2 FORWARD-LOOKING STATEMENTS These slides are being provided to assist readers in understanding the results of operations, financial condition and cash flows of ϳԹ as of and for the third quarter 2023. Financial results as of and for the periods ended September 30, 2023 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,” “plan,” “goal,” “future,” “will,” "may" and similar expressions or by using future dates in connection with any discussion of, among other things, the construction or operation of new or existing facilities or operating capabilities, the timing, size and form of share repurchase transactions, operating or financial 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 the global economic environment, including supply and demand conditions, inflation, interest rates, supply chain disruptions and changes in prices for our products, international trade duties and other aspects of international trade policy, statements regarding our future strategies, products and innovations, statements regarding our greenhouse gas emissions reduction goals, statements regarding existing or new regulations 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 include all statements that are not historical facts, but instead represent only the Company’s beliefs regarding goals, plans and expectations about our prospects for the future and other future events, many of which, by their nature, are inherently uncertain, qualified by important factors 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, whether the objectives of the Company’s previously announced strategic alternatives review process will be achieved; the terms, structure, timing, benefits and costs of any strategic transaction; and whether any such transaction will be consummated at all; the risk that the strategic alternatives review process and its announcement could have an adverse effect on the ability of the Company to retain customers and retain and hire key personnel and maintain relationships with customers, suppliers, employees, shareholders and other business relationships and on its operating results and business generally; the risk that the strategic alternatives review process could divert the attention and time of the Company’s management, the risk of any unexpected costs or expenses resulting from the strategic alternatives review process; the risk of any litigation relating to the strategic alternatives review process; and the risks and uncertainties described in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and those described from time to time in our future reports filed with the Securities and Exchange Commission. References to (i) "U. S. Steel," "the Company," "we," "us," and "our" refer to ϳԹ and its consolidated subsidiaries unless otherwise indicated by the context and (ii) “Big River Steel” refer to Big River Steel Holdings LLC and its direct and indirect subsidiaries unless otherwise indicated by the context.


 
3 EXPLANATION OF USE OF NON-GAAP MEASURES We present adjusted net earnings, earnings before interest, income taxes, depreciation and amortization (EBITDA), adjusted EBITDA and adjusted EBITDA margin, 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, 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 is a non-GAAP measure that exclude the effects of items that include: debt extinguishment, asset impairment charges, restructuring and other charges, stock-based compensation expense, VEBA asset surplus adjustment, gains on assets sold and previously held investments, pension de-risking, United Steelworkers labor agreement signing bonus and related costs, environmental remediation charges, the Company's previously announced strategic alternatives review process, Granite City idling costs, other charges, net and tax impact of adjusted items (Adjustment Items). Adjusted EBITDA and adjusted EBITDA margin are also non-GAAP measures that exclude the effects of certain Adjustment Items. We present adjusted net earnings, adjusted EBITDA and adjusted EBITDA margin 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, adjusted EBITDA and adjusted EBITDA margin as alternative measures of operating performance and not alternative measures of the Company's liquidity. U. S. Steel’s management considers adjusted net earnings, adjusted EBITDA and adjusted EBITDA margin 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, adjusted EBITDA and adjusted EBITDA margin provides insight into management’s view and assessment of the Company’s ongoing operating performance because management does not consider the Adjustment Items when evaluating the Company’s financial performance. Adjusted net earnings, adjusted EBITDA and adjusted EBITDA margin should not be considered a substitute for net earnings 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. We also present free cash flow, a non-GAAP measure of cash generated from operations after any investing activity and investable free cash flow, a non-GAAP measure of cash generated from operations after any investing activity adjusted for strategic capital expenditures. We believe that free cash flow and investable free cash flow provides further insight into the Company's overall utilization of cash. We also present net debt, a non-GAAP measure calculated as total debt less cash and cash equivalents. We believe net debt is a useful measure in calculating enterprise value. 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.
