Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) ("Innate" or the "Company") today reported its consolidated financial results for the year ending December 31, 2023. The consolidated financial statements are attached to this press release.
"We ended 2023 with a cash runway to the end of 2025 and achieved significant milestones in advancing our pipeline," said Hervé Brailly, Chief Executive Officer ad interim of Innate Pharma. "We reported positive data with lacutamab in Sézary syndrome, began Phase 1 testing of our proprietary, second-generation ANKET® IPH6501 and secured further validation of our ANKET® platform with Sanofi having licensed four ANKET® candidates for hematologic malignancies and solid tumors. The Phase 3 trial for monalizumab in non-small lung cancer that is being led by Astra Zeneca continues to advance. Looking ahead to 2024, we expect notable milestones including final results from the TELLOMAK Phase 2 trial with lacutamab in mycosis fungoides, and progressing our first proprietary ADC program, IPH45 towards an IND filing."

ANKET® is Innate's proprietary platform for developing next-generation, multi-specific NK cell engagers to treat certain types of cancer. Innate's pipeline includes five public drug candidates born from the ANKET® platform: SAR443579 (SAR'579/IPH6101) (CD123-targeted), SAR445514 (SAR'514/IPH6401) (BCMA-targeted), IPH62 (B7-H3-targeted), IPH67 (target

undisclosed, solid tumors) and tetra-specific IPH6501 (CD20-targeted with IL-2v). Several other undisclosed proprietary preclinical targets are being explored.
• The Phase 1/2 clinical trial with SAR'514 / IPH6401, a trifunctional anti-BCMA Nkp46xCD16 NK cell engager, led by Sanofi, in patients with Relapsed/Refractory Multiple Myeloma and Relapsed/Refractory Light-chain Amyloidosis is ongoing.
• As announced on December 19, 2022, Sanofi licensed IPH62, a NK cell engager program targeting B7-H3 from Innate's ANKET® platform. Upon candidate selection, Sanofi will be responsible for all development, manufacturing and commercialization. Under the terms of the research collaboration and license agreement signed in December 2022, Innate received a €25m upfront payment and is eligible for up to €1.35bn total in preclinical, clinical, regulatory and commercial milestones plus royalties on potential net sales.
• In December 2023, Sanofi exercised its option to license a NK cell engager program in solid tumors from Innate's ANKET® platform pursuant to the terms of the research collaboration and license agreement signed in December 2022. Following a research collaboration period, Sanofi will be responsible for all development, manufacturing and

commercialization. Sanofi still retains the option to one additional ANKET® target. Innate received a €15m payment as option exercise.
• The Phase 3 PACIFIC-9 trial run by AstraZeneca evaluating durvalumab (anti-PD-L1) in combination with monalizumab or AstraZeneca's oleclumab (anti-CD73) in patients with unresectable, Stage III non-small cell lung cancer (NSCLC) who have not progressed following definitive platinum-based concurrent chemoradiation therapy (CRT) is ongoing.
• The MATISSE Phase 2 clinical trial conducted by Innate in neoadjuvant lung cancer for IPH5201, an anti-CD39 blocking monoclonal antibody developed in collaboration with AstraZeneca, is ongoing and recruitment is on track.
• The investigator-sponsored CHANCES Phase 1 trial of IPH5301 by Institut Paoli-Calmettes is ongoing.
• Fueling its R&D pipeline, Innate continues to develop different approaches for the treatment of cancer utilizing its antibody engineering capabilities to deliver novel assets, with its innovative ANKET® platform and exploring Antibody Drug Conjugates (ADC) formats. Beyond its proprietary programs, Innate has an ongoing agreement with Takeda on ADCs.

• In April 2023, Innate 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. Under the terms of the license agreement, Innate received a \$5m upfront payment and is eligible to receive up to \$410m in future development, regulatory and commercial milestones if all milestones are achieved during the term of the agreement, plus royalties on potential net sales of any commercial product resulting from the license.

The key elements of Innate's financial position and financial results as of and for the year ended December 31, 2023 are as follows:

of December 31, 2023, and €1.7m for research work to be carried out by the Company as well as the recognition in revenue of an amount of €2.5m initially received in March 2023 in connection with this option;

mainly in the fields of personnel costs and depreciation, amortization and impairment.

The following table summarizes operating revenue for the periods under review:
| In thousands of euro | December 31, 2023 | December 31, 2022 |
|---|---|---|
| Revenue from collaboration and licensing agreements | 51,901 | 49,580 |
| Government financing for research expenditures | 9,729 | 8,035 |
| Other income | 11 | 59 |
| Revenue and other income | 61,641 | 57,674 |
Revenue from collaboration and licensing agreements from continuing operations increased by €2.3 million, to €51.9 million for the year ended December 31, 2023, as compared to €49.6 million for the year ended December 31, 2022. These revenues mainly result 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. The evolution in 2023 is mainly due to:

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 €25.0m in March 2023, including €18.5m for the exclusive license, €1.5m for the research work and €5.0m for the two additional targets options, for which the Company will recognize the related revenues either at the reporting date or three years after the effective date. The €18.5m upfront payment relating to the exclusive license has been fully recognized in revenue since June 30, 2023. On December 19, 2023, the Company announced that Sanofi had exercised one of the two license options for a new program based on the Company's ANKET® platform. This decision triggered a milestone payment of €15.0m, including €13.3m for the exclusive license, fully recognized in revenue as of December 31, 2023, and €1.7m for research work to be carried out by the Company. Following the notification of the exercise of the option, the Company also recognized in revenue an amount of €2.5m initially received in March 2023 and related to this option. The cumulative payments of €3.2m received for research work are recognized on a straight-line basis over the duration of the research work that the Company has agreed to carry out. As of December 31, 2023, the Company recognize in revenue an amount of €0.4 million based on the stage of completion of this work. The remaining amount of €2.8 million is recognized in deferred-revenue. Sanofi still retains a license option for an additional ANKET® target, in accordance with the license agreement. Consequently, the corresponding upfront payment is also recognized in deferred-revenue as of December 31, 2023 for an amount of €2.5m;

Government funding for research expenditures increased by €1.7 million, or 21.1%, to €9.7 million for the year ended December 31, 2023, as compared to €8.0 million for the year ended December 31, 2022. As of December 31, 2023, government funding is mainly comprised of research tax credit for for 2023 fiscal year for an amount of €9.8 million as compared to €7.9 million euros for year ended December 31, 2022. As a reminder, the 2022 research tax credit included a reduction of €1.3 million related to a provision following the tax inspection carried out in 2022 by the French tax authorities. This provision was based on estimated amounts and adjustments not disputed by the Company. The change in the research tax credit is due to an increase in eligible expenses explained by (i) the increase in depreciation on IPH5201 rights following the full amortization of the additional payment of €2.0 million to Orega Biotech following the dosing of the first patient in the MATISSE Phase 2 clinical trial, compared with €0.6 million as of December 31, 2022, and (ii) an increase in subcontracting expenses in connection with the IPH6501 program and the launch of work on the Lacutamab program. However, these increases are offset by the decrease in amortization of the monalizumab intangible asset due to the extension of the amortization period, as well as for certain tangible assets which had reached the end of their amortization period, and also by lower R&D personnel costs. The increase in expenses eligible for the research tax credit is also due to the absence of any grants received in 2023, which reduced the eligible base, as compared to 2022, when the eligible base was reduced by the receipt of the remaining repayable advance from the BPI for the amount of €0,7 million to support the independent Phase 2 clinical trial FOR COVID-19 Elimination (FORCE), evaluating the safety and efficacy of avdoralimab in patients with severe COVID-19 pneumonia.
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.
The table below presents our operating expenses from continuing operations for the years ended December 31, 2023 and 2022:
| In thousands of euros | December 31, 2023 | December 31, 2022 |
|---|---|---|
| Research and development expenses | (56,022) | (51,663) |
| Selling, general and administrative expenses | (18,288) | (22,436) |
| Operating expenses | (74,310) | (74,099) |
Research and development ("R&D") expenses from continuing operations increased by €4.4 million, or 8.4%, to €56.0 million for the year ended December 31, 2023, as compared to €51.7 million for the year ended December 31, 2022. This increase over the period is mainly due to an increase in direct research and development expenses of €2.7 million over the period due to the significant increase in expenses relating to pre-clinical development programs, partly offset by the decrease in expenses relating to clinical programs. Research and

development expenses represented a total of 75.4% and 69.7% of operating expenses for years ended December 31, 2023 and December 31, 2022, respectively.
Direct research and development expenses increased by €2.7 million, or 9.8%, to €30.2 million for the year ended December 31, 2023, as compared to direct research and development expenses of €27.5 million for the year ended December 31, 2022. This increase is mainly due to: (i) a €3.2 million increase in expenses related to preclinical development programs relating notably to Antibody Drug Conjugates - ADC field, partly offset by a €0.5 million decrease in expenses related to the Company's clinical programs. This decrease in clinical programs expenses mainly results from a €0.4 million decrease in expenses relating to the monalizumab program, a €0.2 million decrease in expenses relating to the avdoralimab program and a €0.2 million decrease in expenses relating to the lacutamab program, partly offset by a €0.7 million increase in expenses related to the growth in IPH5201 Phase 2 trials patient recruitment.
Also, as of December 31, 2023, the collaboration liabilities relating to monalizumab and the agreements signed with AstraZeneca in April 2015, October 2018 and September 2020 amounted to €52.7 million, as compared to collaborations liabilities of €63.2 million as of December 31, 2022. This decrease of €10.5m mainly results from (i) net repayment of €8.4 million during year 2023 to AstraZeneca linked to the Monalizumab cofinancing program, including Phase 3 trial INTERLINK-1 launched in October 2020 and PACIFIC-9 launched in April 2022, and (ii) the decrease of the collaboration commitment ("collaboration liabilities" in the consolidated statements of financial position) for an amount of €2.0 million linked to the Eurodollar parity exchange rate variation.
Personnel and other expenses allocated to research and development increased by €1.7 million, or 6.9%, to €25.8 million for the year ended December 31, 2023, as compared to an amount of €24.2 million for the year ended December 31, 2022. This increase is due to the (i) €0.7 million increase in staff costs allocated to research and development, of which €0.5 million in personnel expenses and €0.2 million in share-based payment expenses, (ii) increase of €1.0 million in depreciation and amortization. The line item is mainly composed of the amortization of the monalizumab, IPH5201 intangible assets.
General and administrative ("G&A") expenses from continuing operations decreased by €4.1 million, or 18.5% to €18.3 million for the year ended December 31, 2023 as compared to €22.4 million for the year ended December 31, 2022. G&A expenses represented a total of 24.6% and 30.3% of the total operating expenses for the years ended December 31, 2023 and 2022, respectively.
Personnel expenses, which include the compensation paid to our employees, decreased by €1.4 million, or 13.6%, to €8.8 million for the year ended December 31, 2023, as compared to personnel expenses of €10.2 million for the year ended December 31, 2022. This decrease mainly results from a decrease in wages of €1.2 million as well as a decrease of €0.2 million in share-based payment expenses mainly explained by the decrease of employees.
Non-scientific advisory and consulting expenses mostly consist of auditing, accounting, legal and hiring services. These expenses decreased by €1.3 million, or 31.5%, to €2.9 million for the year ended December 31, 2023, as compared to an amount of €4.2 million for the year

ended December 31, 2022. This decrease mainly results from operating efficiency measures, which led to a reduction in the number of new hires, and use of external communication and consulting services.
Other general and administrative expenses relate to intellectual property, depreciation and amortization and other general, administrative expenses. These expenses decreased by €1.4 million or 17.9% to €6.5 million for the year ended December 31, 2023, as compared to an amount of €8.0 million for the year ended December 31, 2022.
This decrease related notably to savings (reduction in office space) and a reclassification of R&D laboratory support costs (maintenance, depreciation of R&D equipment) for €1.0 million in R&D.
As a reminder, as of December 31, 2022, impairment of intangible assets was linked to the full depreciation of the avdoralimab intangible asset (anti-C5aR rights acquired from Novo/Nordisk A/S) for an amount of €41.0 million (non-cash expense) following Company's decision to stop the development of avdoralimab in bullous pemphigoid ("BP") indication in inflammation.
We recognized a net financial gain of €5.1 million for the year ended December 31, 2023, as compared to €0.5 million net financial loss for the year ended December 31, 2022. This change mainly results from interest income on financial investments (net gain of €2.5 million in 2023), the change in the fair value of certain financial instruments (net gain of €1.6 million in 2023 as compared to a net loss of €1.6 million in 2022) and a net foreign exchange gain of €0.9 million in 2023 as compared to a net foreign exchange gain of €0.8 million in 2022.
As a reminder, a Termination and Transition Agreement was negotiated and executed, effective as of June 30, 2021 further to the Company's decision to return the rights of Lumoxiti back to AstraZeneca. Consecutively, activities related to Lumoxiti are presented as discontinued operations since October 1, 2021. Thus, the net income from discontinued operations related to Lumoxiti are nil as of December 31, 2023 as compared to a net loss of €0.1 million as of December 31, 2022 corresponding to residual costs associated with the transfer of activities to AstraZeneca.

The net cash flow used over the year ended December 31, 2023 amounted to €13.6 million, compared to a net cash flow used of €19.5 million for the year ended December 31, 2022.
The net cash flow used during the period under review mainly results from the following:
• Net cash used from operating activities of €32.6 million, mainly explained by (i) the receipt of €25.0 million from Sanofi in March 2023 following the entry into force of the research collaboration and licensing agreement signed in December 2022 under which the Company granted Genzyme Corporation, a wholly-owned subsidiary of Sanofi ("Sanofi") an exclusive licence to Innate Pharma's B7H3 ANKET® program and options on two additional targets, (ii) the receipt in May 2023 of a payment of €4.6 million (\$5,0 million) received from Takeda following the conclusion of an exclusive licensing agreement under which Innate grants Takeda exclusive worldwide rights for the research and development of antibody conjugates (Antibodu Drug Conjugates - ADC), (iii) the receipt in July 2023 of €2.0 million following the treatment of the first patient in the Phase 1/2 clinical trial sponsored by Sanofi evaluating IPH6401/SAR'514 in patients with relapsed or refractory multiple myeloma. Lastly, (iv) during 2023, the Company benefited from the early repayment of the research tax credit claim relating to the 2022 financial year, amounting to €9.2 million, paid to the Company by the French Treasury in July 2023. As a reminder, cash flows used in operating activities for the year ended December 31, 2022, included successive (i) the collection of €47.7 million (\$50.0 million) and €4.6 million (\$5.0 million) in June 2022 and August 2022,respectively, under the monalizumab agreement and the amendment to the IPH5201 collaboration and option agreement, (ii) the collection of €3.0 million received from Sanofi under the 2016 agreement and following Sanofi's decision to advance IPH6401/SAR'514 into regulatory preclinical studies for an investigational new drug, and (iii) in 2022, the Company collected the early repayment of the research tax credit receivable relating to the 2021 financial year for an amount of €10.3 million, paid to the Company by the French Treasury in November 2022. These collections were partially offset by the €5.9 million payment to AstraZeneca on April 20, 2022 pursuant to the Lumoxiti
termination and transition agreement and cash outflows related to the Company's operating activities. Not considering these specific effects , net cash flows used by operating activities for the year ended December, 2023 decreased by €5.5 million. This decrease is mainly explained by the decrease in the Company's research and development activities, notably related to preclinical trials, and also by higher cash outflows related to the re-invoicing of costs to AstraZeneca for the Phase 3 trials evaluating monalizumab, INTERLINK-1 and PACIFIC-9, in accordance with the Company's co-financing commitments and the reduction in staff costs related to the reduction of staff in the Company. Also, net cash flow consumed by operating activities in connection with the Lumoxiti discontinued operation are nil for the year ended December 31, 2023 as compared to € 5.1 million for the year 2022. In 2022, the cash consumption related to the payment to AstraZeneca of €5.9 million in April 2022 under the termination and transition agreement for Lumoxiti.
