US Steel, Nippon Steel seek US security review of takeover deal

US Steel Corp and its potential buyer Nippon Steel of Japan are requesting a federal review of their proposed deal following congressional criticism that the transaction threatens US national security, US Steel said Thursday.

The companies asked the Committee on Foreign Investment in the United States — an interagency body established to review foreign takeovers of US companies — to evaluate Nippon’s $14.1 billion takeover of Pittsburgh-based US Steel.
