Item 9A. Controls and Procedures Management’s Evaluation of Disclosure Controls and Procedures As of the end of the period covered by this Form 10–K, our principal executive officer and principal financial officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a–15(e) of the Exchange Act), which are designed to provide reasonable assurance that we are able to record, process, summarize and report the information required to be disclosed in our reports under the Exchange Act within the time periods specified in the rules and forms of the SEC. Based on the evaluation, as of December 31, 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. Management’s Annual Report on Internal Control Over Financial Reporting As required by Exchange Act Rules 13a–15(c) and 15d–15(c), our management, including the Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting. Management conducted an evaluation of the effectiveness of internal control over financial reporting based on the Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness as to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Based on the results of management’s evaluation described above, management concluded that our internal control over financial reporting was effective as of December 31, 2024. On August 30, 2024, we completed the TOPS Acquisition which was the acquisition of a privately-held company that was not subject to Section 404 of the Sarbanes-Oxley Act. As the TOPS Acquisition occurred during the third quarter of 2024, and TOPS was not previously subject to Section 404 of the Sarbanes-Oxley Act, management concluded there was insufficient time for management to complete its assessment of the internal controls over financial reporting related to TOPS, and, therefore, TOPS’s internal controls over financial reporting were excluded from this report on internal control over financial reporting. Our management with the participation of the Chief Executive Officer and Chief Financial Officer conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting excluding TOPS’ internal controls as of December 31, 2024 (covering approximately 94.3% of the revenue on the Consolidated Statements of Operations for the year ended December 31, 2024 and 70.2% of the total assets on the Consolidated Balance Sheets as of December 31, 2024) based on the Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on its evaluation, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2024. The effectiveness of internal control over financial reporting as of December 31, 2024 was audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in its report found within this Form 10–K. Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a–15(f) and 15d–15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ​ 51 Table of Contents ​ REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the shareholders and the Board of Directors of Archrock, Inc. Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Archrock, Inc. and subsidiaries (the “Company”) as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) the consolidated financial statements as of and for the year ended December 31, 2024, of the Company and our report dated February 25, 2025, expressed an unqualified opinion on those financial statements. As described in Management’s Annual Report on Internal Control Over Financial Reporting, appearing in Item 9A, management excluded from its assessment the internal control over financial reporting at TOPS which was acquired on August 30, 2024, and whose financial statements constitute 29.8% and 5.7% of total assets and revenue, respectively of the consolidated financial statement amounts as of and for the year ended December 31, 2024. Accordingly, our audit did not include the internal control over financial reporting at TOPS. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 52 Table of Contents ​ Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Archrock, Inc. and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive income, equity, and cash flows, for each of the three years in the period ended December 31, 2024, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2025, expressed an unqualified opinion on the Company’s internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. TOPS ACQUISITION - Refer to Note 4 and 18 to the financial statements. Critical Audit Matter Description F-1 Table of Contents The Company completed the acquisition of Total Operations and Production Services, LLC (TOPS) for cash consideration of $868.7 million and 6,873,650 shares of common stock with an acquisition date fair value of $139.1 million. Accordingly, the purchase price paid for assets acquired and liabilities assumed was allocated, based on respective fair value, to property, plant and equipment (including compressors) and other intangible assets. The method for determining respective fair value varied depending on the type of asset or liability and involved management making significant estimates related to assumptions such as future cash flows, discount rates, market data, projected revenue, and current market interest rates. Given the respective fair value determination of assets acquired and liabilities assumed requires management to make significant estimates related to assumptions such as future cash flows, discount rates, market data, projected revenue, and current market interest rates, performing audit procedures to evaluate the reasonableness of these assumptions required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to management's selection of a weighted average cost of capital, and the fair value of acquired property, plant and equipment and intangible assets for TOPS included the following, among others: • We tested the effectiveness of controls over the purchase price allocation, including management's controls over the assumptions used in the valuation of the property, plant and equipment and intangible assets, including estimating the fair value of the acquired property, plant and equipment and intangible assets, determination of the weighted average cost of capital, and reviewing the work of third-party specialists. • With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodology, (2) current market data, (3) cost to replace certain assets, and (4) assumptions used in the discounted cash flows, including testing the mathematical accuracy of the calculation, and developing a range of independent estimates and comparing our estimates to those used by management. • We assessed the reasonableness of management’s projections of contract revenue by comparing the assumptions used in the projections to projected capital expenditures, historical data, and results from other areas of the audit. Our audit procedures also included testing the effectiveness of internal controls over the long-lived asset impairment process, including those over the identification of units to be retired from the active fleet and assessed for impairment. ​ /s/ DELOITTE & TOUCHE LLP Houston, Texas February 25, 2025 We have served as the Company’s auditor since 2007 ​ ​ F-2 Table of Contents Archrock, Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS ​ 1. Description of Business 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. 2. Basis of Presentation and Significant Accounting Policies Basis of Presentation Our Financial Statements include the accounts of Archrock and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Our Financial Statements are prepared in accordance with GAAP and the rules and regulations of the SEC. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets and liabilities. Because of the inherent uncertainties in this process, actual future results could differ from those expected as of the reporting date. Management believes that the estimates and assumptions used are reasonable. Except as otherwise noted, any capitalized term used but not defined in our Financial Statements shall have the same meaning provided in our 2024 Form 10-K. Significant Accounting Policies Cash and Cash Equivalents We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Accounts Receivable and Allowance for Credit Losses The contractual life of our trade receivables is primarily 30 days based on the payment terms specified in the contract. Contract operations services are generally billed monthly at the beginning of the month in which service is being provided. Aftermarket services billings typically occur when parts are delivered or service is completed. Due to the short–term nature of our trade accounts receivable, we consider the amortized cost to be the same as the carrying value amount of the receivable, excluding the allowance for credit losses. We recognize an allowance for credit losses when a receivable is recorded, even when the risk of loss is remote. We utilize an aging schedule to determine our allowance for credit losses, and measure expected credit losses on a collective (pool) basis when similar risk characteristics exist. We rely primarily on ratings assigned by external rating agencies and credit monitoring services to assess credit risk and aggregate customers first by low, medium or high-risk asset pools, and then by delinquency status. We also consider the internal risk associated with geographic location and the services we provide to the customer when determining asset pools. If a customer does not share similar risk characteristics with other customers, we evaluate the customer’s outstanding trade receivables for expected credit losses on an individual basis. Each reporting period, we reassess our customers’ risk profiles and determine the appropriate asset pool classification, or perform individual assessments of expected credit losses, based on the customers’ risk characteristics at the reporting date. F-8 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Loss rates are separately determined for each asset pool based on the length of time a trade receivable has been outstanding. We analyze two years of internal historical loss data, including the effects of prepayments, write–offs and subsequent recoveries, to determine our historical loss experience. Our historical loss information is a relevant data point for estimating credit losses, as the data closely aligns with trade receivables due from our customers. Ratings assigned by external rating agencies and credit monitoring services consider past performance and forecasts of future economic conditions in assessing credit risk. Inventory Inventory primarily consists of parts used for maintenance of natural gas compression equipment. Inventory is stated at the lower of cost and net realizable value using the average cost method. Property, Plant and Equipment Property, plant and equipment are recorded at cost and depreciated using the straight–line method over their estimated useful lives as follows: ​ ​ ​ ​ Compression equipment, facilities and other fleet assets 3 to 30 years Buildings ​ 20 to 35 years Transportation and shop equipment ​ 3 to 10 years Computer hardware and software ​ 3 to 5 years Other ​ 3 to 10 years ​ Major improvements that extend the useful life of an asset are capitalized and depreciated over the estimated useful life of the major improvement, up to seven years . Repairs and maintenance are expensed as incurred. Goodwill The goodwill acquired in connection with the TOPS Acquisition represents the excess of consideration transferred over the fair value of the assets and liabilities acquired. We review the carrying amount of our goodwill in the fourth quarter of every year, or whenever indicators of potential impairment exist, to determine if the carrying amount of a reporting unit exceeds its fair value, including the applicable goodwill. We perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is impaired. If the fair value is more-likely-than-not impaired, we perform a quantitative impairment test to identify impairment and measure the amount of impairment loss to be recognized, if any. Our qualitative assessment includes consideration of various events and circumstances and their potential impact to a reporting unit’s fair value, including macroeconomic and industry conditions such as a deterioration in our operating environment and limitations on access to capital and other developments in the equity and credit markets, cost factors that could have a negative effect on earnings and cash flows, relevant entity-specific and reporting unit-specific events and overall financial performance such as declining earnings or cash flows or a sustained decrease in share price. The quantitative impairment test (i) allocates goodwill and our other assets and liabilities to our reporting units, contract operations and aftermarket services, (ii) calculates the fair value of the reporting units and (iii) determines the impairment loss, if any, as the amount by which the carrying amount of the reporting unit exceeds its fair value (limited to the total amount of goodwill allocated to that reporting unit). All of the goodwill recognized in the TOPS Acquisition was attributed to our contract operations reporting unit. F-9 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Leases We determine if an arrangement is a lease, or contains a lease, at inception and record the leases in our consolidated financial statements upon lease commencement, which is the date when the underlying asset is made available for use by the lessor. We recognize ROU assets and operating lease liabilities based on the present value of lease payments over the lease term. As the discount rate implicit in the lease is rarely readily determinable, we estimate our incremental borrowing rate using information available at commencement date in determining the present value of the lease payments. The lease term includes options to extend when we are reasonably certain to exercise the option. Short–term leases, those with an initial term of 12 months or less, are not recorded on the balance sheet. Variable costs such as our proportionate share of actual costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are recognized in the period in which they are incurred. Operating lease expense for lease payments is recognized on a straight–line basis over the term of the lease. Our facility leases, of which we are the lessee, contain lease and nonlease components, which we have elected to account for as a single lease component, as the nonlease components are not significant to the total consideration of the contract and separating the nonlease component would have no effect on lease classification. For contract operations service agreements in which we are a lessor, we do not account for these agreements as operating leases, as the services nonlease component is predominant over the compression package lease component. Impairment of Long–Lived Assets We review long–lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressors from our active fleet, indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows expected from the use of the asset and its eventual disposition are less than its carrying amount. Impairment losses are recognized in the period in which the impairment occurs and represent the excess of the asset carrying value over its fair value. Internal–Use Software Certain of our contracts have been deemed to be hosting arrangements that are service contracts, including those related to the cloud migration of our ERP system and cloud services for our mobile workforce, telematics and inventory management tools. Certain costs incurred for the implementation of a hosting arrangement that is a service contract are capitalized and amortized on a straight–line basis over the term of the respective contract. Amortization begins for each component of the hosting arrangement when the component becomes ready for its intended use. Capitalized implementation costs are presented in other assets, the same line item in our consolidated balance sheets that a prepayment of the fees for the associated hosting arrangement would be presented. Amortization expense of the capitalized implementation costs is presented in SG&A, the same line item in our consolidated statements of operations as the expense for fees for the associated hosting arrangement. Revenue Recognition We recognize revenue when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we are entitled to receive in exchange for those goods or services. Sales and usage–based taxes that are collected from the customer are excluded from revenue. F-10 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Contract Operations Natural Gas Compression Services. Natural gas compression services are generally satisfied over time, as the customer simultaneously receives and consumes the benefits provided by these services. Our performance obligation is a series in which the unit of service is one month, as the customer receives substantially the same benefit each month from the services regardless of the type of service activity performed, which may vary. If the transaction price is based on a fixed fee, revenue is recognized monthly on a straight–line basis over the period that we are providing services to the customer. Amounts invoiced to customers for costs associated with moving our compression assets to a customer site are also included in the transaction price and are amortized over the initial contract term. We do not consider the effects of the time value of money, as the expected time between the transfer of services and payment for such services is less than one year. Variable consideration exists if customers are billed at a lesser standby rate when a unit is not running. We recognize revenue for such variable consideration monthly, as the invoice corresponds directly to the value transferred to the customer based on our performance completed to date. The rate for standby service is lower to reflect the decrease in costs and effort required to provide standby service when a unit is not running. Billable Maintenance Service . We perform billable maintenance service on our natural gas compression equipment at the customer’s request on an as–needed basis. The performance obligation is satisfied, and revenue is recognized at the agreed–upon transaction price at the point in time when service is complete and the customer has accepted the work performed and can obtain the remaining benefits of the service that the unit will provide. Aftermarket Services OTC Parts and Components Sales . For sales of OTC parts and components, the performance obligation is generally satisfied at the point in time when delivery takes place, and the customer obtains control of the part or component. The transaction price is the fixed sales price for the part stated in the contract. Revenue is recognized upon delivery, as we have a present right to payment and the customer has legal title. Maintenance, Overhaul and Reconfiguration Services . For our service activities, the performance obligation is satisfied over time, as the work performed enhances the customer–controlled asset and another entity would not have to substantially re–perform the work we completed if they were to fulfill the remaining performance obligation. The transaction price may be a fixed monthly service fee, a fixed quoted fee or entirely variable, calculated on a time and materials basis. For service provided based on a fixed monthly fee, the performance obligation is a series in which the unit of service is one month. The customer receives substantially the same benefit each month from the service, regardless of the type of service activity performed, which may vary. As the progress towards satisfaction of the performance obligation is measured based on the passage of time, revenue is recognized monthly based on the fixed fee provided for in the contract. For service provided based on a quoted fixed fee, progress towards satisfaction of the performance obligation is measured using an input method based on the actual amount of labor and material costs incurred. The amount of the transaction price recognized as revenue each reporting period is determined by multiplying the transaction price by the ratio of actual costs incurred to date to total estimated costs expected for the service. Significant judgment is involved in the estimation of the progress to completion. Any adjustments to the measure of the progress to completion are accounted for on a prospective basis. Changes to the scope of service are recognized as an adjustment to the transaction price in the period in which the change occurs. Service provided based on time and materials is generally short–term in nature and labor rates and parts pricing is agreed upon prior to commencing the service. We apply an estimated adjusted gross margin percentage, which is fixed based on historical time and materials–based service, to actual costs incurred. We evaluate the estimated adjusted gross margin percentage at the end of each reporting period and adjust the transaction price as appropriate. F-11 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Contract Assets and Liabilities We recognize a contract asset when we have the right to consideration in exchange for goods or services transferred to a customer when the right is conditioned on something other than the passage of time. We recognize a contract liability when we have an obligation to transfer goods or services to a customer for which we have already received consideration. Income Taxes We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rate on deferred tax assets and liabilities is recognized in income in the period of the enactment date. We record net deferred tax assets to the extent we believe these assets will more-likely-than-not be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax–planning strategies and results of recent operations. If a valuation allowance was previously recorded and we subsequently determined we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax assets’ valuation allowance, which would reduce the provision for income taxes. We record uncertain tax positions in accordance with the accounting standard on income taxes under a two–step process whereby (1) we determine whether it is more-likely-than-not that the tax positions will be sustained based on the technical merits of the position and (2) for those tax positions that meet the more–likely–than–not recognition threshold, we recognize the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and trade accounts receivable. Our temporary cash investments have a zero–loss expectation because we maintain minimal balances in our cash investment accounts and have no history of loss. Trade accounts receivable are due from companies of varying size engaged principally in oil and natural gas activities throughout the U.S; therefore, our customers may be similarly affected by changes in economic and other conditions within the industry. We perform periodic evaluations of our customers’ financial condition, including monitoring our customers’ payment history and current credit worthiness to manage this risk. We generally do not obtain collateral for trade accounts receivables, but we may require payment in advance. Payment terms are on a short–term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of the products and services we provide and the terms of our customer agreements. During the year ended December 31, 2024, one customer accounted for $ 121.4 million, or more than 10 % of our consolidated revenue, and another customer accounted for more than 13 % of our consolidated trade accounts receivable, both primarily related to our contract operations segment. ​ F-12 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) 3. Recent Accounting Developments Accounting Standards Updates Implemented Segment Reporting In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosures of significant expenses for each reportable segment, as well as certain other disclosures to help investors understand how the CODM evaluates segment expenses and operating results. ASU 2023-07 allows disclosure of multiple measures of segment profitability if those measures are used to allocate resources and assess performance. We adopted ASU 2023-07 retrospectively during the year ended December 31, 2024. See Note 30 (“Segments”) for further details. 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 assessing and modifying our systems and processes to comply with our future adoption of ASU 2023-09. ​ 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. Disaggregation of Income Statement Expenses ​ In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40), which will require tabular disclosures about certain expenses included in the expense captions presented on the face of the income statement, as well as disclosures about selling expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. Entities are required to adopt ASU 2024-03 prospectively with the option for retrospective application. We are currently evaluating the potential impact of adopting this new guidance on our consolidated financial statements and related disclosures. ​ F-13 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) 4. Business Transactions TOPS Acquisition On August 30, 2024, we completed the TOPS Acquisition, whereby we acquired all of the issued and outstanding equity interests in TOPS, including a fleet of approximately 580,000 horsepower, including approximately 530,000 operating horsepower, for aggregate consideration consisting of $ 868.7 million in cash and approximately 6.9 million shares of common stock with an acquisition date fair value of $ 139.1 million. The cash portion of the purchase price was funded with proceeds from the July 2024 Equity Offering, the 2032 Notes offering and borrowings under the Credit Facility. In accordance with the terms of the purchase and sale agreement, customary post-closing adjustments were made during the fourth quarter of 2024, resulting in a $ 0.4 million reduction to the purchase price . The TOPS Acquisition was accounted for using the acquisition method of accounting, which requires, among other things, assets acquired and liabilities assumed to be recorded at their fair value on the acquisition date. The excess of the consideration transferred over those fair values was recorded as goodwill. The following table summarizes the purchase price allocation based on the fair values of the assets acquired and liabilities assumed as of the acquisition date: ​ ​ ​ ​ (in thousands) ​ ​ Cash $ 2,498 Accounts receivable ​ ​ 9,737 Inventory ​ ​ 7,346 Other current assets ​ ​ 495 Property, plant and equipment ​ ​ 912,877 Operating lease right-of-use assets ​ ​ 1,424 Goodwill ​ ​ 52,155 Intangible assets ​ ​ 76,228 Other assets ​ ​ 4,032 Accounts payable, trade ​ ​ ( 48,946 ) Accrued liabilities ​ ​ ( 4,667 ) Operating lease liabilities ​ ​ ( 1,424 ) Other liabilities ​ ​ ( 4,032 ) Purchase price ​ $ 1,007,723 ​ The valuation methodologies and significant inputs for fair value measurements are detailed by significant asset class below. The fair value measurements for property, plant and equipment and intangible assets are based on significant inputs that are not observable in the market and therefore represent Level 3 measurements. ​ Property, Plant and Equipment ​ Property, plant and equipment is primarily comprised of electric motor drive compression equipment that will depreciate on a straight-line basis over an estimated average remaining useful life of 25 years . The fair value of the property, plant and equipment was determined using both the cost and market approach. For most of the compression equipment, we estimated the replacement cost using the direct cost method by evaluating recent purchases of similar assets or published data, then adjusting the replacement cost for physical deterioration and functional and economic obsolescence, as applicable. For certain compression equipment, we then considered the market approach by comparing our estimated dollar per horsepower to market comparables and market participant assumptions and adjusted as necessary. ​ Other fixed assets were valued using the indirect cost method, whereby we applied asset-specific trend information using published indexes to calculate the estimated replacement cost of assets that were identified to be reflected at historical cost. Other assets were depreciated based on published normal useful life estimates and prior experience with similar assets. F-14 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Intangible Assets ​ The intangible assets consist of customer relationships and trade names that have estimated useful lives of 12 years and five years , respectively. The amount of intangible assets and their associated useful life were determined based on the period over which the assets are expected to contribute directly or indirectly to our future cash flows. ​ The fair value of the identifiable intangible assets related to customer relationships was determined using the multi-period excess earnings method, which is a specific application of the discounted cash flow method, an income approach, whereby we estimated and then discounted the future cash flows of the intangible asset by adjusting overall business revenue for attrition, obsolescence, cost of sales, operating expenses, taxes and the required returns attributable to other contributory assets acquired. Significant estimates made in arriving at expected future cash flows included our expected customer attrition rate and the amount of earnings attributable to the assets. To discount the estimated future cash flows, we utilized a discount rate that was at a premium to our WACC to reflect the less liquid nature of the customer relationships relative to the tangible assets acquired. ​ It is generally accepted that the fair market value of a trade name is best measured by the relief-from-royalty method under the income approach, whereby we calculated the royalty savings by estimating a reasonable royalty rate that a third party would negotiate in a licensing agreement expressed as a percentage of total revenue involving a trade name. The revenue related to the trade name was multiplied by the selected royalty rate over the estimated expected useful life of the trade name to arrive at the royalty savings. The royalty savings were tax effected and discounted to present value using a discount rate commensurate with the risk profile of the trade name relative to our WACC and the return on the other acquired assets. ​ Goodwill ​ The amount of goodwill resulting from the TOPS Acquisition is attributable to the expansion of our services in the Permian Basin, where we currently operate, and was allocated to our contract operations segment. The goodwill recorded is considered to have an indefinite life and will be reviewed annually for impairment or more frequently if indicators of potential impairment exist. All of the goodwill recorded for the TOPS Acquisition is expected to be deductible for U.S. federal income tax purposes. ​ Tax Contingency and Indemnification Asset We recorded a non-income tax based contingency of $ 4.3 million and a corresponding indemnification asset of $ 4.3 million based on facts existing on the acquisition date. The tax contingency arose from pre-acquisition activities of TOPS. As part of the acquisition, the sellers agreed to indemnify us for certain tax contingencies up to $ 21.6 million as of the acquisition date. Dependent upon facts and circumstances, the sellers’ indemnification obligation may be reduced over a period of five years from the acquisition date but may also be extended until the resolution of claims timely submitted to the sellers. Results of Operations The results of operations attributable to the TOPS Acquisition have been included in our consolidated financial statements as part of our contract operations segment since the acquisition date. Revenue attributable to the assets acquired from the acquisition date through December 31, 2024 was $ 65.5 million. We are unable to provide earnings attributable to the assets and liabilities acquired since the acquisition date, as we do not prepare full stand-alone earnings reports for those assets and liabilities. ​ Transaction-Related Costs ​ We recorded $ 13.2 million of transaction-related costs in our consolidated statements of operations during the year ended December 31, 2024. F-15 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) The following table presents transaction-related cost incurred by cost type: ​ ​ ​ ​ ​ ​ ​ Year ended (in thousands) ​ December 31, 2024 Professional fees (1) ​ $ 11,387 Compensation-related costs (2) ​ ​ 1,553 Other costs ​ ​ 309 Total transaction-related costs ​ $ 13,249 (1) Professional fees include legal, advisory, consulting and other fees. (2) Compensation-related costs include amounts related to employee retention and other compensation related arrangements associated with the acquisition. Payments are due and payable at various times up to and including the two-year anniversary of the TOPS Acquisition. ​ Unaudited Pro Forma Financial Information ​ The unaudited pro forma financial information for the years ended December 31, 2024 and 2023 was derived by adjusting our historical financial statements in order to give effect to the assets and liabilities acquired in the TOPS Acquisition. The TOPS Acquisition is presented in this unaudited pro forma financial information as though the acquisition occurred as of January 1, 2023, and reflects the following: ​ ● the effects of the employee retention and other compensation-related arrangements associated with the TOPS Acquisition; ​ ● the application of our accounting policies and adjusting the results of TOPS to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant, and equipment, and intangible assets had been applied from January 1, 2023; ​ ● the interest expense resulting from the 2032 Notes, the 2027 Notes Tender Offer, and the First Amendment to the Amended and Restated Credit Agreement; ​ ● the exclusion of $ 11.4 million of nonrecurring financial advisory, legal, audit and other professional fees incurred related to the acquisition and recorded to transaction-related costs in our consolidated statements of operations during the year ended December 31, 2024, respectively. For the year ended December 31, 2023, pro forma earnings were adjusted to reflect these charges; and ​ ● the income tax effects of the adjustments based on the estimated blended statutory tax rate of 23 % . The unaudited pro forma financial information below is presented for informational purposes only and is not necessarily indicative of our results of operations that would have occurred had the transaction been consummated at the beginning of the period presented, nor is it necessarily indicative of future results. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, (in thousands) 2024 2023 Revenue ​ $ 1,266,659 ​ $ 1,099,080 Net income attributable to Archrock stockholders ​ ​ 191,434 ​ ​ 78,554 ​ ​ 5. Dispositions During 2022, we completed sales of certain contract operations customer service agreements and approximately 770 compressors, comprising approximately 172,000 horsepower, used to provide compression services under those agreements, as well as other assets used to support the operations. The sale constituted a business, and accordingly, we allocated customer–related and contract–based intangible assets based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We recognized an aggregate gain of $ 28.1 million. F-16 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) 6.

Leases We have operating leases for office space, temporary housing, storage and shops. Our leases have remaining lease terms of less than one year to approximately eight years and most include options to extend the lease term, at our discretion, for an additional one to ten years . We are not, however, reasonably certain that we will exercise any of the options to extend them and as such, they have not been included in the remaining lease terms.

Contract Costs For our contract operations segment, we capitalize incremental costs to obtain a contract with a customer if we expect to recover those costs. Capitalized contract costs include commissions paid to our sales force to obtain contract operations contracts. We expense commissions paid for sales of service contracts and OTC parts and components within our aftermarket services segment, as the amortization period is less than one year. We had contract costs of $ 4.1 million and $ 2.2 million associated with sales commissions recorded in our consolidated balance sheets as of December 31, 2024 and 2023, respectively. For our contract operations segment, we capitalize costs incurred to fulfill a contract if those costs relate directly to a contract, enhance resources that we will use in satisfying performance obligations and if we expect to recover those costs. Contract costs incurred to fulfill our customer contracts include freight charges to transport compression assets before transferring services to the customer and mobilization activities associated with our contract operations services. Aftermarket services fulfillment costs are recognized based on the percentage–of–completion method applicable to the customer contract and do not typically result in the recognition of a contract asset. We had contract costs of $ 19.8 million and $ 18.9 million associated with freight and mobilization recorded in our consolidated balance sheets as of December 31, 2024 and 2023, respectively. Contract operations obtainment and fulfillment costs are amortized based on the transfer of service to which the assets relate, which is estimated to be 46 months based on average contract term, including anticipated renewals. Annually, we assess whether the 46–month estimate fairly represents the average contract term and adjust as appropriate. Contract costs associated with commissions are amortized to SG&A. Contract costs associated with freight and mobilization are amortized to cost of sales, exclusive of depreciation and amortization. During the years ended December 31, 2024, 2023 and 2022, we amortized $ 2.3 million, $ 1.9 million and $ 1.9 million, respectively, related to sales commissions, and $ 21.5 million, $ 19.4 million and $ 17.3 million, respectively, related to freight and mobilization. 12. Hosting Arrangements We have hosting arrangements that are service contracts for cloud applications including our ERP, mobile workforce, telematics and inventory management tools. Capitalized implementation costs and accumulated amortization related to our hosting arrangements that are service contracts are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, (in thousands) ​ 2024 ​ 2023 Hosting arrangements ​ $ 20,002 ​ $ 17,832 Accumulated amortization ​ ( 8,329 ) ​ ( 5,320 ) Hosting arrangements, net ​ $ 11,673 ​ $ 12,512 ​ F-20 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) These costs are included in other assets in our consolidated balance sheets. Amortization expense, which is recorded in SG&A in our consolidated statements of operations, was $ 3.0 million, $ 2.6 million and $ 2.0 million during December 31, 2024, 2023 and 2022, respectively. 13. 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. 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 Investment in ECOTEC 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 years ended December 31, 2024, 2023 and 2022, we recognized unrealized losses of $ 1.5 million, $ 1.0 million and $ 1.9 million, respectively, related to the change in fair value of our investment (see Note 27 (“Fair Value Measurements”)). Changes in the fair value of this investment are recognized in other expense, net in our consolidated statements of operations. During the years ended December 31, 2024 and 2023, we contributed $ 1.3 million and $ 3.1 million, respectively, to maintain our 25 % ownership interest in ECOTEC, which is included in other assets in our consolidated balance sheets. Investment in Ionada In November 2023, we agreed and made initial investment of $ 3.8 million, 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. As of December 31, 2024 and 2023, we had a fully diluted ownership equity interest in Ionada of 12 % and 10 %, respectively. We have elected the fair value measurement alternative to account for this investment (see Note 27 (“Fair Value Measurements”)). On November 19, 2024, subject to the same terms and conditions of our initial investment, we invested an additional $ 1.2 million and as a result, the carrying value of our investment in Ionada at December 31, 2024 was $ 5.5 million, including cumulative transaction costs of $ 0.5 million, and is included in other assets in our consolidated balance sheets. There were no upward adjustments, impairments or downward adjustments to the carrying value of the investment as of December 31, 2024. Subject to certain contractual conditions, we may invest on the same terms and conditions as the initial and secondary investments, $ 1.3 million in November 2025 and $ 4.8 million prior to July 2026, for a fully diluted ownership interest of 15 % and 24 %, respectively. ​ F-21 Table of Contents Archrock, Inc.

Notes to Consolidated Financial Statements (continued) Credit Facility First Amendment to the Amended and Restated Credit Agreement On August 28, 2024, we amended our Amended and Restated Credit Agreement to, among other things: ● increase the borrowing capacity of the Credit Facility from $ 750.0 million to $ 1.1 billion; ● increase the portion of the Credit Facility available for the issuance of swing line loans from $ 75.0 million to $ 110.0 million; ● increase the cash dominion trigger threshold amount from $ 75.0 million to $ 110.0 million; ● add certain financial institutions as lenders under the Credit Facility; ● join a newly formed wholly owned subsidiary of Archrock Services, L.P. as a guarantor and grantor under the Credit Facility; and ● modify certain other covenants to which we are subject. We incurred $ 2.6 million in transaction costs related to the First Amendment to the Amended and Restated Credit Agreement, which were included in other assets in our consolidated balance sheets and are being amortized over the remaining term of the Credit Facility. ​ 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 the 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. We incurred $ 6.0 million in transaction costs related to the Amended and Restated Credit Agreement, which were included in other assets in our consolidated balance sheets and are being amortized over the remaining term of the Credit Facility. In addition, we wrote off $ 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 consolidated statements of operations during the year ended December 31, 2023. As of December 31, 2024, there were $ 4.0 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings was 2.2 %. The weighted average annual interest rate on the outstanding balance under our Credit Facility was 6.8 % and 7.7 % at December 31, 2024 and 2023, respectively. As of December 31, 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 December 31, 2024. ​ F-23 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Other Facility Terms ​ As of December 31, 2024, our Credit Facility had an aggregate borrowing commitment of $ 1.1 billion. Subject to certain conditions, including approval by the lenders, we are able to increase the aggregate commitments under the Credit Facility by up to an additional $ 750.0 million. Portions of the Credit Facility, up to $ 110.0 million, are available for the issuance of swing line loans and $ 50.0 million is available for the issuance of letters of credit. The Credit Facility bears interest at either a base rate or SOFR, at our option, plus an applicable margin. The base rate is the highest of (i) the Prime Rate, (ii) the Federal Funds Effective Rate plus 0.50 % and (iii) one-month SOFR plus 1.00 %. Depending on our leverage ratio, the applicable margin varies (i) in the case of base rate loans, from 1.00 % to 1.75 % and (ii) in the case of SOFR loans, from 2.00 % to 2.75 %. Additionally, we are required to pay commitment fees based on the daily unused amount of the Credit Facility at a rate of 0.25 % to 0.375 % depending on the ratio of the outstanding balance to the aggregate borrowing commitment. We incurred $ 2.1 million, $ 1.7 million and $ 1.9 million in commitment fees during the years ended December 31, 2024, 2023 and 2022, respectively. The Credit Facility borrowing base consists of eligible accounts receivable, inventory and compressors, the largest of which is compressors. Borrowings under the Credit Facility are secured by substantially all of our personal property assets and certain of our subsidiaries. The Amended and Restated Credit Agreement contains various covenants including, but not limited to, restrictions on the use of proceeds from borrowings and limitations on our ability to incur additional indebtedness, engage in transactions with affiliates, merge or consolidate, sell assets, make certain investments and acquisitions, make loans, grant liens, repurchase equity and pay distributions. The Amended and Restated Credit Agreement also contains various covenants requiring mandatory prepayments from the net cash proceeds of certain asset transfers. As of December 31, 2024, the following consolidated financial ratios, as defined in our Amended and Restated Credit Agreement, were required: ​ ​ ​ ​ EBITDA to Interest Expense ​ 2.5 to 1.0 Senior Secured Debt to EBITDA ​ 3.0 to 1.0 Total Debt to EBITDA (1) ​ 5.25 to 1.0 (1) Subject to a temporary increase to 5.50 to 1.0 for any quarter during which an acquisition satisfying certain thresholds is completed and for the two quarters immediately following such quarter. 2032 Notes ​ On August 26, 2024, we completed a private offering of $ 700.0 million aggregate principal amount of 6.625 % senior notes due September 2032 and received net proceeds of $ 690.0 million after deducting issuance costs. The $ 10.0 million of issuance costs were recorded as deferred financing costs within long-term debt in our consolidated balance sheets and are being amortized to interest expense in our consolidated statement of operations over the term of the notes. A portion of the net proceeds were used to fund a portion of the cash consideration for the TOPS Acquisition, the 2027 Notes Tender Offer and to repay borrowings outstanding under our Credit Facility. The 2032 Notes have not been and will not be registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the U.S. except pursuant to a registration exemption under the Securities Act and applicable state securities laws. We offered and issued the 2032 Notes only to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to certain non-U.S. persons outside the U.S. in accordance with Regulation S under the Securities Act. F-24 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) The 2032 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by us, and by all of our existing subsidiaries, other than Archrock Partners Finance Corp., which is the issuer of the 2032 Notes. The 2032 Notes and the guarantees rank equally in right of payment with all of our and the guarantors’ existing and future senior unsecured indebtedness. We may, at our option, redeem all of part of the 2032 Notes at any time on or after September 1, 2027, at specified redemption prices, plus any accrued and unpaid interest. In addition, prior to September 1, 2027, we may redeem up to 40 % of the 2032 Notes, in an amount equal to the net cash proceeds of one or more equity offerings, at a specified redemption price, plus any accrued and unpaid interest. We may also redeem all or part of the 2032 Notes at any time prior to September 1, 2027 at a redemption price equal to the principal amount and a make whole premium, plus any accrued and unpaid interest. ​ 2027 Notes Tender Offer In connection with the offering of the 2032 Notes, we completed a concurrent cash tender offer of $ 202.0 million, which reflects approximately 101 % of the aggregate principal amount of the tendered 2027 Notes and $ 0.2 million of agent and legal fees. On the date of tender, the net carrying value of the tendered 2027 Notes was $ 198.8 million and we recorded a debt extinguishment loss of $ 3.2 million in our consolidated statements of operations during the year ended December 31, 2024. 2027 Notes and 2028 Notes In December 2020, we completed a private offering of $ 300.0 million aggregate principal amount of 6.25 % senior notes due April 2028, which were issued pursuant to the indenture under which we completed a private offering of $ 500.0 million aggregate principal amount of 6.25 % senior notes in December 2019. The notes of the two offerings have identical terms and are treated as a single class of securities. The $ 300.0 million of notes were issued at 104.875 % of their face value and have an effective interest rate of 5.6 %. The $ 500.0 million of notes were issued at 100 % of their face value and have an effective interest rate of 6.8 %. We received net proceeds of $ 309.9 million, after deducting issuance costs of $ 4.7 million, from our December 2020 offering and net proceeds of $ 491.8 million, after deducting issuance costs of $ 8.2 million, from our December 2019 offering. In March 2019, we completed a private offering of $ 500.0 million aggregate principal amount of 6.875 % senior notes due April 2027 and received net proceeds of $ 491.2 million after deducting issuance costs of $ 8.8 million. The $ 500.0 million of notes were issued at 100 % of their face value and have an effective interest rate of 7.9 %. In August 2024, we completed a cash tender offer to purchase $ 200 million aggregate principal amount of the 2027 Notes, after which $ 300 million aggregate principal amount of the 2027 Notes remained outstanding. The net proceeds from the 2027 Notes and 2028 Notes were used to repay borrowings outstanding under our Credit Facility. Issuance costs related to the 2027 Notes and 2028 Notes are considered deferred financing costs, and together with the issue premium of the December 2020 offering of 2028 Notes, are recorded within long-term debt in our consolidated balance sheets and are being amortized to interest expense in our consolidated statements of operations over the terms of the notes. The 2027 Notes and 2028 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by us and all of our existing subsidiaries, other than Archrock Partners, L.P. and Archrock Partners Finance Corp., which are co–issuers of both offerings, and certain of our future subsidiaries. The 2027 Notes and 2028 Notes and the guarantees rank equally in right of payment with all of our and the guarantors’ existing and future senior unsecured indebtedness. The 2027 Notes and 2028 Notes may be redeemed at any time, in whole or in part, at specified redemption prices and make–whole premiums, plus any accrued and unpaid interest. F-25 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Maturities of Long–Term Debt As of December 31, 2024, the maturities of our long–term debt, excluding interest to be accrued, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ ​ ​ 2025 ​ $ — 2026 ​ — 2027 ​ 298,542 2028 ​ ​ 1,209,443 2029 ​ — Thereafter ​ 690,391 ​ ​ 17. Commitments and Contingencies Insurance Matters Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability and commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance coverage is customary for the industry and adequate for our business; however, losses and liabilities not covered by insurance would increase our costs. Additionally, we are substantially self–insured for workers’ compensation and employee group health claims in view of the relatively high per–incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. We are also self–insured for property damage to our offshore assets. In August 2021, Hurricane Ida made landfall in Louisiana, causing operational disruptions, damage to compressors and a temporary shutdown of facilities in Louisiana that negatively impacted our financial performance in the quarter. As of December 31, 2021, we had an insurance recovery of $ 2.8 million related to the facility and compressor damages, which we received in cash during the three months ended March 31, 2022. In September 2022, we received an additional $ 0.4 million related to business interruption insurance recovery proceeds. Tax Matters We are subject to a number of state and local taxes that are not income–based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of both December 31, 2024 and 2023, we accrued $ 8.6 million and $ 3.9 million, respectively, for the outcomes of non–income–based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We believe the likelihood is remote that the impact of potential unasserted claims from non–income–based tax audits could be material to our consolidated financial position, but it is possible that the resolution of future audits could be material to our consolidated results of operations or cash flows. As of both December 31, 2024 and 2023, $ 0.6 million of the tax contingencies mentioned above related to audits that have advanced from the audit review phase to the contested hearing phase. As of December 31, 2024, $ 4.3 million of the tax contingencies mentioned above had an offsetting indemnification asset. None were indemnified as of December 31, 2023. F-26 Table of Contents Archrock, Inc. Notes to 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. 18. Stockholders’ Equity July 2024 Equity Offering On July 24, 2024, Archrock sold, pursuant to a public underwriting offering, approximately 12.7 million shares of common stock, including approximately 1.7 million shares of common stock pursuant to an over-allotment option. Archrock received net proceeds of $ 255.7 million, after deducting underwriting discounts, commissions and offering expenses. Proceeds from this equity offering were used to fund a portion of the TOPS Acquisition. TOPS Acquisition On August 30, 2024, we completed the TOPS Acquisition and issued approximately 6.9 million shares of common stock to the sellers as part of the acquisition purchase price. The acquisition date fair value was $ 139.1 million and is reflected in common stock and additional paid-in capital in our consolidated statements of equity. See Note 4 (“Business Transactions”) for further details. 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. 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 at that time. Through December 31, 2024, we had repurchased 1,483,200 common shares at an average price of $ 14.97 per share for an aggregate of $ 22.2 million. As of December 31, 2024, $ 37.9 million remained available for purchase under the Share Repurchase Program. 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 allows 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.

Offerings of common stock pursuant to the ATM Agreement will terminate upon the earlier of (i) the sale of all shares of common stock subject to the ATM Agreement or (ii) the termination of the ATM Agreement by us or by each of the sales agents. Any sales agent may also terminate the ATM Agreement but only with respect to itself.

Notes to Consolidated Financial Statements (continued) Stock Incentive Plans The 2020 Plan was adopted in April 2020 and provides for the granting of stock options, restricted stock, restricted stock units, stock appreciation rights, performance awards, other stock-based awards and dividend equivalent rights to employees, directors and consultants of Archrock. The 2020 Plan is administered by the Compensation Committee of our Board of Directors. Under the 2020 Plan, the maximum number of shares of common stock available for issuance is 8,500,000 . Each stock-settled award granted under the 2020 Plan reduces the number of shares available for issuance by one share. Cash-settled awards are not counted against the aggregate share limit. Shares subject to awards granted under the 2020 Plan that are subsequently canceled, terminated, settled in cash or forfeited, excluding shares withheld to satisfy tax withholding obligations or to pay the exercise price of an option, are available for future grant under the 2020 Plan. The 2020 Plan allows us to withhold shares upon vesting of restricted stock at the then–current market price to cover taxes required to be withheld on the vesting date. During the years ended December 31, 2024, 2023 and 2022, we withheld 392,177 shares valued at $ 6.6 million, 383,128 shares valued at $ 3.8 million and 283,024 shares valued at $ 2.4 million, respectively, to cover tax withholding. On February 19, 2025, the Compensation Committee approved an amendment to the 2020 Plan that provides for the delegation to a subcommittee, which may be comprised of one or more officers of the Company, the authority to grant awards to employees who are not subject to Section 16 of the Exchange Act, subject to certain award size and other limitations. Restricted Stock Awards and Performance–Based Restricted Stock Units Grants of restricted stock are subject to forfeiture, restrictions on transfer and certain other conditions until vesting, which generally occurs in three equal installments following the date of grant. Compensation expense is recognized over the vesting period equal to the fair value of our common stock at the grant date. Our restricted stock includes rights to receive dividends or dividend equivalents. Grants of performance–based restricted stock units are three –year equity settled awards linked to the performance of our common stock. The awards also include dividend equivalent rights that accumulate during the vesting period. We have performance–based restricted stock units whose vesting is dependent on the satisfaction of a combination of certain service–related conditions and our total shareholder return ranked against that of a predetermined peer group over a three –year performance period, as well as performance–based restricted stock units whose vesting is contingent on meeting various horsepower utilization targets over a three –year performance period. The awards vest in their entirety on the date specified in the award agreement following the conclusion of the performance period. The final number of shares of common stock issuable upon vesting can range from 0 % to 250 % of the initial grant depending on the level of achievement as determined by the Compensation Committee of our Board of Directors. The fair value of the horsepower utilization performance-based restricted stock units is equal to the fair value of our common stock at the grant date. The fair value of the total shareholder return performance–based restricted stock units, incorporating the market condition, is estimated on the grant date using a Monte Carlo simulation model. Expected volatilities for us and each peer company utilized in the model are estimated using a historical period consistent with the awards’ remaining performance period as of the grant date. The risk–free interest rate is based on the yield on U.S. Treasury Separate Trading of Registered Interest and Principal Securities for a term consistent with the remaining performance period. The dividend yield used is 0.0 % to approximate accumulation of earnings. F-31 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) The assumptions that were used to estimate the fair value of our restricted stock units and performance–based stock units are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ ​ 2024 ​ 2023 ​ 2022 ​ Remaining performance period as of grant date (in years) ​ 2.9 ​ 2.9 ​ 2.9 Risk-free interest rate used ​ 4.1 % ​ 3.9 % ​ 1.4 % Grant-date fair value ​ $ 23.67 ​ $ 15.68 ​ $ 11.96 ​ ​ Activity related to our restricted stock and performance–based restricted stock units is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ ​ ​ Grant Date ​ ​ ​ ​ Fair Value (in thousands, except per share amounts) Shares Per Share Non-vested restricted stock and performance-based restricted stock units, December 31, 2023 2,625 ​ $ 10.19 Granted 864 ​ 17.44 Adjustment for performance ​ 13 ​ ​ 14.30 Vested ( 1,188 ) ​ 10.22 Canceled ( 38 ) ​ 12.08 Non-vested restricted stock and performance-based restricted stock units, December 31, 2024 2,276 ​ $ 12.81 ​ The grant date fair value of the restricted stock and performance–based restricted stock units granted during the years ended December 31, 2024, 2023 and 2022 was $ 15.1 million, $ 15.3 million and $ 14.3 million, respectively. The fair value of the restricted stock and performance–based restricted stock units vested during the years ended December 31, 2024, 2023 and 2022 was $ 20.2 million, $ 12.4 million and $ 9.3 million, respectively. As of December 31, 2024, we expect $ 14.5 million of unrecognized compensation cost related to our non–vested restricted stock and performance–based restricted stock units to be recognized over the weighted–average period of 1.7 years. Cash Settled Performance Units Grants of cash–settled performance units vest at the end of the three-year vesting period and are payable in an amount of cash equivalent to the value of our common stock at the vesting date for each unit vested. These awards are subject to one or more performance conditions and are accounted for as liability awards with expense based on the fair value measured at the end of each reporting period. These awards also include dividend equivalent rights that accumulate during the vesting period. At the end of each reporting period, the Compensation Committee of our Board of Directors approves the determination of achievement for each performance measure, which can range from 0 % to 200 %.

The performance criteria for the cash settled performance units granted during the year ended December 31, 2020, were not met over the performance period; therefore, the Compensation Committee of our Board of Directors determined that no payout was earned, and no cash was paid upon vesting during the year ended December 31, 2023. Cash paid upon vesting of the cash settled performance units during the years ended December 31, 2024 and 2022 was $ 4.3 million and $ 1.2 million, respectively. As of December 31, 2024, we expect $ 8.4 million of unrecognized compensation cost related to our non–vested liability awards to be recognized over the weighted–average period of 1.5 years. Time-Based Cash or Equity Settled Performance Units In 2024, we issued time-based equity awards that vest in three equal installments following the grant date. These awards are payable in either cash or restricted stock units, at the employees’ option, based on the value of the Company’s common stock at the vesting date. These awards are subject to certain qualifying retirement provisions, are classified as liability awards and expense recognized based on the fair value measured at the end of each reporting period. These awards also include dividend equivalent rights that accumulate during the vesting period. ​ During the year ended December 31, 2024, 187,500 restricted stock units were granted, with a total grant date fair value of $ 3.0 million, none of which vested during the year. As of December 31, 2024, we expect $ 1.8 million of unrecognized compensation cost related to non-vested restricted stock units over a weighted-average period of 1.5 years. ​ Employee Stock Purchase Plan Our ESPP provides employees with an opportunity to participate in our long–term performance and success through the purchase of shares of common stock at a price that may be less than fair market value. Each quarter, eligible employees may elect to withhold a portion of their salary up to the lesser of $ 25,000 per year or 10 % of their eligible pay at a price equal to 85 % to 100 % of the fair market value of the stock as defined by the plan. For the year ended December 31, 2023 and for prior years, the purchase discount under the ESPP was 5 % of the fair market value of our common stock on the first or last trading day of the quarter, whichever is lower. Effective on January 1, 2024, the purchase discount under the ESPP increased to 10 % of the fair market value of our common stock on the first or last trading day or the quarter, whichever is lower. Our ESPP is compensatory and, as a result, we record an expense in our consolidated statements of operations related to the ESPP. The ESPP will terminate on the date that all shares of common stock authorized for sale under the ESPP have been purchased, unless it is extended. The maximum number of shares of common stock available for purchase under the ESPP is 1.0 million. As of December 31, 2024, 281,067 shares remained available for purchase under the ESPP. F-33 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Directors’ Stock and Deferral Plan Our DSDP provides non–employee members of the Board of Directors with an opportunity to elect to receive our common stock as payment for a portion or all of their retainer. The number of shares paid each quarter is determined by dividing the dollar amount of fees elected to be paid in common stock by the closing sales price per share of the common stock on the last day of the quarter. In addition, directors who elect to receive a portion or all of their fees in the form of common stock may also elect to defer, until a later date, the receipt of a portion or all of their fees to be received in common stock. In this case, we issue restricted stock units and the rights to receive dividends or dividend equivalents is accrued and paid when the shares are issued. There are 100,000 shares reserved under the DSDP and, as of December 31, 2024, 37,771 shares remained available to be issued under the plan. 21. Retirement Benefit Plan Our 401(k) retirement plan provides for optional employee contributions up to the applicable IRS annual limit and discretionary employer matching contributions. We make discretionary matching contributions to each participant’s account at a rate of 100 % of each participant’s contributions up to 6 % of eligible compensation as of July 2024. Prior to July 2024, we made discretionary matching contributions to each participant’s account at a rate of 100 % of each participant’s contributions up to 5 % of eligible compensation. We recorded matching contributions of $ 5.9 million, $ 5.2 million and $ 4.9 million during the years ended December 31, 2024, 2023 and 2022, respectively. 22. Long–Lived and Other Asset Impairment Compression Fleet We periodically review the future deployment of our idle compression assets for units that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. Based on these reviews, we determine that certain idle compressors should be retired from the active fleet. The retirement of these units from the active fleet triggers a review of these assets for impairment and as a result of our review, we may record an asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit is estimated based on the expected net sale proceeds compared to other fleet units we recently sold, a review of other units recently offered for sale by third parties or the estimated component value of the equipment we plan to use. In connection with our review of our idle compression assets, we evaluate for impairment idle units that were culled from our fleet in prior years and are available for sale. Based on that review, we may reduce the expected proceeds from disposition and record additional impairment to reduce the book value of each unit to its estimated fair value. The following table presents the results of our compression fleet impairment review as recorded to our contract operations segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, (dollars in thousands) ​ 2024 2023 2022 Idle compressors retired from the active fleet ​ ​ 95 ​ 105 ​ 145 Horsepower of idle compressors retired from the active fleet ​ 66,000 ​ 53,000 ​ 100,000 Impairment recorded on idle compressors retired from the active fleet ​ $ 10,681 ​ $ 12,034 ​ $ 21,431 ​ ​ F-34 Table of Contents Archrock, Inc.

During the years ended December 31, 2024, 2023 and 2022, we paid income taxes, net of $2.2 million, $1.3 million and $0.4 million, respectively. F-35 Table of Contents Archrock, Inc.

Deferred income tax balances are the direct effect of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the taxes are actually paid or recovered.

(2) The 2024 and 2023 net deferred tax asset or liability are reflected in our consolidated balance sheets as deferred tax assets of $ 3.0 million and $ 3.2 million, respectively, and deferred tax liabilities of $ 62.5 million and $ 4.9 million, respectively. Both the 2024 and 2023 balances are based on a U.S. federal tax rate of 21 %. F-36 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Tax Attributes and Valuation Allowances Changes in our valuation allowance are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, (in thousands) ​ 2024 2023 2022 Balance at beginning of period $ ( 1,177 ) $ ( 607 ) $ ( 735 ) Additions to valuation allowance ​ ​ ( 455 ) ​ ​ ( 742 ) ​ ​ ( 88 ) Reductions to valuation allowance ​ ​ 170 ​ ​ 172 ​ ​ 216 Balance at end of period ​ $ ( 1,462 ) ​ $ ( 1,177 ) ​ $ ( 607 ) ​ Pursuant to Sections 382 and 383 of the Code, utilization of loss and credit carryforwards are subject to annual limitations due to any ownership changes of 5% stockholders. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more than 50% over a rolling three–year period. We do not currently expect that any loss carryforwards or credit carryforwards will expire as a result of any 382 or 383 limitations. Our ability to utilize loss carryforwards and credit carryforwards against future U.S. federal taxable income and future U.S. federal income tax may be limited in the future if we have a 50% or more ownership change in our 5% stockholders. We record valuation allowances when it is more-likely-than-not that some portion or all of our deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character and in the appropriate taxing jurisdictions in the future. If we do not meet our expectations with respect to taxable income, we may not realize the full benefit from our deferred tax assets, which would require us to record a valuation allowance in our tax provision in future years. As of each reporting date, we consider new evidence to evaluate the realizability of our net deferred tax asset position by assessing the available positive and negative evidence. Changes to the valuation allowance are reflected in the statement of operations. The amount of our deferred tax assets considered realizable could be adjusted if projections of future taxable income are reduced or objective negative evidence in the form of a three–year cumulative loss is present or both. Should we no longer have a level of sustained profitability, excluding nonrecurring charges, we will have to rely more on our future projections of taxable income to determine if we have an adequate source of taxable income for the realization of our deferred tax assets, namely NOL, interest expense limitation, and tax credit carryforwards. This may result in the need to record a valuation allowance against all or a portion of our deferred tax assets. As of December 31, 2024, we recorded a valuation allowance of $ 0.9 million on our deferred tax asset associated with our ECOTEC investment. At December 31, 2024, we had U.S. federal and state NOL carryforwards of $ 632.3 million and $ 261.5 million, respectively, included in our NOL deferred tax asset that are available to offset future taxable income. If not used, the federal and state NOL carryforwards will begin to expire in 2037 and 2026, respectively, though $ 629.4 million of the U.S. federal and $ 162.9 million of the state NOL carryforwards have no expiration date. In connection with the state NOL deferred tax asset, we recorded a valuation allowance of $ 0.5 million as of both December 31, 2024 and 2023. At December 31, 2024, we had a U.S. federal tax credit carryforward of $ 3.0 million. If not used, the federal tax credit carryforward will begin to expire in 2037. As of December 31, 2024, we had U.S. federal and state interest expense limitation carryforwards of $ 185.8 million and $ 59.4 million, respectively, included in our interest expense limitation deferred tax asset that are available to offset future taxable income. These carryforwards have no expiration. F-37 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Unrecognized Tax Benefits Changes in our unrecognized tax benefits (including discontinued operations) are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, (in thousands) ​ 2024 2023 2022 Beginning balance $ 19,465 $ 19,651 $ 19,594 Additions based on tax positions related to current year ​ 2,402 ​ 1,886 ​ 2,151 Additions based on tax positions related to prior years ​ — ​ — ​ 6 Reductions based on tax positions related to prior years ​ ( 18 ) ​ ( 7 ) ​ ( 105 ) Reductions based on lapse of statute of limitations ​ ( 2,382 ) ​ ( 2,065 ) ​ ( 1,995 ) Ending balance ​ $ 19,467 ​ $ 19,465 ​ $ 19,651 ​ We had $ 19.5 million, $ 19.5 million and $ 19.7 million of unrecognized tax benefits at December 31, 2024, 2023 and 2022, respectively, of which $( 0.6 ) million, $ 1.1 million and $ 1.1 million, respectively, would affect the effective tax rate if recognized and $ 7.9 million, $ 7.9 million and $ 7.9 million, respectively, would be reflected in income from discontinued operations, net of tax if recognized. We recorded $ 2.7 million, $ 2.5 million and $ 2.1 million of potential interest expense and penalties related to unrecognized tax benefits associated with uncertain tax positions (including discontinued operations) in our consolidated balance sheets as of year ended December 31, 2024, 2023 and 2022, respectively. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as reductions in income tax expense. We recorded $ 0.3 million of potential expenses or releases of interest or penalties in our consolidated statements of operations during 2024, $ 0.3 million of potential expenses or releases of interest or penalties during 2023, and no potential interest expense and penalties during 2022. Subject to the provisions of our tax matters agreement with Exterran Corporation, both parties agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin–off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing. As of December 31, 2024 and 2023, we recorded an indemnification asset (including penalties and interest) of $ 7.9 million and $ 7.9 million, respectively, which is related to unrecognized tax benefits in our consolidated balance sheets (see Note 28 (“Discontinued Operations”)). We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal and state jurisdictions. U.S. federal and state income tax returns are generally subject to examination for a period of three to five years after filing the returns. The state impact of any U.S. federal audit adjustments and amendments remains subject to examination by various states for up to one year after formal notification to the states. Due to our NOL carryforwards, our U.S. federal and state income tax returns can be examined back to the inception of our NOL carryforwards; therefore, expanding our examination period beyond 20 years. We are not currently involved in federal nor any state income tax audits. As of December 31, 2024, we believe it is reasonably possible that $ 3.6 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to December 31, 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. F-38 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Impact of New Legislation ​ The Organization for Economic Co-operation and Development has proposed a framework to implement a global minimum tax of 15% for companies with global revenues and profits above certain thresholds (referred to as Pillar 2). During 2023, many countries took steps to incorporate Pillar 2 model rule concepts into their domestic laws. While it is uncertain whether the U.S. will enact legislation to adopt Pillar 2, certain countries in which our unconsolidated affiliates operate have adopted legislation. Based on enacted law we have determined that Pillar 2 does not have a material impact on our Financial Statements. 25. 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: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, (in thousands) ​ 2024 2023 2022 Net income ​ $ 172,231 ​ $ 104,998 ​ $ 44,296 Less: Allocation of earnings to participating securities ​ ( 2,279 ) ​ ( 1,878 ) ​ ( 1,429 ) Net income attributable to common stockholders ​ $ 169,952 ​ $ 103,120 ​ $ 42,867 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Less: Allocation of earnings to cash or share settled restricted stock units ​ ​ 1,004 ​ ​ — ​ ​ — Diluted net income attributable to common stockholders ​ $ 170,956 ​ $ 103,120 ​ $ 42,867 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted-average common shares outstanding used in basic earnings per common share ​ ​ 162,037 ​ ​ 154,126 ​ ​ 153,281 Effect of dilutive securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Performance-based restricted stock units ​ ​ 328 ​ ​ 207 ​ ​ 125 ESPP shares ​ ​ 10 ​ ​ 11 ​ ​ 4 Weighted-average common shares outstanding used in diluted earnings per common share ​ ​ 162,375 ​ ​ 154,344 ​ ​ 153,410 ​ ​ ​ ​ F-39 Table of Contents Archrock, Inc.

Derivatives and Hedging Prior to the expiration of our interest rate swaps in March 2022, we used derivative instruments to manage our exposure to fluctuations in the variable interest rate of our Credit Facility. We did not use derivative instruments for trading or other speculative purposes. The effect of our derivative instruments on our consolidated statements of operations is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, (in thousands) ​ 2024 2023 2022 Total amount of interest expense in which the effects of cash flow hedges and undesignated interest rate swaps are recorded ​ $ — ​ $ — ​ $ 101,259 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swaps designated as cash flow hedging instruments: ​ ​ ​ ​ ​ ​ ​ ​ ​ Pre-tax loss recognized in other comprehensive income ​ $ — ​ $ — ​ $ ( 512 ) Pre-tax loss reclassified from accumulated other comprehensive loss into interest expense ​ — ​ — ​ ( 1,758 ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swaps not designated as hedging instruments: ​ ​ ​ ​ ​ ​ ​ ​ ​ Gain recognized in interest expense ​ $ — ​ $ — ​ $ 523 ​ See Note 18 (“Stockholders’ Equity”) for further details on our derivative instruments. 27. Fair Value Measurements The accounting standard for fair value measurements and disclosures establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value into the following three categories: ● Level 1 – quoted unadjusted prices for identical markets in active markets to which we have access at the date of measurement. ● Level 2 – quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model–derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or prices vary substantially over time or among brokered markets makers. ● Level 3 – model–derived valuation in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those that reflect our own assumptions regarding how market participants would price the asset or liability based on the best available information. Assets and Liabilities Measured at Fair Value on a Recurring Basis Investment in ECOTEC ​ As of December 31, 2024, we owned a 25 % equity interest in ECOTEC (see Note 13 (“Investments in Unconsolidated Affiliates”)). We have elected the fair value option to account for this investment. As of December 31, 2024, the fair value of our investment in ECOTEC is $ 14.7 million. F-40 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) 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. This fair value measurement is classified as Level 3 . The significant unobservable inputs are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Significant ​ Year Ended ​ Year Ended ​ ​ Unobservable ​ December 31, 2024 ​ December 31, 2023 ​ ​ Inputs ​ Range ​ Median ​ Range ​ Median Valuation technique: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Discounted cash flow ​ WACC ​ 0.0 % - 17.0 % ​ ​ 12.9 % ​ 0.4 % - 20.0 % ​ ​ 13.5 % Guideline public company ​ Revenue multiple ​ 1.6 x - 7.3 x ​ ​ 4.3 x ​ 1.5 x - 7.2 x ​ ​ 3.8 x ​ The reconciliation of changes in the fair value of our investment in ECOTEC is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, (in thousands) ​ ​ ​ 2024 ​ ​ 2023 Balance at beginning of period ​ $ 14,905 $ 12,803 Purchases of equity interests ​ ​ ​ 1,250 ​ ​ 3,075 Unrealized loss (1) ​ ​ ​ ( 1,484 ) ​ ​ ( 973 ) Balance at end of period ​ ​ $ 14,671 ​ $ 14,905 (1) Included in other expense, net in our consolidated statements of operations. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Investment in Ionada As of December 31, 2024 and 2023, we had a fully diluted ownership equity interest in Ionada of 12 % and 10 %, respectively, (see Note 13 (“Investments in Unconsolidated Affiliates”)). We have elected the fair value measurement alternative to account for this investment. On November 19, 2024, subject to the same terms and conditions of our initial investment of $ 3.8 million, we invested an additional $ 1.2 million dollars and as a result, the carrying value of our investment in Ionada at December 31, 2024 was $ 5.5 million, which includes cumulative transaction costs of $ 0.5 million. There were no upward adjustments, impairments or downward adjustments to the carrying value of the investment as of December 31, 2024. Subject to certain contractual conditions, we may invest on the same terms and conditions as the initial and secondary investments, $ 1.3 million in November 2025 and $ 4.8 million prior to July 2026, for a fully diluted ownership interest of 15 % and 24 %, respectively. Compression Fleet During the years ended December 31, 2024 and 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 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. 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 impaired compression fleet impaired is as follows: ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ 2024 ​ 2023 F-41 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Impaired compression fleet ​ $ 1,048 ​ $ 1,423 ​ The significant unobservable inputs used to develop the above fair value measurements were weighted by the relative fair value of the compression fleet being measured. Additional quantitative information related to our significant unobservable inputs follows: ​ ​ ​ ​ ​ ​ ​ Range Weighted Average (1) Estimated net sale proceeds: ​ ​ ​ ​ As of December 31, 2024 ​ $ 0 - $ 188 per horsepower ​ $ 46 per horsepower As of December 31, 2023 ​ $ 0 - $ 294 per horsepower ​ $ 50 per horsepower (1) Calculated based on an estimated discount for market liquidity of 25 % and 33 % as of December 31, 2024 and 2023, respectively . See Note 22 (“Long-Lived and Other Asset Impairment”) for further details. Other Financial Instruments The carrying amounts of our cash, receivables and payables approximate fair value due to the short–term nature of those instruments. The carrying amount of borrowings outstanding under our Credit Facility approximates fair value due to its variable interest rate. The fair value of these outstanding borrowings is a Level 3 measurement. The fair value of our fixed rate debt is estimated using yields observable in active markets, which are Level 2 inputs, and was as follows: ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ December 31, ​ ​ 2024 ​ 2023 Carrying amount of fixed rate debt (1) ​ $ 1,790,051 ​ $ 1,297,844 Fair value of fixed rate debt ​ 1,796,000 ​ 1,289,000 (1) Carrying amounts are shown net of unamortized debt premium and deferred financing costs. See Note 16 (“Long-Term Debt”). ​ ​ 28. Discontinued Operations In order to effect the Spin-off and govern our relationship with Exterran Corporation after the Spin-off, we entered into several agreements with Exterran Corporation, including a tax matters agreement, which governs the respective rights, responsibilities and obligations of Exterran Corporation and us with respect to certain tax matters. As of both December 31, 2024 and 2023, we had $ 7.9 million of unrecognized tax benefits (including interest and penalties) related to Exterran Corporation operations prior to the Spin-off recorded to liabilities of discontinued operations in our consolidated balance sheets. We had an offsetting indemnification asset of $ 7.9 million related to these unrecognized tax benefits recorded to assets of discontinued operations as of both December 31, 2024 and 2023. Assets and liabilities of discontinued operations are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, (in thousands) ​ 2024 ​ 2023 Other assets ​ $ 7,868 ​ $ 7,868 Deferred tax assets ​ ​ — ​ ​ — Assets of discontinued operations ​ $ 7,868 ​ $ 7,868 ​ ​ ​ ​ ​ ​ ​ Deferred tax liabilities ​ $ 7,868 ​ $ 7,868 F-42 Table of Contents Archrock, Inc. Notes to Consolidated Financial Statements (continued) Liabilities of discontinued operations ​ $ 7,868 ​ $ 7,868 ​ The acquisition of Exterran Corporation by Enerflex, Ltd. in October 2022 had no impact on the Spin–off related agreements discussed above. ​ ​ ​ 29. Related Party Transactions ECOTEC ​ During the year ended December 31, 2024, we made purchases of $ 0.5 million from our unconsolidated affiliate ECOTEC for use in our operations. Hilcorp From August 2019 to present, our Board of Directors has included a member affiliated with our customer Hilcorp or its subsidiaries or affiliates. Revenue from Hilcorp and affiliates was $ 40.7 million, $ 35.4 million and $ 36.2 million during the years ended December 31, 2024, 2023 and 2022, respectively. Accounts receivable, net due from Hilcorp and affiliates was $ 3.6 million and $ 3.8 million as of December 31, 2024 and 2023, respectively (see Note 6 (“Accounts Receivable, net”)). 30. Segments We manage our business segments primarily based on the type of product or service provided. We operate two segments within the U.S.: contract operations and aftermarket services. The contract operations segment provides natural gas compression services to meet specific customer requirements. The aftermarket services segment provides a full range of services to support the compression needs of customers, from parts sales and normal maintenance services to full operation of a customer’s owned assets. The CODM of Archrock is our President & CEO. Our CODM evaluates the performance of our segments and allocates resources primarily based on adjusted gross margin, defined as revenue less cost of sales, exclusive of depreciation and amortization, which are key components of segment operations. Adjusted gross margin is the primary measure used by our CODM to evaluate segment performance because it focuses on the current performance of segment operations and excludes the impact of the prior historical costs of 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. Our CODM considers adjusted gross margin forecast to actual results and period over period financial variances in conjunction with product and customer service metrics and market trends when assessing segment performance and deciding how to allocate resources. 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.
