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.  The  natural  gas  that  we  help  transport  satisfies  demand  from  electricity 
generation,  heating  and  cooking  and  the  industrial  and  manufacturing  sectors.  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. 

•  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 also critical to minimizing flaring and reducing the waste of natural gas and natural gas liquids 
that results from insufficient gathering and processing capacity. 

Compression  is  typically  required  throughout  the  natural  gas  production  and  transportation  cycle,  including  at  the 
wellhead,  throughout  gathering  and  distribution  systems,  into  and  out  of  processing  and  storage  facilities  and  along 
intrastate  and  interstate  pipelines.  Our  service  offerings  focus  primarily  on  midstream  applications,  with  77%  of  our 
operating fleet being used in the gathering and processing cycle stages. The remaining 23% of our operating fleet is used 
in gas lift applications. 

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. 

6 

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 help lift liquids to the surface, 
which is known as natural gas lift. 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. 

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: 

•  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 liquefied 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, 2021, 2020 and 2019, we generated 83%, 84% and 80%, respectively, of our total 
revenue from contract operations. 

7 

Compression Fleet 

The compressors that we own and use to provide contract operations services are predominantly large horsepower, which 
we define as greater than 1,000 horsepower per unit, and consist primarily of reciprocating compressors driven by natural 
gas-powered engines. Additionally, we provide a small but growing number of electric motor-driven compressors. Our 
fleet is largely standardized around major components and key suppliers, which minimizes our fleet operating costs and 
maintenance capital requirements, reduces inventory costs, facilitates low-cost compressor resizing and improves technical 
proficiency  in  our  maintenance  and  overhaul  operations,  which  in  turn  allows  us  to  achieve  higher  uptime  while 
maintaining lower operating costs.  

All of our compressors are designed to automatically  shut  down if operating conditions deviate from a pre-determined 
range and are also equipped with telematic devices that enable us to remotely monitor the units. We maintain field service 
locations from which our field technicians service and overhaul our fleet. Our equipment undergoes routine and preventive 
maintenance in accordance with our established maintenance schedules, standards and procedures, which we update as 
technology changes and as our operations group develops new techniques and procedures to better service our equipment. 
In  our  experience,  these  maintenance  practices  maximize  equipment  life  and  unit  availability,  minimize  emissions, 
minimize avoidable downtime and reduce the overall maintenance expenditures over the equipment life. As of December 
31, 2021, the average age of our operating fleet was 11 years.

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  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,  and  are  required  to  pay  a 
reduced monthly  fee  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 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, 2021, 2020 and 2019, we generated 17%, 16% and 
20%, 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, 2021, 80% 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. We guarantee our customers 98% availability 
in all of our contract operations service agreements, and during the year ended December 31, 2021, our availability was 
99.3%. 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 2021 total recordable incident rate of 0.10.  

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 400 customers operating 
throughout all major U.S. natural gas and crude oil producing regions. 

9 

Fee-based cash flows. We charge a fixed  monthly  fee  for our  contract operations  services and  a  reduced monthly fee 
during periods of limited or disrupted natural gas flows. 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. 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. 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 give us more flexibility in meeting our customers’ needs than many of our competitors and 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 industry and 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. 

Technology Transformation. As of the end of 2021, we had completed several major phases of a process and technology 
transformation project that enables us to harness technology in all aspects of our business to drive operational efficiencies 
and  enhance  our  value  proposition  to  our  customers.  Our  investments  have  focused  on  the  automation  of  workflows, 
integration of digital and mobile tools for our field service technicians and expanded remote monitoring capabilities of our 
vehicle  and  compressor  fleets.  We  expect  this  project  to,  among  other  things,  help  us  achieve  increased  asset  uptime, 
improve the efficiency of our field service technicians, improve our supply chain and inventory management and reduce 
our emissions and carbon footprint, thereby improving our profitability as discussed further below in “Business Strategies.” 

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 liquefied natural gas exports, exports of natural gas via pipeline to Mexico, 
power generation and industrial uses. 

10 

Improve profitability. We are focused on increasing productivity and optimizing our processes. As of the end of 2021, we 
had completed several major phases of a process and technology transformation project that replaced our existing ERP, 
supply chain and inventory management systems and expanded 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. Implementing telematics and advanced data analysis across our fleet will enable us to 
respond more quickly and optimally to downtime events, minimize prolonged troubleshooting, prevent unnecessary unit 
touches and stops, which are the primary cause of wear and tear of the equipment, and, ultimately, predict failures before 
they occur. We expect this will increase the number of units a field service technician can oversee and also reduce vehicle 
miles traveled and fuel consumption, thereby also reducing emissions. 

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. As part of this strategy, we sold 147,000 and 74,000 non-core horsepower during the years ended December 31, 
2021 and 2020, respectively, which drove an increase in our large operating horsepower from 74% of our fleet as of year 
end 2019, to 80% as of December 31, 2021.  

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 profitably 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: 

•  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; 

•  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  for  our  contract  operations  services  or  a 
reduced monthly fee during periods of limited or disrupted natural gas flows. 

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. 

11 

We  have  pricing  agreements  in  place  with  all  of  our  primary  suppliers  of  compression  equipment,  parts  and  services, 
including  Ariel,  Waukesha  and  Caterpillar  and  its  distributors,  and  work  closely  with  these  key  suppliers  on  value 
engineering,  to  lower  total  lifecycle  cost  and  improve  equipment  reliability.  Though  we  rely  on  these  suppliers  to  a 
significant degree, we believe alternative sources for compression equipment, parts and services are generally available. 

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, 2021,  2020  and  2019,  our  five  most  significant  customers 
collectively accounted for 31%, 28% and 25%, 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, 2021, 2020 and 2019. 

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 with low barriers to entry. 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. See “Competitive Strengths” above for further discussion. 

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,  health  and  safety  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. 

12 

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. In June 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.  

While the EPA in 2020 adopted deregulatory amendments  to the 2016 rule that  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, that 2020 rulemaking was voided by action of Congress and the President effective June 30, 2021. 
As  a  result,  the  2016  rules  became  effective  again  immediately.  Further,  in  November  2021,  the  EPA  proposed  the 
framework for more stringent methane rules for newer sources, along with emissions standards that will for the first time 
be applicable to existing sources. The actual proposed rule language is expected to be published in early 2022, and a final 
rule likely in the second half of 2022, following a public notice and comment period. The current administration and the 
EPA have indicated that additional rule proposals on oil and gas-related methane emissions are in the works.   

Meanwhile, several states — including, most notably, New Mexico and Colorado — have been developing their own more 
stringent  methane rules that  will or are anticipated  to impose additional requirements on the  industry and that  may be 
effective sooner than any new EPA rules. We, together with a consortium of other Gas Compressor Association member 
companies,  were actively  involved in the  rulemaking effort  in  New  Mexico,  including  working directly  with the  New 
Mexico Environmental Department and participating in the New Mexico Environmental Improvement Board’s hearing in 
late 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 definitively predict the impact of any revision of the current rules or issuance 
of new rules, which impact could be material. 

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. Those decisions have been subject to judicial challenge. In October 2021, the EPA revealed 
in court filings that it will revisit the December 2020 decision to retain the existing ozone standard. 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 or of the possible reconsideration and issuance of new NAAQS standards. 

13 

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.  Notably,  opposition  to  energy  development  and  infrastructure  projects  has  led  to  regulatory  and  judicial 
challenges to new facilities, including compression facilities, in states such as Massachusetts and Virginia. While we have 
not directly faced any such challenges to the facilities at which we provide contract operations and know of no pending or 
threatened efforts targeting those facilities, expanded opposition to energy infrastructure, including facilities at which we 
provide contract operations, could potentially give rise to material impacts in the future. 

Climate Change 

Climate change legislation and regulatory initiatives may arise 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.  

Congress has previously considered legislation to restrict or regulate emissions of greenhouse gases. 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 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 $1 
trillion legislative infrastructure package passed by Congress in November 2021 includes a number of climate-focused 
spending  initiatives  targeted  at  climate  resilience,  enhanced  response  and  preparation  for  extreme  weather  events,  and 
clean energy and transportation investments. Significant additional legislative proposals are also under consideration in 
Congress  in  early  2022  that  reportedly  could  provide  significant  funding  for  research  and  development  of  low-carbon 
energy production methods, carbon capture, and other programs directed at addressing climate change. 

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. In 2021, we did not operate any facilities that were subject to these 
reporting  obligations.  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.  As  noted  above,  the  EPA  has  undertaken  efforts  to  regulate  emissions  of  methane, 
considered a greenhouse gas, in the oil and gas sector, with the development of additional, more stringent rules under way. 

In an executive order issued on January 20, 2021, the POTUS 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. 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.” The current administration adopted an 
interim social cost of carbon of $51 per ton in February 2021, with an updated cost figure expected early in 2022. That 
figure is intended to be used to guide federal decisions on the costs and benefits of various policies and approvals, although 
such  efforts  have  been  the  subject  of  a  series  of  judicial  challenges.  At  this  time,  we  cannot  determine  whether  the 
administration’s efforts on social cost or other interagency climate efforts will lead to any particular actions that give rise 
to a material adverse effect on our business, financial condition, results of operations and cash flows. 

14 

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. In April 2021, the current administration announced 
reentry of the U.S. into the Paris Agreement along with a new “nationally determined contribution” for U.S. greenhouse 
gas emissions that would achieve emissions reductions of at least 50% relative to 2005 levels by 2030. Those national 
commitments by themselves create no binding requirements on individual companies or facilities, but they do provide 
indications of the current administration’s policy direction and the types of legislative and regulatory requirements—such 
as  the  EPA’s  proposed  methane  rules—that  may  be  needed  to  achieve  those  commitments.  Relatedly,  the  U.S.  and 
European Union jointly announced the launch of the “Global Methane Pledge,” which aims to cut global methane pollution 
at least 30% by 2030 relative to 2020 levels, including “all feasible reductions” in the energy sector. With the exception 
of  those  proposed  EPA  methane  rules,  which  were  announced  by  the  POTUS  at  the  United  Nations  Climate  Change 
Conference in Glasgow in November 2021, we cannot predict whether re-entry into the Paris Agreement or pledges made 
in connection therewith will result in any particular new regulatory requirements or whether such requirements will cause 
us to incur material costs. 

Although it is not currently possible to predict how these executive orders, national commitments or any proposed or future 
greenhouse gas or climate change 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. 

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. The definition of “waters of the United States” and, relatedly, the scope of CWA jurisdiction, have been 
the subject of notable rulemaking efforts and judicial challenges over several decades. As a result of judicial and regulatory 
action, different approaches to the definitions adopted in 2015 and in 2020 by the EPA and the Army Corps of Engineers 
were stayed or vacated during 2021, with the effect of restoring to effectiveness rules and guidance from the mid-1980s.  
In  the  meantime,  the  current  administration  is  developing  new  rules  intended  to  provide  a  legally  durable  definition 
designed to clarify and stabilize the scope of the agencies’ jurisdiction. In January 2022, the U.S. Supreme Court agreed 
to take up the issue of the appropriate scope of CWA jurisdiction.

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 POTUS 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. The widespread availability 
of  COVID-19  vaccines  and  apparent  improvements  in  health  outcomes  present  important  opportunities  for  the  safe 
operation of our business. 

16 

On November 5, 2021, OSHA issued an Emergency Temporary Standard requiring most employers of over 100 employees 
to  require  workers  to  be  vaccinated  or  to  wear  masks  and  be  tested  weekly.  However,  on  January  13,  2022,  the  U.S. 
Supreme Court granted emergency relief staying the implementation of that OSHA standard pending further review in the 
lower courts. The current administration has announced that it will continue to urge employers to take steps to safeguard 
worker health and will use its existing authorities to hold businesses accountable for doing so. Additionally, there is the 
possibility  that  individual  states  may  implement  “vaccinate  or  test”  requirements  similar  to  the  stayed  OSHA 
standard. While we have robust measures in place that meet or exceed current applicable requirements with respect to the 
COVID-19  pandemic,  at  this  time  we  do  not  know  if  or  how  any  additional  developments  with  the  pandemic,  or  any 
regulatory initiatives adopted in response to it, will affect our operations. We will continue to monitor and act in accordance 
with applicable law and in the best interests of our employees and those with whom we interact. 

Human Capital 

As of December 31, 2021, we had approximately 1,100 employees and had a presence in 41 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, as is reflected in the diversity of our Board of Directors, of which three of nine directors are gender or 
ethnically diverse. Similarly, one third of our executive leadership team is female and 40% of our total workforce is gender 
or ethnically diverse. 

We support gender and ethnic pay equity and 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 continuously 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  15  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 have successfully lowered our total recordable incident rate from 0.54 in 2019, 
to 0.25 in 2020, and to 0.10 in 2021, 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. 

17 

Response to COVID-19 Pandemic 

Beginning  in  2020,  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. Office occupancy in 
2021 varied based on conditions in the local area. Since the start of the pandemic, we have 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 27,000 hours of operational and 
technical training during 2021. 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 2021 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  may  continue  to  negatively  affect  demand  for  our  services,  and  may  continue  to  have  a 
material adverse impact on our financial condition, results of operations and cash flows. 

COVID-19 continues to impact public  health,  economic growth, supply chains and  markets.  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 continue to closely  monitor 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 agreements 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. 

19 

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

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, 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. As of December 31, 
2021, JDH Capital owned 11.1% of our outstanding common stock. 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, 2021, 
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, 2021. 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: 

•  the availability of surplus or net profits, which in turn depend on the performance of our business and operating 

subsidiaries; 

20 

•  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, 2021,  we  had  $1.5  billion  in  outstanding  debt  obligations,  net  of  unamortized  debt  premiums  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; 
•  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. 

21 

Our Credit Facility is also subject to financial covenants, including the following ratios, 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)  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 our 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, 2021, 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. 

22 

 
 
 
 
     
  
  
   
  
 
  
 
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. 

After  taking  into  consideration  interest  rate  swaps,  we  did  not  have  any  outstanding  indebtedness  that  was  subject  to 
variable interest rates as of December 31, 2021. However, our interest rate swaps mature in the first quarter of 2022, at 
which  time  all  borrowings  under  our  Credit  Facility  will  be  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. 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 phasing out of LIBOR may adversely affect the market value of our current or future debt 
obligations, including our Credit Facility. 

On May 3, 2021, the FCA announced that certain U.S. dollar LIBOR rates, including the 1-month rate used to determine 
the amount of interest payable related to borrowings under our Credit Facility, will cease to be provided after June 30, 
2023.  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. Our Credit Facility agreement requires that we execute an amendment that establishes an alternate 
reference rate should the 1-month U.S. dollar LIBOR cease to be published, to be agreed upon by us and the lenders under 
the facility. The alternate reference rate selected 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 or future debt obligations, including the 
Credit Facility, if U.S. dollar LIBOR was available in its current form. Replacement of the 1-month U.S. dollar LIBOR 
may, therefore, 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.  

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. 

23 

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 31%, 28% and 25% of our revenue for the years ended 
December 31, 2021,  2020  and  2019,  respectively.  Our  services  are  provided  to  these  customers  pursuant  to  contract 
operations  service  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 service agreements 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  service  agreements  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. In addition, the cost of labor has 
increased and may continue to increase in the future with increases in demand, which could require us to incur additional 
costs and negatively impact our results of operations. 

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.  

24 

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.  Further,  supply  chain  bottlenecks  resulting  from  the  COVID-19  pandemic  could 
adversely affect our ability to obtain necessary materials, parts or lube oil used in our operations or increase the costs of 
such items. A significant increase in the price of such equipment,  materials and services, as a result of the COVID-19 
pandemic or otherwise, could have a negative impact on our business, results of operations, financial condition and cash 
flows. 

Information Technology and Cybersecurity Risks 

We may not realize the intended benefits of our process and 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, which has, among other things, 
replaced  our  existing  ERP,  supply  chain  and  inventory  management  systems  and  expanded  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  process  and 
technology transformation project has required significant capital and other resources from which we may not realize the 
benefits we expect to realize. 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 may 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. 

25 

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 experience 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. 

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. 

26 

On January 27, 2021, the POTUS 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.  Some  legal  challenges  to  the  suspension  have  been  successful  and  the  current 
administration has resumed leasing activities, although there are substantial indications that future leasing activities will 
involve more stringent environmental conditions.  

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. 

While we cannot predict the ultimate outcome of such recent developments, 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. 

In June 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. 

While the EPA in  2020 adopted deregulatory  amendments  to  the 2016 rule that  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, that 2020 rulemaking was voided by action of Congress and the President effective June 30, 2021. 
As  a  result,  the  2016  rules  became  effective  again  immediately.  Further,  in  November  2021,  the  EPA  proposed  the 
framework for more stringent methane rules for newer sources, along with emissions standards that will for the first time 
be applicable to existing sources. The actual proposed rule language is expected to be published in early 2022, and a final 
rule likely in the second half of 2022, following a public notice and comment period. The current administration and the 
EPA have indicated that additional rule proposals on oil and gas-related methane emissions are in the works.   

Meanwhile, several states—including, most notably, New Mexico and Colorado—have been developing their own more 
stringent  methane rules that  will or are anticipated  to  impose  additional  requirements  on the  industry and that  may be 
effective sooner than any new EPA rules. We, together with a consortium of other Gas Compressor Association member 
companies,  were actively  involved in the  rulemaking effort in  New  Mexico,  including  working directly  with the  New 
Mexico Environmental Department and participating in the New Mexico Environmental Improvement Board’s hearing in 
late 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 definitively predict the impact of any revision of the current rules or issuance 
of new rules, which impact could be material. 

27 

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.  Those 
decisions have been subject to judicial challenge. In October 2021, the EPA revealed in court filings that it will revisit the 
December 2020 decision to retain the existing ozone standard. 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 or of the possible reconsideration 
and issuance of new NAAQS standards. 

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. 
Notably, opposition to energy development and infrastructure projects has led to regulatory and judicial challenges to new 
facilities, including compression facilities, in states such as Massachusetts and Virginia. While we have not directly faced 
any such challenges to the facilities at which we provide contract operations and know of no pending or threatened efforts 
targeting those facilities, expanded opposition to energy infrastructure, including facilities at which we provide contract 
operations, could potentially give rise to material impacts in the future. 

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.  Notably,  the  current  administration  has 
indicated an intention to expand environmental enforcement efforts, and that it plans to target for enhanced enforcement 
locations  and  violations  that  involve  harm  to  minority  and  low-income  communities  that  historically  have  faced 
disproportionate environmental burdens. 

28 

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 arise 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.  

Congress has previously considered legislation to restrict or regulate emissions of greenhouse gases. 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 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 $1 
trillion legislative infrastructure package passed by Congress in November 2021 includes a number of climate-focused 
spending  initiatives  targeted  at  climate  resilience,  enhanced  response  and  preparation  for  extreme  weather  events,  and 
clean energy and transportation investments. Significant additional legislative proposals are also under consideration in 
Congress  in  early  2022  that  reportedly  could  provide  significant  funding  for  research  and  development  of  low-carbon 
energy production methods, carbon capture, and other programs directed at addressing climate change. 

29 

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. In 2021, we did not operate any facilities that were subject to these 
reporting  obligations.  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.  As  noted  above,  the  EPA  has  undertaken  efforts  to  regulate  emissions  of  methane, 
considered a greenhouse gas, in the oil and gas sector, with the development of additional, more stringent rules under way. 

In an executive order issued on January 20, 2021, the POTUS 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. 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.” The current administration adopted an 
interim social cost of carbon of $51 per ton in February 2021, with an updated cost figure expected early in 2022. That 
figure is intended to be used to guide federal decisions on the costs and benefits of various policies and approvals, although 
such  efforts  have  been  the  subject  of  a  series  of  judicial  challenges.  At  this  time,  we  cannot  determine  whether  the 
administration’s efforts on social cost or other interagency climate efforts will lead to any particular actions that give rise 
to a material adverse effect on our business, financial condition, results of operations and cash flows. 

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. In April 2021, the current administration announced 
reentry of the U.S. into the Paris Agreement along with a new “nationally determined contribution” for U.S. greenhouse 
gas emissions that would achieve emissions reductions of at least 50% relative to 2005 levels by 2030. Those national 
commitments by themselves create no binding requirements on individual companies or facilities, but they do provide 
indications of the current administration’s policy direction and the types of legislative and regulatory requirements—such 
as  the  EPA’s  proposed  methane  rules—that  may  be  needed  to  achieve  those  commitments.  Relatedly,  the  U.S.  and 
European Union jointly announced the launch of the “Global Methane Pledge,” which aims to cut global methane pollution 
at least 30% by 2030 relative to 2020 levels, including “all feasible reductions” in the energy sector. With the exception 
of  those  proposed  EPA  methane  rules,  which  were  announced  by  the  POTUS  at  the  United  Nations  Climate  Change 
Conference in Glasgow in November 2021, we cannot predict whether re-entry into the Paris Agreement or pledges made 
in connection therewith will result in any particular new regulatory requirements or whether such requirements will cause 
us to incur material costs. 

Although it is not currently possible to predict how these executive orders, national commitments or any proposed or future 
greenhouse gas or climate change 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. 

30 

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. 

31 

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.

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 2021 Form 10-K. 

This section primarily discusses 2021 and 2020 items and comparisons between these years. For a discussion of changes 
from 2019 to 2020 and other financial information related to 2019, refer to Part II Item 7 “Management’s Discussion and 
Analysis  of  Financial  Condition  and  Results  of  Operations”  of  our  Annual  Report  on  Form  10-K  for  the  year  ended 
December 31, 2020 filed with the SEC on February 23, 2021. 

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., 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.  The  natural  gas  that  we  help  transport  satisfies  demand  from  electricity 
generation,  heating  and  cooking  and  the  industrial  and  manufacturing  sectors.  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 compression operations services to our customers. 

•  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. 

Significant 2021 Transactions 

July 2021 Dispositions 

In  July  2021,  we  completed  sales  of  certain  contract  operations  customer  service  agreements  and  approximately  575 
compressors,  comprising  approximately  100,000  horsepower,  used  to  provide  compression  services  under  those 
agreements, as well as other assets used to support the operations. We received cash consideration of $60.3 million for the 
sales and recorded gains on the sales of $13.0 million during the year ended December 31, 2021. The proceeds received 
from the sales were used to repay borrowings outstanding under our Credit Facility. See Note 4 (“Business Transactions”) 
to our Financial Statements for further details of these transactions. 

February 2021 Disposition 

In February 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 recorded a gain on the sale of $6.0 million during 
the year ended December 31, 2021. See Note 4 (“Business Transactions”) to our Financial Statements for further details 
of this transaction. 

36 

 
Amendment No. 3 to our Credit Facility 

In February 2021, we amended our Credit Facility to, among other things, reduce the aggregate revolving commitment 
from $1.25 billion to $750.0 million and adjust the maximum Senior Secured Debt to EBITDA and Total Debt to EBITDA 
ratios. We incurred $1.8 million in transaction costs and wrote off $4.9 million of unamortized deferred financing costs as 
a result of Amendment No. 3. See Note 14 (“Long-Term  Debt”) to our Financial Statements  for further details of this 
amendment. 

At-the-Market Continuous Equity Offering Program 

In February 2021, we entered into an ATM Agreement whereby we may sell, from time to time, shares of our common 
stock for an aggregate offering price of up to $50.0 million. We use the proceeds of these offerings for general corporate 
purposes. During the year ended December 31, 2021, we sold 357,148 shares of common stock for net proceeds of $3.4 
million pursuant to this agreement. See Note 16 (“Equity”) to our Financial Statements for further details of this agreement. 

Trends and Outlook 

The key driver of our business is the production of U.S. natural gas and crude oil. Approximately 77% of our operating 
fleet  is  deployed  for  midstream  natural  gas  gathering  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 

Beginning  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  adversely  impacted  our  revenue  and  cash  flows.  Though  demand  and  commodity  prices  have  shown 
improvement since the lows reached in the second quarter of 2020, the potential for additional surges and variants of the 
disease remains and as such, uncertainty still exists around the timing and potential for a full economic recovery. 

Our customers substantially cut spending and activity beginning in the second quarter of 2020 as a result of the significant 
declines  in  natural  gas  and  crude  oil  prices  and  demand  and  consequently,  our  horsepower,  utilization  and  revenue 
experienced  declines  and  remained  at  lower  levels  in  2021,  as  compared  to  early  2020  and  periods  prior,  in  both  our 
contract operations and aftermarket services businesses. In addition to the decline in revenue, the impact of the COVID-
19 pandemic on our results is primarily visible in the $99.8 million non-cash impairment of goodwill and the impairment’s 
resulting $22.7 million tax benefit in the first quarter of 2020. Cost of sales, SG&A, 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.

Current Trends 

In 2019, increased global demand for U.S. natural gas and crude oil production contributed to increased production for 
both resources and record U.S. natural gas production. Production fell sharply, however, in the second quarter of 2020 as 
a result of the global response to the COVID-19 pandemic, and remained at depressed levels until the latter half of 2021, 
at which point production rose relatively consistently through the remainder of the year. According to the EIA’s February 
2022 Short-Term Energy Outlook, average U.S. dry natural gas and crude oil production in 2021, 2020 and 2019 were as 
follows: 

Year Ended December 31,  
2020 

2021 

2019 

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

 93.6    
 11.2    

 91.3    
 11.3    

 92.0 
 12.2 

The increases in production in 2019 resulted in strong demand for our compression services in that year and into the first 
quarter of 2020. Additionally, we increased our investment in new fleet units in 2019 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. In  2020,  however,  the decrease in demand  and  production 
brought on by the COVID-19 pandemic drove revenue and average operating horsepower to below 2019 levels, where 
they remained through all of 2021, as producers limited drilling and completion activity to achieve maintenance levels of 
production and cash flows in the course of the pandemic. 

Similar  decreases  in  demand  as  a  result  of  the  pandemic  were  seen  in  our  aftermarket  services  business,  where  we 
experienced  a  rise  in  customer  deferrals  of  maintenance  activities  throughout  2020  and  the  beginning  of  2021,  before 
demand picked up in the second quarter of 2021 and continued to improve through the remainder of the year. 

Outlook 

The EIA forecasts the following year-over-year changes in its February 2022 Short-Term Energy Outlook: 

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

Increase (Decrease) 

2022 

2023 

 3  %    
 7  %    
 2  %   
 16  %    

 2  % 
 5  % 
 (1)% 
 7  % 

Overall, natural gas and crude oil production is expected to increase in 2022 and 2023, returning to pre-COVID-19 levels 
in  2023,  as  U.S. onshore  activity  continues  the  rise  it  began  in  mid-2021.  Accordingly,  we  anticipate  demand  for  our 
compression services to also increase as we move into 2022. 

Longer term, per the EIA’s 2021 Annual Energy Outlook, the EIA expects dry natural gas production to increase 12%, 
17% and 33% through 2025, 2030 and 2050, 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. 

Regarding  our  aftermarket  services  business,  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  –  those  caused  by  the  COVID-19  pandemic  and 
otherwise – 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 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 2022 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 significantly reduce our annual operating, corporate and capital costs, 
many aspects of which we continued to execute on throughout 2021 and expect to continue in the foreseeable future. In 
addition, in order to improve our operations and further reduce operating expenses, we are investing significant resources 
into a process and technology transformation project that has, among other things, replaced our existing ERP, supply chain 
and  inventory  management  systems  and  expanded  the  remote  monitoring  capabilities  of  our  compression  fleet.  Cost 
management continues to be challenging, however, 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 in full, could 
cause us to experience increased operating expenses as we hire employees and incur additional expenses needed to support 
the rebound in market demand. 

Further, we depend on suppliers for the materials, parts, equipment and lube oil necessary to our operations, which exposes 
us to volatility in prices. Significant price increases for these inputs could adversely affect our operating profits. Supply 
chain bottlenecks resulting from the COVID-19 pandemic could also adversely affect our ability to obtain, or increase the 
cost of, such items. While we generally attempt to mitigate the impact of increased prices through strategic purchasing 
decisions, diversification of our supplier base, where possible, and the passing along of increased costs to customers, there 
may be a time delay between the increased commodity prices and the ability to increase the price of our services. 

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. Further, the cost of labor has increased and may continue to 
increase in the future with increases in demand, which will require us to incur additional costs. 

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 10% in 2019, decreased 1% in 2020, increased 
3% in 2021, and is expected to increase 12% in 2022 through 2025. We believe that, similar to the rapid drops in customer 
demand and associated revenue experienced  in  2020, our revenue  will  increase closely  behind  the  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 saw a decrease in these deferrals beginning in the second quarter of 2021, and we believe the 
large installed base of owned compression in the U.S. supports the long-term fundamentals of the aftermarket services 
business, however, the timing of a full 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 modest natural gas production growth rate, to which demand for our products and services is closely aligned. 

Demand for natural gas-powered compression. Demand for our services is dependent on the demand for natural gas in 
the markets we serve. Although the EIA currently forecasts natural gas demand will grow through 2050, technological 
advances and accelerated adoption of renewable sources of energy could reduce demand for natural gas in our markets 
and have an adverse effect on our business. In addition, increased focus of our customers on reducing emissions from, or 
the use of, combustion engines in compression could increase demand for electric motor-driven compressors or require us 
to make modifications to our existing natural gas-powered units.

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) expense, 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.

Revenue was $781.5 million and $875.0 million during the years ended December 31, 2021 and 2020, respectively. The 
decrease in revenue was due to declines in revenue from both our contract operations and aftermarket services businesses. 
See “Contract Operations” and “Aftermarket Services” below for further details. 

Net Income (Loss) 

We had net income of $28.2 million and a net loss of $68.4 million during the years ended December 31, 2021 and 2020, 
respectively.  The  change  from  net  loss  in  2020  to  net  income  in  2021  was  primarily  driven  by  decreases  in  goodwill 
impairment,  long-lived  and  other  asset  impairment,  depreciation  and  amortization,  restructuring  charges  and  debt 
extinguishment loss, as well as increases in gain on sale of assets, net and other income, net. These changes were partially 
offset by decreases in gross margin of our contract operations and aftermarket services businesses and the change from a 
benefit from to a provision for income taxes.

Revenue decreased primarily due to returns of horsepower amidst the market downturn that began in early 2020, as well 
as the strategic disposition of horsepower in 2020 and 2021. 

Gross margin decreased due to the decrease in revenue, however, the decline was partially mitigated by the decrease in 
cost of sales. The lower operating horsepower discussed above drove a decrease in maintenance, freight and other operating 
expenses. Offsetting these decreases were (i) increases in start-up and other operating expense, which resulted from an 
increase in unit redeployment as customers returned to operations from standby status, and lube oil expense, which was 
primarily  due  to  an  increase  in  commodity  price  and  increased  volumes  associated  with  unit  redeployment,  and  (ii)  a 
decrease in our sales and use tax benefit, which resulted from audit settlements in 2020 and no comparable settlements in 
2021.

Revenue decreased by $5.2 million due to the sale of our turbocharger business in July 2020, and was further reduced by 
a  decrease  in  service  activities,  which  was  primarily  driven  by  customer  deferral  of  maintenance  activities  amidst  the 
market  downturn.  These  decreases  were  partially  offset  by  an  increase  in  parts  sales  that  resulted  from  an  increase  in 
customer demand in the second half of 2021. 

Gross margin decreased due to the decrease in revenue, however, the decline was partially mitigated by the decrease in 
cost of sales. The decrease in cost of sales was driven by the decrease in service activities and the sale of our turbocharger 
business. These decreases to costs of sales were partially offset by the increase in parts sales.

Selling, general and administrative. The increase in SG&A was primarily due to a $4.1 million increase in sales and use 
tax that was mainly driven by audit settlements in 2020 and no comparable settlements in 2021, a $1.3 million increase in 
information technology expenses, which largely consisted of costs related to our process and technology transformation 
project,  and  a  $0.8  million  increase  in  professional  expenses.  These  increases  were  partially  offset  by  a  $3.6  million 
decrease in our provision for credit losses and a $1.4 million decrease in compensation and benefits. 

Depreciation  and  amortization.  The  decrease  in  depreciation  and  amortization  was  primarily  due  to  a  decrease  in 
depreciation expense resulting from assets reaching the end of their depreciable lives, the impact of compression and other 
asset impairments and sales and a decrease in amortization expense as certain intangible assets reached the end of their 
useful lives. These decreases were partially offset by increases in depreciation expense associated with fixed asset additions 
and the write-off of compression and building assets damaged by Hurricane Ida in 2021. 

Long-lived and other asset impairment. We periodically 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:

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

Goodwill impairment. During the year ended December 31, 2020, we recorded goodwill impairment of $99.8 million 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. Restructuring charges of $2.9 million and $8.5 million during the years ended December 31, 2021 
and 2020, respectively, primarily consisted of severance and property disposal costs related to our restructuring activities. 
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  weighted  average  effective 
interest rate and the $4.9 million write-off of unamortized deferred financing costs related to Amendment No. 3, which 
were largely offset by a decrease in the average outstanding balance of long-term debt. 

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

Gain on sale of assets, net. Our net gain on the sale of assets during the year ended December 31, 2021 was primarily the 
result of $13.0 million of gains recognized on the July 2021 Dispositions, the $6.0 million gain on the February 2021 
Disposition,  $9.3  million  of  gains  recognized  on  other  compression  asset  sales  during  2021  and  $3.3  million  of  gains 
recognized on other transportation and shop asset sales during the period. 

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

Other income, net. The increase in other income, net was primarily due to an insurance settlement of $2.8 million related 
to damages caused by Hurricane Ida to facilities and compressors, as well as a $0.4 million decrease in indemnification 
expense remitted pursuant to our tax matters agreement with Exterran Corporation.

Liquidity and Capital 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  our  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 caused a deterioration 
in global macroeconomic conditions, which adversely 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.

Cash 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: 

•  operating expenses, namely employee compensation and benefits and inventory and lube oil purchases; 
•  growth capital expenditures; 
•  maintenance capital expenditures; 
•  interest on our outstanding debt obligations; and 
•  dividend payments to our stockholders. 

Capital Expenditures 

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 that exceed our cost of capital over the compressor’s expected useful 
life. 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 $37.2 million and $79.1 million during the years ended December 31, 2021 and 2020, 
respectively.  The  decrease  in  growth  capital  expenditures  from  2020  to  2021  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 further reductions in spend in response to the decreased customer demand that resulted from the COVID-19 pandemic. 

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 $47.3 million and $32.0 million during the years ended December 31, 2021 and 
2020, respectively. The increase in maintenance capital expenditures from 2020 to 2021 was the result of an increase in 
scheduled maintenance activities due to maintenance cycle requirements as well as additional make-ready investment as 
we return idle equipment to work to meet customer demand. 

Projected  Capital  Expenditures.  We  currently  plan  to  spend  approximately  $213  million  to  $235  million  in  capital 
expenditures  during  2022,  primarily  consisting  of  approximately  $150  million  for  growth  capital  expenditures 
and approximately $55 million to $75 million for maintenance capital expenditures. We anticipate increased 2022 capital 
expenditures,  particularly  growth  capital  expenditures,  as  compared  to  2021  due  to  increased  investment  in  new 
compression equipment as a result of higher customer demand. 

Dividends 

On  January 27,  2022,  our  Board  of  Directors  declared  a  quarterly  dividend  of  $0.145  per  share  of  common  stock,  or 
approximately $22.6 million, which was paid on February 15, 2022 to stockholders of record at the close of business on 
February 8, 2022. 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. 

45 

Contractual Obligations 

Our material contractual obligations as of December 31, 2021 consisted of the following: 

•  Long-term debt of $1.5 billion, of which $1.3 billion is due in 2027 and 2028, with the remainder due in 2024; 
•  Estimated interest on our long-term debt of $515 million, consisting of approximate annual payments of $90 million 

in 2021 through 2024 and annual payments of $85 million or less in 2025 through 2028; 

•  Purchase  commitments  of  $95.5  million,  of  which  $89.2  million  is  due  in  2022,  that  primarily  consist  of 

commitments to purchase fleet assets and information technology-related costs; and 

•  Operating lease payments of $22.4 million that are spread relatively evenly in 2022 through 2030. 

In addition, we had $19.6 million of unrecognized tax benefits (including discontinued operations) recorded as liabilities 
related to uncertain tax positions at December 31, 2021, which we are uncertain as to if or when such amounts may be 
settled. We had a liability of $2.2 million recorded for potential penalties and interest (including discontinued operations) 
related to these unrecognized tax benefits. 

Sources of Cash 

Revolving Credit Facility 

During the years ended December 31, 2021 and 2020, our Credit Facility had an average daily balance of $295.3 million 
and $704.5 million, respectively. The weighted average annual interest rate on the outstanding balance under the Credit 
Facility, excluding the effect of interest rate swaps, was 2.6% and 2.7% at December 31, 2021 and 2020, respectively. As 
of December 31, 2021, there were $8.9 million letters of credit outstanding under the Credit Facility and the applicable 
margin on borrowings outstanding was 2.4%. We executed two amendments to our facility during the three-year period 
ended December 31, 2021; see Note 14 (“Long-Term Debt”) to our Financial Statements for details of these amendments. 

Certain Facility Terms. Our Credit Facility matures in November 2024 and has an aggregate revolving commitment of 
$750.0 million. Portions of the Credit Facility up to $50.0 million are available for the issuance of swing line loans and 
$50.0 million is available  for the issuance of letters  of credit.  Subject to certain conditions,  including  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. 

Covenants. Our Credit Facility agreement requires that we meet certain financial ratios (see Note 14 (“Long-Term Debt”) 
to  our  Financial  Statements)  and  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 a 
result  of  the  financial  ratio  requirements,  $502.5  million  of  the  $506.6  million  of  undrawn  capacity  was  available  for 
additional borrowings as of December 31, 2021. We were in compliance with all other covenants under our Credit Facility 
agreement. 

Senior Notes 

As  of  both  December  31,  2021  and  2020,  we  had  a  principal  balance  of  $1.3  billion  of  outstanding  senior  notes  that 
consisted of the following: 

•  $800.0 million of 6.25% senior notes due in April 2028 and 
•  $500.0 million of 6.875% senior notes due in April 2027. 

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

price of up to $50.0 million. The agreement terminates upon the earlier of (i) the sale of all shares of common stock subject 
to the agreement or (ii) the termination of the agreement by us or by each of the sales agents. Any sales agent may also 
terminate the agreement but only with respect to itself. We use the net proceeds of these offerings for general corporate 
purposes. During the year ended December 31, 2021, we sold 357,148 shares of common stock for net proceeds of $3.4 
million pursuant to the ATM Agreement. See Note 16 (“Equity”) to our Financial Statements for further details of this 
agreement. 

Other Sources of Cash 

Business Dispositions and Other Asset Sales. We received proceeds of $112.9 million and $52.6 million from business 
dispositions and other asset sales during the years ended December 31, 2021 and 2020, respectively. We typically use the 
proceeds from these sales to repay borrowings outstanding under our Credit Facility, however, we are not able to estimate 
the timing of asset sales nor the amount of proceeds to be received and as such, we do not rely on asset sale proceeds as a 
future source of capital. 

Cash Flows 

Our cash flows, as reflected in our consolidated statements of cash flows, are summarized below: 

(in thousands) 
Net cash provided by (used in):

Operating Activities. The decrease in net cash provided by operating activities was primarily due to reduced cash inflows 
from revenue, deferred revenue, accounts receivable, contract costs and the receipt of cash proceeds from sales and use 
tax audit settlements in 2020 with no comparable settlements in 2021, as well as increased cash outflow for inventory. 
Partially offsetting these decreases in operating cash were decreased cash outflows for cost of sales, accounts payable and 
other liabilities, SG&A expenses and restructuring charges, and the receipt of additional cash proceeds from the July 2020 
Disposition in 2021. 

Investing Activities. The change from net cash used in to net cash provided by investing activities was primarily due to a 
$60.3 million increase in proceeds from business dispositions and other sales of property, plant and equipment and a $42.4 
million decrease in capital expenditures. 

Financing Activities. Net cash used in  financing activities  was relatively unchanged primarily due to several offsetting 
items, including an increase of $3.1 million in net repayments of long-term debt, which was offset by $3.4 million of net 
proceeds  from  the  issuance  of  common  stock  under  our  ATM  Agreement  during  2021 and  a  $2.8  million  decrease  in 
payments for debt issuance costs.

Critical Accounting Estimates 

We describe our significant accounting policies more fully in Note 2 (“Basis of Presentation and Significant Accounting 
Policies”) to our Financial Statements. As disclosed in Note 2, the preparation of financial statements in conformity with 
GAAP 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. 

Depreciation 

Property, plant and equipment, net at December 31, 2021 was $2.2 billion and depreciation expense was $167.6 million 
for the year ended December 31, 2021.  Property, plant and equipment are carried at cost and depreciated using the straight-
line basis over the estimated useful life of the asset. 

Our  estimate  of  useful  lives  and  salvage  values  are  based  on  assumptions  and  judgments  that  reflect  both  historical 
experience and expectations regarding future use of our assets, including wear and tear, obsolescence, technical standards, 
market demand and geographic location. 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  and  results  of 
operations. 

The estimated useful life of an asset is monitored to determine its appropriateness, especially when business circumstances 
change. For example, changes in technology, excessive wear and tear, or unanticipated government actions may result in 
a shorter estimated useful life than originally anticipated. In these cases, we would depreciate the remaining net book value 
over the new estimated remaining life, thereby increasing depreciation expense per year on a prospective basis. Likewise, 
if the estimated useful life is increased, the adjustment to the useful life would decrease depreciation expense per year on 
a prospective basis. 

Impairment of Assets 

During the year ended December 31, 2021, we recorded long-lived and other asset impairment of $21.4 million. 

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. 

Compression Fleet. The fair value of a compressor 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. See Note 18 (“Long-Lived and Other Asset Impairment”) and Note 23 (“Fair Value 
Measurements”) to our Financial Statements for further details of our fleet asset impairments. 

48 

Impairment Assessment of Goodwill 

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. The fair value calculation required 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. See Note 2 (“Basis of Presentation and Significant 
Accounting Policies”) and Note 9 (“Goodwill”) for further details of the assessment performed on our goodwill in 2020. 

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. 

Recent Accounting Developments 

See Note 3 (“Recent Accounting Developments”) to our Financial Statements. 

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, however, our interest rate swaps mature 
in the first quarter of 2022, at which time all borrowings under the Credit Facility will be subject to variable interest rates. 

After taking into consideration our interest rate swaps, we did not have any debt subject to variable interest rates as of 
December 31, 2021. Not considering our interest rate swaps, a 1% increase in the effective interest rate on the outstanding 
balance under our Credit Facility at December 31, 2021 would have resulted in an annual increase in our interest expense 
of $2.3 million.

Item 9A. Controls and Procedures 

Management’s Evaluation of Disclosure Controls and Procedures 

As of the end of the period covered by this 2021 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, 2021, 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, 2021. 

The effectiveness of internal control over financial reporting as of December 31, 2021 was audited by Deloitte & Touche 
LLP, an independent registered public accounting firm, as stated in its report found within this 2021 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,  2021,  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,  2021,  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 as of and for the year ended December 31, 2021, of the Company 
and our report dated February 23, 2022, expressed an unqualified opinion on those financial statements. 

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, 2021 and 2020, the related consolidated statements of operations, comprehensive income, equity, and cash 
flows, for each of the three years in the period ended December 31, 2021, and the related notes 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, 2021 and 2020, and the results of its operations 
and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31, 2021,  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,  2021, 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 23, 2022 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 relates. 

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, 2021, the Company retired 230 units from the active fleet resulting in an 

F-1 

asset  impairment  charge  of  $21.2 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, including the need to involve our fair value specialists, 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: 

•   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. 

•   We tested the completeness and accuracy of the  compressor  units identified for retirement  by performing the 

following procedures: 

–   Comparing  the  final  listing  of  retired  compressor  units  to  the  list  evaluated  and  approved  by 

management. 

–   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. 

•   We  evaluated  the  reasonableness  of  Fair  Market  Value  assigned  by  management  on  impaired  units  by  using 

Internal Fair Value Specialists. 

•   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: 

–   Comparing  the  rationale  for  compression  units  identified  with  historical  rationales  made  for 

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

–   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. 

–   Comparing  the  compression  units  identified  to  internal  communications  to  management  and  the 

Board of Directors.  

–   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. 

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 

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 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 is 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 

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 both December 31, 2021 and 2020, Chevron U.S.A. Inc. and Williams Partners accounted for 14% and 10% of our 
trade accounts receivable balance, respectively. The following table summarizes the activity in our allowance for credit

Inventory 

Inventory consists of parts used for maintenance of natural gas compression equipment. Inventory is stated at the lower of 
cost and net realizable value using the average cost method.

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 

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 follows the Accounting Standards Codification 
Topic 606 Revenue from Contracts with Customers guidance. 

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 

 
 
 
 
 
 
 
 
 
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 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. 

F-13 

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 

Reference Rate Reform 

In June 2021, we prospectively adopted 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. On June 10, 2021, we amended one of our interest rate 
swap agreements and determined that the modifications meet the criteria for the optional expedients and exceptions, which 
allow us to forego dedesignation of the hedging relationship and to subsequently assess effectiveness on a qualitative basis. 
The adoption of ASU 2020-04 did not have a material impact on our consolidated financial statements. In the first quarter, 
we evaluated Amendment No. 3 to our Credit Facility and determined that  ASU 2020-04  was not applicable. We will 
continue to assess any modifications to our interest rate swap and Credit Facility agreements during the effective period 
of this update and will apply the amendments as applicable. 

 4. Business Transactions 

July 2021 Dispositions 

In  July  2021,  we  completed  sales  of  certain  contract  operations  customer  service  agreements  and  approximately  575 
compressors,  comprising  approximately  100,000  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. We received 
cash consideration of $60.3 million for the sales and recorded gains on the sales of $13.0 million in gain on sale of assets, 
net in our consolidated statements of operations during the year ended December 31, 2021. 

F-14 

February 2021 Disposition 

In February 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. We recorded 
a gain on the sale of $6.0 million in gain on sale of assets, net in our consolidated statements of operations during the year 
ended December 31, 2021. 

July 2020 Disposition 

In July 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 was 
received on the first anniversary of the closing date in July 2021, and $3.5 million was received through the purchase of 
turbocharger goods and services under the supply agreement, including $2.8  million that was received during the year 
ended December 31, 2021. We recognized a gain on the sale of $9.3 million in gain on sale of assets, net in our consolidated 
statements of operations during the year ended December 31, 2020. 

March 2020 Disposition 

In March 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 

In August 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 under the Credit Facility. 

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  was  recorded  as  goodwill.  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 were 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. 

F-15 

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. 

Unaudited Pro Forma Financial Information 

Unaudited pro forma financial information for the year ended December 31, 2019 was derived by adjusting our historical 
financial  statements  in  order  to  give  effect  to  the  assets  and  liabilities  acquired  in  the  Elite  Acquisition.  The  Elite 
Acquisition  is  presented  in  this  unaudited  pro  forma  financial  information  as  though  the  acquisition  occurred  as  of 
January 1, 2018, and reflects the following: 

•  the acquisition of substantially all of Elite Compression’s assets, including a compression fleet of approximately 

430,000 horsepower, vehicles, real property and inventory, and certain liabilities; 

•  borrowings of $214.0 million under the Credit Facility for cash consideration exchanged in the acquisition; and 
•  the  exclusion  of  $7.8  million  of  financial  advisory,  legal  and  other  professional  fees  incurred  related  to  the 
acquisition and recorded to transaction-related costs in our consolidated statements of operations during the year 
ended December 31, 2019. 

The unaudited pro forma financial information below is presented for informational purposes only and is not necessarily 
indicative of our results of operations that would have occurred had the transaction been consummated at the beginning of 
the period presented, nor is it necessarily indicative of future results.

The results of operations attributable to the assets and liabilities acquired in the Elite Acquisition have been included in 
our consolidated financial statements as part of our contract operations segment since the date of acquisition. Revenue 
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 

In  August 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 

We completed the Spin-off in 2015. 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, including a tax matters agreement, which 
governs the respective rights, responsibilities and obligations of Exterran Corporation and us with respect to certain tax 
matters. As of both December 31, 2021 and 2020, we had $7.9 million 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 
related to these unrecognized tax benefits recorded to noncurrent assets associated with discontinued operations as of both 
December 31, 2021 and 2020.

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 nine years and most include options to extend the lease term, at our 
discretion, for an additional six months to ten 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.

We  recognized  goodwill  in  connection  with  the  Elite  Acquisition,  which  represented  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. Beginning in the first quarter of 2020, the COVID-19 pandemic caused a significant deterioration 
in  global  macroeconomic  conditions,  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 goodwill impairment loss of $99.8 million during the first quarter 
of 2020. 

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 determined 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  was estimated using our  most recent forecast and the  weighted average cost of capital. The 
market  approach  used  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 were our cash flow forecasts, our estimate of the market’s weighted average cost of capital and 
market multiples.  

10. Intangible Assets, net 

Intangible  assets  include  customer  relationships  and  contracts  associated  with  various  business  and  asset  acquisitions. 
These acquired intangible assets were recorded at fair value determined as of the acquisition date and are being amortized 
over the period we expect to benefit from the assets. Intangible assets, net consisted of the following:

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 $2.6 million and $3.2 million associated with sales commissions 
recorded in our consolidated balance sheets at December 31, 2021 and 2020, 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 $22.8 million and $26.0 million associated with freight and 
mobilization recorded in our consolidated balance sheets at December 31, 2021 and 2020, 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, 2021, 2020 
and 2019, we amortized $2.2 million, $3.0 million and $2.6 million, respectively, related to sales commissions and $17.8 
million, $23.6 million and $20.7 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 has, among other things, 
replaced  our  existing  ERP,  supply  chain  and  inventory  management  systems  and  expanded  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, 2021 and 2020, we had $12.7 million and $7.7 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 $0.7 million and $0.3 million at December 31, 2021 and 2020, respectively. We 
recorded $0.3 million of amortization expense to SG&A in our consolidated statements of operations during each of the 
years ended December 31, 2021 and 2020.

As of December 31, 2021, there were $8.9 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  2.6%  and  2.7%  at  December 31, 2021  and  2020, 
respectively. As a result of the facility’s ratio requirements (see below), $502.5 million of the $506.6 million of undrawn 
capacity  was  available  for  additional  borrowings  as  of  December 31, 2021.  We  were  in  compliance  with  all  other 
covenants under our Credit Facility agreement. 

Amendments to the Credit Facility 

Amendment No. 3 

In February 2021, we amended our Credit Facility to, among other things, reduce the aggregate revolving commitment 
from $1.25 billion to $750.0 million and adjust the maximum Senior Secured Debt to EBITDA and Total Debt to EBITDA 
ratios, as defined in the Credit Facility agreement, to those listed in the table below.

We incurred $1.8 million in transaction costs related to Amendment No. 3, which  were included in other assets in our 
consolidated balance sheets and are being amortized over the remaining term of the Credit Facility. In addition, we wrote 
off $4.9 million of unamortized deferred financing costs as a result of the amendment,  which  was recorded to interest 
expense in our consolidated statements of operations during the year ended December 31, 2021. 

Amendment No. 2 

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 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 sheets and are being amortized over the remaining term of the Credit Facility. 

Other Facility Terms 

Subject to certain conditions, including 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 and $50.0 million is available for the issuance of letters of credit. 

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,  $2.0  million  and  $1.9  million  in  commitment  fees  during  the  years  ended 
December 31, 2021, 2020 and 2019, 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, 2021, 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 

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

2028 Notes and 2027 Notes 

In December 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%. The $500.0 million of notes were issued at 100% of their face value and 
have an effective interest rate of 6.8%. 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 $500.0 million 
of notes were issued at 100% of their face value and have an effective interest rate of 7.9%. 

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 Archrock Partners 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 

In April 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.

16. Equity 

At-the-Market Continuous Equity Offering Program 

In February 2021, we entered into the ATM Agreement, pursuant to which we may offer and sell shares of our common 
stock from time to time for an aggregate offering price of up to $50.0 million. We use the net proceeds of these offerings, 
after deducting sales agent fees and offering expenses, for general corporate purposes. Offerings of common stock pursuant 
to the ATM Agreement will terminate upon the earlier of (i) the sale of all shares of common stock subject to the ATM 
Agreement or (ii) the termination of the ATM Agreement by us or by each of the sales agents. Any sales agent may also 
terminate the ATM Agreement but only with respect to itself. 

During the year ended December 31, 2021, we sold 357,148 shares of common stock for net proceeds of $3.4 million 
pursuant to the ATM Agreement. 

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.

Contract Assets and Liabilities 

Contract Assets 

As of December 31, 2021 and 2020, our receivables from contracts  with customers, net  of allowance  for credit losses, 
were $84.7 million and $95.6 million, respectively. 

Contract Liabilities 

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. Our contract liabilities were $4.4 
million and $4.6 million as of December 31, 2021 and 2020, respectively, and were included in deferred revenue and other 
liabilities in our consolidated balance sheets. During the year ended December 31, 2021, we deferred revenue of $10.2 
million and recognized $10.4 million as revenue. The revenue recognized and deferred during the period 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 of 2020. 

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:

12 (“Hosting Arrangements”) for further details. 

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 of $1.7 million related to 
these activities during the first quarter of 2020. No additional costs will be incurred for this organizational restructuring. 

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 incurred severance costs of $7.0 million to right-size our business. No additional costs will be 
incurred under this restructuring plan.

During the third quarter of 2020, a plan to dispose of certain non-core properties was approved by management. We have 
incurred  $1.5  million  of  costs  as  a  result  of  these  property  disposals.  No  additional  costs  will  be  incurred  under  this 
restructuring plan. 

During the third quarter of 2021, management approved and initiated a plan to exit a facility no longer deemed economical 
for our business, and in the fourth quarter, we incurred $0.9 million of costs to complete the exit of this facility. We do not 
expect to incur additional material costs under this restructuring plan. 

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

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. 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 a 
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.

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 was 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,  2021,  we  had  U.S. federal  and  state  NOL  carryforwards  of  $868.5  million  and  $317.1  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 2022, respectively, though $629.5 million of the 
U.S. federal and $167.7 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 $0.7 million and $1.0 million as of December 31, 2021 and 2020, 
respectively. 

At  December 31,  2021,  we  had  U.S.  federal  and  state  tax  credit  carryforwards  of  $3.0  million  and  $0.1  million, 
respectively. If not used, the federal and state tax credit carryforwards will begin to expire in 2037 and 2041, respectively.

We had $19.6 million, $18.9 million and $18.5 million of unrecognized tax benefits at December 31, 2021, 2020 and 2019, 
respectively,  of  which  $2.1  million,  $2.9  million  and  $3.2  million,  respectively,  would  affect  the  effective  tax  rate  if 
recognized and $7.9 million, $7.9 million and $8.3 million, respectively, would be reflected in income from discontinued 
operations, net of tax if recognized. 

We recorded $2.2 million, $2.1 million and $2.1 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, 2021, 2020 and 2019, 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. 
We recorded $0.1 million of potential interest expense and penalties in our consolidated statements of operations during 
the year ended December 31, 2021, and releases of $0.1 million during each of the years ended December 31, 2020 and

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 not currently involved in any state audits. 
During the year ended December 31, 2019, we settled certain state audits, which resulted in a refund of $2.4 million and 
a reduction in previously-accrued uncertain tax benefits of $4.4 million. 

As of December 31, 2021, we believe it is reasonably possible that $2.6 million of our unrecognized tax benefits, including 
penalties, interest and discontinued operations, will be reduced prior to December 31, 2022 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 

In March 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 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  is  determined  by  dividing  net  income  (loss),  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 participating securities do not have a contractual obligation to participate in our undistributed 
losses. 

Diluted  net  income  (loss)  per  common  share  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.

We use derivative instruments to manage our exposure to fluctuations in the variable interest rate of our Credit Facility. 
As of December 31, 2021, we had $300.0 million notional value of interest rate swaps outstanding, which expire in March 
2022. We entered into these swaps to offset changes in expected cash flows due to fluctuations in the associated variable 
interest  rates  and  designated  them  as  cash  flow  hedges.  The  counterparties  to  these  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 an adverse effect on us. We have no collateral posted for our 
derivative instruments.

During the year ended December 31, 2021, we dedesignated $125.0 million notional value of our interest rate swaps. The 
fair  value  of  this  interest  rate  swap  immediately  prior  to  dedesignation  was  a  liability  of  $1.6  million.  The  associated 
amount in accumulated other comprehensive loss related to this interest rate swap is being amortized into interest expense 
over the remaining term of the swap through March 2022. Changes in the fair value of the dedesignated interest rate swap 
subsequent to dedesignation are recorded in interest expense. 

The remaining $175.0 million notional value of our interest rate swaps continue to be designated as cash flow hedging 
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 $1.2  million of  the deferred pre-tax loss attributable to interest rate swaps included in accumulated other 
comprehensive  loss  at  December 31,  2021  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, 2021, the weighted average effective fixed interest rate of our interest rate swaps was 1.8%.

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: 

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

of measurement. 

•  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. 

•  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 position measured at fair value on a recurring basis, with pricing 
levels as of the date of valuation:

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.

Compressors 

During the years ended December 31, 2021 and 2020, we recorded nonrecurring fair value measurements related to our 
idle  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, 2021  and  2020  was  as 
follows:

The significant unobservable inputs used to develop the above fair value measurements were weighted by the relative fair

inputs 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 fair value of our fixed rate debt is estimated using yields observable in active markets, which are Level 2 inputs, and

Stock Incentive Plans 

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, 2021, 2020 and 2019, we 
withheld 283,972 shares valued at $2.5 million, 236,752 shares valued at $1.8 million and 212,080 shares valued at $2.0 
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. 

Restricted Stock 

Our  outstanding  restricted  stock  generally  consists  of  stock-settled  restricted  stock  awards  and  performance-based 
restricted stock units, and cash-settled performance-based restricted stock units. 

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

Some  of  our  performance-based  restricted  stock  units  have  a  market-based  condition  that  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 the 
date  specified  in  the  award  agreement  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 following table presents the inputs used and the grant date fair value calculated in the Monte Carlo simulation model 
for the performance-based restricted stock units awarded during the years ended December 31, 2021, 2020 and 2019:

and units to be recognized over the weighted-average period of 1.8 years. Cash paid upon vesting of cash-settled restricted 
stock units during the years ended December 31, 2021, 2020 and 2019 was $0.6 million, $0.5 million and $1.3 million,

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, 2021, 521,719 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 or 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.  There  are  100,000 shares  reserved  under  the  DSDP  and,  as of  December 31, 2021,  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  IRS  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 $4.4 million, $5.6 million and $6.8 million during the years ended December 31, 2021, 2020 and 2019, 
respectively. 

26. Commitments and Contingencies 

Insurance 

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.

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, 2021  and  2020,  we  accrued  $5.8  million  and  $5.6  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. 

In 2021, one of our sales and use tax audits advanced from the audit review phase to the contested hearing phase. We 
accrued $0.6 million and $0.9 million for this audit as of December 31, 2021 and 2020, respectively. 

In 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 related to this settlement and have a $2.0 million accrued liability recorded as of December 31, 
2021, which is included in our accrual for non-income-based tax audits discussed above. 

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, we  had an 
indemnification liability (including penalties and interest), in addition to the tax contingency above, of $1.6 million for 
our share of non-income-based tax contingencies related to audits being managed by Exterran Corporation. During the 
year ended December 31, 2021, these audits were settled and our indemnification liability was reduced to zero. 

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.  As  of 
December 31, 2021, JDH Capital owned 11.1% of our outstanding common stock. 

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 compensation in his role as Director and Mr. Rebrook received 
no compensation in his role as Director in 2020. In December 2020, the Board of Directors voted to approve the payment 
of Director cash and equity compensation to Mr. Rebrook beginning in 2021. 

F-40 

Revenue  from  Hilcorp  and  affiliates  was  $38.2  million,  $40.3  million  and  $31.4  million  during  the  years  ended 
December 31, 2021,  2020  and  2019,  respectively.  Accounts  receivable,  net  due  from  Hilcorp  and  affiliates  was  $3.7 
million and $3.9 million as of December 31, 2021 and 2020, 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, 2021, 2020 and 2019.

Hurricane Ida made landfall in Louisiana on August 29, 2021, causing operational disruptions, damage to compressors 
and a temporary shutdown of facilities in Louisiana that negatively impacted our financial performance in the quarter. In 
the third quarter of 2021, we recorded $2.0 million in depreciation expense associated with the damaged assets, and in the 
fourth quarter, we recognized an insurance recovery of $2.8 million related to the facility and compressor damages in other 
income, net in our consolidated statements of operations, after a deductible of $0.9 million. A corresponding receivable 
for $2.8 million was recorded to our consolidated balance sheet as of December 31, 2021. The remaining portion of our 
insurance claim pertaining to business interruption is in process. We are currently unable to estimate the expected amount 
to be recovered, however, any amount recovered will not be subject to an additional deductible.
