Selected financial information for the first half of fiscal year 2025-2026

Key consolidated figures - IFRS (in thousands of €)

The consolidated summary half-year financial statements in accordance with IFRS as of September 30, 2025 were approved by the Board of Directors on December 8, 2025. These financial statements have been subject to a limited review by the Statutory Auditors.

INCOME STATEMENT	September 30, 2025 6 months	September 30, 2024 6 months
Revenues	11 608	8 620
Other income	2 539	815
Current operating result	(6 612)	(7 598)
Operating result	(6 612)	(7 529)
Financial result	(9 459)	(6 910)
Net result	(16 078)	(14 568)

Total income (revenues and other income) up by 50%: €14.1 million

Revenues for the first half of the 2025-2026 financial year were 35% higher than in the same period last year, mainly driven by the following components:

• → Royalties on net sales from UZEDY® invoiced to Teva for a total of €4.2 million (vs €2.8 million year-on-year, a 50% increase) reflecting the strong momentum of UZEDY® which is partially offset by the weakness of USD vs EUR over the period.
• → Other partnerships revenues represented €7.3 million (vs €5.5 million in the first half of the previous year):
• o Revenues from the 1st program in development under the AbbVie collaboration accounted for €4.9 million,
• o Revenues from the Gates Foundation to develop a contraceptive long-acting injectable accounted for €1.4 million,
• o Revenues from other collaborations and from proof-of-feasibility studies accounted for €1.0 million.

Other income consisted mainly of the Research Tax Credit for €2.5 million.

Operating expenses up by 22%: €20.8 million

The increase in operating expenses is primarily related to R&D, which accounts for nearly 64% of total spending. The increase is mainly driven by the maturity of the portfolio, with more late-stage assets. The Company has also decided to accelerate certain activities related to technological innovation, to further extend its capabilities in terms of formulation.

Operating result: €(6.6) million, a 13% year-over-year improvement

Operating result is improving despite the unfavorable impact of the weak US dollar against the euro. The Company indicates that if the weakness of US dollar vs euro persists, operational profitability might occur later than the fiscal year 2026-2027.

Financial result impacted by the non-cash fair value adjustment of EIB warrants: €(9.5) million

The net financial loss increased from €6.9 million to €9.5 million over one year. This change is mainly due to a €6.8 million accounting revaluation with no cash impact related to the fair value of the BSA warrants allocated to the EIB, a direct consequence of the sharp rise in the Company's share price over the period (+65% from €14.4 on March 31, 2025 to €23.8 on September 30, 2025). Discussions are progressing with the EIB regarding a potential waiver of the put option clause allowing for cash repayment upon the occurrence of certain events.

The financial result was also impacted by financial exchange losses totaling €1 million, due to the unfavorable movement in the EUR/USD exchange rate, that affected cash held in USD.

^(*) The opening balance does not include €12.9 million of low-risk, short-term financial investments.

A- Net cashflow from operating activities

The change in net cash flow generated by operations is attributable to the receipt of the initial upfront payment from AbbVie (\$35 million) as well as the receipt of UZEDY® royalties and the payment from Unitaid in the first half of the 2024-2025 financial year. During this half-year period, only UZEDY® royalties were received, as well as payments relating to feasibility studies.

B- Net cashflow from investing activities

Net cash flow from investing activities is mainly explained by the change in financial investments over the period. For the halfyear ended September 30, 2024, €7.2 million was invested in these financial investments, while for the half-year ended September 30, 2025, €9.1 million was divested to meet the Company's operational needs. These financial investments of €3.7 million consist exclusively of short-term deposits with high liquidity and no risk of capital loss. They can be easily mobilized if necessary and generate additional financial income.

C- Net cashflow from financing activities

^(**) The closing balance does not include €3.7 million of low-risk, short-term financial investments.

The net cash flow from financing activities in the first half of the year ended September 30, 2025, was mainly due to the repayment of financial debt and lease liabilities (total disbursements of €2.7 million), as in the first half of the previous financial year (€2.4 million).
