atch® steel offer was developed to provide steel grades suitable for H2-linepipes. The production of a complete range of low-CO 2 steels allows for a reduction in carbon footprint by up to 65%. More than 50 new XCarb® Recycled and Renewably Produced ("RRP") products have been commercialized in 2024 and more than 200 other new products are under development. XCarb ® RRP steels (flat, long, tubular, profiles, sandwich panels) have been incorporated in Steligence ® building concepts. Steligence ® is the holistic platform for environmentally friendly and cost-effective steel solutions for circular use (design for re-use), resilience with respect to exceptional events (floods and storms), as well as solutions for thermal retrofit or solar energy harvesting. In process research, the focus remains on innovations in the following domains: By-products and circular economy. In 2024, the Company characterized the production of new steel routes by-products under different operational conditions to foresee the qualities and quantities of the new by-products mix. In 2024, LCA was

calculated to com pare the use of slag to replace other materials. As an example, Sidercal® is a slag-based steel by-product used in roads construction in the sub-base and as pavement. Other circular economy initiatives include working on the use of mining tailings as a secondary raw material, either by finding marketable solutions or generating valuable products to be used in-house and in construction. Progress against air pollution . In 2024, information of all studies and real data monitoring were analyzed, concluding that control measures implemented in the yards in Tubarão have been effective in reducing dust emissions. ArcelorMittal also has research activities focused on innovative gas cleaning technologies (Nitrogen Oxides (“NOx”) , Sulphur Oxides ("SOx") ). In 2024, R&D tests proved significant NOx emissions reduction (up to 50%) at a semi-industrial scale. Progress in water management. ArcelorMittal is investigating solutions to reduce water vulnerability in some areas. In 2024, R&D initiated a smart pilot plant in Tubarão (Brazil) to monitor basic water quality parameters with a collection of sensors powered by solar energy. This pilot plant delivered promising results during the test phase during the year. R&D continues supporting ArcelorMittal’s three decarbonization paths for primary activities: The Company's ongoing Volteron™ project is
