Overview of Operations EQM Midstream Partners, LP (formerly known as EQT Midstream Partners, LP) (NYSE: EQM) is a growth-oriented limited partnership that operates, acquires and develops midstream assets in the Appalachian Basin. EQM is one of the largest natural 5 Table of Contents gas gatherers in the U.S. and holds a premier transmission footprint in the Appalachian Basin. EQM provides midstream services to its customers in Pennsylvania, West Virginia and Ohio through its three primary assets: the gathering system, which delivers natural gas from wells and other receipt points to transmission pipelines; the transmission and storage system, which delivers natural gas to local demand users and long-haul interstate pipelines for access to demand markets; and the water service system, which consists of water pipelines, impoundment facilities, pumping stations, take point facilities and measurement facilities that support well completion activities and collect flowback and produced water for recycling or disposal. EQM provides a majority of its natural gas gathering, transmission and storage services under long-term, firm contracts that generally include fixed monthly reservation fees. This contract structure enhances the stability of EQM's cash flows and limits its direct exposure to commodity price risk. For the year ended December 31, 2018 , approximately 54% of EQM's revenues were generated from firm reservation fees under long-term contracts. Based on total projected contractual revenues, including projected contractual revenues from future capacity expected from expansion projects that are not yet fully constructed for which EQM has executed firm contracts, EQM's firm gathering contracts and firm transmission and storage contracts had weighted average remaining terms of approximately 11 years and 15 years, respectively, as of December 31, 2018 . EQM's operations are focused primarily in southwestern Pennsylvania, northern West Virginia and southeastern Ohio, which are strategic locations in the natural gas shale plays known as the Marcellus, Utica and Upper Devonian Shales, respectively. These regions are also the primary operating area of EQT, EQM's largest customer. EQT accounted for approximately 74% of EQM's revenues for the year ended December 31, 2018 . The following is a map of the EQM's gathering, transmission and storage and water services operations as of December 31, 2018 . 6 Table of Contents 7 Table of Contents 2018 Highlights • • • • • • • Average daily gathering throughput volumes increased 145.6% from 2,642 Btu per day (BBtu/d) for the year ended December 31, 2017 to 6,489 BBtu/d for the year ended December 31, 2018 due largely to the acquisitions described below. EQM-RMP Merger . On April 25, 2018, EQM, RMP and certain of their affiliates executed an agreement and plan of merger, pursuant to which EQM agreed to acquire RMP and the RMP General Partner. The EQM-RMP Merger closed on July 23, 2018. RMP's natural gas gathering system includes approximately 180 miles of natural gas gathering pipelines with gathering capacity of 5.1 TBtu/d and compression capacity of approximately 85,000 horsepower. In addition, RMP's water services assets consist of approximately 140 miles of water pipelines, impoundment facilities, pumping stations, take point facilities and measurement facilities in Washington and Greene Counties, Pennsylvania, and Belmont County, Ohio. See Note 2 to the consolidated financial statements for further information. The Gulfport Transaction . On May 1, 2018, EQM acquired the remaining 25% of the outstanding limited liability company interests in Strike Force Midstream LLC (Strike Force Midstream) that it did not then own from Gulfport Midstream Holdings, LLC (Gulfport Midstream), an affiliate of Gulfport Energy Corporation, for $175 million in cash (the Gulfport Transaction). Strike Force Midstream is a Delaware limited liability company that owns and operates a natural gas gathering system consisting of approximately 67 miles of natural gas gathering pipelines and compressor stations. Drop-Down Transaction. On May 22, 2018 and effective May 1, 2018, EQM, through its wholly owned subsidiary EQM Gathering Holdings, LLC (EQM Gathering), acquired from EQT all of the outstanding limited liability company interests in each of EQM Olympus, EQM WV and Strike Force pursuant to the terms of the Contribution and Sale Agreement (the Contribution Agreement). EQM Olympus' natural gas gathering system includes approximately 85 miles of natural gas gathering pipelines and compressor stations that transport gas from wells located primarily in Belmont County, Ohio. EQM WV assets include approximately 31 miles of right-of-way assets in northern West Virginia. See Note 2 to the consolidated financial statements for further information. Senior Notes Offering. During the second quarter of 2018, EQM issued 4.75% senior notes due July 15, 2023 in the aggregate principal amount of $1.1 billion, 5.50% senior notes due July 15, 2028 in the aggregate principal amount of $850 million and 6.50% senior notes due July 15, 2048 in the aggregate principal amount of $550 million (collectively, the 2018 Senior Notes). The net proceeds were used to repay the balances outstanding under the EQM Term Loan Facility and the RMP $850 Million Facility, and the remainder was used for general partnership purposes. See Note 10 for further information. Amendment to EQM's credit facility . On October 31, 2018, EQM amended and restated its $1 billion credit facility to increase the borrowing capacity under the credit facility from $1 billion to $3 billion and extend the maturity date to October 2023. See Note 10 for further information. The Separation. On November 12, 2018, EQT effected the Separation of its upstream business, which is composed of the natural gas, oil and natural gas liquids development, production and sales and commercial operations of EQT (collectively, the Upstream Business) and its midstream business, which is composed of the separately-operated natural gas gathering, transmission and storage and water services of EQT (collectively, the Midstream Business).

Until the applicable Class B unit conversion date, the Class B units will not be entitled to receive any distributions of available cash. After the applicable Class B unit conversion date, whether or not such Class B units have 8 Table of Contents been converted into EQM common units, the Class B units will participate pro rata with the EQM common units in distributions of available cash. Furthermore, the Class B units will become convertible at the holder’s option into EQM common units immediately before a change of control of EQM. The holders of Class B Units will vote together with the holders of EQM’s common units as a single class, except that Class B Units owned by the general partner of EQM and its affiliates will be excluded from voting if EQM common units owned by such parties are excluded from voting. Holders of Class B Units will be entitled to vote as a separate class on any matter that adversely affects the rights or preferences of the Class B Units in relation to other classes of partnership interests in any material respect or as required by law. The completion of the EQM IDR Transaction is subject to certain conditions, including, among other things: (1) all required filings, consents, approvals, permits and authorizations of any governmental authority in connection with the EQM IDR Transaction having been made or obtained; (2) there being no law or injunction prohibiting the consummation of the EQM IDR Transaction; (3) subject to specified materiality standards, the accuracy of the representations and warranties of the other party; (4) compliance by the other party in all material respects with its covenants; and (5) the receipt by EQM and EQGP of certain opinions covering matters described in the partnership agreements of EQM and EQGP and in the IDR Merger Agreement with respect to the EQM IDR Transaction. The EQM IDR Transaction will be accomplished by merging a subsidiary of EQM with and into EQGP, with EQGP surviving as a wholly-owned subsidiary of EQM. EQM expects the EQM IDR Transaction to close in February 2019. After giving effect to the EQM IDR Transaction, Equitrans Gathering Holdings, LLC (Equitrans Gathering Holdings), EQM GP Corporation (EQM GP Corp) and Equitrans Midstream Holdings, LLC (EMH), each a subsidiary of Equitrans Midstream, will hold 89,505,616 , 89,536 and 27,650,303 of EQM’s common units, respectively, representing an aggregate 56.5% limited partner interest in EQM. Additionally, Equitrans Gathering Holdings, EQM GP Corp and EMH will hold 6,153,907 , 6,155 and 839,938 of Class B units, respectively, representing an aggregate 3.4% limited partner interest in EQM. In total, Equitrans Midstream expects to own, directly or indirectly, a 59.9% limited partner interest in EQM that consists of 117,245,455 EQM common units and 7,000,000 Class B units. Business Segments EQM conducts its business through three business segments: Gathering, Transmission and Water. These segments include all of EQM's operations. For discussion of the composition of the three segments, see Notes 1 and 5 to the consolidated financial statements included in "Item 8. Financial Statements and Supplementary Data." The three business segments correspond to EQM's three primary assets: the gathering system, transmission and storage system and water system. The following table summarizes the composition of EQM's operating revenue by business segment. Gathering operating revenues Transmission operating revenues Water operating revenues EQM's Assets Years Ended December 31, 2018 2017 2016 67% 26% 7% 57% 42% 1% 54% 46% —% Gathering assets . As of December 31, 2018 , EQM's gathering system included approximately 700 miles of high-pressure gathering lines with compression of approximately 333,000 horsepower and multiple interconnect points with EQM's transmission and storage system and to other interstate pipelines. EQM's gathering system also included approximately 1,500 miles of FERC-regulated, low-pressure gathering lines. Transmission and Storage assets . As of December 31, 2018 , EQM's transmission and storage system included approximately 950 miles of FERC-regulated, interstate pipeline that have interconnect points to seven interstate pipelines and LDCs. The transmission and storage system is supported by 41 compressor units, with total throughput capacity of approximately 4.4 Bcf per day and compression of approximately 120,000 horsepower, and 18 associated natural gas storage reservoirs, which have a peak withdrawal capacity of approximately 645 MMcf per day and a working gas capacity of approximately 43 Bcf . 9 Table of Contents Water assets . As of December 31, 2018 , EQM's water system included two independent systems composed of approximately 160 miles of pipeline that deliver fresh water from the Monongahela River, the Ohio River, local reservoirs and several regional waterways. In addition, as of December 31, 2018, the water system assets included 28 fresh water impoundment facilities. Strategy EQM’s assets overlay core acreage in the prolific Appalachian Basin. The location of EQM’s assets allows it to access major demand markets in the U.S. EQM is one of the largest natural gas gatherers in the U.S., and its largest customer, EQT, is the largest natural gas producer in the U.S. based on produced volumes. EQM maintains a stable cash flow profile, with over 50% of its revenue for the year ended December 31, 2018 generated by firm reservation fees. EQM’s principal strategy is to leverage its existing and planned growth projects and to seek and execute on strategically-aligned acquisition and joint venture opportunities to achieve the scale and scope of a top-tier midstream company. As part of its approach to organic growth, EQM is focused on building and completing its key gathering and transmission growth projects outlined below, many of which are supported by contracts with firm capacity commitments. Additionally, EQM expects to achieve growth from its water service business and from volumetric gathering opportunities and transmission and storage services. The water service business is complementary to the gathering business, and EQM recognizes an opportunity to expand its existing asset footprint and is actively pursuing solutions for produced water handling. EQM is also focused on optimizing and integrating its Pennsylvania gathering systems to create additional system gathering capacity and provide high- and low-pressure gathering solutions for its customers. EQM’s focus on execution of its organic projects, coupled with asset optimization efforts, disciplined capital spending and operating cost control, is complemented by EQM’s commitment to seek, evaluate and execute on strategically-aligned acquisition and joint venture opportunities. EQM believes that this approach will enable EQM to achieve its strategic goals. EQM expects that the following expansion projects will be its primary organic growth drivers: • Mountain Valley Pipeline . The MVP Joint Venture is a joint venture with EQM and affiliates of each of NextEra Energy, Inc., Con Edison, AltaGas Ltd. and RGC Resources, Inc. that is constructing the MVP. As of December 31, 2018, EQM is the operator of the MVP and owned a 45.5% interest in the MVP Joint Venture. The MVP is an estimated 300 mile, 42-inch diameter natural gas interstate pipeline with a targeted capacity of 2.0 Bcf per day that will span from EQM's existing transmission and storage system in Wetzel County, West Virginia to Pittsylvania County, Virginia, providing access to the growing southeast demand markets. As currently designed, the MVP is estimated to cost a total of approximately $4.6 billion, excluding AFUDC, of which EQM is expected to fund approximately $2.2 billion through capital contributions to the MVP Joint Venture, including approximately $65 million in excess of EQM's ownership interest. In 2019, EQM expects to make capital contributions of approximately $0.9 billion to the MVP Joint Venture, depending on the timing of the construction of the MVP and the MVP Southgate projects. The MVP Joint Venture has secured a total of 2.0 Bcf per day of firm capacity commitments at 20-year terms and is currently in negotiation with additional shippers that have expressed interest in the MVP project. The MVP Joint Venture is evaluating an expansion opportunity that could add approximately 0.5 Bcf per day of capacity through the installation of incremental compression. The MVP Joint Venture is also undertaking the MVP Southgate project and is evaluating other future pipeline extension projects. In October 2017, the FERC issued the Certificate of Public Convenience and Necessity for the MVP. In the first quarter of 2018, the MVP Joint Venture received limited notice to proceed with certain construction activities from the FERC and commenced construction. As discussed under " The regulatory approval process for the construction of new midstream assets is challenging, and recent decisions by regulatory and judicial authorities in pending proceedings could impact EQM's or the MVP Joint Venture's ability to obtain all approvals and authorizations necessary to complete certain projects on the projected time frame or at all or EQM's ability to achieve the expected investment return on the project " in "Item 1A. Risk Factors — Risks Inherent in Our Business," there are several pending challenges to certain aspects of the MVP project that must be resolved before the MVP project can be completed. The MVP Joint Venture is working to respond to the court and agency decisions and restore all permits. The MVP is targeted to be placed in service during the fourth quarter of 2019, subject to litigation and regulatory-related delay as further discussed in "Item 3. Legal Proceedings." • Wellhead Gathering Expansion and Hammerhead Project. In 2019, EQM expects to invest approximately $900 million in gathering expansion projects, including the continued gathering infrastructure expansion of core development areas in the Marcellus and Utica Shales, primarily in southwestern Pennsylvania and eastern Ohio, for EQT, Range Resources Corporation (Range Resources) and other producers, and the Hammerhead project, a 1.6 Bcf per day gathering header pipeline that is designed to connect natural gas produced in Pennsylvania and West Virginia to the MVP and is supported by a 1.2 Bcf per day firm capacity commitment from EQT. The Hammerhead project is expected to cost a total of approximately $555 million . EQM expects to invest approximately $400 million in the 10 Table of Contents Hammerhead project in 2019. The Hammerhead project is expected to be placed in service in conjunction with the MVP project in the fourth quarter of 2019. • MVP Southgate Project. In April 2018, the MVP Joint Venture announced the MVP Southgate project, a proposed 70-mile interstate pipeline that will extend from the MVP at Pittsylvania County, Virginia to new delivery points in Rockingham and Alamance Counties, North Carolina. The MVP Southgate project is backed by a 300 MMcf per day firm capacity commitment from PSNC Energy. As designed, the MVP Southgate project has expansion capabilities that could provide up to 900 MMcf per day of total capacity. The MVP Southgate project is estimated to cost a total of approximately $450 million to $500 million, which is expected to be spent primarily in 2019 and 2020. In 2019, EQM expects to provide capital contributions of approximately $40 million to the MVP Joint Venture for the MVP Southgate project. In the fourth quarter of 2018, EQM assumed a portion of Con Edison's ownership interest and purchased a portion of PSNC Energy's ownership interest in the MVP Southgate project. As a result of these transactions, EQM's ownership interest increased from 32.7% to 47.2%. As of December 31, 2018, EQM was the operator of the MVP Southgate pipeline and owned a 47.2% interest in the MVP Southgate project. The MVP Joint Venture submitted the MVP Southgate certificate application to the FERC in November 2018. Subject to approval by the FERC, the MVP Southgate project has a targeted in-service date of the fourth quarter of 2020. • • Transmission Expansion . In 2019, EQM expects to invest approximately $60 million in other transmission expansion projects, primarily attributable to the AVC, the Equitrans, L.P. Expansion project, which is designed to provide north-to-south capacity on the mainline Equitrans, L.P. system for deliveries to the MVP, and power plant projects. The Equitrans, L.P. Expansion project has a targeted in-service date of the fourth quarter of 2019. Transmission – New Power Plant Connection . EQM recently executed a precedent agreement with ESC Brooke County Power I, LLC to construct a natural gas pipeline for connection to a proposed 830-Megawatt power plant in Brooke County, West Virginia. The agreement includes a ten-year firm reservation commitment for 140 MMcf per day of capacity. EQM expects to invest an estimated $80 million to construct the approximately 16-mile pipeline, which has a targeted in-service date of mid-year 2022. • Water Expansion. In 2019, EQM expects to invest approximately $100 million in the expansion of its fresh water delivery infrastructure in Pennsylvania and Ohio. EQM recently expanded its water service relationship with EQT and entered into agreements with four other Marcellus and Utica producers. Our Relationship with Equitrans Midstream As a result of the Separation, Equitrans Midstream replaced EQT as our ultimate parent. Unlike EQT, Equitrans Midstream is a pure-play midstream company whose only cash-generating assets are its ownership interests in EQM. Markets and Customers EQM's two largest customers are EQT and its affiliates and PNG Companies LLC and its affiliates. EQT, the largest natural gas producer in the United States, accounted for approximately 74% , 74% and 75% , respectively of EQM's total revenues for the years ended December 31, 2018, 2017 and 2016 . For the years ended December 31, 2018, 2017 and 2016 , PNG Companies LLC and its affiliates, an LDC, accounted for approximately 7% , 11% and 12% , respectively, of EQM's total revenues, all of which was included in Transmission. Gathering Customers. For the year ended December 31, 2018 , EQT accounted for approximately 80% of Gathering's revenues. Subject to certain exceptions and limitations, Gathering has acreage dedications through which EQM has the right to elect to gather all natural gas produced from wells under an area covering (i) approximately 260,000 gross acres in Pennsylvania pursuant to agreements with certain affiliates of EQT and certain third parties, and (ii) approximately 176,000 gross acres in Ohio pursuant to agreements with certain affiliates of EQT and other third parties. In addition, Gathering has an acreage dedication of approximately 5,000 gross acres, with a producer option to expand towards approximately 30,000 gross acres, in Pennsylvania, pursuant to which EQM has the right to provide a proposal to gather all natural gas provided from wells under that area. EQM provides gathering services in two manners: firm service and interruptible service. Firm service contracts are typically long-term and can include firm reservation fees, which are fixed, monthly charges for the guaranteed reservation of pipeline access. As of December 31, 2018 , the gathering system had total contracted firm reservation capacity of approximately 2.4 Bcf per day. Including future capacity expected from expansion projects that are not yet fully constructed for which EQM has executed firm contracts, the gathering system had total contracted firm reservation capacity of approximately 2.7 Bcf per day as of December 31, 2018 . Volumetric-based fees can also be charged under firm contracts for each firm volume gathered as well as for volumes gathered in excess of the firm contracted volume, if system capacity exists. Based on total projected contractual 11 Table of Contents revenues, including projected contractual revenues from future capacity expected from expansion projects that are not yet fully constructed for which EQM has executed firm contracts, EQM's firm gathering contracts had a weighted average remaining term of approximately 11 years as of December 31, 2018 . Interruptible service contracts include volumetric-based fees, which are charges for the volume of natural gas gathered and generally do not guarantee access to the pipeline. These contracts can be short- or long-term. On EQM's low-pressure regulated gathering system, the typical gathering agreement provides interruptible service and has a one-year term with month-to-month rollover provisions terminable upon at least 30 days' notice. The rates for gathering service on the regulated system are based on the maximum posted tariff rate and assessed on actual receipts into the gathering system. EQM generally does not take title to the natural gas gathered for its customers but retains a percentage of wellhead gas receipts to recover natural gas used to power its compressor stations and meet other requirements on EQM's low- and high-pressure gathering systems. Transmission Customers. For the year ended December 31, 2018 , EQT accounted for approximately 62% of Transmission's throughput and approximately 54% of Transmission's revenues. Transmission has an acreage dedication from EQT through which EQM has the right to elect to transport all gas produced from wells drilled by EQT under an area covering approximately 60,000 acres in Allegheny, Washington and Greene Counties in Pennsylvania and Wetzel, Marion, Taylor, Tyler, Doddridge, Harrison and Lewis Counties in West Virginia. For the year ended December 31, 2018 , PNG Companies, LLC and its affiliates accounted for approximately 27% of Transmission's revenues. Other customers include LDCs, marketers, producers and commercial and industrial users. EQM's transmission and storage system provides customers with access to adjacent markets in Pennsylvania, West Virginia and Ohio and to the Mid-Atlantic, Northeastern, Midwestern and Gulf Coast markets through interconnect points with major interstate pipelines. EQM provides transmission and storage services in two manners: firm service and interruptible service. Firm service contracts are typically long-term and can include firm reservation fees, which are fixed, monthly charges for the guaranteed reservation of pipeline access and storage capacity. Volumetric-based fees can also be charged under firm contracts for firm volume transported or stored as well as for volumes transported or stored in excess of the firm contracted volume, if there is system capacity. Customers are not assured capacity or service for volumes in excess of the firm contracted volume as such volumes have the same priority as interruptible service. Including future capacity expected from expansion projects that are not yet fully constructed for which EQM has executed firm transmission contracts, approximately 5.0 Bcf per day of transmission capacity and 29.3 Bcf of storage capacity were subscribed under firm transmission and firm storage contracts, respectively, as of December 31, 2018 . Based on total projected contractual revenues, including projected contractual revenues from future capacity expected from expansion projects that are not yet fully constructed for which EQM has executed firm contracts, EQM's firm transmission and storage contracts had a weighted average remaining term of approximately 15 years as of December 31, 2018 . Interruptible service contracts include volumetric-based fees, which are charges for the volume of natural gas transported and generally do not guarantee access to the pipeline or storage facility. These contracts can be short- or long-term. Customers with interruptible service contracts are not assured capacity or service on the transmission and storage systems. To the extent that capacity reserved by customers with firm service contracts is not fully used or excess capacity exists, the transmission and storage systems can allocate capacity to interruptible services. EQM generally does not take title to the natural gas transported or stored for its customers. As of December 31, 2018 , approximately 86% of Transmission's contracted firm transmission capacity was subscribed by customers under negotiated rate agreements under its tariff. Approximately 10% of Transmission's contracted firm transmission capacity was subscribed at recourse rates under its tariff, which are the maximum rates an interstate pipeline may charge for its services under its tariff. The remaining 4% of Transmission's contracted firm transmission capacity was subscribed at discounted rates under its tariff, which are less than the maximum rates an interstate pipeline may charge for its services under its tariff. Water Customers . For the year ended December 31, 2018 , EQT accounted for approximately 93% of Water's revenues. EQM has the exclusive right to provide fluid handling services to certain EQT operated wells until December 22, 2029 (and thereafter such right continues on a month-to-month basis) within areas of dedication in Washington and Greene Counties, Pennsylvania and Belmont County, Ohio, including the delivery of fresh water for well completion operations and the collection and recycling or disposal of flowback and produced water. EQM also provides water services to other customers operating in the Marcellus and Utica Shales. EQM's water service revenues are primarily generated under variable price per volume contracts. The fees charged by EQM are generally tiered and, thus, are lower on a per gallon basis once certain thresholds are met. 12 Table of Contents Competition Key competitors for new natural gas gathering systems include companies that own major natural gas pipelines, independent gas gatherers and integrated energy companies. When compared to EQM or its customers, some of EQM's competitors have greater capital resources and access to, or control of, larger natural gas supplies. Competition for natural gas transmission and storage is primarily based on rates, customer commitment levels, timing, performance, commercial terms, reliability, service levels, location, reputation and fuel efficiencies. EQM's principal competitors in its transmission and storage market include companies that own major natural gas pipelines in the Marcellus, Utica and Upper Devonian Shales. In addition, EQM competes with companies that are building high-pressure gathering facilities that are able to transport natural gas to interstate pipelines without being subject to FERC jurisdiction. Major natural gas transmission companies that compete with EQM also have storage facilities connected to their transmission systems that compete with certain of EQM's storage facilities. Key competition for water services include natural gas producers that develop their own water distribution systems in lieu of employing EQM's water services assets and other natural gas midstream companies that offer water services. EQM's ability to attract customers to its water service business depends on its ability to evaluate and select suitable projects and to consummate transactions in a highly competitive environment. Regulatory Environment FERC Regulation. EQM's interstate natural gas transmission and storage operations are regulated by the FERC under the NGA, the NGPA and the Energy Policy Act of 2005. EQM's regulated system operates under tariffs approved by the FERC that establish rates, cost recovery mechanisms and the terms and conditions of service to its customers. Generally, the FERC's authority extends to: • • • rates and charges for natural gas transmission, storage and FERC-regulated gathering services; certification and construction of new interstate transmission and storage facilities; abandonment of interstate transmission and storage services and facilities; • maintenance of accounts and records; • • • • • relationships between pipelines and certain affiliates; terms and conditions of services and service contracts with customers; depreciation and amortization policies; acquisition and disposition of interstate transmission and storage facilities; and initiation and discontinuation of interstate transmission and storage services. EQM holds certificates of public convenience and necessity for its transmission and storage system issued by the FERC pursuant to Section 7 of the NGA covering rates, facilities, activities and services. These certificates require EQM to provide open-access services on its interstate pipeline and storage facilities on a not unduly discriminatory basis to all customers that qualify under the FERC gas tariffs. In addition, under Section 8 of the NGA, the FERC has the power to prescribe the accounting treatment of certain items for regulatory purposes. Thus, the books and records of EQM's interstate pipeline and storage facilities may be periodically audited by the FERC. The FERC regulates the rates and charges for transmission and storage in interstate commerce. Under the NGA, recourse rates charged by interstate pipelines must be just and reasonable. The recourse rate that EQM may charge for its services is established through the FERC's cost-of-service ratemaking process. Generally, the maximum filed recourse rates for interstate pipelines are based on the cost of providing that service including recovery of and a return on the pipeline's actual prudent historical cost of investment. Key determinants in the ratemaking process include the depreciated capital costs of the facilities, the costs of providing service, the allowed rate of return and income tax allowance, as well as volume throughput and contractual capacity commitment assumptions. On March 15, 2018, the FERC issued an order prohibiting MLP-owned pipelines from including an allowance for investor income tax liability in their cost-of-service based rates. Under its prior policy, the FERC had permitted all interstate pipelines to include an income tax allowance in the cost-of-service used as the basis for calculating their regulated recourse rates. On July 18, 2018, the FERC issued an order affirming the principal finding in the March order regarding income tax recovery and also clarifying the 13 Table of Contents treatment of Accumulated Deferred Income Taxes (ADIT) in light of the prohibition on MLP income tax allowances. Challenges to these orders are currently pending in a consolidated proceeding before the U.S. Court of Appeals for the District of Columbia Circuit. On October 17, 2018, an intervenor filed a motion to hold the proceeding in abeyance. On October 24, 2018, the FERC filed a motion to dismiss the proceeding. The court has not acted on either motion at this time. EQM cannot currently predict when the court will act on these motions. Also, on July 18, 2018, the FERC issued Order No. 849, adopting regulations requiring that natural gas pipelines submit a one-time report, Form 501-G, due in the fourth quarter of 2018. Rehearing of Order No. 849 has been requested and is currently pending before the FERC. For MLP-owned pipelines, the Form 501-G report calculates an earned rate of return on equity that attempts to identify potential cost of service of over-recovery arising from the Tax Cuts and Jobs Act, the FERC's prohibition of an income tax allowance for MLP-owned pipelines and the ADIT clarification. On December 28, 2018, Equitrans, L.P. filed its Form 501-G with the FERC. The FERC will evaluate these Form 501-G filings on a case-by-case basis and permit a limited or a general rate case initiated by pipelines, open an investigation, or take no further action. The FERC has initiated rate cases against at least four pipelines as a result of their respective Form 501-G filings. We cannot determine whether the FERC or any customer will initiate a rate case against Equitrans, L.P. as a result of its Form 501-G filing or for any other reason. The maximum applicable recourse rates and terms and conditions for service are set forth in the pipeline's FERC-approved tariff. Rate design and the allocation of costs also can affect a pipeline's profitability. While the ratemaking process establishes the maximum rate that can be charged, interstate pipelines such as EQM's transmission and storage system are permitted to discount their firm and interruptible rates without further FERC authorization down to a specified minimum level, provided they do not unduly discriminate. In addition, pipelines are allowed to negotiate different rates with their customers, as described later in this section. Changes to rates or terms and conditions of service can be proposed by a pipeline company under Section 4 of the NGA, or the existing interstate transmission and storage rates or terms and conditions of service may be challenged by a complaint filed by interested persons including customers, state agencies or the FERC under Section 5 of the NGA. Rate increases proposed by a pipeline may be allowed to become effective subject to refund and/or a period of suspension, while rates or terms and conditions of service which are the subject of a complaint under Section 5 of the NGA are subject to prospective change by the FERC. Rate increases proposed by a regulated interstate pipeline may be challenged and such increases may ultimately be rejected by the FERC. Any successful challenge against existing or proposed rates charged for EQM's transmission and storage services could have a material adverse effect on its business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to its unitholders. EQM's interstate pipeline may also use negotiated rates which could involve rates above or below the recourse rate or rates that are subject to a different rate structure than the rates specified in EQM's interstate pipeline tariffs, provided that the affected customers are willing to agree to such rates and that the FERC has approved the negotiated rate agreement. A prerequisite for allowing the negotiated rates is that negotiated rate customers must have had the option to take service under the pipeline's recourse rates. As of December 31, 2018 , approximately 86% of the system's contracted firm transmission capacity was subscribed by customers under negotiated rate agreements under its tariff. Some negotiated rate transactions are designed to fix the negotiated rate for the term of the firm transportation agreement and the fixed rate is generally not subject to adjustment for increased or decreased costs occurring during the contract term. FERC regulations also extend to the terms and conditions set forth in agreements for transmission and storage services executed between interstate pipelines and their customers. These service agreements are required to conform, in all material respects, with the form of service agreements set forth in the pipeline's FERC- approved tariff. In the event that the FERC finds that an agreement, in whole or part, is materially non-conforming, it could reject the agreement, require EQM to seek modification of the agreement or require EQM to modify its applicable tariff so that the non-conforming provisions are generally available to all customers. FERC Regulation of Gathering Rates and Terms of Service. While the FERC does not generally regulate the rates and terms of service over facilities determined to be performing a natural gas gathering function, it has traditionally regulated rates charged by interstate pipelines for gathering services performed on the pipeline's own gathering facilities when those gathering services are performed in connection with jurisdictional interstate transmission facilities. EQM maintains rates and terms of service in its tariff for unbundled gathering services performed on its gathering facilities in connection with the transmission service. Just as with rates and terms of service for transmission and storage services, EQM's rates and terms of services for its FERC-regulated low pressure gathering system may be challenged by complaint and are subject to prospective change by the FERC. Rate increases and changes to terms and conditions of service EQM proposes for its FERC- regulated low pressure gathering service may be protested, and such increases or changes can be delayed and may ultimately be rejected by the FERC. Section 1(b) of the NGA exempts certain natural gas gathering facilities from regulation by the FERC under the NGA. EQM believes that its high-pressure gathering systems meet the traditional tests the FERC has used to establish a pipeline's status as an exempt gatherer not subject to regulation as a natural gas company. However, the distinction between FERC-regulated transmission services and federally unregulated gathering services is often the subject of litigation in the industry, so the 14 Table of Contents classification and regulation of these systems are subject to change based on future determinations by the FERC, the courts or the U.S. Congress. Pipeline Safety and Maintenance. EQM's interstate natural gas pipeline system is subject to regulation by PHMSA. PHMSA has established safety requirements pertaining to the design, installation, testing, construction, operation and maintenance of gas pipeline facilities, including requirements that pipeline operators develop a written qualification program for individuals performing covered tasks on pipeline facilities and implement pipeline integrity management programs. These integrity management plans require more frequent inspections and other preventive measures to ensure safe operation of oil and natural gas transportation pipelines in HCAs, such as high population areas or facilities that are hard to evacuate and areas of daily concentrations of people. Notwithstanding the investigatory and preventative maintenance costs incurred in EQM's performance of customary pipeline management activities, EQM may incur significant additional expenses if anomalous pipeline conditions are discovered or more stringent pipeline safety requirements are implemented. For example, in April 2016, PHMSA published a notice of proposed rulemaking addressing several integrity management topics and proposing new requirements to address safety issues for natural gas transmission and gathering lines. The proposed rule would strengthen existing integrity management requirements, expand assessment and repair requirements to pipelines in areas with medium population densities and extend regulatory requirements to onshore gas gathering lines that are currently exempt. Further, in June 2016, then-President Obama signed the Protecting Our Infrastructure of Pipelines and Enhancing Safety Act of 2016 (the 2016 Pipeline Safety Act), extending PHMSA's statutory mandate under prior legislation through 2019. In addition, the 2016 Pipeline Safety Act empowered PHMSA to address imminent hazards by imposing emergency restrictions, prohibitions and safety measures on owners and operators of gas or hazardous liquid pipeline facilities without prior notice or an opportunity for a hearing and also required PHMSA to develop new safety standards for natural gas storage facilities by June 2018. Pursuant to those provisions of the 2016 Pipeline Safety Act, in October 2016 and December 2016, PHMSA issued two separate Interim Final Rules that expanded the agency's authority to impose emergency restrictions, prohibitions and safety measures and strengthened the rules related to underground natural gas storage facilities, including well integrity, wellbore tubing and casing integrity. The December 2016 Interim Final Rule, relating to underground gas storage facilities, went into effect in January 2017, with a compliance deadline in January 2018. PHMSA determined, however, that it will not issue enforcement citations to any operators for violations of provisions of the December 2016 Interim Final Rule that had previously been non-mandatory provisions of American Petroleum Institute Recommended Practices 1170 and 1171 until one year after PHMSA issues a final rule; however, no final rule has been issued. Additionally, in January 2017, PHMSA announced a new final rule regarding hazardous liquid pipelines, which increases the quality and frequency of tests that assess the condition of pipelines, requires operators to annually evaluate the existing protective measures in place for pipeline segments in HCAs, extends certain leak detection requirements for hazardous liquid pipelines not located in HCAs, and expands the list of conditions that require immediate repair. However, it is unclear when or if this rule will go into effect because, on January 20, 2017, the Trump Administration requested that all regulations that had been sent to the Office of the Federal Register, but were not yet published, be immediately withdrawn for further review. Accordingly, this rule has not become effective through publication in the Federal Register. EQM is monitoring and evaluating the effect of these and other emerging requirements on its operations. States are generally preempted by federal law in the area of pipeline safety, but state agencies may qualify to assume responsibility for enforcing federal regulations over intrastate pipelines. They may also promulgate additive pipeline safety regulations provided that the state standards are at least as stringent as the federal standards. Although many of EQM's natural gas facilities fall within a class that is not subject to integrity management requirements, EQM may incur significant costs and liabilities associated with repair, remediation, preventive or mitigation measures associated with its non-exempt transmission pipelines. The costs, if any, for repair, remediation, preventive or mitigating actions that may be determined to be necessary as a result of the testing program, as well as lost cash flows resulting from shutting down EQM's pipelines during the pendency of such actions, could be material. Should EQM fail to comply with DOT regulations adopted under authority granted to PHMSA, it could be subject to penalties and fines. PHMSA has the statutory authority to impose civil penalties for pipeline safety violations up to a maximum of approximately $200,000 per day for each violation and approximately $2 million for a related series of violations. This maximum penalty authority established by statute will continue to be adjusted periodically to account for inflation. In addition, EQM may be required to make additional maintenance capital expenditures in the future for similar regulatory compliance initiatives that are not reflected in its forecasted maintenance capital expenditures. EQM believes that its operations are in substantial compliance with all existing federal, state and local pipeline safety laws and regulations. However, the adoption of new laws and regulations, such as those proposed by PHMSA, could result in significant added costs or delays in service or the termination of projects, which could have a material adverse effect on EQM in the future. 15 Table of Contents Environmental Matters General . EQM's operations are subject to stringent federal, state and local laws and regulations relating to the protection of the environment. These laws and regulations can restrict or affect EQM's business activities in many ways, such as: • • • • requiring the acquisition of various permits to conduct regulated activities; requiring the installation of pollution-control equipment or otherwise restricting the way EQM can handle or dispose of its wastes; limiting or prohibiting construction activities in sensitive areas, such as wetlands, coastal regions or areas inhabited by endangered or threatened species; and requiring investigatory and remedial actions to mitigate or eliminate pollution conditions caused by EQM's operations or attributable to former operations. In addition, EQM's operations and construction activities are subject to county and local ordinances that restrict the time, place or manner in which those activities may be conducted so as to reduce or mitigate nuisance-type conditions, such as, for example, excessive levels of dust or noise or increased traffic congestion. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of monetary penalties, the imposition of investigatory and remedial obligations and the issuance of orders enjoining future operations or imposing additional compliance requirements. Also, certain environmental statutes impose strict, and in some cases joint and several, liability for the cleanup and restoration of sites where hydrocarbons or wastes have been disposed or otherwise released regardless of the fault of the current site owner or operator. Consequently, EQM may be subject to environmental liability at its currently owned or operated facilities for conditions caused by others prior to its involvement. EQM has implemented programs and policies designed to keep its pipelines and other facilities in compliance with existing environmental laws and regulations, and EQM does not believe that its compliance with such legal requirements will have a material adverse effect on its business, financial condition, results of operations, liquidity or ability to make quarterly cash distributions to its unitholders. Nonetheless, the trend in environmental regulation is to place more restrictions and limitations on activities that may affect the environment. Thus, there can be no assurance as to the amount or timing of future expenditures for environmental compliance or remediation, and actual future expenditures may be significantly in excess of the amounts EQM currently anticipates. For example, in October 2015, the EPA revised the NAAQS for ozone from 75 parts per billion for the current 8-hour primary and secondary ozone standards to 70 parts per billion for both standards. The EPA may designate the areas in which EQM operates as nonattainment areas. States that contain any areas designated as nonattainment areas will be required to develop implementation plans demonstrating how the areas will attain the applicable standard within a prescribed period of time. These plans may require the installation of additional equipment to control emissions. In addition, in May 2016, the EPA finalized rules that impose volatile organic compound and methane emissions limits (and collaterally reduce methane emissions) on certain types of compressors and pneumatic pumps, as well as requiring the development and implementation of leak monitoring plans for compressor stations. The EPA finalized amendments to some requirements in these standards in March 2018 and September 2018, including rescission of certain requirements and revisions to other requirements such as fugitive emissions monitoring frequency. Compliance with these or other new regulations could, among other things, require installation of new emission controls on some of EQM's equipment, result in longer permitting timelines, and significantly increase EQM's capital expenditures and operating costs, which could adversely affect EQM's business. EQM tries to anticipate future regulatory requirements that might be imposed and plan accordingly to remain in compliance with changing environmental laws and regulations and to minimize the costs of such compliance. While EQM believes that it is in substantial compliance with existing environmental laws and regulations, there is no assurance that the current conditions will continue in the future. The following is a discussion of several of the material environmental laws and regulations, as amended from time to time, that relate to EQM's business. Hazardous Substances and Waste. CERCLA and comparable state laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons who are considered to be responsible for the release of a "hazardous substance" into the environment. These persons include current and prior owners or operators of the site where a release of hazardous substances occurred and companies that transported, disposed or arranged for the transportation or disposal of the hazardous substances found at the site. Under CERCLA, these "responsible persons" may be subject to strict and joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. CERCLA also authorizes the EPA and, in some instances, third 16 Table of Contents parties to act in response to threats to the public health or the environment and to seek to recover from the responsible classes of persons the costs they incur. It is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment. EQM generates materials in the course of its ordinary operations that are regulated as "hazardous substances" under CERCLA or similar state laws and, as a result, may be jointly and severally liable under CERCLA, or such laws, for all or part of the costs required to clean up sites at which these hazardous substances have been released into the environment. EQM also generates solid wastes, including hazardous wastes, which are subject to the requirements of RCRA, and comparable state statutes. While RCRA regulates both solid and hazardous wastes, it imposes strict requirements on the generation, storage, treatment, transportation and disposal of hazardous wastes. In the ordinary course of EQM's operations, EQM generates wastes constituting solid waste and, in some instances, hazardous wastes. While certain petroleum production wastes are excluded from RCRA's hazardous waste regulations, it is possible that these wastes will in the future be designated as "hazardous wastes" and be subject to more rigorous and costly disposal requirements, which could have a material adverse effect on EQM's maintenance capital expenditures and operating expenses. EQM owns, leases or operates properties where petroleum hydrocarbons are being or have been handled for many years. EQM has generally utilized operating and disposal practices that were standard in the industry at the time, although petroleum hydrocarbons or other wastes may have been disposed of or released on or under the properties owned, leased or operated by EQM, or on or under the other locations where these petroleum hydrocarbons and wastes have been transported for treatment or disposal. In addition, certain of these properties have been operated by third parties whose treatment and disposal or release of petroleum hydrocarbons and other wastes were not under EQM's control. These properties and the wastes disposed thereon may be subject to CERCLA, RCRA and analogous state laws. Under these laws, EQM could be required to remove or remediate previously disposed wastes (including wastes disposed of or released by prior owners or operators), to clean up contaminated property (including contaminated groundwater) or to perform remedial operations to prevent future contamination. Air Emissions. The federal Clean Air Act and comparable state laws and regulations restrict the emission of air pollutants from various industrial sources, including EQM's compressor stations, and also impose various monitoring and reporting requirements. Such laws and regulations may require that EQM obtain pre-approval for the construction or modification of certain projects or facilities, obtain and strictly comply with air permits containing various emissions and operational limitations and utilize specific emission control technologies to limit emissions. EQM's failure to comply with these requirements could subject it to monetary penalties, injunctions, conditions or restrictions on operations and, potentially, criminal enforcement actions. EQM may be required to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining permits and approvals for air emissions. Compliance with these requirements may require modifications to certain of EQM's operations, including the installation of new equipment to control emissions from EQM's compressors that could result in significant costs, including increased capital expenditures and operating costs, and could adversely affect EQM's business. Climate Change. Legislative and regulatory measures to address climate change and GHG emissions are in various phases of discussion or implementation. The EPA regulates GHG emissions from new and modified facilities that are potential major sources of criteria pollutants under the Clean Air Act's Prevention of Significant Deterioration and Title V programs. The U.S. Congress, along with federal and state agencies, has considered measures to reduce the emissions of GHGs. Legislation or regulation that restricts carbon emissions could increase EQM's cost of environmental compliance by requiring EQM to install new equipment to reduce emissions from larger facilities and/or purchase emission allowances. Climate change and GHG legislation or regulation could also delay or otherwise negatively affect efforts to obtain permits and other regulatory approvals with regard to existing and new facilities or impose additional monitoring and reporting requirements. For example, in October 2015, the EPA expanded the petroleum and natural gas system sources for which annual GHG emissions reporting would be required. Additionally, several states are pursuing similar measures to regulate emissions of GHGs from new and existing sources. If implemented, such restrictions may result in additional compliance obligations with respect to, or taxes on the release, capture and use of GHGs that could have an adverse effect on EQM's operations. Conversely, legislation or regulation that sets a price on or otherwise restricts carbon emissions could also benefit EQM by increasing demand for natural gas because the combustion of natural gas results in substantially fewer carbon emissions per Btu of heat generated than other fossil fuels such as coal. The effect on EQM of any new legislative or regulatory measures will depend on the particular provisions that are ultimately adopted. Water Discharges. The federal Clean Water Act and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants or dredged and fill material into state waters as well as waters of the United States, including adjacent wetlands. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of permits issued by the EPA, the U.S. Army Corps of Engineers (U.S. Army Corps) or an analogous state agency. In September 2015, new EPA 17 Table of Contents and U.S. Army Corps rules defining the scope of the EPA's and the U.S. Army Corps' jurisdiction became effective (the 2015 Clean Water Rule). But the 2015 Clean Water Rule was promptly challenged in courts and was enjoined by judicial action in some states. Further, it has been delayed in effectiveness through agency rulemaking until February 6, 2020 nationwide. In December 2018, the EPA and the U.S. Army Corps of Engineers issued a proposed rule narrowing the scope of the Clean Water Act's jurisdiction. To the extent that any future rules expand the scope of the Clean Water Act's jurisdiction, EQM could face increased costs and delays with respect to obtaining permits for activities in jurisdictional waters, including wetlands. Spill prevention, control and countermeasure requirements of federal laws require appropriate containment berms and similar structures to help prevent the contamination of regulated waters in the event of a hydrocarbon spill, rupture or leak. In addition, the Clean Water Act and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with discharge permits or other requirements of the Clean Water Act and analogous state laws. EQM believes that compliance with existing permits and foreseeable new permit requirements will not have a material adverse effect on its business, financial condition, results of operations, liquidity or ability to make quarterly cash distributions to its unitholders. National Environmental Policy Act. The construction of interstate natural gas transportation pipelines pursuant to the NGA requires authorization from the FERC. The FERC actions are subject to the National Environmental Policy Act (NEPA). NEPA requires federal agencies, such as the FERC, to evaluate major federal actions having the potential to significantly affect the environment. In the course of such evaluations, an agency will either prepare an environmental assessment that assesses the potential direct, indirect and cumulative effects of a proposed project or, if necessary, a more detailed Environmental Impact Statement. Any proposed plans for future construction activities that require FERC authorization will be subject to the requirements of NEPA. This process has the potential to significantly delay or limit, and increase the cost of, development of midstream infrastructure. Endangered Species Act. The federal Endangered Species Act (ESA) restricts activities that may adversely affect endangered and threatened species or their habitats. Federal agencies are required to ensure that any action authorized, funded or carried out by them is not likely to jeopardize the continued existence of listed species or modify their critical habitat. While some of EQM's facilities are located in areas that are designated as habitats for endangered or threatened species, EQM believes that it is in substantial compliance with the ESA. The designation of previously unprotected species as being endangered or threatened, or the designation of previously unprotected areas as a critical habitat for such species, could cause EQM to incur additional costs, result in delays in construction of pipelines and facilities, or cause EQM to become subject to operating restrictions in areas where the species are known to exist. For example, the U.S. Fish and Wildlife Service continues to receive hundreds of petitions to consider listing additional species as endangered or threatened and is being regularly sued or threatened with lawsuits to address these petitions. Some of these legal actions may result in the listing of species located in areas in which EQM operates. Employee Health and Safety. EQM is subject to a number of federal and state laws and regulations, including the federal Occupational Safety and Health Act (OSHA) and comparable state statutes, whose purpose is to protect the health and safety of workers. In addition, the OSHA hazard communication standard, the EPA community "right-to-know" regulations and comparable state laws and regulations require that information be maintained concerning hazardous materials used or produced in EQM's operations and that this information be provided to employees, state and local government authorities and citizens. EQM believes that it is in substantial compliance with all applicable laws and regulations relating to worker health and safety. Seasonality Weather affects natural gas demand for power generation and heating purposes. Peak demand for natural gas typically occurs during the winter months as a result of the heating load. Insurance In the Predecessor period, EQM generally shared insurance coverage with EQT. Subsequent to the Separation, EQM generally shares insurance coverage with Equitrans Midstream. EQM reimburses Equitrans Midstream for the cost of the insurance pursuant to the terms of the ETRN Omnibus Agreement. The insurance program includes excess liability insurance, auto liability insurance, workers' compensation insurance and property insurance. In addition, EQM has procured separate general liability and directors and officers liability policies. All insurance coverage is in amounts management believes to be reasonable and appropriate. 18 Table of Contents Employees EQM does not have any employees. EQM is managed by the directors and officers of EQM Midstream Services, LLC, the general partner of EQM (EQM General Partner). Following the completion of the EQM IDR Transaction, EQM will be managed by the same directors and officers, except that those directors and officers will be directors and officers of EQGP Services, LLC, the then general partner of EQM (Post-IDR Transaction EQM General Partner). All executive management personnel of the EQM General Partner are officers of Equitrans Midstream and devote their time to EQM's business and affairs that is required to manage and conduct its operations. The daily business operations of EQM are conducted by employees of Equitrans Midstream and its subsidiaries. Under the terms of the ETRN Omnibus Agreement, EQM reimburses Equitrans Midstream for the provision of general and administrative services for its benefit, for direct expenses incurred by Equitrans Midstream on EQM's behalf and for expenses allocated to EQM as a result of it being a public entity. Additionally, EQM has a secondment agreement with Equitrans Midstream whereby Equitrans Midstream and its subsidiaries provide seconded employees to perform certain operating and other services with respect to EQM's business. Prior to the Separation, the daily business operations of EQM were conducted by employees of EQT and its subsidiaries. EQM reimbursed EQT for the provision of general and administrative services for its benefit, for direct expenses incurred by EQT on EQM's behalf and for expenses allocated to EQM as a result of it being a public entity. See Note 6 for further discussion. Availability of Reports EQM makes certain filings with the SEC, including its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and all amendments and exhibits to those reports, available free of charge through its website, www.eqm-midstreampartners.com, as soon as reasonably practicable after they are filed with or furnished to the SEC. The filings are also available at the SEC's Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549, by calling 1-800-SEC-0330 and on the SEC's website at www.sec.gov. Jurisdiction and Year of Formation EQM Midstream Partners, LP (formerly EQT Midstream Partners, LP) is a Delaware limited partnership formed in January 2012. Item 1A. Risk Factors In addition to the other information contained in this Annual Report on Form 10-K, the following risk factors should be considered in evaluating our business and future prospects. The following discussion of risk factors contains forward-looking statements. These risk factors may be important for understanding any statement in this Annual Report on Form 10-K or elsewhere. The following information should be read in conjunction with "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operation" and the financial statements and accompanying notes included in " Item 8. Financial Statements and Supplementary Data ." Note that additional risks not presently known to us or that are currently considered immaterial may also have a negative impact on our business and operations. If any of the events or circumstances described below actually occurs, our business, financial condition, results of operations, liquidity or ability to pay distributions could suffer and the trading price of our common units could decline. Because of the following factors, as well as other variables affecting our results of operations, past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. Risks Inherent in Our Business We depend on EQT for a substantial majority of our revenues and future growth . For example, our water service business is directly associated with EQT's well completion activities and water needs, which are partially driven by horizontal lateral lengths and the number of completion stages per well . Therefore, we are subject to the business risks of EQT , and any further decrease in EQT's drilling or completion activity could adversely affect our business and operating results . We have no control over EQT's business decisions and operations, and EQT is under no obligation to adopt a business strategy that favors us. Historically, we have provided a substantial percentage of our natural gas gathering, transmission and storage and water services to EQT. EQT accounted for approximately 74% of our revenues for the year ended December 31, 2018. We expect to derive a substantial majority of our revenues from EQT for the foreseeable future. For example, our ability to maintain water service revenues is substantially dependent on continued completion activity by EQT and other customers over time, including the volume of fresh water it distributes and produced water it handles for customers. Our fresh water distribution services, which make up a substantial portion of its water service revenues, will be in greatest demand in connection with completion 19 Table of Contents activities. To the extent that EQT or other fresh water distribution customers complete fewer wells, or wells with shorter lateral lengths, the demand for our fresh water distribution services would be reduced from that needed for more wells and longer lateral lengths. In addition, our fresh water distribution business is dependent upon active development in our areas of operation. In order to maintain or increase throughput levels on our fresh water distribution systems, we must service new wells. If reductions in development activity result in our inability to maintain the current levels of throughput on our water services, or if reductions in lateral lengths result in a decrease in demand for our water services on a per well basis, those reductions could adversely affect our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Therefore, any event, whether in our areas of operations or otherwise, that adversely affects EQT's production, financial condition, leverage, results of operations or cash flows may adversely affect our ability to sustain or increase cash distributions to our unitholders. Accordingly, we are subject to the business risks of EQT, including the following: • • • • • • • • • • • • • • • prevailing and projected natural gas, NGLs and oil prices; the proximity, capacity, cost and availability of gathering and transportation facilities, and other factors that result in differentials to benchmark prices; natural gas price volatility or a sustained period of lower commodity prices may have an adverse effect on EQT's drilling operations, revenue, profitability, future rate of growth , credit worthiness and liquidity; a further reduction in or slowing of EQT's anticipated drilling and production schedule, which would directly and adversely impact demand for our services; the costs of producing natural gas and the availability and costs of drilling rigs and crews and other equipment; infrastructure capacity constraints and interruptions; geologic considerations; risks associated with the operation of EQT's wells and facilities, including potential environmental liabilities; the availability and cost of capital on a satisfactory economic basis to fund EQT's operations; EQT's ability to identify exploration, development and production opportunities based on market conditions; uncertainties inherent in projecting future rates of production , levels of reserves, and demand for natural gas, NGLs and oil ; EQT's ability to develop additional reserves that are economically recoverable, to optimize existing well production and to sustain production; adverse effects of governmental and environmental regulation, including the availability of drilling permits, the regulation of hydraulic fracturing, the potential removal of certain federal income tax deductions with respect to natural gas and oil exploration and development or additional state taxes on natural gas extraction, changes in tax laws and negative public perception regarding EQT's operations; the loss of key personnel; and risk associated with cyber security threats. On January 22, 2019, EQT publicly announced a 2019 capital expenditure forecast of $1.9 billion to $2.0 billion, compared to 2018 capital expenditures of $2.4 billion. EQT may further reduce its capital spending in the future based on commodity prices or other factors. Unless we are successful in attracting significant new customers, our ability to maintain or increase the capacity subscribed and volumes transported under service arrangements on our gathering , transmission and storage and water systems will be dependent on receiving consistent or increasing commitments from EQT. While EQT has dedicated certain acreage to, and executed long-term firm gathering and transmission contracts on, our systems, it may determine in the future that drilling in areas outside of our current areas of operations is strategically more attractive to it and it is under no contractual obligation to maintain its production dedicated to us. Moreover, in connection with the Separation, EQT previously disclosed publicly that EQT's strategy was transitioning from one focused on volume growth to one focused on capital efficiency and free cash flow generation and that EQT was evaluating the long-term pace of development of its Upstream Business in order to achieve the optimal balance between free cash flow generation and volume growth. Based on this evaluation and as EQT publicly disclosed, EQT is currently targeting mid-single digit annual production growth over the next five years. A reduction in 20 Table of Contents the capacity subscribed or volumes transported or gathered on our systems by EQT could have a material adverse effect on our business, financial condition, results of operations, liquidity and our ability to make quarterly cash distributions to our unitholders. EQT may also elect to reduce its drilling activity if commodity prices decrease. Fluctuations in energy prices can also greatly affect the development of EQT's reserves. In general terms, the prices of natural gas, oil and other hydrocarbon products fluctuate in response to changes in supply and demand, market uncertainty and a variety of additional factors that are beyond our control. These factors include worldwide economic conditions, weather conditions and seasonal trends, the levels of domestic production and consumer demand, the levels of imported and exported natural gas, oil and LNG, the availability of transportation systems with adequate capacity, the volatility and uncertainty of regional pricing differentials, the price and availability of alternative fuels, the effect of energy conservation measures, the nature and extent of governmental regulation and taxation, and the anticipated future prices of natural gas, oil, LNG and other commodities. Declines in commodity prices could have a negative impact on EQT's development and production activity, and if sustained, could lead to a material decrease in such activity. Sustained reductions in development or production activity in our areas of operation could lead to reduced utilization of our services, which could adversely affect our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Due to these and other factors, even if reserves are known to exist in areas serviced by our assets, producers have chosen, and may choose in the future, not to develop those reserves. The amount of cash we have available for distribution to unitholders depends primarily on our cash flow rather than on our profitability, which may prevent us from making distributions, even during periods in which we record net income. The amount of cash we have available for distribution depends primarily upon our cash flow and not solely on profitability, which will be affected by non-cash items. As a result, we may make cash distributions during periods when we record losses for financial accounting purposes and may not make cash distributions during periods when we record net earnings for financial accounting purposes. In order to pay the announced fourth quarter 2018 distribution of $1.13 per unit, or $4.40 per unit on an annualized basis, we will require available cash (as defined in Note 8 to the consolidated financial statements) of approximately $211.3 million per quarter, or $753.2 million per year, based on the number of common and general partner units and the IDRs outstanding at December 31, 2018. We may not have sufficient available cash each quarter to enable us to pay the quarterly cash distribution. The amount of cash we can distribute on our units principally depends upon the amount of cash we generate from our operations, which will fluctuate from quarter to quarter based on, among other things: • • • • • • • • • • the rates we charge for our gathering, transmission and storage services; the level of firm gathering, transmission and storage capacity sold and volumes of natural gas we gather, transport and store for our customers; regional, domestic and foreign supply and perceptions of supply of natural gas; the level of demand and perceptions of demand in our end-use markets; and actual and anticipated future prices of natural gas and other commodities (and the volatility thereof), which may impact our ability to renew and replace firm gathering, transmission and storage agreements; the effect of seasonal variations in temperature on the amount of natural gas that we gather, transport and store; the level of competition from other midstream energy companies in our geographic markets; the creditworthiness of our customers; restrictions contained in our joint venture agreements; the level of our operating, maintenance and general and administrative costs; regulatory action affecting the supply of, or demand for, natural gas, the rates we can charge on our assets, how we contract for services, our existing contracts, our operating costs or our operating flexibility; and prevailing economic conditions. In addition, the actual amount of cash we will have available for distribution will depend on other factors, including: • the level and timing of capital expenditures we make; 21 Table of Contents • • • • • • • • the level of our operating and general and administrative expenses, including reimbursements to our general partner and its affiliates, including Equitrans Midstream, for services provided to us; the cost of our acquisitions, if any; our debt service requirements and other liabilities; fluctuations in our working capital needs; our ability to borrow funds and access capital markets on satisfactory terms; restrictions on distributions contained in our debt agreements; the amount of cash reserves established by our general partner; and other business risks affecting our cash levels. The demand for the services provided by our water distribution business could decline as a result of several factors. Our water service business includes fresh water distribution for use in our customers' natural gas, NGLs and oil exploration and production activities. Water is an essential component of natural gas, NGLs and oil production during the drilling, and in particular, the hydraulic fracturing process. As a result, the demand for our fresh water distribution and produced water handling services is tied to the level of drilling and completion activity of our customers, including EQT, which is currently and anticipated to continue to be our primary customer for such services. More specifically, the demand for our water distribution and produced water handling services could be adversely affected by any further reduction in or slowing of EQT's or other customers' well completions, any reduction in produced water attributable to completion activity, or the extent to which EQT or other customers complete wells with shorter lateral lengths, which would lessen the volume of fresh water required for completion activity. In addition, increased regulation of hydraulic fracturing could result in reductions or delays in natural gas, NGLs and oil production by our water service customers, which could reduce the number of wells for which we provide water services. The availability of our water supply may be limited due to reasons including, but not limited to, prolonged drought or regulatory delays associated with infrastructure development. Restrictions on the ability to obtain water or changes in wastewater disposal requirements may incentivize water recycling efforts by oil and natural gas producers, which could decrease the demand for our fresh water distribution services. Our natural gas gathering, transmission and storage services are subject to extensive regulation by federal, state and local regulatory authorities. Changes or additional regulatory measures adopted by such authorities could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make distributions. Our interstate natural gas transmission and storage operations are regulated by the FERC under the NGA, the NGPA and the Energy Policy Act of 2005. Certain portions of our gathering operations are also rate-regulated by the FERC in connection with our interstate transmission operations. Our FERC-regulated systems operate under tariffs approved by the FERC that establish rates, cost recovery mechanisms and terms and conditions of service to our customers. Generally, the FERC's authority extends to: • • • rates and charges for natural gas transmission and storage and FERC-regulated gathering services; certification and construction of new interstate transmission and storage facilities; abandonment of interstate transmission and storage services and facilities; • maintenance of accounts and records; • • • • • relationships between pipelines and certain affiliates; terms and conditions of services and service contracts with customers; depreciation and amortization policies; acquisitions and dispositions of interstate transmission and storage facilities; and initiation and discontinuation of interstate transmission and storage services. 22 Table of Contents Interstate pipelines may not charge rates or impose terms and conditions of service that, upon review by the FERC, are found to be unjust and unreasonable or unduly discriminatory. The recourse rate that may be charged by our interstate pipeline for its transmission and storage services is established through the FERC's ratemaking process. The maximum applicable recourse rate and terms and conditions for service are set forth in our FERC-approved tariffs. Pursuant to the NGA, existing interstate transmission and storage rates and terms and conditions of service may be challenged by complaint and are subject to prospective change by the FERC. Additionally, rate increases and changes to terms and conditions of service proposed by a regulated interstate pipeline may be protested and such increases or changes can be delayed and may ultimately be rejected by the FERC. We currently hold authority from the FERC to charge and collect (i) "recourse rates," which are the maximum rates an interstate pipeline may charge for its services under its tariff, (ii) "discount rates," which are rates below the "recourse rates" and above a minimum level, (iii) "negotiated rates," which involve rates above or below the "recourse rates," provided that the affected customers are willing to agree to such rates and that the FERC has approved the negotiated rate agreement, and (iv) market-based rates for some of our storage services from which we derive a small portion of our revenues. As of December 31, 2018, approximately 86% of the contracted firm transmission capacity our system was committed under such "negotiated rate" contracts, rather than recourse, discount or market rate contracts. There can be no guarantee that we will be allowed to continue to operate under such rate structures for the remainder of those assets' operating lives. Any successful challenge against rates charged for our transmission and storage services could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. While the FERC does not generally regulate the rates and terms of service over facilities determined to be performing a natural gas gathering function, the FERC has traditionally regulated rates charged by interstate pipelines for gathering services performed on the pipeline's own gathering facilities when those gathering services are performed in connection with jurisdictional interstate transmission facilities. We maintain rates and terms of service in our tariff for unbundled gathering services performed on a portion of our gathering facilities that are connected to our transmission and storage system. Just as with rates and terms of service for transmission and storage services, our rates and terms of services for our FERC-regulated gathering services may be challenged by complaint and are subject to prospective change by the FERC. Rate increases and changes to terms and conditions of service which we propose for our FERC-regulated gathering services may be protested, and such increases or changes can be delayed and may ultimately be rejected by the FERC. The FERC's jurisdiction extends to the certification and construction of interstate transmission and storage facilities, including, but not limited to, acquisitions, facility maintenance, expansions, and abandonment of facilities and services. While the FERC exercises jurisdiction over the rates and terms of service for our FERC-regulated gathering services, these gathering facilities are not subject to the FERC's certification and construction authority. Prior to commencing construction of new or existing interstate transmission and storage facilities, an interstate pipeline must obtain a certificate authorizing the construction, or file to amend its existing certificate, from the FERC. On April 19, 2018, the FERC issued a Notice of Inquiry seeking information regarding whether, and if so how, it should revise its approach under its currently effective policy statement on the certification of new natural gas transportation facilities. The formal comment period in this proceeding closed on July 25, 2018. We cannot currently predict when the FERC will issue an order in the Notice of Inquiry proceeding or what action the FERC may take in any such order. If the FERC changes its existing certificate policy, it could impact our ability to construct interstate pipeline facilities. Further, typically a significant expansion project requires review by a number of governmental agencies, including state and local agencies, whose cooperation is important in completing the regulatory process on schedule. Any agency's delay in the issuance of, or refusal to issue, authorizations or permits for one or more of these projects may mean that we will not be able to pursue these projects or that they will be constructed in a manner or with capital requirements that we did not anticipate. Such delays, refusals or resulting modifications to projects could materially and negatively impact the revenues and costs expected from these projects or cause us to abandon planned projects. FERC regulations also extend to the terms and conditions set forth in agreements for transmission and storage services executed between interstate pipelines and their customers. These service agreements are required to conform, in all material respects, with the forms of service agreements set forth in the pipeline's FERC- approved tariff. Non-conforming agreements must be filed with, and accepted by, the FERC. In the event that the FERC finds that an agreement is materially non- conforming, in whole or in part, it could reject the agreement or require us to seek modification, or alternatively require us to modify our tariff so that the non- conforming provisions are generally available to all customers. On March 15, 2018, the FERC issued an order prohibiting master limited partnership (MLP)- owned pipelines from including an allowance for investor income tax liability in their cost-of-service based rates. Under its prior policy, the FERC had permitted all interstate pipelines to include an income tax allowance in the cost- of-service used as the basis for calculating their regulated rates. On July 18, 2018, the FERC issued an order affirming the principal finding in the March order regarding income tax recovery and also clarifying the treatment of ADIT in light of the prohibition on MLP income tax allowances. Challenges to these orders are currently pending in a consolidated proceeding before the U.S. Court of Appeals for the District 23 Table of Contents of Columbia Circuit. On October 17, 2018, an intervenor filed a motion to hold the proceeding in abeyance. On October 24, 2018, the FERC filed a motion to dismiss the proceeding. The court has not acted on either motion at this time. We cannot currently predict when the court will act on these motions or the broader proceeding, or what actions the court may take. Also, on July 18, 2018, the FERC issued Order No. 849, adopting regulations requiring that natural gas pipelines must make a one-time report, Form 501-G, due in the fourth quarter of 2018. For MLP-owned pipelines, the Form 501-G report must calculate an earned rate of return on equity that addresses any potential over-recovery of their cost of service arising from the prohibition of the income tax allowance and the ADIT clarification. On December 28, 2018, Equitrans, L.P. filed its Form 501-G with the FERC. The FERC will evaluate these Form 501-G filings on a case-by-case basis and may open a limited or a general rate case, open an investigation, or take no further action. The FERC has initiated rate cases against at least four pipelines as a result of their respective Form 501-G filings. We cannot determine whether the FERC or any customer will initiate a rate case against Equitrans, L.P. as a result of its Form 501-G filing or for any other reason. Rehearing of Order No. 849 has been requested and is currently pending before the FERC. We cannot currently predict when the FERC will issue an order on rehearing in this proceeding or what action the FERC may take in any such order. This recent action by the FERC could adversely affect our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to unitholders, including us. The FERC may not continue to pursue its approach of pro-competitive policies as it considers matters such as interstate pipeline rates and rules and policies that may affect rights of access to natural gas transmission capacity and transmission and storage facilities. Section 1(b) of the NGA exempts certain natural gas gathering facilities from regulation by the FERC under the NGA. We believe that our high-pressure natural gas gathering pipelines meet the traditional tests the FERC has used to establish a pipeline's status as an exempt gatherer not subject to regulation as a natural gas company, although the FERC has not made a formal determination with respect to the jurisdictional status of those facilities. However, the distinction between FERC-regulated transmission services and federally unregulated gathering services is often the subject of litigation within the industry, so the classification and regulation of our high-pressure gathering systems are subject to change based on future determinations by the FERC, the courts or the U.S. Congress. Failure to comply with applicable provisions of the NGA, the NGPA, federal pipeline safety laws and certain other laws, as well as with the regulations, rules, orders, restrictions and conditions associated with these laws, could result in the imposition of administrative and criminal remedies and civil penalties. For example, the FERC is authorized to impose civil penalties of up to approximately $1.2 million per violation, per day for violations of the NGA, the NGPA or the rules, regulations, restrictions, conditions and orders promulgated under those statutes. This maximum penalty authority established by statute will continue to be adjusted periodically for inflation. In addition, future federal, state or local legislation or regulations under which we will operate our natural gas gathering, transmission and storage businesses may have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Any significant decrease in production of natural gas in our areas of operation could adversely affect our business and operating results and reduce our cash available to make distributions. Our business is dependent on the continued availability of natural gas production and reserves in our areas of operation. A sustained low - price environment for natural gas or regulatory limitations could adversely affect development of additional reserves and production that is accessible by our pipeline and storage assets and fresh water sources. Production from natural gas wells will naturally decline over time. The amount of natural gas reserves underlying these wells may also be less than anticipated, and the rate at which production from these reserves declines may be greater than anticipated. Additionally, producers may determine in the future that drilling activities in areas outside of our current areas of operations are strategically more attractive to them due to the price environment for natural gas or other reasons. A reduction in the natural gas volumes supplied by producers could result in reduced throughput on our systems and adversely impact our ability to grow our operations and increase quarterly cash distributions to our unitholders. Accordingly, to maintain or increase the contracted capacity or the volume of natural gas gathered, transported and stored on our systems and cash flows associated therewith, our customers must continually access additional reserves of natural gas. The primary factors affecting our ability to obtain non-dedicated sources of natural gas include the level of successful drilling activity near our systems and our ability to compete for volumes from successful new wells. While EQT has dedicated production from certain of its leased properties to us, we have no control over the level of drilling activity in our areas of operation, the amount of reserves associated with wells connected to our gathering systems or the rate at which production from a well declines. In addition, we have no control over EQT or other producers or their drilling or production decisions, which are affected by, among other things, the availability and cost of capital, prevailing and projected energy prices, demand for 24 Table of Contents hydrocarbons, levels of reserves, the producer's contractual obligations to us and other midstream companies, geological considerations, environmental or other governmental regulations, the availability of drilling permits, the availability of drilling rigs and crews, and other production and development costs. Fluctuations in energy prices can also greatly affect the development of new natural gas reserves. In general terms, the prices of natural gas, oil and other hydrocarbon products fluctuate in response to changes in supply and demand, market uncertainty and a variety of additional factors that are beyond our control. For example, the daily spot prices for NYMEX Henry Hub natural gas ranged from a high of $7.13 per MMBtu to a low of $2.44 per MMBtu from January 1, 2017 through December 31 , 2018. Factors affecting natural gas prices include worldwide economic conditions; weather conditions and seasonal trends; the levels of domestic production and consumer demand; new exploratory finds of natural gas; the availability of imported, and the ability to export, natural gas and LNG; the availability of transportation systems with adequate capacity; the volatility and uncertainty of regional basis differentials and premiums; the price and availability of alternative fuels; the effects of energy conservation measures; the nature and extent of governmental regulation and taxation; and the anticipated future prices of natural gas, oil, LNG and other commodities. Low natural gas prices, particularly in the Appalachian Basin, have had a negative impact on exploration, development and production activity and, if sustained, could lead to a material decrease in such activity. Sustained reductions in exploration or production activity in our areas of operation would lead to reduced utilization of our systems. Because of these factors, even if new natural gas reserves are known to exist in areas served by our assets, producers may choose not to develop those reserves. Moreover, EQT may not develop the acreage it has dedicated to us. If reductions in drilling activity result in our inability to maintain levels of contracted capacity and throughput, it could reduce our revenue and impair our ability to make quarterly cash distributions to our unitholders. We do not obtain independent evaluations of natural gas reserves connected to our systems. Accordingly, we do not have independent estimates of total reserves connected to our systems or the anticipated life of such reserves. If the total reserves or estimated life of the reserves connected to our systems are less than we anticipate, or the timeline for the development of reserves is longer than we anticipate, and we are unable to secure additional sources of natural gas, there could be a material adverse effect on our business, results of operations, financial condition, liquidity and ability to make quarterly cash distributions to our unitholders. If new supplies of natural gas are not obtained to replace the natural decline in volumes from existing supply basins in our area of operation, or if natural gas supplies are diverted to serve other markets, the overall volume of natural gas gathered, transported and stored on our systems would decline, which could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Additionally, see '' We depend on EQT for a substantial majority of our revenues and future growth. For example, our water service business is directly associated with EQT's well completion activities and water needs, which are partially driven by horizontal lateral lengths and the number of completion stages per well. Therefore, we are subject to the business risks of EQT, and any further decrease in EQT's drilling or completion activity could adversely affect our business and operating results. We have no control over EQT's business decisions and operations, and EQT is under no obligation to adopt a business strategy that favors us .'' The lack of diversification of our assets and geographic locations could adversely affect our ability to make distributions to our unitholders. We rely exclusively on revenues generated from our gathering, transmission and storage and water systems, which are primarily located in the Appalachian Basin in Pennsylvania, West Virginia and Ohio. Due to our lack of diversification in assets and geographic location, an adverse development in these businesses or our areas of operations, including adverse developments due to catastrophic events, weather, regulatory action and decreases in demand for natural gas, could have a more significant impact on our results of operations and distributable cash flow to our unitholders than if we maintained more diverse assets and locations. We may not be able to increase our customer throughput and resulting revenue due to competition and other factors, which could limit our ability to grow. Part of our growth strategy includes diversifying our customer base by identifying opportunities to offer services to parties other than EQT. For the years ended December 31, 2018 , 2017 and 2016, EQT accounted for approximately 80% , 88% and 96% , respectively, of our gathering revenues and approximately 54% , 54% and 51% , respectively, of our transmission and storage revenues. For the year ended December 31, 2018 and for the period from November 13, 2017 through December 31, 2017, EQT accounted for approximately 93% and 99% of our water service revenues, respectively. EQT accounted for approximately 74% , 74% and 75% of our total revenues for the years ended December 31, 2018 , 2017 and 2016 , respectively. Our ability to increase our customer-subscribed capacity and throughput and resulting revenue is subject to numerous factors beyond our control, including competition from third-party producers' existing contractual obligations to competitors and the 25 Table of Contents extent to which we have available capacity when shippers require it. To the extent that we lack available capacity on our systems for volumes, we may not be able to compete effectively with third-party systems for additional natural gas production in our areas of operation. We have historically provided gathering, transmission, storage and water services to parties other than EQT on only a limited basis and may not be able to attract material service opportunities. Our efforts to attract new customers may be adversely affected by our desire to provide services pursuant to long-term firm contracts. Our potential customers may prefer to obtain services under other forms of contractual arrangements under which we would be required to assume direct commodity exposure. In addition, we must continue to improve our reputation among our potential customer base for providing high quality service to successfully attract new customers . The regulatory approval process for the construction of new midstream assets is challenging, and recent decisions by regulatory and judicial authorities in pending proceedings could impact EQM's or the MVP Joint Venture's ability to obtain all approvals and authorizations necessary to complete certain projects on the projected time frame or at all or EQM's ability to achieve the expected investment return on the project. Certain of our internal growth projects may require regulatory approval from federal, state and local authorities prior to construction, including any extensions from or additions to its transmission and storage system. The approval process for storage and transportation projects has become increasingly challenging, due in part to state and local concerns related to exploration and production, transmission and gathering activities in new production areas, including the Marcellus, Utica and Upper Devonian Shales, and negative public perception regarding the oil and gas industry, including major pipeline projects like the MVP. Such authorization may not be granted or, if granted, such authorization may include burdensome or expensive conditions. In addition, any significant delays in the regulatory approval process for the MVP project could increase costs and negatively impact the scheduled in-service date of fourth quarter 2019, which in turn could adversely affect the ability for the MVP Joint Venture and its owners, including us, to achieve the expected investment return. The MVP project is subject to several challenges that must be resolved before the MVP project can be completed, as described in more detail in "Item 3. Legal Proceedings." Although the MVP Joint Venture is actively defending the relevant agency actions and judicial challenges to the project, and is in active dialogue with all of the affected agencies to resolve these issues and restore the affected permits, there is no guarantee as to how long the agency proceedings and judicial challenges will take to resolve, or whether the MVP Joint Venture will ultimately succeed in restoring the permits in their present form or within the MVP Joint Venture's targeted time frame for placing the project in service. This and other similar litigation could adversely affect our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. We are exposed to the credit risk of our counterparties in the ordinary course of our business. We are exposed to the risk of loss resulting from the nonpayment and/or nonperformance of our customers, suppliers, joint venture partners and other counterparties. We extend credit to our customers, including EQT as our largest customer, as a normal part of our business. While we have established credit policies, including assessing the creditworthiness of our customers as permitted by our FERC-approved natural gas tariffs, and requiring appropriate terms or credit support from them based on the results of such assessments, we may not have adequately assessed the creditworthiness of our existing or future customers. We cannot predict the extent to which the businesses of our counterparties , including EQT, would be impacted if commodity prices decline, commodity prices are depressed for a sustained period of time, or other conditions in the energy industry were to deteriorate, nor can we estimate the impact such conditions would have on the abilities of our counterparties to perform under their gathering, transmission and storage and water service agreements with us. The low commodity price environment has negatively impacted natural gas producers causing some producers in the industry significant economic stress including, in certain cases, to file for bankruptcy protection or to renegotiate contracts. To the extent one or more of our customers is in financial distress or commences bankruptcy proceedings, contracts with these customers may be subject to renegotiation or rejection under applicable provisions of the United States Bankruptcy Code. Any resulting nonpayment and/or nonperformance by our counterparties could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Increased competition from other companies that provide gathering, transmission and storage , and water services, or from alternative fuel sources, could have a negative impact on the demand for our services, which could adversely affect our financial results. Our ability to renew or replace existing contracts at rates sufficient to maintain current revenues and cash flows could be adversely affected by the activities of our competitors. Our systems compete primarily with other interstate and intrastate 26 Table of Contents pipelines and storage facilities in the gathering, transmission and storage of natural gas. Some of our competitors have greater financial resources and may now, or in the future, have access to greater supplies of natural gas or water than we do. Some of these competitors may expand or construct gathering systems , transmission and storage systems and water systems that would create additional competition for the services we provide to our customers. In addition, our customers may develop their own gathering, transmission or storage , or water services instead of using ours. Moreover, none of Equitrans Midstream, EQT or any of their respective affiliates is limited in its ability to compete with us. The policies of the FERC promoting competition in natural gas markets are having the effect of increasing the natural gas transmission and storage options for our traditional customer base. As a result, we could experience some "turnback" of firm capacity as existing agreements expire. If we are unable to remarket this capacity or can remarket it only at substantially discounted rates compared to previous contracts, we may have to bear the costs associated with the turned back capacity. Increased competition could reduce the volumes of natural gas transported or stored on our system or, in cases where we do not have long-term firm contracts, could force us to lower our transmission or storage rates. Increased competition could also adversely affect demand for EQM's water services. Further, natural gas as a fuel competes with other forms of energy available to end-users, including coal, liquid fuels and renewable and alternative energy. Increased demand for such forms of energy at the expense of natural gas could lead to a reduction in demand for natural gas gathering, transmission and storage , and water services. All of these competitive pressures could make it more difficult for us to retain our existing customers and/or attract new customers as we seek to expand our business, which could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. In addition, competition could intensify the negative impact of factors that decrease demand for natural gas in the markets served by our systems, such as adverse economic conditions, weather, higher fuel costs and taxes or other governmental or regulatory actions that directly or indirectly increase the cost or limit the use of natural gas. If third party pipelines and other facilities interconnected to our pipelines and facilities become unavailable to transport or process natural gas, our revenues and cash available to make distributions to our unitholders could be adversely affected. We depend on third - party pipelines and other facilities that provide receipt and delivery options to and from our transmission and storage system. For example, our transmission and storage system interconnects with the following interstate pipelines: Texas Eastern, Dominion Transmission, Columbia Gas Transmission, Tennessee Gas Pipeline Company, Rockies Express Pipeline LLC , National Fuel Gas Supply Corporation and ET Rover Pipeline, LLC , as well as multiple distribution companies. Similarly, our gathering systems have multiple delivery interconnects to multiple interstate pipelines. In the event that our access to such systems was impaired, the amount of natural gas that our gathering systems can gather and transport would be adversely affected, which could reduce revenues from our gathering activities. Because we do not own these third - party pipelines or facilities, their continuing operation is not within our control. If these or any other pipeline connections or facilities were to become unavailable for current or future volumes of natural gas due to repairs, damage to the facility, lack of capacity or any other reason, our ability to operate efficiently and continue shipping natural gas to end markets could be restricted. Any temporary or permanent interruption at any key pipeline interconnect or facility could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Certain of the services we provide on our transmission and storage system are subject to long-term, fixed-price "negotiated rate" contracts that are not subject to adjustment, even if our cost to perform such services exceeds the revenues received from such contracts, and, as a result, our costs could exceed our revenues received under such contracts. It is possible that costs to perform services under "negotiated rate" contracts will exceed the negotiated rates we have agreed to provide to our customers. If this occurs, it could decrease the cash flow realized by our systems and, therefore, the cash we have available for distribution to our unitholders. Under FERC policy, a regulated service provider and a customer may mutually agree to a "negotiated rate," and that contract must be filed with and accepted by the FERC. As of December 31, 2018, approximately 86% of the contracted firm transmission capacity on our system was subscribed under such "negotiated rate" contracts. Unless the parties to these "negotiated rate" contracts agree otherwise, the contracts generally may not be adjusted to account for increased costs that could be caused by inflation or other factors relating to the specific facilities being used to perform the services. We may not be able to renew or replace expiring contracts at favorable rates or on a long-term basis. Our primary exposure to market risk occurs at the time our existing contracts expire and are subject to renegotiation and renewal. Based on total projected contractual revenues, including projected contractual revenues from future capacity expected 27 Table of Contents from expansion projects that are not yet fully constructed for which EQM has executed firm contracts, our firm gathering contracts and firm transmission and storage contracts had weighted average remaining terms of approximately 11 years and 15 years, respectively, as of December 31, 2018 . The extension or replacement of existing contracts, including our contracts with EQT, depends on a number of factors beyond our control, including: • • • • • the level of existing and new competition to provide services to our markets; the macroeconomic factors affecting natural gas economics for our current and potential customers; the balance of supply and demand, on a short-term, seasonal and long-term basis, in our markets; the extent to which the customers in our markets are willing to contract on a long-term basis; and the effects of federal, state or local regulations on the contracting practices of our customers. Any failure to extend or replace a significant portion of our existing contracts, or extending or replacing them at unfavorable or lower rates, could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. If the tariffs governing the services we provide are successfully challenged, we could be required to reduce our tariff rates, which could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Rate payers, the FERC or other interested stakeholders, such as state regulatory agencies, may challenge our rates offered to individual customers or the terms and conditions of service included in our tariffs. We do not have an agreement in place that would prohibit customers, including EQT or its affiliates, from challenging our tariffs. If any challenge were successful, among other things, the rates that we charge on our systems could be reduced. Successful challenges could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. See "Our natural gas gathering, transmission and storage services are subject to extensive regulation by federal, state and local regulatory authorities. Changes or additional regulatory measures adopted by such authorities could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make distributions." If we do not complete expansion projects, our future growth may be limited. A significant component of our growth strategy is to continue to grow the cash distributions on our units by expanding our business. Our ability to grow depends, in part, upon our ability to complete expansion projects , including, without limitation, the MVP, MVP Southgate and Hammerhead projects, that result in an increase in the cash we generate. We may be unable to complete successful, accretive expansion projects for many reasons, including, but not limited to, the following: • • • • • • an inability to identify attractive expansion projects; an inability to obtain necessary rights-of-way, real-estate rights or permits or other government approvals, including approvals by regulatory agencies, whether as a result of further government shutdowns or otherwise; an inability to successfully integrate the infrastructure we build; an inability to raise financing for expansion projects on economically acceptable terms; incorrect assumptions about volumes, revenues and costs, including potential growth; or an inability to secure adequate customer commitments to use the newly expanded facilities. In addition, our ability to secure required permits and rights-of-way or otherwise proceed with construction of our expansion projects could encounter opposition from political activists, who may attempt to delay pipeline construction through protests and other means, as has recently occurred to the MVP. Expanding our business by constructing new midstream assets subjects us to risks. Organic and greenfield growth projects are a significant component of our growth strategy. The development and construction of pipelines and storage facilities involves numerous regulatory, environmental, political and legal uncertainties beyond our control and will require the expenditure of significant amounts of capital. The development and construction of pipeline infrastructure and storage facilities expose us to construction risks such as the failure to meet customer contractual 28 Table of Contents requirements, delays caused by landowners or advocacy groups opposed to the natural gas industry, environmental hazards, adverse weather conditions, the performance of third-party contractors, the lack of available skilled labor, equipment and materials and the inability to obtain necessary rights-of-way or approvals and permits from regulatory agencies on a timely basis or at all (and maintain such rights of way, approvals and permits once obtained). These types of projects may not be completed on schedule, at the budgeted cost or at all. Moreover, our revenues may not increase for some time after completion of a particular project. For instance, we will be required to pay construction costs generally as they are incurred but construction will typically occur over an extended period of time, and we will not receive revenues or material increases in revenues until the project is placed into service. Moreover, we may construct facilities to capture anticipated future growth in production and/or demand in a region in which such growth does not materialize. As a result, new facilities may not be able to attract enough throughput to achieve our expected investment return, which could adversely affect our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. We may face opposition to the development or operation of our pipelines and facilities from various groups. We may face opposition to the development or operation of our pipelines and facilities from environmental groups, landowners, local groups and other advocates. Such opposition could take many forms, including organized protests, attempts to block or sabotage our operations, intervention in regulatory or administrative proceedings involving our assets, or lawsuits or other actions designed to prevent, disrupt or delay the development or operation of our assets and business. For example, repairing our pipelines often involves securing consent from individual landowners to access their property; one or more landowners may resist our efforts to make needed repairs, which could lead to an interruption in the operation of the affected pipeline or other facility for a period of time that is significantly longer than would have otherwise been the case. In addition, acts of sabotage or eco-terrorism could cause significant damage or injury to people, property or the environment or lead to extended interruptions of our operations. Any such event that interrupts the revenues generated by our operations, or which causes us to make significant expenditures not covered by insurance, could reduce our cash available for paying distributions to our unitholders, including Equitrans Midstream, and, accordingly, adversely affect our financial condition and the market price of our securities. Recently, activists concerned about the potential effects of climate change have directed their attention towards sources of funding for fossil-fuel energy companies, which has resulted in certain financial institutions, funds and other sources of capital restricting or eliminating their investment in energy-related activities. Ultimately, this could make it more difficult to secure funding for exploration and production activities or energy infrastructure related projects, and consequently could both indirectly affect demand for our services and directly affect our ability to fund construction or other capital projects. Acquisitions we may make could reduce, rather than increase, our cash generated from operations on a per unit basis. If we make acquisitions that we believe will be accretive, these acquisitions may nevertheless result in a decrease in the cash generated from operations on a per unit basis. Any acquisition involves potential risks, including, among other things: • mistaken assumptions about volumes, revenues and costs, including synergies and potential growth; • • • • • an inability to secure adequate customer commitments to use the acquired systems or facilities; an inability to integrate successfully the assets or businesses we acquire; the assumption of unknown liabilities for which we are not indemnified or for which our indemnity is inadequate; the diversion of management's and employees' attention from other business concerns; and unforeseen difficulties operating in new geographic areas or business lines. If any acquisition fails to be accretive to our distributable cash flow per unit, it could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Review of our goodwill has resulted in and could result in future significant impairment charges. GAAP requires us to perform an assessment of goodwill at the reporting unit level for impairment at least annually and whenever events or changes in circumstance indicate that the fair value of a reporting unit is less than its carrying amount. We may perform either a qualitative or quantitative assessment of potential impairment. Our qualitative assessment of potential impairment may result in the determination that a quantitative impairment analysis is not necessary. Under this elective process, 29 Table of Contents we assess qualitative factors to determine whether the existence of events or circumstances leads us to determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If after assessing the totality of events or circumstances, we determine that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing a quantitative analysis is not required. However, if we conclude otherwise, then we perform a quantitative impairment analysis. If we choose not to perform a qualitative assessment, or if we choose to perform a qualitative assessment but are unable to qualitatively conclude that no impairment has occurred, then we will perform a quantitative evaluation. In the case of a quantitative assessment, we estimate the fair value of the reporting unit with which the goodwill is associated and compare it to the carrying value. If the estimated fair value of a reporting unit is less than its carrying value, an impairment charge is recognized for the excess of the reporting unit's carrying value over its fair value. Assessing the recoverability of goodwill requires significant judgments and estimates by management. Fair values of goodwill are primarily estimated using discounted cash flows based on forecasts of financial results that incorporate assumptions including, but not limited to, the discount rate, terminal value factor, peer groups, control premiums and earnings before interest, taxes, depreciation and amortization multiples. All of our goodwill relates to businesses that were acquired and valued by EQT's management in the Rice Merger. Following the third quarter of 2018 and prior to the Separation, we identified impairment indicators in the form of production curtailments announced by a primary customer of the two reporting units to which our goodwill is recorded that could reduce volumetric-based fee revenues of those reporting units. For the year ended December 31, 2018, we determined that the carrying value of one of those reporting units (the RMP PA Gas Gathering reporting unit, which comprises the Pennsylvania gathering assets acquired in the Rice Merger) was greater than its fair value. As a result, we recognized impairment of goodwill of $261.9 million . If the operations or projected operating results of these businesses decline significantly, we could incur additional goodwill impairment charges. Future impairment charges could be significant and could have a material adverse impact on our financial condition and results of operations for the period in which the impairment is recorded. As of December 31, 2018, we had approximately $1.1 billion of goodwill, which will be monitored for future impairment. Management will continue to monitor and evaluate the factors underlying the fair market value of acquired businesses over the course of the year to determine if any interim assessments are necessary and will take any additional impairment charges required. Failure to successfully combine and integrate the businesses of EQM and RMP may adversely affect the future results of the combined organization and our ability to achieve the intended benefits of the EQM-RMP Merger. The success of the EQM-RMP Merger depends, in part, on our ability to realize the anticipated benefits from combining the businesses of EQM and RMP, and integration of the parties gathering systems remains ongoing. To realize these anticipated benefits, the businesses must be successfully combined and integrated. If the combined organization is not able to achieve these objectives, or is not able to achieve these objectives on a timely basis, the anticipated benefits of the EQM- RMP Merger may not be realized fully or at all. In addition, the ongoing integration may result in additional and unforeseen expenses, which could reduce the anticipated benefits of the EQM-RMP Merger. There can be no assurance that our combination with RMP will deliver the strategic, financial and operational benefits anticipated by us. Our business may be negatively impacted if it is unable to effectively manage its expanded operations, which could have a material adverse effect on our ability to make quarterly cash distributions to our unitholders. If we are unable to obtain needed capital or financing on satisfactory terms to fund expansions of our asset base or acquisitions, our ability to make quarterly cash distributions may be diminished or our financial leverage could increase. We do not have any commitment with our general partner or Equitrans Midstream to provide any direct or indirect financial assistance to us. In order to expand our asset base and complete our announced expansion projects, including the MVP , MVP Southgate and Hammerhead projects, we will need to make significant expansion capital expenditures and acquisition capital expenditures. If we do not make sufficient or effective capital expenditures, we will be unable to expand our business operations and may be unable to maintain or raise the level of our quarterly cash distributions. In order to fund our expansion capital expenditures and acquisition capital expenditures, we will be required to use cash from our operations, incur borrowings or sell additional common units or other partner interests. Using cash from operations will reduce distributable cash flow to our common unitholders. Our ability to obtain bank financing or to access the capital markets for future equity or debt offerings may be limited by our financial condition at the time of any such financing or offering, the covenants in our debt agreements, general economic conditions and contingencies and uncertainties that are beyond our control. Furthermore, market demand for equity issued by master limited partnerships has been significantly lower in recent years than it has been historically, which may make it more challenging for us to finance our expansion capital expenditures and acquisition capital expenditures with the issuance of equity in the capital markets. Even if we are successful in obtaining funds for expansion and acquisition capital expenditures through equity or debt financings, the terms thereof could limit our ability to 30 Table of Contents pay distributions to our common unitholders. In addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing additional partner interests may result in significant common unitholder dilution and increase the aggregate amount of cash required to maintain the then- current distribution rates , which could materially decrease our ability to pay distributions at the then-current distribution rates. If funding is not available to us when needed, or is available only on unfavorable terms, we may be unable to execute our business plans, complete acquisitions or otherwise take advantage of business opportunities or respond to competitive pressures, any of which could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. There is no commitment from our general partner or Equitrans Midstream to provide any direct or indirect financial assistance to us. We are subject to numerous hazards and operational risks. Our business operations are subject to all of the inherent hazards and risks normally incidental to the gathering, transmission and storage of natural gas and performance of water services. These operating risks include, but are not limited to: • • • • • • • damage to pipelines, facilities, equipment , environmental controls and surrounding properties caused by hurricanes, earthquakes, tornadoes, abnormal amounts of rainfall, floods, fires, droughts, landslides and other natural disasters and acts of sabotage and terrorism; inadvertent damage from construction, vehicles, and farm and utility equipment; uncontrolled releases of natural gas and other hydrocarbons; leaks, migrations or losses of natural gas as a result of the malfunction of equipment or facilities and, with respect to storage assets, as a result of undefined boundaries, geologic anomalies, natural pressure migration and wellbore migration; ruptures, fires and explosions; pipeline freeze offs due to cold weather; and other hazards that could also result in personal injury and loss of life, pollution to the environment and suspension of operations. These risks could result in loss of human life, personal injuries, significant damage to property, environmental pollution, impairment of our operations, regulatory investigations and penalties and substantial losses to us. The location of certain segments of our systems in or near populated areas, including residential areas, commercial business centers and industrial sites, could increase the damages resulting from these risks. In spite of any precautions taken, an event such as those described above could cause considerable harm to people , property or the environment and could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Accidents or other operating risks could further result in loss of service available to our customers. Such circumstances, including those arising from maintenance and repair activities, could result in service interruptions on segments of our systems. Potential customer impacts arising from service interruptions on segments of our systems could include limitations on our ability to satisfy customer requirements, obligations to provide reservation charge credits to customers in times of constrained capacity, and solicitation of our existing customers by others for potential new projects that would compete directly with our existing services. Such circumstances could adversely impact our ability to meet contractual obligations and retain customers, with a resulting negative impact on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Negative public perception regarding us, the MVP, MVP Southgate, our other projects and/or the midstream industry could have an adverse effect on our operations. Negative public perception regarding us, the MVP, MVP Southgate, our other projects and/or the midstream industry resulting from, among other things, oil spills, the explosion of natural gas transmission and gathering lines, erosion and sedimentation issues, and general concerns raised by advocacy groups about hydraulic fracturing and pipeline projects has led to, and may in the future lead to, increased regulatory scrutiny, which may, in turn, lead to new local, state and federal safety and environmental laws, regulations, guidelines and enforcement interpretations. See "Item 3. Legal Proceedings." These actions have caused, and may continue to cause, operational delays or restrictions, increased construction and operating costs, penalties under construction contracts, additional regulatory burdens and increased risk of litigation. As discussed under " – The regulatory approval process for the construction of new midstream assets is challenging, and recent decisions by regulatory and judicial authorities in pending proceedings could impact EQM's or the MVP Joint Venture's ability to obtain all approvals and authorizations necessary to complete certain projects on the projected time frame or at all or 31 Table of Contents EQM's ability to achieve the expected investment return on the project ," there are several pending challenges to certain aspects of the MVP project that must be resolved before the MVP project can be completed. Moreover, governmental authorities exercise considerable discretion in the timing and scope of permit issuance and the public may engage in the permitting process, including through intervention in the courts. Negative public perception could cause the permits we and the MVP Joint Venture need to conduct our operations to be removed, withheld, delayed or burdened by requirements that restrict our ability to profitably conduct business. We do not insure against all potential losses and could be seriously harmed by unexpected liabilities. We are not fully insured against all risks inherent in our business, including environmental accidents that might occur. In addition, we do not maintain business interruption insurance of the types and in amounts necessary to cover all possible risks of loss, like project delays caused by governmental action or inaction. The occurrence of any operating risks not fully covered by insurance could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Equitrans Midstream currently maintains excess liability insurance that covers Equitrans Midstream and its affiliates, including our, legal and contractual liabilities arising out of bodily injury, personal injury or property damage, including resulting loss of use, to third parties. This excess liability insurance includes coverage for sudden and accidental pollution liability but excludes: release of pollutants subsequent to their disposal; release of substances arising from the combustion of fuels that result in acidic deposition; and testing, monitoring, clean-up, containment, treatment or removal of pollutants from property owned, occupied by, rented to, used by or in the care, custody or control of Equitrans Midstream and its affiliates, including us. Equitrans Midstream also maintains coverage for us and our affiliates, for physical damage to assets and resulting business interruption, including damage caused by terrorist acts. All of Equitrans Midstream's insurance is subject to deductibles or self-insured retentions . If a significant accident or event occurs for which Equitrans Midstream is not fully insured, it could adversely affect our operations and financial condition. Equitrans Midstream may not be able to maintain or obtain insurance for itself and its affiliates, of the types and in the amounts we desire at reasonable rates, and Equitrans Midstream may elect to self-insure a portion of EQM's asset portfolio. The insurance coverage Equitrans Midstream has obtained or may obtain may contain large deductibles or fail to cover certain hazards or cover all potential losses. In addition, for pre-Distribution losses, Equitrans Midstream will share insurance coverage with EQT. Equitrans Midstream will remain responsible for payment of any deductible or self-insured amounts under those insurance policies. To the extent we experience a pre-Distribution loss that would be covered under EQT's insurance policies, our ability to collect under those policies may be reduced to the extent EQT erodes the limits under those policies. Terrorist or cyber security attacks or threats thereof aimed at our pipelines or facilities or surrounding areas and new laws and regulations governing data privacy could adversely affect our business. Our business has become increasingly dependent upon digital technologies, including information systems, infrastructure and cloud applications, to operate our assets, and the maintenance of our financial and other records has long been dependent upon such technologies. The U.S. government has issued public warnings that indicate that energy assets might be specific targets of cyber security threats. Deliberate attacks on, or unintentional events affecting, our systems or infrastructure, the systems or infrastructure of third parties or the cloud could lead to corruption or loss of our proprietary data and potentially sensitive data, delays in delivery of natural gas and NGLs, difficulty in completing and settling transactions, challenges in maintaining our books and records, communication interruptions, environmental damage, personal injury, property damage and other operational disruptions, as well as damage to our reputation, financial condition and cash flows. Further, as cyber incidents continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyber incidents. In addition, new U.S. laws and regulations governing data privacy and the unauthorized disclosure of personal information may potentially elevate our compliance costs. Any failure by us to comply with these laws and regulations, including as a result of a cyber incident, could result in significant penalties and liability to us. Additionally, if we acquire a company that has violated or is not in compliance with applicable data protection laws, we may incur significant liabilities and penalties as a result. We are subject to stringent environmental laws and regulations that may expose us to significant costs and liabilities. Our operations are regulated extensively at the federal, state and local levels. Laws, regulations and other legal requirements have increased the cost to plan, design, install, operate and abandon gathering , transmission and water systems and pipelines. Environmental, health and safety legal requirements govern discharges of substances into the air, water and ground; the management and disposal of hazardous substances and wastes; the clean-up of contaminated sites; groundwater quality and availability; plant and wildlife protection; locations available for pipeline construction; environmental impact studies and assessments prior to permitting; restoration of properties after construction or operations are completed; pipeline safety 32 Table of Contents (including replacement requirements); and work practices related to employee health and safety. Compliance with the laws, regulations and other legal requirements applicable to our business, including delays in obtaining permits or other government approvals, may increase our costs of doing business, result in delays or restrictions in the performance of operations due to the need to obtain additional or more detailed permits or other governmental approvals or even cause us not to pursue a project. For example, the U.S. Fish and Wildlife Service continues to receive hundreds of petitions to consider listing of additional species as endangered or threatened and is being regularly sued or threatened with lawsuits to address these petitions. Some of these legal actions may result in the listing of species located in areas in which we operate. Such designations of previously unprotected species as being endangered or threatened, or the designation of previously unprotected areas as a critical habitat for such species, can result in increased costs, construction delays, restrictions in our operations or abandonment of projects. Listing of aquatic species could potentially affect water supplies or delay related infrastructure development. In addition, compliance with laws, regulations or other legal requirements could subject us to claims for personal injuries, property damage and other damages. Our failure to comply with the laws, regulations and other legal requirements applicable to our business, even if as a result of factors beyond our control, could result in the suspension or termination of our operations and subject us to administrative, civil and criminal penalties and damages. Laws, regulations and other legal requirements are constantly changing, and implementation of compliant processes in response to such changes could be costly and time consuming. For example, in October 2015, the EPA revised the NAAQS for ozone from 75 parts per billion for the current 8-hour primary and secondary ozone standards to 70 parts per billion for both standards. The EPA may designate the areas in which we operate as nonattainment areas. States that contain any areas designated as nonattainment areas will be required to develop implementation plans demonstrating how the areas will attain the applicable standard within a prescribed period of time. These plans may require the installation of additional equipment to control emissions. In addition, in May 2016, the EPA finalized rules that impose volatile organic compound emissions limits (and collaterally reduce methane emissions) on certain types of compressors and pneumatic pumps, as well as requiring the development and implementation of leak monitoring plans for compressor stations. The EPA finalized amendments to some requirements in these standards in March 2018 and September 2018, including rescission of certain requirements and revisions to other requirements such as fugitive emissions monitoring frequency . Compliance with these or other new regulations could, among other things, require installation of new emission controls on some of our equipment, result in longer permitting timelines, and significantly increase our capital expenditures and operating costs, which could adversely impact our business. In addition to periodic changes to air, water and waste laws, as well as recent EPA initiatives to impose climate change-based air regulations on industry, the U.S. Congress and various states have been evaluating climate-related legislation and other regulatory initiatives that would further restrict emissions of GHG , including methane (a primary component of natural gas) and carbon dioxide (a byproduct of burning natural gas). Several states are also pursuing similar measures to regulate emissions of GHGs from new and existing sources. If implemented, such GHG restrictions may result in additional compliance obligations with respect to, or taxes on the release, capture and use of GHGs that could have an adverse effect on our operations. There is a risk that we may incur costs and liabilities in connection with our operations due to historical industry operations and waste disposal practices, our handling of wastes and potential emissions and discharges related to our operations. Private parties, including the owners of the properties through which our gathering system or our transmission and storage system pass and facilities where our wastes are taken for reclamation or disposal, may have the right to pursue legal actions to require remediation of contamination or enforce compliance with environmental requirements as well as to seek damages for personal injury or property damage. In addition, changes in environmental laws occur frequently, and any such changes that result in more stringent and costly waste handling, storage, transport, disposal or remediation requirements could have a material adverse effect on our business, financial condition, results of operations, liquidity or ability to make quarterly cash distributions to our unitholders. We may not be able to recover all or any of these costs from insurance. Climate change and related legislation, regulatory initiatives and litigation could result in increased operating costs and reduced demand for the natural gas services we provide. Legislative and regulatory measures to address climate change and GHG emissions are in various phases of discussion or implementation. The EPA regulates GHG emissions from new and modified facilities that are potential major sources of criteria pollutants under the Clean Air Act's Prevention of Significant Deterioration and Title V programs and has adopted regulations that require, among other things, preconstruction and operating permits for certain large stationary sources and the monitoring and reporting of GHGs from certain onshore oil and natural gas production sources on an annual basis. In addition, the U.S. Congress, along with federal and state agencies, has considered measures to reduce the emissions of GHGs. Legislation or regulation that restricts carbon emissions could increase our cost of environmental compliance by requiring us to install new equipment to reduce emissions from larger facilities and/or, depending on any future legislation, purchase emission allowances. Climate change and GHG legislation or regulation could also delay or otherwise negatively affect efforts to obtain and maintain permits and other regulatory approvals for existing and new facilities, impose additional 33 Table of Contents monitoring and reporting requirements or adversely affect demand for the natural gas we gather, transport and store. Conversely, legislation or regulation that sets a price on or otherwise restricts carbon emissions could also benefit us by increasing demand for natural gas because the combustion of natural gas results in substantially fewer carbon emissions per Btu of heat generated than other fossil fuels such as coal. The effect on us of any new legislative or regulatory measures will depend on the particular provisions that are ultimately adopted. Significant portions of our pipeline systems have been in service for several decades. There could be unknown events or conditions or increased maintenance or repair expenses and downtime associated with our pipelines that could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make distributions. Significant portions of our transmission and storage system and FERC-regulated gathering system have been in service for several decades. The age and condition of these systems could result in increased maintenance or repair expenditures, and any downtime associated with increased maintenance and repair activities could materially reduce our revenue. Any significant increase in maintenance and repair expenditures or loss of revenue due to the age or condition of our systems could adversely affect our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. We may incur significant costs and liabilities as a result of increasingly stringent pipeline safety regulation, including pipeline integrity management program testing and related repairs. The DOT, acting through PHMSA , has adopted regulations requiring pipeline operators to develop integrity management programs for transmission pipelines located where a leak or rupture could harm HCAs, including high population areas, unless the operator effectively demonstrates by risk assessment that the pipeline could not affect the area. The regulations require operators, including us, to: • • perform ongoing assessments of pipeline integrity; identify and characterize applicable threats to pipeline segments that could impact a HCA; • maintain processes for data collection, integration and analysis; • • repair and remediate pipelines as necessary; and implement preventive and mitigating actions. Changes to pipeline safety laws and regulations that result in more stringent or costly safety standards could have a significant adverse effect on us and similarly situated midstream operators. For example, in April 2016, PHMSA published a notice of proposed rulemaking addressing several integrity management topics and proposing new requirements to address safety issues for natural gas transmission and gathering lines. The proposed rule would strengthen existing integrity management requirements, expand assessment and repair requirements to pipelines in areas with medium population densities and extend regulatory requirements to onshore gas gathering lines that are currently exempt. Further, in June 2016, then-President Obama signed the 2016 Pipeline Safety Act that extended PHMSA's statutory mandate under prior legislation through 2019. In addition, the 2016 Pipeline Safety Act empowered PHMSA to address imminent hazards by imposing emergency restrictions, prohibitions and safety measures on owners and operators of gas or hazardous liquid pipeline facilities without prior notice or an opportunity for a hearing and also required PHMSA to develop new safety standards for natural gas storage facilities by June 2018. Pursuant to those provisions of the 2016 Pipeline Safety Act, in October 2016 and December 2016, PHMSA issued two Interim Final Rules that expanded the agency's authority to impose emergency restrictions, prohibitions and safety measures and strengthened the rules related to underground natural gas storage facilities, including well integrity, wellbore tubing and casing integrity. The December 2016 Interim Final Rule, relating to underground gas storage facilities, went into effect in January 2017, with a compliance deadline in January 2018. PHMSA determined, however, that it will not issue enforcement citations to any operators for violations of provisions of the December 2016 Interim Final Rule that had previously been non-mandatory provisions of American Petroleum Institute Recommended Practices 1170 and 1171 until one year after PHMSA issues a final rule; however, no final rule has been issued. Additionally, in January 2017, PHMSA announced a new final rule regarding hazardous liquid pipelines, which increases the quality and frequency of tests that assess the condition of pipelines, requires operators to annually evaluate the existing protective measures in place for pipeline segments in HCAs, extends certain leak detection requirements for hazardous liquid pipelines not located in HCAs, and expands the list of conditions that require immediate repair. However, it is unclear when or if this rule will go into effect because, on January 20, 2017, the Trump Administration requested that all regulations that had been sent to the Office of the Federal Register, but were not yet published, be immediately withdrawn for further review. Accordingly, this rule has not become effective through publication in the Federal Register. We are monitoring and evaluating the effect of these and other emerging requirements on our operations. 34 Table of Contents States are generally preempted by federal law in the area of pipeline safety, but state agencies may qualify to assume responsibility for enforcing federal regulations over intrastate pipelines. They may also promulgate additive pipeline safety regulations provided that the state standards are at least as stringent as the federal standards. Although many of our natural gas facilities fall within a class that is not subject to integrity management requirements, we may incur significant costs and liabilities associated with repair, remediation, preventive or mitigation measures associated with our non-exempt transmission pipelines. The costs, if any, for repair, remediation, preventive or mitigating actions that may be determined to be necessary as a result of the testing program, as well as lost cash flows resulting from shutting down our pipelines during the pendency of such actions, could be material. Should we fail to comply with DOT regulations adopted under authority granted to PHMSA, we could be subject to penalties and fines. PHMSA has the authority to impose civil penalties for pipeline safety violations up to a maximum of approximately $200,000 per day for each violation and approximately $2 million for a related series of violations. This maximum penalty authority established by statute will continue to be adjusted periodically to account for inflation. In addition, we may be required to comply with new safety regulations and make additional maintenance capital expenditures in the future for similar regulatory compliance initiatives that are not reflected in our forecasted maintenance capital expenditures. The adoption of legislation relating to hydraulic fracturing and the enactment of new or increased severance taxes and impact fees on natural gas production could cause our current and potential customers to reduce the number of wells they drill in the Marcellus, Utica and Upper Devonian Shales or curtail production of existing wells. If reductions are significant for those or other reasons, the reductions would have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Our assets are primarily located in the Marcellus Shale fairway in southwestern Pennsylvania and northern West Virginia and the Utica Shale fairway in eastern Ohio , and a substantial majority of the production that we receive from customers is produced from wells completed using hydraulic fracturing. Hydraulic fracturing is an important and commonly used process in the completion of oil and gas wells, particularly in unconventional resource plays like the Marcellus, Utica and Upper Devonian Shales. Hydraulic fracturing is typically regulated by state oil and gas commissions and similar agencies, but several federal agencies have asserted regulatory authority over aspects of the process, including the EPA, which finalized effluent limit guidelines allowing zero discharge of waste water from shale gas extraction operations to a publicly owned treatment plant in 2016 in addition to existing limits on direct discharges. Additionally, in response to increased public concern regarding the alleged potential impacts of hydraulic fracturing, the EPA has asserted federal regulatory authority pursuant to the federal Safe Drinking Water Act (SDWA) over certain hydraulic fracturing activities involving the use of diesel fuels and published permitting guidance in February 2014 addressing the performance of such activities using diesel fuels. The federal Bureau of Land Management (BLM), has also asserted regulatory authority over aspects of the process, and issued a final rule in March 2015 that established more stringent standards for performing hydraulic fracturing on federal and Indian lands. The BLM rule was struck down by a federal court in Wyoming in June 2016, but was reinstated on appeal by the Tenth Circuit in September 2017. While this appeal was pending, BLM proposed a rulemaking in July 2017 to rescind these rules in their entirety. BLM published a final rule rescinding the 2015 rules in December 2017. However, other federal or state agencies may look to the BLM rule in developing new regulations that could apply to our operations. The U.S. Congress has from time to time considered the adoption of legislation to provide for federal regulation of hydraulic fracturing, while a growing number of states, including those in which we operate, have adopted, and other states are considering adopting, regulations that could impose more stringent disclosure and/or well construction requirements on hydraulic fracturing operations. Some states, such as Pennsylvania, have imposed fees on the drilling of new unconventional oil and gas wells. States could elect to prohibit hydraulic fracturing altogether, as was announced in December 2014 with regard to hydraulic fracturing activities in New York. Also, certain local governments have adopted, and additional local governments may further adopt, ordinances within their jurisdictions regulating the time, place and manner of drilling activities in general or hydraulic fracturing activities in particular. Further, several federal governmental agencies are conducting reviews and studies on the environmental aspects of hydraulic fracturing, including the EPA. For example, in December 2016, the EPA issued its final report on a study it had conducted over several years regarding the effects of hydraulic fracturing on drinking water sources. The final report, contrary to several previously published draft reports issued by the EPA, found instances in which impacts to drinking water may occur. However, the report also noted significant data gaps that prevented the EPA from determining the extent or severity of these impacts. The results of such reviews or studies could spur initiatives to further regulate hydraulic fracturing. State and federal regulatory agencies recently have focused on a possible connection between the hydraulic fracturing related activities and the increased occurrence of seismic activity. When caused by human activity, such events are called induced seismicity. In a few instances, operators of injection disposal wells in the vicinity of seismic events have been ordered to reduce injection volumes or suspend operations. Some state regulatory agencies, including those in Colorado, Ohio, Oklahoma and Texas, have modified their regulations to account for induced seismicity. While Pennsylvania is not one of the states where such 35 Table of Contents regulation has been enacted, regulatory agencies at all levels are continuing to study the possible linkage between oil and gas activity and induced seismicity. These developments could result in additional regulation and restrictions on the use of injection disposal wells and hydraulic fracturing. Such regulations and restrictions could cause delays and impose additional costs and restrictions on our customers. The adoption of new laws, regulations or ordinances at the federal, state or local levels imposing more stringent restrictions on hydraulic fracturing could make it more difficult for our customers to complete natural gas wells, increase our customers' costs of compliance and doing business, and otherwise adversely affect the hydraulic fracturing services they perform, which could negatively impact demand for our gathering, transmission and storage , or water services. Furthermore, the tax laws, rules and regulations that affect our customers are subject to change. For example, Pennsylvania's governor and legislature have continued to discuss the imposition of a state severance tax on the extraction of natural resources, including natural gas produced from the Marcellus, Utica and Upper Devonian Shale formations, either in replacement of or in addition to the existing state impact fee. A consensus on the characteristics, such as the effective tax rate, or enactment of a state severance tax has yet to be reached. Any such increase or change could adversely impact the earnings, cash flows and financial position of our customers and cause them to reduce their drilling in the areas in which we operate. Our exposure to direct commodity price risk may increase in the future. For the years ended December 31, 2018 and 2017, approximately 54% and 84%, respectively, of EQM's revenues were generated from firm reservation fees under long-term contracts. The decrease from 2017 to 2018 reflects the inclusion of RMP's gathering systems for a full year compared to the period from November 13, 2017 through December 31, 2017, as RMP's gathering systems were not supported by contracts with firm reservation fee components. Rather, all of RMP's gathering revenues were generated under long-term interruptible service contracts. As a result, following the EQM-RMP Merger, we have greater exposure to short- and medium-term declines in volumes of gas produced and gathered on our systems than we have historically. Although we intend to execute long-term firm contracts with new customers in the future, our efforts to obtain such contractual terms may not be successful. Our water service agreements are volumetric in nature and therefore may be more sensitive to fluctuations in commodity prices and downturns in production by our customers in the future. In addition, we may acquire or develop additional midstream assets in the future that do not provide services primarily based on capacity reservation charges or other fixed fee arrangements and therefore have a greater exposure to fluctuations in commodity price risk than our current operations. Future exposure to the volatility of natural gas prices, including regional basis differentials, as a result of our future contracts could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. We do not own all of the land on which our pipelines and facilities are located, which could disrupt our operations. We do not own all of the land on which our pipelines and facilities have been constructed, and we are therefore subject to the possibility of more onerous terms and/or increased costs to retain necessary land use if we do not have valid rights-of-way, if such rights-of-way lapse or terminate or if our facilities are not properly located within the boundaries of such rights-of-way. Although many of these rights are perpetual in nature, we occasionally obtain the rights to construct and operate our pipelines on land owned by third parties and governmental agencies for a specific period of time. If we were to be unsuccessful in negotiating or renegotiating rights-of-way, we might have to institute condemnation proceedings on our FERC-regulated assets or relocate our facilities for non-regulated assets. A loss of rights-of-way or a relocation could have a material adverse effect on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Additionally, even when we own an interest in the land on which our pipelines and facilities have been constructed, agreements with correlative rights owners may require us to relocate pipelines and facilities, shut in storage facilities to facilitate the development of the correlative rights owners' estate, or pay the correlative rights owners the lost value of their estate if they are not willing to accommodate development. Any significant and prolonged change in or stabilization of natural gas prices could have a negative impact on our natural gas storage business. Historically, natural gas prices have been seasonal and volatile, which has enhanced demand for and increased the value of our storage services. The natural gas storage business has benefited from significant short-term price fluctuations and seasonal price sensitivity, which impacts the level of demand for our services and the rates we are able to charge for such services. On a system-wide basis, natural gas is typically injected into storage between April and October when natural gas prices are generally lower and withdrawn during the winter months of November through March when natural gas prices are typically higher. However, the market for natural gas may not continue to experience short-term volatility and seasonal price sensitivity in the future at the levels previously seen. If price volatility and seasonality in the natural gas industry decrease, because of 36 Table of Contents increased production volumes and higher demand for natural gas during the injection season, the demand for our storage services and the prices that we will be able to charge for those services may decline. In addition to volatility and seasonality, an extended period of high natural gas prices would increase the cost of acquiring base gas and drilling new storage wells due to higher demand for drilling rigs and likely place upward pressure on the costs of associated storage expansion activities. An extended period of low natural gas prices could adversely impact storage values for some period of time until market conditions adjust. These commodity price impacts could have a negative impact on our business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. We have entered into joint ventures , and may in the future enter into additional or modify existing joint ventures, that might restrict our operational and corporate flexibility. In addition, these joint ventures are subject to many of the same operational risks to which we are subject. We have entered into joint ventures to construct the MVP and MVP Southgate projects and may in the future enter into additional joint venture arrangements with third parties. Joint venture arrangements may restrict our operational and corporate flexibility. Because we do not control all of the decisions of the MVP Joint Venture, it may be difficult or impossible for us to cause the joint venture to take actions that we believe would be in our or the joint venture's best interests. For example, we cannot unilaterally cause the distribution of cash by the MVP Joint Venture. Moreover, joint venture arrangements involve various risks and uncertainties, such as committing us to fund operating and/or capital expenditures, the timing and amount of which we may not control, and our joint venture partners may not satisfy their financial obligations to the joint venture. In addition, the operations of the MVP Joint Venture and any joint ventures we may enter into in the future are subject to many of the same operational risks to which we are subject to. Our significant indebtedness, and any future indebtedness, as well as restrictions under our debt agreements, could adversely affect our operating flexibility, business, financial condition, results of operations, liquidity and ability to make quarterly cash distributions to our unitholders. Our debt agreements contain various covenants and restrictive provisions that limit our ability to, among other things: • incur or guarantee additional debt; • make distributions on or redeem or repurchase units; • • • • incur or permit liens on assets; enter into certain types of transactions with affiliates; enter into certain mergers or acquisitions; and dispose of all or substantially all of our assets. In October 2018, we amended and restated our credit facility to increase the borrowing capacity from $ 1 billion to $ 3 billion and extend the term to October 2023. Our credit facility contains a covenant requiring us 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). Our ability to meet these covenants can be affected by events beyond our control and we cannot assure our unitholders that we will meet these covenants. In addition, our $ 3 billion credit facility contains events of default customary for such facilities, including the occurrence of a change of control. Furthermore, in June 2018, we issued senior unsecured notes in an aggregate principal amount of $2.5 billion, consisting of $1.1 billion in aggregate principal amount of its 4.75% senior notes due 2023, $850 million in aggregate principal amount of its 5.50% senior notes due 2028, and $550 million in aggregate principal amount of its 6.50% senior notes due 2048. The provisions of our debt agreements may affect our ability to obtain future financing and pursue attractive business opportunities and our flexibility in planning for, and reacting to, changes in business conditions. In addition, a failure to comply with the provisions of our debt agreements could result in an event of default, which could enable our creditors to, subject to the terms and conditions of the applicable agreement, declare any outstanding principal of that debt, together with accrued and unpaid interest, to be immediately due and payable. If the payment of our debt is accelerated, our assets may be insufficient to repay such debt in full, and our unitholders could experience a partial or total loss of their investment. Our credit facility also has cross default provisions that apply to any other indebtedness we may have with an aggregate principal amount in excess of $25 million. We may in the future incur additional debt. Our level of debt could have important consequences to us, including the following: 37 Table of Contents • • • • our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes, may be impaired or such financing may not be available on favorable terms; our funds available for operations, future business opportunities and distributions to unitholders will be reduced by that portion of our cash flow required to make interest payments on our debt; we may be more vulnerable to competitive pressures or a downturn in our business or the economy generally; and our flexibility in responding to changing business and economic conditions may be limited. Our ability to service our debt will depend upon, among other things, our future financial and operating performance, which will be affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond our control. If our operating results are not sufficient to service our current or future indebtedness, we will be forced to take actions such as reducing distributions, reducing or delaying our business activities, acquisitions, investments or capital expenditures, selling assets or seeking additional equity capital. We may not be able to effect any of these actions on satisfactory terms or at all. Our substantial indebtedness and the additional debt we will incur in the future for, among other things, working capital, capital expenditures, capital contributions to the MVP Joint Venture, acquisitions or operating activities may adversely affect our liquidity and therefore our ability to make quarterly cash distributions to our unitholders. In addition, our significant indebtedness may be viewed negatively by credit rating agencies, which could result in increased costs for us to access the capital markets. Any future downgrade of the debt issued by us or our subsidiaries could significantly increase our capital costs or adversely affect our ability to raise capital in the future. The credit and risk profile of Equitrans Midstream could adversely affect our credit ratings and risk profile, which could increase our borrowing costs or hinder our ability to raise capital. The credit and business risk profiles of our ultimate parent Equitrans Midstream may be factors considered in credit evaluations of us. This is because our general partner, which is controlled by Equitrans Midstream through Equitrans Midstream's ownership interest of our general partner, controls our business activities, including our cash distribution policy and growth strategy. Due to our relationship with Equitrans Midstream, our ability to access the capital markets, or the pricing or other terms of any capital markets transactions, may be adversely affected by any impairments to Equitrans Midstream's financial condition, including the degree of its financial leverage and its dependence on cash flows from our general partner to service its indebtedness, or adverse changes in its credit ratings. Any material limitations on our ability to access capital as a result of adverse changes at Equitrans Midstream could limit our ability to obtain future financing under favorable terms, or at all, or could result in increased financing costs in the future. Similarly, material adverse changes at Equitrans Midstream could negatively impact our unit price, limiting our ability to raise capital through equity issuances or debt financing, could negatively affect our ability to engage in, expand or pursue our business activities, and could also prevent us from engaging in certain transactions that might otherwise be considered beneficial to us. A downgrade of our credit ratings, which are determined by independent third parties, could impact our liquidity, our access to capital, and our costs of doing business. If any credit rating agency downgrades our credit ratings, our access to credit markets may be limited, our borrowing costs could increase, and we 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. Our credit ratings by Moody's Investors Service (Moody's), Standard & Poor's Ratings Service (S&P) and Fitch Ratings Service (Fitch) were Ba1, BBB- and BBB-, respectively, as of February 14, 2019. In order to be considered investment grade, we must be rated Baa3 or higher by Moody's, BBB- or higher by S&P and BBB- or higher by Fitch. Our non-investment grade credit rating by Moody's and any future downgrade of our S&P and/or Fitch credit ratings to non- investment grade may result in greater borrowing costs and collateral requirements than would be available to us if all our credit ratings were investment grade. Our ability to access capital markets could also be limited by economic, market or other disruptions. An increase in the level of our indebtedness in the future may result in a downgrade in the ratings that are assigned to our debt. See " The credit and risk profile of Equitrans Midstream could adversely affect our credit ratings and risk profile, which could increase our borrowing costs or hinder our ability to raise capital " in the above section. Credit rating agencies perform an independent analysis when assigning credit ratings. This analysis includes a number of criteria such as business composition, market and operational risks, as well as various financial tests. Credit rating agencies continue to review the criteria for industry sectors and various debt ratings and may make changes to those criteria from time to time. Credit ratings are subject to revision or withdrawal at any time by the ratings agencies. 38 Table of Contents Increases in interest rates could adversely impact demand for our storage capacity, our unit price, our ability to issue equity or incur debt for acquisitions or other purposes and our ability to make quarterly cash distributions at our intended levels. There is a financing cost for our customers to store natural gas in our storage facilities. That financing cost is impacted by the cost of capital or interest rates incurred by the customer in addition to the commodity cost of the natural gas in inventory. Absent other factors, a higher financing cost adversely impacts the economics of storing natural gas for future sale. As a result, a significant increase in interest rates could adversely affect the demand for our storage capacity independent of other market factors. In addition, interest rates on our current credit facility, future credit facilities and debt securities could be higher than current levels, causing our financing costs to increase. As with other yield-oriented securities, our unit price is impacted by the level of our cash distributions and implied distribution yield. The distribution yield is often used by investors to compare and rank yield-oriented securities for investment decision-making purposes. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our units, and a rising interest rate environment could have an adverse impact on our unit price, our ability to issue equity or incur debt for acquisitions or other purposes and our ability to make quarterly cash distributions at our intended levels. Risks Inherent in an Investment in Us Equitrans Midstream controls our general partner, which has sole responsibility for conducting our business and managing our operations. Potential conflicts of interest may arise among our general partner, its affiliates and us. Our general partner has limited its state law fiduciary duties to us and our unitholders, which may permit it to favor its own interests to the detriment of us and our unitholders. Additionally, the duties of our general partner's officers and directors may conflict with their duties as officers and/or directors of Equitrans Midstream. Equitrans Midstream’s only cash-generating assets are its partnership interests in us. Through its ownership and control of our general partner, Equitrans Midstream has the power to appoint all of the officers and directors of our general partner. Conflicts of interest will arise among Equitrans Midstream and our general partner, on the one hand, and us and our unitholders, on the other hand. In resolving these conflicts of interest, our general partner may favor its own interests and the interests of Equitrans Midstream over our interests and the interests of our unitholders. These conflicts include the following situations, among others: • • • • • • • • • Neither our partnership agreement nor any other agreement requires Equitrans Midstream to pursue a business strategy that favors us, and the directors and officers of Equitrans Midstream have a fiduciary duty to make these decisions in the best interests of Equitrans Midstream, which may be contrary to our interests. Equitrans Midstream may choose to shift the focus of its investment and growth to areas not served by our assets. Equitrans Midstream is not limited in its ability to compete with us and may offer business opportunities and/or sell midstream assets to third parties without first offering us the right to bid for them. Our general partner is allowed to take into account the interests of parties other than us, such as Equitrans Midstream, in resolving conflicts of interest, which has the effect of limiting its state law fiduciary duty to our unitholders. Our general partner determines whether or not we incur debt and that decision may affect our credit ratings. Our partnership agreement replaces the fiduciary duties that would otherwise be owed by our general partner with contractual standards governing its duties, limits our general partner's liabilities and restricts the remedies available to our unitholders for actions that, without such limitations, might constitute breaches of fiduciary duty under state law. Except in limited circumstances, our general partner has the power and authority to conduct our business without unitholder approval. Our general partner controls the enforcement of the obligations that it and its affiliates owe to us, including Equitrans Midstream's obligations under the ETRN Omnibus Agreement. Our partnership agreement gives our general partner broad discretion in establishing financial reserves for the proper conduct of our business. These reserves will affect the amount of cash available for distribution to our unitholders. Our general partner determines the amount and timing of asset purchases and sales, borrowings, issuances of additional partnership securities and the creation, reduction or increase of reserves, each of which can affect the amount of cash available for distribution to our unitholders. 39 Table of Contents • • • • • • • • Our general partner determines the amount and timing of any capital expenditures and, in accordance with the terms of our partnership agreement, whether a capital expenditure is classified as a maintenance capital expenditure, which reduces operating surplus, or an expansion or investment capital expenditure, which does not reduce operating surplus. These determinations can affect the amount of cash that is distributed to our unitholders. Our general partner determines which costs incurred by it and its affiliates are reimbursable by us. Our general partner may cause us to borrow funds in order to permit the payment of cash distributions. Our partnership agreement permits us to classify up to $30 million as operating surplus, even if it is generated from asset sales, non-working capital borrowings or other sources that would otherwise constitute capital surplus. Our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with any of these entities on our behalf. Our general partner intends to limit its liability regarding our contractual and other obligations. Our general partner may exercise its right to call and purchase all of our common units not owned by it and its affiliates if they own more than 80% of the common units. Our general partner decides whether to retain separate counsel, accountants or others to perform services for us. In addition, our general partner's officers and directors have duties to manage our business in a manner beneficial to us, our unitholders and the owner of our general partner that is controlled by Equitrans Midstream. However, five of our general partner's directors and all of its officers are also officers and/or directors of Equitrans Midstream and owe fiduciary duties to Equitrans Midstream. Consequently, these directors and officers may encounter situations in which their obligations to Equitrans Midstream, on the one hand, and us, on the other hand, are in conflict. The resolution of these conflicts may not always be in our best interest or that of our unitholders. Further, our general partner's officers, all of whom are also officers of Equitrans Midstream (and are compensated by Equitrans Midstream), will have responsibility for overseeing the allocation of their own time and time spent by administrative personnel on our behalf and on behalf of Equitrans Midstream. These officers face conflicts regarding these time allocations that may adversely affect our results of operations, cash flows and financial condition. Please read Item 13, "Certain Relationships and Related Transactions, and Director Independence" in this Annual Report on Form 10-K. Equitrans Midstream may compete with us, which could adversely affect our ability to grow and our results of operations and cash available for distribution. Our partnership agreement provides that our general partner will be restricted from engaging in any business activities other than acting as our general partner and those activities incidental to its ownership of interests in us. Affiliates of our general partner, including Equitrans Midstream and its other subsidiaries, are not prohibited from owning assets or engaging in businesses that compete directly or indirectly with us. Equitrans Midstream currently holds interests in entities that own a significant amount of natural gas midstream assets and may make investments in and purchases of entities that acquire, own and operate other natural gas midstream assets. Equitrans Midstream is under no obligation to make any acquisition opportunities available to us. Moreover, while Equitrans Midstream may offer us the opportunity to buy additional assets from it, it is under no contractual obligation to accept any offer we might make with respect to such opportunity. Pursuant to the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to our general partner or any of its affiliates, including its executive officers and directors and Equitrans Midstream. Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our general partner and result in less than favorable treatment of us and our common unitholders. Our general partner may require us to forgo certain transactions in order to avoid the risk of Equitrans Midstream incurring material tax-related liabilities or indemnification obligations under Equitrans Midstream's tax matters agreement with EQT. 40 Table of Contents In order for Equitrans Midstream to avoid incurring material tax-related liabilities or indemnification obligations under its tax matters agreement with EQT, entered into in connection with the Separation, our general partner may require us to forgo certain transactions that would otherwise be advantageous, for the two-year period following the Separation. In particular, our general partner may require us to continue to operate certain business operations, even if a sale or discontinuance of such business would otherwise be advantageous. Moreover, to preserve the tax-free treatment of the Separation, our general partner may require us to forgo certain transactions, including certain asset dispositions and other strategic transactions. Equitrans Midstream or EQT may fail to perform under various transaction agreements that were executed as part of the Separation, or Equitrans Midstream may fail to have necessary systems and services in place when certain of the transaction agreements expire. In connection with the Separation, Equitrans Midstream and EQT entered into a Separation and Distribution Agreement as well as various other agreements, including a transition services agreement. The transition services agreement provides for the performance of select services by each company for the benefit of the other, in each case for a limited period of time after the Separation. With respect to services to be performed by EQT for the benefit of us, we are relying on EQT to satisfy its performance obligations under these agreements. If EQT is unable or unwilling to satisfy its obligations under these agreements, including its indemnification obligations, our business, results of operations and financial condition could be materially and adversely affected. If Equitrans Midstream does not have in place its own systems and services, or if Equitrans Midstream does not have agreements with other providers of these services, once transaction agreements with EQT expire or terminate, we may not be able to operate our business effectively and our profitability may decline. Equitrans Midstream is in the process of creating its own, or engaging third parties to provide, systems and services to replace many of the systems and services that EQT provided to us. However, Equitrans Midstream may not be successful in implementing these systems and services, we may incur additional costs in connection with or following the implementation of these systems and services, and Equitrans Midstream may not be successful in transitioning data from EQT's systems to its own. For a description of these agreements with EQT, see "Item 13. Certain Relationships and Related Party Transactions and Director Independence." Our partnership agreement requires that we distribute all of our available cash, which could limit our ability to grow and make acquisitions. We expect that we will distribute all of our available cash to our unitholders and will rely primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures. As a result, to the extent we are unable to finance growth externally, our cash distribution policy will significantly impair our ability to grow. In addition, because we intend to distribute all of our available cash, our growth may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement, and we do not anticipate there being limitations in our credit facilities, on our ability to issue additional units, including units ranking senior to our common units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which in turn may impact the available cash that we have to distribute to our unitholders. The NYSE does not require a publicly traded partnership like us to comply with certain of its corporate governance requirements. Unlike most corporations, we are not required by NYSE rules to have, and we do not intend to have, a majority of independent directors on our general partner's board of directors or a compensation committee or a nominating and corporate governance committee. Additionally, any future issuance of additional common units or other securities, including to affiliates, will not be subject to the NYSE's shareholder approval rules. Accordingly, unitholders will not have the same protections afforded to certain corporations that are subject to all of the NYSE corporate governance requirements. If any of our unitholders are not eligible taxable holders, such unitholders will not be entitled to allocations of income or loss or distributions or voting rights on their common units and their common units will be subject to redemption. In order to avoid any material adverse effect on the maximum applicable rates that can be charged to customers by our subsidiaries on assets that are subject to rate regulation by the FERC or an analogous regulatory body, we have adopted certain requirements regarding those investors who may own our common units. Eligible taxable holders are defined in our partnership agreement and generally include any individual or entity (i) whose, or whose owners', U.S. federal income tax status (or lack of proof thereof) does not have or is not reasonably likely to have, as determined by our general partner, a material adverse effect on the rates that can be charged to customers with respect to assets that are subject to regulation by the FERC or similar 41 Table of Contents regulatory body; or (ii) as to whom our general partner cannot make the determination in clause (i) above, if our general partner determines that it is in our best interest to permit such individual or entity to own our partnership interests. If any of our unitholders fails to fit the requirements of an eligible taxable holder or fails to certify or has falsely certified that such holder is an eligible taxable holder, such unitholder will not receive allocations of income or loss or distributions or voting rights on their units and they run the risk of having their units redeemed by us at the market price calculated in accordance with our partnership agreement as of the date of redemption. The redemption price will be paid in cash or by delivery of a promissory note, as determined by our general partner. Our partnership agreement replaces our general partner's fiduciary duties to holders of our common units with contractual standards governing its duties. Our partnership agreement contains provisions that eliminate the fiduciary standards to which our general partner would otherwise be held by state fiduciary duty law and replace those duties with several different contractual standards. For example, our partnership agreement permits our general partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner, free of any duties to us and our unitholders other than the implied contractual covenant of good faith and fair dealing, which means that a court will enforce the reasonable expectations of the partners where the language in the partnership agreement does not provide for a clear course of action. This provision entitles our general partner to consider only the interests and factors that it desires and relieves it of any duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. Examples of decisions that our general partner may make in its individual capacity include: • • • • • how to allocate corporate opportunities among us and other affiliates; whether to exercise its limited call right; whether to seek approval of the resolution of a conflict of interest by the conflicts committee of the board of directors of our general partner; how to exercise its voting rights with respect to the units it owns; and whether or not to consent to any merger, consolidation or conversion of the partnership or amendment to our partnership agreement. By purchasing a common unit, a common unitholder agrees to become bound by the provisions in our partnership agreement, including the above provisions. Our partnership agreement restricts the remedies available to holders of our common units for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty. Our partnership agreement contains provisions that restrict the remedies available to unitholders for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, our partnership agreement provides that: • • • • whenever our general partner, the board of directors of our general partner or any committee thereof (including the conflicts committee) makes a determination or takes, or declines to take, any other action in their respective capacities, our general partner, the board of directors of our general partner and any committee thereof (including the conflicts committee), as applicable, is required to make such determination, or take or decline to take such other action, in good faith, meaning that it subjectively believed that the decision was in the best interests of our partnership, and, except as specifically provided by our partnership agreement, will not be subject to any other or different standard imposed by our partnership agreement, Delaware law, or any other law, rule or regulation, or at equity; our general partner will not have any liability to us or our unitholders for decisions made in its capacity as a general partner so long as such decisions are made in good faith; our general partner and its officers and directors will not be liable for monetary damages to us or our limited partners resulting from any act or omission unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that our general partner or its officers and directors, as the case may be, acted in bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that the conduct was criminal; and our general partner will not be in breach of its obligations under our partnership agreement (including any duties to us or our unitholders) if a transaction with an affiliate or the resolution of a conflict of interest is: 42 Table of Contents • • • • approved by the conflicts committee of the board of directors of our general partner, although our general partner is not obligated to seek such approval; approved by the vote of unitholders holding a majority of our outstanding common units, excluding any common units owned by our general partner and its affiliates; determined by the board of directors of our general partner to be on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or determined by the board of directors of our general partner to be fair and reasonable to us, taking into account the totality of the relationships among the parties involved, including other transactions that may be particularly favorable or advantageous to us. In connection with a situation involving a transaction with an affiliate or a conflict of interest, any determination by our general partner or the conflicts committee must be made in good faith. If an affiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the conflicts committee and the board of directors of our general partner determines that the resolution or course of action taken with respect to the affiliate transaction or conflict of interest satisfies either of the standards set forth in the third and fourth sub-bullets above, then it will be presumed that, in making its decision, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership challenging such determination, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. Reimbursements due to our general partner and its affiliates for services provided to us or on our behalf will reduce distributable cash flow to our common unitholders. The amount and timing of such reimbursements will be determined by our general partner. Prior to making any distribution to our common unitholders, we will reimburse our general partner and its affiliates, including Equitrans Midstream, for expenses they incur and payments they make on our behalf. Under our partnership agreement and the ETRN Omnibus Agreement, we will reimburse our general partner and its affiliates for certain expenses incurred on our behalf, including administrative costs, such as compensation expenses for those persons who provide services necessary to run our business, and insurance expenses. Our partnership agreement provides that our general partner will determine in good faith the expenses that are allocable to us. The reimbursement of expenses and payment of fees, if any, to our general partner and its affiliates will reduce the amount of available cash to pay cash distributions to our common unitholders. Our unitholders do not elect our general partner or vote on our general partner's directors. Unlike the holders of common stock in a corporation, our unitholders have only limited voting rights and, therefore, limited ability to influence management's decisions regarding our business. Unitholders will have no right on an annual or ongoing basis to elect our general partner or its board of directors. Rather, the board of directors of our general partner will be appointed by Equitrans Midstream. Furthermore, if our public unitholders are dissatisfied with the performance of our general partner, they will have limited ability to remove our general partner. As a result of these limitations, the price at which our common units will trade could be diminished because of the absence or reduction of a takeover premium in the trading price. Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units. Our unitholders' voting rights are restricted by a provision in our partnership agreement which provides that any units held by a person or group that owns 20% or more of any class of units then outstanding, other than our general partner, its affiliates, their transferees and persons who acquired such units with the prior approval of the board of directors of our general partner, cannot be voted on any matter. In addition, our partnership agreement contains provisions limiting the ability of our unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting our unitholders' ability to influence the manner or direction of our management. As a result, the price at which our common units will trade may be lower because of the absence or reduction of a takeover premium in the trading price. Our general partner may transfer its general partner interest, or the control of our general partner may be transferred, to a third party without unitholder consent. Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent of our unitholders. Furthermore, our partnership agreement does not restrict the ability of (i) EQGP to transfer all or a portion of its ownership interest in our general partner to a third party, or (ii) Equitrans Midstream to transfer all or a portion of its ownership interest in EQGP's general partner to a third party. The new owner of our general partner or EQGP's general partner, as the case may be, would then be in a position to replace the board of directors and officers 43 Table of Contents of our general partner with its own designees and thereby exert significant control over the decisions made by the board of directors and officers of our general partner. We may issue additional units without unitholder approval, which would dilute our unitholders' existing ownership interests. Our partnership agreement does not limit the number of additional limited partner interests, including limited partner interests that rank senior to our common units, that we may issue at any time without the approval of our unitholders. The issuance by us of additional common units or other equity securities of equal or senior rank will have the following effects: • • • • • our existing unitholders' proportionate ownership interest in us will decrease; the amount of distributable cash flow on each unit may decrease; the ratio of taxable income to distributions may increase; the relative voting strength of each previously outstanding unit may be diminished; and the market price of our common units may decline. Equitrans Midstream may sell units in the public or private markets, and such sales could have an adverse impact on the trading price of our common un its. As of February 14, 2019, Equitrans Midstream beneficially owned 37,245,455 of our common units, representing a 30.6% limited partner interest in us. Following the completion of the EQM IDR Transaction, we expect Equitrans Midstream to own 117,245,455 of our common units and 7,000,000 of our Class B units, representing a 59.9% limited partner interest in us. In addition, we have agreed to provide our general partner and its affiliates, including Equitrans Midstream, with certain registration rights. The sale of these units in the public or private markets could have an adverse impact on the price of our common units or on any trading market that may develop. Our general partner intends to limit its liability regarding our obligations. Our general partner intends to limit its liability under contractual arrangements so that the counterparties to such arrangements have recourse only against our assets, and not against our general partner or its assets. Our general partner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to our general partner. Our partnership agreement permits our general partner to limit its liability, even if we could have obtained more favorable terms without the limitation on liability. In addition, we are obligated to reimburse or indemnify our general partner to the extent that it incurs obligations on our behalf. Any such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to our unitholders. Our general partner has a call right that may require our unitholders to sell their common units at an undesirable time or price. If at any time our general partner and its affiliates own more than 80% of our outstanding common units, our general partner will have the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the remaining units held by unaffiliated persons at a price that is not less than the then-current market price of our common units. As a result, our unitholders may be required to sell their common units at an undesirable time or price and may not receive any return on their investment. Our common unitholders may also incur a tax liability upon a sale of their common units. As of February 14, 2019, affiliates of our general partner owned a 30.6% limited partner interest in us. Following the completion of the EQM IDR Transaction, we expect those affiliates to own 59.9% of our outstanding common units, which we expect to consist of 117,245,455 common units and 7,000,000 Class B units. Our unitholders' liability may not be limited if a court finds that unitholder action constitutes control of our business. A general partner of a partnership generally has unlimited liability for the obligations of the partnership, except for those contractual obligations of the partnership that are expressly made without recourse to the general partner. Our partnership is organized under Delaware law, and we conduct business in a number of other states. The limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not been clearly established in some of the other states in which we do business. A unitholder could be liable for any and all of our obligations as if that unitholder were a general partner if a court or government agency were to determine that: • we were conducting business in a state but had not complied with that particular state's partnership statute; or 44 Table of Contents • such unitholder's right to act with other unitholders to remove or replace our general partner, to approve some amendments to our partnership agreement or to take other actions under our partnership agreement constitutes "control" of our business. Furthermore, under Delaware law, a unitholder may be liable to us for the amount of a distribution for a period of three years from the date of the distribution under certain circumstances. Our general partner may mortgage, pledge or grant a security interest in all or substantially all of our assets without prior approval of our unitholders. Our general partner may mortgage, pledge or grant a security interest in all or substantially all of our assets without prior approval of our unitholders. If our general partner at any time were to decide to incur debt and secure its obligations or indebtedness by all or substantially all of our assets, and if our general partner were to be unable to satisfy such obligations or repay such indebtedness, the lenders could seek to foreclose on our assets. The lenders could also sell all or substantially all of our assets under such foreclosure or other realization upon those encumbrances without prior approval of our unitholders, which would adversely affect the price of our common units. Unitholders may have liability to repay distributions that were wrongfully distributed to them. Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of an impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Transferees of common units are liable both for the obligations of the transferor to make contributions to the partnership that were known to the transferee at the time of transfer and for those obligations that were unknown if the liabilities could have been determined from the partnership agreement. Neither liabilities to partners on account of their partnership interest nor liabilities that are non-recourse to the partnership are counted for purposes of determining whether a distribution is permitted. Tax Risks to Our Common Unitholders Our tax treatment depends on our status as a partnership for federal income tax purposes. If the IRS were to treat us as a corporation for federal income tax purposes, which would subject us to entity-level taxation, then our distributable cash flow to our unitholders would be substantially reduced. The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for federal income tax purposes. We have not requested, and do not currently plan to request, a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes. Despite the fact that we are a limited partnership under Delaware law, it is possible in certain circumstances for a partnership such as ours to be treated as a corporation for federal income tax purposes. A change in our business or a change in current law could cause us to be treated as a corporation for federal income tax purposes or otherwise subject us to taxation as an entity. If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate, which is currently 21.0%, and would likely pay state and local income tax at varying rates. Distributions to our unitholders would generally be taxed again as corporate dividends (to the extent of our current and accumulated earnings and profits), and no income, gains, losses, deductions or credits would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our distributable cash flow to our unitholders would be substantially reduced. Therefore, if we were treated as a corporation for federal income tax purposes there would be a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units. Our partnership agreement provides that, if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us. If we were subjected to a material amount of additional entity-level taxation by individual states or other taxing jurisdictions, it would reduce our distributable cash flow to our unitholders. Changes in current law may subject us to additional entity-level taxation by individual states or other taxing jurisdictions. Because of widespread budget deficits and other reasons, several states and other taxing jurisdictions are evaluating ways to subject partnerships to entity-level taxation through the imposition of income, franchise and other forms of taxation. Imposition 45 Table of Contents of such additional tax on us would reduce the distributable cash flow to our unitholders. Our partnership agreement provides that, if a law is enacted or existing law is modified or interpreted in a manner that subjects us to entity-level taxation, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us. The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis. The present federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. From time to time, members of the U.S. Congress propose and consider such substantive changes to the existing federal income tax laws that affect publicly traded partnerships. If successful, the proposals could eliminate the qualifying income exception to the treatment of all publicly traded partnerships as corporations upon which we rely for our treatment as a partnership for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will ultimately be enacted, but it is possible that a change in law could affect us and may, if enacted, be applied retroactively. Any such changes could negatively impact the value of an investment in our common units. Our unitholders are required to pay income taxes on their share of our taxable income even if they do not receive any cash distributions from us. A unitholder's share of our taxable income, and its relationship to any distributions we make, may be affected by a variety of factors, including our economic performance, transactions in which we engage or changes in law and may be substantially different from any estimate we make in connection with a unit offering. A unitholder's allocable share of our taxable income will be taxable to such unitholder, which may require the unitholder to pay federal income taxes and, in some cases, state and local income taxes, even if the unitholder receives cash distributions from us that are less than the actual tax liability that results from that income or no cash distributions at all. A unitholder's share of our taxable income, and its relationship to any distributions we make, may be affected by a variety of factors, including our economic performance, which may be affected by numerous business, economic, regulatory, legislative, competitive and political uncertainties beyond our control, and certain transactions in which we might engage. For example, we may engage in transactions that produce substantial taxable income allocations to some or all of our unitholders without a corresponding increase in cash distributions to our unitholders, such as a sale or exchange of assets, the proceeds of which are reinvested in our business or used to reduce our debt, or an actual or deemed satisfaction of our indebtedness for an amount less than the adjusted issue price of the debt. A unitholder's ratio of its share of taxable income to the cash received by it may also be affected by changes in law. For instance, under the recently enacted law known as the Tax Cuts and Jobs Act of 2017 (the Tax Reform Legislation), the net interest expense deductions of certain business entities, including us, are limited to 30% of such entity's "adjusted taxable income," which is generally taxable income with certain modifications. If the limit applies, a unitholder's taxable income allocations will be more (or its net loss allocations will be less) than would have been the case absent the limitation. From time to time, in connection with an offering of our common units, we may state an estimate of the ratio of federal taxable income to cash distributions that a purchaser of our common units in that offering may receive in a given period. These estimates depend in part on factors that are unique to the offering with respect to which the estimate is stated, so the expected ratio applicable to other common units will be different, and in many cases less favorable, than these estimates. Moreover, even in the case of common units purchased in the offering to which the estimate relates, the estimate may be incorrect, due to the uncertainties described above, challenges by the IRS to tax reporting positions which we adopt, or other factors. The actual ratio of taxable income to cash distributions could be higher or lower than expected, and any differences could be material and could materially affect the value of our common units. If the IRS contests the federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contest will reduce our distributable cash flow to our unitholders. We have not requested, and do not currently plan to request, a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes or any other tax matter affecting us. The IRS may adopt positions that differ from the conclusions of our counsel expressed in a prospectus or from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain some or all of our counsel's conclusions or the positions we take, and such positions may not ultimately be sustained. A court may not agree with some or all of our counsel's conclusions or the positions we take. Any contest with the IRS, and the outcome of any IRS contest, may have a materially adverse impact on the market for our common units and the price at which they trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders and our general partner because the costs will reduce our distributable cash flow. 46 Table of Contents If the IRS makes audit adjustments to our income tax returns for tax years beginning after 2017, it (and some states) may assess and collect any resulting taxes (including any applicable penalties and interest) directly from us, in which case we may require our unitholders and former unitholders to reimburse us for such taxes (including any applicable penalties or interest) or, if we are required to bear such payment, our cash available for distribution to our unitholders might be substantially reduced. Pursuant to the Bipartisan Budget Act of 2015, if the IRS makes audit adjustments to our income tax returns for tax years beginning after 2017, it (and some states) may assess and collect any resulting taxes (including any applicable interest and penalties) directly from us. We will generally have the ability to shift any such tax liability to our general partner and our unitholders in accordance with their interests in us during the year under audit, but there can be no assurance that we will be able to do so (or will choose to do so) under all circumstances, or that we will be able to (or choose to) effect corresponding shifts in state income or similar tax liability resulting from the IRS adjustment in states in which we do business in the year under audit or in the adjustment year. If we make payments of taxes, penalties and interest resulting from audit adjustments, we may require our unitholders and former unitholders to reimburse us for such taxes (including any applicable penalties or interest) or, if we are required to bear such payment, our cash available for distribution to our unitholders might be substantially reduced. Additionally, we may be required to allocate an adjustment disproportionately among our unitholders, causing the publicly traded units to have different capital accounts, unless the IRS issues further guidance. In the event the IRS makes an audit adjustment to our income tax returns and we do not or cannot shift the liability to our unitholders in accordance with their interests in us during the year under audit, we will generally have the ability to request that the IRS reduce the determined underpayment by reducing the suspended passive loss carryovers of our unitholders (without any compensation from us to such unitholders), to the extent such underpayment is attributable to a net decrease in passive activity losses allocable to certain partners. Such reduction, if approved by the IRS, will be binding on any affected unitholders. Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us. In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year. However, under the Tax Reform Legislation, for taxable years beginning after December 31, 2017, our deduction for "business interest" is limited to the sum of our business interest income and 30% of our "adjusted taxable income." For purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or business interest income, and in the case of taxable years beginning before January 1, 2022, any deduction allowable for depreciation, amortization, or depletion. Tax gain or loss on the disposition of our common units could be more or less than expected. If our unitholders sell their common units, our unitholders will recognize a gain or loss for federal income tax purposes equal to the difference between the amount realized and their tax basis in those common units. Because distributions in excess of our unitholders' allocable share of our net taxable income decrease their tax basis in their common units, the amount, if any, of such prior excess distributions with respect to the common units our unitholders sell will, in effect, become taxable income to our unitholders if they sell such common units at a price greater than their tax basis in those common units, even if the price our unitholders receive is less than their original cost. Furthermore, a substantial portion of the amount realized on any sale or other disposition of our unitholders' common units, whether or not representing gain, may be taxed as ordinary income due to potential recapture items, including depreciation recapture. In addition, because the amount realized includes our unitholders' share of our nonrecourse liabilities, if our unitholders sell their common units, our unitholders may incur a tax liability in excess of the amount of cash they receive from the sale. Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in adverse tax consequences to them. Investment in common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs), and non-U.S. persons raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Distributions to non-U.S. persons will be reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons will be required to file U.S. federal income tax returns and pay tax on their share of our taxable income. Under the Tax Reform Legislation, if a unitholder sells or otherwise disposes of a common unit, the transferee is required to withhold 10.0% of the amount realized by the transferor unless the transferor certifies that it is not a foreign person, and we are required to deduct and withhold from the transferee amounts that should have been withheld by the transferee but were not withheld. However, the Department of the Treasury and the IRS have determined that this withholding requirement should not 47 Table of Contents apply to any disposition of a publicly traded interest in a publicly traded partnership (such as us) until regulations or other guidance have been issued clarifying the application of this withholding requirement to dispositions of interests in publicly traded partnerships. Accordingly, while this new withholding requirement does not currently apply to interests in us, there can be no assurance that such requirement will not apply in the future. Tax-exempt entities and non-U.S. persons should consult a tax advisor before investing in our common units. We will treat each purchaser of common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of our common units. Because we cannot match transferors and transferees of common units and because of other reasons, we have adopted depreciation and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from our unitholders' sales of common units and could have a negative impact on the value of our common units or result in audit adjustments to our unitholders' tax returns. We prorate our items of income, gain, loss and deduction for U.S. federal income tax purposes between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders. We prorate our items of income, gain, loss and deduction for U.S. federal income tax purposes between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. Treasury Regulations allow a similar monthly convention, but such regulations do not specifically authorize all aspects of the proration method we have adopted. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders. We are authorized to revise our method of allocation between transferee and transferor unitholders, as well as among unitholders whose interests vary during a taxable year, to conform to a method permitted under future Treasury Regulations. A unitholder who disposes of units prior to the ex-dividend date immediately preceding the record date set for a cash distribution for that quarter will be allocated items of our income, gain, loss and deduction attributable to the month of disposition (and any prior month for which the holder held such units on the first day of such month) but will not be entitled to receive a cash distribution for that period. A unitholder whose common units are loaned to a "short seller" to cover a short sale of common units may be considered as having disposed of those common units. If so, the unitholder would no longer be treated for federal income tax purposes as a partner with respect to those common units during the period of the loan and may recognize gain or loss from the disposition. Because a unitholder whose common units are loaned to a "short seller" to cover a short sale of common units may be considered as having disposed of the loaned common units, the unitholder may no longer be treated for federal income tax purposes as a partner with respect to those common units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan to the short seller, any of our income, gain, loss or deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income. Our unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller are urged to consult a tax advisor to discuss whether it is advisable to modify any applicable brokerage account agreements to prohibit their brokers from loaning their common units. We have adopted certain valuation methodologies in determining a unitholder's allocations of income, gain, loss and deduction. The IRS may challenge these methodologies or the resulting allocations, and such a challenge could adversely affect the value of our common units. In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our assets. Although we may from time to time consult with professional appraisers regarding valuation matters, we make many fair market value estimates using a methodology based on the market value of our common units as a means to measure the fair market value of our assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction. A successful IRS challenge to these methods or allocations could adversely affect the timing or amount of taxable income or loss being allocated to our unitholders. It also could affect the amount of gain from our unitholders' sale of common units and 48 Table of Contents could have a negative impact on the value of the common units or result in audit adjustments to our unitholders' tax returns without the benefit of additional deductions. As a result of investing in our common units, our unitholders may become subject to state and local taxes and return filing requirements in jurisdictions where we operate or own or acquire properties. In addition to federal income taxes, our unitholders will likely be subject to other taxes, including state and local taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or own property now or in the future, even if they do not live in any of those jurisdictions. Our unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those requirements. We own property or conduct business in Pennsylvania, West Virginia and Ohio and will be expanding into Virginia with the MVP project and North Carolina with the MVP Southgate project, each of which currently imposes a personal income tax on individuals. Each of these states also imposes an income or gross receipts tax on corporations and other entities. As we make acquisitions or expand our business, we may own property or conduct business in additional states that impose a personal income tax. It is our unitholders' responsibility to file all U.S. federal, state and local tax returns. Compliance with and changes in tax laws could adversely affect our performance. We are subject to extensive tax laws and regulations, including federal, state and foreign income taxes and transactional taxes such as excise, sales/use, payroll, franchise and ad valorem taxes. New tax laws and regulations and changes in existing tax laws and regulations are continuously being enacted that could result in increased tax expenditures in the future. Many of these tax liabilities are subject to audits by the respective taxing authority. These audits may result in additional taxes as well as interest and penalties. See also Item 7A, "Quantitative and Qualitative Disclosures About Market Risk," for further discussion regarding EQM's exposure to market risks, which is incorporated herein by reference. Item 1B. Unresolved Staff Comments None. Item 2. Properties Equitrans Midstream leases its headquarters office in Pittsburgh, Pennsylvania and its corporate office in Canonsburg, Pennsylvania. Pursuant to the ETRN Omnibus Agreement, EQM pays a proportionate share of Equitrans Midstream's costs to lease the building. EQM's real property falls into two categories: (i) parcels that it owns in fee and (ii) parcels in which its interest derives from leases, easements, rights-of-way, permits or licenses from landowners or governmental authorities permitting the use of such land for EQM's operations. Certain lands on which EQM's pipelines and facilities are located are owned by EQM in fee title, and EQM believes that it has satisfactory title to these lands. The remainder of the lands on which EQM's pipelines and facilities are located are held by EQM pursuant to surface leases or easements between EQM, as lessee or grantee, and the respective fee owners of the lands, as lessors or grantors. EQM has held, leased or owned many of these lands for many years without any material challenge known to EQM relating to the title to the land upon which the assets are located, and EQM believes that it has satisfactory leasehold estates, easement interests or fee ownership to such lands. EQM believes that it has satisfactory title to all of its material leases, easements, rights-of-way, permits and licenses, and EQM has no knowledge of any material challenge to its title to such assets or their underlying fee title. There are, however, certain lands within EQM's storage pools as to which it may not currently have vested real property rights, some of which are subject to ongoing acquisition negotiations or condemnation proceedings. In accordance with EQM's FERC certificates, the geological formations within which its permitted storage facilities are located cannot be used by third parties in any way that would detrimentally affect its storage operations, and EQM has the power of eminent domain with respect to the acquisition of necessary real property rights to use such storage facilities. Certain property owners have initiated legal proceedings against EQM and its affiliates for trespass, inverse condemnation and other claims related to these matters, and there is no assurance that other property owners will not initiate similar legal proceedings against EQM and its affiliates prior to final resolution. See "Item 1. Business" for a discussion and map of EQM's operations. 49 Table of Contents Item 3. Legal Proceedings In the ordinary course of business, various legal and regulatory claims and proceedings are pending or threatened against EQM and its subsidiaries. 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 incurred. EQM establishes reserves whenever it believes it to be appropriate for pending matters. Furthermore, after consultation with counsel and considering available insurance, EQM believes that the ultimate outcome of any matter currently pending against EQM will not materially affect its business, financial condition, results of operations, liquidity or ability to make distributions to EQM unitholders . Environmental Proceedings Allegheny Valley Connector, Cambria County, Pennsylvania. Between September 2015 and February 2016, EQM, as the operator of the AVC facilities, which, at that time, were owned by EQT, received eight Notices of Violation (NOVs) from the Pennsylvania Department of Environmental Protection (PADEP). The NOVs alleged violations of the Pennsylvania Clean Streams Law in connection with inadvertent releases of sediment and bentonite to water that occurred while drilling for a pipeline replacement project in Cambria County, Pennsylvania. EQT and EQM immediately addressed the releases and fully cooperated with the PADEP. In October 2016, EQM acquired the AVC facilities from EQT, including any future obligations related to these releases. On November 1, 2018, EQM and the PADEP agreed to a Consent Order and Agreement that requires ongoing monitoring and payment of a civil penalty of $163,000. The civil penalty has been paid, and documents resolving this matter have been signed. Consent Orders, Beta Pipeline Project, Greene County, PA, and Barracuda Pipeline Project, Washington County, PA . The PADEP issued multiple NOVs to EQM related to the Beta Pipeline Project for construction, sediment and erosion control issues and failure to implement required corrective actions during the period of November 2017 to April 2018. The PADEP also issued multiple NOVs to EQM related to a sediment slip in mid-2018 on the Barracuda Pipeline Project that impacted a surface water stream. EQM is working to bring this project into compliance and has reached a tentative settlement with the PADEP within the amount reserved. Administrative Order, Swarts Storage Field, Greene County, PA . On December 26, 2018, EQM received an administrative order from the PADEP alleging non- compliance with certain regulations and failure to submit required information regarding encroaching mining operations in the storage field and authorizing the PADEP to shut down the storage field. EQM believes that it has substantially complied with the regulations, has complied with the PADEP information requests, and objects to the factual foundations of the administrative order. On January 10, 2019, the PADEP issued a letter suspending the portion of the administrative order that purported to authorize the PADEP to shut down the storage field. The administrative order does not contain a penalty assessment; however, resolution of the matter may include imposition of operational constraints. On January 25, 2019, EQM filed an administrative appeal on the PADEP's order to preserve its rights in any future proceedings. No reserve has been established for this matter. Consent Order, Legacy Ohio Pipeline - Multiple Locations in Ohio. The Ohio Environmental Protection Agency (OEPA) has issued NOVs to EQM that encompass fill violations and/or storm water (sedimentation) violations incurred during the ownership of the Legacy Ohio pipeline by EQM's predecessor entities. The NOVs allege violations related to state storm water permits and state and federal clean water laws. EQM addressed the violations with agency oversight and cooperated with the OEPA to proactively address future corrective actions. EQM received a draft consent order in January 2019. Settlement discussions are ongoing. EQM believes it has reserved an amount sufficient to cover a settlement and expects that amount to be sufficient for any penalties associated with the Legacy Ohio pipeline. EQM is working to bring this project into compliance. MVP Project Challenges The MVP Joint Venture is currently defending certain agency actions and judicial challenges to the MVP that must be resolved favorably before the project can be completed, including the following: • In February 2018, the Sierra Club filed a lawsuit, Sierra Club, et al. v. U.S. Army Corps of Engineers, et al. , consolidated under Case No. 18-1173, in the United States Fourth Circuit Court of Appeals (Fourth Circuit) against the U.S. Army Corps of Engineers (the U.S. Army Corps) challenging the verification by the Huntington District of the U.S. Army Corps that Nationwide Permit 12, which generally authorizes under Section 404 of the Clean Water Act discharges of dredge or fill material into waters of the United States and the construction of pipelines across such waters, could be utilized in the Huntington District (which covers all but the northernmost area of West Virginia) for the MVP project. The crux of Sierra Club's position was that the MVP Joint Venture, pursuant to its FERC license, planned to use a certain methodology (dry open cut creek crossing methodology) to construct the pipeline across streams in West Virginia that would take considerably longer than the 72 hours allowed for such activities pursuant to 50 Table of Contents • • • the terms of West Virginia's Clean Water Act Section 401 certification for Nationwide Permit 12. A three-judge panel of the Fourth Circuit agreed with the Sierra Club and on October 2, 2018, issued a preliminary order stopping the construction in West Virginia of that portion of the pipeline that is subject to Nationwide Permit 12. Following the issuance of the court's preliminary order, the U.S. Army Corps' Pittsburgh District (which had also verified use of Nationwide Permit 12 by MVP in the northern corner of West Virginia) suspended its verification that allowed the MVP Joint Venture to use Nationwide Permit 12 for stream and wetlands crossings in northern West Virginia. On November 27, 2018, the Fourth Circuit panel issued its final decision vacating the Huntington District's verification of the use of Nationwide Permit 12 in West Virginia. As a consequence, unless and until West Virginia revises its Section 401 certification for Nationwide Permit 12 (an administrative process presently underway as described below) and the U.S. Army Corps Huntington and Pittsburgh Districts re-verify the MVP Joint Venture's use of Nationwide Permit 12, or the MVP Joint Venture secures an individual Section 404 permit with the concurrence of both Districts, the MVP Joint Venture cannot perform any construction activities in any streams and wetlands in West Virginia. The administrative proceeding described below is addressing the issues raised by the Court. On April 13, 2017, the West Virginia Department of Environmental Protection (WVDEP) issued a 401 Water Quality Certification for the U.S. Army Corps Nationwide Permits. In August 2018, the WVDEP initiated an administrative process to revise this certification and requested public comment to, among other things, specifically revise the 72-hour limit for stream crossings noted as problematic by the Fourth Circuit as well as other conditions. The WVDEP has issued a new notice and comment period for further modifications of the 401 certification. This notice and comment period will end on March 4, 2019. The full administrative process requires notice and opportunity for public comment, response to public comment, and adherence to the state's administrative procedures legislation. The WVDEP is also required to obtain the EPA's agreement to the modified 401 certification. Assuming that the WVDEP's administrative process results in the clarification or elimination of any problematic conditions, and the EPA's agreement is secured, the MVP Joint Venture anticipates that it will once again secure from the U.S. Army Corps Districts within West Virginia verification that its activities, including stream crossings, may proceed under Nationwide Permit 12 as re-certified by the WVDEP. The MVP Joint Venture expects that reverification to occur within the first half of 2019. However, the MVP Joint Venture cannot guarantee that either the WVDEP, the EPA or the U.S. Army Corps Districts will act promptly or be deemed to have acted properly if challenged, in which case re-verification may be delayed past the first half of 2019. In June 2018, the Sierra Club filed a second petition in the Fourth Circuit against the U.S. Army Corps, seeking review and a stay of the U.S. Army Corps' Norfolk District decision to verify the MVP Joint Venture's use of Nationwide Permit 12 for stream crossings in Virginia. Sierra Club, et al. v. U.S. Army U.S. Army Corps of Engineers, et al. , Case No. 18-1713. The Fourth Circuit denied the Sierra Club's request for a stay on August 28, 2018. On October 5, 2018, the U.S. Army Corps' Norfolk District suspended its verification under Nationwide Permit 12 for stream crossings in Virginia pending the resolution of the West Virginia proceedings outlined above. On December 10, 2018, the U.S. Army Corps filed a motion to place the case in abeyance which the court granted on January 9, 2019. Until the U.S. Army Corps lifts its suspension, the MVP Joint Venture cannot perform any construction activities in any streams and wetlands in Virginia. In a different Fourth Circuit appeal filed in December 2017, the Sierra Club challenged a Bureau of Land Management (BLM) decision to grant a right-of- way to the MVP Joint Venture and a U.S. Forest Service (USFS) decision to amend its management plan to accommodate MVP, both of which affect the MVP's 3.6-mile segment in the Jefferson National Forest in Virginia. Sierra Club, et al. v. U.S. Forest Service, et al. , consolidated under Case No. 17- 2399. On July 27, 2018, agreeing in part with the Sierra Club, the Fourth Circuit vacated the BLM and USFS decisions, finding fault with the USFS' analysis of erosion and sedimentation effects and the BLM's analysis of the practicality of alternate routes. On August 3, 2018, citing the court's vacatur and remand, the FERC issued a stop work order for the entire pipeline pending the agency actions on remand. The FERC modified its stop work order on August 29, 2018 to allow work to continue on all but approximately 25 miles of the project. The MVP Joint Venture has resumed construction of those portions of the pipeline. On October 10, 2018, the Fourth Circuit granted a petition for rehearing filed by the MVP Joint Venture for the limited purpose of clarifying that the July 27, 2018, order did not vacate the portion of the BLM's Record of Decision authorizing a right-of-way and temporary use permit for MVP to cross the Weston and Gauley Bridge Turnpike Trail in Braxton County, West Virginia. On October 15, 2018, the MVP Joint Venture filed with the FERC a request to further modify the August 3, 2018 stop work order to allow the MVP Joint Venture to complete bore and install the pipeline under the Weston and Gauley Bridge Turnpike Trail. On October 24, 2018, the FERC granted the MVP Joint Venture's request to further modify the stop work order and authorize construction. The MVP Joint Venture has resumed construction of those portions of the pipeline. However, work on the 3.6-mile segment in the Jefferson National Forest must await a revised authorization, which the MVP Joint Venture is working to obtain. 51 Table of Contents • • • • Multiple parties have sought judicial review of the FERC's order issuing a certificate of convenience and necessity to the MVP Joint Venture and/or the exercise by the MVP Joint Venture of eminent domain authority. There are multiple consolidated petitions before the Court of Appeals for the District of Columbia Circuit seeking direct review of the FERC order under the Natural Gas Act in Appalachian Voices, et al. v. FERC, et al ., consolidated under Case No. 17-1271. Those petitioners requested a stay of the FERC's order pending the resolution of the petitions, which the FERC and the MVP Joint Venture opposed. The Court of Appeals denied the request for a stay on August 30, 2018. Oral argument on the merits of the petitions for review was held on January 28, 2019. Another group of parties filed a complaint in the U.S. District Court for the District of Columbia asserting that the FERC's order issuing certificates is unlawful on constitutional and other grounds in Bold Alliance, et al. v. FERC, et al. , Case No. 1:17-cv-01822-RJL. The district court plaintiffs seek declaratory relief as well as an injunction preventing the MVP Joint Venture from developing its project or exercising eminent domain authority. In December 2017 and January 2018, the FERC and the MVP Joint Venture, respectively, moved to dismiss the petitions for lack of subject matter jurisdiction. The court granted the motion and dismissed this complaint on September 28, 2018. On October 26, 2018, plaintiffs appealed to the U.S. Court of Appeals for the District of Columbia in Bold Alliance, et al. v. FERC, et al. , Case No. 18-5322. On December 3, 2018, the FERC, as appellee, filed a joint motion with the appellants to hold Case No. 18-5322 in abeyance pending completion of the ongoing appeals of the final agency orders related to the MVP certificate in consolidated Case No. 17-1271. If one or more of these challenges were successful, it could result in the MVP Joint Venture's certificate of convenience and necessity being vacated and/or additional proceedings before the FERC, the outcome of which EQM cannot predict. Several landowners have challenged the constitutionality of the eminent domain provisions of the Natural Gas Act generally and as applied to the MVP Joint Venture specifically. The U.S. District Court for the Western District of Virginia, in Orus Ashby Berkley, et al. v. Mountain Valley Pipeline, LLC, et al. , Case No. 7:17-cv-00357-EKD, dismissed the challenge for lack of subject matter jurisdiction in January 2018. The Fourth Circuit affirmed this judgment on appeal in July 2018 in Orus Ashby Berkley, et al. v. Mountain Valley Pipeline, LLC, et al. , Case No. 18-1042. In October 2018, the plaintiffs petitioned the U.S. Supreme Court for a writ of certiorari with respect to these jurisdictional rulings in Orus Ashby Berkley, et al. v. FERC, et al. , Case No. 18-561. On January 22, 2019, the U.S. Supreme Court denied the writ of certiorari. Several landowners have filed challenges in various U.S. District Courts to the condemnation proceedings by which the MVP Joint Venture obtained access to their property. In each case, the district court found that the MVP Joint Venture was entitled to immediate possession of the easements, and the landowners appealed to the Fourth Circuit. The Fourth Circuit has consolidated these cases in Mountain Valley Pipeline, LLC v. 6.56 Acres of Land, et al. , consolidated under Case No. 18-1159, and held oral argument in September 2018. On February 5, 2019, the Fourth Circuit Court of Appeals issued an opinion affirming the decisions of the U.S. District Courts granting the MVP Joint Venture immediate access for construction of the pipeline. In August 2017, the Greenbrier River Watershed Association appealed the MVP Joint Venture's Natural Stream Preservation Act Permit obtained from the West Virginia Environmental Quality Board (WVEQB) for the Greenbrier River crossing. Petitioners alleged that the issuance of the permit failed to comply with West Virginia's Water Quality Standards for turbidity and sedimentation. WVEQB dismissed the appeal in June 2018. In July 2018, the Greenbrier River Watershed Association appealed the decision to the Circuit Court of Summers County, asking the court to remand the permit with instructions to impose state-designated construction windows and pre- and post-construction monitoring requirements as well as a reversal of the WVEQB's decision that the permit was lawful. On September 18, 2018, the Circuit Court granted a stay. A hearing on the merits was held on October 23, 2018. The court has not yet issued a decision. In the event of an adverse decision, the MVP Joint Venture would appeal or work with the WVDEP to attempt to resolve the issues identified by the court. Other Proceedings that May Affect the MVP Project • • On December 13, 2018, in Cowpasture River Preservation Association, et al. v. U.S. Forest Service, et al. , Case No. 18-1144, an unrelated case involving the Atlantic Coast Pipeline, the Fourth Circuit held that the Forest Service, which is part of the Department of Agriculture, lacked the authority to grant rights-of-way for oil and gas pipelines to cross the Appalachian Trail. Although the MVP Joint Venture obtained its grant to cross the Appalachian Trail from the BLM, a part of the Department of Interior, the rationale of the Fourth Circuit's opinion could apply to the BLM as well. The MVP Joint Venture anticipates that the Forest Service will request rehearing or en banc review of the Fourth Circuit's decision. On January 7, 2019, the MVP Joint Venture received a letter from the U.S. Attorney's Office for the Western District of Virginia stating that it and the EPA are investigating potential criminal and/or civil violations of the Clean Water Act 52 Table of Contents and other federal statutes as they relate to the construction of the MVP. The January 7, 2019 letter requests the MVP Joint Venture and its members, contractors, suppliers and other entities involved in the construction of the MVP to preserve documents related to the MVP generated from September 1, 2018 to the present. In a telephone call on February 4, 2019, the U.S. Attorney's Office confirmed that it has opened a criminal investigation. On February 11, 2019, the MVP Joint Venture received a grand jury subpoena from the U.S. Attorney's Office for the Western District of Virginia requesting certain documents related to the MVP from August 1, 2018 to the present. The MVP Joint Venture is complying with the letter and subpoena but cannot predict whether any action will ultimately be brought by the U.S. Attorney's Office or what the outcome of such an action would be. • On December 7, 2018, the Virginia Department of Environmental Quality and the State Water Control Board filed suit against the MVP Joint Venture in the Circuit Court of Henrico County, captioned Paylor, et al. v. Mountain Valley Pipeline, LLC , Case No. CL18-4874-00, alleging violations of Virginia's State Water Control Law, Water Resources and Wetlands Protection Program, and Water Protection Permit Program Regulations at sites in Craig, Franklin, Giles, Montgomery and Roanoke Counties, Virginia. The MVP Joint Venture answered the suit on January 11, 2019, stating that it does not admit and will contest the allegations. The MVP Joint Venture has initiated settlement negotiations to resolve this matter. The MVP Joint Venture anticipates that a resolution could result in penalties and injunctive relief designed to assure compliance with relevant environmental laws and regulations. Shortly after the filing of this suit, the Virginia State Water Control Board (VSWCB) voted to reconsider/schedule a hearing to revoke MVP's Clean Water Act Section 401 certification. The MVP Joint Venture was informed that the VSWCB has provided public notice of a special VSWCB meeting to be held on March 1, 2019 to discuss the MVP's Clean Water Act Section 401 certification. MVP will vigorously oppose any action by the VSWCB which would result in revocation of its authorizations to continue project activities in Virginia. Item 4. Mine Safety Disclosures Not applicable. PART II Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities EQM's common units are listed on the NYSE under the symbol "EQM." As of December 31, 2018 , EQM had 1,443,015 general partner units for which there is no established public trading market. The general partner units are owned indirectly by Equitrans Midstream. See Note 8 to the consolidated financial statements included in Item 8, "Financial Statements and Supplementary Data," of this Form 10-K for information on the significant provisions of EQM's partnership agreement that relate to distributions of available cash. As of January 31, 2019, there were 63 unitholders of record of EQM common units. Recent Sales of Unregistered Securities None. Market Repurchases None.

Management's Discussion and Analysis of Financial Condition and Results of Operations The following discussion and analysis of financial condition and results of operations should be read in conjunction with the consolidated financial statements, and the notes thereto, included in Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K. Executive Overview EQM reported net income attributable to EQM of $668.0 million in 2018 compared with $609.6 million in 2017 . The increase resulted primarily from higher gathering, water and transmission revenues, which were driven primarily by the EQM-RMP Merger and the Drop-Down Transaction, which supported production development in the Marcellus and Utica Shales, and higher equity income, partly offset by an impairment charge to goodwill, higher operating expenses and net interest expense. EQM reported net income of $609.6 million in 2017 compared with $538.0 million in 2016 . The increase resulted primarily from higher gathering and transmission revenues, which were mainly driven by affiliate and third party production development in the Marcellus Shale, and lower income taxes, partly offset by higher operating expenses and net interest expense and lower other income. EQM declared a cash distribution to its unitholders of $1.13 per unit on January 16, 2019 , which was 1.3% higher than the third quarter 2018 distribution of $1.115 per unit and 10.2% higher than the fourth quarter 2017 distribution of $1.025 per unit. Total distributions related to 2018 were $4.40 per unit compared to $3.83 per unit total distributions related to 2017 , a 14.9% increase. Business Segment Results Operating segments are revenue-producing components of an enterprise for which separate financial information is produced internally and is subject to evaluation by the chief operating decision maker in deciding how to allocate resources. Other income and net interest expense are managed on a consolidated basis. EQM has presented each segment's operating income, equity income and various operational measures in the following sections. Management believes that the presentation of this information is useful to management and investors regarding the financial condition, results of operations and trends of its segments. EQM has reconciled each segment's operating income to EQM's consolidated operating income and net income in Note 5 to the consolidated financial statements. 54 Table of Contents GATHERING RESULTS OF OPERATIONS FINANCIAL DATA Firm reservation fee revenues Volumetric-based fee revenues Total operating revenues Operating expenses: Operating and maintenance Selling, general and administrative Depreciation Amortization of intangible assets Impairment of goodwill Total operating expenses Years Ended December 31, 2018 (a) 2017 (a) % Change 2016 % Change (Thousands, except per day amounts) $ 447,360 $ 549,710 997,070 79,477 92,020 98,678 41,547 261,941 573,663 407,355 102,612 509,967 45,325 45,052 44,957 5,540 — 140,874 369,093 9.8 $ 435.7 95.5 75.3 104.3 119.5 649.9 100.0 307.2 14.7 $ 339,237 58,257 397,494 37,751 39,678 30,422 — — 107,851 289,643 20.1 76.1 28.3 20.1 13.5 47.8 100.0 — 30.6 27.4 17.6 94.3 33.9 Operating income $ 423,407 $ OPERATIONAL DATA Gathering volumes (BBtu per day) Firm capacity reservation Volumetric-based services Total gathered volumes 2,044 4,445 6,489 1,826 816 2,642 11.9 444.7 145.6 1,553 420 1,973 Capital expenditures $ 717,251 $ 254,522 181.8 $ 295,315 (13.8) (a) Includes the pre-acquisition results of the October 2016 Transaction, the Drop-Down Transaction and the EQM-RMP Merger, which were effective on October 1, 2016, May 1, 2018 and July 23, 2018, respectively. The recasts are for the period the acquired businesses were under the common control of EQT. Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 Gathering operating revenues increased by $487.1 million in 2018 compared to 2017, driven primarily by the EQM-RMP Merger and the Drop-Down Transaction and production development in the Marcellus and Utica Shales. Firm reservation fee revenues increased primarily as a result of customers contracting for additional firm gathering capacity and higher rates on various wellhead expansion projects in 2018. Volumetric-based fee revenues increased due to increased volumes gathered under interruptible contracts, driven primarily by the EQM-RMP Merger and the Drop-Down Transaction, which contributed revenues of $238 million and $199 million, respectively, and increased volumes gathered in excess of firm contracted capacity. Gathering operating expenses increased by $432.8 million in 2018 compared to 2017, driven primarily by impairment of goodwill of $261.9 million and expenses incurred by the EQM-RMP Merger and the Drop-Down Transaction of $92.6 million and $71.8 million, respectively. Operating and maintenance expense increased due to the full-year recognition of compressor-related expenses associated with compression assets acquired in the EQM-RMP Merger and the Drop- Down Transaction of $18.4 million, increased personnel costs related primarily to increased employee headcount of $5.3 million, higher contracted labor of $3.1 million and higher reserves of $2.1 million. Selling, general and administrative expense increased due to increased overhead allocations following the EQM-RMP Merger and the Drop-Down Transaction and transaction costs of $7.8 million related to these transactions. Depreciation expense increased $48.7 million due to a full year of depreciation incurred on the assets acquired in the EQM-RMP Merger and the Drop-Down Transaction and from the additional assets placed in service during 2018. Amortization of intangible assets relates to customer contract intangible assets acquired in the Drop-Down Transaction. See "Outlook" and Note 1 to the consolidated financial statements for further discussion of the impairment of goodwill. 55 Table of Contents Year Ended December 31, 2017 Compared to Year Ended December 31, 2016 Gathering operating revenues increased by $112.5 million in 2017 compared to 2016, driven primarily by the EQM-RMP Merger and the Drop-Down Transaction and third-party and EQT production development in the Marcellus Shale. Firm reservation fee revenues increased primarily as a result of third parties and EQT contracting for additional firm gathering capacity, which increased by approximately 475 MMcf per day following the completion of the Range Resources header pipeline project and various EQT wellhead gathering expansion projects in 2017. The increase in volumetric-based fee revenues was driven primarily by revenue of $55.4 million associated with the EQM-RMP Merger and the Drop-Down Transaction for the period subsequent to EQT's acquisition of Rice Energy on November 13, 2017, partly offset by lower EQT volumes gathered in excess of firm contracted capacity and lower volumetric-based fee revenues under interruptible contracts due to an increase in contracts for firm gathering capacity. Gathering operating expenses increased by $33.0 million in 2017 compared to 2016, driven primarily by $20.5 million of expenses incurred as a result of the EQM- RMP Merger and the Drop-Down Transaction, higher personnel costs and increased property taxes. Selling, general and administrative expense increased due to expenses associated with the EQM-RMP Merger and the Drop-Down Transaction for the period subsequent to the Rice Merger. Depreciation expense increased $8.4 million due to additional assets placed in service, including those associated with the Range Resources header pipeline project and various EQT wellhead gathering expansion projects, and $6.2 million from depreciation expense associated with the EQM-RMP Merger and the Drop-Down Transaction for the period subsequent to the Rice Merger. Amortization of intangible assets relates to customer contracts associated with the Drop-Down Transaction.

Firm reservation fee revenues increased due to higher contractual rates on existing contracts with customers in 2018 and customers contracting for additional firm transmission capacity. Volumetric-based fee revenues increased due to increased volumes transported under firm contracts. 56 Table of Contents Transmission operating expenses decreased by $3.3 million in 2018 compared to 2017 primarily due to a non-cash charge of $10.5 million recorded in 2017 to depreciation related to the revaluation of differences between the regulatory and tax bases in EQM's regulated property, plant and equipment, partially offset by an increase in operating and maintenance expense associated with increased personnel costs, which were primarily associated with the growth of the business. Equity income increased by $39.6 million in 2018 compared to 2017 due to the increase in the MVP Joint Venture's AFUDC on the MVP as a result of continued spending on the project. Year Ended December 31, 2017 Compared to Year Ended December 31, 2016 Transmission operating revenues increased by $37.2 million in 2017 compared to 2016. Firm reservation fee revenues increased due to EQT and third parties contracting for additional firm transmission capacity, primarily on the OVC, as well as higher contractual rates on existing contracts in 2017. Higher firm transmission capacity on the OVC and reduced throughput on interruptible contracts resulted in lower volumetric-based fee revenues, partly offset by increased storage and parking revenue, which does not have associated pipeline throughput. Transmission operating expenses increased by $28.0 million in 2017 compared to 2016 primarily due to property taxes on the OVC and higher personnel costs. Selling, general and administrative expenses decreased primarily due to lower corporate allocations from EQT as a result of EQT's shift in focus during 2017 from midstream drop-down transactions to upstream asset and corporate acquisition projects. Depreciation expense increased as a result of the OVC project being placed in service in the fourth quarter of 2016 and a non-cash charge of $10.5 million recorded in 2017 to depreciation related to the revaluation of differences between the regulatory and tax bases in EQM's regulated property, plant and equipment. The related regulatory liability will be amortized over the estimated useful life of the underlying property of 43 years. Equity income increased by $12.3 million in 2017 compared to 2016 due to the increase in the MVP Joint Venture's AFUDC on the MVP as a result of continued spending on the project.

The recast is for the period the acquired businesses were under the common control of EQT, which began on November 13, 2017 as a result of the Rice Merger. Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 Water operating revenues increased by $97.6 million in 2018 compared to 2017, as a result of a full year of revenue earned from water services associated with the water assets acquired in the EQM-RMP Merger. The pre-acquisition results were retrospectively recast through the date of common control on November 13, 2017. 57 Table of Contents Water operating expenses increased by $64.1 million in 2018 compared to 2017, as a result of a full year of operating expenses incurred from water services associated with the water assets acquired in the EQM-RMP Merger. The pre-acquisition results were retrospectively recast through the date of common control on November 13, 2017. Year Ended December 31, 2017 Compared to Year Ended December 31, 2016 Water operating revenues increased by $13.6 million in 2017 compared to 2016, consisting of revenue earned from water services associated with the water assets acquired in the EQM-RMP Merger and the Drop-Down Transaction. The pre-acquisition results were retrospectively recast through the date of common control on November 13, 2017. Water operating expenses increased by $9.5 million in 2017 compared to 2016, consisting of operating expenses incurred from water services associated with the water assets acquired in the EQM-RMP Merger and the Drop Down Transaction. Operating expenses were composed of customary expenses for a water service business, including water procurement costs. The pre-acquisition results were retrospectively recast through the date of common control on November 13, 2017. Other Income Statement Items Other income Other income increased $0.6 million for the year ended December 31, 2018 compared to year ended December 31, 2017 due to increased AFUDC – equity. Other income decreased by $22.7 million for the year ended December 31, 2017 compared to the year ended December 31, 2016 driven primarily by decreased AFUDC – equity of $14.3 million associated with the OVC being placed in service in the fourth quarter of 2016 and distributions from EES of $8.3 million . As discussed in Note 1 to the consolidated financial statements, effective October 1, 2016, the accounting for EQM's investment in EES converted from a cost method investment to a note receivable. Beginning October 1, 2016, distributions received from EES are recorded partly as interest income and partly as a reduction in the note receivable. This change decreased the amount of other income recognized and increased interest income in the year ended December 31, 2017 compared to 2016. Net interest expense Net interest expense increased by $85.1 million for the year ended December 31, 2018 compared to the year ended December 31, 2017 due primarily to interest expense of $69.6 million on the 2018 Senior Notes, higher interest expense of $20.7 million on credit facility borrowings as well as higher interest and deferred issuance costs on the EQM Term Loan Facility, partly offset by increased capitalized interest and AFUDC - debt and interest income earned on cash on hand. Net interest expense increased by $20.2 million for the year ended December 31, 2017 compared to the year ended December 31, 2016 due primarily to higher interest expense on EQM's long-term debt issued in November 2016 of $17.4 million, lower capitalized interest and AFUDC - debt of $5.3 million from decreased spending on capital projects and increased interest on EQM's credit facility borrowings, partly offset by increased interest income recorded on distributions from EES of $5.1 million and higher interest income earned on cash on hand. Noncontrolling interest Net income attributable to noncontrolling interest for the year ended December 31, 2018 and for the period from November 13, 2017 through December 31, 2017 related to the 25% limited liability interest in Strike Force Midstream owned by Gulfport Midstream. As discussed in Note 2 , on May 1, 2018, EQM acquired this interest from Gulfport Midstream. As a result, EQM owned 100% of Strike Force Midstream effective as of May 1, 2018. See Note 12 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for discussion of income tax expense (benefit). See "Investing Activities" and "Capital Requirements" under "Capital Resources and Liquidity" for discussion of capital expenditures. 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; 58 Table of Contents • 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 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. 59 Table of Contents Net income attributable to EQM Add: Net interest expense Depreciation Amortization of intangible assets Impairment of goodwill (a) Income tax expense Preferred Interest payments (b) Non-cash long-term compensation expense Transaction costs Less: Equity income AFUDC – equity Pre-acquisition capital lease payments for AVC (c) Adjusted EBITDA attributable to RMP prior to merger (d) Adjusted EBITDA attributable to the Drop-Down Transaction (e) Adjusted EBITDA attributable to the October 2016 Acquisition (f) Adjusted EBITDA Less: Net interest expense excluding interest income on the Preferred Interest Capitalized interest and AFUDC – debt (g) Ongoing maintenance capital expenditures net of reimbursements (h) Transaction costs Distributable cash flow Net cash provided by operating activities Adjustments: Pre-acquisition capital lease payments for AVC (c) Capitalized interest and AFUDC – debt (g) Principal payments received on the Preferred Interest Ongoing maintenance capital expenditures net of reimbursements (h) Current tax expense Adjusted EBITDA attributable to RMP prior to merger (d) Adjusted EBITDA attributable to the Drop-Down Transaction (e) Adjusted EBITDA attributable to the October 2016 Acquisition (f) Other, including changes in working capital Distributable cash flow Years Ended December 31, 2018 2017 (Thousands) 2016 $ 668,002 $ 609,626 $ 537,954 122,094 171,914 41,547 261,941 — 10,984 1,275 7,761 (61,778) (5,570) — (160,128) (60,507) — 36,955 107,161 5,540 — — 10,984 242 — (22,171) (5,110) — (33,457) (20,272) — $ 997,535 $ 689,498 $ (124,198) (9,873) (46,939) (7,761) (42,999) (4,120) (27,609) — 16,766 62,691 — — 10,147 2,764 195 — (9,898) (19,402) (17,186) — — (11,420) 572,611 (18,506) (9,400) (21,434) — $ $ 808,764 $ 614,770 $ 523,271 1,187,239 $ 681,848 $ 537,904 — (9,873) 4,406 (46,939) — (160,128) (60,507) — (105,434) — (4,120) 4,166 (27,609) — (33,457) (20,272) — 14,214 $ 808,764 $ 614,770 $ (17,186) (9,400) 1,024 (21,434) 1,373 — — (11,420) 42,410 523,271 (a) As a result of annual goodwill impairment assessment, EQM recorded an impairment of goodwill of approximately $261.9 million . See "Outlook" and Note 1 for further information. (b) In conjunction with the October 2016 Acquisition, the operating agreement of EES was amended and the accounting for EQM's Preferred Interest in EES converted from a cost method investment to a note receivable effective October 1, 2016. There were no changes in the cash payments; however, distributions from EES subsequent to this amendment were recorded partly as a reduction in the note receivable and partly as interest income, which is included in net interest expense in the accompanying statements of consolidated operations. Distributions received from EES prior to this amendment in 2016 were included in other income in the accompanying statements of consolidated operations. (c) 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. 60 Table of Contents (d) Adjusted EBITDA attributable to RMP for the period prior to July 23, 2018 was excluded from EQM's adjusted EBITDA calculations as these amounts were generated by RMP prior to acquisition by EQM; therefore, the amounts could not be distributed to EQM's unitholders. Adjusted EBITDA attributable to RMP for the year ended December 31, 2018 and for the period from November 13, 2017 to December 31, 2017 was calculated as net income of $123.2 million and $25.1 million, respectively, plus net interest expense of $4.6 million and $0.8 million, respectively, depreciation of $31.4 million and $7.5 million, respectively, and non-cash compensation expense of $0.9 million and less than $0.1 million, respectively. (e) Adjusted EBITDA attributable to the Drop-Down Transaction for the period prior to May 1, 2018 was excluded from EQM's adjusted EBITDA calculations as these amounts were generated by assets acquired in the Drop-Down Transaction prior to acquisition by EQM; therefore, the amounts could not have been distributed to EQM's unitholders. Adjusted EBITDA attributable to the Drop-Down Transaction for the year ended December 31, 2018 and for the period from November 13, 2017 to December 31, 2018 was calculated as net income of $41.0 million and $12.6 million, respectively, plus depreciation of $5.8 million and $2.2 million, respectively, and amortization of intangible assets of $13.8 million and $5.5 million, respectively, less interest income of less than $0.1 million and $0.1 million, respectively. (f) 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 year ended December 31, 2016 was calculated as net income of $1.3 million plus depreciation of $2.1 million and income tax expense of $10.1 million, less interest income of $0.5 million and AFUDC - equity of $1.6 million. (g) As a result of increased significance of capitalized interest and AFUDC - debt in 2016, this line item was added as an adjustment to the calculation of distributable cash flow for the year ended December 31, 2016. (h) Ongoing maintenance capital expenditures are expenditures (including expenditures for the construction or development of new capital assets or the replacement, improvement or expansion of existing capital assets) made to maintain, over the long term, EQM's operating capacity or operating income. In the Predecessor period, EQT had reimbursement obligations to EQM for certain maintenance capital expenditures under the terms of the EQT Omnibus Agreement. For further explanation of these reimbursable maintenance capital expenditures, see "Capital Requirements." For the year ended December 31, 2016 , ongoing maintenance capital expenditures net of reimbursements excludes ongoing maintenance of $6.5 million attributable to AVC, Rager and the Gathering Assets prior to acquisition. See "Executive Overview" for a discussion of EQM's net income, the GAAP financial measure most directly comparable to adjusted EBITDA. Adjusted EBITDA increased by $308.0 million for the year ended December 31, 2018 compared to the year ended December 31, 2017 primarily as a result of the EQM-RMP Merger and the Drop-Down Transaction, which resulted in EBITDA subsequent to the transactions being reflected in adjusted EBITDA. Adjusted EBITDA increased $116.9 million for the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily as a result of higher operating income on increased revenues driven by production development in the Marcellus Shale and the acquisitions for each period, which resulted in EBITDA subsequent to the transaction being reflected in adjusted EBITDA, including the elimination of the AVC lease payment. Net cash provided by operating activities, the GAAP financial measure most directly comparable to distributable cash flow, increased by $505.4 million for the year ended December 31, 2018 compared to the year ended December 31, 2017 and $143.9 million for the year ended December 31, 2017 compared to the year ended December 31, 2016 as discussed in "Capital Resources and Liquidity." Distributable cash flow increased by $194.0 million for the year ended December 31, 2018 compared to the year ended December 31, 2017 and $91.5 million for the year ended December 31, 2017 compared to the year ended December 31, 2016 , in each case, mainly attributable to the increase in adjusted EBITDA, partly offset by increased net interest expense. Outlook EQM’s assets overlay core acreage in the prolific Appalachian Basin. The location of EQM’s assets allows it to access major demand markets in the U.S. EQM is one of the largest natural gas gatherers in the U.S. and holds a premier transmission footprint in the Appalachian Basin, and its largest customer, EQT, is the largest natural gas producer in the U.S. based on produced volumes. EQM maintains a stable cash flow profile, with over 50% of its revenue for the year ended December 31, 2018 generated by firm reservation fees. EQM’s principal strategy is to leverage its existing and planned growth projects and to seek and execute on strategically-aligned acquisition and joint venture opportunities to achieve the scale and scope of a top-tier midstream company. As part of its approach to organic growth, EQM is focused on building and completing its key gathering and transmission growth projects outlined under "Strategy" in "Item 1. Business," many of which are supported by contracts with firm capacity commitments. Additionally, EQM expects to achieve growth from its water service business and from volumetric gathering opportunities and transmission and storage services. The water service business is complementary to the gathering business, and EQM recognizes an opportunity to expand its existing asset footprint and is actively pursuing solutions for produced water handling. EQM is 61 Table of Contents also focused on optimizing and integrating its Pennsylvania gathering systems to create additional system gathering capacity and provide high- and low-pressure gathering solutions for its customers. EQM’s focus on execution of its organic projects, coupled with asset optimization efforts, disciplined capital spending and operating cost control, is complemented by EQM’s commitment to seek, evaluate and execute on strategically-aligned acquisition and joint venture opportunities. EQM believes that this approach will enable EQM to achieve its strategic goals. For further discussion of key growth projects, see "Strategy" in "Item 1. Business." For further discussion of capital expenditures, see "Capital Requirements." EQGP Unit Purchases.

The transactions contemplated by the Unit Purchase Agreements (the Unit Purchases) were completed on December 31, 2018 with respect to an aggregate of 14,560,281 EQGP common units (the Initial Unit Purchase Closing). Additional closings occurred on January 2, 2019 and January 3, 2019, pursuant to which Equitrans Midstream acquired the remaining 804,140 EQGP common units to be purchased pursuant to the Unit Purchase Agreements. The aggregate consideration paid by Equitrans Midstream pursuant to the Unit Purchase Agreements was $307.3 million. As a result of the Unit Purchases, Equitrans Midstream owned 291,373,187 EQGP common units, representing an approximate 96.3% limited partner interest, and the entire non-economic general partner interest in EQGP. Limited Call Right. Following the Initial Unit Purchase Closing, on December 31, 2018, Equitrans Midstream exercised the limited call right (the Limited Call Right) provided for in Section 15.1(a) of the Second Amended and Restated Agreement of Limited Partnership of EQGP, dated as of October 12, 2018, pursuant to which Equitrans Midstream purchased all outstanding EQGP common units (other than those owned by Equitrans Midstream and its affiliates) at a price per EQGP common unit equal to the Purchase Price. The Limited Call Right was completed on January 10, 2019. After giving effect to the exercise of the Limited Call Right, EQGP is an indirect wholly-owned subsidiary of Equitrans Midstream. Also on January 10, 2019, and following the Unit Purchases and the Limited Call Right (together, the EQGP Buyout), EQGP voluntarily withdrew the EQGP common units from listing on the New York Stock Exchange and from registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the Exchange Act). The EQGP Buyout was funded from the net proceeds of the Term Loan Credit Agreement (as defined below). See "EQM IDR Transaction" in "Item 1. Business." Goodwill Impairment. Following the third quarter of 2018 and prior to the Separation, EQM identified impairment indicators in the form of production curtailments announced by a primary customer of the two reporting units to which EQM's goodwill is recorded that could reduce volumetric-based fee revenues of those reporting units. For the year ended December 31, 2018, EQM determined that the carrying value of one of those reporting units (the RMP PA Gas Gathering reporting unit, which comprises the Pennsylvania gathering assets acquired in the Rice Merger) was greater than its fair value. As a result, EQM recognized an impairment of goodwill of $261.9 million . As of December 31, 2018, EQM had approximately $1.1 billion of goodwill, which will be monitored for future impairment. Management will continue to monitor and evaluate the factors underlying the fair market value of acquired businesses over the course of the year to determine if any interim assessments are necessary and will take any additional impairment charges required. See Note 1 to the consolidated financial statements for further information. Capital Resources and Liquidity EQM's principal liquidity requirements are to finance its operations, fund capital expenditures, potential acquisitions and other strategic transactions and capital contributions to the MVP Joint Venture, pay cash distributions and satisfy any indebtedness obligations. EQM's ability 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 interests. Pursuant to the tax matters agreement between Equitrans Midstream and EQT entered into in connection with the Separation, Equitrans Midstream is subject to certain restrictions related to certain corporate actions, including restrictions related to the issuance of Equitrans Midstream and EQM securities beyond certain thresholds. See “ Our general 62 Table of Contents partner may require us to forgo certain transactions in order to avoid the risk of Equitrans Midstream incurring material tax-related liabilities or indemnification obligations under Equitrans Midstream’s tax matters agreement with EQT .” under “Risks Inherent in an Investment in Us” included in “Item 1A. Risk Factors.” EQM is not forecasting any public equity issuance for currently anticipated organic growth projects. Operating Activities Net cash flows provided by operating activities were approximately $1.2 billion for the year ended December 31, 2018 compared to approximately $681.8 million for the year ended December 31, 2017 . The increase was driven primarily by higher operating income for which contributing factors are discussed in "Executive Overview" and "Business Segment Results" sections herein, partly offset by increased interest as discussed in the "Other Income Statement Items" section herein. Net cash flows provided by operating activities were approximately $681.8 million for the year ended December 31, 2017 compared to approximately $537.9 million for the year ended December 31, 2016 . The increase was driven by higher operating income for which the contributing factors are discussed in the "Executive Overview" and "Business Segment Results" sections herein and the timing of payments between the two periods, partly offset by increased interest as discussed in the "Other Income Statement Items" section herein. Investing Activities Net cash flows used in investing activities totaled approximately $3.0 billion for the year ended December 31, 2018 compared to approximately $535.5 million for the year ended December 31, 2017 . The increase was primarily attributable to the net assets acquired from EQT in the Drop-Down Transaction, increased capital expenditures as further described in "Capital Requirements" and increased capital contributions to the MVP Joint Venture consistent with the start of construction on the MVP and the purchase of interests in the MVP Southgate project. Net cash flows used in investing activities totaled approximately $535.5 million for 2017 as compared to approximately $732.0 million for 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 provided by financing activities totaled approximately $1.7 billion for the year ended December 31, 2018 compared to net cash flows used in financing activities of approximately $205.0 million for the year ended December 31, 2017 . For 2018 , the primary source of financing cash flows was net proceeds from EQM's 2018 Senior Notes offering, while the primary uses of financing cash flows were distributions paid to unitholders, net repayments on credit facilities and the Gulfport Transaction. For 2017 , the primary use of financing cash flows was distributions paid to unitholders and the primary source of financing cash flows was net borrowings on EQM's credit facilities. Net cash flows used in financing activities totaled approximately $205.0 million for the year ended December 31, 2017 compared to approximately $106.5 million for the year ended December 31, 2016 . For 2016, the primary uses of financing cash flows were distributions paid to unitholders, net repayments on EQM's credit facilities and the October 2016 Acquisition. For 2016, the primary sources of financing cash flows were from EQM debt and equity offerings. Capital Requirements The gathering, transmission and storage and water service businesses are capital intensive, requiring significant investment to develop new facilities and to maintain and upgrade existing operations.

(b) EQM accrues capital expenditures when capital work has been completed but the associated bills have not yet been paid. Accrued capital expenditures are excluded from the statements of consolidated cash flows until they are paid. Expansion capital expenditures are expenditures incurred for capital improvements that EQM expects will increase its operating income or operating capacity over the long term. In 2018, expansion capital expenditures related primarily to capital expenditures invested in the assets acquired in the EQM-RMP Merger and the Drop-Down Transaction and in the following projects: the Hammerhead project, the Equitrans, L.P. Expansion project and various wellhead gathering expansion projects, partly offset by decreased spending on the Range Resources header pipeline project. In 2017, expansion capital expenditures related primarily to the following projects: various wellhead gathering expansion projects, the Range Resources header pipeline project and the AVC expansion project. In 2016, expansion capital expenditures related primarily to the following projects: the OVC project, the Range Resources header pipeline project, the NWV Gathering expansion project and the AVC expansion project. The OVC project was placed in service during the fourth quarter of 2016 and the Range Resources header pipeline project was placed in service in several phases beginning in the fourth quarter of 2016 and ending in the second quarter of 2017. Maintenance capital expenditures are expenditures made to maintain, over the long term, EQM's operating capacity or operating income. Examples of maintenance capital expenditures are expenditures to repair, refurbish and replace pipelines, to connect new wells to maintain throughput, to maintain equipment reliability, integrity and safety and to address environmental laws and regulations. Maintenance capital expenditures increased by $8.6 million in 2018 compared to 2017 and $14.0 million in 2017 compared to 2016 primarily as a result of additional assets in service and timing of ongoing maintenance projects. Included in maintenance capital expenditures are funded regulatory compliance capital expenditures. Prior to the Separation, for the period from January 1, 2018 through November 12, 2018 and for the years ended December 31, 2017 and 2016 , EQM was reimbursed by EQT under the terms of the EQT Omnibus Agreement $3.9 million , $15.5 million and $0.6 million , respectively, which is included in maintenance capital expenditures. Under the EQT Omnibus Agreement, for a period of ten years after the closing of EQM's IPO, EQT has agreed to reimburse EQM for plugging and abandonment expenditures for certain identified wells of EQT and third parties. Additionally, EQT has agreed to reimburse EQM for bare steel replacement capital expenditures in the event that ongoing maintenance capital expenditures (other than capital expenditures associated with plugging and abandonment liabilities to be reimbursed by EQT) exceed $17.2 million (with respect to EQM's assets owned at the time of the IPO) in any year. If such ongoing maintenance capital expenditures and bare steel replacement capital expenditures exceed $17.2 million during a year, EQT will reimburse EQM for the lesser of (i) the amount of bare steel replacement capital expenditures during such year and (ii) the amount by which such ongoing capital expenditures and bare steel replacement capital expenditures exceeds $17.2 million. This bare steel replacement reimbursement obligation is capped at an aggregate amount of $31.5 million over the ten years following EQM's IPO. Since EQM's IPO, EQM has been reimbursed approximately $30.7 million for bare steel replacement capital expenditures by EQT. Amounts reimbursed are recorded as capital contributions when received. See Note 6 for further information. In connection with the Separation, Equitrans Midstream assumed all of EQT’s obligations to indemnify and reimburse EQM under the EQT Omnibus Agreement, other than for those losses or expenses relating to or arising from plugging and abandonment obligations. Please read Item 13, “Certain Relationships and Related Transactions, and Director Independence—Agreements with EQT—Omnibus Agreement." In 2019 , EQM expects to make capital contributions to the MVP Joint Venture of approximately $0.9 billion depending on the timing of the construction of the MVP and MVP Southgate projects. Expansion capital expenditures are expected to be approximately $1.1 billion and maintenance capital expenditures are expected to be approximately $60 million, net of reimbursements. EQM's future capital investments may vary significantly from period to period based on the available investment opportunities and the timing of the construction of the MVP and MVP Southgate projects. Maintenance 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, borrowings under its credit facilities, debt offerings and issuances of additional EQM partnership units. EQM is not forecasting any public equity issuance for currently anticipated organic growth projects. EQM does not forecast capital expenditures associated with potential projects that are not committed as of the filing of this Annual Report on Form 10-K. Credit Facility Borrowings See Note 10 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for discussion of EQM's credit facilities. 64 Table of Contents Security Ratings The table below sets forth the credit ratings for debt instruments of EQM at December 31, 2018 . Rating Service Moody's S&P Fitch Senior Notes Ba1 BBB- BBB- Outlook Stable Stable 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, are considered non-investment grade. Distributions See Note 8 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for discussion of distributions. Schedule of Contractual Obligations The following represents EQM's contractual obligations as of December 31, 2018 . Purchase obligations exclude EQM's future capital contributions to the MVP Joint Venture and purchase obligations of the MVP Joint Venture.

(b) Interest payments exclude interest related to the credit facility borrowings as the interest rate on the credit facility borrowings is variable. (c) See Note 14 for additional information. (d) Operating leases are primarily entered into for various office locations and warehouse buildings, as well as lease obligations for compression equipment under existing contracts with third parties. Commitments and Contingencies In the ordinary course of business, various legal and regulatory claims and proceedings are pending or threatened against EQM and its subsidiaries. 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 incurred. EQM establishes reserves whenever it believes it to be appropriate for pending matters. Furthermore, after consultation with counsel and considering 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 quarterly cash distributions. See " The regulatory approval process for the construction of new midstream assets is challenging, and recent decisions by regulatory and judicial authorities in pending proceedings could impact EQM's or the MVP Joint Venture's ability to obtain 65 Table of Contents all approvals and authorizations necessary to complete certain projects on the projected time frame or at all or EQM's ability to achieve the expected investment return on the project. " under "Risk Factors – Risks Inherent in our Business" included in "Item 1A. Risk Factors" and see "Item 3. Legal Proceedings" for discussion of litigation and regulatory proceedings related to the MVP project. See Note 14 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for further discussion of EQM's commitments and contingencies. Off-Balance Sheet Arrangements See Note 7 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K for discussion of the MVP Joint Venture guarantees. Recently Issued Accounting Standards Recently issued accounting standards relevant to EQM are described in Note 1 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K. Critical Accounting Policies and Estimates EQM's significant accounting policies are described in Note 1 to the consolidated financial statements. Preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the related disclosures of contingent assets and liabilities. The following critical accounting policies, which were reviewed by EQM's Audit Committee, relate to its more significant judgments and estimates used in the preparation of its consolidated financial statements. Actual results could differ from those estimates. Property, Plant and Equipment. Determination of depreciation requires judgment regarding the estimated useful lives and salvage values of property, plant and equipment. EQM has not historically experienced material changes in its results of operations from changes in the estimated useful lives or salvage values of its property, plant and equipment; however, these estimates are reviewed periodically, including each time Equitrans, L.P. files with the FERC for a change in transmission and storage rates. Determination of internal costs capitalized requires judgment as to the percent of time spent on capitalized projects for the capitalization of costs such as salaries, benefits and other indirect costs. EQM believes that the accounting estimates related to depreciation and capitalization of internal costs are "critical accounting estimates" because they are susceptible to change. These assumptions affect the gross property, plant and equipment balances and the amount of depreciation and operating expense and, if changed, would have an effect on the results of operations and financial position. See Note 1 to the consolidated financial statements for additional information. Impairments of Long-lived Assets. Any accounting estimate related to impairment of property, plant and equipment, finite-lived intangible assets or an investment in an unconsolidated entity may require EQM's management to make assumptions about future cash flows, discount rates, the fair value of investments and whether losses in the value of its investments are other than temporary. Management's assumptions about future cash flows require significant judgment because actual operating levels have fluctuated in the past and are expected to fluctuate in the future. Additionally, management's assumptions about the fair value of its investment in an unconsolidated entity require significant judgment because EQM's investment is not traded on an active market. During the fourth quarter of 2018, the goodwill impairment (as discussed in Note 1) indicated that the carrying value of EQM's long-lived assets may not be recoverable. Accordingly, EQM reviewed its long-lived assets for impairment; however, the carrying value of the assets was found to be less than the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets, and so an impairment was not recorded. See Note 1 to the consolidated financial statements. EQM has not historically had indications of impairments; however, EQM believes that the accounting estimates related to impairments are "critical accounting estimates" because they require assumptions that are susceptible to change. Any potential impairment would have an effect on the results of operations and financial position. See Note 1 to the consolidated financial statements for additional information. Allocated General and Administrative Costs. General and administrative costs and operating and maintenance costs are allocated to EQM based on the nature of the expenses incurred by EQT in the Predecessor period and Equitrans Midstream in the Successor period. Costs that are directly related to EQM are directly charged to EQM. Other costs are allocated based on operational and financial metrics. Allocations are based on estimates and assumptions that management believes are reasonable; however, EQM believes that the accounting estimates related to allocated costs are "critical accounting estimates" because different estimates and assumptions would change the amounts allocated to EQM and those differences could be material. 66 Table of Contents These assumptions affect the amount of general and administrative expense and operating and maintenance expense and would have an effect on the results of operations if changed. See Notes 1 and 6 to the consolidated financial statements for additional information. Regulatory Accounting. Determination and application of regulatory accounting requires judgment regarding probability that certain expenses and income will be allowed in the rate setting process in a period different from the period in which they would have been reflected in the statements of consolidated operations for a non-regulated entity. EQM has not historically experienced material changes in its results of operations from changes in regulatory accounting; however, these estimates are reviewed periodically, including each time Equitrans, L.P. files with the FERC for a change in transmission and storage rates. EQM believes that the accounting estimates related to regulatory accounting are "critical accounting estimates" because they are susceptible to change. These assumptions affect the gross regulatory assets and liabilities and the amount of regulated operating revenues and expenses and would have an effect on the results of operations and financial position if changed. See Note 1 and Note 11 to the consolidated financial statements for additional information. Contingencies. EQM is involved in various regulatory and legal proceedings that arise in the ordinary course of business. A liability is recorded for contingencies based on EQM's assessment that a loss is probable and that the amount of the loss can be reasonably estimated. EQM considers many factors in making these assessments, including the history and specifics of each matter. Estimates are developed in consultation with legal counsel and are based on an analysis of potential results. EQM believes that the accounting estimates related to contingencies are "critical accounting estimates" because it must assess the probability and amount of loss related to contingencies. Future results of operations could be materially affected by changes in the assumptions. See Notes 1 and 14 for additional information. Revenue Recognition. Revenue from the gathering, transmission and storage of natural gas is generally recognized when the service is provided. Revenue from water services is generally recognized when water is delivered. Revenue related to services provided but not yet billed is estimated each month. These estimates are generally based on contract data, preliminary throughput and allocation measurements. Final bills for the current month are billed and collected in the following month. See Notes 1 and 3 to the consolidated financial statements for additional information. EQM records a monthly provision for accounts receivable that are considered uncollectible. In order to calculate the appropriate monthly provision, a historical rate of accounts receivable losses as a percentage of total revenue is used. This historical rate is applied to the current revenues on a monthly basis and is updated periodically based on events that may change the rate, such as a significant change to the natural gas industry or to the economy as a whole. Management reviews the adequacy of the allowance on a quarterly basis using the assumptions that apply at that time. While EQM has not historically experienced material bad debt expense, declines in the market price for natural gas combined with the increase in customers on EQM's systems may result in a greater exposure to potential losses than management's current estimates. As of December 31, 2018 , EQM had accounts receivable of $254.4 million , net of an allowance for doubtful accounts of $0.1 million . EQM believes that the accounting estimates related to revenue recognition are "critical accounting estimates" because estimated volumes are subject to change based on actual measurements, including prior period adjustments. In addition, EQM believes that the accounting estimates related to the allowance for doubtful accounts receivable are "critical accounting estimates" because the underlying assumptions used for the allowance can change and the actual mix of customers and their ability to pay may vary significantly from management's estimates, which could affect the collectability of customer accounts. These accounting estimates could potentially have a material effect on the results of operations and financial position. Business Combinations. EQM recorded the Rice Merger using the acquisition method of accounting; accordingly, the value assigned to the assets and liabilities of Rice Midstream Holdings LLC (Rice Midstream Holdings) are based on EQT's purchase accounting estimates. Accounting for the acquisition of a business requires a company to record the acquired identifiable assets and liabilities at fair value. The estimated fair value of midstream facilities and equipment, which generally consist of pipeline systems and compression stations, is estimated using the cost approach, which incorporates assumptions about the replacement costs for similar assets, the relative age of the assets and any potential economic or functional obsolescence. The fair values of the intangible assets are estimated using the multi-period excess earnings model, which estimates revenues and cash flows derived from the intangible asset and then deducts portions of cash flow that can be attributed to supporting assets otherwise recognized. Given the time required to obtain pertinent information necessary to finalize the allocation of the purchase price to the acquired net assets, the purchase price allocation may remain preliminary for a period of time before the required fair value estimates are finalized. Accordingly, it is not uncommon for the initial estimates to be subsequently revised. During the fourth quarter of 2018, the Rice Merger purchase price accounting was finalized. See Note 2 to the consolidated financial statements for further information. 67 Table of Contents EQM believes that the accounting estimates related to business combinations are "critical accounting estimates" because in determining the fair value of assets acquired, assumptions must be made about projections regarding the timing and amount of future development and operating costs and projections of replacement cost of and future cash flows from midstream assets and cash flows from customer relationships. Different assumptions may result in materially different values for these assets, which would affect EQM's future results of operations and financial position. Goodwill. Goodwill is the cost of an acquisition less the fair value of the identifiable net assets of the acquired business. At November 13, 2017, approximately $1.4 billion of goodwill was allocated to Rice Midstream Holdings as a result of the Rice Merger and was recognized by EQM following the EQM-RMP Merger and the Drop-Down Transaction. Prior to these transactions, EQM had no goodwill. See Note 1 for further information. Goodwill is evaluated for impairment at least annually or whenever events or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit is less than its carrying amount. EQM uses a combination of an income and market approach to estimate the fair value of a reporting unit. In the fourth quarter of 2018, EQM determined that a goodwill impairment indicator existed prior to its annual assessment date of November 30, 2018. As a result of the evaluation, which quantitatively considered the production curtailments announced by a primary customer of the Rice Retained Midstream and RMP PA Gas Gathering reporting units, EQM recorded an impairment to goodwill of approximately $261.9 million . See Note 1 to the consolidated financial statements for further information. EQM believes that the accounting estimates related to goodwill are "critical accounting estimates" because estimating the fair value of reporting units requires considerable judgment. In addition, management's estimate of a reporting unit's future financial results is sensitive to changes in assumptions, such as changes in stock prices, weighted-average cost of capital, terminal growth rates and industry multiples. EQM believes the estimates and assumptions used in estimating its reporting units' fair values are reasonable and appropriate, however, different assumptions and estimates could materially affect the calculated fair value and the resulting conclusion on impairment of goodwill, which could materially affect EQM's results of operations and financial position. Additionally, actual results could differ from these estimates. EQM performed a sensitivity analysis for each reporting unit to quantify the effect of certain changes to assumptions used in the goodwill assessment. While not impaired as of December 31, 2018, it was determined that a 1% increase to the weighted average cost of capital (WACC) and a corresponding 1% decrease to the terminal cash flow growth rate would have resulted in EQM's recognition of approximately $13.8 million of impairment of goodwill associated with the Rice Retained Midstream reporting unit (defined and discussed in Note 1). In addition, a 1% increase to the WACC and a corresponding 1% decrease to the terminal cash flow growth rate would have resulted in EQM's recognition of approximately $114.4 million of additional impairment of goodwill associated with the RMP PA Gas Gathering reporting unit (defined and discussed in Note 1). Item 7A. Quantitative and Qualitative Disclosures About Market Risk Interest Rate Risk . Changes in interest rates affect the amount of interest EQM earns on cash, cash equivalents and short-term investments and the interest rates EQM pays on borrowings under its credit facilities. EQM's senior notes are fixed rate and thus do not expose EQM to fluctuations in market interest rates. Changes in interest rates do affect the fair value of EQM's fixed rate debt. See Note 10 to the consolidated financial statements for discussion of EQM's borrowings and Note 1 to the consolidated financial statements for a discussion of fair value measurements. EQM may from time to time hedge the interest on portions of its borrowings under the credit facilities in order to manage risks associated with floating interest rates. Credit Risk. EQM is exposed to credit risk, which 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. Equitrans, L.P.'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. Approximately 82% of revenues were from investment grade counterparties for the year ended December 31, 2018 . 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. 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 December 31, 2018 , EQT's public senior debt had an investment grade credit rating. See Note 13 to the consolidated financial statements for further discussion regarding EQM's exposure to credit risk. 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 68 Table of Contents development of additional reserves and production that is accessible by EQM's pipeline and storage assets, or lower drilling activity, which would decrease demand for EQM's services. 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. EQM's customers may reduce capital spending in the future based on commodity prices or other factors. Unless EQM is successful in attracting and retaining new customers, its ability to maintain or increase the capacity subscribed and volumes transported under service arrangements on its transmission and storage system, the volumes gathered on its gathering systems, or the volumes of water provided by its water service business 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. For the year ended December 31, 2018 , approximately 54% of total revenues were generated from firm reservation fees under long-term contracts. As a result, EQM believes that short- and medium-term declines in volumes of gas produced, gathered, transported or stored on its systems will not have a significant effect on its results of operations, liquidity, financial position or ability to pay quarterly cash distributions because these firm reservation fees are paid regardless of volumes supplied to the system by customers. Longer term price declines could have an adverse effect on customer creditworthiness and related ability to pay firm reservation fees under long-term contracts which could affect EQM's results of operations, liquidity or financial position. Additionally, long-term declines in gas production in EQM's areas of operations would limit its growth potential. Other Market Risks. EQM's credit facility is underwritten by a syndicate of 21 financial institutions, each of which is obligated to fund its pro-rata portion of any borrowings by EQM. No one lender of the 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 the EQM's exposure to disruption or consolidation in the banking industry. 69 Table of Contents Item 8.

In our opinion, the financial statements present fairly, in all material respects, the consolidated financial position of the Partnership at December 31, 2018 and 2017, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Partnership's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 14, 2019 expressed an unqualified opinion thereon. Basis for Opinion These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ Ernst & Young, LLP We have served as the Partnership's auditor since 2012. Pittsburgh, Pennsylvania February 14, 2019 71 Table of Contents To the Unitholders of EQM Midstream Partners, LP and the Board of Directors of EQM Midstream Services, LLC Report of Independent Registered Public Accounting Firm Opinion on Internal Control over Financial Reporting We have audited EQM Midstream Partners, LP and subsidiaries’ internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria).

Basis for Opinion The Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young, LLP Pittsburgh, Pennsylvania February 14, 2019 72 Table of Contents EQM MIDSTREAM PARTNERS, LP AND SUBSIDIARIES STATEMENTS OF CONSOLIDATED OPERATIONS (a) YEARS ENDED DECEMBER 31, Operating revenues (b) Operating expenses: Operating and maintenance (c) Selling, general and administrative (c) Depreciation Amortization of intangible assets Impairment of goodwill Total operating expenses Operating income Equity income (d) Other income Net interest expense (e) Income before income taxes Income tax expense Net income Net income attributable to noncontrolling interest Net income attributable to EQM Calculation of limited partners interest in net income: Net income attributable to EQM Less pre-acquisition net income allocated to parent Less general partner interest in net income - general partner units Less general partner interest in net income - IDRs Limited partners' interest in net income Net income per limited partner unit – basic Net income per limited partner unit – diluted Weighted average limited partner units outstanding – basic Weighted average limited partner units outstanding – diluted Cash distributions declared per unit (f) 2018 2017 2016 (Thousands, except per unit amounts) $ 1,495,098 $ 895,558 $ 732,272 163,192 129,851 171,914 41,547 261,941 768,445 726,653 61,778 5,011 122,094 671,348 — 671,348 3,346 84,831 77,321 107,161 5,540 — 274,853 620,705 22,171 4,439 36,955 610,360 — 610,360 734 668,002 $ 609,626 $ 668,002 $ 609,626 $ (164,242) (6,104) (255,927) (37,722) (10,060) (143,531) 241,729 $ 418,313 $ 2.43 $ 2.43 $ 99,303 99,303 5.19 $ 5.19 $ 80,603 80,603 69,255 72,470 62,691 — — 204,416 527,856 9,898 27,113 16,766 548,101 10,147 537,954 — 537,954 537,954 (21,861) (9,173) (93,568) 413,352 5.21 5.21 79,367 79,388 4.40 $ 3.83 $ 3.19 $ $ $ $ $ $ (a) As discussed in Note 1 , EQM's consolidated financial statements have been retrospectively recast to include the pre-acquisition results of Allegheny Valley Connector, LLC (AVC), Rager Mountain Storage Company LLC (Rager) and certain gathering assets located in southwestern Pennsylvania and northern West Virginia (the Gathering Assets), which were acquired by EQM effective on October 1, 2016 (collectively, the October 2016 Acquisition), EQM Olympus Midstream LLC (EQM Olympus), Strike Force Midstream Holdings LLC (Strike Force) and EQM West Virginia Midstream LLC (EQM WV), which were acquired by EQM effective on May 1, 2018 (the Drop- Down Transaction), and Rice Midstream Partners LP (RMP), which was acquired by EQM effective on July 23, 2018 (the EQM-RMP Merger), because these transactions were between entities under common control at the time of acquisition.

Summary of Operations and Significant Accounting Policies Organization and Basis of Presentation EQM Midstream Partners, LP (formerly known as EQT Midstream Partners, LP) and subsidiaries (collectively, EQM) is a growth-oriented Delaware limited partnership formed by EQT in January 2012. EQM Midstream Services, LLC (formerly known as EQT Midstream Services, LLC) (the EQM General Partner) is a direct wholly owned subsidiary of EQGP Holdings, LP (formerly known as EQT GP Holdings, LP) (EQGP) and is the general partner of EQM. Following the consummation of the EQM IDR Transaction (as defined below), EQGP Services, LLC (formerly known as EQT GP Services, LLC), a wholly owned subsidiary of Equitrans Midstream, will be the general partner of EQM. References in these consolidated financial statements to Equitrans Midstream refer collectively to Equitrans Midstream Corporation and its consolidated subsidiaries. As discussed below, EQM's consolidated financial statements have been retrospectively recast to include the pre-acquisition results of the October 2016 Acquisition, the Drop-Down Transaction and the EQM-RMP Merger because these transactions were between entities under common control. On February 21, 2018, EQT announced its plan to separate its midstream business, which was composed of the separately-operated natural gas gathering, transmission and storage and water services of EQT (collectively, the Midstream Business), from its upstream business, which was composed of the natural gas, oil and natural gas liquids development, production and sales and commercial operations of EQT (collectively, the Upstream Business) (the Separation). On November 12, 2018, the Separation was effected through a series of transactions that culminated in EQT's contribution of the Midstream Business to Equitrans Midstream. See Note 4 for further information on the Separation. Post-Separation, Equitrans Midstream holds investments in the entities conducting the Midstream Business, including limited and general partner interests in EQGP, which, as of December 31, 2018, owned limited partner interests, the entire general partner interest and all of the incentive distribution rights (IDRs) in EQM. EQM does not have any employees. Operational, management and other services for EQM are provided by employees of Equitrans Midstream and its subsidiaries. Nature of Business EQM is a growth-oriented limited partnership that operates, acquires and develops midstream assets in the Appalachian Basin. EQM provides midstream services to its customers in Pennsylvania, West Virginia and Ohio through its three primary assets: the gathering system, which delivers natural gas from wells and other receipt points to transmission pipelines; the transmission and storage system, which delivers natural gas to local demand users and interstate pipelines for access to demand markets; and the water service system, which consists of water pipelines, impoundment facilities, pumping stations, take point facilities and measurement facilities that support well completion activities and collect flowback and produced water for recycling or disposal. As of December 31, 2018 , EQM's gathering system included approximately 700 miles of high-pressure gathering lines with total contracted firm reservation capacity of approximately 2.4 billion cubic feet ( Bcf ) per day, compression of approximately 333,000 horsepower and multiple interconnect points with EQM's transmission and storage system and to other interstate pipelines. EQM's gathering system also included approximately 1,500 miles of Federal Energy Regulatory Commission (FERC)-regulated, low-pressure gathering lines. As of December 31, 2018 , EQM's transmission and storage system included approximately 950 miles of FERC-regulated, interstate pipeline that have interconnect points to seven interstate pipelines and local distribution companies (LDCs). The transmission and storage system is supported by 41 compressor units, with total throughput capacity of approximately 4.4 Bcf per day and compression of approximately 120,000 horsepower, and 18 associated natural gas storage reservoirs, which have a peak withdrawal capacity of approximately 645 million cubic feet ( MMcf ) per day and a working gas capacity of approximately 43 Bcf . As of December 31, 2018 , EQM's water system included two independent systems composed of approximately 160 miles of pipeline that deliver fresh water from the Monongahela River, the Ohio River, local reservoirs and several regional waterways. The fresh water delivery services systems consist of permanent, buried pipelines, surface pipelines and fresh water storage facilities, as well as pumping stations and 28 fresh water impoundment facilities, which support fresh water transportation throughout the systems, and take point facilities and measurement facilities, which support well completion activities and collect and recycle or dispose flowback and produced water. 80 Table of Contents Significant Accounting Policies Principles of Consolidation : The consolidated financial statements include the accounts of all entities in which EQM holds a controlling financial interest. Investments over which EQM can exert significant influence, but not control, are recorded under the equity method of accounting. The consolidated financial statements reflect the pre-acquisition results of businesses acquired through common control transactions on a combined basis with EQM. See Note 2 . Transactions between EQM and EQT during the periods prior to the Separation (Predecessor period) and between EQM and Equitrans Midstream in the periods subsequent to the Separation (Successor period) period have been identified in the consolidated financial statements as transactions between related parties and are discussed in Note 6 . Segments: Operating segments are revenue-producing components of the enterprise for which separate financial information is produced internally and is subject to evaluation by EQM's chief operating decision maker in deciding how to allocate resources. Prior to the EQM-RMP Merger, EQM's operating activities were conducted through two business segments: Gathering and Transmission. Following the EQM-RMP Merger, EQM adjusted its internal reporting structure to incorporate the newly acquired assets consistent with how EQM's chief operating decision maker reviews EQM's business operations. EQM reports its operations in three segments that reflect its three lines of business of Gathering, Transmission and Water. The operating segments are evaluated based on their contribution to EQM's operating income and equity income. Transmission also includes EQM's investment in the MVP Joint Venture, which is treated as an equity investment for accounting purposes; as a result, Transmission's portion of the MVP Joint Venture's operating results is reflected in equity income and not in Transmission's operating income. All of EQM's operating revenues, income from continuing operations and assets are generated or located in the United States. See Note 5 . Reclassification: Certain previously reported amounts have been reclassified to conform to the current year presentation. Use of Estimates: The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (GAAP) requires management to make estimates and assumptions that affect amounts reported in these financial statements. Actual results could differ from those estimates. Cash Equivalents: EQM classifies highly-liquid investments with original maturities of three months or less as cash equivalents. Interest earned on cash equivalents is recorded as a reduction to net interest expense on the statements of consolidated operations. Accounts Receivables: Trade and other receivables are stated at their historical carrying amount. Judgment is required to assess the ultimate realization of accounts receivable, including assessing the probability of collection and the creditworthiness of customers. Based on assessments by management, allowances for doubtful accounts were $0.1 million and $0.4 million at December 31, 2018 and 2017 , respectively. EQM also has receivables due from EQT and Equitrans Midstream as discussed in Note 6 . Fair Value of Financial Instruments: EQM categorizes assets and liabilities disclosed at fair value using a three-level fair value hierarchy based on priority of the inputs used in the valuation. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). Owing to their short maturity, the carrying values of cash and cash equivalents, accounts receivable, amounts due to/from related parties and accounts payable are assumed to approximate fair value; as such, their fair values are Level 1 fair value measurements. Interest rates on credit facility borrowings are based on prevailing market rates, so the carrying values of the credit facility borrowings approximate fair value and the fair values are Level 1 fair value measurements. As EQM's senior notes are not actively traded, their fair values are estimated using an income approach model that applies a discount rate based on prevailing market rates for debt with similar remaining time-to-maturity and credit risk; as such, their fair values are Level 2 fair value measurements. See Note 10 . The fair value of the Preferred Interest is estimated using an income approach model that applies a discount rate based on prevailing market rates and is a Level 3 fair value measurement. As of December 31, 2018 and 2017 , the estimated fair value of the Preferred Interest was approximately $122 million and $133 million , respectively, and the carrying value of the Preferred Interest was approximately $115 million and $119 million , respectively, inclusive of $4.4 million , for each period, reported in other current assets in the consolidated balance sheets. Property, Plant and Equipment: EQM's property, plant and equipment are stated at depreciated cost. Maintenance projects that do not increase the overall life of the related assets are expensed as incurred. Expenditures that extend the useful life of the asset are capitalized. EQM capitalized internal costs of $54.4 million , $46.5 million and $53.2 million in the years ended December 31, 2018 , 2017 and 2016 , respectively. EQM capitalized interest, including the debt component of allowance for 81 Table of Contents funds used during construction (AFUDC), of $12.6 million , $4.7 million and $9.4 million in the years ended December 31, 2018 , 2017 and 2016 , respectively. The following table summarizes EQM's property, plant and equipment. Gathering assets Accumulated depreciation Net gathering assets Transmission and storage assets Accumulated depreciation Net transmission and storage assets Water services assets Accumulated depreciation Net water services assets Net other property, plant and equipment Net property, plant and equipment December 31, 2018 2017 (Thousands) $ 4,387,908 $ (247,720) 4,140,188 1,785,157 (286,693) 1,498,464 194,465 (26,489) 167,976 — 3,642,937 (153,791) 3,489,146 1,674,080 (248,474) 1,425,606 193,825 (3,363) 190,462 5,625 $ 5,806,628 $ 5,110,839 Depreciation is recorded using composite rates on a straight-line basis over the estimated useful life of the asset. The average depreciation rates for the years ended December 31, 2018 , 2017 and 2016 were 2.7% , 1.8% and 2.2% , respectively. EQM estimates that gathering and transmission pipelines have useful lives of 20 years to 65 years and compression equipment has useful lives of 20 years to 50 years . EQM estimates that water pipelines, pumping stations and impoundment facilities have useful lives of 10 years to 15 years. As circumstances warrant, depreciation estimates are reviewed to determine if any changes in the underlying assumptions are necessary. EQM re-evaluates depreciation rates for its regulated property, plant and equipment each time it files with the FERC for a change in transmission and storage rates. Impairment of Long-lived Assets. Whenever events or changes in circumstances indicate that the carrying value of its long-lived assets may not be recoverable, EQM reviews its long-lived assets for impairment by first comparing the carrying value of the asset to the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the assets. If the carrying value exceeds the sum of the undiscounted cash flows, EQM estimates and recognizes an impairment loss equal to the difference between the carrying value and fair value of the assets. During the fourth quarter of 2018, a triggering event occurred as a result of EQM's annual goodwill impairment evaluation, which required EQM to perform a recoverability test on its long-lived assets. No impairment was recorded as a result of the recoverability test. No impairment of any long-lived assets was indicated or recorded during the year ended December 31, 2017 and 2016 . Intangible Assets: Intangible assets are recorded under the acquisition method of accounting at their estimated fair values at the acquisition date, which are calculated as the present value of estimated future cash flows using a risk-adjusted discount rate. As a result of the Drop-Down Transaction, EQM recognized approximately $623.2 million in intangible assets. These intangible assets were valued by EQT based upon the estimated fair value of the customer contracts as of November 13, 2017. The customer contracts were assigned a useful life of 15 years and are amortized on a straight-line basis. Amortization expense recorded in the consolidated statements of operations for the years ended December 31, 2018 and 2017 was $41.5 million and $5.5 million , respectively. There was no amortization expense recognized for the year ended December 31, 2016. The estimated annual amortization expense over the next five years is $41.5 million . Intangible assets, net as of December 31, 2018 and 2017 are detailed below. Intangible assets Less: accumulated amortization Intangible assets, net December 31, 2018 December 31, 2017 $ $ (Thousands) 623,200 $ (47,087) 576,113 $ 623,200 (5,540) 617,660 82 Table of Contents Goodwill: Goodwill is the total consideration of an acquisition less the fair value of the identifiable, acquired net assets. As a result of the Drop-Down Transaction and the EQM-RMP Merger, EQM recorded goodwill to two reporting units within the Gathering segment. During the fourth quarter of 2018, the accounting for the acquisition of the Rice Merger was finalized, which resulted in an increase to EQM's goodwill balance of approximately $0.9 million . See Note 2 for further information. Goodwill is evaluated for impairment at least annually and whenever events or changes in circumstance indicate that the fair value of a reporting unit is less than its carrying amount. EQM may perform either a qualitative or quantitative assessment of potential impairment. EQM's qualitative assessment of potential impairment may result in the determination that a quantitative impairment analysis is not necessary. Under this elective process, EQM assesses qualitative factors to determine whether the existence of events or circumstances leads EQM to determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If after assessing the totality of events or circumstances, EQM determines it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing a quantitative analysis is not required. However, if EQM concludes otherwise, then it performs a quantitative impairment analysis. If EQM chooses not to perform a qualitative assessment, or if it chooses to perform a qualitative assessment but is unable to qualitatively conclude that no impairment has occurred, then EQM will perform a quantitative evaluation. In the case of a quantitative assessment, EQM estimates the fair value of the reporting unit with which the goodwill is associated and compares it to the carrying value. If the estimated fair value of a reporting unit is less than its carrying value, an impairment charge is recognized for the excess of the reporting unit's carrying value over its fair value. The two reporting units to which the EQM's goodwill is recorded are (i) Rice Retained Midstream, which comprises the Ohio gathering assets acquired in the Rice Merger and (ii) RMP PA Gas Gathering, which comprises the Pennsylvania gathering assets acquired the Rice Merger. Rice Retained Midstream and RMP PA Gas Gathering earn a substantial portion of their revenues from volumetric-based fees, which are sensitive to changes in their customers' development plans. Following the third quarter of 2018 and prior to the Separation, EQM identified impairment indicators in the form of production curtailments announced by a primary customer of the Rice Retained Midstream and RMP PA Gas Gathering reporting units that could reduce volumetric-based fee revenues of those reporting units. In estimating the fair value of its reporting units, EQM used a combination of the income approach and the market approach. EQM used the income approach’s discounted cash flow method, which applies significant inputs not observable in the public market (Level 3), including estimates and assumptions related to future throughput volumes, operating costs, capital spending and changes in working capital. EQM used the market approach’s comparable company method and reference transaction method. The comparable company method evaluates the value of a company using metrics of other businesses of similar size and industry. The reference transaction method evaluates the value of a company based on pricing multiples derived from similar transactions entered into by similar companies. For the year ended December 31, 2018, EQM determined that the fair value of the Rice Retained Midstream reporting unit was greater than its carrying value; however, the carrying value of the RMP PA Gas Gathering reporting unit exceeded its fair value. As a result, EQM recognized impairment of goodwill of approximately $261.9 million . As of December 31, 2018 , EQM’s goodwill balance was reduced to approximately $1.1 billion . Investment in Unconsolidated Entity: EQM reviews the carrying value of its investments in unconsolidated entities for impairment whenever events or changes in circumstances indicate that the carrying value may have declined in value. The impairment review involves comparing the investment's carrying value to its estimated fair value. If the carrying value exceeds the estimated fair value, EQM estimates and recognizes an impairment loss equal to the difference between the investment's carrying value and fair value. Preferred Interest. EQT Energy Supply, LLC, a subsidiary of EQT (EES), generates revenue by providing services to a local distribution company. Upon EQM's acquisition of the preferred interest in EES (the Preferred Interest) in April 2015 and through October 2016, the Preferred Interest was treated as a cost method investment for accounting purposes. In October 2016, the EES operating agreement was amended to provide for mandatory redemption of the Preferred Interest at the end of the preference period, which is expected to be December 31, 2034. As a result of the amendment, EQM's investment in EES converted from a cost method investment to a note receivable effective October 1, 2016. The change did not affect the carrying value of the instrument but did affect the financial statement classification and presentation of distributions from EES. Distributions from EES received prior to the amendment were included in other income in EQM's statements of consolidated operations; distributions received after the amendment are recorded partly as a reduction to the Preferred Interest and partly as interest income, which is included in net interest expense in EQM's statements of consolidated comprehensive income. Unamortized Debt Discount and Issuance Costs. EQM amortizes debt discounts and issuance costs over the term of the related borrowing. Costs incurred from the issuance and extension of revolving credit facilities, including EQM's $3 Billion Facility 83 Table of Contents (defined in Note 10) are presented in other assets in the consolidated balance sheets. Debt discounts and issuance costs for all other debt instruments are presented as a reduction to debt in the consolidated balance sheets. Gas Imbalances: Gas imbalances occur when the actual amount of gas delivered from a pipeline system or storage facility varies from the amount of gas scheduled for delivery. EQM values gas imbalances due to/from shippers and operators at current index prices. Gas imbalances are settled in-kind, subject to the terms of the FERC tariffs. As of December 31, 2018 and 2017 , gas imbalance receivables of $3.3 million and $5.2 million , respectively, were presented in other current assets, with offsetting amounts recorded to system gas, a component of property, plant and equipment, in the consolidated balance sheets. EQM classifies gas imbalances as current because they are expected to settle within one year. Asset Retirement Obligations (AROs): As a result of the EQM-RMP Merger, EQM has AROs related to its water system and to one of its compression stations, for which EQM recorded an associated liability and capitalized a corresponding amount to asset retirement costs. The liability relates to the expected future obligation to dismantle, reclaim and dispose of these assets and was estimated using the present value of expected future cash flows, adjusted for inflation and discounted at EQM's credit-adjusted, risk-free rate. The AROs are recorded in regulatory and other long-term liabilities in the consolidated balance sheets. The following table presents a reconciliation of the beginning and ending carrying amounts of EQM's AROs. AROs at beginning of period Liabilities assumed at Rice Merger Liabilities incurred Revisions to estimated liabilities (a) Accretion expense AROs at end of period December 31, 2018 2017 (Thousands) 9,321 $ — 231 1,928 455 11,935 $ — 9,286 — — 35 9,321 $ $ (a) Revisions to estimated liabilities reflect changes in retirement cost assumptions and to the estimated timing of liability settlement. EQM is not legally or contractually obligated to restore or dismantle its transmission and storage systems. EQM is legally required to operate and maintain these assets and intends to do so as long as supply and demand for natural gas exists, which EQM expects to continue into the foreseeable future. Therefore, EQM did not have any asset retirement obligations related to its transmission and storage assets as of December 31, 2018 and 2017 . Contingencies: EQM is involved in various regulatory and legal proceedings that arise in the ordinary course of business. A liability is recorded when the loss is probable and the amount of loss can be reasonably estimated. EQM considers many factors when making such assessments, including historical knowledge and matter specifics. Estimates are developed through consultation with legal counsel and analysis of the potential results. See Note 14 . Regulatory Accounting: EQM's regulated operations consist of interstate pipeline, intrastate gathering and storage operations subject to regulation by the FERC. Through the rate-setting process, rate regulation allows EQM to recover the costs of providing regulated services plus an allowed return on invested capital. Regulatory accounting allows EQM to defer expenses and income to its consolidated balance sheets as regulatory assets and liabilities when it is probable that those expenses and income will be allowed in the rate-setting process for a period other than the period that they would be reflected in a non-regulated entity's statements of comprehensive income. Regulatory assets and liabilities are recognized in EQM's statements of operations in the period that the underlying expenses and income are reflected in the rates charged to shippers and operators. EQM expects to continue to be subject to rate regulation that will provide for the recovery of deferred costs. See Note 11 . The following tables present the total regulated operating revenues and expenses and the regulated property, plant and equipment of EQM. Operating revenues Operating expenses Years Ended December 31, 2018 2017 (Thousands) 2016 $ $ 393,911 $ 140,832 $ 383,309 $ 143,614 $ 343,978 114,978 84 Table of Contents Property, plant and equipment Accumulated depreciation Net property, plant and equipment Revenue Recognition: See Note 3 . As of December 31, 2018 2017 (Thousands) 1,900,411 $ (317,988) 1,582,423 $ 1,787,656 (278,756) 1,508,900 $ $ AFUDC: EQM capitalizes the carrying costs of financing the construction of certain long-lived, regulated assets. Such costs are amortized over the asset's estimated useful life and include interest costs (the debt component of AFUDC) and equity costs (the equity component of AFUDC). The debt component of AFUDC is recorded as a reduction to net interest expense in the statements of consolidated operations, and the equity component of AFUDC is recorded in other income in the statements of consolidated operations. The debt component of AFUDC for the years ended December 31, 2018 , 2017 and 2016 was $1.0 million , $0.8 million and $2.4 million , respectively, and the equity component of AFUDC for the years ended December 31, 2018 , 2017 and 2016 was $5.6 million , $5.1 million and $19.4 million , respectively. Equity-Based Compensation: EQM awarded share-based compensation in connection with the EQT Midstream Services, LLC 2012 Long-Term Incentive Plan. The EQM share-based awards are paid in EQM common units; as such, EQM treats the awards as equity awards. The awards are recorded at fair value based on the published market price on the grant date. See Note 9 . Net Income per Limited Partner Unit : Net income per limited partner unit is calculated utilizing the two-class method by dividing the limited partner interest in net income by the weighted average number of limited partner units outstanding during the period. EQM's net income is allocated to the general partner and limited partners in accordance with their respective ownership percentages. Any common units issued during the period are included on a monthly weighted-average basis for the periods in which they were outstanding. Diluted net income per limited partner unit reflects the potential dilution that could occur if securities or agreements to issue common units, such as awards under the long-term incentive plan, were exercised, settled or converted into EQM common units. When it is determined that potential common units resulting from an award subject to performance or market conditions should be included in the diluted net income per limited partner unit calculation, the impact is reflected by applying the treasury stock method. Net income attributable to the October 2016 Acquisition, the Drop-Down Transaction and the EQM-RMP Merger for the periods prior to October 1, 2016, May 1, 2018 and July 23, 2018, respectively, was not allocated to the limited partners for purposes of calculating net income per limited partner unit as these pre-acquisition amounts were not available to the unitholders. The phantom units granted to the independent directors of the EQM General Partner will be paid in common units upon a director's termination of service on the EQM General Partner's Board of Directors. As there are no remaining service, performance or market conditions related to these awards, 19,249 , 20,959 and 17,196 phantom unit awards were included in the calculation of basic and diluted weighted average limited partner units outstanding for the years ended December 31, 2018 , 2017 and 2016 , respectively. Potentially dilutive securities included in the calculation of diluted weighted average limited partner units outstanding totaled zero , zero and 20,548 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Income Taxes: For federal and state income tax purposes, all income, expenses, gains, losses and tax credits generated flow through to EQM's unitholders; accordingly, there is no provision for income taxes for EQM. Net income for financial statement purposes may differ significantly from taxable income of unitholders because of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under EQM's partnership agreement. The aggregate difference in the basis of EQM's net assets for financial and tax reporting purposes cannot be readily determined because information regarding each partner's tax attributes is not available to EQM. See Note 11. Recently Issued Accounting Standards: In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2014-09, Revenue from Contracts with Customers . The standard requires entities to recognize revenue in a manner that depicts the transfer of goods or services to customers at an amount that reflects the consideration the entity expects in exchange for those goods or services. EQM adopted this standard on January 1, 2018 using the modified retrospective method of adoption. Adoption of the standard did not require an adjustment to the opening balance of equity. EQM has implemented processes and controls to review new contracts for appropriate accounting treatment in the context of the standard and to generate disclosures required under the standard. For the disclosures required by the standard, see Note 3 . 85 Table of Contents In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities . The standard primarily affects the accounting for equity investments, the accounting for financial liabilities measured under the fair value option and the presentation and disclosure of financial instruments and eliminates the cost method of accounting for equity investments. EQM adopted this standard in the first quarter of 2018 with no significant effect on its financial statements or related disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases . The standard requires entities to record assets and obligations for contracts currently recognized as operating leases. In July 2018, the FASB targeted improvements to ASU 2016-02 through its issuance of ASU No. 2018-11. This update provides entities with an optional transition method, which permits an entity to initially apply the standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The standard also allows for election of transition practical expedients. EQM adopted the standards on January 1, 2019 using the optional transition method of adoption. Adoption of the standards did not require an adjustment to the opening balance of equity. For leases with commencement dates prior to the effective date, EQM elected to apply the package of practical expedients that state (i) an entity need not reassess whether any expired or existing contracts are or contain leases, (ii) an entity need not reassess the lease classification for any expired or existing leases, and (iii) an entity need not reassess initial direct costs for any existing leases. EQM elected not to use hindsight in determining the lease term. Additionally, EQM elected not to assess whether existing or expired land easements that were not previously accounted for as leases under Topic 840 are or contain a lease under Topic 840. The quantitative impacts of the standards are dependent on the leases in force at the time of reporting. As a result, the evaluation of the effect of the standards on the results of operations and liquidity will extend over future periods. However, EQM does not expect the standards to have a significant effect on its results of operations or liquidity in 2019. On January 1, 2019, EQM recognized a right-of-use asset and corresponding lease liability of approximately $3 million on its consolidated balance sheet related to its facilities and compressor operating leases. EQM has no capital leases. Additional disclosures will be required to describe the nature, maturity and amount of EQM's lease liabilities, including the significant assumptions and judgments required to value its lease liabilities, and the accounting policy elections taken. EQM is using a lease accounting system to document its current population of contracts classified as leases, which will be updated as EQM's lease population changes. EQM is implementing processes and controls to review new lease contracts for appropriate accounting treatment in the context of the standards and to generate disclosures required under the standards, which EQM expects to disclose in its Quarterly Report on Form 10-Q for the first quarter of 2019. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. The standard amends guidance on reporting credit losses on assets held at amortized cost basis and available for sale debt securities. For assets held at amortized cost basis, this standard eliminates the probable initial recognition threshold and, in its place, requires entities to recognize the 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 of the standard that have the contractual right to receive cash. The standard will be effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. EQM is currently evaluating the effect this standard will have on its financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test of Goodwill Impairment . The standard simplifies the quantitative goodwill impairment test requirements by eliminating the requirement to calculate the implied fair value of goodwill. Instead, an entity would record an impairment charge based on the excess of a reporting unit's carrying value over its fair value. EQM adopted this standard in the first quarter of 2018 with no significant effect on its financial statements or related disclosures. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement, Changes to the Disclosure Requirements for Fair Value Measurement , which makes a number of changes to the hierarchy associated with Level 1, 2 and 3 fair value measurements and the related disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. EQM is currently evaluating the effect this standard will have on its financial statements and related disclosures but does not expect the adoption of this standard to have a material effect on its financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other: Internal-Use Software , which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting 86 Table of Contents arrangements that include an internal-use software license). This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. EQM early-adopted the standard using the prospective method of adoption on January 1, 2019. EQM does not expect the adoption of this standard to have a significant effect on its financial statements. 2 . Acquisitions and Mergers EQM-RMP Merger On April 25, 2018, EQM entered into an Agreement and Plan of Merger (the Merger Agreement) with RMP, Rice Midstream Management LLC, the general partner of RMP (the RMP General Partner), the EQM General Partner, EQM Acquisition Sub, LLC, a wholly owned subsidiary of EQM (Merger Sub), EQM GP Acquisition Sub, LLC, a wholly owned subsidiary of EQM (GP Merger Sub), and, solely for certain limited purposes set forth therein, EQT. Pursuant to the Merger Agreement, on July 23, 2018, Merger Sub and GP Merger Sub merged with and into RMP and the RMP General Partner, respectively, with RMP and the RMP General Partner surviving as wholly owned subsidiaries of EQM. Pursuant to the Merger Agreement, each RMP common unit issued and outstanding immediately prior to the effective time of the EQM-RMP Merger was converted into the right to receive 0.3319 EQM common units (the Merger Consideration), the issued and outstanding IDRs of RMP were canceled and each outstanding award of phantom units in respect of RMP common units fully vested and converted into the right to receive the Merger Consideration, less applicable tax withholding, in respect of each RMP common unit subject thereto. The aggregate Merger Consideration consisted of approximately 34 million EQM common units of which 9,544,530 EQM common units were received by an indirect wholly owned subsidiary of EQT. As a result of the EQM-RMP Merger, RMP's common units are no longer publicly traded. Drop-Down Transaction On April 25, 2018, EQT, Rice Midstream Holdings LLC (Rice Midstream Holdings), a wholly owned subsidiary of EQT, EQM and EQM Gathering Holdings, LLC (EQM Gathering), a wholly owned subsidiary of EQM, entered into a Contribution and Sale Agreement pursuant to which EQM Gathering acquired from EQT all of EQT's interests in EQM Olympus, Strike Force and EQM WV in exchange for an aggregate of 5,889,282 EQM common units and aggregate cash consideration of $1.15 billion , subject to working capital adjustments. EQM Olympus owns a natural gas gathering system that gathers gas from wells located primarily in Belmont County, Ohio. Strike Force owns a 75% limited liability company interest in Strike Force Midstream LLC (Strike Force Midstream). The Drop-Down Transaction closed on May 22, 2018 with an effective date of May 1, 2018. As a result of the recast associated with the EQM-RMP Merger and the Drop-Down Transaction, EQM recognized approximately $1,384.9 million of goodwill, all of which was allocated to two reporting units within the Gathering segment. The goodwill value was based on a valuation performed by EQT as of November 13, 2017 with regard to the Rice Merger. EQT recorded goodwill as the excess of the estimated enterprise value of RMP, EQM Olympus, Strike Force and EQM WV over the sum of the fair value amounts allocated to the assets and liabilities of RMP, EQM Olympus, Strike Force and EQM WV. Goodwill was attributed to additional growth opportunities, synergies and operating leverage within the Gathering segment. Prior to the recast, EQM had no goodwill. Following EQT's initial valuation, certain estimates used in the purchase price allocation were updated. The net impact of these measurement period adjustments increased goodwill by approximately $0.9 million . The purchase price allocation was finalized and the measurement period adjustments were recorded as current period adjustments. The following table summarizes the allocation of the fair value of the assets and liabilities of RMP, EQM Olympus, Strike Force and EQM WV as of November 13, 2017 through pushdown accounting from EQT, as well as certain measurement period adjustments made subsequent to EQT's initial valuation. 87 Goodwill and Purchase Price Allocation (Thousands) $ 4,014,984 132,459 623,200 2,265,900 118 (117,124) (266,000) (9,323) 2,629,230 1,385,754 261,941 1,123,813 Table of Contents Estimated fair value of RMP, EQM Olympus, Strike Force and EQM WV (a) Estimated Fair Value of Assets Acquired and Liabilities Assumed: Current assets (b) Intangible assets (c) Property and equipment, net (d) Other non-current assets Current liabilities (b) RMP $850 Million Facility (e) Other non-current liabilities (e) Total estimated fair value of assets acquired and liabilities assumed Goodwill as of November 13, 2017 (f) Impairment of goodwill Goodwill as of December 31, 2018 (a) Includes the estimated fair value attributable to noncontrolling interest of $166 million .

(f) Reflected the value of perceived growth opportunities, synergies and operating leverage anticipated through the acquisition and ownership of the acquired gathering assets as of November 13, 2017. As discussed in Note 1 , as a result of EQM's annual impairment assessment, EQM recorded a $261.9 million impairment of goodwill. As of December 31, 2018 , EQM’s goodwill balance was reduced to approximately $1.1 billion . Unaudited Pro Forma Information The following unaudited pro forma financial information presents EQM's results as though the Rice Merger had been completed at January 1, 2016. The pro forma financial information has been included for comparative purposes and is not necessarily indicative of the results that might have actually occurred had the Rice Merger taken place on January 1, 2016; furthermore, the financial information is not intended to be a projection of future results.

As a result, EQM owned 100% of Strike Force Midstream effective as of May 1, 2018. October 2016 Acquisition 88 Table of Contents On October 13, 2016, EQM entered into a Purchase and Sale Agreement with EQT pursuant to which EQM acquired from EQT 100% of the outstanding limited liability company interests of AVC and Rager as well as the Gathering Assets. The closing occurred on October 13, 2016 and was effective as of October 1, 2016. The total cash consideration of $275 million was funded by borrowings under EQM's credit facility. 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, EQM'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 $25.1 million of cumulative capital lease depreciation recorded for periods prior to the transaction was eliminated through equity at the time of the acquisition and the financial statements now reflect the depreciation expense based on the 40 year useful life. This adjustment increased previously reported net income by $5.2 million and $4.2 million for the years ended December 31, 2016 and 2015, respectively. In addition, because the effect of the recast of the financial statements resulted in the elimination of the capital lease obligation from EQM to AVC, the lease obligation portion of the consideration paid was recorded in financing activities in the statements of consolidated cash flows. RMP and the entities part of the Drop-Down Transaction and the October 2016 Acquisition were businesses and the related acquisitions were transactions 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 respective transactions. 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. This portion of the consideration was recorded in financing activities in the statements of consolidated cash flows. EQM recast its consolidated financial statements to retrospectively reflect the EQM-RMP Merger, the Drop-Down Transaction and the October 2016 Acquisition for the periods the acquired businesses were under the common control of EQT; 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. 3 . Revenue from Contracts with Customers As discussed in Note 1 , EQM adopted ASU No. 2014-09, Revenue from Contracts with Customers , on January 1, 2018 using the modified retrospective method of adoption. EQM applied the standard to all open contracts as of the date of initial application. Adoption of the standard did not require an adjustment to the opening balance of equity and did not materially change the amount or timing of EQM's revenues. For the years ended December 31, 2018 , 2017 and 2016 , all revenues recognized on EQM's statements of consolidated operations are from contracts with customers. As of December 31, 2018 and 2017 , all receivables recorded on EQM's consolidated balance sheets represent performance obligations that have been satisfied and for which an unconditional right to consideration exists. Gathering, Transmission and Storage Service Contracts. EQM provides gathering, transmission and storage services in two manners: firm service and interruptible service. Firm service is provided under firm contracts, which are contracts for gathering, transmission or storage services that generally obligate the customer to pay a fixed, monthly charge to reserve an agreed upon amount of pipeline or storage capacity regardless of the capacity used by the customer during each month. Volumetric-based fees can also be charged under firm contracts for each firm volume transported, gathered or stored as well as for volumes transported, gathered or stored in excess of the firm contracted volume. Interruptible service contracts include volumetric-based fees, which are charges for the volume of gas gathered, transported or stored and generally do not guarantee access to the pipeline or storage facility. These contracts can be short or long-term. Firm and interruptible contracts are billed at the end of each calendar month, with payment typically due within 21 days. Under a firm contract, EQM has a stand-ready obligation to provide the service over the life of the contract. The performance obligation for firm reservation fee revenue is satisfied over time as the pipeline capacity is made available to the customer. As such, EQM recognizes firm reservation fee revenue evenly over the contract period, using a time-elapsed output method to measure progress. The performance obligation for volumetric-based fee revenue is generally satisfied upon EQM's monthly billing to the customer for volumes gathered, transported or stored during the month. The amount billed corresponds directly to the value of EQM's performance to date as the customer obtains value as each volume is gathered, transported or stored. Certain of EQM's gas gathering agreements are structured with minimum volume commitments (MVCs), which specify minimum quantities for which a customer will be charged regardless of quantities gathered under the contract. Revenue is recognized for MVCs when the performance obligation has been met, which is the earlier of when the gas is gathered or when it is remote that the producer will be able to meet its MVC. 89 Table of Contents Water Service Contracts. Water service revenues represent fees charged by EQM for the delivery of fresh water to a customer at a specified delivery point and for the collection and recycling or disposal of flowback and produced water. All of EQM's water service revenues are generated under variable price per volume contracts. For fresh water service contracts, the only performance obligation in each contract is for EQM to provide water (usually a minimum daily volume of water) to the customer at a designated delivery point. For flowback and produced water, the performance obligation is collection and disposition of the water, which typically occur within the same day. Water service contracts are billed on a monthly basis, with payment typically due within 21 days. Summary of Disaggregated Revenues.

Operation and Management Services Agreement . EQM had an operation and management services agreement with EQT Gathering, LLC (EQT Gathering), an indirect wholly owned subsidiary of EQT, pursuant to which EQT Gathering provided EQM's pipelines and storage facilities with certain operational and management services. EQM reimbursed EQT Gathering for such services pursuant to the terms of the EQT Omnibus Agreement. The operation and management services agreement was replaced in its entirety by a secondment agreement with EQT (discussed below). Secondment Agreement with EQT . On December 7, 2017, EQT, EQT Gathering, Equitrans, L.P. (Equitrans), EQM and the EQM General Partner entered a Secondment Agreement (the EQT Secondment Agreement), pursuant to which available 93 Table of Contents employees of EQT and its affiliates could be seconded to EQM and its subsidiaries to provide operating and other services with respect to EQM's business under the direction, supervision and control of EQM or its subsidiaries.

Investment in Unconsolidated Entity Investment in the MVP Joint Venture In 2015, EQM assumed EQT's interest in MVP Holdco LLC (MVP Holdco), an indirect, wholly-owned subsidiary of EQM, which holds EQM's interest in the Mountain Valley Pipeline (the MVP). In January 2016, EQM sold an 8.5% ownership interest in the MVP. The sales of interests in the MVP were for consideration that represented the proportional amount of capital contributions made to the joint venture as of the transaction date. As of December 31, 2018, EQM is the operator of the MVP and owned a 45.5% interest in the MVP. The MVP Joint Venture is constructing the MVP, an estimated 300 -mile natural gas interstate pipeline that will span from northern West Virginia to southern Virginia. The MVP Joint Venture is 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 of the MVP Joint Venture because it does not 95 Table of Contents have the power to direct the activities that most significantly affect the MVP Joint Venture's economic performance. Certain business decisions, such as decisions to make distributions of cash, require a greater than 66 2/3% ownership interest approval, and no one member owns more than a 66 2/3% interest. In April 2018, the MVP Joint Venture announced the MVP Southgate project, a proposed 70 -mile interstate pipeline that will extend from the MVP at Pittsylvania County, Virginia to new delivery points in Rockingham and Alamance Counties, North Carolina. In the fourth quarter of 2018, EQM assumed a portion of Con Edison's ownership interest and purchased a portion of PSNC Energy's ownership interest in the MVP Southgate project for $11.3 million . As a result of these transactions, EQM's ownership interest increased from 32.7% to 47.2% . As of December 31, 2018 , EQM was the operator of the MVP Southgate pipeline and owned a 47.2% ownership interest in the MVP Southgate project. The MVP Joint Venture submitted the MVP Southgate certificate application to the FERC in November 2018. Subject to approval by the FERC, the MVP Southgate project has a targeted in-service date of the fourth quarter 2020. In November 2018, the MVP Joint Venture issued a capital call notice for the funding of the MVP to MVP Holdco for $167.4 million , of which $143.0 million was paid in January 2019 and $24.4 million is expected to be paid in March 2019. In addition, in December 2018, the MVP Joint Venture issued a capital call notice for the funding of the MVP Southgate project to MVP Holdco for $1.8 million , all of which is expected to be paid in March 2019. The capital contribution payable and the corresponding increase to the investment balance are reflected on the consolidated balance sheet as of December 31, 2018 . The interests in MVP and MVP Southgate are equity method investments for accounting purposes because EQM has the ability to exercise significant influence over the MVP Joint Venture's operating and financial policies. Accordingly, EQM records adjustments to the investment balance for contributions to or distributions from the MVP Joint Venture and for EQM's pro-rata share of MVP Joint Venture earnings. Equity income, which is primarily related to EQM's pro-rata share of the MVP Joint Venture's AFUDC on the construction of the MVP, is reported in equity income in EQM's statements of consolidated operations. Pursuant to the MVP Joint Venture's limited liability company agreement, EQM is obligated to issue a performance guarantee in favor of the MVP Joint Venture to provide performance assurances of MVP Holdco's obligations to fund its proportionate share of the construction budget for the MVP project. As of December 31, 2018 , EQM's maximum financial statement exposure related to the MVP Joint Venture was approximately $1.7 billion , which consisted of the investment in unconsolidated entity balance on the consolidated balance sheet as of December 31, 2018 and amounts that could have become due under EQM's performance guarantees as of that date. In January 2019, EQM issued a performance guarantee in an amount equal to 33% of EQM's proportionate share of the construction budget for the MVP project, which was $261 million at the time of issuance. The amount of the performance guarantee will decrease based on the capital contributions made by MVP Holdco to the MVP Joint Venture. In addition, in February 2019, EQM issued a performance guarantee of $14 million in favor of the MVP Joint Venture for the MVP Southgate project. Upon the FERC's initial release to begin construction of the MVP Southgate project, EQM's current MVP Southgate performance guarantee will be terminated, and EQM will be obligated to issue a new guarantee in an amount equal to 33% of EQM's proportionate share of the remaining capital obligations for the MVP Southgate project. The following tables summarize the audited financial statements of the MVP Joint Venture.

Cash Distributions Years Ended December 31, 2018 2017 (Thousands) 2016 $ $ 91,056 $ 44,786 135,842 $ 32,054 $ 16,674 48,728 $ 16,315 5,206 21,521 The EQM partnership agreement requires EQM to distribute all of its available cash to EQM unitholders within 45 days after the end of each quarter. Available cash generally means, for any quarter, all cash and cash equivalents on hand at the end of that quarter: • less , the amount of cash reserves established by the EQM General Partner to: • provide for the proper conduct of EQM's business (including reserves for future capital expenditures, anticipated future debt service requirements and refunds of collected rates reasonably likely to be refunded as a result of a settlement or hearing related to FERC rate proceedings or rate proceedings under applicable law subsequent to that quarter); • comply with applicable law, any of EQM's debt instruments or other agreements; or • provide funds for distributions to EQM's unitholders and to the EQM General Partner for any one or more of the next four quarters (provided that the EQM General Partner may not establish cash reserves for distributions if the effect of the establishment of such reserves will prevent EQM from distributing the minimum quarterly distribution on all common units); • plus , if the EQM General Partner so determines, all or any portion of the cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made subsequent to the end of such quarter. If for any quarter EQM has distributed available cash from operating surplus to the common unitholders in an amount equal to EQM's minimum quarterly distribution; then, EQM will distribute any additional available cash from operating surplus for that quarter among the unitholders and the EQM General Partner in the following manner: Minimum Quarterly Distribution First Target Distribution Second Target Distribution Third Target Distribution Thereafter Total Quarterly Distribution per Marginal Percentage Interest in Distributions Unit Target Amount Unitholders General Partner $0.35 Above $0.3500 up to $0.4025 Above $0.4025 up to $0.4375 Above $0.4375 up to $0.5250 Above $0.5250 98.2% 98.2% 85.2% 75.2% 50.2% 1.8% 1.8% 14.8% 24.8% 49.8% To the extent these incentive distributions are made to the EQM General Partner, more available cash proportionally is allocated to the EQM General Partner than to holders of limited partner units. On January 16, 2019 , the Board of Directors of the EQM General Partner declared a cash distribution to EQM's unitholders for the fourth quarter of 2018 of $1.13 per common unit. The cash distribution was paid on February 13, 2019 to unitholders of record at the close of business on February 1, 2019 . Cash distributions to EQGP were approximately $24.6 million related to its limited partner interest, $2.5 million related to its general partner interest and $72.7 million related to its IDRs. EQM IDR Transaction . On February 13, 2019, Equitrans Midstream entered into a definitive agreement and plan of merger with the EQM General Partner (the IDR Merger Agreement) and certain related parties, pursuant to which, among other things, Equitrans Midstream will exchange and cancel the IDRs and economic general partner interest in EQM that it holds, indirectly, for (a) 80 million newly-issued EQM common units and 7 million newly-issued Class B units (Class B units), both representing limited partner interests in EQM, and (b) the retention of a non-economic general partner interest in EQM (the EQM IDR Transaction). As a result of the EQM IDR Transaction, (i) EQGP Services, LLC will replace EQM Midstream Services, LLC as the general partner of EQM and (ii) the IDRs and economic general partner interest in EQM will be exchanged and canceled. 97 Table of Contents The Class B units will become convertible at the holder’s option in three tranches, with 2.5 million becoming convertible on April 1, 2021, 2.5 million becoming convertible on April 1, 2022, and 2 million becoming convertible on April 1, 2023 (each, a Class B unit conversion date). Until the applicable Class B unit conversion date, the Class B units will not be entitled to receive any distributions of available cash. After the applicable Class B unit conversion date, whether or not such Class B units have been converted into EQM common units, the Class B units will participate pro rata with the EQM common units in distributions of available cash. Furthermore, the Class B units will become convertible at the holder’s option into EQM common units immediately before a change of control of EQM. The holders of Class B Units will vote together with the holders of EQM’s common units as a single class, except that Class B Units owned by the general partner of EQM and its affiliates will be excluded from voting if EQM common units owned by such parties are excluded from voting. Holders of Class B Units will be entitled to vote as a separate class on any matter that adversely affects the rights or preferences of the Class B Units in relation to other classes of partnership interests in any material respect or as required by law. The completion of the EQM IDR Transaction is subject to certain conditions, including, among other things: (1) all required filings, consents, approvals, permits and authorizations of any governmental authority in connection with the EQM IDR Transaction having been made or obtained; (2) there being no law or injunction prohibiting the consummation of the EQM IDR Transaction; (3) subject to specified materiality standards, the accuracy of the representations and warranties of the other party; (4) compliance by the other party in all material respects with its covenants; and (5) the receipt by EQM and EQGP of certain opinions covering matters described in the partnership agreements of EQM and EQGP and in the IDR Merger Agreement with respect to the EQM IDR Transaction. The EQM IDR Transaction will be accomplished by merging a subsidiary of EQM with and into EQGP, with EQGP surviving as a wholly-owned subsidiary of EQM. EQM expects the EQM IDR Transaction to close in February 2019. After giving effect to the EQM IDR Transaction, Equitrans Gathering Holdings, LLC (Equitrans Gathering Holdings), EQM GP Corporation (EQM GP Corp) and Equitrans Midstream Holdings, LLC (EMH), each a subsidiary of Equitrans Midstream, will hold 89,505,616 , 89,536 and 27,650,303 of EQM’s common units, respectively, representing an aggregate 56.5% limited partner interest in EQM. Additionally, Equitrans Gathering Holdings, EQM GP Corp and EMH will hold 6,153,907 , 6,155 and 839,938 of Class B units, respectively, representing an aggregate 3.4% limited partner interest in EQM. In total, Equitrans Midstream expects to own, directly or indirectly, a 59.9% limited partner interest in EQM that consists of 117,245,455 EQM common units and 7,000,000 Class B units. 9 . Equity-Based Compensation Plan EQM Phantom Units. The EQM General Partner has granted phantom unit awards to certain non-employee directors of the EQM General Partner. The EQM phantom units vest upon grant, and the value of the EQM phantom units are paid in EQM common units upon the director's termination of service on the EQM General Partner's Board of Directors. The EQM phantom units are accounted for as equity awards; as such, EQM recognizes the fair value of the awards on the grant date as share-based compensation expense upon grant. As of December 31, 2018 , there were 17,470 EQM phantom units, including accrued distributions, outstanding. EQM granted 5,100 , 2,940 and 2,610 EQM phantom units during the years ended December 31, 2018, 2017 and 2016, respectively. The weighted average fair value of the grants, based on EQM's common unit price on the grant date, was $68.66 , $76.68 and $75.46 for the years ended December 31, 2018 , 2017 and 2016 , respectively. EQM recognized share-based compensation expense of $0.4 million , $0.2 million and $0.2 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. In July 2012, the EQM General Partner granted awards representing common units (EQM Total Return Program). The confirmed awards were distributed in EQM common units during the first quarter of 2016. In the first quarter of 2014, performance units under the 2014 EQM Value Driver Award Program (2014 EQM VDA) were granted to EQT employees who provided services to EQM. The first tranche of the confirmed awards were distributed in EQM common units in February 2015 and the remainder of the confirmed awards were distributed in EQM common units in February 2016. EQM common units to be delivered pursuant to vesting of the equity-based awards may be common units acquired by the EQM General Partner in the open market or from any other person, issued directly by EQM or any combination of the foregoing. RMP Phantom Units. Prior to the EQM-RMP Merger, the RMP General Partner granted phantom unit awards (RMP phantom units) to certain non-employee directors of the RMP General Partner. The RMP phantom units would cliff vest at the end of the requisite service period of approximately one year, and the value of the RMP phantom units were paid in RMP common units upon vesting. 98 Table of Contents The RMP phantom units were equity awards; as such, RMP recognized the fair value of the awards on the grant date as share-based compensation expense on a straight-line basis over the vesting period. As of July 23, 2018, in connection with the EQM-RMP Merger, the 36,220 RMP phantom units outstanding vested and converted into 12,024 EQM common units based on the exchange ratio of 0.3319 . EQM recognized share-based compensation expense of $0.9 million and less than $0.1 million for the year ended December 31, 2018 and for the period from November 13, 2017 through December 31, 2017, respectively. 10 .

(b) See Note 1 for a discussion of fair value measurements. $3 Billion Facility . On October 31, 2018, EQM amended and restated its credit facility to increase the borrowing capacity from $1 billion to $3 billion and extend the term to October 2023 (the $3 Billion Facility). The $3 Billion Facility is available for general partnership purposes, including to purchase assets, and to fund working capital requirements and capital expenditures, pay distributions and repurchase units. Subject to satisfaction of certain conditions, the $3 Billion Facility has an accordion feature that allows EQM to increase the available borrowings under the facility by up to an additional $750 million . The $3 Billion Facility has a sublimit of up to $250 million for same-day swing line advances and a sublimit of up to $400 million for letters of credit. In addition, EQM has the ability to request that one or more lenders make available term loans under the $3 Billion Facility, subject to the satisfaction of certain conditions. Such term loans would be secured by cash and qualifying investment grade securities. EQM's obligations under the revolving portion of the $3 Billion Facility are unsecured. EQM's debt issuer credit ratings determine the level of fees associated with its $3 Billion Facility and the interest rate charged by the counterparties on amounts borrowed against the lines of credit. EQM's debt credit rating and level of fees and interest rates are inversely related. Under the terms of the $3 Billion Facility, EQM can obtain Base Rate Loans (as defined in the $3 Billion Facility) or Fixed Period Eurodollar Rate Loans (as defined in the $3 Billion Facility) (Eurodollar Rate Loans). Base Rate Loans are denominated in dollars and bear interest at a base rate plus a margin of 0.125% to 0.875% determined on the basis of EQM's then current credit rating. Eurodollar Rate Loans bear interest at a Eurodollar Rate (as defined in the $3 Billion Facility) plus a margin of 1.125% to 1.875% determined on the basis of EQM's then current credit rating. EQM may voluntarily prepay its borrowings, in whole or in part, without premium or penalty, but subject to reimbursement of funding losses with respect to prepayment of Eurodollar Rate Loans. The $3 Billion Facility contains negative covenants that, among other things, limit restricted payments, the incurrence of debt, dispositions; mergers and fundamental changes; and transactions with affiliates. In addition, the $3 Billion Facility contains events of default such as insolvency, nonpayment of scheduled principal or interest obligations, change of control and cross-default related to the acceleration or default of certain other financial obligations. Under the $3 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). During the years ended December 31, 2018, 2017 and 2016, the maximum outstanding borrowings under the $3 Billion Facility were $674 million , $260 million and $401 million , respectively, the average daily balances were approximately $230 million , $74 million and $77 million , respectively, and the weighted average annual interest rates were 3.6% , 2.8% and 2.0% , 99 Table of Contents respectively. EQM had $1 million and zero letters of credit outstanding under the $3 Billion Facility as of December 31, 2018 and 2017 . For the years ended December 31, 2018 , 2017 and 2016 , commitment fees of $2.8 million , $1.8 million and $1.6 million , respectively, were paid to maintain credit availability under the credit facility. 364 -Day Facility . In the Predecessor period, EQM had a $500 million , 364 -day, uncommitted revolving loan agreement with EQT (the 364-Day Facility). Interest accrued on outstanding borrowings at an interest rate equal to the rate then applicable to similar loans under the revolving credit agreement with the largest aggregate commitment amount to which EQM was then a party, less the sum of (i) the then applicable commitment fee under such agreement and (ii) 10 basis points. EQM had no borrowings outstanding under the 364 -Day Facility as of December 31, 2018 and 2017. There were no borrowings outstanding at any time during the year ended December 31, 2018 on the 364 -Day Facility. During the year ended December 31, 2017 , the maximum outstanding borrowing under the 364 -Day Facility was $100 million , the average daily balance was approximately $23 million and the weighted average annual interest rate was 2.2% . There were no amounts outstanding at any time under the 364 -Day Facility in 2016. On November 12, 2018, in connection with the Separation, EQT terminated the EQM 364 -Day Facility. EQM Term Loan Facility . On April 25, 2018, EQM entered into a $2.5 billion unsecured multi-draw 364 -day term loan facility (the EQM Term Loan Facility). The EQM Term Loan Facility was used to fund the cash consideration for the Drop-Down Transaction, to repay borrowings under EQM’s then-existing revolving credit facility and for other general partnership purposes. In connection with EQM's issuance of the 2018 Senior Notes (defined below), on June 25, 2018, the outstanding balance under the EQM Term Loan Facility was repaid and the EQM Term Loan Facility was terminated. As a result of the termination, EQM expensed $3 million of deferred issuance costs. Under the EQM Term Loan Facility, from April 25, 2018 through June 25, 2018, the maximum outstanding borrowing was $1,825 million , the average daily balance was approximately $1,231 million , and the weighted average annual interest rate was 3.3% . RMP $850 Million Facility . RM Operating LLC (formerly known as Rice Midstream OpCo LLC) (Rice Midstream OpCo), a wholly owned subsidiary of RMP, had an $850 million credit facility. The RMP $850 Million Facility was available for general partnership purposes, including to purchase assets, and to fund working capital requirements and capital expenditures, pay dividends and repurchase units. The RMP $850 Million Facility was secured by mortgages and other security interests on substantially all of RMP's properties and was guaranteed by RMP and its restricted subsidiaries. As of December 31, 2017, Rice Midstream OpCo had $286 million of borrowings and $1 million of letters of credit outstanding under the RMP $850 Million Facility. For the period from January 1, 2018 through July 23, 2018, the maximum amount of RMP's outstanding borrowings under the RMP $850 Million Facility at any time was $375 million and the average daily outstanding balance under the RMP $850 Million Facility was approximately $300 million . Interest was incurred on the RMP $850 Million Facility at weighted average annual interest rates of 3.8% for the period from January 1, 2018 through July 23, 2018, respectively. In connection with the completion of the EQM-RMP Merger, on July 23, 2018, EQM repaid the approximately $260 million of borrowings outstanding under the RMP $850 Million Facility and the RMP $850 Million Facility was terminated. 2014 Senior Notes . During the third quarter of 2014, EQM issued $500 million aggregate principal amount of 4.00% senior notes due August 1, 2024 (the 4.00% Senior Notes). EQM used the net proceeds from the offering to repay the outstanding borrowings under the EQM Credit Facility and for general partnership purposes. EQM's senior notes contain covenants that limit EQM's ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of EQM's assets. 2016 Senior Notes . During the fourth quarter of 2016, EQM issued 4.125% Senior Notes due December 1, 2026 in the aggregate principal amount of $500 million . Net proceeds from the offering were used to repay the outstanding borrowings under the predecessor facility to the $3 Billion Facility at that time and for general partnership purposes. EQM's senior notes contain covenants that limit EQM's ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of EQM's assets. 2018 Senior Notes . In June 2018, EQM issued 4.75% senior notes due July 15, 2023 in the aggregate principal amount of $1.1 billion , 5.50% senior notes due July 15, 2028 in the aggregate principal amount of $850 million and 6.50% senior notes due July 15, 2048 in the aggregate principal amount of $550 million (collectively, the 2018 Senior Notes). EQM received net proceeds from the offering of $2,465.8 million , inclusive of a discount of $11.8 million and estimated debt issuance costs of $22.4 million . The net proceeds were used to repay the outstanding balances under the EQM Term Loan Facility and the RMP 100 Table of Contents $850 Million Facility, and the remainder was used for general partnership purposes. The 2018 Senior Notes were issued pursuant to new supplemental indentures to EQM's existing indenture dated August 1, 2014. The 2018 Senior Notes contain covenants that limit EQM's ability to, among other things, incur certain liens securing indebtedness, engage in certain sale and leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all of EQM's assets. As of December 31, 2018 , EQM was in compliance with all debt provisions and covenants. 11 . Regulatory Assets and Liabilities Regulatory assets and regulatory liabilities are recoverable or reimbursable over various periods and do not earn a return on investment. EQM believes that it will continue to be subject to rate regulation that will provide for the recovery or reimbursement of its regulatory assets and regulatory liabilities. Regulatory assets and regulatory liabilities are included in other assets and other long-term liabilities, respectively, in the accompanying consolidated balance sheets. Regulatory assets: Deferred taxes (a) Other recoverable costs (b) Total regulatory assets Regulatory liabilities: Deferred taxes (a) On-going post-retirement benefits other than pensions (c) Other reimbursable costs Total regulatory liabilities As of December 31, 2018 2017 (Thousands) $ $ $ $ 12,232 $ 4,312 16,544 $ 10,119 $ 10,132 1,082 21,333 $ 13,076 4,754 17,830 10,488 7,724 860 19,072 (a) The regulatory asset for deferred taxes primarily related to deferred income taxes recoverable through future rates on a historical deferred tax position and the equity component of AFUDC. The regulatory liability for deferred taxes relates to a revaluation of the historical difference between the regulatory and tax bases of regulated property, plant and equipment. EQM expects to recover the amortization of the deferred tax positions ratably over the corresponding life of the underlying assets that created the differences. Taxes on the equity component of AFUDC and the offsetting deferred income taxes will be collected through rates over the depreciable lives of the long-lived assets to which they relate. (b) Regulatory assets associated with other recoverable costs primarily related to the costs associated with the pension termination discussed in Note 15 . (c) EQM defers expenses for on-going post-retirement benefits other than pensions which are subject to recovery in approved rates. The regulatory liability reflects lower cumulative actuarial expenses than the amounts recovered through rates. 12 . Income Taxes As a result of its limited partnership structure, EQM 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 EQM flow through to EQM's unitholders; accordingly, EQM does not record a provision for income taxes. As discussed in Note 2 , the October 2016 Acquisition was a transaction between entities under common control for which the consolidated financial statements of EQM have been retrospectively recast to reflect the combined entities. Accordingly, the income tax effect associated with the operations prior to acquisition are reflected in the consolidated financial statements as it was previously part of EQT's consolidated federal tax return. EQT's consolidated federal income tax was allocated among the group's members on a separate return basis with tax credits allocated to the members generating the credits. During the year ended December 31, 2016, net current and deferred income tax liabilities of approximately $94.0 million were eliminated through equity related to AVC, Rager and the Gathering Assets. 101 Table of Contents The components of income tax expense for the year ended December 31, 2016 are as follows: Current: Federal State Subtotal Deferred: Federal State Subtotal Total (Thousands) $ $ 886 487 1,373 8,302 472 8,774 10,147 Income tax expense for the year ended December 31, 2016 differed from amounts computed at the federal statutory rate of 35% on pre-tax book income from continuing operations as follows: Tax at statutory rate Partnership income not subject to income taxes State income taxes Regulatory assets Other Income tax expense (benefit) Effective tax rate $ (Thousands) 191,835 (182,455) 623 132 12 $ 10,147 1.9% EQM's historical uncertain tax position related to the October 2016 Acquisition was immaterial. EQT has indemnified EQM from and against any losses suffered or incurred by EQM and related to or arising out of or in connection with any federal, state or local income tax liabilities attributable to the ownership or operation of EQM's assets prior to the acquisition of such assets from EQT. Therefore, EQM does not anticipate any future liabilities arising from the historical deferred tax liabilities. 13 . Concentrations of Credit Risk For the years ended December 31, 2018 , 2017 and 2016 , EQT accounted for approximately 74% , 74% and 75% , respectively, of EQM's total revenues across all of its operating segments. Additionally, for the years ended December 31, 2018 , 2017 and 2016 , PNG Companies LLC and its affiliates accounted for approximately 7% , 11% and 12% , respectively, of EQM's total revenues. As of December 31, 2018 and 2017, approximately 51% and 39% , respectively, of the accounts receivable balances represented amounts due from marketers excluding EQT. To manage the credit risk related to transactions with marketers, EQM engages with only those that meet specified criteria for credit and liquidity strength and actively monitors accounts with marketers. In connection with its assessment of marketer credit and liquidity strength, EQM may request a letter of credit, guarantee, performance bond or other credit enhancement. EQM did not experience significant defaults on accounts receivable during the years ended December 31, 2018 , 2017 and 2016 . 14 . Commitments and Contingencies In the ordinary course of business, various legal and regulatory claims and proceedings are pending or threatened against EQM and its subsidiaries. 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 incurred. EQM establishes reserves whenever it believes it to be appropriate for pending matters. Furthermore, after consultation with counsel and considering available insurance, EQM believes that the ultimate outcome of any matter currently pending against EQM will not materially affect its business, financial condition, results of operations, liquidity or ability to make quarterly cash distributions to EQM unitholders, including Equitrans Midstream. EQM is subject to federal, state and local environmental laws and regulations. These laws and regulations, which are constantly changing, can require expenditures for remediation and, in certain instances, can result in assessment of fines. EQM has established procedures for the ongoing evaluation of its operations to identify potential environmental exposures and to ensure 102 Table of Contents compliance with regulatory requirements. The estimated costs associated with identified situations requiring remedial action are accrued; however, when recoverable through future regulated rates, certain of these costs are deferred as regulatory assets. Ongoing expenditures for compliance with environmental laws and regulations, including investments in facilities to meet environmental requirements, have not been material. Management believes that any such required expenditures will not be significantly different in either nature or amount in the future and does not know of any environmental liabilities that will have a material effect on EQM's business, financial condition, results of operations, liquidity or ability to make quarterly cash distributions to EQM's unitholders. EQM has identified situations that require remedial action for which approximately $2.1 million is included in other liabilities and credits in the consolidated balance sheets as of December 31, 2018. EQM has a water system expansion and supply agreement with Southwestern Pennsylvania Water Authority (SPWA) (SPWA Agreement), pursuant to which EQM agreed to fund and assist SPWA in its construction and expansion of a water supply system that serves parts of Greene, Fayette and Washington Counties in Pennsylvania. In exchange, SPWA granted EQM preferred rights to water volumes supplied through the system for use in EQM's business. EQM is also entitled to a surcharge of $3.50 per 1,000 gallons of water sold assessed by SPWA against customers that use the system. All facilities and improvements that are constructed pursuant to the SPWA Agreement are the property of SPWA. To date, EQM authorized expenditures of approximately $29.5 million and funded expenditures of $13.4 million and $11.7 million during the years ended December 31, 2018 and 2017, respectively. As of December 31, 2018, EQM had a remaining commitment of approximately $0.8 million associated with these authorizations. See Note 7 for discussion of the MVP Joint Venture guarantees. 15 . Post-retirement Benefit Plans Prior to the Separation, employees of EQT operated EQM's assets. EQT charged EQM for the payroll and benefit costs associated with these individuals and for retirees of Equitrans, the owner of EQM's FERC-regulated transmission, storage and gathering systems. Post-Separation, employees of Equitrans Midstream operate EQM's assets. Equitrans Midstream charges EQM for the payroll and benefit costs associated with these individuals and for the retirees of Equitrans. Equitrans Midstream carries obligations for employee-related benefits in its financial statements. In 2014, EQT terminated the Retirement Plan. Prior to its termination, the retirees of Equitrans participated in the Retirement Plan. On March 2, 2016, the IRS issued a favorable determination letter for the termination of the Retirement Plan. On June 28, 2016, EQT purchased annuities from, and transferred the Retirement Plan assets and liabilities to, American General Life Insurance Company. In the third quarter of 2016, EQM reimbursed EQT $5.2 million for its proportionate share of the funding related to the retirees of Equitrans. The settlement charge is expected to be recoverable in FERC-approved rates and, thus, was recorded as a regulatory asset that will be amortized for rate recovery purposes over a period of 16 years. Excluding the Retirement Plan termination settlement described above, for the year ended December 31, 2016, EQM reimbursed EQT $1.9 million for the funding of the Retirement Plan and was allocated expenses associated with the Retirement Plan of $0.1 million . In the Predecessor period, EQM contributed to a defined contribution plan sponsored by EQT. The contribution amount was equal to a percentage of allocated base salary and EQM was charged its contribution percentage through the EQT payroll and benefit costs discussed in Note 6 . In the Successor period, Equitrans Midstream is the plan sponsor to EQM's defined contribution plan. EQM recognizes expenses for ongoing post-retirement benefits other than pensions, which are subject to recovery in FERC-approved rates. Expenses recognized by EQM for ongoing post-retirement benefits other than pensions were approximately $1.2 million for each year ended December 2018, 2017 and 2016. 103 Table of Contents 16 .

Controls and Procedures Evaluation of Disclosure Controls and Procedures Under the supervision and with the participation of management of the EQM General Partner, including the EQM General Partner's Principal Executive Officer and Principal Financial Officer, an evaluation of EQM'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 EQM General Partner concluded that EQM'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 fourth quarter of 2018 that have materially affected, or are reasonably likely to materially affect, EQM's internal control over financial reporting. 104 Table of Contents Management's Report on Internal Control over Financial Reporting The management of the EQM General Partner is responsible for establishing and maintaining adequate internal control over financial reporting. EQM's internal control system is designed to provide reasonable assurance to the management and Board of Directors of the EQM General Partner regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. All internal control systems, no matter how well designed, have inherent limitations. Accordingly, even effective controls can provide only reasonable assurance with respect to financial statement preparation and presentation. The management of the EQM General Partner assessed the effectiveness of EQM's internal control over financial reporting as of December 31, 2018 . In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control- Integrated Framework (2013) . Based on this assessment, management concluded that EQM maintained effective internal control over financial reporting as of December 31, 2018 . Ernst & Young LLP (Ernst & Young), the independent registered public accounting firm that audited EQM's consolidated financial statements, has issued an attestation report on EQM's internal control over financial reporting. Ernst & Young's attestation report on EQM's internal control over financial reporting appears in Part II, Item 8 of this Annual Report on Form 10-K and is incorporated by reference herein. Item 9B.

Item 10. Directors, Executive Officers and Corporate Governance Directors and Executive Officers of EQM's General Partner EQM is managed and operated by the directors and officers of the EQM General Partner. Through its ownership and control of the EQM General Partner, Equitrans Midstream appoints the directors of the EQM General Partner. Unitholders are not entitled to elect the directors of the EQM General Partner or directly or indirectly participate in EQM’s management or operations. The Board of Directors of the EQM General Partner (Board) has seven directors, of which three members are independent as defined under the independence standards established by the NYSE and the Exchange Act. The NYSE does not require a publicly traded limited partnership like EQM to have a majority of independent directors on the board of directors of its general partner or to establish a compensation or a nominating and corporate governance committee. Executive officers of the EQM General Partner manage the day-to-day affairs of EQM’s business and conduct EQM’s operations. All of the executive officers of the EQM General Partner are employees of Equitrans Midstream and devote such portion of their productive time to EQM’s business and affairs as is required to manage and conduct EQM’s operations. Pursuant to the terms of the omnibus agreement among EQM, the EQM General Partner and Equitrans Midstream, EQM is required to reimburse Equitrans Midstream for (i) allocated expenses of personnel who perform services for EQM’s benefit, and (ii) allocated general and administrative expenses.

The presiding director may be contacted by mail or courier service c/o EQM Midstream Services, LLC, 625 Liberty Avenue, Suite 2000, Pittsburgh, Pennsylvania 15222, Attn: Presiding Director or by email at EQMPresidingDirector@equitransmidstream.com. Committees of the Board of Directors The Board has two standing committees: an Audit Committee and a Conflicts Committee. The NYSE does not require a publicly traded limited partnership like EQM to have a majority of independent directors on the board of directors of its general partner or to establish a compensation or a nominating and corporate governance committee. Audit Committee The EQM General Partner is required by the NYSE to have an Audit Committee of at least three members and all of the Audit Committee members must meet the independence and experience requirements established by the NYSE and the Exchange Act. The Audit Committee consists of Messrs. Bryson (Chair) and Burke and Ms. Washington. Each member of the Audit Committee satisfies the independence requirements established by the NYSE and the Exchange Act and is financially literate. Additionally, the Board has determined that each member of the Audit Committee qualifies as an “audit committee financial expert” as such term is defined under the SEC’s regulations. This designation is a disclosure requirement of the SEC related to each Audit Committee member’s experience and understanding with respect to certain accounting and auditing matters. The designation does not impose upon the Audit Committee members any duties, obligations or liabilities that are greater than those 108 Table of Contents generally imposed on them as members of the Audit Committee and the Board. As audit committee financial experts, each member of the Audit Committee also has the accounting or related financial management expertise required by the NYSE rules. The Audit Committee assists the Board in its oversight of the integrity of EQM’s financial statements and compliance with legal and regulatory requirements and corporate controls. The Audit Committee has the sole authority to retain and terminate EQM’s independent registered public accounting firm, approve all auditing services and related fees and the terms thereof, and pre-approve any non-audit services to be rendered by EQM’s independent registered public accounting firm. The Audit Committee is also responsible for confirming the independence and qualifications of EQM’s independent registered public accounting firm. Conflicts Committee The Conflicts Committee consists of Ms. Washington (Chair) and Mr. Bryson. The Conflicts Committee, upon request by the EQM General Partner, determines whether certain transactions, which may be deemed conflicts of interest, are in the best interests of EQM and its unitholders. EQM’s partnership agreement does not require that the EQM General Partner seek the approval of the Conflicts Committee for the resolution of any conflict. The members of the Conflicts Committee may not be officers or employees of the EQM General Partner or directors, officers or employees of its affiliates, may not hold an ownership interest in the EQM General Partner or its affiliates other than EQM common units or awards under any long-term incentive plan, equity compensation plan or similar plan implemented by the EQM General Partner or EQM, and must meet the independence standards established by the NYSE and the Exchange Act to serve on the Audit Committee. Any matters approved by the Conflicts Committee in good faith will be deemed to be approved by all of EQM’s partners and not a breach by the EQM General Partner of any duties it may owe EQM or its unitholders. Any unitholder challenging any matter approved by the Conflicts Committee will have the burden of proving that the members of the Conflicts Committee did not subjectively believe that the matter was in the best interests of EQM. Moreover, any acts taken or omitted to be taken in reliance upon the advice or opinions of experts such as legal counsel, accountants, appraisers, management consultants and investment bankers, where the EQM General Partner (or any members of the Board including any member of the Conflicts Committee) reasonably believes the advice or opinion to be within such person’s professional or expert competence, shall be conclusively presumed to have been done or omitted in good faith. Governance Principles EQM has adopted a code of business conduct and ethics applicable to all directors, officers, employees, and other personnel of EQM and its subsidiaries, as well as EQM’s suppliers, vendors, agents, contractors and consultants. The code of business conduct and ethics, along with EQM’s corporate governance guidelines and Audit Committee charter, are posted on EQM’s website, www.eqm-midstreampartners.com (accessible under the “Governance” caption of the “Investors” page), and a printed copy of any of these documents will be delivered free of charge on request by writing to the Corporate Secretary of the EQM General Partner by mail or courier service c/o EQM Midstream Services, LLC, 625 Liberty Avenue, Suite 2000, Pittsburgh, Pennsylvania 15222, Attn: Corporate Secretary. EQM intends to satisfy the disclosure requirement regarding certain amendments to, or waivers from, provisions of its code of business conduct and ethics by posting such information on EQM’s website. Section 16(a) Beneficial Ownership Reporting Compliance Section 16(a) of the Exchange Act requires that the directors and executive officers of the EQM General Partner and all persons who beneficially own more than 10% of EQM’s common units file initial reports of ownership and reports of changes in ownership of EQM’s common units with the SEC. As a practical matter, EQM assists the directors and executive officers of the EQM General Partner by monitoring transactions and completing and filing Section 16 reports on their behalf. Based solely upon EQM’s review of copies of filings or written representations from the reporting persons, EQM believes that all reports for the executive officers and directors of the EQM General Partner and persons who beneficially own more than 10% of EQM’s common units that were required to be filed under Section 16(a) of the Exchange Act in 2018 were filed on a timely basis, except that on February 26, 2018 Messrs. Bott and Bryson and Ms. Washington each filed a late Form 4 related to distribution equivalent rights earned under the EQT Midstream Services, LLC 2012 Long-Term Incentive Plan as part of prior awards of Phantom Units. The filing was not made on a timely basis due to an administrative error by the EQM General Partner . 109 Table of Contents Item 11. Executive Compensation COMPENSATION DISCUSSION AND ANALYSIS EQM does not directly employ any of the persons responsible for managing its business. EQM is managed and operated by the directors and officers of the EQM General Partner. Equitrans Midstream employs and compensates all of the individuals who service EQM, including the executive officers of the EQM General Partner, and these individuals devote such portion of their productive time to EQM’s business and affairs as is required to manage and conduct EQM’s operations. EQM reimburses Equitrans Midstream for salaries, long- and short-term incentives and related benefits and expenses for the employees of Equitrans Midstream who provide services to EQM pursuant to the terms of the ETRN Omnibus Agreement. Prior to the Separation, EQM reimbursed EQT for such items under the terms of an omnibus agreement terminated in connection with the Separation. Please see Item 13, “Certain Relationships and Related Transactions, and Director Independence — Agreements with Equitrans Midstream — Omnibus Agreement” and “Certain Relationships and Related Transactions, and Director Independence - Agreements with EQT — Omnibus Agreement.” This Compensation Discussion and Analysis describes the objectives, principles and components of, prior to the Separation, EQT’s, and following the Separation, Equitrans Midstream’s, compensation program as well as the material elements of compensation for the EQM General Partner’s named executive officers. For 2018, the executive officers of the EQM General Partner discussed below as the EQM General Partner named executive officers are: • • • • • • • • Thomas F. Karam, Chairman, President and Chief Executive Officer; Kirk R. Oliver, Senior Vice President and Chief Financial Officer; Diana M. Charletta, Executive Vice President and Chief Operating Officer; Phillip D. Swisher, Vice President and Chief Accounting Officer; Steven T. Schlotterbeck, Former President and Chief Executive Officer; Robert J. McNally, Former Senior Vice President and Chief Financial Officer; Jeremiah J. Ashcroft, III, Former President and Chief Executive Officer and Former Senior Vice President and Chief Operating Officer; and Jimmi Sue Smith, Former Chief Accounting Officer. The EQM General Partner’s named executive officers serving at the end of 2018, Messrs. Karam, Oliver and Swisher and Ms. Charletta, are also executive officers of Equitrans Midstream. The EQM General Partner’s named executive officers covered by this discussion but no longer serving at the end of 2018 were or are executive officers of EQT. Mr. Schlotterbeck and Mr. Ashcroft were executive officers of EQT for portions of 2018 and Mr. McNally and Ms. Smith are current executive officers of EQT. Neither EQM nor the EQM General Partner has a compensation committee. Effective as of the Separation, all decisions as to the compensation of the executive officers of the EQM General Partner are made by the Management Development and Compensation Committee of the Board of Directors of Equitrans Midstream (the ETRN MDC Committee). All decisions prior to the Separation, including decisions for former executive officers of the EQM General Partner, were made by the Management Development and Compensation Committee of EQT (the EQT MDC Committee). Therefore, neither EQM nor the EQM General Partner has any policies or programs relating to compensation, and neither EQM nor the EQM General Partner make decisions relating to compensation, though from time to time the Board of Directors of the EQM General Partner may be asked to approve awards granted under the EQT Midstream Services, LLC 2012 Long-Term Incentive Plan. The EQM General Partner expects any such future awards to be pre-approved by the ETRN MDC Committee as part of the executive’s total Equitrans Midstream compensation. None of the executive officers of the EQM General Partner have employment agreements with the EQM General Partner or EQM or are otherwise specifically compensated for their service as an executive officer of the EQM General Partner. A discussion of Equitrans Midstream’s compensation policies and programs as they apply to Equitrans Midstream’s named executive officers, including Messrs. Karam, Oliver and Swisher and Ms. Charletta, will be included in Equitrans Midstream’s Disclosure Document.

Executive Pay Components Base Salary In 2018 prior to the Separation, EQT set the base salary for Messrs. Karam, Oliver and Swisher and Ms. Charletta. Following the Separation, the ETRN MDC Committee approved the base salaries set forth below for each of the EQM General Partner’s named executive officers who are executive officers of Equitrans Midstream, effective as of November 17, 2018: Name Title Thomas F. Karam Kirk R. Oliver Diana M. Charletta Phillip D. Swisher President and Chief Executive Officer Senior Vice President and Chief Financial Officer Executive Vice President and Chief Operating Officer Vice President and Chief Accounting Officer Base Salary $675,000 $500,000 $400,000 $224,000 The ETRN MDC Committee anticipates that base salaries will be considered and, where appropriate, ordinarily adjusted towards the beginning of each calendar year. Annual Incentives In connection with the Separation, and pursuant to the Employee Matters Agreement, dated as of November 12, 2018, between Equitrans Midstream and EQT (the Employee Matters Agreement), the short-term incentive awards previously granted to Equitrans Midstream’s employees pursuant to the EQT short-term incentive compensation plans (including the underlying performance goals) remained in place for 2018. The EQT performance metrics included the following: For Equitrans Midstream’s named executive officers other than Mr. Karam, the ETRN MDC Committee and Mr. Karam conducted a review of each executive officer’s performance. Mr. Karam also provided a self-assessment to the ETRN MDC Committee to 111 Table of Contents assist its review of his performance. Based on these reviews, the successful planning and execution of the Separation, and the significant additional executive team performance highlights outlined in the table below, the ETRN MDC Committee determined it was appropriate to increase the aggregate annual incentive amount payable to the named executive officers by approximately $0.2 million. From this aggregate bonus amount, the ETRN MDC Committee recommended, and the Equitrans Midstream Board of Directors approved, the following specific annual bonus payments for 2018 for each executive officer who is a named executive officer of Equitrans Midstream: 2018 Annual Incentive Award Payout Thomas F. Karam Kirk R. Oliver Diana M. Charletta $267,000 $20,000 $321,040 2018 Executive Team Performance Highlights • Successful integration of Rice Energy Inc. midstream assets • Consummation of the merger of EQM Midstream Partners, LP and Rice Midstream Partners LP • Equitrans Midstream’s successful acquisition of EQGP Holdings, LP and related financing Phillip D. Swisher $151,081 • Successful execution of EQM’s $2.5 billion senior notes offering and $2 billion upsize of EQM’s revolving credit facility • Reduction of gathering unit cost rate 2% more than business plan • Achievement of 98% availability for compression equipment Long-Term Incentives 2018 EQT LTIP Grants EQT reported that in January 2018, prior to the Separation, the EQT MDC Committee awarded long-term incentives to each of Ms. Charletta and Mr. Swisher, pursuant to the EQT Corporation 2014 Long-Term Incentive Plan (the EQT LTIP). In addition, EQT reported that, in August 2018 and September 2018 prior to the Separation, the EQT MDC Committee awarded long-term incentives to Mr. Karam and Mr. Oliver respectively, pursuant to the EQT LTIP. In developing the 2018 long-term incentive program, EQT reported that the EQT MDC Committee designed a program it believed would: align the interests of the named executive officers with the interests of its shareholders, drive appropriate performance, be market competitive, promote retention, be tax efficient, minimize earnings volatility, and result in a portfolio approach to performance metrics. The table below sets forth the types and amounts of awards EQT reported were received by each named executive officer under the EQT LTIP during 2018. A detailed description of the terms of each type of award is included in the sections that follow. Name Thomas F. Karam Kirk R. Oliver Diana M. Charletta Phillip D. Swisher EQT LTIP Award Restricted Shares Restricted Stock Units SIA Restricted Stock Units IPSUP Perf. Share Units Value Driver Perf. Share Units 59,340 — — — — 8,710 2,070 550 — — — 650 — — 2,070 550 — — 4,140 1,100 Effective upon the Separation, each award under the EQT LTIP was converted into two separate awards - a post-Separation EQT award and an Equitrans Midstream award. Both the post-Separation EQT award and the Equitrans Midstream award remained subject to the same terms and conditions (including with respect to vesting) after the conversion; provided that, after the conversion, pursuant to the terms of the Employee Matters Agreement, (i) the number of shares subject to the post-Separation EQT award was equal to the number of EQT shares subject to such award immediately prior to the conversion, (ii) the number of shares subject to the Equitrans Midstream award was equal to the number of EQT shares subject to such award immediately prior to the conversion, multiplied by a distribution ratio, and (iii) service requirements may be satisfied by service with Equitrans Midstream. Restricted Share Awards The restricted shares granted by the EQT MDC Committee in August 2018 to Mr. Karam will vest on the third anniversary of the grant date thereof, contingent upon continued service with Equitrans Midstream through such date. 112 Table of Contents Restricted Stock Unit Awards The restricted stock units granted by the EQT MDC Committee to Ms. Charletta and Mr. Swisher in January 2018 will vest on January 1, 2021, contingent upon continued service with Equitrans Midstream through such date, and be payable in cash. The restricted stock units granted to Mr. Oliver in September 2018 will vest on September 10, 2021, contingent upon continued service with Equitrans Midstream through such date, and be payable in cash. IPSUP Performance Share Units EQT reported that the 2018 EQT Incentive Performance Share Unit Program (IPSUP) performance share units were designed to drive long-term value directly related to EQT production efficiency by using operating efficiency, development efficiency and return on capital employed as well as relative total shareholder return (TSR) performance as performance metrics over the period beginning January 1, 2018 and ending December 31, 2020. EQT also reported that, as a result, the performance measures and their weighting under the 2018 EQT IPSUP were based on EQT’s performance over the period January 1, 2018 through December 31, 2020, as follows: Relative TSR (50%) Operating Efficiency (25%) Development Efficiency (25%) » Measures total shareholder return relative to EQT’s 2018 peer group of companies over the performance period. » Measures the company’s efficiency in operating expenses over the performance period. » Measures the company’s efficiency in capital spending on wells SPUD and turned-in-line over the performance period. Return on Capital Employed (may modify performance on all other metrics by up to 10%) » Measures the company’s return over the performance period. Effective as of the Separation, one-third of the 2018 EQT IPSUP performance share units remained subject to and were earned based on actual performance as of December 31, 2018 with respect to the performance measures described above, subject to continued employment with Equitrans Midstream. Of the remaining two- thirds of the 2018 EQT IPSUP performance share units, the post-Separation EQT award component will be earned based on new performance goals related to EQT performance and the Equitrans Midstream award component will be earned based on new performance goals related to Equitrans Midstream performance, each for the period beginning January 1, 2019 and ending December 31, 2020. Value Driver Performance Share Units EQT reported that the 2018 EQT Value Driver (VDA) performance share units were designed to drive the focus of next tier senior leadership on activities aligned with EQT’s business plan and on EQT, business unit, and individual value drivers considered critical to EQT’s long-term success. Effective as of the Separation, the earnings before interest, taxes, depreciation and amortization (EBITDA) goal for the 2018 VDA performance share units was deemed satisfied. In addition, the satisfaction of the business unit value drivers and other applicable performance goals shall be determined based on actual performance as of the earlier of December 31, 2018 or the last date performance can be determined for the post-Separation EQT award component and as of September 30, 2018 for the Equitrans Midstream award component. One-half of the 2018 EQT VDA performance share units will be confirmed and vest upon payment in cash in the first quarter of 2019, and the remaining one-half will be confirmed and vest upon payment in cash in the first quarter of 2020, subject in each case to continued employment with Equitrans Midstream. Strategic Implementation Awards The Separation was an extraordinarily complex transaction, and EQT reported that the EQT MDC Committee determined it was important to have a stable, focused and experienced leadership team throughout this process. Accordingly, in recognition of the management team’s efforts and to incentivize future efforts, the EQT MDC Committee approved a Strategic Implementation Award (SIA) for Mr. Swisher in March 2018. The SIA for Mr. Swisher included the following components: The SIA restricted stock units vest (a) 50% on the first anniversary of the grant date and (b) 50% on the second anniversary of the grant date. Mr. Swisher received the following grants under the SIA program: 113 Table of Contents Name Phillip D. Swisher Separation of Jeremiah J. Ashcroft III Cash $16,667 RSUs 650 As noted above, Mr. Ashcroft was the Senior Vice President and Chief Operating Officer for the EQM General Partner from January 1, 2018 through March 15, 2018 and was the principal executive officer from March 16, 2018 through August 8, 2018, when his employment terminated. In 2018, prior to the Separation, EQT awarded Mr. Ashcroft 41,900 stock options, 12,550 shares of restricted stock, 25,090 performance share units under the 2018 EQT IPSUP, and $50,000 and 2,020 performance share units under a Strategic Implementation Award that would have been forfeited if the Separation had not occurred by March 15, 2020. For additional information regarding the payments Mr. Ashcroft received from EQT in connection with his termination, please see the “Payments Upon Termination of Employment or a Change of Control” below. Other Benefits Health and Welfare Benefits Following the Separation, the executive officers who are named executive officers of Equitrans Midstream participate in the same health and welfare benefit plans offered to other Equitrans Midstream employees, including medical, prescription drug, dental, vision, short- and long-term disability, wellness and employee assistance programs. The same contribution amounts, deductibles and plan design provisions are generally applicable to all employees. Retirement Program Following the Separation, the executive officers who are named executive officers of the EQM General Partner participate in the same defined contribution 401(k) plan as other Equitrans Midstream employees. Equitrans Midstream typically contributes an amount equal to 6% of each participant’s base salary to an individual investment account for the employee, subject to applicable tax regulations. In addition, Equitrans Midstream matches a participant’s elective contribution by contributing to the participant’s individual investment account an amount equal to 50% of each dollar contributed by the employee, subject to a maximum Equitrans Midstream contribution of 3% of the employee’s base salary and to applicable tax regulations. Once Equitrans Midstream contributions for Mr. Karam reached the maximum level permitted under the 401(k) plan, Equitrans Midstream contributions were continued on an after-tax basis through a retirement annuity product offered by Fidelity Investments Life Insurance Co. Under this program, Equitrans Midstream also contributed to the annuity an amount equal to 11% of Mr. Karam’s annual incentive award for 2018. The after-tax annuity program contains no vesting requirements. Limited Perquisites EQT previously offered perquisites to certain of the EQT named executive officer including the following: a car allowance, a country club and a dining club membership, executive physical (including preferred access to healthcare professionals and related services for the executive and his/her spouse), financial planning, life insurance and accidental death and disability insurance (both of which exceed the level of insurance provided to other employees), and de minimis personal usage of EQT purchased event tickets and parking. Consistent with its philosophy of pay for performance, Equitrans Midstream only provides modest perquisites to its named executive officers that, in number and value, are below median competitive levels for the peer group. See footnote (6) to the Summary Compensation Table below for a discussion of the perquisites provided to the named executive officers in 2018.

Under the EQT 2018 Executive STIP, a formula based on EQM adjusted 2018 EBITDA compared to EQT’s business plan establishes the maximum payment for EQT employees from which the EQT MDC Committee may exercise its discretion downward in determining the actual payment. The payout amounts could range from no payment, to the percentage of base salary identified as the target annual incentive award (target), to $5 million (maximum). (3) These columns reflect the target and maximum number of units payable under the EQT 2018 Incentive PSU Program and the EQT 2018 Value Driver Performance Share Unit Awards, as applicable. They also reflect the number of units payable under the EQT 2018 Strategic Implementation Awards. For all named executive officers other than Mr. Swisher, the Strategic Implementation Award would have been forfeited if the Separation had not occurred by March 15, 2020. For details of each of these programs and awards, see the relevant section under “Long-Term Incentives” in the Compensation Discussion and Analysis above. The vesting schedules of the grants mentioned in these columns are as follows for each named executive officer (subject to continued employment with EQT or Equitrans Midstream, as applicable, through each applicable vesting date): EQT 2018 IPSUP Awards Type of Award EQT 2018 Value Drive Performance Share Unit Awards EQT 2018 Strategic Implementation Awards Vesting Schedule (subject to continued employment with Equitrans Midstream) 100% vesting on the payment date following December 31, 2020 50% vesting on the payment date following December 31, 2018 50% vesting on the payment date following December 31, 2019 50% vesting on March 15, 2019 (March 7, 2019 for Mr. Swisher) 50% vesting on March 15, 2020 (March 7, 2019 for Mr. Swisher) (4) This column reflects the number of time-based restricted stock and/or share units granted to the named executive officers. For details regarding the terms of these awards, see “Restricted Shares” and "Restricted Share Units” under “Long-Term Incentives” in the Compensation Discussion and Analysis above. Each grant mentioned in this column is subject to a three year vesting schedule, subject to continued employment with EQT or Equitrans Midstream, as applicable, through the vesting date. 118 Table of Contents NARRATIVE DISCLOSURE TO SUMMARY COMPENSATION TABLE AND 2018 GRANTS OF PLAN-BASED AWARDS TABLE Confidentiality, Non-Solicitation and Non-Competition Agreements Messrs. Karam, Oliver and Swisher and Ms. Charletta have confidentiality, non-solicitation and non-competition agreements with Equitrans Midstream. In each such agreement, the named executive officer agrees, among other things, to the following restrictive covenants: • • • restrictions on competition for 24 months (12 months for Mr. Swisher); restrictions on customer solicitation for 24 months (12 months for Mr. Swisher); and restrictions on employee, consultant, vendor or independent contractor recruitment for 36 months (12 months for Mr. Swisher). In order to receive any severance benefits under his or her agreement, the named executive officer must execute and deliver to Equitrans Midstream a general release of claims. The agreements do not provide for any tax gross-ups. In the event the named executive officer would be subject to the 20% excise tax under Section 4999 of the Internal Revenue Code (imposed on individuals who receive compensation in connection with a change of control that exceeds certain specified limits), the payments and benefits to the named executive officer would be reduced to the maximum amount that does not trigger the excise tax unless the named executive officer would retain greater value (on an after-tax basis) by receiving all payments and benefits and paying all excise and income taxes. Messrs. Schlotterbeck, McNally, and Ashcroft and Ms. Smith never entered into an employment agreement with the EQM General Partner or Equitrans Midstream. The table below provides additional information regarding each outstanding Equitrans Midstream or EQT equity awards, as applicable, held by the EQM General Partner’s named executive officers as of December 31, 2018.

(2) (3) POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL Equitrans Midstream Agreements and Plans Equitrans Midstream maintains and has entered into certain agreements and plans (including those described above in “Narrative Disclosure to Summary Compensation Table and 2018 Grants of Plan-Based Awards Table”) that require Equitrans Midstream to provide compensation to the named executive officers, among others, in the event of a termination of employment or a change of control of Equitrans Midstream. Agreements with the Named Executive Officers of Equitrans Midstream Descriptions of the circumstances which trigger payments and benefits, the benefits that would be provided, how payment and benefit levels are determined and the material conditions and obligations applicable to the receipt of payments or benefits in the event of a termination of employment or a change of control of Equitrans Midstream under Equitrans Midstream’s agreements with Messrs. Karam, Oliver and Swisher and Ms. Charletta will be described in ETRN’s Disclosure Document. Equitrans Midstream’s SEC filings are available on the SEC’s website at www.sec.gov and on Equitrans Midstream’s website at www.equitransmidstream.com through the “Investors” link on the main page, followed by the “SEC Filings” page. The Corporate Secretary of the EQM General Partner will also provide a copy to you free of charge upon request. Agreements with Former Named Executive Officers Our named executive officers covered by this discussion but no longer serving at the end of 2018 were or are executive officers of EQT. Mr. Schlotterbeck and Mr. Ashcroft were executive officers of EQT prior to the termination of their employment with EQM and EQT. Mr. McNally and Ms. Smith are current executive officers of EQT who terminated service with EQM in connection with the Separation. Mr. Schlotterbeck did not receive any severance payments in connection with the termination of his employment with EQM as well as EQT. In connection with the termination of his employment with EQM as well as EQT, Mr. Aschcroft received $2,393,551.60. Mr. McNally and Ms. Smith terminated service from EQM in connection with the Separation but did not terminate service with EQT. Therefore, neither Mr. McNally nor Ms. Smith received any payments in connection with their termination as executive officers of EQM. 121 Table of Contents Pay Ratio EQM does not have any employees. The daily business operations of EQM are conducted by employees of Equitrans Midstream and its subsidiaries. Compensation of Directors Officers of ETRN who also serve as directors of the EQM General Partner do not receive additional compensation for their service as directors. During 2018, directors of the EQM General Partner who were not also officers of either EQT prior to the Separation or ETRN following the Separation received cash compensation on a quarterly basis as a board and committee retainer, other than David L. Porges, who was not an officer of ETRN, following the Separation. In addition, the Conflicts Committee members also received a meeting attendance fee. The structure of the 2018 fees is set forth below, and all fees are paid on a quarterly basis. The 2019 fees will be consistent with the 2018 fees. Compensation Feature 2018 Annual cash retainer - Board member Annual cash retainer - Committee Chair Annual cash retainer - Committee member (excluding the chair) Meeting fees $65,000 Audit: $20,000 Conflicts:$10,000 Audit: $5,000 Conflicts: None Conflicts Committee: In person: $1,500 Telephonic: $750 All other meetings: None In addition, each non-employee director is reimbursed for out-of-pocket expenses in connection with attending meetings. EQM also provides non-employee directors with $20,000 of life insurance and $250,000 of travel accident insurance while traveling on business for EQM. To further EQM’s support for charitable giving, all directors are eligible to participate in the Matching Gifts Program of the Equitrans Midstream Foundation on the same terms as ETRN employees and directors. Under this program, the Equitrans Midstream Foundation will match gifts of at least $100 made by a director to eligible charities, up to an aggregate total for each director of $50,000 in any calendar year. On an annual basis, the EQM General Partner grants to each non-employee director phantom units as a vehicle to deliver compensation for their service on the Board. On January 1, 2018, the EQM General Partner granted to each non-employee director serving at that time (Mr. Bott, Mr. Bryson and Ms. Washington) phantom units with a value of $85,000 under the EQT Midstream Services, LLC 2012 Long-Term Incentive Plan (with the number of phantom units (1,170) determined by dividing the award value by the closing price of EQM’s common units on December 29, 2017 ($73.10) and rounding up to the next ten units). Mr. Thorington, who was elected to the Board on February 26, 2018, received a pro rata portion of the $85,000 award on February 27, 2018 (with the number of phantom units (1,170) determined by dividing the pro rata award value by the closing price of EQM’s common units on February 26, 2018 ($61.10) and rounding up to the next ten units). Mr. Burke, who was elected to the Board on September 25, 2018, received a pro rata portion of the $85,000 award on September 26, 2018 (with the number of phantom units (420) determined by dividing the pro rata award value by the closing price of EQM’s common units on September 25, 2018 ($52.60) and rounding up to the next ten units). The phantom units were fully vested as of the grant date, with distribution equivalents accruing on such units. The phantom units (and the accrued distribution equivalents) will be converted into common units on the date that the grantee ceases to be a director. For 2019, the value of the annual phantom unit award remained $85,000. The table below shows the total 2018 compensation of EQM’s non-employee directors who served as a director during 2018: NAME J.M. Bott (4) M.A. Bryson K.M. Burke (4) S.A. Thorington (4) L.E.

The fourth quarter retainer and meeting fees were paid in 2019. 122 Table of Contents (2) This column reflects the aggregate grant date fair values determined in accordance with FASB ASC Topic 718 for the phantom units awarded to each director during 2018. On January 1, 2018, the EQM General Partner granted 1,170 phantom units to each non-employee director. Mr. Thorington, who was elected to the Board on February 26, 2018, received an award of 1,170 phantom units on February 27, 2018. Mr. Burke, who was elected to the Board on September 25, 2018, received an award of 420 phantom units on September 26, 2018. The grant date fair value is computed as the sum of the number of phantom units awarded on the grant date multiplied by, in the case of Messrs. Bryson and Bott and Ms. Washington, the closing price of EQM’s common units on the business day prior to the grant date, which closing price was $73.10 on December 29, 2017, in the case of Mr. Thorington, the closing price of EQM’s common units on the business day prior to the grant date, which closing price was $61.10 on February 26, 2018, and in the case of Mr. Burke, the closing price of EQM’s common units on the business day prior to the grant date, which closing price was $52.60 on September 25, 2018. (3) This column reflects (i) annual premiums of $43.88 per director paid for life insurance and travel accident insurance policies (Mr. Bott - $43.88; Mr. Bryson - $43.88; Mr. Burke - $14.63; Mr. Thorington - $14.63; and Ms. Washington - $43.88) and (ii) the following matching gifts made to qualifying organizations under the EQT Foundation’s Matching Gifts Program: Mr. Bryson - $30,000; Mr. Bott - $5,000; Mr. Thorington - $50,000; and Ms. Washington - $11,000. Prior to the Separation, the non-employee directors could use a de minimis number of tickets purchased by EQT to attend sporting or other events when such tickets were not otherwise being used for business purposes. The use of such tickets did not result in any incremental costs to EQM. (4) Mr. Bott resigned as a director on February 25, 2018; Mr. Thorington was appointed a director on February 26, 2018 and stepped down from the Board in November 2018 as of the completion of the Separation; Mr. Burke was appointed as a director on September 25, 2018. Compensation Committee Interlocks and Insider Participation As previously discussed, the Board is not required to maintain, and does not maintain, a compensation committee. Each of Messrs. Karam and Oliver, as well as Ms. Charletta, who are directors of the EQM General Partner, are also executive officers of ETRN. In addition, Mr. Cooper is also an officer of ETRN. However, all compensation decisions with respect to each of these officers are made by the ETRN MDC Committee and none of these individuals receives any compensation directly from EQM or the EQM General Partner for their service as a director. Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters Security Ownership of Certain Beneficial Owners and Management The following tables set forth the beneficial ownership of EQM's common units and ETRN's common stock owned as of January 31, 2019, by: • • • each of the directors of the EQM General Partner; each of the named executive officers of the EQM General Partner; and all directors and executive officers of the EQM General Partner as a group.

(2) The EQT Midstream Services, LLC 2012 Long-Term Incentive Plan authorizes the granting of awards in any of the following forms: phantom units, performance awards, restricted units, distribution equivalent rights, market-priced options to purchase units, unit appreciation rights, other unit-based awards that are denominated or payable in, valued in whole or in part by reference to, or otherwise based on units, and cash-based awards. EQT Midstream Services, LLC 2012 Long-Term Incentive Plan The EQM General Partner adopted the EQT Midstream Services, LLC 2012 Long-Term Incentive Plan for employees and non-employee directors of the EQM General Partner and any of its affiliates. The EQM General Partner may issue long-term equity based awards under the plan. EQM is responsible for the cost of awards granted under the plan. Employees and non-employee directors of the EQM General Partner or any affiliate, including subsidiaries, are eligible to receive awards under the plan. The aggregate number of units that may be issued under the plan is 2,000,000 units, subject to proportionate adjustment in the event of unit splits and similar events. Units underlying options and unit appreciation rights will count as one unit, and units underlying all other unit-based awards will count as two units, against the number of units available for issuance under the plan. Units subject to awards that terminate or expire unexercised, or are canceled, forfeited or lapse for any reason, and units underlying awards that are ultimately settled in cash, will again become available for future grants of awards under the plan. Units delivered by the participant or withheld from an award to satisfy tax withholding requirements, and units delivered or withheld to pay the exercise price of an option, will not be used to replenish the plan unit reserve. The plan is administered by the Board or such other committee of the Board as may be designated by the Board to administer the plan. The Board may amend, suspend or terminate the plan at any time, except that no amendment may be made without the approval of EQM’s unitholders if unitholder approval is required by any federal or state law or regulation or by the rules of any exchange on which the units may then be listed, or if the amendment, alteration or other change materially increases the benefits accruing to participants, increases the number of units available under the plan or modifies the requirements for participation under the plan, or if the Board in its discretion determines that obtaining such unitholder approval is for any reason advisable. Common units to be delivered pursuant to awards under the plan may be common units acquired by the EQM General Partner in the open market, from any other person, directly from EQM or any combination of the foregoing. When EQM issues new common units upon the grant, vesting or payment of awards under the plan, the total number of common units outstanding increases. Item 13.

EQM IDR Transaction On February 13, 2019, Equitrans Midstream entered into a definitive agreement and plan of merger with the EQM General Partner (the IDR Merger Agreement) and certain related parties, pursuant to which, among other things, Equitrans Midstream will exchange and cancel the IDRs and economic general partner interest in EQM that it holds, indirectly, for (a) 80 million newly-issued EQM common units and 7 million newly-issued Class B units (Class B units), both representing limited partner interests in EQM, and (b) the retention of a non-economic general partner interest in EQM (the EQM IDR Transaction).

The amount of any such reimbursement was limited to the tax that EQM (and its subsidiaries) would have paid had they not been included in a combined group with EQT.

Interest accrued on any outstanding borrowings at an interest rate equal to the rate then applicable to similar loans under the revolving credit agreement with the largest aggregate commitment amount to which EQM was then a party, less the sum of (i) the then applicable commitment fee under the such agreement and (ii) 10 basis points. 137 Table of Contents EQM had no borrowings outstanding on the 364 -Day Facility as of December 31, 2018 and 2017. There were no borrowing outstanding at any time during the year ended December 31, 2018 on the 364 -Day Facility. During the year ended December 31, 2017 , the maximum amount of EQM's outstanding borrowings under the 364 -Day Facility at any time was $100 million , the average daily balance was approximately $23 million and the weighted average annual interest rate was 2.2% . There were no amounts outstanding at any time under the 364 -Day Facility in 2016. On November 12, 2018, in connection with the Separation, EQT terminated the 364-Day Facility. Transmission Acreage Dedication Pursuant to an acreage dedication to EQM by EQT, EQM has the right to elect to transport, at a negotiated rate, which will be the higher of a market or cost of service rate, all natural gas produced from wells drilled by EQT on the dedicated acreage, which is an area covering approximately 60,000 acres surrounding EQM’s storage assets in Allegheny, Washington and Greene counties in Pennsylvania and Wetzel, Marion, Taylor, Tyler, Doddridge, Harrison and Lewis counties in West Virginia. The acreage dedication is contained in a sublease agreement in which EQM granted to EQT all of the oil and gas interests, including the exclusive rights to drill, explore for, produce and market such oil and gas, EQM had received as part of certain of its oil and gas leasehold estates EQM uses for gas storage and protection. Furthermore, if EQT acquires acreage with natural gas storage rights within the area of mutual interest established by the acreage dedication, then EQT will enter into an agreement with EQM to permit it to store natural gas on such acreage. Likewise, if EQM acquires acreage within the area of mutual interest with natural gas or oil production, development, marketing and exploration rights, such acreage will automatically become subject to EQT’s rights under the acreage dedication. Review, Approval or Ratification of Transactions with Related Persons The Board has adopted a related person transaction approval policy that establishes procedures for the identification, review and approval of related person transactions. Pursuant to the policy, the management of the EQM General Partner is charged with primary responsibility for determining whether, based on the facts and circumstances, a proposed transaction is a related person transaction. For purposes of the policy, a “Related Person” is any director or executive officer of the EQM General Partner, any nominee for director, any unitholder known to EQM to be the beneficial owner of more than 5% of any class of EQM’s voting securities, and any immediate family member of any such person. A “Related Person Transaction” is generally a transaction in which EQM is, or the EQM General Partner or any of its subsidiaries is, a participant, where the amount involved exceeds $120,000, and a Related Person has a direct or indirect material interest. Transactions resolved under the conflicts provision of EQM’s partnership agreement are not required to be reviewed or approved under the policy. Please read “Conflicts of Interest” below. To assist management in making this determination, the policy sets forth certain categories of transactions that are deemed to be pre-approved by the Board under the policy. The transactions which are automatically pre-approved include (i) transactions involving employment of the EQM General Partner’s executive officers, as long as the executive officer is not an immediate family member of another of the EQM General Partner’s executive officers or directors and the compensation paid to such executive officer was approved by the Board; (ii) transactions involving compensation and benefits paid to the EQM General Partner’s directors for service as a director; (iii) transactions on competitive business terms with another company in which a director or immediate family member of the director’s only relationship is as an employee or executive officer, a director, or a beneficial owner of less than 10% of that company’s shares, provided that the amount involved does not exceed the greater of $1,000,000 or 2% of the other company’s consolidated gross revenues; (iv) transactions where the interest of the Related Person arises solely from the ownership of a class of equity securities of EQM, and all holders of that class of equity securities receive the same benefit on a pro rata basis; (v) transactions where the rates or charges involved are determined by competitive bids; (vi) transactions involving the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity with law or governmental regulation; (vii) transactions involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture or similar services; and (viii) any charitable contribution, grant or endowment by EQM or any affiliated charitable foundation to a charitable or non-profit organization, foundation or university in which a Related Person’s only relationship is as an employee or a director or trustee, provided the aggregate amount involved does not exceed the greater of $1,000,000 or 2% of the recipient’s consolidated gross revenues. If, after applying these categorical standards and weighing all of the facts and circumstances, management determines that a proposed transaction is a Related Person Transaction, management must present the proposed transaction to the Board for review or, if impracticable under the circumstances, to the chairman of the Board. The Board must then either approve or reject the transaction in accordance with the terms of the policy taking into account all facts and circumstances, including (i) the benefits to EQM of the transaction; (ii) the terms of the transaction; (iii) the terms available to unaffiliated third parties and employees generally; (iv) the extent of the affected director or executive officer’s interest in the transaction; and (v) the 138 Table of Contents potential for the transaction to affect the individual’s independence or judgment. The Board may, but is not required to, seek the approval of the Conflicts Committee for the resolution of any related person transaction. Conflicts of Interest Conflicts of interest exist and may arise in the future as a result of the relationships between the EQM General Partner and its affiliates, including Equitrans Midstream, on the one hand, and EQM and its limited partners, on the other hand. The directors and officers of the EQM General Partner have duties to manage the EQM General Partner in a manner beneficial to its owners. At the same time, the EQM General Partner has a duty to manage EQM in a manner beneficial to EQM and its limited partners. The Delaware Revised Uniform Limited Partnership Act provides that Delaware limited partnerships may, in their partnership agreements, expand, restrict or eliminate the fiduciary duties otherwise owed by a general partner to limited partners and the partnership. Pursuant to these provisions, EQM’s partnership agreement contains various provisions replacing the fiduciary duties that would otherwise be owed by its general partner with contractual standards governing the duties of the general partner and the methods of resolving conflicts of interest. EQM’s partnership agreement also specifically defines the remedies available to limited partners for actions taken that, without these defined liability standards, might constitute breaches of fiduciary duty under applicable Delaware law. Four of the officers and five of the directors of the EQM General Partner are also officers and/or directors of Equitrans Midstream and owe fiduciary duties to Equitrans Midstream. Consequently, these directors and officers may encounter situations in which their obligations to Equitrans Midstream, on the one hand, and EQM, on the other hand, are in conflict. Whenever a conflict arises between the EQM General Partner or its affiliates, on the one hand, and EQM or any other partner, on the other, the EQM General Partner will resolve that conflict. The EQM General Partner may seek the approval of such resolution from the Conflicts Committee. There is no requirement that the EQM General Partner seek the approval of the Conflicts Committee for the resolution of any conflict, and, under EQM’s partnership agreement, the EQM General Partner may decide to seek such approval or resolve a conflict of interest in any other way permitted by the partnership agreement, as described below, in its sole discretion. The EQM General Partner will decide whether to refer the matter to the Conflicts Committee on a case-by-case basis. An independent third party is not required to evaluate the fairness of the resolution. The EQM General Partner will not be in breach of its obligations under the partnership agreement or its duties to EQM or its limited partners if the resolution of the conflict is: • • • • approved by the Conflicts Committee, although the EQM General Partner is under no obligation to seek such approval; approved by the vote of a majority of the outstanding common units, excluding any common units owned by the EQM General Partner or any of its affiliates; determined by the Board to be on terms no less favorable to EQM than those generally being provided to or available from unrelated third parties; or determined by the Board to be fair and reasonable to EQM, taking into account the totality of the relationships among the parties involved, including other transactions that may be particularly favorable or advantageous to EQM. The EQM General Partner may, but is not required to, seek the approval of such resolution from the Conflicts Committee. If the EQM General Partner does not seek approval from the Conflicts Committee and the Board determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in the third and fourth bullet points above, then it will be presumed that, in making its decision, the Board acted in good faith, and in any proceeding brought by or on behalf of any limited partner or EQM challenging such determination, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. In resolving conflicts of interest under the standard set forth in the fourth bullet point above, the EQM partnership agreement permits the Board to take into account the totality of the relationships among the parties involved, including other transactions that may be particularly favorable or advantageous to EQM, in determining what is fair and reasonable to EQM. Fair and reasonable is not defined in the EQM partnership agreement and what constitutes fair and reasonable will depend on the circumstances. Furthermore, the EQM partnership agreement permits the Board to consult with legal counsel, investment bankers and other advisors in making decisions, though the extent to which the Board will seek such advice will depend on the facts and circumstances of the transaction being considered. If the EQM General Partner Board reasonably believes that advice or an opinion provided by such advisors is within such person’s professional or expert competence, then any act taken in reliance upon such advice or opinion will conclusively be deemed to be fair and reasonable. Unless the resolution of a conflict is specifically provided for in EQM’s partnership agreement, the EQM General Partner or the Conflicts Committee may consider any factors it determines in good faith to consider when resolving a conflict. When EQM’s partnership agreement requires someone to act in good faith, it requires that person to 139 Table of Contents subjectively believe that he or she is acting in the best interests of EQM or meets the specified standard, for example, a transaction on terms no less favorable to EQM than those generally being provided to or available from unrelated third parties. Director Independence The NYSE does not require a listed publicly traded limited partnership, such as EQM, to have a majority of independent directors on the board of directors of its general partner. To assist it in determining the independence of the directors of the EQM General Partner, the Board established guidelines, which are included in its corporate governance guidelines and conform to the independence requirements under the NYSE listing standards. For a discussion of the independence of the Board, please see Item 10, “Directors, Executive Officers and Corporate Governance-Committees of the Board of Directors.” Item 14. Principal Accounting Fees and Services Ernst & Young LLP served as EQM’s independent auditor for the year ended December 31, 2018. The following chart details the fees billed to EQM by Ernst & Young LLP during 2018 and 2017: Audit fees (1) Audit-related fees (2) Tax fees All other fees Total Years Ended December 31, 2018 2017 817,920 $ — — — 817,920 $ 705,000 4,500 — — 709,500 $ $ (1) Includes fees for the audit of EQM’s annual financial statements and internal control over financial reporting, reviews of financial statements included in EQM’s quarterly reports on Form 10-Q, and services that are normally provided in connection with statutory and regulatory filings or engagements, including certain attest engagements, comfort letter procedures and consents. (2) Includes fees for services associated with attest engagements not required by statute or regulation. The Audit Committee of the EQM General Partner has adopted a policy regarding the services of its independent auditors under which EQM’s independent accounting firm is not allowed to perform any service that may have the effect of jeopardizing the independent public accountant’s independence. Without limiting the foregoing, the independent accounting firm shall not be retained to perform the following: • • • • • Bookkeeping or other services related to the accounting records or financial statements Financial information systems design and implementation Appraisal or valuation services, fairness opinions or contribution-in-kind reports Actuarial services Internal audit outsourcing services • Management functions • • • • • Human resources functions Broker-dealer, investment adviser or investment banking services Legal services Expert services unrelated to the audit Prohibited tax services All audit and permitted non-audit services must be pre-approved by the Audit Committee. The Audit Committee has delegated specific pre-approval authority with respect to audit and permitted non-audit services to the Chairman of the Audit Committee but only where pre-approval is required to be acted upon prior to the next Audit Committee meeting and where the aggregate audit and permitted non-audit services fees are not more than $75,000. The Audit Committee encourages management to seek 140 Table of Contents pre-approval from the Audit Committee at its regularly scheduled meetings. In 2018, 100% of the professional fees reported as audit-related fees were pre- approved pursuant to the above policy. The Audit Committee has approved the appointment of Ernst & Young LLP as EQM’s independent auditor to conduct the audit of EQM’s consolidated financial statements for the year ended December 31, 2019.
