Third quarter 2023 adjusted EBITDA is expected to be approximately $550 million. Commenting on third quarter guidance, President and Chief Executive Officer David B. Burritt said, “We are on track to safely deliver a strong third quarter, with each of our operating segments outperforming earlier estimates and contributing to a healthy adjusted EBITDA for the company. A more resilient commercial portfolio and management actions driving higher cost benefits are resulting in better- than-expected performance this quarter. Today’s guidance also reflects the expected impact on third quarter financial results from the United Autoworkers union strike announced earlier this month. Consistent with actions taken in 2022 to balance our melt capacity with our order book, we will temporarily idle blast furnace ‘B’ at Granite City Works and are reallocating volumes to other domestic facilities to efficiently meet customer demand.” Burritt concluded, “We are executing our Best for All strategy as we advance our portfolio of in- flight capital projects on-time and on-budget. The start-up this quarter of the non-grain oriented electrical steel line at Big River Steel continues as planned with first coil expected by the end of the month. Meanwhile, our recently completed pig iron machine at Gary Works is consistently delivering low-cost pig iron to our electric arc furnaces at Big River Steel. Notably, our balance sheet remains strong, as we fund these strategic initiatives while generating cash flow from operations.

Total liquidity is expected to exceed $5 billion for the seventh consecutive quarter.” Third Quarter Adjusted EBITDA Commentary The Flat-Rolled segment’s adjusted EBITDA is expected to be broadly in-line with the second quarter. While spot prices declined sequentially, average selling prices are expected to be slightly higher than previously anticipated on our July earnings call, which is a key driver to the better-than-expected performance in this segment. Additionally, the segment’s diverse customer base has kept its order book resilient. The Mini Mill segment's adjusted EBITDA is expected to be lower than the second quarter. While selling prices moderated during the quarter, segment results are expected to reflect better customer volume performance than previously anticipated and benefit from lower raw material costs. EBITDA margins are expected to remain resilient in the low-to-mid teens. The European segment’s adjusted EBITDA is expected to be lower than the second quarter. Economic headwinds in the region and typical seasonal slowdowns are expected to result in lower average selling prices and a decline in shipment volumes. These headwinds are expected to be partially offset by lower raw material costs in the quarter. The Tubular segment’s adjusted EBITDA is expected to be lower than the second quarter, although remain well above historical levels. Softer market prices and demand as distributor inventory rebalances are expected to be the primary drivers of sequentially weaker EBITDA.

©2023 U. S. Steel. All Rights Reserved NEWS RELEASE www.ussteel.com Note Regarding Non-GAAP Financial Measures We present adjusted net earnings, adjusted net earnings per diluted share, earnings 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, 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, adjusted net earnings per diluted share and adjusted EBITDA are non-GAAP measures that exclude certain charges that are not part of the Company’s core operations such as restructuring or asset impairments (Adjustment Items). We present adjusted net earnings, adjusted net earnings 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, adjusted net earnings per diluted share and adjusted EBITDA as alternative measures of operating performance and not alternative measures of the Company's liquidity and believes these measures are 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 and adjusted EBITDA 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 and adjusted EBITDA 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. ###
