Orano - Annual Activity Report 2025 122 4 SUSTAINABILITY STATEMENT Societal and environmental challenges at the heart of the strategy The impacts of these non-material differences are explained in the corresponding Sections (E3 and E5). The same rule has been applied by the group to the so-called “Entity specific” indicators. The group deconsolidated its Uzbek subsidiary, Nurlikum Mining, at September 30, 2025, following the change in the capital structure and the transfer of operational control to the partner Navoiyuran. With regard to sustainability information, the group applied the following rules: integration into the 2025 results until the end of September for activity indicators, deletion for indicators at December 31, 2025, as well as in the targets. In the 2025 financial year, none of the group’s subsidiaries was subject to the directive on its own. Coverage of the value chain The upstream and downstream value chains are covered in the materiality analysis. When exclusions are made on certain types of activities or stakeholders, this is mentioned at the beginning of each topical Section (example: employees of the downstream value chain excluded from the materiality analysis on the topic of “workers in the value chain”). In terms of indicators, the upstream and downstream value chains are only covered in greenhouse gas emissions (through the socalled ‘scope 3’ emissions required by ESRS E1). Employees in the upstream value chain working on Orano sites are covered by occupational safety indicators (ESRS S1). Specific information on confidentiality Among the sustainability information required by the standard, information relating to the operating license for the Katco mining site (whose operating area is required by ESRS E4 – Section 4.2.3.1) is confidential data. Partial or missing data points not related to phase-in arrangements Although Orano has implemented a risk management process related to the sustainability statement (see Section 4.1.2.5), internal consolidation processes will be strengthened over time to improve the reliability and coverage of certain indicators over the coming years and to implement new processes to collect information not available to date, in proportion to the materiality of the topics. The group made progress on the publication of indicators not disclosed or partially disclosed during the 2024 financial year, which are now disclosed on a group scope, namely: ● percentage of recyclable content in products and packaging (E5-5>36c); ● change in stored water (E3-4>28d); and ● total amount of fines, penalties and compensation for damages resulting from incidents and complaints related to discrimination (S1-17>103 c). The group’s actions in 2025 helped to improve the coverage rate of two indicators deemed too partial in 2024, namely: ● the total annual compensation ratio (unweighted average) (S116>97 b); and ● the gender pay gap (%) (S1-16>97a). At December 31, 2025, the group had not published the metrics required by the standard in terms of deaths related to occupational illnesses for employees and external companies (S1-14>88 b and S1-14>88 e). The group is working to publish these indicators on a worldwide basis in parallel with that of the number of occupational diseases (S1-14>88 d) as planned in 2027. The group also partially publishes the indicators Total annual compensation ratio (unweighted average) (S1-16 > 97b) and Gender pay gap (unweighted average) (S1-16 > 97a), out of a scope of 76% (vs. 71% in 2024). The coverage rate increased between 2024 and 2025 but still needs to be consolidated, particularly for entities outside of the centralized payroll system. For more information, see methodology information in Section 4.3.1 Mobilizing proud and committed employees who embody our corporate purpose. 4.1.1.2 Disclosure in relation to specific circumstances Time horizons The group uses the following time horizons: short-term (1 year), medium-term (3 years), long-term (5 years). Some IROs were assessed beyond a 5-year period. The physical risks associated with climate change are assessed at a minimum until 2050 and sometimes until 2100. Sources of uncertainty in value chain estimates and results The vast majority of sustainability indicators in this statement are based on actual data at year-end and without assumptions. The main indicators estimated are: ● scope 3 greenhouse gas emissions are by nature subject to a great deal of uncertainty due to the complexity of the various items, as well as the methodological assumptions used; ● the indicators relating to the quantities of MLW-LL and HLW radioactive waste produced in France in 2025 are estimated on the basis of data for 2024 and a similar activity between the two years; ● the hours worked for the calculation of the lost-time accident frequency rate are estimated on the basis of FTEs; ● certain water-related indicators (recycled, reused, or stored water) are estimated; and ● the share of recycled content in products and packaging.
