Chronology of Nippon Steel's Attempt to Acquire U.S. Steel

The timeline details major incidents in relation to Nippon Steel Corp.'s proposed acquisition of United States Steel Corp. On January 3, 2025, President Joe Biden, citing national security issues, issued an order to block the sale of U.S. Steel to Nippon Steel. Shortly thereafter, Donald Trump returned to the presidency, and on February 7, he announced that Nippon Steel would not proceed with the acquisition but would instead make significant investments in U.S. Steel.

In early April, Takahiro Mori, the vice chairman of Nippon Steel, communicated plans to U.S. officials regarding increasing capital investment. Following this, on April 7, Trump instructed the Committee on Foreign Investment in the United States to evaluate Nippon Steel's takeover proposal anew. As the situation progressed, Trump emphasized a cooperative relationship between Nippon Steel and U.S. Steel on May 23, stating that U.S. Steel would continue to be under American control.

On June 12, Trump remarked that the United States holds a "golden share" in U.S. Steel, further asserting its dominance in the matter. The events concluded on June 13 when Nippon Steel officially declared that the U.S. government had approved its plan for acquisition.
