurance includes:

• Medicare , which provides health insurance for retirees and for people with permanent disabilities. The basic Medicare scheme

(Part A) provides hospital insurance only, and the vast majority of retirees purchase additional cover through some or all of

three other plans named Part B, Part C and Part D. Part D enables Medicare beneficiaries to obtain outpatient drug coverage.

Almost two-thirds of all Medicare beneficiaries have enrolled in Part D plans;

• Medicaid , which provides health insurance for low-income families, certain qualified pregnant women and children, individuals

receiving supplemental security income, and other eligible persons determined on a state-by-state basis; and

• TRICARE , which provides health insurance for uniformed service members, retirees, and their families including

comprehensive healthcare, prescription and dental coverage.

The US remains the world’s largest pharmaceutical market, projected to reach $1.2 trillion by 2029. It continues to serve as the

primary innovation hub with strong access to new therapies.

However, 2026 marks a pivotal shift with two major federal policies reshaping the drug pricing landscape. The Inflation

Reduction Act (IRA) introduces negotiated prices for high-cost Medicare drugs, while the MFN voluntary agreements, signed with

the US Administration , provide tariff exemptions in return for substantial discounts on select medicines, including those for

Medicaid, Medicare, the direct-to-consumer market and future launches.

In May 2025, the US administration issued the MFN pricing executive order , which aims to align US drug prices with the lowest

prices paid in a basket of comparable OECD nations. On December 19, 2025, we signed a voluntary MFN agreement with the US

government. Under this agreement, we committed to align Medicaid prices on certain wholly owned medicines with other high

income countries; cut prices by 61% for select diabetes, cardiovascular, neurological, and cancer drugs; offer around 70%

discounts via the TrumpRx DTC platform (e.g. Plavix from $756 to $16); and expand the $35 monthly insulin cap to all US patients

effective January 1, 2026. The new pricing agreement is expected to accelerate the commoditization of our insulins and mature

US portfolio. The Centers for Medicare & Medicaid Services (CMS) have also introduced two new mandatory five-year drug

pricing models: the Global Benchmark for Efficient Drug Pricing (GLOBE) Model for Medicare Part B launching on October 1,

2026, and the Guarding US Medicare Against Rising Drug Costs (GUARD) Model for Medicare Part D launching on January 1,

1. Both models will apply an MFN international reference pricing approach to selected Medicare covered medicines, aiming to

align US prices more closely with international benchmarks. If implemented, these mandatory drug pricing models could have a

material adverse effect on our business.

The IRA, signed into law in August 2022, will continue to exert unprecedented price pressure that will compress margins and

shorten product lifecycles (eight years for small molecules and 12 years for biologics). Some of the key provisions of the law relate

to Medicare price negotiations, inflation penalties on price increases, and Medicare Part D redesign, all phased in between 2022

and 2026. The most impactful change relates to Medicare drug price negotiations, starting with ten Part D drugs in 2026,

expanding to 15 drugs in 2027–2028, and 20 drugs annually from 2029 onward, including Part B. Negotiated rebates average

approximatively 62%, creating significant revenue pressure. The first negotiated prices took effect on January 1, 2026, with the

negotiated prices of the next 15 drugs expected to be announced by February 2026 . The IRA is projected to cut federal drug

spending by $290 billion over the next decade, according to estimates from the Congressional Budget Office (CBO), signaling

significant headwinds for industry revenue growth and innovation.

In addition, in commercial channels, we continue to face intensifying pricing pressure and gross-to-net (GTN) erosion from

payers and pharmacy benefit manager s (PBMs), resulting in tighter utilization management and a dramatic increase of formulary

exclusions, tighter utilization management, higher rebate demands, and accumulator/maximizer programs.

Moreover, rapidly shifting federal vaccine policies drive uncertainty, primarily triggered by recent changes to the Advisory on

Immunization Practices ( ACIP) membership and scepticism toward existing immunization frameworks. These policy changes may

have long-term market implications and affect future pandemic preparedness.

ITEM 4. Information on the Company

Europe

In Europe, the pharmaceutical environment remains highly fragmented and challenging, shifting from traditional national

budget constraints to a complex framework shaped by the US MFN policy and sweeping EU‑level legislative reforms. The

combined impact of MFN pricing pressure and a potential new debt crisis in key European economies has shifted political

attention back to the pharmaceutical sector, renewing recognition of its role as a strategic engine of economic growth at both

national and European levels.

The US MFN policy is creating significant upward pricing pressures across Europe. Driven by efforts to rebalance global drug

prices, MFN pressures are pushing major EU countries to maintain higher prices for innovative medicines in order to avoid price

spillovers in the US and other markets. As a result, companies are exercising tighter control over EU launches and volumes,

prioritizing price integrity over speed of access.

At the same time, many European health systems that rely on clawbacks, paybacks, and mandatory rebates to contain

pharmaceutical spending are now revising their national policies to adapt to the evolving pricing landscape. These

mechanisms create high barriers to market entry for new products, with nearly half of innovative medicines remaining unavailable

to patients in 2024, according to the EFPIA's Patients W.A.I.T Indicator Survey. Recent reforms signal attempts to balance fiscal

cost-containment with competitiveness and innovation incentives, as exemplified by the UK-US landmark deal signed on

December 1, 2025, capping future UK clawback at around 15%, raising NICE's cost-effectiveness threshold to £25k-£35k per

QALY, and committing a budget increase for innovative drugs of 0.6% of GDP by 2035. However, significant delays persist across

Europe. France, for example, often requires 12 to 24 months for reimbursement decisions, while other markets experience similar

lengthy timelines. Germany stands out as the only major EU market providing immediate access.

Moreover, new EU-level regulations are reshaping the European pharmaceutical landscape. The EU Pharma Package, aimed

at modernizing the regulatory framework, preserves the eight-year baseline data protection, while introducing a more flexible,

conditional exclusivity model, including extensions for products that address unmet medical needs or meet certain innovation

criteria. Despite improvements to the initial Commission proposal, concerns remain about the expanding Bolar exemption

enabling earlier generic entry, and new access and supply obligations for manufacturers expected to apply from January 2027,

increasing regulatory and compliance burdens. The new legislation is anticipated to be adopted in the first quarter of 2026, with

implementation foreseen by mid-2028.

In parallel, the EU Health Technology Assessment (HTA) Regulation, in force since January 2025, mandates Joint Clinical

Assessments (JCAs) for oncology and advanced therapy medicinal products ( ATMPs), with orphan drugs following in 2028

and all products, including vaccines, by 2030. The new mandatory JCAs tighten evidence requirements and significantly increase

the workload for industry. In 2025, 13 initial JCAs were completed, comprising 10 oncology therapies and 3 ATMPs. The first wave

of JCA reports, expected in 2026, will bring clarity on how the new process operates in practice and how joint assessments will be

used by national HTA bodies across Member States.

China

China is accelerating healthcare reforms under Healthy China 2030, focusing on managing the growing burden of chronic

diseases such as cancer, diabetes, and cardiovascular conditions while balancing access to innovation with cost containment.

Regulatory timelines have improved significantly, as illustrated by Dupixent gaining approval within six months through an

accelerated review process.

China is emerging as a global biopharma innovation hub, accounting for 30% of global clinical trial starts in 2024 according to

IQVA's Global Trends in R&D 2025 report. In 2023, 30 medicines discovered in China were approved, representing 37% of all new

drugs. The biotech sector is growing at a rate of 70% annually, and one in four innovative drug discoveries now originates in

China. Western pharmaceutical companies increasingly license early-stage assets from Chinese innovators, signaling a shift in

global innovation geography.

Overall, the landscape is becoming more predictable with rapid innovation and evolving funding models, albeit with steep price

cuts and intensifying local competition.

Pricing pressure remains intense, driven by NRDL negotiations and Volume-Based Procurement (VBP) tenders, where the

lowest price prevails. Access to innovative therapies has expanded rapidly, supported by annual NRDL updates. Effective January

1, 2026, the new NRDL list added 114 new drugs, of which 50 are Class I innovative drugs (i.e. China as the first global launch

country), and removed 29 drugs, signaling stricter evidence standards. VBP is expected to expand to multi-source biologics in

2026, building on VBP insulin pilots. Since its launch in 2018, VBP has become a key policy tool to control drug costs, with a

cumulative 490 drugs included through 11 rounds, and average price cuts ranging from 48% to 70%.

At the same time, funding models are evolving through a dual-track system that separates basic coverage under NRDL from

premium-priced therapies supported by commercial health insurance (CHI). The new Commercial Health Insurance Innovative

Drug List (CHIIDL), also effective January 2026, enables access to 19 high-cost, innovative drugs that address rare and unmet

needs, with lower price cuts (15%–50%) compared to NRDL’s average 60%. The new commercial list is expected to grow the role

of CHI in China, projected to increase from less than 8% today to nearly 30% coverage by 2035, creating substantial

opportunities for innovative medicines.

Pricing and reimbursement pressures are being felt in other regions and countries around the globe.

To overcome these challenges, we are developing tailored market access strategies early in the drug development process,

engaging in dialogue with payers and multiple stakeholders throughout the lifecycle, based on a thorough understanding of

evolving market dynamics.

ITEM 4. Information on the Company

B.6. Patents, intellectual property and other rights

Intellectual property rights are essential to our business because they protect our innovations and investments in research and

development, manufacturing and marketing of our products. Intellectual property rights include patents, trademarks, copyrights,

know‑how, trade secrets and regulatory-based protection.

Patent protection

We own a broad portfolio of patents, patent applications and patent licenses worldwide. These patents are of various types and

may cover: active ingredients; pharmaceutical formulations; product manufacturing processes; intermediate chemical

compounds; therapeutic indications/methods of use; technology platforms; delivery systems; digital applications; and enabling

technologies, such as assays. Patent protection is considered, in the aggregate, to be of material importance to the marketing

and sales of our products.

Patent protection for individual products typically extends for 20 years from the patent filing date in countries where we seek

patent protection. A substantial part of the 20-year life span of a patent on a new molecule (small molecule or biologic) has

generally already passed by the time the related product obtains marketing authorization. As a result, the effective period of

patent protection for an approved product’s active ingredient is significantly shorter than 20 years. In some cases, the period of

effective protection may be extended by procedures established to compensate regulatory delay in Europe (via Supplementary

Protection Certificate or SPC), in the US (via Patent Term Extension or PTE), in Japan (PTE), and in China (PTE).

The protection a patent provides to the related product depends upon the type of patent and its scope of coverage, and may

also vary from country to country.

We monitor our competitors and vigorously seek to challenge patent infringers when such infringement would negatively impact

our business objectives. See note D.22.b. to the consolidated financial statements included at Item 18. of this annual report.

The expiration or loss of a patent covering a new molecule, typically referred to as a compound patent, may result in significant

competition from generic or biosimilar products and can result in a dramatic reduction in sales of the original branded product

(see “Item 3. Key Information — D. Risk Factors”). In some cases, it is possible to continue to benefit from a commercial

advantage through product manufacturing trade secrets or other types of patents. Certain categories of products, such as

traditional vaccines and insulin, were historically relatively less reliant on patent protection and may in many cases have no patent

coverage. It is increasingly frequent for novel vaccines also to be patent protected.

Regulatory exclusivity

In some markets, including the EU and the US, many of our pharmaceutical products may also benefit from multi-year regulatory

exclusivity periods, during which a generic or biosimilar competitor may not rely on our clinical study and safety data in its drug

application. This exclusivity operates independently of patent protection and may protect the product from generic or biosimilar

competition even if there is no patent covering the product.

United States

• The FDA may not grant final marketing authorization to a generic competitor for a New Chemical Entity (NCE) until the

expiration of the regulatory exclusivity period (five years) that commences upon the first marketing authorization of the

reference listed drug.

• Significant new uses of existing NCEs, including new indications, may qualify for an additional three years of regulatory

exclusivity if certain conditions are met.

• For biological drugs, the FDA may not approve a biosimilar application until 12 years after the date on which the reference

product was first licensed.

• Pediatric extensions are available under certain conditions of the Hatch-Waxman Act by providing data on pediatric studies.

Under such cases the FDA allows for an extension of regulatory exclusivity and patent life by six months, to the extent these

protections have not already expired (the so-called “pediatric exclusivity”).

• Orphan drug exclusivity may be under certain circumstances to drugs intended to treat rare diseases or conditions.

European Union

• Regulatory exclusivity is available in two forms: data exclusivity and marketing exclusivity.

• Generic or biosimilar drug applications will not be accepted for review until eight years after the first marketing authorization

(data exclusivity). This eight-year period is followed by a two-year period during which generics or biosimilars cannot be

marketed (marketing exclusivity).

• The marketing exclusivity period can be extended to three years if, during the first eight-year period, the marketing

authorization holder obtains an authorization for one or more new therapeutic indications which are deemed to provide a

significant clinical benefit over existing therapies. This is known as the “8+2+1” rule.

• Pediatric extensions - A regulation on pediatric medicines provides for pediatric research obligations with potential associated

rewards including extension of supplementary patent protection and six-month regulatory exclusivity for pediatric marketing

authorization (for off-patent medicinal products).

• Orphan drug exclusivities also exist in the EU.

46 SANOFI FORM 20-F 2025

PART I
ITEM 4. Information on the Company

Japan

• The regulatory exclusivity period varies, but is generally four to six years for drugs for a specific use, and for medicinal products

with new indications or with new dosages; eight years for drugs containing a new chemical entity; ten years for orphan drugs,

and for new drugs requiring pharmaco-epidemiological study; six to eight years for innovative drugs (“SAKIGAKE” products),

and for orphan drugs with a new ethical combination or new mode of administration; and six years for other medicinal

products, such as new prescription combination drugs or drugs requiring a new mode of administration.

• There is no pediatric research extension of patent protection for patented medicinal products. However, regulatory exclusivity

may be extended from eight to ten years.

Emerging markets

One of the main limitations on our operations in emerging market countries is the lack of effective intellectual property protection

or enforcement for our products, which frequently do not provide non-patent exclusivity for innovative products. While the

situation has gradually improved, the lack of protection for intellectual property rights or the lack of robust enforcement poses

difficulties in certain countries. Additionally, in recent years a number of countries have waived or threatened to waive intellectual

property protection for specific products, for example through compulsory licensing of generics. See “Item 3. Key Information —

D. Risk Factors — Risks Relating to Sanofi’s Structure and Strategy — The globalization of our business exposes us to increased

risks in specific areas.”

Product and patent overview

We summarize in the table below the intellectual property coverage (in some cases through licenses) of our most significant

marketed products in terms of sales, in our major markets. In the discussion of patents below, we focus on active ingredient

patents (compound patents) and, in the case of NCEs, on any later filed patents listed as applicable in the FDA’s list of Approved

Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”) or in its foreign equivalents. For biologics, the

Orange Book listing does not apply.

The table provides a list of expiration dates, which include six-month pediatric extensions when applicable, and when indicated,

extensions due to Patent Term Adjustment (PTA) or other regulatory delays. Where patent terms have expired we indicate such

information and mention whether generics or biosimilars are on the market.

References below to patent protection in Europe indicate the existence of relevant patents in most major markets in the EU.

Specific situations may vary by country.

We additionally set out any regulatory exclusivity from which these products continue to benefit in the EU, US or Japan.

Regulatory exclusivities presented below incorporate any pediatric extensions obtained. While EU regulatory exclusivity is

intended to be applied throughout the EU, in some cases Member States have taken positions prejudicial to our exclusivity rights.

For regulatory exclusivity in the US, only NCE or BLA are provided. In the EU, the regulatory exclusivity based on the first MA is

given.

PART I
ITEM 4. Information on the Company

Third-party patents and challenges to intellectual property

Patents held or licensed by Sanofi do not in all cases provide effective protection against a competitor’s generic or biosimilar

version of our products. For example, notwithstanding the presence of unexpired patents, competitors launched generic versions

of Allegra in the US (prior to the product being switched to over-the-counter status) and Multaq in the EU.

We caution the reader that there can be no assurance that we will prevail when we assert a patent in litigation and that there may be

instances in which Sanofi determines that it does not have a sufficient basis to assert one or more of the patents mentioned in this

report, for example in cases where a competitor proposes a formulation not appearing to fall within the claims of our formulation

patent; a salt or crystalline form not claimed by our composition of matter patent; or an indication not covered by our method of use

patent. See “Item 3. Key Information — D. Risk Factors — Risks Relating to Legal and Regulatory Matters — We rely on our patents

and other proprietary rights to provide exclusive rights to market certain of our medicines and vaccines. If such patents and other

rights were limited, invalidated, or circumvented, our financial results could be adversely affected ” As disclosed in Item 8. of this

annual report, we are involved in significant litigation concerning the patent protection of a number of our products.

In addition to directly challenging our intellectual property rights, in some circumstances a competitor may be able to market a

generic version of one of our products.

In the US, competitor generic companies can challenge patents by filing Abbreviated New Drug Applications (ANDAs) to receive

authority to market a generic version of our approved products, by demonstrating that the purportedly generic version has the

same properties (safety and other technical data) as the original approved product. Our products and patents are also subject to

challenge by under section 505(b)(2) of the US Federal Food, Drug, and Cosmetic Act, which allows for approval for a wide range

of products, especially for those products that represent only a limited change from an existing approved drug.

Similarly, entities wishing to market a generic biologic can utilize an abbreviated approval pathway established in the PHS Act.

This §351(k) pathway enables an applicant to rely on a reference product sponsor’s data when seeking approval of a biological

product shown to be biosimilar (highly similar with no clinically meaningful differences) or interchangeable with an FDA-licensed

reference BLA product. See also “— B.5.3. Regulatory Framework” above.

In the EU, a generic drug manufacturer may only reference the data of the regulatory file for the original approved product after

data exclusivity has expired. Generic products may be approved for marketing following the expiration of marketing exclusivity

without regard to the patent holder’s rights. Nevertheless, in most of these jurisdictions once the competing product is launched,

and in some jurisdictions even prior to launch (once launch is imminent), the patent holder may seek an injunction against such

marketing if it believes its patents are infringed. See Item 8. of this annual report.

We seek to defend our patent rights vigorously in these cases. Success or failure in the assertion of a given patent against a

competing product is not necessarily predictive of the future success or failure in the assertion of the same patent. See “Item 3.

Key Information — D. Risk Factors — Risks Relating to Legal and Regulatory Matters — We rely on our patents and other

proprietary rights to provide exclusive rights to market certain of our medicines and vaccines. If such patents and other rights

were limited, invalidated, or circumvented, our financial results could be adversely affected .”

B.7. Production and raw materials

We have opted to manufacture the majority of our products in-house. There are three principal stages in our production process:

the manufacture of active ingredients, the transformation of those ingredients into drug products or vaccines, and the final

packaging.

Our general policy is to produce our key active ingredients and main drug products at our own plants in order to reduce our

dependence on external suppliers. We also rely on third parties for the manufacture and supply of specific active ingredients,

drug products and medical devices. Active ingredients are manufactured using raw materials sourced from suppliers who have

been subject to rigorous selection and approval procedures, in accordance with international standards and our own internal

directives. We have outsourced some of our production under supply contracts associated with acquisitions of products or

businesses or with Sanofi plant divestitures, or to establish a local presence to capitalize on growth in emerging markets. Our

pharmaceutical subcontractors follow our general quality and logistics policies, as well as meeting other criteria.

We also obtain active ingredients from third parties under collaboration agreements. This applies in particular to the monoclonal

antibodies developed with Regeneron.

Our production sites are divided into three categories:

• global sites, which serve all markets: located mainly in Europe, these facilities are dedicated to the manufacture of our active

ingredients, injectable products, and a number of our main solid-form products;

• regional sites, which serve markets at regional level, giving us a strong industrial presence in emerging markets; and

• local sites, which serve their domestic market only.

Vaccines produces vaccines at various sites, with the main locations situated in France, the US, Canada, India, Mexico and China.

The pharmaceutical site at Le Trait (France) also contributes to Vaccines’ industrial operations by making its sterile filling facilities

available for vaccine manufacturing.

All of our production facilities are good manufacturing practice (GMP) compliant, in line with international regulations.

SANOFI FORM 20-F 2025 49

PART I
ITEM 4. Information on the Company

Our main sites are approved by the FDA :

• the Specialty Care facilities in the US (Framingham MA and Northborough MA), France (Lyon Gerland, Vitry-sur-Seine,

Le Trait), Germany (Frankfurt), Ireland (Waterford) and Belgium (Geel);

• the General Medicines facilities in Germany (Frankfurt), France (Aramon, Sisteron, Ploermel, Ambarès and Tours), Italy (Anagni

and Scoppito), Singapore (Jurong) and the US (Ridgefield NJ);

• the Vaccines facilities in France (Marcy l’Étoile, Le Trait, Val-de-Reuil and Neuville-sur-Saône), the US (Swiftwater PA) and

Canada (Toronto); and

• during 2025, the Opella facilities approved by FDA in France (Compiègne) and the US (Chattanooga TN) were divested as part

of the Opella divestment. More details are given above at section "— B.3. Opella.”

Wherever possible, we seek to have multiple plants approved for the production of key active ingredients and our strategic

finished products (this is the case with Lovenox and Dupixent, for example).

More details about our manufacturing sites are given below at section “— D. Property, Plant and Equipment.”

B.8. Insurance and risk coverage

We are protected by five main insurance programs, relying not only on the traditional corporate insurance and reinsurance

market but also on our direct insurance company, Carraig Insurance DAC (Carraig).

These five key programs cover Property & Business Interruption; General & Product Liability; Stock & Transit; loss and liability

arising from cyber and digital risks; and Directors & Officers Liability.

Carraig participates in our coverage for various lines of insurance including Property, Stock & Transit, Cyber/Digital, and General

& Product Liability. Carraig is run under the supervision of the Irish and European regulatory authorities, is wholly owned by

Sanofi, and has sufficient resources to meet those portions of our risks that it has agreed to cover.

Carraig sets premiums for our entities at market rates. Claims are assessed using the traditional models applied by insurance and

reinsurance companies, and Sanofi's reserves are regularly verified and confirmed by independent actuaries.

Our Property & Business Interruption program covers all our entities worldwide, in all territories where it is possible to use a

centralized program operated by Carraig. By sharing risk between our entities, this approach enables us to set deductibles and

cover appropriate to the needs of local entities before the market attachment point. It also incorporates a prevention program,

including a comprehensive site visit schedule covering our production, storage, research and distribution facilities and

standardized repair and maintenance procedures across all sites.

The Stock & Transit program protects all goods owned by Sanofi while they are in transit nationally or internationally, whatever

the means of transport, and all our inventories wherever they are located. Sharing risk between our entities through Carraig

means that we can set deductibles at appropriate levels, for instance differentiating between goods that require temperature

controlled distribution and those that do not. We have developed a prevention program with assistance from experts,

implementing best practices in this area at our distribution sites.

Our Cyber/Digital insurance program protects our operations against loss originating from various sources, and against liability in

respect of data security. Centralized through Carraig, the program enables us to set deductibles and cover appropriate to the

needs of local entities before the market attachment point.

Our General & Product Liability program was renewed in 2025 for all our subsidiaries worldwide in all territories where it was

possible to do so. For several years, insurers have been reducing product liability coverage because of the difficulty of

transferring risk for some products that have been subject to numerous claims.

The principal risk exposure for our pharmaceutical products is covered with low deductibles at country level, with a greater

proportion of risk being retained. The level of risk self-insured by Sanofi (including via Carraig) before the market attachment

point enables us to retain control over the management and prevention of risk. Our negotiations with third-party insurers and

reinsurers are tailored to our specific risks. In particular, they allow for differential treatment of products in the development

phase, for discrepancies in risk exposure between European countries and the US and for specific issues arising in certain

jurisdictions. Coverage is adjusted every year to take account of the relative weight of new product liability risks such as those

arising out of biotechnologies and new technology platforms.

Our coverage for risks that are not specific to the pharma-biotech industry (general liability) is designed to address the potential

impacts of our operations.

For all the insurance programs handled by Carraig, outstanding claims are covered by provisions for the estimated cost of settling

all claims incurred but not paid at the balance sheet date, whether reported or not, together with all related claims handling

expenses. Where there is sufficient data history from Sanofi or from the market for claims made and settled, management – with

assistance from independent actuaries – prepares an actuarial estimate of our exposure to unreported claims for the risks

covered. The actuaries perform an actuarial valuation of the company’s Incurred But Not Reported (IBNR) and Allocated Loss

Adjustment Expense (ALAE) liabilities at year end. Two ultimate loss projections (based upon reported losses and paid losses,

respectively) are computed each year using various actuarial methods including the Bornhuetter-Ferguson method; those

projections form the basis for the provisions set.

The Directors & Officers Liability program protects all legal entities under our control, and their directors and officers. Carraig is

not involved in this program.

50 SANOFI FORM 20-F 2025

PART I
ITEM 4. Information on the Company

We also operate other insurance programs, but these are of much lesser importance than those described above.

All our insurance programs are backed by highly-rated insurers and reinsurers and are intended to be designed in such a way that

we can integrate most newly acquired businesses without interruption of cover. Our insurance coverage has been designed to

reflect our risk profile and the capacity available in the insurance market. By centralizing our major programs, we are able to

provide what we believe to be excellent, cost effective protection .

B.9. Health, Safety, and Environment

Our manufacturing and research operations are subject to increasingly stringent health, safety and environmental (HSE) laws and

regulations. These laws and regulations are complex and rapidly changing, and Sanofi invests the necessary sums in order to

comply with them. This investment, which aims to respect HSE matters, varies from year to year.

Applicable environmental laws and regulations may require us to reduce the effects of chemical substance discharge at our

various sites. The sites in question may belong to Sanofi, and may be currently operational, or may have been owned or

operational in the past. In this regard, Sanofi may be held liable for the costs of removal or remediation of hazardous substances

on, under or in the sites concerned, or on sites where waste from activities has been stored, without regard to whether the owner

or operator knew of or under certain circumstances caused the presence of the contaminants, or at the time site operations

occurred the discharge of those substances was authorized.

As is the case for a number of companies in the pharmaceutical, chemical and intense agrochemical industries, soil and

groundwater contamination has occurred at some of our sites in the past, and may still occur or be discovered at others. In

Sanofi’s case, such sites are mainly located in the US, Germany and France. As part of a program of environmental surveys

conducted over the last few years, detailed assessments of the risk of soil and groundwater contamination have been carried out

at current and former Sanofi sites. In cooperation with national and local authorities, Sanofi regularly assesses the rehabilitation

work required and carries out such work when appropriate. Remediation works have just been completed at Beaucaire in France.

Long-term rehabilitation work is in progress or planned in Mount Pleasant, Portland in the US; Frankfurt in Germany; Valernes,

Septèmes and Limay in France; and on a number of sites divested to third parties and covered by contractual environmental

guarantees granted by Sanofi.

We may also have potential liability for investigation and clean-up at several other sites. We have established provisions for the

sites already identified and to cover contractual guarantees for environmental liabilities for sites that have been divested. In

France specifically, we have provided the financial guarantees to the authorities as required under French regulations for

environmental protection in connection with the operation of activities on French sites.

Potential environmental contingencies arising from certain business divestitures are described in Note D.22.d. to the consolidated

financial statements. In 2025 , Sanofi spent €31 million on rehabilitating sites previously contaminated by soil or groundwater

pollution.

Due to changes in environmental regulations governing site remediation, our provisions for remediation obligations may not be

adequate due to the multiple factors involved, such as the complexity of operational or previously operational sites, the nature of

claims received, the remediation techniques involved, the planned timetable for rehabilitation, and the outcome of discussions

with national regulatory authorities or other potentially responsible parties, as in the case of multiparty sites. Given the long

industrial history of some of our sites and the legacy obligations arising from the past involvement of Aventis in the chemical and

agrochemical industries, it is impossible to quantify the future impact of these laws and regulations with precision.

See “Item 3.D. Risk Factors — Environmental and safety risks of our industrial activities .”

We have established, in accordance with our current knowledge and projections, provisions for cases already identified and to

cover contractual guarantees for environmental liabilities relating to sites that have been divested. In accordance with

Sanofi standards, a comprehensive review is carried out once a year on the legacy of environmental pollution. In light of

data collected during this review, we adjusted our provisions to € 493 million as of December 31, 2025 versus € 474 million as

of December 31, 2024 . The terms of certain business divestitures, and the environmental obligations and retained environmental

liabilities relating thereto, are described in Note D.22. to our consolidated financial statements.

To our knowledge, Sanofi did not incur any liability in 2025 for non-compliance with current HSE laws and regulations that could

be expected to significantly jeopardize its activities, financial situation or operating income. We also believe that we are in

substantial compliance with current HSE laws and regulations and that all the environmental permits required to operate our

facilities have been obtained.

Regular HSE audits are carried out by Sanofi in order to assess compliance with standards (which implies compliance with

regulations) and to initiate corrective measures (26 entities audited, grouped into 21 internal audits performed in 2025 ). Moreover,

in 2025, 180 specific visits were performed jointly with experts representing our insurers.

Sanofi has implemented a worldwide master policy on HSE to promote the health and well-being of the employees and

contractors working on its sites and respect for the environment. We consider this master policy to be an integral part of our

commitment to social responsibility. In order to implement this master policy, Sanofi key requirements have been drawn up in the

key fields of HSE management, HSE leadership, safety in the workplace, process safety, occupational hygiene, health in the

workplace and protection of the environment. However, despite these efforts, Sanofi may be unsuccessful in the implementation

of its policy to reduce and mitigate the harmful effects of its activities on the health and safety of its employees, customers or the

general public and on the environment more generally. See “Item 3. Key information — D. Risk Factors” for further information.

SANOFI FORM 20-F 2025 51

PART I
ITEM 4. Information on the Company

Health

From the development of compounds to the commercial launch of new drugs, Sanofi research scientists continuously assess the

effect of products on human health. This expertise is made available to employees through two committees responsible for

chemical and biological risk assessment. Sanofi’s COVALIS (Comité des Valeurs Limites Internes Sanofi) Committee is responsible

for the hazard determination and classification of all API and synthesis intermediates handled at Sanofi facilities. This covers all

active ingredients handled in production at company sites or in processes sub-contracted for manufacture. Any important issues

involving raw materials or other substances that lack established occupational exposure limits may also be reviewed. The

COVALIS Committee determines the occupational exposure limits required within Sanofi. Our TRIBIO Committee is responsible

for classifying all biological agents according to their degree of pathogenicity and virulence, and applies rules for their

containment and the preventive measures to be respected throughout Sanofi. See “Item 3. Key Information — D. Risk Factors

— Environmental and safety risks of our industrial activities — Risks from manufacturing activities and the handling of hazardous

materials could adversely affect our results of operations and reputation .”

Appropriate occupational hygiene practices and programs are defined and implemented in each site. These practices consist

essentially of containment measures for collective and individual protection against chemical and biological exposure in all

workplaces where chemical substances or biological agents are handled. All personnel are monitored with an appropriate medical

surveillance program, based on the results of professional risk evaluations linked to their duties.

In addition, dedicated resources have been created to implement the European Regulation on Registration, Evaluation,

Authorization and Restriction of Chemicals (REACH) and the European Regulation on Classification, Labeling and Packaging of

chemicals (CLP). To fully comply with REACH, Sanofi has registered the relevant hazardous chemical substances with the

European Chemicals Agency (ECHA).

While these measures focus on managing chemical and biological risks, Sanofi's commitment to employee well-being extends

beyond safety protocols. Through the All Well program, Sanofi offers comprehensive health and wellbeing support to all its

employees. This program supports mental and physical health, providing various global and local resources to promote healthy

nutrition, physical activity, vaccination, and health checkups, as well as a Global Employee Assistance Program, ensuring a holistic

approach to employee health and safety.

Safety

Sanofi has rigorous policies to identify and evaluate safety risks and to develop preventive safety measures, and methods for

checking their efficacy. Additionally, Sanofi invests in training that is designed to instill in all employees a sense of concern for

safety, regardless of their duties. These policies are implemented on a worldwide scale to ensure the safety of all employees and

to protect their health. Each project, whether in research, development or manufacturing, is subject to evaluation procedures,

incorporating the chemical substance and process data communicated by the COVALIS and TRIBIO Committees described

above. The preventive measures are designed primarily to reduce the number and seriousness of work accidents and to minimize

exposures involving permanent and temporary Sanofi employees as well as our sub-contractors.

The French chemical manufacturing sites in Aramon and Sisteron are upper-tier Seveso sites according to the Seveso III

regulations (from the name of the European directive that deals with potentially dangerous establishments where dangerous

substances may be present in quantities exceeding certain thresholds to prevent major accidents and limit their consequences).

In accordance with French law on technological risk prevention, the French sites are also subject to heightened security

inspections due to the toxic or flammable materials stored on the sites and used in the operating processes. In Europe, our

Frankfurt site is listed as a lower-tier Seveso site.

Risk assessments of processes and installations are drawn up according to standards and internal guidelines incorporating the

best state of the art benchmarks for the industry. These assessments are used to fulfill regulatory requirements and are regularly

updated. Particular attention is paid to any risk-generating changes such as process or installation changes, as well as changes in

production scale and transfers between industrial or research units.

We are using specialized process safety-testing laboratories that are fully integrated into our chemical development activities,

apply methods to obtain the physico-chemical parameters of manufactured chemical substances (intermediate chemical

compounds) and apply models to measure the effect of potentially leachable substances in the event of a major accident. In

these laboratories the parameters for qualifying hazardous reactions are also determined, in order to define scale-up process

conditions while transferring from development stage to industrial scale. We use these data to enhance the relevance of our risk

assessments.

We believe that the safety management systems implemented at each site, the hazard studies carried out and the risk

management methods implemented, as well as our third-party property insurance policies covering any third-party physical

damage, are consistent with legal requirements and the best practices in the industry, although no guarantee can be given that

they will prevent accidents of various kinds.

We have also designed a new Global Safety Culture program – “Leading Safety” – to help protect the health and safety of our

employees, contractors and communities. It is based on five positive performance drivers: strengthen safety leadership; focus on

key risks; increase managerial skills; improve safety barriers and the effectiveness of controls; and increase reports of unsafe acts

& hazardous conditions.

Environment

Beyond healthcare, we have taken steps to address the environmental impacts of our products and activities and to help

strengthen our resilience in the face of environmental changes. We have identified a number of environmental challenges

relevant to our businesses: greenhouse gas emissions and climate disruption; eco-design; water; pharmaceuticals in the

environment; waste; and biodiversity.

We have been implementing environmental initiatives since 2010. More recently, we established the Planet Care program, which

seeks to address environmental impacts across the value chain.

We have also taken measures to seek to reduce our greenhouse gas emissions and to promote circularity and the use of

sustainable resources . We have set both medium-term and long-term targets. See “Cautionary statement regarding

forward-looking statements” and “Item 3.D. Risk Factors.”

May 2022 and the divestment of Opella in April 2025 (for a description of the main such events over the past three years, refer to

“A. History and Development of the Company” above).

In certain countries, we carry on some of our business operations through joint ventures with local partners. In addition, we have

entered into worldwide collaboration agreements, in particular with Regeneron on Dupixent and Kevzara and with AztraZeneca

on Beyfortus. For further information, refer to Note C. “Principal Alliances” to our consolidated financial statements, included at

Item 18. of this annual report.

C.2. Internal organization of activities

Sanofi and its subsidiaries collectively form a group organized around a Biopharma operating segment (Immunology, Rare

diseases, Neurology, Oncology, Other Medicines, and Vaccines). See “Item 5. Operating and Financial Review and Prospects —

A.1.1. 2025 Overview .”

Sanofi's R&D function is structured around two main areas:

• Medicines: under the responsibility of Sanofi and Genzyme Corporation; and

• Vaccines: under the responsibility of Sanofi Pasteur and Sanofi Pasteur, Inc.

The R&D organization operates in an integrated manner on a global scale, with centralized definition of strategic priorities and

global coordination of research programs. These main entities subcontract research and development activities to subsidiaries

with the appropriate technical and scientific capabilities.

Sanofi and its main subsidiaries grant licenses for patents, manufacturing know-how, and trademarks to their French and

international subsidiaries. These licensed subsidiaries handle the manufacturing, marketing, and distribution of Sanofi medicines

and vaccines, either directly to end customers or through local distribution subsidiaries.

Our industrial property rights, patents and trademarks are mainly held by the following legal owner: Sanofi, Sanofi Biotechnology,

and Sanofi R&D Vaccins (formerly Sanofi Pasteur) (France); Sanofi-Aventis Deutschland GmbH (Germany); Ablynx (Belgium);

Kymab Ltd (UK;, Genzyme Corporation, Bioverativ, Inc., Kadmon Corporation LLC, Amunix Pharmaceuticals, Inc., Principia

Biopharma, Inc., Sanofi Vaccines US Inc (formerly Sanofi Pasteur, Inc.), sanofi-aventis US LLC, Translate Bio , Synthorx, Inc., and

Provention Bio, Inc. (US); and Sanofi Vaccines Canada Ltd (formerly Sanofi Pasteur Limited) (Canada).

In Pharmaceuticals, research and development activities are conducted at the following sites:

• two operational sites in France: Montpellier and Vitry-sur-Seine/Alfortville;

• two sites in the rest of Europe (Germany and Belgium), the larger of which is in Frankfurt (Germany);

• three sites in the US: Bridgewater, Cambridge and Framingham/Waltham ; and

• three sites in China (Beijing, Shanghai and Chengdu).

In Vaccines, research and development activities are conducted at the following sites:

• Swiftwater, Cambridge and Orlando (US);

• Marcy-l’Étoile/Lyon (France); and

• Toronto (Canada).

D.3. Acquisitions, capital expenditures and divestitures

The carrying amount of our property, plant and equipment at December 31, 2025 was € 10,052 million. During 2025 , we

invested € 1,822 million (see Note D.3. to our consolidated financial statements, included at Item 18. of this annual report),

mainly in increasing capacity and improving productivity at our various production and R&D sites.

Our principal acquisitions, capital expenditures and divestitures in 2023 , 2024 and 2025 are described in Notes D.1. and D.2.

(“Changes in the scope of consolidation”), D.3. (“Property, plant and equipment”) and D.4. (“Goodwill and other intangible

assets”) to our consolidated financial statements, included at Item 18. of this annual report. For associated commitments, and

in particular future contingent milestone payments, refer to Notes D.18 and D.21. to our consolidated financial statements,

which provide disclosures about liabilities related to business combinations and our principal research and development

collaboration agreements, respectively.

As of December 31, 2025 , our firm commitments in respect of future capital expenditures amounted to € 926 million. The

principal locations involved are: for medicines, the industrial facilities at Frankfurt (Germany); Le Trait, Lyon, Aramon, Sisteron

and Vitry (France); Cambridge (US ) ; Geel (Belgium); Waterford (Ireland); Anagni and Scoppito (Italy); Shuand Xi (China); and for

vaccines, the facilities at Swiftwater (US); Toronto (Canada); Marcy-l’Étoile, Neuville-sur-Saône and Val-de-Reuil (France); and

Tuas (Singapore).

In the medium term and assuming no changes in the scope of consolidation, we expect to invest on average approximately

€1.75 billion a year in property, plant and equipment. We believe that our own cash resources and the undrawn portion of our

existing credit facilities will be sufficient to fund these expenditures.

Our principal ongoing capital expenditures are described below.

Medicines

Our Medicines industrial operations are organized through end-to-end clusters.

We have four dedicated biotechnology hubs: Paris/Lyon (France), Frankfurt (Germany), Geel (Belgium) and the Boston area

(US). Exploiting innovative techniques, including cell and microbiological culture and the development of viral vectors, our

biotechnology operations call for highly specific knowledge and expertise backed by dedicated production platforms to

support global product launches.

We also have end-to-end clusters with chemistry, pharmaceutical and injectable sites organized through a network of regional

and local industrial sites, supporting growth in those markets. A dedicated Launch Sites cluster has been implemented, from

API manufacturing to finished goods packaging (Sisteron, Aramon, Ambarès, Scoppito). The Frankfurt facility is our principal

site for the manufacture of diabetes treatments. Also in 2024, we announced major investments in the production of insulin

APIs, at new facilities in Frankfurt (Germany) and Beijing (China).

— Year ended December 31, 2024 compared with year ended December 31, 2023 ” of our annual report on Form 20-F filed

on February 13, 2025 .

A. Operating results

A.1. Significant operating information

A.1.1. 2025 Overview

2025 Business Developments

In 2025 , Sanofi introduced the “ Take the Lead ” strategy to accelerate transformative impact for patients, healthcare systems,

and society, reinforcing its position as an R&D-driven, AI-powered biopharma company committed to improving people's lives

and delivering compelling growth. For further information about our strategy, refer to “Item 4. Information on the Company

— B. Business Overview — B.1. Strategy.” Other significant events of the year are described below.

During the meeting of the Board of Directors on January 29, 2025, the Board authorized Sanofi to repurchase an aggregate

amount of the Company's own shares not exceeding €5 billion, under the terms and conditions set by the General Meeting of

April 30, 2024 in its 19th resolution. Pursuant to this authorization, Sanofi entered into a share buyback agreement with its

historical shareholder L'Oréal on February 2, 2025 for the acquisition of 2.34% of Sanofi’s share capital, equivalent to

29,556,650 shares, for a total repurchase price of approximately €3 billion, representing a price of €101.50 per share. Following

the buyback, these shares were canceled during 2025 (see Note D.15.1. Share capital to our consolidated financial statements

included at Item 18. of this annual report) . In addition, on February 6, 2025 Sanofi entered into a mandate with an investment

services provider to repurchase its own shares for a maximum aggregate amount of €2 billion between February 7, 2025 and

December 31 , 20 2 5 . The share buyback program had been executed in full by the end of 2025.

As part of its Euro Medium Term Note program, Sanofi carried out two bond issues in the first half of 2025. On March 5, a first

issue of €1.5 billion was completed, comprising €850 million of floating-rate bonds (3-month Euribor + 0.300%) maturing in

March 2027, and €650 million of fixed-rate bonds (2.75% per annum) maturing in March 2031. On June 17, a second issue of

€1.5 billion was completed, consisting of two tranches of €750 million each: one at a fixed rate of 2.625% per annum, maturing in

June 2029, and the other at a fixed rate of 3.00% per annum maturing in June 2032. Sanofi will use the net proceeds from the

issuance of these bonds for general corporate purposes.

On April 30, 2025, Sanofi announced the closing of the transaction with Clayton, Dubilier & Rice (CD&R) relating to Sanofi’s

consumer healthcare business, Opella. In accordance with the terms announced on February 19, 2025, Sanofi has transferred a

controlling stake in Opella to CD&R. Sanofi retains a 48.2% equity interest in the associate OPAL JV Co, which indirectly holds

100% of Opella. Bpifrance holds a minority stake of 1.8% and is represented on Opella’s Board of Directors. As a result of the

transaction, Sanofi recognized a net gain of €2.6 billion, reported within the line item Net income from discontinued operations

in the consolidated income statement. Sanofi received total net cash proceeds of €10.4 billion, presented within the line item Net

cash inflow from the Opella transaction in the statement of cash flows.

On May 22, 2025, Sanofi announced that it had entered into an agreement to acquire Vigil Neuroscience, Inc. (Vigil) , a publicly

traded clinical-stage biotechnology company focused on developing novel therapies for neurodegenerative diseases. This

acquisition in neurology, one of Sanofi’s four strategic disease areas, enhances Sanofi’s early-stage pipeline and includes

VG-3927, which will be evaluated in a phase 2 clinical study in Alzheimer’s disease. VG-3927 is an oral small molecule TREM2

agonist. Activating TREM2 is expected to enhance the neuroprotective function of microglia in Alzheimer’s disease. Under the

terms of a share purchase agreement (including the exclusive right of first negotiation for an exclusive license to VG-3927 or for

SANOFI FORM 20-F 2025 59

PART I
ITEM 5. Operating and Financial Review and Prospects

transfer of the rights to research, develop, manufacture, and commercialize VG-3927) entered into by Sanofi and Vigil in June

2024 for an amount of $40 million , Sanofi already held an equity interest in Vigil, representing approximately 12% of Vigil’s share

capital. That equity interest was remeasured through Other comprehensive income . VGL101, Vigil’s second molecule program,

was not acquired by Sanofi. On August 5, 2025, Sanofi acquired all outstanding common shares of Vigil for $8.00 per share in

cash at closing. Based on $8.00 per share, the total equity value of Vigil represents approximately $470 million (on a fully diluted

basis).

On May 27, 2025, Sanofi announced the completion of its acquisition of 100% of Dren-0201, Inc. , a subsidiary of the privately held

clinical-stage biopharmaceutical company Dren Bio, Inc. (Dren Bio), further to a definitive agreement signed on March 19, 2025.

The acquired entity owns DR-0201, a targeted bispecific antibody developed by Dren Bio. DR-0201, now designated SAR448501,

engages myeloid cells for robust B-cell depletion, as demonstrated in preclinical and early-stage clinical study data. Sanofi

acquired Dren-0201, Inc. for an upfront payment of €539 million, supplemented by potential milestone payments of up to

€1.2 billion subject to the achievement of development and commercialization objectives.

On July 18, 2025, Sanofi announced the completion of its acquisition of Blueprint Medicines Corporation (Blueprint) . The

acquisition adds a market-available medicine, Ayvakit/Ayvakyt (avapritinib), to Sanofi’s portfolio along with a promising pipeline,

and specialist expertise in the rare immune system disorder systemic mastocytosis (SM) and other diseases associated with the

KIT gene. The acquisition includes elenestinib, a next-generation medicine for SM, as well as BLU-808, a highly potent and

selective oral wild-type KIT inhibitor that has the potential to treat a broad range of diseases in immunology. Under the terms of

the acquisition, Sanofi paid $129.00 per share in cash at closing, representing an equity value of approximately $9.1 billion on a

fully diluted basis. Blueprint shareholders also received one non-tradeable and non-transferable contractual contingent value

right (CVR) per share, which entitles the holders thereof to receive two potential milestone payments of $2.00 and $4.00 per

CVR on the attainment of future development and regulatory milestones within the applicable milestone period, respectively, for

SAR449028 (formely known as BLU-808) . The total equity value of the transaction, including potential CVR payments,

represented approximately $9.5 billion on a fully diluted basis. With the acquisition of Blueprint, Sanofi gained an established

presence among allergists, dermatologists, and immunologists, which is expected to strengthen our ability to advance our rapidly

growing immunology pipeline.

On July 22, 2025, Sanofi announced the signing of a definitive agreement to acquire Vicebio Ltd (Vicebio) , a privately held

biotechnology company based in London, UK, specializing in the development of next-generation respiratory vaccines. Under

the terms of the agreement, Sanofi was to acquire all of Vicebio’s outstanding shares for an upfront payment of $1.15 billion,

supplemented by potential milestone payments of up to $450 million, contingent upon the achievement of development and

regulatory objectives. This acquisition provides Sanofi with an early-stage combination vaccine candidate against respiratory

syncytial virus (RSV) and human metapneumovirus (hMPV), as well as innovative molecular clamp technology, which enables the

quicker development of fully liquid combination vaccines that can be stored at standard refrigeration temperatures (2-8°C). After

obtaining all necessary regulatory approvals, the acquisition was consummated on December 4, 2025.

On September 24, 2025, Sanofi Ventures announced an additional $625 million multi-year capital commitment from Sanofi,

increasing its total assets under management to over $1.4 billion. This new commitment to the evergreen venture fund builds on

more than a decade of investing in innovative biotech and digital health companies that align with Sanofi’s long-term growth

ambitions.

On October 28, 2025, Sanofi announced that it had successfully placed its $3 billion bond issue across five tranches, including

fixed and floating rate notes maturing between November 2027 and November 2032, with interest rates ranging from 3.75% to

4.20%. The notes were issued under Sanofi’s shelf registration statement filed with the SEC on April 4, 2024, and the net

proceeds will be used for general corporate purposes.

On December 19, 2025, Sanofi entered into an agreement with the US government aimed at reducing the cost of medications for

American patients while strengthening the US role in bioproduction and pharmaceutical innovation. This voluntary and

confidential agreement addresses the four requests made by President Trump in letters sent to pharmaceutical manufacturers on

July 31, 2025. Specifically, Sanofi commits to aligning the Medicaid prices of certain medications with those in other high-income

countries, expected to result in an average reduction of 61% for certain treatments (for diabetes, cardiovascular diseases,

neurological diseases, and cancer). Sanofi will also offer direct access to patients through TrumpRx.gov with potential savings of

up to 70%. In return, Sanofi is receiving a three-year period free from Section 232 tariffs on products imported by Sanofi into the

US, while reaffirming its $20 billion investment in its US manufacturing capabilities. T his agreement is expected to have no

material impact on Sanofi's growth strategy or financial outlook during the period covered.

On December 24, 2025, Sanofi announced that it had entered into an agreement to acquire Dynavax Technologies Corporation

(Dynavax) , a publicly traded vaccines company with (i) a marketed adult hepatitis B vaccine (HEPLISAV-B), currently marketed in

the US, and (ii) a differentiated shingles vaccine candidate (Z-1018), currently in Phase 1/2 clinical development. Under the terms

of the merger agreement, Sanofi will commence a cash tender offer to acquire all outstanding shares of Dynavax for $15.50 per

share in cash, reflecting a total equity value of approximately $2.2 billion. Subject to the satisfaction or waiver of customary

closing conditions, the acquisition is expected to close in the first quarter of 2026.

ITEM 5. Operating and Financial Review and Prospects

2025 Financial results

For further information about the biopharma products we sell, and about our research and development portfolio, refer

to “Item 4. Information on the Company — B. Business Overview.”

Our net sales for 2025 amounted to €43,626 million, an increase of 6.2% from 2024 . At constant exchange rates (CER) (1) , net sales

rose by 9.9% , driven mainly by strong performances for Dupixent and increased sales of ALTUVIIIO.

Net income attributable to equity holders of Sanofi amounted to € 7,813 million for 2025 , compared with € 5,560 million in

2024 , a € 2,253 million increase. Earnings per share was € 6.40 in 2025 , compared with € 4.44 in 2024 . Business net income (2)

was € 9,555 million, up 7.2 % on 2024 , while business earnings per share (Business EPS (2) ) was 10.0% higher than in 2024 at €7.83 .

At the Annual General Meeting on April 29, 2026 , we will ask our shareholders to approve a dividend of € 4.12 per share for the

2025 financial year, representing a payout of 52.6 % of our business net income per share (see “— B.2. Consolidated balance

sheet and debt.”).

A.1.2. Impacts of competition from generics and biosimilars

Some of our flagship products continued to suffer sales erosion in 2025 under the impact of competition from generics and

biosimilars. We do not believe it is possible to state with certainty what level of net sales would have been achieved in the

absence of generic competition. A comparison of our consolidated net sales for the years ended December 31, 2025 and 2024

(see “— A.2. Results of Operations — Year Ended December 31, 2025 Compared with Year Ended December 31, 2024 ” below)

for the main products affected by generic and biosimilar competition shows a year-on-year loss of € 353 million of net sales on

a reported basis. However, other parameters can also contribute to the loss of sales, such as a fall in the average selling price of

certain products.

The table below sets forth the change by product.

(€ million)	2025	2024	Change on a reported basis	Change on a reported basis (%)
Aprovel Europe	71	73	(2)	-2.7 %
Lantus Europe	297	340	(43)	-12.6 %
Lovenox Europe	455	567	(112)	-19.8 %
Plavix Europe	88	91	(3)	-3.3 %
Aubagio Europe	67	152	(85)	-55.9 %
Mozobil Europe	8	39	(31)	-79.5 %
Aubagio United States	135	187	(52)	-27.8 %
Mozobil United States	4	12	(8)	-66.7 %
Aprovel Japan	5	11	(6)	-54.5 %
Plavix Japan	11	22	(11)	-50.0 %
Total	1,141	1,494	(353)	-23.6 %

We expect the erosion caused by generic competition to continue in 2026 , with a negative impact on our net income. The

products likely to be impacted in 2026 include those that already faced generic competit ion in 2025 , but whose sales can

reasonably be expected to be subject to further sales erosion in 2026 (see products listed in the table above). In addition, we

have experienced generic competition for Aubagio in the US since March 2023 and in Europe since October 2023, with an

intensification since 2024. The same pattern occurred for Mozobil with generic competition in the US since July 2023, and in

Europe since early 2024.

In 2025 , aggregate consolidated net sales of those products in Europe, the US and Japan were €1,141 million; this comprised

€986 million in Europe, €139 million in the US and €16 million in Japan . The negative impact on our 2026 net sales is likely to

represent a substantial portion of those sales, but the actual impact will depend on a number of factors, such as the impact of

generics and biosimilars on sales of our molecules, but also the market entry of generics of other molecules that are in

competition with our products.

In China, the authorities have implemented a range of healthcare cost containment measures, including the Volume Based

Procurement (VBP) reverse auction that particularly impacts our insulin-based products, Plavix, Aprovel, and Lovenox (see also

“Item 4. Information on the Company — B. Business Overview — B.5.4. Pricing & Reimbursement”). A large number of molecules

were selected to submit tenders under successive waves of the VBP program, with the successful bidders being awarded a high

level of market share in return for offering lower prices. The recent eleventh round of VBP results remained very unfavorable to

multinational companies. Domestic generic companies confirmed the existing trend, and won the main bids due to further

aggressive price reductions.

(1) From 2024, Net sales excludes sales of Consumer Healthcare products, reclassified within Net income from discontinued operations for the years

presented.

in 2025 ); Genzyme (€51 million in 2025 and €152 million in 2024 ); Bioverativ (€590 million in 2025 and €630 million in 2024 );

Kadmon (€157 million in 2025 and €164 million in 2024 ); and Provention (€205 million in 2025 and €214 million in 2024 ).

In order to isolate the purchase accounting effects of all acquisitions and the impact of certain other items, we use a non-IFRS

financial measure that we refer to as “Business net income” (see definition and discussion of reconciliation to the IFRS financial

measure Net income attributable to equity holders of Sanofi in “— A.1.5. Segment Information and Business Net Income —

3/ Business Net Income” below).

A.1.4. Sources of revenues and expenses

Revenues: Revenue arising from the sale of goods is presented in the income statement within Net sales . Net sales comprise

revenue from sales of medicines, vaccines and active ingredients (1) , net of sales returns, of customer incentives and discounts,

and of certain sales-based payments paid or payable to the healthcare authorities. Returns, discounts, incentives and rebates are

recognized in the period in which the underlying sales are recognized, as a reduction of sales revenue. See Note B.13.1. to our

consolidated financial statements included at Item 18. of this annual report. We sell biopharma products directly, through

alliances, and by licensing arrangements throughout the world. When we sell products directly, we record sales revenues as part

of our consolidated net sales. When we sell products through alliances, the revenues reflected in our consolidated financial

statements are based on the contractual arrangements governing those alliances. For more information about our alliances,

see “— A.1.7. Financial Presentation of Alliances” below.

Other revenues: all revenue that falls within the scope of IFRS 15 but does not relate to sales of Sanofi products is shown in this

line item. It mainly comprises (i) royalties received from licensing intellectual property rights to third parties; (ii) VaxServe sales of

products sourced from third-party manufacturers; and (iii) revenue received under agreements for Sanofi to provide

manufacturing services to third parties. Royalties received under licensing arrangements are recognized over the period during

which the underlying sales are recognized. VaxServe's operations include the distribution within the US of vaccines and other

products manufactured by third parties.

Other revenues is also used to recognize revenues generated from the manufacturing of Consumer Healthcare products on

behalf of Opella entities. Until April 30, 2025, Opella entities were within the scope of discontinued operations (see Note B.7. to

our consolidated financial statements included at Item 18. of this annual report). With effect from May 1, 2025, Opella entities are

treated as related parties in accordance with IAS 24 (see Note D.6. to our consolidated financial statements included at Item 18.

of this annual report).

In addition, Other revenues includes revenues associated with Consumer Healthcare operations not transferred on the effective

date of loss of control of Opella. These comprise primarily, but not exclusively, Consumer Healthcare activities that were not

transferred on the effective date of loss of control of Opella, primarily (i) hospital sales of Opella products in China, the transfer of

which will be finalized no earlier than 2028 after a transitional period required to complete the transfer plan agreed with Sanofi in

the context of public tendering arrangements; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to

hold the capital (Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in

connection with the separation, the parties reserving the right to discuss the transfer of that entity during the term of the

distribution agreement); and (iii) sales of the Gold Bond product range, which are continuing in the US through the retained

subsidiary Gold Bond LLC (holder of the associated worldwide property rights).

Cost of Sales . Our cost of sales consists primarily of the cost of purchasing raw materials and active ingredients, labor and other

costs relating to our manufacturing activities, packaging materials, payments made under licensing agreements and distribution

costs. We have license agreements under which we manufacture, sell and distribute products that are patented by other

companies. When we pay royalties, we record them in Cost of sales .

Operating Income . Our operating income reflects our revenues, our cost of sales and the remainder of our operating expenses,

the most significant of which are research and development expenses and selling and general expenses. For our operating

segment, we also measure our results of operations through an indicator referred to as “Business Operating Income,” which we

describe below under “— A.1.5. Segment Information and Business Net Income — 2/ Business Operating Income.”

A.1.5. Segment information and Business net income

1/ Segment information

In accordance with IFRS 8 (Operating Segments), the segment information reported by Sanofi is prepared on the basis of internal

management data provided to our Chief Executive Officer, who is the chief operating decision maker of Sanofi. The operating

segment disclosures required under IFRS 8 are provided in Notes B.26. and D.35. to our consolidated financial statements

included at Item 18. of this annual report.

T he segment information presented by Sanofi consists of a single operating segment: Biopharma.

62 SANOFI FORM 20-F 2025

PART I
ITEM 5. Operating and Financial Review and Prospects

The Biopharma operating segment comprises commercial operations and research, development and production activities

relating to the Specialty Care, General Medicines and Vaccines franchises plus support and corporate functions, for all

geographical territories. It also includes revenues generated from the manufacture of Consumer Healthcare products invoiced to

Opella Healthcare SAS (Opella), which constitutes a related party with effect from April 30, 2025, the deconsolidation date,

corresponding to the closing of Sanofi's sale of a controlling stake of approximately 50% in Opella to Clayton, Dubilier & Rice

(CD&R) (for more information, see “Item 4. Information on the Company — B. Business overview — B.3 Opella”). Those revenues,

which before the deconsolidation date represented intragroup transactions classified within continuing operations, are

presented within Other revenues in the income statement. The Biopharma operating segment also includes the purchase price

of Biopharma products manufactured by Opella.

The “Other” category comprises primarily, but not exclusively, Consumer Healthcare activities not transferred on the effective

date of loss of control of Opella. These are primarily (i) hospital sales of Opella products in China, the transfer of which will be

finalized no earlier than 2028; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to hold the capital

(Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in connection with

the separation, the parties reserving the right to discuss the transfer of that entity during the term of the distribution agreement);

and (iii) sales of the Gold Bond product range, which are continuing in the United States through the retained subsidiary Gold

Bond LLC (holder of the associated worldwide property rights).

2/ Business operating income (non-IFRS financial measure)

We report segment results on the basis of “Business operating income.” This non-IFRS indicator is used internally by Sanofi’s chief

operating decision maker to measure the performance of our operating segment and to allocate resources. For a definition of

“Business operating income”refer to Note D.35. to our consolidated financial statements included at Item 18. of this annual report.

“Business operating income” is a non-IFRS financial measure and is reconciled with IFRS Operating income. In 2025 , Operating

income amounted to €6,344 million, versus €7,252 million for 2024 , and our “Business operating income” amounted to

€12,149 million, versus €11,343 million in 2024 . The reconciliation between these two measures is presented in the table below.

Because our “Business operating income” is not a standardized measure, it may not be directly comparable with the non-IFRS

financial measures of other companies using the same or similar non-IFRS financial measures. Although management uses this

non-IFRS measure to set goals and measure performance, it has no standardized meaning prescribed by IFRS. This non-IFRS

measure is presented solely to permit investors to more fully understand how Sanofi’s management assesses underlying

performance. This non-IFRS measure is not, and should not be viewed as, a substitute for IFRS measures, and should be viewed in

conjunction with IFRS measures of our performance and financial position. Consequently, there may be limitations on the

usefulness of this measure to investors.

multiple sclerosis, reflecting the reduced probability of approval arising from the negative PERSEUS phase 3 study results in Primary Progressive Multiple

Sclerosis (PPMS) and recent exchanges with the FDA and EMA on Secondary Progressive Multiple Sclerosis (SPMS). For 2024, this line includes a net

impairment charge of € 248 million, mainly due to (i) recognition of impairment losses of € 640 million against various research and development projects

(including a €239 million loss resulting from the decision taken in February 2025 to discontinue a Phase 3 clinical study investigating a vaccine

candidate to prevent invasive E.coli disease), partially offset by (ii) impairment loss reversals recognized in connection with the disposals of the ProXTen

platform and Enjaymo, for € 225 million and € 167 million respectively.

(e) Excludes (i) restructuring costs and (ii) other adjustments attributable to non-controlling interests.

(f) Mainly joint ventures.

3/ Business net income (non-IFRS financial measure)

Sanofi also presents “Business net income”, a non- IFRS financial measure that is not included in our primary financial statements.

The IFRS measure most directly comparable to “Business net income” is Net income attributable to equity holders of Sanofi ,

which amounted to € 7,813 million for 2025 , versus € 5,560 million for 2024 , representing an increase of 40.5% . “Business net

income” amounted to €9,555 million for 2025 versus €8,912 million for 2024 , representing an increase of 7.2% . “ Business net

income” for 2025 represents 21.9% of our net sales, compared with 21.7% in 2024 .

(a) In 2025, this line includes €2.6 billion related to the net gain on the Opella divestment, recognized on the date of loss of control (refer to Note D.1.).

(b) For 2025, this line mainly comprises a €1,663 million impairment loss recognized on tolebrutinib, a drug candidate in the registration phase targeting

multiple sclerosis, reflecting the reduced probability of approval arising from the negative PERSEUS phase 3 study results and recent exchanges with

the FDA and EMA. For 2024, this line includes a net impairment charge of € 248 million, mainly due to (i) recognition of impairment losses of € 640 million

against various research and development projects (including a €239 million loss resulting from the decision taken in February 2025 to discontinue a

Phase 3 clinical study investigating a vaccine candidate to prevent invasive E.coli disease), partially offset by (ii) impairment loss reversals recognized in

connection with the disposals of the ProXTen platform and Enjaymo, for € 225 million and € 167 million respectively.

(c) This line includes an impact attributable to non-controlling interests, related to a remeasurement of contingent consideration within a subsidiary of

Sanofi: €14 million expense in 2025 and €31 million expense in 2024.

(d) This line corresponds to the financial expense arising from remeasurement of the financial liability recognized in the balance sheet to reflect estimated

future royalties on sales of Beyfortus in the US.

(e) In 2025, this line includes the €310 million share of the losses of the associate OPAL JV Co (accounted for under the equity method since May 1, 2025,

see Note D.1.) attributable to the equity holders of Sanofi; that amount includes the effects of the purchase price allocation, and of related fair value

adjustments to the identifiable assets and liabilities (mainly intangible assets and inventories). This line also includes the share of profits/losses arising

from the equity-accounted investment in EUROAPI, including an impairment loss taken against the equity interests based on the quoted market price:

€2.27 as of December 31, 2025 and €2.88 as of December 31, 2024.

(f) Corresponds to the reconciliation between basic earnings per share (IFRS) and business earnings per share (non-IFRS): sum total of reconciling items

divided by the weighted average number of shares outstanding.

We define “Business net income” as Net income attributable to equity holders of Sanofi determined under IFRS, excluding the

following items:

• net income from discontinued operations, including Opella;

• amortization and impairment losses charged against intangible assets (other than software and other rights of an industrial or

operational nature);

• fair value remeasurements of contingent consideration relating to business combinations (IFRS 3), or to divestments of

operations meeting the definition of a business;

• expenses arising from the remeasurement of inventories following business combinations (IFRS 3) or acquisitions of groups of

assets that do not constitute a business within the meaning of paragraph 2b of IFRS 3;

• restructuring costs and similar items (presented within the line item Restructuring costs and similar items ) ;

• other gains and losses (including gains and losses on major divestments), presented within the line item Other gains and

losses, and litigation ;

• other costs and provisions related to litigation (presented within the line item Other gains and losses, and litigation );

• (income)/expenses related to financial liabilities accounted for at amortized cost and subject to periodic remeasurement in

accordance with paragraph B5.4.6 of IFRS 9 (Financial Instruments);

• tax effects related to the items listed above as well as effects of major tax disputes;

64 SANOFI FORM 20-F 2025

PART I
ITEM 5. Operating and Financial Review and Prospects

• the share of profits/losses from investments accounted for using the equity method, except for t he share of profits/losses

from investments accounted for using the equity method, to the extent that this relates (i) to joint ventures or (ii) to associates

with which Sanofi has entered into R&D agreements and/or whose operations are managed as an integral part of Sanofi’s

business activities ; and

• the portion attributable to non-controlling interests of the items listed above.

We also report “Business earnings per share” (“Business EPS”), a non-IFRS financial measure we define as “Business net income”

divided by the weighted average number of shares outstanding. “Business EPS” was €7.83 for 2025 , compared with €7.12 for

2024 (up 10.0% ), based on an average number of shares outstanding of 1,220.4 million for 2025 and 1,251.4 million for 2024 .

The most significant reconciling items between “Business net income” and Net income attributable to equity holders of Sanofi

relate to (i) the purchase accounting effects of our acquisitions of groups of assets and business combinations, particularly the

amortization and impairment of intangible assets (other than software and other rights of an industrial or operational nature);

(ii) the impacts of restructuring actions or transactions regarded as non-recurring, where the amounts involved are particularly

significant; (iii) remeasurements recognized through profit or loss in respect of (a) amounts receivable in respect of business

divestments and accounted for at fair value, (b) liabilities arising from business combinations (IFRS 3) and accounted for at fair

value, and (c) liabilities accounted for at amortized cost and subject to periodic remeasurement under IFRS 9; and (iv) net income

from discontinued operations, including Opella. We believe that excluding those impacts enhances an investor’s understanding

of our underlying economic performance, because it gives a better representation of our recurring operating performance.

We believe that eliminating charges related to purchase accounting effects (particularly amortization and impairment of some

intangible assets) enhances comparability of our ongoing operating performance relative to our peers. Those intangible assets

(principally rights relating to research and development, technology platforms and commercialization of products) are accounted

for in accordance with IAS 38 (Intangible Assets) and IFRS 3 (Business Combinations).

We also believe that eliminating the other effects of business combinations (such as the incremental cost of sales arising from the

workdown of acquired inventories remeasured at fair value in business combinations) gives a better understanding of our

recurring operating performance.

Eliminating restructuring costs and similar items enhances comparability with our peers because those costs are incurred in

connection with reorganization and transformation of Sanofi's programs, integration or separation as part of material deals.

We believe that eliminating the effects of transactions that we regard as non-recurring and that involve particularly significant

amounts (such as major gains and losses on disposals, and costs and provisions associated with major litigation and other major

non-recurring items) improves comparability from one period to the next.

Finally, remeasurements recognized in profit or loss during the period in respect of (i) assets or liabilities accounted for at fair

value and recognized in the balance sheet in connection with business acquisitions or divestments or (ii) liabilities accounted for

at amortized cost and subject to periodic remeasurement, generally determined on the basis of revised sales forecasts, are not

reflective of our operating performance.

In addition, “Business net income” excludes net income from the Opella discontinued operation, the results of which have been

presented separately in the consolidated income statement since October 2024. Under IFRS 5 (Non-Current Assets Held for Sale

and Discontinued Operations), a discontinued operation is defined as a component of an entity that has been disposed of or is

classified as held for sale, and represents a separate major line of business. With effect from October 2024, “Business net income”

from continuing operations is used by management to measure Sanofi’s financial performance on an ongoing basis. We believe

that providing a performance measure aligned with our management approach is useful for investors and analysts.

We remind investors, however, that “Business net income” should not be considered in isolation from, or as a substitute for, Net

income attributable to equity holders of Sanofi reported in accordance with IFRS. In addition, we strongly encourage investors

and potential investors not to rely on any single financial measure but to review our financial statements, including the notes

thereto, carefully and in their entirety.

We compensate for the material limitations described above by using “Business net income” only to supplement our IFRS

financial reporting and by ensuring that our disclosures provide sufficient information for a full understanding of all adjustments

included in “Business net income.”

Because our “Business net income” and “Business EPS” are not standardized measures, they may not be directly comparable with

the non-IFRS financial measures of other companies using the same or similar non-IFRS financial measures.

A.1.6. Presentation of net sales

In the discussion below, we present our consolidated net sales for 2025 and 2024 . We analyze our net sales by various categories

including medicines, vaccines, business, and geographical region. In addition to reported net sales, we analyze non-IFRS financial

measures designed to isolate the impact on our net sales of currency exchange rates and changes in the structure of our group.

When we refer to changes in our net sales at constant exchange rates (CER), that means that we have excluded the effect of

exchange rates by recalculating net sales for the relevant period using the exchange rates that were used for the previous period.

ITEM 5. Operating and Financial Review and Prospects

A.1.7. Financial presentation of alliances

We have entered into a number of alliances for the development, co-promotion and/or co-marketing of our products. The two

principal alliances are with Regeneron Pharmaceuticals, Inc. for the development and commercialization of therapeutic

antibodies including Dupixent and Kevzara, and with AstraZeneca for the development and commercialization of Beyfortus

(nirsevimab) for RSV prevention.

Specifically with respect to Regeneron, in 2014 and 2020, Sanofi and Regeneron amended the Investor Agreement entered into

by the two companies in 2007. Under the terms of the amendments, Sanofi accepted various restrictions, including “standstill”

provisions that contractually prohibit Sanofi from seeking to directly or indirectly exert control of Regeneron or acquiring more

than 30% of Regeneron’s capital stock (consisting of the outstanding shares of common stock and the shares of Class A stock).

This prohibition remains in place until the earlier of (i) the later of the fifth anniversaries of the expiration or earlier termination of

the Zaltrap collaboration agreement with Regeneron (related to the development and commercialization of Zaltrap) or the

collaboration agreement with Regeneron on monoclonal antibodies, each as amended or (ii) other specified events.

For detailed information on the terms, financial arrangements, and accounting treatment of these alliances, see Note C “Principal

alliances” to our consolidated financial statements included at Item 18. of this annual report.

A.1.8. Impact of exchange rates

We report our consolidated financial statements in euros. Because we earn a significant portion of our revenues in countries

where the euro is not the local currency, our results of operations can be significantly affected by exchange rate movements

between the euro and other currencies.

We experience these effects even though certain of these countries do not account for a large portion of our net sales. In 2025 ,

we earned 50.8% of our net sales in the United States . An increase in the value of the US dollar against the euro has a positive

impact on both our revenues and our operating income. A decrease in the value of the US dollar against the euro has a negative

impact on our revenues, which is not offset by an equal reduction in our costs and therefore negatively affects our operating

income. A variation in the value of the US dollar has a particularly significant impact on our operating income, which is higher in

the United States than elsewhere.

For a description of arrangements entered into to manage operating foreign exchange risks as well as our hedging policy,

see “Item 11. Quantitative and Qualitative Disclosures about Market Risk,” and “Item 3. Key Information — D. Risk Factors — Risks

Related to Financial Markets — Fluctuations in currency exchange rates could adversely affect our results of operations and

financial condition.”

A .1.9. Divestments

On April 30, 2025, Sanofi and CD&R closed the Opella Transaction following the signature of the share purchase agreement (SPA)

on February 18, 2025. The Opella T ransaction generated a net cash inflow of €10.4 billion , presented within the line item Net cash

inflow from the Opella transaction in the statement of cash flows. For more information on the Opella Transaction, see " — A.1.1.

2025 Overview " and Note D.1.1.1. to our consolidated financial statements included at Item 18 of this annual report.

On November 29, 2024, Sanofi entered into a definitive agreement with Recordati for the sale of Sanofi's global rights to Enjaymo

and the transfer of specific employees. Under this agreement, Sanofi received an upfront payment of $825 million and will be

eligible for milestone payments of up to $250 million based on sales.

Fo r further details about the divestments mentioned above, see Note D.1. to our consolidated financial statements included

at Item 18. of this annual report.

A.1.10. Acquisitions

In the year ended December 31, 2025, Sanofi:

• entered into an agreement to acquire Dynavax; and

• completed the acquisitions of Vicebio, Blueprint, DR-0201 and Vigil.

For further information about these acquisitions see “— A.1.1. 2025 Overview” and Note D.1. to our consolidated financial

statements included at Item 18. of this annual report.

In the year ended December 31, 2024, Sanofi completed the acquisition of Inhibrx , adding SAR447537 (formerly INBRX-101) to

Sanofi’s rare disease pipeline. The impact of this acquisition, as reflected within the line item Acquisitions of consolidated

undertakings and investments accounted for using the equity method in the consolidated statement of cash flows, is a net

cash outflow of $2,035 million .

For further information about the Inhibrx acquisition, see “Item 4. Information on the Company – A. History and development of

A.1.11. Critical accounting and reporting policies

Our consolidated financial statements are affected by the accounting and reporting policies that we use. Certain of our

accounting and reporting policies are critical to an understanding of our results of operations and financial condition, and in some

cases the application of these critical policies can be significantly affected by the estimates, judgments and assumptions made

by management during the preparation of our consolidated financial statements. The accounting and reporting policies that we

have identified as critical to a full understanding of our results of operations and financial condition are the following:

1/ Revenue recognition

Our policies with respect to revenue recognition are discussed in Note B.13. to our consolidated financial statements included

at Item 18. of this annual report. Revenue arising from the sale of goods is presented in the income statement within Net sales .

Net sales comprise revenue from sales of medicines, vaccines, and active ingredients, net of sales returns, of customer incentives

and discounts, and of certain sales-based payments paid or payable to the healthcare authorities. In accordance with IFRS 15

(Revenue from Contracts with Customers), such revenue is recognized when Sanofi transfers control over the product to the

customer. Control refers to the ability to direct the use of, and obtain substantially all of the remaining benefits from, the

products. For the vast majority of contracts, revenue is recognized when the product is physically transferred, in accordance with

the delivery and acceptance terms agreed with the customer.

For contracts entered into by our vaccines business, transfer of control is usually determined by reference to the terms of release

(immediate or deferred) and acceptance of batches of vaccine.

As regards contracts with distributors, Sanofi does not recognize revenue when the product is physically transferred to the

distributor in case of products sold on consignment, or if the distributor acts as an agent. In such cases, revenue is recognized

when control is transferred to the end customer, and the distributor’s commission is presented within the line item Selling and

general expenses in the income statement.

We offer various types of price reductions on our products. In particular, products sold in the US are covered by various programs

(such as Medicare and Medicaid) under which products are sold at a discount. Rebates are granted to healthcare authorities, and

under contractual arrangements with certain customers. For more information on price reductions of our products, see “Item 4.

Information on the Company — B. Business Overview — B.5.4. Pricing & Reimbursement.” Some wholesalers are entitled to

chargeback incentives based on the selling price to the end customer, under specific contractual arrangements. Cash discounts

may also be granted for prompt payment. The discounts, incentives and rebates described above are estimated on the basis of

specific contractual arrangements with our customers or of specific terms of the relevant regulations and/or agreements

applicable for transactions with healthcare authorities, and of assumptions about the attainment of sales targets. We also

estimate the amount of sales returns, on the basis of contractual sales terms and reliable historical data. Discounts, incentives,

rebates and sales returns are recognized in the period in which the underlying sales are recognized within Net Sales , as a

reduction of gross sales. For additional details regarding the financial impact of discounts, incentives, rebates and sales returns,

see Note D.23. to our consolidated financial statements included at Item 18. of this annual report.

Revenues from non-Sanofi products, mainly comprising royalty income from license arrangements and sales of non-Sanofi

products by our US-based entity VaxServe, are presented within Other revenues . This line item also includes revenues arising

from the distribution of Eloctate and Alprolix under Sanofi’s agreements with Swedish Orphan Biovitrum AB (Sobi) and revenue

received under agreements for Sanofi to provide manufacturing services to third parties. Other revenues is also used to recognize

revenues generated from the manufacturing of Consumer Healthcare products on behalf of Opella entities. Until April 30, 2025,

Opella entities were within the scope of discontinued operations (see Note B.7. to our consolidated financial statements included

at Item 18. of this annual report). With effect from May 1, 2025, Opella entities are treated as related parties in accordance with

IAS 24 (see Note D.6. to our consolidated financial statements included at Item 18. of this annual report). In addition, Other

revenues includes revenues associated with Consumer Healthcare operations not transferred on the effective date of loss of

control of Opella. These comprise primarily, but not exclusively, Consumer Healthcare activities that were not transferred on the

effective date of loss of control of Opella, primarily (i) hospital sales of Opella products in China, the transfer of which will be

finalized no earlier than 2028 after a transitional period required to complete the transfer plan agreed with Sanofi in the context

of public tendering arrangements; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to hold the

capital (Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in connection

with the separation, the parties reserving the right to discuss the transfer of that entity during the term of the distribution

agreement); and (iii) sales of the Gold Bond product range, which are continuing in the US through the retained subsidiary Gold

Bond LLC (holder of the associated worldwide property rights). Finally, in the interests of consistency, Other revenues includes

revenues associated with Consumer Healthcare operations that will not be transferred on the effective date of loss of control of

Opella. For further discussion of the Other revenues line item, see “— A.1.4. Sources of revenues and expenses.”

As discussed in Note B.3. “Business combinations and transactions with non-controlling interests” to our consolidated financial

statements included at Item 18. of this annual report, business combinations are accounted for by the acquisition method.

The acquiree’s identifiable assets and liabilities that satisfy the recognition criteria of IFRS 3 (Business Combinations) are

measured initially at their fair values as at the acquisition date, except for (i) non-current assets classified as held for sale, which

are measured at fair value less costs to sell and (ii) assets and liabilities that fall within the scope of IAS 12 (Income Taxes)

and IAS 19 (Employee Benefits). Business combinations completed on or after January 1, 2010 are accounted for in accordance

with the revised IFRS 3 and IFRS 10 (Consolidated Financial Statements). In particular, contingent consideration payable to former

owners agreed in a business combination, e.g. in the form of payments upon the achievement of certain R&D milestones, is

recognized as a liability at fair value as of the acquisition date irrespective of the probability of payment. If the contingent

consideration was originally recognized as a liability, subsequent adjustments to the liability are recognized in profit or loss

(see Note D.18. to our consolidated financial statements included at Item 18. of this annual report).

3/ Impairment of goodwill and intangible assets

As discussed in Note B.6. “Impairment of property, plant and equipment, intangible assets, and investments accounted for using

the equity method” and in Note D.5. “Impairment of intangible assets and property, plant and equipment” to our consolidated

financial statements included at Item 18. of this annual report, we test our intangible assets for impairment periodically or when

there is any internal or external indication of impairment. Such indicators could include primarily but not exclusively (i) increased

market competition resulting from (for example) the introduction of a competitor’s product; (ii) earlier than expected loss of

exclusivity; (iii) increased pricing pressure; (iv) restrictions imposed by regulatory authorities on the manufacture or sale of a

product; (v) delay in the projected launch of a product; (vi) different from expected clinical study results; (vii) higher than

expected development costs or (viii) lower than expected economic performance.

We test for impairment on the basis of the same objective criteria that were used for the initial valuation. Our initial valuation and

ongoing tests are based on the relationship of the value of our projected future cash flows associated with the asset to either the

purchase price of the asset (for its initial valuation) or the carrying amount of the asset (for ongoing tests for impairment).

Significant underlying assumptions requiring the exercise of considerable judgement are applied in the future cash flow

projections used to determine the recoverability of intangible assets, including primarily but not exclusively (i) therapeutic class

market growth drivers; (ii) expected impacts from competing products (including but not exclusively generics and biosimilars);

(iii) projected pricing and operating margin levels; (iv) likely changes in the regulatory, legal or tax environment; and

(v) management’s estimates of terminal growth or attrition rates.

The recoverable amounts of intangible assets related to research and development projects are determined based on future net

cash flows, which reflect the development stage of the project and the associated probability of success of marketization of the

compound.

The projected cash flows are discounted to present value using a discount rate, which factors in the risks inherent in cash flow

projections.

Changes in facts and circumstances, assumptions and/or estimates may lead to future additional impairment losses or reversal of

impairment previously recorded.

Key assumptions relating to goodwill impairment are the perpetual growth rate, the post-tax discount rate, and operating margin .

A sensitivity analysis to the key assumptions is disclosed in Note D.5. “Impairment of intangible assets and property, plant and

equipment” to our consolidated financial statements included at Item 18. of this annual report.

4/ Pensions and post-retirement benefits

As described in Note B.23. “Employee benefit obligations” to our consolidated financial statements included at Item 18. of this

annual report, we recognize our pension and retirement benefit commitments as liabilities on the basis of an actuarial estimate of

the rights vested in employees and retirees at the end of the reporting period, net of the fair value of plan assets held to meet

those obligations. We prepare this estimate at least on an annual basis taking into account financial assumptions (such as

discount rates) and demographic assumptions (such as life expectancy, retirement age, employee turnover, and the rate of salary

increases).

We recognize all actuarial gains and losses (including the impact of a change in discount rate) immediately through equity.

Depending on the key assumptions used, the pension and post-retirement benefit expense could vary within a range of

outcomes and have a material effect on reported earnings. A sensitivity analysis to these key assumptions is set forth

in Note D.19.1. “Provisions for pensions and other benefits” to our consolidated financial statements included at Item 18. of this

annual report.

ITEM 5. Operating and Financial Review and Prospects

5/ Taxes

As discussed in Note B.22. “Income tax expense” to our consolidated financial statements included at Item 18. of this annual

report, we recognize deferred income taxes on tax loss carry-forwards and on temporary differences between the tax base and

carrying amount of assets and liabilities. We calculate our deferred tax assets and liabilities using enacted tax rates applicable for

the years during which we estimate that the temporary differences are expected to reverse. We do not recognize deferred tax

assets when it is more likely than not that the deferred tax assets will not be realized. The recognition of deferred tax assets is

determined on the basis of profit forecasts for each tax group, and of the tax consequences of the strategic opportunities

available to Sanofi.

The positions adopted by Sanofi in tax matters are based on its interpretation of tax laws and regulations. Some of those positions

may be subject to uncertainty. In such cases, Sanofi assesses the amount of the tax liability on the basis of the following

assumptions: that its position will be examined by one or more tax authorities on the basis of all relevant information; that a

technical assessment is carried out with reference to legislation, case law, regulations, and established practice; and that each

position is assessed individually (or collectively where appropriate), with no offset or aggregation between positions. Those

assumptions are assessed on the basis of facts and circumstances existing at the end of the reporting period. When an uncertain

tax liability is regarded as probable, it is measured on the basis of Sanofi’s best estimate and recognized as a liability; uncertain tax

assets are not recognized.

6/ Provisions for risks

Sanofi and its subsidiaries and affiliates may be involved in litigation, arbitration or other legal proceedings. These proceedings

typically are related to product liability claims, intellectual property rights, compliance and trade practices, commercial claims,

employment and wrongful discharge claims, tax assessment claims, waste disposal and pollution claims, and claims under

warranties or indemnification arrangements relating to business divestitures. As discussed in Note B.12. “Provisions for risks” to

our consolidated financial statements included at Item 18. of this annual report, we record a provision where we have a present

obligation, whether legal or constructive, as a result of a past event; it is probable that an outflow of resources embodying

economic benefits will be required to settle the obligation; and a reliable estimate can be made of the amount of the outflow of

resources. We also disclose a contingent liability in circumstances where we are unable to make a reasonable estimate of the

expected financial effect that will result from the ultimate resolution of the proceeding, or a cash outflow is not probable.

For additional details regarding the financial impact of provisions for risks, see Notes D.19.3. “Other provisions” and D.22. “Legal

and Arbitral Proceedings” to our consolidated financial statements included at Item 18. of this annual report.

7/ Provisions for restructuring costs

Provisions for restructuring costs include collective redundancy or early retirement benefits, compensation for early termination

of contracts, and rationalization costs relating to restructured sites. Refer to Note D.19.2. to our consolidated financial statements

included at Item 18. of this annual report.

Provisions are estimated on the basis of events and circumstances related to present obligations at the end of the reporting

period and of past experience, and to the best of management’s knowledge at the date of preparation of the financial

statements. The assessment of provisions can involve a series of complex judgments about future events and can rely heavily on

estimates and assumptions. Given the inherent uncertainties related to these estimates and assumptions, the actual outflows

resulting from the realization of those risks could differ from our estimates.

A.2.1. Net sales

Consolidated net sales for the year ended December 31, 2025 amounted to €43,626 million, 6.2% higher than in 2024 on a

reported basis. Exchange rate fluctuations had a negative effect of 3.7 percentage points overall, due mainly to adverse trends in

the US dollar against the euro. At constant exchange rates (CER), net sales rose by 9.9% , driven mainly by strong performances

for Dupixent and ALTUVIIIO.

When we refer to changes in our net sales at constant exchange rates (CER), that means we have excluded the effect of

exchange rates by recalculating net sales for the relevant period using the exchange rates that were used for the previous period,

with the exception of countries treated as hyperinflationary economies under IAS 29 (i.e. Argentina and Turkey, see Note A.4. to

our consolidated financial statements).

3/ Net sales – Biopharma segment

In 2025 , net sales for the Biopharma segment (see “— A.1.5. Segment Information and Business net income” for detailed

disclosures about our operating segment, and Note D.35. to our consolidated financial statements included at Item 18. of this

annual report) amounted to €43,626 million, up 6.2% on a reported basis and 9.9% at CER. The year-on-year reported-basis

increase of €2,545 million reflects adverse exchange rate effects amounting to €1,531 million, and the following principal effects

at CER:

• solid performances from Dupixent (net sales up €3,292 million, or 25.2 % ) and ALTUVIIIO (net sales up €529 million); and

• the launch of Ayvakit (net sales of €325 million).

Comments on the performances of our major Biopharma segment products are provided below.

New launches

ALTUVIIIO ( hemophilia A) posted net sales of €1,160 million in 2025 , up 77.6% CER, with 84.4% generated in the US. Growth

continued to be driven by patient switching from older, short half-life and extended half-life factor medicines, including Eloctate,

and from non-factor treatments. Total hemophilia A franchise sales (ALTUVIIIO + Eloctate) amounted to €1,435 million ( +42.6%

CER), representing an increase in Sanofi’s market share of factor-based treatments as well as of the overall hemophilia A market.

Nexviazyme/Nexviadyme (Pompe disease) sales were €790 million, up 21.4% year-on-year, driven by Europe ( +38.8% CER), where

the rise was explained by switches from Myozyme/Lumizyme in the eligible late-onset Pompe disease popula tion and an increase

in new patients. In the US, where sales reached €393 million, the majority of patients have now transitioned off

Myozyme/Lumizyme. Total sales for the Pompe franchise (Nexviazyme/Nexviadyme + Myozyme/Lumizyme) were €1,309 million.

Nexviazyme/Nexviadyme now account for 60.4 % of total Pompe franchise sales.

Sarclisa (multiple myeloma) reported sales of €588 million, up 28.5% CER, driven by strong growth in all three regions. Sales

reached €244 million in the US ( +27.5% CER), €174 million in Europe ( +29.9% CER), and €170 million in the Rest of the World

region ( +28.5% CER). This significant progress is being largely driven by increased use in a front-line combination treatment

setting.

Sales of Rezurock (chronic graft-versus-host disease) were €490 million in 2025 , an increase of 8.7% CER, driven by continued

growth in the US ( €425 million, +4.2% CER), where the product is becoming the standard of care in the indicated setting, and by

rapid uptake in launch countries, especially China. Globally, over 20,000 patients have been prescribed Rezurock (including

patients in early access or managed access programs) since launch, key drivers being the product's real-world efficacy,

tolerability and oral route of administration.

Ayvakit (mastocytosis) sales were €305 million. Ayvakit has been consolidated by Sanofi since mid-July 2025 following the

acquisition of Blueprint. Sales were split between the US ( €267 million) and Europe ( €36 million) with continued growth in the

number of patients treated. Annual sales reached $725 million, slightly ahead of Blueprint's expectations from earlier in the year

(estimated at $700-$720 million). Sanofi does not hold marketing rights in China but receives royalties on sales by CStone

Pharmaceuticals CO., Ltd.

Cablivi (acquired thrombotic thrombocytopenic purpura) reported 2025 sales of €271 million ( +12.0% CER), including €143 million

( +9.6% CER) in the US, driven by more patients being identified for treatment in the US and Europe and less use of the US access

program.

Xenpozyme (acid sphingomyelinase deficiency) achieved sales of €228 million in 2025 , an increase of 54.3% CER, mainly driven

by Europe where net sales rose by 93.5% CER.

Sales of Tzield (delayed onset of type 1 diabetes) amounted to €63 million, of which €59 million was generated in the US ( +19.2%

CER). Patient screenings continued to increase, driving slight growth in the number of patients treated.

Sales of Qfitlia (hemophilia A and B) totaled €9 million, all of which was generated in the US, following approval in March 2025.

Sales of Wayrilz (immune thrombocytopenia) totaled €7 million, all of which was generated in the US, following approval in August

2025.

Immunology

Dupixent generated net sales of €15,714 million in 2025 , up 20.2% on a reported basis and 25.2% at CER, driven by continuing

strong demand in the product’s approved indications: atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyposis,

eosinophilic esophagitis, prurigo nodularis, chronic spontaneous urticaria, chronic obstructive pulmonary disease, and bullous

pemphigoid . Dupixent net sales for 2025 by geography were €11,538 million ( +26.7% CER) in the US, €1,957 million (+ 20.8% CER)

in Europe, and €2,219 million ( +21.3% CER) in the Rest of the World region.

Other main medicines

Lantus sales were €1,733 million, up 10.3% CER . US sales were €808 million, up 32.1% CER, benefiting from the unavailabili ty of

competing medicines. Customer demand is now expected to normalize in 2026 . In Europe, net sales decreased by 12.4% CER; i n

the Rest of the World region, sales were up 0.8% CER, mainly due to the strategy of switching to Toujeo in China.

Toujeo sales rose by 12.0% CER to €1,345 million, led by the Rest of the World region where net sales were up 17.5% CER at

€605 million. Toujeo increased its market share, especially in basal insulins, led by China where the product’s market share now

exceeds that of Lantus.

Sales of Fabrazyme reached €1,019 million in 2025 ( +0.1% CER ), with a slight rise in the number of patients.

SANOFI FORM 20-F 2025 73

PART I
ITEM 5. Operating and Financial Review and Prospects

Plavix sales stabilized, posting growth of 3.1% CER to €910 million, mainly reflecting volume growth in China due to inclusion in the

volume-based procurement (VBP) program, partly offset by market share slowdown in the other countries within the Rest of the

World region (which represents the majority of sales at €816 million).

Lovenox sales were down 14.4 % CER at €822 million, reflecting impacts from increasing competition in Europe and the Rest of

the World region.

Cerezyme sales decreased by 3.9% CER to €695 million. Sales for the global Gaucher disease franchise (Cerezyme and Cerdelga)

reached €1,030 million.

In 2025 , sales of Alprolix amounted to €603 million, up 7.0% CER , driven by the Rest of the World region ( +26.6% CER) and the US

( +1.7% CER), due to supply sales under the collaboration with Sobi.

Net sales of Praluent for 2025 reached €526 million, up 9.3% CER , underpinned by Europe (+ 25.0% ) but partially mitigated by a

decrease in the Rest of the World region of 28.0% .

Sales of Myozyme/Lumizyme decreased by 21.0% CER in 2025 to €519 million, reflecting patient switches to

Nexviazyme/Nexviadyme as mentioned above.

Thymoglobulin sales rose by 3.7% CER to €490 million, driven by the US ( +2.9% CER) and the Rest of the World region ( +5.0%

CER).

Cerdelga sales were €335 million, up 3.0% , reflecting growth in the number of patients.

Eloctate posted sales of €275 million in 2025 , down 22.3% CER , as patients switched to ALTUVIIIO.

Sales of Aubagio were down 35.4% CER at €238 million, reflecting the loss of exclusivity in the US in March 2023 ( -24.1% CER in

2025 ), followed by the loss of exclusivity in Europe in September 2023 ( -55.9% CER in 2025 ) . Individual sales reporting for

Aubagio is anticipated to discontinue in 2026 with any remaining sales to be included in the “Others” category.

Vaccines

In 2025 , Vaccines sales were €7,936 , down 4.4% on a reported basis and 1.2% CER, reflecting lower sales of influenza vaccines.

Sales of Polio/Pertussis/Hib Vaccines and Boosters reached €2,554 million, down 4.4% CER.

Influenza, COVID-19 vaccines sales were €2,314 million, down 5.8% CER in a contracted market. Sales in Europe ( -13.1% CER ) were

impacted by price reductions in Germany, while sales in the US ( -1.9% CER) were impacted by soft vaccination rates.

Beyfortus sales reached €1,781 million, up 9.5% CER . Sales i n Europe of €601 million ( +36.1% CER) and in the Rest of World region

of €457 million ( +168.5% CER) were driven by the geographical rollout of all-infant protection. Beyfortus now protects infants in

more than 45 countries. Sales in the US were down 27.9% CER at €723 million due to a high base effect and existing inventory

levels at the beginning of the season.

Meningitis, Travel and Endemics Vaccines sales increased by 0.8% CER to €1,287 million.

4/ Net sales by geographical region

The table below sets forth our net sales for 2025 and 2024 by geographical region:

(€ million)	2025	2024	Change on a reported basis	Change at constant exchange rates
United States	22,176	19,986	+11.0%	+16.3%
Europe	9,169	9,027	+1.6%	+1.6%
Rest of the World	12,281	12,068	+1.8%	+5.6%
of which China	2,621	2,666	-1.7%	+2.0%
Total net sales	43,626	41,081	+6.2%	+9.9%

In 2025 , net sales in the United States reached €22,176 million, up 11.0% on a reported basis and 16.3% CER, driven by exceptional

performances from Dupixent ( +26.7% CER at €11,538 million) and ALTUVIIIO ( +66.5% CER at €979 million).

In Europe , net sales rose by 1.6% on a reported basis and by the same rate at CER in 2025 to €9,169 million, led by Dupixent and

Beyfortus with growth of 20.8% ( €1,957 million) and 36.1% ( €601 million), respectively.

In the Rest of the World region , net sales for 2025 increased by 1.8% on a reported basis and by 5.6% CER to €12,281 million, due

to strong performances from Dupixent ( +21.3% CER at €2,219 million) and Beyfortus ( +168.5% CER at €457 million).

A.2.2. Other income statement items

1/ Other revenues

Other revenues decreased by 3.6 % to € 3,090 million in 2025 (versus € 3,205 million in 2024 ).

The Other revenues line item includes VaxServe sales of non-Sanofi products, amounting to € 1,780 million (versus € 1,959 million

in 2024 ). It also includes sales of Opella products in markets retained by Sanofi (€ 487 million); supply sales to Opella (€ 120 million);

royalties (€ 146 million); and other services/manufacturing services (€ 557 million).

ITEM 5. Operating and Financial Review and Prospects

2/ Gross profit

Gross profit for 2025 amounted to € 33,667 million compared with € 31,081 million in 2024 , an increase of 8.3 %. Gross margin (the

ratio of gross profit to net sales) inc reased , reaching 77.2 % in 2025 , versus 75.7 % in 2024 , due to improvements in Cost of sales .

3/ Research and development expenses

R&D expenses amounted to € 7,842 million in 2025 , versus € 7,394 million in 2024 , an increase of 6.1 %, and represented 18.0 % of

our net sales in 2025 (compared with 18.0 % in 2024 ). R&D spend , excluding the 2024 one-off Sobi reimbursement following the

registration of ALTUVIIIO in Europe , increased 6.3% year-on-year, driven by strategic prioritization of key therapeutic growth

areas (in particular in immunology, rare diseases, neurology and vaccines) and wind-down costs for the discontinued E. coli sepsis

vaccine candidate, as well as new acquisitions and in‑licensing agreements completed in 2025. Oncology spend was selectively

reduced to support portfolio rebalancing to immunology.

4/ Selling and general expenses

Selling and general expenses amounted to € 9,543 million in 2025 ( 21.9 % of net sales), versus € 9,183 million in 2024 ( 22.4 % of net

sales), a 3.9% year-on-year increase. The overall increase reflects continued support for launches and newer medicines in

Specialty Care and Vaccines. However, the ratio of selling and general expenses to net sales was 0.5% lower than in 2024 ,

reflecting improved operational efficiency and leverage as Sanofi scales its commercial operations. This positive trend illustrates

Sanofi's ability to drive revenue growth while maintaining disciplined cost management, with sales growing faster than the

associated selling and general expenses. The improvement in the ratio reflects the benefits of commercial excellence initiatives,

optimized resource allocation, and economies of scale achieved across key markets and therapeutic areas.

5/ Other operating income and expenses

Other operating income amounted to € 1,231 million in 2025 (versus € 1,089 million in 2024 ), and other operating expenses

to € 5,655 million (versus € 4,382 million in 2024 ).

Other operating income includes (i) gains from asset divestments, amounting to €485 million in 2025 (versus €539 million in

2024); (ii) out-licensing income from Amvuttra , amounting to € 475 million in 2025 (versus € 186 million in 2024); and (iii) income

from Sanofi’s pharmaceutical partners, amounting to €189 million in 2025 (including €149 million from Regeneron, see Note D.26.

and Note C.1. to our consolidated financial statements included at Item 18. of this annual report ), compared with €221 million in

2024 (including €166 million from Regeneron).

Other operating expenses include €5,072 million of expenses related to Regeneron (see Note C.1. to our consolidated financial

statements included at Item 18. of this annual report ), compared with €3,955 million for 2024 .

Overall, this represented a net expense of € 4,424 million in 2025 , compared with a net expense of € 3,293 million in 2024 .

(€ million)	2025	2024	Change
Other operating income	1,231	1,089	142
Other operating expenses	(5,655)	(4,382)	(1,273)
Other operating income/(expenses), net	(4,424)	(3,293)	(1,131)

The change of € 1,131 million mainly reflects an increase in the share of profits generated by the monoclonal antibody alliance with

Regeneron under the collaboration agreement (see Note C.1. to our consolidated financial statements included at Item 18. of this

annual report), the principal factor being increased sales of Dupixent.

The net contribution of items related to Regeneron to this line item is as follows:

(€ million)	2025	2024
Income & expense related to (profit)/loss sharing under the Monoclonal Antibody Alliance	(5,455)	(4,143)
Additional share of profit paid by Regeneron towards development costs (a)	1,089	833
Reimbursement to Regeneron of selling expenses incurred	(699)	(637)
Total: Monoclonal Antibody Alliance	(5,065)	(3,947)
Other (mainly Zaltrap and Libtayo)	142	158
Other operating income/(expenses), net related to Regeneron Alliance	(4,923)	(3,789)
of which amount presented in “Other operating income”	149	166

(a) As of December 31, 2025 , the commitment received by Sanofi in respect of the additional profit share payable by Regeneron towards development

costs amounted to € 0.5 billion , compared with € 1.6 billion as of December 31, 2024 .

6/ Amortization of intangible assets

Amortization charged against intangible assets amounted to € 1,776 million in 2025 , compared with € 1,749 million in 2024 .

This increase was mainly driven by amortization of the Ayvakit intangible asset following the acquisition of Blueprint, partly offset

by some intangible assets reaching the end of their amortization periods.

PART I
ITEM 5. Operating and Financial Review and Prospects

7/ Impairment of intangible assets, net of reversals

In 2025 , this line corresponds to the recognition of net impairment losses of € 2,241 million in 2025 , and mainly comprises a €1,663

million impairment loss recognized on tolebrutinib, a drug candidate in the registration phase targeting multiple sclerosis,

reflecting the reduced probability of approval arising from the negative PERSEUS phase 3 study results and recent exchanges

with the FDA and EMA. For 2024, this line includes a net impairment charge of € 248 million, mainly due to (i) recognition of

impairment losses of € 640 million against various research and development projects (including a €239 million loss resulting from

the decision taken in February 2025 to discontinue a Phase 3 clinical study investigating a vaccine candidate to prevent invasive

E.coli disease), partially offset by (ii) impairment loss reversals recognized in connection with the disposals of the ProXTen

platform and Enjaymo, for € 225 million and € 167 million respectively.

8/ Fair value remeasurement of contingent consideration

Fair value remeasurements of contingent consideration assets and liabilities (recognized on acquisitions or disposals of

activities) represented a net expense of € 104 million in 2025 , versus a net expense of € 96 million in 2024 .

9/ Restructuring costs and similar items

Restructuring costs and similar items represented a total charge of € 1,138 million in 2025 , versus a charge of € 1,396 million in

2024 , a decrease of € 258 milli on. In 2025, this line item mainly comprised (i) costs related to the social plans announced during

the year and (ii) transaction, integration and separation costs associated with significant acquisitions or disposals (€ 312 million),

mainly related to the acquisition of Blueprint. In 2024 , restructuring and similar costs mainly comprised the impacts of (i) the

renewal of the Job Management and Career Paths (GEPP) program in France to cover the 2024 - 2026 period, including scope

extensions in the job profiles affected by transformations and (ii) a voluntary redundancy program announced in 2024 in

connection with the reorganization of R&D operations to make Sanofi a leader in immunology.

10/ Other gains and losses, and litigation

Other gains and losses, and litigation for 2025 represented a charge of € 255 million related to major litigation.

For 2024 , this line item represented a charge of €470 million , mainly comprising a provision recognized in respect of the litigation

related to Plavix (clopidogrel) in the US state of Hawaii .

11/ Operating income

Operating income amounted to € 6,344 million in 2025 , versus € 7,252 million in 2024 . The year-on-year decrease was mainly

due to an increase in net impairment losses charged against intangible assets.

12/ Financial income and expenses

Net financial expenses were € 169 million in 2025 , versus € 554 million in 2024 , a decrease of € 385 million.

The 2025 amount includes financial income of € 93 million (€ 291 million expense in 2024 ) in respect of the liability recognized in

the balance sheet for estimated future royalties on US sales of Beyfortus (see Notes C.2. and D.29. to our consolidated financial

statements included at Item 18. of this annual report).

The cost of our net debt (see the definition in “— B. Liquidity and Capital Resources” below and Note D.29. to our consolidated

financial statements included at Item 18. of this annual report ) was € 166 million in 2025 , compared with € 186 million in 2024 .

13/ Income before tax and investments accounted for using the equity method

Income before tax and investments accounted for using the equity method reached € 6,175 million in 2025 , versus

€ 6,698 million in 2024 .

14/ Income tax expense

Income tax expense represented € 1,043 million in 2025 , versus € 1,204 million in 2024 , giving an effective tax rate (IFRS) based on

consolidated net income of 16.9 % in 2025 , compared with 18.0 % in 2024 . The reduction in income tax expense was mainly due to

tax effects arising from increases in impairment of intangible assets linked to research and development projects, including tax

effects arising from the €1,663 million impairment loss charged against intangible assets related to the tolebrutinib research

program.

The effective tax rate based on business net income is a non-IFRS financial measure (see definition under “— A.1.5. Segment

information — Business Net Income” above). It is calculated on the basis of business operating income, minus net financial

expenses and before (i) the share of profit/loss from investments accounted for using the equity method and (ii) net income

attributable to non-controlling interests. We believe the presentation of this measure, used by our management, is also useful for

investors as it provides a means to analyze the effective cost of taxes on our profits excluding (i) the reconciling items described

in section A.1.5. above and (ii) non-recurring or unusual tax effects. However, it should not be seen as a substitute for the effective

tax rate based on our consolidated net income.

When calculated on business net income, our effective tax rate (non-IFRS) was 19.9% in 2025 , compared with 19.8% in 2024 . The

main factors in this year-on-year change were (i) the impact of the OECD Pillar Two model rules, which aim to ensure that large

multinationals pay a minimum level of tax on the income arising in each jurisdiction where they operate; and (ii) updates to

estimates of prior period tax liabilities following progress of reviews and closure of open issues with tax authorities in various

jurisdictions.

15/ Share of profit/(loss) from investments accounted for using the equity method

The line item Share of profit/(loss) from investments accounted for using the equity method showed a net loss of € 155 million

in 2025, including a loss of €310 million on the equity-accounted investment in the associate OPAL JV Co ( see Note D.6),

compared with a net gain of € 60 million for 2024 .

16/ Net income from continuing operations

Net income from continuing operations amounted to € 4,977 million in 2025 , compared with € 5,554 million in 2024 .

17/ Net income from discontinued operations

Due to (i) the classification of Opella's assets and liabilities as held for sale since the announcement on October 21, 2024 of the

opening of exclusive negotiations with CD&R for the transfer of those assets and liabilities and (ii) the assessment that Opella

qualifies as a principal line of business within the meaning of IFRS 5, the net income or loss of Opella is presented in a separate line

item, Net income from discontinued operations (see Notes D.1. and D.36. to our consolidated financial statements included at

Item 18. of this annual report).

In 2025, Net income from discontinued operations amounted to € 2,874 million, reflecting the net income of Opella until the

date of loss of control and also including a net gain of €2.6 billion resulting from the divestment of Opella as of the date of loss of

control.

In 2024, Net income from discontinued operations amounted to € 64 m illion.

18/ Net income attributable to non-controlling interests

Net income attributable to non-controlling interests was € 38 million in 2025 , versus € 58 million in 2024 .

19/ Net income attributable to equity holders of Sanofi

Net income attributable to equity holders of Sanofi amounted to € 7,813 million in 2025 , compared with € 5,560 million in 2024 .

Basic earnings per share for 2025 was € 6.40 versus € 4.44 for 2024 , based on an average number of shares outstanding

o f 1,220.4 million in 2025 and 1,251.4 million in 2024 . Diluted earnings per share for 2025 was € 6.37 versus € 4.43 for 2024 , based

on an average number of shares after dilution of 1,225.6 million in 2025 and 1,256.1 million in 2024 .

A.2.3. Segment results

For the Biopharma segment, business operating income (as defined in Note D.35. to our consolidated financial statements

included at Item 18. of this annual report) was € 12,123 million in 2025 , compared with € 11,285 million in 2024 (an increase of 7.4% ).

It represented 27.8% of our net sales in 2025 , compared with 27.5% in 2024 .

B. Liquidity and capital resources

Our operations generate significant positive cash flows. We fund our day-to-day investments (with the exception of significant

acquisitions) primarily with operating cash flow, and pay regular dividends on our shares.

“Net debt” is a non-IFRS financial indicator which is reviewed by our management, and which we believe provides useful

information to measure our overall liquidity and capital resources. We define “net debt” as (i) the sum total of long-term debt,

short-term debt and current portion of long-term debt, and interest rate and currency derivatives used to manage debt, minus

(ii) the sum total of cash and cash equivalents and interest rate and currency derivatives used to manage cash and cash

equivalents. Lease liabilities are not included in net debt.

As of December 31, 2025 our total debt was €18,702 million and our net debt was € 11,008 million, compared with €16,137 million

and € 8,772 million, respectively, as of December 31, 2024 . See reconciliation of total debt to net debt in "— B.2. Consolidated

balance sheet and debt" below.

In order to assess our financing risk, we also use the “gearing ratio," a non-IFRS financial measure (see table in section

“— B.2. Consolidated balance sheet and debt” below). We define the gearing ratio as the ratio of net debt to total equity. As

of December 31, 2025 , our gearing ratio was 15.4 %, compared with 11.3 % as of December 31, 2024 .

Because our net debt and gearing ratio are not standardized measures, they may not be directly comparable with the non-IFRS

financial measures of other companies using the same or similar non-IFRS financial measures. Despite the use of non-IFRS

SANOFI FORM 20-F 2025 77

PART I
ITEM 5. Operating and Financial Review and Prospects

measures by management in setting goals and measuring performance, these are non-IFRS measures that have no standardized

meaning prescribed by IFRS.

B.1. Consolidated statement of cash flows

Generally, factors that affect our earnings – for example, pricing, volume, costs and exchange rates – flow through to cash from

operations. The most significant source of cash from operations is sales of our branded medicines and vaccines. Receipts of

royalty payments also contribute to cash from operations.

Net cash provided by/used in continuing operating activities represented a net cash inflow of € 10,561 million in 2025 ,

compared with € 8,607 million in 2024 . The year-on-year increase was due mainly to a lower level of operating cash flow before

changes in working capital (€ 8,766 million in 2025 , versus € 9,222 million in 2024 ), more than offset by a net increase of

€ 1,795 million in the working capital requirement in 2025 (versus a net decrease of € 615 million in 2024 ), including the change in

the US rebate provisions (€1,330 million) following the decision to reduce the Lantus list price effective January 1, 2024.

Net cash provided by/used in continuing investing activities represented a net cash outflow of € 12,849 million in 2025 ,

compared with a net outflow of € 4,298 million in 2024 . The principal cash outflow in 2025 was the €9,394 million arising from

Acquisitions of consolidated undertakings and investments accounted for using the equity method , in particular Blueprint

Medicines (€ 7,542 million) and Vicebio (€ 968 million); that compares with an outflow of €1,901 million in 2024 (mainly related to

the acquisition of Inhibrx for $2,035 million ).

Acquisitions of property, plant and equipment and intangible assets amounted to € 3,538 million, versus € 3,195 million in 2024 .

There were € 1,762 million of acquisitions of property, plant and equipment (versus € 1,733 million in 2024 ), most of which related

to industrial facilities. Acquisitions of intangible assets (€ 1,776 million, versus € 1,462 million in 2024 ) mainly comprised contractual

payments for intangible rights under license and collaboration agreements.

Proceeds from disposals of property, plant and equipment, intangible assets and other non-current assets, net of tax

amounted to € 847 million in 2025 versus € 1,461 million in 2024 ; the 2024 figure mainly comprised the sale of the Enjaymo global

rights to Recordati for pre-tax proceeds of €768 million .

Net ca sh provided by/used in continuing financing activities represented a net cash outflow of € 8,159 million in 2025 ,

compared with a net cash outflow of € 5,751 million in 2024 . The 2025 figure includes the redemption of €2.6 billion of bonds, and

the issuance of new bonds for €1.5 billion, €1.5 billion and $3.0 billion respectively. Other movements mainly included (i) the

dividend payout to our shareholders of € 4,772 million (versus € 4,704 million in 2024 ); and (ii) a cash outflow of €5,030 million on

purchases of treasury shares (versus €302 million in 2024).

The net change in cash and cash equivalents of continuing operations in 2025 was a decrease of € 9 million, versus a

decrease of € 1,442 million in 2024 .

Net cash flows of the discontinued Opella business represented a net cash inflow of € 105 million in 2025 versus a net cash

inflow of € 353 million in 2024 .

Net cash inflow from the Opella transaction represented a net cash inflow of € 10,438 million in 2025 . This amount includes

€ (667) million in respect of cash and cash equivalents held by Opella as of April 30, 2025. As of December 31, 2024, cash and

cash equivalents held by Opella amounted to €167 million, and were reported in Assets held for sale in the balance sheet as of

that date.

PART I
ITEM 5. Operating and Financial Review and Prospects

The net change in cash and cash equivalents during 2025 was an increase of € 216 million; this compares with a decrease of

€ 1,269 million in 2024 .

“Free cash flow” (a non-IFRS measure) for the year ended December 31, 2025 was € 8,089 million, an increase from the 2024

figure of € 5,955 million.

For details of the arrangements in place to manage our liquidity needs for current operations as of December 31, 2025 , refer to

Note 17.1.(b) to our consolidated financial statements, included at Item 18. of this annual report.

“Free cash flow” is a non-IFRS financial indicator which is reviewed by our management, and which we believe provides useful

information to measure the net cash generated from our operations that is available for strategic investments (1) (net of

divestments (1) ), for debt repayment, and for payments to shareholders. “Free cash flow” comprises cash flows generated from our

continuing operations; it is calculated from our “Business net income” (2) after adding back (in the case of expenses and losses) or

deducting (in the case of income and gains) the following items: depreciation, amortization and impairment, share of undistributed

earnings from investments accounted for using the equity method, gains & losses on disposals, net change in provisions including

pensions and other post-employment benefits, deferred taxes, share-based payment expense and other non-cash items. It also

includes net changes in working capital, capital expenditures and other asset acquisitions (3) net of disposal proceeds (3) , and

payments related to restructuring and similar items. “Free cash flow” is not defined by IFRS, and is not a substitute for Net cash

provided by operating activities as reported under IFRS. Management recognizes that the term “Free cash flow” may be

interpreted differently by other companies and under different circumstances.

The table below sets forth a reconciliation between Net cash provided by continuing operating activities and “Free cash flow”:

(€ million)	2025	2024
Net cash provided by/(used in) operating activities (IFRS)	10,750	9,081
Net cash provided by/(used in) operating activities (IFRS) of the discontinued Opella business	(189)	(474)

Acquisitions of intangible assets, equity interests and other non-current financial assets (a)	(1,761)	(1,434)
Proceeds from disposals of property, plant and equipment, intangible assets and other non-current assets, net of tax (a)	744	805
Repayments of lease liabilities (b)	(333)	(282)
Other items (c)	736	67
Free cash flow (non-IFRS)	8,089	5,955

(a) Free cash flow includes investments and divestments not exceeding a cap of €500 million per transaction.

(b) Cash outflows relating to repayments of the principal portion of lease liabilities (IFRS 16) are included in free cash flow.

(c) This line item includes cash outflows from major litigation not included in "Free cash flow," in particular the Plavix litigation in Hawaii in 2025.

B.2. Consolidated balance sheet and debt

Total assets were € 126,805 million as of December 31, 2025 , compared with € 132,798 million as of December 31, 2024 , a decrease

of € 5,993 million.

Total equity was € 71,710 million as of December 31, 2025 , versus € 77,857 million as of December 31, 2024 . The year-on-year net

change reflects the following principal factors:

• increases: our net income for 2025 (€ 7,851 million); and

• decreases: the dividend paid to our shareholders in respect of the 2024 financial year (€ 4,772 million), repurchases of our own

shares (€ 5,015 million) and negative currency translation differences (€ 4,867 million).

“ Total debt” was €18,702 million as of December 31, 2025 , compared with €16,137 million as of December 31, 2024 . "Net debt" was

€ 11,008 million as of December 31, 2025 , compared with € 8,772 million as of December 31, 2024 . The increase in 2025 mainly

reflects cash outflows related to (i) acquisitions exceeding a cap of €500 million per transaction (cash outflow of €10,986 million)

and (ii) the dividend payout to our shareholders (cash outflow of € 4,772 million), less the € 8,089 million of free cash flow

generated from continuing operations in the year (see reconciliation with Net cash provided by/(used in)operating activities in

section B.1. above) and the €10,443 million cash inflow from the Opella transaction.

“Net debt” is a non-IFRS financial measure which is reviewed by our management, and which we believe provides useful

information to measure our overall liquidity and capital resources. We define “net debt” as (i) the sum total of long-term debt,

short-term debt and current portion of long-term debt and interest rate and currency derivatives used to manage debt, minus

(ii) the sum total of cash and cash equivalents and interest rate and currency derivatives used to manage cash and cash

equivalents.

(a) Net debt does not include lease liabilities, which amounted to € 1,739 million as of December 31, 2025 and € 1,906 million as of December 31, 2024 .

“Net debt” is a non-IFRS financial measure used by management and investors to measure Sanofi’s overall net indebtedness.

To assess our financing risk, we use the “gearing ratio”, a non-IFRS financial measure. This ratio (which we define as the ratio of

net debt to total equity) increased from 11.3 % as of December 31, 2024 to 15.4 % as of December 31, 2025 . Analyses of debt as

of December 31, 2025 and December 31, 2024 by type, maturity, interest rate and currency, are provided in Note D.17.1. to our

consolidated financial statements, included at Item 18. of this annual report.

We expect that the future cash flows generated by our operating activities will be sufficient to repay our debt. The financing

arrangements in place as of December 31, 2025 at the Sanofi parent company level are not subject to covenants regarding

financial ratios and do not contain any clauses linking fees to Sanofi’s credit rating.

As of December 31, 2025 , we held 11.96 million of our own shares, recorded as a deduction from equity and representing 0.98 % of

our share capital. As of December 31, 2024 , we were holding 9.5 million of our own shares, recorded as a deduction from equity

and representing 0.75% of our share capital.

Goodwill and Other intangible assets (€ 67,561 million in total) increased by € 1,548 million , driven mainly by new acquisitions

(DR-0201, Blueprint, Vigil and Vicebio), partly offset by amortization and impairment charged during the period and movements

in currency translation differences.

Investments accounted for using the equity method (€ 3,259 million) increased by € 2,943 million, mainly reflecting the

acquisition of 48.2% in the associate OPAL JV Co.

Other non-current assets amounted to € 4,364 million, a year-on-year increase of € 611 million.

Net deferred tax assets amounted to € 6,942 million as of December 31, 2025 , versus € 5,801 million as of December 31, 2024 , a

year-on-year increase of € 1,141 million. The year-on-year increase mainly reflects (i) an increase in tax losses available for carry-

forward; and (ii) an increase in deferred tax assets arising on the spread tax deduction of R&D expenses in the US.

Non-current provisions and other non-current liabilities (€ 6,703 million) showed a decrease of € 1,393 million, mainly due to

funding of pension obligations and various litigation settlements.

Liabilities related to business combinations and to non-controlling interests were € 56 million lower year-on-year, at

€ 585 million.

Assets held for sale (€ 208 million) and Liabilities related to assets held for sale (€ 54 million) were both substantially lower than

in 2024, when these line items included the assets and liabilities of the held-for-sale Opella business, over which Sanofi lost

control in 2025 (see Note D.8. to our consolidated financial statements included at Item 18. of this annual report).

B.3. Liquidity

We expect that our existing cash resources and cash from operations will be sufficient to finance our foreseeable working capital

requirements, in both the short term (i.e. the 12 months following the year ended December 31, 2025 ) and the long term

(i.e. beyond such additional 12-month period). As of December 31, 2025 , we held cash and cash equivalents amounting to

€ 7,657 million (see Note D.13. to our consolidated financial statements included at Item 18. of this annual report). As of December

31, 2025 , €490 million of our cash and cash equivalents were held by captive insurance and reinsurance companies in

accordance with insurance regulations.

We run the risk of delayed payments or even non-payment by our customers, who consist principally of wholesalers, distributors,

pharmacies, hospitals, clinics and government agencies (see “Item 3. Key information — D. Risk Factors — 2. Risks Relating to Our

Business — We are subject to the risk of non-payment by our customers”). Deteriorating credit and economic conditions and other

factors in some countries have resulted in, and may continue to result in, an increase in the average length of time taken to collect our

accounts receivable in these countries. Should these factors continue, it may require us to re-evaluate the collectability of these

receivables in future periods. We carefully monitor sovereign debt issues and economic conditions and evaluate accounts receivable in

these countries for potential collection risks. We have been conducting an active recovery policy, adapted to each country and including

intense communication with customers, negotiations of payment plans, charging of interest for late payments, and legal action. Over our

business as a whole, the amount of trade receivables overdue by more than 12 months (which primarily consists of amounts due from

public sector bodies) increased from € 44 million as of December 31, 2024 to € 52 million as of December 31, 2025 (see Note D.10. to our

consolidated financial statements included at Item 18. of this annual report).

ITEM 5. Operating and Financial Review and Prospects

As of December 31, 2025 , we had no commitments for capital expenditures that we consider to be material to our consolidated

financial position. Undrawn confirmed credit facilities amounted to a total of € 8,000 million at December 31, 2025 . For a

discussion of our treasury policies, see “Item 11. Quantitative and Qualitative Disclosures about Market Risk.”

We expect that cash from our operations will be sufficient to repay our debt. For a discussion of our liquidity risks,

see “Item 11. Quantitative and Qualitative Disclosures about Market Risk.”

B.4. Off balance sheet arrangements/Contractual obligations and other commercial commitments

We have various contractual obligations and other commercial commitments arising from our operations. Our contractual

obligations and our other commercial commitments as of December 31, 2025 are shown in Notes D.3., D.17., D.18., and D.21. to our

consolidated financial statements included at Item 18. of this annual report. Note D.21. to our consolidated financial statements

included at Item 18. of this annual report discloses details of commitments under our principal research and development

collaboration agreements. For a description of the principal contingencies arising from certain business divestitures, refer to

Note D.22. to our 2025 consolidated financial statements included at Item 18. of this annual report.

Off balance sheet commitments relating to Sanofi’s operating activities, not including as of December 31, 2025 the commitments

of the held-for-sale Opella operation, comprise the following (for Opella off balance sheet commitments, refer to Note D.36.):

financial statements included at Item 18. of this annual report) and (ii) goods and services.

(e) This line includes all milestone payments on projects regarded as reasonably possible, i.e. on projects in the development phase.

(f) See Note D.18. to our consolidated financial statements included at Item 18. of this annual report.

(g) See Note D.19.1. to our consolidated financial statements included at Item 18. of this annual report. The table above does not include ongoing annual

employer’s contributions to plan assets, estimated at € 29 million for 2025 .

We may have payments due to our current or former research and development partners under collaboration agreements.

These agreements typically cover multiple products, and give us the option to participate in development on a product-by-

product basis. When we exercise our option with respect to a product, we pay our collaboration partner a fee and receive

intellectual property rights to the product in exchange. We are also generally required to fund some or all of the development

costs for the products that we select, and to make payments to our partners when those products reach development

milestones.

We have entered into collaboration agreements under which we have rights to acquire products or technology from third parties

through the acquisition of shares, loans, license agreements, joint development, co-marketing and other contractual

arrangements. In addition to upfront payments on signature of the agreement, our contracts frequently require us to make

payments contingent upon the completion of development milestones by our alliance partner or upon the granting of approvals

or licenses.

Because of the uncertain nature of development work, it is impossible to predict (i) whether Sanofi will exercise further options for

products, or (ii) whether the expected milestones will be achieved, or (iii) the number of compounds that will reach the relevant

milestones. It is therefore impossible to estimate the maximum aggregate amount that Sanofi will actually pay in the future under

existing collaboration agreements.

Given the nature of its business, it is highly unlikely that Sanofi will exercise all options for all products or that all milestones will be

achieved.

ITEM 5. Operating and Financial Review and Prospects

The main collaboration agreements relating to development projects are described in Note D.21.1. to our consolidated financial

statements included at Item 18. of this annual report. Milestone payments relating to development projects under these

agreements included in the table above exclude projects still in the research phase (€ 13.9 billion in 2025 , € 14.4 billion in 2024 )

and payments contingent upon the attainment of sales targets once a product is on the market (€ 15.6 billion in 2025 , € 15.2 billion

in 2024 ).

C. Research and development, patents and licenses, etc.

Our research and development teams utilize our deep expertise to contribute to the growth of our business. As of December 31,

2025 , we had 9,274 employees engaged in research and development activities. In the years ended December 31, 2024 and 2025

we spent € 7,394 million and € 7,842 million, respectively, on research and development. For a discussion of our research and

development activities, see “Item 4. Information on the Company — B. Business Overview” and section “— A. Operating Results”

ITEM 6. Directors, Senior Management and Employees

Item 6. Directors, Senior Management and Employees

A. Directors and Senior Management

Since January 1, 2007, Sanofi has separated the offices of Chairman and Chief Executive Officer. Annual evaluations conducted

since that date have indicated that this governance structure is appropriate to Sanofi’s current configuration. When the term of

office of Serge Weinberg as Chairman ended and Frédéric Oudéa was appointed in May 2023, our Board of Directors decided to

continue separating the offices of Chairman and Chief Executive Officer. The Board believes this governance structure is still

appropriate to the current context in which Sanofi operates and its share ownership structure, as well as protecting the rights of

all of its stakeholders.

The Chairman organizes and directs the work of the Board, and is responsible for ensuring the proper functioning of the

corporate decision-making bodies in compliance with good governance principles. The Chairman coordinates the work of the

Board of Directors with that of its Committees. He ensures that the Company’s management bodies function properly, and in

particular that the directors are able to fulfill their duties. The Chairman is accountable to the Shareholders’ General Meeting,

which he chairs.

In addition to these roles conferred by law, the Chairman:

• in coordination with the Chief Executive Officer, liaises between the Board of Directors and the shareholders of the Company;

• is kept regularly informed by the Chief Executive Officer of significant events and situations affecting the affairs of the

Company, and may request from the Chief Executive Officer any information useful to the Board of Directors;

• may, in close collaboration with the Chief Executive Officer, represent the Company in high-level dealings with governmental

bodies and with key partners of the Company and/or of its subsidiaries, both nationally and internationally;

• seeks to prevent any conflict of interest and manages any situation that might give rise to a conflict of interest. He also gives

rulings, in the name of the Board, on requests to take up external directorships of which he may become aware or that may be

submitted to him by a director;

• may interview the statutory auditors in preparation for the work of the Board of Directors and the Audit Committee; and

• strives to promote in all circumstances the values and image of the Company.

The Chairman is also required to develop and maintain a proper relationship of trust between the Board and the Chief Executive

Officer, so as to ensure that the latter consistently and continuously implements the orientations determined by the Board.

In fulfilling his remit, the Chairman may meet with any individual, including senior executives of the Company, while avoiding any

involvement in directing the Company or managing its operations, which are exclusively the responsibility of the Chief Executive

Officer.

Finally, the Chairman reports to the Board on the fulfillment of his remit.

The Chairman carries out his duties during the entire period of his term of office, subject to the caveat that a director who is a

natural person may not be appointed or reappointed once that director has reached the age of 70.

The Chief Executive Officer manages the Company, and represents it in dealings with third parties within the limit of the

corporate purpose. The Chief Executive Officer has the broadest powers to act in all circumstances in the name of the Company,

subject to the powers that are attributed by law to the Board of Directors and to the Shareholders’ General Meeting and within

the limits set by the Board of Directors.

The Chief Executive Officer must be less than 65 years old. A proposed amendment to the Articles of Association will be

submitted to a shareholder vote at the Annual General Meeting of April 29, 2026, intended to raise the age limit applicable to a

Chief Executive Officer on the date of their appointment.

Limitations on the powers of the Chief Executive Officer set by the Board

The limitations on the powers of the Chief Executive Officer are specified in the Board Charter. Without prejudice to legal

provisions regarding authorizations that must be granted by the Board (regulated agreements, guarantees, divestments of equity

holdings or real estate, etc.), prior approval from the Board of Directors is required for transactions or decisions resulting in an

investment or divestment, or an expenditure or guarantee commitment, made by the Company and its subsidiaries, in excess of:

• a cap of €500 million (per transaction) for transactions, decisions or commitments pertaining to a previously approved

strategy; and

• a cap of €150 million (per transaction) for transactions, decisions or commitments not pertaining to a previously approved

strategy.

When such transactions, decisions or commitments give rise to installment payments to the contracting third party (or parties)

that are contingent upon future results or objectives, such as the registration of one or more products, attainment of the caps is

calculated by aggregating the various payments due from the signing of the contract up to and including the filing of the first

application for marketing authorization in the US or in Europe.

SANOFI FORM 20-F 2025 83

PART I
ITEM 6. Directors, Senior Management and Employees

Attainment of the above caps is also assessed after taking into account all commitments to make payments upon exercising a

firm or conditional option with immediate or deferred effect, and all guarantees or collateral to be provided to third parties over

the duration of such commitments.

The prior approval procedure does not apply to transactions and decisions that result in the signature of agreements that solely

involve subsidiaries and the Company itself.

Remit of the Board of Directors

The Board of Directors establishes the orientation of the Company’s activities and ensures that they are implemented, paying

due consideration to social and environmental issues. Subject to those powers expressly attributed to Shareholders’ General

Meetings and within the limits set by the corporate purpose, the Board addresses any issue of relevance to the proper conduct of

the Company’s affairs and, through its deliberations, settles matters concerning the Company.

French law, Articles of Association and Board Charter

The rules and operating procedures of our Board of Directors are defined by French law, by our Articles of Association, and by our

Board Charter (English language versions of which are reproduced in full as Exhibit 1.1 and Exhibit 1.2 to this annual report).

Our Board Charter describes the rights and obligations of Board members; the composition, role and operating procedures of the

Board of Directors and Board Committees; and the roles and powers of the Chairman and the Chief Executive Officer. It is

prepared in accordance with the French Commercial Code and our Articles of Association.

Composition of the Board of Directors

As of February 17, 2026, the Sanofi Board of Directors has 16 members, including 11 independent directors and two directors

representing employees.

43% of our Board members (excluding the two directors representing employees) are women. In accordance with Order no.

2024-934 of October 15, 2024 and the associated enabling decree no. 2025-744 of July 30, 2025 (which transposed into French

law Directive (EU) 2022/2381 of the European Parliament and of the Council of November 23, 2022), the rules relating to gender

balance on the Boards of listed companies apply solely to the cohort of directors comprising (i) ordinary directors and (ii)

directors representing employee shareholders (none of whom sit on our Board of Directors). Specific gender balance rules apply

to the cohort of directors representing employees but only where there are at least three such directors, which is not the case at

Sanofi.

50% of our Board members (including directors representing employees) were non-French nationals.

SANOFI FORM 20-F 2025 85

PART I
ITEM 6. Directors, Senior Management and Employees

In line with current legislation and given that less than 3% of our share capital is owned by our employees, Sanofi does not have a

director representing its employee shareholders.

Term of Office

The term of office of directors is four years. Directors are required to seek reappointment by rotation, such that members of the

Board are required to seek reappointment on a regular basis in the most equal proportions possible. Exceptionally, the

Shareholders’ Ordinary General Meeting may appoint a director to serve for a term of one, two or three years, in order to ensure

an adequate rotation of Board members. Each director standing down is eligible for reappointment. Should one or more

directorships fall vacant as a result of death or resignation, the Board of Directors may make provisional appointments in the

period between two Shareholders’ General Meetings, in accordance with applicable laws.

Directors may be removed from office at any time by a Shareholders’ General Meeting.

A natural person cannot be appointed or reappointed as a director once he or she reaches the age of 70. As soon as the number

of directors over the age of 70 represents more than one-third of the directors in office, the oldest director shall be deemed to

have resigned; his or her term of office shall end at the date of the next Shareholders’ Ordinary General Meeting.

PART I
ITEM 6. Directors, Senior Management and Employees

The terms of office of Paul Hudson, Christophe Babule, Jean-Paul Kress and Patrick Kron will expire at the close of the Annual

General Meeting to be held on April 29, 2026 . The Appointments, Governance and CSR Committee meeting recommended the

renewal of the terms of office of Christophe Babule and Jean-Paul Kress. Draft resolutions to be submitted for shareholder

approval at the Annual General Meeting on April 29, 2026 will be approved by the Board of Directors in March 2026, and will be

communicated in the Notice of Meeting. As things stand, however it is not proposed to renew Paul Hudson' term of office (see

"Item 8. Financial Information — Other Changes") nor Patrick Kron's term of office, given that he would by then have served as a

director of Sanofi for 12 years and hence would no longer be considered as independent under the AFEP-MEDEF Code, and the

Annual General Meeting will be asked to:

• renew the terms of office of:

– Christophe Babule – refer to “— Detailed Information about Members of the Board of Directors” for his biographical details,

and to “— Competencies of Board Members” below for details of what he brings to the Board; and

– Jean-Paul Kress – refer to “— Detailed Information about Members of the Board of Directors” for her biographical details,

and to “— Competencies of Board Members” below for details of what he brings to the Board;

• appoint two new directors, who would bring the following competencies to the Board:

– Belén Garijo: scientific training, healthcare/pharmaceutical industry experience, senior executive role in international

groups, directorship in international groups, international experience, mergers & acquisitions, sustainable development,

digitalization/AI implementation,

– Christel Heydemann: senior executive role in international groups, directorship in international groups, international

experience, mergers & acquisitions, sustainable development, digitalization/AI implementation.

Rules relating to the composition of the Board and its Committees

Each year, the Board of Directors conducts a review to ensure that there is an appropriate balance in its composition and in the

composition of its Committees. In particular, the Board seeks gender balance and a broad range of competencies, experiences,

nationalities and ages, reflecting our status as a diversified global business. The Board investigates and evaluates not only

potential candidates, but also whether existing directors should seek reappointment. Above all, the Board seeks directors who

show independence of mind and are competent, dedicated and committed, with compatible and complementary personalities.

Acting on proposals from the Chief Executive Officer and in liaison with the Appointments, Governance and CSR Committee, the

Board seeks to implement the AFEP-MEDEF recommendation and forthcoming applicable French rules on gender representation

in Sanofi’s executive bodies, and more generally by bringing a breadth of diverse experiences, backgrounds and expertise to

Sanofi's executive bodies, and across the Company. That commitment to non-discrimination, fairness and inclusion is included in

our Play to Win strategy. As of December 31, 2025 , 25% of our 12 Executive Committee members were women, and 58% were

non-French nationals.

The Board of Directors is also kept informed, in particular during its annual discussion on its equal opportunity and equal pay

policy, on how Sanofi’s inclusion and representation policy is cascaded down to “Senior Leaders” and “Executives” (the positions

in Sanofi with the highest level of responsibility).

Competencies of Board members

The Board of Directors, in liaison with the Appointments, Governance and CSR Committee, must ensure that the composition of

the Board is balanced, diverse and fit for purpose.

In assessing its composition, the Board takes account of the new challenges facing Sanofi and our corporate strategy, and

determines whether the qualities and skills of serving directors are sufficient for the Board to deliver on its remit.

In parallel, as part of its work the Appointments, Governance and CSR Committee keeps track of competencies among Board

members. In December 2025, the Committee conducted a detailed review of the matrix of competencies; competencies

reported by each director were evaluated by the Committee, and the final matrix was signed off by the Board of Directors. This

shows that in recent years, the Board has adapted its composition by bringing in additional scientific expertise and maintaining

the level of other key competencies, especially in finance and accounting.

Director Training

In 2025 , Board members received four training modules delivered by in-house and/or external specialists, dealing with the

following key issues:

• Key principles of immunology: brief history of immunology, nature and function of the immune system, plus case studies and

real-life examples of how Sanofi medicines and vaccines are used.

• European Union regulatory framework: overview of EU institutions, description of European Commission priorities, review of

key European texts governing the pharmaceutical industry (pricing/terms of reimbursement, evaluation of healthcare

technologies, clinical trials), and an analysis of Sanofi's position in relation to European regulations and institutions.

• Equitable access to healthcare: summary of key issues around equitable access to healthcare, description of access barriers in

low-to-middle income countries or in low-income populations, outline of levers for pharmaceutical companies to improve

access.

• Artificial Intelligence (AI) in the biopharma sector: history and development of the various types of AI (generative, agentic and

physical), and current trends; overview of general-use cases for agentic AI, potential for rollout in biopharma (R&D, operations,

information technology, support functions, etc.); comparison with industry peers.

The training plan for 2026 was agreed upon by the Board of Directors on February 11, 2026 , and will include modules on the

alliance with Regeneron; the impacts of GLP-1 drugs; healthcare insurance around the world (public and private); and in CSR,

climate and nature related risks and opportunities, resilience, and the impacts on Sanofi.

Independence of Board Members

Under the terms of the AFEP-MEDEF Code, a director is independent when he or she has no relationship of any kind whatsoever

with the Company, its group or its senior management that may color his or her judgment. More specifically, a director can only

be regarded as independent if he or she:

• is not (and has not been during the past five years):

– an employee or executive officer of the Company,

– an employee, executive officer or director of an entity consolidated by the Company, or

– an employee, executive officer or director of the Company’s parent, or of an entity consolidated by that parent (criterion 1);

88 SANOFI FORM 20-F 2025

PART I
ITEM 6. Directors, Senior Management and Employees

• is not an executive officer of an entity in which (i) the Company directly or indirectly holds a directorship or (ii) an employee of

the Company is designated as a director or (iii) an executive officer of the Company (currently, or within the past five years)

holds a directorship (criterion 2);

• is not a customer, supplier, investment banker or corporate banker that is material to the Company or its group, or for whom

the Company or its group represents a significant proportion of its business (criterion 3);

• has no close family ties with a corporate officer of the Company (criterion 4);

• has not acted as an auditor for the Company over the course of the past five years (criterion 5);

• has not been a director of the Company for more than 12 years (criterion 6);

• does not receive variable compensation in cash or in the form of shares or any compensation linked to the performance of the

Company or its group (criterion 7); or

• does not represent a shareholder that has a significant or controlling interest in the Company (criterion 8).

The influence of other factors such as the ability to understand challenges and risks, and the courage to express ideas and form a

judgment, is also evaluated before it is decided whether a director can be regarded as independent.

In accordance with our Board Charter and pursuant to the AFEP-MEDEF Code, the Board of Directors’ meeting of February 11,

2026 discussed the independence of the current directors. Of the 16 directors in office on that date, 11 were deemed to be

independent directors by reference to the independence criteria used by the Board of Directors pursuant to the AFEP-MEDEF

Code: Frédéric Oudéa, Clotilde Delbos, Rachel Duan, Carole Ferrand, Lise Kingo, Jean-Paul Kress, Patrick Kron, Anne-Françoise

Nesmes, John Sundy, Emile Voest and Antoine Yver.

In accordance with the rules described above, Paul Hudson (who is an executive officer of Sanofi until end-of-day on February 17,

2026), and Barbara Lavernos and Christophe Babule (who were appointed on the recommendation of L’Oréal, a major

shareholder of Sanofi), are not deemed independent.

Consequently, as of February 17, 2026 the proportion of independent directors is 79% . This complies with the AFEP-MEDEF

recommendation of at least 50% in companies with dispersed ownership and no controlling shareholder (which is the case for

Sanofi). In accordance with the recommendations of the AFEP-MEDEF Code, directors representing employees are excluded

when calculating the proportion of independent directors.

l Independence criterion met X Independence criterion not met

(a) This table only refers to independence as defined under the AFEP-MEDEF Code. However, Christophe Babule is independent for the purposes of the

NASDAQ Listing Rules and Rule 10A-3 under the Exchange Act.

Failure to fulfil one of the criteria does not automatically disqualify a director from being independent.

In assessing the criterion related to significant business relationships (criterion 3), the Board of Directors took into account the

various relationships between directors and Sanofi and concluded that there was no relationship of a kind that might undermine

their independence. The Board of Directors noted that the Company and its subsidiaries had, in the normal course of business,

over the past three years, sold products and provided services to, and/or purchased products and received services from,

companies in which certain of the Company's directors, who are classified as independent (or their close family members) were

SANOFI FORM 20-F 2025 89

PART I
ITEM 6. Directors, Senior Management and Employees

senior executives or employees during 2025 . In each case, the amounts paid to or received from such companies in the recent

years were determined on an arm's length basis and not at amounts that the Board regarded as undermining the independence

of the directors in question.

Selection process for Board members

The Appointments, Governance and CSR Committee has a remit to organize a procedure for selecting future directors. Once the

desired profile and skillset for a new director has been defined, a search for potential candidates is conducted by external

consultants.

Once a shortlist has been established, the Committee interviews two or three candidates. The candidates also meet with the

Chairs of the other Board committees, and in some cases the other Committee members as well. In all cases, they meet with the

Chairman of the Board of Directors and the Chief Executive Officer. After completing the interviews, the Committee makes a

recommendation to the Board on the candidate with the best fit for the profile, supporting that recommendation with an

explanation of how the interviews were conducted and giving reasons why a candidate was selected. Before recommending a

candidate to the Board, the Committee obtains assurance as to their availability, in particular as regards any other executive

posts or offices the candidate may hold.

Succession planning

General principles

The remit of the Appointments, Governance and CSR Committee includes preparing for the future of the Company’s executive

bodies, in particular through the establishment of a succession plan for each of the executive officers , i.e., separate succession

plans for the Chief Executive Officer and the Chairman of the Board.

Those plans are reviewed at meetings of the Appointments, Governance and CSR Committee, and address various scenarios:

• unplanned vacancy due to prohibition, resignation or death;

• forced vacancy due to poor performance, mismanagement or misconduct; and

• planned vacancy due to retirement or expiration of term of office.

Through its work and discussions, the Committee seeks to devise succession plans that are adaptable to situations arising in the

short, medium or long term, but which also build in diversity – in all its facets – as a key factor.

To fulfill its remit, the Appointments, Governance and CSR Committee:

• provides the Board with progress reports, in particular at executive sessions;

• co-ordinates with the Compensation Committee. A director sitting both committees is beneficial for coordination purposes;

• works closely with the Chief Executive Officer to (i) ensure succession plans are consistent with the Company’s own practices

and market practices, (ii) ensure high-potential internal prospects receive appropriate support and training, and (iii) check

there is adequate monitoring of key posts likely to fall vacant;

• meets key executives on an ad hoc basis; and

• involves the Chairman and the Chief Executive Officer insofar as each has a key role in planning for his own successor, though

without them directing the process.

90 SANOFI FORM 20-F 2025

PART I
ITEM 6. Directors, Senior Management and Employees

In fulfilling their remit, Committee members are acutely conscious of confidentiality issues.

Although the Committee is aware that separating the offices of Chairman and Chief Executive Officer provides continuity of

power, it nonetheless assesses the situation of the Chairman of the Board as well as that of the executive team. Emergency

succession planning for the Chairman of the Board, and solutions for a smooth transition to the appointment of a new Chairman

should the need arise, were reviewed by the Appointments, Governance and CSR Committee at its meeting of February 4, 2026.

Succession planning for the Chief Executive Officer

Succession planning for the post of Chief Executive Officer relied on work initiated in mid-2024 with a systematic analysis of

potential candidates, both internal and external. The Appointments, Governance and CSR Committee reviewed the findings of

that analysis, and identified potential candidates in a very short time horizon, alongside others considered to be potentially ready

for the role in a three-to-five-year time horizon. In addition, a number of young high-potential individuals were identified for a

five-to-ten-year time horizon.

That process was updated towards the end of 2025. From October 2025, the Appointments, Governance and CSR Committee

produced a recommendation on the required profile for potential successors, which was approved by the Board. The Committee

also updated the list of potential internal candidates, and retained a new external consultant to take a second look at the list of

potential external candidates. Based on the needs identified by the Committee (and adopted by the Board), in terms of both their

expertise and their leadership profile, the Committee finalized a shortlist of candidates and held individual interviews with each of

them.

The Committee met in January 2026 and unanimously recommended that the Board meet with Belén Garijo, whose profile

offered the best fit with the expectations expressed. The Board first spoke with Paul Hudson, at its meeting on January 28, 2026,

about his ambitions to potentially renew his term of office, and then interviewed Belén Garijo in executive session on

February 7, 2026. At its meeting of February 10, 2026, the Committee discussed the matter and prepared a recommendation to

the Board that Belén Garijo be appointed as Chief Executive Officer to succeed Paul Hudson. That recommendation was based

mainly on her profile in an international executive role with a listed company; her acknowledged expertise and strategic vision in

the pharmaceutical industry; her broad range of experience, in particular her many years in research and development; the

success she had achieved in the 15 years of her career spent at Sanofi; her capacity to step up the pace and quality of execution

of Sanofi's strategy, and hence steer the business through its next growth cycle; and finally, her ability to bring rigour and

discipline to the management of deep, value-creating transformations.

Evaluation of the Board and its Committees

Under the terms of the Board Charter, and in accordance with the AFEP-MEDEF Code, a discussion of the operating procedures

of the Board and its committees must be included on the agenda of one Board meeting every year. The Charter also requires a

formal evaluation to be performed at least every three years under the direction of the Appointments, Governance and CSR

Committee, with assistance from an independent external consultant.

Since 2023 the evaluation procedure has included one-on-one interviews with each director (including the Chief Executive

Officer), intended to measure the contribution of each director to the work of the Board and its committees and to record any

suggestions they may have.

In practice, even in years when the three-yearly formal evaluation procedure (assisted by an independent external consultant) is

not conducted, the Board conducts an annual internal evaluation using a detailed questionnaire sent to directors by the

Secretary to the Board, and covering the composition and the operation of the Board and its committees. The responses (which

are confidential) are analyzed by the Secretary to the Board. A summary is then presented and discussed at a meeting of the

Appointments, Governance and CSR Committee; a detailed report finalized at that meeting is submitted to a Board meeting for

discussion at the start of the following year.

The last formal evaluation supported by a specialist consultancy firm was conducted under the direction of the Appointments,

Governance and CSR Committee in 2024.

Evaluation of the Board and its Committees in 2024 - Formal evaluation with assistance from an external

consultant

In late 2024 and early 2025, a formal evaluation was conducted under the direction of the Appointments, Governance and CSR

Committee, with assistance from a specialist consultancy firm. Various actions have been implemented to address the areas of

progress and vigilance identified in that evaluation:

Areas of progress and vigilance identified in 2024 evaluation	Actions implemented in 2025
Further reinforcement of oversight of the transformation of R&D, including use of AI	In 2025 , strategy seminars provided an opportunity for Board members to scrutinize R&D governance at Sanofi, and the ongoing transformation of the R&D function. In addition, Board members received a training module on the impacts and challenges around the use of AI in the biopharma sector, providing directors with relevant, up-to-date insights to enhance their review processes and the quality of their oversight over these major transformations.
Oversight of capital allocation, and progress on Business Development/ M&A strategy	The Board-level strategy seminar provided a forum for collective, in-depth thinking about long-term capital allocation priorities. From an operational perspective, the Board carried out an overhaul of the governance arrangements for Business Development and M&A, instigating a non-binding offer approval process, including thresholds geared to transaction size and formalizing the role of the Scientific Committee in decision-making.
Review of US operations	Directors had the opportunity to review Sanofi's US operations, including monitoring of the most favored nation (MFN) policy and signature of a voluntary agreement with the US administration, updates on tariffs and the supply chain situation, and mitigation plans to address political and commercial risks.
Strategy in China	The Board enhanced its strategic oversight of China by leveraging on the field trip made in December 2024, and a review of the report issued by the Scientific Committee on March 19, 2025. In response to China's repositioning towards leading-edge innovation, combined with the growing importance of China within Sanofi's external innovation portfolio, the Board signed off on an approach based on controlled integration with the local ecosystem.
In-depth review of succession planning and talent management	In 2025, the Appointments, Governance and CSR Committee carried out in-depth work on succession planning and talent management, with support from the Chief People Officer and an external recruitment consultancy firm. This gave Board members an opportunity for detailed scrutiny of potential successors for the CEO role, alongside related development plans to be rolled out over various time horizons from the short to the long term. The Board also reviewed emergency succession plans for the Chairman of the Board and for Patrick Kron, further enhancing corporate governance in terms of executive continuity.
Expanded training program for Board members, with at least three sessions to address (i) status of and trends in the US market, (ii) key principles of immunology, and (iii) equitable access to healthcare	Building on the training program initiated in 2024, Board members received training during 2025 on the topics identified in the 2024 evaluation (refer to "—Director Training" above).

Evaluation of the Board and its Committees in 2025 - Internal evaluation

In late 2025, an internal evaluation was conducted under the direction of the Appointments, Governance and CSR Committee,

based on a detailed questionnaire sent to each director. Each director was then provided with transcripts and a comprehensive

summary of the responses, based on which the Chairman conducted individual interviews with each director. Those interviews

took place in early 2026, providing an opportunity to assess the most important areas for improvement, prepare the Board

program for the coming year for approval, and provide individual feedback on the contributions of Board members.

The functioning of the Board was seen as improving, with no aspect regarded as having deteriorated year-on-year. In particular,

the transparency provided by external audits of the development pipeline and digital transformation was appreciated by the

Board as giving insights into Sanofi's progress in these two areas. The Board reaffirmed its keenness to focus its program even

more closely on key strategic issues and on R&D topics.

From that perspective, the contribution of certain committees to the work of the Board could nevertheless be improved. In

particular, the Scientific Committee could strengthen its oversight of R&D governance and productivity, and its contribution to

identifying long-term scientific opportunities, as part of more transparent dialogue with the R&D team. The Strategy Committee

could aim to achieve balance in its program between business development and M&A on the one hand, and longer- term thinking

around issues such as the impact of demographic factors and longevity, trends in the various markets in which the

pharmaceutical industry operates, and monitoring of the competitive landscape. The other committees were judged to be

functioning satisfactorily.

The areas of progress identified for 2026 , in line with those identified in 2025, a re:

• strengthening of R&D governance and productivity;

• capital allocation policy;

• oversight of digital transformation and the rollout of artificial intelligence;

• monitoring of implementation of Sanofi's strategy in China; and

• talent development and succession planning.

92 SANOFI FORM 20-F 2025

PART I
ITEM 6. Directors, Senior Management and Employees

The composition and size of the Board were regarded as appropriate. It was acknowledged that Sanofi has a relatively high

number of Board members compared to its peers, largely as a result of the presence of two employee representatives in

compliance with French legislation. Strengthening the Board's competencies in artificial intelligence and digital transformation, in

particular those relevant to the pharmaceutical sector, could be considered in the years ahead, along with a desire to marginally

reduce the size of the Board.

The Committee and the Board will continue to monitor diversity metrics, including on gender diversity, and will ensure that Sanofi

continues to meet its legal obligations.

B. Compensation

Compensation and other arrangements for corporate officers

Process for determining the compensation policy for corporate officers

The compensation policy for corporate officers is established by the Board of Directors, acting on the recommendation of the

Compensation Committee. The Board of Directors applies the AFEP-MEDEF Code when determining the compensation and

benefits awarded to our executive and non-executive corporate officers.

All members of the Compensation Committee are independent, and were chosen for their technical competencies and their

knowledge of current standards, emerging trends and Sanofi’s practices.

To fulfill their remit, the Committee regularly invites Sanofi’s Chief People Officer and Head of Reward and Performance to attend

their meetings. Committee members also work with the Chairman and the Secretary of the Board, who have contacts with our

principal institutional shareholders ahead of the Annual General Meeting.

In addition, the Chair or a member of the Committee:

• discusses the financial, accounting and tax impacts of the proposed compensation policy with the Chair of the Audit

Committee;

• plays an active role at meetings of the Appointments, Governance and CSR Committee and the Strategy Committee (to both

of which he/she belongs), thereby gaining assurance that the proposed performance criteria are consistent and appropriate in

light of Sanofi’s strategic ambitions.

The compensation policy is not subject to annual review, although some arrangements for implementing the policy – such as the

performance criteria applicable to the Chief Executive Officer’s annual variable compensation, for example – are defined by the

Board of Directors on an annual basis.

After consulting the Compensation Committee and as the case may be the other Board Committees, the Board of Directors may,

under the second paragraph of item III of Article L. 22-10-8 of the French Commercial Code, temporarily derogate from the

approved compensation policy for the Chief Executive Officer in exceptional circumstances and to the extent that the changes

are aligned with the corporate interest and necessary to safeguard the continuity or viability of Sanofi. Derogations from the

approved policy are possible in respect of the performance conditions applied to the Chief Executive Officer’s compensation,

and may result in either an increase or a decrease in compensation. Such derogations are possible in the event of a change in the

structure of the Sanofi group or major events affecting the markets. Such derogations may only be temporary and must be

properly substantiated.

Compensation policy for corporate officers

This section describes the compensation policy for corporate officers of Sanofi, as established pursuant to Article L. 22-10-8 of

the French Commercial Code. The compensation describes all the components of compensation awarded to corporate officers

of Sanofi as consideration for holding office, and explains the process by which it is determined, allocated, reviewed and

implemented.

Our compensation policy for corporate officers has three distinct elements: (i) the compensation policy for directors; (ii) the

compensation policy for the Chairman of the Board; and (iii) the compensation policy for the Chief Executive Officer.

Each of those policies is submitted for approval by our shareholders at the Annual General Meeting, in accordance with

Article L. 22-10-8 II of the French Commercial Code. The compensation policy approved in any given year applies to any person holding

a corporate office in that year. When a corporate officer is appointed between two Annual General Meetings, their compensation is

defined by applying the terms of the compensation policy approved by the most recent Annual General Meeting.

The compensation policy for Paul Hudson (C hief Executive Officer until end-of-day on February 17, 2026) for the period from

January 1, 2026 through February 17, 2026, is described below under "— Compensation policy for Paul Hudson". The

compensation policies for Olivier Charmeil (appointed as Interim Chief Executive Officer as of February 18, 2026) and Belén Garijo

(who will assume office as Chief Executive Officer after the Annual General Meeting of April 29, 2026) will be determined by the

Board of Directors at a later date, and included in a Report on Form 6-K that will also be published on the Sanofi corporate

website.

General principles and objectives

Our compensation policy is based on the following general principles:

• the policy must be simple;

• the policy must prioritize long-term performance;

• the level of compensation must be competitive, so that we can attract and retain talent; and

• there must be a fair balance between the corporate interest, the challenges of delivering on our strategy, and the

expectations of our stakeholders.

The Compensation Committee must ensure that trends in the compensation of corporate officers over the medium term are not

uncorrelated with trends in the compensation of all our employees. In terms of annual variable compensation and equity-based

compensation, the Compensation Committee aims to achieve convergence between the performance criteria applied to our

Senior Leaders and those applied to the Chief Executive Officer.

(1) Amounts paid to directors who held office for the entire year.

SANOFI FORM 20-F 2025 115

PART I
ITEM 6. Directors, Senior Management and Employees

Our equity-based compensation policy, which aims to align employee and shareholder interests and reinforce loyalty to Sanofi, is

a critical tool for our worldwide attractiveness as an employer.

Grantees of equity-based compensation plans (including our Chief Executive Officer) can only be awarded performance shares.

Awarding performance shares reduces the dilutive effect of equity-based compensation plans while maintaining the same level

of motivation for grantees.

Acting on the recommendation of the Compensation Committee, the Board of Directors determines the performance conditions

attached to equity-based compensation for all grantees at Sanofi and its subsidiaries worldwide, thereby furthering the

attainment of our objectives.

The Board of Directors makes any grant of performance shares contingent on multiple, exacting multi-year performance criteria

in order to ensure that our equity-based compensation plans incentivize overall performance. Failure to achieve those criteria

over the entire performance measurement period results in a reduction or loss of the initial grant.

In order to align equity-based compensation with our long-term performance, performance is measured over three financial

years (the “vesting period”). Awards of performance shares are also contingent on continued employment in the Sanofi group

during the vesting period, followed by stringent lock-up obligations in the case of the Chief Executive Officer (see below).

The terms of prior awards cannot be reset subsequently, for instance with less exacting performance conditions.

Compensation policy for directors

Directors hold office for a four-year term, as specified in our Articles of Association (except in the event of staggered terms). They

may be removed from office by a shareholders’ meeting, at any time and without restriction.

The maximum annual amount of overall compensation allocated to the directors wa s set at €2,500,000 by the Annual General

Meeting of May 25, 2023. The average compensation per director (1) was approximately €164,520 in 2024, and approximately

€178,205 in 2025. Almost all of that maximum annual amount was paid out in 2024, while in 2025 the maximum annual amount

was exceeded such that directors' entitlement to compensation had to be apportioned on a pro rata basis, and they received

4.14% less compensation than they should have done.

At the end of 2025, the Compensation Committee decided to review the allocation mechanism and to recalibrate the maximum

annual amount, to ensure that it was fit for purpose.

The Committee conducted a benchmarking exercise involving (i) a panel of the twelve leading global pharmaceutical

companies (2) , which showed a significant gap in compensation, and (ii) companies in the French CAC 40 index. Those two peer

groups were chosen by the Committee so as to obtain a rounded and relevant overview of market practices. The benchmarking

exercise, conducted on the basis of 2024 data, showed that:

• The maximum overall annual amount allocated to Sanofi directors was below the average for the twelve leading global

pharmaceutical companies (€3,585,827), as was the average compensation per director (€211,931 for the panel, compared to

€161,770 per Sanofi director), bearing in mind also that the average per director varied between regions:

– (i) €322,591 for companies based in the US, (ii) €379,830 for companies based in Switzerland, and (iii) €202,106 for

companies based in the EU and the UK.

• The maximum overall annual amount allocated to Sanofi directors was the third highest in the CAC 40 (average: €1,476,528),

even though Sanofi averages more Board members (16) than the CAC 40 (12), and the average annual compensation per

director was the fifth highest in the CAC 40 (average: €112,770, versus €164,520 for a Sanofi director).

The Compensation Committee also assessed specific issues around attractiveness, and the retention of people with the right

profile for Board membership in the pharmaceutical industry:

• The need to maintain compensation at a competitive level, given that Sanofi has to be able to attract and retain Board

members with the unusual skillsets and competencies required for a proper understanding of the pharmaceutical industry.

• The fact that directors' compensation at Sanofi has not been reviewed for several years. The fixed portion of €30,000 has not

changed since 2016, and the amount of compensation per meeting (€5,500 for a director resident in France) since 2019.

Finally, the Compensation Committee considered the changing workload of directors, and the increasing complexity of the work

of the Board and its committees:

• The need to reflect the increased workload of the Board and its committees, which has become apparent in recent years and

is likely to remain high in future. To facilitate dynamic decision-making in a fast-moving business context (especially in terms

of reviewing divestments and acquisitions, and monitoring progress on the R&D pipeline), Board practices have evolved

towards more frequent meetings (more than 10 Board meetings a year since 2022). In addition, a steady rise in the number of

committee meetings was seen in 2025, especially for the Scientific Committee (11 meetings in 2025, comp ared with 6 in 2024).

• The increasingly complex geopolitical situation, which has triggered major transformations in the pharmaceutical industry.

(3) AstraZeneca plc, Bayer AG, GlaxoSmithKline plc, Novo Nordisk A/S.

(4) Average total overall allocation of €3,585,827, and average compensation per director of €302,300.

116 SANOFI FORM 20-F 2025

PART I
ITEM 6. Directors, Senior Management and Employees

Based on the findings above, the Board of Directors - on a recommendation from the Compensation Committee - has decided to

change the allocation mechanism for directors' compensation with effect from 2026 by (i) increasing the fixed portion from

€30,000 to €37,500 for all directors and (ii) raising the amount of compensation per meeting by €1,000 per Board meeting, by

€500 per committee meeting, and by €1,000 per meeting for committee chairs.

To allow for that change in the allocation mechanism, the Board of Directors will ask the Annual General Meeting of April 29, 2026

to approve an increase in the maximum annual amount of overall compensation allocated to the directors with effect from the

2026 financial year, from the current €2,500,000 to €3,200,000. That would take the maximum annual overall amount to the

highest ranking in the CAC 40, and raise both the maximum annual amount and the average compensation per director (which

would be €213,000) to a level comparable with the averages computed for global pharmaceutical companies headquartered in

Europe (EU and UK, but excluding Switzerland which has specific characteristics) (3) , while nonetheless remaining below the

average level of directors' compensation for the twelve leading global pharmaceutical companies (4) .

The new allocation mechanism would still be in compliance with the AFEP-MEDEF Code, which requires directors' compensation

to be allocated predominantly on a variable basis.

The table below shows how the variable amount payable to directors for attendance at Board and committee meetings will be

determined with effect from 2026, s ubject to approval of the compensation policy by the next Annual General Meeting of Sanofi

shareholders:

	Compensation per meeting — Directors resident in France	Directors resident outside France but within Europe	Directors resident outside Europe	Chair
Board of Directors	€6,500	€9,250	€12,000	N/A
Audit Committee	€8,750	€11,500	€14,250	€14,750
Compensation Committee	€6,000	€8,750	€11,500	€12,000
Appointments, Governance and CSR Committee	€6,000	€8,750	€11,500	€12,000
Strategy Committee	€6,000	€8,750	€11,500	N/A
Scientific Committee	€6,000	€8,750	€11,500	€12,000

The distinction between directors resident within or outside Europe is intended to reflect the significantly longer travel time

required to attend Board meetings in person.

Directors who take part via videoconference receive compensation equivalent to that paid to a director resident in France

attending in person, except for committee chairs who continue to receive the usual compensation in respect of the committee

they chair.

As an exception, in certain cases two meetings held on the same day give entitlement only to a single payment:

• if on the day of a Shareholders’ General Meeting, the Board of Directors meets both before and after the meeting, only one

payment is made for the two Board meetings; and

• if on the same day a director participates in a meeting of the Compensation Committee and a meeting of the Appointments,

Governance and CSR Committee, only the higher of the two payments is made to cover both meetings.

Since 2025, attendance at a meeting that does not last for more than 60 minutes does not automatically give entitlement to

compensation; Board members must have accumulated at least two and a half hours of attendance at meetings before they

receive compensation.

Directors do not receive any exceptional compensation or equity-based compensation and have no entitlement to a top-up

pension plan.

Neither the Chairman of the Board nor the Chief Executive Officer receives any compensation for serving as a director.

Compensation policy for the Chairman of the Board of Directors

The term of office of the Chairman of the Board is the same as that of the other directors (four years), and the Chairman’s term is

aligned with his term of office as a director. He may be removed from office at any time by the Board of Directors.

The compensation policy for the Chairman of the Board of Directors is discussed by the Compensation Committee, which then

makes a recommendation to the Board of Directors. The Chairman of the Board is not a member of the Committee, and does not

attend meetings where his compensation is discussed.

The compensation of the Chairman of the Board of Directors (where the office of Chairman is separate from that of Chief

Executive Officer, as is currently the case) consists solely of fixed compensation and benefits in kind and excludes any variable or

exceptional compensation, any awards of stock options or performance shares, and any compensation for serving as a director.

The annual fixed compensation awarded to the Chairman of the Board of Directors is €880,000 gross. That amount was set at

the Board meeting of February 22, 2023, and has not changed since May 25, 2023 (the date on which the current Chairman took

office).

(5) Studies carried out on the basis of figures disclosed by the companies, supplemented by analyses conducted by Pay Governance and Boracay.

Sanofi's ranking within the panel is based on an ex ante analysis of target compensation and ex ante theoretical maximum compensation, incorporating

(i) base salary applicable for the 2025 financial year as approved by a shareholder meeting, or (failing that) the most recently published base salary;

(ii) annual bonus (target and maximum); and (iii) long-term incentive plan awards (target and maximum theoretical levels), as specified in compensation

policies.

For 2025 long-term incentive plans, in cases where no IFRS fair value has been disclosed to date for 2025 plan awards, the valuation used relies on an ex

ante assumption based on the target level of awards specified by the 2025 ex ante compensation policy or (failing that) using a benchmark methodology

based on the valuation of the plan awarded in respect of the previous financial year.

The analysis relative to the CAC 40 panel relies on a valuation of long-term incentive plan awards expressed in IFRS fair value terms at the date of grant,

in accordance with market practices applicable to French companies.

The analysis relative to the global panel relies on a valuation of long-term incentive plan awards expressed at (i) face value in the case of awards of

performance shares and Restricted Stock Units (target number of shares, multiplied by the closing quoted share price on the date of grant) and (ii) fair

value for accounting purposes in the case of stock options, as disclosed by the companies in accordance with US market practices.

SANOFI FORM 20-F 2025 117

ITEM 6. Directors, Senior Management and Employees

This amount takes account of the specific remit of the Chairman of the Board of Directors as described in the Sanofi Board

Charter, and of his membership of three Board Committees (the Strategy Committee, which he chairs; the Appointments,

Governance and CSR Committee; and the Scientific Committee).

The compensation of the Chairman of the Board of Directors is not subject to annual review.

Where the office of Chairman is separate from that of Chief Executive Officer, the Chairman of the Board is not entitled to the

Sanofi top-up defined-contribution pension plan.

Nor is he entitled to a termination benefit or a non-compete indemnity.

Compensation policy for Paul Hudson

General principles

Paul Hudson, our Chief Executive until end-of-day February 17, 2026, did not have a fixed term of office and could be removed

from office on legitimate grounds at any time by the Board of Directors.

The compensation policy for the Chief Executive Officer is established by the Board of Directors, acting on the recommendation

of the Compensation Committee. The compensation structure is not subject to annual review and is applicable for as long as it

remains unchanged. The arrangements for implementing the policy may vary from year to year; a table showing the changes

made to those arrangements in 2026 and 2025 is provided at the end of the present section. The components of the Chief

Executive Officer's compensation as determined by the Board of Directors for 2026 are described below, in the section ent itled

"—Compensation and benefits of all kinds awardable to corporate officers in respect of 2026 " below. That section forms an

integral part of the compensation policy of the Chief Executive Officer for 2026 that will be submitted for approval by the Annual

General Meeting.

The Chief Executive Officer's overall compensation is determined with reference to (i) experience and key stakeholder

expectations and (ii) practices adopted by (a) a panel of CAC 40 companies and (b) a panel of pharmaceutical companies with

which Sanofi is in competition. Because Sanofi operates in a particularly competitive international environment and has broad

geographical reach (with over three-quarters of its net sales generated in the US and non-European countries), a panel is used

comprising the Chief Executive Officer compensation of 12 leading global pharmaceutical companies with comparable levels of

net sales to Sanofi, but with no limitation as to geography. That panel has remained unchanged since 2020.

This consistency with market practice is fundamental in order to attract and retain the talents necessary to our success, but does

not imply that Sanofi should adopt in every respect practices that are in some cases widely divergent, especially as regards the

level of long term compensation.

Market practice based on a panel of 14 CAC 40 companies

Local practices are reviewed by reference to a panel of 14 CAC 40 companies with a comparable profile to Sanofi in terms of

market capitalization, net sales, market presence, return on capital employed, etc; the panel was selected with assistance from an

external consultant (5) . This study showed that Sanofi ranks seventh among the panel in terms of market capitalization, and ninth in

terms of net sales.

equal fourth within the panel, and his ex ante target short-term compensation (fixed plus target variable) ranks fifth. His target ex

ante equity-based compensation ranks fourth within the panel, largely because our Compensation Committee takes some

account of practices adopted by our pharmaceutical industry competitors (see below). His ex ante target overall compensation

(fixed, variable and equity-based) also ranks fourth within the panel. Finally, his ex ante theoretical maximum overall

compensation, due under the compensation policy in the event of outperformance of the maximum attainment levels, ranks fifth

within the panel.

(6) Some companies do not disclose target equity-based compensation.

(7) Actual total compensation represents the sum total of (i) fixed compensation actually paid, (ii) variable compensation paid, (iii) gains arising from exercise

of stock options, and (iv) the value of shares acquired at the end of the vesting period. The analysis covers the years 2022, 2023 and 2024. For US

companies, the value of acquired shares is derived from Stock Vested disclosures in annual report filings; for non-US companies, it is derived from actual

compensation or final allocation disclosures. Roche Holding AG was excluded from the analysis because it does not disclose this information.

This study showed that Sanofi ranks tenth among the panel in terms of market capitalization, and eighth in terms of net sales.

Based on an ex ante analysis of this panel, for 2025 the fixed compensation of our Chief Executive Officer ranks eighth within the

panel, as does his target short-term compensation (fixed+variable). His theoretical maximum equity-based compensation ranks

eleventh (6) . His ex ante theoretical maximum overall compensation (fixed, variable and equity-based) ranks twelfth within the

panel, and his ex ante theoretical target overall compensation ranks eleventh.

In addition, an analysis of actual total compensation for the 2022-2024 period places our Chief Executive Officer at the second

lowest ranking within the panel, and hence in the lowest quartile of the sample (7) .

Approval of the compensation policy of the Chief Executive Officer for 2025 by the Annual General Meeting of

April 30, 2025

Following a review of the structure of the Chief Executive Officer's compensation package, the Board meeting of

February 12, 2025, acting on a recommendati on from the Compensation Committee, decided to (i) raise the Chief Executive

Officer's annual fixed compensation to €1,600,000 , and (ii) increase the quantum of his allocation of equity-based compensation

for 2025 subject to the ceiling set by the compensation policy. In addition, to reinforce (i) alignment between the respective

interests of Sanofi, the Chief Executive Officer and our shareholders and (ii) the stringent nature of the performance conditions,

the weighting of the Total Shareholder Return (TSR) criterion for the Chief Executive Officer's performance share plan was raised

from 20% to 30% with effect from 2025. The other components of the Chief Executive Officer's compensation were unchanged.

The fifteenth resolution (referring to approval by the April 30, 2025 Annual General Meeting of the compensation policy for the

Chief Executive Officer) was approved with 75.36% of the votes cast.

The Compensation Committee meeting of October 21, 2025 reviewed the results of the votes cast, along with comments made

both before and after the Annual General Meeting, including discussions between the Chairman of the Board and a shareholder

panel representing approximately 30% of Sanofi's share capital. This enabled the Chairman of the Board to gauge not only the

sensitivity but also the divergent opinions among the shareholder base around the issue of increases in executive compensation.

The main reservations expressed were:

• the theoretical overall quantum of post-increase compensation: some investors adopt an approach narrowly aligned on the

specific context around executive pay in France, while others took the view that the quantum of compensation is an incentive

that drives success, especially given the specific nature of the pharma industry and the profile of Sanofi's principal

competitors;

• the timing of the increase on the part of our Board of Directors, three years after the previous increase: some investors favor

more regular reviews of fixed compensation, while others make the case for a longer interval between reviews;

• the Compensation Committee's decision to benchmark using target compensation: some investors saw this as a robust

approach given the equity-based compensation structure adopted by Sanofi (which does not allow for over-allocation at the

end of the vesting period), while others objected to this methodology and the associated level of transparency;

• the structure of equity-based compensation plans that allow for offset between criteria; and

• lack of transparency around performance objectives for confidentiality reasons, especially concerning (i) the thresholds set for

attaining of the objectives for annual variable compensation and equity-based compensation and (ii) the CSR objectives,

which are not sufficiently detailed.

Those concerns highlight the difficulties our Board of Directors faces in reconciling the expectations of all our investors, who are

constrained by strict - and sometimes contradictory - voting policies.

After taking into account the views expressed by shareholders, the Board meeting of October 23, 2025, on a recommendation

from the Compensation Committee, decided in the interests of transparency to implement the following improvements:

• the narrative in the report on compensation regarding the use of benchmarks has been reviewed, and information is provided

to a greater degree of granularity, thereby expectations of shareholders and proxy advisers by making it clearer and easier to

understand;

• the transparency of our performance objectives (especially our CSR objectives) has been enhanced, again in line with the

expectations of shareholders and proxy advisers; and

• in terms of the structure of equity-based compensation plans, the Board takes the view that the current compensation

arrangements can be retained given that (unlike for most of the companies in the pharma sector peer panel) the number of

shares delivered at the end of the vesting period cannot exceed the number of shares awarded (100% cap), thereby striking a

balance between the need to compensate our Chief Executive Officer commensurately with his actual performance on the

one hand, and avoiding excess vesting levels decoupled from the interests of shareholders.

SANOFI FORM 20-F 2025 119

PART I
ITEM 6. Directors, Senior Management and Employees

The Chairman of the Board of Directors and senior members of our team have in recent years engaged in constant, constructive

dialogue with shareholders; this approach will be maintained, to ensure we listen to shareholders' views on compensation policy.

On taking up office

When the Chief Executive Officer is an outside appointment, the Board of Directors may decide, acting on a recommendation

from the Compensation Committee, to compensate the appointee for some or all of the benefits he may have forfeited on

leaving his previous employer. In such a case, the terms on which the Chief Executive Officer is hired aim to replicate the diversity

of what was forfeited, with a comparable level of risk (variable portion, medium-term equity-based or cash compensation).

During the term of office

Compensation structure

Our policy aims at achieving and maintaining a balance in the compensation structure between fixed compensation, benefits in

kind, short-term variable cash compensation, and medium-term variable equity-based compensation.

The compensation policy for the Chief Executive Officer is designed to motivate and reward performance by ensuring that a

significant portion of compensation is contingent on the attainment of financial, operational and extra-financial criteria that

reflect Sanofi’s objectives, and are aligned with the corporate interest and with the creation of shareholder value. Variable cash

compensation and equity-based compensation are the two principal levers for action, and are intended to align the interests of

the Chief Executive Officer with those of our shareholders and stakeholders.

During the meeting that follows the Board meeting held to close off the financial statements for the previous year, the

Compensation Committee examines the levels of attainment of variable compensation for that year. In advance of that meeting,

the Chief Executive Officer presents the Committee with a report containing narrative and quantitative information necessary to

measure attainment of the objectives. The members of the Compensation Committee then discuss the information provided and

report to the Board on those discussions, giving an evaluation of the Chief Executive Officer’s performance against each of the

criteria (determining the level of attainment for quantitative objectives, and evaluating the level of attainment for qualitative

objectives compared to the objectives set at the beginning of the year).

Annual fixed compensation

The annual fixed compensation of the Chief Executive Officer has been set at €1,600,000 gross with effect from 2025.

The amount of fixed compensation is not subject to annual review. It may however be changed, provided that such changes are

not material:

• on the appointment of a new Chief Executive Officer, to reflect the new appointee’s competencies and/or then current

market practice; and

• in exceptional circumstances, to take account of changes in (i) the role or responsibilities of the Chief Executive Officer, for

e xample in terms of market conditions or the size of the Sanofi group or (ii) the performance level of Sanofi over a given period.

Annual variable compensation

Annual variable compensation is in a range between 0% and 250% of fixed compensation, with a target of 150%. It is subject to

a range of varied and exacting performance criteria, both quantitative and qualitative. The criteria are reviewed annually in light

of the strategic objectives determined by Sanofi. The Board of Directors sets the criteria for each year at the start of that year,

acting on a recommendation from the Compensation Committee.

For 2026 , the criteria determined at the Board meeting of February 11, 2026 are:

• 60% based on financial indicators published by Sanofi: sales growth, free cash flow (FCF) and business earnings per share

(business EPS), each accounting for 20%; and

• 40% based on specific individual objectives: Portfolio & Assets (7.5%); Digital Transformation and Artificial Intelligence (7.5%);

R&D Pipeline (15%); and Corporate Social Responsibility (10%). The individual objectives set for variable remuneration for 2026

are described in “— Compensation and benefits of all kinds awardable to corporate officers in respect of 2026 ” below.

Although for each of those financial criteria the Board of Directors (acting on a proposal from the Compensation Committee) has

set specific objectives, those objectives cannot be disclosed for confidentiality reasons. Nevertheless, to align on shareholder

expectations Sanofi provides ex-post disclosures for each financial criterion, showing key thresholds within the range of

outcomes that enable attainment levels for the past financial year to be calculated (see “— Compensation and benefits of all

kinds paid during 2025 or awarded in respect of 2025 to Paul Hudson” below).

The percentage of variable compensation linked to the attainment of quantitative criteria may be scaled down regardless of

actual performance, in order to give greater weight to the attainment of qualitative criteria. This flexibility can only operate to

reduce the amount of variable compensation, and cannot compensate for underperformance on quantitative criteria.

Payment of annual variable compensation in a given year in respect of the previous year is contingent on a favorable shareholder

vote at the Annual General Meeting.

ITEM 6. Directors, Senior Management and Employees

Equity-based compensation

The Chief Executive Officer’s equity-based compensation can only be awarded in the form of performance shares, and his

allocation is determined in terms of the number of shares rather than by value. It cannot be reviewed annually, and may represent

up to 250% of his target short-term compensation (fixed plus variable).

The Chief Executive Officer’s equity-based compensation is contingent upon attainment of exacting performance conditions, all

of them quantitative, measured over a three-year-period. Such awards ar e contingent both upon internal criteria (financial and

extra-financial) and external criteria.

As indicated in our currently applicable performance share plans, our Board of Directors reserves the right to adjust, both

upwards and downwards and within the limits of policy, the performance conditions in exceptional circumstances justifying such

an adjustment (if the Compensation Committee so advises), and specifically in the event of (i) a change in the structure of the

Sanofi group, (ii) a change in accounting policy, or (iii) any other circumstances that would justify such an adjustment, in the

opinion of our Board of Directors. The purpose of such an adjustment would be to ensure that the results of applying

performance conditions reflect the above-mentioned changes. Any such adjustments would be justified and disclosed ex-post in

our annual report on Form 20-F.

Acting on a proposal from the Compensation Committee, the Board of Directors has sought to maintain common criteria for

annual variable compensation and equity-based compensation, in order to ensure that short-term performance does not come

at the expense of long-term performance.

The valuation of performance shares is calculated at the date of grant, weighted between (i) fair value determined using the

Monte Carlo model and (ii) the market price of Sanofi shares at the date of grant, adjusted for dividends expected during the

vesting period.

Each award to our Chief Executive Officer takes into account previous awards and his overall compensation. In any event, the

maximum number of shares to be delivered may not be more than the number of performance shares initially awarded.

Given the decision by our Board of Directors to relieve Paul Hudson of his duties as Chief Executive Officer effective end-of day

on February 17, 2026, it has been decided that he would not been awarded any performance shares in respect of 2026 .

Share ownership and lock-up obligation of the Chief Executive Officer

The Chief Executive Officer is bound by the same obligations regarding share ownership specified in our Articles of Association

and Board Charter as our other corporate officers.

In addition, the Chief Executive Officer is bound by an obligation to retain, until he ceases to hold office, a quantity of Sanofi

shares corresponding to 50% of the capital gain (net of taxes and social contributions) arising on the vesting of his shares,

calculated as of the date on which they vest. Those shares must be held in registered form until he ceases to hold office.

In compliance with the AFEP-MEDEF Code and our Board Charter, the Chief Executive Officer must undertake to refrain from

entering into speculative or hedging transactions.

Multi-year variable compensation

The Chief Executive Officer does not receive multi-year variable compensation.

Compensation for serving as a director

Executive officers of Sanofi do not receive any compensation for serving as directors. Consequently, the Chief Executive Officer

does not receive compensation in his capacity as a director or as a member of the Strategy Committee.

Exceptional compensation

No exceptional compensation can be awarded to the Chief Executive Officer.

On leaving office

The Chief Executive Officer is entitled to a top-up defined-contribution pension plan, a termination benefit, and a non-compete

indemnity.

Such arrangements are part of the overall compensation package generally awarded to executive officers; in line with the

recommendations of the AFEP-MEDEF code, there are very strict rules about how they are implemented. The termination benefit

and non-compete indemnity are intended to compensate for the fact that the Chief Executive Officer may be dismissed at any

time.

Each of those benefits is taken into account by the Board of Directors when fixing the overall compensation of the Chief

Executive Officer.

Given the decision by our Board of Directors to relieve Paul Hudson of his duties as Chief Executive Officer effective end-of-day

on February 17, 2026, he will receive a termination benefit and a non-compete indemnity. The financial terms of Paul Hudson's

termination arrangements will be communicated in a Report on Form 6K and published on Sanofi's corporate website, that will

also include the compensation policies for Olivier Charmeil (appointed as Interim Chief Executive Officer as of February 18, 2026)

and Belén Garijo (who will assume office as Chief Executive Officer after the Annual General Meeting of April 29, 2026.

SANOFI FORM 20-F 2025 121

ITEM 6. Directors, Senior Management and Employees

Pension arrangements

The Chief Executive Officer is entitled to benefits under the top-up defined-contribution pension plan introduced within Sanofi

on January 1, 2020. This is a collective plan falling within the scope of Article 82 of the French General Tax Code. It is also offered

to members of our Executive Committee and to all senior executives whose position is classified within the Sanofi grade scale

as “Executive Level 1 or 2”. The Chief Executive Officer’s entitlement under this plan may be withdrawn by a decision of the Board

of Directors, but not retroactively.

Under the terms of the plan, the Chief Executive Officer receives an annual contribution the amount of which (subject to

attainment of a performance condition) may be up to 25% of his reference compensation (annual fixed and variable cash-based

compensation only; all other compensation is excluded). The rights accruing under the plan are those that are generated by the

capitalization contract taken out with the insurer, and vest even if the Chief Executive Officer does not remain with Sanofi until

retirement. The Chief Executive Officer may elect for the rights to be transferable as a survivor’s pension.

The performance condition is as follows:

• if the level of attainment for variable compensation is equal to or greater than the target (i.e. 150% of fixed compensation),

100% of the contribution is paid;

• if the level of attainment for variable compensation is less than 100% of fixed compensation, no contribution is paid; and

• between those two limits, the contribution is calculated on a pro rata basis.

Because this performance condition is linked to the attainment of the performance criteria for annual variable compensation

(which itself is determined with reference to the strategic objectives of Sanofi), it ensures that no pension contributions could be

made in the event that the Chief Executive Officer fails to deliver.

The plan is wholly funded by Sanofi, which pays the full amount of the gross contributions. Because it is treated as equivalent to

compensation, the contribution is subject to payroll taxes and employer’s social security charges, and to income tax in the hands

of the Chief Executive Officer; all of the above are charged on the basis of the bands, rates and other conditions applicable to

compensation, and paid and declared on his pay slips for the contribution period.

Subject to (i) formal confirmation by the Board of Directors that the performance condition for the previous year has been met

and (ii) approval of the Chief Executive Officer’s compensation package for that year by the Annual General Meeting of our

shareholders, the annual gross contribution is paid as follows:

• 50% as a gross insurance premium to the fund manager; and

• 50% to the Chief Executive Officer, to indemnify him for the social security and tax charges for which he will become

immediately liable.

In accordance with Article 39.5 bis of the French General Tax Code, deferred compensation as defined in section 4 of

Article L. 22-10-9.4 of the French Commercial Code can be offset against corporate profits as a taxable expense up to a limit set

at three times the annual social security ceiling per beneficiary.

The pension entitlement is not cumulative with (i) any termination benefit paid in the event of forced departure or (ii) any

non-compete indemnity.

Termination arrangements

The termination benefit only becomes payable if the departure of the Chief Executive Officer is forced, i.e. in the event of

removal from office or resignation linked to a change in strategy or control of Sanofi. Compensation for non-renewal of the term

of office is irrelevant in the case of the Chief Executive Officer, because this office is held for an indefinite term.

In addition, no termination benefit is payable and the arrangement is deemed to have been rescinded in the following

circumstances:

• removal from office for gross or serious misconduct (faute grave ou lourde) ;

• if the Chief Executive Officer elects to leave Sanofi to take up another position;

• if the Chief Executive Officer is assigned to another position within Sanofi; or

• if the Chief Executive Officer takes his pension.

Payment of the termination benefit is contingent upon fulfillment of a performance condition, which is deemed to have been met

if the attainment rate for the individual variable compensation objectives exceeded 90% of the target; that condition is assessed

over the three financial years preceding the Chief Executive Officer leaving office.

The amount of the termination benefit is capped at 24 months of the Chief Executive Officer’s most recent total compensation

on the basis of (i) the fixed compensation effective on the date of leaving office and (ii) the last variable compensation received

prior to that date subject to fulfillment of the performance condition.

The amount of the termination benefit is reduced by any amount received as consideration for the non-compete undertaking,

such that the aggregate amount of those two benefits may never exceed two years of total fixed and variable compensation.

ITEM 6. Directors, Senior Management and Employees

Non-compete undertaking

In the event of his departure from Sanofi, the Chief Executive Officer undertakes, during the 12-month period following his

departure, not to join a competitor of Sanofi as an employee or corporate officer, or to provide services to or cooperate with such

a competitor.

In return for this undertaking, he receives an indemnity corresponding to one year’s total compensation, based on his fixed

compensation effective on the day he leaves office and on the last individual variable compensation he received prior to that

date. This indemnity is payable in 12 monthly installments.

However, the Board of Directors reserves the right to release the Chief Executive Officer from that undertaking for some or all of

that 12-month period. In such cases, the non-compete indemnity would not be due for the period of time waived by the

Company.

Consequences of the Chief Executive Officer’s departure for equity-based compensation

If the Chief Executive Officer leaves Sanofi for reasons other than resignation or removal from office for gross or serious

misconduct (in which case any award of equity-based compensation is forfeited in full), the overall allocation percentage is

prorated to reflect the amount of time the Chief Executive Officer remained with Sanofi during the vesting period.

If at any time prior to the expiration of the vesting period of his performance shares the Chief Executive Officer joins a competitor

of Sanofi as an employee or corporate officer, or provides services to or cooperates with such a competitor, he irrevocably loses

those performance shares regardless of any full or partial discharge by the Board of Directors of the non-compete undertaking

relating to his office as Chief Executive Officer.

If the Chief Executive Officer retires at the statutory retirement age prior to the expiration of the vesting period of his

performance shares, the overall allocation rate will be apportioned on a pro rata basis to reflect the amount of time for which the

Chief Executive Officer remained in the employment of Sanofi during the vesting period.

Summary of benefits awarded to the Chief Executive Officer on leaving office

The table below presents a summary of the benefits (as described above) that could be claimed by the Chief Executive Officer on

leaving office, depending on the terms of his departure. The information provided in this summary is without prejudice to any

decisions that may be made by the Board of Directors.

aggregate amount of those two benefits may never exceed two years of total fixed and variable compensation.

(b) The Board of Directors may decide to release the Chief Executive Officer from the non-compete undertaking for some or all of the 12-month period. In

that case, the non-compete indemnity would not be due, or would be scaled down proportionately.

Policy to recover erroneously-awarded compensation (“clawback”)

In 2023, the NASDAQ listing rules were amended to include Rule 5608, in application of Section 10D-1 of the Securities Exchange

Act of 1934 which requires listed companies to implement a c lawback policy.

On October 26, 2023, our Board of Directors adopted a clawback policy under which Sanofi must, within a reasonable

time-frame, recover the portion of the Chief Executive Officer’s variable compensation (cash-based or equity-based) that is

wholly or partly contingent on the attainment of financial performance criteria and was paid to him (according to the definition

contained in the NASDAQ listing rules) based on financial information that has been determined to be erroneous and has required

accounting restatement to correct an error in previously-published financial statements. The policy applies to compensation paid

on or after October 2, 2023.

The clawback policy also applies to members of our Executive Committee and to our Head of Consolidation (equivalent to the

Chief Accounting Officer within the meaning of the NASDAQ listing rules).

Summary of changes made to the compensation policy f or Paul Hudson

The table below summarizes adjustments made to the compensation policy for the Ch ief Executive Officer and to the content of

the information published in the compensation report, some of which have been discussed in depth with our shareholders.

2026

2025

• Annual variable compensation: – Narrative explanations of the use of benchmarks reviewed, and information provided to a higher degree of granularity. – Transparency of performance objectives, especially CSR objectives, enhanced

• Annual fixed compensation: – Annual fixed compensation is increased from €1,400,000 to €1,600,000 gross starting from 2025. • Equity-based compensation: – Given the increase in the number of performance shares awarded to the Chief Executive Officer in respect of 2025, increase in the weighting of the TSR criterion from 20% to 30%. To enable the TSR weighting to increase to 30%, the Business EPS weighting was reduced from 35% to 30%, and the Free Cash Flow weighting from 25% to 20%; the R&D and CSR criteria remained unchanged. Furthermore, in order to align with market practices, the Board of Directors decided to review the mechanism so as to reward Sanofi's relative positioning vis-à-vis the peer panel. • Transparency on performance criteria applicable to annual variable compensation: – Greater transparency on the financial performance criteria applicable to annual variable compensation: information about the thresholds (floor, target and maximum attainment level) used by the Board of Directors to determine the overall attainment level and payout is now published for each criterion.

Compensation and benefits of all kinds paid during 2025 or awarded in respect of 2025 to corporate officers

The section below constitutes the report on compensation of corporate officers required by Articles L. 225-37 and L. 22-10-8 of

the French Commercial Code. The arrangements described therein will be submitted for approval by our shareholders at the

Co mpensation elements and benefits of all kinds paid during 2025 or awarded in respect of 2025 to directors

The compensation policy for directors (as described above in the section entitled “— Compensation policy for directors”) defines

the fixed amount of compensation, and the principles for allocating the variable portion between directors, up to the limit of the

overall amount approved by the Annual General Meeting.

Directors’ compensation includes an annual fixed payment, apportioned on a time basis for directors who assumed or left office

during the year; and a variable amount, allocated by the Board according to actual attendance at Board and Committee

Fixed and variable compensation

Acting on a recommendation from the Compensation Committee, the Board meeting of February 11, 2026 determined the

components of Paul Hudson’s compensation for the 2025 financial year.

In accordance with the compensation policy for the Chief Executive Officer as approved by the Annual General Meeting of

Sanofi's shareholders on April 30, 2025 , his annual compensation for 2025 comp rises (i) annual fixed gross compensation of

€1,600,000 ; and (ii) annual variable compensation in a range from 0% to 250% of his annual fixed compensation, with a target of

150%, and subject to both quantitative and qualitative criteria.

The objectives applicable to annual variable compensation in respect of 2025 were:

• 60% based on financial indicators: sales growth, FCF and Business EPS, each accounting for 20%; and

• 40% based on specific individual objectives. For 2025 , the individual objectives set by the Board were:

– business transformation (15%) – quantitative and qualitative objective;

– development pipeline (15%) – quantitative objective; and

– CSR (10%) – quantitative and qualitative objective.

In the interests of transparency, Sanofi discloses, for each financial criterion, information about the thresholds (floor, target and

maximum attainment level) used by the Board of Directors to determine the overall attainment level and payout in respect of the

past financial year.

Objective	Measured against	Payout — Threshold (floor) Payout = 0%	Target (X, in %) Payout = 100%	Maximum payout = 166.67%
		Attainment level
Sales growth	Growth versus 2025 budget	X -4 percentage points	100%	X +4 percentage points
Business EPS	Attainment level versus 2025 budget	X -5 percentage points	100%	X +5 percentage points
FCF	Growth versus 2025 budget	X -15 percentage points	100%	X +50 percentage points

Likewise, at the start of each year, the Board of Directors establishes a precise matrix for determining each of the individual

objectives. Sanofi discloses the content of the qualitative criteria, accompanied by narrative for each sub-criterion explaining the

level of attainment reached. Those criteria are always assessed by reference to the performances of the leading global

pharmaceutical companies.

Sanofi also publishes such information for the People & Culture and Environment sub-criteria:

Objective	Measured against	Payout — Threshold (floor) Payout = 0%	Target (X, in %) Payout = 100%	Maximum payout = 150%
		Attainment level

(a) In 2025, it was agreed that for the purpose of calculating the attainment of quantitative criteria, the performance figures would be adjusted to

eliminate impacts related to (i) the acquisition of Blueprint and (ii) share buybacks; those adjustments negatively affected Sales Growth and Business

EPS.

Acting on a recommendation from the Compensation Committee, the Board meeting of February 11, 2026 set Paul Hudson’s

variable compensation for 2025 a t €2,616,000 gross, equivalent to 163.53% of h is fixed compensation.

Payment of Paul Hudson’s variable compensation in respect of the 2025 financial year is contingent on approval of his

compensation package by the shareholders in an Ordinary General Meeting, on the terms stipulated in Article L. 22-10-34 II of the

French Commercial Code.

Equity-based compensation

Using the authorization granted by our shareholders via the twentieth resolution of the Annual General Meeting of April 30, 2024,

the Board meeting held on April 30, 2025 decided, acting on the recommendation of the Compensation Committee, to award

Paul Hudson 90,000 performance shares in respect of 2025 . The valuation of that award as of April 30, 2025 , determined in

accordance with IFRS and incorporating a market-related condition, was €6,759,000 , equivalent to 4.22 times his fixed

compensation.

The entire amount of the award is contingent upon the attainment of performance objectives based on (i) internal criteria based

on business earnings per share (Business EPS), free cash flow (FCF), corporate social responsibility (CSR) and the R&D pipeline,

and (ii) an external criterion based on improvement in total shareholder return (TSR) relative to that of a benchmark panel of

12 leading global pharmaceutical companies (plus Sanofi): Amgen Inc., AstraZeneca plc, Bayer AG, Bristol-Myers Squibb Inc., Eli

Lilly and Company Inc., GlaxoSmithKline plc, Johnson & Johnson Inc., Merck & Co. Inc., Novartis AG, Novo Nordisk A/S, Pfizer Inc.,

and Roche Holding AG.

To align equity-based compensation on our medium-term performance, a three-year period ( 2025 - 2027 ) is used to measure

performance.

The above criteria were selected because they align medium-term equity-based compensation on the strategy adopted by

Sanofi.

The arrangements relating to these awards are as follows:

• The Business EPS criterion accounts for 30% of the award (Business EPS represents Sanofi's “business net income” divided by

the number of Sanofi shares), and is determined as the average actual-to-budget ratio of Business EPS attained over the

entire vesting period at constant exchange rates.

The objective cannot be less than the lower end of the range of the annual guidance announced publicly by Sanofi at the start

of each year. If the attainment level is less than 95%, no payment will be made for this criterion.

Business EPS actual-to-budget attainment level (B)	Business EPS allocation rate
If B < 95%	0%
If B = 95%	50%
If B is > 95% but < 98%	(50 + [(B - 95) x 16])%
If B is ≥ 98% but ≤ 105%	B%
If B is > 105% but < 110%	(105 + [(B - 105) x 3])%
If B is ≥ 110%	120%

(1) Amgen Inc., AstraZeneca plc, Bayer AG, Bristol-Myers-Squibb Inc., Eli Lilly and Company Inc., GlaxoSmithKline plc, Johnson & Johnson Inc., Merck & Co.

Inc., Novartis AG, Novo Nordisk A/S, Pfizer Inc., and Roche Holding AG. The Board of Directors may review the composition of the panel during the

measurement period in exceptional circumstances (dissolution or merger of a panel company).

(2) Historical values are adjusted for spin-offs, stock splits/reverse stock splits, scrip dividends/bonus issues, rights issues, etc.

SANOFI FORM 20-F 2025 131

PART I
ITEM 6. Directors, Senior Management and Employees

• The FCF criterion accounts for 20% of the award. This criterion was selected because it is aligned with Sanofi’s current

strategic objectives, and is transparent both within and outside the company.

The FCF criterion represents the average actual-to-budget FCF ratio attained over the entire period. The award is based on a

target FCF, below which some or all of the performance shares are forfeited; i f the attainment level is less than 70%, no

payment will be made for this criterion.

FCF actual-to-budget attainment level (F)	FCF allocation rate
If F is ≤ 70%	0%
If F is > 70% but < 80%	[(F - 70) x 5]%
If F = 80%	50%
If F is > 80% but < 100%	(50 + [(F – 80) x 2.5])%
If F = 100%	100%
If F is > 100% but < 120%	F%
If F is ≥ 120%	120%

• The TSR criterion accounts for 30% of the award. This performance criterion compares Sanofi's three-year TSR performance

with the median TSR of comparable companies included in a peer panel of 12 pharmaceutical companies (1) over the same

period. Sanofi's TSR corresponds to the performance of the Sanofi share price (2) uplifted by dividends per share during the

measurement periods, without reinvestment.

TSR calculation

The TSR of each company is calculated using the following formula:

(Average 2027 share price – Average 2024 share price + Dividends per share 2025-2027) / Average 2024 share price

Where:

– "Average 2027 share price" is the average of the opening share prices from January 1, 2027 through December 31, 2027;

– "Average 2024 share price" is the average of the opening share prices from January 1, 2024 through December 31, 2024;

and

– " Dividends per share 2025-2027" is the sum total of dividends paid out on the shares of each company from January 1,

2025 through December 31, 2027, without reinvestment .

The median TSR is the performance of the company ranked 7th within the peer panel.

At the end of the period, the difference between the Sanofi TSR and the median TSR is measured in percentage points, and

the Board of Directors will determine the TSR Allocation Rate as follows:

Difference in TSR performance ("D")	TSR Allocation Rate
If D is less than 0%	0%
If D is 0%	75%
If D is greater than 0% and less than +20%	75%+(Dx3.75)
If D is greater than or equal to +20%	150%

No TSR allocation may be made if Sanofi's TSR is lower than the median TSR.

• The CSR criterion accounts for 10% of the award. This performance condition equates to the attainment over a three-year

period of annual objectives plus a "stretch" objective, linked to the following pillars of Sanofi’s CSR strategy:

1. Affordable Access: providing essential medicines to non-communicable disease patients through Sanofi Global Health; and

2. Planet Care: Carbon Emissions Reduction, scopes 1 & 2 (reduction in emissions vs 2019).

Attainment of each annual CSR objective will earn one performance point; a maximum of three points, plus one extra point

linked to the "stretch" objective, can be earned for each CSR pillar. For each criterion, attainment of the objectives for 2027

will earn three points even if the annual objectives were not attained.

ITEM 6. Directors, Senior Management and Employees

At the end of the period, the Board of Directors will determine the CSR Allocation Rate corresponding to the number of points

earned, as shown below:

CSR points earned	CSR Allocation Rate
Less than 3 points	0%
3 points	50%
4 points	67%
5 points	83%
6 points	100%
7 points	110%
8 points	120%

• The R&D pipeline criterion, accounting for 10% of the award, was introduced in 2024 to reflect the importance of Sanofi's

commitment to developing a robust R&D pipeline. The performance criterion is based on the attainment levels of two equally-

weighted performance indicators measured over a three-year period.

1. Clinical Trial Readouts (CTRs) - the number of clinical trial results based on forecast pipeline deliveries

At the end of the period, the CTR attainment level will be calculated on the basis of the number of CTRs achieved in the period as

follows:

Number of Clinical Trial Readouts (CTRs)	CTR Attainment Level
CTR < 15	0%
CTR = 15	50%
CTR > 15, but < 30	(50+ [CTR – 15] x (10/3))%
CTR = 30	100%
CTR >30 but <35	(100+ [CTR– 30] x 4)%
CTR ≥ 35	120%

1. Regulatory Approvals (RAs) – the number of regulatory approvals obtained for new molecular entities (NMEs), new vaccine

entities (NVEs) or line extensions in key markets, relative to forecast pipeline deliveries

At the end of the period, the “Regulatory Approval” (RA) attainment level will be calculated on the basis of the number of RAs

vesting of the shares, net of the associated taxes and social contributions.

Each performance share awarded on April 30, 2025 was valued at €75.10, valuing the total benefit at €6,759,000.

The General Meeting of April 30, 2024 restricted the number of performance shares that can be awarded to executive officers

to 5% of the overall limit (itself set at 1.5% of the share capital). The number of shares awarded to Paul Hudson in 2025

Performance shares awarded to Paul Hudson which became available in 2025

(table No. 7 of the AFEP-MEDEF Code)

Paul Hudson was awarded 82,500 performance shares on May 3, 2022. The Board of Directors meeting of February 12, 2025

noted the level of attainment of the performance conditions applicable to this plan (84.36%), and 69,597 shares vested in Paul

Hudson on May 5, 2025.

Because awards of stock options to our Chief Executive Officer are not permitted under our compensation policy, tables No. 4

and No. 5 of the AFEP-MEDEF Code are not applicable.

Pension rights

Paul Hudson is entitled to benefits under the top-up defined-contribution pension plan introduced within Sanofi on

January 1, 2020. Under the terms of the plan, the Chief Executive Officer receives (subject to attainment of a performance

condition) an annual contribution of up to 25% of his reference compensation (annual fixed and variable compensation).

The performance condition for the vesting of pension rights is linked to the attainment of the performance criteria for 2025

variable compensation. The Board of Directors, at its meeting of February 11, 2026 , ascertained whether that performance

condition had been met, noting that the global attainment level for the variable portion of Paul Hudson’s compensation for the

2025 financial year was 109%.

The annual gross contribution is paid as follows:

• 50% as a gross insurance premium to the fund manager – the amount due to the fund manager with respect to 2025 is

€527,000; and

• 50% to Paul Hudson, to indemnify him for the social security and tax charges for which he will become immediately liable. The

amount due to Paul Hudson in respect of 2025 was set by the Board of Directors at its meeting of February 11, 2026

at €527,000.

Payment of those amounts is contingent on approval of the Chief Executive Officer’s compensation package by the shareholders

in an Ordinary General Meeting, on the terms stipulated in Article L. 22-10-34 II of the French Commercial Code.

(1) In 2025, it was agreed that for the purpose of calculating the attainment of quantitative criteria, the performance figures would be adjusted to eliminate

impacts related to (i) the acquisition of Blueprint and (ii) share buybacks; those adjustments negatively affected Sales Growth and Business EPS.

Social welfare and health insurance

Paul Hudson is subject to, benefits from and contributes to the same health cover, and death and disability plans, as are

applicable to other employees of Sanofi based in France. He also benefits from an unemployment insurance scheme.

Benefits in kind

The benefits in kind received by Paul Hu dson in 2025 were valued at €13,497 , and correspond to a company car with a driver.

Compensation and benefits for other Executive Committee members

Compensation

The compensation of Executive Committee members other than the Chief Executive Officer is reviewed by the Compensation

Committee, taking into consideration the practices of leading global pharmaceutical companies.

In addition to fixed compensation, they receive variable compensation. Their target variable compensation depends on their

position, and can represent up to 100% of their fixed compensation. The target amount of individual variable compensation is

determined in line with market practice. It rewards the joint contribution of all Executive Committee members to Sanofi’s

performance.

Fo r 2025 , the variable component consisted of three elements:

• attainment of quantitative objectives (accounting for 60%) measured at consolidated level: Sales growth 20%, Business EPS

20%, research and development outcomes 10%, and FCF 10%;

• attainment of (CSR) objectives measured at consolidated level (accounting for 10%); and

• attainment of individual quantitative and qualitative objectives (accounting for 30%).

The indicators (1) used are intended to measure Sanofi’s annual performance objectives; individual objectives; the attainment of

human capital objectives (such as gender representation in senior executive roles and transformation of the corporate culture to

align with Sanofi's strategy; and an objective relating to the reduction in Sanofi's carbon footprint.

In addition, Executive Committee members may be awarded performance shares.

For 2025 , the total gross compensation paid and accrued in respect of members of the Executive Committee (excluding the

Chief Executive Officer) was €20 million, of which €9 million was fixed compensation.

A total of 283,311 performance shares were awarded in 2025 to members of the Executive Committee (excluding the award to the

Chief Executive Officer). No stock options were awarded to members of the Executive Committee or the Chief Executive Officer

in 2025 .

In compliance with the AFEP-MEDEF Code, all awards are contingent upon five internal criteria: Business EPS, FCF, a CSR

criterion, and a criterion linked to the R&D pipeline. An external criterion based on TSR is also applied. Those criteria were

selected because they align equity-based compensation with the strategy adopted by Sanofi. The Board believes that the

performance conditions applied are good indicators of shareholder value creation in terms of the quality of investment decisions

and the commitment to deliver exacting financial results in a difficult economic environment.

The arrangements relating to these awards are as follows:

• The performance criterion based on Business EPS accounts for 35% of the award. Business EPS represents Sanofi's “business

net income” divided by the number of Sanofi shares; this criterion corresponds to the average actual-to-budget ratio of

Business EPS attained over the entire period. Budgeted business net income is derived from the budget as approved by the

Board of Directors at the beginning of each financial year. The Business EPS objective may not be lower than the bottom end

of the full-year guidance range publicly announced by Sanofi at the beginning of each year. If the ratio is less than 95% of the

objective, the corresponding performance shares are forfeited.

Business EPS actual-to-budget attainment level (B)	Business EPS allocation rate
If B is < 95%	0%
If B = 95%	50%
If B is > 95% but < 98%	(50 + [(B –95) x 16])%
If B is ≥ 98% but ≤ 105%	B%
If B is > 105% but < 110%	(105 + [(B –105) x 3])%
If B is ≥ 110%	120%

(2) Amgen Inc., AstraZeneca plc, Bayer AG, Bristol-Myers-Squibb Inc., Eli Lilly and Company Inc., GlaxoSmithKline plc, Johnson & Johnson Inc., Merck & Co.

Inc., Novartis AG, Novo Nordisk A/S, Pfizer Inc., and Roche Holding AG. The Board of Directors may review the composition of the panel during the

measurement period in exceptional circumstances (dissolution or merger of a panel company).

(3) Historical values are adjusted for spin-offs, stock splits/reverse stock splits, scrip dividends/bonus issues, rights issues, etc.

SANOFI FORM 20-F 2025 135

PART I
ITEM 6. Directors, Senior Management and Employees

• The FCF criterion accounts for 25% of the award. It represents the average actual-to-budget ratio of FCF attained over the

entire period. The award is based on a target FCF, below which some or all performance shares are forfeited.

FCF actual-to-budget attainment level (F)	FCF allocation rate
If F is ≤ 70%	0%
If F is > 70% but < 80%	[(F – 70) x 5]%
If F = 80%	50%
If F is > 80% but < 100%	(50 + [(F – 80) x 2.5])%
If F = 100%	100%
If F is > 100% but < 120%	F%
If F is > 120%	120%

• The criterion based on TSR Rank Improvement accounts for 20% of the award.

• This performance criterion compares Sanofi's three-year TSR performance with the median TSR of comparable companies

included in a peer panel of 12 pharmaceutical companies (2) over the same period. Sanofi's TSR corresponds to the performance

of the Sanofi share price (3) uplifted by dividends per share during the measurement periods, without reinvestment.

TSR calculation

The TSR of each company is calculated using the following formula:

(Average 2027 share price – Average 2024 share price + Dividends per share 2025-2027) / Average 2024 share price

Where:

– "Average 2027 share price" is the average of the opening share prices from January 1, 2027 through December 31, 2027;

– "Average 2024 share price" is the average of the opening share prices from January 1, 2024 through December 31, 2024;

and

– " Dividends per share 2025-2027" is the sum total of dividends paid out on the shares of each company from January 1,

2025 through December 31, 2027, without reinvestment .

• The criterion based on CSR accounts for 10% of the award, and is linked to attainment of (i) annual objectives over a

three-year period and (ii) a "stretch" objective, linked to the following pillars:

1. Affordable Access: providing essential medicines to non-communicable disease patients through Sanofi Global Health; and

2. Planet Care: Carbon Emissions Reduction, scopes 1 & 2 (reduction in emissions vs 2019).

Attainment of each annual CSR objective will generate one performance point; a maximum of three points (plus one bonus

point for the "stretch" objective) may be obtained for each pillar. For each criterion, attainment of the 2026 objectives will

generate three points, even if the annual objectives are not attained.

• The R&D pipeline criterion, accounting for 10% of the award, corresponds to the attainment levels of two equally-weighted

performance indicators measured over a three-year period:

1. CTRs - the number of clinical trial results based on forecast pipeline deliveries;

2. Regulatory Approvals – the number of regulatory approvals obtained for NMEs, NVEs or line extensions in key markets,

relative to forecast pipeline deliveries.

• The number of performance shares vesting depends on the overall allocation rate, which for each period is the weighted

average of the Business EPS allocation rate (35%), the FCF allocation rate (25%), the TSR allocation rate for the period (20%),

the CSR allocation rate (10%), and the R&D allocation rate (10%).

• In order to align equity-based compensation with medium-term performance, performance is measured over three financial years.

• Vesting is subject to a non-compete clause.

• The entire award is forfeited in the event of resignation, or dismissal for gross or serious misconduct;

• In the event of (i) individual dismissal other than for gross or serious misconduct, (ii) retirement before the age of 60, (iii) the

beneficiary’s employer ceasing to be part of the Sanofi group or (iv) termination of employment contract under the terms of a

collective separation plan initiated by the employer in accordance with locally applicable legislation or measures approved by

local authorities, the overall allocation percentage is apportioned on a pro rata time basis to reflect the amount of time the

person remained with the Sanofi group during the vesting period.

• If any of the following events occur, full rights to the award are retained: (i) retirement on or after reaching the statutory

retirement age, or after the age of 60 under any circumstances;; (ii) disability classified in the second or third categories as

stipulated in Article L. 314-4 of the French Social Security Code; or (iii) death of the beneficiary.

Pension arrangements

The total amount accrued as of December 31, 2025 in respect of corporate pension plans for persons who have held an executive

position during 2025 was € 10 million. That amount includes an expense of €1 million recognized in profit or loss during 2025 .

Pay ratio between compensation of executive officers and average/median compensation of Sanofi

employees – changes in compensation of executive officers and employees relative to the performance

of Sanofi

This information is disclosed in accordance with Article L. 22-10-9 6° of the French Commercial Code, further to the enactment

of the “Pacte” law.

Sanofi has referred to the guidance on compensation multiples issued by AFEP (version issued February 2021) in establishing the

calculation methods used for the ratios presented.

Explanations of calculation methods and of year-on-year changes in the executive pay ratio:

• the scope includes Sanofi SA (the parent company) and all of its direct and indirect subsidiaries located in France, and hence

covers more than 80% of total payroll of permanent employees in France. Opella group employees are no longer included

within the scope from 2025. No separate ratios are published for Sanofi SA (the parent company), as the low headcount at

Sanofi SA means that such ratios would not be representative of our total headcount in France;

• the employee compensation used in the calculation is the full time equivalent (FTE) compensation of permanent employees

with at least two financial years of uninterrupted employment;

• direct compensation includes fixed compensation awarded during the reference year, and variable compensation related to

the previous year and paid during the reference year. All compensation amounts are gross amounts;

• in order to maintain consistency, we have excluded from the numerator (i) compensation items not included in the denominator

and (ii) non-recurring compensation items. This applies in particular to accommodation expenses related to the relocation to

France of the Chief Executive Officer (Paul Hudson) in 2020, and to expenses related to unemployment insurance;

• long term variable compensation: performance shares and stock options awarded during each reference year are valued at

the date of grant in accordance with International Financial Reporting Standards. The valuation of performance shares that

include the Total Shareholder Return (TSR) performance condition incorporates market conditions where applicable. Awards

are subject to a continuing employment condition (three years minimum) and to performance conditions. Consequently, the

valuation at the date of grant is not necessarily indicative of the value of stock options and performance shares at the end of

the vesting period, especially if the performance conditions are not met;

• since Olivier Brandicourt (our previous Chief Executive Officer) received the same number of stock options and performance

shares each year from 2016 to 2019, fluctuations in the Sanofi share price had a significant impact on the pay ratio during this

period;

• 2018 and 2019 figures have been restated for comparative purposes, to (i) exclude Sanofi’s equity-accounted share of

Regeneron’s net profits (see Note D.1. to our consolidated financial statements included at Item 18. of this annual report) and

(ii) include the effects of IFRS 16;

• regular benchmarking reviews are conducted to ensure that the level of compensation awarded to our employees and CEO is

competitive and consistent with pharmaceutical industry levels.

C. Board Practices

Application of the AFEP-MEDEF Code

The corporate governance code applied by Sanofi is the December 2022 version of the AFEP-MEDEF Code which is available at

https://hcge.fr/le-code-afep-medef/.

Our Board Charter requires at least one-half of our directors to be independent; contains a section on the ethical rules applicable

to our directors; sets out the remit and operating procedures of the Board; defines the roles and powers of our Chairman and our

Chief Executive Officer; and describes the composition, remit and operating procedures of the Board committees, in accordance

with the recommendations of the AFEP-MEDEF Code. Collectively, our Articles of Association and our Board Charter establish

the framework within which Sanofi implements its principles of corporate governance

Our Board practices comply with the AFEP-MEDEF Code recommendations, with certain exceptions, and with the report of the

Autorité de marchés financiers on Audit Committees, issued on July 22, 2010.

Activities of the Board of Directors in 2025

During 2025 , the Board of Directors met fourteen times (including strategy seminars) , with an overall attendance rate among

Board members of 99% .

The following persons attended meetings of the Board of Directors:

• the directors;

• the Secretary to the Board;

• frequently: members of the Executive Committee; and

• occasionally: the statutory auditors, managers of our global support functions, and other company employees.

The agenda for each meeting of the Board is prepared by the Secretary after consultation with the Chairman, taking account of

the agendas for the meetings of the specialist Committees and the suggestions of the directors.

Approximately one week prior to each meeting of the Board of Directors, the directors each receive a file containing the agenda,

the minutes of the previous meeting, and documentation relating to the agenda.

The minutes of each meeting are expressly approved at the next meeting of the Board of Directors.

In compliance with our Board Charter, certain issues are examined in advance by the various Committees according to their areas

of competence, to enable them to make a recommendation; those issues are then submitted for a decision by the Board of

Directors.

Since 2016, acting on a recommendation from the Appointments, Governance and CSR Committee, each year the Board has held

at least two executive sessions, i.e. meetings held without the Chief Executive Officer present. If the Chairman of the Board so

decides, such sessions may also be held without the directors representing employees (or any other Sanofi employee) being

present. The primary purpose of such sessions is to evaluate the way the Board and its Committees operate, discuss the

performance of the Chief Executive Officer, and debate succession planning. Three executive sessions were held in 2025 : two

one-hour sessions in January and February, and a 20-minute session in April.

In addit ion, two strategy seminars were held, in April and October 2025 , in which members of the Executive Committee took part.

The seminar gave directors an opportunity to address issues including:

• strategic aspects of acquisitions: future prospects and feedback;

• impacts and changes driven by artificial intelligence across the value chain;

• global pricing strategy for medicines and vaccines;

• governance of R&D activities;

• update on the product portfolio;

• medium/long-term financial trajectory, including forecasts arising from "Strat Days" (two-day Executive Committee meetings

• review of commercial performances in France;

• capital allocation strategy in terms of commercial development and mergers/acquisitions;

• transformation of the R&D function: governance, human resources and key performance indicators;

• status report on Manufacturing & Supply, with specific focus on operations in France; and

• monitoring of Sanofi's ranking and reputation.

Finally, a site visit to the facility at Vitry-sur-Seine in France gave Board members an opportunity to see how Sanofi's R&D and

Remit and Operation of Board Committees

Our Board of Directors is assisted in its deliberations and decisions by five specialist Committees (for a description of the remit of

each Committee, refer to our Board Charter, provided as Exhibit 1.2 to this annual report). Chairs and members of these

Committees are chosen by the Board from among its members, based on their experience.

The Committees are responsible for the preparation of certain items on the agenda of the Board of Directors. Decisions of the

Committees are adopted by a simple majority with the Chair of the Committee having a casting vote. Minutes are prepared, and

approved by the Committee members.

The Chair of each Committee reports to the Board on the work of that Committee, so that the Board is fully informed whenever it

takes a decision.

Industrial Relations

In all countries where we operate, we seek to strike a balance between our economic interests and those of our employees, which

we regard as inseparable.

Our belief in a balanced workplace for our employees is based on the basic principles of our Social Charter, which outlines the

rights and duties of all Sanofi employees. The Social Charter addresses our key ambitions vis-à-vis our workforce: equal

opportunity for all people without discrimination, the right to health and safety, respect for privacy, the right to information and

professional training, social protection for employees and their families, freedom of association and the right to collective

bargaining, and respect for the principles contained in the Global Compact on labor relations and ILO conventions governing the

physical and emotional well-being and safety of children.

Our labor relations are based on respect and dialogue. In this spirit, management and employee representatives meet regularly to

exchange views, negotiate, sign agreements and ensure that agreements are being implemented.

Employee dialogue takes place in different ways from country to country, as dictated by specific local circumstances. Depending

on the circumstances, employee dialogue relating to information, consultation and negotiation processes may take place at

national, regional or company level. It may be organized on an interprofessional or sectorial basis, or both. Employee dialogue

may be informal or implemented through a specific formal body, or a combination of both methods. Whatever the situation,

Sanofi encourages employees to voice their opinions, help create a stimulating work environment and take part in decisions

aiming to improve the way we work. These efforts reflect one of the principles of the Social Charter, whereby improving working

conditions and the necessary adaptation to our business environment go hand-in-hand.

ITEM 6. Directors, Senior Management and Employees

Profit-sharing Schemes, Employee Savings Schemes and Employee Share Ownership

Profit-sharing schemes

All employees of our French companies belong to voluntary and statutory profit-sharing schemes.

Voluntary schemes

Voluntary schemes (intéressement des salariés) are collective schemes that are optional for the employer and contingent upon

pe rformance. The aim is to give employees an interest in the growth of the business and improvements in its performance.

In June 2023, we entered into a new fixed-term statutory profit-sharing agreement for the 2023, 2024 and 2025 financial years,

which applies to all employees of our French companies. Under the agreement, Sanofi pays collective variable compensation

determined on the basis of the more favorable of (i) growth in consolidated net sales (at constant exchange rates and on a

constant structure basis) or (ii) the ratio of business operating income to net sales on a reported basis (BOI margin). For each of

those criteria, a matrix determines what percentage of total payroll is to be allocated to the scheme. An additional sum capped at

0.5% of total payroll may also be distributed, determined on the basis of two CSR-related performance conditions, each

weighted at 0.25%:

• a criterion reflecting progress in environmental matters (reduction in Sanofi greenhouse gas emissions worldwide); and

• a social responsibility criterion: the number of employees in France registered on Sanofi-referenced volunteering programs.

This overall allocation is reduced by the amount required by law to be transferred to a special profit-sharing reserve. The balance

is then distributed between the employees unless the transfer to the reserve equals or exceeds the maximum amount determined

under the specified criteria, in which case no profit share is paid to the employees.

No distribution was made under the voluntary scheme in 2025 in respect of 2024 .

Statutory scheme

The statutory scheme (participation des salariés aux résultats de l’entreprise) is a French legal obligation for companies with

more than 50 employees that made a profit in the previous financial year.

The amo unt distributed by our French companies in 2025 in respect of the statutory scheme for the year ended

December 31, 2024 represented 8.29% of total payroll.

Distribution formula

In order to favor lower-paid employees, the voluntary and statutory profit-sharing agreements entered into since 2005 split the

benefit between those entitled as follows:

• 60% prorated on the basis of time spent in the Company’s employment in the year; and

• 40% prorated on the basis of gross annual salary received during the year, subject to a lower limit equal to the social security

ceiling and an upper limit of three times the social security ceiling.

Employee savings schemes and collective retirement savings plan

The employee savings arrangements operated by Sanofi are based on a collective savings scheme (Plan d’Épargne Groupe) and a

collective retirement savings scheme (Plan d’Épargne pour la Retraite Collectif) . Those schemes reinvest the sums derived from

the statutory and voluntary profit-sharing schemes, plus voluntary contributions from employees.

In June 2025 , 92% o f the employees who benefited from the profit-sharing schemes opted to invest in the collective savings

scheme, and nea rly 75.3% opted to invest in the collective retirement savings scheme.

Sanofi supplements the amount invested by employees in these schemes by making a top-up contribution.

In 2025 , €160 mill ion was invested in the collective savings scheme and €61.3 m illion in the collective retirement savings scheme,

through the voluntary and statutory schemes and through top-up contributions.

Employee share ownership

As of December 31, 2025 , shares held under the collective savings scheme or in registered form by employees of Sanofi,

employees of related companies and former employees amoun te d to 2.93% of our share capital.

For more information about our most recent employee share ownership plan, refer to “Item 10. Additional Information — Changes

in Share Capital — Increases in Share Capital”.

In 2019, the Board of Directors reviewed Sanofi’s compensation policy and decided that stock options would no longer be

awarded from 2020 onwards. That decision was taken to standardize the terms of equity-based compensation awards within

Sanofi, and in response to feedback from some shareholders and proxy advisors who had concerns about stock options given

their dilutive effect and potential unintended consequences.

725,044 options were immediately exercisable.

Existing Performance Share Plans as of December 31, 2025

The Board of Directors awards shares to certain employees in order to give them a direct stake in our future and performances

via trends in the share price, as a partial substitute for the granting of stock options.

Shares are awarded to employees by the Board of Directors on the basis of a list submitted to the Compensation Committee. The

Board of Directors sets terms of the awards, including continuing employment conditions and performance conditions (measured

over three financial years).

The employee plans have a three-year vesting period, with no lock-up period.

• At its meeting of April 30, 2025 , the Board of Directors awarded a share performance plan, cascaded down into three sub-plans:

– a plan under which 463 beneficiaries classified as “Senior Executives” were awarded a total of 1,331,892 shares;

– a plan under which 7,700 beneficiaries not classified as “Senior Executives” were awarded a total of 2,599,478 shares;

– a plan under which 90,000 performance shares were awarded to the Chief Executive Officer.

Of the 8,164 beneficiaries, 51% were women.

• At its meeting of October 23, 2025, the Board of Directors awarded a share performance plan, cascaded down into

two sub-plans:

– a plan under which 25 beneficiaries classified as “Senior Executives” were awarded a total of 107,291 performance shares;

– a plan under which 6 beneficiaries not classified as “Senior Executives” were awarded a total of 7,833 performance shares.

Of those 31 beneficiaries, 45% were women.

148 SANOFI FORM 20-F 2025

PART I
ITEM 6. Directors, Senior Management and Employees

The entirety of those awards is contingent upon criteria based on business net income (BNI), free cash flow (FCF) and Corporate

Social Responsibility (CSR); in the case of employees classified as “Senior Executives”, two additional criteria based on (i) total

shareholder return (TSR) and (ii) the R&D allocation rate were added, accounting for respectively 20% and 10% of the total.

Vesting is subject to a non-compete clause.

The number of shares awarded to the Chief Executive Officer in 2025 represents 0.5% of the total limit approved by our

shareholders at the Annual General Meeting of April 30, 2025 (1.5% of our share capital) and 2.22% of the total amount awarded

to all beneficiaries in 2025 .

The 2025 awards represent a dilution of approximately 0.21% of our undiluted share capital as of December 31, 2025 .

Not all of our employees were awarded performance shares, but a new voluntary profit-sharing agreement was signed in June

2023 , which gives all of our employees an interest in Sanofi’s performance (for more details refer to “— Profit-Sharing Schemes,

Employee Savings Schemes and Employee Share Ownership” above).

(a) BlackRock, Inc. reported ownership of 72,127,649 ordinary shares on a Schedule 13G filed on April 23, 2025 (reported as representing 5.8% of Sanofi’s

share capital in the Schedule 13G). The amounts reported in the table are based on an ownership declaration from BlackRock, Inc. dated July 31, 2025

and provided pursuant to disclosure obligations related to crossing share ownership thresholds specified in Sanofi’s Articles of Association ("statuts").

(b) Shares held by the employees according to article L. 225-102 of the French Commercial Code as of December 31, 2025. Amundi (together with Amundi

Asset Management) filed a Schedule 13G on November 14, 2025 reporting ownership of 63,898,970 shares (reported as representing 5.21% of Sanofi’s

share capital in Schedule 13G), including 28,440,459 shares over which Amundi does not have voting rights, which are held through FCPEs (Fonds

Commun de Placement d'Entreprise, an investment vehicle established under French law) solely dedicated to Sanofi group employee share ownership,

the voting rights of which are exercised by the holders of FCPE units and/or the supervisory board of the FCPEs. Amundi stated that the voting rights

associated with these shares are exercised by the Supervisory Boards of the FCPEs and not by Amundi.

(c) Number of shares repurchased as of January 31, 2026 under the share repurchase programs approved by our shareholders from time to time.

(d) Based on the total number of voting rights as of January 31, 2026 .

(e) Based on the total number of voting rights as of January 31, 2026 as published in accordance with Article 223-11 et seq. of the General Regulations of

the Autorité des marchés financiers (i.e. including treasury shares, the voting rights of which are suspended).

Our Articles of Association provide for double voting rights for shares held in registered form (i.e. where the ultimate shareholder’s

identity is recorded in our share register) for at least two years. All of our shareholders may benefit from double voting rights if

these conditions are met, and no shareholder benefits from specific voting rights. For more information relating to our shares, see

“Item 10. Additional Information — B. Memorandum and Articles of Association.”

Neither L’Oréal nor BlackRock holds different voting rights from those of our other shareholders.

To the best of our knowledge, no other shareholder currently holds, directly or indirectly and acting alone or in concert, more

than 5% of our share capital or voting rights. Furthermore, we believe that we are not directly or indirectly owned or controlled by

another corporation or government, or by any other natural or legal persons. To our knowledge, there are no arrangements that

may result in a change of control.

During the year ended December 31, 2025 we received one share ownership declaration from L'Oréal informing us that a legal

threshold had been passed, as required under Article L. 233-7 of the French Commercial Code. L'Oréal’s declaration stated that

on February 5, 2025 its ownership of Sanofi voting rights passed below the 15% legal threshold to 12.73% and that its current

ownership of share capital was 7.02%.

In addition to the statutory requirement to inform the Company and the Autorité des marchés financiers (AMF, the French

Financial Markets Regulator) that they hold a number of shares (or of securities equivalent to shares or of voting rights

pursuant to Article L. 233-9 of the French Commercial Code) representing more than one-twentieth (5%), one-tenth (10%),

three-twentieths (15%), one-fifth (20%), one-quarter (25%), three-tenths (30%), one-third (1/3), one-half (50%), two-thirds (2/3),

nine-tenths (90%) or nineteen-twentieths (95%) of the share capital or theoretical voting rights within four trading days after

crossing any such ownership threshold (Article L. 233-7 of the French Commercial Code), any natural or legal person who directly

or indirectly comes to hold a percentage of the share capital, voting rights or securities giving future access to the Company’s

capital that is equal to or greater than 1% or any multiple of that percentage, is obliged to inform the Company thereof by

registered mail, return receipt requested, indicating the number of securities held, within five trading days following the date on

which each of the thresholds was crossed.

If such declaration is not made, the shares in excess of the fraction that should have been declared will be stripped of voting

rights at shareholders’ meetings, if on the occasion of such meeting, the failure to declare has been formally noted and one or

more shareholders collectively holding at least 5% of the Company’s share capital or voting rights so request at that meeting.

Any natural or legal person is also required to inform the Company, in the forms and within the time limits stipulated above for

passing above a specified threshold, if their direct or indirect holding passes below any of the aforementioned thresholds.

Since January 1, 2026, Sanofi has only received share ownership declarations as required under Sanofi's Articles of Association .

Our consolidated financial statements as of and for the years ended December 31, 2025 , 2024 and 2023 are included of this

annual report at “Item 18. Financial Statements.”

Dividends on ordinary shares

We paid annual dividends for the years ended December 31, 2021 , 2022 , 2023 and 2024 and our shareholders will be asked to

approve the payment of an annual dividend of € 4.12 per share for the 2025 fiscal year at our next annual shareholders’ meeting. If

approved, this dividend will be paid on May 7, 2026.

We expect that we will continue to pay regular dividends based on our financial condition and results of operations. The

proposed 2025 dividend equates to a distribution of 55.0 % of our business net income. For information on the non-IFRS financial

measure “business earnings per share” see “Item 5. Operating and Financial Review and Prospects — Business Net Income.”

The following table sets forth information with respect to the dividends paid by our Company in respect of the 2021 , 2022 , 2023

and 2024 fiscal years and the dividend that will be proposed for approval by our shareholders in respect of the 2025 fiscal year at

our April 29, 2026 shareholders’ meeting.

(a) Proposal, subject to shareholder approval.

(b) Plus a dividend in kind of EUROAPI shares, at a ratio of one EUROAPI share per 23 Sanofi shares.

The declaration, amount and payment of any future dividends will be determined by majority vote of the holders of our shares at

an ordinary general meeting, following the recommendation of our Board of Directors. Any declaration will depend on our results

of operations, financial condition, cash requirements, future prospects and other factors deemed relevant by our shareholders.

Accordingly, we cannot assure you that we will pay dividends in the future on a continuous and regular basis. Under French law,

we are required to pay dividends approved by an ordinary general meeting of shareholders within nine months following the

meeting at which they are approved.

Disclosure pursuant to Section 13(r) of the United States Exchange Act of 1934

Sanofi engages in limited business activities with Iran related to human health products – namely, sales of bulk and branded

pharmaceuticals and vaccines. These activities, which are disclosed pursuant to Section 13(r) of the United States Exchange Act

of 1934, as amended, are not financially material to Sanofi and contributed well under 1% of Sanofi’s consolidated net sales

in 2025 .

Sanofi’s US affiliates and non-US affiliates owned or controlled by Sanofi’s US affiliates either do not engage in Iran-related

activities or act under licenses issued by the US Department of the Treasury’s Office of Foreign Assets Control (OFAC).

Sanofi and certain non-US Sanofi affiliates engage in limited business activities that neither are expressly authorized by OFAC nor

require such authorization.

In 2016, Sanofi and the Iran Food and Drug Administration (IFDA), an entity affiliated with the Iranian Ministry of Health and

Medical Education, signed a Memorandum of Cooperation (MOC) regarding: (i) potential future projects to reinforce current

partnerships with reputable Iranian manufacturers (in particular, to enhance industrial quality standards); (ii) collaborating with

the Ministry of Health and Medical Education on programs for the prevention and control of certain chronic and

non-communicable diseases (in particular, diabetes); and (iii) potential future collaboration on epidemiological studies. In 2025 ,

activities conducted under the MOC did not generate any revenue or net profits.

Certain non-US Sanofi affiliates engage in limited business with Iranian counterparties associated with the Iranian Ministry of

Health, such as public hospitals or distributors. In 2025 , those business activities generated approximately €28.4 million in gross

revenue and contributed no more than €6.5 million in net profit.

Finally, a representative office in Tehran currently under liquidation incurs incidental expenses from state-owned utilities.

Sanofi believes that it and its affiliates’ activities are compliant with applicable law, and in light of the nature of the activities

concerned, Sanofi and its affiliates intend to continue their ongoing activities in Iran.

ITEM 8. Financial Information

Information on Legal or Arbitration Proceedings

This Item 8. incorporates by reference the disclosures found in Note D.22. to the consolidated financial statements at

Item 18. of this annual report; material updates thereto as of the date of this annual report are found below under the

heading “— B. Significant Changes — Updates to Note D.22.”.

Sanofi and its subsidiaries are involved in litigation, arbitration and other legal proceedings. These proceedings typically are

related to product liability claims, intellectual property rights (particularly claims against generic companies seeking to limit the

patent protection of Sanofi products), competition law and trade practices, commercial claims, employment and wrongful

discharge claims, tax assessment claims, waste disposal and pollution claims, and claims under warranties or indemnification

arrangements relating to business divestitures. As a result, we may become subject to substantial liabilities that may not be

covered by insurance and could affect our business and reputation. While we do not currently believe that any of these legal

proceedings will have a material adverse effect on our financial position, litigation is inherently unpredictable. As a

consequence, we may in the future incur judgments or enter into settlements of claims that could have a material adverse

effect on results of operations, cash flows and/or our reputation.

Government Investigations and Related Litigation

From time to time, subsidiaries of Sanofi are subject to governmental investigations and information requests from regulatory

authorities inquiring as to the practices of Sanofi with respect to the sales, marketing, and promotion of its products. Sanofi US

has been subject to a number of government investigations and legal actions in the United States related to the pricing of

Sanofi’s insulin products (including Sanofi’s pricing practices for Lantus, Toujeo and/or Soliqua). The insulin-pricing litigation has

been consolidated in Multi-District Litigation (MDL) in New Jersey Federal Court, and includes claims by state attorneys general,

self-funded payors, and other plaintiffs. Sanofi has resolved some cases through settlement or dismissal and has also secured the

dismissal of some claims in the MDL; other claims are proceeding into discovery. Sanofi subsidiaries are also defending (i) an

insulin-related antitrust suit brought on behalf of direct purchasers in Massachusetts Federal Court, where a final decision on

summary judgment could come by the end of March 2026; and (ii) an antitrust suit brought by Mylan (relating to Mylan’s insulin

product, Semglee) in the Federal Court in the Western District of Pennsylvania.

In September 2019, Sanofi US received a Civil Investigative Demand (CID) from the US Department of Justice (DOJ)

concerning Dupixent, Kevzara, Praluent and Zaltrap, and Sanofi is defending the related non-intervened False Claims Act lawsuit

currently on appeal before the Ninth Circuit Court of Appeals following dismissal at the district court level.

In May 2025, Sanofi US received a subpoena from the US Department of Health and Human Services Office of Inspector General

(HHS-OIG) in Philadelphia seeking information on agreements with pharmacy benefit managers (PBMs) and group purchasing

organizations (GPOs), including drug utilization data from 2020 to the present, as part of a joint investigation with the US

Department of Justice (DOJ) and the US Attorney’s Office for the Eastern District of Pennsylvania; Sanofi is cooperating.

In March 2025, Sanofi US received a Civil Investigative Demand (CID) from the US Department of Justice (DOJ) under the False

Claims Act requesting information on Beyfortus, an RSV (Respiratory Syncytial Virus) vaccine co-developed and commercialized

with a partner, referencing a May 2024 FDA inspection of a North Carolina manufacturing facility; Sanofi is cooperating.

In February 2024, Sanofi US was served with a qui tam complaint in Texas state court alleging violations of the Texas Medicaid

Fraud Prevention Act (TMFPA). The complaint alleges that the Company engaged outside vendors to provide nursing and

reimbursement services related to certain insulin products in violation of the TMFPA. In October 2025, the relator filed an

amended petition expanding the allegations to include seven additional products: Altuviiio, Aubagio, Cerdelga, Nexviazyme,

Dupixent, Rezurock, and Tzield. In January 2026, the State of Texas intervened in the case. Discovery is ongoing, with trial

scheduled for July 2027.

(1) The appointment of Belén Garijo as a director, as well as the amendment of the articles of association to raise the age limit of the Chief Executive Officer

upon appointment, necessary for this election, will be proposed to the vote of the shareholders at the General Meeting of April 29, 2026.

Other Changes

On January 29, 2026, Sanofi announced its intention to execute a share buyback program in 2026 of €1 billion. On February 2,

2026, Sanofi entered a mandate with an investment service provider for this program. Under the terms of the mandate, Sanofi

will repurchase its own shares for a total consideration of up to €1 billion, between February 3, 2026 and December 31, 2026, at

the latest.

On February 10, 2026, Sanofi announced that it had completed the acquisition of Dynavax Technologies Corporation (Dynavax).

The acquisition includes Dynavax’s adult hepatitis B vaccine HEPLISAV-B, which is currently marketed in the US and is

differentiated by its two-dose regimen over one month. It also includes Dynavax’s shingles vaccine candidate (Z-1018), whi ch is

currently in phase 1/2 studies, and additional vaccine pipeline projects.

On February 12, 2026, Sanofi announced that Sanofi's Board of Directors met on February 11, 2026, and decided not to renew the

Director mandate of Paul Hudson. As a result, Paul Hudson’s last day as Chief Executive Officer will be on February 17, 2026 at the

end of business. The Board thanks him for his valuable contributions to the transformation and development of the Group over

the last six years. Following the proposal of the Appointments, Governance and CSR Committee , the Board of Directors

appointed Belén Garijo as Chief Executive Officer. She will take up her duties after the Group's Annual General Meeting on

April 29, 2026. The Board will also propose to the shareholder vote the candidacy of Belén Garijo as a director of the Group (1) .

Olivier Charmeil, Executive Vice President, General Medicines, and member of the Executive Committee since 2011, will assume

the role of Interim Chief Executive Officer during this transition.

On February 16, 2026, Sanofi announced that a universal respiratory syncytial virus (RSV) immunization program using Beyfortus

(nirsevimab) was associated with a statistically significant reduction in RSV-related hospitalizations in the second RSV season

among infants immunized during their first season, according to a new study published in The Lancet Infectious Diseases. The

NIRSE-GAL study, conducted in Galicia, Spain, is the first prospective real-world population study to evaluate the impact of a

universal Beyfortus immunization program during two consecutive RSV seasons. The study findings, comparing the number of

hospitalizations in immunized infants during their second RSV season versus the number of expected hospitalization cases based

on data from recent seasons, are being presented at RSVVW ’26 (Respiratory Syncytial Virus Vaccines for the World) conference

in Rome, Italy.

On February 17, 2026, Sanofi announced the nomination of Manuela Buxo as Executive Vice-President, Specialty Care, effective

March 1, 2026. Manuela will succeed Brian Foard, who has decided to leave the company as of February 28, 2026, having

accepted an external leadership opportunity.

B. Memorandum and Articles of Association

General

Our Company is a société anonyme , a form of limited liability company, organized under the laws of France. The LEI number of

the Company is 549300E9PC51EN656011.

In this section, we summarize material information concerning our share capital, together with material provisions of applicable

French law and our Articles of Association (statuts) , an English translation of which has been filed as an exhibit to this annual

report. For a description of certain provisions of our Articles of Association relating to our Board of Directors and statutory

auditors, see “Item 6. Directors, Senior Management and Employees." You may obtain copies of our Articles of Association in

French from the greffe (Clerk) of the Registre du Commerce et des Sociétés de Paris (Registry of Commerce and Companies of

Paris, France, registration number: 395 030 844). Please refer to that full document for additional details.

Our Articles of Association specify that our corporate affairs are governed by:

• applicable laws and regulations (in particular, Title II of the French Commercial Code); and

• the Articles of Association themselves.

Article 3 of our Articles of Association specifies that the Company’s corporate purpose, in France and abroad, is:

• acquiring interests and holdings, in any form whatsoever, in any company or enterprise, in existence or to be created,

connected directly or indirectly with the health and fine chemistry sectors, human and animal therapeutics, nutrition and

bio-industry:

– in the following areas:

• purchase and sale of all raw materials and products necessary for these activities,

• research, study and development of new products, techniques and processes,

• manufacture and sale of all chemical, biological, dietary and hygienic products,

• obtaining or acquiring all intellectual property rights related to results obtained and, in particular, filing all patents,

trademarks and models, processes or inventions,

• operating directly or indirectly, purchasing, and transferring – for free or for consideration – pledging or securing all

intellectual property rights, particularly all patents, trademarks and models, processes or inventions,

• obtaining, operating, holding and granting all licenses,

• within the framework of a group-wide policy and subject to compliance with the relevant legislation, participating in

treasury management transactions, whether as lead company or otherwise, in the form of centralized currency risk

management or intra-group netting, or any other form permitted under the relevant laws and regulations,

• acquiring any real estate assets in connection with the corporate purpose, or selling real estate assets owned by the company;

– and, more generally:

• all commercial, industrial, real or personal property, financial or other transactions, connected directly or indirectly,

totally or partially, with the activities described above and with all similar or related activities and even with any other

purposes likely to encourage or develop the Company’s activities.

Directors

Transactions in which directors are materially interested

Under French law, any agreement entered into (directly or through an intermediary) between our Company and any one of the

members of the Board of Directors that is not entered into (i) in the ordinary course of our business and (ii) under normal

conditions, is subject to the prior authorization of the disinterested members of the Board of Directors. The same provision

applies to agreements between our Company and another company if one of the members of the Board of Directors is the

owner, general partner, manager, director, general manager or member of the executive or supervisory board of the other

company, as well as to agreements in which one of the members of the Board of Directors has an indirect interest.

SANOFI FORM 20-F 2025 157

PART I
ITEM 10. Additional Information

The Board of Directors must also approve any undertaking taken by our Company for the benefit of our Chairman, Chief

Executive Officer (directeur général) or his delegates (directeurs généraux délégués) pursuant to which such persons will or may

be granted compensation, benefits or any other advantages as a result of the termination of or a change in their offices or

following such termination or change, in accordance with Article L. 22-10-8 III of the French Commercial Code. Each such

undertaking must be included in our compensation policy for corporate officers, which is submitted for approval by our

shareholders at the Annual General Meeting in accordance with Article L. 22-10-8 II of the French Commercial Code. No such

compensation or undertaking may be determined, awarded or paid unless in accordance with such compensation policy.

See “Item 6. Directors, Senior Management and Employees — B. Compensation” for a description of the process for establishing

and authorizing such compensation policy.

Directors’ compensation

The aggregate amount of compensation of the Board of Directors is determined at the Shareholders’ Ordinary General Meeting.

The Board of Directors then divides this aggregate amount among its members by a simple majority vote. In addition, the Board

of Directors may grant exceptional compensation (rémunérations exceptionnelles) to individual directors on a case-by-case basis

for special assignments following the procedures described above at “— Transactions in which directors are materially

interested”. The Board of Directors may also authorize the reimbursement of travel and accommodation expenses, as well as

other expenses incurred by Directors in the corporate interest. See also “Item 6. Directors, Senior Management and Employees.”

Furthermore, under our Articles of Association, the Board of Directors may compensate any observers (censeurs) to the Board of

Directors, which would reduce by the same amount the total annual compensation available for allocation to the Board of

Directors.

Board of Directors’ authority to take out loans or borrow money on behalf of the Company

All loans or borrowings on behalf of the Company may be decided by the Board of Directors within the limits, if any, imposed by

the Shareholders’ Extraordinary General Meeting. There are currently no limits imposed on the amounts of loans or borrowings

that the Board of Directors may approve.

Directors’ age limits

For a description of the provisions of our Articles of Association relating to age limits applicable to our Directors, see

“Item 6. Directors, Senior Management and Employees – A. Directors and Senior Management."

Directors’ share ownership requirements

Pursuant to our Articles of Association, each director appointed by a Shareholders’ Ordinary General Meeting must own at

least 500 shares throughout their term of office. In addition, pursuant to the Board Charter (an English language version of which

is reproduced in full as Exhibit 1.2 to this annual report), our Directors must within no more than two years from their appointment

hold at least 1,000 Sanofi shares in their own name, which must be retained until they cease to hold office.

Shareholders’ meetings

General

In accordance with the provisions of the French Commercial Code, there are three types of shareholders’ meetings: ordinary,

extraordinary and special.

Ordinary general meetings of shareholders are required for matters such as:

• electing, replacing and removing Directors;

• appointing independent auditors;

• approving the annual financial statements;

• declaring dividends or authorizing dividends to be paid in shares, provided the Articles of Association contain a provision to

that effect; and

• approving share repurchase programs.

Extraordinary general meetings of shareholders are required for approval of matters such as amendments to our Articles of

Association, including any amendment required in connection with extraordinary corporate actions. Extraordinary corporate

actions include:

• changing our Company’s name or corporate purpose;

• increasing or decreasing our share capital;

• creating a new class of equity securities;

• authorizing the issuance of:

– shares giving access to our share capital or giving the right to receive debt instruments, or

– other securities giving access to our share capital;

• establishing any other rights to equity securities;

158 SANOFI FORM 20-F 2025

PART I
ITEM 10. Additional Information

• selling or transferring substantially all of our assets; and

• the voluntary liquidation of our Company.

Special meetings of shareholders of a certain category of shares or shares with certain specific rights (such as shares with double

voting rights) are required for any modification of the rights derived from that category of shares. The resolutions of the

shareholders’ general meeting affecting these rights are effective only after approval by the relevant special meeting.

Annual ordinary meetings

The French Commercial Code requires the Board of Directors to convene an annual ordinary general shareholders’ meeting to

approve the annual financial statements. This meeting must be held within six months of the end of each fiscal year.

The Board of Directors may also convene an ordinary or extraordinary general shareholders’ meeting upon proper notice at any

time during the year. If the Board of Directors fails to convene a shareholders’ meeting, our independent auditors may call the

meeting. In case of bankruptcy, the liquidator or court-appointed agent may also call a shareholders’ meeting in some instances.

In addition, any of the following may request the court to appoint an agent for the purpose of calling a shareholders’ meeting:

• one or several shareholders holding at least 5% of our share capital;

• duly qualified associations of shareholders who have held their shares in registered form for at least two years and who

together hold at least 1% of our voting rights;

• the works council in cases of urgency; or

• any interested party in cases of urgency.

Under our Articles of Association, the Board of Directors may take decisions by written consultation under the conditions

permitted by law and as specified in the Board Charter, including the possibility to convene an ordinary or extraordinary general

meeting.

Notice of shareholders’ meetings

All prior notice periods provided for below are minimum periods required by French law and cannot be shortened, except in case

of a public tender offer for our shares.

We must announce general meetings at least thirty-five days in advance by means of a preliminary notice (avis de réunion) , which

is published in the Bulletin des Annonces Légales Obligatoires , or BALO. The preliminary notice must first be sent to the French

Financial markets authority ( Autorité des marchés financiers , the “AMF”), with an indication of the date on which it will be

published in the BALO. It must be published on our website at least twenty-one days prior to the general meeting. The

preliminary notice must contain, among other things, the agenda, a draft of the resolutions to be submitted to the shareholders

for consideration at the general meeting and a detailed description of the voting procedures (proxy voting, electronic voting or

voting by mail), the procedures permitting shareholders to submit additional resolutions or items to the agenda and to ask written

questions to the Board of Directors. The AMF also recommends that, prior to or simultaneously with the publication of the

preliminary notice, we publish a summary of the notice indicating the date, time and place of the meeting in a newspaper of

national circulation in France and on our website.

At least fifteen days prior to the date set for a first convening, and at least ten days prior to any second convening, we must send

a final notice (avis de convocation) containing the final agenda, the date, time and place of the meeting and other information

related to the meeting. Such final notice must be sent by mail to all registered shareholders who have held shares in registered

form for more than one month prior to the date of the final notice and by registered mail, if shareholders have asked for it and

paid the corresponding charges. The final notice must also be published in a newspaper authorized to publish legal

announcements in the local administrative department (département) in which our Company is registered as well as in the BALO,

with prior notice having been given to the AMF for informational purposes. Even if there are no proposals for new resolutions or

items to be submitted to the shareholders at the meeting, we must publish a final notice in a newspaper authorized to publish

legal announcements in the local administrative department (département) in which our Company is registered as well as in

the BALO.

Other issues

In general, shareholders can only take action at shareholders’ meetings on matters listed on the agenda. As an exception to this

rule, shareholders may take action with respect to the appointment and dismissal of directors even if this action has not been

included on the agenda.

Additional resolutions to be submitted for approval by the shareholders at the shareholders’ meeting may be proposed to the

Board of Directors, for recommendation to the shareholders at any time from the publication of the preliminary notice in

the BALO until twenty-five days prior to the general meeting and in any case no later than twenty days following the publication

of the preliminary notice in the BALO by:

• one or several shareholders together holding a specified percentage of shares;

• a duly qualified association of shareholders who have held their shares in registered form for at least two years and who

together hold at least 1% of our voting rights; or

• the works council.

SANOFI FORM 20-F 2025 159

PART I
ITEM 10. Additional Information

Within the same period, the shareholders may also propose additional items ( points ) to be submitted and discussed during the

shareholders’ meeting, without a shareholders’ vote. The shareholders must substantiate the reasons for their proposals of

additional items.

The resolutions and the list of items added to the agenda of the shareholders’ meeting must be promptly published on

our website.

The Board of Directors must submit the resolutions to a vote of the shareholders after having made a recommendation thereon.

The Board of Directors may also comment on the items that are submitted to the shareholders’ meeting.

Following the date on which documents must be made available to the shareholders (including documents to be submitted to the

shareholders’ meeting and resolutions proposed by the Board of Directors, which must be published on our website at least

twenty-one days prior to the general meeting), shareholders may submit written questions to the Board of Directors relating to

the agenda for the meeting until the fourth business day prior to the general meeting. The Board of Directors must respond to

these questions during the meeting or may refer to a Q&A section located on our website in which the question submitted by a

shareholder has already been answered.

Attendance at shareholders’ meetings; proxies and votes by mail

In general, all shareholders may participate in general meetings either in person or by proxy. Shareholders may vote in person, by

proxy or by mail.

The right of shareholders to participate in general meetings is subject to the recording ( inscription en compte ) of their shares on

the fifth business day at 12:00 a.m. (Paris time), preceding the general meeting:

• for holders of registered shares: in the registered shareholder account held by the Company or on its behalf by an agent

appointed by it; and

• for holders of bearer shares: in the bearer shareholder account held by the accredited financial intermediary with whom such

holders have deposited their shares; such financial intermediaries shall deliver to holders of bearer shares a shareholding

certificate (attestation de participation) enabling them to participate in the general meeting.

Attendance in person

Any shareholder may attend ordinary general meetings and extraordinary general meetings and exercise its voting rights subject

to the conditions specified in the French Commercial Code, the French Civil Code and our Articles of Association.

An attendance sheet and written minutes are established for each shareholders’ meeting; failure to do so could lead to

cancellation of the decisions at the shareholders’ meeting.

Proxies and votes by mail

Proxies are sent to any shareholder upon a request received between the publication of the final notice of meeting and six days

before the general meeting and must be made available on our website at least twenty-one days before the general meeting. In

order to be counted, such proxies must be received at our registered office, or at any other address indicated on the notice of the

meeting or by any electronic mail indicated on the notice of the meeting, prior to the date of the meeting (in practice, we request

that shareholders return proxies at least three business days prior to the meeting; electronic proxies must be returned

before 3 p.m. Paris time, on the day prior to the general meeting). A shareholder may grant proxies to any natural person or legal

entity. The agent may be required to disclose certain information to the shareholder or to the public.

A proxy is only valid for one meeting (or by way of exception for two meetings, one being ordinary and the other extraordinary,

held on the same day or within a single 15-day period); it remains valid in the event such meeting is convened multiple times for

the same agenda, and may be revoked by written statement of the shareholder granting the proxy.

Alternatively, the shareholder may send us a blank proxy without nominating any representative. In this case, the chairman of the

meeting will vote the blank proxies in favor of all resolutions proposed or approved by the Board of Directors and against

all others.

With respect to votes by mail, we must send shareholders a voting form upon request or must make available a voting form on our

website at least twenty-one days before the general meeting. The completed form must be returned to us at least three days

prior to the date of the shareholders’ meeting. For holders of registered shares, in addition to traditional voting by mail,

instructions may also be given via the Internet.

Quorum

The French Commercial Code requires that shareholders holding in the aggregate at least 20% of the shares entitled to vote

must be present in person, or vote by mail or by proxy, in order to fulfill the quorum requirement for:

• an ordinary general meeting; and

• an extraordinary general meeting where the only resolutions pertain to either (a) a proposed increase in our share capital

through incorporation of reserves, profits or share premium, or (b) the potential issuance of free share warrants in the event of

a public tender offer for our shares (Article L. 233-32 of the French Commercial Code).

For any other extraordinary general meeting the quorum requirement is at least 25% of the shares entitled to vote, held by

shareholders present in person, voting by mail or by proxy.

160 SANOFI FORM 20-F 2025

PART I
ITEM 10. Additional Information

For a special meeting of holders of a certain category of shares, the quorum requirement is one third of the shares entitled to

vote in that category, held by shareholders present in person, voting by mail or by proxy.

If a quorum is not present at a meeting, the meeting is adjourned. However, only questions that were on the agenda of the

adjourned meeting may be discussed and voted upon once the meeting resumes.

When an adjourned meeting is resumed, there is no quorum requirement for meetings cited in the first paragraph of this

“Quorum” section. In the case of any other reconvened extraordinary general meeting or special meeting, the quorum

requirement is 20% of the shares entitled to vote (or voting shares belonging to the relevant category for special meetings of

holders of shares of such specific category), held by shareholders present in person or voting by mail or by proxy. If a quorum is

not met, the reconvened meeting may be adjourned for a maximum of two months with the same quorum requirement. No

deliberation or action by the shareholders may take place without a quorum.

C. Material Contracts

In the ordinary course of our business, we enter into agreements for licensing or collaboration in the development and

commercialization of products, as well as agreements for the purchase or sale of other businesses. Certain of the agreements

which have led to successful commercialization to date are summarized in “Item 5. Operating and financial review and prospects

— A.1.7 Financial presentation of alliances.”. Agreements in connection with the sale and purchase of a 50% controlling stake in

Opella are described in "Item 4. Information on the Company — B.3 Opella".

Share Repurchase Agreement with L'Oréal

On February 2, 2025, Sanofi and L'Oréal entered into a share buyback agreement pursuant to which Sanofi repurchased

29,556,650 shares from L’Oréal, a significant shareholder, at €101.50 per share, for a total amount of approximately €3 billion.

The transaction closed on February 5, 2025. Sanofi canceled the shares acquired from L'Oréal on March 13, 2025. As of

December 31, 2025, after the transaction and cancellation of the shares, L’Oréal held 7.27% of Sanofi’s share capital and 13.10% of

Sanofi’s effective voting rights (excluding treasury shares). For more information, see “Item 3. Key Information – D. Risk Factors –

Our largest shareholder owns a significant percentage of the share capital and voting rights of Sanofi” and “Item 7. Major

Shareholders and Related Party Transactions – A. Major Shareholders.”

D. Exchange Controls

French exchange control regulations currently do not limit the amount of payments that we may remit to non-residents of

France. Laws and regulations concerning foreign exchange controls do require, however, that all payments or transfers of funds

made by a French resident to a non-resident be handled by an accredited intermediary.

E. Taxation

General

The following generally summarizes the material French and US federal income tax consequences to US holders (as defined

below) of purchasing, owning and disposing of our ADSs and ordinary shares (collectively the “Securities”). This discussion is

intended only as a descriptive summary and does not purport to be a complete analysis or listing of all potential tax effects of the

purchase, ownership or disposition of our Securities. All of the following is subject to change. Such changes could apply

retroactively and could affect the consequences described below.

The French Finance Bill for 2026 ( Loi de finances pour 2026 ), adopted by the French Parliament on February 2, 2026, remains

subject to review by the French Constitutional Council prior to its official promulgation. However, no material amendments are

expected to result from such review, and the version currently adopted of the French Finance Bill for 2026 is not expected to

entail material tax consequences for US holders.

This summary does not constitute a legal opinion or tax advice. Holders are urged to consult their own tax advisers regarding

the tax consequences of the purchase, ownership and disposition of Securities in light of their particular circumstances,

including the effect of any US federal, state, local or other national tax laws.

A set of tax rules is applicable to French assets that are held by or in foreign trusts. These rules provide inter alia for the inclusion

of trust assets in the settlor’s net assets for purpose of applying the French real estate wealth tax, for the application of French

gift and death duties to French assets held in trust, for a specific tax on capital on the French assets of foreign trusts not already

subject to the French real estate wealth tax and for a number of French tax reporting and disclosure obligations. The following

discussion does not address the French tax consequences applicable to Securities held in trusts. If Securities are held in trust, the

grantor, trustee and beneficiary are urged to consult their own tax adviser regarding the specific tax consequences of acquiring,

owning and disposing of Securities.

The description of the French and US federal income tax consequences set forth below is based on the laws (including, for

US federal income tax purposes, the Internal Revenue Code of 1986, as amended (the “Code”), final, temporary and proposed

US Treasury Regulations promulgated thereunder and administrative and judicial interpretations thereof) in force as of the date

of this annual report, the Convention Between the Government of the United States of America and the Government of the

French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and

Capital of August 31, 1994 (the “Treaty”), which entered into force on December 30, 1995 (as amended by any subsequent

protocols, including the protocol of January 13, 2009), and the tax regulations issued by the French tax authorities within the

SANOFI FORM 20-F 2025 161

PART I
ITEM 10. Additional Information

Bulletin Officiel des Finances Publiques-Impôts (the “Regulations”) in force as of the date of this report. US holders are advised to

consult their own tax advisers regarding their eligibility for Treaty benefits, especially with regard to the “Limitations on

Benefits” provision, in light of their own particular circumstances.

No advance ruling has been obtained with respect to the tax consequences of the acquisition, ownership or disposition of the

Securities from either the French or US tax authorities. Thus, there can no assurances that either or both of such authorities will

not take a position concerning said tax consequences different from that set out herein or that such a position would not be

sustained by a court.

For the purposes of this discussion, a US holder is a beneficial owner of Securities that is (i) an individual who is a US citizen or

resident for US federal income tax purposes, (ii) a US domestic corporation created or organized in or under the laws of the

United States or any state thereof, including the District of Columbia, or (iii) certain estates or trusts that are subject to US tax

jurisdiction.

If a partnership holds Securities, the tax treatment of a partner generally will depend upon the status of the partner and the

activities of the partnership. If a US holder is an estate or trust or partner in a partnership that holds Securities, the holder is

urged to consult its own tax adviser regarding the specific tax consequences of acquiring, owning and disposing of Securities.

This discussion is intended only as a general summary and does not purport to be a complete analysis or listing of all potential tax

effects of the acquisition, ownership or disposition of the Securities to any particular investor, and does not discuss tax

considerations that arise from rules of general application or that are generally assumed to be known by investors. The discussion

applies only to investors that hold our Securities as capital assets that have the US dollar as their functional currency, that are

entitled to Treaty benefits under the “Limitation on Benefits” provision contained in the Treaty, and whose ownership of the

Securities is not effectively connected to a permanent establishment or a fixed base in France. Certain holders (including, but not

limited to, US expatriates, partnerships or other entities classified as partnerships for US federal income tax purposes, banks,

insurance companies, regulated investment companies, tax-exempt organizations, financial institutions, persons subject to the

alternative minimum tax, persons who acquired the Securities pursuant to the exercise of employee stock options or otherwise as

compensation, persons that own (directly, indirectly or by attribution) 5% or more of our voting stock or 5% or more of our

outstanding share capital, dealers in securities or currencies, persons that elect to mark their securities to market for US federal

income tax purposes, persons that acquire ADSs in “pre-release” transactions (i.e. prior to deposit of the relevant ordinary shares,

although our depositary has indicated that such transactions have been halted) and persons holding Securities as a position in a

synthetic security, straddle or conversion transaction) may be subject to special rules not discussed below. Holders of Securities

are advised to consult their own tax advisers with regard to the application of French tax law and US federal tax law to their

particular situations, as well as any tax consequences arising under the laws of any state, local or other foreign jurisdiction.

French taxes

Estate and gift taxes and transfer taxes

In general, a transfer of Securities by gift or by reason of death of a US holder that would otherwise be subject to French gift or

inheritance tax, respectively, will not be subject to such French tax by reason of the Convention between the Government of the

United States of America and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention

of Fiscal Evasion with Respect to Taxes on Estates, Inheritances and Gifts, dated November 24, 1978, unless the donor or the

transferor is domiciled in France at the time of making the gift or at the time of his or her death, or the Securities were used in, or

held for use in, the conduct of a business through a permanent establishment or a fixed base in France.

Pursuant to Article 235 ter ZD of the French General Tax Code, purchases of Securities are currently subject to a 0.3% French tax

on financial transactions (the “FTFF”). According to Article 26 quater of the Finance Bill for 2025, the rate of the FTFF will be

increased to 0.4% for purchases of Securities as from the first day of the second month following the enactment of the Finance

Bill for 2025. Purchases of Securities are subject to the FTFF provided that Sanofi’s market capitalization exceeds €1 billion as of

December 1 of the year preceding the taxation year. A list of companies whose market capitalization exceeds €1 billion as of

December 1 of the year preceding the taxation year used to be published annually by the French Ministry of Economy. It is now

published by the French tax authorities, and could be amended at any time. Pursuant to Regulations BOI-

ANNX-000467-17/12/2025 issued on December 17, 2025, purchases of Sanofi’s Securities in 2026 should be subject to the FTFF

as the market capitalization of Sanofi exceeded €1 billion as of December 1, 2025. In accordance with Article 726-II-d of the

French General Tax Code, purchases which are subject to the FTFF should however not be subject to transfer taxes (droits

d’enregistrement) in France.

Wealth tax

The French wealth tax (impôt de solidarité sur la fortune) has been replaced with a French real estate wealth tax (impôt sur la

fortune immobilière) with effect from January 1, 2018. French real estate wealth tax applies only to individuals and does not

generally apply to the Securities if the holder is a US resident, as defined pursuant to the provisions of the Treaty, provided that

the individual does not own directly or indirectly a shareholding exceeding 10% of the financial rights and voting rights.

162 SANOFI FORM 20-F 2025

PART I
ITEM 10. Additional Information

US taxes

Ownership of the securities

Deposits and withdrawals by a US holder of ordinary shares in exchange for ADSs, will not be taxable events for US federal

income tax purposes. For US tax purposes, holders of ADSs will be treated as owners of the ordinary shares represented by such

ADSs. Accordingly, the discussion that follows regarding the US federal income tax consequences of acquiring, owning and

disposing of ordinary shares is equally applicable to ADSs.

Information reporting and backup withholding tax

Distributions made to holders and proceeds paid from the sale, exchange, redemption or disposal of Securities may be subject to

information reporting to the Internal Revenue Service. Such payments may be subject to backup withholding taxes unless the holder

(i) is a corporation or other exempt recipient or (ii) provides a taxpayer identification number and certifies that no loss of exemption

from backup withholding has occurred. Holders that are not US persons generally are not subject to information reporting or backup

withholding. However, such a holder may be required to provide a certification of its non-US status in connection with payments

received within the United States or through a US-related financial intermediary to establish that it is an exempt recipient. Backup

withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s US federal income

tax liability. A holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the

appropriate claim for refund with the Internal Revenue Service and furnishing any required information.

Foreign asset reporting

In addition, a US holder that is an individual or certain entities may be subject to reporting obligations with respect to ordinary

shares and ADSs if the aggregate value of these and certain other “specified foreign financial assets” exceeds $50,000 on

the last day of the tax year or more than $75,000 at any time during the tax year. If required, this disclosure is made by

filing Form 8938 with the US Internal Revenue Service. Significant penalties can apply if holders are required to make this

disclosure and fail to do so. In addition, a US holder should consider the possible obligation to file online a FinCEN Form 114 –

Foreign Bank and Financial Accounts Report as a result of holding ordinary shares or ADSs. Holders are encouraged to consult

their US tax advisors with respect to these and other reporting requirements that may apply to their acquisition of ordinary shares

and ADSs.

State and local taxes

In addition to US federal income tax, US holders of Securities may be subject to US state and local taxes with respect to such

Securities. Holders of Securities are advised to consult their own tax advisers with regard to the application of US state and local

income tax law to their particular situation.

ADSs-Ordinary Shares

French taxes

Taxation of dividends

Under French law, dividends paid by a French corporation, such as Sanofi, to non-residents of France are generally subject to

French withholding tax at a rate of (i) 25% for payments benefiting legal persons who are beneficial owners and are not French

tax residents (and 15% for distributions made to not-for-profit organizations with a head office in a Member State of the European

Economic Area which would be subject to the tax regime set forth under Article 206 paragraph 2 of the French General Tax Code

if its head office were located in France and which meet the criteria set forth in the Regulations BOI-RPPM-

RCM-30-30-10-70-24/12/2019, No. 130), and (ii) 12.8% for payments benefiting individuals who are beneficial owners and are not

French tax residents. Dividends paid by a French corporation, such as Sanofi, towards non-cooperative States or territories, as

defined in Article 238-0 A of the French General Tax Code (other than those mentioned in 2° of 2 bis of the same Article 238-0 A

of the French Tax Code), will generally be subject to French withholding tax at a rate of 75%, irrespective of the tax residence of

the beneficiary of the dividends if the dividends are received in such States or territories; however, eligible US holders entitled to

Treaty benefits under the “Limitation on Benefits” provision contained in the Treaty who are US residents, as defined pursuant to

the provisions of the Treaty and who receive dividends in non-cooperative States or territories, will not be subject to this 75%

withholding tax rate.

Under the Treaty, the rate of French withholding tax on dividends paid to an eligible US holder who is a US resident as defined

pursuant to the provisions of the Treaty and whose ownership of the ordinary shares or ADSs is not effectively connected with a

permanent establishment or fixed base that such US holder has in France, is reduced to 15%, or to 5% if such US holder is a

corporation and owns directly or indirectly at least 10% of the share capital of the issuing company; such US holder may claim a

refund from the French tax authorities of the amount withheld in excess of the Treaty rates of 15% or 5%, if any. For US holders

that are not individuals but are US residents, as defined pursuant to the provisions of the Treaty, the requirements for eligibility

for Treaty benefits, including the reduced 5% or 15% withholding tax rates contained in the “Limitation on Benefits” provision

of the Treaty, are complicated, and certain technical changes were made to these requirements by the protocol of

January 13, 2009. US holders are advised to consult their own tax advisers regarding their eligibility for Treaty benefits in light of

their own particular circumstances.

SANOFI FORM 20-F 2025 163

PART I
ITEM 10. Additional Information

Dividends paid to an eligible US holder may immediately be subject to the reduced rates of 5% or 15% provided that such holder

establishes before the date of payment that it is a US resident under the Treaty by completing and providing the depositary with

a treaty form (Form 5000). Dividends paid to a US holder that has not filed the Form 5000 before the dividend payment date will

be subject to French withholding tax at the rate of 25% and then reduced at a later date to 5% or 15%, provided that such holder

duly completes and provides the French tax authorities with the treaty forms Form 5000 and Form 5001 (due to recent case law

regarding the status of limitations for filing a withholding tax claim, US holders are advised to consult their own tax advisors in this

respect). Pension funds and certain other tax-exempt entities are subject to the same general filing requirements as other

US holders except that they may have to supply additional documentation evidencing their entitlement to these benefits.

The depositary agrees to use reasonable efforts to follow the procedures established, or that may be established, by the French

tax authorities (i) to enable eligible US holders to qualify for the reduced withholding tax rate provided by the Treaty, if available

at the time the dividends are paid, or (ii) to recover any excess French withholding taxes initially withheld or deducted with

respect to dividends and other distributions to which such US holders may be eligible from the French tax authorities and (iii) to

recover any other available tax credits. In particular, associated forms (including Form 5000 and Form 5001, together with their

instructions), will be made available by the depositary to all US holders registered with the depositary, and are also generally

available from the US Internal Revenue Service.

The withholding tax refund, if any, ordinarily is paid within 12 months of filing the applicable French Treasury Form, but not before

January 15 of the year following the calendar year in which the related dividend is paid.

In addition, please note that, pursuant to Article 235 quater of the French Tax Code and under certain conditions (in particular, in

addition to certain reporting obligations, the interest held in the distributing company must not enable the beneficiary to

participate effectively in the management or control of that company and the beneficiary company must be located in a country

that has signed an administrative assistance agreement with France to combat tax evasion and avoidance, as well as an

administrative assistance agreement on tax collection, and that is not a non-cooperative country), a corporate US holder in a tax

loss position or whose tax result is nil due to offset of tax losses for the fiscal year during which the dividend is received may be

entitled to a deferral regime, and obtain a withholding tax refund. The tax deferral ends in respect of the first financial year during

which this US holder is in a profit making position, as well as in the cases set out in Article 235 quater of the French Tax Code. The

refund must be claimed within the same period applicable to claims related to taxes other than local taxes. Also, pursuant to

Article 235 quinquies of the French Tax Code and under certain conditions, a corporate US holder may be entitled to a refund of

a fraction of the withholding tax, up to the difference between the withholding tax paid (on a gross basis) and the withholding tax

based on the dividend net of the expenses incurred for the acquisition and conservation directly related to the income, provided

(i) that these expenses would have been tax deductible had the US holder been established in France, and (ii) that the tax rules in

the United States do not allow the US holder to offset the withholding tax.

Given the special features of the ADSs, US holders are urged to consult their own tax advisor about the possible application to

ADSs of such provisions in light of their own circumstances.

Tax on sale or other disposition

In general, under the Treaty, a US holder who is a US resident for purposes of the Treaty will not be subject to French tax on any

capital gain from the redemption (other than redemption proceeds characterized as dividends under French domestic law), sale

or exchange of ordinary shares or ADSs unless the ordinary shares or the ADSs form part of the business property of a permanent

establishment or fixed base that the US holder has in France. Special rules apply to holders who are residents of more than

one country.

US Taxes

Taxation of dividends

For US federal income tax purposes, the gross amount of any distribution paid to US holders (that is, the net distribution received

plus any tax withheld therefrom) will be treated as ordinary dividend income to the extent paid or deemed paid out of the current

or accumulated earnings and profits of Sanofi (as determined under US federal income tax principles). Dividends paid by Sanofi

will not be eligible for the dividends-received deduction generally allowed to corporate US holders.

Subject to certain exceptions for short-term and hedged positions, the US dollar amount of dividends received by an individual

US holder with respect to the ADSs or our ordinary shares is currently subject to taxation at a maximum rate of 20% if the

dividends are “qualified dividends”. Dividends paid on the ordinary shares or ADSs will be treated as qualified dividends if (i) the

issuer is eligible for the benefits of a comprehensive income tax treaty with the US that the Internal Revenue Service has

approved for the purposes of the qualified dividend rules and (ii) the issuer was not, in the year prior to the year in which the

dividend was paid, and is not, in the year in which the dividend is paid, a passive foreign investment company (PFIC). The Treaty

has been approved for the purposes of the qualified dividend rules. Based on our financial statements and relevant market and

shareholder data, we believe Sanofi was not a PFIC for US federal income tax purposes with respect to its 2024 taxable year. In

addition, based on its current expectations regarding the value and nature of its assets, the sources and nature of its income, and

relevant market and shareholder data, we do not anticipate that Sanofi will become a PFIC for its 2025 taxable year. Holders of

ordinary shares and ADSs should consult their own tax advisers regarding the availability of the reduced dividend tax rate in

light of their own particular circumstances.

164 SANOFI FORM 20-F 2025

PART I
ITEM 10. Additional Information

If you are a US holder, dividend income received by you with respect to ADSs or ordinary shares generally will be treated as

foreign source income for foreign tax credit purposes. The limitation on foreign taxes eligible for credit is calculated separately

with respect to specific classes of income. Distributions out of earnings and profits with respect to the ADSs or ordinary shares

generally will be treated as “passive category” income (or, in the case of certain US holders, “general category” income). Subject

to certain limitations and the Foreign Tax Credit Regulations (as defined below), French income tax withheld in connection with

any distribution with respect to the ADSs or ordinary shares may be claimed as a credit against the US federal income tax liability

of a US holder if such US holder elects for that year to credit all foreign income taxes. Alternatively, such French withholding tax

may be taken as a deduction against taxable income. Foreign tax credits will not be allowed for withholding taxes imposed in

respect of certain short-term or hedged positions in Securities and may not be allowed in respect of certain arrangements in

which a US holder’s expected economic profit is insubstantial. Further, certain Treasury regulations addressing foreign tax credits

(the "Foreign Tax Credit Regulations") impose additional requirements for foreign taxes to be eligible for a foreign tax credit if the

relevant taxpayer does not elect to apply the benefits of an applicable income tax treaty, and there can be no assurance that

those requirements will be satisfied. Recent notices from the Internal Revenue Service provide temporary relief by allowing

taxpayers that comply with applicable requirements to apply many aspects of the foreign tax credit regulations as they previously

existed (before the release of the current Foreign Tax Credit Regulations) for taxable years ending before the date that a notice

or other guidance withdrawing or modifying the temporary relief is issued (or any later date specified in such notice or other

guidance). The US federal income tax rules governing the availability and computation of foreign tax credits are complex.

US holders should consult their own tax advisers concerning the implications of these rules, including the Foreign Tax Credit

Regulations and the related temporary relief in the Internal Revenue Service notices, in light of their particular circumstances.

To the extent that an amount received by a US holder exceeds the allocable share of our current and accumulated earnings and

profits, such excess will be applied first to reduce such US holder’s tax basis in its ordinary shares or ADSs and then, to the extent

it exceeds the US holder’s tax basis, it will constitute capital gain from a deemed sale or exchange of such ordinary shares or ADSs

(see “— Tax on Sale or Other Disposition”, below).

The amount of any distribution paid in euros will be equal to the US dollar value of the euro amount distributed, calculated by

reference to the exchange rate in effect on the date the dividend is received by a US holder of ordinary shares (or by the

depositary, in the case of ADSs) regardless of whether the payment is in fact converted into US dollars on such date. US holders

should consult their own tax advisers regarding the treatment of foreign currency gain or loss, if any, on any euros received by a

US holder that are converted into US dollars on a date subsequent to receipt.

Distributions to holders of additional ordinary shares (or ADSs) with respect to their ordinary shares (or ADSs) that are made as

part of a pro rata distribution to all ordinary shareholders generally will not be subject to US federal income tax. However, if a

US holder has the option to receive a distribution in shares (or ADSs) or to receive cash in lieu of such shares (or ADSs), the

distribution of shares (or ADSs) will be taxable as if the holder had received an amount equal to the fair market value of the

distributed shares (or ADSs), and such holder’s tax basis in the distributed shares (or ADSs) will be equal to such amount.

Tax on sale or other disposition

In general, for US federal income tax purposes, a US holder that sells, exchanges or otherwise disposes of its ordinary shares

or ADSs will recognize capital gain or loss in an amount equal to the US dollar value of the difference between the amount realized

for the ordinary shares or ADSs and the US holder’s adjusted tax basis (determined in US dollars and under US federal income tax

rules) in the ordinary shares or ADSs. Such gain or loss generally will be US-source gain or loss, and will be treated as long-term

capital gain or loss if the US holder’s holding period in the ordinary shares or ADSs exceeds one year at the time of disposition. If

the US holder is an individual, any capital gain generally will be subject to US federal income tax at preferential rates (currently a

maximum of 20%) if specified minimum holding periods are met. The deductibility of capital losses is subject to significant

limitations.

Medicare tax

Certain US holders who are individuals, estates or trusts are required to pay a Medicare tax of 3.8% (in addition to taxes they

would otherwise be subject to) on their “net investment income” which would include, among other things, dividends and capital

gains from the ordinary shares and ADSs.

PART I
ITEM 11. Quantitative and Qualitative Disclosures about Market Risk

Item 11. Quantitative and Qualitative Disclosures about Market Risk (1)

General Policy

Liquidity risk, foreign exchange risk and interest rate risk, as well as related counterparty risks, are managed centrally by our

dedicated treasury team within the Group Finance Department. Where it is not possible to manage those risks centrally – in

particular due to regulatory restrictions (such as foreign exchange controls) or local tax restrictions – credit facilities and/or

currency lines, guaranteed whenever necessary by the parent company, are contracted by our subsidiaries locally with banks,

under the supervision of the central treasury team.

Our financing and investment strategies, and our interest rate and currency hedging strategies, are reviewed monthly by the

Group Finance Department.

Our policy prohibits the use of derivatives for speculative purposes.

Counterparty Risk

Our financing and investing transactions, and our currency and interest rate hedges, are contracted with leading counterparties.

We set limits for investment and derivative transactions with individual financial institutions, depending on the rating of each

institution. Compliance with these limits, which are based on the notional amounts of the investments and the fair value of the

hedging instruments, is monitored on a daily basis.

The table below shows our total exposure as of December 31, 2025 by rating and in terms of our percentage exposure to the

dominant counterparty.

(a) Cash equivalents include mutual fund investments of € 5,820 million.

(b) The notional amounts are translated into euros at the relevant closing exchange rate as of December 31, 2025 .

As of December 31, 2025 , Sanofi held investments in euro and US dollar denominated money-market mutual funds. Those

instruments have low volatility, low sensitivity to interest rate risk, and a very low probability of loss of principal. The depositary

banks of the mutual funds, and of Sanofi itself, have a long-term rating of at least A. Realization of counterparty risk could impact

our liquidity in certain circumstances.

Foreign Exchange Risk

A. Operating foreign exchange risk

A substantial portion of our net sales is generated in countries where the euro, which is our reporting currency, is not the

functional currency. In 2025 , for example, 50.8% of our net sales were generated in the US; 21.0% in Europe; and 28.2% in the

Rest of the World region (see the definition in “Item 5. Operating and Financial Review and Prospects — A. Operating results),

including countries that are, or may in the future become, subject to exchange controls, of which 6.0% was generated in China

and 3.2% in Japan. Although we also incur expenses in those countries, the impact of those expenses is not enough wholly to

offset the impact of exchange rates on our net sales. Consequently, our operating income may be materially affected by

fluctuations in exchange rates between the euro and other currencies. Sanofi operates a foreign exchange risk hedging policy to

reduce the exposure of operating income to exchange rate movements. That policy involves regular assessments of Sanofi’s

worldwide foreign currency exposure, based on foreign currency transactions carried out by the parent company and its

subsidiaries. Those transactions mainly comprise sales, purchases, research costs, co-marketing and co-promotion expenses, and

royalties. To reduce the exposure of those transactions to exchange rate movements, Sanofi contracts hedges using liquid

derivative instruments, mainly forward currency purchases and sales, and also foreign exchange swaps. See also “Item 5.

Operating and Financial Review and Prospects — A. Operating results — A.1.8 Impact of Exchange Rates.”

The table below shows operating currency hedging instruments in place as of December 31, 2025 , with the notional amount

translated into euros at the relevant closing exchange rate (see Note D.20. to our consolidated financial statements included at

Item 18. of this annual report, for the accounting classification of those instruments as of December 31, 2025 ).

The above positions mainly hedge future material foreign-currency cash flows arising after the end of the reporting period in

relation to transactions carried out during the year ended December 31, 2025 and recognized in the balance sheet at that date.

Gains and losses on hedging instruments (forward contracts) are calculated and recognized in parallel with the recognition of

gains and losses on the hedged items. Due to this hedging relationship, the commercial foreign exchange profit or loss on these

items (hedging instruments and hedged transactions) will be immaterial in 2026 .

B. Financial foreign exchange risk

The cash pooling arrangements for foreign subsidiaries outside the euro zone, and some of Sanofi’s financing activities, expose

certain Sanofi entities to financial foreign exchange risk (i.e. the risk of changes in the value of borrowings and loans denominated

in a currency other than the functional currency of the borrower or lender). That foreign exchange exposure is hedged using

derivative instruments (foreign exchange swaps, forward contracts or cross currency swaps) that alter the currency split of

Sanofi’s net debt once those instruments are taken into account.

The table below shows financial currency hedging instruments in place as of December 31, 2025 , with the notional amounts

translated into euros at the relevant closing exchange rate (see also Note D.20. to our consolidated financial statements included

at Item 18. of this annual report, for the accounting classification of these instruments as of December 31, 2025 ).

with a notional amount of $870 million , pay 4.53% in US dollars and receive 3.00% in euros, expiring 2032, designated as a hedge of Sanofi’s net

investment in the US. As of December 31, 2025, the fair value of the swaps was an asset of €6 million , with €9 million credited to Other comprehensive

income and €3 million debited to financial income and expenses.

(b) Includes forward sales with a notional amount of $11,275 million expiring in 2026 and 2027 , designated as a hedge of Sanofi’s net investment in the US.

As of December 31, 2025 , the fair value of these forward contracts represented a liability of €30 million , of which €30 million debited to Other

comprehensive income , with the impact on financial income and expenses being immaterial.

(c) Includes forward purchases with a notional amount of $ 1,000 million expiring in 2026 , designated as a fair value hedge of the exposure of $ 1,000 million

of bond issues to fluctuations in the EUR/USD spot rate. As of December 31, 2025 , the fair value of the contracts was an asset of € 3 million , of which

€1 million was credited to Other comprehensive income under the cost of hedging accounting treatment.

These hedging instruments generate a net financial gain or loss arising from the interest rate differential between the hedged

currency and the euro, given that the foreign exchange gain or loss on the foreign-currency borrowing and loans is offset by the

change in the intrinsic value of the hedging instruments. The interest rate differential is recognized within cost of net debt

(see Note D.29. to our consolidated financial statements included at Item 18. of this annual report). We may also hedge some

future foreign-currency investment or divestment cash flows.

168 SANOFI FORM 20-F 2025

PART I
ITEM 11. Quantitative and Qualitative Disclosures about Market Risk

C. Other foreign exchange risks

A significant proportion of our net assets is denominated in US dollars (see Note D.35. to the consolidated financial statements

included at Item 18. of this annual report). As a result, any fluctuation in the exchange rate of the US dollar against the euro

automatically impacts the amount of our equity as expressed in euros; however, the impact is partially hedged by transactions

designated as hedges of Sanofi’s net investment in the US (see "B.— Financial foreign exchange risk" above, and Note D17.1. to

the consolidated financial statements included at Item 18. of this annual report).

In addition, we use the euro as our reporting currency. Consequently, if one or more EU Member States were to abandon the euro

as a currency, the resulting economic upheavals – in particular, fluctuations in exchange rates – could have a significant impact

on the terms under which we can obtain financing and on our financial results, the extent and consequences of which are not

currently foreseeable.

Liquidity Risk

We operate a centralized treasury platform whereby all surplus cash and financing needs of our subsidiaries are invested with or

funded by the parent company (where permitted by local legislation). The central treasury department manages our current and

projected financing, and ensures that Sanofi is able to meet its financial commitments by maintaining sufficient cash and

confirmed credit facilities for the size of our operations and the maturity of our debt (see Notes D.17.1.c. and D.17.1.g. to the

consolidated financial statements included at Item 18. of this annual report).

We diversify our short-term investments with leading counterparties using money-market products with instant access, or with a

maturity of most often less than three months.

As of December 31, 2025 , cash and cash equivalents amounted to € 7,657 million , and short-term investments predominantly comprised:

• collective investments in euro and US dollar denominated money-market mutual funds. All such funds can be traded on a daily

basis and the amount invested in each fund may not exceed 10% of each fund's net asset value ; and

• amounts invested directly with banks in the form of instant access deposits, and term deposits with a maturity of no more than

three months.

As of December 31, 2025 , we also had €8 billion of undrawn general corporate purpose confirmed credit facilities, half of which

expires in December 2027 and half in March 2030. Those credit facilities are not subject to financial covenant ratios.

Our policy is to diversify our sources of funding through public or private issuances of debt securities, in the US (shelf registration

statement) and Europe (Euro Medium Term Note program). In addition, our A-1+/P-1/S-1+ (by Standard & Poor’s/Moody’s/Scope

Ratings respectively) short-term rating gives us access to commercial paper programs in the US, and to Negotiable European

Commercial Paper programs in France. The average maturity of our total debt was 3.58 years as of December 31, 2025 ,

compared with 3.56 years as of December 31, 2024 .

Average drawdowns under the Negotiable European Commercial Paper program in France during 2025 were €0.1 billion (with a

maximum of €0.2 billion); the average maturity of those drawdowns was three months. As of December 31, 2025 , this program

was not being utilized.

Average drawdowns under the US Commercial Paper program during 2025 were $3.8 billion (with a maximum of $6.8 billion);

the average maturity of those drawdowns was two months. As of December 31, 2025 , drawdowns under the program amounted

to $1.0 billion.

In the event of a liquidity crisis, we could be exposed to difficulties in calling up our available cash, a scarcity of sources of funding

including the above-mentioned programs, and/or a deterioration in their terms. This situation could damage our capacity to

refinance our debt or to issue new debt on reasonable terms.

Interest Rate Risk

Sanofi issues debt in two currencies, the euro and the US dollar, and also invests its cash and cash equivalents in those currencies.

Sanofi also operat es cash pooling arrangements to manage the surplus cash and short-term liquidity needs of foreign subsidiaries

located outside the euro zone.

To optimize the cost of debt or reduce the volatility of debt and manage its exposure to financial foreign exchange risk, Sanofi

uses derivative instruments (interest rate swaps, currency swaps, foreign exchange swaps and forward contracts) that alter the

fixed/floating rate split and the currency split of its net debt.

The projected full-year sensitivity to interest rate fluctuations of our debt, net of cash and cash equivalents for 2026 is as follows:

Change in short-term interest rates	Impact on pre-tax net income (€ million)	Impact on pre-tax income/(expense) recognized directly in equity (€ million)
+100 bp	50	27
+25 bp	12	7
-25 bp	(12)	(7)
-100 bp	(50)	(27)

Stock Market Risk

It is our policy not to trade on the stock market for speculative purposes.

General

JPMorgan Chase Bank, NA (“JPMorgan”), as depositary, issues Sanofi ADSs in certificated form (evidenced by an ADR) or book-

entry form. Each ADR is a certificate evidencing a specific number of Sanofi ADSs. Each Sanofi ADS represents one-half of one

Sanofi ordinary share (or the right to receive one-half of one Sanofi ordinary share) deposited with the Paris, France office of BNP

Paribas, as custodian. Each Sanofi ADS also represents an interest in any other securities, cash or other property that may

be held by the depositary under the Second Amended and Restated Deposit Agreement between Sanofi and JPMorgan

dated February 13, 2015, as amended by Amendment No. 1 dated July 23, 2020 (“Amendment No. 1”), Amendment No. 2

dated December 18, 2023 ("Amendment No. 2"), and as may be further amended from time to time (together, the “deposit

agreement”). The depositary’s principal executive office is located at 383 Madison Avenue, 11th Floor, New York, New York 10179.

For additional information on our ADSs, please refer to Exhibit 2.2 “Description of securities registered under section 12 of the

Exchange Act.” of this Annual Report.

Fees and expenses

Fees payable by ADS holders

Pursuant to the deposit agreement, holders of our ADSs may have to pay to JPMorgan, either directly or indirectly, fees, charges

and expenses up to the amounts set forth in the table below.

Associated Fee	Depositary Action
$5.00 or less per 100 ADSs (or portion thereof)	The deposit of shares and/or the execution and delivery of ADRs (pursuant to distribution in shares or distribution of rights to subscribe for additional shares, or distribution of any rights of any other nature), and/or the reduction of ADSs and surrender of ADRs for the purposes of withdrawal, including the termination of the deposit agreement.
$0.05 or less per ADS (or portion thereof)	Any distribution made pursuant to the deposit agreement, including, among other things: • any cash distribution made, or for any elective cash/stock dividend offered; and • the direct or indirect distribution of securities (other than ADSs or rights to purchase additional ADSs) or the net cash proceeds from the public or private sale of any such securities.
$0.05 or less per ADS per calendar year (or portion thereof)	Services performed in administering the ADRs (which fee may be charged on a periodic basis during each calendar year).
An amount for the reimbursement of such fees, charges and expenses as are incurred by JPMorgan and/or any of its agents (including, without limitation BNP Paribas, as custodian and expenses incurred on behalf of owners in connection with compliance with foreign exchange control regulations or any law or regulation relating to foreign investment)	Compliance with foreign exchange control regulations or any law or regulation relating to foreign investment, servicing of shares or other deposited securities, sale of securities, delivery of deposited securities or otherwise.
Expenses incurred by JPMorgan	Foreign currency conversion into dollars.

The Depositary may sell (by public or private sale) sufficient securities and property received in respect of Share distributions,

rights and other distributions prior to a deposit to pay any charge owing.

In addition to the fees outlined above, each holder will be responsible for any taxes or other governmental charges payable on his

or her Sanofi ADSs or on the deposited securities underlying his or her Sanofi ADSs. The depositary may refuse to transfer a

holder’s Sanofi ADSs or allow a holder to withdraw the deposited securities underlying his or her Sanofi ADSs until such taxes or

other charges are paid. It may apply payments owed to a holder or sell deposited securities underlying a holder’s Sanofi ADSs to

pay any taxes owed, and the holder will remain liable for any deficiency. If it sells deposited securities, it will, if appropriate, reduce

ITEM 12. Description of Securities other than Equity Securities

Fees paid to Sanofi by the depositary

JPMorgan, as depositary, has agreed to reimburse Sanofi for certain expenses that Sanofi incurs relating to the establishment and

maintenance of the ADR program, as agreed from time to time. Pursuant to a letter agreement dated October 4, 2022 (the “letter

agreement”), JPMorgan as our ADS depositary has agreed to make (i) an initial contribution to Sanofi, within 30 days of the

commencement date of the letter agreement and (ii) with respect to each 12-month period beginning on the anniversary of the

effective date of the agreement (each such 12-month period, a “Contract Year”), a contribution, paid at the end of such Contract

Year quarter, equal to the aggregate of the program share (equal to 100% of routine program revenues and 50% of non-routine

program revenues) of any program revenues, less the aggregate of any program costs for the applicable Contract Year and any

invoiced supplementary costs not paid within 60 days of the date of the applicable invoice.

To the extent in any given Contract Year the depositary does not collect/recoup the entirety of the program costs and unpaid

supplementary costs, no contribution shall be payable to Sanofi and such excess will, at the discretion of the depositary, either be

deducted from future contributions or be payable to the depositary by Sanofi promptly upon invoicing as supplementary costs

under the letter agreement.

JPMorgan has further agreed to waive the $0.05 per ADS issuance fees that would normally be owed by Sanofi in connection

with our deposits of shares as part of our employee stock purchase plans. Sanofi is responsible for reimbursing JPMorgan for all

taxes and governmental charges in connection with payments to JPMorgan under the letter agreement.

From January 1, 2025 to December 31, 2025 , we received a total amount of $23,930,596.45 from JPMorgan pursuant to the letter

agreement.

A. Disclosure Controls and Procedures

Our Chief Executive Officer and Principal Financial Officer, after evaluating the effectiveness of our disclosure controls and

procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this Form 20-F, have concluded

that, as of such date, our disclosure controls and procedures were effective to ensure that material information relating to Sanofi

was timely made known to them by others within Sanofi.

B. Management’s Annual Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control over financial

reporting, as such term is defined in Exchange Act Rule 13a-15(f). Management assessed the effectiveness of internal control over

financial reporting as of December 31, 2025 based on the framework in “Internal Control — Integrated

Framework” (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Blueprint Medicines (Blueprint Medicines Corporation and its affiliates), acquired in 2025, has been excluded from the scope of

management’s assessment and conclusion on internal control over financial reporting as of December 31, 2025. Blueprint is

included in the 2025 consolidated financial statements of the Company; it represents less than 1% of total assets as of December

31, 2025 and less than 1% of net sales for the year then ended.

Based on that assessment, management has concluded that the Company’s internal control over financial reporting was

effective as of December 31, 2025 to provide reasonable assurance regarding the reliability of its financial reporting and the

preparation of its financial statements for external purposes, in accordance with generally accepted accounting principles.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements, and can only

provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements. Also,

projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate

because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The effectiveness of the Company’s internal control over financial reporting has been audited by PricewaterhouseCoopers Audit

(PCAOB ID 1347 ) and Forvis Mazars SA (PCAOB ID 1334 ) independent registered public accounting firms, as stated in their report

on the Company’s internal control over financial reporting as of December 31, 2025 , which is included herein. See paragraph (c) of

the present Item 15., below.

C. Attestation Report of the Registered Public Accounting Firm

The effectiveness of the Company's internal control over financial reporting as of December 31, 2025 has been audited by

D. Changes in Internal Control over Financial Reporting

There were no changes to the Company's internal control over financial reporting that occurred during the period covered by this

Form 20-F that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

SANOFI FORM 20-F 2025 175

PART II
Item 16G. Corporate Governance

Item 16G. Corporate Governance

Sanofi is incorporated under the laws of France, with securities listed on regulated public markets in the United States (Nasdaq

Global Select Market – NASDAQ) and France (Euronext Paris). Consequently, as described further in this annual report, our

corporate governance framework reflects the mandatory provisions of French corporate law, the securities laws and regulations

of France and the United States and the rules of the aforementioned public markets.

As a “foreign private issuer”, as defined in the rules promulgated under the Exchange Act, Sanofi is permitted, pursuant to

NASDAQ Listing Rule 5615(a)(3), to follow its home country practice in lieu of certain NASDAQ corporate governance

requirements applicable to US corporations listed on the NASDAQ. Sanofi has informed NASDAQ that it intends to follow

corporate governance standards under French law to the extent permitted by the NASDAQ listing rules and US securities laws, as

further discussed below.

We generally follow the “AFEP-MEDEF” corporate governance recommendations for French listed issuers (hereafter referred to

as the “AFEP-MEDEF Code”). As a result, our corporate governance framework is similar in many respects to, and provides

investor protections that are comparable to – or in some cases, more stringent than – the corresponding rules of the NASDAQ.

Nevertheless, there are certain important differences.

In line with NASDAQ listing rules applicable to domestic issuers, a majority of Sanofi’s Board of Directors is comprised of

independent directors. Sanofi evaluates the independence of members of our Board of Directors using the standards of the

French AFEP-MEDEF Code as the principal reference. We believe that AFEP-MEDEF’s overarching criteria for independence –

that Board members have no relationship of any kind whatsoever with the Company, its group or the management of either such

a s to color a Board member’s judgment – is on the whole consistent with the goals of the NASDAQ's listing rules; however, the

specific tests proposed under the two standards may vary on some points. Our Audit Committee complies with

the independence and other requirements of Rule 10A-3 under the Exchange Act, adopted pursuant to the Sarbanes-Oxley

Act of 2002. Our Audit Committee includes one member, Christophe Babule, who is considered non-independent under the

AFEP-MEDEF Code, and which is permitted under the AFEP-MEDEF Code. Three out of the four members of our Compensation

Committee meet the independence standards of the AFEP-MEDEF Code (the Director representing employees is not

considered as independent) and the independence requirements of NASDAQ’s listing rules.

Sanofi follows the recommendation of the AFEP-MEDEF Code that at least one meeting of the Board of Directors not attended

by the company’s executive officers be organized each year. Accordingly, Sanofi’s Board Charter provides that the Board of

Directors shall organize at least two meetings a year without its executive officers, thereby providing the Chairman with the

option of whether to include directors representing employees or any other Group employee, as the case may require,

depending on the agenda of the meeting. Sanofi’s practice in that respect departs from NASDAQ Listing Rule 5605(b)(2), which

provides that independent directors must have regularly scheduled meetings at which only independent directors are present.

Under French law, the committees of our Board of Directors are advisory only, and where the NASDAQ Listing Rule 5600 series

would vest certain decision-making powers with specific committees by delegation (e.g. the appointment of Sanofi’s auditors by

the Audit Committee), under French law, our Board of Directors remains the only competent body to take such decisions, albeit

taking into account the recommendation of the relevant committees. Additionally, under French corporate law, it is the

shareholders of Sanofi voting at the Shareholders’ General Meeting that have the authority to appoint our auditors upon

consideration of the proposal of our Board of Directors, although our Board Charter provides that the Board of Directors will

make its proposal on the basis of the recommendation of our Audit Committee. We believe that this requirement of French law,

together with the additional legal requirement that two sets of statutory auditors be appointed, is in line with the NASDAQ's

underlying goal of ensuring that the audit of our accounts be conducted by auditors independent from company management.

NASDAQ Listing Rule 5635 requires a NASDAQ listed company to obtain shareholder approval prior to certain issuances of

securities, including: (a) issuances in connection with the acquisition of the stock or assets of another company if upon issuance

the issued shares will equal 20% or more of the number of shares or voting power outstanding prior to the issuance, or if certain

specified persons have a 5% or greater interest in the assets or company to be acquired (NASDAQ Listing Rule 5635(a));

(b) issuances or potential issuances that will result in a change of control of us (NASDAQ Listing Rule 5635(b)); (c) issuances in

connection with equity compensation arrangements (NASDAQ Listing Rule 5635(c)); and (d) 20% or greater issuances in

transactions other than public offerings, as defined in the NASDAQ listing rules (NASDAQ Listing Rule 5635(d)). Under French

law, our shareholders may approve issuances of equity, as a general matter, through the adoption of delegation of authority

resolutions at the Company’s shareholders’ meeting pursuant to which shareholders may delegate their authority to the Board

of Directors to increase the Company’s share capital within specified parameters set by the shareholders, which may include a

time limitation to carry out the share capital increase, the cancellation of their preferential subscription rights to the benefit of

named persons or a category of persons, specified price limitations and/or specific or aggregate limitations on the size of the

share capital increase. Due to differences between French law and corporate governance practices and NASDAQ Listing

Rule 5635, the Company follows French home country practice, rather than complying with this NASDAQ Listing Rule.

In addition to the oversight role of our Compensation Committee for questions of management compensation including by way

of equity, under French law any option or restricted share plans or other share capital increases, whether for the benefit of senior

management or employees, may only be adopted by the Board of Directors pursuant to and within the limits of a shareholder

resolution approving the related capital increase and delegating to the Board the authority to implement such operations. While

NASDAQ rules require shareholder approval when a plan or other equity compensation arrangement is established or materially

amended, under French law our shareholders must decide any issuance of equity, as a general matter. We intend to follow our

French home country practice and ask our shareholders to delegate their authority to issue incentive equity and define the final

176 SANOFI FORM 20-F 2025

PART II
Item 16G. Corporate Governance

terms of any equity compensation plan or arrangements to our Board of Directors. We may, from time to time, ask for our

shareholders’ subsequent approval on an equity compensation arrangement in order to obtain advantageous tax treatment or

otherwise. In addition, under French law, our Board of Directors must obtain the prior approval of our shareholders before

establishing or amending a plan or arrangement that would exceed the limits of the granted delegation.

As described above, a number of issues, which could be resolved directly by a board or its committees in the United States ,

require the additional protection of direct shareholder consultation in France.

Because we are a “foreign private issuer” as described above, our Chief Executive Officer and our Chief Financial Officer issue

the certifications required by Section 302 and Section 906 of the Sarbanes-Oxley Act of 2002 on an annual basis (with the filing

of our annual report) rather than on a quarterly basis as would be the case of a US corporation filing quarterly reports on

Form 10- Q.

French corporate law provides that the Board of Directors must vote to approve a broadly defined range of transactions that

could potentially create conflicts of interest between Sanofi on the one hand and its directors and Chief Executive Officer on

the other hand, which are then presented to shareholders for approval at the next annual meeting. This legal safeguard

operates in place of certain provisions of the NASDAQ listing rules.

Sanofi is governed by the French Commercial Code, which provides that an ordinary general meeting of the shareholders may

validly deliberate when first convened if the shareholders present or represented hold at least one-fifth of the voting shares.

If it is reconvened, no quorum is required. The French Commercial Code further provides that the shareholders at an

extraordinary general meeting may validly deliberate when first convened only if the shareholders present or represented hold

at least one-quarter of the voting shares and, if reconvened, one-fifth of the voting shares. Therefore, Sanofi will not follow

NASDAQ Listing Rule 5620(c), which provides that the minimum quorum requirement for a meeting of shareholders is 33 1 ⁄ 3 % of

the outstanding common voting shares of the company. In accordance with the provisions of the French Commercial Code, the

required majority for the adoption of a decision is a simple majority (for an ordinary general meeting of the shareholders) or a

two-thirds majority (for an extraordinary general meeting) of the votes cast by the shareholders present or represented.

The Company has, pursuant to Rule 10D-1 under the Exchange Act, adopted a recovery policy for compensation erroneously

paid to “executive officers” (as defined in Rule 10D-1(d) under the Exchange Act) based in whole or in part on any financial

reporting measures pursuant to the applicable NASDAQ listing rules, Rule 10D-1 under the Exchange Act and applicable

interpretive guidance. For more information concerning our recovery policy for compensation erroneously paid to “executive

officers”, see also “Item 6. Directors, Senior Management and Employees – B. Compensation”. Our recovery policy for

compensation erroneously paid to “executive officers” is i ncorporated by reference to Exhibit 97 of the Company’s Annual

Report on Form 20-F for the year ended December 31, 2023.

ITEM 16K. Cybersecurity

Item 16K. Cybersecurity

Risk Management and Strategy

Sanofi has implemented a cybersecurity strategy i nvolving various dedicated personnel and resources aimed at preventing,

detecting and responding to cyberattacks, as well as being able to recover promptly in the event of material impact following a

cyberattack. Additionally, Sanofi has set up various cybersecurity proces ses applicable to subsidiaries within the Sanofi group.

Sanofi regularly updates its cybersecurity processes to address cybersecurity trends and threats. Cybersecurity processes have

been established to address material cybersecurity risks, including in connection with the following areas:

• information technology and solution usage;

• access control;

• patch management;

• security on specific environments (i.e. cloud, virtualization, SAP, automated systems, IoT, etc.);

• log management;

• network security;

• systems security standards;

• remote access;

• secure development of applications;

• cryptography;

• mobile devices;

• third-party management (including cybersecurity requirements in contracts); and

• incident management.

Sanofi utilizes security standards and frameworks (i.e. the NIST framework) and has established cross-functional risk control

capabilities to facilitate operational implementation aligned with its cybersecurity processes.

S anofi regularly analyzes its Internet-based services and performs regular penetration tests and attack simulations to assess the

protection and detection capabilities. The cybersecurity compliance status of computing assets connected to Sanofi’s network is

routinely consolidated for Sanofi's business units, including within manufacturing, and research and development sites. Monthly

dashboards are published and shared within Sanofi’s different business units and global functions. Sanofi implements corrective

measures and improvement actions in response to these processes. Data classification and protection tools are in place, such as

the implementation of a specific process and technology aimed at detecting and responding to abnormal data flows.

Sanofi has set up a cybersecurity operation center in charge of detecting and responding to cybersecurity threats and attacks, as

well as coordinating Sanofi-wide incident responses. Incident response trainings and simulations are run within Sanofi to seek to

be better prepared in case of a cybersecurity incident. In addition, Sanofi’s employees, who are the main users of Sanofi’s digital

assets, are regularly trained to face cybersecurity threats and attacks. In the event of a cyberattack, Sanofi has established a plan

that includes criteria triggering the notification process for material cybersecurity incidents,, including from the cybersecurity

operation center and the Chief Information Security Officer who can use the internal escalation channels to inform the

management and the Board of Directors and, as appropriate, the relevant regulatory bodies.

When dealing with third parties , our main commercial contracts include cybersecurity clauses aimed at ensuring such third

parties comply with Sanofi’s cybersecurity rules and requirements, especially when providing services to and processing data

from Sanofi. Additionally, Sanofi set up a vendor’s risk assessment program to evaluate the digital maturity of a vendor, which

covers their business continuity as well as their related internal regulations, such as data privacy. As part of their contractual

commitments major vendors and partners must report to Sanofi any cybersecurity incident that may have a significant impact for

Sanofi. A dedicated process has been implemented for third parties’ networks interconnected with Sanofi’s network, aimed at

limiting any propagation of a cyberattack to Sanofi’s digital assets.

Sanofi’s cybersecurity risk management processes are integrated into its overall risk management system through its enterprise

risk management process, which seeks to identify and address material risks to the organization. Each year, specific risk

committees identify the risks that affect Sanofi’s local businesses in each country it operates and Sanofi’s global functions, such

as Research and Development or Manufacturing and Supply.

Although Sanofi has put in place the cybersecurity processes described above, Sanofi remains exposed to cybersecurity attacks

and incidents and misuse or manipulation of any of its IT systems, which could have a material adverse effect on its business

strategy, results of operations or financial condition (see “ Item 3. Key Information — D. Risk factors — Risks relating to our

business — Breaches of data security, disruptions of information technology systems and cyber threats could result in financial,

legal, competitive, operational, business, or reputational harm ”).

178 SANOFI FORM 20-F 2025

PART II
Item 16K. Cybersecurity

Governance

Sanofi has appointed a Chief Information Security Officer who oversees Sanofi's information, cybersecurity, and technology

security. Our current Chief Information Security Officer has been working for Sanofi in this capacity since 2014 and has seventeen

years of experience in the cybersecurity industry, including eight years as the global head of cybersecurity at one of France’s

largest telecommunications companies. The Chief Information Security Officer is informed about and monitors the prevention,

detection, mitigation, and remediation of cybersecurity incidents through the cybersecurity operation center. He develops

appropriate plans to mitigate such risks. Such plans are validated by the Chief Digital Officer and shared with the Executive

Committee.

The Chief Information Security Officer belongs to the digital division and directly reports to the Chief Digital Officer, a member of

the Executive Committee. In addition, the Chief Information Security Officer is a permanent member of the group Risk

Committee and reports on the cybersecurity risk to such group Risk Committee, to the Audit Committee and to the Executive

Committee regularly. The reporting covers various matters, such as the outcomes of audits on Sanofi’s information systems, the

main incidents encountered over the preceding period, Sanofi’s digital transformation or the cybersecurity strategy and

framework for the coming years.

The group Risk Committee , comprised of the managers of Sanofi’s Global Business Units, consolidates the risks identified by the

specific committees and targets the high priority risks Sanofi is facing. The group Risk Committee then allocates each risk to the

relevant Executive Committee member (i.e. the cybersecurity risk is allocated to the Chief Digital Officer as the relevant member

of the Executive Committee, who manages the mitigation of such risk with the Chief Information Security Officer) and reports

regularly to the Audit Committee. Following this identification and allocation process, the group Risk Committee reports on a

quarterly basis to the Executive Committee on the progress of the mitigation plans.

The Audit Committee checks that the cybersecurity risks are well managed and reports on such management to the Board of

Directors. The Board of Directors is also informed of such risks, as well as other cybersecurity matters, through periodic reports

from the Chief Digital Officer, the Head of the group Risk Committee, or the Chief Information Security Officer.

Report of Independent Registered Public Accounting Firms

Report of Independent Registered Public Accounting Firms

To the Shareholders and the Board of Directors of Sanofi,

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Sanofi and its subsidiaries (together the “Company”) as of

December 31, 2025 , and 2024, the related consolidated income statements, and consolidated statements of comprehensive

income, of changes in equity and of cash flows for each of the two years in the period ended December 31, 2025 , including the

related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial

statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 , and 2024, and

the results of its operations and its cash flows for each of the two years in the period ended December 31, 2025 in conformity

with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board and in

conformity with IFRS as endorsed by the European Union .

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board ( United States )

(“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2025 , based on criteria established in

Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission

(2013 framework) and our report dated February 17, 2026 expressed an unqualified opinion thereon.

Basis for Opinion

The Company's management is responsible for these consolidated financial statements. Our responsibility is to express an

opinion on the Company’s consolidated financial statements based on our audits. We are public accounting firms registered with

the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws

and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the

audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement,

whether due to error or fraud.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement

of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.

Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated

financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by

management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits

provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial

statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or

disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or

complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated

financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate

opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Recoverable amount of other intangible assets - Acquired R&D, products, trademarks

and other rights

Description of the Matter

Other intangible assets composed of acquired R&D, products, trademarks and other rights amounted to €25,853 million at December 31, 2025 . Management recognized a net loss of €2,242 million relating to impairment charges and reversals for the year ended December 31, 2025 . As described in Notes B.6.1., D.4. and D.5. to the consolidated financial statements, other intangible assets not yet available for use are tested for impairment annually and whenever events or circumstances indicate that impairment might exist. Other intangible assets that generate separate cash flows and assets included in cash-generating units (CGUs) are assessed for impairment when events or changes in circumstances indicate that the asset or CGU may be impaired. Management estimates the recoverable amount of the asset and recognizes an impairment loss if the carrying amount of the asset exceeds its recoverable amount. The recoverable amount of the asset is the higher of its fair value less costs to sell or its value in use. Value in use is determined by management using estimated future cash flows generated by the asset or CGU which are discounted and prepared using the same methods as those used in the initial measurement of the assets and on the basis of medium-term strategic plans. Management cash flow projections include significant assumptions related to mid and long-term sales forecasts; perpetual growth or attrition rate, where applicable; discount rate; and probability of success of current research and development projects. The principal considerations for our determination that auditing the recoverable amount of other intangible assets is especially challenging, subjective, and required complex auditor judgment related to the significant judgments made by management when developing the significant assumptions utilized in the future cash flow projections as described above.

How We Addressed the Matter in Our Audit

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to management’s other intangible assets impairment assessment, including controls over the significant assumptions used in the impairment testing of the other intangible assets. These audit procedures also included, among others, testing management's process for developing the recoverable amount estimate of the other intangible assets, evaluating the appropriateness of the discounted cash flow model; testing the completeness, accuracy, and relevance of underlying data used in the model; and evaluating the significant assumptions used by management as described above. Evaluating management’s assumptions involved evaluating whether the assumptions used by management were reasonable by considering the current and past performance of other intangible assets in comparison to management’s previous forecasts and current trends, the consistency of certain assumptions with external market and industry data, and whether these assumptions were consistent with evidence obtained in other areas of the audit. We involved our professionals with specialized skills and knowledge to assist us notably in the assessment of the discount rate used by management.

Valuation of the provisions for rebates relating to Sanofi’s business in the United States –

Medicaid, Medicare and Managed Care

Description of the Matter

As described in Notes B.13.1. and D.23. to the consolidated financial statements, products sold in the United States include estimates of discounts and rebates incentives (hereinafter the “Rebates”) that are recognized as a reduction of gross sales in the period in which the underlying sales are recognized. The most significant rebate liabilities relate to Medicaid, Medicare and Managed Care programs which amounted to €1,197 million, €1,402 million and €1,727 million, respectively, at December 31, 2025 . The Rebates estimated by management are based on the nature and patient profile of the underlying product; the applicable regulations or the specific terms and conditions of contracts with governmental authorities, wholesalers, payers and other customers; historical data relating to similar contracts; past experience and sales growth trends for the same or similar products; actual inventory levels in distribution channels, monitored by Sanofi using internal sales data and externally provided data; market trends including competition, pricing and demand. The principal considerations for our determination that auditing the provisions for Rebates relating to the Company’s business in the United States is especially challenging and required complex auditor judgment related to the significant judgment by management due to significant measurement uncertainty involved in developing these provisions. These provisions are estimated based on multiple factors as described above.

How We Addressed the Matter in Our Audit

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to management’s estimates of the provisions for Rebates relating to the Company’s business in the United States, including controls over the assumptions used to estimate these Rebates. These procedures also included, among others, developing an independent estimate of the provisions for Rebates by utilizing third party data on inventory levels in distribution channels, volume, changes to price, the terms of the specific rebate programs, and the historical trend of actual rebate claims paid. Additionally, these procedures included testing actual rebate claims paid and evaluating the contractual terms of the Company’s rebate agreements. The independent estimate was compared to the provisions recorded by the Company.

Provisions for product liability risks, litigation and other and contingent liabilities

Description of the Matter

Non-current provisions for product liability risks, litigation and other were recorded in an amount of €1,127 million at December 31, 2025 . As described in Notes B.12., D.19.3. and D.22. to the consolidated financial statements, the Company records such provisions when an outflow of resources is probable and the amount of the outflow can be reliably estimated. The Company also discloses the contingent liabilities in circumstances where management is unable to make a reasonable estimate of the expected financial effect that will result from ultimate resolution of the proceeding, or a cash outflow is not probable. The pharmaceutical industry is highly regulated, which increases the inherent risk of litigation and arbitration. The Company is involved in litigation, arbitration and other legal proceedings. These proceedings are typically related to litigation concerning product liability claims, intellectual property rights, competition law and trade practices, as well as claims under warranties or indemnification arrangements relating to business divestments. The issues raised by these claims are highly complex and subject to substantial uncertainties; therefore, the probability of loss and an estimation of damages are difficult to ascertain. The principal considerations for our determination that auditing the provision for product liability risks, litigation and other, and auditing the contingent liabilities is especially challenging, subjective and required complex auditor judgment resulted from the determination that the measurement of the provisions can involve a series of complex judgments about future events and can rely heavily on estimates and assumptions by management. There is inherent uncertainty related to these cases and in estimating the likelihood and outcome of the cases.

How We Addressed the Matter in Our Audit

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to management’s evaluation of the provisions for product liability risks, litigation and other, including controls over determining whether a loss is probable and whether the amount of loss can be reasonably estimated, as well as the need for and the level of financial statement disclosures. These procedures also included, among others, obtaining and evaluating the letters of audit inquiry with internal and external legal counsels, evaluating management’s assessment regarding whether an unfavorable outcome is reasonably possible or probable and reasonably estimable through the evaluation of the legal letters and summaries of the proceedings and lawsuit correspondence. Professionals with specialized skill and knowledge were used to assist in evaluating certain legal letters from internal and external counsels. We also evaluated the Company’s disclosures for contingent liabilities.

Uncertain tax positions

Description of the Matter

As described in Notes B.22. and D.19.4. to the consolidated financial statements, the Company has recorded non-current liabilities pertaining to uncertain tax positions of €2,081 million at December 31, 2025 . The Company operates in multiple tax jurisdictions, carrying out potentially complex transactions that require management to make judgments and estimates as to the tax impact of those transactions. The positions adopted by the Company in tax matters are based on its interpretation of tax laws and regulations. Some of those positions may be subject to uncertainty. In such cases, the Company assesses the amount of the tax liability on the basis of the following assumptions: that its position will be examined by one or more tax authorities on the basis of all relevant information; that a technical assessment is carried out with reference to legislation, case law, regulations, and established practice; and that each position is assessed individually (or collectively where appropriate), with no offset or aggregation between positions. Those assumptions are assessed on the basis of facts and circumstances existing at the end of the reporting period. When an uncertain tax liability is regarded as probable, it is measured on the basis of the Company’s best estimate. The principal considerations for our determination that auditing uncertain tax positions is especially challenging, subjective and required complex auditor judgment related to the significant judgment by management when determining the liability for uncertain tax positions, including a high degree of estimation uncertainty of certain assumptions and interpretations of the tax laws and regulations underlying the positions.

How We Addressed the Matter in Our Audit

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to the identification and recognition of the liability for uncertain tax positions, management’s assessment and interpretation of tax laws and its evaluation of which tax positions may not be sustained upon audit and controls over measurement of the liability. These procedures also included, among others, testing the completeness and accuracy of the underlying data used in the calculation of the liability for uncertain tax positions and evaluating the assumptions used by management when determining its tax positions, the status of tax audits and investigations, and the potential impact of past claims. Our tax professionals assisted in evaluating management’s assessments by comparing the positions taken by management with tax regulations and past decisions from tax authorities and where applicable, evaluating opinions from the Company’s external tax advisors. We also evaluated the disclosures provided in the notes to the consolidated financial statements concerning uncertain tax positions.

31, 2023, the related consolidated income statements, and consolidated statements of comprehensive income, changes in

equity, and cash flows for the year ended December 31, 2023, and the related notes (collectively, "the consolidated financial

Opella described in Note D.1.1.1.

In our opinion, the consolidated financial statements, before the effects of the adjustments to retrospectively reflect the

classification as discontinued operations of Opella described in Note D.1.1.1, present fairly, in all material respects, the financial

Report of Independent Registered Public Accounting Firms

To the Shareholders and the Board of Directors of Sanofi,

Opinion on Internal Control over Financial Reporting

We have audited Sanofi and its subsidiaries’ (together the “Company”) internal control over financial reporting as of December 31,

2025 , based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring

Organizations of the Treadway Commission (2013 framework) (the “COSO criteria”). In our opinion, the Company maintained, in

all material respects, effective internal control over financial reporting as of December 31, 2025 , based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board ( United States )

(“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated

income statements, and consolidated statements of comprehensive income, of changes in equity and of cash flows for each of

the two years ended December 31, 2025 , including the related notes (collectively referred to as the “consolidated financial

statements”) and our report dated February 17, 2026 expressed an unqualified opinion thereon.

As indicated in Report of Management on Internal Control Over Financial Reporting appearing under Item 15, management’s

assessment and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of

Blueprint Medicines Corporation and its affiliates, which are included in the 2025 consolidated financial statements of the

Company and represented less than 1% of total assets as of December 31, 2025 and less than 1% of net sales for the year then

ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal

control over financial reporting of Blueprint Medicines Corporation and its affiliates.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting, and for its

assessment of the effectiveness of internal control over financial reporting, included in the Report of Management on Internal

Control Over Financial Reporting appearing under Item 15. Our responsibility is to express an opinion on the Company's internal

control over financial reporting based on our audit. We are public accounting firms registered with the PCAOB and are required

to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and

regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the

audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all

material respects.

Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial

reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of

internal control based on the assessed risk. Our audits also included performing such other procedures as we considered

necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the

reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally

accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that

(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions

of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation

of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the

company are being made only in accordance with authorizations of management and directors of the company; and (3) provide

reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s

assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,

projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate

because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Notes to the Consolidated Financial Statements

Introduction

Sanofi, together with its subsidiaries (collectively “Sanofi”, “the Group” or “the Company”), is a global healthcare leader engaged

in the research, development and marketing of therapeutic solutions focused on patient needs.

Sanofi is listed in Paris (Euronext: SAN) and New York (Nasdaq: SNY).

The consolidated financial statements for the year ended December 31, 2025 , and the notes thereto, were signed off by the

Sanofi Board of Directors on January 28, 2026 .

A/ Basis of preparation

A.1. International financial reporting standards (IFRS)

The consolidated financial statements cover the twelve-month periods ended December 31, 2025 , 2024 and 2023 .

In accordance with Regulation No. 1606/2002 of the European Parliament and Council of July 19, 2002 on the application

of international accounting standards, Sanofi has presented its consolidated financial statements in accordance with IFRS

since January 1, 2005. The term “IFRS” refers collectively to international accounting and financial reporting standards

(IASs and IFRSs) and to interpretations of the interpretations committees (SIC and IFRIC) with mandatory application as of

December 31, 2025 .

The consolidated financial statements of Sanofi as of December 31, 2025 have been prepared in compliance with IFRS

as issued by the International Accounting Standards Board (IASB) and with IFRS as endorsed by the EU as of December 31, 2025 .

IFRS as endorsed by the EU as of December 31, 2025 are available under the heading “IFRS Financial Statements” via the

following web link:

https://www.efrag.org/Endorsement

The consolidated financial statements have been prepared in accordance with the IFRS general principles of fair presentation,

going concern, accrual basis of accounting, consistency of presentation, materiality, and aggregation.

A.2. New standards, amendments and interpretations

A.2.1. New standards applicable from January 1, 2025

On August 15, 2023, the IASB issued "Lack of Exchangeability", an amendment to IAS 21 (The Effects of Changes in Foreign

Exchange Rates), relating to how to determine the exchange rate when a currency is not exchangeable. The amendment became

applicable on January 1, 2025, and did not have any material impact on the Sanofi financial statements.

On November 28, 2025, the IASB issued "Disclosures about Uncertainties in the Financial Statements", which includes illustrative

examples on how an entity applies the requirements in IFRS Accounting Standards to report the effects of uncertainties in its

financial statements. Those illustrative examples did not have any material impact on the Sanofi financial statements.

A.2.2. New pronouncements issued by the IASB and applicable from 2026 or later

This note describes standards, amendments and interpretations issued by the IASB that will have mandatory application in 2026

or subsequent years, and Sanofi’s position regarding future application.

On April 9, 2024, the IASB issued IFRS 18 (Presentation and Disclosure in Financial Statements), applicable from January 1, 2027.

Sanofi will not early adopt this new standard. The transition to IFRS 18 is in progress.

The assessment of the impacts of IFRS 18 transition on presentation and disclosure in Sanofi's consolidated financial statements is

ongoing. That assessment is addressing the requirement for subtotals in income statements; the classification of income and

expenses in defined categories such as operating, investing and financing; aggregation/disaggregation principles; disclosure of

management-defined performance measures; and the presentation of financial performance.

The future structure of the income statement will present operating expenses by function, with some line item adjustments based

on the "useful structured summary" principle under IFRS 18.

Management Performance Measures (MPMs) identified to date are "Business gross margin", "Business Operating Income" (BOI)

and "Business Net Income" (BNI); these are the non-IFRS measures that Sanofi currently uses in its financial communications, and

that are reconciled to its IFRS income statement in its management commentary ( see "Item 5. Operating and Financial Review

and Prospects" ).

From 2027 onwards, those MPMs will be defined and reconciled in the notes to the financial statements, with no significant

change expected in their definition.

SANOFI FORM 20-F 2025 F-11

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

On May 30, 2024, the IASB issued amendments to IFRS 9 and IFRS 7 relating to the classification and measurement of financial

instruments, applicable from January 1, 2026. Sanofi does not expect any material impact, and will not early adopt these

amendments.

On July 18, 2024, the IASB issued Volume 11 of its annual improvements to various standards, which are essentially in the nature of

clarifications, applicable from January 1, 2026 at the earliest. Sanofi does not expect any material impact, and will not early adopt

these amendments.

On December 18, 2024, the IASB issued "Contracts referencing nature-dependent electricity", amendments to IFRS 9 and IFRS 7,

applicable from January 1, 2026. The amendments clarify the application of the ‘own use’ exemption to Power Purchase

Agreements (PPAs) with physical delivery of renewable energy, and modify the hedge accounting requirements for contracts

without physical delivery (VPPAs). Sanofi does not expect any material impact and does not intend to early adopt these

amendments. Renewable energy purchase contracts entered into by Sanofi as of December 31, 2024 are described in note D.21.

Sanofi had not entered into any significant new long-term renewable energy purchase contracts as of December 31, 2025.

On November 13, 2025, the IASB issued "The Effects of Changes in Foreign Exchange Rates: Translation to a Hyperinflationary

Presentation Currency", amendments to IAS 21 that are applicable from January 1, 2027 (subject to endorsement by the EU).

Sanofi does not expect any material impact and will not early adopt these amendments.

A.3. Use of estimates and judgments

The preparation of financial statements requires management to make reasonable estimates and assumptions based on

information available at the date of the finalization of the financial statements. Those estimates and assumptions may affect the

reported amounts of assets, liabilities, revenues and expenses in the financial statements, and disclosures of contingent assets

and contingent liabilities as of the date of the review of the financial statements. Examples of estimates and assumptions include:

• amounts deducted from sales for projected sales returns, chargeback incentives, rebates and price reductions (see Notes B.13.

and D.23.);

• impairment of property, plant and equipment and intangible assets (see Notes B.6. and D.5.);

• the valuation of goodwill and the valuation and estimated useful life of acquired intangible assets ( see Notes B.3.2., B.4., D.4.

and D.5.);

• the amount of liabilities or provisions for restructuring, litigation, tax risks relating to corporate income taxes, and

environmental risks (see Notes B.12., B.19., B.20., D.19. and D.22.).

Actual results could differ from these estimates.

A.4. Hyperinflation

In 2025 , Sanofi continued to account for subsidiaries based in Venezuela using the full consolidation method, on the basis that

the criteria for control as specified in IFRS 10 (Consolidated Financial Statements) are still met. The contribution of the

Venezuelan subsidiaries to the consolidated financial statements is immaterial.

In Argentina, the cumulative rate of inflation over the last three years is in excess of 100 % , based on a combination of indices used

to measure inflation in that country. Consequently, Sanofi has since July 1, 2018 treated Argentina as a hyperinflationary economy

and has applied IAS 29. The impact of the resulting restatements is immaterial at Sanofi group level.

In Turkey, the cumulative rate of inflation over the last three years is in excess of 100 % based on a combination of indices used to

measure inflation in that country. Consequently, Sanofi has since January 1, 2022 treated Turkey as a hyperinflationary economy

and has applied IAS 29. The impact of the resulting restatements is immaterial at Sanofi group level.

B/ Summary of significant accounting policies

B.1. Basis of consolidation

In accordance with IFRS 10 (Consolidated Financial Statements), the consolidated financial statements of Sanofi include the

financial statements of entities that Sanofi controls directly or indirectly, regardless of the level of the equity interest in those

entities. An entity is controlled when Sanofi has power over the entity, exposure or rights to variable returns from its involvement

with the entity, and the ability to affect those returns through its power over the entity. In determining whether control exists,

potential voting rights must be taken into account if those rights are substantive, in other words they can be exercised on a

timely basis when decisions about the relevant activities of the entity are to be taken.

Entities consolidated by Sanofi are referred to as “subsidiaries”. Entities that Sanofi controls by means other than voting rights are

referred to as “consolidated structured entities”.

In accordance with IFRS 11 (Joint Arrangements), Sanofi classifies its joint arrangements (i.e. arrangements in which Sanofi

exercises joint control with one or more other parties) either as a joint operation (in which case, Sanofi recognizes the assets and

liabilities of the operation in proportion to its rights and obligations relating to those assets and liabilities) or as a joint venture.

F-12 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Sanofi exercises joint control over a joint arrangement when decisions relating to the relevant activities of the arrangement

require the unanimous consent of Sanofi and the other parties with whom control is shared.

Sanofi exercises significant influence over an entity when it has the power to participate in the financial and operating policy

decisions of that entity, but does not have the power to exercise control or joint control over those policies.

In accordance with IAS 28 (Investments in Associates and Joint Ventures), the equity method is used to account for joint ventures

(i.e. entities over which Sanofi exercises joint control) and for associates (i.e. entities over which Sanofi exercises significant

influence).

Under the equity method, the investment is initially recognized at cost, and subsequently adjusted to reflect changes in the net

assets of the associate or joint venture. IAS 28 does not specify the treatment to be adopted on first-time application of the

equity method to an investee following a step acquisition. Consequently, by reference to paragraph 10 of IAS 28, Sanofi has

opted to apply the cost method, whereby the carrying amount of the investment represents the sum of the historical cost

amounts for each step in the acquisition. As of the date on which the equity method is first applied, goodwill (which is included in

the carrying amount of the investment) is determined for each acquisition step. The same applies to subsequent increases in the

percentage interest in the equity-accounted investment.

When the criteria of IFRS 5 are met, Sanofi recognizes the equity interest within the balance sheet line item Assets held for sale .

The equity method is not applied to equity interests that are classified as held for sale assets.

Transactions between consolidated companies are eliminated, as are intragroup profits.

A list of the principal companies included in the consolidation in 2025 is presented in Note F.

B.2. Foreign currency translation

B.2.1. Accounting for foreign currency transactions in the financial statements of consolidated

entities

Non-current assets and inventories acquired in foreign currencies are translated into the functional currency using the exchange

rate prevailing at the acquisition date.

Monetary assets and liabilities denominated in foreign currencies are translated using the exchange rate prevailing at the end of

the reporting period. The gains and losses resulting from foreign currency translation are recorded in the income statement.

However, foreign exchange gains and losses arising from the translation of advances between consolidated subsidiaries for which

settlement is neither planned nor likely to occur in the foreseeable future are recognized in equity, in the line item Change in

currency translation differences.

B.2.2. Foreign currency translation of the financial statements of foreign entities

Sanofi presents its consolidated financial statements in euros (€). In accordance with IAS 21 (The Effects of Changes in Foreign

Exchange Rates), each subsidiary accounts for its transactions in the currency that is most representative of its economic

environment (the functional currency).

All assets and liabilities are translated into euros using the exchange rate of the subsidiary’s functional currency prevailing at the

end of the reporting period. Income statements are translated using a weighted average exchange rate for the period, except in

the case of foreign subsidiaries in a hyperinflationary economy. The resulting currency translation difference is recognized as a

separate component of equity in the consolidated statement of comprehensive income, and is recognized in the income

statement only when the subsidiary is sold or is wholly or partially liquidated.

B.3. Business combinations and transactions with non-controlling interests

B.3.1. Accounting for business combinations, transactions with non-controlling interests and loss

of control

Business combinations are accounted for in accordance with IFRS 3 (Business Combinations) and IFRS 10 (Consolidated Financial

Statements).

Business combinations are accounted for using the acquisition method. Under this method, the acquiree’s identifiable assets and

liabilities that satisfy the recognition criteria of IFRS 3 (Business Combinations) are measured initially at their fair values at the

date of acquisition, except for (i) non-current assets classified as held for sale (which are measured at fair value less costs to sell)

and (ii) assets and liabilities that fall within the scope of IAS 12 (Income Taxes) and IAS 19 (Employee Benefits). Restructuring

liabilities are recognized as a liability of the acquiree only if the acquiree has an obligation as of the acquisition date to carry out

the restructuring.

The principal accounting rules applicable to business combinations and transactions with non-controlling interests include:

• acquisition-related costs are recognized as an expense, as a component of Operating income ;

• contingent consideration is recognized in equity if the contingent payment is settled by delivery of a fixed number

of the acquirer’s equity instruments; otherwise, it is recognized i n liabilities related to business combinations.

SANOFI FORM 20-F 2025 F-13

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Contingent consideration is recognized irrespective of the probability of payment and measured at fair value at the acquisition

date . If the contingent consideration was originally recognized as a financial liability, subsequent adjustments to the liability

are recognized in profit or loss in the line item Fair value remeasurement of contingent consideration , unless the

adjustment is made within the 12 months following the acquisition date and relates to facts and circumstances existing as of

that date; and

• goodwill may be calculated on the basis of either (i) the entire fair value of the acquiree, or (ii) a share of the fair value of the

acquiree proportionate to the interest acquired. This option is elected for each acquisition individually.

Purchase price allocations are performed under the responsibility of management, with assistance from an independent valuer in

the case of major acquisitions. IFRS 3 does not specify an accounting treatment for contingent consideration arising from a

business combination made by an entity prior to the acquisition of control in that entity and carried as a liability in the acquired

entity’s balance sheet. The accounting treatment applied by Sanofi to such a liability is to measure it at fair value as of the

acquisition date and to report it in the line item Liabilities related to business combinations and to non-controlling interests,

with subsequent remeasurements recognized in profit or loss. This treatment is consistent with the accounting applied to

contingent consideration in the books of the acquirer.

Finally, management may where it deems fit elect to apply the optional test to identify concentration of fair value permitted

under IFRS 3 in order to determine whether a transaction is a business combination within the meaning of IFRS 3, or merely the

acquisition of an asset or of a group of similar assets.

B.3.2. Goodwill

The excess of the cost of an acquisition over Sanofi’s interest in the fair value of the identifiable assets and liabilities of the

acquiree is recognized as goodwill at the date of the business combination. Goodwill arising on the acquisition of subsidiaries is

shown in a separate balance sheet line item, whereas goodwill arising on the acquisition of investments accounted for using the

equity method is recorded in Investments accounted for using the equity method.

Goodwill arising on foreign operations is expressed in the functional currency of the country concerned and translated into euros

using the exchange rate prevailing at the end of the reporting period.

In accordance with IAS 36 (Impairment of Assets), goodwill is carried at cost less accumulated impairment (see Note B.6.).

Goodwill is tested for impairment annually and whenever events or circumstances indicate that impairment might exist. Such

events or circumstances include significant changes more likely than not to have an other-than-temporary impact on the

substance of the original investment.

B.4. Other intangible assets

Other intangible assets are initially measured at acquisition cost or production cost, including any directly attributable costs of

preparing the asset for its intended use, or (in the case of assets acquired in a business combination) at fair value as of the date of

the business combination. Intangible assets are amortized on a straight line basis over their useful lives.

The useful lives of other intangible assets are reviewed at the end of each reporting period. The effect of any adjustment to

useful lives is recognized prospectively as a change in accounting estimate.

Amortization of other intangible assets is recognized in the income statement within Amortization of intangible assets except

for amortization charged against (i) acquired or internally-developed software and (ii) other rights of an industrial or operational

nature, which is recognized in the relevant classification of expense by function.

Sanofi does not own any intangible assets with an indefinite useful life, other than goodwill.

Intangible assets (other than goodwill) are carried at cost less accumulated amortization and accumulated impairment, if any, in

accordance with IAS 36 (see Note B.6.).

B.4.1. Research and development not acquired in a business combination

Internally generated research and development

Under IAS 38, research expenses are recognized in profit or loss when incurred.

Internally generated development expenses are recognized as an intangible asset if, and only if, all the following six criteria can be

demonstrated: (a) the technical feasibility of completing the development project; (b) Sanofi’s intention to complete the project;

(c) Sanofi’s ability to use the project; (d) the probability that the project will generate future economic benefits; (e) the availability

of adequate technical, financial and other resources to complete the project; and (f) the ability to measure the development

expenditure reliably.

Due to the risks and uncertainties relating to regulatory approval and to the research and development process, the six criteria

for capitalization are usually considered not to have been met until the product has obtained marketing approval from the

regulatory authorities. Consequently, internally generated development expenses arising before marketing approval has been

obtained, mainly the cost of clinical studies, are generally expensed as incurred within Research and development expenses .

Some industrial development expenses (such as those incurred in developing a second-generation synthesis process) are

incurred after marketing approval has been obtained, in order to improve the industrial process for an active ingredient. To the

F-14 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

extent that the six IAS 38 criteria are considered as having been met, such expenses are recognized as an asset in the balance

sheet within Other intangible assets as incurred. Similarly, some clinical studies, for example those undertaken to obtain a

geographical extension for a molecule that has already obtained marketing approval in a major market, may in certain

circumstances meet the six capitalization criteria under IAS 38, in which case the related expenses are recognized as an asset in

the balance sheet within Other intangible assets .

Separately acquired research and development

Payments for separately acquired research and development are capitalized within Other intangible assets provided that they

meet the definition of an intangible asset: a resource that is (i) controlled by Sanofi, (ii) expected to provide future economic benefits

for Sanofi, and (iii) identifiable (i.e. it is either separable or arises from contractual or legal rights). Under paragraph 25 of IAS 38, the

first condition for capitalization (the probability that the expected future economic benefits from the asset will flow to the entity) is

considered to be satisfied for separately acquired research and development. Consequently, upfront and milestone payments to

third parties related to pharmaceutical products for which marketing approval has not yet been obtained are recognized as

intangible assets, and amortized on a straight line basis over their useful lives beginning when marketing approval is obtained.

Payments under research and development arrangements relating to access to technology or to databases, and payments made

to purchase generics dossiers, are also capitalized, and amortized over the useful life of the intangible asset.

Subcontracting arrangements, payments for research and development services, and continuous payments under research and

development collaborations which are unrelated to the outcome of that collaboration, are expensed over the service term.

B.4.2. Other intangible assets not acquired in a business combination

Licenses other than those related to pharmaceutical products and research projects, in particular software licenses, are

capitalized at acquisition cost, including any directly attributable cost of preparing the software for its intended use. Software

licenses are amortized on a straight line basis over their useful lives for Sanofi ( three to five years ).

Internally generated costs incurred to develop or upgrade software are capitalized if the IAS 38 recognition criteria are satisfied,

and amortized on a straight line basis over the useful life of the software from the date on which the software is ready for use.

B.4.3. Other intangible assets acquired in a business combination

Other intangible assets acquired in a business combination (in-process research and development, technology platforms, and

currently marketed products) that are reliably measurable are identified separately from goodwill, measured at fair value, and

capitalized within Other intangible assets in accordance with IFRS 3 (Business Combinations) and IAS 38 (Intangible Assets). The

related deferred tax liability is also recognized if a deductible or taxable temporary difference exists.

In-process research and development acquired in a business combination is amortized on a straight line basis over its useful life

from the date of receipt of marketing approval.

Rights to technology platforms and to products currently marketed by Sanofi are amortized on a straight line basis over their

useful lives, determined (in particular for marketed products) on the basis of cash flow forecasts which take into account the

patent protection period of the marketed product.

B.5. Property, plant and equipment owned and leased

B.5.1. Property, plant and equipment owned

Property, plant and equipment is initially measured and recognized at acquisition cost, including any directly attributable cost of

preparing the asset for its intended use, or (in the case of assets acquired in a business combination) at fair value as of the date of

the business combination. The component-based approach to accounting for property, plant and equipment is applied. Under

this approach, each component of an item of property, plant and equipment with a cost which is significant in relation to the total

cost of the item and which has a different useful life from the other components must be depreciated separately.

After initial measurement, property, plant and equipment is carried at cost less accumulated depreciation and impairment, except

for land which is carried at cost less impairment.

Subsequent costs are not recognized as assets unless (i) it is probable that future economic benefits associated with those costs

will flow to Sanofi and (ii) the costs can be measured reliably.

Borrowing costs attributable to the financing of items of property, plant and equipment, and incurred during the construction

period, are capitalized as part of the acquisition cost of the item.

Government grants relating to property, plant and equipment are deducted from the acquisition cost of the asset to which

they relate.

The depreciable amount of items of property, plant and equipment, net of any residual value, is depreciated on a straight line

basis over the useful life of the asset. The useful life of an asset is usually equivalent to its economic life.

SANOFI FORM 20-F 2025 F-15

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The customary useful lives of property, plant and equipment are as follows:

Buildings	15 to 40 years
Fixtures	10 to 20 years
Machinery and equipment	5 to 15 years
Other	3 to 15 years

Useful lives and residual values of property, plant and equipment are reviewed annually. The effect of any adjustment to useful

lives or residual values is recognized prospectively as a change in accounting estimate.

Depreciation of property, plant and equipment is recognized as an expense in the income statement, in the relevant classification

of expense by function.

B.5.2. Property, plant and equipment leased

Leases contracted by Sanofi have been accounted for in accordance with IFRS 16 (Leases). Sanofi recognizes a right-of-use asset

and a lease liability for all of its lease contracts, except for (i) leases relating to low-value assets and (ii) short-term leases

(12 months or less). Payments made in respect of leases not recognized on the balance sheet are recognized as an operating

expense on a straight line basis over the lease term.

On commencement of a lease, the liability for future lease payments is discounted at the incremental borrowing rate, which is a

risk-free rate adjusted to reflect the specific risk profile of each Sanofi entity. Because lease payments are spread over the lease

term, Sanofi applies a discount rate based on the duration of those payments.

The payments used to determine the liability for future lease payments exclude non-lease components, but include fixed

payments that Sanofi expects to make to the lessor over the estimated lease term.

After commencement of the lease, the liability for future lease payments is reduced by the amount of the lease payments made,

and increased to reflect interest on the liability. In the event of a reassessment or modification of future lease payments, the lease

liability is remeasured. The right-of-use asset – which is initially measured at cost including direct costs of the lessee,

prepayments made at or prior to the commencement date, less lease incentives received and restoration costs – is depreciated

on a straight line basis over the lease term, and tested for impairment as required.

Sanofi recognizes deferred taxes in respect of right-of-use assets and lease liabilities.

Leasehold improvements are depreciated over their economic life, which is capped at the lease term as determined

under IFRS 16.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.6. Impairment of property, plant and equipment, intangible assets, and investments

accounted for using the equity method

B.6.1. Impairment of property, plant and equipment and intangible assets

In accordance with IAS 36 (Impairment of Assets), assets that generate separate cash flows and assets included in

cash-generating units (CGUs) are assessed for impairment when events or changes in circumstances indicate that the asset or

CGU may be impaired. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent

of the cash inflows from other assets or groups of assets.

Under IAS 36, each CGU or group of CGUs to which goodwill is allocated must (i) represent the lowest level within the entity at

which the goodwill is monitored for internal management purposes, and (ii) not be larger than an operating segment determined

in accordance with IFRS 8 (Operating Segments), before application of the IFRS 8 aggregation criteria (see Note B.26.).

Quantitative and qualitative indications of impairment (primarily relating to the status of the research and development portfolio,

pharmacovigilance, patent litigation, and the launch of competing products) are reviewed at the end of each reporting period. If

there is any internal or external indication of impairment, Sanofi estimates the recoverable amount of the asset or CGU.

Other intangible assets not yet available for use (such as capitalized in-process research and development), and CGUs or groups

of CGUs that include goodwill, are tested for impairment annually whether or not there is any indication of impairment, and more

frequently if any event or circumstance indicates that they might be impaired. Such assets are not amortized.

When there is an internal or external indication of impairment, Sanofi estimates the recoverable amount of the asset and

recognizes an impairment loss if the carrying amount of the asset exceeds its recoverable amount. The recoverable amount of

the asset is the higher of its fair value less costs to sell or its value in use. To determine value in use, Sanofi uses estimates of future

cash flows generated by the asset or CGU, prepared using the same methods as those used in the initial measurement of the

asset or CGU on the basis of medium-term strategic plans.

In the case of goodwill, estimates of future cash flows are based on a five-year strategic plan, an extrapolation of the cash flows

over a further five-year period, and a terminal value. In the case of other intangible assets, the period used is based on the

economic life of the asset.

Estimated cash flows are discounted at long-term market interest rates that reflect the best estimate by Sanofi of the time value

of money, the risks specific to the asset or CGU, and economic conditions in the geographical regions in which the business

activity associated with the asset or CGU is located.

Certain assets and liabilities that are not directly attributable to a specific CGU are allocated between CGUs on a basis that is

reasonable, and consistent with the allocation of the corresponding goodwill.

Impairment losses arising on property, plant and equipment, software and certain rights, are recognized within the appropriate

income statement line item according to the origin of the impairment.

Impairment losses arising on other intangible assets (products, trademarks, technology platforms, acquired R&D) are recognized

within Impairment of intangible assets in the income statement.

B.6.2. Impairment of investments accounted for using the equity method

In accordance with IAS 28 (Investments in Associates and Joint Ventures), Sanofi determines whether investments accounted for

using the equity method may be impaired based on indicators such as default in contractual payments, significant financial

difficulties, probability of bankruptcy, or a prolonged or significant decline in quoted market price. If an investment is impaired,

the amount of the impairment loss is determined by applying IAS 36 (see Note B.6.1.) and recognized in Share of profit/(loss)

from investments accounted for using the equity method.

B.6.3. Reversals of impairment losses charged against property, plant and equipment,

intangible assets, and investments accounted for using the equity method

At the end of each reporting period, Sanofi assesses whether events or changes in circumstances indicate that an impairment

loss recognized in a prior period in respect of an asset (other than goodwill) or an investment accounted for using the equity

method can be reversed. If this is the case, and the recoverable amount as determined based on the revised estimates exceeds

the carrying amount of the asset, Sanofi reverses the impairment loss only to the extent of the carrying amount that would have

been determined had no impairment loss been recognized for the asset.

Reversals of impairment losses in respect of other intangible assets are recognized within the income statement line item

Impairment of intangible assets , while reversals of impairment losses in respect of investments accounted for using the equity

method are recognized within the income statement line item Share of profit/(loss) from investments accounted for using the

equity method . Impairment losses taken against goodwill are never reversed, unless the goodwill is part of the carrying amount

of an investment accounted for using the equity method.

SANOFI FORM 20-F 2025 F-17

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.7. Assets held for sale and liabilities related to assets held for sale and

discontinued operations

In accordance with IFRS 5 (Non-Current Assets Held for sale and Discontinued Operations), non-current assets and groups of

assets are classified as held for sale in the balance sheet if their carrying amount will be recovered principally through a sale

transaction rather than through continuing use. Within the meaning of IFRS 5, the term “sale” also includes exchanges for other

assets.

Non-current assets or asset groups held for sale must be available for immediate sale in their present condition, subject only to

terms that are usual and customary for sales of such assets, and a sale must be highly probable. Criteria used to determine

whether a sale is highly probable include:

• the appropriate level of management must be committed to a plan to sell;

• an active program to locate a buyer and complete the plan must have been initiated;

• the asset must be actively marketed for sale at a price that is reasonable in relation to its current fair value;

• completion of the sale should be foreseeable within the 12 months following the date of reclassification to Assets held for

sale ; and

• actions required to complete the plan should indicate that it is unlikely that significant changes to the plan will be made or that

the plan will be withdrawn.

Before initial reclassification of the non-current asset (or asset group) to Assets held for sale , the carrying amounts of the asset

(or of all the assets and liabilities in the asset group) must be measured in accordance with the applicable standards.

Subsequent to reclassification to Assets held for sale , the non-current asset (or asset group) is measured at the lower of carrying

amount or fair value less costs to sell, with any write-down recognized by means of an impairment loss. Once a non-current asset

has been reclassified as held for sale or exchange, it is no longer depreciated or amortized.

From the date of reclassification:

• property, plant and equipment, right-of-use assets and intangible assets are no longer subject to individual depreciation,

amortization or impairment; and

• the share of profits and losses from investments accounted for using the equity method is no longer recognized.

In a disposal of an equity interest leading to loss of control, all the assets and liabilities of the entity involved are classified as held

for sale assets or liabilities within the balance sheet line items Assets held for sale or Liabilities related to assets held for sale ,

provided that the disposal satisfies the IFRS 5 classification criteria.

The profit or loss generated by a held for sale asset group is reported in a separate line item in the income statement for the

current period and for the comparative periods presented, provided that the asset group:

• represents a separate major line of business or geographical area of operations; or

• is part of a single coordinated plan to dispose of a separate major line of business or geographical area of operations; or

• is a subsidiary acquired exclusively with a view to resale.

In accordance with IFRS 10, intragroup balances and transactions relating to held for sale entities are eliminated.

In the absence of any specific accounting treatment under IFRS 5, Sanofi has opted to eliminate transactions between

discontinued operations and continuing operations so as to reflect the impact of such transactions consistently with the way

they are presented in the income statement after effective loss of control.

Events or circumstances beyond Sanofi’s control may extend the period to complete the sale or exchange beyond one year

without precluding classification of the asset (or disposal group) in Assets held for sale provided that there is sufficient evidence

that Sanofi remains committed to the planned sale or exchange. Finally, in the event of changes to a plan of sale that requires an

asset no longer to be classified as held for sale, IFRS 5 specifies the following treatment:

• the assets and liabilities previously classified as held for sale are reclassified to the appropriate balance sheet line items, with

no restatement of comparative periods;

• each asset is measured at the lower of (a) its carrying amount before the asset was reclassified as held for sale, adjusted for

any depreciation, amortization or revaluation that would have been recognized if the asset had not been reclassified as held

for sale, or (b) its recoverable amount at the date of reclassification;

• the backlog of depreciation, amortization and impairment not recognized while non-current assets were classified as held for

sale must be reported in the same income statement line item that was used to report impairment losses arising on initial

reclassification of assets as held for sale and gains or losses arising on the sale of such assets. In the consolidated income

statement, those impacts are reported within the line item Other gains and losses, and litigation ;

• the net income of a business previously classified as discontinued or as held for sale or exchange and reported on a separate

line in the income statement must be reclassified and included in net income from continuing operations, for all periods

presented; and

• in addition, segment information relating to the income statement and the statement of cash flows (acquisitions of

non-current assets) must be disclosed in the notes to the financial statements in accordance with IFRS 8 (Operating

Segments), and must also be restated for all prior periods presented.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.8. Financial instruments

B.8.1. Non-derivative financial assets

In accordance with IFRS 9 (Financial Instruments) and IAS 32 (Financial Instruments: Presentation), Sanofi has adopted the

classification of non-derivative financial assets described below. The classification used depends on (i) the characteristics of the

contractual cash flows (i.e. whether they represent interest or principal) and (ii) the business model for managing the asset

applied at the time of initial recognition.

Financial assets at fair value through other comprehensive income

These mainly comprise:

• quoted and unquoted equity investments that Sanofi does not hold for trading purposes and that management has

designated at “fair value through other comprehensive income” on initial recognition. Gains and losses arising from changes in

fair value are recognized in equity within the statement of comprehensive income in the period in which they occur. When

such instruments are derecognized, the previously-recognized changes in fair value remain within Other comprehensive

income , as does the gain or loss on divestment. Dividends received are recognized in profit or loss for the period, within the

line item Financial income ; and

• debt instruments whose contractual cash flows represent payments of interest or repayments of principal, and which are

managed with a view to collecting cash flows and selling the asset. Gains and losses arising from changes in fair value are

recognized in equity within the statement of comprehensive income in the period in which they occur. When such assets are

derecognized, the cumulative gains and losses previously recognized in equity are reclassified to profit or loss for the period

within the line items Financial income or Financial expenses .

Financial assets at fair value through profit or loss

These mainly comprise:

• contingent consideration receivable already carried in the books of an acquired entity or granted in connection with a

business combination;

• instruments whose contractual cash flows represent payments of interest and repayments of principal, which are managed

with a view to selling the asset in the short term;

• instruments that management has designated at “fair value through profit or loss” on initial recognition; and

• quoted and unquoted equity investments: equity instruments that are not held for trading and which management did not

designate at “fair value through other comprehensive income” on initial recognition, and instruments that do not meet the

IFRS definition of “equity instruments”.

Gains and losses arising from changes in fair value are recognized in profit or loss within the line items Financial income or

Financial expenses . Dividends received are recognized in profit or loss for the period, within the line item Financial income .

Fair value of equity investments in unquoted entities

On initial recognition of an equity investment in an entity not quoted in an active market, the fair value of the investment is the

transaction price except in specific circumstances. This acquisition cost ceases to be a representative measure of the fair value of

an unquoted equity investment when Sanofi identifies significant changes in the investee, or in the environment in which it

operates. In such cases, an internal valuation is carried out, based mainly on growth forecasts or by reference to similar

transactions contracted with third parties.

Financial assets measured at amortized cost

Financial assets at amortized cost comprise instruments whose contractual cash flows represent payments of interest and

repayments of principal and which are managed with a view to collecting cash flows. The main assets in this category are loans

and receivables. They are presented within the line items Other non-current assets , Other current assets , Accounts receivable

and Cash and cash equivalents . Loans with a maturity of more than 12 months are presented in “Long-term loans and

advances” within Other non-current assets . These financial assets are measured at amortized cost using the effective interest

method.

Impairment of financial assets measured at amortized cost

The main assets involved are accounts receivable. Accounts receivable are initially recognized at the amount invoiced to the

customer. Impairment losses on trade accounts receivable are estimated using the expected credit loss method, in order to take

account of the risk of payment default throughout the lifetime of the receivables. The expected credit loss is estimated

collectively for all accounts receivable at each reporting date using an average expected loss rate, determined primarily on the

basis of historical credit loss rates. However, that average expected loss rate may be adjusted if there are indications of a likely

significant increase in credit risk. If a receivable is subject to a known credit risk, a specific impairment loss is recognized for that

receivable. The amount of expected losses is recognized in the balance sheet as a reduction in the gross amount of accounts

receivable. Impairment losses on accounts receivable are recognized within Selling and general expenses in the income

statement.

SANOFI FORM 20-F 2025 F-19

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.8.2. Derivative instruments

Derivative instruments that do not qualify for hedge accounting are initially and subsequently measured at fair value, with

changes in fair value recognized in the income statement in Other operating income or in Financial income or Financial

expenses , depending on the nature of the underlying economic item which is hedged.

Derivative instruments that qualify for hedge accounting are measured using the policies described in Note B.8.3. below.

IFRS 13 (Fair Value Measurement) requires counterparty credit risk to be taken into account when measuring the fair value of

financial instruments. That risk is estimated on the basis of observable, publicly-available statistical data.

Policy on offsetting

In order for a financial asset and a financial liability to be presented as a net amount in the balance sheet under IAS 32, there must

be:

(a) a legally enforceable right to offset; and

(b) the intention either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

B.8.3. Hedging

As part of its overall market risk management policy, Sanofi enters into various hedging transactions involving derivative or

non-derivative instruments; these may include forward contracts, currency swaps or options, interest rate swaps or options,

cross-currency swaps, and debt placings or issues.

Such financial instruments are designated as hedging instruments and recognized using the hedge accounting principles

of IFRS 9 when (a) there is formal designation and documentation of the hedging relationship, of how the effectiveness of the

hedging relationship will be assessed, and of the underlying market risk management objective and strategy; (b) the hedged item

and the hedging instrument are eligible for hedge accounting; and (c) there is an economic relationship between the hedged

item and the hedging instrument, defined on the basis of a hedge ratio that is consistent with the underlying market risk

management strategy, and the residual credit risk does not dominate the value changes that result from that economic

relationship.

Fair value hedge

A fair value hedge is a hedge of the exposure to changes in fair value of an asset, liability or firm commitment that is attributable

to one or more risk components and could affect profit or loss.

Changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk

components are generally recognized in the income statement, within Other operating income for hedges related to operating

activities, or within Financial income or Financial expenses for hedges related to investing or financing activities.

Cash flow hedge

A cash flow hedge is a hedge of the exposure to variability in cash flows from an asset, liability or highly probable forecast

transaction that is attributable to one or more risk components and could affect profit or loss.

Changes in fair value of the hedging instrument attributable to the effective portion of the hedge are recognized directly in

equity in the consolidated statement of comprehensive income. Changes in fair value attributable to the ineffective portion of

the hedge are recognized in the income statement within Other operating income for hedges related to operating activities, and

within Financial income or Financial expenses for hedges related to investing or financing activities.

Cumulative changes in fair value of the hedging instrument previously recognized in equity are reclassified to the income

statement when the hedged transaction affects profit or loss. Those reclassified gains and losses are recognized within Other

operating income for hedges related to operating activities, and within Financial income or Financial expenses for hedges

related to investing or financing activities.

When a forecast transaction results in the recognition of a non-financial asset or liability, cumulative changes in the fair value of

the hedging instrument previously recognized in equity are incorporated in the initial carrying amount of that asset or liability.

When the hedging instrument expires or is sold, terminated or exercised, the cumulative gain or loss previously recognized in

equity remains separately recognized in equity and is not reclassified to the income statement, or recognized as an adjustment to

the initial cost of the related non-financial asset or liability, until the forecast transaction occurs. However, if Sanofi no longer

expects the forecast transaction to occur, the cumulative gain or loss previously recognized in equity is recognized immediately

in profit or loss.

Hedge of a net investment in a foreign operation

In a hedge of a net investment in a foreign operation, changes in the fair value of the hedging instrument attributable to the

effective portion of the hedge are recognized directly in equity in the consolidated statement of comprehensive income.

Changes in fair value attributable to the ineffective portion of the hedge are recognized in the income statement within

Financial income or Financial expenses . When the investment in the foreign operation is sold, the changes in the fair value of

the hedging instrument previously recognized in equity are reclassified to the income statement within Financial income or

Financial expenses .

F-20 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Cost of hedging

As part of its market risk management policy, Sanofi may designate currency options or interest rate options as hedging

instruments, the effectiveness of which is measured on the basis of changes in intrinsic value. In such cases, the time value of the

option is treated as a hedging cost and accounted for as follows:

• if the option includes a component that is not aligned on the critical features of the hedged item, the corresponding change in

the time value is taken to profit or loss;

• otherwise, the change in the time value is taken to equity within the statement of comprehensive income, and then:

– if the hedged item is linked to a transaction that results in the recognition of a financial asset or liability, the change in the

time value is reclassified to profit or loss symmetrically with the hedged item, or

– if the hedged item is linked to a transaction that results in the recognition of a non-financial asset or liability, the change in

the time value is incorporated in the initial carrying amount of that asset or liability, or

– if the hedged item is linked to a period of time, the change in time value is reclassified to profit or loss on a straight line basis

over the life of the hedging relationship.

In the case of forward contracts and foreign exchange swaps, and of cross-currency swaps that qualify for hedge accounting on

the basis of changes in spot rates, Sanofi may elect for each transaction to use the option whereby the premium/discount or

foreign currency basis spread are treated in the same way as the time value of an option.

Discontinuation of hedge accounting

Hedge accounting is discontinued when the eligibility criteria are no longer met (in particular, when the hedging instrument

expires or is sold, terminated or exercised), or if there is a change in the market risk management objective of the hedging

relationship.

B.8.4. Non-derivative financial liabilities

Borrowings and debt

Bank borrowings and debt instruments are initially measured at fair value of the consideration received, net of directly

attributable transaction costs.

Subsequently, they are measured at amortized cost using the effective interest method. All costs related to the issuance of

borrowings or debt instruments, and all differences between the issue proceeds net of transaction costs and the value on

redemption, are recognized within Financial expenses in the income statement over the term of the debt using the effective

interest method.

Liabilities related to business combinations and to non-controlling interests

These line items record the fair value of (i) contingent consideration payable in connection with business combinations and

(ii) commitments to buy out equity holders of subsidiaries, including put options granted to non-controlling interests.

Adjustments to the fair value of commitments to buy out equity holders of subsidiaries, including put options granted to

non-controlling interests, are recognized in equity.

Other non-derivative financial liabilities

Other non-derivative financial liabilities include trade accounts payable, which are measured at fair value (which in most cases

equates to face value) on initial recognition, and subsequently at amortized cost.

B.8.5. Fair value of financial instruments

Under IFRS 13 (Fair Value Measurement) and IFRS 7 (Financial Instruments: Disclosures), fair value measurements must be

classified using a hierarchy based on the inputs used to measure the fair value of the instrument. This hierarchy has three levels:

a. level 1: quoted prices in active markets for identical assets or liabilities (without modification or repackaging);

b. level 2: quoted prices in active markets for similar assets and liabilities, or valuation techniques in which all important inputs are

derived from observable market data; and

c. level 3: valuation techniques in which not all important inputs are derived from observable market data.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.8.6. Derecognition of financial instruments

Financial assets are derecognized when the contractual rights to cash flows from the asset have ended or have been transferred

and when Sanofi has transferred substantially all the risks and rewards of ownership of the asset. If Sanofi has neither transferred

nor retained substantially all the risks and rewards of ownership of a financial asset, it is derecognized if Sanofi does not retain

control of the asset.

A financial liability is derecognized when Sanofi’s contractual obligations in respect of the liability are discharged, cancelled or

extinguished.

B.8.7. Risks relating to financial instruments

Market risks in respect of non-current financial assets, cash equivalents, derivative instruments and debt are described in the

discussions of risk factors presented in “Item 3. Key Information — D. Risk factors” and “Item 11. Quantitative and Qualitative

Disclosures about Market Risk” of Sanofi’s annual report on Form 20-F for 2025 .

Credit risk is the risk that customers may fail to pay their debts. For a description of credit risk, refer to “We are subject to the risk

of non-payment by our customers” within “Item 3. Key Information — D. Risk factors” and “Item 11. Quantitative and Qualitative

Disclosures about Market Risk” of Sanofi’s annual report on Form 20-F for 2025 .

B.9. Inventories

Inventories are measured at the lower of cost or net realizable value. Cost is calculated using the weighted average cost method

or the first-in, first-out method, depending on the nature of the inventory.

The cost of finished goods inventories includes costs of purchase, costs of conversion and other costs incurred in bringing the

inventories to their present location and condition.

Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and

the estimated costs necessary to make the sale.

During the launch phase of a new product, any inventories of that product are written down to zero pending regulatory approval,

other than in specific circumstances which make it possible to estimate that there is a high probability at the end of the reporting

period that the carrying amount of the inventories will be recoverable. The write-down is reversed once it becomes highly

probable that marketing approval will be obtained.

B.10. Cash and cash equivalents

Cash and cash equivalents as shown in the consolidated balance sheet and statement of cash flows comprise cash, plus liquid

short-term investments that are readily convertible into cash and are subject to an insignificant risk of changes in value in the

event of movements in interest rates.

B.11. Treasury shares

In accordance with IAS 32, Sanofi treasury shares are deducted from equity, irrespective of the purpose for which they are held.

No gain or loss is recognized in the income statement on the purchase, sale, impairment or cancellation of treasury shares.

B.12. Provisions for risks

In accordance with IAS 37 (Provisions, Contingent Liabilities and Contingent Assets), Sanofi records a provision when it has a

present obligation, whether legal or constructive, as a result of a past event; it is probable that an outflow of resources

embodying economic benefits will be required to settle the obligation; and a reliable estimate can be made of the amount of the

outflow of resources.

If the obligation is expected to be settled more than 12 months after the end of the reporting period, or has no definite settlement

date, the provision is recorded within Non-current provisions and other non-current liabilities .

Provisions relating to the insurance programs in which Sanofi’s captive insurance company participates are based on risk

exposure estimates calculated by management, with assistance from independent actuaries, using IBNR (Incurred But Not

Reported) techniques. Those techniques use past claims experience, within Sanofi and in the market, to estimate future trends in

the cost of claims.

Contingent liabilities are not recognized, but are disclosed in the notes to the financial statements unless the possibility of an

outflow of economic resources is remote.

Sanofi estimates provisions on the basis of events and circumstances related to present obligations at the end of the reporting

period and of past experience, and to the best of management’s knowledge at the date of preparation of the financial

statements.

Reimbursements offsetting the probable outflow of resources are recognized as assets only if it is virtually certain that they will

be received. Contingent assets are not recognized.

Restructuring provisions are recognized if Sanofi has a detailed, formal restructuring plan at the end of the reporting period and

has announced its intention to implement this plan to those affected by it.

SANOFI FORM 20-F 2025 F-23

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

No provisions are recorded for future operating losses.

Sanofi records non-current provisions for certain obligations, such as legal or constructive obligations, where an outflow of

resources is probable and the amount of the outflow can be reliably estimated.

In the case of environmental risks, including at sites where operations are ongoing, Sanofi recognizes a provision where there is a

violation of integrity in respect of human health or the environment resulting from past contamination at a site that requires

remediation. The amount of the provision is a best estimate of the future expenditures to be incurred on the remediation plan.

Where the effect of the time value of money is material, those provisions are measured at the present value of the expenditures

expected to be required to settle the obligation, calculated using a discount rate that reflects an estimate of the time value of

money and the risk specific to the obligation.

Increases in provisions to reflect the effects of the passage of time are recognized within Financial expenses .

B.13. Revenue recognition

B.13.1. Net sales

Revenue arising from the sale of goods is presented in the income statement within Net sales . Net sales comprise revenue from

sales of medicines, vaccines and active ingredients, net of sales returns, of customer incentives and discounts, and of certain

sales-based payments paid or payable to the healthcare authorities. Analysis of net sales are provided in Note D.34.1. “ Analysis of

net sales”.

In accordance with IFRS 15 (Revenue from Contracts with Customers), such revenue is recognized when Sanofi transfers control

over the product to the customer; control of an asset refers to the ability to direct the use of, and obtain substantially all of the

remaining benefits from that asset. For the vast majority of contracts, revenue is recognized when the product is physically

transferred, in accordance with the delivery and acceptance terms agreed with the customer.

For contracts entered into by Vaccines franchise, transfer of control is usually determined by reference to the terms of release

(immediate or deferred) and acceptance of batches of vaccine.

In the case of contracts with distributors, Sanofi does not recognize revenue when the product is physically transferred to the

distributor if the products are sold on consignment, or if the distributor acts as an agent . In such cases, revenue is recognized

when control is transferred to the end customer, and the distributor’s commission is presented within the line item Selling and

general expenses in the income statement.

The amount of revenue recognized reflects the various types of price reductions or rights of return offered by Sanofi to its

customers on certain products. Such price reductions and rights of return qualify as variable consideration under IFRS 15.

In particular, products sold in the United States are covered by various Government and State programs (such as Medicare and

Medicaid) under which products are sold at a discount. Rebates are granted to healthcare authorities, and under contractual

arrangements with certain customers. Some wholesalers are entitled to chargeback incentives based on the selling price to the

end customer, under specific contractual arrangements. Cash discounts may also be granted for prompt payment. Returns,

discounts, incentives and rebates, as described above, are recognized in the period in which the underlying sales are recognized

as a reduction of gross sales .

These amounts are calculated as follows:

• the amount of chargeback incentives is estimated on the basis of the relevant subsidiary’s standard sales terms and

conditions, and in certain cases on the basis of specific contractual arrangements with the customer;

• the amount of rebates based on attainment of sales targets is estimated and accrued as each of the underlying sales

transactions is recognized;

• the amount of price reductions under Government and State programs, largely in the United States , is estimated on the basis

of the specific terms of the relevant regulations or agreements, and accrued as each of the underlying sales transactions is

recognized; and

• the amount of sales returns is calculated on the basis of management’s best estimate of the amount of product that will

ultimately be returned by customers. In countries where product returns are permitted, Sanofi operates a returns policy that

allows the customer to return products within a certain period either side of the expiry date (usually 12 months after the expiry

date). The amount recognized for returns is estimated on the basis of past experience of sales returns. Sanofi also takes into

account factors such as levels of inventory in its various distribution channels, product expiry dates, information about

potential discontinuation of products, the entry of competing generics into the market, and the launch of over-the-counter

medicines. Most product return clauses relate solely to date-expired products, which cannot be resold and are destroyed.

Sanofi does not recognize a right of return asset in the balance sheet for contracts that allow for the return of time-expired

products, since those products have no value.

F-24 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The estimated amounts described above are recognized in the income statement within Net sales as a reduction of gross sales,

and within Other current liabilities in the balance sheet. They are subject to regular review and adjustment as appropriate based

on the most recent data available to management. Sanofi believes that it has the ability to measure each of the above amounts

reliably, using the following factors in developing its estimates:

• the nature and patient profile of the underlying product;

• the applicable regulations or the specific terms and conditions of contracts with governmental authorities, payers, wholesalers

and other customers;

• historical data relating to similar contracts, in the case of qualitative and quantitative rebates and chargeback incentives;

• past experience and sales growth trends for the same or similar products;

• actual inventory levels in distribution channels, monitored by Sanofi using internal sales data and externally provided data;

• the shelf life of Sanofi products; and

• market trends including competition, pricing and demand.

An analysis of provisions for discounts, rebates and sales returns is provided in Note D.23.

B.13.2. Other revenues

The line item Other revenues is used to recognize all revenue that falls within the scope of IFRS 15 but does not relate to sales of

Sanofi products.

It mainly comprises (i) royalties received from licensing intellectual property rights to third parties; (ii) VaxServe sales of products

sourced from third-party manufacturers; and (iii) revenue received under agreements for Sanofi to provide manufacturing

services to third parties.

Royalties received under licensing arrangements are recognized over the period during which the underlying sales are

recognized.

VaxServe is a vaccine- related entity whose operations include the distribution within the US of vaccines and other products

manufactured by third parties. VaxServe sales of products sourced from third-party manufacturers are presented within Other

revenues .

Other revenues is also used to recognize revenues generated from the manufacturing of Consumer Healthcare products on

behalf of Opella entities. Until April 30, 2025, Opella entities were within the scope of discontinued operations (see Note B.7.).

With effect from May 1, 2025, Opella entities are treated as related parties in accordance with IAS 24 (see Note D.6.).

In addition, Other revenues includes revenues associated with Consumer Healthcare operations not transferred on the effective

date of loss of control of Opella. These comprise primarily, but not exclusively, Consumer Healthcare activities that were not

transferred on the effective date of loss of control of Opella, primarily (i) hospital sales of Opella products in China, the transfer of

which will be finalized no earlier than 2028 after a transitional period required to complete the transfer plan agreed with Sanofi in

the context of public tendering arrangements; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to

hold the capital (Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in

connection with the separation, the parties reserving the right to discuss the transfer of that entity during the term of the

distribution agreement) ; and (iii) sales of the Gold Bond product range, which are continuing in the US through the retained

subsidiary Gold Bond LLC (holder of the associated worldwide property rights).

B.14. Cost of sales

Cost of sales consists primarily of the industrial cost of goods sold, royalties paid for in-licensing of intellectual property, and

distribution costs. The industrial cost of goods sold includes the cost of materials, depreciation of property, plant and equipment,

amortization of software, personnel costs, and other expenses attributable to production . This line also includes the purchase

price of manufactured pharmaceutical products sourced from Opella.

B.15. Research and development

Note B.4.1. “Research and development not acquired in a business combination” and Note B.4.3. “Other intangible assets

acquired in a business combination” describe the principles applied to the recognition of research and development costs.

Contributions or reimbursements received from alliance partners are recorded as a reduction of Research and development

expenses .

SANOFI FORM 20-F 2025 F-25

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.16. Other operating income and expenses

B.16.1. Other operating income

Other operating income includes the share of profits that Sanofi is entitled to receive from alliance partners in respect of

product marketing agreements. It also includes revenues generated under certain agreements, which may include partnership,

co-promotion arrangements and licenses not included in Other revenues .

This line item also includes realized and unrealized foreign exchange gains and losses on operating activities (see Note B.8.3.), and

operating gains on disposals not regarded as major disposals (see Note B.20.).

B.16.2. Other operating expenses

Other operating expenses mainly comprise the share of profits that alliance partners are entitled to receive from Sanofi under

product marketing agreements.

B.17. Amortization and impairment of intangible assets

B.17.1. Amortization of intangible assets

The expenses recorded in this line item comprise amortization charged against intangible assets (products, trademarks and

technology platforms, see Note D.4.) whose contribution to Sanofi’s commercial, industrial and development functions cannot be

separately identified.

Amortization of software, and of other rights of an industrial or operational nature, is recognized as an expense in the income

statement, in the relevant line items of expense by function.

B.17.2. Impairment of intangible assets

This line item records impairment losses taken against intangible assets (products, trademarks, technology platforms and

acquired research), and any reversals of such impairment losses.

B.18. Fair value remeasurement of contingent consideration

Changes in the fair value of contingent consideration that was (i) already carried in the books of an acquired entity, or (ii) granted

in connection with a business combination and initially recognized as a liability in accordance with IFRS 3, are reported in profit or

loss. Such adjustments are reported separately in the income statement, in the line item Fair value remeasurement of

contingent consideration .

This line item also includes changes in the fair value of contingent consideration receivable in connection with a divestment and

classified as a financial asset at fair value through profit or loss.

Finally, it includes the effect of the unwinding of discount, and of exchange rate movements where the asset or liability is

expressed in a currency other than the functional currency of the reporting entity.

B.19. Restructuring costs and similar items

Restructuring costs are expenses incurred in connection with the transformation or reorganization of Sanofi’s operations or support

functions. Such costs include collective redundancy plans, compensation to third parties for early termination of contracts, and

commitments made in connection with transformation or reorganization decisions. They also include accelerated depreciation

charges arising from site closures (including closures of leased sites), and losses on asset disposals resulting from such decisions.

In addition, this line item includes (i) expenses incurred in connection with programs implemented as part of the transformation

strategy announced in December 2019 and recently renewed in October 2023, and intended primarily to deliver a global

information systems solution, further supported by the implementation from 2021 of Sanofi’s new digital strategy; and

(ii) transaction, integration and separation costs in connection with material acquisitions or divestitures .

B.20. Other gains and losses, and litigation

The line item Other gains and losses, and litigation includes the impact of material transactions of an unusual nature or amount

which Sanofi believes it necessary to report separately in the income statement in order to improve the relevance of the financial

statements, such as:

• gains and losses on major disposals of property, plant and equipment, of intangible assets, of assets (or groups of assets and

liabilities) held for sale, or of a business within the meaning of IFRS 3, other than those considered to be restructuring costs;

• impairment losses and reversals of impairment losses on assets (or groups of assets and liabilities) held for sale, other than

those considered to be restructuring costs;

• gains on bargain purchases;

• costs relating to major litigation; and

• pre-tax separation costs associated with the process of divestment from operations in the event of a major divestment.

F-26 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.21. Financial expenses and income

B.21.1. Financial expenses

Financial expenses mainly comprise interest charges on Sanofi's debt financing; negative changes in the fair value of certain

financial instruments (where changes in fair value are recognized in profit or loss); realized and unrealized foreign exchange losses

on financing and investing activities; impairment losses on financial instruments; and any reversals of impairment losses on

financial instruments.

Financial expenses also include expenses arising from the unwinding of discount on long-term provisions, and the net interest

cost related to employee benefits. This line item does not include commercial cash discounts, which are deducted from net sales .

B.21.2. Financial income

Financial income includes interest and dividend income; positive changes in the fair value of certain financial instruments (where

changes in fair value are recognized in profit or loss); realized and unrealized foreign exchange gains on financing and investing

activities; and gains on disposals of financial assets at fair value through profit or loss.

B.22. Income tax expense

Income tax expense includes all current and deferred taxes of consolidated companies.

Sanofi accounts for deferred taxes in accordance with IAS 12 (Income Taxes), using the methods described below:

• deferred tax assets and liabilities are recognized on taxable and deductible temporary differences, and on tax loss

carry-forwards. Temporary differences are differences between the carrying amount of an asset or liability in the balance

sheet and its tax base;

• French business taxes include a value added based component: “CVAE” (Cotisation sur la Valeur Ajoutée des Entreprises) .

Given that CVAE is (i) calculated as the amount by which certain revenues exceed certain expenses and (ii) borne primarily by

companies that own intellectual property rights on income derived from those rights (royalties, and margin on sales to third

parties and to Sanofi entities), it is regarded as meeting the definition of income taxes specified in IAS 12, paragraph 2 (“taxes

which are based on taxable profits”);

• deferred tax assets and liabilities are calculated using the tax rate expected to apply in the period when the corresponding

temporary differences are expected to reverse, based on tax rates enacted or substantively enacted at the end of the

reporting period;

• deferred tax assets are recognized in respect of deductible temporary differences, tax losses available for carry-forward and

unused tax credits to the extent that future recovery is regarded as probable. The recoverability of deferred tax assets is

assessed on a case-by-case basis, taking into account the profit forecasts contained in Sanofi’s medium-term business plan;

• a deferred tax liability is recognized for temporary differences relating to interests in subsidiaries, associates and joint

ventures, except in cases where Sanofi is able to control the timing of the reversal of the temporary differences. This applies in

particular when Sanofi is able to control dividend policy and it is probable that the temporary differences will not reverse in the

foreseeable future;

• no deferred tax is recognized on eliminations of intragroup transfers of interests in subsidiaries, associates or joint ventures;

• each tax entity calculates its own net deferred tax position. All net deferred tax asset and liability positions are then

aggregated and shown in separate line items on the relevant side of the consolidated balance sheet. Deferred tax assets and

liabilities are offset only if (i) Sanofi has a legally enforceable right to offset current tax assets and current tax liabilities, and

(ii) the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation authority;

• deferred taxes are not discounted, except implicitly in the case of deferred taxes on assets and liabilities which are already

impacted by discounting. In addition, Sanofi has elected not to discount current taxes payable or receivable where the

amounts in question are payable or receivable in the long term; and

• withholding taxes on intragroup royalties and dividends, and on royalties and dividends collected from third parties, are

accounted for as current income taxes.

In accounting for business combinations, Sanofi complies with IFRS 3 as regards the recognition of deferred tax assets after the

initial accounting period. Consequently, any deferred tax assets recognized by the acquiree after the end of that period in

respect of temporary differences or tax loss carry-forwards existing at the acquisition date are recognized in profit or loss.

The positions adopted by Sanofi in tax matters are based on its interpretation of tax laws and regulations. Some of those positions

may be subject to uncertainty. In such cases, Sanofi assesses the amount of the tax liability on the basis of the following

assumptions: that its position will be examined by one or more tax authorities on the basis of all relevant information; that a technical

assessment is carried out with reference to legislation, case law, regulations, and established practice; and that each position is

assessed individually (or collectively where appropriate), with no offset or aggregation between positions. Those assumptions are

assessed on the basis of facts and circumstances existing at the end of the reporting period. When an uncertain tax liability is

regarded as probable, it is measured on the basis of Sanofi’s best estimate and recognized as a liability; uncertain tax assets are not

recognized. The amount of the liability includes any penalties and late payment interest. The line item Income tax expense includes

the effects of tax reassessments and tax disputes, and any penalties and late payment interest arising from such disputes that have

the characteristics of income taxes within the meaning of paragraph 2 of IAS 12 (“taxes which are based on taxable profits”). Tax

exposures relating to corporate income taxes are presented separately within Non-current income tax liabilities (see Note D.19.4.).

SANOFI FORM 20-F 2025 F-27

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

No deferred taxation is recognized on temporary differences that are liable to be subject to US global intangible low

taxed income (GILTI) provisions. The related tax expense is recognized in the year in which it is declared in the tax return to the

extent that it arises from the existence of non-US profits that exceed the theoretical return on investment specified in the

GILTI provisions and are taxed at a rate lower than the applicable US tax rate.

As a reminder, Sanofi has applied in its consolidated financial statements “International Tax Reform – Pillar Two Model Rules”, an

amendment to IAS 12 issued by the IASB on May 23, 2023, and has not recognized deferred tax on temporary differences related

to Pillar Two rules.

In accordance with IAS 1 (Presentation of Financial Statements), current income tax assets and liabilities are presented as

separate line items in the consolidated balance sheet.

B.23. Employee benefit obligations

Sanofi offers retirement benefits to employees and retirees. Such benefits are accounted for in accordance with IAS 19 (Employee

Benefits).

Benefits are provided in the form of either defined contribution plans or defined benefit plans. In the case of defined contribution

plans, the cost is recognized immediately in the period in which it is incurred, and equates to the amount of the contributions paid

by Sanofi. For defined benefit plans, Sanofi recognizes its obligations to pay pensions and similar benefits to employees as a liability,

based on an actuarial estimate of the rights vested or currently vesting in employees and retirees, using the projected unit credit

method. Estimates are performed at least once a year, and rely on financial assumptions (such as discount rates, the inflation rate

and the rate of salary increases) and demographic assumptions (such as life expectancy, retirement age and employee turnover).

Obligations relating to other post-employment benefits (healthcare and life insurance) offered by Sanofi companies to

employees are also recognized as a liability based on an actuarial estimate of the rights vested or currently vesting in employees

and retirees at the end of the reporting period.

Such liabilities are recognized net of the fair value of plan assets.

In the case of multi-employer defined benefit plans where plan assets cannot be allocated to each participating employer with

sufficient reliability, the plan is accounted for as a defined contribution plan, in accordance with paragraph 34 of IAS 19.

The benefit cost for the period consists primarily of current service cost, past service cost, net interest cost, gains or losses arising

from plan settlements not specified in the terms of the plan, and the impact of plan curtailments. Net interest cost for the period

is determined by applying the opening discount rate specified in IAS 19 to the net liability (i.e. the amount of the obligation, net of

plan assets) recognized in respect of defined benefit plans. Past service cost is recognized immediately in profit or loss in the

period in which it is incurred, regardless of whether or not the rights have vested at the time of adoption (in the case of a new

plan) or of amendment (in the case of an existing plan).

Actuarial gains and losses on defined benefit plans (pensions and other post-employment benefits), also referred to

as “Remeasurements of the net defined benefit liability (asset)” , arise as a result of changes in financial and demographic

assumptions, experience adjustments, and the difference between the actual return and the return on plan assets included in the

calculation of the net interest cost. The impacts of those remeasurements are recognized in Other comprehensive income , net

of deferred taxes; they are not subsequently reclassifiable to profit or loss.

B.24. Share-based payment

Share-based payment expense is recognized as a component of operating income, in the relevant classification of expense by

function. In measuring the expense, the level of attainment of any performance conditions is taken into account.

B.24.1. Stock option plans

Sanofi has granted a number of equity-settled share-based payment plans (stock option plans) to some of its employees. The

terms of those plans may make the award contingent on the attainment of performance criteria for some of the grantees.

In accordance with IFRS 2 (Share-Based Payment), services received from employees as consideration for stock options are

recognized as an expense in the income statement, with the opposite entry recognized in equity. The expense corresponds to the

fair value of the stock option plans, and is charged to income on a straight-line basis over the four -year vesting period of the plan.

The fair value of stock option plans is measured at the date of grant using the Black-Scholes valuation model, taking into account

the expected life of the options. The resulting expense also takes into account the expected cancellation rate of the options. The

expense is adjusted over the vesting period to reflect (i) actual cancellation rates resulting from option-holders ceasing to be

employed by Sanofi and (ii) attainment of non-market performance conditions.

B.24.2. Employee share ownership plans

Sanofi may offer its employees the opportunity to subscribe to reserved share issues at a discount to the reference market price. Shares

awarded to employees under such plans fall within the scope of IFRS 2. Consequently, an expense is recognized at the subscription

date, based on the value of the discount offered to employees, with the opposite entry recognized in equity.

F-28 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

B.24.3. Restricted share plans

Sanofi may award restricted share plans to certain of its employees. The terms of those plans may make the award contingent on

the attainment of performance criteria for some of the grantees.

In accordance with IFRS 2, an expense equivalent to the fair value of such plans is recognized in profit or loss on a straight line

basis over the vesting period of the plan, with the opposite entry recognized in equity. The vesting period is three years .

The fair value of restricted share plans is based on the quoted market price of Sanofi shares at the date of grant, adjusted for

expected dividends during the vesting period; it also takes account of any vesting conditions contingent on stock market

performance, measured using the Monte-Carlo valuation model. Other vesting conditions are taken into account in the estimate

of the number of shares awarded during the vesting period; that number is then definitively adjusted based on the actual number

of shares awarded on the vesting date.

B.25. Earnings per share

Basic earnings per share is calculated using the weighted average number of shares outstanding during the reporting period,

adjusted on a time-weighted basis from the acquisition date to reflect the number of own shares held by Sanofi. Diluted earnings

per share is calculated on the basis of the weighted average number of ordinary shares, computed using the treasury stock method.

This method assumes that (i) all outstanding dilutive options and warrants are exercised, and (ii) Sanofi acquires its own shares at

the quoted market price for an amount equivalent to the cash received as consideration for the exercise of the options or

warrants, plus the expense arising on unamortized stock options.

B.26. Segment information

In accordance with IFRS 8 (Operating Segments), the segment information reported by Sanofi is prepared on the basis of internal

management data provided to our Chief Executive Officer, who is the chief operating decision maker of Sanofi. The performance

of the segment is monitored individually using internal reports and indicators.

Information about operating segments in accordance with IFRS 8 is presented in Note D.35., “Segment information”.

C/ Principal alliances

C.1. Alliance arrangements with Regeneron Pharmaceuticals, Inc. (Regeneron)

Collaboration agreements on human therapeutic antibodies

In November 2007, Sanofi and Regeneron signed two agreements (amended in November 2009) relating to human therapeutic

antibodies: (i) the Discovery and Preclinical Development Agreement, and (ii) the License and Collaboration Agreement, relating

to clinical development and commercialization. Under the License and Collaboration Agreement, Sanofi had an option to develop

and commercialize antibodies discovered by Regeneron under the Discovery and Preclinical Development Agreement.

Discovery and development

Because Sanofi decided not to exercise its option to extend the Discovery and Preclinical Development Agreement, that

agreement expired on December 31, 2017.

As a result of Sanofi’s exercise of an option with respect to an antibody under the Discovery and Preclinical Development

Agreement, such antibody became a “Licensed Product” under the License and Collaboration Agreement, pursuant to which

Sanofi and Regeneron co-develop the antibody with Sanofi initially being wholly responsible for funding the development

program. On receipt of the first positive Phase 3 study results for any antibody being developed under the License and

Collaboration Agreement, the subsequent development costs for that antibody are split 80 % Sanofi, 20 % Regeneron. Amounts

received from Regeneron under the License and Collaboration Agreement are recognized by Sanofi as a reduction in the line

item Research and development expenses . Co-development with Regeneron of the antibodies Dupixent, Kevzara and

REGN3500 (SAR440340 - itepekimab) is ongoing under the License and Collaboration Agreement as of December 31, 2025.

Once a product begins to be commercialized, and provided that the share of quarterly results under the agreement represents a

profit, Sanofi is entitled to an additional portion of Regeneron’s profit-share (capped at 20 % of Regeneron’s share of quarterly

profits since April 1, 2022, and at 10 % until March 31, 2022) until Regeneron has paid 50 % of the cumulative development costs

incurred by the parties in the collaboration (see Note D.21.1.).

On the later of (i) 24 months before the scheduled launch date or (ii) the first positive Phase 3 study results, Sanofi and Regeneron

share the commercial expenses of the antibodies co-developed under the License and Collaboration Agreement.

SANOFI FORM 20-F 2025 F-29

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Commercialization

Sanofi is the lead party with respect to the commercialization of all co-developed antibodies, and Regeneron has certain option

rights to co-promote the antibodies. Regeneron has exercised its co-promotion rights in the US and in certain other countries.

Sanofi recognizes all sales of the antibodies. Profits and losses arising from commercial operations in the US are split 50 /50.

Outside the US, Sanofi is entitled to between 55 % and 65 % of profits depending on sales of the antibodies, and bears 55 % of any

losses. The share of profits and losses due to or from Regeneron under the agreement is recognized within the line items Other

operating income or Other operating expenses , which are components of Operating income .

In addition, Regeneron is entitled to receive payments contingent on the attainment of specified levels of aggregate sales on all

antibodies outside the US, on a rolling twelve-month basis. The opposite entry for that liability is capitalized within Other

intangible assets on the balance sheet. Two payments of $ 50 million each were made in 2022, following attainment first of

$ 2.0 billion and then of $ 2.5 billion in sales of all antibodies outside the US on a rolling twelve-month basis. The final milestone

payment of $ 50 million , payable to Regeneron in the event that $ 3.0 billion in sales on a rolling twelve-month basis is attained,

was made in 2023 .

Amendments to the collaboration agreements

In January 2018, Sanofi and Regeneron signed a set of amendments to their collaboration agreements, including an amendment

that allowed for the funding of additional programs on Dupixent and REGN3500 (SAR440340 – itepekimab) with an intended

focus on extending the current range of indications, finding new indications, and improving co-morbidity between multiple

pathologies.

Effective April 1, 2020, Sanofi and Regeneron signed a Cross License and Commercialization Agreement for Praluent, whereby

Sanofi obtained sole ex-US rights to Praluent, and Regeneron obtained sole US rights to Praluent along with a right to 5 %

royalties on Sanofi’s sales of Praluent outside the US. Each party is solely responsible for funding the development, manufacturing

and commercialization of Praluent in their respective territories. Although each party has sole responsibility for supplying Praluent

in its respective territory, Sanofi and Regeneron are parties to agreements to support manufacturing needs for each other. These

agreements were renewed with an effective date of April 2025 to maintain the supply of active ingredients from Regeneron to

Sanofi until March 2026, and the supply of finished goods from Sanofi to Regeneron until December 2028.

Effective September 30, 2021, Sanofi and Regeneron signed an amendment to their collaboration agreement in order to specify

allocations of responsibilities and associated resources between the two parties in connection with the co-promotion of Dupixent

in certain countries. The terms of the collaboration relating to REGN3500 (SAR440340 – itepekimab) are unchanged.

Effective July 1, 2022, Sanofi and Regeneron signed an amendment to their collaboration agreement in order to increase the

additional portion of Regeneron’s quarterly profit-share attributable to Sanofi from 10 % to 20 % with retroactive impact as of

April 1, 2022.

Immuno-oncology (IO) collaboration agreements

On July 1, 2015, Sanofi and Regeneron signed two agreements – the IO Discovery and Development Agreement and the IO

License and Collaboration Agreement (IO LCA) – relating to new antibody cancer treatments in the field of immuno-oncology.

The Amended IO Discovery Agreement, effective from December 31, 2018, was terminated through a Letter Amendment dated

March 16, 2021 in which Sanofi formalized its opt-out from the BCMAxCD3 and MUC16xCD3 programs.

LIBTAYO (cemiplimab)

Under the 2015 IO LCA as amended in January 2018, Sanofi and Regeneron committed funding of no more than $ 1,640 million ,

split on a 50 /50 basis ( $ 820 million per company), for the development of REGN2810 (cemiplimab, trademark Libtayo), a PD-1

inhibitor antibody. The funding was raised to $ 1,840 million by way of amendment effective on September 30, 2021. Regeneron

was responsible for the commercializatio n of Libtayo in the US, and Sanofi in all other territories. Sanofi has exercised its option to

co-promote Libtayo in the United States . In 2021, Regeneron exercised its option to co-promote Libtayo in certain other

countries.

In June 2022, Sanofi and Regeneron restructured their IO LCA. Under the terms of the Amended and Restated IO LCA,

Regeneron holds exclusive worldwide licensing rights to Libtayo with effect from July 1, 2022.

In July 2022, Sanofi received as consideration an upfront payment of $ 900 million ( € 856 million ), which was recognized within

Other operating income on the date of receipt. The same line item also includes a regulatory milestone payment of $ 100 million

( € 96 million ) following the FDA approval in November 2022 of Libtayo in combination with chemotherapy as a first line treatment

for NSCLC (non-small cell lung cancer). In addition, Sanofi is entitled to royalties of 11 % and to milestone payments ( € 116 million in

2023, € 111 million in 2022) linked to global net sales of Libtayo; those royalties are recognized within Other operating income in

line with the pattern of sales . All of the cash inflows relating to the above items ( € 138 million in 2025 , € 117 million in 2024,

€ 196 million in 2023 ) are presented within Net cash provided by/(used in) operating activities in the consolidated statement of

cash flows.

The amendment to the terms of the IO LCA resulted in Sanofi recognizing an accelerated amortization charge of € 226 million

in 2022 ; this was allocated to the Libtayo product rights included within the residual carrying amount of the intangible asset

recognized in July 2015 to reflect rights to an antibody targeting the immune checkpoint receptor PD-1 (programmed cell death

protein-1) under the Sanofi/Regeneron alliance.

F-30 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The transaction also included time-limited transitional services agreements with Regeneron, including manufacturing,

distribution (for which Sanofi acted as agent), and promotion. Those services were all ended in 2025.

C.2. Agreements on the commercialization of Beyfortus

(nirsevimab, previously MEDI8897) in the US

On March 1, 2017, Sanofi and AstraZeneca entered into an agreement to develop and commercialize a monoclonal antibody

(MEDI8897, nirsevimab) for the prevention of Respiratory Syncytial Virus (RSV) associated illness in newborns and infants.

Under the terms of the agreement, Sanofi made an upfront payment of € 120 million in March 2017, a development milestone

payment of € 30 million in the third quarter of 2019, a regulatory milestone payment of € 25 million associated with the approval of

Beyfortus (nirsevimab) by the EMA in Europe in November 2022, and a regulatory milestone payment of € 65 million associated

with the approval of Beyfortus (nirsevimab) by the US FDA in July 2023.

In addition, Sanofi could pay AstraZeneca up to € 375 million if sales objectives are met. Those amounts are recognized as a

component of the value of the intangible asset when payment becomes probable.

In 2024, two payments of € 25 million and of € 50 million were made to AstraZeneca further to contractual sales thresholds being

met. In 2025, an additional payment of € 100 million was made in relation to a contractual sales threshold achieved in the last

quarter of 2024. No other sales milestone was achieved in 2025.

The agreement also specifies that AstraZeneca is responsible for development and manufacturing, and Sanofi for

commercialization. Sanofi recognizes the sales and cost of sales (purchases of finished products from AstraZeneca) and shares

the Alliance’s commercial profits (i) 50 /50 in major territories and (ii) based on 25 % of net revenues in other territories. The share

of commercial profits and losses due to or from AstraZeneca is recognized as a component of operating income, within the line

items Other operating income or Other operating expenses . In addition, Sanofi and AstraZeneca share development costs ,

with Sanofi’s portion recognized within the income statement line item Research and development expenses .

On April 9, 2023, Sanofi and AstraZeneca simplified their contractual agreements for the development and commercialization of

Beyfortus (nirsevimab) in the US. Sanofi thereby obtained control of all commercial rights to Beyfortus (nirsevimab) in the US, and

ended the sharing of commercial profits between the two partners in that territory. In line with the terms of the revised

agreements and in accordance with IAS 38, Sanofi recognized an intangible asset of € 1.6 billion for the fair value of the additional

US rights. On the same date, AstraZeneca and Sobi ended their participation agreement, signed in 2018, which transferred the

economic rights for the US territory to Sobi.

Sanofi simultaneously entered into an agreement with Sobi relating to direct royalties on US net sales of Beyfortus (nirsevimab). In

line with the terms of that agreement, on April 9, 2023 Sanofi recognized a financial liability amounting to € 1.6 billion . That liability

is classified as a financial liability at amortized cost under IFRS 9. Other than royalty payments, subsequent movements in the

liability comprise (i) the unwinding of discount and (ii) changes in estimates of future cash outflows for royalty payments. Those

movements will be recognized in the income statement within Net financial income/(expenses) in accordance with paragraph

B.5.4.6 of IFRS 9.

As of December 31, 2025 the liability was remeasured by an amount of €( 93 ) million ( € 291 million as of December 31, 2024 and

€ 541 million as of December 31, 2023; the remeasurement in 2023 reflected the strong success of the US launch of Beyfortus,

which led to sales forecasts being revised upward from the initial estimate). The resulting adjustment was recognized within

Financial expenses .

For territories other than the US (except for China, which is now considered a “major market,” with profits/losses shared 50 /50

with AstraZeneca), the existing agreement between AstraZeneca and Sanofi continues to govern the principal terms of the

collaboration: Sanofi recognizes the sales and cost of sales and shares the Alliance’s commercial profits with AstraZeneca.

Beyfortus was approved in Europe in November 2022, in the US in July 2023, in China and Japan during the first quarter of 2024,

and in a number of other countries in 2025.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

D/ Presentation of the financial statements

D.1. Significant transactions

D.1.1. Significant transactions of 2025

D.1.1.1. Opella - Loss of control and equity interest in the associate OPAL JV Co

On April 30, 2025, Sanofi and CD&R closed the Opella transaction following the signature of the share purchase agreement (SPA)

on February 18, 2025. Sanofi retains a significant shareholding in Opella, through a 48.2 % equity interest in the associate OPAL JV

Co (based in Luxembourg), which indirectly holds 100 % of Opella. Bpifrance owns a 1.8 % equity interest, and is represented on

Opella’s Board of Directors.

Completion of the deal resulted in the loss of control of Opella by Sanofi and the derecognition of Opella’s assets and liabilities.

This resulted in a net gain of € 2.6 billion , reported within the line item Net income from discontinued operations in the

consolidated income statement. The proceed s from the divestment of Opella, determined on the basis of a € 16 billion enterprise

value, reflect the price of the Opella shares. That price may be subject to adjustment following the finalization of the Opella

completion accounts as of April 30, 2025, which is expected to occur in the first quarter of 2026 in accordance with the SPA.

As of the closing date of the transaction, the carrying amount of Opella’s assets and liabilities in the Sanofi consolidated balance

sheet was € 11.3 billion .

The gain took into account the following components: (i) a reclassification of unrealized foreign exchange losses amounting to

€ 0.5 billion associated with Opella operations, in accordance with IAS 21 (“The Effects of Changes in Foreign Exchange Rates”);

(ii) recognition of the retained 48.2% equity interest in the associate OPAL JV Co (over which Sanofi exercises significant

influence as defined in IAS 28 “Investments in Associates and Joint Ventures”), reported within the balance sheet line item

Investments accounted for using the equity method at an amount of € 3.2 billion (representing the fair value of the equity

interest at the date of initial recognition in accordance with IFRS 10 and included in the estimated share price, plus capitalized

transaction costs); and (iii) other items, mainly comprising compensation as agreed under the separation agreements.

The Opella transaction generated a net cash inflow of € 10.4 billion , presented within the line item Net cash inflow from the

Opella transaction in the statement of cash flows.

The Shareholders’ Agreement between Sanofi and CD&R provides for a lock-up period of three years from the closing date,

during which Sanofi is only permitted to carry out certain types of direct or indirect transfers of its securities in OPAL JV Co;

thereafter any transfer by Sanofi is subject to a right of first offer in favor of CD&R, together with customary tag‑along and

drag‑along rights.

As a reminder, on October 21, 2024, Sanofi and CD&R entered into exclusive negotiations for the transfer of a controlling interest

in Opella. As of December 31, 2024, completion of the transaction was considered highly probable. In accordance with the

classification and presentation requirements of IFRS 5 ( see Note B.7. ), all assets of Opella and all liabilities directly related to those

assets were classified from October 21, 2024 in the line items Assets held for sale and Liabilities related to assets held for sale ,

respectively, in the consolidated balance sheet ( see Notes D.8. and D.36. ) Opella (formerly known as Consumer Healthcare)

constituted an operating segment of Sanofi until October 21, 2024 (see Note D.35., "Segment Information"). Consequently,

Opella met the definition of a discontinued operation under IFRS 5 (see Note B.7. ), as a result of which the net income from that

business was presented separately within the line item Net income from discontinued operations in the consolidated income

statement. This presentation in a separate income statement line item applied to operations for the year ended December 31,

2024 and December 31, 2025, and on a consistent basis for the comparative period presented (2023). The cash flows arising from

operating, investing and financing activities of the Opella business were also presented in separate line items in the consolidated

statements of cash flows for the year ended December 31, 2024 and December 31, 2025 and for the comparative period

present ed (2023).

As regards the product liability claims described in Note D.22. "Legal and arbitral proceedings", and in particular the ongoing

litigation relating to Zantac in the US, the Separation Agreement, executed July 2024, specifies that Sanofi is to indemnify Opella,

without limitation as to amount, for all liabilities resulting from the marketing of any Zantac brand product containing ranitidine as

an active pharmaceutical ingredient, including product liability claims.

D.1.1.2. Acquisition of Dren-0201, Inc.

On May 27, 2025 , Sanofi announced the completion of the acquisition of 100% of Dren-0201, Inc., adding SAR448501 (formerly

DR-0201) to Sanofi’s immunology pipeline. DR-0201, now named SAR448501, has shown robust B-cell depletion in pre-clinical

and early clinical studies. This potential first-in-class targeted bispecific myeloid cell engager targets and engages specific

tissue-resident and trafficking myeloid cells to induce deep B-cell depletion via targeted phagocytosis. Recent pre-clinical and

early clinical study data in autoimmune diseases suggest that deep B-cell depletion has the potential to reset the adaptive

immune system, leading to sustained treatment-free remission in patients with refractory B-cell mediated autoimmune diseases

such as lupus, where significant unmet medical needs remain.

The transaction did not meet the criteria for a business combination under IFRS 3, and consequently was accounted for as an

acquisition of a group of assets.

F-32 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The acquisition price was € 536 million . Of that amount (plus acquisition-related costs), € 522 million was allocated to in-process

development in respect of SAR448501, and recognized within Other intangible assets in accordance with IAS 38. The difference

between that amount and the acquisition price corresponds to the other assets acquired and liabilities assumed in the

transaction.

In addition, potential future payments totalling € 1.2 billion contingent on attainment of certain development and launch

milestones have been recognized as off balance sheet commitments. These milestones will be added to the value of the

SAR448501 intangible asset if and when achieved.

The impact of this acquisition, as reflected within the line item Acquisitions of consolidated undertakings and investments

accounted for using the equity method in the consolidated statement of cash flows, is a net cash outflow of € 539 million .

D.1.1.3. Acqui sition of Vigil Neuroscience, Inc.

On May 22, 2025, Sanofi announced that it had entered into an agreement to acquire Vigil Neuroscience, Inc. (Vigil), a publicly

traded clinical-stage biotechnology company focused on developing novel therapies for neurodegenerative diseases. This

acquisition in neurology, one of Sanofi’s four strategic disease areas, enhances Sanofi’s early-stage pipeline and includes

VG-3927, which will be evaluated in a Phase 2 clinical study in Alzheimer’s disease. VG-3927 is an oral small molecule TREM2

agonist. Activating TREM2 is expected to enhance the neuroprotective function of microglia in Alzheimer’s disease.

Under the terms of a share purchase agreement (including the exclusive right of first negotiation for an exclusive license to

VG-3927 or for transfer of the rights to research, develop, manufacture, and commercialize VG-3927) entered into by Sanofi and

Vigil in June 2024 for an amount of $ 40 million , Sanofi already held an equity interest in Vigil, representing approximately 12 % of

Vigil’s share capital. That equity interest was remeasured through Other comprehensive income .

VGL101, Vigil’s second molecule program, was not acquired by Sanofi.

On August 5, 2025, Sanofi acquired all outstanding common shares of Vigil for $8.00 per share in cash at closing. Based on $ 8.00

per share, the total equity value of Vigil represents approximately $ 470 million (on a fully diluted basis).

In addition, Vigil’s shareholders received one non-transferable and non-tradable contractual contingent value right (CVR) per

Vigil share, entitling the holder to receive a deferred cash payment of $ 2.00 contingent upon the first commercial sales of

VG-3927. That contingent consideration was recognized in Liabilities related to business combinations and to

non-controlling interests as of December 31, 2025 (see Note D.18.); the nominal value of the contingent consideration is

$ 114 million .

The provisional purchase price allocation resulted in the recognition of goodwill amounting to € 208 million , as indicated below:

(€ million)	Value at acquisition date
Other intangible assets	119
Other current and non-current assets and liabilities	( 2 )
Cash and cash equivalents	29
Net deferred tax position	43
Net assets of Vigil	189
Goodwill	208
Equity interests in Vigil acquired in June 2024	( 37 )
Purchase price (a)	360

(a) Includes the CVRs, valued at € 6 million as of the acquisition date.

Other intangible assets represent the value of the VG-3927 IPR&D project.

Goodwill mainly represents the future profits expected from additional pipeline products targeting various neurodegenerative

diseases, strengthening Sanofi’s strategic presence in the neurology therapeutic area.

The goodwill arising on this acquisition is not tax deductible.

Vigil has no commercial operations.

Acquisition-related costs were immaterial.

The impact of this acquisition, as reflected within the line item Acquisitions of consolidated undertakings and investments

accounted for using the equity method in the consolidated statement of cash flows, is a net cash outflow of € 326 million .

D.1.1.4. Acquisition of Blueprint Medicines Corporation

On June 2, 2025, Sanofi and Blueprint Medicines Corporation (Blueprint), a US-based, publicly traded biopharmaceutical

company specializing in the rare immunological disease systemic mastocytosis (SM) and other KIT-driven diseases, entered into

an agreement under which Sanofi agreed to acquire Blueprint.

The acquisition included a rare immunology disease medicine, Ayvakit/Ayvakyt (avapritinib), approved in the US and the EU, and

a promising advanced and early-stage immunology pipeline. Blueprint’s established presence among allergists, dermatologists,

and immunologists is expected to enhance Sanofi’s growing immunology pipeline.

SANOFI FORM 20-F 2025 F-33

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Under the terms of the acquisition, Sanofi agreed to pay $ 129.00 per share in cash at closing, representing an equity value of

approximately $ 9.1 billion on a fully diluted basis. Blueprint shareholders also received one non-transferable contractual

contingent value right (CVR) per share, entitling the holder to receive two potential milestone payments of $2.00 and $4.00 per

share on the attainment of future development and regulatory milestones within the applicable milestone period, respectively, for

BLU-808. That contingent consideration was recognized in Liabilities related to business combinations and to

non-controlling interests as of December 31, 2025 (see Note D.18.); the nominal value of the contingent consideration is

$ 448 million .

The total of the transaction, including potential CVR payments, represents approximately $ 9.5 billion on a fully diluted basis

( € 8.2 billion ).

In July 2025, Sanofi obtained control of Blueprint after all tender offer and merger conditions had been met.

The provisional purchase price allocation resulted in the recognition of goodwill amounting to € 801 million , as indicated below:

(€ million)	Value at acquisition date
Other intangible assets	6,814
Inventories	1,168
Other non-current and current assets and liabilities	312
Cash and cash equivalents	69
Short-term debt	( 375 )
Net deferred tax position	( 1,133 )
Net assets of Blueprint	6,855
Goodwill	801
Purchase price (a)	7,656

(a) Includes the CVRs, valued at € 45 million as of the acquisition date.

The other intangible assets recognized mainly comprise (i) the marketed rare immunology disease medicine Ayvakit/Ayvakyt

(avapritinib) and (ii) elenestinib, a next-generation medicine for systemic mastocytosis currently in the development phase and

expected to be a successor to avapritinib .

A fair value remeasurement of € 1,129 million was recognized at the acquisition date on finished goods and work-in-process

inventories, to reflect the level of expected profit margin and the amount of inventory on hand; it is expected to be consumed

over a period of approximately 28 months

Goodwill mainly represents the capacity to draw on a specialized structure to refresh the existing product portfolio; the

competencies of Blueprint staff; the benefits derived from the creation of new growth platforms in rare medicine; and other

benefits from the combination of Blueprint and Sanofi.

The goodwill arising on this acquisition is not tax deduc tible.

Blueprint's contributions to the net sales and business operating income of the Biopharma segment (for a definition refer to Note

D.35. “Segment Information”) since the acquisition date amount to € 305 million and € 25 million , respectively. Over the same

period, Blueprint made a negative contribution of € 621 million to consolidated net income, including amortization of intangible

assets of € 255 million ; amortization and expenses arising from the impact of acquired inventories of € 126 million ; and

restructuring costs and similar items of € 309 million .

During the year ended December 31, 20 25 , Blueprint generated net sales of € 641 million on a twelve-month basis.

Acquisition-related costs recognized in profit or loss for the period amounted to € 25 million .

The impact of this acquisition, as reflected within the line item Acquisitions of consolidated undertakings and investments

accounted for using the equity method in the consolidated statement of cash flows, is a net cash outflow of € 7,542 million .

D.1.1.5. Acquisition of Vicebio Ltd.

On December 4, 2025, Sanofi announced the completion of the acquisition of 100% of Vicebio Ltd (Vicebio), a privately held

biotechnology company headquartered in London, UK. The acquisition brings Sanofi an early-stage combination vaccine

candidate for respiratory syncytial virus (RSV) and human metapneumovirus (hMPV), both respiratory viruses, and expands

Sanofi's capabilities in vaccine design and development with Vicebio’s "Molecular Clamp" technology.

Sanofi applied the optional test to identify concentration of fair value under paragraph B7A of IFRS 3. The transaction was

accounted for as an acquisition of a group of assets, given that the principal asset ( the VXB-241 project, a bivalent vaccine

candidate targeting RSV and hMPV, currently in development ) concentrates substantially all of the fair value of the acquired set

of activities and assets.

The acquisition price was € 1,002 million . Of that amount (plus acquisition-related costs), € 977 million was allocated to VXB-241

and recognized within Other intangible assets in accordance with IAS 38. The difference between that amount and the

acquisition price corresponds to the other assets acquired and liabilities assumed in the transaction.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

In addition, potential future payments of up to $ 450 million contingent upon the attainment of development and regulatory

milestones have been recognized as off balance sheet commitments. These milestones will be added to the value of the

aforementioned intangible asset if and when attained.

The impact of this acquisition, as reflected within the line item Acquisitions of consolidated undertakings and investments

accounted for using the equity method in the consolidated statement of cash flows, is a net cash outflow of € 968 million .

D.1.1.6 Agreed transaction expected to be finalized in the first half of 2026

Acquisition of Dynavax Technologies Corporation

On December 24, 2025, Sanofi announced that it had entered into an agreement to acquire Dynavax Technologies Corporation.

(Dynavax), a publicly traded vaccines company with a marketed adult hepatitis B vaccine (HEPLISAV-B) and a differentiated

shingles vaccine candidate. The acquisition augments Sanofi’s presence in adult immunization by bringing together Dynavax’s

vaccines with Sanofi’s global scale, development capabilities and commercial reach.

Dynavax’s adult hepatitis B vaccine HEPLISAV-B is currently marketed in the US and is differentiated by its two-dose regimen

over one month, which enables high levels of seroprotection faster than other hepatitis B vaccines, which are given in three doses

over six months.

The acquisition also includes Dynavax’s shingles vaccine candidate (Z-1018), which is currently in Phase 1/2 clinical development

and additional vaccine pipeline projects.

Under the terms of the merger agreement, Sanofi will commence a cash tender offer to acquire all outstanding shares of Dynavax

for $ 15.50 per share in cash, reflecting a total equity value of approximately $ 2.2 billion .

The transaction has been unanimously approved by the Dynavax Board of Directors.

The acquisition is expected to close in the first quarter of 2026, subject to closing conditions.

A purchase price allocation will be performed at the acquisition date. Sanofi expects the main impacts to be the recognition of

intangible assets, in particular the HEPLISAV-B(R) vaccine commercialized product and Dynavax's shingles vaccine candidate

Z-1018.

D.1.2. Significant transactions of 2024

Acquisition of Inhibrx, Inc

On May 30, 2024 , Sanofi completed the acquisition of Inhibrx, Inc (Inhibrx), adding SAR447537 (formerly INBRX-101) to Sanofi’s

rare disease pipeline. SAR447537 is a human recombinant protein that holds the promise of allowing alpha-1 antitrypsin

deficiency (AATD) patients to achieve normalization of serum AAT levels with less frequent (monthly vs. weekly) dosing. AATD is

an inherited rare disease characterized by low levels of AAT protein, predominantly affecting the lungs with progressive tissue

deterioration. SAR447537 may help to reduce inflammation and prevent further deterioration of lung function in affected

individuals.

The transaction did not meet the criteria for a business combination under IFRS 3, and consequently was accounted for as an

acquisition of a group of assets.

The acquisition price was $ 2,035 million . Of that amount (plus acquisition-related costs), $ 1,885 million was allocated to

in-process development in respect of SAR447537 and recognized within Other intangible assets in accordance with IAS 38. The

difference between that amount and the acquisition price corresponds to the other assets acquired and liabilities assumed in the

transaction.

In addition, Sanofi awarded the former shareholders of Inhibrx an unquoted, non-negotiable Contingent Value Right (CVR)

certificate entitling them to a deferred cash payment of $ 5.00 per Inhibrx share, subject to attainment of a specified regulatory

milestone before June 30, 2027. The nominal value of that off balance sheet commitment is $ 300 million .

The impact of this acquisition, as reflected within the line item Acquisitions of consolidated undertakings and investments

accounted for using the equity method in the consolidated statement of cash flows, is a net cash outflow of $ 2,035 million .

Enjaymo divestment

On November 29, 2024, Sanofi entered into a definitive agreement with Recordati for the sale of Sanofi's global rights to Enjaymo

and the transfer of specific employees. Under this agreement, Sanofi received an upfront payment of $ 825 million and will be

eligible for milestone payments of up to $ 250 million based on sales.

This agreement led to the derecognition of assets relating to the Enjaymo activity, including goodwill of € 276 million . The gain

arising on the divestment was immaterial.

The impact of the divestment in the consolidated cash flow statement, as reflected in the line item Proceeds from disposals of

property, plant and equipment, intangible assets and other non-current assets, net of tax , is a pre-tax cash inflow of

€ 768 million .

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

D.1.3. Significant transactions of 2023

Acquisition of Provention Bio, Inc.

On March 13, 2023, Sanofi entered into a merger agreement with Provention Bio, Inc. (Provention), a US-based publicly traded

biopharmaceutical company developing therapies to prevent and intercept immune-mediated diseases including type 1 diabetes.

Under the terms of the agreement, Sanofi acquired the outstanding shares of Provention common stock for $ 25.00 per share in

an all-cash transaction valued at approximately $ 2.8 billion .

The acquisition of Provention was completed on April 27, 2023, with Sanofi holding all of the shares of Provention on expiration of

the tender offer.

Sanofi applied the optional test to identify concentration of fair value under paragraph B7A of IFRS 3. The transaction was

accounted for as an acquisition of a group of assets, given that the principal asset (teplizumab-mzwv, commercialized in the US

under the name Tzield) concentrates substantially all of the fair value of the acquired set of activities and assets.

Under the terms of a share purchase agreement entered into by Sanofi and Provention in February 2023, Sanofi already held an

equity interest in Provention, representing approximately 3 % of Provention’s share capital. On the date Sanofi obtained control of

Provention, that equity interest was remeasured at a price of $25.00 per share, representing a total amount of $ 68 million . The

impact of the remeasurement was recognized in Other comprehensive income .

The acquisition price for the shares not already held was $ 2,806 million . Out of the total price (including the fair value of the

shares already held), $ 2,810 million was allocated to Tzield and recognized within Other intangible assets . The difference

between that amount and the acquisition price corresponds to the other assets acquired and liabilities assumed as part of the

transaction, after taking account of the previously-held shares and acquisition-related costs.

The impact of this acquisition as reflected within the line item Acquisitions of consolidated undertakings and investments

accounted for using the equity method in the consolidated statement of cash flows is a net cash outflow of $ 2,722 million .

Acquisition of QRIB Intermediate Holdings, LLC

On July 28, 2023, Sanofi announced that it had acquired QRIB Intermediate Holdings, LLC (QRIB), the owner of Qunol, a

market-leading US-based health & wellness brand. The acquisition strengthened Opella's operations in the Vitamin, Mineral and

Supplements (VMS) category.

The acquisition of QRIB by Sanofi was completed on September 29, 2023, at a purchase price of $ 1,419 million .

The final purchase price allocation led to the recognition of goodwill of € 484 million , determined as follows:

(€ million)	Fair value at acquisition date
Other intangible assets	774
Other current and non-current assets and liabilities	80
Cash and cash equivalents	8
Deferred taxes, net	( 3 )
Net assets of QRIB Intermediate Holdings, LLC	859
Goodwill	484
Purchase price	1,343

The other acquired intangible assets identified consist of the Qunol brand.

Goodwill mainly represents the expected future profits attributable to the development of the VMS platform in the US as a result

of the integration of QRIB into the Sanofi group.

The entire amount of goodwill is deductible for tax purposes over a period of 15 years.

The imp act of this acquisition is reflected in Net cash provided by/(used in) investing activities of the discontinued Opella

business in the consolidated statement of cash flows, and represents a net cash outflow of $ 1,410 million .

Net assets related to this acquisition, including associated goodwill, are part of Opella's net assets and were therefore reclassified

to Assets held for sale and Liabilities related to assets held for sale as of December 31, 2024 (see Note D.36.).

D.2. Capital and financial risk management information

D.2.1. Capital management information

In order to maintain or adjust the capital structure, Sanofi can adjust the amount of dividends paid to shareholders, repurchase its

own shares, issue new shares, or issue securities giving access to its capital.

The following objectives are defined under the terms of Sanofi’s share repurchase programs:

• the implementation of any stock option plan giving entitlement to purchase shares in the Sanofi parent company (see Note D.15.);

• the allotment or sale of shares to employees under statutory profit sharing schemes and employee savings plans;

• the consideration-free allotment of shares (i.e. restricted share plans) (see Note D.15.);

• the cancellation of some or all of the repurchased shares (see Note D.15.);

• market-making in the secondary market by an investment services provider under a liquidity contract in compliance with the

ethical code recognized by the Autorité des marchés financiers (AMF);

• the delivery of shares on the exercise of rights attached to securities giving access to the capital by redemption, conversion,

exchange, presentation of a warrant or any other means;

• the delivery of shares (in exchange, as payment, or otherwise) in connection with mergers and acquisitions;

• the execution by an investment services provider of purchases, sales or transfers by any means, in particular via off-market

trading; or

• any other purpose that is or may in the future be authorized under the applicable laws and regulations.

Sanofi is not subject to any constraints on equity capital imposed by third parties.

Sanofi defines “Net debt” as (i) the sum of short-term debt, long-term debt and interest rate derivatives and currency derivatives

used to hedge debt, minus (ii) the sum of cash and cash equivalents and interest rate derivatives and currency derivatives used to

hedge cash and cash equivalents (see Note D.17.).

D.2.2. Financial risk management

Credit risk

Credit risk is the risk that customers (wholesalers, distributors, pharmacies, hospitals, clinics or government agencies) may fail to

pay their debts; for Sanofi, that risk is mainly concentrated on amounts receivable from wholesalers in the US. Sanofi manages

credit risk by vetting customers in order to set credit limits and risk levels, and asking for guarantees or insurance where

necessary; performing controls; and monitoring qualitative and quantitative indicators of accounts receivable balances, such as

the period of credit taken and overdue payments.

Sales generated by Sanofi with its biggest customers are disclosed in Note D.35.

(a) 2023 comparative figures were re-presented on a consistent basis from the date of the classification of Opella as a discontinued operation (2024).

D.5. Impairment of intangible assets and property, plant and equipment

Goodwill

When testing goodwill annually for impairment, the recoverable amount is determined for the Biopharma segment on the basis of

value in use, as derived from discounted estimates of the future cash flows in accordance with the policies described in

Note B.6.1.

The value in use of the Biopharma segment was determined by applying an after-tax discount rate to estimated future after-tax

cash flows. The after-tax rate used for impairment testing of the Biopharma segment is determined on the basis of Sanofi's

weighted average cost of capital (WACC) ; it was 7.25 % in 2025 .

The pre-tax discount rate applied to estimated pre-tax cash flows is calculated by iteration from the previously-determined value

in use; the rate for the Biopharma segment was 10.1 % .

The terminal value growth rate applied to future cash flows is determined so as to not exceed the projected long-term growth

rate for the industry. In 2025 , the perpetual growth rate applied to future cash flows for the Biopharma segment was zero .

Sanofi also applies assumptions on the probability of success of current research and development projects, and more generally

on its ability to renew the product portfolio in the longer term.

The assumptions used in testing goodwill for impairment are reviewed annually.

Value in use (determined as described above) is compared with the carrying amount, and this comparison is then subject to

sensitivity analyses by reference to key parameters including:

• changes in the discount rate;

• changes in the perpetual growth rate; and

• fluctuations in operating margin.

No impairment of the goodwill would need to be recognized in the event of a reasonably possible change to the assumptions

used in 2025 .

No impairment losses were recognized against goodwill in the years ended December 31, 2025 , 2024 or 2023 .

Other intangible assets

When there is evidence that an asset may have become impaired, the asset’s value in use is calculated by applying an after-tax

discount rate to the estimated future after-tax cash flows from that asset. Applying after-tax discount rates to after-tax cash

flows gives the same values in use as would be obtained by applying pre-tax discount rates to pre-tax cash flows.

The after-tax discount rates used for impairment testing of other intangible assets are obtained by adjusting Sanofi’s weighted

average cost of capital to reflect specific country and business risks. In 2025 , after-tax discount rates were in a range from 7.25 %

to 8.25 % .

In most instances, there are no market data that would enable fair value less costs to sell to be determined other than by means

of developing a similar estimate based on future cash flows. Consequently, recoverable amount is in substance equal to value in

use. The estimates used to determine value in use are sensitive to assumptions specific to the nature of the asset and to Sanofi's

activities. Apart from the discount rate, the principal assumptions used in 2025 were as follows:

• mid-term and long-term forecasts;

• perpetual growth or attrition rates, when applicable; and

• probability of success of current research and development projects.

The assumptions used in testing intangible assets for impairment are reviewed at least annually.

F-44 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

In 2025 , 2024 and 2023 , impairment testing of other intangible assets (excluding software) resulted in the recognition of net

impairment losses as shown below :

(€ million)	2025	2024	2023
Impairment of other intangible assets, net of reversals (excluding software)	2,241	265	932

Research and development projects and technology platforms (b)(c)(d)	2,185	415	896
Others	—	17	36

(a) For 2024, this comprises a reversal of € 167 million in connection with the disposal of Enjaymo.

(b) For 2025, this amount primarily comprises a € 1,663 million impairment loss recognized on tolebrutinib, a drug candidate in the registration phase

targeting multiple sclerosis, reflecting the reduced probability of approval arising from the negative PERSEUS Phase 3 study results in Primary

Progressive Multiple Sclerosis (PPMS) and the recent interactions with the FDA and EMA on Secondary Progressive Multiple Sclerosis (SPMS) . Other

impairment losses amounting to € 522 million were also recorded against various other research and development projects.

(c) For 2024, the net impairment loss of € 415 million comprises (i) impairment losses of € 640 million against various research and development projects

(including a € 239 million loss resulting from the decision taken in February 2025 to discontinue a Phase 3 clinical study investigating of a vaccine

candidate to prevent invasive E.coli disease) and (ii) an impairment reversal of € 225 million recognized in connection with the disposal of the ProXTen

technology platform.

(d) For 2023, this amount mainly comprises an impairment loss of € 833 million , reflecting the impact of the strategic decision to de-prioritize certain R&D

programs, in particular those related to the NK Cell and ProXTen technology platforms.

As required by IFRS 5, the other intangible assets of Opella were measured in accordance with IAS 36 immediately before their

reclassification as of December 31, 2024 as assets held for sale; this assessment did not result in any impairment of their carrying

amount being recognized.

Property, plant and equipment

Impairment losses taken against property, plant and equipment are disclosed in Note D.3.

Risks and opportunities related to climate change

Sanofi has identified specific plausible scenarios to assess climate risks and opportunities liable to impact its activities in the

medium and longer term.

These include:

• an Aggressive Mitigation scenario, based on global collaboration to start reducing emissions immediately to meet Paris

Agreement goals (limit temperature increase to 1.5°C above pre-industrial levels), generating risks related to transitioning to a

lower carbon economy and entailing extensive policy, legal, technology, and market changes to address mitigation and

adaptation requirements;

• a No Climate Action scenario (leading to global warming of 4°C above pre-industrial levels by 2100), with event-driven physical

risks resulting from climate change or longer term shifts in climate patterns leading to potential financial implications such as

direct damage to assets and indirect impacts from supply chain disruption; changes in water availability, and in the sourcing or

quality of resources; food security; and extreme temperature changes affecting premises, operations, supply chain, transport

needs, and employee safety; and

• a Most Likely scenario, encompassing fragmented regional efforts to start reducing emissions but not at a sufficient level to

meet Paris Agreement g oals (emissions continue to increase but at a slowed rate, leading to a 2.8°C temperature increase).

This scenario presents risks related to the progressive intensification of physical impacts such as the increased frequency of

extreme weather events, rising sea levels, and more limited water resources. It may also generate economic and social

challenges, requiring adjustments in certain sectors, and leading to regulatory or legal developments that could influence

regional activities.

The importance and likelihood of such risks have been assessed and have not led Sanofi to identify any material impact that could

generate a risk of impairment of the assets of Sanofi’s CGUs.

as of December 31, 2023 .

The movement in quoted equity investments included in the “Equity instruments at fair value through other comprehensive

income” category in the year ended December 31, 2025 was mainly due to increases in the stock prices of quoted equity

investments, primarily an increase in the stock price of Innovent Biologics for € 216 million .

SANOFI FORM 20-F 2025 F-47

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The main changes during previous years in quoted equity investments included in the “Equity instruments at fair value through

other comprehensive income” category are described below:

• in 2024 : t he movement in quoted equity investments included in the “Equity instruments at fair value through other

comprehensive income” was mainly due to Sanofi taking a non-controlling equity interest in Novavax in May 2024;

• in 2023 : t here were no material movements in quoted equity investments during the year ended December 31, 2023.

A 10 % decline in stock prices of the quoted equity investments included within “Equity instruments at fair value

through other comprehensive income” would have had a pre-tax impact of € 87 million on Other comprehensive income as

of December 31, 2025 .

Unquoted equity instruments

The line item “Equity instruments at fair value through other comprehensive income” also includes equity investments not quoted

in an active market with a carrying amount of € 1,331 million as of December 31, 2025 , € 1,092 million as of December 31, 2024

and € 618 million as of December 31, 2023 .

The change in unquoted equity investments included in the “Equity instruments at fair value through other comprehensive

income” category during the year ended December 31, 2025 was mainly due various equity stakes acquired through the Sanofi

Ventures fund. It also includes the following items:

• an investment of € 300 million relating to an equity interest of approximately 16 % in Orano Med Theranostics, a new entity

focused on the discovery, design, and clinical development of next-generation radioligand therapies (RLTs) based on lead-212

(212Pb) alpha-emitting isotopes. The fair value of this investment as of December 31, 2025 was € 60 million, and the fair value

adjustment of € 240 million) was recognized through Other comprehensive income ; and

The change in unquoted equity investments included in the “Equity instruments at fair value through other comprehensive

income” category during the year ended December 31, 2024 was mainly due to an investment in EUROAPI in the form of a

perpetual subordinated hybrid bond, the value of which was € 200 million at inception date and € 143 million as of December 31,

2025 (versus € 189 million as of December 31, 2024 ), plus various equity stakes acquired through the Sanofi Ventures fund.

In addition, commitments relating to equity investments classified in this asset category amounted to € 110 million as of December

31, 2025 (versus € 360 million as of December 31, 2024 and € 65 million as of December 31, 2023 ).

D.7.2. Debt instruments at fair value through other comprehensive income

The “Debt instruments at fair value through other comprehensive income” category includes quoted euro-denominated senior

bonds amounting to € 389 million as of December 31, 2025 , including € 90 million of securities obtained in exchange for financial

assets held to meet obligations to employees under post-employment benefit plans.

Sanofi held € 357 million of quoted senior bonds as of December 31, 2024 and € 346 million as of December 31, 2023 .

As regards debt instruments held to meet obligations to employees under post-employment benefit plans, an increase of 10 basis

points in market interest rates as of December 31, 2025 would have had a pre-tax impact of € 1 million on Other comprehensive

income .

As regards other quoted debt instruments, an increase of 10 basis points in market interest rates as of December 31, 2025 would

have had a pre-tax impact of € 1 million on Other comprehensive income .

Other comprehensive income recognized in respect of “Equity instruments at fair value through other comprehensive income”

and “Debt instruments at fair value through other comprehensive income” represented unrealized after-tax gains of € 415 million

for the year ended December 31, 2025 , versus unrealized after-tax gains of € 342 million for the year ended December 31, 2024

and of € 349 million for the year ended December 31, 2023 .

An analysis of the change in gains and losses recognized in Other comprehensive income , and of items reclassified to profit or

loss, is presented in Note D.15.7.

D.7.3. Other financial assets at fair value through profit or loss

The “Other financial assets at fair value through profit or loss” category mainly includes:

• a portfolio of financial investments (amounting to € 688 million as of December 31, 2025 ) held to fund a deferred

compensation plan provided to certain employees (versus € 688 million as of December 31, 2024 and € 572 million as

of December 31, 2023 );

• unquoted securities not meeting the definition of equity instruments amounting to € 230 million as of December 31, 2025

(versus € 165 million as of December 31, 2024 and € 132 million as of December 31, 2023 ). In addition, commitments relating to

unquoted securities classified in this asset category amount to € 205 million as of December 31, 2025 (compared to € 168

million as of December 31, 2024 ); and

• contingent consideration receivable by Sanofi, amounting to € 86 million as of December 31, 2025 (versus € 174 million as of

December 31, 2024 ), recorded entirely as a non-current asset and including contingent consideration receivable recognized

following the sale of Enjaymo (see note D.1) based on the probability of achieving certain levels of future sales and discounted.

If the discount rate were to increase by one percentage point, the fair value of the Enjaymo contingent consideration would

possible to estimate that recovery of the value of inventories as of the end of the reporting period is highly probable.

Following the Blueprint acquisition, a fair value remeasurement was recognized at the acquisition date on finished goods and

work-in-process inventories (see Note D.1.). The carrying amount of the fair value remeasurement is € 991 million as of December

31, 2025.

In 2025 , 2024 and 2023 , no inventories were pledged as security for liabilities .

D.10. Accounts receivable

D.12. Financial assets and liabilities measured at fair value

Under IFRS 7 (Financial Instruments: Disclosures), fair value measurements must be classified using a fair value hierarchy with the

following levels:

• level 1: quoted prices in active markets for identical assets or liabilities (without modification or repackaging);

• level 2: quoted prices in active markets for similar assets and liabilities, or valuation techniques in which all important inputs are

derived from observable market data; and

• level 3: valuation techniques in which not all important inputs are derived from observable market data.

The valuation techniques used are described in Note B.8.5.

(€ 151 million ); and Blueprint Medicines (€ 1,443 million), acquired in 2025 (see Note D.1.).

(b) In some countries, Sanofi is liable for withholding taxes and other tax charges when dividends are distributed. Consequently, Sanofi recognizes a

deferred tax liability on the reserves of French and foreign subsidiaries (approximately € 73.3 million ) which it regards as likely to be distributed in the

foreseeable future. In determining the amount of the deferred tax liability as of December 31, 2025 , Sanofi took into account changes in the ownership

structure of certain subsidiaries, and the effects of changes in the taxation of dividends in France, following the ruling of the Court of Justice of the EU in

the Steria case and the resulting amendments to the 2015 Finance Act. As of December 31, 2024 , this line includes a deferred tax liability arising from

temporary differences on investments in subsidiaries in connection with the separation of Opella; that amount was fully reversed as of December 31,

2025 following the loss of control of Opella in April 2025 (see note D.1.).

(c) Includes deferred tax assets related to restructuring provisions, amounting to € 289 million as of December 31, 2025 , € 319 million as of December 31,

2024 , and € 286 million as of December 31, 2023 .

(d) Includes deferred taxes arising on the spread tax deduction of R&D expenses, amounting to € 2,542 million as of December 31, 2025 , € 2,053 million as of

December 31, 2024 , and € 1,331 million as of December 31, 2023 .

The reserves of Sanofi subsidiaries that would be taxable if distributed but for which no distribution is planned, and for which no

deferred tax liability has therefore been recognized, totaled € 10.1 billion as of December 31, 2025 , compared with € 10.5 billion as

of December 31, 2024 and € 10.0 billion as of December 31, 2023 .

Most of Sanofi’s tax loss carry-forwards are available indefinitely. For a description of policies on the recognition of deferred tax

assets, refer to Note B.22. For each tax consolidation, the recognition of deferred tax assets is determined on the basis of profit

forecasts that are consistent with Sanofi’s medium-term strategic plan, and taking into consideration the tax consequences of

the strategic opportunities available to Sanofi within the period of availability of tax loss carry-forwards and the specific

circumstances of each tax consolidation. Deferred tax assets relating to tax loss carry-forwards as of December 31, 2025

amounted to € 3,458 million , of which € 1,622 million were not recognized (primarily composed of prior period tax liabilities

following progress of reviews with tax authorities and capital losses). This compares with € 3,010 million as of December 31, 2024

(of which € 2,039 million were not recognized) and € 2,729 million as of December 31, 2023 (of which € 1,203 million were not

recognized).

The table below shows when tax losses available for carry-forward are due to expire:

(a) Excluding tax loss carry-forwards on asset disposals. Such carry-forwards amounted to € 37 million as of December 31, 2025 , € 40 million as of

December 31, 2024 and € 5 million as of December 31, 2023 .

Use of tax loss carry-forwards is limited to the entity in which they arose. In jurisdictions where tax consolidations are in place, tax

losses can be netted against taxable income generated by entities in the same tax consolidation.

Deferred tax assets not recognized because their future recovery was not regarded as probable given the expected results of the

entities in question and unagreed tax positions amount ed to € 1,620 million in 2025 , € 2,117 million in 2024 and € 1,261 million in

2023 .

Sanofi issues debt in two currencies, the euro and the US dollar, and also invests its cash and cash equivalents in those currencies.

Sanofi also operates cash pooling arrangements to manage the surplus cash and short-term liquidity needs of foreign subsidiaries

located outside the euro zone.

To optimize the cost of debt or reduce the volatility of debt and manage its exposure to financial foreign exchange risk, Sanofi

uses derivative instruments (interest rate swaps, currency swaps, foreign exchange swaps and forward contracts) that alter the

fixed/floating rate split and the currency split of its net debt:

of December 31, 2023 ).

(b) Amounts reported within the income statement line item Fair value remeasurement of contingent consideration , and mainly comprising unrealized

gains and losses .

As of December 31, 2025 , Liabilities related to business combinations and to non-controlling interests mainly comprised:

• Following the acquisition of Blueprint in July 2025, Blueprint shareholders received one non-tradable contingent value right

(CVR) entitling the holder to receive two potential milestone payments of $ 2 and $ 4 per CVR on the attainment of future

development and regulatory milestones , respectively, for the BLU-808 project, currently in development ; the nominal value of

the contingent consideration is $ 448 million .

• Following the acquisition of Vigil in August 2025, Vigil shareholders received one non-tradable contingent value right (CVR)

entitling the holder to receive a potential milestone payment of $ 2 per CVR contingent upon the first commercial sales of

VG-3927; the nominal value of the contingent consideration is $ 114 million .

• A contingent consideration liability towards Shire Human Genetic Therapies Inc. (Shire) arising from Sanofi’s acquisition of

Translate Bio in September 2021. In a business combination carried out in December 2016 and predating the acquisition of

control by Sanofi, Translate Bio (then called Rana Therapeutics, Inc.) acquired from Shire the intellectual property rights

relating to the latter’s Messenger RNA Therapeutics (MRT) program. As of December 31, 2025 , Shire was entitled to receive the

following potential payments:

– milestone payments contingent on the launch of products based on MRT technology, and on the attainment of a specified

level of sales of those products, and

– a percentage of sales of those products .

F-66 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The fair value of the Shire liability was measured at € 531 million as of December 31, 2025 , compared with € 568 million as

of December 31, 2024 and € 441 million as of December 31, 2023 ; it was determined by applying the contractual terms to

development and sales projections which were weighted to reflect the probability of success, and discounted. If the discount

rate were to fall by one percentage point, the fair value of the Shire liability would increase by approximately 11 % .

• Following the exclusive licensing agreement on the ProXTen technology platform entered into with Vir Biotechnology in

September 2024 , Inc., Sanofi no longer has any contingent consideration liability arising from the acquisition of Amunix in

1. The fair value of that contingent consideration liability was € 137 million as of December 31, 2023.

• The MSD contingent consideration liability arising from Sanofi’s acquisition of the Sanofi Pasteur activities carried on within the

former Sanofi Pasteur MSD joint venture was extinguished during 2025 in accordance with the contractual terms. Sanofi has

no further liability in respect of this contingent consideration following settlement of the milestone linked to 2024 sales.

As of December 31, 2025, there is no contingent consideration payable in respect of already-marketed products.

The nominal amount of contingent consideration was € 72 million as of December 31, 2024 and € 133 million as of December 31,

2023 .

The figure as of December 31, 2025 includes € 1,560 million for the liability in respect of royalties payable to Sobi on net sales of Beyfortus (nirsevimab) in

the US (see Note C.2.). Given the method used to calculate royalties payable, an increase or decrease in sales forecasts would lead to a proportionate

change in the amount of the liability. The nominal value of payments estimated to be due within more than one year but less than five years is

€ 869 million; the nominal value of payments estimated to be due after more than five years is € 2,062 million.

Non-current income tax liabilities are described in Note D.19.4., and other current liabilities in Note D.19.5.

(a) In the case of “Provisions for pensions and other post-employment benefits”, the “Increases in provisions” line corresponds to rights vesting in

employees during the period, and past service cost; the “Provisions utilized” line corresponds to contributions paid into pension funds and to

beneficiaries; and the “Reversals of unutilized provisions” line corresponds to plan curtailments, settlements and amendments.

(b) The liabilities of Opella, which in 2023 were presented in the relevant balance sheet line item for each class of liability, were reclassified in 2024 to

Liabilities related to assets held for sale in accordance with IFRS 5 (see Note D.1.) .

D.19.1. Provisions for pensions and other post-employment benefits

Sanofi offers its employees pension plans and other post-employment benefit plans. The specific features of the plans (benefit

formulas, fund investment policy and fund assets held) vary depending on the applicable laws and regulations in each country

where the employees work. These employee benefits are accounted for in accordance with IAS 19 (see Note B.23.).

Sanofi’s pension obligations in four major countries represented approximately 88 % of the total value of the defined-benefit

obligation and approximately 87 % of the total value of plan assets as of December 31, 2025 . The features of the principal defined-

benefit plans in each of those four countries are described below.

France

Lump-sum retirement benefit plans

All employees working for Sanofi in France are entitled on retirement to a lump-sum payment, the amount of which depends both

on their length of service and on the rights guaranteed by collective and internal agreements. The employee’s final salary is used

in calculating the amount of these lump-sum retirement benefits. These plans represent approximately 40 % of Sanofi’s total

obligation in France.

F-68 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Defined-benefit pension plans

These plans provide benefits from the date of retirement. Employees must fulfil a number of criteria to be eligible for these

benefits. All of these plans are now closed. These plans represent approximately 60 % of Sanofi’s total obligation in France.

Germany

Top-up defined-benefit pension plan

The benefits offered under this pension plan are wholly funded by the employer (there are no employee contributions) via a

Contractual Trust Agreement (CTA) and a cross border Institution for Occupational Retirement Provision (IORP) domiciled in

Belgium, under which benefits are estimated on the basis of a career average salary. Employees are entitled to receive an annuity

under this plan if their salary exceeds the social security ceiling. The amount of the pension is calculated by reference to a range

of vesting rates corresponding to salary bands. The plan also includes disability and death benefits. This plan represents

approximately 62 % of Sanofi’s total obligation in Germany.

Sanofi-Aventis plus (SAV plus)

A top-up pension plan (SAV plus) replaced a previous top-up defined-benefit plan. New entrants joining the plan after

April 1, 2015 contribute to a defined-contribution plan that is partially funded via the company’s CTA.

All employees whose salary exceeds the social security ceiling are automatically covered by the plan. The employer’s contribution

is 14 % of the amount by which the employee’s salary exceeds the social security ceiling.

Multi-employer plan (Pensionskasse)

This is a defined-benefit plan treated as a defined-contribution plan, in accordance with the accounting policies described

in Note B.23. Currently, contributions cover the level of annuities. Only the portion relating to the future revaluation

of the annuities is included in the defined-benefit pension obligation. The obligation relating to this revaluation amounted

to € 624 million as of December 31, 2025 , versus € 682 million as of December 31, 2024 and € 744 million as of December 31, 2023 .

This plan represents approximately 25 % of Sanofi’s total defined-benefit obligation in Germany.

United States

Defined-benefit pension plans

In the United States , there are two types of defined-benefit plan:

• “qualified” plans within the meaning of the Employee Retirement Income Security Act of 1974 (ERISA), which provide

guaranteed benefits to eligible employees during retirement, and in the event of death or disability. Employees can elect to

receive a reduced annuity, in exchange for an annuity to be paid in the event of their death to a person designated by them.

An annuity is also granted under the plan if the employee dies before retirement age. Eligible employees do not pay any

contributions. These plans are closed to new entrants, and the vesting of rights for future service periods is partially frozen.

These plans represent approximately 59 % of Sanofi’s total obligation in the US;

• “non-qualified” plans within the meaning of ERISA provide top-up retirement benefits to some eligible employees depending

on the employee’s level of responsibility and subject to a salary cap. These plans represent approximately 17 % of Sanofi’s total

obligation in the US.

Healthcare cover and life insurance

Sanofi companies provide some eligible employees with healthcare cover and life insurance during the retirement period (the

company’s contributions are capped at a specified level). These plans represent approximately 24 % (or € 301 million ) of Sanofi’s

total obligation and 2 % (or € 13 million ) of total plan assets in the US.

United Kingdom

Defined-benefit pension plans

Sanofi operates a number of pension plans in the United Kingdom that reflect past acquisitions. The most significant

arrangements are defined-benefit plans that have been closed since October 1, 2015. With effect from that date, employees can

no longer pay into these plans.

Under these defined-benefit plans, an annuity is paid from the retirement date. This annuity is calculated on the basis of the

employee’s length of service as of September 30, 2015, and of the employee’s final salary (or salary on the date he or she leaves

Sanofi).

The rates used for the vesting of rights vary from member to member. For most members, rights vest at the rate of 1.25 % or 1.50 %

of final salary for each qualifying year of service giving entitlement. The notional retirement age varies according to the category

to which the member belongs, but in most cases retirement is at age 65 . Members may choose to retire before or after the

notional retirement age ( 60 years), in which case the amount of the annual pension is adjusted to reflect the revised estimate of

the length of the retirement phase. Pensions are usually indexed to the Retail Price Index (RPI). Members paid a fixed-percentage

contribution into their pension plan (the percentage varied according to the employee category), and the employer topped up

the contribution to the required amount. These plans represent approximately 100 % of Sanofi’s total obligation in the United

Kingdom.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

In November 2024, a bulk annuity purchase transaction, commonly known as a “buy-in”, was executed for the main

defined-benefit pension scheme in the United Kingdom covering the majority of uninsured pension liabilities. Through this

transaction, and in conjunction with the previous pensioner buy-in executed in 2021, the main defined-benefit pension plan in the

United Kingdom is largely insured against investment, longevity, interest rate and inflation risks. Pension obligations will be

funded by the insurer’s annuity payments and the buy-in policies are held as an asset of the pension scheme. The pension

scheme retains full legal responsibility to pay the benefits to plan participants using insurance payments. The insurance contract

is deemed to be the present value of the matched obligations. In early 2025, Sanofi completed a further buy-in covering the

remaining uninsured liabilities meaning all members of the scheme are now fully insured by the transaction, except those arising

from guaranteed minimum pensions equalization.

For service periods subsequent to October 1, 2015, employees belong to a new defined-contribution plan.

Actuarial assumptions used to measure Sanofi’s obligations

Actuarial valuations of Sanofi’s benefit obligations were computed by management with assistance from external actuaries as

of December 31, 2025 , 2024 and 2023 .

Those calculations were based on the following financial and demographic assumptions:

	2025 — France	Germany	US	UK	2024 — France	Germany	US	UK	2023 — France	Germany	US	UK
Discount rate (a)(b)	3.10 % to 4.05 %	3.10 % to 4.05 %	5.20 %	5.50 %	2.95 % to 3.40 %	2.95 % to 3.40 %	5.45 %	5.50 %	2.95 % to 3.15 %	2.95 % to 3.15 %	4.75 %	4.50 %

(a) The discount rates used were based on market rates for high quality corporate bonds with a duration close to that of the expected benefit payments

under the plans. The benchmarks used to determine discount rates were the same for all periods presented.

(b) The rate depends on the duration of the plan ( 0 to 7 years, 7 to 10 years, or more than 10 years).

(c) Inflation for the euro zone is determined using a multi-criterion method.

(d) No post-employment healthcare benefits are provided in France since 2020, Germany and UK .

Sanofi has a long-term objective of maintaining or increasing the extent to which its pension obligations are covered by assets.

To this end, Sanofi uses an asset-liability management strategy, matching plan assets to its pension obligations. This policy aims

to ensure the best fit between the assets held on the one hand, and the associated liabilities and expected future payments to

plan members on the other. To meet this aim, Sanofi operates a risk monitoring and management strategy (mainly focused on

interest rate risk and inflation risk), while investing a growing proportion of assets in high-quality bonds with comparable

maturities to those of the underlying obligations and in contracts entered into with leading insurance companies to fund certain

post-employment benefit obligations.

(a) Provisions utilized mainly correspond to payments related to employees affected by separation programs.

(b) This line comprises the restructuring provisions of Opella, reclassified to Liabilities related to assets held for sale as of December 31, 2024

(see Note D.1.).

Provisions for employee termination benefits as of December 31, 2025 amounted to € 1,107 million (compared with € 1,318 million

as of December 31, 2024 and € 968 million as of December 31, 2023 ).

The provisions apply mainly to France, and relate to various voluntary redundancy programs:

• Sanofi’s Strategic Orientations in France for the period 2024 – 2026 , announced in March 2024 , which provide for internal

transfer and outplacement opportunities for employees whose jobs are subject to transformation, and include an end-of-

career paid leave component and an external retraining component. Implementation of this plan began in 2024 under the

terms of the Jobs Management and Career Paths (GEPP) agreement signed in 2022 and applicable until December 31, 2024 . In

May 2025 , a new GEPP agreement was signed for a period of four years until June 30, 2029 . This new agreement aims to give

added impetus to job mobility, and to provide further internal and external support for employees with "sensitive" job profiles.

The provisions initially recognized were re-estimated during the 2025 financial year to reflect the newly signed agreement;

• Sanofi’s Strategic Orientations in France for the period 2022 – 2024 , announced in June 2022 , which provide for internal

transfer and outplacement opportunities for employees whose jobs are subject to transformation, and include an end-of-

career paid leave component and an external retraining component. Implementation of this plan began in 2022 under the

terms of the Jobs Management and Career Paths (GEPP) agreement relating to several French legal entities, signed in

February 2022 and applicable until December 31, 2024 . Increases in provisions recognized in 2023 reflect an update to the

scope of “sensitive” job profiles; reversals were mainly due to the adoption of the Borne law, which raised the retirement age

to 64, and hence disqualified some participants eligible under previous legislation (in light of the maximum period for portage

workers);

• a voluntary redundancy program announced in 2024 in connection with the reorganization of R&D operations to make Sanofi

a leader in immunology, including an end-of-career paid leave plan and an end-of-career transition plan; and

• collectively agreed separation programs involving a number of legal entities announced at the end of June 2020 as part of the

rollout of the “Play to Win” strategy; these include an end-of-career paid leave plan and an external retraining program, and

were still ongoing during 2025 . The same applies to Sanofi-Aventis Recherche & Développement, which announced a

voluntary redundancy program associated with R&D reorganization in 2020 , and implemented that program in 2021 .

The provision includes the present values of:

• gross annuities for self-funded plans;

• employer’s social security charges on early retirement annuities for all plans (outsourced and self-funded); and

• the levy charged on those annuities under the “Fillon” law (only for plans with termination of employment contracts).

The average residual portage periods under thes e plans were 2.26 years, 2.18 years and 2.22 year s as of December 31, 2025 , 2024

and 2023 , respectively.

The main other countries covered by restructuring provisions are Germany, Japan and the US.

Product liability risks, litigation and other	1,127	1,676	1,283
Total	1,620	2,150	1,776

Provisions for environmental risks relate primarily to contingencies arising from business divestitures, and include remediation

costs relating to such environmental risks.

Identified environmental risks are covered by provisions estimated on the basis of the costs Sanofi believes it will be obliged to

meet over a period not exceeding (other than in exceptional cases) 30 years. Sanofi expects that € 56 million of those provisions

will be utilized in 2026 , and € 279 million over the period from 2027 through 2030 .

As regards greenhouse gas emission quotas, which relate to Sanofi production facilities in France and Ireland , in the absence of

specific IFRS pronouncements Sanofi has adopted the "net liability approach". That involves recognizing a liability at the balance

sheet date if actual emissions exceed the quotas held, in accordance with IAS 37 and French GAAP ( Plan Comptable Général,

Article 615-1s). Quotas are managed as a production cost, and as such are recognized in inventory at a zero value (if received free

of charge) and at acquisition cost (if bought on the market). As of December 31, 2025 , a provision of € 1 million has been

recognized.

“Product liability risks, litigation and other” mainly comprises provisions for risks relating to product liability (including IBNR

provisions as described in Note B.12.), government investigations, regulatory or antitrust law claims, contingencies arising from

business divestitures (other than environmental risks), and remediation costs related to leases.

The main pending legal and arbitral proceedings and government investigations are described in Note D.22.

A full risk and litigation assessment is performed with the assistance of Sanofi’s legal advisers, and provisions are recorded as

required by circumstances in accordance with the principles described in Note B.12.

D.19.4. Non-current income tax liabilities

Non-current income tax liabilities amounted to € 2,081 million as of December 31, 2025 (versus € 1,512 million as of December 31,

2024 and € 1,842 million as of December 31, 2023 ). These amounts include uncertainties over income tax treatment totalling

€ 2,081 million as of December 31, 2025 , versus € 1,512 million as of December 31, 2024 and € 1,595 million as of December 31, 2023 .

Until December 31, 2023 , this line item includes the residual liability due after more than one year arising from the estimated tax

charge on deemed repatriation attributable to the accumulated earnings of non-US operations (€ 247 million as of December 31,

2023 ). The expense was initially recognized in 2018 at an amount of $ 1,092 million , and payment is being made over eight years

through 2025 .

A US legal restructuring resulted in a capital loss of € 3 billion recognized in the 2020 final tax filing. One-third of the capital loss

has been used against 2020 capital gains and the remaining balance has been carried back on the 2017 capital gains. Due to

management’s judgment about potential alternative interpretations of the prevailing tax law, no tax benefit has been recognized

on this transaction in accordance with IFRIC 23.

healthcare authorities and governmental programs (see Note D.23.); and the liability payable at each reporting date under the Monoclonal Antibody

Alliance with Regeneron.

(b) As of December 31, 2025 includes € 147 million (nominal value: € 155 million) for the current liability relating to royalties payable to Sobi on net sales of

Beyfortus (nirsevimab) in the United States (see Note C.2.) .

Objectives of the use of derivative financial instruments

Sanofi uses derivative instruments to manage operating exposure to movements in exchange rates, and financial exposure to

movements in interest rates and exchange rates (where the debt or receivable is not contracted in the functional currency of the

borrower or lender entity). On occasion, Sanofi uses equity derivatives in connection with the management of its portfolio of

equity investments.

Sanofi performs periodic reviews of its transactions and contractual agreements in order to identify any embedded derivatives,

which are accounted for separately from the host contract in accordance with IFRS 9. Sanofi had no material embedded

derivatives as of December 31, 2025 , 2024 or 2023 .

SANOFI FORM 20-F 2025 F-81

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The “Research and development license agreements” line comprises future service commitments to fund research and

development or technology, and contingent milestone payments regarded as reasonably achievable (i.e. all potential milestone

payments relating to projects in the development phase, for which the future financial consequences are known or probable and

for which there is a sufficiently reliable estimate). This line excludes:

• commitments given relating to (i) projects in the research phase, amounting to € 13.9 billion as of December 31, 2025 and

€ 14.4 billion as of December 31, 2024 and (ii) payments contingent upon the attainment of sales targets once a product is

commercialized, amounting to € 15.6 billion as of December 31, 2025 and € 15.2 billion as of December 31, 2024 ;

• commitments received amounting to € 9.0 billion as of December 31, 2025 ( € 12.5 billion as of December 31, 2024 ),

mainly comprising research, development and commercialization agreements with partners further to the acquisitions

of (i) Ablynx ( € 0.7 billion as of December 31, 2025 , versus € 0.7 billion as of December 31, 2024 ) and (ii) Kymab (€ 0.2 billion as

of December 31, 2025 , versus € 0.3 billion as of December 31, 2024 ), plus contingent consideration receivable based on

attainment of regulatory and sales milestones for commercialized products under the terms of licenses or rights assignment

agreements amounting to € 7.5 billion as of December 31, 2025 (€ 11.2 billion as of December 31, 2024 ).

Sanofi entered into one major agreement in 2025 , as described below:

• in April 2025 , Sanofi entered into a license and collaboration agreement with Earendil Labs for two bispecific antibodies in the

field of autoimmune and inflammatory bowel diseases: HXN-1002 (targeting α4β7 and TL1A for potential treatment of

moderate to severe ulcerative colitis and Crohn's disease) and HXN-1003 (targeting TL1A and IL23 for potential treatment of

colitis and skin inflammation). Under the terms of the agreement, Earendil Labs received an upfront payment of $ 125.0 million,

and is eligible to receive (i) up to $ 1.7 billion in development and commercial milestone payments and (ii) tiered royalties on

product sales.

In addition, by acquiring all of the outstanding shares of Blueprint in July 2025 and Vigil in August 2025 (see Note D.1.), Sanofi

assumed commitments amounting to € 1,606 million and € 208 million, respectively, made by those companies to various partners

under collaboration agreements previously entered into.

The amount reported for commitments as of December 31, 2025 also includes commitments under agreements entered into by

Sanofi in prior years. The main such agreements are described below; for a full description of each agreement, refer to the Annual

Report on Form 20-F for the year in which the agreement was entered into.

The major agreements entered into by Sanofi in 2024 are described below:

• C o-exclusive licensing agreement with Novavax. The terms of the agreement include (i) a co-exclusive license to co-

commercialize Novavax’s current stand-alone adjuvanted COVID-19 vaccine worldwide (except in countries with existing

Advance Purchase Agreements and in India, Japan, and South Korea, where Novavax has existing partnership agreements);

(ii) a sole license to Novavax’s adjuvanted COVID-19 vaccine for use in combination with Sanofi’s flu vaccines; and (iii) a non-

exclusive license to use the Matrix-M adjuvant in vaccine products. Novavax received an upfront payment of $ 500 million and

could receive up to $ 700 million contingent on attainment of development, regulatory and commercialization milestones,

representing up to $1.2 billion in total. Starting in 2025, Sanofi recognizes sales of Novavax’s adjuvanted COVID-19 vaccine and

bears certain R&D, regulatory and commercialization expenses. Novavax will receive double-digit tiered royalties on Sanofi

sales of COVID-19 vaccines and combined influenza/COVID-19 vaccines. Novavax is also entitled to additional launch and sales

milestone payments of up to $ 200 million, plus single-digit royalties for each additional Sanofi vaccine product developed

under a non-exclusive license using Novavax’s Matrix-M adjuvant technology. In addition, Sanofi took a minority equity interest

of less than 5% in Novavax. Outside of the collaboration, each party may develop and commercialize their own flu and

COVID-19 vaccines and their own adjuvanted products at their own cost.

• Exclusive licensing agreement with RadioMedix, Inc. and Orano Med for AlphaMedix (SAR447873), a late-stage project

currently being evaluated for the treatment of adult patients with unresectable or metastatic progressive somatostatin-

Sanofi did not discontinue any collaboration agreement that would have resulted in a significant reduction in commitments as of

December 31, 2025 .

In addition, under the collaboration agreement with Regeneron on monoclonal antibodies (see Note C.1.), Sanofi is entitled to

receive an additional share of quarterly profits (capped at 10 % of Regeneron’s share of quarterly profits until March 31, 2022, and

thereafter at 20 % ), until Regeneron has paid 50 % of the cumulative development costs incurred by the parties to the alliance.

As of December 31, 2025 this represented total commitments received of € 0.5 billion (versus € 1.6 billion as of December 31,

2024 ), against cumulative development costs of € 9.0 billion .

Sanofi entered into an agreement with Royalty Pharma in December 2014 relating to development programs, under which

Royalty Pharma bore a portion of the remaining development costs of the project on a quarterly basis in return for royalties on

future sales. The products in development under that agreement have been launched in territories including the US and Europe,

marking the end of the joint development programs.

On February 27, 2017, Sanofi and Lonza announced a strategic partnership in the form of a joint venture (BioAtrium AG) to build

and operate a large-scale mammalian cell culture facility for monoclonal antibody production in Visp, Switzerland. An initial

investment of approximately € 0.3 billion to finance construction of the facility, split 50 / 50 between the two partners, has now

been made in full. In addition, Sanofi could pay BioAtrium AG in the region of € 0.8 billion over the 2026-2031 period as its share

of operating expenses and the cost of producing future batches.

In February 2014, pursuant to the “Pandemic Influenza Preparedness Framework for the sharing of influenza viruses and access to

vaccines and other benefits” (still effective as of December 31, 2025 ), Sanofi and the World Health Organization (WHO) signed a

bilateral “Standard Material Transfer Agreement” (SMTA 2). This agreement stipulates that Sanofi will, during declared pandemic

periods, (i) donate 7.5 % of its real-time production of pandemic vaccines against any strain with potential to cause a pandemic,

and (ii) reserve a further 7.5 % of such production on affordable terms. The agreement cancels and replaces all preceding

commitments to donate pandemic vaccines to the WHO.

Off balance sheet commitments of a financing nature with associates and joint ventures are disclosed in N ote D.6.

F-84 SANOFI FORM 20-F 2025

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Off balance sheet commitments relating to securities classified in the categories “Equity instruments at fair value through other

comprehensive income” and “Unquoted debt securities not meeting the definition of equity instruments” are respectively

disclosed in Notes D.7.1. and D.7.3..

The maximum amount of contingent consideration relating to business combinations in accordance with IFRS3 is disclosed in

Note D.18.

Contingent milestone payments in connection with acquisitions of groups of assets are disclosed in Note D21.1. (e) .

D.22. Legal and arbitral proceedings

Sanofi and its affiliates are involved in litigation, arbitration and other legal proceedings. These proceedings typically are related

to product liability claims, intellectual property rights (particularly claims against generic companies seeking to limit the patent

protection of Sanofi products), competition law and trade practices, commercial claims, employment and wrongful discharge

claims, tax assessment claims, waste disposal and pollution claims, and claims under warranties or indemnification arrangements

relating to business divestitures. Provisions related to legal and arbitral proceedings are recorded in accordance with the

principles described in Note B.12.

Most of the issues raised by these claims are highly complex and subject to substantial uncertainties; therefore, the probability of

loss and an estimation of damages are difficult to ascertain. Contingent liabilities are cases for which either we are unable to

make a reasonable estimate of the expected financial effect that will result from ultimate resolution of the proceeding, or a cash

outflow is not probable. In either case, a brief description of the nature of the contingent liability is disclosed and, where

practicable, an estimate of its financial effect, an indication of the uncertainties relating to the amount and timing of any outflow,

and the possibility of any reimbursement are provided in application of paragraph 86 of IAS 37.

In the cases that have been settled or adjudicated, or where quantifiable fines and penalties have been assessed, we have

indicated our losses or the amount of provision accrued that is the estimate of the probable loss.

In a limited number of ongoing cases, while we are able to make a reasonable estimate of the expected loss or range of the

possible loss and have accrued a provision for such loss, we believe that publication of this information on a case-by-case basis or

by class would seriously prejudice the Company’s position in the ongoing legal proceedings or in any related settlement

discussions. Accordingly, in those cases, we have disclosed information with respect to the nature of the contingency but have

not disclosed our estimate of the range of potential loss, in accordance with paragraph 92 of IAS 37.

These assessments can involve a series of complex judgments about future events and can rely heavily on estimates and

assumptions. Our assessments are based on estimates and assumptions that have been deemed reasonable by management. We

believe that the aggregate provisions recorded for the above matters are adequate based upon currently available information.

However, given the inherent uncertainties related to these cases and involved in estimating contingent liabilities, we could in the

future incur judgments that could have a material adverse effect on our net income in any particular period.

Long-term provisions are disclosed in Note D.19. They include:

• provisions for product liability risks, litigation and other amount to € 1,127 million in 2025 . These provisions are mainly related to

product liabilities, government investigations, competition law, regulatory claims, warranties in connection with certain

contingent liabilities arising from business divestitures other than environmental matters and other claims;

• provisions for environmental risks and remediation amount to € 493 million in 2025 , the majority of which are related to

contingencies that have arisen from business divestitures.

a) Products

Sanofi Pasteur Hepatitis B Vaccine Product Litigation

Since 1996, more than 180 lawsuits have been filed in various French civil courts against Sanofi Pasteur (a French subsidiary of

Sanofi) and/or Sanofi Pasteur MSD SNC (a now terminated joint venture company with Merck & Co. Inc.), for which past ongoing

litigation is now managed by the originating party. In such lawsuits, the plaintiffs allege that they suffer from a variety of

neurological disorders and autoimmune diseases, including multiple sclerosis and Guillain-Barré syndrome, as a result of receiving

the hepatitis B vaccine.

In January 2018, the Appeal Court of Bordeaux found a causal link between the hepatitis B vaccine and multiple sclerosis. In July

2019, the French Supreme Court (Cour de cassation) canceled the judgment of the Appeal Court of Bordeaux and referred

the case back to the Appeal Court of Toulouse. On March 30, 2022, the Appeal Court of Toulouse dismissed all the plaintiffs'

claims.

As of December 31, 2025 , there was one ongoing lawsuit related to Sanofi's hepatitis B vaccine.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Taxotere Product Litigation in the US

Thousands of lawsuits have been filed against affiliates of Sanofi under US state law for personal injuries allegedly sustained in

connection with the use of Taxotere. The actions have been held in several jurisdictions around the country. In 2021, there were

two bellwether trials as part of a federal multi-district litigation in the Eastern District of Louisiana both resulting in jury verdicts in

Sanofi's favor. Throughout 2024, Sanofi entered into a number of settlement agreements or agreements in principle with many

plaintiffs’ firms encompassing nearly all the remaining cases. These agreements were mostly completed over the course of 2025

as they required the consent of the individual plaintiffs which has taken some time to conclude. Sanofi is near the end of the

settlement process and expects approximately 250 plaintiffs to opt out of the settlement and for litigation to continue.

It is not possible, at this stage, to assess with certainty the outcome of these ongoing lawsuits.

Zantac Litigation in the US

In September 2019, the US Food and Drug Administration (FDA) announced it was investigating the claims of an online

pharmacy’s Citizen Petition that the medication Zantac (the brand name for ranitidine) used for stomach heartburn contains or

can generate the chemical N-Nitrosodimethylamine (NDMA), an alleged human carcinogen. As a precautionary measure, Sanofi

initiated a voluntary recall of branded over-the-counter Zantac in October 2019. Concurrent with the FDA investigation, multiple

personal injury lawsuits and class actions alleging that Zantac causes various cancers and seeking damages for either alleged

personal injuries or alleged economic injuries were filed.

Federal court cases were coordinated into a Multi-District Litigation (MDL) in the Southern District of Florida in February 2020.

On December 6, 2022, the MDL Court granted Sanofi and other defendants’ Daubert motions to exclude plaintiff's experts and

summary judgment motions. As a result, the Court entered final judgment in all cases involving plaintiffs’ five designated cancers

and dismissed the class action cases. The MDL Court subsequently dismissed all pending cases alleging a non-designated cancer

for failure to serve expert reports. Approximately 7,900 plaintiffs with cases against Sanofi have filed notices to appeal the

Daubert ruling in the Eleventh Circuit. The Eleventh Circuit held oral argument for the appeal in the fourth quarter of 2025 and a

decision is expected in the second quarter of 2026.

The majority of the state court plaintiffs have cases pending in Delaware, where a hearing on defendants’ Daubert motions to

exclude plaintiffs’ experts took place in January 2024. In May 2024, the State of Delaware court decided not to exclude plaintiffs’

experts from the cases. Sanofi appealed this decision to the Delaware Supreme Court, which granted review. In April 2025, Sanofi

reached several settlement agreements that in total resolve a majority of the Delaware State Court consolidated litigation.

On July 10, 2025, the Delaware Supreme Court unanimously reversed the Superior Court’s (Delaware State Court) denial of

defendants’ Daubert motion based on the lack of reliability of plaintiff’s experts on causation and remanded its findings back to

the Superior Court for proceedings consistent with the rulings in the opinion. On December 1, 2025, the Delaware Superior Court

denied plaintiff’s request to have a rehearing on Daubert grounds and ordered that summary judgment briefing conclude in the

first quarter of 2026 to determine if the remaining cases will be dismissed.

To date, there have been ten trials against other defendants, but none against Sanofi as yet.

In March 2024, Sanofi reached agreement in principle with a number of plaintiffs’ lawyers to resolve Zantac personal injury cases

pending against it in all US state courts outside of Delaware. This agreement would resolve the majority of the cases outside of

Delaware and the MDL.

Overall, as of December 31, 2025, there were around 18,765 remaining individual product liability “plaintiffs” who have all filed

against Sanofi and who are not part of any settlements. The vast majority of these plaintiffs are in either the MDL or Delaware.

Additional cases may be filed.

In addition, in November 2019, Sanofi received a Civil Investigative Demand (CID) related to this issue from the Arizona Attorney

General. Sanofi provided responses in December 2019 and July 2020 and has not received any follow-up requests.

In June 2020, the New Mexico Attorney General filed a complaint against Sanofi for alleged violations of the New Mexico Unfair

Practices Act, violations of the New Mexico False Advertising Act, violations of the New Mexico Public Nuisance Statute, common

law public nuisance, and negligence. This matter was settled in 2025 and is now concluded.

In June 2020, Sanofi received a notice from the US Department of Justice Civil Division and US Attorney’s Office for the Eastern

District of Pennsylvania of an investigation into allegations that pharmaceutical manufacturers violated the False Claims

Act, 31 U.S.C. § 3729, in relation to the drug Zantac and ranitidine hydrochloride through alleged failure to disclose to the federal

government information about the potential presence of NDMA. In response to the notice, Sanofi provided information and

documents including applications and communications with FDA, in August 2020. Sanofi has not received any subsequent

requests from the federal government.

In November 2020, the City Council of Baltimore filed a complaint against Sanofi for alleged violations of the Maryland Consumer

Protection statute, public nuisance, and negligence. This matter was settled in 2025 and is now concluded.

It is not possible, at this stage, to assess with certainty the outcome of the ongoing lawsuits.

Zantac Litigation in Canada

Between 2019 and 2022, seven proposed class actions naming some or all of Sanofi Consumer Health Inc., Sanofi-Aventis Canada

Inc., Chattem (Canada) Inc., Sanofi and Sanofi Pasteur Limited as Defendants, relating to ranitidine were filed in courts in various

Canadian provinces. The cases allege that proposed class members suffered personal injury from the ingestion of ranitidine, and

seek damages in unspecified amounts, disgorgement of profits, restitution in the amount of the purchase price of Zantac and

subrogated damages on behalf of provincial health insurers for health care costs related to ranitidine use.

Between 2021 and 2025, a total of 124 individual claims naming Sanofi Consumer Health Inc., Sanofi-Aventis Canada Inc., Sanofi

Pasteur Limited and Chattem (Canada) Inc. were filed in Ontario and British Columbia.

In May 2023, in the proceedings pending before the Supreme Court of British Columbia, the court dismissed the action, ruling

that there is no scientific support for the plaintiffs' claims. The Superior Court of Quebec has stayed the corresponding proposed

Zantac class proceedings in Quebec until the result of the US Multi-District Litigation (MDL) appeal is announced.

It is not possible, at this stage, to assess with certainty the outcome of the remaining lawsuits.

Talc Product Litigation in the US

Over the last few years, Sanofi affiliates have been named in product liability actions in the US regarding the alleged presence of

asbestos in talc products originating from past acquisitions. A certain number of these claims were also dismissed during that

time. As of December 31, 2025, there were approximately 1,200 ongoing product liability actions. To date, no cases have

proceeded to trial.

It is not possible, at this stage, to assess with certainty the outcome of these ongoing lawsuits.

Depakine Product Litigation in France

Civil proceedings

As of December 31, 2025 , 82 families had brought a civil claim involving 136 people exposed in utero to sodium valproate against

a French affiliate of Sanofi seeking indemnification under French law for personal injuries allegedly suffered by children in

connection with the use of sodium valproate (Depakine) by their mothers during pregnancy to treat their epilepsy. These actions

are being held in several jurisdictions in France.

Forty lawsuits have been initiated on the merits, the most advanced of which was tried at the level of the French Supreme Court,

which in November 2019 issued a ruling sending the case before the Paris Appeal Court to rule on Sanofi’s argument on the

compliance of the product with mandatory regulations, as well as on the question of defectiveness of the product and the

assessment of damages. This proceeding is currently pending.

Nine first instance rulings on the merits were handed down by the Judicial Tribunal of Nanterre. In three cases, the Court

declared the judicial expert report null and void and the Court dismissed one claim in another case.

Concerning five other cases relating to births that occurred between 2005 and 2009, the Court held, on the basis of a non-fault

liability, that Sanofi was liable in light of the wording of the patient information leaflet. Provisional compensation amounts were

set in the range of € 0.1 million to € 0.5 million in three cases. In the other two cases, expert proceedings have been ordered to

assess the damages.

All the judgments have been appealed and are still pending.

In the class action lawsuit filed in May 2017 by the APESAC (Association des Parents d’Enfants souffrant du Syndrome de l’Anti-

Convulsivant) against the French affiliate, the Judicial Tribunal of Paris ruled on January 5, 2022 that a class is admissible,

retaining Sanofi’s liability between 1984 and January 2006 for malformations and between 2001 and January 2006 for

neuro-developmental disorders (NDD). This decision is based on the conclusions of a criminal expert report within the frame of

ongoing criminal proceedings, for which the Chambre de l’Instruction of the Appeal Court of Paris had ordered a counter-

expertise (see below). The APESAC, Sanofi and its insurers appealed the Judicial Tribunal of Paris’ ruling related to the class

action. This proceeding is currently pending and a stay of proceedings has been ordered awaiting a ruling from the European

Court of Justice (ECJ) (see below).

On July 21, 2021, the Judicial Tribunal of Créteil dismissed a claim for damages brought against Sanofi regarding a child born

in 1995. The Judicial Tribunal considered that the risk of occurrence of NDD in children born to a mother exposed to sodium

valproate during pregnancy was not demonstrated by the state of scientific knowledge at the time of her pregnancy. This

decision was appealed and the proceeding is now pending before the Appeal Court of Paris, which had ordered a stay in the

proceeding until the end of the criminal investigation.

Several questions on the Product Liability Directive have been referred to the ECJ, which will have an impact on the pending

Depakine cases. A ruling from the ECJ is expected during the first quarter of 2026.

Since July 2020, several collective claims have been filed before the Nanterre civil court against the French affiliate representing

at December 2025 approximately 369 claimants including 136 people exposed in utero , seeking indemnification for a prejudice of

anxiety. Part of these claims are currently before the Versailles Court of Appeal on arguments on admissibility and a stay in the

proceedings has been ordered on part of the claims pending the awaited ECJ ruling.

Criminal investigation

A criminal investigation was initiated in May 2015 before the Paris Civil Court. In January 2020, the French affiliate of Sanofi was

indicted for aggravated deception and involuntary injuries and in July 2020 for involuntary manslaughter. In July 2020, a judicial

supervision of the affiliate was ordered, together with the implementation of financial guarantees. In November 2020, the Health

Authority ( ANSM) was similarly indicted for involuntary injuries and involuntary manslaughters.

On March 9, 2022, the Chambre de l’Instruction of the Appeal Court of Paris (Cour d’appel) ruled that certain complaints for

involuntary manslaughter and several others for aggravated deception and involuntary injuries were time-barred. This decision

was confirmed by the Chambre Criminelle of the French Supreme Court ( Cour de cassation ) in June 2023. In September 2022,

the investigating judges appointed two experts for a counter-expertise following the Chambre de l’Instruction’s ruling handed

down end of 2021. The counter-expertise report was delivered in 2023. Since 2022, several individual medical assessments have

been ordered by the investigating judge.

Public compensation scheme

In 2017, the French government set up a public compensation scheme to indemnify patients for damages suffered in connection

with the prescription of sodium valproate and its derivatives. The scheme was further amended through the 2020 Finance Law,

with notably the introduction of presumptions of failure to inform the mother since 1982 for malformations and since 1984 for

NDD. The scheme was amended again through the 2021 Finance Law in order to increase the maximum premium applicable in

the event of refusal to make an offer (or making an insufficient offer) where this would be deemed unjustified by a court ruling.

The committee of the compensation scheme has issued several final opinions holding the French affiliate liable for damages

either in full or in part along with the French State, and, in some cases, healthcare practitioners. The French affiliate disagreed

with the committee’s conclusions and has accordingly not offered indemnification to the claimants who have received

compensation from the ONIAM (Office National d’Indemnisation des Accidents Médicaux) . The ONIAM is now seeking

reimbursement from Sanofi, which has filed legal actions to oppose ONIAM’s payment orders.

Administrative Actions

In July 2020, March and June 2021, the Montreuil Administrative Court held the French State liable in five administrative

proceedings initiated by families against the State. In March 2021, the Administrative Court did not find any failure to inform the

mother regarding the risk of neurodevelopmental disorders for births in 1999 and in 2002, based on the state of scientific

knowledge at the time. However, regarding the risk of malformations, liabilities were retained against the State, the healthcare

professionals and Sanofi, notably for discrepancy between the SmPC (Summary of the Product Characteristics) and the patient

leaflet. In other cases involving births in 2005-2008, the State was held liable both for malformations and neurodevelopmental

disorders but partially exonerated, taking into account the roles of healthcare practitioners and Sanofi. Given that the French

affiliate was not a party to these administrative proceedings, its arguments (including several requests from the French affiliate to

the Health Authorities to reinforce warnings to healthcare professionals and patients in relation to Depakine) were not

considered.

All rulings were appealed by the claimants. Sanofi has filed requests for voluntary intervention in some of these proceedings to

present its arguments before the Administrative Court of Appeal, which has been granted for some of them. In one proceeding,

the claimants decided to withdraw their claims. In January 2025, the Paris Administrative Court of Appeal handed down five

rulings. In cases concerning births in 2006 onwards, the Court retained the State’s liability and no fault from Sanofi due to the

reiterated variation requests of the medicine’s information documents. In a case concerning births in 1999 and 2002, the Court

retained the State’s liability with a 50% liability retained for Sanofi.

In February 2025, the Versailles Administrative Court of Appeal, in a proceeding concerning births subsequent to 2006, held the

State liable and no faul t by Sanofi due to reiterated requests for alterations of the medicine’s information documents.

It is not possible, at this stage, to make a reliable assessment of the outcome of these cases.

Depakine Product Litigation in other EU countries, in the UK and Switzerland

In Switzerland, eleven families have filed a civil claim for damages concerning seventeen people exposed in utero to sodium

valproate. Some of them also involve the claimants’ physicians. In November 2022, one action was declared time-barred by the

judge. The claimant appealed this court decision on the merits. In November 2024, the court confirmed the first instance

judgment. The claimant appealed against this court decision to the Federal Tribunal (last instance).

In Spain, there are seven ongoing actions relating to fourteen people. In March 2022, in one trial, the Court ordered Sanofi to

indemnify four patients. Sanofi appealed this decision. In January 2023, in another trial filed by one patient, the Court of Appeal

confirmed the first instance's decision and dismissed the claim. As of January 2026, one claim is pending in front of the Supreme

Court, another one has been dismissed by the Court of Appeal (but could still be appealed before the Supreme Court) and five

are at the first instance stage.

In Belgium, there are two civil proceedings (currently on hold). A criminal action was discontinued by the Court of Appeal in

September 2025.

In Ireland, there are two cases in Pre-Action stage, two civil claims and one non-statutory public inquiry ongoing.

In the United Kingdom, there is one case in the Pre-Action stage in Great Britain and one civil claim ongoing in Northern Ireland.

Dengvaxia (Philippines)

From early 2018 up to present date, several claims have been filed in the Philippines by parents of deceased children whose

deaths were allegedly due to vaccination with Dengvaxia. In early March 2019 and in 2020 and 2022, the Philippine Department

of Justice (DOJ) prosecution panel announced it had found probable cause to indict several Sanofi employees/former employees

and former Government officials for “reckless imprudence” resulting in homicides. Since then, several criminal actions have been

filed in court as a result of this finding and are pending at various stages of the legal procedure. Petitions for Review to the DOJ

Secretary have been filed and the said petitions remain pending. Meanwhile, the majority of the respondents have challenged the

jurisdiction of the lower court where the first eight cases had been assigned and this issue was filed with the Supreme Court.

There are several claims that have not yet been filed in any court despite resolutions by the DOJ that there is probable cause.

In July 2024, the Court dismissed the first eight criminal cases, ruling the prosecution failed to establish the elements of “reckless

imprudence” resulting in homicide. The DOJ has resolved there is probable cause to proceed on the remaining cases but no case

has been filed in court to date. In 2025, four additional criminal cases were filed and remain pending with the DOJ.

b) Patents

Praluent (alirocumab)-related Amgen Patent Litigation in the US

In 2014, Amgen Inc. (Amgen) filed four separate complaints against Sanofi and Regeneron in the US District Court for the District

of Delaware (“District Court”) asserting patent infringement relating to Sanofi and Regeneron’s Praluent product. Together these

complaints alleged that Praluent infringed seven patents for antibodies targeting PCSK9 and sought injunctive relief and

unspecified damages.

In February 2021, the Federal Circuit affirmed the District Court’s ruling invalidating the Amgen asserted patent claims.

In November 2021, Amgen filed a petition with the US Supreme Court, asking it to overturn the Federal Circuit decision.

On November 4, 2022, the US Supreme Court granted Amgen’s petition for review. In May 2023, the Supreme Court issued a

unanimous decision in favor of Sanofi and Regeneron regarding the patent infringement actions filed in 2014 by Amgen relating

to Sanofi and Regeneron’s Praluent product. Sanofi and Regeneron received legal costs from Amgen in an amount of $932,000.

As of March 2025, these matters are now closed.

Praluent (alirocumab)-related Amgen Patent Litigation in Europe

In June 2023, Amgen filed an action for infringement of EP 3 666 797 against Sanofi and Regeneron concerning Praluent in the

Munich Local Division of the Unified Patent Court (UPC). Amgen seeks a permanent injunction and unspecified damages and

compensation from March 31, 2023. In June 2023, Sanofi filed a revocation action attacking the validity of EP 3 666 797 in the

Munich Central Division of the UPC. In this action, a first instance decision invalidating this Amgen patent was issued in July 2024.

Amgen appealed, and this decision was reversed by the UPC Court of Appeal in November 2025. A request for rehearing of this

UPC appeal has been filed by Sanofi and Regeneron. A hearing in Amgen’s action for infringement (first instance) in the Munich

Local Division of the UPC will take place in November 2026.

Sanofi and Regeneron have also attacked the validity of the same EP 3 666 797 patent at the European Patent Office (EPO). The

first instance decision of the EPO found Amgen’s patent valid in May 2025. These proceedings are currently under appeal with a

decision expected in April 2026.

c) Other litigation

Plavix (clopidogrel) – Attorney General Action in Hawaii

In March 2014, the Hawaii Attorney General (AG) filed a complaint that sets forth allegations related to the sale and marketing of

and variability of response to Plavix. The Hawaii AG specifically alleged that Plavix had a diminished effect in patients of certain

genetic backgrounds and that Sanofi and BMS had failed to make an earlier disclosure of this information.

In February 2021, the Court issued its decision, imposing penalties in the total amount of $ 834 million against both Sanofi and

Bristol Myers Squibb (BMS), with $ 417 million being apportioned to each company. In June 2021, Sanofi and BMS appealed this

judgment. The appeal was transferred directly to the Hawaii Supreme Court. In March 2023, the Hawaii Supreme Court vacated

the judgment and ordered a new trial. A second trial was concluded in October 2023 and in 2024 a judgment was rendered

against the defendants for $ 916 million ( $ 458 million against Sanofi). Sanofi and BMS have appealed this decision to the Hawaii

Supreme Court. In May 2025, the parties agreed to settle the Hawaii action. Sanofi US paid $ 350 million pursuant to its settlement

agreement and Bristol-Myers Squibb paid $ 350 million pursuant to its separate settlement agreement. The appeal and the

underlying case were dismissed pursuant to the settlement. This matter is closed.

Plavix (clopidogrel) – Attorney General Action in Texas

On November 20, 2025, the Texas Attorney General (Texas AG) filed a complaint in Harrison County, Texas, against Sanofi and its

partner Bristol Myers Squibb (BMS). The suit alleges that Defendants failed to warn that Plavix has diminished or no effect for

certain patients, including those who have a genetic variation of a liver enzyme called CYP2C19 which is more prevalent among

minority patients. The lawsuit asserts that Defendants violated the Texas Deceptive Trade Practices Act and Texas’ Health Care

Program Fraud Prevention Act.

Plaintiffs seek civil penalties as well as recovery of claimed Texas Medicaid overpayments for Plavix. Sanofi and BMS are

responsible for the suit on a 50/50 basis under their partnership agreement. In addition, also on November 20, 2025, Sanofi and

BMS sued the Texas AG in Travis County, Texas, arguing that the Texas AG’s lawsuit violated their constitutional due process

SANOFI FORM 20-F 2025 F-89

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

rights. This suit seeks a declaratory judgment that the Texas AG’s case is unlawful and to enjoin the Texas AG suit from

proceeding.

Plavix (clopidogrel)-related litigation in France

On September 24, 2025, the Paris Court of Appeal ordered Sanofi to pay the CNAM approximately € 150 million in damages to

compensate for harm caused by its communication and promotional practices during five months between the end of 2009 and

early 2010, inhibiting the entry on the market of generics of its anticoagulant Plavix. In November 2025, Sanofi filed an appeal

before the French Supreme Court ( Cour de cassation ).

340B Drug Pricing Program in the United States

Sanofi is currently involved in several matters relating to the 340B drug pricing program in the US (a federal program that

requires drug manufacturers to offer certain products to certain “covered entities” at reduced prices). In 2021, Sanofi launched an

integrity initiative to combat fraud and abuse in the 340B program relating to covered entities’ use of unlimited contract

pharmacies. Under that initiative, Sanofi collects limited, de-identified, claims data on 340B-priced drugs dispensed by contract

pharmacies. In January 2023, the Third Circuit Federal Court of Appeals held that Sanofi’s 340B integrity initiative is not contrary

to law.

In 2024, Sanofi announced that it intended to implement an additional integrity initiative called the “Credit” or “Rebate” Model

whereby credits are provided to covered entities for the difference between the 340B price and initial price paid. When the US

Health Resources and Services Administration (HRSA) rejected Sanofi’s Credit Model, Sanofi filed suit. In May 2025, the court

ruled that the US government had not provided a sufficient explanation for rejecting Sanofi’s Credit Model and ordered HRSA to

conduct a further review, which is ongoing. The court also held that, although Section 340B does not categorically prohibit the

use of manufacturer rebates, it does allow HRSA to require preapproval of a manufacturer rebate program.

Eli Lilly, Bristol Myers Squibb, Novartis, and Kalderos appealed the court’s decision and oral arguments in those appeals, along

with a similar appeal by Johnson & Johnson, were held on November 17, 2025. The appeals are awaiting a ruling.

HRSA has also proposed a 340B Rebate Model Pilot Program, a program that would replace upfront 340B Program discounts

with retrospective rebates for select drugs. A federal district court preliminarily enjoined the 340B Rebate Model Pilot Program

and the First Circuit Court of Appeals has declined to stay that injunction.

ADR Proceedings in the United States

Sanofi is named in two (2) Active 340B Administrative Dispute Resolution (ADR) proceedings, one filed by University of

Washington/Harborview Medical Center in 2023 and one filed by Hudson Headwaters Health Network in 2024, both alleging that

Sanofi’s 340B Integrity Initiative caused “overcharges” under Section 340B. Sanofi previously responded to both filings and in

January 2026, separate 340B ADR Panels were assigned to review the two claims.

State Litigation in the United States

PhRMA and certain other manufacturers are challenging contract pharmacy laws passed by several states, including Arkansas,

Colorado, Hawaii, Kansas, Louisiana, Maine, Maryland, Minnesota, Mississippi, Missouri, Nebraska, New Mexico, North Dakota,

Oklahoma, Oregon, Rhode Island, Tennessee, Utah, South Dakota, West Virginia and Vermont. To date, these state laws have

largely survived these legal challenges, but most of the court rulings are currently under appeal.

Mosaic Health in the United States

In July 2021, Mosaic Health Inc. and Central Virginia Health Services (covered entities) filed a nationwide antitrust class action

complaint against Sanofi and three other manufacturers in the United States District Court for the Western District of New York.

Plaintiffs allege that Sanofi and the other defendants conspired to eliminate favorable 340B pricing, particularly with respect to

diabetes therapies. On September 2, 2022, the court granted Defendants’ motion to dismiss the complaint. On October 3, 2022,

plaintiffs filed a motion for leave to file a second amended complaint, which the court denied on February 1, 2024. Plaintiffs filed

an appeal and in August 2025, the Second Circuit Court of Appeal reversed and ordered the case remanded to the District Court.

Adventist Health System/West in the United States

In June 2023, Adventist Health System/West sued several drug manufacturing companies, including Sanofi-Aventis US LLC,

Sanofi US Services Inc. and Genzyme Corporation, alleging that the companies violated state and federal False Claims Acts

through overcharging for 340B Program drugs in violation of federal “penny pricing” policy. The manufacturers jointly moved to

dismiss, which was granted by the court in March 2024. Plaintiffs filed an appeal.

Antitrust investigation by the European Commission in France and Germany

On September 29, 2025, Sanofi, Sanofi Pasteur Europe and Sanofi Aventis Deutschland were the target of an investigation by

representatives of the European Commission (EC) who visited the premises of Sanofi in France and Germany in connection with

the seasonal flu vaccine space. The EC has subsequently provided Sanofi with a copy of the complaint filed by CSL Sequirus,

which gave rise to the investigation. CSL Sequirus alleges that Sanofi is guilty of disparagement of its Fluad product in certain

markets (primarily Germany) where Sanofi would hold a dominant position. The complaint requests interim measures to be

imposed against San ofi.

Preliminary investigation by the Parquet national financier in France

Sanofi used a financing arrangement offered by Société Générale as part of an acquisition transaction which happened more

than 10 years ago. This financing arrangement is now under investigation by the French National Financial Prosecutor’s Office

( Parquet national financier - PNF ). On November 25, 2025, Sanofi’s headquarters were visited by the authorities as part of this

investigation. The PNF is conducting a preliminary investigation related to allegations of money laundering, tax fraud and criminal

conspiracy.

d) Contingencies arising from certain mergers & acquisitions transactions

As a result of divestitures, Sanofi is subject to a number of ongoing contractual and legal obligations regarding the state of the

sold businesses, their assets, and their liabilities, some of which may be subject to dispute.

Aventis CropScience Retained Liabilities

The sale by Aventis Agriculture SA and Hoechst GmbH (both legacy companies of Sanofi) of their aggregate 76 % participation in

Aventis CropScience Holding (ACS) to Bayer and Bayer CropScience AG (BCS), the wholly owned subsidiary of Bayer which holds

the ACS shares, was effective on June 3, 2002. The Stock Purchase Agreement (SPA) dated October 2, 2001, contained

customary representations and warranties with respect to the sold business, as well as a number of indemnifications subject to

limitation periods and caps, in particular with respect to environmental liabilities for which some outstanding claims from Bayer

remain unresolved.

Infraserv Hoechst Retained Liabilities

By the Asset Contribution Agreement dated December 19/20, 1996, as amended in 1997, Hoechst contributed all land, buildings,

and related assets of the Hoechst site at Frankfurt Hoechst to Infraserv GmbH & Co. Hoechst KG. Infraserv Hoechst undertook to

indemnify Hoechst against environmental liabilities at the Hoechst site and with respect to certain landfills. As consideration for

the indemnification undertaking, Hoechst transferred to Infraserv Hoechst approximately € 57 million to fund reserves. In 1997,

Hoechst also agreed it would reimburse current and future Infraserv Hoechst environmental expenses up to € 143 million . As a

former operator of the land and as a former user of the landfills, Hoechst may ultimately be liable for costs of remedial action in

excess of this amount.

D.30. Income tax expense

Sanofi has elected for tax consolidations in a number of countries, principally France, Germany, the United Kingdom and the US.

The table below shows the allocation of income tax expense between current and deferred taxes:

(€ million)	2025	2024	2023 (a)
Current taxes	( 3,437 )	( 2,152 )	( 2,251 )
Deferred taxes	2,394	948	1,234
Total	( 1,043 )	( 1,204 )	( 1,017 )
Income before tax and investments accounted for using the equity method	6,175	6,698	6,251

(a) 2023 comparative figures were re-presented on a consistent basis from the date of the classification of Opella as a discontinued operation (2024).

The difference between the effective tax rate and the standard corporate income tax rate applicable in France is explained as

follows:

(%)	2025	2024	2023 (a)
Standard tax rate applicable in France	25.8	25.8	25.8
Difference between the standard French tax rate and the rates applicable to Sanofi (b)	( 11.8 )	( 13.3 )	( 15.3 )
Revisions to tax exposures and settlements of tax disputes	5.1	2.8	3.1
Fair value remeasurement of contingent consideration	( 0.1 )	—	0.1
Other items (c)	( 2.1 )	2.7	2.6
Effective tax rate	16.9	18.0	16.3

(a) 2023 comparative figures were re-presented on a consistent basis from the date of the classification of Opella as a discontinued operation (2024).

(b) The difference between the French tax rate and tax rates applicable to foreign subsidiaries reflects the fact that Sanofi has operations in many

countries, most of which have lower tax rates than France. This line includes a tax expense of € 40 million for the year ended December 31, 2025, and of

€ 58 million for year ended December 31, 2024, representing the estimated impact of Pillar Two; the 2025 figure also includes a non-recurring tax impact

of € 178 million for the temporary exceptional surcharge under the 2025 French Finance Act.

( c) In 2025, the ''Other items'' line includes changes in provisions against deferred tax assets, partially offset by (i) the impact of changes to tax rates in

Germany and the US and the net tax effect of taxable temporary differences associated with holdings in Sanofi subsidiaries. In determining the amount

of the deferred tax liability for 2025 , 2024 and 2023 , Sanofi took into account changes in the ownership structure of certain subsidiaries .

For the periods presented, the amount of deferred tax assets recognized in profit or loss that were initially subject to impairment

losses at the time of a business combination is immaterial.

D.31. Share of profit/loss from investments accounted for using the equity method

The line item Share of profit/(loss) from investments accounted for using the equity method showed a net loss of € 155 million

in 2025, including a loss of € 310 million on the equity-accounted investment in the associate OPAL JV Co ( see Note D.6),

compared with a net gain of € 60 million for 2024 and a net loss of € 136 million for 2023 .

with IAS 24 (see Note D.6.).

(c) This line mainly includes revenues received under agreements for Sanofi to provide manufacturing services to third parties.

(d) Consumer Healthcare activities not transferred on the effective date of loss of control of Opella. These are primarily (i) hospital sales of Opella products

in China, the transfer of which will be finalized no earlier than 2028; (ii) sales made by the dedicated entity Opella Russie , of which Sanofi continues to

hold the capital (Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in connection with the

separation, the parties reserving the right to discuss the transfer of that entity during the term of the distribution agreement); and (iii) sales of the Gold

Bond product range, which are continuing in the US through the retained subsidiary Gold Bond LLC (holder of the associated worldwide property

D.35. Segment information

T he segment information presented by Sanofi consists of a single operating segment: Biopharma.

The Biopharma operating segment comprises commercial operations and research, development and production activities

relating to the Specialty Care, General Medicines, and Vaccines franchises plus support and corporate functions, for all

geographical territories. It also includes revenues generated from the manufacture of Consumer Healthcare products invoiced to

Opella Healthcare SAS (Opella), which constitutes a related party with effect from April 30, 2025, the deconsolidation date,

corresponding to the closing of Sanofi's sale of a controlling stake of approximately 50% in Opella to Clayton, Dubilier & Rice

(CD&R) (for more information, see “Item 4. Information on the Company — B. Business overview — B.3 Opella”). Those revenues,

which before the deconsolidation date represented intragroup transactions classified within continuing operations, are

presented within Other revenues in the income statement. The Biopharma operating segment also includes the purchase price

of Biopharma products manufactured by Opella.

The “Other” category comprises primarily, but not exclusively, Consumer Healthcare activities not transferred on the effective

date of loss of control of Opella. These are primarily (i) hospital sales of Opella products in China, the transfer of which will be

finalized no earlier than 2028; (ii) sales made by the dedicated entity Opella Russie, of which Sanofi continues to hold the capital

(Sanofi is continuing to distribute Opella products in Russian territory under a distribution agreement signed in connection with

the separation, the parties reserving the right to discuss the transfer of that entity during the term of the distribution agreement);

and (iii) sales of the Gold Bond product range, which are continuing in the US through the retained subsidiary Gold Bond LLC

(holder of the associated worldwide property rights).

2023 comparative figures were re-presented on a consistent basis from the date of the classification of Opella as a discontinued

operation (2024).

D.35.1. Segment results

Sanofi reports segment results on the basis of “Business operating income”. This indicator is used internally by Sanofi’s chief

operating decision maker to measure the performance of the operating segment and to allocate resources.

“Business operating income” is derived from Operating income , adjusted as follows:

• amortization and impairment losses charged against intangible assets (other than software and other rights of an industrial or

operational nature), are eliminated;

• fair value remeasurements of contingent consideration relating to business combinations (IFRS 3) or business divestments,

and presented within the line item Fair value remeasurement of contingent consideration , are eliminated;

• expenses arising from the remeasurement of inventories following business combinations (IFRS 3) or acquisitions of groups of

assets that do not constitute a business within the meaning of paragraph 2b of IFRS 3, are eliminated;

• amounts reported within the line items Restructuring costs and similar items are eliminated;

• other gains and losses including gains and losses on major divestments, presented within the line item Other gains and losses,

and litigation , are eliminated;

• other costs and provisions related to litigation, presented within the line item Other gains and losses, and litigation , are

eliminated;

against various research and development projects (including a € 239 million loss resulting from the decision taken in February 2025 to discontinue a

Phase 3 clinical study investigating a vaccine candidate to prevent invasive E.coli disease), partially offset by (ii) impairment loss reversals recognized in

D.36. Information related to Opella, presented within assets held for sale and

discontinued operations

On April 30 2025, the Opella transaction was closed (see Note D.1.) triggering loss of control, and resulting in the derecognition of

all assets and liabilities of Opella subsidiaries. As of December 31, 2024, all Opella assets and associated liabilities were classified as

held for sale (see Note D.8.), in accordance with IFRS 5.

In accordance with IFRS 5, the Opella held for sale asset group, and the related liabilities, have been measured at the lower of

carrying amount and fair value less costs to sell. This valuation did not result in the recognition of any impairment.

The table below details the main items presented within Net income from discontinued operations :

(a) In 2025, these lines include the net sales, other revenues and operating income of Opella until the date of loss of control (see Note D.1.).

(b) In 2025, this line includes an expense of € 108 million related to the tax impact on the gain arising on the loss of control of Opella (see Note D.1.).

Net income from the Opella discontinued operation was € 274 million lower in 2024 than in 2023. This year-on-year change

reflects in particular the acceleration in 2024 of the transformational project to create the standalone Opella entity - transaction

costs incurred in 2024 in respect of the proposed Opella transfer - and changes in gains from asset divestments within the Opella

scope between the two periods.

In addition, net income from the Opella discontinued operation for the year ended December 31, 2024 includes a net tax expense

of € 122 million relating to the tax cost of the legal restructuring of the Opella scope. For the year ended December 31, 2023, net

income from the Opella discontinued operation includes a € 365 million deferred tax liability recognized in respect of investments

in consolidated entities in light of the proposed separation of the Opella business.
