Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. ETRN has based these forward-looking statements on management’s current expectations and assumptions about future events. While ETRN considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory, judicial, construction and other risks and uncertainties, many of which are difficult to predict and are beyond ETRN’s control. The risks and uncertainties that may affect the operations, performance and results of ETRN’s business and forward-looking statements include, but are not limited to, those set forth under Part I, "Item 1A. Risk Factors" in ETRN's Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the SEC), as updated by any risk factors disclosed under Part II, "Item 1A. Risk Factors," of ETRN’s Quarterly Report on Form 10-Q for the three months ended March 31, 2023 filed with the SEC, ETRN's Quarterly Report on Form 10-Q for the three months ended June 30, 2023 to be filed with the SEC and ETRN's subsequent filings. Any forward-looking statement speaks only as of the date on which such statement is made, and ETRN does not intend to correct or update any forward-looking statement, unless required by securities laws, whether as a result of new information, future events or otherwise. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements.
