Nippon Steel Corp. has finalized its $14.1 billion acquisition of US Steel, completing an 18-month merger effort and creating the world’s second-largest steelmaker. The $55-per-share cash deal gives Nippon Steel a strategic U.S. presence while sidestepping Trump’s 50% steel tariffs. The New York Stock Exchange halted trading in U.S. Steel shares early Wednesday, marking the deal’s closure. On Friday, the companies reached a conditional agreement with Trump’s administration that permitted the acquisition to proceed. The deal followed Nippon’s commitment to invest an additional $11 billion in U.S. Steel’s Pittsburgh operations.
