GOVERNANCE OF THE COMPANY AND GENERAL INFORMATION Administration and management of the Company

Secretary of the Board Christelle LE CALVEZ served as Secretary of the Board of directors until January 31, 2026. Marielle SALERA-CORDIER has served in this position since February 1, 2026. 5.1.1.4 Independence of the members of the Board of directors The Afep-Medef Code (Article 10.3) recommends that in controlled companies, within the meaning of Article L. 233-3 of the French Commercial Code, at least one-third of all Board members should be independent and speci fi es that those directors representing employees are not counted in establishing this proportion. As of the date of this report, the Board of directors has four independent members out of a total of eleven members (excluding directors representing employees). As recommended by the Afep Medef Code, at least one-third of the members are independent. Based on a recommendation made by the compensation and nominating committee on February 11, 2026, the Board of directors, at its meeting of February 19, 2026, considered the following Board members to be independent as per the criteria of the Afep-Medef Code: ● Claude IMAUVEN; The Board of directors meeting of February 19, 2026 reviewed the independence of the Company’s directors with regard to all the criteria set out in the Afep-Medef Code by referring to a statement questionnaire completed by each director. In particular, the Board of directors examined any business relationships that may exist between the Company and the companies in which these directors hold of fi ces and noted that none of the independent members has any signi fi cant business relationships with the Company. The primary basis for this assessment is the insigni fi cant share of revenue generated by existing business relationships, if any, compared to the respective revenue of the Company and the companies in which the members concerned hold a position. The table below shows the situation of each director at December 31, 2025 with regard to the independence criteria set out in Article 10 of the Afep-Medef Code. ● Anne-Sophie LE LAY; ● Patrick PELATA; and ● Marie-Hélène SARTORIUS.
