Stockholder FAQ

• When is U. S. Steel’s Annual Meeting of Shareholders?

  This year's annual meeting is scheduled for May 6, 2025. Stockholders of record as of March 10, 2025, are entitled to vote at the 2025 Annual Meeting.

• What color is the U. S. Steel proxy card?

  In your package of voting materials, you will have received a WHITE proxy card or WHITE voting instruction form for U. S. Steel (both of which are referred to as your WHITE proxy card).

• What should I do with the gold proxy card?

  You may have also received gold proxy materials from Ancora – which we encourage you to discard immediately.

• What happens if I voted using another card?

  If you mistakenly vote using the gold proxy card, you can always cancel that vote by using the WHITE proxy card to vote again either electronically or by mail. Only your latest dated vote will count!

• What if I voted for more than 10 directors?

  Remember to vote “FOR” ONLY U. S. Steel’s 10 nominees on the WHITE proxy card. If you mark “FOR” for more than 10 nominees, your vote with respect to election of directors will be invalid and will not be counted.

• What happens if the Transaction with Nippon Steel is not approved?

  The same management team and Board that ran a full and fair process to obtain a $55 per share cash offer can be counted on to continue to maximize value for stockholders and help drive operational outperformance when compared to industry peers.

  Since the Board named Dave Burritt as CEO in 2017, the Company has undertaken a bold, strategic transformation that has changed U. S. Steel into the modern, innovative steel producer it is today.

  Our Board is urging all stockholders to vote FOR U. S. Steel’s 10 nominees to ensure our Board can continue to take actions that are in the best interest of all stakeholders, drive the business forward, and pursue all paths to deliver $55 per share to our stockholders.
