The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial information and with the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these unaudited consolidated financial statements include all adjustments (consisting of only normal, recurring adjustments, unless otherwise disclosed in this Quarterly Report on Form 10-Q) necessary for a fair presentation of the financial position of the Company as of June 30, 2024, the results of its operations, and equity for the three and six months ended June 30, 2024 and 2023 and its cash flows for the six months ended June 30, 2024 and 2023. The consolidated balance sheet at December 31, 2023 has been derived from the audited financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2023, which includes all disclosures required by GAAP.

Due to, among other things, the seasonal nature of the Company's utility customer contracts, as well as producers’ well completion activities and varying needs for fresh and produced water (which are primarily driven by horizontal lateral lengths and the number of completion stages per well), the interim statements for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.

For further information, refer to the Company's consolidated financial statements and related notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, as well as Part I, "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" contained herein.

Recently Issued Accounting Standards.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides improvements to reportable segment disclosures and is intended to enhance the disclosures regarding significant segment expenses. The guidance is applicable to all public entities that are required to report segment information in accordance with Topic 280 and is to be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the potential impact of adopting this standard on its financial statements and related disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures, which provides improvements to income tax disclosures and is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The guidance is applicable to all public entities required to report income taxes in accordance with ASC 740 and should be applied prospectively, but retrospective application is permitted. The standard requires disaggregated information about a reporting entity’s effective tax rate reconciliation, information on income taxes paid, and various other disclosure changes. The Company is currently evaluating the potential impact of adopting this standard on its financial statements and related disclosures.

2. Proposed EQT Transaction

Proposed EQT Transaction. On March 10, 2024, the Company, EQT Corporation (Parent), Humpty Merger Sub Inc., an indirect wholly owned subsidiary of Parent (Merger Sub), and Humpty Merger Sub LLC, an indirect wholly owned subsidiary of Parent (LLC Sub), entered into an Agreement and Plan of Merger (the Merger Agreement), pursuant to which, among other things, Merger Sub will merge with and into the Company (the First Merger), with the Company surviving the First Merger as an indirect wholly owned subsidiary of Parent (the First Step Surviving Corporation) and, as the second step in a single integrated transaction, the First Step Surviving Corporation will merge with and into LLC Sub (the Second Merger and,

Table of Contents

together with the First Merger, the Mergers), with LLC Sub surviving the Second Merger as an indirect wholly owned subsidiary of Parent (the transactions contemplated by the Merger Agreement, the EQT Transaction).

Under the terms of the Merger Agreement, and subject to the satisfaction or waiver of certain conditions therein, at the effective time of the First Merger (the Effective Time), (i) each share of common stock, no par value per share, of Equitrans Midstream Corporation (Equitrans Midstream common stock) issued and outstanding immediately prior to the Effective Time (excluding any excluded shares) will be converted automatically at the Effective Time into the right to receive 0.3504 (the Exchange Ratio) fully-paid and nonassessable shares of common stock of Parent, no par value per share (EQT Shares) and (ii) each Equitrans Midstream Corporation Series A Perpetual Convertible Preferred Share, no par value (Equitrans Midstream Preferred Share), issued and outstanding immediately prior to the Effective Time will be treated in accordance with Section 8 of the Company’s Second Amended and Restated Articles of Incorporation and the procedures set forth in Section 2.5 of the Merger Agreement.

The EQT Transaction is expected to close on July 22, 2024, taking into account, as of the filing of this Quarterly Report on Form 10-Q, the satisfaction in accordance with the terms and conditions of the Merger Agreement of various conditions to closing under the Merger Agreement, including, among others: (i) approval of the Merger Agreement and the Mergers by a majority of the votes cast by holders of Equitrans Midstream common stock and Equitrans Midstream Preferred Shares, with such Equitrans Midstream Preferred Shares treated as Equitrans Midstream common stock on an as-converted basis, voting together as a single class, (ii) approval of the issuance of EQT Shares in connection with the Mergers by a majority of votes cast at a special meeting of holders of EQT Shares, (iii) expiration or termination of (a) all waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the HSR Act) and (b) any commitment to, or agreement with, any governmental entity to delay the consummation of, or not to consummate the transactions contemplated by the Merger Agreement, and (iv) the MVP Joint Venture receiving authorization of the Federal Energy Regulatory Commission (FERC) to place the Mountain Valley Pipeline (MVP) in-service.

The Company recorded approximately $2.0 million and $7.7 million in expenses related to the EQT Transaction during the three and six months ended June 30, 2024, respectively, primarily related to advisor, legal and other transaction-related fees, which are included in transaction costs on the Company's statements of consolidated comprehensive income.

Equitrans Midstream Preferred Shares Redemption. On June 25, 2024, Parent delivered to the Company a written election exercising Parent’s right under the Merger Agreement to cause the Company to purchase and redeem, prior to the Effective Time, all issued and outstanding Equitrans Midstream Preferred Shares in accordance the Company’s Second Amended and Restated Articles of Incorporation. The Company has no obligation to purchase and redeem the Equitrans Midstream Preferred Shares in accordance with the Merger Agreement unless Parent has deposited with the paying agent for such redemption sufficient funds to effect such purchase and redemption, and the deposit of such funds and any instructions and authority to pay such funds to holders of the Equitrans Midstream Preferred Shares in the redemption has occurred at least one hour prior to the consummation of the proposed EQT Transaction. In the event the EQT Transaction will not be consummated, the redemption will not be effected. Subject to the foregoing, the Company expects the purchase and redemption to occur on July 22, 2024 prior to the consummation of the EQT Transaction (or such later date as may be contemplated by virtue of the timing of the consummation of the EQT Transaction).

The Equitrans Midstream Preferred Shares are presented as temporary equity in the mezzanine equity section of the Company’s consolidated balance sheets. As the Equitrans Midstream Preferred Shares were not redeemable or probable of becoming redeemable as of June 30, 2024, adjustment to the carrying amount is not necessary and would only be required if the Equitrans Midstream Preferred Shares are redeemed in accordance with the events described above.

5. Investment in Unconsolidated Entity

The MVP Joint Venture. The Company has an equity method investment in the MVP Joint Venture. The MVP Joint Venture constructed the MVP and is developing the MVP Southgate project, each discussed in more detail below. The Company maintains separate ownership interests in each of the MVP and the MVP Southgate project and is the operator of the MVP and expects to operate the MVP Southgate project.

Mountain Valley Pipeline. The MVP Joint Venture received authorization of the FERC on June 11, 2024 to place the MVP, a 303-mile natural gas interstate pipeline that spans from northern West Virginia to southern Virginia, in service and the MVP entered service and became available for interruptible or short-term firm transportation service on June 14, 2024. The Company owned a 49.0% interest in the MVP as of June 30, 2024.

MVP and MVP-related long-term firm capacity obligations commenced on July 1, 2024. Upon commencement of the MVP long-term firm capacity obligations on July 1, 2024, the MVP Joint Venture is no longer a variable interest entity of the Company because it has sufficient equity to finance its activities.

The MVP Joint Venture has continued to undertake certain restoration efforts in respect of the MVP since the in-service date and the Company is targeting a total project cost of approximately $7.9 billion (excluding allowance for funds used during

Table of Contents

construction (AFUDC) and which does not reflect general contingency). Based on such total project cost estimate, the Company's equity ownership in the MVP is expected to progressively increase from approximately 49.0% to approximately 49.2%.

Pursuant to the EQT Global GGA and given MVP full in-service occurred in 2024, MVC step ups and gathering fee rates are to be set forth in an amendment to the EQT Global GGA. The step ups and rates would become effective as of July 1, 2024 in accordance with the terms of the EQT Global GGA. The amendment, which reflects the step ups and rates assumed by the Company for purposes of the EQT Global GGA, has been negotiated, but not yet executed, with EQT as of the filing of this Quarterly Report on Form 10-Q.

The Company has a negative basis difference between the carrying value of its equity method investment and its proportionate share of MVP's net assets, which are entirely attributable to fixed assets. The basis difference is accreted over the life of the fixed assets and reflected as income in equity income on the Company's statements of consolidated comprehensive income.

In June 2024, the MVP Joint Venture issued a capital call notice for the funding of the MVP project to MVP Holdco, LLC (MVP Holdco) for $73.9 million, which was paid in July 2024. The capital contributions payable and the corresponding increase to the investment balance are reflected on the consolidated balance sheet as of June 30, 2024.

Pursuant to the MVP Joint Venture's limited liability company agreement, MVP Holdco was obligated to provide performance assurances in respect of the MVP project through in-service, which could take the form of a guarantee from EQM (provided that EQM's debt is rated as investment grade in accordance with the requirements of the MVP Joint Venture's limited liability company agreement), a letter of credit or cash collateral, in favor of the MVP Joint Venture to provide assurance as to the funding of MVP Holdco's proportionate share of the construction budget for the MVP project through in-service. On June 28, 2024, following MVP in-service, the $104.7 million letter of credit with respect to the MVP project was terminated.

The Company's ownership interest in the MVP Joint Venture related to the MVP project is significant for the three and six months ended June 30, 2024 as defined by the SEC's Regulation S-X Rule 1-02(w). Accordingly, as required by Regulation S-X Rule 3-09, the following tables summarize the condensed financial statements of the MVP Joint Venture in relation to the MVP project.

MVP Southgate Project. In April 2018, the MVP Joint Venture announced the MVP Southgate project (MVP Southgate) as a contemplated interstate pipeline that was approved by the United States FERC and designed to extend approximately 75 miles from the MVP in Pittsylvania County, Virginia to new delivery points in Rockingham and Alamance Counties, North Carolina using 24-inch and 16-inch diameter pipe.

In late December 2023, following completion of its negotiations with each of Public Service Company of North Carolina, Inc. (PSNC) and Duke Energy Carolinas, LLC (Duke), the MVP Joint Venture entered into precedent agreements with each of PSNC and Duke. The precedent agreements contemplate an amended project (in lieu of the original project) and, among other things, describe certain conditions precedent to the parties' respective obligations regarding MVP Southgate. The amended project would extend approximately 31 miles from the terminus of the MVP in Pittsylvania County, Virginia to planned new delivery points in Rockingham County, North Carolina using 30-inch diameter pipe.

The Company is expected to operate the MVP Southgate pipeline and owned a 47.2% interest in the MVP Southgate project as of June 30, 2024. The targeted completion timing for the project is June 2028.

Pursuant to the MVP Joint Venture's limited liability company agreement, MVP Holdco is obligated to provide performance assurances in respect of MVP Southgate, which performance assurances may take the form of a guarantee from EQM (provided that EQM's debt is rated as investment grade in accordance with the requirements of the MVP Joint Venture's limited liability company agreement), a letter of credit or cash collateral. On April 6, 2023, EQM’s $14.2 million letter of credit with respect to the MVP Southgate project was terminated, following the determination to temporarily defer partners’ obligations to post performance assurances with respect to the MVP Southgate project, which may be reinstated upon further developments. Upon the FERC’s initial release to begin construction of the MVP Southgate project, the Company will be obligated to deliver an allowable form of performance assurance in an amount equal to 33% of MVP Holdco’s proportionate share of the remaining capital obligations under the applicable construction budget.

6. Share-based Compensation Plans

In December 2021, the Company granted a special, one-time, performance award program designed to reward all employees should the Company’s most complex and strategically significant project, the MVP project, be placed in-service, subject to continued service through the applicable payment date (the MVP PSU Program). The achievement of the MVP Joint Venture being authorized by the FERC to commence service on the MVP represented a performance condition as defined by ASC 718, Share-based Compensation. During the second quarter of 2024, the MVP Joint Venture was authorized by the FERC to commence service on the MVP. As such, the performance condition of the MVP PSU Program was achieved and the award vested and was paid in Company common stock on June 28, 2024. Certain shares of the MVP PSU Program remain outstanding and are subject to continued service through the first and second anniversaries of the in-service date.

In June 2023, the performance condition associated with the MVP PSU Program awards was deemed to be probable, and the Company recognized compensation cost of approximately $16.8 million that included the cumulative catch-up of approximately $14.1 million to reflect the requisite service period of each award that had been provided to date. As of June 30, 2024, there was approximately $1.7 million of unrecognized compensation cost related to non-vested MVP PSU Program awards that is expected to be recognized over a remaining weighted average vesting term of approximately 1.4 years.

7. Debt

Amended EQM Credit Facility. On February 15, 2024 (the Fifth Amendment Date), EQM entered into an amendment (the Fifth Amendment) to the Third Amended and Restated Credit Agreement, dated as of October 31, 2018 (as amended, supplemented or otherwise modified, the Amended EQM Credit Facility), among EQM, as borrower, Wells Fargo Bank, National Association, as the administrative agent, swing line lender and an L/C issuer, the lenders party thereto from time to time and any other persons party thereto from time to time. The Fifth Amendment, among other things, amended the financial covenant, such that the Consolidated Leverage Ratio (as defined in the Amended EQM Credit Facility) (i) as of March 31, 2024, could not exceed 6.00 to 1.00, (ii) as of June 30, 2024, could not exceed 6.25 to 1.00, (iii) as of September 30, 2024, cannot exceed 5.85 to 1.00 and (iv) as of the end of each fiscal quarter thereafter, cannot exceed 5.50 to 1.00. EQM has or, as applicable, will have aggregate commitments available under the Amended EQM Credit Facility of approximately $1.55 billion prior to April 30, 2025, and approximately $1.45 billion on and after April 30, 2025 and prior to April 30, 2026. For the avoidance of doubt, any reference to the Amended EQM Credit Facility as of any particular date shall mean the Amended EQM Credit Facility as in effect on such date.

As of June 30, 2024, EQM had $655 million of borrowings and approximately $1.0 million of letters of credit outstanding under the Amended EQM Credit Facility. As of December 31, 2023, EQM had $915 million of borrowings and approximately $105.8 million of letters of credit outstanding under the Amended EQM Credit Facility. Taking into account the maximum Consolidated Leverage Ratio applicable under the Amended EQM Credit Facility that, as of June 30, 2024, could not exceed 6.25 to 1.00, EQM had the ability to borrow approximately $0.5 billion under the Amended EQM Credit Facility as of June 30, 2024. The Company believes that its cash on hand, future cash generated from operations and future cash received from potential distributions from the MVP Joint Venture, including as a result of potential financing at the MVP Joint Venture, together with available borrowing capacity under its subsidiaries' credit facilities and its access to banking and capital markets, will provide adequate resources to fund its short-term and long-term capital, operating and financing needs.

During the three and six months ended June 30, 2024, the maximum outstanding borrowings at any time were approximately $655 million and $1,055 million, respectively, the average daily balances were approximately $545 million and $690 million, respectively, and the weighted average annual interest rate was approximately 8.3%. For the three and six months ended June 30, 2024, commitment fees of $1.2 million and $1.9 million, respectively, were paid to maintain credit availability under the Amended EQM Credit Facility. During the three and six months ended June 30, 2023, the maximum outstanding borrowings at any time were approximately $255 million and $315 million, respectively, the average daily balances were approximately $191 million and $225 million, respectively, and the weighted average annual interest rates were approximately 7.9% and 7.7%, respectively. For the three and six months ended June 30, 2023, commitment fees of $2.3 million and $4.4 million, respectively, were paid to maintain credit availability under the Amended EQM Credit Facility. As of June 30, 2024 and December 31, 2023, no term loans were outstanding under the Amended EQM Credit Facility.

The Amended EQM Facility contains negative covenants that, among other things, limit restricted payments, the incurrence of debt, dispositions, mergers and other fundamental changes, and transactions with affiliates, in each case and as applicable, subject to certain specified exceptions. In addition, the Amended EQM Credit Facility contains certain specified events of default such as insolvency, nonpayment of scheduled principal or interest obligations, change of control and cross-default related to the acceleration or default of certain other financial obligations.

Eureka Credit Facility. Eureka has a $400 million senior secured revolving credit facility with Sumitomo Mitsui Banking Corporation, as administrative agent, the lenders party thereto from time to time and any other persons party thereto from time to time (the 2021 Eureka Credit Facility) that matures in November 2025.

As of June 30, 2024, and December 31, 2023, Eureka had $330 million and $315 million, respectively, of borrowings outstanding under the 2021 Eureka Credit Facility. For the three and six months ended June 30, 2024, the maximum amount of outstanding borrowings under the 2021 Eureka Credit Facility at any time were approximately $330 million, the average daily balances were approximately $330 million and $326 million, respectively, and Eureka incurred interest at a weighted average annual interest rate of approximately 8.3%. For the three and six months ended June 30, 2024, commitment fees of $0.1 million and $0.2 million, respectively, were paid to maintain credit availability under the 2021 Eureka Credit Facility. For the three and six months ended June 30, 2023, the maximum amount of outstanding borrowings under the 2021 Eureka Credit Facility at any time were approximately $315 million, the average daily balances were approximately $309 million and $303 million, respectively, and Eureka incurred interest at weighted average annual interest rates of approximately 7.7% and 7.4%, respectively. For the three and six months ended June 30, 2023, commitment fees of $0.1 million and $0.2 million, respectively, were paid to maintain credit availability under the 2021 Eureka Credit Facility.

The 2021 Eureka Credit Facility contains negative covenants that, among other things, limit restricted payments, the incurrence of debt, dispositions, mergers and other fundamental changes, and transactions with affiliates, in each case and as applicable, subject to certain specified exceptions. In addition, the 2021 Eureka Credit Facility contains certain specified events of default

such as insolvency, nonpayment of scheduled principal or interest obligations, loss and failure to replace certain material contracts, change of control and cross-default related to the acceleration or default of certain other financial obligations.

2024 Senior Notes. On February 26, 2024, EQM completed a private offering of $600 million in aggregate principal amount of new 6.375% senior notes due 2029 (the 2024 Senior Notes) and received net proceeds from the offering of approximately $590.6 million inclusive of a discount of approximately $7.5 million and debt issuance costs of approximately $1.9 million. EQM used the net proceeds from the 2024 Senior Notes offering to repay certain outstanding indebtedness, including borrowings under the Amended EQM Credit Facility, and for general partnership purposes.

The 2024 Senior Notes were issued under and are governed by an indenture, dated February 26, 2024 (the 2024 Indenture), between EQM and U.S. Bank Trust Company, National Association, as trustee (the Trustee). The 2024 Indenture contains covenants that limit EQM’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of EQM’s assets. The 2024 Senior Notes will mature on April 1, 2029 and interest on the 2024 Senior Notes is payable semi-annually in arrears on April 1 and October 1 of each year, commencing on October 1, 2024.

The 2024 Senior Notes are unsecured and rank equally in right of payment with all of EQM’s existing and future senior indebtedness. The 2024 Senior Notes are senior in right of payment to any of EQM’s future indebtedness that are, by their terms, expressly subordinated in right of payment to the 2024 Senior Notes. The 2024 Senior Notes are effectively subordinated to EQM’s future secured indebtedness, if any, to the extent of the value of the assets securing such indebtedness, and structurally subordinated to all existing and future obligations, including trade payables, of EQM’s subsidiaries, other than any subsidiaries that may guarantee the Notes in the future.

EQM may, at its option, redeem some or all of the 2024 Senior Notes, in whole or in part, at any time prior to their maturity at the applicable redemption price as set forth in the Indenture.

Upon the occurrence of a Change of Control Triggering Event (as defined in the 2024 Indenture), EQM may be required to offer to purchase the 2024 Senior Notes at a purchase price equal to 101% of the aggregate principal amount of the 2024 Senior Notes repurchased, plus accrued and unpaid interest, if any, on the 2024 Senior Notes repurchased, to, but excluding, the date of settlement, subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of settlement.

The 2024 Indenture contains certain events of default (each an Event of Default), including the following: (1) default in the payment of interest on such 2024 Senior Notes when due that continues for 30 days; (2) default in the payment of principal of or premium, if any, on any such 2024 Senior Notes when due, whether at its stated maturity, upon redemption or otherwise; (3) failure by EQM or any subsidiary guarantor, if any, to comply for 90 days with the other agreements with respect to such 2024 Senior Notes contained in the 2024 Indenture after written notice by the Trustee or by the holders of at least 25% in principal amount of the outstanding 2024 Senior Notes; (4) certain events of bankruptcy, insolvency or reorganization of EQM or any subsidiary guarantor, if any, that is one of EQM’s Significant Subsidiaries (as defined in the 2024 Indenture); and (5) if such 2024 Senior Notes are guaranteed by a subsidiary guarantor that is one of EQM’s Significant Subsidiaries, (a) the guarantee of that subsidiary guarantor ceases to be in full force and effect, except as otherwise provided in the 2024 Indenture; (b) the guarantee of that subsidiary guarantor is declared null and void in a judicial proceeding; or (c) such subsidiary guarantor denies or disaffirms its obligations under the 2024 Indenture or its guarantee.

If an Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding 2024 Senior Notes may declare the principal of and all accrued and unpaid interest on such 2024 Senior Notes to be immediately due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization occurs, the principal of and interest on the 2024 Senior Notes will become immediately due and payable without any action on the part of the Trustee or any holders of the 2024 Senior Notes.

2023 Senior Notes Redemption. On June 21, 2023 (the Redemption Date), EQM redeemed in full its remaining outstanding 4.75% Senior Notes due 2023 (the 2023 Notes) in the aggregate principal amount of $98.9 million, pursuant to the Indenture, dated as of August 1, 2014, by and between EQM, the subsidiary guarantors party thereto and The Bank of New York Mellon Trust Company, N.A. (BNYMTC), as trustee, as supplemented by that certain Third Supplemental Indenture, dated as of June 25, 2018, by and between the EQM and BNYMTC, at a redemption price equal to 100% of the principal amount of the 2023 Notes, plus accrued and unpaid interest to, but not including, the Redemption Date. Upon the redemption by EQM of the 2023 Notes, the Third Supplemental Indenture was discharged and ceased to be of further effect except as to rights thereunder. EQM utilized cash on hand to effect payment of the redemption on the Redemption Date.

As of June 30, 2024, EQM and Eureka were in compliance with all debt provisions and covenants.

8. Fair Value Measurements

Assets Measured at Fair Value on a Recurring Basis. The Company records derivative instruments at fair value on a gross basis in its consolidated balance sheets. The Company, EQT and certain affiliates of EQT have a Gas Gathering and Compression Agreement dated February 26, 2020 (as amended, the "EQT Global GGA") which provides, among other things, for potential cash bonus payments payable by EQT to the Company during the period that began on July 1, 2024 through the calendar quarter ending December 31, 2024 (the Henry Hub cash bonus payment provision). The potential cash bonus payments are conditioned upon the quarterly average of certain Henry Hub natural gas prices exceeding certain price thresholds. The Henry Hub cash bonus payment provision is accounted for as a derivative instrument and recorded at its estimated fair value using a Monte Carlo simulation model. Significant inputs used in the fair value measurement include NYMEX Henry Hub natural gas futures prices as of the date of valuation, probability-weighted assumptions regarding MVP project completion (prior to in-service), the actual MVP in-service date, risk-free interest rates based on U.S. Treasury rates, expected volatility of NYMEX Henry Hub natural gas futures prices and an estimated credit spread of EQT. The probability-weighted assumptions regarding MVP project completion utilizing internally developed methodologies (prior to in-service), and the expected volatility of NYMEX Henry Hub natural gas futures prices, used in the valuation methodology represent significant unobservable inputs causing the Henry Hub cash bonus payment provision to be designated as a Level 3 fair value measurement. An expected average volatility of approximately 55.0% was utilized in the valuation model, which is based on market-quoted volatilities of relevant NYMEX Henry Hub natural gas forward prices.

As of June 30, 2024 and December 31, 2023, the fair values of the Henry Hub cash bonus payment provision were $23.0 million and $24.5 million, respectively, which were recorded in other current assets on the Company's consolidated balance sheets. During the three and six months ended June 30, 2024, the Company recognized a gain of $3.2 million and a loss of $1.5 million, respectively, and during the three and six months ended June 30, 2023 the Company recognized gains of $19.4 million and $10.9 million, respectively, representing the change in estimated fair value of the derivative instrument during the respective periods and are recorded in other income (expense), net on the Company's statements of consolidated comprehensive income.

Other Financial Instruments. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short maturity of the instruments. The carrying values of borrowings under the Amended EQM Credit Facility and the 2021 Eureka Credit Facility approximate fair value as the interest rates are based on prevailing market rates. As EQM's borrowings under its senior notes are not actively traded, their fair values are estimated using an income approach model that applies a discount rate based on prevailing market rates for debt with similar remaining time-to-maturity and credit risk; as such, their fair values are Level 2 fair value measurements. As of June 30, 2024 and December 31, 2023, the estimated fair values of EQM's senior notes were approximately $6,916.8 million and $6,334.3 million, respectively, and the carrying values of EQM's senior notes were approximately $6,943.2 million and $6,346.4 million, respectively. The fair value of the preferred interest that the Company has in EQT Energy Supply, LLC (EES), a subsidiary of EQT (the Preferred Interest) is a Level 3 fair value measurement and is estimated using an income approach model that applies a market-based discount rate. As of June 30, 2024, and December 31, 2023, the estimated fair values of the Preferred Interest were approximately $86.3 million and $90.7 million, respectively, and the carrying values of the Preferred Interest were approximately $85.4 million and $88.5 million, respectively.

9. Earnings Per Share

The Company excluded 30,059 and 30,111 (in thousands) of weighted average anti-dilutive securities related to the Equitrans Midstream Preferred Shares and stock-based compensation awards from the computation of diluted weighted average common shares outstanding for the three and six months ended June 30, 2024. The Company excluded 31,125 and 32,506 (in thousands) of weighted average anti-dilutive securities related to the Equitrans Midstream Preferred Shares and stock-based compensation awards from the computation of diluted weighted average common shares outstanding for the three and six months ended June 30, 2023.

The Company grants Equitrans Midstream phantom units to non-employee directors that will be paid in Equitrans Midstream common stock upon the director's termination of service from the Company's Board of Directors. As there are no remaining service, performance or market conditions related to these awards, 901 and 871 (in thousands) Equitrans Midstream phantom units were included in the computation of basic and diluted weighted average common shares outstanding for the three and six months ended June 30, 2024, respectively and 745 and 674 (in thousands) Equitrans Midstream phantom units were included in the computation of basic and diluted weighted average common shares outstanding for the three and six months ended June 30, 2023, respectively.

10. Income Taxes

Table of Contents

The Company's effective tax rate was 9.0% for the three months ended June 30, 2024 compared to 0.7% for the three months ended June 30, 2023. The Company's effective tax rate was 12.6% for the six months ended June 30, 2024 compared to (1.9)% for the six months ended June 30, 2023. The Company calculates the provision for income taxes for interim periods by applying an estimate of the annual effective tax rate for the full fiscal year to "ordinary" income or loss (income (loss) before income taxes excluding unusual or infrequently occurring items) for the periods. The effective tax rate was higher for the three and six months ended June 30, 2024 compared to the three and six months ended June 30, 2023 primarily due to the impact of changes in the valuation allowance that limit tax benefits for the Company's federal and state deferred tax assets and the impact of projected AFUDC - equity from the MVP project. The effective tax rate for the three and six months ended June 30, 2024 and for the three and six months ended June 30, 2023 was lower than the statutory rate primarily due to the impact of changes in valuation allowances that limit tax benefits for the Company’s federal and state deferred tax assets and the impact of projected AFUDC – equity from the MVP project.

For the six months ended June 30, 2024, the Company believes that it is more likely than not that a portion of the benefit from the deferred tax assets related to interest disallowance carryforward under Internal Revenue Code Section 163(j) will not be realized and accordingly, the Company maintains a valuation allowance. For the six months ended June 30, 2024, the Company recorded approximately $20.2 million in income tax benefit related to changes in valuation allowances because of increases in federal and state deferred tax liabilities that are expected to be realized against net operating losses and a portion of the interest disallowance carryforward. As of June 30, 2024 and December 31, 2023, the valuation allowances related to federal and state deferred tax assets were approximately $36.6 million and $56.8 million, respectively.

Executive Overview

Net income attributable to Equitrans Midstream common shareholders was $49.9 million, $0.11 per diluted share, for the three months ended June 30, 2024 compared to $52.6 million, $0.12 per diluted share, for the three months ended June 30, 2023. The decrease resulted primarily from higher net interest expense, lower other income and higher income tax expense, partially offset by higher operating revenues.

Net income attributable to Equitrans Midstream common shareholders was $144.2 million, $0.33 per diluted share, for the six months ended June 30, 2024 compared to $139.7 million, $0.32 per diluted share, for the six months ended June 30, 2023. The increase resulted primarily from higher equity income and higher operating revenues, partially offset by higher net interest expense, higher income tax expense, lower other income and higher operating expenses.

Proposed Acquisition by EQT Corporation. On March 10, 2024, we entered into a definitive agreement to be acquired by EQT. The EQT Transaction is expected to close on July 22, 2024 taking into account, as of the filing of this Quarterly Report on Form 10-Q, the satisfaction in accordance with the terms and conditions of the Merger Agreement of various conditions to closing under the Merger Agreement, including, among others: (i) approval of the Merger Agreement and the Mergers by a majority of the votes cast by holders of Equitrans Midstream common stock and Equitrans Midstream Preferred Shares, with such Equitrans Midstream Preferred Shares treated as Equitrans Midstream common stock on an as-converted basis, voting together as a single class, (ii) approval of the issuance of EQT Shares in connection with the Mergers by a majority of votes cast at a special meeting of holders of EQT Shares, (iii) expiration or termination of (a) all waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the HSR Act) and (b) any commitment to, or agreement with, any governmental entity to delay the consummation of, or not to consummate the transactions contemplated by the Merger Agreement, and (iv) the MVP Joint Venture receiving authorization of the FERC to place the MVP in-service. The Company recorded approximately $2.0 million and $7.7 million in expenses related to the EQT Transaction during the three and six months ended June 30, 2024, respectively, primarily related to advisor, legal and other transaction-related fees.

On June 25, 2024, Parent delivered to the Company a written election exercising Parent’s right under the Merger Agreement to cause the Company to purchase and redeem, prior to the Effective Time, all issued and outstanding Equitrans Midstream Preferred Shares in accordance the Company’s Second Amended and Restated Articles of Incorporation. The Company has no obligation to purchase and redeem the Equitrans Midstream Preferred Shares in accordance with the Merger Agreement unless Parent has deposited with the paying agent for such redemption sufficient funds to effect such purchase and redemption, and the deposit of such funds and any instructions and authority to pay such funds to holders of the Equitrans Midstream Preferred Shares in the redemption has occurred at least one hour prior to the consummation of the proposed EQT Transaction. In the event the EQT Transaction will not be consummated, the redemption will not be effected. Subject to the foregoing, the Company expects the purchase and redemption to occur on July 22, 2024 prior to the consummation of the EQT Transaction (or such later date as may be contemplated by virtue of the timing of the consummation of the EQT Transaction).

Mountain Valley Pipeline and Related Long-Term Firm Capacity. After receiving FERC authorization on June 11, 2024, MVP entered service on June 14, 2024 and became available for interruptible or short-term firm transportation service. MVP and MVP-related long-term firm capacity obligations commenced on July 1, 2024.

The MVP Joint Venture has continued to undertake certain restoration efforts in respect of the MVP since the in-service date. However, project costs were adversely affected by certain factors, including primarily unexpectedly high bids received from contractors for certain restoration work, overall restoration productivity relative to expectations, and unexpected subcontractor costs invoiced for now-completed boring work. Given these costs, the overall declining scope of work as restoration efforts continue, and the Company’s views of other relevant factors, the Company is targeting a total project cost of approximately $7.9 billion (excluding AFUDC). While such targeted total project cost incorporates certain forecasted factors such as potential changes in restoration scope, it does not reflect general contingency for factors which also could affect the total project cost realized, such as weather, unexpected contractor costs and other factors outlined in the "Cautionary Statements" section of this Quarterly Report on Form 10-Q.

The MVP Joint Venture has secured a total of 2.0 Bcf per day of firm capacity commitments at 20-year terms. Additional shippers have expressed interest in the MVP project and the MVP Joint Venture is evaluating an expansion opportunity that could add approximately 0.5 Bcf per day of capacity through the installation of incremental compression. Through June 30, 2024, the Company had funded approximately $4.0 billion to the MVP Joint Venture for the MVP project. Based on the total project cost estimate of approximately $7.9 billion (excluding AFUDC), the Company’s equity ownership in the MVP project is expected to progressively increase from approximately 49.0% to approximately 49.2%.

Additionally, EQT's long-term firm capacity commitments for the Hammerhead pipeline commenced on July 1, 2024. Interruptible volumes from the Company's Hammerhead Gathering agreement with EQT continued up to the full commercial

in-service date of the Hammerhead pipeline of July 1, 2024, when EQT's firm commitments commenced. The 20-year term firm transportation agreements for 550 MMcf per day of capacity on the EEP project commenced on July 1, 2024.

Forward Looking Statements. Any discussion included in this management discussion and analysis regarding the Company’s expectations, and any other expectations, such as relating to the MVP, refers to the expectations of the Company and its management at the time of filing this Quarterly Report on Form 10-Q with respect to the Company as a stand-alone company. Following the expected closing of the EQT Transaction on July 22, 2024, these expectations may no longer reflect the plans or expectations of the Company (or its successor) as a wholly owned subsidiary of EQT.

Business Segment Results

Operating segments are revenue-producing components of an enterprise for which separate financial information is produced internally and is subject to evaluation by the chief operating decision maker in deciding how to allocate resources. Headquarters costs consist primarily of transaction costs and other certain unallocated corporate expenses, as applicable. Net interest expense, loss on extinguishment of debt, components of other income (expense), net and income tax expense (benefit) are managed on a consolidated basis. The Company has presented each segment's operating income, other income (expense), net, equity income and various operational measures, as applicable, in the following sections. Management believes that the presentation of this information is useful to management and investors regarding the financial condition, results of operations and trends and uncertainties of its segments. The Company has reconciled each segment's operating income to the Company's consolidated operating income and net income in Note 3.

Three Months Ended June 30, 2024 Compared to Three Months Ended June 30, 2023

Gathering operating revenues increased by $19.8 million for the three months ended June 30, 2024 compared to the three months ended June 30, 2023. Volumetric-based fee revenues increased by $14.0 million primarily due to higher gathered volumes that previously were subject to MVC revenues. Firm reservation fee revenues increased by $5.8 million primarily due to new customer agreements and higher effective rates, partly offset by the aforementioned change in volumetric-based fee revenues caused by the expiration of MVCs under a certain customer contract.

Gathering operating expenses decreased by $9.9 million for the three months ended June 30, 2024 compared to the three months ended June 30, 2023. Selling, general and administrative expenses decreased by $11.7 million primarily due to personnel costs associated with the MVP PSU Program, including a cumulative catch-up, during the three months ended June 30, 2023, partially offset by an increased reserve for bad debt expense. Depreciation expense increased by $1.5 million as a result of additional assets placed in-service.

Six Months Ended June 30, 2024 Compared to Six Months Ended June 30, 2023

Gathering operating revenues increased by $33.7 million for the six months ended June 30, 2024 compared to the six months ended June 30, 2023. Volumetric-based fee revenues increased by $32.3 million primarily due to higher gathered volumes that previously were subject to MVC revenues and gathered volumes on Hammerhead of approximately $11.1 million. Firm reservation fee revenues increased by $1.4 million primarily due to new customer agreements and higher effective rates, partially offset by the aforementioned change in volumetric-based fee revenues caused by the expiration of MVCs under a certain customer contract.

Gathering operating expenses increased by $3.3 million for the six months ended June 30, 2024 compared to the six months ended June 30, 2023. Operating and maintenance expenses increased by $3.7 million primarily due to higher repairs and maintenance costs and higher personnel costs. Depreciation expense increased $2.3 million as a result of additional assets placed in-service. Selling, general and administrative expenses decreased by $2.7 million primarily due to personnel costs associated with the MVP PSU Program, including a cumulative catch-up, during the six months ended June 30, 2023, partially offset by higher legal fees, higher professional fees and an increased reserve for bad debt expense.

See "EQT Global GGA" in Part I, “Item 1. Business” in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 for discussion of the EQT Global GGA, and the transactions related thereto, including periodic gathering MVC fee step downs. Firm reservation fee revenues under the Company’s Hammerhead gathering agreement with EQT are expected to contribute to an increase in the Company’s firm reservation fee revenues following achievement of the Hammerhead pipeline full commercial in-service which was achieved in conjunction with full MVP in-service. However, the percentage of the Company's operating revenues that are generated by firm reservation fees may vary year to year depending on various factors, including customer volumes and the rates realizable under the Company’s contracts, including the EQT Global GGA. See also "Cautionary Statements," and "Commodity Price Risk" in Part I, "Item 3. Quantitative and Qualitative Disclosures About Market Risk" of this Quarterly Report on Form 10-Q for additional information on factors that could affect the Company's operating revenues, including the Company's perceived risk that producers could curtail production further in 2024.

Three Months Ended June 30, 2024 Compared to Three Months Ended June 30, 2023

Water operating revenues increased by $11.3 million for the three months ended June 30, 2024 compared to the three months ended June 30, 2023 primarily as a result of increased volumetric-based fee revenues from higher volumes and higher firm reservation fee revenues due to a new MVC contract.

Water operating expenses increased by $3.1 million for the three months ended June 30, 2024 compared to the three months ended June 30, 2023. Operating and maintenance expense increased $2.8 million due to higher purchased water costs as a result of increased activity and mixed-use water storage expenses related to a storage facility placed in-service during 2023.

Six Months Ended June 30, 2024 Compared to Six Months Ended June 30, 2023

Water operating revenues increased by $7.3 million for the six months ended June 30, 2024 compared to the six months ended June 30, 2023 as a result of increased volumetric-based fee revenues primarily from higher volumes and higher firm reservation fee revenues due to a new MVC contract.

Water operating expenses increased by $6.6 million for the six months ended June 30, 2024 compared to the six months ended June 30, 2023. Operating and maintenance expense increased $4.5 million due to higher mixed-use water storage expenses related to a storage facility placed in-service during 2023 and higher purchased water costs as a result of increased activity. Depreciation expense increased $1.8 million due to additional assets placed in-service.

The Company’s volumetric-based water services are directly associated with producers’ well completion activities and fresh and produced water needs (which are primarily driven by horizontal lateral lengths and the number of completion stages per well). Therefore, the Water volumetric operating results traditionally fluctuate from year-to-year in response to producers’ well completion activities.

Other Income Statement Items

Other Income (Expense), Net

Other income (expense), net decreased by $16.2 million for the three months ended June 30, 2024 compared to the three months ended June 30, 2023. The decrease was primarily attributable to a $3.2 million unrealized gain on derivative instruments during the three months ended June 30, 2024, as compared to a $19.4 million unrealized gain on derivative instruments during the three months ended June 30, 2023, primarily due to probability-weighted assumptions regarding MVP project completion (prior to in-service) associated with the Henry Hub cash bonus payment provision and changes in NYMEX Henry Hub natural gas futures prices.

Other income (expense), net decreased by $12.1 million for the six months ended June 30, 2024 compared to the six months ended June 30, 2023. The decrease was primarily due to a $1.5 million unrealized loss on derivative instruments during the six months ended June 30, 2024, as compared to a $10.9 million unrealized gain on derivative instruments during the six months ended June 30, 2023, primarily attributable to probability-weighted assumptions regarding MVP project completion (prior to in-service) associated with the Henry Hub cash bonus payment provision and changes in NYMEX Henry Hub natural gas futures prices.

See also Note 8 for a discussion of factors affecting the estimated fair value of the derivative asset attributable to the Henry Hub cash bonus payment provision that is recognized in other income (expense), net on the Company's statements of consolidated comprehensive income.

Net Interest Expense

Net interest expense increased by $16.5 million for the three months ended June 30, 2024 compared to the three months ended June 30, 2023 primarily due to increased borrowings and interest rates under the revolving credit facilities and interest on the 2024 Senior Notes issued in February 2024, partially offset by the redemption of the 2023 Notes effected in June 2023.

Net interest expense increased by $30.4 million for the six months ended June 30, 2024 compared to the six months ended June 30, 2023 primarily due to increased borrowings and interest rates under the revolving credit facilities and interest on the 2024 Senior Notes issued in February 2024, partially offset by the redemption of the 2023 Notes effected in June 2023.

See Note 7 for a discussion of certain of the Company's outstanding debt.

See Note 10 for an explanation of the changes in income tax expense for the three and six months ended June 30, 2024 compared to the three and six months ended June 30, 2023.

Net Income Attributable to Noncontrolling Interest

Net income attributable to noncontrolling interest decreased by $0.4 million and $1.9 million for the three and six months ended June 30, 2024, respectively, compared to the three and six months ended June 30, 2023, primarily as a result of lower net income on Eureka Midstream.

Capital Expenditures

See "Investing Activities" and "Capital Requirements" under "Capital Resources and Liquidity" for a discussion of capital expenditures and capital contributions.

Capital Resources and Liquidity

The Company's liquidity requirements are to finance its operations, its capital expenditures, strategic transactions and capital contributions to joint ventures, including the MVP Joint Venture, to pay distributions, when declared and to satisfy any indebtedness obligations. Additionally, the Company or its affiliates may, at any time and from time to time, seek to retire or purchase outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as the Company may determine, and will depend on prevailing market conditions, the Company's other liquidity requirements, contractual restrictions and other factors and the amounts involved may be material. The Company's ability to meet these liquidity requirements depends on the Company's cash flow from operations, the continued ability of the Company to borrow under its subsidiaries' credit facilities and the ability to raise capital in banking and capital markets. We believe that our cash on hand, future cash generated from operations and future cash received from potential distributions from the MVP Joint Venture, including as a result of potential financing at the MVP Joint Venture, together with available borrowing capacity under our subsidiaries' credit facilities and our access to banking and capital markets, will provide adequate resources to fund our short-term and long-term capital, operating and financing needs. However, cash flow, available borrowing capacity and capital raising activities may be affected by prevailing economic conditions in the natural gas industry and other financial and business factors, including factors discussed in Part I, “Item 1A. Risk Factors” in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 (for example, see “If we, our subsidiaries or our joint ventures are unable to obtain needed capital or financing on satisfactory terms, our ability to execute our business strategy and pay dividends to our shareholders may be diminished. Additionally, financing transactions may increase our financial leverage or could cause dilution to our shareholders.”) and factors discussed in Part II, “Item 1A. Risk Factors” in this Quarterly Report on Form 10-Q, some of which are beyond the Company's control. The Company's available sources of liquidity include cash from operations, cash on hand, borrowings under its subsidiaries' revolving credit facilities and issuances of additional debt. Taking into account the maximum Consolidated Leverage Ratio applicable under the Amended EQM Credit Facility that, as of June 30, 2024, could not exceed 6.25 to 1.00, EQM had the ability to borrow approximately $0.5 billion under the Amended EQM Credit Facility as of June 30, 2024. See Note 7 to the consolidated financial statements for further information regarding the Amended EQM Credit Facility. See also "Our subsidiaries’ significant indebtedness, and any future indebtedness, as well as the restrictions under our subsidiaries’ debt agreements, could adversely affect our operating flexibility, business, financial condition, results of operations, liquidity and ability to pay dividends to our shareholders." included in Part I, "Item 1A. Risk Factors" of the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

See “Security Ratings” below for a discussion of EQM’s credit ratings during 2024. Based on EQM's credit rating levels, EQM was obligated to deliver credit support to the MVP Joint Venture in the form of a letter of credit for the MVP project. On June 28, 2024, the $104.7 million letter of credit with respect to the MVP project was terminated, following MVP project in-service. See "A further downgrade of EQM’s credit ratings could impact our liquidity, access to capital, and costs of doing business." included in Part I, "Item 1A. Risk Factors" in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

Table of Contents

The following table is a summary of the cash flows by activity for the six months ended June 30, 2024 and 2023, respectively.

Net cash provided by (used in) financing activities	173,682		(244,505)
Net decrease in cash and cash equivalents	$	(116,998)	$	39,174

Operating Activities

Net cash flows provided by operating activities decreased approximately $86.7 million for the six months ended June 30, 2024 as compared to the six months ended June 30, 2023. The decrease was primarily due to higher interest and tax payments and the timing of other working capital payments and receipts.

Investing Activities

Net cash flows used in investing activities increased by approximately $487.6 million for the six months ended June 30, 2024 as compared to the six months ended June 30, 2023. The increase was primarily due to higher capital contributions to the MVP Joint Venture. See “Capital Requirements” below for a discussion of forecasted 2024 capital contributions to the MVP Joint Venture.

Financing Activities

Net cash flows provided by (used in) financing activities increased by $418.2 million for the six months ended June 30, 2024 as compared to the six months ended June 30, 2023. For the six months ended June 30, 2024, the primary sources of financing cash flows were proceeds from the issuance of the 2024 Senior Notes and borrowings under the revolving credit facilities, while the primary uses of financing cash flows were repayments on borrowings under the revolving credit facilities, payments of dividends to shareholders and distributions paid to noncontrolling interest. For the six months ended June 30, 2023, the primary uses of financing cash flows were the payments of dividends to shareholders, repayments on borrowings under the revolving credit facilities, the redemption of the 2023 Notes and distributions paid to noncontrolling interest, while the primary source of financing cash flows were borrowings under the revolving credit facilities.

Capital Requirements

The gathering, transmission and storage and water services businesses are capital intensive, requiring significant investment to develop new facilities and to maintain and upgrade existing operations.

During the six months ended June 30, 2024, the Company invested approximately $120.3 million in gathering projects (inclusive of capital expenditures related to the noncontrolling interest in Eureka Midstream) primarily for projects related to infrastructure expansion and optimization in core development areas in the Marcellus and Utica Shales in southwestern Pennsylvania, southeastern Ohio and northern West Virginia for EQT, Range Resources Corporation and other producers. During the six months ended June 30, 2024, the Company invested approximately $34.1 million in transmission projects primarily for the Company's Ohio Valley Connector expansion project and approximately $15.0 million in its water infrastructure primarily to continue to construct the initial mixed-use water system buildout.

Given the Company's targeted total MVP project cost of approximately $7.9 billion (excluding AFUDC) as discussed under “Executive Overview – Mountain Valley Pipeline and Related Long-Term Firm Capacity” above, the Company expects to make total capital contributions to the MVP Joint Venture in 2024 of approximately $750 million. Capital contributions payable to the MVP Joint Venture are accrued upon the issuance of a capital call by the MVP Joint Venture. The Company's short-term and long-term capital investments may vary significantly from period to period based on the available investment opportunities, the timing of projects, and maintenance needs. The Company expects to fund short-term and long-term capital expenditures and capital contributions primarily through cash on hand, future cash generated from operations and future cash received from potential distributions from the MVP Joint Venture, including as a result of potential financing at the MVP Joint Venture, together with available borrowing capacity under its subsidiaries' credit facilities and its access to banking and capital markets.

In light of the proposed EQT Transaction, on March 11, 2024, Moody's placed EQM's credit rating on Review for Upgrade and on March 12, 2024, S&P placed EQM’s credit rating on Credit Watch Developing, which, on June 12, 2024, was revised to Watch Positive given anticipated MVP in-service and the pending EQT Transaction. On February 21, 2024, Fitch removed the Rating Watch Positive and assigned a Stable Outlook for EQM as a result of the then-proposed 2024 Senior Notes offering and subsequently, on March 13, 2024, in light of the proposed EQT Transaction, Fitch placed EQM's credit rating on Rating Watch Positive. EQM's credit ratings are subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be evaluated independently of any other rating. The Company cannot ensure that a rating will remain in effect for any given period of time or that a rating will not be lowered or withdrawn entirely by a credit rating agency if, in its judgment, circumstances so warrant. If any credit rating agency downgrades or withdraws EQM's ratings, the Company's access to the capital markets could become more challenging, borrowing costs will likely increase, the Company may, depending on contractual provisions in effect at such time, be required to provide additional credit assurances (the amount of which may be substantial) and the potential pool of investors and funding sources may decrease. In order to be considered investment grade, a company must be rated Baa3 or higher by Moody's, BBB- or higher by S&P, or BBB- or higher by Fitch. All of EQM's credit ratings are considered non-investment grade.

Commitments and Contingencies

From time to time, various legal and regulatory claims and proceedings are pending or threatened against the Company and its subsidiaries. While the amounts claimed may be substantial, the Company is unable to predict with certainty the ultimate outcome of such claims and proceedings. The Company accrues legal and other direct costs related to loss contingencies when incurred. The Company establishes reserves whenever it believes it to be appropriate for pending matters. Furthermore, after consultation with counsel and considering the availability, if any, of insurance, the Company believes, although no assurance can be given, that the ultimate outcome of any matter currently pending against it or any of its consolidated subsidiaries as of the filing of this Quarterly Report on Form 10-Q will not materially adversely affect its business, financial condition, results of operations, liquidity or ability to pay dividends to its shareholders.

See Note 14 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 for further discussion of the Company's commitments and contingencies.

Critical Accounting Estimates

The Company's critical accounting policies are described in Part II, "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Any new accounting policies or updates to existing accounting policies as a result of new accounting pronouncements have been included in the notes to the Company's consolidated financial statements in Part I, "Item 1. Financial Statements" of this Quarterly Report on Form 10-Q. Preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts in the Company's consolidated financial statements and accompanying notes. The Company's critical accounting policies are considered critical due to the significant judgments and estimates used in the preparation of the Company's consolidated financial statements and the material impact on the results of operations or financial condition. Actual results could differ from those judgments and estimates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Except for Commodity Price Risk described below, information about market risks for the six months ended June 30, 2024, does not differ materially from that discussed under Part II, "Item 7A." of the Company's Annual Report on Form 10-K for the year ended December 31, 2023, as updated for the six months ended June 30, 2024.

Table of Contents

Commodity Price Risk. The Company's business is dependent on continued natural gas production and the availability and development of reserves in its areas of operation. Prices for natural gas and NGLs, including regional basis differentials, have previously adversely affected, and may in the future adversely affect, timing of development of additional reserves and production that is accessible by the Company’s pipeline and storage assets, which also negatively affects the Company’s water services business, and the creditworthiness of the Company’s customers.

Lower natural gas prices, particularly in the Appalachian region, have caused, and may in the future cause, producers such as EQT to determine to take actions to slow production growth and/or maintain flat or reduce production, which when effected by our producer customers limits growth in and reduces the demand for, and usage of, our services. For instance, on March 4, 2024, EQT in response to the low natural gas price environment announced its curtailment of approximately one Bcf per day of its gross production, a significant portion of which curtailment was realized on the Company's systems beginning in late February 2024. On April 23, 2024, EQT announced it assumed curtailments of approximately one Bcf per day of its operated production to continue through May 2024 and acknowledged the potential for future curtailments depending on market conditions. Based on the forward price strip as of July 18, 2024 and the curtailments realized on the Company's systems in the first half of 2024, the Company perceives risk that EQT and/or other producers could curtail production further in 2024 or maintain at flat levels, which, depending on the nature and duration of any such curtailment and systems affected thereby, could have a significant negative effect on the demand for our services, our volumetric-based fee revenue, and therefore our results of operations, and any such maintenance may limit growth associated with our assets. See also “Decreases or a lack of growth in production of natural gas in our areas of operation, whether as a result of regional takeaway constraints, producer corporate capital allocation strategies, lower regional natural gas prices, natural well decline, and/or other factors, have adversely affected, and in the future could adversely affect, our business and operating results and reduce our cash available to pay cash dividends to our shareholders.”, "The lack of diversification of our assets and geographic locations could adversely affect us." and “We generate a substantial majority of our revenues from EQT. Therefore, we are subject to the business and liquidity risks of EQT, and any decrease in EQT's drilling or completion activity (or significant production curtailments) or a shift in such activity away from our assets could adversely affect our business and operating results.”, each included in Part I, "Item 1A. Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

Price declines and sustained periods of low natural gas and NGL prices could have an adverse effect on the creditworthiness of the Company's customers and related ability to pay firm reservation fees under long-term contracts and/or affect, as discussed above, activity levels and, accordingly, volumetric-based fees, which could affect the Company’s results of operations, liquidity or financial position. Credit risk and related management is further discussed under “Credit Risk” in Part II, “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

Increases in natural gas prices do not necessarily result in corresponding increases to the production forecasts of the Company's customers. Even when natural gas prices have been commercially attractive, certain of the Company's customers maintained largely flat production forecasts in light of, among other things, the absence of incremental takeaway capacity from the Appalachian Basin and the Company's customers may still maintain flat or modest increases to production forecasts based on various factors, which could include regional takeaway capacity limitations, access to capital, investor expectations regarding free cash flow, a desire to reduce or refinance leverage or other factors.

Additionally, lower natural gas prices (including regionally), corporate capital allocation strategies or regional takeaway constraints, could cause producers to determine in the future that drilling activities in areas outside of the Company's current areas of operation are strategically more attractive to them.

Many of the Company’s customers, including EQT, have entered into long-term firm reservation gathering, transmission and water services contracts or contracts with MVCs or ARCs, as applicable, on the Company's systems and approximately 68% of the Company's operating revenues for the six months ended June 30, 2024 was generated by firm reservation fee revenues. The Company believes that such contract structure is advantageous to its overall business, although significant declines in gas production, including through curtailments, in the Company's areas of operations would likely adversely affect the Company's results of operations, financial condition and liquidity as approximately 32% of the Company’s operating revenues for the six months ended June 30, 2024 was generated by volumetric-based fee revenues. See “Our exposure to commodity price risk may increase in the future and NYMEX Henry Hub futures prices affect the fair value, and may affect the realizability, of potential cash payments to us by EQT pursuant to the EQT Global GGA.” and “We generate a substantial majority of our revenues from EQT. Therefore, we are subject to the business and liquidity risks of EQT, and any decrease in EQT’s drilling or completion activity (or significant production curtailments) or a shift in such activity away from our assets could adversely affect our business and operating results.” included in Part I, “Item 1A. Risk Factors” in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

While EQT has dedicated a substantial portion of its core acreage in southwestern Pennsylvania and West Virginia to the Company and has entered into long-term firm gathering and transmission contracts and contracts with MVCs on certain of the Company's systems, EQT may determine in the future that drilling or continuing to produce gas from existing wells in the Company's areas of operations is not economical above the amount to fulfill its required MVCs or otherwise further strategically determine to curtail volumes on the Company's systems. Other than with respect to its MVCs and other firm commitments under existing contracts, EQT is under no contractual obligation to continue to develop its acreage dedicated to the Company. See also "EQT Global GGA" in Part I, “Item 1. Business” in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 and Part I, "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" for discussion of the EQT Global GGA.

The fair value of the Company’s derivative instruments is, in part, determined by estimates of the NYMEX Henry Hub natural gas forward price curve. A hypothetical 10% increase in NYMEX Henry Hub natural gas futures prices would increase the valuation of the Company’s derivative instruments by approximately $7.9 million, while a hypothetical 10% decrease in NYMEX Henry Hub natural gas futures prices would decrease the valuation of the Company’s derivative instruments by approximately $7.5 million. This fair value change assumes volatility based on prevailing market parameters at June 30, 2024. See Note 8 of this Quarterly Report on Form 10-Q for a discussion of the Henry Hub cash bonus payment provision.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Under the supervision and with the participation of management, including the Company's Principal Executive Officer and Principal Financial Officer, an evaluation of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)), was conducted as of the end of the period covered by this report. Based on that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that the Company's disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Control over Financial Reporting. There were no changes in internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that occurred during the second quarter of 2024 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, various legal and regulatory claims, investigations and proceedings are pending or threatened against the Company and its subsidiaries. While to the extent applicable the amounts claimed may be substantial, the Company is unable to predict with certainty the ultimate outcome of such claims, investigations and proceedings. The Company accrues legal and other direct costs related to loss contingencies when incurred. The Company establishes reserves whenever it believes a reserve is appropriate for pending matters. Furthermore, after consultation with counsel and considering the availability, if any, of insurance, the Company believes, although no assurance can be given, that the ultimate outcome of any matter currently pending against it or any of its consolidated subsidiaries as of the filing of this Quarterly Report on Form 10-Q will not materially adversely affect its business, financial condition, results of operations, liquidity or ability to pay dividends to its shareholders.

Environmental Proceedings

Pratt Storage Field. On October 31, 2018, a gas explosion occurred in Morgan Township, Greene County, Pennsylvania (the Incident). Following the explosion, the Pennsylvania Department of Environmental Protection (the PADEP), the Pennsylvania Public Utilities Commission and the PHMSA began investigating the Incident. In October 2019, the PADEP notified the Company that it was required to submit an investigation report pursuant to the state’s gas migration regulations due to the Incident's proximity to the Company's Pratt Storage Field assets. The Company, while disputing the applicability of the regulations, submitted a report to the PADEP in May 2020. In September 2020, the PADEP responded to the Company’s investigation report with a request for additional information. The Company responded to the September 2020 request. Over the next months the Company provided many responses to the PADEP’s continuing information requests. The PADEP issued a final report and closed its investigation and the Company does not expect further inquiry from the PADEP on this matter. On October 23, 2023, the Company received permission from the FERC to plug and abandon the well in the Pratt Storage Field that was the subject of the PADEP’s investigation of the Company. Additionally, the Company is continuing to defend in a civil litigation related to the Incident.

On October 30, 2023, the Company received a criminal complaint from the State Attorney General’s Office charging the Company with violations of the Clean Streams Law (the Pratt Complaint). In response to the Pratt Complaint, the Company intends to fully assert its rights and defenses to the claims raised. The Pratt Complaint carries the possibility of a monetary sanction, that if imposed could result in a fine in excess of $300,000. The Pratt Complaint could also cause reputational or other adverse impacts.

Rager Mountain Storage Field. On November 6, 2022, the Company became aware of natural gas venting from one of the storage wells, well 2244, at Equitrans, L.P.’s Rager Mountain natural gas storage facility (Rager Mountain facility), located in Jackson Township, a remote section of Cambria County, Pennsylvania, which venting was halted on November 19, 2022. Since the time of the incident, the PADEP has concluded its investigation and PHMSA and other investigators are continuing to conduct civil and criminal investigations of the incident and the Company is cooperating in such investigations. On December 7, 2022, the Company and its subsidiary Equitrans, L.P. each separately received an order from the PADEP alleging, in connection with earth disturbance activities undertaken to halt the venting of natural gas from well 2244, (i) in the case of the order received by the Company, violations of Pennsylvania’s Clean Streams Law and requiring certain remedial actions and (ii) in the case of the order received by Equitrans, L.P., violations of Pennsylvania’s 2012 Oil and Gas Act, Clean Streams Law and Solid Waste Management Act and requiring certain remedial actions. On December 8, 2022, the PADEP submitted a compliance order to Equitrans, L.P. relating to certain alleged violations of law in respect of wells at the Rager Mountain natural gas storage field and the venting of natural gas, including from well 2244. The December 8, 2022 order also prohibited Equitrans, L.P. from injecting natural gas into the storage wells at the Rager Mountain facility. The Company and Equitrans, L.P. disputed aspects of the applicable orders, and on January 5, 2023, the Company and Equitrans, L.P., as applicable, appealed each of the orders to the Commonwealth of Pennsylvania Environmental Hearing Board. Additionally, the Company and Equitrans, L.P., as applicable, received notices of violation (NOVs) related to the incident that alleged violations of various Pennsylvania statutes and regulations. The Company engaged in discussions with the PADEP to address the outstanding NOVs. Equitrans, L.P. and the PADEP entered into a Stipulation of Settlement on April 12, 2023 that, among other things, resulted in the PADEP rescinding its December 8, 2022 order and Equitrans, L.P. withdrawing its appeal of such order.

On April 4, 2024, Equitrans, L.P. and the PADEP entered into a Stipulation of Settlement, that, among other things, resulted in the PADEP deeming the December 7, 2022 orders to the Company and Equitrans, L.P. Administratively Closed. On April 4, 2024, the PADEP issued a Civil Penalty Assessment (CPA) in the amount of $764,000, of which $549,500 is reimbursement of PADEP’s expenses. This CPA closed the outstanding NOVs issued by the PADEP’s Office of Oil and Gas Management. On October 5, 2023, Equitrans, L.P. received a NOV from the PADEP’s Bureau of Air Quality Management for the release of

uncontrolled hydrocarbons to the atmosphere during the Rager Mountain natural gas storage field incident. On April 8, 2024, the PADEP’s Bureau of Air Quality Management executed a Consent Assessment of Civil Penalty (CACP) that settled the associated NOV and included an agreed upon civil penalty of $350,000. Payment of this civil penalty settled the applicable matters within the October 5, 2023 NOV. The Company paid the civil penalties on April 8, 2024 and April 15, 2024, respectively.

On December 29, 2022, the PHMSA issued the Company a Notice of Proposed Safety Order that included proposed remedial requirements related to the Rager Mountain natural gas storage field incident, including, but not limited to, completing a root cause analysis. The Company addressed certain proposals in advance of an order from the agency. These efforts included conducting testing, evaluating other wells at the Rager field and hiring a third-party specialist firm to undertake a root cause analysis, and subsequently on May 26, 2023, the PHMSA issued a consent order to the Company incorporating the terms of a consent agreement between the parties, which, among other things, required the completion of a root cause analysis and a remedial work plan, and specified that the Company may not resume injection operations at the Rager Mountain facility until authorized by the PHMSA. In August 2023, the Company submitted a root cause analysis to the PHMSA in accordance with the consent order and later submitted a remedial work plan and, following completion of all actions in its remedial work plan, an injection plan to the PHMSA seeking authority to resume injections at Rager Mountain using all wells except three, which remain disconnected. On October 2, 2023, the PHMSA approved the Company’s injection plan. The Company began injections at Rager Mountain on October 5, 2023, subject to certain pressure restrictions and other requirements specified in the consent agreement between the PHMSA and the Company. On November 16, 2023, the PHMSA issued a letter to the Company approving the Company’s request to remove all pressure restrictions at the Rager Mountain facility. On May 30, 2024, the PHMSA approved resuming operations for one of the three remaining wells, which remains disconnected. The Company plans to continue working with the PHMSA, pursuant to the consent order, regarding the remaining two wells.

If additional penalties are pursued and ultimately imposed related to the Rager Mountain natural gas storage field incident, the penalties, individually and/or in the aggregate, are not expected to have a material adverse impact on the Company's financial condition, results of operations or liquidity, however, there can be no assurance as of the filing of this Quarterly Report on Form 10-Q regarding the scope of potential (or ultimately actual) financial or other impacts to the Company as a result of the Rager Mountain natural gas storage field incident.

MVP Matters

•Challenges to FERC Certificate, D.C. Circuit. Multiple parties have sought judicial review of the FERC’s order issuing a certificate of public convenience and necessity to the MVP Joint Venture and/or the exercise by the MVP Joint Venture of eminent domain authority. On February 19, 2019, the D.C. Circuit issued an order rejecting multiple consolidated petitions seeking direct review of the FERC order under the Natural Gas Act of 1938, as amended (NGA) and certain challenges to the exercise by the MVP Joint Venture of eminent domain authority in Appalachian Voices, et al. v. FERC, et al., consolidated under Case No. 17-1271. No petitions for rehearing or petitions for rehearing en banc were filed by the April 5, 2019 deadline. The mandate was issued on April 17, 2019. Another group of parties filed a complaint in the U.S. District Court for the District of Columbia asserting that the FERC’s order issuing certificates is unlawful on constitutional and other grounds in Bold Alliance, et al. v. FERC, et al., Case No. 17-1822. The district court plaintiffs sought declaratory relief as well as an injunction preventing the MVP Joint Venture from developing its project or exercising eminent domain authority. In December 2017 and January 2018, the FERC and the MVP Joint Venture, respectively, moved to dismiss the petitions for lack of subject matter jurisdiction. The court granted the motion and dismissed plaintiffs’ complaint on September 28, 2018. On October 26, 2018, plaintiffs appealed the decision in Case No. 17-1822 to the D.C. Circuit in Bold Alliance, et al. v. FERC, et al., Case No. 18-5322. On December 3, 2018, the FERC, as appellee, filed a joint motion with the appellants to hold Case No. 18-5322 in abeyance pending completion of the appeals of the final agency orders related to the MVP certificate in consolidated Case No. 17-1271 and Atlantic Coast Pipeline’s (ACP) certificate. The MVP Joint Venture filed a motion to dismiss the case as to some of the plaintiffs. On February 15, 2019, the D.C. Circuit entered an order holding this appeal in abeyance pending rulings on the appeals from the ACP and MVP FERC proceedings. The ACP petitioners on November 16, 2022, filed a joint motion for voluntary dismissal of all petitions for review pertaining to ACP, except for the Bold Alliance proceeding. The court granted the motion on November 17, 2022. On January 5, 2023, the D.C. Circuit entered an order holding the Bold Alliance proceeding in abeyance pending further order of the court and requiring the parties to file motions to govern future proceedings within 60 days of the U.S. Supreme Court disposition of the petition for writ of certiorari in Bohon et al. v. FERC et al., discussed below. On April 19, 2024, the appellants filed a motion to voluntarily dismiss their appeal. On May 1, 2024, the D.C. Circuit granted that motion and issued its mandate.

Similarly, another group of parties filed a complaint in the U.S. District Court for the District of Columbia in Bohon et al. v. FERC et al., Case No. 20-00006, asserting that the delegation of authority to the FERC under the NGA violates

Table of Contents

the nondelegation doctrine and separation-of-powers principle of the U.S. Constitution. The MVP Joint Venture and the FERC filed motions to dismiss which were granted by the court. On July 6, 2020, the landowners filed a notice of appeal to the D.C. Circuit in Case No. 20-5203. On November 30, 2020, appellants asked the D.C. Circuit to overturn the decision of the lower court. The D.C. Circuit issued an order on September 15, 2021 denying appellants’ motion for summary reversal of the decision of the lower court and supplemental briefing was completed as of October 6, 2021. On June 21, 2022, the D.C. Circuit upheld the lower court’s decision to dismiss the lawsuit. On September 15, 2022, the petitioners filed a petition for writ of certiorari with the U.S. Supreme Court. The FERC and the MVP Joint Venture filed responses to the petition in November 2022. On April 24, 2023, the U.S. Supreme Court granted the petition for certiorari, vacated the judgment, and remanded the case to the D.C. Circuit for further consideration in light of the U.S. Supreme Court’s April 14, 2023 opinion in Axon Enterprises, Inc. v. FTC. The D.C. Circuit subsequently issued an order authorizing, among other things, the parties to address in their supplemental briefing the implications of Section 324 of the Fiscal Responsibility Act of 2023 in addition to Axon. On October 24, 2023, the D.C. Circuit denied a stay motion filed by the petitioners. The parties filed their respective supplemental briefs on November 13, 2023. On November 26, 2023, the petitioners filed in the U.S. Supreme Court an “emergency” motion for an injunction requesting a judicial injunction on, or access to, the petitioners’ three properties pending resolution of their underlying claims in the Bohon matter. On December 5, 2023, Chief Justice John Roberts denied the application, without calling for a response from the MVP Joint Venture or the federal government. On February 13, 2024, the D.C. Circuit affirmed and reinstated its June 21, 2022 judgment upholding the lower court's decision to dismiss the lawsuit. On March 22, 2024, the petitioners filed a petition for writ of certiorari with the U.S. Supreme Court requesting a review of the D.C. Circuit’s decision. On May 20, 2024, the U.S. Supreme Court denied the petition.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Financial Statements	Financial Statements Nature of Business. The Company's operating subsidiaries provide midstream services to the Company's customers in Pennsylvania, West Virginia and Ohio through three primary assets: the gathering system, which includes predominantly dry gas gathering systems of high-pressure gathering lines; the transmission system, which includes FERC-regulated interstate pipelines and storage systems; and the water network, which primarily consists of water pipelines and other facilities that support well completion activities and produced water handling activities. Basis of Presentation. References in these financial statements to Equitrans Midstream or the Company refer collectively to Equitrans Midstream Corporation and its consolidated subsidiaries for all periods presented, unless otherwise indicated. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial information and with the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these unaudited consolidated financial statements include all adjustments (consisting of only normal, recurring adjustments, unless otherwise disclosed in this Quarterly Report on Form 10-Q) necessary for a fair presentation of the financial position of the Company as of June 30, 2024, the results of its operations, and equity for the three and six months ended June 30, 2024 and 2023 and its cash flows for the six months ended June 30, 2024 and 2023. The consolidated balance sheet at December 31, 2023 has been derived from the audited financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2023, which includes all disclosures required by GAAP. Due to, among other things, the seasonal nature of the Company's utility customer contracts, as well as producers’ well completion activities and varying needs for fresh and produced water (which are primarily driven by horizontal lateral lengths and the number of completion stages per well), the interim statements for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. For further information, refer to the Company's consolidated financial statements and related notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, as well as Part I, "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" contained herein. Recently Issued Accounting Standards. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides improvements to reportable segment disclosures and is intended to enhance the disclosures regarding significant segment expenses. The guidance is applicable to all public entities that are required to report segment information in accordance with Topic 280 and is to be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the potential impact of adopting this standard on its financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures, which provides improvements to income tax disclosures and is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The guidance is applicable to all public entities required to report income taxes in accordance with ASC 740 and should be applied prospectively, but retrospective application is permitted. The standard requires disaggregated information about a reporting entity’s effective tax rate reconciliation, information on income taxes paid, and various other disclosure changes. The Company is currently evaluating the potential impact of adopting this standard on its financial statements and related disclosures.

On March 10, 2024, the Company, EQT Corporation (Parent), Humpty Merger Sub Inc., an indirect wholly owned subsidiary of Parent (Merger Sub), and Humpty Merger Sub LLC, an indirect wholly owned subsidiary of Parent (LLC Sub), entered into an Agreement and Plan of Merger (the Merger Agreement), pursuant to which, among other things, Merger Sub will merge with and into the Company (the First Merger), with the Company surviving the First Merger as an indirect wholly owned subsidiary of Parent (the First Step Surviving Corporation) and, as the second step in a single integrated transaction, the First Step Surviving Corporation will merge with and into LLC Sub (the Second Merger and, together with the First Merger, the Mergers), with LLC Sub surviving the Second Merger as an indirect wholly owned subsidiary of Parent (the transactions contemplated by the Merger Agreement, the EQT Transaction). Under the terms of the Merger Agreement, and subject to the satisfaction or waiver of certain conditions therein, at the effective time of the First Merger (the Effective Time), (i) each share of common stock, no par value per share, of Equitrans Midstream Corporation (Equitrans Midstream common stock) issued and outstanding immediately prior to the Effective Time (excluding any excluded shares) will be converted automatically at the Effective Time into the right to receive 0.3504 (the Exchange Ratio) fully-paid and nonassessable shares of common stock of Parent, no par value per share (EQT Shares) and (ii) each Equitrans Midstream Corporation Series A Perpetual Convertible Preferred Share, no par value (Equitrans Midstream Preferred Share), issued and outstanding immediately prior to the Effective Time will be treated in accordance with Section 8 of the Company’s Second Amended and Restated Articles of Incorporation and the procedures set forth in Section 2.5 of the Merger Agreement. The EQT Transaction is expected to close on July 22, 2024, taking into account, as of the filing of this Quarterly Report on Form 10-Q, the satisfaction in accordance with the terms and conditions of the Merger Agreement of various conditions to closing under the Merger Agreement, including, among others: (i) approval of the Merger Agreement and the Mergers by a majority of the votes cast by holders of Equitrans Midstream common stock and Equitrans Midstream Preferred Shares, with such Equitrans Midstream Preferred Shares treated as Equitrans Midstream common stock on an as-converted basis, voting together as a single class, (ii) approval of the issuance of EQT Shares in connection with the Mergers by a majority of votes cast at a special meeting of holders of EQT Shares, (iii) expiration or termination of (a) all waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the HSR Act) and (b) any commitment to, or agreement with, any governmental entity to delay the consummation of, or not to consummate the transactions contemplated by the Merger Agreement, and (iv) the MVP Joint Venture receiving authorization of the Federal Energy Regulatory Commission (FERC) to place the Mountain Valley Pipeline (MVP) in-service. The Company recorded approximately $2.0 million and $7.7 million in expenses related to the EQT Transaction during the three and six months ended June 30, 2024, respectively, primarily related to advisor, legal and other transaction-related fees, which are included in transaction costs on the Company's statements of consolidated comprehensive income. Equitrans Midstream Preferred Shares Redemption. On June 25, 2024, Parent delivered to the Company a written election exercising Parent’s right under the Merger Agreement to cause the Company to purchase and redeem, prior to the Effective Time, all issued and outstanding Equitrans Midstream Preferred Shares in accordance the Company’s Second Amended and Restated Articles of Incorporation. The Company has no obligation to purchase and redeem the Equitrans Midstream Preferred Shares in accordance with the Merger Agreement unless Parent has deposited with the paying agent for such redemption sufficient funds to effect such purchase and redemption, and the deposit of such funds and any instructions and authority to pay such funds to holders of the Equitrans Midstream Preferred Shares in the redemption has occurred at least one hour prior to the consummation of the proposed EQT Transaction. In the event the EQT Transaction will not be consummated, the redemption will not be effected. Subject to the foregoing, the Company expects the purchase and redemption to occur on July 22, 2024 prior to the consummation of the EQT Transaction (or such later date as may be contemplated by virtue of the timing of the consummation of the EQT Transaction). The Equitrans Midstream Preferred Shares are presented as temporary equity in the mezzanine equity section of the Company’s consolidated balance sheets. As the Equitrans Midstream Preferred Shares were not redeemable or probable of becoming redeemable as of June 30, 2024, adjustment to the carrying amount is not necessary and would only be required if the Equitrans Midstream Preferred Shares are redeemed in accordance with the events described above.

Share-based Compensation Plans	Jun. 30, 2024
Share-Based Payment Arrangement [Abstract]
Share-based Compensation Plans	Share-based Compensation Plans In December 2021, the Company granted a special, one-time, performance award program designed to reward all employees should the Company’s most complex and strategically significant project, the MVP project, be placed in-service, subject to continued service through the applicable payment date (the MVP PSU Program). The achievement of the MVP Joint Venture being authorized by the FERC to commence service on the MVP represented a performance condition as defined by ASC 718, Share-based Compensation. During the second quarter of 2024, the MVP Joint Venture was authorized by the FERC to commence service on the MVP. As such, the performance condition of the MVP PSU Program was achieved and the award vested and was paid in Company common stock on June 28, 2024. Certain shares of the MVP PSU Program remain outstanding and are subject to continued service through the first and second anniversaries of the in-service date. In June 2023, the performance condition associated with the MVP PSU Program awards was deemed to be probable, and the Company recognized compensation cost of approximately $16.8 million that included the cumulative catch-up of approximately $14.1 million to reflect the requisite service period of each award that had been provided to date. As of June 30, 2024, there was approximately $1.7 million of unrecognized compensation cost related to non-vested MVP PSU Program awards that is expected to be recognized over a remaining weighted average vesting term of approximately 1.4 years.

Debt	6 Months Ended
Debt	Jun. 30, 2024
Debt Disclosure [Abstract]
Debt	Debt Amended EQM Credit Facility. On February 15, 2024 (the Fifth Amendment Date), EQM entered into an amendment (the Fifth Amendment) to the Third Amended and Restated Credit Agreement, dated as of October 31, 2018 (as amended, supplemented or otherwise modified, the Amended EQM Credit Facility), among EQM, as borrower, Wells Fargo Bank, National Association, as the administrative agent, swing line lender and an L/C issuer, the lenders party thereto from time to time and any other persons party thereto from time to time. The Fifth Amendment, among other things, amended the financial covenant, such that the Consolidated Leverage Ratio (as defined in the Amended EQM Credit Facility) (i) as of March 31, 2024, could not exceed 6.00 to 1.00, (ii) as of June 30, 2024, could not exceed 6.25 to 1.00, (iii) as of September 30, 2024, cannot exceed 5.85 to 1.00 and (iv) as of the end of each fiscal quarter thereafter, cannot exceed 5.50 to 1.00. EQM has or, as applicable, will have aggregate commitments available under the Amended EQM Credit Facility of approximately $1.55 billion prior to April 30, 2025, and approximately $1.45 billion on and after April 30, 2025 and prior to April 30, 2026. For the avoidance of doubt, any reference to the Amended EQM Credit Facility as of any particular date shall mean the Amended EQM Credit Facility as in effect on such date. As of June 30, 2024, EQM had $655 million of borrowings and approximately $1.0 million of letters of credit outstanding under the Amended EQM Credit Facility. As of December 31, 2023, EQM had $915 million of borrowings and approximately $105.8 million of letters of credit outstanding under the Amended EQM Credit Facility. Taking into account the maximum Consolidated Leverage Ratio applicable under the Amended EQM Credit Facility that, as of June 30, 2024, could not exceed 6.25 to 1.00, EQM had the ability to borrow approximately $0.5 billion under the Amended EQM Credit Facility as of June 30, 2024. The Company believes that its cash on hand, future cash generated from operations and future cash received from potential distributions from the MVP Joint Venture, including as a result of potential financing at the MVP Joint Venture, together with available borrowing capacity under its subsidiaries' credit facilities and its access to banking and capital markets, will provide adequate resources to fund its short-term and long-term capital, operating and financing needs. During the three and six months ended June 30, 2024, the maximum outstanding borrowings at any time were approximately $655 million and $1,055 million, respectively, the average daily balances were approximately $545 million and $690 million, respectively, and the weighted average annual interest rate was approximately 8.3%. For the three and six months ended June 30, 2024, commitment fees of $1.2 million and $1.9 million, respectively, were paid to maintain credit availability under the Amended EQM Credit Facility. During the three and six months ended June 30, 2023, the maximum outstanding borrowings at any time were approximately $255 million and $315 million, respectively, the average daily balances were approximately $191 million and $225 million, respectively, and the weighted average annual interest rates were approximately 7.9% and 7.7%, respectively. For the three and six months ended June 30, 2023, commitment fees of $2.3 million and $4.4 million, respectively, were paid to maintain credit availability under the Amended EQM Credit Facility. As of June 30, 2024 and December 31, 2023, no term loans were outstanding under the Amended EQM Credit Facility. The Amended EQM Facility contains negative covenants that, among other things, limit restricted payments, the incurrence of debt, dispositions, mergers and other fundamental changes, and transactions with affiliates, in each case and as applicable, subject to certain specified exceptions. In addition, the Amended EQM Credit Facility contains certain specified events of default such as insolvency, nonpayment of scheduled principal or interest obligations, change of control and cross-default related to the acceleration or default of certain other financial obligations. Eureka Credit Facility. Eureka has a $400 million senior secured revolving credit facility with Sumitomo Mitsui Banking Corporation, as administrative agent, the lenders party thereto from time to time and any other persons party thereto from time to time (the 2021 Eureka Credit Facility) that matures in November 2025. As of June 30, 2024, and December 31, 2023, Eureka had $330 million and $315 million, respectively, of borrowings outstanding under the 2021 Eureka Credit Facility. For the three and six months ended June 30, 2024, the maximum amount of outstanding borrowings under the 2021 Eureka Credit Facility at any time were approximately $330 million, the average daily balances were approximately $330 million and $326 million, respectively, and Eureka incurred interest at a weighted average annual interest rate of approximately 8.3%. For the three and six months ended June 30, 2024, commitment fees of $0.1 million and $0.2 million, respectively, were paid to maintain credit availability under the 2021 Eureka Credit Facility.

For the three and six months ended June 30, 2023, commitment fees of $0.1 million and $0.2 million, respectively, were paid to maintain credit availability under the 2021 Eureka Credit Facility. The 2021 Eureka Credit Facility contains negative covenants that, among other things, limit restricted payments, the incurrence of debt, dispositions, mergers and other fundamental changes, and transactions with affiliates, in each case and as applicable, subject to certain specified exceptions. In addition, the 2021 Eureka Credit Facility contains certain specified events of default such as insolvency, nonpayment of scheduled principal or interest obligations, loss and failure to replace certain material contracts, change of control and cross-default related to the acceleration or default of certain other financial obligations. 2024 Senior Notes. On February 26, 2024, EQM completed a private offering of $600 million in aggregate principal amount of new 6.375% senior notes due 2029 (the 2024 Senior Notes) and received net proceeds from the offering of approximately $590.6 million inclusive of a discount of approximately $7.5 million and debt issuance costs of approximately $1.9 million. EQM used the net proceeds from the 2024 Senior Notes offering to repay certain outstanding indebtedness, including borrowings under the Amended EQM Credit Facility, and for general partnership purposes. The 2024 Senior Notes were issued under and are governed by an indenture, dated February 26, 2024 (the 2024 Indenture), between EQM and U.S. Bank Trust Company, National Association, as trustee (the Trustee). The 2024 Indenture contains covenants that limit EQM’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of EQM’s assets. The 2024 Senior Notes will mature on April 1, 2029 and interest on the 2024 Senior Notes is payable semi-annually in arrears on April 1 and October 1 of each year, commencing on October 1, 2024. The 2024 Senior Notes are unsecured and rank equally in right of payment with all of EQM’s existing and future senior indebtedness. The 2024 Senior Notes are senior in right of payment to any of EQM’s future indebtedness that are, by their terms, expressly subordinated in right of payment to the 2024 Senior Notes. The 2024 Senior Notes are effectively subordinated to EQM’s future secured indebtedness, if any, to the extent of the value of the assets securing such indebtedness, and structurally subordinated to all existing and future obligations, including trade payables, of EQM’s subsidiaries, other than any subsidiaries that may guarantee the Notes in the future. EQM may, at its option, redeem some or all of the 2024 Senior Notes, in whole or in part, at any time prior to their maturity at the applicable redemption price as set forth in the Indenture. Upon the occurrence of a Change of Control Triggering Event (as defined in the 2024 Indenture), EQM may be required to offer to purchase the 2024 Senior Notes at a purchase price equal to 101% of the aggregate principal amount of the 2024 Senior Notes repurchased, plus accrued and unpaid interest, if any, on the 2024 Senior Notes repurchased, to, but excluding, the date of settlement, subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of settlement. The 2024 Indenture contains certain events of default (each an Event of Default), including the following: (1) default in the payment of interest on such 2024 Senior Notes when due that continues for 30 days; (2) default in the payment of principal of or premium, if any, on any such 2024 Senior Notes when due, whether at its stated maturity, upon redemption or otherwise; (3) failure by EQM or any subsidiary guarantor, if any, to comply for 90 days with the other agreements with respect to such 2024 Senior Notes contained in the 2024 Indenture after written notice by the Trustee or by the holders of at least 25% in principal amount of the outstanding 2024 Senior Notes; (4) certain events of bankruptcy, insolvency or reorganization of EQM or any subsidiary guarantor, if any, that is one of EQM’s Significant Subsidiaries (as defined in the 2024 Indenture); and (5) if such 2024 Senior Notes are guaranteed by a subsidiary guarantor that is one of EQM’s Significant Subsidiaries, (a) the guarantee of that subsidiary guarantor ceases to be in full force and effect, except as otherwise provided in the 2024 Indenture; (b) the guarantee of that subsidiary guarantor is declared null and void in a judicial proceeding; or (c) such subsidiary guarantor denies or disaffirms its obligations under the 2024 Indenture or its guarantee. If an Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding 2024 Senior Notes may declare the principal of and all accrued and unpaid interest on such 2024 Senior Notes to be immediately due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization occurs, the principal of and interest on the 2024 Senior Notes will become immediately due and payable without any action on the part of the Trustee or any holders of the 2024 Senior Notes. 2023 Senior Notes Redemption. On June 21, 2023 (the Redemption Date), EQM redeemed in full its remaining outstanding 4.75% Senior Notes due 2023 (the 2023 Notes) in the aggregate principal amount of $98.9 million, pursuant to the Indenture, dated as of August 1, 2014, by and between EQM, the subsidiary guarantors party thereto and The Bank of New York Mellon Trust Company, N.A. (BNYMTC), as trustee, as supplemented by that certain Third Supplemental Indenture, dated as of June 25, 2018, by and between the EQM and BNYMTC, at a redemption price equal to 100% of the principal amount of the 2023 Notes, plus accrued and unpaid interest to, but not including, the Redemption Date. Upon the redemption by EQM of the 2023 Notes, the Third Supplemental Indenture was discharged and ceased to be of further effect except as to rights thereunder. EQM utilized cash on hand to effect payment of the redemption on the Redemption Date. As of June 30, 2024, EQM and Eureka were in compliance with all debt provisions and covenants.

Fair Value Measurements	Jun. 30, 2024
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Assets Measured at Fair Value on a Recurring Basis. The Company records derivative instruments at fair value on a gross basis in its consolidated balance sheets. The Company, EQT and certain affiliates of EQT have a Gas Gathering and Compression Agreement dated February 26, 2020 (as amended, the "EQT Global GGA") which provides, among other things, for potential cash bonus payments payable by EQT to the Company during the period that began on July 1, 2024 through the calendar quarter ending December 31, 2024 (the Henry Hub cash bonus payment provision). The potential cash bonus payments are conditioned upon the quarterly average of certain Henry Hub natural gas prices exceeding certain price thresholds. The Henry Hub cash bonus payment provision is accounted for as a derivative instrument and recorded at its estimated fair value using a Monte Carlo simulation model. Significant inputs used in the fair value measurement include NYMEX Henry Hub natural gas futures prices as of the date of valuation, probability-weighted assumptions regarding MVP project completion (prior to in-service), the actual MVP in-service date, risk-free interest rates based on U.S. Treasury rates, expected volatility of NYMEX Henry Hub natural gas futures prices and an estimated credit spread of EQT. The probability-weighted assumptions regarding MVP project completion utilizing internally developed methodologies (prior to in-service), and the expected volatility of NYMEX Henry Hub natural gas futures prices, used in the valuation methodology represent significant unobservable inputs causing the Henry Hub cash bonus payment provision to be designated as a Level 3 fair value measurement. An expected average volatility of approximately 55.0% was utilized in the valuation model, which is based on market-quoted volatilities of relevant NYMEX Henry Hub natural gas forward prices. As of June 30, 2024 and December 31, 2023, the fair values of the Henry Hub cash bonus payment provision were $23.0 million and $24.5 million, respectively, which were recorded in other current assets on the Company's consolidated balance sheets. During the three and six months ended June 30, 2024, the Company recognized a gain of $3.2 million and a loss of $1.5 million, respectively, and during the three and six months ended June 30, 2023 the Company recognized gains of $19.4 million and $10.9 million, respectively, representing the change in estimated fair value of the derivative instrument during the respective periods and are recorded in other income (expense), net on the Company's statements of consolidated comprehensive income. Other Financial Instruments. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short maturity of the instruments. The carrying values of borrowings under the Amended EQM Credit Facility and the 2021 Eureka Credit Facility approximate fair value as the interest rates are based on prevailing market rates. As EQM's borrowings under its senior notes are not actively traded, their fair values are estimated using an income approach model that applies a discount rate based on prevailing market rates for debt with similar remaining time-to-maturity and credit risk; as such, their fair values are Level 2 fair value measurements. As of June 30, 2024 and December 31, 2023, the estimated fair values of EQM's senior notes were approximately $6,916.8 million and $6,334.3 million, respectively, and the carrying values of EQM's senior notes were approximately $6,943.2 million and $6,346.4 million, respectively. The fair value of the preferred interest that the Company has in EQT Energy Supply, LLC (EES), a subsidiary of EQT (the Preferred Interest) is a Level 3 fair value measurement and is estimated using an income approach model that applies a market-based discount rate. As of June 30, 2024, and December 31, 2023, the estimated fair values of the Preferred Interest were approximately $86.3 million and $90.7 million, respectively, and the carrying values of the Preferred Interest were approximately $85.4 million and $88.5 million, respectively.

The Company excluded 31,125 and 32,506 (in thousands) of weighted average anti-dilutive securities related to the Equitrans Midstream Preferred Shares and stock-based compensation awards from the computation of diluted weighted average common shares outstanding for the three and six months ended June 30, 2023. The Company grants Equitrans Midstream phantom units to non-employee directors that will be paid in Equitrans Midstream common stock upon the director's termination of service from the Company's Board of Directors. As there are no remaining service, performance or market conditions related to these awards, 901 and 871 (in thousands) Equitrans Midstream phantom units were included in the computation of basic and diluted weighted average common shares outstanding for the three and six months ended June 30, 2024, respectively and 745 and 674 (in thousands) Equitrans Midstream phantom units were included in the computation of basic and diluted weighted average common shares outstanding for the three and six months ended June 30, 2023, respectively.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate was 9.0% for the three months ended June 30, 2024 compared to 0.7% for the three months ended June 30, 2023. The Company's effective tax rate was 12.6% for the six months ended June 30, 2024 compared to (1.9)% for the six months ended June 30, 2023. The Company calculates the provision for income taxes for interim periods by applying an estimate of the annual effective tax rate for the full fiscal year to "ordinary" income or loss (income (loss) before income taxes excluding unusual or infrequently occurring items) for the periods. The effective tax rate was higher for the three and six months ended June 30, 2024 compared to the three and six months ended June 30, 2023 primarily due to the impact of changes in the valuation allowance that limit tax benefits for the Company's federal and state deferred tax assets and the impact of projected AFUDC - equity from the MVP project. The effective tax rate for the three and six months ended June 30, 2024 and for the three and six months ended June 30, 2023 was lower than the statutory rate primarily due to the impact of changes in valuation allowances that limit tax benefits for the Company’s federal and state deferred tax assets and the impact of projected AFUDC – equity from the MVP project. For the six months ended June 30, 2024, the Company believes that it is more likely than not that a portion of the benefit from the deferred tax assets related to interest disallowance carryforward under Internal Revenue Code Section 163(j) will not be realized and accordingly, the Company maintains a valuation allowance. For the six months ended June 30, 2024, the Company recorded approximately $20.2 million in income tax benefit related to changes in valuation allowances because of increases in federal and state deferred tax liabilities that are expected to be realized against net operating losses and a portion of the interest disallowance carryforward. As of June 30, 2024 and December 31, 2023, the valuation allowances related to federal and state deferred tax assets were approximately $36.6 million and $56.8 million, respectively.

Basis of Presentation	Basis of Presentation. References in these financial statements to Equitrans Midstream or the Company refer collectively to Equitrans Midstream Corporation and its consolidated subsidiaries for all periods presented, unless otherwise indicated. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial information and with the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these unaudited consolidated financial statements include all adjustments (consisting of only normal, recurring adjustments, unless otherwise disclosed in this Quarterly Report on Form 10-Q) necessary for a fair presentation of the financial position of the Company as of June 30, 2024, the results of its operations, and equity for the three and six months ended June 30, 2024 and 2023 and its cash flows for the six months ended June 30, 2024 and 2023. The consolidated balance sheet at December 31, 2023 has been derived from the audited financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2023, which includes all disclosures required by GAAP. Due to, among other things, the seasonal nature of the Company's utility customer contracts, as well as producers’ well completion activities and varying needs for fresh and produced water (which are primarily driven by horizontal lateral lengths and the number of completion stages per well), the interim statements for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. For further information, refer to the Company's consolidated financial statements and related notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, as well as Part I, "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" contained herein.
Recently Issued Accounting Standards	Recently Issued Accounting Standards. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides improvements to reportable segment disclosures and is intended to enhance the disclosures regarding significant segment expenses. The guidance is applicable to all public entities that are required to report segment information in accordance with Topic 280 and is to be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the potential impact of adopting this standard on its financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures, which provides improvements to income tax disclosures and is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The guidance is applicable to all public entities required to report income taxes in accordance with ASC 740 and should be applied prospectively, but retrospective application is permitted. The standard requires disaggregated information about a reporting entity’s effective tax rate reconciliation, information on income taxes paid, and various other disclosure changes. The Company is currently evaluating the potential impact of adopting this standard on its financial statements and related disclosures.
