Annual Activity Report 2025

Orano - Annual Activity Report 2025 230 4 SUSTAINABILITY STATEMENT Social and societal information Dialogue mechanisms around our mining sites In each country where Orano Mining operates, information, dialogue, and consultation bodies are systematically set up and coordinated around the sites, in particular in the form of LICs (Local Information Commissions), SMCs (Site Monitoring Commissions), and visits. In France, a CartOmines web application provides the public with information on the monitoring of redeveloped former mining sites. Two websites have also been created to inform the public about the remediation projects of the former Bois-Noirs Limouzat and Bauzot mining sites. In 2025, more than 75 local information and mobilization commissions were held particularly in Canada, Mongolia, Uzbekistan, Kazakhstan, and France. In Canada, information meetings are regularly organized for local residents. These meetings provide an opportunity to update the activity of the McClean Lake plant, current exploration projects, and to present new techniques, such as the SABRE method or SRI, that will be used to operate certain future mining deposits. In Mongolia, Orano Mining, through its subsidiary Badrakh Energy, has organized more than 1,500 visits for local populations as well as teachers, students, and journalists since the start of the Zuuvch Ovoo pilot. Orano Mining is also pursuing its proactive and progressive approach to responsible mining activities by drawing on the best international corporate social responsibility (CSR) practices implemented, in particular, through the ICMM (International Council on Mining and Metals). Getting involved in local life around our sites To meet the expectations of its stakeholders and operational challenges, Orano participates in projects in its regions, with a priority for skills development actions and community service. In France, Orano is involved in actions relating to the mobility of its employees, as well as making its employees available for the resilience of the regions. For example, in 2021, Orano signed an agreement with the French Ministry of the Armed Forces to support the military reserve policy, which strengthens that of 2016. This new agreement supports the involvement of the group’s employees up to 10 days per year of their working time and with wage maintenance, in addition to the eight legal days. This agreement renewed a long-standing commitment to the National Guard. The majority of the group’s large industrial platform employees also have agreements with local emergency services for which they carry out voluntary work. For example, Orano la Hague has had an availability agreement with the SDIS 50 (departmental fire and rescue service) since 2009. More than 80 site employees work within the SDIS 50 in 13 rescue centers. French entities also took part in the “Tous résilients face aux risques” (Resiliency in the face of risks) event on October 13, created by the government in line with the UN’s International Day for Disaster Risk Reduction. The objective of this day is to raise awareness, inform, and accustom people to measures that reduce their risk in the event of natural or technological disasters. The 2025 edition focused on the role of feedback and incident analysis in the development of new prevention systems. It was an opportunity to remind people of the measures taken to protect employees and local populations. Orano is committed to promoting its employees’ commitment to local democracy. In France, the group grants paid leaves of absence to employees holding a local term of office (regional council, general council, mayor or municipal councilor, etc.) who inform the group. The number of days varies according to the level of the term of office, between 3 days (municipal councilor) and 12 days (Chairman or vice-Chairman of the regional or departmental board). In 2025, around 60 employees in France made themselves known to the group and requested to benefit from the scheme. Getting involved in societal projects around mining sites As part of its CSR policy and societal commitments, Orano Mining places education central to its priorities. The objective is not only to help improve the educational infrastructure but above all promote the development of skills in the regions and create a positive longterm impact for local communities. With this in mind, Orano Mining plans a gradual increase of 20% in societal spending on societal projects over the period 20252030. In 2025, Orano Mining’s societal spending on education will represent 9% of its total societal investments. This is reflected in the implementation of a training program, and in better access to quality education for local communities. Orano Mining supports the implementation of learning pathways, contributes to the improvement of educational conditions and promotes skills development through targeted programs and strong partnerships with educational institutions. Awarding scholarships is one of the four pillars of this strategy and is deployed in all the countries in which Orano Mining operates. In 2025, 294 scholarships were funded in all the countries where Orano Mining operates. In Kazakhstan, in accordance with regulatory requirements relating to the use of the subsoil, Katco has developed partnerships with national and regional universities to implement a scholarship program to promote access to higher education. This scheme benefits talented students from vulnerable families living near our operating sites. It also targets children from single-parent or large families of Katco employees, as well as children of company employees, thus contributing to local capacity building and equal opportunities. A similar program has been deployed in Mongolia since 2010. It awards scholarships to students intending to work in public administration, health and education. In return for their scholarship, the beneficiaries undertake to return to their region at the end of their studies, thus contributing to the development and strengthening of skills locally. Orano Canada has renewed its partnership with the Indigenous Student Achievement Pathways (“ISAP”) program implemented by the University of Saskatchewan for young people from indigenous populations. Over the next two years, they will receive remedial classes in mathematics, digital technology, and geology to enable them to approach their studies in the best possible conditions.
