Nippon Steel said on Wednesday it has resolved all legal disputes with the United Steelworkers union and steelmaker Cleveland-Cliffs tied to its $14.9 billion acquisition of US Steel, which closed in June.
The settlement includes the dismissal of a lawsuit brought by Nippon Steel, its North America unit and US Steel against USW president David McCall, as well as the withdrawal of an unfair labor practice charge the union had filed against US Steel with the National Labor Relations Board.
The companies also dropped claims involving Cleveland-Cliffs and its CEO Lourenco Goncalves, who had opposed the deal.
Nippon and US Steel had accused Cleveland-Cliffs, its CEO Lourenco Goncalves and United Steelworkers president David McCall of trying to block the deal.
The union had also filed an unfair labor practice charge with the National Labor Relations Board, alleging US Steel intimidated workers and sought to suppress opposition to the sale.
The buyout, announced in late 2023 and completed on June 18, 2025, faced months of political scrutiny and union resistance over foreign ownership of a storied American steelmaker.
Nippon said no financial compensation was exchanged as part of these settlements. The parties added they remain focused on steelmaking operations and collective bargaining.
