Making use of the delegation of authority granted to him by the Board of Directors on June 11, 2025, itself acting under the 12th resolution approved by the General Meeting of Shareholders on June 10, 2025, the Company's Chief Executive Officer decided on July 21, 2025, to carry out a capital increase for a total amount of €1,580,603.41 (including share premium), through the issuance of 385,150 new ordinary shares at an average subscription price of €4.1039 per share.

On July 21, 2025, the Company combined into a single capital increase the subscription requests received from TOBAM between July 14 and July 18, 2025, and the subscription price has been determined in accordance with the terms of the ATM Agreement signed on June 6, 2025, namely:

• The price for each request is equal to the highest of (i) the closing price on the trading day preceding the request, (ii) the volume-weighted average price (VWAP) on the trading day preceding the request, or (iii) the average of the VWAP of the 20 last trading days preceding the request discounted by 15%; and
