Sept 3 (Reuters) - Nippon Steel ( NISTF ) said on

Wednesday it has resolved all legal disputes with the United

Steelworkers union and steelmaker Cleveland-Cliffs ( CLF ) tied

to its $14.9 billion acquisition of U.S. Steel, which closed in

June.

The settlement includes the dismissal of a lawsuit brought

by Nippon Steel ( NISTF ), its North America unit and U.S. Steel against

USW President David McCall, as well as the withdrawal of an

unfair labor practice charge the union had filed against U.S.

Steel with the National Labor Relations Board.

The companies also dropped claims involving Cleveland-Cliffs ( CLF )

and its CEO Lourenco Goncalves, who had opposed the deal.

Nippon and U.S. Steel had accused Cleveland-Cliffs ( CLF ), 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 U.S. 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.
