1. These figures have been retrospectively adjusted for structural changes to the ArcelorMittal portfolio in the previous 12 months, and reflect emissions and production for ArcelorMittal's site portfolio as at December 2024 to enable a like for like annual comparison. 2. This indicator includes limited upstream Scope 3 emissions from purchased goods that a steelmaker would normally be expected to produce, such as coke, slabs, burnt lime in order to maintain a consistent system boundary and so a like for like comparison. Ongoing focus on tailings dam safety Tailings dam safety and structural integrity is a critical issue for all mining companies, in order to protect the safety of local communities and employees, and to protect the environment from pollution and flooding. The Company has developed a tailings governance framework based on the Mining Association of Canada (MAC), the Canadian Dam Association (CDA) and

the Global Industry Standard for Tailings Management (GISTM). The aim is to ensure that all Group tailings facilities are structurally sound and safe, with all efforts directed at minimizing risk, including independent audits benchmarked against these international guidelines. ArcelorMittal manages a total of 27 tailings storage facilities (“TSF”). These include conventional, paste, dry and in-pit facilities. There are 1 5 active, 1 dormant, 4 in care and maintenance, 3 in closure and 4 under construction facilities. To ensure their ongoing safety, a formal assurance process is in place that includes internal and external audits. This is supported by a continuous improvement program that reduces the Company's risk of existing conventional operations by promoting reduced moisture disposal methodologies (e.g. high- density thickened tailings or filtered tailings where appropriate) and proven new technologies (e.g. high-precision radar, InSAR satellite monitoring and remote instrumentation) to monitor facilities globally in real time. The Company is assessing all its mining operations for transition in line with these principles and developing customized design solutions for non-conventional tailings system management. Tailings thickening steps have been implemented in assets in Mexico, reduced moisture disposal methodologies in Brazil and Canada, and further studies are ongoing across a range of operations.
