President Joe Biden announced on Jan. 3 that he is blocking the proposed takeover of U.S. Steel by Japanese company Nippon Steel.
Nippon Steel had proposed paying $15 billion to take over US Steel.
Biden had 15 days following the referral to block or approve the deal. If he had not acted, the deal would have been approved.
Nippon’s 2023 agreement included several concessions, including giving the U.S. government veto power over changes to output.
U.S. Steel shareholders voted in 2024 to approve the acquisition, though the proposal was opposed by the United Steelworkers union.
The companies alleged that the decision violates federal law and that Biden’s statement did not “present any credible evidence of a national security issue, making clear that this was a political decision.”
“Following President Biden’s decision, we are left with no choice but to take all appropriate action to protect our legal rights,” they stated.
Nippon Steel previously threatened legal action if the deal was blocked.
U.S. Steel has warned that thousands of jobs would be at risk without the deal.
Shares of U.S. Steel were down 5.5 percent to $30.75 on the New York Stock Exchange.
Japanese industry and trade minister Yoji Muto also expressed disappointment over Biden’s decision, saying it was both difficult to understand and regrettable.
“There are strong concerns from the economic circles of both Japan and the U.S., and especially from Japanese industry regarding future investments between Japan and the U.S., and the Japanese government has no choice but to take this matter seriously,” he said in a statement via email.
“I am totally against the once great and powerful U.S. Steel being bought by a foreign company,” Trump said at the time.
It is unclear whether another buyer will emerge. U.S. Steel has reported nine consecutive quarters of falling profits amid a global downturn in the steel industry. U.S.-based Cleveland-Cliffs, which previously bid for the company, has seen its share price fall to the point where its market value is lower than that of U.S. Steel.
