Daix (France), New York City (New York, United States), July 30, 2026 – Update to Press Release Dated July 29, 2026. The Company wishes to correct an error in the press release issued on July 29, 2026. On page 2, the potential proceeds for the Tranche C of the Debt Financing Transaction was mistakenly stated as €20 million. The correct figure is €55 million. All other information in the press release remains unchanged. As a result, the corrected version shall read as follows:

Inventiva (Euronext Paris and NASDAQ:IVA) ("Inventiva" or the "Company"), a clinical-stage biopharmaceutical company focused on the development of an oral therapy for the treatment of metabolic dysfunction-associated steatohepatitis ("MASH"), today reported certain preliminary financial results for the first half of 2026, including its cash, cash equivalents and revenues.

Preliminary Financial Results

As at June 30, 2026, the Company’s cash and cash equivalents amounted to €166.1 million and €67.8 million in short-term deposits², compared to cash and cash equivalents at €99.3 million and €131.6 million in short-term deposits as at December 31, 2025.

Net cash used in operating activities amounted to (€48.7) million for the first half of 2026, compared to (€53.7) million for the same period in 2025. The lower cash consumption mainly reflects the working capital change of €8.8 million between the two periods. This lower cash consumption is partially offset by the increase in operating expenses relating to the continued advancement of the NATiV3 Phase 3 clinical trial and preparation of pre commercial activities. R&D expenses amounted to (€50.1) million in the first half of 2026 compared to (€44.9) for the same period in 2025.

Net cash generated from investing activities for the first half of 2026 amounted to €63.9 million, compared to (€24.8) million for the first half of 2025. The increase is mostly due to new short-term deposit subscriptions following the June combined financing operations announced on June 2, 2026³.

Net cash generated from financing activities for the first half of 2026 amounted to €50.9 million, compared to €104.8 million in the first half of 2025.

The net cash generated from financing activities in the first half of 2026 reflects the comprehensive capital structure optimization announced on June 2, 2026, including the Equity Offering of €103 million and the Debt Financing Transaction of €75 million⁴. These cash inflows were partially offset by the repayment in full of the existing EIB loan for an aggregate amount of €62 million, and the repurchase of the Legacy EIB Tranche A Warrants and 700,000 of the Legacy EIB Tranche B Warrants for an aggregate repurchase price of €50 million. For further information regarding these transactions, please refer to the Company’s press releases dated June 2, 2026 and June 12, 2026.

The net cash generated from financing activities in the first half of 2025 came from the gross proceeds of €115.6 million (net proceeds of €108.0 million) from the second tranche of the Structured Financing announced in October 2024⁵.

Based on the Company’s existing cash and cash equivalents and short-term deposits, together with the net proceeds from the completed Equity Offering, the completed EIB Transactions and the issuance of Tranches A and B under the Debt Financing Transaction⁶, the Company expects to be able to finance its operations as currently planned until the end of the second quarter of 2027. At the date of this communication, the Company's current cash and cash equivalents are not sufficient to cover operating needs as currently planned for the next 12 months.

Based on the Company’s existing cash and cash equivalents and short-term deposits, together with the net proceeds from the completed Equity Offering, the completed EIB Transactions and the issuance of Tranches A and B under the Debt Financing Transaction, and assuming the successful completion of Tranche C of the Debt Financing Transaction for potential proceeds of up to €55.0 million and the exercise in full of the Tranche 3 warrants previously issued by the Company in the Structured Financing⁴ for potential proceeds of up to €116.0 million, the Company expects to be able to finance its operations as currently planned until the start of the first quarter of 2028⁷.

Over the first half of 2026, the Company recorded a positive foreign exchange effect on cash and cash equivalents of €0.7 million, compared with a negative effect of (€0.7) million for the first half of 2025, primarily due to the changes in the EUR/USD exchange rate.

Revenues

No revenues recorded for the first half of 2026, compared to €4.5 million generated for the same period in 2025.
