FORWARD–LOOKING STATEMENTS

​

This Quarterly Report on Form 10–Q (this “Form 10–Q”) contains “forward–looking statements” intended to qualify for the safe harbors from liability established by the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact contained in this Form 10–Q are forward–looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including, without limitation, our business growth strategy and projected costs; future financial position; the sufficiency of available cash flows to fund continuing operations and pay dividends; the expected amount of our capital expenditures; anticipated cost savings; future revenue, gross margin and other financial or operational measures related to our business; the future value of our equipment; and plans and objectives of our management for our future operations. You can identify many of these statements by words such as “believe,” “expect,” “intend,” “project,” “anticipate,” “estimate,” “will continue” or similar words or the negative thereof.

​

Such forward–looking statements are subject to various risks and uncertainties that could cause actual results to differ materially from those anticipated as of the date of this Form 10–Q. Although we believe that the expectations reflected in these forward–looking statements are based on reasonable assumptions, no assurance can be given that these expectations will prove to be correct. Known material factors that could cause our actual results to differ materially from the expectations reflected in these forward–looking statements include the risk factors described in our Annual Report on Form 10–K for the year ended December 31, 2021 (the “Form 10–K) and those set forth from time to time in our filings with the United States Securities and Exchange Commission (the “SEC”), which are available through our website at www.archrock.com and through the SEC’s website at www.sec.gov.

​

All forward–looking statements included in this Form 10–Q are based on information available to us on the date of this Form 10–Q. Except as required by law, we undertake no obligation to publicly update or revise any forward–looking statement, whether as a result of new information, future events or otherwise. All subsequent written and oral forward–looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained throughout this Form 10–Q.

NOTE 1. GENERAL

​

Description of Business

​

Archrock, Inc. (individually and together with its wholly owned subsidiaries, “we,” “our” or us”) is 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 energy industry throughout the United States (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. DISPOSITIONS

​

In September 2022, we completed the sale of certain contract operations customer service agreements and approximately 390 compressors, comprising approximately 100,000 horsepower, used to provide compression services under those agreements, as well as other assets used to support the operations. We allocated customer–related and contract–based intangible assets based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We received cash consideration of $44.3 million for the sale and recorded a gain on the sale of $11.5 million during the three months and nine months ended September 30, 2022.

​

In May 2022, we completed the sale of certain contract operations customer service agreements and approximately 380 compressors, comprising approximately 70,000 horsepower, used to provide compression services under those agreements, as well as other assets used to support the operations. We allocated customer–related and contract–based intangible assets based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We received cash consideration of $55.5 million for the sale and recorded a gain on the sale of $16.7 million during the nine months ended September 30, 2022.

NOTE 5. EQUITY INVESTMENTS

​

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 International Holdings, LLC. (“ECOTEC”), a company specializing in methane emissions detection, monitoring and management. We have elected the fair value option to account for this investment (see Note 16). As of September 30, 2022, our ownership interest in ECOTEC is 19%, which is included in Other assets in our unaudited condensed consolidated balance sheets.

​

Changes in the fair value of this investment are recognized in Other (income) expense, net in our unaudited condensed consolidated statements of operations.

​

​

NOTE 6. HOSTING ARRANGEMENTS

​

We have hosting arrangements that are service contracts related to the cloud migration of our Enterprise Resource Planning (“ERP”) system and cloud services for our mobile workforce, telematics and inventory management tools.

​

As of September 30, 2022 and December 31, 2021, we had $15.1 million and $12.7 million, respectively, of capitalized implementation costs related to these hosting arrangements included in Other assets in our unaudited condensed consolidated balance sheets. Accumulated amortization was $2.1 million and $0.7 million as of September 30, 2022 and December 31, 2021, respectively.

​

Included in Selling, general and administrative in our unaudited condensed consolidated statements of operations is amortization of $0.6 million and $0.1 million during the three months ended September 30, 2022 and 2021, respectively, and $1.5 million and $0.3 million during the nine months ended September 30, 2022 and 2021, respectively.

​

Our $750.0 million asset–based revolving Credit Facility, as amended (the “Credit Facility”), matures in November 2024. As of September 30, 2022, there were $5.8 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.4%. The weighted average annual interest rate on the outstanding balance under our Credit Facility, excluding the effect of interest rate swaps, was 5.5% and 2.6% at September 30, 2022 and December 31, 2021, respectively. We incurred $0.5 million of commitment fees on the daily unused amount of the Credit Facility in each of the three months ended September 30, 2022 and 2021 and $1.5 million in each of the nine months ended September 30, 2022 and 2021.

​

As of September 30, 2022, we were in compliance with all covenants under our Credit Facility agreement. As a result of the Credit Facility’s financial ratio requirements, $486.4 million of the $542.2 million of undrawn capacity was available for additional borrowings as of September 30, 2022.

​

In February 2021, we amended our Credit Facility to, among other things, reduce the aggregate revolving commitment from $1.25 billion to $750.0 million and adjust certain financial ratios. We wrote off $4.9 million of unamortized deferred financing costs as a result of the amendment, which was recorded to interest expense in our unaudited condensed consolidated statements of operations during the nine months ended September 30, 2021.

​

NOTE 8. 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 caused operational disruptions, damage to compressors and a temporary shutdown of facilities in Louisiana that negatively impacted our financial performance. At December 31, 2021, we had an insurance recovery receivable 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 $0.4 million of business interruption insurance recovery proceeds, which resolved the remainder of our insurance claims related to Hurricane Ida.

​

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 September 30, 2022 and December 31, 2021, we had $3.9 million and $5.8 million, respectively, accrued for the outcomes of non–income–based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We believe the likelihood is remote that the impact of potential unasserted claims from non–income–based tax audits could be material to our consolidated financial position, but it is possible that the resolution of future audits could be material to our consolidated results of operations or cash flows.

​

In 2021, one of our sales and use tax audits advanced from the audit review phase to the contested hearing phase. As of both September 30, 2022 and December 31, 2021, we had $0.6 million accrued for this audit.

​

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 9. STOCKHOLDERS’ EQUITY

​

Equity Distribution Agreement

​

During the nine months ended September 30, 2022, we sold 447,020 shares of common stock for net proceeds of $4.2 million pursuant to an Equity Distribution agreement, dated February 23, 2021, entered into with Wells Fargo Securities, LLC and BofA Securities, Inc., as sales agents, relating to the at–the–market offer and sale of shares of our common stock from time to time (the “Equity Distribution Agreement”). During the nine months ended September 30, 2021, we sold 357,148 shares of common stock under this program for net proceeds of $3.4 million.

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 15 for further details on our interest rate swap derivative instruments.

Performance Obligations

​

As of September 30, 2022, we had $282.3 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.

​

Contract Assets and Liabilities

​

Contract Assets

​

As of September 30, 2022 and December 31, 2021, our receivables from contracts with customers, net of allowance for credit losses, were $118.9 million and $84.7 million, respectively.

​

Allowance for Credit Losses

​

Trade accounts receivable are due from companies of varying size engaged principally in oil and natural gas activities throughout the U.S. We review the financial condition of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of the products and services we provide and the terms of our customer agreements.

15

Table of Contents

Archrock, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements (continued)

​

​

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

​

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

​

Our allowance for credit losses balance changed as follows during the nine months ended September 30, 2022:

​

​ | ​ | ​ | ​
Balance at December 31, 2021 |  | $ | 2,152
Provision for credit losses | ​ | ​ | (28)
Write-offs charged against allowance | ​ | ​ | (637)
Balance at September 30, 2022 | ​ | $ | 1,487

​

Contract Liabilities

​

Freight billings to customers for the transport of compression assets, customer–specified modifications of compression assets and milestone billings on aftermarket services often result in a contract liability. As of September 30, 2022 and December 31, 2021, our contract liabilities were $8.3 million and $4.4 million, respectively.

​

During the nine months ended September 30, 2022, we deferred revenue of $19.6 million and recognized deferred revenue of $15.7 million. The revenue recognized during the period primarily related to freight billings and milestone billings on aftermarket services.

​

NOTE 11. STOCK–BASED COMPENSATION

​

We grant various forms of stock–based compensation to our employees and non–employee directors. These stock–based awards can consist of stock options, stock appreciation rights, restricted stock awards, restricted stock units (“RSUs”), performance–based RSUs, other stock–based awards and dividend equivalent rights. We recognize stock–based compensation expense related to restricted stock awards, RSUs, performance–based RSUs and shares issued under our ESPP.

As of September 30, 2022, there was $17.1 million of unrecognized stock–based compensation expense which is expected to be recognized over a weighted average period of 1.9 years.

​

NOTE 12. LONG–LIVED AND OTHER ASSET IMPAIRMENT

​

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

​

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.

​

See Note 16 for additional information.

​

NOTE 13. INCOME TAXES

​

Valuation Allowance

​

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 net operating loss, interest 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.

​

Effective Tax Rate

​

The year-to-date effective tax rate for the nine months ended September 30, 2022 differed significantly from our statutory rate primarily due to unrecognized tax benefits and the limitation on executive compensation.

​

Unrecognized Tax Benefits

​

As of September 30, 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 September 30, 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). This legislation is expected to have an immaterial impact to our unaudited condensed consolidated financial statements.

​

NOTE 14. EARNINGS 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 common shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding options, performance–based RSUs and stock to be issued pursuant to our ESPP unless their effect would have been anti–dilutive.

​

The following table shows the calculation of net income attributable to common stockholders, which is used in the calculation of basic and diluted earnings per common share, potential shares of common stock that were included in computing diluted earnings per common share and the potential shares of common stock issuable that were excluded from computing diluted earnings per common share as their inclusion would have been anti–dilutive:

NOTE 15. DERIVATIVES AND HEDGING

​

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

​

In March 2022, our $300.0 million notional value of interest rate swaps expired. We previously entered into these swaps to offset changes in expected cash flows due to fluctuations in the associated variable interest rates and designated them as cash flow hedges. There was no nonperformance by any counterparty during the terms of the interest rate swaps and no collateral was posted for the instruments.

​

19

Table of Contents

Archrock, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements (continued)

​

Prior to expiration, during the third quarter of 2021, we dedesignated $125.0 million notional value of our interest rate swaps. The fair value of this interest rate swap immediately prior to dedesignation was a liability of $1.6 million. The associated amount in accumulated other comprehensive loss related to this interest rate swap was amortized into interest expense over the remaining term of the swap through March 2022. Changes in the fair value of the dedesignated interest rate swap after dedesignation and prior to expiration were recorded in interest expense.

​

The remaining $175.0 million notional value of our interest rate swaps were designated as (highly effective) cash flow hedging instruments until their expiration. Changes in the fair value of cash flow hedging instruments are recognized as a component of other comprehensive income (loss) until the hedged transaction affects earnings. At that time, amounts are reclassified into earnings to interest expense, the same statement of operations line item to which the earnings effect of the hedged item is recorded. Cash flows from derivatives designated as hedges are classified in our unaudited condensed consolidated statements of cash flows under the same category as the cash flows from the underlying assets, liabilities or anticipated transactions unless the derivative contract contains a significant financing element, in which case, the cash settlements for those derivatives are classified as cash flows from financing activities.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

​

Investment in ECOTEC

​

During the nine months ended September 30, 2022, we acquired a 19% equity interest in ECOTEC. We have elected the fair value option to account for this investment. The investment is valued at its transaction price, unless and until there is a significant change in the investment, such as an impairment or an additional investment. The investment’s fair value is reviewed periodically and is classified as a Level 3 measurement. As of September 30, 2022, the fair value of our investment in ECOTEC was as follows:

Interest Rate Swaps

​

Prior to their expiration in the first quarter of 2022, our interest rate swap derivative instruments 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. The following table presents our derivative position measured at fair value on a recurring basis, with pricing levels as of the date of valuation:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | September 30, 2022 | ​ | December 31, 2021
Derivative liabilities | ​ | $ | — | ​ | $ | 1,250

​

​

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

​

During the three months and nine months ended September 30, 2022, we recorded nonrecurring fair value measurements of $4.1 million and $16.2 million, respectively, related to our idle compressors (see Note 12). Our estimate of the compressors’ fair value was primarily based on the expected net sale proceeds compared with 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. The fair value of our compressors impaired in 2022 and 2021 was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | September 30, 2022 |  | December 31, 2021
Impaired compressors | ​ | $ | 1,548 | ​ | $ | 4,380

​

​

These fair value measurements are classified as Level 3. The significant unobservable inputs used to develop the above fair value measurements were weighted by the relative fair value of the compressors being measured. Additional quantitative information related to our significant unobservable inputs follows:

​

​ | ​ | ​ | ​ | ​
​ |  | Range |  | Weighted Average (1)
Estimated net sale proceeds: | ​ | ​ | ​ | ​
As of September 30, 2022 | ​ | $0 - $621 per horsepower | ​ | $44 per horsepower
As of December 31, 2021 | ​ | $0 - $621 per horsepower | ​ | $35 per horsepower

(1) | Calculated based on an estimated discount for market liquidity of 56% and 64% as of September 30, 2022 and December 31, 2021, respectively.

​

Other Financial Instruments

​

The carrying amounts of our cash, accounts receivable and accounts payable approximate fair value due to the short–term nature of these instruments.

​

The carrying amount of borrowings outstanding under our Credit Facility approximates fair value due to the variable interest rate. The measurement of 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:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | September 30, 2022 |  | December 31, 2021
Carrying amount of fixed rate debt (1) | ​ | $ | 1,296,895 | ​ | $ | 1,296,325
Fair value of fixed rate debt | ​ |  | 1,155,760 | ​ |  | 1,361,000

(1) | Carrying amounts are shown net of unamortized premium and deferred financing costs. See Note 7.

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 selling, general & administrative (“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, gain on sale of assets, net, other (income) expense, net and provision for 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 $213.7 million and $195.2 million during the three months ended September 30, 2022 and 2021, respectively, and $626.7 million and $586.2 million during the nine months ended September 30, 2022 and 2021, respectively. The increases in consolidated revenue during these periods were primarily due to increased revenue from both our contract operations business and aftermarket services business. See “Contract Operations” and “Aftermarket Services” below for further details.

​

25

Table of Contents

Net income was $15.4 million and $9.3 million during the three months ended September 30, 2022 and 2021, respectively. The increase was primarily driven by a higher gross margin from both our aftermarket services business and our contract operations business and decreased depreciation and amortization expense, partially offset by increased SG&A and lower gain on sale of assets, net.

​

Net income was $33.8 million and $22.2 million during the nine months ended September 30, 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 a lower gross margin from our contract operations business and higher SG&A.

Gross margin percentage (1) | ​ |  | 58 | % |  | 61 | % | (3) | %

(1) | Defined as gross margin divided by revenue.

​

Revenue in our contract operations business increased primarily due to an increase in average operating horsepower and higher rates in response to improving market conditions, partially offset by the impact of the strategic dispositions in 2021 and 2022. Average operating horsepower for the three months ended September 30, 2022 increased when compared with the three months ended September 30, 2021 before adjusting for the dispositions.

​

Despite the increase in revenue, the increase in gross margin in our contract operations business was partially offset by our 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 2021 and 2022.

​

Selling, general and administrative. The increase in SG&A was primarily due to a $1.1 million increase in employee compensation costs and a $0.9 million increase in information technology expense related to increased amortization of capitalized implementation costs and increased service agreement costs related to the substantial completion of our process and technology transformation project at the end of 2021.

​

Depreciation and amortization. The decrease in depreciation and amortization expense was primarily due to the impact of assets reaching the end of their depreciable lives and compression and other asset sales, partially offset by the impact of 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. We also evaluate for impairment our idle units that have been culled from our compression fleet in prior years and are available for sale. During the three months ended September 30, 2022 and 2021, we recognized $4.2 million and $5.1 million, respectively, of impairment charges to write down these compressors to their fair value. See Note 12 in our Notes to Unaudited Condensed Consolidated Financial Statements for additional information about these impairment charges. The following table presents the results of our compression fleet impairment review, as recorded in our contract operations segment:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Three Months Ended
​ | ​ | September 30,
​ |  | 2022 |  | 2021
Idle compressors retired from the active fleet |  | ​ | 25 |  | ​ | 60
Horsepower of idle compressors retired from the active fleet |  | ​ | 23,000 |  | ​ | 24,000
Impairment recorded on idle compressors retired from the active fleet | ​ | $ | 4,149 | ​ | $ | 5,120

​

Interest expense. The decrease in interest expense was due to a lower average outstanding balance of long–term debt, partially offset by a higher average interest rate as a result of the expiration of our interest rate swaps in the first quarter of 2022.

​

Gain on sale of assets, net. The net gain on sale of assets during the three months ended September 30, 2022 was primarily the result of the $11.5 million of gain recognized on the September 2022 disposition of assets and gains of $1.2 million recognized on sales of other compression, transportation and shop assets during the period.

​

The net gain on sale of assets during the three months ended September 30, 2021 was primarily the result of the $13.0 million of gain recognized on the July 2021 disposition of assets and gains of $2.2 million recognized in on other compression asset sales during the period.

​

Average operating horsepower for the nine months ended September 30, 2022 increased when compared with the nine months ended September 30, 2021 before adjusting for the dispositions.

​

Despite the increase in revenue, 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.

​

Selling, general and administrative. The increase in SG&A was primarily due to a $2.0 million increase in sales and use tax resulting from audit settlements reached during the nine months ended September 30, 2021, a $1.7 million increase in information technology expense related to increased amortization of capitalized implementation costs and increased service agreement costs related to the substantial completion of our process and technology transformation project at the end of 2021, a $0.9 million increase in employee compensation costs and a $0.9 million increase in higher travel and meeting expenses.

​

Depreciation and amortization. The decrease in depreciation and amortization expense was primarily due to the impact of assets reaching the end of their depreciable lives, compression and other asset sales and impairments, partially offset by the impact of 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. We also evaluate for impairment our idle units that have been culled from our compression fleet in prior years and are available for sale. During the nine months ended September 30, 2022 and 2021, we recognized $16.2 million and $15.2 million, respectively, of impairment charges to write down these compressors to their fair value. See Note 12 in our Notes to Unaudited Condensed Consolidated Financial Statements for additional information about these impairment charges. The following table presents the results of our compression fleet impairment review, as recorded in our contract operations segment:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Nine Months Ended
​ | ​ | September 30,
​ |  | 2022 |  | 2021
Idle compressors retired from the active fleet |  | ​ | 100 |  | ​ | 175
Horsepower of idle compressors retired from the active fleet |  | ​ | 80,000 |  | ​ | 61,000
Impairment recorded on idle compressors retired from the active fleet | ​ | $ | 16,205 | ​ | $ | 14,964

​

Interest expense. The decrease in interest expense was due to the $4.9 million write–off of unamortized deferred financing costs related to the amendment of our Credit Facility in the first quarter of 2021 and a lower average outstanding balance of long–term debt, offset by a higher average interest rate as a result of the expiration of our interest rate swaps in the first quarter of 2022.

​

Gain on sale of assets, net. The net gain on sale of assets during the nine months ended September 30, 2022 was primarily the result of the $28.2 million of gains recognized on the May 2022 and September 2022 dispositions of assets and gains of $5.6 million recognized on sales of other compression, transportation and shop assets during the period.

​

The net gain on sale of assets during the nine months ended September 30, 2021 was primarily the result of the $19.0 million of gains recognized on the February 2021 and July 2021 dispositions of assets and gains of $8.6 million recognized on other compression asset sales during the period.

Provision for income taxes. The increase in provision for income taxes was primarily due to the tax effect of the increase in book income during the nine months ended September 30, 2022 compared with the nine months ended September 30, 2021.

​

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.

​

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

​

Cash Requirements

​

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

| • | operating expenses, namely employee compensation and benefits and inventory and lube oil purchases;

| • | growth capital expenditures;

| • | maintenance capital expenditures;

| • | interest on our outstanding debt obligations; and

| • | dividend payments to our stockholders.

​

Capital Expenditures

​

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

​

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.

​

Projected Capital Expenditures. We currently plan to spend approximately $230 million to $235 million in capital expenditures during 2022, primarily consisting of approximately $150 million for growth capital expenditures and approximately $70 million to $75 million for maintenance capital expenditures. The increase in 2022 capital expenditures, particularly growth capital expenditures, as compared to 2021 is due to increased investment in new compression equipment as a result of higher customer demand.

Dividends

​

On October 27, 2022, our Board of Directors declared a quarterly dividend of $0.145 per share of common stock to be paid on November 15, 2022 to stockholders of record at the close of business on November 8, 2022. Any future determinations to pay cash dividends to our stockholders will be at the discretion of our Board of Directors and will be dependent upon our financial condition, results of operations and credit and loan agreements in effect at that time and other factors deemed relevant by our Board of Directors.

​

Sources of Cash

​

Revolving Credit Facility

​

During the nine months ended September 30, 2022 and 2021, our Credit Facility had an average debt balance of $228.9 million and $310.9 million, respectively. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 5.5% and 2.6% at September 30, 2022 and December 31, 2021, respectively. As of September 30, 2022, there were $5.8 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.4%.

​

As of September 30, 2022, we were in compliance with all covenants under our Credit Facility. As a result of the facility’s financial ratio requirements, $486.4 million of the $542.2 million of undrawn capacity was available for additional borrowings as of September 30, 2022.

​

Equity Distribution Agreement

​

During the nine months ended September 30, 2022 and 2021, we sold 447,020 and 357,148 shares of common stock for net proceeds of $4.2 million and $3.4 million, respectively, pursuant to the Equity Distribution Agreement.

​

Cash Flows

​

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

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Nine Months Ended
​ | ​ | September 30,
​ |  | 2022 |  | 2021
Net cash provided by (used in): |  | ​ |  |  | ​ |
Operating activities | ​ | $ | 166,332 | ​ | $ | 208,725
Investing activities | ​ |  | (66,546) | ​ |  | 37,854
Financing activities | ​ |  | (99,313) | ​ |  | (244,188)

​

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 (provided by) investing activities was primarily due to a $100.2 million increase in capital expenditures and the $12.0 million investment made in unconsolidated entities during the nine months ended September 30, 2022. These cash outflows were partially offset by an increase of $5.4 million in proceeds from business dispositions and other sales of property, plant and equipment and an increase of $2.4 million in insurance and other settlements.

​

Table of Contents

Financing Activities

​

The decrease in net cash used in financing activities was primarily due to $32.5 million of net repayments of long–term debt during the nine months ended September 30, 2022 compared with $173.0 million of net repayments of long–term debt during the nine months ended September 30, 2021.

​

​

​

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

​

We are exposed to market risks associated with changes in the variable interest rate of our Credit Facility. We have previously used derivative instruments to manage our exposure to fluctuation in this variable interest rate; however, our interest rate swaps expired in the first quarter of 2022, and all borrowings under our Credit Facility are now subject to variable interest rates.

​

A 1% increase in the effective interest rate on our Credit Facility’s outstanding balance at September 30, 2022 would have resulted in an annual increase in our interest expense of $2.0 million.

​

ITEM 4. CONTROLS AND PROCEDURES

​

This Item 4 includes information concerning the controls and controls evaluation referred to in the certifications of our Chief Executive Officer and Chief Financial Officer required by Rule 13a–14 of the Exchange Act included in this Form 10–Q as Exhibits 31.1 and 31.2.

​

Management’s Evaluation of Disclosure Controls and Procedures

​

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to management to allow timely decisions regarding required disclosures.

​

As of the end of the period covered by this Quarterly Report on Form 10-Q, 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 September 30, 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.

​

Changes in Internal Control over Financial Reporting

​

In the first quarter of 2022, we implemented a new ERP system, which replaced our existing core financial systems, resulting in changes to our financial close processes and procedures. As a result of the implementation, certain internal controls over financial reporting were automated, modified or implemented. While we believe the new ERP system will enhance our internal controls, there are inherent risks in implementing any new system, and we will continue to evaluate these control changes as part of our assessment of control design and effectiveness throughout 2022.

​

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

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

​

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.

​

ITEM 1A. RISK FACTORS

​

There have been no material changes or updates to the risk factors previously disclosed in our Form 10–K.
