Annual Activity Report 2025

Orano - Annual Activity Report 2025 221 SUSTAINABILITY STATEMENT 4 Social and societal information The group monitors the accidents of contractors working on these facilities and takes necessary feedback to adapt practices. The group incorporates criteria relating to safety at work in the information requested from suppliers, in the qualification of the supplier and in the evaluation of calls for proposals, including the supply of goods produced on the premises of the third-party company. Prevention of the rights of employees of suppliers working on their own premises Since 2024, Orano has systematically mapped its health, safety, and environmental risks in relation to human rights. Based on an external framework, the group has identified two countries and eleven at-risk purchasing segments, particularly in terms of human rights. In particular, the mapping has been adapted to the scope and updated between 2024 and 2025 due to the loss of operational control of two operational entities in Niger (1) . In 2025, this represents 22 suppliers in Asia with which the group has an established commercial relationship, and on which additional checks will be carried out to ensure the absence of risks for workers and the environment. This verification program will continue in 2026. In terms of forced labor and child labor, the Code of Ethics affirms Orano’s commitment to promote and respect international human rights law. It explicitly prohibits the use of any form of human trafficking, forced or compulsory labor, as well as child labor. The group requires its business partners to contractually commit to excluding all practices related to child labor and forced labor. When it comes to granting access to the group’s sites, a procedure for verifying identity documents is put in place. This procedure aims to ensure that only authorized persons who comply with the age requirements can access the sites. Orano complies with local legislation on working time. In this respect, the group ensures that any additional work is carried out in compliance with local laws and is properly compensated. To this end, scheduling control procedures (tagging and/or reporting system) have been put in place to ensure the traceability of hours worked and to guarantee appropriate compensation for overtime hours worked. Orano ensures that all of its employees and subcontractors are housed in decent conditions on its mining sites. The group has defined strict health standards in terms of hygiene, access to drinking water and ventilation and carries out regular inspections by dedicated teams to verify compliance. The results of these inspections are taken into account to implement continuous improvements. Orano also organizes consultations with workers housed at its mining sites in order to identify potential problems and implement appropriate solutions. As a socially responsible and committed company, Orano attaches particular importance to the development of an inclusive policy, promoting gender balance, cultural and professional diversity and is actively committed to combating all forms of discrimination and harassment. The group also ensures that these values, included in its Code of Ethics, are applied to all its suppliers and subcontractors. The group operates in certain countries where the legal, economic and cultural context could potentially expose employees to violations of their social rights. These abuses may result in retaliation against employees involved in labor union activities or the deprivation of their right to collective bargaining. Furthermore, and in accordance with the terms of its Code of Ethics, Orano expects its suppliers to offer their employees freedom of association and the right to collective bargaining. 4.3.2.3 Targets and results related to workers in the value chain As part of its new Responsible Purchasing policy, the group’s objective is to have audited by 2030 100% of suppliers identified as presenting a risk of serious harm to the environment, health and safety or human rights. In 2025, 11 suppliers were subject to a specific review on these issues, out of the 22 identified by the Vigilance screening methodology. These reviews did not reveal any serious violations. The group was not aware in 2025 of any human rights violations in its value chain. As part of its HSE policy, Orano aims for a uniform level of prevention between employees and external companies in terms of health and safety at work. It has not set any target figures for results in this area. The results in terms of safety at work for external companies are detailed in Section 4.3.1.2. 4.3.2.4 Process for engaging with workers in the value chain Orano maintains relationships with its subcontractors and suppliers through business reviews at least once a year, questionnaires or surveys. The group regularly participates in GIFEN’s “IDYLL” barometer. In 2024, the group surveyed 170 suppliers through a questionnaire on their ESG practices. This mode of interaction has led to a better understanding of suppliers’ commitments on climate and other environmental issues. It will be renewed in 2026. The group also captures concerns through discussions within the professional associations in which it participates. The group’s Supply Chain transformation plan includes a component of discussions with a panel of key suppliers in order to simplify and make our collaboration processes more efficient.
