Nippon Steel Corp. announced Thursday it has withdrawn its civil lawsuit against U.S. steel giant Cleveland-Cliffs Inc. and the president of the United Steelworkers (USW), among others, related to its acquisition of United States Steel Corp.

The USW announced Wednesday it has also withdrawn its complaint filed with the National Labor Relations Board alleging unfair labor practices by U.S. Steel.

With the latest actions, all litigation and disputes surrounding the acquisition have been concluded.

In January this year, Nippon Steel and U.S. Steel sued Cliffs, its CEO Lourenco Goncalves and USW International President David McCall in a U.S. court, alleging coordinated actions to block the acquisition plan. They sought damages and injunctions against what they called illegal acts.

Nippon Steel stated that its reason for withdrawing the lawsuit was "to conclude the litigation, as the acquisition has been completed." According to Nippon Steel, no financial or other consideration was exchanged regarding the termination of the lawsuit.

The acquisition plan, announced by Nippon Steel in December 2023, became politicized, with U.S. presidential candidates expressing opposition, among other responses. In January this year, following then U.S. President Joe Biden's order prohibiting the acquisition on national security grounds, Nippon Steel and U.S. Steel sued President Biden and the Committee on Foreign Investment in the United States (CFIUS), seeking to invalidate the prohibition order, among other court actions.

In June, Nippon Steel completed the full acquisition of U.S. Steel with U.S. President Donald Trump's approval. Nippon Steel then withdrew its administrative lawsuit against Biden and CFIUS in July.
