07:32 AM EST, 01/27/2025 (MT Newswires) -- United States Steel ( X ) said Monday it has rejected an attempt by activist investor Ancora Catalyst Institutional to change its board of directors and drop an attempt to be acquired by Japan's Nippon Steel.

"U.S. Steel has an experienced and independent board of directors with a proven track record of acting in the best interests of the Company and creating value for stockholders," the company said. "We remain confident that our partnership with Nippon Steel is the best deal for American steel, American jobs, American communities and American supply chains."

The company said Ancora holds a 0.18% stake in U.S. Steel and is attempting to replace nine board members.

"Ancora's interests are not aligned with all U.S. Steel stockholders," the company said. "Our stockholders will not be well served by turning over control of the company to Ancora."

Ancora did not immediately reply to MT Newswires' request for comment.
