The Board is taking a measured approach to considering these proposals, including seeking more information in order to evaluate proposals that are preliminary and subject to ongoing due diligence and review.”

Burritt continued, “U. S. Steel has been on a strategic journey executing a compelling transformation, building out best-in-class EAF steelmaking and finishing capabilities, while reducing our carbon footprint. Our balance sheet is stronger than ever, and we are delivering resilient cash flow while prioritizing direct returns to stockholders. The interest demonstrated by the unsolicited proposals received to date is a validation of U. S. Steel’s strategy and successful track record of execution. While the Board conducts its review of previously received proposals and other proposals it expects to receive, our entire team remains focused on safely and responsibly executing across all of our operations and advancing our Best for All® strategy, while continuing to deliver for all stakeholders.”

There is no deadline or definitive timetable set for completion of the strategic alternatives review process and there can be no assurance that this process will result in the Company pursuing a transaction or any other strategic outcome. U. S.
