Annual Activity Report 2025

Orano - Annual Activity Report 2025 347 FINANCIAL STATEMENTS 6 Consolidated financial statements – financial year ended December 31, 2025 Back end In the Back End segment, goodwill is carried by the Recycling BU in the amount of 171 million euros, the Nuclear Packages and Services BU in the amount of 68 million euros, the Dismantling and Services BU in the amount of 15 million euros and the Orano Projets BU in the amount of 6 million euros. The values in use calculated to carry out the impairment tests are obtained by discounting the projected future cash flows at a rate of between 7.75% and 8.75% (up +0.25% or stable depending on the BU, compared to those of December 31, 2024). The sensitivity analyses carried out show that the use of discount rates that are 50 basis points higher and/or standard-year growth rates that are 50 basis points lower would not have led to the recognition of any impairment of goodwill.
