SUSTAINABILITY STATEMENT Social and societal information

The group does not directly solicit the workers in its value chain. In terms of workplace safety, the group interacts with the employees of external companies involved in its operations in order to ensure the consistent treatment in terms of prevention described in Section 4.3.1.2 Aiming for the highest standards in Health – Occupational Safety – Radiation protection .

The group’s whistleblowing mechanism, which allows any individual to submit a complaint, and how to access it, are described in Section 4.4.1.3. The group has not currently assessed the level of knowledge or trust of its suppliers with regard to its whistleblowing mechanism.

4.3.3 Being engaged and responsible locally in the regions where Orano operates [S3]

4.3.3.1 IROs related to affected communities As a long-term player in the regions where it operates, the group is vigilant about the impacts of its activities on the communities surrounding its facilities. Orano ensures their health and safety, their proper information and the sharing of value. The group includes affected communities such as: ● local residents living around the group’s operations and their representatives (elected of fi cials, associations, etc .); and ● the operating regions and, in particular, the economic fabric on which the operations depend (suppliers and subcontractors, local-development employment players).

For its materiality analysis and the identi fi cation of Impacts, Risks and Opportunities (IRO), Orano relied on its existing mapping (risks, vigilance), the knowledge of its experts, and existing studies (impact studies, speci fi c studies, etc .), as well as interviews with 150 stakeholders, as described in Section 4.1.5.2 Double materiality analysis methodology. For the analysis of the affected communities, the group relied heavily on interviews conducted in its regions of operation. The issue of indigenous peoples’ rights is not material (for more information, see Section 4.1.5.4).

SAFETY AND SECURITY OF OUR ACTIVITIES AND PRODUCTS (HEALTH AND SAFETY OF LOCAL RESIDENTS) [S3] POTENTIAL NEGATIVE IMPACT IMPACT ON PEOPLE OR THE ENVIRONMENT OF A NUCLEAR OR CHEMICAL ACCIDENT ON A FACILITY OR IN TRANSPORT OWN OPERATIONS, DOWNSTREAM

Orano’s operations, as part of its activities, may generate accidents at a facility or in transport (rail, maritime, road) with potential health and environmental consequences on local populations (chemical or radiological). A major accident would trigger the crisis management system to manage the emergency situation relating to the safety and health of employees and local residents, the environment and the safety of the facilities. Nuclear and industrial safety and security remain Orano’s priorities. POTENTIAL NUCLEAR SAFETY IMPACT ON A CUSTOMER GENERATED BY A QUALITY DEFECT ON A PRODUCT

A quality defect in a product can generate a safety risk for our customers.

A safety risk for an electricity supplier caused by a defective product made by Orano could lead to the occasional suspension of production at the site in question. The consequence would be a loss of revenue and cash flow.
