1.1.1 ENI ACTIVITIES: THE VALUE CHAIN

Eni is a global energy company with a high technological content, engaged in the entire value chain: from the exploration, development and extraction of oil and natural gas, to the generation of electricity from cogeneration and renewable sources, traditional and biorefining and chemicals, and the development of circular economy processes. Eni extends its reach to end markets, selling gas, electricity and products to local markets and to retail and business customers to whom also offers services of energy efficiency and sustainable mobility. Consolidated expertise, technologies, geographical and source diversification, alliances for development and innovative business and financial models are Eni levers to continue to generate value, effectively responding to the challenges of the energy trilemma (environmental sustainability, energy security and accessibility). In particular, Eni is committed to become a leading company in the production and sale of decarbonised energy products and services, increasingly customer-oriented. The Eni Carbon Neutrality by 2050 strategy is based on an industrial transformation plan that envisages the use of technological solutions that are already available and economically sustainable, such as:

Gradual growth of the gas component as an energy source that bridges the gap in the transition, flanked by investments to reduce emissions;
Bioenergy through the development of biomethane and biofuels, with an increasing input of raw material from waste and from an integrated agri-feedstock production chain not in competition with the food chain;
Renewables through increased capacity and integration with the retail business;
Carbon Capture Storage (CCS) through the development of dedicated CO2 storage hubs for hard-to-abate emissions from Eni and third-party industrial sites;
Gradual increase in the production of new energy vectors, including hydrogen.

Using these solutions at scale will be joined by research on breakthrough technologies, such as magnetic confinement fusion, that can contribute to transforming the energy sector. Residual emissions, i.e. those that cannot be reduced due to technical and economic restrictions, will be offset through the use of high-quality carbon offsetting, mainly deriving from Natural Climate Solutions.

At December 31, 2022, Eni controlled 401 companies in Italy and abroad9.

⁹ This refers to consolidated subsidiaries.

INFORMATION ON THE OWNERSHIP STRUCTURE

Eni's values are set forth in the Eni Code of Ethics

1.2 Principles and values. The Code of Ethics

Integrity and transparency are the principles that guide Eni's action in formulating a management and control structure that is suited to its size, complexity and operating structure, in adopting an effective Internal Control and Risk Management System, and in communicating with shareholders and other stakeholders, also by reviewing and updating the information on its website.

These values and principles are set forth in the Eni Code of Ethics, as updated and approved by the Board of Directors on March 18, 2020, which replaces the previous Code approved by Eni's Board of Directors on November 23, 2017. The Code of Ethics is published on Eni website (https://www.eni.com/en-IT/about-us/governance/code-of-ethics.html).

The Code of Ethics addresses the members of the Corporate management and control bodies, all Eni's employees, as well as those who work with, on behalf or in the interest of Eni; all are required to uphold, in the context of their own functions and duties, the principles set out in the Code of Ethics.

The Code of Ethics is a document designed for easy use, providing clear indications on the rules of conduct to be adopted and practical examples. The Code is enriched with important elements of innovation, including the correlation of each principle with the United Nations Sustainable Development Goals (SDGs), to make the Code consistent and complementary to Eni's mission, of which the SDGs are a fundamental element.

In particular, Eni's values are expressed in the Code of Ethics in form of commitments that the company takes and which in turn are translated into standards of conduct for people, so that the principles contained therein form a practical guide for corporate operations.

For that purpose, the Code of Ethics is available in 12 languages. It has been distributed widely and is promoted through a range of initiatives, including special training courses.

The Code of Ethics contains unavoidable general principles and is a key element of the anticorruption framework. Furthermore, despite having independent relevance, it is the fundamental reference principle of Model 231 – identifying the essential ethical values for the purposes of preventing predicate offenses – as well as part of the "General framework of the regulatory system", which inspires the provisions contained in company regulations.

The promotion and training activity on the Code of Ethics is the responsibility of the Integrated Compliance function, which also ensures implementation support by involving the competent functions, while reporting of potential violations is taken back in the whistleblowing procedure, governed by the specific regulations10.

The Code of Ethics and amendments are approved by the Board of Directors of Eni SpA, on the proposal of the Chief Executive Officer in agreement with the Chairman, having heard the opinion of the Board of Statutory Auditors and the Control and Risk Committee.

The Code of Ethics also applies to all direct or indirect subsidiaries, both in Italy and abroad.

The representatives designated by Eni on the corporate bodies of associated companies, consortia and joint ventures promote the principles and contents of the Code within their respective spheres of responsibility.

¹⁰ For more information, please refer to the section on the "Procedure for whistleblowing reports received, including anonymously, by Eni SpA and by its subsidiaries in Italy and abroad" of this Report.

The Board defined the mandatory principles of Eni's Corporate Governance system

1.3 Principles of Corporate Governance

The Board of Directors defined the inalienable principles of Eni's Corporate Governance system, identifying integrity and transparency as the founding principles of its system and stating its commitment to:

adopting measures that ensure correct handling of any situation that may involve a conflict of interest, even potential, while safeguarding the rights of and relations with its stakeholders and providing complete, timely, clear and correct information, ensuring shareholders have equal access to information;
pursuing the best Corporate Governance practices, including through comparison with the best Italian and foreign governance models and, in particular, with the principles issued by the most representative institutions and associations;
promoting its Corporate Governance principles outside by encouraging observations and introducing new ideas, in particular through participation in institutional and sector working groups and by promoting relevant initiatives;
promoting and maintaining an adequate, effective and efficient Internal Control and Risk Management System.

In performing its management and coordination activities, Eni acts in accordance with the principles of sound corporate and entrepreneurial management, of the legal and managerial independence and thus the specific interests of the individual companies, in particular of those listed companies and/or subject to unbundling regulations, the interests of other shareholders, the confidentiality obligations that safeguard the commercial interests of the companies and that guarantee the correct application of market abuse regulations and the applicable regulations, including local regulations in the case of foreign companies.

More specifically, among the aims pursued, actions designed to ensure an adequate, effective and efficient Group Internal Control and Risk Management System are of fundamental importance, in addition to compliance with the rules the Company is subject to in its role as parent company.

1.4 Responsible and sustainable approach and dialogue with stakeholders

A responsible and sustainable approach is part of every business aspect of Eni and represents its method of operating for value creation over the medium and long-term for the Company and for all stakeholders. This distinctive approach allows operating in the complex current scenario while responding to the most crucial challenge of the energy sector: providing efficient and sustainable access to energy for all, while fighting the effects of climate change by reducing climate changing emissions related to business activities and the entire life cycle of the energy products sold. In this context, Eni is committed to promoting a just transition that prioritises people, that is effective and incisive, while contemplating the adoption of different solutions with varying gradualness, based on the specific nature of the contexts and internal restrictions, and that makes it possible to achieve the goal of zero net emissions by 2050. The distinctive approach is also based on sharing the social and economic benefits with workers, communities, suppliers and customers in an inclusive, transparent and socially equitable manner, with the awareness of the importance of the social dimension of the ambitious path taken. Eni is working to ensure that the process of decarbonisation will offer opportunities to convert existing activities and develop new production chains with significant employment and economic growth opportunities for the countries where Eni operates, including in consideration of their varying levels of development. In this respect, the new 2023-2026 Strategic Plan has defined specific actions to guide the transformation process of Eni's business, with initiatives aimed at developing professional experience for the internal needs for skills that support the energy transition. As

Eni operates under a logic of value creation over the medium and long-term for the Company and all the stakeholders

part of the "transition out" activities or the transformation processes, Eni is committed to prioritising worker reskilling and upskilling programmes with the aim of doing its best to support their relocation into new or transformed activities (in the context of the Company or other companies). As regards local development initiatives, the new Plan seeks to strengthen communities with a particular focus on more complex and vulnerable contexts, particularly in the sectors of access to energy, economic diversification, education and professional training, improving people's quality of life and furthering their resilience mechanisms including with respect to the transformations that the energy transition entails11.

The Eni's mission and the contribution to achieving the SDGs

The path is also confirmed in Eni's mission – approved by the Board of Directors in September 2019 – which organically integrates the 17 UN Sustainable Development Goals (SDGs) to which Eni intends to contribute12 aware that business development can no longer be separated from them. In this sense, from the initial stages of definition and development, the business projects are measured against the SDGs in order to quantify their contribution in the respective country and to guide their project decisions. This measurement, launched in 2020 and applied to several case studies, will be systematically rolled out.

This cultural change already belongs to Eni's people, and provides a continuous innovation drive, leveraging diversity as a universal development driver, respect for and promotion of human rights integrity and transparency in managing its business, protection of the environment.

Achieving the SDGs requires unprecedented collaboration between the public and private sectors. Accordingly, Eni is committed to identifying and building alliances with committed partners (International Organisations, Italian and European institutions, development banks, private sector, cooperation bodies and agencies, civil society and religious organisations) with authoritative technical competence, prestige and reliability as well as presence and impact capacity in the Countries in which it operates. In this way, synergies and sharing know-how, expertise and assets can fuel the growth of the communities and Countries, within a framework of economic diversification, education and training, access to energy and water, health and hygiene promotion.

This action is testified to by collaborations launched by Eni with United Nations agencies such as UNDP, UNIDO, UNESCO and UNICEF, national cooperation agencies such as AICS, USAID and SETAB, financial institutions such as World Bank, CDP and Standard Bank, civil society organisations such as ADPP, AVSI, Banco Alimentare, CUAMM, GHACCO, Elsewedi Electric Foundation, Fondazione E4Impact, Istituto Superiore Don Bosco of Maputo, SACA, TechnoServe, and VIS13, and the private sector such as CNH Industrial and Iveco Group. In 2022, Eni's continued its participation in the UN Global Compact, the largest global initiative on corporate sustainability, confirming its constant commitment in favour of the United Nations principles for responsible business. After signing the Women's Empowerment Principles in 2021, in 2022 Eni participated in Target Gender Equality Accelerator, a programme dedicated to the private sector and coordinated by UN Global Compact with the support of UN Women.

The role of the Board of Directors

Eni has also joined the Extractive Industries Transparency Initiative (EITI), a multi-stakeholder initiative aimed at promoting the responsible management of natural resources and

¹¹ Furthermore, in 2022 the first institutional capacity building initiative took place, aimed at ministerial officers in Kenya and Rwanda, for the promotion of renewable energies and to accelerate the energy transition, in particular in countries that export fossil fuels, according to the three-year agreement signed by Eni and the International Renewable Energy Agency (IRENA).

strengthening the governance of the extractive sector, also supporting its international activities in 2022 and contributing to the implementation of EITI standards at local level. Eni Board of Directors plays a central role upon the proposal of the Chief Executive Officer, in the definition of the strategic guidelines and objectives of the Company and the Group, pursuing the sustainable success and monitoring their implementation. In this area, the Board of Directors, upon the proposal of the Chief Executive Officer, examines and/or approves strategic initiatives and targets, the portfolio of Eni top risks, including climate change, the Short-Term and Long-term Incentive Plan14, with targets linked to the decarbonisation strategy for the Chief Executive Officer and management, relevant projects and their progress on a six-monthly basis, with sensitivity to carbon pricing and strategic agreements.

The sustainability of our business in the medium to long-term and the associated challenges, as connected with energy transition and possible decarbonisation scenarios, are the central themes of Eni's Long-Term and Strategic Plan. In March 2022, Eni relaunched its objectives to reduce GHG emissions, with new short and medium-term targets that have accelerated its path towards carbon neutrality by 2050, confirming Eni's commitment to further align its reduction trajectory to low-carbon scenarios. The new 2023-2026 Strategic Plan and medium/long-term Plan, approved by the Board of Directors on February 22, 2023, confirms the objectives to reduce emissions and the industrial transformation plan that will lead Eni to complete decarbonisation of its energy processes and products by 2050.

On sustainability issues, the Board of Directors is supported by a Board Committee, called the Sustainability and Scenarios Committee ("SSC"), which was established in 2014 by the Board. Among other tasks15, the Committee periodically examines issues concerning the integration of strategy, development scenarios and the long-term sustainability of the business, analysing scenarios for the preparation of the Strategic Plan.

Thanks to a growing commitment to transparency and the business model Eni built over the last nine years to create sustainable value in the long-term, Eni share achieved or maintained leadership performance in the most popular ESG ratings and confirmed its presence in the main ESG indices16.

Eni commitment on respect and promotion of Human Rights

In 2022 Eni continued with the path that led to the approval of the Eni Declaration on respect for human rights by Eni's Board of Directors in December 2018, reinforcing incentives related to performance on Human Rights within the targets assigned to the various managerial levels and implementing the management model aimed at ensuring the performance of the due diligence process in accordance with the United Nations Guiding Principles on Business and Human Rights (UNGP) and the OECD Guidelines for Multinational Enterprises. In December 2022, the Sustainability and Scenarios Committee examined the issue of respect for human rights as part of the just transition. With a view to constantly improving its approach and the accessibility of this information, Eni has published the fourth edition of the "Eni for Human Rights" report, which describes the management model adopted on the subject and reports on the activities carried out in recent years, using the UNGP Reporting Framework to report on commitments and results achieved. In 2022, the focus report "Eni and the people-centred transition" was also published, which presents Eni's commitment and describes key just transition initiatives for Eni's workers, suppliers, communities and customers, including with the support of dedicated case studies. Furthermore, as of November 2022, Eni is a "full member" of the Voluntary Principles Initiative, (VPI), having successfully completed the admission process. VPI is an initiative made up of governments, international organisations and companies, which promotes the implementation of the Voluntary Principles on Security

and Human Rights, aimed at supporting and guiding companies in the management of risks of human rights violation in security activities.

Human rights impact studies were also carried out on the most relevant projects, identified using a risk-based approach, with particular reference to agribio-feedstock projects launched in Congo and Kenya in 2022. These projects were also subject to an analysis of their socioeconomic impacts. In 2022, specific interfunctional working groups were also established to monitor regulatory changes in relation to human rights and to analyse their implications for Eni, with particular reference to the EU's proposed Corporate Sustainability Due Diligence Directive and the proposed Regulation that bans products obtained using forced labour on the EU market.

Other activities in the field of human rights include several projects, previously launched in 2021, associated with the corporate regulatory instrument, attached to the Management System Guideline "Internal Control and Risk Management System", called "Eni against violence and harassment at work". In particular, training and information activities were carried out, with the assignment of specific managerial objectives to all Eni managers. Lastly, planning of the training course aimed at all Eni personnel was completed and is expected to be delivered in 2023. Furthermore, note that the regulatory instrument adopted by Eni against violence and harassment at work received an award at the LC Sustainability Awards 2022 as an expression of Eni's forward-looking and ambitious approach to ethics and compliance. Lastly, the responsible contracting activity continued as part of Human Rights Compliance.

Continuing the process of integrating financial and non-financial disclosure, started in 2010 by Eni, the Management Report in the Annual Report has been supplemented since 2017 with a specific section entitled "Consolidated Disclosure of Non-Financial Information" (hereinafter the NFI) as provided for under Legislative Decree No. 254/201617. The NFI, which is prepared on the basis of the Global Reporting Initiative (GRI) reporting standard, was approved by Eni Board of Directors and subject to limited assurance by the audit firm engaged to perform the statutory audit of Eni's financial statements (PWC), in accordance with the provisions of law and the appropriate professional standards for assurance on non-financial information (ISAE 3000). Sustainability reporting

In addition to the NFI, Eni continues to publish a report on corporate sustainability, prepared on voluntary basis, called "Eni for", which has been prepared and presented at the Shareholders' Meeting since 2006, after approval by the Board of Directors. This document reinforces Eni's commitment to the energy transition and Eni's contribution to the SDGs. It illustrates Eni's commitment to achieving Carbon Neutrality by 2050 on the basis of the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD) of the Financial Stability Board.

Since 2019, Eni has been included among the 10 Top Performers in the world for its sustainability reporting in the document "Reporting Matters 2022" published by the World Business Council for Sustainable Development (WBCSD), which evaluated over 150 world leading companies in various sectors.

Eni considers stakeholder engagement to be a fundamental lever for the creation of long-term value18. Operating in 62 countries with different socio-economic contexts, an understanding of the expectations of all stakeholders and the sharing of decisions are strategic factors for maintaining relations based on mutual trust, transparency and integrity. The dialogue with stakeholders

This attitude responds to the Recommendation of the Corporate Governance Code, according to which the Board of Directors must also promote, in the most appropriate forms, dialogue with the stakeholders relevant to the Company and is based on the principles and guidelines expressed by the Board itself in Eni's Code of Ethics19.

The company application "Stakeholder Management System" (SMS), operational since 2018, is dedicated to "mapping" stakeholders by activities and new projects of all Eni business lines. Stakeholders are analysed on the basis of their relevance and vulnerability in the context and their disposition towards the company's activities. SMS also collects all the documentation relating to the relationship with individual stakeholders in the territories where Eni operates, including requests and grievances, and the related response actions undertaken. The system supports the knowledge of contexts, including thanks to the mapping of the areas surveyed by UNESCO as sites of particular cultural and/or natural interest (World Heritage Sites, WHS).

With these tools, SMS makes it possible to understand the main issues of interest of stakeholders and the potential impacts on Human Rights. This all contributes to the definition of the stakeholder engagement strategies in the territories of operation, the evaluations of company reputation with the various categories of stakeholders and the assessment and monitoring of "Relations with Local Stakeholders" operational risk; this risk is rated as Eni's Top Risk and is therefore subject to periodic reporting to the Board of Directors as part of Eni's Integrated Risk Management Model.

In 2022, updated versions were issued of the corporate regulatory instruments attached to the Management System Guideline "Responsible and Sustainable Business" regarding Stakeholder Engagement and the Grievance Mechanism respectively.

1.5 Eni's Corporate Governance initiatives

Eni is committed to building a corporate governance system founded on excellence in our open dialogue with the market. Accordingly, the Company has pursued a number of initiatives for improving its own system and that of the nation, focusing heavily on communication with its stakeholders and demonstrating an ongoing commitment to helping shareholders exercise their rights effectively.

More specifically, in 2011 Eni provided a contribution to the debate on the corporate governance of listed Italian companies, based on the analysis of foreign best practices that are not yet established in the national system and to which Eni pays particular attention due to the international scope of its business. The results of the analysis, filtered through the Company's experience, led to the drafting of 35 proposals (regulatory and self-discipline) to improve the efficiency of the Italian system. A large portion of the proposals was incorporated as recommendations or comments in the 2011 edition of the Corporate Governance Code.

Following this initiative, in 2018 and 2019 the competent corporate functions, also with the support of an external consultant, carried out some in-depth analysis and engaged in dialogue with the market on aspects of possible interest with a view to the continuous improvement of Eni's governance model, to seize opportunities arising from studies and experience gained in the international context. Dialogue with the market on governance

In particular, possible future evolutions of the Company's governance system were investigated by means of a survey and meetings of the Chairman of the Board of Directors with Eni's leading shareholders and proxy advisors.

¹⁹ For more information on dialogue with stakeholders, please refer to the section "Stakeholder Engagement Activities" in the 2022 Annual Report.

This showed a substantial and widespread appreciation of Eni's governance system, which investors appear to consider adequate and efficient, without excluding the possibility of introducing governance solutions aligned with international models also adopted by Eni's peers.

During 2020, Eni participated in initiatives promoted by national and international bodies and associations, including the Enacting Purpose Initiative, promoted by the Saïd Business School of the University of Oxford, to explore the issue of the Company's purpose in terms of sustainability.

Furthermore, on December 23, 2020, Eni's Board of Directors resolved to adopt the Corporate Governance Code, which applies from January 1, 2021.

In 2021 Eni participated in working groups for the in-depth study of issues related to the application of the new Code, including that of the Observatory on engagement policies with shareholders, established by Assonime (the Association of Italian joint stock companies) to offer a permanent forum for discussion between listed companies called upon to define a policy of dialogue with shareholders, as required by the Corporate Governance Code. The indepth study of the issue, also through the analysis of engagement policies adopted by institutional investors and asset managers as well as by representative trade associations, led to the development of a policy for dialogue with shareholders, approved on March 8, 2022 by Eni's Board of Directors, upon the proposal of the Chairman, in agreement with the Chief Executive Officer20.

In 2022, Eni participated in working groups for in-depth analysis of topics subject to European legislation such as corporate sustainability reporting and sustainability due diligence, as well as in-depth studies on Say on Climate. In particular, in the occasion of the Shareholders' Meeting on May 11, 2022, in continuity with the previous year, a message was published by the Chairman and the Chief Executive Officer about the climate transition, which asked shareholders to express, through the designated representative, their opinions on the climate strategy outlined in the document. This message received positive feedback from the Climate Action 100+ coalition.

Lastly, consideration was given to possible changes to the corporate model and, including on the basis of dialogue held with shareholders, it was agreed to maintain the current model.

Corporate governance initiatives, as well as the adoption of application modalities that go beyond the recommendations of the Corporate Governance Code, will be described in more detail further on in this Report.

1.6 Corporate Governance Model

1.6.1 THE CORPORATE GOVERNANCE MODEL OF ENI SPA

Corporate Governance structure is based on the traditional Italian model, which – respecting the duties of the Shareholders' Meeting – assigns the strategic management of the Company to the Board of Directors, the heart of the organisational system, and supervisory functions to the Board of Statutory Auditors.

The statutory audit is carried out by an Audit Firm appointed by the Shareholders' Meeting.

In accordance with the By-laws, the Board of Directors appointed a Chief Executive Officer (hereinafter "CEO") to manage the Company, while reserving decisions on certain issues

Eni adopts the traditional management and control model

²⁰ For more information, please see the "Policy for managing dialogue with investors" section in this Report.

exclusively to itself. The CEO is therefore the main person responsible for the management of the Company, apart from those tasks reserved to the Board. On June 4, 2020 (with effect from July 1, 2020), the Board also appointed, pursuant to the By-laws, two Chief Operating Officers responsible for the Natural Resources and Energy Evolution business groups.

The Board of Directors gave its Chairman a major role in internal controls21. The Board also decided that the Chairman will, in accordance with the By-laws, be legal representative of the Company, responsible for managing institutional relationships in Italy, together with the CEO. The Chairman of the Board of Directors was also granted the powers, provided for by the Bylaws, for the identification and promotion of integrated projects and international agreements of strategic importance, shared with the CEO.

The model therefore makes a clear separation between the functions of the Chairman of the Board of Directors and those of the CEO, both of whom are empowered to represent the Company, in accordance with Art. 25 of the By-laws.

The Board of Directors has created four internal Committees having consulting and advisory functions: the Control and Risk Committee, the Remuneration Committee, the Nomination Committee and the Sustainability and Scenarios Committee. These Committees report to the Board at every meeting, through their respective Chairmen, on the most significant matters that they have addressed22.

Other key players in the Eni Governance model include:

the Officer in charge of preparing financial reports (Financial Reporting Officer), that the Board of Directors has identified, starting from August 1, 2020, in the Head of the Accounting and Financial Statements function of the Company;
the 231 Supervisory Body, appointed by the Board and composed by one internal member (identified as the Head of Internal Audit), the Chairman of the Board of Statutory Auditors and 3 external members, including the Chairman.

For more information on the Financial Reporting Officer and the 231 Supervisory Body, please see the specific sections of this Report.

Certain organisational and managerial decisions highlighted in this Report, including the designation of the Board of Statutory Auditors as the Audit Committee, were made to achieve compliance with US regulations, to which the Company is subject as a NYSE-listed company23.

The following chart represents the Company's governance structure as of December 31, 2022:

²¹ For more information, please refer to the section devoted to the Chairman in the chapter "Internal Control and Risk Management System" of this Report.

For more information, see the section of this Report on the Management System Guideline "Corporate Governance for Eni companies".

2. Information on the ownership structure26

2.1 Share capital structure, significant shareholdings and shareholders' agreements

Eni's share capital is made up of ordinary registered shares. The shares are indivisible and each one grants the holder the right to one vote. Holders of Eni shares have the right to vote in the Company's ordinary and extraordinary Shareholders' Meetings, and exercise the corporate and property rights given them under the laws in force, subject to the limits specified by the latter and by the Company's By-laws.

At December 31, 2022 the Company's share capital amounted to €4,005,358,876 — fully paidup — and comprises 3,571,487,977 ordinary shares without par value.

The Company's shares have been listed on Euronext Milan managed by Borsa Italiana SpA since November 1995. Also in 1995, Eni issued an American Depositary Receipts (ADR) programme for the US market. An ADR consists of a share certificate representing foreign company shares traded on stock exchanges of the United States. Each Eni ADR represents two ordinary shares and is traded on the New York Stock Exchange27.

Eni is therefore subject to the control of the Ministry of the Economy and Finance, which has enough votes to exercise a dominant influence in the ordinary Shareholders' Meeting of the Company, through stakes held directly in the Company (with 4.41%) and indirectly through Cassa Depositi e Prestiti SpA (CDP SpA), a company controlled by the Ministry (with 26.21%).

But Eni is not subject to the management and coordination of the Ministry of the Economy and Finance28 or of CDP SpA, pursuant to Art. 2497 of the Italian Civil Code, nor is the Company aware of any agreements between shareholders, pursuant to Art. 122 of the Consolidated Law on Financial Intermediation.

The following table shows the percentage of Eni's share capital owned, at March 16, 2023, directly or indirectly by shareholders or persons whose declared holdings exceed a major holding threshold pursuant to Art. 120 of the Consolidated Law on Financial Intermediation and the Consob Issuers Regulation. This threshold is updated based on information available to the Company.

²⁶ Information on the ownership structure is provided in accordance with the provisions of Art. 123-bis, first paragraph, of the Consolidated Law on Financial Intermediation. With reference to:

^• the mechanism for the exercise of voting rights in any employee share scheme where voting rights are not exercised directly by the employees, as specified in letter e) of the above-mentioned regulation; please note that the Company does not provide employee share schemes. With reference to the equity-based incentive plans in place, please refer to the Eni's Report on remuneration policy and remuneration paidavailable at www.eni.com;

^• rules that apply to the appointment and replacement of Directors, as specified in letter l) of the above-mentioned regulation, please refer to the paragraph "Appointment", of the section "Board of Directors";

^• amendments to the By-laws, as specified in letter l) of the above-mentioned regulation; please refer to the paragraph "Shareholders' Meeting and rights". ²⁷ For more information on the ADR program, please refer to the Investors section of Eni website.

²⁸ Art. 19, paragraph 6, of Italian Decree Law No. 78/2009, ratified by Law No. 102/2009, specifies that the reference to management and coordination activity contained in Art. 2497, first paragraph, of the Italian Civil Code must be interpreted with reference to the fact that "entities" refers to "collective legal subjects other than the State having shareholdings in the Company in the context of their entrepreneurial activity, or for economic or financial purposes".

Controlling shareholders	Number of shares	% of total ordinary shares
Ministry of the Economy and Finance	157,552,137	4 411
CDP SpA	936.179.478	26.213
Total	1,093,731,615	30.624

No changes had been reported at March 16, 2023.

The following is a graphical representation of the share capital structure and the distribution of shares by amount and geographical area, based on the registered share owners who received the second tranche of the payment instead of the dividend for 2022 made by intermediaries (ex-dividend date of November 21, 2022 - record date of November 22, 2022 payment date of November 23, 2022)29.

²⁹ Following purchases made during the company's 2022 Share Buyback programme, considering the Treasury shares already in the portfolio and the assignment of ordinary shares to Eni managers, after completion of the vesting period provided for in the "2017-2019 Long-Term Incentive Plan" approved by the Shareholders' Meeting on April 13, 2017, Eni held 226,097,834 treasury shares equal to 6.33% of share capital. The details of the Company's Share Buyback programme are available at the link: https://www.eni.com/en-IT/about-us/governance/shareholders.html.

INFORMATION ON THE OWNERSHIP STRUCTURE

3% holding and voting limit provided by law and By-laws

2.2 Shareholding limits and restrictions on voting rights

Pursuant to Art. 6.1 of the By-laws, in accordance with the special provisions specified in Art. 3 of Decree-Law No. 332 of 1994, ratified by Law No. 474 of 199430 (Law No. 474/1994), under no circumstances whatsoever may any party directly or indirectly hold more than 3% of the share capital. Exceeding these limits shall lead to a suspension of the exercise of voting rights or any other rights (except property rights) related to the shares exceeding the aforementioned limit, but leaving the property rights for such shares unchanged.

Therefore, while formally placing a limit on share ownership, in reality the rule restricts the exercise of voting rights and any other rights except property rights related to shares exceeding 3% of the share capital.

For the purposes of calculating the shareholding limit (3%), shares held through trustees and/or intermediaries are also taken into account.

Pursuant to Art. 32.2 of the By-laws and the aforementioned regulations, shareholdings in the share capital of the Company held by the Ministry of the Economy and Finance, public bodies, or organisations controlled by the latter are exempt from this provision.

Lastly, the special provision states that the clause regarding shareholding limits shall not apply if the above limit is exceeded following a takeover bid, provided that the bidder - as a result of the takeover - will own a shareholding of at least 75% of the capital with voting rights in deliberations regarding the appointment or dismissal of Directors31.

2.3 Securities that confer special rights

The Company has not issued securities that confer special controlling rights. The By-laws of Eni do not Provide for shares that give the holder a weighted vote.

2.4 Special powers of the State

Decree-Law No. 21 of March 15, 2012, ratified, with amendments, by Law No. 56 of May 11, 2012 ("Law No. 56/2012") brought Italian laws on the special powers of the State in line with European Union (EU) rules.

The special powers apply to companies in the defence and national security sectors, broadband electronic telecommunications networks with 5G technology as well as companies that hold strategic assets in the energy, transport and communications sectors as defined by implementing measures.

With reference to the energy sector, also following the changes made by Decree Law No. 21/2022 (so called the "Ucraina-Ter/Tagliaprezzi" in Italian) ratified by Law No. 51/2022, the special powers include: a) veto power or the power of imposing conditions or requirements over certain transactions, resolutions or deeds involving strategic assets (as identified by the Prime Ministerial Decrees No. 179 and 180 of 2020); b) power of attaching conditions or opposing the acquisition of an equity interest in companies that hold strategic assets such as to give rise to the assumption of control of the Company and the acquisition, by a non-EU party, of equity interests that allocate a share of voting rights or capital equal to 10 percent, taking account of the shares or stakes already directly or indirectly held, when the overall

³⁰ Art. 3 of Law No. 474/1994 was formally amended by Decree Law No. 21 of March 15, 2012, ratified, with amendments, by Law No. 56 of May 11, 2012. ³¹ Pursuant to Law No. 266 of 2005 (2006 Finance Act), to which a specific paragraph of this Report is dedicated, this clause would cease to apply if the rules regarding the issue of shares or participating financial instruments - such as those specified in the law itself - were included in the By-laws.

value of the investment is equal to or greater than €1 million, or they nevertheless exceed the thresholds of 15%, 20%, 25% and 50% of the share capital.

Companies that hold strategic assets or those who intend to acquire equity investments in such companies are required to notify the Prime Minister's Office with complete information on the resolution, deed or transaction on strategic assets or on the purchase of equity investments. The obligation of notification also extends to the establishment of an entity that carries out activities of strategic importance or holds strategic assets when one or more shareholders, outside the European Union, hold a share of voting rights or capital equal to at least 10 percent.

With specific regard to the power referred to in point b), until such notification and, subsequently, until the time period for any exercise of such power has begun, the voting rights or any rights other than property rights attaching to the material equity interest are suspended.

In the event of breach of the commitments imposed, for the entire relevant period the voting rights or any rights other than property rights attaching to the material equity interest are suspended. Any resolutions adopted with the decisive vote of such equity interest, or any other resolutions or acts adopted in violation or breach of the commitments imposed are void. In addition, except where the situation represents a criminal offence, non-compliance with the commitments imposed shall be punishable by a pecuniary administrative penalty.

In the event of objection, the acquiring party may not exercise the voting rights or any rights other than property rights attaching to the material equity interest, which such party shall sell within one year. In the event of failure to comply, at the request of the Government, the courts shall order the sale of the material equity interest. Resolutions of the shareholders' meeting adopted with the decisive vote of such equity interest are void.

These powers are exercised exclusively on the basis of objective and non-discriminatory criteria.

2.5 Shares and participating financial instruments referred to Law No. 266 of December 23, 2005

With the aim of "promoting privatisation and the diffusion of investment in shares" of companies in which the State holds a material shareholding, Art. 1, paragraphs 381-384 of Law No. 266 of 2005 (2006 Finance Act) allowed companies primarily controlled by the State, such as Eni, to insert provisions in their By-laws, whereby shares or participatory debt financial instruments can be issued that grant the special Shareholders' Meeting of the holders of these instruments the right to request that new shares — even at par value — or new participatory debt financial instruments with voting rights in the ordinary and extraordinary Shareholders' Meeting be issued to them.

Adopting this amendment would imply the elimination of the shareholding limit indicated in Art. 6.1 of the By-laws. At present, Eni's By-laws do not include this provision.

2.6 Material agreements that would become effective, be modified or extinguished in the event of a change of control of Eni32

Except as specified below, Eni and its subsidiaries are not parties to any material agreements that can be disclosed without causing serious prejudice to the Company, and that would become effective, be modified or extinguished should the Shareholders who control Eni change.

Material agreements are agreements that have been examined and approved by the Board of Directors since they fall within its exclusive responsibility.

It should be noted that on January 22, 2022 Eni SpA and CDP Equity SpA (previously CDP Industria SpA33) renewed the shareholders' agreement (signed for the first time on October 27, 2015) to exercise joint control over Saipem SpA, pursuant to which the same agreement shall immediately cease to be effective if the parties cease to be subject, directly or indirectly, to the common control of the Ministry of the Economy and Finance. The agreement has a duration of three years, with automatic renewal upon expiry for an additional three years, unless cancelled with at least six months' notice.

For more information, please see the documentation made available to the public in accordance with applicable law on the websites of Consob and Saipem SpA.

2.7 Agreements between the Company and Directors which envisage indemnities in the event of resignation or dismissal without just cause, or if their employment contract should terminate as the result of a takeover bid

Information on any agreements between the Company and Directors concerning indemnities in the event of resignation or dismissal without just cause or termination of employment as the result of a takeover bid are provided – in accordance with the Recommendations of Borsa Italiana for the preparation of this Report – in the Report on remuneration policy and remuneration paid pursuant to Art. 123-ter of the Consolidated Law on Financial Intermediation, published in the "Governance" section of the Company's website eni.com, in the chapter on "Officers covered by the Policy" to which the reader should refer for more information.

2.8 Powers to Directors to increase share capital, issue participatory debt financial instruments and authorisation to purchase treasury shares

³² In accordance with Borsa Italiana's recommendations on the preparation of this Report, the By-laws of the Company do not contain an exception to the passivity rule set out in Art. 104, paragraphs 1 and 1-bis, of the Consolidated Law on Financial Intermediation, nor do they require the application of the neutralisation rule provided for under Art. 104-bis, paragraphs 2 and 3 of such Consolidated Law.

³³On December 31, 2022, the merger by incorporation of CDP Industria SpA into CDP Equity SpA was completed and, taking effect on the same date, CDP Equity SpA took over from CDP Industria SpA in the shareholders' agreement and in all rights and obligations previously pertaining to the latter pursuant to that agreement.

The Board of Directors has not been given the power to increase the share capital pursuant to Art. 2443 of the Italian Civil Code. The Board of Directors does not have the power to issue participatory debt financial instruments.

As of March 17, 2022 Eni held 65,838,173 treasury shares, equal to approximately 1.83% of the share capital.

The Extraordinary Shareholders' Meeting held on May 11, 2022 approved the cancellation of 34,106,871 treasury shares with no nominal value, with no changes made to the amount of the share capital. Upon cancellation of the treasury shares, the Company held 31,731,302 treasury shares in the portfolio, equal to 0.89% of the share capital post-cancellation. Eni Shareholders' Meeting on the same day also authorised the Board of Directors to approve a programme for the purchase of Company shares, in multiple instalments for a period until April 30, 2023, in the maximum number of 10% of ordinary shares (and 10% of share capital) making up the share capital of Eni SpA (without including the treasury shares already in portfolio, equal to 0.89% of the share capital), in the maximum amount of € 2.5 billion.

Subsequently, the Board of Directors of Eni on May 26, 2022 resolved the start of the buyback programme for 2022, for a minimum amount of € 1.1 billion, potentially increasing to a maximum of € 2.5 billion, and for a number of shares not exceeding 357 million, in compliance with the provisions of the 2022-2025 Strategic Plan and in execution of the authorisation granted by the Shareholders' Meeting of May 11, 2022.

The Board of Directors of July 28, 2022 then resolved to increase the condition to purchase treasury shares for an amount of € 1.3 billion to € 2.4 billion following the review of the price scenario for the Brent benchmark, envisaged at \$ 105/barrel for the entire year of 2022, as well as the effects of the appreciation of the dollar and the Group's more robust cash flows.

On December 7, 2022, the conclusion of the Company's share buy-back programme for 2022 was announced to the market, launched on May 30, 2022 as announced to the market on May 26, 2022. As part of the programme, Eni purchased 195,550,084 treasury shares (equal to 5.48% of share capital) for a total value of € 2,399,992,593. Following the purchases made until November 29, 2022, considering the treasury shares already in the portfolio and the assignment of ordinary shares to Eni managers, following the conclusion of the vesting period provided for by the "2017-2019 Long-Term Incentive Plan" approved by Eni Shareholders' Meeting of April 13, 2017, Eni held 226,097,834 treasury shares equal to 6.33% of share capital. The share buy-back programme for 2022 was completed in 6 months from the start date, earlier than the indication of April 2023 communicated at the start of the programme.

Information on treasury shares is available in the "Shareholders" page of the "Governance" section of the Company's website.

3. Corporate governance information34

Eni adopted the 2020 Corporate Governance Code, in force since January 1, 2021

3.1 Compliance with the Corporate Governance Code

With resolution of the Board of December 23, 2020, Eni adopted35 the 2020 Corporate Governance Code36 (hereinafter the "Corporate Governance Code" or the "Code") whose recommendations are applicable starting from January 1, 2021, prepared by the Italian Corporate Governance Committee.

The adoption of the Corporate Governance Code is formally decided by the Board of Directors of Eni, with the support of the competent Committees where necessary. Following the adoption, on January 21, February 18 and April 1, 2021, the Board also approved some adaptation measures and application modalities, including improvements, to the new Code, while an "action plan" was defined to adapt the Company's governance system, including the identification of the changes to be made to corporate documents for the implementation of the new recommendations. Eni applies the recommendations of the Code intended for large companies, not with concentrated ownership, according to the definitions of the Code itself.

The adoption was announced to the public in a press release.

In addition, in order to provide the market with a simple, transparent and comparable assessment of the choices made by the Company, and maintain the continuity of disclosures, the text of the Corporate Governance Code, integrated with the application modalities, including improvements, adopted by Eni in relation to individual recommendations, accompanied by the related reasons, is published before publication of the annual Corporate Governance Report on Eni's website eni.com (under the Governance section)37.

Therefore, starting from January 1, 2021, roles, responsibilities and regulatory instruments of the Company must take into account the new recommendations provided for by the Corporate Governance Code, as well as the decisions taken by the Board of Directors regarding the application modalities of the same recommendations.

The following sections details the decisions taken by the Eni Board of Directors in adopting the recommendations of the Corporate Governance Code.

ROLE OF THE BOARD OF DIRECTORS (ART. 1 OF THE CORPORATE GOVERNANCE CODE)

In line with the recommendations of the Corporate Governance Code the functions of the Board of Directors have been defined, thereby confirming its strategic role and central position within the Company's Corporate Governance system and its wide range of responsibilities, including in terms of Company and Group organisation and the Internal Control and Risk Management System38.

³⁴ Corporate Governance information is provided in accordance with the provisions of Art. 123-bis, first paragraph, letters e) and l), and second paragraph, of the Consolidated Law on Financial Intermediation.

³⁵ The Board adopted the Corporate Governance Code for the first time (ed. 1999) with a resolution of January 20, 2000 and, subsequently, with resolutions of December 13, 2006, December 15, 2011, April 26, 2012, December 11, 2014, February 25, 2016 and February 14, 2019.

³⁶ The text of the Corporate Governance Code is available to the public on the website of Borsa Italiana and the Italian Corporate Governance Committee at https://www.borsaitaliana.it/comitato-corporate-governance/codice/2020eng.en.pdf.

³⁷ The document, which replaced the Eni Code of December 13, 2006, was updated the subsequent adoptions to the Corporate Governance Code of 2011, 2014, 2015, 2018 and 2019.

³⁸ For more information, please refer to the section "Internal Control and Risk Management System" of this Report.

In addition, since 2006, the interests of stakeholders other than shareholders have been considered key variable that the Directors of Eni must assess in taking informed decisions and in creating value over the medium-to-long-term. In addition, in September 2019, Eni adopted a mission that integrates the 17 Sustainable Development Goals of the United Nations, which embrace every area of social, economic and environmental development, viewed in an integrated and organic way, to which Eni intends to provide an active contribution. The choices of the Board of Directors implement, also improving it, Principle I of the Code, which recommends that "the Board of Directors leads the Company by pursuing its sustainable success"39.

In particular, a central role is reserved for the Board of Directors, upon the proposal of the CEO, in the definition of the strategic guidelines and objectives of the Company and the Group, pursuing the sustainable success and monitoring their implementation.

In particular, it reviews and approves the Four-Year Plan and the medium/long-term plans of Eni and the Group and the respective budgets, also on the basis of the matters that are relevant for the long-term value generation, and the support of the Sustainability and Scenarios Committee (Recommendation 1, letter a) of the Code), periodically monitors its implementation and assesses the general course of the business, comparing the results achieved with those planned (Recommendation 1, letter b) of the Code). Furthermore, the Board defines, with reference to the Four-Year Plan, the nature and level of risk compatible with the strategic objectives of the Company, on the basis of a risk probability and impact estimate prepared (and, if necessary, updated during the year) by the Integrated Risk Management function, including within its assessments all elements that could be relevant for the Company's sustainable success (Recommendation 1, letter c) of the Code).

The Board has engaged in establishing the general criteria for identifying significant transactions for the Company and its subsidiaries that have a significant impact on the company's strategies, profitability, assets and liabilities, or financial position, submitted for approval by the Board itself (Recommendation 1, letter e) of the Code), adopting conduct and procedural controls regarding those cases in which the Directors and Statutory Auditors have an interest of their own or on behalf of another, including in the case of transactions with related parties of Eni. The Board also takes care to ensure compliance with the principle of correct corporate and entrepreneurial management of subsidiaries, and that their managerial independence is not compromised, in particular in the cases of listed companies and companies for which legislative or regulatory provisions make it necessary. This is without prejudice to the compliance with confidentiality obligations relating to commercial relations between the subsidiary and Eni or third parties, for the protection of the interest of the subsidiary.

The Board has also specified the subsidiaries40 that are of strategic importance (Versalis SpA, Eni Plenitude S.p.A. Società Benefit and Eni International BV) also for the purposes of applying the relevant Recommendations of the Code and, in addition to the aforementioned principle of safeguarding, the managerial independence of listed subsidiaries, has undertaken to observe the provisions of the Code referring to the shareholders of the issuer. Subsidiaries with strategic importance

The Board also has the task of defining the corporate governance system and rules of the Company, assessing and promoting the suitable changes, where necessary, and submitting them, where applicable, to the Shareholders' Meeting, as well as defining the structure of the Group. It defines the fundamental lines of the organisational, administrative and accounting

³⁹ The Code defines "sustainable success" as the objective that guides the action of the Board of Directors and that consists of creating long-term value for the benefit of shareholders, taking into account the interests of other stakeholders relevant to the Company.

⁴⁰ With reference to Saipem SpA, which since January 22, 2016 is no longer under the sole control of Eni in accordance with Art. 93 of the Consolidated Law on Financial Intermediation, the Board of Directors confirmed its competence to resolve on the exercise of voting rights and, after hearing the Nomination Committee, on the appointment of the members the corporate bodies of Saipem SpA.

structure, including the Internal Control and Risk Management System, of the Company, the subsidiaries with strategic importance and the Group, and to assess their adequacy, with particular reference to the internal control and risk management system (Recommendation 1, letter d). In particular, every six months, it has provided for the assessment of the adequacy and effectiveness of the Internal Control and Risk Management System and annually also the assessment of the adequacy and effectiveness of the organizational structure of this system, unless changes require a six-monthly update.

With respect to the correct management of corporate information (Recommendation 1, letter f), in October 2018 the Board, acting on a proposal of the CEO and after consultation with the Control and Risk Committee, approved the internal rules concerning Market Information Abuse (Issuers) which, updating the previous internal rules for aspects related to "issuers", complies with the modification introduced by Regulation No. 596/2014/EU of April 16, 2014 and by related implementing regulations, as well as with national regulations, taking into account the Italian and foreign institutional guidelines on the subject41.

On the occasion of the adoption and implementation of the Recommendations of the Code, with reference to Principle III and Recommendation 2, the Board did not deem it necessary to submit proposals for amendments to the Company's corporate governance system to the Shareholders' Meeting, including in light of the assessments made by the previous Board. An additional check was carried out in 2022 by the Board of Directors in office, following which it was not considered necessary to make changes to the current system.

Finally, the Board, upon the proposal of the Chairman, in agreement with the Chief Executive Officer, in the meeting of March 8, 2022 approved a policy for managing dialogue with the generality of shareholders42, also taking into account the engagement policies adopted by institutional investors and asset managers (Recommendation 3 of the Code). For more information, please refer to the dedicated paragraph of this report. The dialogue with other relevant stakeholders, promoted by the Board starting from the definition of the principles and guidelines set out in the Company's Code of Ethics, is governed by other Eni regulatory instruments43.

COMPOSITION OF THE CORPORATE BODIES (ART. 2 OF THE CORPORATE GOVERNANCE CODE)

In line with the By-Laws and the Corporate Governance Code (Recommendation 4), the Board of Directors has appointed a CEO, to whom it has entrusted the management of the Company, reserving the decision on certain matters to its sole competence. The CEO is therefore the person responsible in charge of managing the Company.

For the composition of the Board, the Shareholders' Meeting could take into account the guidelines given to the market by the previous body as regards diversity, professionalism, experience, and skills, also with regard to the strategies of the Company, its transformation and the path of energy transition. The size and composition, also in terms of diversity, of the Board are subject to evaluation within the annual Board Review.

The number of independent Directors pursuant to the Code (7 out of 9) is already higher than that recommended by the Code for large companies with non-concentrated ownership, starting from the first renewal after December 31, 2020, at least half of the body (Recommendation 5).

⁴¹ For more information, please refer to the "Management System Guideline Market Information Abuse (Issuers)" section of this Report.

⁴² The complete policy for managing dialogue with the shareholders is published, also in English, in the "Governance" section of Eni website.

⁴³ For more information, please refer to the "Responsible and sustainable approach and dialogue with stakeholders" section of this Report.

Eni specifications for independence criteria Since 2006, when the previous versions of the Corporate Governance Code were in force, Eni's Board of Directors has provided specifications for the independence criteria of Directors.

Following the adoption of the Corporate Governance Code, before the annual assessment and taking into account the new Recommendations, the Board, with the support of the Nomination Committee, defined again the criteria for assessing the significance of the additional remuneration and relationships that may jeopardise the independence of a director, confirming certain past choices. It also adopted the criteria established by the Corporate Governance Code for the definition of close relatives, as listed in the related Q&A44.

The periodic assessments on the continued compliance with independence requirements by the Directors are carried out by the Board of Directors with the support of the Nomination Committee, which carries out a preliminary investigation on the basis of the declarations issued by the Directors and the information available to the Company.

During the year, independent Directors, coordinated by the lead independent director appointed in April 2021, met on March 16, 2022 and on July 28, 2022 and, taking into account the frequency of the Board meetings, they had further informal opportunities to meet and exchange views, thoughts and comparisons, in compliance with the Recommendations of the Corporate Governance Code.

Since December 13, 2006, the Board of Statutory Auditors expressly complies with relevant governance provisions; with particular reference to independence, since January 2016 the Board of Statutory Auditors confirmed the criteria adopted by the Board to evaluate independence, with some specifications45.

In terms of diversity, including gender diversity, the Board of Directors identified the guidelines to the shareholders by the outgoing Board as one of the tools to implement related recommendations of the Corporate Governance Code46.

Moreover, on February 27, 2020, the Board approved an amendment to the By-laws regarding gender quotas in the composition of corporate bodies to adapt them to regulatory changes introduced with Law No. 160 of 2019 in view of the renewal of the corporate bodies, providing that, for six consecutive terms, the management and control bodies must be composed of at least 2/5 of the less represented gender.

The Code recommends that companies apply the quota of one third for the less represented gender in the administration and control bodies (Recommendation 8) starting from the first term following the cessation of the effects of legislative provisions that impose a quota equal to or greater than that recommended by the Code47.

FUNCTIONING OF THE BOARD OF DIRECTORS AND THE ROLE OF THE CHAIR (ART. 3 OF THE CORPORATE GOVERNANCE CODE)

In line with Principle IX and with Recommendation 11 of the Corporate Governance Code, the Board defined in its Rules, approved most recently on December 16, 2021, the Rules and procedures for its operation, in particular in order to ensure the effective management of Board information48. It also approved, most recently in December 2021, the Rules of the individual Board Committees49.

⁴⁴ For more information, please refer to the "Independence requirements" section of this Report.

⁴⁵ For more information, please refer to the Board of Statutory Auditors section in this Report.

⁴⁶ For more information, please refer to the "Board Review and guidelines for shareholders on the composition of the Board" section in this Report.

⁴⁷ For more information, please refer to the "Policy for diversity and gender balance on corporate Boards" section in this Report.

⁴⁸ For more information, please refer to the section "Meetings and running of meetings" of the Board of Directors in this Report. 49 For more information, please refer to the sections dedicated to the Board Committees in this Report.

The Chairman, who plays a liaison role between executive and non-executive directors and is responsible for the effective functioning of the Board (Principle X of the Code), ensures, with the assistance of the Board Secretary, that pre-meeting information and complementary information provided during the meetings are suitable to allow the Directors to act in an informed manner50 (Recommendation 12, letter a) of the Code); the Chairman also ensure the coordination of Committees activities with those of the Board (Recommendation 12, letter b) of the Code). The Chairman has also the task of ensuring, in agreement with the CEO and with the assistance of the Board Secretary, that the managers of the Company and those of the companies of the Group, who are competent on the issues concerned, participate in the relevant Board meetings, to provide appropriate insights on the items on the agenda, also at the request of individual directors (Recommendation 12, letter c) of the Code).

To ensure an effective and aware performance of their role by each Director, the Chairman ensures, with the assistance of the Board Secretary, that all the members of the Board of Directors and of the Board of Statutory Auditors can take part, after the appointment and during their term, in initiatives aimed at providing them with adequate knowledge of the industry in which the company operates, the company dynamics and their evolution, also in relation to the company's sustainable success, as well as the principles of correct risk management and the regulatory and self-regulatory framework (Recommendation 12, letter d) of the Code). To this end, a training plan for Eni's Board of Directors has been prepared and implemented since 2008 (the so-called "Board induction"51) – which the Statutory Auditors and the Magistrate of the Court of Auditors are also invited to attend – by the Chairman of the Board of Directors with the help of the Board Secretary and the active participation of the top management. Furthermore, according to international best practices, further efforts are carried out during the term (so-called "ongoing-training") and it is expected that at least once a year, where possible, the Board will meet at one of Eni's operating sites, also abroad. The Chairman also ensures, always with the assistance of the Secretary, the adequacy and transparency of the self-assessment process of the Board of Directors, with the support of the Nomination Committee (Recommendation 12, letter e) of the Code)52.

As regards the offices within the Board, in line with the By-Laws and applicable best practices, the Eni model establishes a clear separation between the functions of Chairman and those of the Chief Executive Officer, conferring management powers only on the latter. The Board of Directors, on the other hand, has conferred on the independent Chairman a central role in the internal control system, not granting her operational powers and ensuring her the support, in the performance of her duties, of the Board Secretary, appointed by the Board.

Pursuant to Art. 24.1 of the By-Laws, the Board of Directors has given the Chairman the powers for the identification and promotion of strategic integrated projects and international agreements, with the collaboration of the CEO. This is a proxy without executive or decisionmaking content, as it concerns only "identification" and "promotion" activities, which can only lead to proposals to those with decision-making powers (the Chief Executive Officer or the Board of Directors).

On April 29, 2021, the Board of Directors, upon the request of the independent directors, appointed Director Vermeir as lead independent director (Recommendation 13, letter c) of the Code). The lead independent director represents a point of reference and coordination of requests and contributions of non-executive directors and, in particular, independent ones, and coordinates the meetings of the independent directors only.

With reference to the advice on the maximum number of offices in corporate bodies of other listed companies that can be considered compatible with an effective performance of the

office of director, the Board has adopted different criteria based on the role (executive or nonexecutive) and in relation to the nature and size of the company in which the offices are held (Recommendation 15 of the Code) 53.

The Eni Board has always had all of the committees provided for under the Corporate Governance Code54; it also established, exceeding the Code provisions, that the number of members of such committees (Control and Risk Committee, Nomination Committee and Remuneration Committee) shall not represent a majority of the Board, so as to avoid altering the Board's decision-making process (Recommendation 16 of the Code).

Furthermore, the Eni Board of Directors has established the Sustainability and Scenarios Committee55, to offer recommendations and advice concerning sustainability issues, thereby anticipating the amendments made to the Corporate Governance Code in July 2015 (comments to Article 4 of the 2018 Corporate Governance Code).

With specific regard to the composition of the Committees, the Chairs of all Committees are independent Directors in accordance with the provisions of law and Corporate Governance Code; the Chairs of the Control and Risk Committee and the Sustainability and Scenarios Committee are also appointed from the minority slate. Moreover, the Remuneration Committee and the Control and Risk Committee also have more members meeting the knowledge and experience requirements than the minimum provided for in the Code (Recommendations 26 and 35 of the Code).

With regard to reporting, since 2012, at each Board meeting the Chairmen of the Committees report to the Board itself on the most significant issues examined by them at their most recent meetings. The Eni Board also receives reports at least every six months on the Committees' activities (Recommendation 17 of the Corporate Governance Code). Reporting

On the proposal of the Chairman, the Board appointed a Board Secretary, in possession of specific professional requirements, determining the relative powers. The Secretary supports the activities of the Chairman and provides impartial assistance and advice to the Board of Directors on every aspect relevant to the proper functioning of the corporate governance system as concerns the functioning, powers and attributions of the Board and the Committees (Recommendation 18 of the Code)56.

APPOINTMENT OF DIRECTORS AND BOARD EVALUATION (ART. 4 OF THE CORPORATE GOVERNANCE CODE)

Particular attention is always devoted to the Board's self-evaluation process, concerning the size, composition and functioning of the Board and its Committees, also in consideration of the role it plays in defining the strategies and monitoring the management of the company's business, as well as the appropriateness of the Internal Control and Risk Management System (Recommendation 21 of the Code). In particular, in line with the Recommendations of the Corporate Governance Code (Principle XIV), the Board of Directors annually carries out a "Board Review" program57 on the Board and its Committees and, improving corporate governance provisions, always involves an external consultant in this exercise, in order to ensure greater objectivity to the proceedings (Recommendation 22 of the Code). Board Review

⁵⁷ For more information, please refer to the "Board Review and guidelines for shareholders on the composition of the Board" section in this Report.

The comparison with best practices and a reflection on Board dynamics are essential elements of Eni's Board Review. In addition, the review also considers diversity criteria in the composition of the Board, as recommended by the Code.

Following the Board Review, the Board may, if necessary, share an action plan to improve the operation of the Board and its committees.

In line with international best practices, in determining the procedures for performing the Board Review, the Eni Board also assesses whether to carry out a process of "peer review" of the Directors, consisting in the evaluation by each Director of the individual contribution of the other Directors to the Board's work. The peer review, which has been completed five times in the past nine years and was most recently completed in conjunction with the 2020 Board Review, is a best practice among Italian listed companies; Eni was among the first Italian companies to adopt it in 2012.

Prior to the appointment of the new Board, as already happened in 2014, 2017 and 2020, following the Board Review completed in February 2023 the outgoing Board, with the help of the Nomination Committee, expressed its guidelines for shareholders on the quantitative and qualitative composition of the future Board, also in light of the industrial characteristics of the Company, taking into account the diversity criteria indicated by Principle VII and Recommendation 8 of the Code58.

To regulate the aforementioned activities in detail, Eni has adopted an internal procedure59, approved by the Chairman in agreement with the CEO, as part of the functions of the Secretary of the Board of Directors, with particular reference to assignment activities, the functions and bodies involved, as well as the definition of the tools to support the process.

The Board of Directors established a Nomination Committee, endowing it with the advisory functions in the areas provided for in the Corporate Governance Code and for other issues concerning, in particular, the appointment system and the assessment of requirements for Directors60.

With reference to the Recommendations relating to the succession plan of the CEO (Recommendation 24 of the Code), the Board of Directors has adopted a "contingency plan" which identifies the procedures to be followed in the event of early termination of the office of the Chief Executive Officer61. The Board also ascertained the existence of adequate procedures for the succession of top management. The contingency plan

REMUNERATION OF DIRECTORS (ART. 5 OF THE CORPORATE GOVERNANCE CODE)

The Remuneration Committee, which assists the Board in drawing up the Remuneration Policy and carries out the other tasks provided for by the Code (Recommendation 25 of the Code), has a number of members meeting the requirements of knowledge and experience in excess of the minimum required by the Code: in fact, on May 14, 2020, the Board of Directors of Eni assessed, upon the appointment, that all the members of the Committee possess adequate knowledge and experience in financial matters or remuneration policies.

In accordance with the suggestions of Borsa Italiana on preparing this Report, details on compliance with the recommendations concerning remuneration are contained in the Report

⁵⁸ For more information, please refer to the "Board Review and guidelines for shareholders on the composition of the Board" section in this Report.

⁵⁹ The letter of the Chairman of the Italian Corporate Governance Committee in 2017 listed the main areas needing improvement, underling the importance of introducing structured procedures for the Board Review activities. In this regard, it should be noted that Principle XIV of the new Code provides that "the Board of Directors periodically evaluates, through formalised procedures, its effectiveness and the contribution made by individual directors. The implementation of the Board evaluation procedures is supervised by the Board itself."

on remuneration policy and remuneration paid, prepared pursuant to Art. 123-ter of the Consolidated Law on Financial Intermediation, to which the reader is referred.

INTERNAL CONTROL AND RISK MANAGEMENT SYSTEM (ART. 6 OF THE CORPORATE GOVERNANCE CODE)62

Eni's Internal Control and Risk Management System (ICRMS) is integrated into the organisational, administrative and accounting structure of the Company and, more generally, the structure of corporate governance and complies with the recommendations of the Corporate Governance Code and, in general, with national and international benchmark models and best practices in the field.

For further information and details on the application modalities, including improvements, of the Code, please refer to the section of this Report dedicated to the ICRMS.

OBSERVATIONS ON THE LETTER OF JANUARY 2023 OF THE CHAIRMAN OF THE ITALIAN CORPORATE GOVERNANCE COMMITTEE

At its meeting of February 22, 2023 the Chairman of the Eni Board of Directors notified the Board of a letter sent in her capacity as Chair of the Italian Corporate Governance Committee (since May 2021) to the Chairs of the Boards of Directors and of the control bodies and the Chief Executive Officers of listed companies indicating the main areas for improvement and related recommendations identified by the Committee to support the companies in the effective application of the 2020 Corporate Governance Code, also in light of the findings of the 2022 Report of the Committee, sent together with the letter.

The documents were also made available to the Statutory Auditors in the same meeting.

The areas of improvement indicated by the Italian Corporate Governance Committee and the position of Eni

With regard to the areas of improvement indicated in the letter (concerning the following matters: (i) dialogue with shareholders and other relevant stakeholders; (ii) allocation of managerial powers to the chairman; (iii) pre-meeting information; (iv) participation of managers in Board meetings; (v) guidelines on the optimal composition of the Board; (vi) criteria for assessing the significance of the relationship that could influence the director's independence; (vii) transparency of remuneration policies on the weighting of variable components; (viii) long-term outlooks in the remuneration policies; (ix) ESG parameters for the remuneration of directors), the above-mentioned Board documentation underlined that Eni was broadly in line with the Committee's recommendations.

The Chairman of the Board of Directors also invited the Chairmen of Eni Board Committees to take into account the recommendations in the activities under their remit and to submit any further reflections or initiatives to the Board.

The advisor was asked to consider the recommendations in the letter in the Board Review.

3.2 Policy for diversity and gender balance on corporate bodies63

In line with the provisions of law and the Recommendations of the Corporate Governance Code, the Company has implemented measures to ensure diversity in the composition of Eni SpA and its subsidiaries, with particular regard to age, gender composition and educational and professional background.

⁶² For detailed information on the methods for implementing the criteria and the principles of the Corporate Governance Code as well as its Principles and recommendations relating to the Internal Control and Risk Management System, refer to the relevant section of this Report.

⁶³ Information provided also in accordance with Art. 123-bis, second paragraph, letter d-bis) of the Consolidated Law on Financial Intermediation.

ENI SPA64

Gender diversity in the corporate bodies of Eni SpA

With regard to gender balance, in compliance with applicable law since 2012 the Eni By-laws have contained rules governing the composition of the slates and supplemental voting mechanisms to ensure the presence on the Board of Directors and the Board of Statutory Auditors of a minimum number of members of the less represented gender. These rules, which were referred to in the outgoing Board's guidelines to shareholders, took effect as from the election of the corporate bodies of Eni SpA in 2014, on which occasion the composition of the Board of Directors and of the Board of Statutory Auditors achieved gender balance, as required by law in force at the time65 immediately giving the less represented gender one-third of the seats in the Board of Directors, compared with the one-fifth provided for by law. Furthermore, as already mentioned, on February 27, 2020 the Board approved an amendment to the By-laws to adapt them to Law No. 160/2019 providing that, for six consecutive terms, the administrative and control bodies must be composed of at least 2/5 of the less represented gender.

The Shareholders' Meeting of Eni SpA, in appointing the new Board in 2020, ensured a balanced gender representation electing four female Directors out of nine, equal to more than two-fifths of the Directors: Chairman Lucia Calvosa and Directors Ada Lucia De Cesaris and Nathalie Tocci, drawn from the majority slate, and Director Karina Litvack, from the minority slate. The Shareholders' Meeting also chose two female Standing Statutory Auditors out of five (Rosalba Casiraghi, Chairman, from the minority slate, and Giovanna Ceribelli, from the majority slate). In addition, following the resignation of a Standing Statutory Auditor in September 2020, the Shareholders' Meeting of May 12, 2021 restored the composition of the Board of Statutory Auditors by appointing an additional female Standing Statutory Auditor (Marcella Caradonna). Therefore, three of five members of the Board of Statutory Auditors belong to the female gender.

As regards other aspects of diversity in its composition, the Board of Directors, upon the implementation of the Recommendations of the Corporate Governance Code, has identified in the guidelines for shareholders of the outgoing Board one of the tools to implement the Recommendations on diversity (Recommendation 8 of the Code), and, in any case, the tool to implement other Principles and Recommendations of the Code regarding the composition and requirements applying to the corporate bodies, without prejudice to the responsibility of the shareholder and the provisions of the law and By-Laws (in particular, Principles V, VI, VII and Recommendation 5).

⁶⁴ More generally, note that "diversity policy" in the selection of candidates and the composition of the Eni SpA corporate bodies is first and foremost in the hands of the shareholders of Eni SpA, who submit slates for the election within the framework of the Italian system for electing corporate bodies. No slate has ever been presented by the outgoing Board, even if this is allowed under the By-laws.

⁶⁵ Law No. 120/2011 and Consob Resolution No. 18098 of 2012. In particular, the law stated that in the first term, a quota of least one fifth of the Directors and Standing Statutory Auditors elected and at least one third in the following two terms be reserved for the gender less represented.

Similarly, with reference to Principle VIII, providing that "the control body's composition is appropriate for ensuring the independence and professionalism of its function", upon the implementation it was specified that, without prejudice to the provisions of the law and the By-Laws, the Recommendation applies more significantly to the shareholder and can be taken into consideration by the control body in the guidelines for shareholders on the composition of the body itself.

With reference to the Board of Directors, the guidelines were formulated in view of the Shareholders' Meetings called for the appointment of the Directors in 2014, 2017, 2020, and, most recently, in 202366. Guidelines of the Board of Directors

In particular, on the occasion of the guidelines for shareholders approved by the outgoing Board of Directors, having received the opinion of the Nomination Committee, on February 27, 2020, the diversity issues listed in Art. 123-bis, paragraph 2, letter d-bis) of the Consolidated Law on Financial Intermediation and in the then 2018 Corporate Governance Code were taken into consideration, as were the outcomes of Board Review, which examined it, also adding further aspects of diversity with respect to those recommended by the Code and the Law (e.g. in terms of specific skills).

Moreover, on the basis of the results of the Board Review, the Board underlined that its composition had to take into account, among other things, the need for diversity, including gender, and professional background, experience and skills, also considering the strategies of the Company, its transformation and the path of energy transition.

Therefore, the current membership of the Board appears to be in line with these recommendations.

Including in view of the Shareholders' Meeting called for the appointment of the Directors in 2023, during the meeting of February 22, 2023, the Board Directors, with the assistance of the Nomination Committee, approved the guidelines for shareholders on the quantitative and qualitative composition considered to be optimal. For more information, please refer to the "Board Review and guidelines for shareholders on the composition of the Board" section in this Report.

Moreover, the aspects relating to diversity in the composition of the Board in office were the subject of specific in-depth analysis of the Board Review process, as described in the aforementioned section, to which the reader should refer.

The diversity issues regarding the composition of Eni's Board of Statutory Auditors, other than the question of gender balance referred to earlier, also underwent analysis in the review conducted by the Board of Statutory Auditors, following which the Board issued, in light of the 2020 and 2023 renewals, its guidelines for shareholders on the future composition. Guidelines of the Board of Statutory Auditors

ENI'S SUBSIDIARIES

Since 2011, the Board of Directors of Eni has recommended that the unlisted Italian subsidiaries move forward the effects of the law on gender balance in the composition of corporate bodies, thereby achieving in 2012 the goal that at least one third of the members on Boards of Directors and Boards of Statutory Auditors appointed are women with regard to those appointments that Eni may make as a shareholder.

In 2013, these companies amended their By-Laws to ensure, for three consecutive terms, the compliance with the aforementioned compositions67 (of the Boards of Directors and the Boards of Statutory Auditors) including in the case of replacement of a member. More

⁶⁷ Specified in Art. 2 of Presidential Decree No. 251 of November 30, 2012.

specifically, they must ensure that the less represented gender receives at least one-fifth of the positions of each Board in the first election and one-third of the positions in the next two elections in compliance with applicable legislation (Law No. 120/2011 and Presidential Decree No. 251/2012).

Art. 6 of the Law No. 162/2021, which entered into force on December 3, 2021, extended the rules on gender equality in the composition of the Boards of Directors of companies listed on regulated markets pursuant to art. 147-ter of the Consolidated Law on Financial Intermediation to State-controlled companies incorporated in Italy, pursuant to art. 2359 of the Italian Civil Code not listed on regulated markets. On the basis of these provisions, for six consecutive terms, the less represented gender must obtain at least 2/5 of appointed Directors68. The law puts off changes to be made to Presidential Decree No. 251/2012 to a subsequent regulation69; Eni applies the new provisions to Italian subsidiaries that, in the meantime, are called to renew their management bodies after the expiry of the obligation under Presidential Decree No. 251/2012.

The following chart illustrates the representation of women on the corporate bodies of Eni subsidiaries at December 31, 2022.

The Management System Guideline "Corporate Governance for Eni companies"70 provides that, subject to legal requirements, in choosing the members of the management and control bodies of its foreign subsidiaries, Eni must also promote diversification where possible. In particular, with reference to gender diversity, in the absence of specific legal obligations: a) in the subsidiaries established in Italy, at least two fifths of the members of each corporate body must belong to the less represented gender; b) in the subsidiaries established abroad, where possible, at least one fifth of the members of each corporate body must belong to the less represented gender. In case of subsidiaries with a presence of minority third-party shareholders, unless agreed otherwise, compliance with the quota of the less represented gender is ensured by Eni as the parent company.

⁶⁸ The rules on Boards of Statutory Auditors remain unchanged for the purposes of the composition and duration of the regulatory obligation. In these respect Presidential Decree No. 251/2012 still applies.

⁶⁹ At the date of approval of this Report, the regulations have not yet been adopted. 70 For more information, refer to the section "Management System Guideline Corporate Governance for Eni companies" of this Report.

3.2.1 DIVERSITY AND INCLUSION71

Eni's approach to Diversity & Inclusion (D&I) is based on the fundamental principles of nondiscrimination, equal opportunities and inclusion of all forms of diversity, as well as the integration and balance of work with the personal and family needs of Eni's people.

Eni's focus on an inclusive culture is stated in the corporate mission, in the regulatory framework and in many company documents (Code of Ethics, "Our People" Policy, Declaration on Respect for Human Rights, Framework Agreement on Industrial Relations, Report on Remuneration).

The company management ensures the carrying out of activities and achievement of objectives with an inclusive approach and operating methods aimed at creating a working environment in which different characteristics or personal and cultural beliefs are considered a resource and a source of mutual enrichment and an essential element of business sustainability.

Overall coordination is also ensured by the Diversity & Inclusion unit, reporting to the Director Human Capital & Procurement Coordination, who in turn reports directly to the Chief Executive Officer, with the aim of developing the corporate strategy on D&I and coordinating the portfolio of initiatives, also in collaboration with Eni's Human Resources and Sustainability functions.

Eni's D&I strategy sets out several main objectives:

to promote innovation and competitive edge by combining business objectives and appreciating uniqueness;
to promote the well-being and therefore the performance of all Eni personnel as individuals and as part of the corporate system;
to create a sustainable inclusion process.

The varied application of the D&I strategy envisages:

a focus on two strategic lines of action, namely an inclusive mindset and actions targeting priority clusters for Eni such as gender, international figures, age, disability and sexual orientation;
definition, implementation and periodic monitoring with other corporate functions involved, of a plan of actions identified annually also as a follow-on to listening and communication initiatives;
the involvement and engagement at all levels of the organisation to promote widespread individual accountability;
the construction of a culture of listening that includes various perspectives and leads to a growth in awareness;
stronger internal and external communication to create and showcase a culture of inclusion focused on appreciation for people's uniqueness.

As part of their direct responsibilities, the corporate functions ensures the implementation of inclusion initiatives with the support of a performance management system aimed at achieving improvements in the areas of human capital development, both in relation to specific indicators and with regard to personal behaviour.

In 2022, the following training and communication initiatives continued aimed at raising awareness and overcoming obstacles to diversity recognition and the risks of non-inclusion: (i) D&I Matters, a path focused on some typical areas of diversity, analysed through the lens of unconscious bias and actions aimed at overcoming the stereotypes; (ii) Eni for Inclusion, a

⁷¹ Information provided also in accordance with Recommendation 8 of the Corporate Governance Code, which provides that "Companies adopt measures to promote equal treatment and opportunities among genders within the entire organisation, monitoring their specific implementation".

month dedicated to spreading a diversity-enhancing culture; (iii) Creating a D&I Community, which has consolidated its position as a direct communication tool for D&I activities with high levels of engagement and interaction; (iv) launch of the direct listening project for personnel abroad (with 17 countries involved so far) to respond to D&I needs, new ideas and areas of improvement in the international context in which Eni operates72.

Gender equality

In line with the long-term objective to increase the presence of women by 3 percentage points (baseline 2020) by 2030, we have identified a set of qualitative-quantitative actions and metrics representing the main monitoring tool of the presence and empowerment of women in the company:

attraction of female talent, through the organisation and promotion of initiatives to encourage students towards STEM subjects (Science, Technology, Engineering and Mathematics), with a focus on gender equality (InspirinGirls, Think About Tomorrow, Coding Girls) and the growing and effective testimony of role models and internal ambassadors specifically trained to represent equal opportunities for women employed in the energy sector;
inclusion of women and female replacement rate, through constant verification and progressive improvement of the target for balancing female entries with a commitment to keep the turnover of female personnel higher than that of male personnel;
enhancement of female presence, with particular focus on the main career milestones, the appointment in leadership positions and on the Boards of directors of Eni subsidiaries. In this context, specific projects were also launched in order to support women's development with the aim of consolidating good practices for managing internal equality;
comparison with peers, both nationally and internationally, by joining associations and participating in inter-company surveys and benchmarks for sharing best practices and checking that the company requirements match the subject areas indicated by the reference standards. In this area, Eni has participated in selfassessments of the main national standards (Italian Practice for Gender Equality) and international ratings. This led Eni to be included in the Bloomberg Gender Equality Index and in the Equileap Top 100.

The first cycle of assessments envisaged as part of adopting the Women's Empowerment Principles (signed by the Eni CEO in December 2021) was also carried out, during which Eni was classified as an Achiever with a score of 51% (at global level, only 20% of companies that underwent the self-assessment exceeded the threshold of 50%);

continuous training of management and personnel in order to consolidate an internal culture of respect for and inclusion of women following the adoption of a company rule against discrimination and harassment, which incorporates the indications of the ILO190 Convention;
creation and adoption of communication campaigns intended to support women, such as #IoConLei - Orange the World by the United Nations to end violence against women;
partnerships intended to strengthen female empowerment and entrepreneurship (e.g. Women X Impact).

In 2022, the percentage of female employees in the company increased again compared to 2021, to 26.86%. In terms of turnover, a higher replacement rate for women than for men was also guaranteed in 2022 (respectively 1 vs. 0.73). For more information, please refer to the Consolidated Disclosure of Non-Financial Information in the Annual Report.

3.3.2 METHODS OF CALLING AND PARTICIPATING IN THE SHAREHOLDERS' MEETING

CALLING THE SHAREHOLDERS' MEETING

Minimum threshold for calling the Shareholders' Meeting

The Shareholders' Meeting is usually called by the Board of Directors76. In addition, in order to ensure greater clarity for shareholders, the By-laws clarify the minimum threshold equivalent to one-twentieth of share capital - required for calling the Shareholders' Meeting at the request of the shareholders, while also outlining the restrictions and methods specified by law for exercising said option77.

In line with the applicable law, the By-laws state that the Board of Directors may call the Shareholders' Meeting to approve the annual financial statements within 180 days from the

close of the financial year, subject to the publishing of the draft financial statements approved by the Board of Directors within four months from the close of the financial year.

Both the ordinary and extraordinary Shareholders' Meetings, pursuant to Art. 16.2 of the Bylaws, are normally held after a single call. The Board of Directors may decide to hold both kinds of Shareholders' Meetings after more than one call, if appropriate. In any case, the constitutive and deliberative majority specified by the law shall apply.

NOTICE CALLING THE SHAREHOLDERS' MEETING

The Shareholders' Meeting is called by a notice published no later than thirty days prior to the date of the Shareholders' Meeting at first or single call78, on the Company's website and in the other manners set forth by Consob in a regulation, including publication of an extract in daily, newspapers, and circulation through the centralised storage mechanism authorised by Consob called (viewable at ). Notice publication

This deadline, in accordance with Art. 125-bis, second paragraph, of the Consolidated Law on Financial Intermediation, is moved to forty days for Shareholders' Meetings called to elect members of the management and control bodies through the use of slates.

The notice calling the meeting, the content of which is defined by the law and the By-laws, contains all the necessary instructions on how to participate in the Shareholders' Meeting including, in particular, information on how to obtain proxy forms and vote by mail forms, including via the Company's website.

REPORT ON THE SHAREHOLDERS' MEETING AGENDA

Pursuant to Art. 125-ter of the Consolidated Law on Financial Intermediation, unless otherwise specified by other applicable law, the Board of Directors should make available to the public a report on each item on the agenda, within the same time period for publishing the notice calling the meeting envisaged by virtue of each of the items on the agenda, at the Company's headquarters, on the Company's website and in the other manners set forth by Consob in a regulation.

Reports prepared pursuant to other applicable law are made available to the public in the terms set forth in the same law and the manners indicated above.

RECORD DATE

The record date mechanism applies to participate and vote in a Shareholders' Meeting

With regard to Shareholders' Meeting attendance and voting, the so-called "record date" mechanism applies (Art. 13.2 of the By-laws), which establishes that the right to participate in a Meeting and vote must be certified by a statement submitted by an authorised intermediary on the basis of its accounting records to the Company on behalf of the person entitled to vote.

This statement shall be submitted on the basis of the balances recorded at the end of the seventh trading day prior to the date of the Shareholders' Meeting.

Credit or debit records in the intermediary's accounts after this date have no effect in terms of legitimizing the exercise of voting rights in the Shareholders' Meeting.

⁷⁸ This term is moved back to twenty-one days for Shareholders' Meetings specified in Art. 2446 (reduction of share capital due to financial losses), Art. 2447 (reduction of share capital to below the legal limit), and Art. 2487 (appointment and removal of the liquidators; criteria for the liquidation procedure) of the Italian Civil Code, and to fifteen days for the Meetings provided for by Art. 104 of the Consolidated Law on Financial Intermediation (Defenses in the case of Public Tender Offers).

The Company must receive the statements submitted by the intermediary by the end of the third trading day prior to the date set for the Shareholders' Meeting, or by the date established by Consob regulations, in agreement with the Bank of Italy, without prejudice to legitimate attendance and the right to vote in the event that the certifications reach the Company after the deadline, provided that it reaches the Company by the start of the Shareholders' Meeting at each call.

The Eni By-laws clarify that the record date is determined with reference to the date of the Meeting at first call, provided that subsequent call dates are indicated in the notice at first call; otherwise, it is determined with reference to the individual meeting dates.

TOOLS FOR PARTICIPATING IN AND VOTING AT THE SHAREHOLDERS' MEETING

The Company aims to provide shareholders with tools to facilitate participation in Shareholders' Meetings and exercise the right to vote.

In particular, without prejudice to the possibility of voting by mail in compliance with the law, the following provisions have been set forth in the By-laws:

assignment of Shareholders' Meeting proxies via electronic means79;
electronic notification of the proxies, which the shareholder may do through the appropriate section of the Company's website, in the manner set forth in the notice calling the meeting;
attending Shareholders' Meeting by means of telecommunications systems or voting by mail-in or electronic ballot. The By-laws defer to the notice calling the meeting regarding the instructions on using these telecommunications systems.

Pursuant to Art. 106, paragraph 4, second sentence of Decree Law No. 18/2020 on "Measures to strengthen the National Health Service and to provide economic support for families, workers and businesses related to the epidemiological emergency from COVID-19", as well as Decree Law No. 228/2021, ratified by Law No. 15/2022, which extended the effectiveness of the measures of the aforementioned Art. 106 to the Shareholders' Meetings held by July 31, 2022, the participation of Shareholders in the meeting of May 11, 2022 was carried out exclusively through a Designated Representative, pursuant to Article 135-undecies of the Consolidated Law on Financial Intermediation. In compliance with the provisions of the Decree-Law No. 18/2020, the Designated Representative could be also granted ordinary proxies or sub-delegations pursuant to Article 135-novies of the Consolidated Law on Financial Intermediation (in derogation from Art. 135-undecies, paragraph 4, of the Consolidated Law on Financial Intermediation). The Decree-Law No. 198/2022, ratified by Law No. 14/2023, extended the effectiveness of the aforementioned measures to the shareholders' meetings to be held by July 31, 2023.

DESIGNATED REPRESENTATIVE AND OTHER INITIATIVES FOR SHAREHOLDERS

Furthermore, Eni's By-Laws state that the Company may designate a person (the "Designated Representative") to whom shareholders may grant proxies, with the relevant instructions, for all or some of the proposals on the agenda up until the end of the second trading day prior to the date for the Shareholders' Meeting.

Since the Shareholders' Meeting held in 2011, Eni has made use of its right to appoint a Designated Representative to whom shareholders can freely grant proxies.

In order to simplify proxy voting by shareholders who are employees of the Company and who belong to shareholders' associations that meet applicable legal requirements, the By-

⁷⁹ Pursuant to Art. 135-novies, paragraph 6, of the Consolidated Law on Financial Intermediation, an electronic proxy can be granted via computer document signed electronically in accordance with the Digital Government Code (Legislative Decree No. 82/2005).

laws provide that Eni shall make available to these shareholders' associations locations for communications and collecting proxies, in accordance with the terms and conditions agreed with the legal representatives of said associations.

To ensure that shareholders can exercise the rights established in Eni's By-laws, a special section of the Company's website is dedicated to the Shareholders' Meeting through which it is possible, among other things, to submit questions before the Shareholders' Meeting and provide electronic notification of proxies.

In addition, to make it easier for shareholders to exercise their rights, the simple proxy form, the form used to grant a proxy to the Designated Representative, and the vote by mail forms are available in the special section on the Eni website, together with the relevant documentation and information on providing notification, including electronically, of proxies, granting a proxy to the Designated Representative and vote by mail forms.

In order to stimulate the interest of shareholders and promote a greater degree of involvement in Company life, the Company usually provides a video and a Shareholder's Guide available on its website with clear and direct information on attendance procedures and on the rights that can be exercised at the Shareholders' Meeting.

ADDITIONS TO THE AGENDA AND PROPOSED RESOLUTIONS

Additions to the agenda and proposed resolutions

Pursuant to the law and the By-laws, Shareholders who severally or jointly represent at least one fortieth of the Company's share capital may:

ask for items to be added to the agenda by submitting a request within ten days of publication of the notice calling the meeting, or other term as provided for by the law. The request, which cannot include matters upon which the Shareholders' Meeting must resolve upon a proposal of the Directors or on the basis of a project or report of the Directors, must specify the additional items proposed and must be accompanied by a report to the Board of Directors on the matters proposed for discussion. This report must be made available to the public at the Company's registered office, on the Company's website and as otherwise provided for by applicable regulations, together with any evaluations by the Board of Directors, at the same time as publication of the notice of the additions to the agenda and within fifteen days prior to the date of the Shareholders' Meeting;
submit proposed resolutions on items already in the agenda in the manner and within the time period given for adding items to the agenda.

Proposed resolutions on the items in the agenda may be presented by individual shareholder entitled to vote at the Shareholders' Meeting, even if such shareholders do not meet the share capital threshold indicated above.

Additions to the agenda and proposed resolutions may also be submitted electronically, provided that the shareholder complies with any requirements indicated by the Company in the notice calling the meeting for identifying such shareholder.

Owing to the extraordinary regime applied to the meetings because of the epidemiological emergency from COVID-19, the notices calling the Shareholders' Meetings of May 12, 2021 and of May 11, 2022 provided that, through a specific proxy to the Designated Representative, and exclusively in this way, each person entitled to vote could individually present resolution proposals on the items on the agenda to the Shareholders' Meeting.

The notice also indicated the timing for informing the Company of the intention to present proposals at the Shareholders' Meeting and for the publication by the Company of these intentions on its website, to inform all Shareholders and allow them to give the Designated Representative instructions on how to vote. Shareholders retained the right to use the means of communication at their disposal to make other Shareholders aware of the proposals they intended to present at the Shareholders' Meeting.

SHAREHOLDERS' MEETING RULES

The efficient and orderly running of the Shareholders' Meetings and the right of each shareholder to comment on individual items on the agenda are guaranteed by the Shareholders' Meeting Rules available on the Eni website. The Shareholders' Meeting on May 11, 2022 approved an update to these Rules intended to acknowledge the evolution of legislation and application practice.

QUESTIONS PRIOR TO THE SHAREHOLDERS' MEETING

Questions prior to the Shareholders' Meeting

The Board of Directors strives to ensure timely and easy access to any Company information regarded as important for shareholders so that they may exercise their rights in an informed manner80. Furthermore, those entitled to vote may submit questions on matters on the agenda even before the start of the Shareholders' Meeting.

Any questions received prior to the Shareholders' Meeting shall be answered at the latest during the Meeting itself, including in paper form distributed at the start of the Meeting to those entitled to vote.

The Company may provide a single answer to questions with similar content and is not required to reply when the information is already available in "question and answer" format in the appropriate section of its website.

The notice calling the Meeting indicates the date by which questions must be submitted to the Company: no more than 5 days of open market prior to the Shareholders' Meeting at first or single call, or the above mentioned "record date" if the Company indicates in the notice that it plans to answer questions prior to the Meeting. In the latter case, the answers must be provided at least two days prior to the Shareholders' Meeting and must be published in the appropriate section of Eni's website; the right to exercise voting rights can be certified also after the submission of questions as long as within the third day following the "record date".

Owing to the extraordinary regime applied to the meetings because of the epidemiological emergency from COVID-19, the notices calling the Shareholders' Meetings of May 12, 2021 and of May 11, 2022 provided that the deadline for asking questions on the items on the agenda before the Meeting should be set at the record date, with the Company publishing the reply in a specific section of the website with a longer deadline as set by law (3 days before the Meeting instead of 2), to allow the Shareholders to make a choice and give voting instructions to the Designated Representative. Shareholders retained the right to ask questions directly at the Shareholders' Meeting through the Designated Representative.

Shareholders' Meetings are chaired by the Chairman of the Board of Directors, or in the event of his absence or impediment, by the CEO, or in their absence, by a person named by the Shareholders' Meeting. The Chairman of the Shareholders' Meeting explains the items to be discussed and conducts the Meeting to ensure a regular discussion and that shareholders have the right to comment and receive answers on each item on the agenda, on the basis of the provisions of the Shareholders' Meeting Rules.

3.4.2 APPOINTMENT84

VOTING SLATES

Directors are elected on the basis of slates

To ensure that non-controlling shareholders are represented on the Board, Directors are elected on the basis of slates.

This system has been set out in the Company By-laws since 1994, in compliance with the special rules that apply to the Company itself, envisaged by Art. 4 of Law No. 474/1994. The rule, however, which was amended by Legislative Decree No. 27/2010, with the introduction of paragraph 1-bis of Art. 4, states that during Shareholders' Meetings called after October 31, 2010, the procedure for appointing members of the Company bodies must comply with the provisions established for all listed companies, with the exception of the number of Board members allotted to non-controlling shareholders. Art. 4, paragraph 1-bis, of Law No. 474/1994 confirms that at least one-fifth of the voting directorships (rounded up) must be allocated to slates submitted by non-controlling shareholders.

Eni By-laws reserve to non-controlling shareholders the three-tens of the Board members.

RIGHT TO SUBMIT SLATES

Pursuant to Art. 17 of the By-laws, which were appropriately amended to align its provisions with those of the above-mentioned decree, slates of candidates may be submitted by shareholders85when - either alone or together with others - they represent at least 1% of Eni's share capital or any other threshold established by Consob regulations. Since 2011, and most recently with its decision dated January 30, 2023, Consob set the threshold for Eni at 0.5% of share capital.

Ownership of the minimum holding needed to submit slates shall be determined with regard to shares registered in the name of the shareholder on the date on which the slates are filed with the Company, without considering any subsequent transfer of the shares.

Each shareholder may only submit (or contribute towards submitting) and vote for a single slate. Controlling persons, subsidiaries and companies under common control may not submit or participate in the submission of other slates, nor can they vote on them, either directly or through nominees or trustees.

COMPOSITION, SUBMISSION AND PUBLICATION OF SLATES

Slates must list candidates in numerical order and expressly indicate those who fulfil the independence requirements specified by the law and By-laws. They are filed with the Company's registered office86 at least twenty-five days prior to the date of the Shareholders' Meeting convened to appoint the members of the Board of Directors, and are made available to the public at the Company's registered office, on its website and in any other manner established by law and by Consob regulations at least twenty-one days prior to the Meeting date. Slates of candidates are also communicated to Borsa Italiana SpA.

All candidates must satisfy the integrity requirements established by applicable law.

Together with the filing of each slate, on penalty of inadmissibility, the following shall also be filed: the curriculum vitae of each candidate, statements of each candidate accepting his nomination and affirming the absence of any grounds making him ineligible or incompatible

Requirements for candidates

⁸⁴ Information also provided pursuant to Art. 123-bis, first paragraph, letter l) of Consolidated Law on Financial Intermediation.

⁸⁵ Pursuant to Art. 17.3 of the By-laws, the Board of Directors may submit a slate of candidates.

⁸⁶ In accordance with Art. 147-ter of the Consolidated Law on Financial Intermediation and Eni By-laws, slates may also be filed with the Company using distance communication methods, provided that they comply with any requirements stated by the Company in the notice calling the Meeting that are strictly required to confirm the identity of the submitters.

for such position, and that he satisfies the requirements of integrity and independence required by the law and the By-laws87.

Rules to ensure gender balance in the composition of the Board

Furthermore, in line with legislative provisions, the By-laws of Eni88 provide that at least two fifths of the Board shall consist of directors belonging to the less-represented gender, rounded up, unless the number of members of the Board is equal to three, in which case this number is rounded down. Slates that contain three or more candidates shall include candidates of both genders. The slates competing to appoint the majority of the members of the Board of Directors, made up of more than three candidates, must reserve two fifths to the positions on the slate to the less-represented gender, rounded up.

If the slate voting mechanism does not yield the minimum gender representation required by law, an impartial mechanism is used based upon the number of votes received by the candidates to identify those of the over-represented gender to be replaced by the members of the less represented gender who may be listed on the same slate or chosen by the Shareholders' Meeting.

The shareholders who submitted the slates must also be identified, indicating the percentage of the share capital held89.

Once the voting formalities are satisfied, seven-tenths of the Directors to be elected are drawn from the slate that receives the most votes of the shareholders, rounded off in the event of a decimal number to the next lowest whole number, in the order that they appear on the slate. The remaining Directors are drawn from the other slates, which shall not be connected in any way, directly or indirectly, to the shareholders who have submitted or voted for the slate that receives the largest number of votes90; for this purpose, the votes received by each slate shall be divided by one or two or three depending upon the number of Directors to be elected.

The quotients, or points, thus obtained shall be assigned progressively to candidates of each slate in the order given in the slates themselves. The candidates of all the slates shall be ranked by the points assigned in a single list in descending order. Those who receive the most points shall be elected. In the event that more than one candidate receives the same number of points, the candidate elected shall be the person from the slate that has not hitherto had a director elected or that has elected the least number of Directors.

In the event that none of the slates has yet had a Director elected or that all of them have had the same number of Directors elected, the candidate among all such slates who has received the highest number of votes shall be elected. In the event of equal slate votes and equal points, the entire Shareholders' Meeting shall vote again and the candidate elected shall be the person who receives a simple majority of the votes.

Supplemental mechanisms

If the minimum number of independent Directors required under the By-laws has not been elected following the above procedure, the By-laws provide for supplemental mechanisms to be used.

⁸⁷ It is also requested that the statements indicate whether the candidate satisfies the independence requirements pursuant to the Corporate Governance Code. The Legislative Decree No. 183/2021, in force since December 14, 2021, has supplemented Art. 2383 of the Italian Civil Code, providing that the appointment of a director shall follow the presentation of a declaration certifying the inexistence, for the candidate director, of the causes of ineligibility provided for by article 2382 of the Italian Civil Code and disqualifications from the office of Director adopted in a Member State of the European Union. Pursuant to Art. 2382 of the Italian Civil Code, the interdict, the disabled person, the bankrupt, or whoever has been sentenced to a penalty that implies the interdiction, even temporary, from public offices or the inability to exercise direct offices cannot be appointed director, and if appointed lapses from his office. 88 See Articles 17 and 34 of the Company By-laws. The By-laws, first amended in 2012 to incorporate the provisions on gender balance established by Law No.

^{120/2011 –} according to which the less represented gender must obtain, in the first term, at least one fifth of appointed directors and at least one third in the two subsequent terms, starting from the first appointment of corporate bodies after August 12, 2012 – have been modified by resolution of the Board of Directors of February 27, 2020 to adjust to the new regulatory provisions on the matter, pursuant to Law No. 160/2019 which reserves at least two fifths of the Directors to the less represented gender. The provisions aimed at ensuring compliance with current legislation on gender balance shall apply to six consecutive terms of the Board of Directors from the first appointment after January 1, 2020.

⁸⁹ In addition, in the case of slates filed using distance communication methods, the requirements for confirming the identity of the submitters as specified in the notice calling the Meeting must be satisfied.

⁹⁰ The criteria for connection are set out in Art. 144-quinquies of the Consob Issuers' Regulation.

If, for any reason, including not being able to seat a full Board through slate voting, Directors are not appointed using this procedure, the Shareholders' Meeting shall resolve, with the required legal majorities, so as to ensure that the composition of the Board is compliant with the law and the By-laws.

The slate voting procedure shall apply only to the election of the entire Board of Directors.

Pursuant to Art. 2386 of the Italian Civil Code, referred to in Art. 17.5 of the Eni By-laws, if during the year one or more positions on the Board are vacated, the other members shall replace them with a resolution approved by the Board of Statutory Auditors, as long as the majority of the remaining Directors have been appointed by the Shareholders' Meeting. The Nomination Committee proposes candidates to serve as Directors to the Board, ensuring compliance with the requirements concerning the minimum number of independent Directors and the percentage reserved to the less represented gender. The Directors so appointed shall remain in office until the subsequent Shareholders' Meeting, which shall either confirm the appointment or appoint other Directors.

If a majority of the Directors should vacate their offices, the entire Board shall be considered to have resigned, and the Board shall promptly call a Shareholders' Meeting to elect a new Board.

3.4.3 SUCCESSION PLAN FOR EXECUTIVE DIRECTOR AND KEY PERSONNEL

With reference to plans for the succession of Executive Directors, the Nomination Committee has been entrusted by the Board of Directors with the task of supporting it in the preparation, updating and implementation of the succession plan for the CEO, identifying, as a minimum, the procedures to following the event of early termination.

At its meeting of February 17, 2015, after reviewing the Nomination Committee's evaluation, the Board of Directors decided not to prepare a succession plan for the CEO given the current shareholding structure of the Company. However, it decided upon a contingency plan, which sets out the steps to be taken in the event the CEO is unexpectedly unable to perform his duties. On April 7, 2022, the Board of Directors reviewed the "contingency plan", based on the preparatory work done by the Nomination Committee, and updated it to take into account the new organisational structure of the Company.

In particular, the "contingency plan" provides for communication to the market of the event that determines its activation and the convening of the Board of Directors for the temporary reassignment of the managerial powers of the CEO to the two Chief Operating Officers91, as well as the activation of dialogue by Chairman of the Board of Directors with the shareholder of reference for any indications also in relation to co-option.

The process and methodology for the succession plans for those holding key positions, including the plans for those positions that Eni's Board of Directors is responsible for appointing, have been used at Eni since 2012.

The process, which was presented on several occasions to the Nomination Committee starting in 2012, is managed by Eni's competent Human Resources functions with the support of an external consultant, in particular for the aspects of methodological updating and for the activities that imply a comparison with the market.

The "contingency plan" in the event the CEO is unexpectedly unable to perform his duties

⁹¹ The Chief Operating Officers already hold powers nearly coinciding with those of the Chief Executive Officer for the relevant sector.

In 2022 the Nomination Committee addressed the issue of succession plans for key strategic positions and roles, reporting on their findings to the Board of Directors, considering the following:

analysis of the process and methodology used;
KPI analysis first line CEO and other relevant positions, including second line;
application of the succession planning methodology for positions and roles, falling within the competence of the Committee, which have been subject to appointment during the year.

3.4.4 INDEPENDENCE REQUIREMENTSTHE LAW AND BY-LAWS

THE LAW AND BY-LAWS

The Consolidated Law on Financial Intermediation establishes that at least one Director, or two if the Board is comprised of more than seven members, must satisfy the independence requirements for Statutory Auditors of listed companies as set out in Art. 148, paragraph 3 of that law, as well as any other requirements set out in codes of conduct if the By-laws so provide.

Art. 17.3 of Eni's By-laws improve on the existing law by establishing that at least one Director, if there are no more than five Directors, or at least three Directors, if there are more than five, shall satisfy the independence requirements. The same article also provides for a mechanism beyond the ordinary election system for ensuring that the requirement of a minimum number of independent Directors is satisfied. By doing so, Eni seeks to strengthen the presence of independent Directors on its Board.

CORPORATE GOVERNANCE CODE RECOMMENDATIONS

The requirements established by Corporate Governance Code

Principle VI of the Corporate Governance Code also recommends that a significant number of non-executive Directors should be independent, meaning that they do not maintain, nor have they recently maintained, directly or indirectly, any relationships with the Company or persons linked to the Company of such a significance as to influence the current autonomy of judgment (see definition of "independent directors" in the Code). The number and competences of independent Directors must be adequate to the Company's needs and to the operation of the Board, as well as the establishment of Board Committees (Recommendation 5 of the Code).

The Code recommends that in "large companies" other than those with concentrated ownership92, like Eni, independent directors account for at least half of the Board (Recommendation 5)93.

Recommendation 7 of the Corporate Governance Code lists some circumstances that compromise, or appear to compromise, the independence of a director.

The general principle expressed in the introduction of the Code is also applicable to this Recommendation, according to which companies adopt the Code with prevalence of substance over form and apply its Recommendations according to the "comply or explain" criterion.

ENI SPECIFICATIONS

Since 2006, when previous versions of the Corporate Governance Code were in force, Eni's Board of Directors has specified recommended independence criteria for Directors. In particular, for the purposes of the assessment of independence following the appointment of

The requirements established by law and By-law

⁹² The Code clarifies that a "large company" is a company whose capitalisation was greater than €1 billion on the last exchange business day of each of the previous three calendar years. "Companies with concentrated ownership" are companies in which a single shareholder (or a plurality of shareholders which participate in a shareholders' voting agreement) holds, directly or indirectly (through subsidiaries, trustees, or third parties), the majority of the votes that can be exercised in the ordinary shareholders' meeting.

⁹³ This Recommendation applies starting from the first renewal of the Board of Directors after December 31, 2020.

the Board, carried out in May 2020, in relation to the then-in-force 2018 Corporate Governance Code:

"subsidiaries with strategic importance" were identified in Eni International BV and Versalis SpA;
the amount of "additional remuneration" that could compromise the independence of a nonexecutive Director has been established in the amount of 30% of "fixed remuneration"94;
"close relative" was defined to include spouse, relatives and relatives-in-law within the second degree of kinship;
the criterion that gives relevance to transactions with related parties as a criterion for assessing the significance of relationships that may compromise the independence of a director (excluding transactions of small amounts, as well as ordinary transactions carried out at market or standard conditions) was confirmed.

In the assessment of the independence requirements pursuant to the Corporate Governance Code, carried out on April 1, 2021, the Board pre-defined, in line with recommendations of the Code, the qualitative and quantitative criteria for assessing the significance of the relationships and additional remuneration which may compromise independence, indicated in Recommendation 7, letters c) and d), of the Code, confirming the procedures already in place, as well as the criterion identifying the "subsidiaries with strategic importance", for the purposes of Recommendation 7, letter b), as those indicated in the resolution on reserved powers of the Board of May 14, 2020, namely Versalis SpA and Eni International BV. Following the Board resolution on May 26, 2022, the aforementioned companies were also joined by Eni Plenitude SpA Società Benefit. As for the definition of "close relatives", referred to in Recommendation 7, letter h), it established to refer to the list contained in the related Q&A, which considers "close relatives" parents, children, spouses who are not legally separated and cohabitants.

Upon the assessment of the requirements, carried out on February 17, 2022, the Board, with the support of the Nomination Committee, approved the modification of the criteria applicable to the significance of relationships, pursuant to Recommendation 7, letter c) of the Corporate Code Governance. In particular, following the entry into force of the new MSG "Transactions involving the Interests of the Directors and Statutory Auditors and Transactions with Related Parties", on July 1, 2021, to ensure compliance with new Consob regulations on the matter, certain subjects previously declared by Directors as "Related Parties", whose relations with Eni underwent a specific assessment upon previous independence checks, are now classified as "subjects of interest" and therefore would no longer be subject to assessment for the purposes of their significance. The Board therefore established that in order to assess the significance of commercial, financial or professional relationships, reference should be made not only to transactions with related parties but also with subjects of interest or close relatives not included in related parties, but relevant for Corporate Governance Code, above the minimum threshold and excluding ordinary transactions carried out at market or standard conditions, as defined by the MSG "Transactions involving the Interests of the Directors and Statutory Auditors and Transactions with Related Parties".

Furthermore, taking into account assessments made in the previous audits and the choices made by some listed companies for the purposes of evaluating relations with respect to their impact on the turnover of the parties concerned, the Board made it clear that the significance of these relations may be attenuated or excluded at the occurrence of at least two of the following circumstances: (i) the pre-existence of the relationship with respect to the appointment in Eni; (ii) incidence of the relationship with Eni lower than 5% of the annual

⁹⁴ The Board also clarified that the compensation paid to the Directors for serving on the Sustainability and Scenarios Committee is not treated as additional remuneration for independence purposes, as it is for the other Committees envisaged by the Code (Art. 3.C.1 letter d) of the 2018 Corporate Governance Code).

turnover95 of the company controlled by the director or of which the director (or a close relative) is an executive director or of the professional firm or consultancy company of which the director (or a close relative) is a partner; (iii) termination of the relationship before the beginning of the term or no later than six months from the beginning of the term.

BOARD ASSESSMENTS

Board assessment

The Board of Directors assesses the independence of Directors, after periodical verification by the Nomination Committee, based on the criteria established by the Consolidated Law on Financial Intermediation and on the requirements set forth in the Corporate Governance Code.

Upon appointment, and annually thereafter, and where necessary owing to events that could affect independence, the non-executive Directors must provide statements that they satisfy the independence requirements and the Board assesses the independence of these Directors, taking account of all the above criteria and prioritizing substance over form, as required by the Corporate Governance Code. The Nomination Committee is responsible for enquiries connected with the Board's verification that the Directors satisfy the independence requirements.

In particular, on May 14, 2020, shortly after its appointment, the Board of Directors, on the basis of statements made by the Directors and other information available to the Company, determined that Chairman Calvosa and Directors De Cesaris, Guindani, Litvack, Piccinno, Tocci and Vermeir satisfy the independence requirements established by law, as referenced in Eni's By-laws. Furthermore, Directors De Cesaris, Guindani, Litvack, Tocci and Vermeir were deemed independent by the Board pursuant to the criteria and parameters then recommended by the 2018 Corporate Governance Code. Chairman Calvosa, in compliance with the 2018 Corporate Governance Code, could not be deemed independent as she is a key officer of the Company96.

Following adoption of the Corporate Governance Code, on April 1, 2021, the Board of Directors, after preliminary assessment by the Nomination Committee:

(a) confirmed the previous assessment that the Chairman and Directors De Cesaris, Guindani, Litvack, Piccinno, Tocci and Vermeir meet the independence requirements provided for by law;

(b) confirmed the Board's previous assessment that the Directors De Cesaris, Guindani, Litvack, Tocci and Vermeir meet the independence requirements recommended by the Corporate Governance Code;

(c) assessed the Chairman of the Board of Directors as independent, also pursuant to the new Code which, innovating with respect to the previous edition, provides that the Chair, who was presented as a candidate to such role by those presenting a list for the appointment of the majority of the body, can be assessed as independent if none of the circumstances indicated by Recommendation 7 occurs.

The Board of Directors of February 17, 2022, on the basis of the statements made by the Directors and the inquiry carried out by the Nomination Committee, confirmed:

(a) that the Chairman and Directors De Cesaris, Guindani, Litvack, Piccinno, Tocci and Vermeir satisfy the independence requirements established by law;

(b) that the Chairman and Directors De Cesaris, Guindani, Litvack, Tocci and Vermeir satisfy the independence requirements set forth by the Corporate Governance Code, considering in particular as non relevant, with reference to Recommendation 7, letter c) of the Code, based on predefined criteria of the Board, the relations between Eni and: (i) the law firm, of which a relative of Director De Cesaris is a partner, already subject to assessment by the Board on

April 1, 2021 which had ruled out its significance97; (ii) the Istituto Affari Internazionali (IAI), of which the Director Tocci is Director, a position considered similar to that of an executive director for the purposes of the Code, already subject to evaluation by the Board on April 1, 2021 which had ruled out its significance98. Furthermore, it has assessed Director Piccinno as independent also pursuant to the Corporate Governance Code. To this end, by applying the criteria for assessing the relevance of relations pursuant to Recommendation 7, letter c), considered as non relevant the terminated collaboration between the Director and the Ministry of Economic Development, having regard to the preexistence of the relationship with respect to the office in Eni and the interruption of the same before the beginning of the term, as well as the circumstance of the change of political subjects with whom he collaborated.

The Board of Directors of February 22, 2023, on the basis of the statements made by the Directors and the inquiry carried out by the Nomination Committee, confirmed: that the Chairman of the Board of Directors and Directors De Cesaris, Guindani, Litvack, Piccinno, Tocci and Vermeir meet the independence requirements specified by the law and by the Corporate Governance Code. In particular, based on the criteria defined by the Board of Directors, the significance of the relations between Eni and the parties related to Directors De Cesaris and Tocci was ruled out, as already verified in previous assessments.

The Board of Statutory Auditors always verified the proper application of the criteria and procedures adopted by the Board in assessing the independence of its members. The assessments of the Board are reported in the tables attached to this Report.

3.4.5 INTEGRITY REQUIREMENTS, REASONS FOR INELIGIBILITY AND INCOMPATIBILITY

The Consolidated Law on Financial Intermediation specifies that individuals who perform management and administration functions in listed companies must fulfil the integrity requirements established for members of control bodies in the guidelines issued by the Minister of Justice pursuant to Art. 148 of the Consolidated Law on Financial Intermediation99.

In particular, Art. 17.3 of the By-laws, in transposing this provision, establishes that all candidates for the position of Director must fulfil the integrity requirements specified in current regulations. In addition, the Directors are required to fulfil additional specific requirements established by any special rules applicable to them.

The same provision also requires the Board to periodically evaluate the independence and integrity of Directors and ascertain the absence of circumstances that would render them ineligible or incompatible.

Pursuant to Art. 17.3 of the By-laws, if a Director does not or no longer satisfies the independence and integrity requirements declared and established by law or if circumstances arise that render him ineligible or incompatible, the Board shall declare that the Director has forfeit the position and replace him, or shall invite him to rectify the circumstances rendering him incompatible by a deadline set by the Board itself, on penalty of forfeiture.

Upon appointment and thereafter on a periodic basis, the Directors are required to issue statements that they satisfy the integrity requirements under applicable law, as well as the absence of grounds for ineligibility, incompatibility or forfeiture100, and the Board verifies that the integrity requirements have been satisfied, in accordance with current regulations. The appointed Directors must notify the Company if they should no longer satisfy the independence and integrity requirements or if cause for ineligibility or incompatibility should arise.

3.4.8 MEETINGS AND RUNNING OF MEETINGS

Board Rules

At the meeting held on May 14, 2020, the Board of Directors approved the Rules on its operation and organisation, including the procedures for calling and running its meetings. These Rules were most recently amended in the meeting of December 16, 2021, also for the purpose of adapting to the Corporate Governance Code.

In particular, the notice of the meeting, signed and prepared by the Chairman having examined the proposals of the Chief Executive Officer, contains the location of the meeting; the locations where it is possible to participate in the meeting by videoconference or any other forms of connection; date and time of the meeting; the items on the agenda, specifying which items will be subject to a resolution and which are simply meant to provide information.

The notice of the meeting is sent by the Board Secretary, normally at least five days prior to the date of the meeting or, when necessary and urgent, at least twelve hours in advance of the time set for the meeting, to the Directors, the Standing Statutory Auditors and to the Magistrate of the Court of Auditors ("Corte dei Conti") appointed to monitor the financial management of the Company and his or her substitute.

Normally, at the same time the notice calling the meeting is sent and, in any case, no more than three days prior to the date of the meeting, the Board Secretary makes available any documentation relating to the items on the agenda to the Directors, Standing Statutory Auditors and the Magistrate of the Court of Auditors on a digital Platform reserved for the Board of Directors. Access to the Platform is restricted by the use of personal credentials, assigned to each Director, Statutory Auditor and the Magistrate of the Court of Auditors (with a view to preserving the confidentiality and security of information). The documentation may be sent, upon request by the individual members of the Board and if there are justified reasons, to their e-mail addresses.

In accordance with the provisions of the Corporate Governance Code, a summary sheet of the items on the agenda is prepared for each meeting. When, in relation to individual topics, the documentation made available is particularly complex and voluminous, it shall be accompanied by a document summarizing the most significant and relevant points for the purposes of the decisions on the agenda.

If, in specific cases, it is not possible to provide the necessary information within three days before the date of the meeting, the Chairman ensures that adequate and detailed analyses are carried out during the Board sessions.

During the year, the deadline of three days before the date of the meeting, provided for by the Rules, for sending the documentation relating to items on the agenda subject to Board approval was substantially respected, except for the exceptions related to the need to submit accounting or planning documents updated on the date closest to that of the Board's meeting and approval, or supporting documentation relating to transactions whose negotiation continued until the date of the Board or to urgent topics that emerged subsequently. In such cases, the Chairman made sure that the necessary details were provided during the Board sessions, asking the company structures to specifically focus, during the presentation to the Board, on the documentation received after the aforementioned three-day deadline, in order to allow Directors to deliberate in an informed and aware manner.

Information to Directors: the role of the Chairman

The Chairman ensures the effective working of the Board and, in her role of liaison between executive and non-executive directors, ensures, with the assistance of the Secretary, the

timeliness and adequacy of the pre-Board information submitted or transmitted to the Board, as well as the complementary information provided during the meetings, and that the same is suitable to enable the Directors to perform their duties in an informed manner. For this purpose, the Chairman can ask the CEO for appropriate changes or additions.

The By-laws allow Board meetings to be held via videoconferencing and teleconferencing, and these procedures are specifically governed in the Rules.

In agreement with the CEO and with the help of the Board Secretary, the Chairman ensures that the managers of the Company and of Group companies responsible for the relevant corporate functions connected with the items to be discussed attend the Board meetings, also at the request of individual directors, to provide appropriate in-depth information on the items on the agenda111.

In accordance with the provisions of Art. 2391 of the Italian Civil Code, the Rules of the Board of Directors and the internal regulations governing "Transactions involving the Interests of the Directors and Statutory Auditors and Transactions with Related Parties"112, before each item on the Board meeting's agenda is discussed, each Director is required to disclose whether he holds any personal interest or interest on behalf of third-parties in relation to the matters or issues to be discussed, clarifying their nature, terms, origin and extent. During Board resolutions, Directors holding an interest in issues to be deliberated upon do not normally take part in the discussion and resolution, leaving the meeting room.

In 2022, the Board of Directors met 16 times, each meeting lasting an average of 3 hours and 38 minutes and with an average participation of 97.9% of the Directors. During the year, the meetings were, as a rule, always held at the registered office or at other offices of the company, with the possibility of connecting in audio and video conferencing via office equipment.

The table accompanying this Report shows the number of Board meetings attended by each Director.

In 2023, as of March 16, 2023 included, there have been 4 meetings. Another 10 meetings are expected to be held before the end of the year.

During the year, independent Directors, coordinated by the lead independent director appointed in April 2021, met on March 16, 2022 and on July 28, 2022 and, taking into account the frequency of the Board meetings, they had further informal opportunities to meet and exchange views, thoughts and ideas, in compliance with the Recommendations of the Corporate Governance Code.

Pursuant to the Stock Exchange Rules, a public announcement is made within 30 days of the close of the previous financial year of the annual calendar of events (the "financial calendar"), specifying, among other things, the dates of the Board of Directors meetings called to examine the draft annual financial statements and interim financial reports required by applicable regulations, any preliminary financial statements and any other additional periodic financial disclosures113, as well as the date of the Shareholders' Meeting to approve the financial statements for the year; the announcement also includes the dates of Board meetings called to determine the dividend distribution, accompanied by the associated distribution and ex-dividend dates.

3.4.10 BOARD REVIEW AND GUIDELINES FOR SHAREHOLDERS ON THE COMPOSITION OF THE BOARD OF DIRECTORS

BOARD REVIEW FOR 2022

With regard to 2022, in accordance with the international best practices and the provisions of the Corporate Governance Code, the Board of Directors launched, for the seventeenth year in a row, a 2022 Board Review for the Board of Directors and its Committees, availing itself, as usual and in line with the application modalities of the Code adopted by Eni, of the external consultant Crisci & Partners to ensure objectivity in the process114.

In compliance with the Recommendations of the Corporate Governance Code, the Chairman of the Board of Directors has the task of ensuring the adequacy and transparency of the Board Review process, with the support of the Nomination Committee and the assistance of the Board Secretary.

For 2022, the Chairman of the Board of Directors, with the support of the Nomination Committee, through its Chairman, and with the assistance of the Board Secretary, decided with the consultant the procedures for carrying out the assignment, in continuity with the previous year. For 2022 it was decided not to proceed with the peer review (unchanged since 2021).

The Board Review process, starting from November 2022, took place through questionnaires and interviews concerning in particular: (i) the size, functioning and composition of the Board and the Committees, also taking into account elements such as professional characteristics, experience, including in management, and diversity, including gender, of its members, as well as their seniority in office; (ii) the strategic and monitoring role of the Plan, including ESG issues and the internal control system and risk management . The advisor was asked, among other things, to take into account the recommendations of the Italian Corporate Governance Committee in the letter of the Chairman of the Committee in January 2023115.

The review activity carried out for 2022 concluded at the meeting on February 22, 2023 with the presentation of the results of the process by the consultant. Confirming the positive elements already emerged from previous Board Review, the presentation highlighted in particular a positive evolution in:

the mix of knowledge, experience and expertise acquired in relation to the businesses, scenarios, the Plan's strategic and monitoring role, the sectors in which the Company operates and associated risks;
the effective supporting role of the Board of Directors in the process of energy diversification, transition and security, topics that characterised the Board's work for its entire term, in addition to the commitment and time spent on ESG issues, sustainability and the energy transition and on the adequate adoption of ESG principles into the Company's policies;
the functioning of the Board of Director in terms of individual commitment dedicated to the role and in terms of efficacy of the joint proceedings, considered balanced, competent

¹¹⁴ In the meeting of October 28, 2020, the Board approved the proposal of the Nomination Committee to assign Crisci & Partners the task of providing assistance on the Board Review for the 2020-2022 term, delegating the Chairman to discuss with the consultant the procedures for carrying out the assignment. ¹¹⁵ For more information, please refer to "Observations on the letter of January 2023 of the Chairman of the Italian Corporate Governance Committee" in the section "Compliance with the Corporate Governance Code" of this Report.

The Board guidelines and the opinion of the Nomination Committee and contributing, also by virtue of the effective consultation and investigation support from the Board Committees;

the role performed by the Chairman of the Board in ensuring the correct function of the Board and the organisation of board meetings, in particular for the timeliness, completeness and quality of the documentation made available;
the role and actions of the CEO, recognised for his excellent capacity for vision, innovation and entrepreneurship, significant authority in leading the company, and managerial skills, including in light of the important steps taken in the process launched for the overall and transformative energy transition;
the role of the Committees, leadership of the Chairmen and contribution made to the Board, also recognised by the time and attention dedicated to them within the Board;
support provided by the Board Secretary and its structure, for the contribution to the effective organisation of proceedings and for the clarity and completeness of minute taking in board meetings;
induction activities, in terms of both scope and quality of the topics addressed.

With particular reference to induction and onboarding activities, also considering the positive assessment emerging from the Board Review, the Board recommends that, in the next mandate, training activities continue for the benefit of directors, especially on issues relating to the implementation and updating of the strategic and energy transition plan.

The consultant Crisci & Partners, in their capacity as facilitators of the Board Review of the Board of Directors of Eni for the year 2022, and on the basis of the positive perceptions and opportunities for discussion, achieved with each member of the Board during the Board Review process, share the analysis of the Directors.

This is further confirmed by their having detected a timely and excellent level of overall compliance of Eni's Board governance with the provisions of the Corporate Governance Code. The consultants from Crisci & Partners share the analysis put forward by the Directors relating to the consolidation of their mutual knowledge and social skills, the assessments of appropriate experience and expertise and the size and composition of the Board, associated with its functioning and the requirements of the existing term.

GUIDELINES TO SHAREHOLDERS ON THE COMPOSITION OF THE BOARD OF DIRECTORS

As recommended by the Corporate Governance Code, in view of the renewal of the corporate bodies, Eni's Board of Directors, with the assistance of the Nomination Committee and taking into account the results of the Board Review, prepared its guidelines on the quantitative and qualitative composition of the board of directors it considers to be optimal. The guidelines, approved by the Board on February 22, 2023, was published on the Company's website on March 6, 2023 to ensure publication within an appropriate period before the notice of the Shareholders' Meeting, for the benefit of the shareholders.

See below for the guidance published on the Company's website.

Preliminary Summary

The Board of Directors of Eni SpA, whose term of office expires with the approval of the financial statements for the year 2022, in compliance with the recommendations of the Corporate Governance Code (hereinafter referred to as CGC), in view of the renewal of the corporate bodies, submits to the Shareholders its Guidelines on the quantitative and qualitative composition deemed optimal for the Board of Directors116, taking into account the results of the Self-Assessment, carried out on an ongoing basis throughout the entire term of office.

¹¹⁶ The Corporate Governance Code recommends that shareholders that submitting 'a list containing a number of candidates exceeding half of the members to be elected' are required 'to provide adequate information, in the documentation submitted for the filing of the list, on the consistency if the list with the guidelines expressed by the Board of Directors, also with reference to the diversity criteria set forth in Principle VII and Recommendation 8, and to indicate their candidate for the office of Chairman of the Board of Directors, whose appointment shall be made in accordance with the procedures set forth in the Article of Association'.

The Guidelines provided by the outgoing Board come at the end of a term marked by numerous factors of significant strategic importance and transformative scope, not only with reference to the company but also the industry and the international context in which it operates.

The members of the Board emphasise that the company has in fact embarked on a major energy transition path, aimed at 2050, which has seen the development of three business plans, characterised by particularly ambitious and bold transformation goals.

In this process of change, the incumbent Board believes it has responsibly and competently fulfilled its role of strategic guidance, actively promoting and sharing objectives and constructively supporting the CEO and the entire management team in the process of diversification, transition and energy security which, moreover, began at a time strongly affected by both the impacts of the pandemic crisis and the more recent war and the consequent geopolitical and economic impacts.

The Board holds that it has achieved an important level of understanding of the complex management issues, developing significant experience and expertise in dealing with and making decisions on the topics addressed, thanks to the contribution of the professional skills and commitment and dedication devoted to the role by each Director, and also to the effectiveness of the collegial, balanced, competent and contributory work done.

The evaluations expressed emphasise the importance of guaranteeing, in the composition of the future Board, adequate continuity and the level of performance achieved, in order to ensure that the company continuously and constantly exercises its governance and policy-making functions through the Board of Directors, particularly in this extraordinarily complex and evolving economic situation, and taking into account the medium-long term industrial cycle that characterises the energy sector.

To that end, it is useful to point out that, as a result of reaching the three-mandate limit, two Directors currently in office, drawn from the minority list, will lose their Independence requirement, thus making it foreseeable that they will be replaced, and this already represents a factor of substantial change.

Context

During its 2020 - 2022 term of office, Eni's Board of Directors has, in a cohesive manner, discussed, resolved and implemented activities of significant strategic, economic and financial importance for the Company and for the national system, together with initiatives aimed at ensuring the maximum effectiveness of governance structures, summarised below:

− Confirmation of the determination and awareness of the values that inspire Eni's purpose to arrive at a fair and inclusive energy transition, with the aim of preserving the planet and promoting access to energy resources in an efficient and sustainable manner for all, without neglecting the implementation of that necessary to guarantee energy security.
− Definition of a Strategic Plan, updated annually, which has seen the acceleration of the decarbonisation strategy with the goal of reducing all emissions to zero by 2050 and which has been progressively adapted to the changed macroeconomic context, further complicated by the Russian invasion of Ukraine and the consequent geo-political and economic impacts, and the new energy security requirements, aimed at guaranteeing the supply of additional gas volumes for Italy and Europe.
− Approval of a new organisational structure for the Company (with the establishment of two new general divisions: Natural Resources and Energy Evolution) and a new business model (so called "satellite") that envisages the establishment of companies dedicated to the generation, transformation and sale of sustainable energy products, obtained from renewable sources, biomass and decarbonised processes.
− Full integration of environmental and sustainability objectives into company strategies and policies, accompanied by the inclusion of sustainability parameters, also in remuneration policies.
− Continuous effort to expand in-house expertise on safety issues - operational, health & safety and cyber - also with specific Induction programmes.
− Definition and updating of a dividend policy aimed at sharing with investors the value generated through Eni's progress on its strategic path accompanied by modular buy-back programs;
− Significant operations in the development of proprietary frontier technologies, such as the magnetic confinement fusion project.
− Adoption of the best compliance and governance practices, also in compliance with the principles and recommendations of the CGC approved in 2020 by the Italian Corporate Governance Committee (of which Eni's Chairman is President), to which the company has adhered since 1 January 2021.

Size

The current size of the Board of 9 members (the maximum number established by the Articles of Association) remains optimal, and the Board recommends its continuation, allowing for the effective composition of the internal Board Committees and the important working contribution they offer to the strategic supervision role exercised by the Board, also thanks to the variety of skills and consolidated experience offered by the Directors.

The fact that independent directors represent a majority of the Board (currently 7 out of 9, including the Chairman) as defined under the law and the CGC is also an element to be favoured.

Diversity and Tenure

With reference to the various types of diversity currently represented - gender (4 women and 5 men), age (average 59, median 61), professional background (managers, professionals, academics) and geographical origin - the Board expresses positive assessments overall. The guidelines given are to maintain, and possibly expand, a balanced and diverse variety of skills, abilities and experience, also in the future composition. The Board recalls that, pursuant to Article 17.3 of Eni's Articles of Association, at least two-fifths of the Board must consist of directors of the less represented gender, rounded up to the next whole number.

With reference to tenure in office, the guidance expressed by the Board confirms the importance of not wasting the skills and experience acquired and consolidated in the current term, taking into account that a good 6 out of 9 Directors are in their first term and that 2 of the 3 Directors taken from the minority list will in any case have to be replaced due to having served for 3 terms, the maximum limit for continued recognition as independent.

Experience – Knowledge – Skills

In the 2022 Self-Assessment, the Board of Directors, as anticipated, emphasised the need to ensure the continuity necessary to implement the strategic guidelines and operational and organisational projects, in order to achieve and consolidate results and meet Eni's strategic and management objectives.

The Board of Directors, based on experience acquired through work completed and the scale of the challenges that will have to be faced in the new term to continue the path towards a just transition, combined with the requirements of energy security, recommends a composition that ensures high skills in differentiated areas are included, with experience and expertise that confirm and appropriately complement the qualitative composition of the Board.

In addition to full independence of judgement and accountability, the main requirements, in terms of distinctive experience, knowledge and skills, which the Board deems appropriate for all directors are:

− Knowledge of the regulatory framework and governance mechanisms of listed companies and awareness of the Board of Directors' strategic guidance role in complex multinational industrial realities, acquired through experience on Boards of Directors of listed companies of a complexity comparable with that of Eni;
− Knowledge of sustainability issues and the climate and environmental risk control, acquired through managerial or entrepreneurial roles and in industrial contexts comparable to those in which Eni operates;

− International experience and knowledge of energy markets and the socio-political realities of the countries in which Eni operates.

Soft skills

The Board also assigns particular importance to 'soft' skills, with the main ones listed below:
− Analytical, prioritisation and decision-making skills;
− Social intelligence (listening, collaboration, dialogue and communication skills);
− Awareness of the importance of the role and responsibilities;
− Authoritativeness and ability to share professional expertise and opinions.

Should the Shareholders opt for a substantial change in the composition of the Board of Directors, it is emphasised that it is important for new Directors to be willing and motivated to follow a robust and structured onboarding programme, in order to minimise the time required to be able to fully exercise their role and contribute to the Board's task of strategic oversight.

Availability of Time

All candidates for future Eni Board Members must give full evidence guaranteeing the availability of the time necessary to participate, physically or possibly through video-conference, and to prepare for Board meetings (16 in 2022, for an average duration of more than 4 hours) and Committee meetings, as well as to participate in onboarding/induction sessions and, during their term of office, in ongoing training sessions, as well as in meetings, also off-site, with other Board Members.

In addition to the time required to attend meetings, it is also necessary to add the significant time (which can be estimated at between two and three times the scheduled meeting time) spent preparing for each meeting and, for the Chairpersons of the Board and each of the Committees, also the time dedicated to carrying out the role and activities of preparing, organising and coordinating Board and Committee meetings.

Roles of Particular Importance

Eni's Directors, aware of the high importance of certain roles within the Board of Directors, indicate the main specific characteristics of the representatives called upon to fill those roles:

Chairman of the Board of Directors

be a figure with a high professional and value profile, independent, authoritative and credible, so as to play the role of guarantor towards Eni's shareholders and stakeholders;

During the year, documentation relating to the items on the agenda was made available to the members of the Committee in almost all cases within the terms and in the manner provided for by the Committee Rules. In some limited cases it was not possible to comply with these time limits, for reasons mainly related to the need to ensure that the documentation submitted to the review of the Control and Risk Committee was as updated as possible (also taking into account the large advance with which the Committee meets with respect to the Board). In any case, the Chair of the Committee always ensured that adequate information was provided during the meeting, ensuring in particular that detailed illustrations of the topics were provided by the representatives of the competent company functions and stimulating discussion on the same topics, so that the members of the Committee could act in an informed and aware manner.

3.8.3 PROFESSIONAL, INTEGRITY AND INDEPENDENCE REQUIREMENTS: CAUSES FOR INELIGIBILITY, INCOMPATIBILITY AND FORFEITURE

Requirements pursuant to law and Corporate Governance Code

Pursuant to the Consolidated Law on Financial Intermediation, the Statutory Auditors must meet specific independence requirements, as well as experience and integrity requirements, as established in the regulations issued by the Minister of Justice in agreement with the Minister of the Economy and Finance144. In addition, the Corporate Governance Code which Eni adopted also recommends that all members of the control body possess the independence requirements envisaged by Recommendation 7 for Directors (Recommendation 9 of the Code)145. Independence is assessed by the Board of Statutory Auditors with the timing and methods provided for in Recommendation 6 of the Code, based on the information provided by each member of the body. The assessment is sent to the Board of Directors.

With reference to professional requirements, Art. 28 of the By-laws states that - as established in the above ministerial regulations - the requirements may also be met through professional or teaching experience (of at least three years) in the commercial law, business economics and corporate finance fields, or through the exercise of management functions (for at least three years) in the engineering and geology fields.

In addition, all of the Statutory Auditors currently in office are entered in the register of certified auditors.

The Statutory Auditors in office declared for the first time that they fulfilled the independence, integrity and professional requirements set forth in the applicable regulations upon their appointment by the Shareholders' Meeting of May 13, 2020; as to Statutory Auditor Marcella Caradonna this happened upon appointment by the Shareholders' Meeting of May 12, 2021.

After their appointment, and following the takeover of the Statutory Auditor Marcella Caradonna, the Board of Statutory Auditors verified that the above requirements were satisfied, including those related to the criteria of the Corporate Governance Code regarding independence of Directors. The Board of Directors made their own verifications at the meeting held on May 14, 2020 after the appointment by the Shareholders' Meeting and on May 27, 2021 following the appointment of Statutory Auditor Marcella Caradonna. The results of the assessments were disclosed after the appointment of the Board of Statutory Auditors by means of a press release to the market. Periodic verification of requirements

¹⁴⁴ Regulation containing the guidelines for establishing the professional and integrity requirements for members of the Board of Statutory Auditors of listed companies, issued in accordance with Art. 148 of Legislative Decree No. 58 of February 24, 1998 set forth in Decree No. 162 of March 30, 2000.

¹⁴⁵ The independence requirements for Directors contained in the Corporate Governance Code are described in the sections of the Report specifically on the adoption of the Code and the requirements for Directors. With reference to the application modalities and improvements adopted by Eni on the matter, the Board of Statutory Auditors feels that the limit of 30% established by the Board for additional remuneration that could compromise independence (see application modality for Recommendation 7, letter d) does not include any remuneration received by the Statutory Auditors for positions held on the control bodies of subsidiaries of Eni, taking due account of the 1997 Consob recommendation on the "group statutory auditor". In any case, the appointment of statutory auditors in group companies takes place in compliance with the provisions and limits on the maximum number of offices provided for by the internal regulations governing the composition of the control bodies of subsidiaries. Furthermore, the aforementioned limit does not include the remuneration received by the Statutory Auditor for serving as members of the 231 Supervisory Body of Eni SpA. This application modality is highlighted in the text of the Corporate Governance Code published on the Company's website.

Most recently on February 21, 2023, the Board of Statutory Auditors confirmed that the independence and integrity requirements continued to be satisfied, as demanded of all its members. At its meeting of February 22, 2023, the Board of Directors made its own verification.

On May 14, 2020, after the appointment, and lastly on February 21, 2023, the Board of Statutory Auditors, in its role as "Internal Control and Financial Auditing Committee", also evaluated its satisfaction of the requirements imposed by the provisions of Art. 19 of Legislative Decree No. 39/2010, as amended by Legislative Decree No. 135/2016 providing that "the members of the internal control and financial auditing committee, as a body, are competent in the sector in which the company being audited operates" and verified compliance with the requirements for members of the Board of Statutory Auditors in their capacity as "Audit Committee financial experts", for the purpose of US law.

Pursuant to applicable regulations, persons may not hold office in a control body of an issuer if they hold the same office in five other listed companies.

As long as they hold office in the control body of just one issuer, persons may hold other management and control positions in Italian companies, within the limits specified in the Consob regulations.

The Statutory Auditors are required to report the offices they hold or have relinquished, in the manner and within the time limits established in the applicable regulations, to Consob, which shall then publish the information, making it available on its website.

3.8.4 MEETINGS AND RUNNING OF MEETINGS

The Statutory Auditors, simultaneously with the Directors, receive documentation of the issues on the agenda to be discussed at the Board of Directors meetings, and according to the By-laws the Board of Directors and CEO shall report, on at least a quarterly basis or, in any case, during the Board of Directors meetings on the activities performed and on transactions with the greatest impact on the performance and financial position carried out by the Company and its subsidiaries, in addition to providing a comprehensive bimonthly and semiannual statement on transactions carried out with related parties and in particular on transactions in which Directors or Statutory Auditors have an interest, in compliance with the corporate procedure governing transactions with related parties146.

Under that procedure and in compliance with the provisions of Recommendation 37 of the Corporate Governance Code, the Statutory Auditors must inform the Chairman of Board of Directors and the other Statutory Auditors of any personal or third-party interests they hold in relation to any given transaction of the Company.

The Rules of the Board of Auditors, in its capacity as the Audit Committee for the purposes of the Sarbanes-Oxley Act, are published on the website of the Company.

The Board of Statutory Auditors may also meet via videoconferencing or teleconferencing systems.

The Board of Statutory Auditors in office met 20 times in 2022.

The average duration of the meetings was 3 hours and 37 minutes. In 2022: (i) on average 98% of the Statutory Auditors attended the meetings of the Board of Statutory Auditors; (ii) 99% of the Statutory Auditors attended the meetings of the Board of Directors.

Moreover, in 2022 the Chairman of the Board or a Statutory Auditor designated by her, or with regard to certain issues, the entire Board of Statutory Auditors attended all of the Control and Risk Committee meetings and the meetings of the other Committees of the Board of Directors147.

In 2023, as of March 16, 2023, the Board held 6 meetings. A further 13 meetings are scheduled before the end of the year.

In 2022, the Board of Statutory Auditors participated in specific induction and training initiatives started in 2020 after the appointment and carried out for the Statutory Auditors, the Directors and other Board Committees.

3.8.5 REVIEW AND GUIDELINES FOR SHAREHOLDERS ON THE COMPOSITION OF THE BOARD OF STATUTORY AUDITORS

REVIEW FOR 2022

Board of Statutory Auditors Review

Guidelines for shareholders

As was the case in the previous years, complying the provisions of the Rules of Conduct of the Board of Statutory Auditors issued by the National Council of Chartered Accountants and Accounting Experts and in line with the Recommendations of the Corporate Governance Code, the Board of Statutory Auditors performed an assessment of its own composition and operation.

This process, carried out with the support of an external consultant (Crisci & Partners) in order to strengthen its objectivity, showed the overall effectiveness and efficiency of the Board's action, now in its third year in office. The process also confirmed the overall adequacy of the composition of the Board of Statutory Auditors, in terms of diversified experience, skills and knowledge. It also confirmed the commitment of the Board of Statutory Auditors to engage in a constant interaction with the Board of Directors and the Board Committees as well as the Boards of Statutory Auditors of subsidiaries. Activities carried out in its role as Internal Control and Financial Auditing Committee were also reviewed and positively assessed within the selfassessment exercise.

GUIDELINES FOR SHAREHOLDERS ON THE COMPOSITION OF THE BOARD OF STATUTORY AUDITORS

See below for the guidelines published on the Company's website on March 6, 2023.

The next Shareholders' Meeting, convened for 10 May 2023, will appoint the new Board of Statutory Auditors. Therefore, the latter, having reached the end of its term and drawing on its experience and the results of a self-assessment148, provides the Shareholders guidelines on how to determine the best candidates to propose to the Shareholders' Meeting for the quantitative and qualitative composition of the Board of Statutory Auditors.

¹⁴⁷ In 2022, the Statutory Auditors Giovanna Ceribelli and Marco Seracini also conducted three and four individual controls respectively in the course of examining the quarterly reports prepared in accordance with internal Rules governing the process of receiving analysis and handling whistleblowing reports sent or transmitted to Eni, including confidentially or anonymously, concerning problems relating to internal control and risk management, financial reporting, the Company's administrative liability, fraud and other matters (whistleblowing). The Statutory Auditor Giovanna Ceribelli completed the individual investigation activity, started in December 2020 with the then Standing Statutory Auditor Roberto Maglio (which he continued until the end of his mandate with the Shareholders' Meeting of 12 May 2021), on the procurement process and the anti-corruption compliance model in order to report to the Board of Statutory Auditors.

¹⁴⁸ In addition to the Rules of Conduct for the Board of Statutory Auditors, for the purposes of this document, it is considered that the recommendations addressed to the outgoing Board of Directors by the Corporate Governance Code may also be analogously applicable in the event of a renewal of the Board of Statutory Auditors (see, in particular, Articles 2 "Composition of Corporate Bodies" and 4 "Appointment of Directors and Self-Assessment of the Board of Directors").

Context

The guidelines offered by the outgoing Board come at the end of a term marked by numerous factors of significant strategic and transformative significance, as well as the impacts of the pandemic crisis and recent geopolitical and economic events, which have further impacted control activities. The strategy of enhancing and evolving Eni's businesses, also through controlled corporate vehicles, the so-called 'satellite model', represents a distinctive element to be considered in relation to the supervisory activities of the Parent Company's Board of Statutory Auditors.

It should also be emphasised that, since Eni is listed on the New York Stock Exchange, the Board of Statutory Auditors also performs the role and duties of an Audit Committee pursuant to SEC rules and the Sarbanes-Oxley Act, i.e. it carries out functions additional to those envisaged by applicable legislation for issuers listed on the Italian market.

Finally, the responsibilities required of the auditing body have been and will be further expanded in terms of information flows and monitoring activities, in light of the entry into force of European-level implementing regulations, both recent and expected in the next three years (concerning, inter alia, statutory audit regulations and non-financial reporting).

Size, Requirements, Tenure and Diversity

The Company's By-laws provide for the composition of the Board of Statutory Auditors to consist of five statutory auditors and two alternate auditors, and among the requirements of professionalism, gives prevalence to commercial law, business economics and corporate finance.

The Board draws the shareholders' attention to the need to ensure the regulatory requirement that competence in the field in which the company operates must be held by the Board as a whole.

The Board recognises the value of diversity in its composition, not only with regard to gender, while respecting the primary objective of ensuring adequate competence and professionalism for its members.

Availability of Time

For an effective interpretation of one's role, it is of paramount importance that candidates offer complete evidence they can guarantee the necessary time to prepare for and participate in the demanding activities of the assignment149.

To this commitment must also be added, for the Chairman of the Board of Statutory Auditors, the time devoted to carrying out the role and the activities of preparing, organising and coordinating the activities and meetings of the Board.

Experience, Skills

On the basis of the experience gained and the activities and challenges that the new body will have to face, the Board of Statutory Auditors considers it indispensable that the selected professionals have - on the whole - adequate experience in large and international listed companies in various industrial sectors, with highly structured and complex governance.

The Board has also identified an additional requirement for its efficient and effective functioning, namely the ability to work in a team and manage complexities in a constructive and balanced way. Decisive in this regard is the role of the Chairman, whose authority is essential both for creating cohesion and collaboration between Board members, and in the interaction with other

¹⁴⁹ In terms of meetings, in 2022: Board of Statutory Auditors (20 meetings, with an average duration of almost 4 hours); Board of Directors (16 meetings); Internal Board of Directors Committees (a total of 44 meetings, all attended by at least one Statutory Auditor); On-boarding/induction sessions; Coordination meetings relative to the entire Group.

corporate bodies, structures and people in general and, more specifically, with those responsible for the internal control and risk management system.

Lastly, the Board offers guidelines on how to assess, within the framework of the main contributions of skills, experience and knowledge, including "soft" skills, the following aspects that it believes support and appropriately complement the qualitative composition of the Board:

− expertise in financial and non-financial reporting;
− risk management, governance and compliance skills with reference to complex corporate groups;
− skills and/or experience in climate change/energy transition;
− experience in extraordinary finance and M&A transactions;
− collaboration, influence and resolution of potential conflicts;
− assertiveness, dialogue skills, authenticity, standing-up and communication skills.

Remuneration

The Board of Statutory Auditors deems it appropriate to mention the Corporate Governance Code150, which states that, in order to attract persons of adequate "standing", remuneration of the members of the control body must provide for an amount appropriate to the competence, professionalism and commitment required by the relevance of the role covered and by the company's size and sector characteristics, and be determined taking into account the remuneration practices widespread in the reference sectors and for companies of similar size, also considering comparable foreign realities and practices.

In order to assess the adequacy and fairness of the remuneration attributed by the Shareholders' Meeting to the members of the Board of Statutory Auditors, a useful indication is comparison with the remuneration paid to non-executive Directors, considered inclusive of remuneration for participation on Internal Board of Directors Committees, also for the purpose of consistent treatment of the corporate bodies.

3.9 Internal Control and Risk Management System151

Focus on compliance

In order to promote and maintain an adequate Internal Control and Risk Management System (ICRMS), Eni utilises organisational, informational and regulatory tools, aimed at making it possible to identify, measure, manage and monitor the main risks that Eni faces and, in line with the 2020 Corporate Governance Code adopted by Eni, contribute to the sustainable success of the Company.

This system is integrated into the organisational, administrative and accounting structure and, more generally, into Eni's Corporate Governance framework, and is based upon corporate governance recommendations, taking into consideration national and international reference models and best practices, aimed at strengthening their overall effectiveness and efficiency, taking account of the international nature of the Company.

In this respect, the CoSO Report represents the internationally recognized reference framework for the understanding, analysis and integrated evaluation of the effectiveness of the ICRMS. Further reference models are reported in the following paragraphs.

Particular attention is paid to compliance, which Eni considers a key factor in protecting the Company from risks, safeguarding its assets and contributing to the effectiveness and efficiency of all business activities. To this end, Eni's rules on the individual areas of compliance are conceived from a "risk driven" perspective and filtered through international best practices. On December 23, 2020, Eni's Board of Directors resolved to adopt the 2020

¹⁵¹This chapter is approved by the Board of Directors, with the support of the Control and Risk Committee; the audit firm expresses an opinion on the consistency of specific information contained in the Corporate Governance Report pursuant to Art. 123-bis, fourth paragraph of the Consolidated Law on Financial Intermediation, with the consolidated financial statements of the Eni group and on their compliance with the law.

Corporate Governance Code, the Recommendations of which are applicable from January 1, 2021. In its meeting of January 21, 2021, the Board approved some adjustments and application procedures, including improvements, in compliance with Art. 6 of the Code, relating to the ICRMS.

ICRMS GENERAL GUIDELINES AND RULES OF IMPLEMENTATION

The ICRMS General Guidelines approved by the Board

The General Guidelines set forth the primary roles and responsibilities relating to the ICRMS, setting out the principles governing the coordination 152 and the exchange of information between the various actors involved in the ICRMS, pointing out models and national and international best practices, in order to maximise the efficiency of the system, reduce any duplication and ensure effective performance of the duties of the supervisory body153.

The General Guidelines were most recently modified on October 25, 2018 154 to reflect the changes in roles, responsibilities and information flows according to the new Integrated Compliance process and are expected to be updated during 2023, in line with the new Eni Regulatory System155.

provide all Eni management with a suitable framework for implementing this system;
ensure that the Board receives every six months for the ICRMS and every three months156 for risks, a comprehensive representation of the various elements of the system on which to base its decisions.

Starting from January 1, 2021, the roles, responsibilities and regulatory instruments relating to the ICRMS, pending their formal update, take into account the new Recommendations of the Code, as well as the decisions taken by the Board of Directors regarding the application procedures of the same Recommendations. In particular, when applying the Principles and Recommendations of the Code on the ICRMS, in addition to identifying the adjustment measures of the corporate regulatory instruments on the subject, the Board:

• confirmed that the assessment of the adequacy and effectiveness of the ICRMS must take place every six months (an improvement over Principle XIX of the Code);

established that the Board, upon the proposal of the CEO and with the support of the Control and Risk Committee, should define the specific annual guidelines of the ICRMS in the context of the Four-Year Plan157 and assess their implementation annually, based on a report from the CEO, without prejudice to the ICRMS guidelines (the "ICRMS model") outlined in internal regulations (an improvement over Principle XIX of the Code);
provided that the Board, upon the proposal of the CEO, having heard the Control and Risk Committee and the Board of Statutory Auditors, should outline the principles ruling the coordination and information flows between the various subjects involved in the ICRMS (application modality referred to Principle XX and Recommendation 37 of the new Code).

Most recently, on March 16, 2023, the Board of Directors, having considered all the Reports on record at the meeting (i.e. the Report of the Financial Reporting Officer, the 2022 HSE Report with 2023 plan, the Integrated Compliance Report, the Reports of the Control and Risk Committee, the Report on Risks and the Report on compliance with financial risk Limits, as well as the Report on the organisational structure), with the opinion of the Control and Risk Committee, evaluated as positive: (i) the adequacy and effectiveness of the ICRMS and its organisational structure with respect to the characteristics of the company and the risk profile assumed (ii) the adequacy of the powers and resources available to the Financial Reporting Officer and the effective compliance with the administrative and accounting procedures prepared by the same.

On July 28, 2016, the Eni Board of Directors approved a number of changes to the Company's organisational macro-structure in the area of the ICRMS, forming the Integrated Compliance function, which reports directly to Eni's CEO, effective since September 12, 2016.

The Head of the Integrated Compliance function, who reports directly to the CEO of Eni SpA177, is appointed by the CEO having heard the Chairman of the Board of Directors.

The Integrated Compliance function (hereinafter "COMP") is responsible for overseeing legal compliance issues (including, for example, corporate administrative liability, the Code of Ethics, anti-bribery practices, antitrust, privacy, data protection, consumer protection, market conduct, financial regulation and financial penalties) as well as supervising the model for integrated compliance designed to strengthen a culture and the effective pursuit of compliance in Eni, exploiting the operational synergies in the processes and controls provided for in the various models. Furthermore, for the compliance issues for which there are mechanisms external to COMP, this function, following discussion with the individual heads of the compliance area, establishes appropriate flows of information or coordination mechanisms.

In particular, in 2022 the main areas involved the new MSG "Compliance Models on Corporate Administrative Liability of Eni Subsidiaries" and related Annex "Operational Tools for the Definition and Implementation of the Compliance Models", as well as the new MSG "Antitrust" and related Annex "Activities at Antitrust Risk", the amendments to which strengthened, with a view to integrated compliance, Eni's internal control system and the various compliance programs that make it up.

In 2022 the new version of the special part of Eni's 231 Model was also prepared, "Processes, Sensitive Activities and Specific Control Standards of Model 231" which, in addition to updating and streamlining the Sensitive Activities and the specific control standards, has also been supplemented with the provision of a "by process" approach (as well as by "group of offence") and with a correlation between groups of offences and the Sustainable Development Goals (SDGs) promoted by the UN Agenda 2030.

For further information on the regulatory mechanisms with regard to compliance, including the Integrated Compliance process, see the chapter "Eni's Regulatory System" below.

Guidelines for the Eni Regulatory System

On July 28, 2010, the Board of Directors of Eni SpA approved the basic guidelines for the New Eni Regulatory System, with the goal of rationalising, supplementing and simplifying Eni's regulatory system. The basic Guidelines were updated on June 23, 2016 to bring the Regulatory System into line with Eni's new organisational structure, better integrating it with corporate processes and making it easier for the subsidiaries to use.

All of Eni's operational activities can be grouped into a map of processes instrumental to Company activities and integrated with control requirements and principles set out in the compliance and governance models, based upon the By-laws, the Code of Ethics, the 2020 Corporate Governance Code, the Model 231, SOA Principles and the CoSO Report.

The Policies and MSGs have been disseminated to the subsidiaries, including listed subsidiaries, for the subsequent phases for which they are responsible, in particular formal adoption and adjustment of their existing regulatory systems. In 2022, with a view to pursuing continuous improvement and accompany the Company's transition strategy, Eni has launched an initiative to identify, also through the analysis of market best practices, any improvement actions of the current Eni Regulatory System in terms of instruments and relevant management process.
The new Regulatory System • • •	On January 26, 2023 the Board of Directors of Eni SpA updated the fundamental guidelines of the Regulatory System Policy, in line with the operational and governance requirements required by Eni's new business model: Eni's new strategy, based on increasingly greater diversification of activities and company forms managed, indeed required a change in the architecture, tools and rules of the Regulatory System defined in early 2010. Using the solutions identified, the aim was to achieve a Regulatory System that, with a risk based approach and the same effectiveness as the ICRMS, was characterised by: easier to use regulatory instruments; more streamlined decision-making and operational processes; a more active role and greater awareness of Management in identifying risks and the actions to mitigate them. An architecture based on 4 levels was confirmed, with management and coordination tools in relation to subsidiaries and the operational framework. Roles and responsibilities are updated in line with the new architecture and instruments of the Regulatory System.
	3.11.2 MANAGEMENT SYSTEM GUIDELINE "CORPORATE GOVERNANCE FOR ENI COMPANIES"

Governance system and rules for Eni companies

On October 27, 2022 the Board of Directors of Eni SpA, acting upon proposal of the CEO, having first been examined by the Nomination Committee and by the Board of Statutory Auditors, and having received the opinion of the Control and Risk Committee, updated the

¹⁸¹Exceptions are allowed only in exceptional circumstances. There are no exceptions, as a rule, allowed for MSGs in compliance areas. At its meeting of March 15, 2018, the Board of Directors approved, having obtained the favourable opinion of the Control and Risk Committee, an extension of the scope of application of the Eni Regulatory System to also include Italian companies controlled in accordance with the provisions of the Italian Civil Code but which are not classified in the financial statements as subsidiaries, unless that is ruled out by the provisions of By-laws or agreements with third-party shareholders that regard the regulatory system or other specific issues.

Management System Guideline ("MSG") "Corporate Governance for Eni companies" approved on October 26, 2017 to bring it into line with, among other things, the application practices, several indications of the supervisory bodies and several internal regulatory developments, as well as Eni's business need and the current organization of Eni SpA, to simplify and increase the efficiency of certain processes. The review led to the inclusion of a section on the fundamental principles for the exercise by Eni SpA of management and coordination activities. In this regard, when carrying out the management and coordination activity, Eni shall act with respect for the operational autonomy of the individual companies, in particular those listed and those subject to special regulation, the interests of any third-party shareholders, the confidentiality obligations required in protection of the commercial interests of the companies involved and, in the case of foreign companies, the provisions set out in local regulations.

More specifically, the MSG "Corporate Governance for Eni companies":

governs the legal form and management and control system of Eni subsidiaries, including consortia, indicating the size, composition and operating principles for the related corporate bodies, also in relation to the characteristics of the activity carried out;
defines strict requirements to be met by the members, appointed by Eni, of the management and control bodies of all Eni associated companies, in order to be given and maintain such appointment. Requirements are verified or evaluated and monitored, including through the submission of statements by the candidates182, according to principles of traceability and transparency. With regard to the members of the control bodies, in addition to the requirements provided for by the law and the By-laws, the MSG also provides for requirements concerning integrity and independence or the absence of any conflict of interest, thereby borrowing and expanding the provisions and Recommendations of the Corporate Governance Code followed by Eni SpA183;
defines roles and responsibilities in the process of designating the members of the management and control bodies. With regard to the application and the appointment of members of the control bodies, the MSG provides for the creation of an internal database containing the names of potential candidates who meet the requirements, which are verified by the competent corporate units;
in order to ensure appropriate flexibility, the MSG establishes: (i) the general causes for exemption from the MSG (and associated reporting flows), in the case of specific limitations caused by the presence of third-party shareholders, binding agreements, local or sector regulations, operational reasons connected with the system of delegated powers, as well as situations of temporary misalignment when said misalignment is short term and certain to end; (ii) exceptions to the application of the MSG that must be expressly authorised.

The MSG identifies roles and responsibilities of the functions involved in the nomination process, in the process of communicating a general cause for exemption and in the process for authorising exceptions, also taking account of a classification of the companies involved, so as to engage and increase the accountability of Eni management, which has the most direct knowledge of the individual company and has access to the best managerial leverage, increasing the efficiency of the processes in terms of response times, without compromising the controls. The highest decision-making levels are unchanged for the most relevant companies.

3.11.3 MANAGEMENT SYSTEM GUIDELINE "INTERNAL CONTROL AND RISK MANAGEMENT SYSTEM"

Most recently on October 25, 2018, the Board of Directors of Eni SpA, upon the proposal and subject to the prior opinion of the Control and Risk Committee and having heard the Chairman of the Board of Directors on Internal Audit-related matters, approved the "Guidelines for the Internal Control and Risk Management System" (ICRMS), entrusting the CEO with their implementation. Board guidelines

These general guidelines, which are mandatory for the subsidiaries, are designed to ensure that the main risks to which Eni is exposed are correctly identified, measured, managed and monitored and set out reference principles, roles and responsibilities for the key players in the system, as well as the criteria that the CEO must follow in implementing those guidelines.

The Management System Guideline for the Internal Control and Risk Management System (ICRMS MSG) represent the regulatory instrument with which the CEO, on most recently October 26, 2018, implemented the Board guidelines. This rule, incorporating the aforementioned principles (i) consolidates and structures within a single document the various elements of the Eni ICRMS; (ii) defines the model of relations between Eni SpA and the subsidiaries in this area; and (iii) exploits the opportunities for the rationalisation of reporting flows and the integration of controls and monitoring activities. Internal implementation rules

The ICRMS MSG is used alongside the instruments issued on December 18, 2012 and most recently updated on April 9, 2020, with which Eni developed and implemented a model for the integrated management of corporate risks and a model for integrated compliance, issued on October 29, 2018 and most recently updated on June 24, 2020.

Eni's reference framework for implementation and maintenance of an adequate and working ICRMS provides for a structure of three dimensions, as shown in the following diagrams:

Objectives

Scope of application

1) Objectives – The first dimension represents the view of the ICRMS in relation to the objectives and associated risks that the ICRMS is intended to pursue and manage: Strategic, Operational, Compliance and Reporting.

2) Scope of application – The second dimension regards the scope of application on the basis of which the ICRMS is structured:

• the management and coordination exercised by Eni SpA over the subsidiaries;

ENI: PROFILE, STRUCTURE AND VALUES

entity: Eni SpA and the individual subsidiaries, on the basis of their legal and operational independence, establish an appropriate, functional ICRMS under their own responsibility;
processes adopted by Eni, on the basis of which the ICRMS is structured.

3) ICRMS Process – The third dimension represents the ICRMS process and its individual phases:

definition and implementation of the "internal environment";
identification, assessment and treatment of risks;
definition and implementation of control activities;
monitoring;
re-examination and assessment of the entire system;
disclosure and communication.

This ICRMS process is:

continuous, focusing on improving the overall ICRMS, influencing the definition and achievement of corporate objectives;
integrated into corporate operations, as well as organisational and governance arrangements;
interactive, as the individual phases, while organised into a logical sequence, can receive feedback from the development of each of the other phases so that the value generated by the process is not merely the sum of the value generated by the individual phases;

The SCIGR actors act according to a three-level model of control as outlined in the figure below:

The three levels of

control

3) third level of control: provides independent, objective assurance on the appropriateness and effective operation of the first and second control levels and, more generally, on the Eni ICRMS as a whole.

The structure of the first and second control levels is consistent with the size, complexity, specific risk profile and with the regulatory environment in which each company operates.

The third level of control is exercised by the Internal Audit function of Eni SpA, which, on the basis of a centralised model (described in the "Internal Audit" section), performs its controls using a risk-based approach to the overall Eni ICRMS, monitoring Eni SpA and the subsidiaries.

To enable management and the management and control bodies to perform their roles within the ICRMS, specific reporting flows have been established between the control levels and the management and control bodies. The flows are coordinated and appropriate in terms of content and timing.

All flows supporting the assessment of the ICRMS by the Board of Directors are channelled through the Control and Risk Committee of Eni SpA, which carries out an adequate preparatory analysis and reports it directly to the Board in its periodic reports or through the release of specific opinions. These flows are also transmitted to the Board of Statutory Auditors of Eni SpA to enable it to perform its statutory duties in the field of ICRMS. Reporting to the Board

IMPLEMENTATION AT SUBSIDIARIES

It is the responsibility of the Board of Directors or equivalent body of each Eni subsidiary to establish, manage and maintain its own ICRMS.

Eni SpA, as part of its management and coordination of the subsidiaries, issues and disseminates the guidelines, which are mandatory, and associated implementation model, which is contained in the ICRMS MSG, with which the subsidiaries must comply, establishing an adequate process for monitoring its implementation in the manner envisaged in the Eni Regulatory System.

Without prejudice to the principles regarding the Eni ICRMS, the subsidiaries may adopt the most appropriate procedures for implementing the ICRMS in a manner consistent with their size, complexity, specific risk profile and the regulatory environment in which they operate, with the independence that characterises the operation of the subsidiaries and their bodies and functions, including with regard to statutory requirements.

THE ROLE OF THE BOARD OF DIRECTORS OF ENI SPA IN THE SUBSIDIARIES

As envisaged in the ICRMS MSG and consistent with the Recommendations of the 2020 Corporate Governance Code and in accordance with the powers reserved to itself, the Board of Directors of Eni SpA, with the support of the Control and Risk Committee, establishes the ICRMS guidelines for Eni SpA, its major subsidiaries and the Eni Group.

The Board, with the support of Control and Risk Committee, also examines the main risks facing the Company, identified by taking into account the nature of the business of the Company and its subsidiaries, as reported by the CEO on at least a quarterly basis. With the

Spot Audits

support of the Control and Risk Committee, it also evaluates every six months (except in extraordinary circumstances) the adequacy of the Internal Control and Risk Management System of Eni SpA, its major subsidiaries and the Eni Group with regard to the nature of the business, its risk profile and its degree of compatibility with corporate objectives, as well as its effectiveness.

Most recently at its meeting of March 16, 2023, having heard the opinion of the Control and Risk Committee, the Board of Directors assessed the adequacy and effectiveness of the ICRMS and its organisational arrangements in relation to the nature of the Company and its risk profile184.

3.11.4 MANAGEMENT SYSTEM GUIDELINE "INTERNAL AUDIT"

The Management System Guideline "Internal Audit" ("Internal Audit MSG"), prepared by the Head of the Internal Audit function and approved by the Chairman of the Board of Directors, in consultation the CEO and the Control and Risk Committee, was updated on September 30, 2019.

The Internal Audit MSG includes the guidelines for audit activity ("Internal Audit Charter") approved by the Board on September 19, 2019, consistent with the contents of the ICRMS MSG.

The Internal Audit MSG, which is based upon the Internal Audit Charter, seeks to identify and govern the phases and activities of the Internal Audit process, to indicate the roles and duties of the major participants and to establish the rules of behaviour and principles to be observed in performing such activity. Guidelines for the Internal Audit process

More specifically, the MSG regulates:

1) the definition of the Audit Plan, prepared by the Head of the Internal Audit function and approved by the Board185, using a "top-down, risk-based" approach which makes it possible to identify audits to which priority should be given based upon, among other things, the objectives incorporated in the business and functional area programs, as indicated in the Strategic Plan, and the size and coverage of the major business risks connected with it and based upon the results of the integrated risk management process; Definition of the Audit Plan
- 2) the performance of audits, both scheduled and non-scheduled (i.e. spot audits), by carrying out:
  - preliminary activities to define the objectives and the scope of the audit over the areas potentially at highest risk ("risk-based" approach) and the resources deemed necessary and sufficient to achieve the objectives;
  - verification activities, for the purpose of assessing the adequacy and effectiveness of controls on the risks relating to audited processes, to identify any issues and corrective measures for improving the effectiveness and efficiency of the audited processes. Verification activities are carried out, whenever possible, having direct access to information systems and massive analysis of transactions with data analytics tools and specific Key Performance Indicators (KPIs) related to specified business processes as well as through the use of Natural Language Process and Robotic Process Automation tools, in order to make verification activities more efficient and effective;
  - formalisation and communication of the results in order to confirm, with the structures involved in the audits, any issues that emerged, the timing and content of corrective actions to be taken by the structure that was audited. For each audit a

In the event of a spot audit, the rating is assigned based upon the finding of enough factors to support the opinion of the ICRMS; the monitoring of corrective actions crafted on the basis of the audits, which is carried out in different ways based upon the problems encompassed in the rating of the ICRMS audited, such as: monitoring of all actions through a periodic statement by the structure that was audited (so-called "follow-up by documentation"); operational check of the effective implementation of the corrective action through a dedicated follow-up (i.e. "on-site follow-up") for all actions connected with audit reports with more critical summary assessments of the ICRMS and those concerning higher priority issues not included in those above onsite follow up; flows of information on the ICRMS, consisting of the periodic reports prepared by the Internal Audit function in order to provide information on its activities, the results and correlated suggestions, the procedures for managing risks and the relative containment plans. These reports can be classified into three categories based upon their purpose, frequency of preparation and recipient: half-yearly reports on the main results of the activities carried out by the Internal Audit function, submitted simultaneously by the Head of the Internal Audit function to the Chairman of the Board of Directors, the CEO, the Control and Risk Committee and the Board of Statutory Auditors of Eni SpA; the half-yearly reports are also sent to the Supervisory Body of Eni SpA, for matters of its competence; specific reports, usually annual, for the areas most heavily subject to auditing during the reporting period, prepared, with the goal of explaining the primary recurring internal control issues that cut across several areas and/or are of the greatest importance for the specific area, and the recommendations of common,

integrated compliance defined in the ICRMS MSG.

¹⁸⁷ This refers to the Supervisory Bodies of Italian subsidiaries and International Supervisory Bodies of foreign subsidiaries, pursuant to Model 231 of subsidiaries, where required, and the Compliance Models for corporate liability for foreign subsidiaries. For more information, please refer to the section "Model 231" of this Report.

The goals of the Integrated Compliance process

The goal of the Integrated Compliance process is to promote compliance with laws and regulations applicable to Eni using an integrated, risk-based approach and to develop and disseminate a corporate culture founded on ethical values, proper conduct, and respect for laws and regulations, including by way of specific initiatives of training and awareness.

The compliance areas of relevance to Eni are determined based on the nature of the potential risks of non-compliance. This includes issues for which the Company could be held liable for violations of laws or regulations that entail criminal or administrative sanctions or other penalties imposed by the courts or administrative authorities.

More specifically, the integrated compliance process includes compliance risk assessment aimed at assessing the related risk profile, the effectiveness of mitigation activities and the residual risk profile of the relevant compliance areas, in order to recommend a prioritisation of risks and determine potential actions to better mitigate risk and to optimise the risk-based system of controls.

The process also includes control activities aimed at defining (in the MSGs and other regulatory instruments) and implement risk treatment and monitoring actions, with a view to verifying the adequacy and proper functioning of controls for compliance risks.

The activities within the Integrated Compliance process are aimed at ensuring transparency and accountability in the process and uniformity in the adoption of approaches and mechanisms to support these activities.

The process seeks to provide an integrated vision of compliance risks in line with Company operations and to ensure the efficient management of compliance risk in observance of the principle of general compliance with applicable laws and regulations.

The Integrated Compliance function provides adequate information flows and an integrated view of the status of Eni's compliance efforts to management and to the Company's governing bodies in order to enable them to assess the efficacy and continuing adequacy of the system of managing compliance risk, while supporting informed decision making. The reporting of Integrated Compliance function

In particular, an annual Integrated Compliance Report is prepared, which includes an assessment by the Head of Integrated Compliance concerning the adequacy of the Management System Guideline and the compliance areas covered therein.

This Report, including the Anti-Corruption Report, is submitted for information to the Compliance Committee by Head of Integrated Compliance. It is then presented to the Board of Statutory Auditors and, for examination, to the Control and Risk Committee. The CEO submits, for information, this Integrated Compliance Report to Eni's Board of Directors. Finally the Integrated Compliance Report is also communicated by the Head of the Integrated Compliance function to the 231 Supervisory Body of Eni SpA, for the matters of their concern. The Integrated Compliance Report

Every six months, the Integrated Compliance function prepares an update of the Report based on the results of Integrated Compliance process for the reference semester and any relevant events occurring during the period.

This update is sent, for information, to the Compliance Committee and then presented to the 231 Supervisory Body of Eni SpA, the Board of Statutory Auditors and, for examination, to the Control and Risk Committee, in support of the evaluation of the Board of Directors of Eni SpA about the effectiveness and adequacy of Eni's ICRMS.

3.11.6 MANAGEMENT SYSTEM GUIDELINE "INTEGRATED RISK MANAGEMENT"

The Management System Guideline "Integrated Risk Management" regulates the various phases and activities of the Integrated Risk Management (IRM) process, the roles and responsibilities of the main subjects involved. The IRM process, which is based on a structured, systematic approach, is designed to ensure that all main Eni risks, including medium- and long-term risks, are identified, analysed and consolidated order to support the Board of Directors in making sure they are compatible with strategic goals and support the management in the decision-making process, reinforcing awareness of Eni risk profile and related mitigation activities. The process begins with the contribution to the definition of Eni's Four-Year Plan and continues with the support to its implementation, through periodic risk assessment, monitoring and integrated risk reporting cycles, operational risk management and aggregated risk analysis to enhance understanding of the Company's exposure.
This model for the integrated management of corporate risks is included in the ICRMS and is consistent with international principles and best practices188.
The model comprises the following elements: 1) Risk Governance: represents the basic system for the management of the Company's main risks. The model establishes roles and responsibilities for three distinct control levels, consistent with the indications of the ICRMS and defines information flows; 2) Risk strategy and Integrated Risk Management: includes, among other things, periodic risk assessment and monitoring cycles, analysis and management of contractual and industrial risks, integrated analysis of existing risks in the Countries of operation or potential interest (ICR), and support to the decision-making process for the authorization of investment and other main M&A projects; 3) Knowledge, training and communication on risks: includes professional development of Eni personnel operating in risk management with a dedicated knowledge management system. With regard to Risk Governance, the following have been established:
a) the Risk Committee, chaired by the CEO and composed by Eni's top management. It advices the CEO on the main risks to which Eni is exposed. In particular, it examines and expresses opinions, at the request of the latter, concerning the main results of the Integrated Risk Management process. The Risk Committee invites the Chairman of the Board of Directors to attend its meetings; b) the Integrated Risk Management function, which reports directly to the CEO, whose head is appointed by the latter after hearing the Chairman of the Board of Directors. Among other duties, it: • defines tools/methods for the Integrated Risk Management process, including the identification, in cooperation with the business areas and functions of Eni, of proposals for updating the risk management systems; • performs Integrated Risk Management sub-processes (risk strategy and integrated risk management processes); • presents IRM activity results at least quarterly to the Risk Committee and the Control and Risk Committee, as well as, if requested, to the 231 Supervisory Body; • promotes Risk knowledge, training and communication in order to develop and spread a risk management-oriented culture in Eni. The Board of Directors examines the major risks, identified by taking into account the specific activities conducted by the Company and its subsidiaries, reported on by the CEO at least on a quarterly basis.

IRM Process

Specifically, the IRM process includes the following sub-processes:

i. Risk Governance, Methods and Tools: it refers to the definition by the Eni SpA Board of Directors of the nature and level of risk compatible with the strategic objectives, as well as the policy on risk management so that the main risks are correctly identified and appropriately measured, managed and monitored, thus determining the degree of their compatibility with company management consistent with the strategic objectives identified. This sub-process also defines criteria for the analysis, evaluation, measurement and communication of risks;
ii. the purpose of the "Risk Strategy" sub-process is to contribute to the preparation of the Four-Year Plan and the management performance plans by identifying, on the basis of the overall risk management activity, de-risking areas, the analysis of the risk profile underlying the plan and the management actions;
iii. Integrated Risk Management, including:
- "periodic assessment activities" to ensure a systematic, integrated analysis of the risk profile associated with the strategic objectives approved by the Eni Board of Directors by identifying, assessing and prioritising the main business risks monitoring the associated treatment measures and by reporting all activities;
- industrial risk assessment for the economic evaluation of asset exposure to accidents and classification and assessment of the complexity of wells, as well as analysis of emerging risks;
- "contract risk management" to manage contractual risks before and after the award in order to support the decision-making process in procurement and contract management;
- Integrated Country Risk (ICR) activities to define and measure the integrated risk profile of Countries of interest and support the periodic and project assessment activities;
- Integrated Project Management and M&A activities for the integrated risk evaluation of specific initiatives/activities and, if relevant, the consequent impact on the Company's overall risk profile;
iv. Risk knowledge training and communication seeks to promote the professional development of all Eni resources involved in risk management, develop a common language and spread, at all organizational levels, an adequate risk management culture.

3.11.7 MAIN FEATURES OF THE RISK MANAGEMENT AND INTERNAL CONTROL SYSTEMS APPLIED TO THE FINANCIAL REPORTING PROCESS (MSG "ENI'S INTERNAL CONTROL SYSTEM OVER FINANCIAL REPORTING")189

The Internal Control System applied to financial reporting aims to provide reasonable certainty about the reliability190 of financial reporting and of the capability of the financial report drafting process to yield financial reporting that complies with the generally accepted international accounting principles.

Eni's Internal Control System over Financial Reporting

The rules and methods for the design, implementation and maintenance of Eni's Internal Control System applied to financial reporting for external purposes and the assessment of its effectiveness are set out in the Management System Guideline "Eni's Internal Control System over Financial Reporting (hereinafter in this section also "ICFR MSG") most recently approved by the Board of Directors of Eni on October 7, 2021191.

As presented below, the design, implementation and maintenance of the control system over financial reporting are conducted through a structured process that provides for a risk assessment phase, the development of controls for those risks, the assessment of the controls and the reporting process:

The contents of the ICFR MSG were defined in accordance with the provisions of Art. 154-bis of the Consolidated Law on Financial Intermediation and with the US Sarbanes-Oxley Act of 2002 (SOA), to which Eni is subject as an issuer listed on the New York Stock Exchange (NYSE) and were analysed in the light of the framework issued by the Committee of Sponsoring Organisations of the Treadway Commission (CoSO)192, which, while 5 components of the internal control system193, develops 17 principles whose correct implementation is essential to ensure its effectiveness.

Legal framework and CoSO Report

The 17 principles of the CoSO Report regard in particular: (i) structural elements of the Internal Control System established with the ICFR MSG; (ii) control activities contained in other Eni

¹⁸⁹This section is also provided in accordance with Art. 123-bis, paragraph 2, letter b), of the Consolidated Law on Financial Intermediation. 190Reliability (of reporting): reporting that is accurate and complies with generally accepted accounting principles and meets the requirements of applicable law and regulations.

¹⁹¹This regulatory instrument updates and replaces the previous company rule (Management System Guideline) on the subject adopted by the Board of Directors on December 11, 2014.

¹⁹²Published in 1992 by the Committee of Sponsoring Organizations of the Treadway Commission and subsequently updated.

¹⁹³Represented by the Control Environment, Risk Assessment, Control Activities, Information and Communication and Monitoring.

regulatory instruments (such as, for example, Policies, the Compliance and Process MSG, and Procedures) and refer to best practices already adopted by Eni.

The MSG applies to Eni SpA and its direct or indirect subsidiaries, including listed companies, in compliance with international accounting standards, consistent with their materiality to Eni's financial reporting. Applicability to the subsidiaries

All subsidiaries, regardless of their materiality for the purposes of the Eni's Internal Control System over Financial Reporting, adopt the MSG as a reference framework for planning and implementing their own Internal Control System over Financial Reporting, tailoring it to their size and the complexity of the activities carried out.

The Risk Assessment process, which is conducted using a top-down approach, seeks to identify the companies, processes and specific activities that may generate risk of unintentional errors or fraud that may have a significant impact on the financial statements. The Risk Assessment process

In particular:

the companies that fall within the scope of the control system applied to the financial reporting process are identified both on the basis of the contribution of the various entities to certain aggregates of the consolidated financial statements (total assets, total financial debt, net revenues, income before tax), and considering qualitative items such as the existence of processes that contain specific risks that – if they were to materialise – could jeopardise the reliability and accuracy of financial reporting (such as, for example, fraud-related risks194);
for companies falling within the scope of the control system applied to the financial reporting process, relevant processes are subsequently identified, analysing the quantitative factors (processes that contribute to items of the financial statements in amounts exceeding the materiality threshold) and qualitative factors (e.g., the complexity of the accounting treatment of the account; measurement and estimation processes; new or significant changes in business conditions);
the risks associated with relevant processes and activities, i.e. potential events that – if they were to materialise – could jeopardise attainment of the control objectives with regard to financial reporting (e.g., financial statement assertions) are identified;
the identified risks are assessed in terms of their potential impact and probability of occurrence, on the basis of quantitative and qualitative parameters and assuming the absence of a control system (inherent risk). In particular, with reference to fraud risks195 at Eni, a dedicated risk assessment is conducted using a specific methodology for "anti-fraud programs and controls" referred to in the MSG.

A control system has been defined for relevant companies, processes and the associated risks that is based on two fundamental principles, namely: (i) the application of controls at all levels of the organisational structure, in accordance with their operating responsibilities and (ii) the sustainability of controls over time, so as to ensure that their implementation is integrated and compatible with operational requirements. Control system

The structure of the control system applied to the financial reporting process includes controls implemented at the entity level and at the process level:

Controls at entity level

• the controls implemented at the entity level are organised into a checklist, developed in accordance with the model adopted in the CoSO Report, which is based on five components (the control environment, risk assessment, control activities,

¹⁹⁴ The companies considered within the scope of the Internal Control System include companies formed and regulated in accordance with the laws of countries that do not belong to the European Union, to which the provisions of Article 15 of the Consob Markets Regulation apply. 195Fraud: within the control system, any intentional act or omission leading to deceptive disclosures.

information and communication, monitoring). Of particular importance are the controls relating to the specification of the timetable for preparing and disseminating financial results ("semi-annual and annual financial statements circular" and the associated calendars); the existence of appropriate organisational structures and a regulatory framework adequately designed to ensure the achievement of financial reporting objectives (these controls include, for example, the review and updating by specialised Company units of the Group's regulations concerning financial reporting and the Group's chart of accounts); training in accounting standards and the internal control system applied to financial reporting; and, finally, the activities concerning the information system for managing the consolidation process (Mastro); • the controls implemented at the process level are grouped as follows: (i) specific controls intended as a set of manual or automated activities aimed at preventing, identifying or correcting errors or irregularities that occur during the course of operational activities; (ii) and pervasive controls intended as structural elements of the control system applied to financial reporting and aimed at defining a general context that promotes the correct execution and control of operational activities (such as, for example, the segregation of incompatible tasks and "General Computer Controls", which include all controls designed to ensure the correct operation of IT systems). In particular, among the specific controls, the Company procedures identify the so-called "key controls", the absence or non-functioning of which can give rise to the potential risk of errors/fraud that impact the financial statements and that cannot be identified by other controls. Both the controls implemented at the entity level and the controls implemented at the process level are subject to evaluation (monitoring) to verify the effectiveness of their design and actual functioning over time. For this purpose, the following activities have been defined: on-going monitoring activities – carried out by the management responsible for the relevant processes/activities – and separate evaluations – performed by the Internal Audit function, which uses agreed audit procedures on the basis of a plan transmitted by the Financial Reporting Officer (FRO) – aimed at defining the scope and objectives of the interventions through agreed audit procedures. In addition to its independent monitoring activities, the Internal Audit function, on the basis of the annual Audit Plan approved by the Board of Directors and prepared using a "top-down, risk-based" approach, carries out compliance, financial and operational audits. The findings of the independent monitoring conducted by Internal Audit and the periodic reports containing an assessment of the appropriateness of the ICRMS emerging from the audit activities performed are transmitted to the FRO, as well as top management and the control and supervisory bodies for the purpose of conducting the evaluations for which they are responsible. The monitoring activities allow identification of any deficiencies in the control system applied to financial reporting that are subject to evaluation in terms of probability and impact on Eni's financial reporting. On the basis of their importance, they are classified as "deficiency", "material weakness" or "significant deficiency". The results of the monitoring activities are included in a periodic report on the state of the control system applied to financial reporting, and this reporting is conducted using computerised tools that enable the traceability of information on the adequacy of the design and functioning of the controls. On the basis of this reporting activity, the FRO drafts a report on the adequacy and actual implementation of the control system applied to financial reporting. Controls at process level Evaluation of controls (monitoring) Reporting FRO Report

This report – following approval by the CEO – is submitted to the Board of Directors, after review by the Control and Risk Committee, during the approval of the draft annual and semiannual financial statements, in order to ensure the execution of the aforementioned supervisory activities and evaluations regarding the Internal Control System over Financial Reporting. Furthermore, the above-mentioned report is also transmitted to the Board of Statutory Auditors, in its role as the "Audit Committee" pursuant to US law.

For the Board's assessments, on the adequacy and effectiveness of the Internal Control and Risk Management System as well as on the powers and means available to the FRO and compliance with the administrative and accounting procedures prepared by the same, please refer to the first paragraph of the chapter "Internal Control and Risk Management System", in the part relating to the assessments of the Board of Directors. The Board assessment

Finally, the activities of the FRO are supported in Eni by various persons whose duties and responsibilities are defined in the MSG referred to earlier.

In particular, the control activities involve all levels of Eni's organisational structure, from the operational business managers and unit managers to the administrative managers and the CEO. In this organisational context, a particularly important role in the internal control system is carried out by the person who performs line monitoring (the so-called "tester"), who assesses the design and effectiveness of the specific and pervasive controls, providing information for reports on monitoring activities and any deficiencies encountered, in order to ensure the timely identification of any necessary corrective actions. Line monitoring

3.11.8 MODEL 231

In accordance with the Italian regulations concerning the "administrative liability of legal entities deriving from criminal offences" contained in Legislative Decree No. 231 of June 8, 2001 (hence- forth, "Legislative Decree No. 231/2001"), legal entities, including corporations, may be held liable – and consequently fined or subject to prohibitions – in relation to certain crimes committed or attempted in Italy or abroad in the interest or for the benefit of the Company. Companies may nonetheless adopt an appropriate organisational, management and control model (the compliance model or, hereinafter, Model 231) to prevent such offences. Italian Legislative Decree No. 231/2001

The Eni SpA Model 231 establishes the control arrangements (general transparency standards for activities and specific control standards) for the purpose of preventing the offences envisaged under Legislative Decree No. 231/2001, that have been incorporated into the relevant Company procedures. Eni SpA Model 231

The Eni SpA Model 231 is made up of a General Part called "231 Model of Eni SpA" and of a Special Part called "Processes, Sensitive Activities and Specific Control Standards of Model 231", dictating the control measures that must be set out in the organisational and/or regulatory tools of the company.

This last document, in particular, identifies sensitive activities, that is, those corporate activities implying a criminal risk due to the liability of entities, pursuant to Legislative Decree No. 231/2001, and lists the related control standards against the risk. For regulatory information on Legislative Decree No. 231/2001 and on predicate offences, which may, under the conditions provided for in Legislative Decree No. 231/2001 determine the liability of the entity, a specific legislative appendix has been prepared.

Responsibility for updating

The CEO, who is already in charge, of implementing Model 231, is also responsible for updating it. The CEO is supported in performing this duty by the Technical Committee 231196.

The Board of Directors, upon proposal of the CEO, having heard the Control and Risk Committee and the Board of Statutory Auditors, approves any amendments and/or additions regarding Chapters 3, 4, 6, 7 and 8 of the General Part197. Amendments and/or additions regarding definitions and Chapter 1, 2 and 5 of the General Part198, as well as those relating to the Special Part take effect immediately as they are approved by the CEO who submits them, for information, to the Board of Directors199.

On November 18, 2021, the Board of Directors approved a new version of the General Part of the Model 231 in order to (i) rationalize and strengthen the role of the Internal Control System of Eni SpA and the various compliance programs that make it up in the document, with a view to integrated compliance, also in line with recent best practices on the subject200; (ii) adapt the document to changes in Eni's organizational structure.

With regard to the Special Part, on July 4, 2022 the CEO of Eni SpA approved the updated version of the document "Processes, Sensitive Activities and Specific Control Standards of Model 231", which specifies sensitive activities for the purposes of Legislative Decree No. 231/2001 and sets out the associated control measures.

REGULATORY AND ORGANISATIONAL MODELS FOR SUBSIDIARIES

Eni SpA promotes the adoption and effective implementation by all subsidiaries of an appropriate system to prevent the risk of corporate liability arising in connection with criminal offences. According to the provisions of Eni's internal regulatory instruments, in the management of activities at risk in terms of administrative liability of entities, the subsidiaries adopt and implement principles and control measures consistent with the provisions of the 231 Model of Eni SpA, suitably adapted to take into account applicable local legislation, the specific operations of the entity and its organization. In exercising their autonomy, individual subsidiaries are responsible for the adoption and implementation of the respective 231 Models or other compliance models on the administrative liability of entities.

Compliance Models on administrative liability for Eni's subsidiaries

In 2022, the company regulatory system was reorganised in relation to the corporate administrative liability of Eni subsidiaries, in order to pursue benefits in terms of efficacy and efficiency.

In this regard, the streamlining of the regulatory instruments – with the issue of a single MSG on compliance for the Italian and foreign subsidiaries containing the common principles and guidelines of the compliance models, an annex that sets out the operational tools as well as two application procedures – allows for a more homogeneous representation of the Models on the administrative liability of the Italian and foreign subsidiaries and greater flexibility of application and updates for the methods most subject to changes.

In particular, the new MSG sets out the constituent elements of the compliance models, as well as the duties of management of the subsidiaries and requires that the models identify, among other things: (i) the areas of compliance in relation to the categories of criminal

offences envisaged under Legislative Decree No. 231; (ii) the company activities at risk and the control measures, and (iii) the information flows arising in particular from other compliance models with a view to integrated compliance. The MSG also provides for the creation of International Supervisory Bodies (ISBs), in the foreign subsidiaries at high risk (replacing the Compliance Supervisory Bodies) and at medium risk with the task of overseeing the function, compliance and adequacy of the compliance models. At local level, in the foreign subsidiaries at medium and high risk, the Local Compliance Committees (LCCs) are maintained, tasked with forming and verifying the design of the control measures, as well as verifying the adequacy of the compliance models in relation to relevant local legislation. ISBs and LCCs are supported by the Counsel of the Integrated Compliance function. This reorganisation also aimed to strengthen the risk-based approaches in the design of controls, including with reference to the requirements of local legislation, and to develop the integration of the controls carried out in other areas (combined assurance) with the consequent optimisation of the obligations borne by foreign subsidiaries The representatives designated by Eni on the corporate bodies of associates, consortia and joint ventures promote the adoption of systems to prevent the risk of corporate liability arising in connection with criminal offences that are consistent with the measures adopted by the Eni Group companies, within their respective spheres of responsibility. COMMITMENT, AWARENESS, DISSEMINATION OF THE COMPLIANCE CULTURE AND TRAINING The Board of Directors plays a fundamental role with regard to Model 231 issues, since it has reserved to itself the power to approve the General Part of the Model 231 and the abovementioned MSG on the Compliance model concerning corporate liability for Eni's subsidiaries, and to establish and appoint the members of the 231 Supervisory Body of Eni SpA, on whose activities it receives periodic reporting through the CEO. The CEO is responsible for implementing and updating Model 231, in compliance with the powers conferred to him by the Model itself. The Eni 231 Supervisory Body ensures the preservation and facilitates the distribution, also using internal regulatory instruments, to the relevant Company units of information on sensitive activities and control standards approved by the CEO during Model 231 updates. Furthermore, in accordance with provisions of the law, a disciplinary system for punishing any violations of Model 231 and failure to comply with corporate procedures for implementing control system were incorporated into the Model. With reference to training and communication on corporate responsibility, the following initiatives were carried out in 2022: • workshops organised for each compliance area and aimed at employees of Italian companies included a specific content relating to Legislative Decree No. 231/2001, Model 231 of Eni SpA and the Supervisory Body of Eni SpA; • foreign subsidiaries organised general workshops on the compliance model on corporate responsibility for the members of the Local Compliance Committees as well as specialist training on the design of the control measures applicable to corporate processes at risk and aimed at process management; • on March 10, 2022 a classroom seminar was held to explain the new Model 231 of Eni SpA, aimed at 20 employees in the professional areas at most risk of 231 issues. On May 31 and September 19, 2022 the recording of the training event was streamed via Webex to other employees at high risk of 231 issues (around 1,000 Eni Training and communication The role of the 231 Supervisory Body The role of Eni's Board The disciplinary system

around 90% of the Eni population was trained via the new e-learning course "Code of Ethics, Anti-Corruption and Corporate Administrative Liability", aimed at the entire Eni population in Italy and abroad;
the Model 231 was subject to a specific communication campaign, through the publication on the company Intranet of a promotional video, intended to consolidate employees' knowledge of the Model 231 and its importance for Eni.

3.11.9 ANTI-CORRUPTION COMPLIANCE PROGRAM

Rules and controls for preventing corruption

Internal rules and mandatory adoption for

subsidiaries

In accordance with the "zero tolerance" principle expressed in the Code of Ethics, Eni prohibits any conduct that could facilitate or promote corruption and/or money laundering. To this end, Eni has adopted a system of rules, controls and organisational measures aimed at preventing corruption-related crimes and also instrumental to preventing money laundering in the context of the non-financial activities of Eni SpA and its subsidiaries (Anti-Corruption Compliance Program).

The Eni Anti-Corruption Compliance Program, characterised by its dynamism and constant attention to the evolving national and international legislation and best practices201, was developed in accordance with the applicable anti-corruption legislation and with international conventions, including the United Nations Convention Against Corruption, the US Foreign Corrupt Practices Act and the UK Bribery Act.

The primary internal rules are represented by the Anti-Corruption MSG202, most recently updated by the Board of Directors on June 24, 2021 and issued on July 19, 2021, and additional detailed regulatory instruments that constitute the reference framework for identifying risk activities and control instruments that the Company provides personnel to prevent and counteract the risk of corruption and money laundering. Eni's subsidiaries, in Italy and abroad adopt, by resolution of their Board of Directors, both the Anti-Corruption MSG and the other anti-corruption regulatory instruments.

Furthermore, Eni does its utmost to ensure that both the Company and the entities in which Eni has a non-controlling interest comply with the standards laid down in its internal anti-

corruption rules, adopting and maintaining an adequate internal control system suitable for preventing the violation of applicable anti-corruption and anti-money laundering laws and consistent with the laws and regulations governing the business in the country in which the company or entity is established or where its activities are based.

To ensure the effectiveness of the Anti-Corruption Compliance Program, in 2010 Eni established a dedicated organisational unit, with adequate equipment also in terms of authority and independence, within the "Integrated Compliance" function, reporting directly to the CEO. The Anti-Corruption and Anti-Money Laundering Unit

The Anti-Corruption and Anti-Money Laundering Unit, with specific expertise in the field, is responsible, among other things, for supervising the design and implementation of the Anti-Corruption Compliance Program and providing specialised anti-corruption and anti-money laundering assistance in relation to the activities of Eni SpA and its subsidiaries, with particular reference to the assessment of the reliability of counterparties potentially at risk ("anti-corruption due diligence"), the management of any critical issues/red flags that may have emerged and the preparation of the related contractual safeguards. In particular, the Anti-Corruption MSG establishes that the results of the due diligence process, including any observations of the anti-corruption and money laundering unit, shall be brought to the attention of the person or body authorising the related transaction, including the Board of Directors. Anti-corruption due diligence

Furthermore, the Anti-Corruption and Anti-Money Laundering Unit provides information flows to Eni's top management, management and to the Company's control bodies by preparing an annual report and a six-monthly update on the relevant activities in the context of the Anti-Corruption Compliance Program. This report and the six-monthly update form an integral part of the Integrated Compliance Report and follow the related information flows203. Reporting by the Anti-Corruption and Anti-Money Laundering Unit

Training

With reference to the anti-corruption training program for all Eni employees (including parttime employees), both online courses (e-learning) and training events in the classroom (workshops) are provided. The target audience for the training program is also identified on the basis of a methodology of systematic segmentation of Eni employees in accordance with the level of corruption risk to which they are exposed.

In 2022, anti-corruption training delivered via e-learning included the new course "Code of Ethics, Anti-Corruption and Corporate Administrative Liability", aimed at the entire Eni population in Italy and abroad.

As to the subjects of training, the workshops offer a general overview of the anti-corruption laws applicable to Eni, the risks that could derive from their violation by individuals and entities and the Anti-Corruption Compliance Program that Eni has adopted and implemented to deal with these risks, using an interactive and engaging format based on case studies, with multiple choice questions to test the level of understanding of the topics covered.

In addition, in 2022, the Anti-Corruption and Anti-Money Laundering Unit:

• took action on anti-corruption issues, including through the discussion of case studies, in the context of the training course dedicated to the managing directors of

The purpose of these training sessions is to support the development and consolidation of the professional profile of the Eni Managing Director, with a focus on compliance and risk mitigation issues; • continued the anti-corruption training dedicated to Eni's third parties. In particular: (i) in September, held a webinar aimed at several of Eni's high-risk suppliers; (ii) in the period September-December 2022, trained the employees of the joint venture IOC LLP in Kazakhstan using an online course; • updated the specialist e-learning on the Anti-Corruption Compliance Program dedicated to personnel at medium/high risk; • continued its work of providing regular information and updating on anti-corruption issues, through the creation of anti-corruption content with the Compliance Flashes204, periodically addressed by the Integrated Compliance function to the Company's top management. Eni's experience in anti-corruption matters is also gained through continued participation in international events and working groups, which represent, for Eni, an instrument for growth and promotion and diffusion of its values. In this connection, Eni actively participated in the Partnering Against Corruption Initiative (PACI) of the World Economic Forum, O&G ABC Compliance Attorney Group (a discussion group addressing anti-corruption issues in the Oil & Gas industry) and, in 2021 and 2022, in the Integrity & Compliance Task Force of B20 Italy and of B20 Indonesia respectively. With regard to external assessments of Eni's Anti-Corruption Compliance Program: • in 2013, a global assessment was performed by an independent legal expert to assess the effectiveness of the Anti-Corruption Compliance Program, both in terms of the adequacy of its procedural design and the effective application of such design. The assessment found that both the design and application of the Compliance Program were sound overall, in line with the appropriate benchmarks and international best practices; • in January 2017, was the first Italian company to receive the ISO 37001:2016 "Antibribery Management Systems'' certification for its Anti-Corruption Compliance Program. To maintain this certification, Eni is cyclically subjected to surveillance audits (two every three years) and recertification audits (one every three years). These audits have always been completed positively since 2017. Most recently, in December 2022, the recertification audit was completed positively. 3.11.10 ANTITRUST COMPLIANCE PROGRAM In order to ensure compliance with antitrust legislation, as expressly referenced in the Code of Ethics, Eni has adopted specific rules aimed at disseminating awareness of antitrust legislation within Eni and its Italian and foreign subsidiaries and at ensuring adequate oversight in order to prevent any violations. With a view to continuous improvement, these rules have been subsequently updated and transformed, in April 2017, into the Antitrust Compliance Program, as formalised in the Management System Guideline Antitrust (Antitrust MSG) which applies to Eni and its Participation in conferences and working groups MSG Antitrust The global assessment by independent legal expert Certification ISO 37001:2016

subsidiaries, most recently updated in 2022, especially with a view to optimising the controls and greater alignment, even formally, with Guidelines of the Italian Antitrust Authority on antitrust compliance. Eni further undertakes to exert influence over the various enterprises in which the Company does not hold a controlling interest such that they will adopt guidelines similar to those of the Antitrust MSG.

INFORMATION ON THE OWNERSHIP STRUCTURE

In implementation of the Antitrust Compliance Program, a specific Company function is responsible for conducting assessments of how business initiatives comply with antitrust legislation, including identification of related risks and specifying controls to mitigate those risks, as well as for conducting periodic analyses of the adequacy of the Antitrust Compliance Program, taking account of the risks encountered and related guidelines and best practices, also with a view to proposing potential updates, and for overseeing related training programs.

3.11.11 CONSUMER PROTECTION COMPLIANCE PROGRAM

MSG Code of Commercial Practice and Advertising

Eni has adopted a specific MSG entitled "Code of Commercial Practice and Advertising", which was updated in 2017 in response to the gradual establishment of a code of European Consumer Rights and which includes both rules concerning unfair commercial practices towards consumers and small businesses and the rights of consumers in agreements entered into remotely, as well as other applicable regulations (e.g. e-commerce, nondiscrimination, etc.). The MSG will be reviewed in 2023, including through the introduction of a specific focus on environmental communication and on the compliance measures intended to mitigate the risks of "greenwashing" accusations.

A specific corporate function is also responsible for providing specialist support concerning laws and regulations protecting consumers and small businesses, assisting Eni and its subsidiaries in Italy and abroad in adopting marketing and commercial practices and environmental communication in line with best practices and with the principles of professional integrity as well as internal processes that comply with applicable laws and regulations and with guidelines provided by competent local authorities in the matter. This function is also responsible for overseeing related training programs.

3.11.12 PRIVACY AND DATA PROTECTION

Eni has established guiding principles concerning data protection in its Code of Ethics and has long been committed to implementing policies to protect the personal data of its employees, customers, suppliers, shareholders, partners, stakeholders, and all other persons with which the organization comes into contact. To this end, Eni long ago adopted a specific Management System Guideline (MSG), and this MSG has recently been updated to comply with Regulation (EU) No. 2016/679 (i.e. the General Data Protection Regulation, or "GDPR"). In particular, this new Privacy e Data Protection MSG, which was most recently issued on May 12, 2021, takes account of developments in case law and identifies a new organisational model for privacy activities. There MSG represents the heart of the Privacy Compliance Model of Eni and its subsidiaries in Italy and abroad and establishes a system for protecting the rights and personal data of data subjects205.

Eni has appointed a central Data Protection Officer (DPO) for the Group, a position required by law, who is responsible for providing information and advice on data protection issues and for overseeing the application of related laws and regulations. A specific Company function is also responsible for overseeing coordination with the subsidiaries and ensuring the flow of information between the DPO and the Company functions or third parties involved, while also providing specialist support to Eni and its subsidiaries and helping to design initiatives with an impact on privacy and data protection ("privacy by design"), supporting Eni and its subsidiaries in adopting an organisational structure and processes that comply with applicable laws and regulations, including the guidelines and other recommendations of regulatory authorities, and overseeing training programs.

²⁰⁵ For the Privacy and Data Protection Compliance area, the main reference models and best practices are: (i) the guidelines, recommendations, decisions and opinions expressed by the European Data Protection Committee "EDPB") and those of the "Article 29" work group (Art. 29 WP) to the extent such documents have been confirmed by the EDPB, (ii) the provisions, general provisions, guidelines and opinions expressed by national and international Authorities on privacy and data protection (e.g. the Italian Data Protection Authority).

3.11.13 PROCEDURE FOR WHISTLEBLOWING REPORTS RECEIVED, INCLUDING ANONYMOUSLY, BY ENI SPA AND BY ITS SUBSIDIARIES IN ITALY AND ABROAD

Since 2006, Eni has adopted internal rules, aligned with national and international best practices, as well as with the Italian legislation (Law No. 179/2017), governing receipt, analysis and processing of reports (so-called whistleblowing), including those transmitted in confidential or anonymous form by Eni SpA and by its subsidiaries in Italy and abroad. In this regard, dedicated and easily accessible information channels have been set up, available on the Company's website.

These internal rules allow anybody, (Eni employees, as well as any third party), to report facts relating to the ICRMS and concerning behaviours in violation of the Code of Ethics, laws, regulations, provisions of the Authorities, internal regulations, Model 231 or Compliance Models for subsidiaries, that may cause damage or prejudice, even if only in terms of image, to Eni. Whistleblowing reports

This process is managed by the Internal Audit function which ensures that all whistleblowing reports received through dedicated channels are examined. All reports that are detailed and verifiable, based on the evaluation of an internal cross-functional team, are subsequently subject to investigation. The checks are carried out by the Internal Audit itself as quickly as possible while ensuring confidentiality, anonymity and the protection of the whistleblower.

Assessments involving whistleblowing reports are summarised in "whistleblowing files" and are aimed not only at ascertaining the truthfulness or otherwise of the reported facts, but also at formulating any recommendations regarding the adoption of corrective actions to strengthen the ICRMS. At the outcome of the investigations, the reporting files are submitted to the approval of Eni Board of Statutory Auditors206, in its capacity as the Audit Committee under US law and, if relevant, to the examination of the Eni 231 Supervisory Body. Investigation phase
The Internal Audit function also reports on its investigations to the Chairman of the Board of Directors, the CEO, the audit firm and, for whistleblowing reports within their area of responsibility, to the top manager of the relevant functions, the heads and the control and supervisory bodies of each Italian or foreign subsidiaries. Information flows

3.11.14 LITIGATION MANAGEMENT REGULATIONS

The "Litigation Management" regulations ware last updated, recently, on February 10, 2023. They govern the process of the communication and internal dissemination of news concerning, in particular, developments in significant litigation or administrative proceedings207 involving Eni SpA and/or its subsidiaries and requires that a team of Eni top managers ("TeamPEG")208, each in his area of expertise, oversee the coordination of the necessary actions – while observing the legal and operational autonomy of the subsidiaries and their control and supervisory bodies – including for the purposes of a proper exercise of management and coordination functions by Eni SpA, where applicable. Purpose of regulations and TeamPEG

Subsidiaries also promptly notify the team of significant legal events, including anonymous reports, which, regardless of whether action has been brought by law enforcement authorities

²⁰⁶ Eni's Board of Statutory Auditors informs the Control and Risk Committee about the whistleblowing files sent to Consob ex Art. 149, paragraph 3, of the Consolidated Law on Financial Intermediation and about the files admitted as founded reports on facts judged as relevant or at least significant for the purposes of the ICRMS.

²⁰⁷Specifically, notices, news and requests received by Eni SpA and/or its subsidiaries or that, in any case, it is made aware of concerning judicial or administrative proceedings, of particular significance to Eni, during the preliminary or trial stage or in the course of investigation or expressly indicated as possible by the authority that has the power to initiate it once the investigations in course have been completed.

(even if in their preliminary and/or investigation phases), relate to certain legal circumstances indicated in the procedure.

The measures governed by the regulation contribute to the effectiveness of the ICRMS, in part to ensure consistency in the action of Eni SpA and its subsidiaries in response to significant legal events.

3.11.15 MANAGEMENT SYSTEM GUIDELINE "TRANSACTIONS INVOLVING THE INTERESTS OF THE DIRECTORS AND STATUTORY AUDITORS AND TRANSACTIONS WITH RELATED PARTIES"209

On May 27, 2021, the Board of Directors, having received a favourable and unanimous opinion of the Control and Risk Committee, approved lastly a few changes in the Management System Guideline (MSG) "Transactions involving the Interests of Directors and Statutory Auditors and Transactions with Related Parties", first adopted in implementation of Consob regulations on November 18, 2010210. Eni's procedure
The MSG, as most recently amended, has applied since July 1, 2021, as required by the Consob "Related Parties" Regulation. Consob regulation and Eni's choices

Most recently, on January 26, 2023211, the Board of Directors judged as positive the design of the MSG, sharing the opportunity to make several changes with a view to continuous improvement, taking into account the application practice, in the context of the update to the Eni Regulatory System.

The current MSG, while being largely based on the definitions and provisions of the Consob Regulation, extends the rules for transactions carried out directly by Eni to all transactions undertaken by subsidiaries with related parties of Eni SpA, with a view to enhancing safeguards and improving functionality.

In line with the provisions of Consob, the definition of "Related Party", extended and defined in greater detail, and the other definitions functional to the application of the discipline, including that of "transaction" are aligned with the international accounting standards in force (with "moving reference" to the IAS pro tempore in force) and placed within the Annex C to the MSG. Types of transactions

Transactions with related parties are divided into transactions of lesser importance, of greater importance and exempt transactions, with procedural arrangements and transparency requirements that vary based on the type and importance of the transaction.

In general, the independent Directors on the Control and Risk Committee or the Remuneration Committee – in the case of certain remuneration issues – play a central role in all significant transactions with related parties. Specifically, for transactions of lesser importance, the procedures require that the relevant committee express a reasoned, non-binding opinion on the Company's interest in completing the transaction and the economic benefits and substantive fairness of the underlying terms, also providing that this opinion must be attached to the minutes of the meeting. Independent Directors

²⁰⁹The MSG "Transactions involving the Interests of the Directors and Statutory Auditors and Transactions with Related Parties" is available in the Governance section of the Company's website.

²¹⁰The first version of the MSG of November 18, 2010 had repealed and replaced the previous Company rules in this area, which had been approved on February 12, 2009.

²¹¹At its meeting of January 19, 2012, the Board of Directors conducted the first annual review of the MSG, as required by the document itself, in advance of the three-year deadline set by Consob. The Board consequently modified the first version of the MSG procedure in a number of areas with a view to facilitate application of the procedures. The MSG and the subsequent amendments received the unanimous, favourable opinion of the former Internal Control Committee of Eni, composed entirely of independent Directors under the provisions of the then in force Corporate Governance Code and in accordance with the Consob Regulation. At its meetings of January 17, 2013, January 16, 2014, January 20, 2015, January 19, 2016, March 17, 2017, January 18, 2018, January 17, 2019, January 16, 2020, January 21, 2021 and January 20, 2022 the Board of Directors, subject to obtaining a favourable opinion from the Control and Risk Committee, conducted an annual review of the MSG.

In line with the provisions of Consob, the definition of "Director involved in the transaction" is reported providing, as for directors in conflict of interest, the obligation to abstain from discussion and voting, also extended to the decisions of the Control and Risk Committee and the Remuneration Committee.

Exempt transactions comprise low-value transactions, differentiated by type of counterparty212, as well as ordinary transactions carried out under market or standard conditions213, intercompany transactions and those regarding remuneration as specified in the MSG, and certain transactions aimed at all shareholders on equal terms, in accordance with the provisions of the Consob "Related Parties" Regulation. Exempt transactions
For transactions of greater importance, without prejudice to the decision-making powers reserved to Eni Board of Directors, the relevant committee is involved early in the negotiation phase and in the preparatory phase of the transaction by receiving complete and updated information and expresses a binding opinion on the Company's interest in the completion of the transaction and the economic benefits and substantive fairness of the underlying terms. Transactions of greater importance
With regard to the disclosures to be provided to the public, the relevant provisions of the Consob Regulation have been fully incorporated in the MSG. Disclosure to the public
The MSG also sets out the timing, responsibilities and verification tools to be used by Eni employees involved and the reporting requirements that must be complied with for the correct application of the rules. In particular, from a risk-based perspective, a mapping of the activities at risk was introduced, including the relative level of associated risk and the graduation of the mitigation measures. Internal processes
Finally, consistent with the choice made with the previous system, the MSG includes specific rules for transactions in which a Director or a Statutory Auditor holds an interest, whether directly or on behalf of third parties, also detailing cases with particular reference to subsidiaries. More specifically, the MSG contains specific monitoring, evaluation and motivation requirements related to the preliminary phase and to the completion of a transaction with a party of interest to a Director or a Statutory Auditor. Transactions with subjects of interest of Directors and Statutory Auditors
- In this regard, both in the preliminary and approval phase, a detailed and documented examination of the reason for the transaction is required, showing the interest of the Company in its completion and the economic benefits and fairness of the underlying terms. In any case, if the transaction is under the responsibility of the Eni's Board of Directors, a nonbinding opinion from the Control and Risk Committee is required.
In order to ensure prompt and effective verification of the implementation of the MSG, a database had been created, listing related parties and Eni's subjects of interest, together with a search application that the agents of Eni and the subsidiaries responsible for preparing transactions can use in order to determine the nature of the transaction counterparty. Database
Moreover, to ensure an effective system of control over transactions, every two months the CEO must report to the Board of Directors and to the Board of Statutory Auditors on the execution of individual transactions with related parties and subjects of interest of Directors and Statutory Auditors, which are not exempt from the provisions of the MSG, and prepare a Periodic reporting

²¹²On the occasion of the latest revision of the MSG the low-value thresholds were reduced with a view to increasing protection.

²¹³A prior verification by the Control and Risk Committee (or the Remuneration Committee) of the applicability of the cause of exclusion for the most significant transactions deemed to be ordinary or carried out at conditions equivalent to market or standard conditions was introduced. In particular, specific information must be communicated to the Control and Risk Committee (or the Remuneration Committee), including the reasons for which the transaction is deemed to be ordinary and carried out at equivalent to market or standard conditions, providing objective elements of feedback, so that the Committee verifies the correct application of the exclusion conditions. If the Committee ascertains that it is not possible to apply the exclusion, the procedure for Transactions with Related Parties of Greater Importance applies. If, on the other hand, the Committee ascertains the correct application of the cause of exclusion, the Transaction can be submitted to the competent body for approval. Consob must be notified within seven days of approval of the Transaction.

semi-annual aggregate report on all transactions with related parties and parties of interest (exempt and non-exempt) carried out during the reporting period. The MSG also establishes that the semi-annual reporting to the Board of Directors and Board of Statutory Auditors shall be transmitted in advance to the Control and Risk Committee as well.

Finally, it is provided that Control and Risk Committee shall receive immediate information on transactions with Directors of Eni SpA or their related parties, other than remuneration, to which a reason for exclusion applies. This information must be provided after the execution of the transaction, in the first meeting of the Committee.

The Board of Statutory Auditors monitors the compliance of Eni's procedures with the principles set out by Consob concerning related parties214, as well as whether their conformity based upon information received and reports to the Shareholders' Meetings on its activities. Monitoring role of the Board of Statutory

Numerous training and information meetings have been held since 2015, coordinated by Corporate Affairs and Governance function, involving all the functions of Eni and its unlisted subsidiaries most affected by the relevant legislation. These activities were accompanied by a session of training for the Board of Directors and the Board of Statutory Auditors, which reviewed the main aspects of the applicable regulations and the associated responsibilities of the corporate bodies and their members. Training

3.11.16 MANAGEMENT SYSTEM GUIDELINE "MARKET INFORMATION ABUSE (ISSUERS)"

MANAGING OF CORPORATE INFORMATION AND INSIDE INFORMATION IN PARTICULAR

Eni recognises that information is a strategic corporate asset and as such must be managed so as to safeguard the interests of the Company. Moreover, the correct disclosure of information is the basis for the orderly functioning of financial markets and their development, contributes to Company's reputation, and reinforces investor trust in the Company.

On October 25, 2018, as proposed by the CEO and having heard the opinion of the Control and Risk Committee, the Board of Directors approved the MSG "Market Information Abuse (Issuers)" and related Annexes, an update to the previous internal regulation for aspects related mainly to issuers215, to new European and Italian legislation, and to the latest guidance of competent authorities. Internal rules approved by the Board

The MSG governs the proper management and disclosure of Company information, and of inside information in particular, and related principles of conduct and implements the specific obligations and prohibitions established by law in order to provide Eni and all Eni personnel with a clear, unified and comprehensive framework of applicable laws, regulations and other obligations safeguarding both the market and Eni.

Therefore, the MSG is intended to make Eni personnel aware of the value of information and the consequences that may derive from poor management of that information.

In particular, as described in greater detail below, the MSG and the associated annexes lay down principles of conduct for the internal management and external communication of corporate information in general and govern: (i) prohibitions on the insider dealing and the unlawful disclosure of inside information; (ii) the internal management and the external

The rules of conduct established by the MSG and the associated Annexes have been adopted to ensure compliance with the legal, regulatory and self-disciplinary measures governing this field in order to protect shareholders, investors, the market, and Eni, also in order to prevent unlawful conduct that could give rise to liability. Purposes of the regulation

In order to facilitate the application of the rules concerning the identification of Eni Inside Information, a mapping of the Eni Relevant Information is provided, along with supporting examples.

The rules further strengthen measures for preserving the confidentiality of corporate information in general, as required by Recommendation No. 1, letter f) of the Corporate Governance Code216, and inside information in particular, ensuring that information is used by employees and members of the corporate bodies in accordance with the principles of sound management of information within the context of the duties assigned to them in the pursuit of the Company business and in compliance with the principles set out in Eni's Code of Ethics and with corporate security measures. Directors and Statutory Auditors shall ensure the confidentiality of documents and information acquired in the performance of their duties and shall ensure compliance with the MSG.

INTERNAL MANAGEMENT AND EXTERNAL DISCLOSURE OF ENI INSIDE INFORMATION

The provisions of the MSG provide a detailed description of the process of internal management and external disclosure of Eni inside information, which had been implemented since July 2016, when the MAR came into effect while awaiting completion of the legislative framework and related interpretations and the consequent adaptation of the MSG. In particular, the MSG confirms, supplements and reinforces the roles and responsibilities of the functions involved in the process, which has been structured so as to allow for the rapid analysis of information and decisions regarding public disclosures, including any use of procedures for the delay of public disclosure.

More generally, in accordance with Consob recommendations, the MSG governs monitoring of the shift from "potentially inside information" concerning Eni ("Eni Specific Relevant Information" in Consob terms) to "inside information" after a mapping of the "Types of Eni Relevant Information", while identifying related mechanisms to ensure segregation and confidentiality (i.e. the "Relevant Information List" and "Insider List of persons with access to Eni Inside Information"). Monitoring of the shift from "potentially inside information" for Eni to "inside information"

During the year, the competent corporate functions continued their work on awareness and training – within Eni SpA and the subsidiaries, also through dedicated e-learning – with a particular emphasis on the accountability of all Eni personnel concerning conduct to ensure the confidentiality of Company information, and of inside information in particular, and concerning prohibitions (against the abuse of inside information and unlawful disclosure) and related sanctions. All training events took place "remotely". Training

²¹⁶The change will be transposed in Eni's MSG at the first amendment opportunity, upon proposal of the Chairman of the Board of Directors acting in agreement with the CEO.

INSIDER LIST OF PERSONS WITH ACCESS TO INSIDE INFORMATION

In line with the provisions of applicable legislation, the MSG governs the rules for maintaining and updating the Insider List of persons with access to Eni inside information (the "Insider List"). Specifically, in accordance with legislative recommendations, the Insider List has been prepared in digital form, and the information systems used allow for the tracking of those who have access to inside information.

In line with the interpretations of European and Italian supervisory authorities, Eni has also opted to include a "permanent" section, in line with Consob recommendations, that lists the Eni persons regularly involved in the assessment of inside information. In this regard, the MSG expressly states that those who are listed in this permanent section are required to take special precautions, given the nature of the information in their possession.

MARKET DISCLOSURE OF DOCUMENTS AND INSIDE INFORMATION

As specifically concerns disclosure to the public of inside information as soon as possible, the MSG confirms that such public disclosure is to take place by way of price-sensitive press releases.

The MSG states that inside information disclosed by way of price-sensitive press releases: (i) is to be disclosed using procedures that allow for rapid access and thorough, accurate and timely evaluation and that ensure impartiality in access to the information using the mechanisms of dissemination and storage specified by applicable laws and regulations; as such, this dissemination must be done without discrimination, free of charge, and simultaneously to the broadest possible audience; (ii) must not be accompanied by marketing of the Company's business; and (iii) is to be stored on the Eni website for a period of no less than five years.

As such, the MSG confirms the rules that Eni has always followed for the public disclosure of inside information (i.e. transparency, no hidden agenda, materiality, clarity, completeness, traceability, homogeneity of information, equal access to information, symmetry of information, consistency, and timeliness). It also maintains the rules for acquiring news and information from the subsidiaries as necessary in order to provide adequate and timely reporting to the Board of Directors and to the markets regarding events and circumstances that could result in inside information.

MANAGERS' TRANSACTIONS (FORMERLY INTERNAL DEALING)

The MSG governs disclosure obligations concerning transactions in Eni financial instruments by persons who perform administration, control or management functions for Eni SpA ("Relevant Persons") and by persons closely associated with them (i.e., the provisions concerning "Managers' Transactions", formerly known as "Internal Dealing") and the prohibition for Relevant Persons to execute transactions during certain periods of the year (i.e. Blocking Period).

Eni SpA Relevant Persons are the Directors, Statutory Auditors, the Magistrate of the Court of Auditors, Executives who report directly to the CEO and to the Chairman of the Board of Directors, and the members of the Management Committee. The MSG specifies the obligations for the disclosure of transactions allowed by law and conducted by Relevant Persons and persons closely associated with them, as well as Eni's obligations of public disclosure.

Disclosures related to transactions that fall within the scope of application of the provisions for Managers' Transactions are also published on the Eni SpA website in the section of the same name.

Eni SpA Relevant Persons

In line with applicable laws and regulations, the MSG governs Blocking Periods during which Relevant Persons are prohibited from executing transactions in Eni financial instruments, either on their own behalf or for others, either directly or indirectly, for 30 calendar days prior to the announcement of an interim or annual financial report. Blocking Period

In addition to the requirements of applicable law, Eni has extended application of the blocking period to 30 days prior to the publication of quarterly reports.

Relevant Persons are constantly reminded of the calendar of Blocking Periods.

These rules were voluntarily extended by Eni to certain other parties for the significant activities performed in connection with the preparation of financial reports and strategic plans in those periods.

3.11.17 MANAGEMENT SYSTEM GUIDELINE "MARKET CONDUCTS AND FINANCIAL REGULATION"

Target of MSG "Market Conduct and Financial Regulation"

The Management System Guideline "Market Conduct and Financial Regulation" – approved by the Board of Directors – with the aim of comprehensively regulating217 i.e., corporate controls concerning the protection, integrity and transparency of the financial and energy markets in which Eni companies operate, taking account of the interaction among the abundant external regulations protecting the integrity and transparency of these markets.

The MSG and its annexes govern the conduct to be adopted to ensure compliance with the provisions of law and regulations in operating in the financial and energy markets, thus preventing illegal conduct giving rise to liability.

3.11.18 MANAGEMENT SYSTEM GUIDELINE "ECONOMIC AND FINANCIAL SANCTIONS"

The Management System Guideline "Economic and Financial Sanctions" – approved by the Board of Directors – defines a comprehensive body of rules and internal controls aimed at mitigating the risk of non-compliance with the provisions of national and international sanction programs, establishing the roles and responsibilities of the parties involved in activities at risk and in the related mitigation measures.

A specific business unit, established within the Integrated Compliance function, has the task of carrying out preventive assessments on the compliance of specific business operations and initiatives, identifying the related risk factors and any ad hoc mitigation actions. Regular internal training programs are defined in line with the level of risk to which the relevant personnel are exposed.

3.12 Audit Firm218

Engagement and term of office

The statutory auditing of Eni's financial statements is entrusted, pursuant to law, to PricewaterhouseCoopers SpA ("PwC"), whose engagement for the financial years 2019-2027 was approved by the Shareholders' Meeting held on May 10, 2018, acting on a reasoned proposal of the Board of Statutory Auditors.

In addition to the obligations set forth in national audit regulations, Eni's listing on the New York Stock Exchange requires that the audit firm issues a report on the Annual Report on Form 20-F, in compliance with the auditing principles generally accepted in the United States,

²¹⁷ Except as regulated by the Management System Guideline "Abuse of Market Information (Issuers)". Further information can be found in the reference paragraph of this Report.

²¹⁸ The audit firm expresses its opinion on this Report pursuant to Art. 123-bis, paragraph 4, of the Consolidated Law on Financial Intermediation.

as well as an assessment of the effectiveness of the internal control system applied to financial reporting, which governs the preparation of the consolidated financial statements.

For the most part, the financial statements of the subsidiaries are audited by Eni's audit firm.

In carrying out its work, the audit firm has access to the information, data (both documentation and digital information), archives and property of the Company and its subsidiaries.

In its meeting of January 16, 2020, the Board of Statutory Auditors approved the document on the "Managing auditing engagements" setting general principles pertaining to the granting and revocation of the engagement, the independence of the audit firm and causes for incompatibility, reporting responsibilities and obligations of the audit firm, and the regulation of the flow of information to the Company and the SEC.

In order to preserve the independence of the audit firms, a monitoring system for "non-audit" work has been created where, in general, the audit firm and its network are not awarded engagements unrelated to the performance of statutory audit activities, except in rare circumstances pertaining to activities that are not prohibited by Italian legislation or the Sarbanes-Oxley Act.

3.13 Control of the Court of Auditors

The financial management of Eni is subject to the control of the Court of Auditors ("Corte dei Conti") in order to preserve the integrity of the public finances219. This work has been performed by the Magistrate of the Court of Auditors Manuela Arrigucci, on the basis of the resolution approved on December 18-19, 2018 by the President's Council of the Court of Auditors. The Magistrate of the Court of Auditors attends the meetings of the Board of Directors and the Board of Statutory Auditors220.

3.14 Relations with shareholders and the market

In compliance with its Code of Ethics and the Corporate Governance Code, Eni has maintained an open and on-going dialogue with institutional investors, retail shareholders and the market, so as to ensure the dissemination of complete, accurate and timely information on its activities, without prejudice to the need to preserve the confidentiality that certain information may require.

The following section describes the policy adopted by Eni for managing dialogue with investors, as recommended by the Corporate Governance Code.

Disclosures concerning periodic reports, the four-year strategic plan, major events and transactions are disseminated through press releases, meetings and conference calls with institutional investors, financial analysts and the press, and are promptly made available to the general public, including by way of publication on the Company's website.

In particular, presentations by top management to the financial markets concerning the quarterly and annual results and the four-year strategic plan are transmitted live on the Company's website, informing retail shareholders, enabling them to participate in the most significant market events in real time.

Relations with shareholders and the market

The policy for managing dialogue with the generality of shareholders

²¹⁹ Pursuant to Art. 12 of Law No. 259 of March 21, 1958.

²²⁰ The Board of Directors resolved to make a token payment of € 1,000 to the Magistrate of the Court of Auditors for attending meetings, in addition to reimbursement of the costs incurred as a result of his office.

Recordings of these events, press releases and the associated presentations and transcripts are available on the Company's website (since 2016; 2012 for press releases).

In response to the need to extend the dialogue with the market, in particular on the subject of the energy transition, during the traditional Capital Markets Day for the presentation of the 2021 results and the strategy related to the 2022-25 Plan (March 18, 2022), the CEO illustrated the further acceleration of the decarbonisation strategy towards the goal of zero net emissions by 2050, from the perspective of energy security and the creation of long-term value for stakeholders through a distinctive approach based on: proprietary technologies, new business models and alliances with stakeholders. The evolutionary and integrated path of the individual businesses by 2050 was also outlined, with indication of the business objectives and targets to reduce emissions by 2025, 2030, 2035, 2040 and 2050 including for intermediate periods.

Following the Capital Markets Day, meetings were held with institutional investors in the main financial centres with the participation of the CEO and top management. Throughout the entire year, continuous dialogue with the market continued, overseen by the Investor Relations function, including participation in conferences organised by the banks that hedge the security. Furthermore, in 2022 Eni participated in the sixth edition of the Borsa Italiana Sustainability Week (September 2022).

In recent years, Eni also intensified dialogue with proxy advisors and investors on its remuneration policy, also with meetings with the Chairman of the Remuneration Committee. These events are part of the engagement policy issued in March 2022.

Over the last few years, Eni has built a business model that puts sustainability at the core of every business activity, including the financial strategy. The integration established by the Company in 2021 by launching the first Sustainability-Linked Financing Framework at international level in its sector, acted as a reference for the connection of multiple financial instruments to relevant objectives of Eni's decarbonisation strategy, including the sector's first issue (January 2023) of a sustainability-linked format aimed at a retail audience.

The Investors section of Eni's website (www.eni.com) is constantly updated with information on dividends, the share price, the trend of the main stock market indices, including credit ratings and ESG, and documentation on the Debt Capital Market and sustainable finance. Furthermore, in 2022 a specific web site page was created for individual investors, to give them the option to track the share performance and its return, as well as the Company's results and Eni's strategies, following them live.

The website also contains, among other things, documents relating to the Shareholders' Meeting, including the minutes of meetings and to the corporate governance system of Eni. The Shareholders' Meeting documentation is provided free of charge to anyone who may request it, including through the Company's website.

A section of the website is dedicated to Eni's Corporate Governance, and the governance model is illustrated with a summary graphic as well as with additional detailed pages. The website also provides easy access to a considerable amount of other documentation, including this Report, previous reports and the documents referred to in the reports.

Again in 2022, Eni was confirmed at the top of Webranking Europe 500 and Italy rankings, dedicated to digital corporate communication, compiled by Comprend in collaboration with Lundquist, which respectively assess the quality of online corporate communication of the European companies included in the FT Europe 500 index and of Italian companies, standing out for the transparency and completeness of their information. Eni also ranked in the Gold Class in Lundquist's most recent edition of Trust" research, evaluating the ability of companies to convey their brand and their business, to communicate leadership and to build a relationship of trust with interlocutors.

Thanks to a growing commitment to transparency and to the business model built by Eni to create long-term sustainable value, in 2022 Eni confirmed or improved the excellence assessments in the main ESG ratings used by the financial markets: MSCI ESG, Sustainalytics ESG Risk Rating, ISS ESG, Bloomberg New Energy Finance Oil&Gas Transition Score, Moody's ESG Solutions, CDP Climate Change, Transition Pathway Initiative; it was also confirmed for the sixteenth year in a row in the specialised stock exchange index FTSE4Good Developed. Finally, Eni was included in the MIB® ESG index of Borsa Italiana, the new index dedicated to blue chips that excel in ESG performance. With reference to gender equality, Eni was included in the Bloomberg Gender Equality Index 2023 and in the Top 100 of the Gender Equality Ranking of Equileap for the second year in a row.

Please refer to the "Investor" page of the Company's website for timely updates on ESG indices and ratings and to the "Responsible and sustainable approach and dialogue with stakeholders" paragraph of this document for further recognition of Eni's ESG approach.

Specific Eni units handle relations with institutional investors, within the terms indicated in the Policy referred to in the following paragraph.

Relations with the media are managed by the Head of the External Communication function; the relevant information is available on the Eni website in the "Media" section and may also be requested by e-mail at: [email protected].

3.14.1 POLICY FOR MANAGING DIALOGUE WITH INVESTORS

On March 8, 2022, the Board of Directors, upon the proposal of the Chairman, acting in agreement with the Chief Executive Officer, has adopted a policy for managing dialogue with the generality of shareholders, denominated "Policy for managing dialogue with investors". The Policy is published on the company's website. Its content is summarized below.

The Policy governs dialogue with Investors221 mainly in the following areas: strategies, performance in relation to communicated targets, sustainability, internal control and risk management, corporate governance, remuneration policies, guidelines on the composition of the corporate bodies, shareholders' remuneration policies, share performance, significant transactions, transactions with related parties, By-laws, methods of running shareholders' meetings.

Eni ensures a clear, correct, timely and comprehensive communication with Investors, in compliance with the principle of equal information and the legislation applicable to the management and communication of documents and information concerning the Company, with particular reference to inside information and selective disclosure222.

All participants in the engagement process commit to avoiding any conflicts of interest, even potential.

Dialogue can be initiated by Investors or by the Company.

a) Dialogue initiated by Investors

Investors shall direct their dialogue requests to the Investor Relations and Corporate Affairs and Governance functions (the "Contact Functions)223. In particular, Investor Relations is the

²²¹ Shareholders, bondholders, their representatives, asset managers and proxy advisors ("Investors").

²²² In particular, the Company takes into account, among other things, the Q&A published on the Consob website on March 18, 2021 on selective information to shareholders and, in particular, to the controlling shareholder, as well as on the publication of inside information relating to industrial plans.

²²³ The Investor Relations function can be contacted at the addresses available on the Company's website, in the section dedicated to Investors. The Corporate Affairs and Governance function can be contacted at the addresses available on the Company's website, in the section dedicated to Governance.

contact point for all Investors, except retail investors and the controlling shareholder, who should refer to the Corporate Affairs and Governance function.

The Contact Functions shall deal with dialogue requests in the areas of their respective competence and under the direction of the Chief Executive Officer, involving other competent functions as necessary, and provide feedback to investors.

Investors holding alone or jointly normally at least 0.1% of the share capital with voting rights ("Qualified Investors"), may request a dialogue with the Board, the Chief Executive Officer or the Chairman.

Requests for dialogue with the Board on issues that do not fall within the Board's competence or deal with price-sensitive issues shall not be taken into account.

The Chief Executive Officer and/or the Chairman, depending on the recipient of the dialogue request – in consultation with the Directors when requests are directed to the Board – evaluate them224 in order to provide a justified refusal or decide how to manage the dialogue.

If the Qualified Investors request a dialogue with individual Directors vested with particular roles (e.g., the Chairman of a specific Board Committee or all the Directors sitting on a Board Committee), the Chairman and the Chief Executive Officer, having consulted the Directors or the Chairmen of the Committee to whom the request is addressed, decide whether to proceed with the request, providing reasons for any refusal and deciding how to manage the dialogue.

If a Director or a Board Committee directly receives a request for dialogue, they inform the Contact Functions, the Chairman and the Chief Executive Officer, who proceed according to the provisions of the previous paragraph.

Qualified Investors may also ask the Contact Functions for a meeting with the aim to unilaterally present their position to the Directors ("one-way communication"). The Contact Functions evaluate the requests, inform the Chairman, the Chief Executive Officer and the Secretary of the Board and, based on the instructions received, provide feedback to the Qualified Investors, giving reasons for any refusal.

Without prejudice to the provisions of the previous paragraph, if Qualified Investors ask to communicate one-way only with some Directors, and the Chairman and the Chief Executive Officer believe that such communication is of interest to all the Directors, the meeting will be allowed only if it can be attended by all Directors.

b) Dialogue initiated by the Company

Dialogue with Investors can also be initiated by the Company, through the organization of either collective or bilateral meetings.

In particular, periodic opportunities for engagement with institutional investors include:

conference call225 for illustrating economic and financial results of the period previously communicated to the market;
"Capital Markets Day"226 for updating the group's strategic plan;
"roadshow" on specific issues.

²²⁴ In evaluating dialogue requests, the following aspects can be taken into consideration: appropriateness and significance of the issues; degree of knowledge gained by the Investor; potential interest of the topics for a large number of investors or for important investors; effective relevance of dialogue and its foreseeable usefulness, also with a view to long-term value creation; voting policy of the investor in previous shareholders' meetings justifying an in-depth analysis; size and characteristics of the investor, nature and strategy of their investment; commitment, investment and voting policies adopted by the Investor; predictable approach of investors with respect to the matters subject to dialogue; any changes in the composition of the Board of Directors; features of shareholder activism implemented by investors interested in dialogue with the issuer or other issuers.

²²⁵Conference calls are also open to financial analysts.

²²⁶ Capital Markets Days are also open to financial analysts and rating agencies.

The Company may also organise meetings with retail shareholders. The dialogue initiated by the Company takes place in the manner defined by the Chief Executive Officer.

Board Committees can propose to the Chairman and the Chief Executive Officer to organise meetings with Investors on issues within their remit, suggesting the relevant methods. Information to the Board

The Chairman ensures, with the assistance of the Secretary of the Board who periodically acquire any relevant information, that the Board is kept informed on the development and the significant contents of different engagement activities with Investors provided for by this Policy.

Information on engagement activities is provided at the first subsequent meeting227, in case of significant outcomes and in any case every six months, usually in April and October, taking into account evaluations expressed by different categories of investors.

In 2022 and 2023, the Board was kept informed about the most relevant issues subject to dialogue with shareholders, regarding the evaluations expressed by different categories of investors and any initiatives adopted to take into account the indications that arose. In particular, the information concerns the main comments from analysts following the Capital Markets Day held on March 18, 2022, the positive feedback from shareholders to the climate strategy published in view of the 2022 Shareholders' Meeting and the outcome of meetings held with the proxy advisors and institutional investors in relation to remuneration topics. Information to the Board on the relevant issues subject to dialogue

The following tables show the structure and meetings of the Board of Directors, the Committees and the Board of Statutory Auditors.

²²⁷ To this end, the items on the agenda of each board meeting can also be taken into account.
