NEWS RELEASE

FOR IMMEDIATE RELEASE:

United States Steel Corporation Reports Third Quarter 2024 Results

•Third quarter 2024 net earnings of $119 million, or $0.48 per diluted share.

•Third quarter 2024 adjusted net earnings of $140 million, or $0.56 per diluted share.

•Third quarter 2024 adjusted EBITDA of $319 million.

PITTSBURGH, October 31, 2024 – United States Steel Corporation (NYSE: X) reported third quarter 2024 net earnings of $119 million, or $0.48 per diluted share. Adjusted net earnings was $140 million, or $0.56 per diluted share. This compares to third quarter 2023 net earnings of $299 million, or $1.20 per diluted share. Adjusted net earnings for the third quarter 2023 was $350 million, or $1.40 per diluted share.

Commenting on the Company’s third quarter performance, U. S. Steel President and Chief Executive Officer, David B. Burritt said, “Third quarter adjusted EBITDA of $319 million demonstrated resilience in our business model despite the weaker average selling prices experienced across our operating segments. The North American Flat-Rolled segment continued to benefit from a strong commercial strategy that leveraged a diverse product mix and a purposeful increase in contracted volumes across the end markets we serve. Our Mini Mill segment, which was impacted by softening market pricing, delivered 11% EBITDA margins when adjusting for $40 million in one-time start-up costs for strategic projects. USSE earnings benefited from a one-time favorable adjustment related to CO2 allocations, which offset pressures from a challenging demand environment in Europe. Tubular earnings were weaker in the third quarter, as expected, reflecting lower benchmark prices.”

Commenting on the Company’s strategic initiatives, Burritt continued, “We are very pleased to announce that we achieved first coil at Big River 2 (“BR2”), with the Big River team expecting to begin shipments to customers during the fourth quarter. We are excited to highlight photos of BR2 in the investor presentation posted today on our website. Congratulations to the Big River team on safely delivering over $4 billion of growth capital investments, including the non-grain oriented (“NGO”) electrical steel line and the dual Galvalume® / Galvanized coating line. Coupled with our enhanced commercial strategy and recent investments

News Release

made in the North American Flat Rolled segment, we look forward to building upon our more resilient earnings with increasing free cash flow.”

Commenting on the Company’s transaction with Nippon Steel Corporation, Burritt noted, “We continue to work towards closing by year-end. Importantly, in September, the Board of Arbitration ruled in favor of U. S. Steel under our basic labor agreement. We are also pleased to see additional commitments from Nippon Steel, which will build upon the existing benefits including the transfer of technologies and further innovations from Nippon Steel's $500 million annual R&D spending, to further strengthen the merits of the transaction. We look forward to delivering these benefits to all of our stakeholders, especially to our hardworking men and women in the Mon Valley and Gary plants, where Nippon Steel has committed to invest at least $1.3 billion, increasing the total capital commitment to at least $2.7 billion."

Q4 2024 Outlook

We expect fourth quarter adjusted EBITDA in the range of $225 million and $275 million. Our North American Flat-Rolled segment results should decrease slightly, driven largely by lower lagging average selling price expectations for the quarter. We expect an improvement in Mini Mill segment results, even after accounting for $25 million of related start-up and one-time construction costs at BR2, reflecting an expected improvement in average selling prices. In Europe, results are expected to be lower given the absence of the positive CO2 allocations and weak underlying demand and pricing conditions. Our Tubular segment results should be largely consistent with the third quarter.

News Release

We present adjusted net earnings, adjusted net earnings per diluted share, 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 and adjusted net earnings per diluted share are non-GAAP measures that exclude the effects of items that include: restructuring and other charges, stock-based compensation expense, asset impairment charges, VEBA asset surplus adjustment, environmental remediation charges, strategic alternatives review process costs, Granite City idling costs, tax impact of adjusted items and other charges, net (Adjustment Items). Adjusted EBITDA and adjusted EBITDA margins are also non-GAAP measures that exclude the effects of certain Adjustment Items. We present adjusted net earnings, adjusted net earnings per diluted share, 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 net earnings per diluted share, 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 net earnings per diluted share, 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 net earnings per diluted share, 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 net earnings per diluted share, adjusted EBITDA, and adjusted EBITDA margin should not be considered a substitute for net earnings, earnings per diluted share or other financial measures as computed in accordance with U.S. GAAP and are 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 provide further insight into the Company's overall utilization of cash. 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.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This release contains information regarding the Company and Nippon Steel Corporation ("NSC") that may constitute “forward-looking statements,” as that term is defined under the Private Securities Litigation Reform Act of 1995 and other securities laws, that are subject to risks and uncertainties.

1 EARNINGS PRESENTATION THIRD QUARTER 2024 October 31, 2024

2 FORWARD-LOOKING STATEMENTS This presentation contains information regarding the Company and Nippon Steel Corporation (“NSC”) that may constitute “forward-looking statements,” as that term is defined under the Private Securities Litigation Reform Act of 1995 and other securities laws, that are subject to risks and uncertainties. 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, statements expressing general views about future operating or financial results, operating or financial performance, trends, events or developments that we expect or anticipate will occur in the future, anticipated cost savings, potential capital and operational cash improvements and changes in the global economic environment, anticipated capital expenditures, the construction or operation of new or existing facilities or capabilities and the costs associated with such matters, statements regarding our greenhouse gas emissions reduction goals, as well as statements regarding the proposed transaction between the Company and NSC. 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 future goals, plans and expectations about our prospects for the future and other events, many of which, by their nature, are inherently uncertain and outside of the Company’s or NSC’s control. It is possible that the Company’s or NSC’s actual results and financial condition may differ, possibly materially, from the anticipated results and financial condition indicated in these forward- looking statements. Management of the Company 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. In addition, forward looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from the Company’s or NSC’s historical experience and our present expectations or projections. Risks and uncertainties include without limitation: the ability of the parties to consummate the proposed transaction between the Company and NSC, on a timely basis or at all; the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the proposed transaction; the occurrence of any event, change or other circumstances that could give rise to the termination of the definitive agreement and plan of merger relating to the proposed transaction (the “Merger Agreement”); the risk that the parties to the Merger Agreement may not be able to satisfy the conditions to the proposed transaction in a timely manner or at all; risks related to disruption of management time from ongoing business operations due to the proposed transaction; certain restrictions during the pendency of the proposed transaction that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the Company’s common stock; the risk of any unexpected costs or expenses resulting from the proposed transaction; the risk of any litigation relating to the proposed transaction; the risk that the proposed transaction and its announcement could have an adverse effect on the ability of the Company or NSC to retain customers and retain and hire key personnel and maintain relationships with customers, suppliers, employees, stockholders and other business relationships and on its operating results and business generally; and the risk the pending proposed transaction could distract management of the Company. The Company directs readers to its Form 10-K for the year ended December 31, 2023 and Quarterly Report on Form 10-Q for the quarter ended June 30, 2024, and the other documents it files with the SEC for other risks associated with the Company’s future performance. These documents contain and identify important factors that could cause actual results to differ materially from those contained in the forward-looking statements. All information in this presentation is as of the date above. The Company does not undertake any duty to update any forward-looking statement to conform the statement to actual results or changes in the Company’s expectations whether as a result of new information, future events or otherwise, except as required by law.

3 EXPLANATION OF USE OF NON-GAAP MEASURES We present adjusted net earnings, adjusted net earnings margin, adjusted net earnings per diluted share, earnings before interest, income taxes, depreciation and amortization (EBITDA), adjusted EBITDA, adjusted EBITDA margin and adjusted profit 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 and adjusted net earnings per diluted share are non-GAAP measures that exclude the effects of items that include: asset impairment charges, restructuring and other charges, stock-based compensation expense, VEBA asset surplus adjustment, environmental remediation charges, strategic alternatives review process costs, Granite City idling costs, tax impact of adjusted items and other changes, net (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 net earnings per diluted share, adjusted EBITDA, adjusted EBITDA margin and adjusted profit 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 net earnings per diluted share, adjusted EBITDA, adjusted EBITDA margin and adjusted profit 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 net earnings per diluted share, adjusted EBITDA, adjusted EBITDA margin and adjusted profit 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 net earnings per diluted share, adjusted EBITDA, adjusted EBITDA margin and adjusted profit 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 net earnings per diluted share, adjusted EBITDA, adjusted EBITDA margin and adjusted profit margin should not be considered a substitute for net earnings or other financial measures as computed in accordance with U.S. GAAP and are not necessarily comparable to similarly titled measures used by other companies. 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.
