Nippon Steel Corp. received US approval for its $14.1 billion acquisition of United States Steel Corp., to create one of the world's largest steel companies. The deal includes a national security agreement and substantial monetary investments.

United States Steel shares are jumping in premarket trading Monday, as the Pittsburgh-based company’s takeover by Japan’s Nippon Steel looks set to close following the deal's approval by President Donald Trump.

With President Donald Trump’s blessing, Nippon Steel can complete its “investment” in U.S. Steel. It’s really an acquisition.

President Trump’s foray into the takeover could reshape the future of foreign investment in the United States.

Nippon Steel’s $14 billion US Steel deal raises investor concerns over financing, control via golden share, and high acquisition premium.

The downgrade follows U.S. President Donald Trump’s executive order on June 13 allowing Nippon Steel to proceed with its $14.1 billion all-cash acquisition of U.S. Steel. Jefferies warned that the transaction will pressure Nippon Steel’s financials in the near term as it may need to lower earnings guidance and raise fresh equity.

The companies said they had entered into an agreement with the U.S. government to alleviate any national security concerns.

Trump admin officials provided additional insight into the "golden share" arrangement that the federal government made as a condition for supporting the deal.
