DEAR 
FELLOW 
SHARE-
HOLDERS

As we celebrate our 10th year of operations since our Initial Public Offering in 2014, 
Antero Midstream has never been in a stronger position. In 2023, Antero Midstream 
reported a record-breaking year both operationally and financially. As the demand for 
cleaner, lower-cost, and reliable energy increased across the world, Antero Midstream’s 
operations delivered. Our highly integrated assets efficiently transported company record 
volumes of natural gas to domestic consumers for natural gas power generation as well 
as internationally through liquified natural gas (“LNG”) and Liquified Petroleum Gas 
(“LPG”) export facilities. Over the next two years, a second wave of LNG export facilities 
is expected to increase U.S. exports by 40%, or 6 Billion Cubic Feet (“Bcf”) per day. This 
significant demand growth emphasizes the need for capital efficient midstream companies 
such as Antero Midstream to safely supply this growing demand as the critical first link to 
delivering U.S. natural gas across the globe.

A DECADE OF OPERATIONAL SUCCESS

Antero Midstream gathered a company record 3.3 
Bcf/d of natural gas in 2023, an 11% increase year-
over-year. This was driven by our organic investments 
as well as the successful integration of our two highly 
strategic, bolt-on acquisitions in the Marcellus and 
Utica Shales. Our 3.3 Bcf/d of gathering volumes 
represents approximately 3% of all of the natural gas 
transported in the United States, highlighting Antero 
Midstream’s growing scale in the natural gas market.

BALANCE SHEET RESILIENCE

As we entered the year, Antero Midstream was 
committed to transitioning the business model to 
generate consistent and repeatable Free Cash Flow 
after dividends. We exceeded our initial expectations 
by over 40%, which allowed us to reduce our total 
debt by approximately $150 million and our leverage 
to just 3.3 times Net Debt to Adjusted EBITDA. As we 
look ahead, we expect continued debt and leverage 
reduction in order to further de-risk our business.  
Our balance sheet strength and flexible capital 
budgets are a unique combination that positions us 
well for growth opportunities and continues delivering 
value for our shareholders.

PEER LEADING RETURNS ON 
INVESTED CAPITAL

Antero Midstream’s capital investments declined 
by 30% in 2023 as we leveraged our existing 
infrastructure to drive throughput and earnings growth. 
This highly visible and efficient capital investment 
strategy, combined with attractive economics, 

generated a corporate-wide 18% return on invested 
capital, or “ROIC”. As we look ahead to 2024, we 
expect further capital reductions while still generating 
peer-leading ROIC. This return on invested capital 
supports returns of capital to shareholders in the  
form of an attractive dividend and share repurchases 
under our recently announced $500 million share 
repurchase program.

LEADERS IN OUR COMMUNITIES

In keeping with our commitment to our local 
communities and furthering education, Antero 
announced a $4,000,000 gift to West Virginia 
University to support undergraduate and graduate 
students in Petroleum and Natural Gas Engineering. 
We also established an Antero Professorship, and 
helped develop a new Master’s Degree program in 
Petroleum Midstream Engineering. This midstream 
engineering program will be the first of its kind in the 
United States. In addition, we maintained our excellent 
track record of peer-leading safety performance, and 
are on track to meet our goal of reducing 100% of our 
pipeline maintenance emissions by the end of 2025.

LOOKING AHEAD

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.

Paul M. Rady
Chairman, CEO & President

in their entirety by this cautionary statement.  This cautionary statement should also be considered in connection with any subsequent 
written or oral forward-looking statements that we or persons acting on our behalf may issue. 

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements to reflect 

events or circumstances after the date of this Annual Report on Form 10-K. 

iv 

 
 
 
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. 

• 

Increasing attention to ESG 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. 

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 

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

results of operations. 

Acquisitions and Takeovers 

•  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. 

•  Certain of our stockholders have investments in our affiliates that may conflict with the interests of other stockholders. 

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 change 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 29.0% ownership interest in us as of December 31, 2023.  

Business Strategy and Competitive Strengths 

Scalable 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 deliver returns on capital and grow the business in a capital efficient manner. 

Additionally, we own a 50% equity interest in the Joint Venture to develop processing and fractionation assets in Appalachia 

and a 15% equity interest in the Stonewall gas gathering system.  These investments provide us with greater exposure to the 
midstream value chain. 

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 returns on invested capital.  We believe this just-in-time 
capital budgeting approach is unique to Antero Midstream and allows us to generate sustainable free cash flow. 

Fixed Fee Business with Long-Term Customer Contracts 

We provide gathering, compression, processing, fractionation and integrated water services, including fresh water delivery 
services and other fluid handling services, to Antero Resources under long-term, fixed-fee and cost of service fee contracts, 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.  Both our 2019 gathering and compression agreement (as defined below in “—Our 
Relationship with Antero Resources—Operational and Managerial Arrangements with Antero Resources”) and water service 
agreement are subject to automatic annual renewal with rights by either party to terminate on or before the 180th day prior to the 
effective date of such automatic renewal.  Additionally, Antero Resources has (i) dedicated to us all of its current and future acreage in 
the Appalachian Basin for gathering and compression services and all of its acreage within defined service areas in the Appalachian 
Basin for water services, subject to any pre-existing dedications or other third-party commitments, and (ii) granted us certain rights of 
first offer with respect to gathering, compression, processing and fractionation services and water services for acreage located outside 
of the existing dedicated areas under our existing agreements.  See “—Our Relationship with Antero Resources” for further 
information. 

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 energy company to service Antero Resources and the other operators in the Appalachian Basin. 

Culture of Continuous Improvement and Responsible Stewardship 

We are committed to a culture of continuous improvement, which serves as our foundation to develop and achieve our ESG 

goals as well as further our goal of environmental stewardship.  Innovation, collaboration, technology and establishing meaningful 
goals have enabled us to improve our safety record, recycle or reuse a substantial majority of Antero Resources’ produced and 
flowback water and further our commitment to lowering GHG emissions intensity across our operations.  We believe natural gas is 

1 

 
key to the energy transition because of its ability to provide energy security to developing nations and replace more GHG-intensive

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 16—Reportable Segments to our 
consolidated financial statements. 

Acquisitions 

On October 25, 2022, we acquired certain Marcellus gas gathering and compression assets from Crestwood Equity Partners 

LP (NYSE: CEQP) (“Crestwood”) for $205 million in cash, before closing adjustments.  These assets included 72 miles of dry gas 
gathering pipelines and nine compressor stations with approximately 700 MMcf/d of compression capacity.  The throughput of these 
acquired assets was approximately 200 MMcf/d at the time of acquisition, resulting in significant available capacity for growth. 

Additionally, on December 21, 2022, we acquired certain Utica compression assets from EnLink Midstream LLC (NYSE: 

ENLC) (“EnLink”) for $10 million in cash, before closing adjustments.  These assets included four compressor stations with 
approximately 380 MMcf/d of compression capacity.  The acquired compression assets are interconnected with the Company’s 
existing low pressure and high pressure gathering systems and service Antero Resources’ production.  The throughput of these assets 
was approximately 100 MMcf/d at the time of acquisition.  See Note 6—Property and Equipment to the consolidated financial 
statements for more information on our asset acquisitions. 

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, 2023, we added 17 miles of low pressure pipeline, 6 miles of buried water pipeline and 

9 miles of surface water pipeline in the Appalachian Basin.  In addition, our compression capacity declined by 0.1 Bcf/d during the 
year ended December 31, 2023 as a result of our program to repurpose underutilized compressor units to expand existing or construct 
new compressor stations.  We plan to redeploy the compressor units taken offline during the year ended December 31, 2023 on the 
construction of new or expansion of existing compression stations.  As of December 31, 2023, we had the ability to store 5.5 million 
barrels of water in 36 impoundments.  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, 2023, substantially all of Antero Resources’ approximate 570,000 gross acres (515,000 net acres) are 
dedicated to us for gathering, compression and water services.  During the year ended December 31, 2023, Antero Resources 
produced, on average, 3.4 Bcfe/d net (34% liquids).  As of December 31, 2023, Antero Resources’ estimated net proved reserves were 
18.1 Tcfe, which were comprised of 59% natural gas, 40% NGLs and 1% oil.  As of December 31, 2023, Antero Resources’ drilling 
inventory consisted of 1,588 identified gross potential horizontal well locations (all of which were located 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 drilling program continues.   

Antero Resources announced its 2024 drilling and completion budget is $650 million to $700 million, and includes plans to 

complete 55 to 60 gross wells in the Appalachian Basin.  Additionally, Antero Resources’ 2024 capital budget includes $75 million to 
$100 million for leasehold expenditures, all of which will be dedicated to us.  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—Risks Related to Our Business.” 

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 assets (the “Marcellus gathering and compression agreement”) and (iii) a 
compression agreement acquired with the EnLink assets (the “Utica compression agreement” and, together with the 2019 gathering 
and compression agreement and the Marcellus gathering and compression agreement, the “gathering and compression agreements”).  
See “—Acquisitions” and Note 6—Property and Equipment 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.  Our 2019 gathering and compression agreement and Marcellus gathering 
and compression agreement have initial terms through 2038 and 2031, respectively, and our Utica compression agreement has two 
dedicated areas that expire in 2024 and 2030.  Upon expiration of the Marcellus gathering and compression agreement and Utica 
compression agreement, the Company 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. 

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.  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.  In addition, the Marcellus gathering and compression agreement provides for a 
minimum volume commitment that requires Antero Resources to utilize or pay for 25% of the compression capacity for a period of 10 
years from the in-service date.  Minimum volume commitments are aggregated such that there is a single minimum volume 
commitment for the respective service each year for each agreement.  Additional gathering lines and compressor stations installed on 
our own initiative are not subject to these minimum volume commitment 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. 

Our 2019 gathering and compression agreement included a growth incentive fee program that allowed for a reduction in our 

low pressure gathering fees if Antero Resources achieved certain volumetric targets.  Antero Resources’ throughput gathered under 
the Marcellus gathering and compression agreement was not considered in low pressure gathering volume targets.  Antero Resources 
earned $52 million in fee rebates during the year ended December 31, 2023 by achieving the first level volumetric target during the 
first, second and third quarters of 2023 and the second level volumetric target during the fourth quarter of 2023.  The growth incentive 

3 

 
fee rebate program expired on December 31, 2023. 

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 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.  
Under the agreement, we receive a fixed fee for all fresh water deliveries by pipeline directly to the well site, subject to annual CPI-
based adjustments.  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. 

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. 

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 its material leases, easements, 
rights-of-way, permits and licenses. 

4 

 
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 
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. 

5 

 
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 2024, FERC issued an order (Order No. 903) 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 $1,544,521 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”). 

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. 

6 

 
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 January 2024, those 
maximum civil penalties were increased to $266,015 and $2,660,135, 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.  Separately, in June 2021, PHMSA issued an Advisory Bulletin advising 
pipeline and pipeline facility operators of applicable requirements to update their inspection and maintenance plans for the elimination 
of hazardous leaks and minimization of natural gas released from pipeline facilities in accordance with the PIPES Act of 2020. 
PHMSA, together with state regulators, completed inspection of these plans in 2022.  Additionally, 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.  We do not expect our operations to be affected by these new rules any differently than other similarly situated midstream 
companies. 

Separately, in the Fiscal Year 2021 Omnibus Appropriations Bill, Congress directed PHMSA to move forward with several 

regulatory actions, the promulgation of rules related to changes in class location of existing pipelines, pipeline leak detection and 
repair and the management of idled pipelines, amongst other matters.  A Notice of Proposed Rulemaking was published in May 2023 
to address the management of methane emissions and other matters, and PHMSA is in the process of analyzing comments.  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. 

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; 

7 

 
• 

• 

• 

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 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 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.  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 

8 

 
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. 

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.  For example, in October 2015, the EPA lowered the National Ambient Air Quality Standard, 
for ozone from 75 to 70 parts per billion, and completed attainment/non-attainment designations in July 2018.  Subsequently, in 2020, 
the Trump Administration decided to leave this standard in place, but the Biden Administration has announced plans to formally 
review this decision and consider instituting a more stringent standard.  The EPA’s reconsideration of this standard remains ongoing.  
These decisions are subject to legal challenge, and any proposed rule will likely be subject to legal challenge as well.  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 
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. 

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 federal and state waters.  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 and damages.  
The scope of regulated waters has been subject to substantial controversy.  In 2015 and 2020, respectively, the Obama and Trump 

9 

 
Administrations each published final rules attempting to define the federal jurisdictional reach over waters of the United States 
(“WOTUS”).  However, both of these rulemakings were subject to legal challenge.  In January 2023, the EPA and Corps published a 
final rule based on the pre-2015 definition, with updates to incorporate existing Supreme Court decisions and regulatory guidance.  
However, the January 2023 rule was challenged and is currently enjoined in 27 states.  In May 2023, the U.S. Supreme Court released 
its opinion in Sackett v. EPA, which involved issues relating to the legal tests used to determine whether wetlands qualify as WOTUS.  
The Sackett decision invalidated certain parts of the January 2023 rule and significantly narrowed its scope, resulting in a revised rule 
being issued in September 2023.  However, due to the injunction on the January 2023 rule, the implementation of the September 2023 
rule currently varies by state.  In the 27 states, subject to the injunction, the agencies are interpreting the definition of WOTUS 
consistent with the pre-2015 regulatory regime and the changes made by the Sackett decision, which utilizes the “continuous surface 
connection” test to determine if wetlands qualify as WOTUS.  In the remaining 23 states, the agencies are implementing the 
September 2023 rule, which did not define the term “continuous surface connection.”  Therefore, some uncertainty remains as to how 
broadly the September 2023 rule and the Sackett decision will be interpreted by the agencies.  To the extent the implementation of the 
final rule, results of the litigation, or any action further expands 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, in 
April 2020, the federal district court for the District of Montana determined that the Corps CWA Section 404 Nationwide Permit 
(“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.  This vacatur was subsequently stayed by the U.S. Supreme Court in April 2022, and the EPA published a final rule to update 
and replace the relevant regulations in September 2023.  Litigation regarding the use of NWP 12 is ongoing.  Additionally, in March 
2022, the Corps announced it would seek stakeholder input on a formal review of NWP 12, which is also ongoing.  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. 

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.  We believe that compliance with such permits will not have a material 
adverse effect on our business operations. 

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.  We do not believe that any noncompliance 
with worker health and safety requirements has occurred or will have a material adverse effect on our business or operations. 

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 

10 

 
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. 

Climate Change 

In response to findings that emissions of GHGs present an endangerment to public health and the environment, the EPA 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.   

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

June 2016, the EPA finalized new regulations, known as Subpart OOOOa, that set emissions standards for methane and volatile 
organic compounds (“VOC”) from new and modified oil and natural gas production and natural gas processing and transmission 
facilities.  In September 2020, the EPA finalized amendments to the 2016 standards that removed the transmission and storage 
segment from the oil and natural gas source category and rescinded the methane-specific requirements for production and processing 
facilities.  However, President Biden signed an executive order on his first day in office calling for the suspension, revision or 
rescission of the September 2020 rule and the reinstatement or issuance of methane emission standards for new, modified and existing 
oil and gas facilities.  Subsequently, Congress approved, and President Biden has signed into law, a resolution under the 
Congressional Review Act to repeal the September 2020 revisions to the methane standards, effectively reinstating the prior standards.  
In response to President Biden's executive order calling on the EPA to revisit federal regulations regarding methane, 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, in December 2023.  Under the final rules, states have two years to prepare and 
submit their plans to impose methane emission controls on existing sources.  The presumptive standards established under the final 
rule are generally the same for both new and existing sources.  The requirements include enhanced leak detection survey requirements 
using optical gas imaging and other advanced monitoring to encourage the deployment of innovative technologies to detect and reduce 
methane emissions, reduction of emissions by 95% through capture and control systems and zero-emission requirements for certain 
devices.  This rule also establishes a “super emitter” response program that would allow third parties to make reports to EPA of large 
methane emission events, triggering certain investigation and repair requirements.  Fines and penalties for violations of these rules can 
be substantial.  It is likely, however, that the final rule and its requirements will be subject to legal challenges.  Moreover, compliance 
with the new rules may affect the amount we owe under the IRA 2022’s methane fee described below because compliance with EPA’s 
methane rules would exempt an otherwise covered facility from the requirement to pay the methane fee.  The requirements of the 
EPA’s final methane rules have the potential to increase our operating costs and thus may adversely affect our financial results and 
cash flows.  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 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.  These rules (and any additional regulations) could impose new compliance costs and permitting burdens 
on natural gas operations. 

In the United States, no comprehensive climate change legislation has been implemented at the federal level, though recently 

passed legislation such as the IRA 2022 advances numerous climate-related objectives.  President Biden has highlighted that 
addressing climate change is a priority of his administration.  On January 27, 2021, President Biden signed an executive order calling 
for substantial action on climate change, including among other things, the increased use of zero-emissions vehicles by the federal 
government, the elimination of subsidies provided to the oil and natural gas industry and increased emphasis on climate-related risks 
across agencies and economic sectors.  Additionally, in November 2021, the Biden Administration released “The Long-Term Strategy 
of the United States: Pathways to Net-Zero Greenhouse Gas Emissions by 2050,” which establishes a roadmap to net zero emissions 
in the United States by 2050 through, among other things, improving energy efficiency; decarbonizing energy sources via electricity, 
hydrogen and sustainable biofuels; and reducing non-CO2 GHG emissions, such as methane and nitrous oxide.  Other actions that 
could be pursued by the Biden Administration may include the imposition of more restrictive requirements for the establishment of 
pipeline infrastructure or the permitting of LNG export facilities, as well as more restrictive GHG emissions limitations for oil and gas 
facilities.  For example, on January 26, 2024, President Biden announced a temporary pause on pending decisions on new exports of 
LNG to countries that the United States does not have free trade agreements with, pending Department of Energy review of the 
underlying analyses for authorization.  The pause is intended to provide time to integrate certain considerations, including potential 
energy cost increases for consumers and manufacturers and the latest assessment of the impact of GHG emissions, and to ensure 

11 

 
 
adequate guards against health risks are in place.  In August 2022 the Inflation Reduction Act (“IRA 2022”) was signed into law, 
appropriating significant federal funding for renewable energy initiatives and, for the first time ever, imposing a federal fee on excess 
methane emissions from certain oil and gas facilities.  The emissions fee and renewable and low-carbon energy funding provisions of 
the law 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.  Internationally, the Paris Agreement requires member 
states to individually determine and submit non-binding emissions reduction targets every five years beginning in 2020.  President 
Biden recommitted the United States to the Paris Agreement in February 2021, and in April 2021, established a goal of reducing the 
United States’ emissions by 50-52% below 2005 levels by 2030. Additionally, in November 2021, the international community 
gathered again in Glasgow at the 26th Conference to the Parties on the UN Framework Convention on Climate Change (“COP26”), 
during which multiple announcements were made, including a call for parties to eliminate certain oil and natural gas subsidies and 
pursue further action on non-CO2 GHGs.  These goals were reaffirmed at the 27th Conference of the Parties in November 2022, and 
countries were called upon to accelerate efforts towards the phase-out of inefficient oil and natural gas subsidies, though no firm 
commitment or timeline was made.  At the 28th Conference of the Parties (“COP28”) in December 2023, the parties signed onto an 
agreement to transition away 
from fossil fuels in energy systems and increase renewable energy capacity, though no timeline for doing so was set.  While non-
binding, the agreements coming out of COP28 could result in increased pressure among financial institutions and various stakeholders 
to reduce or otherwise impose more stringent limitations on funding for and increase potential opposition to the exploration and 
production of fossil fuels.  Relatedly, the United States and European Union jointly announced the launch of the “Global Methane 
Pledge,” an initiative committing to a collective goal of reducing global methane emissions by at least 30% by 2030 relative to 2020 
levels, including “all feasible reductions” in the energy sector.  The impacts of these orders, pledges, agreements and any legislation or 
regulation promulgated to fulfill the United States’ commitments under the Paris Agreement, COP26, COP28 or other international 
conventions cannot be predicted at this time. 

Since 2017, we have published an annual ESG Report, which highlights our most significant environmental program 
improvements and initiatives.  As highlighted in our ESG Report, our methane leak loss rate in 2022 was 0.031%, 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%. 

During 2023, our GHG/methane emission reduction efforts included the following activities: 

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

•  Conducted three aerial flyovers of nine compressor station locations as part of our emissions monitoring initiatives. 

• 

• 

Installed pigging blowdown capture systems at eight locations including six compressor stations and two pipeline 
interchanges. 

Implemented a double-pig capture process that reduces the frequency of pig receiver blowdowns, which has the 
effect of reducing emissions and improving labor efficiency.   

•  Conducted a successful field pilot test with major engine manufacturer to reduce total carbon emissions while 

increasing the efficiency of the engine by adding additional horsepower, and developed a solution to deploy such 
technology on additional engines within our fleet.  

•  Utilized continuous monitoring technology over a tank farm at one of our compressor stations to identify and correct 

fugitive emissions that may occur between forward-looking infrared camera inspections. 

•  Developed, field tested and submitted patent pending technology that passed proof of concept examination for 
hydraulic emission displacement designed to eliminate GHG emissions from pipeline maintenance activities. 

•  Held meetings with our ESG Advisory Council that is comprised of a cross-disciplinary group of internal subject 
matter experts who partner with our GHG/Methane Reduction Team to manage ESG (including climate change) 
risks, opportunities and strategies. 

•  Held quarterly meetings with our GHG/Methane Reduction Team comprised of internal subject matter experts to 

review emerging methane detection and quantification technologies applicable to midstream operations. 

•  Developed a 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 

12 

 
 
to achieve our net zero scope 1 and scope 2 emissions targets by 2050. 

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 2023.  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 ESG matters, see “Item 
1A. Risk Factors—Business Operations—Increasing attention to ESG matters and conservation measures may adversely impact our 
business.” 

Increasingly, oil and natural gas companies are exposed to litigation risks from climate change.  A number of parties have 

brought suits against oil and natural gas companies in state or federal court for alleged contributions to, or failures to disclose the 
impacts of, climate change.  While we are not currently party to any such litigation, we could be named in future actions making 
similar claims of liability.  Moreover, to the extent that societal pressures or political or other factors are involved, it is possible that 
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 change policies.  Financial institutions may adopt policies that 

have the effect of reducing the funding provided to the oil and natural gas industry.  Many of the largest U.S. banks have made net 
zero commitments and have announced that they will be assessing financed emissions across their portfolios and taking steps to 
quantify and reduce those emissions.  For example, at COP26, the Glasgow Financial Alliance for Net Zero (“GFANZ”) announced 
that commitments from over 450 firms across 45 countries had resulted in over $130 trillion in capital committed to net zero goals.  
The various sub-alliances of GFANZ generally require participants to set short-term, sector-specific targets to transition their 
financing, investing and/or underwriting activities to net zero emissions by 2050.  These and other developments in the financial 
sector 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.  Additionally, financial 
institutions may be required to adopt policies that have the effect of reducing the funding provided to the oil and natural gas industry.  
For example, the Federal Reserve has joined the Network for Greening the Financial System (“NGFS”), a consortium of financial 
regulators focused on addressing climate-related risks in the financial sector and, in November 2021, issued a statement in support of 
the efforts of the NGFS to identify key issues and potential solutions for the climate-related challenges most relevant to central banks 
and supervisory authorities.  In January 2023, the Federal Reserve released instructions for a pilot climate scenario analysis being 
undertaken by six of the U.S.’s largest banks, which took place throughout 2023.  While we cannot predict what policies may result 
from this, 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 2022 the SEC proposed a rule requiring registrants to include certain climate-related disclosures, including 

Scope 1, 2 and 3 GHG emissions, climate-related targets and goals, and certain climate-related financial statement metrics, in 
registration statements and periodic reports.  The final rule is expected in the second quarter of 2024.  Similarly, in October 2023, the 
Governor of California signed the Climate Corporate Data Accountability Act (“CCDAA”) and Climate-Related Financial Risk Act 
(“CRFRA”) into law.  The CCDAA requires both public and private U.S. companies that are “doing business in California” and that 
have a total annual revenue of $1 billion to publicly disclose and verify, on an annual basis, Scope 1, 2 and 3 GHG emissions.  The 
CRFRA requires the disclosure of a climate-related financial risk report (in line with the Task Force on the Climate-Related Financial 
Disclosures (“TCFD”) recommendations or equivalent disclosure requirements under the International Sustainability Standards 
Board’s (“ISSB”) climate-related disclosure standards) every other year for public and private companies that are “doing business in 
California” and have total annual revenue of at least $500 million.  Reporting under both laws would begin in 2026.  Currently, the 
ultimate impact of these laws on our business is uncertain.  The Governor of California has directed further consideration of the 
implementation deadlines for each of the laws, and there is potential for legal challenges to be filed with respect to the scope of the 
law, but, absent clarification or revisions to the law, alongside the SEC proposed rule, finalization and implementation may result in 
additional costs to comply with these 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 with customers, regulators, 
investors or other stakeholders and could also increase our litigation risks relating to statements alleged to have been made by us or 
others in our industry regarding climate change 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.  
Although the final form and substance of these requirements is not yet known, and we cannot predict what any such rules may require 
to the extent the rules impose additional reporting obligations, we could face increased costs.  Additionally, we cannot predict how 

13 

 
 
 
financial institutions and investors might consider any information disclosed under a final rule when making investment decisions, and 
it is possible as a result that we could face increases with respect to the costs of, or restrictions imposed on, our access to capital.  
Separately, the SEC has also from time to time applied additional scrutiny to existing climate-change related disclosures in public 
filings, increasing the potential for enforcement if the SEC were to allege an issuer’s existing climate disclosures to be misleading or 
deficient. 

Moreover, climate change 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 
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, 2023, 604 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:  

• 

• 

• 

• 

•

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. 

Diversity, Inclusion and Workplace Culture  

We are committed to building a culture where diversity and inclusion are core philosophies across our operations.  We 
embrace an approach that values diversity, and we are also 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 diversity, inclusion and belonging.  Finally, in line with our commitments to equal 
employment opportunity and diversity and inclusion, 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.  
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; 

a reduction in or slowing of Antero Resources’ well completions, which would directly and adversely impact demand for 
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, 2023 

(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 
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 daily spot prices for NYMEX Henry Hub natural gas ranged from a high of $3.78 per MMBtu to a low of $1.74 per 

MMBtu in 2023, and the daily spot prices for NYMEX West Texas Intermediate crude oil ranged from a high of $93.67 per barrel to a 
low of $66.61 per barrel during the same period.  While oil and natural gas prices were substantially lower in 2023 than they were in 
2022, 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 (59% of equivalent proved reserves), changes in natural gas prices have 
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 

17 

 
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 
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. 

18 

 
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. 

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.  On March 8, 2018, the President of the United States issued two 
proclamations directing the imposition of ad valorem tariffs of 25% on certain imported steel products and 10% on certain imported 
aluminum products from most countries, with limited exceptions.  On May 31, 2018, the U.S. announced that it would also impose 
steel and aluminum tariffs on Canada, Mexico and the 28 member countries of the European Union.  Argentina, Australia, Brazil and 
South Korea implemented measures to address the impairment to U.S. national security attributable to steel and/or aluminum imports 
that were deemed satisfactory to the United States.  On May 19, 2019, the U.S. announced that Canada and Mexico had also 
implemented satisfactory measures to address the threatened impairment to U.S. national security caused by steel and aluminum 
imports from those countries.  As a result, imports of steel from Argentina, Australia, Brazil, Canada, Mexico and South Korea and 
aluminum from Argentina, Australia, Canada and Mexico have been exempted from the imposition of tariff-based remedies, but the 
United States has implemented quantitative restrictions in the form of absolute quotas for steel article imports from Argentina, Brazil 
and South Korea and aluminum products from Argentina, meaning that imports in excess of the allotted quota will be disallowed.  In 
addition, effective August 13, 2018, the United States announced that it would impose a 50% ad valorem tariff on steel articles 
imported from Turkey, which remained in effect until May 21, 2019, at which time a 25% ad valorem tariff on steel articles imported 
from Turkey was reimposed, consistent with the tariff on imports from most countries.  On January 24, 2020, the United States 
announced that an additional 25% ad valorem tariff would be imposed on certain derivative steel article imports from all countries 
except Argentina, Australia, Brazil, Canada, Mexico and South Korea, and that an additional 10% ad valorem tariff would be imposed 
on certain derivative aluminum article imports from all countries except Argentina, Australia, Canada and Mexico.  On August 6, 
2020, the U.S. re-imposed the 10% ad valorem tariff on imports of non-alloyed unwrought aluminum from Canada due to a surge in 
imports of those articles, but on October 27, 2020, retroactively reinstated Canada on the list of countries excluded from tariffs for 
those articles.  On August 28, 2020, the U.S. announced that it would lower one of the quantitative limitations on imports of certain 
steel articles from Brazil for the remainder of 2020.  The U.S. provided relief from these limitations in specific circumstances, namely 
for production activities with contracts for steel imports from Brazil during the fourth quarter of 2020 entered into before August 28, 
2020 that met other specified criteria.  In 2020, the U.S. and Mexico also engaged in discussions regarding steel imports pursuant to 
their Joint Statement of May 17, 2019.  On August 31, 2020, the Office of the U.S. Trade Representative announced that Mexico 
would establish a strict monitoring regime of exports of standard pipe, mechanical tubing and semi-finished steel products to the U.S. 
through June 1, 2021.  The U.S. agreed to continue to exempt Mexico from duty on these imports.  On November 5, 2020, the Office 
of the U.S. Trade Representative announced that Mexico agreed to establish a strict monitoring regime for exports of certain grain-
oriented electrical steel (“GOES”)-containing products into the U.S., and the U.S. agreed that Mexico would not be subject to any 
adjustments of imports of electrical transformers or related parts.  In addition, the U.S.-Mexico-Canada Free Trade Agreement 
(“USMCA”) became effective on July 1, 2020.  The USMCA includes agreements related to steel and aluminum imports, including 
changes to rules-of-origin requirements for steel and aluminum materials originating in North America, rules for determining whether 
goods containing materials from non-USMCA countries are considered “North American” under the Harmonized Tariff Schedule, and 

19 

 
tariff exemptions for certain automotive imports.  Following these proclamations, domestic prices for steel have risen and are expected 
to continue to rise.   These price increases 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 change-related effects 
such as 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. 

Increasing attention to ESG matters and conservation measures may adversely impact our business. 

Increasing attention to climate change, societal expectations on companies to address climate change, investor, regulatory, 

and societal expectations regarding voluntary and mandatory ESG 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.  Increasing attention to climate change and environmental conservation, for 

20 

 
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.  To the extent that societal pressures or regulatory or political or other 
factors are involved, it is possible that such liability could be imposed without regard to our causation of or contribution to the asserted 
damage, or to other mitigating factors.  And 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 ESG matters from time to time, many of the 

statements in those voluntary disclosures are based on hypothetical expectations and assumptions 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 ESG-related disclosure is also emerging 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 are necessarily uncertain and may be prone to error or 
subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring 
and reporting on many ESG matters.  Additionally, while we may also announce various voluntary ESG targets, including our goals to 
achieve a 100% reduction in pipeline emissions by 2025 and to achieve net zero Scope 1 (direct) and Scope 2 (indirect from the 
purchase of energy) emissions by 2050, 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 ESG impact instead of actual changes in our 
ESG 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.  In 
addition, while we may seek to only 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.  
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, are 
instituting 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 ESG profile of our operations, we cannot 
guarantee that such participation or certification will have the intended results on our ESG profile.  Also, despite these aspirational 
goals, we may receive pressure from investors, lenders or other groups to adopt more aggressive climate or other ESG-related goals, 
but we cannot guarantee that we will be able to implement such goals 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 ESG plans or goals or stakeholder perceptions of statements made by us, 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 
ESG matters are becoming increasingly subject to heightened scrutiny from public and governmental authorities related to the risk of 
potential “greenwashing,” i.e., misleading information or false claims overstating potential ESG benefits.  As a result, we may face 
increased litigation risks from private parties and governmental authorities related to our ESG 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 processes for evaluating companies on their approach to ESG matters.  Such ratings may be used by some investors to inform 
their investment and voting decisions.  Unfavorable ESG 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, institutional lenders may decide not to provide funding for oil and natural gas companies or the 
corresponding infrastructure projects based on climate change related concerns, which could affect our access to capital for potential 
growth projects.  Moreover, to the extent ESG 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 ESG matters may also impact Antero Resources and 
our customers, which may adversely impact our business, financial condition or results of operations. 

21 

 
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; 

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. 

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. 

22 

 
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 
customers, suppliers, investors and other stakeholders.  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.  
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.  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.  A 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, 

23 

 
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 our revolving 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 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 capital markets, including 
the market for senior unsecured notes, and our financial condition at such time.  Any refinancing of our indebtedness, including using 
borrowings under our revolving 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 indentures governing our senior notes, may restrict 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.  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.  Our revolving 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. 

24 

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

Our revolving credit facility limits our ability to, among other things: 

• 

• 

incur or guarantee additional debt; 

redeem or repurchase stock or make distributions under certain circumstances; 

•  make certain investments; 

• 

• 

• 

enter into mergers; 

incur certain liens or permit them to exist; 

enter into certain types of transactions with affiliates; 

•  merge or consolidate with another company; and 

• 

transfer, sell or otherwise dispose of assets. 

The indentures governing our senior notes contains similar restrictive covenants.  In addition, our revolving 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 our revolving credit facility if doing so would cause us to breach a financial covenant. 

The provisions of our revolving 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 
conditions.  In addition, a failure to comply with the provisions of our revolving credit facility or the indentures governing our senior 
notes could result in a default or an event of default that 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 “Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital 
Resources and Liquidity.” 

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. 

25 

 
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 
2023, we had average outstanding borrowings under our revolving credit facility of $774 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 $8 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 Takeovers 

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 
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. 

26 

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

transactions.  Our revolving 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;  

provide that (i)  Yorktown Partners LLC (“Yorktown”) and their affiliates are permitted to participate (directly or 
indirectly) in venture capital and other direct investments in corporations, joint ventures, limited liability companies and 
other entities conducting business of any kind, nature or description, (ii) Yorktown and their affiliates are permitted to 
have interests in, participate with, aid and maintain seats on the boards of directors or similar governing bodies of any 
such investments, in each case that may, are or will be competitive with our business and the business of our subsidiaries 
or in the same or similar lines of business as us and our subsidiaries, or that could be suitable for us or our subsidiaries 
and (iii) we have, subject to limited exceptions, renounced, to the fullest extent permitted by law, any interest or 
expectancy in, or in being offered an opportunity to participate in, such corporate opportunities;  

• 

provide that the provisions of our certificate of incorporation can only be amended or repealed by the affirmative vote of 
the holders of at least 66 2/3% in voting power of the outstanding shares of our common stock entitled to vote thereon, 
voting together as a single class; provided, however, that so long as the Stockholders' Agreement remains in effect, no 

27 

 
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 
together as a single class.  However, so long as the Stockholders’ Agreement remains in effect, our Board may not 
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 
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. 

28 

 
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. 

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 

29 

 
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 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 example, 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.  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 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.  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.  In 2015 and 2020, respectively, the Obama 

and Trump Administrations each published final rules attempting to define the federal jurisdictional reach over WOTUS.  However, 
both of these rulemakings were subject to legal challenge.  In January 2023, the EPA and Corps published a rule to finalize a rule 
based on the pre-2015 regulations, incorporating updates from Supreme Court decisions and regulatory guidance.  However, the 
January 2023 rule was challenged and is currently enjoined in 27 states.  In May 2023, the U.S. Supreme Court released its opinion in 
Sackett v. EPA, which involved issues relating to the legal tests used to determine whether wetlands qualify as WOTUS under the 
rule.  The Sackett decision invalidated certain parts of the January 2023 rule and significantly narrowed its scope, resulting in a 
revised rule being issued in September 2023.  However, due to the injunction on the January 2023 rule, the implementation of the 
September 2023 rule currently varies by state.  In the 27 states, subject to the injunction, the agencies are interpreting the definition of 
WOTUS consistent with the pre-2015 regulatory regime and the changes made by the Sackett decision, which utilizes the “continuous 
surface connection” test to determine if wetlands qualify as WOTUS.  In the remaining 23 states, the agencies are implementing the 
September 2023 rule, which did not define the term “continuous surface connection.”  Therefore, some uncertainty remains as to how 
broadly the September 2023 rule and the Sackett decision will be interpreted by the agencies.  To the extent any action further expands 
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.  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. 

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 

30 

 
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 $1,544,521 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.  For example, the EPA 
finalized rules in June 2016 that prohibit the discharge of wastewater from hydraulic fracturing operations to publicly owned 
wastewater treatment plants. 

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 

31 

 
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.  For example, President Biden has made action on environmental matters, and climate change in 
particular, a focus of his administration, and our operations and those of our clients, may be subject to greater environmental, health 
and safety restrictions, particularly with regards to hydraulic fracturing, permitting and GHG emissions. 

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 accelerate the transition to a low carbon economy 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.  In addition, the IRA 2022 imposes the first ever federal fee on the 
emission of greenhouse gases through a methane emissions charge.  The IRA 2022 amends the federal Clean Air Act to impose a fee 
on the emission of 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 methane emissions charge would start in 
calendar year 2024 at $900 per ton of methane, increase to $1,200 in 2025, and be set at $1,500 for 2026 and each year after.  
Calculation of the fee is based on certain thresholds established in the IRA 2022.  The methane charge and the incentives for 
renewable energy infrastructure development could impose additional costs on our operations and further accelerate the transition of 
the economy away from the use of oil and natural gas towards lower- or zero-carbon emissions alternatives.  This could decrease 
demand for oil and gas and consequently, adversely affect our business and results of operations and those of our customers. 

Our operations are subject to a series of risks related to climate change 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.  

The threat of climate change continues to attract considerable attention in the United States and in foreign countries.  In the 

United States, no comprehensive climate change legislation has been implemented at the federal level.  However, President Biden has 
highlighted addressing climate change as a priority of his administration, which includes certain potential initiatives for climate 
change legislation to be proposed and passed into law.  Moreover, 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.  For example, 
in response to findings that emissions of carbon dioxide, methane and other GHGs endanger public health and the environment, 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.  

32 

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

June 2016, the EPA finalized NSPS, known as Subpart OOOOa, that established emission standards for methane and VOCs from new 
and modified oil and natural gas production and natural gas processing and transmission facilities.  In September 2020, the EPA 
finalized amendments to the 2016 standards that removed the transmission and storage segment from the oil and natural gas source 
category and rescinded the methane-specific requirements for production and processing facilities.  However, President Biden signed 
an executive order on his first day in office calling for the suspension, revision or rescission of the September 2020 rule and the 
reinstatement or issuance of methane emission standards for new, modified and existing oil and gas facilities.  Subsequently, the U.S. 
Congress approved, and President Biden has signed into law, a resolution under the Congressional Review Act to repeal the 
September 2020 revisions to the methane standards, effectively reinstating the prior standards.  In response to President Biden's 
executive order calling on the EPA to revisit federal regulations regarding methane, 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, in December 2023.  Under the final rules, states have two years to prepare and submit their plans to impose 
methane emission controls on existing sources.  The presumptive standards established under the final rule are generally the same for 
both new and existing sources.  The requirements include enhanced leak detection survey requirements using optical gas imaging and 
other advanced monitoring to encourage the deployment of innovative technologies to detect and reduce methane emissions, reduction 
of emissions by 95% through capture and control systems and zero-emission requirements for certain devices.  The rule also 
establishes a “super emitter” response program that would allow third parties to make reports to EPA of large methane emission 
events, triggering certain investigation and repair requirements.  Fines and penalties for violations of these rules can be substantial.  It 
is likely, however, that the final rule and its requirements will be subject to legal challenges.  Moreover, compliance with the new 
rules may affect the amount we owe under the IRA’s methane fee described above because compliance with EPA’s methane rules 
would exempt an otherwise covered facility from the requirement to pay the methane fee.  The requirements of the EPA’s final 
methane rules have the potential to increase our operating costs and thus may adversely affect our financial results and cash flows.  
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 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. 

Internationally, the Paris Agreement requires member states to individually determine and submit non-binding emissions 

reduction targets every five years beginning 2020.  President Biden recommitted the United States to the Paris Agreement in February 
2021 and, in April 2021, announced a goal of reducing the United States’ emissions by 50-52% below 2005 levels by 2030.  
Additionally, in November 2021, the international community gathered again in Glasgow COP26, during which multiple 
announcements were made, including a call for parties to eliminate certain oil and natural gas subsidies and pursue further action on 
non-CO2 GHGs.  At COP28 in December 2023, the parties signed onto an agreement to transition away from fossil fuels in energy 
systems and increase renewable energy capacity, though no timeline for doing so was set.  While non-binding, the agreements coming 
out of COP28 could result in increased pressure among financial institutions and various stakeholders to reduce or otherwise impose 
more stringent limitations on funding for and increase potential opposition to the exploration and production of fossil fuels.  Relatedly, 
the United States and European Union jointly announced the launch of the “Global Methane Pledge,” an initiative committing to a 
collective goal of reducing global methane pollution by at least 30% by 2030 relative to 2020 levels, including “all feasible 
reductions” in the energy sector.  The impacts of these orders, pledges, agreements and any legislation or regulation promulgated to 
fulfill the United States’ commitments under the Paris Agreement, COP26, COP28 or other international conventions cannot be 
predicted at this time. 

Concern over the threat of climate change has also resulted in increasing political risks in the United States, including 

climate-change related pledges made by President Biden and other public office representatives.  On January 27, 2021, President 
Biden signed an executive order calling for substantial action on climate change, including among other things, the increased use of 
zero-emissions vehicles by the federal government, the elimination of subsidies provided to the oil and natural gas industry and 
increased emphasis on climate-related risks across agencies and economic sectors.  Additionally, in November 2021, the Biden 
Administration released “The Long-Term Strategy of the United States: Pathways to Net-Zero Greenhouse Gas Emissions by 2050,” 
which establishes a roadmap to net zero emissions in the United States by 2050 through, among other things, improving energy 
efficiency; decarbonizing energy sources via electricity, hydrogen and sustainable biofuels; and reducing non-CO2 GHG emissions, 
such as methane and nitrous oxide.  Other actions that could be pursued by the Biden administration include more restrictive 
requirements for the development of pipeline infrastructure or LNG export facilities, as well as more restrictive GHG emissions 
limitations for oil and gas facilities.  For example, on January 26, 2024, President Biden announced a temporary pause on pending 
decisions on new exports of LNG to countries that the United States does not have free trade agreements with, pending Department of 
Energy review of the underlying analyses for authorization.  The pause is intended to provide time to integrate certain considerations, 
including potential energy cost increases for consumers and manufacturers and the latest assessment of the impact of GHG emissions, 
and to ensure adequate guards against health risks are in place. 

33 

 
Increasingly, oil and natural gas companies are also exposed to litigation risks from climate change.  A number of parties 

have brought suits against oil and natural gas companies in state or federal court for alleged contributions to, or failures to disclose the 
impacts of, climate change.  While we are not currently party to any such litigation, we could be named in future actions making 
similar claims of liability.  Moreover, to the extent that societal pressures or political or other factors are involved, it is possible that 
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, in response to concerns related to climate change, 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.  
Institutional lenders who provide financing to oil and natural gas companies have also become more attentive to sustainable lending 
practices, and some of them may elect in future not to provide funding for oil and natural gas companies.  Many of the largest U.S. 
banks have made net zero commitments and have announced that they will be assessing financed emissions across their portfolios and 
taking steps to quantify and reduce those emissions.  In addition, at COP26, GFANZ announced that commitments from over 450 
firms across 45 countries had resulted in over $130 trillion in capital committed to net zero goals.  The various sub-alliances of 
GFANZ generally require participants to set short-term, sector-specific targets to transition their financing, investing and/or 
underwriting activities to net zero emissions by 2050.  These and other developments in the financial sector 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.  The Federal Reserve has joined 
the NGFS, a consortium of financial regulators focused on addressing climate-related risks in the financial sector and, in November 
2021, issued a statement in support of the efforts of the NGFS to identify key issues and potential solutions for the climate-related 
challenges most relevant to central banks and supervisory authorities.  The Federal Reserve also recently released instructions for a 
pilot climate scenario analysis being undertaken by six of the U.S.’s largest banks through 2023.  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 2022 the SEC proposed a rule requiring registrants to include certain climate-related disclosures, including 

Scope 1, 2 and 3 GHG emissions, climate-related targets and goals, and certain climate-related financial statement metrics, in 
registration statements and periodic reports.  The final rule is expected in the second quarter of 2024.  Similarly, in October 2023, the 
Governor of California signed the CCDAA and CRFRA into law.  The CCDAA requires both public and private U.S. companies that 
are “doing business in California” and that have a total annual revenue of $1 billion to publicly disclose and verify, on an annual basis, 
Scope 1, 2 and 3 GHG emissions.  The CRFRA requires the disclosure of a climate-related financial risk report (in line with the TCFD 
recommendations or equivalent disclosure requirements under the ISSB climate-related disclosure standards) every other year for 
public and private companies that are “doing business in California” and have total annual revenue of at least $500 million.  Reporting 
under both laws would begin in 2026.  Currently, the ultimate impact of these laws on our business is uncertain—the Governor of 
California has directed further consideration of the implementation deadlines for each of the laws, and there is potential for legal 
challenges to be filed with respect to the scope of the law—but, absent clarification or revisions to the law, alongside the SEC 
proposed rule, finalization and implementation may result in additional costs to comply with these 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 with customers, regulators, investors or other stakeholders and could also increase our litigation risks 
relating to statements alleged to have been made by us or others in our industry regarding climate change 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.  Although the final form and substance of these requirements is not yet known, 
and we cannot predict what any such rules may require to the extent the rules impose additional reporting obligations, we could face 
increased costs or limitations or restrictions on our access to capital.  Separately, the SEC has also from time to time applied additional 
scrutiny to existing climate-change related disclosures in public filings, increasing the potential for enforcement if the SEC were to 
allege an issuer’s existing climate disclosures misleading or deficient. 

The adoption and implementation of new or more stringent international, federal or state legislation, regulations or other 

regulatory initiatives related to climate change 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.   

Moreover, climate change 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 

34 

 
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.  In addition, while our consideration of changing weather conditions and 
inclusion of safety factors in design covers the uncertainties that climate change and other events may potentially introduce, our ability 
to mitigate the adverse impacts of these events depends in part on the effectiveness of our facilities and our disaster preparedness and 
response and business continuity planning, which may not have considered or be prepared for every eventuality. 

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 January 2024, those 
maximum civil penalties were increased to $266,015 and $2,660,135, 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.  Separately, in June 2021, PHMSA issued an Advisory Bulletin advising 
pipeline and pipeline facility operators of applicable requirements to update their inspection and maintenance plans for the elimination 
of hazardous leaks and minimization of natural gas released from pipeline facilities, in accordance with the PIPES Act of 2020.  
PHMSA, together with state regulators, are expected to commence and complete inspection of these plans in 2022.  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.  We do not expect our operations to be affected by these new rules any differently than other similarly situated 
midstream companies.  Separately, in the Fiscal Year 2021 Omnibus Appropriations Bill, Congress directed PHMSA to move forward 
with several regulatory actions, the promulgation of rules related to changes in class location of existing pipelines, pipeline leak 
detection and repair and the management of idled pipelines, amongst other matters.  A Notice of Proposed Rulemaking was published 
in May 2023 to address management of methane emissions and other matters and PHMSA is in the process of analyzing comments.  
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 
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 Paul M. Rady, Chairman, President and Chief Executive Officer, 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, 

2023, Antero Resources beneficially owned 29.0% 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. 

36 

 
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. 

Certain of our stockholders have investments in our affiliates that may conflict with the interests of other stockholders. 

Paul M. Rady and an individual affiliated with Yorktown serve as members of our Board and the Board of Directors of 

Antero Resources.  Mr. Rady and Yorktown also own a significant portion of the shares of common stock of Antero Resources.  As a 
result of their investments in Antero Resources, Mr. Rady and Yorktown may have conflicting interests with other stockholders.  
Conflicts of interest could arise in the future between us, on the one hand, and Mr. Rady and Yorktown, on the other hand, regarding, 
among other things, decisions related to our financing, capital expenditures and growth plans, the terms of our agreements with Antero 
Resources and its subsidiaries and the pursuit of potentially competitive business activities or business opportunities. 

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 2027.  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 the majority of our distributions to be in excess of our earnings and profits 
through 2027.  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.   

37 

 
 
 
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. 

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. 

38 

 
 
 
 
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;  

changes in revenue or earnings estimates or publication of research reports by analysts;  

speculation by the press or investment community;  

sales of our common stock by other stockholders;  

announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures, 
securities offerings or capital commitments;  

general market conditions;  

changes in accounting standards, policies, guidance, interpretations or principles;  

adverse changes in tax laws or regulations;  

domestic and international economic, legal and regulatory factors related to our performance; and 

•  Antero Resources’ operating and financial performance and prospects, and the trading price of its common stock. 

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 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. 

39 

 
         
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 
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.

Not applicable. 

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: 

40 

 
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 Chief Administrative Officer (“CAO”) 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. 

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 CAO 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. 

41 

 
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 CAO, 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 CAO 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 CAO 
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 CAO, Aaron S.G. Merrick, has more than 25 years of experience in the technology sector and 16 years of experience in 

managing cybersecurity risk.  Mr. Merrick was named CAO in 2022 and previously served as our Vice President – IT since 2016.  
Prior to joining Antero, he held IT leadership positions of increasing responsibility at Apache Corporation, including Director of IT 
from 2006 to 2009 and Vice President of IT from 2009 to 2015.  Additionally, Mr. Merrick was President of a computer consulting 
business from 2002 to 2006, and he also held several positions of increasing responsibility at T-NETIX, Inc., including Vice President 
of IT, during his tenure from 1995 to 2000.  Mr. Merrick graduated from Bob Jones University in 1984 with a Bachelor of Science 
degree in Accounting. 

Impact of Risks from Cybersecurity Threats 

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. 

See Note 15—Contingencies to the consolidated financial statements for additional information.

Stock Performance Graph 

The graph below shows the cumulative total shareholder return assuming the investment of $100 on December 31, 2018, in 

each of (i) our predecessor’s, Antero Midstream GP LP, common shares through March 12, 2019 and our common stock thereafter 
(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 
Antero Resources’ wells in 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. 

Financing Highlights 

Issuance of Senior Notes 

On January 16, 2024, we issued $600 million of 6.625% senior notes due February 1, 2032 (the “2032 Notes”) at par.  The 
2032 Notes are unsecured and effectively subordinated to the Credit Facility to the extent of the value of the collateral securing the 
Credit Facility.  The 2032 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 repay outstanding borrowings on the Credit Facility.  See Note 8—Long-Term Debt to the 
consolidated financial statements for more information. 

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.  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 

Prices for natural gas, NGLs and oil decreased significantly during the year ended December 31, 2023 as compared to the 

year ended December 31, 2022.  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’ improved liquidity and leverage position as 
compared to historical levels, we do not expect to experience significant variability in our throughput volumes resulting from volatile 
commodity prices. 

45 

 
 
Growth Incentive Fee Program with Antero Resources 

Our 2019 gathering and compression agreement with Antero Resources included a growth incentive fee program whereby we 
agreed to provide quarterly fee rebates to Antero Resources through December 31, 2023, contingent upon Antero Resources achieving 
volumetric growth targets on low pressure gathering.  Antero Resources’ throughput gathered under the gathering and compression 
agreements acquired with the Crestwood assets was not considered in the low pressure gathering volume targets.  During the year 
ended December 31, 2022, Antero Resources earned $48 million in fee rebates by achieving the first level volumetric target during 
each quarter in 2022.  During the year ended December 31, 2023, Antero Resources earned $52 million in fee rebates by achieving the 
first level volumetric target during the first, second and third quarters of 2023 and the second level volumetric target during the fourth 
quarter of 2023.  The growth incentive fee rebate program expired on December 31, 2023. 

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 2023.  For example, CPI for all urban consumers increased 8% from the 
year ended December 31, 2021 to the year ended December 31, 2022 and an additional 4% from the year ended December 31, 2022 to 
the year ended December 31, 2023 as compared to the Federal Reserve’s stated goal of 2%.  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 
March 2022 in an effort to bring the inflation rate in line with its stated goal of 2% on a long-term basis.  Between March 2022 and 
December 2023, the Federal Reserve increased the federal funds interest rate by 5.25%.  While inflationary pressures in the United 
States’ economy have begun to subside, we continue to be impacted by the increased federal funds interest rate.  See “—Results of 
Operations” for additional information. 

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 on Russia and other global trade restrictions, among others.  However, 
neither our nor Antero Resources’ supply chain has experienced any significant interruptions due to such events. 

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 2032.  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 5—Revenue to the consolidated financial statements for more 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 

46 

 
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 570,000 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, 2023, Antero Resources had disclosed 
estimated net proved reserves of 18.1 Tcfe, of which 59% was natural gas, 40% were NGLs and 1% was oil.  As of 
December 31, 2023, Antero Resources’ drilling inventory consisted of 1,588 gross identified potential horizontal well 
locations, all of which were on acreage dedicated to us, providing us with significant opportunity for future capital 
investments as Antero Resources’ drilling program continues.  See Note 5—Revenue to the consolidated financial 
statements for more 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 to a lesser extent the 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 (i) costs allocated to Antero Midstream by Antero Resources for grants made prior to March 12, 2019 pursuant 
to the Antero Resources Corporation Long-Term Incentive Plan and (ii) costs related to the Antero Midstream 
Corporation Long-Term Incentive Plan. 

•  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 6—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 revolving credit 
facility and with senior unsecured notes.  Our interest expense also includes amortization of deferred financing costs 
incurred in connection with our revolving credit facility and senior notes and amortization of senior notes premiums.  
See Note 8—Long-Term Debt to our consolidated financial statements and “—Capital Resources and Liquidity—Debt 
Agreements” for additional information on our debt agreements. 

47 

 
 
• 

Income tax expense.  We are subject to state and federal income taxes but are currently not in a cash tax paying position 
with respect to state and 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, 2023, we had U.S. federal NOL carryforwards of $428 
million and state NOL carryforwards of $496 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 7—Income Taxes to our consolidated financial statements for a discussion of 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.

Revenues.  Total revenues increased by $122 million, from $920 million for the year ended December 31, 2022, to $1,042 

million for the year ended December 31, 2023.  Total revenues included amortization of customer relationships of $71 million during 
each of the years ended December 31, 2022 and 2023.  Gathering and processing revenues increased by 14%, from $706 million for 
the year ended December 31, 2022 to $805 million for the year ended December 31, 2023.  Water handling revenues increased by 
11%, from $214 million for the year ended December 31, 2022 to $237 million for the year ended December 31, 2023.  These 
fluctuations primarily resulted from the following: 

Gathering and Processing 

•  Low pressure gathering revenue increased $47 million period over period primarily due to increased throughput volumes of 
114 Bcf, or 314 MMcf/d, and higher low pressure gathering rates as a result of annual CPI-based adjustments, partially 
offset by higher fee rebates of $4 million between periods.  Low pressure gathering volumes increased between periods 
primarily due to 86 additional wells being connected to our system since December 31, 2022 and 253 wells that were 
connected to the assets we acquired during the fourth quarter of 2022. 

•  Compression revenue increased $37 million period over period due to increased throughput volumes of 153 Bcf, or 418 
MMcf/d, and higher compression rates as a result of the annual CPI-based adjustments.  Compression volumes increased 
between periods primarily due to the 86 additional wells connected to our system since December 31, 2022 and 12 
compressor stations and 253 wells that were connected to the assets we acquired during the fourth quarter of 2022. 

•  High pressure gathering revenue increased $15 million period over period primarily due to increased throughput volumes 

of 41 Bcf, or 112 MMcf/d, and an increased high pressure gathering rate as a result of an annual CPI-based adjustment.  The 
high pressure gathering volumes increased period over period primarily due to 86 additional wells being connected to our 
high pressure system since December 31, 2022.  The assets acquired during 2022 were already connected to high pressure 
systems operated by us or third parties prior to such acquisitions, and therefore, the 253 wells connected to the acquired 
assets did not increase the throughput on our high pressure gathering system.

Water Handling 

•  Fresh water delivery revenue increased $11 million period over period primarily due to a 3% increase to the fresh water 
delivery rate for our long-term contract with Antero Resources as a result of the annual CPI-based adjustment and higher 
fresh water delivery volumes of 1 MMBbl, or 4 MBbl/d.  Fresh water delivery volumes increased between periods due to 
higher well completions by Antero Resources. 

•  Other fluid handling services revenue increased $12 million period over period primarily due to increased costs, partially 

due to inflationary pressures that impact our cost plus 3% and cost of service rates during the year ended December 31, 
2023, and higher other fluid handling volumes of 1 MMBbl, or 3 MBbl/d, between periods. 

Direct operating expenses.  Direct operating expenses increased by 18%, from $180 million for the year ended December 31, 
2022 to $213 million for the year ended December 31, 2023.  Gathering and processing direct operating expenses increased 26% from 
$76 million for the year ended December 31, 2022 to $96 million for the year ended December 31, 2023 primarily due to 12 
compressor stations that were acquired during the fourth quarter of 2022 and increased heavy maintenance expense between periods.  
Water handling direct operating expenses increased by 13%, from $104 million for the year ended December 31, 2022 to $117 million 
for the year ended December 31, 2023 primarily due to higher wastewater trucking expenses, an increased number of locations 
connected to our water blending system and higher fresh water volumes between periods. 

General and administrative (excluding equity-based compensation) expenses.  General and administrative expenses 
(excluding equity-based compensation expense) decreased 7%, from $42 million for the year ended December 31, 2022 to $39 million 
for the year ended December 31, 2023 primarily due to lower legal costs associated with the Veolia legal matter between periods and 
lower costs allocated to us from Antero Resources.  See Note 15—Contingencies to our consolidated financial statements for 
additional information.   

Equity-based compensation expenses.  Equity-based compensation expenses increased by 61% from $20 million for the year 

ended December 31, 2022 to $32 million for the year ended December 31, 2023 primarily due to an increase in the annual equity 
awards granted during the years ended December 31, 2022 and 2023 as compared to prior years, which were temporarily and 
significantly reduced during 2020 and supplemented by our cash awards program.  Our equity awards vest over three or four year 
service periods, and our equity incentive program began returning to normal levels in 2021.  See Note 10—Equity-Based 
Compensation to our consolidated financial statements for additional information.   

Depreciation expense.  Depreciation expense increased by 3% from $132 million for the year ended December 31, 2022 to 
$136 million for the year ended December 31, 2023.  This increase was primarily due to $4 million for our assets acquired during the 
fourth quarter of 2022 and $3 million related to assets placed in service between periods, partially offset by $3 million of lower 
expense related to our program to repurpose underutilized compressor units to expand existing or construct new compressor stations 
between periods. 

Impairment of property and equipment expense.  Impairment of property and equipment expense of $4 million for the year 

ended December 31, 2022 was primarily due to (i) a write-down of the Clearwater Facility related to the retirement obligation for the 
facility and (ii) cancelled projects.  Impairment of property and equipment expense during the year ended December 31, 2023 related 
to cancelled projects. 

Loss (gain) on asset sale.  Gain on asset sale of $2 million for the year ended December 31, 2022 was primarily due to (i) the 

sale of four compressor engines, (ii) reimbursement of certain cancelled project costs and (iii) sales of miscellaneous equipment and 
excess pipe inventory.  Loss on asset sale of $6 million for the year ended December 31, 2023 was primarily due to sales of 
miscellaneous equipment. 

Interest expense.  Interest expense increased by 14%, from $190 million for the year ended December 31, 2022 to $217 

million for the year ended December 31, 2023 primarily due to increased interest rates on our Credit Facility due to higher benchmark 
rates during the year ended December 31, 2023 and higher average borrowings on our Credit Facility between periods as a result of 
our asset acquisitions during the fourth quarter of 2022. 

Equity in earnings of unconsolidated affiliates.  Equity in earnings in unconsolidated affiliates increased by 12%, from 

$94 million for the year ended December 31, 2022 to $105 million for the year ended December 31, 2023 primarily due to increased 
processing and fractionation volumes and higher processing and fractionation fees as a result of annual CPI-based adjustments. 

51 

 
Income tax expense.  Income tax expense increased by 9% from $117 million for the year ended December 31, 2022 to $128 

million for the year ended December 31, 2023, which reflects effective tax rates of 26.5% and 25.7%, respectively.  This income tax 
expense increase was primarily due to higher pre-tax income between periods. 

Year Ended December 31, 2021 Compared to Year Ended December 31, 2022 

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

Operations” in our 2022 Annual Report on Form 10-K for a discussion of the results of operations for the year ended December 31, 
2021 compared to the year ended December 31, 2022.   

Capital Resources and Liquidity 

Sources and Uses of Cash 

Capital resources and liquidity are provided by operating cash flows, available borrowings under our Credit Facility and 

capital market transactions.  See Note 8—Long-Term Debt to our consolidated financial statements.  We expect that the combination 
of these capital resources will be adequate to meet our working capital requirements, capital expenditures program and expected 
quarterly cash dividends for at least the next 12 months. 

During the year ended December 31, 2023, we paid dividends of $0.90 per share, or a total of $435 million, to holders of our 

common stock, as applicable, and we paid $550,000 of dividends on our Series A Preferred Stock.  On January 10, 2024, the Board 
declared a cash dividend on the shares of our common stock of $0.2250 per share for the quarter ended December 31, 2023.  The 
dividend was paid on February 7, 2024 to stockholders of record as of January 24, 2024.  Our Board also declared a cash dividend of 
$137,500 on our Series A Preferred Stock that was paid on February 14, 2024 in accordance with their terms.  As of December 31, 
2023, there were dividends in the amount of $68,750 accumulated in arrears on our Series A Preferred Stock.  See Note 11—Cash 
Dividends and Note 12—Equity and Net Income Per Common Share to our consolidated financial statements for additional 
information. 

As of December 31, 2023, we did not have any off-balance sheet arrangements.

Year Ended December 31, 2022 Compared to Year Ended December 31, 2023 

Operating Activities.  Net cash provided by operating activities was $700 million and $779 million for the years ended 

December 31, 2022 and 2023, respectively.  The increase in cash flows provided by operations between periods was primarily due to 
(i) higher revenues in the gathering and processing and water handling segments, (ii) higher distributions from unconsolidated 
affiliates and (iii) a $10 million tax refund received during the year ended December 31, 2023, partially offset by higher direct 
operating and interest expenses and changes in working capital between periods. 

Investing Activities.  Net cash flows used in investing activities decreased by $311 million from $494 million for the year 

ended December 31, 2022 to $183 million for the year ended December 31, 2023 primarily due to decreased asset acquisitions of $217 
million and capital spending for our gathering systems and facilities, water handling systems and other assets of $115 million, partially 
offset by decreased return of investment  in the Joint Venture of $17 million and asset sale proceeds of $5 million during the year 
ended December 31, 2022.  The capital spending for our gathering systems, facilities and other and water handling systems decreased 
between periods primarily as a result of fewer capital projects during the year ended December 31, 2023.

Financing Activities.  Net cash used in financing activities was $206 million and $596 million for the years ended 

December 31, 2022 and 2023, respectively.  The increase in cash flows used in financing activities between periods was primarily due 
to net repayments on our Credit Facility of $152 million during the year ended December 31, 2023, as compared to net borrowings on 
our Credit Facility of $235 million during the year ended December 31, 2022.

Our 2024 capital budget is $150 million to $170 million.  Our capital budgets may be adjusted as business conditions 

warrant.  If natural gas, NGLs and oil prices decline to levels below acceptable levels or costs increase to levels above acceptable 
levels, Antero Resources could choose to defer a significant portion of its budgeted capital expenditures until later periods.  As a 
result, we may also defer a significant portion of our budgeted capital expenditures to achieve the desired balance between sources and 
uses of liquidity and prioritize capital projects that we believe have the highest expected returns and potential to generate consistent 
cash flows.  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  

Credit Facility 

Antero Midstream Partners, as borrower (the “Borrower”), an indirect, wholly owned subsidiary of Antero Midstream 

Corporation, has a senior secured revolving credit facility with a consortium of banks.  The Credit Facility provides for borrowing 
under either Adjusted Term Secured Overnight Financing Rate (“SOFR”) or the Base Rate (as each term is defined in the Credit 
Facility). 

The Credit Facility has lender commitments of $1.25 billion and matures on October 26, 2026; provided that if on 
November 17, 2025 any of the 7.875% senior notes due May 15, 2026 (the “2026 Notes”) are outstanding, the Credit Facility will 
mature on such date.  As of December 31, 2023, we had $630 million of borrowings and no letters of credit outstanding under the 
Credit Facility.   

We have a choice of borrowing at Adjusted Term SOFR or at the base rate.  Principal amounts borrowed are payable on the 

maturity date with such borrowings bearing interest that is payable (i) with respect to base rate loans, quarterly and (ii) with respect to 
SOFR Loans, the last day of each Interest Period (as defined below); provided that if any Interest Period for a SOFR Loan exceeds 
three months, interest will be payable on the respective dates that fall every three months after the beginning of such Interest Period.  
SOFR Loans bear interest at a rate per annum equal to the rate for SOFR rate loans for three or six months (the “Interest Period”) plus 
an applicable margin ranging from 150 to 250 basis points (subject to certain exceptions), depending on the leverage ratio then in 
effect. Base rate loans bear interest at a rate per annum equal to the greatest of (i) the agent bank’s reference rate, (ii) the federal funds 
effective rate plus 50 basis points and (iii) the rate for one month SOFR Rate loans plus 100 basis points, plus an applicable margin 
ranging from 50 to 150 basis points (subject to certain exceptions) depending on the leverage ratio then in effect.

The Credit Facility is guaranteed by our subsidiaries and is secured by mortgages on substantially all of Antero Midstream 
Partners’ and its subsidiaries’ properties. The Credit Facility contains restrictive covenants that may limit our ability to, among other 
things: 

• 

• 

incur additional indebtedness; 

sell assets; 

•  make loans to others; 

•  make investments and acquisitions; 

• 

enter into mergers; 

•  make certain restricted payments; 

• 

• 

incur liens; and 

engage in certain other transactions without the prior consent of the lenders. 

The Credit Facility also requires us to maintain the following financial ratios (subject to certain exceptions): 

• 

• 

• 

a consolidated interest coverage ratio, which is the ratio of our 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 our election (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 rather than the 
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. 

We were in compliance with the applicable covenants and ratios as of December 31, 2023.  

See Note 8—Long-Term Debt to the consolidated financial statements for more information.

redeemed, together with accrued and unpaid interest up to the redemption date.  Prior to such date, we may, in certain circumstances, redeem the notes at a 
redemption price that includes an applicable premium as defined in the indentures to such notes. 

See Note 8—Long-Term Debt to the consolidated financial statements for more information. 

We may, from time to time, seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for 

equity securities, 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.  The amounts involved could be 
material.  See Note 8—Long-Term Debt to the consolidated financial statements for more 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 
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 federal income taxes, but are currently not in 
a cash tax paying position with respect to 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.  As of December 31, 2023, we have recognized a valuation 
allowance of $3 million related to charitable contributions. 

55 

 
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.  

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, 2023, we had $630 million of 
borrowings and no letters of credit outstanding under the Credit Facility.  A 1.0% increase in the Credit Facility interest rate would 
have resulted in an estimated $8 million increase in interest expense for the year ended December 31, 2023.  

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, 2023 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, 2023 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, 2023. 

The effectiveness of our internal control over financial reporting as of December 31, 2023 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, 2022 and 2023, 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, 2023, 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, 
2023, 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, 2022 and 2023, and the results of its operations and its cash flows for each of the years in the three-
year period ended December 31, 2023, 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, 2023 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 

 
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, 2023 was $4 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 14—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, 2022 and December 31, 2023, and the results of the 
Company’s operations and its cash flows for the years ended December 31, 2021, 2022 and 2023.  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, including equity-based compensation. 

Transactions between the Company and Antero Resources have been identified in the consolidated financial statements (see 

Note 4—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 (loss) and the carrying value of that investment on the Company’s balance sheet.  When a distribution is 
received, it is recorded as a reduction to the carrying value of that investment on the balance sheet. 

F-8 

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 assets, 
goodwill 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.  As of December 31, 2022, the book overdrafts included within accounts payable were $3 million.  As of December 31, 
2023, there were no book overdrafts. 

(e)  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.  See Note 6— Property and 
Equipment for further information on property and equipment impairments. 

During the year ended December 31, 2022, the Company acquired certain Marcellus gas gathering and compression assets 

and Utica compression assets.  These transactions were accounted for as asset acquisitions 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 6— Property and 
Equipment for further information on asset acquisitions.

ANTERO MIDSTREAM CORPORATION 
Notes to Consolidated Financial Statements (Continued) 

(f)  Investments in Unconsolidated Affiliates 

The Company uses the equity method to account for its investments in companies if the investment provides the Company 

with the ability to exercise significant influence over, but not control of, the operating and financial policies of the investee.  The 
Company’s consolidated net income includes the Company’s proportionate share of the net income or loss of such companies.  The 
Company’s judgment regarding the level of influence over each equity method investee includes considering key factors such as the 
Company’s ownership interest, representation on the Board of Directors and participation in policy-making decisions of the investee 
and material intercompany transactions.  See Note 14—Investments in Unconsolidated Affiliates. 

(g)  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. 

(h)  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. 

(i)  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 completed during the year ended December 31, 2023. 

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. 

F-10 

ANTERO MIDSTREAM CORPORATION 
Notes to Consolidated Financial Statements (Continued) 

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. 

(j)  Litigation and Other Contingencies 

A liability is recorded for a loss contingency when its occurrence is probable and damages can be reasonably estimated based 
on the anticipated most likely outcome or the minimum amount within a range of possible outcomes.  The Company regularly reviews 
contingencies to determine the adequacy of our accruals and related disclosures.  The ultimate amount of losses, if any, may differ 
from these estimates.  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, 2022 and December 31, 2023, the Company had not recorded any liabilities for litigation, environmental 

or other contingencies. 

(k)  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. 

(l)  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 5—Revenue.   

(m) Equity-Based Compensation 

The Company’s consolidated financial statements include equity-based compensation costs related to awards granted by its 

own plans, as in place before and after March 12, 2019, as well as costs allocated by Antero Resources for grants made prior to 
March 12, 2019.  Costs allocated from Antero Resources were offset to additional paid in capital on the consolidated balance sheet.  
After the first quarter of 2023, the process of allocating equity-based compensation costs from Antero Resources to the Company 
ended.  See Note 4—Transactions with Affiliates for additional information regarding Antero Resources’ allocation of expenses to the 
Company.  For awards granted under its own plan, the Company recognizes compensation cost related to all equity-based awards in 
the financial statements based on the estimated grant date fair value.  The Company is authorized to grant various types of equity-
based compensation awards, including stock options, stock appreciation rights, restricted stock awards, restricted stock unit (“RSU”) 
awards, dividend equivalent awards and other types of awards.  The grant date fair values of such awards are determined based on the 
type of award and may utilize market prices on the date of grant, Black-Scholes option-pricing model, Monte Carlo simulations or 
other acceptable valuation methodologies, as appropriate for the type of equity-based award.  Compensation cost is recognized ratably 
over the applicable vesting or service period.  Forfeitures are accounted for as they occur by reversing the expense previously 
recognized for awards that were forfeited during the period.  See Note 10—Equity-Based Compensation.

Notes to Consolidated Financial Statements (Continued) 

(n)  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. 

The carrying values on the consolidated balance sheets of the Company’s cash and cash equivalents, accounts receivable—
Antero Resources, accounts receivable—third party, other current assets, accounts payable—Antero Resources, accounts payable—
third party, accrued liabilities and, other current liabilities approximate fair values due to their short-term maturities.  See Note 13—
Fair Value Measurement. 

(o)  Recently Adopted or Issued Accounting Standards 

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes.  This ASU removes 

certain exceptions to the general principles in ASC 740, Income Taxes (“ASC 740”) and also simplifies portions of ASC 740 by 
clarifying and amending existing guidance.  It is effective for interim and annual reporting periods after December 15, 2020.  The 
Company adopted this ASU on January 1, 2021, and it did not have a material impact on the Company’s consolidated financial 
statements. 

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.  Early adoption is permitted.  ASU 2023-07 is required to be applied retrospectively 
to all prior periods presented in the financial statements.  The Company is evaluating the impact that ASU 2023-07 will have on the 
consolidated financial statements and its plans for adoption, including the adoption date. 

In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 

2023-09 is intended to improve income tax disclosures primarily through enhanced disclosure of income tax rate reconciliation items, 
and disaggregation of income (loss) from continuing operations, income tax expense (benefit) and income taxes paid, net disclosures 
by federal, state and foreign jurisdictions, among others.  This ASU is effective for annual reporting periods beginning after 
December 15, 2024, although early adoption is permitted.  ASU 2023-07 should be applied on a prospective basis, although 
retrospective application is permitted.  The Company is evaluating the impact that ASC 2023-09 will have on the consolidated 
financial statements and its plans for adoption, including the adoption date and transition method. 

(3)  Intangibles  

All customer relationships are subject to amortization and are amortized over a weighted-average period of 18 years, which 
reflects the remaining economic life of the relationships as of December 31, 2023.  The Company recorded amortization expense of 
$71 million for each of the years ended December 31, 2021, 2022 and 2023. 

The carrying amount of customer relationships were as follows:

Substantially all revenues earned during the years ended December 31, 2021, 2022 and 2023 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 $9 million, $14 million and $18 million during the 
years ended December 31, 2021, 2022 and 2023, 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, 
2021, 2022 and 2023, general and administrative expenses charged to the Company by Antero Resources were $32 million, 
$30 million and $29 million, respectively.  These costs relate to: (i) various business services, including payroll processing, accounts 
payable processing and facilities management, (ii) various corporate services, including legal, accounting, treasury, information 
technology and human resources and (iii) compensation, including certain equity-based compensation.  These expenses are charged to 
the Company based on 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, except costs attributable to noncash equity-based compensation.  For 
further information on equity-based compensation, see Note 10—Equity-Based Compensation. 

(5)  Revenue 

All of the Company’s gathering and compression revenues are derived from operating lease agreements, and all of the 

Company’s water handling revenues are derived from service contracts with customers.  The Company 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 and (iii) the Utica compression agreement.  The 2019 
gathering and compression agreement and Marcellus gathering and compression agreement have initial terms through 2038 and 2031, 
respectively, and the Utica compression agreement has two dedicated areas that expire in 2024 and 2030.  Upon expiration of the 
Marcellus gathering and compression service agreement and the Utica compression agreement, the Company will continue to provide 
gathering and compression services under the 2019 gathering and compression agreement.  Pursuant to the gathering and compression 
agreements, Antero Resources has dedicated substantially all of its current and future acreage in West Virginia, Ohio and 
Pennsylvania to the Company for gathering and compression services.  The Company also has an option to gather and compress 
natural gas produced by Antero Resources on any additional undedicated acreage it acquires during the term of the 2019 gathering and

compression agreement outside of West Virginia, Ohio and Pennsylvania on the same terms and conditions as the 2019 gathering and 
compression agreement.  Upon completion of the initial contract term in 2038, the 2019 gathering and compression agreement will 
continue in effect from year to year until such time as the agreement is terminated, effective upon an anniversary of the effective date 
of the agreement, by either the Company or Antero Resources on or before the 180th day prior to the anniversary of such effective 
date. 

The 2019 gathering and compression agreement included a growth incentive fee program whereby low pressure gathering 
fees would be reduced from 2020 through 2023 to the extent Antero Resources achieved certain quarterly volumetric targets during 
such time.  Antero Resources’ throughput gathered under gathering and compression agreements acquired with the Crestwood assets 
was not considered in the low pressure gathering volume targets.  For the years ended December 31, 2021, 2022 and 2023, Antero 
Resources earned fee rebates of $12 million, $48 million and $52 million, respectively.  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 and the Marcellus gathering and compression agreement includes certain 

fixed fee provisions.  If and to the extent Antero Resources requests that the Company construct new low pressure lines, high pressure 
lines and/or compressor stations, the 2019 gathering and compression agreement contains options at the Company’s election for either 
(i) minimum volume commitments that require Antero Resources to utilize or pay for 75% of the high pressure gathering capacity and 
70% of the compression capacity of such new construction for 10 years or (ii) a cost of service fee that allows the Company to earn a 
13% rate of return on such new construction over seven years, which election is made individually for each piece of equipment placed 
in service.  In addition, the Marcellus gathering and compression agreement provides for a minimum volume commitment that 
requires Antero Resources to utilize or pay for 25% of the compression capacity for a period of 10 years from the in-service date.  All 
lease payments under the minimum volume commitments and cost of service fees are considered to be in-substance fixed lease 
payments under the gathering and compression agreements. 

The Company recognizes lease income from its minimum volume commitments and cost of service fees under its gathering 

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

The Company is party to a water services agreement with Antero Resources, whereby the Company provides certain water 
handling services to Antero Resources within an area of dedication in defined service areas in West Virginia and Ohio.  The initial 
term of the water services agreement runs to 2035.  Upon completion of the initial term in 2035, the water services agreement will 
continue in effect from year to year until such time as the agreement is terminated, effective upon an anniversary of the effective date 
of the agreement, by either the Company or Antero Resources on or before the 180th day prior to the anniversary of such effective 
date.  Under the agreement, the Company receives a fixed fee for fresh water deliveries by pipeline directly to the well site, subject to 
annual CPI-based adjustments.  In addition, the Company also provides other fluid handling services.  These operations, along with 
the Company’s fresh water delivery systems, support well completion and production operations for Antero Resources.  These 
services are provided by the Company directly or through third parties with which the Company contracts.  For these other fluid 
handling services provided by third parties, Antero Resources reimburses the Company’s third-party out-of-pocket costs plus 3%.  For 
these other fluid handling services provided by the Company, the Company charges Antero Resources a cost of service fee. 

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

Transaction Price Allocated to Remaining Performance Obligations 

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

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

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

Contract Balances 

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

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

(b) Asset Acquisitions 

On October 25, 2022, the Company acquired certain Marcellus gas gathering and compression assets from Crestwood for 

$205 million in cash, before closing adjustments.  These assets included 72 miles of dry gas gathering pipelines and nine compressor 
stations with approximately 700 MMcf/d of compression capacity.  The cash consideration for this asset acquisition was allocated to 
land and gathering systems and facilities, included in Property and equipment in the consolidated balance sheets, for $3 million and 
$202 million, respectively. 

Additionally, on December 21, 2022, the Company acquired certain Utica compression assets from EnLink for $10 million in 

cash, before closing adjustments.  These assets included four compressor stations with approximately 380 MMcf/d of compression 
capacity.  The acquired compression assets are interconnected with the Company’s existing low pressure and high pressure gathering 
systems and service Antero Resources’ production.  The cash consideration for this asset acquisition was allocated to gathering 
systems and facilities included in Property and equipment in the consolidated balance sheets.

Notes to Consolidated Financial Statements (Continued) 

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, 2022 and 2023, the Company has recorded a valuation allowance of $3 million. 

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, 2022 and 2023, the Company did not have 
any uncertain tax positions. 

As of December 31, 2023, the Company has U.S. federal and state NOL carryforwards before the effect of income taxes of 
$428 million and $496 million, respectively, which have no expiration date.  During the year ended December 31, 2023, the audit of 
the Company’s 2019 tax year was closed by the IRS with no adjustments.  Tax years 2020 through 2023 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 2019 through 2023.

Antero Midstream Partners, an indirect, wholly owned subsidiary of Antero Midstream Corporation, as borrower (the 

“Borrower”), has a Credit Facility with a consortium of banks.  On October 26, 2021, the Company entered into an amended and 
restated Credit Facility, which is secured by mortgages on substantially all of the Borrower’s and its subsidiaries’ properties.  Lender 
commitments under the Credit Facility were $1.25 billion as of December 31, 2022 and December 31, 2023.  The Credit Facility 
matures on October 26, 2026; provided that if on November 17, 2025 any of the 2026 Notes (as defined below) are outstanding, the 
Credit Facility will mature on such date.  As of December 31, 2023, the Credit Facility had an available borrowing capacity of $620 
million. 

The Credit Facility contains certain covenants including restrictions on indebtedness, and requirements with respect to 

leverage and interest coverage ratios.  The Credit Facility permits distributions to the holders of the Borrower’s equity interests in 
accordance with the cash distribution policy, provided that no event of default exists or would be caused thereby, and only to the 
extent permitted by the Borrower’s organizational documents.  The Borrower was in compliance with all of the financial covenants 
under the Credit Facility as of December 31, 2022 and 2023.

The Credit Facility in effect prior to October 26, 2021 provided for borrowing under either the Base Rate or the Eurodollar 

Rate (as each term is defined in the Credit Facility), and the Credit Facility in effect on and after October 26, 2021 provides for 
borrowing under either Adjusted Term SOFR or the Base Rate (as each term is defined in the Credit Facility).  Principal amounts 
borrowed are payable on the maturity date with such borrowings bearing interest that is payable with respect to (i) base rate loans, 
quarterly and (ii) SOFR Loans at the end of the applicable interest period if three months (or shorter, if applicable), or every three 
months if the applicable interest period is longer than three months.  Interest was payable at a variable rate based on LIBOR or the 
base rate, determined by election at the time of borrowing, plus an applicable margin rate under the Credit Facility agreement in effect 
prior to October 26, 2021.  Interest is payable at a variable rate based on SOFR or the base rate, determined by election at the time of 
borrowing, plus an applicable margin rate under the Credit Facility in effect on and after October 26, 2021.  Interest at the time of 
borrowing is determined with reference to the Borrower’s then-current leverage ratio subject to certain exceptions.  Commitment fees 
on the unused portion of the Credit Facility are due quarterly at rates ranging from 0.25% to 0.375% subject to certain exceptions 
based on the leverage ratio then in effect. 

As of December 31, 2022, the Borrower had outstanding borrowings under the Credit Facility of $782 million with a 

weighted average interest rate of 6.17%.  As of December 31, 2023, the Borrower had outstanding borrowings under the Credit 
Facility of $630 million with a weighted average interest rate of 7.08%.  No letters of credit under the Credit Facility were outstanding 
as of December 31, 2022 and 2023. 

(b)   5.375% Senior Notes Due 2024 

On September 13, 2016, Antero Midstream Partners and its wholly owned subsidiary Finance Corp (the “Issuers”), issued 

$650 million in aggregate principal amount of 5.375% senior notes due September 15, 2024 (the “2024 Notes”) at par.  The 2024 
Notes were recorded at their fair value of $652.6 million as of March 12, 2019, and the related premium of $2.6 million was amortized 
into interest expense over the life of the 2024 Notes.  The Issuers redeemed all $650 million of the 2024 Notes at 102.688% of par on 
June 8, 2021, and recognized a loss of $21 million on the early extinguishment of debt during the year ended December 31, 2021, 
which included the write-off of all unamortized debt premium and issuance costs.  Interest on the 2024 Notes was payable on March 
15 and September 15 of each year. 

(c)  7.875% Senior Notes Due 2026 

On November 10, 2020, the Issuers issued $550 million in aggregate principal amount of 7.875% senior notes due May 15, 
2026 (the “2026 Notes”) at par.  The 2026 Notes are unsecured and effectively subordinated to the Credit Facility to the extent of the 
value of the collateral securing the Credit Facility.  The 2026 Notes are fully and unconditionally guaranteed on a joint and several 
senior unsecured basis by Antero Midstream Corporation, Antero Midstream Partners’ wholly owned subsidiaries (other than Finance 
Corp) and certain of its future restricted subsidiaries.  Interest on the 2026 Notes is payable on May 15 and November 15 of each year.  
Antero Midstream Partners may redeem all or part of the 2026 Notes at any time at redemption prices ranging from 103.938% 
currently to 100.00% on or after May 15, 2025.  If Antero Midstream Partners undergoes a change of control followed by a rating 
decline, the holders of the 2026 Notes will have the right to require Antero Midstream Partners to repurchase all or a portion of the 
2026 Notes at a price equal to 101% of the principal amount of the 2026 Notes, plus accrued and unpaid interest.

Restricted Subsidiary (as defined in the applicable indenture governing the series of Senior Notes) of the Issuer or the sale of all or 
substantially all of its assets) and whether or not the guarantor is the surviving entity in such transaction to a person that is not an 
Issuer or a Restricted Subsidiary of an Issuer, such guarantor will be released from its obligations under its guarantee if the sale or 
other disposition does not violate the covenants set forth in the indentures governing the applicable Senior Notes. 

In addition, a guarantor will be released from its obligations under the applicable indenture and its guarantee, upon the release 

or discharge of the guarantee of other indebtedness under a credit facility that resulted in the creation of such guarantee, except a 
release or discharge by or as a result of payment under such guarantee; 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 in connection with any covenant defeasance, legal defeasance or satisfaction and discharge of the applicable Senior Notes.   

During the years ended December 31, 2021, 2022 and 2023, all of the Company’s assets and operations are attributable to the

The Company’s equity-based compensation includes (i) costs allocated to Antero Midstream by Antero Resources for grants 

made prior to March 12, 2019 pursuant to the Antero Resources Corporation Long-Term Incentive Plan (the “AR LTIP”) and (ii) costs 
related to the Antero Midstream Corporation Long-Term Incentive Plan (the “AM LTIP”).  Antero Midstream’s equity-based 
compensation expense is included in general and administrative expenses, and recorded as a credit to additional paid in capital.   

AR LTIP 

Equity-based compensation expense allocated to Antero Midstream from Antero Resources was $2.1 million, $0.4 million 

and less than $0.1 million for the years ended December 31, 2021, 2022 and 2023, respectively, which includes expense related to the 
Converted AM RSU Awards (as defined below).  All grants made prior to March 12, 2019 were fully amortized and vested during 
2023.  Therefore, there will be no further allocation of equity-based compensation expense from Antero Resources to the Company.  
The Company does not reimburse Antero Resources for noncash equity compensation allocated to it for awards issued under the AR 
LTIP. 

AM LTIP 

Effective March 12, 2019, the Board of Directors of Antero Midstream Corporation (the “Board”) adopted the AM LTIP 

under which awards may be granted to employees, directors, and other service providers of the Company and its affiliates.  The 
Company is authorized to grant up to 15,398,901 shares of AM common stock under the AM LTIP.  The AM LTIP provides for the 
grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), dividend equivalents, other stock-

The total fair value of the Company’s vested equity awards for the years ended December 31, 2021, 2022 and 2023 were 

$12 million, $18 million and $22 million, respectively. 

(b)  Restricted Stock Unit Awards 

RSU awards vest subject to the satisfaction of service requirements.  Expense related to each RSU award is recognized on a 

straight-line basis over the requisite service period of the entire award.  Forfeitures are accounted for as they occur by reversing the 
expense previously recognized for awards that were forfeited during the period.  The grant date fair values of these awards are 
determined based on the closing price of the Company’s common stock on the date of the grant.  The weighted average grant date fair 
value per share for RSUs granted during the years ended December 31, 2021, 2022 and 2023 were $8.71, $11.28 and $10.59, 
respectively. 

The Company’s RSU awards included the unvested outstanding phantom units granted under the Antero Midstream Partners 
Long Term Incentive Plan which were assumed by the Company on March 12, 2019, and converted into 1.8926 RSUs under the AM 
LTIP representing a right to receive shares of the Company’s common stock for each converted phantom unit (all such RSUs, the 
“Converted AM RSU Awards”).  The Converted AM RSU Awards were accounted for as if they were distributed by Antero 
Midstream Partners to Antero Resources.  Therefore, the expense related to the Converted AM RSU Awards was subject to allocation 
by Antero Resources.  All remaining Converted AM RSU Awards vested during the year ended December 31, 2023.

(c)  Performance Share Unit Awards 

In April 2019, 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 
as compared to a targeted ROIC (“2019 ROIC PSUs”).  The number of shares of the Company’s common stock that could be earned 
with respect to the 2019 ROIC PSUs ranged from zero to 200% of the target number of the 2019 ROIC PSUs originally granted.  The 
grant date fair value of these awards was based on the closing price of the Company’s common stock on the date of the grant, 
assuming target achievement of the performance condition.  Expense related to the 2019 ROIC PSUs was 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.  During the 
year ended December 31, 2022, the performance condition for the 2019 ROIC PSU’s was met at 200% of target and 137,712 target 
2019 ROIC PSU’s converted into 275,424 shares of the Company’s common stock.  As of December 31, 2022, there were no 2019 
ROIC PSU’s outstanding. 

In April 2022, 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, 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 grant date fair 
value of these awards was based on the closing price of the Company’s common stock on the date of the grant, assuming target 
achievement of the performance condition.  Expense related to the 2022 ROIC PSUs is recognized based on the number of shares of 
the Company’s common stock that are expected to be issued at the end of the measurement period, and such expense is reversed if the 
likelihood of achieving the performance condition decreases. The likelihood of achieving the performance conditions related to 2022 
ROIC PSU awards was probable as of December 31, 2023. 

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 grant date fair 
value of these awards was based on the closing price of the Company’s common stock on the date of the grant, assuming target 
achievement of the performance condition.  Expense related to the 2023 ROIC PSUs is recognized based on the number of shares of 
the Company’s common stock that are expected to be issued at the end of the measurement period, and such expense is reversed if the 
likelihood of achieving the performance condition decreases.  The likelihood of achieving the performance conditions related to 2023 
ROIC PSU awards was probable as of December 31, 2023. 

The grant date fair value per share for PSUs granted during the years ended December 31, 2022 and 2023 were $11.05 and 

$10.58, respectively.  There were no PSUs granted during the year ended December 31, 2021.

a change of control, or at any time on or after March 12, 2029, the Company may redeem the Series A Preferred Stock at a price equal 
to $1,000 per share, plus any accrued and unpaid dividends, payable in cash; provided that if any shares of the Series A Preferred 
Stock are held by The Antero Foundation at the time of such redemption, the price for redemption of each share of Series A Preferred 
Stock will be the greater of (i) $1,000 per share, plus any accrued but unpaid dividends, and (ii) the fair market value of the Series A 
Preferred Stock.  On or after March 12, 2029, the holder of each share of Series A Preferred Stock (other than The Antero Foundation) 
may convert such shares, at any time and from time to time, at the option of the holder into a number of shares of AM common stock 
equal to the conversion ratio in effect on the applicable conversion date, subject to certain limitations.  The Series A Preferred Stock 
ranks senior to the AM common stock as to dividend rights, as well as with respect to rights upon liquidation, winding-up or 
dissolution of the Company.  Holders of the Series A Preferred Stock do not have any voting rights in the Company, except as 
required by law, or any preemptive rights.

(1)  The potential dilutive effects of these awards were excluded from the computation of net income per common share-diluted because the inclusion of these awards 

would have been anti-dilutive. 

(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 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 awards is anti-dilutive.

(b)   Other Assets and Liabilities 

The carrying values of accounts receivable and accounts payable as of December 31, 2022 and 2023 approximated fair value 

because of their short-term nature.  The carrying value of the amounts under the Credit Facility as of December 31, 2022 and 2023 
approximated fair value because the variable interest rates are reflective of current market conditions. 

(14)  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’s net income includes its proportionate share of the net income of the Joint Venture and Stonewall.  When the 

Company records its proportionate share of net income, it increases equity income in the consolidated statements of operations and 
comprehensive income and the carrying value of that investment on its balance sheet.  When distributions on the Company’s 
proportionate share of net income are received, they are recorded as reductions to the carrying value of the investment on the balance 
sheet and are classified as cash inflows from operating activities in accordance with the nature of the distribution approach under 
FASB ASC Topic 230, Statement of Cash Flows. The Company uses the equity method of accounting to account for its investments in 
the Joint Venture and Stonewall because it exercises significant influence, but not control, over the entities.  The Company’s judgment 
regarding the level of influence over its equity investments includes considering key factors such as its ownership interest, 
representation on the applicable Board of Directors and participation in policy-making decisions of the Joint Venture and Stonewall.

(15)  Contingencies 

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

Clearwater Facility.  

On March 13, 2020, Antero Treatment, a wholly owned subsidiary of the Company, filed suit against Veolia in the district 

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

Veolia and the Antero Defendants each filed partial motions to dismiss and motions for summary judgment directed at certain 

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

On January 3, 2023, the Court found that Antero Treatment had prevailed on its claims for breach of contract and fraud, and 
awarded $242 million in damages to Antero Treatment, plus pre- and post-judgment interest and reasonable costs and attorneys’ fees. 
The Court also found in Antero Defendants’ favor on all of Veolia’s affirmative claims.  On January 27, 2023, the Court entered 
judgment in favor of Antero Treatment in the amount of $309 million in damages, which includes pre-judgment interest.  On April 10, 
2023, the Court issued an order identifying an error in its previously entered judgment, and on May 3, 2023, the Court entered an 
amended final judgment in favor of Antero Treatment in the amount of $280 million in damages, which includes pre-judgment interest 
through April 30, 2023.  Antero Treatment was also awarded costs and attorneys’ fees, the amount of which will be determined in 
separate proceedings.  On May 26, 2023, Veolia filed a notice of appeal of the final judgment.  On June 9, 2023, Antero Treatment 
filed a notice of cross-appeal. 

(16)  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, regulatory 
environment and the expertise required for these operations.  Management evaluates the performance of the Company’s business 
segments based on operating income.  Interest expense is primarily managed and evaluated on a consolidated basis.   

(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.
