During a recent joint news conference, President Donald Trump stated that Japan's Nippon Steel will not acquire U.S. Steel but will instead make a substantial investment in the company. This move comes after former President Joe Biden blocked Nippon's nearly $15 billion bid over national security concerns. Trump mistakenly referred to Nippon as Nissan but clarified that Nippon's investment would foster mutual benefits, with promised technology enhancements for U.S. Steel's production. Despite this commitment, U.S. Steel shares fell by nearly 6%, indicating investor uncertainty about the implications of the planned investment and future ownership stakes.
