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, adjusted 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 2023 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. These risk factors include, but are not limited to, inability to consummate the TOPS Acquisition; inability to achieve the expected benefits of the TOPS Acquisition and difficulties in integrating TOPS; risks of the acquisitions, including the TOPS Acquisition, to reduce our ability to make distributions to our common stockholders; risks related to pandemics and other public health crises; an increase in inflation; ongoing international conflicts and tensions; risks related to our operations; competitive pressures; inability to make acquisitions on economically acceptable terms; uncertainty to pay dividends in the future; risks related to a substantial amount of debt and our debt agreements; inability to access the capital and credit markets or borrow on affordable terms to obtain additional capital; inability to fund purchases of additional compression equipment; vulnerability to interest rate increases; uncertainty relating to the phasing out of LIBOR; erosion of the financial condition of our customers; risks related to the loss of our most significant customers; uncertainty of the renewals for our contract operations service agreements; risks related to losing management or operational personnel; dependence on particular suppliers and vulnerability to product shortages and price increases; information technology and cybersecurity risks; tax-related risks; legal and regulatory risks, including climate-related and environmental, social and governance risks.

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 primary focus on midstream natural gas compression. We are a premier 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 condensed 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 2023 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 six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.

2. Recent Accounting Developments

Accounting Standards Updates Not Yet Implemented

Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which will require significant additional disclosures, primarily focused on the disclosure of income taxes paid and the rate reconciliation table. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 and interim periods within fiscal years beginning after December 15, 2025, and should be applied on a prospective basis, with a retrospective option. Early adoption is permitted. We are evaluating the impact that the adoption of ASU 2023-09 will have on our consolidated financial statements and related disclosures.

Segment Reporting

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which will require disclosures of significant expenses for each reportable segment, as well as certain other disclosures to help investors understand how the chief operating decision maker evaluates segment expenses and operating results. ASU 2023-07 will also allow disclosure of multiple measures of segment profitability if those measures are used to allocate resources and assess performance. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and should be applied on a retrospective basis, unless impracticable. Early adoption is permitted. We are evaluating the impact that the adoption of ASU 2023-07 will have on our segment disclosures. We expect that the adoption of ASU 2023-07 will not have a material impact on our consolidated financial statements.

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.

3. Inventory

5. Investments in Unconsolidated Affiliates

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

In April 2022, we agreed to acquire for cash a 25% equity interest in ECOTEC, a company specializing in methane emissions detection, monitoring and management. We have elected the fair value option to account for this investment, and during the three and six months ended June 30, 2023, we recognized unrealized losses of $1.7 million and $2.0 million, respectively, related to the change in fair value of our investment (see Note 14 (“Fair Value Measurements”)). Changes in the fair value of this investment are recognized in other expense, net in our condensed consolidated statements of operations. As of June 30, 2024, our ownership interest in ECOTEC was 25%, which is included in other assets in our condensed consolidated balance sheets.

Notes to Condensed Consolidated Financial Statements (continued)

For ownership interests that are not accounted for under the equity method and that do not have readily determinable fair values, we have elected the fair value measurement alternative to record these investments at cost minus impairment, if any, including adjustments for observable price changes in orderly transactions for an identical or similar investment of the same issuer. Investments in equity securities measured using the fair value measurement alternative are reviewed for impairment or observable price changes in orderly transactions each reporting period.

In November 2023, we agreed to serve as the lead investor in a series A preferred financing round for Ionada, a global carbon capture technology company committed to reducing GHG emissions and creating a sustainable future. Ionada has developed a post-combustion carbon capture solution to reduce carbon dioxide emissions from various small to mid-sized industrial emitters in the energy, marine and e-fuels industries, among others. We have elected the fair value measurement alternative to account for this investment (see Note 14 (“Fair Value Measurements”)). Adjustments to the carrying value are recognized in other expense, net in our condensed consolidated statements of operations. As of June 30, 2024, the carrying value of our investment in Ionada was $4.3 million which includes our initial investment of $3.8 million; and our fully diluted ownership interest in Ionada was 10%, which is included in other assets in our condensed consolidated balance sheets. Subject to certain conditions, our ownership interest will increase to 24% over the next two years.

6. Long-Term Debt

Long-term debt was comprised of the following as of June 30, 2024, and December 31, 2023:

Long-term debt	$	1,608,956	$	1,584,869

As of June 30, 2024, there were $4.1 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.1%. The weighted average annual interest rate on the outstanding balance under the Credit Facility was 7.6% and 7.7% at June 30, 2024 and December 31, 2023, respectively. We incurred $0.4 million of commitment fees on the daily unused amount of the Credit Facility during each of the three months ended June 30, 2024 and 2023, and $0.9 million during each of the six months ended June 30, 2024 and 2023.

As of June 30, 2024, we were in compliance with all covenants under our Amended and Restated Credit Agreement. Additionally, all undrawn capacity on our Credit Facility was available for borrowings as of June 30, 2024.

Table of Contents

Archrock, Inc.

Notes to Condensed Consolidated Financial Statements (continued)

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 Notes and 2028 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; and

●

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

During the second quarter of 2023, 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, during the second quarter of 2023, 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 three and six months ended June 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.

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 June 30, 2024 and December 31, 2023, we had $4.3 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 each of June 30, 2024 and December 31, 2023, we accrued $0.6 million for these audits.

Table of Contents

Archrock, Inc.

Notes to Condensed Consolidated Financial Statements (continued)

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

Share Repurchases

Share Repurchase Program

On April 27, 2023, our Board of Directors authorized a share repurchase program that allowed us to repurchase up to $50.0 million of outstanding common stock. Under the 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. On April 25, 2024, our Board of Directors approved an extension of the Share Repurchase Program upon expiry of the current authorization on April 27, 2024, for an additional 24-month period. Through June 30, 2024, the Company had repurchased 833,346 common shares at an average price of $12.11 per share for an aggregate of $10.1 million. In connection with the extension, the Board of Directors replenished the amount of shares authorized for repurchase under the Share Repurchase Program, resulting in available capacity of $50.0 million. The actual timing, manner, number, and value of shares repurchased under the program will be determined by us at our discretion.

Shares Withheld to Cover

The 2020 Plan and 2013 Plan allow us to withhold shares upon vesting of restricted stock at the then-current market price to cover taxes required to be withheld on the vesting date.

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 June 30, 2024 and December 31, 2023, our receivables from contracts with customers, net of allowance for credit losses, were $108.3 million and $119.7 million, respectively.

Notes to Condensed Consolidated Financial Statements (continued)

Allowance for Credit Losses

Our allowance for credit losses balance changed as follows during the six months ended June 30, 2024:


(in thousands)
Balance at beginning of period	$	587
Provision for credit losses		5
Write-offs charged against allowance		(36)
Balance at end of period	$	556

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 June 30, 2024 and December 31, 2023, our contract liabilities were $7.7 million and $7.0 million, respectively.

During the six months ended June 30, 2024, we deferred revenue of $6.3 million and recognized $5.6 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.

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				Six Months Ended
	June 30,				June 30,

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. While we did not incur restructuring charges during the six months ended June 30, 2024, we expect to incur additional restructuring charges of $0.1 million related to these restructuring activities.

The following table presents restructuring charges incurred by segment:

Total restructuring costs	$	(85)	$	962

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 expense limitation and tax credit carryforwards. This may result in the need to record a valuation allowance against all or a portion of our deferred tax assets.

Effective Tax Rate

The year-to-date effective tax rate for the six months ended June 30, 2024 differed significantly from our statutory rate primarily due to state taxes, unrecognized tax benefits and the limitation on executive compensation offset by the benefit from equity-settled long term incentive compensation.

Table of Contents

Archrock, Inc.

Notes to Condensed Consolidated Financial Statements (continued)

Unrecognized Tax Benefits

As of June 30, 2024, we believe it is reasonably possible that $3.4 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to June 30, 2025 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 earnings 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.

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

Investment in ECOTEC

As of June 30, 2024, we owned a 25% equity interest in ECOTEC (see Note 5 (“Investments in Unconsolidated Affiliates”)). We have elected the fair value option to account for this investment. As of June 30, 2024, the fair value of our investment in ECOTEC was $14.9 million and is classified as Level 3.

The fair value determination of this investment primarily consisted of unobservable inputs, which creates uncertainty in the measurement of fair value as of the reporting date. The significant unobservable inputs used in the fair value measurement, which was valued through an average of an income approach (discounted cash flow method) and a market approach (guideline public company method), are the WACC and the revenue multiples. Significant increases (decreases) in these inputs in isolation would result in a significantly higher (lower) fair value measurement.

Additional quantitative information related to the significant unobservable inputs are as follows:

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Investment in Ionada

As of June 30, 2024, we had a fully diluted ownership equity interest in Ionada of 10% (see Note 5 (“Investments in Unconsolidated Affiliates”)). We have elected the fair value measurement alternative to account for this investment. As of June 30, 2024, the carrying value of our investment in Ionada was $4.3 million, which includes our initial investment of $3.8 million and cumulative transaction costs of $0.5 million. There have been no upward adjustments, impairments or downward adjustments to the carrying value of the investment. Subject to certain contractual conditions, we will invest, on the same terms and conditions as the initial investment, $1.2 million on November 1, 2024, $1.3 million on November 1, 2025, and $4.8 million prior to July 1, 2026, for a fully diluted ownership interest of 12%, 15% and 24%, respectively.

Compressors

During the six months ended June 30, 2024, 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. These fair value measurements are classified as Level 3. The fair value of our compressors impaired as of June 30, 2024 and December 31, 2023 was as follows:

16. Segment Information

We manage our business segments primarily based on the type of product or service provided. We have two segments that we operate within the U.S.: 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.

We evaluate the performance of our segments based on adjusted gross margin, defined as revenue less cost of sales, exclusive of 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 condensed consolidated financial statements and the notes thereto included in this Form 10-Q and in conjunction with our 2023 Form 10-K.

OVERVIEW

We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We are a premier 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 adjusted gross margin.

We define adjusted gross margin as total revenue less cost of sales, exclusive of depreciation and amortization. Adjusted 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, exclusive of depreciation and amortization, which are key components of our operations. We believe adjusted 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, adjusted gross margin should not be considered an alternative to, or more meaningful than, gross margin, net income (loss) or any other measure presented in accordance with GAAP. Our adjusted gross margin may not be comparable to a similarly-titled measure of other entities because other entities may not calculate adjusted gross margin in the same manner.

Table of Contents

Adjusted 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.

RESULTS OF OPERATIONS

Summary of Results

Revenue was $270.5 million and $247.5 million during the three months ended June 30, 2024, and 2023, respectively, and $539.0 million and $477.4 million during the six months ended June 30, 2024 and 2023, respectively. The increase in revenue was primarily due to increased revenue from our contract operations business during the three months ended June 30, 2024 and both our contract operations business and aftermarket services business during the six months ended June 30, 2024. See “Contract Operations” and “Aftermarket Services” below for further details.

Net income was $34.4 million and $24.7 million during the three months ended June 30, 2024, and 2023, respectively. The increase was primarily driven by higher adjusted gross margin from both our contract operations business and aftermarket services business. These changes were partially offset by increases in SG&A, depreciation and amortization expense, transaction-related costs and long-lived and other asset impairment, and a decrease in the unrealized change in the fair value of our investment in an unconsolidated affiliate.

Table of Contents

Net income was $75.0 million and $41.1 million during the six months ended June 30, 2024, and 2023, respectively. The increase was primarily driven by higher adjusted gross margin from both our contract operations business and aftermarket services business. These changes were partially offset by increases in SG&A, depreciation and amortization expense, transaction-related costs, long-lived and other asset impairment, and decreases in the gain on sale of assets and in the unrealized change in the fair value of our investment in an unconsolidated affiliate.

(1)	Defined as adjusted 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 higher utilization at Archrock and across our industry.

The increase in cost of sales, exclusive of depreciation and amortization, was primarily due to a $3.7 million increase in total employee compensation expense and a $1.1 million increase in parts expense. This increase was partially offset by a decrease of $1.9 million in startup expenses resulting from average horsepower utilization for the fleet at record levels as well as fewer unit stops.

Selling, general and administrative. The increase in SG&A included a $1.9 million increase in long-term incentive compensation expense, a $0.2 million increase in employee compensation expense and a $0.2 million increase in amortization of capitalized implementation costs, partially offset by a decrease of $0.3 million in legal and other professional fees.

Depreciation and amortization. The increase in depreciation and amortization expense was primarily due to fixed assets additions and accelerated depreciation associated with certain assets. The increase was 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 June 30, 2024 and 2023, we recognized $4.4 million and $2.9 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
	June 30,
(dollars in thousands)	2024		2023
Idle compressors retired from the active fleet		40		15
Horsepower of idle compressors retired from the active fleet		32,000		9,000
Impairment recorded on idle compressors retired from the active fleet	$	4,401	$	2,892

Interest expense. The decrease in interest expense was primarily due to the write-off of $1.0 million of unamortized deferred financing costs as a result of the Amended and Restated Credit Agreement during the three months ended June 30, 2023, and a lower average outstanding balance of long-term debt, partially offset by a decrease in capitalized interest and an increase in interest rates.

Transaction-related costs. We incurred $1.8 million of legal and other professional fees during the three months ended June 30, 2024 related to the TOPS Acquisition.

Gain on sale of assets, net. The decrease in gain on sale of assets was primarily due to gains of $0.3 million on compression asset sales and $0.3 million on transportation asset sales during the three months ended June 30, 2024, compared to gains of $0.6 million on compression asset sales and $0.4 million on other asset sales during the three months ended June 30, 2023.

Other expense, net. The increase in other expense, net was primarily due to a $1.7 million unrealized change in the fair value of our investment in an unconsolidated affiliate recognized during the three months ended June 30, 2023.

Provision for Income Taxes

The increase in provision for income taxes was primarily due to the tax effect of the increase in book income, offset by the reduction in valuation allowance during the three months ended June 30, 2024 compared with the three months ended June 30, 2023.

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 six months ended June 30, 2024 and 2023, we recognized $7.0 million and $5.5 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:


	Six Months Ended
	June 30,
(dollars in thousands)	2024		2023
Idle compressors retired from the active fleet		65		45
Horsepower of idle compressors retired from the active fleet		46,000		23,000
Impairment recorded on idle compressors retired from the active fleet	$	6,969	$	5,461

Restructuring charges. Restructuring charges of $1.0 million during the six months ended June 30, 2023 consisted of severance and consulting costs related to our restructuring activities. See Note 11 (“Restructuring Charges”) for further details on these restructuring charges.

Interest expense. The decrease in interest expense was primarily due to the write-off of $1.0 million of unamortized deferred financing costs as a result of the Amended and Restated Credit Agreement during the six months ended June 30, 2023, partially offset by a decrease in capitalized interest and an increase in interest rates.

Transaction-related costs. We incurred $1.8 million of legal and other professional fees during the six months ended June 30, 2024 related to the TOPS Acquisition.

Table of Contents

Gain on sale of assets, net. The decrease in gain on sale of assets was primarily due to gains of $2.5 million on compression asset sales and $0.4 million on transportation asset sales during the six months ended June 30, 2024 compared to gains of $3.9 million on compression asset sales and $0.8 million on transportation and other asset sales during the six months ended June 30, 2023.

Other expense, net. The increase in other expense, net was primarily due to a $2.0 million unrealized change in the fair value of our investment in an unconsolidated affiliate recognized during the six months ended June 30, 2023.

Provision for Income Taxes

The increase in provision for income taxes was primarily due to the tax effect of the increase in book income and the limitation on executive compensation offset by the benefit from equity-settled long term incentive compensation and reduction in valuation allowance during the six months ended June 30, 2024 compared with the six months ended June 30, 2023.

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, inventory and lube oil purchases;

•

growth capital expenditures;

•

maintenance capital expenditures;

•

interest on our outstanding debt obligations;

•

dividend payments to our stockholders; and

•

shares repurchased under the Share Repurchase Program and to cover taxes required to be withheld on the vesting date of long-term incentive grants to employees.

Table of Contents

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. While market activity continues to be strong, we currently anticipate reduced capital expenditures in 2024 compared to 2023, which supports free cash flow generation after dividends, and plan to spend approximately $290 million to $300 million in capital expenditures during 2024, primarily consisting of approximately $190 million for growth capital expenditures and approximately $80 million to $85 million for maintenance capital expenditures.

Dividends

On July 25, 2024, our Board of Directors declared a quarterly dividend of $0.165 per share of common stock to be paid on August 13, 2024 to stockholders of record at the close of business on August 6, 2024. 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

Credit Facility

During the six months ended June 30, 2024 and 2023, our Credit Facility had an average debt balance of $287.0 million and $282.5 million, respectively. The weighted average annual interest rate on the outstanding balance under the Credit Facility was 7.6% and 7.7% at June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024, there were $4.1 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.1%.

As of June 30, 2024, 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 June 30, 2024.

Cash Flows

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


	Six Months Ended
	June 30,
(in thousands)	2024		2023
Net cash provided by (used in):
Operating activities	$	208,353	$	118,398
Investing activities		(173,488)		(150,946)
Financing activities		(35,284)		32,175
Net decrease in cash and cash equivalents	$	(419)	$	(373)

Table of Contents

Operating Activities

The increase in net cash provided by operating activities was primarily due to increased cash inflows of $65.9 million from adjusted gross margin, excluding deferred revenue recognized in earnings and amortization of freight and mobilization charges, changes of $14.3 million in accounts receivable due to increased cash receipts from customers, $11.4 million in accounts payable and accrued liabilities due to a reduction in overall spend and timing of vendor invoice payments and $8.7 million of inventory as a result of improvement in the lead time for parts.

Investing Activities

The increase in net cash used in investing activities was primarily due to a $20.5 million decrease in proceeds from the sale of property, plant and equipment and a $3.6 million increase in capital expenditures, partially offset by a $1.9 million decrease in investments in non-consolidated affiliates.

Financing Activities

The change from net cash provided by financing activities to net cash used in financing activities was primarily due to a $66.9 million decrease in net borrowings of long-term debt, a $4.5 million increase in dividends paid to stockholders and a $2.7 million increase in taxes paid related to net share settlement of equity awards, partially offset by a $5.5 million decrease in payments of debt issuance costs and a $1.2 million increase in common stock purchased under the Share Repurchase Program.

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 June 30, 2024 would have resulted in an annual increase in our interest expense of $3.1 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 June 30, 2024, 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

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

ITEM 1. LEGAL PROCEEDINGS

ITEM 1A. RISK FACTORS

Other than the following items, there have been no material changes or updates to the risk factors previously disclosed in our 2023 Form 10-K.

Risks Related to the TOPS Acquisition

We may not consummate the TOPS Acquisition.

The TOPS Acquisition is subject to the satisfaction or waiver of customary closing conditions, and we cannot assure you that the TOPS Acquisition will be consummated in the anticipated time frame or at all. If one or more of the closing conditions are not satisfied, the TOPS Acquisition may not be completed. Some of these conditions are beyond our control, and we may elect not to take actions necessary to satisfy these conditions or to ensure that the TOPS Acquisition is not otherwise terminated. In addition, the purchase and sale agreement contains certain termination rights for both parties which, if exercised, will also result in the TOPS Acquisition not being consummated.

If the TOPS Acquisition is delayed, terminated or consummated on terms different than those described in the purchase and sale agreement, the market price of our common stock may decline to the extent that the price of our common stock reflects a market assumption that the TOPS Acquisition will be consummated on the terms described in the purchase and sale agreement or at all. Further, a failed transaction may result in negative publicity or a negative impression of us in the investment community and may affect our relationships with our business partners and the value of our common stock.

Under certain specified circumstances in which the purchase and sale agreement is terminated pursuant to its terms, Archrock ELT may be required to pay sellers a termination fee equal to $30.0 million or, in certain circumstances, sellers may be required to pay Archrock ELT a termination fee equal to $20.0 million. If the purchase and sale agreement is terminated under such circumstances, the termination fee Archrock ELT may be required to pay under the purchase and sale agreement may require us to use available cash that would have otherwise been available for general corporate purposes and other uses.

Table of Contents

We may not be able to achieve the expected benefits of the TOPS Acquisition. We may also encounter significant

difficulties in integrating TOPS.

Even if we consummate the TOPS Acquisition, we may not be able to achieve the expected benefits of the TOPS Acquisition. There can be no assurance that the TOPS Acquisition will be beneficial to us. We may not be able to integrate the assets acquired in the TOPS Acquisition without increases in costs or other difficulties. The integration of a business is a complex, costly and time-consuming process. As a result, we will be required to devote significant management attention and resources to integrating our business practices and operations with the business practices and operations of TOPS. The integration process may disrupt our business and, if implemented ineffectively, would restrict the full realization of the anticipated benefits from the TOPS Acquisition. The failure to meet the challenges involved in integrating TOPS and to realize the anticipated benefits of the TOPS Acquisition could have an adverse effect on our business, results of operations, financial condition and prospects, as well as the market price of our common stock. The challenges of integrating the operations of acquired businesses include, among others:

●

difficulties with the integration of the business of TOPS and workforce following the TOPS Acquisition;

●

conditions in the oil and natural gas industry, including the level of production of, demand for or price of oil or natural gas;

●

our reduced profit margins or the loss of market share resulting from competition or the introduction of competing technologies by other companies;

●

changes in economic or political conditions, including terrorism and legislative changes;

●

the inherent risks associated with our operations, such as equipment defects, impairments, malfunctions and natural disasters;

●

the risk that counterparties will not perform their obligations under our financial instruments;

●

the financial condition of our customers;

●

our ability to timely and cost-effectively obtain components necessary to conduct our business;

●

employment and workforce factors, including our ability to hire, train and retain key employees;

●

our ability to implement certain business and financial objectives, such as:

●

winning profitable new business;

●

growing our asset base and enhancing asset utilization;

●

integrating acquired businesses;

●

generating sufficient cash; and

●

accessing the capital markets at an acceptable cost;

●

liability related to the use of our services;

●

changes in governmental safety, health, environmental or other regulations, which could require us to make significant expenditures;

●

the effectiveness of our control environment, including the identification of control deficiencies; and

●

our level of indebtedness and ability to fund our business.

Many of these factors are outside of our control, and any one of them could result in increased costs and liabilities, decreases in the amount of expected revenue and earnings, and diversion of management’s time and energy, which could have a material adverse effect on our business, financial condition and results of operations. Further, additional unanticipated costs may be incurred in the integration of the acquired business.

The market price of our common stock may decline as a result of the TOPS Acquisition if, among other things, the integration of the properties to be acquired in the TOPS Acquisition is unsuccessful or transaction costs related to the TOPS Acquisition are greater than expected. The market price of our common stock may decline if we do not achieve the perceived benefits of the TOPS Acquisition as rapidly or to the extent anticipated by us or by securities market participants or if the effect of TOPS Acquisition on our business, results of operations or financial condition or prospects is not consistent with our expectations or those of securities market participants.

Table of Contents

Any acquisitions we complete, including the TOPS Acquisition, are subject to substantial risks that could reduce our ability to make distributions to our common stockholders.

Even if we do make acquisitions that we believe will increase the amount of cash available for distribution to our common stockholders, these acquisitions, including the TOPS Acquisition, may nevertheless result in a decrease in the amount of cash available for distribution to our common stockholders. Any acquisition, including the TOPS Acquisition, involves potential risks, including, among other things:

●

the assumption of unknown liabilities, losses or costs for which we are not indemnified or for which any indemnity we receive is inadequate;

●

our inability to obtain satisfactory title to the assets we acquire; and

●

the occurrence of other significant changes, such as impairment of long-lived assets, asset devaluation or restructuring charges.

Basis of Presentation and Significant Accounting Policies
Basis of Presentation	The accompanying unaudited condensed 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 2023 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 six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.
Accounting Standards Updates Implemented and Accounting Standards Updates Not Yet Implemented	Accounting Standards Updates Not Yet Implemented Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which will require significant additional disclosures, primarily focused on the disclosure of income taxes paid and the rate reconciliation table. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 and interim periods within fiscal years beginning after December 15, 2025, and should be applied on a prospective basis, with a retrospective option. Early adoption is permitted. We are evaluating the impact that the adoption of ASU 2023-09 will have on our consolidated financial statements and related disclosures. Segment Reporting In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which will require disclosures of significant expenses for each reportable segment, as well as certain other disclosures to help investors understand how the chief operating decision maker evaluates segment expenses and operating results. ASU 2023-07 will also allow disclosure of multiple measures of segment profitability if those measures are used to allocate resources and assess performance. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and should be applied on a retrospective basis, unless impracticable. Early adoption is permitted. We are evaluating the impact that the adoption of ASU 2023-07 will have on our segment disclosures. We expect that the adoption of ASU 2023-07 will not have a material impact on our consolidated financial statements. 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.
