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 Exterran Holdings, Inc., the parent entity of Universal Compression Holdings, Inc. and Hanover Compressor Company. 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 primary focus on midstream natural gas compression and a commitment to helping our customers produce, compress and transport natural gas in a safe and environmentally responsible way. We are the leading provider of natural gas compression services to customers in the energy industry throughout the U.S., in terms of total compression fleet horsepower, and a leading supplier of aftermarket services to customers that own compression equipment in the U.S. Our business supports a must–run service that is essential to the production, processing, transportation and storage of natural gas. Our mission to help our customers deliver natural gas, an affordable and cleaner energy source, to a variety of critical industries, to generate electricity and to directly heat and power our homes, is more critical than ever.

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 79% of our operating fleet being used in the gathering and processing cycle stages. The remaining 21% 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.

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 oil and natural gas 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, 2022, 2021 and 2020, we generated 80%, 83% and 84%, respectively, of our total revenue from contract operations.

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, 2022, the average age of our operating fleet was 11 years.

The following table summarizes the size of our natural gas compression fleet as of December 31, 2022:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ |  | Aggregate |  | ​ |

Total |  | 3,493 |  | 3,726 |  | 100 | %

​

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 the amount of horsepower associated with a specific application, and are required to pay a reduced monthly fee during periods of limited or disrupted natural gas 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.

Table Archrock, Contents

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 business. During the years ended December 31, 2022, 2021 and 2020, we generated 20%, 17% and 16%, 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, 2022, 84% 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 are 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, 2022, our availability was 99.1%. 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 2022 total recordable incident rate of 0.32.

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

9

Table Archrock, Contents

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 four 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 compressor fleets. This project, among other things, has helped us achieve increased asset uptime, improved the efficiency of our field service technicians, improved our supply chain and inventory management and reduced 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 oil and natural gas 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.

Improve profitability. We are focused on increasing productivity and optimizing our processes. Between 2019 and 2021, we invested in 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. During 2022, our focus shifted to the integration of our process and technology transformation project into our operations, which we expect will lower our internal costs and improve our profitability over time. Implementing telematics and advanced data analysis across our fleet has enabled 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

10

Table Archrock, Contents

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 approximately 341,000 and 147,000 non–core horsepower during the years ended December 31, 2022 and 2021, respectively, which drove an increase in our large operating horsepower from 77% of our fleet as of December 31, 2020, to 84% as of December 31, 2022.

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 oil and natural gas 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 four 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.

Sales and Marketing

Our marketing and client service functions are coordinated and performed by our sales and field service personnel. Salespeople, application engineers and field service personnel qualify, analyze and scope new compression applications as well as 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.

11

Table Archrock, Contents

Customers

Our customer base consists primarily of companies engaged in all aspects of the oil and gas natural industry, including large integrated and independent oil and natural gas, 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, 2022, 2021 and 2020, our five most significant customers collectively accounted for 32%, 31% and 28%, 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, 2022, 2021 and 2020.

We have pricing agreements in place with all of our primary suppliers of compression equipment, parts and services, including Ariel Corporation, Waukesha Pearce Industries and Caterpillar, Inc. 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.

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.

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, with both a supplemental rule proposal by the EPA and a separate BoLM rule proposal addressing methane emissions on public lands issued in November 2022. Among the newly proposed methane requirements that may impact our operations broader applicability to compression equipment relative to the existing rules, increased work practices and inspection requirements and mandates for certain new zero–emissions equipment.

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. In June 2021, the EPA announced it will reconsider the December 2020 decision, with a decision expected in 2023. In a draft assessment in April 2022, the Clean Air Scientific Advisory Committee favored maintaining the 2015 NAAQS ozone standard. Those decisions have been subject to judicial challenge. 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 involving new NAAQS standards.

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 or in the future might otherwise have an opportunity to 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 action by Congress also occurred in August 2022 with the Inflation Reduction Act, which provides $391 billion in funding for research and development and incentives for low–carbon energy production methods, carbon capture, and other programs directed at encouraging de–carbonization and 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 of $190 per ton, as suggested by the EPA, expected to be announced by the Interagency Working Group in April 2023. That figure is intended to be used to guide federal decisions on the costs and benefits of various policies and approvals; such efforts have been the subject of a series of judicial challenges, which have been largely unsuccessful to date. 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 the proposed methane rules discussed above, 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 October 2022, the U.S. Supreme Court heard arguments in a case on the appropriate scope of CWA jurisdiction; the outcome of that case may shape the administration’s approach to its ongoing jurisdictional rulemaking effort. In the meantime, in October 2022, the EPA and the Army Corps of Engineers announced a final rule intended to provide a legally durable definition of “waters of the United States” designed to clarify and stabilize the scope of the agencies’ jurisdictions. The final rule, which was published in the Federal Register in January 2023 and becomes effective on March 20, 2023, restores certain water protections that were in place prior to 2015 under the CWA for traditional navigable water, the territorial areas, interstate waters and upstream water resources that significantly affect those waters.

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.

The COVID–19 pandemic has largely run its course in the U.S. While we do have comprehensive pandemic–focused procedures in place, we relaxed many of the COVID–19–specific requirements in late 2022 in light of, among other things, our COVID–19 case trends and similar relaxation of restrictions and controls by local and federal government authorities, in reliance on the latest recommendations and assessments of relevant medical experts. If conditions change, such as we see an increase in the number of new COVID–19 cases or governmental and/or medical advice changes, we will carefully consider reimplementing appropriate procedures geared toward ensuring the health, safety and well–being of our employees, customer and vendors. At this time, we do not know if or how any additional developments with the pandemic, if any, or any regulatory initiatives adopted in response to any such developments, 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, 2022, we employed approximately 1,100 employees in 15 states and conducted business in 41 states. None of our employees are subject to a collective bargaining agreement.

Table Archrock, Contents

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 our seven independent directors are female or identify as a member of an underrepresented racial/ethnic group. Similarly, one–third of our executive leadership team is female and 29% of our total workforce is ethnically diverse.

We support gender and ethnic pay equity and believe we offer competitive and comprehensive compensation benefits packages that include bonuses, 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 (including 16 hours per year as paid time to volunteer), 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 Governance and Sustainability 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.

Learning and 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 40,500 hours of operational and technical training during 2022. 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.

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 16 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 achieved excellent safety performance, with a total recordable incident rate of 0.32 in 2022. While no incidents are acceptable, the incidents we experienced were extremely minor in nature and resulted in no lost time. 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.

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 16 hours per year of 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 2022 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

Pandemics and other public health crises, including the ongoing 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.

Pandemics, such as the COVID–19 pandemic, or other public health crises could significantly 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.

18

Table Archrock, Contents

The extent to which our operating and financial results continue to be affected by the COVID–19 pandemic and may be affected by future pandemics or other public health crises will depend on various factors and consequences beyond our control, such as the duration and scope of such pandemic or public health crisis, additional actions by businesses and governments in response to the pandemic and the speed and effectiveness of responses to combat any such pandemic or public health crisis. Any future pandemic or public health crisis 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.

An increase in inflation could have adverse effects on our results of operation.

Inflation continues to rise and has caused the Federal Reserve to raise interest rates with indications of future increases, which has created further uncertainty for the economy and for our customers. If inflationary pressures continue into 2023, this will increase our labor costs and the costs of parts, lube oil and other materials used in our operations. Continued inflation or an increase in inflation rates could negatively affect our profitability and cash flows, due to higher wages, higher operating costs, higher financing costs, and/or higher supplier prices. We may be unable to pass along such higher costs to our customers. In addition, inflation may adversely affect customers’ financing costs, cash flows, and profitability, which could adversely impact their operations and our ability to collect receivables.

The conflict in Ukraine and related price volatility and geopolitical instability could negatively impact our business.

In late February 2022, Russia launched significant military action against Ukraine. The conflict has caused, and could intensify, volatility in natural gas prices, and the extent and duration of the military action, sanctions and resulting market disruptions could be significant and could potentially have a substantial negative impact on the global economy and/or our business for an unknown period of time. Any such volatility and disruptions may also magnify the impact of other risks described in this “Risk Factors” section.

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.

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.

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.

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.

Old Ocean Reserves, an affiliate of our customer Hilcorp, has the right to designate one director to serve on our Board of Directors as long as Old Ocean Reserves or it successors (together with its affiliates) owns at least 7.5% of our outstanding common stock. As of December 31, 2022, Old Ocean Reserves owned 10.8% of our outstanding common stock. Given its ownership level and board representation, Old Ocean Reserves 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, 2022, 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, 2022. 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 of 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;

| • | 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.

As of December 31, 2022, we had $1.5 billion in outstanding debt obligations, net of unamortized debt premiums and unamortized deferred financing costs, outstanding under our Credit Facility and Senior Notes. 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 level and associated commitments could have important 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 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, 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.

Our Credit Facility is also subject to financial covenants, including the following ratios, as defined in the corresponding agreement:

​ | ​ | ​
EBITDA to Interest Expense |  | 2.5 to 1.0
Senior Secured Debt to EBITDA |  | 3.0 to 1.0
Total Debt to EBITDA |  |
January 1, 2023 through September 30, 2023 |  | 5.50 to 1.0
Thereafter (1) |  | 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 dividends. 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, 2022, we were in compliance with all covenants under the Debt Agreements.

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

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

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

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

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

Borrowings under our Credit Facility are 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.

Our Credit Facility contains LIBOR benchmark replacement provisions. However, at this time, there can be no assurance as to whether any alternative benchmark or resulting interest rates may be more or less favorable than LIBOR or any other unforeseen impacts of the discontinuation of LIBOR. As a result, the proposals or consequences related to this transition could have a material adverse effect on our debt service obligations, financing costs, liquidity, financial condition, results of operations or cash flows and could impair our access to the financial markets.

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.

Borrowings under our Credit Facility bear interest at a rate per annum of either, at our election, the U.S. dollar LIBOR rate for specified interest periods or a base rate, plus an applicable margin. The publication of U.S. dollar LIBOR rates for the most common tenors (overnight and one, three, six and twelve months) will cease publication on June 30, 2023. Our Credit Facility requires that we execute an amendment that establishes an alternate reference rate should the U.S. dollar LIBOR cease to be published (among other circumstances), to be agreed upon by us and the administrative agent under our Credit Facility and giving due consideration to the then-prevailing market convention for determining a rate of interest for syndicated loans in the U.S. at such time, with notice rights subject to objection by required lenders under the Credit Facility. Until an alternate reference rate is established, borrowings under our Credit Facility will be limited to base rate borrowings, which may bear a higher interest rate than LIBOR and, in turn, potentially increase our interest expense. Uncertainty regarding the continued use and reliability of LIBOR as a benchmark rate and uncertainty regarding its replacement could disrupt the financial markets or adversely affect arrangements tied to LIBOR.

The Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee (“ARRC”), which identified the Secured Overnight Financing Rate (“SOFR”) as its preferred alternative to U.S. dollar LIBOR in financial contracts. There can be no assurance that SOFR or any other alternative reference rate will perform in the same way as LIBOR would have at any time, including as a result of changes in interest and yield rates in the market, market volatility or global or regional economic, financial, political, regulatory, judicial or other events. Additionally, ARRC has recommended credit spread adjustments for use with SOFR due to LIBOR representing an unsecured lending rate while SOFR represents a secured lending rate. However, market acceptance of the ARRC–recommended credit spread adjustments, as opposed to no or alternative credit spread adjustments, has been mixed. Accordingly, we cannot predict whether changes related to the phase–out of LIBOR, including any credit spread adjustments, insufficient liquidity in the SOFR or alternative reference rate markets or other reforms, as they occur, will have an adverse effect on 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.

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 32%, 31% and 28% of our revenues during the years ended December 31, 2022, 2021 and 2020, 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. Moreover, we have limited ability to increase prices during our initial contract terms. As a result, we are unable to pass increases in the prices of the equipment, materials and services we utilize to provide contract operations services, as a result of inflation of otherwise, onto our customers, which could result in a reduction in net income. 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 (as a result of inflation or otherwise), 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.

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 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 inflation, ongoing effect of the COBID–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

25

Table Archrock, Contents

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.

Our ability to use NOLs and interest expense limitation carryovers to offset future income may be limited.

Our ability to use any NOLs and interest expense limitation carryovers 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. During the year ended December 31, 2019, the IRS 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 (and certain other losses and/or credits) may be limited. Such a limitation could, for any given year, have the effect of increasing the amount of our U.S. federal and state income tax liability, which would negatively impact the amount of after–tax cash available for distribution to our stockholders and our financial condition.

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

26

compete effectively or obtain adequate insurance in the future. See Part I, Item 3 “Legal Proceedings” and Note 15 to our Financial Statements for additional information regarding certain legal proceedings to which we are a party.

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, with both a supplemental rule proposal by the EPA and a separate BoLM rule proposal addressing methane emissions on public lands issued in November 2022. Among the newly proposed methane requirements that may impact our operations are broader applicability to compression equipment relative to the existing rules, increased work practices and inspection requirements and mandates to certain new zero–emission equipment.

Meanwhile, several states — including, most notably, New Mexico and Colorado — have been developing their own more stringent methane emissions rules that will or are anticipated to impose additional requirements on the industry and that may impose stricter requirements than any 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.

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. In June 2021, the EPA announced it will reconsider the December 2020 decision, with a decision expected in 2023. In a draft assessment in April 2022, the Clean Air Scientific Advisory Committee favored maintaining the 2015 NAAQS ozone standard. Those decisions have been subject to judicial challenge and remain subject to reconsideration by the EPA. 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 involving 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 or in the future might otherwise have an opportunity to provide contract 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.

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. Any failure to obtain or delay in obtaining required permits, licenses and other governmental approvals by our customers could result in production delays and thereby, indirectly materially and adversely impact our operations and business.

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 oil, natural gas 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, and such requirements may vary.

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

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

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

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

Additionally, in March 2022, the SEC proposed new rules relating to the disclosure of a range of climate–related data risks and opportunities, including financial impacts, physical and transition risks, related governance and strategy and GHG emissions, for certain public companies. We are currently assessing this rule but at this time we cannot predict the ultimate impact of the rule on our business or those of our customers. The SEC originally planned to issue a final rule by October 2022, but most commentators now expect a final rule to be issued in early 2023. To the extent this rule is finalized as proposed, we or our customers could incur increased costs related to the assessment and disclosure of climate-related risks and certain emissions metrics. In addition, enhanced climate disclosure requirements could accelerate the trend of certain stakeholders and lenders restricting or seeking more stringent conditions with respect to their investments in certain carbon intensive sectors.

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 GHG emissions 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 our sales volumes, revenues and margins.

A climate–related decrease in demand for oil and natural gas could negatively affect our business.

Supply and demand for oil and natural gas is dependent upon a variety of factors, many of which are beyond our control. These factors include, among others, the potential adoption of new government regulations, including those related to fuel conservation measures and climate change regulations, technological advances in fuel economy and energy generation devices. For example, legislative, regulatory or executive actions intended to reduce emissions of GHGs could increase the cost of consuming crude oil and natural gas, thereby potentially causing a reduction in the demand for such products. A broader transition to alternative fuels or energy sources, whether resulting from potential new government regulation, carbon taxes or consumer preferences could result in decreased demand for crude oil, natural gas and NGLs. Any decrease in demand for these products could consequently reduce demand for our services and could have a negative effect on our business.

Also, recent activism directed at shifting funding away from companies with energy-related assets could result in a reduction of funding for the energy sector overall, which could have an adverse effect on our ability to obtain external financing as well as negatively affect the cost of, and terms for, financing to fund capital expenditures or other aspects of our business.

Climate change may increase the frequency and severity of weather events that could result in severe personal injury, property and environmental damage, which could curtail our or our customers’ operations and otherwise materially adversely affect our cash flows.

Some scientists have concluded that increasing concentrations of GHG in the Earth’s atmosphere may produce climate changes that have significant weather–related effects, such as increased frequency and severity of storms, droughts, floods and other climatic events. If any of those effects were to occur, they could have an adverse effect on our assets and operations, including damages to our or our customers’ facilities and assets from powerful wind or rising waters. We may experience increased insurance costs, or difficulty obtaining adequate insurance coverage, for our assets in areas subject to more frequent severe weather. We may not be able to recoup these increased costs through the rates we charge our customers. Extreme weather events could cause damage to property or facilities that could exceed our insurance coverage and our business, financial condition and results of operations could be adversely affected.

Another possible consequence of climate change is increased volatility in seasonal temperatures. The market for natural gas and natural gas liquids is generally impacted by periods of colder weather and warmer weather, so any changes in climate could affect the market for those fuels, and thus demand for our services. Despite the use of the term “global warming” as a shorthand for climate change, some studies indicate that climate change could cause some areas to experience temperatures substantially colder than their historical averages. As a result, it is difficult to predict how the market for our services could be affected by increased temperature volatility.

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

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

Our operations, projects and growth opportunities require us to have strong relationships with various key stakeholders, including our shareholders, employees, suppliers, customers, local communities and others. We may face pressures from stakeholders, many of whom are increasingly focused on climate change, to prioritize sustainable energy practices, reduce our carbon footprint and promote sustainability while at the same time remaining a successfully operating public company. If we do not successfully manage expectations across these varied stakeholder interests, it

could erode our stakeholder trust and thereby affect our brand and reputation. Such erosion of confidence could negatively impact our business through decreased demand and growth opportunities, delays in projects, increased legal action and regulatory oversight, adverse press coverage and other adverse public statements, difficulty hiring and retaining top talent, difficulty obtaining necessary approvals and permits from governments and regulatory agencies on a timely basis and on acceptable terms, and difficulty securing investors and access to capital. The occurrence of any of the foregoing could have a material adverse effect on our business and financial condition.

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 2022 Transactions

During the year ended December 31, 2022, we completed sales of certain contract operations customer service agreements and approximately 770 compressors, comprising approximately 172,000 horsepower, used to provide compression services under those agreements, as well as other assets used to support the operations. We recorded an aggregate gain on the sales of $28.1 million. See Note 3 to our Financial Statements for additional information about these dispositions.

In April 2022, we agreed to acquire for cash a 25% equity interest in ECOTEC, a company specializing in methane emissions detection, monitoring and management. As of December 31, 2022, we own 22.7% of ECOTEC. We acquired the remaining equity interest of 2.3% in January 2023. See Note 11 to our Financial Statements for additional information about this investment.

Trends and Outlook

The key driver of our business is the production of U.S. oil and natural gas. Approximately 79% of our operating fleet is deployed for midstream natural gas gathering applications, with the remaining fleet being used in gas lift applications to enhance oil production. 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.

Domestic natural gas production generally occurs in either primarily natural gas basins, such as the Marcellus, Utica and Haynesville Shales, or in basins where natural gas is produced alongside oil, also known as “associated” gas, such as the Permian and Delaware Basins, Eagle Ford and the Mid–Continent. Relative stability in commodity prices over much of the past decade encouraged investment in domestic exploration and production and midstream infrastructure across the energy industry, particularly in the low–cost basins characterized by oil and associated natural gas production. The development of these basins producing both commodities has created additional incremental demand for natural gas compression over the recent past as it is a critical method to transport associated gas volumes or enhance oil production through gas lift.

Current Trends

According to the EIA Outlook, average U.S. oil and dry natural gas and production were as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Year Ended December 31,
​ | ​ | 2022 |  | 2021 |  | 2020
Average dry natural gas production (Bcf/d) |  | 98.0 |  | 93.6 |  | 91.3
Average oil production (MMb/d) |  | 11.9 |  | 11.2 |  | 11.3

​

Looking back to 2021, the economic recovery from the effects of the COVID–19 pandemic brought a rebound in energy demand around the globe; however, producers limited drilling and completion activity to achieve maintenance levels of production and cash flows in the course of the pandemic. In 2022, the rebound in energy demand triggered supply constraints and price spikes for multiple commodities. That, coupled with the conflict in Ukraine, increased market uncertainty and price spikes as the market and consumers balance supply security and affordability. Even given this uncertainty in the market, oil and natural gas production in 2022 continued to rebound, particularly natural gas production. The increases in production in 2022 resulted in strong demand for our compression services and we increased our investment in new fleet units. Our contract operations revenue and total operating horsepower increased 5% and 6%, respectively in 2022. Similar increases in demand in 2022 were seen in our aftermarket services business, where we experienced an increase of 26% in aftermarket services revenue in 2022.

Outlook

The EIA Outlook forecasts the following year–over–year changes:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31,
​ | ​ | 2023 | ​ | 2024 | ​
U.S. dry natural gas production |  | 2 | % | ​ | 2 | %
U.S. oil production |  | 5 | % | ​ | 3 | %
U.S. natural gas domestic consumption | ​ | (2) | % | ​ | (1) | %
Liquefied natural gas exports |  | 13 | % | ​ | 4 | %

The events of 2022 drove broad realization that a more diverse energy mix is needed to satisfy global energy demand and preserve energy security, making it a rewarding time to be in the business of transporting U.S. natural gas. The EIA Outlook expects natural gas production to continue to increase primarily in the Permian region in West Texas and Southeast New Mexico and in the Haynesville region in Louisiana and East Texas due to the expected completion of new pipeline infrastructure expansions in 2023 and 2024. Although the EIA expects natural gas production to increase, natural gas consumption is expected to decrease slightly, reflecting a decrease in the usage of natural gas in the electric power generation sector, as a result of increased power generation from renewables, partially offset by increased LNG exports and exports of natural gas via pipeline to Mexico.

We believe the outlook for the energy industry in the U.S. is positive. While we anticipate that the combination of commodity prices and demand may likely have a positive impact on activity levels in both the upstream and midstream sectors, we cannot predict the ultimate magnitude of that impact on our business and expect it to be varied across our operations, depending on the region, customer, nature of our services, contract term and other factors. However, we continue to believe that overall the long–term demand for our compression services will continue given the necessity of compression in facilitating the transportation and processing of natural gas.

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 natural gas industry and competition in the natural gas compression industry, we believe the following represent the key challenges and uncertainties we will face in the future.

Capital Requirements and the Availability of External Sources of Capital. We have funded a significant portion of our capital expenditures and acquisitions through borrowings under our 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 2023 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 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 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 disruptions 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. 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.

Increasing customer focus on free cash flow. Many of our customers have begun transitioning their business model to focus on sustainable free cash flow generation rather than growth, and the COVID–19 pandemic 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 expect this transition 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, restructuring charges, interest expense, debt extinguishment loss, gain on sale of assets, net, other (income) expense, net, and provision for (benefit from) income taxes. 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.

RESULTS OF OPERATIONS

Summary of Results

Revenue was $845.6 million and $781.5 million during the years ended December 31, 2022 and 2021, respectively. The increase in revenue was due to increased revenue from both our contract operations business and aftermarket services business. See “Contract Operations” and “Aftermarket Services” below for further details.

Net income was $44.3 million and $28.2 million during the years ended December 31, 2022 and 2021, respectively. The increase was primarily driven by a higher gross margin from our aftermarket services business, decreased depreciation and amortization expense and interest expense and an increased gain on sale of assets, net, partially offset by higher SG&A expenses and lower gross margin from our contract operations business and higher SG&A.

Revenue in our contract operations business increased primarily due to higher rates and an increase in average operating horsepower in response to improving market conditions, partially offset by the impact of the strategic dispositions in 2022 and 2021.

38

Table Archrock, Contents

Despite the increase in revenues, the decrease in gross margin in our contract operations business reflects the impact of a larger increase in cost of sales. Start–up, maintenance, lube oil and other operating expenses increased, driven by higher pricing throughout our supply chain, as well as increased volumes associated with unit redeployment as customer activity accelerated. Partially offsetting these cost increases was the decrease in expense attributable to the horsepower sold in 2022 and 2021.

Aftermarket Services

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ |  | ​ | ​
​ | ​ | Year Ended December 31, | ​ | Increase | ​

Gross margin | ​ | $ | 27,181 | ​ | $ | 18,719 |  | 45 | %
Gross margin percentage | ​ |  | 16 | % |  | 14 | % | 2 | %

Revenue in our aftermarket services business increased due to the increase in both service activities and sales of parts and components driven by increased customer demand during 2022 compared to 2021.

Gross margin increased due to the increase in revenue mentioned above, partially offset by the increase in cost of sales. The increase in cost of sales was primarily driven by increases in the cost associated with parts and labor.

Other expense (income), net | ​ | ​ | 1,845 | ​ | ​ | (4,707)

​

Selling, general and administrative. The increase in SG&A was primarily due to a $4.7 million increase in employee compensation costs, a $1.7 million increase in information technology expenses related to increased amortization expense of capitalized implementation costs and service agreements related to the substantial completion of our process and technology transformation project at the end of 2021, a $1.6 million increase in sales and use tax related to audit settlements and a $1.1 million increase in travel and meeting expenses.

Depreciation and amortization. The decrease in depreciation and amortization was primarily due the impact of assets reaching the end of their depreciable lives, compression and other asset sales and impairments and certain intangible assets reaching the end of their useful lives, partially offset by the increased depreciation and amortization expenses associated with fixed asset additions.

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 20 to our Financial Statements for further details.

​

Restructuring charges. Restructuring charges recorded in 2021 primarily related to reductions in headcount and costs to exit a facility no longer deemed economical for our business. We recorded no such restructuring charges during 2022. See Note 19 to our Financial Statements for further details.

Interest expense. The decrease in interest expense was primarily due to a decrease in the average outstanding balance of long–term debt and the $4.9 million write–off of unamortized deferred financing costs related to an amendment to our Credit Facility in 2021, which were partially offset by an increase in the weighted average effective interest rate.

Gain on sale of assets, net. The net gain on sales of assets during 2022 was the result of $28.1 million of gains recognized on sales of certain contract operations customer service agreements and approximately 770 compressors and $12.4 million of gains recognized on other compression and transportation asset sales.

The net gain on the sales of assets during 2021 was primarily the result of $19.0 million of gains recognized on sales of certain contract operations customer service agreements and approximately 875 compressors, $9.3 million of gains recognized on other compression asset sales and $3.3 million of gains recognized on other transportation and shop asset sales during the period.

Other expense (income), net. The change in other expense (income), net was primarily due to a $2.4 million decrease in insurance proceeds related to damages to facilities and compressors caused by Hurricane Ida, a $1.9 million unrealized change in the fair value of our investment in an unconsolidated affiliate and a $0.9 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. 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.

40

Table Archrock, Contents

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, 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 $146.3 million and $37.2 million during the years ended December 31, 2022 and 2021, respectively. The increase in growth capital expenditures from 2021 to 2022 was the result of increased investment in new compression equipment as a result of higher customer demand.

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 $84.2 million and $47.3 million during the years ended December 31, 2022 and 2021, respectively. The increase in maintenance capital expenditures from 2021 to 2022 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 $270.0 million to $295.0 million in capital expenditures during the year ended December 31, 2023, primarily consisting of approximately $180.0 million to $200.0 million for growth capital expenditures and approximately $75.0 million to $80.0 million for maintenance capital expenditures. We anticipate increased 2023 capital expenditures, particularly growth capital expenditures, as compared to 2022 due to increased investment in new compression equipment as a result of higher customer demand.

Dividends

On January 26, 2023, our Board of Directors declared a quarterly dividend of $0.15 per share of common stock, or approximately $23.6 million, which was paid on February 14, 2023 to stockholders of record at the close of business on February 7, 2023. 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.

Contractual Obligations

Our material contractual obligations as of December 31, 2022 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 $444.0 million, consisting of annual payments of approximately $103.5 million in 2023, approximately $100.7 million in 2024, and approximately $84.4 million or less in 2025 through 2028;

| • | Purchase commitments of $210.7 million, of which $178.0 million is due in 2023, that primarily consist of commitments to purchase fleet assets and information technology–related costs; and

| • | Operating lease payments of $21.4 million that are spread relatively evenly in 2023 through 2032.

In addition, we had $19.7 million of unrecognized tax benefits (including discontinued operations) recorded as liabilities related to uncertain tax positions and a liability of $2.1 million recorded for potential penalties and interest (including discontinued operations) related to these unrecognized tax benefits at December 31, 2022, which we are uncertain as to if or when such amounts may be settled.

Sources of Cash

Revolving Credit Facility

During the years ended December 31, 2022 and 2021, our Credit Facility had an average daily balance of $235.4 million and $295.3 million, respectively. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 6.9% and 2.6% at December 31, 2022 and 2021, respectively. As of December 31, 2022, there were $5.7 million of letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.4%.

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.

Our Credit Facility agreement requires that we meet certain financial ratios (see Note 14 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, $487.6 million of the $493.0 million of undrawn capacity was available for additional borrowings as of December 31, 2022. We were in compliance with all other covenants under our Credit Facility agreement.

Senior Notes

As of both December 31, 2022 and 2021, 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 to our Financial Statements for further details of these notes.

At–the–Market Continuous Equity Offering Program

Under our ATM Agreement, we may sell, from time to time, shares of our common stock having an aggregate offering 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 used the net proceeds of these offerings for general corporate purposes. During the years ended December 31, 2022 and 2021, we sold 447,020 and 357,148 shares of common stock, respectively, for net proceeds of $4.2 million and $3.4 million, respectively, pursuant to the ATM Agreement.

Other Sources of Cash

We received proceeds of $120.3 million and $112.9 million from business dispositions and other asset sales during the years ended December 31, 2022 and 2021, 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

Cash flows provided by (used in) each type of activity were as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​
​ | ​ | Year Ended December 31,
(in thousands) | ​ | 2022 |  | 2021
Net cash provided by (used in): | ​ | ​ |  |  | ​ |
Operating activities | ​ | $ | 203,450 | ​ | $ | 237,400
Investing activities | ​ |  | (130,916) | ​ |  | 16,107
Financing activities | ​ | ​ | (72,537) | ​ |  | (253,035)
Net (decrease) increase in cash and cash equivalents | ​ | $ | (3) | ​ | $ | 472

​

Operating Activities.

The decrease in net cash provided by operating activities was primarily due to increased cash outflow for cost of sales, contract costs, and SG&A, as well as decreased cash inflow from accounts receivable. Partially offsetting these decreases in operating cash were increased cash inflow from revenue and deferred revenue.

Investing Activities.

The change in net cash used in investing activities was primarily due to a $142.0 million increase in capital expenditures and a $14.7 million increase in our investment in unconsolidated affiliates, partially offset by a $7.4 million increase in proceeds from the sale of business and other assets.

43

Table Archrock, Contents

Financing Activities.

The decrease in net cash used in financing activities was primarily due to $16.8 million of net borrowings of long–term debt during 2022 compared with $158.5 million of net repayments of long–term debt during 2021, and a $3.1 million decrease in payments for settlements of interest rate swaps that include financing elements.

Critical Accounting Estimates

We describe our significant accounting policies more fully in Note 2 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 are carried at cost and depreciated using the straight–line basis over the estimated useful life of the asset. As of December 31, 2022, property, plant and equipment, net was $2.2 billion and depreciation expense was $155.4 million for the year ended December 31, 2022.

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, 2022, we recorded long–lived and other asset impairments of $21.4 million. We review long–lived assets, which include property, plant and equipment and intangibles assets 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.

For compressors that are removed from our active 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 20 and Note 25 to our Financial Statements for further details of our fleet asset impairments.

Table Archrock, Contents

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. 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 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.

GAAP 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 2 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 had previously used derivative instruments to manage our exposure to fluctuations in this variable interest rate; however, our interest rate swaps matured in March 2022, and all borrowings under the Credit Facility are now subject to variable interest rates.

A 1% increase in the effective interest rate on the outstanding balance under our Credit Facility at December 31, 2022 would have resulted in an annual increase in our interest expense of $2.5 million.

ITEM 9A. CONTROLS AND PROCEDURES

Management’s Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this 2022 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, 2022, 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, 2022.

The effectiveness of internal control over financial reporting as of December 31, 2022 was audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in its report found within this 2022 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.

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, 2022 and 2021, the related consolidated statements of operations, comprehensive income, equity, and cash flows, for each of the three years in the period ended December 31, 2022, 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, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, 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, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2023 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 20 to the financial statements.

Critical Audit Matter Description

F-1

​

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, 2022, the Company retired 145 units from the active fleet resulting in an asset impairment charge of $21.4 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.

Notes to Consolidated Financial Statements

​

NOTE 1. DESCRIPTION OF BUSINESS

We are an energy infrastructure company with a primary 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.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Our consolidated financial statements include the accounts of Archrock and its wholly–owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In the Notes to Consolidated Financial Statements, all dollar and share amounts in tabulations are in thousands of dollars and shares, respectively, unless otherwise noted.

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 amounts of assets and liabilities, revenues and 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 sued are reasonable.

Cash and Cash Equivalents

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

Accounts Receivable and Allowance for Credit Losses

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. Due to the short–term nature of our trade accounts receivable, we consider the amortized cost to be the same as the carrying value 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. 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.

Archrock, Inc.

Notes to Consolidated Financial Statements (continued)

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.

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 |  | 3 to 30 years
Buildings | ​ | 20 to 35 years
Transportation and shop equipment | ​ | 3 to 10 years
Computer hardware and software | ​ | 3 to 5 years
Other | ​ | 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.

Leases

We determine if an arrangement is a lease, or contains a lease, at inception and record the leases in our consolidated financial statements upon lease commencement, which is the date when the underlying asset is made available for use by the lessor. We recognize ROU assets and liabilities 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.

For contract operations service agreements in which we are a lessor, as the services nonlease component is predominant over the compression package lease component, we do not account for these agreements as operating leases.

Notes to Consolidated Financial Statements (continued)

Impairment of 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.

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.

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.

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.

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.

F-12

Archrock, Inc.

Notes to Consolidated Financial Statements (continued)

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.

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; therefore, our customers may be similarly affected by changes in economic and other conditions within the industry. We perform periodic evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness to manage this risk. We generally do not obtain collateral for trade receivables, but we may require payment in advance. 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.

During the years ended December 31, 2022, 2021 and 2020, no customers accounted for more than 10% of our consolidated revenues.

Accounting Standard Update Implemented

In December 2022, the FASB issued ASU No. 2022–06, Deferral of the Sunset Date of Reference Rate Reform (Topic 848). Topic 848 provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate (e.g., LIBOR) reform if certain criteria are met, for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. ASU 2022–06 deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. The ASU is effective as of December 21, 2022 through December 31, 2024. We adopted ASU 2022–06 during 2022, and the adoption did not and is currently not expected to have a material impact on our consolidated financial statements. We continue to evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis.

No other new accounting pronouncements issued or effective during 2022 have had or are expected to have a material impact on our consolidated financial statements.

NOTE 9. CONTRACT COSTS

We capitalize incremental costs to obtain a contract with a customer if we expect to recover those costs. Capitalized contract costs included commissions paid to our sales force to obtain contract operations contracts. As of December 31, 2022 and 2021, we had contract costs of $3.0 million and $2.6 million associated with sales commissions recorded in our consolidated balance sheets.

We also 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 we expect to recover those costs. Contract 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. As of December 31, 2022 and 2021, we had contract costs of $31.7 million and $22.8 million associated with freight and mobilization recorded in our consolidated balance sheets. 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 a contract asset.

These obtainment and fulfillment costs associated with our contract operations segment are amortized based on the transfer of service to which the assets relate, which is estimated to be 36 months based on average contract term, including anticipated renewals. We periodically assess whether the 36–month estimate fairly represents the average contract term and adjust as appropriate. Costs associated with sales commissions in our aftermarket services segment are expensed when paid, as the amortization period is less than one year. 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 a contract asset.

Costs associated with sales commissions in our contract operations segment are amortized to SG&A. During the years ended December 31, 2022, 2021 and 2020, we amortized $1.9 million, $2.2 million and $3.0 million, respectively, related to sales commissions. Contract costs associated with freight and mobilization are amortized to costs of sales (excluding depreciation and amortization). During the years ended December 31, 2022, 2021 and 2020, we amortized $17.3 million, $17.8 million and $23.6 million, respectively, related to freight and mobilization.

NOTE 10. HOSTING ARRANGEMENTS

We have hosting arrangements that are service contracts for cloud applications including our ERP, mobile workforce, telematics and inventory management tools.

Capitalized implementation costs and accumulated amortization related to our hosting arrangements that are service contracts are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​

​

These costs are included in other assets in our consolidated balance sheets. Amortization expense, which is recorded in SG&A in our consolidated statements of operations, was $2.0 million, $0.3 million and $0.3 million during the years ended December 31, 2022, 2021 and 2020, respectively.

During the year ended December 31, 2020, we impaired $1.7 million of capitalized implementation costs related to the hosting arrangements of the mobile workforce component of our project due to the termination of the agreement, which was included in long–lived and other asset impairment in our consolidated statements of operations.

NOTE 11. INVESTMENT IN UNCONSOLIDATED AFFILIATE

Investments in which we are deemed to exert significant influence, but not control, are accounted for using the equity method of accounting, except in cases where the fair value option is elected. For such investments where we have elected the fair value option, the election is irrevocable and is applied on an investment–by–investment basis at initial recognition.

In April 2022, we agreed to acquire for cash a 25% equity interest in ECOTEC, a company specializing in methane emissions detection, monitoring and management. We have elected the fair value option to account for this investment, and during the year ended December 31, 2022, we recognized an unrealized loss of $1.9 million related to the change in fair value of our investment (see Note 25). Changes in the fair value of this investment are recognized in other (income) expense, net in our consolidated statements of operations. As of December 31, 2022, our ownership interest in ECOTEC is 22.7%, which is included in other assets in our consolidated balance sheets. The remaining 2.3% interest was acquired in January 2023.

Credit Facility

As of December 31, 2022, our Credit Facility has an aggregate borrowing commitment of $750.0 million and will expire in November 2024 unless renewed or amended prior to that date. 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. We may use up to $50.0 million for swing line loans and an additional $50.0 million for letters of credit. As of December 31, 2022, there were $5.7 million letters of credit outstanding under the Credit Facility.

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 certain of our subsidiaries.

Borrowings under the Credit Facility bear interest at, based on our election, either a base rate or LIBOR, plus an applicable margin. 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%. Depending on our leverage ratio, the applicable margin varies (i) in the case of base rate loans, from 1.00% to 1.75% and (ii) in the case of LIBOR loans, from 2.00% to 2.75%. The weighted average annual interest rate on the outstanding balance under our Credit Facility, excluding the effect of interest rate swaps, was 6.9% and 2.6% at December 31, 2022 and 2021, respectively.

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 $1.9 million, $2.0 million and $2.0 million in commitment fees during 2022, 2021 and 2020, respectively.

Archrock, Inc.

Notes to Consolidated Financial Statements (continued)

As a result of the facility’s ratio requirements, $487.6 million of the $493.0 million of undrawn capacity was available for additional borrowings as of December 31, 2022.

As of December 31, 2022, the following consolidated financial ratios, as defined in our Credit Facility agreement, were required:

​

​ | ​ | ​
EBITDA to Interest Expense |  | 2.5 to 1.0
Senior Secured Debt to EBITDA |  | 3.0 to 1.0
Total Debt to EBITDA |  |
January 1, 2023 through September 30, 2023 | ​ | 5.50 to 1.0
Thereafter (1) |  | 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.

In addition to the financial covenants discussed above, 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, 2022, we were in compliance with all covenants under our Credit Facility agreement.

2027 Notes and 2028 Notes

Our 2027 Notes were issued under an indenture dated March 21, 2019 and mature on April 1, 2027. The notes were issued in a private offering at 100% of their face value and have an effective interest rate of 7.9%. We received net proceeds of $491.2 million after deducting issuance costs of $8.8 million.

Our 2028 Notes were issued under an indenture dated December 20, 2019 and mature on April 1, 2028. The 2028 Notes were issued in two private offerings of $500.0 million and $300.0 million in December 2019 and December 2020, respectively. 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 $491.8 million after deducting issuance costs of $8.2 million from our December 2019 offering and net proceeds of $309.9 million after deducting issuance costs of $4.7 million from our December 2020 offering.

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.

NOTE 15. COMMITMENTS AND CONTINGENCIES

Insurance Matters

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

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

In August 2021, Hurricane Ida made landfall in Louisiana, causing operational disruptions, damage to compressors and a temporary shutdown of facilities in Louisiana that negatively impacted our financial performance in the quarter. As of December 31, 2021, we had an insurance recovery of $2.8 million related to the facility and compressor damages, which we received in cash during the three months ended March 31, 2022. In September 2022, we received an additional $0.4 million related to business interruption insurance recovery proceeds.

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, 2022 and 2021, we accrued $3.9 million and $5.8 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.

During the years ended December 31, 2022 and 2021, certain of our sales and use tax audits advanced from the audit review phase to the contested hearing phase. As of both December 31, 2022 and 2021, we accrued $0.6 million for these audits.

F-21

Archrock, Inc.

Notes to Consolidated Financial Statements (continued)

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, 2022, which is included in our accrual for non–income–based tax audits discussed above.

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.

NOTE 16. STOCKHOLDERS’ 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 years ended December 31, 2022 and 2021, we sold 447,020 and 357,148 shares of common stock, respectively, for net proceeds of $4.2 million and $3.4 million, respectively, pursuant to the ATM Agreement.

Accumulated Other Comprehensive Loss

Components of comprehensive income (loss) are net income (loss) and all changes in equity during a period except those resulting from transactions with owners. Our accumulated other comprehensive loss consists of changes in the fair value of our interest rate swap derivative instruments, net of tax. See Note 24 for further details on our interest rate swap derivative instruments.

Performance Obligations

As of December 31, 2022, we had $310.5 million of remaining performance obligations related to our contract operations segment, which will be recognized through 2027 as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

We do not disclose the aggregate transaction price for the remaining performance obligations for aftermarket services as there are no contracts with customers with an original contract term that is greater than one year.

NOTE 18. STOCK–BASED COMPENSATION

The 2020 Plan and the 2013 Plan both provide 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 our employees, directors and consultants. 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.

As of December 31, 2022, the maximum number of shares of common stock available for issuance under the 2020 Plan is 8,500,000, and 5.9 million shares remain available for grant. 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. Our policy is to issue new shares when restricted stock units and performance–based restricted stock units are vested. We account for forfeitures as they occur.

F-24

Archrock, Inc.

Notes to Consolidated Financial Statements (continued)

Both the 2020 Plan and the 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, 2022, 2021 and 2020, we withheld 283,024 shares valued at $2.4 million, 283,972 shares valued at $2.5 million and 236,752 shares valued at $1.8 million, respectively, to cover tax withholding.

Restricted Stock Awards and Performance–Based Restricted Stock Units

Grants of restricted stock are subject to forfeiture, restrictions on transfer and certain other conditions until vesting, which generally occurs in three equal installments following the date of grant. Compensation expense is recognized 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.

Grants of performance–based restricted stock units are three–year equity settled awards linked to the performance of our common stock. The awards also include dividend equivalent rights that accumulate during the vesting period.

The vesting of the performance–based restricted stock units is dependent of the satisfaction of a combination of certain service–related conditions and 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 final number of shares of common stock issuable upon vesting can range from 0% to 200% of the initial grant depending on the level of achievement as determined by the Compensation Committee of our Board of Directors.

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 assumptions that were used to estimate the fair value of our performance–based stock units are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31, | ​
​ | ​ | 2022 | ​ | 2021 | ​ | 2020 | ​
Remaining performance period as of grant date (in years) |  | ​ | 2.9 |  | ​ | 2.8 |  | ​ | 2.9 |
Risk-free interest rate used |  | ​ | 1.4 | % | ​ | 0.3 | % | ​ | 1.4 | %
Grant-date fair value | ​ | $ | 11.96 | ​ | $ | 14.30 | ​ | $ | 11.33 | ​

​

The grant date fair value of the restricted stock and performance–based restricted stock units granted during the years ended December 31, 2022, 2021 and 2020 was $14.3 million, $12.1 million and $11.9 million, respectively. The fair value of the restricted stock and performance–based restricted stock units vested during the years ended December 31, 2022, 2021 and 2020 was $9.3 million, $8.5 million and $6.6 million, respectively.

As of December 31, 2022, we expect $12.7 million of unrecognized compensation cost related to our non–vested restricted stock and performance–based restricted stock units to be recognized over the weighted–average period of 1.8 years.

Cash Settled Performance Units

Grants of cash–settled performance units vest at the end of the three year vesting period and are payable in an amount of cash equivalent to the value of our common stock at the vesting date for each unit vested. These awards are subject to one of more performance conditions and are accounted for as liability awards with expense based on the fair value measured at the end of each reporting period. These awards also include dividend equivalent rights that accumulated during the vesting period. At the end of each reporting period, the Compensation Committee of our Board of Directors approves the determination of achievement for each performance measure, which can range from 0% to 200%.

Activity related to our cash–settled performance units is as follows:

​

​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | Weighted
​ | ​ | ​ | ​ | Average
​ | ​ | ​ | ​ | Grant Date

Non-vested cash-settled performance units, December 31, 2022 |  | 509 | ​ | $ | 9.27

​

The grant date fair value of the cash settled performance units granted during the years ended December 31, 2022, 2021 and 2020 was $2.5 million, $2.3 million and $1.8 million, respectively. Cash paid upon vesting of these cash settled performance units during the years ended December 31, 2022, 2021 and 2020 was $1.2 million, $0.6 million and $0.5 million, respectively.

As of December 31, 2022, we expect $3.0 million of unrecognized compensation cost related to our non–vested liability awards to be recognized over the weighted–average period of 1.9 years.

Employee Stock Purchase Plan

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 at a price equal to 85% to 100% of the fair market value of the stock as defined by the plan. 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 lesser. Our ESPP is compensatory and, as a result, we record an expense in our consolidated statements of operations related to the ESPP.

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 1.0 million. As of December 31, 2022, 429,250 shares remained available for purchase under the ESPP.

Directors’ Stock and Deferral Plan

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. In this case, we issue restricted stock units and the rights to receive dividends or dividend equivalents is accrued and paid when the shares are issued.

There are 100,000 shares reserved under the DSDP and, as of December 31, 2022, 37,771 shares remained available to be issued under the plan.

Stock–Based Compensation Expense

Stock–based compensation expense is as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31,
​ | ​ | 2022 |  | 2021 |  | 2020

NOTE 19. 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 $4.9 million, $4.4 million and $5.6 million during the years ended December 31, 2022, 2021 and 2020, respectively.

NOTE 20. LONG–LIVED AND OTHER ASSET IMPAIRMENT

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:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31,
​ | ​ | 2022 |  | 2021 |  | 2020
Idle compressors retired from the active fleet | ​ | ​ | 145 |  | ​ | 230 |  | ​ | 730

Impairment recorded on idle compressors retired from the active fleet | ​ | $ | 21,431 | ​ | $ | 21,208 | ​ | $ | 77,590

​

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 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.

Other Impairment

During the year ended December 31, 2020, $1.7 million of capitalized implementation and unamortized prepaid costs related to the mobile workforce component of our process and technology transformation project was impaired. See Note 10 for further details.

NOTE 21. RESTRUCTURING CHARGES

In response to the decreased activity level of our customers that resulted from the COVID–19 pandemic, we recorded pandemic restructuring charges for severance costs of $1.7 million and $5.3 million during the years ended December 31, 2021 and 2020, respectively. We do not expect to incur additional material costs under this restructuring plan.

During the year ended December 31, 2021, management approved and initiated a plan to exit a facility no longer deemed economical for our business, and we incurred $0.9 million of costs to complete the exit of the facility. We do not expect to incur additional material costs under this restructuring plan.

Notes to Consolidated Financial Statements (continued)

During the year ended December 31, 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. Management also approved a plan to dispose of certain non–core properties, and we incurred $1.5 million of costs as a result of these property disposals. No additional charges will be incurred under this restructuring plan.

Deferred income tax balances are the direct effect of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the taxes are actually paid or recovered. The tax effects of our temporary differences that gave rise to deferred tax assets and deferred tax liabilities were as follows:

(2) | The 2022 net deferred tax assets are reflected in our consolidated balance sheets as deferred tax assets of $33.4 million and $47.9 million, respectively, and deferred tax liabilities of $0.9 million and $1.1 million, respectively.

Both the 2022 and 2021 balances are based on a U.S. federal tax rate of 21%.

Tax Attributes and Valuation Allowances

Changes in our valuation allowance are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31,
​ | ​ | 2022 |  | 2021 |  | 2020

​

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.

F-31

Archrock, Inc.

Notes to Consolidated Financial Statements (continued)

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.

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, interest expense limitation 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, 2022, we had U.S. federal and state NOL carryforwards of $848.5 million and $314.8 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 2029 and 2023, respectively, though $629.2 million of the U.S. federal and $169.9 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 $0.6 million and $0.7 million as of December 31, 2022 and 2021, respectively.

At December 31, 2022, we had a U.S. federal tax credit carryforward of $3.0 million. If not used, the federal tax credit carryforward will begin to expire in 2037.

As of December 31, 2022, we had U.S. federal and state interest expense limitation carryforwards of $86.4 million and $26.5 million, respectively, included in our interest expense limitation deferred tax asset that are available to offset future taxable income. These carryforwards have no expiration.

Unrecognized Tax Benefits

Changes in our unrecognized tax benefits (including discontinued operations) are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31,
​ | ​ | 2022 |  | 2021 |  | 2020

Ending balance | ​ | $ | 19,651 | ​ | $ | 19,594 | ​ | $ | 18,892

​

We had $19.7 million, $19.6 million and $18.9 million of unrecognized tax benefits at December 31, 2022, 2021 and 2020, respectively, of which $1.1 million, $2.1 million and $2.9 million, respectively, would affect the effective tax rate if recognized and $7.9 million, $7.9 million and $7.9 million, respectively, would be reflected in income from discontinued operations, net of tax if recognized.

Archrock, Inc.

Notes to Consolidated Financial Statements (continued)

We recorded $2.1 million, $2.2 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, 2022, 2021 and 2020, 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 no potential expenses or releases of interest or penalties in our consolidated statements of operations during 2022, $0.1 million of potential interest expense and penalties during 2021, and releases of $0.1 million during 2020.

Subject to the provisions of our tax matters agreement with Exterran Corporation, both parties agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin–off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing. As of both December 31, 2022 and 2021, we recorded an indemnification asset (including penalties and interest) of $7.9 million, which is related to unrecognized tax benefits in our consolidated balance sheets (see Note 26).

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.

As of December 31, 2022, we believe it is reasonably possible that $2.7 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to December 31, 2023 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.

Impact of New Legislation

​

On August 16, 2022, President Biden signed into law the Inflation Reduction Act (Public Law Number 117–169). The legislation is expected to have an immaterial impact to our effective tax rate.

NOTE 23. NET INCOME (LOSS) PER COMMON 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.

NOTE 24. DERIVATIVES AND HEDGING

Prior to the expiration of our interest rate swaps in March 2022, we used derivative instruments to manage our exposure to fluctuations in the variable interest rate of our Credit Facility. We do not use derivative instruments for trading or other speculative purposes.

We had entered into three interest rate swaps with an aggregate notional amount of $300.0 million to offset changes in the expected cash flows due to fluctuations in the associated variable interest rates and designated them as cash flow hedges.

In 2021, we dedesignated one of the interest rate swaps with a $125.0 million notional value. At the time of dedesignation, the fair value of this interest rate swap was a liability of $1.6 million. The associated amount in accumulated other comprehensive loss related to this interest rate swap was amortized into interest expense over the remaining term of the swap through its expiration in March 2022. Changes in the fair value of this interest rate swap subsequent to dedesignation and prior to expiration were recorded in interest expense, the same consolidated statement of operations line item to which the earnings effect of the hedged item was recorded.

The remaining interest rate swaps had a $175.0 million notional value and were designated as (highly effective) cash flow hedging instruments until their expiration. Changes in the fair value of these interest rate swaps were recognized as a component of other comprehensive income (loss) until the hedged transactions affected earnings. At that time, amounts were reclassified into earnings to interest expense, the same consolidated statement of operations line item to which the earnings effect of the hedged items were recorded.

NOTE 25. 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 markets 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 markets makers.

| ● | Level 3 – model–derived valuation in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those 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

Investment in ECOTEC

As of December 31, 2022, we owned a 22.7% equity interest in ECOTEC (see Note 11). We have elected the fair value option to account for this investment. The fair value determination of this investment primarily consisted of unobservable inputs, which creates uncertainty in the measurement of fair value as of the reporting date. The significant unobservable inputs used in the fair value measurement, which was valued through an average of an income approach (discounted cash flow method) and a market approach (guideline public company method), are the WACC and the revenue multiples. Significant increases (decreases) in these inputs in isolation would result in a significantly higher (lower) fair value measurement. As of December 31, 2022, the fair value of our investment in ECOTEC is $12.8 million.

This fair value measurement is classified as Level 3. The significant unobservable inputs are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Significant Unobservable Inputs | ​ | ​ | Range | ​ | ​ | Median
Valuation technique: |  | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Balance at December 31 | ​ | $ | 12,803

(1) | Included in other expense (income) in our consolidated statements of operations.

Interest Rate Swaps

As of December 31, 2021, the fair value of our interest rate swaps was a liability of $1.3 million. Prior to their expiration in the first quarter of 2022, our interest rate swaps were valued quarterly based on the income approach (discounted cash flows) using market observable inputs, including LIBOR forward curves. These fair value measurements were classified as Level 2.

​

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Compressors

During the years ended December 31, 2022 and 2021, we recorded nonrecurring fair value measurements related to our idle compressors (see Note 20). 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.

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 was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | December 31,
​ | ​ | 2022 | ​ | 2021
Carrying amount of fixed rate debt (1) | ​ | $ | 1,297,084 | ​ | $ | 1,296,325
Fair value of fixed rate debt | ​ |  | 1,214,000 | ​ |  | 1,361,000

NOTE 28. SEGMENT INFORMATION

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, defined as revenue less cost of sales (excluding depreciation and amortization) for each segment. Segment revenue includes only sales to external customers.
