Overview

• President Trump directed the Committee on Foreign Investment in the U.S. (CFIUS) to reassess Nippon Steel's proposed acquisition of U.S. Steel within 45 days.
• The review follows Biden's January 2025 decision to block the deal over national security and supply chain risks, prompting lawsuits from both companies.
• U.S. Steel shares surged 16% following the announcement, reflecting investor hopes for a potential reversal of the deal's rejection.
• Trump's directive includes evaluating whether proposed measures sufficiently address national security concerns raised by the acquisition.
• The move highlights shifting U.S. policy on foreign control of strategic industries, with unions and critics still warning of risks to domestic steelmaking and jobs.
