PART I 

Item 1. Business 

We  were  incorporated  in  February 2007  as  a  wholly-owned  subsidiary  of  Universal  Compression  Holdings, Inc.  In 
August 2007, Universal Compression Holdings, Inc. and Hanover Compressor Company merged into our wholly-owned 
subsidiaries  and  we  became  the  parent  entity  of  Universal  Compression  Holdings, Inc.  and  Hanover  Compressor 
Company, named “Exterran Holdings, Inc.” In November 2015, we completed the Spin-off of our international contract 
operations, international aftermarket services and global fabrication business into a standalone public company operating 
as Exterran Corporation, and we were renamed “Archrock, Inc.” 

We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We are the leading 
provider of natural gas compression services to customers in the oil and natural gas industry throughout the U.S. in terms 
of total compression fleet horsepower and a leading supplier of aftermarket services to customers that own compression 
equipment  in  the  U.S.  Our  business  supports  a  must-run  service  that  is  essential  to  the  production,  processing, 
transportation and storage of natural gas. Our geographic diversity, technically experienced personnel and large fleet of 
natural gas compression equipment enable us to provide reliable contract operations services to our customers. 

We operate in two business segments: 

• Contract  Operations. Our  contract  operations  business  is  comprised  of  our  owned  fleet  of  natural  gas 

compression equipment that we use to provide operations services to our customers. 

•(cid:1) Aftermarket  Services. Our  aftermarket  services  business  provides  a  full  range  of  services  to  support  the 
compression  needs  of  our  customers  that  own  compression  equipment  including  operations,  maintenance, 
overhaul and reconfiguration services and sales of parts and components. 

Natural Gas Compression Industry Overview 

Natural gas compression is a mechanical process whereby the pressure of a given volume of natural gas is increased to a 
desired higher pressure for transportation from one point to another. It is essential to the production and transportation of 
natural gas. Compression  is  typically  required  several  times  during the natural  gas production and  transportation  cycle 
including (i) at the wellhead, (ii) throughout gathering and distribution systems, (iii) into and out of processing and storage 
facilities and (iv) along intrastate and interstate pipelines. Our service offerings focus primarily on the following cycle 
stages. 

Wellhead and Gathering Systems. Natural gas compression is used to transport natural gas from the wellhead through the 
gathering  system.  At  some  point  during  the  life  of  natural  gas  wells,  reservoir  pressures  typically  fall  below  the  line 
pressure of the natural gas gathering or pipeline system used to transport the natural gas to market. At that point, natural 
gas no longer naturally flows into the pipeline. Compression equipment is applied in both field and gathering systems to 
boost  the  pressure  levels of  the  natural  gas  flowing  from  the  well, allowing it to  be transported  to  market.  Changes in 
pressure levels in natural gas fields require periodic changes to the size and/or type of on-site compression equipment. 
Compression equipment is also used to increase the efficiency of a low-capacity natural gas field by providing a central 
compression point from which the natural gas can be produced and injected into a pipeline for transmission to facilities 
for further processing. 

Processing Applications. Compressors may be used in combination with natural gas production and processing equipment 
to process natural gas into other marketable energy sources. In addition, compression services are used for compression 
applications  in  refineries  and  petrochemical plants.  Processing applications  typically  utilize  multiple large  horsepower 
compressors. 

Gas Lift Applications. Compression is used to reinject natural gas into producing oil wells to maintain reservoir pressure 
and  help  lift  liquids  to  the  surface,  which  is  known  as  enhanced  oil  recovery  or  natural  gas  lift  operations.  These 
applications  utilize  low-  to  mid-range  horsepower  compression  equipment  located  at  or  near  the  wellhead  or  large 
horsepower compression equipment of over 1,000 horsepower for a centralized gas lift system servicing multiple wells.

Table of Contents

Many  natural  gas  and  crude  oil producers,  transporters and processors  outsource their compression  services due to  the 
benefits and flexibility of contract compression. Changing well and pipeline pressures and conditions over the life of a 
well  often  require  producers  to  reconfigure  or  replace  their  compression  packages  to  optimize  the  well  production  or 
gathering system efficiency. 

We believe outsourcing compression operations to compression service providers such as us offers customers: 

•(cid:1)

•(cid:1)

•(cid:1)

•(cid:1)

the ability to efficiently meet their changing compression needs over time while limiting the underutilization of 
their owned compression equipment; 
access to the compression service provider’s specialized personnel and technical skills, including engineers and 
field service and maintenance employees, which we believe generally leads to improved production rates and/or 
increased throughput; 
the ability to increase their profitability by transporting or producing a higher volume of natural gas and crude oil 
through decreased compression downtime and reduced operating, maintenance and equipment costs by allowing 
the compression service provider to efficiently manage their compression needs; and
the flexibility to deploy their capital on projects more directly related to their primary business by reducing their 
compression equipment and maintenance capital requirements. 

We believe the U.S. natural gas compression services industry continues to have growth potential over time due to, among 
other things, increased natural gas production in the U.S. from unconventional sources, the aging of producing natural gas 
fields that will require more compression to continue producing the same volume of natural gas and expected increased 
demand for natural gas in the U.S. for power generation, industrial uses and exports, including liquified natural gas exports 
and exports of natural gas via pipeline to Mexico.

Contract Operations Overview 

Compression Services 

We provide comprehensive contract operations services including the personnel, equipment, tools, materials and supplies 
to meet our customers’ natural gas compression needs. Based on the operating specifications at the customer location and 
each  customer’s  unique  needs,  these  services  include  designing,  sourcing,  owning,  installing,  operating,  servicing, 
repairing and maintaining the equipment. We work closely with our customers’ field service personnel so that compression 
services can be adjusted to efficiently match changing characteristics of the reservoir and the natural gas produced and 
may repackage or reconfigure our existing fleet to adapt to our customers’ compression needs. 

During the years ended December 31, 2020, 2019 and 2018, we generated 84%, 80% and 74%, respectively, of our total 
revenue from contract operations.

Our fleet of compressors that we own and use to provide contract operations services consists primarily of reciprocating 
compressors driven by natural gas-powered engines. We continuously work to standardize our compression fleet around 
major components and key suppliers. The standardization of our fleet enables us to minimize our fleet operating costs and 
maintenance  capital  requirements,  reduces  inventory  costs,  facilitates  low-cost  compressor  resizing  and  allows  us  to 
develop improved technical proficiency in our maintenance and overhaul operations, which enables us to achieve higher 
uptime while maintaining lower operating costs.  

Our compressors are predominantly large horsepower, which we define as greater than 1,000 horsepower per unit. We are 
in the process of a multi-year project to install telematic devices on our compressors that will enable us to monitor our 
units remotely. All of our compressors are designed to automatically shut down if operating conditions deviate from a pre-
determined range.

We maintain field service locations from which we service and overhaul our compression fleet. Our equipment undergoes 
routine and preventive maintenance in accordance with our established maintenance schedules, standards and procedures. 
These maintenance practices are updated as technology changes and as our operations group develops new techniques and 
procedures to better service our equipment. Our field technicians are familiar with the condition of our equipment, perform 
the  maintenance  on  the  equipment  and  can  readily  identify  potential  problems.  In  our  experience,  these  maintenance 
practices maximize equipment life and unit availability, minimize avoidable downtime and lower the overall maintenance 
expenditures  over  the  equipment  life.  On  average,  our  compression  packages  undergo  a  major  overhaul  once  every 
nine years depending on the type, size and utilization of the compressor.  

The following table summarizes the size of our natural gas compression fleet as of December 31, 2020:

General Terms of our Contract Operations Service Agreements 

We typically enter into a master service agreement with each customer that sets forth the general terms and conditions of 
our services, and then enter into a separate supplemental service agreement for each distinct site at which we will provide 
contract operations services. The following describes select material terms common to our standard contract operations 
service agreements. 

Term and Termination. Our customers typically contract for our contract operations services on a site-by-site basis that is 
generally reduced if we fail to operate in accordance with the contract requirements. Following the initial minimum term, 
which generally ranges from 12 to 48 months, contract operations services generally continue on a month-to-month basis 
until terminated by either party with 30 days’ advance notice. 

Fees and Expenses. Our customers pay a fixed monthly fee for our contract operations services, which generally is based 
on expected natural gas volumes and pressures associated with a specific application. Our customers generally are required 
to pay our monthly fee even during periods of limited or disrupted natural gas flows, which enhances the stability and 
predictability of our cash flows. We are typically responsible for the costs and expenses associated with our compression 
equipment used to provide the contract operations services except for fuel gas, which is provided by our customers. 

Service Standards and Specifications. We provide contract operations services according to the particular specifications 
of each job, as set forth in the applicable contract. These are typically turn-key service contracts under which we supply 
all services and support and use our compression equipment to provide the contract operations services necessary for a 
particular  application.  In  certain  circumstances,  if  the  availability  of  our  services  does  not  meet  certain percentages 
specified in our contracts, our customers are generally entitled, upon request, to specified credits against our service fees. 

Title and Risk of Loss. We own and retain title to or have an exclusive possessory interest in all compression equipment 
used to provide contract operations services and we generally bear risk of loss for such equipment to the extent the loss is 
not caused by gas conditions, our customers’ acts or omissions or the failure or collapse of the customer’s over-water job 
site upon which we provide the contract operations services.

Insurance. Typically, both we and our customers are required to carry general liability, workers’ compensation, employer’s 
liability, automobile and excess liability insurance. Our insurance coverage includes property damage, general liability 
and commercial automobile liability and other coverage we believe is appropriate. Additionally, we are substantially self-
insured  for  workers’  compensation  and  employee  group  health  claims  in  view  of  the  relatively  high  per-incident 
deductibles we absorb under our insurance arrangements for these risks. We are also self-insured for property damage to 
our offshore assets. 

Aftermarket Services Overview 

Our  aftermarket  services  business  sells  parts  and  components  and  provides  operations,  maintenance,  overhaul  and 
reconfiguration services to customers who own compression equipment. We believe that we are particularly well-qualified 
to  provide  these  services  because  our  highly  experienced  operating  personnel  have  access  to  the  full  range  of  our 
compression services and facilities. In addition, our aftermarket services business provides opportunities to cross-sell our 
contract operations services. During the years ended December 31, 2020, 2019 and 2018, we generated 16%, 20% and 
26%, respectively, of our total revenue from aftermarket services. 

Competitive Strengths 

We believe we have the following key competitive strengths: 

Large horsepower. We have the largest fleet of large horsepower equipment among all outsourced compression service 
providers in the U.S. As of December 31, 2020, 77% of our fleet, as measured by operating horsepower, was comprised 
of  units  that exceed  1,000  horsepower  per  unit.  We  believe  the  trends  driving  demand  for  large  horsepower  units  will 
continue. These trends include (i) high levels of associated gas production from shale wells, which is generally produced 
at a lower initial pressure than dry gas wells, (ii) pad drilling, which brings multiple wells to a single well site with larger 
volumes of gas, (iii) increasing well lateral lengths, which increase natural gas flow through gas gathering systems and 
(iv) high probability drilling programs that allow for efficient infrastructure planning. 

Excellent customer service. We operate in a relationship-driven, service-intensive industry and therefore need to provide 
superior  customer  service.  We  believe  that  our  regionally-based  network,  local  presence,  experience  and  in-depth 
knowledge of our customers’ operating needs and growth plans enable us to respond to our customers’ needs and meet 
their evolving demands on a timely basis. In addition, we focus on achieving a high level of reliability for the services we 
provide in order to maximize uptime and our customers’ production levels. Our sales efforts concentrate on demonstrating 
our commitment to enhancing our customers’ cash flows through superior customer service and after-market support. 

Superior safety performance. We believe our collective safety performance is pivotal to the success of our business and 
is  of primary  importance to  our customers.  We  have a  strong  safety  culture and  a proven  ability to  safely  manage  our 
business  in  a  variety  of  commodity  and  economic  environments.  Our  safety-centric  culture  has  consistently  produced 
industry-leading safety performance for many years, including a 2020 total recordable incident rate of 0.25.  

Large and stable customer base. We have strong relationships with a deep base of midstream companies and natural gas 
and crude oil producers. Our contract operations revenue base is sourced from approximately 525 customers operating 
throughout all major U.S. natural gas and crude oil producing regions. 

Fee-based cash flows. We charge a fixed monthly fee for our contract operations services that our customers are generally 
required to pay regardless of the volume of natural gas we compress in any given month. Our compression packages, on 
average, operate at a customer location for approximately three years. We believe this fee structure and the longevity of 
our operations reduces volatility and enhances the stability and predictability of our cash flows. 

Diversified geographic footprint. We operate in substantially all major natural gas and crude oil producing regions in the 
U.S. Our large fleet and numerous operating locations throughout the U.S., combined with our ability to efficiently move 
equipment among producing regions, mean that we are not dependent on production activity in any particular region. We 
believe our size, geographic scope and broad customer base provide us with improved operating expertise and business 
development opportunities.

Long operating history. We have a long, sustained history of operating in the compression industry and a robust database 
of  fleet  financial  and  operating  metrics  that  provides  an  advantage  compared  to  our  younger  competitors.  We  have 
extensive experience working with our customers to meet their evolving needs. 

Financial resilience and flexibility. We have historically shown and are committed to maintaining capital discipline and 
financial strength, which is critical in a cyclical business such as ours. Maintaining ample liquidity and a prudent balance 
sheet supports our ability to continue to deliver on our long-term strategies and positions us to take advantage of future 
growth opportunities as they arise. 

Business Strategies 

We intend to continue to capitalize on our competitive strengths to meet our customers’ needs through the following key 
strategies: 

Capitalize  on  the  long-term  fundamentals  for  the  U.S.  natural  gas  compression  industry.  We  believe  our  ability  to 
efficiently  meet  our  customers’  evolving  compression  needs,  our  long-standing  customer  relationships  and  our  large 
compression fleet will enable us to capitalize on what we believe are favorable long-term fundamentals for the U.S. natural 
gas  compression  industry.  These  fundamentals  include  significant  natural  gas  resources  in  the  U.S.,  increased 
unconventional natural gas and crude oil production, decreasing natural reservoir pressures and expected increased natural 
gas demand in the U.S. from the growth of liquified natural gas exports, exports of natural gas via pipeline to Mexico, 
power generation and industrial uses. 

Improve profitability. We are focused on increasing productivity and optimizing our processes. Late in 2018 we began a 
process and technology transformation project that will, among other things, upgrade or replace our existing ERP, supply 
chain  and inventory  management  systems  and  expand the  remote  monitoring  capabilities  of  our  compression  fleet.  By 
using technology to make our systems and processes more efficient, we intend to lower our internal costs and improve our 
profitability  over  time.  In  addition,  we  continue  to  focus  on  increasing  the  percentage  of large horsepower equipment 
within  our fleet  in order to capitalize  on  the trends that have  been  driving, and  that  we  believe  will continue  to  drive, 
demand for large horsepower units. 

Optimize our business to generate attractive returns. We plan to continue to invest in strategically growing our business 
both organically and through third-party acquisitions. We see opportunities to grow our contract operations business over 
the long term by putting idle units back to work and adding new horsepower in key growth areas. In addition, because a 
large  amount  of  compression  equipment  is  owned  by  natural  gas  and  crude  oil  producers,  processors,  gatherers, 
transporters and storage providers, we believe there will be additional opportunities for our aftermarket services business 
to provide services and parts to support the operation of this equipment. 

Oil and Natural Gas Industry Cyclicality and Volatility 

Demand for our products and services is correlated to natural gas and crude oil production. Fluctuations in energy prices 
can affect the levels of expenditures by our customers, production volumes and ultimately, demand for our products and 
services;  however,  we  believe  our contract  operations  business  is  typically less  impacted  by  commodity prices  for  the 
following reasons: 

•(cid:1)
•(cid:1)

•(cid:1)

•(cid:1)

fee-based contracts minimize our direct commodity price exposure; 
the natural gas we use as fuel for our compression packages is supplied by our customers, further reducing our 
direct exposure to commodity price risk; 
compression services are a necessary part of midstream energy infrastructure that facilitate the transportation of 
natural gas through gathering systems; 
our  contract  operations  business  is  tied  primarily  to  natural  gas  and  crude  oil  production,  transportation  and 
consumption, which are generally less cyclical in nature than exploration and new well drilling and completion 
activities; 

10 

Table of Contents

•(cid:1)

•(cid:1)

the need for compression services and equipment has grown over time due to the increased production of natural 
gas,  the  natural  pressure  decline  of  natural  gas-producing  basins  and  the  increased percentage  of  natural  gas 
production from unconventional sources; and 
our  compression  packages  operate  at  a  customer  location  for  an  average  of  approximately  three years  during 
which time our customers are generally required to pay a fixed monthly fee regardless of the volume of natural 
gas we compress in any given month. 

Seasonal Fluctuations 

Our  results  of  operations  have  not  historically  reflected  any  material  seasonal  tendencies  and  we  do  not  believe  that 
seasonal fluctuations will have a material impact on us in the foreseeable future.

Market, Suppliers and Customers 

We  conduct  our  contract  operations  activities  in  substantially  all  major  natural  gas  and  crude  oil  producing  areas 
throughout the U.S. and have supply agreements with multiple suppliers to meet our compression equipment needs. 

Our  customer  base  consists  primarily  of  companies  engaged  in  all  aspects  of  the  oil  and  gas  industry  including  large 
integrated and independent natural gas and crude oil producers, processors, gatherers and transporters. 

We have entered into preferred vendor arrangements with some of our customers that give us preferential consideration 
for their compression needs. In exchange, we provide these customers with enhanced product availability, product support 
and favorable pricing. 

During the years ended December 31, 2020, 2019 and 2018, our five most significant customers collectively accounted 
for 28%, 25% and 26%, respectively, of our contract operations and aftermarket services revenue. No single customer 
accounted for 10% or more of our revenue during the years ended December 31, 2020 and 2019. During the year ended 
December 31, 2018, Williams Partners accounted for 11% of our contract operations and aftermarket services revenue. 

Sales and Marketing 

Our marketing and client service functions are coordinated and performed by our sales and field service personnel. Sales 
and field service personnel regularly visit our customers to ensure customer satisfaction, determine customer needs as to 
services  currently  being  provided  and  ascertain  potential  future  compression  services  requirements.  This  ongoing 
communication allows us to respond swiftly to customer requests. 

Competition  

The  natural  gas compression  services  business  is  highly competitive.  Overall,  we  experience considerable competition 
from  companies  that  may  be  able  to  more  quickly  adapt  to  changing  technology within  our  industry  and  changes  in 
economic  conditions  as  a  whole,  more  readily  take  advantage  of  acquisitions  and  other  opportunities  and  adopt  more 
aggressive pricing policies. We believe we are competitive with respect to price, equipment availability, customer service, 
flexibility  in  meeting  customer  needs,  technical  expertise and  quality and  reliability  of  our compression  packages and 
related services. 

Increased size and geographic density offer compression services providers operating and cost advantages. As the number 
of compression locations  and  size  of  the  compression  fleet increases,  the  number  of required  sales,  administrative  and 
maintenance  personnel  increases  at  a  lesser  rate,  resulting  in  operational  efficiencies  and  potential  cost  advantages. 
Additionally,  broad  geographic  scope allows  compression  service providers to  more  efficiently  provide  services  to  all 
customers, particularly those with compression applications in remote locations. We believe our large fleet of compression 
equipment and broad geographic base of operations and related operational personnel give us more flexibility in meeting 
our customers’ needs than many of our competitors.

Governmental Regulation 

Environmental Regulation 

Our  operations  are  subject  to  stringent  and  complex  U.S.  federal,  state  and  local  laws  and  regulations  governing  the 
discharge of materials into the environment or otherwise relating to protection of the environment and to occupational 
safety  and  health.  Compliance  with  these  environmental  laws  and  regulations  may  expose  us  to  significant  costs  and 
liabilities and cause us to incur significant capital expenditures in our operations. Failure to comply with these laws and 
regulations may result in the assessment of administrative, civil and criminal penalties, imposition of investigatory and 
remedial obligations and the issuance of injunctions delaying or prohibiting operations. We believe that our operations are 
in substantial compliance with applicable environmental and safety and health laws and regulations and that continued 
compliance with currently applicable requirements would not have a material adverse effect on us. However, the trend in 
environmental regulation has been to place more restrictions on activities that may affect the environment, and thus, any 
changes in these laws and regulations that result in more stringent and costly waste handling, storage, transport, disposal, 
emission  or  remediation  requirements  could  have  a  material  adverse  effect  on  our  results  of  operations  and  financial 
position. 

The  primary  U.S.  federal  environmental  laws  to  which  our  operations  are  subject  include  the  CAA  and  regulations 
thereunder, which regulate air emissions; the CWA and regulations thereunder, which regulate the discharge of pollutants 
in industrial wastewater and storm water runoff; the RCRA and regulations thereunder, which regulate the management 
and disposal of hazardous and non-hazardous solid wastes; and the CERCLA and regulations thereunder, known more 
commonly  as  “Superfund,”  which  impose  liability  for  the  remediation  of  releases  of  hazardous  substances  in  the 
environment. We are also subject to regulation under the OSHA and regulations thereunder, which regulate the protection 
of the safety and health of workers. Analogous state and local laws and regulations may also apply. 

Air Emissions 

The CAA and analogous state laws and their implementing regulations regulate emissions of air pollutants from various 
sources, including natural gas compressors, and also impose various monitoring and reporting requirements. Such laws 
and regulations may require a facility to obtain pre-approval for the construction or modification of certain projects or 
facilities expected to produce air emissions or result in the increase of existing air emissions, obtain and strictly comply 
with air permits containing various emissions and operational limitations, or utilize specific emission control technologies 
to limit emissions. Our standard contract operations agreement typically provides that the customer will assume permitting 
responsibilities and certain environmental risks related to site operations. 

New Source Performance Standards. On June 3, 2016, the EPA issued final regulations amending the NSPS for the oil 
and  natural  gas  source  category  and  applying  to  sources  of  emissions  of  methane  and  VOC  from  certain  processes, 
activities  and  equipment  that  is  constructed,  modified  or  reconstructed  after  September 18,  2015.  Specifically,  the 
regulation contains both methane and VOC standards for several emission sources not previously covered by the NSPS, 
such as fugitive emissions from compressor stations and pneumatic pumps and methane standards for certain emission 
sources that are already regulated for VOC, such as equipment leaks at natural gas processing plants. The amendments 
also  establish  methane  standards  for  a  subset  of  equipment  that  the  current  NSPS  regulates,  including  reciprocating 
compressors and pneumatic controllers, and extend the current VOC standards to the remaining unregulated equipment. 
On August 13, 2020, the EPA adopted deregulatory amendments to the 2016 rule intended to streamline implementation, 
reduce duplicative  EPA and  state  requirements and  decrease  the burden  of  compliance.  In  particular,  the amendments 
removed the transmission and storage segments from the oil and natural gas source category and rescinded the methane-
specific requirements for production and processing facilities. Several lawsuits were filed challenging these amendments, 
and the U.S. Court of Appeals for the D.C. Circuit ordered an administrative stay of these amendments shortly after they 
were finalized. Although the administrative stay was lifted in October 2020, which brought the amendments into effect, 
the amendments may still be subject to reversal under the new presidential administration. However, on January 20, 2021, 
the  new administration  issued an executive  order calling  on  the  EPA  to, among  other  things,  consider a  proposed  rule 
suspending, revising or rescinding those deregulatory amendments by September 2021. We do not believe that the current 
rules will have a material adverse impact on our business, financial condition, results of operations or cash flows, but we 
cannot yet predict the impact, if any, of any such suspension, revision or rescinding of the current rules.

Venting and Flaring on Federal Lands. On November 18, 2016, the BoLM published final rules to reduce venting and 
flaring  on  federal and  tribal  lands. The rules set  forth  some  novel  requirements  regarding  leak  detection inspections  at 
compressor stations and imposed requirements to reduce emissions from pneumatic controllers and pumps, among other 
things. While the BoLM adopted a rule in 2018 rescinding most of these requirements, that 2018 rule was challenged in 
court and vacated in July 2020. Following that ruling, another court, which had been hearing challenges to the original 
2016 rule, acted on some pending litigation in October 2020 and vacated much of the 2016 rule. 

National Ambient Air Quality Standards. On October 1, 2015, the EPA issued a new NAAQS ozone standard of 70 ppb, 
which is a tightening from the 75 ppb standard set in 2008. This new standard became effective on December 28, 2015, 
and  the  EPA  completed  designating  attainment/non-attainment  regions  under  the  revised  ozone  standard  in  2018.  In 
November 2016, the EPA proposed an implementation rule for the 2015 NAAQS ozone standard, but the agency has yet 
to  issue  a  final  implementation  rule.  State  implementation  of  the  revised  NAAQS  could  result  in  stricter  permitting 
requirements,  delay  or  prohibit  our  customers’  ability  to  obtain  such  permits  and  result  in  increased  expenditures  for 
pollution control equipment, the costs of which could be significant. By law, the EPA must review each NAAQS every 
five years. In December 2018 and again in December 2020, the EPA announced that it was retaining without revision the 
2015 NAAQS ozone standard. However, on January 20, 2021, the new administration issued an executive order calling 
on the EPA to, among other things, propose a Federal Implementation Plan in response to the 2016 NAAQS for California, 
Connecticut, New York, Pennsylvania and Texas by January 2022. We do not believe continued implementation of the 
NAAQS ozone standard will have a material adverse impact on our business, financial condition, results of operations or 
cash flows, but we cannot yet predict the impact, if any, of any new Federal Implementation Plan. 

Texas  Commission  on  Environmental  Quality.  In  January 2011,  the  TCEQ  finalized  revisions  to  certain  air  permit 
programs that significantly increase air emissions-related requirements for new and certain existing oil and gas production 
and gathering sites in the Barnett Shale production area. The final rule established new emissions standards for engines, 
which could impact the operation of specific categories of engines by requiring the use of alternative engines, compressor 
packages or the installation of aftermarket emissions control equipment. The rule became effective for the Barnett Shale 
production  area  in  April 2011,  and  the  lower  emissions  standards  will  become  applicable  between  2020  and  2030 
depending on the type of engine and the permitting requirements. A number of other states where our engines are operated 
have adopted or are considering adopting additional regulations that could impose new air permitting or pollution control 
requirements for engines, some of which could entail material costs to comply. At this time, however, we cannot predict 
whether any such rules would require us to incur material costs. 

General. New environmental regulations and proposals similar to these, when finalized, and any other new regulations 
requiring  the  installation  of  more  sophisticated  pollution  control  equipment  or  the  adoption  of  other  environmental 
protection measures, could have a material adverse impact on our business, financial condition, results of operations and 
cash flows. 

Climate Change Legislation and Regulatory Initiatives 

Congress has previously considered legislation to restrict or regulate emissions of greenhouse gases, such as carbon dioxide 
and  methane.  Energy legislation  and  other initiatives continue  to  be proposed  that  may  be  relevant  to greenhouse  gas 
emissions issues. Almost half of the states, either individually or through multi-state regional initiatives, have begun to 
address  greenhouse  gas  emissions,  primarily  through  the  planned  development  of  emission  inventories  or  regional 
greenhouse gas cap and trade programs. Although most of the state-level initiatives have to date been focused on large 
sources of greenhouse gas emissions, such as electric power plants, it is possible that smaller sources such as our gas-fired 
compressors could become subject to greenhouse gas-related regulation. Depending on the particular program, we could 
be required to control emissions or to purchase and surrender allowances for greenhouse gas emissions resulting from our 
operations. 

Independent of Congress, the EPA has promulgated regulations controlling greenhouse gas emissions under its existing 
CAA  authority. The  EPA  has adopted  rules requiring  many  facilities,  including  petroleum and  natural gas  systems, to 
inventory and report their greenhouse gas emissions. These reporting obligations were triggered for one site we operated 
in 2020. 

13 

Table of Contents

In  addition,  the  EPA  rules provide  air  permitting  requirements  for  certain  large  sources  of  greenhouse  gas  emissions. 
The requirement for large sources of greenhouse gas emissions to obtain and comply with permits will affect some of our 
and our customers’ largest new or modified facilities going forward, but is not expected to cause us to incur material costs. 

At the international level, the U.S. joined the international community at the 21st Conference of the Parties of the United 
Nations Framework Convention on Climate Change in Paris, France, which resulted in an agreement intended to nationally 
determine their contributions and set greenhouse gas emission reduction goals every five years beginning in 2020. While 
the Agreement did not impose direct requirements on emitters, national plans to meet its pledge could have resulted in 
new regulatory requirements. In November 2019, however, plans were formally announced for the U.S. to withdraw from 
the Paris Agreement with an effective exit date in November 2020. On January 20, 2021, the new administration issued 
an executive order commencing the process to reenter the Paris Agreement, although the emissions pledges in connection 
with that effort have not yet been updated. We cannot predict whether re-entry into the Paris Agreement or pledges made 
in connection therewith will result in new regulatory requirements or whether such requirements will cause us to incur 
material costs. 

In  a  separate  executive  order  issued  on  January  20,  2021,  the  new  administration  asked  the  heads  of  all  executive 
departments  and  agencies  to  review  and  take  action  to  address  any  Federal  regulations,  orders,  guidance  documents, 
policies  and  any  similar  agency  actions  promulgated  during  the  prior  administration  that  may  be  inconsistent  with  or 
present  obstacles  to  the  administration’s  stated  goals  of  protecting  public  health  and  the  environment,  and  conserving 
national monuments and refuges. A preliminary list must be provided to the OMB within 30 days of the order. Regulations 
specifically  mentioned  for  review  and  possible  suspension, revision or  rescission  include the  NSPS,  and the  EPA  was 
ordered  to,  among  other  things,  propose  new  regulations  to  establish  comprehensive  standards  for  performance  and 
emission guidelines for methane and VOCs from existing oil and gas operations by September 2021 and propose a Federal 
Implementation Plan in response to the 2016 NAAQS for California, Connecticut, New York, Pennsylvania and Texas by 
January  2022. The  executive  order also  established  an  Interagency Working  Group  on  the  Social  Cost  of  Greenhouse 
Gases, which is called on to, among other things, capture the full costs of greenhouse gas emissions, including the “social 
cost of carbon,” “social cost of nitrous oxide” and “social cost of methane,” which are “the monetized damages associated 
with  incremental  increases  in  greenhouse  gas  emissions,”  including  “changes  in  net  agricultural  productivity,  human 
health, property damage from increased flood risk, and the value of ecosystem services.” Various recommendations from 
the Working Group are due beginning June 1, 2021 and final recommendations no later than January 2022. The executive 
order  also  revoked,  among  other things,  the  March  2019 permit for  the  Keystone  XL  pipeline, ten other  environment-
related executive orders and three Presidential Memoranda of the prior administration. 

Although  it  is  not  currently  possible  to  predict  how  these  executive  orders  or  any  proposed  or  future  greenhouse  gas 
legislation or regulation promulgated by Congress, the states or multi-state regions will impact our business, any regulation 
of  greenhouse  gas  emissions  that  may  be  imposed  in  areas  in  which  we  conduct  business  could  result  in  increased 
compliance costs or additional operating restrictions or reduced demand for our services, and could have a material adverse 
effect on our business, financial condition, results of operations and cash flows. 

Finally, it should be noted that some scientists have concluded that increasing concentrations of greenhouse gases in the 
Earth’s atmosphere can change the climate in a manner that results in significant weather-related effects, such as increased 
frequency and severity of storms, droughts, floods, and other such events. If any of those results occur, it could have an 
adverse effect on our assets and operations and cause us to incur costs in preparing for and responding to them.

Water Discharges 

The CWA and analogous state laws and their implementing regulations impose restrictions and strict controls with respect 
to the discharge of pollutants into state waters or waters of the U.S. The discharge of pollutants into regulated waters is 
prohibited, except in accordance with the terms of a permit issued by the EPA or an analogous state agency. In addition, 
the CWA regulates storm water discharges associated with industrial activities depending on a facility’s primary standard 
industrial classification. Four of our facilities have applied for and obtained industrial wastewater discharge permits and/or 
have sought coverage under local wastewater ordinances. U.S. federal laws also require development and implementation 
of spill prevention, controls and countermeasure plans, including appropriate containment berms and similar structures to 
help prevent the contamination of navigable waters in the event of a petroleum hydrocarbon tank spill, rupture or leak at 
such facilities. 

Waste Management and Disposal

RCRA  and  analogous  state  laws  and  their  implementing  regulations  govern  the  generation,  transportation,  treatment, 
storage and disposal of hazardous and non-hazardous solid wastes. During the course of our operations, we generate wastes 
(including, but not limited to, used oil, antifreeze, used oil filters, sludges, paints, solvents and abrasive blasting materials) 
in quantities regulated under RCRA. The EPA and various state agencies have limited the approved methods of disposal 
for these types of wastes. CERCLA and analogous state laws and their implementing regulations impose strict, and under 
certain conditions, joint and several liability without regard to fault or the legality of the original conduct on classes of 
persons who are considered to be responsible for the release of a hazardous substance into the environment. These persons 
include current and past owners and operators of the facility or disposal site where the release occurred and any company 
that transported,  disposed  of,  or  arranged  for the transport or  disposal  of  the  hazardous  substances  released at the  site. 
Under CERCLA,  such  persons  may  be  subject  to  joint and  several liability  for the  costs  of cleaning  up  the  hazardous 
substances that have been  released into the  environment,  for  damages to  natural  resources  and  for the  costs  of  certain 
health studies. In addition, where contamination may be present, it is not uncommon for neighboring landowners and other 
third  parties  to  file  claims  for  personal  injury,  property  damage  and  recovery  of  response  costs  allegedly  caused  by 
hazardous substances or other pollutants released into the environment. 

We currently own or lease, and in the past have owned or leased, a number of properties that have been used in support of 
our operations for a number of years. Although we have utilized operating and disposal practices that were standard in the 
industry at the time, hydrocarbons, hazardous substances, or other regulated wastes may have been disposed of or released 
on or under the properties owned or leased by us or on or under other locations where such materials have been taken for 
disposal by companies sub-contracted by us. In addition, many of these properties have been previously owned or operated 
by third parties whose treatment and disposal or release of hydrocarbons, hazardous substances or other regulated wastes 
was not under our control. These properties and the materials released or disposed thereon may be subject to CERCLA, 
RCRA  and  analogous  state  laws.  Under  such  laws,  we  could  be  required  to  remove  or  remediate  historical  property 
contamination, or to perform certain operations to prevent future contamination. At certain of such sites, we are currently 
working  with the  prior  owners  who  have  undertaken  to  monitor and clean  up  contamination that  occurred  prior to  our 
acquisition of these sites. We are not currently under any order requiring that we undertake or pay for any cleanup activities. 
However, we cannot provide any assurance that we will not receive any such order in the future. 

Occupational Safety and Health 

We  are  subject  to  the  requirements  of  the  OSHA  and  comparable  state  statutes.  These  laws  and  the  implementing 
regulations  strictly  govern  the  protection  of  the  safety  and  health  of  employees.  The  OSHA’s  hazard  communication 
standard, the EPA’s community right-to-know regulations under Title III of CERCLA and similar state statutes require 
that we organize and/or disclose information about hazardous materials used or produced in our operations.

On January 21, 2021, the new administration issued an executive order on protecting worker health and safety, the stated 
goal of which is to protect the health and safety of workers from COVID-19. In the executive order, Department of Labor 
leaders and, in some cases, the leaders of other Federal Departments are called on to, among other things, issue revised 
guidance to employers on workplace safety during the pandemic, consider whether emergency temporary standards (e.g., 
mask in the workplace) are necessary, review OSHA enforcement efforts related to COVID-19, focus those enforcement 
efforts on violations that put the largest number of workers at serious risk or are contrary to anti-retaliation principles and 
coordinate with State and local government entities responsible for public employee safety. 

While we have robust measures in place that meet or exceed current and recently proposed applicable requirements, and 
while we believe that the executive order will not affect how we are currently managing our business during the COVID-
19 pandemic, at this time we do not know exactly how, or even if, these initiatives will affect our operations. 

Human Capital 

As of December 31, 2020, we had approximately 1,250 employees and had a presence in 39 states. None of our employees 
are subject to a collective bargaining agreement.  

We consider our employees to be our greatest asset and believe that our success depends on our ability to attract, develop 
and retain our employees. Diversity and inclusion are foundational to our leadership approach and our focus is on how our 
actions and the actions of our employees foster diversity and inclusion in our everyday activities at Archrock. We support 
diversity in hiring and gender pay equity, as is reflected in the diversity of our Board of Directors, of which two of nine 
directors  are  female, and of  our executive leadership team,  one  third  of  which is  female.  In addition,  Leonard  Mallett 
joined  our  Board  of  Directors  in  January  2021,  further  enhancing  the  industry  experience,  leadership  experience  and 
diversity of our Board of Directors. 

We believe we offer competitive and comprehensive compensation and benefits packages that include annual bonuses, 
stock  awards,  an  employee  stock  purchase  plan,  a  401(k)  plan  with  employer  contribution,  healthcare  and  insurance 
benefits,  health  savings  and  flexible  spending  accounts  with  employer  contribution,  paid  time  off,  family  leave,  an 
employee assistance program and tuition assistance, among many others.  

We  believe  in  the  ultimate  goal  of  serving  as  the  best  corporate  citizen  possible  and  are  dedicated  to  inspiring  and 
empowering our employees to operate day in and day out according to our core values of safety, service, integrity, respect 
and pride. To that end, the Nominating and Corporate Governance Committee of our Board of Directors provides oversight 
of our policies, practices and programs regarding the promotion of diversity and inclusion within our company and the 
health and safety of our employees and communities. 

Safety, Health and Wellness 

The success of our business is fundamentally connected to the well-being of our people and so we are committed to the 
safety, health and wellness of our employees.  

Safety is a core value of our company, and safety performance is a key measure of success that has been included in our 
short-term  incentive  program  for  over  14  years.  We  actively  promote  the  highest  standards  of  safety  behavior  and 
environmental awareness and strive to meet or exceed all applicable local and national regulations. “Stop the Job” is an 
adopted edict that establishes the obligation of and provides the authority to all employees to stop any task or operation 
where they perceive that a risk to people, the environment or assets is not properly controlled. We believe that all incidents 
are preventable and that through proper training, planning and hazard recognition, we can achieve a workplace with zero 
incidents. To this end, we created the TARGET ZERO program that includes over 90 safety and environmental procedures, 
and their necessary tools, equipment and training, that are designed to foster a mindset that integrates safety into every 
work process. Through this program, we successfully lowered our total recordable incident rate from 0.54 in 2019 to 0.25 
in 2020, and it will be our continuous goal that we achieve a rate of zero in all future periods.

We also provide our employees and their families with access to a variety of flexible and convenient health and wellness 
programs  that  support  the  maintenance  or  improvement  of  our  employees’  physical  and  mental  health  and  encourage 
engagement in healthy  behaviors, including  our  employee-led  RockFIT  program  that  develops and  sponsors corporate 
health and fitness challenges throughout the year. 

Response to COVID-19 Pandemic 

We  took  swift  action  regarding  employee  well-being  in  response  to  the  COVID-19  pandemic,  establishing  a 
multidisciplinary  team,  with  representation  from  human  resources,  health  safety  and  environment,  facilities  and 
information technology, to develop a pandemic response plan. We implemented comprehensive protocols to protect the 
health and safety of our employees, customers and communities, including contactless parts pickup for field employees 
and customers and mandated social distancing and additional personal protection equipment requirements in the field. We 
adopted remote work for office-based employees and all travel deemed non-essential was eliminated. Employees began 
returning to the office, capped at 50% capacity, in the latter part of 2020. We implemented daily temperature checks and 
provided increased signage, sanitizer, fresh air flow, personal protective equipment and frequent cleaning services at all 
office locations. 

Talent Development 

We  invest  significant  resources  to  develop  the  talent  needed  to  provide  our  industry-leading  natural  gas  compression 
services. We work closely with suppliers to develop training programs for our field service technicians. Our field service 
technicians are supported by a dedicated training team and collectively completed over 18,000 hours of operational and 
technical training during 2020. Every new hire field employee enters a program whereby they are assigned an experienced 
mentor, for an average of six months, under whose direct supervision they apply their classroom learning in the real world 
setting.  

In addition, we offer a number of non-technical, targeted skills-based and career-enhancing training programs, including 
technical orientation for non-technical employees, supervisor coaching, performance management and conflict resolution. 
Our talent development programs provide employees with the resources they need to help achieve their career goals, build 
management skills and lead their organizations. 

Building Employee and Community Connections 

We consider ourselves a member of every community in which we operate and believe that building connections between 
our employees, their families and our communities creates a more meaningful and enjoyable workplace. Our employees 
give generously and are passionate towards many causes, for which they receive annual paid time off to volunteer. Our 
employee-led  Archrock  Cares  program  brings  together  employees  across  functions  and  backgrounds  to  break  down 
traditional corporate barriers and form strong bonds through the pursuit of shared interests and volunteering and giving 
opportunities across the country.

Item 1A. Risk Factors 

As described in “Forward-Looking Statements,” this 2020 Form 10-K contains forward-looking statements regarding us, 
our  business and our  industry. The  risk  factors  described  below,  among others, could  cause  our  actual results  to differ 
materially from the expectations reflected in the forward-looking statements. If any of the following risks actually occur, 
our business, financial condition, results of operations and cash flows could be negatively impacted. 

Industry and General Economic Risks 

The COVID-19 pandemic is expected to continue to significantly reduce demand for our services, and may continue to 
have a material adverse impact on our financial condition, results of operations and cash flows. 

The  effects  of  the  COVID-19  pandemic,  including  actions  taken  by  businesses  and  governments,  have  resulted  in  a 
significant and swift reduction in U.S. economic activity. These effects have materially adversely affected the demand for 
oil and, to a lesser extent, natural gas, and have had, and are expected to continue to have, a negative impact on demand 
for our services and products. The collapse in the demand for oil caused by this unprecedented global health and economic 
crisis, coupled with oil oversupply, is expected to continue to adversely impact the demand for our services, which in turn 
could adversely impact our financial condition, results of operations and cash flows. 

While the magnitude and duration of potential social, economic and labor instability as a direct result of the COVID-19 
pandemic cannot be estimated at this time, we are closely monitoring the effects of the pandemic on commodity demands 
and on our customers, as well as on our operations and employees. These effects may include adverse revenue and net 
income  effects;  disruptions  to  our  operations  and  supply  chain;  customer  shutdowns  of  oil  and  gas  exploration  and 
production;  employee  impacts  from  illness,  school  closures  and  other  community  response  measures;  and  temporary 
inaccessibility or closures of our facilities or the facilities of our customers and suppliers. 

The extent to which our operating and financial results continue to be affected by the COVID-19 pandemic will depend 
on various factors and consequences beyond our control, such as the duration and scope of the pandemic; additional actions 
by businesses and governments in response to the pandemic; and the speed and effectiveness of responses to combat the 
virus. The COVID-19 pandemic may materially adversely affect our operating and financial results in a manner that is not 
currently known to us or that we do not currently consider to present significant risks to our operations. 

Business and Operational Risks 

Our operations entail inherent risks that may result in substantial liability. We do not insure against all potential losses 
and could be seriously harmed by unexpected liabilities. 

Our operations entail inherent risks, including equipment defects, malfunctions and failures and natural disasters, which 
could result in uncontrollable flows of natural gas or well fluids, fires and explosions. These risks may expose us, as an 
equipment operator, to liability for personal injury, wrongful death, property damage, pollution and other environmental 
damage.  The  insurance  we  carry  against  many  of  these  risks  may  not  be  adequate  to  cover  our  claims  or  losses.  Our 
insurance coverage includes property damage, general liability and commercial automobile liability and other coverage 
we believe is appropriate. Additionally, we are substantially self-insured for workers’ compensation and employee group 
health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these 
risks. We are also self-insured for property damage to our offshore assets. Further, insurance covering the risks we expect 
to  face  or  in  the  amounts  we  desire  may  not  be  available  in  the  future  or,  if  available,  the  premiums  may  not  be 
commercially justifiable. If we were to incur substantial liability and such damages were not covered by insurance or were 
in excess of policy limits, or if we were to incur liability at a time when we are not able to obtain liability insurance, our 
business, results of operations and financial condition could be negatively impacted.

We face significant competitive pressures that may cause us to lose market share and harm our financial performance. 

Our business is highly competitive and there are low barriers to entry. Our competitors may be able to more quickly adapt 
to technological changes within our industry and changes in economic and market conditions as a whole, more readily 
take advantage of acquisitions and other opportunities and adopt more aggressive pricing policies. Our ability to renew or 
replace existing contract operations service contracts with our customers at rates sufficient to maintain current revenue 
and cash flows could be adversely affected by the activities of our competitors. If our competitors substantially increase 
the resources they devote to the development and marketing of competitive products, equipment or services or substantially 
decrease the price at which they offer their products, equipment or services, we may not be able to compete effectively. 

In addition, we could face significant competition from new entrants into the compression services business. Some of our 
existing competitors or new entrants may expand or fabricate new compressors that would create additional competition 
for the services we provide to our customers. In addition, our customers may purchase and operate their own compression 
fleets  in  lieu  of  using  our  natural  gas  compression  services.  We  also  may  not  be  able  to  take  advantage  of  certain 
opportunities or make certain investments because of our debt levels and our other obligations. Any of these competitive 
pressures could have a material adverse effect on our business, results of operations and financial condition. 

If we do not make acquisitions on economically acceptable terms, our future growth could be limited. 

Our ability  to  grow  depends,  in  part,  on  our  ability to  make accretive acquisitions.  If  we are unable to  make  accretive 
acquisitions either because we are (i) unable to identify attractive acquisition candidates or negotiate acceptable purchase 
contracts with them, (ii) unable to obtain financing for these acquisitions on economically acceptable terms or (iii) outbid 
by competitors, then our future growth and ability to maintain dividends could be limited. Furthermore, even if we make 
acquisitions that we believe will be accretive, these acquisitions may nevertheless result in a decrease in the cash generated 
from operations per unit. 

Any acquisition involves potential risks, including, among other things: 

an inability to integrate successfully the businesses we acquire; 
the assumption of unknown liabilities; 
limitations on rights to indemnity from the seller; 

•(cid:1)
•(cid:1)
•(cid:1)
•(cid:1) mistaken assumptions about the cash generated or anticipated to be generated by the business acquired or the 

overall costs of equity or debt; 
the diversion of management’s attention from other business concerns; 
unforeseen operating difficulties; and 
customer or key employee losses at the acquired businesses. 

•(cid:1)
•(cid:1)
•(cid:1)

If we consummate any future acquisitions, our capitalization and results of operations may change significantly and we 
will not have the opportunity to evaluate the economic, financial and other relevant information that we will consider in 
determining  the application  of  our  future  funds and other  resources.  In  addition,  competition  from  other  buyers  could 
reduce our acquisition opportunities or cause us to pay a higher price than we might otherwise pay. 

Following the closing of the Elite Acquisition, an affiliate of Hilcorp holds a significant portion of our common stock, 
and Hilcorp’s interest as an equity holder may conflict with the interests of our other shareholders or our noteholders. 

In connection with the closing of the Elite Acquisition, JDH Capital, an affiliate of Hilcorp, received 21.7 million shares 
of our common stock, representing 14.2% of our outstanding common stock as of December 31, 2020. As long as JDH 
Capital, together with affiliates of Hilcorp, owns at least 7.5% of our outstanding common stock, it will have the right to 
nominate one director to our Board of Directors. Given its ownership level and board representation, JDH Capital may 
have some influence over our operations and strategic direction and may have interests that conflict with the interests of 
other equity and debt holders.

While we paid quarterly dividends of $0.145 per share of common stock during the year ended December 31, 2020, 
there can be no assurance that we will pay dividends in the future. 

We paid quarterly cash dividends of $0.145 per share of common stock during the year ended December 31, 2020. We 
cannot  provide  assurance  that  we  will,  at  any  time  in  the  future,  again  generate  sufficient  surplus  cash  that  would  be 
available for distribution to the holders of our common stock as a dividend or that our Board of Directors would determine 
to use any such surplus or our net profits to pay a dividend. 

Future dividends may be affected by, among other factors: 

•(cid:1)

•(cid:1)
•(cid:1)
•(cid:1)
•(cid:1)
•(cid:1)
•(cid:1)
•(cid:1)

•(cid:1)

the availability of surplus or net profits, which in turn depend on the performance of our business and operating 
subsidiaries; 
our debt service requirements and other liabilities; 
our ability to refinance our debt in the future or borrow funds and access capital markets; 
restrictions contained in our debt agreements; 
our future capital requirements, including to fund our operating expenses and other working capital needs; 
the rates we charge for our services; 
the level of demand for our services;
the creditworthiness of our customers; 
our level of operating expenses; and 
changes in U.S. federal, state and local income tax laws or corporate laws. 

We  cannot  provide assurance  that  we  will  declare  or  pay  dividends in any  particular  amount or at  all in  the  future.  A 
decision not to pay dividends or a reduction in our dividend payments in the future could have a negative effect on our 
stock price. 

Financial Risks 

We have a substantial amount of debt that could limit our ability to fund future growth and operations and increase 
our exposure to risk during adverse economic conditions. 

At  December 31, 2020,  we  had  $1.7  billion  in  outstanding  debt  obligations,  net  of  unamortized  debt  discounts  and 
unamortized deferred financing costs. Many factors, including factors beyond our control, may affect our ability to make 
payments on our outstanding indebtedness. These factors include those discussed elsewhere in these Risk Factors. 

Our substantial debt and associated commitments could have important adverse consequences to our liquidity, particularly 
to the extent our borrowing capacity becomes covenant restricted. For example, these commitments could: 

• make it more difficult for us to satisfy our contractual obligations;
•(cid:1)
•(cid:1)
•(cid:1)

increase our vulnerability to general adverse economic and industry conditions; 
limit our ability to fund future working capital, capital expenditures, acquisitions or other corporate requirements; 
increase our vulnerability to interest rate fluctuations because the interest payments on a portion of our debt are 
based upon variable interest rates and a portion can adjust based on our credit statistics; 
limit our flexibility in planning for, or reacting to, changes in our business and our industry; 
place us at a disadvantage compared to our competitors that have less debt or less restrictive covenants in such 
debt; and 
limit our ability to incur indebtedness in the future.

Covenants in our Debt Agreements may impair our ability to operate our business. 

Our Debt Agreements contain various covenants with which we or certain of our subsidiaries must comply, including, but 
not  limited  to,  restrictions  on  the  use  of  proceeds  from  borrowings,  limitations  on  the  incurrence  of  indebtedness, 
investments,  acquisitions,  making  loans,  liens  on  assets,  repurchasing  equity,  making  dividends  or  distributions, 
transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types 
of agreements. The Debt Agreements also contain various covenants requiring mandatory prepayments from the net cash 
proceeds of certain asset transfers. 

The Credit Facility is also subject to financial covenants, including the following ratios after giving effect to Amendment 
No. 3, as defined in the corresponding agreement: 

EBITDA to Interest Expense 
Senior Secured Debt to EBITDA 
Total Debt to EBITDA 

Through fiscal year 2022 
January 1, 2023 through September 30, 2023 
Thereafter (1) 

2.5 to 1.0 
3.0 to 1.0 

5.75 to 1.0 
5.50 to 1.0 
5.25 to 1.0 

(1)(cid:1)

Subject to a temporary increase to 5.50 to 1.0 for any quarter during which an acquisition satisfying certain thresholds is completed and for the two 
quarters immediately following such quarter. 

If  we  were to  anticipate non-compliance  with  these  financial  ratios,  we  may  take actions  to  maintain compliance  with 
them. These actions include reductions in its general and administrative expenses, capital expenditures or the payment of 
cash  distributions.  Any of  these  measures  may  reduce  the amount of  cash available  for  payment  of dividends  and  the 
funding of our business requirements, which could have an adverse effect on our business, operations, cash flows or the 
price of our common stock. 

The breach of any of the covenants under the Debt Agreements could result in a default under the Debt Agreements, which 
could cause indebtedness under the Debt Agreements to become due and payable. If the repayment obligations under the 
Debt Agreements were to be accelerated, we may not be able to repay the debt or refinance the debt on acceptable terms 
and  our  financial  position  would  be  materially  adversely  affected.  A  material  adverse  effect  on  our  assets,  liabilities, 
financial condition, business or operations that, taken as a whole, impacts our ability to perform the obligations under the 
Debt  Agreements  could  lead  to  a  default  under  those  agreements.  Further,  a  default  under  one  or  more  of  the  Debt 
Agreements  would  trigger  cross-default  provisions  under  the  other  Debt  Agreements,  which  would  accelerate  our 
obligation to repay the indebtedness under those agreements. 

As of December 31, 2020, we were in compliance with all covenants under the Debt Agreements. 

We may be unable to access the capital and credit markets or borrow on affordable terms to obtain additional capital 
that we may require. 

Historically, we have financed acquisitions, operating expenditures and capital expenditures with a combination of cash 
provided by operating and financing activities. However, to the extent we are unable to finance our operating expenditures, 
capital expenditures, scheduled interest and debt repayments and any future dividends with net cash provided by operating 
activities and borrowings under the Credit Facility, we may require additional capital. Periods of instability in the capital 
and credit  markets  (both generally and in  the  oil  and  gas industry  in  particular)  could  limit  our  ability  to  access these 
markets to  raise debt  or equity capital  on  affordable  terms  or  to  obtain additional  financing.  Among  other  things, our 
lenders may seek to increase interest rates, enact tighter lending standards, refuse to refinance existing debt at maturity at 
favorable terms or at all and may reduce or cease to provide funding to us. If we are unable to access the capital and credit 
markets on favorable terms, or if we are not successful in raising capital within the time period required or at all, we may 
not  be  able  to  grow  or  maintain  our  business,  which  could  have  a  material  adverse  effect  on  our  business,  results  of 
operations and financial condition.

Our inability to fund purchases of additional compression equipment could adversely impact our financial results. 

We may not be able to maintain or increase our asset and customer base unless we have access to sufficient capital to 
purchase additional compression equipment. Cash flow from our operations and availability under our Credit Facility may 
not  provide  us  with  sufficient  cash  to  fund  our  capital  expenditure  requirements,  including  any  funding  requirements 
related to acquisitions. Our ability to grow our asset and customer base could be impacted by limits on our ability to access 
additional capital. 

We may be vulnerable to interest rate increases due to our variable rate debt obligations. 

As  of  December 31, 2020,  after  taking  into  consideration  interest  rate  swaps,  we  had  $93.0  million  of  outstanding 
indebtedness that was effectively subject to variable interest rates. Changes in economic conditions outside of our control 
could result in higher interest rates, thereby increasing our interest expense and reducing the funds available for capital 
investment, operations or other purposes. A 1% increase in the effective interest rate on our outstanding debt subject to 
variable interest rates at December 31, 2020 would result in an annual increase in our interest expense of $0.9 million. In 
addition, a substantial portion of our cash flow must be used to service our debt obligations. Any increase in our interest 
expense could negatively impact our results of operations and cash flows, including our ability to pay dividends in the 
future. 

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR after 2021 may adversely 
affect the market value of our current or future debt obligations, including our Credit Facility.  

On July 27, 2017, the FCA announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 
2021. As a result, LIBOR may be discontinued by 2022. Furthermore, in the U.S., efforts to identify a set of alternative 
U.S.  dollar  reference  interest  rates  that  could  replace  LIBOR  include  proposals  by  the  Alternative  Reference  Rates 
Committee  of  the  Federal Reserve  Board and the  Federal Reserve  Bank of  New  York.  In addition,  any  other  legal  or 
regulatory changes made by the FCA, ICE Benchmark Administration Limited, the European Money Markets Institute 
(formerly  Euribor-EBF),  the  European  Commission  or  any  other  successor  governance  or  oversight  body,  or  future 
changes adopted by such body, in the method by which LIBOR is determined or the transition from LIBOR to a successor 
benchmark  may  result  in,  among  other  things,  a  sudden  or  prolonged  increase  or  decrease  in  LIBOR,  a  delay  in  the 
publication of LIBOR and changes in the rules or methodologies in LIBOR, which may discourage market participants 
from continuing to administer or to participate in LIBOR’s determination. This could result in LIBOR no longer being 
determined  or  published.  If  a published  U.S.  dollar LIBOR  rate  is  unavailable  after  2021,  the  interest  rate  paid  on  our 
current  or  future debt  obligations,  including the  Credit  Facility,  will  need to  be determined using  alternative  methods, 
which may result in interest obligations which are more than or do not otherwise correlate over time with the payments 
that would have been made on any current of future debt obligations, including the Credit Facility, if U.S. dollar LIBOR 
was available in its current form. 

At this time, it is not possible to predict whether any such changes will occur, whether LIBOR will be phased out or any 
such alternative reference rates or other reforms to LIBOR will be enacted in the United Kingdom, the U.S. or elsewhere 
or the effect that any such changes, phase out, alternative reference rates or other reforms, if they occur, would have on 
the amount of interest paid on, or the market value of, our current or future debt obligations, including the Credit Facility. 
Uncertainty as to the nature of such potential changes, phase out, alternative reference rates or other reforms may materially 
adversely affect the terms of the Credit Facility and any interest rate swaps or other derivative agreements to which we are 
a  party.  Reform  of,  or  the  replacement  or  phasing  out  of,  LIBOR  and  proposed  regulation  of  LIBOR  and  other 
“benchmarks” may materially adversely affect the market value of, the applicable interest rate on and the amount of interest 
paid on  our current  or  future  debt  obligations, including the  Credit  Facility.  In addition,  even  if  we  have  entered into 
interest  rate  swaps  or  other  derivative  instruments  for  purposes  of  managing  our  interest  rate  exposure,  our  hedging 
strategies may not be effective as a result of the replacement or phasing out of LIBOR and other “benchmarks” and we 
may incur substantial losses as a result.

Customer and Contract Risks 

The erosion of the financial condition of our customers could adversely affect our business. 

Many  of  our  customers  finance  their  exploration  and  production  activities  through  cash  flow  from  operations,  the 
incurrence of debt or the issuance of equity. During times when the oil or natural gas markets weaken, our customers are 
more likely to experience a downturn in their financial condition. Additionally, some of our midstream customers may 
provide their gathering, transportation and related services to a limited number of companies in the oil and gas production 
business. A reduction in borrowing bases under reserve-based credit facilities, the lack of availability of debt or equity 
financing  or  other  factors  that  negatively  impact  our  customers’  financial  condition  could  result  in  a  reduction  in  our 
customers’ spending for our products and services, which may result in their cancellation of contracts, the cancellation or 
delay of scheduled maintenance of their existing natural gas compression equipment, their determination not to enter into 
new  natural  gas  compression  service  contracts  or  their  determination  to  cancel  or  delay  orders  for  our  services. 
Furthermore, the loss by our midstream customers of their key customers could reduce demand for their services and result 
in a deterioration of their financial condition, which would in turn decrease their demand for our services. Any such action 
by  our customers  would  reduce  demand  for  our  services. Reduced  demand  for  our  services  could adversely affect  our 
business, results of operations, financial condition and cash flows. In addition, in the event of the financial failure of a 
customer,  we  could  experience  a  loss  on  all  or  a  portion  of  our  outstanding  accounts  receivable  associated  with  that 
customer. 

The loss of any of our most significant customers would result in a decline in our revenue and cash available to pay 
dividends to our common stockholders. 

Our five most significant customers collectively accounted for 28%, 25% and 26% of our revenue for the years ended 
December 31, 2020,  2019  and  2018,  respectively.  Our  services  are  provided  to  these  customers  pursuant  to  contract 
compression services agreements, which typically have an initial term of 12 to 48 months and continue thereafter until 
terminated by either party with 30 days’ advance notice. The loss of all or even a portion of the services we provide to 
these customers, as a result of competition or otherwise, could have a material adverse effect on our business, results of 
operations and financial condition. 

Many of our contract operations services contracts have short initial terms and are cancelable on short notice after the 
initial term, and we cannot be sure that such contracts will be extended or renewed after the end of the initial contractual 
term. Any such nonrenewals, or renewals at reduced rates or the loss of contracts with any significant customer could 
adversely impact our results of operations. 

The length of our contract operations services contracts with customers varies based on operating conditions and customer 
needs. Our initial contract terms typically are not long enough to enable us to recoup the cost of the equipment we utilize 
to provide contract operations services and these contracts are typically cancelable on short notice after the initial term. 
We cannot be sure that a substantial number of these contracts will be extended or renewed by our customers or that any 
of our customers will continue to contract with us. The inability to negotiate extensions or renew a substantial portion of 
our  contract  operations  services  contracts,  the  renewal  of  such  contracts  at  reduced  rates,  the  inability  to  contract  for 
additional services with our customers or the loss of all or a significant portion of our services contracts with any significant 
customer could lead to a reduction in revenue and net income and could require us to record asset impairments. This could 
have a material adverse effect upon our business, results of operations, financial condition and cash flows. 

Labor and Supply Chain Risks 

Our ability to manage and grow our business effectively may be adversely affected if we lose management or operational 
personnel. 

We believe that our ability to hire, train and retain qualified personnel will continue to be challenging and important. The 
supply of experienced operational and field personnel, in particular, decreases as other energy companies’ needs for the 
same personnel increase. Our ability to grow and to continue our current level of service to our customers will be adversely 
impacted if we are unable to successfully hire, train and retain these important personnel.

23 

Table of Contents

We depend on particular suppliers and are vulnerable to product shortages and price increases. With respect to our 
suppliers  of  newly-fabricated  compression  equipment  specifically,  we  occasionally  experience  long  lead  times,  and 
therefore may at times make purchases in anticipation of future business. If we are unable to purchase compression 
equipment or other integral equipment, materials and services from third party suppliers, we may be unable to retain 
existing customers or compete for new customers, which could have a material adverse effect on our business, results 
of operations and financial condition. 

Some equipment, materials and services used in our business are obtained from a limited group of suppliers. Our reliance 
on these suppliers involves several risks, including price increases, inferior quality and a potential inability to obtain an 
adequate supply of such equipment, materials and services in a timely manner. Additionally, we occasionally experience 
long  lead  times  from  our  suppliers  of  newly-fabricated  compression  equipment  and  may  at  times  make  purchases  in 
anticipation  of  future  business.  We  do  not  have  long-term  contracts  with  some  of  these  suppliers,  and  the  partial  or 
complete loss of certain of these suppliers could have a negative impact on our results of operations and could damage our 
customer relationships. Further, a significant increase in the price of such equipment, materials and services could have a 
negative impact on our results of operations. 

If we are unable to purchase compression equipment in particular on a timely basis to meet the demands of our customers, 
our existing customers may terminate their contractual relationships with us, or we may not be able to compete for business 
from  new  or existing  customers,  which, in each case, could  have  a  material adverse effect  on  our  business,  results  of 
operations and financial condition. 

Information Technology and Cybersecurity Risks 

We may not realize the intended benefits of our technology transformation project, which could have an adverse effect 
on our business. 

In the fourth quarter of 2018, we began a process and technology transformation project that will, among other things, 
upgrade or replace our existing ERP, supply chain and inventory management systems and expand the remote monitoring 
capabilities of our compression fleet. By using technology to make our systems and processes more efficient, we intend to 
lower  our  internal  costs  and  improve  our  profitability  over  time.  However,  the  implementation  of  the  technology 
transformation  project  requires  capital  and  other  resources,  and  we  anticipate  that  the  project  will  continue  to  require 
significant resources and result in increased SG&A expense and capital expenditures in 2021. Further, we may not realize 
the benefits we expect to realize from the technology transformation project. Any such difficulties could have an adverse 
effect on our business, results of operations and financial condition. 

Threats of cyber-attacks or terrorism could affect our business. 

We may be threatened by problems such as cyber-attacks, computer viruses or terrorism that may disrupt our operations 
and harm our operating  results.  Our  industry  requires the  continued  operation  of  sophisticated  information  technology 
systems  and  network  infrastructure.  Despite  our  implementation  of  security  measures,  our  technology  systems  are 
vulnerable to disability or failures due to hacking, viruses, acts of war or terrorism and other causes. If our information 
technology  systems  were  to  fail and  we  were  unable to  recover  in  a  timely  way,  we  might be  unable to  fulfill critical 
business  functions,  which  could  have  a  material  adverse  effect  on  our  business,  results  of  operations  and  financial 
condition. 

In addition, our assets may be targets of terrorist activities that could disrupt our ability to service our customers. We may 
be required by our regulators or by the future terrorist threat environment to make investments in security that we cannot 
currently predict. The implementation of security guidelines and measures and maintenance of insurance, to the extent 
available,  addressing  such  activities  could  increase  costs.  These  types  of  events  could  materially  adversely  affect  our 
business and results of operations. In addition, these types of events could require significant management attention and 
resources and could adversely affect our reputation among customers and the public.

Tax-related Risks 

Tax legislation and administrative initiatives or challenges to our tax positions could adversely affect our results of 
operations and financial condition. 

We operate in locations throughout the U.S. and, as a result, we are subject to the tax laws and regulations of U.S. federal, 
state and local governments. From time to time, various legislative or administrative initiatives may be proposed that could 
adversely affect our tax positions. There can be no assurance that our tax provision or tax payments will not be adversely 
affected by these initiatives. In addition, U.S. federal, state and local tax laws and regulations are extremely complex and 
subject to varying interpretations. There can be no assurance that our tax positions will not be challenged by relevant tax 
authorities or that we would be successful in any such challenge. 

Our ability to use NOLs to offset future income may be limited. 

Our ability to use any NOLs generated by us could be substantially limited if we were to experience an “ownership change” 
as defined under Section 382 of the Code. In general, an “ownership change” would occur if our “5-percent stockholders,” 
as  defined  under  Section 382  of  the  Code,  including  certain  groups  of  persons  treated  as  “5-percent  stockholders,” 
collectively  increased  their  ownership  in  us  by  more  than  50 percentage  points  over  a  rolling  three-year  period.  An 
ownership change can occur as a result of a public offering of our common stock, as well as through secondary market 
purchases of our common stock and certain types of reorganization transactions. We have experienced ownership changes, 
which may result in an annual limitation on the use of its pre-ownership change NOLs (and certain other losses and/or 
credits) equal to the equity value of our stock immediately before the ownership change, multiplied by the long-term tax-
exempt  rate  for  the month  in  which  the  ownership  change  occurs.  Due  to  the  COVID-19  pandemic,  the  U.S.  Federal 
Reserve  has  lowered  the  long-term  tax-exempt  rate.  Market  volatility  due  to  reduced  demand  from  the  COVID-19 
pandemic and oil oversupply and the related decrease in our equity value may cause increased interest in our common 
stock,  which  may  result  in  an  additional  ownership  change.  Both  of  these  changes  could  further  limit  our  use  of  pre-
ownership change NOLs if we experienced an additional ownership change. Furthermore, the IRS has recently proposed 
regulations that would prevent us from using unrealized built-in gains to increase this limitation. If these regulations were 
finalized and we experienced an ownership change our ability to use our NOLs may be limited. Such a limitation could, 
for any given year, have the effect of increasing the amount of our U.S. federal income tax liability, which would negatively 
impact the amount of after-tax cash available for distribution to our stockholders and our financial condition. 

We are subject to continuing contingent tax liabilities following the Spin-off. 

In  connection  with the  Spin-off,  we entered  into a tax  matters  agreement  with  Exterran Corporation that allocates  the 
responsibility  for  prior  period taxes  of  the  Exterran  Holdings  consolidated  U.S.  federal  and  state  tax  reporting  group 
between  us and Exterran Corporation.  If  Exterran  Corporation is  unable to  pay  any  prior  period taxes  related to these 
consolidated U.S. federal and state tax filings for which it is responsible, we would be required to pay the entire amount 
of such taxes. 

We might not be able to engage in desirable strategic transactions and equity issuances because of certain restrictions 
relating to requirements for tax-free distributions. 

Our ability to engage in significant equity transactions could be limited or restricted in order to preserve, for U.S. federal 
income tax purposes, the tax-free nature of the Spin-off. Even if the Spin-off otherwise qualifies for tax-free treatment 
under Section 355 of the Code, it may result in corporate-level taxable gain to us under Section 355(e) of the Code if there 
is a 50% or greater change in ownership, by vote or value, of shares of our stock, Exterran Corporation’s stock or the stock 
of a successor either occurring as part of a plan or series of related transactions that includes the Spin-off. 

Under the tax matters agreement that we entered into with Exterran Corporation, we are prohibited from taking or failing 
to take any action that prevents the Spin-off from being tax-free. 

25 

Table of Contents

These restrictions may limit our ability to pursue strategic transactions or engage in new business or other transactions that 
may maximize the value of our business. Moreover, the tax matters agreement also may provide that we are responsible 
for any taxes imposed on us or any of our affiliates as a result of the failure of the Spin-off to qualify for favorable treatment 
under the Code if such failure is attributable to certain actions taken after the Spin-off by or in respect of us, any of our 
affiliates or our shareholders. 

Legal and Regulatory Risks 

From time to time, we are subject to various claims, tax audits, litigation and other proceedings that could ultimately 
be  resolved  against  us  and  require  material  future  cash  payments  or  charges,  which  could  impair  our  financial 
condition or results of operations. 

The size, nature and complexity of our business make us susceptible to various claims, tax audits, litigation and binding 
arbitration proceedings. We are currently, and may in the future become, subject to various claims, which, if not resolved 
within amounts we have accrued, could have a material adverse effect on our financial position, results of operations or 
cash  flows,  including  our  ability  to  pay  dividends.  Similarly,  any  claims,  even  if  fully  indemnified  or  insured,  could 
negatively  impact  our  reputation  among  our  customers  and  the  public,  and  make  it  more  difficult  for  us  to  compete 
effectively or obtain adequate insurance in the future. See Part I Item 3 “Legal Proceedings” and Note 26 (“Commitments 
and Contingencies”) to our Financial Statements for additional information regarding certain legal proceedings to which 
we are a party. 

U.S.  federal,  state  and  local  legislative  and  regulatory  initiatives  relating  to  hydraulic  fracturing  as  well  as 
governmental reviews of such activities could result in increased costs and additional operating restrictions or delays 
in the completion of oil and natural gas wells and adversely affect demand for our contract operations services. 

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. We do not perform hydraulic fracturing, but many of our customers do. Hydraulic 
fracturing involves the injection of water, sand or alternative proppant and chemicals under pressure into target geological 
formations to fracture the surrounding rock and stimulate production. Hydraulic fracturing is typically regulated by state 
agencies, but recently, there has been increased public concern regarding an alleged potential for hydraulic fracturing to 
adversely  affect  drinking  water  supplies,  and  proposals  have  been  made to  enact  separate  U.S.  federal,  state  and local 
legislation that would increase the regulatory burden imposed on hydraulic fracturing. 

For  example, at  the  U.S. federal  level,  the  EPA  issued  an Advance  Notice of  Proposed  Rulemaking to  collect data  on 
chemicals  used  in  hydraulic  fracturing  operations  under  Section 8  of  the  Toxic  Substances  Control  Act  and  proposed 
regulations  under  the  CWA  governing  wastewater  discharges  from  hydraulic  fracturing  and  certain  other  natural  gas 
operations. On March 26, 2015, the BoLM released a final rule that updates existing regulation of hydraulic fracturing 
activities  on  U.S.  federal  lands,  including  requirements  for  chemical  disclosure,  wellbore  integrity  and  handling  of 
flowback  water. The  final  rule never  went into effect  due to  pending  litigation and on  December 28,  2017,  the  BoLM 
announced that it had rescinded the 2015 final rule, in part citing a review that found that 32 of the 32 states with federal 
oil and gas leases have regulations that already address hydraulic fracturing. 

On January 27, 2021, the new administration issued an executive order directing the Secretary of the Interior to pause all 
new oil and natural gas leases on public lands or in offshore waters pending completion of a comprehensive review and 
reconsideration  of  federal  oil  and  gas  permitting  and  leasing  practices  in  light  of  potential  climate  and  other  impacts 
associated with oil and natural gas activities thereon. Legal challenges to the suspension have already been filed and are 
currently pending. 

26 

Table of Contents

At  the  state  level,  several  states  have  adopted  or  are  considering  legal  requirements  that  could  impose  more  stringent 
permitting, disclosure and well construction requirements on hydraulic fracturing activities. For example, in May 2013, 
the Texas Railroad Commission adopted new rules governing well casing, cementing and other standards for ensuring that 
hydraulic fracturing operations do not contaminate nearby water resources. Local governments may also seek to adopt 
ordinances within their jurisdictions regulating the time, place and manner of drilling activities in general or hydraulic 
fracturing activities in particular or prohibit the performance of well drilling in general or hydraulic fracturing in particular. 
If new or more stringent U.S. federal, state or local legal restrictions relating to the hydraulic fracturing process are adopted 
in  areas  where  our  natural  gas  exploration  and  production  customers  operate,  those  customers  could  incur  potentially 
significant added costs to comply with such requirements, experience delays or curtailment in the pursuit of exploration, 
development or production activities and perhaps even be precluded from drilling wells. Any such restrictions could reduce 
demand for our contract operations services, and as a result could have a material adverse effect on our business, financial 
condition, results of operations and cash flows. 

New  regulations,  proposed  regulations  and  proposed  modifications  to  existing  regulations  under  the  CAA,  if 
implemented, could result in increased compliance costs. 

On June 3, 2016, the EPA issued final regulations amending the NSPS for the oil and natural gas source category and 
applying to sources of emissions of methane and VOC from certain processes, activities and equipment that is constructed, 
modified or reconstructed after September 18, 2015. Specifically, the regulation contains both methane and VOC standards 
for several emission sources not previously covered by the NSPS, such as fugitive emissions from compressor stations and 
pneumatic  pumps  and  methane  standards  for  certain  emission  sources  that  are  already  regulated  for  VOC,  such  as 
equipment  leaks  at  natural  gas  processing  plants.  The  amendments  also  establish  methane  standards  for  a  subset  of 
equipment that the current NSPS regulates, including reciprocating compressors and pneumatic controllers, and extend the 
current  VOC  standards  to  the  remaining  unregulated  equipment.  On  August  13,  2020,  the  EPA  adopted  deregulatory 
amendments to the 2016 rule intended to streamline implementation, reduce duplicative EPA and state requirements and 
decrease the burden of compliance. In particular, the amendments removed the transmission and storage segments from 
the oil and natural gas source category and rescinded the methane-specific requirements for production and processing 
facilities. Several lawsuits were filed challenging these amendments, and the U.S. Court of Appeals for the D.C. Circuit 
ordered an administrative stay of these amendments shortly after they were finalized. Although the administrative stay 
was lifted in October 2020, which brought the amendments into effect, the amendments may still be subject to reversal 
under  the  new presidential  administration.  However,  on January  20,  2021,  the new  administration issued  an  executive 
order  calling  on  the  EPA  to,  among  other  things,  consider  a  proposed  rule  suspending,  revising  or  rescinding  those 
deregulatory amendments by September 2021. We do not believe that the current rules will have a material adverse impact 
on our business, financial condition, results of operations or cash flows, but we cannot yet predict the impact, if any, of 
any such suspension, revision or rescinding of the current rules.

On  November 18,  2016,  the  BoLM  published  final  rules to reduce  venting  and  flaring  on  federal and  tribal  lands.  The 
rules set  forth  some  novel  requirements  regarding  leak  detection  inspections  at  compressor  stations  and  imposed 
requirements to reduce emissions from pneumatic controllers and pumps, among other things. While the BoLM adopted a 
rule in  2018  rescinding  most  of  these  requirements,  that  2018  rule  was  challenged  in  court  and  vacated  in  July  2020. 
Following that ruling, another court, which had been hearing challenges to the original 2016 rule, acted on some pending 
litigation in October 2020 and vacated much of the 2016 rule.

On  October 1,  2015,  the  EPA issued a  new  NAAQS  ozone  standard  of  70  ppb,  which  is a  tightening  from  the  75 ppb 
standard  set in  2008.  This  new  standard  became effective  on  December 28,  2015, and  the EPA completed designating 
attainment/non-attainment regions under the revised ozone standard in 2018. In November 2016, the EPA proposed an 
implementation rule for the 2015 NAAQS ozone standard, but the agency has yet to issue a final implementation rule. 
State  implementation  of  the  revised  NAAQS  could  result  in  stricter  permitting  requirements,  delay  or  prohibit  our 
customers’ ability to obtain such permits and result in increased expenditures for pollution control equipment, the costs of 
which could be significant. By law, the EPA must review each NAAQS every five years. In December 2018 and again in 
December 2020, the EPA announced that it was retaining without revision the 2015 NAAQS ozone standard. However, 
on January 20, 2021, the new administration issued an executive order calling on the EPA to, among other things, propose 
a Federal Implementation Plan in response to the 2016 NAAQS for California, Connecticut, New York, Pennsylvania and 
Texas by January 2022. We do not believe continued implementation of the NAAQS ozone standard will have a material 
adverse impact  on our business, financial condition,  results  of operations or cash  flows, but  we  cannot  yet  predict  the 
impact, if any, of any new Federal Implementation Plan. 

In January 2011, the TCEQ  finalized revisions  to certain  air  permit  programs  that  significantly increase  air  emissions-
related requirements for new and certain existing oil and gas production and gathering sites in the Barnett Shale production 
area.  The  final  rule established  new  emissions  standards  for  engines,  which  could  impact  the  operation  of  specific 
categories of engines by requiring the use of alternative engines, compressor packages or the installation of aftermarket 
emissions control equipment. The rule became effective for the Barnett Shale production area in April 2011, and the lower 
emissions standards will become applicable between 2020 and 2030 depending on the type of engine and the permitting 
requirements. A number of other states where our engines are operated have adopted or are considering adopting additional 
regulations that could impose new air permitting or pollution control requirements for engines, some of which could entail 
material  costs  to  comply.  At  this  time,  however,  we  cannot  predict  whether  any  such  rules would  require  us  to  incur 
material costs. 

New environmental regulations and proposals similar to these, when finalized, and any other new regulations requiring 
the  installation  of  more  sophisticated  pollution  control  equipment  or  the  adoption  of  other  environmental  protection 
measures, could have a material adverse impact on our business, financial condition, results of operations and cash flows. 

We  are  subject  to  a  variety  of  governmental  regulations;  failure  to  comply  with  these  regulations  may  result  in 
administrative, civil and criminal enforcement measures and changes in these regulations could increase our costs or 
liabilities. 

We are subject to a variety of U.S. federal, state and local laws and regulations, including relating to the environment, 
health and safety, labor and employment and taxation. Many of these laws and regulations are complex, change frequently, 
are becoming increasingly stringent, and the cost of compliance with these requirements can be expected to increase over 
time.  Failure  to  comply  with  these  laws  and  regulations  may  result  in  a  variety  of  administrative,  civil  and  criminal 
enforcement measures, including assessment of monetary penalties, imposition of remedial requirements and issuance of 
injunctions as to future compliance. From time to time, as part of our operations, including newly acquired operations, we 
may be subject to compliance audits by regulatory authorities in the various states in which we operate. 

Environmental laws and regulations may, in certain circumstances, impose strict liability for environmental contamination, 
which may render us liable for remediation costs, natural resource damages and other damages as a result of our conduct 
that was lawful at the time it occurred or the conduct of, or conditions caused by, prior owners or operators or other third 
parties. In addition, where contamination may be present, it is not uncommon for neighboring land owners and other third 
parties to file claims for personal injury, property damage and recovery of response costs. Remediation costs and other 
damages arising as a result of environmental laws and regulations, and costs associated with new information, changes in 
existing  environmental  laws  and  regulations  or  the  adoption  of  new  environmental  laws  and  regulations  could  be 
substantial and could negatively impact our financial condition, profitability and results of operations. Moreover, failure 
to comply with these environmental laws and regulations may result in the imposition of administrative, civil and criminal 
penalties and the issuance of injunctions delaying or prohibiting operations.

Table of Contents

We may need to apply for or amend facility permits or licenses from time to time with respect to storm water or wastewater 
discharges, waste handling, or air emissions relating to manufacturing activities or equipment operations, which subjects 
us  to  new  or  revised  permitting  conditions  that  may  be  onerous  or  costly  to  comply  with.  In  addition,  certain  of  our 
customer service arrangements may require us to operate, on behalf of a specific customer, petroleum storage units such 
as underground tanks or pipelines and other regulated units, all of which may impose additional compliance and permitting 
obligations. 

We conduct operations at numerous facilities in a wide variety of locations across the continental U.S. The operations at 
many of these facilities require environmental permits or other authorizations. Additionally, natural gas compressors at 
many  of  our  customers’  facilities  require  individual  air  permits  or  general  authorizations  to  operate  under  various  air 
regulatory  programs  established  by  rule or  regulation.  These  permits  and  authorizations  frequently  contain  numerous 
compliance requirements, including monitoring and reporting obligations and operational restrictions, such as emission 
limits.  Given  the  large  number  of  facilities  in  which  we  operate,  and  the  numerous  environmental  permits  and  other 
authorizations that are applicable to our operations, we may occasionally identify or be notified of technical violations of 
certain requirements existing in various permits or other authorizations. Occasionally, we have been assessed penalties for 
our non-compliance, and we could be subject to such penalties in the future. 

We  routinely  deal  with  natural  gas,  oil  and  other  petroleum  products.  Hydrocarbons  or  other  hazardous  substances  or 
wastes may have been disposed or released on, under or from properties used by us to provide contract operations services 
or  inactive  compression  storage  or  on  or  under  other  locations  where  such  substances  or  wastes  have  been  taken  for 
disposal. These properties may be subject to investigatory, remediation and monitoring requirements under environmental 
laws and regulations. 

The  modification  or  interpretation  of  existing  environmental  laws  or  regulations,  the  more  vigorous  enforcement  of 
existing environmental laws or regulations, or the adoption of new environmental laws or regulations may also negatively 
impact oil and natural gas exploration and production, gathering and pipeline companies, including our customers, which 
in turn could have a negative impact on us. 

Climate change legislation, regulatory initiatives and stakeholder pressures could result in increased compliance costs, 
financial risks and potential reduction in demand for our services.

Climate change legislation and regulatory initiatives may occur from a variety of sources, including international, national, 
regional and state levels of government and associated administrative bodies, seeking to restrict or regulate emissions of 
greenhouse gases, such as carbon dioxide and methane. At the international level, the Paris Agreement, which went into 
effect  in  November  2016,  seeks  to  combat  climate  change  through  the  establishment  of  individually-determined 
greenhouse  gas  emissions  reduction  goals.  U.S.  climate  change  strategy  and  implementation  of  that  strategy  through 
legislation and regulation may change from one administration to the next, as President Biden has recently recommitted 
the U.S. to the Paris Agreement after his predecessor withdrew the U.S. from the agreement. Given this uncertainty, U.S. 
companies may need to remain prepared to comply with requirements arising from participation in the Paris Agreement 
going forward. It has become increasingly likely that the U.S. will develop federal climate legislation in addition to existing 
energy legislation and other initiatives relevant to greenhouse gas emissions issues. Many U.S. states, either individually 
or through multi-state regional initiatives, have begun to address greenhouse gas emissions, primarily through the planned 
development of emission inventories or regional greenhouse gas cap and trade programs. Although most of the state-level 
initiatives  have to  date been  focused  on  large  sources of  greenhouse  gas emissions,  such as  electric  power  plants, it  is 
possible that smaller sources such as our natural gas-powered compressors could become subject to greenhouse gas-related 
regulation. Depending on the particular program, we could be required to control emissions or to purchase and surrender 
allowances for greenhouse gas emissions resulting from our operations.

The legislative landscape continues to change and to be met with legal challenges with respect to climate-related laws and 
regulations, making it difficult to predict with certainty the ultimate impact they will have on the company in the aggregate. 
Although  it  is  not  currently  possible  to  predict  how  any  proposed  or  future  greenhouse  gas  legislation  or  regulation 
promulgated at the international, national, state or local levels will impact our business, any regulation of greenhouse gas 
emissions that may be imposed in areas in which we conduct business could result in increased compliance costs, additional 
operating  restrictions  or  reduced  demand  for  our  services,  and  could  have  a  material  adverse  effect  on  our  business, 
financial condition, results of operations and cash flows.  

Apart  from  governmental  regulation,  there  are  also  increasing  financial  risks  for  companies  in  the  energy  sector  as 
shareholders and bondholders currently invested in energy companies may elect in the future to shift some or all of their 
investments  toward  non-fossil  fuel  energy  sources.  In  recent  years  there  have  been  increased  efforts  to  encourage  the 
consideration of ESG practices of companies in making investment decisions and, as a result, investment banks and asset 
managers based both domestically and internationally have announced that they are adopting climate change guidelines 
for  their  banking  and  investing  activities.  Institutional  lenders  who  provide  financing  to  energy  companies  such  as 
ourselves  have  become  more  attentive  to  sustainable  lending  practices,  and  some  may  elect  not  to  provide  traditional 
energy producers or companies that support such producers with funding. ESG considerations may also affect others in 
the investment community, including investment advisers, sovereign wealth funds, public pension funds and other groups, 
and  may  result  in  their  divestment  of  energy-related  equities.  Limitation  of  investments  in  and  financings  for  energy 
companies could result in the restriction, delay or cancellation of infrastructure projects and energy production activities. 
This  potential  for  reduced  access  to  the  capital  and  financial  markets,  whether  impacting  our  customers  and/or  our 
company, may further adversely affect the demand for and price of our securities.  

Furthermore, at this time, there is significant uncertainty with respect to the extent to which climate change may lead to 
more extreme weather patterns, but it should be noted that some scientists have concluded that increasing concentrations 
of  greenhouse  gases  in  the Earth’s  atmosphere can  change the  climate in  a  manner that  results  in  significant  weather-
related effects, such as increased frequency and severity of storms, droughts, floods and other such events. Energy needs 
could increase or decrease as a result of extreme weather conditions depending on the duration and magnitude of any such 
climate changes. Increased energy use due to weather changes may require us to invest in order to serve increased demand. 
A decrease in energy use due to weather changes may affect our financial condition through decreased revenues. To the 
extent the frequency of extreme weather events increases, this could increase our cost of providing service. If any of these 
results occur, it could have an adverse effect on our assets and operations and cause us to incur costs in preparing for and 
responding to them.  

In sum, any legislation, regulatory programs or social pressures related to climate change could increase our costs and 
require substantial capital, compliance, operating and maintenance costs, reduce demand for our services and reduce our 
access to financial markets. Current, as well as potential future, laws and regulations that limit emissions of greenhouse 
gases or that otherwise promote the use of renewable energy over fossil fuel energy sources could increase the cost of our 
midstream services and, thereby, further reduce demand and adversely affect the company’s sales volumes, revenues and 
margins. 

Increased environmental, social and governance scrutiny and changing expectations from stakeholders may impose 
additional costs or additional risks. 

In recent years, increasing attention has been given to corporate activities related to ESG matters. A number of advocacy 
groups, both domestically and internationally, have campaigned for governmental and private action to promote change at 
public companies related to ESG matters, including increasing attention and demands for action related to climate change, 
promoting the use of substitutes to fossil fuel products and encouraging the divestment of companies in the fossil fuel 
industry. Companies which do not adapt to or comply with expectations and standards on ESG matters, as they continue 
to evolve, or which are perceived to have not responded appropriately to the growing concern for ESG issues, regardless 
of whether there is a legal requirement to do so, may suffer from reputational damage and the business, financial condition 
and/or stock price of such a company could be materially and adversely affected.

Our operations, projects and growth opportunities require us to have strong relationships with various key stakeholders, 
including our shareholders, employees, suppliers, customers, local communities and others. We may face pressures from 
stakeholders, many of whom are increasingly focused on climate change, to prioritize sustainable energy practices, reduce 
our carbon footprint and promote sustainability while at the same time remaining a successfully operating public company. 
If we do not successfully manage expectations across these varied stakeholder interests, it could erode our stakeholder 
trust and thereby affect our brand and reputation. Such erosion of confidence could negatively impact our business through 
decreased demand and growth opportunities, delays in projects, increased legal action and regulatory oversight, adverse 
press coverage and other adverse public statements, difficulty hiring and retaining top talent, difficulty obtaining necessary 
approvals and permits from governments and regulatory agencies on a timely basis and on acceptable terms, and difficulty 
securing investors and access to capital. The occurrence of any of the foregoing could have a material adverse effect on 
our business and financial condition.

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  Financial  Statements,  the notes  thereto, and the  other  financial  information  appearing  elsewhere  in  this  2020 
Form 10-K. The following discussion includes forward-looking statements that involve certain risks and uncertainties. See 
“Forward-Looking Statements” and Part I Item 1A “Risk Factors” in this 2020 Form 10-K. 

Overview 

We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We are the leading 
provider of natural gas compression services to customers in the oil and natural gas industry throughout the U.S. and a 
leading supplier of aftermarket services to customers that own compression equipment in the U.S. Our business supports 
a must-run service that is essential to the production, processing, transportation and storage of natural gas. Our geographic 
diversity, technically experienced personnel and large fleet of natural gas compression equipment enable us to provide 
reliable contract operations services to our customers. 

We operate in two business segments: 

•(cid:1) Contract  Operations. Our  contract  operations  business  is  comprised  of  our  owned  fleet  of  natural  gas 

compression equipment that we use to provide operations services to our customers. 

•(cid:1) Aftermarket  Services. Our  aftermarket  services  business  provides  a  full  range  of  services  to  support  the 
compression  needs  of  our  customers that  own  compression  equipment including  operations,  maintenance, 
overhaul and reconfiguration services and sales of parts and components.

Trends and Outlook

The key driver of our business is the production of U.S. natural gas and crude oil. Approximately 75% of our operating 
fleet is deployed for midstream natural gas gathering and wellhead applications, with the remaining fleet being used in gas 
lift  applications  to  enhance  crude  oil  production.  Changes  in  natural  gas  and  crude  oil  production  spending  therefore 
typically result in changes in demand for our services. 

Spending  on  natural  gas  and  crude  oil  exploration  and  production  typically  declines  when  there  is  a  significant  and 
prolonged reduction in natural gas and crude oil prices or significant instability in energy markets and increases during 
periods of rising prices and market stability. As our business is so closely aligned with production and is typically less 
directly impacted by commodity prices, we are not exposed to the volatility often faced in shorter-cycle oil field service 
businesses.

COVID-19 Pandemic 

In the first quarter of 2020, the COVID-19 pandemic caused a deterioration in global macroeconomic conditions, including 
a collapse in the demand for natural gas and crude oil coupled with an oversupply of crude oil, which led to substantial 
spending cuts by our customers and a decline in natural gas and crude oil production. This global response to the pandemic 
has  adversely  impacted  our  market  capitalization,  revenue  and  cash  flows.  Though  demand  has  shown  modest 
improvement since the lows reached in the second quarter as economies started to reopen, additional surges of the disease 
are currently underway globally and much uncertainty still exists surrounding the magnitude and duration of the pandemic 
and resulting economic downturn. Similarly, the duration of the decreased spending and activity levels of our customers 
and the timing of their full impact on production remain difficult to predict. 

The impact of the COVID-19 pandemic on our 2020 results is primarily visible in the $99.8 million non-cash impairment 
of our goodwill and the impairment’s resulting $22.6 million tax benefit. Horsepower, utilization and revenue experienced 
declines beginning in the second quarter as compared to 2019 and are expected to remain at lower levels into 2021 in both 
our  contract  operations  and  aftermarket  services  businesses.  Long-lived  and  other  asset  impairment  and  restructuring 
charges  have also  been  significantly impacted.  See  “Financial Results  of  Operations”  below  and  Note  9  (“Goodwill”), 
Note 18 (“Long-Lived and Other Asset Impairment”), Note 19 (“Restructuring Charges”) and Note 20 (“Income Taxes”) 
to our Financial Statements for further discussion. 

In recent years, prior to the COVID-19 pandemic, increased global demand for U.S. natural gas and crude oil production 
had  contributed  to  increased  production  for  both  resources  and  record  U.S.  natural  gas  production  in  2018  and  2019. 
Production  fell  sharply  in  the  second  quarter  of  2020,  however,  as  a  result  of  the  global  response  to  the  COVID-19 
pandemic. According to the EIA, average U.S. dry natural gas and crude oil production in 2020, 2019 and 2018 were as 
follows: 

Year Ended December 31,
2019

2020

2018

Average dry natural gas production (Bcf/d)
Average crude oil production (MMb/d) 

91.3
 11.3    

92.0
 12.2   

83.8
 11.0 

The increases in production in 2018 and 2019 resulted in strong demand for our compression services in those years and 
into  the  first  quarter  of  2020.  Additionally,  we  increased  our  investment  in  new  fleet  units  in  2019  and  2018  to  take 
advantage of improved market conditions. As a result of this increased demand and investment, our contract operations 
revenue and average operating horsepower increased 15% and 10%, respectively, in 2019 compared to 2018. In 2020, 
however,  the  decrease  in  demand  and  production  brought  on  by  the  COVID-19  pandemic  drove  revenue  and  average 
operating horsepower back down to below 2019 levels.

Outlook 

The EIA forecasts the following year-over-year changes in its February 2021 Short-Term Energy Outlook report: 

U.S. dry natural gas production 
U.S. crude oil production 
U.S. natural gas domestic consumption 
Liquefied natural gas exports 

Increase (Decrease) 
2021

2022 

 (1) %    
 (3) %    
 (2) %   
 30 %    

 1 % 
 5 % 
 (1) % 
 9 % 

Overall, U.S. natural gas and crude oil production is expected to show a modest decline in 2021 as producers limit drilling 
and  completion  activity  to  achieve  maintenance  levels  of  production  and  cash  flows  in  the  course  of  the  COVID-19 
pandemic. Accordingly, we anticipate demand for our compression services to also decrease, though with a potential for 
improved conditions later in 2021 and into 2022. 

Long  term,  the  EIA expects  dry natural  gas  production to  increase  7% and  12% through  2025 and  2030,  respectively. 
Natural gas provides an affordable and reliable solution that we believe will play a prominent role in a cleaner energy mix, 
even as energy generation from renewables increases. We believe that the U.S. natural gas compression services industry 
continues to have growth potential over time due to, among other things, increased natural gas production in the U.S. from 
unconventional sources, aging producing natural gas fields that will require more compression to continue producing the 
same volume of natural gas and expected increased demand for natural gas in the U.S. for power generation, industrial 
uses and exports, including liquefied natural gas exports and exports of natural gas via pipeline to Mexico. We expect that 
such an increase in demand for U.S. natural gas will in turn lead to continued strong demand for compression services. 

In our aftermarket services business, though activity levels decreased in 2020 and 2019 as customers deferred maintenance 
activities, the base of owned compression in the U.S. has increased over the past several years, which we believe will help 
sustain our aftermarket services business over the long term. 

Key Challenges and Uncertainties 

In addition to general market conditions in the oil and gas industry and competition in the natural gas compression industry, 
we believe the following represent the key challenges and uncertainties we will face in the future. 

Capital Requirements and the Availability of External Sources of Capital. We have funded a significant portion of our 
capital expenditures and acquisitions through borrowings under the Credit Facility and have issued additional debt such 
that we now have a substantial amount of debt, which could limit our ability to fund future planned capital expenditures. 
Current conditions could limit our ability to access the debt and equity markets to raise capital on affordable terms in 2021 
and beyond. If we are not successful in raising capital within the time period required or at all, we may not be able to fund 
these capital expenditures, which could impair our ability to grow or maintain our business. 

Cost  Management. In  anticipation  of  lower  customer  activity  levels  in  response  to  the  COVID-19  pandemic,  we 
implemented a plan in the second quarter of 2020 to reduce our annual operating, corporate and capital costs by between 
$75 million and $85 million. 

In addition, in order to improve our operations, in late 2018 we began a process and technology transformation project that 
will,  among  other  things,  upgrade  or  replace  our  existing  ERP,  supply  chain  and  inventory  management  systems  and 
expand  the  remote  monitoring  capabilities  of  our  compression  fleet.  We  believe  these  improvements  will  reduce  our 
operating costs and increase our uptime, and we anticipate that the project will continue to require significant resources 
and result in increased SG&A expense and capital expenditures for the implementation of new technologies in 2021.

Table of Contents

Cost management continues to be challenging and there is no guarantee that our efforts will result in a reduction in our 
operating expenses. Natural gas production growth and resulting demand for our services, once resumed, could also cause 
us to experience increased operating expenses as we hire employees and incur additional expenses needed to support the 
rebound in market demand. 

Labor. We believe that our ability to hire, train and retain qualified personnel will continue to be important. Although we 
have been able to historically satisfy our personnel needs, retaining employees in our industry continues to be a challenge. 
Our ability to grow and to continue our current level of service to our customers will depend in part on our success in 
hiring,  training  and  retaining  our  employees,  including  those  employees  impacted  by  our  headcount  reduction  and 
furloughs through the course of the COVID-19 pandemic. 

Later-Cycle Market Participant. Compression service providers have traditionally been a later-cycle participant as energy 
markets fluctuate. As such, we anticipate that any significant change in the demand for our contract operations services 
will generally lag a change in drilling activity. Increased natural gas and crude oil production in 2018 and 2019 contributed 
to increased new orders for our compression services during those years and into the first quarter of 2020, the revenue 
gains from which were realized in 2019 and the first quarter of 2020. In the second quarter of 2020, however, customer 
demand dropped sharply in response to the COVID-19 pandemic, and the associated decrease in our revenue occurred 
almost immediately. 

Dry natural gas production, one of the key drivers of our business, increased 12% in 2018 and 10% in 2019 before falling 
1% in 2020, and is expected to increase 7% in 2021 through 2025. We believe that, similar to the rapid drops in customer 
demand and associated revenue experienced this year, our revenue will increase concurrently with a pickup in customer 
demand as the COVID-19 pandemic runs its course. Long term, we expect to return to the more traditional cycle in which 
production growth increases demand for compression services, which results in increases in revenue and gross margin, 
though on a lag of several quarters or more. 

Customer  deferrals.  Our  aftermarket  services  revenue  decreased  in  2020  and  2019  as  customers  deferred  near-term 
maintenance activities. We believe the large installed base of owned compression supports the long-term fundamentals of 
the  aftermarket  services  business:  however,  the  timing  of  a  recovery  is  difficult  to  predict,  particularly  in  light  of  the 
economic downturn caused by the COVID-19 pandemic. In the meantime, we remain focused on cost management and 
the higher margin business within our aftermarket services operations. 

Increasing  customer  focus  on  free  cash  flow.  Prior  to  the  COVID-19  pandemic,  many  of  our  customers  had  begun 
transitioning their business model to focus on sustainable free cash flow generation rather than growth, and the COVID-
19 pandemic has further fueled this change in focus. We expect this transition to have a positive impact on the industry in 
the long term, as we anticipate the change will reduce volatility through cycles and improve the financial strength of our 
customers. In the near term, however, we can expect this transition, combined with the impact of the COVID-19 pandemic, 
to  result  in  a  deceleration in  the  natural gas  production  growth rate,  to  which  demand for  our  products  and  services is 
closely aligned.

Non-GAAP Financial Measures 

Management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant 
factors in assessing our operating results and profitability and include the non-GAAP financial measure of gross margin. 

We  define  gross  margin as total  revenue less cost  of  sales (excluding depreciation and amortization).  Gross  margin  is 
included as a supplemental disclosure because it is a primary measure used by our management to evaluate the results of 
revenue and cost of sales (excluding depreciation and amortization), which are key components of our operations. We 
believe gross margin is important because it focuses on the current operating performance of our operations and excludes 
the impact of the prior historical costs of the assets acquired or constructed that are utilized in those operations, the indirect 
costs  associated  with  our  SG&A  activities,  our  financing  methods  and  income  taxes.  In  addition,  depreciation  and 
amortization may not accurately reflect the costs required to maintain and replenish the operational usage of our assets and 
therefore  may  not  portray  the  costs  of  current  operating  activity.  As  an  indicator  of  our  operating  performance,  gross 
margin should not be considered an alternative to, or more meaningful than, net income (loss) as determined in accordance 
with GAAP. Our gross margin may not be comparable to a similarly-titled measure of other entities because other entities 
may not calculate gross margin in the same manner. 

Gross margin has certain material limitations associated with its use as compared to net income (loss). These limitations 
are primarily due to the exclusion of SG&A, depreciation and amortization, impairments, restatement and other charges, 
restructuring charges, interest expense, debt extinguishment loss, transaction-related costs, (gain) loss on sale of assets, 
net, other (income) loss, net, provision for (benefit from) income taxes and loss from discontinued operations, net of tax. 
Because we intend to finance a portion of our operations through borrowings, interest expense is a necessary element of 
our  costs  and  our  ability  to  generate  revenue.  Additionally,  because  we  use  capital  assets,  depreciation  expense  is  a 
necessary element of our costs and our ability to generate revenue and SG&A is necessary to support our operations and 
required  corporate  activities.  To  compensate  for  these  limitations,  management  uses  this  non-GAAP  measure  as  a 
supplemental measure to other GAAP results to provide a more complete understanding of our performance.

Financial Results of Operations: Summary of Results 

Revenue.  Revenue  was  $875.0  million,  $965.5  million  and $904.4  million  during  the years  ended  December 31, 2020, 
2019 and 2018, respectively. 

The decrease in revenue during the year ended December 31, 2020 compared to the year ended December 31, 2019 was 
due  to  decreases  in  revenue  from  our contract operations  and aftermarket  services businesses. The increase  in  revenue 
during  the  year  ended  December  31,  2019  compared  to  the  year  ended  December  31,  2018  was  due  to  an  increase  in 
revenue  from our  contract  operations  business,  partially  offset by a decrease  in  revenue  from our aftermarket  services 
business. 

See “Contract Operations” and “Aftermarket Services” below for further details. 

Net income (loss) attributable to Archrock stockholders. We had a net loss attributable to Archrock stockholders of $68.4 
million and net income attributable to Archrock stockholders of $97.3 million and $21.1 million during the years ended 
December 31, 2020, 2019 and 2018, respectively. 

The change from net income to net loss attributable to Archrock stockholders during the year ended December 31, 2020 
compared to the year ended December 31, 2019 was primarily driven by goodwill impairment of $99.8 million, increases 
in long-lived and other asset impairment, restructuring charges and depreciation and amortization and decreases in benefit 
from income taxes, gain on sale of assets, net and gross margin from our aftermarket services business, partially offset by 
decreases in SG&A and transaction-related costs and an increase in gross margin from our contract operations business. 

The increase in net income attributable to Archrock stockholders during the year ended December 31, 2019 compared to 
the  year  ended  December 31,  2018  was  primarily  driven  by  an increase  in  gross  margin  from  our  contract  operations 
business, the change in provision for (benefit from) income taxes, an increase in gain on sale of assets, net and the decrease 
in net income attributable to noncontrolling interest, partially offset by increases in long-lived and other asset impairment, 
SG&A, depreciation and amortization and interest expense.

Increase   
      (Decrease)  

Revenue  decreased  primarily  due  to  returns  of  horsepower  amidst  the  market  downturn,  the  strategic  disposition  of 
horsepower in 2019 and 2020 and a decrease in revenues associated with reduced mobilization activity. These decreases 
in revenue were partially offset by a $43.5 million increase in revenue attributable to the horsepower acquired in the Elite 
Acquisition in August 2019. 

Gross margin increased due to the decrease in cost of sales, which was partially offset by the decrease in revenue discussed 
above.  The  decrease  in  cost  of  sales  was  primarily  driven  by  decreases  in  costs  to  mobilize  compression  packages, 
maintenance expense and  lube  oil expense, all  of  which  were  chiefly  driven  by  the  decreases  in operating  horsepower 
mentioned above. In addition, there was a decrease in sales and use tax as the result of audit settlements in 2020. These 
decreases were partially offset by increases in maintenance expense and lube oil expense associated with the horsepower 
acquired in the Elite Acquisition.

Increase   
      (Decrease)  

The decrease in revenue was due to decreases in service activities and parts sales, which were primarily driven by reduced 
customer demand and customer deferral of maintenance activities. Gross margin decreased due to this decrease in revenue, 
but benefited from a decrease in cost of sales, which was driven by the same decrease in service activities and parts sales.

Selling, general and administrative. The decrease in SG&A was primarily due to a $6.2 million decrease in sales and use 
tax that was mainly driven by audit settlements, a $2.1 million decrease in professional expenses, a $2.1 million decrease 
in compensation and benefits and a $1.9 million decrease in employee travel and meeting expenses. These decreases were 
partially offset by a $1.0 million increase in bad debt expense. 

Depreciation  and  amortization.  The  increase  in  depreciation  and  amortization  was  primarily  due  to  an  increase  in 
depreciation expense associated with fixed asset additions during 2019, including the fixed assets acquired in the Elite 
Acquisition, and the first half of 2020, partially offset by a decrease in depreciation expense resulting from assets reaching 
the  end  of  their  depreciable  lives  as  well  as  the  impact  of  asset  impairments  in  2019  and  the  first  half  of  2020  and 
compression asset sales during 2019. 

Long-lived and other asset impairment. Each quarter, we review the future deployment of our idle compressors for units 
that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. In addition, 
we evaluate for impairment idle units that have been culled from our compression fleet in prior years and are available for 
sale.  See  Note 18  (“Long-Lived  and  Other  Asset  Impairment”)  to  our  Financial  Statements  for  further  details.  The 
following table presents the results of our compression fleet impairment review, as recorded in our contract operations 
segment (dollars in thousands):

Also during the year ended December 31, 2020, $1.7 million of capitalized implementation and unamortized prepaid costs 
related to the mobile workforce component of our multi-year process and technology transformation project was impaired. 
See Note 12 (“Hosting Arrangements”) to our Financial Statements for further details. 

Goodwill impairment. During the year ended December 31, 2020, we recorded $99.8 million of goodwill impairment due 
to  the  decline  in  the  fair  value  of  our  contract  operations  reporting  unit.  See  Note  9  (“Goodwill”)  to  our  Financial 
Statements for further details. 

Restructuring charges. We recorded $8.5 million of severance and property disposal costs related to restructuring activities 
during the year ended December 31, 2020. See Note 19 (“Restructuring Charges”) to our Financial Statements for further 
details.

Interest expense. The increase in interest expense was primarily due to an increase in the average outstanding balance of 
long-term debt, partially offset by a decrease in the weighted average effective interest rate. 

Debt extinguishment loss. We recorded a debt extinguishment loss of $4.0 million during the year ended December 31, 
2020 as a result of the redemption of the 2022 Notes. We recorded a debt extinguishment loss of $3.7 million during the 
year ended December 31, 2019 as a result of the redemption of the 2021 Notes. See Note 14 (“Long-Term Debt”) to our 
Financial Statements for further details.

Transaction-related costs. We incurred $8.2 million of financial advisory, legal and other professional fees during the year 
ended December 31, 2019 related primarily to the Elite Acquisition. 

Gain on sale of assets, net. Our net gain on the sale of assets during the year ended December 31, 2020 was primarily due 
to a $9.3 million gain on the July 2020 Disposition, a $3.2 million gain on the March 2020 Disposition, which included a 
$4.8 million gain on the compression assets sold, and gains of $3.7 million on sales of transportation and shop equipment. 
These gains were offset by a $5.1 million loss on other compression assets sold during 2020. 

Our net gain on the sale of assets during the year ended December 31, 2019 was primarily due to a $6.6 million gain on 
the  Harvest  Sale,  gains  of  $7.9  million  on  other  2019  compression  asset  sales  and  gains  of  $1.6  million  on  sales  of 
transportation and shop equipment.  

Other  income,  net. The  increase  in  other income, net  was primarily  due to a  $0.7  million  decrease  in  indemnification 
expense incurred pursuant to our tax matters agreement with Exterran Corporation.

      (Decrease)  

The increase in revenue during the year ended December 31, 2019 compared to the year ended December 31, 2018 was 
primarily due to an increase in contract operations rates driven by an increase in customer demand, an increase in average 
operating horsepower (excluding the horsepower acquired in the Elite Acquisition) and $33.2 million of revenue associated 
with the compression assets acquired in the Elite Acquisition.

Gross  margin  increased  during  the year  ended  December 31,  2019  compared  to  the year  ended  December 31,  2018 
primarily due to the increase in revenue mentioned above partially offset by the increase in cost of sales. The increase in 
cost of sales was primarily driven by increases in maintenance, freight and lube oil expense associated with the increase 
in average operating horsepower and the horsepower acquired in the Elite Acquisition. These increases in cost of sales 
were partially offset by a decrease in cost associated with the start-up of compression packages, as the majority of the 
increase in average operating horsepower was comprised of newly-built compressors. 

Gross margin percentage increased during the year ended December 31, 2019 compared to the year ended December 31,

Gross margin decreased during the year ended December 31, 2019 compared to the year ended December 31, 2018 due to 
the decrease in revenue mentioned above, partially offset by a smaller decrease in cost of sales. The decrease in cost of

Selling, general and administrative. The increase in SG&A expense during the year ended December 31, 2019 compared 
to the year ended December 31, 2018 was primarily due to a $9.2 million increase in sales and use tax expense primarily 
resulting  from  the  settlement  of audits in 2018, a  $4.1  million increase in costs  related to our  process  and  technology 
transformation project and a $2.7 million increase in compensation and benefits. 

Depreciation  and  amortization. The  increase  in  depreciation  and  amortization  expense  during  the year  ended 
December 31,  2019  compared  to  the year  ended  December 31, 2018  was  primarily  due  to  an  increase  in  depreciation 
expense associated with fixed asset additions, which was partially offset by a decrease in expense from assets reaching the 
end of their useful lives, asset retirements and the impact of asset impairments during 2018 and 2019. The increase in 
depreciation  expense  was  partially  offset  by  a  decrease  in  amortization  expense  that  primarily  resulted  from  certain 
intangible assets reaching the end of their useful lives, partially offset by amortization expense related to the intangible 
assets acquired in the Elite Acquisition.

Restatement and other charges. During the years ended December 31, 2019 and 2018, we recorded expense of $0.4 million 
and $1.3 million, respectively, for our share of professional and legal fees related to the restatement of prior period financial 
statements and disclosures and related matters. We recorded $1.3 million for the expected recovery of shared fees incurred 
during the year ended December 31, 2018. 

Interest expense. The increase in interest expense during the year ended December 31, 2019 compared to the year ended 
December 31, 2018 was primarily due to an increase in the average outstanding balance of long-term debt, partially offset 
by a decrease in the weighted average effective interest rate. 

Debt extinguishment loss. We recorded a debt extinguishment loss of $3.7 million during the year ended December 31, 
2019 as a  result  of  the  redemption  of the  2021  Notes. We recorded  a  debt  extinguishment loss  of  $2.5  million  during 
the year ended December 31, 2018 as a result of the termination of the Former Credit Facility. See Note 14 (“Long-Term 
Debt”) to our Financial Statements for further details. 

Transaction-related costs. We incurred $8.2 million and $10.2 million of financial advisory, legal and other professional 
fees during the years ended December 31, 2019 and 2018, respectively. The $8.2 million of fees incurred during the year 
ended December 31, 2019 related primarily to the Elite Acquisition. The $10.2 million of fees incurred during the year 
ended  December 31, 2018 related to the  Merger.  See  Note 4  (“Business Transactions”) and  Note 16  (“Equity”) to  our 
Financial Statements for further details of these transactions.

Gain on sale of assets, net. The increase in gain on sale of assets, net was primarily due to a $6.6 million gain related to 
the  Harvest  Sale  during  the year  ended  December 31,  2019  and  a  $3.2  million  increase  in  gains  recognized  on  other 
compression equipment sales during the year ended December 31, 2019 compared to the year ended December 31, 2018. 
See Note 4 (“Business Transactions”) for further details of the Harvest Sale. 

Other income, net. The increase in other income, net during the year ended December 31, 2019 compared to the year ended 
December 31, 2018 was primarily due to a $0.9 million decrease in indemnification expense incurred pursuant to our tax 
matters agreement with Exterran Corporation and income of $0.3 million related to equipment damaged at a customer site 
during 2019, partially offset by $0.5 million in indemnification income earned pursuant to that same tax matters agreement 
during 2018 and a $0.3 million decrease in interest income earned related to tax refunds and settlements.

Net income attributable to noncontrolling interest was the portion of the Partnership’s earnings that were applicable to the 
Partnership’s publicly-held common unitholder interest through the completion of the Merger. Immediately prior to the 
Merger, public unitholders held a 57% ownership interest in the Partnership. Subsequent to the Merger, the Partnership is 
a wholly-owned subsidiary. See Note 16 (“Equity”) to our Financial Statements for further details of the Merger. 

Liquidity and Capital Resources 

Capital Requirements 

Our contract operations business is capital intensive, requiring significant investment to maintain and upgrade existing 
operations.  Our  capital  spending  is  primarily  dependent  on  the  demand  for  our  contract  operations  services  and  the 
availability  of  the  type  of  compression  equipment  required  for  us  to  provide  those  contract  operations  services  to  our 
customers.  Our  capital  requirements  have  consisted  primarily  of,  and  we  anticipate  will  continue  to  consist  of,  the 
following: 

•(cid:1)

growth capital expenditures, which are made to expand or to replace partially or fully depreciated assets or to 
expand the operating capacity or revenue generating capabilities of existing or new assets; and 

•(cid:1) maintenance capital expenditures, which are made to maintain the existing operating capacity of our assets and 

related cash flows further extending the useful lives of the assets.

Growth Capital Expenditures 

The  majority  of  our  growth capital expenditures  are  related  to  the acquisition  cost  of  new compressors  when  our  idle 
equipment cannot be reconfigured to economically fulfill a project’s requirements and the new compressor is expected to 
generate  economic  returns  over  its  expected  useful  life  that  exceed  our  cost  of  capital.  In  addition  to  newly-acquired 
compressors, growth capital expenditures include the upgrading of major components on an existing compression package 
where the current configuration of the compression package is no longer in demand and the compressor is not likely to 
return  to  an  operating  status  without  the  capital  expenditures.  These  expenditures  substantially  modify  the  operating 
parameters of the compression package such that it can be used in applications for which it previously was not suited.  

Growth  capital  expenditures  were  $79.1  million,  $300.5  million  and  $251.6  million  during  the years  ended 
December 31, 2020, 2019 and 2018, respectively. The decrease in growth capital expenditures in 2020 compared to 2019 
was the result of a previously-planned decrease in spending in 2020, which was based on an expected deceleration in the 
growth rate of natural gas production, and a further reduction in spend in response to the decreased customer demand that 
resulted  from  the  COVID-19  pandemic.  The  increase  in  growth  capital  expenditures  in  2019  compared  to  2018  was 
primarily due to increased investment in new compression equipment as a result of increased customer demand to support 
higher U.S. natural gas production levels.

Maintenance Capital Expenditures 

Maintenance capital expenditures are related to major overhauls of significant components of a compression package, such 
as  the  engine,  compressor  and  cooler,  which  return  the  components  to  a  like-new  condition,  but  do  not  modify  the 
application for which the compression package was designed. 

Maintenance  capital  expenditures  were  $32.0  million,  $58.6  million  and  $49.7  million  during  the years  ended 
December 31, 2020, 2019 and 2018, respectively. The decrease in maintenance capital expenditures in 2020 compared to 
2019  was  the  result  of  decreased  customer  demand  amidst  the  COVID-19  pandemic  and  optimized  engine  overhaul 
practices. The increase in maintenance capital expenditures in 2019 compared to 2018 was due to an increase in scheduled 
maintenance activities in 2019 due to maintenance cycle requirements as well as the increase in horsepower as the result 
of the Elite Acquisition. 

Projected Capital Spend 

We  currently  plan  to  spend  approximately  $80  million  to  $106  million  in  capital  expenditures  during  2021,  primarily 
consisting of approximately $30 million to $50 million for growth capital expenditures and approximately $40 million to 
$45 million for maintenance capital expenditures. We anticipate decreased 2021 capital expenditures, particularly growth 
capital expenditures, as compared to 2020 due to the impact that we expect the COVID-19 pandemic will continue to have 
on customer demand.  

Financial Resources 

Overview 

Our ability to fund operations, finance capital expenditures and pay dividends depends on the levels of our operating cash 
flows and access to the capital and credit markets. Our primary sources of liquidity are cash flows generated from our 
operations  and  our  borrowing  availability  under  the  Credit  Facility.  Our  cash  flow  is  affected  by  numerous  factors 
including prices and demand for our services, oil and natural gas exploration and production spending, conditions in the 
financial  markets  and  other  factors.  Beginning  in  the  first  quarter  of 2020,  the  COVID-19  pandemic  has  caused  a 
deterioration in global macroeconomic conditions, which has significantly impacted our estimates of future revenues and 
cash flows. However, we have no near-term maturities and believe that our operating cash flows and borrowings under the 
Credit Facility will be sufficient to meet our future liquidity needs. 

We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for 
equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, 
if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. 

Revolving Credit Facilities 

Credit Facility. During the years ended December 31, 2020 and 2019, the Credit Facility had an average daily balance of 
$704.5  million  and $855.3  million,  respectively.  The  weighted  average annual  interest  rate  on  the  outstanding  balance 
under the Credit Facility, excluding the effect of interest rate swaps, was 2.7% and 4.3% at December 31, 2020 and 2019, 
respectively. As of December 31, 2020, there were $12.4 million letters of credit outstanding under the Credit Facility and 
the applicable margin on borrowings outstanding was 2.4%. 

In November 2019, we amended the Credit Facility to, among other things, extend the maturity date of the Credit Facility 
from March 30, 2022 to November 8, 2024 and change the applicable margin for borrowings under the Credit Facility 
such that (i) the applicable margin for LIBOR loans ranges from 2.00% to 2.75% and (ii) the applicable margin for base 
rate loans ranges from 1.00% to 1.75%.

In February 2018, we amended the Credit Facility to, among other things: 

•(cid:1)

•(cid:1)
•(cid:1)
•(cid:1)

increase the maximum Total Debt to EBITDA ratios, as defined in the Credit Facility agreement (see below for 
the revised ratios); 
increase the aggregate revolving commitment from $1.1 billion to $1.25 billion; 
increase the amount available for the issuance of letters of credit from $25.0 million to $50.0 million; and 
increase the basket sizes under certain covenants including covenants limiting our ability to make investments, 
incur debt, make restricted payments, incur liens and make asset dispositions. 

See Note 14 (“Long-Term Debt”) to the Financial Statements for further details of these amendments. 

Portions of the Credit Facility up to $50.0 million are available for the issuance of swing line loans. Subject to certain 
conditions, including the approval by the lenders, we are able to increase the aggregate commitments under the Credit 
Facility by up to an additional $250.0 million. The Credit Facility borrowing base consists of eligible accounts receivable, 
inventory and compressors. 

As of December 31, 2020, prior to Amendment No. 3, the following consolidated financial ratios, as defined in our Credit 
Facility agreement, were required: 

EBITDA to Interest Expense 
Senior Secured Debt to EBITDA 
Total Debt to EBITDA 

January 1 through June 30, 2020 
Thereafter (1) 

2.5 to 1.0

(1)(cid:1)

Subject to a temporary increase to 5.50 to 1.0 for any quarter during which an acquisition satisfying certain thresholds is completed and for the two 
quarters immediately following such quarter. 

As a result of the ratio requirements above, $444.1 million of the $844.6 million of undrawn capacity was available for 
additional borrowings as of December 31, 2020. 

The Credit Facility agreement contains various additional covenants including, but not limited to, mandatory prepayments 
from the net cash proceeds of certain asset transfers, restrictions on the use of proceeds from borrowings and limitations 
on our  ability to  incur additional  indebtedness, engage in  transactions  with affiliates,  merge  or consolidate,  sell assets, 
make  certain  investments  and  acquisitions,  make  loans,  grant  liens,  repurchase  equity  and  pay  distributions.  As  of 
December 31, 2020, we were in compliance with all covenants under the Credit Facility.

In February 2021, we further amended the Credit Facility to, among other things: 

•(cid:1)
•(cid:1)

reduce the aggregate revolving commitment from $1.25 billion to $750.0 million, and

Former  Credit  Facility.  In  April 2018,  in  connection  with  the  Merger,  we  terminated  the  Former  Credit  Facility  and 
borrowed on the Credit Facility to repay $63.2 million in borrowings and accrued and unpaid interest and fees outstanding. 
All commitments under the Former Credit Facility were terminated and the $15.4 million of letters of credit outstanding 
under the Former Credit Facility were converted to letters of credit under the Credit Facility. Prior to its termination, the 
Former  Credit  Facility  required  us  to  maintain  various  financial  ratios  and  other  covenants,  all  of  which  we  were  in 
compliance with through its closing. The average daily debt balance under the Former Credit Facility in 2018, through its 
closing in April 2018, was $51.7 million.

Senior Notes Transactions 

In December 2020, we completed a private offering of $300.0 million aggregate principal amount of 6.25% senior notes 
due April 2028 and received net proceeds of $309.9 million after deducting issuance costs. The net proceeds were used to 
repay borrowings outstanding under our Credit Facility. 

In April 2020, we repaid the 2022 Notes with borrowings under our Credit Facility. 

In December 2019, we completed a private offering of $500.0 million aggregate principal amount of 6.25% senior notes 
due April 2028 and received net proceeds of $491.8 million after deducting issuance costs. The net proceeds were used to 
repay borrowings outstanding under our Credit Facility. 

In April 2019, we repaid the 2021 Notes with borrowings under our Credit Facility. 

In March 2019, we completed a private offering of $500.0 million aggregate principal amount of 6.875% senior notes due 
April 2027 and  received  net proceeds  of  $491.2  million  after deducting  issuance  costs.  The  net  proceeds  were  used  to 
repay borrowings outstanding under our Credit Facility. 

See Note 14 (“Long-Term Debt”) to our Financial Statements for further details of these transactions.

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

Operating  Activities.  The  increase  in  net  cash  provided  by  operating  activities  was  primarily  due  to  decreased  cash 
outflows for cost of sales, SG&A expenses, contract costs and transaction-related costs and increased cash inflows from 
accounts receivable, partially offset by reduced cash inflows from revenue and deferred revenue and cash outflows for 
restructuring charges in 2020. 

Investing Activities. The decrease in net cash used in investing activities was primarily due to a $244.9 million decrease in 
capital expenditures, $214.0 million cash paid in the Elite Acquisition in 2019 and proceeds of $33.7 million from the 
March  2020  and  July  2020  dispositions,  partially  offset  by  a  $62.1  million  decrease  in  proceeds  from  other  sales  of 
property, plant and equipment, $30.0 million of which related to proceeds from the Harvest Sale in 2019.

Financing Activities. The change in net cash provided by (used in) financing activities was primarily due to $155.4 million 
of net repayments of long-term debt in 2020 compared to $323.5 million of net borrowings in 2019 and a $10.3 million 
increase in dividends  paid  to  Archrock  stockholders,  partially  offset  by  a  $17.2  million  decrease in  payments for debt 
issuance costs. 

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

Operating Activities. The increase in net cash provided by operating activities during the year ended December 31, 2019 
compared to the year ended December 31, 2018 was primarily due to an increase in revenue from our contract operations 
business, the receipt of cash proceeds in 2019 pursuant to a settlement of certain sales and use tax audits and decreases in 
accounts receivable and cost of sales (excluding depreciation and amortization). These cash inflows were partially offset 
by increases in cash SG&A expenses and interest paid on our long-term debt and a decrease in accounts payable and other 
liabilities. 

Investing  Activities.  The  increase  in  net  cash  used  in  investing  activities  during  the year  ended  December 31,  2019 
compared to the year ended December 31, 2018 was primarily due to $214.0 million of cash paid in the Elite Acquisition 
during the year ended December 31, 2019 and a $66.1 million increase in capital expenditures, partially offset by a $47.0 
million increase in proceeds from the sale of property, plant and equipment and other assets, including $30.0 million in 
proceeds from the Harvest Sale. 

Financing Activities. The increase in net cash provided by financing activities during the year ended December 31, 2019 
compared to the year ended December 31, 2018 was primarily due to a $214.3 million net increase in borrowings of long-
term debt and an $11.8 million decrease in distributions paid to noncontrolling partners in the Partnership. These cash 
flows were partially offset by a $20.2 million increase in dividends paid to Archrock shareholders, a $19.1 million increase 
in payments for debt issuance costs and an $18.7 million decrease in contributions from Exterran Corporation. 

Dividends 

On  January 27,  2021,  our  Board  of  Directors  declared  a  quarterly  dividend  of  $0.145  per  share  of  common  stock,  or 
approximately $22.2  million,  that  was  paid  on  February 16,  2021  to stockholders  of  record  at  the  close  of  business on 
February 8, 2021.  Any future determinations  to pay cash dividends to  our stockholders  will be at the discretion  of  our 
Board  of  Directors  and  will  be  dependent  upon  our  financial  condition,  results  of  operations,  and  credit  and  loan 
agreements in effect at that time and other factors deemed relevant by our Board of Directors.

At December 31, 2020, $18.9 million of unrecognized tax benefits (including discontinued operations) have been recorded 
as liabilities in accordance with the accounting standard for income taxes related to uncertain tax positions and we are 
uncertain as to if or when such amounts may be settled. Related to these unrecognized tax benefits, we have also recorded 
a liability for potential penalties and interest (including discontinued operations) of $2.1 million. 

Off-Balance Sheet Arrangements 

For  information  on  our  obligations  with  respect  to  letters  of  credit  and  performance  bonds,  see  Note 14 (“Long-Term 
Debt”) and Note 26 (“Commitments and Contingencies”), respectively, to our Financial Statements. 

Critical Accounting Estimates 

This discussion and analysis of our financial condition and results of operations is based upon our Financial Statements, 
which have been prepared in accordance with GAAP. The preparation of our Financial Statements requires us to make 
estimates  and  judgments  that  affect  the  reported  amounts  of  assets,  liabilities,  expenses  and  related  disclosures  of 
contingent assets and liabilities. We evaluate our estimates  and accounting policies  on an  ongoing  basis  and  base  our 
estimates  on  historical experience and  other  assumptions that  we  believe  are  reasonable  under  the circumstances. The 
results of this process form the basis of our judgments about the carrying values of assets and liabilities that are not readily 
apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and 
these  differences  can  be  material  to  our  financial  condition,  results  of  operations  and  cash  flows.  We  describe  our 
significant accounting policies more fully in Note 2 (“Basis of Presentation and Significant Accounting Policies”) to our 
Financial Statements. 

Allowance for Credit Losses 

Outstanding accounts receivable are reviewed regularly for non-payment indicators and allowances for credit losses are 
recorded based on management’s estimate of collectibility at each balance sheet date. We measure expected credit losses 
on a collective (pool) basis when similar risk characteristics exist. If a customer does not share similar risk characteristics 
with other customers, we evaluate the customer’s outstanding trade receivables for expected credit losses on an individual 
basis.  Each  reporting  period,  we  reassess  our  customers’  risk  profiles  and  determine  the  appropriate  asset  pool 
classification, or perform individual assessments of expected credit losses, based on the customers’ risk characteristics at 
the  reporting  date. Judgment  is  used  to  determine the  expected credit  loss  for  customers that  do not  share  similar risk 
characteristics with other customers, based on customer specific items such as legal proceedings, past experience with the 
customer and/or ongoing customer negotiations. 

During the years ended December 31, 2020, 2019 and 2018, we recorded bad debt expense of $3.5 million, $2.6 million 
and $1.7 million, respectively. A five percent change in bad debt expense would have impacted loss before income taxes 
by $0.2 million during the year ended December 31, 2020. 

Inventory 

Inventory is a significant component of current assets and is stated at the lower of cost and net realizable value using the 
average cost method. This requires us to regularly review inventory quantities on hand and compare them to estimates of 
future product demand and market conditions. These estimates and forecasts inherently include uncertainties and require 
us  to  make  judgments  regarding  potential  outcomes.  During  the years  ended  December 31, 2020,  2019  and  2018,  we 
recorded write-downs to inventory of $1.3 million, $0.9 million and $1.6 million, respectively, for inventory considered 
to be excess, obsolete or carried at an amount in excess of net realizable value. Significant or unanticipated changes to our 
estimates and forecasts could require additional write-downs in a future period. Given the nature of these evaluations and 
their application to specific inventories, it is not possible to reasonably quantify the impact of changes in these estimates 
and forecasts. 

50 

Table of Contents

Depreciation 

Property, plant and equipment are carried at cost. Depreciation is computed on a straight-line basis using useful lives and 
salvage  values  that  are  estimated  based  on  assumptions  and  judgments  that  reflect  both  historical  experience  and 
expectations  regarding  future  use  of  our  assets.  The  use  of  different  assumptions  and  judgments  in  the  calculation  of 
depreciation, especially those involving useful lives, would likely result in significantly different net book values of our 
assets and results of operations. 

Fair Value Estimates 

Impairment Assessments of Property, Plant and Equipment and Identifiable Intangible Assets 

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, 
for impairment whenever events or changes in circumstances, including the removal of compressors from our active fleet, 
indicate that the carrying amount of an asset may not be recoverable. An impairment loss may exist when the estimated 
undiscounted cash flows expected from the use of the asset and its eventual disposition are less than its carrying amount. 
Determining whether the carrying amount of an asset is recoverable requires us to make judgments regarding long-term 
forecasts of future revenue and costs related to the asset subject to review. These forecasts are uncertain as they require 
significant assumptions about future market conditions. Significant and unanticipated changes to these assumptions could 
require a provision for impairment in a future period. Given the nature of these evaluations and their application to specific 
assets and specific times, it is not possible to reasonably quantify the impact of changes in these assumptions. 

Impairment Assessment of Goodwill 

We review the carrying amount of our goodwill in the fourth quarter of every year, or whenever indicators of potential 
impairment exist, to determine if the carrying amount of a reporting unit exceeds its fair value, including the applicable 
goodwill. We  perform a qualitative assessment  to  determine  whether  it  is  more  likely  than  not  that  the  fair  value  of  a 
reporting unit is impaired. If the fair value is more likely than not impaired, we perform a quantitative impairment test to 
identify impairment and measure the amount of impairment loss to be recognized, if any. 

Our  qualitative  assessment  includes  consideration  of  various  events  and  circumstances  and  their  potential  impact  to  a 
reporting  unit’s  fair  value,  including  macroeconomic  and  industry  conditions  such  as  a  deterioration  in  our  operating 
environment and limitations on access to capital and other developments in the equity and credit markets, cost factors that 
could have a negative effect on earnings and cash flows, relevant entity-specific and reporting unit-specific events and 
overall financial performance such as declining earnings or cash flows or a sustained decrease in share price. If indicated, 
a quantitative impairment test would compare the carrying amount of our reporting units to their fair value, and any excess 
of carrying amount over fair value would be recorded as an impairment loss. The fair value calculation would require us 
to make significant estimates to determine future cash flows, including future revenues, costs and capital requirements and 
the appropriate risk-adjusted discount rate by which to discount the estimated future cash flows. 

Our goodwill was allocated to our contract operations reporting unit. In the first quarter of 2020, the global response to 
the COVID-19 pandemic significantly impacted our market capitalization and estimates of future revenues and cash flows, 
which triggered  the  need  to perform a  quantitative  test  of  the  fair  value of  our  contract  operations  reporting  unit as  of 
March  31,  2020.  The  quantitative  test  determined  that  the  carrying  amount  of  our  contract  operations  reporting  unit 
exceeded its fair value and we recorded a full impairment loss on goodwill in the first quarter as a result. 

Acquisitions 

We account for business combinations using the acquisition method which requires assets acquired and liabilities assumed 
to be recorded at their fair value on the acquisition date. The excess of the consideration transferred over those fair values 
is  recorded  as  goodwill.  Significant  judgment  is  used  in  determining  the  individual  fair  values  of  acquired  assets  and 
liabilities. We use all available information to make these fair value determinations and, for certain acquisitions, engage 
third-party consultants for valuation assistance. 

51 

Table of Contents

For the Elite Acquisition, we used the cost approach to value the acquired property, plant and equipment, whereby we 
estimated the replacement cost of the assets by evaluating recent purchases of similar assets or published data, and then 
adjusted  replacement  cost  for  physical  deterioration  and  functional  and  economic  obsolescence,  as  applicable.  We 
estimated the fair value of the acquired identifiable intangible assets using the multi-period excess earnings method, which 
is  a  specific  application  of  the  discounted  cash  flow  method,  an  income  approach,  whereby  we  estimated  and  then 
discounted the future cash flows of the intangible asset by adjusting overall business revenue for attrition, obsolescence, 
cost  of  sales,  operating  expenses,  taxes  and  the  required  returns  attributable  to  other  contributory  assets  acquired. 
Significant estimates made in arriving at expected future cash flows included our expected customer attrition rate and the 
amount of earnings attributable to the assets. To discount the estimated future cash flows, we utilized a discount rate that 
was at a premium to our weighted average cost of capital to reflect the less liquid nature of the customer relationships 
relative to the tangible assets acquired. 

The estimates used in determining the fair value of the asset and liabilities acquired in the Elite Acquisition are based on 
assumptions believed to be reasonable but which are inherently uncertain. Accordingly, actual results may differ materially 
from the projected results used to determine fair value. See Note 4 (“Business Transactions”) to our Financial Statements 
for further details of the Elite Acquisition. 

Income Taxes 

Our income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s 
best assessment of estimated current and future taxes to be paid. We operate in the U.S. only and, as a result, are subject 
to income taxes in the U.S. only. Significant judgments and estimates are required in determining consolidated income tax 
expense. 

Deferred income taxes arise from temporary differences between the financial statements and the tax basis of assets and 
liabilities.  In  evaluating  our  ability  to  recover  our  deferred  tax  assets,  we  consider  all  available  positive  and  negative 
evidence including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies 
and results of recent operations. In projecting future taxable income, we begin with historical results adjusted for the results 
of discontinued operations and changes in accounting policies and incorporate assumptions, including the amount of future 
U.S. federal and state pretax operating income, the reversal of temporary differences and the implementation of feasible 
and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable 
income and are  consistent  with the  plans and estimates  we use  to  manage  the  underlying businesses.  In  evaluating the 
objective evidence that historical results provide, we consider three years of cumulative income (loss) before income taxes. 

Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management is 
not aware of any such changes that would have a material effect on our financial position, results of operations or cash 
flows. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and 
regulations in various state and local jurisdictions.

The accounting standard for income taxes provides that a tax benefit from an uncertain tax position may be recognized 
when it is more likely than not that the position will be sustained upon examination, including resolutions of any related 
appeals or litigation processes, on the basis of the technical merits. We adjust these liabilities when our judgment changes 
as a  result of the evaluation of new  information  not  previously available.  Because  of the  complexity  of  some  of  these 
uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the 
liabilities. Such differences are reflected as increases or decreases to income tax expense in the period in which the new 
information becomes available.

Contingencies and Litigation 

Insurance 

Our  insurance  coverage  includes  property  damage,  general  liability  and  commercial  automobile  liability  and  other 
coverage  we  believe  is  appropriate.  Additionally,  we  are  self-insured  for  property  damage  to  our  offshore  assets  and 
substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-
incident  deductibles  we  absorb  under our  insurance  arrangements  for these  risks. Losses  up  to  deductible amounts are 
estimated  and  accrued  based  upon  known  facts,  historical  trends  and  industry  averages.  We  review  these  estimates 
quarterly and believe such accruals to be adequate. However, insurance liabilities are difficult to estimate due to unknown 
factors, including the severity of an injury, the determination of our liability in proportion to other parties, the timeliness 
of reporting of occurrences, ongoing treatment or loss mitigation, general trends in litigation recovery outcomes and the 
effectiveness of safety and risk management programs. If our actual experience differs from the assumptions and estimates 
used for recording the liabilities, adjustments may be required and would be recorded in the period in which the difference 
becomes known. At December 31, 2020 and 2019, we had $3.4 million and $3.0 million, respectively, in insurance claim 
reserves on our consolidated balance sheets.

Litigation and Claims 

In the ordinary course of business, we are involved in various pending or threatened legal actions. While we are unable to 
predict the ultimate outcome of these actions, the accounting standard for contingencies requires management to make 
judgments about future events that are inherently uncertain. We are required to record a loss during any period in which 
we believe a contingency is probable and can be reasonably estimated. In making determinations of likely outcomes of 
pending or threatened legal matters, we consider the evaluation of counsel knowledgeable about each matter. 

The impact of an uncertain tax position taken or expected to be taken on an income tax return must be recognized in the 
financial statements at the largest amount that is more likely than not to be sustained upon examination by the relevant 
taxing  authority.  We  regularly  assess  and,  if  required,  establish  accruals  for  income  and  non-income  based  tax 
contingencies  pursuant  to  the  applicable  accounting  standards  that  could  result  from  assessments  of  additional  tax  by 
taxing jurisdictions where we operate. Tax contingencies are subject to a significant amount of judgment and are reviewed 
and  adjusted  on  a  quarterly  basis  in  light  of  changing  facts  and  circumstances  considering  the  outcome  expected  by 
management. As of December 31, 2020 and 2019, we recorded $26.6 million and $23.1 million (including penalties and 
interest and discontinued operations), respectively, of accruals for tax contingencies. Of these amounts, $21.0 million and 
$20.6 million, respectively, were accrued for income taxes and $5.6 million and $2.5 million, respectively, were accrued 
for non-income based taxes. If our actual experience differs from the assumptions and estimates used for recording the 
liabilities, adjustments may be required and would be recorded in the period in which the difference becomes known. 

Subject to the provisions of our tax matters agreement with Exterran Corporation, both parties agreed to indemnify the 
primary  obligor  of any  return  for  tax  periods  beginning  before  and  ending  before  or  after  the  Spin-off  (including  any 
ongoing  or  future  amendments  and  audits  for  these  returns)  for  the  portion  of  the  tax  liability  (including  interest  and 
penalties) that relates to their respective operations reported in the filing. The tax contingencies mentioned above relate to 
tax  matters  for  which  we  are  responsible  in  managing  the  tax  audit.  As  of  December 31, 2020  and  2019,  we  had  an 
offsetting indemnification asset (including penalties and interest) related to our income tax contingencies of $7.9 million 
and $8.5 million, respectively. Additionally, we had an indemnification liability of $1.6 million and $2.8 million as of 
December 31, 2020 and 2019, respectively, for our share of non-income based tax contingencies related to audits being 
managed by Exterran Corporation.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk 

We are exposed to market risk associated with changes in the variable interest rate of our Credit Facility. We use derivative 
instruments to manage our exposure to fluctuations in this variable interest rate and thereby minimize the risks and costs 
associated with financial activities. We do not use derivative instruments for trading or other speculative purposes. 

As of December 31, 2020 and 2019, after taking into consideration interest rate swaps, we had $93.0 million and $113.0 
million, respectively, of outstanding indebtedness that was effectively subject to variable interest rates. A 1% increase in 
the effective interest rate on our outstanding debt subject to variable interest rates at December 31, 2020 and 2019 would 
have resulted in an annual increase in our interest expense of $0.9 million and $1.1 million, respectively. 

See Note 22 (“Derivatives”) to our Financial Statements for further information regarding our use of interest rate swaps in 
managing our exposure to interest rate fluctuations.

Item 9A. Controls and Procedures 

Management’s Evaluation of Disclosure Controls and Procedures 

As of the end of the period covered by this 2020 Form 10-K, our principal executive officer and principal financial officer 
evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act), 
which  are  designed  to  provide  reasonable  assurance  that  we  are  able  to  record,  process,  summarize  and  report  the 
information  required  to  be  disclosed  in  our  reports  under  the  Exchange  Act  within  the  time  periods  specified  in  the 
rules and  forms  of  the  SEC.  Based  on  the  evaluation,  as  of  December 31, 2020,  our  principal  executive  officer  and 
principal  financial  officer  concluded  that  our  disclosure  controls  and  procedures  were  effective  to  provide  reasonable 
assurance  that  the  information  required  to  be  disclosed  in  reports  that  we  file  or  submit  under  the  Exchange  Act  is 
accumulated and communicated to management, and made known to our principal executive officer and principal financial 
officer, on a timely basis to ensure that it is recorded, processed, summarized and reported within the time periods specified 
in the SEC’s rules and forms. 

Management’s Annual Report on Internal Control Over Financial Reporting 

As required by Exchange Act Rules 13a-15(c) and 15d-15(c), our management, including the Chief Executive Officer and 
Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting. 
Management conducted an evaluation of the effectiveness of internal control over financial reporting based on the Internal 
Control —  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission.  Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect 
misstatements. Also, projections of any evaluation of effectiveness as 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.  Based  on  the  results  of  management’s  evaluation  described  above,  management  concluded  that  our 
internal control over financial reporting was effective as of December 31, 2020. 

The effectiveness of internal control over financial reporting as of December 31, 2020 was audited by Deloitte & Touche 
LLP, an independent registered public accounting firm, as stated in its report found within this 2020 Form 10-K. 

Changes in Internal Control over Financial Reporting 

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 
15d-15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal 
control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the shareholders and the Board of Directors of Archrock, Inc. 

Opinion on Internal Control over Financial Reporting 

We have audited the internal control over financial reporting of Archrock, Inc. and subsidiaries (the “Company”) 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 (COSO). 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 COSO. 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States) (PCAOB), the consolidated financial statements and the financial statement schedule as of and for the year ended 
December 31, 2020, of the Company and our report dated February 22, 2021, expressed an unqualified opinion on those 
financial statements and financial statement schedule. 

Basis for Opinion 

The Company’s management is responsible 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 
internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform 
the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained 
in  all  material  respects.  Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting, 
assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal 
control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. 
We believe that our audit provides a reasonable basis for our opinion. 

Definition and Limitations of Internal Control over Financial Reporting 

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

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the shareholders and the Board of Directors of Archrock, Inc. 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Archrock, Inc. and subsidiaries (the “Company”) as of 
December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income, equity, and cash 
flows, for each of the three years in the period ended December 31, 2020, and the related notes and the schedule listed in 
the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present 
fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of 
its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with 
accounting principles generally accepted in the United States of America. 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States)  (PCAOB),  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 and our report dated February 22, 2021 expressed an unqualified opinion on the Company's 
internal control over financial reporting. 

Basis for Opinion 

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion 
on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of 
the  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 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 financial statements. We believe that our audits provide a reasonable basis for 
our opinion. 

Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements 
that  was  communicated  or  required  to  be  communicated  to  the  audit  committee  and  that  (1)  relates  to  accounts  or 
disclosures that are material to the 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 financial statements, 
taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the 
critical audit matter or on the accounts or disclosures to which it relate. 

Long-Lived Asset Impairment - Refer to Note 18 to the financial statements. 

Critical Audit Matter Description

Management’s evaluation of whether to retire compressor units from its active fleet takes into consideration the future 
deployment  of  the  units  that  were  not  of  the  type,  configuration,  condition,  make,  or  model  that  are  cost  efficient  to 
maintain or operate. Once a compressor unit is retired from the active fleet, it is tested for impairment. As such, the timing 
of the identification of compressor units for removal could have a significant impact on the amount of any impairment 
charge. During the year ended December 31, 2020, the Company retired 730 units from the active fleet resulting in an 

F-1 

Table of Contents

asset  impairment  charge  of  $77.6  million.  The  determination  of  impairment  requires  management  to  make  significant 
estimates and assumptions related to the timing of the identification of compressor units for removal. Changes in these 
assumptions could have a significant impact on the amount of impairment charged.   

Auditing  the  decisions  on  when  compressor  units  are  retired  from  the  active  fleet  required  a  high  degree  of  auditor 
judgment  and  an  increased  extent  of  effort  when  performing  audit  procedures  to  evaluate  the  reasonableness  of 
management’s assumptions. 

How the Critical Audit Matter Was Addressed in the Audit 

Our audit procedures related to management’s determination of whether to retire compressor unit from the Company’s 
active fleet included the following, among others: 

•(cid:1) We  tested  the  operating effectiveness  of  internal controls  over  long-lived asset impairment  process, including 
those  over  the  identification  of  units  to  be  retired  and  assessed  for  impairment,  which  includes  the  type, 
configuration, condition, make, or model that are cost efficient to maintain or operate. 

•(cid:1) We  tested the completeness and  accuracy of the compressor  units identified for retirement  by  performing the 

following procedures: 

-(cid:1) Comparing the final listing of retired compressor units to the list evaluated and approved by management. 

-(cid:1)

For a sample of compressor units, determining whether those units were (1) properly segregated from the 
active fleet, (2) identified appropriately in the system, and (3) no longer operating. 

•(cid:1) We evaluated the reasonableness of management’s identification of the compressor units for removal, including 
assessments of type, configuration, condition, make, or model that are cost efficient to maintain or operate, by 
performing the following procedures: 

-(cid:1) Comparing the  rationale  for  compression  units identified  with  historical  rationales  made  for compression 

units of a similar type, configuration, make, or model. 

-(cid:1)

For  a  sample  of  compression  units  not  retired,  making  inquiries  of  management  and  others  within  the 
Company with knowledge of the type, configuration, condition, make, or model and operating costs of the 
specific compressor units to identify if any units not retired exhibit characteristics indicating that they should 
be retired. 

-(cid:1) Comparing the compression units identified to internal communications to management and the Board of 

Directors.  

-(cid:1) Reading available peer company data and other external sources for information supporting or contradicting 

management’s conclusions.

ARCHROCK, INC. 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. Description of Business 

We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We are the leading 
provider of natural gas compression services to customers in the oil and natural gas industry throughout the U.S. and a 
leading  supplier  of aftermarket  services  to  customers that  own  compression equipment  in  the  U.S. We  operate in two 
business segments: contract operations and aftermarket services. Our predominant segment, contract operations, primarily 
includes designing, sourcing, owning, installing, operating, servicing, repairing and maintaining our owned fleet of natural 
gas  compression equipment  to  provide  natural gas compression  services  to  our  customers.  In  our  aftermarket  services 
business,  we  sell  parts  and  components  and provide  operations,  maintenance,  overhaul and  reconfiguration  services to 
customers who own compression equipment. 

2. Basis of Presentation and Significant Accounting Policies 

Basis of Presentation 

Our Financial Statements include Archrock and its subsidiaries, all of which are wholly owned. All intercompany accounts 
and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to 
the current year presentation.

Our Financial Statements are prepared in accordance with GAAP and the rules and regulations of the SEC. The preparation 
of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions 
that affect the reported amount of assets, liabilities, revenues, expenses and disclosures of contingent assets and liabilities. 
Because  of  the  inherent  uncertainties  in  this  process,  actual  future  results  could  differ  from  those  expected  as  of  the 
reporting date. Management believes that the estimates and assumptions used are reasonable. 

Significant Accounting Policies 

Cash and Cash Equivalents 

We  consider  all  highly-liquid  investments  purchased  with  an  original  maturity  of  three months  or  less  to  be  cash 
equivalents. 

Revenue Recognition 

We recognize revenue when control of the promised goods or services is transferred to our customers, in an amount that 
reflects the consideration we are entitled to receive in exchange for those goods or services. Sales and usage-based taxes 
that are collected from the customer are excluded from revenue. 

Contract Operations 

Natural  gas compression  services.  Natural  gas  compression  services  are generally  satisfied over time,  as  the  customer 
simultaneously receives and consumes the benefits provided by these services. Our performance obligation is a series in 
which  the  unit  of  service  is  one month,  as  the  customer  receives  substantially  the  same  benefit  each month  from  the 
services regardless of the type of service activity performed, which may vary. If the transaction price is based on a fixed 
fee, revenue is recognized monthly on a straight-line basis over the period that we are providing services to the customer. 
Amounts  invoiced  to  customers  for  costs  associated  with  moving  our  compression  assets  to  a  customer  site  are  also 
included in the transaction price and are amortized over the initial contract term. We do not consider the effects of the time 
value of money, as the expected time between the transfer of services and payment for such services is less than one year. 

F-9 

Table of Contents

Variable consideration  exists  if customers are  billed  at  a lesser  standby  rate  when a  unit  is  not  running. We  recognize 
revenue  for  such  variable  consideration monthly,  as  the  invoice  corresponds  directly  to  the  value  transferred  to  the 
customer based on our performance completed to date. The rate for standby service is lower to reflect the decrease in costs 
and effort required to provide standby service when a unit is not running. 

Billable Maintenance Service. We also perform billable maintenance service on our natural gas compression equipment 
at the customer’s request on an as-needed basis. The performance obligation is satisfied and revenue is recognized at the 
agreed-upon  transaction  price  at  the  point  in  time  when  service  is  complete  and  the  customer  has  accepted  the  work 
performed and can obtain the remaining benefits of the service that the unit will provide. 

Aftermarket Services 

OTC  Parts  and  Components  Sales.  For  sales  of  OTC  parts  and  components,  the  performance  obligation  is  generally 
satisfied at the point in time when delivery takes place and the customer obtains control of the part or component. The 
transaction price is the fixed sales price for the part stated in the contract. Revenue is recognized upon delivery, as we have 
a present right to payment and the customer has legal title. 

Maintenance, Overhaul and Reconfiguration Services. For our service activities, the performance obligation is satisfied 
over time, as the work performed enhances the customer-controlled asset and another entity would not have to substantially 
re-perform the work we completed if they were to fulfill the remaining performance obligation. The transaction price may 
be a fixed monthly service fee, a fixed quoted fee or entirely variable, calculated on a time and materials basis. 

For service provided based on a fixed monthly fee, the performance obligation is a series in which the unit of service is 
one month. The customer receives substantially the same benefit each month from the service, regardless of the type of 
service  activity  performed,  which  may  vary.  As  the  progress  towards  satisfaction  of  the  performance  obligation  is 
measured based on the passage of time, revenue is recognized monthly based on the fixed fee provided for in the contract. 

For service provided based on a quoted fixed fee, progress towards satisfaction of the performance obligation is measured 
using an input method based on the actual amount of labor and material costs incurred. The amount of the transaction price 
recognized as revenue each reporting period is determined by multiplying the transaction price by the ratio of actual costs 
incurred to date to total estimated costs expected for the service. Significant judgment is involved in the estimation of the 
progress to completion. Any adjustments to the measure of the progress to completion is accounted for on a prospective 
basis. Changes to the scope of service is recognized as an adjustment to the transaction price in the period in which the 
change occurs. 

Service provided based on time and materials are generally short-term in nature and labor rates and parts pricing is agreed 
upon prior to commencing the service. We apply an estimated gross margin percentage, which is fixed based on historical 
time and materials-based service, to actual costs incurred. We evaluate the estimated gross margin percentage at the end 
of each reporting period and adjust the transaction price as appropriate.

Contract Assets and Liabilities 

We recognize a contract asset when we have the right to consideration in exchange for goods or services transferred to a 
customer  when the right  is conditioned on  something other than the passage  of time. We  recognize a contract  liability 
when we have an obligation to transfer goods or services to a customer for which we have already received consideration. 

F-10 

Table of Contents

Concentrations of Credit Risk 

Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and 
trade  accounts  receivable.  Our temporary  cash  investments have a  zero  loss  expectation  because  we  maintain  minimal 
balances in our cash investment accounts and have no history of loss. Trade accounts receivable are due from companies 
of varying size engaged principally in oil and natural gas activities throughout the U.S. We review the financial condition 
of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a 
short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ 
financial resources, the nature of the products and services we provide and the terms of our customer agreements. 

Due to the short-term nature of our trade receivables, we consider the amortized cost to be the same as the carrying amount 
of the receivable, excluding the allowance for credit losses. We recognize an allowance for credit losses when a receivable 
is recorded, even when the risk of loss is remote. We utilize an aging schedule to determine our allowance for credit losses, 
and measure expected credit losses on a collective (pool) basis when similar risk characteristics exist. We rely primarily 
on ratings assigned by external rating agencies and credit monitoring services to assess credit risk and aggregate customers 
first by low, medium or high risk asset pools, and then by delinquency status. We also consider the internal risk associated 
with geographic location and the services we provide to the customer when determining asset pools. If a customer does 
not share similar risk characteristics with other customers, we evaluate the customer’s outstanding trade receivables for 
expected credit losses on an individual basis. Trade receivables evaluated individually are not included in our collective 
assessment.  Each  reporting  period,  we  reassess  our  customers’  risk  profiles  and  determine  the  appropriate  asset  pool 
classification, or perform individual assessments of expected credit losses, based on the customers’ risk characteristics at 
the reporting date. 

The contractual life of our trade receivables is primarily 30 days based on the payment terms specified in the contract. 
Contract operations services are generally billed monthly at the beginning of the month in which service is being provided. 
Aftermarket services billings typically occur when parts are delivered or service is completed. Loss rates are separately 
determined for each asset pool based on the length of time a trade receivable has been outstanding. We analyze two years 
of internal historical loss data, including the effects of prepayments, write-offs and subsequent recoveries, to determine 
our historical loss experience. Our historical loss information is a relevant data point for estimating credit losses, as the 
data closely aligns with trade receivables due from our customers. Ratings assigned by external rating agencies and credit 
monitoring services consider past performance and forecasts of future economic conditions in assessing credit risk. We 
routinely update our historical loss data to reflect our customers’ current risk profile, to ensure the historical data and loss 
rates are relevant to the pool of assets for which we are estimating expected credit losses. 

At December 31, 2020, Chevron U.S.A. Inc. and Williams Partners accounted for 14% and 10% of our trade accounts 
receivable balance, respectively. No customer accounted for more than 10% of our trade accounts receivable balance at 
December 31, 2019. During the years ended December 31, 2020, 2019 and 2018, we recorded bad debt expense of $3.5 
million,  $2.6  million  and  $1.7  million,  respectively. The  following table  summarizes the changes  in our  allowance  for 
credit losses balance during the year ended December 31, 2020 (in thousands):

Property, Plant and Equipment 

Property,  plant  and equipment are  recorded  at  cost and  depreciated  using  the  straight-line  method over their  estimated 
useful lives as follows: 

Compression equipment, facilities and other fleet assets 
Buildings 
Transportation and shop equipment 
Computer hardware and software 
Other 

      3 to 30 years 
20 to 35 years 
3 to 10 years 
3 to 5 years 
3 to 10 years 

Major improvements that extend the useful life of an asset are capitalized and depreciated over the estimated useful life of 
the major improvement, up to seven years. Repairs and maintenance are expensed as incurred. 

Long-Lived Assets 

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, 
for impairment whenever events or changes in circumstances, including the removal of compressors from our active fleet, 
indicate  that  the  carrying  amount  of  an  asset  may  not  be  recoverable.  An  impairment  loss  exists  when  estimated 
undiscounted cash flows expected from the use of the asset and its eventual disposition are less than its carrying amount. 
Impairment  losses  are  recognized  in  the  period  in  which  the  impairment  occurs  and  represent  the  excess  of  the  asset 
carrying value over its fair value. Identifiable intangibles are amortized over the estimated useful life of the asset. 

Leases 

As a result of our adoption of ASC 842 Leases on January 1, 2019, we recorded an operating lease ROU asset and an 
operating lease liability on our consolidated balance sheet. Under previous guidance, operating leases were not recorded 
to the balance sheet. We determine if an arrangement is a lease at inception and determine lease classification and recognize 
ROU assets and liabilities on the lease commencement date based on the present value of lease payments over the lease 
term. As the discount rate implicit in the lease is rarely readily determinable, we estimate our incremental borrowing rate 
using information available at commencement date in determining the present value of the lease payments. The lease term 
includes options to extend when we are reasonably certain to exercise the option. Short-term leases, those with an initial 
term of 12 months or less, are not recorded on the balance sheet. Variable costs such as our proportionate share of actual 
costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are 
recognized in the period in which they are incurred. Operating lease expense for lease payments is recognized on a straight-
line basis over the term of the lease. 

Our facility leases, of which we are the lessee, contain lease and nonlease components, which we have elected to account 
for as a single lease component, as the nonlease components are not significant to the total consideration of the contract 
and separating the nonlease component would have no effect on lease classification. As it relates to our contract operations 
service  agreements  in  which  we  are  a  lessor,  the  services  nonlease  component  is  predominant  over  the  compression 
package lease component and therefore recognition of these agreements will continue to follow the ASC 606 Revenue 
guidance. Under previous guidance, no separation of lease and nonlease components is required, for either lessee or lessor. 

Goodwill

The goodwill acquired in connection with the Elite Acquisition represented the excess of consideration transferred over 
the fair value of the assets and liabilities acquired. We review the carrying amount of our goodwill in the fourth quarter of 
every year, or whenever indicators of potential impairment exist, to determine if the carrying amount of a reporting unit 
exceeds its fair value, including the applicable goodwill. We perform a qualitative assessment to determine whether it is 
more likely than not that the fair value of a reporting unit is impaired. If the fair value is more likely than not impaired, we 
perform a quantitative impairment test to identify impairment and measure the amount of impairment loss to be recognized, 
if any. 

F-12 

  
 
 
 
 
 
 
Table of Contents

Our  qualitative  assessment  includes  consideration  of  various  events  and  circumstances  and  their  potential  impact  to  a 
reporting  unit’s  fair  value,  including  macroeconomic  and  industry  conditions  such  as  a  deterioration  in  our  operating 
environment and limitations on access to capital and other developments in the equity and credit markets, cost factors that 
could have a negative effect on earnings and cash flows, relevant entity-specific and reporting unit-specific events and 
overall financial performance such as declining earnings or cash flows or a sustained decrease in share price. 

The quantitative impairment test (i) allocates goodwill and our other assets and liabilities to our reporting units, contract 
operations and aftermarket services, (ii) calculates the fair value of the reporting units and (iii) determines the impairment 
loss, if any, as the amount by which the carrying amount of the reporting unit exceeds its fair value (limited to the total 
amount of goodwill allocated to that reporting unit). All of the goodwill recognized in the Elite Acquisition was allocated 
to our contract operations reporting unit. The fair value of the contract operations reporting unit is calculated using the 
expected  present  value  of  future  cash  flows  method.  Significant  estimates  are  made  to  determine  future  cash  flows 
including  future  revenues,  costs  and  capital  requirements  and  the  appropriate  risk-adjusted  discount  rate  by  which  to 
discount the estimated future cash flows. 

In  the  first  quarter  of  2020,  the  global  response  to  the  COVID-19  pandemic  significantly  impacted  our  market 
capitalization and estimates of future revenues and cash flows, which triggered the need to perform a quantitative test of 
the fair value of our contract operations reporting unit as of March 31, 2020. The quantitative test determined that the 
carrying amount of our contract operations reporting unit exceeded its fair value and we recorded a full impairment loss 
on goodwill in the first quarter as a result. 

Internal-Use Software 

Certain of our contracts have been deemed to be hosting arrangements that are service contracts, including those related 
to the cloud  migration of  our  ERP  system and cloud  services  for our  new  mobile  workforce, telematics and  inventory 
management tools. Certain costs incurred for the implementation of a hosting arrangement that is a service contract are 
capitalized and amortized on a straight-line basis over the term of the respective contract. Amortization begins for each 
component  of  the  hosting  arrangement  when  the  component  becomes  ready  for  its  intended  use.  Capitalized 
implementation costs are presented in other assets, the same line item in our consolidated balance sheets that a prepayment 
of  the  fees  for  the  associated  hosting  arrangement  would  be  presented.  Amortization  expense  of  the  capitalized 
implementation costs is presented in SG&A, the same line item in our consolidated statements of operations as the expense 
for fees for the associated hosting arrangement. 

Income Taxes 

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets 
and liabilities for the expected future tax consequences of events included in the financial statements. Under this method, 
deferred tax assets and liabilities are determined based on the differences between the financial statements and the tax 
basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. 
The effect of a change in tax rate on deferred tax assets and liabilities is recognized in income in the period of the enactment 
date. 

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making 
such a determination, we consider all available positive and negative evidence including future reversals of existing taxable 
temporary  differences,  projected  future  taxable  income,  tax-planning  strategies  and  results  of  recent  operations.  If  a 
valuation allowance was previously recorded and we subsequently determined we would be able to realize our deferred 
tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax assets’ 
valuation allowance, which would reduce the provision for income taxes. 

We record uncertain tax positions in accordance with the accounting standard on income taxes under a two-step process 
whereby (1) we determine whether it is more likely than not that the tax positions will be sustained based on the technical 
merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize 
the  largest  amount  of tax  benefit  that  is  greater  than  50 percent  likely  to  be  realized  upon  ultimate  settlement  with  the 
related tax authority.

Table of Contents

Hedging and Use of Derivative Instruments 

We use derivative instruments to manage our exposure to fluctuations in the variable interest rate of our Credit Facility 
and  thereby  minimize  the  risks and costs associated  with  financial  activities. We do  not  use  derivative  instruments  for 
trading  or  other  speculative  purposes. We  record interest rate  swaps  on the  balance  sheet as  either  derivative assets  or 
derivative  liabilities  measured  at  their  fair  value.  The  fair  value  of  our  derivatives  is  based  on  the  income  approach 
(discounted cash flow) using market observable inputs, including LIBOR forward curves. Changes in the fair value of the 
derivatives designated as cash flow hedges are recognized as a component of other comprehensive income (loss) until the 
hedged  transaction  affects  earnings.  At  that  time,  amounts  are  reclassified  into  earnings  to  interest  expense,  the  same 
statement of operations line item to which the earnings effect of the hedged item is recorded. Cash flows from derivatives 
designated as hedges are classified in our consolidated statements of cash flows under the same category as the cash flows 
from  the  underlying  assets,  liabilities  or  anticipated  transactions  unless  the  derivative  contract  contains  a  significant 
financing element, in which case, the cash settlements for these derivatives are classified as cash flows from financing 
activities.

To  qualify  for  hedge accounting  treatment,  we  must  formally  document,  designate  and  assess  the effectiveness  of  the 
transactions. We perform quarterly qualitative prospective and retrospective hedge effectiveness assessments unless facts 
and circumstances related to the hedging relationships change such that we can no longer assert qualitatively that the cash 
flow  hedge  relationships  were  and continue to  be highly effective.  If the  necessary  correlation ceases to  exist  or  if the 
anticipated  transaction  is  no  longer  probable,  we  would  discontinue  hedge  accounting  and  apply  mark-to-market 
accounting. Amounts paid or received from interest rate swap agreements are recorded in interest expense and matched 
with the cash flows and interest expense of the debt being hedged, resulting in an adjustment to the effective interest rate. 

3. Recent Accounting Developments 

Accounting Standards Updates Implemented 

Credit Losses 

In  June  2016,  the  FASB  issued  ASU  2016-13,  which  changes  the  impairment  model  for  financial  assets  measured  at 
amortized cost and certain other instruments, and requires entities to use a new current expected credit loss model that 
results in recognition of expected losses over the contractual life of an asset. We adopted ASU 2016-13 on January 1, 2020 
using the modified retrospective approach. The adoption resulted in a $0.2 million decrease in our allowance for credit 
losses and a corresponding pre-tax cumulative effect adjustment to retained earnings in our consolidated balance sheet at 
January  1,  2020.  Comparative  information  has  not  been  restated  and  continues  to  be  reported  under  the  accounting 
standards in effect for those periods. 

Fair Value Measurements 

On January 1, 2020, we adopted ASU 2018-13, which amends the required fair value measurements disclosures related to 
valuation  techniques  and  inputs  used,  uncertainty  in  measurement  and  changes  in  measurements  applied.  These 
amendments resulted in new, prospective disclosures of the range and weighted average of the significant unobservable 
inputs used to develop our Level 3 fair value measurements related to our idle and previously-culled compressors. The 
adoption of ASU 2018-13 had no impact on our consolidated financial statements. 

Income Taxes 

On January 1, 2020, we adopted ASU 2019-12, which simplifies the accounting for income taxes by, among other things, 
removing  certain  exceptions  related  to  the  incremental  approach  for  intraperiod  tax  allocation,  the  year-to-date  loss 
methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities on outside 
basis  differences.  ASU  2019-12  also  clarifies  other  aspects  of  the  accounting  for  income  taxes  in  order  to  improve 
consistency of application. The adoption of ASU 2019-12 had no impact on our consolidated financial statements.

Accounting Standards Updates Not Yet Implemented 

Reference Rate Reform 

In March 2020, the FASB issued ASU 2020-04, which provides optional expedients and exceptions for applying GAAP 
to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be 
discontinued as a result of reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 through 
December  31,  2022.  Entities  may  elect  to  apply  the  amendments  for  contract  modifications  as  of  any  date  from  the 
beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an 
interim period that includes or is subsequent to March 12, 2020. Modifications to our interest rate swap and Credit Facility 
agreements during the effective period of this amendment will be assessed and if the modifications meet the criteria for 
the optional expedients and exceptions, we intend to adopt ASU 2020-04 and apply the amendments as applicable.

4. Business Transactions

July 2020 Disposition 

On July 9, 2020, we completed the sale of the turbocharger business included within our aftermarket services segment. In 
connection with the sale, we entered into a supply agreement to purchase a minimum amount of turbocharger goods and 
services over a two-year term. In addition to cash of $9.5 million received upon closing, an additional $3.0 million is due 
on the first anniversary of the closing date and $3.5 million will be received through the purchase of turbocharger goods 
and services under the supply agreement. During the year ended December 31, 2020, we received cash of $0.7 million 
under  the  supply  agreement  and  recognized  a  gain  on  the  sale  of  $9.3  million  in  gain  on  sale  of  assets,  net  in  our 
consolidated statements of operations.

March 2020 Disposition 

On March 1, 2020, we completed the sale of certain contract operations customer service agreements and approximately 
200  compressors,  comprising  approximately  35,000  horsepower,  used  to  provide  compression  services  under  those 
agreements  as  well  as  other  assets  used  to  support  the  operations.  We  allocated  customer-related  and  contract-based 
intangible assets and goodwill based on a ratio of the horsepower sold relative to the total horsepower of the asset group. 
We recognized a gain on the sale of $3.2 million in gain on sale of assets, net in our consolidated statements of operations 
during the year ended December 31, 2020. 

Elite Acquisition 

On August 1, 2019, we completed the Elite Acquisition whereby we acquired from Elite Compression substantially all of 
its assets, including a fleet of predominantly large compressors comprising approximately 430,000 horsepower, vehicles, 
real property and inventory, and certain liabilities for aggregate consideration consisting of $214.0 million in cash and 
21.7  million  shares  of  common  stock  with  an  acquisition  date  fair  value  of  $225.9  million.  The  cash  portion  of  the 
acquisition was funded with borrowings on the Credit Facility. 

F-15 

Table of Contents

The Elite Acquisition was accounted for using the acquisition method, which requires, among other things, assets acquired 
and liabilities assumed to be recorded at their fair value on the acquisition date. The excess of the consideration transferred 
over those fair values is recorded as goodwill. The following table summarizes the purchase price allocation based on the 
estimated fair values of the acquired assets and liabilities as of the acquisition date (in thousands):

Our valuation methodology and significant inputs for fair value measurements are detailed by asset class below. The fair 
value measurements for property, plant and equipment and intangible assets are based on significant inputs that are not 
observable in the market and therefore represent Level 3 measurements. 

Goodwill 

The goodwill resulting from the acquisition was attributable to the expansion of our services in various regions in which 
we currently operate and was allocated to our contract operations segment. The goodwill had an indefinite life that was to 
be reviewed annually for impairment or more frequently if indicators of potential impairment existed. All of the goodwill 
recorded for this acquisition is expected to be deductible for U.S. federal income tax purposes. See Note 9 (“Goodwill”) 
for details on the 2020 impairment of our goodwill. 

Property, Plant and Equipment 

The property, plant and equipment is primarily comprised of compression equipment that will be depreciated on a straight-
line basis over an estimated average remaining useful life of 15 years. The fair value of the property, plant and equipment 
was determined using the cost approach, whereby we estimated the replacement cost of the assets by evaluating recent 
purchases of similar assets or published data, and then adjusted replacement cost for physical deterioration and functional 
and economic obsolescence, as applicable. 

Intangible Assets 

The  intangible  assets  consist  of  customer  relationships  that  have  an  estimated  useful  life  of  15 years.  The  amount  of 
intangible assets and their associated useful life were determined based on the period over which the assets are expected 
to  contribute  directly  or  indirectly  to  our  future  cash  flows.  The  fair  value  of  the  identifiable  intangible  assets  was 
determined using the multi-period excess earnings method, which is a specific application of the discounted cash flow 
method, an income approach, whereby we estimated and then discounted the future cash flows of the intangible asset by 
adjusting  overall  business  revenue  for attrition,  obsolescence,  cost  of  sales,  operating  expenses,  taxes and  the  required 
returns attributable to other contributory assets acquired. Significant estimates made in arriving at expected future cash 
flows included our expected customer attrition rate and the amount of earnings attributable to the assets. To discount the 
estimated future cash flows, we utilized a discount rate that was at a premium to our weighted average cost of capital to 
reflect the less liquid nature of the customer relationships relative to the tangible assets acquired.

attributable to the assets acquired from the date of acquisition, August 1, 2019, through December 31, 2019 was $33.2 
million. We are unable to provide earnings attributable to the assets and liabilities acquired since the date of acquisition as 
we do not prepare full stand-alone earnings reports for those assets and liabilities. 

Harvest Sale 

On August 1, 2019, we completed an asset sale in which Harvest acquired from us approximately 80,000 active and idle 
compression horsepower, vehicles and parts inventory for cash consideration of $30.0 million. We recorded a $6.6 million 
gain  on  this  sale  to  gain  on  sale  of  assets,  net  in  our  consolidated  statements  of  operations  during  the year  ended 
December 31, 2019. The assets were previously reported under our contract operations segment. 

5. Discontinued Operations

Spin-off of Exterran Corporation 

In 2015 we completed the Spin-off. In order to effect the Spin-off and govern our relationship with Exterran Corporation 
after the Spin-off, we entered into several agreements with Exterran Corporation, which include, but are not limited to, the 
separation and distribution agreement and the tax matters agreement. 

The  separation  and distribution agreement  specifies, among  other things,  our  right to  promptly  receive  payments from 
Exterran  Corporation  based  on  a  notional  amount  corresponding  to  payments  received  by  Exterran  Corporation  from 
PDVSA in respect of the sale of Exterran Corporation’s previously nationalized assets after such amounts are collected by 
Exterran Corporation. During the years ended December 31, 2020 and 2018, we received $0.7 million and $18.7 million, 
respectively, from Exterran Corporation pursuant to this term of the separation and distribution agreement. We entered 
into  an  assignment  from  Exterran  Corporation  in  2020  such  that  any  future  payments  by  PDVSA  would  be  received 
directly by us.

of unrecognized tax benefits (including interest and penalties) related to Exterran Corporation operations prior to the Spin-
off recorded to noncurrent liabilities associated with discontinued operations in our consolidated balance sheets. We had 
an offsetting indemnification asset of $7.9 million and $8.5 million related to these unrecognized tax benefits recorded to 
noncurrent assets associated with discontinued operations as of December 31, 2020 and 2019, respectively.

Depreciation expense was $177.5 million, $172.8 million and $158.4 million during the years ended December 31, 2020, 
2019  and  2018,  respectively.  Assets  under construction  of $17.6  million and  $51.0  million at  December 31, 2020 and 
2019, respectively, were primarily included in compression equipment, facilities and other fleet assets. 

8. Leases 

We have operating leases and subleases for office space, temporary housing, storage and shops. Our leases have remaining 
lease terms  of  less  than one  year to approximately  10  years  and  most  include  options to extend  the lease term, at  our 
discretion, for an additional one to five years. We are not, however, reasonably certain that we will exercise any of the 
options to extend and as such, they have not been included in the remaining lease terms.

Our  goodwill  was  recognized  in  connection  with  the  Elite  Acquisition  and  represents  the  excess  of  consideration 
transferred  over  the  fair  value  of  the  assets  and  liabilities  acquired.  All  of  the  goodwill  was  allocated  to  our  contract 
operations reporting unit. We review the carrying amount of our goodwill in the fourth quarter of every year, or whenever 
indicators  of  potential  impairment  exist,  to  determine  if  the  carrying  amount  of  our  contract  operations  reporting  unit 
exceeds its fair value, including the goodwill. Beginning in the first quarter of 2020, the COVID-19 pandemic caused a 
significant deterioration in global macroeconomic conditions, including a collapse in the demand for oil coupled with an 
oversupply of oil, which commenced substantial spending cuts by our customers and a decline in production. This global 
response to the pandemic significantly impacted our market capitalization and estimates of future revenues and cash flows, 
which triggered  the  need  to perform a  quantitative  test  of  the  fair  value of  our  contract  operations  reporting  unit as  of 
March  31,  2020.  The  quantitative  test  determined  that  the  carrying  amount  of  our  contract  operations  reporting  unit 
exceeded its fair value and we recorded a full impairment loss on goodwill in the first quarter as a result. 

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and 
assumptions, which have a significant impact on the fair value determined. We determine the fair value of our reporting 
unit using an equal weighting of both the expected present value of future cash flows and a market approach. The present 
value of future cash flows is estimated using our most recent forecast and the weighted average cost of capital. The market 
approach uses a market multiple on the earnings before interest expense, provision for income taxes and depreciation and 
amortization  expense  of  comparable  peer  companies.  Significant  estimates  for  our  reporting  unit  included  in  our 
impairment analysis are our cash flow forecasts, our estimate of the market’s weighted average cost of capital and market 
multiples.

We capitalize incremental costs to obtain a contract with a customer if we expect to recover those costs. Capitalized costs 
include commissions paid to our sales force to obtain contract operations contracts. We expense commissions paid for 
sales of service contracts and OTC parts and components within our aftermarket services segment, as the amortization 
period is less than one year. We had contract costs of $3.2 million and $4.8 million associated with sales commissions 
recorded in our consolidated balance sheets at December 31, 2020 and 2019, respectively. 

We capitalize costs incurred to fulfill a contract if those costs relate directly to a contract, enhance resources that we will 
use in satisfying performance obligations and if we expect to recover those costs. Capitalized costs incurred to fulfill our 
customer contracts include freight charges to transport compression assets before transferring services to the customer and 
mobilization  activities  associated  with  our  contract  operations  services.  Aftermarket  services  fulfillment  costs  are 
recognized based on the percentage-of-completion method applicable to the customer contract and do not typically result 
in the recognition of contract costs. We had contract costs of $26.0 million and $38.1 million associated with freight and 
mobilization recorded in our consolidated balance sheets at December 31, 2020 and 2019, respectively.

Contract operations obtainment and fulfillment costs are amortized based on the transfer of service to which the assets 
relate,  which  is  estimated to be 38  months  based on average  contract term,  including  anticipated renewals. We  assess 
periodically whether the 38-month estimate fairly represents the average contract term and adjust as appropriate. Contract 
costs associated with commissions are amortized to SG&A. Contract costs associated with freight and mobilization are 
amortized to cost of sales (excluding depreciation and amortization). During the years ended December 31, 2020, 2019 
and 2018, we amortized $3.0 million, $2.6 million and $1.5 million, respectively, related to sales commissions and $23.6 
million, $20.7 million and $13.4 million, respectively, related to freight and mobilization. 

12. Hosting Arrangements 

In the fourth  quarter  of  2018  we  began  a  process and technology transformation  project that  will,  among  other  things, 
upgrade or replace our existing ERP, supply chain and inventory management systems and expand the remote monitoring 
capabilities of our compression fleet. Included in this project are hosting arrangements that are service contracts related to 
the  cloud  migration  of  our  ERP  system  and  cloud  services  for  our  new  mobile  workforce,  telematics  and  inventory 
management tools. 

As of December 31, 2020 and 2019, we had $7.7 million and $5.5 million, respectively, of capitalized implementation 
costs related to our hosting arrangements that are service contracts included in other assets in our consolidated balance 
sheets.  Accumulated  amortization  was  $0.3  million  at  December 31, 2020.  We  recorded  $0.3  million  of  amortization 
expense to SG&A in our consolidated statements of operations during the year ended December 31, 2020. 

During the year ended December 31, 2020, we impaired $1.6 million of capitalized implementation costs related to the 
hosting arrangements of the mobile workforce component of our project due to the termination of the agreement, which 
was included in long-lived and other asset impairment in our consolidated statements of operations.

As of December 31, 2020, there were $12.4 million letters of credit outstanding under the Credit Facility and the applicable 
margin on borrowings outstanding was 2.4%. The weighted average annual interest rate on the outstanding balance under 
the  Credit  Facility,  excluding  the  effect  of  interest  rate  swaps,  was  2.7%  and  4.3%  at  December 31, 2020  and  2019, 
respectively. As a result of the facility’s ratio requirements (see below), $444.1 million of the $844.6 million of undrawn 
capacity  was  available  for  additional  borrowings  as  of  December 31, 2020.  As  of  December 31, 2020,  we  were  in 
compliance with all covenants under the Credit Facility agreement. 

Amendment No. 2

On November 8, 2019, we amended the Credit Facility to, among other things: 

•(cid:1)

•(cid:1)

extend  the  maturity  date  of  the  Credit  Facility  from  March 30,  2022  to  November 8,  2024, effective  as  of the 
execution of Amendment No. 2; and 
change  the  applicable  margin  for  borrowings  under  the  Credit  Facility  to  those  discussed  in  “Other  Facility 
Terms” below. 

We incurred $6.4 million in transaction costs related to Amendment No. 2, which were included in other assets in our 
consolidated balance sheet and are being amortized over the term of the Credit Facility. 

Amendment No. 1

In February 2018, we amended the Credit Facility to, among other things: 

•(cid:1)

•(cid:1)

increase the maximum Total Debt to EBITDA ratios, as defined in the Credit Facility agreement (see below for 
the revised ratios), effective as of the execution of Amendment No. 1 in February 2018; and 
effective upon completion of the Merger in April 2018:

increase the amount available for the issuance of letters of credit from $25.0 million to $50.0 million; 
and 
increase  the  basket  sizes  under  certain  covenants  including  covenants  limiting  our  ability  to  make 
investments, incur debt, make restricted payments, incur liens and make asset dispositions. 

We incurred $3.3 million in transaction costs related to Amendment No. 1, which were included in other assets in our 
consolidated balance sheet and are being amortized over the term of the Credit Facility. 

Other Facility Terms

Subject to certain conditions, including the approval by the lenders, we are able to increase the aggregate commitments 
under  the  Credit  Facility  by  up  to an  additional  $250.0  million.  Portions  of the Credit  Facility  up  to  $50.0  million  are 
available for the issuance of swing line loans. 

The Credit Facility bears interest at a base rate or LIBOR, at our option, plus an applicable margin. Depending on our 
leverage ratio, the applicable margin varies (i) in the case of LIBOR loans, from 2.00% to 2.75% and (ii) in the case of 
base rate loans, from 1.00% to 1.75%. The base rate is the highest of (i) the prime rate announced by JPMorgan Chase 
Bank, (ii) the Federal Funds Effective Rate plus 0.50% and (iii) one-month LIBOR plus 1.00%. 

Additionally, we are required to pay commitment fees based on the daily unused amount of the Credit Facility at a rate of 
0.375%. We incurred $2.0 million, $1.9 million and $2.1 million in commitment fees on the daily unused amount of our 
facilities during the years ended December 31, 2020, 2019 and 2018, respectively. 

The  Credit  Facility  borrowing  base  consists  of  eligible  accounts  receivable,  inventory  and  compressors,  the  largest  of 
which is compressors. Borrowings under the Credit Facility are secured by substantially all of our personal property assets 
and our Significant Domestic Subsidiaries (as defined in the Credit Facility agreement), including all of the membership 
interests of our Domestic Subsidiaries (as defined in the Credit Facility agreement). 

The Credit Facility agreement contains various covenants including, but not limited to, restrictions on the use of proceeds 
from  borrowings and limitations on  our ability  to  incur  additional  indebtedness,  engage in transactions  with  affiliates, 
merge or consolidate, sell assets, make certain investments and acquisitions, make loans, grant liens, repurchase equity 
and pay distributions. The Credit Facility agreement also contains various covenants requiring mandatory prepayments 
from the net cash proceeds of certain asset transfers. 

As of December 31, 2020, the following consolidated financial ratios, as defined in our Credit Facility agreement, were 
required: 

EBITDA to Interest Expense 
Senior Secured Debt to EBITDA 
Total Debt to EBITDA 

January 1 through June 30, 2020 
Thereafter (1) 

2.5 to 1.0 
3.5 to 1.0 

5.50 to 1.0 
5.25 to 1.0 

(1)(cid:1)

Subject to a temporary increase to 5.50 to 1.0 for any quarter during which an acquisition satisfying certain thresholds is completed and for the two 
quarters immediately following such quarter.

Former Credit Facility 

In April 2018, in connection with the Merger, the Former Credit Facility was terminated. Upon termination, we repaid 
$63.2 million in borrowings and accrued and unpaid interest and fees outstanding. All commitments under the Former 
Credit Facility were terminated and the $15.4 million of letters of credit outstanding under the Former Credit Facility were 
converted to letters of credit under the Credit Facility. As a result of the termination, we recorded a debt extinguishment 
loss of $2.5 million. We were in compliance with all covenants under the Former Credit Facility through its closing.

2028 Notes and 2027 Notes 

On December 17, 2020, we completed a private offering of $300.0 million aggregate principal amount of 6.25% senior 
notes due April 2028, which were issued pursuant to the indenture under which we completed a private offering of $500.0 
million aggregate principal amount of 6.25% senior notes in December 2019. The notes of the two offerings have identical 
terms and are treated as a single class of securities. The $300.0 million of notes were issued at 104.875% of their face 
value and have an effective interest rate of 5.6%. We received net proceeds of $309.9 million, after deducting issuance 
costs of $4.7 million, from our December 2020 offering and net proceeds of $491.8 million, after deducting issuance costs 
of $8.2 million, from our December 2019 offering. 

In March 2019, we completed a private offering of $500.0 million aggregate principal amount of 6.875% senior notes due 
April 2027 and received net proceeds of $491.2 million after deducting issuance costs of $8.8 million. 

The  net  proceeds  from  the  2027  Notes  and  2028  Notes  were  used  to  repay  borrowings  outstanding  under  our  Credit 
Facility. Issuance costs related to the 2027 Notes and 2028 Notes are considered deferred financing costs, and together 
with  the  issue  premium  of  the  December  2020  offering  of  2028  Notes,  are  recorded  within  long-term  debt  in  our 
consolidated balance sheets and are being amortized to interest expense in our consolidated statements of operations over 
the terms of the notes. 

The  2027  Notes and  2028  Notes are  fully  and unconditionally  guaranteed,  jointly and  severally,  on a  senior  unsecured 
basis by us and all of our existing subsidiaries, other than Archrock Partners, L.P. and APLP Finance Corp., which are co-
issuers of both offerings, and certain of our future subsidiaries. The 2027 Notes and 2028 Notes and the guarantees rank 
equally in right of payment with all of our and the guarantors’ existing and future senior indebtedness. 

The 2027 Notes and 2028 Notes may be redeemed at any time, in whole or in part, at specified redemption prices and 
make-whole premiums, plus any accrued and unpaid interest. 

2022 Notes 

On April 1, 2020, the 2022 Notes were redeemed at 100% of their $350.0 million aggregate principal amount plus accrued 
and unpaid interest of $10.5 million with borrowings under the Credit Facility. A debt extinguishment loss of $4.0 million 
related to the redemption was recognized during the year ended December 31, 2020. 

2021 Notes 

In April 2019, the 2021 Notes were redeemed at 100% of their $350.0 million aggregate principal amount plus accrued 
and unpaid interest of $0.2 million with borrowings under the Credit Facility. We recorded a debt extinguishment loss of 
$3.7 million related to the redemption during the year ended December 31, 2019.

15. Accumulated Other Comprehensive Income (Loss) 

Components of comprehensive income (loss) are net income (loss) and all changes in equity during a period except those 
resulting from transactions with owners. Our accumulated other comprehensive income (loss) consists of changes in the 
fair  value  of  our  interest  rate  swap  derivative  instruments,  net  of  tax,  which  are  designated  as  cash  flow  hedges, 
amortization of terminated interest rate swaps and adjustments related to changes in our ownership of the Partnership as 
the result of the Merger. 

The following table presents the changes in accumulated other comprehensive income (loss) of our derivative cash flow 
hedges, net of tax and excluding noncontrolling interest (in thousands):

16. Equity 

Elite Acquisition 

In August 2019, we completed the Elite Acquisition. A portion of the acquisition’s purchase price was funded through the 
issuance of 21.7 million shares of common stock with an acquisition date fair value of $225.9 million, which was recorded 
to  common  stock  and  additional  paid-in  capital  in  our  consolidated  statements  of  equity.  See Note 4 (“Business 
Transactions”) for further details of this acquisition. 

Merger Transaction 

In April 2018, we completed the Merger and issued 57.6 million shares of our common stock to acquire the 41.2 million 
common  units  of  the  Partnership  not owned  by  us  prior to the  Merger at  a  fixed  exchange  ratio  of  1.40  shares  of  our 
common  stock  for  each  Partnership  common  unit  for  total  implied  consideration  of  $625.3  million.  Additionally,  the 
incentive distribution rights in the Partnership, all of which we owned prior to the Merger, were canceled and ceased to 
exist. As a result of the Merger, the Partnership’s common units are no longer publicly traded. 

As we controlled the Partnership prior to the Merger and continue to control the Partnership after the Merger, we accounted 
for the change in our ownership interest in the Partnership as an equity transaction in the second quarter of 2018. No gain 
or loss was recognized in our consolidated statements of operations as a result of the Merger.

Prior to the Merger, public unitholders held a 57% ownership interest in the Partnership and we owned the remaining 43% 
equity interest. The equity interests in the Partnership that were owned by the public prior to the Merger are reflected in 
noncontrolling interest in our consolidated statements of equity. The earnings of the Partnership that were attributed to its 
common units held by the public prior to the Merger are reflected in net income attributable to noncontrolling interest in 
our consolidated statements of operations. 

The tax effects of the Merger were reported as adjustments to other assets, noncurrent assets associated with discontinued 
operations, deferred tax liabilities, additional paid-in capital and other comprehensive income. The change in ownership 
and tax step up from the consideration given in the Merger caused us to record a $156.0 million deferred tax asset, which 
resulted in an overall $52.2 million net deferred tax asset. We evaluated the realizability of our resulting net deferred tax 
asset position by assessing the available positive and negative evidence and concluded, based on the weight of the evidence, 
that a $50.8 million valuation allowance was required. The $105.2 million net tax impact of the change in deferred tax 
assets and the valuation allowance was recorded as an offsetting increase to additional paid-in capital. 

We incurred $0.5 million and $10.2 million of transaction costs directly attributable to the Merger during the years ended 
December 31, 2019 and 2018, respectively, including financial advisory, legal service and other professional fees, which 
were recorded to transaction-related costs in our consolidated statements of operations.

Freight  billings to  customers  for the transport  of compression assets,  customer-specified  modifications  of compression 
assets and milestone billings on aftermarket services often result in a contract liability. As of December 31, 2020 and 2019, 
our contract liabilities were $4.6 million and $11.4 million, respectively, which were included in deferred revenue and 
other liabilities in our consolidated balance sheets. The decrease in the contract liability balance during the year ended 
December 31, 2020 was primarily due to $19.5 million recognized as revenue during the period, partially offset by revenue 
deferral of $12.7 million, each primarily related to freight billings and milestone billings on aftermarket services. 

18. Long-Lived and Other Asset Impairment 

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, 
for impairment whenever events or changes in circumstances, including the removal of compressors from our active fleet, 
indicate that the carrying amount of an asset may not be recoverable. 

In the first quarter of 2020, we determined that the impairment of our contract operations reporting unit’s goodwill was an 
indicator  of  potential  impairment  of  the  carrying  amount  of  our  long-lived  assets,  including  our  compressor  fleet  and 
associated customer and contract-based intangible assets. Accordingly, we performed a quantitative impairment test of our 
long-lived assets, by which we determined that they were not also impaired. No similar impairment has been indicated 
subsequent to the first quarter. 

Compression Fleet 

We  periodically  review  the  future  deployment  of  our  idle  compression  assets  for  units  that  are  not  of  the  type, 
configuration,  condition,  make  or  model  that  are  cost  efficient  to  maintain  and  operate.  Based  on  these  reviews,  we 
determine that certain idle compressors should be retired from the active fleet. The retirement of these units from the active 
fleet triggers a review of these assets for impairment and as a result of our review, we may record an asset impairment to 
reduce the book value of each unit to its estimated fair value. The fair value of each unit is estimated based on the expected 
net sale proceeds compared to other fleet units we recently sold, a review of other units recently offered for sale by third 
parties or the estimated component value of the equipment we plan to use. 

In connection with our review of our idle compression assets, we evaluate for impairment idle units that were culled from 
our  fleet  in  prior years  and  are  available  for  sale.  Based  on  that  review,  we  may  reduce  the  expected  proceeds  from 
disposition and record additional impairment to reduce the book value of each unit to its estimated fair value. 

The following table presents the results of our compression fleet impairment review as recorded to our contract operations 
segment (dollars in thousands):

19. Restructuring Charges  

During the first quarter of 2020, we completed restructuring activities to further streamline our organization and more fully 
align our teams to improve our customer service and profitability. We incurred severance costs during the first quarter 
related to these activities. No additional costs will be incurred related to these restructuring activities. 

In response to the decreased activity level of our customers that resulted from the COVID-19 pandemic beginning in the 
second quarter of 2020, we have incurred severance costs to right-size our business. We are not currently able to estimate 
the total amount of restructuring costs to be incurred as a result of the COVID-19 pandemic, as the magnitude and duration 
of the pandemic and its impact on our operations remain difficult to predict. 

During the third quarter of 2020, a plan to dispose of certain non-core properties was approved by management. We are 
not currently able to estimate the total amount of restructuring costs to be incurred as a result of our property disposals, as 
the timing of the disposals and magnitude of the financial impact of their ultimate disposition remain difficult to predict. 

The  severance and  property disposal  costs  incurred  under  the above  restructuring plans  were  recorded  to  restructuring 
charges in our consolidated statements of operations.

See “Tax Attributes and Valuation Allowances” below for further details. 
The 2020 and 2019 net deferred tax asset are reflected in our consolidated balance sheets as deferred tax assets of $56.9 million and $36.6 million, 
respectively, and deferred tax liabilities of $0.7 million and $1.3 million, respectively. 

Both the 2020 and 2019 balances are based on a U.S. federal tax rate of 21%.

Tax Attributes and Valuation Allowances 

Pursuant to Sections 382 and 383 of the Code, utilization of loss and credit carryforwards are subject to annual limitations 
due to any ownership changes of 5% stockholders. In general, an ownership change, as defined by Section 382, results 
from transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more 
than 50% over a rolling three-year period. In 2018, the common stock we issued in the Merger caused a new ownership 
change to occur for Archrock. The limitations from this ownership change may cause us to pay U.S. federal income taxes 
earlier; however, we do not currently expect that any loss carryforwards or credit carryforwards will expire as a result of 
any 382 or 383 limitations. Our ability to utilize loss carryforwards and credit carryforwards against future U.S. federal 
taxable income and future U.S. federal income tax may be limited in the future if we have another 50% or more ownership 
change in our 5% stockholders. 

We record valuation allowances when it is more likely than not that some portion or all of our deferred tax assets will not 
be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income 
of the appropriate character and in the appropriate taxing jurisdictions in the future. If we do not meet our expectations 
with respect to taxable income, we may not realize the full benefit from our deferred tax assets, which would require us to 
record a valuation allowance in our tax provision in future years. As of each reporting date, we consider new evidence to 
evaluate the realizability of our net deferred tax asset position by assessing the available positive and negative evidence. 
Changes to the valuation allowance are reflected in the statement of operations.

In 2018, the change in ownership and tax step up from the consideration given in the Merger caused us to record a $156.0 
million deferred tax asset, which resulted in an overall $52.2 million net deferred tax asset, of which $46.6 million and 
$5.6 million related to continuing operations and discontinued operations, respectively. As of December 31, 2018, we had 
incurred a three-year cumulative book loss, which outweighed the positive evidence of projected future taxable income. 
Based on the weight of the evidence, we concluded that a $50.8 million valuation allowance was required, of which $45.2 
million and $5.6 million were recorded to continuing operations and discontinued operations, respectively. The tax impact 
from the Merger was accounted for as an equity transaction; therefore, the valuation allowance was recorded as a decrease 
to additional paid-in capital. 

As of December 31, 2019, we achieved a three-year cumulative book income, and together with other positive and negative 
evidence, we concluded that there is sufficient positive evidence of projected future taxable income to release the $50.8 
million valuation allowance previously required for our overall net deferred tax asset position. This release was offset by 
a $0.6 million increase in the valuation allowance on our state NOL deferred tax asset. The overall impact of the change 
in the valuation allowance was recorded as a $50.2 million benefit from income taxes in our consolidated statements of 
operations and a $50.2 million increase in deferred tax assets in our consolidated balance sheets, of which $44.6 million 
and $5.6 million were recorded to continuing operations and discontinued operations, respectively. 

The amount of our deferred tax assets considered realizable could be adjusted if projections of future taxable income are 
reduced or objective negative evidence in the form of a three-year cumulative loss is present or both. Should we no longer 
have a level of sustained profitability, excluding nonrecurring charges, we will have to rely more on our future projections 
of taxable income to determine if we have an adequate source of taxable income for the realization of our deferred tax 
assets, namely NOL carryforwards and tax credit carryforwards. This may result in the need to record a valuation allowance 
against all or a portion of our deferred tax assets. 

At  December 31,  2020,  we  had  U.S. federal  and  state  NOL  carryforwards  of  $696.3  million  and  $257.6  million, 
respectively, included in our NOL deferred tax asset that are available to offset future taxable income. If not used, the 
federal and state NOL carryforwards will begin to expire in 2025 and 2021, respectively, though $457.3 million of the 
U.S. federal and $88.3 million of the state NOL carryforwards have no expiration date. In connection with the state NOL 
deferred tax asset, we recorded a valuation allowance of $1.0 million and $0.8 million as of December 31, 2020 and 2019, 
respectively. 

At  December 31,  2020,  we  had  U.S.  federal  and  state  tax  credit  carryforwards  of  $2.5  million  and  $0.2  million, 
respectively. If not used, the federal and state tax credit carryforwards will begin to expire in 2037 and 2040, respectively.

We had $18.9 million, $18.5 million and $19.6 million of unrecognized tax benefits at December 31, 2020, 2019 and 2018, 
respectively,  of  which  $2.9  million,  $3.2  million  and  $6.9  million,  respectively,  would  affect  the  effective  tax  rate  if 
recognized and $7.9 million, $8.3 million and $6.9 million, respectively, would be reflected in income from discontinued 
operations, net of tax if recognized. 

We recorded $2.1 million, $2.1 million and $2.2 million of potential interest expense and penalties related to unrecognized 
tax benefits associated with uncertain tax positions (including discontinued operations) in our consolidated balance sheets 
as of the years ended December 31, 2020, 2019 and 2018, respectively. To the extent interest and penalties are not assessed 
with respect to uncertain tax positions, amounts accrued will be reduced and reflected as reductions in income tax expense. 
During  each  of  the  years  ended  December 31, 2020  and  2019,  we  recorded  releases  of  potential  interest  expense  and 
penalties of $0.1 million and in the year ended December 31, 2018, we recorded $0.7 million of potential interest expense 
and penalties in our consolidated statements of operations. 

Subject to the provisions of our tax matters agreement with Exterran Corporation, both parties agreed to indemnify the 
primary  obligor  of any  return  for  tax  periods  beginning  before  and  ending  before  or  after  the  Spin-off  (including  any 
ongoing  or  future  amendments  and  audits  for  these  returns)  for  the  portion  of  the  tax  liability  (including  interest  and 
penalties) that relates to their respective operations reported in the filing. As of December 31, 2020 and 2019, we recorded 
an  indemnification  asset  (including  penalties  and  interest)  of  $7.9  million  and  $8.5 million,  respectively,  related  to 
unrecognized tax benefits in our consolidated balance sheets. 

We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous 
state jurisdictions. U.S. federal income tax returns are generally subject to examination for up to three years after filing the 
returns. Due to our NOL carryforwards, our U.S. federal income tax returns can be examined back to the inception of our 
NOL  carryforwards;  therefore,  expanding  our  examination  period  beyond  20 years.  In  2020,  the  IRS  completed  their 
examination of our 2014 and 2015 tax years. Due to this audit being related to tax periods that commenced prior to the 
Spin-off, Exterran Corporation was also involved in the audit. The tax adjustments recorded from this audit did not have 
a material impact on our consolidated financial position or results of operations. 

State income tax returns are generally subject to examination for a period of three to five years after filing the returns. 
However,  the  state  impact  of  any  U.S. federal  audit  adjustments  and  amendments  remains  subject  to  examination  by 
various states for up to one year after formal notification to the states. We are currently involved in two state audits. During 
the years ended December 31, 2019 and 2018, we settled certain state audits, which resulted in refunds of $2.4 million and 
$1.7 million, respectively, and reductions in previously-accrued uncertain tax benefits of $4.4 million and $3.5 million, 
respectively. As of December 31, 2020, we did not have any state audits underway that we believe would have a material 
impact on our consolidated financial statements. 

As of December 31, 2020, we believe it is reasonably possible that $2.7 million of our unrecognized tax benefits, including 
penalties, interest and discontinued operations, will be reduced prior to December 31, 2021 due to the settlement of audits 
or  the  expiration  of  statutes  of  limitations  or  both.  However,  due  to  the  uncertain  and  complex  application  of  the  tax 
regulations, it is possible that the ultimate resolution of these matters may result in liabilities that could materially differ 
from this estimate.

CARES Act 

On March 27, 2020, President Trump signed into law the CARES Act, which includes, among other things, refundable 
payroll tax credits, deferment of employer-side social security payments, NOL carryback periods, alternative minimum 
tax  credit  refunds,  modifications  to  the  net  interest  deduction  limitations  and  technical  corrections  to  tax  depreciation 
methods  for  qualified  improvement  property.  The  CARES  Act  provisions  did  not  have  a  material  impact  on  our 
consolidated financial statements. Future regulatory guidance under the CARES Act or additional legislation enacted by 
Congress in connection with the COVID-19 pandemic could impact our tax provision in future periods.

21. Earnings per Share 

Basic net income (loss) per common share attributable to Archrock common stockholders is computed using the two-class 
method, which is an earnings allocation formula that determines net income (loss) per share for each class of common 
stock and participating security according to dividends declared and participation rights in undistributed earnings. Under 
the  two-class  method,  basic  net  income  (loss)  per  common  share  attributable  to  Archrock  common  stockholders  is 
determined by dividing net income (loss) attributable to Archrock common stockholders, after deducting amounts allocated 
to participating securities, by the weighted average number of common shares outstanding for the period. Participating 
securities include unvested restricted stock and stock-settled restricted stock units that have nonforfeitable rights to receive 
dividends or dividend equivalents, whether paid or unpaid. During periods of net loss, only distributed earnings (dividends) 
are  allocated to  participating  securities, as they  do not  have  a contractual  obligation  to  participate in our  undistributed 
losses. 

Diluted  net  income  (loss)  per  common  share  attributable  to  Archrock  common  stockholders  is  computed  using  the 
weighted  average  number  of  shares  outstanding  adjusted  for  the  incremental  common  stock  equivalents  attributed  to 
outstanding options, performance-based restricted stock units and stock to be issued pursuant to our ESPP unless their 
effect would be anti-dilutive. 

The following table shows the calculation for net income (loss) attributable to Archrock common stockholders, which is 
used  in  the  calculation  of  basic  and  diluted  net  income  (loss)  per  common  share  attributable  to  Archrock  common 
stockholders (in thousands):

We  are  exposed  to  market  risks  associated  with  changes  in  the  variable  interest  rate  of  our  Credit  Facility.  We  use 
derivative instruments to manage our exposure to fluctuations in this variable interest rate and thereby minimize the risks 
and  costs  associated  with  financial  activities.  We  do  not  use  derivative  instruments  for  trading  or  other  speculative 
purposes. 

As of December 31, 2020, we had $300.0 million notional value of interest rate swaps outstanding, which expire in March 
2022 and were entered into to offset changes in expected cash flows due to fluctuations in the associated variable interest 
rates. We have designated these interest rate swaps as cash flow hedging instruments. The counterparties to our derivative 
agreements are major financial institutions. We monitor the credit quality of these financial institutions and do not expect 
nonperformance by any counterparty, although such nonperformance could have a material adverse effect on us. We have 
no collateral posted for our derivative instruments. 

We expect the hedging relationship to be highly effective as the interest rate swap terms substantially coincide with the 
hedged item and are expected to offset changes in expected cash flows due to fluctuations in the variable rate. We estimate 
that  $4.8  million  of  the  deferred  pre-tax  loss  attributable  to  interest  rate  swaps  included  in  accumulated  other 
comprehensive  loss  at  December 31,  2020  will  be  reclassified  into  earnings  as  interest  expense  at  then-current  values 
during the next 12 months as the underlying hedged transactions occur. 

As of December 31, 2020, the weighted average effective fixed interest rate on our interest rate swaps was 1.8%.

See Note 2 (“Basis of Presentation and Significant Accounting Policies”), Note 15 (“Accumulated Other Comprehensive 
Income (Loss)”) and Note 23 (“Fair Value Measurements”) for further details on our derivative instruments. 

23. Fair Value Measurements 

The accounting standard for fair value measurements and disclosures establishes a fair value hierarchy that prioritizes the 
inputs of valuation techniques used to measure fair value into the following three categories: 

• (cid:1) Level 1 — Quoted unadjusted prices for identical instruments in active markets to which we have access at the 

date of measurement. 

• (cid:1) Level  2  —  Quoted  prices  for  similar  instruments  in  active  markets,  quoted  prices  for  identical  or  similar 
instruments  in  markets  that  are  not  active  and  model-derived  valuations  in  which  all  significant  inputs  and 
significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are 
few transactions, the prices are not current, little public information exists or prices vary substantially over time 
or among brokered market makers. 

• (cid:1) Level 3  —  Model-derived  valuations in  which one  or  more  significant inputs  or  significant value  drivers are 
unobservable.  Unobservable  inputs  are  those  inputs  that  reflect  our  own  assumptions  regarding  how  market 
participants would price the asset or liability based on the best available information. 

Assets and Liabilities Measured at Fair Value on a Recurring Basis 

On a quarterly basis, our interest rate swap derivative instruments are valued based on the income approach (discounted 
cash flow) using market observable inputs, including LIBOR forward curves. These fair value measurements are classified 
as Level 2. The following table presents our derivative asset and liability measured at fair value on a recurring basis, with 
pricing levels as of the date of valuation (in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis 

Goodwill 

In the first quarter of 2020, we determined that the significant deterioration in global macroeconomic conditions caused 
by the COVID-19 pandemic was an indicator of potential impairment of our goodwill, and we performed a quantitative 
impairment test as of March 31, 2020 that resulted in a $99.8 million impairment of our goodwill. Significant estimates 
used in our impairment analysis included cash flow forecasts, our estimate of the market’s weighted average cost of capital 
and market multiples, which are Level 3 inputs. See Note 9 (“Goodwill”) for further details of the valuation methodology 
used in connection with the goodwill impairment. 

Properties 

During the third  quarter  of  2020,  a  plan  to dispose of  certain  non-core  properties  was  approved  by  management. The 
properties not sold at auction were impaired and written down to fair value. The commercial real estate market where these 
properties are located is not an active market. Our estimate of fair value included inputs from offers received as well as 
market  transactions  for  similar  properties,  which  are  Level  3  inputs. The  fair  value  of  our  impaired  properties  was  as 
follows (in thousands): 

Impaired properties

The  significant  unobservable  inputs  used  to  develop  the  Level  3  fair  value  measurements  for  the  properties  were  the 
estimated  sale  values  in  an  inactive  market.  In  reviewing  sales  trends  for  the  past  three  years,  the  probable  pricing 
information based on market comparisons was as follows (in thousands): 

Estimated sale proceeds 

Range 
$100 - $600 

      Weighted Average

See Note 19 (“Restructuring Charges”) for further details of our approved plan of disposal. 

Compressors 

During the years ended December 31, 2020 and 2019, we recorded nonrecurring fair value measurements related to our 
idle and previously-culled compressors. Our estimate of the compressors’ fair value was primarily based on the expected 
net sale proceeds compared to other fleet units we recently sold and/or a review of other units recently offered for sale by 
third parties, or the estimated component value of the equipment we plan to use. We discounted the expected proceeds, 
net  of  selling  and  other  carrying  costs,  using  a  weighted  average  disposal  period  of  four years.  These  fair  value 
measurements  are  classified  as  Level  3.  The  fair  value  of  our  compressors  impaired  during  the  years  ended 
December 31, 2020 and 2019 was as follows:

value  of  the  compressors  being  measured.  Additional  quantitative  information  related  to  our  significant  unobservable 
inputs as of December 31, 2020 follows:

Other Financial Instruments

The carrying amounts of our cash, receivables and payables approximate fair value due to the short-term nature of those 
instruments. 

The  carrying  amount  of  borrowings  outstanding  under  our  Credit  Facility  approximates  fair  value  due  to  its  variable 
interest rate. The fair value of these outstanding borrowings is a Level 3 measurement.

The 2020 Plan was adopted in April 2020 and provides for the granting of stock options, restricted stock, restricted stock 
units,  stock  appreciation  rights,  performance  awards,  other  stock-based  awards  and  dividend  equivalent  rights  to 
employees, directors and consultants of Archrock. The 2020 Plan is administered by the compensation committee of our 
Board  of  Directors.  Under  the  2020  Plan,  the  maximum  number  of  shares  of  common  stock  available  for  issuance  is 
8,500,000. Each stock-settled award granted under the 2020 Plan reduces the number of shares available for issuance by 
one share. Cash-settled awards are not counted against the aggregate share limit. Shares subject to awards granted under 
the 2020 Plan that are subsequently canceled, terminated, settled in cash or forfeited, excluding shares withheld to satisfy 
tax withholding obligations or to pay the exercise price of an option, are available for future grant under the 2020 Plan. 
No additional grants may be made under the 2013 Plan following the adoption of the 2020 Plan. Previous grants made 
under the 2013 Plan continue to be governed by that plan and the applicable award agreements. 

The 2020 Plan and 2013 Plan allow us to withhold shares upon vesting of restricted stock at the then-current market price 
to cover taxes required to be withheld on the vesting date. During the years ended December 31, 2020, 2019 and 2018, we 
withheld 236,752 shares valued at $1.8 million, 212,080 shares valued at $2.0 million and 167,382 shares valued at $1.8 
million, respectively, to cover tax withholding.

The compensation committee of our Board of Directors generally establishes its schedule for making annual long-term 
incentive  awards,  consisting  of  a  combination  of  restricted  shares  and  performance  units  vesting  over  multiple years, 
several months  in  advance  and  does  not  make  such  awards  based  on  knowledge  of  material  nonpublic  information. 
Although the compensation committee of our Board of Directors has historically granted awards on a regular, predictable 
cycle, such awards may be granted at other times during the year, as determined in the sole discretion of the compensation 
committee.

Stock Options 

Stock options are granted at fair market value at the grant date, are exercisable according to the vesting schedule established 
by the compensation committee of our Board of Directors in its sole discretion and expire no later than seven years after 
the grant date. Stock options generally vest one-third per year on each of the first three anniversaries of the grant date, 
subject to continued service through the applicable vesting date. During the years ended December 31, 2020, 2019 and 
2018, we did not grant any stock options. Stock option activity during the year ended December 31, 2020 was as follows:

Intrinsic value is the difference between the market value of our stock and the exercise price of each stock option multiplied 
by the number of stock options outstanding for those stock options where the market value exceeds their exercise price. 
The total intrinsic value of stock options exercised during the year ended December 31, 2018 was $0.8 million. There were 
no  stock  options  exercised  during  the years  ended  December 31,  2020  and  2019.  Stock  options  outstanding  at 
December 31, 2020 expire in March 2021. 

Restricted  Stock,  Restricted  Stock  Units,  Performance-Based  Restricted  Stock  Units,  Cash-Settled  Restricted  Stock 
Units and Cash-Settled Performance Units 

For grants of restricted stock and restricted stock units, we recognize compensation expense over the vesting period equal 
to the fair value of our common stock at the grant date. Our restricted stock and restricted stock units include rights to 
receive dividends or dividend equivalents. We periodically remeasure the fair value of cash-settled restricted stock units 
and  cash-settled  performance  units  and  record  a  cumulative  adjustment  of  the  expense  previously  recognized.  Our 
obligation related to the cash-settled restricted stock units and cash-settled performance units is reflected as a liability in 
our consolidated balance sheets. Restricted stock, restricted stock units, cash-settled restricted stock units and cash-settled 
performance units generally vest one-third per year on dates as specified in the applicable award agreement, subject to 
continued service through the applicable vesting date.

We  also  grant  performance-based  restricted  stock  units,  which  in  addition  to  service  conditions,  have  a  market-based 
condition, which determines the number of restricted stock units and dividend equivalents earned. The market condition 
is based on our total shareholder return ranked against that of a predetermined peer group over a three-year performance 
period. The awards vest in their entirety on a date specified in the award agreement in the year following the conclusion 
of  the  performance  period.  The  fair  value  of  the  performance-based  restricted  stock  units,  incorporating  the  market 
condition, is estimated on the grant date using a Monte Carlo simulation model. Expected volatilities for us and each peer 
company utilized in the model are estimated using a historical period consistent with the awards’ remaining performance 
period as of the grant date. The risk-free interest rate is based on the yield on U.S. Treasury Separate Trading of Registered 
Interest and Principal Securities for a term consistent with the remaining performance period. The dividend yield used is 
0.0% to approximate accumulation of earnings.

The weighted average grant date fair value of shares granted during the years ended December 31, 2020, 2019 and 2018 was $9.37, $10.01 and 
$9.66, respectively.
The total fair value of all awards vested during the years ended December 31, 2020, 2019 and 2018 was $7.1 million, $9.0 million and $8.2 million, 
respectively. 

(3)(cid:1) Non-vested awards as of December 31, 2020 were comprised of 454,000 cash-settled restricted stock units and cash-settled performance units and 

1,992,000 restricted stock, stock-settled restricted stock units and stock-settled performance-based restricted stock units.

As of December 31, 2020, we expect $13.7 million of unrecognized compensation cost related to unvested restricted stock, 
stock-settled restricted stock units, performance units, cash-settled restricted stock units and cash-settled performance units 
to be recognized over the weighted-average period of 1.7 years. Cash paid upon vesting of cash-settled restricted stock 
units  during  the years  ended  December 31, 2020,  2019  and  2018  was  $0.5  million,  $1.3  million  and  $1.1  million, 
respectively. 

Employee Stock Purchase Plan 

Adopted  in  2017,  our  ESPP  provides  employees  with  an  opportunity  to  participate  in  our  long-term  performance  and 
success through the purchase of shares of common stock at a price that may be less than fair market value. Each quarter, 
eligible employees may elect to withhold a portion of their salary up to the lesser of $25,000 per year or 10% of their 
eligible pay to purchase shares of our common stock at a price equal to 85% to 100% of the fair market value of the stock 
as defined by the plan. The ESPP will terminate on the date that all shares of common stock authorized for sale under the 
ESPP have been purchased, unless it is extended. The maximum number of shares of common stock available for purchase 
under the ESPP is 1,000,000. As of December 31, 2020, 611,707 shares remained available for purchase under the ESPP. 
Our ESPP is compensatory and, as a result, we record an expense in our consolidated statements of operations related to 
the ESPP. The purchase discount under the ESPP is 5% of the fair market value of our common stock on the first trading 
day of the quarter or the last trading day of the quarter, whichever is lower.

Directors’ Stock and Deferral Plan 

Adopted in 2007, our DSDP provides non-employee members of the Board of Directors with an opportunity to elect to 
receive  our  common  stock  as  payment for  a  portion  or  all of their  retainer.  The  number  of  shares paid  each  quarter  is 
determined by dividing the dollar amount of fees elected to be paid in common stock by the closing sales price per share 
of the common stock on the last day of the quarter. In addition, directors who elect to receive a portion or all of their fees 
in the form of common stock may also elect to defer, until a later date, the receipt of a portion or all of their fees to be 
received in common stock. We have reserved 100,000 shares under the DSDP and, as of December 31, 2020, 37,771 shares 
remained available to be issued under the plan. 

25. Retirement Benefit Plan 

Our 401(k) retirement plan provides for optional employee contributions up to the applicable Internal Revenue Service 
annual limit and discretionary employer matching contributions. We make discretionary matching contributions to each 
participant’s account at a rate of 100% of each participant’s contributions up to 5% of eligible compensation. We recorded 
matching contributions of $5.6 million, $6.8 million and $6.5 million during the years ended December 31, 2020, 2019 
and 2018, respectively.

26. Commitments and Contingencies 

Performance Bonds 

In the normal course of business we have issued performance bonds to various state authorities that ensure payment of 
certain obligations. We have also issued a bond to protect our 401(k) retirement plan against losses caused by acts of fraud 
or dishonesty. The bonds have expiration dates in 2021 through the fourth quarter of 2022 and maximum potential future 
payments of $2.2 million. As of December 31, 2020, we were in compliance with all obligations to which the performance 
bonds pertain.

Tax Matters 

We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to audit 
by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional 
taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount 
of  the  liability.  As  of  December 31, 2020  and  2019,  we  accrued  $5.6  million  and  $2.5  million,  respectively,  for  the 
outcomes of non-income-based tax audits. We do not expect that the ultimate resolutions of these audits will result in a 
material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the 
assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably 
estimate the claim or range of the claim. We believe the likelihood is remote that the impact of potential unasserted claims 
from  non-income-based  tax  audits  could  be  material  to  our  consolidated  financial  position,  but  it  is  possible  that  the 
resolution of future audits could be material to our consolidated results of operations or cash flows. 

Subject  to  the  provisions  of  the  tax  matters  agreement  between  Exterran  Corporation  and  us,  both  parties  agreed  to 
indemnify  the  primary  obligor  of  any  return  for  tax  periods  beginning  before  and  ending  before  or  after  the  Spin-off 
(including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including 
interest and penalties) that relates to their respective operations reported in the filing. The tax contingencies mentioned 
above relate to tax matters for which we are responsible in managing the audit. As of December 31, 2020 and 2019, we 
had an indemnification liability (including penalties and interest), in addition to the tax contingency above, of $1.6 million 
and $2.8 million, respectively, for our share of non-income based tax contingencies related to audits being managed by 
Exterran Corporation. 

F-42 

Table of Contents

During the third quarter of 2020, we settled a certain sales and use tax audit for which we recorded a $12.4 million net 
benefit in our consolidated statements of operations. This net benefit was primarily reflected as decreases of $4.4 million 
and $7.9 million to cost of sales (excluding depreciation and amortization) and SG&A, respectively. We received a cash 
refund of $17.3 million in the fourth quarter of 2020 and have a $2.0 million accrued liability recorded as of December 
31, 2020 related to this settlement. 

Insurance Matters 

Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well 
fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry 
insurance  against  some,  but  not  all,  risks  of  our  business.  Our  insurance  coverage  includes  property  damage,  general 
liability and commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance 
coverage  is  customary  for  the  industry  and  adequate  for  our  business;  however,  losses  and  liabilities  not  covered  by 
insurance would increase our costs. 

Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of 
the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the 
deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. We are 
also self-insured for property damage to our offshore assets. 

Litigation and Claims 

In the ordinary course of business, we are involved in various pending or threatened legal actions. While we are unable to 
predict the ultimate outcome of these actions, we believe that any ultimate liability arising from any of these actions will 
not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our 
ability to pay dividends. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot 
provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material 
adverse  effect  on  our  consolidated  financial  position,  results  of  operations  or  cash  flows,  including  our  ability  to  pay 
dividends. 

27. Related Party Transactions 

In connection with the closing of the Elite Acquisition, we issued 21.7 million shares of our common stock to JDH Capital, 
an affiliate of our customer Hilcorp. As long as JDH Capital, together with affiliates of Hilcorp, owns at least 7.5% of our 
outstanding common stock, it will have the right to designate one director to our Board of Directors. Jeffery D. Hildebrand, 
founder and executive chairman of Hilcorp, was appointed Director in August 2019 and served until his resignation on 
July 29, 2020, at which time Jason C. Rebrook, President of Hilcorp, was appointed Director to fill the resulting vacancy. 
Mr.  Hildebrand  did  not  receive  and  Mr.  Rebrook  receives  no  compensation  for  their  role  as  Director.  As  of 
December 31, 2020, JDH Capital owned 14.2% of our outstanding common stock. 

Revenue  from  Hilcorp  and  affiliates  was  $40.3  million,  $31.4  million  and  $12.0  million  during  the years  ended 
December 31, 2020,  2019  and  2018,  respectively.  Accounts  receivable,  net  due  from  Hilcorp  and  affiliates  was  $3.9 
million and $5.1 million as of December 31, 2020 and 2019, respectively. 

28. Segments 

We manage our business segments primarily based on the type of product or service provided. We have two segments 
which we operate within the U.S.: contract operations and aftermarket services. The contract operations segment primarily 
provides  natural  gas  compression  services  to  meet  specific  customer  requirements.  The  aftermarket  services  segment 
provides a full range of services to support the compression needs of customers, from parts sales and normal maintenance 
services  to  full  operation  of  a customer’s  owned  assets.  We  evaluate  the performance  of  our  segments based  on  gross 
margin for each segment. Revenue includes only sales to external customers.

No  single  customer  accounted  for  10%  or  more  of  our  revenue  during  the years  ended  December 31,  2020  and  2019. 
During  the  year  ended  December  31,  2018,  Williams  Partners  accounted  for  11%  of  our  contract  operations  and 
aftermarket services revenue.

On  February  10,  2021,  we  completed  the  sale  of  certain  contract  operations  customer  service  agreements  and 
approximately  300  compressors,  comprising  approximately  40,000  horsepower,  used  to  provide  compression  services 
under those agreements as well as other assets used to support the operations. We allocated customer-related and contract-
based intangible assets based on a ratio of the horsepower sold relative to the total horsepower of the asset group. A gain 
on the sale of approximately $6.0 million will be recognized in the first quarter of 2021. 

Amendment No. 3 to Credit Facility 

On February 22, 2021, we amended our credit facility to, among other things: 

•(cid:1)
•(cid:1)

reduce the aggregate revolving commitment from $1.25 billion to $750.0 million, and 
increase the maximum Total Debt to EBITDA ratios and reduce the maximum Senior Secured Debt to EBITDA 
ratio, as defined in the credit facility agreement, to the following: 

Senior Secured Debt to EBITDA 
Total Debt to EBITDA 

Through fiscal year 2022 
January 1, 2023 through September 30, 2023

3.00 to 1.0 

5.75 to 1.0 
5.50 to 1.0 
5.25 to 1.0 

(1)(cid:1)

Subject to a temporary increase to 5.50 to 1.0 for any quarter during which an acquisition satisfying certain thresholds is completed and for the two 
quarters immediately following such quarter.

We incurred approximately $1.8 million in transaction costs related to Amendment No. 3 during the first quarter of 2021.
