Pursuant to Section 220 of Delaware Law, Ancora has Submitted a Books and Records Request Related to Issues That Include U.S. Steel's Futile, Wasteful Efforts to Revive the Dead Sale to Nippon

Ancora Holdings Group, LLC (collectively with its affiliates, "Ancora" or "we"), a shareholder of United States Steel Corporation (NYSE:X) ("U.S. Steel" or the "Company"), today announced it will host a live investor conference call entitled, "A U.S. Solution for U.S. Steel." The call will be hosted by James Chadwick, President of Ancora Alternatives LLC, and Alan Kestenbaum, CEO candidate and the architect of the legendary turnaround of Stelco Holdings Inc. (TSX:STLC), who will provide analysis and take questions. The call takes place tomorrow, February 19^th, at 10:00 a.m. Eastern. Register and join at https://bit.ly/AncoraXInvestorWebinar.

As a reminder, Ancora recently nominated nine highly qualified, independent candidates for election to U.S. Steel's Board of Directors (the "Board") at the 2025 Annual Meeting of Stockholders (the "Annual Meeting"). In connection with its campaign, the firm has independently submitted a books and records request letter to U.S. Steel's Board, pursuant to Section 220 of the Delaware General Corporation Law. The letter seeks to help Ancora achieve the following:

Investigate whether U.S. Steel's Board and management breached their fiduciary duties by, among other things, wasting corporate resources and carrying out a potentially disloyal pursuit of the seemingly dead transaction with Nippon Steel Corporation.
Investigate potential wrongdoing with respect to insider trading on the part of insiders, including CEO David Burritt, around the time in which U.S. Steel was assessing transaction options in 2023. Ancora has never before seen an executive put in place a 10b5-1 plan, with trigger prices in the neighborhood of subsequently submitted bids, during what appears to have been a fluid review of strategic options.
Investigate whether the Board is violating its duty of loyalty by taking actions to improperly entrench itself ahead of the Annual Meeting.
Assess whether to take action in response to the results of the investigation, including potential litigation against U.S. Steel and Mr. Burritt, amongst others.
Enhance communication with other shareholders regarding relevant matters, so that other shareholders may effectively address any mismanagement, improper conduct or breach of fiduciary duties.
