ArcelorMittal S.A. is a Luxembourg-headquartered multinational steel and mining corporation established in 2006 through the merger of European steelmaker Arcelor and India's Mittal Steel. As the world's second-largest steel manufacturer after China's Baowu, the company operates across more than 60 countries with a workforce of approximately 125,554 employees and maintains major steel production facilities in 14 countries. The company is listed on the New York Stock Exchange under ticker MT and on Euronext.
Core Business
ArcelorMittal's core operations center on construction steel, producing structural beams, H-sections, rebar, and high-strength building plate—materials that have been featured in landmark projects such as the One World Trade Center reconstruction. The company also serves the renewable energy sector through its proprietary Magnelis® zinc-aluminum-magnesium coated steel, which has become an industry benchmark for solar mounting systems worldwide. For full-year 2025, the company produced 55.6 million metric tonnes of crude steel and 48.8 million tonnes of iron ore, with the latter increasing 15.1% year-over-year.
Additional business segments include custom metal fabrication for bridges and seismic applications, where the company leverages advanced engineering capabilities to serve critical infrastructure projects. ArcelorMittal has also developed a significant presence in green building materials under its XCarb® low-carbon certification program, positioning itself to capture growing demand for sustainable construction solutions across global markets.
Global Presence
The company maintains dominant market share in Europe and commands significant pricing power in premium automotive sheet and specialty construction steel. With production facilities spanning 14 countries and operations in over 60 nations, ArcelorMittal has established an extensive global footprint that enables it to serve customers across diverse regional markets. In the United States, the company completed the full acquisition of AM/NS Calvert, further strengthening its North American platform.
Key Strengths
ArcelorMittal's competitive positioning derives from exceptional vertical integration, with iron ore self-sufficiency reaching 72% and global reserves of 370 million tonnes—providing substantial cost advantages and supply chain security. The company holds strong brand recognition and technological leadership that create substantial barriers to entry in high-margin specialty segments. With upgraded credit ratings from Moody's and S&P, improved profitability delivering net income of $3.15 billion (up 135% year-over-year), and management confidence reflected in increased dividends and ongoing share repurchases, the company is well-positioned for continued growth in a challenging global steel market.
