ANTERO MIDSTREAM CORPORATION

Notes to Unaudited Condensed Consolidated Financial Statements

(1) Organization

Antero Midstream Corporation (together with its consolidated subsidiaries, “Antero Midstream,” “AM” or the “Company”) is a growth-oriented midstream company formed to own, operate and develop midstream energy infrastructure primarily to service Antero Resources Corporation (“Antero Resources”) and its production and completion activity in the Appalachian Basin’s Marcellus Shale and Utica Shale located in West Virginia and Ohio. The Company’s assets consist of gathering pipelines, compressor stations, interests in processing and fractionation plants and water handling assets. Antero Midstream provides midstream services to Antero Resources under long-term contracts. The Company’s corporate headquarters is located in Denver, Colorado.

(2) Summary of Significant Accounting Policies

(a)	Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information and should be read in the context of the Company’s December 31, 2020 consolidated financial statements and notes thereto for a more complete understanding of the Company’s operations, financial position, and accounting policies. The Company’s December 31, 2020 consolidated financial statements were included in the Company’s 2020 Annual Report on Form 10-K, which was filed with the SEC.

These unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information, and, accordingly, do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments (consisting of normal and recurring accruals) considered necessary to present fairly the Company’s financial position as of December 31, 2020 and September 30, 2021, the results of the Company’s operations for the three and nine months ended September 30, 2020 and 2021, and cash flows for the nine months ended September 30, 2020 and 2021. The Company has no items of other comprehensive income (loss); therefore, net income (loss) is equal to comprehensive income (loss).

Certain costs of doing business incurred and charged to the Company by Antero Resources have been reflected in the accompanying unaudited condensed 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 unaudited condensed consolidated financial statements (see Note 4—Transactions with Affiliates).

(b)	Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Antero Midstream Corporation and its consolidated subsidiaries. All significant intercompany accounts and transactions have been eliminated in the Company’s unaudited condensed consolidated financial statements.

(c)	Recently Adopted Accounting Standard

In December 2019, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Simplifying the Accounting for Income Taxes. This ASU removes certain exceptions to the general principles in Accounting Standard Codifications Topic 740, Income Taxes (“ASC 740”), and also simplifies portions of ASC 740 by clarifying and

ANTERO MIDSTREAM CORPORATION

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

amending existing guidance. It is effective for interim and annual reporting periods after December 15, 2020. The Company adopted this ASU on January 1, 2021, and it did not have a material impact on the Company's consolidated financial statements.

(3) Goodwill and Intangibles

During the first quarter of 2020, the Company performed an interim impairment analysis of its 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. Significant assumptions used to estimate the reporting units’ fair value included the discount rate as well as estimates of future cash flows, which were impacted primarily by commodity prices and producer customers’ development plans (which impact volumes and capital requirements).

All customer relationships are subject to amortization and are amortized over a weighted average period of 20 years, which reflects the remaining economic life of the relationships as of September 30, 2021. The changes in the carrying amount of customer relationships for the nine months ended September 30, 2021 were as follows (in thousands):


Customer relationships as of December 31, 2020	$	1,427,447

(5) Revenue

(a)	Revenue from Contracts with Customers

All of the Company’s revenues are currently derived from service contracts with customers and are recognized when the Company satisfies a performance obligation by delivering a service to a customer. The Company 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 quarterly volumetric targets during such time. For the three and nine months ended September 30, 2020, Antero Resources earned rebates of $12 million and $36 million, respectively, from the Company by achieving the first level volumetric target during the first, second and third quarters of 2020. Antero Resources did not earn any rebates from the Company for the three and nine months ended September 30, 2021 since Antero Resources did not achieve any volumetric targets during the first, second or third quarters of 2021. 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 180^th 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 annual 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 because 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 180^th day prior to the anniversary of such effective date. Under the agreement, the Company receives a fixed fee per barrel for fresh water delivered 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. 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.

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 or when flowback and produced water blending services have been completed. 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 options at the Company’s election for either (i) minimum volume commitments that require Antero Resources to utilize or pay for 75% of the high pressure gathering capacity and 70% of the compression 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. 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 revenue amounts under the gathering and compression minimum volume commitments as of September 30, 2021 are as follows (in thousands):

(1)	Revenue related to the gathering and processing segment is classified as lease income related to the gathering system.

(c)	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. At December 31, 2020 and September 30, 2021, the Company’s receivables with customers were $74 million and $85 million, respectively.

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, provided that no event of default exists or would be caused thereby, and only to the extent permitted by the Company’s organizational documents. The Borrower was in compliance with all of the financial covenants under the Credit Facility as of December 31, 2020 and September 30, 2021.

The Prior Credit Facility provides for borrowing under either a Base Rate or Eurodollar Rate Loan (as each term is defined in the Prior Credit Facility), and the New Credit Facility provides for borrowing under either Adjusted Term Secured Overnight Financing Rate (“SOFR”) or the Base Rate (as each term is defined in the New Credit Facility). Principal amounts borrowed are payable on the maturity date with such borrowings bearing interest that is payable with respect to (i) base rate loans, quarterly and (ii) Eurodollar Rate Loans or SOFR Loans at the end of the applicable interest period if three months or shorter or every three months if the applicable interest period is longer than three months. Interest is payable at a variable rate based on (i) LIBOR or the base rate, determined by election at the time of borrowing, plus an applicable margin rate under the Prior Credit Facility or (ii) SOFR or the base rate, determined by election at the time of borrowing, plus an applicable margin rate under the New Credit Facility. 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.

As of December 31, 2020, the Borrower had outstanding borrowings under the Prior Credit Facility of $614 million with a weighted average interest rate of 1.66%. As of September 30, 2021, the Borrower had outstanding borrowings under the Prior Credit Facility of $521 million with a weighted average interest rate of 1.59%.

The Company and each of the Company’s wholly owned subsidiaries (except for the Issuers) fully and unconditionally guaranteed the 2024 Notes, 2026 Notes, 2027 Notes, 2028 Notes and 2029 Notes (collectively the “Senior Notes”). In the event a guarantor is sold or disposed of (whether by merger, consolidation, the sale of a sufficient amount of its capital stock so that it no longer qualifies as a Restricted Subsidiary (as defined in the applicable indenture governing the series of Senior Notes) of the Issuer or the sale of all or substantially all of its assets) and whether or not the guarantor is the surviving entity in such transaction to a person that is not an Issuer or a Restricted Subsidiary of an Issuer, such guarantor will be released from its obligations under its guarantee if the sale or other disposition does not violate the covenants set forth in the indentures governing the applicable Senior Notes.

In addition, a guarantor will be released from its obligations under the applicable indenture and its guarantee, upon the release or discharge of the guarantee of other indebtedness under a credit facility that resulted in the creation of such guarantee, except a release or discharge by or as a result of payment under such guarantee; if the Issuers designate such subsidiary as an unrestricted subsidiary and such designation complies with the other applicable provisions of the indenture governing the applicable Senior Notes or in connection with any covenant defeasance, legal defeasance or satisfaction and discharge of the applicable Senior Notes.

During the three and nine months ended September 30, 2020 and 2021, all of the Company’s assets and operations are attributable to the Issuers and its guarantors.

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

Equity-based compensation expense allocated to the Company from Antero Resources was $1.2 million and $0.3 million for the three months ended September 30, 2020 and 2021, respectively and $4.5 million and $1.8 million for the nine months ended September 30, 2020 and 2021, respectively. For grants made prior to March 12, 2019, Antero Resources has total unamortized expense related to its various equity-based compensation plans that can be allocated to the Company of approximately $1.9 million as of September 30, 2021. A portion of this unamortized cost will be allocated to Antero Midstream 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 or the Antero Resources Corporation 2020 Long-Term Incentive Plan following March 12, 2019.

AM LTIP

The Company is authorized to grant up to 15,398,901 shares of AM common stock to employees and directors under the AM LTIP. The AM LTIP provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), dividend equivalents, other stock-based awards, cash awards and substitute awards. The terms and conditions of the awards granted are established by the compensation committee of the Board of Directors (the “Board”). As of September 30, 2021, a total of 10,041,012 shares were available for future grant under the AM LTIP. The Company recognized expense related to these awards, which does not include expense for the Company’s performance share unit (“PSU”) awards, of $2.3 million and $2.8 million for the three months ended September 30, 2020 and 2021, respectively, and $5.0 million and $7.9 million for the nine months ended September 30, 2020 and 2021, respectively.

(b)	Restricted Stock Unit Awards

A summary of the RSU awards activity during the nine months ended September 30, 2021 is as follows:


		Weighted Average
	Number	Grant Date
	of Units	Fair Value
Total AM LTIP RSUs awarded and unvested—December 31, 2020	3,314,955	$	8.09
Granted	1,791,444		8.71
Vested	(1,267,750)		9.07
Forfeited	(221,710)		7.36
Total AM LTIP RSUs awarded and unvested—September 30, 2021	3,616,939	$	8.10

As of September 30, 2021, unamortized expense of $24.1 million related to the unvested RSUs is expected to be recognized over a weighted average period of approximately 2.8 years and the Company’s proportionate share will be allocated to it as it is recognized.

(c)	Performance Share Unit Awards

Performance Share Unit Awards Based on Return on Invested Capital

The likelihood of achieving the performance conditions related to return on invested capital for the PSU awards outstanding was probable for the three and nine months ended September 30, 2020 and 2021. The Company recognized expense of $0.1 million for both the three months ended September 30, 2020 and 2021, and $0.2 million and $0.7 million for the nine months ended September 30, 2020 and 2021, respectively. As of September 30, 2021, there was $0.3 million of unamortized equity-based compensation expense related to unvested PSUs that is expected to be recognized over a weighted average period of 0.5 years.

(d)	Cash Awards

In January 2020, the Company granted cash awards of $2.2 million to certain executives under the AM LTIP that vest ratably over a period of up to three years. In July 2020, the Company granted additional cash awards of $0.7 million to certain non-executive employees under the AM LTIP that vest ratably over a period of four years. The compensation expense for these awards is recognized ratably over the applicable vesting period. As of December 31, 2020 and September 30, 2021, the Company has recorded $1.8 million and $1.0 million, respectively, in other liabilities in the condensed consolidated balance sheets related to unvested cash awards.

On October 13, 2021, the Board announced the declaration of a cash dividend on the shares of AM common stock of $0.225 per share for the quarter ended September 30, 2021. The dividend will be payable on November 10, 2021 to stockholders of record as of October 27, 2021. The Company pays dividends (i) out of surplus or (ii) if there is no surplus, out of the net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year, as provided under Delaware law.

The Board also declared a cash dividend of $138 thousand on the shares of Series A Preferred Stock of Antero Midstream to be paid on November 15, 2021 in accordance with the terms of the Series A Preferred Stock, which are discussed in Note 11—Equity and Earnings Per Common Share. As of September 30, 2021, there were dividends in the amount of $69 thousand accumulated in arrears on the Company’s Series A Preferred Stock.

(11) Equity and Earnings Per Common Share

(a)	Preferred Stock

The Board authorized 100,000,000 shares of preferred stock 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 45^th 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.

(b)	Weighted Average Shares Outstanding

The following is a reconciliation of the Company’s basic weighted average shares outstanding to diluted weighted average shares outstanding during the periods presented:


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(in thousands)	2020		2021		2020		2021
Basic weighted average number of shares outstanding		476,578		477,442		478,831		477,196
Add: Dilutive effect of RSUs		254		1,093		—		1,113
Add: Dilutive effect of PSUs		—		200		—		232
Add: Dilutive effect of Series A Preferred Stock		1,862		960		—		960
Diluted weighted average number of shares outstanding		478,694		479,695		478,831		479,501

Weighted average number of outstanding equity awards excluded from calculation of diluted earnings per common share ^(1):
RSUs		2,995		235		2,168		283
Series A Preferred Shares		—		—		1,862		—

(1)	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 each period is computed by dividing net income (loss) attributable to the Company 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.


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(in thousands, except per share amounts)	2020		2021		2020		2021

(12) Fair Value Measurement

Goodwill

The Company estimated the fair value of its assets in performing its goodwill impairment analysis in the first quarter of 2020. 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 18.0% as of March 31, 2020, 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

The Company estimated the undiscounted future cash flow projections to assess its property and equipment for impairment. The carrying values of certain freshwater 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 fresh water during the period between January 1, 2017 and December 31, 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.

In January 2020, Antero Midstream Partners paid Antero Resources $125 million and, as of December 31, 2020, no additional contingent acquisition consideration was earned.

Senior Unsecured Notes

As of December 31, 2020 and September 30, 2021, the fair value and carrying value of the Company’s Senior Notes were as follows:


					(Unaudited)
	December 31, 2020				September 30, 2021

Total	$	2,464,000		2,478,126		2,713,405		2,574,860

(1)	Fair values are based on Level 2 market data inputs.

(2)	Carrying values are presented net of unamortized debt issuance costs and debt premiums.

Other Assets and Liabilities

The carrying values of accounts receivable and accounts payable at December 31, 2020 and September 30, 2021 approximated fair value because of their short-term nature. The carrying value of the amounts under the Prior Credit Facility at December 31, 2020 and September 30, 2021 approximated fair value because the variable interest rates are reflective of current market conditions.

(13) Investments in Unconsolidated Affiliates

The Company has a 15% equity interest in a gathering system of Stonewall Gas Gathering LLC (“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 Energy Partners, L.P. (“MarkWest”), a wholly owned subsidiary of MPLX, LP (the “Joint Venture”). 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 two 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 unaudited condensed 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 condensed consolidated balance sheet and are classified as cash inflows from operating activities in accordance with the nature of the distribution approach under FASB ASC Topic 230, Statement of Cash Flows. The Company uses the equity method of accounting to account for its investments in Stonewall and 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.

The following table is a reconciliation of the Company’s investments in these unconsolidated affiliates:


					Total Investment
			MarkWest		in Unconsolidated

(14) Reportable Segments

The Company’s operations, which are located in the United States, are organized into two reportable 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 two 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, as well as other fluid handling services, which includes high rate transfer, wastewater transportation, disposal and blending. See Note 6—Property and Equipment.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes included elsewhere in this report. The information provided below supplements, but does not form part of, our unaudited condensed consolidated financial statements. This discussion contains forward-looking statements that are based on the views and beliefs of our management, as well as assumptions and estimates made by our management. Actual results could differ materially from such forward-looking statements as a result of various risk factors, including those that may not be in the control of management. For further information on items that could impact our future operating performance or financial condition, please see “Item 1A. Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.” We do not undertake any obligation to publicly update any forward-looking statements except as otherwise required by applicable law. In this section, references to “Antero Midstream,” “AM,” the “Company,” “we,” “us,” and “our” refer to Antero Midstream Corporation and its consolidated subsidiaries, unless otherwise indicated or the context otherwise requires.

Overview

We are a growth-oriented midstream energy company formed to own, operate and develop midstream energy assets to primarily service Antero Resources’ production and completion activity. We believe that our strategically located assets and our relationship with Antero Resources have allowed us to become a leading midstream energy company serving the Appalachian Basin. Our assets consist of gathering pipelines, compressor stations, and interests in processing and fractionation plants that collect and process production from Antero Resources’ wells in the Appalachian Basin in West Virginia and Ohio. Our assets also include two independent fresh water delivery systems that deliver fresh water from the Ohio River and several regional waterways. These fresh water delivery systems consist of permanent buried pipelines, surface pipelines and fresh water storage facilitates, as well as pumping stations and impoundments to transport the fresh water throughout the pipelines. These services are provided by us directly or through third-parties with which we contract. Our assets also include other flowback and produced water treatment facilities that we use to provide water treatment services to Antero Resources.

2021 Developments and Highlights

COVID-19 Pandemic

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. Governments tried to slow the spread of the virus by imposing social distancing guidelines, travel restrictions and stay-at-home orders, among other actions, which caused a significant decrease in activity in the global economy and the demand for oil, and to a lesser extent, natural gas and NGLs. As vaccines have become widely available, social distancing guidelines, travel restrictions and stay-at-home orders have eased, activity in the global economy has increased and demand for oil, natural gas and NGLs, and related commodity pricing, has improved. However, new variants of the virus could cause further commodity market volatility and resulting financial market instability, and these are variables beyond our control that may adversely impact our generation of funds from operating cash flows, distributions from unconsolidated affiliates, available borrowings under our Credit Facility (defined below in “—Capital Resources and Liquidity—Debt Agreements—Senior Secured Revolving Credit Facility ”) and our ability to access the capital markets.

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. As such, we have continued to operate throughout the pandemic 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 corporate offices, 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 operated in remote work from home arrangements through September 30, 2021, and due to the rise of COVID-19 cases as a result of new variants of the virus, our plans to return to full-time in-office arrangements during the third quarter of 2021 have been deferred in order to protect the health and safety of our employees and contract workers. 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.

Neither our nor Antero Resources’ supply chain has experienced any significant interruptions. 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, and as a result of the pandemic, Antero Resources has expanded its customer base and its condensate storage capacity within the Appalachian Basin. However, if Antero Resources or our other customers were to experience any production curtailments or shut-ins it would reduce throughput for our gathering and processing systems. In addition, if our customers

were to delay or discontinue drilling or completion activities, it would reduce the volumes of water that we handle and therefore revenues for our water distribution and handling business.

Financing Highlights

Credit Facility

On October 26, 2021, we entered into an amended and restated senior secured revolving credit facility with lender commitments of $1.25 billion, which matures on October 26, 2026; provided that if on November 17, 2025 any of the 7.875% senior unsecured notes due May 15, 2026 (the “2026 Notes”) are outstanding, the New Credit Facility will mature on such date. We elected to reduce our commitments from $2.13 billion under the Prior Credit Facility (as defined in “—Capital Resources and Liquidity—Debt Agreements—Senior Secured Revolving Credit Facility ”) to $1.25 billion to better align with our expected future liquidity needs. See Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements and “—Capital Resources and Liquidity—Debt Agreements—Credit Facility” for more information.

Issuance of Senior Notes

On June 8, 2021, we issued $750 million in aggregate principal amount of 5.375% senior notes due June 15, 2029 (the “2029 Notes”) at par. The 2029 Notes are unsecured and effectively subordinated to the Credit Facility to the extent of the value of the collateral securing the Credit Facility. The 2029 Notes are fully and unconditionally guaranteed on a joint and several senior unsecured basis by Antero Midstream Corporation, Antero Midstream Partners LP’s (“Antero Midstream Partners”) wholly owned subsidiaries (other than Antero Midstream Finance Corporation) and certain of its future restricted subsidiaries. See Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements for more information.

Redemption of Senior Notes

On June 8, 2021, we redeemed all of our outstanding 5.375% Senior Notes Due September 15, 2024 (the “2024 Notes”) at a redemption price of 102.688% of the principal amount therefore, plus accrued and unpaid interest. See Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements for more information.

Growth Incentive Fee Program With Antero Resources

On December 8, 2019, we and Antero Resources amended the existing gathering and compression agreement to establish a growth incentive fee program whereby we agreed to provide quarterly fee reductions to Antero Resources from 2020 through 2023, contingent upon Antero Resources achieving volumetric growth targets on low pressure gathering. The compression, high pressure gathering and fresh water delivery fees payable to us were unchanged. In addition, we and Antero Resources agreed to extend the primary term of such agreement by an additional four years to November 10, 2038. The following table summarizes the low pressure gathering growth incentive targets through 2023. If actual low pressure volumes are below the lowest threshold for the respective period, Antero Resources will not receive a reduction in low pressure gathering fees.


	Low Pressure Gathering	Quarterly Fee
	Volume Growth Incentive	Reduction
	Targets (MMcf/d)	(in millions)
Calendar Years 2021-2023
Threshold 1	>2,900 and <3,150	$12.0
Threshold 2	>3,150 and <3,400	$15.5
Threshold 3	>3,400	$19.0

For the three months ended September 30, 2021, Antero Resources delivered low pressure gathering volumes of 2,880 MMcf/d, and as a result, no quarterly fee reduction was earned during the period. During the nine months ended September 30, 2021, Antero Resources did not earn any fee reductions.

Results of Operations

We have two operating segments: (i) gathering and processing and (ii) water handling. The gathering and processing segment includes a network of gathering pipelines and compressor stations that collect and process production from Antero Resources’ wells in the Appalachian Basin, as well as equity in earnings from our investments in the joint venture to develop processing and fractionation

Table of Contents

assets with MarkWest Energy Partners, L.P., a wholly owned subsidiary of MPLX, LP (the “Joint Venture”) and Stonewall Gas Gathering LLC. The water handling segment includes (i) two independent systems that deliver fresh water from sources including the Ohio River, local reservoirs and several regional waterways, (ii) the wastewater treatment facility and related landfill (collectively, the “Clearwater Facility”) that was idled in September 2019 and (iii) other fluid handling services, which include high rate transfer, wastewater transportation, disposal and blending.

Revenues. Total revenues decreased by 4%, from $233 million, including amortization of customer relationships of $18 million, for the three months ended September 30, 2020, to $225 million, including amortization of customer relationships of $18 million, for the three months ended September 30, 2021. Gathering and processing revenues decreased by 1%, from $181 million for the three months ended September 30, 2020 to $180 million for the three months ended September 30, 2021. Water handling revenues decreased by 14%, from $52 million for the three months ended September 30, 2020 to $45 million for the three months ended September 30, 2021. These fluctuations primarily resulted from the following:

Gathering and Processing

●

Low pressure gathering revenue increased $7 million period over period due to $12 million in lower rebates to Antero Resources during the three months ended September 30, 2021, partially offset by decreased throughput volumes of 16 Bcf, or 171 MMcf/d. Low pressure gathering volumes decreased period over period primarily as a result of (i) natural production decline due to fewer new wells being connected to the system between periods and (ii) downtime at certain processing and fractionation facilities during the third quarter of 2021.

●

Compression revenue decreased $2 million period over period, and throughput volumes also decreased period over period by 8 Bcf, or 87 MMcf/d. The compression volumes decreased period over period primarily a result of to (i) natural production decline due to fewer new wells being connected to the system between periods and (ii) downtime at certain processing and fractionation facilities during the third quarter of 2021.

●

High pressure gathering revenue decreased $6 million period over period, and throughput volumes also decreased period over period by 18 Bcf, or 197 MMcf/d. The high pressure gathering volumes decreased period over period primarily as a result of (i) natural production decline due to fewer new wells being connected to the system between periods and (ii) downtime at certain processing and fractionation facilities during the third quarter of 2021.

Table of Contents

Water Handling

●

Fresh water delivery revenue decreased $7 million period over period, and fresh water volumes also decreased period over period by 1,867 MBbl or 20 MBbl/d primarily as a result of a decrease in the number of wells completed.

●

Other fluid handling services revenue remained consistent during the three months ended September 30, 2020 and 2021.

Direct operating expenses. Total direct operating expenses increased by 4%, from $38 million for the three months ended September 30, 2020 to $39 million for the three months ended September 30, 2021. Gathering and processing direct operating expenses remained consistent at $16 million for the three months ended September 30, 2020 and 2021 primarily due to higher ad valorem taxes between periods, offset by lower direct operating expenses due to lower throughput volumes between periods. Water handling direct operating expenses increased by 6%, from $22 million for the three months ended September 30, 2020 to $23 million for the three months ended September 30, 2021. The increase was primarily due to higher water trucking and disposal costs between periods.

Equity-based compensation expenses. Equity-based compensation expenses remained relatively consistent at $4 million and $3 million for the three months ended September 30, 2020 and 2021, respectively.

Facility idling expenses. Facility idling expenses decreased 66%, from $3 million for the three months ended September 30, 2020 to $1 million for the three months ended September 30, 2021 primarily due to reduced Clearwater Facility decommissioning costs between periods.

Depreciation expense. Total depreciation expense remained consistent at $27 million for the three months ended September 30, 2020 and 2021.

Interest expense. Interest expense increased by 29%, from $35 million for the three months ended September 30, 2020 to $45 million for the three months ended September 30, 2021 primarily due to the issuance of (i) $550 million of 2026 Notes on November 10, 2020 and (ii) $750 million of 2029 Notes on June 8, 2021, partially offset by lower borrowings under the Prior Credit Facility during the three months ended September 30, 2021 and the redemption of all $650 million of the 2024 Notes on June 8, 2021.

Equity in earnings of unconsolidated affiliates. Equity in earnings in unconsolidated affiliates remained relatively consistent at $23 million for the three months ended September 30, 2020 and $24 million for three months ended September 30, 2021 primarily due to one new Joint Venture processing plant with nameplate capacity of 200 MMcf/d being placed in service during July 2021, partially offset by the effects of the processing plant and fractionation facility downtime during the third quarter of 2021.

Provision for income tax expense. Income tax expense for the three months ended September 30, 2020 and 2021 was $35 million and $32 million, respectively, which reflects effective tax rates of 24.9% and 26.4%, respectively.

Net income. Net income decreased by 15% from $106 million for the three months ended September 30, 2020 to $89 million for the three months ended September 30, 2021 primarily due to lower water handling revenues and higher interest expense between periods.

Adjusted EBITDA. Adjusted EBITDA decreased by 4%, from $229 million for the three months ended September 30, 2020 to $219 million for the three months ended September 30, 2021. The decrease was primarily due to lower water handling revenues between periods.

(1)	The nine months ended September 30, 2021 average realized fee does not include $2.4 million of low pressure gathering fee revenues which volumes relate to prior periods.

Revenues. Total revenues decreased by 2%, from $697 million, including amortization of customer relationships of $53 million, for the nine months ended September 30, 2020, to $682 million, including amortization of customer relationships of $53 million, for the nine months ended September 30, 2021. Gathering and processing revenues increased by 8%, from $499 million for the nine months ended September 30, 2020 to $539 million for the nine months ended September 30, 2021. Water handling revenues decreased by 28%, from $198 million for the nine months ended September 30, 2020 to $143 million for the nine months ended September 30, 2021. These fluctuations primarily resulted from the following:

Gathering and Processing

●

Low pressure gathering revenue increased $42 million period over period due to $36 million in lower rebates to Antero Resources during the nine months ended September 30, 2021, and decreased throughput volumes of 1 Bcf. Low pressure gathering volumes decreased between periods primarily due to downtime at certain processing and fractionation facilities during the third quarter of 2021, partially offset by 66 additional wells connected to our system since September 30, 2020.

●

Compression revenue increased $2 million period over period due to increased throughput volumes of 16 Bcf, or 66 MMcf/d, primarily due to additional wells connected to our system since September 30, 2020, and one new compressor that came online during in the summer of 2020, partially offset by downtime at certain processing and fractionation facilities during the third quarter of 2021.

●

High pressure gathering revenue decreased $4 million period over period due to decreased throughput volumes of 12 Bcf, or 33 MMcf/d. The high pressure gathering volumes decreased period over period primarily as a result of downtime at certain processing and fractionation facilities during the third quarter of 2021, partially offset by new wells connected to our system since September 30, 2020.

Table of Contents

Water Handling

●

Fresh water delivery revenue decreased $35 million period over period due to decreased fresh water delivery volumes of 8,905 MBbl, or 32 MBbl/d, as a result of a decrease in the number of wells completed.

●

Other fluid handling services revenue decreased $20 million primarily due to a $23 million decrease in services that are billed at cost plus 3% as a result of operational efficiencies associated with our flowback and produced water blending services and cost reductions, partially offset by a $4 million increase in water blending services.

Direct operating expenses. Total direct operating expenses decreased by 8%, from $129 million for the nine months ended September 30, 2020 to $118 million for the nine months ended September 30, 2021. Gathering and processing direct operating expenses increased 16% from $44 million for the nine months ended September 30, 2020 to $50 million for the nine months ended September 30, 2021 primarily due to higher maintenance expense and ad valorem taxes between periods, as well as increased expense from one new compressor station that came online in the summer of 2020. Water handling direct operating expenses decreased by 20%, from $85 million for the nine months ended September 30, 2020 to $68 million for the nine months ended September 30, 2021. 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) increased 24%, from $29 million for the nine months ended September 30, 2020 to $37 million for nine months ended September 30, 2021 primarily due to (i) higher salary and wage expense, which includes our annual incentive program that was significantly reduced during 2020 (ii) higher costs allocated to us from Antero Resources during 2021and (iii) legal costs associated with the Clearwater Facility, partially offset by cost reduction efforts between periods.

Equity-based compensation expenses. Equity-based compensation expenses remained consistent at $10 million for the nine months ended September 30, 2020 and 2021.

Facility idling expenses. Facility idling expenses decreased 78%, from $14 million for the nine months ended September 30, 2020 to $3 million for the nine months ended September 30, 2021 primarily due to reduced Clearwater Facility decommissioning costs between periods.

Impairment of goodwill expense. Impairment of goodwill expense of $575 million for the nine months ended September 30, 2020 reflects an impairment of the goodwill that was associated with our gathering system due to declines in commodity prices and the industry environment.

Impairment of property and equipment expense. Impairment of property and equipment expense of $90 million for the nine months ended September 30, 2020 was primarily for the impairment of fresh water delivery assets in the Utica Shale region. Impairment of property and equipment expense of $2 million for the nine months ended September 30, 2021 was primarily due to a lower of cost of market adjustment for pipe inventory.

Depreciation expense. Total depreciation expense remained relatively consistent at $82 million and $81 million for the nine months ended September 30, 2020 and 2021, respectively.

Loss on asset sale. Loss on asset sale of $4 million for the nine months ended September 30, 2021 primarily relates to the sale of excess pipe inventory during the period.

Interest expense. Interest expense increased by 22%, from $107 million for the nine months ended September 30, 2020 to $131 million for the nine months ended September 30, 2021 primarily due to the issuance of (i) $550 million of 2026 Notes on November 10, 2020 and (ii) $750 million of 2029 Notes on June 8, 2021, partially offset by lower borrowings under the Prior Credit Facility during the nine months ended September 30, 2021 and the redemption of all $650 million of the 2024 Notes on June 8, 2021.

Equity in earnings of unconsolidated affiliates. Equity in earnings in unconsolidated affiliates increased by 5%, from $63 million for the nine months ended September 30, 2020 to $66 million for the nine months ended September 30, 2021 primarily attributable to an increase in the level of volume throughput at the Joint Venture between periods, including one new Joint Venture processing plant with nameplate capacity of 200 MMcf/d being placed in service during July 2021, partially offset by the effects of the processing plant and fractionation facility downtime during the third quarter of 2021.

Table of Contents

Loss on early extinguishment of debt. Loss on early extinguishment of debt for the nine months ended September 30, 2021 of $21 million relates to the redemption of all $650 million of the 2024 Notes at a premium to par of $17 million as well as the write-off of $6 million of unamortized deferred financing costs, partially offset by $2 million of unamortized premium.

Provision for income tax benefit (expense). Income tax benefit for the nine months ended September 30, 2020 was $78 million primarily due to the loss before taxes for the period coupled with an $11 million rate benefit related to the carryback of net operating losses to prior tax years. Income tax expense for the nine months ended September 30, 2021 was $89 million primarily due to income before taxes for the period which reflects an effective tax rate of 25.9%.

Net income (loss). Net loss was $199 million for the nine months ended September 30, 2020 primarily due to a $575 million impairment of goodwill for our gathering system and a $90 million impairment of our freshwater delivery assets. Net income was $253 million for the nine months ended September 30, 2021 primarily due to higher gathering and processing revenues and lower direct operating and facility idling expenses between periods, offset by lower water handling revenues, higher interest expense and higher loss on early extinguishment of debt between periods.

Adjusted EBITDA. Adjusted EBITDA increased by 3%, from $647 million for the nine months ended September 30, 2020 to $664 million for the nine months ended September 30, 2021. The increase was primarily due to increased gathering and compression revenues and decreased direct operating expenses and facility idling costs between periods, partially offset by lower water handling revenues between periods. For a discussion of the non-GAAP financial measure Adjusted EBITDA, including a reconciliation to its most directly comparable financial measure calculated and presented in accordance with GAAP, read “—Non-GAAP Financial Measures” below.

Capital Resources and Liquidity

Sources and Uses of Cash

Capital resources and liquidity are provided by operating cash flow, cash on our balance sheet and available borrowings under the Credit Facility and capital market transactions. We expect that the combination of these capital resources will be adequate to meet our working capital requirements, capital expenditures program, expected quarterly cash dividends and share repurchases under our share repurchases program for at least the next 12 months.

Our Board of Directors (the “Board”) declared a cash dividend on the shares of AM common stock of $0.225 per share for the quarter ended September 30, 2021. The dividend will be payable on November 10, 2021 to stockholders of record as of October 27, 2021. Our Board also declared a cash dividend of $138 thousand on the shares of Series A Preferred Stock, which will be paid on November 15, 2021 in accordance with their terms, which are discussed in Note 11—Equity and Earnings Per Common Share. As of September 30, 2021, there were dividends in the amount of $69 thousand accumulated in arrears on our Series A Preferred Stock.

We expect our future cash requirements relating to working capital, capital expenditures and quarterly cash dividends to our stockholders will be funded from cash flows internally generated from our operations or borrowings under the Credit Facility.

Cash Flows

The following table summarizes our cash flows for the nine months ended September 30, 2020 and 2021:


	Nine Months Ended September 30,
(in thousands)	2020		2021
Net cash provided by operating activities	$	546,889		545,490
Net cash used in investing activities		(188,006)		(157,365)
Net cash used in financing activities		(357,725)		(388,765)
Net increase (decrease) in cash and cash equivalents	$	1,158		(640)

Operating Activities. Net cash provided by operating activities was $547 million and $545 million for the nine months ended September 30, 2020 and 2021, respectively. The decrease in cash flows provided by operations for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020 was primarily the result of (i) lower water handling revenues, (ii) lower income tax refunds and (iii) increased interest expense, partially offset by (i) higher gathering and processing revenues, (ii) lower direct operating and facility idling expenses and (iii) lower cash used for working capital, excluding income tax

Table of Contents

receivable, between periods. We received income tax refunds during the nine months ended September 30, 2020 and 2021 of $39 million and $17 million, respectively, from certain net operating loss carryback provisions included in the Coronavirus Aid, Relief, and Economic Security Act that was enacted in March 2020.

Investing Activities. Net cash flows used in investing activities was $188 million and $157 million for the nine months ended September 30, 2020 and 2021, respectively. The decrease in cash flows used in investing activities was primarily due to (i) a $17 million decrease in additions to our gathering system and (ii) a $23 million decrease in investments made in unconsolidated affiliates, partially offset by a $9 million increase in additions to our water handling system between periods.

Financing Activities. Net cash used in financing activities was $358 million and $389 million for the nine months ended September 30, 2020 and 2021, respectively. The increase in cash flows used in financing activities was primarily due to the redemption of $650 million of 2024 Notes at 102.688% of par on June 8, 2021 and $93 million net repayments on the Prior Credit Facility during the nine months ended September 30, 2021, partially offset by (i) the issuance of $750 million of 2029 Notes on June 8, 2021 and (ii) reduced dividends to stockholders of $79 million between periods, and (iii) no payments for contingent acquisition consideration or repurchases of common stock during the nine months ended September 30, 2021. During the nine months ended September 30, 2020, we used $125 million for payment to Antero Resources for contingent acquisition consideration (net of $8 million reflected in the cash flows provided by operating operations related to the accretion of fair value), $25 million for repurchases of common stock and incurred net borrowings on the Prior Credit Facility of $228 million.

2021 Capital Investment

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 gross volumes expected from Antero Resources as a result of its drilling partnership that was announced during the first quarter of 2021. Our capital budgets may be adjusted as business conditions warrant, and we plan to expand our existing Appalachian Basin gathering, compression and water handling infrastructure to accommodate Antero Resources’ announced development plans.

Antero Resources announced its 2021 consolidated drilling and completion budget of $590 million, which includes plans to operate three drilling rigs and complete between 65 and 70 horizontal wells on a gross basis, substantially all of which are located on acreage dedicated to us. Antero also announced that as a result of the drilling partnership, the Company will increase its drilled wells from a range of 65 to 70 wells to 80 to 85 wells in 2021 on a gross basis. A further or extended decline in commodity prices could cause some of Antero Resources’ or third parties’ development and production projects to be uneconomic or less profitable, which could reduce gathering and water handling volumes in our current and future potential areas of operation. Those reductions in gathering and water handling volumes could reduce our revenue and cash flows and adversely affect our ability to return capital to holders of our common stock.

For the three and nine months ended September 30, 2021, our capital expenditures were approximately $81 million and $182 million, respectively, including $1 million and $2 million of capital investment in the Joint Venture, respectively.

Debt Agreements

Credit Facility

Antero Midstream Partners, as borrower (the “Borrower”), an indirect, wholly owned subsidiary of Antero Midstream Corporation, has a senior secured revolving credit facility with a consortium of banks. On October 26, 2021, we entered into an amended and restated senior secured revolving credit facility. References to the (i) “Prior Credit Facility” refers to the senior secured revolving credit facility in effect for periods before October 26, 2021, (ii) “New Credit Facility” refers to the senior secured revolving credit facility in effect on or after October 26, 2021 and (ii) “Credit Facility” refers to Prior Credit Facility and New Credit Facility collectively. The New Credit Facility provides for borrowing under either Adjusted Term Secured Overnight Financing Rate (“SOFR”) or the Base Rate (as each term is defined in the New Credit Facility).

The New Credit Facility has lender commitments of $1.25 billion and matures on October 26, 2026; provided that if on November 17, 2025 any of the 2026 Notes are outstanding, the New Credit Facility will mature on such date. As of September 30, 2021, we had $521 million of borrowings and no letters of credit outstanding under the Prior Credit Facility.

We have a choice of borrowing in SOFR Loans 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 SOFR

Table of Contents

Loans, the last day of each Interest Period (as defined below); provided that if any Interest Period for a SOFR Loan exceeds three months, interest will be payable on the respective dates that fall every three months after the beginning of such Interest Period. SORF Loans bear interest at a rate per annum equal to the rate for SOFR rate loans for one, two, three or six months (the “Interest Period”) plus an applicable margin ranging from 150 to 250 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 SOFR Rate loans plus 100 basis points, plus an applicable margin ranging from 50 to 150 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 New 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 September 30, 2021 under the Prior Credit Facility.

Please refer to Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements for more information on our Credit Facility.

Senior Notes

Please refer to Note 7—Long-Term Debt to the unaudited condensed consolidated financial statements and to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2020 Form 10-K for information on our Senior Notes.

Non-GAAP Financial Measures

We use Adjusted EBITDA as an important indicator of our performance. In our presentation of Adjusted EBITDA for the three months ended September 30, 2020 and 2021 net income (loss) and the corresponding adjustments reflect our actual results of operations.

Table of Contents

We define Adjusted EBITDA as net income before net interest expense, income tax expense, depreciation, impairment, accretion of asset retirement obligations, equity-based compensation, excluding equity in earnings of unconsolidated affiliates, amortization of customer relationships, loss on asset sale, loss on early extinguishment of debt 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.

Adjusted EBITDA is a non-GAAP financial measure. The GAAP measure most directly comparable to Adjusted EBITDA is net income. The non-GAAP financial measure of Adjusted EBITDA should not be considered as an alternative to the GAAP measure of net income. 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. 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.

The following table represents a reconciliation of our Adjusted EBITDA to the most directly comparable GAAP financial measure for the periods presented:

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with GAAP. The preparation of our unaudited condensed 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 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 financial statements. We provide expanded discussion of our more significant accounting policies, estimates and judgments in the 2020 Form 10-K. We believe these accounting policies reflect our more significant estimates and assumptions used in preparation of our financial statements.

Off-Balance Sheet Arrangements

As of September 30, 2021, we did not have any off-balance sheet arrangements.

Item 3. 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 precise 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 extent 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 our borrowings under the Credit Facility from time-to-time in order to manage risks associated with floating interest rates. At September 30, 2021, we had $521 million of borrowings and no letters of credit outstanding under the Prior Credit Facility. A 1.0% increase in the Prior Credit Facility interest rate would have resulted in an estimated $4 million increase in interest expense for the nine months ended September 30, 2021.

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 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 4. 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 Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file 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 rules and forms of the SEC. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of September 30, 2021 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 September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. 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 of Denver 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, and seeks monetary damages, including an approximate $26 million contract balance relating to an allegation that Antero Defendants improperly terminated the DBA. The Antero Defendants vigorously deny Veolia’s claims. 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 Defendants and Antero Treatment’s alternative claim for rescission against Veolia. All other claims remain part of the consolidated action. Following an order issued by the Court on June 17, 2021, the case is now set for trial beginning on January 24, 2022.
