INNATE PHARMA AT A GLANCE
As the Group, is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. Leveraging its expertise in antibody-engineering and innovative target identification, Innate Pharma is developing innovative and differentiated next-generation antibody therapeutics.
Innate Pharma is advancing a portfolio of differentiated potential first- and/or best-in-class assets, focused on areas of high unmet medical need. Its proprietary pipeline is centered on antibody-drug conjugates (ADCs), led by IPH4502, a differentiated Nectin-4 ADC in clinical development for solid tumors, and supported by a preclinical portfolio of next-generation ADC candidates. In parallel, Innate is advancing two partnered late-stage assets: lacutamab, developed with Sobi for T-cell lymphomas, and monalizumab, developed with AstraZeneca for non-small cell lung cancer.
Innate Pharma is a trusted partner to biopharmaceutical companies such as Sanofi and AstraZeneca, as well as leading research institutions, to accelerate innovation, research and development for the benefit of patients.
Since its creation, the Company has suffered losses due to its research and development ("R&D") activities. The first half of 2026 generated a net loss of 19,623 thousand euros. As of June 30, 2026, shareholders' equity amounted to 40,508 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 drug 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 drug 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 mid-term, to be financed through partnership agreements for the development and commercialization of its drug candidates and through the issuance of new equity instruments and debt financing.
The activity of the Company is not subject to seasonal effects.
As of June 30, 2026, the Company had one wholly owned subsidiary: Innate Pharma, Inc., incorporated under the laws of Delaware in 2009. This subsidiary is fully consolidated.
Innate Pharma is based in Marseille, France and listed on Euronext in Paris and Nasdaq in the United States, and had 120 full time equivalent employees as of June 30, 2026.

HALF-YEAR MANAGEMENT REVIEW
The key elements of Innate Pharma’s financial results for the first half of 2026 are as follows:
•Cash, cash equivalents and financial assets (current and non-current) amounting to 21.4m (million euros) as of June 30, 2026 (€44.8m as of December 31, 2025). At the same date, the financial liabilities amounted to €20.2m, including €9.4m of non-current liabilities (€22.6m as of December 31, 2025, including €13.8m of non-current financial liabilities).
•Revenue and other income amounting to €5.7m (€4.9m for the first half of 2025). This amount mainly results from collaboration and licensing revenue (€3.1m) and from research tax credit (€2.5m). Revenue from collaboration and licensing agreements mainly result from the agreements with AstraZeneca/Medimmune and Sanofi/Genzyme.
•Operating expenses amounting to €24.7m (€30.3m for the first half of 2025), of which 68.4% are related to research and development.
Research and development expenses amount to €16.9m compared to €20.5m for the first half of 2025 and decrease by €3.6m, mainly explained by direct R&D expenses, which decrease by €1.5 million, remained at €8.2 million. This change is linked to the phasing of our clinical trials: the completion of clinical trials for lacutamab, the discontinuation of preclinical studies, and the initiation of Phase 1 of our antibody-drug conjugate (ADC) program.
General expenses amounting to €7.8 million (compared to €9.8 million in the first half of 2025), a decrease of €2.0 million. This decrease is due to two factors: (i) a decrease in personnel expenses of €1.5 million following the implementation of a restructuring plan, with these expenses amounting to €3.2 million in the first half of 2026, (ii) a decrease in the use of subcontracting and consulting services.
•A net loss for the first half of 2026 amounting to €19.6m (compared to net loss of €21.3m for the first half of 2025).
Note on change of accounting standards during the period

A.Revenue and other income
Revenue and other income resulted from collaboration and licensing agreements and government financing for research expenditure. They increased by €0.8 million, to €5.7 million for the six months ended June 30, 2026, as compared to revenue and other income of €4.9 million for the six months ended June 30, 2025.

Revenue from collaboration and licensing agreements
Revenue from collaboration and licensing agreements increased by €1.4 million, to €3.1 million for the six months ended June 30, 2026, as compared to revenue from collaboration and licensing agreements of €1.7 million for the six months ended June 30, 2025. As a reminder, these revenues mainly resulted from the spreading of proceeds received in connection with the agreements signed with AstraZeneca in April 2015 and October 2018 with Sanofi in 2016 and 2022. These revenues are recognized when the entity's performance obligation is met. They are recognized at a point in time or spread over time according to the percentage of completion of the work that the Company is committed to carry out under these agreements. Revenue from collaboration and licensing agreements are set forth in the table below:

| Invoicing of R&D costs (IPH5201 agreement) | 417 | 916 | ||||||
| Revenue from collaboration and licensing agreements | 3,115 | 1,671 | ||||||
Proceeds from collaboration and licensing agreements
Proceeds related to monalizumab - AstraZeneca:
Since December 31, 2025, the revenue of this agreement has been fully recognized, and accordingly, no “Current contract liabilities” related to these studies remains. Therefore, no revenue is recognized for the six months ended June 30, 2026, as compared to €0.1 million for the six months ended June 30, 2025.
Proceeds related to IPH5201 - AstraZeneca.
Revenue related to IPH5201 for the six months ended June 30, 2026 is $0.0 as well as for the six months ended June 30, 2025. As a reminder, the revenue is related to the milestone payment received from AstraZeneca
Innate Pharma |Half-year financial report June 30, 2026 | 6
following the signature on June 1, 2022 of an amendment to the initial contract signed in October 2018. This amendment sets the terms of the collaboration following AstraZeneca’s decision to advance IPH5201 to a Phase 2 study.
The Company will conduct the study. Both parties will share the external cost related to the study and incurred by the Company and AstraZeneca will provide products necessary to conduct the clinical trial.
Revenue from invoicing of research and development costs for the six months ended June 30, 2026 was 0.4 million compared to 0.9 million for the six months ended June 30, 2025, or a decrease of (0.5) million.
Proceeds related to Sanofi licensing and collaboration agreement (2016) :
Revenue related to the license and collaboration agreement signed with Sanofi in 2016 is nil for the six months ended June 30, 2026, as well as for the six months ended June 30, 2025.
On April 23, 2025, the Company announced that, in alignment with both company's current strategic priorities, Sanofi and Innate agreed to terminate the 2016 Agreement as it relates to SAR’579/IPH6101 (CD123 ANKET®). Innate regained the rights to SAR’579/IPH6101 in July 2025. Data from the Sanofi-led Phase 1/2 study and Phase 2 preliminary dose expansion of the trial have been transferred to Innate.
In a recent corporate update, Sanofi announced deprioritization of SAR’514, a trifunctional anti-BCMA NK-cell engager. Sanofi retains exclusive development and commercialization rights, and the license terms remain unchanged. It has not triggered any milestone payments as of June 30, 2026.
Proceeds related to Sanofi research collaboration and licensing agreement (2022) :
In December 2022, the Company entered into a research collaboration and license agreement with Genzyme Corporation, a wholly owned subsidiary of Sanofi (“Sanofi”), under which the Company granted Sanofi an exclusive license to Innate’s B7-H3 ANKET® program and options for two additional targets.
In March 2023, Innate Pharma received an upfront payment of €25 million under its research, collaboration and license agreement with Sanofi. This amount consisted of €18.5 million relating to the exclusive license to the B7-H3 technology, which was recognized in profit or loss in June 2023; €1.5 million relating to research activities to be performed over a three-year period, recognized as revenue on a straight-line basis through November 2026; and €5 million relating to the two additional license options, recognized as contract liabilities until their expiration or until the options are exercised.
In December 2023, Sanofi exercised one of its license options for an ANKET® program, resulting in the recognition of €2.5 million in revenue and the payment of a €15 million milestone, of which €13.3 million related to the license was recognized immediately in revenue and €1.7 million related to research activities. These research activities were discontinued following the termination of the agreement in October 2024, which led to the full recognition of the €1.7 million in revenue in 2024. As a result, Innate regained the rights to the IPH67 program, while Sanofi retains a right to compensation on any potential future revenues.
On January 24, 2026, following the expiration of the deadline to exercise the license option on an identified target, the revenue of €2.5 million has been fully recognized. Sanofi always has a right on a non-exclusive license option for an additional target, exercisable up to January 24, 2028. This option is not linked with any other revenue.
Government financing for research expenditures
The table below details government financing for research expenditures for the six months ended June 30, 2026 and June 30, 2025.
Innate Pharma |Half-year financial report June 30, 2026 | 7
| in thousands of euro | June 30, 2026 | June 30, 2025 | ||||||
| Research tax credit | 2,548 | 3,189 | ||||||
| Grants | — | — | ||||||
| Government financing for research expenditures | 2,548 | 3,189 | ||||||
Government financing for research expenditures decreased by €0.6 million, or 20.1%, to €2.5 million for the six months ended June 30, 2026 as compared to €3.2 million for the six months ended June 30, 2025.
The decrease of €0.6 million in the research tax credit is mainly due to the reduction in personnel expenses following the restructuring of the organization to concentrate preclinical and clinical research and development efforts on higher value assets.
As a reminder, 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 fiscal year.
B.Operating expenses
The table below presents our operating expenses for the six months periods ended June 30, 2026 and June 30, 2025:
| in thousands of euro | June 30, 2026 | June 30, 2025 | ||||||
| Research and development expenses | (16,877) | (20,520) | ||||||
| General and administrative expenses | (7,797) | (9,767) | ||||||
| Operating expenses | (24,674) | (30,287) | ||||||
Research and development expenses (R&D)
R&D expenses in the periods presented primarily relate to activities for the Company’s clinical and preclinical programs. Our research and development expenses are broken down as set forth in the table below :
| in thousands of euro | June 30, 2026 | June 30, 2025 | ||||||
| Monalizumab | (1) | (5) | ||||||
| Lacutamab | (2,706) | (3,218) | ||||||
| IPH65 | (1,277) | (1,222) | ||||||

| Personnel expenses (including share-based payments) | (6,256) | (8,996) | ||||||
| Depreciation and amortization | (187) | (257) | ||||||
| Other expenses | (2,199) | (1,546) | ||||||
| Personnel and other expenses | (8,642) | (10,800) | ||||||
| Total research and development expenses | (16,877) | (20,520) | ||||||
Innate Pharma |Half-year financial report June 30, 2026 | 8
R&D expenses decreased by €3.6 million, or 17.8%, to €16.9 million for the six months ended June 30, 2026, as compared to R&D of €20.5 million for the six months ended June 30, 2025.
R&D expenses represented a total of 68.4% and 67.8% of the total operating expenses for the six months ended June 30, 2026 and June 30, 2025, respectively.
Direct R&D expenses totaled €8.2 million for the six months ended June 30, 2026, decreased by €1.5 million, or 15.3%, to as compared to an amount of €9.7 million for the six months ended June 30, 2025. This decrease can be broken down into two factors: expenses related to clinical programs decreased by €1.0 million, primarily due to the phasing of studies (lacutamab and IPH5201 reaching maturity, discontinuation of certain preclinical studies), a decrease partially offset by the ramp-up of IPH4502, our antibody-drug conjugate (ADC).
The change in expenses related to clinical programs is attributable to: (i) an increase of €0.5 million for IPH4502, related to the completion of patient enrollment in the dose-escalation phase of the Phase 1 study; (ii) a decrease of €0.5 million for the lacutamab program, as clinical studies are reaching completion; (iii) a decrease of €1.0 million in the IPH5201 program, as recruitment for Cohort 2 was less advanced than that for Cohort 1 whose recruitment was finalized in the first half of 2025.
Personnel and other R&D expenses decreased by €2.2 million, or 20.0%, to €8.6 million for the six months ended June 30, 2026, compared to €10.8 million for the six months ended June 30, 2025. This decrease is primarily due to a reduction in personnel expenses of €2.7 million, resulting from a reduction in the R&D workforce (from 133 to 92 employees), partially offset by a €0.7 million increase in other expenses, corresponding to a provision for risks and charges.
General and administrative expenses:
General and administrative expenses decreased by €2.0 million, or 20.2%, to €7.8 million for the six months ended June 30, 2026, as compared to general and administrative expenses of €9.8 million for the six months ended June 30, 2025. General and administrative expenses represent a total of 31.6% and 32.2% of the total operating expenses for the six months ended June 30, 2026 and June 30, 2025, respectively. The table below presents our general and administrative expenses by nature for the six months ended June 30, 2026 and June 30, 2025:
| in thousands of euro | June 30, 2026 | June 30, 2025 | ||||||
| Personnel expenses (including shared-based payments) | (3,238) | (4,784) | ||||||
| Non scientific advisory and consulting | (1,185) | (1,397) | ||||||
| Other expenses (1) | (3,374) | (3,586) | ||||||
| Total general and administrative expenses | (7,797) | (9,767) | ||||||
(1) Other expenses are related to intellectual property, maintenance costs for laboratory equipment and our premises, depreciation and amortization and other selling, general and administrative expenses.
Personnel expenses include compensation paid to our employees. They totaled €3.2 million for the six months ended June 30, 2026, compared to €4.8 million for the six months ended June 30, 2025, this decrease of €1.5 million is primarily due to employees reduction (29 employees for the six months ended June 30, 2026 vs. 42 for the six months ended June 30, 2025).
Non-scientific and consulting fees consist primarily of fees for statutory audit, accounting, legal services, and recruitment. This expense item decreased by €0.2 million, or 15.2%, to €1.2 million for the six months ended June 30, 2026, compared to €1.4 million for the six months ended June 30, 2025. The decrease is primarily due to the suspension of the “At the Market” program on the Nasdaq.
Innate Pharma |Half-year financial report June 30, 2026 | 9
Other expenses decreased by €0.2 million, primarily in connection with the Director & Officer (D&O) insurance policy.
C.Net financial income (loss)
We recognized a net financial loss of €0.6 million in the six months ended June 30, 2026 as compared to €4.1 million profit in the six months ended June 30, 2025. This variance of €4.7 million mainly results from (i) a unfavorable variation in net foreign exchange gain increasing by €(3.9) million for the first half of 2026 with its unfavorable impact on the collaboration liabilities recorded during the first half of 2026 in connection with the change in the dollar exchange rate and (ii) a decrease of €0.9 million in income resulting from financial assets and fair value revaluation related to the decrease in Cash and cash equivalent and financial assets.
The table below presents the components of our net financial income (loss) for the six months ended June 30, 2026 and June 30, 2025:
| (in thousands of euro) | June 30, 2026 | June 30, 2025 | ||||||
| Interests and gain on financial assets | 279 | 793 | ||||||
| Unrealized gains on financial assets | 90 | 464 | ||||||
| Foreign exchange gains | 415 | 5,630 | ||||||
| Financial income | 783 | 6,886 | ||||||
| Foreign exchange losses | (1,224) | (2,574) | ||||||
| Paid Interests on financial liabilities | (170) | (229) | ||||||
| Financial expenses | (1,395) | (2,803) | ||||||
| Net financial income (loss) | (612) | 4,083 | ||||||
Our investment policy focuses on the absence of capital risk and, as far as possible, a guaranteed minimum performance.
For the six months ended June 30, 2026 and June 30, 2025, 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 and collaboration debt. Unrealized losses on financial assets relate to unquoted instruments.
D.Balance sheet items
Cash, cash equivalents, short-term investments and non-current financial assets amounted to €21.4m as of June 30, 2026, as compared to €44.8m as of December 31, 2025. Net cash as of June 30, 2026 amounted to €0.1m (€25.5m as of December 31, 2025). Net cash is equal to cash, cash equivalents and short-term investments less current financial liabilities. Net cash is a non-IFRS financial indicator that is reviewed by the Company’s management and that the Company believes provides useful information to investors with respect to measuring cash resources that are available for strategic investment. Net cash is not defined by IFRS and is not a substitute for “cash and cash equivalents” as reported under IFRS.

As of December 31, 2025, the company again met these criteria and benefited from the early reimbursement, with the 2025 Research Tax Credit (CIR) amounting to €6.2 million received in the first half of 2026.

F.Interim Condensed Notes to the Consolidated Financial Statements
1.The Company and key events
1.1The company
As the Group, is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. Leveraging its expertise in antibody-engineering and innovative target identification, Innate Pharma is developing innovative and differentiated next-generation antibody therapeutics.
Innate Pharma is advancing a portfolio of differentiated potential first- and/or best-in-class assets, focused on areas of high unmet medical need. Its proprietary pipeline is centered on antibody-drug conjugates (ADCs), led by IPH4502, a differentiated Nectin-4 ADC in clinical development for solid tumors, and supported by a preclinical portfolio of next-generation ADC candidates. In parallel, Innate is advancing two partnered late-stage assets: lacutamab, developed with Sobi for T-cell lymphomas, and monalizumab, developed with AstraZeneca for non-small cell lung cancer.
Innate Pharma is a trusted partner to biopharmaceutical companies such as Sanofi and AstraZeneca, as well as leading research institutions, to accelerate innovation, research and development for the benefit of patients.
Since its creation, the Company has suffered losses due to its research and development ("R&D") activities. The first half of 2026 generated a net loss of 19,623 thousand euros. As of June 30, 2026, shareholders' equity amounted to 40,508 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 drug 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 drug 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 mid-term, to be financed through partnership agreements for the development and commercialization of its drug candidates and through the issuance of new equity instruments and debt financing.
The activity of the Company is not subject to seasonal effects.
As of June 30, 2026, the Company had one wholly owned subsidiary: Innate Pharma, Inc., incorporated under the laws of Delaware in 2009. This subsidiary is fully consolidated.
Innate Pharma is based in Marseille, France and listed on Euronext in Paris and Nasdaq in the United States, and had 120 full time equivalent employees as of June 30, 2026.
1.2Key events for the six-month period ended June 30, 2026
None.
2.Basis of presentation and statement of compliance
2.1Basis of preparation
Innate Pharma |Half-year financial report June 30, 2026 | 19
The interim condensed consolidated financial statements were closed by the Chief Executive Officer, approved and authorized by the Board of Directors on September 16, 2026 upon recommendation of the Audit Committee on September 11, 2026.
They have been prepared in accordance with IAS 34, ‘Interim Financial Reporting’ as issued by the International Accounting Standard Board (“IASB”), 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 as of June 30, 2026.
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, 2025.
The accompanying consolidated financial statements are prepared in accordance with generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.
The Group has historically financed its operations through revenues generated from collaboration and licensing agreements, public funding, capital increases and other financing arrangements.
As of June 30, 2026, based on the Group’s cash position at that date and management’s cash flow forecasts, the Group would not have had sufficient financial resources to fund its planned operations over the twelve-month period following the approval of these interim condensed consolidated financial statements.
On August 10, 2026, the Company entered into a strategic licensing and commercialization agreement with Swedish Orphan Biovitrum AB (“Sobi”) relating to lacutamab. Under the terms of the agreement, the Company is entitled to receive an upfront payment of USD 75 million upon closing of the transaction, in addition to potential future development, regulatory and commercial milestone payments and royalties.
The conditions required for the effectiveness of the agreement, including those relating to antitrust regulatory clearances and manufacturing capacity arrangements, have been satisfied prior to the approval of these interim condensed consolidated financial statements. Management therefore expects the upfront payment of USD 75 million to be received in accordance with the contractual terms.
In addition, the Company successfully completed on August 14, 2026 an equity financing transaction through a private placement of ordinary shares, generating gross proceeds of approximately €30 million.
Taking into account the expected proceeds from the Sobi transaction together with the proceeds received from the capital increase, management estimates that the Group has sufficient financial resources to fund its planned operations until the first quarter of 2028.
Accordingly, the Board of Directors has adopted the going concern basis in preparing these interim condensed consolidated financial statements.
Except for share data and per share amounts, the Consolidated Financial Statements are presented in thousands of euro. Amounts are rounded up or down to the nearest whole number for the calculation of certain financial data and other information contained in these accounts. Accordingly, the total amounts presented in certain tables may not be the exact sum of the preceding figures
2.2Use 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
Innate Pharma |Half-year financial report June 30, 2026 | 20
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 2.w) of the appendix to the consolidated financial statements as of December 31, 2025 filed with SEC (20-F) on April 1st, 2026. As of June 30, 2026, the Company has not identified any other significant estimates and judgments that could have an impact on the consolidated financial statements.
2.3Recently issued accounting standards and interpretations
The following new standards, amendments to existing standards and interpretations have been published and are applicable on January 1, 2026 and, as such, they have been adopted by the Company:
•Amendment to IFRS 9 : Classification and Measurement of Financial Instruments;
•Amendments to IFRS 7 and IFRS 9: Clarification on Nature-dependent electricity contracts.
These recent amended standards have no impact on the interim condensed consolidated financial statements.
The following new standards, amendments to existing standards and interpretations have been published but are not yet applicable on January 1, 2026 or have not yet been adopted by the European Union, and have not been applied early:
• Amendment to IAS 21 : Effects of Changes in Foreign Exchange Rates - Lack of Exchangeability;
•IFRS 18 : Presentation of financial statements;
These standards have not been early applied. Impact studies are in progress.
The accounting rules and valuation principles applied for the financial statements at June 30, 2026 are the same as those applied at December 31, 2025 .
2.4Translation of transactions denominated in foreign currency
Foreign currency transactions are translated into the functionnal currency using the following exchange rates:

| Cash, cash equivalents and financial assets | ||||||||
Cash and cash equivalents are mainly composed of current bank accounts, interest-bearing accounts and fixed-term accounts and mutual funds units (with short-term maturities) held with various banking institutions.
As of June 30, 2026, the Company also holds shares in three mutual funds. The risk profiles of these funds are rated from 1 to 7 by the financial institution that manages and markets these funds (1 being the lowest risk profile).When the maturity of shares in mutual funds is longer than one year, they are classified as non-current financial instruments.
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, 2026 and December 31, 2025, the amount of cash, cash equivalents and financials assets denominated in US dollars amounted to €4,300 thousand and €7,078 thousand, respectively.
Changes in short-term investments and non-current financial assets for the six months ended June 30, 2026 and June 30, 2025 are the following:

(1)The amount of €6,174 thouand recognized in current receivables as of December 31, 2025 corresponds to the Crédit d’impôt Recherche (CIR) for the 2025 tax year following the fact that the Company met the eligibility criteria for the SME status as of December 31, 2025. Thus, the CIR for the 2025 represented a current receivable which will in principle be offset against the French corporate income tax due by the Company or refunded if necessary. In accordance with that principles described in Note 2.q, the research tax credit (Crédit d’Impôt Recherche or “CIR”) is recognized as other operating income in the year to which the eligible research expenditure relates. The amount of CIR recognized as current receivables as of June 30, 2026 is 6,174 thouand of CIR for the first half of 2026.
(2)As of June 30, 2026, and December 31, 2025 the prepaid expenses includes amounts of €375 thousand and €500 thousand, respectively, relating to the guarantee fees in line with the two State Guaranteed Loans from Société Générale and BNP Paribas. Following the extension of these two loans repayment for an additional period, the full amount of the guarantee fee over the additional five-year period has been recognized as an operating expense in 2022. As of June 30, 2026 and December 31, 2025, an adjustment is made through the prepaid accounts to reflect the fact that the expenses are related to the fiscal year (see note 9).
(3)As of June 30, 2026, and December 31, 2025, advances had been paid to suppliers. These advances will be deducted from subsequent payments in accordance with the terms of the contracts.
The net book value of the receivables is considered to be a reasonable approximation of their estimated fair value. No valuation allowance was recognized on trade receivables and others as the credit risk of each debtor was considered as not significant.

The Company received the funds related to these two loans on December 27 and 30, 2021 respectively. Both loans have an initial maturity of one year with an option to extend to five years usable from August, 2022. They are 90 % guaranteed by the French government as part of the package of measures put in place by the French government to support companies during the COVID-19 pandemic. In August 2022, the Company has requested the extension of these two loans repayment for an additional period of five years starting in 2022 and including a one-year grace period. Consequently, the Company has obtained agreements from Société Générale and BNP Paribas. The effective interest rates applied to these contracts during the additional period are 1.56 % and 0.95 % for Société Générale and BNP Paribas loans, respectively, excluding insurance and guarantee fees, with an amortization exemption for the entire year 2023. During this grace period, the Company will only be liable for the payment of interest and the guarantee fees. The amortization of the two loans began in 2024 for a period of four years . The state guarantee fees amounts to €877 thousand and €379 thousand for Société Générale and BNP Paribas loans respectively.

This loan amounting to a maximum of €15,200 thousand will be raised during the period of the construction in order to pay the supplier payments as they become due. As of December 31, 2018 and 2019, the loan was raised at an amount of €1,300
The loan release period was limited to August 30, 2019. On August 30, 2019, the Company drew down the remaining portion of the €15,200 thousand loan granted, for an amount of €13,900 thousand. The reimbursement of the capital has begun in August 30, 2019 and will proceed until August 30, 2031 (12 years). Given the development of its portfolio and in particular the refocusing of its activities on research and development, the Company has for the time being suspended the project to build its new head office on the land acquired in Luminy. In the meantime, the loan will be used to finance several structuring projects (improvement of the information

The security interest on the pledge financial instruments will be released in accordance with the following schedule: €4,200 thousand in July 2024, €5,000 thousand in August 2027 and €6,000 thousand in August 2031. Following the release of the pledge on the €4.2 m financial instrument that had reached maturity, the Company received this amount in July 2024.

As a reminder, the Company announced that, in June 2023, the first patient was dosed in a Sanofi-sponsored Phase 1/2 clinical trial evaluating IPH6401/SAR'514 in relapsed or refractory Multiple Myeloma. No milestone payment has been recognized as of June 30, 2026.
d) Revenue related to Sanofi research collaboration and licensing agreement (2022)
In December 2022, the Company entered into a research collaboration and license agreement with Genzyme Corporation, a wholly owned subsidiary of Sanofi (“Sanofi”), under which the Company granted Sanofi an exclusive license to Innate’s B7-H3 ANKET® program and options for two additional targets.
In March 2023, Innate Pharma received an upfront payment of €25 million under its research, collaboration and license agreement with Sanofi. This amount consisted of €18.5 million relating to the exclusive license to the B7-H3
Innate Pharma |Half-year financial report June 30, 2026 | 34
technology, which was recognized in profit or loss in June 2023; €1.5 million relating to research activities to be performed over a three-year period, recognized as revenue on a straight-line basis through November 2026; and €5 million relating to the two additional license options, recognized as contract liabilities until their expiration or until the options are exercised.
In December 2023, Sanofi exercised one of its license options for an ANKET® program, resulting in the recognition of €2.5 million in revenue and the payment of a €15 million milestone, of which €13.3 million related to the license was recognized immediately in revenue and €1.7 million related to research activities. These research activities were discontinued following the termination of the agreement in October 2024, which led to the full recognition of the €1.7 million in revenue in 2024. As a result, Innate regained the rights to the IPH67 program, while Sanofi retains a right to compensation on any potential future revenues.
On January 24, 2026, following the expiration of the deadline to exercise the license option on an identified target, the revenue of €2.5 million has been fully recognized. Sanofi always has a right on a non-exclusive license option for an additional target, exercisable up to January 24, 2028. This option is not linked with any other revenue.

STATUTORY AUDITORS' REVIEW REPORT ON THE HALF-YEARLY FINANCIAL INFORMATION
This is a free translation into English of the statutory auditors’ review report on the half-yearly financial information issued in French and is provided solely for the convenience of English-speaking users. This report includes information relating to the specific verification of information given in the Group’s half-yearly management report. This report should be read in conjunction with, and construed in accordance with, French law and professional standards applicable in France.
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, 2026 to June 30, 2026;
•the verification of the information presented in the half-yearly management report.
These condensed half-yearly consolidated financial statements are the responsibility of the Board of Directors. 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- standard of the IFRSs as adopted by the European Union applicable to interim financial information.
Specific verification
We have also verified the information presented in half-yearly management report on the condensed half-yearly consolidated financial statements subject to our review.
We have no matters to report as to its fair presentation and consistency with the condensed half-yearly consolidated financial statements.
