Cautionary Statement Regarding Forward-Looking Information

Disclosures in this Current Report contain certain forward-looking statements within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act. Statements that do not relate strictly to historical or current facts are forward-looking. Words such as “could,” “will,” “may,” “assume,” “forecast,” “position,” “predict,” “strategy,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” “budget,” “potential,” or “continue,” and similar expressions are used to identify forward-looking statements. Without limiting the generality of the foregoing, forward-looking statements contained in this Current Report specifically include the expectations of plans, strategies, objectives and growth and anticipated financial and operational performance of EQM and its affiliates. These statements involve risks and uncertainties that could cause actual results to differ materially from projected results.

Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. EQM has based these forward-looking statements on current expectations and assumptions about future events. While EQM considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks and uncertainties, many of which are difficult to predict and beyond EQM’s control. The risks and uncertainties that may affect the operations, performance and results of EQM’s business and forward-looking statements include, but are not limited to, those set forth in EQM’s publicly filed reports with the Securities and Exchange Commission (the SEC), including those set forth under Item 1A, “Risk Factors” of EQM’s Form 10-K for the year ended December 31, 2019.

All forward-looking statements speak only as of the date they are made and are based on information available at that time. EQM assumes no obligation to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements were made or to reflect the occurrence of unanticipated events except as required by federal securities laws. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements.
