ORANO // Annual Activity Report 2024

SUSTAINABILITY STATEMENT

Societal and environmental challenges at the heart of the strategy

Certain subsidiaries are excluded from the scope of consolidation if their contribution is marginal (less than 2%). The group documents these exclusions and ensures that they do not impact the fairness of the results presented. In accordance with EFRAG’s recommendations, however, this reporting scope may vary according to the various ESRS standards. The group has decided to apply principles that differ

from these requirements in order to promote consistency with market practices based on operational control and the consistency of the information provided in previous fi nancial years. The table below speci fi es the consolidation principles used in this respect according to the various indicators as well as the integration rates of the quantitative data relating to these indicators.

Indeed, this requires that joint operations be considered within the value chain on E3, E5 and G1. Consolidation for the 2024 fi nancial year was carried out on the basis of the operational control rule applied until the entry into force of the new directive. This choice is penalizing in terms of results for the group but consistent with the results of previous years. ** Group’s choice concerning indicators not required by an ESRS standard, known as “entity speci fi c”.

The group noted the loss of control of three Niger-based companies as of December 2024 (1) : Somaïr, Cominak and Imouraren. They were fi nancially deconsolidated as of November 30, 2024. With regard to sustainability information, the group applied the following rules: integration into the 2024 results until the end of November for activity indicators, deletion for indicators as of December 31, 2024, as well as in the targets. The group did not integrate any new companies in 2024. In the 2024 fi nancial year, none of the group’s subsidiaries was subject on its own to the directive. 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 so called “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).

Speci fi c information relating to intellectual property, know-how or the results of innovations Among the sustainability information required by the standard, the group considers con fi dential: information relating to the operating permit for the Katco mining site (including the operating area required by ESRS E4 - Section 4.2.3.1), as well as details of the serious human rights violation mentioned in Section 4.3.1.6. Partial or missing data points not related to phase-in arrangements Although Orano has implemented a risk management process related to the sustainability information (see Section 4.1.2.5), internal consolidation processes will be strengthened over time. The group will continue 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. As of December 31, 2024, some metrics are not or partially disclosed. Explanations are given at the level of each topical section.
