Ancora Sends Letter to U.S. Steel Stockholders Regarding its Slate's Win-Win Solution to Maximize Value

Affirms Slate's Commitment to Pursuing the $55 per Share Sale to Nippon While Simultaneously Positioning U.S. Steel to Thrive Under an Alternative Standalone Scenario

Details Proposed CEO Alan Kestenbaum's Five-Point Plan to Reverse the Burritt-Dominated Board's Mistakes and Revitalize U.S. Steel's Structurally Advantaged Union Plants Across the Rust Belt

Highlights How Five-Point Plan Will Enable U.S. Steel to Deliver a $19.25 per Share Special Dividend and Target a Pro Forma Total Stockholder Return of $75+

Underscores View That Stockholders Will Face Irreversible Value Destruction Under the Burritt-Dominated Board if the Sale to Nippon Remains Blocked

Vote on the GOLD Universal Proxy Card to Elect the Entire Ancora Slate and Make U.S. Steel Great Again

Ancora Holdings Group, LLC (collectively with its affiliates, "Ancora" or "we"), a stockholder of United States Steel Corporation (NYSE:X) ("U.S. Steel" or the "Company"), today announced that it is filing a definitive proxy statement with the U.S. Securities and Exchange Commission in connection with its nomination of nine highly qualified director candidates for election to the Company's Board of Directors at the 2025 Annual Meeting of Stockholders scheduled for May 6, 2025. Additionally, Ancora sent a letter to stockholders regarding its slate's five-point plan to turn around U.S. Steel:

1. Continue to pursue the $55 per share sale to Nippon Steel Corporation. However, our nominees commit to ceasing all vengeful and frivolous litigation, such as the action against United Steelworkers President David McCall, that undermines the Company's relationships with key stakeholders.
   
   
   
   
2. If the transaction remains blocked and is then formally terminated, execute a viable strategy to achieve a target pro forma total return of $75.67 to stockholders that includes:
   
   
   
   
   • Selling the Big River Steel operation for estimated proceeds of $8 billion, netting $7.6 billion after taxes.
   • Returning $5 billion ($19.25 per share) to stockholders via a one-time special dividend.
   • Using the remaining Big River sale proceeds to invest in the Company's high-potential North American Flat-Rolled assets, resulting in an estimated 120% increase in EBITDA by the end of 2027.
     
     
     
     
3. Improve the Company's union relations in the pursuit of a new labor agreement ahead of the current deal's expiration in 2026.
   
   
   
   
4. Strengthen U.S. Steel's balance sheet to ensure the Company has the capital flexibility to pursue opportunities as they arise.
   
   
   
   
5. With a delevered balance sheet, initiate a capital allocation plan that includes regular meaningful dividend payments and share buybacks.
