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



  Table of Contents

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.

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



  Table of Contents

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



  Table of Contents

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.

  Table of Contents

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.

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.

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.


                                       52



  Table of Contents

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.

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



  Table of Contents

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



                                       57

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

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.
