President Trump said on Friday that Intel, the troubled Silicon Valley chipmaker, had agreed to give the U.S. government a 10 percent stake in its business, worth $10 billion.

Speaking at news conference, Mr. Trump said the agreement came out of negotiations last week with Lip-Bu Tan, Intel’s chief executive.

“I said, ‘I think it would be good having the United States as your partner.’ He agreed, and they’ve agreed to do it,” Mr. Trump said. “And I think it’s a great deal for them.”

Intel declined to comment.

Mr. Trump had called for Mr. Tan’s resignation in a social media post earlier this month. Days later, Mr. Tan met with Mr. Trump at the White House and discussed giving the U.S. government an equity stake in the chipmaker.

On Friday, Mr. Trump didn’t provide any specifics about how the deal would work. In prior discussions, the administration had proposed converting $10.86 billion in recent federal grants into equity in Intel, which is worth about $100 billion.

If the effort happens, it would be among the largest government interventions in a U.S. company since the rescue of the auto industry after the 2008 financial crisis. To prevent the collapse of Chrysler and General Motors, the government poured tens of billions of dollars into the companies and helped them reorganize. The maneuver is believed to have saved more than a million auto industry jobs.

A deal is likely to need approval by Intel’s board of directors. It could also face a challenge from shareholders or others in the industry concerned about its legality.
