United States Steel Corporation (NYSE:X) reported first quarter 2025 net loss of $116 million, or $0.52 per diluted share. Adjusted net loss was $87 million, or $0.39 per diluted share. This compares to first quarter 2024 net earnings of $171 million, or $0.68 per diluted share. Adjusted net earnings for the first quarter 2024 was $206 million, or $0.82 per diluted share.

Commenting on the Company's first quarter performance, U. S. Steel President and Chief Executive Officer, David B. Burritt said, "Our adjusted EBITDA of $172 million highlights the strength and resilience of our operating performance, despite the seasonally low results driven by annual mining logistics constraints in our North American Flat-Rolled segment and lagging spot prices. Our North American Flat-Rolled segment achieved a solid EBITDA margin of 5%, thanks to our commercial strategy, product mix, and disciplined cost management. We recorded our highest quarter of shipments to date from our Mini Mill segment as Big River 2 ("BR2"), a showcase of American innovation in steelmaking, continues ramping toward full capacity. After accounting for $55 million in ramp-up impact at BR2, Mini Mill EBITDA margins reached 10%. Our European business benefited from higher shipments and strong cost management, while our Tubular segment posted sequential gains on stronger average selling prices. We also expect the first quarter to mark our lowest cash balance for the year, driven primarily by working capital impacts related to mining and the ramp up of BR2."

Burritt added, "We are pleased to see shipments from BR2 continue to rise, with customers praising product quality, especially related to our industry-leading ultra-light gauge hot roll, a first in North America, including for the U.S. commercial construction industry. While markets remain dynamic, our dedicated teams are successfully navigating current volatility through optimizing mix, executing with efficiency, and growing shipment volumes in our Mini Mill segment. Particularly noteworthy is our record-setting safety performance this quarter that speaks volumes about all our mills' operational excellence."

Q2 2025 Outlook

We expect second quarter adjusted EBITDA in the range of $375 million and $425 million. Our North American Flat-Rolled segment results are expected to increase as seasonal constraints in mining logistics ease and higher average steel prices flow through results. However, we do expect a partial offset from lower shipments as a function of planned maintenance activity and outage costs during the quarter. We expect an improvement in Mini Mill segment results, reflecting both an increase in average selling prices and volumes from BR2, even after accounting for approximately $50 million of ramp-up impact at BR2. In Europe, where demand conditions remain tepid, we expect results to be broadly consistent with the first quarter, as higher average selling prices and volumes are expected to be offset by planned seasonal maintenance activities. We expect broadly consistent results in the Tubular segment as the benefits of higher selling prices are partly offset by slightly higher costs. Overall, we expect to deliver positive enterprise free cash flow in the second quarter, as working capital impacts in the first quarter begin to unwind.

We present adjusted net earnings, adjusted net earnings per diluted share, earnings before interest, 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, 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.
