Operating results for the six months ended June 30, 2025 as compared to six months ended June 30, 2024

The following discussion and analysis should be read in conjunction with ArcelorMittal's interim condensed consolidated financial statements included in this report. ArcelorMittal reports its operations in six segments: North America, Brazil, Europe, India and JVs, Sustainable Solutions and Mining.

Key indicators

The key performance indicators that ArcelorMittal’s management uses to analyze performance and operations are the lost time injury frequency ("LTIF", referring to "lost time injury frequency rate equals lost time injuries per 1,000,000 worked hours, based on own personnel and contractors") rate, sales, average steel selling prices, crude steel production, steel shipments, iron ore production and operating income. Management’s analysis of liquidity and capital resources is driven by net cash provided by operating activities.

Health and safety

The Company is in the first year of a three-year transformation program to implement the recommendations of the nine-month Group-wide safety audit undertaken by dss+ in 2024. The recommendations subsequently informed bespoke unit-level action plans designed to transform ArcelorMittal into a zero fatality and serious injury business. In 2025, the Company is focused on setting the foundations for change across the whole Group. During years two and three, these changes will be embedded to ensure consistency, discipline and results in every region supporting the Company to reach and remain at world-class levels of safety performance.

Key areas of progress in 2025 included:

• Operational risk exposure (recommendation 1): To strengthen the identification and understanding of operational risk exposure, the Company has provided clear guidance for sites including on hazard identification, risk assessment and control, amongst other areas. These requirements bring together best practices from the organization and outline how to manage risk in a consistent way. In addition, approximately 890 Self-assessment fatality prevention standard audits ("Self-assessments") were carried out by operational units since January 2025. These steps are supporting the Company in building a more consistent, preventative and risk-informed culture across the Group.

• Assurance model (recommendation 2): The assurance model has been strengthened, with three lines of audits
