INNATE PHARMA AT A GLANCE

Innate Pharma SA (the "Company" and, with its subsidiaries, the "Group"), is a biotechnology company focused on the discovery, development and marketing of first-rate therapeutic antibodies intended to exploit the immune system for the treatment of indications in oncology with a significant unmet medical need.

The Company has extensive experience in research and development in immuno-oncology. She was a pioneer in understanding the biology of NK cells (natural killer cells) and subsequently expanded her expertise in the fields of the tumor microenvironment, tumor antigens and antibodies. The Company has built, internally and as part of its development strategy, a broad and diversified portfolio comprising an approved product, three products candidates for clinical treatment and a solid preclinical pipeline. The Company has also established collaborations with leaders in the biopharmaceutical sector, such as AstraZeneca and Sanofi.

Since its creation, the Company has suffered losses due to its research and development ("R&D") activities. The first half of 2020 generated a net loss of 10,334 thousand euros. As of June 30, 2020, shareholders' equity amounted to 207,764 thousand euros. Subject to receiving new milestone payments related to its collaboration agreements, the Company expects to incur additional losses until, if necessary, it can generate significant revenues from its product candidates in development.

The future business of the Company is highly dependent on a combination of factors, including: (i) the success of its research and development activities; (ii) regulatory approval and market acceptance of the Company's future product candidates; (iii) timely and successful completion of the additional funding; and (iv) the development of competitive therapies by other biotechnology and pharmaceutical companies. As a result, the Company is, and should continue to be funded in the short and medium term, through collaborative arrangements for the development and commercialization of its drug candidates and through the issuance of new equity instruments.

The activity of the Company is not subject to seasonal effects.

As of June 30, 2020, the Company owned two wholly-owned subsidiaries: Innate Pharma, Inc., based in the United States, and Innate Pharma France SAS, based in France.

Innate Pharma is based in Marseille, France and listed on Euronext in Paris, and had 247 employees as of June 30, 2020.

HALF-YEAR MANAGEMENT REVIEW

The key elements of Innate Pharma's financial results for the first half of 2020 are as follows:

Cash, cash equivalents and financial assets (current and non-current) amounting to €184.6m (million euros) as of June 30, 2020 (€255.9m as of December 31, 2019). At the same date, the financial liabilities amounted to €18.8m, including €16.8m of non-current liabilities (€18.7m as of December 31, 2019, including €16.6m of non-current financial liabilities).

Revenue and other income amounting to €36.7m (€59.2m for the first half of 2019). This amount mainly results from collaboration and licensing revenue (€28.3m) and from research tax credit (€6.7m). Revenue from collaboration and licensing agreements mainly result from the agreements with AstraZeneca/Medimmune.

Operating expenses amounting to €46.0m (€45.9m for the first half of 2019), of which 68.5% are related

Note on change of accounting standards during the period

to research and development. Research and development expenses amount to €31.5m compared to €36.6m for the first half of 2019 and decrease by €5.3m, which mainly results from a fall in expenses relating to Lumoxiti. During the first half of 2019, AstraZeneca invoiced the Company for expenses in relation to the generation of additional data on Lumoxiti for regulatory purposes, including for the regulatory filing in Europe. Selling, general and administrative expenses amounting to €14.5 million (€9.3 million for the first half of 2019), increasing by €5.3 million, mainly resulting from the costs engaged for the commercialization of Lumoxiti and the structuring of our US subsidiary.

A net loss for the first half of 2020 amounting to €10.3m compared to net income of €13.2m for the first half of 2019.

Those amended standards have no impact on the interim condensed consolidated financial statements.

Application of the following amended standard is mandatory for the first time for the financial period beginning on June 1, 2020:

Covid-19-Related Rent Concessions Amendment to IFRS 16

The Company has not early adopted this amendment.

A. Revenue and other income

Revenue and other income resulted from collaboration and licensing agreements and government financing for research expenditure. Revenue and other income decreased by €22.4 million, or 37.9%, to €36.7 million for the six months ended June 30, 2020, as compared to revenue and other income of €59.2 million for the six months ended June 30, 2019.

in thousands of euro	June 30, 2020	June 30, 2019
Revenue from collaboration and licensing agreements	29,841	51,588
Government funding for research expenditures	6,904	7,567
Revenue and other income	36,745	59,155

Revenue from collaboration and licensing agreements

Revenue from collaboration and licensing agreements decreased by €21.7 million, or 42.2%, to €29.8 million for the six months ended June 30, 2020, as compared to revenues from collaboration and licensing agreements of €51.6 million for the six months ended June 30, 2019. These revenues were derived principally under our agreements with AstraZeneca and are set forth in the table below:

in thousands of euro	June 30, 2020	June 30, 2019
Proceeds from collaboration and licensing agreements	28,349	46,770
of which monalizumab agreement	19,636	24,293
of which IPH5201 agreement	8,713	22,478
Invoicing of R&D costs (IPH5201 and avdoralimab agreements)	1,090	4,418
Exchange gains on collaboration agreement	402	400
Revenue from collaboration and licensing agreements	29,841	51,588

Proceeds from collaboration and licensing agreements

Proceeds from collaboration and licensing agreements result from the partial recognition of the proceeds received in the context of the agreements with AstraZeneca for monalizumab and IPH5201 and which are recognized on the basis of the percentage of completion of the works performed by the Company.

For monalizumab, these amounts result from the partial recognition of the \$250 million non-refundable upfront payment received in June 2015 and the \$100 million milestone regarding the exercise of the option received in October 2018.

For IPH5201, revenue related to the partial recognition of the \$50.0 million non-refundable upfront payment received from AstraZeneca in October 2018 and the \$5.0m milestone payment received in March 2020.

The amounts not yet recognized in revenue are classified as deferred revenue.

Proceeds related to monalizumab:

Revenue related to monalizumab decreased by €4.7 million, or 19.2%, to €19.6 million for the six months ended June 30, 2020, as compared to €24.3 million for the six months ended June 30, 2019. This variance mainly results from the decrease of the budget of one of the clinical trials carried out by the Company in the context of the collaboration. This decrease is not material at the global scale of but its impact is entirely recognized on the period.

As of June 30, 2020, the deferred revenue related to monalizumab is €40.0 million (€24.0 million as "Deferred revenue—Current portion" and €16.0 million as "Deferred revenue—Non-current portion").

Proceeds related to IPH5201:

Revenue related to IPH5201 decreased by €13.8 million, or 61.2%, to €8.7 million for the six months ended June 30, 2020, as compared to €22.5 million for the six months ended June 30, 2019.

The collaboration was initially planned to terminate in December 2019. The recognition period of the revenue was therefore planned on a fifteen months period from October 2018. During the fourth quarter of 2019, the involvement of the Company in the collaboration was extended by twelve months. The recognition period of the revenue was extended accordingly for the deferred revenue remaining as of September 30, 2019, resulting in a fall of the portion recognized in revenue over each period.

As of June 30, 2020, the deferred revenue related to monalizumab is €4.7 million, classified as "Deferred revenue—Current portion".

Invoicing of research and development costs:

Pursuant to our agreements with AstraZeneca, clinical costs for the ongoing Phase I trial of avdoralimab are equally shared between Innate Pharma and AstraZeneca and research and development costs related to IPH5201 are fully borne by AstraZeneca, resulting in periodic settlement invoices. These costs are invoiced back on a quarterly basis.

Revenue from invoicing of research and development costs for the six months ended June 30, 2020 is €1.1 million compared to €4.4 million for the six months ended June 30, 2019. The €3.3 million, or 75%, fall between the first half of 2019 and the first half of 2020 mainly results from a €3.0 million decrease of the research and development costs relating to IPH5201 invoiced back to AstraZeneca following the transition of the program at the clinical stage which is carried out by AstraZeneca.

Government financing for research expenditures

Government financing for research expenditures decreased by €0.7 million, or 8.8%, to €6.9 million for the six months ended June 30, 2020 as compared to €7.6 million the six months ended June 30, 2019. This change is primarily a result of a decrease in the research tax credit of €0.8 million, which is mainly due to a fall in amortization of the acquired licenses (monalizumab and

IPH5201) and decrease of the rate applied to the staff costs to determine operating costs (43% instead of 50%). The impact of these elements on the research tax credit amounts to €0.6 and €0.1 million, respectively.

The table below details government funding for research expenditures for the six months ended June 30, 2020 and 2019.

in thousands of euro	June 30, 2020	June 30, 2019
Research tax credits	6,733	7,494
Grants	171	73
Government financing for research expenditures	6,904	7,567

The research tax credit is calculated as 30% of the amount of research and development expenses, net of grants received, eligible for the research tax credit for the six months ended June 30, 2020 and 2019.

B. Operating expenses

The table below presents our operating expenses for the six months periods ended June 30, 2020 and 2019:

Total operating expenses	(45,989)	(45,879)

Research and development expenses (R&D)

Our R&D expenses in the periods presented primarily relate to activities for our clinical programs. Our research and development expenses are broken down as set forth in the table below:

in thousands of euro	June 30, 2020	June 30, 2019
Monalizumab	(2,112)	(2,192)
Lacutamab	(5,003)	(2,918)
Advoralimab	(3,654)	(2,805)
Lumoxiti(1)	(1,797)	(6,456)

Personnel and other expenses	(15,60)	(15,439)
Total research and development expenses	(31,499)	(36,584)

R&D expenses decreased by €5.1 million, or 13.9%, to €31.5 million for the six months ended June 30, 2020, as compared to R&D of €36.6 million for the six months ended June 30, 2019.

R&D expenses represented a total of 68.5% and 79.7% of the total operating expenses for the six months ended June 30, 2020 and 2019, respectively. As of June 30, 2020, we had 164 employees in research and development functions, compared to 157 employees as of June 30, 2019.

Direct R&D expenses decreased by €5.2 million, or 25.0%, to €15.9 million for the six months ended June 30, 2020, as compared to an amount of €21.1 million for the six months ended June 30, 2019. This decrease is mainly explained by (i) the fall in expenses relating to Lumoxiti, resulting from the performance in 2019 of works in relation to the generation of additional data on Lumoxiti for regulatory purposes, including for the regulatory filing in Europe (ii) a decrease in the costs relating to the preclinical programs (iii) partly offset by a rise in expenses relating to the lacutamab program of which the clinical program Tellomak started in June 2019.

Personnel and other expenses allocated to R&D increased by €0.2 million, or 1.0%, to €15.6 million for the six months ended June 30, 2020, as compared to an amount of €15.4 million for the six months ended June 30, 2019.

Selling, general and administrative expenses:

Selling, general and administrative expenses increased by €5.2 million, or 55.9%, to €14.5 million for the six months ended June 30, 2020, as compared to selling, general and administrative expenses of €9.3million for the six months ended June 30, 2019. Selling, general and administrative expenses represented a total of 31.5% and 20.3% of the total operating expenses for the six months ended June 30, 2020 and 2019, respectively. The table below presents our selling, general and administrative expenses by nature for the six months ended June 30, 2020 and 2019:

in thousands of euro	June 30, 2020	June 30, 2019

Personnel expense includes the compensation paid to our employees, and increased by €2.3 million, or 56.6%, to €6.4 million for the six months ended June 30, 2020 as compared to personnel expenses of €4.1 million for the six months ended June 30, 2019. This increase mainly results from the recruitments completed during the second half of 2019 and the first half of 2020 by our US subsidiary, including the staff allocated to the commercialization of Lumoxiti. As of June 30, 2020, we had 74 employees in selling, general and administrative functions, compared to 43 employees as of June 30, 2019. This rise mainly results from the recruitments of our US subsidiary (23 employees as of June 30, 2020 to be compared to 2 employees as of June 30, 2019).

Non-scientific advisory and consulting expenses mostly consist of auditing, accounting, taxation and legal fees as well as consulting fees in relation to business strategy and operations and hiring services. Non-scientific advisory and consulting expenses increased by €1.8 million, or 76.2%, to €4.1 million for the six months ended June 30, 2020 as compared to €2.3 million for the six months ended June 30, 2019, primarily resulting from the expenses related to the commercialization of Lumoxiti and the structuring of our US subsidiary.

The rise in other expenses mainly results from the insurance costs, which increase by €0.8 million following the listing of the Company on the Nasdaq.

Net income (loss) from distribution agreements

We recognized a net profit of €0.9 million from the Lumoxiti distribution agreement in the six months ended June 30, 2020 (to be compared to a net loss of €3.8 million in the six months ended June 30, 2019), which reflected revenue from sales of Lumoxiti in the period, less administrative and selling expenses associated with the sales revenue allocated to us. This €4.7 million rise mainly results from

Financial income (loss), net

We recognized a net financial loss of €2.0 million in the six months ended June 30, 2020 as compared to a net financial income of €3.8 million in the six months ended June 30, 2019. This variance mainly results from the variance in fair value of our financial instruments (net gain of €2.3 million as compared to a net loss of €2.5 million for the six months ended June 30, 2019 and 2020, respectively). This results decrease in the commercial costs invoiced by AstraZeneca, as a result of the transfer of the commercial activities from AstraZeneca to the Company. It also includes a one-time positive true-up relating to the rebates applied to the gross sales generated over the whole period of commercialization.

from the impact of the COVID health crisis on the financial markets.

The table below presents the components of our net financial income (loss) for the six months ended June 30, 2020 and 2019:

Financial expenses	(4,431)	(1,933)
Net financial income (loss)	(1,986)	3,784

For the six months ended June 30, 2020 and 2019, the foreign exchange gains and losses mainly result from the variance of the exchange rate between the Euro and the U.S. dollar on U.S. dollar-denominated cash and cash equivalents and financial assets. Unrealized losses on financial assets relate to unquoted instruments.

C. Balance sheet items

Cash, cash equivalents, short-term investments and noncurrent financial assets amounted to €184.6m as of June 30, 2020, as compared to €255.9m as of December 31, 2019. Net cash as of June 30, 2020 amounted to €145.7m (€216.7m as of December 31, 2019). Net cash is equal to cash, cash equivalents and short-term investments less current financial liabilities.

Since its incorporation in 1999, the Company has been primarily financed by revenue from its collaboration, licensing agreements (€420.5m in total, or \$480.0m), and by issuing new shares (€306.4m in total excluding sharebased payments and the costs the costs associated with capital increases). The Company has also benefited from the research tax credit (CIR) and fundings received from BPI France (ex-Oseo) in repayable advances not bearing interest and PTZI loan. As of June 30, 2020, the outstanding amount of repayable advances and PTZI loan amounts to €0.5m, of which €0.2m classified as current financial liabilities and €0.3m as non-current financial liabilities.

The Company also has bank borrowings of €14.6m as of June 30, 2020 and €3.8m of lease liabilities.

Regarding the CIR, the Company lost the status of SME at the end of the fiscal year 2019. Consequently, it does not benefit anymore from the immediate reimbursement of the CIR, which is now a debt towards the French government that will be settled against the corporate tax due in France for the three following years. The remaining portion of the tax credit not settled following this period will be reimbursed to the Company. Since its incorporation, the Company benefited of the CIR for a cumulative amount of €97.3 million, of which €80.6 million were reimbursed.

The other key balance sheet items as of June 30, 2020 are as follows:

Deferred revenue of €62.1m (including €20,5m booked as 'Deferred revenue – non-current portion') and collaboration liabilities amounting to €12.0m relating to the remainder of the initial payment from AstraZeneca not yet recognized as revenue or not yet refunded;

Receivables from the French government amounting to €23.4m in relation to the research tax credit for 2019 and the six-month period ended June 30, 2020;

Intangible assets for a net book value of €95.2m, mainly corresponding to the rights and licenses relating to the acquisition of the monalizumab, IPH5201, avdoralimab, and Lumoxiti;

This variance is mainly explained by payments of €87.7 million and €21.1 million received in January 2019 from AstraZeneca in relation to monalizumab and IPH5201 agreements, respectively.

Cash flows from / (used in) investing activities:

Our net cash flow used in investing activities for the six months ended June 30, 2020 were €12.8 million and mainly result from (i) a €13.4 million (\$15 million) additional consideration paid to AstraZeneca regarding Lumoxiti following the submission of the BLA to the European Medicine Agency (EMA) in November 2019 (ii) a €2.7 million additional consideration paid to Orega Biotech in April 2020 relating to IPH5201 following the dosing of a first patient in a Phase I clinical trial and (iii) the acquisition of financial

assets for a net amount of €3.0 million. These items are partly offset by the reimbursement by AstraZeneca of the rebate relating to the acquisition of Lumoxiti (€7.0 million, see Note 5).

Our net cash flow used in investing activities for the six months ended June 30, 2019 were €61.8 million and were mainly driven by the acquisition of intangible assets for €64.1 million.

G. Main risks and uncertainties for the remaining six months of the fiscal year

Risk factors identified by the Company are presented in section 3 of the universal registration document ("Document d'Enregistrement Universel") submitted to the French stock-market regulator, the "Autorité des Marchés Financiers", on April 24, 2020 (AMF number D.20-0352). The main risks and uncertainties the Company may face in the six remaining months of the year are the same as the ones presented in the universal registration document available on the internet website of the Company. Not only may these risks and uncertainties occur during the six months remaining in the financial year but also in the years to come. However, during the first half of 2020, the COVID-19 health crisis occurred. The paragraph below presents an update of the risk assessment related to the current health crisis linked to the COVID-19 coronavirus as set forth in the universal registration document filed with the Autorité des Marchés Financiers ("AMF") on April 24, 2020 (AMF number D.20-0352) and in particular an update of the risk factor related to the COVID-19 coronavirus set forth in paragraph 3.8 of the same document.

The unit set up by the Company to monitor the COVID-19 coronavirus current health crisis and the risks and impacts on the Company is maintained and continues to meet regularly. It addresses the situation along the various lines described below. Despite our heightened vigilance, and

given the evolving and unprecedented nature of this situation, even if certain risks are identified, we may not be able to identify and control all risks.

Staff :

Work organisation on our sites has been and is still being adapted to the changing situation, both internationally and locally, and in compliance with the health and safety measures dictated by the governments of the countries where the Company operates. During the lockdown period, the Company's on-site activity was focused on the opportunity to develop our drug candidates in indications related to COVID-19, in order to limit the number of persons on site and thus limit the exposure of personnel. The activities that can be carried out remotely have been maintained in their entirety thanks to the computer equipment that was already available within the Company. At the end of the lockdown period, research and development activities resumed in their entirety on-site within a short period of time. This lockdown episode resulted in a delay of several weeks, which was not significant given the nature of our activities. On the other hand, business travel by our staff was and still is reduced to the strict minimum, which essentially impacts relations with healthcare staff in hospital centers, whether it be for operations related to the conduct of our clinical trials or operations related to the marketing of Lumoxiti, as discussed below.

Clinical Trials :

The impact of the health crisis on the progress of ongoing clinical trials, whether conducted by the Company or by its institutional or industrial partners, remains uncertain for the coming months. Indeed, the situation varies from one country, region or even hospital center to another, in terms of the inclusion of new patients and the quality and completeness of the data from these trials. Although improvements have been observed, such as the resumption of the Phase I clinical trial evaluating IPH5201 by AstraZeneca, the recruitment of new patients is still limited in some of the hospitals participating in our clinical trials.

In addition, the Company has initiated a clinical development program in diseases related to COVID-19. The lack of knowledge of the pathologies related to this virus creates a

H. Related party transactions

Transactions with related parties during the periods under review are disclosed in Note 19 to the interim consolidated financial statements. No material transaction was risk related to the development of new drug candidates that is slightly higher than what the Company is generally aware of. It should be noted that the Company has obtained public funding (BPI - see note 21 to the condensed consolidated financial statements for the six months ended June 30, 2020) for this program under the PSCP-COVID call for projects.

Marketing :

Interactions with healthcare staff are still very constrained in the activities related to the commercialization of Lumoxiti. Also, the indolent and non-lethal nature of Hairy Cell Leukemia may encourage physicians to postpone or cancel treatment of patients. These factors induce a financial risk related to Lumoxiti's sales.

Partnership :

In the context of this health crisis, our partners may have to reorient their strategy or review the development priorities of their portfolio, which could impact our existing agreements and the progress of the relevant research and development programs or prevent us from entering into new agreements.

Supply chain :

Although no impact has been observed to date on the supply chain for key materials, including investigational or marketed drugs, the Company continues to closely monitor the suppliers involved and the situation in the various geographical areas where they operate or to which these materials transit.

Finance :

The occurrence of some or all of the risks listed here, or other risks related to the health crisis that have not yet been identified, could adversely affect the Company's operations, financial condition and prospects. For the first half of 2020, the Company's financial result shows a net financial loss of €2.0 million, compared to a net financial income of €3.8 million for the first half of 2019. This financial net loss is mainly due to the decrease in the fair value of certain of our financial instruments as a result of the impact of the COVID-19 health crisis on the financial markets.

F. Interim Condensed Notes to the Consolidated Financial Statements

1. The Company and key events

1.1. The company

Innate Pharma S.A. (the "Company" and together with its subsidiaries, referred to as the "Group") is a biotechnology company focused on discovering, developing and commercializing first-in-class therapeutic antibodies designed to harness the immune system for the treatment of oncology indications with significant unmet medical need.

The Company has extensive experience in research and development in immuno-oncology, having been pioneers in the understanding of natural killer cell, or NK cell, biology, and later expanding its expertise in the tumor microenvironment, tumor antigens and antibody engineering fields. The Company has built, internally and through its business development strategy, a broad and diversified portfolio including an approved product, three clinical product candidates and a robust preclinical pipeline. The Company has entered into collaborations with leaders in the biopharmaceutical industry, such as AstraZeneca and Sanofi.

From its inception, the Company has incurred losses due to its research and development ("R&D") activity.

The six months ended June 30, 2020 generated a €10,334 thousand net loss. As of June 30, 2020, the shareholders' equity amounted to €207,764 thousand. Subject to potential new milestone payments related to its collaboration agreements, the Company anticipates incurring additional losses until such time, if ever, that it can generate significant revenue from its product candidates in development.

The Company's future operations are highly dependent on a combination of factors, including: (i) the success of its R&D; (ii) regulatory approval and market acceptance of the Company's future product candidates; (iii) the timely and successful completion of additional financing; and (iv) the development of competitive therapies by other biotechnology and pharmaceutical companies. As a result, the Company is and should continue, in the short to midterm, to be financed through partnership agreements for the development and commercialization of its drug candidates and through the issuance of new equity instruments.

The Company's activity is not subject to seasonal fluctuations.

As of June 30, 2020, the Company had two wholly owned subsidiaries: Innate Pharma, Inc., based in the United States, and Innate Pharma France SAS, based in France

1.2. Key events for the six-month period ended June 30, 2020

On November 22, 2019, AstraZeneca submitted to the European Medicines Agency (EMA) the Marketing Authorization Application (MAA) relating to the commercialization of Lumoxiti in Europe. According to the agreement related to Lumoxiti with AstraZeneca, AstraZeneca is entitled to a \$15,000 thousand milestone that was paid by the Company in January 2020. On January 2, 2020, the Company announced that the EMA has accepted the MAA submission for Lumoxiti. The EMA filling acceptance follows the U.S. Food and Drug Administration (FDA) approval of Lumoxiti in September 2018.

On January 10, 2020, the Company signed an amendment to the lease for the "Le Virage" building in order to expand its premises. This amendment also extends the duration of the contractual commitment. The effective date of this addendum is January 15, 2020. Consequently, and following the application of IFRS 16 standard, the impact on the consolidated financial statements are the following: recognition of a new right-of-use asset of €1,151 thousand and a new lease liability of €1,114 thousand.

On March 10, 2020, the Company announced the dosing of the first patient on March 9, 2020 in the IPH5201 Phase I clinical trial. AstraZeneca made a \$5,000 thousand (€4,365 thousand) milestone payment to Innate under the companies' October 2018 multi productoncology development collaboration. Innate made a €2,700 thousand milestone payment to Orega Biotech SAS pursuant to Innate's exclusive licensing agreement.

2. Basis of presentation and statement of compliance

2.1. Basis of preparation

The interim condensed consolidated financial statements as of June 30, 2020 and for the six months ended June 30, 2020 and 2019 and the related notes (together, the "interim condensed consolidated financial statements") have been prepared under the responsibility of the management of the Company in accordance with the underlying assumptions of going concern as the Company's lossmaking situation is explained by the innovative nature of the products developed, therefore involving a multi-year research and development phase.

The interim condensed consolidated financial statements were approved and authorized for issuance by the Executive Board on September 7, 2020. They have been prepared in accordance with IAS 34, 'Interim Financial Reporting' as issued by the International Accounting Standard Board ("IASB").

Due to the listing of ordinary shares of the Company on Euronext Paris and in accordance with the European Union's regulation No. 1606/2002 of July 19, 2002, the interim condensed consolidated financial statements are also prepared in accordance with IFRS, as adopted by the European Union (EU).

For the presented periods, the differences between IFRS as issued by IASB and IFRS adopted by EU had no impact on the interim condensed consolidated financial statements.

2.2. Use of judgments and estimates

The preparation of financial statements in accordance with IFRS requires the Company to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period.

These estimates can be revised where the circumstances on which they are based change. The actual results may therefore differ from the estimates initially formulated. The estimates and judgments which are mainly used by the Company are detailed in note 18.2 in paragraph x) of the appendix to the consolidated financial statements as of December 31, 2019 of the Universal Registration Document published on April 24, 2020. Estimates and judgments The general accounting conventions were applied in accordance with the underlying assumptions, namely (i) going concern, (ii) permanence of accounting methods from one year to the next and (iii) independence of financial years, and in conformity with the general rules for the preparation and presentation of consolidated financial statements in accordance with International Financial Reporting Standards ("IFRS"). The interim condensed consolidated financial statements do not include all disclosures required for annual financial statements and should therefore be read in conjunction with the consolidated financial statements as of and for the year ended December 31, 2019.

The results of the operations for the six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020 or for any other interim period or for any year in the future.

Except for number of shares and per share amounts, all amounts are expressed in thousands of euros, unless stated otherwise. Some amounts may be rounded for the calculation of financial information contained in the interim condensed consolidated financial statements. Accordingly, the totals in some tables may not be the exact sum of the preceding figures.

which impact the condensed consolidated financial statements at June 30, 2020 are: :

• accounting for collaboration and licensing agreements (note 6 and 13);
• measurement of the subcontracting costs relating to the clinical trial (note 14);
• estimation of shared development costs and transition costs under the AstraZeneca monalizumab agreement and the AstraZeneca Lumoxiti in-licensing agreement (note 5 and 13);
• estimate of the recoverable amount of the acquired and under progress licenses (note 6);
• estimate of the useful life of the acquired licenses (note 6).

2.3. Recently issued accounting standards and interpretations

Application of the following amended standards is mandatory for the first time for the financial period beginning on January 1, 2020 and, as such, they have been adopted by the Company:

• Amendments to IFRS 3 "Definition of a business", published on October 22, 2018.
• Amendments to IAS 1 and IAS 8 relating to the definition of materiality, published on October 31, 2018.

Amendments to IAS 39, IFRS 7 and IFRS 9 relating to the interest rate benchmark reform.

Non-current financial assets generally include a guarantee of capital at the maturity date (which is always longer than one year). These instruments are defined by the Company as financial assets at fair value through profit or loss and classified as non-current due to their maturity.

As of June 30, 2020 and December 31, 2019, the amount of cash, cash equivalents and financials assets denominated in US dollars amounted to €50,380 thousand and €97,688 thousand, respectively.

(1) The Research tax credit is recognized as other operating income in the year to which the eligible research expenditure relates. The Company obtained the repayment of the Research tax credit for the tax year 2018 in the amount of €13,503 thousand in July 2019. The CIR for the tax year 2019 amounted to 16,737 thousand. Following the fact that the Company no longer meets the eligibility criteria for the SME status as of December 31, 2019, the CIR for the tax year 2019 will in principle be offset against the French corporate income tax due by the company with respect to the three following years, or refunded if necessary upon expiry of such a period. The Company recorded as of June 30, 2019 an additional Research tax credit for the six months ended June 30, 2020 of €6,710 thousand.

(2) This amount correspond as of December 31, 2019 to a definitive rebate of \$7,580 thousand as of December 31, 2019 (estimate of \$15,000 thousand or €13,100 thousand as of December 31, 2018 and \$12,400 thousand or €10,896 thousand as of June 30, 2019) granted by AstraZeneca in connection with the acquisition of Lumoxiti rights. This amount has been paid in April 2020. This decrease of \$ 7,420 thousand (€6,455 thousand) is based on the final cost figures for the 2019 financial year for Lumoxiti and invoiced by AstraZeneca. The carrying amount of the intangible asset has been adjusted accordingly (see note 6).

The net book value of the receivables is considered to be a reasonable approximation of their estimated fair value. Trade receivables and others have payment terms of less than one year. No valuation allowance was recognized on trade receivables and others as the credit risk of each debtor was considered as not significant.

(1) This amount includes (i) an additional consideration of €7,000 thousand paid to Orega Biotech in June 2019 in relation to the IPH5201 rights, and (ii) the decrease of the estimated rebate granted by AstraZeneca in connection with the acquisition of Lumoxiti rights for an amount of €2,260 thousand (see note 5).

(2) This amount includes the amortization of rights related to the monalizumab (€2,341 thousand), IPH5201 (€2,191 thousands) and Lumoxiti (€1,237 thousand) intangible assets.

• (3) This amount includes (i) an addition consideration of €2,685 thousand paid to Orega Biotech in April 2020 (€2,500 thousand) and June 2020 (€185 thousand) in relation to the IPH5201 rights following the first patient dosed in Phase 1 clinical trial in Mars 2020 and; (ii) an amount of €1,000 thousand to be paid to Novo Nordisk A/S following the launch of the first avdoralimab Phase I clinical trial.
• (4) This amount includes the amortization of rights related to the monalizumab (€1,686 thousand), IPH5201 (€1,818 thousands) and Lumoxiti (€2,041 thousand) intangible assets.

Monalizumab rights under the 2014 monalizumab (NKG2A) Novo Nordisk agreement

Since their acquisition, monalizumab rights are amortized on a straight-line basis over the anticipated residual duration of the Phase II trials. The Company estimated that it would be fully amortized by the end of the first half of 2022, compared to end of 2021 as estimated as of December 31, 2019. This change is mainly explained by the lengthening of the duration of certain clinical trials which took place during the first half of 2020.

The net book values of the monalizumab rights were €6,255 thousand and €7,941 thousand as of June 30, 2020 and December 31, 2019, respectively.

IPH5201 (Anti-CD39) rights acquired from Orega Biotech

This asset is amortized on a straight-line basis since November 1, 2018 (corresponding to the effective beginning date of the collaboration) until the date the Company expects to fulfill its commitment (end of fiscal year 2020).

Lumoxiti rights acquired from AstraZeneca under the 2018 AstraZeneca multi-term agreement

The license is amortized on a straight-line basis until July 31, 2031, which corresponds to the expiration of the current composition of matter patent, not including any additional patent extensions or patents. The net book value of the Lumoxiti rights were €45,236 thousand and €47,276 thousand as of June 30, 2020 and December 31, 2019, respectively.

The Company applied IAS 36-Impairment of assets and assessed whether there was any indication that an asset may be impaired. The Company estimated the recoverable amount of the Lumoxiti intangible asset using a discounting cash flow model which confirmed that this asset was not impaired. The main following assumptions were used to determine the recoverable amount, based on the cashflows determined from the commercialization plan and the budget approved by Management:

A discount rate of 12.3%;

7. Property and equipment

Assumptions related to selling price increase and sales volume based on the potential market and comparable products;

Decrease in sales volume applied to the forecasted revenue once the related rights fall off-patent.

Sensitivity testing regarding these actuarial assumptions and other assumptions such as: discount rate (+/- 1.5 point), selling price (+/- 5%) and decrease in sales volume once the related rights fall off-patent (+/- 5%) were performed. These tests did not reveal any impairment.

During the transition period which will end on September 30, 2020, Lumoxiti products are commercialized in the US by AstraZeneca who is the owner of the regulatory approval. The Company concluded that it did not meet the criteria for being principal under IFRS 15. Consequently, the net result resulting from all Lumoxiti marketing's operations is disclosed in the item line "Net income / (loss) from distribution agreements."

The Company recognized a €896 thousand net gain and a €3,820 thousand net loss for the six months ended June 30, 2020 and 2019, respectively, corresponding to production and marketing costs, net of sales proceeds, as invoiced by AstraZeneca in relation to Lumoxiti distribution agreement for the period.

17. Income tax / (expense)

Due to the Company's early stage of development, it is not probable that future taxable profit will be available against which the unused tax losses can be utilized. As a consequence, deferred tax assets are recognized up to deferred tax liabilities.

STATUTORY AUDITORS' REVIEW REPORT ON THE HALF-YEARLY FINANCIAL INFORMATION

To the Shareholders of INNATE PHARMA,

In compliance with the assignment entrusted to us by your Annual General Meeting and in accordance with the requirements of article L. 451-1-2-III of the French Monetary and Financial Code ("code monétaire et financier"), we hereby report to you on:

• the review of the accompanying condensed half-yearly consolidated financial statements of Innate Pharma, for the period from January 1 to June 30, 2020,
• the verification of the information presented in the half-yearly management report.

These half-year condensed consolidated financial statements were prepared under the responsibility of the Executive Board on September 7, 2020 on the basis of the information available at that date in the evolving context of the crisis related to Covid-19 and of difficulties in assessing its impact and future prospects. Our role is to express a conclusion on these financial statements based on our review.

Conclusion on the financial statements

We conducted our review in accordance with professional standards applicable in France. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with professional standards applicable in France and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Based on our review, nothing has come to our attention that causes us to believe that the accompanying condensed half-yearly consolidated financial statements are not prepared, in all material respects, in accordance with IAS 34, the IFRS standard as adopted by the European Union applicable to interim financial information.

Specific verification

We have also verified the information presented in the half-yearly management report commenting the condensed half-yearly consolidated financial statements subject to our review prepared on September 7, 2020. We have no matters to report as to its fair presentation and consistency with the condensed half-yearly consolidated financial statements.
