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

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

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.

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

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 is a growth-oriented midstream company formed to own, operate and develop midstream energy infrastructure primarily to service Antero Resources and its production and completion activity in the Appalachian Basin. The Company’s assets consist of gathering pipelines, compressor stations, interests in processing and fractionation plants and water handling assets. The Company, through Antero Midstream Partners and its affiliates, provides midstream services to Antero Resources under long-term contracts.

(2)  Summary of Significant Accounting Policies

(a) Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, these 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, 2019 and 2020, and the results of the Company’s operations and its cash flows for the years ended December 31, 2018, 2019 and 2020. The Company has no items of other comprehensive income (loss); therefore, net income (loss) is equal to comprehensive income (loss).

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, 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.

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

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

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.

(o) Treasury Share Retirement

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

F-14

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

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 components of the fair value of consideration transferred are as follows (in thousands):

Fair value of shares of AM common stock issued (1)	$	4,017,881
Cash		598,709
Total fair value of consideration transferred	$	4,616,590

(1) The fair value of each share of AM common stock issued in connection with the Transactions was determined to be $12.54, the closing price of AMGP common shares on March 12, 2019.

The final purchase price allocation of the Transactions are summarized in the table below. The fair value of assets acquired and liabilities assumed at March 12, 2019 were as follows (in thousands):

Cash and cash equivalents	$	619,532
Accounts receivable–Antero Resources		142,312
Accounts receivable–third party		117
Other current assets		1,150
Property and equipment, net		3,371,427
Investments in unconsolidated affiliates		568,285
Customer relationships		1,567,000
Other assets, net		42,887
Total assets acquired		6,312,710

Accounts payable–third party		30,674
Accrued liabilities		87,021
Other current liabilities		537
Long-term debt		2,364,935
Contingent acquisition consideration		116,924
Other liabilities		8,524
Total liabilities assumed		2,611,931
Net assets acquired, excluding goodwill		3,700,779
Goodwill		915,811
Net assets acquired	$	4,616,590

All customer relationships are subject to amortization, which is recognized over a weighted-average period of 23 years for the remaining economic life of the relationship as of the acquisition date.

The purchase price allocation resulted in the recognition of $575 million of goodwill in three reporting units within the Company’s gathering and processing segment and $340 million of goodwill in two 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.

F-15

ANTERO MIDSTREAM CORPORATION

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):

	Year Ended December 31,
	2019		2020
Impairment of property and equipment	$	408,882	$	6,745
Impairment of goodwill		42,290		—
Impairment of customer relationships		11,871		—
Total impairment expense	$	463,043	$	6,745

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 no 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):

(6)  Transactions with Affiliates

(a) Revenues

Substantially all revenues earned in the years ended December 31, 2019 and 2020 were earned from Antero Resources, under various agreements for gathering and compression and water handling services. Revenues earned from gathering and processing services consists of lease income. There were no such revenues earned by AMGP for the year ended December 31, 2018.

(b) Accounts receivable–Antero Resources and Accounts payable–Antero Resources

Accounts receivable—Antero Resources represents amounts due from Antero Resources, primarily related to gathering and compression services and water handling services. Accounts payable—Antero Resources represents amounts due to Antero Resources for general and administrative and other costs.

(c) Allocation of Costs Charged by Antero Resources

The employees supporting the Company’s operations are concurrently employed by Antero Resources and the Company.  Direct operating expense includes costs charged to the Company of $6 million and $7 million during the years ended December 31, 2019 and 2020, respectively. These costs were for services provided by employees associated with the operation of the Company’s gathering lines, compressor stations and water handling assets.  There were no such charges to AMGP during the year ended December 31, 2018. For the years ended December 31, 2018, 2019 and 2020, general and administrative expenses charged to the Company by Antero Resources were $0.5 million, $33 million and $25 million, respectively. 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 (i) 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, and (ii) an annual management service fee.  The Company reimburses Antero Resources directly for all general and administrative costs charged to it. See Note 12—Equity-Based Compensation.

(7)  Revenue

(a) Revenue from Contracts with Customers

All of the Company’s revenues are derived from service contracts with customers and are recognized when the Company

F-17

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

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 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 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 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 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):

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

(2) Fair value of customer contracts acquired as part of the Transactions discussed in Note 3—Business Combination.

(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. As of December 31, 2020, the Company’s receivables with customers were $101 million and $74 million, respectively.

See Note 4—Clearwater Facility Idling to our consolidated financial statements for more information. During the first quarter of 2020, the Company evaluated its assets for impairment due to the decline in the industry environment as a result of low commodity prices. As a result of this evaluation, the Company recorded an impairment expense of $89 million, which included an $83 million impairment expense to its permanent buried pipelines and equipment and a $6 million impairment expense to its surface pipelines and equipment.

(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.

The Company’s long-term debt as of December 31, 2019 and 2020 was as follows:

(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%. No 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.

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 Holdings had 98,600 Series B Units authorized and outstanding that entitled the holders to receive up to 6% of the amount of the distributions that Antero Midstream Partners made on its incentive distribution rights (“IDRs”) in excess of $7.5 million per quarter, subject to certain vesting conditions.

A total of 17,353,999 shares of the Company’s common stock were issued in exchange for the 98,600 Series B Units then outstanding (the “Exchanged B Units”), which included 5,782,601 restricted shares of the Company’s common stock issued in exchange for the 32,855 unvested Series B Units.

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 unvested Series B Unit awards using a Monte Carlo simulation using various assumptions including a floor equity value of $2.0 billion, expected volatility of 40% based on historical volatility of a peer group of publicly traded partnerships, a risk free rate of 2.51% and expected IDR distributions based on internal estimates discounted based on a weighted average cost of capital assumption of 7.25%. Based on these assumptions, the estimated value of each Series B Unit was $1,257 when exchanged for shares of the

F-25

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

Company’s common stock. The fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement within the fair value hierarchy. The unvested Exchanged B Units retained the same vesting conditions as the Series B Units and vested on December 31, 2019. No awards were issued and outstanding as of December 31, 2019 and 2020. Expenses related to Exchanged B Units were recognized on a straight-line basis over the requisite service period of the entire award. Forfeitures were accounted for as they occur by reversing the expense previously recognized for awards that were forfeited during the period.

The Company recognized $66 million of equity-based compensation expense related to the Series B awards, including the Series B Units prior to the Closing of the Transactions and the Exchanged B Units following the Closing of the Transactions, for the year ended December 31, 2019. For the year ended December 31, 2018, the Company recognized $34 million of equity-based compensation expense related to the Series B Units.

AMGP LTIP

On April 17, 2017, Antero Midstream GP LP adopted the AMGP LTIP pursuant to which certain non-employee directors of Antero Midstream GP LP’s general partner and certain officers, employees and consultants of Antero Resources were eligible to receive awards representing equity interests in Antero Midstream GP LP. For the years ended December 31, 2018 and 2019, the Company recognized expense of $0.7 million and $0.2 million, respectively, related to these awards. Expenses related to these awards were recognized on a straight-line basis over the requisite service period of the entire award. Forfeitures were accounted for as they occur by reversing the expense previously recognized for awards that were forfeited during the period. In connection with the Transactions, the AMGP LTIP was terminated on March 12, 2019. No expense was recognized for the year ended December 31, 2020.

AM LTIP

Effective March, 12, 2019, the Board of Directors of Antero Midstream Corporation (the “Board”) adopted the AM LTIP under which awards may be granted to employees, directors and other service providers of the Company and its affiliates. The AM LTIP provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, 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. The Company is authorized to grant up to 15,398,901 shares of common stock to employees and directors under the AM LTIP. As of December 31, 2020, a total of 11,131,949 shares were available for future grant under the AM LTIP. For the years ended December 31, 2019 and 2020, the Company recognized expense of $2.7 million and $7.6 million, respectively, related to these awards. Expenses related to restricted stock units (“RSUs”) are recognized on a straight-line basis over the requisite service period of the entire award. Forfeitures are accounted for as they occur by reversing the expense previously recognized for awards that were forfeited during the period.

(b) Restricted Stock Unit Awards

As part of the Transactions, each of the unvested outstanding phantom units granted under the AMP LTIP was assumed by the Company and converted into 1.8926 RSUs under the AM LTIP representing a right to receive shares of the Company’s common stock for each converted phantom unit.

RSU awards vest subject to the satisfaction of service requirements. Expense related to each RSU award is recognized on a straight-line basis over the requisite service period of the entire award. Forfeitures are accounted for as they occur by reversing the expense previously recognized for awards that were forfeited during the period. The grant date fair values of these awards are determined based on the closing price of the Company’s common stock on the date of the grant.

Summary Information for Restricted Stock Unit Awards

A summary of the RSU awards activity during the year ended December 31, 2020 is as follows:

		Weighted
		Average		Aggregate
	Number	Grant Date		Intrinsic Value
	of Units	Fair Value		(in thousands)
Total AM LTIP RSUs awarded and unvested—December 31, 2019	1,275,990	$	14.38	$	9,685
Granted	2,592,191	$	6.32
Vested	(504,403)	$	14.31

Total AM LTIP RSUs awarded and unvested—December 31, 2020	3,314,955	$	8.09	$	25,558

Intrinsic values are based on the closing price of the Company’s common shares on the referenced dates. As of December 31, 2020, unamortized expense of $19 million related to the unvested RSUs is expected to be recognized over a weighted average period of approximately 2.4 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 (“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 zero 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 expense 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.

Summary Information for Performance Share Unit Awards

A summary of PSU activity for the year ended December 31, 2020 is as follows:

		Weighted
		Average
	Number	Grant Date
	of Units	Fair Value
Total awarded and unvested—December 31, 2019	148,306	$	6.32
Granted	—	$	—
Vested	—	$	—
Forfeited	—	$	—
Total awarded and unvested—December 31, 2020	148,306	$	6.32

As of December 31, 2020, there was $0.4 million of unamortized equity-based compensation expense related to unvested PSUs that is expected to be recognized over a weighted average period of 1.3 years.

(d) Cash Retention Awards

In January 2020, the Company granted cash awards of $2.2 million to certain executives under the AM LTIP that vest ratably

Notes to Consolidated Financial Statements (Continued)

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, the Company has accrued $1.8 million in other liabilities in the consolidated balance sheet related to cash awards.

(14)  Equity and 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 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:

	Year Ended December 31,
(in thousands)	2018		2019		2020
Basic weighted average number of shares outstanding		186,203		442,640		478,278
Add: Dilutive effect of RSUs		—		—		—
Add: Dilutive effect of Series A preferred stock		—		—		—
Diluted weighted average number of shares outstanding		186,203		442,640		478,278
Weighted average number of outstanding equity awards excluded from calculation of diluted earnings per common share (1):
RSUs		—		1,026		1,812
PSUs		—		—		148
Series B Units		1,366		—		—
Preferred shares		—		1,318		1,297

(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 (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.

(15)  Fair Value Measurement

Business Combination

As the Transactions were accounted for under the acquisition method of accounting, the Company estimated the fair value of assets acquired and liabilities assumed at March 12, 2019. See Note 3—Business Combination. 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 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 customer relationships and investments in unconsolidated affiliates using a weighted-average cost of capital of 14.1% as of March 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

The Company estimated the fair value of its 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 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.

F-30

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

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, 2019 and 2020 the fair value and carrying value of the Company’s senior unsecured notes were as follows:

	December 31, 2019				December 31, 2020
(in thousands)	Fair Value (1)		Carrying Value (2)		Fair Value (1)		Carrying Value (2)

Total	$	1,742,390	$	1,932,749	$	2,464,000	$	2,478,126

(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, 2019 and 2020 approximated fair value because of their short-term nature. The carrying value of the amounts under the Credit Facility at December 31, 2019 and 2020 approximated fair value because the variable interest rates are reflective of current market conditions.

(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 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 consolidated statements of operations and comprehensive income and the carrying value of that investment on its balance sheet. When distributions on the

F-31

ANTERO MIDSTREAM CORPORATION

Notes to Consolidated Financial Statements (Continued)

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 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:

(17)  Reporting Segments

Prior to the closing of the Transactions, AMGP had no reporting segment results. Following the completion of the Transactions, the Company’s operations, which are located in the United States, are organized into two 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 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 (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.
