Financial highlights for the first half of 2023:

The key elements of Innate’s financial position and financial results as of and for the six-month period ended June 30, 2023 are as follows:

• Cash, cash equivalents, short-term investments and financial assets amounting to €124.7 million (€m) as of June 30, 2023 (€136.6m as of December 31, 2022).
• Revenue and other income from continuing operations amounted to €40.2m in the first half of 2023 (€45.6m in the first half of 2022) and mainly comprise of:
  • Revenue from collaboration and licensing agreements, which mainly resulted from the partial or entire recognition of the proceeds received pursuant to the agreements with AstraZeneca, Sanofi and Takeda. They results from the partial or entire recognition of the proceeds received pursuant to the agreements with AstraZeneca, Sanofi and Takeda. They are recognized when the entity's performance obligation is met. Their accounting is made 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:
    • (i) Revenue from collaboration and licensing agreements for monalizumab decreased by €6.9m to €9.5m in the first half of 2023 (€16.4m in the first half of 2022). This change mainly results from the transaction price increase of €13.4 million ($14.0 million) in the first half of 2022, triggered by the launch of the “PACIFIC-9” Phase 3 trial on April 28, 2022. As a reminder, this increase in the transaction price led to the recognition of an additional revenue of €12.5 million for the first half of 2022. However, this decrease is partially offset by an increase in monalizumab-related revenues for the first half of 2023, in line with the progress of Phase 1/2 trials over the period.
    • (ii) Revenue related to the license and collaboration agreement signed with Sanofi in 2016 decreased by €1.0m, to €2.0m for the six months ended June 30, 2023, as compared to €3.0m for the six months ended June 30, 2022. The Company announced that, in June 2023, the first patient was dosed in a Sanofi-sponsored Phase 1/2 clinical trial evaluating SAR'514/IPH6401 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. As a reminder, the revenue recognized in the first half of 2022 resulted from Sanofi's decision to advance SAR'514/IPH6401 into investigational new drug (IND)-enabling studies. As such, Sanofi had selected a second multispecific antibody engaging NK cells as a drug candidate. This selection triggered a €3.0 million milestone payment from Sanofi to the Company, fully recognized in revenue as of June 30, 2022.
    • (iii) Revenue of €18.7 million related to the research collaboration and licensing agreement signed with Sanofi in 2022. 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 work and €5.0 million for the two additional targets options. The €18.5 million upfront payment relating to the exclusive license has been fully recognized in revenue as of June 30, 2023. The €1.5 million upfront payment will be recognized on a straight-line basis over the duration of the research work that the Company has agreed to carry out. The €5.0 million initial payment relating to the options is recognized in deferred revenue—non-current portion as of June 30, 2023. The Company will recognize the related revenues either at the reporting date or three years after the effective date.
    • (iv) Revenue of €4.6m related to the licensing agreement signed with Takeda in 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.
  • Government funding for research expenditures of €4.9m in the first half of 2023 (€4.3m in the first half of 2022).

• Operating expenses from continuing operations are €40.6m in the first half of 2023 (€37.1m in the first half of 2022), of which 77.5% (€31.5m) are related to R&D.
  • R&D expenses from continuing operations increased by €6.5m to €31.5m in the first half of 2023 (€25.0m in the first half of 2022). This change mainly results from (i) a €4.9m increase in direct R&D expenses relating to €4.8m non-clinical program in the Antibody Drug Conjugates (ADC) field and a slight increase of clinical programs of €0.1m; (ii) Personnel expenses and other R&D expenses increased by €1.6m (12.9%) to reach €14.2m in the first half 2023 compared to €12.6m in the first half 2022. This increase is mainly explained by €2.0m amortization for the rights relating to IPH5201 following the first patient dosed in the Phase 2 MATISSE clinical trial. The amortization of rights related to the monalizumab decreased by €0.3m.
  • General and administrative (G&A) expenses from continuing operations decreased by €3.0m to €9.1m in the first half of 2023 (€12.1m in the first half of 2022) mainly resulting from ((i) a €1.4m decrease of personnel expenses mainly due to a reduction of administrative workforce, (ii) a €0.6m decrease on non-scientific advisory and consulting fees (limited use of recruitment agencies and strategic consulting), and finally (iii) a decrease on other expenses for €1.0m mainly related to a decrease on leasing and maintenance for €0.5m to the benefit of research and development enabling a more consistent allocation of support expenses to the company's research laboratory as well as a reduction of 0.2 million following more limited use of external communication and investor relations service providers.
• Net income from discontinued operations related to Lumoxiti are nil compared to a net loss of €0.1 million for the first half of 2022 corresponding to residual costs associated with the transfer of activities to AstraZeneca. This transfer has now been completed.
• A net financial gain of €2.1m in the first half of 2023 (net financial loss of €2.1m in the first half of 2022), principally as a result of the increase in fair value of certain of our financial instruments and net foreign exchange gain over the period.
• A net income of €1.7m for the first half of 2023 (net income of €6.3m for the first half of 2022).
