According to the official legislative dossier, the bill was adopted without amendments by the National Assembly on June 11, 2026 and submitted to the Senate for further consideration.
ArcelorMittal France operates about 40 enterprises in the country, including large steel mills in Dunkirk and Fos-sur-Mer. The nationalization proposal was supported by workers and leftist lawmakers concerned about the future of domestic steelmaking capacity.
Still requires Senate approval
The bill has not yet become law. It still has to pass through the Senate, which previously rejected an earlier version of the proposal in February 2026.
According to the text of the law, the proposed structure provides for the creation of an administrative commission responsible for determining the purchase price of ArcelorMittal France if nationalization continues.
ArcelorMittal opposes nationalization
ArcelorMittal opposed the proposal, arguing that separating its French operations from the broader group would worsen the facilities situation. The company also pointed to the large investments made in France in recent years.The debate is unfolding at a time when France and the European steel sector as a whole are facing pressure due to weak demand, global overcapacity, high energy costs and the need to finance decarbonization projects.
Steel remains a central part of French industrial policy
Supporters of the bill argue that the steel industry is strategically important for France's manufacturing base, energy transition, infrastructure, and defense needs.
The future of ArcelorMittal's French businesses has become part of a broader political debate about how far the state should intervene to preserve strategic industrial assets.
