ITEM 9A. Controls and Procedures Disclosure Controls and Procedures As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures, and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of December 31, 2021 at the reasonable assurance level. Management’s Annual Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting for us. Our internal control system was designed to provide reasonable assurance regarding the preparation and fair presentation of our published financial statements. There are inherent limitations to the effectiveness of any control system, however well designed, including the possibility of human error and the possible circumvention or overriding of controls. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Management must make judgments with respect to the relative cost and expected benefits of any specific control measure. The design of a control system also is based in part upon assumptions and judgments made by management about the likelihood of future events, and there can be no assurance that a control will be effective under all potential future conditions. As a result, even an effective system of internal control over financial reporting can provide no more than reasonable assurance with respect to the fair presentation of financial statements and the processes under which they were prepared. 52 Table of Contents Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment, management used the criteria set forth by the 2013 Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework. Based on this assessment, our management believes that, as of December 31, 2021, our internal control over financial reporting was effective. Grant Thornton LLP, an independent registered public accounting firm that audited our consolidated financial statements included herein, has also audited the effectiveness of our internal control over financial reporting as of December 31, 2021, as stated in their report, which is included herein. 53 Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Board of Directors of USA Compression GP, LLC and Unitholders of USA Compression Partners, LP Opinion on internal control over financial reporting We have audited the internal control over financial reporting of USA Compression Partners, LP (a Delaware limited partnership) and subsidiaries (the “Partnership”) as of December 31, 2021, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated financial statements of the Partnership as of and for the year ended December 31, 2021, and our report dated February 15, 2022 expressed an unqualified opinion on those financial statements. Basis for opinion The Partnership’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 Partnership’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 Partnership 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. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ GRANT THORNTON LLP Houston, Texas February 15, 2022 54 Table of Contents Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ITEM 9B. Other Information None. ITEM 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections Not applicable. 55 Table of Contents PART III ITEM 10. Directors, Executive Officers and Corporate Governance Board of Directors Our general partner, USA Compression GP, LLC (the “General Partner”), manages our operations and activities. The General Partner is wholly owned by Energy Transfer LP (“Energy Transfer”). The General Partner has a board of directors (the “Board”) that manages our business. The Board is not elected by our unitholders and is not subject to re-election on a regular basis in the future. As the sole member of the General Partner, Energy Transfer is entitled under the limited liability company agreement of the General Partner (the “GP LLC Agreement”) to appoint all directors of the General Partner, subject to rights and restrictions contained in other agreements. The GP LLC Agreement provides that the Board shall consist of between two and eleven persons. The Board is comprised of ten members, nine of whom were designated by Energy Transfer and one of whom was designated by EIG Management Company, LLC (“EIG Management”) pursuant to that certain Board Representation Agreement (the “Board Representation Agreement”) among us, the General Partner, Energy Transfer and EIG Veteran Equity Aggregator, L.P. (along with its affiliated funds, “EIG”) entered into on April 2, 2018 (the “Transactions Date”) in connection with our private placement to EIG and FS Energy and Power Fund (“FS Energy”) of Preferred Units and warrants to purchase common units of the Partnership (the “Warrants”). Under the Board Representation Agreement, EIG Management has the right to designate one member of the Board for so long as EIG and FS Energy own, in the aggregate, more than 5% of the Partnership’s outstanding common units (taking into account the common units issuable upon conversion of the Preferred Units and exercise of the Warrants). EIG Management has designated Matthew S. Hartman to serve on the Board. Four members of the Board are independent as defined under the independence standards established by the NYSE and the SEC. Although the NYSE does not require a publicly traded limited partnership like us to have a majority of independent directors on the Board or to establish a compensation committee or a nominating committee, the Board has elected to have a standing compensation committee (the “Compensation Committee”). We do not have a nominating committee in light of the fact that Energy Transfer and EIG currently collectively appoint all of the members of the Board. Eric D. Long, our President and Chief Executive Officer (“CEO”), is currently the only management member of the Board. The non-management members of the Board meet in executive session without any members of management present at least twice a year. Mr. William S. Waldheim presides at such meetings. Interested parties can communicate directly with non-management members of the Board by mail in care of the General Counsel and Secretary at USA Compression Partners, LP, 111 Congress Avenue, Suite 2400, Austin, Texas 78701. Such communications should specify the intended recipient or recipients. Commercial solicitations or similar communications will not be forwarded to the Board. As a limited partnership, NYSE rules do not require us to seek unitholder approval for the election of any of our directors. We do not have a formal process for identifying director nominees, nor do we have a formal policy regarding consideration of diversity in identifying director nominees. We believe, however, that the individuals appointed as directors have experience, skills and qualifications relevant to our business and have a history of service in senior leadership positions with the qualities and attributes required to provide effective oversight of the Partnership. Independent Directors . The Board has determined that Matthew S. Hartman, Glenn E. Joyce, W. Brett Smith and William S. Waldheim are independent directors under the standards established by the NYSE and the Exchange Act. The Board considered all relevant facts and circumstances and applied the independence guidelines of the NYSE and the Exchange Act in determining that none of these directors has any material relationship with us, our management, the General Partner or its affiliates or our subsidiaries. Mr. Hartman is a Managing Director at EIG, and, since the Transactions Date, EIG owns over 80% of the Preferred Units and Warrants in the Partnership. The Board determined that EIG’s ownership of Preferred Units and Warrants did not preclude the independence of Mr. Hartman because (i) the Preferred Units and Warrants do not confer voting rights sufficient to participate in the control of the Partnership or influence its management, (ii) the Board Representation Agreement does not grant to EIG a sufficient number of seats on the Board to significantly influence or control its decision making or materially influence the management or operation of the Partnership and (iii) the Board has determined that ownership of even a significant amount of the Partnership’s securities does not, by itself, preclude a finding of independence. Mr. Smith is President of, and owns limited partnership interests in, Promontory Exploration, LP, Rubicon Oil & Gas II LP and Quientesa Royalty LP, which entities own non-operating working or royalty interests in wells and receive proceeds from liquids production purchased by a subsidiary of Energy Transfer under agreements with well operators. The Board determined that Mr. Smith’s association with these entities did not preclude the independence of Mr. Smith. 56 Table of Contents The Board’s Role in Risk Oversight The Board administers its risk oversight function as a whole and through its committees. It does so in part through discussion and review of our business, financial reporting and corporate governance policies, procedures and practices, with opportunity to make specific inquiries of management. In addition, at each regular meeting of the Board, management provides a report of the Partnership’s operational and financial performance, which often prompts questions and feedback from the Board. The audit committee of the Board (the “Audit Committee”) provides additional risk oversight through its quarterly meetings, where it discusses policies with respect to risk assessment and risk management, reviews contingent liabilities and risks that may be material to the Partnership and assesses major legislative and regulatory developments that could materially impact the Partnership’s contingent liabilities and risks. The Audit Committee is also required to discuss any material violations of our policies brought to its attention on an ad hoc basis. Additionally, the Compensation Committee reviews our overall compensation program and its effectiveness at both linking executive pay to performance and aligning the interests of our executives and our unitholders. Committees of the Board of Directors Audit Committee. The Board appoints the Audit Committee, which is comprised solely of directors who meet the independence and experience standards established by the NYSE and the Exchange Act. The Audit Committee consists of Messrs. Hartman, Joyce, Smith and Waldheim, and Mr. Waldheim serves as chairman of the Audit Committee. The Board determined that Mr. Waldheim is an “audit committee financial expert” as defined in Item 407(d)(5)(ii) of SEC Regulation S-K, and that each of Messrs. Hartman, Joyce, Smith and Waldheim is “independent” within the meaning of the applicable NYSE and Exchange Act rules governing audit committee independence. The Audit Committee assists the Board in its oversight of the integrity of our financial statements and our compliance with legal and regulatory requirements as well as the effectiveness of our corporate policies and internal controls. The Audit Committee has the sole authority to retain and terminate our independent registered public accounting firm, approve all auditing services and related fees and the terms thereof, and pre-approve any non-audit services to be rendered by our independent registered public accounting firm. The Audit Committee is also responsible for confirming the independence and objectivity of our independent registered public accounting firm. Our independent registered public accounting firm is given unrestricted access to the Audit Committee. The charter of the Audit Committee (the “Audit Committee Charter”) is available under the Investor Relations tab on our website at usacompression.com. We will provide a copy of the Audit Committee Charter to any of our unitholders without charge upon written request to Investor Relations, 111 Congress Avenue, Suite 2400, Austin, TX 78701. Compensation Committee. The NYSE does not require a listed limited partnership like us to have a compensation committee. However, the Board established the Compensation Committee to, among other things, oversee our compensation program described below in Part III, Item 11 “Executive Compensation.” The Compensation Committee consists of Messrs. Joyce, Smith and Waldheim and is chaired by Mr. Joyce. The Compensation Committee establishes and reviews general policies related to our compensation and benefits and is responsible for making recommendations to the Board with respect to the compensation and benefits of the Board. In addition, the Compensation Committee administers the USA Compression Partners, LP 2013 Long-Term Incentive Plan, as amended and as may be further amended or replaced from time to time (the “LTIP”). Under the charter of the Compensation Committee (the “Compensation Committee Charter”), a director serving as a member of the Compensation Committee may not be an officer of or employed by the General Partner, us or our subsidiaries. During 2021, none of Mr. Joyce, Mr. Smith or Mr. Waldheim was an officer or employee of Energy Transfer or any of its affiliates, or served as an officer of any company with respect to which any of our executive officers served on such company’s board of directors. In addition, none of Mr. Joyce, Mr. Smith or Mr. Waldheim is a former employee of Energy Transfer or any of its affiliates. The Compensation Committee Charter is available under the Investor Relations tab on our website at usacompression.com. We will provide a copy of the Compensation Committee Charter to any of our unitholders without charge upon written request to Investor Relations, 111 Congress Avenue, Suite 2400, Austin, TX 78701. Conflicts Committee. As set forth in the GP LLC Agreement, the General Partner may, from time to time, establish a conflicts committee to which the Board will appoint independent directors and which may be asked to review specific matters that the Board believes may involve conflicts of interest between us, our limited partners and Energy Transfer. Such conflicts committee will determine the resolution of the conflict of interest in any matter referred to it in good faith. The members of the conflicts committee may not be officers or employees of the General Partner or directors, officers or employees of its affiliates, including Energy Transfer, and must meet the independence and experience standards established by the NYSE and the Exchange Act to serve on the Audit Committee, and certain other requirements. Any matters approved by the conflicts 57 Table of Contents committee in good faith will be conclusively deemed to be fair and reasonable to us, approved by all of our partners and not a breach by the General Partner of any duties it may owe us or our unitholders. Corporate Governance Guidelines and Code of Ethics The Board has adopted Corporate Governance Guidelines (the “Guidelines”) that outline important policies and practices regarding our governance and provide a framework for the function of the Board and its committees. The Board has also adopted a Code of Business Conduct and Ethics (the “Code”) that applies to the General Partner and its subsidiaries and affiliates, including us, and to all of its and their directors, employees and officers, including its principal executive officer, principal financial officer and principal accounting officer. We intend to post any amendments to the Code, or waivers of its provisions applicable to our directors or executive officers, including our principal executive officer and principal financial officer, on our website. The Guidelines and the Code are available under the Investor Relations tab on our website at usacompression.com. We will provide copies of the Guidelines and the Code to any of our unitholders without charge upon written request to Investor Relations, 111 Congress Avenue, Suite 2400, Austin, TX 78701.

To our knowledge and based solely on a review of Section 16(a) forms filed electronically with the SEC, we believe that all reporting obligations of the members of the Board, our executive officers and greater than 10 percent unitholders under Section 16(a) were satisfied during the year ended December 31, 2021. Common Unit Ownership by Directors and Executive Officers We encourage our directors and executive officers to invest in and retain ownership of our common units, but we do not require such individuals to establish and maintain a particular level of ownership. Reimbursement of Expenses of the General Partner The General Partner does not receive any management fee or other compensation for its management of us, but we reimburse the General Partner and its affiliates for all expenses incurred on our behalf, including the compensation of employees of the General Partner or its affiliates that perform services on our behalf. These expenses include all expenditures necessary or appropriate to the conduct of our business and that are allocable to us. The Partnership Agreement provides that the General Partner will determine in good faith the expenses that are allocable to us. There is no cap on the amount that may be paid or reimbursed to the General Partner or its affiliates for compensation or expenses incurred on our behalf. ITEM 11. Executive Compensation As is commonly the case with publicly traded limited partnerships, we have no officers, directors or employees. Under the terms of the Partnership Agreement, we are ultimately managed by the General Partner, which is controlled by Energy Transfer. All of our employees, including our executive officers, are employees of USA Compression Management Services, LLC 61 Table of Contents (“USAC Management”), a wholly owned subsidiary of the General Partner. References to “our officers” and “our directors” refer to the officers and directors of the General Partner. Compensation Discussion & Analysis Named Executive Officers The following disclosure describes the executive compensation program for the named executive officers identified below (the “NEOs”). For the year ended December 31, 2021, the NEOs were: • Eric D. Long, President and CEO; • Matthew C. Liuzzi, Vice President, Chief Financial Officer and Treasurer; • Eric A. Scheller, Vice President and Chief Operating Officer; • Christopher W. Porter, Vice President, General Counsel and Secretary; and • Sean T. Kimble, Vice President, Human Resources. Compensation Philosophy and Objectives Since our initial public offering in 2013, we have consistently based our compensation philosophy and objectives on the premise that a significant portion of each NEO’s total compensation should be incentive-based or “at-risk” compensation. We share Energy Transfer’s philosophy that the NEOs’ total compensation levels should be competitive in the marketplace for executive talent and abilities. The Compensation Committee generally targets a competitive range at or near the 50th percentile of the market for aggregate compensation consisting of the three main components of our compensation program: base salary, annual discretionary cash bonus and long-term equity incentive awards. The Compensation Committee believes that a desirable balance of incentive-based compensation is achieved by: (i) the payment of annual discretionary cash bonuses that consider (a) the achievement of the financial and operational performance objectives for a fiscal year set at the beginning of such fiscal year and (b) the individual contributions of each NEO to our level of success in achieving the annual financial and operational performance objectives, and (ii) the annual grant of time-based restricted phantom unit awards under the LTIP, which awards are intended to incentivize and retain our key employees for the long-term and motivate them to focus their efforts on increasing the market price of our common units and the level of cash distributions we pay to our common unitholders. The following charts illustrate the level of at-risk incentive compensation we awarded in 2021 to our CEO and, on an averaged basis, the other NEOs. “Variable/at-risk” compensation is comprised of long-term equity incentive awards and annual discretionary cash bonuses, and “fixed” compensation is comprised of base salary. Our compensation program is structured to achieve the following: • compensate executive officers with an industry-competitive total compensation package of competitive base salaries and significant incentive opportunities yielding a total compensation package in a competitive range at or near the 50th percentile of the market; • attract, retain and reward talented executive officers and key members of management by providing a total compensation package competitive with those of their counterparts at similarly situated companies; 62 Table of Contents • motivate executive officers and key employees to achieve strong financial and operational performance; • ensure that a significant portion of each executive officer’s compensation is performance-based or “at risk” compensation; and • reward individual performance. Methodology to Setting Compensation Packages Our executive compensation program is administered by the Compensation Committee. The Compensation Committee considers market trends in compensation, including the practices of identified competitors, and the alignment of the compensation program with the Partnership’s compensation philosophy described above. Specifically, for the NEOs, the Compensation Committee: • establishes and approves target compensation levels for each NEO; • approves Partnership performance measures and goals; • determines the mix between cash and equity compensation, short-term and long-term incentives and benefits; • verifies the achievement of previously established performance goals; and • approves the resulting cash or equity awards to the NEOs. The Compensation Committee also considers other factors such as the role, contribution, skills, experience and performance of an individual relative to his or her peers at the Partnership. The Compensation Committee does not assign a specific weight to these factors, but rather makes a subjective judgment taking all of these factors into account. The Compensation Committee reviews and approves all compensation for the NEOs. In determining the compensation for the NEOs, the Compensation Committee takes into account input from the CEO, for the compensation of the other NEOs. The CEO considers comparative compensation data and evaluates the individual performance of each NEO and their respective contributions to the Partnership. The recommendations are then reviewed by the Compensation Committee, which may accept the recommendations or make adjustments to the recommended compensation based on the Compensation Committee’s assessment of the individual’s performance and contributions to the Partnership. The CEO’s compensation is reviewed and approved by the Compensation Committee based on comparative compensation data and the Compensation Committee’s independent evaluation of the CEO’s contributions to the Partnership’s performance. The Compensation Committee regularly compares results for the annual base salary, annual short-term cash bonus and long-term equity incentive awards of the NEOs against data for compensation levels for specific executive positions reported in published executive compensation surveys within each of the (i) energy industry and (ii) overall market. The Compensation Committee also reviews publicly filed peer group executive compensation disclosures pertaining to certain executive roles, but because of limited sample size due to the relatively small number of publicly traded natural gas compression companies, the Compensation Committee uses this data as a reference point rather than a primary data source. Periodically, we engage a third-party consultant to provide the Compensation Committee with market information about compensation levels at peer companies to assist in evaluating compensation levels for our executives, including the NEOs. In 2019, Longnecker & Associates (“Longnecker”), who was also the independent compensation advisor to Energy Transfer in 2019, was engaged to provide an updated targeted market review and benchmarking for certain members of our senior leadership team (the “2019 Longnecker Report”). In 2020, the Compensation Committee determined that the 2019 Longnecker Report was completed recently enough to be utilized as a data source in reviewing and setting 2021 NEO compensation levels. As a result, the Compensation Committee relied on the results of the 2019 Longnecker Report for information on base salary, bonus and general compensation items for 2021 for the NEOs (as discussed below, our Compensation Committee utilized another report in determining the number of equity awards that should be granted to our NEOs in December 2021). 63 Table of Contents For purposes of the 2019 Longnecker Report, our peer group, as selected by the Compensation Committee in consultation with Longnecker, included the following companies: Company Ticker 1. Antero Midstream Corporation AM 2. Archrock, Inc. AROC 3. Crestwood Equity Partners LP CEQP 4. Genesis Energy, L.P. GEL 5. Holly Energy Partners, L.P. HEP 6. Martin Midstream Partners L.P. MMLP 7. NuStar Energy, L.P. NS 8. SemGroup Corporation SEMG 9. Summit Midstream Partners, LP SMLP 10. Tallgrass Energy, LP TGE During 2021, Meridian Compensation Partners, LLC (“Meridian”), the independent compensation advisor to Energy Transfer, was engaged to conduct a new report on market information and compensation levels of our peer companies that provided the Compensation Committee with assistance in setting NEO compensation for the 2022 year (the “2021 Meridian Report”). The Compensation Committee also utilized the 2021 Meridian Report when determining the number of equity awards that should be granted to our NEOs in December 2021, which were based on the then-determined 2022 base salaries of the NEOs. In connection with the engagement of Meridian, based on the information presented to it, the Compensation Committee assessed the independence of Meridian under applicable SEC and NYSE rules and concluded that Meridian’s work for the Compensation Committee did not raise any conflicts of interest. For purposes of the 2021 Meridian Report, our peer group included the following companies: Company Ticker 1. Antero Midstream Corporation AM 2. Archrock, Inc. AROC 3. Crestwood Equity Partners LP CEQP 4. DCP Midstream, LP DCP 5. Enerflex Ltd. ENRFF 6. Enlink Midstream, LLC ENLC 7. Equitrans Midstream Corporation ETRN 8. Exterran Corporation EXTN 9.

TTI 15. Western Midstream Partners, LP WES 64 Table of Contents Elements of the Compensation Program Compensation for the NEOs consists primarily of the following elements and corresponding objectives: Compensation Element Primary Objective Base salary To recognize performance of job responsibilities and to attract and retain individuals with superior talent. Annual incentive compensation To promote near-term performance objectives and reward individual contributions to the achievement of those objectives. Long-term equity incentive awards To emphasize long-term performance objectives, encourage the maximization of unitholder value and retain key executives by providing an opportunity to participate in the ownership of the Partnership. Retirement savings (401(k)) plan To provide an opportunity for tax-efficient savings. Other elements of compensation and perquisites To attract and retain talented executives in a cost-efficient manner by providing benefits comparable to those offered by similarly situated companies. Base Salary for 2021 Base salaries for the NEOs have generally been set at a level deemed appropriate by the Compensation Committee to attract and retain individuals with superior talent. Base salary increases are determined based upon the job responsibilities, demonstrated proficiency and performance of the NEO and market conditions. In connection with determining base salaries for each of the NEOs for 2021, the Compensation Committee and CEO utilized the 2019 Longnecker Report to determine comparable salaries for such executive roles within our peer group, and determined that the NEOs’ base salaries were generally in line with the market, and provided a merit increase for certain NEOs for the 2021 year. The 2021 base salaries and 2020 base salaries for the NEOs, including our CEO, are set forth in the following table: Name and Principal Position 2021 Base Salary ($) 2020 Base Salary ($) Eric D. Long, President and Chief Executive Officer 664,050 664,050 Matthew C. Liuzzi, Vice President, Chief Financial Officer and Treasurer 412,000 412,000 Eric A. Scheller, Vice President and Chief Operating Officer 350,000 331,500 (1) Christopher W. Porter, Vice President, General Counsel and Secretary 330,000 315,000 Sean T. Kimble, Vice President, Human Resources 325,000 316,900 ________________________ (1) The amount above reflects the base salary effective upon Mr. Scheller’s appointment as Vice President and Chief Operating Officer on June 2, 2020. Mr. Scheller’s base salary for 2020 in his prior position was $265,225. See “ – Summary Compensation Table” below for the salary received by Mr. Scheller in 2020. Annual Cash Incentive Compensation for 2021 Each of the NEOs is entitled to participate in the USA Compression Partners, LP Amended and Restated Annual Cash Incentive Plan (the “Bonus Plan”) and their potential bonus is governed by the Bonus Plan and, for Messrs. Porter and Kimble, also governed by their respective employment agreements. The Compensation Committee acts as the administrator of the Bonus Plan under the supervision of the full Board, and has the discretion to amend, modify or terminate the Bonus Plan at any time. In February 2022, the Compensation Committee made the determination to pay annual cash bonus awards to executives, including the NEOs, under the Bonus Plan attributable to the year ended December 31, 2021. Although the Bonus Plan is generally based upon our satisfaction of certain performance measures that were previously established for the 2021 year, the Compensation Committee retains the authority to use its business judgement to make decisions or adjustments to the Bonus Plan’s funding pool or the individual bonus awards resulting from the guidelines set forth below. The Bonus Plan contains four 65 Table of Contents payout factors and corresponding percentages that comprise the total annual target bonus for all eligible employees, including the NEOs (the “Annual Target Bonus Pool”), as shown in the following chart. Bonus Plan Payout Factors Payout Factor % of Total Annual Target Bonus Adjusted EBITDA Budget Target Factor 30% Distributable Cash Flow Budget Target Payout Factor 30% Leverage Ratio Budget Target Factor 30% Safety Budget Target Payout Factor 10% Each of the Adjusted EBITDA Budget Target Factor (the “Adjusted EBITDA Factor”) and the Distributable Cash Flow Budget Target Payout Factor (the “DCF Factor”) assign payout factors from 0% to 120% based on the percentage of the Partnership’s budgeted Adjusted EBITDA and DCF, respectively, achieved for the year, as shown in the following chart. Adjusted EBITDA and DCF Factors % of Budget Target Bonus Pool Payout Factor Greater than or equal to 110% 1.20x 109.9% – 105.0% 1.10x 104.9% – 95.0% 1.00x 94.9% – 90.0% 0.90x 89.9% – 80.0% 0.75x Less than 80.0% 0.00x For the 2021 year, the Compensation Committee set the Adjusted EBITDA Budget Target at $396.0 million and the DCF Budget Target at $203.0 million. The Leverage Ratio Budget Target Factor (the “Leverage Ratio Factor”) assigns payout factors based on the Partnership’s achievement of its budgeted Leverage Ratio (as defined in the Partnership’s Credit Agreement, provided that, for purposes of calculating the Leverage Ratio for the Bonus Plan, EBITDA attributable to the full plan year is used in lieu of any other time period) for the year, as shown in the following chart. Leverage Ratio Factor Range within Budget Target Bonus Pool Payout Factor More than 0.250 below budget target 1.20x 0.250 – 0.125 below 1.10x 0.124 below – 0.125 above 1.00x 0.126 – 0.375 above 0.70x 0.376 – 0.500 above 0.50x Greater than 0.500 above 0.00x For the 2021 year, the Compensation Committee set the Leverage Ratio Budget Target at 5.21x. 66 Table of Contents The Safety Budget Target Payout Factor (the “Safety Factor”) assigns payout factors based on the Partnership’s Total Recordable Incident Rate, or TRIR (as calculated by the U.S. Occupational Safety and Health Administration) against the Partnership’s TRIR target, as shown in the following chart. Safety Factor % of Target Bonus Pool Payout Factor Less than 100% 1.00x 100% – 105% 0.90x 105.1% – 110% 0.80x 110.1% – 115% 0.70x 115.1% – 125% 0.60x Greater than 125% 0.00x For the 2021 year, the Compensation Committee set the Safety Target at 0.80. The establishment and amount of the bonus pool is 100% discretionary and subject to approval and/or adjustment by the Compensation Committee. In determining bonuses for the NEOs, the Compensation Committee takes into account whether the Partnership achieved or exceeded its targeted performance objectives. In the case of the NEOs, their bonus pool targets for the 2021 year range from 90% to 125% of their respective annual base earnings (which amount reflects the actual base salary earned during the calendar year to reflect periods before and after any base salary adjustment). For the 2021 year, the Compensation Committee set a target bonus amount (the “Target Bonus”) for each NEO prior to the first quarter of the 2021 year, which was set as a percentage of the NEO’s base salary. For the bonus applicable to the 2021 year, the Target Bonus, as a percentage of base salary and as a dollar amount, is reflected in the table below. Name Percentage of Base Salary Amount ($) Eric D. Long, President and Chief Executive Officer 125 % 830,063 Matthew C. Liuzzi, Vice President, Chief Financial Officer and Treasurer 105 % 432,600 Eric A. Scheller, Vice President and Chief Operating Officer 90 % 315,000 Christopher W. Porter, Vice President, General Counsel and Secretary 90 % 297,000 Sean T. Kimble, Vice President, Human Resources 90 % 292,500 The annual cash bonus pool targets for 2021 were based on the determination of the Compensation Committee in consultation with Longnecker, and in consideration of the available compensation data and the role, contribution, skills, experience and performance of an individual relative to his or her peers at the Partnership. Target Bonuses, if any, are paid within one week following delivery by our independent auditor of the audit of our financial statements for the year to which the Target Bonus relates, but in any case no later than March 15 of the year following the year to which the Target Bonus relates. For the year ended December 31, 2021, we achieved (i) Adjusted EBITDA of $398,379,812, resulting in an Adjusted EBITDA Bonus Pool Payout Factor of 1.00; (ii) DCF of $209,128,262, resulting in a DCF Bonus Pool Payout Factor of 1.00; (iii) Leverage Ratio, as calculated for the purposes of the Bonus Plan, of 5.07, resulting in a Leverage Ratio Bonus Pool Payout Factor of 1.10; and (iv) a TRIR of 0.75 resulting in a Safety Bonus Pool Payout Factor of 1.0. Based on these payout factors, the awards made pursuant to the Bonus Plan with respect to the year ended December 31, 2021 equal 103% of each NEOs Target Bonus and were as follows: Name Bonus ($) Eric D. Long, President and Chief Executive Officer 854,965 Matthew C. Liuzzi, Vice President, Chief Financial Officer and Treasurer 445,578 Eric A. Scheller, Vice President and Chief Operating Officer 324,450 Christopher W. Porter, Vice President, General Counsel and Secretary 305,910 Sean T. Kimble, Vice President, Human Resources 301,275 Long-Term Equity Incentive Awards The LTIP, which has been in effect since 2013, is designed to promote our interests, as well as the interests of our unitholders, by rewarding our officers, directors and certain of our employees for delivering desired performance results, as 67 Table of Contents well as by strengthening our ability to attract, retain and motivate qualified individuals to serve as officers, directors and employees. The LTIP provides for the grant, from time to time at the discretion of the Compensation Committee, of unit awards, restricted units, phantom units, unit options, unit appreciation rights, DERs and other common unit-based awards, although since our initial public offering in 2013 the Board has only granted awards of phantom units with DERs under the LTIP. The Compensation Committee acts as the administrator of the LTIP. Each phantom unit (“Phantom Unit”) relates to one of our common units, and represents the right to receive (as applicable) a common unit or an amount of cash equal to the fair market value of a common unit (or a combination thereof) upon the vesting of such Phantom Unit pursuant to the LTIP, the applicable award agreement thereunder (“Phantom Unit Agreement”) and as determined by the Compensation Committee in its discretion. The outstanding, unvested Phantom Units granted under the LTIP and held by the NEOs are reflected below in “– Outstanding Equity Awards as of December 31, 2021.” Our current Phantom Unit Agreement (i) provides for incremental vesting over five years in two tranches ((a) 60% on the third December 5 following the grant and (b) 40% on the fifth December 5 following the grant), (ii) provides for vesting of 100% of the outstanding, unvested Phantom Units in the event of (a) a Change in Control (as defined under the LTIP and set forth below under “Potential Payments upon Termination or Change in Control”) or (b) the death or Disability (as defined under the LTIP and set forth below under “Potential Payments upon Termination or Change in Control”) of the NEO, (iii) provides for vesting of 40% of the outstanding, unvested Phantom Units if the NEO voluntarily retires between the ages of 65-68 and has been employed by us, our General Partner, or our or its affiliates for at least 10 years (with the remaining 60% being forfeited), and (iv) provides for vesting of 50% of the outstanding, unvested Phantom Units if the NEO voluntarily retires over the age 68 and has been employed by us, our General Partner, or our or its affiliates for at least 10 years (with the remaining 50% being forfeited). The vesting of the Phantom Units are subject, in each case, to the NEO’s continued employment with us until the relevant vesting date. The target level of annual long-term incentive awards for each of the NEOs is expressed as a percentage of the NEO’s base salary. In determining the level of the December 2021 grants of Phantom Units to the NEOs, the Compensation Committee, taking into account market data contained in the 2021 Meridian Report and the role, contribution, skills, experience and performance of an NEO relative to his or her peers at the Partnership, determined each of the NEOs’ long-term incentive targets. Due to the fact that determinations were made in late 2021, the base salaries used for these calculations were the then-determined base salaries set for the 2022 calendar year. Each NEO’s grant value is shown in the following table: Long-Term Incentive Target Amounts for the Year Ended December 31, 2021 Name Percentage of Base Salary Grant Date Amount ($) Eric D. Long, President and Chief Executive Officer 400 % 2,735,886 Matthew C. Liuzzi, Vice President, Chief Financial Officer and Treasurer 250 % 1,060,900 Eric A. Scheller, Vice President and Chief Operating Officer 200 % 721,000 Christopher W. Porter, Vice President, General Counsel and Secretary 200 % 720,000 Sean T. Kimble, Vice President, Human Resources 175 % 568,750 Under the LTIP, the Compensation Committee has the discretion to determine whether any portion of Phantom Units should be settled in cash upon vesting. On October 28, 2020, the Compensation Committee approved the default settlement method for Phantom Units of 50% in cash (valued based on the closing price on the NYSE of the Partnership’s common units on the date of vesting) and 50% in common units for all vesting of Phantom Units occurring during 2021. However, the Compensation Committee also specified that if an employee affirmatively requests in writing that the percentage of cash settlement be set at a specific amount that is less than 50% (and such employee agrees to pay out of his or her own funds the amount of any required federal withholding to the extent that the cash portion is insufficient for the Partnership to withhold and pay such amounts on the employee’s behalf), the Board approves in advance such lesser cash settlement percentage. Each Phantom Unit granted to an employee, including the NEOs, is granted in tandem with a corresponding DER, which entitles the recipient to receive an amount in cash on a quarterly basis equal to the product of (a) the number of Phantom Units granted to the grantee that remain outstanding and unvested as of the record date for the distribution on the Partnership’s common units for such quarter and (b) the quarterly distribution with respect to the Partnership’s common units. Awards granted pursuant to the LTIP are subject to certain clawback features, and the award may not vest or settle if we determine that the recipient committed certain acts of misconduct, as more particularly described in the LTIP. 68 Table of Contents Retention Phantom Unit Awards In each of 2018 and 2019 the Compensation Committee approved an additional grant of Phantom Units to each of Messrs. Long and Liuzzi, in each case in recognition of the importance of such NEO to the Partnership’s long term success and to encourage their retention by providing additional time-based compensation. These Phantom Units are referred to as “Retention Units” and were issued pursuant to Retention Phantom Unit Agreements entered into between our General Partner and the applicable NEO on the grant date of the award (the “Retention Agreements”). The Compensation Committee did not award any Retention Units to our NEOs in 2020 or 2021. The Retention Units will vest incrementally, with 60% of the Retention Units vesting on the third December 5 following the grant and 40% on the fifth December 5 following the grant. The Retention Agreements also provide for the vesting of 100% of the then-unvested Retention Units upon (i) the NEO’s termination of employment without Cause or for Good Reason (each as defined in the Retention Agreement and set forth below under “Potential Payments upon Termination or Change in Control”), (ii) a Change in Control (as defined under the LTIP and set forth below under “Potential Payments upon Termination or Change in Control”) or (iii) the death or Disability (as defined under the LTIP and set forth below under “Potential Payments upon Termination or Change in Control”) of the NEO. In addition, Mr. Long’s Retention Agreement provides for vesting of 40% of the outstanding, unvested Phantom Units if Mr. Long voluntarily retires at age 65 or older and has been employed by us, our General Partner, or our or its affiliates for at least 10 years (with the remaining 60% being forfeited). The vesting of the Retention Units are subject, in each case, to the NEO’s continued employment with us until the relevant vesting date. For additional information regarding the Retention Agreements, please see “– Potential Payments upon Termination or Change in Control-Retention Phantom Unit Agreements” below. Benefit Plans and Perquisites We provide the NEOs with certain other benefits and perquisites, which we do not consider to be a significant component of our overall executive compensation program, but which we recognize as an important factor in attracting and retaining talented executives. The NEOs are eligible under the same plans as all other employees with respect to our (i) medical, dental, vision, disability and life insurance benefits and (ii) a defined contribution plan that is tax-qualified under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”). In addition, we currently provide one or more NEOs with an annual automobile allowance and club memberships. The Compensation Committee has determined it is appropriate to offer these perquisites in order to provide compensation opportunities competitive with those offered by similarly situated public companies. In determining the compensation payable to the NEOs, the Compensation Committee considers perquisites in the context of the total compensation the NEOs are eligible to receive. However, given the fact that perquisites represent a relatively small portion of the NEOs’ total compensation, the availability of these perquisites does not materially influence the Compensation Committee’s decision making with respect to other elements of the NEOs’ total compensation. The value of personal benefits and perquisites we provided to each of the NEOs in 2021 is set forth below in “– Summary Compensation Table.” Employment Agreements Each of Messrs. Porter and Kimble is party to an employment agreement with us (together, the “Employment Agreements”), each of which has been extended on a year-to-year basis and will be automatically extended for successive twelve month periods unless either party delivers written notice to the other at least 90 days prior to the end of the current employment term. Please see the description of the Employment Agreements under “Potential Payments upon Termination or Change in Control” for further details on the terms of the Employment Agreements. Risk Assessment Related to Our Compensation Structure We believe our compensation program for all of our employees, including the NEOs, is appropriately structured and not reasonably likely to result in material risk to us because it is structured in a manner that does not promote excessive risk-taking that could damage our reputation, negatively impact our financial results or reward poor judgment. We have also allocated our compensation among base salary and short and long-term compensation in such a way as to not encourage excessive risk-taking. Furthermore, all business groups and employees receive the similar compensation components of base pay and short-term incentives. We typically offer long-term equity incentives to employees at the director level or above, and we use Phantom Units rather than unit options for these equity awards because Phantom Units retain value even in a depressed market, so employees are less likely to take unreasonable risks to get or keep options “in-the-money.” Finally, the time-based vesting over three to five years for our currently outstanding long-term incentive awards ensures that our employees’ interests align with those of our unitholders with respect to our long-term performance. 69 Table of Contents Accounting and Tax Considerations We account for the equity compensation expense for equity awards granted under our LTIP in accordance with GAAP, which requires us to estimate and record an expense for each equity award over the vesting period of the award. For employees, Phantom Units are accounted for as a liability and are re-measured at fair value at the end of each reporting period using the market price of the Partnership’s common units. Phantom Units granted to independent directors do not have a cash settlement option; therefore we account for these awards as equity. During the requisite service period, compensation cost is recognized using the proportionate amount of the award’s fair value that has been earned through service to date. Because we are a partnership and the General Partner is a limited liability company, section 162(m) of the Internal Revenue Code (the “Code”), which generally precludes public corporations from taking a tax deduction for individual compensation to certain of its executive officers in excess of $1 million, does not apply to the compensation paid to the NEOs and, accordingly, the Compensation Committee did not consider its impact in making the compensation recommendations discussed above. Compensation Committee Interlocks and Insider Participation We do not have any Compensation Committee interlocks. Messrs. Joyce, Smith and Waldheim are the only members of the Compensation Committee, and during 2021 neither Mr. Joyce nor Mr. Smith nor Mr. Waldheim was an officer or employee of Energy Transfer or any of its affiliates, or served as an officer of any company with respect to which any of our executive officers served on such company’s board of directors. In addition, neither Mr. Joyce nor Mr. Smith nor Mr. Waldheim is a former employee of Energy Transfer or any of its affiliates.

For the purposes of the following description, the “Company” means USA Compression GP, LLC. The Retention Agreements provide for the vesting of 100% of the then-unvested Retention Units upon (i) the NEO’s termination of employment by the Company without Cause or for separation by the NEO for Good Reason (each as defined in the Retention Agreement and described below), (ii) a Change in Control (as defined under the LTIP and as described below) or (iii) the death or Disability (as defined under the LTIP and as described below) of the NEO. In the event of the NEO’s termination of employment by the Company without Cause or separation by the NEO for Good Reason, provided that the NEO executes and does not revoke a general release and waiver of claims, the NEO will also be entitled to a severance payment intended to capture the value of future distributions associated with Retention Units forfeited for tax withholding purposes upon vesting. Pursuant to the terms of Mr. Long’s Retention Agreements, upon Mr. Long’s termination of employment due to voluntary retirement, provided that Mr. Long is at least 65 years of age at the time of such retirement and has been employed by the Company, the Partnership or their Affiliates for at least 10 years, 40% of his then-outstanding, unvested Retention Units will receive accelerated vesting and the remaining 60% will automatically be forfeited at the time of his retirement pursuant to the terms of Mr. Long’s Retention Agreement. As used in the Retention Agreements, “Cause” means (1) the commission by the NEO of a criminal or other act that involves dishonesty, misrepresentation or moral turpitude; (2) engagement by the NEO in any willful or deliberate misconduct which causes or is reasonably likely to cause economic damage to the Company, the Partnership or any of its and their subsidiaries or injury to the business reputation of the Company, the Partnership or its or their subsidiaries; (3) engagement in any dishonest or fraudulent conduct by the NEO in the performance of the NEO’s duties on behalf of the Company, the Partnership or its or their subsidiaries, including, without limitation, the theft or misappropriation of funds or the disclosure of confidential or proprietary information; (4) a knowing breach by the NEO of any fiduciary duty applicable to the NEO in performance of the NEO’s duties as contained in the organizational documents of the Company, the Partnership or any of its or their subsidiaries; (5) the continuing failure or refusal of the NEO to satisfactorily perform the essential duties of the NEO for the Company; (6) improper conduct materially prejudicial to the business of the Company, the Partnership or any of its or their subsidiaries; (7) the material disregard or violation by the NEO of any policy or procedure of the Company; or (8) any other conduct materially detrimental (as determined in the sole reasonable judgment of the Company) to the Company’s, the Partnership’s or its or their subsidiaries’ business. With respect to a termination for Cause pursuant to clauses (5), (6), (7) and (8) above, such termination will not be considered for Cause unless the NEO has been given written notice specifying in detail the conduct that allegedly constitutes grounds to terminate for Cause and an opportunity for 30 days after receipt of such notice to cure such grounds, if curable. Termination for Cause under clauses (1), (2), (3) or (4) above cannot be cured by the individual and no such notice to cure will be delivered. “Good Reason” is defined under the Retention Agreements as the occurrence, during the Restricted Period (as defined in the Retention Agreement) and without the NEO’s prior written consent, of any one or more of the following: (1) a material reduction in the NEO’s current title; (2) a more than 10% reduction by the Company in the NEO’s rate of annual base salary, annual bonus target or annual long-term incentive target, each determined as of the grant date; (3) a material diminution in the NEO’s authority, duties, reporting relationship or responsibilities that is inconsistent in a material and adverse respect with the NEO’s authority, duties, reporting relationship or responsibilities with the Partnership on the grant date, provided that such material diminution is also accompanied with any associated reduction in the NEO’s annual base salary, annual bonus target or annual long-term incentive target, determined based on the NEO’s highest annual base salary, annual bonus target or annual long-term incentive target during the most recent 365-day period prior to the date the change described in this clause (3) occurs; or (4) a change of 50 miles or more in the geographic location of the NEO’s principal place of employment as of the grant date. For any resignation to be treated as based on “Good Reason” under the Retention Agreement, the following must occur: (x) the NEO must provide written notice to the Company of the existence of the Good Reason condition within a period not to exceed 30 days of the initial existence of the condition; (y) the Company shall have not less than 30 days following its receipt of such during which it may remedy the condition; and (z) the NEO’s termination of employment must occur within the 90 day period after the initial existence of the condition specified in such notice. Further, no act or omission shall be “Good Reason” if the NEO has consented in writing to such act or omission. Employment Agreements As previously noted, each of Messrs.

The NEO’s right to the Severance Payment and continued health insurance benefits described in (i) and (iv) of the preceding sentence are subject to (1) the NEO’s execution of a release of claims against the Company within 45 days of such NEO’s Separation from Service and (2) the NEO’s compliance with the continuing obligations under his Employment Agreement, including confidentiality, non-compete and non-solicit obligations. In the event of the termination of Mr. Porter’s or Mr. Kimble’s employment by the Company without Cause or by the NEO with Good Reason within two years of a “change in control event” within the meaning of Treasury Regulation 1.409A-3(i)(5), the Severance Payment will be paid in a lump sum on the Company’s first regular payroll date that occurs on or after 30 days after the date of the NEO’s Separation from Service.

In the event of the NEO’s death during the Severance Period, the Severance Payment will be paid in a lump sum within 30 days of his death. As used in the Employment Agreements, a termination for “convenience” generally means an involuntary termination for any reason, including, under certain circumstances, a failure to renew the employment agreement at the end of an initial term or any renewal term, other than a termination for “Cause.” “Cause” is defined in the Employment Agreements to mean (i) any material breach of the Employment Agreement, including the material breach of any representation, warranty or covenant made under the Employment Agreement by the NEO, (ii) the NEO’s breach of any applicable duties of loyalty to the Company or any of its affiliates, gross negligence or material misconduct, or a significant act or acts of personal dishonesty or deceit, taken by the NEO, in the performance of the duties and services required of the NEO that is demonstrably and significantly injurious to the Company or any of its affiliates, (iii) conviction of a felony or crime involving moral turpitude, (iv) the NEO’s willful and continued failure or refusal to perform substantially the NEO’s material obligations pursuant to the Employment Agreement or follow any lawful and reasonable directive from the CEO or the Board, as applicable, other than as a result of the NEO’s incapacity, or (v) a violation of federal, state or local law or regulation applicable to the business of the Company that is demonstrably and significantly injurious to the Company. “Good Reason” is defined in Employment Agreements to mean (i) a material breach by the Company of the Employment Agreement or any other material agreement with the NEO, (ii) a material reduction in the NEO’s base salary, other than a reduction that is generally applicable to all similarly situated employees of the Company, (iii) a material reduction in the NEO’s duties, authority, responsibilities, job title or reporting relationships, (iv) a material reduction by the Company in the facilities or perquisites available to the NEO, other than a reduction that is generally applicable to all similarly situated employees, or (v) the relocation of the geographic location of the NEO’s current principal place of employment by more than 50 miles from the location of the NEO’s principal place of employment as of the effective date of the Employment Agreement. “Disability” is defined in the Employment Agreements as the NEO being unable to perform essential functions of his position, with reasonable accommodation, due to an illness or physical or mental impairment or other incapacity which continues for a period in excess of 20 consecutive weeks. The determination of Disability will be made by a physician selected by the NEO and acceptable to the Company or its insurers. Change in Control Benefits – LTIP On November 1, 2018, the Compensation Committee adopted the Phantom Unit Agreement, which (i) provides for incremental vesting of Phantom Units over five years (60% on the third December 5 following the grant and 40% on the fifth December 5 following the grant) and (ii) provides for vesting of 100% of the outstanding, unvested Phantom Units in the event 76 Table of Contents of (a) a Change in Control (as defined under the LTIP and set forth below) or (b) the death or Disability of the NEO. Also, under the Phantom Unit Agreement, if the NEO has been employed by the Company, the Partnership or their Affiliates for at least 10 years and is at least 65 at the time of his voluntary retirement, 60% of his then-unvested Phantom Units will be forfeited, and the remainder will vest, at the time of retirement. If the NEO has been employed by the Company, the Partnership or their Affiliates for at least 10 years and is over age 68 at the time of his voluntary retirement, 50% of his then-unvested Phantom Units will be forfeited, and the remainder will vest, at the time of retirement. For purposes of this description, the “Company” means USA Compression GP, LLC. A “Change in Control” as defined under the LTIP means, with respect to Awards granted on or after April 3, 2018, the occurrence of any of the following events: (i) any “person” or “group” within the meaning of Sections 13(d) and 14(d)(2) of the Exchange Act, other than the Company, Energy Transfer, an Affiliate of the Company (as determined immediately prior to such event), or an Affiliate of, or successor to, Energy Transfer, shall become the beneficial owner, by way of merger, consolidation, recapitalization, reorganization or otherwise, of 50% or more of the combined voting power of the equity interests in the Company or the Partnership; (ii) the limited partners of the Partnership approve, in one or a series of transactions, a plan of complete liquidation of the Partnership; (iii) the sale or other disposition by either the Company or the Partnership of all or substantially all of its assets in one or more transactions to any Person other than the Company, the Partnership, Energy Transfer, an Affiliate of the Company (as determined immediately prior to such event), the Partnership, or an Affiliate of, or successor to, Energy Transfer; or (iv) a transaction resulting in a Person other than the Company, Energy Transfer, an Affiliate of the Company (as determined immediately prior to such event), or an Affiliate of, or successor to, Energy Transfer being the sole general partner of the Partnership. However, if an LTIP award is subject to section 409A of the Code, a “Change in Control” will be defined in accordance with section 409A of the Code and the regulations promulgated thereunder. “Disability” as defined under the LTIP means, as determined by the Compensation Committee in its discretion exercised in good faith, a physical or mental condition of the NEO that would entitle him or her to payment of disability income payments under the Company’s or the Partnership’s or one of its subsidiaries’ long-term disability insurance policy or plan for employees as then in effect; or in the event that an NEO is not covered, for whatever reason, under the Company’s or the Partnership’s or one of its subsidiaries’ long-term disability insurance policy or plan for employees or the Company’s or the Partnership’s or one of its subsidiaries’ does not maintain such a long-term disability insurance policy, “Disability” means a total and permanent disability within the meaning of Section 22(e)(3) of the Code; provided, however, that if a Disability constitutes a payment event with respect to any Award which provides for the deferral of compensation and is subject to section 409A of the Code, then, to the extent required to comply with section 409A of the Code, the NEO must also be considered “disabled” within the meaning of section 409A(a)(2)(C) of the Code. A determination of Disability may be made by a physician selected or approved by the Compensation Committee and, in this respect, NEOs shall submit to an examination by such physician upon request by the Compensation Committee. Potential Payments upon Termination or Change in Control Except as otherwise noted, the values in the table below assume that a Change in Control occurred on December 31, 2021 and/or that the NEO’s employment terminated on that date, as applicable. The amounts actually payable to any NEO can only be calculated with certainty upon actual termination or a Change in Control. Except as otherwise noted, the value of the acceleration of the LTIP awards was calculated using the value of $17.45, which was the closing price of the Partnership’s common units on December 31, 2021. 77 Table of Contents Executive Benefits and Payments Change in Control followed by termination without “Cause” or for “Good Reason” ($) (3) Termination of Employment without “Cause” or for “Good Reason” ($) (3) Termination of Employment because of Death or Disability ($) (4) Termination by the Executive Other Than for “Good Reason” ($) (5) Continued Employment Following Change of Control ($) (6) Eric D.

Porter and Kimble represents his accrued but unused paid time off as of December 31, 2021 plus, with respect to the first two columns, his base salary as of December 31, 2021. Any accrued but unused paid time off owed to Mr. Porter or Mr. Kimble would be paid within 30 days of the date of his termination of employment, and the base salary would be paid out as set forth in footnote (3). 78 Table of Contents (2) The listed bonus amount for each of Messrs. Kimble and Porter is his pro rata bonus awarded with respect to the year ended December 31, 2021 and his bonus awarded with respect to the year ended December 31, 2020. (3) The Employment Agreements for each of Messrs. Porter and Kimble provide that upon termination by the Company without Cause or by the NEO for Good Reason, the NEO is entitled to receive one times his base salary, payable in equal semi-monthly installments over the course of one year. Upon the death of Mr. Porter or Mr. Kimble during this one year period, his salary payment will be accelerated and all remaining Severance Payments (as defined in the Employment Agreements) would be paid in a lump sum within 30 days of his death. If such termination occurs within two years after a “change in control event” within the meaning of Treasury Regulation 1.409A-3(i)(5), the Severance Payment will be made in a lump sum on the first regular payroll date that occurs on or after 30 days of the NEO’s termination date. (4) Upon the death or Disability (as defined in the Employment Agreements) of Mr. Porter or Mr. Kimble, he (or his estate) will be entitled to the same bonus payment as if the death or Disability had not occurred. (5) In the event of the termination of employment by any of the NEOs without Good Reason, the NEO will be entitled to all earned but unpaid annual base salary. None of the NEOs had earned but unpaid annual base salary as of December 31, 2021. (6) The NEOs are not entitled to a certain level of compensation in the event of continued employment following a Change in Control, but for purposes of this table it is assumed that the NEO would continue to receive a level of base salary, bonus, benefits and other compensation in the event of continued employment following a Change in Control that is the same as, or similar to, the amounts shown in the Summary Compensation Table. Accordingly, no additional amounts are shown for salary, bonus or health and welfare plan benefits because those amounts would remain as in effect at the time of the Change in Control, and only the acceleration values of outstanding equity at the time of a Change of Control have been reflected. (7) In the event of Mr. Porter’s or Mr. Kimble’s termination by the Company without Cause or by the NEO with Good Reason, he and his eligible dependents will be entitled to continued health insurance benefits for the Coverage Period, as follows: (a) for the first 12 months of the Coverage Period, the Company will provide such health insurance coverage at its own expense (other than the NEO’s monthly cost-sharing contribution under the Company’s group health plan, as in effect at the time of the NEO’s Separation from Service); (b) for the following six months of the Coverage Period, such health insurance coverage will be at the NEO’s sole expense; and (c) for the final six months of the Coverage Period, the Company will be responsible for the proportion of the cost of such health insurance coverage that the NEO covered in the first 12 months of the Coverage Period; and the NEO will be responsible for the proportion that the Company covered during the first 12 months of the Coverage Period. Messrs. Long, Liuzzi and Scheller are not currently party to any contractual arrangements providing for continued health insurance coverage by the Company following a termination of employment. (8) In the event of the NEO’s cessation of service for any reason (other than death or Disability), 100% of the NEO’s Phantom Units that have not vested prior to or in connection with such cessation of service shall be automatically forfeited. Notwithstanding the foregoing, with respect to the Phantom Units granted on December 5, 2018, December 5, 2019, December 5, 2020 and December 5, 2021 (collectively, the “December LTIP Phantom Units”), if the NEO retires after attaining the age of 65, 60% of his then-unvested December LTIP Phantom Units will be forfeited, and the remainder will vest, at the time of retirement and, if the NEO is over age 68 at the time of retirement, 50% of his then-unvested December LTIP Phantom Units will be forfeited, and the remainder will vest, at the time of retirement. In the event of the death or Disability (as defined under the LTIP) of the NEO, 100% of the then-unvested December LTIP Phantom Units shall vest in full immediately prior to such NEO’s cessation of service due to death or Disability. In the event of a Change in Control (as defined under the LTIP), 100% of the NEO’s outstanding, unvested December LTIP Phantom Units would vest. (9) The Retention Agreements for Messrs. Long and Liuzzi provide that 100% of the outstanding, unvested Retention Units held by the applicable NEO will vest immediately prior to the NEO’s Separation from Service for the following reasons: (i) termination of the NEO by the Company without Cause or by the NEO with Good Reason, (ii) upon a Change in Control, and (iii) upon the death or Disability of the NEO. Also, if Mr. Long terminates his employment due to retirement and he is at the time of retirement 65 years of age or older, 40% of his then-unvested Retention Units will vest and the remaining 60% of his then-unvested Retention Units will be forfeited. (10) For Messrs. Long and Liuzzi, provided that the NEO executes and does not revoke a general release and waiver of claims, the NEO will be entitled to a severance payment intended to capture the value of future distributions associated with Retention Units forfeited for tax withholding purposes, which payment would be paid within 60 days of the NEO’s date of separation. The tax withholding rate as of December 31, 2021 for each of the NEOs applicable to the vesting of the Retention Units would have been 39.35%. CEO Pay Ratio Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, require us to provide certain information about the relationship of the annual total compensation of our employees and the annual total compensation of our Chief Executive Officer, Eric Long (our “CEO”). The employees providing services to us are directly employed by USAC Management, therefore we do not have employees for purposes of the pay ratio rules. Rather than providing a pay ratio disclosure that contemplates no employees, we have determined that the disclosure that would be most aligned with the spirit of the pay ratio rules and that would provide our unitholders with more meaningful information would be to provide a ratio using the median employee from the USAC Management employee population. All references to “our” employees within this section shall refer to the applicable USAC Management employees. In accordance with Item 402(u), we are basing the following pay-ratio information on the same median employee that we selected in 2020. There has been no change in our employee population or employee compensation arrangements that we believe would result in a significant change to our pay ratio disclosure for 2021. 79 Table of Contents For 2021, our last completed fiscal year: • The median of the annual total compensation of all employees (other than the CEO) was $105,042. • The annual total compensation of our CEO, as reported in the Summary Compensation Table included elsewhere within this Form 10-K, was $5,759,051. • Based on this information, for 2021 the ratio of the annual total compensation of Mr. Long to the median of the annual total compensation of all employees was reasonably estimated to be 54.8 to 1. To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee and our CEO, we took the following steps: • We determined that, as of December 31, 2020, our employee population consisted of approximately 742 individuals with all of these individuals located in the U.S. This population consisted of our full-time employees, as we do not have any part-time employees, temporary employees, or seasonal workers. • We selected December 31, 2020 as our identification date for determining our median employee because it enabled us to make such identification in a reasonably efficient and economic manner. • We used a consistently applied compensation measure to identify our median employee of comparing the amount of salary or wages, bonuses, compensation received from equity award vesting, and any other compensation items reported to the Internal Revenue Service on Form W-2 for 2020. • We identified our median employee by consistently applying this compensation measure to all of our employees included in our analysis. Since all of our employees, including our CEO, are located in the U.S., we did not make any cost of living adjustments in identifying the median employee. • After we identified our median employee, we combined all of the elements of such employee’s compensation for the 2021 year in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $105,042. • With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2021 Summary Compensation Table included in this Form 10-K. Director Compensation For the year ended December 31, 2021, our CEO was the only NEO who also served as a director, and he did not receive additional compensation for his service on the Board. Mr. Long’s compensation as an NEO is reflected in the Summary Compensation Table above. Officers, employees or paid consultants or advisors of us or the General Partner or its affiliates who also serve as directors do not receive additional compensation for their service as directors. Other than Mr. Hartman, our directors who are not officers, employees or paid consultants or advisors of us or the General Partner or its affiliates receive cash and equity based compensation for their services as directors. Our director compensation program is subject to revision by the Board from time to time. The following table shows the total fees earned and other compensation paid in cash to each independent director during 2021.

For a detailed discussion of the assumptions utilized in coming to these values, please see Note 14 in Part II, Item 8 “Financial Statements and Supplementary Data”. As of December 31, 2021, the independent members of the Board who receive equity awards held the following number of outstanding equity awards under the LTIP: Mr. Joyce: 19,619 Phantom Units; Mr. Smith: 2,500 Phantom Units and Mr. Waldheim: 19,619 Phantom Units. The Phantom Units granted in 2021 to Messrs. Joyce, Smith and Waldheim vest incrementally, with 60% of the Phantom Units vesting on December 5, 2023 and the remaining 40% of the Phantom Units vesting on December 5, 2025. In the event of the director’s cessation of service due to death, Disability or a Change in Control, 100% of his outstanding, unvested Phantom Units will vest immediately prior to such event. 80 Table of Contents (2) Amounts in this column reflect the value of DERs, received by the directors with respect to their outstanding Phantom Unit awards. For Messrs. Joyce, Smith and Waldheim, the amount shown includes DERs paid with respect to the Partnership’s quarterly distribution on its common units with respect to each quarter in the 2021 year that such director held Phantom Units. (3) Mr. Hartman was appointed to the Board pursuant to that certain Board Representation Agreement entered to among us, the General Partner, Energy Transfer and EIG on the Transactions Date in connection with our private placement to EIG of Preferred Units and Warrants. Mr. Hartman does not receive compensation for his service on the Board. (4) Mr. Smith was appointed to the Board on April 30, 2021, therefore he received cash compensation related to his service for the second, third and fourth quarters of 2021. On July 30, 2018 the Board adopted the Amended and Restated Outside Director Compensation Policy (the “Director Compensation Policy”), which provides for: (i) an annual cash retainer of $100,000; (ii) an annual cash retainer for acting as the Chairman of the Audit Committee and for acting as Chairman of the Compensation Committee; (iii) an annual cash retainer for membership on the Audit Committee or Compensation Committee; (iv) an undetermined fixed sum for membership on a special or conflicts committee; (v) an annual equity grant with a value of $100,000; and (vi) a one-time director onboarding equity award of 2,500 Phantom Units. The Phantom Units granted pursuant to the Director Compensation Policy vest incrementally over five years and all outstanding, unvested Phantom Units vest in full in the event of the director’s death, Disability or upon a Change in Control (each as defined in the LTIP). The Director Compensation Policy does not provide for per meeting attendance fees. The following chart summarizes the Director Compensation Policy.

Securities Authorized for Issuance Under Equity Compensation Plans The Board adopted the LTIP in January 2013. On November 1, 2018, the Board approved and adopted the First Amendment to the LTIP (the “First Amendment”) with immediate effectiveness. The First Amendment (i) increased the number of common units available to be awarded under the LTIP by 8,590,000 common units (which brought the total number of common units available to be awarded under the LTIP to 10,000,000 common units); (ii) provided that common units withheld to satisfy the exercise price or tax withholding obligations with respect to an award will not be considered to be common units that have been delivered under the LTIP; (iii) for awards granted on or after April 3, 2018, modifies the definition of “Change in Control” under the LTIP to refer to Energy Transfer and its Affiliates (as defined under the LTIP) and successors; (iv) updated the tax withholding provision of the LTIP and (v) extended the term of the LTIP until November 1, 2028. The following table provides certain information with respect to the LTIP as of December 31, 2021: Plan Category Number of securities to be issued upon exercise of outstanding options, warrants and rights Weighted-average exercise price of outstanding options, warrants and rights Number of securities remaining available for future issuance under equity compensation plan (excluding securities reflected in the first column) Equity compensation plans approved by security holders — N/A — Equity compensation plans not approved by security holders 2,229,768 N/A 5,971,579 (1) ________________________ (1) As of December 31, 2021, we had 8,201,347 common units available under the LTIP before giving effect to the outstanding awards of 2,229,768 Phantom Units.

Additionally, Phantom Units withheld to satisfy the exercise price or tax withholdings of an award and Phantom Units that are forfeited, cancelled, or otherwise terminate or expire without the actual delivery of common units will be available for delivery pursuant to other awards. For more information about the LTIP, please see Note 14 in Part II, Item 8 “Financial Statements and Supplementary Data”. ITEM 13. Certain Relationships and Related Party Transactions, and Director Independence Certain Relationships and Related Party Transactions Services Agreement We and other parties have entered into the agreements described below. These agreements were not the result of arm’s length negotiations, and they, or any of the transactions that they provide for, may not be effected on terms as favorable to the parties to these agreements as could have been obtained from unaffiliated third parties. We entered into that certain Services Agreement with USAC Management, a wholly owned subsidiary of the General Partner, effective on January 1, 2013 (the “Services Agreement”), pursuant to which USAC Management provides to us and the General Partner management, administrative and operating services and personnel to manage and operate our business. We or one of our subsidiaries pays USAC Management for the allocable expenses it incurs in its performance under the Services Agreement. These expenses include, among other things, salary, bonus, cash incentive compensation and other amounts paid to 83 Table of Contents persons who perform services for us or on our behalf and other expenses allocated by USAC Management to us. USAC Management has substantial discretion to determine in good faith which expenses to incur on our behalf and what portion to allocate to us. On November 3, 2017, the Services Agreement was amended to extend its term to December 31, 2022. The Services Agreement may be terminated at any time by (i) the Board upon 120 days’ written notice for any reason in its sole discretion or (ii) USAC Management upon 120 days’ written notice if: (a) we or the General Partner experience a Change of Control (as defined in the Services Agreement); (b) we or the General Partner breach the terms of the Services Agreement in any material respect following 30 days’ written notice detailing the breach (which breach remains uncured after such period); (c) a receiver is appointed for all or substantially all of our or the General Partner’s property or an order is made to wind up our or the General Partner’s business; (d) a final judgment, order or decree that materially and adversely affects the ability of us or the General Partner to perform under the Services Agreement is obtained or entered against us or the General Partner, and such judgment, order or decree is not vacated, discharged or stayed; or (e) certain events of bankruptcy, insolvency or reorganization of us or the General Partner occur. USAC Management will not be liable to us for their performance of, or failure to perform, services under the Services Agreement unless its acts or omissions constitute gross negligence or willful misconduct. Transactions with Energy Transfer We provide compression services to entities affiliated with Energy Transfer, which became a related party of ours on the Transactions Date. As of December 31, 2021, Energy Transfer has ownership and control of the General Partner and ownership of approximately 47% of our limited partner interests (including the 8,000,000 common units owned by the General Partner). We recognized $12.0 million in revenue from compression services from entities affiliated with Energy Transfer for the year ended December 31, 2021. We may provide compression services to entities affiliated with Energy Transfer in the future, and any significant transactions will be disclosed. The following table summarizes payments, revenues and other receivables between us and Energy Transfer during 2021. Transaction Explanation Amount/Value 2021 quarterly distributions on limited partner interests Represents the aggregate amount of distributions made to Energy Transfer in respect of the Partnership’s common units during 2021. $ 96.7 million Revenue for compression services Represents the aggregate amount of revenue recognized for providing compression services to entities affiliated with Energy Transfer for the full year 2021. $ 12.0 million Sales Tax Contingency Receivable from Energy Transfer as of December 31, 2021 related to indemnification for sales tax contingencies incurred. $ 44.9 million Conflicts of Interest Conflicts of interest exist and may arise in the future as a result of the relationships between the General Partner and its affiliates, including Energy Transfer, on the one hand, and the Partnership and its limited partners, on the other hand. The directors and officers of the General Partner have fiduciary duties to manage the General Partner in a manner beneficial to its owners. At the same time, the General Partner has a fiduciary duty to manage the Partnership in a manner beneficial to us and our unitholders. Whenever a conflict arises between the General Partner or its affiliates, on the one hand, and the Partnership and its limited partners, on the other hand, the General Partner will resolve that conflict. The Partnership Agreement contains provisions that modify and limit the General Partner’s fiduciary duties to the Partnership’s unitholders. The Partnership Agreement also restricts the remedies available to the Partnership’s unitholders for actions taken by the General Partner that, without those limitations, might constitute breaches of its fiduciary duty. The Partnership Agreement provides that the General Partner will not be in breach of its obligations under the Partnership Agreement or its fiduciary duties to us or our unitholders if a transaction with an affiliate or the resolution of a conflict of interest is (a) approved by the conflicts committee of the Board, although the General Partner is not obligated to seek such approval; (b) approved by the vote of a majority of our outstanding common units, excluding any common units owned by the General Partner and its affiliates; (c) on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or (d) fair and reasonable to us, taking into account the totality of the relationships among the parties involved, including other transactions that may be particularly favorable or advantageous to us. 84 Table of Contents The General Partner may, but is not required to, seek the approval of such resolution from the conflicts committee of the Board. In connection with a situation involving a conflict of interest, any determination by the General Partner must be made in good faith, provided that, if the General Partner does not seek approval from the conflicts committee and the Board determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in subclauses (c) or (d) above, then it will conclusively be deemed that, in making its decision, the Board acted in good faith. Unless the resolution of a conflict is specifically provided for in the Partnership Agreement, the General Partner or the conflicts committee may consider any factors that it determines in good faith to be appropriate when resolving a conflict. When the Partnership Agreement provides that someone act in good faith, it requires that person to reasonably believe he is acting in the best interests of the Partnership. Please read Part I, Item 1A “Risk Factors – Risks Inherent in an Investment in Us”. Procedures for Review, Approval and Ratification of Related Person Transactions If a conflict or potential conflict of interest arises between the General Partner and its affiliates, including Energy Transfer, on the one hand and the Partnership and its limited partners, on the other hand, the resolution of any such conflict or potential conflict is addressed as described under “Conflicts of Interest.” Pursuant to the Partnership’s Code of Business Conduct and Ethics and Corporate Governance Guidelines, directors, officers and employees are required to disclose any situations that reasonably would be expected to give rise to a conflict of interest and report it to their supervisor, the Partnership’s general counsel or the Board, as appropriate. Director Independence Please see Part III, Item 10 “Directors, Executive Officers and Corporate Governance – Board of Directors” for a discussion of director independence matters. ITEM 14.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Partnership as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Partnership’s internal control over financial reporting as of December 31, 2021, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 15, 2022 expressed an unqualified opinion. Basis for opinion These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on the Partnership’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 Partnership 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 matters Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters. /s/ GRANT THORNTON LLP We have served as the Partnership’s auditor since 2017.

F-6 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements (1) Organization and Description of Business Unless otherwise indicated, the terms “our,” “we,” “us,” “the Partnership” and similar language refer to USA Compression Partners, LP, collectively with its consolidated subsidiaries. We are a Delaware limited partnership. Through our operating subsidiaries, we provide compression services under fixed-term contracts with customers in the natural gas and crude oil industries, using natural gas compression packages that we design, engineer, own, operate and maintain. We also own and operate a fleet of equipment used to provide natural gas treating services, such as carbon dioxide and hydrogen sulfide removal, cooling, and dehydration. We primarily provide compression services in a number of shale plays throughout the U.S., including the Utica, Marcellus, Permian Basin, Delaware Basin, Eagle Ford, Mississippi Lime, Granite Wash, Woodford, Barnett, Haynesville, Niobrara and Fayetteville shales. USA Compression GP, LLC, a Delaware limited liability company, serves as our general partner and is referred to herein as the “General Partner.” The General Partner is wholly owned by Energy Transfer. The Partnership is a borrower under a revolving credit facility and its subsidiaries are guarantors of that revolving credit facility (see Note 9). The accompanying consolidated financial statements include the accounts of the Partnership and its subsidiaries, all of which are wholly owned by us. Net loss attributable to partners is allocated to our common units and participating securities using the two-class income allocation method. All intercompany balances and transactions have been eliminated in consolidation. Our common units trade on the New York Stock Exchange under the ticker symbol “USAC”. USA Compression Management Services, LLC (“USAC Management”), a wholly owned subsidiary of the General Partner, performs certain management and other administrative services for us, such as accounting, corporate development, finance and legal. All of our employees, including our executive officers, are employees of USAC Management. As of December 31, 2021, USAC Management had 697 full time employees. None of our employees are subject to collective bargaining agreements. (2) Basis of Presentation and Accounting Policies Basis of Presentation Our accompanying consolidated financial statements have been prepared in conformity with GAAP and pursuant to the rules and regulations of the SEC. Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and the accompanying results. Although these estimates are based on management’s available knowledge of current and expected future events, actual results could differ from these estimates. Accounting Policies Cash and Cash Equivalents Cash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of 90 days or less to be cash equivalents. Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount. Allowance for Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (“Topic 326”): Measurement of Credit Losses on Financial Instruments . On January 1, 2020, we adopted Topic 326 using the modified retrospective approach, which was effective for interim and annual reporting periods beginning on or after December 15, 2019. Topic 326 requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. F-7 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements To adopt Topic 326, we evaluated our allowance for credit losses related to our two financial assets measured at amortized cost: (i) trade accounts receivable and (ii) net investment in lease related to our sales-type lease discussed further in Note 7. Due to the short-term nature of our trade accounts receivable, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. There was no cumulative effect adjustment to partners’ capital upon adoption. Our determination of the allowance for credit losses requires us to make estimates and judgments regarding our customers’ ability to pay amounts due. We continuously evaluate the financial strength of our customers and the overall business climate in which our customers operate, and make adjustments to the allowance for credit losses as necessary. We evaluate the financial strength of our customers by reviewing the aging of their receivables, our collection experience with the customer, correspondence, financial information and third-party credit ratings. We evaluate the business climate in which our customers operate by reviewing various publicly available materials regarding our customers’ industry, including the solvency of various companies in the industry. Inventories Inventories consist of serialized and non-serialized parts used primarily on compression units. All inventories are stated at the lower of cost or net realizable value. Serialized parts inventories are determined using the specific identification cost method, while non-serialized parts inventories are determined using the weighted average cost method. Purchases of inventories are considered operating activities in the Consolidated Statements of Cash Flows. Property and Equipment Property and equipment are carried at cost except for (i) certain acquired assets which are recorded at fair value on their respective acquisition dates and (ii) impaired assets which are recorded at fair value on the last impairment evaluation date for which an adjustment was required. Overhauls and major improvements that increase the value or extend the life of compression equipment are capitalized and depreciated over three to five years . Ordinary maintenance and repairs are charged to cost of operations, exclusive of depreciation and amortization. When property and equipment is retired or sold, its carrying value and the related accumulated depreciation are removed from our accounts and any associated gains or losses are recorded on our statements of operations in the period of sale or disposition. Capitalized interest is calculated by multiplying our monthly effective interest rate on outstanding debt by the amount of qualifying costs, which include upfront payments to acquire certain compression units. Capitalized interest was $ 0.2 million, $ 0.2 million and $ 0.5 million for the years ended December 31, 2021, 2020 and 2019, respectively. Impairments of Long-Lived Assets Long-lived assets with recorded values that are not expected to be recovered through future cash flows are written-down to estimated fair value. We test long-lived assets for impairment when events or circumstances indicate that the assets’ carrying value may not be recoverable or will no longer be utilized in the operating fleet. The most common circumstance requiring compression units to be evaluated for impairment is when idle units do not meet the desired performance characteristics of our active revenue generating horsepower. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value of the long-lived asset exceeds the sum of the undiscounted cash flows associated with the asset, an impairment loss equal to the amount of the carrying value exceeding the fair value of the asset is recognized. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units we recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use. In the first quarter of 2020, we determined that the impairment of our goodwill was an indicator of potential impairment of the carrying amount of our long-lived assets. Accordingly, we performed a quantitative impairment test of our long-lived assets, by which we determined that they were not also impaired. No triggering events have been identified subsequent to the first quarter of 2020. Refer to Note 5 for more detailed information about impairment charges during the years ended December 31, 2021, 2020 and 2019. F-8 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements Identifiable Intangible Assets Identifiable intangible assets are recorded at cost and amortized using the straight-line method over their estimated useful lives, which is the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The estimated useful lives of our intangible assets range from 15 to 25 years. We assess identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the first quarter of 2020, we determined that the impairment of our goodwill was an indicator of potential impairment of the carrying amount of our identifiable intangible assets. Accordingly, we performed a quantitative impairment test of our identifiable intangible assets, by which we determined that they were not also impaired. No triggering events have been identified subsequent to the first quarter of 2020. We did no t record any impairment of identifiable intangible assets for the years ended December 31, 2021, 2020 or 2019. Goodwill Goodwill represents consideration paid in excess of the fair value of the identifiable net assets acquired in a business combination. Goodwill is not amortized, but is reviewed for impairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwill may not be recovered. We recorded a $ 619.4 million goodwill impairment for the year ended December 31, 2020, which reduced our goodwill balance to zero, and did no t record any goodwill impairment during the year ended December 31, 2019. Refer to the Goodwill section in Note 5 for more information about the goodwill impairment assessment performed during the years ended December 31, 2020 and 2019. Revenue Recognition Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services or goods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Incidental items, if any, that are immaterial in the context of the contract are recognized as expenses. Refer to Note 12 for more detailed information about revenue recognition for the years ended December 31, 2021, 2020 and 2019. Income Taxes We are organized as a partnership for U.S. federal and state income tax purposes. As a result, our partners are responsible for U.S. federal and state income taxes based upon their distributive share of our items of income, gain, loss, or deduction. Texas imposes an entity-level income tax on partnerships that is based on Texas sourced taxable margin (the “Texas Margin Tax”). We have included in the consolidated financial statements a provision for Texas Margin Tax. Refer to Note 8 for more detailed information about the Texas Margin Tax for the years ended December 31, 2021, 2020 and 2019. Pass Through Taxes Sales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis. Fair Value Measurements Accounting standards on fair value measurements establish a framework for measuring fair value and stipulate disclosures about fair value measurements. The standards apply to recurring and non-recurring financial and non-financial assets and liabilities that require or permit fair value measurements. Among the required disclosures is the fair value hierarchy of inputs we use to value an asset or a liability. The three levels of the fair value hierarchy are described as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. As of December 31, 2021, our financial instruments consisted primarily of cash and cash equivalents, trade accounts receivable, trade accounts payable and long-term debt. The book values of cash and cash equivalents, trade accounts receivable, F-9 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements and trade accounts payable are representative of fair value due to their short-term maturities. The carrying amount of our revolving credit facility approximates fair value due to the floating interest rates associated with the debt. The fair value of our Senior Notes 2026 and Senior Notes 2027 were estimated using quoted prices in inactive markets and are considered Level 2 measurements. The following table summarizes the aggregate principal amount and fair value of our Senior Notes 2026 and Senior Notes 2027 (in thousands): December 31, 2021 2020 Senior Notes 2026, aggregate principal $ 725,000 $ 725,000 Fair value of Senior Notes 2026 755,813 761,250 Senior Notes 2027, aggregate principal 750,000 750,000 Fair value of Senior Notes 2027 787,500 800,625 Nonrecurring Fair Value Measurements During the first quarter of 2020 certain potential impairment indicators were identified, specifically (i) the decline in the market price of our common units, (ii) the decline in global commodity prices and (iii) the COVID-19 pandemic; which together indicated the fair value of the reporting unit was less than its carrying amount as of March 31, 2020. We performed a quantitative impairment test as of March 31, 2020 that resulted in a goodwill impairment of $ 619.4 million for the year ended December 31, 2020. Significant estimates used in our goodwill impairment analysis included cash flow forecasts, our estimate of the market’s weighted average cost of capital and market multiples, which are Level 3 inputs. Refer to Note 5 for further information on our goodwill impairment analysis. Operating Segment We operate in a single business segment, the compression services business. (3) Trade Accounts Receivable The allowance for credit losses, which was $ 2.1 million and $ 5.0 million as of December 31, 2021 and 2020, respectively, is our best estimate of the amount of probable credit losses included in our existing accounts receivable. The following summarizes activity within our trade accounts receivable allowance for credit losses balance (in thousands): Allowance for Credit Losses (1) Balance, December 31, 2019 $ 2,479 Current-period provision for expected credit losses 3,700 Writeoffs charged against the allowance ( 1,197 ) Balance, December 31, 2020 4,982 Current-period provision for expected credit losses ( 2,700 ) Writeoffs charged against the allowance ( 264 ) Recoveries collected 39 Balance, December 31, 2021 $ 2,057 ________________________ (1) On January 1, 2020, we adopted Topic 326 using the modified retrospective approach, refer to Note 2 for more information. Improved market conditions for customers due to the recovery in commodity prices during 2021 was the primary factor contributing to the decrease to the allowance for credit losses for the year ended December 31, 2021. The potential negative impact to our customers of low commodity prices during 2020, driven by decreased demand for and global oversupply of crude oil as a result of the COVID-19 pandemic, was the primary factor contributing to the increase to the allowance for credit losses for the year ended December 31, 2020. F-10 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements During the year ended December 31, 2019, we recorded $ 1.1 million to the current-period provision for expected credit losses. (4) Inventories Components of inventories were as follows (in thousands): December 31, 2021 2020 Serialized parts $ 44,642 $ 42,233 Non-serialized parts 41,174 42,399 Total inventories $ 85,816 $ 84,632 (5) Property and Equipment, Identifiable Intangible Assets and Goodwill Property and Equipment Property and equipment consisted of the following (in thousands): December 31, 2021 2020 Compression and treating equipment $ 3,522,083 $ 3,480,660 Computer equipment 54,013 53,887 Automobiles and vehicles 31,919 33,412 Leasehold improvements 8,847 8,218 Buildings 5,334 5,334 Furniture and fixtures 1,105 1,110 Land 77 77 Total property and equipment, gross 3,623,378 3,582,698 Less: accumulated depreciation and amortization ( 1,401,042 ) ( 1,202,065 ) Total property and equipment, net $ 2,222,336 $ 2,380,633 Depreciation is calculated using the straight-line method over the estimated useful lives of the assets as follows: Compression equipment, acquired new 25 years Compression equipment, acquired used 5 - 25 years Furniture and fixtures 3 - 10 years Vehicles and computer equipment 1 - 10 years Buildings 5 years Leasehold improvements 5 years Depreciation expense on property and equipment was $ 209.4 million, $ 209.6 million and $ 202.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. During the years ended December 31, 2021, there was a gain on disposition of assets of $ 2.6 million. During the years ended December 31, 2020 and 2019, there was a loss on disposition of assets of $ 0.1 million and $ 0.9 million, respectively. For the years ended December 31, 2021, 2020 and 2019, we evaluated the future deployment of our idle fleet under current market conditions and determined to retire 26 , 37 and 33 compressor units, respectively, for a total of approximately 11,000 , 15,000 and 11,000 horsepower, respectively, that were previously used to provide compression services in our business. As a result, we recorded impairments of compression equipment of $ 5.1 million, $ 8.1 million and $ 5.9 million for the years ended December 31, 2021, 2020 and 2019, respectively. The primary causes for these impairments were: (i) units were not considered marketable in the foreseeable future, (ii) units were subject to excessive maintenance costs or (iii) units were unlikely to be accepted by customers due to certain performance F-11 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements characteristics of the unit, such as the inability to meet current quoting criteria without excessive retrofitting costs. These compression units were written down to their respective estimated salvage values, if any. Identifiable Intangible Assets Identifiable intangible assets, net consisted of the following (in thousands): Customer Relationships Trade Names Total Gross balance at December 31, 2019 $ 485,162 $ 65,500 $ 550,662 Accumulated amortization ( 182,210 ) ( 34,661 ) ( 216,871 ) Net balance at December 31, 2020 $ 302,952 $ 30,839 $ 333,791 Gross balance at December 31, 2020 $ 485,162 $ 65,500 $ 550,662 Accumulated amortization ( 208,314 ) ( 37,937 ) ( 246,251 ) Net balance at December 31, 2021 $ 276,848 $ 27,563 $ 304,411 Amortization expense for the years ended December 31, 2021, 2020 and 2019 was $ 29.4 million, $ 29.4 million and $ 29.4 million, respectively. The expected amortization of the intangible assets for each of the five succeeding years is $ 29.4 million. Goodwill During the first quarter of 2020 certain potential impairment indicators were identified, specifically (i) the decline in the market price of our common units, (ii) the decline in global commodity prices and (iii) the COVID-19 pandemic; which together indicated the fair value of the reporting unit was less than its carrying amount as of March 31, 2020. We performed a quantitative goodwill impairment test as of March 31, 2020 and determined fair value using a weighted combination of the income approach and the market approach. Determining fair value of a reporting unit requires judgment and use of significant estimates and assumptions. Such estimates and assumptions include revenue growth rates, EBITDA margins, weighted average costs of capital and future market conditions, among others. We believe the estimates and assumptions used were reasonable and based on available market information, but variations in any of the assumptions could have resulted in materially different calculations of fair value and determinations of whether or not an impairment is indicated. Under the income approach, we determined fair value based on estimated future cash flows, including estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflects the overall level of inherent risk of the Partnership. Cash flow projections were derived from four-year operating forecasts plus an estimate of later period cash flows, all of which were developed by management. Subsequent period cash flows were developed using growth rates that management believed were reasonably likely to occur. Under the market approach, we determined fair value by applying valuation multiples of comparable publicly-traded companies to the projected EBITDA of the Partnership and then averaging that estimate with similar historical calculations using a three-year average. In addition, we estimated a reasonable control premium representing the incremental value that would accrue to us if we were to be acquired. Based on the quantitative goodwill impairment test described above, our carrying amount exceeded fair value and as a result, we recognized a goodwill impairment of $ 619.4 million for the year ended December 31, 2020. As of October 1, 2019, we performed a qualitative assessment of relevant events and circumstances potentially indicating the likelihood of goodwill impairment. The qualitative assessment included weighting such factors as (i) macroeconomic conditions, (ii) industry and market considerations, (iii) cost factors, (iv) overall financial performance of the reporting unit, (v) other relevant entity-specific events, and (vi) consideration of whether there was a sustained decrease in the price of our units. Upon completion of our qualitative assessment, we concluded that it was not more likely than not that the fair value of our single reporting unit was less than its carrying value and that our goodwill was no t impaired for the year ended December 31, 2019. F-12 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements (6) Other Current Liabilities Components of other current liabilities included the following (in thousands): December 31, 2021 2020 Accrued sales tax contingencies (1) $ 44,923 $ 44,923 Accrued interest expense 30,850 31,125 Accrued payroll and benefits 8,054 8,416 Accrued unit-based compensation liability 13,280 9,183 ________________________ (1) Refer to Note 16 for further detailed information on the accrued sales tax contingencies. (7) Lease Accounting On January 1, 2019, we adopted FASB Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC Topic 842”). ASC Topic 842 requires entities to recognize lease assets and liabilities on the balance sheet for all leases with a term of more than one year, including operating leases, which historically were not recorded on the balance sheet in accordance with the prior standard. Lessee Accounting We maintain both finance leases and operating leases, primarily related to office space, warehouse facilities and certain corporate equipment. Our leases have remaining lease terms of up to eight years , some of which include options that permit renewals for additional periods. We determine if an arrangement is a lease at inception. Operating leases are included in lease right-of-use (“ROU”) assets, accrued liabilities and operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, accrued liabilities and other liabilities in our consolidated balance sheets. ROU lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU lease assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. ROU lease assets also include any lease payments made and exclude lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. 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. For short-term leases (leases that have terms of twelve months or less upon commencement), lease payments are recognized on a straight line basis and no ROU assets are recorded. For certain equipment leases, such as office equipment, we account for the lease and non-lease components as a single lease component.

Lessor Accounting We granted a bargain purchase option to a customer with respect to certain compressor packages leased to the customer. The bargain purchase option provides the customer with an option to acquire the equipment at a value significantly less than the fair market value at the end of the lease term. During 2021, the customer exercised its bargain purchase option resulting in a gain of $ 1.1 million recognized within loss (gain) on disposition of assets for the year ended December 31, 2021. We accounted for this option as a sales type lease resulting in a current installment receivable included in other accounts receivable of $ 2.9 million as of December 31, 2020. Prior to the customer exercising its bargain purchase option, revenue and interest income related to the lease was recognized over the lease term. We recognized maintenance revenue within contract operations revenue and interest income within interest expense, net. Maintenance revenue recognized for the years ended December 31, 2021, 2020 and 2019 was F-15 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements $ 0.3 million, $ 1.3 million and $ 1.3 million, respectively. Interest income recognized for the years ended December 31, 2021, 2020 and 2019 was $ 0.1 million, $ 0.4 million and $ 0.7 million, respectively. ASC Topic 842 provides lessors with a practical expedient to not separate non-lease components from the associated lease components and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under ASC Topic 606 Revenue from Contracts with Customers (“ASC Topic 606”) and certain conditions are met. Our contract operations services agreements meet these conditions and we consider the predominant component to be the non-lease components, resulting in the ongoing recognition of revenue following ASC Topic 606 guidance. (8) Income Tax Expense (Benefit) We are subject to the Texas Margin Tax, which applies a tax to our gross margin. We do not conduct business in any other state where a similar tax is applied. The Texas Margin Tax requires certain forms of legal entities, including limited partnerships, to pay a tax of 0.75 % on its “margin,” as defined in the law, based on annual results. The tax base to which the tax is applied is the least of (i) 70 % of total revenues for federal income tax purposes, (ii) total revenue less cost of goods sold or (iii) total revenue less compensation for federal income tax purposes. Components of our income tax expense are as follows (in thousands): Year Ended December 31, 2021 2020 2019 Current tax expense $ 916 $ 803 $ 810 Deferred tax expense (benefit) ( 42 ) 530 1,376 Total income tax expense $ 874 $ 1,333 $ 2,186 Deferred income tax balances are the direct effect of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the taxes are actually paid or recovered. The tax effects of temporary differences related to property and equipment, identifiable intangible assets and goodwill that gives rise to deferred tax assets (liabilities), included net within other liabilities, are as follows (in thousands): December 31, 2021 2020 Deferred tax assets: Goodwill $ 15 $ 4 Deferred tax liabilities: Property and equipment ( 4,389 ) ( 4,429 ) Identifiable intangible assets ( 30 ) ( 21 ) Total deferred tax liabilities ( 4,419 ) ( 4,450 ) Deferred tax liabilities, net $ ( 4,404 ) $ ( 4,446 ) FASB ASC Topic 740 Income Taxes (“Topic 740”) provides guidance on measurement and recognition in accounting for income tax uncertainties and provides related guidance on derecognition, classification, disclosure, interest, and penalties. As of December 31, 2021, we had no material unrecognized tax benefits (as defined in Topic 740). We do not expect to incur interest charges or penalties related to our tax positions, but if such charges or penalties are incurred, our policy is to account for interest charges and penalties as income tax expense in the Consolidated Statements of Operations. Our U.S. Federal income tax returns for years 2019 and 2020 are currently under examination by the Internal Revenue Service (“IRS”) and our Texas Margin Tax returns for report years 2018 through 2021 are currently under examination by the Texas Comptroller of Public Accounts. The Bipartisan Budget Act of 2015 provides that any tax adjustments (including any applicable penalties and interest) resulting from partnership audits will generally be determined at the partnership level for tax years beginning after December 31, 2017. To the extent possible under these rules, our General Partner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a revised information statement to each unitholder and former unitholder with respect to an audited and adjusted return. The Bipartisan Budget Act of 2015 allows a partnership to elect to apply these provisions to any return of the partnership filed for partnership taxable years beginning after the date of the enactment, November 2, 2015. We do not intend to elect to apply these provisions for any tax return filed for partnership taxable years beginning before January 1, 2018. F-16 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements (9) Long-Term Debt Our long-term debt, of which there is no current portion, consisted of the following (in thousands): December 31, 2021 2020 Senior Notes 2026, aggregate principal $ 725,000 $ 725,000 Senior Notes 2027, aggregate principal 750,000 750,000 Less: deferred financing costs, net of amortization ( 18,108 ) ( 21,805 ) Total Senior Notes, net 1,456,892 1,453,195 Revolving Credit Facility 516,342 473,810 Total long-term debt, net $ 1,973,234 $ 1,927,005 Revolving Credit Facility Credit Agreement On December 8, 2021, the Partnership amended and restated its existing credit agreement by entering into the Seventh Amended and Restated Credit Agreement (the “Credit Agreement”), by and among USA Compression Partners, LP, as borrower, the guarantors party thereto from time to time (the “Guarantors”), the lenders party thereto from time to time, and JPMorgan Chase Bank, N.A., as administrative agent and issuing bank. The Credit Agreement matures on December 8, 2026, except that if any portion of the Senior Notes 2026 are outstanding on December 31, 2025, the Credit Agreement will mature on December 31, 2025. The Credit Agreement has an aggregate commitment of $ 1.6 billion (subject to availability under our borrowing base), with a further potential increase of up to $ 200 million. The Partnership’s obligations under the Credit Agreement are guaranteed by the Guarantors, which currently consists of all of the Partnership’s existing subsidiaries. In addition, the Partnership’s obligations under the Credit Agreement are secured by: (i) substantially all of the Partnership’s assets and substantially all of the assets of the Guarantors, excluding real property and other customary exclusions; and (ii) all of the equity interests of the Partnership’s U.S. restricted subsidiaries (subject to customary exceptions). Borrowings under the Credit Agreement bear interest at a per annum interest rate equal to, at the Partnership’s option, either the Alternate Base Rate or SOFR plus the applicable margin. “Alternate Base Rate” means the greatest of (i) the prime rate, (ii) the applicable federal funds effective rate plus 0.50 % and (iii) one-month SOFR rate plus 1.00 %. The applicable margin for borrowings varies (a) in the case of SOFR loans, from 2.00 % to 2.75 % per annum and (b) in the case of Base Rate loans, from 1.00 % to 1.75 % per annum, and are determined based on a total leverage ratio pricing grid. In addition, the Borrower is required to pay commitment fees based on the daily unused amount of the Credit Agreement in an amount per annum equal to 0.375 %. Amounts borrowed and repaid under the Credit Agreement may be re-borrowed, subject to borrowing base availability. The Credit Agreement permits us to make distributions of available cash to unitholders so long as (i) no default under the facility has occurred, is continuing or would result from the distribution, (ii) immediately prior to and after giving effect to such distribution, we are in compliance with the facility’s financial covenants, and (iii) immediately prior to and after giving effect to such distribution, (a) on or before September 30, 2023, we have availability under the Credit Agreement of at least $ 250 million and (b) after September 30, 2023, we have availability under the Credit Agreement of at least $ 100 million. In addition, the Credit Agreement contains various covenants that may limit, among other things, our ability to (subject to exceptions): • grant liens; • make certain loans or investments; • incur additional indebtedness or guarantee other indebtedness; • enter into transactions with affiliates; • merge or consolidate; • sell our assets; and • make certain acquisitions. F-17 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements The Credit Agreement also contains various financial covenants, including covenants requiring us to maintain: • a minimum EBITDA to interest coverage ratio of 2.5 to 1.0, determined as of the last day of each fiscal quarter, with EBITDA and interest expense annualized for the fiscal quarter most recently ended; • a ratio of total secured indebtedness to EBITDA not greater than 3.00 to 1.00 or less than 0.00 to 1.00, determined as of the last day of each fiscal quarter, with EBITDA annualized for the fiscal quarter most recently ended; and • a maximum funded debt to EBITDA ratio, determined as of the last day of each fiscal quarter with EBITDA annualized for the fiscal quarter most recently ended, (i) 5.75 to 1.00 through the second fiscal quarter of 2022, (ii) 5.50 to 1.00 from the third quarter of 2022 through the third quarter of 2023 and (iii) 5.25 to 1.00 thereafter. In addition, the Partnership may increase the applicable ratio by 0.25 for any fiscal quarter during which a Specified Acquisition (as defined in the Credit Agreement) occurs and the following two fiscal quarters, but in no event shall the maximum ratio exceed 5.50 to 1.00 for any fiscal quarter as a result of such increase. If a default exists under the Credit Agreement, the lenders will be able to accelerate the maturity on the amount then outstanding and exercise other rights and remedies. In connection with entering into the Credit Agreement, we paid certain upfront fees and arrangement fees to the arrangers, syndication agents and senior managing agents of the Credit Agreement in the amount of $ 10.0 million during the year ended December 31, 2021. These fees were capitalized to loan costs and are amortized over the remaining term of the Credit Agreement. In connection with an amendment to our prior credit agreement, we incurred arrangement fees, consent fees and other fees in the amount of $ 3.4 million during the year ended December 31, 2020. These fees were capitalized to loan costs and are amortized over the remaining term of the credit agreement. As of December 31, 2021, we were in compliance with all of our covenants under the Credit Agreement. As of December 31, 2021, we had outstanding borrowings under the Credit Agreement of $ 516.3 million, $ 1.1 billion of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $ 261.9 million. The borrowing base consists of eligible accounts receivable, inventory and compression units. The largest component, representing 95 % of the borrowing base as of December 31, 2021, was eligible compression units. Eligible compression units consist of compressor packages that are under service contracts, leased or rented and carried in the financial statements as fixed assets. Our weighted-average interest rate in effect for all borrowings under the Credit Agreement and our prior credit agreement for the year ended December 31, 2021 was 2.98 %, and our weighted-average interest rate under the Credit Agreement as of December 31, 2021 was 2.68 %. There were no letters of credit issued as of December 31, 2021. We pay a commitment fee of 0.375 % on the unused portion of the Credit Agreement. The Credit Agreement is a “revolving credit facility” that includes a lock box arrangement, whereby remittances from customers are forwarded to a bank account controlled by the administrative agent and are applied to reduce borrowings under the facility. Amounts borrowed and repaid under the Credit Agreement may be re-borrowed. Senior Notes 2027 On March 7, 2019, the Partnership and USA Compression Finance Corp. (“Finance Corp”) co-issued the Senior Notes 2027. The Senior Notes 2027 mature on September 1, 2027 and accrue interest from at the rate of 6.875 % per year. Interest on the Senior Notes 2027 is payable semi-annually in arrears on each of March 1 and September 1. At any time prior to September 1, 2022, we may redeem up to 35 % of the aggregate principal amount of the Senior Notes 2027 at a redemption price equal to 106.875 % of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, in an amount not greater than the net proceeds from one or more equity offerings, provided that at least 65 % of the aggregate principal amount of the Senior Notes 2027 remains outstanding immediately after the occurrence of such redemption (excluding Senior Notes 2027 held by us and our subsidiaries) and redemption occurs within 180 days of the date of the closing of such equity offering. Prior to September 1, 2022, we may redeem all or a part of the Senior Notes 2027 at a redemption price equal to the sum of (i) the principal amount thereof, plus (ii) a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date. F-18 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements On or after September 1, 2022, we may redeem all or a part of the Senior Notes 2027 at redemption prices (expressed as percentages of the principal amount) set forth below, plus accrued and unpaid interest, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on September 1 of the years indicated below: Year Percentages 2022 105.156 % 2023 103.438 % 2024 101.719 % 2025 and thereafter 100.000 % If we experience a change of control followed by a ratings decline, unless we have previously exercised or concurrently exercise our right to redeem the Senior Notes 2027 (as described above), we may be required to offer to repurchase the Senior Notes 2027 at a purchase price equal to 101 % of the principal amount repurchased, plus accrued and unpaid interest, if any, to the repurchase date. The indenture governing the Senior Notes 2027 (the “2027 Indenture”) contains certain financial ratios that we must comply with in order to make certain restricted payments as described in the 2027 Indenture. As of December 31, 2021, we were in compliance with such financial covenants under the 2027 Indenture. In connection with issuing the Senior Notes 2027, we incurred certain issuance costs in the amount of $ 13.3 million during the year ended December 31, 2019, which is amortized over the term of the Senior Notes 2027. The Senior Notes 2027 are fully and unconditionally guaranteed (the “2027 Guarantees”), jointly and severally, on a senior unsecured basis by all of our existing subsidiaries (other than Finance Corp), and will be fully and unconditionally guaranteed, jointly and severally, by each of our future restricted subsidiaries that either borrows under, or guarantees, the Credit Agreement or guarantees certain of our other indebtedness (collectively, the “Guarantors”). The Senior Notes 2027 and the 2027 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’, Finance Corp’s, and our existing and future senior indebtedness and senior to the Guarantors’, Finance Corp’s, and our future subordinated indebtedness, if any. The Senior Notes 2027 and the 2027 Guarantees are effectively subordinated in right of payment to all of the Guarantors’, Finance Corp’s, and our existing and future secured debt, including debt under the Credit Agreement and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of our subsidiaries that do not guarantee the Senior Notes 2027. On December 18, 2019, the Partnership closed an exchange offer whereby holders of the Senior Notes 2027 exchanged all of the Senior Notes 2027 for an equivalent amount of senior notes (“Exchange Notes 2027”) registered under the Securities Act. The Exchange Notes 2027 are substantially identical to the Senior Notes 2027, except that the Exchange Notes 2027 have been registered with the SEC and do not contain the transfer restrictions, restrictive legends, registration rights or additional interest provisions of the Senior Notes 2027. Senior Notes 2026 On March 23, 2018, the Partnership and Finance Corp co-issued the Senior Notes 2026. The Senior Notes 2026 mature on April 1, 2026 and accrue interest from March 23, 2018 at the rate of 6.875 % per year. Interest on the Senior Notes 2026 is payable semi-annually in arrears on each of April 1 and October 1. We may redeem all or a part of the Senior Notes 2026 at redemption prices (expressed as percentages of the principal amount) set forth below, plus accrued and unpaid interest, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 of the years indicated below: Year Percentages 2021 105.156 % 2022 103.438 % 2023 101.719 % 2024 and thereafter 100.000 % If we experience a change of control followed by a ratings decline, unless we have previously exercised or concurrently exercise our right to redeem the Senior Notes 2026 (as described above), we may be required to offer to repurchase the Senior F-19 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements Notes 2026 at a purchase price equal to 101 % of the principal amount repurchased, plus accrued and unpaid interest, if any, to the repurchase date. The indenture governing the Senior Notes 2026 (the “2026 Indenture”) contains certain financial ratios that we must comply with in order to make certain restricted payments as described in the 2026 Indenture. As of December 31, 2021, we were in compliance with such financial covenants under the 2026 Indenture. The Senior Notes 2026 are fully and unconditionally guaranteed (the “2026 Guarantees”), jointly and severally, on a senior unsecured basis by the Guarantors. The Senior Notes 2026 and the 2026 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’, Finance Corp’s, and our existing and future senior indebtedness and senior to the Guarantors’, Finance Corp’s, and our future subordinated indebtedness, if any. The Senior Notes 2026 and the 2026 Guarantees are effectively subordinated in right of payment to all of the Guarantors, Finance Corp’s, and our existing and future secured debt, including debt under the Credit Agreement and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of our subsidiaries that do not guarantee the Senior Notes 2026. On January 14, 2019, the Partnership closed an exchange offer whereby holders of the Senior Notes 2026 exchanged all of the Senior Notes 2026 for an equivalent amount of senior notes (“Exchange Notes 2026”) registered under the Securities Act. The Exchange Notes 2026 are substantially identical to the Senior Notes 2026, except that the Exchange Notes 2026 have been registered with the SEC and do not contain the transfer restrictions, restrictive legends, registration rights or additional interest provisions of the Senior Notes 2026. We have no assets or operations independent of our subsidiaries, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. Each of the Guarantors is 100 % owned by us. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended (“Securities Act”). Subsidiary Guarantors The Partnership may from time to time file a Registration Statement on Form S-3 with the SEC to register the issuance and sale of, among other securities, debt securities, which may be co-issued by Finance Corp (together with the Partnership, the “Issuers”) and fully and unconditionally guaranteed on a joint and several basis by the Partnership’s operating subsidiaries for the benefit of each holder and the trustee. Such guarantees are expected to be subject to release, subject to certain limitations, as follows (i) upon the sale, exchange or transfer, by way of a merger or otherwise, to any person that is not our affiliate, of all of our direct or indirect limited partnership or other equity interest in such subsidiary guarantor; or (ii) upon delivery by an Issuer of a written notice to the trustee of the release or discharge of all guarantees by such subsidiary guarantor of any debt of the Issuers other than obligations arising under the indenture governing such debt and any debt securities issued under such indenture, except a discharge or release by or as a result of payment under such guarantees. Maturities of long-term debt for each of the five succeeding years are as follows (in thousands): Year Ending December 31, 2022 $ — 2023 — 2024 — 2025 — 2026 1,241,342 Thereafter 750,000 (10) Preferred Units Preferred Unit and Warrant Private Placement On April 2, 2018, we completed a private placement of $ 500 million in the aggregate of (i) newly authorized and established Preferred Units and (ii) warrants to purchase common units (the “Warrants”) pursuant to a Series A Preferred Unit and Warrant Purchase Agreement dated January 15, 2018, with certain investment funds managed or advised by EIG Global Energy Partners (collectively, the “Preferred Unitholders”). We issued 500,000 Preferred Units with a face value of $ 1,000 per Preferred Unit and issued two tranches of Warrants to the Preferred Unitholders, which included Warrants to purchase F-20 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements 5,000,000 common units with a strike price of $ 17.03 per unit and 10,000,000 common units with a strike price of $ 19.59 per unit. On November 13, 2018, the Partnership filed a Registration Statement on Form S-3 to register 41,202,553 common units that are potentially issuable upon conversion of the Preferred Units and exercise of the Warrants. The Preferred Units rank senior to the common units with respect to distributions and rights upon liquidation. The Preferred Unitholders are entitled to receive cumulative quarterly cash distributions equal to $ 24.375 per Preferred Unit. As of December 31, 2021 and 2020, 500,000 Preferred Units were issued and outstanding. We have declared and paid quarterly cash distributions per unit to our Preferred Unitholders of record as follows: Payment date Distribution per Preferred Unit February 8, 2019 $ 24.375 May 10, 2019 24.375 August 9, 2019 24.375 November 8, 2019 24.375 Total 2019 distributions $ 97.500 February 7, 2020 $ 24.375 May 8, 2020 24.375 August 10, 2020 24.375 November 6, 2020 24.375 Total 2020 distributions $ 97.500 February 5, 2021 $ 24.375 May 7, 2021 24.375 August 6, 2021 24.375 November 5, 2021 24.375 Total 2021 distributions $ 97.500 Announced Quarterly Distribution On January 13, 2022, we declared a cash distribution of $ 24.375 per unit on our Preferred Units. The distribution was paid on February 4, 2022 to unitholders of record as of the close of business on January 24, 2022. Redemption and Conversion Features The Preferred Units are convertible, at the option of the holder, into common units in accordance with the terms of our Second Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”) as follows: one third on or after April 2, 2021, two thirds on or after April 2, 2022, and 100% are convertible on or after April 2, 2023. The conversion rate for the Preferred Units is the quotient of (a) the sum of (i) $ 1,000 , plus (ii) any unpaid cash distributions on the applicable Preferred Unit, divided by (b) $ 20.0115 for each Preferred Unit. The Preferred Unitholders are entitled to vote on an as-converted basis with the common unitholders and (as proportionately adjusted for unit splits, unit distributions and similar transactions) will have certain other class voting rights with respect to any amendment to the Partnership Agreement that would adversely affect any rights, preferences or privileges of the Preferred Units. In addition, upon certain events involving a change of control the Preferred Unitholders may elect, among other potential elections, to convert their Preferred Units to common units at the then change of control conversion rate. On or after April 2, 2023, we have the option to redeem all or any portion of the Preferred Units then outstanding, subject to certain minimum redemption threshold amounts, for a redemption price set forth in the Partnership Agreement. On or after April 2, 2028, each Preferred Unitholder will have the right to require us to redeem all or a portion of their Preferred Units, subject to certain minimum redemption threshold amounts, for a redemption price set forth in the Partnership Agreement, which we may elect to pay up to 50 % in common units, subject to certain additional limits. The Preferred Units are presented as F-21 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements temporary equity in the mezzanine section of the consolidated balance sheets because the redemption provisions on or after April 2, 2028 are outside the Partnership’s control. The Preferred Units were recorded at their issuance date fair value, net of issuance cost. Net income allocations increase the carrying value and declared distributions decrease the carrying value of the Preferred Units. As the Preferred Units are not currently redeemable and it is not probable that they will become redeemable, adjustment to the initial carrying value is not necessary and would only be required if it becomes probable that the Preferred Units would become redeemable. Changes in the Preferred Units balance are summarized below (in thousands): Preferred Units Balance at December 31, 2018 $ 477,309 Net income allocated to Preferred Units 48,750 Cash distributions on Preferred Units ( 48,750 ) Balance at December 31, 2019 477,309 Net income allocated to Preferred Units 48,750 Cash distributions on Preferred Units ( 48,750 ) Balance at December 31, 2020 477,309 Net income allocated to Preferred Units 48,750 Cash distributions on Preferred Units ( 48,750 ) Balance at December 31, 2021 $ 477,309 Refer to Note 13 for information about the rights EIG Veteran Equity Aggregator, L.P. (along with its affiliated funds, “EIG”) has to designate one of the members of the Board. (11) Partners’ Capital Common and Class B Units The change in common units and Class B Units outstanding were as follows: Units outstanding Common Class B Number of units outstanding, December 31, 2018 89,983,790 6,397,965 Vesting of phantom units 189,637 — Issuance of common units under the DRIP 60,584 — Conversion of Class B Units to common units 6,397,965 ( 6,397,965 ) Number of units outstanding, December 31, 2019 96,631,976 — Vesting of phantom units 141,652 — Issuance of common units under the DRIP 188,695 — Number of units outstanding, December 31, 2020 96,962,323 — Vesting of phantom units 263,985 — Issuance of common units under the DRIP 118,399 — Number of units outstanding, December 31, 2021 97,344,707 — As of December 31, 2021, Energy Transfer LP held 46,056,228 common units, including 8,000,000 common units held by the General Partner and controlled by Energy Transfer LP. The limited partners holding our common units have the following rights, among others: • right to receive distributions of our available cash within 45 days after the end of each quarter, so long as we have paid the required distributions on the Preferred Units for such quarter; • right to transfer limited partner unit ownership to substitute limited partners; • right to approve certain amendments of the Partnership Agreement; F-22 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements • right to electronic access of an annual report, containing audited financial statements and a report on those financial statements by our independent public accountants within 90 days after the close of the fiscal year end; and • right to receive information reasonably required for tax reporting purposes within 90 days after the close of the calendar year. Class B Units Conversion On July 30, 2019, 6,397,965 Class B Units representing limited partner interests in us (“Class B Units”) automatically converted into common units on a one-for-one basis, resulting in the issuance of 6,397,965 common units to Energy Transfer. Following the conversion, there are no longer Class B Units outstanding. Cash Distributions We have declared and paid quarterly distributions per unit to our limited partner unitholders of record, including holders of our common and phantom units, as follows (dollars in millions, except distribution per unit): Payment Date Distribution per Limited Partner Unit Amount Paid to Common Unitholders Amount Paid to Phantom Unitholders Total Distribution February 8, 2019 $ 0.525 $ 47.2 $ 0.7 $ 47.9 May 10, 2019 0.525 47.3 0.6 47.9 August 9, 2019 0.525 47.4 0.6 48.0 November 8, 2019 0.525 50.7 0.6 51.3 Total 2019 distributions $ 2.10 $ 192.6 $ 2.5 $ 195.1 February 7, 2020 $ 0.525 $ 50.7 $ 0.9 $ 51.6 May 8, 2020 0.525 50.8 0.9 51.7 August 10, 2020 0.525 50.9 0.8 51.7 November 6, 2020 0.525 50.9 0.7 51.6 Total 2020 distributions $ 2.10 $ 203.3 $ 3.3 $ 206.6 February 5, 2021 $ 0.525 $ 50.9 $ 1.1 $ 52.0 May 7, 2021 0.525 50.9 1.1 52.0 August 6, 2021 0.525 51.0 1.1 52.1 November 5, 2021 0.525 51.0 1.0 52.0 Total 2021 distributions $ 2.10 $ 203.8 $ 4.3 $ 208.1 Announced Quarterly Distribution On January 13, 2022, we announced a cash distribution of $ 0.525 per unit on our common units. The distribution was paid on February 4, 2022 to unitholders of record as of the close of business on January 24, 2022. DRIP During the years ended December 31, 2021, 2020 and 2019, distributions of $ 1.8 million, $ 1.9 million and $ 1.0 million, respectively, were reinvested under the DRIP resulting in the issuance of 118,399 , 188,695 and 60,584 common units, respectively. On August 5, 2020, we filed a registration statement on Form S-3 for the issuance of up to 5,000,000 units under the DRIP. F-23 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements Warrants As of December 31, 2021 and December 31, 2020, we had two tranches of warrants outstanding, which includes warrants to purchase (i) 5,000,000 common units with a strike price of $ 17.03 per common unit and (ii) 10,000,000 common units with a strike price of $ 19.59 per common unit. The Warrants may be exercised by the holders at any time before April 2, 2028. The Warrants are presented within the equity section of the Consolidated Balance Sheets in accordance with GAAP as they are indexed to the Partnership’s own stock and require physical settlement or net share settlement. The Warrants were valued at issuance using the Black-Scholes-Merton model. Loss Per Unit The computations of loss per unit are based on the weighted average number of participating securities outstanding during the period. Basic loss per unit is determined by dividing net income (loss) allocated to participating securities after deducting the amount distributed on Preferred Units, by the weighted average number of participating securities outstanding during the period. Net loss attributable to unitholders is allocated to participating securities based on their respective shares of the distributed and undistributed earnings for the period. To the extent cash distributions exceed net loss attributable to unitholders for the period, the excess distributions are allocated to all participating securities outstanding based on their respective ownership percentages. Diluted earnings per unit are computed using the treasury stock method, which considers the potential issuance of limited partner units associated with our long-term incentive plan and warrants. The classes of participating securities include common units, Class B Units prior to July 30, 2019, and certain equity-based compensation awards. Unvested phantom units and unexercised warrants are not included in basic earnings per unit, as they are not considered to be participating securities, but are included in the calculation of diluted earnings per unit to the extent that they are dilutive, and in the case of warrants to the extent they are considered “in the money”. For the years ended December 31, 2021, 2020 and 2019, approximately 829,000 , 634,000 and 290,000 incremental unvested phantom units, respectively, were excluded from the calculation of diluted earnings per unit because the impact was anti-dilutive. Our outstanding warrants are not applicable to the computation as they are not considered “in the money” for the years ended December 31, 2021, 2020 or 2019. (12) Revenue Recognition The following table disaggregates our revenue by type of service (in thousands): Year Ended December 31, 2021 2020 2019 Contract operations revenue $ 621,449 $ 656,616 $ 681,472 Retail parts and services revenue 11,196 11,067 16,893 Total revenues $ 632,645 $ 667,683 $ 698,365 The following table disaggregates our revenue by timing of provision of services or transfer of goods (in thousands): Year Ended December 31, 2021 2020 2019 Services provided over time: Primary term $ 419,307 $ 458,479 $ 434,705 Month-to-month 202,142 198,137 246,767 Total services provided over time 621,449 656,616 681,472 Services provided or goods transferred at a point in time 11,196 11,067 16,893 Total revenues $ 632,645 $ 667,683 $ 698,365 Contract operations revenue Revenue from contracted compression, station, gas treating and maintenance services is recognized ratably under our fixed-fee contracts over the term of the contract as services are provided to our customers. Initial contract terms typically range from six months to five years , however we usually continue to provide compression services at a specific location beyond the initial contract term, either through contract renewal or on a month-to-month or longer basis. We primarily enter into fixed-fee F-24 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements contracts whereby our customers are required to pay our monthly fee even during periods of limited or disrupted throughput. Services are generally billed monthly, one month in advance of the commencement of the service month, except for certain customers who are billed at the beginning of the service month, and payment is generally due 30 days after receipt of our invoice. Amounts invoiced in advance are recorded as deferred revenue until earned, at which time they are recognized as revenue. The amount of consideration we receive and revenue we recognize is based upon the fixed fee rate stated in each service contract. Variable consideration exists in select contracts when billing rates vary based on actual equipment availability or volume of total installed horsepower. Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenues to each performance obligation based on its relative standalone service fee. We generally determine standalone service fees based on the service fees charged to customers or use expected cost plus margin. The majority of our service performance obligations are satisfied over time as services are rendered at selected customer locations on a monthly basis and based upon specific performance criteria identified in the applicable contract. The monthly service for each location is substantially the same service month to month and is promised consecutively over the service contract term. We measure progress and performance of the service consistently using a straight-line, time-based method as each month passes, because our performance obligations are satisfied evenly over the contract term as the customer simultaneously receives and consumes the benefits provided by our service. If variable consideration exists, it is allocated to the distinct monthly service within the series to which such variable consideration relates. We have elected to apply the invoicing practical expedient to recognize revenue for such variable consideration, as the invoice corresponds directly to the value transferred to the customer based on our performance completed to date. There are typically no material obligations for returns or refunds. Our standard contracts do not usually include material non-cash consideration. Retail parts and services revenue Retail parts and services revenue is earned primarily on freight and crane charges that are directly reimbursable by our customers and maintenance work on units at our customers’ locations that are outside the scope of our core maintenance activities. Revenue from retail parts and services is recognized at the point in time the part is transferred or service is provided and control is transferred to the customer. At such time, the customer has the ability to direct the use of the benefits of such part or service after we have performed our services. We bill upon completion of the service or transfer of the parts, and payment is generally due 30 days after receipt of our invoice. The amount of consideration we receive and revenue we recognize is based upon the invoice amount. There are typically no material obligations for returns, refunds, or warranties. Our standard contracts do not usually include material variable or non-cash consideration. Contract Assets We record contract assets when we have completed performance under a contract but our right to consideration is not yet unconditional. We had no contract assets as of December 31, 2021 or 2020. Deferred Revenue We record deferred revenue when cash payments are received or due in advance of our performance. Components of deferred revenue were as follows: December 31, Balance sheet location 2021 2020 Current (1) Deferred revenue $ 51,216 $ 47,202 Noncurrent Other liabilities 4,823 8,200 Total $ 56,039 $ 55,402 ________________________ (1) We recognized $ 43.2 million of revenue during the year ended December 31, 2021 related to our deferred revenue balance as of December 31, 2020. F-25 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements Performance Obligations As of December 31, 2021, the aggregate amount of transaction price allocated to unsatisfied performance obligations related to our contract operations revenue is $ 438.6 million. We expect to recognize these remaining performance obligations as follows (in thousands): 2022 2023 2024 2025 Thereafter Total Remaining performance obligations $ 277,919 $ 109,206 $ 39,375 $ 10,089 $ 2,026 $ 438,615 (13) Transactions with Related Parties We provide compression services to entities affiliated with Energy Transfer, which as of December 31, 2021, owned approximately 47 % of our limited partner interests and 100 % of the General Partner. The following table summarizes the revenues from Energy Transfer on our consolidated statement of operations (in thousands): Year Ended December 31, 2021 2020 2019 Related party revenues $ 11,967 $ 12,372 $ 19,967 We had approximately $ 18,000 and $ 120,000 within related party receivables on our consolidated balance sheets as of December 31, 2021 and December 31, 2020, respectively, from such affiliated Energy Transfer entities. Additionally, the Partnership had a $ 44.9 million related party receivable from Energy Transfer as of December 31, 2021 and December 31, 2020 related to indemnification for sales tax contingencies. See Note 16 for more information related to such sales tax contingencies. Pursuant to that certain Board Representation Agreement entered into by us, the General Partner, Energy Transfer LP and EIG in connection with our private placement of Preferred Units and Warrants to EIG, EIG Management Company, LLC has the right to designate one of the members of the Board for so long as the holders of the Preferred Units hold more than 5 % of the Partnership’s outstanding common units in the aggregate (taking into account the common units that would be issuable upon conversion of the Preferred Units and exercise of the Warrants). (14) Unit-Based Compensation Long-Term Incentive Plan In January 2013, the board of directors of the General Partner (the “Board”) adopted the USA Compression Partners, LP 2013 Long-Term Incentive Plan (as amended, the “LTIP”), which is available for certain employees, consultants and directors of the General Partner and any of its affiliates who perform services for us. The LTIP provides for awards of unit options, unit appreciation rights, restricted units, phantom units, DERs, unit awards, profits interest units and other unit-based awards. Under the LTIP, the maximum number of common units available for issuance is 10,000,000 and the term of the LTIP is until November 1, 2028. Awards that are forfeited, canceled, paid or otherwise terminate or expire without the actual delivery of common units will be available for delivery pursuant to other awards. The LTIP is administered by the Board or a committee thereof. The General Partner’s executive officers, certain of its employees and certain of its independent directors were granted these awards to incentivize them to help drive our future success and to share in the economic benefits of that success. All employees with phantom units have a portion of their award settled in cash and a portion settled in common units upon vesting, unless otherwise approved by the Board. The amount that can be settled in cash is in excess of the employee’s minimum statutory tax-withholding rate. ASC Topic 718, Compensation – Stock Compensation , requires the entire amount of an award with such features to be accounted for as a liability. Under the liability method of accounting for unit-based compensation, we re-measure the fair value of the award at each financial statement date until the award vests or is forfeited. The fair value is measured using the market price of the Partnership’s common units. During the requisite service period (the vesting period of the awards), compensation cost is recognized using the proportionate amount of the award’s fair value that has been earned through service to date. Phantom units granted to independent directors do not have a cash settlement option and as such we account for these awards as equity. Each phantom unit is granted in tandem with a corresponding DER, which entitles the recipient to receive an amount in cash on a quarterly basis equal to the product of (i) the number of the recipient’s outstanding, unvested phantom units on the record date for such quarter and (ii) the quarterly distribution declared by the Board for such quarter with respect to the Partnership’s common units. F-26 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements During the years ended December 31, 2021, 2020 and 2019, an aggregate of 638,903 , 741,963 and 717,869 , respectively, phantom units (including the corresponding DERs) were granted under the LTIP to the General Partner’s executive officers and certain of its employees and independent directors. The phantom units (including the corresponding DERs) awarded are subject to restrictions on transferability, customary forfeiture provisions and time vesting provisions. Phantom unit awards granted after July 30, 2018 vest incrementally, with 60 % of the phantom units vesting on December 5 of the third year following the grant and the remaining 40 % vesting on December 5 of the fifth year following the grant. Phantom unit awards that were granted to employees of USAC Management prior to July 30, 2018 vested evenly over a three-year service period. Phantom units granted on or after July 30, 2018 vest in full upon a change in control. Award recipients do not have all the rights of a unitholder in the Partnership with respect to the phantom units until the units have vested. As of December 31, 2021 and 2020, our total unit-based compensation liability was $ 13.3 million and $ 9.2 million, respectively. During the years ended December 31, 2021, 2020 and 2019, we recognized $ 15.5 million, $ 8.4 million and $ 10.8 million of compensation expense associated with these awards, respectively, recorded in selling, general and administrative expense. During the years ended December 31, 2021, 2020 and 2019, amounts paid related to the cash settlement of vested awards under the LTIP were $ 3.2 million, $ 1.1 million and $ 1.7 million, respectively. The total fair value and intrinsic value of the phantom units vested under the LTIP was $ 4.0 million, $ 1.7 million and $ 4.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. The following table summarizes information regarding phantom unit awards for the periods presented: Number of Units Weighted-Average Grant Date Fair Value per Unit Phantom units outstanding at December 31, 2018 1,431,064 $ 14.98 Granted 717,869 15.88 Vested ( 301,329 ) 13.06 Forfeited ( 45,620 ) 16.78 Phantom units outstanding at December 31, 2019 1,801,984 $ 15.09 Granted 741,963 12.55 Vested ( 223,658 ) 17.27 Forfeited ( 182,332 ) 15.36 Phantom units outstanding at December 31, 2020 2,137,957 $ 14.88 Granted 638,903 14.92 Vested ( 475,831 ) 15.13 Forfeited ( 71,261 ) 14.50 Phantom units outstanding at December 31, 2021 2,229,768 $ 13.57 The unrecognized compensation cost associated with phantom unit awards was an aggregate $ 25.2 million as of December 31, 2021. We expect to recognize the unrecognized compensation cost for these awards on a weighted-average basis over a period of 2.7 years. (15) Employee Benefit Plans A 401(k) plan is available to all of our employees. The plan permits employees to contribute up to 20 % of their salary, up to the statutory limits, which was $ 19,500 for 2021. The plan provides for discretionary matching contributions by us on an annual basis. Aggregate matching contributions made to employees’ 401(k) plans were $ 3.5 million, $ 3.4 million and $ 3.4 million for the years ended December 31, 2021, 2020 and 2019, respectively. (16) Commitments and Contingencies (a) Major Customers We did not have revenue from any single customer representing 10% or more of total revenue for the years ended December 31, 2021, 2020 or 2019. F-27 Table of Contents USA COMPRESSION PARTNERS, LP Notes to Consolidated Financial Statements As of December 31, 2021, one customer accounted for 14 % of our trade account receivables, net balance. As of December 31, 2020, two customers accounted for 13 % and 11 % of our trade accounts receivables, net balance, respectively. (b) Litigation From time to time, we and our subsidiaries may be involved in various claims and litigation arising in the ordinary course of business. In management’s opinion, the resolution of such matters is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. (c) Equipment Purchase Commitments Our future capital commitments are comprised of binding commitments under purchase orders for new compression units ordered but not received. The commitments as of December 31, 2021 were $ 19.3 million, all of which is expected to be settled within the next twelve months. (d) Sales Tax Contingencies Our compliance with state and local sales tax regulations is subject to audit by various taxing authorities. Certain taxing authorities have either claimed or issued an assessment that specific operational processes, which we and others in our industry regularly conduct, result in transactions that are subject to state sales taxes. We and others in our industry have disputed these claims and assessments based on either existing tax statutes or published guidance by the taxing authorities. We are currently protesting certain assessments made by the Oklahoma Tax Commission (“OTC”). We believe it is reasonably possible that we could incur losses related to this assessment depending on whether the administrative law judge assigned by the OTC accepts our position that the transactions are not taxable and we ultimately lose any and all subsequent legal challenges to such determination. We estimate that the range of losses we could incur is from $ 0 to approximately $ 19.5 million, including penalty and interest. As of December 31, 2021 and 2020, we have recorded a $ 44.9 million accrued liability and $ 44.9 million related party receivable from Energy Transfer related to open audits with the Office of the Texas Comptroller of Public Accounts (the “Comptroller”), wherein the Comptroller has challenged the applicability of the manufacturing exemption. (e) Environmental The Partnership’s operations are subject to federal, state and local laws and rules and regulations regarding water quality, hazardous and solid waste management, air quality control and other environmental matters. These laws, rules and regulations require the Partnership to conduct its operations in a specified manner and to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections and other approvals. Failure to comply with applicable environmental laws, rules and regulations may expose the Partnership to significant fines, penalties and/or interruptions in operations. The Partnership’s environmental policies and procedures are designed to achieve compliance with such applicable laws and regulations. These evolving laws and regulations and claims for damages to property, employees, other persons and the environment resulting from current or past operations may result in significant expenditures and liabilities in the future.
