Forward-looking statements

These slides are being provided to assist readers in understanding the results of operations, financial condition and cash flows of United States Steel Corporation as of and for the fourth quarter and full year of 2021. Financial results as of and for the periods ended December 31, 2021 provided herein are preliminary unaudited results based on current information available to management. They should be read in conjunction with the consolidated financial statements and Notes to the Consolidated Financial Statements contained in our Annual Report on Form 10-K and Quarterly Reports on Form 10-Q filed with the Securities and Exchange Commission.

This presentation contains information that may constitute "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. We intend the forward-looking statements to be covered by the safe harbor provisions for forward-looking statements in those sections. Generally, we have identified such forward-looking statements by using the words "believe," "expect," "intend," "estimate," "anticipate," "project," "target," "forecast," "aim," "should," "will," "may," and similar expressions or by using future dates in connection with any discussion of, among other things, financial performance, the construction or operation of new and existing facilities, the timing, size and form of stock repurchase transactions, operating performance, trends, events or developments that we expect or anticipate will occur in the future, statements relating to volume changes, share of sales and earnings per share changes, anticipated cost savings, potential capital and operational cash improvements, changes in global supply and demand conditions and prices for our products, international trade duties and other aspects of international trade policy, the integration of Big River Steel in our existing business, business strategies related to the combined business and statements expressing general views about future operating results. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking.Forward-looking statements are not historical facts, but instead represent only the Company's beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside of the Company's control. It is possible that the Company's actual results and financial condition may differ, possibly materially, from the anticipated results and financial condition indicated in these forward-looking statements. Management believes that these forward-looking statements are reasonable as of the time made. However, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date when made. Our Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our Company's historical experience and our present expectations or projections. These risks and uncertainties include, but are not limited to, the risks and uncertainties described in "Item 1A. Risk Factors" in our Annual report on Form 10-K for the year ended December 31, 2020 and those described from time to time in our future reports filed with the Securities and Exchange Commission.

References to "we," "us," "our," the "Company," and "U. S. Steel," refer to United States Steel Corporation and its consolidated subsidiaries, references to "Big River Steel" refer to Big River Steel Holdings LLC and its direct and indirect subsidiaries unless otherwise indicated by the context, and "Transtar" refers to Transtar LLC and its direct and indirect subsidiaries unless otherwise indicated by the context.

Explanation of use of non-GAAP measures

We present adjusted net earnings (loss), adjusted net earnings (loss) per diluted share, earnings (loss) before interest, income taxes, depreciation and amortization (EBITDA) and adjusted EBITDA, which are non-GAAP measures, as additional measurements to enhance the understanding of our operating performance.

We believe that EBITDA, considered along with net earnings (loss), is a relevant indicator of trends relating to our operating performance and provides management and investors with additional information for comparison of our operating results to the operating results of other companies.

Adjusted net earnings (loss) and adjusted net earnings (loss) per diluted share are non-GAAP measures that exclude the effects of items that include: debt extinguishment, restructuring and other charges, asset impairment charges, Big River Steel - acquisition-related items, (gains) losses on assets sold & previously held investments, gain on sale of Transtar, net reversal of tax valuation allowance, pension de-risking, environmental remediation charge and other items (Adjustment Items). Adjusted EBITDA is also a non-GAAP measure that excludes the effects of certain Adjustment Items. We present adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA to enhance the understanding of our ongoing operating performance and established trends affecting our core operations by excluding the effects of events that can obscure underlying trends. U. S. Steel's management considers adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA as alternative measures of operating performance and not alternative measures of the Company's liquidity.

U. S. Steel's management considers adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA useful

to investors by facilitating a comparison of our operating performance to the operating performance of our competitors. Additionally, the presentation of adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA provides insight into management's view and assessment of the Company's ongoing operating performance because management does not consider the adjusting items when evaluating the Company's financial performance. Adjusted net earnings (loss), adjusted net earnings (loss) per diluted share and adjusted EBITDA should not be considered a substitute for net earnings (loss), earnings (loss) per diluted share or other financial measures as computed in accordance with U.S. GAAP and is not necessarily comparable to similarly titled measures used by other companies. A condensed consolidated statement of operations (unaudited), condensed consolidated cash flow statement (unaudited), condensed consolidated balance sheet (unaudited) and preliminary supplemental statistics (unaudited) for U. S. Steel are attached.
