• Nippon Steel increases investment commitment to $7 billion upon deal closure, a $2.7 billion bump from prior offers.
  • U.S. Steel shares surge 13% as Trump orders fresh CFIUS review of the previously blocked $14.1 billion acquisition.
  • Deal faces 45-day national security review, with Nippon Steel pledging job preservation and U.S. Steel's iconic status.

Regulatory Reassessment Underway

Nippon Steel has sweetened its offer to invest $14 billion in U.S. Steel's operations should regulators approve its contentious acquisition, according to people familiar with the matter. The Japanese steelmaker's revised commitment includes a $7 billion infusion upon closing—$2.7 billion more than earlier proposals—as it seeks to overcome political resistance to the deal.

The development follows President Donald Trump's April 7 directive for CFIUS to reevaluate the transaction, which the Biden administration had blocked over national security concerns. The review period runs 45 days, putting a potential decision timeline in late May or early June 2025. Market reaction was immediate: U.S. Steel shares jumped 13% on the news as investors bet on improved approval odds.

Political and Industrial Stakes

At $14.1 billion, the proposed acquisition represents more than a corporate transaction—it's become a litmus test for foreign investment in sensitive sectors. Nippon Steel has emphasized that no jobs would be lost and U.S. Steel's legacy would remain intact, while analysts note the target's standalone valuation has climbed from $11 to $43 per share since 2019.

Behind the scenes, advisors are urging Nippon Steel to articulate how the deal strengthens U.S. national security, according to documents reviewed. The argument centers on technological transfers and global competitiveness, though steel unions remain skeptical. "This isn't just about capital—it's about proving this makes America stronger," said one investment banker close to the talks, who asked not to be named discussing private deliberations.

What Comes Next

With CFIUS examiners now combing through mitigation proposals, both companies face weeks of uncertainty. The review's outcome could reshape the American steel industry and set precedents for cross-border deals in strategic sectors. For now, traders are watching the clock: any slippage past the 45-day window would likely pressure U.S. Steel's stock back toward pre-announcement levels.
