Nippon Steel clarified its spending plans at U.S. mills owned by U.S. Steel Corp. as part of last-ditch efforts to win over workers and politicians for its bid to buy the steelmaker.

KASHIMA, Japan — The signs at Nippon Steel read: “The world through steel,” underlining why Japan’s top steelmaker is pursuing its $15 billion bid to acquire U.S. Steel.

Nippon Steel reiterated confidence that its $14.1 billion acquisition of U.S. Steel Corp. can be completed by year-end, even as the current and incoming presidents oppose the takeover.

President-elect Donald Trump reiterated his opposition to the sale of U.S. Steel Corp. to Nippon Steel Corp., saying he’d instead use tariffs and tax incentives to revive the steelmaker.

President-elect Donald Trump’s plan to impose 25% tariffs on all goods from Canada and Mexico will push up steel and aluminum prices across the U.S., according to Citigroup analysts.

Nippon Steel Corp. is promising unionized workers of United States Steel Corp. that it won’t send steel shipments from its overseas mills as part of its commitments to seal a $14.1 billion takeover of the American company.

Nippon Steel Corp. said it still expects its $14.1 billion acquisition of United States Steel Corp. to complete by the end of the year.

A U.S. arbitration panel has come out in favor of U.S. Steel in a dispute with union workers over Nippon Steel’s plan to buy the Pittsburgh-based company, according to the United Steelworkers.

A U.S. security panel has granted Nippon Steel permission to refile its plans to purchase United States Steel for $14.1 billion, likely pushing a decision on the takeover past the elections.

United States Steel Corp. surged the most this year after The Washington Post reported that President Joe Biden wouldn’t immediately move to block Nippon Steel Corp.’s takeover bid.
