FORWARD-LOOKING STATEMENTS

The 2020 Annual Report includes “ forward-looking statements.” Such forward-looking statements are subject to a number of risks and uncertainties, many of which  

are not under Antero Midstream Corporation’s (“Antero Midstream”) control. All statements, except for statements of historical fact, made herein regarding activities,  

events or developments Antero Midstream expects, believes or anticipates will or may occur in the future, such as those regarding Antero Midstream’s cash flow coverage  

expectations, growth opportunities, 2021 and long-term  financial and operational outlooks for Antero Midstream and Antero Resources Corporation (“Antero Resources”),  

future plans and future business lines for processing plants and fractionators, Antero Resources’ estimated production, Antero Resources’ expected future growth and  

Antero Resources’ ability to meet its drilling and development plan, are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and  

Section 21E of the Securities Exchange Act of 1934. Although Antero Midstream believes that the plans, intentions and expectations reflected in or suggested by the  

forward-looking statements are reasonable, there is no assurance that these plans, intentions or expectations will be achieved. Therefore, actual outcomes and results  

could materially differ from what is expressed, implied or forecast in such statements. Antero Midstream cautions you that these forward-looking statements are  subject 

to all of the risks and uncertainties incident to Antero Midstream’s business, most of which are difficult to predict and many of which are beyond the Antero Midstream’s  

control. These risks include, but are not limited to, commodity price volatility, inflation, environmental risks, Antero Resources’ drilling and completion and other operating  

risks, regulatory changes, the uncertainty inherent in projecting Antero Resources’ future rates of production, cash flows and access to capital, the timing of development  

expenditures, impacts of world health events, including the COVID-19 pandemic[, potential shut-ins of production by producers due to lack of downstream demand or  

storage capacity] and the other risks described under the heading “Item 1A . Risk Factors” in Antero Midstream’s Annual Report on Form 10-K for the year ended December  

31, 2020. Any forward-looking statement speaks only as of the date on which such statement is made, and Antero Midstream does not undertake any obligation to correct  

or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law.

For a definition of free cash flow and a reconciliation to its most comparable measure calculated in accordance with GAAP for the year ended December 31, 2020, please  

see “Item 6. Selected Financial Data” in our Annual Report on Form 10-K for the year ended December 31, 2020.

DEAR FELLOW 
SHAREHOLDERS, 

As we look back on 2020, we remember the  
challenging and unprecedented times brought 
by the COVID-19 pandemic. During this difficult  
time, our employees have demonstrated why 
they are the core foundation of our company.  
Their persistent effort and dedication allowed 
Antero Midstream to achieve company records 
across all aspects of our business including  
operational and capital efficiencies and 
peer-leading ESG metrics. Most importantly, 
they delivered these results safely. Despite the  
worldwide disruptions from the pandemic, the 
people of Antero Midstream delivered the 
low-emission hydrocarbons needed to 
produce and transport medical supplies  
and personal protective equipment and to heat 
and power homes and hospitals. They also  
provided access to safer and cleaner energy 
supplies in our communities. As we look  
ahead, we are committed to the health and  
safety of our employees and the communities  
in which we operate. 

ANTERO MIDSTREAM  

  1

In 2020, Antero Midstream quickly adapted 
to the ever-changing operating environment, 
successfully reducing our capital budget 
by over $100 million. This commitment to  
capital discipline coupled with our integrated 
relationship with our primary customer,  
Antero Resources (NYSE: AR), resulted in high  
asset utilization rates and attractive returns 
on our invested capital. Specifically, our 
compression and processing capacity was 90% 
and 100% utilized in 2020, respectively,  
and contributed to our compelling 17% return   
on invested capital. 

As a result of our integrated and just-in-time 
investment strategy, Antero Midstream invested 
$208 million of capital, a 68% reduction   
year-over-year, and generated Adjusted EBITDA 
of $850 million in 2020.

This resulted in an inflection point for Antero  
Midstream’s free cash flow before dividends, 
which totaled $498 million in 2020, compared  
to just $62 million in 2019. This capital flexibility  
and discipline, combined with our Adjusted 
EBITDA growth, resulted in a strong balance  
sheet with a leverage ratio of 3.7x at   
year-end 2020.

ANTERO RESOURCES 
CORPORATION
Antero Resources made tremendous strides in 
improving its financial strength in 2020. Since 
embarking on its asset sale program in late  
2019, Antero Resources successfully raised  
$1.1 billion of committed capital through a series  
of transactions, including a VPP, an overriding 
royalty and drilling partnership. This level of  
counterparty support exemplifies the strong 
endorsement of Antero Resources’ assets and 
positioning. These transactions allowed Antero 
Resources to access the senior unsecured 

ANTERO MIDSTREAM  

  3

debt markets several times in 2020 and 2021,  
raising more than $1.5 billion in proceeds and  
eliminating $2.3 billion of near-term maturities. 
These proactive steps successfully right-sized 
the balance sheet and debt maturity schedule   
at Antero Resources. 

In 2020, Antero’s hedge position and access  
to premium-priced markets through its peer-
leading transportation portfolio allowed 
the company to continue developing its 
resource base and increase its scale despite 
the commodity price downturn. In 2020, 
Antero Resources averaged 3.6 Bcfe/d of net  
production, generating 11% year-over-year net 
production growth. Importantly, at year-end 
2020, Antero Resources was the second largest 
NGL producer and the third largest natural gas 
producer in the U.S.

OUR FRESH WATER DELIVERY 

PIPELINES ELIMINATED MORE 

THAN 471,000 WATER TRUCK 

TRIPS IN 2020.

INTEGRATED MIDSTREAM 
SERVICES
In keeping with the changing activity levels 
of Antero Resources, we at Antero Midstream 
focused our investments primarily in West 
Virginia in the Marcellus Shale, constructing  
34 miles of natural gas gathering pipelines and 
adding 360 MMcf/d of incremental compression 
capacity. As of year-end 2020, we had 468 
miles of natural gas gathering pipelines and 
3.2 Bcf/d of compression capacity. In addition, 
we continued to build out our water handling 
and blending infrastructure footprint. Similar 
to our gathering and compression investment 
philosophy, we continue to organically develop 
the water handling and blending assets that 
support the completion operations of Antero 
Resources. In 2020, our investment in fresh 
water delivery pipelines in the Marcellus and 
Utica Shale plays in West Virginia and Ohio, 
respectively, increased our total fresh water 
delivery network to over 337 miles. This fresh 
water delivery system, the largest in Appalachia,

eliminated more than 471,000 water truck 
trips in 2020, significantly reducing Antero’s 
environmental footprint. 

We continued to utilize our existing processing 
and fractionation infrastructure through our 
50/50 joint venture with MPLX (NYSE: MPLX) 
in the core of the liquids-rich Marcellus and 
Utica Shale plays. As a result of the processing 
capacity build-out in late 2019, the Sherwood 
processing complex in West Virginia is now the 
largest processing complex in North America. 
Importantly, during 2020, our 1.4 Bcf/d of 
JV processing capacity at the Sherwood 
processing complex was 100% utilized while 
our fractionation capacity at the Hopedale 
fractionation complex was 92% utilized.

THE POTENTIAL FOR 2021
The year ahead presents an exciting opportunity 
for Antero Midstream. We will continue to 
leverage our existing infrastructure to again 
generate significant free cash flow before 
dividends and, for the first time, free cash 
flow after dividends. Our capital budget of 
$240 to $260 million is focused on our highest 
rate-of-return projects, thus expanding our 
infrastructure into the core liquids-rich areas in 
the Marcellus and Utica Shales. These projects 
supporting Antero Resources and the drilling 
partnership are expected to drive throughput 
and earnings growth on Antero Midstream’s 
dedicated acreage over the next several years. 
Importantly, we have taken steps to significantly 
de-risk Antero Midstream’s business model 
by transitioning to a self-funding C-Corp that 
internally finances both our capital budget 
and return of capital to shareholders. This 
capital budget and business model allows AM 
to maintain a strong balance sheet and peer-
leading return on invested capital (ROIC).

CORPORATE SUSTAINABILITY
Antero Midstream’s company culture is based 
on core business principles of safety, integrity, 
stewardship of the land and environment,  
and relentless innovation. We take a highly 
proactive approach to develop and implement 
work practices and technologies to safely 
deliver natural gas, natural gas liquids, and oil 
in the most ethical and environmentally and 
socially responsible way possible. In April, we 
established an Environmental, Sustainability, 
and Social Governance Committee of the Board of 
Directors. This Committee provides guidance to 

 
 
 
actions, and maintain our position as a world-
class sustainable energy producer, partner, and 
employer of choice. For additional information 
on Antero Midstream’s peer-leading ESG 
metrics, we encourage our shareholders to view 
our corporate sustainability report, which can be 
found at anteromidstream.com/community-
sustainability. 

OUR SHAREHOLDERS
We continue to appreciate the guidance  
and support from our Board of Directors. We 
thank you, our shareholders, for investing in our 
company and look forward to further success  
in 2021, and for many years to come.

management and the Board on matters relating 
to the identification, evaluation, and monitoring 
of corporate citizenship, environmental 
sustainability, climate change, and social  
and political trends, issues, and concerns. The  
Committee was integral to the development  
of Antero’s 2025 environmental goals. 

Antero Midstream utilizes a Pipeline 
Integrity Program to meet and exceed safety,  
environmental, and integrity expectations  
to protect our workforce, the environment,  
and the communities where we operate. This 
is done through adherence to a set of safety  
management, analytical, operating, and 
maintenance processes. Antero strives to  
protect and maintain healthy and diverse 
ecosystems and communities by implementing 
approaches to avoid, minimize and restore 
environmental impacts. These approaches have 
led to significant reductions in truck traffic on 
community roads, volumes of fresh water used,  
and spills throughout our operations. We also  
recognize the growing concern over climate 
change and are committed to proactively 
manage our business to reduce greenhouse gas 
(GHG) emissions, including methane emissions, 
and limit the environmental impact of our  
operations. Antero Midstream has utilized 
a rigorous leak detection and repair (LDAR)  
program on all of our facilities and pipelines for  
many years. These best practices have resulted  
in our industry-leading GHG intensity and leak 
loss rate numbers. Antero Midstream’s GHG 
performance metrics demonstrate that natural 
gas can live up to its promise as a transition fuel  
and reduce GHG emissions by more than half, as  
compared to coal.

Natural gas is a key component in the energy  
transition and can be produced and transported 
with minimal leakage and loss. As the lightest  
and least GHG intensive hydrocarbon, natural 
gas is expected to play a fundamental role as  
both the U.S. and global economies transition  
to a lower carbon future. Our outstanding ESG  
performance demonstrates our unwavering 
commitment to make every effort to do the  
right thing, accept accountability for our

Some of the information in this Annual Report on Form 10-K may contain “forward-looking statements” within the meaning 

of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of

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. 

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. 

•  The gathering and compression agreement includes 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.  Restrictions on the ability to obtain water may incentivize water recycling efforts by oil and natural 
gas producers, which would decrease the demand for our fresh water delivery services. 

ii 

• 

Increasing attention to environmental, social and governance (“ESG”) matters and conversation 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. 

•  A pandemic, epidemic or outbreak of an infectious disease, such as COVID-19, may materially adversely affect our 

business. 

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. 

•  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. 

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 

Antero Midstream Corporation was originally formed as Antero Resources Midstream Management LLC in 2013 to become 
the general partner of Antero Midstream Partners.  On May 4, 2017, ARMM converted from a limited liability company to a limited 
partnership under the laws of the State of Delaware and changed its name to Antero Midstream GP LP (“AMGP”) in connection with 
its initial public offering. On March 12, 2019, pursuant to the Simplification Agreement, dated as of October 9, 2018, by and among 
AMGP, Antero Midstream Partners and certain of their affiliates (the “Simplification Agreement”), (i) AMGP was converted from a 
limited partnership to a corporation under the laws of the State of Delaware and changed its name to Antero Midstream Corporation 
(the “Conversion”), (ii) an indirect, wholly owned subsidiary of Antero Midstream was merged with and into Antero Midstream 
Partners, with Antero Midstream Partners surviving the merger as an indirect, wholly owned subsidiary of Antero Midstream (the 
“Merger”) and (iii) Antero Midstream exchanged (the “Series B Exchange” and, together with the Conversion, the Merger and the 
other transactions pursuant to the Simplification Agreement, the “Transactions”) each issued and outstanding Series B Unit (the 
“Series B Units”) representing a membership interest in Antero IDR Holdings LLC (“IDR Holdings”) for 176.0041 shares of its 
common stock, par value $0.01 per share. 

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 such area.  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 located primarily in West Virginia and Ohio.  Our assets also include two independent water handling 
systems that deliver fresh water from the Ohio River and several regional waterways.  These water handling systems consist of 
permanent buried pipelines, surface pipelines and fresh water storage facilities, as well as pumping stations and impoundments to 
transport the fresh water throughout the pipelines.  In addition, we also provide fluid handling services for flowback and produced 
water, including blending, storage and transportation operations, which services utilize certain of our permanent buried pipelines and 
surface pipelines.  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. 

We utilize our midstream infrastructure assets to 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 
contracts, limiting our direct exposure to commodity price risk.  As of December 31, 2020, all of Antero Resources’ approximate 582,000 
gross acres (515,000 net acres) are dedicated to us for gathering, compression and water services, except for approximately  135,000 
gross acres subject to third-party gathering and compression commitments.  We also own a 15% equity interest in the gathering system 
of Stonewall Gas Gathering LLC (“Stonewall”) and a 50% equity interest in the Joint Venture to develop processing and fractionation 
assets in Appalachia with MarkWest.  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.  Under its agreements with us and subject to any pre-existing dedications or other third-party commitments, Antero 
Resources has 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.  We also have certain rights of first offer with 
respect to gathering, compression, processing and fractionation services and water services for acreage located outside of the existing 

1 

 
dedicated areas.  The gathering and compression agreement expires in 2038, and the water services agreement expires in 2035.  Both 
agreements  are  subject  to  automatic  annual  renewal  with  rights  by  either  party  to  terminate  on  or  before  the  180 th  day  prior  to  the 
anniversary of such effective date. 

In connection with our entrance into the water services agreement, we agreed to pay Antero Resources (a) $125 million in 

cash if we delivered 176 million barrels or more of fresh water during the period between January 1, 2017 and December 31, 2019 and 
(b) an additional $125 million in cash if we delivered 219 million barrels or more of fresh water during the period between January 1, 
2018 and December 31, 2020.  As of December 31, 2019, we had delivered 176 million barrels of fresh water, which entitled Antero 
Resources to $125 million pursuant to clause (a) above.  In January 2020, Antero Midstream Partners paid Antero Resources $125 
million. In the three-year period ended December 31, 2020, we delivered 163 million of the 219 million barrels of fresh water, and 
therefore, no such payment is due to Antero Resources’ pursuant to clause (b) above. As of December 31, 2020, no additional 
contingent acquisition consideration is expected to be earned.   

Due to the extensive geographic distribution of our water pipeline systems in both West Virginia and Ohio, we are able to 

provide, and have in the past provided, water delivery services to other oil and gas producers operating within and adjacent to Antero 
Resources’ operating area in an effort to further leverage the use of our existing system. 

Operating Segments 

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

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

2020 Capital Investments 

For the year ended December 31, 2020, our total capital spending was $182 million, which included $141 million of expansion 
capital and $41 million of maintenance capital.  We spent an aggregate of $141 million for gathering and compression infrastructure.  
The additional gathering and compression infrastructure included  34 miles of pipelines in the  Appalachian Basin.  Additionally, we 
invested  an  aggregate  of  $41  million  in  water  infrastructure  to  construct  six  miles  of  additional  buried  water  pipelines  and  surface 
pipelines in the Appalachian Basin.  We also invested $25 million in our unconsolidated affiliates. 

2021 Capital Budget  

During 2021, we plan to expand our existing Appalachian Basin gathering, processing and water handling infrastructure to 

accommodate Antero Resources’ development plans.  Antero Resources announced that it plans to operate three drilling rigs and 
complete between 65 and 70 horizontal wells, substantially all of which are expected to be located on acreage dedicated to us.  Antero 
Resources’ announced 2021 drilling and completion capital budget is $590 million.  Our 2021 capital budget is a range of $240 
million to $260 million, which includes approximately $65 million of additional growth capital supporting the increased 
volumes expected from Antero Resources’ drilling partnership in addition to its previously disclosed maintenance capital program for 
2021. 

Our Assets  

Our gathering and compression 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 fresh 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 water handling systems consist of permanent buried pipelines, surface pipelines and fresh water storage facilities, as well 
as pumping stations and impoundments to transport fresh water throughout the systems used to deliver water to Antero Resources’ 
well completions.  Our assets also include other flowback and produced water treatment facilities that we use to provide water 
treatment services to Antero Resources.

As of December 31, 2020, we had the ability to store 5.7 million barrels of fresh water in 37 impoundments.  Additionally, 

we own water blending and storage assets 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, waste water pits 
and a related landfill used for the disposal of salt therefrom (collectively, the “Clearwater Facility”), which we idled in September 
2019. 

Idling of the Clearwater Facility 

On September 18, 2019, we commenced a strategic evaluation of the Clearwater Facility.  Based on the preliminary results of 

our evaluation and ongoing discussions with the Clearwater Facility’s contractor, the Clearwater Facility was idled.  We expect the 
Clearwater Facility to continue to be idled for the foreseeable future.  The decision to idle the Clearwater Facility was driven by its 
inability to operate at its intended specifications.  Accordingly, we recorded impairment charges related to the Clearwater Facility of 
$409 million for property and equipment, $42 million of goodwill and $12 million in customer relationships during the year ended 
December 31, 2019.  Additionally, during the year ended December 31, 2020, we determined that the carrying value of the landfill 
was no longer recoverable resulting in an impairment charge to property and equipment of $7 million.  See Note 4—Clearwater 
Facility Idling to our consolidated financial statements.  During the year ended December 31, 2019 and 2020, we incurred $11 million 
and $15 million, respectively, in facility idling costs for the care and maintenance of the Clearwater Facility.  Since idling the 
Clearwater Facility, we have satisfied our obligation to handle Antero Resources’ flowback and produced water through our blending 
operations and third parties. 

Our Relationship with Antero Resources  

Antero Resources has a 29.2% ownership interest in us as of December 31, 2020.  Antero Resources is our most significant 

customer and is one of the largest producers of natural gas and NGLs in the Appalachian Basin, where it produced, on average, 
3.6 Bcfe/d net (33% liquids) during 2020, an increase of 11% as compared to 2019.  As of December 31, 2020, Antero Resources’ 
estimated net proved reserves were 17.6 Tcfe, which were comprised of 57% natural gas, 42% NGLs and 1% oil.  As of December 31, 
2020, Antero Resources’ drilling inventory consisted of 2,133 identified potential horizontal well locations (approximately 1,531 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 and its production increases.  Antero 
Resources announced its 2021 drilling and completion budget is $590 million, and includes plans to operate three drilling rigs, in the 
Appalachian Basin.  Antero Resources relies significantly on us to deliver the midstream infrastructure necessary to accommodate its 
production growth.  For additional information regarding our contracts with Antero Resources, please read “—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, please read “Item 1A.  
Risk Factors—Risks Related to Our Business.”   

Operational and Managerial Arrangements with Antero Resources 

Gathering and Compression 

Pursuant to the gathering and compression agreement with Antero Resources, Antero Resources has dedicated all of its current 
and future acreage in West Virginia, Ohio and Pennsylvania to Antero Midstream Partners for gathering and compression except for 
acreage attributable to third-party commitments in effect prior to the agreement, or acreage Antero Resources acquires that is subject 
to pre-existing dedications.  In December 2019, we and Antero Resources agreed to extend the initial term of the agreement to 2038 
and established a growth incentive fee program whereby low pressure gathering fees will be reduced from 2020 through 2023 to the 
extent Antero Resources achieves certain volumetric targets.  For a discussion of Antero Resources’ existing third-party commitments

and pre-existing dedications, please read “—Antero Resources’ Existing Third-Party Commitments.”  We also have an option to 
gather and compress natural gas produced by Antero Resources on any acreage it acquires in the future outside of West Virginia, Ohio 
and Pennsylvania on the same terms and conditions.  Under the gathering and compression agreement, we receive a low pressure 
gathering fee per Mcf, a high-pressure gathering fee per Mcf and a compression fee per Mcf, in each case subject to CPI-based 
adjustments.  If and to the extent Antero Resources requests that we construct new high pressure lines and compressor stations, the 
gathering and compression agreement contain options at our election for either (i) minimum volume commitments that require Antero 
Resources to utilize or pay for 75% and 70%, respectively, of the capacity of such new construction for 10 years or (ii) a service fee 
that allows us to earn a 13% rate of return on such new construction over seven years.  Additional high pressure lines and compressor 
stations installed on our own initiative are not subject to these options.  These minimum volume commitments and rate of return 
options on new infrastructure are intended to support the stability of our cash flows.  

Antero Resources achieved all of its low pressure gathering growth incentive targets for 2020 and earned $48 million in fee 
reductions during the year.  The following table summarizes the remaining low pressure gathering growth incentive targets for 2021 
through 2023.  If actual low pressure volumes are below the lowest tier for the respective calendar years, Antero Resources will not 
receive a reduction in low pressure gathering fees.

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 per barrel in West Virginia and Ohio and all other 
locations for fresh water deliveries by pipeline directly to the well site.  Antero Resources also agreed to pay us a fixed fee per barrel 
for wastewater treatment at the Clearwater Facility, which was idled in the third quarter of 2019 and we expect will remain idled for 
the foreseeable future.  Additionally, we provide or manage other fluid handling services for well completion and production 
operations in Antero Resources’ operating areas.  The fees for such services are all subject to CPI adjustments.  In addition, we also 
provide fluid handling services for flowback and produced water, including blending, storage and transportation operations.  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 flowback and produced water services 
provided by third-parties, Antero Resources reimburses our third-party out-of-pocket costs plus 3%.  For flowback and produced 
water 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 NGL Fractionation 

The Joint Venture was formed in February 2017 to develop processing and fractionation assets in Appalachia.  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 NGL 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. For 
additional information, please read “—Antero Resources’ Existing Third-Party Commitments.”  

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.  

Antero Resources’ Existing Third-Party Commitments 

Excluded Acreage 

Antero Resources previously dedicated a portion of its acreage in the Appalachian Basin to certain third parties’ gathering 
and compression services.  We refer to this acreage dedication as the “excluded acreage.”  As of December 31, 2020, the excluded 
acreage consisted of approximately 135,000 of Antero Resources’ existing gross leasehold acreage, which included approximately 602 
of Antero Resources’ 2,133 potential horizontal well locations.  As part of its five year drilling plan, Antero Resources expects to drill 
most of its wells on acreage dedicated to us.  

Other Commitments 

In addition to the excluded acreage, Antero Resources has entered into contracts with certain third-parties that include 

minimum volume commitments for high pressure gathering and/or compression services.  Specifically, those volume commitments 
consist of up to an aggregate of 450 MMcf/d on high pressure gathering pipelines and approximately 560 MMcf/d for compression 
services.  

Acreage Dispositions 

In addition to the excluded acreage and Antero Resources’ other commitments with third parties, each of the gathering and 
compression agreement, water services agreement and right of first offer agreement between Antero Resources and us permit 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.    

Title to Properties 

Our real property is classified into two categories: (1) parcels that we own in fee and (2) 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. 

Seasonality 

Demand for natural gas generally decreases during the spring and fall months and increases during the summer and winter 
months.  However, seasonal anomalies such as mild winters or mild summers sometimes lessen this fluctuation.  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 agreement; (ii) our water handling services 
agreement; and (iii) our right-of-first-offer agreement with Antero Resources for the provision of processing and fractionation 

5 

 
services.  For a description of this contract, please read “—Our Relationship with Antero Resources—Contractual 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 NGL 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 NGL’s final destination, absent a break in the interstate movement.  
Antero Midstream believes that the crude oil and NGL 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 NGL 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 NGL shipment, and 
determine that the shipment is in interstate commerce, the rates for, and terms and conditions of, transportation services provided by 
such facility would be subject to regulation by the FERC under the ICA.  Such FERC regulation could decrease revenue, increase 
operating costs and, depending on the facility in question, could adversely affect Antero Midstream’s results of operations and cash 
flows.  In addition, if any of Antero Midstream’s facilities were found to have provided services or otherwise operated in violation of 
the ICA, this could result in the imposition of administrative and civil remedies and criminal penalties, as well as a requirement to 
disgorge charges collected for such services in excess of the rate established by the FERC. 

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

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

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

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

The Energy Policy Act of 2005 (“EPAct 2005”), amended the NGA and NGPA to prohibit fraud and manipulation in natural 
gas markets.  The FERC subsequently issued a final rule making it unlawful for any entity, in connection with the purchase or sale of 
natural gas or transportation service subject to FERC’s jurisdiction, to defraud, make an untrue statement or omit a material fact or 
engage in any practice, act or course of business that operates or would operate as a fraud.  The FERC’s anti-manipulation rules apply 
to intrastate sales and gathering activities only to the extent that there is a “nexus” to FERC-jurisdictional transactions.  EPAct 2005 
also provided the FERC with the authority to impose civil penalties of up to approximately $1 million (adjusted annually for inflation) 
per day per violation.  In January 2021, FERC issued an order (Order No. 865) 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 $1,307,164 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 “PIPES Act”), and the Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011 (“2011 Pipeline Safety Act”).  
The NGPSA and HLPSA regulate safety requirements in the design, construction, operation and maintenance of natural gas, crude oil 
and NGL pipeline facilities, while the PSIA establishes mandatory inspections for all U.S. crude oil, NGL and natural gas 
transmission pipelines in high-consequence areas or high consequence areas (“HCAs”). 

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.  The regulations require operators, 
including us, to: 

• 

• 

• 

• 

• 

perform ongoing assessments of pipeline integrity; 

identify and characterize applicable threats to pipeline segments that could impact an HCA; 

improve data collection, integration and analysis; 

repair and remediate pipelines as necessary; and 

implement preventive and mitigating actions. 

The 2011 Pipeline Safety Act, among other things, increased the maximum civil penalty for pipeline safety violations and 
directed the Secretary of Transportation to promulgate rules or standards relating to expanded integrity management requirements, 
automatic or remote-controlled valve use, excess flow valve use, leak detection system installation and testing to confirm the material 
strength of pipe operating above 30% of specified minimum yield strength in HCAs.  Consistent with the 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 series of violations.  Those maximum civil penalties have increased to 
$218,647 per violation per day, with a maximum of $2,186,465 for a series of violations, 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 October 2019, PHMSA published three final rules on pipeline safety. The Enhanced Emergency Order Procedures rule (effective 
December 2, 2019) implements an existing statutory authorization for PHMSA to issue emergency orders related to pipeline safety if 
unsafe conditions or practices, or a combination thereof, constitutes or causes an imminent hazard.  The Safety of Hazardous Liquid 
Pipelines rule (effective July 1, 2020) expands PHMSA’s regulation of the safety of hazardous liquid pipelines by extending reporting 
requirements to certain hazardous liquid gravity flow and rural gathering pipelines, establishing new requirements for integrity 
management programs for hazardous liquid pipelines in HCAs and certain other hazardous liquid pipelines and expanding various 
inspection and leak detection requirements.  The Safety of Gas Transmission Pipelines rule (effective July 1, 2020) requires operators 
of certain gas transmission pipelines to reconfirm the Maximum Allowable Operating Pressure (MAOP) of their lines and establishes 
a new “Moderate Consequence Area” for determining regulatory requirements for gas transmission pipeline segments outside of 
HCAs.  The rule also establishes new requirements for conducting baseline assessments and incorporates industry standards and 

7 

 
guidelines as well as new requirements for integrity management programs. We are in the process of assessing the impact of these 
rules on our future costs of operations and revenue from operations, but we do not expect our operations to be affected by these new 
rules any differently than other similarly situated midstream companies. 

PHMSA has also been working on two additional rules related to gas pipeline safety, though we cannot predict when they 
will be 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” is expected to adjust the repair criteria 
for pipelines in HCAs, create new criteria for pipelines in non-HCAs and strengthen integrity management assessment requirements.  
The rule entitled “Safety of Gas Gathering Pipelines” is expected to require all gas gathering pipeline operators to report incidents and 
annual pipeline data and to extend regulatory safety requirements to certain gas gathering pipelines in rural areas. 

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

regulatory actions, including the “Pipeline Safety: Class Location Change Requirements” and the “Pipeline Safety: Safety of Gas 
Transmission and Gathering Pipelines” proposed rulemakings. Congress has also instructed PHMSA to issue final regulations to 
require operators of non-rural gas gathering lines and new and existing transmission and distribution pipeline facilities to conduct 
certain leak detection and repair programs and to require facility inspection and maintenance plans to align with those regulations. 
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; 

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 

8 

 
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, in July 2015, the Ohio Department of Natural Resources issued final rules for horizontal 
drilling well-pad construction.  The Ohio legislature has also adopted laws 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 
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 customer’s 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 

9 

 
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 it 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, 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 
(“NAAQS”), for ozone from 75 to 70 parts per billion, and completed attainment/non-attainment designations in July 2018.  State 
implementation of the revised NAAQS could result in stricter permitting requirements, delay or prohibit our ability to obtain such 
permits, and result in increased expenditures for pollution control equipment, the costs of which could be significant.  Applicable laws 
and regulations require pre-construction permits for the construction or modification of certain projects or facilities with the potential 
to emit air emissions above certain thresholds.  These pre-construction permits generally require use of best available control 
technology (“BACT”), to limit air emissions.  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 (the “Clean Water Act”), 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.  In September 2015, the 
EPA and the Corps issued a final rule defining the scope of the EPA’s and the Corps’ jurisdiction over waters of the U.S. (the 
“WOTUS rule”).  However, on January 23, 2020, the EPA and the Corps finalized the Navigable Waters Protection Rule, which 
narrows the definition of “waters of the United States” relative to the prior 2015 rulemaking.  Legal challenges to both this and prior 
revisions to the definition of WOTUS are ongoing, and it is possible that a new presidential administration could propose a broader 
interpretation of the CWA’s jurisdiction. As a result of these developments, the scope of jurisdiction under the CWA is uncertain at 
this time.  To the extent any rule 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 Clean Water Act Section 404 Nationwide Permit 12 (“NWP 12”) 
10 

 
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 pending appeal and NWP 12 authorizations remain available for certain oil and gas pipeline projects, we cannot predict the 
ultimate outcome of this case and its impacts to the Nationwide Permit 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, the rulemaking may be subject to litigation or to further revision under the Biden Administration. While the full extent and 
impact of the vacatur 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 noncompliance 
with worker health and safety requirements 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, on January 28, 2020, the U.S. District Court for the District of Columbia ordered the USFWS to reconsider its decision 
to list the northern long-eared bat as threatened instead of endangered.  The designation of previously unprotected species as 
threatened or endangered, or redesignation of a threatened species as endangered, in areas where we conduct operations could cause us 
to incur increased costs arising from species protection measures or could result in limitations on our pipeline construction activities or 
the exploration and production activities of Antero Resources, any of which could have an adverse impact on our results of operations. 

Climate Change 

In response to findings that emissions of greenhouse gases (“GHGs”) present an endangerment to public health and the 
environment, the EPA has adopted regulations under existing provisions of the federal Clean Air Act, 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 BACT 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.  In June 2016, the EPA finalized new regulations, known as Subpart OOOOa, that set emissions standards 
for methane and volatile organic compounds 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 

11 

 
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. 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.  However, 

governmental, scientific and public concern over the threat of climate change arising from GHG emissions has resulted in increasing 
political risks in the United States, including climate change related pledges made by President Biden and other public office 
representatives.  These have included promises to pursue actions to limit emissions and curtail the production of oil and gas, such as 
through banning new leases for production of minerals on federal properties, including onshore lands and offshore waters.  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 fossil fuel industry, 
and increased emphasis on climate-related risks across agencies and economic sectors. 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. Additionally, 
President Biden has issued executive orders recommitting the United States to the Paris Agreement and directing the federal 
government to begin formulating the United States’ nationally determined emissions reduction target under the agreement. The 
impacts of this order, and any legislation or regulation promulgated to fulfill the United States commitments under the Paris 
Agreement cannot be predicted at this time.  Litigation risks are also increasing, as a number of cities and other local governments 
have sought to bring suit against the largest oil and natural gas companies in state or federal court, alleging, among other things, that 
such companies created public nuisances by producing fuels that contributed to global warming effects and therefore are responsible 
for damages as a result, or alleging that the companies have been aware of the adverse effects of climate change for some time but 
defrauded their investors or customers by failing to adequately disclose those impacts. 

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 fossil fuel sector. For example, the Federal Reserve recently announced that it 
has joined the Network for Greening the Financial System, a consortium of financial regulators focused on addressing climate-related 
risks in the financial sector. While we cannot predict what policies may result from this, a material reduction in the capital available to 
the fossil fuel 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.  Finally, it should be noted that a number of 
scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have 
significant physical effects, such as increased frequency and severity of storms, droughts and floods and other climatic events; if any 
such effects were to occur, it is uncertain if they would have an adverse effect on our financial condition and operations. 

Although we have not experienced any material adverse effect from compliance with environmental requirements, there is no 

assurance that this will continue.  We did not have any material capital or other non-recurring expenditures in connection with 
complying with environmental laws or environmental remediation matters in 2020, nor do we anticipate that such expenditures will be 
material in 2021. 

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. 

12 

 
 
 
 
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, 
2020, approximately 522 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, wages and benefits.  To foster 
a stronger sense of ownership and align the interests of our personnel with shareholders, we provide long-term incentive programs that 
include restricted stock units, performance share units and cash awards.  Additionally, we offer short-term cash incentive programs 
which are discretionary and are based on individual and company performance factors, among others.  Furthermore, we offer 
comprehensive benefits to our full-time employees working 30 hours or more per week.  To be an employer of choice and maintain 
the strength of our workforce, we consistently assess the current business environment and labor market to refine our compensation 
and benefits programs and other resources available to our personnel.  Among other benefits, these include:  

• 

• 

• 

• 

comprehensive health insurance, including vision and dental; we have not increased employee premiums in over 15 years; 

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

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

competitive paid time off and sick leave programs; and 

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

among others. 

Role Based Support 

We support our employees’ professional development.  To help our personnel succeed in their roles, we emphasize 
continuous formal and informal training and development opportunities.  We disseminate training by department to focus on job and 
area specific training.   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. 

In response to the COVID-19 pandemic, we have implemented significant changes that we believe to be in the best interest of our 

employees, as well as the communities in which we operate, and that comply with government orders.  These include having our 
office employees work from home to the extent they are able and implementing additional safety measures, including required weekly 
testing and other recommended public health measures, for our field and other employees continuing critical on-site work. 

Diversity, Inclusion and Workplace Culture  

We are committed to building a culture where diversity and inclusion are core philosophies across our operations, including, 

but not limited to, our decisions around recruitment, promotion, transfer, leaves of absence, compensation, opportunities for career 
support and advancement, job performance and other relevant job-related criteria.  We embrace an approach to hiring and 

13 

 
 
 
advancement that considers the value of 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; 

14 

 
 
 
•  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.  The low commodity price environment has negatively impacted natural gas producers 
causing some producers in 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. 

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

2020 (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 

15 

 
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 $3.14 per MMBtu to a low of $1.33 per 

MMBtu in 2020, and the daily spot prices for NYMEX West Texas Intermediate crude oil ranged from a high of $63.27 per barrel to a 
low of $(36.98) per barrel during the same period.  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 Northeast region in 
recent years.  Because Antero Resources’ production and reserves predominantly consist of natural gas (approximately 57% 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 on our operations. 

These lower prices have compelled most natural gas and oil producers, including Antero Resources, to reduce the level of 

exploration, drilling and production activity and capital budgets.  For example, Antero Resources’ 2021 capital budget is $625 million, 
compared to 2019 and 2020 capital expenditures of $1.3 billion and $785 million, respectively.  This will have a significant effect on 
our capital resources, liquidity and expected operating results.  Natural gas and oil prices directly affect Antero Resources’ production.  
If prices remain at low levels or decrease further, 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, each of the 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 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. 

16 

 
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.  In response to the COVID-19 pandemic, governments have tried to slow the spread of the virus 
by imposing social distancing guidelines, travel restrictions and stay-at-home orders, which have caused a significant decrease in the 
demand for oil, natural gas and NGLs.  The imbalance between the supply of and demand for these products, as well as the uncertainty 
around the extent and timing of an economic recovery, have caused extreme market volatility and a substantial adverse effect on 
commodity prices.  Also as a result of this imbalance, the industry has experienced and may experience in the future storage capacity 
constraints with respect to oil and certain NGL products.  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, 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, our 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. 

The gathering and compression agreement includes minimum volume commitments only under certain circumstances. 

The gathering and compression agreement includes minimum volume commitments only on new high pressure pipelines and 

compressor stations constructed subsequent to November 2014 at Antero Resources’ request.  The high pressure pipelines and 
compressor stations that existed prior to November 2014 are not supported by minimum volume commitments from Antero 
Resources.  There are no minimum volume commitments on the low pressure pipelines or fresh water distribution pipelines.  Any 
decrease in the current levels of throughput on our gathering, compression and fresh water distribution systems could reduce our 
revenue and cash flows. 

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

The construction of additions or modifications to our existing systems and the construction or purchase of new assets 
involves numerous regulatory, environmental, political and legal uncertainties beyond our control and may require the expenditure of 
significant amounts of capital.  Financing may not be available on economically acceptable terms or at all.  If we undertake these 
projects, we may not be able to complete them on schedule, at the budgeted cost or at all, or they may not operate as designed or at the 
expected levels.  Moreover, our revenues may not increase immediately upon the expenditure of funds on a particular project. For 
example, the construction of our water treatment facility took longer than planned and the facility ran at operating rates below the 
designed capacity and did not meet certain completion milestones under the terms of the construction contract.  As a result, in 
September 2019, we decided to idle such facility for the foreseeable future. Following such idling, we recorded aggregate non-cash 
impairment charges of approximately $463 million and expect to incur additional idling costs going forward.  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.  In addition, 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 

17 

 
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 
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, NGL 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. 

18 

 
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. 

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, or if our customers do not renew or extend their contracts with us, or if 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.  Restrictions on the ability to obtain water may incentivize water recycling efforts by oil and natural gas 
producers, which would decrease the demand for our fresh water delivery services. 

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

activities.  Water is an essential component of natural gas, NGL 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. These improvements allowed Antero Resources to reuse a portion of its produced water through our blending 
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.  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 and societal 

expectations regarding voluntary 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 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 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.   

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. 
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.      

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 are 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 fossil fuel energy companies or the corresponding 
infrastructure projects based on climate change related concerns, which could affect our access to capital for potential growth projects. 

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 provision, gathering and compression of natural gas, 

NGLs and oil and water handling services, including: 

19 

 
 
 
 
• 

• 

• 

• 

• 

• 

• 

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, pump stations, 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. 

A pandemic, epidemic or outbreak of an infectious disease, such as COVID-19, may materially adversely affect our business. 

The global or national outbreak of an infectious disease, such as COVID-19, 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, to address the COVID-19 pandemic 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 

20 

 
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 any such outbreak may also adversely affect our 

business and results of operations.  For example, the effects of COVID-19 and concerns regarding its global spread have negatively 
impacted global demand for crude oil and natural gas, which could continue to contribute to price volatility impacting the price Antero 
Resources receives for its natural gas, NGLs and oil. In addition, COVID-19 could continue to materially and adversely affect the 
demand for and marketability of natural gas, NGLs and oil production and production levels.  Although Antero Resources has not 
been required to curtail or shut-in a portion of its production, it may do so in the future.  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,” the effects of which may be heightened to the extent the COVID-
19 pandemic adversely affects our business and financial results.  

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

Terrorist or cyber-attacks 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.  Strategic targets, 
such as energy-related assets, may be at greater risk of future attacks than other targets in the United States.  Our insurance may not 
protect us against such occurrences.  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, 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.  Deliberate attacks on our assets or our Joint Venture’s assets, security breaches in our systems or infrastructure, or 
the systems or infrastructure of third-parties or the cloud, could lead to the corruption or loss of our proprietary and potentially 
sensitive data, delays in the performance of services for our customers, difficulty in completing and settling transactions, challenges in 
maintaining our books and records, environmental damage, communication interruptions or other operational disruptions and third-
party liabilities.  Cybersecurity attacks in particular are becoming more sophisticated and include, but are not limited to, malicious 
software, ransomware, attempts to gain unauthorized access to data and other electronic security breaches that could lead to 
disruptions in critical systems, unauthorized release of confidential or otherwise protected information and corruption of data. 

As cyber-attacks 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 cyber-attacks.  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.  To date, we have not experienced any material losses 
relating to cyber-attacks; however, there can be no assurance that we will not suffer such losses in the future.  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 

21 

 
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 experienced periods of improvement in 2020, if the high-yield market deteriorates, 
or if we are unable to access alternative means of debt or equity financing on acceptable terms or at all, we may be unable to carry out 
our business plan, which could have a material adverse effect on our financial condition and results of operations and impair our 
ability to service our indebtedness.   

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

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

• 

• 

incur or guarantee additional debt; 

redeem or repurchase units or make distributions under certain circumstances; 

•  make certain investments and acquisitions; 

• 

• 

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 

22 

 
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.  Please read “Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations—
Liquidity and Capital Resources.” 

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

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

• 

• 

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

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

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

• 

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

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

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

Increases in interest rates could adversely affect our business. 

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

interest rates or a reduction in credit rating.  These changes could cause our cost of doing business to increase, limit our ability to 
pursue growth opportunities, reduce cash flow used for our services and place us at a competitive disadvantage.  For example, during 
2020, we had average outstanding borrowings under our revolving credit facility of approximately $1.1 billion, 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 
approximately $11 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. 

23 

 
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. 

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

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

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

transactions.  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 

24 

 
• 

• 

• 

• 

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 only 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) the Sponsor Holders 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) the Sponsor Holders 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 
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. 

25 

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

Certain funds affiliated with Yorktown Partners LLC (“Yorktown”), Paul M. Rady and Glen C. Warren, Jr. (collectively, the 
“Sponsors”) own a significant interest in us.  Messrs. Rady and Warren and an individual affiliated with Yorktown serve as members 
of our Board and the board of directors of Antero Resources.  The Sponsors also own a significant portion of the shares of common 
stock of Antero Resources.  As a result of their investments in Antero Resources, the Sponsors may have conflicting interests with 
other stockholders.  Conflicts of interest could arise in the future between us, on the one hand, and the Sponsors, 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. 

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. 

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 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; 

26 

 
• 

• 

• 

• 

• 

• 

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 NGL 
products. 

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 
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 Corps Clean Water Act Section 404 Nationwide 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 pending appeal and 
NWP 12 authorizations remain available for certain oil and gas pipeline projects, we cannot predict the ultimate outcome of this case 
and its impacts to the nationwide permit 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, the rulemaking may be subject to 
litigation or to further revision under the Biden Administration.  While the full extent and impact of the vacatur 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, in January 2020, EPA and the Corps issued a final rule under the Clean Water Act 
(“CWA”) revising the definition of waters of the United States (“WOTUS”); however, both this and prior revisions to the definition of 
WOTUS are currently subject to litigation, and it is possible that a new presidential administration could propose a broader 
interpretation of the CWA’s jurisdiction.  As a result, the scope of the CWA’s jurisdiction is uncertain at this time.  To the extent any 
rule 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 

27 

 
 
effect on our business, financial condition and results of operations.  Further, the 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.  Please read 
“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 
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 $1,307,164 per day for each violation and disgorgement of profits associated with any violation. 

For more information regarding federal and state regulation of our operations, please read “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 pursuant to the SDWA over certain hydraulic fracturing activities 
involving the use of diesel fuels and issued permitting guidance in February 2014 regarding such activities.  In addition, 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 SDWA 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.  At the state level, several states have adopted or are 
considering adopting regulations that could impose more stringent disclosure and/or well construction requirements on hydraulic 

28 

 
fracturing operations.  For example, in July 2015, the Ohio Department of Natural Resources issued final rules for horizontal drilling 
well-pad construction.  The Ohio legislature has also adopted laws requiring oil and natural gas operators to disclose chemical 
ingredients used to hydraulically fracture wells and to conduct pre-drilling baseline water quality sampling of certain water wells near 
a proposed horizontal well.  Local governments also may seek to adopt ordinances within their jurisdictions regulating the time, place 
and manner of drilling activities in general or hydraulic fracturing activities in particular. 

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

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

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

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

state, provincial and local laws and regulations relating to the discharge of materials into, and protection of, the environment.  
Numerous governmental authorities, such as the EPA and analogous state agencies, have the power to enforce compliance with these 
laws and regulations and the permits issued under them, oftentimes requiring difficult and costly response actions.  These laws and 
regulations may impose various obligations that are applicable to our and our customer’s operations, including the acquisition of 
permits to conduct regulated activities, the incurrence of capital or operating expenditures to limit or prevent releases of materials 
from our or our customers’ operations, the imposition of specific standards addressing worker protection, and the imposition of 
substantial liabilities and remedial obligations for pollution or contamination resulting from our and our customer’s operations.  
Failure to comply with these laws, regulations and permits may result in joint and several, strict liability and the assessment of 
administrative, civil and criminal penalties, the imposition of remedial obligations and the issuance of injunctions limiting or 
preventing some or all of our operations.  Private parties, including the owners of the properties through which our gathering systems 
pass and facilities where wastes resulting from our operations are taken for reclamation or disposal, may also have the right to pursue 
legal actions to enforce compliance, as well as to seek damages for non-compliance, with environmental laws and regulations or for 
personal injury or property damage.  We may not be able to recover all or any of these costs from insurance.  In addition, we may 
experience a delay in obtaining or be unable to obtain required permits, which may cause us to lose potential and current customers, 
interrupt our operations and limit our growth and revenues, which in turn could affect our profitability.  There is no assurance that 
changes in or additions to public policy regarding the protection of the environment will not have a significant impact on our 
operations and profitability.  For example, following the election of President Biden and a Democratic majority in both houses of 
Congress, it is possible that 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.  Please read “Business—Regulation of Environmental and 
Occupational Safety and Health Matters” for more information. 

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 

29 

 
EPA has adopted regulations under existing provisions of the federal Clean Air Act 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.  

In June 2016, the EPA finalized new regulations, known as Subpart OOOOa, that establish emission standards for methane 
and volatile organic compounds from new and modified oil and natural gas production and natural gas processing and transmission 
facilities.  The EPA’s rule package included first-time standards to address emissions of methane from equipment and processes 
across the source category, including hydraulically fractured oil and natural gas well completions.  In addition, the rule package 
extended existing VOC standards under the EPA’s Subpart OOOO to include previously unregulated equipment within the oil and 
natural gas source category.  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. 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 United Nations-sponsored “Paris Agreement” requires member states to individually determine and 

submit non-binding emissions reduction targets every five years after 2020. Although the United States had withdrawn from the Paris 
Agreement, effective January 20, 2021, President Biden has issued executive orders recommitting the United States to the Paris 
Agreement and directing the federal government to begin formulating the United States’ nationally determined emissions reduction 
target under the Paris Agreement. The impacts of this order, and any legislation or regulation promulgated to fulfill the United States 
commitments under the Paris Agreement 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. These have included promises to 
pursue actions to limit emissions and curtail the production of oil and gas, such as through the cessation of leasing public land for 
hydrocarbon development.  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 fossil fuel industry, and increased emphasis on climate-related risks across agencies and economic sectors.  
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. 

Increasingly, fossil fuel companies are also exposed to litigation risks from climate change. A number of cities and other 

local governments have brought suits against the largest fossil fuel companies in state or federal court, alleging, among other things, 
that such companies created public nuisances by producing fuels that contributed to climate change. Suits have also been brought 
against such companies under shareholder and consumer protection laws, alleging that the companies have been aware of the adverse 
effects of climate change but failed to adequately disclose those impacts. 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 fossil fuel sector 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-fossil fuel related sectors. Institutional lenders who 
provide financing to fossil-fuel energy companies have also become more attentive to sustainable lending practices, and some of them 
may elect in future not to provide funding for fossil fuel energy companies. 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 fossil fuel sector. Recently, the Federal Reserve 
announced that it has joined the Network for Greening the Financial System, a consortium of financial regulators focused on 
addressing climate-related risks in the financial sector. A material reduction in the capital available to the fossil fuel 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. 

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

30 

 
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. Additionally, political, litigation and 
financial risks may result in our restricting or cancelling oil and natural gas production activities, incurring liability for damages 
resulting from climate change or impairing our ability to continue operating in an economic manner. One or more of these 
developments could have a material adverse effect on our business, financial condition and results of operation.  Finally, it should be 
noted that a number of scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce 
climate changes that have significant physical effects, such as increased frequency and severity of storms, floods, droughts and other 
extreme climatic events; if any such effects were to occur, they have the potential to cause physical damage to our assets or affect the 
availability of water and thus could have an adverse effect on exploration and production 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.  The regulations require operators to: 

• 

• 

• 

• 

• 

perform ongoing assessments of pipeline integrity; 

identify and characterize applicable threats to pipeline segments that could impact an HCA; 

improve data collection, integration and analysis; 

repair and remediate the pipeline as necessary; and 

implement preventive and mitigating actions. 

The Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011 (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 Pipelines and Hazardous Materials Safety 
Administration (“PHMSA”), finalized rules consistent with the signed act 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 July 2019, those maximum civil penalties were increased to $218,647 and $2,186,465, 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.   

In June 2016, the President of the United States signed into law important new legislation entitled Protecting our 

Infrastructure of Pipelines and Enhancing Safety Act of 2016 (the “PIPES Act”).  The PIPES Act facilitates greater pipeline safety by 
providing PHMSA with emergency order authority, including authority to issue prohibitions and safety measures on owners and 
operators of gas or hazardous liquid pipeline facilities to address imminent hazards, without prior notice or an opportunity for a 
hearing, as well as enhanced release reporting requirements, requiring a review of both natural gas and hazardous liquid integrity 
management programs, and mandating the creation of a working group to consider the development of an information-sharing system 
related to integrity risk analyses.  The PIPES Act also requires that PHMSA publish periodic updates on the status of those mandates 
outstanding from 2011 Pipeline Safety Act, of which several remain to be completed.   

PHMSA regularly revises its pipeline safety regulations.  For example, in October 2019, PHMSA published three final rules 

on pipeline safety. The Enhanced Emergency Order Procedures rule (effective December 2, 2019) implements an existing statutory 
authorization for PHMSA to issue emergency orders related to pipeline safety if unsafe conditions or practices, or a combination 
thereof, constitutes or causes an imminent hazard.  The Safety of Hazardous Liquid Pipelines rule (effective July 1, 2020) expands 
PHMSA’s regulation of the safety of hazardous liquid pipelines by extending reporting requirements to certain hazardous liquid 
gravity flow and rural gathering pipelines, establishing new requirements for integrity management programs for hazardous liquid 
pipelines in HCAs and certain other hazardous liquid pipelines, and expanding various inspection and leak detection 
requirements.  The Safety of Gas Transmission Pipelines rule (effective July 1, 2020) requires operators of certain gas transmission 

31 

 
pipelines to reconfirm the Maximum Allowable Operating Pressure (MAOP) of their lines and establishes a new “Moderate 
Consequence Area” for determining regulatory requirements for gas transmission pipeline segments outside of HCAs.  The rule also 
establishes new requirements for conducting baseline assessments and incorporates industry standards and guidelines as well as new 
requirements for integrity management programs. The rule also includes several requirements that allow operators to notify PHMSA 
of proposed alternative approaches to achieving the objectives of the minimum safety standards.  We are in the process of assessing 
the impact of these rules on our future costs of operations and revenue from operations, but we do not expect our operations to be 
affected by these new rules any differently than other similarly situated midstream companies. 

PHMSA is working on two additional rules related to gas pipeline safety, though we cannot predict when they will be 

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” is expected to adjust the repair criteria 
for pipelines in HCAs, create new criteria for pipelines in non-HCAs and strengthen integrity management assessment requirements.  
The rule entitled “Safety of Gas Gathering Pipelines” is expected to require all gas gathering pipeline operators to report incidents and 
annual pipeline data and to extend regulatory safety requirements to certain gas gathering pipelines in rural areas.  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.  Please read “Business—Pipeline Safety Regulation” for more information. 

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 and Chief Executive Officer, and Glen C. Warren, Jr., President, could have 
a material adverse effect on our business, financial condition and results of operations. 

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

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

Related Parties 

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

All of our officers and certain of our directors are also officers or directors of Antero Resources. Also, as of December 31, 

2020, Antero Resources beneficially owned 29.2% of our outstanding common stock. 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.  Conflicts of interest will arise between Antero Resources and us.  In resolving these actual or apparent conflicts of 
interest, members of our Board may choose strategies that favor Antero Resources over our interests and the interests of our 
stockholders.  These conflicts 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 

32 

 
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 the processing and fractionation services provided by the Joint Venture are supported by minimum volume 
commitments, the gathering and compression agreement includes minimum volumes commitments only on high pressure pipelines 
and compressor stations constructed at Antero Resources’ request after November 2014.  Any decision by Antero Resources to 
operate its assets in a manner that does not support our operations could have a material adverse effect on our business, financial 
condition and results of operations. 

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

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

Income Taxes 

Our future tax liability 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 certain of 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 2023. 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, such as the classification of assets under the income tax depreciation 
rules, the characterization of expenses for income tax purposes, and the tax characterization of the Transactions. Further, any change 
in law may affect our tax position. 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 (in a tax audit or otherwise), or are 
subject to future limitations, our ability to realize these benefits may be limited.  

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 2023. Because our distributions in excess of our earnings and profits decrease a holder’s tax basis in our common stock, such 
excess distributions will result in a corresponding increase in the amount of gain, or a corresponding decrease in the amount of loss, 
recognized by the holder upon the sale of our common stock.   

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

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

33 

 
 
 
 
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. 

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;  

34 

 
 
 
 
         
• 

• 

• 

• 

• 

• 

• 

• 

• 

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 earnings 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.  We 
cannot predict the size of future issuances of our common stock or securities convertible into our common stock or the effect, if any, 
that future issuances and sales of shares of our common stock will have on the market price of our common stock. 

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

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

35 

 
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. 

ITEM 1B.  UNRESOLVED STAFF COMMENTS 

Not applicable. 

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. 

Veolia 

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

Water North America Operating Services, LLC (“Veolia North America”) relating to the Clearwater Facility.  

On March 13, 2020, Antero Treatment LLC (“Antero Treatment”), a wholly owned subsidiary of the Company, filed suit 

against Veolia and Veolia North America in the district court of Denver County, Colorado, 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 design flaws during contract negotiations and continued to conceal and fraudulently misrepresent the 
impact of certain design changes post-execution of the DBA. Antero Treatment is seeking damages from Veolia of at least 
$457 million, which represents the Company’s recorded impairment of the idled Clearwater Facility. In the alternative, Antero 
Treatment sought rescission of the DBA and restitution of, at a minimum, the $230 million out-of-pocket costs paid to Veolia pursuant 
to the DBA. Antero Treatment also asserts related claims against Veolia North America, including equitable claims with respect to 
certain amounts Antero paid to Veolia North America.  

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 asserts breach 
of contract and equitable claims against the Antero Defendants for alleged failures under the DBA, including an allegation that the 
Antero Defendants improperly terminated the DBA to prevent Veolia from earning an approximate $26 million contract balance. The 
Antero Defendants vigorously deny Veolia’s claims. Veolia seeks money damages in an amount not yet specified. Veolia’s suit has 
been consolidated into the action filed by Antero Treatment. 

On April 17, 2020, Veolia, Veolia North America and the Antero Defendants each filed partial motions to dismiss directed at 

certain claims asserted by the opposing party. On July 23, 2020, the Court dismissed Veolia’s equitable claims against the Antero 

36 

 
Defendants and Antero Treatment’s alternative claim for rescission against Veolia. All other claims remain part of the consolidated 
action. The case is set for trial beginning on November 29, 2021.

PURCHASES OF EQUITY SECURITIES  

Common Stock 

We have one class of common equity outstanding, our common stock, par value $0.01 per share.  Our common stock is listed 

on the New York Stock Exchange and traded under the symbol “AM.” On February 12, 2021, shares of our common stock were held 
by 49 holders of record.  The number of holders does not include the holders for whom shares of our common stock are held in a 
“nominee” or “street” name.  In addition, as of February 12, 2021, Antero Resources and its subsidiaries owned 139,042,345 shares of 
our common stock, which represented a 29.2% interest in us.

In August 2019, the Board authorized a $300 million share repurchase program.  During the three months ended December 31, 2020, we did not make any 
repurchases under this program.

Dividends 

On January 20, 2021, the Board declared an aggregate cash dividend on the shares of our common stock of $0.3075 per share 
for the quarter ended December 31, 2020.  The dividend will be payable on February 11, 2021 to stockholders of record as of February 
3, 2021.   

The Board also declared a cash dividend of $138 thousand on shares of our Series A Non-Voting Perpetual Preferred Stock, 

par value $0.01 (the “Series A Preferred Stock”), to be paid on February 16, 2021 in accordance with the terms of the Series A 
Preferred Stock, which are discussed in Note 14—Equity and Earnings Per Common Share to our consolidated financial statements.  
As of December 31, 2020, there were dividends in the amount of $69 thousand accumulated in arrears on our Series A Preferred 
Stock. 

Stock Performance Graph 

The graph below shows the cumulative total shareholder return assuming the investment of $100 on May 4, 2017, the date of 
our initial public offering, in each of our predecessor’s common shares through March 12, 2019 and our common stock thereafter, the 

37 

Standard & Poor’s 500 (“S&P 500”) Index, and 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.  

The information in this Form 10-K appearing under the heading “Stock Performance Graph” is being “furnished” pursuant to 
Item 2.01(e) of Regulation S-K under the Securities Act and shall not be deemed to be “soliciting material” or “filed” with the SEC or 
subject to Regulation 14A or 14C, other than as provided in Item 2.01(e) of Regulation S-K, or to the liabilities of Section 18 of the 
Exchange Act and shall not be deemed incorporated by reference into any filing under the Securities Act of the Exchange Act except 
to the extent that we specifically request that it be treated as such. 

ITEM 6.  SELECTED FINANCIAL DATA 

The following table presents our selected historical financial data, for the periods and as of the dates indicated, for the 

Company and its predecessors. Our predecessor, AMGP, was originally formed as ARMM to become the general partner of Antero 
Midstream Partners and converted into a limited partnership on May 4, 2017 in connection with our IPO. On March 12, 2019, 
pursuant to the Simplification Agreement, we completed the Transactions. 

The Merger has been accounted for as an acquisition by AMGP of Antero Midstream Partners under ASC 805 – Business 

Combinations and accounted for as a business combination, with the assumed assets and liabilities of Antero Midstream Partners 
recorded at their estimated fair value. As a result of the Merger, our historical financial data for previous periods are not comparable to 
the years ended December 31, 2019 and 2020 or to our future financial results. The selected financial data for the years ended 
December 31, 2016, 2017 and 2018 are the financial statements of AMGP and its consolidated subsidiaries, which do not include 
Antero Midstream Partners and its subsidiaries.  Effective March 12, 2019, we began consolidating Antero Midstream Partners and its 
subsidiaries in our consolidated financial statements. As a result, our selected balance sheet financial data presented below at 
December 31, 2019 includes the financial position of Antero Midstream Partners and its subsidiaries, and our selected consolidated 
statements of operations and comprehensive income and cash flows data for the year ended December 31, 2019 include the results of 
operations of Antero Midstream Partners and its subsidiaries beginning on March 13, 2019. The historical selected consolidated 
statement of operations data included herein reflects that, prior to the Merger, AMGP’s only income resulted from distributions made 
on the incentive distribution rights (the “IDRs”) of Antero Midstream Partners and expenses were limited to general and 
administrative expenses and equity-based compensation. Please read “Item 7. Management’s Discussion and Analysis of Financial 
Condition and Results of Operations —Items Affecting Comparability of our Financial Results.” 

Accordingly, we are also presenting our pro forma results of operations for the years ended December 31, 2018 and 

December 31, 2019, which give effect to the adjustments described in Exhibit 99.1 to this Annual Report on Form 10-K.  The pro 
forma information presented below should be read in conjunction with the unaudited pro forma condensed combined financial 
statements, which are filed as Exhibit 99.1 to this Annual Report on Form 10-K and describe the assumptions and adjustments used in 
preparing such information. The pro forma adjustments are based on currently available information and certain estimates and 

38 

assumptions. Therefore, the actual adjustments may differ from the pro forma adjustments. However, management believes that the 
pro forma assumptions provide a reasonable basis for presenting the results of operations on a more meaningful basis. 

The selected statement of operations data and statement of cash flows data for the years ended December 31, 2018, 2019 and 

2020 and the balance sheet data as of December 31, 2019 and 2020 are derived from our audited consolidated financial statements 
included in Item 8 of this Annual Report on Form 10-K. The selected statement of operations data and statement of cash flows data for 
the years ended December 31, 2016 and 2017 and the selected balance sheet data as of December 31, 2016, 2017 and 2018 is derived 
from our audited consolidated financial statements not included in Item 8 of this Annual Report on Form 10-K.  

The selected financial data presented below are qualified in their entirety by reference to, and should be read in conjunction 

with, “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated 
financial statements and related notes included elsewhere in this report:

Non-GAAP Financial Measures  

We use Adjusted EBITDA as an important indicator of our performance. In our presentation of Adjusted EBITDA for the 
year ended December 31, 2020, net income (loss) and the corresponding adjustments reflect our actual results of operations.  In our 
presentation of Adjusted EBITDA for the years ended December 31, 2019 and 2018, net income (loss) and the corresponding 
adjustments reflect our pro forma results of operations. The pro forma information should be read in conjunction with the unaudited 
pro forma condensed combined financial statements, which are filed as Exhibit 99.1 to this Annual Report on Form 10-K. For more 
information, see “Items Affecting Comparability of Our Financial Results.” 

We define Adjusted EBITDA as net income before net interest expense, income tax expense, depreciation, impairment, 

accretion and changes in fair value of contingent acquisition consideration, accretion of asset retirement obligations, equity-based 
compensation, excluding equity in earnings of unconsolidated affiliates, contract restructuring expenses, amortization of customer 
relationships, gains and losses on asset sales and including cash distributions from unconsolidated affiliates. 

We use Adjusted EBITDA to assess: 

• 

• 

• 

the financial performance of our assets, without regard to financing methods capital structure or historical cost basis; 

our operating performance and return on capital as compared to other publicly traded companies in the midstream energy 
sector, without regard to financing or capital structure; and 

the viability of acquisitions and other capital expenditure projects.

Adjusted EBITDA is a non-GAAP financial measure.  The GAAP measure most directly comparable to Adjusted EBITDA is 

net income (loss).  The non-GAAP financial measure of Adjusted EBITDA should not be considered as an alternative to the GAAP 
measure of net income (loss).  Adjusted EBITDA presentations are not made in accordance with GAAP and have important 
limitations as an analytical tool because they include some, but not all, items that affect net income (loss).  You should not consider 
Adjusted EBITDA in isolation or as a substitute for analyses of results as reported under GAAP.  Our definition of Adjusted EBITDA 
may not be comparable to similarly titled measures of other corporations.

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, please 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. 

On March 12, 2019, pursuant to the Simplification Agreement, dated as of October 9, 2018, by and among Antero Midstream 

Partners GP LP (“AMGP”), Antero Midstream Partners and certain of their affiliates (the “Simplification Agreement”) (i) AMGP 
was converted from a limited partnership to a corporation under the laws of the State of Delaware and changed its name to Antero 
Midstream Corporation, (ii) an indirect, wholly owned subsidiary of Antero Midstream Corporation was merged with and into Antero 
Midstream Partners, with Antero Midstream Partners surviving the merger as an indirect, wholly owned subsidiary of Antero 
Midstream Corporation (the “Merger”) and (iii) Antero Midstream Corporation exchanged (the “Series B Exchange” and, together 
with the Conversion, the Merger and the other transactions pursuant to the Simplification Agreement, the “Transactions”) each 
issued and outstanding Series B Unit (the “Series B Units”) representing a membership interest in Antero IDR Holdings LLC (“IDR 
Holdings”) for 176.0041 shares of its common stock, par value $0.01 per share (“AM common stock”).   

The Merger has been accounted for as an acquisition by AMGP of Antero Midstream Partners under ASC 805, Business 
Combinations and accounted for as a business combination, with the assumed assets and liabilities of Antero Midstream Partners 
recorded at fair value.  As a result, the consolidated balance sheets of Antero Midstream Corporation as of December 31, 2019 and 
2020 include the financial position of Antero Midstream Partners and its subsidiaries and the consolidated statements of operations

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 fresh water from the Ohio River and several regional waterways, which portions of these systems are 
also utilized to transport flowback and produced water.  These water handling systems consist of permanent buried pipelines, surface 
pipelines and fresh water storage facilities, as well as pumping stations and impoundments to transport the fresh water throughout the 
pipelines.  These services are provided by us directly or through third-parties with which we contract.  Our assets also include other 
flowback and produced water treatment facilities that we use to provide water treatment services to Antero Resources. 

COVID-19 Pandemic 

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic.  Governments have tried to 

slow the spread of the virus by imposing social distancing guidelines, travel restrictions and stay-at-home orders, which have caused a 
significant decrease in activity in the global economy and the demand for oil, and to a lesser extent, natural gas and NGLs.  Also in 
March 2020, Saudi Arabia and Russia failed to agree to cut production of oil along with the Organization of the Petroleum Exporting 
Countries (“OPEC”), and Saudi Arabia significantly reduced the price at which it sells oil and announced plans to increase production, 
which contributed to a sharp drop in the price of oil.  While OPEC, Russia and other allied producers reached an agreement in April 
2020 to reduce production, oil prices have remained low.  The imbalance between the supply of and demand for oil, as well as the 
uncertainty around the extent and timing of an economic recovery, have caused extreme market volatility and a substantial adverse 
effect on commodity prices. 

As a midstream energy company, we are recognized as an essential business under various federal, state and local regulations 

related to the COVID-19 pandemic.  We have continued to operate as permitted under these regulations while taking steps to protect 
the health and safety of our workers.  We have implemented protocols to reduce the risk of an outbreak within our field operations, 
and these protocols have not reduced Antero Resources’ production and our throughput in a significant manner.  A substantial portion 
of our non-field level employees continue to operate in remote work from home arrangements, and we have been able to maintain a 
consistent level of effectiveness through these arrangements, including maintaining our day-to-day operations, our financial reporting 
systems and our internal control over financial reporting.   

Our midstream assets are located in West Virginia and Ohio to serve the production of natural gas, NGLs and oil in the 

Appalachian Basin, primarily by Antero Resources.  Our operations support well completion and production operations for Antero 
Resources and as such, we are directly impacted by changes in Antero Resources’ operations.  While Antero Resources has seen a 
decrease in the overall demand for its products, demand for natural gas and NGLs has not declined as much as demand for oil, and 
there has not been as substantial an oversupply of natural gas and NGLs as there has been of oil.  Furthermore, the decrease in demand 
for oil has significantly reduced the number of rigs drilling for oil in the continental U.S. and, as a result, estimates of future gas 
supply associated with oil production have declined.  Additionally, the restart of economic activity in Asia and Europe, coupled with 
lower refinery liquefied petroleum gas (“LPG”) production from refineries in the U.S., Europe and Asia during the second quarter, 
provided support for international LPG prices relative to oil.  Further, reductions in OPEC+ and North American oil production and 
the associated NGL volumes are expected to have a supportive effect on propane and butane prices into 2021.  During the year ended 
December 31, 2020, all of our gathering, compression and processing revenues were derived from the production of natural gas. 

Neither our nor Antero Resources’ supply chain has experienced any significant interruptions.  The industry continues to 

experience storage capacity constraints for oil and certain NGL products, and Antero Resources may become subject to those 
constraints if it is not able to sell its production or certain components thereof,  or enter into additional storage arrangements.  The lack 
of a market or available storage for any one NGL product or oil could result in Antero Resources having to delay or discontinue well 
completions and commercial production or shut in production for other products as it has disclosed that it cannot curtail the production 
of individual products in a meaningful way without reducing the production of other products.  Antero Resources has indicated that 

43 

 
the potential impacts of these constraints may include partial shut-in of production, although it is not able to determine the extent of or 
for how long any shut-ins may occur.  Antero Resources has also indicated that because some of its wells produce rich gas, which is 
processed, and some produce dry gas, which does not require processing, it has the ability to change the mix of products that it 
produces and wells that it completes to adjust its production to address takeaway capacity constraints for certain products.  For 
example, Antero Resources has indicated that it has the ability to shut-in rich gas wells and still produce from its dry gas wells if 
processing or storage capacity of NGL products becomes further limited or constrained.  Also, prior to the COVID-19 pandemic, 
Antero Resources had developed a diverse set of buyers and destinations, as well as in-field and off-site storage capacity for its 
condensate volumes.  Since the outbreak of the pandemic, Antero Resources has expanded its customer base and its condensate 
storage capacity within the basin.  However, any production curtailments or shut-ins by Antero Resources or our other customers will 
reduce throughput for our gathering and processing systems.  In addition, if our customers delay or discontinue drilling or completion 
activities, it will reduce the volumes of water that we handle and therefore revenues for our water distribution and handling business. 

In addition, Antero Resources announced in April 2020 that it had reduced its drilling and completion capital budget for 2020 

by approximately 34%.  Antero Resources continues to monitor its five-year drilling plan and has indicated it will make further 
revisions as appropriate.  Reducing its 2020 capital budget may impact production levels in 2021 and forward to the extent fewer wells 
are brought online, which will directly impact our throughput and cash flows for the same time periods. 

During the years ended December 31, 2019 and 2020, we recognized various impairment charges related to certain 
freshwater delivery system assets and fully impaired our Clearwater Facility and goodwill.  Additional impairment charges related to 
our assets may occur if we experience disruptions in operations, decreases in our revenues or other adverse effects of the COVID-19 
pandemic. 

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted.  The CARES Act 

allows corporations with net operating losses (“NOLs”) incurred in 2018, 2019 and 2020 to carry back such NOLs to each of the five 
years preceding the year of the NOLs, beginning with the earliest year in which there was taxable income, and claim an income tax 
refund in the applicable carryback years.  As a result of this NOLs carryback provision in the CARES Act, we were able to recognize 
an income tax refund receivable in March 2020 of $55 million, including $11 million in income tax benefit for the current year and 
$44 million of previously recognized deferred income tax benefit.  As of December 31, 2020, we had received $39 million of this 
refund. 

The COVID-19 pandemic, commodity market volatility and resulting financial market instability are variables beyond our 

control and may adversely impact our generation of funds from operating cash flows, distributions from unconsolidated affiliates, 
available borrowings under our Credit Facility and our ability to access the capital markets. 

Commodity Price Risk 

Our gathering and compression and water services agreements with Antero Resources provide for fixed-fee structures, and 

we intend to continue to pursue additional fixed-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 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. 

2021 Capital Investment 

During 2021, we plan to expand our existing Appalachian Basin gathering, compression and water handling infrastructure to 

accommodate Antero Resources’ announced development plans.  Antero Resources’ announced 2021 consolidated drilling and 
completion budget of $590 million.  Antero Resources announced that it plans to operate three drilling rigs and complete between 65 
and 70 horizontal wells, substantially all of which are located on acreage dedicated to us.  A further or extended decline in commodity 
prices could cause some of the development and production projects of Antero Resources or third parties to be uneconomic or less 
profitable, which could reduce gathering and water handling volumes in our current and future potential areas of operation.  Those 
reductions in gathering and water handling volumes could reduce our revenue and cash flows and adversely affect our ability to return 
capital to holders of our common stock. 

44 

 
Return of Capital Program 

On August 12, 2019, our Board authorized a share repurchase program to opportunistically repurchase up to $300 million of 
shares of our outstanding common stock.  On February 10, 2021, our Board extended this program through June 30, 2023.  During the 
year ended December 31, 2020, we repurchased 8 million shares for approximately $25 million under this program.  We currently 
have approximately $150 million of share repurchase capacity remaining under this program.  

On January 20, 2021, the Board declared a cash dividend on the shares of our common stock of $0.3075 per share for the 
quarter ended December 31, 2020.  The dividend will be payable on February 11, 2021 to stockholders of record as of February 3, 
2021.   

The Board also declared a cash dividend of $138 thousand on the Series A Preferred Stock to be paid on February 16, 2021 in 
accordance with the terms of the Series A Preferred Stock, which are discussed in Note 14—Equity and Earnings Per Common Share 
to our consolidated financial statements 

Sources of Our Revenues 

Our gathering and compression revenues are driven by the volumes of natural gas we gather and compress, and our water 

handling revenues are driven by quantities of fresh water delivered to our customers to support their well completion operations and 
produced water treated.  Pursuant to our long-term contracts with Antero Resources, we have secured long-term dedications covering 
a significant portion of Antero Resources’ current and future acreage for gathering and compression services.  We have also entered 
into a long-term water services agreement covering Antero Resources’ 515,000 net acres in West Virginia and Ohio, with a right of 
first offer on all future areas of operation.  Under the agreement, we receive a fixed fee for all fresh water deliveries by pipeline 
directly to the well site, subject to annual CPI adjustments.  In addition, we also provide fluid handling services for flowback and 
produced water, including blending, storage and transportation operations.  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 flowback and produced water services provided by third-parties, Antero Resources 
reimburses our third-party out-of-pocket costs plus 3%.  For flowback and produced water services provided by us, we charge Antero 
Resources a cost of service fee. The initial term of the water services agreement runs to 2035.  All of Antero Resources’ existing 
acreage is dedicated to us for gathering and compression services except for existing third-party commitments.  Approximately 
135,000 gross leasehold acres characterized by dry gas and liquids-rich production have been previously dedicated to third-party 
gatherers. 

Our gathering and compression operations are substantially dependent upon natural gas and oil 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. 

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, 2020, Antero Resources had disclosed estimated net proved 
reserves 17.6 Tcfe, of which 57% was natural gas, 42% were NGLs and 1% was oil.  As of December 31, 2020, Antero Resources’ 
drilling inventory consisted of 2,133 identified potential horizontal well locations, approximately 1,531 of which were located on 
acreage dedicated to us, providing us with significant opportunity for growth as Antero Resources’ drilling program continues and its 
production increases. 

How We Evaluate Our Operations 

We use a variety of financial and operational metrics to evaluate our performance.  These metrics help us identify factors and 

trends that impact our operating results, profitability and financial condition.  The key metrics we use to evaluate our business are 
provided below. 

Adjusted EBITDA 

We use Adjusted EBITDA as a performance measure to assess the ability of our assets to generate cash sufficient to pay 
interest costs, support indebtedness and return capital to stockholders.  Adjusted EBITDA is a non-GAAP financial measure.  See 
“Item 6. Selected Financial Data—Non-GAAP Financial Measures” below for more information regarding this financial measure, 
including a reconciliation to its most directly comparable GAAP measure.   

45 

 
 
Gathering and Compression Throughput 

We must continually obtain additional supplies of natural gas and oil to maintain or increase throughput on our systems.  Our 

ability to maintain existing supplies of natural gas and oil and obtain additional supplies is primarily impacted by our acreage 
dedication and the level of successful drilling activity by Antero Resources and the potential for acreage dedications with and 
successful drilling by third-party producers.  Any increase in our throughput volumes over the near term will likely be driven by 
Antero Resources continuing its drilling and development activities on its Appalachian Basin acreage.   

Water Handling Volumes 

Our fresh water volumes are primarily driven by hydraulic fracturing activities conducted as part of well completions.  Our 

treatment volumes are primarily driven by produced water volumes, which are a function of Antero Resources’ production.  Other 
fluid handling volumes are driven by hydraulic fracturing activities and produced water volumes.  Antero Resources’ consolidated 
acreage positions allow us to provide fresh water and other fluid handling services for Antero Resources’ completion activities in a 
more efficient manner.  However, to the extent that Antero Resources’ drilling and completion schedule is not met, or Antero 
Resources uses less fresh water and other fluid handling services in its well completion operations than expected (for example, due to 
a reduction in completions), and production declines, our water volumes may decline.   

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 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 fresh water system.  Other water handling costs, which include the 
costs related to water blending, relate to contract services performed by us and third parties.  Our other water handling costs 
consist of labor, monitoring and repair and maintenance costs.  Wastewater treatment costs vary directly with the water 
volumes treated, and the operating efficiency of the Clearwater Facility which was idled in September 2019 for the 
foreseeable future.  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 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.  

Our general and administrative expenses also include equity-based compensation costs related to the Antero Midstream GP 
LP Long-Term Incentive Plan (“AMGP LTIP”) and the Series B Units prior to the Transactions.  Equity-based compensation 
after the Transactions include (i) costs allocated to Antero Midstream Partners by Antero Resources for grants made prior to 
the Transactions pursuant to Antero Resources’ long-term incentive plan, (ii) costs due to Antero Midstream Corporation 
LTIP (the “AM LTIP”) and (iii) Series B Exchange.  As of December 31, 2020, there were no unvested awards related to the 
AMGP LTIP or Series B Exchange.  

• 

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.  In 2019, our impairment expense primarily related to (i) the 
Clearwater Facility, which was idled in the third quarter of 2019 and (ii) the impairment of goodwill associated with the fresh 
water delivery and services reporting unit.  In 2020, our impairment expense primarily related to (i) the impairment of 

46 

 
 
goodwill associated with our gathering and processing reporting unit and (ii) the fresh water delivery assets in the Utica Shale 
region. 

•  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 8—Property and Equipment to our consolidated financial statements for 
additional information on our asset classes and estimated lives of our assets. 

• 

• 

Interest.  From January 1, 2019 through March 12, 2019, interest expense related to interest incurred on borrowings under 
AMGP’s credit facility, which was terminated on March 12, 2019 in connection with the Transactions.  Following the closing 
of the Transactions on March 12, 2019, interest expense represented interest related to: (i) borrowings under our revolving 
credit facility, (ii) borrowings of $650 million under our 5.375% senior notes due September 15, 2024 (the “2024 Notes”), 
(iii) borrowings of $550 million of our 7.875% senior notes due May 15, 2026 (the “2026 Notes”), (iv) borrowings of $650 
million of our 5.75% senior notes due March 1, 2027 (the “2027 Notes”), (v) borrowings of $650 million of our 5.75% senior 
notes due January 15, 2028 (the “2028 Notes”), (vi) operating leases and (vii) amortization of deferred financing costs 
incurred in connection with the revolving credit facility and the issuance of the 2024 Notes, 2026 Notes, 2027 Notes and 
2028 Notes.   

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 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 benefit to the extent our deferred tax assets exceed our 
deferred tax liabilities.  Our deferred tax assets result from temporary differences between tax and financial statement income 
primarily from goodwill impairment and net operating loss carryforwards.  At December 31, 2020, we had approximately 
$211 million of U.S. federal net operating loss carryforwards (“NOLs”), and approximately $315 million of state NOLs.  The 
amount of deferred tax assets considered realizable, however, could change in the near term as we generate taxable income or 
as estimates of future taxable income are reduced.  See Note 9—Income Taxes to our consolidated financial statements for a 
discussion of our deferred tax position and income tax expense. 

Items Affecting Comparability of Our Financial Results 

Our historical financial results discussed below are not comparable to our future financial results primarily as a result of the 

Merger.  The Merger has been accounted for as an acquisition by AMGP of Antero Midstream Partners under ASC 805, Business 
Combinations, and accounted for as a business combination with the acquired assets and liabilities of Antero Midstream Partners 
recorded at estimated fair value.  Effective March 12, 2019, Antero Midstream commenced consolidating Antero Midstream Partners 
and its subsidiaries in the consolidated financial statements of Antero Midstream.  As a result, our consolidated balance sheet as of 
December 31, 2019 includes the financial position of Antero Midstream Partners and its subsidiaries, and our consolidated statements 
of operations and comprehensive income and cash flows for the year ended December 31, 2019 include the results of operations of 
Antero Midstream Partners and its subsidiaries beginning on March 13, 2019.  

The historical consolidated financial statements included herein are the financial statements of Antero Midstream, formerly 

AMGP, which prior to the Merger reflect that AMGP’s only income resulted from distributions made on the IDRs of Antero 
Midstream Partners and expenses were limited to general and administrative expenses and equity-based compensation.  The 
consolidated financial statements for the year ended December 31, 2019 include the results of Antero Midstream Partners and its 
subsidiaries beginning on March 13, 2019.   

Accordingly, in addition to presenting a discussion of our results of operations as reported, we are also presenting our pro 

forma results of operations, which give effect to the adjustments described in Exhibit 99.1 to this Annual Report on Form 10-K.  The 
pro forma information presented below should be read in conjunction with the unaudited pro forma combined financial statements, 
which are filed as Exhibit 99.1 to this Annual Report on Form 10-K and describe the assumptions and adjustments used in preparing 
such information.  The pro forma adjustments are based on currently available information and certain estimates and assumptions.  
Therefore, the actual adjustments may differ from the pro forma adjustments.  However, management believes that the pro forma 
assumptions provide a reasonable basis for presenting the results of operations on a more meaningful basis. 

47 

 
Results of Operations as Reported 

Year Ended December 31, 2019 Compared to Year Ended December 31, 2020  

Revenue and Direct Operating Expenses.  Revenues from Antero Resources and direct operating expenses for the year ended 
December 31, 2019 reflect 294 days of revenue and operating expenses generated by Antero Midstream Partners after the completion 
of the Transactions on March 12, 2019. 

General and administrative expenses.  General and administrative expenses (excluding equity-based compensation expense) 

decreased 12% from $45 million for the year ended December 31, 2019 to $39 million for the year ended December 31, 2020.  The 
decrease was primarily due to cost reduction efforts, partially offset by inclusion of general and administrative expenses of Antero 
Midstream Partners after the completion of the Transactions on March 12, 2019.  Equity-based compensation decreased from $74 
million for the year ended December 31, 2019 to $13 million for the year ended December 31, 2020 due to the 17,353,999 shares of 
Antero Midstream common stock that were issued in exchange for the 98,600 Series B Units then outstanding (the “Exchanged B 
Units”) that were fully vested on December 31, 2019. 

Impairment of goodwill expense.  Impairment of goodwill expense of $340 million for the year ended December 31, 2019 

reflects (i) $42 million of impairment of goodwill expense associated with the Clearwater Facility and (ii) $298 million of impairment 
of goodwill expense associated with our fresh water delivery and services reporting unit.  Impairment of goodwill expense of $575 
million for the year ended December 31, 2020 was associated with our gathering system due to declines in commodity prices and the 
general industry environment. 

Impairment of property and equipment expense.  Impairment of property and equipment expense of $410 million for the year 

ended December 31, 2019 was primarily due to the idling of the Clearwater Facility. Impairment of property and equipment expense 
of $98 million for the year ended December 31, 2020 was primarily due to the impairment of fresh water delivery assets in the Utica 
Shale region. 

Impairment of customer relationships expense.  Impairment of customer relationships expense of $12 million for the year 

ended December 31, 2019 reflects an impairment of the customer relationships that were associated with the idled Clearwater Facility. 

Depreciation expense.  Depreciation expense increased from $96 million for the year ended December 31, 2019 to 
$109 million for the year ended December 31, 2020 as a result of our acquisition of Antero Midstream Partners on March 12, 2019. 

Accretion and change in fair value of contingent acquisition consideration.  Accretion expense of $8 million for the year 

ended December 31, 2019 relates to the contingent consideration payment that was made in January 2020.  No additional contingent 
consideration is expected to be paid. 

Interest expense.  Interest expense increased $37 million from $110 million for the year ended December 31, 2019 to 

$147 million for the year ended December 31, 2020 as a result of the acquisition of Antero Midstream Partners (which included the 
assumption of approximately $2.4 billion of debt) and Antero Midstream Partners’ issuance of the 2028 Notes in June 2019 and 2026 
Notes in November 2020.   

Operating loss.  Total operating loss decreased from a loss of $398 million for the year ended December 31, 2019 to $118 
million for the year ended December 31, 2020.  The decrease was due to (i) higher revenue and lower direct operating expenses and 
general and administrative expenses between periods as a result of the acquisition of Antero Midstream Partners on March 12, 2019 
and cost reduction efforts and (ii)  lower impairment of property and equipment and impairment of customer relationships for the year 
ended December 31, 2020 as compared to the same period in 2019, partially offset by higher impairment of goodwill expense for the 
year ended December 31, 2020 as compared to the same period in 2019.   

Equity in earnings of unconsolidated affiliates.  Equity in earnings of unconsolidated affiliates for the year ended December 
31, 2019 represents AMGP’s equity investment in Antero Midstream Partners from January 1, 2019 through March 12, 2019 and the 
portion of the net income from Antero Midstream Partners’ investments in Stonewall and the Joint Venture, which is allocated to us 
based on our equity interests for the period from March 13, 2019 through December 31, 2019.  Equity in earnings in unconsolidated 
affiliates increased by $35 million from $51 million for the year ended December 31, 2019 to $86 million for the year ended 
December 31, 2020 primarily attributable to an increase in the level of operations at the Joint Venture during the year ended 
December 31, 2020. 

48 

 
Income tax benefit (expense).  Income tax benefit for the year ended December 31, 2019 was $102 million. Income tax 

benefit for the year ended December 31, 2020 was $56 million primarily due to the loss before taxes for the year ended December 31, 
2020 coupled with an $11 million rate benefit related to the carryback of NOLs to prior tax years.  This carryback generated a federal 
income tax receivable of $55 million, of which $39 million had been received as of December 31, 2020. This carryback is a result of a 
provision included in the CARES Act that allows corporations with NOLs incurred in 2018, 2019 and 2020 to carry back such NOLs 
to each of the five years preceding the year of the NOLs, beginning with the earliest year in which there is taxable income, and claim 
an income tax refund in the applicable carryback years.  The income tax receivable account is classified as a current asset on the 
balance sheet. 

Year Ended December 31, 2018 Compared to Year Ended December 31, 2019 

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

Operations” in our 2019 Annual Report on Form 10-K for a discussion of the results of operations for the year ended December 31, 
2018 compared to the year ended December 31, 2019.  

Pro Forma Segment Results of Operations 

Unless the context otherwise requires, references in this “Pro Forma Segment Results of Operations” to the “Company,” 

“we,” “us” or “our” refer to, and the results of operations discussed below relate to, the combined results of Antero Midstream 
Corporation and Antero Midstream Partners as if the Transactions had occurred on January 1, 2019.  

The pro forma segment results of operations and the pro forma operations data for the year ended December 31, 2019 have 

been prepared to give pro forma effect to the Transactions as if they had occurred on January 1, 2019.  The pro forma adjustments are 
based on currently available information and certain estimates and assumptions, including the final purchase price allocation for the 
acquisition of Antero Midstream Partners.  Therefore, the actual adjustments may differ from the pro forma adjustments.  However, 
management believes that the pro forma assumptions provide a reasonable basis for presenting the significant effects of the 
Transactions. 

The pro forma information is for illustrative purposes only.  If the Transactions had occurred on January 1, 2019, operating 

results might have been materially different from those presented in the pro forma financial information.  The pro forma financial 
information should not be relied upon as an indication of operating results that we would have achieved if the Transactions had taken 
place on January 1, 2019.  In addition, future results may vary significantly from the pro forma results reflected herein and should not 
be relied upon as an indication of our future results.  The pro forma information presented below should be read in conjunction with 
the unaudited pro forma combined financial statements, which are filed as Exhibit 99.1 to this Annual Report on Form 10-K.

Discussion of Results of Operations for the Year Ended December 31, 2019 (Pro Forma) Compared to Year Ended December 31, 
2020  

Revenues.  Revenues decreased by 10% from $997 million, including the amortization of customer relationships of $71 

million, for the year ended December 31, 2019 to $901 million, including the amortization of customer relationships of $71 million, 
for the year ended December 31, 2020.  Gathering and processing revenues increased by 6%, from $638 million for the year ended 
December 31, 2019 to $674 million for the year ended December 31, 2020.  Water handling revenues decreased by 39%, from $372 
million for the year ended December 31, 2019 to $226 million for the year ended December 31, 2020.  These fluctuations primarily 
resulted from the following: 

Gathering and Processing 

• 

• 

• 

low pressure gathering revenue decreased $8 million year over year due to $48 million in rebates to Antero Resources 
for achieving certain volumetric targets, partially offset by an increase in throughput volumes of 282 MMcf/d, which was 
due to 108 additional wells connected to our system during the year ended December 31, 2020;  

high pressure gathering revenue increased $25 million year over year due to an increase in throughput volumes of 292 
MMcf/d, primarily as a result of the addition of one new high pressure gathering line placed in service and additional 
wells connected to our system during the year ended December 31, 2020; and 

compression revenue increased $26 million year over year due to an increase in throughput volumes of 335 MMcf/d, 
primarily due to the addition of one new compressor station that was placed in service and additional wells connected to 
our system during the year ended December 31, 2020.

Water Handling  

• 

• 

• 

fresh water delivery revenue decreased $42 million year over year due to a decrease in fresh water delivery of 32 
MBbl/d, as a result of a decrease in the number of wells completed by Antero Resources due to its reduced drilling and 
completion program during the year ended December 31, 2020; 

revenue from the Clearwater Facility decreased $32 million year-over-year from $32 million for the year ended 
December 31, 2019 to zero during the year ended December 31, 2020 due to the idling of the Clearwater Facility in 
September 2019; and 

other fluid handling services revenue decreased $66 million primarily due to a $76 million decrease in services that are 
billed at cost plus 3% as a result of operational efficiencies associated with our flowback and produced wastewater 
services, which commenced in the fourth quarter of 2019, and cost reductions, partially offset by a $10 million increase 
in water blending services.  

Direct operating expenses.  Total direct operating expenses decreased from $261 million for the year ended December 31, 
2019 to $165 million for the year ended December 31, 2020.  Gathering and processing direct operating expenses increased by 7% 
from $53 million for the year ended December 31, 2019 to $57 million for the year ended December 31, 2020.  The increase was 
primarily due to the cost associated with the new compressor station that came online in 2020 as well as higher throughput volumes 
between periods.  Water handling direct operating expenses decreased 48% from $208 million for the year ended December 31, 2019 
to $109 million for the year ended December 31, 2020.  The decrease was primarily due to operational efficiencies associated with 
flowback and produced wastewater services. 

General and administrative (excluding equity-based compensation) expenses.  General and administrative expenses 

(excluding equity-based compensation expense) decreased by 13% from $46 million for the year ended December 31, 2019 to $39 
million for the year ended December 31, 2020 primarily due to cost reduction efforts, partially offset by legal costs associated with the 
Clearwater Facility.  

Equity-based compensation expenses.  Equity-based compensation expenses decreased from $76 million for the year ended 

December 31, 2019 to $13 million for the year ended December 31, 2020 due to the Exchanged B Units that were fully vested on 
December 31, 2019. 

Impairment of goodwill expense.  Impairment of goodwill expense of $340 million for the year ended December 31, 2019 

reflects an impairment of the goodwill that was associated with the Clearwater Facility and the fresh water delivery and services 
reporting unit. Impairment of goodwill expense of $575 million for the year ended December 31, 2020 reflects an impairment of the 
goodwill that was associated with our gathering system due to declines in commodity prices and the general industry environment. 

Impairment of property and equipment expense.  Impairment of property and equipment expense of $417 million for the year 
ended December 31, 2019 was primarily for the idling of the Clearwater Facility and the decommissioning of assets related to a third-
party compressor station. Impairment of property and equipment expense of $98 million for the year ended December 31, 2020 was 
primarily for the impairment of fresh water delivery assets in the Utica Shale region. 

Impairment of customer relationships expense.  Impairment of customer relationships expense of $12 million for the year 

ended December 31, 2019 reflects an impairment of the customer relationships that were associated with the Clearwater Facility. 

Depreciation expense.  Total depreciation expense decreased by 10%, from $120  million for the year ended December 31, 
2019 to $109 million for the year ended December 31, 2020.  The decrease was primarily due to assets that were impaired during the 
third quarter of 2019 and the first quarter of 2020, partially offset by additional gathering, compression and water handling assets 
placed in service in 2020.  

Accretion and change in fair value of contingent acquisition consideration.  Accretion expense of $10 million for the year 
ended December 31, 2019 relates to the contingent consideration payment that was made in January 2020.  No additional contingent 
consideration is expected to be paid. 

Interest expense.  Interest expense increased by 13%, from $131 million for the year ended December 31, 2019 to $147 

million for the year ended December 31, 2020 primarily due to an increase in interest expense incurred on (i) higher borrowings under 
the Credit Facility during 2020, (ii) the 2027 Notes that were issued during the first quarter of 2019, (iii) the 2028 Notes that were 
issued during the second quarter of 2019 and (iv) the 2026 Notes that were issued during the fourth quarter of 2020. 

53 

 
Operating income (loss).  Total operating loss was $296 million and $118 million the year ended December 31, 2019 and 

2020, respectively. Gathering and processing operating income was $493 million for the year ended December 31, 2019.  Gathering 
and processing operating loss was $48 million for the year ended December 31, 2020 primarily due to an impairment of goodwill. 
Water handling operating loss was $708 million for the year ended December 31, 2019  and $61 million for the year ended December 
31, 2020 primarily due to impairment charges related to the Clearwater Facility and fresh water delivery assets in the Utica Shale 
region in 2019 and 2020, respectively. 

Equity in earnings of unconsolidated affiliates.  Equity in earnings in unconsolidated affiliates increased by 39%, from 
$62 million for the year ended December 31, 2019 to $86 million for the year ended December 31, 2020.  Equity in earnings of 
unconsolidated affiliates represents the portion of the net income from our investments in Stonewall and the Joint Venture, which is 
allocated to us based on our equity interests.  The increase is primarily attributable to an increase in the level of operations at the Joint 
Venture for the year ended December 31, 2020.  

Net income (loss).  Net loss was $285 million for the year ended December 31, 2019 primarily due to the impairments of 

property and equipment, goodwill and customer relationship for the Clearwater Facility.  Net loss was $123 million for the year ended 
December 31, 2020 primarily due to impairment of goodwill associated with our gathering system and impairment of property and 
equipment of our freshwater delivery assets in the Utica Shale region. 

Pro Forma Adjusted EBITDA.  Pro Forma Adjusted EBITDA increased by 2%, from $830 million for the year ended 

December 31, 2019 to $850 million for the year ended December 31, 2020.  The increase was primarily due to increased throughput 
and decreased direct operating expenses.  For a discussion of the non-GAAP financial measure Pro Forma Adjusted EBITDA, 
including a reconciliation to its most directly comparable financial measure calculated and presented in accordance with GAAP, read 
“Item 6. Selected Financial Data—Non-GAAP Financial Measures.” 

Capital Resources and Liquidity as Reported 

Sources and Uses of Cash 

Capital resources and liquidity are provided by operating cash flows, cash on our balance sheet, borrowings under the Credit 

Facility and capital market transactions.  We expect that the combination of these capital resources will be adequate to meet our 
working capital requirements, capital expenditures program, expected quarterly cash dividends and share repurchases under our share 
repurchases program for at least the next 12 months. 

In the year ended December 31, 2020, we paid dividends of $1.23 per share, or a total of $590 million, to holders of our 

common shares or common stock, as applicable, and we paid $550 thousand of dividends on our Series A Preferred Stock.  On 
January 20, 2021, the Board declared a cash dividend on the shares of our common stock of $0.3075 per share for the quarter ended 
December 31, 2020 to be paid on February 11, 2021 to stockholders of record as of February 3, 2021.  The Board also declared an 
aggregate cash dividend of $138 thousand on our Series A Preferred Stock to be paid on February 16, 2021.   As of December 31, 
2020, there were dividends in the amount of $69 thousand accumulated in arrears on our Series A Preferred Stock.

Operating Activities.  Net cash provided by operating activities was $622 million and $753 million for the years ended 
December 31, 2019 and 2020, respectively.  The increase in net cash provided by operating activities for the year ended December 31, 
2020 compared to the year ended December 31, 2019 was primarily the result of higher gathering and processing revenues, lower

direct operating and general and administrative costs and increased cash flows associated with the Merger between periods, partially 
offset by an increase in Clearwater Facility idling costs in 2020. 

Investing Activities.  Net cash flows used in investing activities was $526 million and $219 million for the years ended 
December 31, 2019 and 2020, respectively.  The decrease in cash flows used in investing activities was due to a (i) $129 million 
decrease in investments made in unconsolidated affiliates, (ii) $109 million decrease in additions to our gathering system and (iii) $86 
million decrease in additions to our water handling system.  Additionally, cash flows provided by investing activities for the year 
ended December 31, 2019 included $620 million of cash received upon the acquisition of Antero Midstream Partners LP, which 
amount was borrowed by Antero Midstream Partners under the Credit Facility to fund, in part, $599 million of cash paid to Antero 
Midstream Partners unitholders as consideration in the Merger. 

Financing Activities.  Net cash used in financing activities was $98 million and $535 million for the years ended December 
31, 2019 and 2020, respectively.  Net cash used in financing activities for the year ended December 31, 2020 included: (i) issuance of 
the 2026 Notes of $550 million; (ii) total dividends to our common stockholders and preferred stockholders of $590 million; (iii) $346 
million in net payments on the Credit Facility; (iv) $125 million (net of $8 million reflected in the cash flows provided by operating 
activities related to the accretion of fair value) paid to Antero Resources for the fair value of contingent acquisition consideration at 
the date of acquisition; (v) $25 million of common stock repurchases; and (vi) $6 million in deferred financing costs payments 
associated with the issuance of the 2026 Notes.  Net cash used in financing activities for the year ended December 31, 2019 included: 
(i) issuance of the 2028 Notes of $650 million; (ii); total distributions or dividends to our common stockholders, holders of Series B 
Units and preferred stockholders of $496 million; (iii) $125 million in repurchases of common stock; (iv) net payments on the Credit 
Facility of $116 million and (v) $9 million of payments for deferred financing.  

Year Ended December 31, 2018 Compared to Year Ended December 31, 2019 

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

Resources and Liquidity” in our Annual Report on Form 10-K for the year ended December 31, 2019 for a discussion of the cash 
flows for the year ended December 31, 2018 compared to the year ended December 31, 2019. 

2020 Capital Investments and 2021 Capital Budget 

Antero Midstream Partners’ capital spending for the year ended December 31, 2020 included investing activities of (i) $141 

million to our gathering system, (ii) $41 million to our water handling system and (iii) $25 million invested in our Joint Venture. 

The Board approved a 2021 capital budget with a range of $240 million to $260 million, which includes approximately $65 

million of additional growth capital supporting the increased volumes expected from Antero Resources’ drilling partnership in 
addition to its previously disclosed maintenance capital program for 2021.  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 near-term 
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. 

Debt Agreements  

Credit Facility 

Antero Midstream Partners, as borrower (the “Borrower”), entered into a senior secured revolving credit facility (the “Credit 
Facility”) with a consortium of banks on October 26, 2017.  The Credit Facility includes fall away covenants and lower interest rates 
that are triggered if and when the Borrower elects to enter into an Investment Grade Period (as defined in the Credit Facility).  The 
Credit Facility provides for borrowing under either the Eurodollar Rate or the Base Rate (as each term is defined in the Credit 
Facility). 

The Credit Facility has lender commitments of $2.13 billion and matures on October 26, 2022.  As of December 31, 2020, we 

had $614 million of borrowings and no letters of credit outstanding under the Credit Facility. 

55 

 
We have a choice of borrowing in Eurodollars 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 
Eurodollar loans, the last day of each Interest Period (as defined below); provided that if any Interest Period for a Eurodollar loan 
exceeds three months, interest will be payable on the respective dates that fall every three months after the beginning of such Interest 
Period. Eurodollar loans bear interest at a rate per annum equal to the LIBOR Rate administered by the ICE Benchmark 
Administration for one, two, three, six or, if available to the lenders, twelve months (the “Interest Period”) plus an applicable margin 
ranging from 125 to 225 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 Eurodollar loans plus 100 basis points, plus an applicable margin ranging from 25 to 125 
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; 

• 

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, 2020.

Critical Accounting Policies and Estimates  

The following discussion relates to the critical accounting policies and estimates for both the Company and our Predecessor.  

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.  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.  Certain accounting policies involve judgments and uncertainties to such an extent that 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 carrying values of assets and liabilities that are not readily apparent from other sources.  Actual results may differ from these 
estimates and assumptions used in preparation of our financial statements.  We provide expanded discussion of our more significant 
accounting policies, estimates and judgments below.  We believe these accounting policies reflect our more significant estimates and 
assumptions used in preparation of our financial statements.  See Note 2—Summary of Significant Accounting Policies to our 
consolidated financial statements for a discussion of additional accounting policies and estimates made by management. 

Fair Value Measurement 

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

framework for measuring fair value, and sets forth disclosure requirements 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 we estimate 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.  
Our 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.  

Business Combination 

We recognize and measure the assets acquired and liabilities assumed in a business combination based on their estimated fair 

values at the acquisition date, with any remaining difference recorded as goodwill.  For acquisitions, management engages an

independent valuation specialist to assist with the determination of fair value of the assets acquired, liabilities assumed and goodwill, 
based on recognized business valuation methodologies.  If the initial accounting for the business combination is incomplete by the end 
of the reporting period in which the acquisition occurs, an estimate will be recorded.  Subsequent to the acquisition, and not later than 
one year from the acquisition date, we will record any material adjustments to the initial estimate based on new information obtained 
that would have existed as of the acquisition date.  An adjustment that arises from information obtained that did not exist as of the date 
of the acquisition will be recorded in the period of the adjustment.  Acquisition-related costs are expensed as incurred in connection 
with each business combination. 

We accounted for the Transactions under the acquisition method of accounting and estimated the fair value of assets acquired 

and liabilities assumed at March 12, 2019.  In connection with the Transactions, the Company, among other things, issued shares of 
common stock valued at the closing market price of the common shares at the effective time of the Transactions, which was a Level 1 
measurement.  

We used the discounted cash flow approach, which is an income statement technique, to estimate the fair value of the 
customer relationships and investments in unconsolidated affiliates using a weighted-average cost of capital of 14.1%, which is based 
on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair value hierarchy.  We also 
used this approach in combination with the cost approach to estimate the fair value of property and equipment whereby certain 
property and equipment was adjusted for recent purchases of similar items, economic and functional obsolescence, location, normal 
useful lives and capacity (if applicable).  To estimate the fair value of the long-term debt, we used Level 2 market data inputs.  

Goodwill 

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the acquisition 

of a business.  We test goodwill for impairment annually in the fourth quarter and when events or changes in circumstances indicate 
that the fair value of a reporting unit with goodwill has been reduced below its carrying value.  The impairment test requires allocating 
goodwill and other assets and liabilities to reporting units.  The fair value of each reporting unit is determined and compared to the 
carrying value of the reporting unit.  The fair value is 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.  If the fair value of the reporting unit is less than the carrying value, including goodwill, the excess of the book 
value over the fair value of goodwill is charged to net income as an impairment expense. 

We utilized a combination of approaches to estimate the fair value of our assets including the discounted cash flow approach, 

comparable company method and the cost approach, whereby certain property and equipment was adjusted for recent purchases of 
similar items, economic and functional obsolescence, location, normal useful lives and capacity (if applicable).  We performed our 
fourth quarter of 2019 and first quarter of 2020 quantitative analysis using a weighted-average cost of capital of 10.0% and 18.0%, 
respectively, which is based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the 
fair value hierarchy. 

Property and Equipment 

Property and equipment primarily consists of gathering pipelines, compressor stations and the Clearwater Facility.  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.   

We utilized a discounted cash flow approach to estimate the fair value of our assets.  We performed our first quarter of 2020 

quantitative analysis using a weighted-average cost of capital of 19.0%, which is based on significant inputs not observable in the 
market, and thus represents a Level 3 measurement within the fair value hierarchy. 

Contingent Acquisition Consideration 

In connection with our September 2015 acquisition of certain water treatment assets, we agreed to pay Antero Resources 
(a) $125 million in cash if we delivered 176 million barrels or more of fresh water during the period between January 1, 2017 and 
December 31, 2019 and (b) an additional $125 million in cash if we deliver 219 million barrels or more of fresh water during the 
period between January 1, 2018 and December 31, 2020.  This contingent consideration liability is valued based on Level 3 inputs 
related to the expected average volumes and weighted average cost of capital and was recorded at the time of such acquisition in 

58 

 
accordance with accounting guidance for business combinations.  In January 2020, Antero Midstream Partners paid Antero Resources 
$125 million and, as of December 31, 2020, no additional contingent acquisition consideration was earned.  

General and Administrative and Equity-Based Compensation Costs 

General and administrative costs are charged or allocated to us based on the nature of the expenses and are allocated based on 
our proportionate share of Antero Resources’ gross property and equipment, capital expenditures and labor costs, as applicable.  These 
allocations are based on estimates and assumptions that management believes are reasonable. 

Equity-based compensation grants are measured at their grant date fair value and related compensation cost is recognized 
over the vesting period of the grant.  Compensation cost for awards with graded vesting provisions is recognized on a straight-line 
basis over the requisite service period of each separately vesting portion of the award.  Estimating the fair value of each award 
requires management to apply judgment. 

Equity-based compensation expenses that are subject to allocation as described in “—Principal Components of our Cost 
Structure,” are allocated to us based on our proportionate share of Antero Resources’ labor costs.  These allocations are based on 
estimates and assumptions that management believes are reasonable. 

New Accounting Pronouncements 

There were no new accounting pronouncements issued during the year ended December 31, 2020 that had or are expected to 

have a material effect on the Company’s financial reporting.  

Off-Balance Sheet Arrangements 

As of December 31, 2020, we did not have any off-balance sheet arrangements. 

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 structures, and 

we intend to continue to pursue additional fixed-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 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, 2020, we had $614 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 $11 million increase in interest expense for the year ended December 31, 2020.  

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. 

59 

 
   
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 continue 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 ensure that information 
required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, 
within the time periods specified in the SEC’s rules and forms.  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, 2020 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, 2020 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. 

60 

 
 
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, 2020. 

The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by KPMG LLP, 

an independent registered public accounting firm which also audited our consolidated financial statements as of and for the year ended 
December 31, 2020, 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, 2019 and 2020, the related consolidated statements of operations and comprehensive income (loss), partners’ capital 
and stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2020, 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, 2020, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. We have audited the accompanying consolidated balance sheets of Antero 
Midstream Corporation and subsidiaries (the Company) as of December 31, 2019 and 2020, the related consolidated statements of 
operations and comprehensive income (loss), partners’ capital and stockholders’ equity, and cash flows for each of the years in the 
three-year period ended December 31, 2020, 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, 2020, 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, 2019 and 2020, and the results of its operations and its cash flows for each of the years in the three-
year period ended December 31, 2020, 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, 2020 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 

F-2 

 
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. 

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 Matters 

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial 
statements that were communicated or required to be communicated to the audit committee and that: (1) relate 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 critical audit matters 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 matters below, providing separate opinions on the 
critical audit matters or on the accounts or disclosures to which they relate. 

Lease classification for ongoing modifications to the gathering and compression assets   

As discussed in Note 7 to the consolidated financial statements, the Company determined that the gathering and compression 
agreement with Antero Resources Corporation is an operating lease. The Company continues to expand its gathering and 
compression system to serve its customer and, as a result, the minimum volume commitments and the lease payments increase for 
the expanded system. The increases in volume commitments and lease payments are modifications of the agreement that require 
evaluation of the lease classification. 

We identified the evaluation of lease classification for ongoing modifications to the gathering and compression assets as a critical 
audit matter. The evaluation of lease classification for these modified leases, including evaluating the economic life as a key 
estimate, requires significant judgment. 

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 over the Company’s process for identifying lease modifications and evaluating 
lease classification for those modifications, including the review and approval of the Company’s lease modifications and the 
Company’s evaluation of the lease classification. We evaluated the Company’s accounting memoranda and documentation 
underlying the accounting conclusions reached, including application of relevant accounting guidance in regard to the 
modification accounting and subsequent lease classification. We evaluated the economic life used in the Company’s 
determination of lease classification by comparing it to relevant industry publications. We evaluated fixed assets that are placed in 
service for new minimum volume commitments which would require reassessment of the lease. 

Impairment of Utica fresh water assets   

As discussed in Note 8 to the consolidated financial statements, 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.  An impairment 
loss is recognized if the undiscounted future cash flow projections for the assets being assessed are less than their carrying value. 
If the carrying values of the assets are deemed not recoverable, the carrying values are reduced to their estimated fair values based 
on discounted cash flows, which includes forecasted EBITDA and discount rate assumptions.  During the year ended December 
31, 2020 the Company recorded an impairment related to its Utica fresh water assets of $89 million. 

We identified the evaluation of the impairment of Utica fresh water assets as a critical audit matter. There was a high degree of 
subjectivity in evaluating the key assumptions used to determine the fair value of the Utica fresh water assets. The Company used 
a discounted cash flow model to determine the fair value of the Utica fresh water assets which included the key assumptions of 
forecasted EBITDA and the discount rate. 

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested 
the operating effectiveness of certain internal controls over the Company’s process of estimating the fair value of Utica fresh 
water assets, including controls related to the selection of the key assumptions used to determine the fair value of the Utica fresh 

F-3 

water assets. We evaluated the Company’s forecasted EBITDA by comparing it to the Company’s historical performance. To 
assess the Company’s ability to forecast, we compared the Company’s historical EBITDA forecasts to actual results. In addition, 
we involved valuation professionals with specialized skills and knowledge who assisted in: 

• 

• 

• 

evaluating the approach used to value the Utica fresh water assets 

evaluating the Company’s discount rate applied in the valuation of the Utica fresh water assets by comparing the Company’s 
inputs to publicly available data for comparable entities 

testing the estimate of the Utica fresh water assets fair value using the Company’s cash flow assumptions and discount rate 
and comparing the results to the Company’s fair value estimate. 

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

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements 

Antero Midstream Corporation was originally formed as Antero Resources Midstream Management LLC in 2013 to become 
the general partner of Antero Midstream Partners LP (“Antero Midstream Partners”).  On May 4, 2017, Antero Resources Midstream 
Management LLC converted from a limited liability company to a limited partnership under the laws of the State of Delaware and 
changed its name to Antero Midstream GP LP (“AMGP”) in connection with its initial public offering.  On March 12, 2019, pursuant 
to the Simplification Agreement, dated as of October 9, 2018, by and among AMGP, Antero Midstream Partners and certain of their 
affiliates (the “Simplification Agreement”), (i) AMGP was converted from a limited partnership to a corporation under the laws of the 
State of Delaware and changed its name to Antero Midstream Corporation (the “Conversion”), (ii) an indirect, wholly owned 
subsidiary of Antero Midstream Corporation was merged with and into Antero Midstream Partners, with Antero Midstream Partners 
surviving the merger as an indirect, wholly owned subsidiary of Antero Midstream Corporation (the “Merger”) and (iii) Antero 
Midstream Corporation exchanged (the “Series B Exchange” and, together with the Conversion, the Merger and the other transactions 
pursuant to by the Simplification Agreement, the “Transactions”) each issued and outstanding Series B Unit (the “Series B Units”) 
representing a membership interest in Antero IDR Holdings LLC (“IDR Holdings”) for 176.0041 shares of its common stock, par 
value $0.01 per share (“AM common stock”).  As a result of the Transactions, Antero Midstream Partners became and is now a 
wholly owned subsidiary of Antero Midstream Corporation and former shareholders of AMGP, unitholders of Antero Midstream 
Partners, including Antero Resources Corporation (“Antero Resources”), and holders of Series B Units became owners of AM 
common stock.  Unless the context otherwise requires, references to the “Company” refer to (i) for the period prior to March 13, 2019, 
AMGP and its consolidated subsidiaries, which did not include Antero Midstream Partners and its subsidiaries, and (ii) for the period 
beginning on March 13, 2019, Antero Midstream Corporation and its consolidated subsidiaries, including Antero Midstream Partners 
and its subsidiaries, including Antero Midstream LLC, Antero Water LLC (“Antero Water”), Antero Treatment LLC and Antero 
Midstream Finance Corporation (“Finance Corp”).  

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.  The Company, through Antero Midstream Partners and its affiliates, provides midstream services to Antero 
Resources under long-term contracts.   

The Company’s gathering and compression assets comprise 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 fresh 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 treatment assets also include other flowback and produced water 
treatment facilities. 

The Company, through Antero Midstream Partners, also has a 15% equity interest in a gathering system of Stonewall Gas 

Gathering LLC (“Stonewall”) and a 50% equity interest in a joint venture to develop processing and fractionation assets with 
MarkWest Energy Partners, L.P. (“MarkWest”), a wholly owned subsidiary of MPLX, LP (“MPLX”) (the “Joint Venture”).  See 
Note 16—Investments in Unconsolidated Affiliates.  

The Company’s corporate headquarters are located in Denver, Colorado. 

(2)  Summary of Significant Accounting Policies 

(a)  Basis of Presentation 

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally 

accepted in the United States (“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, 2019 and 2020, and the results of the Company’s operations and its cash flows for the years ended December 31, 
2018, 2019 and 2020.  The Company has no items of other comprehensive income (loss); therefore, net income (loss) is equal to 
comprehensive income (loss).

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

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 6—Transactions with Affiliates). 

(b)  Principles of Consolidation 

The accompanying consolidated financial statements include (i) for the period prior to March 13, 2019, the accounts of 

AMGP and its consolidated subsidiaries, which did not include Antero Midstream Partners and its subsidiaries, and (ii) for the period 
beginning on March 13, 2019, the accounts of Antero Midstream Corporation and its consolidated subsidiaries, including Antero 
Midstream Partners and its subsidiaries, which were acquired in the Transactions.  See Note 3—Business Combination.  All 
significant intercompany accounts and transactions have been eliminated in the Company’s consolidated financial statements. 

Prior to the Transactions on March 12, 2019, AMGP had determined that Antero Midstream Partners was a variable interest 

entity (“VIE”) for which AMGP was not the primary beneficiary and therefore did not consolidate.  AMGP concluded that Antero 
Resources was the primary beneficiary of Antero Midstream Partners and Antero Resources consolidated its financial results.  Antero 
Resources was the primary beneficiary based on its power to direct the activities that most significantly impacted Antero Midstream 
Partners’ economic performance and its obligations to absorb losses or receive benefits of Antero Midstream Partners that would be 
significant to Antero Midstream Partners.  Antero Resources owned approximately 53% of the outstanding limited partner interests in 
Antero Midstream Partners prior to the Transactions and its officers and management group also acted as management of Antero 
Midstream Partners.  AMGP did not own any limited partnership interests in Antero Midstream Partners and had no capital interests in 
Antero Midstream Partners.  AMGP did not provide financial support to Antero Midstream Partners. 

AMGP’s ownership of the non-economic general partner interest in Antero Midstream Partners prior to the Transactions 

provided AMGP with significant influence over Antero Midstream Partners, but not control over the decisions that most significantly 
impacted the economic performance of Antero Midstream Partners.  AMGP’s indirect ownership of the IDRs of Antero Midstream 
Partners prior to the Transactions entitled AMGP to receive cash distributions from Antero Midstream Partners when distributions 
exceeded certain target amounts.  AMGP’s ownership of these interests prior to the Transactions did not require AMGP to provide 
financial support to Antero Midstream Partners.  AMGP obtained these interests upon its formation for no consideration.  Therefore, 
AMGP had no cost basis and classified its investment in Antero Midstream Partners as a long term investment.  Prior to the 
Transactions, AMGP’s share of Antero Midstream Partner’s earnings were a result of AMGP’s ownership of the IDRs was accounted 
for using the equity method of accounting.  AMGP recognized distributions earned from Antero Midstream Partners as “Equity in 
earnings of unconsolidated affiliates” on its statement of operations in the period in which they were earned and were allocated to 
AMGP’s capital account.  AMGP’s long-term interest in the IDRs on the balance sheet was recorded in “Investment in unconsolidated 
affiliates.”  The ownership of the general partner interests and IDRs did not provide AMGP with any claim to the assets of Antero 
Midstream Partners other than the balance in its Antero Midstream Partners capital account.  Income related to the IDRs was 
recognized as earned and increased AMGP’s capital account and equity investment.  When these distributions were paid to AMGP, 
they reduced its capital account and its equity investment in Antero Midstream Partners.   

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 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 

F-10

Notes to Consolidated Financial Statements (Continued) 

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. 

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)  Revenue Recognition 

The Company, through Antero Midstream Partners and its affiliates, 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 wastewater treatment services performed by the Company 
prior to idling of the Clearwater Facility (as defined below) in September 2019, the quantities of wastewater treated for its customers, 
(iv) in the case of wastewater services provided by third parties, the third-party costs the Company incurs plus 3% or (v) in the case of 
flowback and produced water treatment 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 7—Revenue.   

(d)  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, the valuation of assets and liabilities acquired 
from Antero Midstream Partners, as well as the valuation of accrued liabilities, among others.  Although management believes these 
estimates are reasonable, actual results could differ from these estimates. 

(e)  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.   

(f)  Property and Equipment 

Property and equipment primarily consists of gathering pipelines, compressor stations and the wastewater treatment facility 

and related landfill (collectively, the “Clearwater Facility”) previously used for the disposal of salt therefrom, other flowback and 
produced water treatment facilities; and 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.   

Amortization of landfill airspace consists of the amortization of landfill capital costs, including those that have been incurred 

and capitalized and estimated future costs for landfill development and construction, and the amortization of asset retirement costs 
arising from landfill final capping, closure and post-closure obligations.  Amortization expense is recorded on a units-of-consumption 

F-11 

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

basis, applying cost as a rate per-cubic yard.  The rate per-cubic yard is calculated by dividing each component of the amortizable 
basis of the landfill by the number of cubic yards needed to fill the corresponding asset’s airspace.  Landfill capital costs and closure 
and post-closure asset retirement costs are generally incurred to support the operation of the landfill over its entire operating life and 
are, therefore, amortized on a per-cubic yard basis using a landfill’s total airspace capacity.  Estimates of disposal capacity and future 
development costs are created using input from independent engineers and internal technical teams and are reviewed at least annually.  

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.  The Company recognized an 
impairment with respect to the Clearwater Facility during the year ended December 31, 2019.  See Note 4—Clearwater Facility Idling. 
The Company recognized a $90 million impairment with respect to the freshwater delivery system during the year ended December 
31, 2020. 

(g)  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. 

Asset retirement obligations are recorded for fresh water impoundments and waste water pits when an abandonment date is 

identified.  The Company records the fair value of its freshwater impoundment and waste water 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.  Fresh 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.  As of December 31, 2020, the 
Company has $5 million of asset retirement obligations it expects to settle within the next 12 months that are recorded in Other current 
liabilities on the consolidated balance sheet. 

The Company 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.  See Note 4—Clearwater Facility Idling.  

(h)  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. 

F-12 

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

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, 2019 and 2020, the Company had not recorded any liabilities for litigation, environmental or other 

contingencies. 

(i)  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 the Transactions, as well as costs allocated by Antero Resources for grants made prior to the 
Transactions.  Costs allocated from Antero Resources are offset to additional paid in capital on the consolidated balance sheet.  See 
Note 6—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 12—Equity-Based Compensation. 

(j)  Income Taxes 

The Company recognizes deferred 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 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 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. 

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted.  The CARES Act 

allows corporations with net operating losses (“NOLs”) incurred in 2018, 2019 and 2020 to carry back such NOLs to each of the five 
years preceding the year of the NOLs, beginning with the earliest year in which there was taxable income, and claim an income tax 
refund in the applicable carryback years.  As a result of this NOLs carryback provision in the CARES Act, the Company was able to 
recognize an income tax refund receivable in March 2020 of $55 million, including $11 million in income tax benefit for the current 
year and $44 million of previously recognized deferred income tax benefit.  As of December 31, 2020, the Company had received $39 
million of this refund. 

(k)  Fair Value Measures 

The Financial Accounting Standards Board (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 

F-13 

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

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 sheet 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.  The assets and 
liabilities of Antero Midstream Partners were recorded at fair value as of the acquisition date, March 12, 2019 (see Note 3—Business 
Combination).  Additionally, the Company uses certain valuation techniques in performing its annual goodwill impairment test 
described below and in determining the fair value of property and equipment, both of which were subject to impairment write downs 
during the years ended December 31, 2019 and 2020.  

(l)  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 16—Investments in Unconsolidated Affiliates. 

(m)  Business Combinations 

The Company recognizes and measures the assets acquired and liabilities assumed in a business combination based on their 

estimated fair values at the acquisition date, with any remaining difference recorded as goodwill.  For acquisitions, management 
engages an independent valuation specialist, as applicable, to assist with the determination of fair value of the assets acquired, 
liabilities assumed and goodwill, based on recognized business valuation methodologies.  If the initial accounting for the business 
combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be 
recorded.  Subsequent to the acquisition, and not later than one year from the acquisition date, the Company will record any material 
adjustments to the initial estimate based on new information obtained that would have existed as of the acquisition date.  An 
adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period of the 
adjustment.  Acquisition-related costs are expensed as incurred in connection with each business combination.  See Note 3—Business 
Combination. 

(n)  Goodwill and Intangible Assets 

Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in the acquisition 
of a business.  Goodwill is not amortized, but rather is tested for impairment annually in the fourth quarter and when events or changes 
in circumstances indicate that the fair value of a reporting unit with goodwill has been reduced below its carrying value.  The 
impairment test requires allocating goodwill and other assets and liabilities to reporting units.  The fair value of each reporting unit is 
determined and compared to the carrying value of the reporting unit.  The fair value is 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.  If the fair value of the reporting unit is less than the carrying value, including 
goodwill, the excess of the book value over the fair value of goodwill is charged to net income as an impairment expense.   

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.  As of 
March 31, 2020, the Company’s goodwill was fully impaired.  See Note 4—Clearwater Facility Idling and Note 5—Goodwill and 
Intangibles. 

(o)  Treasury Share Retirement 

The Company periodically retires treasury shares acquired through share repurchases and returns those shares to the status of 

F-14 

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

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

(3)  Business Combination 

On March 12, 2019, AMGP and Antero Midstream Partners completed the Transactions.  The Transactions have been 

accounted for using the acquisition method of accounting with Antero Midstream Corporation identified as the acquirer of Antero 
Midstream Partners.

All customer relationships are subject to amortization, which is recognized over a weighted-average period of 23 years for the 

remaining economic life of the relationship as of the acquisition date.  

The purchase price allocation resulted in the recognition of $575 million of goodwill in three reporting units within the 

Company’s gathering and processing segment and $340 million of goodwill in two reporting units within its water handling segment.  
Substantially all of the goodwill is expected to be deductible for tax purposes.  Goodwill represented the efficiencies realized with 
simplifying the Company’s corporate structure to own, operate and develop midstream energy infrastructure primarily to service 
Antero Resources. See Note 5—Goodwill and Intangibles.

Notes to Consolidated Financial Statements (Continued) 

The Company’s financial statements include $6 million of acquisition-related costs associated with the Transactions for the 

year ended December 31, 2019.  These costs were expensed as general and administrative costs. 

(4)  Clearwater Facility Idling 

On September 18, 2019, the Company commenced a strategic evaluation of the Clearwater Facility at which time, such 

facility was idled.  The Company expects the facility to be idled for the foreseeable future.  Accordingly, the Company performed an 
impairment analysis of the facility and determined: (i) to reduce the carrying value of the facility to its estimated salvage value, which 
included the land associated with the Clearwater Facility; (ii) the fair value of the goodwill assigned to the wastewater treatment 
reporting unit was less than its carrying value resulting in an impairment charge to goodwill; and (iii) the customer relationships 
intangible asset was impaired.  Additionally, during the year ended December 31, 2020, the Company determined that the carrying 
value of the landfill was no longer recoverable resulting in an impairment charge to property and equipment. The following table 
shows the impairment charges for the years ended December 31, 2019 and 2020 related to the Clearwater Facility, which also reflect 
the final purchase price allocation of the Transactions (in thousands):

The Company incurred $11 million and $15 million in facility idling costs for the care and maintenance of the Clearwater 

Facility during the years ended December 31, 2019 and 2020, respectively. 

(5)  Goodwill and Intangibles  

The Company evaluates goodwill for impairment annually during the fourth quarter and whenever events or changes in 

circumstances indicate it is more likely than not that the fair value of a reporting unit with goodwill is less than its carrying amount.  
Significant assumptions used to estimate the reporting units’ fair value include the discount rate as well as estimates of future cash 
flows, which are impacted primarily by commodity prices and producer customers’ development plans (which impact volumes and 
capital requirements). 

During the third quarter of 2019, the Company incurred impairment charges to the goodwill and customer relationships 

intangible asset associated with the Clearwater Facility, which is in the water handling segment.  See Note 4—Clearwater Facility 
Idling. 

During the fourth quarter of 2019, the Company incurred impairment charges of $298 million to its fresh water delivery and 

services reporting unit, which is in the water handling segment.  This was primarily due to decreased water volumes driven by 
decreased drilling operations by Antero Resources. There was no goodwill remaining in this segment after this impairment was 
incurred. 

During the first quarter of 2020, the Company performed an interim impairment analysis of the goodwill due to changes in 

Antero Resources’ drilling plans as a result of the decline in commodity prices.  As a result of this evaluation, the Company impaired 
all remaining goodwill of $575 million associated with its gathering and processing segment in the first quarter of 2020.  

All customer relationships are subject to amortization and will be amortized over a weighted-average period of 21 years, 
which reflects the remaining economic life of the relationships as of December 31, 2020.  The changes in the carrying amount of 
customer relationships for the years ended December 31, 2019 and 2020 were as follows (in thousands):

Substantially all revenues earned in the years ended December 31, 2019 and 2020 were earned from Antero Resources, under 

various agreements for gathering and compression and water handling services.  Revenues earned from gathering and processing 
services consists of lease income.  There were no such revenues earned by AMGP for the year ended December 31, 2018. 

(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 $6 million and $7 million during the years ended 
December 31, 2019 and 2020, 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.  There were no such charges to AMGP during the year 
ended December 31, 2018.  For the years ended December 31, 2018, 2019 and 2020, general and administrative expenses charged to 
the Company by Antero Resources were $0.5 million, $33 million and $25 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 (i) 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, and (ii) an annual management service fee.  The Company reimburses Antero Resources directly for all general and 
administrative costs charged to it. See Note 12—Equity-Based Compensation.

satisfies a performance obligation by delivering a service to a customer.  The Company currently derives substantially all of its 
revenues from Antero Resources.  The following sets forth the nature, timing of satisfaction of performance obligations and significant 
payment terms of the Company’s contracts with Antero Resources. 

Gathering and Compression Agreement 

Pursuant to the gathering and compression agreement with Antero Resources, 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 
except for acreage subject to third-party commitments or pre-existing dedications.  The Company also has an option to gather and 
compress natural gas produced by Antero Resources on any additional acreage it acquires during the term of the agreement outside of 
West Virginia, Ohio and Pennsylvania on the same terms and conditions.  In December 2019, the Company and Antero Resources 
agreed to extend the initial term of the gathering and compression agreement to 2038 and established a growth incentive fee program 
whereby low pressure gathering fees will be reduced from 2020 through 2023 to the extent Antero Resources achieves certain 
volumetric targets at certain points during such time.  For the year ended December 31, 2020, the company provided Antero 
Resources $48 million in rebates.  Upon completion of the initial contract term, the 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. 

  Under the gathering and compression agreement, the Company receives a low pressure gathering fee, a high pressure 

gathering fee and a compression fee, in each case subject to CPI-based adjustments.  In addition, the agreement stipulates that the 
Company receives a reimbursement for the actual cost of electricity used at its compressor stations. 

  The Company determined that the gathering and compression agreement is an operating lease as Antero Resources obtains 

substantially all of the economic benefit of the asset and has the right to direct the use of the asset.  The gathering system is an 
identifiable asset within the gathering and compression agreement, and it consists of underground low pressure pipelines that generally 
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 or plant.  The gathering system is considered a single lease due to the 
interrelated network of the assets.  When a modification to the gathering and compression agreement occurs, the Company reassesses 
the classification of this 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 system, which are performed on time-elapsed measures.  All lease payments under the future Minimum Volume 
Commitments discussed below are considered to be in-substance fixed lease payments under the gathering and compression 
agreement. 

The Company recognizes revenue 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.  The 
Company invoices the customer the month after each service is performed, and payment is due in the same month.  

Water Services Agreement 

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.  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 per barrel for fresh water deliveries by pipeline directly to the well site.  Additionally, the Company receives a fixed fee per 
barrel for fresh water delivered by truck to high-rate transfer facilities.  For flowback and produced water blending services, the 
Company receives a cost of service fee based on the costs incurred by the Company.  Antero Resources also agreed to pay the 
Company a fixed fee per barrel for wastewater treatment at the Clearwater Facility, which was idled in the third quarter of 2019.  All 
such fees under the agreement are subject to annual CPI-based adjustments and additional fees based on certain costs.   

Under the water services agreement, the Company may also contract with third parties to provide water services to Antero 

Resources.  Antero Resources reimburses the Company for third-party out-of-pocket costs plus a 3% markup. 

F-18 

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

The Company satisfies its performance obligations and recognizes revenue when the fresh water volumes have been 
delivered to the hydration unit of a specified well pad, flowback and produced water blending services have been completed, or prior 
to the idling of the Clearwater Facility in September 2019, when the wastewater volumes were delivered to the Clearwater Facility.  
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. 

Minimum Volume Commitments 

The gathering and compression agreement includes certain minimum volume commitment provisions.  If and to the extent 

Antero Resources requests that the Company construct new high pressure lines and compressor stations, the gathering and 
compression agreement contains minimum volume commitments that require Antero Resources to utilize or pay for 75% of the 
gathering capacity and 70% of the compression capacity of such new construction for 10 years.  The Company recognizes lease 
income from its minimum volume commitments under its gathering and compression agreement on a straight-line basis and additional 
operating lease income is earned when excess volumes are delivered under the contract.  The Company is not party to any leases that 
have not commenced.  Minimum volume commitments for fresh water deliveries under the water services agreement concluded at 
December 31, 2019.   

  Minimum revenue amounts under the gathering and compression minimum volume commitments as of December 31, 2020 are as 
follows (in thousands):

(2)  Fair value of customer contracts acquired as part of the Transactions discussed in Note 3—Business Combination. 

(c)  Transaction Price Allocated to Remaining Performance Obligations 

The majority of the Company’s service contracts have a term greater than one year.  As such, 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 the Company’s service contracts, 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 remainder of the Company’s service contracts, which relate to contracts with third parties, 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. 

(d)  Contract Balances 

Under the Company’s service contracts, the Company invoices customers after its performance obligations have been 
satisfied, at which point payment is unconditional.  Accordingly, the Company’s service contracts do not give rise to contract assets or 
liabilities.  As of December 31, 2020, the Company’s receivables with customers were $101 million and $74 million, respectively.

Investment in Antero Midstream Partners includes $2 million of transaction costs associated with the Transactions.  See Note 3—Business Combination. 

As of December 31, 2019 and 2020, the Company has a deferred tax asset in its Investment in Antero Midstream Partners of 

$31 million and $38 million, respectively.  At the time of the Transactions on March 12, 2019, the investment in Antero Midstream 
Partners was recorded at fair value for both GAAP and income tax purposes.  The GAAP versus tax treatment of activity occurring 
after the transaction, such as the treatment of impairments and differing recovery rates of the underlying assets, gave rise to the 
deferred tax asset.  Due to Antero Midstream Partners’ strong history of pre-tax earnings, the Company believes the benefits of this 
deferred tax asset will be realized.   

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

deferred tax assets will be realized based on a more-likely-than-not standard of judgment.  The ultimate realization of deferred 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 tax assets are deductible, management 
believes that the Company will realize the benefits of these deductible differences and thus has not recorded a valuation allowance. 

As of December 31, 2020, the Company has U.S. federal and state NOL carryforwards before the effect of income taxes of 

$211 million and $315 million, respectively, which have no expiration date.  Tax years 2017 through 2020 remain open to 
examination by the U.S. Internal Revenue Service.  The Company and its subsidiaries file tax returns with various state taxing 
authorities and those returns remain open to examination for tax years 2016 through 2020.

(a)  Antero Midstream Partners Revolving Credit Facility 

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

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

“Borrower”), has a senior secured revolving credit facility (the “Credit Facility”) with a consortium of banks.  Lender commitments 
under the Credit Facility are currently $2.13 billion.  As of December 31, 2019, the Borrower had outstanding borrowings under the 
Credit Facility of $960 million with a weighted average interest rate of 3.15%.  As of December 31, 2020, the Borrower had 
outstanding borrowings under the Credit Facility of $614 million with a weighted average interest rate of 1.66%.  No letters of credit 
under the Credit Facility were outstanding as of December 31, 2019 and 2020.  The maturity date of the facility is October 26, 2022.  
The Credit Facility includes fall away covenants and lower interest rates that are triggered if and when the Borrower is assigned an 
Investment Grade Rating (as defined in the Credit Facility).  

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 previously adopted by the board of directors of the general partner of the Borrower, 
provided that no event of default exists or would be caused thereby, and only to the extent permitted by the Borrower’s organizational 
documents.  The Borrower was in compliance with all of the financial covenants under the Credit Facility as of December 31, 2019 
and 2020. 

Principal amounts borrowed are payable on the maturity date with such borrowings bearing interest that is payable quarterly 
or, in the case of Eurodollar Rate Loans, at the end of the applicable interest period if shorter than six months.  Interest is 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.  
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. 

(b)   5.375% Senior Notes Due 2024 

On September 13, 2016, Antero Midstream Partners and its wholly owned subsidiary, Finance Corp (together with Antero 

Midstream Partners, 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, the closing date 
of the Transactions, and the related premium of $2.6 million will be amortized into interest expense over the life of the 2024 Notes.  
The 2024 Notes are unsecured and effectively subordinated to the Credit Facility to the extent of the value of the collateral securing 
the Credit Facility.  The 2024 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 2024 Notes is payable on March 15 and September 15 of each year.  Antero Midstream Partners 
may redeem all or part of the 2024 Notes at any time at redemption prices ranging from 102.688% as of December 31, 2020 to 
100.00% on or after September 15, 2022.  If Antero Midstream Partners undergoes a change of control followed by a rating decline, 
the holders of the 2024 Notes will have the right to require Antero Midstream Partners to repurchase all or a portion of the 2024 Notes 
at a price equal to 101% of the principal amount of the 2024 Notes, plus accrued and unpaid interest. 

(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

(f)  Senior Notes Guarantors 

The Company and each of the Company’s wholly owned subsidiaries (except for the Issuers) has fully and unconditionally 

guaranteed the 2024 Notes, 2026 Notes, 2027 Notes and 2028 Notes (collectively the “Senior Notes”).  In the event a guarantor is sold 
or disposed of (whether by merger, consolidation, the sale of a sufficient amount of its capital stock so that it no longer qualifies as a 
Restricted Subsidiary (as defined in the applicable indenture governing the series of Senior Notes) of the Issuer or the sale of all or 
substantially all of its assets) and whether or not the guarantor is the surviving entity in such transaction to a person that is not an 
Issuer or a Restricted Subsidiary of an Issuer, such guarantor will be 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.

The Company’s general and administrative expenses include equity-based compensation costs related to the Antero 

Midstream GP LP Long-Term Incentive Plan (“AMGP LTIP”) and the Series B Units prior to the Transactions.  Equity-based 
compensation after the Transactions include (i) costs allocated to Antero Midstream Corporation by Antero Resources for grants made 
prior to the Transactions pursuant to the Antero Resources Corporation Long-Term Incentive Plan (the “AR LTIP”), (ii) costs related 
to the Antero Midstream Corporation Long-Term Incentive Plan (the “AM LTIP”) and (iii) the Exchanged B Units (as defined below).  
The Company’s portion of the equity-based compensation expense is included in general and administrative expenses, and recorded as 
a credit to the applicable classes of equity.  Equity-based compensation expense allocated to Antero Midstream Partners was $4.9 
million for the period from March 13, 2019 to December 31, 2019 and $5.2 million for the year ended December 31, 2020. For grants 
made prior to the Transactions, Antero Resources has total unamortized expense related to its various equity-based compensation 
plans that can be allocated to the Company of approximately $8 million as of December 31, 2020, which includes grants made under 
the Antero Midstream Partners Long Term Incentive Plan (the “AMP LTIP”) prior to the Transactions, which were converted into 
awards under the AM LTIP.  A portion of this will be allocated to Antero Midstream Partners as it is amortized over the remaining 
service period of the related awards.  The Company does not reimburse Antero Resources for noncash equity compensation allocated 
to it for awards issued under the AR LTIP.   

Exchanged B Units 

As of December 31, 2018, IDR Holdings had 98,600 Series B Units authorized and outstanding that entitled the holders to 

receive up to 6% of the amount of the distributions that Antero Midstream Partners made on its incentive distribution rights (“IDRs”) 
in excess of $7.5 million per quarter, subject to certain vesting conditions.  On December 31, 2018, 65,745 Series B Units were vested.  
The holders of vested Series B Units had the right to convert the units to common shares with a value equal to their pro rata share of 
up to 6% of any increase in AMGP’s equity value in excess of $2.0 billion.    

Upon Closing of the Transactions, each Series B Unit, vested and unvested, was exchanged for 176.0041 shares of our 
common stock (the “Series B Exchange”).  A total of 17,353,999 shares of the Company’s common stock were issued in exchange for 
the 98,600 Series B Units then outstanding (the “Exchanged B Units”), which included 5,782,601 restricted shares of the Company’s 
common stock issued in exchange for the 32,855 unvested Series B Units.   

The Company accounted for the Series B Exchange as a share-based payment modification under FASB ASC Topic 718, 
Stock Compensation.  On March 12, 2019, which is the modification date, the Company determined the estimated fair value of the 
unvested Series B Unit awards using a Monte Carlo simulation using various assumptions including a floor equity value of $2.0 
billion, expected volatility of 40% based on historical volatility of a peer group of publicly traded partnerships, a risk free rate of 
2.51% and expected IDR distributions based on internal estimates discounted based on a weighted average cost of capital assumption 
of 7.25%.  Based on these assumptions, the estimated value of each Series B Unit was $1,257 when exchanged for shares of the

Company’s common stock.  The fair value measurement is based on significant inputs not observable in the market and thus 
represents a Level 3 measurement within the fair value hierarchy.  The unvested Exchanged B Units retained the same vesting 
conditions as the Series B Units and vested on December 31, 2019.  No awards were issued and outstanding as of December 31, 2019 
and 2020. Expenses related to Exchanged B Units were recognized on a straight-line basis over the requisite service period of the 
entire award.  Forfeitures were accounted for as they occur by reversing the expense previously recognized for awards that were 
forfeited during the period. 

The Company recognized $66 million of equity-based compensation expense related to the Series B awards, including the 

Series B Units prior to the Closing of the Transactions and the Exchanged B Units following the Closing of the Transactions, for the 
year ended December 31, 2019.  For the year ended December 31, 2018, the Company recognized $34 million of equity-based 
compensation expense related to the Series B Units.   

AMGP LTIP 

On April 17, 2017, Antero Midstream GP LP adopted the AMGP LTIP pursuant to which certain non-employee directors of 

Antero Midstream GP LP’s general partner and certain officers, employees and consultants of Antero Resources were eligible to 
receive awards representing equity interests in Antero Midstream GP LP.  For the years ended December 31, 2018 and 2019, the 
Company recognized expense of $0.7 million and $0.2 million, respectively, related to these awards.  Expenses related to these awards 
were recognized on a straight-line basis over the requisite service period of the entire award.  Forfeitures were accounted for as they 
occur by reversing the expense previously recognized for awards that were forfeited during the period.  In connection with the 
Transactions, the AMGP LTIP was terminated on March 12, 2019.  No expense was recognized for the year ended December 31, 
2020. 

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 AM 
LTIP provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, 
other stock-based awards, cash awards and substitute awards.  The terms and conditions of the awards granted are established by the 
compensation committee of the Board.  The Company is authorized to grant up to 15,398,901 shares of common stock to employees 
and directors under the AM LTIP.  As of December 31, 2020, a total of 11,131,949 shares were available for future grant under the 
AM LTIP.   For the years ended December 31, 2019 and 2020, the Company recognized expense of $2.7 million and $7.6 million, 
respectively, related to these awards.  Expenses related to restricted stock units (“RSUs”) are 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. 

(b)  Restricted Stock Unit Awards 

As part of the Transactions, each of the unvested outstanding phantom units granted under the AMP LTIP was assumed by 
the Company 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. 

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. 

Summary Information for Restricted Stock Unit Awards

Intrinsic values are based on the closing price of the Company’s common shares on the referenced dates.  As of December 

31, 2020, unamortized expense of $19 million related to the unvested RSUs is expected to be recognized over a weighted average 
period of approximately 2.4 years and the Company’s proportionate share will be allocated to it as it is recognized.   

(c)  Performance Share Unit Awards 

Performance Share Unit Awards Based on Return on Invested Capital (“ROIC”) 

In 2019, the Company granted performance share units (“PSUs”) to certain of its employees and executive officers, a portion 

of which vest based on the Company’s actual ROIC (as defined in the award agreement) over a three-year period as compared to a 
targeted ROIC (“ROIC PSUs”).  The number of shares of common stock that may ultimately be earned with respect to the ROIC 
PSUs ranges from zero to 200% of the target number of ROIC PSUs originally granted.  Expense related to the ROIC PSUs is 
recognized based on the number of shares of 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. 

On December 17, 2019, the compensation committee of the Board modified the terms for the ROIC PSU agreement.  

Accordingly, the Company accounted for the amended agreement as a share-based payment modification under ASC 718, Stock 
Compensation and revalued the awards as of the modification date.  Expense for the awards are recognized on a straight-line basis 
over the requisite service period of the entire award.   

In 2019 and 2020, the likelihood of achieving the performance conditions related to ROIC PSU awards outstanding was 

probable and, therefore, for the years ended December 31, 2019 and 2020, the Company recognized expense of $0.2 million and $0.3 
million, respectively.

over a period of up to three years.  In July 2020, the Company granted additional cash awards of $0.7 million to certain non-executive 
employees under the AM LTIP that vest ratably over a period of four years.  The compensation expense for these awards is recognized 
ratably over the applicable vesting period.  As of December 31, 2020, the Company has accrued $1.8 million in other liabilities in the

(14)  Equity and Earnings Per Common Share 

(a)  Preferred Stock 

The Board authorized 100,000,000 shares of preferred stock in connection with the closing of the Transactions (see Note 3—

Business Combination) on March 12, 2019, and issued 10,000 shares of preferred stock designated as "5.5% Series A Non-Voting 
Perpetual Preferred Stock" (the "Series A Preferred Stock"), to The Antero Foundation on that date.  Dividends on the Series A 
Preferred Stock are cumulative from the date of original issue and payable in cash on the 45th day following the end of each fiscal 
quarter, or such other dates as the Board will approve, at a rate of 5.5% per annum on (i) the liquidation preference per share of 
Series A Preferred Stock (as described below) and (ii) the amount of accrued and unpaid dividends for any prior dividend period on 
such share of Series A Preferred Stock, if any.  At any time following the date of issue, in the event of a change of control, or at any 
time on or after March 12, 2029, the Company may redeem the Series A Preferred Stock at a price equal to $1,000 per share, plus any 
accrued and unpaid dividends, payable in cash; provided that if any shares of the Series A Preferred Stock are held by The Antero 
Foundation at the time of such redemption, the price for redemption of each share of Series A Preferred Stock will be the greater of (i) 
$1,000 per share, plus any accrued but unpaid dividends, and (ii) the fair market value of the Series A Preferred Stock. On or after 
March 12, 2029, the holder of each share of Series A Preferred Stock (other than The Antero Foundation) may convert such shares, at 
any time and from time to time, at the option of the holder into a number of shares of 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 earnings (loss) per common shares, assuming dilution because the inclusion 

of these awards would have been anti-dilutive. 

(c)  Earnings Per Common Share 

Earnings per common share—basic for (i) the year ended December 31, 2018 is computed by dividing net income 

attributable to AMGP by the basic weighted average number of common shares representing limited partner interest in AMGP 
outstanding during the period and (ii) the years ended December 31, 2019 and 2020 is computed by dividing net income (loss) 
attributable to Antero Midstream Corporation by the basic weighted average number of shares of AM common stock outstanding 
during the period.  Earnings per common share—assuming dilution 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 shares outstanding are equal to basic weighted average shares outstanding because the 
effect of all equity awards is anti-dilutive.

As the Transactions were accounted for under the acquisition method of accounting, the Company estimated the fair value of 
assets acquired and liabilities assumed at March 12, 2019.  See Note 3—Business Combination.  In connection with the Transactions, 
the Company, among other things, issued shares of common stock valued at the closing market price of the common shares at the 
effective time of the Transactions, which was a Level 1 measurement.  

The Company used the discounted cash flow approach, which is an income statement technique, to estimate the fair value of 
the customer relationships and investments in unconsolidated affiliates using a weighted-average cost of capital of 14.1% as of March 
12, 2019, which is based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair 
value hierarchy.  The Company also used this approach in combination with the cost approach to estimate the fair value of property 
and equipment whereby certain property and equipment was adjusted for recent purchases of similar items, economic and functional 
obsolescence, location, normal useful lives and capacity (if applicable).  To estimate the fair value of the long-term debt, the Company 
used Level 2 market data inputs.  

Goodwill 

The Company estimated the fair value of its assets in performing its goodwill impairment analysis.  The Company utilized a 

combination of approaches to discounted cash flow approach, comparable company method and the market value approach.  The 
Company used a weighted-average cost of capital of 10.0% and 18.0% as of December 31, 2019 and March 31, 2020, respectively, 
which were based on significant inputs not observable in the market, and thus represents a Level 3 measurement within the fair value 
hierarchy. 

Property and equipment 

The Company estimated the undiscounted future cash flow projections to assess its property and equipment for impairment. 

The carrying values of certain fresh water permanent buried pipelines and equipment and fresh water surface pipelines and equipment 
were deemed not recoverable. As a result, the carrying values have been reduced to the estimated fair values, which are based on 
discounted future cash flows using assumptions as to revenues, costs and a discount rate typical of third-party market participants of 
19.0% as of March 31, 2020, which is a Level 3 fair value measurement within the fair value hierarchy. 

Contingent Acquisition Consideration 

In connection with Antero Resources’ contribution of Antero Water and certain water handling assets to Antero Midstream 

Partners in September 2015 (the “Water Acquisition”), Antero Midstream Partners agreed to pay Antero Resources (a) $125 million in 
cash if Antero Midstream Partners delivered 176,295,000 barrels or more of fresh water during the period between January 1, 2017 
and December 31, 2019 and (b) an additional $125 million in cash if Antero Midstream Partners delivered 219,200,000 barrels or 
more of fresh water during the period between January 1, 2018 and December 31, 2020.  This contingent consideration liability is 
valued based on Level 3 inputs related to expected average volumes and weighted average cost of capital.

(16)  Investments in Unconsolidated Affiliates 

(a)  Summary of Investments in Unconsolidated Affiliates 

Investment in Antero Midstream Partners  

Prior to the closing of the Transactions, AMGP did not consolidate Antero Midstream Partners, and AMGP’s share of Antero 
Midstream Partners’ earnings as a result of AMGP’s ownership of the IDRs was accounted for using the equity method of accounting.  
AMGP recognized distributions earned from Antero Midstream Partners as “Equity in earnings of unconsolidated affiliates” on its 
statement of operations in the period in which they were earned and were allocated to AMGP’s capital account.  AMGP’s long-term 
interest in the IDRs on the balance sheet was recorded in “Investment in unconsolidated affiliates.”  The ownership of the general 
partner interests and IDRs did not provide AMGP with any claim to the assets of AMGP other than the balance in its Antero 
Midstream Partners capital account.  Income related to the IDRs was recognized as earned and increased AMGP’s capital account and 
equity investment.  When these distributions were paid to AMGP, they reduced its capital account and its equity investment in Antero 
Midstream Partners.  As a result of the Transactions, Antero Midstream Corporation assumed financial control of Antero Midstream 
Partners and Antero Midstream Partners is now consolidated (see Note 3—Business Combination).  

Investment in Stonewall and MarkWest Joint Venture 

The Company 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 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’s net income (loss) 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

ANTERO MIDSTREAM CORPORATION 

Notes to Consolidated Financial Statements (Continued) 

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 approach under 
FASB ASC Topic 230, Statement of Cash Flows. The Company uses the equity method of accounting to account for its investments in 
Stonewall and the Joint Venture 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 Stonewall and the Joint Venture.

Prior to the closing of the Transactions, AMGP had no reporting segment results.  Following the completion of the 
Transactions, the Company’s operations, which are located in the United States, are organized into two reporting segments: 
(i) gathering and processing and (ii) water handling. 

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 fresh water from sources including 
the Ohio River, local reservoirs and several regional waterways.  The water handling segment also includes the Clearwater Facility 
that was placed in service in 2018 and idled in September 2019 (See Note 4—Clearwater Facility Idling), as well as other fluid 
handling services, which includes high rate transfer, wastewater transportation, disposal and treatment.  See Note 8—Property and 
Equipment. 

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.

FORWARD-LOOKING STATEMENTS
The 2020 Annual Report includes “ forward-looking statements.” Such forward-looking statements are subject to a number of risks and uncertainties, many of which  
are not under Antero Midstream Corporation’s (“Antero Midstream”) control. All statements, except for statements of historical fact, made herein regarding activities,  
events or developments Antero Midstream expects, believes or anticipates will or may occur in the future, such as those regarding Antero Midstream’s cash flow coverage  
expectations, growth opportunities, 2021 and long-term financial and operational outlooks for Antero Midstream and Antero Resources Corporation (“Antero Resources”),  
future plans and future business lines for processing plants and fractionators, Antero Resources’ estimated production, Antero Resources’ expected future  growth and 
Antero Resources’ ability to meet its drilling and development plan, are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and  
Section 21E of the Securities Exchange Act of 1934. Although Antero Midstream believes that the plans, intentions and expectations reflected in or suggested by the  
forward-looking statements are reasonable, there is no assurance that these plans, intentions or expectations will be achieved. Therefore, actual outcomes and results  
could materially differ from what is expressed, implied or forecast in such statements. Antero Midstream cautions you that these forward-looking statements are  subject 
to all of the risks and uncertainties incident to Antero Midstream’s business, most of which are difficult to predict and many of which are beyond the Antero Midstream’s  
control. These risks include, but are not limited to, commodity price volatility, inflation, environmental risks, Antero Resources’ drilling and completion and other operating  
risks, regulatory changes, the uncertainty inherent in projecting Antero Resources’ future rates of production, cash flows and access to capital, the timing of development  
expenditures, impacts of world health events, including the COVID-19 pandemic[, potential shut-ins of production by producers due to lack of downstream demand or  
storage capacity] and the other risks described under the heading “Item 1A . Risk Factors” in Antero Midstream’s Annual Report on Form 10-K for the year ended December  
31, 2020. Any forward-looking statement speaks only as of the date on which such statement is made, and Antero Midstream does not undertake any obligation to correct  
or update any forward-looking statement, whether as  a result of new information, future events or otherwise, except as required by applicable law.

For a definition of free cash flow and a reconciliation to its most comparable measure calculated in accordance with GAAP for the year ended December 31, 2020, please  
see “Item 6. Selected Financial Data” in our Annual Report on Form 10-K for the year ended December 31, 2020.
