Biden Blocks Nippon Steel’s $14.1 Billion Takeover of US Steel

President Joe Biden has blocked the $14.1 billion sale of United States Steel Corp. to Nippon Steel Corp., killing a high-profile deal that sparked a political firestorm and tensions between the US and Japan.

Biden announced his formal decision on Friday after the case was referred to him by a US security review panel, ahead of a deadline early next week.

“We need major U.S. companies representing the major share of US steelmaking capacity to keep leading the fight on behalf of America’s national interests,” Biden said in a written statement, adding that the deal “would place one of America’s largest steel producers under foreign control and create risk for our national security and our critical supply chains.”

Shares of US Steel dropped 5.5% to $30.80 at 9:35 a.m. in New York. US Steel and Nippon Steel didn’t immediately comment on Biden’s decision.

The companies have signaled that they may challenge the legal grounds of any block, raising the prospect that the matter will remain in dispute. President-elect Donald Trump has also pledged to block the transaction.

Investors had priced in low odds that the offer of $55 a share would proceed, but Biden’s decision may cap a year-long saga, despite concessions from Nippon Steel regarding employment, investment and local leadership.
