All statements, other than statements of historical fact, included in this Quarterly Report on Form 10-Q, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements.

● our ability to realize the anticipated benefits of our investments in unconsolidated affiliates;

● our ability to execute our share repurchase program;

● natural gas, natural gas liquids (“NGLs”), and oil prices;

● impacts of geopolitical events, including the conflicts in Ukraine and in the Middle East, and world health events;

● our ability to complete the construction of or purchase new gathering and compression, processing, water handling or other assets on schedule, at the budgeted cost or at all, and the ability of such assets to operate as designed or at expected levels;

● competition;

● government regulations and changes in laws;

1

● our other plans, objectives, expectations and intentions contained in this Quarterly Report on Form 10-Q.

We caution investors that these forward-looking statements are subject to all of the risks and uncertainties incidental to our business, most of which are difficult to predict and many of which are beyond our control. These risks include, but are not limited to, commodity price volatility, inflation, supply chain or other disruptions, environmental risks, Antero Resources’ drilling and completion and other operating risks, regulatory changes or changes in law, the uncertainty inherent in projecting Antero Resources’ future rates of production, cash flows and access to capital, the timing of development expenditures, impacts of world health events, cybersecurity risks, the state of markets for, and availability of, verified quality carbon offsets and the other risks described or referenced under the heading “1A. Risk Factors” herein, including the risk factors set forth in our Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”), which is on file with the Securities and Exchange Commission (“SEC”).

All forward-looking statements, expressed or implied, included in this Quarterly Report on Form 10-Q are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

ANTERO MIDSTREAM CORPORATION

Notes to Unaudited Condensed Consolidated Financial Statements

(1) Organization

Antero Midstream Corporation together with its consolidated subsidiaries (the “Company” or “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. 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, 2023 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, 2023 consolidated financial statements were included in the Company’s 2023 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, 2023 and March 31, 2024, and the results of operations and cash flows for the three months ended March 31, 2023 and 2024. The Company has no items of other comprehensive income or loss; therefore, net income is equal to comprehensive income.

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 wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the Company’s unaudited condensed consolidated financial statements.

(c) Recently Issued Accounting Standards

Reportable Segments

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 is intended to improve reportable segment disclosures primarily through enhanced disclosure of reportable segment expenses. This ASU is effective for annual reporting periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2023-07 is required to be applied retrospectively to all prior periods presented in the financial statements. The Company is evaluating the impact that ASU 2023-07 will have on the financial statements and its plans for adoption, including the adoption date.

Income Taxes

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 is intended to improve income tax disclosures primarily through enhanced disclosure of income tax rate reconciliation items, and disaggregation of income (loss) from continuing operations, income tax expense (benefit) and income taxes paid, net disclosures by federal, state and foreign jurisdictions, among others. This ASU is effective for annual reporting periods beginning after December 15, 2024, although early adoption is permitted. ASU 2023-09 should be applied on a prospective basis, although retrospective application is permitted. The Company is evaluating the impact that ASU 2023-09 will have on the financial statements and its plans for adoption, including the adoption date and transition method.

(4) Transactions with Affiliates

(a) Revenues

Substantially all revenues earned in the three months ended March 31, 2023 and 2024 were earned from Antero Resources, under various agreements for gathering and compression and water handling services. Revenues earned from gathering and compression services consist of lease income.

ANTERO MIDSTREAM CORPORATION

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

(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 $4 million and $5 million during the three months ended March 31, 2023 and 2024, 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. General and administrative expense includes costs charged to the Company by Antero Resources of $8 million during each of the three months ended March 31, 2023 and 2024. 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. These expenses are charged to the Company based on the nature of the expenses and are apportioned based on a combination of the Company’s proportionate share of gross property and equipment, capital expenditures and labor costs, as applicable. The Company reimburses Antero Resources directly for all general and administrative costs charged to it.

(5) Revenue

All of the Company’s gathering and compression revenues are derived from operating lease agreements, and all of the Company’s water handling revenues are derived from service contracts with customers. The Company currently earns substantially all of its revenues from Antero Resources.

(a) Gathering and Compression

The Company’s gathering and compression service agreements with Antero Resources include: (i) the second amended and restated gathering and compression agreement dated December 8, 2019 (the “2019 gathering and compression agreement”), (ii) a gathering and compression agreement acquired with the Crestwood Equity Partners LP (NYSE: CEQP) (“Crestwood”) assets (the “Marcellus gathering and compression agreement”) and (iii) a compression agreement acquired with the EnLink Midstream LLC (NYSE: ENLC) (“EnLink”) assets (the “Utica compression agreement,” and together with the 2019 gathering and compression agreement and the Marcellus gathering and compression agreement, the “gathering and compression agreements”). The 2019 gathering and compression agreement and Marcellus gathering and compression agreement have initial terms through 2038 and 2031, respectively, and the Utica compression agreement has two dedicated areas that expire in 2024 and 2030. Upon expiration of the Marcellus gathering and compression agreement and the Utica compression agreement, the Company will continue to provide gathering and compression services under the 2019 gathering and compression agreement. Pursuant to the gathering and compression agreements, 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. The Company also has an option to gather and compress natural gas produced by Antero Resources on any additional undedicated acreage it acquires during the term of the 2019 gathering and compression agreement outside of West Virginia, Ohio and Pennsylvania on the same terms and conditions as the 2019 gathering and compression agreement. Upon completion of the initial contract term in 2038, the 2019 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 notice from either the Company or Antero Resources to the other party on or before the 180th day prior to the anniversary of such agreement.

The 2019 gathering and compression agreement included a growth incentive fee program whereby low pressure gathering fees were reduced from 2020 through 2023 to the extent Antero Resources achieved certain quarterly volumetric targets during such time. Antero Resources’ throughput gathered under the Marcellus gathering and compression agreement was not considered in low pressure gathering volume targets. For the three months ended March 31, 2023, Antero Resources earned a rebate of $12 million from the Company by achieving the first level volumetric target during the first quarter of 2023. The growth incentive fee rebate program expired on December 31, 2023.

ANTERO MIDSTREAM CORPORATION

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

Under the gathering and compression agreements, the Company receives, where applicable, a low pressure gathering fee, a high pressure gathering fee and a compression fee, substantially all of which are subject to annual Consumer Price Index (“CPI”)-based adjustments (or, in the case of the 2019 gathering and compression agreement, the option in certain cases to elect a cost of service fee when such assets are placed in-service). In addition, under the 2019 gathering and compression agreement, the Company receives a reimbursement for certain variable costs, such as electricity and operating expenses.

The Company determined that its gathering and compression agreements are operating leases as Antero Resources obtains substantially all of the economic benefit of the assets and has the right to direct the use of the assets. Each gathering and compression system is an identifiable asset, and consists of a network of assets that may include underground low pressure pipelines that 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, third-party processing plant or a Joint Venture processing plant. Each compression system is an identifiable asset, and consists of a network of assets that include compressor stations that connect to underground high pressure pipelines that transport the gas to a third-party pipeline, third-party processing plant or a Joint Venture processing plant. Each set of assets in an agreement is considered to be a single lease due to the interrelated network of the assets required to provide services under each respective agreement. When a modification to an agreement occurs, the Company reassesses the classification of the 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 systems, which are performed on time-elapsed measures.

The 2019 gathering and compression agreement and the Marcellus gathering and compression agreement include certain fixed fee provisions. If and to the extent Antero Resources requests that the Company construct new low pressure lines, high pressure lines and/or compressor stations, the 2019 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 cost of service fee that allows the Company to earn a 13% rate of return on such new construction over seven years, which election is made individually for each piece of equipment placed in service. In addition, the Marcellus gathering and compression agreement provides for a minimum volume commitment that requires Antero Resources to utilize or pay for 25% of the compression capacity for a period of 10 years from the in-service date. All lease payments under the minimum volume commitments and cost of service fees are considered to be in-substance fixed lease payments under the gathering and compression agreements.

The Company recognizes lease income from its minimum volume commitments and cost of service fees under its gathering and compression agreements on a straight-line basis. Additional variable operating lease income is earned when volumes in excess of the minimum commitments are delivered under the contract. The Company recognizes variable lease income 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, as applicable. Minimum volume commitments are aggregated such that there is a single minimum volume commitment for the respective service each year for each agreement. The Company invoices the customer the month after each service is performed, and payment is due in the same month. The Company is not party to any leases that have not commenced.

Minimum future lease cash flows to be received by the Company under the gathering and compression agreements as of March 31, 2024 are as follows (in thousands):

(b) Water Handling

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. The initial term of the water services agreement runs to 2035. 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 notice from either the Company or Antero Resources to the other party on or before the 180^th day prior to the anniversary of such agreement. Under the agreement, the Company receives a fixed fee for fresh water deliveries by pipeline directly to the well site, subject to annual CPI-based adjustments. In addition, the Company also provides other fluid handling services. These operations, along with the Company’s fresh water delivery systems, support well completion and production operations for Antero Resources. These services are provided by the Company directly or through third-parties with which the Company contracts. For these other fluid handling services provided by third-parties, Antero Resources reimburses the Company’s third-party out-of-pocket costs plus 3%. For these other fluid handling services provided by the Company, the Company charges Antero Resources a cost of service fee.

The Company satisfies its performance obligations and recognizes revenue when (i) the fresh water volumes have been delivered to the hydration unit of a specified well pad or (ii) other fluid handling 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.

Transaction Price Allocated to Remaining Performance Obligations

The Company’s water service agreement with Antero Resources has a term greater than one year. 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 this contract, 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 Company also performs water services for third-party customers and such contracts 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.

Contract Balances

Under the Company’s water service contracts, the Company invoices customers after the performance obligations have been satisfied, at which point payment is unconditional. Accordingly, the Company’s water service contracts do not give rise to contract assets or liabilities.

(a) Credit Facility

Antero Midstream Partners LP (“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 were $1.25 billion as of December 31, 2023 and March 31, 2024. The Credit Facility matures on October 26, 2026; provided that if on November 17, 2025 any of the 2026 Notes (as defined below) are outstanding, the Credit Facility will mature on such date. As of March 31, 2024, the Credit Facility had an available borrowing capacity of $1.25 billion.

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 Borrower’s organizational documents. The Borrower was in compliance with all of the financial covenants under the Credit Facility as of December 31, 2023 and March 31, 2024.

The Credit Facility provides for borrowing under either the Adjusted Term Secured Overnight Financing Rate (“SOFR”) or the Base Rate (as each term is defined in the 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) SOFR Loans at the end of the applicable interest period if three months (or shorter, if applicable), or every three months if the applicable interest period is longer than three months. Interest is payable at a variable rate based on SOFR or the Base Rate, determined by election at the time of borrowing, plus an applicable margin rate under the 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, 2023, the Borrower had outstanding borrowings under the Credit Facility of $630 million with a weighted average interest rate of 7.08%. As of March 31, 2024, the Borrower had no outstanding borrowings under the Credit Facility. No letters of credit under the Credit Facility were outstanding as of December 31, 2023 or March 31, 2024.

(c) Performance Share Unit Awards

2024 Performance Share Unit Awards

In March 2024, the Company granted performance share unit awards (“PSUs”) to certain of its executive officers that vest based on the Company’s actual return on invested capital (“ROIC”) (as defined in the award agreement) over a three-year period concluding on December 31, 2026 as compared to a targeted ROIC (“2024 ROIC PSUs”). The number of shares of the Company’s common stock that can be earned with respect to the 2024 ROIC PSUs ranges from zero to 200% of the target number of 2024 ROIC PSUs originally granted. The grant date fair value of these awards was based on the closing price of the Company’s common stock on the date of the grant, assuming target achievement of the performance condition. Expense related to the 2024 ROIC PSUs is recognized based on the number of shares of the Company’s 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. The likelihood of achieving the performance conditions related to 2024 ROIC PSU awards was probable as of March 31, 2024.
