How a historic American steel giant became a government-controlled entity under foreign ownership
In short: Once the world's first billion-dollar company, U.S. Steel faced a turbulent acquisition saga. After years of decline and intense regulatory scrutiny, the firm was finally purchased by Japan's Nippon Steel in 2025. The deal transformed the iconic manufacturer into a unique entity under significant U.S. government oversight and control.
Formed by J. P. Morgan through the merger of Carnegie Steel and other producers, U.S. Steel was once the largest company in the United States. In 1902, it produced 67 percent of all American steel. However, the company struggled for decades following the 1970s steel crisis, eventually falling to 27th in global production. By December 2023, Nippon Steel Corporation—the world's third-largest producer—agreed to acquire the Pittsburgh-based firm for $14.9 billion, a 40% premium over its stock value.
The acquisition faced fierce opposition from the Biden Administration, bipartisan lawmakers, and the United Steelworkers union, citing concerns over national security and supply chains. While the deal received regulatory approval from several nations, it remained stalled in the U.S. amid antitrust reviews and threats of a presidential block. In January 2025, President Joe Biden issued an executive order to block the merger, leading to a legal battle between the companies and the administration.
The situation shifted in May 2025 when President Donald Trump announced a revised partnership. The finalized deal, which closed on June 18, 2025, mandates that U.S. Steel maintain its Pittsburgh headquarters and be led by an American CEO. Crucially, the U.S. government secured a golden share, granting the president veto power over corporate decisions and the ability to appoint a board member. Critics, such as the Cato Institute, argue this effectively nationalizes the company, subjecting its transactions to global anti-subsidy rules.
