Summary Risk Factors

Customer Concentration

Because substantially all of our revenue is currently derived from Antero Resources, any development that materially and adversely affects Antero Resources’ operations, financial condition or market reputation could have a material and adverse impact on us.
Because of the natural decline in production from existing wells, our success depends, in part, on Antero Resources’ ability to replace declining production and our ability to secure new sources of natural gas from Antero Resources or third parties. Additionally, our water handling services are directly associated with Antero Resources’ well completion activities and water needs, which are largely driven by the amount of water used in completing each well. Finally, under certain circumstances, Antero Resources may dispose of acreage dedicated to us free from such dedication without our consent. Any decrease in volumes of natural gas that Antero Resources produces, any decrease in the number of wells that Antero Resources completes, or any decrease in the number of acres that are dedicated to us could adversely affect our business and operating results.

Business Operations

A material shut-in of production by Antero Resources or any of our other customers could adversely affect our business.
The gathering and compression agreement includes minimum volume commitments only under certain circumstances.
Our construction or purchase of new gathering and compression, processing, water handling or other assets may not be completed on schedule, at the budgeted cost or at all, may not operate as designed or at the expected levels, may not result in revenue increases and may be subject to regulatory, environmental, political, legal and economic risks, all of which could adversely affect our financial condition, cash flows and results of operations.
Recent action and the possibility of future action on trade by U.S. and foreign governments has increased the costs of certain equipment and materials used in the construction of our assets and has created uncertainty in global markets, which may adversely affect our income from operations and cash flows.
If third-party pipelines or other midstream facilities interconnected to our gathering and compression systems become partially or fully unavailable, our operating margin and cash flows could be adversely affected.
Our exposure to commodity price risk may change over time.
The fees charged to our customers may not escalate sufficiently to cover increases in costs, or the agreements may be amended with less favorable terms, may not be renewed or may be suspended in some circumstances.
Oil and natural gas producers’ operations, especially those using hydraulic fracturing, are substantially dependent on the availability of water. Restrictions on the ability to obtain water may incentivize water recycling efforts by oil and natural gas producers, which would decrease the demand for our fresh water delivery services.

3ii


Table of Contents

Increasing attention to environmental, social and governance (“ESG”) matters and conversation measures may adversely impact our business.
Our business involves many hazards and operational risks, some of which may not be fully covered by insurance. The occurrence of a significant accident or other event that is not fully insured could curtail our operations and have a material adverse effect on our business, financial condition and results of operations.
A pandemic, epidemic or outbreak of an infectious disease, such as COVID-19, may materially adversely affect our business.

Capital Structure and Access to Capital

We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our indebtedness or to refinance, which may not be successful.
We will be required to make capital expenditures to increase our asset base. If we cannot obtain needed capital or financing on satisfactory terms, we may be unable to expand our business operations and/or our financial leverage could increase.
Restrictions in our existing and future debt agreements could adversely affect our business, financial condition and results of operations.

Acquisitions and Takeovers

We may be unable to make attractive acquisitions or successfully integrate acquired businesses, and any inability to do so may disrupt our business and hinder our ability to grow.
Certain of our stockholders have investments in our affiliates that may conflict with the interests of other stockholders.

Joint Ventures

We own a 50% interest in the Joint Venture, which is operated by MarkWest. While we have the ability to influence certain business decisions affecting the Joint Venture, the success of our investment in the Joint Venture will depend on MarkWest’s operation of the Joint Venture.
If the Joint Venture is not successful or if the Joint Venture does not perform as expected, our future financial performance may be negatively impacted.

Compliance with Regulations

We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities.
If our assets become subject to FERC regulation or federal, state or local regulations or policies change, or if we fail to comply with market behavior rules, our financial condition, cash flows and results of operations could be materially and adversely affected.
Increased regulation of hydraulic fracturing could result in reductions or delays in production by our customers, which could reduce the throughput on our gathering and processing systems and the number of wells for which we provide water handling services, which could adversely impact our revenues.

Related Parties

Antero Resources owns a significant interest in us and, as a result, conflicts of interest will arise from time to time between it and us, and Antero Resources may favor their own interests to the detriment of us and our other stockholders. Additionally, Antero Resources is under no obligation to adopt a business strategy that favors us.

dedicated areas.  The gathering and compression agreement expires in 2038, and the water services agreement expires in 2035.  Both agreements are underpinned by long-term agreements subject to automatic annual renewal afterwith rights by either party to terminate on or before the initial term.180th day prior to the anniversary of such effective date.

In connection with our entrance into the water services agreement, we agreed to pay Antero Resources (a) $125 million in cash if we delivered 176 million barrels or more of fresh water during the period between January 1, 2017 and December 31, 2019 and (b) an additional $125 million in cash if we delivered 219 million barrels or more of fresh water during the period between January 1, 2018 and December 31, 2020. As of December 31, 2019, we had delivered 176 million barrels of fresh water, which entitled Antero Resources to $125 million pursuant to clause (a) above. In January 2020, Antero Midstream Partners paid Antero Resources $125 million. In the three-year period ended December 31, 2020, we delivered 163 million of the 219 million barrels of fresh water, and therefore, no such payment is due to Antero Resources’ pursuant to clause (b) above. As of December 31, 2020, no additional contingent acquisition consideration is expected to be earned.

Due to the extensive geographic distribution of our water pipeline systems in both West Virginia and Ohio, we are able to provide, and have in the past provided, water delivery services to other oil and gas producers operating within and adjacent to Antero Resources’ operating area in an effort to further leverage the use of our existing system.

Operating Segments

Our operations are located in the United States and are organized into two reporting segments: (1) gathering and processing and (2) water handling. Financial information for our reporting segments is located under Note 17—Reporting Segments to our consolidated financial statements.

2020 Capital Investments

For the year ended December 31, 2020, our total capital spending was $182 million, which included $141 million of expansion capital and $41 million of maintenance capital.  We spent an aggregate of $141 million for gathering and compression infrastructure.  The additional gathering and compression infrastructure included 34 miles of pipelines in the Appalachian Basin.  Additionally, we invested an aggregate of $41 million in water infrastructure to construct six miles of additional buried water pipelines and surface pipelines in the Appalachian Basin.  We also invested $25 million in our unconsolidated affiliates.

2021 Capital Budget

During 2021, we plan to expand our existing Appalachian Basin gathering, processing and water handling infrastructure to accommodate Antero Resources’ development plans. Antero Resources announced that it plans to operate three drilling rigs and complete between 65 and 70 horizontal wells, substantially all of which are expected to be located on acreage dedicated to us. Antero Resources’ announced 2021 drilling and completion capital budget is $590 million. Our 2021 capital budget is a range of $240 million to $260 million, which includes approximately $65 million of additional growth capital supporting the increased volumes expected from Antero Resources’ drilling partnership in addition to its previously disclosed maintenance capital program for 2021.

Our Assets

Our gathering and compression assets consist of high and low pressure gathering pipelines, compressor stations and processing and fractionation plants that collect and process natural gas and NGLs from Antero Resources’ wells in West Virginia and Ohio. Our water handling assets include two independent systems that deliver fresh water from sources, including the Ohio River, local reservoirs and several regional waterways, which portions of these systems are also utilized to transport flowback and produced water. The water handling systems consist of permanent buried pipelines, surface pipelines and fresh water storage facilities, as well as pumping stations and impoundments to transport fresh water throughout the systems used to deliver water to Antero Resources’ well completions. Our assets also include other flowback and produced water treatment facilities that we use to provide water treatment services to Antero Resources.

As of December 31, 2020, we had the ability to store 5.7 million barrels of fresh water in 37 impoundments. Additionally, we own water blending and storage assets to support other fluid handling services that we provide to Antero Resources for well completion and production activities. We also own water treatment assets, including the Antero Clearwater Facility, waste water pits and a related landfill used for the disposal of salt therefrom (collectively, the “Clearwater Facility”), which we idled in September 2019.

Idling of the Clearwater Facility

On September 18, 2019, we commenced a strategic evaluation of the Clearwater Facility. Based on the preliminary results of our evaluation and ongoing discussions with the Clearwater Facility’s contractor, the Clearwater Facility was idled. We expect the Clearwater Facility to continue to be idled for the foreseeable future. The decision to idle the Clearwater Facility was driven by its inability to operate at its intended specifications. Accordingly, we recorded impairment charges related to the Clearwater Facility of $409 million for property and equipment, $42 million of goodwill and $12 million in customer relationships during the year ended December 31, 2019. Additionally, during the year ended December 31, 2020, we determined that the carrying value of the landfill was no longer recoverable resulting in an impairment charge to property and equipment of $7 million. See Note 4—Clearwater Facility Idling to our consolidated financial statements. During the year ended December 31, 2019 and 2020, we incurred $11 million and $15 million, respectively, in facility idling costs for the care and maintenance of the Clearwater Facility. Since idling the Clearwater Facility, we have satisfied our obligation to handle Antero Resources’ flowback and produced water through our blending operations financial position and cash flows are dependentthird parties.

Our Relationship with Antero Resources

Antero Resources has a 29.2% ownership interest in us as of December 31, 2020. Antero Resources is our most significant customer and is one of the largest producers of natural gas and NGLs in the Appalachian Basin, where it produced, on average, 3.6 Bcfe/d net (33% liquids) during 2020, an increase of 11% as compared to 2019. As of December 31, 2020, Antero Resources’ estimated net proved reserves were 17.6 Tcfe, which were comprised of 57% natural gas, 42% NGLs and 1% oil. As of December 31, 2020, Antero Resources’ drilling inventory consisted of 2,133 identified potential horizontal well locations (approximately 1,531 of which were located on acreage dedicated to us) for gathering and compression and water handling services, which provides us with significant opportunities for growth as Antero Resources’ active drilling program continues and its production increases. Antero Resources announced its 2021 drilling and completion budget is $590 million, and includes plans to operate three drilling rigs, in the results of operations, financial positionAppalachian Basin. Antero Resources relies significantly on us to deliver the midstream infrastructure necessary to accommodate its production growth.

Initial Public Offering and Cash Distributions

On May 9, 2017, we completed our IPO of 37,250,000 common shares representing limited partnership interests at a price of $23.50 per common share. All of the common shares sold in the offering were offered by the selling shareholder. We did not receive any of the proceeds from the offering.

The board of directors of our general partner has declared cash distributions of $0.027, $0.059, and $0.075 per share for the second, third and fourth quarters of 2017, respectively.

Employees

We and our general partner have no employees. All of our officers and other personnel necessary for our business to function (to the extent not outsourced) are employedcompress natural gas produced by Antero Resources on any acreage it acquires in the future outside of West Virginia, Ohio and Pennsylvania on the same terms and conditions. Under the gathering and compression agreement, we receive a low pressure gathering fee per Mcf, a high-pressure gathering fee per Mcf and a compression fee per Mcf, in each case subject to CPI-based adjustments. If and to the extent Antero Resources requests that we construct new high pressure lines and compressor stations, the gathering and compression agreement contain options at our election for either (i) minimum volume commitments that require Antero Resources to utilize or pay for 75% and 70%, respectively, of the capacity of such new construction for 10 years or (ii) a service fee that allows us to earn a 13% rate of return on such new construction over seven years. Additional high pressure lines and compressor stations installed on our own initiative are not subject to these options. These minimum volume commitments and rate of return options on new infrastructure are intended to support the stability of our cash flows.

Antero Resources achieved all of its low pressure gathering growth incentive targets for 2020 and earned $48 million in fee reductions during the year. The following table summarizes the remaining low pressure gathering growth incentive targets for 2021 through 2023. If actual low pressure volumes are below the lowest tier for the respective calendar years, Antero Resources will not receive a reduction in low pressure gathering fees.

Water Handling Services

Pursuant to the water services agreement, we provide certain water handling services to Antero Resources within an area of dedication in defined service areas in Ohio and West Virginia. We also have certain rights of first offer with respect to water services for acreage located outside of the existing dedicated areas. Antero Resources agreed to pay us for all water handling services provided by us in accordance with the terms of the water services agreement, under which Antero Resources has no minimum volume commitments. Under the agreement, Antero Resources will pay a fixed fee per barrel in West Virginia and Ohio and all other locations for fresh water deliveries by pipeline directly to the well site. Antero Resources also agreed to pay us a fixed fee per barrel for wastewater treatment at the Clearwater Facility, which was idled in the third quarter of 2019 and we pay expect will remain idled for the foreseeable future. Additionally, we provide or manage other fluid handling services for well completion and production operations in Antero Resources’ operating areas. The fees for such services are all subject to CPI adjustments. In addition, we also provide fluid handling services for flowback and produced water, including blending, storage and transportation operations. These operations, along with our fresh water delivery systems, support well completion and production operations for Antero Resources. These services are provided by us directly or through third-parties with which we contract. For flowback and produced water services provided by third-parties, Antero Resources an annual fee for corporate, generalreimburses our third-party out-of-pocket costs plus 3%. For flowback and administrative services. This fee is initially $0.5 million per year and is subject to adjustment on an annual basis, beginning on January 1, 2018, based on the CPI. The fee is also subject to adjustment to reflect any increase in theproduced water services provided by us, we charge Antero Resources a cost of providing services due to changes in applicable law, rules or regulations and any increase in the scope and extentservice fee. The initial term of the water services provided. agreement runs to 2035.

Item 1A. Risk Factors

Limited partner interests are inherently different from the capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in a similar business. Because of our relationship with Antero Midstream and its relationship with Antero Resources, adverse developments or announcements concerning Antero Midstream or Antero Resources could materially adversely affect our business. You should carefully consider the following risk factors together with all of the other information included in this Annual Report on Form 10‑K, including the matters addressed under “Cautionary Statement Regarding Forward-Looking Statements,” in evaluating an investment in our common shares.

If any of the following risks were to occur, our business, financial condition, results of operations and cash available for distribution could be materially adversely affected.

For a discussion of Antero Midstream’s risk factors, please read Item 1A. “Risk Factors” of Antero Midstream’s Annual Report on Form 10‑K for the year ended December 31, 2017, which has been included in this filing as Exhibit 99.1 and incorporated herein by reference, as the activitiesprovision of Antero Midstream have a significant impact on our results of operations and financial position.

Risks Inherent in an Investment in Us

Our cash flows are entirely dependent upon the ability of Antero Midstream to make cash distributions on the IDRs.

We own all of the capital interests in IDR LLC, which owns all of the IDRs in Antero Midstream. Accordingly, the source of our earnings and cash flows currently consist exclusively of cash distributions from IDR LLC, which consist exclusively of cash distributions from Antero Midstream on the IDRs. We receive at least 94% of the cash distributions paid by Antero Midstream on the IDRs. The amount of cash that Antero Midstream is able to distribute to its partners, including IDR LLC, each quarter principally depends upon the amount of cash it generates from its business.

Antero Midstream may not have sufficient available cash each quarter to continue paying distributions at its current level or at all. If Antero Midstream reduces its per unit distribution, either because of reduced operating cash flow, higher expenses, increased capital requirements, increased common units outstanding (including common units issued in connection with Antero Midstream’s at‑the‑market equity offering program) or otherwise, we will have less cash available for distribution to you and would likely be required to reduce our per share distribution to you. You should also be aware that the amount of cash Antero Midstream has available for distribution depends primarily upon Antero Midstream’s cash flow, including borrowings, and is not solely a function of profitability, which is affected by non‑cash items. As a result, Antero Midstream may make cash distributions during periods when it records losses and may not make cash distributions during periods when it records profits.

Furthermore, our ability to distribute cash received in connection with distributions on the IDRs to our shareholders is limited by a number of factors, including:

·

the expenses we incur as a result of being a publicly traded company;

·

our payment of any income taxes;

·

interest expense and principal payments on any future indebtedness incurred by us;

·

distributions made by IDR LLC with respect to the Series B Units;

·

restrictions on distributions contained in Antero Midstream’s current revolving credit facility and any future debt agreements entered into by Antero Midstream or us; and

8


·

reserves, if any, our general partner establishes for the proper conduct of our business, to comply with applicable law or any agreement binding on us or our subsidiaries (exclusive of Antero Midstream and its subsidiaries), which reserves are not subject to a limit pursuant to our partnership agreement.

A material increase in amounts paid or reserved with respect to any of these factors could restrict our ability to pay quarterly distributions to our shareholders.

In the future, we may not have sufficient cash to pay our estimated initial quarterly distribution or to increase distributions.

Because our cash flows are entirely dependent on cash distributions from IDR LLC, which is dependent on cash distributions from Antero Midstream on the IDRs, the amount of distributions we are able to make to our shareholders may fluctuate based on the level of distributions Antero Midstream makes to its partners, including IDR LLC, and the level of distributions IDR LLC makes to its members, including us. We cannot assure you that Antero Midstream will continue to make quarterly distributions at its most recently declared level of $0.365 per unit, or any other level, or increase its quarterly distributions in the future. In addition, while we would expect to increase or decrease distributions to our shareholders if Antero Midstream were to increase or decrease distributions, the timing and amount of such changes in distributions, if any, would not necessarily be comparable to the timing and amount of any changes in distributions made by Antero Midstream. Various factors, such as reserves established by the board of directors of our general partner (including in anticipation of increasing distributions to our unitholders to account for make‑whole distributions paid by IDR LLC to the holders of newly‑vested Series B Units), may affect the distributions we make to our shareholders. The actual amount of cash that is available for distribution to our shareholders will depend on numerous factors, many of which are beyond our control or the control of our general partner.

Our right to receive distributions paid by Antero Midstream on the IDRs may be limited or modified by our general partner without the consent of our shareholders, which may reduce cash distributions to you.

We own all of the capital interests in IDR LLC, which owns all of the IDRs that entitle IDR LLC to receive increasing percentages (up to a maximum of 50%) of any cash distributed by Antero Midstream in excess of $0.1955 per Antero Midstream common unit in any quarter. We receive at least 94% of the cash distributions paid by Antero Midstream on the IDRs. All of the cash flows we receive from IDR LLC is derived from its ownership of these IDRs.

Antero Midstream, like other publicly traded partnerships, generally will undertake an acquisition or expansion capital project only if, after giving effect to related costs and expenses, the transaction would be expected to be accretive, meaning it would increase cash distributions per unit in future periods. Because IDR LLC currently participates in the IDRs at all levels, including the highest sharing level of 50%, an acquisition or capital project generally is less likely to be accretive to the unitholders of Antero Midstream than if the IDRs were entitled to a lower incremental cash flow. IDR LLC may receive a proposal to reduce the IDRs to facilitate a particular acquisition or expansion capital project. Any such reduction of IDRs will reduce the amount of cash that otherwise would have been distributed by IDR LLC to us, which will in turn reduce the cash distributions we otherwise would be able to pay to you. Our shareholders will not be able to vote on, or otherwise prohibit our general partner from taking, similar actions in the future and our general partner may elect to modify the incentive distributions. In addition, there can be no guarantee that the expected benefits of any IDR modification will be realized.

Additionally, IDR LLC has the right under Antero Midstream’s partnership agreement, subject to certain conditions, to elect to relinquish the right to receive incentive distribution payments based on the initial target distribution levels and to reset, at higher levels, the minimum quarterly distribution amount and target distribution levels upon which the incentive distribution payments to IDR LLC would be set. In connection with the resetting of the target distribution levels and the corresponding relinquishment by IDR LLC of incentive distribution payments based on the target cash distributions prior to the reset, IDR LLC will be entitled to receive a number of newly‑issued common units in Antero Midstream equal to the result of dividing (i) the aggregate amount of cash distributions made by Antero Midstream for the quarter immediately preceding the reset event by (ii) the cash distribution made by Antero Midstream in respect of each common unit for such quarter. IDR LLC’s right to reset the minimum quarterly distribution amount and target distribution levels upon which the incentive distributions payable to IDR LLC are based may be exercised, subject to certain

9


restrictions, without approval of Antero Midstream’s unitholders, our shareholders or Antero Midstream’s conflicts committee. The reset minimum quarterly distribution amount and target distribution levels will be higher than the minimum quarterly distribution amount and the target distribution levels prior to the reset such that IDR LLC will not receive any incentive distributions under the reset target distribution levels until cash distributions per unit following this event increase.

IDR LLC may exercise this reset right in order to facilitate acquisitions or internal growth projects that would otherwise not be sufficiently accretive to cash distributions per common unit, taking into account the existing levels of incentive distribution payments being made to the general partner.

A reduction in Antero Midstream’s distributions will disproportionately affect the amount of cash distributions on the IDRs.

IDR LLC’s ownership of Antero Midstream’s IDRs currently entitle it to receive increasing percentages, ranging from 15% up to 50%, of all cash distributed by Antero Midstream in excess of $0.1955 per common unit per quarter. Based on Antero Midstream’s distribution history, IDR LLC initially will be entitled to receive 50% of all cash distributed by Antero Midstream in excess of $0.2550 per common unit per quarter. A decrease in the amount of quarterly distributions paid by Antero Midstream to $0.2550 or less per common unit would reduce IDR LLC’s percentage of incremental quarterly cash distributions in excess of $0.1955 per common unit from 50% to 15%. As a result, any such reduction in quarterly cash distributions from Antero Midstream would have the effect of disproportionately reducing the amount of distributions that IDR LLC receives from Antero Midstream on the IDRs as compared to cash distributions Antero Midstream makes with respect to its common units.

If distributions on our common shares are not paid with respect to any fiscal quarter, our shareholders will not be entitled to receive any payments in respect of such quarter.

Our distributions to our shareholders are not cumulative. Consequently, if distributions on our common shares are not paid with respect to any fiscal quarter, our shareholders will not be entitled to receive any payments in respect of such quarter in the future.

The amount of cash that we and Antero Midstream distribute each quarter may limit our ability to grow.

Because we and Antero Midstream each distribute all of our respective cash from operations on a quarterly basis, our growth and Antero Midstream’s growth may not be as fast as the growth of businesses that continually reinvest their cash to expand ongoing operations. In fact, because our cash flows currently are generated solely from distributions we receive from IDR LLC, which are derived exclusively from the IDRs, our growth will be completely dependent upon Antero Midstream. The amount of distributions paid on the IDRs is based on the per unit distribution paid by Antero Midstream on each of its common units and the number of Antero Midstream common units outstanding. If we issue additional common shares or incur debt, the payment of distributions on those additional common shares or interest on that debt could increase the risk that we will be unable to maintain or increase our cash distribution levels.

Our rate of distribution growth may be reduced to the extent we purchase equity interests from Antero Midstream, which will reduce the relative percentage of the cash we receive from the IDRs.

Our business strategy includes, where appropriate, supporting the growth of Antero Midstream by making loans, purchasing equity interests or providing other forms of financial support to Antero Midstream to fund an acquisition of a business or asset or another growth project. To the extent we purchase equity interests from Antero Midstream that are not entitled to distributions or do not receive distributions at the same rates as the IDRs, the rate of our distribution growth may be reduced, at least in the short term, as less of our cash distributions will come from our ownership of IDRs, whose distributions increase at a faster rate than Antero Midstream’s common units and any similar equity interests Antero Midstream may issue in the future.

10


Restrictions in Antero Midstream’s existing and future debt agreements could limit Antero Midstream’s ability to make distributions to IDR LLC, and therefore IDR LLC’s ability to make distributions to us, which in turn would limit our ability to make distributions on our common shares.

Antero Midstream’s revolving credit facility and the indenture governing Antero Midstream’s outstanding senior notes contain various operating and financial restrictions and covenants. Antero Midstream’s ability to comply with these restrictions and covenants may be affected by events beyond its control, including prevailing economic, financial and industry conditions. If Antero Midstream is unable to comply with these restrictions and covenants, any indebtedness under this credit facility may become immediately due and payable and Antero Midstream’s lenders’ commitment to make further loans under this credit facility may terminate. Antero Midstream might not have, and might be unable to obtain, sufficient funds to satisfy these accelerated payment obligations.

Antero Midstream’s payment of principal and interest on any indebtedness will reduce its cash distributions on the IDRs, thereby reducing our cash available for distribution on our common shares. Antero Midstream’s revolving credit facility and the indenture governing Antero Midstream’s outstanding senior notes will limit our ability to pay distributions to our shareholders during an event of default or if an event of default would result from the distribution.

For more information regarding risks related to Antero Midstream’s debt agreements, please see “—Risks Related to Antero Midstream’s Business—“Restrictions in Antero Midstream’s revolving credit facility and future debt agreements could adversely affect its business, financial condition, results of operations and ability to make quarterly cash distributions to its unitholders.”

Our partnership agreement restricts the rights of shareholders owning 20% or more of our shares.

Our shareholders’ voting rights are restricted by the provision in our partnership agreement generally providing that any shares held by a person or group that owns 20% or more of any class of shares then outstanding, other than our general partner, the Sponsors (or certain transferees in private, non‑exchange transactions), their respective affiliates and persons who acquired such shares with the prior approval of our general partner’s board of directors, cannot be voted on any matter. In addition, our partnership agreement contains provisions limiting the ability of our shareholders to call meetings or to acquire information about our operations, as well as other provisions limiting our shareholders’ ability to influence the manner or direction of our management. As a result, the price at which our common shares will trade may be lower because of the absence or reduction of a takeover premium in the trading price.

Our shareholders will not elect or have the power to remove our general partner. The Sponsors will own a sufficient number of common shares to allow them to prevent the removal of our general partner.

Our shareholders only have limited voting rights on matters affecting our business and, therefore, limited ability to influence management’s decisions regarding our business. The board of directors of our general partner, including our independent directors, were initially designated and elected by the Sponsors or their designees following our IPO. Our remaining shareholders do not have the ability to elect our general partner or the members of the board of directors of our general partner unless the Sponsors no longer own specified amounts of our common shares. Additionally, as a result of our resulting governance arrangements and the 20% voting limitation in our partnership agreement, it will be difficult for one or more of our shareholders to gain control of our general partner’s board of directors.

In addition, if our shareholders are dissatisfied with the performance of our general partner, they have little ability to remove our general partner. Our general partner may not be removed unless that removal is for cause and is approved by the holders of at least 80% of our outstanding shares. The ownership level of the Sponsors enables the Sponsors to prevent our general partner’s removal.

As a result of these provisions, the price at which our common shares will trade may be lower because of the absence or reduction of a takeover premium in the trading price.

11


Our general partner may cause us to issue additional common shares, including in connection with the redemption of Series B Units, or other equity securities, as well as issue equity securities that are senior to our common shares, without your approval, which may adversely affect you.

Our general partner may cause us to issue an unlimited number of additional common shares, including in connection with the redemption of Series B Units, or other equity securities of equal rank with the common shares, without shareholder approval. In addition, we may issue an unlimited number of shares that are senior to our common shares in right of distribution, liquidation and voting. The issuance of additional common units or our other equity securities of equal or senior rank will have the following effects:

·

each shareholder’s proportionate ownership interest in us may decrease;

·

the amount of cash available for distribution on each common share may decrease;

·

the relative voting strength of each previously outstanding common share may be diminished; and

·

the market price of the common shares may decline.

If Antero Midstream’s unitholders remove AMP GP as the general partner of Antero Midstream, AMP GP would be required to sell or exchange its general partner interest, and we would lose the ability to manage and control Antero Midstream.

We own, and appoint all of the members of the board of directors of, AMP GP, which owns the non‑economic general partner interest in Antero Midstream. AMP GP may not be removed as general partner of Antero Midstream unless that removal is for cause and is approved by the vote of the holders of not less than 662/3% of the outstanding units of Antero Midstream, voting together as a single class, including units held by AMP GP and its affiliates, and Antero Midstream receives an opinion of counsel regarding limited liability and tax matters. Any removal of AMP GP is also subject to the approval of a successor general partner by the vote of the holders of a majority of the outstanding Antero Midstream common units, voting as a class. The ownership of more than 331/3% of the outstanding units by AMP GP and its affiliates gives them the ability to prevent our general partner’s removal. In the event of the removal of AMP GP as general partner of Antero Midstream or its withdrawal as general partner in violation of Antero Midstream’s partnership agreement, a successor general partner will have the option to purchase AMP GP’s general partner interest for a cash payment equal to the fair market value of that interest. Under all other circumstances where AMP GP withdraws as general partner of Antero Midstream, AMP GP will have the option to require the successor general partner to purchase the general partner interest of Antero Midstream for fair market value. In each case, this fair market value will be determined by agreement between AMP GP and the successor general partner. If no agreement is reached, an independent investment banking firm or other independent expert selected by AMP GP and the successor general partner will determine the fair market value. If, however, AMP GP and the successor general partner cannot agree upon an expert, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value. In each case, AMP GP would also lose its ability to manage Antero Midstream.

In addition, if AMP GP is removed as general partner of Antero Midstream, we would face an increased risk of being deemed an investment company.

Our shareholders may not have limited liability if a court finds that shareholder action constitutes control of our business.

Under Delaware law, our shareholders could be held liable for our obligations to the same extent as a general partner if a court determined that the right or the exercise of the right by our shareholders as a group to remove or replace our general partner, to approve some amendments to the partnership agreement or to take other action under our partnership agreement constituted participation in the “control” of our business. Additionally, the limitations on the liability of holders of limited partner interests for the liabilities of a limited partnership have not been clearly established in many jurisdictions.

12


Furthermore, Section 17‑607 of the Delaware Revised Uniform Limited Partnership Act provides that, under some circumstances, a shareholder may be liable to us for the amount of a distribution for a period of three years from the date of the distribution.

If in the future we cease to manage and control Antero Midstream, we may be deemed to be an investment company under the Investment Company Act of 1940.

If we cease to manage and control Antero Midstream or IDR LLC and are deemed to be an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”), we would either have to register as an investment company under the Investment Company Act, obtain exemptive relief from the SEC or modify our organizational structure or our contractual rights or asset mix to fall outside the definition of an investment company. Registering as an investment company could, among other things, materially limit our ability to engage in transactions with affiliates, including the purchase and sale of certain securities or other property to or from our affiliates, restrict our ability to borrow funds or engage in other transactions involving leverage, require us to add additional directors who are independent of us and our affiliates, and adversely affect the price of our common shares.

The price of our common shares may be volatile, and a trading market that will provide you with adequate liquidity may not develop.

The market price of our common shares could be subject to significant fluctuations, and may decline below the current price. You may be unable to resell your common shares at or above the current price. The following factors, among others, could affect our common share price:

·

Antero Midstream’s operating and financial performance and prospects and the trading price of its common units;

·

the level of Antero Midstream’s quarterly distributions and our quarterly distributions;

·

quarterly variations in the rate of growth of our financial indicators, such as distributable cash flow per common share, net income and revenues;

·

changes in revenue or earnings estimates or publication of research reports by analysts;

·

speculation by the press or investment community;

·

sales of our common shares by our shareholders;

·

the exercise by the Series B Holders of their redemption rights with respect to any vested Series B Units;

·

announcements by Antero Midstream or its competitors of significant contracts, acquisitions, strategic partnerships, joint ventures, securities offerings or capital commitments;

·

general market conditions;

·

changes in accounting standards, policies, guidance, interpretations or principles;

·

adverse changes in tax laws or regulations;

·

domestic and international economic, legal and regulatory factors related to Antero Midstream’s performance; and

·

other factors described in these “Risk Factors.”

Our common shares and Antero Midstream’s common units may not trade in relation or proportion to one another.

Our common shares and Antero Midstream’s common units may not trade in simple relation or proportion to one another. Instead, while the trading prices of our common shares and Antero Midstream’s common units are likely to follow generally similar broad trends, the trading prices may diverge because, among other things:

·

with respect to the first $0.1955 of distributable cash flow per common unit, Antero Midstream’s cash distributions to its unitholders have a priority over distributions on its IDRs;

·

our cash flows are more volatile than the cash flows paid to Antero Midstream’s unitholders because we participate in tiered incentive distributions associated with the IDRs in Antero Midstream while Antero Midstream’s unitholders participate in all distributions made by Antero Midstream;

·

IDR LLC will distribute a portion of the cash it receives from Antero Midstream to the holders of outstanding Series B Units;

·

we expect to continue to pay federal and state income taxes in the future; and

·

we may enter into other businesses separate and apart from Antero Midstream or any of its affiliates.

An increase in interest rates may cause the market price of our common shares to decline.

Like all equity investments, an investment in our common shares is subject to certain risks. In exchange for accepting these risks, investors may expect to receive a higher rate of return than would otherwise be obtainable from lower‑risk investments. Accordingly, as interest rates rise, the ability of investors to obtain higher risk‑adjusted rates of return by purchasing government‑backed debt securities may cause a corresponding decline in demand for riskier investments generally, including yield‑based equity investments such as publicly traded limited partnership interests. Reduced demand for our common shares resulting from investors seeking other more favorable investment opportunities may cause the trading price of our common shares to decline.

Future sales of our common shares in the public market could reduce our common share price, and any additional capital raised by us through the sale of equity or convertible securities may dilute your ownership in us.

Subject to certain limitations and exceptions, each Series B Holder may require IDR LLC to redeem all or a part of such holder’s vested Series B Units for common shares in us at a ratio described in the IDR LLC Agreement, subject to customary conversion rate adjustments for equity splits, equity dividends and reclassification and other similar transactions, and then sell those common shares. We may also issue additional common shares or convertible securities in subsequent public or private offerings. We cannot predict the size of future issuances of our common shares or securities convertible into common shares or the effect, if any, that future issuances and sales of our common shares will have on the market price of our common shares. Sales of substantial amounts of our common shares (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of our common shares.

The Sponsors hold a majority of the voting power of our common shares.

The Sponsors are entitled to act separately in their own respective interests with respect to their partnership interests in us, and have the ability to elect all of the members of our board of directors. In addition, they will be able to determine the outcome of all matters requiring shareholder approval, including certain mergers and other material transactions, and will be able to cause or prevent a change in the composition of our board of directors or a change in control of our company that could deprive our shareholders of an opportunity to receive a premium for their common shares as part of a sale of our company. So long as the Sponsors continue to own a significant amount of our outstanding shares, even if such amount is less than 50%, they will continue to be able to strongly influence all matters requiring

14


shareholder approval, regardless of whether or not other shareholders believe that the transaction is in their own best interests.

For as long as we are an emerging growth company, we will not be required to comply with certain reporting requirements, including those relating to accounting standards and disclosure about our executive compensation, that apply to other public companies.

The JOBS Act contains provisions that, among other things, relax certain reporting requirements for “emerging growth companies,” including certain requirements relating to accounting standards and compensation disclosure. We are classified as an emerging growth company. For as long as we are an emerging growth company, which may be up to five full fiscal years, unlike other public companies, we will not be required to, among other things, (1) provide an auditor’s attestation report on management’s assessment of the effectiveness of our system of internal control over financial reporting pursuant to Section 404(b) of the Sarbanes Oxley Act of 2002, (2) comply with any new requirements adopted by the PCAOB requiring mandatory audit firm rotation or a supplement to the auditor’s report in which the auditor would be required to provide additional information about the audit and the financial statements of the issuer, (3) comply with any new audit rules adopted by the PCAOB after April 5, 2012 unless the SEC determines otherwise, (4) provide certain disclosure regarding executive compensation required of larger public companies or (5) hold shareholder advisory votes on executive compensation.

If we or Antero Midstream fail to develop or maintain an effective system of internal controls, our ability to accurately report our financial results or prevent fraud could be adversely affected. As a result, our shareholders could lose confidence in our financial reporting, which would harm our business and the trading price of our common shares.

Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and operate successfully as a publicly traded company. We are required to comply with the SEC’s rules implementing Sections 302 and 404 of the Sarbanes‑Oxley Act of 2002, which require our management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our internal control over financial reporting. Though we are required to disclose material changes made to our internal controls and procedures on a quarterly basis, we will not be required to make our first annual assessment of our internal control over financial reporting pursuant to Section 404 until our annual report on Form 10-K for the year ended December 31, 2018. If we or Antero Midstream cannot provide reliable financial reports or prevent fraud, our and Antero Midstream’s reputation and operating results will be harmed. We cannot be certain that our efforts to develop and maintain our internal controls will be successful. Any failure to develop or maintain effective internal controls, or difficulties encountered in implementing or improving our internal controls, could harm our and Antero Midstream’s operating results or cause us or Antero Midstream to fail to meet our reporting obligations. Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which would likely have a negative effect on the trading price of our common shares and Antero Midstream’s common units.

The NYSE does not require a limited partnership like us to comply with certain of its corporate governance requirements.

Because we are a limited partnership, the NYSE does not require our general partner to have a majority of independent directors on its board of directors or to establish a compensation committee or a nominating and corporate governance committee. Accordingly, our shareholders will not have the same protections afforded to certain corporations that are subject to all of the NYSE corporate governance requirements. In addition, as a limited partnership we are not required to seek shareholder approval for issuances of common shares, including issuances in excess of 20% of our outstanding equity securities, or for issuances of equity to certain affiliates.

We may incur liability as a result of our ownership of Antero Midstream’s general partner.

Under Delaware law, a general partner of a limited partnership is generally liable for the debts and liabilities of the partnership for which it serves as general partner, subject to the terms of any indemnification agreements contained in the partnership agreement and except to the extent the partnership’s contracts are non‑recourse to the general partner. As

15


a result of our structure, we own all of the interests in and appoint all of the members of the board of directors of the general partner of Antero Midstream. To the extent the indemnification provisions in the applicable partnership agreement or non‑recourse provisions in our contracts are not sufficient to protect us from such liability, we may in the future incur liabilities as a result of our ownership of AMP GP.

Our general partner interest or the control of our general partner may be transferred to a third party without shareholder consent.

Our general partner may transfer its general partner interest to a third party, including in a merger or in a sale of all or substantially all of its assets, without the consent of our shareholders. Furthermore, the Sponsors may transfer all or a portion of their ownership interests in our general partner to a third party, also without shareholder consent. The new owners of our general partner would then be in a position to replace the board of directors and officers of our general partner with its own designees and thereby exert significant control over the decisions made by the board of directors and officers.

The future debt that we incur may limit the distributions that we can pay to our shareholders.

Our payment of principal and interest on any future indebtedness will reduce our cash available for distribution to our shareholders. We anticipate that any credit facility we enter into in the future would limit our ability to pay distributions to our shareholders during an event of default or if an event of default would result from the distributions.

Moreover, any future indebtedness may adversely affect our ability to obtain additional financing for future operations or capital needs, limit our ability to pursue other business opportunities, or make our results of operations more susceptible to adverse economic or operating conditions.

The amount of cash distributions that we will be able to distribute to our shareholders will be reduced by the incremental costs associated with our being a publicly traded company, other general and administrative expenses and any reserves that our general partner believes it is prudent to maintain for the proper conduct of our business and for future distributions.

Before we can pay distributions to our shareholders, we will first pay our expenses, including the costs of being a publicly traded company, which we expect to be approximately $1.5 million per year, and taxes and other expenses, and may establish reserves for debt service requirements, if any, for future distributions during periods of limited cash flows or for other purposes.

Risks Related to Conflicts of Interest

Our existing organizational structure and the relationships among us, Antero Midstream, our respective general partners, Antero Resources, the Sponsors and affiliated entities present the potential for conflicts of interest. Moreover, additional conflicts of interest may arise in the future among us and the entities affiliated with any general partner or similar interests we acquire or among Antero Midstream and such entities.

Certain holders of our common shares have investments in our affiliates that may conflict with the interests of other holders of our common shares.

Certain funds affiliated with Warburg Pincus LLC (“Warburg”), certain funds affiliated with Yorktown Partners LLC (“Yorktown”), Paul M. Rady and Glen C. Warren, Jr. (collectively, the “Sponsors”) collectively own 100% of our general partner and a majority of our outstanding common shares. Messrs. Rady and Warren also own a portion of the Series B Units in IDR LLC. Affiliates of Warburg and Yorktown, Mr. Rady and Mr. Warren serve as members of the board of directors of our general partner, the board of directors of Antero Resources, and the board of directors of Antero Midstream’s general partner, and each of Warburg and Yorktown are controlled in part by individuals who serve as members of the board of directors of our general partner, the board of directors of Antero Resources, and the board of directors of Antero Midstream’s general partner. The Sponsors also own common units representing limited partner interests in Antero Midstream and shares of common stock in Antero Resources. Please see “Item 11. Executive

16


Compensation—Narrative Disclosure to Summary Compensation Table—Long-Term Equity-Based Incentive Awards—Series B Units in IDR LLC” for more information regarding the Series B Units in IDR LLC.As a result of their investments in Antero Midstream and Antero Resources, the Sponsors may have conflicts of interest with other holders of our common shares. These conflicts of interest could arise in the future between us, on the one hand, and the Sponsors, on the other hand, regarding, among other things, decisions to modify or limit the IDRs in the future, the terms of our agreements with Antero Midstream and Antero Resources and their respective subsidiaries and the pursuit of potentially competitive business activities or business opportunities.

Conflicts of interest may arise as a result of our organizational structure and the relationships among us, Antero Midstream, our respective general partners, Antero Resources and other affiliated entities.

Our partnership agreement defines the duties of our general partner (and, by extension, its officers and directors). Our general partner’s board of directors or its conflicts committee will have authority on our behalf to resolve any conflict involving us and they have broad latitude to consider the interests of all parties to the conflict.

Conflicts of interest may arise between us and our shareholders, on the one hand, and our general partner and affiliated entities, on the other hand, or between us and our shareholders, on the one hand, and Antero Midstream and its unitholders, on the other hand. The resolution of these conflicts may not always be in our best interest or that of our shareholders.

Our partnership agreement defines our general partner’s duties to us and contains provisions that reduce the remedies available to our shareholders for actions that might otherwise be challenged as breaches of fiduciary or other duties under state law.

Our partnership agreement contains provisions that substantially reduce the standards to which our general partner would otherwise be held by state fiduciary duty law. 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. This entitles our general partner to consider only the interests and factors that it desires, and it has no duty or obligation to give any consideration to any interest of, or factors affecting, us, the Sponsors, our affiliates or any limited partner. Examples include the exercise of its limited call right, its rights to transfer or vote any shares it may own, and its determination whether or not to consent to any merger or consolidation of our partnership or amendment to our partnership agreement;

·

generally provides that our general partner will not have any liability to us or our shareholders for decisions made in its capacity as a general partner so long as it acted in good faith which, pursuant to our partnership agreement, requires a subjective belief that the determination, or other action or anticipated result thereof is in, or not opposed to, our best interests;

·

generally provides that any resolution or course of action adopted by our general partner and its affiliates in respect of a conflict of interest will be permitted and deemed approved by all of our shareholders, and will not constitute a breach of our partnership agreement or any duty stated or implied by law or equity if the resolution or course of action in respect of such conflict of interest is:

·

approved by a majority of the members of our general partner’s conflicts committee after due inquiry, based on a belief that the course of action or determination that is the subject of such approval is not adverse to us;

·

approved by majority vote of our common shares (excluding shares owned by our general partner and its affiliates, but including shares owned by the Sponsors) voting together as a single class;

·

provides that, to the fullest extent permitted by law, in connection with any action or inaction of, or determination made by, our general partner or the conflicts committee of our general partner’s board of

17


directors with respect to any matter relating to us, it shall be presumed that our general partner or the conflicts committee of our general partner’s board of directors acted in a manner that satisfied the contractual standards set forth in our partnership agreement, and in any proceeding brought by any limited partner or by or on behalf of such limited partner or any other limited partner or our partnership challenging any such action or inaction of, or determination made by, our general partner, the person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption; and

·

provides that our general partner and its officers and directors will not be liable for monetary damages to us, our limited partners or assignees for any acts or omissions unless there has been a final and non‑appealable judgment entered by a court of competent jurisdiction determining that our general partner or those other persons acted in bad faith or, in the case of a criminal matter, acted with knowledge that such person’s conduct was criminal.

The Sponsors may have interests that conflict with holders of our common shares.

The Sponsors own a certain number of our outstanding shares and certain of the Sponsors own a portion of the Series B Units in IDR LLC. In addition, certain of the Sponsors own a portion of Antero Midstream’s common units and Antero Resources’ common stock. As a result, the Sponsors may have conflicting interests with holders of our common shares.

Furthermore, conflicts of interest could arise in the future between us, on the one hand, and the Sponsors, on the other hand, concerning among other things, a decision whether to modify or limit the IDRs in the future or potential competitive business activities or business opportunities. These conflicts of interest may not be resolved in our favor.

Antero Resources does not own our general partner and is under no obligation to adopt a business strategy that favors us.

The directors and officers of Antero Resources have a fiduciary duty to make decisions in the best interests of the owners of Antero Resources, which may be contrary to our interests. Antero Resources has dedicated acreage to, and entered into long‑term contracts for gathering and compression services on, Antero Midstream’s gathering and compression systems, as well as long‑term contracts for receiving water services. However, while Antero Midstream has a 20‑year right of first offer to provide processing and fractionation services pursuant to which Antero Resources, subject to certain exceptions, may not procure any gas processing or NGL fractionation services with respect to its production (other than production subject to a pre-existing dedication) without first offering us the right to provide such services. For additional information, please read “—Antero Resources’ Existing Third-Party Commitments.”

Secondment and Services Agreements

Pursuant to a secondment agreement and a services agreement, Antero Resources is under no obligationseconds employees to consider whetherus to provide operational services with respect to our assets and certain corporate, general and administrative services in exchange for

reimbursement of any futuredirect expenses and an allocation of any indirect expenses attributable to its provision of such services. These agreements extend through 2039.

Antero Resources’ Existing Third-Party Commitments

Excluded Acreage

Antero Resources previously dedicated a portion of its acreage in the Appalachian Basin to certain third parties’ gathering and compression services. We refer to this acreage dedication as the “excluded acreage.” As of December 31, 2020, the excluded acreage consisted of approximately 135,000 of Antero Resources’ existing gross leasehold acreage, which included approximately 602 of Antero Resources’ 2,133 potential horizontal well locations. As part of its five year drilling plans would create beneficial opportunitiesplan, Antero Resources expects to drill most of its wells on acreage dedicated to us.

Other Commitments

In addition to the excluded acreage, Antero Resources has entered into contracts with certain third-parties that include minimum volume commitments for high pressure gathering and/or compression services. Specifically, those volume commitments consist of up to an aggregate of 450 MMcf/d on high pressure gathering pipelines and approximately 560 MMcf/d for compression services.

Acreage Dispositions

In addition to the excluded acreage and Antero Midstream. Additionally, although Antero Midstream’sResources’ other commitments with third parties, each of the gathering and compression agreement, water services agreement and right of first offer agreement between Antero Resources and us permit Antero Resources to sell, transfer, convey, assign, grant or otherwise dispose of dedicated properties free of the dedication under such agreements, provided that the number of net acres of dedicated properties so disposed of, when added to the number of net acres of dedicated properties previously disposed of free of the dedication since the respective effective dates of the agreements, does not exceed the aggregate number of net acres of dedicated properties acquired by Antero Resources since such effective dates. Accordingly, under certain circumstances, Antero Resources may dispose of a significant number of net acres of dedicated properties free from dedication without our consent, and we have no control over the timing or extent of such dispositions.

Title to Properties

Our real property is classified into two categories: (1) parcels that we own in fee and (2) parcels in which our interest derives from leases, easements, rights-of-way, permits or licenses from landowners or governmental authorities, permitting the use of such land for our operations. Portions of the land on which our pipelines and major facilities are located are owned by us in fee title, and we believe that we have satisfactory title to these lands. The remainder of the land on which our pipelines and major facilities are located are held by us pursuant to surface leases between us, as lessee, and the fee owner of the lands, as lessors. We have leased or owned these lands without any material challenge known to us relating to the title to the land upon which the assets are located, and we believe that we have satisfactory leasehold estates or fee ownership of such lands. We have no knowledge of any challenge to the underlying fee title of any material lease, easement, right-of-way, permit or license held by us or to our title to any material lease, easement, right-of-way, permit or lease, and we believe that we have satisfactory title to all of its material leases, easements, rights-of-way, permits and licenses.

Seasonality

Demand for natural gas generally decreases during the spring and fall months and increases during the summer and winter months. However, seasonal anomalies such as mild winters or mild summers sometimes lessen this fluctuation. In addition, certain natural gas end users, utilities and marketers utilize natural gas storage facilities and purchase some of their anticipated winter requirements during the spring, summer and fall, thereby smoothing demand for natural gas. This can also lessen seasonal demand fluctuations. These seasonal anomalies can increase demand for our services during the summer and winter months and decrease demand for our services during the spring and fall months.

Competition

As a result of our relationship with Antero Resources, we do not compete for the portion of Antero Resources’ existing operations for which we currently provide midstream services and will not compete for future portions of Antero Resources’ operations that are dedicated to us pursuant to: (i) our gathering and compression agreement; (ii) our water handling services agreement; and (iii) our right-of-first-offer agreement with Antero Resources for the provision of processing and fractionation

services. For a description of this contract, please read “—Our Relationship with Antero Resources—Contractual Arrangements with Antero Resources.” However, we face competition in attracting third-party volumes to our gathering and compression and water handling systems. In addition, these third parties may develop their own gathering and compression and water handling systems in lieu of employing our assets.

Regulation of Operations

Regulation of pipeline gathering services may affect certain aspects of our business and the market for our services.

Gathering Pipeline Regulation

Section 1(b) of the Natural Gas Act of 1938 (“NGA”), exempts natural gas gathering facilities from regulation by the FERC, under the NGA. Although the FERC has not made any formal determinations with respect to any of our facilities, we believe that the natural gas pipelines in our gathering systems meet the traditional tests the FERC has used to establish whether a pipeline is a gathering pipeline not subject to FERC jurisdiction. The distinction between FERC-regulated transmission services and federally unregulated gathering services, however, has been the subject of substantial litigation, and the FERC determines whether facilities are gathering facilities on a case-by-case basis, so the classification and regulation of some our gathering facilities and intrastate transportation pipelines may be subject to change based on future determinations by the FERC, the courts or Congress. If the FERC were to consider the status of an individual facility and determine that the facility is not a gathering pipeline and the pipeline provides interstate transmission service, the rates for, and terms and conditions of, services provided by such facility would be subject to regulation by the Joint Venture are supportedFERC under the NGA or the Natural Gas Policy Act of 1978 (“NGPA”). Such FERC-regulation could decrease revenue, increase operating costs, and, depending upon the facility in question, could adversely affect our results of operations and cash flows. In addition, if any of our facilities were found to have provided services or otherwise operated in violation of the NGA or NGPA, this could result in the imposition of civil penalties as well as a requirement to disgorge charges collected for such service in excess of the rate established by minimum volume commitments,the FERC.

Unlike natural gas gathering under the NGA, there is no exemption for the gathering of crude oil or NGLs under the Interstate Commerce Act (“ICA”). Whether a crude oil or NGL shipment is in interstate commerce under the ICA depends on the fixed and persistent intent of the shipper as to the crude oil’s or NGL’s final destination, absent a break in the interstate movement. Antero Midstream believes that the crude oil and NGL pipelines in its gathering system meet the traditional tests the FERC has used to determine that a pipeline is not providing transportation service in interstate commerce subject to FERC ICA jurisdiction. However, the determination of the interstate or intrastate character of shipments on Antero Midstream’s crude oil and NGL pipelines depends on the shipper’s intentions and the transportation of the crude oil or NGLs outside of Antero Midstream’s system, and may change over time. If the FERC were to consider the status of an individual facility and the character of a crude oil or NGL shipment, and determine that the shipment is in interstate commerce, the rates for, and terms and conditions of, transportation services provided by such facility would be subject to regulation by the FERC under the ICA. Such FERC regulation could decrease revenue, increase operating costs and, depending on the facility in question, could adversely affect Antero Midstream’s results of operations and cash flows. In addition, if any of Antero Midstream’s facilities were found to have provided services or otherwise operated in violation of the ICA, this could result in the imposition of administrative and civil remedies and criminal penalties, as well as a requirement to disgorge charges collected for such services in excess of the rate established by the FERC.

State regulation of gathering facilities generally includes various safety, environmental and, in some circumstances, nondiscriminatory take requirements and complaint-based rate regulation. States in which we operate may adopt ratable take and common purchaser statutes, which would require our gathering pipelines to take natural gas without undue discrimination in favor of one producer over another producer or one source of supply over another similarly situated source of supply. The regulations under these statutes may have the effect of imposing some restrictions on our ability as an owner of gathering facilities to decide with whom we contract to gather natural gas. States in which we operate may also adopt a complaint-based regulation of natural gas gathering activities, which allows natural gas producers and shippers to file complaints with state regulators in an effort to resolve grievances relating to gathering access and rate discrimination. We cannot predict whether such regulation will be adopted and whether such a complaint will be filed against us in the future. Failure to comply with state regulations can result in the imposition of administrative, civil and criminal remedies. To date, there has been no adverse effect to our system due to state regulations.

Our gathering operations could be adversely affected should they be subject in the future to more stringent application of state regulation of rates and services. Our gathering operations also may be, or become, subject to additional safety and operational regulations relating to the design, installation, testing, construction, operation, replacement and management of gathering facilities. Additional rules and legislation pertaining to these matters are considered or adopted from time to time. We cannot predict what effect, if any, such changes might have on our operations, but the industry could be required to incur additional capital expenditures and increased costs depending on future legislative and regulatory changes.

Table of Contents

The Energy Policy Act of 2005 (“EPAct 2005”), amended the NGA and NGPA to prohibit fraud and manipulation in natural gas markets. The FERC subsequently issued a final rule making it unlawful for any entity, in connection with the purchase or sale of natural gas or transportation service subject to FERC’s jurisdiction, to defraud, make an untrue statement or omit a material fact or engage in any practice, act or course of business that operates or would operate as a fraud. The FERC’s anti-manipulation rules apply to intrastate sales and gathering activities only to the extent that there is a “nexus” to FERC-jurisdictional transactions. EPAct 2005 also provided the FERC with the authority to impose civil penalties of up to approximately $1 million (adjusted annually for inflation) per day per violation. In January 2021, FERC issued an order (Order No. 865) increasing the maximum civil penalty amounts under the NGA and NGPA to adjust for inflation. FERC may now assess civil penalties under the NGA and NGPA of up to $1,307,164 per violation per day.

Pipeline Safety Regulation

Some of our gas pipelines are subject to regulation by the Pipeline and Hazardous Materials Safety Administration (“PHMSA”), pursuant to the Natural Gas Pipeline Safety Act of 1968 (“NGPSA”), with respect to natural gas, and the Hazardous Liquids Pipeline Safety Act of 1979 (“HLPSA”), with respect to crude oil and NGLs. Both the NGPSA and the HLPSA were amended by the Pipeline Safety Act of 1992, the Accountable Pipeline Safety and Partnership Act of 1996, the Pipeline Safety Improvement Act of 2002 (“PSIA”), as reauthorized and amended by the Pipeline Inspection, Protection, Enforcement and Safety Act of 2006 (the “PIPES Act”), and the Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011 (“2011 Pipeline Safety Act”). The NGPSA and HLPSA regulate safety requirements in the design, construction, operation and maintenance of natural gas, crude oil and NGL pipeline facilities, while the PSIA establishes mandatory inspections for all U.S. crude oil, NGL and natural gas transmission pipelines in high-consequence areas or high consequence areas (“HCAs”).

The PHMSA has developed regulations that require pipeline operators to implement integrity management programs, including more frequent inspections and other measures to ensure pipeline safety in HCAs. The regulations require operators, including us, to:

perform ongoing assessments of pipeline integrity;

identify and characterize applicable threats to pipeline segments that could impact an HCA;

improve data collection, integration and analysis;

repair and remediate pipelines as necessary; and

implement preventive and mitigating actions.

The 2011 Pipeline Safety Act, among other things, increased the maximum civil penalty for pipeline safety violations and directed the Secretary of Transportation to promulgate rules or standards relating to expanded integrity management requirements, automatic or remote-controlled valve use, excess flow valve use, leak detection system installation and testing to confirm the material strength of pipe operating above 30% of specified minimum yield strength in HCAs. Consistent with the act, PHMSA finalized rules that increased the maximum administrative civil penalties for violation of the pipeline safety laws and regulations to $200,000 per violation per day, with a maximum of $2,000,000 for a series of violations. Those maximum civil penalties have increased to $218,647 per violation per day, with a maximum of $2,186,465 for a series of violations, to account for inflation. The PHMSA has also issued a final rule applying safety regulations to certain rural low-stress hazardous liquid pipelines that were not covered previously by some of its safety regulations.

Following legislation enacted by Congress, PHMSA has issued or proposed regulations that either seek to impose new obligations on pipeline operations or expand existing pipeline safety requirements to previously unregulated pipelines. For example, in October 2019, PHMSA published three final rules on pipeline safety. The Enhanced Emergency Order Procedures rule (effective December 2, 2019) implements an existing statutory authorization for PHMSA to issue emergency orders related to pipeline safety if unsafe conditions or practices, or a combination thereof, constitutes or causes an imminent hazard. The Safety of Hazardous Liquid Pipelines rule (effective July 1, 2020) expands PHMSA’s regulation of the safety of hazardous liquid pipelines by extending reporting requirements to certain hazardous liquid gravity flow and rural gathering pipelines, establishing new requirements for integrity management programs for hazardous liquid pipelines in HCAs and certain other hazardous liquid pipelines and expanding various inspection and leak detection requirements. The Safety of Gas Transmission Pipelines rule (effective July 1, 2020) requires operators of certain gas transmission pipelines to reconfirm the Maximum Allowable Operating Pressure (MAOP) of their lines and establishes a new “Moderate Consequence Area” for determining regulatory requirements for gas transmission pipeline segments outside of HCAs. The rule also establishes new requirements for conducting baseline assessments and incorporates industry standards and

guidelines as well as new requirements for integrity management programs. We are in the process of assessing the impact of these rules on our future costs of operations and revenue from operations, but we do not expect our operations to be affected by these new rules any differently than other similarly situated midstream companies.

PHMSA has also been working on two additional rules related to gas pipeline safety, though we cannot predict when they will be finalized. The rule entitled “Pipeline Safety: Safety of Gas Transmission Pipelines, Repair Criteria, Integrity Management Improvements, Cathodic Protection, Management of Change and Other Related Amendments” is expected to adjust the repair criteria for pipelines in HCAs, create new criteria for pipelines in non-HCAs and strengthen integrity management assessment requirements. The rule entitled “Safety of Gas Gathering Pipelines” is expected to require all gas gathering pipeline operators to report incidents and annual pipeline data and to extend regulatory safety requirements to certain gas gathering pipelines in rural areas.

Separately, in the Fiscal Year 2021 Omnibus Appropriations Bill, Congress directed PHMSA to move forward with several regulatory actions, including the “Pipeline Safety: Class Location Change Requirements” and the “Pipeline Safety: Safety of Gas Transmission and Gathering Pipelines” proposed rulemakings. Congress has also instructed PHMSA to issue final regulations to require operators of non-rural gas gathering lines and new and existing transmission and distribution pipeline facilities to conduct certain leak detection and repair programs and to require facility inspection and maintenance plans to align with those regulations. While we cannot predict the full scope of these regulations at this time, more stringent requirements may require us to incur significant costs to maintain compliance, which may have a negative impact on our business performance and results of operations.

States are largely preempted by federal law from regulating pipeline safety for interstate lines but most are certified by the DOT to assume responsibility for enforcing federal intrastate pipeline regulations and inspection of intrastate pipelines. States may adopt stricter standards for intrastate pipelines than those imposed by the federal government for interstate lines; however, states vary considerably in their authority and capacity to address pipeline safety. State standards may include requirements for facility design and management in addition to requirements for pipelines. We do not anticipate any significant difficulty in complying with applicable state laws and regulations.

We regularly review all existing and proposed pipeline safety requirements and work to incorporate the new requirements into procedures and budgets. We expect to incur increasing regulatory compliance costs, based on the intensification of the regulatory environment and upcoming changes to regulations as outlined above, consistent with other similarly situated midstream companies. In addition to regulatory changes, costs may be incurred if there is an accidental release of a commodity transported by our system, or a regulatory inspection identifies a deficiency in our required programs and corrective action is required.

Regulation of Environmental and Occupational Safety and Health Matters

General

Our natural gas gathering and compression agreement includes minimum volumes commitments onlyand water handling activities are subject to stringent and complex federal, state and local laws and regulations relating to the protection of the environment, natural resources and worker safety. As an owner or operator of these facilities, we must comply with these laws and regulations at the federal, state and local levels. These laws and regulations can restrict or impact our business activities in many ways, such as:

requiring the installation of pollution-control equipment, imposing emission or discharge limits or otherwise restricting the way we operate resulting in additional costs to our operations;

limiting or prohibiting construction activities in areas, such as air quality nonattainment areas, wetlands, coastal regions or areas inhabited by endangered or threatened species;

delaying system modification or upgrades during review of permit applications and revisions;

requiring investigatory and remedial actions to mitigate discharges, releases or pollution conditions associated with our operations or attributable to former operations; and

enjoining the operations of facilities deemed to be in non-compliance with permits issued pursuant to or regulatory requirements imposed by such environmental laws and regulations.

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 and natural resource damages. Certain environmental statutes impose strict joint and several liability for costs required to clean up and restore sites where hazardous substances, hydrocarbons or solid wastes

have been disposed or otherwise released. Moreover, neighboring landowners and other third parties may file common law claims for personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or solid waste into the environment.

The trend in environmental regulation has been to place more restrictions and limitations on high‑pressure pipelinesactivities that may affect the environment and compressor stations constructed at Antero Resources’ request afterthus, there can be no assurance as to the Antero Midstream IPO. A reductionamount or timing of future expenditures for environmental compliance or remediation and actual future expenditures may be different from the amounts we currently anticipate. As with the midstream industry in thegeneral, complying with current levels of throughput volumes on Antero Midstream’s gathering and compression systems by Antero Resources couldanticipated environmental laws and regulations can increase our capital costs to construct, maintain and operate equipment and facilities. While these laws and regulations affect our maintenance capital expenditures and net income, we do not believe they will have a material adverse effect on Antero Midstream’sour business, financial condition,position, results of operations and ability to make quarterlyor cash distributions to its unitholders, including us.

Our general partner’s affiliates andflows, nor do we believe that they will affect our competitive position since the Sponsors may compete with us.

Our partnership agreement providesoperations of our competitors are generally similarly affected. In addition, we believe that our general partner will be restricted from engagingthe various activities in any business activities other than acting as our general partner and those activities incidental to its ownership of interests in us. The restrictions contained in our general partner’s limited liability company agreementwhich we are presently engaged that are subject to environmental laws and regulations are not expected to materially interrupt or diminish our operational ability to gather natural gas and provide water handling services. We cannot assure you, however, that future events, such as changes in existing laws or enforcement policies, the promulgation of new laws or regulations or the development or discovery of new facts or conditions will not cause us to incur significant costs. Below is a numberdiscussion of exceptions. Affiliatesthe material environmental laws and regulations that relate to our business.

Hydraulic Fracturing Activities

Hydraulic fracturing is an important and common practice that is used to stimulate production of natural gas and/or oil from dense subsurface rock formations. The hydraulic fracturing process involves the injection of water, sand and chemicals under pressure through a cased and cemented wellbore into targeted subsurface formations to fracture the surrounding rock and stimulate production. Our primary customer, Antero Resources, uses the water we deliver to it for hydraulic fracturing as part of its completion operations as does most of the U.S. onshore oil and natural gas industry. Hydraulic fracturing is typically regulated by state oil and gas commissions and similar agencies; however, in recent years the EPA, has asserted limited authority over hydraulic fracturing and has issued or sought to propose rules related to the control of air emissions, disclosure of chemicals used in the process and the disposal of flowback and produced water resulting from the process. Some 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. For example, in July 2015, the Ohio Department of Natural Resources issued final rules for horizontal drilling well-pad construction. The Ohio legislature has also adopted laws requiring oil and natural gas operators to disclose chemical ingredients used to hydraulically fracture wells and to conduct pre-drilling baseline water quality sampling of certain water wells near a proposed horizontal well. Local governments also may seek to adopt ordinances within their jurisdictions regulating the time, place and manner of drilling activities in general or hydraulic fracturing activities in particular. Some states and municipalities have sought to ban hydraulic fracturing altogether. We cannot predict whether any such federal, state or local legal restrictions relating to the hydraulic fracturing process will ever be enacted in areas where our customers operate and if so, what the effects of such restrictions would be. If additional levels of regulation and permits were required through the adoption of new laws and regulations at the federal state or local level, that could lead to delays, increased operating costs and process prohibitions that could reduce the volumes of water and natural gas that move through our systems, which in turn could materially adversely affect our revenues and results of operations.

Hazardous Waste

Antero Midstream and Antero Resources’ operations generate solid wastes, including small quantities of hazardous wastes, that are subject to the federal Resource Conservation and Recovery Act (“RCRA”), and comparable state laws, which impose requirements for the handling, storage, treatment and disposal of hazardous waste. RCRA currently exempts many oil and natural gas gathering and field processing wastes from classification as hazardous waste. Specifically, RCRA excludes from the definition of hazardous waste produced waters and other wastes intrinsically associated with the exploration, development or production of crude oil and natural gas, including residual constituents derived from those exempt wastes. However, these oil and gas exploration and production wastes may still be regulated under state solid waste laws and regulations and it is possible that certain oil and natural gas exploration and production wastes now classified as exploration and production-exempt non-hazardous waste could be classified as hazardous waste in the future. Stricter regulation of wastes generated during our or our customer’s operations could result in increased costs for our operations or the operations of our general partnercustomers, which could in turn reduce demand for our services, increase our waste disposal costs and adversely affect our business.

Site Remediation

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as the Superfund law and comparable state laws impose liability without regard to fault or the legality of the original conduct, on certain classes of

9

Table of Contents

persons responsible for the release of hazardous substances into the environment. Such classes of persons include the current and past owners or operators of sites where a hazardous substance was released and companies that disposed or arranged for disposal of hazardous substances at offsite locations, such as landfills. Although petroleum as well as natural gas is excluded from CERCLA’s definition of “hazardous substance,” in the course of our ordinary operations, our operations generate wastes that may be designated as hazardous substances. CERCLA authorizes the EPA, states, and, in some cases, third parties to take actions in response to releases or threatened releases of hazardous substances into the environment and to seek to recover from the classes of responsible persons the costs they incur to address the release. Under CERCLA, we could be subject to strict joint and several liabilities for the costs of cleaning up and restoring sites where hazardous substances have been released into the environment and for damages to natural resources.

We currently own or lease, and may have in the past owned or leased, properties that have been used for the gathering and compression of natural gas and the Sponsors willgathering and transportation of oil. Although we typically used operating and disposal practices that were standard in the industry at the time, petroleum hydrocarbons or wastes may have been disposed of or released on or under the properties owned or leased by it or on or under other locations where such substances have been taken for disposal. Such petroleum hydrocarbons or wastes may have migrated to property adjacent to our owned and leased sites or the disposal sites. In addition, some of the properties may have been operated by third parties or by previous owners whose treatment and disposal or release of petroleum hydrocarbons or wastes was not under our control. These properties and the substances disposed or released on them may be subject to CERCLA, RCRA and analogous state laws. Under such laws, we could be required to remove previously disposed wastes, including waste disposed of by prior owners or operators; remediate contaminated property, including groundwater contamination, whether from prior owners or operators or other historic activities or spills; or perform remedial operations to prevent future contamination. We are not currently a potentially responsible party in any federal or state Superfund site remediation and there are no current, pending or anticipated Superfund response or remedial activities at or implicating our facilities or operations.

Air Emissions

The federal Clean Air Act, and comparable state laws, regulate emissions of air pollutants from various industrial sources, including natural gas processing plants and compressor stations, and also impose various emission limits, operational limits and monitoring, reporting and recordkeeping requirements on air emission sources. Failure to comply with these requirements could result in monetary penalties, injunctions, conditions or restrictions on operations and potentially criminal enforcement actions. These laws are frequently subject to change. For example, in October 2015, the EPA lowered the National Ambient Air Quality Standard (“NAAQS”), for ozone from 75 to 70 parts per billion, and completed attainment/non-attainment designations in July 2018. State implementation of the revised NAAQS could result in stricter permitting requirements, delay or prohibit our ability to obtain such permits, and result in increased expenditures for pollution control equipment, the costs of which could be significant. Applicable laws and regulations require pre-construction permits for the construction or modification of certain projects or facilities with the potential to emit air emissions above certain thresholds. These pre-construction permits generally require use of best available control technology (“BACT”), to limit air emissions. Several EPA new source performance standards (“NSPS”), and national emission standards for hazardous air pollutants (“NESHAP”), also apply to our facilities and operations. These NSPS and NESHAP standards impose emission limits and operational limits as well as detailed testing, recordkeeping and reporting requirements on the “affected facilities” covered by these regulations. Several of our facilities are “major” facilities requiring Title V operating permits which impose semi-annual reporting requirements.

Water Discharges

The Federal Water Pollution Control Act (the “Clean Water Act”), and comparable state laws impose restrictions and strict controls regarding the discharge of pollutants, including produced waters and other oil and natural gas wastes, into federal and state waters. The discharge of pollutants into regulated waters is prohibited, from engagingexcept in accordance with the terms of a permit issued by the EPA or the state. The discharge of dredge and fill material in regulated waters, including wetlands, is also prohibited, unless authorized by a permit issued by the U.S. Army Corps of Engineers (the “Corps”). These laws and any implementing regulations provide for administrative, civil and criminal penalties for any unauthorized discharges of oil and other businesses or activities that might besubstances in direct competition with us exceptreportable quantities and may impose substantial potential liability for the costs of removal, remediation and damages. In September 2015, the EPA and the Corps issued a final rule defining the scope of the EPA’s and the Corps’ jurisdiction over waters of the U.S. (the “WOTUS rule”). However, on January 23, 2020, the EPA and the Corps finalized the Navigable Waters Protection Rule, which narrows the definition of “waters of the United States” relative to the extent they compete using our confidential information.

Our general partner hasprior 2015 rulemaking. Legal challenges to both this and prior revisions to the definition of WOTUS are ongoing, and it is possible that a call right that may require you to sell your common shares at an undesirable time or price.

As a result youof these developments, the scope of jurisdiction under the CWA is uncertain at this time. To the extent any rule expands the scope of the CWA’s jurisdiction in areas where we operate, we could face increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas. Separately, in April 2020, the federal district court for the District of Montana determined that the Corps Clean Water Act Section 404 Nationwide Permit 12 (“NWP 12”)

10

Table of Contents

failed to comply with consultation requirements under the federal Endangered Species Act. The district court vacated NWP 12 and enjoined the issuance of new authorizations for oil and gas pipeline projects. While the district court’s order has subsequently been limited pending appeal and NWP 12 authorizations remain available for certain oil and gas pipeline projects, we cannot predict the ultimate outcome of this case and its impacts to the Nationwide Permit program. Relatedly, in response to the vacatur, the Corps reissued NWP 12 for oil and natural gas pipeline activities, including certain revisions to the conditions for the use of NWP 12; however, the rulemaking may be subject to litigation or to further revision under the Biden Administration. While the full extent and impact of the vacatur is unclear at this time, any disruption in our ability to obtain coverage under NWP 12 or other general permits may result in increased costs and project delays if we are forced to seek individual permits from the Corps.

Pursuant to these laws and regulations, we may be required to sell your common shares at an undesirable timeobtain and maintain approvals or pricepermits for the discharge of wastewater or storm water and are required to develop and implement spill prevention, control and countermeasure plans, also referred to as “SPCC plans,” in connection with on-site storage of significant quantities of oil.

Tax Risks

As our only cash‑generating assets consists of our capital interest in IDR LLC and its related direct interests in Antero Midstream, our tax risks are primarily derivativesubject to the requirements of the tax risks associatedfederal Occupational Safety and Health Act, as amended (“OSHA”), and comparable state laws that regulate the protection of the health and safety of employees. In addition, OSHA’s hazard communication standard, the Emergency Planning and Community Right to Know Act and implementing regulations and similar state statutes and regulations require that information be maintained about hazardous materials used or produced in our operations and that this information be provided to employees, state and local government authorities and citizens. We do not believe that noncompliance with an investmentworker health and safety requirements will have a material adverse effect on our business or operations.

Endangered Species

The federal Endangered Species Act (“ESA”), provides for the protection of endangered and threatened species. Pursuant to the ESA, if a species is listed as threatened or endangered, restrictions may be imposed on activities adversely affecting that species’ habitat. Similar protections are offered to migratory birds under the Migratory Bird Treaty Act. We conduct operations and have pipeline construction and maintenance projects in Antero Midstream.

areas where certain species that are listed as threatened or endangered are known to exist and where other species that potentially could be listed as threatened or endangered under the ESA may exist. The tax treatmentU.S. Fish and Wildlife Service (the “USFWS”), may designate critical habitat and suitable habitat areas that it believes are necessary for survival of a threatened or endangered species. A critical habitat or suitable habitat designation could result in further material restrictions to federal land use and may materially delay or prohibit access to protected areas for natural gas and oil development. Moreover, as a result of a settlement, the USFWS was required to make a determination as to whether more than 250 species classified as endangered or threatened should be listed under the ESA by the completion of the agency’s 2017 fiscal year. For example, in April 2015, the USFWS listed the northern long-eared bat, whose habitat includes the areas in which we operate, as a threatened species under the ESA; however, on January 28, 2020, the U.S. District Court for the District of Columbia ordered the USFWS to reconsider its decision to list the northern long-eared bat as threatened instead of endangered. The designation of previously unprotected species as threatened or endangered, or redesignation of a threatened species as endangered, in areas where we conduct operations could cause us to incur increased costs arising from species protection measures or could result in limitations on our pipeline construction activities or the exploration and production activities of Antero Midstream dependsResources, any of which could have an adverse impact on its statusour results of operations.

Climate Change

In response to findings that emissions of greenhouse gases (“GHGs”) present an endangerment to public health and the environment, the EPA has adopted regulations under existing provisions of the federal Clean Air Act, that, among other things, establish Prevention of Significant Deterioration (“PSD”), pre-construction permits, and Title V operating permits for GHG emissions from certain large stationary sources that are already potential major sources of criteria pollutant emissions regulated under the statute. Under these regulations, facilities required to obtain PSD permits must meet BACT standards for their GHG emissions established by the states or, in some cases, by the EPA, for those emissions. The EPA has also adopted rules requiring the monitoring and reporting of GHG emissions from specified sources in the United States, including, among others, certain onshore oil and natural gas processing and fractionating facilities. In June 2016, the EPA finalized new regulations, known as Subpart OOOOa, that set emissions standards for methane and volatile organic compounds from new and modified oil and natural gas production and natural gas processing and transmission facilities. In September 2020, the EPA finalized amendments to the 2016 standards that removed the transmission and storage segment from the oil and natural gas source category and rescinded the methane-specific requirements for production and processing facilities. However, President Biden signed an executive order on his first day in office calling for the suspension, revision

11

Table of Contents

or rescission of the September 2020 rule and the reinstatement or issuance of methane emission standards for new, modified and existing oil and gas facilities. Given the long-term trend toward increasing regulation, future federal GHG regulations of the oil and gas industry remain a partnershippossibility, and several states have separately imposed their own regulations on methane emissions from oil and gas production activities. These rules (and any additional regulations) could impose new compliance costs and permitting burdens on natural gas operations.

In the United States, no comprehensive climate change legislation has been implemented at the federal level. However, governmental, scientific and public concern over the threat of climate change arising from GHG emissions has resulted in increasing political risks in the United States, including climate change related pledges made by President Biden and other public office representatives. These have included promises to pursue actions to limit emissions and curtail the production of oil and gas, such as through banning new leases for U.S.production of minerals on federal income tax purposes,properties, including onshore lands and offshore waters. On January 27, 2021, President Biden signed an executive order calling for substantial action on climate change, including among other things, the increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry, and increased emphasis on climate-related risks across agencies and economic sectors. Other actions that could be pursued by the Biden Administration may include the imposition of more restrictive requirements for the establishment of pipeline infrastructure or the permitting of LNG export facilities, as well as it not being subjectmore restrictive GHG emissions limitations for oil and gas facilities. Additionally, President Biden has issued executive orders recommitting the United States to a material amountthe Paris Agreement and directing the federal government to begin formulating the United States’ nationally determined emissions reduction target under the agreement. The impacts of entity‑level taxation. Ifthis order, and any legislation or regulation promulgated to fulfill the Internal Revenue Service (“IRS”) were to treat Antero MidstreamUnited States commitments under the Paris Agreement cannot be predicted at this time. Litigation risks are also increasing, as a corporationnumber of cities and other local governments have sought to bring suit against the largest oil and natural gas companies in state or federal court, alleging, among other things, that such companies created public nuisances by producing fuels that contributed to global warming effects and therefore are responsible for federal income tax purposesdamages as a result, or Antero Midstream were to become subject to additional amounts of entity‑level taxation for state tax purposes, it would reducealleging that the amount of cash available for distribution to us.

We own allcompanies have been aware of the adverse effects of climate change for some time but defrauded their investors or customers by failing to adequately disclose those impacts.

Additionally, our access to capital interestsmay be impacted by climate change policies. Financial institutions may adopt policies that have the effect of reducing the funding provided to the fossil fuel sector. For example, the Federal Reserve recently announced that it has joined the Network for Greening the Financial System, a consortium of financial regulators focused on addressing climate-related risks in IDR LLC, which directly owns all of the IDRs in Antero Midstream. Accordingly, the value of our investment in IDR LLC, as well as the anticipated after‑tax economic benefit of an investment in our common shares, depends largely on Antero Midstream being treated as a partnership for U.S. federal income tax purposes, which requires that at least 90% of Antero Midstream’s gross income for each taxable year of its existence consist of qualifying income, as that term is defined in Section 7704 of the Internal Revenue Code of 1986, as amended (the “Code”).

Despite the fact that Antero Midstream is a limited partnership under Delaware law and, unlike us, has not elected to be treated as a corporation for U.S. federal income tax purposes, it is possible, under certain circumstances, for Antero Midstream to be treated as a corporation for U.S. federal income tax purposes. Althoughfinancial sector. While we do not believe, based on its current operations, that Antero Midstream will be so treated, a change in Antero Midstream’s business could cause it to be treated as a corporation for U.S. federal income tax purposes. A change in current law could also cause Antero Midstream to be treated as a corporation for U.S. federal income tax purposes or otherwise subject Antero Midstream to entity‑level taxation. In addition, several states are evaluating ways to subject partnerships to entity‑level taxation through the imposition of state income, franchise and other forms of taxation.

If Antero Midstream were treated as a corporation for U.S. federal income tax purposes, it would pay federal income tax on its taxable income at the applicable corporate tax rate and would likely pay state income taxes at varying rates. Distributions to Antero Midstream’s partners, including IDR LLC, would generally be taxed again as corporate distributions, and no income, gains, losses or deductions would flow through to Antero Midstream’s partners. Because a tax would be imposed upon Antero Midstream as a corporation, its cash available for distribution would be substantially reduced. Therefore, treatment of Antero Midstream as a corporation wouldcannot predict what policies may result infrom this, a material reduction in the anticipated cash flows and after‑tax return to us, likely causing a substantial reduction in the value of our common shares.

Antero Midstream’s partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects Antero Midstream to taxation as a corporation or otherwise subjects Antero Midstream to entity‑level taxation for U.S. federal state or local income tax purposes, Antero Midstream’s minimum quarterly distribution and target distribution amounts may be adjusted to reflect the impact of that law or interpretation on Antero Midstream. If this were to happen, the amount of distributions IDR LLC receives from Antero Midstream and our resulting cash flows could be reduced substantially, which would adversely affect our ability to pay distributions.

The tax treatment of publicly traded partnerships such as Antero Midstream could be subject to potential legislative, judicial or administrative changes and differing interpretations, possibly applied on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, including Antero Midstream, may be modified by administrative, legislative or judicial changes, or differing interpretations at any time. From time to time, members of Congress propose and consider such substantive changescapital available to the existing U.S. federal income tax laws that affect publicly traded partnerships. Although there is no current legislative proposal, a prior legislative proposal would have eliminated 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.

In addition, on January 24, 2017, final regulations regarding which activities give rise to qualifying income within the meanings of Section 7704 of the Code (the “Final Regulations”) were published in the Federal Register. The Final Regulations are effective as of January 19, 2017, and apply to taxable years beginning on or after January 19. 2017. Antero Midstream does not believe the Final Regulations affect its ability to be treated as a partnership for U.S. federal income tax purposes.

However, any modification to the U.S. federal income tax laws may be applied retroactively andfossil fuel industry could make it more difficult or impossibleto secure funding for Antero Midstreamexploration, development, production, transportation and processing activities, which could result in decreased demand for our midstream services. Finally, it should be noted that a number of scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts and floods and other climatic events; if any such effects were to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes. Antero Midstreamoccur, it is unable to predict whetheruncertain if they would have an adverse effect on our financial condition and operations.

Although we have not experienced any of these changesmaterial adverse effect from compliance with environmental requirements, there is no assurance that this will continue. We did not have any material capital or other proposalsnon-recurring expenditures in connection with complying with environmental laws or environmental remediation matters in 2020, nor do we anticipate that such expenditures will be reintroduced or ultimately will be enacted. Any similar or future legislative changes could negatively impact the value of our indirect investmentmaterial in Antero Midstream.2021.

Employees are empowered and expected to stop or refuse to perform a job if it is not safe or cannot be performed safely. We sponsor emergency preparedness programs, conduct regular audits to assess our performance and celebrate our successes through the annual contractor safety conference where we acknowledge employees and contractors alike who have exhibited strong safety leadership during the course of the year. These many efforts combine to create a culture of safety throughout the company and provide a positive influence on our contractor community.

In response to the COVID-19 pandemic, we have implemented significant changes that we believe to be in the best interest of our employees, as well as the communities in which we operate, and that comply with government orders. These include having our office employees work from home to the extent they are able and implementing additional safety measures, including required weekly testing and other recommended public health measures, for our field and other employees continuing critical on-site work.

Diversity, Inclusion and Workplace Culture

We are committed to building a culture where diversity and inclusion are core philosophies across our operations, including, but not limited to, our decisions around recruitment, promotion, transfer, leaves of absence, compensation, opportunities for career support and advancement, job performance and other relevant job-related criteria. We embrace an approach to hiring and

advancement that considers the value of diversity, and we are also committed to making opportunities for development and progress available to all employees so their talents can be fully developed to maximize our and their success. We believe that creating an environment that cultivates a sense of belonging requires encouraging employees to continue to educate themselves about each other’s experiences, and we strive to promote the respect and dignity of all persons. We also believe it is important that we foster education, communication and understanding about diversity, inclusion and belonging. Finally, in line with our commitments to equal employment opportunity and diversity and inclusion, we expect recruiters operating on our behalf to provide us with a diverse pool of candidates.

Item 1A. Risk Factors

We are subject to certain risks and hazards due to the nature of the business activities we conduct. The risks described in this Annual Report on Form 10-K could materially and adversely affect our business, financial condition, cash flows and results of operations. We may experience additional risks and uncertainties not currently known to us. Furthermore, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect our business, financial condition, cash flows and results of operations.

Customer Concentration

Because substantially all of our revenue is currently derived from Antero Resources, any development that materially and adversely affects Antero Resources’ operations, financial condition or market reputation could have a material and adverse impact on us.

Antero Resources is our most significant customer and has accounted for substantially all of our revenue since inception, and we expect to derive most of our revenues from Antero Resources in the near term. As a result, any event, whether in our area of operations or otherwise, that adversely affects Antero Resources’ production, drilling and completion schedule, financial condition, leverage, market reputation, liquidity, results of operations or cash flows may adversely affect our business and results of operations. Accordingly, we are indirectly subject to the business risks of Antero Resources, including, among others:

a reduction in or slowing of Antero Resources’ development program, which would directly and adversely impact demand for our gathering and compression services and our water handling services;
a reduction in or slowing of Antero Resources’ well completions, which would directly and adversely impact demand for our water handling services;
the volatility of natural gas, NGLs and oil prices, which could have a negative effect on the value of Antero Resources’ properties, its development program and its ability to finance its operations;
the availability of capital on an economic basis to fund Antero Resources’ exploration and development activities and to service and/or refinance its debt, as well as to fund its capital expenditure programs;
Antero Resources’ ability to replace its oil and gas reserves;

14

Table of Contents

Antero Resources’ drilling and operating risks, including potential environmental liabilities;
transportation and processing capacity constraints and interruptions; and
adverse effects of governmental and environmental regulation.

Further, we are subject to the risk of non-payment or non-performance by Antero Resources, including with respect to our gathering and compression and water handling services agreements. We cannot predict the extent to which Antero Resources’ business would be impacted if conditions in the energy industry deteriorate, nor can we estimate the impact such conditions would have on Antero Resources’ ability to execute its drilling and development program or perform under our gathering and compression and water handling services agreements. 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 that any customer, including Antero Resources, 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 material non-payment or non-performance by Antero Resources could adversely affect our business and operating results.

Also, due to our relationship with Antero Resources, our ability to access the capital markets, or the pricing or other terms of any capital markets transactions, may be adversely affected by any impairment to Antero Resources’ financial condition or adverse changes in its credit ratings.

Any material limitation of our ability to access capital 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 Antero Resources could negatively impact our share price, limiting our ability to raise capital through equity issuances or debt financing, or could negatively affect our ability to engage in, expand or pursue our business activities and prevent us from engaging in certain transactions that might otherwise be considered beneficial to us.

Please see Item 1A, “Risk Factors” in Antero Resources’ Annual Report on Form 10-K for the year ended December 31, 2020 (which is not, and shall not be deemed to be, incorporated by reference herein) for a full disclosure of the risks associated with Antero Resources’ business.

Because of the natural decline in production from existing wells, our success depends, in part, on Antero Resources’ ability to replace declining production and our ability to secure new sources of natural gas from Antero Resources or third parties. Additionally, our water handling services are directly associated with Antero Resources’ well completion activities and water needs, which are largely driven by the amount of water used in completing each well. Finally, under certain circumstances, Antero Resources may dispose of acreage dedicated to us free from such dedication without our consent. Any decrease in volumes of natural gas that Antero Resources produces, any decrease in the number of wells that Antero Resources completes, or any decrease in the number of acres that are dedicated to us could adversely affect our business and operating results.

The natural gas volumes that support our gathering business depend on the level of production from wells connected to our systems, which may be less than expected and will naturally decline over time. To the extent Antero Resources reduces its development activity or otherwise ceases to drill and complete new wells, revenues for our gathering and compression and water handling services will be directly and adversely affected. Our ability to maintain water handling services revenues is substantially dependent on continued completion activity by Antero Resources or third parties over time, as well as the volumes of water used in and produced from such activity. In addition, natural gas volumes from completed wells will naturally decline and our cash flows associated with these wells will also decline over time. To maintain or increase throughput levels on our gathering systems, we must obtain new sources of natural gas from Antero Resources or third parties. The primary factors affecting our ability to obtain additional sources of natural gas include (i) the success of Antero Resources’ drilling activity in our areas of operation, (ii) Antero Resources’ ability to replace declining production, (iii) Antero Resources’ acquisition of additional acreage, including acquisitions that offset any dispositions by Antero Resources and (iv) our ability to obtain dedications of acreage from third parties. Demand for our fresh water delivery services, which make up a substantial portion of our water handling services revenues, is dependent on water used in Antero Resources’ completion activities. To the extent that Antero Resources or other fresh water delivery customers reduce the number of completion stages per well or use less water in their completions, the demand for our fresh water delivery services would be reduced.

We have no control over Antero Resources’ or other producers’ levels of development and completion activity in our areas of operation, the amount of oil and gas reserves associated with wells connected to our systems or the rate at which production from a well declines. In addition, our water handling business is dependent upon active development in our areas of operation. To maintain or increase throughput levels on our water handling systems, we must service new wells. We have no control over Antero Resources

or other producers or their development plan decisions, which are affected by, among other things:

the availability and cost of capital;
prevailing and projected natural gas, NGLs and oil prices;
demand for natural gas, NGLs and oil;
quantities of reserves;
geologic considerations;
environmental or other governmental regulations, including the availability of drilling permits and the regulation of hydraulic fracturing; and
the costs of producing the gas and the availability and costs of drilling rigs and other equipment.

The daily spot prices for NYMEX Henry Hub natural gas ranged from a high of $3.14 per MMBtu to a low of $1.33 per MMBtu in 2020, and the daily spot prices for NYMEX West Texas Intermediate crude oil ranged from a high of $63.27 per barrel to a low of $(36.98) per barrel during the same period. In addition, the market price for natural gas in the Appalachian Basin continues to be lower relative to NYMEX Henry Hub as a result of the significant increases in the supply of natural gas in the Northeast region in recent years. Because Antero Resources’ production and reserves predominantly consist of natural gas (approximately 57% of equivalent proved reserves), changes in natural gas prices have significantly greater impact on Antero Resources’ financial results than oil prices. NGLs are made up of ethane, propane, isobutane, normal butane and natural gasoline, all of which have different uses and different pricing characteristics, which adds further volatility to the pricing of NGLs. Due to the volatility of commodity prices, we are unable to predict future potential movements in the market prices for natural gas, oil and NGLs at Antero Resources’ ultimate sales points and, thus, cannot predict the ultimate impact of prices on our operations.

These lower prices have compelled most natural gas and oil producers, including Antero Resources, to reduce the level of exploration, drilling and production activity and capital budgets. For example, Antero Resources’ 2021 capital budget is $625 million, compared to 2019 and 2020 capital expenditures of $1.3 billion and $785 million, respectively. This will have a significant effect on our capital resources, liquidity and expected operating results. Natural gas and oil prices directly affect Antero Resources’ production. If prices remain at low levels or decrease further, our revenues, cash flows and results of operations could continue to be adversely affected. Sustained reductions in development or production activity in our areas of operation could lead to reduced utilization of our services and cash flows.

Due to these and other factors, even if reserves are known to exist in areas served by our assets, producers have chosen and may choose in the future, not to develop those reserves. Reductions in development activity, including Antero Resources’ reduction in lateral lengths or use of water in its completions, could result in our inability to maintain the current levels of throughput on our systems or reduce the demand for our water handling services on a per well basis, which could in turn reduce our revenue and cash flows and adversely affect our ability to return capital to our stockholders through dividends and/or repurchases of shares of our common stock.

Finally, each of the gathering and compression agreement, water services agreement and right of first offer agreement between us and Antero Resources permits Antero Resources to sell, transfer, convey, assign, grant or otherwise dispose of dedicated properties free of the dedication under such agreements, provided that the number of net acres of dedicated properties so disposed of, when added to the number of net acres of dedicated properties previously disposed of free of the dedication since the respective effective dates of the agreements, does not exceed the aggregate number of net acres of dedicated properties acquired by Antero Resources since such effective dates. Accordingly, under certain circumstances, Antero Resources may dispose of a significant number of net acres of dedicated properties free from dedication without our consent, and we have no control over the timing or extent of such dispositions. Any such dispositions could adversely affect our business and operating results. Even if the disposed property remains dedicated to us, the goals and intention of acquiror with respect to such property may differ significantly from those of Antero Resources.  For example, a subsequent owner of a property could choose to invest less capital in the development of such property or to otherwise drill fewer wells than Antero Resources.  There can be no assurance that a subsequent owner of dedicated properties would choose to, or be able to, grow or maintain current rates of production from the properties, which could adversely impact us.

Business Operations

A material shut-in of production by Antero Resources or any of our other customers could adversely affect our business.

The marketing of the natural gas, NGLs and oil of our producer customers is substantially dependent upon the existence ofadequate markets for their products. In response to the COVID-19 pandemic, governments have tried to slow the spread of the virus by imposing social distancing guidelines, travel restrictions and stay-at-home orders, which have caused a significant decrease in the demand for oil, natural gas and NGLs. The imbalance between the supply of and demand for these products, as well as the uncertainty around the extent and timing of an economic recovery, have caused extreme market volatility and a substantial adverse effect on commodity prices. Also as a result of this imbalance, the industry has experienced and may experience in the future storage capacity constraints with respect to oil and certain NGL products. If Antero Resources or any of our other customers are unable to sell their production or enter into additional storage arrangements on commercially reasonable terms or at all, they may be forced to temporarily shut in a portion of their production or delay or discontinue drilling and completion plans and commercial production. Although Antero Resources has not been required to temporarily shut-in a portion of its production, it may do so in the future. Production curtailments or shut-ins by our producer customers will reduce volumes flowing through our gathering and processing system. In addition, if our customers delay or discontinue drilling or completion activities, it will reduce the volumes of water that we handle. A material reduction in volumes on our systems could adversely affect our business, our revenue and cash flows and could adversely affect our ability to return capital to our stockholders through dividends and/or repurchases of shares of AM common stock.

The gathering and compression agreement includes minimum volume commitments only under certain circumstances.

The gathering and compression agreement includes minimum volume commitments only on new high pressure pipelines and compressor stations constructed subsequent to November 2014 at Antero Resources’ request. The high pressure pipelines and compressor stations that existed prior to November 2014 are not supported by minimum volume commitments from Antero Resources. There are no minimum volume commitments on the low pressure pipelines or fresh water distribution pipelines. Any decrease in the current levels of throughput on our gathering, compression and fresh water distribution systems could reduce our revenue and cash flows.

Our construction or purchase of new gathering and compression, processing, water handling or other assets may not be completed on schedule, at the budgeted cost or at all, may not operate as designed or at the expected levels, may not result in revenue increases and may be subject to regulatory, environmental, political, legal and economic risks, all of which could adversely affect our financial condition, cash flows and results of operations.

The construction of additions or modifications to our existing systems and the construction or purchase of new assets involves numerous regulatory, environmental, political and legal uncertainties beyond our control and may require the expenditure of significant amounts of capital. Financing may not be available on economically acceptable terms or at all. If we undertake these projects, we may not be able to complete them on schedule, at the budgeted cost or at all, or they may not operate as designed or at the expected levels. Moreover, our revenues may not increase immediately upon the expenditure of funds on a particular project. For example, the construction of our water treatment facility took longer than planned and the facility ran at operating rates below the designed capacity and did not meet certain completion milestones under the terms of the construction contract. As a result, in September 2019, we decided to idle such facility for the foreseeable future. Following such idling, we recorded aggregate non-cash impairment charges of approximately $463 million and expect to incur additional idling costs going forward. In addition, we may construct facilities to capture anticipated future production growth in an area in which such growth does not materialize. As a result, new gathering and compression, water handling or other assets may not be able to attract enough throughput to achieve our expected investment return, which could adversely affect our financial condition and results of operations. In addition, adding to our existing assets may require us to obtain new rights-of-way prior to constructing new pipelines or facilities. We may be unable to timely obtain such rights-of-way to connect new natural gas supplies to our existing gathering pipelines or capitalize on other attractive expansion opportunities. Additionally, it may become more expensive for us to obtain new rights-of-way or to expand or renew existing rights-of-way. If the cost of renewing or obtaining new rights-of-way increases, our cash flows could be adversely affected.

Recent action and the possibility of future action on trade by U.S. and foreign governments has increased the costs of certain equipment and materials used in the construction of our assets and has created uncertainty in global markets, which may adversely affect our income from operations and cash flows.

The construction of gathering pipelines, compressor stations, processing and fractionation facilities and water handling assets is subject to construction cost overruns due to costs and availability of equipment and materials such as steel.  If third party providers of steel products essential to our capital improvements and additions are unable to obtain raw materials, including steel, at historical prices, they may raise the price we pay for such products.  On March 8, 2018, the President of the United States issued two

17

Table of Contents

proclamations directing the imposition of ad valorem tariffs of 25% on certain imported steel products and 10% on certain imported aluminum products from most countries, with limited exceptions.  On May 31, 2018, the U.S. announced that it would also impose steel and aluminum tariffs on Canada, Mexico, and the 28 member countries of the European Union.  Argentina, Australia, Brazil and South Korea implemented measures to address the impairment to U.S. national security attributable to steel and/or aluminum imports that were deemed satisfactory to the United States.  On May 19, 2019, the U.S. announced that Canada and Mexico had also implemented satisfactory measures to address the threatened impairment to U.S. national security caused by steel and aluminum imports from those countries.  As a result, imports of steel from Argentina, Australia, Brazil, Canada, Mexico and South Korea and aluminum from Argentina, Australia, Canada and Mexico have been exempted from the imposition of tariff-based remedies, but the United States has implemented quantitative restrictions in the form of absolute quotas for steel article imports from Argentina, Brazil and South Korea and aluminum products from Argentina, meaning that imports in excess of the allotted quota will be disallowed.  In addition, effective August 13, 2018, the United States announced that it would impose a 50% ad valorem tariff on steel articles imported from Turkey, which remained in effect until May 21, 2019, at which time a 25% ad valorem tariff on steel articles imported from Turkey was reimposed, consistent with the tariff on imports from most countries. On January 24, 2020, the United States announced that an additional 25% ad valorem tariff would be imposed on certain derivative steel article imports from all countries except Argentina, Australia, Brazil, Canada, Mexico and South Korea, and that an additional 10% ad valorem tariff would be imposed on certain derivative aluminum article imports from all countries except Argentina, Australia, Canada and Mexico. On August 6, 2020, the U.S. re-imposed the 10% ad valorem tariff on imports of non-alloyed unwrought aluminum from Canada due to a surge in imports of those articles, but on October 27, 2020, retroactively reinstated Canada on the list of countries excluded from tariffs for those articles. On August 28, 2020, the U.S. announced that it would lower one of the quantitative limitations on imports of certain steel articles from Brazil for the remainder of 2020. The U.S. provided relief from these limitations in specific circumstances, namely for production activities with contracts for steel imports from Brazil during the fourth quarter of 2020 entered into before August 28, 2020 that met other specified criteria. In 2020, the U.S. and Mexico also engaged in discussions regarding steel imports pursuant to their Joint Statement of May 17, 2019. On August 31, 2020, the Office of the U.S. Trade Representative announced that Mexico would establish a strict monitoring regime of exports of standard pipe, mechanical tubing and semi-finished steel products to the U.S. through June 1, 2021. The U.S. agreed to continue to exempt Mexico from duty on these imports. On November 5, 2020, the Office of the U.S. Trade Representative announced that Mexico agreed to establish a strict monitoring regime for exports of certain grain-oriented electrical steel (“GOES”)-containing products into the U.S., and the U.S. agreed that Mexico would not be subject to any adjustments of imports of electrical transformers or related parts. In addition, the U.S.-Mexico-Canada Free Trade Agreement (“USMCA”) became effective on July 1, 2020. The USMCA includes agreements related to steel and aluminum imports, including changes to rules-of-origin requirements for steel and aluminum materials originating in North America, rules for determining whether goods containing materials from non-USMCA countries are considered “North American” under the Harmonized Tariff Schedule, and tariff exemptions for certain automotive imports. Following these proclamations, domestic prices for steel have risen and are expected to continue to rise.   These price increases may result in increased costs associated with the continued build-out of our assets, as well as projects under development. Because we generate substantially all of our revenue under agreements with Antero Resources that provide for fixed fee structures, we will generally be unable to pass these cost increases along to our customers, and our income from operations and cash flows may be adversely affected.

If third-party pipelines or other midstream facilities interconnected to our gathering and compression systems become partially or fully unavailable, our operating margin and cash flows could be adversely affected.

Our gathering and compression assets connect to other pipelines or facilities owned and operated by unaffiliated third parties. The continuing operation of third-party pipelines, compressor stations and other midstream facilities is not within our control. These pipelines, plants and other midstream facilities may become unavailable because of testing, turnarounds, line repair, maintenance, reduced operating pressure, lack of operating capacity, regulatory requirements and curtailments of receipt or deliveries due to insufficient capacity or because of damage from severe weather conditions or other operational issues. If any such increase in costs occurs or if any of these pipelines or other midstream facilities become unable to receive or transport natural gas, our operating margin and cash flows could be adversely affected.

Our exposure to commodity price risk may change over time.

We currently generate all of our revenues pursuant to fee-based contracts under which we are paid based on the volumes of natural gas that we gather, process and compress and water that we handle and treat, rather than the underlying value of the commodity. Consequently, our existing operations and cash flows have little direct exposure to commodity price risk. Although we intend to enter into similar fee-based contracts with new customers in the future, our efforts to negotiate such contractual terms may not be successful. In addition, we may acquire or develop additional midstream assets in a manner that increases our exposure to commodity price risk. Future exposure to the volatility of natural gas, NGL and oil prices, especially in light of the recent declines, could have a material adverse effect on our business, financial condition and results of operations.

Table of Contents

The fees charged to our customers may not escalate sufficiently to cover increases in costs, or the agreements may be amended with less favorable terms, may not be renewed or may be suspended in some circumstances.

Our costs may increase at a rate greater than the fees we charge to our customers. Furthermore, Antero Resources and our other customers may not renew their contracts with us, or may from time to time seek to renegotiate with us the amount and/or the structure of fees we charge. Additionally, some of our customers’ obligations under their agreements with us may be permanently or temporarily reduced due to certain events, some of which are beyond our control, including force majeure events wherein the supply of natural gas, NGLs, crude oil or refined products are curtailed or cut-off due to events beyond our control, and in some cases, certain of those agreements may be terminated in their entirety if the duration of such events exceeds a specified period of time. If the escalation of fees is insufficient to cover increased costs, or if our customers do not renew or extend their contracts with us, or if our customers suspend or terminate their contracts with us, our financial results would suffer.

Oil and natural gas producers’ operations, especially those using hydraulic fracturing, are substantially dependent on the availability of water. Restrictions on the ability to obtain water may incentivize water recycling efforts by oil and natural gas producers, which would decrease the demand for our fresh water delivery services.

Our business includes fresh water delivery for use in our customers’ natural gas, NGL and oil exploration and production activities. Water is an essential component of natural gas, NGL and oil production during the drilling, and in particular, the hydraulic fracturing process. We derive a significant portion of our revenues from providing fresh water to Antero Resources. Antero Resources implemented efficiency improvements and water initiatives during 2020, which reduced the amount of fresh water needed to complete their operations. These improvements allowed Antero Resources to reuse a portion of its produced water through our blending operations. Furthermore, the availability of water supply for our operations may be limited due to, among other things, prolonged drought or state and local governmental authorities restricting the use of water for hydraulic fracturing.  Any decrease in the demand for water handling services, or the water supply we need to provide such services, would adversely affect our business and results of operations.

Increasing attention to ESG matters and conservation measures may adversely impact our business.

Increasing attention to climate change, societal expectations on companies to address climate change, investor and societal expectations regarding voluntary ESG disclosures, and consumer demand for alternative forms of energy, may result in increased costs, reduced demand for our products, reduced profits, increased investigations and litigation, and negative impacts on our stock price and access to capital markets. Increasing attention to climate change and environmental conservation, for example, may result in demand shifts for oil and natural gas products and additional governmental investigations and private litigation against us or our customers, including Antero Resources. To the extent that societal pressures or political or other factors are involved, it is possible that such liability could be imposed without regard to our causation of or contribution to the asserted damage, or to other mitigating factors. 

Moreover, while we create and publish voluntary disclosures regarding ESG matters from time to time, many of the statements in those voluntary disclosures are based on hypothetical expectations and assumptions that may or may not be representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many ESG matters.    

In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating companies on their approach to ESG matters. Such ratings are used by some investors to inform their investment and voting decisions. Unfavorable ESG ratings and recent activism directed at shifting funding away from companies with energy-related assets could lead to increased negative investor sentiment toward us, Antero Resources, and our industry and to the diversion of investment to other industries, which could have a negative impact on our stock price and our access to and costs of capital. Also, institutional lenders may decide not to provide funding for fossil fuel energy companies or the corresponding infrastructure projects based on climate change related concerns, which could affect our access to capital for potential growth projects.

Our business involves many hazards and operational risks, some of which may not be fully covered by insurance. The occurrence of a significant accident or other event that is not fully insured could curtail our operations and have a material adverse effect on our business, financial condition and results of operations.

Our operations are subject to all of the hazards associated with the provision, gathering and compression of natural gas, NGLs and oil and water handling services, including:

19

Table of Contents

unintended breach of impoundment and downstream flooding, release of invasive species or aquatic pathogens, hazardous spills near intake points, trucking collision, vandalism, excessive road damage or bridge collapse and unauthorized access or use of automation controls;
damage to pipelines, compressor stations, pump stations, impoundments, related equipment and surrounding properties caused by natural disasters, acts of terrorism and acts of third parties;
damage from construction, farm and utility equipment as well as other subsurface activity (for example, mine subsidence);
leaks of natural gas, NGLs or oil or losses of natural gas, NGLs or oil as a result of the malfunction of equipment or facilities;
fires, ruptures and explosions;
other hazards that could also result in personal injury and loss of life, pollution of the environment, including natural resources and suspension of operations; and
hazards experienced by other operators that may affect our operations by instigating increased regulations and oversight.

Any of these risks could adversely affect our ability to conduct operations or result in substantial loss to us as a result of claims for:

injury or loss of life;
damage to and destruction of property, natural resources and equipment;
pollution and other environmental damage;
regulatory investigations and penalties;
suspension of our operations; and
repair and remediation costs.

We may elect not to obtain insurance for any or all of these risks if we believe that the cost of available insurance is excessive relative to the risks presented. In addition, pollution and environmental risks generally are not fully insurable under policies we are covered under, and we have obtained pollution insurance. The occurrence of an event that is not fully covered by insurance could have a material adverse effect on our business, financial condition and results of operations.

We do not own all of the land on which our pipelines and facilities are located, which could result in disruptions to our operations.

Because we do not own all of the land on which our pipelines and facilities have been constructed, we are subject to the possibility of more onerous terms or increased costs to retain necessary land use if we do not have valid rights-of-way or if such rights-of-way lapse or terminate. We obtain the rights to construct and operate our pipelines on land owned by third parties and governmental agencies for a specific period of time. Our loss of these rights, through our inability to renew right-of-way contracts or otherwise, could have a material adverse effect on our business, financial condition and results of operations.

A pandemic, epidemic or outbreak of an infectious disease, such as COVID-19, may materially adversely affect our business.

The global or national outbreak of an infectious disease, such as COVID-19, may cause disruptions to our business and operational plans, which may include (i) shortages of employees, (ii) unavailability of contractors and subcontractors, (iii) interruption of supplies from third parties upon which we rely, (iv) recommendations of, or restrictions imposed by, government and health authorities, including quarantines, to address the COVID-19 pandemic and (v) restrictions that we and our contractors and subcontractors impose, including facility shutdowns, to ensure the safety of employees and others. While it is not possible to predict their extent or durations, these disruptions may have a material adverse effect on our business, financial condition and results of

operations and could adversely affect our ability to return capital to our stockholders through dividends and/or repurchases of shares of AM common stock.

Further, adverse impacts on Antero Resources’business resulting from any such outbreak may also adversely affect our business and results of operations. For example, the effects of COVID-19 and concerns regarding its global spread have negatively impacted global demand for crude oil and natural gas, which could continue to contribute to price volatility impacting the price Antero Resources receives for its natural gas, NGLs and oil. In addition, COVID-19 could continue to materially and adversely affect the demand for and marketability of natural gas, NGLs and oil production and production levels. Although Antero Resources has not been required to curtail or shut-in a portion of its production, it may do so in the future. For further discussion of the business risks of Antero Resources that may impact us, see Customer ConcentrationBecause substantially all of our revenue is currently derived from Antero Resources, any development that materially and adversely affects Antero Resources’operations, financial condition or market reputation could have a material and adverse impact on us,” the effects of which may be heightened to the extent the COVID-19 pandemic adversely affects our business and financial results.

Terrorist or cyber-attacks and threats could have a material adverse effect on our business, financial condition and results of operations.

Terrorist or cyber-attacks may significantly affect the energy industry, including our operations and those of our suppliers and customers, as well as general economic conditions, consumer confidence and spending and market liquidity. Strategic targets, such as energy-related assets, may be at greater risk of future attacks than other targets in the United States. Our insurance may not protect us against such occurrences. We depend on digital technology in many areas of our business and operations, including, but not limited to, performing many of our gathering and compression and water handling services, recording financial and operating data, oversight and analysis of our operations and communications with the employees supporting our operations and our customers or service providers. Deliberate attacks on our assets or our Joint Venture’s assets, security breaches in our systems or infrastructure, or the systems or infrastructure of third-parties or the cloud, could lead to the corruption or loss of our proprietary and potentially sensitive data, delays in the performance of services for our customers, difficulty in completing and settling transactions, challenges in maintaining our books and records, environmental damage, communication interruptions or other operational disruptions and third-party liabilities. Cybersecurity attacks in particular are becoming more sophisticated and include, but are not limited to, malicious software, ransomware, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in critical systems, unauthorized release of confidential or otherwise protected information and corruption of data.

As cyber-attacks continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerabilities to cyber-attacks. In particular, our implementation of various procedures and controls to monitor and mitigate security threats and to increase security for our personnel, information, facilities and infrastructure may result in increased capital and operating costs. To date, we have not experienced any material losses relating to cyber-attacks; however, there can be no assurance that we will not suffer such losses in the future. Consequently, it is possible that any of these occurrences, or a combination of them, could have a material adverse effect on our business, financial condition and results of operations.

Capital Structure and Access to Capital

We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to satisfy our obligations under our indebtedness or to refinance, which may not be successful.

Our ability to make scheduled payments on, or to refinance, our indebtedness obligations, including our revolving credit facility and our senior notes, depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and certain financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, including the senior notes.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, sell assets, seek additional capital or restructure or refinance our indebtedness, including the senior notes. Our ability to restructure or refinance our indebtedness will depend on the condition of the capital markets, including the market for senior unsecured notes, and our financial condition at such time. Any refinancing of our indebtedness, including using borrowings under our revolving credit facility to redeem our senior notes, could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of existing or future debt instruments, including the indentures governing our senior notes, may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result

21

Table of Contents

in a reduction of our credit rating, which could harm our ability to incur additional indebtedness. In the absence of sufficient cash flows and capital resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. Our revolving credit facility and the indentures governing our senior notes place certain restrictions on our ability to dispose of assets and our use of the proceeds from such dispositions. We may not be able to consummate those dispositions, and the proceeds of any such disposition may not be adequate to meet any debt service obligations then due. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

We will be required to make capital expenditures to increase our asset base. If we cannot obtain needed capital or financing on satisfactory terms, we may be unable to expand our business operations and/or our financial leverage could increase.

To increase our asset base, we will need to make expansion capital expenditures. If we do not make sufficient or effective expansion capital expenditures, we may be unable to expand our business operations, which could adversely affect our business and operating results. To fund our expansion capital expenditures and investment capital expenditures, we expect to use cash from our operations or incur borrowings. Alternatively, we may sell additional shares of common stock or other securities to fund our capital expenditures. Our ability to obtain bank financing or our ability to access the capital markets for future equity or debt offerings may be limited by our or Antero Resources’ financial condition at the time of any such financing or offering and the covenants in our existing debt agreements, as well as by general economic conditions, contingencies and uncertainties that are beyond our control. In addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing shares of common stock may result in significant stockholder dilution. Neither Antero Resources or any of its affiliates is committed to providing any direct or indirect support to fund our growth.

We may be unable to access the equity or debt capital markets to meet our obligations. 

Declines in commodity prices or the financial condition or prospects of Antero Resources may cause the financial markets to exert downward pressure on our stock price and credit capacity.  For example, for portions of 2020, the market for senior unsecured notes was unfavorable for high-yield issuers such as us. Our plans for growth may require access to the capital and credit markets. Although the market for high-yield debt securities experienced periods of improvement in 2020, if the high-yield market deteriorates, or if we are unable to access alternative means of debt or equity financing on acceptable terms or at all, we may be unable to carry out our business plan, which could have a material adverse effect on our financial condition and results of operations and impair our ability to service our indebtedness.

Restrictions in our existing and future debt agreements could adversely affect our business, financial condition and results of operations.

Our revolving credit facility limits our ability to, among other things:

incur or guarantee additional debt;
redeem or repurchase units or make distributions under certain circumstances;
make certain investments and acquisitions;
incur certain liens or permit them to exist;
enter into certain types of transactions with affiliates;
merge or consolidate with another company; and
transfer, sell or otherwise dispose of assets.

The indentures governing our senior notes contains similar restrictive covenants. In addition, our revolving credit facility contains covenants requiring us to maintain certain financial ratios. Our ability to meet those financial ratios and tests can be affected by events beyond our control, and we cannot assure you that we will meet any such ratio or test. Additionally, we may not be able to borrow the full amount of commitments under our revolving credit facility if doing so would cause us to breach a financial covenant.

The provisions of our revolving credit facility and the indentures governing our senior notes 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 revolving credit facility or the indentures governing our senior notes could result in a default or an event of default that could enable our lenders or noteholders to declare the outstanding principal of

that debt, together with accrued and unpaid interest, to be immediately due and payable. If our obligations to repay our debt are accelerated, our assets may be insufficient to repay such debt in full, and you could experience a partial or total loss of your investment. Please read “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”

Debt we incur in the future may limit our flexibility to obtain financing and to pursue other business opportunities.

Our future level of debt could have important consequences to us, including the following:

our ability to obtain additional financing, if necessary, for working capital, capital expenditures (including required drilling pad connections and well connections pursuant to our gathering and compression agreements as well as acquisitions) or other purposes may be impaired or such financing may not be available on favorable terms;
our funds available for operations and future business opportunities will be reduced by that portion of our cash flows 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 any future indebtedness, we will be forced to take actions such as reducing or not paying dividends, reducing or delaying our business activities, investments or capital expenditures, selling assets or issuing equity. We may not be able to effect any of these actions on satisfactory terms or at all.

Increases in interest rates could adversely affect our business.

Our business and operating results can be harmed by factors such as the availability, terms of and cost of capital, increases in interest rates or a reduction in credit rating. These changes could cause our cost of doing business to increase, limit our ability to pursue growth opportunities, reduce cash flow used for our services and place us at a competitive disadvantage. For example, during 2020, we had average outstanding borrowings under our revolving credit facility of approximately $1.1 billion, and the impact of a 1.0% increase in interest rates on this amount of indebtedness would result in increased interest expense for that period of approximately $11 million and a corresponding decrease in our cash flows and net income before the effects of income taxes. Disruptions and volatility in the global financial markets may lead to a contraction in credit availability impacting our ability to finance our operations. A significant reduction in cash flows from operations or the availability of credit could materially and adversely affect our ability to carry out our business plan.

Geographic Concentration

Our gathering and compression and water handling systems are concentrated in the Appalachian Basin, making us vulnerable to risks associated with operating in one major geographic area.

We rely primarily on revenues generated from our gathering and compression and water handling systems, which are all located in the Appalachian Basin. As a result of this concentration, we may be disproportionately exposed to the impact of regional supply and demand factors, delays or interruptions of production from wells in this area caused by, and associated with, governmental regulation, state and local political activities, market limitations, availability of equipment and personnel or interruption of the compression, processing or transportation of natural gas, NGLs or oil.

A shortage of equipment and skilled labor in the Appalachian Basin could reduce equipment availability and labor productivity and increase labor costs, which could have a material adverse effect on our business and results of operations.

Gathering and compression and water handling services require special equipment and laborers skilled in multiple disciplines, such as equipment operators, mechanics and engineers, among others. If Antero Resources experiences shortages of skilled labor or there is a lack of necessary equipment in the Appalachian Basin in the future, our allocation of labor costs and overall productivity could be materially and adversely affected. If our allocation of labor prices increase or if Antero Resources experiences materially increased health and benefit costs for employees, our business and results of operations could be materially and adversely affected.

Acquisitions and Takeovers

We may be unable to make attractive acquisitions or successfully integrate acquired businesses, and any inability to do so may disrupt our business and hinder our ability to grow.

In the future, we may acquire businesses that complement or expand our current business. We may not be able to identify attractive acquisition opportunities. Even if we do identify attractive acquisition opportunities, we may not be able to complete the acquisition or do so on commercially acceptable terms.

The success of any completed acquisition will depend on our ability to effectively integrate the acquired business into our existing operations. The process of integrating acquired businesses may involve unforeseen difficulties and may require a disproportionate amount of our managerial and financial resources. In addition, possible future acquisitions may be larger and for purchase prices significantly higher than those paid for earlier acquisitions. No assurance can be given that we will be able to identify suitable acquisition opportunities, negotiate acceptable terms, obtain financing for acquisitions on acceptable terms or successfully acquire identified targets. Our failure to achieve consolidation savings, to successfully integrate the acquired businesses and assets into our existing operations or to minimize any unforeseen operational difficulties could have a material adverse effect on our business, financial condition and results of operations.

In addition, our agreements governing our debt impose certain limitations on our ability to enter into mergers or combination transactions. Our revolving credit facility and the indentures governing our senior notes also limit our ability to incur certain indebtedness, which could indirectly limit our ability to engage in acquisitions of businesses.

Our certificate of incorporation and bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or merger proposals, which may adversely affect the market price of our common stock.

Certain provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our stockholders. Among other things, our certificate of incorporation and bylaws:

provide advance notice procedures with regard to stockholder nominations of candidates for election as directors or other stockholder proposals to be brought before meetings of our stockholders, which may preclude our stockholders from bringing certain matters before our stockholders at an annual or special meeting;
provide our Board of Directors (the “Board”) the ability to authorize issuance of preferred stock in one or more classes or series, which makes it possible for our Board to issue, without stockholder approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us and which may have the effect of deterring hostile takeovers or delaying changes in control or management of us;
provide that the authorized number of directors may be changed only by resolution of our Board;
provide that, subject to the rights of holders of any series of preferred stock to elect directors or fill vacancies in respect of such directors as specified in the related preferred stock designation and the terms of that certain Stockholders’ Agreement, dated October 9, 2018, by and among Antero Midstream Corporation and certain of its stockholders named thereto (the “Stockholders’ Agreement”), all vacancies, including newly created directorships be filled by the affirmative vote of holders of a majority of directors then in office, even if less than a quorum, or by the sole remaining director, and will not be filled by our stockholders;
provide that, subject to the rights of the holders of any series of preferred stock to elect directors under specified circumstances, if any, and the terms of the Stockholders’ Agreement, any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of our stockholders and may not be effected by any consent in writing in lieu of a meeting of such stockholders;
provide for our Board to be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three-year terms;
provide that, subject to the rights of the holders of shares of any series of preferred stock, if any, to remove directors elected by such series of preferred stock pursuant to our certificate of incorporation (including any preferred stock designation thereunder) and the terms of the Stockholders’ Agreement, directors may be removed from office at any

time, only for cause and by the holders of a majority of the voting power of all outstanding voting shares entitled to vote generally in the election of directors;
provide that special meetings of our stockholders may only be called only by the Chief Executive Officer, the Chairman of our Board or our Board pursuant to a resolution adopted by a majority of the total number of directors that we would have if there were no vacancies;
provide that (i) the Sponsor Holders and their affiliates are permitted to participate (directly or indirectly) in venture capital and other direct investments in corporations, joint ventures, limited liability companies and other entities conducting business of any kind, nature or description, (ii) the Sponsor Holders and their affiliates are permitted to have interests in, participate with, aid and maintain seats on the boards of directors or similar governing bodies of any such investments, in each case that may, are or will be competitive with our business and the business of our subsidiaries or in the same or similar lines of business as us and our subsidiaries, or that could be suitable for us or our subsidiaries and (iii) we have, subject to limited exceptions, renounced, to the fullest extent permitted by law, any interest or expectancy in, or in being offered an opportunity to participate in, such corporate opportunities;
provide that the provisions of our certificate of incorporation can only be amended or repealed by the affirmative vote of the holders of at least 66 2/3% in voting power of the outstanding shares of our common stock entitled to vote thereon, voting together as a single class; provided, however, that so long as the Stockholders' Agreement remains in effect, no provision of our certificate of incorporation may be amended, altered or repealed in any manner that would be contrary to or inconsistent with the terms of the Stockholders’ Agreement, and no amendment to the Stockholders’ Agreement (regardless of whether such amendment modifies any provision of the Stockholders’ Agreement to which our certificate of incorporation is subject) will be deemed an amendment of our certificate of incorporation; and
provide that our bylaws can be altered or repealed by (a) our Board or (b) our stockholders upon the affirmative vote of holders of at least 66 2/3% of the voting power of our common stock outstanding and entitled to vote thereon, voting together as a single class. However, so long as the Stockholders’ Agreement remains in effect, our Board may not approve any amendment, alteration or repeal of any provision of our bylaws or the adoption of any new bylaw, that (a) would be contrary to or inconsistent with the terms of the Stockholders’ Agreement or (b) would amend, alter or repeal certain portions of our certificate of incorporation; provided, however, that so long as the Stockholders’ Agreement remains in effect, the parties to the Stockholders' Agreement may amend any provision of the Stockholders’ Agreement, and no amendment to the Stockholders’ Agreement (regardless of whether such amendment modifies any provision of the Stockholders’ Agreement to which the bylaws are subject) will be deemed an amendment of the bylaws for purposes of the amendment provisions of our bylaws.

We have elected not to be subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”), regulating corporate takeovers.

 In general, the provisions of Section 203 of the DGCL prohibit a Delaware corporation, including those whose securities are listed for trading on the New York Stock Exchange, from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

prior to such time, the business combination or the transaction which resulted in the stockholder becoming an interested stockholder is approved by our Board;
upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding certain specified shares); or
on or after such time the business combination is approved by our Board and authorized at a meeting of stockholders by the holders of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

Section 203 of the DGCL permits a Delaware corporation to elect not to be governed by the provisions of Section 203. Pursuant to our certificate of incorporation, we expressly elected not to be governed by Section 203. Accordingly, we are not subject to any anti-takeover effects or protections of Section 203 of the DGCL, although no assurance can be given that we will not elect to be governed by Section 203 of the DGCL pursuant to an amendment to our certificate of incorporation in the future.

Certain of our stockholders have investments in our affiliates that may conflict with the interests of other stockholders.

Certain funds affiliated with Yorktown Partners LLC (“Yorktown”), Paul M. Rady and Glen C. Warren, Jr. (collectively, the “Sponsors”) own a significant interest in us. Messrs. Rady and Warren and an individual affiliated with Yorktown serve as members of our Board and the board of directors of Antero Resources. The Sponsors also own a significant portion of the shares of common stock of Antero Resources. As a result of their investments in Antero Resources, the Sponsors may have conflicting interests with other stockholders. Conflicts of interest could arise in the future between us, on the one hand, and the Sponsors, on the other hand, regarding, among other things, decisions related to our financing, capital expenditures and growth plans, the terms of our agreements with Antero Resources and its subsidiaries and the pursuit of potentially competitive business activities or business opportunities.

Joint Ventures

We own a 50% interest in the Joint Venture, which is operated by MarkWest. While we have the ability to influence certain business decisions affecting the Joint Venture, the success of our investment in the Joint Venture will depend on MarkWest’s operation of the Joint Venture.

On February 6, 2017, we entered into the Joint Venture with MarkWest. While we and MarkWest each own a 50% interest in the Joint Venture, MarkWest is the primary operator of the Joint Venture, and we depend on MarkWest for the day-to-day operations of the Joint Venture. Our lack of control over the Joint Venture’s day-to-day operations and the associated costs of operations could result in receiving lower cash distributions from the Joint Venture than currently anticipated. In addition, differences in views among the owners of the Joint Venture could result in delayed decisions or in failures to agree on significant matters, potentially adversely affecting the business and results of operations or prospects of the Joint Venture and, in turn, the amount of cash from the Joint Venture operations distributed to us.

If the Joint Venture is not successful or if the Joint Venture does not perform as expected, our future financial performance may be negatively impacted.

We may be exposed to certain risks in connection with our ownership interest in the Joint Venture, including regulatory, environmental and litigation risks. If such risks or other anticipated or unanticipated liabilities were to materialize, any desired benefits of our entry into the Joint Venture may not be fully realized, if at all, and its future financial performance may be negatively impacted.

In addition, the Joint Venture may result in other difficulties including, among other things:

diversion of our management’s attention from other business concerns;
managing regulatory compliance and corporate governance matters;
an increase in our indebtedness; and
potential environmental or other regulatory compliance matters or liabilities and/or title issues, including certain liabilities arising from the operation of the Joint Venture assets prior to the closing of the Joint Venture.

Interruptions in operations at any of the Joint Venture’s facilities may adversely affect its operations and our gathering and processing and water handling operations.

The Joint Venture assets consist of processing plants in West Virginia and a one-third interest in two fractionators in Ohio (the “MarkWest fractionators”). Any significant interruption at these facilities would adversely affect the Joint Venture’s operations. Because a significant portion of Antero Resources’ production is processed by the Joint Venture, any significant interruption at these facilities would also adversely affect our midstream operations.

We do not operate the MarkWest fractionators, and the operations of the MarkWest’s and Joint Venture’s processing facilities and the MarkWest fractionators could be partially or completely shut down, temporarily or permanently, as the result of circumstances not within its control, such as:

unscheduled turnarounds or catastrophic events, including damages to facilities, related equipment and surrounding properties caused by earthquakes, tornadoes, hurricanes, floods, fires, severe weather, explosions and other natural disasters;

26

Table of Contents

restrictions imposed by governmental authorities or court proceedings;
labor difficulties that result in a work stoppage or slowdown;
a disruption in the supply of gas to MarkWest’s or the Joint Venture’s processing and fractionation plants and associated facilities;
disruption in the supply of power, water and other resources necessary to operate MarkWest’s or the Joint Venture’s facilities;
damage to MarkWest’s or the Joint Venture’s facilities resulting from gas that does not comply with applicable specifications; and
inadequate fractionation capacity or market access to support production volumes, including lack of availability of rail cars, barges, pipeline capacity or market constraints, including reduced demand or limited markets for certain NGL products.

In addition, MarkWest’s fractionation operations in the Appalachian Basin are integrated, and as a result, it is possible that an interruption of these operations in other regions may impact operations in the regions in which the Joint Venture’s facilities are located.

Compliance with Regulations

We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities.

Our operations are subject to complex and stringent federal, state and local laws and regulations. In order to conduct our operations in compliance with these laws and regulations, we must obtain and maintain numerous permits, approvals and certificates from various federal, state and local governmental authorities. We may incur substantial costs in order to maintain compliance with these existing laws and regulations and the permits and other approvals issued thereunder. In addition, our costs of compliance may increase or operational delays may occur if existing laws and regulations are revised or reinterpreted, or if new laws and regulations apply to our operations. Failure to comply with such laws and regulations, including any evolving interpretation and enforcement by governmental authorities, could have a material adverse effect on our business, financial condition and results of operations. Also, we might not be able to obtain or maintain all required environmental regulatory approvals for our operations. If there is a delay in obtaining any required environmental regulatory approvals, or if we fail to obtain and comply with them, the operation or construction of our facilities could be prevented or become subject to additional costs.

In addition, new or additional regulations, new interpretations of existing requirements or changes in our operations could also trigger the need for Environmental Assessments or more detailed Environmental Impact Statements under the National Environmental Policy Act and analogous state laws, or that impose new permitting requirements on our operations could result in increased costs or delays of, or denial of rights to conduct, our development programs. For example, in April 2020, the federal district court for the District of Montana determined that the Corps Clean Water Act Section 404 Nationwide NWP 12 failed to comply with consultation requirements under the federal Endangered Species Act. The district court vacated NWP 12 and enjoined the issuance of new authorizations for oil and gas pipeline projects. While the district court’s order has subsequently been limited pending appeal and NWP 12 authorizations remain available for certain oil and gas pipeline projects, we cannot predict the ultimate outcome of this case and its impacts to the nationwide permit program. Relatedly, in response to the vacatur, the Corps reissued NWP 12 for oil and natural gas pipeline activities, including certain revisions to the conditions for the use of NWP 12; however, the rulemaking may be subject to litigation or to further revision under the Biden Administration. While the full extent and impact of the vacatur is unclear at this time, any disruption in our ability to obtain coverage under NWP 12 or other general permits may result in increased costs and project delays if we are forced to seek individual permits from the Corps. This in turn could have an adverse effect on our business, financial condition and results of operation. Separately, in January 2020, EPA and the Corps issued a final rule under the Clean Water Act (“CWA”) revising the definition of waters of the United States (“WOTUS”); however, both this and prior revisions to the definition of WOTUS are currently subject to litigation, and it is possible that a new presidential administration could propose a broader interpretation of the CWA’s jurisdiction. As a result, the scope of the CWA’s jurisdiction is uncertain at this time. To the extent any rule expands the scope of the CWA’s jurisdiction, we could face increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas. Such potential regulations or litigation could increase our operating costs, reduce our liquidity, delay or halt our operations or otherwise alter the way we conduct our business, which could in turn have a material adverse

27

effect on our business, financial condition and results of operations. Further, the discharges of natural gas, NGLs, oil and other pollutants into the air, soil or water may give rise to significant liabilities on our part to the government and third parties. Please read “Item 1. Business—Regulation of Environmental and Occupational Safety and Health Matters” for a further description of laws and regulations that affect us.

If our assets become subject to FERC regulation or federal, state or local regulations or policies change, or if we fail to comply with market behavior rules, our financial condition, cash flows and results of operations could be materially and adversely affected.

Our gathering and transportation operations are exempt from regulation by the FERC, under the NGA. Section 1(b) of the NGA, exempts natural gas gathering facilities from regulation by the FERC under the NGA. Although the FERC has not made any formal determinations with respect to any of our facilities, we believe that the natural gas pipelines in our gathering systems meet the traditional tests the FERC has used to establish whether a pipeline is a gathering pipeline not subject to FERC jurisdiction. The distinction between FERC-regulated transmission services and federally unregulated gathering services, however, has been the subject of substantial litigation, and the FERC determines whether facilities are gathering facilities on a case-by-case basis, so the classification and regulation of our gathering facilities may be subject to change based on future determinations by the FERC, the courts or Congress. If the FERC were to consider the status of an individual facility and determine that the facility or services provided by it are not exempt from FERC regulation under the NGA, the rates for, and terms and conditions of, services provided by such facility would be subject to regulation by the FERC under the NGA or the NGPA. Such regulation could decrease revenue, increase operating costs, and, depending upon the facility in question, could adversely affect our financial condition, cash flows and results of operations.

State regulation of natural gas gathering facilities and intrastate transportation pipelines generally includes various safety, environmental and, in some circumstances, nondiscriminatory take and common purchaser requirements, as well as complaint-based rate regulation. Other state regulations may not directly apply to our business, but may nonetheless affect the availability of natural gas for purchase, compression and sale.

Moreover, FERC regulations indirectly impact our businesses and the markets for products derived from these businesses. The FERC’s policies and practices across the range of its natural gas regulatory activities, including, for example, its policies on open access transportation, market manipulation, ratemaking, gas quality, capacity release and market center promotion, indirectly affect the intrastate natural gas market. Should we fail to comply with any applicable FERC administered statutes, rules, regulations and orders, we could be subject to substantial penalties and fines, which could have a material adverse effect on our financial condition, cash flows and results of operations. The FERC has civil penalty authority under the NGA and NGPA to impose penalties for current violations of up to $1,307,164 per day for each violation and disgorgement of profits associated with any violation.

For more information regarding federal and state regulation of our operations, please read “Business—Regulation of Operations.”

Increased regulation of hydraulic fracturing could result in reductions or delays in production by our customers, which could reduce the throughput on our gathering and processing systems and the number of wells for which we provide water handling services, which could adversely impact our revenues.

All of Antero Resources’ natural gas, NGLs and oil production is developed from unconventional sources, such as shale formations. These reservoirs require hydraulic fracturing completion processes to release the liquids and natural gas from the rock so it can flow through casing to the surface. Hydraulic fracturing is a well stimulation process that utilizes large volumes of water and sand (or other proppant) combined with fracturing chemical additives that are pumped at high pressure to crack open previously impenetrable rock to release hydrocarbons. Hydraulic fracturing is typically regulated by state oil and gas commissions and similar agencies, but the EPA has asserted federal regulatory authority pursuant to the SDWA over certain hydraulic fracturing activities involving the use of diesel fuels and issued permitting guidance in February 2014 regarding such activities. In addition, the EPA finalized rules in June 2016 that prohibit the discharge of wastewater from hydraulic fracturing operations to publicly owned wastewater treatment plants.

In addition, Congress has from time to time considered legislation to provide for federal regulation of hydraulic fracturing under the SDWA and to require disclosure of the chemicals used in the hydraulic fracturing process. New legislation regulating hydraulic fracturing may be considered again in future, though we cannot predict when or the scope of any such legislation at this time. At the state level, several states have adopted or are considering legal requirements that could impose more stringent permitting, disclosure and well construction requirements on hydraulic fracturing activities. At the state level, several states have adopted or are considering adopting regulations that could impose more stringent disclosure and/or well construction requirements on hydraulic

fracturing operations. For example, in July 2015, the Ohio Department of Natural Resources issued final rules for horizontal drilling well-pad construction. The Ohio legislature has also adopted laws requiring oil and natural gas operators to disclose chemical ingredients used to hydraulically fracture wells and to conduct pre-drilling baseline water quality sampling of certain water wells near a proposed horizontal well. Local governments also may seek to adopt ordinances within their jurisdictions regulating the time, place and manner of drilling activities in general or hydraulic fracturing activities in particular.

We cannot predict whether any such legislation will ever be enacted and if so, what its provisions would be. If additional levels of regulation and permits were required through the adoption of new laws and regulations at the federal, state or local level, that could lead to delays, increased operating costs and process prohibitions that could reduce the amount of natural gas that moves through our gathering and processing systems or reduce the number of wells drilled and completed that require fresh water for hydraulic fracturing activities, which in turn could materially and adversely affect our revenues and results of operations.

We or any third-party customers may incur significant liability under, or costs and expenditures to comply with, environmental and occupational health and workplace safety regulations, which are complex and subject to frequent change.

As an owner, lessee or operator of gathering pipelines and compressor stations, we are subject to various stringent federal, state, provincial and local laws and regulations relating to the discharge of materials into, and protection of, the environment. Numerous governmental authorities, such as the EPA and analogous state agencies, have the power to enforce compliance with these laws and regulations and the permits issued under them, oftentimes requiring difficult and costly response actions. These laws and regulations may impose various obligations that are applicable to our and our customer’s operations, including the acquisition of permits to conduct regulated activities, the incurrence of capital or operating expenditures to limit or prevent releases of materials from our or our customers’ operations, the imposition of specific standards addressing worker protection, and the imposition of substantial liabilities and remedial obligations for pollution or contamination resulting from our and our customer’s operations. Failure to comply with these laws, regulations and permits may result in joint and several, strict liability and the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations and the issuance of injunctions limiting or preventing some or all of our operations. Private parties, including the owners of the properties through which our gathering systems pass and facilities where wastes resulting from our operations are taken for reclamation or disposal, may also have the right to pursue legal actions to enforce compliance, as well as to seek damages for non-compliance, with environmental laws and regulations or for personal injury or property damage. We may not be able to recover all or any of these costs from insurance. In addition, we may experience a delay in obtaining or be unable to obtain required permits, which may cause us to lose potential and current customers, interrupt our operations and limit our growth and revenues, which in turn could affect our profitability. There is no assurance that changes in or additions to public policy regarding the protection of the environment will not have a significant impact on our operations and profitability. For example, following the election of President Biden and a Democratic majority in both houses of Congress, it is possible that our operations and those of our clients, may be subject to greater environmental, health and safety restrictions, particularly with regards to hydraulic fracturing, permitting and GHG emissions.

Our operations also pose risks of environmental liability due to potential leakage, migration, releases or spills from our operations to surface or subsurface soils, surface water or groundwater. Certain environmental laws impose strict as well as joint and several liability for costs required to remediate and restore sites where hazardous substances, hydrocarbons or solid wastes have been stored or released. We may be required to remediate contaminated properties currently or formerly operated by us or facilities of third parties that received waste generated by our operations regardless of whether such contamination resulted from the conduct of others or from consequences of our own actions that were in compliance with all applicable laws at the time those actions were taken. In addition, claims for damages to persons or property, including natural resources, may result from the environmental, health and safety impacts of our operations. Moreover, public interest in the protection of the environment has increased dramatically in recent years. The trend of more expansive and stringent environmental legislation and regulations is expected to continue, which may result in increased costs of doing business and consequently affecting profitability. Please read “Business—Regulation of Environmental and Occupational Safety and Health Matters” for more information.

Our operations are subject to a series of risks related to climate change that could result in increased operating costs, limit the areas in which our customers may conduct oil and gas exploration and production activities, and reduce demand for the services we provide.

The threat of climate change continues to attract considerable attention in the United States and in foreign countries. In the United States, no comprehensive climate change legislation has been implemented at the federal level. However, President Biden has highlighted addressing climate change as a priority of his administration, which includes certain potential initiatives for climate change legislation to be proposed and passed into law. Moreover, federal regulators, state and local governments and private parties have taken (or announced that they plan to take) actions that have or may have a significant influence on our operations. For example, in response to findings that emissions of carbon dioxide, methane and other GHGs endanger public health and the environment, the

Table of Contents

EPA has adopted regulations under existing provisions of the federal Clean Air Act that, among other things, establish PSD construction and Title V operating permit reviews for certain large stationary sources that are already potential major sources of certain principal, or criteria, pollutant emissions. Facilities required to obtain PSD permits for their GHG emissions also will be required to meet “best available control technology” standards that will be established by the states or, in some cases, by the EPA for those emissions. These EPA rules could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources. In addition, the EPA has adopted rules requiring the monitoring and reporting of GHG emissions from specified onshore and offshore oil and gas production sources in the United States on an annual basis, which include certain of our operations.

In June 2016, the EPA finalized new regulations, known as Subpart OOOOa, that establish emission standards for methane and volatile organic compounds from new and modified oil and natural gas production and natural gas processing and transmission facilities. The EPA’s rule package included first-time standards to address emissions of methane from equipment and processes across the source category, including hydraulically fractured oil and natural gas well completions. In addition, the rule package extended existing VOC standards under the EPA’s Subpart OOOO to include previously unregulated equipment within the oil and natural gas source category. In September 2020, the EPA finalized amendments to the 2016 standards that removed the transmission and storage segment from the oil and natural gas source category and rescinded the methane-specific requirements for production and processing facilities. However, President Biden signed an executive order on his first day in office calling for the suspension, revision or rescission of the September 2020 rule and the reinstatement or issuance of methane emission standards for new, modified and existing oil and gas facilities. Given the long-term trend toward increasing regulation, future federal GHG regulations of the oil and gas industry remain a possibility, and several states, including West Virginia and Ohio, have separately imposed their own regulations on methane emissions from oil and gas production activities.

Internationally, the United Nations-sponsored “Paris Agreement” requires member states to individually determine and submit non-binding emissions reduction targets every five years after 2020. Although the United States had withdrawn from the Paris Agreement, effective January 20, 2021, President Biden has issued executive orders recommitting the United States to the Paris Agreement and directing the federal government to begin formulating the United States’ nationally determined emissions reduction target under the Paris Agreement. The impacts of this order, and any legislation or regulation promulgated to fulfill the United States commitments under the Paris Agreement cannot be predicted at this time.

Concern over the threat of climate change has also resulted in increasing political risks in the United States, including climate-change related pledges made by President Biden and other public office representatives. These have included promises to pursue actions to limit emissions and curtail the production of oil and gas, such as through the cessation of leasing public land for hydrocarbon development. On January 27, 2021, President Biden signed an executive order calling for substantial action on climate change, including among other things, the increased use of zero-emissions vehicles by the federal government, the elimination of subsidies provided to the fossil fuel industry, and increased emphasis on climate-related risks across agencies and economic sectors. Other actions that could be pursued by the Biden administration include more restrictive requirements for the development of pipeline infrastructure or LNG export facilities, as well as more restrictive GHG emissions limitations for oil and gas facilities.

Increasingly, fossil fuel companies are also exposed to litigation risks from climate change. A number of cities and other local governments have brought suits against the largest fossil fuel companies in state or federal court, alleging, among other things, that such companies created public nuisances by producing fuels that contributed to climate change. Suits have also been brought against such companies under shareholder and consumer protection laws, alleging that the companies have been aware of the adverse effects of climate change but failed to adequately disclose those impacts. While we are not currently party to any such litigation, we could be named in future actions making similar claims of liability. Moreover, to the extent that societal pressures or political or other factors are involved, it is possible that such liability could be imposed without regard to the company’s causation of or contribution to the asserted damage, or to other mitigating factors.

Additionally, in response to concerns related to climate change, companies in the fossil fuel sector may be exposed to increasing financial risks. Financial institutions, including investment advisors and certain sovereign wealth, pension and endowment funds, may elect in the future to shift some or all of their investment into non-fossil fuel related sectors. Institutional lenders who provide financing to fossil-fuel energy companies have also become more attentive to sustainable lending practices, and some of them may elect in future not to provide funding for fossil fuel energy companies. There is also a risk that financial institutions will be required to adopt policies that have the effect of reducing the funding provided to the fossil fuel sector. Recently, the Federal Reserve announced that it has joined the Network for Greening the Financial System, a consortium of financial regulators focused on addressing climate-related risks in the financial sector. A material reduction in the capital available to the fossil fuel industry could make it more difficult to secure funding for exploration, development, production, transportation and processing activities, which could result in decreased demand for our midstream services.

The adoption and implementation of new or more stringent international, federal or state legislation, regulations or other

30

Table of Contents

regulatory initiatives related to climate change or GHG emissions from oil and natural gas facilities could result in increased costs of compliance or costs of consumption, thereby reducing demand for the services we provide. Additionally, political, litigation and financial risks may result in our restricting or cancelling oil and natural gas production activities, incurring liability for damages resulting from climate change or impairing our ability to continue operating in an economic manner. One or more of these developments could have a material adverse effect on our business, financial condition and results of operation. Finally, it should be noted that a number of scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, floods, droughts and other extreme climatic events; if any such effects were to occur, they have the potential to cause physical damage to our assets or affect the availability of water and thus could have an adverse effect on exploration and production operations. In addition, while our consideration of changing weather conditions and inclusion of safety factors in design covers the uncertainties that climate change and other events may potentially introduce, our ability to mitigate the adverse impacts of these events depends in part on the effectiveness of our facilities and our disaster preparedness and response and business continuity planning, which may not have considered or be prepared for every eventuality.

We may incur significant costs and liabilities as a result of pipeline integrity management program testing and any related pipeline repair or preventative or remedial measures.

The DOT has adopted regulations requiring pipeline operators to develop integrity management programs for transportation pipelines located where a leak or rupture could do the most harm in HCAs. The regulations require operators to:

perform ongoing assessments of pipeline integrity;
identify and characterize applicable threats to pipeline segments that could impact an HCA;
improve data collection, integration and analysis;
repair and remediate the pipeline as necessary; and
implement preventive and mitigating actions.

The Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011 (the “2011 Pipeline Safety Act”), among other things, increased the maximum civil penalty for pipeline safety violations and directed the Secretary of Transportation to promulgate rules or standards relating to expanded integrity management requirements, automatic or remote-controlled valve use, excess flow valve use, leak detection system installation and testing to confirm the material strength of pipe operating above 30% of specified minimum yield strength in HCAs. Consistent with the 2011 Pipeline Safety Act, the Pipelines and Hazardous Materials Safety Administration (“PHMSA”), finalized rules consistent with the signed act that increased the maximum administrative civil penalties for violations of the pipeline safety laws and regulations to $200,000 per violation per day, with a maximum of $2,000,000 for a related series of violations. In July 2019, those maximum civil penalties were increased to $218,647 and $2,186,465, respectively, to account for inflation. Should our operations fail to comply with DOT or comparable state regulations, we could be subject to substantial penalties and fines.

In June 2016, the President of the United States signed into law important new legislation entitled Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2016 (the “PIPES Act”). The PIPES Act facilitates greater pipeline safety by providing PHMSA with emergency order authority, including authority to issue prohibitions and safety measures on owners and operators of gas or hazardous liquid pipeline facilities to address imminent hazards, without prior notice or an opportunity for a hearing, as well as enhanced release reporting requirements, requiring a review of both natural gas and hazardous liquid integrity management programs, and mandating the creation of a working group to consider the development of an information-sharing system related to integrity risk analyses. The PIPES Act also requires that PHMSA publish periodic updates on the status of those mandates outstanding from 2011 Pipeline Safety Act, of which several remain to be completed.

PHMSA regularly revises its pipeline safety regulations. For example, in October 2019, PHMSA published three final rules on pipeline safety. The Enhanced Emergency Order Procedures rule (effective December 2, 2019) implements an existing statutory authorization for PHMSA to issue emergency orders related to pipeline safety if unsafe conditions or practices, or a combination thereof, constitutes or causes an imminent hazard.  The Safety of Hazardous Liquid Pipelines rule (effective July 1, 2020) expands PHMSA’s regulation of the safety of hazardous liquid pipelines by extending reporting requirements to certain hazardous liquid gravity flow and rural gathering pipelines, establishing new requirements for integrity management programs for hazardous liquid pipelines in HCAs and certain other hazardous liquid pipelines, and expanding various inspection and leak detection requirements.  The Safety of Gas Transmission Pipelines rule (effective July 1, 2020) requires operators of certain gas transmission

31

Table of Contents

pipelines to reconfirm the Maximum Allowable Operating Pressure (MAOP) of their lines and establishes a new “Moderate Consequence Area” for determining regulatory requirements for gas transmission pipeline segments outside of HCAs. The rule also establishes new requirements for conducting baseline assessments and incorporates industry standards and guidelines as well as new requirements for integrity management programs. The rule also includes several requirements that allow operators to notify PHMSA of proposed alternative approaches to achieving the objectives of the minimum safety standards.  We are in the process of assessing the impact of these rules on our future costs of operations and revenue from operations, but we do not expect our operations to be affected by these new rules any differently than other similarly situated midstream companies.

PHMSA is working on two additional rules related to gas pipeline safety, though we cannot predict when they will be finalized.  The rule entitled “Pipeline Safety: Safety of Gas Transmission Pipelines, Repair Criteria, Integrity Management Improvements, Cathodic Protection, Management of Change, and Other Related Amendments” is expected to adjust the repair criteria for pipelines in HCAs, create new criteria for pipelines in non-HCAs and strengthen integrity management assessment requirements. The rule entitled “Safety of Gas Gathering Pipelines” is expected to require all gas gathering pipeline operators to report incidents and annual pipeline data and to extend regulatory safety requirements to certain gas gathering pipelines in rural areas. The adoption of these and other laws or regulations that apply more comprehensive or stringent safety standards could require us to install new or modified safety controls, pursue new capital projects or conduct maintenance programs on an accelerated basis, all of which could require us to incur increased operational costs that could be significant, consistent with other similarly situated midstream companies. While we cannot predict the outcome of legislative or regulatory initiatives, such legislative and regulatory changes could have a material litigation.effect on our cash flow. Please read “Business—Pipeline Safety Regulation” for more information.

Human Capital

The loss of senior management or technical personnel could adversely affect operations.

We depend on the services of a relatively small group of senior management and technical personnel. We do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals. The loss of the services of our senior management or technical personnel, including Paul M. Rady, Chairman and Chief Executive Officer, and Glen C. Warren, Jr., President, could have a material adverse effect on our business, financial condition and results of operations.

Our officers and employees provide services to both Antero Resources and us.

All of our executive officers and certain other personnel who provide corporate, general and administrative services to our business are, when providing services to us, concurrently employed by Antero Resources and us pursuant to the terms of a services agreement. In addition, our operational personnel are seconded to us by Antero Resources pursuant to the terms of a secondment agreement and are concurrently employed by Antero Resources and us during such secondment. As a result, there could be material competition for the time and effort of the officers and employees who provide services to Antero Resources and us. If such officers and employees do not devote sufficient attention to the management and operation of our business, our financial results may suffer.

Related Parties

Antero Resources owns a significant interest in us and, as a result, conflicts of interest will arise from time to time between it and us, and Antero Resources may favor their own interests to the detriment of us and our other stockholders. Additionally, Antero Resources is under no obligation to adopt a business strategy that favors us.

All of our officers and certain of our directors are also officers or directors of Antero Resources. Also, as of December 31, 2020, Antero Resources beneficially owned 29.2% of our outstanding common stock. Our directors and officers who are also directors and officers of Antero Resources have a fiduciary duty to manage Antero Resources in a manner that is beneficial to Antero Resources. Conflicts of interest will arise between Antero Resources and us. In resolving these actual or apparent conflicts of interest, members of our Board may choose strategies that favor Antero Resources over our interests and the interests of our stockholders. These conflicts include, for example, the decision to declare and pay dividends or the decision to repurchase shares of our common stock owned by Antero Resources. The resolution of any conflicts of interest between Antero Resources and its subsidiaries, on one hand, and us and our subsidiaries, on the other, to the extent we can resolve them, may be costly and reduce the amount of time and attention that our directors and officers may spend in operating our business, which, in each case, may adversely affect our business.

Furthermore, Antero Resources is under no obligation to adopt a business strategy that favors us. For example, Antero Resources has dedicated acreage to, and entered into long-term contracts for gathering and compression services on, our gathering and compression systems, as well as long-term contracts for receiving water services.  However, while we have a right of first offer that

32

Table of Contents

expires in 2038 to provide processing and fractionation services to Antero Resources, subject to certain exceptions, Antero Resources is under no obligation to consider whether any future drilling plans would create beneficial opportunities for us.  Additionally, although our the processing and fractionation services provided by the Joint Venture are supported by minimum volume commitments, the gathering and compression agreement includes minimum volumes commitments only on high pressure pipelines and compressor stations constructed at Antero Resources’ request after November 2014.  Any decision by Antero Resources to operate its assets in a manner that does not support our operations could have a material adverse effect on our business, financial condition and results of operations.

We are a holding company whose sole material asset is our equity interest in Antero Midstream Partners, and we are accordingly dependent upon distributions from Antero Midstream Partners to pay taxes, return capital to stockholders and cover our corporate and other overhead expenses.

We are a holding company and have no material assets other than our equity interest in Antero Midstream Partners. We have no independent means of generating revenue. To the extent Antero Midstream Partners has available cash, we intend to cause Antero Midstream Partners to make distributions to us in an amount at least sufficient to allow us to pay our taxes, to fund our return of capital to our stockholders, including paying dividends and repurchasing shares of our common stock and for our corporate and other overhead expenses. To the extent that we need funds and Antero Midstream Partners or its subsidiaries are restricted from making such distributions or payments under applicable law or regulation or under the terms of any financing arrangements, or are otherwise unable to provide such funds, our liquidity and financial condition could be materially adversely affected.

Income Taxes

Our future tax liability may be greater than expected if we do not generate deductions or net operating loss (“NOL”) carryforwards sufficient to offset taxable income or if tax authorities challenge certain of our tax positions.

We expect to generate deductions and NOL carryforwards that we can use to offset our taxable income. As a result, we do not expect to pay material U.S. federal and state income taxes through 2023. This expectation is based upon assumptions our management has made regarding, among other things, income, capital expenditures and net working capital. Further, the IRS or other tax authorities could challenge one or more tax positions we take, such as the classification of assets under the income tax depreciation rules, the characterization of expenses for income tax purposes, and the tax characterization of the Transactions. Further, any change in law may affect our tax position. While we expect that our deductions and NOL carryforwards will be available to us as a future benefit, in the event that they are not generated as expected, are successfully challenged by the IRS (in a tax audit or otherwise), or are subject to future limitations, our ability to realize these benefits may be limited.

Taxable gain or loss on the sale of our common stock could be more or less than expected.

If a holder sells our common stock, the holder will recognize gain or loss equal to the difference between the amount realized and the holder’s tax basis in the shares of common stock sold. To the extent that the amount of distributions on our common stock exceeds our current and accumulated earnings and profits, such distributions will be treated as a tax free return of capital and will reduce a holder’s tax basis in its common stock. We expect the majority of our distributions to be in excess of our earnings and profits through 2023. Because our distributions in excess of our earnings and profits decrease a holder’s tax basis in our common stock, such excess distributions will result in a corresponding increase in the amount of gain, or a corresponding decrease in the amount of loss, recognized by the holder upon the sale of our common stock.

The IRS Forms 1099-DIV that our stockholders receive from their brokers may over-report dividend income with respect to our common stock for U.S. federal income tax purposes, which may result in a stockholder’s overpayment of tax. In addition, failure to report dividend income in a manner consistent with the IRS Forms 1099-DIV may cause the IRS to assert audit adjustments to a stockholder’s U.S. federal income tax return. For non-U.S. holders of our common stock, brokers or other withholding agents may overwithhold taxes from dividends paid, in which case a stockholder generally would have to timely file a U.S. tax return or an appropriate claim for refund to claim a refund of the overwithheld taxes.

Distributions we pay with respect to our common stock will constitute “dividends” for U.S. federal income tax purposes only to the extent of our current and accumulated earnings and profits. Distributions we pay in excess of our earnings and profits will not be treated as “dividends” for U.S. federal income tax purposes; instead, they will be treated first as a tax-free return of capital to the extent of a stockholder’s tax basis in their common stock and then as capital gain realized on the sale or exchange of such stock. We may be unable to timely determine the portion of our distributions that is a “dividend” for U.S. federal income tax purposes, which may result in a stockholder’s overpayment of tax with respect to distribution amounts that should have been classified as a tax-free return of capital. In such a case, a stockholder generally would have to timely file an amended U.S. tax return or an appropriate claim

33

Table of Contents

for refund to obtain a refund of the overpaid tax.

For a U.S. holder of our common stock, the IRS Forms 1099-DIV received from brokers may not be consistent with our determination of the amount that constitutes a “dividend” for U.S. federal income tax purposes or a stockholder may receive a corrected IRS Form 1099-DIV (and may therefore need to file an amended U.S. federal, state or local income tax return). We will attempt to timely notify our stockholders of available information to assist with income tax reporting (such as posting the correct information on our website). However, the information that we provide to our stockholders may be inconsistent with the amounts reported by a broker on IRS Form 1099-DIV, and the IRS may disagree with any such information and may make audit adjustments to a stockholder’s tax return.

For a non-U.S. holder of our common stock, “dividends” for U.S. federal income tax purposes will be subject to withholding of U.S. federal income tax at a 30% rate (or such lower rate as may be specified by an applicable income tax treaty) unless the dividends are effectively connected with the conduct of a U.S. trade or business. In the event that we are unable to timely determine the portion of our distributions that constitute a “dividend” for U.S. federal income tax purposes, or a stockholder’s broker or withholding agent chooses to withhold taxes from distributions in a manner inconsistent with our determination of the amount that constitutes a “dividend” for such purposes, a stockholder’s broker or other withholding agent may overwithhold taxes from distributions paid. In such a case, a stockholder generally would have to timely file a U.S. tax return or an appropriate claim for refund in order to obtain a refund of the overwithheld tax.

General Risks

We expect to use a significant portion of our cash flows to pay dividends to our stockholders and/or repurchase shares of our common stock, which could limit our ability to grow and make acquisitions.

We have previously announced that we plan to return capital to our stockholders through dividends to our stockholders and repurchasing shares of our common stock, which may cause our growth to proceed at a slower pace than that of businesses that reinvest their cash to expand ongoing operations. To the extent we issue additional shares of common stock in connection with any acquisitions or expansion capital expenditures, the payment of dividends on those additional shares may increase the risk that we will be unable to maintain or increase our per share dividend level. In addition, the incurrence of commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which, in turn, may reduce the cash that we have available to return capital to our stockholders through dividends and/or repurchases of shares of our common stock.

We may reduce or cease paying dividends on our common stock.

We are not obligated to pay dividends on shares of our common stock. Subject to preferences that may be applicable to any outstanding shares or series of preferred stock, holders of our common stock are only entitled to receive ratably such dividends (payable in cash, stock or otherwise), if any, as may be declared from time to time by our Board out of funds legally available for dividend payments. Our Board makes a determination each quarter as to the actual amount, if any, of dividends to pay on our common stock, based on various factors, some of which are beyond our control, including our operating cash flows, our working capital needs, our ability to access capital markets for debt and equity financing on reasonable terms, the restrictions contained in our debt instruments, our debt service requirements, credit metrics and the cost of acquisitions, if any. We may not have sufficient cash each quarter to pay dividends or maintain current or expected levels of dividends. Accordingly, we cannot guarantee that we will declare any future dividends at levels consistent with our historic practice or at all.

The price of our common stock may be volatile, and you could lose a significant portion of your investment.

The market price of our common stock could be volatile, and holders of common stock may not be able to resell their common stock at or above the price at which they acquired such securities due to fluctuations in the market price of our common stock.

Specific factors that may have a significant effect on the market price for our common stock include:

our operating and financial performance and prospects and the trading price of our common stock;
the level of our dividends;
quarterly variations in the rate of growth of our financial indicators, such as dividends per share of our common stock, net income and revenues;

34

Table of Contents

levels of indebtedness;
changes in revenue or earnings estimates or publication of research reports by analysts;
speculation by the press or investment community;
sales of our common stock by other stockholders;
announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures, securities offerings or capital commitments;
general market conditions;
changes in accounting standards, policies, guidance, interpretations or principles;
adverse changes in tax laws or regulations;
domestic and international economic, legal and regulatory factors related to our performance; and
Antero Resources’ operating and financial performance and prospects, and the trading price of its common stock.

There may be future dilution of our common stock, which could adversely affect the market price of shares of our common stock.

We are not restricted from issuing additional shares of our common stock out of our authorized capital. In the future, we may issue shares of our common stock to raise cash for future activities, acquisitions or other purposes. We may also acquire interests in other companies by using a combination of cash and shares of our common stock or only shares. We may also issue securities convertible into, or exchangeable for, or that represent the right to receive, shares of our common stock. Any of these events may dilute the ownership interests of our stockholders, reduce our earnings per share or have an adverse effect on the price of shares of our common stock.

Sales of a substantial amount of shares of our common stock in the public market could adversely affect the market price of our shares.

Sales of a substantial amount of shares of our common stock in the public market or grants to our directors and officers under the AM LTIP, or the perception that these sales or grants may occur, could reduce the market price of shares of our common stock. All of the shares of our common stock are freely tradable without restriction or further registration under the Securities Act, unless the shares are held by any of our “affiliates” as such term is defined in Rule 144 under the Securities Act. In addition, we are party to a registration rights agreement with Antero Resources, certain members of management and certain funds affiliated with Yorktown, pursuant to which we agreed to register the resale of shares of our common stock issued or paid to them in the Transactions. We cannot predict the size of future issuances of our common stock or securities convertible into our common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market price of our common stock.

Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (the “Court of Chancery”) will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, stockholders, employees or agents to us or our stockholders, (iii) any action or proceeding asserting a claim arising pursuant to any provision of the DGCL, our certificate of incorporation or our bylaws as to which the DGCL confers jurisdiction on the Court of Chancery or (iv) any action or proceeding asserting a claim against us governed by the internal affairs doctrine, in each such case subject to the Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. The foregoing provision does not apply to claims under the Securities Act, the Exchange Act or any claim for which the U.S. federal courts have exclusive jurisdiction. Furthermore, if the Court of Chancery lacks subject matter jurisdiction for any such matter, any state or federal court located within Delaware will be the sole and exclusive forum for that matter. Any person or entity purchasing or otherwise acquiring or holding any interest in shares

35

of our capital stock will be deemed to have notice of, and consented to, the provisions of certificate of incorporation described in the preceding sentence. This choice of forum provision may limit our stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with it or its directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition and results of operations.

We may issue preferred stock, which may have terms that could adversely affect the voting power or value of our common stock.

Our certificate of incorporation authorizes our Board to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our common stock respecting dividends and distributions, as our Board may determine. The terms of one or more classes or series of our preferred stock could adversely impact the voting power or value of our common stock. For example, we might grant holders of a class or series of our preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of our preferred stock could affect the residual value of our common stock.

Item 3. Legal Proceedings

Our operations are subject to a variety of risks and disputes normally incident to our business. As a result, we may, at any given time, be a defendant in various legal proceedings and litigation arising in the ordinary course of business.

We maintain insurance policies with insurers in amounts and with coverage and deductibles that we, with the advice of our insurance advisors and brokers, believe are reasonable and prudent. We cannot, however, assure you that this insurance will be adequate to protect us from all material expenses related to potential future claims for personal and property damage or that these levels of insurance will be available in the future at economical prices.

Veolia

The Company is currently involved in a consolidated lawsuit with Veolia Water Technologies, Inc. (“Veolia”) and Veolia Water North America Operating Services, LLC (“Veolia North America”) relating to the Clearwater Facility.

On March 13, 2020, Antero Treatment LLC (“Antero Treatment”), a wholly owned subsidiary of the Company, filed suit against Veolia and Veolia North America in the district court ofDenver County, Colorado, asserting claims of fraud, breach of contract and other related claims. Antero Treatment alleges that Veolia failed to meet its contractual obligations to design and build a “turnkey” wastewater disposal facility under a Design/Build Agreement dated August 18, 2015 (the “DBA”), and that Veolia fraudulently concealed certain design flaws during contract negotiations and continued to conceal and fraudulently misrepresent the impact of certain design changes post-execution of the DBA. Antero Treatment is seeking damages from Veolia of at least $457 million, which represents the Company’s recorded impairment of the idled Clearwater Facility. In the alternative, Antero Treatment sought rescission of the DBA and restitution of, at a minimum, the $230 million out-of-pocket costs paid to Veolia pursuant to the DBA. Antero Treatment also asserts related claims against Veolia North America, including equitable claims with respect to certain amounts Antero paid to Veolia North America.

On March 13, 2020, Veolia filed a separate suit against the Company, Antero Resources, and certain of the Company’s wholly owned subsidiaries (collectively, the “Antero Defendants”) in Denver County, Colorado. In its lawsuit, Veolia asserts breach of contract and equitable claims against the Antero Defendants for alleged failures under the DBA, including an allegation that the Antero Defendants improperly terminated the DBA to prevent Veolia from earning an approximate $26 million contract balance. The Antero Defendants vigorously deny Veolia’s claims. Veolia seeks money damages in an amount not yet specified. Veolia’s suit has been consolidated into the action filed by Antero Treatment.

On April 17, 2020, Veolia, Veolia North America and the Antero Defendants each filed partial motions to dismiss directed at certain claims asserted by the opposing party. On July 23, 2020, the Court dismissed Veolia’s equitable claims against the Antero

ItemITEM 6. Selected Financial Datafinancial data

The following table presents our selected historical financial data, for the periods and as of the dates indicated, for AMGPthe Company and our predecessor.its predecessors. Our predecessor, AMGP, was originally formed as ARMM to become the general partner of Antero Midstream Partners and converted into a limited partnership on May 4, 2017 in connection with our IPO. On March 12, 2019, pursuant to the Simplification Agreement, we completed the Transactions.

The Merger has been accounted for as an acquisition by AMGP of Antero Midstream Partners under ASC 805 – Business Combinations and accounted for as a business combination, with the assumed assets and liabilities of Antero Midstream Partners recorded at their estimated fair value. As a result of the Merger, our historical financial data for previous periods are not comparable to the years ended December 31, 2019 and 2020 or to our future financial results. The selected financial data for the years ended December 31, 2016, 2017 and 2018 are the financial statements of AMGP and its consolidated subsidiaries, which do not include Antero Midstream Partners and its subsidiaries.  Effective March 12, 2019, we began consolidating Antero Midstream Partners and its subsidiaries in our consolidated financial statements. As a result, our selected balance sheet financial data presented below at December 31, 2019 includes the financial position of Antero Midstream Partners and its subsidiaries, and our selected consolidated statements of operations and comprehensive income and cash flows data for the year ended December 31, 2019 include the results of operations of Antero Midstream Partners and its subsidiaries beginning on March 13, 2019. The historical selected consolidated statement of operations data included herein reflects that, prior to the Merger, AMGP’s only income resulted from distributions made on the incentive distribution rights (the “IDRs”) of Antero Midstream Partners and expenses were limited to general and administrative expenses and equity-based compensation. Please read “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations —Items Affecting Comparability of our Financial Results.”

Accordingly, we are also presenting our pro forma results of operations for the years ended December 31, 2018 and December 31, 2019, which give effect to the adjustments described in Exhibit 99.1 to this Annual Report on Form 10-K. The pro forma information presented below should be read in conjunction with the unaudited pro forma condensed combined financial statements, which are filed as Exhibit 99.1 to this Annual Report on Form 10-K and describe the assumptions and adjustments used in preparing such information. The pro forma adjustments are based on currently available information and certain estimates and

assumptions. Therefore, the actual adjustments may differ from the pro forma adjustments. However, management believes that the pro forma assumptions provide a reasonable basis for presenting the results of operations on a more meaningful basis.

The selected statement of operations data and statement of cash flows data for the years ended December 31, 2015, 2016,2018, 2019 and 20172020 and the balance sheet data as of December 31, 20162019 and 20172020 are derived from our audited consolidated financial statements included in Item 8 of this Annual Report on Form 10‑K.10-K.

Non-GAAP Financial Measures

We use Adjusted EBITDA as an important indicator of our performance. In our presentation of Adjusted EBITDA for the year ended December 31, 2020, net income (loss) and the corresponding adjustments reflect our actual results of operations.  In our presentation of Adjusted EBITDA for the years ended December 31, 2019 and 2018, net income (loss) and the corresponding adjustments reflect our pro forma results of operations. The pro forma information should be read in conjunction with the unaudited pro forma condensed combined financial statements, which are filed as Exhibit 99.1 to this Annual Report on Form 10-K. For more information, see “Items Affecting Comparability of Our Financial Results.”

We define Adjusted EBITDA as net income before net interest expense, income tax expense, depreciation, impairment, accretion and changes in fair value of contingent acquisition consideration, accretion of asset retirement obligations, equity-based compensation, excluding equity in earnings of unconsolidated affiliates, contract restructuring expenses, amortization of customer relationships, gains and losses on asset sales and including cash distributions from unconsolidated affiliates.

We use Adjusted EBITDA to assess:

the financial performance of our assets, without regard to financing methods capital structure or historical cost basis;

our operating performance and return on capital as compared to other publicly traded companies in the midstream energy sector, without regard to financing or capital structure; and

the viability of acquisitions and other capital expenditure projects.

Table of Contents

Adjusted EBITDA is a non-GAAP financial measure. The GAAP measure most directly comparable to Adjusted EBITDA is net income (loss). The non-GAAP financial measure of Adjusted EBITDA should not be considered as an alternative to the GAAP measure of net income (loss). Adjusted EBITDA presentations are not made in accordance with GAAP and have important limitations as an analytical tool because they include some, but not all, items that affect net income (loss). You should not consider Adjusted EBITDA in isolation or as a substitute for analyses of results as reported under GAAP. Our definition of Adjusted EBITDA may not be comparable to similarly titled measures of other corporations.

Our assets also include other flowback and produced water treatment facilities that we use to provide water treatment services to Antero Resources.

COVID-19 Pandemic

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. Governments have tried to slow the spread of the virus by imposing social distancing guidelines, travel restrictions and stay-at-home orders, which have caused a significant decrease in activity in the Appalachian Basin’s Marcellus Shaleglobal economy and Utica Shalethe demand for oil, and to a lesser extent, natural gas and NGLs. Also in March 2020, Saudi Arabia and Russia failed to agree to cut production of oil along with the Organization of the Petroleum Exporting Countries (“OPEC”), and Saudi Arabia significantly reduced the price at which it sells oil and announced plans to increase production, which contributed to a sharp drop in the price of oil. While OPEC, Russia and other allied producers reached an agreement in April 2020 to reduce production, oil prices have remained low. The imbalance between the supply of and demand for oil, as well as the uncertainty around the extent and timing of an economic recovery, have caused extreme market volatility and a substantial adverse effect on commodity prices.

As a midstream energy company, we are recognized as an essential business under various federal, state and local regulations related to the COVID-19 pandemic. We have continued to operate as permitted under these regulations while taking steps to protect the health and safety of our workers. We have implemented protocols to reduce the risk of an outbreak within our field operations, and these protocols have not reduced Antero Resources’ production and our throughput in a significant manner. A substantial portion of our non-field level employees continue to operate in remote work from home arrangements, and we have been able to maintain a consistent level of effectiveness through these arrangements, including maintaining our day-to-day operations, our financial reporting systems and our internal control over financial reporting.

Our midstream assets are located in West Virginia and Ohio. We believe thatOhio to serve the production of natural gas, NGLs and oil in the Appalachian Basin, primarily by Antero Midstream’s strategically located assetsResources. Our operations support well completion and integrated relationship withproduction operations for Antero Resources position itand as such, we are directly impacted by changes in Antero Resources’ operations. While Antero Resources has seen a decrease in the overall demand for its products, demand for natural gas and NGLs has not declined as much as demand for oil, and there has not been as substantial an oversupply of natural gas and NGLs as there has been of oil. Furthermore, the decrease in demand for oil has significantly reduced the number of rigs drilling for oil in the continental U.S. and, as a result, estimates of future gas supply associated with oil production have declined. Additionally, the restart of economic activity in Asia and Europe, coupled with lower refinery liquefied petroleum gas (“LPG”) production from refineries in the U.S., Europe and Asia during the second quarter, provided support for international LPG prices relative to beoil. Further, reductions in OPEC+ and North American oil production and the associated NGL volumes are expected to have a leading Appalachian midstream provider across the full midstream value chain.

Our revenues are generated solely from the cash distributions we receive from Antero Midstream through our interests in IDR LLC. Because our success is dependent upon the operationssupportive effect on propane and management of Antero Midstream and its resulting performance, Antero Midstream’s Annual Report on Form 10‑K forbutane prices into 2021. During the year ended December 31, 2017,2020, all of our gathering, compression and processing revenues were derived from the production of natural gas.

Neither our nor Antero Resources’ supply chain has been includedexperienced any significant interruptions. The industry continues to experience storage capacity constraints for oil and certain NGL products, and Antero Resources may become subject to those constraints if it is not able to sell its production or certain components thereof, or enter into additional storage arrangements. The lack of a market or available storage for any one NGL product or oil could result in this filingAntero Resources having to delay or discontinue well completions and commercial production or shut in production for other products as Exhibit 99.1it has disclosed that it cannot curtail the production of individual products in a meaningful way without reducing the production of other products. Antero Resources has indicated that

Table of Contents

the potential impacts of these constraints may include partial shut-in of production, although it is not able to determine the extent of or for how long any shut-ins may occur. Antero Resources has also indicated that because some of its wells produce rich gas, which is processed, and incorporated hereinsome produce dry gas, which does not require processing, it has the ability to change the mix of products that it produces and wells that it completes to adjust its production to address takeaway capacity constraints for certain products. For example, Antero Resources has indicated that it has the ability to shut-in rich gas wells and still produce from its dry gas wells if processing or storage capacity of NGL products becomes further limited or constrained. Also, prior to the COVID-19 pandemic, Antero Resources had developed a diverse set of buyers and destinations, as well as in-field and off-site storage capacity for its condensate volumes. Since the outbreak of the pandemic, Antero Resources has expanded its customer base and its condensate storage capacity within the basin. However, any production curtailments or shut-ins by reference.Antero Resources or our other customers will reduce throughput for our gathering and processing systems. In addition, if our customers delay or discontinue drilling or completion activities, it will reduce the volumes of water that we handle and therefore revenues for our water distribution and handling business.

Our SourcesIn addition, Antero Resources announced in April 2020 that it had reduced its drilling and completion capital budget for 2020 by approximately 34%. Antero Resources continues to monitor its five-year drilling plan and has indicated it will make further revisions as appropriate. Reducing its 2020 capital budget may impact production levels in 2021 and forward to the extent fewer wells are brought online, which will directly impact our throughput and cash flows for the same time periods.

During the years ended December 31, 2019 and 2020, we recognized various impairment charges related to certain freshwater delivery system assets and fully impaired our Clearwater Facility and goodwill. Additional impairment charges related to our assets may occur if we experience disruptions in operations, decreases in our revenues or other adverse effects of Revenuethe COVID-19 pandemic.

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted. The CARES Act allows corporations with net operating losses (“NOLs”) incurred in 2018, 2019 and 2020 to carry back such NOLs to each of the five years preceding the year of the NOLs, beginning with the earliest year in which there was taxable income, and claim an income tax refund in the applicable carryback years. As a result of this NOLs carryback provision in the CARES Act, we were able to recognize an income tax refund receivable in March 2020 of $55 million, including $11 million in income tax benefit for the current year and $44 million of previously recognized deferred income tax benefit. As of December 31, 2020, we had received $39 million of this refund.

The COVID-19 pandemic, commodity market volatility and resulting financial market instability are variables beyond our ownership interestcontrol and may adversely impact our generation of funds from operating cash flows, distributions from unconsolidated affiliates, available borrowings under our Credit Facility and our ability to access the capital markets.

Commodity Price Risk

Our gathering and compression and water services agreements with Antero Resources provide for fixed-fee structures, and we intend to continue to pursue additional fixed-fee opportunities with Antero Resources and third parties in IDR LLC, we are positionedorder to grow our distributions disproportionately relativeavoid direct commodity price exposure. However, to the growth rateextent that our future contractual arrangements with Antero Resources or third parties do not provide for fixed-fee structures, we may become subject to commodity price risk. We are subject to commodity price risks to the extent that they impact Antero Resources’ development program and production and therefore our gathering, compression and water handling volumes. We cannot predict to what extent our business would be impacted by lower commodity prices and any resulting impact on Antero Resources’ operations.

2021 Capital Investment

During 2021, we plan to expand our existing Appalachian Basin gathering, compression and water handling infrastructure to accommodate Antero Resources’ announced development plans. Antero Resources’ announced 2021 consolidated drilling and completion budget of $590 million. Antero Resources announced that it plans to operate three drilling rigs and complete between 65 and 70 horizontal wells, substantially all of which are located on acreage dedicated to us. A further or extended decline in commodity prices could cause some of the development and production projects of Antero Midstream’s common unit distributions. Accordingly,Resources or third parties to be uneconomic or less profitable, which could reduce gathering and water handling volumes in our primary business objective is to increasecurrent and future potential areas of operation. Those reductions in gathering and water handling volumes could reduce our cash available for distribution to our shareholders through the execution by Antero Midstream of its business strategy. Unless we directly acquirerevenue and hold assets or businesses in the future, our revenues will be generated solely from the cash distributions we receive from Antero Midstream through our interests in IDR LLC.

Financial Presentation

We own the general partner interest in Antero Midstream through our interest in AMP GP and own all of the capital interests in IDR LLC, which we control as managing member. We have no separate operating activities apart from those conducted by Antero Midstream, and our cash flows consist solelyand adversely affect our ability to return capital to holders of distributions we receive relating to Antero Midstream’s distributions on its IDRs. Our financial statements are based on the equity method of accounting for our investment in Antero Midstream.

Sources of Our Revenues

Our gathering and compression revenues are driven by the volumes of natural gas we gather and compress, and our water handling revenues are driven by quantities of fresh water delivered to our customers to support their well completion operations and produced water treated. Pursuant to our long-term contracts with Antero Resources, we have secured long-term dedications covering a significant portion of Antero Resources’ current and future acreage for gathering and compression services. We have also entered into a long-term water services agreement covering Antero Resources’ 515,000 net acres in West Virginia and Ohio, with a right of first offer on all future areas of operation. Under the agreement, we receive a fixed fee for all fresh water deliveries by pipeline directly to the well site, subject to annual CPI adjustments. In addition, we also provide fluid handling services for flowback and produced water, including blending, storage and transportation operations. These operations, along with our fresh water delivery systems, support well completion and production operations for Antero Resources. These services are provided by us directly or through third-parties with which we contract. For flowback and produced water services provided by third-parties, Antero Resources reimburses our third-party out-of-pocket costs plus 3%. For flowback and produced water services provided by us, we charge Antero Resources a cost of service fee. The initial term of the water services agreement runs to 2035. All of Antero Resources’ existing acreage is dedicated to us for gathering and compression services except for existing third-party commitments. Approximately 135,000 gross leasehold acres characterized by dry gas and liquids-rich production have been previously dedicated to third-party gatherers.

Our gathering and compression operations are substantially dependent upon natural gas and oil production from Antero Resources’ upstream activity in its areas of operation. In addition, there is a natural decline in production from existing wells that are connected to our gathering systems. Although we expect that Antero Resources will continue to devote substantial resources to the development of oil and gas reserves, we have no control over this activity and Antero Resources has the ability to reduce or curtail such development at its discretion.

Our water handling operations are substantially dependent upon the number of wells drilled and completed by Antero Resources, as well as Antero Resources’ production. As of December 31, 2020, Antero Resources had disclosed estimated net proved reserves 17.6 Tcfe, of which 57% was natural gas, 42% were NGLs and 1% was oil. As of December 31, 2020, Antero Resources’ drilling inventory consisted of 2,133 identified potential horizontal well locations, approximately 1,531 of which were located on acreage dedicated to us, providing us with significant opportunity for growth as Antero Resources’ drilling program continues and its production increases.

How We Evaluate Our Operations

We use a variety of financial and operational metrics to evaluate our performance. These metrics help us identify factors and trends that impact our operating results, profitability and financial condition. The key metrics we use to evaluate our business are provided below.

Adjusted EBITDA

We use Adjusted EBITDA as a performance measure to assess the ability of our assets to generate cash sufficient to pay interest costs, support indebtedness and return capital to stockholders. Adjusted EBITDA is a non-GAAP financial measure. See “Item 6. Selected Financial Data—Non-GAAP Financial Measures” below for more information regarding this financial measure, including a reconciliation to its most directly comparable GAAP measure.

Table of Contents

Gathering and Compression Throughput

We must continually obtain additional supplies of natural gas and oil to maintain or increase throughput on our systems. Our ability to maintain existing supplies of natural gas and oil and obtain additional supplies is primarily impacted by our acreage dedication and the level of successful drilling activity by Antero Resources and the potential for acreage dedications with and successful drilling by third-party producers. Any increase in our throughput volumes over the near term will likely be driven by Antero Resources continuing its drilling and development activities on its Appalachian Basin acreage.

Water Handling Volumes

Our fresh water volumes are primarily driven by hydraulic fracturing activities conducted as part of well completions. Our treatment volumes are primarily driven by produced water volumes, which are a function of Antero Resources’ production. Other fluid handling volumes are driven by hydraulic fracturing activities and produced water volumes. Antero Resources’ consolidated acreage positions allow us to provide fresh water and other fluid handling services for Antero Resources’ completion activities in a more efficient manner. However, to the extent that Antero Resources’ drilling and completion schedule is not met, or Antero Resources uses less fresh water and other fluid handling services in its well completion operations than expected (for example, due to a reduction in completions), and production declines, our water volumes may decline.

Principal Components of Our Cost Structure

The following items are the primary components of our operating expenses.

Direct Operating. We seek to maximize the profitability of our operations in part by minimizing, to the extent appropriate, expenses directly tied to operating and maintaining our assets. We schedule and conduct maintenance over time to avoid significant variability in our direct operating expense and minimize the impact on our cash flow. Gathering and compression operating costs consist primarily of labor, water disposal, pigging, fuel, monitoring, repair and maintenance, utilities and contract services. Gathering and compression operating costs vary with the miles of pipeline and number of compressor stations in our gathering and compression system. Fresh water operating expenses consist primarily of labor, pigging, monitoring, repair and maintenance and contract services. Fresh water operating costs vary with the miles of pipeline, number of pumping stations and to a lesser extent the number of well completions in the Appalachian Basin for which we deliver fresh water and number of impoundments in our fresh water system. Other water handling costs, which include the costs related to water blending, relate to contract services performed by us and third parties. Our other water handling costs consist of labor, monitoring and repair and maintenance costs. Wastewater treatment costs vary directly with the water volumes treated, and the operating efficiency of the Clearwater Facility which was idled in September 2019 for the foreseeable future. The other primary drivers of our direct operating expense include maintenance and contract services, regulatory and compliance expense and ad valorem taxes.
General and Administrative. Our general and administrative expenses include direct charges and costs charged by Antero Resources. These costs relate to: (i) various business services, including payroll processing, accounts payable processing and facilities management, (ii) various corporate services, including legal, accounting, treasury, information technology and human resources and (iii) compensation, including certain equity-based compensation. These expenses are charged to the Company based on the nature of the expenses and are apportioned based on a combination of the Company’s proportionate share of gross property and equipment, capital expenditures and labor costs, as applicable. Management believes these allocation methodologies are reasonable.

Our general and administrative expenses also include equity-based compensation costs related to the Antero Midstream GP LP Long-Term Incentive Plan (“AMGP LTIP”) and the Series B Units prior to the Transactions. Equity-based compensation after the Transactions include (i) costs allocated to Antero Midstream Partners by Antero Resources for grants made prior to the Transactions pursuant to Antero Resources’ long-term incentive plan, (ii) costs due to Antero Midstream Corporation LTIP (the “AM LTIP”) and (iii) Series B Exchange. As of December 31, 2020, there were no unvested awards related to the AMGP LTIP or Series B Exchange.

Impairment. We evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the related carrying values of the assets may not be recoverable. If the carrying values of the assets are deemed not recoverable, the carrying values are reduced to their estimated fair value. In 2019, our impairment expense primarily related to (i) the Clearwater Facility, which was idled in the third quarter of 2019 and (ii) the impairment of goodwill associated with the fresh water delivery and services reporting unit. In 2020, our impairment expense primarily related to (i) the impairment of

46

Table of Contents

goodwill associated with our gathering and processing reporting unit and (ii) the fresh water delivery assets in the Utica Shale region.
Depreciation. Depreciation consists of our estimate of the decrease in value of the assets capitalized in property and equipment as a result of using the assets throughout the applicable year. Depreciation is computed over the asset’s estimated useful life using the straight-line basis. See Note 8—Property and Equipment to our consolidated financial statements for additional information on our asset classes and estimated lives of our assets.
Interest. From January 1, 2019 through March 12, 2019, interest expense related to interest incurred on borrowings under AMGP’s credit facility, which was terminated on March 12, 2019 in connection with the Transactions. Following the closing of the Transactions on March 12, 2019, interest expense represented interest related to: (i) borrowings under our revolving credit facility, (ii) borrowings of $650 million under our 5.375% senior notes due September 15, 2024 (the “2024 Notes”), (iii) borrowings of $550 million of our 7.875% senior notes due May 15, 2026 (the “2026 Notes”), (iv) borrowings of $650 million of our 5.75% senior notes due March 1, 2027 (the “2027 Notes”), (v) borrowings of $650 million of our 5.75% senior notes due January 15, 2028 (the “2028 Notes”), (vi) operating leases and (vii) amortization of deferred financing costs incurred in connection with the revolving credit facility and the issuance of the 2024 Notes, 2026 Notes, 2027 Notes and 2028 Notes.
Income tax expense.We are subject to state and federal income taxes but are currently not in a cash tax paying position with respect to state and federal income taxes. The difference between our financial statement income tax expense and our federal income tax liability is primarily due to the differences in the tax and financial statement treatment of our investment in Antero Midstream Partners. We have recorded deferred income tax benefit to the extent our deferred tax assets exceed our deferred tax liabilities. Our deferred tax assets result from temporary differences between tax and financial statement income primarily from goodwill impairment and net operating loss carryforwards. At December 31, 2020, we had approximately $211 million of U.S. federal net operating loss carryforwards (“NOLs”), and approximately $315 million of state NOLs. The amount of deferred tax assets considered realizable, however, could change in the near term as we generate taxable income or as estimates of future taxable income are reduced. See Note 9—Income Taxes to our consolidated financial statements for a discussion of our deferred tax position and income tax expense.

Items Affecting Comparability of Our Financial Results

Certain of theOur historical financial results discussed below mayare not be comparable to our future financial results primarily as a result of the significant increaseMerger. The Merger has been accounted for as an acquisition by AMGP of Antero Midstream Partners under ASC 805, Business Combinations, and accounted for as a business combination with the acquired assets and liabilities of Antero Midstream Partners recorded at estimated fair value. Effective March 12, 2019, Antero Midstream commenced consolidating Antero Midstream Partners and its subsidiaries in the scopeconsolidated financial statements of Antero Midstream’s operations over the last several years. Antero Midstream’s gathering and compression and water handling and treatment systems are relatively new, as a substantial portion of these assets have been built within the last four years. Accordingly, Antero Midstream’s revenues and expenses over that time reflect the significant increase in its operations. Similarly, Antero Resources has experienced significant changes in its production and drilling and completion schedule over that same period.Midstream. As our income is predicated on Antero Midstream’s cash available for distribution, any change in Antero Midstream’s revenue and expenses could have a direct impact on us. Accordingly, it may be difficult to project trends from our historical financial data going forward.

Certain of the historical financial results discussed below may not be comparable to future financial results primarily as a result, our consolidated balance sheet as of December 31, 2019 includes the significant increase infinancial position of Antero Midstream’sMidstream Partners and its subsidiaries, and our consolidated statements of operations and comprehensive income and cash distributions. As our sole source of revenue, any change in Antero Midstream’s cash distributions will have a direct financial impact on us. Distributions toflows for the IDRs began inyear ended December 31, 2019 include the fourth quarter of 2015 and have increased significantly since that time as the IDRs have been entitled to a greater marginal percentage interest in distributions.

In addition, our historical results of operations do notof Antero Midstream Partners and its subsidiaries beginning on March 13, 2019.

The historical consolidated financial statements included herein are the financial statements of Antero Midstream, formerly AMGP, which prior to the Merger reflect that AMGP’s only income resulted from distributions made on the incrementalIDRs of Antero Midstream Partners and expenses we are now incurring aswere limited to general and administrative expenses and equity-based compensation. The consolidated financial statements for the year ended December 31, 2019 include the results of Antero Midstream Partners and its subsidiaries beginning on March 13, 2019.

Accordingly, in addition to presenting a resultdiscussion of being a publicly traded company. Our historicalour results of operations as reported, we are also reflect a U.S. federal corporate tax rate of 35%.  Effective January 1, 2018, the U.S. federal corporate tax rate was reduced from 35% to 21%. Accordingly,presenting our historicalpro forma results of operations, will reflectwhich give effect to the adjustments described in Exhibit 99.1 to this Annual Report on Form 10-K. The pro forma information presented below should be read in conjunction with the unaudited pro forma combined financial statements, which are filed as Exhibit 99.1 to this Annual Report on Form 10-K and describe the assumptions and adjustments used in preparing such information. The pro forma adjustments are based on currently available information and certain estimates and assumptions. Therefore, the actual adjustments may differ from the pro forma adjustments. However, management believes that the pro forma assumptions provide a higher U.S. federal corporate tax rate in comparison to our future financial results.

Equity in earningsRevenue and Direct Operating Expenses. Revenues from Antero Resources and direct operating expenses for the year ended December 31, 2019 reflect 294 days of revenue and operating expenses generated by Antero Midstream Partners LP. Equity in earningsafter the completion of Antero Midstream increasedthe Transactions on March 12, 2019.

General and administrative expenses. General and administrative expenses (excluding equity-based compensation expense) decreased 12% from $16.9$45 million for the year ended December 31, 20162019 to $69.7$39 million for the year ended December 31, 2017. Antero Midstream’s per-unit distribution increased in the year ended December 31, 2017 from the year ended December 31, 2016, resulting in an increase in distributions on the IDRs. In addition, IDR LLC receives a portion2020. The decrease was primarily due to cost reduction efforts, partially offset by inclusion of general and administrative expenses of Antero Midstream distributions based on a tiered approach, in whichPartners after the percentage receivedcompletion of the total distribution increases at certain levels. The highest tier, in which cash distributions to Antero Midstream’s unitholders exceeds $0.255 per common unit it any quarter, entitles IDR LLC to 50% of said distribution. This tier was met in each quarter of 2017, opposed to only the third and fourth quarter of 2016, which contributed to the increase in our equity in earnings of Antero Midstream.

General and administrative expenses. General and administrative expenses increasedTransactions on March 12, 2019. Equity-based compensation decreased from $0.8$74 million for the year ended December 31, 20162019 to $6.2$13 million for the year ended December 31, 2017.

See Note 4 to the consolidated financial statements.

Income tax expense. Income taxgoodwill expense increased from $6.4associated with our fresh water delivery and services reporting unit. Impairment of goodwill expense of $575 million for the year ended December 31, 20162020 was associated with our gathering system due to $26.3declines in commodity prices and the general industry environment.

Impairment of property and equipment expense. Impairment of property and equipment expense of $410 million for the year ended December 31, 2017. The increase is2019 was primarily due to higher taxable income as a resultthe idling of the increase in equity in earningsClearwater Facility. Impairment of Antero Midstream  related to the IDRs, netproperty and equipment expense of the increase in general and administrative expenses.

The difference between income tax expense and expected income tax expense for financial statement purposes computed by applying the federal statutory rate of 35% to pre-tax income is caused by nondeductible equity-based compensation and IPO expenses, and the effect of state income taxes.

As a result of the Tax Cuts and Job Act enacted on December 22, 2017, the U.S. corporate income tax rate will be reduced to 21% for tax years beginning in 2018.

General and administrative expenses. General and administrative expenses increased from $0 for the year ended December 31, 2015 to $0.8$8 million for the year ended December 31, 2016. In2019 relates to the year ended December 31, 2015, we did not incur any significant general and administrative costs; however,contingent consideration payment that was made in the fourth quarter of 2016 we incurred general and administrative costs primarily in connection with our IPO.January 2020. No additional contingent consideration is expected to be paid.

Income taxInterest expense.Income tax Interest expense increased $37 million from $0.5$110 million for the year ended December 31, 20152019 to $6.4$147 million for the year ended December 31, 2016. The increase is primarily due to higher taxable income2020 as a result of the increase in equity in earningsacquisition of Antero Midstream related toPartners (which included the IDRs.assumption of approximately $2.4 billion of debt) and Antero Midstream Partners’ issuance of the 2028 Notes in June 2019 and 2026 Notes in November 2020.

The difference between income tax expense and expected income tax expense computed by applying the federal statutory rateOperating loss. Total operating loss decreased from a loss of 35% to pre-tax income is caused by nondeductible IPO expenses and the effect of state income taxes.

Net income and comprehensive income. Net income and comprehensive income increased from net income of $0.8$398 million for the year ended December 31, 20152019 to net income of $9.7$118 million for the year ended December 31, 2016.2020. The decrease was due to (i) higher revenue and lower direct operating expenses and general and administrative expenses between periods as a result of the acquisition of Antero Midstream Partners on March 12, 2019 and cost reduction efforts and (ii) lower impairment of property and equipment and impairment of customer relationships for the year ended December 31, 2020 as compared to the same period in 2019, partially offset by higher impairment of goodwill expense for the year ended December 31, 2020 as compared to the same period in 2019.

Equity in earnings in unconsolidated affiliates increased by $35 million from $51 million for the year ended December 31, 2019 to $86 million for the year ended December 31, 2020 primarily attributable to an increase in the level of operations at the Joint Venture during the year ended December 31, 2020.

Income tax benefit (expense). Income tax benefit for the year ended December 31, 2019 was $102 million. Income tax benefit for the year ended December 31, 2020 was $56 million primarily due to the loss before taxes for the year ended December 31, 2020 coupled with an $11 million rate benefit related to the carryback of NOLs to prior tax years.  This carryback generated a federal income tax receivable of $55 million, of which $39 million had been received as of December 31, 2020. This carryback is a result of a provision included in the CARES Act that allows corporations with NOLs incurred in 2018, 2019 and 2020 to carry back such NOLs to each of the five years preceding the year of the NOLs, beginning with the earliest year in which there is taxable income, and claim an income tax refund in the applicable carryback years.  The income tax receivable account is classified as a current asset on the balance sheet.

Pro Forma Segment Results of Operations

Unless the context otherwise requires, references in this “Pro Forma Segment Results of Operations” to the “Company,” “we,” “us” or “our” refer to, and the results of operations discussed below relate to, the combined results of Antero Midstream Corporation and Antero Midstream Partners as if the Transactions had occurred on January 1, 2019.

The pro forma segment results of operations and the pro forma operations data for the year ended December 31, 2019 have been prepared to give pro forma effect to the Transactions as if they had occurred on January 1, 2019. The pro forma adjustments are based on currently available information and certain estimates and assumptions, including the final purchase price allocation for the acquisition of Antero Midstream Partners. Therefore, the actual adjustments may differ from the pro forma adjustments. However, management believes that the pro forma assumptions provide a reasonable basis for presenting the significant effects of the Transactions.

The pro forma information is for illustrative purposes only. If the Transactions had occurred on January 1, 2019, operating results might have been materially different from those presented in the pro forma financial information. The pro forma financial information should not be relied upon as an indication of operating results that we would have achieved if the Transactions had taken place on January 1, 2019. In addition, future results may vary significantly from the pro forma results reflected herein and should not be relied upon as an indication of our future results. The pro forma information presented below should be read in conjunction with the unaudited pro forma combined financial statements, which are filed as Exhibit 99.1 to this Annual Report on Form 10-K.

Discussion of Results of Operations for the Year Ended December 31, 2019 (Pro Forma) Compared to Year Ended December 31, 2020

Revenues. Revenues decreased by 10% from $997 million, including the amortization of customer relationships of $71 million, for the year ended December 31, 2019 to $901 million, including the amortization of customer relationships of $71 million, for the year ended December 31, 2020. Gathering and processing revenues increased by 6%, from $638 million for the year ended December 31, 2019 to $674 million for the year ended December 31, 2020. Water handling revenues decreased by 39%, from $372 million for the year ended December 31, 2019 to $226 million for the year ended December 31, 2020. These fluctuations primarily resulted from the following:

Gathering and Processing

low pressure gathering revenue decreased $8 million year over year due to $48 million in rebates to Antero Resources for achieving certain volumetric targets, partially offset by an increase in throughput volumes of 282 MMcf/d, which was due to 108 additional wells connected to our system during the year ended December 31, 2020;
high pressure gathering revenue increased $25 million year over year due to an increase in throughput volumes of 292 MMcf/d, primarily as a result of the addition of one new high pressure gathering line placed in service and additional wells connected to our system during the year ended December 31, 2020; and
compression revenue increased $26 million year over year due to an increase in throughput volumes of 335 MMcf/d, primarily due to the addition of one new compressor station that was placed in service and additional wells connected to our system during the year ended December 31, 2020.

52

Table of Contents

Water Handling

fresh water delivery revenue decreased $42 million year over year due to a decrease in fresh water delivery of 32 MBbl/d, as a result of a decrease in the number of wells completed by Antero Resources due to its reduced drilling and completion program during the year ended December 31, 2020;
revenue from the Clearwater Facility decreased $32 million year-over-year from $32 million for the year ended December 31, 2019 to zero during the year ended December 31, 2020 due to the idling of the Clearwater Facility in September 2019; and
other fluid handling services revenue decreased $66 million primarily due to a $76 million decrease in services that are billed at cost plus 3% as a result of operational efficiencies associated with our flowback and produced wastewater services, which commenced in the fourth quarter of 2019, and cost reductions, partially offset by a $10 million increase in water blending services.

Direct operating expenses. Total direct operating expenses decreased from $261 million for the year ended December 31, 2019 to $165 million for the year ended December 31, 2020. Gathering and processing direct operating expenses increased by 7% from $53 million for the year ended December 31, 2019 to $57 million for the year ended December 31, 2020. The increase was primarily due to the cost associated with the new compressor station that came online in 2020 as well as higher throughput volumes between periods. Water handling direct operating expenses decreased 48% from $208 million for the year ended December 31, 2019 to $109 million for the year ended December 31, 2020. The decrease was primarily due to operational efficiencies associated with flowback and produced wastewater services.

General and administrative (excluding equity-based compensation) expenses. General and administrative expenses (excluding equity-based compensation expense) decreased by 13% from $46 million for the year ended December 31, 2019 to $39 million for the year ended December 31, 2020 primarily due to cost reduction efforts, partially offset by legal costs associated with the Clearwater Facility

Equity-based compensation expenses. Equity-based compensation expenses decreased from $76 million for the year ended December 31, 2019 to $13 million for the year ended December 31, 2020 due to the Exchanged B Units that were fully vested on December 31, 2019.

Impairment of goodwill expense. Impairment of goodwill expense of $340 million for the year ended December 31, 2019 reflects an impairment of the goodwill that was associated with the Clearwater Facility and the fresh water delivery and services reporting unit. Impairment of goodwill expense of $575 million for the year ended December 31, 2020 reflects an impairment of the goodwill that was associated with our gathering system due to declines in commodity prices and the general industry environment.

Impairment of property and equipment expense. Impairment of property and equipment expense of $417 million for the year ended December 31, 2019 was primarily for the idling of the Clearwater Facility and the decommissioning of assets related to a third-party compressor station. Impairment of property and equipment expense of $98 million for the year ended December 31, 2020 was primarily for the impairment of fresh water delivery assets in the Utica Shale region.

Impairment of customer relationships expense. Impairment of customer relationships expense of $12 million for the year ended December 31, 2019 reflects an impairment of the customer relationships that were associated with the Clearwater Facility.

Depreciation expense. Total depreciation expense decreased by 10%, from $120 million for the year ended December 31, 2019 to $109 million for the year ended December 31, 2020. The decrease was primarily due to assets that were impaired during the third quarter of 2019 and the first quarter of 2020, partially offset by additional gathering, compression and water handling assets placed in service in 2020.

Accretion and change in fair value of contingent acquisition consideration. Accretion expense of $10 million for the year ended December 31, 2019 relates to the contingent consideration payment that was made in January 2020. No additional contingent consideration is expected to be paid.

Interest expense. Interest expense increased by 13%, from $131 million for the year ended December 31, 2019 to $147 million for the year ended December 31, 2020 primarily due to an increase in interest expense incurred on (i) higher borrowings under the Credit Facility during 2020, (ii) the 2027 Notes that were issued during the first quarter of 2019, (iii) the 2028 Notes that were issued during the second quarter of 2019 and (iv) the 2026 Notes that were issued during the fourth quarter of 2020.

The increase in cash flows from operating activities in 2017 from 2016 of $18.6 million was due to an increase in distributions from Antero Midstream of $43.1 million in 2017 compared to 2016, partially offset by a $5.5 million increase in general and administrative expenses (primarily attributable to the IPO) and a $19.1 million payment in 2017 for 2016 and 2017 income taxes. These changes, together with other working capital items, resulted in the net increase in cash provided by operating activities. The increase inactivities for the year ended December 31, 2020 compared to the year ended December 31, 2019 was primarily the result of higher gathering and processing revenues, lower

Additionally, cash flows provided by investing activities for the year ended December 31, 2019 included $620 million of cash received upon the acquisition of Antero Midstream Partners LP, which amount was borrowed by Antero Midstream Partners under the Credit Facility to fund, in part, $599 million of cash paid to Antero Midstream Partners unitholders as consideration in the Merger.

2020 Capital Investments and 2021 Capital Budget

Antero Midstream Partners’ capital spending for the year ended December 31, 2020 included investing activities of (i) $141 million to our gathering system, (ii) $41 million to our water handling system and (iii) $25 million invested in our Joint Venture.

The Board approved a 2021 capital budget with a range of $240 million to $260 million, which includes approximately $65 million of additional growth capital supporting the increased volumes expected from Antero Resources’ drilling partnership in addition to its previously disclosed maintenance capital program for 2021. Our capital budgets may be adjusted as business conditions warrant. If natural gas, NGLs and oil prices decline to levels below acceptable levels or costs increase to levels above acceptable levels, Antero Resources could choose to defer a significant portion of its budgeted capital expenditures until later periods. As a result, we may also defer a significant portion of our budgeted capital expenditures to achieve the desired balance between sources and uses of liquidity and prioritize capital projects that we believe have the highest expected returns and potential to generate near-term cash flows. We routinely monitor and adjust our capital expenditures in response to changes in Antero Resources’ development plans, changes in prices, availability of financing, acquisition costs, industry conditions, the timing of regulatory approvals, success or lack of success in Antero Resources’ drilling activities, contractual obligations, internally generated cash flows and other factors both within and outside our control.

Debt Agreements

Credit Facility

Antero Midstream Partners, as borrower (the “Borrower”), entered into a senior secured revolving credit facility (the “Credit Facility”) with a consortium of banks on October 26, 2017. The Credit Facility includes fall away covenants and lower interest rates that are triggered if and when the Borrower elects to enter into an Investment Grade Period (as defined in the Credit Facility). The Credit Facility provides for borrowing under either the Eurodollar Rate or the Base Rate (as each term is defined in the Credit Facility).

The Credit Facility has lender commitments of $2.13 billion and matures on October 26, 2022. As of December 31, 2020, we had $614 million of borrowings and no letters of credit outstanding under the Credit Facility.

55

Table of Contents

We have a choice of borrowing in Eurodollars or at the base rate. Principal amounts borrowed are payable on the maturity date with such borrowings bearing interest that is payable (i) with respect to base rate loans, quarterly and (ii) with respect to Eurodollar loans, the last day of each Interest Period (as defined below); provided that if any Interest Period for a Eurodollar loan exceeds three months, interest will be payable on the respective dates that fall every three months after the beginning of such Interest Period. Eurodollar loans bear interest at a rate per annum equal to the LIBOR Rate administered by the ICE Benchmark Administration for one, two, three, six or, if available to the lenders, twelve months (the “Interest Period”) plus an applicable margin ranging from 125 to 225 basis points (subject to certain exceptions), depending on the leverage ratio then in effect. Base rate loans bear interest at a rate per annum equal to the greatest of (i) the agent bank’s reference rate, (ii) the federal funds effective rate plus 50 basis points and (iii) the rate for one month Eurodollar loans plus 100 basis points, plus an applicable margin ranging from 25 to 125 basis points (subject to certain exceptions) depending on the leverage ratio then in effect.

The Credit Facility is guaranteed by our subsidiaries and is secured by mortgages on substantially all of Antero Midstream Partners’ and its subsidiaries’ properties. The Credit Facility contains restrictive covenants that may limit our ability to, among other things:

incur additional indebtedness;
sell assets;
make loans to others;
make investments;
enter into mergers;
make certain restricted payments;
incur liens; and
engage in certain other transactions without the prior consent of the lenders.

The Credit Facility also requires us to maintain the following financial ratios (subject to certain exceptions):

a consolidated interest coverage ratio, which is the ratio of our consolidated EBITDA to its consolidated current interest charges of at least 2.5 to 1.0 at the end of each fiscal quarter;
a consolidated total leverage ratio, which is the ratio of consolidated debt to consolidated EBITDA, of not more than 5.00 to 1.00 at the end of each fiscal quarter; provided that, at our election (the “Financial Covenant Election”), the consolidated total leverage ratio shall be no more than 5.25 to 1.0; and
after a Financial Covenant Election, a consolidated senior secured leverage ratio covenant rather than the consolidated total leverage ratio covenant, which is the ratio of consolidated senior secured debt to consolidated EBITDA, of not more than 3.75 to 1.0.

We were in compliance with the applicable covenants and ratios as of December 31, 2020.

Critical Accounting Policies and Estimates

The following discussion relates to the critical accounting policies and estimates for both the Company and our Predecessor. The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our consolidated financial statements.

Equity-Based Compensation

Equity-based compensation awards are measured at their grant date fair valueour more significant accounting policies, estimates and related compensation cost is recognized over the vesting period of the grant. Compensation cost for awards with only service conditions is recognized on a straight-line basis over the requisite service period of the entire reward. Estimating the fair value of each award involves a number ofjudgments below. We believe these accounting policies reflect our more significant estimates including interest rates, expected volatility of our equity value, and expected distributions on the Series B Units.

Equity Method Accounting

We use the equity method to account for our investment in Antero Midstream because we have the ability to exercise significant influence over, but not control, Antero Midstream. Accordingly, we record, in the period in which it is earned, distributions from Antero Midstream associated with our ownership of IDR LLC, which owns 100% of Antero Midstream’s IDRs. The financial statements of AMGP do not consolidate the accounts of Antero Midstream. The accounts of Antero Midstream, a variable interest entity, are included in the consolidated financial statements of Antero Resources, the primary beneficiary of Antero Midstream.

New Accounting Pronouncements

On August 26, 2016, the FASB issued ASU 2016‑15, Classification of Certain Cash Receipts and Cash Payments, which removes diversity in practice in how certain cash receipts and payments are presented and classified in the statement of cash flows, including the presentation of distributions received from equity method investees. The new standard becomes effective for AMGP on January 1, 2018. We do not believe that this standard will have a material impact on our ongoing financial reporting upon adoption.

On June 16, 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which requires an entity to measure its financial assets at the net amount expected to be collected.  The ASU will replace most existing guidance in GAAP regarding the valuation of financial assets when it becomes effective.  The new standard becomes effective for us on January 1, 2020.  We do not believe that this standard will have a material impact on our ongoing financial reporting upon adoption.

Off-Balance Sheet Arrangements

As of December 31, 2017, we did not have any off-balance sheet arrangements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The nature of our business and operations is such that no activities or transactions are conducted or entered into by us that would require us to have a discussion under this item.

For a discussion of these matters as they pertain to Antero Midstream, please read Item 7A. “Quantitative and Qualitative Disclosures About Market Risk” of Antero Midstream’s Annual Report on Form 10‑K for the year ended December 31, 2017, which has been included in this filing as Exhibit 99.1 and incorporated herein by reference, as the activities of Antero Midstream have a significant impact on our results of operations and financial position.

The Report of Independent Registered Public Accounting Firm, Consolidated Financial Statements and supplementary financial data required for this Item are set forth beginning on page F‑1 of this report and are incorporated herein by reference.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a15(e) and 15d15(e) under the Exchange Act) as of the end of the period covered by this annual report. Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as December 31, 2017 at a reasonable assurance level.

Management’s Annual Report on Internal Control Over Financial Reporting

This annual report is not required to include a report of management’s assessment regarding internal control over financial reporting or an attestation of our independent public accounting firm due to a transition period established by rules of the SEC for newly public companies.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act) during the fourth quarter of 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

Disclosure pursuant to Section 13(r) of the Securities Exchange Act of 1934

Pursuant to Section 13(r) of the Securities Exchange Act of 1934, we, Antero Midstream GP LP, may be required to disclose in our annual and quarterly reports to the SEC, whether we or any of our “affiliates” knowingly engaged in certain activities, transactions or dealings relating to Iran or with certain individuals or entities targeted by U.S. economic sanctions. Disclosure is generally required even where the activities, transactions or dealings were conducted in compliance with applicable law. Because the SEC defines the term “affiliate” broadly, it includes any entity under common “control” with us (and the term “control” is also construed broadly by the SEC).

The description of the activities below has been provided to us by Warburg, affiliates of which: (i) beneficially own more than 10% of our outstanding common shares and/or are members of our general partner’s board of directors, (ii) beneficially own more than 10% of the equity interests of, and have the right to designate members of the board of directors of Santander Asset Management Investment Holdings Limited (“SAMIH”). SAMIH may therefore be deemed to be under common “control” with us; however, this statement is not meant to be an admission that common control exists.

The disclosure below relates solely to activities conducted by SAMIH and its affiliates. The disclosure does not relate to any activities conducted by us or by Warburg and does not involve our or Warburg’s management. Neither we nor Warburg has had any involvement in or control over the disclosed activities, and neither we nor Warburg has independently verified or participated in the preparation of the disclosure. Neither we nor Warburg is representing as to the accuracy or completeness of the disclosure nor do we or Warburg undertake any obligation to correct or update it.

29


We understand that one or more SEC-reporting affiliates of SAMIH intend to disclose in their next annual or quarterly SEC report that:

(a)Santander UK plc (“Santander UK”) holds two savings accounts and one current account for two customers resident in the United Kingdom (“UK”) who are currently designated by the United States (“US”) under the Specially Designated Global Terrorist (“SDGT”) sanctions program. Revenues and profits generated by Santander UK on these accounts in the year ended December 31, 2017 were negligible relative to the overall revenues and profits of Banco Santander SA.

(b)Santander UK holds two frozen current accounts for two UK nationals who are designated by the US under the SDGT sanctions program. The accounts held by each customer have been frozen since their designation and have remained frozen through the year ended December 31, 2017. The accounts are in arrears (£1,844.73 in debit combined) and are currently being managed by Santander UK Collections & Recoveries department. No revenues or profits were generated by Santander UK on this account in the year ended December 31, 2017.

PART III

Item 10. Directors, Executive Officers, and Corporate Governance

Management of Antero Midstream GP LP

Our general partner, AMGP GP LLC (“AMGP GP”), manages our operations and activities. Our shareholders are limited partners and do not participate in the management of our operations. As a general partner, our general partner is liable for all of our debts (to the extent not paid from our assets), except for indebtedness or other obligations that are made specifically non‑recourse to it. Our general partner has the sole discretion to incur indebtedness or other obligations on our behalf on a non‑recourse basis to the general partner.

We and our general partner have no employees. All of our officers and other personnel necessary for our business to function (to the extent not outsourced) are employed by Antero Resources. As a result, the services agreement provides for our payment of an annual fee to Antero Resources for corporate, general and administrative services. This fee is initially $0.5 million per year and is subject to adjustment on an annual basis based on the CPI. The fee is also subject to adjustment to reflect any increase in the cost of providing services due to changes in applicable law, rules or regulations and any increase in the scope and extent of the services provided. The fee will not be decreased below the initial fee unless the type or extent of services provided materially decreases.

All of our officers and a majority of the directors of our general partner are also officers or directors of Antero Resources and Antero Midstream’s general partner. Our general partner’s executive officers expect to spend the substantial majority of their time managing the business of Antero Midstream and Antero Resources, which benefits us as Antero Midstream’s performance determines our success. We estimate that these officers spend less than 10% of their time on our business, as distinct from Antero Midstream’s and Antero Resources’ businesses. The actual time devoted by these officers to managing our business as well as Antero Midstream’s and Antero Resources’ will fluctuate as a result of the relative activity level between the two entities. The amount of incremental time spent by non‑officer directors who serve on both boards depends to some extent on committee assignments, but our general partner estimates that such directors will spend less than 20% more time by serving on the board of directors of our general partner.

In addition to the fee and expenses described above, we reimburse Antero Resources for costs and expenses to the extent that such costs and expenses are directly allocable to the provision of services to us, our general partner, or our subsidiaries (other than Antero Midstream and its subsidiaries), including recurring costs associated with being a separate publicly traded entity, and taxes, other than payroll taxes, or other direct operating expenses, paid by Antero Resources for our benefit. We will also reimburse our general partner for any additional expenses incurred on our behalf or to maintain our legal existence and good standing. There is no limit on the amount of fees and expenses we may be required to pay to affiliates of our general partner on our behalf pursuant to the services agreement.

Board Leadership Structure

The Board of Directors of AMGP GP (the “Board”) does not have a formal policy addressing whether or not the roles of Chairman and Chief Executive Officer should be separate or combined. The directors serving on the Board possess considerable professional and industry experience, significant experience as directors of both public and private companies and a unique knowledge of the challenges and opportunities that we face. As such, the Board believes that it is in the best position to evaluate our needs and to determine how best to organize our leadership structure to meet those needs.

At present, our Board has chosen to combine the positions of Chairman and Chief Executive Officer. While the Board believes it is important to retain the flexibility to determine whether the roles of Chairman and Chief Executive Officer should be separated or combined in one individual, the Board believes that the current Chief Executive Officer is an individual with the necessary experience, commitment and support of the other members of the Board to effectively carry out the role of Chairman.

The Board believes this structure promotes better alignment of strategic development and execution, more effective implementation of strategic initiatives and clearer accountability for our success or failure. Moreover, the Board

31


believes that combining the Chairman and Chief Executive Officer positions does not impede independent oversight of AMGP. Five of the seven members of the Board are independent under NYSE rules.

Board’s Role in Risk Oversight

In the normal course of our business, we are exposed to a variety of risks. The Board oversees our strategic direction, and in doing so considers the potential rewards and risks of our business opportunities and challenges, and monitors the development and management of risks that impact our strategic goals.

Executive Sessions

To facilitate candid discussion among our directors, the non-management directors meet in regularly scheduled executive sessions. The director who presides at these meetings is chosen by the Board prior to such meetings.

Interested Party Communications

Shareholders and other interested parties may communicate by writing to: Antero Midstream GP LP, 1615 Wynkoop Street, Denver, Colorado 80202. Shareholders may submit their communications to the Board, any committee of the Board or individual directors on a confidential or anonymous basis by sending the communication in a sealed envelope marked "Shareholder Communication with Directors" and clearly identify the intended recipient(s) of the communication.

Our Chief Administrative Officer will review each communication and other interested parties and will forward the communication, as expeditiously as reasonably practicable, to the addressee if: (1) the communication complies with the requirements of any applicable policy adopted by the Board relating to the subject matter of the communication; and (2) the communication falls within the scope of matters generally considered by the Board. To the extent the subject matter of a communication relates to matters that have been delegated by the Board to a committee or to an executive officer of the general partner, then the general partner’s Chief Administrative Officer may forward the communication to the executive officer or chairman of the committee to which the matter has been delegated. The acceptance and forwarding of communications to the members of the Board or an executive officer does not imply or create any fiduciary duty of the Board members or executive officer to the person submitting the communications.

Information may be submitted confidentially and anonymously, although we may be obligated by law to disclose the information or identity of the person providing the information in connection with government or private legal actions and in other circumstances. Our policy is not to take any adverse action, and not to tolerate any retaliation, against any person for asking questions or making good faith reports of possible violations of law, our policies or our Corporate Code of Business Conduct and Ethics.

Available Governance Materials

The Board has adopted the following materials, which are available on our website at www.anteromidstreamgp.com:

·

Charter of the Audit Committee of the Board of Directors;

·

Corporate Code of Business Conduct and Ethics;

·

Shareholders may obtain a copy, free of charge, of each of these documents by sending a written request to Antero Midstream GP LP, 1615 Wynkoop Street, Denver, Colorado, 80202. We intend to disclose any amendments to, or waivers from, our Code of Business Conduct and Ethics on our website.

Directors and Executive Officers

The following table shows information for our general partner’s executive officers and directors. Directors hold office until their successors have been elected or qualified or until the earlier of their death, resignation, removal or disqualification. Executive officers serve at the discretion of the board. There are no family relationships among any of the directors or executive officers. Some of the directors and all of the executive officers also serve as executive officers of Antero Resources and Antero Midstream’s general partner.

Prior to her retirement in March 2014, Ms. Robeson was Senior Vice President & Chief Financial Officer of DCP Midstream GP, LLC, the general partner of DCP Midstream Partners, LP from May 2012 until January 2014.

She also has significant financial management, risk management and accounting oversight experience, which is important in the oversightpreparation of our financial reporting and risk management functions.

We believe her background and skill set make Ms. Robeson well‑suited to serve as a member of our board of directors and as Chairman of the audit committee.

Committees of the Board of Directors

The board of directors of our general partner has an audit committee. We do not have a compensation committee, but rather the board of directors of our general partner approves equity grants to directors and Antero Resources employees. The board of directors of our general partner may establish a conflicts committee to review specific matters that the board believes may involve conflicts of interest.

Audit Committee

Rules implemented by the NYSE and SEC require us to have an audit committee comprised of at least three directors who meet the independence and experience standards established by the NYSE and the Exchange Act, subject to transitional relief during the year following our IPO. Messrs. Levy and Klimley serve on our audit committee, and Ms. Robeson serves as the Chairman of the committee. As required by the rules of the SEC and listing standards of the NYSE, the audit committee currently consists of a majority of independent directors under the standards established by the NYSE and the Exchange Act and will consist solely of independent directors within one year of our IPO. SEC rules also require that a public company disclose whether or not its audit committee has an “audit committee financial expert” as a member. An “audit committee financial expert” is defined as a person who, based on his or her experience, possesses the attributes outlined in such rules. Our board of directors believes that Ms. Robeson possesses substantial financial experience based on her extensive experience in finance as it relates to the oil and gas industry as the former CFO of DCP Midstream LLC. As a result of these qualifications, we believe Ms. Robeson satisfies the definition of “audit committee financial expert.”

This committee oversees, reviews, acts on and reports on various auditing and accounting matters to our board of directors, including: the selection of our independent accountants, the scope of our annual audits, fees to be paid to the independent accountants, the performance of our independent accountants and our accounting practices. In addition, the audit committee oversees our compliance programs relating to legal and regulatory requirements. We adopted an audit committee charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and NYSE.

Conflicts Committee

Our general partner may, from time to time, have a conflicts committee to which the board will appoint at least two independent directors and which may be asked to review specific matters that the board believes may involve conflicts of interest and determines to submit to the conflicts committee for review. The conflicts committee will determine if the

36


resolution of the conflict of interest is adverse to the interest of the partnership. The members of the conflicts committee may not be officers or employees of our general partner or directors, officers or employees of its affiliates, Antero Resources, and must meet the independence standards established by the NYSE and the Exchange Act to serve on an audit committee of a board of directors, along with other requirements in our partnership agreement. Any matters approved by the conflicts committee will be conclusively deemed to be approved by us and all of our partners and not a breach by our general partner of any duties it may owe us or our unitholders.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires executive officers and managing board members of our general partner and persons who beneficially own more than 10% of a registered class of our equity securities to file reports of ownership and changes in ownership with the SEC and to furnish us with copies of all such reports.

Based solely upon our review of reports received by us, or representations from certain reporting persons that no filings were required, we believe that all of the officers and managing board members of our general partner and persons who beneficially owned more than 10% of our common units complied with all applicable filing requirements during fiscal year 2017.

The elements of compensation provided by Antero Resources and the Compensation Committee’s decisions with respect to our Named Executive Officers’ compensation are not subject to approval by the board of directors of our general partner. Certain members of the board of directors of our general partner are members of the board of directors of Antero Resources. Messrs. Kagan, Keenan and Levy served on the board of directors of our general partner and the board of directors of Antero Resources in 2017. As used in this Item 11 (other than in this “Overview” and the “Compensation of Directors” section below), references to “our,” “we,” “us,” the “Company,” and similar terms refer to Antero Resources, references to the “Board” or “Board of Directors” refer to the board of directors of Antero Resources, and references to the Partnership refer to Antero Midstream.

The amounts in this column may differ from those reported above under “Compensation Discussion and Analysis—Elements of Direct Compensation—Base Salaries” due to the fact that adjustments to the base salaries of our Named Executive Officers for the 2016 and 2017 fiscal years took effect on March 1, 2016, and March 1, 2017, respectively.

In December 2016, Messrs. Rady and Warren were each issued Series B Units in IDR LLC, two-thirds of which were unvested as of December 31, 2017. Mr. Kennedy was granted Series B Units in IDR LLC on January 10, 2017, two-thirds of which were unvested as of December 31, 2017. As discussed below under the heading “Payments Upon Termination or Change in Control—Series B Units in IDR LLC,” the Series B Units in IDR LLC are intended to constitute “profits interests” for federal tax purposes. Accordingly, if IDR LLC had been liquidated as of the date these Series B Units were granted, Messrs. Rady, Warren and Kennedy would not have been entitled to receive any distributions with respect to such Series B Units. Please see “Narrative Disclosure to

Narrative Disclosure to Summary Compensation Table

The following is a discussion of material factors necessary to an understanding of the information disclosed in the Summary Compensation Table.

Elements of Direct Compensation

Our Named Executive Officers’ compensation includes the following key components:

·

Base salaries;

·

Annual cash incentive payments; and

·

Long-term equity-based incentive awards.

Base Salaries

Base salaries are designed to provide a minimum, fixed level of cash compensation for services rendered during the year. Base salaries are reviewed annually, but are not necessarily increased if the Compensation Committee believes that (1) our executives are currently compensated at proper levels in light of Company performance or external market factors, or (2) an increase or addition to other elements of compensation would be more appropriate in light of our objectives.

Annual Cash Incentive Awards

Purpose and Operation

Annual cash incentive payments, which we also refer to as cash bonuses, are a key component of each Named Executive Officer’s annual compensation package. This annual incentive plan is based on a balanced scorecard that is used to measure our performance. The bonus targets for each of the Named Executive Officers, which are expressed as a percentage of base salary, are listed below:

2017 Scorecard Results

Although our actual performance indicated a payout calculation of 132%, the Compensation Committee determined that payouts under the 2017 annual incentive scorecard should be capped at 80% of target for Messrs. Rady and Warren and 100% of target for Messrs. Schopp, Kilstrom, McNeilly and Kennedy. The Compensation Committee elected for the 2017 bonuses to be paid in March 2018.

Long-Term Equity-Based Incentive Awards

Restricted Stock Unit Awards and Performance Share Units

The Compensation Committee granted restricted stock unit awards and performance share unit awards under the Antero Resources Corporation Long-Term Incentive Plan (the “AR LTIP”) to each of our Named Executive Officers in April 2017. The restricted stock unit awards will vest pro rata on each of the first four anniversaries of the date of grant. The performance share unit awards will be earned based upon our three-year total shareholder return relative to our selected peer group, as described below. In each case, the applicable Named Executive Officer must remain continuously employed by us from the grant date through the applicable vesting date. All of the restricted stock units and performance share unit awards will also vest in full upon a termination of a Named Executive Officer’s employment due to his death or disability.

The performance share units awarded in 2017 will be earned, if at all, based upon the Company’s three-year total shareholder return performance measured against a selected peer group of onshore publicly traded oil and gas companies that are reasonably similar to us in terms of size and operations. In order to achieve a payout under the performance share unit awards, our total shareholder return performance relative to the peer group over the performance period must rank at or above the 30th percentile for a threshold payout, the 55th percentile for a target payout, or the 80th percentile for the maximum payout. The payout will be determined as follows:

*

Regardless of our relative ranking, if our total shareholder return is negative for the performance period, the number of performance share units earned will not exceed 100% of target. If our relative total shareholder return percentile ranking falls between performance levels, the performance payout percentage will be determined by linear interpolation between such performance levels.

Vested restricted stock units (less any restricted stock units withheld to satisfy applicable tax withholding obligations) will be settled through the issuance of common stock within 30 days following the vesting date. Named Executive Officers holding unvested restricted stock units are entitled to receive dividend equivalent right credits (the “AR DERs”), if any, equal to cash distributions paid in respect of a share of our common stock. The AR DERs will be paid in cash within 30 days following the vesting of the associated restricted stock units, or, if applicable, will be forfeited at the

42


same time the associated restricted stock units are forfeited. The potential acceleration and forfeiture events related to these restricted stock units are described in greater detail under the heading “Potential Payments Upon Termination or Change in Control” below.

Phantom Unit Awards

On April 15, 2017, the board of directors of the general partner of the Partnership granted phantom units under the Midstream LTIP to each of our Named Executive Officers in connection with the Company’s annual compensation program to recognize the Named Executive Officers’ contributions to the operations of the Partnership. Phantom units granted under the Midstream LTIP generally represent the right to receive common units of the Partnership upon vesting. The phantom unit awards granted to our Named Executive Officers will vest, in four equal installments, on each of the first four anniversaries of the grant date so long as the applicable Named Executive Officer remains continuously employed by us from the grant date through the applicable vesting date. All of the phantom units granted to a Named Executive Officer will become fully vested immediately if such Named Executive Officer’s employment terminates due to death or disability or the consummation of a change in control (as defined in the Midstream LTIP). Vested phantom units (less any phantom units withheld to satisfy applicable tax withholding obligations) will be settled through the issuance of common units within 30 days following the vesting date. Named Executive Officers holding unvested phantom units are entitled to receive distribution equivalent right credits (the “Midstream DERs”) equal to cash distributions paid in respect of a common unit of the Partnership. The Midstream DERs will be paid in cash within 30 days following the vesting of the associated phantom units, or, if applicable, will be forfeited at the same time the associated phantom units are forfeited. The potential acceleration and forfeiture events relating to these phantom units are described in greater detail under the heading “Potential Payments Upon Termination or Change in Control” below.

Series B Units in IDR LLC

IDR LLC was formed to hold 100% of the Partnership’s IDRs. As of December 31, 2017, Messrs. Rady, Warren and Kennedy held 48,000, 32,000 and 4,000, respectively, of the 98,600 outstanding Series B Units in IDR LLC. To the extent vested, the Series B Units in IDR LLC entitle the holders thereof to receive, subject to the terms and provisions of the limited liability company agreement of IDR LLC (the “IDR LLC Agreement”) and the incentive unit award agreements pursuant to which the awards were granted, a proportionate amount of up to 6% of any future profits of IDR LLC that result from any distributions on the Partnership’s IDRs that are held by IDR LLC in excess of $7.5 million per quarter. Unvested Series B Units in IDR LLC are not entitled to receive any distributions; however, in connection with any subsequent distribution on the Partnership’s IDRs following the date an unvested Series B Unit in IDR LLC becomes vested, the holder of such vested Series B Unit in IDR LLC is entitled to receive an additional distribution equal to the aggregate amount of distributions that would have been made with respect to such Series B Unit in IDR LLC during the period in which such Series B Unit was unvested if such Series B Unit had been vested.

With respect to vested Series B Units in IDR LLC, Messrs. Rady, Warren and Kennedy have the right, upon delivery of notice to IDR LLC, to require IDR LLC to redeem all or a portion of their vested Series B Units for a number of newly issued AMGP common shares, equal to the quotient determined by dividing (a) the product of (i) the Per Vested B Unit Entitlement (as defined below) and (ii) the number of vested Series B Units being redeemed, by (b) the volume-weighted average price of an AMGP common share for the 20 trading days ending on and including the trading day prior to the date of such notice (the “AMGP VWAP Price”).  However, in no event will the aggregate number of AMGP common shares issued by AMGP pursuant to all such redemptions by owners of Series B Units exceed 6% of the aggregate number of issued and outstanding AMGP common shares. 

For purposes of the redemption right described above, the “Per Vested B Unit Entitlement” is calculated in accordance with the IDR LLC Agreement, and will equal, as of the date of determination, the quotient obtained by dividing (a) the product of (i) the fair market value of IDR LLC (which for this purpose is based on the equity value of AMGP calculated on the applicable date of determination by multiplying the AMGP VWAP Price and the number of then-outstanding AMGP common shares) as of such date minus $2.0 billion and (ii) the product of (A) 6%, (B) the percentage of authorized Series B Units that are outstanding at such time and (C) the percentage of outstanding Series B Units that have vested, by (b) the total number of vested Series B Units outstanding at such time.  In addition, upon the earliest to occur of (x) December 31, 2026, (y) a change of control transaction of AMGP or of IDR LLC, or (z) a liquidation of IDR

43


LLC, AMGP may redeem each outstanding Series B Unit in exchange for AMGP common shares in accordance with the ratio described above, subject to certain limitations.

The remaining unvested Series B Units in IDR LLC issued to Messrs. Rady and Warren on December 31, 2016, will become vested in two equal installments on December 31 of each of 2018 and 2019, so long as the applicable executive remains continuously employed by us or one of our affiliates through each vesting date. The remaining unvested Series B Units in IDR LLC issued to Mr. Kennedy on January 10, 2017 will become vested in two equal installments on December 31 of each of 2018 and 2019, so long as Mr. Kennedy remains continuously employed by us or one of our affiliates through each vesting date. The potential acceleration and forfeiture events relating to these units are described in greater detail under the heading “Potential Payments Upon Termination or Change of Control” below.

Other Benefits

Employment Agreements

We do not maintain any employment, severance or change-in-control agreements with any of our Named Executive Officers.

Health and Welfare Benefits

Our Named Executive Officers are eligible to participate in all of our employee health and welfare benefit arrangements on the same basis as other employees (subject to applicable law). These arrangements include medical, dental and disability insurance, as well as health savings accounts. We provide these benefits in order to ensure that we can competitively attract and retain officers and other employees. This is a fixed component of compensation, and these benefits are provided on a non-discriminatory basis to all employees.

Retirement Benefits

We maintain an employee retirement savings plan through which employees may save for retirement or future events on a tax-advantaged basis. Participation in the 401(k) plan is at the discretion of each individual employee, and our Named Executive Officers participate in the plan on the same basis as all other employees. The plan permits us to make discretionary matching and non-elective contributions. Since January 1, 2014, the Company has matched 100% of the first 4% of eligible compensation that employees contribute to the plan. Matching contributions provided by the Company are immediately fully vested.

Perquisites and Other Personal Benefits

We believe the total mix of compensation and benefits provided to our Named Executive Officers is currently competitive. Therefore, perquisites do not play a significant role in our Named Executive Officers’ total compensation.

The equity awards that are disclosed in this Outstanding Equity Awards at 2017 Fiscal Year-End table under Option Awards are (i) stock option awards granted under the AR LTIP and (ii) for Messrs. Rady, Warren and Kennedy, Series B Units in IDR LLC that are intended to constitute profits interests for federal tax purposes rather than traditional option awards.

(2)

Awards reflected as “Unexercisable” are Series B Units in IDR LLC and stock option awards that have not yet vested.

45


(3)

One-half of the unvested stock option awards reflected in this row will become vested and exercisable on each of April 15, 2018, and April 15, 2019, so long as the applicable Named Executive Officer remains continuously employed by us or one of our affiliates through each such date.

(4)

For Messrs. Rady, Warren and Kennedy, one-half of the unvested Series B Units in IDR LLC reflected in this row will become vested and exercisable on each of December 31, 2018, and December 31, 2019, so long as the applicable Named Executive Officer remains continuously employed by us or one of our affiliates through each such date.

(5)

These equity awards are not traditional options and, therefore, there is no exercise price or expiration date associated with them.

(6)

The equity awards that are disclosed in this Outstanding Equity Awards at 2017 Fiscal Year-End table under the Stock Awards column consist of the following awards granted under the AR LTIP: (i) restricted stock units, (ii) performance share units, and (iii) performance share units granted as special retention awards to Messrs. Schopp, Kilstrom and McNeilly in February 2016 for which the applicable stock price hurdle has been achieved. This Stock Awards column also includes phantom units granted under the Midstream LTIP.

(7)

Except as otherwise provided in the applicable award agreement, (1) 2016 restricted stock unit awards will vest on April 15 of each of 2018, 2019 and 2020, (2) 2015 restricted unit awards will vest on April 15 of each of 2018 and 2019, (3) the  restricted stock units granted in 2014 to Messrs. Schopp, Kilstrom, and McNeilly will vest on April 1, 2018, (4) phantom units granted in 2016 will vest on April 15 of each of 2018, 2019 and 2020, (5) the phantom units granted in 2014 will vest on November 12, 2018, (6) performance share unit awards granted in 2016 will vest following the Committee’s determination of our relative three-year total shareholder return achievement for the performance period ending April 15, 2019, and (7) the 2016 performance share units granted as special retention awards to Messrs. Schopp, Kilstrom and McNeilly for which the applicable stock price hurdle has been achieved will vest in equal increments on February 8 of each of 2018 and 2019, in each case, so long as the applicable Named Executive Officer remains continuously employed by us from the grant date through the applicable vesting date.

(8)

The amounts reflected in this column represent the market value of (i) common stock underlying the restricted stock unit awards granted to the Named Executive Officers, computed based on the closing price of our common stock on December 31, 2017, which was $19.00 per share, (ii) common stock underlying the target number of performance share units granted to the Named Executive Officers, computed in accordance with FASB ASC Topic 718, and (iii) common units of the Partnership underlying the phantom unit awards granted to the Named Executive Officers, computed based on the closing price of the Partnership’s common units on December 31, 2017, which was $29.04 per unit. See Note 4 to our consolidated financial statements for additional detail regarding assumptions underlying the value of these equity awards.

Payments Upon Termination or Change in Control

Restricted Stock Units, Phantom Units and Stock Options

Any unvested restricted stock units, unvested phantom units or unvested stock options subject to time-based vesting criteria granted to our Named Executive Officers under the AR LTIP or the Midstream LTIP, as applicable, will become immediately fully vested (and, in the case of stock options, fully exercisable) if the applicable Named Executive Officer’s employment with us terminates due to his death or “disability” or in the event of a “change in control” (as such terms are defined in the AR LTIP or the Midstream LTIP, as applicable). For performance share unit awards, any continued employment conditions will be deemed satisfied on the date of the applicable Named Executive Officer’s termination due to his death or “disability” or upon the occurrence of a “change in control,” the performance period will end on the date of such termination or “change in control,” and such performance share unit awards will be settled based on the actual level of performance achieved as of such date.

For purposes of these awards, a Named Executive Officer will be considered to have incurred a “disability” if the executive is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or which has lasted or can be expected to last for a continuous period of at least 12 months.

For purposes of the AR LTIP awards, “change in control” generally means the occurrence of any of the following events:

·

A person or group of persons acquires beneficial ownership of 50% or more of either (a) the outstanding shares of our common stock or (b) the combined voting power of our voting securities entitled to vote in the

46


election of directors, in each case with the exception of (i) any acquisition directly from us, (ii) any acquisition by us or any of our affiliates, or (iii) any acquisition by any employee benefit plan sponsored or maintained by us;

·

The incumbent members of the Board cease for any reason to constitute at least a majority of the Board;

·

The consummation of a reorganization, merger or consolidation, or sale or other disposition of all or substantially all of our assets, or an acquisition of assets of another entity (a “Business Combination”), in each case, unless, following such Business Combination, (A) our outstanding common stock immediately prior to such Business Combination represents more than 50% of the outstanding common equity interests and the outstanding voting securities entitled to vote in the election of directors of the surviving entity, (B) no person or group of persons beneficially owns 20% or more of the common equity interests of the surviving entity or the combined voting power of the voting securities entitled to vote generally in the election of directors of such surviving entity, and (C) at least a majority of the members of the board of directors of the surviving entity were members of the incumbent board at the time of the execution of the initial agreement or corporate action providing for such Business Combination; or

·

Approval by our shareholders of a complete liquidation or dissolution of the Company.

For purposes of the Midstream LTIP awards, “change in control” means the occurrence of any of the following events:

·

A person or group of persons, other than certain affiliates of the Partnership, becomes the beneficial owner, by way of merger, acquisition, consolidation, recapitalization, reorganization, or otherwise, of 50% or more of the voting power of the equity interests in the general partner of the Partnership;

The sale or disposition by either the Partnership or the general partner of the Partnership of all or substantially all of its assets;

·

A “Change in Control” as defined in the AR LTIP.

Series B Units in IDR LLC

The Series B Units in IDR LLC held by Messrs. Rady, Warren and Kennedy will vest upon the consummation of a change of control transaction (as defined in the IDR LLC Agreement) or upon an involuntary termination without cause or due to death or disability. As discussed above, the Series B Units in IDR LLC issued to Messrs. Rady and Warren on December 31, 2016 and to Mr. Kennedy on January 10, 2017 are intended to constitute “profits interests” for federal tax purposes and are not traditional options.

As used in the IDR LLC Agreement and the award agreements pursuant to which the Series B Units in IDR LLC were granted, “change of control transaction” means the occurrence of any of the following events:

·

Any consolidation, conversion, merger or other business combination involving IDR Holdings or AMGP, in which a majority of the outstanding Series A Units of IDR LLC or a majority of the outstanding common shares of AMGP (the “AMGP common shares”) are exchanged for or converted into cash, securities of a corporation or other business organization, or other property;

47


·

A sale or other disposition of all or a material portion of the assets of IDR LLC;

·

A sale or other disposition of all or substantially all of the assets of AMGP followed by a liquidation of AMGP or a distribution to the members of AMGP of all or substantially all of the net proceeds of such disposition after payment of liabilities and other obligations of AMGP;

·

The sale by all the members of IDR LLC of all or substantially all of the outstanding IDR LLC membership interests in a single transaction or series of related transactions; or

·

The sale of all of the outstanding AMGP common shares in a single transaction or series of related transactions.

As discussed above, each of Messrs. Rady, Warren and Kennedy have the right, upon delivery of written notice to IDR LLC, to require IDR LLC to redeem all or a portion of their vested Series B Units for a number of newly issued AMGP common shares, determined in accordance with the formula described in “Narrative Disclosure to Summary Compensation Table—Long-Term Equity-Based Incentive Awards—Series B Units in IDR LLC” above.

The above mechanisms are subject to customary conversion rate adjustments for equity splits, equity dividends and reclassifications.

Our non-employee directors are entitled to receive compensation consisting of retainers, fees and equity awards as described below. The Compensation Committee reviews and approves non-employee director compensation on a periodic basis.

Our employee directors, Messrs. Rady and Warren, do not receive additional compensation for their services as directors. All compensation that Messrs. Rady and Warren received from the Company as employees is disclosed in the Summary Compensation Table above.

Messrs. Kagan, Keenan and Levy have agreed or are otherwise obligated to transfer all or a portion of the compensation they receive for their service as directors to the Sponsor with which they are affiliated.

All retainers are paid in cash on a quarterly basis in arrears, but directors have the option to elect, on an annual basis, to receive all or a portion of their retainers in the form of shares of our common stock. Directors do not receive any meeting fees, but each director is reimbursed for (1) travel and miscellaneous expenses to attend meetings and activities of the Board or its committees, and (2) travel and miscellaneous expenses related to the director’s participation in general education and orientation programs for directors.

Kagan, Keenan and Levy are required to hold shares of our common stock with a fair market value equal to at least five times the amount of their annual cash retainer.

Item 13. Certain Relationships and Related Transactions and Director Independence

Our Related Party Transactions

Limited Liability Company Agreement of Our General Partner

Our general partner’s limited liability company agreement provides for the designation of members of the board of directors of our general partner by our Sponsors, including Mr. Rady, our Chairman, Chief Executive Officer and a member of the board of directors of our general partner, and Mr. Warren, our President and Secretary and a member of the board of directors of our general partner.

Pursuant to the terms of the limited liability company agreement of our general partner, during the ten‑year period commencing with the closing of our IPO, if either Mr. Rady or Mr. Warren serves as an executive officer or in an active role in the management of any company (other than AMGP, Antero Resources, Antero Midstream or their respective subsidiaries and joint ventures) that is primarily engaged in an operating oil and gas exploration, production, gathering, compression or water handling and treatment business, then such individual (or his designee) will be removed as a member of the board of directors of our general partner and such individual will no longer be entitled to designate a member of the board of directors of our general partner.

Limited Liability Company Agreement of IDR LLC

On December 31, 2016, our Predecessor entered into the limited liability company agreement of Antero IDR Holdings LLC, pursuant to which IDR LLC created two classes of membership interests, including capital interests referred to as Series A Units and profits interests referred to as Series B Units. We own all of the Series A Units and the Series B Holders will continue to own all of the Series B Units.

The Series B Units are subject to restrictions on transfer and vest in three annual installments in one‑third increments upon each anniversary of the vesting commencement date, subject to the holder’s continuous service with us and our affiliates through the vesting commencement date. Series B Units will also vest in full upon a change in control of us or IDR LLC or upon a termination by us or our applicable affiliate of the holder’s service with us and our affiliates without cause or due to the holder’s death or disability. In the event any Series B Units fail to vest, they will be forfeited to IDR LLC and may not be re‑issued.

The IDR LLC Agreement has been filed as an exhibit to this Form 10-K, and the foregoing description of the IDR LLC limited liability company agreement is qualified in its entirety by reference thereto.

Cash Distributions

Our sole cash‑generating asset consists of our interest in IDR LLC, which owns all of the IDRs of Antero Midstream. Through our ownership interest in IDR LLC, our shareholders will be entitled to a portion of the cash distributions paid by Antero Midstream on its IDRs. We expect to receive at least 94% of the cash distributions paid by Antero Midstream on the IDRs.

We will pay to our shareholders, on a quarterly basis, distributions equal to the cash we receive from IDR LLC, less distributions paid to or reserved for the Series B Holders, taxes and other expenses, including reserves relating to our general and administrative expenses (including expenses we will incur as the result of being a public company) and reserves that our general partner (on our behalf as the managing member of IDR LLC) believes prudent to pay or provide for payment of existing and projected obligations and to provide a reasonable reserve for working capital and contingencies. If the distribution on the IDRs exceeds such amount, the Series B Holders will receive an aggregate distribution of up to 6% of the excess amount distributed on the IDRs with respect to such fiscal quarter, and we will receive all remaining distributions. The Series B Units are subject to restrictions on transfer and vest ratably over a three‑year period upon each anniversary of the vesting commencement date. The Series B Holders are entitled to distributions only with respect to Series B Units that are vested. Any distributions that would otherwise be made with respect to a Series B Unit that is unvested will instead be made to the holders of Series A Units.

55


As Series B Units vest, each holder of such vested Series B Units will be entitled to receive a make‑whole distribution corresponding to the aggregate amount of distributions such holder would have received on such Series B Units had they been vested on the vesting commencement date prior to IDR LLC making any distributions in respect of the other IDR LLC units. The payment of these make‑whole distributions to the holders of the Series B Units will be paid out of the quarterly distribution for the fiscal quarter following the vesting date and will lower the amount of cash paid on the Series A Units until the full amount of the make‑whole distribution has been paid. In anticipation of such make‑whole distributions, each quarter we expect to retain from the cash distributions we receive on the Series A Units an amount equal to the portion of the future make‑whole distributions attributable to that quarter. Accordingly, when IDR LLC pays a make‑whole distribution to a holder of newly‑vested Series B Units that reduces the amount otherwise payable on our Series A Units, we will supplement the lower distributions we receive with the cash retained in prior periods so that our distributions remain constant.

In addition, the holders of interests in IDR LLC, including us, will be subject to tax on their proportionate share of any taxable income of IDR LLC and will be allocated their proportionate share of any taxable loss of IDR LLC.

For the year ended December 31, 2017, we received distributions of approximately $53.5 million pursuant to the terms of the IDR LLC agreement.

Redemption Right

Each of the Series B Holders will have the right, upon delivery of written notice to IDR LLC, to require IDR LLC to redeem all or a portion of such holder’s vested Series B Units for a number of our newly‑issued common shares equal to the quotient determined by dividing (a) the product of (i) the Per Vested B Unit Entitlement and (ii) the number of vested Series B Units being redeemed by (b) the volume weighted average price of a common share for the 20 trading days ending on and including the trading day prior to the date of such notice, which we refer to as the “AMGP VWAP Price”; provided, however, that, in no event will the aggregate number of common shares issued by us pursuant to such redemptions exceed 6% of the aggregate number of issued and outstanding common shares. The Per Vested B Unit Entitlement will be calculated in accordance with the IDR LLC Agreement from time to time and will equal, as of a date of determination, the quotient obtained by dividing (a) the product of (i) the fair market value of IDR LLC (which for this purpose is based on our equity value and which shall be calculated on any date of determination by multiplying the AMGP VWAP Price and the number of then‑outstanding common shares) as of such date minus $2.0 billion and (ii) the product of (A) 6%, (B) the percentage of authorized Series B Units that are outstanding and (C) the percentage of outstanding Series B Units that have vested by (b) the total number of vested Series B Units outstanding at such time.

In addition, upon the earliest to occur of (a) December 31, 2026, (b) a change of control of us or of IDR LLC or (c) a liquidation of IDR LLC, our general partner (on our behalf in our capacity as the managing member of IDR LLC) may redeem each outstanding Series B Unit in exchange for our common shares in accordance with the ratio described above, subject to certain limitations.

The above mechanisms are subject to customary conversion rate adjustments for equity splits, equity dividends and reclassifications.

Services Agreement

We, our general partner, IDR LLC and Antero Resources have entered into a services agreement, which govern, among other things, certain administrative services that Antero Resources will provide to us.

Administrative Services and Fees

We and our general partner have no employees. All of our officers and other personnel necessary for our business to function (to the extent not outsourced) are employed by Antero Resources, and we pay Antero Resources an annual fee for corporate, general and administrative services. This fee is initially $0.5 million per year and is subject to adjustment on an annual basis based on the CPI. The fee is also subject to adjustment to reflect any increase in the cost of providing services due to changes in applicable law, rules or regulations and any increase in the scope and extent of the services

56


provided. The fee will not be decreased below the initial fee unless the type or extent of services provided materially decreases.

In addition to the fee and expenses described above, we will reimburse Antero Resources for costs and expenses to the extent that such costs and expenses are directly allocable to the provision of services to us, our general partner, or our subsidiaries (other than Antero Midstream and its subsidiaries), including recurring costs associated with being a separate publicly traded entity, and taxes, other than payroll taxes, or other direct operating expenses, paid by Antero Resources for our benefit. We will also reimburse our general partner for any additional expenses incurred on our behalf or to maintain our legal existence and good standing. There is no limit on the amount of fees and expenses we may be required to pay to affiliates of our general partner on our behalf pursuant to the services agreement.

For the year ended December 31, 2017, we reimbursed Antero Resources for approximately $1.5 million of its direct and allocated indirect expenses under the services agreement.

License of Names and Marks

Pursuant to the services agreement, Antero Midstream has also granted us a license to use the names “Antero Midstream” and any associated or related marks.

Registration Rights Agreement

We have entered into a registration rights agreement with the Sponsors and certain of our affiliates. Pursuant to the registration rights agreement, we have agreed to register the resale of all common shares held by the Sponsors and certain of our affiliates or issuable to them upon the redemption of Series B Units (the “AMGP Registrable Securities”) under certain circumstances. Additionally, if necessary, upon the vesting of additional Series B Units held by a Series B Holder, we have agreed to amend the registration rights agreement to include any common shares issuable upon the redemption of vested Series B Units for our common shares as AMGP Registrable Securities, so long as the holder of such units agrees to be bound by the terms and conditions of the registration rights agreement.

Demand Registration Rights

At any time after the six month anniversary of the IPO, each Sponsor that, together with its affiliates, owns at least 3% of our outstanding common shares has the right to require us by written notice to register the sale of a number of their AMGP Registrable Securities in an underwritten offering. We are required to provide notice of the request within 10 days following the receipt of such demand request to all additional holders of AMGP Registrable Securities, if any, who may, in certain circumstances, participate in the registration. We are not obligated to effect any demand registration in which the anticipated aggregate offering price included in such offering is less than $50,000,000. Once we are eligible to effect a registration on Form S‑3, any such demand registration may be for a shelf registration statement.

Piggyback Registration Rights

If, at any time, we propose to register an offering of our securities (subject to certain exceptions) for our own account, then we must give each holder of AMGP Registrable Securities the opportunity to allow such holder to include a specified number of AMGP Registrable Securities in that registration statement.

Redemptive Offerings

We may be required pursuant to the registration rights agreement to undertake a future public or private offering and use the proceeds (net of underwriting or placement agency discounts, fees and commissions, as applicable) to redeem an equal number of common units from the holders of AMGP Registrable Securities.

57


Conditions and Limitations; Expenses

The registration rights are subject to certain conditions and limitations, including the right of the underwriters to limit the number of AMGP Registrable Securities to be included in a registration and our right to delay or withdraw a registration statement under certain circumstances. We will generally pay all registration expenses in connection with our obligations under the registration rights agreement, regardless of whether a registration statement is filed or becomes effective. The obligations to register AMGP Registrable Securities under the registration rights agreement will terminate when no AMGP Registrable Securities remain outstanding. AMGP Registrable Securities shall cease to be covered by the registration rights agreement when they have (i) been sold pursuant to an effective registration statement under the Securities Act, (ii) been sold in a transaction exempt from registration under the Securities Act (including transactions pursuant to Rule 144), (iii) ceased to be outstanding, (iv) been sold in a private transaction in which Antero Resources’ rights under the registration rights agreement are not assigned to the transferee or (v) become eligible for resale pursuant to Rule 144(b) (or any similar rule then in effect under the Securities Act).

Procedures for Review, Approval and Ratification of Transactions with Related Persons

The Board has adopted a written code of business conduct and ethics, under which a director would be expected to bring to the attention of our chief executive officer or the board any conflict or potential conflict of interest that may arise between the director or any affiliate of the director, on the one hand, and us or our general partner on the other. The resolution of any such conflict or potential conflict should, at the discretion of the board in light of the circumstances, be determined by a majority of the disinterested directors.

If a conflict or potential conflict of interest arises between our general partner or its affiliates, on the one hand, and us or our unitholders, on the other hand, the resolution of any such conflict or potential conflict should be addressed by the board of directors of our general partner in accordance with the provisions of our partnership agreement. At the discretion of the board in light of the circumstances, the resolution may be determined by the board in its entirety or by the conflicts committee.

Pursuant to our code of business conduct, our general partner’s executive officers are required to avoid conflicts.

Conflicts of Interest

Conflicts of interest exist and may arise in the future as a result of the relationships between our general partner and its directors, officers, affiliates (including Antero Resources) and owners, on the one hand, and us and our limited partners, on the other hand. Conflicts may arise as a result of the duties of our general partner and its directors and officers to act for the benefit of its owners, which may conflict with our interests and the interests of our public unitholders. We are managed and operated by the board of directors and officers of our general partner, AMGP GP, which is owned by our Sponsors. All of our officers and a majority of our directors are officers or directors of Antero Resources. Although our general partner has a contractual duty to manage us in a manner that it believes is not adverse to our interests, the directors and officers of our general partner have a fiduciary duty to manage our general partner in a manner that is beneficial to its owners. Our general partner’s directors and officers who are also directors and officers of Antero Resources have a fiduciary duty to manage Antero Resources in a manner that is beneficial to Antero Resources and its shareholders. Our partnership agreement specifically defines the remedies available to unitholders for actions taken that, without these defined liability standards, might constitute breaches of fiduciary duty under applicable Delaware law. The Delaware Act provides that Delaware limited partnerships may, in their partnership agreements, expand, restrict or eliminate the fiduciary duties otherwise owed by the general partner to the limited partners and the partnership.

Whenever a conflict arises between our general partner or its owners and affiliates (including Antero Resources), on the one hand, and us or our limited partners, on the other hand, the resolution or course of action in respect of such conflict of interest shall be permitted and deemed approved by us and all our limited partners and shall not constitute a

58


breach of our partnership agreement, of any agreement contemplated thereby or of any duty, if the resolution or course of action in respect of such conflict of interest is:

·

approved by the conflicts committee of our general partner, although our general partner is not obligated to seek such approval; or

·

approved by the holders of a majority of the outstanding common units, excluding any such units owned by our general partner or any of its affiliates.

Our general partner may, but is not required to, seek the approval of such resolutions or courses of action from the conflicts committee of its board of directors or from the holders of a majority of the outstanding common units as described above. If our general partner does not seek approval from the conflicts committee or from holders of common units as described above and the board of directors of our general partner approves the resolution or course of action taken with respect to the conflict of interest, then it will be presumed that, in making its decision, the board of directors of our general partner acted in good faith, and in any proceeding brought by or on behalf of us or any of our unitholders, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption and proving that such decision was not in good faith. Unless the resolution of a conflict is specifically provided for in our partnership agreement, the board of directors of our general partner or the conflicts committee of the board of directors of our general partner may consider any factors they determine in good faith to consider when resolving a conflict. An independent third party is not required to evaluate the resolution. Under our partnership agreement, a determination, other action or failure to act by our general partner, the board of directors of our general partner or any committee thereof (including the conflicts committee) will be deemed to be “in good faith” unless our general partner, the board of directors of our general partner or any committee thereof (including the conflicts committee) believed such determination, other action or failure to act was adverse to the interest of the partnership. Please read “Item 10—Committees of the Board of Directors—Conflicts Committee” for information about the conflicts committee of our general partner’s board of directors.

Director Independence

Rather than adopting categorical standards, the Board assesses director independence on a case-by-case basis, in each case consistent with applicable legal requirements and the listing standards of the NYSE. After reviewing all relationships each director has with us, including the nature and extent of any business relationships between us and each director, as well as any significant charitable contributions we make to organizations where our directors serve as board members or executive officers, the Board has affirmatively determined that the following directors have no material relationships with us and are independent as defined by the current listing standards of the NYSE: Messrs. Kagan, Keenan, Klimley, Levy and Ms. Robeson. Neither Mr. Rady, the Chairman and Chief Executive Officer of our general partner, nor Mr. Warren, the President and Secretary of our general partner, is considered by the Board to be an independent director because of his employment with Antero Resources.

INDEX TO CONSOLIDATED FINANCIAL STATEMENTS

F-2


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The shareholders and board of directors

Antero Midstream GP LP:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Antero Midstream GP LP and subsidiaries (the Company) as of December 31, 2016 and 2017, the related consolidated statements of operations and comprehensive income, partners’ capital, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2016 and 2017, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company 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 consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ KPMG LLP

We have served as the Company’s auditor since 2016.

ANTERO MIDSTREAM GP LP

Notes to Consolidated Financial Statements

Years Ended December 31, 2015, 2016, and 2017

(1)   Business and Organization

Antero Midstream GP LP (“AMGP”) was originally formed as Antero Resources Midstream Management LLC (“ARMM”) in 2013 to become the general partner of Antero Midstream Partners LP (“Antero Midstream”), a master limited partnership that is publicly traded on the New York Stock Exchange (NYSE: AM). On May 4, 2017, ARMM converted from a Delaware limited liability company to a Delaware limited partnership and changed its name to Antero Midstream GP LP in connection with our initial public offering (“IPO”). Unless the context otherwise requires, references to “we” and “our” refer to: (i) for the period prior to May 4, 2017, ARMM, and (ii) beginning on May 4, 2017, AMGP. We own 100% of the membership interests of Antero Midstream Partners GP LLC (“AMP GP”), which owns the non-economic general partner interest in Antero Midstream, and we own all of the Series A capital interests (“Series A Units”) in Antero IDR Holdings LLC (“IDR LLC”), which owns the incentive distribution rights (“IDRs”) in Antero Midstream. IDR LLC also has Series B profits interests (“Series B Units”) outstanding that entitle the holders to receive up to 6% of the distributions that Antero Midstream makes on the IDRs in excess of $7.5 million per quarter, subject to certain vesting conditions (see Note 4—Long-Term Incentive Plans). We are taxed as a corporation for U.S. federal income tax purposes and we refer to our outstanding limited partner interests as common shares.

Our only income results from distributions made on the IDRs of Antero Midstream. The Antero Midstream IDRs entitle holders to receive cash distributions from Antero Midstream when distributions exceed certain target amounts (see Note 5 – Distributions from Antero Midstream).

We are managed by our general partner, AMGP GP LLC (“AMGP GP”), which establishes the quarterly cash distribution for our common shares payable to shareholders. AMGP GP has a board of directors appointed by certain former members of Antero Resources Investment LLC (“Antero Investment”), the former sole member of ARMM prior to its liquidation on October 31, 2017. Following the completion of our IPO, certain of our directors and executive officers own AMGP common shares as well as Series B Units in IDR LLC. In addition, certain of our directors and executive officers own a portion of Antero Resources Corporation’s (“Antero Resources”) (NYSE: AR) common stock and Antero Midstream’s common units. We have an agreement with Antero Resources, under which Antero Resources provides general and administrative services to us for a fee of $0.5 million per year, subject to annual inflation adjustments. We also incur recurring direct expenses for the costs associated with being a publicly traded entity.

IDR distributions earned by us through May 9, 2017, net of any related liabilities including income taxes through that date and expenses of the IPO, were distributed to Antero Investment prior to its liquidation.

Antero Midstream was formed by Antero Resources to own, operate and develop midstream energy assets to service Antero Resources’ oil and gas producing assets. Both Antero Midstream and Antero Resources’ assets are located in the Marcellus Shale and Utica Shale located in West Virginia and Ohio. Antero Midstream’s assets consist of gathering pipelines, compressor stations, interests in processing and fractionation plants, and water handling and treatment assets, which provide midstream services to Antero Resources under long term, fixed fee contracts. Antero Midstream also has a 15% equity interest in the gathering system of Stonewall Gas Gathering LLC (“Stonewall”) and a 50% equity interest in the Joint Venture to develop processing and fractionation assets with MarkWest Energy. Our results of operations, financial position and cash flows are dependent on the results of operations, financial position and cash flows of Antero Midstream. As a result, these consolidated financial statements should be read in conjunction with Antero Midstream’s combined consolidated financial statements and notes thereto presented in its Annual Report on Form 10‑K for the year ended December 31, 2017.

F-8


(2)   2—Summary of Significant Accounting Policies

(a)   Basis of Presentation

The accompanying to our consolidated financial statements have been prepared in accordance withfor a discussion of additional accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, the accompanying consolidated financial statements include all adjustments (consisting of normalpolicies and recurring accruals) considered necessary to present fairly our financial position as of December 31, 2016 and 2017, and our results of operations and cash flows for the years ended December 31, 2015, 2016, and 2017. We have no items of other comprehensive income; therefore, our net income or loss is identical to our comprehensive income.estimates made by management.

As of the date these consolidated financial statements were filed with the SEC, AMGP completed its evaluation of potential subsequent events for disclosure and no items requiring disclosure were identified other than as disclosed in Note 6 – Cash Distributions.

(b)   Principles of ConsolidationFair Value Measurement

The consolidated financial statements include the accounts of AMGP, AMP GP (its wholly-owned subsidiary), and IDR LLC.

(c)   Investment in Antero Midstream

We have determined that Antero Midstream is a variable interest entity (“VIE”) for which we are not the primary beneficiary and therefore do not consolidate. We have concluded that Antero Resources is the primary beneficiary of Antero Midstream and should consolidate its financial results. Antero Resources is the primary beneficiary based on its power to direct the activities that most significantly impact Antero Midstream’s economic performance and its obligations to absorb losses or receive benefits of Antero Midstream that could be significant to Antero Midstream. Antero Resources owns approximately 52.9% of the outstanding limited partner interests in Antero Midstream and its officers and management group also act as management of Antero Midstream. Antero Midstream was formed to own, operate and develop midstream energy assets to service Antero Resources’ production under long-term contracts as described herein. We do not own any limited partnership interests in Antero Midstream and have no capital interests in Antero Midstream. We have not provided, and do not anticipate providing, financial support to Antero Midstream.

Antero Resources and Antero Midstream have contracts with 20-year initial terms and automatic renewal provisions, whereby Antero Resources has dedicated the rights for gathering and compression, and water handling and treatment, services to Antero Midstream on a fixed-fee basis. Such dedications cover a substantial portion of Antero Resources’ current acreage and future acquired acreage, in each case, except for acreage that was already dedicated to other parties prior to entering into the service contracts or that was acquired subject to a pre-existing dedication. The contracts call for Antero Resources to present, in advance, drilling and completion plans in order for Antero Midstream to put in place gathering and compression, water handling, and gas processing assets to service Antero Resources’ assets. The drilling and completion capital investment decisions made by Antero Resources control the development and operation of all of Antero Midstream’s assets. Antero Resources therefore controls the activities that most significantly impact Antero Midstream’s economic performance. Because of these contractual obligations and the capital requirements related to these obligations, Antero Midstream has devoted and, for the foreseeable future, will devote substantially all of its resources to servicing Antero Resources’ operations. Additionally, revenues from Antero Resources will provide substantially all of Antero Midstream’s financial support and therefore its ability to finance its operations. Because of the long term contractual commitment to support Antero Resources’ substantial growth plans, Antero Midstream will be practically and physically constrained from providing any significant amount of services to third parties.

Our ownership of the non-economic general partner interest in Antero Midstream provides us with significant influence over Antero Midstream, but not control over the decisions that most significantly impact the economic performance of Antero Midstream. Our indirect ownership of the IDRs of Antero Midstream entitles us to receive cash distributions from Antero Midstream when distributions exceed certain target amounts. Our ownership of these interests does not require us to provide financial support to Antero Midstream. We obtained these interests upon our formation for

F-9


no consideration. Therefore, they have no cost basis and are classified as long term investments. Our share of Antero Midstream’s earnings as a result of our ownership of the IDRs is accounted for using the equity method of accounting. We recognize distributions earned from Antero Midstream as “Equity in earnings of Antero Midstream Partners LP” on our statement of operations in the period in which they are earned and are allocated to our capital account. Our long term interest in the IDRs on the balance sheet is recorded in “Investment in Antero Midstream Partners LP.” The ownership of the general partner interests and IDRs do not provide us with any claim to the assets of Antero Midstream other than the balance in our Antero Midstream capital account. Income related to the IDRs is recognized as earned and increases our capital account and equity investment. When these distributions are paid to us, they reduce our capital account and our equity investment in Antero Midstream. See Note 5—Distributions from Antero Midstream.

(d)   Use of Estimates

The preparation of the consolidated financial statements and notes in conformity with GAAP requires that management formulate estimates and assumptions that affect income, expenses, assets, and liabilities. Changes in facts and circumstances or discovery of new information may result in revised estimates, and actual results could differ from those estimates.

(e)   Income Taxes

We regularly review our tax positions in each significant taxing jurisdiction during the process of evaluating our tax provision. We make adjustments to our tax provision when: (i) facts and circumstances regarding a tax position change, causing a change in management’s judgment regarding that tax position; and/or (ii) a tax position is effectively settled with a tax authority at a differing amount.

(f)   General and Administrative Expenses

General and administrative costs incurred during 2016 and pre-IPO in 2017 primarily relate to legal and other costs incurred in connection with our IPO. Post-IPO general and administrative expense consists primarily of management fees paid to Antero Resources, and other legal and administrative expenses.

(g)   Fair Value Measures

The Financial Accounting Standards Board (the “FASB”) Accounting Standards CodificationFASB ASC Topic 820, Fair Value Measurements and Disclosures, clarifies the definition of fair value, establishes a framework for measuring fair value, and expands disclosuressets forth disclosure requirements about fair value measurements. This guidance also relates to all nonfinancial assets and liabilities that are not recognized or disclosed on a recurring basis (e.g., the initial recognition of asset retirement obligations and impairments of long‑livedlong-lived assets). The fair value is the price that we estimate would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy is used to prioritize inputs to valuation techniques used to estimate fair value. An asset or liability subject to the fair value requirements is categorized within the hierarchy based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The highest priority (Level 1) is given to unadjusted quoted market prices in active markets for identical assets or liabilities, and the lowest priority (Level 3) is given to unobservable inputs. Level 2 inputs are data, other than quoted prices included within Level 1, whichthat are observable for the asset or liability, either directly or indirectly.

(h) Net Income per Common ShareBusiness Combination

We recognize and measure the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date, with any remaining difference recorded as goodwill. For acquisitions, management engages an

independent valuation specialist to assist with the determination of fair value of the assets acquired, liabilities assumed and goodwill, based on recognized business valuation methodologies.  If the initial accounting for each periodthe business combination is computed by dividing net income attributable to common shareholdersincomplete by the basic weighted average numberend of the reporting period in which the acquisition occurs, an estimate will be recorded.  Subsequent to the acquisition, and not later than one year from the acquisition date, we will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the acquisition date. An adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period of the adjustment. Acquisition-related costs are expensed as incurred in connection with each business combination.

We accounted for the Transactions under the acquisition method of accounting and estimated the fair value of assets acquired and liabilities assumed at March 12, 2019. In connection with the Transactions, the Company, among other things, issued shares of common stock valued at the closing market price of the common shares outstanding duringat the period. Neteffective time of the Transactions, which was a Level 1 measurement.

We used the discounted cash flow approach, which is an income per common share – dilutedstatement technique, to estimate the fair value of the customer relationships and investments in unconsolidated affiliates using a weighted-average cost of capital of 14.1%, which is based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair value hierarchy. We also used this approach in combination with the cost approach to estimate the fair value of property and equipment whereby certain property and equipment was adjusted for recent purchases of similar items, economic and functional obsolescence, location, normal useful lives and capacity (if applicable). To estimate the fair value of the long-term debt, we used Level 2 market data inputs.

Goodwill

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the acquisition of a business.  We test goodwill for impairment annually in the fourth quarter and when events or changes in circumstances indicate that the fair value of a reporting unit with goodwill has been reduced below its carrying value.  The impairment test requires allocating goodwill and other assets and liabilities to reporting units.  The fair value of each periodreporting unit is computed after giving considerationdetermined and compared to the potential dilution from outstanding Series B units,carrying value of the reporting unit.  The fair value is calculated using the expected present value of future cash flows method. Significant assumptions used in the cash flow forecasts include future net operating margins, future volumes, discount rates and future capital requirements. If the fair value of the reporting unit is less than the carrying value, including goodwill, the excess of the book value over the fair value of goodwill is charged to net income as an impairment expense.

We utilized a combination of approaches to estimate the fair value of our assets including the discounted cash flow approach, comparable company method and the cost approach, whereby certain property and equipment was adjusted for recent purchases of similar items, economic and functional obsolescence, location, normal useful lives and capacity (if applicable). We performed our fourth quarter of 2019 and first quarter of 2020 quantitative analysis using a weighted-average cost of capital of 10.0% and 18.0%, respectively, which is based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair value hierarchy.

Property and Equipment

Property and equipment primarily consists of gathering pipelines, compressor stations and the Clearwater Facility. We evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the related carrying values of the assets may not be recoverable.  Generally, the basis for making such assessments is undiscounted future cash flow projections for the assets being assessed.  If the carrying values of the assets are deemed not recoverable, the carrying values are reduced to the estimated fair values, which are calculated using the expected present value of future cash flows method. Significant assumptions used in the cash flow forecasts include future net operating margins, future volumes, discount rates and future capital requirements.

We utilized a discounted cash flow approach to estimate the fair value of our assets. We performed our first quarter of 2020 quantitative analysis using a weighted-average cost of capital of 19.0%, which is based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair value hierarchy.

Contingent Acquisition Consideration

In connection with our September 2015 acquisition of certain water treatment assets, we agreed to pay Antero Resources (a) $125 million in cash if converted method. Duringwe delivered 176 million barrels or more of fresh water during the periodsperiod between January 1, 2017 and December 31, 2019 and (b) an additional $125 million in which AMGP incurs a net loss, dilutedcash if we deliver 219 million barrels or more of fresh water during the period between January 1, 2018 and December 31, 2020. This contingent consideration liability is valued based on Level 3 inputs related to the expected average volumes and weighted average shares outstanding are equal to basic weighted average common shares outstanding becausecost of capital and was recorded at the effecttime of all equity awards is anti-dilutive.

General and Administrative and Equity-Based Compensation Costs

General and administrative costs are charged or allocated to us based on the nature of the expenses and are allocated based on our proportionate share of Antero Resources’ gross property and equipment, capital expenditures and labor costs, as applicable. These allocations are based on estimates and assumptions that management believes are reasonable.

Equity-based compensation grants are measured at their grant date fair value and related compensation cost is recognized over the vesting period of the grant. Compensation cost for awards with graded vesting provisions is recognized on a straight-line basis over the requisite service period of each separately vesting portion of the award. Estimating the fair value of each award requires management to apply judgment.

Equity-based compensation expenses that are subject to allocation as described in “—Principal Components of our Cost Structure,” are allocated to us based on our proportionate share of Antero Resources’ labor costs. These allocations are based on estimates and assumptions that management believes are reasonable.

New Accounting Pronouncements

There were 4,777,759 sharesno new accounting pronouncements issued during the year ended December 31, 2020 that had or are expected to have a material effect on the Company’s financial reporting.

Off-Balance Sheet Arrangements

As of December 31, 2020, we did not have any off-balance sheet arrangements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risk. The term “market risk” refers to the risk of loss arising from adverse changes in commodity prices and interest rates. The disclosures are not meant to be issued upon assumed conversionprecise indicators of expected future losses, but rather indicators of reasonably possible losses. This forward-looking information provides indicators of how we view and manage our ongoing market risk exposures.

Commodity Price Risk

Our gathering and compression and water services agreements with Antero Resources provide for fixed-fee structures, and we intend to continue to pursue additional fixed-fee opportunities with Antero Resources and third parties in order to avoid direct commodity price exposure. However, to the Series B Units. The effectextent that our future contractual arrangements with Antero Resources or third parties do not provide for fixed-fee structures, we may become subject to commodity price risk. We are subject to commodity price risks to the extent that they impact Antero Resources’ development program and production and therefore our gathering, compression and water handling volumes. We cannot predict to what extent our business would be impacted by lower commodity prices and any resulting impact on Antero Resources’ operations.

Interest Rate Risk

Our primary exposure to interest rate risk results from outstanding borrowings under the Credit Facility, which has a floating interest rate. We do not currently, but may in the future, hedge the interest on portions of these awards is anti-dilutive for 2017,our borrowings under the Credit Facility from time-to-time in order to manage risks associated with floating interest rates. As of December 31, 2020, we had $614 million of borrowings and thus our diluted net income per common shareno letters of credit outstanding under the Credit Facility. A 1.0% increase in the Credit Facility interest rate would have resulted in an estimated $11 million increase in interest expense for the year ended December 31, 2020.

Credit Risk

We are dependent on Antero Resources as our primary customer, and we expect to derive substantially all of our revenues from Antero Resources for the foreseeable future. As a result, any event, whether in our area of operations or otherwise, that adversely affects Antero Resources’ production, drilling schedule, financial condition, leverage, market reputation, liquidity, results of operations or cash flows may adversely affect our revenues and operating results.

Further, we are subject to the risk of non-payment or non-performance by Antero Resources, including with respect to our gathering and compression and water handling services agreements. We cannot predict the extent to which Antero Resources’ business would be impacted if conditions in the energy industry were to continue to deteriorate, nor can we estimate the impact such conditions would have on Antero Resources’ ability to execute its drilling and development program or to perform under our agreements. Any material non-payment or non-performance by Antero Resources could adversely affect our revenues and operating results and our ability to return capital to stockholders.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this annual report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2020 at a reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.  

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for us as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. This system is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Our internal control over financial reporting includes those policies and procedures that:

(i)

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of the assets;

(ii)

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

(iii)

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable assurance and may not prevent or detect all misstatements. Further, because of changes in conditions, effectiveness of internal controls over financial reporting may vary over time.

Antero Midstream Corporation:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Antero Midstream Corporation and subsidiaries (the Company) as of December 31, 2019 and 2020, the related consolidated statements of operations and comprehensive income (loss), partners’ capital and stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2020, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We have audited the accompanying consolidated balance sheets of Antero Midstream Corporation and subsidiaries (the Company) as of December 31, 2019 and 2020, the related consolidated statements of operations and comprehensive income (loss), partners’ capital and stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2020, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, 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 Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company 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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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

F-2

Table of Contents

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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Lease classification for ongoing modifications to the gathering and compression assets

As discussed in Note 7 to the consolidated financial statements, the Company determined that the gathering and compression agreement with Antero Resources Corporation is an operating lease. The Company continues to expand its gathering and compression system to serve its customer and, as a result, the minimum volume commitments and the lease payments increase for the expanded system. The increases in volume commitments and lease payments are modifications of the agreement that require evaluation of the lease classification.

We identified the evaluation of lease classification for ongoing modifications to the gathering and compression assets as a critical audit matter. The evaluation of lease classification for these modified leases, including evaluating the economic life as a key estimate, requires significant judgment.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of an internal control over the Company’s process for identifying lease modifications and evaluating lease classification for those modifications, including the review and approval of the Company’s lease modifications and the Company’s evaluation of the lease classification. We evaluated the Company’s accounting memoranda and documentation underlying the accounting conclusions reached, including application of relevant accounting guidance in regard to the modification accounting and subsequent lease classification. We evaluated the economic life used in the Company’s determination of lease classification by comparing it to relevant industry publications. We evaluated fixed assets that are placed in service for new minimum volume commitments which would require reassessment of the lease.

Impairment of Utica fresh water assets

As discussed in Note 8 to the consolidated financial statements, the Company evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying values of the assets may not be recoverable. An impairment loss is recognized if the undiscounted future cash flow projections for the assets being assessed are less than their carrying value. If the carrying values of the assets are deemed not recoverable, the carrying values are reduced to their estimated fair values based on discounted cash flows, which includes forecasted EBITDA and discount rate assumptions. During the year ended December 31, 2020 the Company recorded an impairment related to its Utica fresh water assets of $89 million.

We identified the evaluation of the impairment of Utica fresh water assets as a critical audit matter. There was a high degree of subjectivity in evaluating the key assumptions used to determine the fair value of the Utica fresh water assets. The Company used a discounted cash flow model to determine the fair value of the Utica fresh water assets which included the key assumptions of forecasted EBITDA and the discount rate.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s process of estimating the fair value of Utica fresh water assets, including controls related to the selection of the key assumptions used to determine the fair value of the Utica fresh

F-3

Table of Contents

water assets. We evaluated the Company’s forecasted EBITDA by comparing it to the Company’s historical performance. To assess the Company’s ability to forecast, we compared the Company’s historical EBITDA forecasts to actual results. In addition, we involved valuation professionals with specialized skills and knowledge who assisted in:

evaluating the approach used to value the Utica fresh water assets
evaluating the Company’s discount rate applied in the valuation of the Utica fresh water assets by comparing the Company’s inputs to publicly available data for comparable entities
testing the estimate of the Utica fresh water assets fair value using the Company’s cash flow assumptions and discount rate and comparing the results to the Company’s fair value estimate.

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements

(1) Organization

Antero Midstream Corporation was originally formed as Antero Resources Midstream Management LLC in 2013 to become the general partner of Antero Midstream Partners LP (“Antero Midstream Partners”).  On May 4, 2017, Antero Resources Midstream Management LLC converted from a limited liability company to a limited partnership under the laws of the State of Delaware and changed its name to Antero Midstream GP LP (“AMGP”) in connection with its initial public offering.  On March 12, 2019, pursuant to the Simplification Agreement, dated as of October 9, 2018, by and among AMGP, Antero Midstream Partners and certain of their affiliates (the “Simplification Agreement”), (i) AMGP was converted from a limited partnership to a corporation under the laws of the State of Delaware and changed its name to Antero Midstream Corporation (the “Conversion”), (ii) an indirect, wholly owned subsidiary of Antero Midstream Corporation was merged with and into Antero Midstream Partners, with Antero Midstream Partners surviving the merger as an indirect, wholly owned subsidiary of Antero Midstream Corporation (the “Merger”) and (iii) Antero Midstream Corporation exchanged (the “Series B Exchange” and, together with the Conversion, the Merger and the other transactions pursuant to by the Simplification Agreement, the “Transactions”) each issued and outstanding Series B Unit (the “Series B Units”) representing a membership interest in Antero IDR Holdings LLC (“IDR Holdings”) for 176.0041 shares of its common stock, par value $0.01 per share (“AM common stock”). As a result of the Transactions, Antero Midstream Partners became and is now a wholly owned subsidiary of Antero Midstream Corporation and former shareholders of AMGP, unitholders of Antero Midstream Partners, including Antero Resources Corporation (“Antero Resources”), and holders of Series B Units became owners of AM common stock. Unless the context otherwise requires, references to the “Company” refer to (i) for the period prior to March 13, 2019, AMGP and its consolidated subsidiaries, which did not include Antero Midstream Partners and its subsidiaries, and (ii) for the period beginning on March 13, 2019, Antero Midstream Corporation and its consolidated subsidiaries, including Antero Midstream Partners and its subsidiaries, including Antero Midstream LLC, Antero Water LLC (“Antero Water”), Antero Treatment LLC and Antero Midstream Finance Corporation (“Finance Corp”).

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

Certain costs of doing business incurred and charged to the Company by Antero Resources have been reflected in the accompanying consolidated financial statements. These costs include general and administrative expenses provided to the Company by Antero Resources in exchange for:

business services, such as payroll, accounts payable and facilities management;

corporate services, such as finance and accounting, legal, human resources, investor relations and public and regulatory policy; and

employee compensation, including equity-based compensation.

Transactions between the Company and Antero Resources have been identified in the consolidated financial statements (see Note 6—Transactions with Affiliates).

(b)

Principles of Consolidation

The accompanying consolidated financial statements include (i) for the period prior to March 13, 2019, the accounts of AMGP and its consolidated subsidiaries, which did not include Antero Midstream Partners and its subsidiaries, and (ii) for the period beginning on March 13, 2019, the accounts of Antero Midstream Corporation and its consolidated subsidiaries, including Antero Midstream Partners and its subsidiaries, which were acquired in the Transactions. See Note 3—Business Combination. All significant intercompany accounts and transactions have been eliminated in the Company’s consolidated financial statements.

Prior to the Transactions on March 12, 2019, AMGP had determined that Antero Midstream Partners was a variable interest entity (“VIE”) for which AMGP was not the primary beneficiary and therefore did not consolidate. AMGP concluded that Antero Resources was the primary beneficiary of Antero Midstream Partners and Antero Resources consolidated its financial results. Antero Resources was the primary beneficiary based on its power to direct the activities that most significantly impacted Antero Midstream Partners’ economic performance and its obligations to absorb losses or receive benefits of Antero Midstream Partners that would be significant to Antero Midstream Partners. Antero Resources owned approximately 53% of the outstanding limited partner interests in Antero Midstream Partners prior to the Transactions and its officers and management group also acted as management of Antero Midstream Partners. AMGP did not own any limited partnership interests in Antero Midstream Partners and had no capital interests in Antero Midstream Partners. AMGP did not provide financial support to Antero Midstream Partners.

AMGP’s ownership of the non-economic general partner interest in Antero Midstream Partners prior to the Transactions provided AMGP with significant influence over Antero Midstream Partners, but not control over the decisions that most significantly impacted the economic performance of Antero Midstream Partners. AMGP’s indirect ownership of the IDRs of Antero Midstream Partners prior to the Transactions entitled AMGP to receive cash distributions from Antero Midstream Partners when distributions exceeded certain target amounts. AMGP’s ownership of these interests prior to the Transactions did not require AMGP to provide financial support to Antero Midstream Partners. AMGP obtained these interests upon its formation for no consideration. Therefore, AMGP had no cost basis and classified its investment in Antero Midstream Partners as a long term investment. Prior to the Transactions, AMGP’s share of Antero Midstream Partner’s earnings were a result of AMGP’s ownership of the IDRs was accounted for using the equity method of accounting. AMGP recognized distributions earned from Antero Midstream Partners as “Equity in earnings of unconsolidated affiliates” on its statement of operations in the period in which they were earned and were allocated to AMGP’s capital account. AMGP’s long-term interest in the IDRs on the balance sheet was recorded in “Investment in unconsolidated affiliates.” The ownership of the general partner interests and IDRs did not provide AMGP with any claim to the assets of Antero Midstream Partners other than the balance in its Antero Midstream Partners capital account. Income related to the IDRs was recognized as earned and increased AMGP’s capital account and equity investment. When these distributions were paid to AMGP, they reduced its capital account and its equity investment in Antero Midstream Partners.

Investments in entities for which the Company exercises significant influence, but not control, are accounted for under the equity method. The Company’s judgment regarding the level of influence over its equity investments includes considering key factors such as Antero Midstream’s ownership interest, representation on the board of directors and participation in the policy-making decisions of equity method investees. Such investments are included in Investments in unconsolidated affiliates on the Company’s consolidated balance sheets. Income from investees that are accounted for under the equity method is included in Equity in earnings of unconsolidated affiliates on the Company’s consolidated statements of operations and cash flows. When the Company records its proportionate share of net income, per common share.it increases equity income in the statements of operations and comprehensive income (loss) and the

carrying value of that investment on the Company’s balance sheet. When a distribution is received, it is recorded as a reduction to the carrying value of that investment on the balance sheet.

(3)   The Company accounts for distributions received from equity method investees under the “nature of the distribution” approach. Under this approach, distributions received from equity method investees are classified on the basis of the nature of the activity or activities of the investee that generated the distribution as either a return on investment (classified as cash inflows from operating activities) or a return of investment (classified as cash inflows from investing activities).

(c)

Revenue Recognition

The Company, through Antero Midstream Partners and its affiliates, provides gathering, compression and water handling services under fee-based contracts primarily based on throughput or at cost plus a margin. Certain of these contracts contain operating leases of the Company’s assets under GAAP. Under these arrangements, the Company receives fees for gathering, compression and water handling services. The revenue the Company earns from these arrangements is directly related to (i) in the case of natural gas gathering and compression, the volumes of metered natural gas that it gathers, compresses and delivers to natural gas compression sites or other transmission delivery points, (ii) in the case of fresh water services, the quantities of fresh water delivered to its customers for use in their well completion operations, (iii) in the case of wastewater treatment services performed by the Company prior to idling of the Clearwater Facility (as defined below) in September 2019, the quantities of wastewater treated for its customers, (iv) in the case of wastewater services provided by third parties, the third-party costs the Company incurs plus 3% or (v) in the case of flowback and produced water treatment performed by the Company, a cost of service fee based on the costs incurred by the Company. The Company recognizes revenue when it satisfies a performance obligation by delivering a service to a customer or the use of leased assets to a customer. The Company includes lease revenue within revenues by service. See Note 7—Revenue.

(d)

Use of Estimates

The preparation of the consolidated financial statements and notes in conformity with GAAP requires that management formulate estimates and assumptions that affect revenues, expenses, assets, liabilities and the disclosure of contingent liabilities. Items subject to estimates and assumptions include the useful lives of property and equipment, the valuation of assets and liabilities acquired from Antero Midstream Partners, as well as the valuation of accrued liabilities, among others. Although management believes these estimates are reasonable, actual results could differ from these estimates.

(e)

Cash and Cash Equivalents

The Company considers all liquid investments purchased with an initial maturity of three months or less to be cash equivalents. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these instruments.

(f)

Property and Equipment

Property and equipment primarily consists of gathering pipelines, compressor stations and the wastewater treatment facility and related landfill (collectively, the “Clearwater Facility”) previously used for the disposal of salt therefrom, other flowback and produced water treatment facilities; and water handling pipelines and facilities stated at historical cost less accumulated depreciation, amortization and impairment. The Company capitalizes construction-related direct labor and material costs. Maintenance and repair costs are expensed as incurred.

Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives and salvage values of assets. The depreciation of fixed assets recorded under operating lease agreements is included in depreciation expense. Uncertainties that may impact these estimates of useful lives include, among others, changes in laws and regulations relating to environmental matters, including air and water quality, restoration and abandonment requirements, economic conditions and supply and demand for the Company’s services in the areas in which it operates. When assets are placed into service, management makes estimates with respect to useful lives and salvage values that management believes are reasonable.

Amortization of landfill airspace consists of the amortization of landfill capital costs, including those that have been incurred and capitalized and estimated future costs for landfill development and construction, and the amortization of asset retirement costs arising from landfill final capping, closure and post-closure obligations. Amortization expense is recorded on a units-of-consumption

F-11

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

basis, applying cost as a rate per-cubic yard. The rate per-cubic yard is calculated by dividing each component of the amortizable basis of the landfill by the number of cubic yards needed to fill the corresponding asset’s airspace. Landfill capital costs and closure and post-closure asset retirement costs are generally incurred to support the operation of the landfill over its entire operating life and are, therefore, amortized on a per-cubic yard basis using a landfill’s total airspace capacity. Estimates of disposal capacity and future development costs are created using input from independent engineers and internal technical teams and are reviewed at least annually.

The Company evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying values of the assets may not be recoverable.  Generally, the basis for making such assessments is undiscounted future cash flow projections for the assets being assessed.  If the carrying values of the assets are deemed not recoverable, the carrying values are reduced to the estimated fair values, which are based on discounted future cash flows using assumptions as to revenues, costs and discount rates typical of third-party market participants, which is a Level 3 fair value measurement. The Company recognized an impairment with respect to the Clearwater Facility during the year ended December 31, 2019. See Note 4—Clearwater Facility Idling.The Company recognized a $90 million impairment with respect to the freshwater delivery system during the year ended December 31, 2020.

(g)

Asset Retirement Obligations

The Company’s asset retirement obligations include its obligation to close, maintain and monitor landfill cells and support facilities. After the landfill is certified closed, the Company must continue to maintain and monitor the landfill for a post-closure period, which generally extends for 30 years. The Company records the fair value of its landfill retirement obligations as a liability in the period in which the regulatory obligation to retire a specific asset is triggered. For the Company’s individual landfill cells, the required closure and post-closure obligations under the terms of its permits and its intended operation of the landfill cell are triggered and recorded when the cell is placed into service and salt is initially disposed in the landfill cell. The fair value is based on the total estimated costs to close the landfill cell and perform post-closure activities once the landfill cell has reached capacity and is no longer accepting salt. Retirement obligations are increased each year to reflect the passage of time by accreting the balance at the weighted average credit-adjusted risk-free rate that is used to calculate the recorded liability, with accretion charged to direct costs. Actual cash expenditures to perform closure and post-closure activities reduce the retirement obligation liabilities as incurred. After initial measurement, asset retirement obligations are adjusted at the end of each periodto reflect changes, if any, in the estimated future cash flows underlying the obligation. Landfill retirement assets are capitalized as the related retirement obligations are incurred, and are amortized on a units-of-consumption basis as the disposal capacity is consumed.

Asset retirement obligations are recorded for fresh water impoundments and waste water pits when an abandonment date is identified. The Company records the fair value of its freshwater impoundment and waste water pit retirement obligations as liabilities in the period in which the regulatory obligation to retire a specific asset is triggered. The fair value is based on the total reclamation costs of the assets. Retirement obligations are increased each year to reflect the passage of time by accreting the balance at the weighted average credit-adjusted risk-free rate that is used to calculate the recorded liability, with accretion charged to direct costs. Actual cash expenditures to perform remediation activities reduce the retirement obligation liabilities as incurred. After initial measurement, asset retirement obligations are adjusted at the end of each periodto reflect changes, if any, in the estimated future cash flows underlying the obligation. Fresh water impoundments and wastewater pit retirement assets are capitalized as the related retirement obligations are incurred, and are amortized on a straight-line basis until reclamation. As of December 31, 2020, the Company has $5 million of asset retirement obligations it expects to settle within the next 12 months that are recorded in Other current liabilities on the consolidated balance sheet.

The Company is under no legal obligations, neither contractually nor under the doctrine of promissory estoppel, to restore or dismantle its gathering pipelines, compressor stations, water delivery pipelines, flowback and produced water facilities and the Clearwater Facility upon abandonment. See Note 4—Clearwater Facility Idling.

(h)

Litigation and Other Contingencies

A liability is recorded for a loss contingency when its occurrence is probable and damages can be reasonably estimated based on the anticipated most likely outcome or the minimum amount within a range of possible outcomes. The Company regularly reviews contingencies to determine the adequacy of our accruals and related disclosures. The ultimate amount of losses, if any, may differ from these estimates.

F-12

Table of Contents

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

The Company accrues losses associated with environmental obligations when such losses are probable and can be reasonably estimated. Accruals for estimated environmental losses are recognized no later than at the time a remediation feasibility study or an evaluation of response options, is complete. These accruals are adjusted as additional information becomes available or as circumstances change. Future environmental expenditures are not discounted to their present value. Recoveries of environmental costs from other parties are recorded separately as assets at their undiscounted value when receipt of such recoveries is probable.

As of December 31, 2019 and 2020, the Company had not recorded any liabilities for litigation, environmental or other contingencies.

(i)

Equity-Based Compensation

The Company’s consolidated financial statements include equity-based compensation costs related to awards granted by its own plans, as in place before and after the Transactions, as well as costs allocated by Antero Resources for grants made prior to the Transactions. Costs allocated from Antero Resources are offset to additional paid in capital on the consolidated balance sheet. See Note 6—Transactions with Affiliates for additional information regarding Antero Resources’ allocation of expenses to the Company. For awards granted under its own plan, the Company recognizes compensation cost related to all equity-based awards in the financial statements based on the estimated grant date fair value. The Company is authorized to grant various types of equity-based compensation awards, including stock options, stock appreciation rights, restricted stock awards, restricted stock unit (“RSU”) awards, dividend equivalent awards and other types of awards. The grant date fair values of such awards are determined based on the type of award and may utilize market prices on the date of grant, Black-Scholes option-pricing model, Monte Carlo simulations or other acceptable valuation methodologies, as appropriate for the type of equity-based award. Compensation cost is recognized ratably over the applicable vesting or service period. Forfeitures are accounted for as they occur by reversing the expense previously recognized for awards that were forfeited during the period. See Note 12—Equity-Based Compensation.

(j)

Income Taxes

The Company recognizes deferred tax assets and liabilities for temporary differences resulting from net operating loss and charitable contribution carryforwards and the differences between the financial statement and tax basis of assets and liabilities. The effect of changes in tax laws or tax rates is recognized in income during the period such changes are enacted. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. The Company regularly reviews its tax positions in each significant taxing jurisdiction during the process of evaluating its tax provision. The Company makes adjustments to its tax provision when: (i) facts and circumstances regarding a tax position change, causing a change in management’s judgment regarding that tax position; and/or (ii) a tax position is effectively settled with a tax authority at a differing amount.

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted. The CARES Act allows corporations with net operating losses (“NOLs”) incurred in 2018, 2019 and 2020 to carry back such NOLs to each of the five years preceding the year of the NOLs, beginning with the earliest year in which there was taxable income, and claim an income tax refund in the applicable carryback years. As a result of this NOLs carryback provision in the CARES Act, the Company was able to recognize an income tax refund receivable in March 2020 of $55 million, including $11 million in income tax benefit for the current year and $44 million of previously recognized deferred income tax benefit. As of December 31, 2020, the Company had received $39 million of this refund.

(k)

Fair Value Measures

The Financial Accounting Standards Board (the “FASB”) ASC Topic 820, Fair Value Measurements and Disclosures, clarifies the definition of fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. This guidance also relates to all nonfinancial assets and liabilities that are not recognized or disclosed on a recurring basis (e.g., the initial recognition of asset retirement obligations and impairments of long-lived assets). The fair value is the price that the Company estimates would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy is used to prioritize inputs to valuation techniques used to estimate fair value. An asset or liability subject to the fair value requirements is categorized within the hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The highest priority (Level 1) is given to unadjusted quoted market prices in active markets for identical assets or liabilities, and the lowest priority (Level 3) is given

F-13

Table of Contents

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

to unobservable inputs. Level 2 inputs are data, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly.

The carrying values on the consolidated balance sheet of the Company’s cash and cash equivalents, accounts receivable—Antero Resources, accounts receivable—third party, other current assets, accounts payable—Antero Resources, accounts payable—third party, accrued liabilities and, other current liabilities approximate fair values due to their short-term maturities. The assets and liabilities of Antero Midstream Partners were recorded at fair value as of the acquisition date, March 12, 2019 (see Note 3—Business Combination). Additionally, the Company uses certain valuation techniques in performing its annual goodwill impairment test described below and in determining the fair value of property and equipment, both of which were subject to impairment write downs during the years ended December 31, 2019 and 2020.

(l)

Investments in Unconsolidated Affiliates

The Company uses the equity method to account for its investments in companies if the investment provides the Company with the ability to exercise significant influence over, but not control of, the operating and financial policies of the investee. The Company’s consolidated net income includes the Company’s proportionate share of the net income or loss of such companies. The Company’s judgment regarding the level of influence over each equity method investee includes considering key factors such as the Company’s ownership interest, representation on the board of directors and participation in policy-making decisions of the investee and material intercompany transactions. See Note 16—Investments in Unconsolidated Affiliates.

(m)

Business Combinations

The Company recognizes and measures the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date, with any remaining difference recorded as goodwill. For acquisitions, management engages an independent valuation specialist, as applicable, to assist with the determination of fair value of the assets acquired, liabilities assumed and goodwill, based on recognized business valuation methodologies.  If the initial accounting for the business combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded.  Subsequent to the acquisition, and not later than one year from the acquisition date, the Company will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the acquisition date.  An adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period of the adjustment. Acquisition-related costs are expensed as incurred in connection with each business combination. See Note 3—Business Combination.

(n)

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the acquisition of a business.  Goodwill is not amortized, but rather is tested for impairment annually in the fourth quarter and when events or changes in circumstances indicate that the fair value of a reporting unit with goodwill has been reduced below its carrying value.  The impairment test requires allocating goodwill and other assets and liabilities to reporting units.  The fair value of each reporting unit is determined and compared to the carrying value of the reporting unit.  The fair value is calculated using the expected present value of future cash flows method. Significant assumptions used in the cash flow forecasts include future net operating margins, future volumes, discount rates and future capital requirements. If the fair value of the reporting unit is less than the carrying value, including goodwill, the excess of the book value over the fair value of goodwill is charged to net income as an impairment expense.

Amortization of intangible assets with definite lives is calculated using the straight-line method, which is reflective of the benefit pattern in which the estimated economic benefit is expected to be received over the estimated useful life of the intangible asset. Intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the intangible asset may not be recoverable. If the sum of the expected undiscounted future cash flows related to the asset is less than the carrying amount of the asset, an impairment loss is recognized based on the fair value of the asset. As of March 31, 2020, the Company’s goodwill was fully impaired. See Note 4—Clearwater Facility Idling and Note 5—Goodwill and Intangibles.

Treasury Share Retirement

The Company periodically retires treasury shares acquired through share repurchases and returns those shares to the status of

authorized but unissued. When treasury shares are retired, the Company’s policy is to allocate the excess of the repurchase price over the par value of shares acquired first, to additional paid-in capital, and then to accumulated earnings. The portion allocable to additional paid-in capital is determined by applying a percentage, determined by dividing the number of shares to be retired by the number of shares outstanding, to the balance of additional paid-in capital as of retirement.

(3)  Business Combination

On March 12, 2019, AMGP and Antero Midstream Partners completed the Transactions. The Transactions have been accounted for using the acquisition method of accounting with Antero Midstream Corporation identified as the acquirer of Antero Midstream Partners.

The purchase price allocation resulted in the recognition of $575 million of goodwill in 3 reporting units within the Company’s gathering and processing segment and $340 million of goodwill in 2 reporting units within its water handling segment. Substantially all of the goodwill is expected to be deductible for tax purposes. Goodwill represented the efficiencies realized with simplifying the Company’s corporate structure to own, operate and develop midstream energy infrastructure primarily to service Antero Resources. See Note 5—Goodwill and Intangibles.

Notes to Consolidated Financial Statements (Continued)

The Company’s financial statements include $6 million of acquisition-related costs associated with the Transactions for the year ended December 31, 2019. These costs were expensed as general and administrative costs.

(4)  Clearwater Facility Idling

On September 18, 2019, the Company commenced a strategic evaluation of the Clearwater Facility at which time, such facility was idled. The Company expects the facility to be idled for the foreseeable future. Accordingly, the Company performed an impairment analysis of the facility and determined: (i) to reduce the carrying value of the facility to its estimated salvage value, which included the land associated with the Clearwater Facility; (ii) the fair value of the goodwill assigned to the wastewater treatment reporting unit was less than its carrying value resulting in an impairment charge to goodwill; and (iii) the customer relationships intangible asset was impaired. Additionally, during the year ended December 31, 2020, the Company determined that the carrying value of the landfill was no longer recoverable resulting in an impairment charge to property and equipment. The following table shows the impairment charges for the years ended December 31, 2019 and 2020 related to the Clearwater Facility, which also reflect the final purchase price allocation of the Transactions (in thousands):

The Company incurred $11 million and $15 million in facility idling costs for the care and maintenance of the Clearwater Facility during the years ended December 31, 2019 and 2020, respectively.

(5)  Goodwill and Intangibles

The Company evaluates goodwill for impairment annually during the fourth quarter and whenever events or changes in circumstances indicate it is more likely than not that the fair value of a reporting unit with goodwill is less than its carrying amount. Significant assumptions used to estimate the reporting units’ fair value include the discount rate as well as estimates of future cash flows, which are impacted primarily by commodity prices and producer customers’ development plans (which impact volumes and capital requirements).

During the third quarter of 2019, the Company incurred impairment charges to the goodwill and customer relationships intangible asset associated with the Clearwater Facility, which is in the water handling segment. See Note 4—Clearwater Facility Idling.

During the fourth quarter of 2019, the Company incurred impairment charges of $298 million to its fresh water delivery and services reporting unit, which is in the water handling segment. This was primarily due to decreased water volumes driven by decreased drilling operations by Antero Resources. There was 0 goodwill remaining in this segment after this impairment was incurred.

During the first quarter of 2020, the Company performed an interim impairment analysis of the goodwill due to changes in Antero Resources’ drilling plans as a result of the decline in commodity prices. As a result of this evaluation, the Company impaired all remaining goodwill of $575 million associated with its gathering and processing segment in the first quarter of 2020.

All customer relationships are subject to amortization and will be amortized over a weighted-average period of 21 years, which reflects the remaining economic life of the relationships as of December 31, 2020. The changes in the carrying amount of customer relationships for the years ended December 31, 2019 and 2020 were as follows (in thousands):

satisfies a performance obligation by delivering a service to a customer. The Company currently derives substantially all of its revenues from Antero Resources. The following sets forth the nature, timing of satisfaction of performance obligations and significant payment terms of the Company’s contracts with Antero Resources.

Gathering and Compression Agreement

Pursuant to the gathering and compression agreement with Antero Resources, Antero Resources has dedicated substantially all of its current and future acreage in West Virginia, Ohio and Pennsylvania to the Company for gathering and compression services except for acreage subject to third-party commitments or pre-existing dedications. The Company also has an option to gather and compress natural gas produced by Antero Resources on any additional acreage it acquires during the term of the agreement outside of West Virginia, Ohio and Pennsylvania on the same terms and conditions. In December 2019, the Company and Antero Resources agreed to extend the initial term of the gathering and compression agreement to 2038 and established a growth incentive fee program whereby low pressure gathering fees will be reduced from 2020 through 2023 to the extent Antero Resources achieves certain volumetric targets at certain points during such time. For the year ended December 31, 2020, the company provided Antero Resources $48 million in rebates. Upon completion of the initial contract term, the gathering and compression agreement will continue in effect from year to year until such time as the agreement is terminated, effective upon an anniversary of the effective date of the agreement, by either the Company or Antero Resources on or before the 180th day prior to the anniversary of such effective date.

Under the gathering and compression agreement, the Company receives a low pressure gathering fee, a high pressure gathering fee and a compression fee, in each case subject to CPI-based adjustments. In addition, the agreement stipulates that the Company receives a reimbursement for the actual cost of electricity used at its compressor stations.

The Company determined that the gathering and compression agreement is an operating lease as Antero Resources obtains substantially all of the economic benefit of the asset and has the right to direct the use of the asset. The gathering system is an identifiable asset within the gathering and compression agreement, and it consists of underground low pressure pipelines that generally connect and deliver gas from specific well pads to compressor stations to compress the gas before delivery to underground high pressure pipelines that transport the gas to a third-party pipeline or plant. The gathering system is considered a single lease due to the interrelated network of the assets. When a modification to the gathering and compression agreement occurs, the Company reassesses the classification of this lease. The Company accounts for its lease and non-lease components as a single lease component as the lease component is the predominant component. The non-lease components consist of operating, oversight and maintenance of the gathering system, which are performed on time-elapsed measures. All lease payments under the future Minimum Volume Commitments discussed below are considered to be in-substance fixed lease payments under the gathering and compression agreement.

The Company recognizes revenue when low pressure volumes are delivered to a compressor station, compression volumes are delivered to a high pressure line and high pressure volumes are delivered to a processing plant or transmission pipeline. The Company invoices the customer the month after each service is performed, and payment is due in the same month.

Water Services Agreement

The Company is party to a water services agreement with Antero Resources, whereby the Company provides certain water handling services to Antero Resources within an area of dedication in defined service areas in West Virginia and Ohio. Upon completion of the initial term in 2035, the water services agreement will continue in effect from year to year until such time as the agreement is terminated, effective upon an anniversary of the effective date of the agreement, by either the Company or Antero Resources on or before the 180thday prior to the anniversary of such effective date. Under the agreement, the Company receives a fixed fee per barrel for fresh water deliveries by pipeline directly to the well site. Additionally, the Company receives a fixed fee per barrel for fresh water delivered by truck to high-rate transfer facilities. For flowback and produced water blending services, the Company receives a cost of service fee based on the costs incurred by the Company. Antero Resources also agreed to pay the Company a fixed fee per barrel for wastewater treatment at the Clearwater Facility, which was idled in the third quarter of 2019. All such fees under the agreement are subject to annual CPI-based adjustments and additional fees based on certain costs.

Under the water services agreement, the Company may also contract with third parties to provide water services to Antero Resources. Antero Resources reimburses the Company for third-party out-of-pocket costs plus a 3% markup.

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

The Company satisfies its performance obligations and recognizes revenue when the fresh water volumes have been delivered to the hydration unit of a specified well pad, flowback and produced water blending services have been completed, or prior to the idling of the Clearwater Facility in September 2019, when the wastewater volumes were delivered to the Clearwater Facility. The Company invoices the customer the month after water services are performed, and payment is due in the same month. For services contracted through third-party providers, the Company’s performance obligation is satisfied when the service to be performed by the third-party provider has been completed. The Company invoices the customer after the third-party provider billing is received, and payment is due in the same month.

Minimum Volume Commitments

The gathering and compression agreement includes certain minimum volume commitment provisions. If and to the extent Antero Resources requests that the Company construct new high pressure lines and compressor stations, the gathering and compression agreement contains minimum volume commitments that require Antero Resources to utilize or pay for 75% of the gathering capacity and 70% of the compression capacity of such new construction for 10 years. The Company recognizes lease income from its minimum volume commitments under its gathering and compression agreement on a straight-line basis and additional operating lease income is earned when excess volumes are delivered under the contract. The Company is not party to any leases that have not commenced. Minimum volume commitments for fresh water deliveries under the water services agreement concluded at December 31, 2019.

Minimum revenue amounts under the gathering and compression minimum volume commitments as of December 31, 2020 are as follows (in thousands):

Transaction Price Allocated to Remaining Performance Obligations

The majority of the Company’s service contracts have a term greater than one year. As such, the Company is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under the Company’s service contracts, each unit of product delivered to the customer represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

The remainder of the Company’s service contracts, which relate to contracts with third parties, are short-term in nature with a contract term of one year or less. Accordingly, the Company is exempt from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

(d)

Contract Balances

Under the Company’s service contracts, the Company invoices customers after its performance obligations have been satisfied, at which point payment is unconditional. Accordingly, the Company’s service contracts do not give rise to contract assets or liabilities. As of December 31, 2020, the Company’s receivables with customers were $101 million and $74 million, respectively.

(1)Investment in Antero Midstream Partners includes $2 million of transaction costs associated with the Transactions. See Note 3—Business Combination.

As of December 31, 2019 and 2020, the Company has a deferred tax asset in its Investment in Antero Midstream Partners of $31 million and $38 million, respectively. At the time of the Transactions on March 12, 2019, the investment in Antero Midstream Partners was recorded at fair value for both GAAP and income tax purposes. The GAAP versus tax treatment of activity occurring after the transaction, such as the treatment of impairments and differing recovery rates of the underlying assets, gave rise to the deferred tax asset. Due to Antero Midstream Partners’ strong history of pre-tax earnings, the Company believes the benefits of this deferred tax asset will be realized.

In assessing the realizability of all of the deferred tax assets, management considers whether some portion or all of the deferred tax assets will be realized based on a more-likely-than-not standard of judgment. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the Company’s temporary differences become deductible. Management considers projected future taxable income and tax planning strategies in making this assessment. Based upon the projections of future taxable income over the periods in which the deferred tax assets are deductible, management believes that the Company will realize the benefits of these deductible differences and thus has not recorded a valuation allowance.

As of December 31, 2020, the Company has U.S. federal and state NOL carryforwards before the effect of income taxes of $211 million and $315 million, respectively, which have no expiration date. Tax years 2017 through 2020 remain open to examination by the U.S. Internal Revenue Service. The Company and its subsidiaries file tax returns with various state taxing authorities and those returns remain open to examination for tax years 2016 through 2020.

(a)

Antero Midstream Partners Revolving Credit Facility

Antero Midstream Partners, an indirect, wholly owned subsidiary of Antero Midstream Corporation, as borrower (the “Borrower”), has a senior secured revolving credit facility (the “Credit Facility”) with a consortium of banks. Lender commitments under the Credit Facility are currently $2.13 billion. As of December 31, 2019, the Borrower had outstanding borrowings under the Credit Facility of $960 million with a weighted average interest rate of 3.15%. As of December 31, 2020, the Borrower had outstanding borrowings under the Credit Facility of $614 million with a weighted average interest rate of 1.66%. NaN letters of credit under the Credit Facility were outstanding as of December 31, 2019 and 2020. The maturity date of the facility is October 26, 2022. The Credit Facility includes fall away covenants and lower interest rates that are triggered if and when the Borrower is assigned an Investment Grade Rating (as defined in the Credit Facility).

The Credit Facility contains certain covenants including restrictions on indebtedness, and requirements with respect to leverage and interest coverage ratios. The Credit Facility permits distributions to the holders of the Borrower’s equity interests in accordance with the cash distribution policy previously adopted by the board of directors of the general partner of the Borrower, provided that no event of default exists or would be caused thereby, and only to the extent permitted by the Borrower’s organizational documents. The Borrower was in compliance with all of the financial covenants under the Credit Facility as of December 31, 2019 and 2020.

Principal amounts borrowed are payable on the maturity date with such borrowings bearing interest that is payable quarterly or, in the case of Eurodollar Rate Loans, at the end of the applicable interest period if shorter than six months. Interest is payable at a variable rate based on LIBOR or the base rate, determined by election at the time of borrowing, plus an applicable margin rate. Interest at the time of borrowing is determined with reference to the Borrower’s then-current leverage ratio subject to certain exceptions. Commitment fees on the unused portion of the Credit Facility are due quarterly at rates ranging from 0.25% to 0.375% (subject to certain exceptions) based on the leverage ratio then in effect.

The Company’s portion of the equity-based compensation expense is included in general and administrative expenses, and recorded as a credit to the applicable classes of equity. Equity-based compensation expense allocated to Antero Midstream Partners was $4.9 million for the period from March 13, 2019 to December 31, 2019 and $5.2 million for the year ended December 31, 2020. For grants made prior to the Transactions, Antero Resources has total unamortized expense related to its various equity-based compensation plans that can be allocated to the Company of approximately $8 million as of December 31, 2020, which includes grants made under the Antero Midstream Partners Long Term Incentive Plan (the “AMP LTIP”) prior to the Transactions, which were converted into awards under the AM LTIP. A portion of this will be allocated to Antero Midstream Partners as it is amortized over the remaining service period of the related awards. The Company does not reimburse Antero Resources for noncash equity compensation allocated to it for awards issued under the AR LTIP.

Exchanged B Units

As of December 31, 2018, IDR LLCHoldings had 98,600 Series B Units authorized and outstanding that entitleentitled the holders to receive up to 6% of the amount of the distributions that Antero Midstream makesPartners made on its IDRsincentive distribution rights (“IDRs”) in excess of $7.5 million per quarter, subject to certain vesting conditions. On December 31, 2018, 65,745 Series B Units issued to common law employees of AMGP, including officers of AMGP and Antero Resources employees who provide services directly to AMGP, are classified as equity awards. Series B Units issued to Antero Resources employees who are not common law employees of AMGP are classified as liability awards. IDR LLC granted 92,000 Series B Units that are equity classified awards and 8,000 Series B Units that are liability classified awards. During the year ending December 31, 2017, 500 Series B Units that were equity classified awards were forfeited, and 900 Series B Units that were liability classified awards were forfeited. The Series B Units vest ratably over a three year period. 32,875 Series B Units vested on December 31, 2017.vested. The holders of vested Series B Units havehad the right to convert the units to common shares with a value equal to their pro rata share of up to 6% of any increase in ourAMGP’s equity value in excess of $2.0 billion. In no event will the aggregate number of newly issued common shares exceed 6%

Upon Closing of the total numberTransactions, each Series B Unit, vested and unvested, was exchanged for 176.0041 shares of our common stock (the “Series B Exchange”). A total of 17,353,999 shares of the Company’s common stock were issued and outstanding common shares.

The Company accounted for the Series B Exchange as a share-based payment modification under FASB ASC Topic 718, Stock Compensation. On March 12, 2019, which is the modification date, the Company determined the estimated fair value of the awards over the vesting period of the awards.

(c)Performance Share Unit Awards

Performance Share Unit Awards Based on Return on Invested Capital (“ROIC”)

In 2019, the Company granted performance share units (“PSUs”) to certain of its employees and executive officers, a portion of which vest based on the Company’s actual ROIC (as defined in the award agreement) over a three-year period as compared to a targeted ROIC (“ROIC PSUs”). The number of shares of common stock that may ultimately be earned with respect to the ROIC PSUs ranges from 0 to 200% of the target number of ROIC PSUs originally granted. Expense related to the ROIC PSUs is recognized based on the number of shares of common stock that are expected to be issued at the end of the measurement period, and such amountsexpense is reversed if the likelihood of achieving the performance condition decreases.

On December 17, 2019, the compensation committee of the Board modified the terms for the ROIC PSU agreement. Accordingly, the Company accounted for the amended agreement as a share-based payment modification under ASC 718, Stock Compensation and revalued the awards as of the modification date. Expense for the awards are recognized on a straight-line basis over the requisite service period of the entire award.

In 2019 and 2020, the likelihood of achieving the performance conditions related to ROIC PSU awards outstanding was probable and, therefore, for the years ended December 31, 2019 and 2020, the Company recognized expense of $0.2 million and $0.3 million, respectively.

(14)Equityand Earnings Per Common Share

(a)Preferred Stock

The Board authorized 100,000,000 shares of preferred stock in connection with the closing of the Transactions (see Note 3—Business Combination) on March 12, 2019, and issued 10,000 shares of preferred stock designated as "5.5% Series A Non-Voting Perpetual Preferred Stock" (the "Series A Preferred Stock"), to The Antero Foundation on that date. Dividends on the Series A Preferred Stock are cumulative from the date of original issue and payable in cash on the 45th day following the end of each fiscal quarter, or such other dates as the Board will approve, at a rate of 5.5% per annum on (i) the liquidation preference per share of Series A Preferred Stock (as described below) and (ii) the amount of accrued and unpaid dividends for any prior dividend period on such share of Series A Preferred Stock, if any. At any time following the date of issue, in the event of a change of control, or at any time on or after March 12, 2029, the Company may redeem the Series A Preferred Stock at a price equal to $1,000 per share, plus any accrued and unpaid dividends, payable in cash; provided that if any shares of the Series A Preferred Stock are held by The Antero Foundation at the time of such redemption, the price for redemption of each share of Series A Preferred Stock will be the greater of (i) $1,000 per share, plus any accrued but unpaid dividends, and (ii) the fair market value of the Series A Preferred Stock. On or after March 12, 2029, the holder of each share of Series A Preferred Stock (other than The Antero Foundation) may convert such shares, at any time and from time to time, at the option of the holder into a number of shares of AM common stock equal to the conversion ratio in effect on the applicable conversion date, subject to certain limitations. The Series A Preferred Stock ranks senior to the AM common stock as to dividend rights, as well as with respect to rights upon liquidation, winding-up or dissolution of the Company. Holders of the Series A Preferred Stock do not have any voting rights in the Company, except as required by law, or any preemptive rights.

The potential dilutive effects of these awards were excluded from the computation of earnings (loss) per common shares, assuming dilution because the inclusion of these awards would have been anti-dilutive.

(c)Earnings Per Common Share

Earnings per common share—basic for (i) the year ended December 31, 2018 is computed by dividing net income attributable to AMGP by the basic weighted average number of common shares representing limited partner interest in AMGP outstanding during the period and (ii) the years ended December 31, 2019 and 2020 is computed by dividing net income (loss) attributable to Antero Midstream Corporation by the basic weighted average number of shares of AM common stock outstanding during the period. Earnings per common share—assuming dilution for each period is computed after giving consideration to the potential dilution from outstanding equity awards, calculated using the treasury stock method. During periods in which the Company incurs a net loss, diluted weighted average shares outstanding are equal to basic weighted average shares outstanding because the effect of all equity awards is anti-dilutive.

At December 31, 2017,Transactions, the Company, among other things, issued shares of common stock valued at the closing market price of the common shares at the effective time of the Transactions, which was a Level 1 measurement.

The Company used the discounted cash flow approach, which is an income statement technique, to estimate the fair value of the Series B Unit awards was estimatedcustomer relationships and investments in unconsolidated affiliates using a Monte Carlo simulation using various assumptions including an equity value of $3.9 billion, expected volatility of 38% based on historical volatility of a peer group of publicly traded partnerships, a risk free rate of 2.36%, and expected IDR distributions based on internal estimates discounted based on a weighted averageweighted-average cost of capital assumption of 7.25%. Based on these assumptions, the estimated value14.1% as of each Series B Unit at December 31, 2017 was $1,787.  The fair value measurementMarch 12, 2019, which is based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair value hierarchy. The Company also used this approach in combination with the cost approach to estimate the fair value of property and equipment whereby certain property and equipment was adjusted for recent purchases of similar items, economic and functional obsolescence, location, normal useful lives and capacity (if applicable). To estimate the fair value of the long-term debt, the Company used Level 2 market data inputs.

Goodwill

We recognized expenseThe Company estimated the fair value of $34.7its assets in performing its goodwill impairment analysis. The Company utilized a combination of approaches to discounted cash flow approach, comparable company method and the market value approach. The Company used a weighted-average cost of capital of 10.0% and 18.0% as of December 31, 2019 and March 31, 2020, respectively, which were based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair value hierarchy.

Property and equipment

The Company estimated the undiscounted future cash flow projections to assess its property and equipment for impairment. The carrying values of certain fresh water permanent buried pipelines and equipment and fresh water surface pipelines and equipment were deemed not recoverable. As a result, the carrying values have been reduced to the estimated fair values, which are based on discounted future cash flows using assumptions as to revenues, costs and a discount rate typical of third-party market participants of 19.0% as of March 31, 2020, which is a Level 3 fair value measurement within the fair value hierarchy.

Contingent Acquisition Consideration

In connection with Antero Resources’ contribution of Antero Water and certain water handling assets to Antero Midstream Partners in September 2015 (the “Water Acquisition”), Antero Midstream Partners agreed to pay Antero Resources (a) $125 million in cash if Antero Midstream Partners delivered 176,295,000 barrels or more of which $30.5 million was for equity classified awards and $4.2 million was for liability classified awards,fresh water during the year endedperiod between January 1, 2017 and December 31, 2017. 2019 and (b) an additional $125 million in cash if Antero Midstream Partners delivered 219,200,000 barrels or more of fresh water during the period between January 1, 2018 and December 31, 2020. This contingent consideration liability is valued based on Level 3 inputs related to expected average volumes and weighted average cost of capital.

(16)Investments in Unconsolidated Affiliates

(a)

Summary of Investments in Unconsolidated Affiliates

Investment in Antero Midstream Partners

Prior to the closing of the Transactions, AMGP did not consolidate Antero Midstream Partners, and AMGP’s share of Antero Midstream Partners’ earnings as a result of AMGP’s ownership of the IDRs was accounted for using the equity method of accounting. AMGP recognized distributions earned from Antero Midstream Partners as “Equity in earnings of unconsolidated affiliates” on its statement of operations in the period in which they were earned and were allocated to AMGP’s capital account. AMGP’s long-term interest in the IDRs on the balance sheet was recorded in “Investment in unconsolidated affiliates.” The ownership of the general partner interests and IDRs did not provide AMGP with any claim to the assets of AMGP other than the balance in its Antero Midstream Partners capital account. Income related to the IDRs was recognized as earned and increased AMGP’s capital account and equity investment. When these distributions were paid to AMGP, they reduced its capital account and its equity investment in Antero Midstream Partners. As a result of the Transactions, Antero Midstream Corporation assumed financial control of Antero Midstream Partners and Antero Midstream Partners is now consolidated (see Note 3—Business Combination).

Investment in Stonewall and MarkWest Joint Venture

The Company has a 15% equity interest in a gathering system of Stonewall, which operates a 67-mile pipeline on which Antero Resources is an anchor shipper.

The Company has a 50% equity interest in the Joint Venture to develop processing and fractionation assets with MarkWest, a wholly owned subsidiary of MPLX, LP. The Joint Venture was formed to develop processing and fractionation assets in Appalachia. MarkWest operates the Joint Venture assets, which consist of processing plants in West Virginia and a one-third interest in 2 MarkWest fractionators in Ohio.

The Company’s net income (loss) includes its proportionate share of the net income of the Joint Venture and Stonewall. When the Company records its proportionate share of net income, it increases equity income in the consolidated statements of operations and comprehensive income and the carrying value of that investment on its balance sheet. When distributions on the

Company’s proportionate share of net income are received, they are recorded as reductions to the carrying value of the investment on the balance sheet and are classified as cash inflows from operating activities in accordance with the nature of the approach under FASB ASC Topic 230, Statement of Cash Flows. The Company uses the equity method of accounting to account for generalits investments in Stonewall and administrative expenses.the Joint Venture because it exercises significant influence, but not control, over the entities. The Company’s judgment regarding the level of influence over its equity investments includes considering key factors such as its ownership interest, representation on the applicable board of directors and participation in policy-making decisions of Stonewall and the Joint Venture.

(17)Reporting Segments

Prior to the closing of the Transactions, AMGP had 0 reporting segment results. Following the completion of the Transactions, the Company’s operations, which are located in the United States, are organized into 2 reporting segments: (i) gathering and processing and (ii) water handling.

Gathering and Processing

The gathering and processing segment includes a network of gathering pipelines and compressor stations that collect and process production from Antero Resources’ wells in West Virginia and Ohio. The gathering and processing segment also includes equity in earnings from the Company’s investments in the Joint Venture and Stonewall.

Water Handling

The Company’s water handling segment includes 2 independent systems that deliver fresh water from sources including the Ohio River, local reservoirs and several regional waterways. The water handling segment also includes the Clearwater Facility that was placed in service in 2018 and idled in September 2019 (See Note 4—Clearwater Facility Idling), as well as other fluid handling services, which includes high rate transfer, wastewater transportation, disposal and treatment. See Note 8—Property and Equipment.

These segments are monitored separately by management for performance and are consistent with internal financial reporting. These segments have been identified based on the differing products and services, regulatory environment and the expertise required for these operations. Management evaluates the performance of the Company’s business segments based on operating income. Interest expense is primarily managed and evaluated on a consolidated basis.
