SUSTAINABILITY STATEMENT Social and societal information

Alleged cases of harassment, as well as sexist or discriminatory behavior, must be investigated in accordance with strict principles, including fair treatment of all parties involved, discretion in handling the situation, and anonymity of information disclosed to third parties. Following the investigation, Management reserves the right to initiate any disciplinary action. Each case is the subject of an action plan managed by the human resources teams and shared with the employee representative bodies if necessary. Orano Vox, a regular employee survey In 2017, Orano set up an annual employee engagement barometer called Orano Vox. The purpose of this approach is to assess employees’ engagement and their state of mind, to measure their understanding of the group’s issues and the corporate project, and to report on strengths and concerns.

The 2025 edition posted record participation of 79%. It con fi rmed the strengths: ● a safety culture that continues to progress; ● a resounding endorsement of actions in the areas of training, everyday respect, and CSR commitment; and ● a better understanding of the group’s strategy and the group’s challenges in terms of ef fi ciency. However, areas for improvement remain and will be among the group’s priorities in 2026: IT issues and tool performance, management of recruitment in a growth phase and organization between the group’s entities. The group monitors, among other things, the commitment rate, which corresponds to the proportion of employees who responded to the survey who would recommend Orano as an employer to their family or friends. The engagement rate (corresponding to the Net Promoter Score) was 67% for the 2025 campaign, up 5 points compared to 2024.
