Who runs ArcelorMittal?
Aditya Mittal has been CEO since 2021. His father Lakshmi Mittal, founder of Mittal Steel, serves as executive chairman.

The company combines two lineages. Arcelor formed in 2002 from the three-way merger of Luxembourg's Arbed, France's Usinor, and Spain's Aceralia, consolidating Western Europe's premier flat-steel franchises. Arbed itself traced to 1911 and Luxembourg's nineteenth-century steel industry.

Mittal Steel was built by Lakshmi Mittal beginning in 1976, when he took over a small Indonesian mill his family had established. Over three decades he assembled the world's largest steel group by buying distressed plants in emerging and post-communist markets: Trinidad and Tobago, Mexico, Kazakhstan, Romania, the Czech Republic, Poland, Bosnia, South Africa, and the United States, where his 2004 merger with International Steel Group created Mittal Steel Company.

In January 2006 Mittal Steel launched a hostile bid for Arcelor. The fight drew in European governments and dominated business headlines for five months. In June 2006 the sides agreed to combine at about 40.37 euros per share, valuing Arcelor near 33 billion dollars, with the Mittal family accepting a reduced stake and governance constraints including a standstill on building control without independent director approval.

Mittal Steel took control in August 2006, and the 2007 merger created ArcelorMittal, headquartered in Luxembourg per the merger agreement. The new giant produced roughly 10 percent of global steel output.

The years since brought both expansion and retreat. It bought Essar Steel's Hazira plant in India in 2019 via the AMNS India joint venture with Nippon Steel, while selling its US integrated mills to Cleveland-Cliffs in 2020. China Baowu surpassed it as the largest producer in 2019. In 2025 the company posted sales of $61.4 billion, EBITDA of $6.5 billion with margins described as structurally improved versus prior cycles, record iron ore shipments from Liberia, and a growing renewables business in India.

As one of the largest industrial emitters, ArcelorMittal commits to a 25 percent reduction in CO2 intensity by 2030 and net zero in Europe by 2050. Programs include hydrogen-ready DRI units, electric arc furnace conversions at Gijon and Dunkirk, carbon capture trials, and the XCarb recycled steel line. India is the focus of a major renewables build to supply cleaner power to steel plants.

Scrutiny comes from groups like SteelWatch, which argue capital returns to shareholders exceed green investment. Labor relations in legacy European plants involve ongoing restructuring tension, and mining operations face community and environmental review in Liberia and Canada.

The company appears annually on Fortune's Global 500 and ranks at or near the top of World Steel Association producer tables. Its automotive steels and S-in motion vehicle lightweighting program have earned industry recognition, and AMNS India's expansion ranks among the largest current steel growth projects globally.

ArcelorMittal's history includes periodic industrial incidents and labor disputes at legacy plants, an ongoing EU environmental compliance workload, and litigation around its Kazakh coal mines, which it divested after the 2023 Kostenko disaster killed dozens of miners. The company has faced criticism for the pace of decarbonization relative to profits and for closing or idling European blast furnaces during weak demand periods.
