Revenue
Revenue	(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) the gathering and compression agreements acquired with the Crestwood Equity Partners LP (NYSE: CEQP) (“Crestwood”) assets (the “Marcellus gathering and compression agreements”) 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 agreements, the “gathering and compression agreements”). See Note 6—Property and Equipment for additional information. The 2019 gathering and compression agreement has an initial term through 2038, the Marcellus gathering and compression agreements expire between 2023 and 2031, and the Utica compression agreement has two dedicated areas that expire in 2024 and 2030. Upon expiration of each of the Marcellus gathering and compression service agreements 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 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. The 2019 gathering and compression agreement includes a growth incentive fee program whereby low pressure gathering fees will be reduced from 2020 through 2023 to the extent Antero Resources achieves certain quarterly volumetric targets during such time. Antero Resources’ throughput gathered under the Marcellus gathering and compression agreements is not considered in low pressure gathering volume targets. Antero Resources achieved the first level volumetric target during each of the first three quarters of 2022 and 2023. Accordingly, Antero Resources earned rebates of $ 30, 2022 and 2023. 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 either the Company or Antero Resources on or before the 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 certain of the Marcellus gathering and compression agreements include 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 , which election is made individually for each piece of equipment placed in service. In addition, certain of the Marcellus gathering and compression agreements provide for a minimum volume commitment that requires Antero Resources to utilize or pay for . 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 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. Minimum future lease cash flows to be received by the Company under the gathering and compression agreements as of September 30, 2023 are as follows (in thousands): ​ ​ ​ ​ ​ Remainder of year ending December 31, 2023 ​ $ 54,905 ​ Year ending December 31, 2024 ​ ​ 316,492 ​ Year ending December 31, 2025 ​ ​ 298,143 ​ Year ending December 31, 2026 ​ ​ 284,327 ​ Year ending December 31, 2027 ​ ​ 224,150 ​ Thereafter ​ ​ 382,435 ​ Total ​ $ 1,560,452 ​ ​ (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 either the Company or Antero Resources on or before the th day prior to the anniversary of such effective date. 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 . 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 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. (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.

Lessor, Operating Leases	(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) the gathering and compression agreements acquired with the Crestwood Equity Partners LP (NYSE: CEQP) (“Crestwood”) assets (the “Marcellus gathering and compression agreements”) 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 agreements, the “gathering and compression agreements”). See Note 6—Property and Equipment for additional information. The 2019 gathering and compression agreement has an initial term through 2038, the Marcellus gathering and compression agreements expire between 2023 and 2031, and the Utica compression agreement has two dedicated areas that expire in 2024 and 2030. Upon expiration of each of the Marcellus gathering and compression service agreements 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 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. The 2019 gathering and compression agreement includes a growth incentive fee program whereby low pressure gathering fees will be reduced from 2020 through 2023 to the extent Antero Resources achieves certain quarterly volumetric targets during such time. Antero Resources’ throughput gathered under the Marcellus gathering and compression agreements is not considered in low pressure gathering volume targets. Antero Resources achieved the first level volumetric target during each of the first three quarters of 2022 and 2023. Accordingly, Antero Resources earned rebates of $ 30, 2022 and 2023. 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 either the Company or Antero Resources on or before the 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 certain of the Marcellus gathering and compression agreements include 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 , which election is made individually for each piece of equipment placed in service. In addition, certain of the Marcellus gathering and compression agreements provide for a minimum volume commitment that requires Antero Resources to utilize or pay for . 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 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. Minimum future lease cash flows to be received by the Company under the gathering and compression agreements as of September 30, 2023 are as follows (in thousands): ​ ​ ​ ​ ​ Remainder of year ending December 31, 2023 ​ $ 54,905 ​ Year ending December 31, 2024 ​ ​ 316,492 ​ Year ending December 31, 2025 ​ ​ 298,143 ​ Year ending December 31, 2026 ​ ​ 284,327 ​ Year ending December 31, 2027 ​ ​ 224,150 ​ Thereafter ​ ​ 382,435 ​ Total ​ $ 1,560,452 ​ ​ (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 either the Company or Antero Resources on or before the th day prior to the anniversary of such effective date. 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 . 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 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.

All grants made prior to March 12, 2019 were fully amortized during the first quarter of 2023. Therefore, there will be no further allocation of equity-based compensation expense from Antero Resources to the Company. The Company does not reimburse Antero Resources for noncash equity compensation allocated to it for awards issued under the AR LTIP. AM LTIP Effective March 12, 2019, the Board of Directors of Antero Midstream Corporation (the “Board”) adopted the AM LTIP under which awards may be granted to employees, directors, and other service providers of the Company and its affiliates. The Company is authorized to grant up to shares of AM common stock to employees and directors under the AM LTIP. The AM LTIP provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), dividend equivalents, other stock-based awards, cash awards and substitute awards. The terms and conditions of the awards granted are established by the compensation committee of the Board of Directors (the “Board”).

The Converted AM RSU Awards were accounted for as if they were distributed by Antero Midstream Partners to Antero Resources. Therefore, the expense related to the Converted AM RSU Awards was subject to allocation by Antero Resources. All remaining Converted AM RSU Awards vested during the first quarter of 2023. ​ A summary of the RSU awards activity, which included the Converted AM RSU Awards, is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted Average ​ ​ ​ Number ​ Grant Date ​ ​ of Units Fair Value ​ Total AM LTIP RSUs awarded and unvested—December 31, 2022 ​ 4,877,258 ​ $ 9.79 ​ Granted ​ 3,103,722 ​ ​ 10.59 ​ Vested ​ (1,901,400) ​ ​ 9.59 ​ Forfeited ​ (170,365) ​ ​ 10.39 ​ Total AM LTIP RSUs awarded and unvested—September 30, 2023 ​ 5,909,215 ​ $ 10.26 ​ ​ As of September 30, 2023, unamortized equity-based compensation expense of $48 million related to the unvested RSUs is expected to be recognized over a weighted average period of 2.0 years.
