HALF-YEAR MANAGEMENT REVIEW
The key elements of Innate Pharma’s financial results for the first half of 2024 are as follows:
Cash, cash equivalents and financial assets (current and non-current) amounting to €102.1m (million euros) as of June 30, 2024 (€102.3m as of December 31, 2023). At the same date, the financial liabilities amounted to €35.5m, including €26.6m of non-current liabilities (€39.9m as of December 31, 2023, including €31.0m of non-current financial liabilities).
Revenue and other income amounting to €12.3m (€40.2m for the first half of 2023). This amount mainly results from collaboration and licensing revenue (€8.3m) and from research tax credit (€4.1m). Revenue from collaboration and licensing agreements mainly result from the agreements with AstraZeneca/Medimmune and Sanofi/Genzyme.
Operating expenses amounting to €38.7m (€40.6m for the first half of 2023), of which 75.2% are related to research and development. Research and development expenses amount to €29.1m compared to €31.5m for the first half of 2023 and decrease by €2.4m, mainly explained by lower personnel and other R&D expenses by €2.2 millions (-15.4%). This decrease is due to an non-recurring amortization charge in the first half of 2023, related to the IPH5201 rights (full amortization of the additional €2.0 million invoice from Orega Biotech following the dosing of the first patient in the Phase 2 MATISSE clinical trial in June 2023). Additionally, direct R&D expenses, which slightly decreased by €0.2 million, remained at €17.1 million, with an acceleration in preclinical spending related to the Antibody-Drug Conjugates (ADC) program offsetting the decrease in expenses related to certain more mature clinical-stage programs.
General expenses amounting to €9.6 million (compared to €9.1 million in the first half of 2023), an increase of €0.4 million. This increase is due to a €0.4 million decrease in personnel expenses linked to a reduction of the administrative staff (39 employees as of June 30, 2024, compared to 45 as of June 30, 2023), bringing personnel expenses to €4.0 million in the first half of 2024, more than offset by a €0.3 million increase in non-scientific and consulting fees, which amounts to €1.9 million in the first half of 2024, resulting from greater reliance on recruitment agencies, and (III) a €0.5 million increase in other expenses, mainly due to the derecognition of returned spaces in the first half of 2023 (as a reminder, on March 13, 2023, the Company signed an amendment to the lease of the 'Le Virage' building, aimed at reducing the area of leased premises) and the sale of related furniture during the same period, which led to an exceptional reduction in these charges in the first half of 2023.
A net loss for the first half of 2024 amounting to €24.8m (compared to net income of €1.7m for the first half of 2023).
Note on change of accounting standards during the period
Application of the following amended standards is mandatory for the first time for the financial period beginning on January 1, 2024 and, as such, they have been adopted by the Company:
Amendements to IAS 1 : Classification of liabilities with covenants;
Amendements to IAS 7 and IFRS 7 : Supplier finance arrangements;
Amendements to IFRS 16 : Lease liability in a sale and leaseback.
Those amended standards have no impact on the interim condensed consolidated financial statements.

A.Revenue and other income
Revenue and other income resulted from collaboration and licensing agreements and government financing for research expenditure. They decreased by €27.9 million, to €12.3 million for the six months ended June 30, 2024, as compared to revenue and other income of €40.2 million for the six months ended June 30, 2023.

Revenue from collaboration and licensing agreements
Revenue from collaboration and licensing agreements decreased by €27.1 million, to €8.3 million for the six months ended June 30, 2024, as compared to revenue from collaboration and licensing agreements of €35.3 million for the six months ended June 30, 2023. 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 and with Takeda in 2023. 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)897616
Revenue from collaboration and licensing agreements8,29335,344

Proceeds from collaboration and licensing agreements

For monalizumab, these amounts result from the partial recognition of the $250.0 million non-refundable upfront payment and the $100 million milestone regarding the exercise of the option received in June 2015 and October 2018 from AstraZeneca. The additional payment of $50.0 million received from AstraZeneca in December 2020 triggered by the dosing of the first patient in the Phase 3 trial evaluating monalizumab was treated in full as a collaboration commitment ("collaboration liability" in the consolidated balance sheet) in view of the commitment linked to the agreement for the Phase 1/2 (co-financing) and Phase 3 studies (amendment signed in September 2020). Consequently, this additional payment has no impact on the transaction price.
In addition to these amounts, AstraZeneca made an additional payment of $50.0 million in June 2022, triggered by the treatment of the first patient in a second Phase 3 trial evaluating monalizumab in April 2022. This additional
Innate Pharma |Half-year financial report June 30, 2024 | 6




payment has been treated as a collaboration commitment ("collaboration liability" in the consolidated balance sheet) for an amount of $36.0 million in view to the contractual commitment linked to the Phase 1/2 studies (co-funding under the initial contract). The remaining $14.0 million was treated as a change in estimate of the transaction price, recognized in the income statement in line with the progress of the Phase 1/2 studies.
The amounts not yet recognized in revenue are classified as deferred revenue.
Proceeds related to monalizumab - AstraZeneca:
Revenue related to monalizumab decreased by €6.5 million, to €3.0 million for the six months ended June 30, 2024, as compared to €9.5 million for the six months ended June 30, 2023. This decrease is mainly due to the recognition of increased revenue in the first six months of 2023. Indeed, as of June 30, 2023, the Company had analyzed the cost base used to calculate the percentage of completion of Phase 1/2 trials in connection with their progress. This analysis led to a reduction in the cost base through a re-estimation of projected expenses. As a result, this adjustment on the cost base had a positive impact on the percentage of completion and led to the recognition of additional revenue of €5.9 million for the first half of 2023 which was not replicated in 2024.
As of June 30, 2024, the deferred revenue related to monalizumab is €2.0 million entirely classified as “Deferred revenue—Current portion” in connection with the progress of Phase 1/2 trials.
Proceeds related to Sanofi licensing and collaboration agreement (2016) :
Revenue related to the license and collaboration agreement signed with Sanofi in 2016 increased by €2.0 million, to €4.0 million for the six months ended June 30, 2024, as compared to €2.0 million for the six months ended June 30, 2023. On April 15, 2024, the Company announced the treatment of the first patient in the Phase 2 dose expansion part of the Sanofi-sponsored clinical trial evaluating NK Cell Engager SAR443579/ IPH6101 in various blood cancers. Under the terms of the 2016 agreement, this trial progress triggered a milestone payment of €4.0 million fully recognized in revenue during the first quarter of 2024. This amount was received by the Company on May 17, 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. As provided by the licensing agreement signed in 2016, Sanofi made a milestone payment of €2.0 million, fully recognized in revenue as of June 30, 2023. This amount was received by the Company on July 21, 2023.
Proceeds related to Sanofi research collaboration and licensing agreement (2022) :
As a reminder, on December 19, 2022, the Company announced that it had entered into a research collaboration and license agreement with Genzyme Corporation, a wholly-owned subsidiary of Sanofi (“Sanofi”) pursuant to which the Company granted Sanofi an exclusive license on the Innate Pharma's B7-H3 ANKET® program and options on two additional targets. On January 25, 2023, the Company announced the expiration of the waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976 and the effectiveness of the licensing agreement as of January 24, 2023. Consequently, the Company received an upfront payment of €25.0 million in March 2023, including €18.5 million for the exclusive license, €1.5 million for the research activities and €5.0 million for the option on two additional targets.
The Company considers that the license to the B7-H3 technology is a right to use the intellectual property granted exclusively to Sanofi from the effective date of the agreement. As such, the €18.5 million upfront payment relating to the exclusive license was fully recognized in revenue as of June 30, 2023.
The Company will perform collaborative research activities for an initial estimated three-year period from the effective date of the collaboration, i.e. January 24, 2023. During this period, Sanofi and Innate will collaborate and work on research activities as defined in the research program described in the agreement. Consequently, the
Innate Pharma |Half-year financial report June 30, 2024 | 7




corresponding upfront payment of €1.5 million is recognized on a straight-line basis over the duration of the research activities that the Company has agreed to carry out. As a result, a €0.2 million has been recognized in revenue as of June 30, 2024 and June 30, 2023. Amounts not recognized in revenue are classified as deferred revenue—current portion for €0.4 million and deferred revenue—non-current portion for €0.5 million.
As previously announced, on December 19, 2023, the Company announced that Sanofi had exercised an option for one of the two targets. As a consequence, the Company recognized related income of €2.5 million as of December 31, 2023. This option exercise also resulted in a milestone payment of €15.0 million, including €13.3 million in respect of the exclusive license, which was fully recognized in income as of December 31, 2023, and €1.7 million in respect of research activities to be carried out by the Company, which will be recognized in income on a straight-line basis over the duration of the research work that the Company has agreed to carry out. Sanofi and Innate will collaborate and work on the research activities defined in the contractual research program. This work began during the first half of 2024. An amount of €0.2 million has been recognized in revenue as of June 30, 2024. Amounts not recognized in revenue are classified as deferred revenue—current portion for €0.4 million and deferred revenue—non-current portion for €1.1 million.
Proceeds related to Takeda licensing agreement (2023) :
Revenues under the license agreement signed with Takeda in 2023 are nil for the first half of 2024, compared to €4.6 million for the first half of 2023. On April 3, 2023, the Company announced that it has entered into an exclusive license agreement with Takeda under which Innate grants Takeda exclusive worldwide rights to research and develop antibody drug conjugates (ADC) using a panel of selected Innate antibodies against an undisclosed target, with a primary focus in Celiac disease. Takeda will be responsible for the future development, manufacture and commercialization of any potential products developed using the licensed antibodies. As such, the Company considers that the license granted is a right to use the intellectual property, which is granted fully and perpetually to Takeda. The agreement does not stipulate that Innate's activities will significantly affect the intellectual property granted during the life of the agreement. Consequently, the $5.0 million (or €4.6 million) initial payment, received by the Company in May 2023, was fully recognized in revenue as of June 30, 2023.
Invoicing of research and development costs - AstraZeneca:
Pursuant to our agreements with AstraZeneca, external research and development costs related to IPH5201 are equally shared between Innate Pharma and AstraZeneca, in accordance with the amendment signed in June 2022. These costs are invoiced back on a quarterly basis.
Revenue from invoicing of research and development costs for the six months ended June 30, 2024 increased by €0.3 million as compared to the six months ended June 30, 2023. The change between the two periods is mainly explained by the increase in research and development costs incurred by the Company under these agreements during the first half of 2024 in line with the clinical trial progress.
Government financing for research expenditures
The table below details government financing for research expenditures for the six months ended June 30, 2024 and 2023.

Research tax credits4,0504,854 (1)
Grants2
Government financing for research expenditures4,0524,854
Innate Pharma |Half-year financial report June 30, 2024 | 8




(1) As of June 30, 2023, the amount is mainly composed of (i) the research tax credit calculated and recognized for the first half of 2023 for an amount of €5.0 million from which is subtracted (ii) a provision amounting to €0.2 million relating to the additional provision in connection with the tax inspection carried out in 2022 by the French tax authorities relating to the 2019 and 2020 financial years, as well as the research tax credit and the accuracy of its calculation for the 2018 to 2020 financial years.
Government financing for research expenditures decreased by €0.8 million, or 16.5%, to €4.1 million for the six months ended June 30, 2024 as compared to €4.9 million for the six months ended June 30, 2023. This change is mainly due to the €1.5 million decrease in the research tax credit, resulting from (i) the absence of depreciation for IPH5201 rights in the first half of 2024, compared with the depreciation recognized in the first half of 2023 following the additional payment of €2.0 million to Orega Biotech following the dosing of the first patient in the MATISSE Phase 2 clinical trial, (ii) a decrease in amortization expense for the monalizumab intangible asset, which is nearing the end of its amortization period, and (iii) a reduction in eligible R&D personnel costs.
However, these decreases were offset by a €0.5 million increase in Research tax credits (Crédits d’impôt Recherches or “CIR”) from public and private R&D subcontracting expenses over the period included in the calculation of the research tax credit, due to the inclusion, for the first half of 2024, of R&D expenses incurred with a third party whose approval was under renewal as of June 30, 2023, and whose expenses had been excluded from eligible expenses for that period.
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, 2024 and 2023:

General and administrative expenses(9,582)(9,144)
Operating expenses(38,657)(40,597)

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 :

Other expenses(2,603)(2,458)
Personnel and other expenses(12,005)(14,188)
Total research and development expenses(29,076)(31,453)

R&D expenses decreased by €2.4 million, or 7.6%, to €29.1 million for the six months ended June 30, 2024, as compared to R&D of €31.5 million for the six months ended June 30, 2023.
R&D expenses represented a total of 75.2% and 77.5% of the total operating expenses for the six months ended June 30, 2024 and 2023, respectively.
Direct R&D expenses decreased by €0.2 million, or 1.1%, to €17.1 million for the six months ended June 30, 2024, as compared to an amount of €17.3 million for the six months ended June 30, 2023. This variation is mainly explained by a €2.5 million increase in expenses related to preclinical programs, particularly in the field of Antibody-Drug Conjugates (ADC), offset by a €2.7 million decrease in expenses related to clinical programs.
The variance relating to clinical programs is composed of the following items: (i) a €0.5 million increase related to recruitment costs for the Phase 2 MATISSE trial of the IPH5201 program, offset by (ii) a €1.4 million decrease in expenses for the IPH65 program, whose first patient was dosed in March 2024, (iii) a €1.5 million decrease in expenses for the lacutamab program, and (iv) a €0.5 million decrease in expenses related to the monalizumab program, decrease related to maturation of Phase I/II clinical trials under the collaboration with AstraZeneca.
Additionally, as of June 30, 2024, collaboration liabilities related to monalizumab and the agreements signed with AstraZeneca in April 2015, October 2018, and September 2020 amounted to €52.1 million, as compared to collaborations liabilities to €52.7 million as of December 31, 2023. This €0.5 million decrease mainly results from (i) net reimbursements of €2.4 million made to AstraZeneca in the first half of 2024 related to the co-funding of the monalizumab program, including the INTERLINK-1 Phase 3 trial launched in October 2020 and PACIFIC-9 launched in April 2022, and (ii) the increase in the collaboration commitment by €1.7 million due to exchange rate fluctuations observed during the period for the euro-dollar exchange rate.
Personnel and other expenses allocated to R&D decreased by €2.2 million, or 15.4%, to €12.0 million for the six months ended June 30, 2024, as compared to an amount of €14.2 million for the six months ended June 30, 2023. This decrease is mainly explained by amortization charges related to the IPH5201 rights, following the full amortization of the additional €2.0 million invoice from Orega Biotech after the dosing of the first patient in the Phase 2 MATISSE clinical trial in June 2023.
Innate Pharma |Half-year financial report June 30, 2024 | 10




General and administrative expenses:
General and administrative expenses increased by €0.4 million, or 4.8%, to €9.6 million for the six months ended June 30, 2024, as compared to general and administrative expenses of €9.1 million for the six months ended June 30, 2023. General and administrative expenses represent a total of 24.8% and 22.5% of the total operating expenses for the six months ended June 30, 2024 and 2023, respectively. The table below presents our general and administrative expenses by nature for the six months ended June 30, 2024 and 2023:
in thousands of euroJune 30, 2024June 30, 2023
Personnel expenses (including shared-based payments)(4,001)(4,367)
Non scientific advisory and consulting(1,934)(1,662)
Other expenses (1)(3,648)(3,116)
Total general and administrative expenses(9,582)(9,144)

(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 expense includes the compensation paid to our employees. They amounted €4.0 million for the six months ended June 30, 2024, as compared to €4.4 million for the six months ended June 30, 2023. The decrease of €0.4 million is mainly due to a reduction of administrative workforce.
Non-scientific advisory and consulting expenses mostly consist of auditing, accounting, legal fees and hiring services. Non-scientific advisory and consulting expenses increased by €0.3 million, or 16.4%, to €1.9 million for the six months ended June 30, 2024 as compared to €1.7 million for the six months ended June 30, 2023. This increase is mainly due to greater reliance on recruitment agencies.
The rise in other expenses of €0.5m mainly results from rent, maintenance, and upkeep costs (primarily related to property rentals; a exceptional effect related to the derecognition of returned spaces—as a reminder, on March 13, 2023, the Company signed an amendment to the lease of the "Le Virage" building, aimed at reducing the area of leased premises. The effective date of the lease amendment is March 15, 2023) as well as a €0.2 million increase in other net income and expenses (primarily related to the sale of office furniture following the reduction of leased spaces).
C.Net financial income (loss)
We recognized a net financial income of €1.5 million in the six months ended June 30, 2024 as compared to €2.1 million in the six months ended June 30, 2023. This variance mainly results from the unfavorable evolution of the dollar exchange rate and its impact on foreign exchange recorded during the first half of 2024, with a net foreign exchange loss of €0.9 million for the first half of 2024 as compared to a net foreign exchange gain of €0.4 million for the first half of 2023. The negative currency impact was offset by an increase in the fair value of certain financial instruments (net gain of €1.5 million for the six months ended June 30, 2024 as compared to a net gain of €1.0 million for the six months ended June 30, 2023) and by an increase in interest income of €1.3 million in first-half 2024 as compared to €1.0 million in first half of 2023.
The table below presents the components of our net financial income (loss) for the six months ended June 30, 2024 and 2023:

Interest on financial liabilities(300)(324)
Financial expenses(2,064)(966)
Net financial income (loss)1,5492,116
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, 2024 and 2023, 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.

D.Balance sheet items
Cash, cash equivalents, short-term investments and non-current financial assets amounted to €102.1m as of June 30, 2024, as compared to €102.3m as of December 31, 2023. Net cash as of June 30, 2024 amounted to €82.9m (€83.5m as of December 31, 2023). 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. Management recognizes that the term net cash may be interpreted differently by other companies and under different circumstances.
As of June 30, 2024, the Company has been primarily financed by revenue from its collaboration, licensing agreements since 2011 (€579.1m in total, or $656.1m), and by issuing new shares (€306.4m in total excluding share-based 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 (interest free loan for Innovation). As of June 30, 2023, the Company is not liable for any reimbursement in respect of these reimbursable advances and PTZI loan. The Company also has bank borrowings of €34.9m, including €25.2m of State Guaranteed Loans (“Prêts Garantis par l’Etat”) as of June 30, 2024 and €9.6m loans subscribed with Société Générale for the construction of its head office as well as €0.6m of lease liabilities.
The research tax credit (Crédit d’Impôt Recherche) (the “Research Tax Credit” or “CIR”) granted by the French tax authorities in order to encourage companies to conduct technical and scientific research. Companies that can justify that these expenses meet the required criteria receive such grants in the form of a refundable tax credit that can be used for the payment of taxes due for the period in which the expense was incurred and for the next three years or refunded if necessary upon expiry of such a period. As a reminder, the Company has benefited from the early repayment of the Research Tax Credit (Crédit Impôt Recherche - CIR) until December 31, 2019. As of December 31 2019 and December 31, 2023, the Company no longer met the eligibility criteria for this status (criteria not met after year-end analysis). As a result, the CIR for 2019 and 2020 represented a receivable from the
Innate Pharma |Half-year financial report June 30, 2024 | 12




French Treasury, which was refunded to the Company in January 2024 for €16.7 million and July 2024 for €12.8 million. The CIR calculated in respect of 2023 and the first half of 2024 is recognized as a non-current receivable. For fiscal years 2021 and 2022, the Company met the definition of an SME under European Union criteria and was therefore entitled to early repayment of the CIR in 2022 in respect of the 2021 tax year and in July 2023 in respect of the 2022 tax year. Since its creation and at the date of this report, the Company has benefited from CIR reimbursements for a net amount of €128.9m.
The other key balance sheet items as of June 30, 2024 are as follows:
Deferred revenue of €6.9m (including €4.1m booked as ‘Deferred revenue – non-current portion’) and collaboration liabilities amounting to €52.1m (including €41.9m booked as ‘Collaboration liabilities - non-current portion’) relating to the remainder of the initial payment from AstraZeneca not yet recognized as revenue or used as part of the co-financing of the monalizumab program with AstraZeneca;
Receivables from the French government amounting to €26.6m in relation to the research tax credit for 2020, 2023 and the six-month period ended June 30, 2024;
Shareholders’ equity of €28.8m including the net loss for the first half of 2024 of €24.8m.

E.Cash-flow items
As of June 30, 2024, cash and cash equivalents amounted to €70.0m, a decrease of €0.6m compared to December 31, 2023.
The following table sets forth cash flow data for the six months ended June 30, 2024 and 2023:
in thousands of euroJune 30, 2024June 30, 2023

Effect of the exchange rate changes(257)145
Net increase / (decrease) in cash and cash equivalents:(615)(12,811)

Cash flows from / (used in) operating activities:
Net cash flow from operating activities increased by €14.5 million to €3.0 million for the six months ended June 30, 2024 as compared to net cash flow used in operating activities of €11.5 million for the six months ended June 30, 2023.
Net cash flow from operating activities for the first half of 2024 notably includes (i) the collection of €15.0 million in January 2024 following Sanofi's decision to exercise one of its two license option for an NK Cell Engager program in solid tumors, derived from the Company's ANKET® (Antibody-based NK Cell Engager Therapeutics) platform, pursuant to the terms of the research collaboration and license agreement signed in December 2022, (ii) the collection in May 2024 of €4.8 million (including value-added tax) the treatment of the first patient in the Phase 2 dose expansion part of the Sanofi-sponsored clinical trial evaluating NK Cell Engager SAR443579/ IPH6101 in various blood cancers and (iii) the repayment by the French Treasury of the research tax credit receivable relating to the 2019 financial year for an amount of €16.7 million during the first quarter of 2024, as well as the carry-back receivable for an amount of €0.3 million.
Innate Pharma |Half-year financial report June 30, 2024 | 13




As a reminder, for the first half of 2023, the net cash flow used in operating activities included (i) the €25.0 million upfront payment received from Sanofi in March 2023 following the effectiveness of the research collaboration and licensing agreement signed in December 2022 under which the Company granted Sanofi an exclusive license to Innate Pharma's B7-H3 ANKET® program and options on two additional targets, but also (ii) the €4.6 million ($5.0 million) upfront payment received from Takeda following the signing of an exclusive licensing agreement which the Company grants Takeda exclusive worldwide rights for the research and development of certain antibody drug conjugates (ADCs) (please refer to Note 20.Events after the reporting date).
Restated for these transactions linked to collaboration agreements and other non-recurring items such as the CIR refund, net cash flow used in operating activities for the first half of 2024 decreased by €7.3 million as compared to the first half of 2023. This change mainly results from lower net payments to suppliers and personnel costs.
Cash flows from / (used in) investing activities:
Net cash flow from investing activities for the six months ended June 30, 2024 was €0.9 million and was mainly composed of a disposal of a current financial instrument which generated a net cash collection of €1.2 million partially offset by acquisitions of property, plant and equipment and intangible assets for a net amount €0.3 million.
Net cash flow used in investing activities was €0.2 million for the six months ended June 30, 2023 and was mainly comprised of acquisitions of property, plant and equipment and intangible assets net of disposals.
The Company has not made any other significant investments in tangible, intangible or significant current and non-current financial assets during the first half of 2024 and 2023.
Cash flows from / (used in) financing activities:
Net cash flow used in financing activities for the six months ended June 30, 2024 was €4.3 million as compared to net cash flow used in financing activities of €1.2 million the six months ended June 30, 2023. These consumptions are mainly related to repayments of financial liabilities. Their increase over the period is related to the two State Guaranteed Loans, for which principal amortization began in the first quarter of 2024. As a reminder, the Company benefited from a one-year grace period in 2023, during which only interests and guarantee fees were paid.

F.Interim Condensed Notes to the Consolidated Financial Statements
1.The Company and key events
1.1The company
Innate Pharma SA (the “Company” and, with its subsidiary, referred to as the “Group”), is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. Its innovative approach aims to harness the innate immune system through therapeutic antibodies and its ANKET® (Antibody-based NK cell Engager Therapeutics) proprietary platform. Innate’s portfolio includes lead proprietary program lacutamab, developed in advanced form of cutaneous T cell lymphomas and peripheral T cell lymphomas, monalizumab developed with AstraZeneca in non-small cell lung cancer, as well as ANKET® multi-specific NK cell engagers to address multiple tumor types. 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 2024 generated a net loss of 24,764 thousand euros. As of June 30, 2024, shareholders' equity amounted to 28,796 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, 2024, the Company had one wholly owned subsidiary: Innate Pharma, Inc., incorporated under the laws of Delaware in 2009. The subsidiary is consolidated according global integration.
Innate Pharma is based in Marseille, France and listed on Euronext Paris and Nasdaq in the United States., and had 168 full time equivalent employees as of June 30, 2024.
1.2Key events for the six-month period ended June 30, 2024

On April 15, 2024, the Company announced the treatment of the first patient in the Phase 2 dose expansion part of the Sanofi-sponsored clinical trial evaluating NK Cell Engager SAR443579/ IPH6101 in various blood cancers.

free shares with a nominal value of €0.05 issued free of charge by deduction from the share premium, with a creation of 38,100 ordinary shares with a nominal value of €0.05 and an issue price of €2.45 (i.e an increase in share premium of €91,440).

2.Basis of presentation and statement of compliance
2.1Basis of preparation
The interim condensed consolidated financial statements as of June 30, 2024 and for the six-months period ended June 30, 2024 and 2023 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 loss-making 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 closed by the Executive Board, approved and authorized by the Supervisory Board on September 11, 2024 upon recommendation of the Audit Committee on September 10, 2024.
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.
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, 2023.
The results of the operations for the six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 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.

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 and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period.
Innate Pharma |Half-year financial report June 30, 2024 | 22




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, 2023 filed with SEC (20-F) on April 2, 2024. As of June 30, 2024, 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
Application of the following amended standards is mandatory for the first time for the financial period beginning on January 1, 2024 and, as such, they have been adopted by the Company:
Amendments to IAS 1 : Classification of liabilities with covenants;
Amendments to IAS 7 and IFRS 7 : Supplier finance arrangements;
Amendments to IFRS 16 : Lease liability in a sale and leaseback.
Those amended standards have no impact on the interim condensed consolidated financial statements.
The Company has not opted for the early application of any standards whose application would be mandatory from subsequent financial years.
2.4Translation of transactions denominated in foreign currency
Foreign currency transactions are translated into the functionnal currency using the following exchange rates:

(1) This amount corresponds to the additional invoice received from Orega Biotech for the rights relating to IPH5201 following the first patient dosed in the Phase 2 MATISSE clinical trial in June 2023, in accordance to the agreement signed in 2019. This additional invoice is fully amortized as of June 30, 2023 and paid on July 2023.
(2) As of June 30, 2024, this amount included the amortization of rights related to the monalizumab for an amount of €294 thousand. As of June 30, 2023, this amount includes the amortization of the additional payment made to Orega Biotech in 2023 for and amount of €2,000 thousand and the amortization of rights related to the monalizumab for an amount of €651 thousand.

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 has reassessed the anticipated residual duration of the Phase 2 trials as of June 30, 2024 and estimated that it would be fully amortized by 2024, which is the same estimation as of December 31, 2023, as a result of the completion of some trials and by modifying the estimated end dates relating to certain cohorts.
The net book values of the monalizumab rights were €119 thousand and €416 thousand as of June 30, 2024 and December 31, 2023, respectively.
IPH5201 (Anti-CD39) rights acquired from Orega Biotech
On January 4, 2016, the Company and Orega Biotech entered into an exclusive licensing agreement by which Orega Biotech granted the Company full worldwide rights to its program of first-in-class anti-CD39 checkpoint inhibitors. The upfront payment paid by the Company to Orega Biotech has been recognized as an intangible asset in the consolidated financial statements for the year ended December 31, 2016. Criteria relating to the first development milestone were reached in December 2016. Consequently, the amount of this milestone was recognized as an intangible asset in addition to the initial payment. In June 2019, the Company also paid Orega Biotech €7.0 million in relation to the anti-CD39 program as consideration following the collaboration and option agreement signed on October 22, 2018 with AstraZeneca regarding IPH5201. Under this agreement, the Company also paid in April and
Innate Pharma |Half-year financial report June 30, 2024 | 26




June 2020, respectively €2.5 and €0.2 million to Orega Biotech following the first Phase 1 dosing relating to IPH5201.
As a reminder, Orega Biotech claimed joint ownership of certain patents relating to IPH5201. The Company and Orega Biotech have resolved these claims in an arbitration proceeding, which decision was rendered in December 2021. As a result of this decision, the Company is required to pay a low-teen percentage of sub-licensing revenues received by the Company pursuant to its agreement with AstraZeneca regarding IPH5201. Following this arbitration decision, the Company paid in January 2022 an additional amount of €0.4 million to Orega. The Company announced on June 3, 2022 the progress of IPH5201 towards a study of Phase 2 in lung cancer, of which the Company will be a sponsor. In accordance with the amendment signed on June 1, 2022, the Company was eligible for a milestone payment of $5 million by AstraZeneca, received in August 2022 by the Company. In October 2022, the Company therefore paid an additional €0.6 million to Orega Biotech.
On June 26, 2023, the Company announced the treatment of the first patient in the Phase 2 MATISSE trial, conducted in collaboration with AstraZeneca and evaluating IPH5201 in early-stage lung cancer. As a consequence, the Company made an additional payment of €2.0 million to Orega Biotech in July 2023, in accordance with the agreement signed in 2019.
Avdoralimab (IPH5401) (anti-C5aR) rights acquired from Novo Nordisk A/S
At the agreement inception, an upfront payment of €40 million for acquired rights were recorded as intangible asset. As part of this agreement, an additional amount of €1.0 million was paid in October 2020 to Novo Nordisk A / S following the launch of the first avdoralimab Phase II trial. As avdoralimab is still in clinical trial, the acquired rights are classified as intangible asset in progress. They were subject to annual impairment test.
According to the agreement, the Company will pay additional payments according to the reach of specific steps. As of June 30, 2024, according to the uncertainty of these potential future payments, no liability was recognized.
Development costs incurred by the Company are recognized as research and development expenses.
As a reminder, during 2022 fourth quarter, the Company was informed by the sponsor of the Phase 2 clinical trial evaluating avdoralimab in inflammation in bullous pemphigoid ("BP") indication of its decision to discontinue said trial. Consequently, the Company decided in December 2022 to stop the development of avdoralimab in bullous pemphigoid ("BP") indication in inflammation, only indication supporting the recoverable amount of the asset as of December 31, 2021 (as well that as of June 30, 2022).
Following that decision, the Company applied IAS 36 "Impairment of assets" and assessed that there was an indication of impairment sufficiently significant to result in the full impairment of the intangible asset. This depreciation was recognized with regard to the estimate of the recoverable value of avdoralimab's intangible assets, based on expected future cash flows, as of December 2022, date of the decision. Thus, on decision date to stop the development of avdoralimab in bullous pemphigoid ("BP") indication in inflammation, avdoralimab rights were fully written down to their net book value, i.e €41,000 thousand.

Innate Pharma |Half-year financial report June 30, 2024 | 29




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.

11.Capital
11.1Share capital

The Company manages its capital to ensure that the Company will be able to continue as a going concern while maximizing the return to shareholders through the optimization of the debt and equity balance.
As of June 30, 2024, the Company’s share capital amounted to €4,049,075 divided into (i) 80,967,407 ordinary shares, each with a nominal value of €0.05; (ii) 6,509 “2016” preferred shares, each with a nominal value of €0.05, and (iii) 7,581 “2017” preferred shares, each with a nominal value of €0.05, respectively, fully paid up.
Share capital does not include BSAs, BSAAR, AGAs and AGAPs that have been granted to certain investors or natural persons, both employees and non-employees of the Company, but not yet exercised.
On October 21, 2019 and December 30, 2019, the retention period for the “2016 free preferred shares” has ended. The number of ordinary shares to which the conversion of one preferred share entitle has been determined according to the achievement of the performance criteria. Holders of “2016” preferred shares” are entitled to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on the basis of the number of ordinary shares to which they are entitled if they convert their preferred shares.
In April 3, 2021, the retention period for the "2017 free preferred shares" has ended. The number of ordinary shares to which the conversion of one preferred share entitle has been determined according to the fulfillment of the performance criteria. According to these same performance criteria, the Executive Board of April 7, 2021 noted that the "2017 preferred shares" did not give right to any ordinary shares. The “2017 preferred shares” will not be redeemed by the Company and will remain incorporated into the capital, unless subsequently decided by the Executive Board. As the conversion is void, the "2017 preferred shares" no longer give the right to vote at our general meetings, nor to receive dividends.
In the six months ended June 30, 2024, a capital increase of €5,342 occurred as a result of the Executive Board decision on June 10, 2024, subsequent to the creation of 106,844 ordinary shares following the set-up of a company saving plan for the benefit of the Company’s employees, including 68,744 ordinary shares issued free of charge (top-up). This event led to a net capital increase of €5,342 and an increase in share premium of €88,003, broken down as a creation of 38,100 ordinary shares, with a nominal value of €0.05, for an issue price of €2.45, (ii) a creation of 68,744 ordinary shares, with a nominal value of €0.05.

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, 2024 to June 30, 2024;
the verification of the information presented in the half-yearly management report.

These condensed half-yearly consolidated financial statements are the responsibility of the Executive Board. 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.

Company Information [Abstract]  
The Company and key events The Company and key eventsThe company
Innate Pharma SA (the “Company” and, with its subsidiary, referred to as the “Group”), is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. Its innovative approach aims to harness the innate immune system through therapeutic antibodies and its ANKET® (Antibody-based NK cell Engager Therapeutics) proprietary platform. Innate’s portfolio includes lead proprietary program lacutamab, developed in advanced form of cutaneous T cell lymphomas and peripheral T cell lymphomas, monalizumab developed with AstraZeneca in non-small cell lung cancer, as well as ANKET® multi-specific NK cell engagers to address multiple tumor types. 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 2024 generated a net loss of 24,764 thousand euros. As of June 30, 2024, shareholders' equity amounted to 28,796 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, 2024, the Company had one wholly owned subsidiary: Innate Pharma, Inc., incorporated under the laws of Delaware in 2009. The subsidiary is consolidated according global integration.
Innate Pharma is based in Marseille, France and listed on Euronext Paris and Nasdaq in the United States., and had 168 full time equivalent employees as of June 30, 2024.

On April 15, 2024, the Company announced the treatment of the first patient in the Phase 2 dose expansion part of the Sanofi-sponsored clinical trial evaluating NK Cell Engager SAR443579/ IPH6101 in various blood cancers.

Significant Accounting Policies [Abstract]  
Basis of presentation and statement of compliance Basis of presentation and statement of complianceBasis of preparation
The interim condensed consolidated financial statements as of June 30, 2024 and for the six-months period ended June 30, 2024 and 2023 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 loss-making 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 closed by the Executive Board, approved and authorized by the Supervisory Board on September 11, 2024 upon recommendation of the Audit Committee on September 10, 2024.
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.
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, 2023.
The results of the operations for the six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 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.
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 2.w) of the appendix to the consolidated financial statements as of December 31, 2023 filed with SEC (20-F) on April 2, 2024. As of June 30, 2024, the Company has not identified any other significant estimates and judgments that could have an impact on the consolidated financial statements.
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, 2024 and, as such, they have been adopted by the Company:
Amendments to IAS 1 : Classification of liabilities with covenants;
Amendments to IAS 7 and IFRS 7 : Supplier finance arrangements;
Amendments to IFRS 16 : Lease liability in a sale and leaseback.
Those amended standards have no impact on the interim condensed consolidated financial statements.
The Company has not opted for the early application of any standards whose application would be mandatory from subsequent financial years.

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.

The amount of €29,755 thousand recognized as current receivables as of December 31, 2023 comprises the research tax credit for the 2019 and 2020 tax years, for which the three year period has expired as of December 31, 2023. The CIR for 2019 was reimbursed in January 2024 for an amount of €16,737 thousand and to the CIR for the 2020 tax year of €13,018 thousand was collected in July 2024 for the amount of €12,755 thousand following the offset of the restated amount of €263 thousand (see note 8). The amount of €13,850 thousand recognized as a non-current receivable as of June 30, 2024 corresponds to the CIR for the 2023 tax year for the amount of €9,800 thousand and the amount of CIR calculated for the first half of 2024 for the amount of €4,050 thousand. Following the loss of SME status since December 31, 2023, the CIR for 2023 and 2024 represent non-current receivables from the French Treasury, which should in principle be offset against corporate income tax due for the following three years or refunded if necessary upon expiry of such a period.

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. For each period-end, an adjustment is made through the prepaid accounts to reflect the fact that the expenses are related to the fiscal year (see note 9).
(4) As of December 31, 2023, the amount is mainly comprised of invoice of €15,000 thousand issued in December 2023 following the exercise of the license option by Sanofi. This amount was collected by the Company in January 2024.

(1) This amount corresponds to the additional invoice received from Orega Biotech for the rights relating to IPH5201 following the first patient dosed in the Phase 2 MATISSE clinical trial in June 2023, in accordance to the agreement signed in 2019. This additional invoice is fully amortized as of June 30, 2023 and paid on July 2023.
(2) As of June 30, 2024, this amount included the amortization of rights related to the monalizumab for an amount of €294 thousand. As of June 30, 2023, this amount includes the amortization of the additional payment made to Orega Biotech in 2023 for and amount of €2,000 thousand and the amortization of rights related to the monalizumab for an amount of €651 thousand.

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 has reassessed the anticipated residual duration of the Phase 2 trials as of June 30, 2024 and estimated that it would be fully amortized by 2024, which is the same estimation as of December 31, 2023, as a result of the completion of some trials and by modifying the estimated end dates relating to certain cohorts.
The net book values of the monalizumab rights were €119 thousand and €416 thousand as of June 30, 2024 and December 31, 2023, respectively.
IPH5201 (Anti-CD39) rights acquired from Orega Biotech
On January 4, 2016, the Company and Orega Biotech entered into an exclusive licensing agreement by which Orega Biotech granted the Company full worldwide rights to its program of first-in-class anti-CD39 checkpoint inhibitors. The upfront payment paid by the Company to Orega Biotech has been recognized as an intangible asset in the consolidated financial statements for the year ended December 31, 2016. Criteria relating to the first development milestone were reached in December 2016. Consequently, the amount of this milestone was recognized as an intangible asset in addition to the initial payment. In June 2019, the Company also paid Orega Biotech €7.0 million in relation to the anti-CD39 program as consideration following the collaboration and option agreement signed on October 22, 2018 with AstraZeneca regarding IPH5201. Under this agreement, the Company also paid in April and
June 2020, respectively €2.5 and €0.2 million to Orega Biotech following the first Phase 1 dosing relating to IPH5201.
As a reminder, Orega Biotech claimed joint ownership of certain patents relating to IPH5201. The Company and Orega Biotech have resolved these claims in an arbitration proceeding, which decision was rendered in December 2021. As a result of this decision, the Company is required to pay a low-teen percentage of sub-licensing revenues received by the Company pursuant to its agreement with AstraZeneca regarding IPH5201. Following this arbitration decision, the Company paid in January 2022 an additional amount of €0.4 million to Orega. The Company announced on June 3, 2022 the progress of IPH5201 towards a study of Phase 2 in lung cancer, of which the Company will be a sponsor. In accordance with the amendment signed on June 1, 2022, the Company was eligible for a milestone payment of $5 million by AstraZeneca, received in August 2022 by the Company. In October 2022, the Company therefore paid an additional €0.6 million to Orega Biotech.
On June 26, 2023, the Company announced the treatment of the first patient in the Phase 2 MATISSE trial, conducted in collaboration with AstraZeneca and evaluating IPH5201 in early-stage lung cancer. As a consequence, the Company made an additional payment of €2.0 million to Orega Biotech in July 2023, in accordance with the agreement signed in 2019.
Avdoralimab (IPH5401) (anti-C5aR) rights acquired from Novo Nordisk A/S
At the agreement inception, an upfront payment of €40 million for acquired rights were recorded as intangible asset. As part of this agreement, an additional amount of €1.0 million was paid in October 2020 to Novo Nordisk A / S following the launch of the first avdoralimab Phase II trial. As avdoralimab is still in clinical trial, the acquired rights are classified as intangible asset in progress. They were subject to annual impairment test.
According to the agreement, the Company will pay additional payments according to the reach of specific steps. As of June 30, 2024, according to the uncertainty of these potential future payments, no liability was recognized.
Development costs incurred by the Company are recognized as research and development expenses.
As a reminder, during 2022 fourth quarter, the Company was informed by the sponsor of the Phase 2 clinical trial evaluating avdoralimab in inflammation in bullous pemphigoid ("BP") indication of its decision to discontinue said trial. Consequently, the Company decided in December 2022 to stop the development of avdoralimab in bullous pemphigoid ("BP") indication in inflammation, only indication supporting the recoverable amount of the asset as of December 31, 2021 (as well that as of June 30, 2022).
Following that decision, the Company applied IAS 36 "Impairment of assets" and assessed that there was an indication of impairment sufficiently significant to result in the full impairment of the intangible asset. This depreciation was recognized with regard to the estimate of the recoverable value of avdoralimab's intangible assets, based on expected future cash flows, as of December 2022, date of the decision. Thus, on decision date to stop the development of avdoralimab in bullous pemphigoid ("BP") indication in inflammation, avdoralimab rights were fully written down to their net book value, i.e €41,000 thousand.

(1) As a reminder, on January 5, 2022, the Company announced that it had obtained €28.7 million in non-dilutive financing in the form of two State Guaranteed Loans from Société Générale (€20.0 million) and BNP Paribas (€8.7 million). 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.
(2) On July 3, 2017, the Company borrowed from the Bank “Société Générale” in order to finance the construction of its future headquarters. 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 thousand.
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 system, development of a commercial platform, development of additional premises rented, etc.). As of June 30, 2024, the remaining capital of the loan amounted to €9,617 thousand. The Company authorized collateral over financial “Société Générale” instruments amounting to €15,200 thousand. 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 €4.2m financial instrument that had reached maturity, the company received this amount in July 2024.
This loan bears a fixed interest rate of 2.01%. It is subject to a covenant based on the assumption that the total cash, cash equivalents and current and non-current financial assets are at least equal to principal as of financial year end.
(3) As a reminder, on March 13, 2023, the Company signed an amendment to the lease for the "Le Virage" building, reducing the surface area of the leased premises. The effective date of the lease amendment is March 15, 2023. As a result, and in accordance with IFRS 16, the impact on the consolidated balance sheet at the effective date of the lease amendment is as follows: write-off of a right of use (asset) of €0.5 million and a lease liability of €0.7 million.

Share Capital and Share Base Payments [Abstract]  
Capital CapitalShare capital
The Company manages its capital to ensure that the Company will be able to continue as a going concern while maximizing the return to shareholders through the optimization of the debt and equity balance.
As of June 30, 2024, the Company’s share capital amounted to €4,049,075 divided into (i) 80,967,407 ordinary shares, each with a nominal value of €0.05; (ii) 6,509 “2016” preferred shares, each with a nominal value of €0.05, and (iii) 7,581 “2017” preferred shares, each with a nominal value of €0.05, respectively, fully paid up.
Share capital does not include BSAs, BSAAR, AGAs and AGAPs that have been granted to certain investors or natural persons, both employees and non-employees of the Company, but not yet exercised.
On October 21, 2019 and December 30, 2019, the retention period for the “2016 free preferred shares” has ended. The number of ordinary shares to which the conversion of one preferred share entitle has been determined according to the achievement of the performance criteria. Holders of “2016” preferred shares” are entitled to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on the basis of the number of ordinary shares to which they are entitled if they convert their preferred shares.
In April 3, 2021, the retention period for the "2017 free preferred shares" has ended. The number of ordinary shares to which the conversion of one preferred share entitle has been determined according to the fulfillment of the performance criteria. According to these same performance criteria, the Executive Board of April 7, 2021 noted that the "2017 preferred shares" did not give right to any ordinary shares. The “2017 preferred shares” will not be redeemed by the Company and will remain incorporated into the capital, unless subsequently decided by the Executive Board. As the conversion is void, the "2017 preferred shares" no longer give the right to vote at our general meetings, nor to receive dividends.
In the six months ended June 30, 2024, a capital increase of €5,342 occurred as a result of the Executive Board decision on June 10, 2024, subsequent to the creation of 106,844 ordinary shares following the set-up of a company saving plan for the benefit of the Company’s employees, including 68,744 ordinary shares issued free of charge (top-up). This event led to a net capital increase of €5,342 and an increase in share premium of €88,003, broken down as a creation of 38,100 ordinary shares, with a nominal value of €0.05, for an issue price of €2.45, (ii) a creation of 68,744 ordinary shares, with a nominal value of €0.05Treasury shares
The Company held 18,575 of its own shares as of June 30, 2024 and December 31, 2023, respectively.

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.
Use of judgments and estimates 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 2.w) of the appendix to the consolidated financial statements as of December 31, 2023 filed with SEC (20-F) on April 2, 2024. As of June 30, 2024, the Company has not identified any other significant estimates and judgments that could have an impact on the consolidated financial statements.
Recently issued accounting standards and interpretations 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, 2024 and, as such, they have been adopted by the Company:
Amendments to IAS 1 : Classification of liabilities with covenants;
Amendments to IAS 7 and IFRS 7 : Supplier finance arrangements;
Amendments to IFRS 16 : Lease liability in a sale and leaseback.
Those amended standards have no impact on the interim condensed consolidated financial statements.
The Company has not opted for the early application of any standards whose application would be mandatory from subsequent financial years.

(1) As a reminder, on January 5, 2022, the Company announced that it had obtained €28.7 million in non-dilutive financing in the form of two State Guaranteed Loans from Société Générale (€20.0 million) and BNP Paribas (€8.7 million). 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.
(2) On July 3, 2017, the Company borrowed from the Bank “Société Générale” in order to finance the construction of its future headquarters. 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 thousand.
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 system, development of a commercial platform, development of additional premises rented, etc.). As of June 30, 2024, the remaining capital of the loan amounted to €9,617 thousand. The Company authorized collateral over financial “Société Générale” instruments amounting to €15,200 thousand. 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 €4.2m financial instrument that had reached maturity, the company received this amount in July 2024.
This loan bears a fixed interest rate of 2.01%. It is subject to a covenant based on the assumption that the total cash, cash equivalents and current and non-current financial assets are at least equal to principal as of financial year end.
(3) As a reminder, on March 13, 2023, the Company signed an amendment to the lease for the "Le Virage" building, reducing the surface area of the leased premises. The effective date of the lease amendment is March 15, 2023. As a result, and in accordance with IFRS 16, the impact on the consolidated balance sheet at the effective date of the lease amendment is as follows: write-off of a right of use (asset) of €0.5 million and a lease liability of €0.7 million.
