* The Company complies with the Afep guidelines updated in February 2021. (1) The ratios are calculated on the basis of the compensation paid to the various Chief Executive Of fi cers during the period of their position, namely Philippe KNOCHE until October 3, 2023, Claude IMAUVEN from October 3 to November 15, 2023, and Nicolas MAES from November 15, 2023. (2) Not applicable because the Company has only one employee. (3) Given that Orano SA has few employees compared to the Orano group’s total workforce in France, in accordance with recommendation 27.2 of the Afep Medef Code, the “signi fi cant scope” used by Orano SA is the Orano group extending to the group’s French subsidiaries within the meaning of Article L. 233 16 II of the French Commercial Code. (4) The change in the Chief Executive Of fi cer’s compensation should be analyzed taking into account the payment in 2023 of a variable component solely in respect of the period from January 1 to April 28, 2022, and the differentiated compensation of successive Chief Executive Of fi cers during 2023. (5) The change in the compensation of the Chief Executive Of fi cer must be analyzed including the payment in 2025 of a variable compensation over a full year of service
