Watch: Watch Q1 2026 results for early performance of the Mardyck unit and its margin profile versus traditional steel—this proves the economics before the 2029 Dunkirk ramp. Any delay signals execution risk or cost overruns that could pressure returns.
ArcelorMittal is doubling down on low-carbon steel production with €1.8 billion in near-term capex across two facilities. A €500 million electrical steel unit at Mardyck launches this quarter, while a €1.3 billion electric arc furnace at Dunkirk—funded 50% through French subsidies—starts production in 2029 with 2-million-tonne capacity. The Dunkirk EAF cuts CO2 emissions by 3x versus traditional blast furnaces and secures a long-term low-cost electricity contract with EDF, a structural advantage in decarbonizing steel markets.
These investments lock ArcelorMittal into premium pricing for low-carbon steel while competitors lag in capex. Government co-funding (50% of Dunkirk) compresses returns on capital and subsidizes the transition—de facto hedging against future carbon regulation. The secured electricity contract removes price volatility, the single biggest margin risk for EAF operators.
