Cleveland-Cliffs Signals a Possible New Bid for U.S. Steel

A possible new takeover bid for U.S. Steel emerged on Monday, teeing up more turmoil over the once-dominant company’s future after President Biden’s decision to block its acquisition by a Japanese company.

Lourenco Goncalves, the chief executive of an American competitor, Cleveland-Cliffs, said his company had “an All-American solution to save the United States Steel Corporation,” stressing that acquiring U.S. Steel was a matter of “when,” not “if.” But he offered no details of the bidding plans.

The renewed expression of interest from Cleveland-Cliffs comes less than two weeks after Mr. Biden blocked a $14 billion takeover of U.S. Steel by Nippon Steel, arguing that the sale posed a threat to national security. Cleveland-Cliffs tried to buy U.S. Steel in 2023, an offer that was rejected in favor of Nippon’s higher bid.

CNBC reported on Monday morning that Cleveland-Cliffs would seek to take over U.S. Steel and sell off its subsidiary, Big River Steel, to Nucor, another American producer. But Mr. Goncalves, at a news conference later in the day, would not confirm any partnership with Nucor on a bid.

U.S. Steel and Nucor did not immediately respond to requests for comment.

Investors seemed pleased by the potential bid, sending shares of U.S. Steel up as much as 10 percent on Monday when CNBC reported the potential offer. Shares of U.S. Steel finished about 6 percent higher on Monday but are down 23 percent over the past year, including Monday’s spike.

But the fate of Nippon’s proposed takeover remains in limbo. U.S. Steel and Nippon sued the United States government last week in the hopes of reviving their merger, accusing Mr. Biden and other senior administration officials of corrupting the review process for political gain and blocking the deal under false pretenses.
