Phynart Studio US Steel (NYSE:X) rose 2.2% in after hours trading on reports that it won an extension to the U.S. national security review of its planned $14 billion sale to Nippon Steel (OTCPK:NISTF). The extension allows Nippon Steel (OTCPK:NISTF) to withdrawal and refile its submission to the Committee on Foreign Investment in the United States., according to a Bloomberg report late Tuesday, which cited people familiar with the matter. The New York Times also reported about the extension. The extension adds three months and pushes the review past the November U.S. election and likely keeps the deal alive as President Joe Biden has said that U.S. Steel (X) should remain an American-owned company. The current deadline for the CFIUS reviews is Sept. 23, according to multiple media reports. The latest update comes after the Washington Post first broke the news on Friday that a Biden decision on the deal wasn't likely in the near term and would likely go past the election. Biden, Vice President Kamala Harris and former President Donald Trump have all said that they oppose the deal. “The president told our steelworkers he has their backs, and he means it,” Saloni Sharma, the White House spokeswoman told the New York Times. “There is no so-called ‘delay.’ We have not received any CFIUS recommendation. The CFIUS process was and remains ongoing.” Earlier on Tuesday, US Steel (X) CEO David Burritt said he's adamant that the company's $14 billion sale to Nippon Steel (OTCPK:NPSCY) will close. \" I can't imagine it's not going to go through,\" Burritt said at an Economic Club event in Detroit on Tuesday. \"I just can't imagine that we would not have something that would not be helpful to our best ally in Asia.... It will close on its merits.\"
