These slides are being provided to assist readers in understanding the acquisition of Big River Steel and other strategic and financial actions by United States Steel Corporation. 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," “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, the consummation of the Big River Steel acquisition (the “Transaction”); potential capital and operational cash improvements; the Company’s plans, objectives, expectations and intentions; the financial condition, results of operations and business of the combined company; the combined company’s products and potential; the Company’s ability to obtain financing for other strategic projects; and the anticipated timing of closing of the Transaction; and statements expressing general views about future 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. The 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 the Company's historical experience and our present expectations or projections. Risks and uncertainties include, among other things, risks related to the satisfaction of the conditions to closing the Transaction in the anticipated timeframe or at all and the possibility that the Transaction does not close; risks related to the ability to realize the anticipated benefits of the Transaction, including the possibility that the expected benefits, synergies and cost savings from the proposed Transaction or the capital and operational cash improvements will not be realized or will not be realized within the expected time period; risks related to the satisfaction of the conditions to closing (including the failure to obtain necessary regulatory approvals) and the risk that the businesses will not be integrated successfully following acquisition; disruption from the Transaction making it more difficult to maintain business and operational relationships; negative effects of the announcement or the consummation of the proposed Transaction on the market price of the Company’s common stock; significant transaction costs; unknown liabilities; the risk of litigation and/or regulatory actions related to the Transaction; other business effects, including the effects of industry, market, economic, political or regulatory conditions; future exchange and interest rates; changes in tax and other laws, regulations, rates and policies; future business combinations or disposals; and competitive developments. All forward-looking statements rely on a number of assumptions, estimates and data concerning future results and events and are subject to a number of uncertainties and other factors that could cause actual results to differ materially from those reflected in such statements. Accordingly, the Company cautions that the forward-looking statements contained herein are qualified by these and other important factors and uncertainties that could cause results to differ materially from those reflected by such statements. For more information on additional potential risk factors, please review the Company’s Annual Report on Form10-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.
