“In the third quarter, the U. S. Steel team continued to execute with an unwavering commitment to safety as the market recovery took hold,” said U. S. Steel President and Chief Executive Officer David B. Burritt. “Our third quarter results exceeded our guidance and demonstrated the power of the actions we have taken since the onset of COVID-19 with dramatically improved results in our Flat-rolled segment, positive EBITDA in U. S. Steel Europe, and cash from operations of $213 million. We expect to generate positive adjusted EBITDA in the fourth quarter with excitement about our ‘Best of Both’ future.”

Commenting on the Company’s world competitive, “Best of Both” strategy, Burritt said, “I am pleased with the significant progress we have made executing our ‘Best of Both’ strategy so far this year. At the heart of our strategy is the customer, and this month we are celebrating the successful start-up of our electric arc furnace at Fairfield and the one-year anniversary of our investment in Big River Steel. Both of these investments expand our sustainable steel offerings for our customers. It has only been a year and we are confident and enthusiastic that the strategic rationale of our partnership with Big River Steel is being validated. Our teams of leading steel technologists are already proving that sustainable, high-end steel grades previously thought to be impossible for mini mills to produce can indeed be made at Big River with U. S. Steel R&D and know-how.”

We present adjusted net (loss) earnings, adjusted net (loss) earnings per diluted share, (loss) 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 and segment EBITDA, considered along with net (loss) earnings and segment (loss) earnings before interest and income taxes, are relevant indicators of trends relating to our operating performance and provide management and investors with additional information for comparison of our operating results to the operating results of other companies.

Adjusted net (loss) earnings and adjusted net (loss) earnings per diluted share are non-GAAP measures that exclude the effects of items such as the asset impairment charge, restructuring and other charges, the gain on previously held investment in UPI, the Tubular inventory impairment, the December 24, 2018 Clairton coke making facility fire, the Big River Steel options mark to market and the FIN 48 reserve that are not part of the Company's core operations (Adjustment Items). Adjusted EBITDA is also a non-GAAP measure that excludes the financial effects of the Adjustment Items. We present adjusted net (loss) earnings, adjusted net (loss) 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 Adjustment Items. U. S. Steel's management considers adjusted net (loss) earnings, adjusted net (loss) earnings 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 (loss) earnings, adjusted net (loss) earnings 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 (loss) earnings, adjusted net (loss) 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 (loss) earnings, adjusted net (loss) earnings per diluted share and adjusted EBITDA should not be considered a substitute for net (loss) earnings, (loss) earnings 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.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

    This release 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, 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, U. S. Steel's future ability or plans to take ownership of the Big River Steel joint venture as a wholly owned subsidiary, 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, 2019, our Quarterly Reports on Form 10-Q 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.
