ORANO // Annual Activity Report 2024

SUSTAINABILITY STATEMENT

Environmental information

4.2.3.6 Financial effects related to biodiversity and ecosystems Orano is working to quantify the fi nancial effects related to risks and opportunities in terms of biodiversity and ecosystems. The group plans to publish these within three years, in accordance with the phase-in provision provided for by the standard (three years).

4.2.4 A responsible management of our liabilities [E2]

4.2.4.1 IROs related to the management of liabilities 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 .

In order to determine the IROs for the “Pollution” theme, Orano relied on interviews with its stakeholders, its risk analyses and its impact studies. The group has determined that “Management of liabilities and end-of-life of sites” is material. This topic is also included in the EFRAG draft sector guide on mining activities.

POTENTIAL IMPACT OF AN ACCIDENTAL SPILL OF RADIOACTIVE OR HAZARDOUS SUBSTANCES An accidental spill of hazardous or radioactive substances (environmental incident, breakwater, etc .) can cause environmental scars. Accidental pollution would impact the environment, as well as the working conditions of employees, the living conditions of local residents and the group’s image. Through its actions and investments in nuclear and industrial safety, Orano makes every effort to avoid accidental spills and limit their consequences on people and the environment. FINANCIAL RISK RELATED TO ENVIRONMENTAL INCIDENTS, LIABILITY MANAGEMENT AND SITE REMEDIATION Incidents, poor management of the environmental responsibility of industrial and mining sites (historical scars, failure to manage long-term mineral processing residues, changes in regulations, etc .) would have a negative impact on the group’s fi nances. Additional costs in terms of environmental incidents or remediation are likely to impact the group’s results. Reputational damage is likely to impact the group’s revenue. Through its actions in terms of nuclear safety and industrial safety, Orano makes every effort to avoid accidental spills and limit their consequences. Regular assessments of provisions for the end-of-life of sites and the remediation of mining sites are carried out so that provisions can be updated. Orano has 8 billion euros in assets to cover the end-of-life expenses of its facilities. Changes in regulations concerning the dismantling conditions of nuclear sites, the review of the initial state of the facility at the time of dismantling or its update, and the increase in project execution costs would increase dismantling costs of the group’s facilities. The main risk for the group is related to the uncertainty that the amounts provisioned for end of-lifecycle operations will correspond to the costs actually incurred by the group in respect of its dismantling obligations. It is therefore possible that end-of-lifecycle obligations and the associated expenses or an additional obligation of a nuclear or environmental nature that the group may subsequently have to bear could have a signi fi cant negative impact on its fi nancial position.
