Nippon Steel finalized its $14.9 billion acquisition of US Steel, creating a global steel giant. The deal, initially controversial due to national security concerns raised during the US presidential election, was approved after Nippon made concessions including a government "golden share", significant US investment commitments ($11 billion by 2028), and pledges to maintain US jobs and headquarters. These concessions addressed concerns about foreign control over a major US steel producer.
