**CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS**

Some of the information in this Quarterly Report on Form 10-Q may contain "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). 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. Words such as "may," "assume," "forecast," "position," "predict," "strategy," "expect," "intend," "plan," "estimate," "anticipate," "believe," "project," "budget," "potential," or "continue," and similar expressions are used to identify forward-looking statements, although not all forward-looking statements contain such identifying words. When considering these forward-looking statements, investors should keep in mind the risk factors and other cautionary statements in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2025. These forward-looking statements are based on management's current beliefs, based on currently available information, as to the outcome and timing of future events. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include:

● Antero Resources Corporation's ("Antero Resources") expected production and development plan;

● our ability to execute our business strategy;

● impacts to producer customers of insufficient storage capacity;

● our ability to obtain debt or equity financing on satisfactory terms to fund additional acquisitions, expansion projects, working capital requirements and the repayment or refinancing of indebtedness;

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

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

● our ability to execute our share repurchase and dividend programs;

● 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;

● risks associated with the successful integration and future performance of the HG Acquisition (as defined in Note 3—Transactions to the unaudited condensed consolidated financial statements);

● costs of conducting our operations;

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

● actions taken by third-party producers, operators, processors and transporters;

● competition;

● government regulations and changes in laws;

● operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control;

● expectations regarding the amount and timing of litigation awards;

● pending legal or environmental matters;

● uncertainty regarding our future operating results;

● credit markets;

● our ability to achieve our greenhouse gas reduction targets and the costs associated therewith;

[**Table of Contents**](#Toc)

● general economic conditions; and

● 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, 2025 (the "2025 Form 10-K"), which is on file with the Securities and Exchange Commission ("SEC").

Should one or more of the risks or uncertainties described or referenced in this Quarterly Report on Form 10-Q occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements.

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.

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q.

**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, centralized 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**

&nbsp;&nbsp;&nbsp;&nbsp;***(a)***  ***Basis of Presentation*** 

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC applicable to interim financial information and should be read in the context of the Company's December 31, 2025 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, 2025 consolidated financial statements were included in the Company's 2025 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, 2025 and March 31, 2026, and results of operations and cash flows for the three months ended March 31, 2025 and 2026. 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.

Transactions between the Company and Antero Resources have been identified in the unaudited condensed consolidated financial statements (see Note 5—Transactions with Affiliates).

&nbsp;&nbsp;&nbsp;&nbsp;***(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.

&nbsp;&nbsp;&nbsp;&nbsp;***(c)***  ***Restricted Cash*** 

The Company classifies restricted cash as all cash that is legally or contractually restricted as to withdrawal or usage, including amounts deposited in escrow that are restricted from use. The Company's restricted cash as of December 31, 2025 was classified as a current asset because the restriction on such cash was released on February 3, 2026 at the closing of the HG Acquisition (as defined in Note 3—Transactions).

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

&nbsp;&nbsp;&nbsp;&nbsp;***(d)***  ***Recently Issued Accounting Standard*** 

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses ("ASU 2024-03"). ASU 2024-03 is intended to improve the disclosure about certain operating expenses primarily through enhanced disclosure of cost of sales and selling, general and administrative expenses. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. ASU 2024-03 can be applied on either a prospective or a retrospective basis at the Company's election. The Company is evaluating the impact that ASU 2024-03 will have on the financial statements and its plans for adoption, including its transition method and adoption date.

**(3) Transactions**

***(a) HG Acquisition***

On December 5, 2025, Antero Midstream Partners LP ("Antero Midstream Partners"), an indirect, wholly-owned subsidiary of the Company, entered into a definitive agreement to acquire 100% of the issued and outstanding equity interests of HG Energy II Midstream Holdings, LLC ("HG Midstream") for cash consideration of $1.1 billion, subject to the terms and conditions thereof (the "HG Acquisition"). The HG Acquisition included gathering pipelines and integrated water handling assets in the core of the Marcellus Shale in West Virginia. On December 8, 2025, the Company deposited approximately $83 million into escrow to be credited towards the cash consideration payable at the closing of the HG Acquisition, which was classified as restricted cash on the Company's consolidated balance sheet as of December 31, 2025. This acquisition closed on February 3, 2026 (the "Closing Date"), with an effective date of January 1, 2026. In light of the nature and location of the assets and operations acquired in the HG Acquisition, the Company and Antero Resources agreed in principle to certain updates to, and intend to modify, their existing commercial arrangements to provide for on-pad compression with respect to certain wells and to provide certain water services. See Note 6—Revenue for additional information.

The HG Acquisition has been accounted for using the acquisition method of accounting with Antero Midstream Partners identified as the acquirer of HG Midstream. Due to the proximity of the HG Acquisition to March 31, 2026, the Company is still completing its analysis of the final purchase price allocation. The Company expects to complete the purchase price allocation during the 12-month period following the Closing Date. The table below summarizes the preliminary purchase price and estimated fair values of the assets acquired and liabilities assumed as of February 3, 2026. See Note 14—Fair Value Measurement for additional information on the fair value assumptions and hierarchy used in the HG Acquisition preliminary purchase price allocation.

Pro forma condensed consolidated results of operations and comprehensive income are not presented because the HG Acquisition was not significant to the Company's unaudited condensed consolidated financial statements.

***(b) Utica Shale Divestiture***

On December 5, 2025, certain wholly-owned subsidiaries of the Company entered into a purchase and sale agreement with two third-party buyers (collectively, the "Buyer Parties") to sell substantially all of the Company's Utica Shale midstream assets located in Ohio (the "Utica Shale Property and Equipment") for aggregate cash consideration of $400 million, before closing adjustments, subject to the terms and conditions thereof (the "Utica Shale Divestiture"). The Utica Shale Property and Equipment included 118 miles of gathering pipelines, 0.7 Bcfe/d of compression capacity, 85 miles of water pipelines and 12 water impoundments with storage capacity of approximately 2 million barrels. The Utica Shale Divestiture closed on February 23, 2026, with an effective date of July 1, 2025.

The Utica Shale Property and Equipment and its associated assets and liabilities were classified as held for sale as of December 31, 2025 on the Company's consolidated balance sheet, which relate to both the Company's gathering and processing and water handling reportable segments. The Utica Shale Divestiture does not qualify as a discontinued operation under FASB ASC Topic 205, *Presentation of Financial Statements*, as it does not represent a strategic shift that will have a major effect on the Company's operations or financial results.

The cash consideration received for the Utica Shale Divestiture, less costs to sell, of approximately $380 million was less than its carrying value of the Utica Shale Property and Equipment's net assets. Accordingly, the Company reduced the carrying value of the Utica Shale Property and Equipment to the estimated selling price less costs to sell and recorded a loss on long-lived assets of $87 million during the year ended December 31, 2025 in its statements of operations and comprehensive income. During the three months ended March 31, 2026, the Company recorded a gain on long-lived assets of $3 million to reflect the cash consideration received for the Utica Shale Divestiture, less costs to sell, upon transaction closing.

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

**(5) Transactions with Affiliates**

&nbsp;&nbsp;&nbsp;&nbsp;***(a)***  ***Revenues*** 

Substantially all revenues earned during the three months ended March 31, 2025 and 2026 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.

&nbsp;&nbsp;&nbsp;&nbsp;***(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 and cash consideration for the HG Acquisition. Accounts payable—Antero Resources represents amounts due to Antero Resources for general and administrative and other costs.

&nbsp;&nbsp;&nbsp;&nbsp;***(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 $5 million and $6 million during the three months ended March 31, 2025 and 2026, respectively. These costs were for services provided by employees associated with the operation of the Company's gathering lines, centralized compressor stations and water handling assets. General and administrative expense includes costs charged to the Company by Antero Resources of $9 million during each of the three months ended March 31, 2025 and 2026. 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.

**(6) 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 earned substantially all of its revenues from Antero Resources.

&nbsp;&nbsp;&nbsp;&nbsp;***(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, including the updates agreed to in principle as it relates to the HG Acquisition (the "2019 gathering and compression agreement"), (ii) a gathering and compression agreement acquired with the Crestwood Equity Partners LP ("Crestwood") assets (the "Marcellus gathering and compression agreement"), and (iii) a gathering and compression agreement acquired with the Summit Midstream Partners, LP (NYSE: SMLP) ("Summit") assets (the "Mountaineer gathering and compression agreement"). The Company also had a compression agreement acquired with the EnLink Midstream LLC (NYSE: ENLC) ("EnLink") assets that was divested at the closing of the Utica Shale Divestiture on February 23, 2026 (the "Utica compression agreement" and together with the 2019 gathering and compression agreement, the Marcellus gathering and compression agreement and the Mountaineer gathering and compression agreement, the "gathering and compression agreements").

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 2019 gathering and compression agreement, Marcellus gathering and compression agreement and Mountaineer gathering and compression agreement have initial terms through 2038, 2031 and 2026, respectively. Upon expiration of the Marcellus gathering and compression agreement and the Mountaineer gathering and compression agreement, the Company will continue to provide gathering and compression services under the 2019 gathering and compression agreement. 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

[**Table of Contents**](#Toc)

**ANTERO MIDSTREAM CORPORATION**

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

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<sup>th</sup> day prior to the anniversary of such agreement.

Under the gathering and compression agreements, the Company receives, where applicable, a gathering fee, a centralized compression fee and a high pressure gathering 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. In light of the nature and location of the assets and operations acquired in the HG Acquisition, the Company and Antero Resources agreed in principle to certain updates to, and intend to modify, their existing commercial arrangement to provide for on-pad compression with respect to certain wells. For on-pad compression services provided by third-party-owned equipment, Antero Resources will reimburse the Company's third-party out-of-pocket costs plus 3%. For on-pad compression services provided by Company-owned assets, the Company will charge Antero Resources a cost of service fee that allows the Company to earn a return on capital invested of 13% per annum over a period of seven years.

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 gathering pipelines, on-pad compression, centralized compression stations and/or high pressure pipelines, among other assets, that connect and deliver gas from specific well pads to a third-party pipeline, third-party processing plant or a Joint Venture processing plant. The Company has a compression system related to its EnLink assets that was an identifiable asset, and consisted of a network of assets that included centralized compressor stations that connected to underground high pressure pipelines that transported the gas to a third-party pipeline, third-party processing plant or a Joint Venture processing plant. The Company divested of this compression system in the Utica Shale Divestiture. 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, the Marcellus gathering and compression agreement and the Mountaineer gathering and compression agreement include certain fixed fee provisions. If and to the extent Antero Resources requests that the Company construct new gathering lines, centralized compressor stations and/or high pressure lines, 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 70% of the centralized compression capacity and 75% of the high pressure gathering capacity of such new construction for 10 years or (ii) a cost of service fee that allows the Company to earn a return on capital invested of 13% per annum over a period of seven years, which election is made individually for each piece of equipment placed in service. 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. The Mountaineer gathering and compression agreement provides for monthly minimum compression and gathering fees for each centralized compressor station or high pressure gathering line, respectively, for a period of 12 years commencing 90 days after such asset's in-service date. All lease payments under the minimum volume commitments, cost of service fees and minimum gathering and compression fees are considered to be in-substance fixed lease payments ("minimum lease payments") under the gathering and compression agreements. The minimum lease payments for the 2019 gathering and compression agreement and Mountaineer gathering and compression agreement end in 2035 and 2026, respectively. As of January 1, 2025, there were no minimum lease payments for the Marcellus gathering and compression agreement.

The Company recognizes lease income from its minimum lease payments 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 or fees are delivered under the contract. The Company recognizes variable lease income when (i) gathering volumes are delivered to a centralized compressor station, centralized compression volumes are delivered to a high pressure line and high pressure volumes are delivered to a processing plant or transmission pipeline, as applicable or (ii) on-pad compression volumes are delivered to a gathering line and gathering volumes are delivered to a processing plant or transmission pipeline, as applicable. Minimum volume commitments for the 2019 gathering and compression agreement are aggregated such that the agreement has a single minimum volume commitment for the respective service each year. The Mountaineer gathering and compression agreement minimum compression and gathering fees are not subject to aggregation

[**Table of Contents**](#Toc)

**ANTERO MIDSTREAM CORPORATION**

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

and are determined on a monthly basis for each centralized compressor station and gathering line, respectively, subject to such 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, 2026 are as follows (in thousands):

---

| | |
|:---|:---|
| Remainder of year ending December 31, 2026 | $199114 |

| Thereafter | 134944 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total | $959966 |

&nbsp;&nbsp;&nbsp;&nbsp;***(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. 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<sup>th</sup> 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 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 cost of service fee allows the Company to recover its share of capital expenditures to construct any new facilities required to provide other fluid handling services to Antero Resources and earn a return on capital invested of 13% per annum over a period of seven years. As of March 31, 2026, the Company had minimum future revenues for its cost of service fees of $65 million to be received and recognized by the Company under the water services agreement during 2026 through 2032 as the agreement's performance obligations are satisfied. In light of the nature and location of the assets and operations acquired in the HG Acquisition, the Company and Antero Resources agreed in principle to certain updates to, and intend to modify, their existing commercial arrangement to provide certain water services. For certain fresh water services provided by the Company related to the HG Energy II Production Holdings, LLC ("HG Production") assets acquired by Antero Resources, Antero Resources will reimburse the Company's third-party out-of-pocket costs plus 3%.

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 services 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.

[**Table of Contents**](#Toc)

**ANTERO MIDSTREAM CORPORATION**

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

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.

&nbsp;&nbsp;&nbsp;&nbsp;***(c)***  ***Disaggregation of Revenue*** 

In the following table, revenue is disaggregated by type of service and type of fee and is identified by the reportable segment to which such revenues relate. See Note 17—Reportable Segments for additional information.

&nbsp;&nbsp;&nbsp;&nbsp;***(a)***  ***Credit Facility*** 

On July 30, 2024, Antero Midstream Partners, as borrower (the "Borrower"), amended and restated its senior secured revolving credit facility with a syndicate of banks (as amended by the First Amendment thereto, dated as of December 11, 2025, the "Credit Facility"). The Credit Facility is guaranteed on a secured basis by Antero Midstream LLC, Antero Treatment LLC, Antero Water LLC and Antero Midstream Finance Corporation ("Finance Corp").

Lender commitments under the Credit Facility were $1.25 billion as of December 31, 2025 and March 31, 2026, respectively. The Credit Facility matures on July 30, 2029; provided that if on the date that is 91 days prior to the stated maturity of any outstanding senior unsecured notes of the Borrower, including the 2028 Notes (as defined below) and the 2029 Notes (as defined below), the outstanding principal amount of such notes is greater than or equal to $50 million and the sum of (A) the outstanding principal amount of loans, undrawn letters of credit, and drawn but unreimbursed amounts with respect to letters of credit, in each case, then outstanding under the Credit Facility plus (B) (1) the outstanding principal amount of such notes on such date minus (2) consolidated unrestricted cash of the Borrower exceeds 85% of the Aggregate Commitments (as defined in the Credit Facility), the Credit Facility will mature on such date. As of March 31, 2026, the Credit Facility had an available borrowing capacity of $808 million.

The Credit Facility contains negative and affirmative covenants applicable to the Borrower and its restricted subsidiaries customary for credit facilities of this type, including, among other things, limitations on: liens; indebtedness; investments; fundamental changes, such as mergers, consolidations, liquidations and dissolutions; the disposition of assets; transactions with affiliates that are not on arms'-length terms; prepayments and amendments of certain indebtedness; and swap and hedge transactions.

The Credit Facility permits distributions to the holders of the Borrower's equity interests in accordance with the cash distribution policy, adopted by the board under the partnership agreement 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 Credit Facility also requires the Borrower to maintain the following financial ratios:

● other than during an Investment Grade Period (as defined in the Credit Facility) a consolidated interest coverage ratio, which is the ratio of Antero Midstream Partners' consolidated EBITDA to its consolidated current interest charges of at least 2.5 to 1.0 at the end of each fiscal quarter;

● a consolidated total leverage ratio, which is the ratio of consolidated debt to consolidated EBITDA, of not more than 5.00 to 1.00 at the end of each fiscal quarter; provided that, at Antero Midstream Partners' election, which may be exercised only once, during a period that is not an Investment Grade Period (the "Financial Covenant Election"), the consolidated total leverage ratio shall be no more than 5.25 to 1.0; and

● after a Financial Covenant Election, a consolidated senior secured leverage ratio covenant in addition to the 5.25 to 1.0 consolidated total leverage ratio covenant, which is the ratio of consolidated senior secured debt to consolidated EBITDA, of not more than 3.75 to 1.0.

The Borrower was in compliance with all of the financial covenants under the Credit Facility as of December 31, 2025 and March 31, 2026.

The Credit Facility provides for borrowing under either the Adjusted Term Secured Overnight Financing Rate ("SOFR") plus a 0.10% credit adjustment spread and subject to a 0.00% floor 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. During any period that is not an Investment Grade Period, the interest margin is determined with reference to the Borrower's then-current consolidated total leverage ratio, which for SOFR loans range from 1.50% to 2.50%. During any period that is not an Investment Grade Period, commitment fees on the unused portion of the Credit Facility are due quarterly at rates ranging from 0.25% to 0.375%.

**ANTERO MIDSTREAM CORPORATION**

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

If the Borrower receives at least two Investment Grade Ratings (as defined in the Credit Facility), no default or event of default exists and the Borrower is in pro forma compliance with the Credit Facility's financial covenants (subject to provision of the Credit Facility), the Borrower may elect to enter into an Investment Grade Period. During an Investment Grade Period, the interest margin is determined by reference to the Company's corporate family rating, which for SOFR loans range from 1.125% to 2.000%. In addition, during an Investment Grade Period, the commitment fees on the unused portion of the Credit Facility are determined by reference to the Company's corporate family rating, which range from 0.125% to 0.300%. The Borrower was not in an Investment Grade Period during the three months ended March 31, 2026.

As of December 31, 2025, the Borrower had no outstanding borrowings under the Credit Facility. As of March 31, 2026, the Borrower had outstanding borrowings under the Credit Facility of $442 million with a weighted average interest rate of 5.27%. No letters of credit were outstanding under the Credit Facility as of December 31, 2025 and March 31, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;***(h)***  ***Senior Notes Guarantors***

In the event a guarantor is sold or disposed of (whether by merger, consolidation, the sale of a sufficient amount of its capital stock so that it no longer qualifies as a Restricted Subsidiary (as defined in the applicable indenture governing the series of Senior Notes) of the Issuer or the sale of all or substantially all of its assets) and whether or not the guarantor is the surviving entity in such transaction to a person that is not an Issuer or a Restricted Subsidiary of an Issuer, such guarantor will be

[**Table of Contents**](#Toc)

**ANTERO MIDSTREAM CORPORATION**

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

released from its obligations under its guarantee if the sale or other disposition does not violate the covenants set forth in the indentures governing the applicable Senior Notes.

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

During the three months ended March 31, 2025 and 2026, all of the Company's assets and operations are attributable to the Issuers and its guarantors.

**(10) Leases**

The Company leases certain compressors and water handling equipment. Leases with an initial term of 12 months or less are considered short-term and are not recorded on the balance sheet. Instead, the short-term leases are recognized in expense on a straight-line basis over the lease term.

Most leases include one or more options to renew, with renewal terms that can extend the lease for one month up to one year or more. Certain of the Company's lease contracts provide a renewal option that can be exercised at the Company's option, subject to agreement by the lessor. The depreciable lives of the leased assets are limited by the expected lease term, unless there is a transfer of title, purchase option or renewal the Company is reasonably certain to exercise. Certain of the Company's lease agreements include rental payments adjusted periodically for inflation.

The Company considers all contracts that have assets specified in the contract, either explicitly or implicitly, that the Company has substantially all of the capacity of the asset, and has the right to obtain substantially all of the economic benefits of that asset, without the lessor's ability to have a substantive right to substitute that asset, as leased assets. For any contract deemed to include a leased asset, that asset is capitalized on the condensed consolidated balance sheet as a right-of-use asset and a corresponding lease liability is recorded at the present value of the known future minimum payments of the contract using a discount rate on the date of commencement. The leased asset classification is determined at the date of recording as either operating or financing, depending upon certain criteria of the contract.

The discount rate used for present value calculations is the discount rate implicit in the contract. If an implicit rate is not determinable, a collateralized incremental borrowing rate is used at the date of commencement. As new leases commence or previous leases are modified, the discount rate used in the present value calculation is the current period applicable discount rate.

The Company has made an accounting policy election to adopt the practical expedient for combining lease and non-lease components on an asset class basis. This expedient allows the Company to combine non-lease components such as real estate taxes, insurance, maintenance and other operating expenses associated with the leased premises with the lease component of a lease agreement on an asset class basis when the non-lease components of the agreement cannot be easily bifurcated from the lease payment. Currently, the Company is applying this expedient to its compressor and water handling equipment agreements.

As of March 31, 2026, unamortized equity-based compensation expense of $65 million related to the unvested RSUs is expected to be recognized over a weighted average period of 2.3 years.

&nbsp;&nbsp;&nbsp;&nbsp;***(c)***  ***Performance Share Unit Awards*** 

*Performance Share Unit Awards Based on Return on Invested Capital*

In March 2023, the Company granted PSUs to certain of its employees and executive officers that vest based on the Company's actual ROIC (as defined in the award agreement) over a three-year period concluding on December 31, 2025 as compared to a targeted ROIC ("2023 ROIC PSUs"). The number of shares of the Company's common stock that can be earned with respect to the 2023 ROIC PSUs ranges from zero to 200% of the target number of 2023 ROIC PSUs originally granted. The performance condition for the 2023 ROIC PSUs was met at 200% of target as of December 31, 2025. As a result, during the first quarter of 2026, the 2023 ROIC PSUs vested and converted into approximately one million shares of the Company's common stock.

In March 2026, the Company granted PSUs to certain of its executive officers that vest based on the Company's actual ROIC (as defined in the award agreement) over a three-year period concluding on December 31, 2028 as compared to a targeted ROIC ("2026 ROIC PSUs"). The number of shares of the Company's common stock that can be earned with respect to the 2026 ROIC PSUs ranges from zero to 200% of the target number of 2026 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 2026 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 2026 ROIC PSU awards was probable as of March 31, 2026.

*Summary Information for Performance Share Unit Awards*

A summary of the PSU awards activity is as follows:

**(13) Equity and Net Income Per Common Share**

&nbsp;&nbsp;&nbsp;&nbsp;***(a)***  ***Preferred Stock*** 

The Board authorized 100,000,000 shares of preferred stock on March 12, 2019, and issued 10,000 shares of preferred stock designated as "5.5% Series A Non-Voting Perpetual Preferred Stock" (the "Series A Preferred Stock"), to The Antero Foundation on that date. Dividends on the Series A Preferred Stock are cumulative from the date of original issue and payable in cash on the 45<sup>th</sup> 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 the Company's 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 Company's 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.

There were no anti-dilutive securities outstanding during the three months ended March 31, 2025 and 2026.

&nbsp;&nbsp;&nbsp;&nbsp;***(c)***  ***Net Income Per Common Share*** 

Net income per common share—basic for each period is computed by dividing the net income or loss attributable to the Company by the basic weighted average number of common shares outstanding during the period. Net income per common share—diluted for each period is computed after giving consideration to the potential dilution from outstanding equity-based awards, calculated using the treasury stock method. During periods in which the Company incurs a net loss, diluted weighted average common shares outstanding are equal to basic weighted average common shares outstanding because the effect of all equity-based awards is anti-dilutive.

Notes to the Unaudited Condensed Consolidated Financial Statements (Continued)

&nbsp;&nbsp;&nbsp;&nbsp;***(b)***  ***Other Assets and Liabilities*** 

The carrying values on the condensed consolidated balance sheets of the Company's cash and cash equivalents, restricted cash, 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 carrying value of the amounts under the Credit Facility as of December 31, 2025 and March 31, 2026 approximated fair value because the variable interest rates are reflective of current market conditions.

&nbsp;&nbsp;&nbsp;&nbsp;***(c)***  ***HG Acquisition*** 

The HG Acquisition was accounted for under the acquisition method of accounting, and as such, the Company estimated the fair value of assets acquired and liabilities assumed as of February 3, 2026. See Note 3—Transactions.

The Company used a cost approach to estimate the fair value of property and equipment acquired based on inputs that are not observable in the market, whereby it is a Level 3 fair value measurement. The significant inputs to the property and equipment fair value include replacement cost of similar assets, adjusted for depreciation based on asset age and condition, economic and functional obsolescence, location, normal useful lives and capacity. The Company used a discounted cash flow technique, which is an income approach, to estimate the fair value of the customer relationships, whereby it is a Level 3 fair value measurement. The significant inputs to the customer relationships fair value include throughput and water handling volumes, estimated future service fees, capital expenditures, operating expenditures and a weighted-average cost of capital. The Company utilized a weighted average cost of capital for gathering and compression and water handling customer relationships of 14% and 16%, respectively, as of February 3, 2026.

**(15) Investments in Unconsolidated Affiliates**

The Company has a 50% equity interest in the joint venture to develop processing and fractionation assets with MarkWest Energy Partners, L.P. ("MarkWest"), a wholly owned subsidiary of MPLX, LP (the "Joint Venture"). The Joint Venture was formed to develop processing and fractionation assets in Appalachia. MarkWest operates the Joint Venture assets, which consist of processing plants in West Virginia and a one-third interest in two MarkWest fractionators in Ohio.

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

The Company's net income includes its proportionate share of the net income of the Joint Venture and Stonewall. When the Company records its proportionate share of net income, it increases equity income in the unaudited condensed consolidated statements of operations and comprehensive income and the carrying value of that investment on its condensed consolidated balance sheet. When distributions on the Company's proportionate share of net income are received, they are recorded as reductions to the carrying value of the investment on the unaudited condensed consolidated balance sheet and are classified as cash inflows from operating activities in accordance with the nature of the distribution approach under Financial Accounting Standards Board Accounting Standard Codification Topic 230, *Statement of Cash Flows*. The Company uses the equity method of accounting to account for its investments in the Joint Venture and Stonewall 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 the Joint Venture and Stonewall.

**(16) Contingencies**

The Company is currently involved in a consolidated lawsuit with Veolia Water Technologies, Inc. ("Veolia") relating to the Clearwater Facility.

On March 13, 2020, Antero Treatment LLC ("Antero Treatment"), a wholly owned subsidiary of the Company, filed suit against Veolia in the district court of Denver County, Colorado (the "Court"), asserting claims of fraud, breach of contract and other related claims. Antero Treatment alleges that Veolia failed to meet its contractual obligations to design and build a "turnkey" wastewater disposal facility under a Design/Build Agreement dated August 18, 2015 (the "DBA"), and that Veolia fraudulently concealed certain miscalculations and design flaws during contract negotiations and continued to conceal and fraudulently misrepresent the impact of certain design changes post-execution of the DBA. On March 13, 2020, Veolia filed a separate suit against the Company, Antero Resources, and certain of the Company's wholly owned subsidiaries (collectively, the "Antero Defendants") in Denver County, Colorado. In its lawsuit, Veolia asserted breach of contract and equitable claims against the Antero Defendants for alleged failures under the DBA. Veolia's suit was consolidated into the action filed by Antero Treatment.

Veolia and the Antero Defendants each filed partial motions to dismiss and motions for summary judgment directed at certain claims asserted by the opposing party. A bench trial on the remaining claims was held from January 24 through February 10, 2022 and concluded on February 24, 2022. At trial, Antero Treatment sought damages from Veolia of $450 million, which represents the Company's out-of-pocket costs associated with the Clearwater Facility project. In the alternative, Antero Treatment sought damages related to multiple breaches of the DBA, totaling $370 million. Also at trial, Veolia sought monetary damages of $118 million, including alleged delay and extra-contractual costs and a contract balance relating to an allegation that Antero Defendants improperly terminated the DBA.

On January 3, 2023, the Court found that Antero Treatment had prevailed on its claims for breach of contract and fraud, and awarded $242 million in damages to Antero Treatment, plus pre- and post-judgment interest and reasonable costs and attorneys' fees. The Court also found in Antero Defendants' favor on all of Veolia's affirmative claims. On January 27, 2023, the Court entered judgment in favor of Antero Treatment in the amount of $309 million in damages, which includes pre-judgment interest. On April 10, 2023, the Court issued an order identifying an error in its previously entered judgment, and on May 3, 2023, the Court entered an amended final judgment in favor of Antero Treatment in the amount of $280 million in damages, which includes pre-judgment interest through April 30, 2023. On May 26, 2023, Veolia filed a notice of appeal of the final judgment, and on June 9, 2023, Antero Treatment filed a notice of cross-appeal. Oral argument at the Colorado Court of Appeals occurred on October 15, 2024. On December 9, 2024, the District Court awarded Antero Treatment approximately $19 million in attorneys' fees and costs. On December 19, 2024, the Colorado Court of Appeals affirmed the District Court's May 3, 2023 judgment and associated damages award, and remanded the case to the District Court for purposes of calculating appellate attorneys' fees and costs owed to the Company by Veolia. On January 27, 2025, Veolia filed a notice of appeal of the District Court's December 9, 2024 award of attorneys' fees and costs, and on March 20, 2025, Veolia filed a petition for certiorari in the Colorado Supreme Court challenging the December 19, 2024 decision of the Court of Appeals. On June 26, 2025, the Colorado Court of Appeals dismissed Veolia's appeal of the December 9, 2024 award of attorneys' fees and costs with prejudice, following a stipulated motion by Veolia requesting such dismissal. On September 2, 2025, the Colorado Supreme Court granted in part and denied in part Veolia's petition for

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

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

**Overview**

We are a growth-oriented midstream energy company formed to own, operate and develop midstream energy assets. We believe that our strategically located assets and our relationship with Antero Resources have allowed us to become a leading midstream energy company serving the Appalachian Basin and present opportunities to expand our midstream services to other operators in the Appalachian Basin. Our assets consist of gathering pipelines, centralized compressor stations and interests in processing and fractionation plants that collect and process production from the Appalachian Basin in West Virginia and Ohio. Our assets also include an independent water handling system that delivers water from the Ohio River and several regional waterways. These water handling systems consist of permanent buried pipelines, surface pipelines and water storage facilities, as well as pumping stations, blending facilities and impoundments. Portions of these water handling systems are also utilized to transport flowback and produced water. These services are provided by us directly or through third-parties with which we contract.

**Acquisition and Divestiture**

*HG Acquisition*

On December 5, 2025, we entered into a definitive agreement to acquire 100% of the issued and outstanding equity interests of HG Midstream for cash consideration of $1.1 billion, subject to the terms and conditions thereof. The HG Acquisition included gathering pipelines and integrated water handling assets in the core of the Marcellus Shale in West Virginia. This acquisition closed on February 3, 2026. The Company's condensed consolidated statement of operations for the three months ended March 31, 2026 included results of operations from the assets and operations acquired in the HG Acquisition from February 3, 2026 through March 31, 2026.

The HG Acquisition was funded with net proceeds of the 2034 Notes, borrowing under the Credit Facility and restricted cash. See Note 3—Transactions to our condensed consolidated financial statements for additional information. In light of the nature and location of the assets and operations acquired in the HG Acquisition, we and Antero Resources agreed in principle to certain updates to, and intend to modify, our existing commercial arrangements with Antero Resources to provide for on-pad compression with respect to certain wells and to provide certain water services. See Note 6—Revenue to our condensed consolidated financial statements for additional information.

*Utica Shale Divestiture*

On December 5, 2025, we entered into a purchase and sale agreement with the Buyer Parties to sell substantially all of our Utica Shale Property and Equipment in Ohio, for aggregate cash consideration of $400 million, subject to the terms and conditions thereof. The Utica Shale Property and Equipment included 118 miles of gathering pipelines, 0.7 Bcfe/d of compression capacity, 85 miles of water pipelines and 12 water impoundments with storage capacity of approximately 2 million barrels. The Utica Shale Divestiture closed on February 23, 2026. The net proceeds from the Utica Shale Divestiture were used for the repayment of long-term debt. See Note 3—Transactions to our condensed consolidated financial statements for additional information.

**Financing Highlights**

***Share Repurchase Program***

Through our share repurchase program, during the three months ended March 31, 2026, we repurchased and retired approximately 1 million shares of our common stock for a total cost of $18 million. As of March 31, 2026, we have approximately $318 million of remaining capacity under our share repurchase program. The shares may be repurchased from time to time in open market transactions, through privately negotiated transactions or by other means in accordance with federal securities laws. The timing, as well as the number and value of shares repurchased under the program, will be determined by us at our discretion and will depend on a variety of factors, including the market price of our common stock, general market and economic conditions and applicable legal requirements. The exact number of shares to be repurchased by us is not guaranteed and the program may be suspended, modified or discontinued at any time without prior notice.

**Market Conditions and Business Trends**

***Commodity Markets***

Benchmark prices for natural gas increased significantly, while benchmark prices for oil remained relatively consistent and benchmark prices for C3+ NGLs and ethane decreased during the three months ended March 31, 2026 as compared to the same periods of 2025. While substantially all of our revenues are based on fixed-fee contracts that are not directly impacted by changes in commodity prices, commodity price changes do impact the revenues and cash flows of Antero Resources, and Antero Resources' drilling and development plan does have a direct impact on our gathering, compression and water handling services, revenues and cash flows. In the current economic environment, we expect that commodity prices for some or all of the commodities produced by Antero Resources could remain volatile. However, due to Antero Resources' increased scale, liquidity and leverage position as compared to historical levels together with Antero Resources' increased commodity derivative portfolio, we do not expect to experience significant variability in our throughput volumes resulting from volatile commodity prices.

***Economic Indicators***

The economy experienced elevated inflation levels as a result of global supply and demand imbalances, where global demand outpaced supplies beginning in 2021 and continuing through 2026. During the second half of 2024, inflation rates began to approach the Federal Reserve's stated goal of 2%, and the Federal Reserve decreased the federal funds rate by 1.75% in 2024 and 2025. Annual inflation rates have remained generally consistent at approximately 3% since 2023.

The economy also continues to be impacted by global events. These events have often caused global supply chain disruptions with additional pressure due to trade sanctions, tariffs, other global trade restrictions and conflicts, including those in the Middle East and Venezuela, among others. While neither our nor Antero Resources' supply chain has experienced any significant interruptions due to such events, there can be no assurance that we will not experience interruptions in the future.

Inflationary pressures and supply chain disruptions could result in further increases to our operating and capital costs that are not fixed. However, our gathering and compression and water agreements provide for annual CPI-based adjustments that mitigate a portion of such inflationary pressures.

These economic variables are beyond our control and may adversely impact our business, financial condition, results of operations and future cash flows.

**Results of Operations**

We have two reportable segments: (i) gathering and processing and (ii) water handling. The gathering and processing segment includes a network of gathering pipelines and centralized compressor stations and on-pad compressors that collect and process production from Antero Resources' wells in the Appalachian Basin, as well as equity in earnings from our investments in the Joint Venture and Stonewall. The Joint Venture and Stonewall provide processing and fractionation services and high-pressure gas gathering services, respectively, in the Appalachian Basin. The water handling segment includes (i) an independent system that delivers water from sources including the Ohio River, local reservoirs and several regional waterways, and (ii) other fluid handling services, which include high rate transfer, wastewater transportation, disposal and blending. See Note 17—Reportable Segments to our unaudited condensed consolidated financial statements for additional information.

\* Not meaningful or applicable.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Fresh water delivery includes fresh water charged at a fixed fee under our water services agreement with Antero Resources.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Other water handling includes fresh water charged at cost plus 3% for services provided to Antero Resources on its acreage acquired from HG Production and our other fluid handling services charged at cost plus 3% or cost of service.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The average realized fees for the three months ended March 31, 2026 include annual CPI-based adjustments of approximately 1.5%.

*Revenues.* Total revenues increased by 8%, from $291 million for the three months ended March 31, 2025 to $314 million for the three months ended March 31, 2026. Total revenues included amortization of customer relationships of $18 million and $21 million for the three months ended March 31, 2025 and 2026, respectively. Gathering and processing revenues increased by 9%, from $229 million for the three months ended March 31, 2025 to $250 million for the three months ended March 31, 2026. Water handling revenues increased by 3%, from $62 million for the three months ended March 31, 2025 to $64 million for the three months ended March 31, 2026. These fluctuations primarily resulted from the following:

*Gathering and Processing*

● Gathering revenue increased $17 million period over period primarily due to increased throughput volumes of 41 Bcf, or 457 MMcf/d, from the HG Acquisition and 72 wells that were connected to our system between periods, increased gathering rates as a result of annual CPI-based adjustments, partially offset by the Utica Shale Divestiture and natural production decline of the wells connected to our system between periods .

● Compression revenue increased $5 million period over period primarily due to on-pad compression cost plus 3% fees from the HG Acquisition of $4 million and increased centralized compression rates as a result of annual CPI-based adjustments, as well as increased throughput volumes to centralized compression of 4 Bcf, or 40 MMcf/d. Centralized compression volumes increased between periods primarily due to 72 wells that were connected to our system between periods , partially offset by the Utica Shale Divestiture and natural production decline of the wells connected to our system between periods.

● High pressure gathering revenue increased $2 million period over period primarily due to increased high pressure gathering rates as a result of annual CPI-based adjustments, as well as increased throughput volumes of 2 Bcf, or 27 MMcf /d, primarily due to 72 wells that were connected to our system between periods, partially offset by the Utica Shale Divestiture and natural production decline of the wells connected to our system between periods.

[**Table of Contents**](#Toc)

● Amortization of customer relationships increased $3 million period over period due to a customer relationship intangible asset of approximately $555 million acquired in the HG Acquisition during the three months ended March 31, 2026.

*Water Handling*

● Fresh water delivery revenue decreased $8 million period over period primarily due to decreased fresh water delivery volumes of 2 MMBbl, or 22 MBbl/d, partially offset by an increase to the fresh water delivery rate as a result of the annual CPI-based adjustment. Water delivery volumes decreased between periods due to the timing of well completions by Antero Resources.

● Other water handling revenue increased $10 million period over period primarily due to higher other water handling volumes of 3 MMBbl, or 35 MBbl/d, as well as higher blending cost of service fees and increased costs for wastewater trucking and disposal volumes. Other water handling volumes increased between periods primarily due to 2 MMBbl of fresh water delivery volumes provided to Antero Resources on its acreage acquired from HG Production that are charged at cost plus 3% during the three months ended March 31, 2026.

*Direct operating expenses.* Direct operating expenses increased by 24%, from $57 million for the three months ended March 31, 2025 to $71 million for the three months ended March 31, 2026. Gathering and processing direct operating expenses increased by 15% from $26 million for the three months ended March 31, 2025 to $30 million for the three months ended March 31, 2026 primarily due to increased gathering volumes between periods related to the HG Acquisition. Water handling direct operating expenses increased by 33%, from $31 million for the three months ended March 31, 2025 to $41 million for the three months ended March 31, 2026 primarily due to fresh water delivery volumes provided by Antero Resources on acreage it acquired from HG Production, increased wastewater trucking and disposal volumes between periods and increased blending costs between periods.

*General and administrative (excluding equity-based compensation) expenses.* General and administrative expenses (excluding equity-based compensation expense) remained relatively consistent at $11 million and $12 million for each of the three months ended March 31, 2025 and 2026, respectively.

*Equity-based compensation expenses.* Equity-based compensation expenses remained relatively consistent at $12 million and $11 million for the three months ended March 31, 2025 and 2026, respectively. Our equity-based awards vest over three or four year service periods. See Note 11—Equity-Based Compensation to the unaudited condensed consolidated financial statements for additional information.

*Depreciation expense.* Depreciation expense increased by 6%, from $33 million for the three months ended March 31, 2025 to $35 million for the three months ended March 31, 2026 primarily due to incremental depreciation expense of $3 million related to gathering and water pipelines acquired in the HG Acquisition and assets placed in service during the year, partially offset by lower depreciation as a result of the Utica Shale Divestiture between periods.

*Loss (gain) on long-lived assets.* There were no long-lived asset sales during the three months ended March 31, 2025. During the three months ended March 31, 2026, we recognized a gain on long-lived assets of $3 million related to the Utica Shale Divestiture. See Note 3—Transactions to our condensed consolidated financial statements for additional information.

*Interest expense, net.* Interest expense, net increased by 12%, from $48 million for the three months ended March 31, 2025 to $54 million for the three months ended March 31, 2026 primarily due to issuance of the 2033 Notes and 2034 Notes during the second half of 2025, partially offset by the redemption of the 2027 Notes, lower average daily Credit Facility borrowings and higher interest income on cash equivalents and restricted cash between periods. See Note 9—Long-Term Debt to our unaudited condensed consolidated financial statements for additional information.

*Equity in earnings of unconsolidated affiliates.* Equity in earnings of unconsolidated affiliates increased by 7%, from $28 million for the three months ended March 31, 2025 to $30 million for the three months ended March 31, 2026 primarily due to increased processing volumes and higher processing and fractionation fees as a result of annual CPI-based adjustments between periods.

*Transaction expense.* During the three months ended March 31, 2026, we incurred $9 million of transaction expense related to the HG Acquisition. There were no transaction expenses during the three months ended March 31, 2025. See Note 3—Transactions to our unaudited condensed consolidated financial statements for additional information.

[**Table of Contents**](#Toc)

*Income tax expense.* Income tax expense increased by 4%, from $36 million for the three months ended March 31, 2025 to $38 million for the three months ended March 31, 2026, which reflects effective tax rates of approximately 23% and 24%, respectively. This income tax increase was primarily due to the effects of equity-based compensation expense between periods.

**Capital Resources and Liquidity**

***Sources and Uses of Cash***

Capital resources and liquidity are provided by operating cash flows, available borrowings under our Credit Facility and capital market transactions. See Note 9—Long-Term Debt to the unaudited condensed consolidated financial statements. We expect that the combination of these capital resources will be adequate to meet our working capital requirements, capital expenditures program and expected quarterly cash dividends for at least the next 12 months.

Our Board declared a cash dividend on the shares of our common stock of $0.225 per share for the quarter ended March 31, 2026. The dividend is payable on May 13, 2026 to stockholders of record as of April 29, 2026. Our Board also declared a cash dividend of $137,500 on the shares of Series A Preferred Stock that is payable on May 15, 2026 in accordance with their terms as discussed in Note 13—Equity and Net Income Per Common Share. As of March 31, 2026, there were dividends in the amount of $68,750 accumulated in arrears on our Series A Preferred Stock.

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

As of March 31, 2026, we did not have any off-balance sheet arrangements.

***Cash Flows***

The following table summarizes our cash flows for the three months ended March 31, 2025 and 2026:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,**  | **Three Months Ended March 31,**  |
| <br>**(in thousands)** | **2025** | **2026** |
| Net cash provided by operating activities | $198942 | 238624 |
| Net cash used in investing activities | (32271) | (780771) |
| Net cash provided by (used in) financing activities | (166671) | 279212 |
| &nbsp;&nbsp;&nbsp;&nbsp;Net decrease in cash, cash equivalents and restricted cash | $— | (262935) |

---

*Operating activities.* Net cash provided by operating activities was $199 million and $239 million for the three months ended March 31, 2025 and 2026, respectively. This increase in cash flows provided by operating activities between periods was primarily the result of lower cash used for working capital, increased gathering and processing and water handling revenues during the three months ended March 31, 2026, partially offset by increased gathering and processing and water handling direct operating expenses between periods.

*Investing activities.* Net cash flows used in investing activities was $32 million and $781 million for the three months ended March 31, 2025 and 2026, respectively. The increase in cash flows used in investing activities between periods was primarily due to cash paid for the HG Acquisition of $1.1 billion during the three months ended March 31, 2026, as well as increased capital spending for water handling systems of $10 million, partially offset by proceeds from the Utica Shale Divestiture of $379 million during the three months ended March 31, 2026.

*Financing activities.* Net cash used in financing activities was $167 million for the three months ended March 31, 2025 and net cash provided by financing activities was $279 million for the three months ended March 31, 2026, respectively. The increase in cash flows provided by financing activities between periods was primarily due to the increase in net borrowings on our Credit Facility of $449 million and lower share repurchases of $11 million between periods, partially offset by higher payments for employee tax withholding for settlement of equity-based compensation awards of $14 million.

***2026 Capital Investment***

On February 11, 2026, we announced our 2026 capital budget with a range of $190 million to $220 million. This capital budget supports Antero Resources' capital program for 2026. Our capital budget may be adjusted as business conditions warrant. Additionally, we monitor our existing assets and look for opportunities to reuse or otherwise repurpose assets in an effort to optimize our capital efficiency.

Our capital expenditures were as follows:

***Debt Agreements***

See Note 9—Long-Term Debt to the unaudited condensed consolidated financial statements and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our 2025 Form 10-K for additional information.

**Critical Accounting Estimates**

The discussion and analysis of our financial condition and results of operations are based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance with GAAP. Any new accounting policies or updates to existing accounting policies as a result of recently adopted accounting standards have been included in Note 2—Summary of Significant Accounting Policies to our unaudited condensed consolidated financial statements. The preparation of our unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent liabilities. Accounting estimates and assumptions are considered to be critical if there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the reported amounts in our unaudited condensed consolidated financial statements that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our unaudited condensed consolidated financial statements. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" included in the 2025 Form 10-K for additional information.

***Business Combinations***

We recognize and measure the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date, with any remaining difference recorded as goodwill. For acquisitions, management engages an independent valuation specialist to assist with the determination of fair value of the assets acquired, liabilities assumed, and goodwill, based on recognized valuation methodologies, including but not limited to cost and income approaches as circumstances warrant. 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, we will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the acquisition date. An adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period of the adjustment.

The valuation of the assets acquired and liabilities assumed in a business combination requires significant judgment about future events, economic and functional obsolescence, capacity and useful lives, among others, and such fair value approaches may rely on significant inputs that are not observable in the market. These assumptions affect the fair value of assets acquired and liabilities assumed and, if changed, could have a material effect on the Company's financial position or results of operations. See Note 3—Transactions and Note 14—Fair Value Measurement to our condensed consolidated financial statements for additional information.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk.**

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

**Commodity Price Risk**

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

**Interest Rate Risk**

Our primary exposure to interest rate risk results from outstanding borrowings under the Credit Facility, which has a floating interest rate. We do not currently, but may in the future, hedge the interest on portions of our borrowings under the Credit Facility from time-to-time in order to manage risks associated with floating interest rates. As of March 31, 2026, we had $442 million of borrowings and no letters of credit outstanding under the Credit Facility. A 1.0% increase in the Credit Facility interest rate would have resulted in an estimated $1 million increase in interest expense for the three months ended March 31, 2026.

**Credit Risk**

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

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

**Item 4. Controls and Procedures.** 

**Evaluation of Disclosure Controls and Procedures**

As required by Rule 13a-15(b) under the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2026 at a reasonable assurance level.

**Changes in Internal Control Over Financial Reporting**

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II—OTHER INFORMATION**

**Item 1. Legal Proceedings.**

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

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

See Note 16—Contingencies to the unaudited condensed consolidated financial statements for additional information.

**Item 1A. Risk Factors.**

We are subject to certain risks and hazards due to the nature of the business activities we conduct. For a discussion of these risks, see "Item 1A. Risk Factors" in the 2025 Form 10-K. There have been no material changes to the risks described in such report. We may experience additional risks and uncertainties not currently known to us. Furthermore, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect us.

**Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.**

**Issuer Purchases of Equity Securities**
