HARRISBURG, Pa. — The bid by Japan’s Nippon Steel to buy U.S. Steel may have a new lease on life after the Biden Administration extended a deadline for the Japanese steelmaker to abandon plans to acquire the storied Pittsburgh company after President Joe Biden blocked the deal.

The new deadline, now in mid-June, was viewed by U.S. Steel — and investors — as an opportunity for the companies to complete the acquisition, even though President-elect Donald Trump, who takes office in a week, also opposes the deal.

Biden nixed the acquisition this month citing a potential threat to national security, though the U.S. Committee on Foreign Investment in the United States, known as CFIUS, failed to reach a consensus on the security issue.

“We are pleased that CFIUS has granted an extension to June 18, 2025, of the requirement in President Biden’s Executive Order that the parties permanently abandon the transaction,” U.S. Steel said in a statement Sunday. “We look forward to completing the transaction, which secures the best future for the American steel industry and all our stakeholders.”

The proposed deal kicked up an election-year political maelstrom across America’s industrial heartland and quickly drew promises by Biden and Trump from the campaign trail in a crucial battleground state to block the deal.

However, a CFIUS composed of Trump appointees and Trump himself may be free to allow the deal to go through, or negotiate new terms.

Dennis Unkovic, a Pittsburgh lawyer who works on international business transactions, including deals in which the committee’s approval was required, said a new CFIUS and a new president are not legally bound by Biden’s decision.

CFIUS giving the parties an extra six months to unwind the deal is unusual, Unkovic said. It wasn’t immediately clear why CFIUS extended the deadline, but Unkovic pointed to reports that Biden’s CFIUS was divided over whether it was a security threat.
