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 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 2022 Form 10–K and those set forth from time to time in our filings with 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.

Notes to Condensed Consolidated Financial Statements

1. Description of Business and Basis of Presentation

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, in terms of total compression fleet horsepower, to customers in the energy 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.

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by GAAP. Therefore, this information should be read in conjunction with our consolidated financial statements and notes contained in our 2022 Form 10-K. The information furnished herein reflects all adjustments that are, in the opinion of management, of a normal recurring nature and considered necessary for a fair statement of the results of the interim periods reported. All intercompany balances and transactions have been eliminated in consolidation. Operating results for the nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.

2. Recent Accounting Developments

Accounting Standards Updates Not Yet Implemented

Business Combinations – Joint Venture Formations

In August 2023, the FASB issued ASU 2023-05, to reduce diversity in practice and provide decision-useful information to a joint venture’s investors by requiring that a joint venture apply a new basis of accounting upon formation. By applying a new basis of accounting, a joint venture will recognize and initially measure its assets and liabilities at fair value, with exceptions to fair value measurement that are consistent with the business combinations guidance, on the date of formation. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. Additionally, a joint venture that was formed before January 1, 2025, may elect to apply the amendments retrospectively if it has sufficient information to do so. Early adoption is permitted in any interim or annual period in which financial statements have not been issued or been made available for issuance, either prospectively or retrospectively. We expect that the adoption of ASU 2023-05 will have no impact on our consolidated financial statements.

5. 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.

As of September 30, 2023, our ownership interest in ECOTEC, a company specializing in methane detection, monitoring and management, is 25% and included in other assets in our unaudited condensed consolidated balance sheets. For greater transparency, we have elected the fair value option for this investment.

Changes in the fair value of this investment are recognized in other expense (income), net in our unaudited condensed consolidated statements of operations. See Note 14 (“Fair Value Measurements”) for further details on fair value accounting.

Notes to Condensed Consolidated Financial Statements (continued)

As of September 30, 2023, there were $4.5 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.4%. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 7.9% and 6.9% at September 30, 2023 and December 31, 2022, respectively. We incurred $0.4 million and $0.5 million of commitment fees on the daily unused amount of the Credit Facility during the three months ended September 30, 2023 and 2022, respectively, and $1.3 million and $1.5 million during the nine months ended September 30, 2023 and 2022, respectively.

As of September 30, 2023, we were in compliance with all covenants under our Credit Facility agreement. Additionally, all undrawn capacity on our Credit Facility was available for borrowings as of September 30, 2023.

Amended and Restated Credit Agreement

On May 16, 2023, we amended and restated our Credit Facility to, among other things:

●

extend the maturity date of the Credit Facility from November 8, 2024 to May 16, 2028 (or December 2, 2026 or December 3, 2027 if any portion of 2027 Senior Notes and 2028 Senior Notes, respectively, remain outstanding at such date);

●

change the referenced rate from LIBOR to SOFR so that borrowings under the Credit Facility bear interest at, based on our election, either a base rate or SOFR, plus an applicable margin;

●

increase the portion of the Credit Facility available for the issuance of swing line loans from $50.0 million to $75.0 million.

We incurred $6.0 million in transaction costs related to the Amended and Restated Credit Agreement, which were included in other assets in our condensed consolidated balance sheets and are being amortized over the remaining term of the Credit Facility. In addition, we wrote off $1.0 million of unamortized deferred financing costs as a result of the Amended and Restated Credit Agreement, which was recorded to interest expense in our condensed consolidated statements of operations during the nine months ended September 30, 2023.

7. 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.

Notes to Condensed Consolidated Financial Statements (continued)

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, 2023 and December 31, 2022, we had $4.1 million and $3.9 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.

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 September 30, 2023 and December 31, 2022, we had $0.6 million accrued for these audits.

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.

8. Stockholders’ Equity

2023 Share Repurchase Program

On April 27, 2023, our Board of Directors authorized a share repurchase program that allows us to repurchase up to $50.0 million of outstanding common stock. Under the 2023 Share Repurchase Program, shares of our common stock may be repurchased periodically, including in the open market, privately negotiated transactions, or otherwise in accordance with applicable federal securities laws, at any time until April 27, 2024. The actual timing, manner, number, and value of shares repurchased under the program will be determined by us at our discretion.

The following table summarizes shares repurchased under the 2023 Share Repurchase Program during the three and nine months ended September 30, 2023:


	Three Months Ended		Nine Months Ended

Performance Obligations

As of September 30, 2023, we had $431.7 million of remaining performance obligations related to our contract operations segment, which will be recognized through 2028 as follows:


(in thousands)	2023		2024		2025		2026		2027		2028		Total
Remaining performance obligations	$	117,864	$	176,902	$	90,951	$	31,648	$	9,672	$	4,620	$	431,657

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 September 30, 2023 and December 31, 2022, our receivables from contracts with customers, net of allowance for credit losses, were $124.8 million and $111.9 million, respectively.

Allowance for Credit Losses

Our allowance for credit losses balance changed as follows during the nine months ended September 30, 2023:


(in thousands)
Balance at beginning of period	$	1,674
Benefit from credit losses		(234)
Write-offs charged against allowance		(452)
Balance at end of period	$	988

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, 2023 and December 31, 2022, our contract liabilities were $7.7 million and $8.0 million, respectively.

During the nine months ended September 30, 2023, we deferred revenue of $10.7 million and recognized $11.0 million as revenue. The revenue recognized during the period primarily related to freight billings and milestone billings on aftermarket services.

10. 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.

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.

Table of Contents

Archrock, Inc.

Notes to Condensed Consolidated Financial Statements (continued)

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 in our contract operations segment:


	Three Months Ended				Nine Months Ended
	September 30,				September 30,

See Note 14 (“Fair Value Measurements”) for further details on fair value accounting.

11. Restructuring Charges

During the first quarter of 2023, a plan to further streamline our organization and more fully align our teams to improve our customer service and profitability was approved by management. We do not expect to incur additional restructuring charges related to these restructuring activities.

The following table presents the changes to our accrued liability balance related to restructuring charges during the nine months ended September 30, 2023:

12. 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, 2023 differed significantly from our statutory rate primarily due to state taxes, unrecognized tax benefits and the limitation on executive compensation.

Unrecognized Tax Benefits

As of September 30, 2023, we believe it is reasonably possible that $2.8 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to September 30, 2024 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.

13. Earnings Per Common Share

Basic earnings per common share is computed using the two–class method, which is an earnings allocation formula that determines net income 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 earnings per common share is determined by dividing net income, 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 earnings per common share is computed using the weighted average number of common shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding performance–based restricted stock units and stock to be issued pursuant to our ESPP unless their effect would have been anti–dilutive.

Archrock, Inc.

Notes to Condensed Consolidated Financial Statements (continued)

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:

14. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

As of September 30, 2023, we own a 25% equity interest in ECOTEC. The fair value is determined using an average of the income approach that includes the use of a discounted cash flow model, and the market approach that includes the financial metrics of comparable public companies under the guideline public company method. The determination of this investment primarily consisted of unobservable inputs, which creates uncertainty in the measurement of fair value as of the reporting date. Significant increases (decreases) in these inputs in isolation would result in a significantly higher (lower) fair value measurement. As of September 30, 2023, the fair value of our investment in ECOTEC was $12.8 million.

This fair value measurement is classified as Level 3. The significant unobservable inputs used in the fair value measurement are the WACC and the revenue multiples. Additional quantitative information related to the significant unobservable inputs are as follows:


	Significant Unobservable Inputs		Range	Median
Valuation technique:
Discounted cash flow	WACC	0% - 17.4%		10.0%
Guideline public company	Revenue multiple	1.6x - 10x		4.0x

See Note 5 (“Investment in Unconsolidated Affiliate”) for further details.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

During the nine months ended September 30, 2023, we recorded nonrecurring fair value measurements related to our idle compressors. Our estimate of the compressors’ fair value was primarily based on the expected net sale proceeds compared 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 2023 and 2022 was as follows:


(in thousands)	September 30, 2023		December 31, 2022
Impaired compressors	$	1,036	$	1,961

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, 2023	$0 - $310 per horsepower	$51 per horsepower
As of December 31, 2022	$0 - $621 per horsepower	$47 per horsepower

(1)	Calculated based on an estimated discount for market liquidity of 35% and 51% as of September 30, 2023 and December 31, 2022, respectively.

See Note 10 (“Long-Lived and Other Asset Impairments”) for further details.

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.

(1) Carrying amounts are shown net of unamortized premium and deferred financing costs. See Note 6 (“Long-Term Debt”).

15. Related Party Transactions

Old Ocean Reserves, an affiliate of our customer Hilcorp, had the right to designate one director to serve on our Board of Directors as long as Old Ocean Reserves or its successors (together with its affiliates) owned at least 7.5% of our outstanding common stock. This right terminated in September 2023 when Old Ocean Reserves ownership of our outstanding common stock fell below 7.5%.

Revenue from Hilcorp was $8.9 million and $9.2 million during the three months ended September 30, 2023 and 2022, respectively, and $26.7 million and $27.8 million during the nine months ended September 30, 2023 and 2022, respectively. Accounts receivable, net due from Hilcorp was $3.2 million and $3.0 million as of September 30, 2023 and December 31, 2022, respectively.

16. Segment Information

We manage our business segments primarily based on the type of product or service provided. We have two segments: contract operations and aftermarket services. Our contract operations segment primarily provides natural gas compression services to meet specific customer requirements. Our 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. All of our operations are located in the U.S.

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.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited Financial Statements and the notes thereto included in this Form 10-Q and in conjunction with our 2022 Form 10-K.

OVERVIEW

We are an energy infrastructure company with a pure–play focus on midstream natural gas compression. We are the leading provider of natural gas compression services, in terms of total compression fleet horsepower, to customers in the energy 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 contract operations services primarily include 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.

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.

Table of Contents

Gross margin has certain material limitations associated with its use as compared to net income. 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 expense (income), 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.

The following table reconciles net income to gross margin:

RESULTS OF OPERATIONS

Summary of Results

Revenue was $253.4 million and $213.7 million during the three months ended September 30, 2023 and 2022, respectively, and $730.7 million and $626.7 million during the nine months ended September 30, 2023 and 2022, respectively. The increase in consolidated revenue was primarily due to increased revenue from both our contract operations business and aftermarket services business during the three and nine months ended September 30, 2023. See “Contract Operations” and “Aftermarket Services” below for further details.

Net income was $30.9 million and $15.4 million during the three months ended September 30, 2023 and 2022, respectively. The increase was primarily driven by higher gross margin from both our contract operations business and aftermarket services business and decreases in SG&A and long-lived and other asset impairment expense. These changes were partially offset by a decrease in the gain on sale of assets and increases in our provision for income taxes, interest expense and depreciation and amortization expense.

Net income was $72.0 million and $33.8 million during the nine months ended September 30, 2023 and 2022, respectively. The increase was primarily driven by higher gross margin from both our contract operations business and aftermarket services business and decreases in long-lived and other asset impairment expense and SG&A. These changes were partially offset by a decrease in the gain on sale of assets and increases in our provision for income taxes, interest expense, unrealized change in fair value of our investment in an unconsolidated affiliate and restructuring charges.

(1)	Defined as gross margin divided by revenue.

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

Gross margin percentage increased primarily due to an increase in revenue which exceeded the increase in cost of sales. Cost of sales for the three months ended September 30, 2023 includes an increase of $2.4 million for sales tax as a result of a change in tax compliance for sales tax associated with contract operations cost of sales. Prior to 2023, amounts were recognized in SG&A. Further, maintenance 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.

Table of Contents

Selling, general and administrative. The decrease in SG&A was primarily due to a decrease of $2.2 million for sales tax as a result of a change in tax compliance for sales tax associated with contract operations cost of sales. Beginning in 2023, amounts are recognized in contract operations cost of sales. Further, SG&A for the three months ended September 30, 2023 includes a $0.7 million decrease in professional expense and a $0.4 million decrease in employee compensation expense, partially offset by a $1.9 million increase in long-term performance-based incentive compensation expense.

Depreciation and amortization. The increase in depreciation and amortization expense was primarily due to fixed assets additions and accelerated depreciation associated with certain assets. These increases were partially offset by a decrease in depreciation expense associated with assets reaching the end of their depreciable lives, the impact of compression and other asset sales, and long-lived asset impairments.

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, 2023 and 2022, we recognized $2.9 million and $4.1 million, respectively, of impairment charges to write down these compressors to their fair value. See Note 10 (“Long-Lived Asset and Other Impairments”) for further details on 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,
(dollars in thousands)	2023		2022
Idle compressors retired from the active fleet		30		25
Horsepower of idle compressors retired from the active fleet		16,000		23,000
Impairment recorded on idle compressors retired from the active fleet	$	2,922	$	4,149

Restructuring charges. Restructuring charges of $0.6 million during the three months ended September 30, 2023 consisted of severance costs related to our restructuring activities. See Note 11 (“Restructuring Charges”) for further details on these restructuring charges.

Interest expense. The increase in interest expense was due to an increase in interest rates and a higher average outstanding balance of long–term debt, partially offset by an increase in capitalized interest.

Gain on sale of assets, net. The decrease in gain on sale of assets was primarily due to gains of $3.2 million on compression asset sales during the three months ended September 30, 2023, compared to gains of $12.7 million on compression asset sales during the three months ended September 30, 2022.

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 three months ended September 30, 2023 compared with the three months ended September 30, 2022.

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 $295 million in capital expenditures during 2023, primarily consisting of approximately $200 million for growth capital expenditures and approximately $79 million for maintenance capital expenditures. While market activity continues to be strong, we currently anticipate reducing growth capital expenditures to approximately $160 million in 2024 which reflects the capital discipline needed to support free cash flow generation after dividends.

Dividends

On October 26, 2023, our Board of Directors declared a quarterly dividend of $0.155 per share of common stock to be paid on November 14, 2023 to stockholders of record at the close of business on November 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.

During the nine months ended September 30, 2023 and 2022, our Credit Facility had an average debt balance of $294.5 million and $228.9 million, respectively. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 7.9% and 6.9% at September 30, 2023 and December 31, 2022, respectively. As of September 30, 2023, there were $4.5 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.4%.

As of September 30, 2023, we were in compliance with all covenants under our Credit Facility. Additionally, all undrawn capacity on our Credit Facility was available for borrowings as of September 30, 2023.

Cash Flows

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


	Nine Months Ended
	September 30,
(in thousands)	2023		2022
Net cash provided by (used in):
Operating activities	$	238,468	$	166,332

Financing activities		(31,395)		(99,313)
Net (decrease) increase in cash and cash equivalents	$	(1,084)	$	473

Operating Activities

The increase in net cash provided by operating activities was primarily due to increased cash inflows from gross margin and accounts receivable, partially offset by changes in accounts payable and other liabilities and deferred revenue.

Table of Contents

Investing Activities

The increase in net cash used in investing activities was primarily due to a $90.9 million increase in capital expenditures and a $99.8 million decrease in proceeds from the sale of business, partially offset by a $40.3 million increase in proceeds from sales of property, plant and equipment and a $10.0 million decrease in investments in non-consolidated affiliates.

Financing Activities

The decrease in net cash used in financing activities was primarily due to an $88.2 million increase in net borrowings of long-term debt, partially offset by $6.5 million of common stock purchased under the 2023 Share Repurchase Program, a $5.7 million payment for debt issuance costs related to the Amended and Restated Credit Agreement and a $3.9 million increase in dividends paid to stockholders.

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. A 1% increase in the effective interest rate on our Credit Facility’s outstanding balance at September 30, 2023 would have resulted in an annual increase in our interest expense of $3.1 million.

Basis of Presentation	The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by GAAP. Therefore, this information should be read in conjunction with our consolidated financial statements and notes contained in our 2022 Form 10-K. The information furnished herein reflects all adjustments that are, in the opinion of management, of a normal recurring nature and considered necessary for a fair statement of the results of the interim periods reported. All intercompany balances and transactions have been eliminated in consolidation. Operating results for the nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.
Accounting Standards Updates Not Yet Implemented	Accounting Standards Updates Not Yet Implemented Business Combinations – Joint Venture Formations In August 2023, the FASB issued ASU 2023-05, to reduce diversity in practice and provide decision-useful information to a joint venture’s investors by requiring that a joint venture apply a new basis of accounting upon formation. By applying a new basis of accounting, a joint venture will recognize and initially measure its assets and liabilities at fair value, with exceptions to fair value measurement that are consistent with the business combinations guidance, on the date of formation. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. Additionally, a joint venture that was formed before January 1, 2025, may elect to apply the amendments retrospectively if it has sufficient information to do so. Early adoption is permitted in any interim or annual period in which financial statements have not been issued or been made available for issuance, either prospectively or retrospectively. We expect that the adoption of ASU 2023-05 will have no impact on our consolidated financial statements.
