ANNUAL REPORT 
 
 
 
 
 
 
To Our 
Shareholders,

Since our IPO over a decade ago, our strategy has remained 
consistent: safely transport low-cost natural gas and natural 
gas liquids to growing demand both domestically and abroad. 
Our world-class assets and employees allow us to operate 
one of the most capital efficient midstream companies not 
only in Appalachia, but in North America. As the critical first 
link in supplying this increasing demand, Antero Midstream’s 
operations continue to play an increasing role as one of the 
leaders in low-cost energy.

Capital Efficient Growth

Our integrated gathering, compression and water handling 
assets delivered yet another record setting year, both 
financially and operationally. Our infrastructure transported 
over 3.4 Bcf/d of natural gas in 2025, a 5% year-over-year 
increase, representing approximately 3% of the U.S. natural 
gas market. This resulted in 7% EBITDA growth year-over-
year and marked our 11th consecutive year of EBITDA growth 
since our inception. Importantly, we delivered over 99% 
uptime availability, highlighting the consistency and reliability 
of our operations. Looking ahead, we expect natural gas 
demand growth from visible LNG export capacity buildout and 
increasing power needs for data centers and gas-fired power 
plants to drive additional growth opportunities for  
Antero Midstream.

Leader in Sustainability 

In 2025, Antero Midstream successfully completed 
our goal of eliminating emissions associated 
with our pipeline maintenance processes. 
After establishing this goal in 2019, we utilized 
operational efficiencies, emerging technology and 
cross-team collaboration to successfully achieve 
this important milestone. These meaningful 
changes will drive emissions reduction year-
over-year as we continue our commitment to 
responsible, sustainable midstream operations. 
Our extensive water management infrastructure 
continues to benefit both our operations and 
the communities where we work. By reducing 
the demand on local freshwater sources and 
eliminating truck traffic on local roads, we are able 
to improve the safety of residents and reduce local 
emissions. In 2025, we successfully transported 
and reused 15 million barrels of wastewater with a 
99% deliverability rate. 

We appreciate the support from our Board of 
Directors. We thank you, our shareholders, for your 
continued support of Antero Midstream and we look 
forward to further success for many years to come.

Michael Kennedy 
CEO & President

Expanding Assets in 
the Lowest Cost Basin 

In 2025, we invested approximately $180 million 
in gathering, compression and water handling 
assets. This included connectivity enhancements 
on our water handling system as well as the 
initial expansion of our dry gas gathering and 
compression assets acquired in 2022. These 
organic investments will enhance development 
optionality across our assets, setting the stage for 
future low-cost growth. In addition to our organic 
capital investments, Antero Midstream announced 
the acquisition of gathering and water handling 
assets focused in the core of the Marcellus Shale in 
West Virginia and the divestiture of non-core Utica 
Shale assets in Ohio. The acquired assets are a 
strategic fit within our portfolio and enhance both 
the EBITDA and Free Cash Flow growth outlook for 
the company. 

Capital Allocation 
Drives Shareholder 
Value

Our expanding Free Cash Flow allowed us to 
internally finance an attractive dividend, reduce 
absolute debt, and repurchase shares in 2025. This 
balanced capital allocation resulted in a 24% total 
shareholder return in 2025 and leverage declining 
below our 3.0x long-term target. In addition, we 
successfully refinanced our near-term senior note 
maturity and executed permanent financing for our 
acquisition, further improving the liquidity position 
and flexibility as we head into 2026.

SUMMARY RISK FACTORS 

Customer Concentration 

•  Because substantially all of our revenue is currently derived from Antero Resources, any development that materially 
and adversely affects Antero Resources’ operations, financial condition or market reputation could have a material and 
adverse impact on us. 

•  Because of the natural decline in production from existing wells, our success depends, in part, on Antero Resources’ 
ability to replace declining production and our ability to secure new sources of natural gas from Antero Resources or 
third parties.  Additionally, our water handling services are directly associated with Antero Resources’ well completion 
activities and water needs, which are largely driven by the amount of water used in completing each well.  Finally, under 
certain circumstances, Antero Resources may dispose of acreage dedicated to us free from such dedication without our 
consent.  Any decrease in volumes of natural gas that Antero Resources produces, any decrease in the number of wells 
that Antero Resources completes, or any decrease in the number of acres that are dedicated to us could adversely affect 
our business and operating results. 

Business Operations 

•  A material shut-in of production by Antero Resources or any of our other customers could adversely affect our business. 

•  Our gathering and compression agreements include minimum volume commitments only under certain circumstances. 

•  Our construction or purchase of new gathering and compression, processing, water handling or other assets may not be 
completed on schedule, at the budgeted cost or at all, may not operate as designed or at the expected levels, may not 
result in revenue increases and may be subject to regulatory, environmental, political, legal and economic risks, all of 
which could adversely affect our financial condition, cash flows and results of operations. 

•  Recent action and the possibility of future action on trade by U.S. and foreign governments has increased the costs of 
certain equipment and materials used in the construction of our assets and has created uncertainty in global markets, 
which may adversely affect our income from operations and cash flows. 

• 

If third-party pipelines or other midstream facilities interconnected to our gathering and compression systems become 
partially or fully unavailable, our operating margin and cash flows could be adversely affected. 

•  Our exposure to commodity price risk may change over time. 

•  The fees charged to our customers may not escalate sufficiently to cover increases in costs, or the agreements may be 

amended with less favorable terms, may not be renewed or may be suspended in some circumstances. 

•  Oil and natural gas producers’ operations, especially those using hydraulic fracturing, are substantially dependent on the 

availability of water. 

•  Sustainability matters and conservation measures may adversely impact our business. 

•  Our business involves many hazards and operational risks, some of which may not be fully covered by insurance.  The 
occurrence of a significant accident or other event that is not fully insured could curtail our operations and have a 
material adverse effect on our business, financial condition and results of operations. 

•  An impairment of our assets, including property and equipment and/or intangible assets, could reduce our earnings. 

Capital Structure and Access to Capital 

•  We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions 

to satisfy our obligations under our indebtedness or to refinance, which may not be successful. 

•  We will be required to make capital expenditures to increase our asset base.  If we cannot obtain needed capital or 

financing on satisfactory terms, we may be unable to expand our business operations and/or our financial leverage could 
increase. 

v 

Table of Contents  
•  Restrictions in our existing and future debt agreements could adversely affect our business, financial condition and 

results of operations. 

Acquisitions and Divestitures 

•  We may not achieve the intended benefits of the HG Acquisition, and the HG Acquisition may disrupt our existing plans 

or operations. 

•  We may not complete the Utica Shale Divestiture within the anticipated timeframe or at all. 

Joint Ventures 

•  We own a 50% interest in the Joint Venture, which is operated by MarkWest.  While we have the ability to influence 

certain business decisions affecting the Joint Venture, the success of our investment in the Joint Venture will depend on 
MarkWest’s operation of the Joint Venture. 

• 

If the Joint Venture is not successful or if the Joint Venture does not perform as expected, our future financial 
performance may be negatively impacted. 

Compliance with Regulations 

•  We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or 

feasibility of conducting our operations or expose us to significant liabilities. 

• 

• 

If our assets become subject to FERC regulation or federal, state or local regulations or policies change, or if we fail to 
comply with market behavior rules, our financial condition, cash flows and results of operations could be materially and 
adversely affected. 

Increased regulation of hydraulic fracturing could result in reductions or delays in production by our customers, which 
could reduce the throughput on our gathering and processing systems and the number of wells for which we provide 
water handling services, which could adversely impact our revenues. 

•  Our operations are subject to a series of risks related to climate that could result in increased operating costs, limit the 

areas in which our customers may conduct oil and gas exploration and production activities, and reduce demand for the 
services we provide. 

Related Parties 

•  Antero Resources owns a significant interest in us and, as a result, conflicts of interest will arise from time to time 

between it and us, and Antero Resources may favor their own interests to the detriment of us and our other stockholders.  
Additionally, Antero Resources is under no obligation to adopt a business strategy that favors us.

ITEMS 1 AND 2.  BUSINESS AND PROPERTIES  

Overview 

PART I 

Antero Midstream Corporation together with its consolidated subsidiaries (“Antero Midstream,” the “Company,” “we,” “us” 
or “our”) is a growth-oriented midstream energy company formed to own, operate and develop midstream energy assets that primarily 
service Antero Resources’ production and completion activity in the Appalachian Basin located in West Virginia and Ohio.  Our 
assets consist of gathering systems and compression facilities, water handling and blending facilities and interests in processing and 
fractionation plants.  We conduct our operations and own our operating assets and ownership interests in the Joint Venture and 
Stonewall through Antero Midstream Partners and its subsidiaries, all of which are wholly-owned.  Additionally, Antero Resources 
has a 29% ownership interest in us as of December 31, 2025.  Unless expressly stated otherwise, the operating and financial 
information presented in this Annual Report on Form 10-K does not give effect to the HG Acquisition or the Utica Shale Divestiture. 

Business Strategy and Competitive Strengths 

Experienced Management Team 

Our management team has worked together for many years and has established a successful track record of developing 

integrated business models that are capable of delivering consistent returns on invested capital.  We intend to leverage our 
management team’s significant industry expertise and experience developing natural gas resource plays to continue building out our 
premier midstream system. 

Fixed Fee Business with Long-Term Contracts 

We provide gathering, compression, processing, fractionation and integrated water services to Antero Resources under long-

term, fixed-fee and cost of service fee contracts with certain minimum volume commitments, limiting our direct exposure to 
commodity price risk.  We have agreements in place to provide gathering and compression services through 2038 and water services 
through 2035. 

Integrated Business Model  

We believe that our strategically located assets and our relationship with Antero Resources have allowed us to become a 

leading midstream energy company serving the Appalachian Basin.  Our significant investment in West Virginia and Ohio 
infrastructure makes us well positioned to expand our operations in a capital efficient manner. 

Disciplined Capital Investment 

We utilize a flexible, just-in-time capital budgeting approach through integrated planning with Antero Resources, which allows 
us to avoid long lead-times in our capital investments in order to maximize our asset utilization and returns on invested capital.  We 
believe this just-in-time capital investment approach is unique to Antero Midstream and allows us to generate consistent free cash flow. 

Strong Balance Sheet and Sustainable Leverage Profile 

We are focused on maintaining a strong balance sheet, which includes maintaining a sustainable leverage profile.  In recent 

years, we have significantly reduced our leverage profile and will prioritize it on an ongoing basis. 

Operating Segments 

Our operations are located in the United States and are organized into two reportable segments: (1) gathering and processing 

and (2) water handling.  Financial information for our reportable segments is located under Note 17—Reportable Segments to our 
consolidated financial statements.

Acquisitions 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 Energy II Midstream Holdings, LLC (“HG Midstream”) from HG Energy II LLC (“HG Energy”) for cash consideration of $1.1 
billion, subject to the terms and conditions thereof.  The HG Acquisition includes gathering pipelines and integrated water handling 
assets in the core of the Marcellus Shale in West Virginia.  Pursuant to the same agreement, Antero Resources agreed to acquire 100% 
of the issued and outstanding equity interests of HG Energy II Production Holdings, LLC (“HG Production”) from HG Energy for 
total cash consideration of $2.8 billion, subject to the terms and conditions thereof (the “HG Upstream Acquisition”).  The HG 
Upstream Acquisition includes approximately 385,000 net acres in the core of the Marcellus Shale in West Virginia.  These 
acquisitions closed on February 3, 2026.  See Note 3—Transactions to our consolidated financial statements for additional 
information. 

Summit Asset Acquisition 

On May 1, 2024, we acquired certain Marcellus Shale gas gathering and compression assets from Summit Midstream 
Partners, LP (NYSE: SMLP) (“Summit”) for $70 million in cash, before closing adjustments, with an effective date of April 1, 2024.  
The acquired assets include 48 miles of high pressure gathering pipelines and two compressor stations with 100 MMcf/d of 
compression capacity.  These assets were already interconnected to our low pressure and high pressure gas gathering systems at the 
time of acquisition and service Antero Resources’ production.  Currently, we do not expect to make any significant capital 
investments related to the acquired assets.  See Note 3—Transactions to our consolidated financial statements for additional 
information. 

Utica Shale Divestiture 

On December 5, 2025, we entered into a definitive agreement with two third-party buyers (collectively, the “Buyer Parties”) 
to sell substantially all of our Utica Shale midstream assets located in Ohio (the “Utica Shale Property and Equipment”), for aggregate 
cash consideration of $400 million, subject to the terms and conditions thereof.  The Utica Shale Property and Equipment includes 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 is expected to close in February 2026, subject to the 
satisfaction of certain customary closing conditions.  See Note 3—Transactions to our consolidated financial statements for additional 
information. 

Our Assets  

Our gathering and processing assets consist of high and low pressure gathering pipelines, compressor stations and processing 
and fractionation plants that collect and process natural gas and NGLs from Antero Resources’ wells in West Virginia and Ohio.  Our 
water handling assets include two independent systems that deliver water from sources, including the Ohio River, local reservoirs and 
several regional waterways.  Portions of these systems are also utilized to transport flowback and produced water.  The water handling 
systems consist of permanent buried pipelines, surface pipelines and water storage facilities, as well as pumping stations, blending 
facilities and impoundments to transport water throughout the systems used to deliver water to Antero Resources’ well completions.

During the year ended December 31, 2025, we added 13 miles of low pressure pipeline, 10 miles of high pressure pipeline, 
three miles of buried water pipeline and 24 miles of surface water pipeline in the Appalachian Basin.  In addition, our compression 
capacity increased by 0.2 Bcf/d during the year ended December 31, 2025 as a result of our program to repurpose underutilized 
compressor units to expand existing or construct new compressor stations.  As of December 31, 2025, we had 33 water impoundments 
with storage capacity of approximately 5 million barrels.  Additionally, we built water blending and storage infrastructure to support 
other fluid handling services that we provide to Antero Resources for well completion and production activities.  We also own water 
treatment assets, including the Antero Clearwater Facility (the “Clearwater Facility”), which we idled in September 2019.  Since

idling the Clearwater Facility, we have satisfied our obligation to handle Antero Resources’ flowback and produced water through our 
other fluid handling services. 

Our Relationship with Antero Resources  

Antero Resources is our most significant customer and is one of the largest producers of natural gas and NGLs in North 

America.  As of December 31, 2025, substantially all of Antero Resources’ approximate 566,000 gross acres (537,000 net acres) are 
dedicated to us for gathering, compression and water services.  During the year ended December 31, 2025, Antero Resources 
produced, on average, 3.4 Bcfe/d net (36% liquids).  As of December 31, 2025, Antero Resources’ estimated net proved reserves were 
19.1 Tcfe, which were comprised of 61% natural gas, 38% NGLs and 1% oil.  Antero Resources has a vast drilling inventory of 
horizontal well locations in the Appalachian Basin (all of which are on acreage dedicated to us) for gathering and compression and 
water handling services, which provides us with significant opportunities for growth as Antero Resources’ active development 
program continues. 

Antero Resources announced its 2026 drilling and completion budget is $1.0 billion to $1.2 billion, and includes plans to 

complete 70 to 80 net horizontal wells in the Appalachian Basin.  In addition, Antero Resources’ 2026 capital budget includes $100 
million for leasehold expenditures, all of which will be dedicated to us.  Antero Resources’ 2026 capital budget reflects the closing of 
the HG Upstream Acquisition on February 3, 2026 and assumes the closing of the divestiture of its Utica Shale oil and gas assets 
during February 2026.  Antero Resources relies significantly on us to deliver the midstream infrastructure necessary to accommodate 
its development program.  For additional information regarding our contracts with Antero Resources, see “—Operational and 
Managerial Arrangements with Antero Resources.” 

We currently derive substantially all of our revenue from Antero Resources.  Any development that materially and adversely 

affects Antero Resources’ operations, financial condition or market reputation could have a material adverse impact on us.  
Accordingly, we are indirectly subject to the business risks of Antero Resources.  For additional information, see “Item 1A.  Risk 
Factors—Customer Concentration.” 

Operational and Managerial Arrangements with Antero Resources 

Gathering and Compression 

Our gathering and compression service agreements with Antero Resources include: (i) the second amended and restated 

gathering and compression agreement dated December 8, 2019 (the “2019 gathering and compression agreement”), (ii) a gathering 
and compression agreement acquired with the Crestwood Equity Partners LP (“Crestwood”) assets (the “Marcellus gathering and 
compression agreement”), (iii) a compression agreement acquired with the EnLink Midstream LLC (NYSE: ENLC) (“EnLink”) assets 
(the “Utica compression agreement”) and (iv) a gathering and compression agreement acquired with the Summit assets (the 
“Mountaineer gathering and compression agreement,” and together with the 2019 gathering and compression agreement, the 
Marcellus gathering and compression agreement and the Utica compression agreement, the “gathering and compression agreements”).  
See Note 3—Transactions and Note 6—Revenue to our consolidated financial statements for additional information.  Pursuant to these 
gathering and compression agreements, Antero Resources has dedicated substantially all of its current and future acreage in West 
Virginia, Ohio and Pennsylvania to us 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, and the Utica compression agreement has two acreage dedications, one of which expired in 2024 
and one that expires in 2030.  Upon expiration of the Marcellus gathering and compression agreement, the Utica compression 
agreement and the Mountaineer gathering and compression agreement, we will continue to provide gathering and compression 
services under the 2019 gathering and compression agreement.  We also have an option to gather and compress natural gas produced 
by Antero Resources on any undedicated acreage it acquires in the future outside of West Virginia, Ohio and Pennsylvania on the 
same terms and conditions as the 2019 gathering and compression agreement.  The Utica compression agreement is included in the 
Utica Shale Divestiture. 

Under the gathering and compression agreements, we receive a low pressure gathering fee per Mcf, a high pressure gathering 

fee per Mcf and a compression fee per Mcf, as applicable, subject to annual CPI-based adjustments.  We intend to make certain 
modifications to our existing commercial arrangements with Antero Resources to provide for on-pad compression with respect to 
certain wells.  If and to the extent Antero Resources requests that we construct new low pressure lines, high pressure lines and/or 
compressor stations, our 2019 gathering and compression agreement contains options at our election for either (i) minimum volume 
commitments that require Antero Resources to utilize or pay for 75% of the high pressure gathering capacity and 70% of the 
compression capacity of such new construction for 10 years or (ii) a cost of service fee that allows us to earn a 13% rate of return on 
such new construction over seven years, which election is made individually for each piece of equipment placed in service.  The 
Marcellus gathering and compression agreement provides for a minimum volume commitment that requires Antero Resources to 

3 

Table of Contents  
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 compressor station or high pressure 
gathering line, respectively, for a period of 12 years commencing 90 days after such asset’s in-service date.  As of December 31, 2025, 
the minimum volume commitments for the 2019 gathering and compression agreement end in 2035, and the minimum gathering and 
compression fees for the Mountaineer gathering and compression agreement end in 2026.  As of January 1, 2025, there were no 
minimum volume commitments under the Marcellus gathering and compression agreement.  Additional gathering lines and 
compressor stations installed on our own initiative are not subject to these minimum volume commitments or cost of service fee 
options.  These minimum volume commitments and rate of return options are intended to support the stability of our cash flows. 

Water Handling Services 

Pursuant to the water services agreement, we provide certain water handling services to Antero Resources within an area of 

dedication in defined service areas in Ohio and West Virginia.  We also have certain rights of first offer with respect to water services 
for acreage located outside of the existing dedicated areas.  Antero Resources agreed to pay us for all water handling services provided 
by us in accordance with the terms of the water services agreement, under which Antero Resources has no minimum volume 
commitments.  Under the agreement, Antero Resources will pay, and therefore we will receive, a fixed fee for all fresh water 
deliveries by pipeline directly to the well site, subject to annual CPI-based adjustments.  Antero Resources also agreed to pay us a 
fixed fee per barrel for water treatment at the Clearwater Facility, which was idled in the third quarter of 2019 and we expect will 
remain idled for the foreseeable future.  In addition, we also provide other fluid handling services.  These operations, along with our 
fresh water delivery systems, support well completion and production operations for Antero Resources.  These services are provided 
by us directly or through third-parties with which we contract.  For other fluid handling services provided by third parties, Antero 
Resources reimburses our third-party out-of-pocket costs plus 3%.  For other fluid handling services provided by us, we charge Antero 
Resources a cost of service fee.  The initial term of the water services agreement runs to 2035. 

We intend to make certain modifications to our water services agreement to provide a transition period through 2026 before 

certain water services would be provided to Antero Resources for the assets acquired from HG Production. 

Gas Processing and NGLs Fractionation 

The Joint Venture was formed in February 2017 to develop processing and fractionation assets in Appalachia.  In connection 

with our entry into the Joint Venture with MarkWest, we released to the Joint Venture our right to provide certain processing and 
fractionation services on 195,000 gross acres held by Antero Resources in the Appalachian Basin.  We have a right-of-first-offer 
agreement with Antero Resources for the provision of processing and fractionation services pursuant to which Antero Resources, 
subject to certain exceptions, may not procure any gas processing or NGLs fractionation services with respect to its production (other 
than production subject to a pre-existing dedication) without first offering us the right to provide such services. 

Secondment and Services Agreements 

Pursuant to a secondment agreement and a services agreement, Antero Resources seconds employees to us to provide 

operational services with respect to our assets and certain corporate, general and administrative services in exchange for 
reimbursement of any direct expenses and an allocation of any indirect expenses attributable to its provision of such services.  These 
agreements extend through 2039. 

Acreage Dispositions 

Antero Resources may sell, transfer, convey, assign, grant or otherwise dispose of dedicated properties free of the dedication 

under our gathering and compression, water services and right-of-first-offer agreements, provided that the number of net acres of 
dedicated properties so disposed of, when added to the number of net acres of dedicated properties previously disposed of free of the 
dedication since the respective effective dates of the agreements, does not exceed the aggregate number of net acres of dedicated 
properties acquired by Antero Resources since such effective dates.  Accordingly, under certain circumstances, Antero Resources may 
dispose of a significant number of net acres of dedicated properties free from dedication without our consent, and we have no control 
over the timing or extent of such dispositions. 

4 

Table of Contents  
Title to Properties 

Our real property is classified into two categories: (i) parcels that we own in fee and (ii) parcels in which our interest derives 

from leases, easements, rights-of-way, permits or licenses from landowners or governmental authorities, permitting the use of such 
land for our operations.  Portions of the land on which our pipelines and major facilities are located are owned by us in fee title, and 
we believe that we have satisfactory title to these lands.  The remainder of the land on which our pipelines and major facilities are 
located are held by us pursuant to surface leases between us, as lessee, and the fee owner of the lands, as lessors.  We have leased or 
owned these lands without any material challenge known to us relating to the title to the land upon which the assets are located, and 
we believe that we have satisfactory leasehold estates or fee ownership of such lands.  We have no knowledge of any challenge to the 
underlying fee title of any material lease, easement, right-of-way, permit or license held by us or to our title to any material lease, 
easement, right-of-way, permit or lease, and we believe that we have satisfactory title to all of our material leases, easements, 
rights-of-way, permits and licenses. 

Seasonality 

Demand for natural gas generally decreases during the spring and fall months and increases during the summer and winter 

months.  However, cold winters, hot summers or severe weather events can significantly increase demand and price fluctuations, while 
seasonal anomalies, such as mild winters, mild summers or severe weather events, can sometimes lessen the impact of these 
fluctuations.  In addition, certain natural gas end users, utilities and marketers utilize natural gas storage facilities and purchase some 
of their anticipated winter requirements during the spring, summer and fall, thereby smoothing demand for natural gas.  This can also 
lessen seasonal demand fluctuations.  These seasonal anomalies can increase demand for our services during the summer and winter 
months and decrease demand for our services during the spring and fall months. 

Competition 

As a result of our relationship with Antero Resources, we do not compete for the portion of Antero Resources’ existing 

operations for which we currently provide midstream services and will not compete for future portions of Antero Resources’ 
operations that are dedicated to us pursuant to: (i) our gathering and compression agreements; (ii) our water handling services 
agreement; and (iii) our right-of-first-offer agreement with Antero Resources for the provision of processing and fractionation 
services.  For a description of these contracts, see “—Our Relationship with Antero Resources—Operational and Managerial 
Arrangements with Antero Resources.”  However, we face competition in attracting third-party volumes to our gathering and 
compression and water handling systems.  In addition, these third parties may develop their own gathering and compression and water 
handling systems in lieu of employing our assets. 

Regulation of Operations 

Regulation of pipeline gathering services may affect certain aspects of our business and the market for our services. 

Gathering Pipeline Regulation 

Section 1(b) of the Natural Gas Act of 1938 (“NGA”), exempts natural gas gathering facilities from regulation by the FERC, 
under the NGA.  Although the FERC has not made any formal determinations with respect to any of our facilities, we believe that the 
natural gas pipelines in our gathering systems meet the traditional tests the FERC has used to establish whether a pipeline is a 
gathering pipeline not subject to FERC jurisdiction.  The distinction between FERC-regulated transmission services and federally 
unregulated gathering services, however, has been the subject of substantial litigation, and the FERC determines whether facilities are 
gathering facilities on a case-by-case basis, so the classification and regulation of some our gathering facilities and intrastate 
transportation pipelines may be subject to change based on future determinations by the FERC, the courts or Congress.  If the FERC 
were to consider the status of an individual facility and determine that the facility is not a gathering pipeline and the pipeline provides 
interstate transmission service, the rates for, and terms and conditions of, services provided by such facility would be subject to 
regulation by the FERC under the NGA or the Natural Gas Policy Act of 1978 (“NGPA”).  Such FERC-regulation could decrease 
revenue, increase operating costs, and, depending upon the facility in question, could adversely affect our results of operations and 
cash flows.  In addition, if any of our facilities were found to have provided services or otherwise operated in violation of the NGA or 
NGPA, this could result in the imposition of civil penalties as well as a requirement to disgorge charges collected for such service in 
excess of the rate established by the FERC. 

Unlike natural gas gathering under the NGA, there is no exemption for the gathering of crude oil or NGLs under the 

Interstate Commerce Act (“ICA”).  Whether a crude oil or NGLs shipment is in interstate commerce under the ICA depends on the 
fixed and persistent intent of the shipper as to the crude oil’s or NGLs’ final destination, absent a break in the interstate movement.  
Antero Midstream believes that the crude oil and NGLs pipelines in its gathering system meet the traditional tests the FERC has used 

5 

Table of Contents  
to determine that a pipeline is not providing transportation service in interstate commerce subject to FERC ICA jurisdiction.  
However, the determination of the interstate or intrastate character of shipments on Antero Midstream’s crude oil and NGLs pipelines 
depends on the shipper’s intentions and the transportation of the crude oil or NGLs outside of Antero Midstream’s system, and may 
change over time.  If the FERC were to consider the status of an individual facility and the character of a crude oil or NGLs shipment, 
and determine that the shipment is in interstate commerce, the rates for, and terms and conditions of, transportation services provided 
by such facility would be subject to regulation by the FERC under the ICA.  Such FERC regulation could decrease revenue, increase 
operating costs and, depending on the facility in question, could adversely affect Antero Midstream’s results of operations and cash 
flows.  In addition, if any of Antero Midstream’s facilities were found to have provided services or otherwise operated in violation of 
the ICA, this could result in the imposition of administrative and civil remedies and criminal penalties, as well as a requirement to 
disgorge charges collected for such services in excess of the rate established by the FERC. 

State regulation of gathering facilities generally includes various safety, environmental and, in some circumstances, 

nondiscriminatory take requirements and complaint-based rate regulation.  States in which we operate may adopt ratable take and 
common purchaser statutes, which would require our gathering pipelines to take natural gas without undue discrimination in favor of 
one producer over another producer or one source of supply over another similarly situated source of supply.  The regulations under 
these statutes may have the effect of imposing some restrictions on our ability as an owner of gathering facilities to decide with whom 
we contract to gather natural gas.  States in which we operate may also adopt a complaint-based regulation of natural gas gathering 
activities, which allows natural gas producers and shippers to file complaints with state regulators in an effort to resolve grievances 
relating to gathering access and rate discrimination.  We cannot predict whether such regulation will be adopted and whether such a 
complaint will be filed against us in the future.  Failure to comply with state regulations can result in the imposition of administrative, 
civil and criminal remedies.  To date, there has been no adverse effect to our system due to state regulations. 

Our gathering operations could be adversely affected should they be subject in the future to more stringent application of 

state regulation of rates and services.  Our gathering operations also may be, or become, subject to additional safety and operational 
regulations relating to the design, installation, testing, construction, operation, replacement and management of gathering facilities.  
Additional rules and legislation pertaining to these matters are considered or adopted from time to time.  We cannot predict what 
effect, if any, such changes might have on our operations, but the industry could be required to incur additional capital expenditures 
and increased costs depending on future legislative and regulatory changes. 

The Energy Policy Act of 2005 (“EPAct 2005”), amended the NGA and NGPA to prohibit fraud and manipulation in natural 
gas markets.  The FERC subsequently issued a final rule making it unlawful for any entity, in connection with the purchase or sale of 
natural gas or transportation service subject to FERC’s jurisdiction, to defraud, make an untrue statement or omit a material fact or 
engage in any practice, act or course of business that operates or would operate as a fraud.  The FERC’s anti-manipulation rules apply 
to intrastate sales and gathering activities only to the extent that there is a “nexus” to FERC-jurisdictional transactions.  EPAct 2005 
also provided the FERC with the authority to impose civil penalties of up to approximately $1 million (adjusted annually for inflation) 
per day per violation.   

In January 2025, FERC issued an order (Order No. 906) increasing the maximum civil penalty amounts under the NGA and 
NGPA to adjust for inflation.  FERC may now assess civil penalties under the NGA and NGPA of up to $1,584,648 per violation per 
day. 

Pipeline Safety Regulation 

Some of our gas pipelines are subject to regulation by the Pipeline and Hazardous Materials Safety Administration 

(“PHMSA”), pursuant to the Natural Gas Pipeline Safety Act of 1968 (“NGPSA”), with respect to natural gas, and the Hazardous 
Liquids Pipeline Safety Act of 1979 (“HLPSA”), with respect to crude oil and NGLs.  Both the NGPSA and the HLPSA were 
amended by the Pipeline Safety Act of 1992, the Accountable Pipeline Safety and Partnership Act of 1996, the Pipeline Safety 
Improvement Act of 2002 (“PSIA”), as reauthorized and amended by the Pipeline Inspection, Protection, Enforcement and Safety Act 
of 2006, the Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011 (“2011 Pipeline Safety Act”) and the Protecting Our 
Infrastructure of Pipelines and Enhancing Safety (“PIPES”) Act of 2020.  The NGPSA and HLPSA regulate safety requirements in the 
design, construction, operation and maintenance of natural gas, crude oil and NGLs pipeline facilities, while the PSIA establishes 
mandatory inspections for all U.S. crude oil, NGLs and natural gas transmission pipelines in certain high risk areas, such as high-
consequence areas (“HCAs”) or moderate consequence areas (“MCAs”). 

6 

Table of Contents  
The PHMSA has developed regulations that require pipeline operators to implement integrity management programs, 
including more frequent inspections and other measures to ensure pipeline safety in HCAs and MCAs.  The regulations require 
operators, including us, to: 

• 

• 

• 

• 

• 

perform ongoing assessments of pipeline integrity; 

identify and characterize applicable threats to pipeline segments that could impact certain high risk areas; 

improve data collection, integration and analysis; 

repair and remediate pipelines as necessary; and 

implement preventive and mitigating actions. 

The 2011 Pipeline Safety Act, among other things, increased the maximum civil penalty for pipeline safety violations and 
directed the Secretary of Transportation to promulgate rules or standards relating to expanded integrity management requirements, 
automatic or remote-controlled valve use, excess flow valve use, leak detection system installation and testing to confirm the material 
strength of pipe operating above 30% of specified minimum yield strength in HCAs.  Consistent with the 2011 Pipeline Safety Act, 
PHMSA finalized rules that increased the maximum administrative civil penalties for violation of the pipeline safety laws and 
regulations to $200,000 per violation per day, with a maximum of $2,000,000 for a related series of violations.  In December 2024, 
those maximum civil penalties were increased to $272,926 and $2,729,245, respectively, to account for inflation.  The PHMSA has 
also issued a final rule applying safety regulations to certain rural low-stress hazardous liquid pipelines that were not covered 
previously by some of its safety regulations. 

Following legislation enacted by Congress, PHMSA has issued or proposed regulations that either seek to impose new 

obligations on pipeline operations or expand existing pipeline safety requirements to previously unregulated pipelines.  For example, 
in November 2021, PHMSA issued a final rule that imposes safety regulations on approximately 400,000 miles of previously 
unregulated onshore gas gathering lines that, among other things, will impose criteria for inspection and repair of fugitive emissions, 
extend reporting requirements to all gas gathering operators and apply a set of minimum safety requirements to certain gas gathering 
pipelines with large diameters and high operating pressures.  In August 2022, PHMSA finalized the rule entitled “Pipeline Safety: 
Safety of Gas Transmission Pipelines, Repair Criteria, Integrity Management Improvements, Cathodic Protection, Management of 
Change and Other Related Amendments,” which adjusted the repair criteria for pipelines in HCAs, created new criteria for pipelines 
in non-HCAs and strengthened integrity management assessment requirements, among other items.  However, in August 2024, the 
U.S. Court of Appeals for the D.C. Circuit vacated various aspects of the 2022 rule.  Additionally, in April 2024, PHMSA 
promulgated a final rule that amended Federal pipeline safety regulations to incorporate more than 20 new or updated voluntary, 
consensus industry technical standards to allow pipeline operators to use current technologies and improved materials.  Further, in 
January 2025, PHMSA finalized a rule that enhances the safety requirements for gas distribution pipelines and requires updates to 
distribution integrity management programs, emergency response plans, operations and maintenance manuals and other safety 
practices.  However, the Trump administration withdrew the final rule shortly thereafter, and, accordingly, it has not been codified.  
These new and any future regulations adopted by PHMSA have imposed and may impose more stringent requirements applicable to 
integrity management programs and other pipeline safety aspects of our operations, which could cause us to incur increased capital 
and operating costs and operational delays. 

States are largely preempted by federal law from regulating pipeline safety for interstate lines but most are certified by the 
DOT to assume responsibility for enforcing federal intrastate pipeline regulations and inspection of intrastate pipelines.  States may 
adopt stricter standards for intrastate pipelines than those imposed by the federal government for interstate lines; however, states vary 
considerably in their authority and capacity to address pipeline safety.  State standards may include requirements for facility design 
and management in addition to requirements for pipelines.  We do not anticipate any significant difficulty in complying with 
applicable state laws and regulations. 

We regularly review all existing and proposed pipeline safety requirements and work to incorporate the new requirements 

into procedures and budgets.  We expect to incur increasing regulatory compliance costs, based on the intensification of the regulatory 
environment and upcoming changes to regulations as outlined above, consistent with other similarly situated midstream companies.  
In addition to regulatory changes, costs may be incurred if there is an accidental release of a commodity transported by our system, or 
a regulatory inspection identifies a deficiency in our required programs and corrective action is required.

Regulation of Environmental and Occupational Safety and Health Matters 

General 

Our natural gas gathering and compression and water handling activities are subject to stringent and complex federal, state 

and local laws and regulations relating to the protection of the environment, natural resources and worker safety.  As an owner or 
operator of these facilities, we must comply with these laws and regulations at the federal, state and local levels.  These laws and 
regulations can restrict or impact our business activities in many ways, such as: 

• 

• 

• 

• 

• 

requiring the installation of pollution-control equipment, imposing emission or discharge limits or otherwise restricting 
the way we operate resulting in additional costs to our operations; 

limiting or prohibiting construction activities in areas, such as air quality nonattainment areas, wetlands, coastal regions 
or areas inhabited by endangered or threatened species; 

delaying system modification or upgrades during review of permit applications and revisions; 

requiring investigatory and remedial actions to mitigate discharges, releases or pollution conditions associated with our 
operations or attributable to former operations; and 

enjoining the operations of facilities deemed to be in non-compliance with permits issued pursuant to or regulatory 
requirements imposed by such environmental laws and regulations. 

Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement 

measures, including the assessment of monetary penalties and natural resource damages.  Certain environmental statutes impose strict 
joint and several liability for costs required to clean up and restore sites where hazardous substances, hydrocarbons or solid wastes 
have been disposed or otherwise released.  Moreover, neighboring landowners and other third parties may file common law claims for 
personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or solid waste into the 
environment. 

The trend in environmental regulation has been to place more restrictions and limitations on activities that may affect the 

environment and thus, there can be no assurance as to the amount or timing of future expenditures for environmental compliance or 
remediation and actual future expenditures may be different from the amounts we currently anticipate.  As with the midstream 
industry in general, complying with current and anticipated environmental laws and regulations can increase our capital costs to 
construct, maintain and operate equipment and facilities.  While these laws and regulations affect our maintenance capital 
expenditures and net income, we do not believe they will have a material adverse effect on our business, financial position, results of 
operations or cash flows, nor do we believe that they will affect our competitive position since the operations of our competitors are 
generally similarly affected.  In addition, we believe that the various activities in which we are presently engaged that are subject to 
environmental laws and regulations are not expected to materially interrupt or diminish our operational ability to gather natural gas 
and provide water handling services.  We cannot assure you, however, that future events, such as changes in existing laws or 
enforcement policies, the promulgation of new laws or regulations or the development or discovery of new facts or conditions will not 
cause us to incur significant costs.  Below is a discussion of the material environmental laws and regulations that relate to our 
business.  

Hydraulic Fracturing Activities  

Hydraulic fracturing is an important and common practice that is used to stimulate production of natural gas and/or oil from 

dense subsurface rock formations.  The hydraulic fracturing process involves the injection of water, sand and chemicals under pressure 
through a cased and cemented wellbore into targeted subsurface formations to fracture the surrounding rock and stimulate production.  
Our primary customer, Antero Resources, uses the water we deliver to it for hydraulic fracturing as part of its completion operations 
as does most of the U.S. onshore oil and natural gas industry.  Hydraulic fracturing is typically regulated by state oil and gas 
commissions and similar agencies; however, in recent years the EPA has asserted limited authority over hydraulic fracturing pursuant 
to the federal Safe Drinking Water Act (“SDWA”) and has issued or sought to propose rules related to the control of air emissions, 
disclosure of chemicals used in the process and the disposal of flowback and produced water resulting from the process.  Some states, 
including those in which we operate, have adopted and other states are considering adopting, regulations that could impose more 
stringent disclosure and/or well construction requirements on hydraulic fracturing operations.  For example, both West Virginia and 
Ohio have adopted requirements governing well pad construction, as well as requiring oil and natural gas operators to disclose 
chemical ingredients used to hydraulically fracture wells and to conduct pre-drilling baseline water quality sampling of certain water 
wells near a proposed horizontal well.  Local governments also may seek to adopt ordinances within their jurisdictions regulating the 

8 

Table of Contents  
time, place and manner of drilling activities in general or hydraulic fracturing activities in particular.  Some states and municipalities 
have sought to ban hydraulic fracturing altogether.  In addition, Congress has from time to time considered legislation to provide for 
federal regulation of hydraulic fracturing under the SDWA and to require disclosure of the chemicals used in the hydraulic fracturing 
process.  We cannot predict whether any such federal, state or local legal restrictions relating to the hydraulic fracturing process will 
ever be enacted in areas where our customers operate and if so, what the effects of such restrictions would be.  If additional levels of 
regulation and permits were required through the adoption of new laws and regulations at the federal state or local level, that could 
lead to delays, increased operating costs and process prohibitions that could reduce the volumes of water and natural gas that move 
through our systems, which in turn could materially adversely affect our revenues and results of operations. 

Hazardous Waste 

Antero Midstream and Antero Resources’ operations generate solid wastes, including small quantities of hazardous wastes, 

that are subject to the federal Resource Conservation and Recovery Act (“RCRA”), and comparable state laws, which impose 
requirements for the handling, storage, treatment and disposal of hazardous waste.  RCRA currently exempts many oil and natural gas 
gathering and field processing wastes from classification as hazardous waste.  Specifically, RCRA excludes from the definition of 
hazardous waste produced waters and other wastes intrinsically associated with the exploration, development or production of crude 
oil and natural gas, including residual constituents derived from those exempt wastes.  However, these oil and gas exploration and 
production wastes may still be regulated under state solid waste laws and regulations and it is possible that certain oil and natural gas 
exploration and production wastes now classified as exploration and production-exempt non-hazardous waste could be classified as 
hazardous waste in the future.  Stricter regulation of wastes generated during our or our customers’ operations could result in 
increased costs for our operations or the operations of our customers, which could in turn reduce demand for our services, increase our 
waste disposal costs and adversely affect our business. 

Site Remediation  

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as the Superfund 

law, and comparable state laws impose liability without regard to fault or the legality of the original conduct, on certain classes of 
persons responsible for the release of hazardous substances into the environment.  Such classes of persons include the current and past 
owners or operators of sites where a hazardous substance was released and companies that disposed or arranged for disposal of 
hazardous substances at offsite locations, such as landfills.  Although petroleum as well as natural gas is excluded from CERCLA’s 
definition of “hazardous substance,” in the course of our ordinary operations, our operations generate wastes that may be designated as 
hazardous substances.  CERCLA authorizes the EPA, states, and, in some cases, third parties to take actions in response to releases or 
threatened releases of hazardous substances into the environment and to seek to recover from the classes of responsible persons the 
costs they incur to address the release.  Under CERCLA, we could be subject to strict joint and several liabilities for the costs of 
cleaning up and restoring sites where hazardous substances have been released into the environment and for damages to natural 
resources. 

We currently own or lease, and may have in the past owned or leased, properties that have been used for the gathering and 
compression of natural gas and the gathering and transportation of oil.  Although we typically used operating and disposal practices 
that were standard in the industry at the time, petroleum hydrocarbons or wastes may have been disposed of or released on or under 
the properties owned or leased by us or on or under other locations where such substances have been taken for disposal.  Such 
petroleum hydrocarbons or wastes may have migrated to property adjacent to our owned and leased sites or the disposal sites.  In 
addition, some of the properties may have been operated by third parties or by previous owners whose treatment and disposal or 
release of petroleum hydrocarbons or wastes was not under our control.  These properties and the substances disposed or released on 
them may be subject to CERCLA, RCRA and analogous state laws.  Under such laws, we could be required to remove previously 
disposed wastes, including waste disposed of by prior owners or operators; remediate contaminated property, including groundwater 
contamination, whether from prior owners or operators or other historic activities or spills; or perform remedial operations to prevent 
future contamination.  We are not currently a potentially responsible party in any federal or state Superfund site remediation and there 
are no current, pending or anticipated Superfund response or remedial activities at or implicating our facilities or operations. 

Water Discharges  

The Federal Water Pollution Control Act, also known as the Clean Water Act (the “CWA”), and comparable state laws 

impose restrictions and strict controls regarding the discharge of pollutants, including produced waters and other oil and natural gas 
wastes, into waters of the United States (“WOTUS”).  The discharge of pollutants into regulated waters is prohibited, except in 
accordance with the terms of a permit issued by the EPA or the state.  The discharge of dredge and fill material in regulated waters, 
including wetlands, is also prohibited, unless authorized by a permit issued by the U.S. Army Corps of Engineers (the “Corps”).  
These laws and any implementing regulations provide for administrative, civil and criminal penalties for any unauthorized discharges 
of oil and other substances in reportable quantities and may impose substantial potential liability for the costs of removal, remediation 

9 

Table of Contents  
and damages.  The scope of regulated waters has been subject to substantial controversy and uncertainty, with the Corps and EPA 
pursuing several rulemakings since 2015 to attempt to define the scope of WOTUS.  In September 2023, the EPA issued a WOTUS 
rule that is currently only implemented in 24 states due to ongoing litigation.  However, in November 2025, the EPA and the Corps 
proposed a rule to further update and narrow the September 2023 definition of WOTUS, guided by the Sackett v. EPA decision.  To 
the extent any judicial ruling, administrative rulemaking, or other action further changes the scope of the CWA’s jurisdiction in areas 
where we operate, we could face increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland 
areas.  Separately, we rely on the Corps’ CWA Section 404 Nationwide Permit (“NWP”) 12.  The NWP process relies upon the CWA 
Section 401 certification process.  In September 2023, the EPA published a rule finalizing its CWA Section 401 Water Quality 
Certification Improvement Rule, effective November 2023, but shortly thereafter, several states challenged the rule.  Litigation is 
ongoing.  In January 2026, the EPA published a proposed rule revising its regulations governing Water Quality Certifications.  While 
the full extent and impact of these actions is unclear at this time, any disruption in our ability to obtain coverage under NWP 12 or 
other general permits may result in increased costs and project delays if we are forced to seek individual permits from the Corps.  
However, we cannot predict what, when, or how the Trump administration may take action with respect to any of these regulations.  
As a result, there is significant uncertainty with respect to wetlands regulations under the CWA at this time. 

Pursuant to these laws and regulations, we may be required to obtain and maintain approvals or permits for the discharge of 

wastewater or storm water and are required to develop and implement spill prevention, control and countermeasure plans, also referred 
to as “SPCC plans,” in connection with on-site storage of significant quantities of oil.  These laws and regulations provide for 
administrative, civil and criminal penalties for any discharges not authorized by the permit and may impose substantial potential 
liability for the costs of removal, remediation and damages. 

Occupational Safety and Health Act  

We are also subject to the requirements of the federal Occupational Safety and Health Act, as amended (“OSHA”), and 

comparable state laws that regulate the protection of the health and safety of employees.  In addition, OSHA’s hazard communication 
standard, the Emergency Planning and Community Right to Know Act and implementing regulations and similar state statutes and 
regulations require that information be maintained about hazardous materials used or produced in our operations and that this 
information be provided to employees, state and local government authorities and citizens. 

Endangered Species  

The federal Endangered Species Act (“ESA”), provides for the protection of endangered and threatened species.  Pursuant to 
the ESA, if a species is listed as threatened or endangered, restrictions may be imposed on activities adversely affecting that species’ 
habitat.  Similar protections are offered to migratory birds under the Migratory Bird Treaty Act.  We conduct operations and have 
pipeline construction and maintenance projects in areas where certain species that are listed as threatened or endangered are known to 
exist and where other species that potentially could be listed as threatened or endangered under the ESA may exist.  The U.S. Fish and 
Wildlife Service (the “USFWS”), may designate critical habitat and suitable habitat areas that it believes are necessary for survival of 
a threatened or endangered species.  A critical habitat or suitable habitat designation could result in further material restrictions to 
federal land use and may materially delay or prohibit access to protected areas for natural gas and oil development.  Moreover, as a 
result of a settlement, the USFWS was required to make a determination as to whether more than 250 species classified as endangered 
or threatened should be listed under the ESA by the completion of the agency’s 2017 fiscal year.  For example, in April 2015, the 
USFWS listed the northern long-eared bat, whose habitat includes the areas in which we operate, as a threatened species under the 
ESA; however, following a 2020 court order to reconsider this decision the USFWS redesignated this species as endangered in 
November 2022, which became effective March 1, 2023.  The designation of previously unprotected species as threatened or 
endangered, or redesignation of a threatened species as endangered, in areas where we conduct operations could cause us to incur 
increased costs arising from species protection measures or could result in limitations on our pipeline construction activities or the 
exploration and production activities of Antero Resources, any of which could have an adverse impact on our results of operations. 

Air Emissions  

The federal Clean Air Act (“CAA”), and comparable state laws, regulate emissions of air pollutants from various industrial 
sources, including natural gas processing plants and compressor stations, and also impose various emission limits, operational limits 
and monitoring, reporting and recordkeeping requirements on air emission sources.  Failure to comply with these requirements could 
result in monetary penalties, injunctions, conditions or restrictions on operations and potentially criminal enforcement actions.  These 
laws are frequently subject to change.  In 2020, the Trump administration maintained the National Ambient Air Quality Standard 
(“NAAQS”) for ozone at 70 parts per billion for both the eight-hour primary and secondary standards.  We cannot predict what further 
actions, if any, and on what timeline, the Trump administration may take with respect to these regulations.  Several EPA new source 
performance standards (“NSPS”), and national emission standards for hazardous air pollutants (“NESHAP”), also apply to our 
facilities and operations.  These NSPS and NESHAP standards impose emission limits and operational limits as well as detailed 

10 

Table of Contents  
testing, recordkeeping and reporting requirements on the “affected facilities” covered by these regulations.  Several of our facilities are 
“major” facilities requiring Title V operating permits which impose semi-annual reporting requirements.  However, the EPA has 
recently announced plans to reconsider many of these rules under the Trump administration’s deregulatory agenda and has, in the 
meantime, extended various compliance deadlines. 

Regulation of “Greenhouse Gas” Emissions 

The EPA under previous presidential administrations has adopted regulations under existing provisions of the CAA that, 

among other things, establish Prevention of Significant Deterioration (“PSD”), pre-construction permits, and Title V operating permits 
for GHG emissions from certain large stationary sources that are already potential major sources of criteria pollutant emissions 
regulated under the statute.  Under these regulations, facilities required to obtain PSD permits must meet “best available control 
technology” standards for their GHG emissions established by the states or, in some cases, by the EPA, for those emissions.  The EPA 
has also adopted rules requiring the monitoring and reporting of GHG emissions from specified sources in the United States, 
including, among others, certain onshore oil and natural gas processing and fractionating facilities.  Although the EPA has proposed to 
delay GHG reporting for the oil and gas sector until 2034, and to otherwise repeal GHG reporting requirements for other sectors, we 
cannot predict whether these efforts will ultimately be successful or that GHG reporting will not be required again in the future.  
Existing climate change-related regulation has already become a focus of the Trump administration.  President Trump has signed 
several Executive Orders rescinding many of the previous administration’s Executive Orders and associated climate-related initiatives.  
President Trump’s directives included, amongst others, directing the EPA to reconsider its 2009 endangerment findings relating to 
GHGs, which provides regulatory justification for federal GHG permitting and methane emission control requirements, and directing 
the EPA to reconsider its use of Social Cost of GHG estimates in federal permitting decisions.  To that end, in March 2025, the EPA 
announced formal reconsideration of both the Social Cost of GHG estimates and the 2009 endangerment finding and, in July 2025, 
released a proposal to rescind the latter.  We cannot predict the ultimate impact of these actions or any similar future changes on our 
business or results of operations. 

The federal regulation of methane from oil and gas facilities has been subject to substantial uncertainty in recent years.  In 

December 2023, the EPA finalized more stringent methane rules for new, modified, and reconstructed facilities, known as OOOOb, as 
well as standards for existing sources for the first time ever, known as OOOOc.  However, in March 2025, the EPA announced plans 
to reconsider OOOOb and OOOOc, in line with the Trump administration’s deregulatory agenda.  Additionally, in November 2025, 
the EPA finalized an interim rule extending the compliance deadlines for certain provisions provided in OOOOb and OOOOc.  
Litigation challenging the EPA’s final interim rule extending such compliance deadlines for new and existing oil and gas source 
remains pending. 

In August 2022, the IRA 2022 was signed into law, which appropriated significant federal funding for renewable energy 

initiatives and imposed a federal fee on excess methane emissions from certain oil and gas facilities.  On November 12, 2024, the EPA 
finalized a rule requiring oil and gas facilities that emit more than 25,000 metric tons of CO2 per year to pay a set fee per metric ton of 
methane emissions that exceed statutory thresholds.  However, in February 2025, Congress repealed the rule under the Congressional 
Review Act.  Additionally, under the One Big Beautiful Bill Act (the “OBBB”), Congress delayed the implementation of the methane 
emissions fee until 2034.  Compliance with the methane emissions fee and other air pollution control and permitting requirements 
could increase our operating costs and accelerate the transition away from oil and natural gas, which could in turn adversely affect our 
business and results of operations, as well as those of our customers.  Moreover, failure to comply with these CAA requirements can 
result in the imposition of substantial fines and penalties as well as costly injunctive relief.  Given that the long-term trend toward 
increasing regulation, future federal GHG regulations of the oil and gas industry remain a possibility, and several states have 
separately imposed their own regulations on methane emissions from oil and gas production activities.  To the extent not timely 
repealed or modified by the Trump administration, these rules could impose new compliance costs and permitting burdens on natural 
gas operations.  We cannot predict when or whether the administration may take further actions, or the resulting impact on our 
business operations. 

Since 2017, we have published an annual ESG report, which highlights our most significant environmental program 
improvements and initiatives.  As highlighted in this report, our methane leak loss rate in 2024 was 0.033%, which was calculated in 
accordance with OneFuture, a voluntary industry partnership focused on reducing methane emissions from the natural gas sector, well 
below the OneFuture voluntary industry target of 1%. 

11 

Table of Contents  
During 2025, our GHG/methane emission reduction efforts included the following activities: 

•  Conducted quarterly facility LDAR inspections on all of our compressor stations. 

• 

Installed pigging blowdown capture systems at one compressor station and one pipeline interchange. 

•  Continued implementation of a double-pig capture process that reduces the frequency of pig receiver blowdowns, 

which has the effect of reducing emissions and improving labor efficiency. 

•  Continued deployment of a technology that was successfully field pilot tested with a major engine manufacturer to 
reduce total carbon emissions while increasing the efficiency of the engine by adding additional horsepower. 

•  Continued to shepherd patent pending technology that passed proof of concept examination for hydraulic emission 

displacement designed to eliminate GHG emissions from pipeline maintenance activities. 

•  Utilized our ESG Advisory Council together with our GHG/Methane Reduction Team to manage the identification, 

evaluation, monitoring, mitigation and adaptation, as applicable, of risks and opportunities related to the 
environment. 

•  Maintained our marginal abatement cost curve (“MACC”) to effectively and systematically model emission 

reduction projects across our operations.  Our MACC process is instrumental in evaluating the capital improvements 
required to achieve our emissions goals. 

We continue to assess various opportunities for emission reductions.  However, we cannot guarantee that we will be able to 
implement any of the opportunities that we may review or explore.  For any such opportunities that we do choose to implement, we 
cannot guarantee that we will be able to implement them within a specific timeframe or across all operational assets, or their ultimate 
effectiveness.  We did not have any material capital or other non-recurring expenditures in complying with environmental laws or 
environmental remediation matters in 2025.  However, we cannot guarantee that we will not incur material costs related to compliance 
with or liability under environmental laws and regulations in the future.  For risks and uncertainties related to sustainability matters, 
see “Item 1A. Risk Factors—Business Operations—Sustainability matters and conservation measures may adversely impact our 
business.” 

Increasingly, oil and natural gas companies are exposed to litigation risks related to climate risks.  While we are not currently 
party to any such litigation, we could be named in future actions making similar claims of liability and depending on the nature of the 
claims asserted and other factors, such liability could be imposed without regard to the company’s causation of or contribution to the 
asserted damage, or to other mitigating factors.  Additionally, demand for hydrocarbons, and therefore our products and services, may 
be reduced by actions taken at the federal, state or local levels to restrict, ban or limit products that rely on oil and natural gas. 

Additionally, our access to capital may be impacted by climate risk policies.  Financial institutions may adopt policies that 

have the effect of reducing the funding provided to the oil and natural gas industry, although this trend has generally been decreasing.  
To the extent implemented or pursued, such policies and commitments could lead to some lenders restricting access to capital for or 
divesting from certain industries or companies, including the oil and natural gas sector, or requiring that borrowers take additional 
steps to reduce their GHG emissions.  While we cannot predict how or to what extent sustainable lending and investment practices 
may impact our operations, a material reduction in the capital available to the oil and natural gas industry could make it more difficult 
to secure funding for exploration, development, production, transportation and processing activities, which could result in decreased 
demand for our midstream services. 

In addition, some states have adopted or are considering adopting laws requiring the disclosure of climate-related risks.  

Lawsuits have been filed challenging the implementation of these laws, but we cannot predict the outcome of these suits at this time.  
Compliance with these laws, to the extent implemented and applicable to us, may result in additional costs related to disclosure 
requirements as well as increased costs of and restrictions on access to capital.  Separately, enhanced climate-related disclosure 
requirements could lead to reputational or other harm, and could also increase our litigation risks relating to statements alleged to have 
been made by us or others in our industry regarding climate risks, or in connection with any future disclosures we may make regarding 
reported emissions, particularly given the inherent uncertainties and estimations with respect to calculating and reporting GHG 
emissions. 

Moreover, climate risks may also result in various physical risks such as the increased frequency or intensity of extreme 

weather events or changes in meteorological and hydrological patterns that could adversely impact our financial condition and 
operations, as well as those of our suppliers or customers.  Such physical risks may result in damage to our facilities or otherwise 
adversely impact our operations, such as if we become subject to water use curtailments in response to drought, or demand for our 

12 

Table of Contents  
services, such as to the extent warmer winters reduce the demand for energy for heating purposes.  Such physical risks may also 
impact the infrastructure on which we rely to provide our services.  One or more of these developments could have a material adverse 
effect on our business, financial condition and operations. 

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.  See “Item 3. Legal 
Proceedings.” 

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. 

Human Capital 

We believe that our employees and contractors are significant contributors to our past and future success, which depends on 

our ability to attract, retain and motivate qualified personnel.  The skills, experience and industry knowledge of key employees 
significantly benefit our operations and performance. 

All of our executive officers and other personnel who provide corporate, general and administrative services to our business 

are, when providing services to us, concurrently employed by Antero Resources and us pursuant to the terms of a services agreement.  
In addition, our operational personnel are seconded to us by Antero Resources pursuant to the terms of a secondment agreement and 
individuals are concurrently employed by Antero Resources and us during such secondment.  As of December 31, 2025, 632 people 
were concurrently employed by us and Antero Resources pursuant to these arrangements.  We and Antero Resources consider our 
relations with these employees to be generally good. 

Total Rewards 

We  have  demonstrated  a  history  of  investing  in  our  workforce  by  offering  competitive  salaries,  fair  living  wages  and 
comprehensive benefits.  To foster a stronger sense of ownership and align the interests of our personnel with shareholders, we provide 
long-term incentive programs that include restricted stock units, performance share units and cash awards.  Additionally, we offer short-
term cash incentive programs, which are discretionary and are based on individual and company performance factors, among others.  
Furthermore, we offer comprehensive benefits to our full-time employees working 30 hours or more per week.  To be an employer of 
choice and maintain the strength of our workforce, we consistently assess the current business environment and labor market to refine 
our compensation and benefits programs and other resources available to our personnel.  Among other benefits, these include:  

• 

• 

• 

• 

• 

• 

comprehensive health insurance, including vision and dental; we have not increased employee premiums in over 18 years; 

employee Health Savings Accounts, including contributions to these accounts by us; 

401(k) retirement savings plan with discretionary contribution matching opportunities; 

competitive paid time off and sick leave programs; 

paid parental leave; 

student loan repayment matching opportunities; and 

•  wellness support benefits including an employee assistance program, short-term and long-term disability coverage and 

gym membership and/or fitness subscription reimbursement, among others. 

Role Based Support 

We support our employees’ professional development.  To help our personnel succeed in their roles, we emphasize 
continuous formal and informal training, developmental and educational opportunities.  We also assist employees with the cost of such 
educational pursuits through our student loan repayment matching program.  Additionally, we have a robust performance evaluation 
program, which includes tools to facilitate goals and career progression.

Workforce Health and Safety 

The safety of our employees is a core tenet of our values, and our safety goal is zero incidents and zero injuries.  A strong 
safety culture reduces risk, enhances productivity and builds a strong reputation in the communities in which we operate.  We have 
earned a reputation as a safe and an environmentally responsible operator through continuous improvement in our safety performance.  
This makes us more attractive to current and new employees. 

We invest in safety training and coaching, promote risk assessments and encourage visible safety leadership.  Employees are 

empowered and expected to stop or refuse to perform a job if it is not safe or cannot be performed safely.  We sponsor emergency 
preparedness programs, conduct regular audits to assess our performance and celebrate our successes through the annual contractor 
safety conference where we acknowledge employees and contractors alike who have exhibited strong safety leadership during the 
course of the year.  These many efforts combine to create a culture of safety throughout the company and provide a positive influence 
on our contractor community. 

Equal Employment Opportunity and Workplace Culture  

We are committed to building a culture where equal employment opportunity and a strong workplace culture are core 

philosophies across our operations.  We prohibit all forms of unlawful discrimination and are committed to making opportunities for 
development and progress available to all employees so their talents can be fully developed to maximize our and their success.  We 
believe that creating an environment that cultivates a sense of belonging requires encouraging employees to continue to educate 
themselves about each other’s experiences, and we strive to promote the respect and dignity of all persons.  We also believe it is 
important that we foster education, communication and understanding about diverse backgrounds and perspectives as well as 
belonging.  Finally, in line with these beliefs and our commitment to equal employment opportunity, we expect recruiters operating on 
our behalf to provide us with a diverse pool of candidates.

ITEM 1A.  RISK FACTORS 

We are subject to certain risks and hazards due to the nature of the business activities we conduct.  The risks described in this 

Annual Report on Form 10-K could materially and adversely affect our business, financial condition, cash flows and results of 
operations.  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 our business, 
financial condition, cash flows and results of operations. 

Customer Concentration 

Because substantially all of our revenue is currently derived from Antero Resources, any development that materially and 
adversely affects Antero Resources’ operations, financial condition or market reputation could have a material and adverse 
impact on us. 

Antero Resources is our most significant customer and has accounted for substantially all of our revenue since inception, and 

we expect to derive most of our revenues from Antero Resources in the near term.  As a result, any event, whether in our area of 
operations or otherwise, that adversely affects Antero Resources’ production, drilling and completion schedule, financial condition, 
leverage, market reputation, liquidity, results of operations or cash flows may adversely affect our business and results of operations.  

14 

Table of Contents  
Accordingly, we are indirectly subject to the business risks of Antero Resources, including, among others: 

• 

• 

• 

a reduction in or slowing of Antero Resources’ development program, which would directly and adversely impact 
demand for our gathering and compression services and our water handling services; 

the volatility of natural gas, NGLs and oil prices, which could have a negative effect on the value of Antero Resources’ 
properties, its development program and its ability to finance its operations; 

the availability of capital on an economic basis to fund Antero Resources’ exploration and development activities and to 
service and/or refinance its debt, as well as to fund its capital expenditure programs; 

•  Antero Resources’ ability to replace its oil and gas reserves; 

•  Antero Resources’ drilling and operating risks, including potential environmental liabilities; 

• 

• 

transportation and processing capacity constraints and interruptions; and 

adverse effects of governmental and environmental regulation. 

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 deteriorate, nor can we estimate the impact such conditions would 
have on Antero Resources’ ability to execute its drilling and development program or perform under our gathering and compression 
and water handling services agreements.  Low commodity price environments can negatively impact natural gas producers and cause 
the industry significant economic stress, including, in certain cases, to file for bankruptcy protection or to renegotiate contracts.  To 
the extent that any customer, including Antero Resources, is in financial distress or commences bankruptcy proceedings, contracts 
with these customers may be subject to renegotiation or rejection under applicable provisions of the United States Bankruptcy Code.  
Any material non-payment or non-performance by Antero Resources could adversely affect our business and operating results. 

Also, due to our relationship with Antero Resources, our ability to access the capital markets, or the pricing or other terms of 

any capital markets transactions, may be adversely affected by any impairment to Antero Resources’ financial condition or adverse 
changes in its credit ratings. 

Any material limitation of our ability to access capital could limit our ability to obtain future financing under favorable terms, 

or at all, or could result in increased financing costs in the future.  Similarly, material adverse changes at Antero Resources could 
negatively impact our share price, limiting our ability to raise capital through equity issuances or debt financing, or could negatively 
affect our ability to engage in, expand or pursue our business activities and prevent us from engaging in certain transactions that might 
otherwise be considered beneficial to us. 

See Item 1A, “Risk Factors” in Antero Resources’ Annual Report on Form 10-K for the year ended December 31, 2025 

(which is not, and shall not be deemed to be, incorporated by reference herein) for a full disclosure of the risks associated with Antero 
Resources’ business. 

Because of the natural decline in production from existing wells, our success depends, in part, on Antero Resources’ ability to 
replace declining production and our ability to secure new sources of natural gas from Antero Resources or third parties.  
Additionally, our water handling services are directly associated with Antero Resources’ well completion activities and water 
needs, which are largely driven by the amount of water used in completing each well.  Finally, under certain circumstances, 
Antero Resources may dispose of acreage dedicated to us free from such dedication without our consent.  Any decrease in 
volumes of natural gas that Antero Resources produces, any decrease in the number of wells that Antero Resources completes, 
or any decrease in the number of acres that are dedicated to us could adversely affect our business and operating results. 

The natural gas volumes that support our gathering business depend on the level of production from wells connected to our 

systems, which may be less than expected and will naturally decline over time.  To the extent Antero Resources reduces its 
development activity or otherwise ceases to drill and complete new wells, revenues for our gathering and compression and water 
handling services will be directly and adversely affected.  Our ability to maintain water handling services revenues is substantially 
dependent on continued completion activity by Antero Resources or third parties over time, as well as the volumes of water used in 
and produced from such activity.  In addition, natural gas volumes from completed wells will naturally decline and our cash flows 
associated with these wells will also decline over time.  To maintain or increase throughput levels on our gathering systems, we must 
obtain new sources of natural gas from Antero Resources or third parties.  The primary factors affecting our ability to obtain additional 

15 

Table of Contents  
sources of natural gas include (i) the success of Antero Resources’ drilling activity in our areas of operation, (ii) Antero Resources’ 
ability to replace declining production, (iii) Antero Resources’ acquisition of additional acreage, including acquisitions that offset any 
dispositions by Antero Resources and (iv) our ability to obtain dedications of acreage from third parties.  Demand for our fresh water 
delivery services, which make up a substantial portion of our water handling services revenues, is dependent on water used in Antero 
Resources’ completion activities.  To the extent that Antero Resources or other fresh water delivery customers reduce the number of 
completion stages per well or use less water in their completions, the demand for our fresh water delivery services would be reduced. 

We have no control over Antero Resources’ or other producers’ levels of development and completion activity in our areas of 

operation, the amount of oil and gas reserves associated with wells connected to our systems or the rate at which production from a 
well declines.  In addition, our water handling business is dependent upon active development in our areas of operation.  To maintain 
or increase throughput levels on our water handling systems, we must service new wells.  We have no control over Antero Resources 
or other producers or their development plan decisions, which are affected by, among other things: 

• 

• 

• 

• 

• 

• 

• 

the availability and cost of capital; 

prevailing and projected natural gas, NGLs and oil prices; 

demand for natural gas, NGLs and oil; 

quantities of reserves; 

geologic considerations; 

environmental or other governmental regulations, including the availability of drilling permits and the regulation of 
hydraulic fracturing; and 

the costs of producing the gas and the availability and costs of drilling rigs and other equipment. 

The first of month prices for NYMEX Henry Hub natural gas ranged from a high of $4.42 per MMBtu to a low of $2.84 per 
MMBtu in 2025, and the calendar month average prices for NYMEX West Texas Intermediate crude oil ranged from a high of $75.10 
per barrel to a low of $57.87 per barrel during the same period.  Natural gas prices were substantially higher in 2025 than they were in 
2024, while oil prices decreased substantially in 2025 as compared to 2024.  The markets for these commodities have historically been 
volatile, and these markets will likely continue to be volatile in the future.  In addition, the market price for natural gas in the 
Appalachian Basin continues to be lower relative to NYMEX Henry Hub as a result of the significant increases in the supply of 
natural gas in the Appalachian region in recent years.  Because Antero Resources’ production and reserves predominantly consist of 
natural gas and NGLs (61% and 38% of equivalent proved reserves, respectively), changes in natural gas and NGLs prices have a 
significantly greater impact on Antero Resources’ financial results than oil prices.  NGLs are made up of ethane, propane, isobutane, 
normal butane and natural gasoline, all of which have different uses and different pricing characteristics, which adds further volatility 
to the pricing of NGLs.  Due to the volatility of commodity prices, we are unable to predict future potential movements in the market 
prices for natural gas, oil and NGLs at Antero Resources’ ultimate sales points and, thus, cannot predict the ultimate impact of prices 
on our operations. 

The industry shift towards maintenance capital development programs compelled most natural gas and oil producers, 
including Antero Resources, to reduce the level of exploration, drilling and production activity and capital budgets compared to prior 
years.  This shift had a significant effect on our capital resources, liquidity and expected operating results.  Natural gas and oil prices 
directly affect Antero Resources’ production.  If prices decrease from current levels, our revenues, cash flows and results of operations 
could continue to be adversely affected.  Sustained reductions in development or production activity in our areas of operation could 
lead to reduced utilization of our services and cash flows.  

Due to these and other factors, even if reserves are known to exist in areas served by our assets, producers have chosen and 

may choose in the future, not to develop those reserves.  Reductions in development activity, including Antero Resources’ reduction in 
lateral lengths or use of water in its completions, could result in our inability to maintain the current levels of throughput on our 
systems or reduce the demand for our water handling services on a per well basis, which could in turn reduce our revenue and cash 
flows and adversely affect our ability to return capital to our stockholders through dividends and/or repurchases of shares of our 
common stock. 

Finally, the 2019 gathering and compression agreement, Marcellus gathering and compression agreement, water services 
agreement and right-of-first-offer agreement between us and Antero Resources permits Antero Resources to sell, transfer, convey, 
assign, grant or otherwise dispose of dedicated properties free of the dedication under such agreements, provided that the number of 

16 

Table of Contents  
 
 
net acres of dedicated properties so disposed of, when added to the number of net acres of dedicated properties previously disposed of 
free of the dedication since the respective effective dates of the agreements, does not exceed the aggregate number of net acres of 
dedicated properties acquired by Antero Resources since such effective dates.  Accordingly, under certain circumstances, Antero 
Resources may dispose of a significant number of net acres of dedicated properties free from dedication without our consent, and we 
have no control over the timing or extent of such dispositions.  Any such dispositions could adversely affect our business and 
operating results.  Even if the disposed property remains dedicated to us, the goals and intention of the acquiror with respect to such 
property may differ significantly from those of Antero Resources.  For example, a subsequent owner of a property could choose to 
invest less capital in the development of such property or to otherwise drill fewer wells than Antero Resources.  There can be no 
assurance that a subsequent owner of dedicated properties would choose to, or be able to, grow or maintain current rates of production 
from the properties, which could adversely impact us. 

Business Operations 

A material shut-in of production by Antero Resources or any of our other customers could adversely affect our business. 

The marketing of the natural gas, NGLs and oil of our producer customers is substantially dependent upon the existence of 
adequate markets for their products.  Imbalances between the supply of and demand for these products could cause extreme market 
volatility and a substantial adverse effect on commodity prices.  For example, in response to the coronavirus pandemic, governments 
tried to slow the spread of the virus by imposing social distancing guidelines, travel restrictions and stay-at-home orders, which caused 
a significant decrease in the demand for oil, natural gas and NGLs.  Also, a supply and demand imbalance for oil, natural gas and 
NGLs in the future could result in storage capacity constraints.  During times of supply and demand imbalance, if Antero Resources or 
any of our other customers are unable to sell their production or enter into additional storage arrangements on commercially 
reasonable terms or at all, they may be forced to temporarily shut-in a portion of their production or delay or discontinue drilling and 
completion plans and commercial production.  Although Antero Resources has not been required to temporarily shut-in a portion of its 
production due to storage capacity constraints, it may do so in the future.  Production curtailments or shut-ins by our producer 
customers will reduce volumes flowing through our gathering and processing system.  In addition, if our customers delay or 
discontinue drilling or completion activities, it will reduce the volumes of water that we handle.  A material reduction in volumes on 
our systems could adversely affect our business, revenue and cash flows and could adversely affect our ability to return capital to our 
stockholders through dividends and/or repurchases of shares of AM common stock. 

Our gathering and compression agreements include minimum volume commitments only under certain circumstances. 

Our gathering and compression agreements include minimum volume commitments only on new high pressure pipelines 

and/or compressor stations, as applicable, constructed at Antero Resources’ request.  There are no minimum volume commitments on 
the low pressure pipelines or fresh water delivery pipelines.  Any decrease in the current levels of throughput on our gathering, 
compression and fresh water delivery systems could reduce our revenue and cash flows. 

Our construction or purchase of new gathering and compression, processing, water handling or other assets may not be 
completed on schedule, at the budgeted cost or at all, may not operate as designed or at the expected levels, may not result in 
revenue increases and may be subject to regulatory, environmental, political, legal and economic risks, all of which could 
adversely affect our financial condition, cash flows and results of operations. 

The construction of additions or modifications to our existing systems and the construction or purchase of new assets 
involves numerous regulatory, environmental, political and legal uncertainties beyond our control and may require the expenditure of 
significant amounts of capital.  Financing may not be available on economically acceptable terms or at all.  If we undertake these 
projects, we may not be able to complete them on schedule, at the budgeted cost or at all, or they may not operate as designed or at the 
expected levels.  Moreover, our revenues may not increase immediately upon the expenditure of funds on a particular project.  In 
addition, we may construct facilities to capture anticipated future production growth in an area in which such growth does not 
materialize.  As a result, new gathering and compression, water handling or other assets may not be able to attract enough throughput 
to achieve our expected investment return, which could adversely affect our financial condition and results of operations.  
Furthermore, adding to our existing assets may require us to obtain new rights-of-way prior to constructing new pipelines or facilities.  
We may be unable to timely obtain such rights-of-way to connect new natural gas supplies to our existing gathering pipelines or 
capitalize on other attractive expansion opportunities.  Additionally, it may become more expensive for us to obtain new rights-of-way 
or to expand or renew existing rights-of-way.  If the cost of renewing or obtaining new rights-of-way increases, our cash flows could 
be adversely affected. 

17 

Table of Contents  
Recent action and the possibility of future action on trade by U.S. and foreign governments has increased the costs of certain 
equipment and materials used in the construction of our assets and has created uncertainty in global markets, which may 
adversely affect our income from operations and cash flows. 

The construction of gathering pipelines, compressor stations, processing and fractionation facilities and water handling assets 
is subject to construction cost overruns due to costs and availability of equipment and materials such as steel.  If third-party providers 
of steel products essential to our capital improvements and additions are unable to obtain raw materials, including steel, at historical 
prices, they may raise the price we pay for such products. 

Price increases for materials used in the construction of our assets, including as a result of tariffs, supply chain disruptions, or 

inflation of prices for commodities, materials, products and shipping, may result in increased costs associated with the continued 
build-out of our assets, as well as projects under development.  Because we generate substantially all of our revenue under agreements 
with Antero Resources that provide for fixed fee structures, we will generally be unable to pass these cost increases along to our 
customers, and our income from operations and cash flows may be adversely affected. 

If third-party pipelines or other midstream facilities interconnected to our gathering and compression systems become 
partially or fully unavailable, our operating margin and cash flows could be adversely affected. 

Our gathering and compression assets connect to other pipelines or facilities owned and operated by unaffiliated third parties.  

The continuing operation of third-party pipelines, compressor stations and other midstream facilities is not within our control.  These 
pipelines, plants and other midstream facilities may become unavailable because of testing, turnarounds, line repair, maintenance, 
reduced operating pressure, lack of operating capacity, regulatory requirements and curtailments of receipt or deliveries due to 
insufficient capacity or because of damage from severe weather conditions or other operational issues.  If any such increase in costs 
occurs or if any of these pipelines or other midstream facilities become unable to receive or transport natural gas, our operating margin 
and cash flows could be adversely affected. 

Our exposure to commodity price risk may change over time. 

We currently generate all of our revenues pursuant to fee-based contracts under which we are paid based on the volumes of 

natural gas that we gather, process and compress and water that we handle and treat, rather than the underlying value of the 
commodity.  Consequently, our existing operations and cash flows have little direct exposure to commodity price risk.  Although we 
intend to enter into similar fee-based contracts with new customers in the future, our efforts to negotiate such contractual terms may 
not be successful.  In addition, we may acquire or develop additional midstream assets in a manner that increases our exposure to 
commodity price risk.  Future exposure to the volatility of natural gas, NGLs and oil prices, especially in light of the recent declines, 
could have a material adverse effect on our business, financial condition and results of operations. 

The fees charged to our customers may not escalate sufficiently to cover increases in costs, or the agreements may be amended 
with less favorable terms, may not be renewed or may be suspended in some circumstances. 

As the rate of inflation has increased in the U.S., the cost of the goods and services and labor we use in our operations has 

also increased, increasing our operating costs.  Our costs may increase at a rate greater than the fees we charge to our customers.  
Furthermore, Antero Resources and our other customers may not renew their contracts with us, or may from time to time seek to 
renegotiate with us the amount and/or the structure of fees we charge.  Additionally, some of our customers’ obligations under their 
agreements with us may be permanently or temporarily reduced due to certain events, some of which are beyond our control, 
including force majeure events wherein the supply of natural gas, NGLs, crude oil or refined products are curtailed or cut-off due to 
events beyond our control, and in some cases, certain of those agreements may be terminated in their entirety if the duration of such 
events exceeds a specified period of time.  If the escalation of fees is insufficient to cover increased costs, our customers do not renew 
or extend their contracts with us, or our customers suspend or terminate their contracts with us, our financial results would suffer. 

Oil and natural gas producers’ operations, especially those using hydraulic fracturing, are substantially dependent on the 
availability of water. 

Our business includes fresh water delivery for use in our customers’ natural gas, NGLs and oil exploration and production 

activities.  Water is an essential component of natural gas, NGLs and oil production during the drilling, and in particular, the hydraulic 
fracturing process.  We derive a significant portion of our revenues from providing fresh water to Antero Resources.  Antero 
Resources implemented efficiency improvements and water initiatives during 2020, which reduced the amount of fresh water needed 
to complete their operations.  Furthermore, the availability of water supply for our operations may be limited due to, among other 
things, prolonged drought or state and local governmental authorities restricting the use of water for hydraulic fracturing.  The 
availability of water may also change over time in ways that we cannot control, including as a result of climate related effects such as 

18 

Table of Contents  
shifting meteorological and hydrological patterns.  Any decrease in the demand for water handling services, or the water supply we 
need to provide such services, would adversely affect our business and results of operations. 

Sustainability matters and conservation measures may adversely impact our business. 

Stakeholder attention to climate risks, societal expectations on companies related to climate risks, investor, regulatory, and 

societal expectations regarding voluntary and mandatory sustainability disclosures, and consumer demand for alternative forms of 
energy, may result in increased costs, reduced demand for our products, reduced profits, increased investigations and litigation and 
negative impacts on our stock price and access to capital markets.  Any increased attention to climate risks and environmental 
conservation, for example, may result in demand shifts for oil and natural gas products and additional governmental investigations and 
private litigation against us or our customers, including Antero Resources and, depending on the nature of the claims asserted and 
other factors, such liability could be imposed without regard to our causation of or contribution to the asserted damage, or to other 
mitigating factors.  While we may participate in various voluntary frameworks and certification programs to improve the ESG profile 
of our operations, we cannot guarantee that such participation or certification will have the intended results on our ESG profile.   

Moreover, while we create and publish voluntary disclosures regarding sustainability matters from time to time, many of the 
statements in those voluntary disclosures are based on expectations and assumptions or hypothetical scenarios that may or may not be 
representative of current or actual risks or events or forecasts of expected risks or events, including the costs associated therewith.  
Mandatory sustainability-related disclosure is also evolving as an area where we may be, or may become, subject to required 
disclosures in certain jurisdictions, depending on our purported nexus to such jurisdictions and any such mandatory disclosures may 
similarly necessitate the use of hypothetical, projected or estimated data, some of which is not controlled by us and is inherently 
subject to imprecision.  Disclosures reliant upon such expectations and assumptions or hypothetical scenarios are necessarily uncertain 
and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established approach to 
identifying, measuring and reporting on many sustainability matters.  In addition, while we may announce various voluntary 
sustainability targets, including certain GHG emissions goals, such targets are aspirational.  We may not be able to meet such targets 
in the manner or on such a timeline as initially contemplated, including, but not limited to as a result of unforeseen costs or technical 
difficulties associated with achieving such results.  To the extent we do meet such targets, it may be achieved through various 
contractual arrangements, including the purchase of various credits or offsets that may be deemed to mitigate our sustainability impact 
instead of actual changes in our sustainability performance.  However, given uncertainties related to the use of emerging technologies, 
the state of markets for and the availability of verified carbon offsets, we cannot predict whether or not we will be able to timely meet 
these goals, if at all.  A failure or a perception of failure (whether or not valid) to pursue or implement or adequately make progress 
toward such sustainability strategies or achieve such sustainability goals or commitments could result in private litigation and damage 
to our reputation.  In addition, while we may seek to purchase carbon offsets verified by reputable third parties, we cannot guarantee 
that any carbon offsets we purchase will achieve the GHG emission reductions represented, and we could face increased costs to 
purchase additional carbon offsets to cover any gap or loss, particularly if carbon offset markets face capacity constraints as a result of 
increased demand or heightened scrutiny of their methodologies.  Moreover, certain stakeholders may object to the use of offsets 
generally or with respect to specific transactions we engage in as to any carbon reduction benefits we may claim resulting from such 
offsets.  Furthermore, certain jurisdictions, including California, have instituted new laws that require disclosures related to voluntary 
carbon offsets and similar constructs.  Disclosures under these regimes are novel and it is uncertain whether any disclosures we may 
make in connection therewith will satisfy the laws and may lead to uncertain consequences, such as private parties criticizing such 
projects, whether via litigation or otherwise.  While we may participate in various voluntary frameworks and certification programs to 
improve the sustainability profile or transparency of our operations, we cannot guarantee that such participation or certification will 
have the intended results on our sustainability profile.  Also, despite these aspirational goals, we may receive pressure from investors, 
lenders or other groups to adopt more aggressive climate or other sustainability-related goals, but we cannot guarantee that we will be 
able to implement such goals in whole or in part because of potential costs or technical or operational obstacles.  

Furthermore, our reputation, as well as our stakeholder relationships, could be adversely impacted as a result of, among other 

things, any failure to meet our sustainability plans or goals or stakeholder perceptions of certain statements made by us, others in our 
industry, our employees and executives, agents, or other third parties or public pressure from investors or policy groups to change our 
policies.  Such statements with respect to sustainability matters are becoming increasingly subject to heightened scrutiny from public 
and governmental authorities, as well as other parties, related to the risk of potential “greenwashing,” i.e., misleading information or 
false claims overstating potential sustainability benefits.  Additionally, certain employment practices and social initiatives are the 
subject of scrutiny by both those calling of the continued advancement of such policies, as well as those who believe they should be 
curbed, including government actors, and the complex regulatory and legal frameworks applicable to such initiatives continue to 
evolve.  We cannot be certain of the impact of such regulatory, legal and other developments on our business.  More recent political 
developments could mean that we face increasing criticism or litigation risks from certain “anti-ESG” parties, including various 
governmental agencies.  Such sentiment may focus on our environmental commitments or our pursuit of certain employment practices 
or social initiatives that are alleged to be political or polarizing in nature or are alleged to violate laws based, in part, on changing 

19 

Table of Contents  
priorities of, or interpretations by, federal agencies or state governments.  Consideration of sustainability and social-related factors in 
our decision making could be subject to increasing scrutiny and objection from such anti-ESG parties.  As a result, we may face 
increased litigation risks from private parties and governmental authorities related to our sustainability efforts.  Moreover, any alleged 
claims of greenwashing against us or others in our industry may lead to negative sentiment towards our company or industry.  To the 
extent that the Company is unable to respond timely and appropriately to any negative publicity, our reputation could be harmed.  
Damage to our overall reputation could have a negative impact on our financial results and require additional resources for the 
Company to rebuild its reputation. 

In addition, organizations that provide information to investors on corporate governance and related matters have developed 

ratings and proxy voting recommendations processes for evaluating companies on their approach to sustainability matters.  Such 
ratings, proxy advisory services, and reports may be used by some investors to inform their investment and voting decisions.  While 
such ratings do not impact all investors’ investments or voting decisions, unfavorable sustainability ratings and recent activism 
directed at shifting funding away from companies with energy-related assets could lead to increased negative investor sentiment 
toward us, Antero Resources and our industry and to the diversion of investment to other industries, which could have a negative 
impact on our stock price and our access to and costs of capital.  Also, certain institutional lenders may decide not to provide funding 
for oil and natural gas companies or the corresponding infrastructure projects based on climate related concerns, which could affect 
our access to capital for potential growth projects.  Moreover, to the extent sustainability matters negatively impact our reputation, we 
may not be able to compete as effectively or recruit or retain employees, which may adversely affect our operations.  Such 
sustainability matters may also impact Antero Resources and our customers, which may adversely impact our business, financial 
condition or results of operations. 

Our business involves many hazards and operational risks, some of which may not be fully covered by insurance.  The 
occurrence of a significant accident or other event that is not fully insured could curtail our operations and have a material 
adverse effect on our business, financial condition and results of operations. 

Our operations are subject to all of the hazards associated with the processing, gathering and compression of natural gas, 

NGLs and oil and water handling services, including: 

• 

• 

• 

• 

• 

• 

• 

unintended breach of impoundment and downstream flooding, release of invasive species or aquatic pathogens, 
hazardous spills near intake points, trucking collision, vandalism, excessive road damage or bridge collapse and 
unauthorized access or use of automation controls; 

damage to pipelines, compressor stations, pumping stations, blending facilities, impoundments, related equipment and 
surrounding properties caused by natural disasters, acts of terrorism and acts of third parties; 

damage from construction, farm and utility equipment as well as other subsurface activity (for example, mine 
subsidence); 

leaks of natural gas, NGLs or oil or losses of natural gas, NGLs or oil as a result of the malfunction of equipment or 
facilities; 

fires, ruptures and explosions; 

other hazards that could also result in personal injury and loss of life, pollution of the environment, including natural 
resources and suspension of operations; and 

hazards experienced by other operators that may affect our operations by instigating increased regulations and oversight. 

Any of these risks could adversely affect our ability to conduct operations or result in substantial loss to us as a result of 

claims for: 

• 

• 

• 

• 

injury or loss of life; 

damage to and destruction of property, natural resources and equipment; 

pollution and other environmental damage; 

regulatory investigations and penalties; 

20 

Table of Contents  
• 

• 

suspension of our operations; and 

repair and remediation costs. 

We may elect not to obtain insurance for any or all of these risks if we believe that the cost of available insurance is excessive 

relative to the risks presented.  In addition, pollution and environmental risks generally are not fully insurable under policies we are 
covered under, and we have obtained pollution insurance.  The occurrence of an event that is not fully covered by insurance could 
have a material adverse effect on our business, financial condition and results of operations. 

An impairment of our assets, including property and equipment and/or intangible assets could reduce our earnings. 

GAAP requires us to test certain assets for impairment on either an annual basis or when events or circumstances occur 

which indicate that the carrying value of such assets might be impaired.  The outcome of such testing could result in impairments of 
our assets, including property and equipment and/or intangible assets.  Additionally, any asset monetizations could result in 
impairments if any assets are sold or otherwise exchanged for amounts less than their carrying value.  If we determine that an 
impairment has occurred, we would be required to take an immediate noncash charge to earnings.  During the year ended December 
31, 2025, we 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 in our consolidated statements of operations and comprehensive income. 

We do not own all of the land on which our pipelines and facilities are located, which could result in disruptions to our 
operations. 

Because we do not own all of the land on which our pipelines and facilities have been constructed, we are subject to the 
possibility of more onerous terms or increased costs to retain necessary land use if we do not have valid rights-of-way or if such 
rights-of-way lapse or terminate.  We obtain the rights to construct and operate our pipelines on land owned by third parties and 
governmental agencies for a specific period of time.  Our loss of these rights, through our inability to renew right-of-way contracts or 
otherwise, could have a material adverse effect on our business, financial condition and results of operations. 

World health events may materially adversely affect our business. 

World health events may cause disruptions to our business and operational plans, which may include (i) shortages of 

employees, (ii) unavailability of contractors and subcontractors, (iii) interruption of supplies from third parties upon which we rely, 
(iv) recommendations of, or restrictions imposed by, government and health authorities, including quarantines and (v) restrictions that 
we and our contractors and subcontractors impose, including facility shutdowns, to ensure the safety of employees and others.  While 
it is not possible to predict their extent or durations, these disruptions may have a material adverse effect on our business, financial 
condition and results of operations and could adversely affect our ability to return capital to our stockholders through dividends and/or 
repurchases of shares of AM common stock. 

Further, adverse impacts on Antero Resources’ business resulting from world health events may also adversely affect our 

business and results of operations.  The effects of a pandemic, epidemic or outbreak of an infectious disease and concerns regarding its 
global spread could negatively impact global demand for crude oil and natural gas, which may contribute to price volatility that could 
impact the price Antero Resources’ receives for its natural gas, NGLs and oil and materially and adversely affect the demand for and 
marketability of Antero Resources’ production, as well as lead to temporary curtailment or shut-ins of production due to lack of 
downstream demand or storage capacity.  For further discussion of the business risks of Antero Resources that may impact us, see “—
Customer Concentration—Because substantially all of our revenue is currently derived from Antero Resources, any development that 
materially and adversely affects Antero Resources’ operations, financial condition or market reputation could have a material and 
adverse impact on us.” 

Terrorist attacks, cyberattacks and threats could have a material adverse effect on our business, financial condition and 
results of operations. 

Terrorist attacks or cyberattacks may significantly affect the energy industry, including our operations and those of our 

suppliers and customers, as well as general economic conditions, consumer confidence and spending and market liquidity.  Cyber 
incidents, including deliberate attacks, have increased in frequency globally.  Strategic targets, such as energy related assets, may be at 
greater risk of future attacks than other targets in the United States.  We depend on digital technology in many areas of our business 
and operations, including, but not limited to, performing many of our gathering and compression and water handling services, 
processing and recording financial and operating data, oversight and analysis of our operations and communications with the 
employees supporting our operations and our customers or service providers.  We also collect and store sensitive data in the ordinary 
course of our business, including personally identifiable information as well as our proprietary business information and that of our 

21 

Table of Contents  
customers, suppliers, investors and other stakeholders.  The growing regulatory landscape around data protection adds additional 
complexity to safeguarding this information.  The secure processing, maintenance and transmission of information is critical to our 
operations, and we monitor our key information technology systems in an effort to detect and prevent cyberattacks, security breaches 
or unauthorized access.  Despite our security measures, our information technology systems may undergo cyberattacks or security 
breaches including as a result of employee error, malfeasance or other threat vectors, which could lead to the corruption, loss, or 
disclosure of proprietary and sensitive data, misdirected wire transfers, and an inability to: perform services for our customers; 
complete or settle transactions; maintain our books and records; prevent environmental damage; and maintain communications or 
operations.  Significant liability to the Company or third parties may result.  We are not able to anticipate, detect or prevent all 
cyberattacks, particularly because the methodologies used by attackers change frequently or may not be recognized until an attack is 
already underway or significantly thereafter, and because attackers are increasingly using technologies specifically designed to 
circumvent cybersecurity measures and avoid detection.  Cybersecurity attacks are also becoming more sophisticated and include, but 
are not limited to, ransomware, credential stuffing, spear phishing, social engineering, use of deepfakes (e.g., highly realistic synthetic 
media generated by artificial intelligence) and other attempts to gain unauthorized access to data for purposes of extortion or other 
malfeasance. 

Our information and operational technologies, systems and networks, and those of our vendors, suppliers, customers and 

other business partners, may become the target of cyberattacks or information security breaches that result in the unauthorized release, 
gathering, monitoring, misuse, loss or destruction of proprietary and other information, or adversely disrupt our business operations.  
The interconnected nature of our industry heightens the risk that a cybersecurity incident affecting one of our vendors, suppliers, 
customers or other business partners could propagate across the supply chain, potentially causing widespread operational or financial 
disruptions.  Although we have written policies and procedures for monitoring cybersecurity risk and identifying and reporting 
incidents, there can be no guarantee they will be effective at preventing cyberattacks or ensuring incidents are timely identified or 
reported.  Some cyber incidents, such as surveillance, ransomware, or deepfake-based social engineering attacks, may remain 
undetected for some period of time.  Advances in computer capabilities, discoveries in the field of artificial intelligence, cryptography, 
or other developments may result in a compromise or breach of the technology we use to safeguard confidential, personal or other 
information.  As cyberattacks continue to evolve, we may be required to expend significant additional resources to continue to modify 
or enhance our protective measures or to investigate and remediate any vulnerabilities to cyberattacks.  In particular, our 
implementation of various procedures and controls to monitor and mitigate security threats and to increase security for our personnel, 
information, facilities and infrastructure may result in increased capital and operating costs.  While we maintain cyber insurance 
coverage to help mitigate financial risks associated with cyber incidents, such policies have limitations and do not cover all potential 
losses, such as reputational harm or regulatory fines.  Accordingly, our cyber insurance may not provide coverage for all potential 
risks arising from cyber incidents.  As cyberattacks increase globally in frequency and severity, coverage availability and affordability 
may further decline.  A successful cyberattack or security breach could result in liability resulting from data privacy or cybersecurity 
claims, liability under data privacy laws, regulatory penalties, damage to our reputation, long-lasting loss of confidence in us, or 
additional costs for remediation and modification or enhancement of our information systems to prevent future occurrences, all of 
which could have a material and adverse effect on our business, financial condition or results of operations.  To date, we have not 
experienced any material losses relating to cyberattacks; however, there can be no assurance that we will not suffer such losses in the 
future.  No security measure is infallible.  Consequently, it is possible that any of these occurrences, or a combination of them, could 
have a material adverse effect on our business, financial condition and results of operations. 

Capital Structure and Access to Capital 

We may not be able to generate sufficient cash to service all of our indebtedness and may be forced to take other actions to 
satisfy our obligations under our indebtedness or to refinance, which may not be successful. 

Our ability to make scheduled payments on, or to refinance, our indebtedness obligations, including the Credit Facility and 

our senior notes, depends on our financial condition and operating performance, which are subject to prevailing economic and 
competitive conditions and certain financial, business and other factors beyond our control.  We may not be able to maintain a level of 
cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, 
including the Credit Facility and our senior notes. 

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or 

delay investments and capital expenditures, sell assets, seek additional capital or restructure or refinance our indebtedness, including 
the senior notes.  Our ability to restructure or refinance our indebtedness will depend on the condition of the credit and capital 
markets, including the markets for credit facilities and senior unsecured notes, and our financial condition at such time.  Any 
refinancing of our indebtedness, including using borrowings under the Credit Facility to redeem our senior notes, could be at higher 
interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations.  The 
terms of existing or future debt instruments, including the Credit Facility and the indentures governing our senior notes, may restrict 

22 

Table of Contents  
us from adopting some of these alternatives.  In addition, any failure to make payments of interest and principal on our outstanding 
indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional 
indebtedness and result in more onerous restrictions in our debt securities and facilities.  In the absence of sufficient cash flows and 
capital resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to 
meet our debt service and other obligations.  The Credit Facility and the indentures governing our senior notes place certain 
restrictions on our ability to dispose of assets and our use of the proceeds from such dispositions.  We may not be able to consummate 
those dispositions, and the proceeds of any such disposition may not be adequate to meet any debt service obligations then due.  These 
alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. 

We will be required to make capital expenditures to increase our asset base.  If we cannot obtain needed capital or financing 
on satisfactory terms, we may be unable to expand our business operations and/or our financial leverage could increase. 

To increase our asset base, we will need to make expansion capital expenditures.  If we do not make sufficient or effective 
expansion capital expenditures, we may be unable to expand our business operations, which could adversely affect our business and 
operating results.  To fund our expansion capital expenditures and investment capital expenditures, we expect to use cash from our 
operations or incur borrowings.  Alternatively, we may sell additional shares of common stock or other securities to fund our capital 
expenditures.  Our ability to obtain bank financing or our ability to access the capital markets for future equity or debt offerings may 
be limited by our or Antero Resources’ financial condition at the time of any such financing or offering and the covenants in our 
existing debt agreements, as well as by general economic conditions, contingencies and uncertainties that are beyond our control.  In 
addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing shares of 
common stock may result in significant stockholder dilution.  Neither Antero Resources or any of its affiliates is committed to 
providing any direct or indirect support to fund our growth. 

We may be unable to access the equity or debt capital markets to meet our obligations.   

Declines in commodity prices or the financial condition or prospects of Antero Resources may cause the financial markets to 

exert downward pressure on our stock price and credit capacity.  For example, for portions of 2020, the market for senior unsecured 
notes was unfavorable for high-yield issuers such as us.  Our plans for growth may require access to the capital and credit markets.  
Although the market for high-yield debt securities has improved since 2020, if the high-yield market deteriorates, or if we are unable 
to access alternative means of debt or equity financing on acceptable terms or at all, we may be unable to carry out our business plan, 
which could have a material adverse effect on our financial condition and results of operations and impair our ability to service our 
indebtedness. 

Restrictions in our existing and future debt agreements could adversely affect our business, financial condition and results of 
operations. 

The Credit Facility limits our ability to, among other things: 

• 

permit liens on our properties; 

•  make certain investments; 

•  merge, consolidate, liquidate or dissolve; 

• 

• 

• 

• 

dispose of assets; 

enter into certain types of transactions with affiliates; 

prepay or amend certain indebtedness; and 

enter into certain swap and hedging transactions. 

The indentures governing our senior notes contains similar restrictive covenants.  In addition, the Credit Facility contains 

covenants requiring us to maintain certain financial ratios.  Our ability to meet those financial ratios and tests can be affected by 
events beyond our control, and we cannot assure you that we will meet any such ratio or test.  Additionally, we may not be able to 
borrow the full amount of commitments under the Credit Facility if doing so would cause us to breach a financial covenant. 

The provisions of the Credit Facility and the indentures governing our senior notes may affect our ability to obtain future 

financing and pursue attractive business opportunities and our flexibility in planning for, and reacting to, changes in business 

23 

Table of Contents  
conditions.  In addition, a failure to comply with the provisions of the Credit Facility or the indentures governing our senior notes 
could result in a default or an event of default that would restrict our ability to access loans under our Credit Facility and could enable 
our lenders or noteholders to declare the outstanding principal of that debt, together with accrued and unpaid interest, to be 
immediately due and payable.  If our obligations to repay our debt are accelerated, our assets may be insufficient to repay such debt in 
full, and you could experience a partial or total loss of your investment.  See Note 9—Long-Term Debt to our consolidated financial 
statements for additional information. 

Debt we incur in the future may limit our flexibility to obtain financing and to pursue other business opportunities. 

Our future level of debt could have important consequences to us, including the following: 

• 

• 

our ability to obtain additional financing, if necessary, for working capital, capital expenditures (including required 
drilling pad connections and well connections pursuant to our gathering and compression agreements as well as 
acquisitions) or other purposes may be impaired or such financing may not be available on favorable terms; 

our funds available for operations and future business opportunities will be reduced by that portion of our cash flows 
required to make interest payments on our debt; 

•  we may be more vulnerable to competitive pressures or a downturn in our business or the economy generally; and 

• 

our flexibility in responding to changing business and economic conditions may be limited. 

Our ability to service our debt will depend upon, among other things, our future financial and operating performance, which 

will be affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond our 
control.  If our operating results are not sufficient to service any future indebtedness, we will be forced to take actions such as 
reducing or not paying dividends, reducing or delaying our business activities, investments or capital expenditures, selling assets or 
issuing equity.  We may not be able to effect any of these actions on satisfactory terms or at all. 

Increases in interest rates could adversely affect our business. 

Our business and operating results can be harmed by factors such as the availability, terms of and cost of capital, increases in 

interest rates or a reduction in credit rating.  These changes could cause our cost of doing business to increase, limit our ability to 
pursue growth opportunities, reduce cash flow used for our services and place us at a competitive disadvantage.  For example, during 
2025, we had average outstanding borrowings under the Credit Facility of $463 million, and the impact of a 1.0% increase in interest 
rates on this amount of indebtedness would result in increased interest expense for that period of $5 million and a corresponding 
decrease in our cash flows and net income before the effects of income taxes.  Disruptions and volatility in the global financial 
markets may lead to a contraction in credit availability impacting our ability to finance our operations.  A significant reduction in cash 
flows from operations or the availability of credit could materially and adversely affect our ability to carry out our business plan. 

Geographic Concentration 

Our gathering and compression and water handling systems are concentrated in the Appalachian Basin, making us vulnerable 
to risks associated with operating in one major geographic area. 

We rely primarily on revenues generated from our gathering and compression and water handling systems, which are all 

located in the Appalachian Basin.  As a result of this concentration, we may be disproportionately exposed to the impact of regional 
supply and demand factors, delays or interruptions of production from wells in this area caused by, and associated with, governmental 
regulation, state and local political activities, market limitations, availability of equipment and personnel or interruption of the 
compression, processing or transportation of natural gas, NGLs or oil. 

A shortage of equipment and skilled labor in the Appalachian Basin could reduce equipment availability and labor 
productivity and increase labor costs, which could have a material adverse effect on our business and results of operations. 

Gathering and compression and water handling services require special equipment and laborers skilled in multiple 

disciplines, such as equipment operators, mechanics and engineers, among others.  If Antero Resources experiences shortages of 
skilled labor or there is a lack of necessary equipment in the Appalachian Basin in the future, our allocation of labor costs and overall 
productivity could be materially and adversely affected.  If our allocation of labor prices increase or if Antero Resources experiences 
materially increased health and benefit costs for employees, our business and results of operations could be materially and adversely 
affected.

Acquisitions and Divestitures 

We may not achieve the intended benefits of the HG Acquisition, and the HG Acquisition may disrupt our existing plans or 
operations. 

There can be no guarantee that we will be able to successfully integrate the assets and operations to be acquired in, or 

otherwise realize the expected benefits of, the HG Acquisition.  Difficulties in integrating the assets acquired in the HG Acquisition 
may result in operational and other challenges, including the diversion of management’s attention from ongoing business concerns; the 
diversion of resources to integration processes; the retention of existing business and operational relationships, including customers, 
suppliers and other counterparties; the attraction of new business and operational relationships; the possibility of faulty assumptions 
underlying expectations regarding integration processes and associated expenses; the elimination of duplicative corporate or 
operational processes; as well as unanticipated issues in integrating certain systems, including internal controls over financial 
reporting and disclosure controls and procedures.  An inability to realize the full extent of the intended benefits of the HG Acquisition, 
and any delays encountered in the integration process, could have an adverse effect on our revenues and level of expenses and results 
of operations.  In addition, the integration may result in additional or unforeseen expenses.  Although we expect the strategic benefits 
to offset incremental transaction-related costs over time, if we are not able to adequately and effectively address integration 
challenges, we may be unable to successfully integrate operations or realize anticipated benefits of the integration. 

 We may not complete the Utica Shale Divestiture within the anticipated timeframe or at all. 

The completion of the Utica Shale Divestiture is subject to a number of conditions.  The failure to satisfy all of the required 

conditions could delay the completion of the Utica Shale Divestiture for a significant period of time or prevent it from occurring at all.  
A delay in completing the Utica Shale Divestiture could cause us to realize some or all of the benefits later than we otherwise expect 
to realize them if the Utica Shale Divestiture was successfully completed within the anticipated timeframe, which could result in 
additional transaction costs or in other negative effects associated with uncertainty around completion of the divestiture. 

Notwithstanding the due diligence investigation that we performed in connection with our entry into the definitive agreement 
to purchase HG Midstream, HG Midstream may have liabilities, losses or other exposures for which we do not have adequate 
insurance coverage or other protection. 

While we performed due diligence on HG Midstream prior to our entry into the definitive agreement to purchase HG 

Midstream, we are dependent on the accuracy and completeness of statements and disclosures made or actions taken by HG 
Midstream and its representatives when conducting due diligence and evaluating the results of such due diligence.  We do not control 
and may be unaware of activities of HG Midstream prior to the completion of the HG Acquisition, including intellectual property and 
other litigation, claims or disputes, information security vulnerabilities, violations of laws, policies, rules and regulations, commercial 
disputes, tax liabilities and other known and unknown liabilities. 

With the consummation of the HG Acquisition, the liabilities of HG Midstream, including contingent liabilities, will be 

consolidated with our liabilities for purposes of financial reporting.  HG Midstream may have unknown liabilities which we will be 
responsible for following the consummation of the HG Acquisition.  If HG Midstream’s liabilities are greater than expected, or if there 
are obligations of HG Midstream of which we are not aware, our business could be materially and adversely affected.  We do not have 
indemnification rights from the current owners of HG Midstream for defects and liabilities associated with the acquired assets and 
instead will rely on a limited representation and warranty insurance policy, which we have obtained.  Such insurance is subject to 
exclusions, policy limits and certain other customary terms and conditions.  If we are responsible for liabilities not covered by 
representation and warranty insurance, we could suffer consequences that could have a material adverse effect on our financial 
condition and results of operations. 

We may be unable to make attractive acquisitions or successfully integrate acquired businesses, and any inability to do so may 
disrupt our business and hinder our ability to grow. 

In the future, we may acquire businesses that complement or expand our current business.  We may not be able to identify 
attractive acquisition opportunities.  Even if we do identify attractive acquisition opportunities, we may not be able to complete the 
acquisition or do so on commercially acceptable terms. 

In connection with acquisitions, we perform a review of the subject assets that we believe to be generally consistent with 

industry practices.  However, our review will not reveal all existing or potential problems.  For example, certain environmental 
problems are not necessarily observable even when an inspection is undertaken.  Even when problems are identified, the seller may be 
unwilling or unable to provide effective contractual protection against all or part of the problems.  Even if we are able to obtain 

25 

Table of Contents  
contractual indemnification rights, there is no assurance that the seller will be capable of performing under any indemnification 
obligation. 

The success of any completed acquisition will depend on our ability to effectively integrate the acquired business into our 

existing operations.  The process of integrating acquired businesses may involve unforeseen difficulties and may require a 
disproportionate amount of our managerial and financial resources.  In addition, possible future acquisitions may be larger and for 
purchase prices significantly higher than those paid for earlier acquisitions.  No assurance can be given that we will be able to identify 
suitable acquisition opportunities, negotiate acceptable terms, obtain financing for acquisitions on acceptable terms or successfully 
acquire identified targets.  Our failure to achieve consolidation savings, to successfully integrate the acquired businesses and assets 
into our existing operations or to minimize any unforeseen operational difficulties could have a material adverse effect on our 
business, financial condition and results of operations. 

In addition, our agreements governing our debt impose certain limitations on our ability to enter into mergers or combination 

transactions.  The Credit Facility and the indentures governing our senior notes also limit our ability to incur certain indebtedness, 
which could indirectly limit our ability to engage in acquisitions of businesses. 

Our certificate of incorporation and bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids 
or merger proposals, which may adversely affect the market price of our common stock.  

Certain provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire 

control of us, even if the change of control would be beneficial to our stockholders.  Among other things, our certificate of 
incorporation and bylaws: 

• 

• 

• 

• 

• 

• 

• 

• 

provide advance notice procedures with regard to stockholder nominations of candidates for election as directors or other 
stockholder proposals to be brought before meetings of our stockholders, which may preclude our stockholders from 
bringing certain matters before our stockholders at an annual or special meeting;  

provide our Board of Directors (the “Board”) the ability to authorize issuance of preferred stock in one or more classes or 
series, which makes it possible for our Board to issue, without stockholder approval, preferred stock with voting or other 
rights or preferences that could impede the success of any attempt to change control of us and which may have the effect 
of deterring hostile takeovers or delaying changes in control or management of us;  

provide that the authorized number of directors may be changed only by resolution of our Board;  

provide that, subject to the rights of holders of any series of preferred stock to elect directors or fill vacancies in respect 
of such directors as specified in the related preferred stock designation and the terms of that certain Stockholders’ 
Agreement, dated October 9, 2018, by and among Antero Midstream Corporation and certain of its stockholders named 
thereto (the “Stockholders’ Agreement”), all vacancies, including newly created directorships be filled by the affirmative 
vote of holders of a majority of directors then in office, even if less than a quorum, or by the sole remaining director, and 
will not be filled by our stockholders;  

provide that, subject to the rights of the holders of any series of preferred stock to elect directors under specified 
circumstances, if any, and the terms of the Stockholders’ Agreement, any action required or permitted to be taken by our 
stockholders must be effected at a duly called annual or special meeting of our stockholders and may not be effected by 
any consent in writing in lieu of a meeting of such stockholders;  

provide for our Board to be divided into three classes of directors, with each class as nearly equal in number as possible, 
serving staggered three-year terms; 

provide that, subject to the rights of the holders of shares of any series of preferred stock, if any, to remove directors 
elected by such series of preferred stock pursuant to our certificate of incorporation (including any preferred stock 
designation thereunder) and the terms of the Stockholders’ Agreement, directors may be removed from office at any 
time, only for cause and by the holders of a majority of the voting power of all outstanding voting shares entitled to vote 
generally in the election of directors;  

provide that special meetings of our stockholders may only be called by the Chief Executive Officer, the Chairman of 
our Board or our Board pursuant to a resolution adopted by a majority of the total number of directors that we would 
have if there were no vacancies;

provision of our certificate of incorporation may be amended, altered or repealed in any manner that would be contrary 
to or inconsistent with the terms of the Stockholders’ Agreement, and no amendment to the Stockholders’ Agreement 
(regardless of whether such amendment modifies any provision of the Stockholders’ Agreement to which our certificate 
of incorporation is subject) will be deemed an amendment of our certificate of incorporation; and  

provide that our bylaws can be altered or repealed by (a) our Board or (b) our stockholders upon the affirmative vote of 
holders of at least 66 2/3% of the voting power of our common stock outstanding and entitled to vote thereon, voting

approve any amendment, alteration or repeal of any provision of our bylaws or the adoption of any new bylaw, that 
(a) would be contrary to or inconsistent with the terms of the Stockholders’ Agreement or (b) would amend, alter or 
repeal certain portions of our certificate of incorporation; provided, however, that so long as the Stockholders’ 
Agreement remains in effect, the parties to the Stockholders' Agreement may amend any provision of the Stockholders’ 
Agreement, and no amendment to the Stockholders’ Agreement (regardless of whether such amendment modifies any 
provision of the Stockholders’ Agreement to which the bylaws are subject) will be deemed an amendment of the bylaws 
for purposes of the amendment provisions of our bylaws.  

We have elected not to be subject to the provisions of Section 203 of the Delaware General Corporation Law (the “DGCL”), 
regulating corporate takeovers.  

In general, the provisions of Section 203 of the DGCL prohibit a Delaware corporation, including those whose securities are 
listed for trading on the New York Stock Exchange, from engaging in any business combination with any interested stockholder for a 
period of three years following the date that the stockholder became an interested stockholder, unless: 

• 

• 

• 

prior to such time, the business combination or the transaction which resulted in the stockholder becoming an interested 
stockholder is approved by our Board;  

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested 
stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced 
(excluding certain specified shares); or  

on or after such time the business combination is approved by our Board and authorized at a meeting of stockholders by 
the holders of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.  

Section 203 of the DGCL permits a Delaware corporation to elect not to be governed by the provisions of Section 203.  

Pursuant to our certificate of incorporation, we expressly elected not to be governed by Section 203.  Accordingly, we are not subject 
to any anti-takeover effects or protections of Section 203 of the DGCL, although no assurance can be given that we will not elect to be 
governed by Section 203 of the DGCL pursuant to an amendment to our certificate of incorporation in the future. 

Joint Ventures 

We own a 50% interest in the Joint Venture, which is operated by MarkWest.  While we have the ability to influence certain 
business decisions affecting the Joint Venture, the success of our investment in the Joint Venture will depend on MarkWest’s 
operation of the Joint Venture. 

On February 6, 2017, we entered into the Joint Venture with MarkWest.  While we and MarkWest each own a 50% interest 

in the Joint Venture, MarkWest is the primary operator of the Joint Venture, and we depend on MarkWest for the day-to-day 
operations of the Joint Venture.  Our lack of control over the Joint Venture’s day-to-day operations and the associated costs of 

27 

Table of Contents  
operations could result in receiving lower cash distributions from the Joint Venture than currently anticipated.  In addition, differences 
in views among the owners of the Joint Venture could result in delayed decisions or in failures to agree on significant matters, 
potentially adversely affecting the business and results of operations or prospects of the Joint Venture and, in turn, the amount of cash 
from the Joint Venture operations distributed to us. 

If the Joint Venture is not successful or if the Joint Venture does not perform as expected, our future financial performance 
may be negatively impacted. 

We may be exposed to certain risks in connection with our ownership interest in the Joint Venture, including regulatory, 

environmental and litigation risks.  If such risks or other anticipated or unanticipated liabilities were to materialize, any desired 
benefits of our entry into the Joint Venture may not be fully realized, if at all, and its future financial performance may be negatively 
impacted. 

In addition, the Joint Venture may result in other difficulties including, among other things: 

• 

diversion of our management’s attention from other business concerns; 

•  managing regulatory compliance and corporate governance matters; 

• 

• 

an increase in our indebtedness; and 

potential environmental or other regulatory compliance matters or liabilities and/or title issues, including certain 
liabilities arising from the operation of the Joint Venture assets prior to the closing of the Joint Venture. 

Interruptions in operations at any of the Joint Venture’s facilities may adversely affect its operations and our gathering and 
processing and water handling operations. 

The Joint Venture assets consist of processing plants in West Virginia and a one-third interest in two fractionators in Ohio 

(the “MarkWest fractionators”).  Any significant interruption at these facilities would adversely affect the Joint Venture’s operations.  
Because a significant portion of Antero Resources’ production is processed by the Joint Venture, any significant interruption at these 
facilities would also adversely affect our other midstream operations. 

We do not operate the MarkWest fractionators, and the operations of the MarkWest’s and Joint Venture’s processing 

facilities and the MarkWest fractionators could be partially or completely shut down, temporarily or permanently, as the result of 
circumstances not within its control, such as: 

• 

• 

• 

• 

• 

• 

• 

unscheduled turnarounds or catastrophic events, including damages to facilities, related equipment and surrounding 
properties caused by earthquakes, tornadoes, hurricanes, floods, fires, severe weather, explosions and other natural 
disasters; 

restrictions imposed by governmental authorities or court proceedings; 

labor difficulties that result in a work stoppage or slowdown; 

a disruption in the supply of gas to MarkWest’s or the Joint Venture’s processing and fractionation plants and associated 
facilities; 

disruption in the supply of power, water and other resources necessary to operate MarkWest’s or the Joint Venture’s 
facilities; 

damage to MarkWest’s or the Joint Venture’s facilities resulting from gas that does not comply with applicable 
specifications; and 

inadequate fractionation capacity or market access to support production volumes, including lack of availability of rail 
cars, barges, pipeline capacity or market constraints, including reduced demand or limited markets for certain NGLs. 

In addition, MarkWest’s fractionation operations in the Appalachian Basin are integrated, and as a result, it is possible that an 

interruption of these operations in other regions may impact operations in the regions in which the Joint Venture’s facilities are 
located. 

28 

Table of Contents  
Compliance with Regulations 

We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or 
feasibility of conducting our operations or expose us to significant liabilities. 

Our operations are subject to complex and stringent federal, state and local laws and regulations.  In order to conduct our 

operations in compliance with these laws and regulations, we must obtain and maintain numerous permits, approvals and certificates 
from various federal, state and local governmental authorities.  We may incur substantial costs in order to maintain compliance with 
these existing laws and regulations and the permits and other approvals issued thereunder.  In addition, our costs of compliance may 
increase or operational delays may occur if existing laws and regulations are revised or reinterpreted, or if new laws and regulations 
apply to our operations.  Failure to comply with such laws and regulations, including any evolving interpretation and enforcement by 
governmental authorities, could have a material adverse effect on our business, financial condition and results of operations.  Also, we 
might not be able to obtain or maintain all required environmental regulatory approvals for our operations.  If there is a delay in 
obtaining any required environmental regulatory approvals, or if we fail to obtain and comply with them, the operation or construction 
of our facilities could be prevented or become subject to additional costs. 

In addition, new or additional regulations, new interpretations of existing requirements or changes in our operations could 

also trigger the need for Environmental Assessments or more detailed Environmental Impact Statements under the National 
Environmental Policy Act (“NEPA”) and analogous state laws, or that impose new permitting requirements on our operations could 
result in increased costs or delays of, or denial of rights to conduct, our development programs.  For instance, there have been several 
recent developments regarding the NEPA regulatory regime.  Most recently, following a Trump administration Executive Order, in 
February 2025, the White House’s Council on Environmental Quality (“CEQ”) released an interim final rule rescinding its regulations 
implementing NEPA.  Federal agencies have begun the process of preparing their own new or updated NEPA-implementing rules or 
guidelines, with the first batch of updates released in July 2025.  In May 2025, the Supreme Court issued its opinion in Seven County 
Infrastructure Coalition v. Eagle County, emphasizing the “substantial judicial deference” that courts must grant agencies when 
considering NEPA challenges.  And, in September 2025, CEQ issued new guidance to federal agencies implementing NEPA 
encouraging them to limit their NEPA reviews, rely more heavily on sponsor-prepared documents, and streamline the NEPA process.  
The full impact of these developments remains unclear at this time, but any disruption in our ability to obtain permits could result in 
costs that could have a material adverse effect on our business, financial condition and results of operations. 

Further, in April 2020, the federal district court for the District of Montana determined that the CWA Section 404 NWP 12 
failed to comply with consultation requirements under the federal Endangered Species Act.  The district court vacated NWP 12 and 
enjoined the issuance of new authorizations for oil and gas pipeline projects.  While the district court’s order has subsequently been 
limited to the particular pipeline in that case pending appeal, we cannot predict the ultimate outcome of this case and its impacts to the 
NWP program.  Relatedly, in response to the vacatur, the Corps reissued NWP 12 for oil and natural gas pipeline activities, including 
certain revisions to the conditions for the use of NWP 12; however, an October 2021 decision by the District Court for the Northern 
District of California resulted in a vacatur of a 2020 rule revising the CWA Section 401 certification process.  The U.S. Supreme 
Court has since stayed this vacatur and the EPA published a rule to update and replace the relevant regulations in September 2023.  
Several states challenged the rule.  In January 2026, the EPA published a proposed rule revising its regulations governing the CWA 
Section 401 certification process.  Additionally, in March 2022, the Corps announced that it was seeking stakeholder input on a formal 
review of NWP 12.  While the full extent and impact of these developments is unclear at this time, any disruption in our ability to 
obtain coverage under NWP 12 or other general permits may result in increased costs and project delays if we are forced to seek 
individual permits from the Corps.  This in turn could have an adverse effect on our business, financial condition and results of 
operation. 

Separately, the definition of WOTUS has been subject to substantial controversy, with the Corps and EPA pursuing several 
WOTUS rulemakings since 2015.  In September 2023, the EPA issued a WOTUS rule that is currently only implemented in 24 states 
due to ongoing litigation.  However, in November 2025, the EPA and the Corps proposed a rule to further update and narrow this 
September 2023 definition of WOTUS, guided by the Sackett v. EPA decision.  To the extent any judicial ruling, administrative 
rulemaking, or other action further changes the scope of the CWA’s jurisdiction, we could face increased costs and delays with respect 
to obtaining permits for dredge and fill activities in wetland areas.  Such potential regulations or litigation could increase our operating 
costs, reduce our liquidity, delay or halt our operations or otherwise alter the way we conduct our business, which could in turn have a 
material adverse effect on our business, financial condition and results of operations.  We cannot predict what, when or how the 
Trump administration may take action with respect to any of these regulations.  Further, any discharges of natural gas, NGLs, oil and 
other pollutants into the air, soil or water may give rise to significant liabilities on our part to the government and third parties.  See 
“Item 1. Business—Regulation of Environmental and Occupational Safety and Health Matters” for a further description of laws and 
regulations that affect us.

Table of Contents  
If our assets become subject to FERC regulation or federal, state or local regulations or policies change, or if we fail to comply 
with market behavior rules, our financial condition, cash flows and results of operations could be materially and adversely 
affected. 

Our gathering and transportation operations are exempt from regulation by the FERC, under the NGA.  Section 1(b) of the 
NGA, exempts natural gas gathering facilities from regulation by the FERC under the NGA.  Although the FERC has not made any 
formal determinations with respect to any of our facilities, we believe that the natural gas pipelines in our gathering systems meet the 
traditional tests the FERC has used to establish whether a pipeline is a gathering pipeline not subject to FERC jurisdiction.  The 
distinction between FERC-regulated transmission services and federally unregulated gathering services, however, has been the subject 
of substantial litigation, and the FERC determines whether facilities are gathering facilities on a case-by-case basis, so the 
classification and regulation of our gathering facilities may be subject to change based on future determinations by the FERC, the 
courts or Congress.  If the FERC were to consider the status of an individual facility and determine that the facility or services 
provided by it are not exempt from FERC regulation under the NGA, the rates for, and terms and conditions of, services provided by 
such facility would be subject to regulation by the FERC under the NGA or the NGPA.  Such regulation could decrease revenue, 
increase operating costs and, depending upon the facility in question, could adversely affect our financial condition, cash flows and 
results of operations. 

State regulation of natural gas gathering facilities and intrastate transportation pipelines generally includes various safety, 

environmental and, in some circumstances, nondiscriminatory take and common purchaser requirements, as well as complaint-based 
rate regulation.  Other state regulations may not directly apply to our business, but may nonetheless affect the availability of natural 
gas for purchase, compression and sale. 

Moreover, FERC regulations indirectly impact our businesses and the markets for products derived from these businesses.  

The FERC’s policies and practices across the range of its natural gas regulatory activities, including, for example, its policies on open 
access transportation, market manipulation, ratemaking, gas quality, capacity release and market center promotion, indirectly affect 
the intrastate natural gas market.  Should we fail to comply with any applicable FERC administered statutes, rules, regulations and 
orders, we could be subject to substantial penalties and fines, which could have a material adverse effect on our financial condition, 
cash flows and results of operations.  The FERC has civil penalty authority under the NGA and NGPA to impose penalties for current 
violations of up to $1,584,648 per day for each violation and disgorgement of profits associated with any violation. 

For more information regarding federal and state regulation of our operations, see “Business—Regulation of Operations.” 

Increased regulation of hydraulic fracturing could result in reductions or delays in production by our customers, which could 
reduce the throughput on our gathering and processing systems and the number of wells for which we provide water handling 
services, which could adversely impact our revenues. 

All of Antero Resources’ natural gas, NGLs and oil production is developed from unconventional sources, such as shale 

formations.  These reservoirs require hydraulic fracturing completion processes to release the liquids and natural gas from the rock so 
it can flow through casing to the surface.  Hydraulic fracturing is a well stimulation process that utilizes large volumes of water and 
sand (or other proppant) combined with fracturing chemical additives that are pumped at high pressure to crack open previously 
impenetrable rock to release hydrocarbons.  Hydraulic fracturing is typically regulated by state oil and gas commissions and similar 
agencies, but the EPA has asserted federal regulatory authority over certain hydraulic fracturing activities. 

In addition, Congress has from time to time considered legislation to provide for federal regulation of hydraulic fracturing 

under the Safe Drinking Water Act and to require disclosure of the chemicals used in the hydraulic fracturing process.  New 
legislation regulating hydraulic fracturing may be considered again in future, though we cannot predict when or the scope of any such 
legislation at this time.  At the state level, several states have adopted or are considering legal requirements that could impose more 
stringent permitting, disclosure and well construction requirements on hydraulic fracturing activities.  For example, both West 
Virginia and Ohio have adopted requirements governing well pad construction, as well as requiring oil and natural gas operators to 
disclose chemical ingredients used to hydraulically fracture wells and to conduct pre-drilling baseline water quality sampling of 
certain water wells near a proposed horizontal well.  Local governments also may seek to adopt ordinances within their jurisdictions 
regulating the time, place and manner of drilling activities in general or hydraulic fracturing activities in particular. 

We cannot predict whether any such legislation will ever be enacted and if so, what its provisions would be.  If additional 

levels of regulation and permits were required through the adoption of new laws and regulations at the federal, state or local level, that 
could lead to delays, increased operating costs and process prohibitions that could reduce the amount of natural gas that moves 
through our gathering and processing systems or reduce the number of wells drilled and completed that require fresh water for 
hydraulic fracturing activities, which in turn could materially and adversely affect our revenues and results of operations.

We or any third-party customers may incur significant liability under, or costs and expenditures to comply with, 
environmental and occupational health and workplace safety regulations, which are complex and subject to frequent change. 

As an owner, lessee or operator of gathering pipelines and compressor stations, we are subject to various stringent federal, 

state, provincial and local laws and regulations relating to the discharge of materials into, and protection of, the environment.  
Numerous governmental authorities, such as the EPA and analogous state agencies, have the power to enforce compliance with these 
laws and regulations and the permits issued under them, oftentimes requiring difficult and costly response actions.  These laws and 
regulations may impose various obligations that are applicable to our and our customer’s operations, including the acquisition of 
permits to conduct regulated activities, the incurrence of capital or operating expenditures to limit or prevent releases of materials 
from our or our customers’ operations, the imposition of specific standards addressing worker protection and the imposition of 
substantial liabilities and remedial obligations for pollution or contamination resulting from our and our customer’s operations.  
Failure to comply with these laws, regulations and permits may result in joint and several, strict liability and the assessment of 
administrative, civil and criminal penalties, the imposition of remedial obligations and the issuance of injunctions limiting or 
preventing some or all of our operations.  Private parties, including the owners of the properties through which our gathering systems 
pass and facilities where wastes resulting from our operations are taken for reclamation or disposal, may also have the right to pursue 
legal actions to enforce compliance, as well as to seek damages for non-compliance, with environmental laws and regulations or for 
personal injury or property damage.  We may not be able to recover all or any of these costs from insurance.  In addition, we may 
experience a delay in obtaining or be unable to obtain required permits, which may cause us to lose potential and current customers, 
interrupt our operations and limit our growth and revenues, which in turn could affect our profitability.  There is no assurance that 
changes in or additions to public policy regarding the protection of the environment will not have a significant impact on our 
operations and profitability.  While the Trump administration may make changes to President Biden’s environmental and climate 
change initiatives, we cannot predict what, when or how the new administration may take actions to revise existing environmental 
laws or regulations, if at all, or the ultimate impact such changes may have on our business. 

Our operations also pose risks of environmental liability due to potential leakage, migration, releases or spills from our 

operations to surface or subsurface soils, surface water or groundwater.  Certain environmental laws impose strict as well as joint and 
several liability for costs required to remediate and restore sites where hazardous substances, hydrocarbons or solid wastes have been 
stored or released.  We may be required to remediate contaminated properties currently or formerly operated by us or facilities of third 
parties that received waste generated by our operations regardless of whether such contamination resulted from the conduct of others 
or from consequences of our own actions that were in compliance with all applicable laws at the time those actions were taken.  In 
addition, claims for damages to persons or property, including natural resources, may result from the environmental, health and safety 
impacts of our operations.  Moreover, public interest in the protection of the environment has increased dramatically in recent years.  
The trend of more expansive and stringent environmental legislation and regulations is expected to continue, which may result in 
increased costs of doing business and consequently affecting profitability.  See “Business—Regulation of Environmental and 
Occupational Safety and Health Matters” for more information. 

The Inflation Reduction Act could adversely impact demand for oil and gas and could impose new costs on our operations and 
those of our customers. 

In August 2022, President Biden signed the IRA 2022 into law.  The IRA 2022 contains hundreds of billions of dollars in 

incentives for the development of renewable energy, clean hydrogen, clean fuels, electric vehicles and supporting infrastructure and 
carbon capture and sequestration, amongst other provisions.  However, on January 20, 2025, President Trump issued an Executive 
Order directing agencies to immediately pause the disbursement of funds appropriated through the IRA 2022.  The full impact of this 
Executive Order and related administrative actions is uncertain at this time.  In addition, the IRA 2022 imposed the first ever federal 
fee on the emission of greenhouse gases through a methane emissions charge.  The IRA 2022 amended the federal Clean Air Act to 
impose a fee on the emission of excess methane from sources required to report their GHG emissions to the EPA, including those 
sources in the onshore petroleum and natural gas production and gathering and boosting source categories.  The EPA finalized a rule 
implementing this charge in November 2024; however, in February 2025, Congress repealed the rule under the Congressional Review 
Act.  Additionally, under the OBBB, Congress delayed the implementation of the methane emissions charge until 2034.  Compliance 
with the methane emissions charge and other air pollution control and permitting requirements could impose additional costs on our 
operations and reduce demand for oil and natural gas.  Consequently, this could adversely affect our business and results of operations 
and those of our customers.  We cannot predict what, when, or how the Trump administration or Congress may take further actions to 
rollback or otherwise revise existing laws, rules, or regulations or the ultimate impact such changes may have on our business 
operations.

Our operations are subject to a series of risks related to climate that could result in increased operating costs, limit the areas 
in which our customers may conduct oil and gas exploration and production activities, and reduce demand for the services we 
provide. 

Climate risks continue to attract considerable attention in the United States and in foreign countries.  In the United States, no 

comprehensive climate legislation has been implemented at the federal level.  Federal regulators, state and local governments and 
private parties have taken (or announced that they plan to take) actions that have or may have a significant influence on our 
operations.  The EPA has adopted regulations under existing provisions of the federal CAA that, among other things, establish PSD 
construction and Title V operating permit reviews for certain large stationary sources that are already potential major sources of 
certain principal, or criteria, pollutant emissions.  Facilities required to obtain PSD permits for their GHG emissions also will be 
required to meet “best available control technology” standards that will be established by the states or, in some cases, by the EPA for 
those emissions.  These EPA rules could adversely affect our operations and restrict or delay our ability to obtain air permits for new 
or modified sources.  In addition, the EPA has adopted rules requiring the monitoring and reporting of GHG emissions from specified 
onshore and offshore oil and gas production sources in the United States on an annual basis, which include certain of our operations.  
Although the EPA has proposed to delay GHG reporting for the oil and gas sector until 2034, and to otherwise repeal GHG reporting 
requirements for other sectors, we cannot predict whether these efforts will ultimately be successful or that GHG reporting will not be 
required again in the future.  Existing climate change-related regulation have been a focus of the Trump administration.  On his first 
day in office, President Trump signed several Executive Orders rescinding many of the previous administration’s Executive Orders 
and associated climate-related initiatives.  President Trump’s directives included, amongst others, directing the EPA to reconsider its 
2009 endangerment findings relating to GHGs, which provides regulatory justification for federal GHG permitting and methane 
emission control requirements, and directing the EPA to reconsider its use of Social Cost of GHG estimates in federal permitting 
decisions.  To that end, in March 2025, the EPA announced formal reconsideration of both the Social Cost of GHG estimates and the 
2009 endangerment finding and, in July 2025, released a proposal to rescind the latter.  We cannot predict the ultimate impact of these 
actions or any similar changes on our business or results of operations. 

The federal regulation of methane from oil and gas facilities has been subject to substantial uncertainty in recent years.  In 

December 2023, the EPA finalized more stringent methane rules for new, modified, and reconstructed facilities, known as OOOOb, as 
well as standards for existing sources for the first time ever, known as OOOOc.  However, in March 2025, the EPA announced plans 
to reconsider OOOOb and OOOOc, in line with the Trump administration’s deregulatory agenda.  Additionally, in November 2025, 
the EPA finalized an interim rule extending the compliance deadlines for certain provisions provided in OOOOb and OOOOc.  
Litigation challenging the EPA’s final interim rule extending such compliance deadlines for new and existing oil and gas sources 
remains pending.  We cannot predict what additional actions the Trump administration may take or how they may affect our business 
operations.  However, failure to comply with these CAA requirements can result in the imposition of substantial fines and penalties as 
well as costly injunctive relief.  Given the long-term trend toward increasing regulation, future federal GHG regulations of the oil and 
gas industry remain a possibility, and several states, including West Virginia and Ohio, have separately imposed their own regulations 
on methane emissions from oil and gas production activities. 

Increasingly, oil and natural gas companies are also exposed to litigation risks related to climate risks.  While we are not 
currently party to any such litigation, we could be named in future actions making similar claims of liability and, depending on the 
nature of the claims asserted and other factors, such liability could be imposed without regard to the company’s causation of or 
contribution to the asserted damage, or to other mitigating factors. 

Additionally, companies in the oil and natural gas industry may be exposed to increasing financial risks.  Financial 
institutions, including investment advisors and certain sovereign wealth, pension and endowment funds, may elect in the future to shift 
some or all of their investment into non-oil and natural gas related industries.  Certain institutional lenders who provide financing to 
oil and natural gas companies have also become more attentive to lending practices, and some of them may elect in future not to 
provide funding for oil and natural gas companies, although this trend has been decreasing.  To the extent implemented or pursued, 
such policies and commitments could lead to some lenders restricting access to capital for or divesting from certain industries or 
companies, including the oil and natural gas sector, or requiring that borrowers take additional steps to reduce their GHG emissions.  
There is also a risk that financial institutions will be required to adopt policies that have the effect of reducing the funding provided to 
the oil and natural gas industry.  While we cannot predict how or to what extent sustainable lending and investment practices may 
impact our operations, a material reduction in the capital available to the oil and natural gas industry could make it more difficult to 
secure funding for exploration, development, production, transportation and processing activities, which could result in decreased 
demand for our midstream services. 

In addition, in October 2023, some states have adopted or are considering adopting laws requiring the disclosure of climate-

related risks.  Lawsuits have been filed challenging the implementation of one of these laws, but we cannot predict the outcome of 
these suits at this time.  Compliance with these laws, to the extent implemented and applicable to us, may result in additional costs 

32 

Table of Contents  
related to disclosure requirements as well as increased costs of and restrictions on access to capital.  Separately, enhanced climate 
related disclosure requirements could lead to reputational or other harm and could also increase our litigation risks relating to 
statements alleged to have been made by us or others in our industry regarding climate risks, or in connection with any future 
disclosures we may make regarding reported emissions, particularly given the inherent uncertainties and estimations with respect to 
calculating and reporting GHG emissions. 

The adoption and implementation of new or more stringent international, federal or state legislation, regulations or other 
regulatory initiatives related to climate risks or GHG emissions from oil and natural gas facilities could result in increased costs of 
compliance or costs of consumption, thereby reducing demand for the services we provide.  One or more of these developments could 
have a material adverse effect on our business, financial condition and results of operation. 

We may incur significant costs and liabilities as a result of pipeline integrity management program testing and any related 
pipeline repair or preventative or remedial measures. 

The DOT has adopted regulations requiring pipeline operators to develop integrity management programs for transportation 

pipelines located where a leak or rupture could do the most harm in HCAs or MCAs.  The regulations require operators to: 

• 

• 

• 

• 

• 

perform ongoing assessments of pipeline integrity; 

identify and characterize applicable threats to pipeline segments that could impact certain high risk areas; 

improve data collection, integration and analysis; 

repair and remediate the pipeline as necessary; and 

implement preventive and mitigating actions. 

The 2011 Pipeline Safety Act among other things, increased the maximum civil penalty for pipeline safety violations and 
directed the Secretary of Transportation to promulgate rules or standards relating to expanded integrity management requirements, 
automatic or remote-controlled valve use, excess flow valve use, leak detection system installation and testing to confirm the material 
strength of pipe operating above 30% of specified minimum yield strength in HCAs.  Consistent with the 2011 Pipeline Safety Act, 
the PHMSA, finalized rules that increased the maximum administrative civil penalties for violations of the pipeline safety laws and 
regulations to $200,000 per violation per day, with a maximum of $2,000,000 for a related series of violations.  In December 2024, 
those maximum civil penalties were increased to $272,926 and $2,729,245, respectively, to account for inflation.  Should our 
operations fail to comply with DOT or comparable state regulations, we could be subject to substantial penalties and fines. 

Following legislation enacted by Congress, PHMSA has issued or proposed regulations that either seek to impose new 

obligations on pipeline operations or expand existing pipeline safety requirements to previously unregulated pipelines.  For example, 
in November 2021, PHMSA issued a final rule that imposes safety regulations on approximately 400,000 miles of previously 
unregulated onshore gas gathering lines that, among other things, will impose criteria for inspection and repair of fugitive emissions, 
extend reporting requirements to all gas gathering operators and apply a set of minimum safety requirements to certain gas gathering 
pipelines with large diameters and high operating pressures.  In August 2022, PHMSA finalized the rule entitled “Pipeline Safety: 
Safety of Gas Transmission Pipelines, Repair Criteria, Integrity Management Improvements, Cathodic Protection, Management of 
Change and Other Related Amendments” which adjusted the repair criteria for pipelines in HCAs, created new criteria for pipelines in 
non-HCAs and strengthened integrity management assessment requirements, among other items.  However, in August 2024, the U.S. 
Court of Appeals for the D.C. Circuit vacated various aspects of the 2022 rule.  In April 2024, PHMSA promulgated a final rule that 
amended Federal pipeline safety regulations to incorporate more than 20 new or updated voluntary, consensus industry technical 
standards to allow pipeline operators to use current technologies and improved materials.  In January 2025, PHMSA finalized a rule 
that enhances the safety requirements for gas distribution pipelines and requires updates to distribution integrity management 
programs, emergency response plans, operations and maintenance manuals and other safety practices.  However, the Trump 
administration withdrew the final rule shortly thereafter, and, accordingly, it has not been codified.  We do not expect our operations 
to be affected by these new rules or rule changes any differently than other similarly situated midstream companies.  While we cannot 
predict the full scope of these regulations at this time, more stringent requirements may require us to incur significant costs to maintain 
compliance, which may have a negative impact on our business performance and results of operations. 

The adoption of these and other laws or regulations that apply more comprehensive or stringent safety standards could 

require us to install new or modified safety controls, pursue new capital projects or conduct maintenance programs on an accelerated 
basis, all of which could require us to incur increased operational costs that could be significant, consistent with other similarly 
situated midstream companies.  While we cannot predict the outcome of legislative or regulatory initiatives, such legislative and 

33

regulatory changes could have a material effect on our cash flow.  See “Business—Pipeline Safety Regulation” for more information. 

Regulations related to the protection of wildlife could adversely affect our ability to conduct oil and gas operations in some of 
the areas where we operate. 

Oil and gas operations in our operating areas can be adversely affected by regulations designed to protect various wildlife.  

For example, following a 2020 court order to reconsider its decision to list the northern long-eared bat as threatened instead of 
endangered, the USFWS redesignated the bat as endangered under the ESA.  The designation of previously unprotected species as 
threatened or endangered, or redesignation of a threatened species as endangered, in areas where we operate could cause us to incur 
increased costs arising from species protection measures, result in constraints on our customer’s exploration and production activities 
and on our pipeline construction and operation activities.  This limits our ability to operate in those areas and can intensify competition 
during those months for drilling rigs, oilfield equipment, services, supplies and qualified personnel, which may lead to periodic 
shortages.  These constraints and the resulting shortages or high costs could delay our operations or the operations of our customers 
and materially increase our operating and capital costs. 

Human Capital  

The loss of senior management or technical personnel could adversely affect operations. 

We depend on the services of a relatively small group of senior management and technical personnel.  We do not maintain, 

nor do we plan to obtain, any insurance against the loss of any of these individuals.  The loss of the services of our senior management 
or technical personnel, including Michael N. Kennedy, Chief Executive Officer and President, could have a material adverse effect on 
our business, financial condition and results of operations. 

Our officers and employees provide services to both Antero Resources and us.  

All of our executive officers and certain other personnel who provide corporate, general and administrative services to our 
business are, when providing services to us, concurrently employed by Antero Resources and us pursuant to the terms of a services 
agreement.  In addition, our operational personnel are seconded to us by Antero Resources pursuant to the terms of a secondment 
agreement and are concurrently employed by Antero Resources and us during such secondment.  As a result, there could be material 
competition for the time and effort of the officers and employees who provide services to Antero Resources and us.  If such officers 
and employees do not devote sufficient attention to the management and operation of our business, our financial results may suffer. 

Related Parties 

Antero Resources owns a significant interest in us and, as a result, conflicts of interest will arise from time to time between it 
and us, and Antero Resources may favor their own interests to the detriment of us and our other stockholders.  Additionally, 
Antero Resources is under no obligation to adopt a business strategy that favors us. 

All of our officers and certain of our directors are also officers or directors of Antero Resources.  Also, as of December 31, 
2025, Antero Resources beneficially owned 29% of our outstanding common stock.  Conflicts of interest will arise between Antero 
Resources and us.  Our directors and officers who are also directors and officers of Antero Resources have a fiduciary duty to manage 
Antero Resources in a manner that is beneficial to Antero Resources.  In resolving these actual or apparent conflicts of interest, these 
directors and officers may choose strategies that favor Antero Resources over our interests and the interests of our stockholders.  
These actual and apparent conflicts may in certain cases include, for example, the decision to declare and pay dividends or the 
decision to repurchase shares of our common stock owned by Antero Resources.  The resolution of any conflicts of interest between 
Antero Resources and its subsidiaries, on one hand, and us and our subsidiaries, on the other, to the extent we can resolve them, may 
be costly and reduce the amount of time and attention that our directors and officers may spend in operating our business, which, in 
each case, may adversely affect our business. 

Furthermore, Antero Resources is under no obligation to adopt a business strategy that favors us.  For example, Antero 
Resources has dedicated acreage to, and entered into long-term contracts for gathering and compression services on, our gathering and 
compression systems, as well as long-term contracts for receiving water services.  However, while we have a right of first offer that 
expires in 2038 to provide processing and fractionation services to Antero Resources, subject to certain exceptions, Antero Resources 
is under no obligation to consider whether any future drilling plans would create beneficial opportunities for us.  Additionally, 
although our processing and fractionation services provided by the Joint Venture are supported by minimum volume commitments, 
the gathering and compression agreements include minimum volumes commitments only on high pressure pipelines and/or 
compressor stations constructed at Antero Resources’ request.  Any decision by Antero Resources to operate its assets in a manner 
that does not support our operations could have a material adverse effect on our business, financial condition and results of operations.

We are a holding company whose sole material asset is our equity interest in Antero Midstream Partners, and we are 
accordingly dependent upon distributions from Antero Midstream Partners to pay taxes, return capital to stockholders and 
cover our corporate and other overhead expenses. 

We are a holding company and have no material assets other than our equity interest in Antero Midstream Partners.  We have 
no independent means of generating revenue.  To the extent Antero Midstream Partners has available cash, we intend to cause Antero 
Midstream Partners to make distributions to us in an amount at least sufficient to allow us to pay our taxes, to fund our return of 
capital to our stockholders (including paying dividends and repurchasing shares of our common stock) and for our corporate and other 
overhead expenses.  To the extent that we need funds and Antero Midstream Partners or its subsidiaries are restricted from making 
such distributions or payments under applicable law or regulation or under the terms of any financing arrangements, or are otherwise 
unable to provide such funds, our liquidity and financial condition could be materially adversely affected. 

Taxes 

Our future tax liabilities may be greater than expected if we do not generate deductions or net operating loss (“NOL”) 
carryforwards sufficient to offset taxable income or if tax authorities challenge our tax positions. 

We expect to generate deductions and NOL carryforwards that we can use to offset our taxable income.  As a result, we do 

not expect to pay material U.S. federal and state income taxes through 2026.  This expectation is based upon assumptions our 
management has made regarding, among other things, income, capital expenditures and net working capital.  Further, the IRS or other 
tax authorities could challenge one or more tax positions we take, and any change in law may affect our tax positions.  While we 
expect that our deductions and NOL carryforwards will be available to us as a future benefit, in the event that they are not generated as 
expected, are successfully challenged by the IRS or other tax authorities (in a tax audit or otherwise), or are subject to future 
limitations, our ability to realize these benefits may be limited. 

Changes to applicable tax laws and regulations or exposure to additional income tax liabilities could adversely affect our 
operating results and cash flows. 

We are subject to various complex and evolving U.S. federal, state and local tax laws.  U.S. federal, state and local tax laws, 

policies, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us, in each case, 
possibly with retroactive effect.  Any significant variance in our interpretation of current tax laws or a successful challenge of one or 
more of our tax positions by the IRS or other tax authorities could increase our future tax liabilities and adversely affect our operating 
results and cash flows. 

Taxable gain or loss on the sale of our common stock could be more or less than expected. 

If a holder sells our common stock, the holder will recognize gain or loss equal to the difference between the amount realized 

and the holder’s tax basis in the shares of common stock sold.  To the extent that the amount of distributions on our common stock 
exceeds our current and accumulated earnings and profits, such distributions will be treated as a tax free return of capital and will 
reduce a holder’s tax basis in its common stock.  We expect a portion of our distributions to be in excess of our earnings and profits 
through 2028.  Because our distributions in excess of our earnings and profits decrease a holder’s tax basis in our common stock, such 
excess distributions will result in a corresponding increase in the amount of gain, or a corresponding decrease in the amount of loss, 
recognized by the holder upon the sale of our common stock.   

The IRS Forms 1099-DIV that our stockholders receive from their brokers may over-report dividend income with respect to 
our common stock for U.S. federal income tax purposes, which may result in a stockholder’s overpayment of tax.  In addition, 
failure to report dividend income in a manner consistent with the IRS Forms 1099-DIV may cause the IRS to assert audit 
adjustments to a stockholder’s U.S. federal income tax return.  For non-U.S. holders of our common stock, brokers or other 
withholding agents may overwithhold taxes from dividends paid, in which case a stockholder generally would have to timely 
file a U.S. tax return or an appropriate claim for refund to claim a refund of the overwithheld taxes. 

Distributions we pay with respect to our common stock will constitute “dividends” for U.S. federal income tax purposes only 

to the extent of our current and accumulated earnings and profits.  Distributions we pay in excess of our earnings and profits will not 
be treated as “dividends” for U.S. federal income tax purposes; instead, they will be treated first as a tax-free return of capital to the 
extent of a stockholder’s tax basis in their common stock and then as capital gain realized on the sale or exchange of such stock.  We 
may be unable to timely determine the portion of our distributions that is a “dividend” for U.S. federal income tax purposes, which 
may result in a stockholder’s overpayment of tax with respect to distribution amounts that should have been classified as a tax-free 
return of capital.  In such a case, a stockholder generally would have to timely file an amended U.S. tax return or an appropriate claim 
for refund to obtain a refund of the overpaid tax. 

35

For a U.S. holder of our common stock, the IRS Forms 1099-DIV received from brokers may not be consistent with our 

determination of the amount that constitutes a “dividend” for U.S. federal income tax purposes or a stockholder may receive a 
corrected IRS Form 1099-DIV (and may therefore need to file an amended U.S. federal, state or local income tax return).  We will 
attempt to timely notify our stockholders of available information to assist with income tax reporting (such as posting the correct 
information on our website).  However, the information that we provide to our stockholders may be inconsistent with the amounts 
reported by a broker on IRS Form 1099-DIV, and the IRS may disagree with any such information and may make audit adjustments to 
a stockholder’s tax return. 

For a non-U.S. holder of our common stock, “dividends” for U.S. federal income tax purposes will be subject to withholding 

of U.S. federal income tax at a 30% rate (or such lower rate as may be specified by an applicable income tax treaty) unless the 
dividends are effectively connected with the conduct of a U.S. trade or business.  In the event that we are unable to timely determine 
the portion of our distributions that constitute a “dividend” for U.S. federal income tax purposes, or a stockholder’s broker or 
withholding agent chooses to withhold taxes from distributions in a manner inconsistent with our determination of the amount that 
constitutes a “dividend” for such purposes, a stockholder’s broker or other withholding agent may overwithhold taxes from 
distributions paid.  In such a case, a stockholder generally would have to timely file a U.S. tax return or an appropriate claim for 
refund in order to obtain a refund of the overwithheld tax. 

General Risks 

We expect to use a significant portion of our cash flows to pay dividends to our stockholders and/or repurchase shares of our 
common stock, which could limit our ability to grow and make acquisitions. 

We have previously announced that we plan to return capital to our stockholders through dividends to our stockholders and 

repurchasing shares of our common stock, which may cause our growth to proceed at a slower pace than that of businesses that 
reinvest their cash to expand ongoing operations.  To the extent we issue additional shares of common stock in connection with any 
acquisitions or expansion capital expenditures, the payment of dividends on those additional shares may increase the risk that we will 
be unable to maintain or increase our per share dividend level.  In addition, the incurrence of commercial borrowings or other debt to 
finance our growth strategy would result in increased interest expense, which, in turn, may reduce the cash that we have available to 
return capital to our stockholders through dividends and/or repurchases of shares of our common stock. 

We may reduce or cease paying dividends on our common stock. 

We are not obligated to pay dividends on shares of our common stock.  Subject to preferences that may be applicable to any 

outstanding shares or series of preferred stock, holders of our common stock are only entitled to receive ratably such dividends 
(payable in cash, stock or otherwise), if any, as may be declared from time to time by our Board out of funds legally available for 
dividend payments.  Our Board makes a determination each quarter as to the actual amount, if any, of dividends to pay on our 
common stock, based on various factors, some of which are beyond our control, including our operating cash flows, our working 
capital needs, our ability to access capital markets for debt and equity financing on reasonable terms, the restrictions contained in our 
debt instruments, our debt service requirements, credit metrics and the cost of acquisitions, if any.  We may not have sufficient cash 
each quarter to pay dividends or maintain current or expected levels of dividends.  Accordingly, we cannot guarantee that we will 
declare any future dividends at levels consistent with our historic practice or at all. 

The price of our common stock may be volatile, and you could lose a significant portion of your investment.  

The market price of our common stock could be volatile, and holders of common stock may not be able to resell their 

common stock at or above the price at which they acquired such securities due to fluctuations in the market price of our common 
stock.  

Specific factors that may have a significant effect on the market price for our common stock include: 

• 

• 

• 

• 

our operating and financial performance and prospects and the trading price of our common stock; 

the level of our dividends;  

quarterly variations in the rate of growth of our financial indicators, such as dividends per share of our common stock, 
net income and revenues;  

levels of indebtedness;

There may be future dilution of our common stock, which could adversely affect the market price of shares of our common 
stock.  

We are not restricted from issuing additional shares of our common stock out of our authorized capital.  In the future, we may 

issue shares of our common stock to raise cash for future activities, acquisitions or other purposes.  We may also acquire interests in 
other companies by using a combination of cash and shares of our common stock or only shares.  We may also issue securities 
convertible into, or exchangeable for, or that represent the right to receive, shares of our common stock.  Any of these events may 
dilute the ownership interests of our stockholders, reduce our net income per share or have an adverse effect on the price of shares of 
our common stock.  

Sales of a substantial amount of shares of our common stock in the public market could adversely affect the market price of 
our shares.  

Sales of a substantial amount of shares of our common stock in the public market or grants to our directors and officers under 
the Amended and Restated Antero Midstream Corporation Long Term Incentive Plan (“AM LTIP”), or the perception that these sales 
or grants may occur, could reduce the market price of shares of our common stock.  All of the shares of our common stock are freely 
tradable without restriction or further registration under the Securities Act, unless the shares are held by any of our “affiliates” as such 
term is defined in Rule 144 under the Securities Act.  In addition, we are party to a registration rights agreement with Antero 
Resources, certain members of management and certain funds affiliated with Yorktown, pursuant to which we agreed to register the 
resale of shares of our common stock issued or paid to them in the transactions that occurred pursuant to the Simplification 
Agreement, dated as of October 9, 2018.  We cannot predict the size of future issuances of our common stock or securities convertible 
into our common stock or the effect, if any, that future issuances and sales of shares of our common stock will have on the market 
price of our common stock. 

Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for 
certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders' ability 
to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.  

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court 
of Chancery of the State of Delaware (the “Court of Chancery”) will, to the fullest extent permitted by applicable law, be the sole and 
exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action or proceeding asserting a claim of 
breach of a fiduciary duty owed by any of our current or former directors, officers, stockholders, employees or agents to us or our 
stockholders, (iii) any action or proceeding asserting a claim arising pursuant to any provision of the DGCL, our certificate of 
incorporation or our bylaws as to which the DGCL confers jurisdiction on the Court of Chancery or (iv) any action or proceeding 
asserting a claim against us governed by the internal affairs doctrine, in each such case subject to the Court of Chancery having 
personal jurisdiction over the indispensable parties named as defendants therein.  The foregoing provision does not apply to claims 
under the Securities Act, the Exchange Act or any claim for which the U.S. federal courts have exclusive jurisdiction.  Furthermore, if 
the Court of Chancery lacks subject matter jurisdiction for any such matter, any state or federal court located within Delaware will be 
the sole and exclusive forum for that matter.  Any person or entity purchasing or otherwise acquiring or holding any interest in shares 
of our capital stock will be deemed to have notice of, and consented to, the provisions of certificate of incorporation described in the 

37 

Table of Contents  
preceding sentence.  This choice of forum provision may limit our stockholder’s ability to bring a claim in a judicial forum that it finds 
favorable for disputes with it or its directors, officers, employees or agents, which may discourage such lawsuits against us and such 
persons.  Alternatively, if a court were to find these provisions of our certificate of incorporation inapplicable to, or unenforceable in 
respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such 
matters in other jurisdictions, which could adversely affect our business, financial condition and results of operations. 

We may issue preferred stock, which may have terms that could adversely affect the voting power or value of our common 
stock. 

Our certificate of incorporation authorizes our Board to issue, without the approval of our stockholders, one or more classes 

or series of preferred stock having such designations, preferences, limitations and relative rights, including preferences over our 
common stock respecting dividends and distributions, as our Board may determine.  The terms of one or more classes or series of our 
preferred stock could adversely impact the voting power or value of our common stock.  For example, we might grant holders of a 
class or series of our preferred stock the right to elect some number of our directors in all events or on the happening of specified 
events or the right to veto specified transactions.  Similarly, the repurchase or redemption rights or liquidation preferences we might 
assign to holders of our preferred stock could affect the residual value of our common stock.

ITEM 1C.  CYBERSECURITY 

Processes for Assessing, Identifying and Managing Cybersecurity Risks 

We are continuously assessing and adopting new processes, systems and resources in an effort to make our business safer 

from cybersecurity threats.  We depend on digital technology in many areas of our business and operations, including, but not limited 
to, our gathering and compression and water handling services, processing and recording financial and operating data, oversight and 
analysis of our operations and communications with the employees supporting our operations and our customers and service 
providers.  We also collect and store sensitive data in the ordinary course of our business, including certain personally identifiable 
information and proprietary information for our business and that of our customers, suppliers, investors and other stakeholders.  

Attacks on our assets or security breaches in our systems or infrastructure could lead to the corruption, loss or unauthorized 

use of such data, delays in production or delivery of our production to customers, difficulty in completing and settling transactions, 
challenges in maintaining our books and records, environmental damage, communication interruptions or other operational 
disruptions.  We seek to address these risks by safeguarding assets, data and operations through the cybersecurity risk management 
processes described below: 

Risk Assessments 

We assess our systems, networks and data infrastructure to identify potential cybersecurity threats and vulnerabilities via 
continuous automated processes that are complemented by manual processes that are executed on both a routine and ad hoc basis.  
These processes are designed to prevent, detect and investigate activities and events that could pose a cybersecurity risk or threat to us, 
and include, but are not limited to, monitoring and evaluating cybersecurity intelligence information published or provided by certain 
United States federal government agencies as well as private cybersecurity groups.  Our risk assessment processes are conducted, 
monitored and reviewed by our security and compliance team as well as third-party consultants.  In addition, we perform 
cybersecurity tabletop exercises with our information technology (“IT”) department throughout the year.  We also engage a third-party 
consultant to conduct an annual penetration test of our systems, networks and data infrastructure to complement our risk assessment 
processes and activities.  These risk assessments help evaluate the likelihood and potential impact of cybersecurity incidents. 

Our Vice President – IT oversees these risk assessments and meets regularly with the security and compliance team to review 

cybersecurity risks and threats, and also participates in our enterprise risk management process.  In addition, the Company engages 
several third-party consultants in connection with the risk assessments, and we have established separate processes and procedures to 
oversee and identify cybersecurity risks associated with third parties.  All third parties involved in our cybersecurity risk assessments 
are required to provide reports designed to allow us to monitor and assess such third parties’ security controls. 

38 

Table of Contents  
We monitor and manage our cybersecurity risk and threat exposure through prioritized remediation efforts.  Any 

cybersecurity risk or threat that requires corrective action is managed by our security and compliance team together with certain 
business partners and IT specialists, as deemed necessary.  Potential solutions are assessed in alignment with risk, business and 
cybersecurity priorities and our controls and security architecture.  Plans to remediate cybersecurity risks are approved and monitored 
regularly for completion. 

Incident Identification and Response 

We have implemented a monitoring and detection system, with oversight from our Vice President – IT to help promptly 

identify cybersecurity incidents.  In the event of any breach or cybersecurity incident, we have a formal incident response plan 
designed to provide for immediate action to contain the incident, mitigate the impact and restore normal operations efficiently. 

Cybersecurity Training and Awareness  

We train our users throughout the year using a wide variety of methods on cybersecurity-related topics, including how to 

identify and report potential social engineering including phishing through emails, text messages and phone calls.  Formal training on 
cybersecurity practices begins when an employee is hired and is re-administered annually.  We also require third-party contractors 
with access to our systems be trained on these topics.  In addition, special training is held both formally and informally for groups that 
entail higher threat risks. 

Policies  

Our IT polices are designed to address and manage all aspects of our IT environment, including cybersecurity, and we review 

and update our policies regularly as part of our risk management processes.  We deploy both an internal Protection of Personal 
Identifiable Information Policy and a publicly available Privacy Notice to help us understand and respect the privacy of the individuals 
whose data we have custody over.  We monitor our data collection practices, policies and notices in an effort to comply with the 
evolving nature of applicable data privacy and security laws. 

Our cybersecurity risk management processes are integrated into our enterprise risk management program.  Cybersecurity 
threats are understood to be dynamic and intersect with various other enterprise risks.  As such, cybersecurity is considered to be an 
important component of our enterprise risk management approach.  Our cybersecurity strategies are based on standard cybersecurity 
frameworks, including the National Institute of Standards and Technology and the International Organization for Standardization. 

Board of Directors’ Oversight of Cybersecurity Risks and Management’s Role in Assessing and Responding to Cybersecurity 
Risks 

Cybersecurity risks are overseen at the board level through the Audit Committee.  Our Vice President – IT, together with the 

security and compliance team, is responsible for the monitoring, assessment and management of cybersecurity risk, and seeks to 
maintain the security and continuity of our operations.  Our Vice President – IT oversees the Company’s cybersecurity strategy, 
cybersecurity and data privacy policies, measures and controls, and Board of Directors and Audit Committee communications on 
cybersecurity matters.  Our Vice President – IT regularly briefs senior management, the Board of Directors and the Audit Committee 
on cybersecurity issues as part of our overall enterprise risk management program, including quarterly updates to the Audit 
Committee, which may include information regarding our exposure to privacy and cybersecurity risks, plans and activities to monitor 
and mitigate privacy and cybersecurity risks, IT governance policies and programs, including our cybersecurity incident response 
plan, and legislative and regulatory developments that could impact our privacy and cybersecurity risks.  Additionally, our Vice 
President – Risk Management oversees our enterprise risk management process and apprises the Audit Committee and our Board of 
Directors of all significant risks facing the Company, including cybersecurity risks. 

Our Vice President – IT, Biren Kumar, has more than 17 years of experience serving as a Chief Information Officer (“CIO”) 

or similar role, which included responsibility for managing cybersecurity risk.  Mr. Kumar was named Vice President – IT in 2024.  
Prior to joining Antero, he served as the CIO for several companies, including Dynegy Inc. from 2005 to 2011, Rockwater Energy 
Solutions Inc. from 2011 to 2014, KLX Inc. from 2014 to 2018 and KLX Energy Services Holdings, Inc. from 2018 to 2021.  Mr. 
Kumar holds a Bachelor of Business Administration in Management Information Systems and a Master of Business Administration 
from the University of Houston. 

Impact of Risks from Cybersecurity Threats 

The energy industry’s growing reliance on information technology and operational technology to support critical operations, 
such as energy distribution and management activities, has made it more susceptible to cybersecurity incidents.  As a result, the global 

39 

Table of Contents  
rise of cybersecurity incidents, whether from intentional attacks or accidental events, poses a significant challenge to our industry.  As 
cybersecurity threats continue to evolve in complexity and scale, it remains an ongoing and increasingly difficult task for the industry 
to prevent, detect, mitigate, and remediate these incidents. 

As of the date of this Annual Report on Form 10-K, we are not aware of any cybersecurity threats, including as a result of 

any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us.  However, we 
acknowledge that cybersecurity threats are continually evolving, and the possibility of future discovery of cybersecurity incidents 
remains.  Please see “Item 1A. Risk Factors” for additional information about cybersecurity risks.  Despite the implementation of our 
cybersecurity programs, our security measures cannot guarantee that a cyberattack with significant impact will not occur.  A 
successful attack on our IT systems could have significant consequences to the business.  While we devote resources to our security 
measures to protect our systems and information, these measures cannot provide absolute security.  See “Item 1A. Risk Factors” for 
additional information about the risks to our business associated with a breach or compromise to our information technology systems. 

ITEM 3.  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.

Dividends 

On January 14, 2026, the Board declared an aggregate cash dividend on the shares of our common stock of $0.2250 per share 

for the quarter ended December 31, 2025.  The dividend was paid on February 11, 2026 to stockholders of record as of January 28, 
2026. 

The Board also declared a cash dividend of $137,500 on shares of our Series A Non-Voting Perpetual Preferred Stock, par 

value $0.01 (the “Series A Preferred Stock”), that will be paid on February 17, 2026 in accordance with the terms of the Series A 
Preferred Stock, which are discussed in Note 13—Equity and Net Income Per Common Share to our consolidated financial statements.  
As of December 31, 2025, there were dividends in the amount of $68,750 accumulated in arrears on our Series A Preferred Stock. 

The amount and timing of future payment of cash dividends on our common stock, if any, is within the discretion of the 

Board and will depend on our earnings, capital requirements, financial condition and other relevant factors. 

Share Repurchase Program 

On February 13, 2024, our Board of Directors authorized a share repurchase program that allows us to repurchase up to 
$500 million of shares of our outstanding common stock.  During the year ended December 31, 2025, we repurchased and retired 
approximately 8 million shares of our common stock through our share repurchase program for a total cost of $135 million.  As of 
December 31, 2025, there was $336 million remaining 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.  The 1% U.S. federal excise tax on certain repurchases 
of stock by publicly traded U.S. corporations enacted as part of the IRA 2022 applies to our share repurchase program. 

Stock Performance Graph 

The graph below shows the cumulative total shareholder return assuming the investment of $100 on December 31, 2020 in 
(i) our common stock (assuming reinvestment of dividends), (ii) the Standard & Poor’s 500 (“S&P 500”) Index and (iii) the Alerian 
Midstream Energy (“AMNA”) Index.  We believe the AMNA Index is meaningful because it is an independent, objective view of the 
performance of similarly-sized midstream energy companies.

ITEM 7.  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 consolidated financial statements and related notes included elsewhere in this report.  The information provided below 
supplements, but does not form part of, our 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. 

Overview 

We are a growth-oriented midstream energy company formed to own, operate and develop midstream energy assets to 

primarily service Antero Resources’ production and completion activity.  We believe that our strategically located assets and our 
relationship with Antero Resources have allowed us to become a leading midstream energy company serving the Appalachian Basin 
and present opportunities to expand our midstream services to other operators in the Appalachian Basin.  Our assets consist of 
gathering pipelines, 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 two independent water handling systems that deliver 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 includes 
gathering pipelines and integrated water handling assets in the core of the Marcellus Shale in West Virginia.  Pursuant to the same 
agreement, Antero Resources agreed to acquire 100% of the issued and outstanding equity interests of HG Production for total cash 
consideration of $2.8 billion, subject to the terms and conditions thereof.  The HG Upstream Acquisition includes approximately 
385,000 net acres in the core of the Marcellus Shale in West Virginia.  These acquisitions closed on February 3, 2026.  The HG 
Acquisition was funded with net proceeds of the 2034 Notes (as defined below), borrowing under the Credit Facility and restricted 
cash.  See Note 3—Transactions to our consolidated financial statements for additional information.  We intend to make certain 
modifications to our existing commercial arrangements with Antero Resources to provide for on-pad compression with respect to 
certain wells and to provide a transition period through 2026 before certain water services would be provided under the existing 
agreements with Antero Resources. 

Utica Shale Divestiture 

On December 5, 2025, we entered into the Utica Shale PSA 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 includes 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 is 
expected to close in February 2026, subject to the satisfaction of certain customary closing conditions.  The net proceeds from the 
Utica Shale Divestiture are expected to be used for the repayment of long-term debt.  See Note 3—Transactions to our consolidated 
financial statements for additional information.

Senior Notes 

Issuance of 2033 Notes 

On September 22, 2025, we issued $650 million in aggregate principal amount of 5.75% senior notes due October 15, 2033 
(the “2033 Notes”) at par.  The 2033 Notes are unsecured and effectively subordinated to the Credit Facility to the extent of the value 
of the collateral securing the Credit Facility.  The 2033 Notes rank pari passu to our other outstanding senior notes and are guaranteed 
on a full and unconditional and joint and several senior unsecured basis by our wholly owned subsidiaries and certain of our future 
restricted subsidiaries.  The net proceeds from this offering were used to redeem the 2027 Notes.  See Note 9—Long-Term Debt to our 
consolidated financial statements for additional information. 

Issuance of 2034 Notes 

On December 23, 2025, we issued $600 million in aggregate principal amount of 5.75% senior notes due July 1, 2034 (the 

“2034 Notes”).  The 2034 Notes are unsecured and effectively subordinated to the Credit Facility to the extent of the value of the 
collateral securing the Credit Facility.  The 2034 Notes rank pari passu to our other outstanding senior notes and are guaranteed on a 
full and unconditional and joint and several senior unsecured basis by our wholly owned subsidiaries and certain of our future 
restricted subsidiaries.  The net proceeds from this offering were used to partially fund the HG Acquisition.  See Note 3—Transactions 
and Note 9—Long-Term Debt to our consolidated financial statements for additional information. 

Redemption of 2027 Notes 

During the year ended December 31, 2025, we redeemed $650 million aggregate principal amount of our 5.75% senior notes 

due March 1, 2027 (the “2027 Notes”) at par, plus accrued and unpaid interest.  The 2027 Notes were retired as of September 23, 
2025.  See Note 9—Long-Term Debt to our consolidated financial statements for additional information. 

Share Repurchase Program 

Through our share repurchase program, during the year ended December 31, 2025, we repurchased and retired approximately 
8 million shares of our common stock for a total cost of $135 million.  As of December 31, 2025, we have approximately $336 million 
of capacity remaining 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 and ethane increased significantly, while benchmark prices for C3+ NGL’s and oil 
decreased during the year ended December 31, 2025 as compared to the year ended December 31, 2024.  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 2024.  In order to manage the inflation risk present in the United States’ 
economy, the Federal Reserve utilized monetary policy in the form of interest rate increases beginning in 2022 in an effort to bring the 
inflation rate in line with its stated goal of 2% on a long-term basis.  Between 2022 and 2023, the Federal Reserve increased the 
federal funds interest rate by 5.25%.  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.  While inflationary pressures in the 
United States’ economy have begun to subside, it is uncertain what impact recent tariff activity by the United States and foreign 
governments will have on inflation. 

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, Iran 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. 

Sources of Our Revenues 

The following items are the primary components of our revenues: 

•  Gathering and Processing.  Our low pressure gathering, compression and high pressure gathering services support 
production operations for Antero Resources.  Our gathering and processing revenues are driven by the volumes of 
natural gas we gather and compress.  We receive a low pressure gathering fee per Mcf, a compression fee per Mcf and a 
high pressure gathering fee per Mcf, as applicable, substantially all of which are subject to annual CPI-based 
adjustments.  Additionally, our gathering and compression agreements provide for certain minimum volume 
commitments for gathering and compression services that run to 2035.  Pursuant to our long-term contracts with Antero 
Resources, we have secured long-term dedications covering substantially all of Antero Resources’ current and future 
acreage for gathering and compression services.  Our gathering and compression operations are substantially dependent 
upon natural gas production from Antero Resources’ upstream activity in its areas of operation.  In addition, there is a 
natural decline in production from existing wells that are connected to our gathering systems.  Although we expect that 
Antero Resources will continue to devote substantial resources to the development of oil and gas reserves, we have no 
control over this activity and Antero Resources has the ability to reduce or curtail such development at its discretion.  
See Note 6—Revenue to our consolidated financial statements for additional information on our gathering and 
compression agreements. 

•  Water Handling.  Our fresh water delivery systems and other fluid handling services support well completion and 

production operations for Antero Resources.  These services are provided by us directly or through third-parties with 
which we contract.  Our water handling revenues are driven by quantities of fresh water delivered to our customers to 
support their well completion operations and produced water transported, blended and/or disposed.  We receive a fixed 
fee for all fresh water deliveries by pipeline directly to the well site, subject to annual CPI-based adjustments.  Our other 
fluid handling services include wastewater handling, blending and high-rate transfer services.  For other fluid handling 
services provided by us, we charge Antero Resources a cost of service fee.  For other fluid handling services provided by 
third parties, we charge Antero Resources a fee based on our third-party out-of-pocket costs plus 3%.  We have a long-
term water services agreement covering Antero Resources’ approximately 566,000 gross acres in West Virginia and 
Ohio, with a right of first offer on all future areas of operation.  The initial term of the water services agreement runs to 
2035.  Our water handling operations are substantially dependent upon the number of wells drilled and completed by 
Antero Resources, as well as Antero Resources’ production.  As of December 31, 2025, Antero Resources had disclosed 
estimated net proved reserves of 19.1 Tcfe, of which 61% was natural gas, 38% were NGLs and 1% was oil.  Antero 
Resources’ has a vast drilling inventory of horizontal well locations in the Appalachian Basin, all of which are on 
acreage dedicated to us, providing us with significant opportunity for future capital investments as Antero Resources’ 
drilling program continues.  See Note 6—Revenue to our consolidated financial statements for additional information on 
our water services agreement.

Principal Components of Our Cost Structure  

The following items are the primary components of our operating expenses: 

•  Direct Operating.  We seek to maximize the profitability of our operations in part by minimizing, to the extent 

appropriate, expenses directly tied to operating and maintaining our assets.  We schedule and conduct preventative 
maintenance over time to avoid significant variability in our direct operating expense and minimize the impact on our 
cash flow.  Gathering and compression operating costs consist primarily of labor, water disposal, pigging, fuel, 
monitoring, repair and maintenance, utilities and contract services.  Gathering and compression operating costs vary with 
the miles of pipeline and number of compressor stations in our gathering and compression system.  Fresh water operating 
expenses consist primarily of labor, pigging, monitoring, repair and maintenance and contract services.  Fresh water 
operating costs vary with the miles of pipeline, number of pumping stations and number of well completions in the 
Appalachian Basin for which we deliver fresh water and number of impoundments in our water system.  Other fluid 
handling costs relate to contract services performed by us and third parties.  Our other fluid handling costs consist of 
labor, monitoring and repair and maintenance costs.  The other primary drivers of our direct operating expense include 
maintenance and contract services, regulatory and compliance expense and ad valorem taxes. 

•  General and Administrative.  Our general and administrative expenses include direct charges incurred by us and costs 

charged by Antero Resources.  These costs relate to: (i) various business services, including payroll processing, accounts 
payable processing and facilities management, (ii) various corporate services, including legal, accounting, treasury, 
information technology and human resources and (iii) compensation, including certain equity-based compensation.  
These expenses are charged to the Company based on 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.  Management believes these allocation methodologies are reasonable.  Equity-based compensation 
includes costs related to the AM LTIP. 

•  Depreciation.  Depreciation consists of our estimate of the decrease in value of the assets capitalized in property and 
equipment as a result of using the assets throughout the applicable year.  Depreciation is computed over the asset’s 
estimated useful life using the straight-line basis.  See Note 7—Property and Equipment to our consolidated financial 
statements for additional information on our asset classes and estimated lives of our assets. 

• 

• 

• 

Impairment.  We evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the 
related carrying values of the assets may not be recoverable.  If the carrying values of the assets are deemed not 
recoverable, the carrying values are reduced to their estimated fair value. 

Interest.  We have typically financed a portion of our cash requirements with borrowings under our Credit Facility and 
with senior unsecured notes.  Our interest expense also includes amortization of deferred financing costs incurred in 
connection with our Credit Facility and senior notes and amortization of senior notes premiums.  See Note 9—Long-
Term Debt to our consolidated financial statements for additional information on our debt agreements. 

Income tax expense.  We are subject to state and U.S. federal income taxes but are currently not in a material cash tax 
paying position with respect to state and U.S. federal income taxes.  The difference between our financial statement 
income tax expense and our current U.S. federal income tax liability is primarily due to the differences in the tax and 
financial statement treatment of our investment in Antero Midstream Partners.  We have recorded deferred income tax 
expense to the extent our deferred income tax liabilities exceed our deferred income tax assets.  Our deferred income tax 
assets result primarily from net operating loss carryforwards.  As of December 31, 2025, we had U.S. federal NOL 
carryforwards of $557 million and state NOL carryforwards of $406 million.  The Company currently considers all of its 
deferred income tax assets, except for those related to charitable contributions, realizable.  The amount of deferred 
income tax assets considered realizable, however, could change as we generate taxable income or as estimates of future 
taxable income are reduced.  See Note 8—Income Taxes to our consolidated financial statements for additional 
information on our deferred income tax position and income tax expense.

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 compressor stations that collect and process production from Antero 
Resources’ wells in the Appalachian Basin, as well as equity in earnings from our investments in the Joint Venture 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) two independent systems that deliver 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 consolidated financial statements for 
additional information.

Revenues.  Total revenues increased by 7%, from $1.1 billion for the year ended December 31, 2024, to $1.2 billion for the 
year ended December 31, 2025.  Total revenues included amortization of customer relationships of $71 million for each of the years 
ended December 31, 2024 and 2025.  Gathering and processing revenues increased by 7%, from $889 million for the year ended 
December 31, 2024 to $950 million for the year ended December 31, 2025.  Water handling revenues increased by 10%, from 
$217 million for the year ended December 31, 2024 to $238 million for the year ended December 31, 2025.  These fluctuations 
primarily resulted from the following: 

Gathering and Processing 

•  Low pressure gathering revenue increased $24 million period over period primarily due to increased throughput volumes of 
48 Bcf, or 141 MMcf/d, and increased low pressure gathering rates as a result of annual CPI-based adjustments.  Low 
pressure gathering volumes increased between periods primarily due to 78 additional wells being connected to our system 
since December 31, 2024, partially offset by natural production decline of the wells connected to our system between 
periods. 

•  Compression revenue increased $16 million period over period primarily due to increased throughput volumes of 50 Bcf, 
or 146 MMcf/d, and increased compression rates as a result of annual CPI-based adjustments.  Compression volumes 
increased between periods primarily due to 78 additional wells being connected to our system since December 31, 2024, 
partially offset by natural production decline of the wells connected to our system between periods. 

•  High pressure gathering revenue increased $21 million period over period primarily due to increased throughput volumes 
of 55 Bcf, or 160 MMcf/d, and increased high pressure gathering rates as a result of annual CPI-based adjustments.  High 
pressure gathering volumes increased between periods primarily due to 78 additional wells being connected to our system 
since December 31, 2024, partially offset by natural production decline of the wells connected to our system between 
periods.

Water Handling 

•  Fresh water delivery revenue increased $5 million period over period primarily due to increased fresh water delivery 
volumes of 1 MMBbl, or 2 MBbl/d, and an increase to the fresh water delivery rate as a result of an annual CPI-based 
adjustment.  Fresh water delivery volumes increased between periods due to the increase in wells serviced by our fresh 
water delivery system as a result of the timing of well completions by Antero Resources. 

•  Other fluid handling services revenue increased $16 million period over period primarily due to increased other fluid 

handling volumes of 1 MMBbl, or 3 MBbl/d, as a result of higher wastewater trucking and blending volumes, as well as 
higher costs that are billed at cost plus 3% and blending cost of service fees between periods. 

Direct operating expenses.  Direct operating expenses increased by 6%, from $218 million for the year ended December 31, 

2024 to $232 million for the year ended December 31, 2025.  Gathering and processing direct operating expenses increased by 5% 
from $103 million for the year ended December 31, 2024 to $108 million for the year ended December 31, 2025 primarily due to 
increased gathering and compression volumes, higher costs for the two compressor stations and 48 miles of high pressure gathering 
lines acquired during the second quarter of 2024 and increased heavy maintenance expense between periods.  Water handling direct 
operating expenses increased by 8%, from $115 million for the year ended December 31, 2024 to $124 million for the year ended 
December 31, 2025 primarily due to increased other fluid handling volumes, higher wastewater trucking and disposal costs, and 
increased blending costs between periods.  

General and administrative (excluding equity-based compensation) expenses.  General and administrative expenses 
(excluding equity-based compensation expense) remained consistent at $42 million for the year ended December 31, 2024 and 2025, 
respectively. 

Equity-based compensation expenses.  Equity-based compensation expenses remained relatively consistent at $44 million and 

$46 million for the year ended December 31, 2024 and 2025, respectively.  See Note 11—Equity-Based Compensation to our 
consolidated financial statements for additional information. 

Depreciation expense.  Depreciation expense decreased by 4%, from $140 million for the year ended December 31, 2024 to 

$134 million for the year ended December 31, 2025 primarily due to lower depreciation expense of $11 million related to our program 
to repurpose underutilized compressor units to expand existing or construct new compressor stations between periods, partially offset 
by depreciation expense of $4 million related to assets placed in service between periods and higher depreciation expense of $1 
million for our assets acquired during the second quarter of 2024. 

Loss on long-lived assets.  During the year ended December 31, 2025, we recognized a loss on long-lived assets of $87 

million related to the write-down of our Utica Shale net assets held for sale to the cash consideration expected to be received in the 
Utica Shale Divestiture less costs to sell.  There was no loss on long-lived assets during the year ended December 31, 2024.  See Note 
3—Transactions to our consolidated financial statements for additional information. 

Interest expense.  Interest expense decreased by 8%, from $207 million for the year ended December 31, 2024 to $190 

million for the year ended December 31, 2025 primarily due to lower interest expense on our senior notes due to the repurchase and 
redemption of the 7.875% senior notes due May 15, 2026 (the “2026 Notes”) during the year ended December 31, 2024, and the 
redemption of the 2027 Notes during the year ended December 31, 2025, as well as lower interest rates on our Credit Facility between 
periods, partially offset by the issuances of the 6.625% senior notes due February 1, 2032 (the “2032 Notes”), 2033 Notes and 2034 
Notes and higher average borrowing on our Credit Facility between periods.  See Note 9—Long-Term Debt to our consolidated 
financial statements for additional information. 

Equity in earnings of unconsolidated affiliates.  Equity in earnings in unconsolidated affiliates increased by 5%, from 
$111 million for the year ended December 31, 2024 to $116 million for the year ended December 31, 2025 primarily due to increased 
processing volumes and higher processing and fractionation fees as a result of annual CPI-based adjustments between periods. 

Loss on early extinguishment of debt.  During the year ended December 31, 2024, we recognized a loss on early 

extinguishment of debt of $14 million related to the premium paid to repurchase or otherwise fully redeem all of our 2026 Notes at a 
weighted average premium of 101.975% of the principal amount thereof, plus accrued and unpaid interest, as well as the write-off of 
unamortized deferred financing costs.  During the year ended December 31, 2025, we recognized a loss on early extinguishment of 
debt of $1 million related to the write-off of unamortized deferred financing costs and premium attributable to our 2027 Notes that 
were fully redeemed at par, plus accrued and unpaid interest.  See Note 9—Long-Term Debt to our consolidated financial statements 
for additional information.

Transaction expense.  During the year ended December 31, 2025, we incurred $5 million of transaction expense related to the 

HG Acquisition.  There were no transaction expenses during the year ended December 31, 2024.  See Note 3—Transactions to our 
consolidated financial statements for additional information. 

Income tax expense.  Income tax expense increased by 2%, from $148 million for the year ended December 31, 2024 to 

$151 million for the year ended December 31, 2025, which reflects effective tax rates of 26.9% and 26.8%, respectively.  This income 
tax expense increase was primarily due to higher income before income taxes between periods.  See Note 8—Income Taxes to our 
consolidated financial statement for additional information.  

Year Ended December 31, 2023 Compared to Year Ended December 31, 2024 

See “Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations —Results of 

Operations” in our 2024 Annual Report on Form 10-K for a discussion of the results of operations for the year ended December 31, 
2023 compared to the year ended December 31, 2024.   

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, our 

Utica Shale Divestiture and capital market transactions.  See Note 3—Transactions and Note 9—Long-Term Debt to our consolidated 
financial statements for additional information.  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. 

During the year ended December 31, 2025, we paid dividends of $0.90 per share, or a total of $439 million, to holders of our 

common stock, as applicable, and we paid $550,000 of dividends on our Series A Preferred Stock.  On January 14, 2026, the Board 
declared a cash dividend on the shares of our common stock of $0.2250 per share for the quarter ended December 31, 2025.  The 
dividend was paid on February 11, 2026 to stockholders of record as of January 28, 2026.  Our Board also declared a cash dividend of 
$137,500 on our Series A Preferred Stock that will be paid on February 17, 2026 in accordance with their terms.  As of December 31, 
2025, there were dividends in the amount of $68,750 accumulated in arrears on our Series A Preferred Stock.  See Note 12—Cash 
Dividends and Note 13—Equity and Net Income Per Common Share to our consolidated financial statements for additional 
information. 

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, the net proceeds from the 
offering of the 2034 Notes, proceeds from our Utica Shale Divestiture and borrowings under the Credit Facility. 

As of December 31, 2025, we did not have any off-balance sheet arrangements.  

Cash Flows

Operating activities.  Net cash provided by operating activities was $844 million and $932 million for the years ended 

December 31, 2024 and 2025, respectively.  This increase in cash flows provided by operating activities between periods was 
primarily due to higher gathering and processing and water handling revenues and changes in working capital, partially offset by 
increased direct operating expenses between periods.

Investing activities.  Net cash flows used in investing activities was $243 million and $169 million for the years ended 
December 31, 2024 and 2025, respectively.  The decrease in cash flows used in investing activities between periods was primarily due 
to our acquisition of gathering and compression assets during the second quarter of 2024 of $70 million, before closing adjustments, 
and lower capital spending related to our gathering systems and facilities of $50 million, partially offset by higher capital spending on 
our water handling systems of $40 million and additional investment in Stonewall of $4 million between periods.  The decreased 
capital spending for our gathering systems and facilities is primarily due to decreased high pressure pipeline projects of 7 miles in 
West Virginia.  The increased capital spending for our water handling systems is primarily due to increased surface pipeline projects 
of 8 miles in West Virginia. 

Financing activities.  Net cash used in financing activities was $601 million and $500 million for the years ended 

December 31, 2024 and 2025, respectively.  The decrease in cash flows used in financing activities between periods was primarily due 
to the issuance of our 2034 Notes of $600 million for the HG Acquisition, partially offset by increased net repayments on our Credit 
Facility of $339 million, increased repurchases of common stock of $106 million, lower cash provided from the refinancing of our 
2026 Notes with our 2032 Notes of $39 million and higher employee tax withholdings for the settlement of equity-based 
compensation awards of $13 million.

year ended December 31, 2023 compared to the year ended December 31, 2024.

On February 11, 2026, we announced a 2026 capital budget with a range of $190 million to $220 million.  Our capital budget 
reflects the closing of the HG Acquisition on February 3, 2026 and assumes the closing of the Utica Shale Divestiture during February 
2026.  Our capital budgets may be adjusted as business conditions warrant.  We routinely monitor and adjust our capital expenditures 
in response to changes in Antero Resources’ development plans, changes in prices, availability of financing, acquisition costs, industry 
conditions, the timing of regulatory approvals, success or lack of success in Antero Resources’ drilling activities, contractual 
obligations, internally generated cash flows and other factors both within and outside our control.  Additionally, we monitor our 
existing assets and look for opportunities to reuse or otherwise repurpose assets in an effort to optimize our capital efficiency. 

Debt Agreements  

We may, from time to time, seek to retire or purchase our outstanding debt through cash purchases, open market purchases, 

privately negotiated transactions or otherwise.  Any such repurchases will depend on prevailing market conditions, our liquidity 
requirements, contractual restrictions and other factors.  We were in compliance with all covenants and ratios applicable to our debt 
agreements as of December 31, 2024 and 2025.  The amounts involved could be material.  See Note 9—Long-Term Debt to our 
consolidated financial statements for additional information. 

Critical Accounting Estimates  

The discussion and analysis of our financial condition and results of operations are based upon our financial statements, 

which have been prepared in accordance with GAAP.  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 
consolidated financial statements.  The preparation of our 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 

51 

Table of Contents  
 
 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
be reasonable under the circumstances, the results of which form the basis for making judgments about the reported amounts in our 
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 financial statements. 

Property and Equipment 

Property and equipment primarily consists of gathering pipelines, compressor stations and the water handling assets.  We 

evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the related carrying values of the 
assets may not be recoverable.  Generally, the basis for making such assessments is undiscounted future cash flow projections for the 
assets being assessed.  If the carrying values of the assets are deemed not recoverable, the carrying values are reduced to the estimated 
fair values, which are calculated using the expected present value of future cash flows method.  Significant assumptions used in the 
cash flow forecasts include future net operating margins, future volumes, discount rates and future capital requirements. 

Determination of depreciation expense requires judgment regarding the estimated useful lives and salvage values of property 
and equipment.  Uncertainties that may impact these estimates of useful lives include, among others, changes in laws and regulations 
relating to environmental matters, including air and water quality, restoration and abandonment requirements, economic conditions 
and supply and demand for the Company’s services in the areas in which it operate.  Historically, we have not experienced material 
changes in our results of operations from revisions to the estimated useful lives or salvage values of our property and equipment.  
However, these estimates are reviewed periodically and can be subject to revision as circumstances warrant.  We believe that the 
estimates and assumptions related to depreciation expense are critical because the assumptions used to estimate useful lives and 
salvage values of property and equipment are susceptible to change as circumstances warrant.  These assumptions affect depreciation 
expense and, if changed, could have a material effect on the Company's results of operations and financial position. 

Income Taxes 

Income taxes are accounted for using the asset and liability approach.  Under this approach, deferred income tax assets and 

liabilities are recognized based on anticipated future tax consequences attributable to differences between financial statement carrying 
amounts of assets and liabilities and their respective tax basis.  We record deferred income tax expense to the extent our deferred 
income tax liabilities exceed our deferred income tax assets.  We record a deferred income tax benefit to the extent our deferred 
income tax assets exceed our deferred income tax liabilities.  We are subject to state and U.S. federal income taxes, but are currently 
not in a cash tax paying position with respect to U.S. federal income taxes.  

We record a valuation allowance when we believe all or a portion of our deferred income tax assets will not be realized.  In 

assessing the realizability of our deferred income tax assets, management considers whether some portion or all of the deferred income 
tax assets will be realized based on a more-likely-than-not standard of judgment.  The ultimate realization of deferred income tax 
assets is dependent upon our ability to generate future taxable income during the periods in which our deferred income tax assets are 
deductible.  Management considers the scheduled reversal of deferred income tax liabilities, projected future taxable income and tax 
planning strategies in making this assessment, estimates of which may be imprecise due to unforeseen future events or conditions 
outside of our control, including changes in Antero Resources’ production or development plans or changes to tax laws and 
regulations.  The amount of deferred income tax assets considered realizable could change based upon the amounts of taxable income 
actually generated, or as estimates of future taxable income change.   

The calculation of deferred income tax assets and liabilities involves uncertainties in the application of complex tax laws and 

regulations.  We recognize in our financial statements those tax positions which we believe are more-likely-than-not to be sustained 
upon examination by the IRS or state revenue authorities.  We believe that the estimates and assumptions related to income taxes are 
critical because the assumptions and estimates required to assess the likelihood that our deferred income tax assets will be recovered 
from future taxable income, as well as the amount and timing of a valuation allowance on our deferred income tax assets is an exercise 
in judgement and susceptible to change as circumstances warrant.  These assumptions affect deferred income tax liability and income 
tax expense and, if changed, could have a material effect on the Company's financial position and results of operations. 

ITEM 7A.  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.  

52 

Table of Contents  
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 December 31, 2025, we had no outstanding 
borrowings or letters of credit under the Credit Facility.  A 1.0% increase in the Credit Facility interest rate would have resulted in an 
estimated $5 million increase in interest expense for the year ended December 31, 2025. 

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 9A.  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 annual report.  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 December 31, 2025 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 December 31, 2025 that have materially affected, or are reasonably likely to 
materially affect, our internal control over financial reporting.    

Management’s Annual Report on Internal Control Over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for us as 

defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act.  This system is designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting 
principles generally accepted in the United States of America. 

Our internal control over financial reporting includes those policies and procedures that: 

(i)  pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and 

dispositions of the assets; 

(ii)  provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in 
accordance with authorizations of our management and directors; and 

(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of 

our assets that could have a material effect on the financial statements. 

Because of its inherent limitations, a system of internal control over financial reporting can provide only reasonable 

assurance and may not prevent or detect all misstatements.  Further, because of changes in conditions, effectiveness of internal 
controls over financial reporting may vary over time. 

Under the supervision of, and with the participation of our management, including the Chief Executive Officer and Chief 

Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 
framework and criteria established in Internal Control—Integrated Framework in 2013, issued by the Committee of Sponsoring 
Organizations of the Treadway Commission.  Based on this evaluation, our management concluded that our internal control over 
financial reporting was effective as of December 31, 2025. 

The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by KPMG LLP, 

an independent registered public accounting firm, as stated in their report which appears on page F-2 in this Annual Report on 
Form 10-K.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and the Board of Directors 
Antero Midstream Corporation: 

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting  

We have audited the accompanying consolidated balance sheets of Antero Midstream Corporation and subsidiaries (the Company) as 
of December 31, 2024 and 2025, the related consolidated statements of operations and comprehensive income, stockholders’ equity, 
and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the 
consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 31, 
2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of 
the Company as of December 31, 2024 and 2025, and the results of its operations and its cash flows for each of the years in the three-
year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.  Also in our opinion, the 
Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025 based on 
criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission. 

Basis for Opinions  

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over 
financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the 
accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion 
on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based 
on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) 
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits 
to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to 
error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. 

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the 
consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well 
as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting 
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and 
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included 
performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable 
basis for our opinions. 

Definition and Limitations of Internal Control Over Financial Reporting  

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles.  A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the 
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect 
on the financial statements. 

F-2 

Table of Contents  
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements 
that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are 
material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a 
whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or 
on the accounts or disclosures to which it relates. 

Evaluation of impairment triggering events for long-lived assets 

As discussed in Note 2 to the consolidated financial statements, the Company evaluates property and equipment (collectively, 
long-lived assets) for impairment whenever events or changes in circumstances indicate that the related carrying values may not 
be recoverable (triggering events). The carrying value of property and equipment as of December 31, 2025 was $3.5 billion.  

We identified the evaluation of impairment triggering events for long-lived assets as a critical audit matter.  A higher degree of 
subjective auditor judgment was required to assess whether events or changes in circumstances indicate carrying values may not 
be recoverable.  

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested 
the operating effectiveness of an internal control related to the long-lived assets impairment process. This included a control 
related to the Company’s process to identify and assess impairment triggering events for long-lived assets and the underlying 
quantitative data used to perform the analysis. We evaluated the Company’s identification of impairment triggering events for 
long-lived assets and responses to the factors considered by: 

• 

• 

• 

• 

evaluating overall macro-economic conditions 

analyzing historical financial results for long-lived assets to identify significant degradations in the related cash flows 

evaluating the minimum volume commitments with Antero Resources Corporation and their impact on the recoverability of 
the long-lived assets 

examining external information on certain of the Company’s customers’ drilling plans to assess continued development. 

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

ANTERO MIDSTREAM CORPORATION 
Notes to Consolidated Financial Statements 

(1)  Organization 

Antero Midstream Corporation together with its consolidated subsidiaries (the “Company” or “Antero Midstream”), is a 

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

The Company’s gathering and processing assets consist of high and low pressure gathering pipelines, compressor stations 

and processing and fractionation plants that collect and process natural gas and NGLs from Antero Resources’ wells in the 
Appalachian Basin.  The Company’s water handling assets include two independent systems that deliver water from sources including 
the Ohio River, local reservoirs and several regional waterways, which portions of these systems are also utilized to transport 
flowback and produced water.  The Company’s water handling assets also include other flowback and produced water treatment 
facilities. 

Antero Midstream also has a 50% equity interest in the Joint Venture and a 15% equity interest in a gathering system of 

Stonewall.  See Note 15—Investments in Unconsolidated Affiliates.  

(2)  Summary of Significant Accounting Policies 

(a)  Basis of Presentation 

The accompanying consolidated financial statements have been prepared in accordance with GAAP.  In the opinion of 

management, these consolidated financial statements include all adjustments (consisting of normal and recurring accruals) considered 
necessary to present fairly the Company’s financial position as of December 31, 2024 and 2025, and the results of the Company’s 
operations and its cash flows for the years ended December 31, 2023, 2024 and 2025.  The Company has no items of other 
comprehensive income; 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 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 consolidated financial statements (see 

Note 5—Transactions with Affiliates). 

(b)  Principles of Consolidation 

The accompanying 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 consolidated 
financial statements. 

Investments in entities for which the Company exercises significant influence, but not control, are accounted for under the 

equity method.  The Company’s judgment regarding the level of influence over its equity investments includes considering key factors 
such as Antero Midstream’s ownership interest, representation on the Board of Directors and participation in the policy-making 
decisions of equity method investees.  Such investments are included in Investments in unconsolidated affiliates on the Company’s 
consolidated balance sheets.  Income from investees that are accounted for under the equity method is included in Equity in earnings 
of unconsolidated affiliates on the Company’s consolidated statements of operations and comprehensive income and cash flows.  
When the Company records its proportionate share of net income, it increases equity income in the statements of operations and 
comprehensive income and the carrying value of that investment on the Company’s balance sheet.  When a distribution is received, it 
is recorded as a reduction to the carrying value of that investment on the balance sheet. 

F-8 

Table of Contents ANTERO MIDSTREAM CORPORATION 
Notes to Consolidated Financial Statements (Continued) 

The Company accounts for distributions received from equity method investees under the “nature of the distribution” 

approach.  Under this approach, distributions received from equity method investees are classified on the basis of the nature of the 
activity or activities of the investee that generated the distribution as either a return on investment (classified as cash inflows from 
operating activities) or a return of investment (classified as cash inflows from investing activities). 

(c)  Use of Estimates 

The preparation of the consolidated financial statements and notes in conformity with GAAP requires that management 

formulate estimates and assumptions that affect revenues, expenses, assets, liabilities and the disclosure of contingent liabilities.  Items 
subject to estimates and assumptions include the useful lives of property and equipment, evaluating impairments of long-lived and 
intangible assets, as well as the valuation of accrued liabilities and deferred and current income taxes, among others.  Although 
management believes these estimates are reasonable, actual results could differ from these estimates. 

(d)  Cash and Cash Equivalents 

The Company considers all liquid investments purchased with an initial maturity of three months or less to be cash 

equivalents.  The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these 
instruments.  From time to time, the Company may be in the position of a “book overdraft” in which outstanding checks exceed cash 
and cash equivalents.  The Company classifies book overdrafts in accounts payable within its consolidated balance sheets, and 
classifies the change in accounts payable associated with book overdrafts as an operating activity within its consolidated statements of 
cash flows. 

(e)  Restricted Cash 

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

(f)  Property and Equipment 

Property and equipment primarily consists of (i) gathering pipelines, (ii) compressor stations, (iii) the wastewater treatment 
facility (the “Clearwater Facility”), (iv) other flowback and produced water facilities and (v) water handling pipelines and facilities 
stated at historical cost less accumulated depreciation, amortization and impairment.  The Company capitalizes construction-related 
direct labor and material costs.  Maintenance and repair costs are expensed as incurred. 

Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives and 
salvage values of assets.  The depreciation of fixed assets recorded under operating lease agreements is included in depreciation 
expense.  Uncertainties that may impact these estimates of useful lives include, among others, changes in laws and regulations relating 
to environmental matters, including air and water quality, restoration and abandonment requirements, economic conditions and supply 
and demand for the Company’s services in the areas in which it operates.  When assets are placed into service, management makes 
estimates with respect to useful lives and salvage values that management believes are reasonable.  The Company reviews the 
estimated useful lives of its assets to determine if any changes are necessary as circumstances warrant. 

The Company evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the 

related carrying values of the assets may not be recoverable.  Generally, the basis for making such assessments is undiscounted future 
cash flow projections for the assets being assessed.  If the carrying values of the assets are deemed not recoverable, the carrying values 
are reduced to the estimated fair values, which are based on discounted future cash flows using assumptions as to revenues, costs and 
discount rates typical of third-party market participants, which is a Level 3 fair value measurement. 

During the year ended December 31, 2024, the Company acquired certain Marcellus Shale gas gathering and compression 

assets.  This transaction was accounted for as asset acquisition in accordance with FASB ASC Topic 805-50, Business Combinations, 
Related Issues (“ASC 805-50”).  Accordingly, the acquired assets were recorded based upon the cash consideration paid, with all 
value assigned to Property and equipment in the consolidated balance sheets.  See Note 3— Transactions for additional information.

(g)  Investments in Unconsolidated Affiliates 

The Company uses the equity method of accounting to account for its investments in the Joint Venture and Stonewall.  The 

Company uses the equity method to account for its investments in companies if the investment provides the Company with the ability 
to exercise significant influence over, but not control of, the operating and financial policies of the investee.  The Company’s 
judgment regarding the level of influence over each equity method investee includes considering key factors such as the Company’s 
ownership interest, representation on the board of directors, participation in policy-making decisions of the investee and material 
intercompany transactions.  Such investments are included in the investments in unconsolidated affiliates on the Company’s 
consolidated balance sheets. 

Income (loss) from investees that are accounted for under the equity method is included in equity in earnings (loss) of 

unconsolidated affiliates on the Company’s consolidated statements of operations and comprehensive income and cash flows.  When 
the Company records its proportionate share of net income (loss), it is recorded to equity in earnings (loss) of unconsolidated affiliates 
in the consolidated statements of operations and comprehensive income and the carrying value of that investment on its consolidated 
balance sheet.  Distributions received from equity method investees are recorded as reductions to the carrying value of the investment 
on the consolidated balance sheet.  The Company’s equity in earnings (loss) of unconsolidated affiliates is adjusted for basis 
differences recognized due to the difference between the cost of the equity method investment and the amount of underlying equity in 
the net assets as of March 12, 2019.  Basis differences are amortized into equity in earnings (loss) of unconsolidated affiliate on the 
Company’s consolidated statements of operations and comprehensive income over the remaining useful lives of the underlying assets 
and liabilities. 

The Company accounts for distributions received from equity method investees under the “nature of the distribution” 

approach.  Under this approach, distributions received from equity method investees are classified on the basis of the nature of the 
activity or activities of the investee that generated the distribution as either a return on investment (classified as cash provided by 
operating activities) or a return of investment (classified as cash provided by investing activities).   

(h)  Intangible Assets 

Amortization of intangible assets with definite lives is calculated using the straight-line method, which is reflective of the 

benefit pattern in which the estimated economic benefit is expected to be received over the estimated useful life of the intangible asset.  
Intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the 
carrying amount of the intangible asset may not be recoverable.  If the sum of the expected undiscounted future cash flows related to 
the asset is less than the carrying amount of the asset, an impairment loss is recognized based on the fair value of the asset. 

(i)  Income Taxes 

The Company recognizes deferred income tax assets and liabilities for temporary differences resulting from net operating 

loss and charitable contribution carryforwards and the differences between the financial statement and tax basis of assets and 
liabilities.  The effect of changes in tax laws or tax rates is recognized in income during the period such changes are enacted.  Deferred 
income tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some 
portion, or all, of the deferred income tax assets will not be realized.  The Company regularly reviews its tax positions in each 
significant taxing jurisdiction during the process of evaluating its tax provision.  The Company makes adjustments to its tax provision 
when: (i) facts and circumstances regarding a tax position change, causing a change in management’s judgment regarding that tax 
position; and/or (ii) a tax position is effectively settled with a tax authority at a differing amount. 

On July 4, 2025, Public Law No. 119-21, commonly referred to as the One Big Beautiful Bill Act, was enacted.  The OBBB 
contains a broad range of changes to U.S. federal income tax laws and makes permanent or modifies certain provisions of Public Law 
No. 115-97, commonly referred to as the Tax Cuts and Jobs Act.  These changes include, among others, permanently restoring an 
earnings before interest, taxes, depreciation and amortization based business interest deduction limitation, 100% bonus depreciation 
for certain property and immediate expensing for certain domestic research and experimental expenditures.  All effects of changes in 
tax laws are recognized in the consolidated financial statements during the period of enactment.  As such, the effects of the OBBB are 
reflected in the Company's provision for income taxes as of and for the year ended December 31, 2025.  The OBBB did not have a 
material effect on income tax expense for the year ended December 31, 2025, and the Company expects a refund of substantially all of 
the cash paid for income taxes during the year ended December 31, 2025 when it files its 2025 U.S. federal income tax return as a 
result of the OBBB.

(j)  Asset Retirement Obligations 

The Company’s asset retirement obligations include its obligation to close, maintain and monitor landfill cells and support 

facilities.  After the landfill is certified closed, the Company must continue to maintain and monitor the landfill for a post-closure 
period, which generally extends for 30 years.  The Company records the fair value of its landfill retirement obligations as a liability in 
the period in which the regulatory obligation to retire a specific asset is triggered.  For the Company’s individual landfill cells, the 
required closure and post-closure obligations under the terms of its permits and its intended operation of the landfill cell are triggered 
and recorded when the cell is placed into service and salt is initially disposed in the landfill cell.  The fair value is based on the total 
estimated costs to close the landfill cell and perform post-closure activities once the landfill cell has reached capacity and is no longer 
accepting salt.  Retirement obligations are increased each year to reflect the passage of time by accreting the balance at the weighted 
average credit-adjusted risk-free rate that is used to calculate the recorded liability, with accretion charged to direct costs.  Actual cash 
expenditures to perform closure and post-closure activities reduce the retirement obligation liabilities as incurred.  After initial 
measurement, asset retirement obligations are adjusted at the end of each period to reflect changes, if any, in the estimated future cash 
flows underlying the obligation.  Landfill retirement assets are capitalized as the related retirement obligations are incurred, and are 
amortized on a units-of-consumption basis as the disposal capacity is consumed.  During the year ended December 31, 2021, the 
Company commenced closure and reclamation operations on the landfill, and such closure and reclamation operations were 
substantially complete as of December 31, 2024. 

Asset retirement obligations are recorded for water impoundments and wastewater pits when an abandonment date is 
identified.  The Company records the fair value of its water impoundment and wastewater pit retirement obligations as liabilities in the 
period in which the regulatory obligation to retire a specific asset is triggered.  The fair value is based on the total reclamation costs of 
the assets.  Retirement obligations are increased each year to reflect the passage of time by accreting the balance at the weighted 
average credit-adjusted risk-free rate that is used to calculate the recorded liability, with accretion charged to direct costs.  Actual cash 
expenditures to perform remediation activities reduce the retirement obligation liabilities as incurred.  After initial measurement, asset 
retirement obligations are adjusted at the end of each period to reflect changes, if any, in the estimated future cash flows underlying 
the obligation.  Water impoundments and wastewater pit retirement assets are capitalized as the related retirement obligations are 
incurred, and are amortized on a straight-line basis until reclamation. 

The Company (i) is under no legal obligations, neither contractually nor under the doctrine of promissory estoppel, to restore 

or dismantle its gathering pipelines, compressor stations, water delivery pipelines, flowback and produced water facilities and the 
Clearwater Facility upon abandonment or (ii) intends to operate and maintain its assets as long as supply and demand for natural gas 
exists, which the Company expects to continue into the foreseeable future. 

(k)  Litigation and Other Contingencies 

A liability is recorded for a loss contingency when its occurrence is probable and damages can be reasonably estimated based 
on the anticipated most likely outcome or the minimum amount within a range of possible outcomes.  The Company regularly reviews 
contingencies to determine the adequacy of its accruals and related disclosures.  The ultimate amount of losses, if any, may differ from 
these estimates.  Any contingency that could result in a gain is recorded when realized. 

The Company accrues losses associated with environmental obligations when such losses are probable and can be reasonably 

estimated.  Accruals for estimated environmental losses are recognized no later than at the time a remediation feasibility study or an 
evaluation of response options, is complete.  These accruals are adjusted as additional information becomes available or as 
circumstances change.  Future environmental expenditures are not discounted to their present value.  Recoveries of environmental 
costs from other parties are recorded separately as assets at their undiscounted value when receipt of such recoveries is probable. 

As of December 31, 2024 and 2025, the Company had not recorded any liabilities for litigation, environmental or other 

contingencies. 

(l)  Dividends 

Preferred and common dividends declared are recorded as a reduction of retained earnings to the extent that retained earnings 

were available at the close of the quarter prior to the dividend declaration date, with any excess recorded as a reduction of additional 
paid-in capital.

Notes to Consolidated Financial Statements (Continued) 

(m)  Treasury Share Retirement 

The Company periodically retires treasury shares acquired through share repurchases and returns those shares to the status of 
authorized but unissued.  When treasury shares are retired, the Company’s policy is to allocate the excess of the repurchase price over 
the par value of shares acquired first, to additional paid-in capital, and then to retained earnings.  The portion allocable to additional 
paid-in capital is determined by applying a percentage, determined by dividing the number of shares to be retired by the number of 
shares outstanding, to the balance of additional paid-in capital as of retirement.  

(n)  Revenue Recognition 

The Company provides gathering, compression and water handling services under fee-based contracts primarily based on 

throughput or at cost plus a margin.  Certain of these contracts contain operating leases of the Company’s assets under GAAP.  Under 
these arrangements, the Company receives fees for gathering, compression and water handling services.  The revenue the Company 
earns from these arrangements is directly related to (i) in the case of natural gas gathering and compression, the volumes of metered 
natural gas that it gathers, compresses and delivers to natural gas compression sites or other transmission delivery points, (ii) in the 
case of fresh water services, the quantities of fresh water delivered to its customers for use in their well completion operations, (iii) in 
the case of other fluid handling services provided by third parties, the third-party costs the Company incurs plus 3% or (iv) in the case 
of other fluid handling services performed by the Company, a cost of service fee based on the costs incurred by the Company.  The 
Company recognizes revenue when it satisfies a performance obligation by delivering a service to a customer or the use of leased 
assets to a customer.  The Company includes lease revenue within revenues by service.  See Note 6—Revenue. 

(o)  Equity-Based Compensation 

The Company recognizes compensation cost related to all equity-based awards in the financial statements based on the 

estimated grant date fair value.  The Company’s equity-based compensation expense is included in general and administrative 
expenses, and recorded as a credit to additional paid-in capital.  The Company is authorized to grant various types of equity-based 
compensation awards, including stock options, stock appreciation rights, restricted stock awards, restricted stock unit (“RSU”) awards, 
dividend equivalent awards and other types of awards.  The grant date fair values of such awards are determined based on the type of 
award and may utilize market prices on the date of grant, Black-Scholes option-pricing model, Monte Carlo simulations or other 
acceptable valuation methodologies, as appropriate for the type of equity-based award.  Compensation cost is recognized ratably over 
the applicable vesting or service period.  Forfeitures are accounted for as they occur by reversing the expense previously recognized 
for awards that were forfeited during the period.  See Note 11—Equity-Based Compensation. 

(p)  Fair Value Measures 

The FASB ASC Topic 820, Fair Value Measurements and Disclosures, clarifies the definition of fair value, establishes a 

framework for measuring fair value and expands disclosures about fair value measurements.  This guidance also relates to all 
nonfinancial assets and liabilities that are not recognized or disclosed on a recurring basis (e.g., the initial recognition of asset 
retirement obligations and impairments of long-lived assets).  The fair value is the price that the Company estimates would be 
received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  A 
fair value hierarchy is used to prioritize inputs to valuation techniques used to estimate fair value.  An asset or liability subject to the 
fair value requirements is categorized within the hierarchy based on the lowest level of input that is significant to the fair value 
measurement.  The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety 
requires judgment and considers factors specific to the asset or liability.  The highest priority (Level 1) is given to unadjusted quoted 
market prices in active markets for identical assets or liabilities, and the lowest priority (Level 3) is given to unobservable inputs.  
Level 2 inputs are data, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or 
indirectly.  See Note 14—Fair Value Measurement. 

(q)  Recently Adopted or Issued Accounting Standards 

Reportable Segments 

In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosures (“ASU 2023-

07”).  ASU 2023-07 is intended to improve reportable segment disclosures primarily through enhanced disclosure of reportable 
segment expenses.  This ASU is effective for annual reporting periods beginning after December 15, 2023, and interim periods within 
fiscal years beginning after December 15, 2024.  The Company adopted ASU 2023-07 in the 2024 Form 10-K, and it did not have a 
material impact on the Company’s consolidated financial statements.

Income Taxes 

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”).  ASU 
2023-09 is intended to improve income tax disclosures primarily through enhanced disclosure of income tax rate reconciliation items, 
and disaggregation of income (loss) from continuing operations, income tax (expense) benefit and income taxes paid, net disclosures 
by federal, state and foreign jurisdictions, among others.  This ASU is effective for annual reporting periods beginning after 
December 15, 2024.  ASU 2023-09 should be applied on a prospective basis, although retrospective application is permitted.  The 
Company adopted ASU 2023-09 retrospectively in this Annual Report on Form 10-K, and it did not have a material impact on the 
Company’s consolidated financial statements. 

Disaggregation of Income Statement Expenses 

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)   Summit Asset Acquisition 

On May 1, 2024, the Company acquired certain Marcellus Shale gas gathering and compression assets from Summit for $70 

million in cash, before closing adjustments, with an effective date of April 1, 2024.  The acquired assets include 48 miles of high 
pressure gathering pipelines and two compressor stations with 100 MMcf/d of compression capacity.  These assets were already 
interconnected to the Company’s low pressure and high pressure gas gathering systems at the time of acquisition and service Antero 
Resources’ production.  Substantially all of the cash consideration for this asset acquisition was allocated to gathering systems and 
facilities, included in property and equipment, net in the consolidated balance sheets. 

(b)   HG Acquisition 

On December 5, 2025, 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 Midstream for cash consideration of $1.1 
billion, subject to the terms and conditions thereof.  The HG Acquisition includes gathering pipelines and integrated water handling 
assets in the core of the Marcellus Shale in West Virginia.  Pursuant to the same agreement, Antero Resources agreed to acquire 100% 
of the issued and outstanding equity interests of HG Production for total cash consideration of $2.8 billion, subject to the terms and 
conditions thereof.  The HG Upstream Acquisition includes approximately 385,000 net acres in the core of the Marcellus Shale in 
West Virginia.  In connection with the Company’s entry into the definitive agreement relating to the HG Acquisition, the Company 
and Antero Resources agreed to allocate between the parties certain benefits and costs under the agreement and the buyer-side 
representations and warranties insurance policies.  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 is classified as restricted 
cash on the Company’s consolidated balance sheets as of December 31, 2025.  These acquisitions closed on February 3, 2026, with 
effective dates of January 1, 2026.  The Company intends to make certain modifications to its existing commercial arrangements with 
Antero Resources to provide for on-pad compression with respect to certain wells and to provide a transition period through 2026 
before certain water services would be provided under the existing agreements with Antero Resources. 

The disclosure of certain financial information required by FASB ASC Topic 805, Business Combinations, has been omitted 

as it is impracticable to provide such information due to the timing of the closing of the HG Acquisition and issuance of the 
Company’s consolidated financial statements.

(c)   Utica Shale Divestiture 

On December 5, 2025, certain wholly-owned subsidiaries of the Company entered into the Utica Shale PSA with the Buyer 

Parties to sell the Utica Shale Property and Equipment, for aggregate cash consideration of $400 million, subject to the terms and 
conditions thereof.  The Utica Shale Property and Equipment includes 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 is expected to close in February 2026, with an effective date of July 1, 2025, subject to the satisfaction of certain 
customary closing conditions. 

The Utica Shale Property and Equipment and its associated assets and liabilities have been classified as held for sale as of 

December 31, 2025 on the Company’s consolidated balance sheets, 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 expected to be received for the Utica Shale Divestiture less costs to sell was less than its carrying 

value of the Utica Shale Property and Equipment’s net assets as of December 5, 2025.  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. 

The carrying value of the Utica Shale Property and Equipment’s assets and liabilities held for sale were as follows:

Substantially all revenues earned during the years ended December 31, 2023, 2024 and 2025 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.  

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

Accounts receivable—Antero Resources represents amounts due from Antero Resources, primarily related to gathering and 

compression services and water handling services.  Accounts payable—Antero Resources represents amounts due to Antero Resources 
for general and administrative and other costs.  

(c)  Allocation of Costs Charged by Antero Resources 

The employees supporting the Company’s operations are concurrently employed by Antero Resources and the 

Company.  Direct operating expense includes costs charged to the Company of $18 million, $20 million and $21 million during the 
years ended December 31, 2023, 2024 and 2025, respectively.  These costs were for services provided by employees associated with 
the operation of the Company’s gathering lines, compressor stations and water handling assets.  For the years ended December 31, 
2023, 2024 and 2025, general and administrative expense includes costs charged to the Company by Antero Resources of $29 million, 
$32 million and $33 million, respectively.  These costs relate to: (i) various business services, including payroll processing, accounts 
payable processing and facilities management, (ii) various corporate services, including legal, accounting, treasury, information 
technology and human resources and (iii) compensation.  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. 

(a)  Gathering and Compression 

The Company’s gathering and compression service agreements with Antero Resources include: (i) the 2019 gathering and 
compression agreement, (ii) the Marcellus gathering and compression agreement, (iii) the Utica compression agreement and (iv) the 
Mountaineer 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 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, and the Utica 
compression agreement has one remaining acreage dedication that expires in 2030.  Upon expiration of the Marcellus gathering and 
compression agreement, the Utica 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 is terminated, 
effective upon an anniversary of the effective date of the agreement, by notice from either the Company or Antero Resources to the 
other party on or before the 180th day prior to the anniversary of such agreement.  The Utica compression agreement is included in the 
Utica Shale Divestiture. 

The 2019 gathering and compression agreement included a growth incentive fee program whereby low pressure gathering 

fees were reduced from 2020 through 2023 to the extent Antero Resources achieved certain quarterly volumetric targets during such 
time.  Only Antero Resources’ throughput gathered under the 2019 gathering and compression agreement was considered in low 
pressure gathering volume targets.  For the year ended December 31, 2023, Antero Resources earned a fee rebate of $52 million.  The 
growth incentive fee rebate program expired on December 31, 2023. 

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 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, 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 low pressure lines, high pressure lines and/or compressor stations, the 2019 gathering and compression 
agreement contains options at the Company’s election for either (i) minimum volume commitments that require Antero Resources to 
utilize or pay for 75% of the high pressure gathering capacity and 70% of the compression capacity of such new construction for 10 
years or (ii) a cost of service fee that allows the Company to earn a 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 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.  As of December 31, 2025, 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 low pressure volumes are delivered to a 
compressor station, compression volumes are delivered to a high pressure line and high pressure volumes are delivered to a processing 
plant or transmission pipeline, as applicable.  Minimum volume commitments 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 and are determined on 
a monthly basis for each 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.

(b)  Water Handling 

The Company is party to a water services agreement with Antero Resources, whereby the Company provides certain water 
handling services to Antero Resources within an area of dedication in defined service areas in West Virginia and Ohio.  The initial 
term of the water services agreement runs to 2035.  Upon completion of the initial term in 2035, the water services agreement will 
continue in effect from year to year until such time as the agreement is terminated, effective upon an anniversary of the effective date 
of the agreement, by notice from either the Company or Antero Resources to the other party on or before the 180th 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 December 31, 2025, the Company had minimum future revenues for its cost of service fees of $67 
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. 

The Company satisfies its performance obligations and recognizes revenue when (i) the fresh water volumes have been 

delivered to the hydration unit of a specified well pad or (ii) other fluid handling services have been completed.  The Company 
invoices the customer the month after water services are performed, and payment is due in the same month.  For services contracted 
through third-party providers, the Company’s performance obligation is satisfied when the service to be performed by the third-party 
provider has been completed.  The Company invoices the customer after the third-party provider billing is received, and payment is 
due in the same month. 

Transaction Price Allocated to Remaining Performance Obligations 

The Company’s water service agreement with Antero Resources has a term greater than one year.  The Company is not 
required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated 
entirely to a wholly unsatisfied performance obligation.  Under this contract, each unit of product delivered to the customer represents 
a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to 
remaining performance obligations is not required. 

The Company also performs water services for third-party customers and such contracts are short-term in nature with a 

contract term of one year or less.  Accordingly, the Company is exempt from disclosure of the transaction price allocated to remaining 
performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less.

Contract Balances 

Under the Company’s water service contracts, the Company invoices customers after the performance obligations have been 

satisfied, at which point payment is unconditional.  Accordingly, the Company’s water service contracts do not give rise to contract 
assets or liabilities.

In assessing the realizability of the deferred income tax assets, management considers whether some portion or all of the 

deferred income tax assets will be realized based on a more-likely-than-not standard of judgment.  The ultimate realization of deferred 
income tax assets is dependent upon the generation of future taxable income during the periods in which the Company’s temporary 
differences become deductible.  Management considers projected future taxable income and tax planning strategies in making this 
assessment.  Based upon the projections of future taxable income over the periods in which the deferred income tax assets are 
deductible, management believed that the Company will not realize the benefits of certain of these deductible differences related to 
charitable contributions.  As such, as of December 31, 2024 and 2025, the Company recorded a full valuation allowance for its 
charitable contributions. 

The calculation of the Company’s tax assets and liabilities involves uncertainties in the application of complex tax laws and 
regulations.  The Company gives financial statement recognition to those tax positions that it believes are more-likely-than-not to be 
sustained upon examination by the IRS or state revenue authorities.  As of December 31, 2024 and 2025, the Company did not have 
any uncertain tax positions. 

As of December 31, 2025, the Company has U.S. federal and state NOL carryforwards before the effect of income taxes of 

$557 million and $406 million, respectively, which have no expiration date.  Tax years 2022 through 2025 remain open to 
examination by the IRS.  The Company and its subsidiaries file tax returns with various state taxing authorities, and those returns 
remain open to examination for tax years 2021 through 2025.

On July 30, 2024, Antero Midstream Partners, an indirect, wholly owned subsidiary of Antero Midstream Corporation, as 

borrower (the “Borrower”), amended and restated its senior secured revolving credit facility with a syndicate of banks.  Lender 
commitments under the Credit Facility were $1.25 billion as of December 31, 2024 and 2025, 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 December 31, 2025, the Credit Facility had an available borrowing capacity of $1.25 billion. 

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, 2024 and 

2025.

The Credit Facility provides for borrowing under either the Adjusted Term 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%.  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

the sale or other disposition does not violate the covenants set forth in the indentures governing the applicable Senior Notes.

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 years ended December 31, 2023, 2024 and 2025, all of the Company’s assets and operations are attributable to the

(c)  Performance Share Unit Awards 

Performance Share Unit Awards Based on Return on Invested Capital   

In April 2022, the Company granted performance share units (“PSUs”) to certain of its employees and executive officers that 
vest based on the Company’s actual return on invested capital (“ROIC”) (as defined in the award agreement) over a three-year period 
concluding on December 31, 2024 as compared to a targeted ROIC (“2022 ROIC PSUs”).  The number of shares of the Company’s 
common stock that can be earned with respect to the 2022 ROIC PSUs ranges from zero to 200% of the target number of 2022 ROIC 
PSUs originally granted.  The performance condition for the 2022 ROIC PSUs was met at 200% of target as of December 31, 2024.  
As a result, during the first quarter of 2025 the 2022 ROIC PSUs vested and converted into approximately 0.9 million shares of the 
Company’s common stock.  As of December 31, 2025, there were no 2022 ROIC PSUs outstanding. 

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 will vest and convert into approximately one million shares of the Company’s common stock. 

In March 2024, 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, 2026 as compared to a targeted ROIC 
(“2024 ROIC PSUs”).  The number of shares of the Company’s common stock that can be earned with respect to the 2024 ROIC 
PSUs ranges from zero to 200% of the target number of 2024 ROIC PSUs originally granted.  The likelihood of achieving the 
performance conditions related to 2024 ROIC PSUs was probable as of December 31, 2025. 

In March 2025, 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, 2027 as compared to a targeted ROIC 
(“2025 ROIC PSUs”).  The number of shares of the Company’s common stock that can be earned with respect to the 2025 ROIC 
PSUs ranges from zero to 200% of the target number of 2025 ROIC PSUs originally granted.  The likelihood of achieving the 
performance conditions related to 2025 ROIC PSU awards was probable as of December 31, 2025. 

Summary Information for Performance Share Unit Awards 

PSU awards vest subject to the satisfaction of certain performance and service requirements.  Expense related to each PSU 

award is recognized on a straight-line basis over the performance period of the entire award.  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 PSU awards 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 grant date fair value per share for PSUs granted during the years ended December 31, 2023, 
2024 and 2025 were $10.58, $13.44 and $16.46, respectively.

(13)  Equity and Net Income Per Common Share 

(a)  Preferred Stock 

The Board authorized 100,000,000 shares of preferred stock on March 12, 2019, and issued 10,000 shares of preferred stock 
designated as "5.5% Series A Non-Voting Perpetual Preferred Stock" (the "Series A Preferred Stock"), to The Antero Foundation on 
that date.  Dividends on the Series A Preferred Stock are cumulative from the date of original issue and payable in cash on the 45th 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 years ended December 31, 2023, 2024 and 2025. 

(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.

(14)  Fair Value Measurement 

The carrying values on the 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, 2024 and 2025 approximated fair value because the 
variable interest rates are reflective of current market conditions. 

The fair value and carrying value of the Company’s Senior Notes is as follows:

The Company used an income approach to estimate the selling price less costs to sell of the Utica Shale Property and 

Equipment, which represents fair value of the Utica Shale Property and Equipment as of December 31, 2025.  The selling price less 
costs to sell is based on significant inputs not observable in the market, and therefore, represents a Level 3 measurement within the fair 
value hierarchy.  See Note 3—Transactions for additional information. 

(15)  Investments in Unconsolidated Affiliates 

(a)  Summary of Investments in Unconsolidated Affiliates  

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

The Company also has a 15% equity interest in a gathering system of Stonewall, which operates a 67-mile pipeline on which 

Antero Resources is an anchor shipper.

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

Clearwater Facility.  

On March 13, 2020, 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.

Notes to Consolidated Financial Statements (Continued) 

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 in 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 certiorari with 
respect to the December 19, 2024 decision by the Colorado Court of Appeals.  Veolia and Antero Treatment have each submitted their 
principal merits briefs to the Colorado Supreme Court, and Veolia’s reply brief is due on March 5, 2026.  Oral argument has not yet 
been scheduled. 

(17)  Reportable Segments 

The Company’s operations, which are located in the United States, are organized into two reportable segments: (i) gathering 
and processing and (ii) water handling.  These segments are monitored separately by management for performance and are consistent 
with internal financial reporting.  These segments have been identified based on the differing products and services (including the 
expertise required for these operations), production processes and distribution methods.  The Company’s Chief Executive Officer and 
President was determined to be the Company’s chief operating decision maker (“CODM”).  The CODM evaluates the performance of 
the Company’s business segments based on operating income.  The CODM considered the Company’s actual operating income as 
compared to the operating income for (i) the relevant prior period actual results, (ii) budget and (iii) guidance on a monthly basis for 
purposes of evaluating performance of each segment and making decisions about allocating capital and other resources to each 
segment.  Interest expense is primarily managed and evaluated on a consolidated basis.  Accounting policies for each segment are the 
same as the Company’s accounting policies described in Note 2—Summary of Significant Accounting Policies to the consolidated 
financial statements. 

(a)  Summary of Reportable Segments 

Gathering and Processing 

The gathering and processing segment includes a network of gathering pipelines and compressor stations that collect and 
process production from Antero Resources’ wells in West Virginia and Ohio.  The gathering and processing segment also includes 
equity in earnings from the Company’s investments in the Joint Venture and Stonewall. 

Water Handling 

The Company’s water handling segment includes two independent systems that deliver water from sources including the 

Ohio River, local reservoirs and several regional waterways.  Portions of these water handling systems are also utilized to transport 
flowback and produced water.  The water handling systems consist of permanent buried pipelines, surface pipelines and water storage 
facilities, as well as pumping stations, blending facilities and impoundments to transport water throughout the systems used to deliver 
water for well completions.
