EQT GP HOLDINGS, LP AND SUBSIDIARIES

Notes to Consolidated Financial Statements (Unaudited)

A. Financial Statements

Organization

EQGP owns EQT's partnership interests in EQM, a growth-oriented Delaware limited partnership. EQT Midstream Services, LLC (EQM General Partner) is a direct wholly owned subsidiary of EQGP and is the general partner of EQM. EQT GP Services, LLC (EQGP General Partner) is an indirect wholly owned subsidiary of EQT and is the general partner of EQGP.

EQGP has no independent operations or material assets other than its partnership interests in EQM. EQGP’s financial statements differ from those of EQM primarily as a result of noncontrolling interest ownership attributable to the publicly held limited partner interests in EQM and additional expenses incurred by EQGP which include selling, general and administrative expenses and net interest expense or income.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with 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 Form 10-Q) necessary for a fair presentation of the financial position of EQGP as of September 30, 2017 and December 31, 2016, the results of its operations for the three and nine months ended September 30, 2017 and 2016 and its cash flows and equity for the nine months ended September 30, 2017 and 2016. Certain previously reported amounts have been reclassified to conform to the current year presentation. The balance sheet at December 31, 2016 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

AVC, Rager and the Gathering Assets were businesses and the October 2016 Acquisition was a transaction between entities under common control; therefore, EQM recorded the assets and liabilities of these entities at their carrying amounts to EQT on the date of the transaction. The difference between EQT’s net carrying amount and the total consideration paid to EQT was recorded as a capital transaction with EQT, which resulted in a reduction in equity. EQGP recast its consolidated financial statements to retrospectively reflect the October 2016 Acquisition as if the entities were owned by EQM for all periods presented; however, the consolidated financial statements are not necessarily indicative of the results of operations that would have occurred if EQM had owned them during the periods reported.

Due to the seasonal nature of EQM’s utility customer contracts, the interim statements for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

For further information, refer to the consolidated financial statements and footnotes thereto included in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 as well as “Management's Discussion and Analysis of Financial Condition and Results of Operations” contained therein.

Recently Issued Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The standard requires an entity to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date which approved a one year deferral of ASU 2014-09 to annual reporting periods beginning after December 15, 2017. EQGP expects to adopt the ASUs using the modified retrospective method of adoption on January 1, 2018. During the third quarter of 2017, EQGP substantially completed its detailed review of the impact of the standard on each of its contracts. Based on this review, EQGP does not expect the standard to have a significant impact on net income. EQGP is currently evaluating the impact of the standard on its internal controls and disclosures.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The changes primarily affect the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. This standard

8

will eliminate the cost method of accounting for equity investments. The ASU will be effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period, with early adoption of certain provisions permitted. EQGP will adopt this standard in the first quarter of 2018 and does not expect that the adoption will have a material impact on its financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The primary effect of adopting the new standard will be to record assets and obligations for contracts currently recognized as operating leases. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The ASU will be effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with early adoption permitted. EQGP has completed a high level identification of agreements covered by this standard and will continue to evaluate the impact this standard will have on its financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. For assets held at amortized cost basis, this ASU eliminates the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. The amendments affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The ASU will be effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. EQGP is currently evaluating the impact this standard will have on its financial statements and related disclosures.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the presentation and classification of eight specific cash flow issues. The amendments in the ASU will be effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, with early adoption permitted. EQGP adopted this standard in the second quarter of 2017 with no material impact on its financial statements and related disclosures.

B. October 2016 Acquisition

Effective October 1, 2016, EQM acquired from EQT 100% of the outstanding limited liability company interests of AVC and Rager as well as the Gathering Assets. The aggregate consideration paid by EQM to EQT of $275 million was funded by borrowings under the $1 Billion Facility (as defined in Note G).

Prior to the October 2016 Acquisition, EQM operated the AVC facilities as part of its transmission and storage system under a lease agreement with EQT. The lease was a capital lease under GAAP; therefore, revenues and expenses associated with the AVC facilities were included in EQM’s historical consolidated financial statements and the AVC facilities were depreciated over the lease term of 25 years. In conjunction with the October 2016 Acquisition, the lease agreement was terminated. As a result, EQGP's recast of the consolidated financial statements included recasting depreciation expense recognized for the periods prior to the transaction to reflect the pipeline’s useful life of 40 years. The cumulative capital lease depreciation recorded for periods prior to the transaction was eliminated through equity at the time of the acquisition and the consolidated financial statements now reflect the depreciation expense based on the 40 year useful life. This adjustment increased previously reported net income by $1.8 million and $5.2 million for the three and nine months ended September 30, 2016, respectively.

C. Equity and Net Income per Limited Partner Unit

EQGP Equity. As of September 30, 2017, EQT indirectly held 239,715,000 EQGP common units, representing a 90.1% limited partner interest, and the entire non-economic general partner interest in EQGP.

Net Income per Limited Partner Unit. Net income attributable to AVC, Rager and the Gathering Assets for periods prior to October 1, 2016 was not allocated to the limited partners for purposes of calculating net income per limited partner unit.

(1) EQM accrues capital expenditures when work has been completed but the associated bills have not yet been paid. These accrued amounts are excluded from capital expenditures on the statements of consolidated cash flows until they are paid in a subsequent period. Accrued capital expenditures were approximately $26.5 million, $31.2 million and $26.7 million at September 30, 2017, June 30, 2017 and December 31, 2016, respectively. Accrued capital expenditures were approximately $48.2 million, $50.7 million and $24.1 million at September 30, 2016, June 30, 2016 and December 31, 2015, respectively.

E. Related Party Transactions 

In the ordinary course of business, EQGP and EQM engage in transactions with EQT and its affiliates. EQM has various contracts with EQT affiliates including, but not limited to, transportation service and precedent agreements, storage agreements and gas gathering agreements. EQGP and EQM each have an omnibus agreement with EQT. Pursuant to the omnibus agreements, EQT performs centralized corporate, general and administrative services for EQGP and EQM. In exchange, EQGP and EQM reimburse EQT for the expenses incurred in providing these services, including direct and indirect costs and expenses attributable to EQT's long-term incentive programs. Pursuant to an operation and management services agreement, EQT Gathering, LLC (EQT Gathering), an indirect wholly owned subsidiary of EQT, provides EQM’s pipelines and storage facilities with certain operational and management services. EQM reimburses EQT Gathering for such services pursuant to the terms of the EQM omnibus agreement. The expenses for which EQGP and EQM reimburse EQT and its subsidiaries may not necessarily reflect the actual expenses that EQGP and EQM would incur on a stand-alone basis and EQGP and EQM are unable to estimate what those expenses would be on a stand-alone basis.

F. Investment in Unconsolidated Entity

MVP Joint Venture. The MVP Joint Venture plans to construct the Mountain Valley Pipeline (MVP), an estimated 300-mile natural gas interstate pipeline spanning from northern West Virginia to southern Virginia. EQM is the operator of the MVP and owned a 45.5% interest in the MVP Joint Venture as of September 30, 2017. The MVP Joint Venture has been determined to be a variable interest entity because it has insufficient equity to finance its activities during the construction stage of the project. EQM is not the primary beneficiary because it does not have the power to direct the activities of the MVP Joint Venture that most significantly impact its economic performance. Certain business decisions require the approval of owners holding more than a 66 2/3% interest in the MVP Joint Venture and no one member owns more than a 66 2/3% interest. EQM accounts for the interest in the MVP Joint Venture as an equity method investment as EQM has the ability to exercise significant influence over operating and financial policies of the MVP Joint Venture.

In August 2017, the MVP Joint Venture issued a capital call notice to MVP Holdco, LLC (MVP Holdco), a direct wholly owned subsidiary of EQM, for $48.0 million, of which $27.2 million was paid in October 2017 and the remaining $20.8 million is expected to be paid in November 2017. The capital contribution payable has been reflected on the consolidated balance sheet as of September 30, 2017 with a corresponding increase to EQM's investment in the MVP Joint Venture.

Equity income related to EQM's portion of the MVP Joint Venture's AFUDC on construction of the MVP is reported in other income in the statements of consolidated operations and was $6.0 million and $2.7 million for the three months ended September 30, 2017 and 2016, respectively, and $15.4 million and $6.1 million for the nine months ended September 30, 2017 and 2016, respectively.

11

As of September 30, 2017, EQM had issued a $91 million performance guarantee in favor of the MVP Joint Venture to provide performance assurances for MVP Holdco's obligations to fund its proportionate share of the construction budget for the MVP. Upon the FERC’s initial release to begin construction of the MVP, EQM's guarantee will terminate. EQM will then be obligated

to issue a new guarantee in an amount equal to 33% of MVP Holdco’s proportionate share of the then remaining construction budget, less, subject to certain limits, any credit assurances issued by any affiliate of EQM under such affiliate's precedent agreement with the MVP Joint Venture.

As of September 30, 2017, EQM's maximum financial statement exposure related to the MVP Joint Venture was approximately $431 million, which consists of the investment in unconsolidated entity balance on the consolidated balance sheet as of September 30, 2017 and amounts which could have become due under EQM's performance guarantee as of that date.

The following tables summarize the unaudited condensed financial statements for the investment in unconsolidated entity accounted for under the equity method of accounting.

G. Credit Facility Borrowings

EQGP Working Capital Facility. EQGP has a Working Capital Loan Agreement with EQT (the Working Capital Facility) that provides for interest bearing loans of up to $50 million outstanding at any one time and matures on the earlier of February 18, 2019 or at least 90 days after EQT gives notice of termination. EQGP had less than $0.1 million and $0.1 million of borrowings outstanding under the Working Capital Facility as of September 30, 2017 and December 31, 2016, respectively, which were included in due to related party on the consolidated balance sheets. The maximum amounts of EQGP’s outstanding borrowings under the Working Capital Facility were $0.3 million and $0.2 million during the nine months ended September 30, 2017 and 2016, respectively, and interest was incurred at weighted average annual interest rates of approximately 2.4% and 2.0%, respectively.

EQM $1 Billion Facility. In July 2017, EQM amended and restated its credit facility to increase the borrowing capacity under the facility from $750 million to $1 billion and extend the term to July 2022. The proceeds of the loans made under the $1 Billion Facility may be used by EQM for working capital, capital expenditures, dividends, unit repurchases and other lawful corporate purposes (including purchasing assets from EQT and its subsidiaries and other third parties). Subject to certain terms and conditions, the $1 Billion Facility has an accordion feature that allows EQM to increase the available borrowings under the facility by up to an additional $500 million. EQM’s $1 Billion Facility contains various provisions that, if not complied with, could result in termination of the credit facility, require early payment of amounts outstanding or similar actions. The most significant covenants and events of default relate to maintenance of a permitted leverage ratio, limitations on transactions with affiliates, limitations on restricted payments, insolvency events, nonpayment of scheduled principal or interest payments, acceleration of and certain other defaults under other financial obligations and change of control provisions. Under the $1

12

Billion Facility, EQM is required to maintain a consolidated leverage ratio of not more than 5.00 to 1.00 (or not more than 5.50 to 1.00 for certain measurement periods following the consummation of certain acquisitions).

EQM had $105 million of borrowings outstanding on its credit facility as of September 30, 2017 and had no borrowings outstanding as of December 31, 2016. During the three and nine months ended September 30, 2017, the maximum amount of EQM's outstanding borrowings under the credit facility at any time was $177 million and the average daily balances were approximately $95 million and $32 million, respectively. Interest was incurred at a weighted average annual interest rate of approximately 2.7% for the three and nine months ended September 30, 2017. During the three and nine months ended September 30, 2016, the maximum amounts of EQM’s outstanding borrowings under the credit facility at any time were $91 million and $299 million, respectively, and the average daily balances were approximately $34 million and $67 million, respectively. Interest was incurred at weighted average annual interest rates of approximately 2.0% and 1.9% for the three and nine months ended September 30, 2016, respectively.

EQM 364-Day Facility. EQM has a $500 million, 364-day, uncommitted revolving loan agreement with EQT that matures on October 24, 2018 and will automatically renew for successive 364-day periods unless EQT delivers a non-renewal notice at least 60 days prior to the then current maturity date. Interest accrues on outstanding borrowings at an interest rate equal to the rate then applicable to similar loans under the $1 Billion Facility, or a successor revolving credit facility, less the sum of (i) the then applicable commitment fee under the $1 Billion Facility and (ii) 10 basis points.

EQM had no borrowings outstanding on the 364-Day Facility as of September 30, 2017 and December 31, 2016. During the three and nine months ended September 30, 2017, the maximum amounts of EQM’s outstanding borrowings under the credit facility at any time were $40 million and $100 million, respectively, and the average daily balances were approximately $11 million and $30 million, respectively. For the three and nine months ended September 30, 2017, interest was incurred at weighted average annual interest rates of approximately 2.4% and 2.2%, respectively.

As of September 30, 2017, EQGP and EQM were in compliance with all debt provisions and covenants.

H. Fair Value Measurements

The carrying values of cash and cash equivalents, accounts receivable, amounts due to/from related parties and accounts payable approximate fair value due to the short maturity of the instruments; these are considered Level 1 fair values. The carrying value of the credit facility borrowings approximates fair value as the interest rates are based on prevailing market rates; this is considered a Level 1 fair value. As EQM's long-term debt is not actively traded, its fair value is a Level 2 fair value measurement estimated using a standard industry income approach model which utilizes a discount rate based on market rates for debt with similar remaining time to maturity and credit risk. As of September 30, 2017 and December 31, 2016, the estimated fair value of EQM's long-term debt was approximately $1,018 million and $982 million, respectively, and the carrying value of EQM's long-term debt was approximately $987 million and $986 million, respectively. The fair value of the Preferred Interest is a Level 3 fair value measurement which is estimated using an income approach model utilizing a market-based discount rate. As of September 30, 2017 and December 31, 2016, the estimated fair value of the Preferred Interest was approximately $133 million and $132 million, respectively, and the carrying value of the Preferred Interest was approximately $120 million and $123 million, respectively.

I. Income Taxes

As a result of its limited partnership structure, EQGP is not subject to federal and state income taxes. For federal and state income tax purposes, all income, expenses, gains, losses and tax credits generated by EQGP flow through to EQGP's unitholders; accordingly, EQGP does not record a provision for income taxes.

As discussed in Note A, EQGP’s consolidated financial statements have been retrospectively recast to include the pre-acquisition results of AVC, Rager and the Gathering Assets, which were acquired by EQM effective on October 1, 2016, because the transaction was between entities under common control. Accordingly, the income tax effects associated with these operations prior to acquisition are reflected in the consolidated financial statements as they were previously part of EQT’s consolidated federal tax return.

13

J.  Consolidated Variable Interest Entity

EQGP determined EQM to be a variable interest entity. Through EQGP's ownership and control of the EQM General Partner, EQGP has the power to direct the activities that most significantly impact EQM's economic performance. In addition, through EQGP's general partner interest, IDRs and limited partner interest in EQM, EQGP has the obligation to absorb EQM's losses and the right to receive benefits from EQM in accordance with its general partner and limited partner ownership percentages and IDRs. Therefore, EQGP has a controlling financial interest in EQM, is the primary beneficiary of EQM and consolidates EQM. See Note 8 to the consolidated financial statements in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 for additional information.

EQGP's only cash-generating assets consist of its partnership interests, including the IDRs, in EQM. As a result, EQGP'sresults of operations do not differ materially from the results of operations of EQM. The risks associated with EQM's operations are discussed in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 and this Quarterly Report on Form 10-Q. See further discussion of the impact that EQGP's involvement in EQM has on EQGP's financial position, results of operations and cash flows included in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016, including the section captioned “Management's Discussion and Analysis of Financial Condition and Results of Operations.” For a discussion of related party transactions, see Note 5 of Item 8 in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 and Note E contained herein.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

EQGP's consolidated financial statements have been retrospectively recast to include the pre-acquisition results of AVC, Rager and the Gathering Assets. You should read the following discussion and analysis of financial condition and results of operations in conjunction with the consolidated financial statements, and the notes thereto, included elsewhere in this report.

CAUTIONARY STATEMENTS

Disclosures in this Quarterly Report on Form 10-Q contain certain forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended.  Statements that do not relate strictly to historical or current facts are forward-looking and usually identified by the use of words such as “anticipate,” “estimate,” “could,” “would,” “will,” “may,” “forecast,” “approximate,” “expect,” “project,” “intend,” “plan,” “believe” and other words of similar meaning in connection with any discussion of future operating or financial matters.  Without limiting the generality of the foregoing, forward-looking statements contained in this Quarterly Report on Form 10-Q include the matters discussed in the section captioned “Outlook” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the expectations of plans, strategies, objectives, and growth and anticipated financial and operational performance of EQGP, including guidance regarding EQM's gathering and transmission and storage revenue and volume growth; infrastructure programs (including the timing, cost, capacity and sources of funding with respect to gathering and transmission expansion projects); the cost, capacity, timing of regulatory approvals and anticipated in-service date of the MVP project; expansion projects in EQM's areas of operations and in areas that would provide access to new markets; asset acquisitions, including EQM's ability to complete asset acquisitions from EQT or third parties; the expected benefits to EQM of EQT's proposed acquisition of Rice Energy Inc. (Rice), including whether EQT will complete the proposed acquisition and, if so, whether it will sell Rice's remaining midstream assets to EQM; the amount and timing of distributions, including expected increases; the amounts and timing of projected capital contributions and operating and capital expenditures, including the amount of capital expenditures reimbursable by EQT; the impact of commodity prices on EQM's business; liquidity and financing requirements, including sources and availability; the effects of government regulation and litigation; and tax position. The forward-looking statements included in this Quarterly Report on Form 10-Q involve risks and uncertainties that could cause actual results to differ materially from projected results.  Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results.  EQGP has based these forward-looking statements on current expectations and assumptions about future events. While EQGP considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks and uncertainties, many of which are difficult to predict and are beyond EQGP's control. The risks and uncertainties that may affect the operations, performance and results of EQGP's and EQM's business and forward-looking statements include, but are not limited to, those set forth under Item 1A, “Risk Factors” in EQGP’s Annual Report on Form 10-K for the year ended December 31, 2016.

Any forward-looking statement speaks only as of the date on which such statement is made and EQGP does not intend to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise.

In reviewing any agreements incorporated by reference in or filed with this Quarterly Report on Form 10-Q, please remember that such agreements are included to provide information regarding the terms of such agreements and are not intended to provide any other factual or disclosure information about EQGP or EQM. The agreements may contain representations and warranties by EQGP or EQM, which should not in all instances be treated as categorical statements of fact, but rather as a way of allocating the risk to one of the parties to such agreements should those statements prove to be inaccurate. The representations and warranties were made only as of the date of the relevant agreement or such other date or dates as may be specified in such agreement and are subject to more recent developments.  Accordingly, these representations and warranties alone may not describe the actual state of affairs of EQGP or its affiliates as of the date they were made or at any other time.

EXECUTIVE OVERVIEW

For the three months ended September 30, 2017, EQM reported net income of $142.9 million compared to $133.7 million for the three months ended September 30, 2016. The increase primarily resulted from higher revenues from both gathering and transmission, which were driven mainly by affiliate and third party production development in the Marcellus Shale, and lower income taxes, partly offset by an increase in operating expenses, higher net interest expense and lower other income.

16

For the nine months ended September 30, 2017, EQM reported net income of $425.3 million compared to $402.3 million for the nine months ended September 30, 2016. The increase primarily resulted from higher revenues from both transmission and gathering, which were driven mainly by affiliate and third party production development in the Marcellus Shale, and lower income taxes, partly offset by an increase in operating expenses, higher net interest expense and lower other income.

EQM declared a cash distribution to its unitholders of $0.98 per unit on October 24, 2017, which was 5% higher than the second quarter 2017 distribution of $0.935 per unit and 20% higher than the third quarter2016 distribution of $0.815 per unit.

EQGP declared a cash distribution to its unitholders of $0.228 per unit on October 24, 2017, which was 9% higher than the second quarter 2017 distribution of $0.21 per unit and 38% higher than the third quarter2016 distribution of $0.165 per unit.

Items Affecting the Comparability of EQGP's Financial Results to Those of EQM

The following table reconciles the differences between EQM net income as reported in EQM's Quarterly Report on Form 10-Q for the three and nine months ended September 30, 2017 and 2016 and net income attributable to EQGP for the same period.

	Three Months Ended   September 30,				Nine Months Ended   September 30,
	2017		2016		2017		2016
	(Thousands)
Net income attributable to EQM	$	142,938	$	133,660	$	425,273	$	402,254
Less:
Net income attributable to EQM noncontrolling interests	75,463		72,836		231,299		223,367
Additional expenses, net	531		574		2,324		2,302
Net income attributable to EQGP	$	66,944	$	60,250	$	191,650	$	176,585

Noncontrolling Interests. The common units in EQM not held by EQGP are reflected as noncontrolling interests in the consolidated financial statements. The increases in net income attributable to EQM noncontrolling interests resulted from higher EQM net income as well as, for the nine months ended September 30, 2017 and 2016, additional noncontrolling interests outstanding as a result of EQM equity offerings during the second quarter of 2016.

Additional Expenses. EQGP incurs selling, general and administrative expenses as a result of being a publicly traded partnership separate from and in addition to similar costs incurred by EQM. EQGP also incurs interest expense under its Working Capital Facility and earns interest income on cash on hand.

Business Segment Results

Operating segments are revenue-producing components of the 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. Other income and net interest expense are managed on a consolidated basis. EQGP has presented each segment's operating income and various operational measures in the following sections. Management believes that the presentation of this information provides useful information to management and investors regarding the financial condition, results of operations and trends of segments. EQGP's two segments are the same as those of EQM as EQGP does not have any operating activities separate from those of EQM. EQGP has reconciled each segment's operating income to EQGP's consolidated operating income and net income in Note D to the consolidated financial statements.

Three Months Ended September 30, 2017 Compared to Three Months Ended September 30, 2016

Gathering revenues increased by $17.4 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016driven by third party and affiliate production development in the Marcellus Shale. EQM increased firm reservation fee revenues primarily as a result of third parties and affiliates contracting for additional firm gathering capacity on the Range Resources Corporation (Range Resources) Header Pipeline project and various affiliate wellhead gathering expansion projects. The decrease in usage fees under firm contracts was due to lower affiliate volumes in excess of firm contracted capacity. The decrease in usage fees under interruptible contracts was primarily due to the additional contracts for firm capacity.

Operating expenses increased by $4.1 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016primarily as a result of increased depreciation and amortization expense of $2.3 million due to additional assets placed in-service including those associated with the Range Resources Header Pipeline project and a Northern West Virginia Marcellus gathering system (NWV Gathering) expansion project and higher personnel costs.

Nine Months Ended September 30, 2017 Compared to Nine Months Ended September 30, 2016

Gathering revenues increased by $33.7 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016driven by third party and affiliate production development in the Marcellus Shale. EQM increased firm reservation fee revenues primarily as a result of affiliates and third parties contracting for additional firm gathering capacity on various affiliate wellhead gathering expansion projects and the Range Resources Header Pipeline project. The decrease in usage fees under firm contracts was due to lower affiliate volumes in excess of firm contracted capacity. The decrease in usage fees under interruptible contracts was primarily due to the additional contracts for firm capacity.

Operating expenses increased by $9.2 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016primarily as a result of increased depreciation and amortization expense of $5.9 million due to

Three Months Ended September 30, 2017 Compared to Three Months Ended September 30, 2016

Transmission and storage revenues increased by $13.0 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016. Firm reservation fee revenues increased due to affiliates contracting for additional firm capacity on the Ohio Valley Connector (OVC). Approximately $3.4 million of the increase was related to a FERC-approved retroactive negotiated rate adjustment for the period October 1, 2016 through June 30, 2017. The firm capacity on the OVC resulted in lower affiliate usage fees under firm contracts.

Operating expenses increased by $7.1 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016. The increases in operating and maintenance expense and depreciation and amortization expense were the result of the OVC project placed in-service in the fourth quarter of 2016. Operating and maintenance expense increased primarily due to property taxes on the OVC.

Nine Months Ended September 30, 2017 Compared to Nine Months Ended September 30, 2016

Transmission and storage revenues increased by $35.3 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. Firm reservation fee revenues increased due to affiliates and third parties contracting for additional firm capacity, primarily on the OVC, as well as higher contractual rates on existing contracts in the current year. The firm capacity on the OVC resulted in lower affiliate usage fees under firm contracts.

19

Operating expenses increased by $20.4 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. The increases in operating and maintenance expense and depreciation and amortization expense were the result of the OVC project placed in-service in the fourth quarter of 2016. Operating and maintenance expense increased primarily due to property taxes on the OVC and higher personnel costs.

Other Income Statement Items

Other income decreased by $6.6 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 primarily driven by decreased AFUDC - equity of $7.2 million associated with the OVC project placed in-service in the fourth quarter of 2016 and distributions from EES of $2.8 million for the three months ended September 30, 2016 which were recorded as other income in 2016, partly offset by higher equity income related to EQM's portion of the MVP Joint Venture's AFUDC on the MVP. Other income decreased by $11.9 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 primarily driven by decreased AFUDC - equity of $12.6 million associated with the OVC project placed in-service in the fourth quarter of 2016 and distributions from EES of $8.3 million for the nine months ended September 30, 2016 which were recorded as other income in 2016, partly offset by higher equity income related to EQM's portion of the MVP Joint Venture's AFUDC on the MVP.

Net interest expense increased by $6.6 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 primarily driven by $5.2 million of interest incurred on EQM's long-term debt issued in November 2016 and lower capitalized interest and AFUDC - debt associated with decreased spending on regulated projects, partly offset by $1.7 million of interest income recorded on distributions from EES in 2017. Net interest expense increased by $14.6 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 primarily driven by $15.5 million of interest incurred on EQM's long-term debt issued in November 2016 and lower capitalized interest and AFUDC - debt associated with decreased spending on regulated projects, partly offset by $5.1 million of interest income recorded on distributions from EES in 2017.

See Note I to the consolidated financial statements for discussion of income tax expense.

See “Investing Activities” and “EQM Capital Requirements” in the “Capital Resources and Liquidity” section below for a discussion of capital expenditures.

EQM's Non-GAAP Financial Measures

Adjusted EBITDA and distributable cash flow are non-GAAP supplemental financial measures that management and external users of EQM’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, use to assess:

• EQM’s operating performance as compared to other publicly traded partnerships in the midstream energy industry without regard to historical cost basis or, in the case of adjusted EBITDA, financing methods;

• the ability of EQM’s assets to generate sufficient cash flow to make distributions to EQM’s unitholders;

• EQM’s ability to incur and service debt and fund capital expenditures; and

• the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

EQM believes that adjusted EBITDA and distributable cash flow provide useful information to investors in assessing its financial condition and results of operations. Adjusted EBITDA and distributable cash flow should not be considered as alternatives to net income, operating income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA and distributable cash flow have important limitations as analytical tools because they exclude some, but not all, items that affect net income and net cash provided by operating activities. Additionally, because adjusted EBITDA and distributable cash flow may be defined differently by other companies in its industry, EQM’s adjusted EBITDA and distributable cash flow may not be comparable to similarly titled measures of other companies, thereby diminishing the utility of the measures. Distributable cash flow should not be viewed as indicative of the actual amount of cash that EQM has available for distributions from operating surplus or that it plans to distribute.

Reconciliation of EQM Non-GAAP Financial Measures

The following table presents a reconciliation of EQM's non-GAAP financial measures of adjusted EBITDA and distributable cash flow with the most directly comparable EQM GAAP financial measures of net income and net cash provided by operating activities as derived from EQM's Quarterly Report on Form 10-Q for the quarter ended September 30, 2017.

(1) Reflects capital lease payments due under the lease. These lease payments were generally made monthly on a one month lag prior to the October 2016 Acquisition.

(2) Adjusted EBITDA attributable to the October 2016 Acquisition prior to acquisition for the periods presented was excluded from EQM’s adjusted EBITDA calculations as these amounts were generated by AVC, Rager and the Gathering Assets prior to acquisition by EQM; therefore, the amounts could not have been distributed to EQM’s unitholders. Adjusted EBITDA attributable to the October 2016 Acquisition prior to acquisition for the three and nine months ended September 30, 2016 was calculated as net income of $0.6 million and $1.3 million, respectively, plus depreciation and amortization expense of $0.7 million and $2.1 million, respectively, plus income tax expense of $3.2 million and $10.1 million, respectively, less interest income of $0.1 million and $0.5 million, respectively, less AFUDC - equity of $0.6 million and $1.6 million, respectively.

21

Adjusted EBITDA attributable to AVC, excluding income tax expense and AFUDC - equity, was previously included in EQM's results as a result of the capital lease and was eliminated from adjusted EBITDA by subtracting the capital lease payment; therefore, there is no adjustment for AVC's adjusted EBITDA prior to acquisition other than the capital lease payments, income tax expense and AFUDC - equity. Net income for AVC including decreased depreciation expense related to the 40 year useful life of the pipeline was $6.6 million and $20.6 million for the three and nine months ended September 30, 2016, respectively (see Note B to the consolidated financial statements).

(3) Ongoing maintenance capital expenditures net of expected reimbursements excludes ongoing maintenance that EQM expects to be reimbursed or that was reimbursed by EQT under the terms of EQM's omnibus agreement of $1.7 million and $0.4 million for the three months ended September 30, 2017 and 2016, respectively, and $2.6 million and $0.6 million for the nine months ended September 30, 2017 and 2016, respectively. Additionally, it excludes ongoing maintenance attributable to AVC, Rager and the Gathering Assets prior to acquisition of $1.4 million and $6.5 million for the three and nine months ended September 30, 2016, respectively.

See “Executive Overview” above for a discussion of EQM's net income, the GAAP financial measure most directly comparable to adjusted EBITDA. EQM's adjusted EBITDA increased by $34.5 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 and $88.7 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016primarily as a result of higher operating income on increased revenues driven by production development in the Marcellus Shale and the October 2016 Acquisition, which resulted in EBITDA subsequent to the transaction being reflected in adjusted EBITDA, including the elimination of the AVC lease payment.

EQM's net cash provided by operating activities, the GAAP financial measure most directly comparable to distributable cash flow, increased by $100.2 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016. The drivers for this change are substantively the same as those for the change in EQGP's net cash provided by operating activities as discussed in “Capital Resources and Liquidity.” EQM's distributable cash flow increased by $24.7 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 and $67.5 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016mainly attributable to the increase in EQM's adjusted EBITDA partly offset by increased net interest expense and ongoing maintenance capital expenditures.

Outlook

EQGP's principal business objective is to increase the quarterly cash distribution it pays to its unitholders over time through its ownership interests in EQM. EQM's principal business objective is to increase the quarterly cash distributions that it pays to its unitholders over time while ensuring the ongoing growth of its business. EQM believes that it is well positioned to achieve growth based on the combination of its relationship with EQT and its strategically located assets, which cover portions of the Marcellus, Upper Devonian and Utica Shales that lack substantial natural gas pipeline infrastructure. EQM believes it has a competitive advantage in pursuing economically attractive organic expansion projects in its areas of operations, which EQM believes will be a key driver of growth in the future. EQM is also currently pursuing organic growth projects that are expected to provide access to markets in the Gulf Coast and Southeast regions. Additionally, EQM may acquire additional midstream assets from EQT or pursue asset acquisitions from third parties. Should EQT choose to pursue midstream asset sales, it is under no contractual obligation to offer the assets to EQM.

EQM expects that the following expansion projects will allow it to capitalize on drilling activity by EQT and third party producers:

• Affiliate Wellhead Gathering Expansion. EQM expects to invest $160 million to $180 million in 2017 on gathering expansion projects supported by EQT Production development in the Marcellus Shale, down from the second quarter 2017 estimate as a result of timing of projects. EQM expects to install approximately 30 miles of gathering pipeline and 10,000 horsepower compression in its gathering systems across northern West Virginia and southwestern Pennsylvania during 2017.

• Mountain Valley Pipeline. The MVP Joint Venture is a joint venture with affiliates of each of NextEra Energy, Inc., Consolidated Edison, Inc., WGL Holdings, Inc. and RGC Resources, Inc. EQM is the operator of the MVP and owned a 45.5% interest in the MVP Joint Venture as ofSeptember 30, 2017. The 42 inch diameter MVP has a targeted capacity of 2.0 Bcf per day and is estimated to span 300 miles extending from EQM's existing transmission and storage system in Wetzel County, West Virginia to Pittsylvania County, Virginia. As currently designed, the MVP is estimated to cost a total of $3.0 billion to $3.5 billion, excluding AFUDC, with EQM funding its proportionate share through capital contributions made to the joint venture. In 2017, EQM expects to provide capital contributions of

22

approximately $180 million to $200 million to the MVP Joint Venture, primarily in support of materials, land, engineering design, environmental work and construction activities. The MVP Joint Venture has secured a total of 2.0 Bcf per day of firm capacity commitments at 20-year terms, including a 1.29 Bcf per day firm capacity commitment by EQT, and is currently in negotiation with additional shippers who have expressed interest in the MVP project. On October 13, 2017, the FERC issued the Certificate of Public Convenience and Necessity for the project. The pipeline is targeted to be placed in-service during the fourth quarter of 2018.

• Transmission Expansion. EQM plans to invest $80 million to $90 million on transmission expansion projects in 2017 including Equitrans expansion projects and modernization projects on the AVC facilities. The AVC modernization projects primarily consist of the replacement of approximately 20 miles of pipeline.

• Supply Hub Expansion. These expansion projects are designed to increase deliverable capacity to EQM's Mobley hub, which is the origin of both the OVC and the MVP. These gathering and/or transmission projects include additional compression, pipeline looping and new header pipelines. In total, the projects are expected to add up to 1.5 Bcf per day of capacity to EQM's systems.

See further discussion of capital expenditures in the “EQM Capital Requirements” section below.

Rice Transaction. On June 19, 2017, EQT announced that it had entered into a definitive agreement to acquire Rice. Completion of the transaction is subject to the approval of both EQT shareholders and Rice stockholders, as well as certain other customary closing conditions. The special meetings of EQT shareholders and Rice stockholders are each scheduled to be held for these purposes on November 9, 2017. As part of the transaction, EQT will acquire the midstream assets currently held at Rice. EQT announced that it intends to sell these retained midstream assets to EQM through one or more drop-down transactions. In addition to the potential drop-down opportunities, EQM expects to benefit from increased organic growth opportunities due to the combination of the EQT and Rice acreage positions if the transaction is completed.

Commodity Prices. EQM’s business is dependent on the continued availability of natural gas production and reserves in its areas of operation. Low prices for natural gas, including those resulting from regional basis differentials, could adversely affect development of additional reserves and production that is accessible by EQM’s pipeline and storage assets. Lower regional natural gas prices could cause producers to determine in the future that drilling activities in areas outside of EQM’s current areas of operation are strategically more attractive to them. EQT, or third party customers on EQM's systems, may reduce capital spending in the future based on commodity prices or other factors. Unless EQM is successful in attracting and retaining unaffiliated third party customers, which accounted for 46% of transmission and storage revenues and 11% of gathering revenues for the nine months ended September 30, 2017, its ability to maintain or increase the capacity subscribed and volumes transported under service arrangements on its transmission and storage system as well as the volumes gathered on its gathering systems will be dependent on receiving consistent or increasing commitments from EQT. While EQT has dedicated acreage to EQM and has entered into long-term firm transmission and gathering contracts on EQM's systems, EQT may determine in the future that drilling in EQM's areas of operations is not economical or that drilling in areas outside of EQM's current areas of operations is strategically more attractive to it. EQT is under no contractual obligation to continue to develop its acreage dedicated to EQM.

EQGP and EQM believe the high percentage of EQM's revenues derived from reservation charges under long-term, firm contracts will help to mitigate the risk of revenue fluctuations due to changes in near-term supply and demand conditions and commodity prices. For more information see “Risks Inherent in EQM’s Business - Any significant decrease in production of natural gas in EQM’s areas of operation could adversely affect its business and operating results and reduce its cash available to make distributions” included in Item 1A, “Risk Factors” of EQGP's Annual Report on Form 10-K for the year ended December 31, 2016.

Capital Resources and Liquidity

EQGP expects its only capital requirements separate from EQM will be to provide funds for distributions or for the purchase of EQM general partner units if EQGP elects to maintain its existing general partner interest in EQM.

EQM’s principal liquidity requirements are to finance its operations, fund capital expenditures, potential acquisitions and capital contributions to the MVP Joint Venture, make cash distributions and satisfy any indebtedness obligations. EQM’s ability

23

to meet these liquidity requirements will depend on its ability to generate cash in the future as well as its ability to raise capital in banking, capital and other markets. EQM’s available sources of liquidity include cash generated from operations, borrowing under EQM's credit facilities, cash on hand, debt offerings and issuances of additional EQM partnership units.

Operating Activities

Net cash flows provided by operating activities totaled $479.6 million for the nine months ended September 30, 2017 compared to $378.0 million for the nine months ended September 30, 2016. The increase was primarily driven by the timing of working capital payments between the two periods and higher operating income for which contributing factors are discussed in the “Executive Overview” and “Business Segment Results of Operations” sections herein.

Investing Activities

Net cash flows used in investing activities totaled $324.9 million for the nine months ended September 30, 2017 compared to $541.4 million for the nine months ended September 30, 2016. The decrease was primarily attributable to decreased capital expenditures as further described in the “Capital Requirements” section herein partly offset by increased capital contributions to the MVP Joint Venture in 2017 and sales of interests in the MVP Joint Venture in 2016.

Financing Activities

Net cash used in financing activities totaled $208.2 million for the nine months ended September 30, 2017 compared to $197.4 million for the nine months ended September 30, 2016. For the nine months ended September 30, 2017, the primary uses of financing cash flows were distributions paid to EQM's noncontrolling interest unitholders and EQGP unitholders and the primary source of financing cash flows was net borrowings on EQM's credit facilities. For the nine months ended September 30, 2016, the primary uses of financing cash flows were distributions paid to EQM's noncontrolling interest unitholders and EQGP unitholders and net repayments of EQM credit facility borrowings and the primary source of financing cash flows was proceeds from the sale of EQM common units under the $750 Million ATM Program.

EQM Capital Requirements

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

	Three Months Ended   September 30,				Nine Months Ended   September 30,
	2017		2016		2017		2016
	(Thousands)
Expansion capital expenditures (1)	$	60,679	$	159,755	$	207,548	$	484,525
Maintenance capital expenditures:
Ongoing maintenance	9,760		6,064		16,804		16,400
Funded regulatory compliance	55		511		55		787
Total maintenance capital expenditures	9,815		6,575		16,859		17,187
Total capital expenditures (2)	$	70,494	$	166,330	$	224,407	$	501,712

(1) Expansion capital expenditures do not include capital contributions made to the MVP Joint Venture of $43.5 million and $35.6 million for the three months ended September 30, 2017 and 2016, respectively, and $103.4 million and $76.3 million for the nine months ended September 30, 2017 and 2016, respectively.

(2) EQM accrues capital expenditures when work has been completed but the associated bills have not yet been paid. These accrued amounts are excluded from capital expenditures on the statements of consolidated cash flows until they are paid in a subsequent period. Accrued capital expenditures were approximately $26.5 million, $31.2 million and $26.7 million at September 30, 2017, June 30, 2017 and December 31, 2016, respectively. Accrued capital expenditures were approximately $48.2 million, $50.7 million and $24.1 million at September 30, 2016, June 30, 2016 and December 31, 2015, respectively.

Expansion capital expenditures decreased by $99.1 million for the three months ended September 30, 2017 compared to the three months ended September 30, 2016 and $277.0 million for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016primarily as a result of decreased spending on the OVC project and the Range

24

Resources Header Pipeline project. The final phase of the Range Resources Header Pipeline project was placed in-service during the second quarter of 2017 and now provides total firm gathering capacity of 600 MMcf per day. EQM estimates the total project cost to be approximately $240 million with approximately $40 million to be spent in 2017. The OVC project was placed into service in the fourth quarter of 2016.

In 2017, expansion capital expenditures and capital contributions to the MVP Joint Venture are expected to be $460 million to $510 million and ongoing maintenance capital expenditures are expected to be $25 million to $30 million, net of reimbursements. EQM’s future capital investments may vary significantly from period to period based on the available investment opportunities and are expected to grow substantially in future periods for the capital contributions to the MVP Joint Venture. Maintenance related capital expenditures are also expected to vary quarter to quarter. EQM expects to fund future capital expenditures primarily through cash on hand, cash generated from operations, availability under its credit facilities, debt offerings and issuances of additional EQM partnership units. EQM does not forecast capital expenditures associated with potential projects not committed as of the filing of this Quarterly Report on Form 10-Q.

Credit Facility Borrowings

See Note G to the consolidated financial statements for discussion of the EQGP and EQM credit facilities.

EQM Security Ratings

The table below sets forth the credit ratings for debt instruments of EQM at September 30, 2017.

Rating Service	Senior Notes	Outlook
Moody’s Investors Service (Moody's)	Ba1	Stable
Standard & Poor’s Ratings Services (S&P)	BBB-	Stable
Fitch Ratings (Fitch)	BBB-	Stable

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. EQM 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 EQM’s ratings, EQM’s access to the capital markets may be limited, borrowing costs could increase, EQM may be required to provide additional credit assurances in support of commercial agreements such as joint venture agreements and construction contracts, 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. Anything below these ratings, including EQM's current credit rating of Ba1 by Moody's, is considered non-investment grade.

EQM $750 Million ATM Program

As of October 26, 2017, EQM had approximately $443 million in remaining capacity under the $750 Million ATM Program.

Distributions

See Note K to the consolidated financial statements for discussion of distributions.

Commitments and Contingencies

As of September 30, 2017, no legal or regulatory claims or proceedings were pending or, to EQGP's knowledge, threatened against EQGP.

In the ordinary course of business, various legal and regulatory claims and proceedings are pending or threatened against EQM. While the amounts claimed may be substantial, EQM is unable to predict with certainty the ultimate outcome of such claims and proceedings. EQM accrues legal and other direct costs related to loss contingencies when actually incurred. EQM has established reserves it believes to be appropriate for pending matters, and after consultation with counsel and giving appropriate consideration to available insurance, EQM believes that the ultimate outcome of any matter currently pending against it will not materially affect its business, financial condition, results of operations, liquidity or ability to make distributions to EQM unitholders, including EQGP.

25

Off-Balance Sheet Arrangements

See Note F to the consolidated financial statements for discussion of the MVP Joint Venture guarantee.

Critical Accounting Policies

EQGP’s critical accounting policies are described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in EQGP’s Annual Report on Form 10-K for the year ended December 31, 2016.  Any new accounting policies or updates to existing accounting policies as a result of new accounting pronouncements have been included in the notes to EQGP’s consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for the period ended September 30, 2017. The application of EQGP’s critical accounting policies may require management to make judgments and estimates about the amounts reflected in the consolidated financial statements.  Management uses historical experience and all available information to make these estimates and judgments.  Different amounts could be reported using different assumptions and estimates.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Changes in interest rates affect the amount of interest EQGP and EQM earn on cash, cash equivalents and short-term investments and the interest rates EQGP and EQM pay on borrowings under their credit facilities. EQM's long-term borrowings are fixed rate and thus do not expose EQM to fluctuations in its results of operations or liquidity from changes in market interest rates. Changes in interest rates do affect the fair value of EQM's fixed rate debt. See Note G to the consolidated financial statements for further discussion of EQGP's and EQM's borrowings and Note H to the consolidated financial statements for a discussion of fair value measurements. EQGP or EQM may from time to time hedge the interest on portions of their borrowings under their credit facilities in order to manage risks associated with floating interest rates.

Credit Risk

EQGP is exposed to credit risk through EQM. Credit risk is the risk that EQM may incur a loss if a counterparty fails to perform under a contract. EQM manages its exposure to credit risk associated with customers through credit analysis, credit approval, credit limits and monitoring procedures. For certain transactions, EQM may request letters of credit, cash collateral, prepayments or guarantees as forms of credit support. EQM’s FERC tariffs require tariff customers that do not meet specified credit standards to provide three months of credit support; however, EQM is exposed to credit risk beyond this three month period when its tariffs do not require its customers to provide additional credit support. For some of EQM’s more recent long-term contracts associated with system expansions, it has entered into negotiated credit agreements that provide for enhanced forms of credit support if certain credit standards are not met. EQM has historically experienced only minimal credit losses in connection with its receivables. For the nine months endedSeptember 30, 2017, approximately 87% of revenues were from investment grade counterparties. EQM is exposed to the credit risk of EQT, its largest customer. In connection with EQM's IPO in 2012, EQT guaranteed all payment obligations, up to a maximum of $50 million, due and payable to Equitrans, L.P., EQM's wholly owned FERC-regulated subsidiary, by EQT Energy, LLC, one of Equitrans, L.P.’s largest customers and a wholly owned subsidiary of EQT. The EQT guaranty will terminate on November 30, 2023 unless terminated earlier by EQT upon 10 days written notice. At September 30, 2017, EQT’s public senior debt had an investment grade credit rating.

Other Market Risks

EQM's $1 Billion Facility is underwritten by a syndicate of financial institutions, each of which is obligated to fund its pro-rata portion of any borrowings by EQM. No one lender of the 19 financial institutions in the syndicate holds more than 10% of the facility. EQM’s large syndicate group and relatively low percentage of participation by each lender is expected to limit EQM’s exposure to problems or consolidation in the banking industry.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of management of the EQGP General Partner, including the EQGP General Partner’s Principal Executive Officer and Principal Financial Officer, an evaluation of EQGP’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 of the EQGP General Partner concluded that EQGP’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 third quarter of 2017 that have materially affected, or are reasonably likely to materially affect, EQGP's internal control over financial reporting.

PART II.  OTHER INFORMATION

Item 1. Legal Proceedings

As of September 30, 2017, no legal or regulatory claims or proceedings were pending or, to EQGP's knowledge, threatened against EQGP.

In the ordinary course of business, various legal and regulatory claims and proceedings are pending or threatened against EQM. While the amounts claimed may be substantial, EQM is unable to predict with certainty the ultimate outcome of such claims and proceedings. EQM accrues legal and other direct costs related to loss contingencies when actually incurred. EQM has established reserves it believes to be appropriate for pending matters and, after consultation with counsel and giving appropriate consideration to available insurance, EQM believes that the ultimate outcome of any matter currently pending against it will not materially affect its business, financial condition, results of operations, liquidity or ability to make distributions to EQM unitholders, including EQGP.

Item 1A. Risk Factors

Information regarding risk factors is discussed in Item 1A, “Risk Factors” of EQGP’s Annual Report on Form 10-K for the year ended December 31, 2016. There have been no material changes from the risk factors previously disclosed in EQGP’s Annual Report on Form 10-K.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Financial Statements

Financial Statements

Organization

EQGP owns EQT's partnership interests in EQM, a growth-oriented Delaware limited partnership. EQT Midstream Services, LLC (EQM General Partner) is a direct wholly owned subsidiary of EQGP and is the general partner of EQM. EQT GP Services, LLC (EQGP General Partner) is an indirect wholly owned subsidiary of EQT and is the general partner of EQGP.

EQGP has no independent operations or material assets other than its partnership interests in EQM. EQGP’s financial statements differ from those of EQM primarily as a result of noncontrolling interest ownership attributable to the publicly held limited partner interests in EQM and additional expenses incurred by EQGP which include selling, general and administrative expenses and net interest expense or income.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with 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 Form 10-Q) necessary for a fair presentation of the financial position of EQGP as of September 30, 2017 and December 31, 2016, the results of its operations for the three and nine months ended September 30, 2017 and 2016 and its cash flows and equity for the nine months ended September 30, 2017 and 2016. Certain previously reported amounts have been reclassified to conform to the current year presentation. The balance sheet at December 31, 2016 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

AVC, Rager and the Gathering Assets were businesses and the October 2016 Acquisition was a transaction between entities under common control; therefore, EQM recorded the assets and liabilities of these entities at their carrying amounts to EQT on the date of the transaction. The difference between EQT’s net carrying amount and the total consideration paid to EQT was recorded as a capital transaction with EQT, which resulted in a reduction in equity. EQGP recast its consolidated financial statements to retrospectively reflect the October 2016 Acquisition as if the entities were owned by EQM for all periods presented; however, the consolidated financial statements are not necessarily indicative of the results of operations that would have occurred if EQM had owned them during the periods reported.

Due to the seasonal nature of EQM’s utility customer contracts, the interim statements for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

For further information, refer to the consolidated financial statements and footnotes thereto included in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 as well as “Management's Discussion and Analysis of Financial Condition and Results of Operations” contained therein.

Recently Issued Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The standard requires an entity to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date which approved a one year deferral of ASU 2014-09 to annual reporting periods beginning after December 15, 2017. EQGP expects to adopt the ASUs using the modified retrospective method of adoption on January 1, 2018. During the third quarter of 2017, EQGP substantially completed its detailed review of the impact of the standard on each of its contracts. Based on this review, EQGP does not expect the standard to have a significant impact on net income. EQGP is currently evaluating the impact of the standard on its internal controls and disclosures.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The changes primarily affect the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. This standard will eliminate the cost method of accounting for equity investments. The ASU will be effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period, with early adoption of certain provisions permitted. EQGP will adopt this standard in the first quarter of 2018 and does not expect that the adoption will have a material impact on its financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The primary effect of adopting the new standard will be to record assets and obligations for contracts currently recognized as operating leases. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The ASU will be effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with early adoption permitted. EQGP has completed a high level identification of agreements covered by this standard and will continue to evaluate the impact this standard will have on its financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. For assets held at amortized cost basis, this ASU eliminates the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. The amendments affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The ASU will be effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. EQGP is currently evaluating the impact this standard will have on its financial statements and related disclosures.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the presentation and classification of eight specific cash flow issues. The amendments in the ASU will be effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, with early adoption permitted. EQGP adopted this standard in the second quarter of 2017 with no material impact on its financial statements and related disclosures.

October 2016 Acquisition

Business Combinations [Abstract]

October 2016 Acquisition

October 2016 Acquisition

Effective October 1, 2016, EQM acquired from EQT 100% of the outstanding limited liability company interests of AVC and Rager as well as the Gathering Assets. The aggregate consideration paid by EQM to EQT of $275 million was funded by borrowings under the $1 Billion Facility (as defined in Note G).

Prior to the October 2016 Acquisition, EQM operated the AVC facilities as part of its transmission and storage system under a lease agreement with EQT. The lease was a capital lease under GAAP; therefore, revenues and expenses associated with the AVC facilities were included in EQM’s historical consolidated financial statements and the AVC facilities were depreciated over the lease term of 25 years. In conjunction with the October 2016 Acquisition, the lease agreement was terminated. As a result, EQGP's recast of the consolidated financial statements included recasting depreciation expense recognized for the periods prior to the transaction to reflect the pipeline’s useful life of 40 years. The cumulative capital lease depreciation recorded for periods prior to the transaction was eliminated through equity at the time of the acquisition and the consolidated financial statements now reflect the depreciation expense based on the 40 year useful life. This adjustment increased previously reported net income by $1.8 million and $5.2 million for the three and nine months ended September 30, 2016, respectively.

Investment in Unconsolidated Entity

Equity Method Investments and Joint Ventures [Abstract]

Investment in Unconsolidated Entity

Investment in Unconsolidated Entity

MVP Joint Venture. The MVP Joint Venture plans to construct the Mountain Valley Pipeline (MVP), an estimated 300-mile natural gas interstate pipeline spanning from northern West Virginia to southern Virginia. EQM is the operator of the MVP and owned a 45.5% interest in the MVP Joint Venture as of September 30, 2017. The MVP Joint Venture has been determined to be a variable interest entity because it has insufficient equity to finance its activities during the construction stage of the project. EQM is not the primary beneficiary because it does not have the power to direct the activities of the MVP Joint Venture that most significantly impact its economic performance. Certain business decisions require the approval of owners holding more than a 66 2/3% interest in the MVP Joint Venture and no one member owns more than a 66 2/3% interest. EQM accounts for the interest in the MVP Joint Venture as an equity method investment as EQM has the ability to exercise significant influence over operating and financial policies of the MVP Joint Venture.

In August 2017, the MVP Joint Venture issued a capital call notice to MVP Holdco, LLC (MVP Holdco), a direct wholly owned subsidiary of EQM, for $48.0 million, of which $27.2 million was paid in October 2017 and the remaining $20.8 million is expected to be paid in November 2017. The capital contribution payable has been reflected on the consolidated balance sheet as of September 30, 2017 with a corresponding increase to EQM's investment in the MVP Joint Venture.

Equity income related to EQM's portion of the MVP Joint Venture's AFUDC on construction of the MVP is reported in other income in the statements of consolidated operations and was $6.0 million and $2.7 million for the three months ended September 30, 2017 and 2016, respectively, and $15.4 million and $6.1 million for the nine months ended September 30, 2017 and 2016, respectively.

As of September 30, 2017, EQM had issued a $91 million performance guarantee in favor of the MVP Joint Venture to provide performance assurances for MVP Holdco's obligations to fund its proportionate share of the construction budget for the MVP. Upon the FERC’s initial release to begin construction of the MVP, EQM's guarantee will terminate. EQM will then be obligated

to issue a new guarantee in an amount equal to 33% of MVP Holdco’s proportionate share of the then remaining construction budget, less, subject to certain limits, any credit assurances issued by any affiliate of EQM under such affiliate's precedent agreement with the MVP Joint Venture.

As of September 30, 2017, EQM's maximum financial statement exposure related to the MVP Joint Venture was approximately $431 million, which consists of the investment in unconsolidated entity balance on the consolidated balance sheet as of September 30, 2017 and amounts which could have become due under EQM's performance guarantee as of that date.

The following tables summarize the unaudited condensed financial statements for the investment in unconsolidated entity accounted for under the equity method of accounting.

Credit Facility Borrowings

Debt Disclosure [Abstract]

Credit Facility Borrowings

Credit Facility Borrowings

EQGP Working Capital Facility. EQGP has a Working Capital Loan Agreement with EQT (the Working Capital Facility) that provides for interest bearing loans of up to $50 million outstanding at any one time and matures on the earlier of February 18, 2019 or at least 90 days after EQT gives notice of termination. EQGP had less than $0.1 million and $0.1 million of borrowings outstanding under the Working Capital Facility as of September 30, 2017 and December 31, 2016, respectively, which were included in due to related party on the consolidated balance sheets. The maximum amounts of EQGP’s outstanding borrowings under the Working Capital Facility were $0.3 million and $0.2 million during the nine months ended September 30, 2017 and 2016, respectively, and interest was incurred at weighted average annual interest rates of approximately 2.4% and 2.0%, respectively.

EQM $1 Billion Facility. In July 2017, EQM amended and restated its credit facility to increase the borrowing capacity under the facility from $750 million to $1 billion and extend the term to July 2022. The proceeds of the loans made under the $1 Billion Facility may be used by EQM for working capital, capital expenditures, dividends, unit repurchases and other lawful corporate purposes (including purchasing assets from EQT and its subsidiaries and other third parties). Subject to certain terms and conditions, the $1 Billion Facility has an accordion feature that allows EQM to increase the available borrowings under the facility by up to an additional $500 million. EQM’s $1 Billion Facility contains various provisions that, if not complied with, could result in termination of the credit facility, require early payment of amounts outstanding or similar actions. The most significant covenants and events of default relate to maintenance of a permitted leverage ratio, limitations on transactions with affiliates, limitations on restricted payments, insolvency events, nonpayment of scheduled principal or interest payments, acceleration of and certain other defaults under other financial obligations and change of control provisions. Under the $1 Billion Facility, EQM is required to maintain a consolidated leverage ratio of not more than 5.00 to 1.00 (or not more than 5.50 to 1.00 for certain measurement periods following the consummation of certain acquisitions).

EQM had $105 million of borrowings outstanding on its credit facility as of September 30, 2017 and had no borrowings outstanding as of December 31, 2016. During the three and nine months ended September 30, 2017, the maximum amount of EQM's outstanding borrowings under the credit facility at any time was $177 million and the average daily balances were approximately $95 million and $32 million, respectively. Interest was incurred at a weighted average annual interest rate of approximately 2.7% for the three and nine months ended September 30, 2017. During the three and nine months ended September 30, 2016, the maximum amounts of EQM’s outstanding borrowings under the credit facility at any time were $91 million and $299 million, respectively, and the average daily balances were approximately $34 million and $67 million, respectively. Interest was incurred at weighted average annual interest rates of approximately 2.0% and 1.9% for the three and nine months ended September 30, 2016, respectively.

EQM 364-Day Facility. EQM has a $500 million, 364-day, uncommitted revolving loan agreement with EQT that matures on October 24, 2018 and will automatically renew for successive 364-day periods unless EQT delivers a non-renewal notice at least 60 days prior to the then current maturity date. Interest accrues on outstanding borrowings at an interest rate equal to the rate then applicable to similar loans under the $1 Billion Facility, or a successor revolving credit facility, less the sum of (i) the then applicable commitment fee under the $1 Billion Facility and (ii) 10 basis points.

EQM had no borrowings outstanding on the 364-Day Facility as of September 30, 2017 and December 31, 2016. During the three and nine months ended September 30, 2017, the maximum amounts of EQM’s outstanding borrowings under the credit facility at any time were $40 million and $100 million, respectively, and the average daily balances were approximately $11 million and $30 million, respectively. For the three and nine months ended September 30, 2017, interest was incurred at weighted average annual interest rates of approximately 2.4% and 2.2%, respectively.

As of September 30, 2017, EQGP and EQM were in compliance with all debt provisions and covenants.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The carrying values of cash and cash equivalents, accounts receivable, amounts due to/from related parties and accounts payable approximate fair value due to the short maturity of the instruments; these are considered Level 1 fair values. The carrying value of the credit facility borrowings approximates fair value as the interest rates are based on prevailing market rates; this is considered a Level 1 fair value. As EQM's long-term debt is not actively traded, its fair value is a Level 2 fair value measurement estimated using a standard industry income approach model which utilizes a discount rate based on market rates for debt with similar remaining time to maturity and credit risk. As of September 30, 2017 and December 31, 2016, the estimated fair value of EQM's long-term debt was approximately $1,018 million and $982 million, respectively, and the carrying value of EQM's long-term debt was approximately $987 million and $986 million, respectively. The fair value of the Preferred Interest is a Level 3 fair value measurement which is estimated using an income approach model utilizing a market-based discount rate. As of September 30, 2017 and December 31, 2016, the estimated fair value of the Preferred Interest was approximately $133 million and $132 million, respectively, and the carrying value of the Preferred Interest was approximately $120 million and $123 million, respectively.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

As a result of its limited partnership structure, EQGP is not subject to federal and state income taxes. For federal and state income tax purposes, all income, expenses, gains, losses and tax credits generated by EQGP flow through to EQGP's unitholders; accordingly, EQGP does not record a provision for income taxes.

As discussed in Note A, EQGP’s consolidated financial statements have been retrospectively recast to include the pre-acquisition results of AVC, Rager and the Gathering Assets, which were acquired by EQM effective on October 1, 2016, because the transaction was between entities under common control. Accordingly, the income tax effects associated with these operations prior to acquisition are reflected in the consolidated financial statements as they were previously part of EQT’s consolidated federal tax return.

Consolidated Variable Interest Entity

Consolidated Variable Interest Entity

EQGP determined EQM to be a variable interest entity. Through EQGP's ownership and control of the EQM General Partner, EQGP has the power to direct the activities that most significantly impact EQM's economic performance. In addition, through EQGP's general partner interest, IDRs and limited partner interest in EQM, EQGP has the obligation to absorb EQM's losses and the right to receive benefits from EQM in accordance with its general partner and limited partner ownership percentages and IDRs. Therefore, EQGP has a controlling financial interest in EQM, is the primary beneficiary of EQM and consolidates EQM. See Note 8 to the consolidated financial statements in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 for additional information.

EQGP's only cash-generating assets consist of its partnership interests, including the IDRs, in EQM. As a result, EQGP'sresults of operations do not differ materially from the results of operations of EQM. The risks associated with EQM's operations are discussed in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 and this Quarterly Report on Form 10-Q. See further discussion of the impact that EQGP's involvement in EQM has on EQGP's financial position, results of operations and cash flows included in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016, including the section captioned “Management's Discussion and Analysis of Financial Condition and Results of Operations.” For a discussion of related party transactions, see Note 5 of Item 8 in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 and Note E contained herein.

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with 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 Form 10-Q) necessary for a fair presentation of the financial position of EQGP as of September 30, 2017 and December 31, 2016, the results of its operations for the three and nine months ended September 30, 2017 and 2016 and its cash flows and equity for the nine months ended September 30, 2017 and 2016. Certain previously reported amounts have been reclassified to conform to the current year presentation. The balance sheet at December 31, 2016 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

AVC, Rager and the Gathering Assets were businesses and the October 2016 Acquisition was a transaction between entities under common control; therefore, EQM recorded the assets and liabilities of these entities at their carrying amounts to EQT on the date of the transaction. The difference between EQT’s net carrying amount and the total consideration paid to EQT was recorded as a capital transaction with EQT, which resulted in a reduction in equity. EQGP recast its consolidated financial statements to retrospectively reflect the October 2016 Acquisition as if the entities were owned by EQM for all periods presented; however, the consolidated financial statements are not necessarily indicative of the results of operations that would have occurred if EQM had owned them during the periods reported.

Due to the seasonal nature of EQM’s utility customer contracts, the interim statements for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.

For further information, refer to the consolidated financial statements and footnotes thereto included in EQGP's Annual Report on Form 10-K for the year ended December 31, 2016 as well as “Management's Discussion and Analysis of Financial Condition and Results of Operations” contained therein.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The standard requires an entity to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date which approved a one year deferral of ASU 2014-09 to annual reporting periods beginning after December 15, 2017. EQGP expects to adopt the ASUs using the modified retrospective method of adoption on January 1, 2018. During the third quarter of 2017, EQGP substantially completed its detailed review of the impact of the standard on each of its contracts. Based on this review, EQGP does not expect the standard to have a significant impact on net income. EQGP is currently evaluating the impact of the standard on its internal controls and disclosures.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The changes primarily affect the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. This standard will eliminate the cost method of accounting for equity investments. The ASU will be effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period, with early adoption of certain provisions permitted. EQGP will adopt this standard in the first quarter of 2018 and does not expect that the adoption will have a material impact on its financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The primary effect of adopting the new standard will be to record assets and obligations for contracts currently recognized as operating leases. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The ASU will be effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with early adoption permitted. EQGP has completed a high level identification of agreements covered by this standard and will continue to evaluate the impact this standard will have on its financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. For assets held at amortized cost basis, this ASU eliminates the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. The amendments affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The ASU will be effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. EQGP is currently evaluating the impact this standard will have on its financial statements and related disclosures.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the presentation and classification of eight specific cash flow issues. The amendments in the ASU will be effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, with early adoption permitted. EQGP adopted this standard in the second quarter of 2017 with no material impact on its financial statements and related disclosures.
