Mountain Valley Pipeline

On June 11, 2020, Mountain Valley Pipeline, LLC (MVP Joint Venture) announced that it is targeting a full in-service date in early 2021 for the Mountain Valley Pipeline (MVP) project. EQM Midstream Partners, LP (EQM) is a 45.7% interest owner and will operate the MVP. In connection with the adjusted targeted in-service date, EQM expects that the total costs for the MVP project may potentially increase by approximately 5% over the project’s $5.4 billion budget (excluding allowance for funds used during construction) primarily due to the need to adapt to complex judicial decisions and regulatory changes.

Through March 31, 2020, based on the MVP project’s $5.4 billion budget, EQM had funded approximately $2.1 billion of EQM’s expected total capital contributions of approximately $2.7 billion. EQM expects that it may be required to fund approximately $175 million related to the potential increase in project costs. During 2020, EQM expects to make total capital contributions of $580 million to $630 million to the MVP Joint Venture for purposes of the MVP, of which approximately $78 million has been contributed to the MVP Joint Venture as of June 11, 2020.

CAUTIONARY STATEMENTS

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. 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, including guidance regarding the cost, timing of regulatory approvals, final design and targeted in-service date of the MVP project; and projected capital contributions. 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 businesses and forward-looking statements include, but are not limited to, those set forth under Item 1A, “Risk Factors” in EQM’s Annual Report on Form 10-K for the year ended December 31, 2019, as updated by Part II, Item 1A, “Risk Factors,” of EQM’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.

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.
