The USA Compression Predecessor is consideredthe predecessor of the Partnership because Energy Transfer Equity LP (“ETE”), through its wholly owned subsidiary Energy Transfer Partners, L.L.C., (“ETPLLC”) controlled the USA Compression Predecessor prior to the transactions described below and obtained control of the Partnership through its acquisition ofUSA Compression GP, LLC, the general partner of the Partnership (the “General Partner”).The closing of the Transactions occurred on April 2, 2018 (the “Transactions Date”) and has been reflected in the consolidated financial statements of thePartnership.In October 2018, ETE and Energy Transfer Partners, L.P. (“ETP”) completed the merger of ETP with a wholly owned subsidiary of ETE in a unit-for-unitexchange (the “ETE Merger”). Following the closing of the ETE Merger, ETE changed its1Table of Contentsname to “Energy Transfer LP” (“ET LP”) and ETP changed its name to “Energy Transfer Operating, L.P.” (“ETO”). Upon the closing of the ETE Merger, ETEcontributed to ETO 100% of the limited liability company interests in the General Partner. References herein to “ETO” refer to ETP for periods prior to the ETEMerger and ETO following the ETE Merger, and references to “ET LP” refer to ETE for periods prior to the ETE Merger and ET LP following the ETE Merger.All references in this report to the USA Compression Predecessor, as well as the terms “our,” “we,” “us” and “its” refer to the USA CompressionPredecessor when used in a historical context or in reference to the periods prior to the Transactions Date, unless the context otherwise requires or whereotherwise indicated. All references in this section to the Partnership, as well as the terms “our,” “we,” “us” and “its” refer to USA Compression Partners, LP,together with its consolidated subsidiaries, including the USA Compression Predecessor, when used in the present or future tense and for periods subsequent tothe Transactions Date, unless the context otherwise requires or where otherwise indicated.OverviewWe are a growth-oriented Delaware limited partnership, and we believe that we are one of the largest independent providers of natural gas compressionservices in the United States (“U.S.”) in terms of total compression fleet horsepower. USA Compression Partners, LP has been providing compression servicessince 1998 and completed its initial public offering in January 2013. The USA Compression Predecessor has been providing compression services since 1997 andwas a wholly owned indirect subsidiary of ETO prior to the Transactions Date. As of December 31, 2019, we had 3,682,968 horsepower in our fleet and 56,500horsepower on order for expected delivery during 2020. We provide compression services to our customers primarily in connection with infrastructureapplications, including both allowing for the processing and transportation of natural gas through the domestic pipeline system and enhancing crude oil productionthrough artificial lift processes. As such, our compression services play a critical role in the production, processing and transportation of both natural gas and crudeoil.We 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. Demand for our services is driven by the domestic productionof natural gas and crude oil; as such, we have focused our activities in areas with attractive natural gas and crude oil production growth, which are generally foundin these shale and unconventional resource plays. According to studies promulgated by the U.S. Energy Information Administration (“EIA”), the production andtransportation volumes of these shale plays, in aggregate, are expected to increase over the long term due to the comparatively attractive economic returns versusreturns achieved in many conventional basins. Furthermore, the changes in production volumes and pressures of shale plays over time require a wider range ofcompression services than in conventional basins. We believe we are well-positioned to meet these changing operating conditions due to the flexibility of ourcompression units. While our business focuses largely on compression services serving infrastructure applications, including centralized natural gas gatheringsystems and processing facilities, which utilize large horsepower compression units, typically in shale plays, we also provide compression services in moremature conventional basins, including gas lift applications on crude oil wells targeted by horizontal drilling techniques. Gas lift, a process by which natural gas isinjected into the production tubing of an existing producing well, in order to reduce the hydrostatic pressure and allow the oil to flow at a higher rate, and otherartificial lift technologies are critical to the enhancement of oil production from horizontal wells operating in tight shale plays.We operate a modern fleet of compression units, with an average age of approximately six years. We acquire our compression units from third-partyfabricators who build the units to our specifications, utilizing specific components from original equipment manufacturers and assembling the units in a mannerthat provides us the ability to meet certain operating condition thresholds. Our standard new-build compression units are generally configured for multiplecompression stages allowing us to operate our units across a broad range of operating conditions. The design flexibility of our units, particularly in midstreamapplications, allows us to enter into longer-term contracts and reduces the redeployment risk of our horsepower in the field. Our modern and standardized fleet,decentralized field level operating structure and technical proficiency in predictive and preventive maintenance and overhaul operations have enabled us to achieveaverage service run times consistently at or above the levels required by our customers and maintain high overall utilization rates for our fleet.As part of our services, we engineer, design, operate, service and repair our compression units and maintain related support inventory and equipment. Thecompression units in our modern fleet are designed to be easily adaptable to fit our customers’ changing compression requirements. Focusing on the needs of ourcustomers and providing them with reliable and flexible compression services in geographic areas of attractive growth helps us to generate stable cash flows forour unitholders.We provide compression services to our customers under fixed-fee contracts with initial contract terms typically between six months and five years,depending on the application and location of the compression unit. We typically continue to provide compression services at a specific location beyond the initialcontract term, either through contract renewal or on a month-to-month or longer basis. We primarily enter into take-or-pay contracts whereby our customers arerequired to pay our monthly fee2Table of Contentseven during periods of limited or disrupted throughput, which enhances the stability and predictability of our cash flows. We are not directly exposed tocommodity price risk because we do not take title to the natural gas or crude oil involved in our services and because the natural gas used as fuel by ourcompression units is supplied by our customers without cost to us.We provide compression services to major oil companies and independent producers, processors, gatherers and transporters of natural gas and crudeoil. Regardless of the application for which our services are provided, our customers rely upon the availability of the equipment used to provide compressionservices and our expertise to maximize the throughput of product, reduce fuel costs and minimize emissions. While we significantly expanded our geographicfootprint with our acquisition of the USA Compression Predecessor from ETO (the “CDM Acquisition”), our customers may have compression demands in areasof the U.S. in conjunction with their field development projects where we are not currently operating. We continually consider further expansion of our geographicareas of operation in the U.S. based upon the level of customer demand. Our modern, flexible fleet of compression units, which have been designed to be rapidlydeployed and redeployed throughout the country, provides us with opportunities to expand into other areas with both new and existing customers. We also own and operate a fleet of equipment used to provide natural gas treating services, such as carbon dioxide and hydrogen sulfide removal, natural gascooling and dehydration, to natural gas producers and midstream companies.Our assets and operations are organized into a single reportable segment and are all located and conducted in the U.S. See our consolidated financialstatements, and the notes thereto, in Part II, Item 8 “Financial Statements and Supplementary Data” for financial information on our operations and assets; suchinformation is incorporated herein by reference.Recent Developments2027 Senior Notes Issuance and ExchangeOn March 7, 2019, the Partnership and its wholly owned finance subsidiary, USA Compression Finance Corp.

As part of our services, we engineer, design, operate, service and repair our fleet ofcompression units and maintain related support inventory and equipment. In certain instances, we also engineer, design, install, operate, service and repair certainancillary equipment used in conjunction with our compression services. We have consistently provided average service run times at or above the levels required byour customers. In general, our team of field service technicians services only our compression fleet and ancillary equipment. In limited circumstances and forestablished customers, we will agree to service third-party owned equipment. We do not own any compression fabrication facilities.Our Compression FleetThe fleet of compression units that we own and use to provide compression services consists of specially engineered compression units that utilizestandardized components, principally engines manufactured by Caterpillar, Inc. and compressor frames and cylinders manufactured by Ariel Corporation. Ourunits can be rapidly and cost effectively modified for specific customer applications. As of December 31, 2019, the average age of our compression units wasapproximately six years. Our modern, standardized compression unit fleet is powered primarily by the Caterpillar 3400, 3500 and 3600 engine classes, which rangefrom 401 to 5,000 horsepower per unit. These larger horsepower units, which we define as 400 horsepower per unit or greater, represented 86.2% of our total fleethorsepower (including compression units on order) as of December 31, 2019. In addition, a portion of our fleet consists of smaller horsepower units ranging from40 horsepower to 399 horsepower that are primarily used in gas lift applications. We believe the average age and overall composition of our compressor fleet resultin fewer mechanical failures, lower fuel usage, and reduced environmental emissions.The following table provides a summary of our compression units by horsepower as of December 31, 2019:Unit Horsepower FleetHorsepower Number ofUnits Horsepoweron Order (1) Number ofUnitson Order TotalHorsepower Number ofUnits Percent ofTotalHorsepower Percent ofTotalUnitsSmall horsepower <400 516,674 3,031 — — 516,674 3,031 13.8% 55.3%Large horsepower >400 and <1,000 426,384 730 9,000 15 435,384 745 11.6% 13.6%>1,000 2,739,910 1,690 47,500 19 2,787,410 1,709 74.6% 31.1%Total large horsepower 3,166,294 2,420 56,500 34 3,222,794 2,454 86.2% 44.7%Total horsepower 3,682,968 5,451 56,500 34 3,739,468 5,485 100.0% 100.0%________________________________(1)As of December 31, 2019, we had 56,500 large horsepower on order for delivery during 2020.5Table of ContentsThe following table sets forth certain information regarding our compression fleet as of the dates and for the periods indicated and excludes certain gastreating assets for which horsepower is not a relevant metric: Year Ended December 31, PercentOperating Data: 2019 2018 ChangeFleet horsepower (at period end) (1) 3,682,968 3,597,097 2.4 %Total available horsepower (at period end) (2) 3,709,468 3,675,447 0.9 %Revenue generating horsepower (at period end) (3) 3,310,024 3,262,470 1.5 %Average revenue generating horsepower (4) 3,279,374 2,760,029 18.8 %Revenue generating compression units (at period end) 4,559 4,629 (1.5)%Average horsepower per revenue generating compression unit (5) 720 687 4.8 %Horsepower utilization (6): At period end 93.7% 94.0% (0.3)%Average for the period (7) 94.1% 91.4% 3.0 %________________________________(1)Fleet horsepower is horsepower for compression units that have been delivered to us (and excludes units on order).

Horsepower utilization based on revenue generating horsepower and fleet horsepower was 89.9% and 90.7% at December 31,2019 and 2018, respectively.(7)Calculated as the average utilization for the months in the period based on utilization at the end of each month in the period. Average horsepower utilization based onrevenue generating horsepower and fleet horsepower was 89.8% and 87.5% for the years ended December 31, 2019 and 2018, respectively. Many of our compression units contain devices that enable us to monitor the units remotely through cellular and satellite networks to supplement ourtechnicians’ on-site monitoring visits. We intend to continue to selectively add remote monitoring systems to our new and existing fleet during 2020 wherebeneficial from an operational and financial standpoint. All of our compression units are designed to automatically shut down if operating conditions deviate froma pre-determined range. While we retain the care, custody, ongoing maintenance and control of our compression units, we allow our customers, subject to a definedprotocol, to start, stop, accelerate and slow down compression units in response to field conditions.We adhere to routine, preventive and scheduled maintenance cycles. Each of our compression units is subjected to rigorous sizing and diagnostic analyses,including lubricating oil analysis and engine exhaust emission analysis. We have proprietary field service automation capabilities that allow our service techniciansto electronically record and track operating, technical, environmental and commercial information at the discrete unit level. These capabilities allow our fieldtechnicians to identify potential problems and often act on them before such problems result in down-time.Generally, we expect each of our compression units to undergo a major overhaul between service deployment cycles. The timing of these major overhaulsdepends on multiple factors, including run time and operating conditions. A major overhaul involves the periodic rebuilding of the unit to materially extend itseconomic useful life or to enhance the unit’s ability to fulfill broader or more diversified compression applications. Because our compression fleet is comprised ofunits of varying horsepower that have been placed into service with staggered initial on-line dates, we are able to schedule overhauls in a way that avoids excessiveannual maintenance capital expenditures and minimizes the revenue impact of down-time.6Table of ContentsWe believe that our customers, by outsourcing their compression requirements, can achieve higher compression run-times, which translates into increasedvolumes of either natural gas or crude oil production and, therefore, increased revenues. Utilizing our compression services also allows our customers to reducetheir operating, maintenance and equipment costs by allowing us to efficiently manage their changing compression needs. In many of our service contracts, weguarantee our customers availability (as described below) ranging from 95% to 98%, depending on field-level requirements.Marketing and SalesOur marketing and client service functions are performed on a coordinated basis by our sales team and field technicians. Salespeople, applications engineersand field technicians qualify, analyze and scope new compression applications as well as regularly visit our customers to ensure customer satisfaction, determine acustomer’s needs related to existing services being provided and determine the customer’s future compression service requirements. This ongoing communicationallows us to quickly identify and respond to our customers’ compression requirements.CustomersOur customers consist of more than 375 companies in the energy industry, including major integrated oil companies, public and private independentexploration and production companies and midstream companies. Our ten largest customers accounted for approximately 33%, 33% and 43% of our revenue forthe years ended December 31, 2019, 2018 and 2017, respectively.Suppliers and Service ProvidersThe principal manufacturers of components for our natural gas compression equipment include Caterpillar, Inc., Cummins Inc., and Arrow Engine Companyfor engines, Air-X-Changers and Alfa Laval (US) for coolers, and Ariel Corporation, GE Oil & Gas Gemini products and Arrow Engine Company for compressorframes and cylinders. We also rely primarily on four vendors, A G Equipment Company, Alegacy Equipment, LLC, Standard Equipment Corp. and GenisHoldings LLC, to package and assemble our compression units. Although we rely primarily on these suppliers, we believe alternative sources for natural gascompression equipment are generally available if needed. However, relying on alternative sources may increase our costs and change the standardized nature ofour fleet. We have not experienced any material supply problems to date. Although lead-times for new Caterpillar engines and new Ariel compressor frames havein the past been in excess of one year due to increased demand and supply allocations imposed on equipment packagers and end-users, as of December 31, 2019,lead-times for such engines and frames are approximately six months. Please read Part I, Item 1A “Risk Factors – Risks Related to Our Business – We depend on alimited number of suppliers and are vulnerable to product shortages and price increases, which could have a negative impact on our results of operations”.CompetitionThe compression services business is highly competitive. Some of our competitors have a broader geographic scope and greater financial and other resourcesthan we do. On a regional basis, we experience competition from numerous smaller companies that may be able to more quickly adapt to changes within ourindustry and changes in economic conditions as a whole, more readily take advantage of available opportunities and adopt more aggressive pricing policies.Additionally, the historical availability of attractive financing terms from financial institutions and equipment manufacturers has made the purchase of individualcompression units affordable to our customers. We believe that we compete effectively on the basis of price, equipment availability, customer service, flexibility inmeeting customer needs, quality and reliability of our compressors and related services. Please read Part I, Item 1A “Risk Factors – Risks Related to Our Business– We face significant competition that may cause us to lose market share and reduce our cash available for distribution”.SeasonalityOur results of operations have not historically been materially affected by seasonality, and we do not currently have reason to believe that seasonalfluctuations will have a material impact in the foreseeable future.InsuranceWe believe that our insurance coverage is customary for the industry and adequate for our business. As is customary in the energy services industry, wereview our safety equipment and procedures and carry insurance against most, but not all, risks of our business. Losses and liabilities not covered by insurancewould increase our costs. The compression business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of gas or well fluids, firesand explosions or environmental damage. To address the hazards inherent in our business, we maintain insurance coverage that, subject to significant deductibles,7Table of Contentsincludes physical damage coverage, third party general liability insurance, employer’s liability, environmental and pollution and other coverage, although coveragefor environmental and pollution related losses is subject to significant limitations. Under the terms of our standard compression services contract, we areresponsible for maintaining insurance coverage on our compression equipment. Please read Part I, Item 1A “Risk Factors – Risks Related to Our Business – We donot insure against all potential losses and could be seriously harmed by unexpected liabilities”.Environmental and Safety RegulationsWe are subject to stringent and complex federal, state and local laws and regulations governing the discharge of materials into the environment or otherwiserelating to protection of human health, safety and the environment. These regulations include compliance obligations for air emissions, water quality, wastewaterdischarges and solid and hazardous waste disposal, as well as regulations designed for the protection of human health and safety and threatened or endangeredspecies. Compliance with these environmental laws and regulations may expose us to significant costs and liabilities and cause us to incur significant capitalexpenditures in our operations. We are often obligated to assist customers in obtaining permits or approvals in our operations from various federal, state and localauthorities. Permits and approvals can be denied or delayed, which may cause us to lose potential and current customers, interrupt our operations and limit ourgrowth and revenue. Moreover, failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties,imposition of remedial obligations and the issuance of injunctions delaying or prohibiting operations. Private parties may also have the right to pursue legal actionsto enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property damage. While webelieve that our operations are in substantial compliance with applicable environmental laws and regulations and that continued compliance with currentrequirements would not have a material adverse effect on us, we cannot predict whether our cost of compliance will materially increase in the future. Any changesin, or more stringent enforcement of, existing environmental laws and regulations, or passage of additional environmental laws and regulations that result in morestringent and costly pollution control equipment, waste handling, storage, transport, disposal or remediation requirements could have a material adverse effect onour operations and financial position.We do not believe that compliance with federal, state or local environmental laws and regulations will have a material adverse effect on our business,financial position or results of operations or cash flows. We cannot assure you, however, that future events such as changes in existing laws or enforcementpolicies, the promulgation of new laws or regulations, or the development or discovery of new facts or conditions or unforeseen incidents will not cause us to incursignificant costs. The following is a discussion of material environmental and safety laws that relate to our operations. We believe that we are in substantialcompliance with all of these environmental laws and regulations. Please read Part I, Item 1A “Risk Factors – Risks Related to Our Business – We are subject tosubstantial environmental regulation, and changes in these regulations could increase our costs or liabilities”.Air emissions. The Clean Air Act (“CAA”) and comparable state laws regulate emissions of air pollutants from various industrial sources, including naturalgas compressors, and impose certain monitoring and reporting requirements. Such emissions are regulated by air emissions permits, which are applied for andobtained through various state or federal regulatory agencies. Our standard natural gas compression contract provides that the customer is responsible for obtainingair emissions permits and assuming the environmental risks related to site operations. In some instances, our customers may be required to aggregate emissionsfrom a number of different sources on the theory that the different sources should be considered a single source. Any such determinations could have the effect ofmaking projects more costly than our customers expected and could require the installation of more costly emissions controls, which may lead some of ourcustomers not to pursue certain projects.Increased obligations of operators to reduce air emissions of nitrogen oxides and other pollutants from internal combustion engines in transmission servicehave been enacted by governmental authorities. For example, in 2010, the U.S. Environmental Protection Agency (“EPA”) published new regulations under theCAA to control emissions of hazardous air pollutants from existing stationary reciprocal internal combustion engines, also known as Quad Z regulations. Therule requires us to undertake certain expenditures and activities, including purchasing and installing emissions control equipment on certain compressor enginesand generators.In recent years, the EPA has lowered the National Ambient Air Quality Standards (“NAAQS”) for several air pollutants. For example, in 2015, the EPAfinalized a rule strengthening the primary and secondary standards for ground level ozone, both of which are 8-hour concentration standards of 70 parts per billion.After the EPA revises a NAAQS standard, the states are expected to establish revised attainment/non-attainment regions. State implementation of the revisedNAAQS could result in stricter permitting requirements, delay or prohibit our customers’ ability to obtain such permits, and result in increased expenditures forpollution control equipment, which could impact our customers’ operations, increase the cost of additions to property, plant, and equipment, and negatively impactour business.8Table of ContentsIn 2012, the EPA finalized rules that establish new air emissions controls for oil and natural gas production and natural gas processing operations.Specifically, the EPA’s rule package included New Source Performance Standards to address emissions of sulfur dioxide and volatile organic compounds(“VOCs”) and a separate set of emissions standards to address hazardous air pollutants frequently associated with oil and natural gas production and processingactivities. The rules established specific new requirements regarding emissions from compressors and controllers at natural gas processing plants, dehydrators,storage tanks and other production equipment as well as the first federal air standards for natural gas wells that are hydraulically fractured. In June 2016, the EPAtook steps to expand on these regulations when it published New Source Performance Standards, known as Subpart OOOOa, that require certain new, modified orreconstructed facilities in the oil and natural gas sector to reduce methane gas and VOC emissions. These Subpart OOOOa standards would expand the 2012 NewSource Performance Standards by using certain equipment-specific emissions control practices, requiring additional controls for pneumatic controllers and pumpsas well as compressors, and imposing leak detection and repair requirements for natural gas compressor and booster stations. However, the EPA announced inApril 2017 that it intended to reconsider certain aspects of the 2016 New Source Performance Standards, and in May 2017, the EPA issued an administrative stayof key provisions of the rule, but was promptly ordered by the D.C. Circuit to implement the rule. The EPA also proposed 60-day and two-year stays of certainprovisions in June 2017 and published a Notice of Data Availability in November 2017 seeking comment and providing clarification regarding the agency’s legalauthority to stay the rule. In March 2018, EPA finalized narrow amendments to the rule, and in October 2018, EPA proposed further reconsideration amendmentsto the rule. Among other things, these amendments would alter fugitive emissions requirements, monitoring frequencies, and well site pneumatic pumpstandards. In September 2019, the EPA published a proposed rulemaking amending the June 2016 regulations that, among other things, would remove sources inthe transmission and storage segment from the oil and natural gas source category and rescind the methane-specific requirements applicable to sources in theproduction and processing segments of the industry. As an alternative, EPA also proposed to rescind the methane-specific requirements that apply to all sources inthe oil and natural gas industry, without removing the transmission and storage sources from the current source category. Under either alternative, EPA plans toretain emissions limits for volatile organic compounds. The EPA proposed rulemaking indicates that the controls to reduce volatile organic compound emissionsalso reduce methane at the same time, so separate methane limitations for these segments of the industry are redundant. Whether these proposed standards maybecome implemented, on what date and exactly what they will require is unknown at this time.Depending upon whether EPA finalizes these further amendments or promulgates any additional regulation of air emissions from the oil and gas sector couldresult in increased expenditures for pollution control equipment, which could impact our customers’ operations and negatively impact our business.We are also subject to air regulation at the state level. For example, the Texas Commission on Environmental Quality (“TCEQ”) has finalized revisions tocertain air permit programs that significantly increase the air permitting requirements for new and certain existing oil and gas production and gathering sites for 15counties in the Barnett Shale production area. The final rule establishes new emissions standards for engines, which could impact the operation of specificcategories of engines by requiring the use of alternative engines, compressor packages or the installation of aftermarket emissions control equipment. The rulebecame effective for the Barnett Shale production area in April 2011, with the lower emissions standards becoming applicable between 2015 and 2030 dependingon the type of engine and the permitting requirements. The cost to comply with the revised air permit programs is not expected to be material at thistime. However, the TCEQ has stated it will consider expanding application of the new air permit program statewide. At this point, we cannot predict the cost tocomply with such requirements if the geographic scope is expanded.There can be no assurance that future requirements compelling the installation of more sophisticated emissions control equipment would not have a materialadverse impact on our business, financial condition, results of operations and cash available for distribution.Climate change. Methane, a primary component of natural gas, and carbon dioxide, a byproduct of the burning of natural gas, are examples of greenhousegases (“GHGs”). In recent years, the U.S. Congress has considered legislation to reduce GHG emissions. Federal and possibly state governments may imposesignificant and potentially draconian restrictions on fossil-fuel exploration, production and use if pledges made by certain candidates seeking various politicaloffices were enacted into law. Some proposals include bans on hydraulic fracturing of oil and gas wells, bans on new leases for production of minerals on federalproperties, and imposing restrictive requirements on new pipeline infrastructure or fossil-fuel export facilities. Other energy legislation and initiatives could includea carbon tax or cap and trade program. Further, although Congress has not passed such legislation, almost half of the states have begun to address GHG emissions,primarily through the planned development of emissions inventories or regional GHG cap and trade programs. Depending on the particular program, we could berequired to control GHG emissions or to purchase and surrender allowances for GHG emissions resulting from our operations.Independent of Congress, the EPA undertook to adopt regulations controlling GHG emissions under its existing CAA authority. For example, in 2009, theEPA officially published its findings that emissions of carbon dioxide, methane and other GHGs endanger9Table of Contentshuman health and the environment, allowing the agency to proceed with the adoption of regulations that restrict emissions of GHG under existing provisions of theCAA. In 2009 and 2010, the EPA adopted rules regarding regulation of GHG emissions from motor vehicles and requiring the reporting of GHG emissions in theU.S. from specified large GHG emissions sources, including petroleum and natural gas facilities such as natural gas transmission compression facilities that emit25,000 metric tons or more of carbon dioxide equivalent per year.In 2015, the EPA published standards of performance for GHG emissions from new power plants. The final rule establishes a performance standard forintegrated gasification combined cycled units and utility boilers based on the use of the best system of emissions reduction that the EPA has determined has beenadequately demonstrated for each type of unit. The rule also sets limits for stationary natural gas combustion turbines based on the use of natural gas combinedcycle technology.The EPA also promulgated the Clean Power Plan rule (“CPP”), which is intended to reduce carbon emissions from existing power plants by 32 percent from2005 levels by 2030. In 2019, the EPA finalized the Affordable Clean Energy rule (“ACE”) to replace the CPP, providing states with authority to regulate GHGsfrom coal-fired power plants, and establish heat rate improvements as the best system of emissions reduction. The ACE rule has been challenged in court and thefinal outcome of that litigation is uncertain. If the ACE Rule results in state plans to significantly reduce the level of GHG emissions from electric utility generatingunits, or if the effort to replace the CPP with the ACE rule is unsuccessful and rules similar to the CPP are upheld to control GHG emissions from electric utilitygenerating units, demand for the oil and natural gas our customers produce may decrease. In addition, the costs of electricity for our operations may also increase,thereby adversely impacting our business.In addition to the EPA, the Bureau of Land Management (“BLM”) has also promulgated rules to regulate hydraulic fracturing. Hydraulic fracturing involvesthe injection of water, sand and chemicals under pressure into the rock formation to stimulate gas production. In 2015, the BLM promulgated new requirementsrelating to well construction, water management, and chemical disclosure for companies drilling on federal and tribal land, but subsequently finalized a rule inDecember 2017 rescinding the 2015 rule. This rescission has been challenged and that litigation is ongoing. If this rescission is not upheld, it could increase thecosts of operation for our customers who operate on BLM land, and negatively impact our business. Additionally, on November 15, 2016, the BLM also finalizeda rule to reduce the flaring, venting and leaking of methane from oil and gas operations on federal and Indian lands (the “Venting Rule”). The Venting Rulerequires operators to use certain technologies and equipment to reduce flaring and to periodically inspect their operations for leaks. The Venting Rule also specifieswhen operators owe the government royalties for flared gas. In December 2017, BLM finalized a decision to delay implementation of key requirements in theVenting Rule for one year. The agency subsequently finalized a rule in September 2018 to revise the 2016 Venting rule (the “Revised Venting Rule”) by rescindingcertain requirements, such as the requirement to use certain technologies and equipment, as well as the leak detection and repair requirement. The Revised VentingRule also specifies that BLM will defer to the appropriate State or tribal authorities in determining whether royalties are owed for flared gas. Challenges to theVenting Rule and the Revised Venting Rule are pending in court. If the Revised Venting Rule is not upheld, and the Venting Rule is fully implemented, it couldincrease the costs of operations for our customers who operate on BLM land, and negatively impact our business.Some states have also passed legislation or regulations regarding hydraulic fracturing. For example, in 2019, Colorado passed Senate Bill 181, whichdelegates authority to local governments to regulate oil and gas activities and requires the Colorado Oil and Gas Conservation Commission to minimize emissionsof methane and other air contaminants. Some local communities have adopted additional restrictions for oil and gas activities, such as requiring greater setbacks,and some groups are petitioning local governments to ban hydraulic fracturing. If additional regulatory measures are adopted, customers in Colorado couldexperience delays, limitations, or prohibitions on their activities. Such delays, limitations, or prohibitions could result in decreased demand for our services.Litigation risks are also increasing, as a number of cities, local governments and other plaintiffs have sued companies engaged in the exploration andproduction of fossil fuels in state and federal courts, alleging various legal theories to recover for the impacts of alleged global warming effects, such as rising sealevels. Many of these suits allege that the companies have been aware of the adverse effects of climate change for some time but defrauded their investors byfailing to adequately disclose those impacts. Although a number of these lawsuits have been dismissed, others remain pending and the outcome of these casesremains difficult to predict.At the international level, nearly 200 nations entered into an international climate agreement at the 2015 United Nations Framework Convention on ClimateChange in Paris, under which participating countries did not assume any binding obligation to reduce future emissions of GHGs but instead pledged to voluntarilylimit or reduce future emissions. Although the U.S. became a party to the Paris Agreement in April 2016, the Trump administration announced in June 2017 itsintention to either withdraw from the Paris Agreement or renegotiate more favorable terms. However, the Paris Agreement stipulates that participating countriesmust wait four years before withdrawing from the agreement. Despite the planned withdrawal, certain U.S. city and state governments have announced theirintention to satisfy their proportionate obligations under the Paris Agreement.10Table of ContentsAlthough it is not currently possible to predict with specificity how any proposed or future GHG legislation, regulation, agreements or initiatives will impactour business, any legislation or regulation of GHG emissions that may be imposed in areas in which we conduct business or on the assets we operate could result inincreased compliance or operating costs or additional operating restrictions or reduced demand for our services, and could have a material adverse effect on ourbusiness, financial condition and results of operations. Notwithstanding potential risks related to climate change, the International Energy Agency estimates that oiland gas will continue to represent a major share of global energy use through 2040, and other private sector studies project continued growth in demand for thenext two decades. However, recent activism directed at shifting funding away from companies with energy-related assets could result in limitations or restrictionson certain sources of funding for the energy sector.Finally, it should be noted that some scientists have concluded that increasing concentrations of GHG in Earth’s atmosphere may produce climate changesthat have significant weather-related effects, such as increased frequency and severity of storms, droughts, floods and other climatic events. If any of those effectswere to occur, they could have an adverse effect on our assets and operations.Water discharge. The Clean Water Act (“CWA”) and analogous state laws impose restrictions and strict controls with respect to the discharge of pollutants,including spills and leaks of oil and other substances, into waters of the United States. The discharge of pollutants into regulated waters is prohibited, except inaccordance with the terms of a permit issued by the EPA or an analogous state agency. The CWA and regulations implemented thereunder also prohibit thedischarge of dredge and fill material into regulated waters, including jurisdictional wetlands, unless authorized by an appropriately issued permit. The CWA alsorequires the development and implementation of spill prevention, control and countermeasures, including the construction and maintenance of containment bermsand similar structures, if required, to help prevent the contamination of navigable waters in the event of a petroleum hydrocarbon tank spill, rupture or leak at suchfacilities. In addition, the CWA and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff fromcertain types of facilities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties as well as other enforcement mechanismsfor non-compliance with discharge permits or other requirements of the CWA and analogous state laws and regulations.Our compression operations do not generate process wastewaters that are discharged to waters of the United States. In any event, our customers assumeresponsibility under the majority of our standard natural gas compression contracts for obtaining any permits that may be required under the CWA, whether fordischarges or developing property by filling wetlands. Considerable legal uncertainty exists surrounding the standard for what constitutes jurisdictional waters andwetlands subject to the protections and requirements of the CWA. A 2015 EPA rulemaking that would have significantly expanded the scope of jurisdictionalwaters has been repealed by a recent rulemaking in October 2019 by the EPA and the U.S. Army Corps of Engineers. Should the 2019 repeal be vacated and the2015 rule take effect, or should a different rule expand the jurisdictional reach of the CWA, our customers could face increased costs and delays due to additionalpermitting and regulatory requirements and possible challenges to permitting decisions.Safe Drinking Water Act. A significant portion of our customers’ natural gas production is developed from unconventional sources that require hydraulicfracturing as part of the completion process. Legislation to amend the Safe Drinking Water Act (“SDWA”) to repeal the exemption for hydraulic fracturing fromthe definition of “underground injection” and require federal permitting and regulatory control of hydraulic fracturing, as well as legislative proposals to requiredisclosure of the chemical constituents of the fluids used in the fracturing process, have been proposed and the U.S. Congress continues to consider legislation toamend the SDWA. Scrutiny of hydraulic fracturing activities continues in other ways, with the EPA having commenced a multi-year study of the potentialenvironmental impacts of hydraulic fracturing. In December 2016, the EPA released its final report on the potential impacts of hydraulic fracturing on drinkingwater resources. The final report concluded that “water cycle” activities associated with hydraulic fracturing may impact drinking water resources “under somecircumstances,” noting that the following hydraulic fracturing water cycle activities and local- or regional-scale factors are more likely than others to result in morefrequent or more severe impacts: water withdrawals for fracturing in times or areas of low water availability; surface spills during the management of fracturingfluids, chemicals or produced water; injection of fracturing fluids into wells with inadequate mechanical integrity; injection of fracturing fluids directly intogroundwater resources; discharge of inadequately treated fracturing wastewater to surface waters; and disposal or storage of fracturing wastewater in unlined pits.The EPA has also announced that it believes hydraulic fracturing using fluids containing diesel fuel can be regulated under the SDWA notwithstanding theSDWA’s general exemption for hydraulic fracturing. Several states have also proposed or adopted legislative or regulatory restrictions on hydraulic fracturing,including prohibitions on the practice. We cannot predict the future of such legislation and what additional, if any, provisions would be included. If additionallevels of regulation, restrictions and permits were required through the adoption of new laws and regulations at the federal or state level or if the agencies that issuethe permits develop new interpretations of those requirements, that could lead to delays, increased operating costs and process prohibitions that could reducedemand for our compression services, which could materially adversely affect our revenue and results of operations.11Table of ContentsSolid waste. The Resource Conservation and Recovery Act (“RCRA”) and comparable state laws control the management and disposal of hazardous and non-hazardous waste. These laws and regulations govern the generation, storage, treatment, transfer and disposal of wastes that we generate including, but not limitedto, used oil, antifreeze, filters, sludges, paint, solvents and sandblast materials. The EPA and various state agencies have limited the approved methods of disposalfor these types of wastes.Site remediation. The Comprehensive Environmental Response Compensation and Liability Act (“CERCLA”) and comparable state laws impose strict, jointand several liability without regard to fault or the legality of the original conduct on certain classes of persons that contributed to the release of a hazardoussubstance into the environment. These persons include the owner and operator of a disposal site where a hazardous substance release occurred and any companythat transported, disposed of or arranged for the transport or disposal of hazardous substances released at the site. Under CERCLA, such persons may be liable forthe costs of remediating the hazardous substances that have been released into the environment, for damages to natural resources, and for the costs of certain healthstudies. In addition, where contamination may be present, it is not uncommon for the neighboring landowners and other third parties to file claims for personalinjury, property damage and recovery of response costs. While we generate materials in the course of our operations that may be regulated as hazardoussubstances, we have not received notification that we may be potentially responsible for cleanup costs under CERCLA at any site.While we do not currently own or lease any material facilities or properties for storage or maintenance of our inactive compression units, we may use thirdparty properties for such storage and possible maintenance and repair activities. In addition, our active compression units typically are installed on propertiesowned or leased by third party customers and operated by us pursuant to terms set forth in the natural gas compression services contracts executed by thosecustomers. Under most of our natural gas compression services contracts, our customers must contractually indemnify us for certain damages we may suffer as aresult of the release into the environment of hazardous and toxic substances. We are not currently responsible for any remedial activities at any properties we use;however, there is always the possibility that our future use of those properties may result in spills or releases of petroleum hydrocarbons, wastes or other regulatedsubstances into the environment that may cause us to become subject to remediation costs and liabilities under CERCLA, RCRA or other environmental laws. Wecannot provide any assurance that the costs and liabilities associated with the future imposition of such remedial obligations upon us would not have a materialadverse effect on our operations or financial position.Safety and health. The Occupational Safety and Health Act (“OSHA”) and comparable state laws strictly govern the protection of the health and safety ofemployees. The OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of CERCLA and similar state statutesrequire that we organize and, as necessary, disclose information about hazardous materials used or produced in our operations to various federal, state and localagencies, as well as employees.EmployeesUSA Compression Management Services, LLC (“USAC Management”), a wholly owned subsidiary of the General Partner, performs certain management andother administrative services for us, such as accounting, corporate development, finance and legal. All of our employees, including our executive officers, areemployees of USAC Management. As of December 31, 2019, USAC Management had 879 full time employees. None of our employees are subject to collectivebargaining agreements. We consider our employee relations to be good.Available InformationOur website address is usacompression.com.

The information contained on our website does not constitute part of this report.The SEC maintains a website that contains these reports at sec.gov.ITEM 1A.Risk FactorsAs described in Part I “Disclosure Regarding Forward-Looking Statements”, this report contains forward-looking statements regarding us, our business andour industry. The risk factors described below, among others, could cause our actual results to differ materially from the expectations reflected in the forward-looking statements. If any of the following risks were to materialize, our business, financial condition or results of operations could be materially and adverselyaffected. In that case, we might not be able to continue to pay our current quarterly distribution on our common units or increase the level of such distributions inthe future, and the trading price of our common units could decline.12Table of ContentsRisks Related to Our BusinessWe may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and expenses, including costreimbursements to the General Partner, to enable us to make cash distributions on our common units at the current level.In order to make cash distributions at our current distribution rate of $0.525 per common unit per quarter, or $2.10 per common unit per year, we will requireavailable cash of $50.7 million per quarter, or $203.0 million per year, based on the number of common units outstanding as of February 13, 2020.Furthermore, our Second Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”) prohibits us from paying distributions onour common units unless we have first paid the quarterly distribution on the Preferred Units, including any previously accrued but unpaid distributions on thePreferred Units. The Preferred Unit distributions require $12.2 million quarterly, or $48.8 million annually, based on the number of Preferred Units outstanding andthe distribution rate of $24.375 per Preferred Unit per quarter, or $97.50 per Preferred Unit per year.Under our cash distribution policy, the amount of cash we can distribute to our unitholders principally depends upon the amount of cash we generate from ouroperations, which will fluctuate from quarter to quarter based on, among other things:•the level of production of, demand for, and price of natural gas and crude oil, particularly the level of production in the regions where we providecompression services;•the fees we charge, and the margins we realize, from our compressionservices;•the cost of achieving organic growth in current and new markets;•the ability to effectively integrate any assets or businesses weacquire;•the level of competition from other companies;and•prevailing global and regional economic and regulatory conditions, and their impact on us and ourcustomers.In addition, the actual amount of cash we will have available for distribution will depend on other factors, including:•the levels of our maintenance and expansion capitalexpenditures;•the level of our operating costs andexpenses;•our debt service requirements and otherliabilities;•fluctuations in our working capitalneeds;•restrictions contained in the Credit Agreement or the Indentures (the “Indentures”) governing the Senior Notes 2026 and Senior Notes 2027 (collectively,the “Senior Notes”);•the cost of acquisitions;•fluctuations in interest rates;•the financial condition of ourcustomers;•our ability to borrow funds and access the capital markets; and•the amount of cash reserves established by the General Partner.A long-term reduction in the demand for, or production of, natural gas or crude oil could adversely affect the demand for our services or the prices wecharge for our services, which could result in a decrease in our revenues and cash available for distribution to unitholders.The demand for our compression services depends upon the continued demand for, and production of, natural gas and crude oil. Demand may be affected by,among other factors, natural gas prices, crude oil prices, weather, availability of alternative energy sources, governmental regulation and the overall demand forenergy. Any prolonged, substantial reduction in the demand for13Table of Contentsnatural gas or crude oil would likely depress the level of production activity and result in a decline in the demand for our compression services, which could resultin a reduction in our revenues and our cash available for distribution.In particular, lower natural gas or crude oil prices over the long term could result in a decline in the production of natural gas or crude oil, respectively,resulting in reduced demand for our compression services. For example, the North American rig count, as measured by Baker Hughes, hit a 2014 peak of 1,931 rigson September 12, 2014, and at that time, Henry Hub natural gas spot prices were $3.82 per one million British thermal units (“MMBtu”) and West TexasIntermediate (“WTI”) crude oil spot prices were $92.18 per barrel. By contrast, the North American rig count hit a modern low of 404 rigs on May 20, 2016, andat that time, Henry Hub natural gas spot prices were $1.81 per MMBtu and WTI crude oil spot prices were $47.67 per barrel. This slowdown in new drillingactivity caused some pressure on service rates for new and existing services and contributed to a decline in our utilization during 2015 and into 2016. By the end ofDecember 2019, the North American rig count was 805 rigs, the price of WTI crude oil was $61.14 per barrel and Henry Hub natural gas spot prices were $2.09per MMBtu. Although commodity prices and our utilization generally increased from 2016 through 2019, the increased activity resulting from such increasedcommodity prices may not continue. In addition, a small portion of our fleet is used in gas lift applications in connection with crude oil production using horizontaldrilling techniques. During the period of low crude oil prices, we experienced pressure on service rates from our customers in gas lift applications; if commodityprices decline from current levels, we may again experience pressure on service rates.Additionally, an increasing percentage of natural gas and crude oil production comes from unconventional sources, such as shales, tight sands and coalbeds.Such sources can be less economically feasible to produce in low commodity price environments, in part due to costs related to compression requirements, and areduction in demand for natural gas or gas lift for crude oil may cause such sources of natural gas or crude oil to become uneconomic to drill and produce, whichcould in turn negatively impact the demand for our services. Further, if demand for our services decreases, we may be asked to renegotiate our service contracts atlower rates. In addition, governmental regulation and tax policy may impact the demand for natural gas or crude oil or impact the economic feasibility of thedevelopment of new fields or production of existing fields, which are important components of our ability to expand.We have several key customers. The loss of any of these customers would result in a decrease in our revenues and cash available for distribution.We provide compression services under contracts with several key customers. The loss of one of these key customers may have a greater effect on ourfinancial results than for a company with a more diverse customer base. Our ten largest customers accounted for approximately 33%, 33% and 43% of our revenuefor the years ended December 31, 2019, 2018 and 2017, respectively. The loss of all or even a portion of the compression services we provide to our key customers,as a result of competition or otherwise, could have a material adverse effect on our business, results of operations, financial condition and cash available fordistribution.The deterioration of the financial condition of our customers could adversely affect our business.During times when the natural gas or crude oil markets weaken, our customers are more likely to experience financial difficulties, including being unable toaccess debt or equity financing, which could result in a reduction in our customers’ spending for our services. For example, our customers could seek to preservecapital by using lower cost providers, not renewing month-to-month contracts or determining not to enter into any new compression service contracts. A significantdecline in commodity prices may cause certain of our customers to reconsider their near-term capital budgets, which may impact large-scale natural gasinfrastructure and crude oil production activities. Reduced demand for our services could adversely affect our business, results of operations, financial conditionand cash flows.We are exposed to counterparty credit risk. Nonpayment and nonperformance by our customers, suppliers or vendors could reduce our revenues, increaseour expenses and otherwise have a negative impact on our ability to conduct our business, operating results, cash flows and ability to make distributions to ourunitholders.Weak economic conditions and widespread financial distress could reduce the liquidity of our customers, suppliers or vendors, making it more difficult forthem to meet their obligations to us. We are therefore subject to risks of loss resulting from nonpayment or nonperformance by our customers. Severe financialproblems encountered by our customers could limit our ability to collect amounts owed to us, or to enforce the performance of obligations owed to us undercontractual arrangements. In the event that any of our customers was to enter into bankruptcy, we could lose all or a portion of the amounts owed to us by suchcustomer, and we may be forced to cancel all or a portion of our service contracts with such customer at significant expense to us.14Table of ContentsIn addition, nonperformance by suppliers or vendors who have committed to provide us with critical products or services could raise our costs or interfere withour ability to successfully conduct our business.We face significant competition that may cause us to lose market share and reduce our cash available for distribution.The natural gas compression business is highly competitive. Some of our competitors have a broader geographic scope and greater financial and otherresources than we do. Our ability to renew or replace existing contracts with our customers at rates sufficient to maintain current revenue and cash flows could beadversely affected by the activities of our competitors and our customers. If our competitors substantially increase the resources they devote to the developmentand marketing of competitive services or substantially decrease the prices at which they offer their services, we may be unable to compete effectively. Some ofthese competitors may expand or construct newer, more powerful or more flexible compression fleets, which would create additional competition for us. All ofthese competitive pressures could have a material adverse effect on our business, results of operations, financial condition and cash available for distribution.Our customers may choose to vertically integrate their operations by purchasing and operating their own compression fleet, increasing the number ofcompression units they currently own or using alternative technologies for enhancing crude oil production.Our customers that are significant producers, processors, gatherers and transporters of natural gas and crude oil may choose to vertically integrate theiroperations by purchasing and operating their own compression fleets in lieu of using our compression services. The historical availability of attractive financingterms from financial institutions and equipment manufacturers facilitates this possibility by making the purchase of individual compression units increasinglyaffordable to our customers. In addition, there are many technologies available for the artificial enhancement of crude oil production, and our customers may electto use these alternative technologies instead of the gas lift compression services we provide. Such vertical integration, increases in vertical integration or use ofalternative technologies could result in decreased demand for our compression services, which may have a material adverse effect on our business, results ofoperations, financial condition and reduce our cash available for distribution.A significant portion of our services are provided to customers on a month-to-month basis, and we cannot be sure that such customers will continue toutilize our services.Our contracts typically have an initial term of between six months and five years, depending on the application and location of the compression unit. After theexpiration of the initial term, the contract continues on a month-to-month or longer basis until terminated by us or our customers upon notice as provided for in theapplicable contract. For the year ended December 31, 2019, approximately 36% of our compression services on a revenue basis were provided on a month-to-month basis to customers who continue to utilize our services following expiration of the primary term of their contracts. These customers can generally terminatetheir month-to-month compression services contracts on 30 days’ written notice. If a significant number of these customers were to terminate their month-to-monthservices, or attempt to renegotiate their month-to-month contracts at substantially lower rates, it could have a material adverse effect on our business, results ofoperations, financial condition and cash available for distribution.We may be unable to grow our cash flows if we are unable to expand our business, which could limit our ability to maintain or increase the level ofdistributions to our common unitholders.A principal focus of our strategy is to maintain or increase our per common unit distribution by expanding our business over time. Our future growth willdepend upon a number of factors, some of which we cannot control. These factors include our ability to:•develop new business and enter into service contracts with newcustomers;•retain our existing customers and maintain or expand the services we providethem;•maintain or increase the fees we charge, and the margins we realize, from our compressionservices;•recruit and train qualified personnel and retain valued employees;•expand our geographicpresence;•effectively manage our costs and expenses, including costs and expenses related togrowth;•consummate accretive acquisitions;•obtain required debt or equity financing on favorable terms for our existing and new operations;and15Table of Contents•meet customer specific contract requirements or pre-qualifications.If we do not achieve our expected growth, we may not be able to maintain or increase the level of distributions on our common units, in which event themarket price of our common units will likely decline.We may be unable to grow successfully through acquisitions, which may negatively impact our operations and limit our ability to maintain or increase thelevel of distributions on our common units.From time to time, we may choose to make business acquisitions, such as the CDM Acquisition, to pursue market opportunities, increase our existingcapabilities and expand into new geographic areas of operations. While we have reviewed acquisition opportunities in the past and will continue to do so in thefuture, we may not be able to identify attractive acquisition opportunities or successfully acquire identified targets.Any acquisitions we do complete may require us to issue a substantial amount of equity or incur a substantial amount of indebtedness. If we consummate anyfuture material acquisitions, our capitalization may change significantly, and unitholders will not have the opportunity to evaluate the economic, financial andother relevant information that we will consider in connection with any future acquisition. Furthermore, competition for acquisition opportunities may escalate,increasing our costs of pursuing acquisitions or causing us to refrain from making acquisitions.Also, our reviews of proposed business or asset acquisitions are inherently imperfect because it is generally not feasible to perform an in-depth review of eachsuch proposal given time constraints imposed by sellers. Even if performed, a detailed review of assets and businesses may not reveal existing or potentialproblems, and may not provide sufficient familiarity with such business or assets to fully assess their deficiencies and potential. Inspections may not be performedon every asset, and environmental problems, such as groundwater contamination, may not be observable even when an inspection is undertaken.Integration of assets acquired in past acquisitions or future acquisitions with our existing business can be a complex, time-consuming and costly process,particularly in the case of material acquisitions such as the CDM Acquisition, which significantly increased our size and expanded the geographic areas inwhich we operate. A failure to successfully integrate the acquired assets with our existing business in a timely manner may have a material adverse effect onour business, financial condition, results of operations or cash available for distribution to our unitholders.The difficulties of integrating past and future acquisitions with our business include, among other things:•operating a larger combined organization in new geographic areas and new lines ofbusiness;•hiring, training or retaining qualified personnel to manage and operate our growing business andassets;•integrating management teams and employees into existing operations and establishing effective communication and information exchange with suchmanagement teams and employees;•diversion of management’s attention from our existingbusiness;•assimilation of acquired assets and operations, including additional regulatoryprograms;•loss ofcustomers;•loss of key employees;•maintaining an effective system of internal controls in compliance with the Sarbanes-Oxley Act of 2002 as well as other regulatory compliance andcorporate governance matters; and•integrating new technology systems for financialreporting.If any of these risks or other unanticipated liabilities or costs were to materialize, we may not realize the desired benefits from past and future acquisitions,resulting in a negative impact on our results of operations. For example, subsequent to the CDM Acquisition the attrition rate of specialized field techniciansexceeded our projections and, as a result, we incurred unanticipated costs in 2018 to utilize third-party contractors to service our compression units at a greater costthan we would have incurred to compensate employees to perform the same work.We may not be successful in integrating acquisitions into our existing operations within our anticipated time frame, which may result in unforeseenoperational difficulties or diminished financial performance or require a disproportionate amount of our16Table of Contentsmanagement’s attention. In addition, acquired assets may perform at levels below the forecasts used to evaluate their acquisition, due to factors beyond ourcontrol. If the acquired assets perform at levels below the forecasts, then our future results of operations could be negatively impacted.Our ability to fund purchases of additional compression units and complete acquisitions in the future is dependent on our ability to access externalexpansion capital.The Partnership Agreement requires us to distribute all of our available cash to our unitholders (excluding prudent operating reserves). We expect that we willrely primarily upon cash generated by operating activities and, where necessary, borrowings under the Credit Agreement and the issuance of debt and equitysecurities, to fund expansion capital expenditures. However, we may not be able to obtain equity or debt financing on terms favorable to us or at all. To the extentwe are unable to efficiently finance growth through external sources, our ability to maintain or increase the level of distributions on our common units could besignificantly impaired. In addition, because we distribute all of our available cash, excluding prudent operating reserves, we may not grow as quickly as businessesthat are able to reinvest their available cash to expand ongoing operations.There are no limitations in the Partnership Agreement on our ability to issue additional equity securities, including securities ranking senior to the commonunits, subject to certain restrictions in the Partnership Agreement limiting our ability to issue units senior to or pari passu with the Preferred Units. To the extentwe issue additional equity securities, including common units and preferred units, the payment of distributions on those additional securities may increase the riskthat we will be unable to maintain or increase our per common unit distribution level. Similarly, our incurrence of borrowings or other debt to finance our growthstrategy would increase our interest expense, which in turn would decrease our cash available for distribution.Our debt level may limit our flexibility in obtaining additional financing, pursuing other business opportunities and paying distributions.As of December 31, 2019, we had $1.9 billion of total debt, net of amortized deferred financing costs, outstanding comprised of our Credit Agreement andSenior Notes.The Credit Agreement has an aggregate commitment of $1.6 billion (subject to availability under our borrowing base), with a further potential increase of$400 million, and has a maturity date of April 2, 2023. As of December 31, 2019, we had outstanding borrowings under the Credit Agreement of $402.7 million,$1.2 billion of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $484.4 million. Asof December 31, 2019, our leverage ratio under the Credit Agreement was 4.39x. Financial covenants in the Credit Agreement permit a maximum leverage ratio of(i) 5.5 to 1.0 through the end of the fiscal quarter ending December 31, 2019 and (ii) 5.0 to 1.0 thereafter. As of February 13, 2020, we had outstanding borrowingsunder the Credit Agreement of $422.5 million.Our ability to incur additional debt is also subject to limitations in the Credit Agreement, including certain financial covenants. Our level of debt could haveimportant consequences to us, including the following:•our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may not be available orsuch financing may not be available on favorable terms;•we will need a portion of our cash flow to make payments on our indebtedness, reducing the funds that would otherwise be available for operatingactivities, future business opportunities and distributions; and•our debt level will make us more vulnerable than our competitors with less debt to competitive pressures or a downturn in our business or the economygenerally.As of December 31, 2019, we had $725.0 million and $750.0 million aggregate principal amount of Senior Notes 2026 and Senior Notes 2027 outstanding,respectively. The Senior Notes 2026 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. The Senior Notes 2027 accrue interest from March 7, 2019 at the rate of 6.875% per year. Interest on theSenior Notes 2027 is payable semi-annually in arrears on each of March 1 and September 1.Our ability to service our debt will depend upon, among other things, our future financial and operating performance, which will be affected by prevailingeconomic conditions and financial, business, regulatory and other factors, some of which are beyond our control. In addition, our ability to service our debt underthe Credit Agreement could be impacted by market interest rates, as all of our outstanding borrowings under the Credit Agreement are subject to variable interestrates that fluctuate with changes in market interest rates. A substantial increase in the interest rates applicable to our outstanding borrowings could have a material17Table of Contentsnegative impact on our cash available for distribution. If our operating results are not sufficient to service our current or future indebtedness, we could be forced totake actions such as reducing the level of distributions on our common units, curtailing or delaying our business activities, acquisitions, investments or capitalexpenditures, selling assets, restructuring or refinancing our debt or seeking additional equity capital. We may be unable to effect any of these actions on termssatisfactory to us or at all.The terms of the Credit Agreement and the Indentures restrict our current and future operations, particularly our ability to respond to changes or to takecertain actions, may limit our ability to pay distributions and may limit our ability to capitalize on acquisitions and other business opportunities.The Credit Agreement and the Indentures governing the Senior Notes contain a number of restrictive covenants that impose significant operating and financialrestrictions on us and may limit our ability to engage in acts that may be in our long-term best interest, including restrictions on our ability to:•incur additional indebtedness;•pay dividends or make other distributions or repurchase or redeem equityinterests;•prepay, redeem or repurchase certaindebt;•issue certain preferred units or similar equitysecurities;•make investments;•sell assets;•incur liens;•enter into transactions with affiliates;•alter the businesses we conduct;•enter into agreements restricting our subsidiaries’ ability to pay dividends;and•consolidate, merge or sell all or substantially all of ourassets.In addition, the Credit Agreement contains certain operating and financial covenants and requires us to maintain specified financial ratios and satisfy otherfinancial condition tests. Our ability to comply with those covenants and meet those financial ratios and tests can be affected by events beyond our control,including prevailing economic, financial and industry conditions. If market or other conditions deteriorate, our ability to comply with these covenants may beimpaired.A breach of the covenants or restrictions under the Credit Agreement or the Indentures could result in an event of default, in which case a significant portionof our indebtedness may become immediately due and payable and any other debt to which a cross-acceleration or cross-default provision applies may also beaccelerated, our lenders’ commitment to make further loans to us may terminate, and we may be prohibited from making distributions to our unitholders. Wemight not have, or be able to obtain, sufficient funds to make these accelerated payments. If we were unable to repay amounts due and payable under the CreditAgreement, those lenders could proceed against the collateral securing that indebtedness. We may not be able to replace the Credit Agreement, or if we are, anysubsequent replacement of the Credit Agreement or any new indebtedness could be equally or more restrictive.These restrictions may negatively affect our ability to grow in accordance with our strategy. In addition, our financial results, substantial indebtedness andcredit ratings could adversely affect the availability and terms of our financing. Please read Part II, Item 7 “Management’s Discussion and Analysis of FinancialCondition and Results of Operations – Liquidity and Capital Resources – Revolving Credit Facility and – Senior Notes”.The Preferred Units have rights, preferences and privileges that are not held by, and are preferential to the rights of, holders of our common units.The Preferred Units rank senior to all of our other classes or series of equity securities with respect to distribution rights and rights upon liquidation. Thesepreferences could adversely affect the market price for our common units, or could make it more difficult for us to sell our common units in the future.18Table of ContentsIn addition, distributions on the Preferred Units accrue and are cumulative, at the rate of 9.75% per annum on the original issue price, which amounts to aquarterly distribution of $24.375 per Preferred Unit, or $97.50 per Preferred Unit per year. If we do not pay the required distributions on the Preferred Units, wewill be unable to pay distributions on our common units. Additionally, because distributions on the Preferred Units are cumulative, we will have to pay all unpaidaccumulated distributions on the Preferred Units before we can pay any distributions on our common units. Also, because distributions on our common units arenot cumulative, if we do not pay distributions on our common units with respect to any quarter, our common unitholders will not be entitled to receive distributionscovering any prior periods if we later recommence paying distributions on our common units.The Preferred Units are convertible into common units in accordance with the terms of the Partnership Agreement by the holders of the Preferred Units or byus in certain circumstances, beginning April 2, 2021. Our obligation to pay distributions on the Preferred Units, or on the common units issued following theconversion of the Preferred Units, could impact our liquidity and reduce the amount of cash flow available for working capital, capital expenditures, growthopportunities, acquisitions, and other general Partnership purposes. Our obligations to the holders of the Preferred Units could also limit our ability to obtainadditional financing or increase our borrowing costs, which could have an adverse effect on our financial condition. See Note 11 to our consolidated financialstatements in Part II, Item 8 “Financial Statements and Supplementary Data.”Restrictions in the Partnership Agreement related to the Preferred Units may limit our ability to make distributions to our common unitholders and ourability to capitalize on acquisition and other business opportunities.The operating and financial restrictions and covenants in the Partnership Agreement related to the Preferred Units could restrict our ability to finance futureoperations or capital needs or to expand or pursue our business activities. The Partnership Agreement restricts or limits our ability (subject to certain exceptions) to:•pay distributions on any junior securities, including our common units, prior to paying the quarterly distribution payable to the holders of the PreferredUnits, including any previously accrued and unpaid distributions;•issue any securities that rank senior to or pari passu with the Preferred Units; however, we will be able to issue an unlimited number of securities rankingjunior to the Preferred Units, including junior preferred units and additional common units; and•incur Indebtedness (as defined in the Credit Agreement) if, after giving pro forma effect to such incurrence, the Leverage Ratio (as defined in the CreditAgreement) determined as of the last day of the most recently ended fiscal quarter would exceed 6.5x, subject to certain exceptions.A prolonged downturn in the economic environment could cause an impairment of goodwill or other intangible assets and reduce our earnings.We have recorded $619.4 million of goodwill and $363.2 million of other intangible assets, net, as of December 31, 2019. Goodwill is recorded when thepurchase price of a business exceeds the fair market value of the tangible and separately measurable intangible net assets. Generally accepted accounting principlesof the United States (“GAAP”) requires us to test goodwill for impairment on an annual basis or when events or circumstances occur indicating that goodwill mightbe impaired. Any event that causes a reduction in demand for our services could result in a reduction of our estimates of future cash flows and growth rates in ourbusiness. These events could cause us to record impairments of goodwill or other intangible assets.If we determine that any of our goodwill or other intangible assets are impaired, we will be required to take an immediate charge to earnings with acorresponding reduction of partners’ capital resulting in an increase in balance sheet leverage as measured by debt to total capitalization. For example, for the yearended December 31, 2017, the USA Compression Predecessor recognized a $223.0 million impairment of goodwill. See Note 6 to our consolidated financialstatements in Part II, Item 8 (“Financial Statements and Supplementary Data”) for information regarding goodwill impairment.Impairment in the carrying value of long-lived assets could reduce our earnings.We have a significant number of long-lived assets on our consolidated balance sheet. Under GAAP, we are required to review our long-lived assets forimpairment when events or circumstances indicate that the carrying value of such assets may not be recoverable or such assets will no longer be utilized in theoperating fleet. 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 andeventual disposition of the asset. If business conditions or other factors cause the expected undiscounted cash flows to decline, we may be required to record non-cash impairment charges. Events and conditions that could result in impairment in the value of our long-lived assets include changes in the industry in which weoperate, competition, advances in technology, adverse changes in the regulatory environment, or other factors leading19Table of Contentsto a reduction in our expected long-term profitability. For example, for the years ended the years ended December 31, 2019 and 2018, we evaluated the futuredeployment of our idle fleet under then-current market conditions and determined to retire and re-utilize key components of 33 and 103 compressor units,respectively, or approximately 11,000 and 33,000 horsepower, respectively, that were previously used to provide services in our business. As a result, we recorded$5.9 million and $8.7 million in impairment of compression equipment for the years ended December 31, 2019 and 2018, respectively.Our ability to manage and grow our business effectively may be adversely affected if we lose key management or operational personnel.We depend on the continuing efforts of our executive officers and the departure of any of our executive officers could have a significant negative effect on ourbusiness, operating results, financial condition and on our ability to compete effectively in the marketplace.Additionally, our ability to hire, train and retain qualified personnel will continue to be important and could become more challenging as we grow and to theextent energy industry market conditions are competitive. When general industry conditions are favorable, the competition for experienced operational and fieldtechnicians increases as other energy and manufacturing companies’ needs for the same personnel increases. Our ability to grow or even to continue our currentlevel of service to our current customers could be adversely impacted if we are unable to successfully hire, train and retain these important personnel.We depend on a limited number of suppliers and are vulnerable to product shortages and price increases, which could have a negative impact on ourresults of operations.The substantial majority of the components for our natural gas compression equipment are supplied by Caterpillar Inc., Cummins Inc. and Arrow EngineCompany for engines, Air-X-Changers and Alfa Laval (US) for coolers, and Ariel Corporation, GE Oil & Gas Gemini products and Arrow Engine Company forcompressor frames and cylinders. Our reliance on these suppliers involves several risks, including price increases and a potential inability to obtain an adequatesupply of required components in a timely manner. We also rely primarily on four vendors, A G Equipment Company, Alegacy Equipment, LLC, StandardEquipment Corp. and Genis Holdings LLC, to package and assemble our compression units. We do not have long-term contracts with these suppliers or packagers,and a partial or complete loss of any of these sources could have a negative impact on our results of operations and could damage our customer relationships. Someof these suppliers manufacture the components we purchase in a single facility, and any damage to that facility could lead to significant delays in delivery ofcompleted compression units to us. We are subject to substantial environmental regulation, and changes in these regulations could increase our costs or liabilities.We are subject to stringent and complex federal, state and local laws and regulations, including laws and regulations regarding the discharge of materials intothe environment, emissions controls and other environmental protection and occupational health and safety concerns, as discussed in detail in Item 1 “Business –Our Operations – Environmental and Safety Regulations”. Environmental laws and regulations may, in certain circumstances, impose strict liability forenvironmental contamination, which may render us liable for remediation costs, natural resource damages and other damages as a result of our conduct that waslawful at the time it occurred or the conduct of, or conditions caused by, prior owners or operators or other third parties. In addition, where contamination may bepresent, it is not uncommon for neighboring land owners and other third parties to file claims for personal injury, property damage and recovery of response costs.Remediation costs and other damages arising as a result of environmental laws and regulations, and costs associated with new information, changes in existingenvironmental laws and regulations or the adoption of new environmental laws and regulations could be substantial and could negatively impact our financialcondition or results of operations. Moreover, failure to comply with these environmental laws and regulations may result in the imposition of administrative, civiland criminal penalties and the issuance of injunctions delaying or prohibiting operations.We conduct operations in a wide variety of locations across the continental U.S. These operations require U.S. federal, state or local environmental permits orother authorizations. Our operations may require new or amended facility permits or licenses from time to time with respect to storm water discharges, wastehandling or air emissions relating to equipment operations, which subject us to new or revised permitting conditions that may be onerous or costly to comply with.Additionally, the operation of compression units may require individual air permits or general authorizations to operate under various air regulatory programsestablished by rule or regulation. These permits and authorizations frequently contain numerous compliance requirements, including monitoring and reportingobligations and operational restrictions, such as emissions limits. Given the wide variety of locations in which we operate, and the numerous environmental permitsand other authorizations that are applicable to our operations, we may occasionally identify or be notified of technical violations of certain requirements existingunder various permits or other authorizations. We could be subject to penalties for any noncompliance in the future.20Table of ContentsAdditionally, some states have also passed legislation or regulations regarding hydraulic fracturing. For example, in 2019, Colorado passed Senate Bill 181,which delegates authority to local governments to regulate oil and gas activities and requires the Colorado Oil and Gas Conservation Commission to minimizeemissions of methane and other air contaminants. Some local communities have adopted additional restrictions for oil and gas activities, such as requiring greatersetbacks, and some groups are petitioning local governments to ban hydraulic fracturing. If additional regulatory measures are adopted, customers in Coloradocould experience delays, limitations, or prohibitions on their activities. Such delays, limitations, or prohibitions could result in decreased demand for our services.In our business, we routinely deal with natural gas, oil and other petroleum products at our worksites. Hydrocarbons or other hazardous substances or wastesmay have been disposed or released on, under or from properties used by us to provide compression services or inactive compression unit storage or on or underother locations where such substances or wastes have been taken for disposal. These properties may be subject to investigatory, remediation and monitoringrequirements under federal, state and local environmental laws and regulations.The modification or interpretation of existing environmental laws or regulations, the more vigorous enforcement of existing environmental laws or regulations,or the adoption of new environmental laws or regulations may also negatively impact oil and natural gas exploration and production, gathering and pipelinecompanies, including our customers, which in turn could have a negative impact on us.New regulations, proposed regulations and proposed modifications to existing regulations under the Clean Air Act, if implemented, could result inincreased compliance costs.New regulations or proposed modifications to existing regulations under the Clean Air Act (“CAA”), as discussed in detail in Item 1 “Business – OurOperations – Environmental and Safety Regulations”, may lead to adverse impacts on our business, financial condition, results of operations, and cash availablefor distribution. For example, in 2015, the EPA finalized a rule strengthening the primary and secondary National Ambient Air Quality Standards (“NAAQS”) forground level ozone, both of which are 8-hour concentration standards of 70 parts per billion. After the EPA revises a NAAQS standard, the states are expected toestablish revised attainment/non-attainment regions. State implementation of the revised NAAQS could result in stricter permitting requirements, delay or prohibitour customers’ ability to obtain such permits, and result in increased expenditures for pollution control equipment, which could negatively impact our customers’operations, increase the cost of additions to property, plant, and equipment, and negatively impact our business.In 2012, the EPA finalized rules that establish new air emissions controls for oil and natural gas production and natural gas processing operations.Specifically, the EPA’s rule package included New Source Performance Standards to address emissions of sulfur dioxide and volatile organic compounds(“VOCs”) and a separate set of emissions standards to address hazardous air pollutants frequently associated with oil and natural gas production and processingactivities. The rules established specific new requirements regarding emissions from compressors and controllers at natural gas processing plants, dehydrators,storage tanks and other production equipment as well as the first federal air standards for natural gas wells that are hydraulically fractured. In June 2016, the EPAtook steps to expand on these regulations when it published New Source Performance Standards, known as Subpart OOOOa, that require certain new, modified orreconstructed facilities in the oil and natural gas sector to reduce methane gas and VOC emissions. These Subpart OOOOa standards would expand the 2012 NewSource Performance Standards by using certain equipment-specific emissions control practices, requiring additional controls for pneumatic controllers and pumpsas well as compressors, and imposing leak detection and repair requirements for natural gas compressor and booster stations. However, the EPA announced inApril 2017 that it intended to reconsider certain aspects of the 2016 New Source Performance Standards, and in May 2017, the EPA issued an administrative stayof key provisions of the rule, but was promptly ordered by the D.C. Circuit to implement the rule. The EPA also proposed 60-day and two-year stays of certainprovisions in June 2017 and published a Notice of Data Availability in November 2017 seeking comment and providing clarification regarding the agency’s legalauthority to stay the rule. In March 2018, the EPA finalized narrow amendments to the rule, and in October 2018, the EPA proposed further reconsiderationamendments to the rule. Among other things, these amendments would alter fugitive emissions requirements, monitoring frequencies and well site pneumaticpump standards. In September 2019, the EPA published a proposed rulemaking amending the June 2016 regulations that, among other things, would removesources in the transmission and storage segment from the oil and natural gas source category and rescind the methane-specific requirements applicable to sourcesin the production and processing segments of the industry. As an alternative, EPA also proposed to rescind the methane-specific requirements that apply to allsources in the oil and natural gas industry, without removing the transmission and storage sources from the current source category. Under either alternative, EPAplans to retain emissions limits for volatile organic compounds. The EPA proposed rulemaking indicates that the controls to reduce volatile organic compoundemissions also reduce methane at the same time, so separate methane limitations for these segments of the industry are redundant. Whether these proposedstandards may become implemented, on what date and exactly what they will require is unknown at this time.21Table of ContentsDepending on whether the EPA finalizes these further amendments or promulgates any additional regulation of air emissions from the oil and gas sector couldresult in increased expenditures for pollution control equipment, which could impact our customers’ operations and negatively impact our business.Climate change legislation, regulatory initiatives, and litigation could result in increased compliance costs and restrictions on our customers’ operations.Climate change continues to attract considerable public and scientific attention. Methane, a primary component of natural gas, and carbon dioxide, abyproduct of the burning of natural gas, are examples of greenhouse gases (“GHGs”). In recent years, the U.S. Congress has considered legislation to reduce GHGemissions. It presently appears unlikely that comprehensive climate legislation will be passed in the near future, although energy legislation and other initiativesare expected to be proposed that may be relevant to GHG emissions issues. For example, such initiatives could include a carbon tax or cap and trade program.Further, although Congress has not passed such legislation, many states have begun to address GHG emissions, primarily through the planned development ofemissions inventories or regional GHG cap and trade programs. Depending on the particular program, we could be required to control GHG emissions or topurchase and surrender allowances for GHG emissions resulting from our operations.Federal and possibly state governments may impose significant and potentially draconian restrictions on fossil-fuel exploration, production and use if pledgesmade by certain candidates seeking various political offices were enacted into law. Some proposals include bans on hydraulic fracturing of oil and gas wells, banson new leases for production of minerals on federal properties, and imposing restrictive requirements on new pipeline infrastructure or fossil-fuel export facilities.Other energy legislation and initiatives could include a carbon tax or cap and trade program. Further, although Congress has not passed such legislation, almosthalf of the states have begun to address GHG emissions, primarily through the planned development of emissions inventories or regional GHG cap and tradeprograms. Depending on the particular program, we could be required to control GHG emissions or to purchase and surrender allowances for GHG emissionsresulting from our operations. Litigation risks are also increasing, as a number of cities, local governments and other plaintiffs have sued companies engaged in theexploration and production of fossil fuels in state and federal courts, alleging various legal theories to recover for the impacts of alleged global warming effects,such as rising sea levels. Many of these suits allege that the companies have been aware of the adverse effects of climate change for some time but defrauded theirinvestors by failing to adequately disclose those impacts. Although a number of these lawsuits have been dismissed, others remain pending and the outcome ofthese cases remains difficult to predict.Independent of Congress, and as discussed in detail in Item 1 “Business – Our Operations – Environmental and Safety Regulations”, the EPA undertook toadopt regulations controlling GHG emissions under its existing CAA authority. For example, in 2015, the EPA published standards of performance for GHGemissions from new power plants. The final rule establishes a performance standard for integrated gasification combined cycled units and utility boilers based onthe use of the best system of emissions reduction that the EPA has determined has been adequately demonstrated for each type of unit. The rule also sets limits forstationary natural gas combustion turbines based on the use of natural gas combined cycle technology. The EPA also promulgated the Clean Power Plan rule(“CPP”), which is intended to reduce carbon emissions from existing power plants by 32 percent from 2005 levels by 2030. In February 2016, the U.S. SupremeCourt granted a stay of the implementation of the CPP, which will remain in effect throughout the pendency of the appeals process, including at the United StatesCourt of Appeals for the D.C. Circuit and the Supreme Court through any certiorari petition that may be granted. The stay suspends the rule, including therequirement that states must start submitting implementation plans. It is not yet clear how the courts will ultimately rule on the legality of the CPP. Additionally, inOctober 2017, the EPA proposed to repeal the CPP, and in August 2018, the EPA proposed the Affordable Clean Energy rule (“ACE”) to replace the CPP. If theeffort to replace the CPP with the ACE is unsuccessful and rules similar to the CPP are upheld to control GHG emissions from electric utility generating units,demand for the oil and natural gas our customers produce may decrease.Although it is not currently possible to predict with specificity how any proposed or future GHG legislation, regulation, agreements or initiatives will impactour business, any legislation or regulation of GHG emissions that may be imposed in areas in which we conduct business or on the assets we operate could result inincreased compliance or operating costs or additional operating restrictions or reduced demand for our services, and could have a material adverse effect on ourbusiness, financial condition and results of operations.Finally, it should be noted that some scientists have concluded that increasing concentrations of GHG in Earth’s atmosphere may produce climate changesthat have significant weather-related effects, such as increased frequency and severity of storms, droughts, floods and other climatic events. If any of those effectswere to occur, they could have an adverse effect on our assets and operations. Also, recent activism directed at shifting funding away from companies withenergy-related assets could result in a reduction of funding for the energy sector overall, which could have an adverse effect on our ability to obtain externalfinancing.22Table of ContentsIncreased regulation of hydraulic fracturing could result in reductions of, or delays in, natural gas production by our customers, which could adverselyimpact our revenue.A significant portion of our customers’ natural gas production is developed from unconventional sources that require hydraulic fracturing as part of thecompletion process. Hydraulic fracturing involves the injection of water, sand and chemicals under pressure into the rock formation to stimulate gas production.Legislation to amend the Safe Drinking Water Act (“SDWA”) to repeal the exemption for hydraulic fracturing from the definition of “underground injection” andrequire federal permitting and regulatory control of hydraulic fracturing, as well as legislative proposals to require disclosure of the chemical constituents of thefluids used in the fracturing process, have been proposed and the U.S. Congress continues to consider legislation to amend the SDWA. Additionally, concern overthe threat of climate change has resulted in the making of pledges by certain candidates seeking the office of the President of the United States in 2020 to banhydraulic fracturing of oil and natural gas wells.Scrutiny of hydraulic fracturing activities also continues in other ways, with the EPA having commenced a multi-year study of the potential environmentalimpacts of hydraulic fracturing. In December 2016, the EPA released its final report on the potential impacts of hydraulic fracturing on drinking water resources.The final report concluded that “water cycle” activities associated with hydraulic fracturing may impact drinking water resources “under some circumstances,”noting that the following hydraulic fracturing water cycle activities and local- or regional-scale factors are more likely than others to result in more frequent ormore severe impacts: water withdrawals for fracturing in times or areas of low water availability; surface spills during the management of fracturing fluids,chemicals or produced water; injection of fracturing fluids into wells with inadequate mechanical integrity; injection of fracturing fluids directly into groundwaterresources; discharge of inadequately treated fracturing wastewater to surface waters; and disposal or storage of fracturing wastewater in unlined pits.In addition to the EPA, the Bureau of Land Management (“BLM”) also has also promulgated rules to regulate hydraulic fracturing. In 2015, the BLMpromulgated new requirements relating to well construction, water management, and chemical disclosure for companies drilling on federal and tribal land, butsubsequently finalized a rule in December 2017 rescinding the 2015 rule. This rescission has been challenged, and that litigation is ongoing. If this rescission is notupheld, it could increase the costs of operation for our customers who operate on BLM land, and negatively impact our business. Additionally, on November 15,2016, the BLM also finalized a rule to reduce the flaring, venting and leaking of methane from oil and gas operations on federal and Indian lands. The VentingRule requires operators to use certain technologies and equipment to reduce flaring and to periodically inspect their operations for leaks. The Venting Rule alsospecifies when operators owe the government royalties for flared gas. In December 2017, BLM finalized a decision to delay implementation of key requirements inthe Venting Rule for one year. The agency subsequently finalized a rule in September 2018 to revise the 2016 Venting rule by rescinding certain requirements, suchas the requirement to use certain technologies and equipment, as well as the leak detection and repair requirement. The Revised Venting Rule also specifies thatthe BLM will defer to the appropriate State or tribal authorities in determining whether royalties are owed for flared gas. Challenges to the Venting Rule and theRevised Venting Rule are pending in court. If the Revised Venting Rule is not upheld, and the Venting Rule is fully implemented, it could increase the costs ofoperations for our customers who operate on BLM land, and in turn negatively impact our business.State and federal regulatory agencies have also recently focused on a possible connection between the operation of injection wells used for oil and gas wastedisposal and seismic activity. Similar concerns have been raised that hydraulic fracturing may also contribute to seismic activity. When caused by human activity,such events are called induced seismicity. Developing research suggests that the link between seismic activity and wastewater disposal may vary by region, andthat only a very small fraction of the tens of thousands of injection wells have been suspected to be, or have been, the likely cause of induced seismicity. In March2016, the United States Geological Survey identified six states with the most significant hazards from induced seismicity, including Oklahoma, Kansas, Texas,Colorado, New Mexico, and Arkansas. In light of these concerns, some state regulatory agencies have modified their regulations or issued orders to addressinduced seismicity. Increased regulation and attention given to induced seismicity could lead to greater opposition to, and litigation concerning, oil and gasactivities utilizing hydraulic fracturing or injection wells for waste disposal, which could indirectly impact our business, financial condition and results ofoperations. In addition, these concerns may give rise to private tort suits against our customers from individuals who claim they are adversely impacted by seismicactivity they allege was induced. Such claims or actions could result in liability to our customers for property damage, exposure to waste and other hazardousmaterials, nuisance or personal injuries, and require our customers to expend additional resources or incur substantial costs or losses. This could in turn adverselyaffect the demand for our services.We cannot predict the future of any such legislation or tort liability. If additional levels of regulation, restrictions and permits were required through theadoption of new laws and regulations at the federal or state level or the development of new interpretations of those requirements by the agencies that issue therequired permits, that could lead to operational delays, increased operating costs and process prohibitions that could reduce demand for our compression services,which would materially adversely affect our revenue and results of operations.23Table of ContentsThe CDM Acquisition could expose us to additional unknown and contingent liabilities.The CDM Acquisition could expose us to additional unknown and contingent liabilities. We performed due diligence in connection with the CDM Acquisitionand attempted to verify the representations made by ETO in connection therewith, but there may be unknown and contingent liabilities of which we are currentlyunaware. ETO has agreed to indemnify us for losses or claims relating to the operation of the business or otherwise only to a limited extent and for a limited periodof time, and certain of ETO’s indemnification obligations lapsed in late 2019. There is a risk that we could ultimately be liable for obligations relating to the CDMAcquisition for which indemnification is not available, which could materially adversely affect our business, results of operations and cash flow.We do not insure against all potential losses and could be seriously harmed by unexpected liabilities.Our operations are subject to inherent risks such as equipment defects, malfunctions and failures, and natural disasters that can result in uncontrollable flows ofgas or well fluids, fires and explosions. These risks could expose us to substantial liability for personal injury, death, property damage, pollution and otherenvironmental damages. Our insurance may be inadequate to cover our liabilities. Further, insurance covering the risks we face or in the amounts we desire maynot be available in the future or, if available, the premiums may not be commercially justifiable. If we were to incur substantial liability and such damages were notcovered by insurance or were in excess of policy limits, or if we were to incur liability at a time when we are not able to obtain liability insurance, our business,results of operations and financial condition could be adversely affected.Cybersecurity breaches and other disruptions of our information systems could compromise our information and operations and expose us to liability,which would cause our business and reputation to suffer.We rely on our information technology infrastructure to process, transmit and store electronic information critical to our business activities. In recent years,there has been a rise in the number of cyberattacks on other companies’ network and information systems by both state-sponsored and criminal organizations, andas a result, the risks associated with such an event continue to increase. A significant failure, compromise, breach or interruption of our information systems couldresult in a disruption of our operations, customer dissatisfaction, damage to our reputation, a loss of customers or revenues and potential regulatory fines. If anysuch failure, interruption or similar event results in improper disclosure of information maintained in our information systems and networks or those of ourcustomers, suppliers or vendors, including personnel, customer, pricing and other sensitive information, we could also be subject to liability under relevantcontractual obligations and laws and regulations protecting personal data and privacy. Our financial results could also be adversely affected if our informationsystems are breached or an employee causes our information systems to fail, either as a result of inadvertent error or by deliberately tampering with ormanipulating such systems.Terrorist attacks, the threat of terrorist attacks or other sustained military campaigns may adversely impact our results of operations.The long-term impact of terrorist attacks and the magnitude of the threat of future terrorist attacks on the energy industry in general and on us in particular arenot known at this time. Uncertainty surrounding sustained military campaigns may affect our operations in unpredictable ways, including disruptions of crude oiland natural gas supplies and markets for crude oil, natural gas and natural gas liquids and the possibility that infrastructure facilities could be direct targets of, orindirect casualties of, an act of terror. Changes in the insurance markets attributable to terrorist attacks may make insurance against such attacks more difficult forus to obtain, if we choose to do so. Moreover, the insurance that may be available to us may be significantly more expensive than our existing insurance coverage.Instability in the financial markets resulting from terrorism or war could also negatively affect our ability to raise capital.If we fail to develop or maintain an effective system of internal controls, we may not be able to report our financial results accurately or prevent fraud,which would likely have a negative impact on the market price of our common units.Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and to operate successfully as a publicly traded partnership.Although we continuously evaluate the effectiveness of and improve upon our internal controls, our efforts to develop and maintain our internal controls may notbe successful, and we may be unable to maintain effective controls over our financial processes and reporting in the future or to comply with our obligations underSection 404 of the Sarbanes-Oxley Act of 2002 (“Section 404”). For example, Section 404 requires us to, among other things, review and report annually on theeffectiveness of our internal control over financial reporting. In addition, our independent registered public accountants are required to assess the effectiveness ofour internal control over financial reporting since we ceased to be an emerging growth company under the Jumpstart Our Business Startups Act (the “JOBS Act”)on December 31, 2018.24Table of ContentsAny failure to develop, implement or maintain effective internal controls or to improve our internal controls could harm our operating results or cause us tofail to meet our reporting obligations. Given the difficulties inherent in the design and operation of internal controls over financial reporting, we can provide noassurance as to our independent registered public accounting firm’s conclusions about the effectiveness of our internal controls, and we may incur significant costsin our efforts to comply with Section 404. Ineffective internal controls will subject us to regulatory scrutiny and may result in a loss of confidence in our reportedfinancial information, which could have an adverse effect on our business and would likely have a negative effect on the trading price of our common units.Risks Inherent in an Investment in UsHolders of our common units have limited voting rights and are not entitled to elect the General Partner or its directors.Unlike the holders of common stock in a corporation, our common unitholders have only limited voting rights on matters affecting our business and, therefore,limited ability to influence management’s decisions regarding our business. Common unitholders have no right to elect the General Partner or the board ofdirectors of the General Partner (the “Board”). ETO is the sole member of the General Partner and has the right to appoint the majority of the members of theBoard, including all but one of its independent directors. Also, pursuant to that certain Board Representation Agreement entered into by us, the General Partner, ETLP and EIG Veteran Equity Aggregator, L.P. (along with its affiliated funds, “EIG”) in connection with our private placement of Preferred Units and Warrants toEIG, 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 than5% of the Partnership’s outstanding common units in the aggregate (taking into account the common units that would be issuable upon conversion of the PreferredUnits and exercise of the Warrants).If our common unitholders are dissatisfied with the General Partner’s performance, they have little ability to remove the General Partner. As a result of theselimitations, the price of our common units may decline because of the absence or reduction of a takeover premium in the trading price. Furthermore, thePartnership Agreement contains provisions limiting the ability of common unitholders to call meetings or to obtain information about our operations, as well asother provisions limiting our common unitholders’ ability to influence the manner or direction of management.ETO owns and controls the General Partner, and the General Partner has sole responsibility for conducting our business and managing our operations.The General Partner and its affiliates, including ETO, have conflicts of interest with us and limited fiduciary duties, and they may favor their own interests tothe detriment of us and our unitholders.ETO owns and controls the General Partner and appointed all of the officers and a majority of the directors of the General Partner, some of whom are alsoofficers and directors of ETO. Although the General Partner has a fiduciary duty to manage us in a manner that is beneficial to us and our unitholders, the directorsand officers of the General Partner also have a fiduciary duty to manage the General Partner in a manner that is beneficial to its owner. Conflicts of interest willarise between the General Partner and its owner, on the one hand, and us and our unitholders, on the other hand. In resolving these conflicts of interest, the GeneralPartner may favor its own interests and the interests of its owner over our interests and the interests of our unitholders. These conflicts include the followingsituations, among others:•neither the Partnership Agreement nor any other agreement requires ETO to pursue a business strategy that favorsus;•ETO and its affiliates are not prohibited from engaging in businesses or activities that are in direct competition with us or from offering businessopportunities or selling assets to our competitors;•the General Partner is allowed to take into account the interests of parties other than us, such as its owner, in resolving conflicts ofinterest;•the Partnership Agreement limits the liability of and reduces the fiduciary duties owed by the General Partner, and also restricts the remedies available toour unitholders for actions that, without such limitations, might constitute breaches of fiduciary duty;•except in limited circumstances, the General Partner has the power and authority to conduct our business without unitholderapproval;•the General Partner determines the amount and timing of asset purchases and sales, borrowings, issuance of additional partnership interests and thecreation, reduction or increase of reserves, each of which can affect the amount of cash that is distributed to our unitholders;25Table of Contents•the General Partner determines the amount and timing of any capital expenditures and whether a capital expenditure is classified as a maintenance capitalexpenditure, which reduces operating surplus, or an expansion capital expenditure, which does not reduce operating surplus. This determination can affectthe amount of cash that is distributed to our unitholders;•the General Partner determines which costs it incurs are reimbursable by us;•the General Partner may cause us to borrow funds in order to permit the payment of cashdistributions;•the Partnership Agreement permits us to classify up to $36.6 million as operating surplus, even if it is generated from asset sales, non-working capitalborrowings or other sources that would otherwise constitute capital surplus;•the Partnership Agreement does not restrict the General Partner from causing us to pay it or its affiliates for any services rendered to us or entering intoadditional contractual arrangements with any of these entities on our behalf;•the General Partner currently limits, and intends to continue limiting, its liability for our contractual and otherobligations;•the General Partner may exercise its right to call and purchase all of our common units not owned by it and its affiliates if together those entities at anytime own more than 80% of our common units;•the General Partner controls the enforcement of the obligations that it and its affiliates owe to us;and•the General Partner decides whether to retain separate counsel, accountants or others to perform services forus.The General Partner’s liability for our obligations is limited.The General Partner has included, and will continue to include, provisions in its and our contractual arrangements that limit its liability under such contractualarrangements so that the counterparties to such arrangements have recourse only against our assets, and not against the General Partner or its assets. The GeneralPartner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to it. The Partnership Agreement provides that any action taken bythe General Partner to limit its liability is not a breach of the General Partner’s fiduciary duties, even if we could have obtained more favorable terms without suchlimitation on liability. In addition, we are obligated to reimburse or indemnify the General Partner to the extent that it incurs obligations on our behalf. Any suchreimbursement or indemnification payments would reduce our amount of cash otherwise available for distribution.The Partnership Agreement limits the General Partner’s fiduciary duties to our unitholders.The Partnership Agreement contains provisions that modify and reduce the fiduciary standards to which the General Partner would otherwise be held by statefiduciary duty law. For example, the Partnership Agreement permits the General Partner to make a number of decisions in its individual capacity, as opposed to itscapacity as the General Partner, or otherwise free of fiduciary duties to us and our unitholders. This entitles the General Partner to consider only the interests andfactors that it desires and relieves it of any duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limitedpartners. Examples of decisions that the General Partner may make in its individual capacity include:•how to allocate business opportunities among us and itsaffiliates;•whether to exercise its limited callright;•how to exercise its voting rights with respect to the common units it owns;and•whether or not to consent to any merger or consolidation of the Partnership or amendment to the Partnership Agreement.By purchasing a unit, a unitholder agrees to become bound by the provisions of the Partnership Agreement, including the provisions discussed above.Even if holders of our common units are dissatisfied, they currently cannot remove the General Partner without ETO’s consent.Common unitholders are currently unable to remove the General Partner because the General Partner and its affiliates own sufficient number of our commonunits to prevent its removal. The vote of the holders of at least 662/3% of all outstanding common units is required to remove the General Partner, and ETOcurrently owns over 331/3% of our outstanding common units.26Table of ContentsThe Partnership Agreement restricts the remedies available to holders of our common units for actions taken by the General Partner that might otherwiseconstitute breaches of fiduciary duty.The Partnership Agreement contains provisions that restrict the remedies available to common unitholders for actions taken by the General Partner that mightotherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, the Partnership Agreement:•provides that whenever the General Partner makes a determination or takes, or declines to take, any other action in its capacity as the General Partner, theGeneral Partner is required to make such determination, or take or decline to take such other action, in good faith, and will not be subject to any higherstandard imposed by the Partnership Agreement, Delaware law, or any other law, rule or regulation, or at equity;•provides that the General Partner will not have any liability to us or our unitholders for decisions made in its capacity as general partner so long as suchdecisions are made in good faith, meaning that it believed that the decisions were in the best interest of the Partnership;•provides that the General Partner and its officers and directors will not be liable for monetary damages to us, our limited partners or their assigneesresulting from any act or omission unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determiningthat the General Partner or its officers and directors, as the case may be, acted in bad faith or engaged in fraud or willful misconduct or, in the case of acriminal matter, acted with knowledge that the conduct was criminal; and•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 ifa 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 suchapproval;(b)approved by the vote of a majority of our outstanding common units, excluding any common units owned by the General Partner and itsaffiliates;(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 maybe particularly favorable or advantageous to us.In a situation involving a transaction with an affiliate or a conflict of interest, any determination by the General Partner must be made in good faith. If anaffiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the conflicts committee and the Board determines thatthe resolution or course of action taken with respect to the affiliate transaction or 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.The Partnership Agreement restricts the voting rights of unitholders owning 20% or more of our common units.Common unitholders’ voting rights are further restricted by a provision of the Partnership Agreement providing that any units held by a person or group thatowns 20% or more of such class of units then outstanding, other than, with respect to our common units, the General Partner, its affiliates, their direct transfereesand their indirect transferees approved by the General Partner (which approval may be granted in its sole discretion) and persons who acquired such common unitswith the prior approval of the General Partner, cannot vote on any matter.The general partner interest or the control of the General Partner may be transferred to a third party without unitholder consent.The General Partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent ofthe common unitholders. Furthermore, the Partnership Agreement does not restrict the ability of ETO to transfer all or a portion of its ownership interest in theGeneral Partner to a third party. The new owner of the General Partner would then be in a position to replace the majority of the Board, and all of the officers, ofthe General Partner with its own designees and thereby exert significant control over the decisions made by the Board and the officers of the General Partner.27Table of ContentsAn increase in interest rates may cause the market price of our common units to decline.The market price of master limited partnership units, like other yield-oriented securities, may be affected by, among other factors, implied distribution yield.The distribution yield is often used by investors to compare and rank yield-oriented securities for investment decision-making purposes. Therefore, increases ordecreases in interest rates may affect whether or not certain investors decide to invest in master limited partnership units, including ours, and a rising interest rateenvironment could have an adverse impact on our common unit price and impair our ability to issue additional equity or incur debt to fund growth or for otherpurposes, including distributions.We may issue additional limited partner interests without the approval of the common unitholders, which would dilute the common unitholders’ existingownership interests and may increase the risk that we will not have sufficient available cash to maintain or increase our per common unit distribution level.The Partnership Agreement does not limit the number or timing of additional limited partner interests that we may issue, including limited partner intereststhat are convertible into our common units, without the approval of our common unitholders.If a substantial portion of the Preferred Units are converted into common units, common unitholders could experience significant dilution. Furthermore, ifholders of such converted Preferred Units were to dispose of a substantial portion of these common units in the public market, whether in a single transaction orseries of transactions, it could adversely affect the market price of our common units. In addition, these sales, or the possibility that these sales may occur, couldmake it more difficult for us to sell our common units in the future.Our issuance of additional common units, including pursuant to our Distribution Reinvestment Plan (“DRIP”), or other equity securities of equal or seniorrank, such as additional preferred units, will have the following effects:•our existing common unitholders’ proportionate ownership interest in us willdecrease;•our amount of cash available for distribution to common unitholders maydecrease;•our ratio of taxable income to distributions mayincrease;•the relative voting strength of each previously outstanding common unit may be diminished;and•the market price of our common units maydecline.ETO and the holders of the Preferred Units may sell our common units in the public or private markets, and such sales could have an adverse impact onthe trading price of our common units.As of December 31, 2019, ETO beneficially owns an aggregate of 46,056,228 common units in us. We have granted certain registration rights to ETO and itsaffiliates with respect to any common units they own, and have filed a registration statement with the SEC for the benefit of the holders of the Preferred Units withrespect to any common units they may own upon conversion of the Preferred Units or exercise of the Warrants. The sale of these common units in the public orprivate markets could have an adverse impact on the price of our common units or on any trading market that may develop. The General Partner has a call right that may require you to sell your common units at an undesirable time or price.If at any time the General Partner and its affiliates own more than 80% of our outstanding common units, the General Partner will have the right, but not theobligation, which it may assign to any of its affiliates or to us, to acquire all, but not less than all, of our common units held by unaffiliated persons at a price that isnot less than their then-current market price, as calculated pursuant to the terms of the Partnership Agreement. As a result, you may be required to sell yourcommon units at an undesirable time or price. You may also incur a tax liability upon a sale of your common units. As of December 31, 2019, the General Partnerand its affiliates (including ETO), beneficially own an aggregate of approximately 48% of our outstanding common units.Your liability may not be limited if a court finds that unitholder action constitutes control of our business.A general partner of a partnership generally has unlimited liability for the obligations of the partnership, except for those contractual obligations of thepartnership that are expressly made without recourse to the general partner. The Partnership is organized under Delaware law and conducts business in a number ofother states, and in some of those states, the limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have notbeen clearly established.28Table of ContentsYou could be liable for any and all of our obligations as if you were a general partner if a court or governmental agency were to determine that:•we were conducting business in a state but had not complied with that particular state’s partnership statute;or•your right to act with other unitholders to remove or replace the General Partner, to approve some amendments to the Partnership Agreement or to takeother actions under the Partnership Agreement constitute “control” of our business.Unitholders may have liability to repay distributions that were wrongfully distributed to them.Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the DelawareRevised Uniform Limited Partnership Act (the “Delaware Act”), we may not make a distribution if the distribution would cause our liabilities to exceed the fairvalue of our assets. The Delaware Act provides that for a period of three years from the date of an impermissible distribution, limited partners who received thedistribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount.Liabilities to partners on account of their interest in the Partnership and liabilities that are nonrecourse to the Partnership are not counted for purposes ofdetermining whether a distribution is permissible.Our Partnership Agreement designates the Court of Chancery of the State of Delaware as the exclusive forum for certain types of actions and proceedingsthat may be initiated by our unitholders, which would limit our unitholders’ ability to choose the judicial forum for disputes with us or our general partner’sdirectors, officers or other employees.Our Partnership Agreement provides that, with certain limited exceptions, the Court of Chancery of the State of Delaware (or, if such court does not havesubject matter jurisdiction thereof, any other court located in the State of Delaware with subject matter jurisdiction) shall be the exclusive forum for any claims,suits, actions or proceedings (i) arising out of or relating in any way to the Partnership Agreement (including any claims, suits or actions to interpret, apply orenforce the provisions of the Partnership Agreement), any partnership interest or the duties, obligations or liabilities among limited partners or of limited partners,or the rights or powers of, or restrictions on, the limited partners or us, (ii) asserting a claim arising out of any other instrument, document, agreement or certificatecontemplated by any provision of the Delaware Act relating to the Partnership or the Partnership Agreement, (iii) asserting a claim against us arising pursuant toany provision of the Delaware Act or (iv) arising out of the federal securities laws of the U.S. or securities or antifraud laws of any governmental authority.The exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any otherclaim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of theExchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulationsthereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty orliability created by the Securities Act or the rules and regulations thereunder.The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or similar governing documents has been challengedin legal proceedings, and it is possible that a court could find the choice of forum provisions contained in our Partnership Agreement to be inapplicable orunenforceable, including with respect to claims arising under the U.S. federal securities laws. This exclusive forum provision may limit the ability of a limitedpartner to commence litigation in a forum that the limited partner prefers, or may require a limited partner to incur additional costs in order to commence litigationin Delaware, each of which may discourage such lawsuits against us or our general partner’s directors or officers. Alternatively, if a court were to find thisexclusive forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings described above, we mayincur additional costs associated with resolving such matters in other jurisdictions, which could negatively affect our business, results of operations and financialcondition.The NYSE does not require a publicly traded partnership like us to comply with certain of its corporate governance requirements.Our common units are listed on the NYSE. Because we are a publicly traded partnership, the NYSE does not require us to have a majority of independentdirectors on the Board or to establish a compensation committee or a nominating and corporate governance committee. Accordingly, unitholders do not have thesame protections afforded to investors in certain corporations that are subject to all of the NYSE corporate governance requirements. Please read Part III, Item 10“Directors, Executive Officers and Corporate Governance”.29Table of ContentsTax Risks to Common UnitholdersOur tax treatment depends on our status as a partnership for federal income tax purposes. If the IRS were to treat us as a corporation for federal incometax purposes, then our cash available for distribution would be substantially reduced.The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for federal income taxpurposes. We have not requested a ruling from the IRS on this or any other tax matter affecting us.Despite the fact that we are a limited partnership under Delaware law, it is possible in certain circumstances for a partnership such as ours to be treated as acorporation for federal income tax purposes. Although we do not believe based upon our current operations that we are or will be so treated, a change in ourbusiness or a change in current law could cause us to be treated as a corporation for federal income tax purposes or otherwise subject us to taxation as an entity.If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate, andwould likely pay state and local income tax at varying rates. Distributions would generally be taxed again as corporate dividends (to the extent of our current andaccumulated earnings and profits), and no income, gains, losses, deductions or credits would flow through to you. Because a tax would be imposed upon us as acorporation, our cash available for distribution would be substantially reduced. Therefore, if we were treated as a corporation for federal income tax purposes, therewould be a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our commonunits.The Partnership Agreement provides that, if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporationor otherwise subjects us to entity level taxation for federal, state or local income tax purposes, the level of distributions on our common units may be adjusted toreflect the impact of that law or interpretation on us.If we were subjected to a material amount of additional entity level taxation by individual states, it would reduce our cash available for distribution.Changes in current state law may subject us to additional entity level taxation by individual states. Because of widespread state budget deficits and otherreasons, several states are evaluating ways to subject partnerships to entity level taxation through the imposition of state income, franchise and other forms oftaxation. For example, we are required to pay the Texas Margin Tax each year at a maximum effective rate of 0.75% of our “margin”, as defined in the law,apportioned to Texas in the prior year. Imposition of any similar taxes by any other state may substantially reduce the cash available for distribution and, therefore,negatively impact the value of an investment in our common units.The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrativechanges or differing interpretations, possibly applied on a retroactive basis.The present federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units, may be modified byadministrative, legislative or judicial changes or differing interpretations at any time. From time to time, members of the U.S. Congress have proposed andconsidered substantive changes to the existing federal income tax laws that would affect publicly traded partnerships, including elimination of partnership taxtreatment for certain publicly traded partnerships. For example, the “Clean Energy for America Act,” which is similar to legislation that was commonly proposedduring the Obama Administration, was introduced in the Senate on May 2, 2019. If enacted, this proposal would, among other things, repeal the qualifying incomeexception within Section 7704(d)(1)(E) of the Internal Revenue Code of 1986, as amended, upon which we rely for our treatment as a partnership for U.S. federalincome tax purposes. In addition, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly tradedpartnerships. There can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department’s interpretation of thequalifying income rules in a manner that could impact our ability to qualify as a partnership in the future.Any modification to the federal income tax laws and interpretations thereof may or may not be applied retroactively and could make it more difficult orimpossible for us to meet the exception for certain publicly traded partnerships to be treated as partnerships for federal income tax purposes. We are unable topredict whether any changes or other proposals will ultimately be enacted. Any future legislative changes could negatively impact the value of an investment in ourcommon units. You are urged to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and theirpotential effect on your investment in our common units.30Table of ContentsOur unitholders’ share of our income will be taxable to them for federal income tax purposes even if they do not receive any cash distributions from us.Our unitholders will be treated as partners to whom we will allocate taxable income. Unitholders are required to pay federal income taxes and, in some cases,state and local income taxes, on their share of our taxable income, whether or not they receive cash distributions from us. Unitholders may not receive cashdistributions from us equal to their share of our taxable income or even equal to the actual tax due from them with respect to that income.We may engage in transactions to de-lever the Partnership and manage our liquidity that may result in income and gain to our unitholders. For example, if wesell assets and use the proceeds to repay existing debt or fund capital expenditures, you may be allocated taxable income and gain resulting from the sale. Further,taking advantage of opportunities to reduce our existing debt, such as debt exchanges, debt repurchases, or modifications of our existing debt could result in“cancellation of indebtedness income” (also referred to as “COD income”) being allocated to our unitholders as taxable income. Unitholders may be allocatedCOD income, and income tax liabilities arising therefrom may exceed cash distributions. The ultimate effect of any such allocations will depend on theunitholder’s individual tax position with respect to its units. Unitholders are encouraged to consult their tax advisors with respect to the consequences of potentialCOD income or other transactions that may result in income and gain to unitholders.If the IRS contests the federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contestwill reduce our cash available for distribution.We have not requested a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes or any other matter affecting us.The IRS may adopt positions that differ from the positions we take, and the IRS’s positions may ultimately be sustained.It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all ofthe positions we take. Any contest with the IRS, and the outcome of any IRS contest, may have a materially adverse impact on the market for our common unitsand the price at which they trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders because the costs will reduce ourcash available for distribution.If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some states) may assess and collectany taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from us, in which case our cash available fordistribution to our unitholders might be substantially reduced.Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns,it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from us. Tothe extent possible under the new rules, the 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. Although theGeneral Partner may elect to have our unitholders and former unitholders take such audit adjustment into account and pay any resulting taxes (including applicablepenalties or interest) in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical,permissible or effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment,even if such unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments oftaxes, penalties and interest, our cash available for distribution to our unitholders might be reduced. These rules are not applicable for tax years beginning on orprior to December 31, 2017.Tax gain or loss on the disposition of our common units could be more or less than expected.If our unitholders sell common units, they will recognize a gain or loss for federal income tax purposes equal to the difference between the amount realizedand their tax basis in those common units. Because distributions in excess of their allocable share of our net taxable income decrease their tax basis in theircommon units, the amount, if any, of such prior excess distributions with respect to the common units a unitholder sells will, in effect, become taxable income tothe unitholder if it sells such common units at a price greater than its tax basis in those common units, even if the price received is less than its original cost. Inaddition, because the amount realized includes a unitholder’s share of our nonrecourse liabilities, a unitholder that sells common units may incur a tax liability inexcess of the amount of cash received from the sale.A substantial portion of the amount realized from a unitholder’s sale of our units, whether or not representing gain, may be taxed as ordinary income to suchunitholder due to potential recapture items, including depreciation recapture. Thus, a unitholder31Table of Contentsmay recognize both ordinary income and capital loss from the sale of units if the amount realized on a sale of such units is less than such unitholder’s adjustedbasis in the units. Net capital loss may only offset capital gains and, in the case of individuals, up to $3,000 of ordinary income per year. In the taxable period inwhich a unitholder sells its units, such unitholder may recognize ordinary income from our allocations of income and gain to such unitholder prior to the sale andfrom recapture items that generally cannot be offset by any capital loss recognized upon the sale of units.Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year.However, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, our deduction for “business interest” is limited to the sum of ourbusiness interest income and 30% of our “adjusted taxable income.” For the purposes of this limitation, our adjusted taxable income is computed without regard toany business interest expense or business interest income, and in the case of taxable years beginning before January 1, 2022, any deduction allowable fordepreciation, amortization, or depletion to the extent such depreciation, amortization, or depletion is not capitalized into cost of goods sold with respect toinventory. If our “business interest” is subject to limitation under these rules, our unitholders will be limited in their ability to deduct their share of any interestexpense that has been allocated to them. As a result, unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.Tax-exempt entities face unique tax issues from owning our common units that may result in adverse tax consequences to them.Investment in our common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs) raises issuesunique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and otherretirement plans, will be unrelated business taxable income and will be taxable to them. With respect to taxable years beginning after December 31, 2017, subjectto the proposed aggregation rules for certain similarly situated businesses or activities issued by the Treasury Department, a tax-exempt entity with more than oneunrelated trade or business (including by attribution from investment in a partnership such as ours) is required to compute the unrelated business taxable income ofsuch tax-exempt entity separately with respect to each such trade or business (including for purposes of determining any net operating loss deduction). As a result,for years beginning after December 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an investment in our partnership to offsetunrelated business taxable income from another unrelated trade or business and vice versa. Tax-exempt entities should consult a tax advisor before investing in ourcommon units.Non-U.S. unitholders will be subject to U.S. taxes and withholding with respect to their income and gain from owning our units.Non-U.S. unitholders are generally taxed and subject to income tax filing requirements by the United States on income effectively connected with a U.S. tradeor business (“effectively connected income”). Income allocated to our unitholders and any gain from the sale of our units will generally be considered to be“effectively connected” with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicableeffective tax rate and a non-U.S. unitholder who sells or otherwise disposes of a unit will also be subject to U.S. federal income tax on the gain realized from thesale or disposition of that unit.Moreover, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required to withhold 10% of the amount realizedby the transferor unless the transferor certifies that it is not a foreign person, and we are required to deduct and withhold from the transferee amounts that shouldhave been withheld by the transferees but were not withheld. Because the “amount realized” includes a partner’s share of the partnership’s liabilities, 10% of theamount realized could exceed the total cash purchase price for the units. However, pending the issuance of final regulations, the IRS has suspended the applicationof this withholding rule to transfers of publicly traded interests in publicly traded partnerships. If recently promulgated regulations are finalized as proposed, suchregulations would provide, with respect to transfers of publicly traded interests in publicly traded partnerships effected through a broker, that the obligation towithhold is imposed on the transferor’s broker and that a partner’s “amount realized” does not include a partner’s share of a publicly traded partnership’s liabilitiesfor purposes of determining the amount subject to withholding. However, it is not clear when such regulations will be finalized and if they will be finalized in theircurrent form.32Table of ContentsWe treat each purchaser of our common units as having the same tax benefits without regard to the actual common units purchased. The IRS maychallenge this treatment, which could adversely affect the value of our common units.Because we cannot match transferors and transferees of common units, we have adopted certain methods for allocating depreciation and amortizationdeductions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to the use of these methods could adversely affect theamount of tax benefits available to you. It also could affect the timing of these tax benefits or the amount of gain from your sale of common units and could have anegative impact on the value of our common units or result in audit adjustments to your tax returns.We generally prorate our items of income, gain, loss and deduction for federal income tax purposes between transferors and transferees of our units eachmonth based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS maychallenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.We generally prorate our items of income, gain, loss and deduction for federal income tax purposes between transferors and transferees of our units eachmonth based upon the ownership of our units on the first day of each month (the “Allocation Date”), instead of on the basis of the date a particular unit istransferred. Similarly, we generally allocate (i) certain deductions for depreciation of capital additions, (ii) gain or loss realized on a sale or other disposition of ourassets, and (iii) in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction based upon ownership on the AllocationDate. Treasury Regulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects of our proration method.If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among ourunitholders.A unitholder whose common units are the subject of a securities loan (e.g., a loan to a “short seller” to cover a short sale of common units) may beconsidered as having disposed of those common units. If so, he would no longer be treated for federal income tax purposes as a partner with respect to thosecommon units during the period of the loan and may recognize gain or loss from the disposition.Because there are no specific rules governing the federal income tax consequences of loaning a partnership interest, a unitholder whose common units are thesubject of a securities loan may be considered to have disposed of the loaned common units. In that case, the unitholder may no longer be treated for federalincome tax purposes as a partner with respect to those common units during the period of the loan to the short seller and the unitholder may recognize gain or lossfrom such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those common units may not bereportable by the unitholder and any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income. Unitholdersdesiring to assure their status as partners and avoid the risk of gain recognition from a securities loan are urged to consult a tax advisor to determine whether it isadvisable to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their common units.We have adopted certain valuation methodologies in determining a unitholder’s allocations of income, gain, loss and deduction. The IRS may challengethese methodologies or the resulting allocations, and such a challenge could adversely affect the value of our common units.In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our assets.Although we may from time to time consult with professional appraisers regarding valuation matters, we make many fair market value estimates using amethodology based on the market value of our common units as a means to measure the fair market value of our assets. The IRS may challenge these valuationmethods and the resulting allocations of income, gain, loss and deduction.A successful IRS challenge to these methods or allocations could adversely affect the timing or amount of taxable income or loss being allocated to ourunitholders. It also could affect the amount of gain recognized from our unitholders’ sale of common units, have a negative impact on the value of the commonunits, or result in audit adjustments to our unitholders’ tax returns without the benefit of additional deductions.As a result of investing in our common units, you will likely become subject to state and local taxes and income tax return filing requirements injurisdictions where we operate or own or acquire properties.In addition to federal income taxes, our unitholders will likely be subject to other taxes, including state and local taxes, unincorporated business taxes andestate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or control property now or in the future, even ifthey do not live in any of those jurisdictions. Our unitholders33Table of Contentswill likely be required to file state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions. Further, ourunitholders may be subject to penalties for failure to comply with state and local filing requirements.We currently conduct business and control assets in several states, many of which currently impose a personal income tax on individuals. Many of these statesalso impose an income tax on corporations and other entities. As we make acquisitions or expand our business, we may control assets or conduct business inadditional states or foreign jurisdictions that impose an income tax. It is your responsibility to file all foreign, federal, state and local tax returns and pay any taxesdue in these jurisdictions. Unitholders should consult with their own tax advisors regarding the filing of such tax returns, the payment of such taxes, and thedeductibility of any taxes paid.ITEM 1B.Unresolved Staff CommentsNone.ITEM 2.PropertiesWe do not currently own or lease any material facilities or properties for storage or maintenance of our compression units.

ETO owns 100% of the membership interests in the General Partner and, as ofFebruary 13, 2020, beneficially owns approximately 48% of our outstanding common units.As of February 13, 2020, we had outstanding 500,000 Preferred Units representing limited partner interests in the Partnership, all of which were held byPreferred Unitholders. The Preferred Units rank senior to the common units with respect to distributions and rights upon liquidation. The Preferred Unitholders areentitled to receive cumulative quarterly cash distributions equal to $24.375 per Preferred Unit.The Preferred Units are convertible, at the option of the Preferred Unitholders, into common units in accordance with the terms of the Partnership Agreementas follows: one third on or after April 2, 2021, two thirds on or after April 2, 2022, and the remainder on or after April 2, 2023. On or after April 2, 2023, we havethe option to redeem all or any portion of the Preferred Units then outstanding. On or after April 2, 2028, the Preferred Unitholders have the right to require us toredeem all or a portion of the Preferred Units then outstanding, the purchase price for which we may elect to pay up to 50% in common units, subject to certainadditional limits.Our common units, which represent limited partner interests in us, are listed on the New York Stock Exchange (“NYSE”) under the symbol “USAC.”HoldersAt the close of business on February 13, 2020, based on information received from the transfer agent of the common units, we had 71 holders of record of ourcommon units. The number of record holders does not include holders of common units held in “street name” or persons, partnerships, associations, corporationsor other entities identified in security position listings maintained by depositories. There is no established public trading market for the Preferred Units, all ofwhich are owned by the Preferred Unitholders. Please read Part II, Item 8 “Financial Statements and Supplementary Data – Note 11 – Preferred Units andWarrants and – Note 12 – Partners’ Capital”.Selected Information from the Partnership AgreementSet forth below is a summary of the significant provisions of the Partnership Agreement that relate to available cash.Available CashThe Partnership Agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash to unitholders of record on theapplicable record date, first to the holders of the Preferred Units and then to the common unitholders. The Partnership Agreement generally defines available cash,for each quarter, as cash on hand at the end of a quarter plus cash on hand resulting from working capital borrowings made after the end of the quarter less theamount of reserves established by the General Partner to provide for the proper conduct of our business, comply with applicable law, the Credit Agreement or otheragreements; and provide funds for distributions to our unitholders for any one or more of the next four quarters. Working capital borrowings are borrowings madeunder a credit facility, commercial paper facility or other similar financing arrangement, and in all cases are used solely for working capital purposes or to paydistributions to partners and with the intent of the borrower to repay such borrowings within twelve months from sources other than working capital borrowings.Issuer Purchases of Equity SecuritiesNone.Sales of Unregistered Securities; Use of Proceeds from Sale of SecuritiesNone.35Table of ContentsEquity Compensation PlanFor disclosures regarding securities authorized for issuance under equity compensation plans, see Part III, Item 12 “Security Ownership of Certain BeneficialOwners and Management and Related Unitholder Matters”.ITEM 6.Selected Financial DataSELECTED HISTORICAL FINANCIAL DATAIn the table below we have presented certain selected financial data for USA Compression Partners, LP and the USA Compression Predecessor for each of theyears in the five-year period ended December 31, 2019, which has been derived from our audited consolidated financial statements for the years endedDecember 31, 2019, 2018, 2017, 2016 and 2015.

We define gross operating margin as revenue less cost of operations, exclusive of depreciation and amortization expense.We believe that gross operating margin is useful as a supplemental measure of our operating profitability. Gross operating margin is impacted primarily by thepricing trends for service operations and cost of operations, including labor rates for service technicians, volume and per unit costs for lubricant oils, quantity andpricing of routine preventative maintenance on compression units and property tax rates on compression units. Gross operating margin should not be considered analternative to, or more meaningful than, operating income (loss) or any other measure of financial performance presented in accordance with GAAP. Moreover,gross operating margin as presented may not be comparable to similarly titled measures of other companies. Because we capitalize assets, depreciation andamortization of equipment is a necessary element of our costs. To compensate for the limitations of gross operating margin as a measure of our performance, webelieve that it is important to consider operating income (loss) determined under GAAP, as well as gross operating margin, to evaluate our operating profitability.Adjusted EBITDAWe define EBITDA as net income (loss) before net interest expense, depreciation and amortization expense, and income tax expense (benefit). We defineAdjusted EBITDA as EBITDA plus impairment of compression equipment, impairment of goodwill, interest income on capital lease, unit-based compensationexpense, severance charges, certain transaction fees, loss (gain) on disposition of assets and other. We view Adjusted EBITDA as one of management’s primarytools for evaluating our results of operations, and we track this item on a monthly basis both as an absolute amount and as a percentage of revenue compared to theprior month, year-to-date, prior year and budget. Adjusted EBITDA is used as a supplemental financial measure by our management and external users of ourfinancial statements, such as investors and commercial banks, to assess:•the financial performance of our assets without regard to the impact of financing methods, capital structure or historical cost basis of ourassets;•the viability of capital expenditure projects and the overall rates of return on alternative investmentopportunities;•the ability of our assets to generate cash sufficient to make debt payments and to pay distributions;and•our operating performance as compared to those of other companies in our industry without regard to the impact of financing methods and capitalstructure.We believe that Adjusted EBITDA provides useful information to investors because, when viewed with our GAAP results and the accompanyingreconciliations, it may provide a more complete understanding of our performance than GAAP results alone. We also believe that external users of our financialstatements benefit from having access to the same financial measures that management uses in evaluating the results of our business.Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income (loss), operating income (loss), cash flows from operatingactivities or any other measure of financial performance or liquidity presented in accordance with GAAP as measures of operating performance and liquidity.Moreover, our Adjusted EBITDA as presented may not be comparable to similarly titled measures of other companies.Because we use capital assets, depreciation, impairment of compression equipment, loss (gain) on disposition of assets and the interest cost of acquiringcompression equipment are also necessary elements of our costs. Unit-based compensation expense related to equity awards to employees is also a necessarycomponent of our business. Therefore, measures that exclude these elements have material limitations. To compensate for these limitations, we believe that it isimportant to consider both net income (loss) and net cash provided by operating activities determined under GAAP, as well as Adjusted EBITDA, to evaluate ourfinancial performance and our liquidity. Our Adjusted EBITDA excludes some, but not all, items that affect net income (loss) and net cash provided by operatingactivities, and these measures may vary among companies.

Using DCF, management can quickly compute the coverage ratio of estimated cash flows to planned cashdistributions.39Table of ContentsDCF should not be considered an alternative to, or more meaningful than, net income (loss), operating income (loss), cash flows from operating activities orany other measure of financial performance presented in accordance with GAAP as measures of operating performance and liquidity. Moreover, our DCF aspresented may not be comparable to similarly titled measures of other companies.Because we use capital assets, depreciation, impairment of compression equipment, loss (gain) on disposition of assets, the interest cost of acquiringcompression equipment and maintenance capital expenditures are necessary elements of our costs. Unit-based compensation expense related to equity awards toemployees is also a necessary component of our business. Therefore, measures that exclude these elements have material limitations. To compensate for theselimitations, we believe that it is important to consider both net income (loss) and net cash provided by operating activities determined under GAAP, as well asDCF, to evaluate our financial performance and our liquidity. Our DCF excludes some, but not all, items that affect net income (loss) and net cash provided byoperating activities, and these measures may vary among companies. Management compensates for the limitations of DCF as an analytical tool by reviewing thecomparable GAAP measures, understanding the differences between the measures and incorporating this knowledge into their decision making processes.40Table of ContentsThe following table reconciles DCF to net income (loss) and net cash provided by operating activities, its most directly comparable GAAP financial measures,for each of the periods presented (in thousands): Year Ended December 31, 2019 2018 2017 2016 2015Net income (loss)$39,132 $(10,551) $(264,734) $(26,944) $4,191Non-cash interest expense7,607 5,080 — — —Depreciation and amortization231,447 213,692 166,558 155,134 148,930Non-cash income tax expense (benefit)1,376 (2,663) 1,801 (155) (1,461)Unit-based compensation expense (1)10,814 11,740 4,048 3,539 3,972Transaction expenses (2)578 4,181 — — —Severance charges831 3,171 — — —Loss (gain) on disposition of assets940 12,964 (367) 120 (603)Impairment of compression equipment (3)5,894 8,666 — — —Impairment of goodwill (4)— — 223,000 — —Distributions on Preferred Units(48,750) (36,430) — — —Proceeds from insurance recovery1,591 409 — — —Maintenance capital expenditures (5)(29,592) (32,502) (20,980) (8,252) (7,837)DCF$221,868 $177,757 $109,326 $123,442 $147,192Maintenance capital expenditures29,592 32,502 20,980 8,252 7,837Transaction expenses(578) (4,181) — — —Severance charges(831) (3,171) — — —Distributions on Preferred Units48,750 36,430 — — —Other(541) 224 (1,777) (593) 4,841Changes in operating assets and liabilities2,320 (13,221) 7,427 (1,038) 4,454Net cash provided by operating activities$300,580 $226,340 $135,956 $130,063 $164,324________________________________(1)For the years ended December 31, 2019 and 2018, unit-based compensation expense included $2.5 million and $1.3 million of cash payments related to quarterly paymentsof distribution equivalent rights on outstanding phantom unit awards, respectively, and $0.6 million and $3.7 million related to the cash portion of any settlement ofphantom unit awards upon vesting, respectively.

Maintenance capital expenditures are capital expenditures made to maintain the operatingcapacity of our assets and extend their useful lives, replace partially or fully depreciated assets, or other capital expenditures that are incurred in maintaining our existingbusiness and related cash flow.Coverage RatiosDCF Coverage Ratio is defined as DCF divided by distributions declared to common unitholders in respect of such period. Cash Coverage Ratio is defined asDCF divided by cash distributions expected to be paid to common unitholders in respect of such period, after taking into account the non-cash impact of the DRIP.We believe DCF Coverage Ratio and Cash Coverage Ratio are important measures of operating performance because they allow management, investors and othersto gauge our ability to pay cash distributions to common unitholders using the cash flows that we generate.

ITEM 7.Management’s Discussion and Analysis of Financial Condition and Results ofOperationsFollowing the transactions described in further detail below, CDM Resource Management LLC (“CDM Resource”) and CDM Environmental & TechnicalServices LLC (“CDM E&T”), which together represent the CDM Compression Business (the “USA Compression Predecessor”), has been determined to be thehistorical predecessor of USA Compression Partners, LP (the “Partnership”) for financial reporting purposes. The USA Compression Predecessor is consideredthe predecessor of the Partnership because Energy Transfer Equity LP (“ETE”), through its wholly owned subsidiary Energy Transfer Partners, L.L.C., (“ETPLLC”) controlled the USA Compression Predecessor prior to the transactions described below and obtained control of the Partnership through its acquisition ofUSA Compression GP, LLC, the general partner of the Partnership (the “General Partner”).The closing of the Transactions occurred on April 2, 2018 (the “Transactions Date”) and has been reflected in the consolidated financial statements of thePartnership.In October 2018, ETE and Energy Transfer Partners, L.P. (“ETP”) completed the merger of ETP with a wholly owned subsidiary of ETE in a unit-for-unitexchange (the “ETE Merger”). Following the closing of the ETE Merger, ETE changed its name to “Energy Transfer LP” (“ET LP”) and ETP changed its nameto “Energy Transfer Operating, L.P.” (“ETO”). Upon the closing of the ETE Merger, ETE contributed to ETO 100% of the limited liability company interests inthe General Partner. References herein to “ETO” refer to ETP for periods prior to the ETE Merger and ETO following the ETE Merger, and references to “ETLP” refer to ETE for periods prior to the ETE Merger and ET LP following the ETE Merger.The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financialstatements, the notes thereto, and the other financial information appearing elsewhere in this report. The following discussion includes forward-looking statementsthat involve certain risks and uncertainties. See Part I “Disclosure Regarding Forward-Looking Statements” and Part I, Item 1A “Risk Factors”. All referencesin this section to the USA Compression Predecessor, as well as the terms “our,” “we,” “us” and “its” refer to the USA Compression Predecessor when used in ahistorical context or in reference to the periods prior to the Transactions Date, unless the context otherwise requires or where otherwise indicated.

Demand for our services is driven by the domestic productionof natural gas and crude oil; as such, we have focused our activities in areas with attractive natural gas and crude oil production growth, which are generally foundin these shale and unconventional resource plays. According to studies promulgated by the U.S. Energy Information Administration (“EIA”), the production andtransportation volumes of these shale plays, in aggregate, are expected to increase over the long term due to the comparatively attractive economic returns versusreturns achieved in many conventional basins. Furthermore, the changes in production volumes and pressures of shale plays over time require a wider range ofcompression services than in conventional basins. We believe we are well-positioned to meet these changing operating conditions due to the flexibility of ourcompression units. While our business focuses largely on compression services serving infrastructure applications, including centralized natural gas gatheringsystems and processing facilities, which utilize large horsepower compression units, typically in shale plays, we also provide compression services in moremature conventional basins, including gas lift applications on crude oil wells targeted by horizontal drilling techniques. Gas lift, a process by which natural gas isinjected into the production tubing of an existing producing well, in order to reduce the hydrostatic pressure and allow the oil to flow at a higher rate, and otherartificial lift technologies are critical to the enhancement of oil production from horizontal wells operating in tight shale plays.Recent Developments2027 Senior Notes Issuance and ExchangeOn March 7, 2019, the Partnership and its wholly owned finance subsidiary, USA Compression Finance Corp. (“Finance Corp”) co-issued $750.0million aggregate principal amount of senior notes due on September 1, 2027 (the “Senior Notes 2027”). The Senior Notes 2027 accrue interest from March 7,2019 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, with the first suchpayment having occurred on September 1, 2019.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 anequivalent amount of senior notes (“Exchange Notes 2027”) registered under the Securities Act of 1933, as amended (“Securities Act”). The Exchange Notes2027 are substantially identical to the Senior Notes 2027, except that the Exchange Notes 2027 have been registered with the U.S. Securities and ExchangeCommission (“SEC”) and do not contain the transfer restrictions, restrictive legends, registration rights or additional interest provisions of the Senior Notes 2027.2018 CDM Acquisition and Related TransactionsCDM Acquisition and Issuance of Class B UnitsOn the Transactions Date, we consummated the transactions contemplated by the Contribution Agreement dated January 15, 2018, pursuant to which, amongother things, we acquired all of the issued and outstanding membership interests of the USA Compression Predecessor from ETO (the “CDM Acquisition”) inexchange for aggregate consideration of approximately $1.7 billion, consisting of (i) 19,191,351 common units representing limited partner interests in us (the“common units”), (ii) 6,397,965 Class B units representing limited partner interests in us (“Class B Units”) and (iii) $1.2 billion in cash (including customaryclosing adjustments). On July 30, 2019, 6,397,965 Class B Units automatically converted into common units on a one-for-one basis, resulting in the issuance of6,397,965 common units to ETO. Following the conversion, there are no longer Class B Units outstanding.43Table of ContentsGeneral Partner Purchase AgreementOn the Transactions Date, and in connection with the closing of the CDM Acquisition, we consummated the transactions contemplated by the PurchaseAgreement dated January 15, 2018, by and among ET LP, ETP LLC, USA Compression Holdings, LLC (“USA Compression Holdings”) and, solely for certainpurposes therein, R/C IV USACP Holdings, L.P. and ETO, pursuant to which, among other things, ET LP acquired from USA Compression Holdings (i) all of theoutstanding limited liability company interests in the General Partner and (ii) 12,466,912 common units for cash consideration paid by ET LP to USACompression Holdings equal to $250.0 million (the “GP Purchase”). Upon the closing of the ETE Merger, ET LP contributed all of the interests in the GeneralPartner and the 12,466,912 common units to ETO.Equity Restructuring AgreementOn the Transactions Date, and in connection with the closing of the CDM Acquisition, we consummated the transactions contemplated by the EquityRestructuring Agreement dated January 15, 2018 (the “Equity Restructuring Agreement”), pursuant to which, among other things, the Partnership, the GeneralPartner and ET LP agreed to cancel the Partnership’s Incentive Distribution Rights (“IDRs”) and convert the General Partner’s interest into a non-economic generalpartner interest, in exchange for the Partnership’s issuance of 8,000,000 common units to the General Partner (the “Equity Restructuring”). In addition, at any timeafter one year following the Transactions Date, ET LP has the right to contribute (or cause any of its subsidiaries to contribute) to us all of the outstanding equityinterests in any of its subsidiaries that owns the general partner interest in us in exchange for $10.0 million (the “GP Contribution”); provided that the GPContribution will occur automatically if at any time following the Transactions Date (i) ET LP or one of its subsidiaries (including ETO) owns, directly orindirectly, the general partner interest in us and (ii) ET LP and its subsidiaries (including ETO) collectively own less than 12,500,000 of our common units.The CDM Acquisition, GP Purchase and Equity Restructuring are collectively referred to as the “Transactions.”Series A Preferred Unit and Warrant Private PlacementOn the Transactions Date, we completed a private placement of $500 million in the aggregate of (i) newly authorized and established Series A Preferred Unitsrepresenting limited partner interests in us (the “Preferred Units”) and (ii) warrants to purchase common units (the “Warrants”) pursuant to a Series A PreferredUnit and Warrant Purchase Agreement dated January 15, 2018, between the Partnership and certain investment funds managed or advised by EIG Global EnergyPartners and FS Energy and Power Fund (collectively, the “Preferred Unitholders”). We issued 500,000 Preferred Units with a face value of $1,000 per PreferredUnit and issued two tranches of Warrants to the Preferred Unitholders, which included Warrants to purchase 5,000,000 common units with a strike price of $17.03per unit and 10,000,000 common units with a strike price of $19.59 per unit. The Warrants may be exercised by the holders thereof at any time beginning April 2,2019 and before April 2, 2028. 2026 Senior Notes Issuance and ExchangeOn March 23, 2018, the Partnership and Finance Corp co-issued $725.0 million aggregate principal amount of senior notes due on April 1, 2026 (the “SeniorNotes 2026”).

Ourbusiness is driven in part by the increasing volumes of natural gas being produced in this country and the areas and conditions in which it is produced. Compressionis generally required throughout the life of a producing basin; areas of moderating or declining natural gas production require compression to achieve minimumpressure to enter gathering and transmission pipelines. Without compression, natural gas will generally not move through a pipeline and can thus become strandedin a given area.A significant amount of our assets are utilized in natural gas infrastructure applications, primarily in centralized natural gas gathering systems and processingfacilities. Rather than being more closely tied to the wellhead impact of commodity price variability, these applications generally tend to be characterized by along-term investment horizon on the part of our customers; as such, we have generally experienced stability in rates and higher sustained utilization rates relative toother businesses more tied to drilling activity and wellhead economics. In addition to assets utilized in infrastructure applications, a small portion of our fleethorsepower is used for gas lift applications in connection with crude oil production using horizontal drilling techniques.Increasing levels of domestic natural gas production as a general rule require more installed compression in order to move the gas through the pipeline systemand to the ultimate end user, whether that user be commercial, industrial or residential in nature. The EIA’s January 2020 Short-Term Energy Outlook (“EIAOutlook”) expects dry natural gas production to increase to 94.7 billion cubic feet per day (“Bcf/d”) in 2020 (an increase of 3% over the record high production of92.0 Bcf/d in 2019) and then decline to 94.1 Bcf/d in 2021. The EIA’s expected growth in natural gas production for 2020 is largely in response to improveddrilling efficiency and cost reductions, higher associated gas production from oil-directed rigs, and increased takeaway pipeline capacity from the Appalachian andPermian production regions. Forecast natural gas production growth is also supported by planned expansions in liquefied natural gas (“LNG”) capacity andincreased pipeline exports to Mexico. The decline in natural gas production in 2021 is in response to a forecast of low natural gas spot prices in 2020 that reducesdrilling activity in the Appalachian Basin.Henry Hub natural gas spot prices averaged $2.57 per million British thermal units (“MMBtu”) in 2019, down from $3.16/MMBtu in 2018. The EIA Outlookexpects Henry Hub prices to decrease to an average of to $2.33/MMBtu in 2020 and then increase to an average of $2.54/MMBtu in 2021.Recently, overall domestic natural gas production has increased significantly to meet the growing demand domestically as well as abroad, through, amongother things, LNG exports. Over the last ten years, the EIA Outlook reports that dry natural gas production has increased by 63%, or approximately 5% annually.This increase has caused meaningful demand for our services as operators have built out the necessary infrastructure to move, process and consume these increasedvolumes of natural gas.While the EIA expects the overall trajectory of natural gas production to moderate, we believe demand for compression services will continue to increasebecause, as high-decline shale wells begin to age and production is tempered, new sources of natural gas will be required in order to meet demand. Although wecannot predict any possible changes in demand with reasonable certainty, we expect demand for our compression services to remain strong throughout 2020.Particularly in the Permian and Delaware Basins, natural gas tends to be produced alongside crude oil, and is thus known as “associated” gas. Due to manyfactors, the Permian and Delaware Basins have experienced significant activity levels in recent years, and along with the production of crude oil, the EIA hasreported a 157% increase in associated natural gas produced in those areas since December 2015 and a 24% increase in December 2019 as compared to December2018. Because customers must handle the associated natural gas, compression has been a critical part of the equation for our customers to be able to produce thedesired crude oil and move it to market. Given the relatively attractive economics of producing crude oil in the Permian and Delaware Basins, these areas areexpected to continue to be important sources of crude oil, along with the associated natural gas,45Table of Contentsin the coming years. As crude oil production grows in these areas, there will be demand for additional compression to handle the associated natural gas.The EIA Outlook forecasts total U.S. crude oil production to average 13.3 million barrels per day (“bbl/d”) in 2020, up 9% from 2019 average production of12.2 million bbl/d, which was the highest annual average on record. Average production in 2021 is expected to continue to increase to 13.7 million bbl/d. Almostall of the production growth within the U.S. is expected to be attributable to onshore production within the lower 48 states, and particularly from the Permian andDelaware Basins in Texas and New Mexico, which account for 0.8 million bbl/d and 0.4 million bbl/d of the increases in 2020 and 2021, respectively. Favorablegeology and technological and operational improvements have allowed the Permian and Delaware Basins to become one of the most prolific regions for oilproduction. The EIA Outlook forecasts a slowing rate of increases in year-over-year crude oil production, primarily as a result of a decline in the deployment ofdrilling rigs over the past year, a trend which the EIA expects will continue through 2020 and into 2021. Despite the decline in the number of drilling rigs, the EIAforecasts production will continue to grow as rig efficiency and well-level productivity rise. As crude oil production grows, we expect natural gas production togrow as well.For 2020, the EIA’s West Texas Intermediate (“WTI”) crude oil price forecast rises by $2 per barrel (“/bbl”) from 2019 levels to average $59/bbl for the year.For 2021, the EIA expects WTI prices will rise further to an average of $62/bbl. The EIA expects oil prices above $60/bbl to contribute to rising crude oilproduction, as producers will be able to fund drilling programs through cash flow and other funding sources, despite a somewhat more restrictive capital market.Daily and monthly average crude oil prices could vary significantly from annual average forecasts due to global economic developments and geopolitical events inthe coming months that could have the potential to push oil prices higher or lower than forecast. Uncertainty remains regarding the duration of, and members’adherence to, the current Organization of the Petroleum Exporting Countries (“OPEC”) production cuts, which could influence prices in either direction.We believe the recent stability of crude oil prices during 2019 and 2018 has allowed for the continued build-out of related large-scale natural gas infrastructureprojects, particularly in the Permian and Delaware Basins. Our total fleet horsepower has increased by approximately 86,000 horsepower as of December 31, 2019compared to December 31, 2018, while maintaining horsepower utilization at approximately 94%.We intend to prudently deploy capital for new compressor units in 2020. We have already entered into commitments to purchase all of our large horsepowercompressor units for the first half of 2020, as the lead time to build these units is approximately six months. Most of our 2020 purchases of large horsepowercompressor units are already committed to customers or under contract with customers.Factors Affecting the Comparability of our Operating ResultsAs described above, the USA Compression Predecessor has been deemed to be the accounting acquirer of the Partnership in accordance with applicablebusiness combination accounting guidance, and, as a result, the historical financial statements reflect the results of operations of the USA Compression Predecessorfor periods prior to the Transactions Date. Therefore, the Partnership’s future results of operations may not be comparable to the USA Compression Predecessor’shistorical results of operations for the reasons described below.The revenues generated by the Partnership consist of the revenues from compression services as well as related ancillary revenues, including those generatedby the USA Compression Predecessor, subsequent to the Transactions Date. The historical revenues included within the Partnership’s financial statements relatingto periods prior to the Transactions Date are only comprised of those of the USA Compression Predecessor. Additionally, selling, general and administrative expenses will not be comparable to the selling, general and administrative expenses previously allocated tothe USA Compression Predecessor by ETO. The Partnership’s selling, general and administrative expenses will also not be comparable to the historical USACompression Predecessor’s selling, general and administrative expenses because the Partnership’s selling, general and administrative expenses will include theexpenses associated with being a publicly traded master limited partnership, whereas the USA Compression Predecessor was operated as a component of a largercompany.The Partnership incurs interest on its long-term debt and makes distributions to its unitholders. The USA Compression Predecessor held no long-term debt andhad no outstanding publicly traded equity securities. As a result, the Partnership’s long-term debt and related charges will not be comparable to the USACompression Predecessor’s historical long-term debt and related charges.46Table of ContentsDuring the year ended December 31, 2018, we recorded $4.2 million in transaction expenses, $3.2 million in severance expenses and $6.8 million in unit-based compensation expense, all of which related to the CDM Acquisition.Operating HighlightsThe following table summarizes certain horsepower and horsepower utilization percentages for the periods presented and excludes certain gas treating assetsfor which horsepower is not a relevant metric.

Horsepower utilization based on revenue generating horsepower and fleet horsepower was 89.9% and 90.7% at December 31,2019 and 2018, respectively.(8)Calculated as the average utilization for the months in the period based on utilization at the end of each month in the period. Average horsepower utilization based onrevenue generating horsepower and fleet horsepower was 89.8% and 87.5% for the years ended December 31, 2019 and 2018, respectively.The 2.4% increase in fleet horsepower as of December 31, 2019 compared to December 31, 2018 was attributable to compression units added to our fleet tomeet incremental demand by new and current customers for our compression services. The 1.5% increase in revenue generating horsepower as of December 31,2019 compared to December 31, 2018 was primarily due to organic growth in our large horsepower fleet, while the 1.5% decrease in revenue generatingcompression units was primarily due to returns of small horsepower compression units from our customers, partially offset by the organic growth of largehorsepower compression units and a 4.8% increase in average horsepower per revenue generating compression unit during the year ended December 31, 2019.The 3.5% increase in average revenue per revenue generating horsepower per month for the year ended December 31, 2019 compared to the year endedDecember 31, 2018 was primarily due to contracts on new compression units as well as selective price increases on the existing fleet.47Table of ContentsThe 3.0% increase in average horsepower utilization and 2.6% increase in average horsepower utilization based on revenue generating horsepower and fleethorsepower during the year ended December 31, 2019 compared to the year ended December 31, 2018 were primarily attributable to increased demand for ourservices driven by increased U.S. production of crude oil and natural gas.Financial Results of OperationsYear ended December 31, 2019 compared to the year ended December 31, 2018The following table summarizes our results of operations for the periods presented (dollars in thousands): Year Ended December 31, Percent 2019 2018 ChangeRevenues: Contract operations$664,162 $546,896 21.4 %Parts and service14,236 20,402 (30.2)%Related party19,967 17,054 17.1 %Total revenues698,365 584,352 19.5 %Costs and expenses: Cost of operations, exclusive of depreciation and amortization227,303 214,724 5.9 %Gross operating margin471,062 369,628 27.4 %Other operating and administrative costs and expenses: Selling, general and administrative64,397 68,995 (6.7)%Depreciation and amortization231,447 213,692 8.3 %Loss on disposition of assets940 12,964 (92.7)%Impairment of compression equipment5,894 8,666 (32.0)%Total other operating and administrative costs and expenses302,678 304,317 (0.5)%Operating income168,384 65,311 157.8 %Other income (expense): Interest expense, net(127,146) (78,377) 62.2 %Other80 41 95.1 %Total other expense(127,066) (78,336) 62.2 %Net income (loss) before income tax expense (benefit)41,318 (13,025) 417.2 %Income tax expense (benefit)2,186 (2,474) 188.4 %Net income (loss)$39,132 $(10,551) 470.9 %Contract operations revenue. The $117.3 million increase in contract operations revenue for the year ended December 31, 2019 compared to the year endedDecember 31, 2018 was primarily attributable to the first three months of 2018 including only the results of the USA Compression Predecessor prior to theTransactions Date. Average revenue generating horsepower increased 18.8% for the year ended December 31, 2019 compared to the year ended December 31,2018 primarily due to the inclusion of the Partnership’s historical assets subsequent to the Transactions Date. Additionally, we experienced a year-to-year increasein demand for our compression services driven by increased U.S. production of crude oil and natural gas as average revenue per revenue generating horsepower permonth increased 3.5% to $16.65 for the year ended December 31, 2019 compared to $16.09 for the year ended December 31, 2018.Parts and service revenue. The $6.2 million decrease in parts and service revenue for the year ended December 31, 2019 compared to the year endedDecember 31, 2018 was primarily attributable to a decrease in maintenance work performed on units at our customers’ locations that are outside the scope of ourcore maintenance activities and offered as a courtesy to our customers, and freight and crane charges that are directly reimbursable by customers. Demand for retailparts and services fluctuates from period to period based on the varying needs of our customers.48Table of ContentsRelated party revenue. Related party revenue was earned through related party transactions in the ordinary course of business with various affiliated entities ofETO. The $2.9 million increase in related party revenue for the year ended December 31, 2019 compared to the year ended December 31, 2018 was primarilyattributable to additional compression and related ancillary services demand from such affiliates.Cost of operations, exclusive of depreciation and amortization. The $12.6 million increase in cost of operations for the year ended December 31, 2019compared to the year ended December 31, 2018 was driven by (1) a $21.1 million increase in direct expenses, such as parts and fluids expenses, and (2) a $5.3million increase in direct labor expenses, for which both increases were primarily attributable to the first three months of 2018 including only the results of theUSA Compression Predecessor prior to the Transactions Date. These increases were partially offset by (1) a $5.0 million decrease in ad valorem tax expense, dueprimarily to prior year refunds received during the year ended December 31, 2019, (2) a $3.9 million decrease in retail parts and service expenses, which have acorresponding decrease in parts and service revenue, (3) a $3.9 million decrease in outside maintenance services and (4) a $1.1 million decrease in other indirectexpenses.Gross operating margin. The $101.4 million increase in gross operating margin for the year ended December 31, 2019 compared to the year endedDecember 31, 2018 was primarily due to an increase in revenues, partially offset by an increase in cost of operations, exclusive of depreciation and amortization.These increases were primarily due to the addition of the Partnership’s historical assets after the Transactions Date and higher demand for our services driven byincreased U.S. production of crude oil and natural gas.Selling, general and administrative expense. The $4.6 million decrease in selling, general and administrative expense for the year ended December 31, 2019compared to the year ended December 31, 2018 was primarily attributable to (1) a $5.9 million decrease in transaction expenses and severance expenses, (2) a $3.2million decrease in other miscellaneous expenses, partially offset by (1) a $2.4 million increase in payroll and benefits expenses and (2) a $1.9 million increase inprofessional fees expenses.Transaction expenses and severance expenses were lower during the year ended December 31, 2019 primarily due to the Transactions completed during theyear ended December 31, 2018. Other miscellaneous expenses decreased primarily due to the expense allocation to the USA Compression Predecessor ending afterthe Transactions Date. Payroll and benefits expenses and professional fees increased due to the addition of the Partnership’s historical assets after the TransactionsDate.Depreciation and amortization expense. The $17.8 million increase in depreciation and amortization expense for the year ended December 31, 2019compared to the year ended December 31, 2018 was primarily the result of the addition of the Partnership’s historical assets on the Transactions Date and assetsrecently placed in service.Loss on disposition of assets. The $12.0 million decrease in net losses on disposition of assets during the year ended December 31, 2019 compared to the yearended December 31, 2018 was primarily attributable to disposals of various property and equipment by the USA Compression Predecessor prior to theTransactions Date during the year ended December 31, 2018.Impairment of compression equipment. The $5.9 million and $8.7 million impairments of compression equipment during the years ended December 31, 2019and 2018, respectively, were primarily the result of our evaluations of the future deployment of our idle fleet under then-current market conditions. Our evaluationsdetermined that due to certain performance characteristics of the impaired equipment, such as excessive maintenance costs and the inability of the equipment tomeet then-current emissions standards without excessive retrofitting costs, this equipment was unlikely to be accepted by customers under then-current marketconditions. As a result of our evaluations during the years ended December 31, 2019 and 2018, we determined to retire and re-utilize the key components of 33 and 103compression units, respectively, with a total of approximately 11,000 and 33,000 horsepower, respectively, that had been previously used to provide compressionservices in our business. Interest expense, net. The $48.8 million increase in interest expense, net for the year ended December 31, 2019 compared to the year ended December 31,2018 was primarily attributable to (1) higher overall debt balances as the USA Compression Predecessor had no borrowings prior to the Transactions Date, (2)interest expense incurred on $750.0 million of 6.875% senior notes issued in March 2019, which were used to reduce borrowings under the Credit Agreement, and(3) higher interest rates on borrowings under the Credit Agreement. These increases were partially offset by the decrease in borrowings under the CreditAgreement.The weighted average interest rate applicable to borrowings under the Credit Agreement was 4.84% for the year ended December 31, 2019 compared to 4.69%for the period from the Transactions Date to December 31, 2018. Average outstanding49Table of Contentsborrowings under the Credit Agreement were $493.3 million for the year ended December 31, 2019 compared to $984.7 million for the period from theTransactions Date to December 31, 2018.Income tax expense (benefit). During the years ended December 31, 2019 and 2018, we recognized income tax expense of $2.2 million and an income taxbenefit of $2.5 million, respectively, primarily related to current and deferred taxes associated with Texas Margin Tax.Other Financial DataThe following table summarizes other financial data for the periods presented (dollars in thousands): Year Ended December 31, PercentOther Financial Data: (1) 2019 2018 ChangeGross operating margin $471,062 $369,628 27.4 %Gross operating margin percentage (2) 67.5% 63.3% 6.6 %Adjusted EBITDA $419,640 $320,475 30.9 %Adjusted EBITDA percentage (2) 60.1% 54.8% 9.7 %DCF $221,868 $177,757 24.8 %DCF Coverage Ratio (3) 1.13x 1.25x (9.6)%Cash Coverage Ratio (3) 1.14x 1.26x (9.5)%________________________________(1)Gross operating margin, Adjusted EBITDA, DCF, DCF Coverage Ratio and Cash Coverage Ratio are all non-GAAP financial measures. Definitions of each measure, aswell as reconciliations of each measure to its most directly comparable financial measure(s) calculated and presented in accordance with GAAP, can be found under thecaption “Non-GAAP Financial Measures” in Part II, Item 6 “Selected Financial Data”.(2)Gross operating margin percentage and Adjusted EBITDA percentage are calculated as a percentage of revenue.(3)Distributions for the year ended December 31, 2018 reflect only three quarters of distributions as the USA Compression Predecessor did not pay distributions prior to theTransactions Date. DCF, however, reflects a full year of DCF. On a pro forma basis, both the DCF Coverage Ratio and Cash Coverage Ratio for the year endedDecember 31, 2018 were 1.10x when using comparable three quarters of DCF and three quarters of distributions.Adjusted EBITDA. The $99.2 million, or 30.9%, increase in Adjusted EBITDA for the year ended December 31, 2019 compared to the year endedDecember 31, 2018 was driven by the addition of the Partnership’s historical assets after the Transactions Date, which was the primary cause of a $101.4 millionincrease in gross operating margin. This increase was partially offset by a $2.2 million increase in selling, general and administrative expenses, excludingtransaction expenses, unit-based compensation expense and other non-recurring charges.DCF. The $44.1 million, or 24.8%, increase in DCF during the year ended December 31, 2019 compared to the year ended December 31, 2018 was driven by(1) the addition of the Partnership’s historical assets after the Transactions Date, which was the primary cause of a $101.4 million increase in gross operatingmargin, and (2) a $2.9 million decrease in maintenance capital expenditures. These increases were partially offset by (1) a $46.2 million increase in cash interestexpense, net, (2) a $12.3 million increase in distributions on the Preferred Units and (3) a $2.2 million increase in selling, general and administrative expenses,excluding transaction expenses, unit-based compensation expense and other non-recurring charges.Coverage Ratios. The decreases in DCF Coverage Ratio and Cash Coverage Ratio for the year ended December 31, 2019 compared to the year endedDecember 31, 2018 were attributable to the fact that distributions for year ended December 31, 2018 reflect only three quarters of distributions, as the USACompression Predecessor did not pay distributions prior to the Transactions Date, as well as additional distributions in 2019 due to the conversion of 6,397,965Class B Units, which did not participate in distributions, to common units on a one-for-one basis on July 30, 2019.50Table of ContentsLiquidity and Capital ResourcesOverviewWe operate in a capital-intensive industry, and our primary liquidity needs are to finance the purchase of additional compression units and make other capitalexpenditures, service our debt, fund working capital, and pay distributions. Our principal sources of liquidity include cash generated by operating activities,borrowings under the Credit Agreement and issuances of debt and equity securities, including under the DRIP.We believe cash generated by operating activities and, where necessary, borrowings under the Credit Agreement will be sufficient to service our debt, fundworking capital, fund our estimated expansion capital expenditures, fund our maintenance capital expenditures and pay distributions through 2020. Because wedistribute all of our available cash, which excludes prudent operating reserves, we expect to fund any future expansion capital expenditures or acquisitionsprimarily with capital from external financing sources, such as borrowings under the Credit Agreement and issuances of debt and equity securities, including underthe DRIP.To fund a portion of the CDM Acquisition, on March 23, 2018 the Partnership and Finance Corp co-issued $725.0 million in aggregate principal amount of theSenior Notes 2026 and, on the Transactions Date, the Partnership issued the Preferred Units and Warrants for aggregate gross consideration of $500.0 million. Thetransaction fees associated with these issuances were financed with borrowings under the Credit Agreement. Also on the Transactions Date, the borrowing capacityunder the Credit Agreement was increased from $1.1 billion to $1.6 billion. In addition, on March 7, 2019, the Partnership and Finance Corp co-issued $750.0million aggregate principal amount of the Senior Notes 2027 and used the net proceeds to reduce our outstanding borrowings under the Credit Agreement.We are not aware of any regulatory changes or environmental liabilities that we currently expect to have a material impact on our current or future operations.Please see “Capital Expenditures” below.Cash FlowsThe following table summarizes our sources and uses of cash for the years ended December 31, 2019 and 2018 (in thousands): Year Ended December 31, 2019 2018Net cash provided by operating activities$300,580 $226,340Net cash used in investing activities(144,490) (779,663)Net cash provided by (used in) financing activities(156,179) 549,409Net cash provided by operating activities. The $74.2 million increase in net cash provided by operating activities for the year ended December 31,2019 compared to the year ended December 31, 2018 was primarily due to a $58.7 million increase in net income, as adjusted for non-cash items, and changes inother working capital. Net cash used in investing activities. The $635.2 million decrease in net cash used in investing activities for the year ended December 31, 2019 compared tothe year ended December 31, 2018 was primarily due to (1) $1.2 billion of cash paid, offset by $710.5 million of cash assumed, each as part of the CDMAcquisition for the year ended December 31, 2018, (2) a $95.4 million decrease in capital expenditures for purchases of new compression units, related equipmentand reconfiguration costs, (3) a $15.0 million increase in proceeds from disposition of property and equipment and (4) a $3.8 million increase in insurance proceedsreceived during the year ended December 31, 2019 for compression units previously damaged.Net cash provided by (used in) financing activities. Net cash used in financing activities for the year ended December 31, 2019 was $156.2 million comparedto net cash provided by financing activities of $549.4 million for the year ended December 31, 2018. This change was primarily due to (1) $479.1 million of netproceeds received during the year ended December 31, 2018 for the issuance of Preferred Units and Warrants used to partially fund the CDM Acquisition, (2) anincrease of $51.9 million in cash distributions paid on common units, as the USA Compression Predecessor did not pay distributions prior to the TransactionsDate, (3) an increase of $24.5 million of cash distributions paid on Preferred Units as they were not outstanding prior to the Transactions Date, (4) a decrease in netborrowings of $127.3 million for the year ended December 31, 2019, as additional borrowings for the year ended December 31, 2018 were made primarily to payfees and expenses related to the CDM Acquisition, and (5) $28.5 million51Table of Contentsin intercompany contributions received by the USA Compression Predecessor for the year ended December 31, 2018 from its former parent company.Capital ExpendituresThe compression services business is capital intensive, requiring significant investment to maintain, expand and upgrade existing operations. Our capitalrequirements have consisted primarily of, and we anticipate that our capital requirements will continue to consist primarily of, the following:•maintenance capital expenditures, which are capital expenditures made to maintain the operating capacity of our assets and extend their useful lives, toreplace partially or fully depreciated assets, or other capital expenditures that are incurred in maintaining our existing business and related operatingincome; and•expansion capital expenditures, which are capital expenditures made to expand the operating capacity or operating income capacity of assets, includingby acquisition of compression units or through modification of existing compression units to increase their capacity, or to replace certain partially or fullydepreciated assets that were not currently generating operating income.We classify capital expenditures as maintenance or expansion on an individual asset basis. Over the long term, we expect that our maintenance capitalexpenditure requirements will continue to increase as the overall size and age of our fleet increases. Our aggregate maintenance capital expenditures for the yearsended December 31, 2019 and 2018 were $29.6 million and $32.5 million, respectively. We currently plan to spend approximately $32.0 million in maintenancecapital expenditures during 2020, including parts consumed from inventory.Given our growth objectives and anticipated demand from our customers we anticipate that we will continue to make expansion capital expenditures. Withoutgiving effect to any equipment we may acquire pursuant to any future acquisitions, we currently have budgeted between $110.0 million and $120.0 million inexpansion capital expenditures during 2020. Our expansion capital expenditures for the years ended December 31, 2019 and 2018 were $170.3 million and $208.7million, respectively.Revolving Credit FacilityAs of December 31, 2019, we were in compliance with all of our covenants under the Credit Agreement. As of December 31, 2019, we had outstandingborrowings under the Credit Agreement of $402.7 million, $1.2 billion of borrowing base availability and, subject to compliance with the applicable financialcovenants, available borrowing capacity of $484.4 million.As of February 13, 2020, we had outstanding borrowings under the Credit Agreement of $422.5 million. We expect to remain in compliance with ourcovenants under the Credit Agreement throughout 2020. If our current cash flow projections prove to be inaccurate, we expect to be able to remain in compliancewith such financial covenants by taking one or more of the following actions: issue debt and equity securities in conjunction with the acquisition of anotherbusiness; issue equity in a public or private offering; request a modification of our covenants from our bank group; reduce distributions from our currentdistribution rate or obtain an equity infusion pursuant to the terms of the Credit Agreement.For a more detailed description of the Credit Agreement including the covenants and restrictions contained therein, please refer to Note 10 to our consolidatedfinancial statements in Part II, Item 8 “Financial Statements and Supplementary Data”.Senior NotesOn March 7, 2019, the Partnership and Finance Corp co-issued $750.0 million aggregate principal amount of senior notes due on September 1, 2027 (the“Senior Notes 2027”). The Senior Notes 2027 accrue interest from March 7, 2019 at the rate of 6.875% per year. Interest on the Senior Notes 2027 is payablesemi-annually in arrears on each of March 1 and September 1, with the first such payment having occurred on September 1, 2019.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 anequivalent amount of senior notes (“Exchange Notes 2027”) registered under the Securities Act. The Exchange Notes 2027 are substantially identical to the SeniorNotes 2027, except that the Exchange Notes 2027 have been registered with the SEC and do not contain the transfer restrictions, restrictive legends, registrationrights or additional interest provisions of the Senior Notes 2027.52Table of ContentsSee Note 10 to our consolidated financial statements in Part II, Item 8 “Financial Statements and Supplementary Data” for information regarding the SeniorNotes.Distribution Reinvestment PlanDuring the years ended December 31, 2019 and 2018, distributions of $1.0 million and $0.6 million, respectively, were reinvested under the DRIP resulting inthe issuance of 60,584 and 39,280 common units, respectively.Such distributions are treated as non-cash transactions in the accompanying Consolidated Statements of Cash Flows included in Part II, Item 8 “FinancialStatements and Supplementary Data” of this report.See Note 12 to our consolidated financial statements in Part II, Item 8 “Financial Statements and Supplementary Data” for more information regarding theDRIP.Total Contractual Cash ObligationsThe following table summarizes our total contractual cash obligations as of December 31, 2019 (in thousands): Payments Due by PeriodContractual Obligations Total Less than 1 year 1 - 3 years 3 - 5 years More than5 yearsLong-term debt (1) $1,877,722 $— $— $402,722 $1,475,000Interest on long-term debt obligations (2) 807,487 123,253 246,507 208,274 229,453Equipment and capital purchases (3) 49,267 49,267 — — —Operating and finance lease obligations (4) 36,078 5,311 8,587 7,773 14,407Total contractual cash obligations $2,770,554 $177,831 $255,094 $618,769 $1,718,860________________________________(1)We assumed that the amount outstanding under the Credit Agreement at December 31, 2019 would be repaid in April 2023, the maturity date of the facility.

Our revenues and results of operations have not been materially impacted by inflation and changing prices in the past three fiscal years.Off-Balance Sheet ArrangementsWe have no off-balance sheet financing activities. Please refer to Note 17 to our consolidated financial statements in Part II, Item 8 “Financial Statements andSupplementary Data” included in this report for a description of our commitments and contingencies.Critical Accounting Policies and EstimatesThe discussion and analysis of our financial condition and results of operations is based upon our financial statements. These financial statements wereprepared in conformity with GAAP. As such, we are required to make certain estimates, judgments and assumptions that affect the reported amounts of assets andliabilities at the date of the financial statements and the reported amounts of revenue and expenses during the periods presented. We base our estimates onhistorical experience, available information and various other assumptions we believe to be reasonable under the circumstances. On an ongoing basis, we evaluateour estimates; however, actual results may differ from these estimates under different assumptions or conditions. The accounting policies that53Table of Contentswe believe require management’s most difficult, subjective or complex judgments and are the most critical to its reporting of results of operations and financialposition are as follows:Revenue RecognitionWe recognize revenue when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services orgoods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Sales taxes incurred onbehalf of, and passed through to, customers are excluded from revenue. Incidental items, if any, that are immaterial in the context of the contract are recognized asexpense.Contract operations revenueRevenue from contracted compression, station, gas treating and maintenance services is recognized ratably under our fixed-fee contracts over the term of thecontract as services are provided to our customers. Initial contract terms typically range from six months to five years, however we usually continue to providecompression services at a specific location beyond the initial contract term, either through contract renewal or on a month-to-month or longer basis. We primarilyenter into fixed-fee contracts whereby our customers are required to pay our monthly fee even during periods of limited or disrupted throughput. Services aregenerally billed monthly, one month in advance of the commencement of the service month, except for certain customers who are billed at the beginning of theservice month, and payment is generally due 30 days after receipt of our invoice. Amounts invoiced in advance are recorded as deferred revenue until earned, atwhich 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 eachservice contract.Retail parts and services revenueRetail parts and services revenue is earned primarily on freight and crane charges that are directly reimbursable by our customers and maintenance work onunits 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 intime 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 thebenefits 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 due30 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 nomaterial obligations for returns, refunds, or warranties. Our standard contracts do not usually include material variable or non-cash consideration.Business Combinations and GoodwillGoodwill acquired in connection with business combinations represents the excess of consideration over the fair value of net assets acquired. Certainassumptions and estimates are employed in determining the fair value of assets acquired and liabilities assumed. Goodwill is not amortized, but is reviewed forimpairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwillmay not be recovered.Goodwill – Impairment AssessmentsWe evaluate goodwill for impairment annually on October 1 and whenever events or changes indicate that it is more likely than not that the fair value of oursingle business reporting unit could be less than its carrying value (including goodwill). The timing of the annual test may result in charges to our statement ofoperations in our fourth fiscal quarter that could not have been reasonably foreseen in prior periods.We estimate the fair value of our reporting unit based on a number of factors, including the potential value we would receive if we sold the reporting unit,enterprise value, discount rates and projected cash flows. Estimating projected cash flows requires us to make certain assumptions as it relates to future operatingperformance. When considering operating performance, various factors are considered such as current and changing economic conditions and the commodity priceenvironment, among others. Due to the imprecise nature of these projections and assumptions, actual results can, and often do, differ from our estimates. If thegrowth assumptions embodied in the current year impairment testing prove inaccurate, we could incur an impairment charge in the future.As of December 31, 2019, the Partnership had $619.4 million of goodwill, of which $366.0 million was determined as part of the purchase price allocation tothe Partnership’s assets acquired by the USA Compression Predecessor.54Table of ContentsAs of October 1, 2019 and 2018, we performed a qualitative assessment of relevant events and circumstances potentially indicating the likelihood of goodwillimpairment. The qualitative assessment included weighting such factors as (i) macroeconomic conditions, (ii) industry and market considerations, (iii) costfactors, (iv) overall financial performance of the reporting unit, (v) other relevant entity-specific events, and (vi) consideration of whether there was a sustaineddecrease in the price of our units. Upon completion of our qualitative assessment, we concluded that it is not more likely than not that the fair value of our singlereporting unit was less than its carrying value and that our goodwill was not impaired for the years ended December 31, 2019 and 2018.One key assumption for the measurement of goodwill impairment is management’s estimate of future cash flows and EBITDA. These estimates are based onthe annual budget for the upcoming year and forecasted amounts for multiple subsequent years. The annual budget process is typically completed near the annualgoodwill impairment testing date, and management uses the most recent information for the annual impairment tests. The forecast is also subjected to acomprehensive update annually in conjunction with the annual budget process and is revised periodically to reflect new information and/or revised expectations.As discussed above, estimates of fair value can be affected by a variety of external and internal factors. Volatility in crude oil prices can cause disruptions inglobal energy industries and markets. Potential events or circumstances that could reasonably be expected to negatively affect the key assumptions we used inestimating the fair value of our reporting unit include the consolidation or failure of crude oil and natural gas producers, which may result in a smaller market forservices and may cause us to lose key customers, and cost-cutting efforts by crude oil and natural gas producers, which may cause us to lose current or potentialcustomers or achieve less revenue per customer. We continue to monitor the $619.4 million balance of goodwill and if the estimated fair value of our reporting unitdeclines due to any of these or other factors, we may be required to record future goodwill impairment charges.Long-Lived AssetsLong-lived assets, which include property and equipment, and intangible assets, comprise a significant amount of our total assets. Long-lived assets to be heldand used by us are reviewed to determine whether any events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. Forlong-lived assets to be held and used, we base our evaluation on impairment indicators such as the nature of the assets, the future economic benefit of the assets, theconsistency of performance characteristics of compression units in our idle fleet with the performance characteristics of our revenue generating horsepower, anyhistorical or future profitability measurements and other external market conditions or factors that may be present. If such impairment indicators are present orother factors exist that indicate the carrying amount of the asset may not be recoverable, we determine whether an impairment has occurred through the use of anundiscounted cash flows analysis. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the estimated fair valueof the asset. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, is based on an estimate of discountedcash flows, the expected net sale proceeds compared to other similarly configured fleet units we recently sold, a review of other units recently offered for sale bythird parties, or the estimated component value of similar equipment we plan to continue to use.Potential events or circumstances that could reasonably be expected to negatively affect the key assumptions we used in estimating whether or not the carryingvalue of our long-lived assets are recoverable include the consolidation or failure of crude oil and natural gas producers, which may result in a smaller market forservices and may cause us to lose key customers, and cost-cutting efforts by crude oil and natural gas producers, which may cause us to lose current or potentialcustomers or achieve less revenue per customer. If our projections of cash flows associated with our units decline, we may have to record an impairment ofcompression equipment in future periods.For the years ended December 31, 2019 and 2018, we evaluated the future deployment of our idle fleet under then-current market conditions anddetermined to retire and re-utilize key components of 33 and 103 compressor units, respectively, or approximately 11,000 and 33,000 horsepower, respectively,that were previously used to provide services in our business. As a result, we recorded $5.9 million and $8.7 million in impairment of compression equipment forthe years ended December 31, 2019 and 2018, respectively. The primary causes for this impairment were: (i) units were not considered marketable in theforeseeable future, (ii) units were subject to excessive maintenance costs or (iii) units were unlikely to be accepted by customers due to certain performancecharacteristics of the unit, such as the inability to meet then-current quoting criteria without excessive retrofitting costs. These compression units were writtendown to their respective estimated salvage values, if any.Allowances and ReservesWe maintain an allowance for doubtful accounts based on specific customer collection issues and historical experience. The determination of the allowancefor doubtful accounts requires us to make estimates and judgments regarding our customers’ ability55Table of Contentsto pay amounts due. On an ongoing basis, we conduct an evaluation of the financial strength of our customers based on payment history, the overall businessclimate in which our customers operate and specific identification of customer bad debt and make adjustments to the allowance as necessary. Our evaluation of ourcustomers’ financial strength is based on the aging of their respective receivables balance, customer correspondence, financial information and third-party creditratings. Our evaluation of the business climate in which our customers operate is based on a review of various publicly-available materials regarding ourcustomers’ industries, including the solvency of various companies in the industry.Recent Accounting PronouncementsFor discussion on the adoption of Accounting Standards Update 2016-02 Leases and other specific recent accounting pronouncements affecting us, please seeNote 2 and Note 18, respectively, to our consolidated financial statements in Part II, Item 8 “Financial Statements and Supplementary Data”.ITEM 7A.Quantitative and Qualitative Disclosures About MarketRiskCommodity Price RiskMarket risk is the risk of loss arising from adverse changes in market rates and prices. We do not take title to any natural gas or crude oil in connection withour services and, accordingly, have no direct exposure to fluctuating commodity prices. However, the demand for our compression services depends upon thecontinued demand for, and production of, natural gas and crude oil. Sustained low natural gas or crude oil prices over the long term could result in a decline in theproduction of natural gas or crude oil, which could result in reduced demand for our compression services. We do not intend to hedge our indirect exposure tofluctuating commodity prices. A one percent decrease in average revenue generating horsepower during the year ended December 31, 2019 would have resulted ina decrease of approximately $6.6 million and $4.4 million in our revenue and gross operating margin, respectively. Gross operating margin is a non-GAAPfinancial measure. For a reconciliation of gross operating margin to net income (loss), its most directly comparable financial measure, calculated and presented inaccordance with GAAP, please read Part II, Item 6 “Selected Financial Data – Non-GAAP Financial Measures”. Please also read Part I, Item 1A “Risk Factors –Risks Related to Our Business – A long-term reduction in the demand for, or production of, natural gas or crude oil in the locations where we operate couldadversely affect the demand for our services or the prices we charge for our services, which could result in a decrease in our revenues and cash available fordistribution to unitholders”.Interest Rate RiskWe are exposed to market risk due to variable interest rates under our Credit Agreement.As of December 31, 2019, we had approximately $402.7 million of variable-rate outstanding indebtedness at a weighted-average interest rate of 4.31%. A onepercent increase or decrease in the effective interest rate on our variable-rate outstanding debt as of December 31, 2019 would result in an annual increase ordecrease in our interest expense of approximately $4.0 million.For further information regarding our exposure to interest rate fluctuations on our debt obligations, see Note 10 to our consolidated financial statements in PartII, Item 8 “Financial Statements and Supplementary Data”. Although we do not currently hedge our variable rate debt, we may, in the future, hedge all or a portionof such debt.Credit RiskOur credit exposure generally relates to receivables for services provided. If any significant customer of ours should have credit or financial problemsresulting in a delay or failure to repay the amount it owes us, it could have a material adverse effect on our business, financial condition, results of operations orcash flows.ITEM 8.Financial Statements and SupplementaryDataThe financial statements and supplementary information specified by this Item are presented in Part IV, Item 15 “Exhibits and Financial StatementSchedules”.ITEM 9.Changes in and Disagreements With Accountants on Accounting and FinancialDisclosureNone.56Table of ContentsITEM 9A.Controls and ProceduresDisclosure Controls and ProceduresAs required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including ourprincipal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined inRules 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 toprovide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated andcommunicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regardingrequired disclosures, and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon theevaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as ofDecember 31, 2019 at the reasonable assurance level.Management’s Annual Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting for us. Our internal control system wasdesigned 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 possiblecircumvention or overriding of controls. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controlsmust be considered relative to their costs. Management must make judgments with respect to the relative cost and expected benefits of any specific controlmeasure. The design of a control system also is based in part upon assumptions and judgments made by management about the likelihood of future events, andthere 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 overfinancial reporting can provide no more than reasonable assurance with respect to the fair presentation of financial statements and the processes under which theywere prepared.Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, managementused the criteria set forth by the 2013 Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework. Based onthis assessment, our management believes that, as of December 31, 2019, our internal control over financial reporting was effective. Grant Thornton LLP, anindependent registered public accounting firm, has audited the effectiveness of our internal control over financial reporting as of December 31, 2019, as stated intheir report, which is included herein.REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMBoard of Directors of USA Compression GP, LLC andUnitholders of USA Compression Partners, LPOpinion on internal control over financial reportingWe 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, 2019, based on criteria established in the 2013 Internal Control-Integrated Framework issued by the Committee of SponsoringOrganizations of the Treadway Commission (“COSO”). In our opinion, the Partnership maintained, in all material respects, effective internal control over financialreporting as of December 31, 2019, 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 consolidatedfinancial statements of the Partnership as of and for the year ended December 31, 2019, and our report dated February 18, 2020 expressed an unqualified opinionon those financial statements.Basis for opinionThe Partnership’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness ofinternal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is toexpress an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOBand are required to be independent57Table of Contentswith respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and ExchangeCommission 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 reasonableassurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understandingof internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness ofinternal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our auditprovides a reasonable basis for our opinion.Definition and limitations of internal control over financial reportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and thepreparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financialreporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect thetransactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation offinancial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only inaccordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection ofunauthorized 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 ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance withthe policies or procedures may deteriorate./s/ GRANT THORNTON LLPHouston, TexasFebruary 18, 202058Table of ContentsChanges in Internal Control over Financial ReportingThere 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 quarterthat materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.ITEM 9B.Other InformationNone.59Table of ContentsPART IIIITEM 10.Directors, Executive Officers and CorporateGovernanceBoard of DirectorsOur general partner, USA Compression GP, LLC (the “General Partner”), manages our operations and activities. As a result of several transactions (the“Transactions”) that closed on April 2, 2018 (the “Transactions Date”), the General Partner is solely owned by Energy Transfer Operating, L.P. (“ETO”), a whollyowned subsidiary of Energy Transfer LP (“ET” and, collectively with ETO and their affiliates, “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 solemember of the General Partner, ETO is entitled under the limited liability company agreement of the General Partner (the “GP LLC Agreement”) to appoint alldirectors of the General Partner, subject to rights and restrictions contained in other agreements. The GP LLC Agreement provides that the Board shall consist ofbetween two and nine persons, at least two of whom are required to meet the independence standards required of directors who serve on an audit committee of aboard of directors established by the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC thereunder, andby the NYSE pertaining to qualification for service on an audit committee.The Board is comprised of nine members, eight of whom were designated by ETO and one of whom was designated by EIG Management Company, LLC(“EIG Management”) pursuant to that certain Board Representation Agreement among us, the General Partner, Energy Transfer Equity, L.P. (whose wholly ownedsubsidiary, Energy Transfer Partners, L.L.C. acquired the General Partner in the Transactions and subsequently contributed it to ETO in connection with a mergeramong several Energy Transfer entities that closed in October 2018) and EIG Veteran Equity Aggregator, L.P. (along with its affiliated funds, “EIG”) on theTransactions Date in connection with our private placement to EIG and FS Energy and Power Fund (“FS Energy”) of Series A Preferred Units in the Partnership(the “Preferred Units”) and warrants to purchase common units of the Partnership (the “Warrants”). Under the Board Representation Agreement, EIG Managementhas 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 outstandingcommon units (taking into account the common units issuable upon conversion of the Preferred Units and exercise of the Warrants). Three members of the Boardare independent as defined under the independence standards established by the NYSE and the SEC. Although the NYSE does not require a publicly traded limitedpartnership like us to have a majority of independent directors on the Board or to establish a compensation committee or a nominating committee, the Board haselected to have a standing compensation committee (the “Compensation Committee”). We do not have a nominating committee in light of the fact that ETO andEIG 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 ofthe 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 USACompression 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 foridentifying director nominees, nor do we have a formal policy regarding consideration of diversity in identifying director nominees. We believe, however, that theindividuals appointed as directors have experience, skills and qualifications relevant to our business and have a history of service in senior leadership positionswith 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 and William S. Waldheim are independent directors under thestandards established by the NYSE and the Exchange Act. The Board considered all relevant facts and circumstances and applied the independence guidelines ofthe NYSE and the Exchange Act in determining that none of these directors has any material relationship with us, our management, the General Partner or itsaffiliates 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 Unitsand Warrants do not confer voting rights sufficient to participate in the control of the Partnership or influence its management, (ii) the Board RepresentationAgreement does not grant to EIG a sufficient number of seats on the Board to significantly influence or control its decision making or materially influence themanagement 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.60Table of ContentsThe Board’s Role in Risk OversightThe 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 eachregular meeting of the Board, management provides a report of the Partnership’s operational and financial performance, which often prompts questions andfeedback from the Board. The audit committee of the Board (the “Audit Committee”) provides additional risk oversight through its quarterly meetings, where itdiscusses policies with respect to risk assessment and risk management, reviews contingent liabilities and risks that may be material to the Partnership and assessesmajor legislative and regulatory developments that could materially impact the Partnership’s contingent liabilities and risks. The Audit Committee is also requiredto discuss any material violations of our policies brought to its attention on an ad hoc basis. Additionally, the Compensation Committee reviews our overallcompensation 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 DirectorsAudit Committee. The Board appoints the Audit Committee, which is comprised solely of directors who meet the independence and experience standardsestablished by the NYSE and the Exchange Act. The Audit Committee consists of Messrs. Hartman, Joyce and Waldheim, and Mr. Waldheim serves as chairmanof 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 and Waldheim is “independent” within the meaning of the applicable NYSE and Exchange Act rules governing auditcommittee independence. The Audit Committee assists the Board in its oversight of the integrity of our financial statements and our compliance with legal andregulatory requirements as well as the effectiveness of our corporate policies and internal controls. The Audit Committee has the sole authority to retain andterminate our independent registered public accounting firm, approve all auditing services and related fees and the terms thereof, and pre-approve any non-auditservices to be rendered by our independent registered public accounting firm. The Audit Committee is also responsible for confirming the independence andobjectivity of our independent registered public accounting firm. Our independent registered public accounting firm is given unrestricted access to the AuditCommittee.The charter of the Audit Committee (the “Audit Committee Charter”) is available under the Investor Relations tab on our website at usacompression.com.

The NYSE does not require a listed limited partnership like us to have a compensation committee. However, the Board establishedthe Compensation Committee to, among other things, oversee our compensation program described below in Part III, Item 11 “Executive Compensation.” TheCompensation Committee consists of Messrs. Joyce and Waldheim and is chaired by Mr. Joyce. The Compensation Committee establishes and reviews generalpolicies related to our compensation and benefits and is responsible for making recommendations to the Board with respect to the compensation and benefits of theBoard. In addition, the Compensation Committee administers the USA Compression Partners, LP 2013 Long-Term Incentive Plan, as amended and as may befurther 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 Committeemay not be an officer of or employed by the General Partner, us or our subsidiaries. During 2019, neither Mr. Joyce nor Mr. Waldheim was an officer or employeeof 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’sboard of directors. In addition, neither Mr. Joyce nor 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 theCompensation 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 Boardwill appoint independent directors and which may be asked to review specific matters that the Board believes may involve conflicts of interest between us, ourlimited 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. Themembers of the conflicts committee may not be officers or employees of the General Partner or directors, officers or employees of its affiliates, including EnergyTransfer, and must meet the independence and experience standards established by the NYSE and the Exchange Act to serve on the Audit Committee, and certainother requirements. Any matters approved by the conflicts committee in good faith will be conclusively deemed to be fair and reasonable to us, approved by all ofour partners and not a breach by the General Partner of any duties it may owe us or our unitholders.61Table of ContentsCorporate Governance Guidelines and Code of EthicsThe Board has adopted Corporate Governance Guidelines (the “Guidelines”) that outline important policies and practices regarding our governance andprovide 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”) thatapplies to the General Partner and its subsidiaries and affiliates, including us, and to all of its and their directors, employees and officers, including its principalexecutive officer, principal financial officer and principal accounting officer.

To our knowledge and based solely on a review of Section 16(a) forms filedelectronically with the SEC, we believe that all reporting obligations of the members of the Board, our executive officers and greater than 10 percent unitholdersunder Section 16(a) were satisfied during the year ended December 31, 2019, with the exception of one late Form 3 filing on behalf of Mr. Whitehurst.Common Unit Ownership by Directors and Executive OfficersWe encourage our directors and executive officers to invest in and retain ownership of our common units, but we do not require such individuals to establishand 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 itsaffiliates for all expenses incurred on our behalf, including the compensation of employees of the General Partner or its affiliates that perform services on ourbehalf. These expenses include all expenditures necessary or appropriate to the conduct of our business and that are allocable to us. The Second Amended andRestated Agreement of Limited Partnership of USA Compression Partners, LP (the “Partnership Agreement”) provides that the General Partner will determine ingood 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 forcompensation or expenses incurred on our behalf.ITEM 11.Executive CompensationAs is commonly the case with publicly traded limited partnerships, we have no officers, directors or employees. Under the terms of the PartnershipAgreement, we are ultimately managed by the General Partner, which is controlled by Energy Transfer. All of our employees, including our executive officers, areemployees of USA Compression Management Services, LLC (“USAC Management”), a wholly owned subsidiary of the General Partner. References to “ourofficers” and “our directors” refer to the officers and directors of the General Partner.65Table of ContentsCompensation Discussion & AnalysisNamed Executive OfficersThe following disclosure describes the executive compensation program for the named executive officers identified below (the “NEOs”). For the year endedDecember 31, 2019, the NEOs were:•Eric D. Long, President andCEO;•Matthew C. Liuzzi, Vice President, Chief Financial Officer andTreasurer;•William G. Manias, Vice President and Chief OperatingOfficer;•David A. Smith, Vice President and President, Northeast Region;and•Sean T. Kimble, Vice President, HumanResources.Compensation Philosophy and ObjectivesSince our initial public offering in 2013, we have consistently based our compensation philosophy and objectives on the premise that a significant portion ofeach NEO’s total compensation should be incentive-based or “at-risk” compensation. We share Energy Transfer’s philosophy that the NEOs’ total compensationlevels should be competitive in the marketplace for executive talent and abilities. The Compensation Committee generally targets at or near the 50th percentile ofthe market for the three main components of our compensation program: base salary, annual discretionary cash bonus and long-term equity incentive awards. TheCompensation Committee believes the incentive-based balance is achieved by (i) the payment of annual discretionary cash bonuses that consider (a) theachievement of the financial performance objectives for a fiscal year set at the beginning of such fiscal year and (b) the individual contributions of each of theNEOs to our level of success in achieving the annual financial performance objectives, and (ii) the annual grant of time-based restricted phantom unit awardsunder 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 themarket 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 2019 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 comprisedof base salary. Our compensation program is structured to achieve the following:•compensate executives with an industry-competitive total compensation package of competitive base salaries and significant incentive opportunitiesyielding a total compensation package 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 thoseof their counterparts at similarly situated companies;•motivate executive officers and key employees to achieve strong financial and operationalperformance;•emphasize performance-based or “at risk” compensation;and66Table of Contents•reward individual performance.Methodology to Setting Compensation PackagesOur executive compensation program is administered by the Compensation Committee. The Compensation Committee considers market trends incompensation, including the practices of identified competitors, and the alignment of the compensation program with the Partnership’s strategy. Specifically, forthe NEOs, the Compensation Committee:•establishes and approves target compensation levels for eachNEO;•approves Partnership performance measures andgoals;•determines the mix between cash and equity compensation, short-term and long-term incentives andbenefits;•verifies the achievement of previously established performance goals; and•approves the resulting cash or equity awards to theNEOs.The Compensation Committee also considers other factors such as the role, contribution and performance of an individual relative to his or her peers at thePartnership. The Compensation Committee does not assign specific weight to these factors, but rather makes a subjective judgment taking all of these factors intoaccount.The Compensation Committee reviews and approves all compensation for the NEOs. In determining the compensation for the NEOs, the CompensationCommittee takes into account input from the CEO for the compensation of the other NEOs. The CEO considers comparative compensation data and evaluates theindividual performance of each NEO and their respective contributions to the Partnership. The recommendations are then reviewed by the CompensationCommittee, which may accept the recommendations or make adjustments to the recommended compensation based on the Compensation Committee’s assessmentof the individual’s performance and contributions to the Partnership. The CEO’s compensation is reviewed and approved by the Compensation Committee basedon 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 ofthe NEOs against data for compensation levels for specific executive positions reported in published executive compensation surveys within each of the (i) energyindustry and (ii) overall market. The Compensation Committee also reviews publicly filed peer group executive compensation disclosures pertaining to certainexecutive roles, but because of limited sample size due to the relatively small number of publicly traded natural gas compression companies, the CompensationCommittee 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 peercompanies to assist in setting compensation levels for our executives, including the NEOs. In light of the Transactions and resulting increased size of thePartnership and greater level of responsibility for each of the NEOs, in May 2018 the Compensation Committee engaged Longnecker & Associates(“Longnecker”), who is also the independent compensation advisor to Energy Transfer, to provide an updated targeted market review and benchmarking forcertain members of our senior leadership team (the “2018 Longnecker Report”). The Compensation Committee relied on the results of the 2018 Longnecker Reportfor determinations of base salary, bonus and general compensation items for 2019 for the NEOs.The Compensation Committee also engaged Longnecker to conduct a new report in the latter part of the 2019 year that provided the Compensation Committeewith assistance in setting NEO compensation for the 2020 year (the “2019 Longnecker Report”). The Compensation Committee did not make long-term incentivecompensation decisions until October of 2019, therefore the Compensation Committee used the 2019 Longnecker Report when determining the number of equityawards that should be granted to our NEOs in December 2019.In connection with its engagement of Longnecker in both 2018 and 2019, based on the information presented to it, the Compensation Committee assessed theindependence of Longnecker under applicable SEC and NYSE rules and concluded that Longnecker’s work for the Compensation Committee did not raise anyconflicts of interest.67Table of ContentsOur peer group selected by the Compensation Committee in consultation with Longnecker included the following companies for the 2018 Longnecker Report:Company Ticker1.

Tallgrass Energy Partners, LP TEP14. TETRA Technologies, Inc. TTIElements of the Compensation ProgramCompensation for the NEOs consists primarily of the following elements and corresponding objectives:Compensation Element Primary ObjectiveBase salary To recognize performance of job responsibilities and to attract and retainindividuals with superior talent. Annual incentive compensation To promote near-term performance objectives and reward individualcontributions to the achievement of those objectives. Long-term equity incentive awards To emphasize long-term performance objectives, encourage the maximization ofunitholder value and retain key executives by providing an opportunity toparticipate 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 providingbenefits comparable to those offered by similarly situated companies.Base Salary for 2019Base salaries for the NEOs have generally been set at a level deemed necessary to attract and retain individuals with superior talent. Base salary increases aredetermined based upon the job responsibilities, demonstrated proficiency and performance of the NEO and market conditions. In connection with determining basesalaries for each of the NEOs for 2019, the Compensation Committee and CEO utilized the 2018 Longnecker Report to determine comparable salaries for suchexecutive roles within our peer group, and determined that the NEOs’ base salaries were generally in line with the market, and no material changes were neededfor the 2019 year.68Table of ContentsThe 2019 base salaries (and 2018 base salaries, for comparison purposes) for the NEOs, including our CEO, are set forth in the following table:Name and Principal Position 2019 Base Salary ($) 2018 Base Salary ($)Eric D.

Kimble, Vice President, Human Resources 307,670 307,670Annual Cash Incentive Compensation for 2019In February 2019, the Compensation Committee made several modifications to the Partnership’s previous annual cash incentive program and approved theUSA Compression Partners, LP Amended and Restated Annual Cash Incentive Plan (the “Bonus Plan”), which was effective for fiscal year 2019. Each of theNEOs is entitled to participate in the Bonus Plan and their potential bonus is governed by the Bonus Plan and, for Messrs. Smith and Kimble, also governed by theirrespective employment agreements. The Compensation Committee acts as the administrator of the Bonus Plan under the supervision of the full Board, and has thediscretion to amend, modify or terminate the Bonus Plan at any time.In February 2020, the Compensation Committee determined whether to make annual cash bonus awards to executives, including the NEOs, under the BonusPlan attributable to the year ended December 31, 2019. Although the Bonus Plan is generally based upon our satisfaction of certain performance measures thatwere pre-determined for the 2019 year, the Compensation Committee does retain the authority to use its business judgement to make decisions or adjustments tothe Bonus Plan’s funding pool or the individual bonus awards resulting from the guidelines set forth below. The Bonus Plan contains four payout factors andcorresponding percentages that comprise the total annual target bonus for all eligible employees, including the NEOs (the “Annual Target Bonus Pool”): (i) theAdjusted EBITDA Budget Target Factor (the “Adjusted EBITDA Factor”): 30%; (ii) the Distributable Cash Flow Budget Target Payout Factor (the “DCFFactor”): 30%; (iii) the Leverage Ratio Budget Target Factor (the “Leverage Ratio Factor”): 30% and (iv) the Safety Budget Target Payout Factor (the “SafetyFactor”): 10%.Each of the Adjusted EBITDA Factor and DCF Factor assign payout factors from 0% to 120% based on the percentage of the Partnership’s budgetedAdjusted 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 FactorGreater than or equal to 110% 1.20x109.9%-105.0% 1.10x104.9%-95.0% 1.00x94.9%-90.0% 0.90x89.9%-80.0% 0.75xLess than 80.0% 0.00xFor the 2019 year, the Compensation Committee set the Adjusted EBITDA Budget Target at $402,958,000 and the DCF Budget Target at $207,750,000.69Table of ContentsThe Leverage Ratio Factor assigns payout factors based on the Partnership’s achievement of its budgeted Leverage Ratio (as defined in the Partnership’s SixthAmended and Restated Credit Agreement, provided that, for the purposes of calculating the Leverage Ratio for the Bonus Plan, EBITDA attributable to the fullplan year shall be used in lieu of any other time period) for the year, as shown in the following chart.Leverage Ratio FactorRange within Budget Target Bonus Pool Payout FactorMore than 0.250 below budget target 1.20x0.250-0.125 below 1.10x0.124 below-0.125 above 1.00x0.126-0.375 above 0.70x0.376-0.500 above 0.50xGreater than 0.500 above 0.00xFor the 2019 year, the Compensation Committee set the Leverage Ratio Budget Target at 4.89x.The Safety Factor assigns payout factors based on the Partnership’s Total Recordable Incident Rate, or TRIR (as calculated by the U.S. Occupational Safetyand Health Administration) against the Partnership’s TRIR target, as shown in the following chart.Safety Factor% of Target Bonus Pool Payout FactorLess than 100% 1.00x100%-105% 0.90x105.1%-110% 0.80x110.1%-115% 0.70x115.1%-125% 0.60xGreater than 125% 0.00xFor the 2019 year, the Compensation Committee set the Safety Target at 1.20.The establishment and amount of the Funded Bonus Pool is 100% discretionary and subject to approval and/or adjustment by the Compensation Committee. Indetermining bonuses for the NEOs, the Compensation Committee takes into account whether the Partnership achieved or exceeded its targeted performanceobjectives. In the case of the NEOs, their bonus pool targets range from 60% to 125% of their respective annual base earnings (which amount reflects the actualbase salary earned during the calendar year to reflect periods before and after any base salary adjustment).For the 2019 year, the Compensation Committee set a target bonus amount (the “Target Bonus”) for each NEO prior to the first quarter of the year, which wasset as a percentage of the NEO’s base salary. For the bonus applicable to the 2019 year, the Target Bonus, as a percentage of base salary and as a dollar amount, isreflected in the table below.Name Percentage of BaseSalary Amount ($)Eric D.

For the year ended December 31,2019, we achieved (i) Adjusted EBITDA of $419,640,027, resulting in an Adjusted EBITDA Bonus Pool Payout Factor of 1.00; (ii) DCF of $221,867,965,resulting in a DCF Bonus Pool Payout Factor of 1.10; (iii) Leverage Ratio, as calculated for the purposes of the Bonus Plan, of 4.56, resulting in a Leverage RatioBonus Pool Payout Factor of 1.20; and (iv) a TRIR of 0.84 resulting in a Safety Bonus Pool Payout Factor of 1.00.

Smith 338,398Sean T. Kimble 268,288Long-Term Equity Incentive Awards The Board adopted the LTIP, which is designed to promote our interests, as well as the interests of our unitholders, by rewarding our officers, directors andcertain of our employees for delivering desired performance results, as well as by strengthening our ability to attract, retain and motivate qualified individuals toserve as officers, directors and employees. The LTIP provides for the grant, from time to time at the discretion of the Board, of unit awards, restricted units,phantom units, unit options, unit appreciation rights, distribution equivalent rights (“DERs”) and other common unit-based awards, although since our initial publicoffering in 2013 the Board has only granted awards of phantom units with DERs under the LTIP (the “Phantom Units”). The outstanding, unvested phantom unitsgranted under the LTIP and held by the NEOs are reflected below in “—Outstanding Equity Awards as of December 31, 2019.”On November 1, 2018, following the Transactions, the Board adopted a new form of employee Phantom Unit award agreement under the LTIP (the “PhantomUnit Agreement”) to bring our long-term equity incentive compensation program in line with Energy Transfer’s practices. The Phantom Unit Agreement (i) alteredthe vesting schedule of our time-based Phantom Units from three equal annual installments to incremental vesting over five years (60% on the third December 5following 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 theevent of a Change in Control (as defined under the LTIP and set forth below under “Potential Payments upon Termination or Change in Control”).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 ofthe December 2019 grants of phantom units to the NEOs, the Compensation Committee, in consultation with Longnecker and taking into account internalcompensation levels within Energy Transfer, determined each of the NEOs’ long-term incentive targets. Due to the fact that determinations were made in late2019, the base salaries used for these calculations were the base salaries set for the 2020 calendar year. Each NEO’s grant value is shown in the following table:Long-Term Incentive Target Amounts for the Year Ended December 31, 2019Name Percentage ofBase Salary Grant Date Amount($)Eric D. Long 400% 2,656,200Matthew C. Liuzzi 250% 1,030,000William G. Manias 225% 1,012,961David A. Smith 94% 500,000Sean T. Kimble 175% 554,575Under the LTIP, the Compensation Committee has the discretion to determine whether any portion of phantom units should be settled in cash upon vesting forthe purpose of conserving common units approved for issuance under the LTIP. On February 13, 2019, the Compensation Committee approved the defaultsettlement 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) and50% in common units for all vesting of phantom units occurring during 2019. However, the Compensation Committee also specified that if an employeeaffirmatively requests in writing that the percentage of cash settlement be set at a specific amount that is less than 50% (and such71Table of Contentsemployee 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 thePartnership 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 anamount 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 therecord date for the distribution on the Partnership’s common units for such quarter and (b) the quarterly distribution with respect to the Partnership’s commonunits. 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 recipientcommitted certain acts of misconduct, as more particularly described in the LTIP.Retention Phantom Unit AwardsOn October 29, 2019, the Compensation Committee approved a grant of Phantom Units (the “Retention Units”), which occurred on December 5, 2019, in thefollowing amounts: (i) 41,764 Retention Units to Mr. Long; and (ii) 25,911 Retention Units to Mr. Liuzzi, and were made pursuant to Retention Phantom UnitAgreements (the “Retention Agreements”), the form of which was approved by the Compensation Committee on November 1, 2018, entered into between thePartnership and each of Messrs. Long and Liuzzi. The Retention Units will vest incrementally, with 60% of the Retention Units vesting on December 5, 2022 and40% of the Retention Units vesting on December 5, 2024, subject in each case to the NEO’s continued employment with the Partnership. Each Retention Unit wasgranted with a corresponding DER.The Compensation Committee approved the grant of Retention Units in recognition of the importance of Messrs. Long and Liuzzi to the Partnership’s long-term success and to encourage their retention by providing additional time-based compensation. 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 PerquisitesWe provide the NEOs with certain personal benefits and perquisites, which we do not consider to be a significant component of our overall executivecompensation program, but which we recognize are an important factor in attracting and retaining talented executives. The NEOs are eligible under the same plansas all other employees with respect to our medical, dental, vision, disability and life insurance benefits and a defined contribution plan that is tax-qualified underSection 401(k) of the Internal Revenue Code (the “401(k) Plan”). In addition, we currently provide one or more NEOs with (i) an annual automobile allowance;(ii) club memberships; (iii) personal administrative support; and (iv) personal tax support. The Compensation Committee has determined it is appropriate to offerthese perquisites in order to provide compensation opportunities competitive with those offered by similarly situated public companies. In determining thecompensation 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 notmaterially influence the Compensation Committee’s decision making with respect to other elements of the total compensation to which the NEOs are entitled orwhich they are awarded. The value of personal benefits and perquisites we provided to each of the NEOs in 2019 is set forth below in “-Summary CompensationTable.”Employment AgreementsEach of Messrs. Smith and Kimble is party to an employment agreement with us (together, the “Employment Agreements”), each of which have beenextended 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 atleast 90 days prior to the end of the current employment term. Please see the description of the Employment Agreements under “Potential Payments uponTermination or Change in Control” for further details on the terms of the Employment Agreements.Each of Messrs. Long, Liuzzi and Manias entered into a Termination Agreement and Mutual Release with USAC Management (and, with respect to Mr. Long,USA Compression Partners, LLC) providing for (i) the termination, effective as of November 1, 2018, of the employment agreements to which each of Messrs.Long, Liuzzi and Manias had been party and (ii) a mutual release by each party to the other(s) of all obligations, claims and causes of action arising under theapplicable employment agreement.72Table of ContentsRisk Assessment Related to Our Compensation StructureWe believe our compensation program for all of our employees, including the NEOs, is appropriately structured and not reasonably likely to result in materialrisk 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 resultsor 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 encourageexcessive risk-taking. Furthermore, all business groups and employees receive the same core compensation components of base pay and short-term incentives. Wetypically 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 awardsbecause 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 long-term incentive awards ensures that our employees’ interests align with those of our unitholderswith respect to our long-term performance.Accounting and Tax ConsiderationsWe account for the equity compensation expense for equity awards granted under our LTIP in accordance with U.S. generally accepted accounting principles,which requires us to estimate and record an expense for each equity award over the vesting period of the award. Phantom Units are accounted for as a liability andare 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 independentdirectors do not have a cash settlement option; therefore we account for these awards as equity. During the requisite service period, compensation cost isrecognized 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”) does not applyto the compensation paid to the NEOs and, accordingly, the Compensation Committee did not consider its impact in making the compensation recommendationsdiscussed above.Compensation Committee Interlocks and Insider ParticipationWe do not have any Compensation Committee interlocks. Messrs. Joyce and Waldheim are the only members of the Compensation Committee, and during2019 neither Mr. Joyce nor Mr. Waldheim was an officer or employee of Energy Transfer or any of its affiliates, or served as an officer of any company withrespect to which any of our executive officers served on such company’s board of directors. In addition, neither Mr. Joyce nor Mr. Waldheim is a former employeeof Energy Transfer or any of its affiliates.Compensation Committee ReportThe Compensation Committee has reviewed and discussed the section of this report entitled “Compensation Discussion and Analysis” with management of thePartnership and approved its inclusion in this Annual Report on Form 10-K.Compensation CommitteeGlenn E.

In the event of the NEO’sdeath 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” means an involuntary termination for any reason, including a failure to renew theemployment agreement at the end of an initial term or any renewal term, other than a termination for “Cause.” “Cause” is defined in the Employment Agreementsto mean (i) any material breach of the Employment Agreement, including the material breach of any representation, warranty or covenant made under theEmployment 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 ormisconduct, 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 isdemonstrably and significantly injurious to the Company or any of its affiliates, (iii) conviction of a felony or crime involving moral turpitude, (iv) the NEO’swillful and continued failure or refusal to perform substantially the NEO’s material obligations pursuant to the Employment Agreement or follow any lawful andreasonable directive from the CEO or the Board, other than as a result of the NEO’s incapacity, or (v) a violation of federal, state or local law or regulationapplicable 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 materialagreement 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 ofthe Company, (iii) a material reduction in the NEO’s duties, authority, responsibilities, job title or reporting relationships, (iv) a material reduction by the Companyin 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 ofthe 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 employmentas of the Effective Date of the Employment Agreement.Change in Control Benefits – LTIPOn November 1, 2018, the Board adopted the Phantom Unit Agreement, which (i) provides for incremental vesting of Phantom Units over five years (60% onthe 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, unvestedPhantom Units in the event 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 thePhantom Unit Agreement, if the NEO is at least 65 at the time of his voluntary retirement, 60% of his then-unvested Phantom Units will be forfeited, and theremainder will vest, at the time of retirement. If the NEO is over age 68 at the time of his retirement, 50% of his then-unvested Phantom Units will be forfeited, andthe remainder will vest, at the time of retirement.Prior to November 1, 2018, we had historically included double-trigger change in control provisions for our outstanding LTIP awards, such that in order foraccelerated vesting of phantom units to occur in connection with a change in control, such change in control must be followed by a termination of employment bythe Company without Cause or by the NEO with Good Reason (each as defined in the applicable phantom unit award agreement). Under the LTIP awardagreements entered into prior to the Transactions, in the event of cessation of the NEO’s service for any reason that is not in connection with a change in controltransaction, all Phantom Units that have not vested prior to or in connection with such cessation of service shall automatically be forfeited. However, because theagreements contained the double-trigger vesting provisions described below, and the Transactions were deemed to satisfy the first trigger of a change in controltransaction, a termination by the Company without Cause or by the NEO for Good Reason following the Transactions would result in the acceleration of thePhantom Units granted prior to the Transactions.79Table of ContentsA “Change in Control” is defined under the LTIP as follows:(a)with respect to Awards granted before April 3, 2018, the occurrence of any of the following events: (i) any “person” or “group” within the meaning ofSections 13(d) and 14(d)(2) of the Exchange Act, other than the Company, Riverstone Holdings LLC or an Affiliate of the Company (as determined immediatelyprior to such event) or Riverstone Holdings LLC, shall become the beneficial owner, by way of merger, consolidation, recapitalization, reorganization orotherwise, 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 Partnershipapprove, 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 thePartnership of all or substantially all of its assets in one or more transactions to any Person other than the Company, the Partnership, Riverstone Holdings LLC oran Affiliate of the Company, the Partnership or Riverstone Holdings LLC; or (iv) a transaction resulting in a Person other than the Company, Riverstone HoldingsLLC or an Affiliate of the Company (as determined immediately prior to such event) or Riverstone Holdings LLC being the sole general partner of the Partnership;and(b)with respect to Awards granted on or after April 3, 2018, means the occurrence of any of the following events: (i) any “person” or “group” within themeaning of Sections 13(d) and 14(d)(2) of the Exchange Act, other than the Company, Energy Transfer LP, a Delaware limited partnership (“ET”), EnergyTransfer Operating, L.P., a Delaware limited partnership (“ETO”), an Affiliate of the Company (as determined immediately prior to such event), or an Affiliate of,or successor to, ET or ETO, shall become the beneficial owner, by way of merger, consolidation, recapitalization, reorganization or otherwise, of 50% or more ofthe 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 oftransactions, 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 allof its assets in one or more transactions to any Person other than the Company, the Partnership, ET, ETO, an Affiliate of the Company (as determined immediatelyprior to such event), the Partnership, or an Affiliate of, or successor to, ET or ETO; or (iv) a transaction resulting in a Person other than the Company, ET, ETO, an Affiliate of the Company (as determined immediately prior to such event), or an Affiliate of, or successor to, ET or ETO being the sole general partner of thePartnership.However, if an LTIP award is subject to section 409A of the Internal Revenue Code, a “Change in Control” will be defined in accordance with section 409Aof the Internal Revenue Code and the regulations promulgated thereunder.Potential Payments upon Termination or Change in ControlExcept as otherwise noted, the values in the table below assume that a Change in Control occurred on December 31, 2019 and/or that the NEO’s employmentterminated on that date, as applicable. The amounts actually payable to any NEO can only be calculated with certainty upon actual termination or a Change inControl. The value of the acceleration of the LTIP awards was calculated using the value of $18.14, which was the closing price of the Partnership’s common unitson December 31, 2019.80Table of ContentsExecutive Benefits andPayments Change in Controlfollowed bytermination without“Cause” or for“Good Reason”($) (2) Termination ofEmployment without“Cause” or for“Good Reason”($) (2) Termination ofEmployment becauseof Deathor Disability($) (3) Termination by theExecutive Other Thanfor“Good Reason”($) (4) ContinuedEmploymentFollowing Change ofControl($) (5)Eric D.

Smith and Kimble represents his annualized rate of pay as of December 31, 2019, plus, with respect to the first three columns of thetable, his accrued but unused paid time off as of December 31, 2019. The listed bonus amount for each of Messrs. Smith and Kimble is his bonus awarded with respect tothe year ended December 31, 2019. Because the assumed termination date for each NEO is December 31, 2019, no pro rata bonus amounts based on a partial year ofcontinued employment prior to termination are included. The amount shown for each of Messrs. Long, Liuzzi and Manias represents the amount of earned but unpaid basesalary he would be entitled to receive.81Table of Contents(2)The Employment Agreements for each of Messrs. Smith and Kimble provide that upon termination by the Company without Cause or by the NEO for Good Reason, theNEO is entitled to receive one times his base salary, payable in equal semimonthly installments over the course of one year (or, if such termination occurs within two yearsafter a “change in control event” within the meaning of Treasury Regulation 1.409A-3(i)(5), in a lump sum within 30 days of termination of employment).(3)Upon the death or Disability of Mr. Kimble or Mr. Smith during the Severance Period (as defined in the Employment Agreements), his salary payment will be acceleratedand he (or his estate) will be entitled to the same bonus payment as if the death or Disability had not occurred.(4)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.(5)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 isassumed 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 Changein 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 orhealth 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 outstandingequity at the time of a Change of Control have been reflected.(6)In the event of Mr. Smith’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 entitledto continued health insurance benefits for a period of 24 months following his Separation from Service (the “Coverage Period”), as follows: (i) for the first twelve monthsof 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 theCompany’s group health plan, as in effect at the time of the NEO’s Separation from Service) (ii) for the following six months of the Coverage Period, such health insurancecoverage will be at the NEO’s sole expense; and (iii) for the final six months of the Coverage Period, the Company will be responsible for the proportion of the cost ofsuch 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 Companycovered during the first 12 months of the Coverage Period. The amount shown represents the Company’s contribution to the NEO’s health insurance benefits during thefirst half of the Coverage Period. Messrs. Long, Liuzzi and Manias are not currently party to any contractual arrangements providing for continued health insurancecoverage by the Company following a termination of employment.(7)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 inconnection with such cessation of service shall be automatically forfeited. Notwithstanding the foregoing, with respect to the Phantom Units granted on December 5, 2018and on December 5, 2019, if the NEO retires after attaining the age of 65, 60% of his then-unvested Phantom Units will be forfeited, and the remainder will vest, at thetime of retirement. For the Phantom Units granted on December 5, 2018 and on December 5, 2019, if the NEO is over age 68 at the time of retirement, 50% of his then-unvested Phantom Units will be forfeited, and the remainder will vest, at the time of retirement. For the Phantom Units granted on December 5, 2018 and on December 5,2019, in the event of the death or Disability of the NEO, 100% of the then-unvested Phantom Units shall vest in full immediately prior to such cessation of service due todeath or Disability. In the event of a Change in Control (as defined under the LTIP), 100% of the NEO’s outstanding, unvested Phantom Units granted on December 5,2018 and on December 5, 2019 would vest. As noted above, the Phantom Units granted prior to the Transactions contained a double-trigger change in control provision,and the Transactions satisfied the first trigger, therefore they could become vested upon a termination by the Company without Cause or by the NEO without Good Reasonthat occurred on December 31, 2019.(8)The Retention Agreements for Messrs. Long, Liuzzi and Manias provide that 100% of the outstanding, unvested Retention Units held by the applicable NEO will vestimmediately 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 GoodReason, (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, if he is at the timeof 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.(9)For Messrs. Long, Liuzzi and Manias, provided that the NEO executes and does not revoke a general release and waiver of claims, the NEO will be entitled to a severancepayment intended to capture the value of future distributions associated with Retention Units forfeited for tax withholding purposes.CEO Pay RatioSection 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 certaininformation 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 payratio rules. Rather than providing a pay ratio disclosure that contemplates no employees, we have determined that the disclosure that would be most aligned withthe 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 employeefrom the USAC Management employee population. All references to “our” employees within this section shall refer to the applicable USAC Managementemployees.82Table of ContentsFor 2019, our last completed fiscal year:•The median of the annual total compensation of all employees (other than the CEO) was $118,073.•The annual total compensation of our CEO, as reported in the Summary Compensation Table included elsewhere within this Form 10-K, was$5,459,946.•Based on this information, for 2019 the ratio of the annual total compensation of Mr. Long to the median of the annual total compensation of allemployees was reasonably estimated to be 46.2 to 1.To identity the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employeeand our CEO, we took the following steps:•We determined that, as of December 31, 2019, our employee population consisted of approximately 879 individuals with all of these individuals locatedin the United States (as reported in Part I, Item 1 “Business”, above). This population consisted of our full-time, as we do not have any part-time,temporary employees, or seasonal workers.•We selected December 31, 2019 as our identification date for determining our median employee because it enabled us to make such identification in areasonably 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 2019.•We identified our median employee by consistently applying this compensation measure to all of our employees included in our analysis. Since all of ouremployees, including our CEO, are located in the United States, 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 2019 year in accordance with therequirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $118,073. The difference between such employee’s totalW-2 earnings and the employee’s annual total compensation represents the estimated value of the employee’s net health care benefits (estimated at $4,115per employee), the employer’s 401(k) matching contribution (estimated at $5,194 per employee) and the employee’s 401(k) contribution (estimated at$18,698 per employee).•With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2019 Summary Compensation Tableincluded in this Form 10-K.Director Compensation For the year ended December 31, 2019, our CEO was the only NEO who also served as a director, and he did not receive additional compensation for hisservice on the Board. Mr. Eric Long’s compensation as an NEO is reflected in the Summary Compensation Table above. Officers, employees or paid consultantsor advisors of us or the General Partner or its affiliates who also serve as directors do not receive additional compensation for their service as directors. Other thanMr. Hartman, our directors who are not officers, employees or paid consultants or advisors of us or the General Partner or its affiliates receive cash and equitybased compensation for their services as directors. Our director compensation program is subject to revision by the Board from time to time.The following table shows the total fees earned and other compensation paid in cash to each independent director during 2019.Name FeesPaid in Cash($) Unit Awards($) (1) All OtherCompensation($) (2) Total($)Matthew S.

The directors and officers of the General Partner have fiduciary duties to managethe 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 mannerbeneficial 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, theGeneral Partner will resolve that conflict. The Partnership Agreement contains provisions that modify and limit the General Partner’s fiduciary duties to thePartnership’s unitholders. The Partnership Agreement also restricts the remedies available to the Partnership’s unitholders for actions taken by the General Partnerthat, 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 tous 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 theGeneral Partner is not obligated to seek such approval; (b) approved by the vote of a majority of our outstanding common units, excluding any common unitsowned 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 particularlyfavorable or advantageous to us.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 situationinvolving 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 approvalfrom 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 thestandards 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 theresolution of a conflict is specifically provided for in the Partnership Agreement, the General Partner or the conflicts committee may consider any factors that itdetermines in good faith to be appropriate when resolving a conflict. When the Partnership Agreement provides that someone act in good faith, it requires thatperson 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 TransactionsIf a conflict or potential conflict of interest arises between the General Partner and its affiliates, including Energy Transfer, on the one hand and thePartnership and its limited partners, on the other hand, the resolution of any such conflict or potential conflict is addressed as described under “Conflicts ofInterest.”Pursuant to the Partnership’s Code of Business Conduct and Ethics and Corporate Governance Guidelines, directors, officers and employees are required todisclose 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 orthe Board, as appropriate.Director IndependencePlease see Part III, Item 10 “Directors, Executive Officers and Corporate Governance – Board of Directors” for a discussion of director independence matters.88Table of ContentsITEM 14.Principal Accountant Fees and ServicesThe following table sets forth fees paid for professional services rendered by Grant Thornton LLP (“Grant Thornton”), our independent registered publicaccounting firm since April 5, 2018, during the years ended December 31, 2019 and 2018: Year Ended December 31, 2019 2018 (1) (in millions)Audit Fees (2) $1.1 $1.5Audit-Related Fees — —Tax Fees — —All Other Fees— —Total$1.1 $1.5________________________________(1)In connection with the Transactions, we appointed Grant Thornton as our independent registered public accounting firm on April 5, 2018, replacing KPMG LLP.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Partnership as of December 31, 2019 and2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with accountingprinciples 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 internalcontrol over financial reporting as of December 31, 2019, based on criteria established in the 2013 Internal Control-Integrated Framework issued by theCommittee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 18, 2020 expressed an unqualified opinionthereon.Change in accounting principleAs discussed in Note 2 to the consolidated financial statements, the Partnership has changed its method of accounting for leases due to the adoption of the newleasing standard. The Partnership adopted the new leasing standard by recognizing a cumulative catch-up adjustment to the opening balance sheet as of January 1,2019.Basis for opinionThese financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on the Partnership’s financialstatements 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 inaccordance 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 reasonableassurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures toassess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Suchprocedures included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our audits also included evaluating theaccounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believethat our audits provide a reasonable basis for our opinion.Critical audit matterThe critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to becommunicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especiallychallenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, takenas a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts ordisclosures to which it relates.Goodwill Impairment AssessmentIn evaluating whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the Partnership performed a qualitativeassessment of relevant events and circumstances. If, after assessing the totality of events and circumstances, it was deemed more likely than not that the fair valueof the reporting unit is less than its carrying amount, the Partnership estimated the fair value of the reporting unit by performing a quantitative goodwill impairmentassessment. As of October 1, 2019, the Partnership’s most recent assessment date, the Partnership concluded that it is not more likely than not that the fair value ofits reporting unit was less than its carrying amount. We have identified management’s assessment of qualitative factors for the annual goodwill impairmentassessment as a critical audit matter.The principal consideration for our determination that the assessment of qualitative factors for the annual goodwill impairment assessment is a critical audit matteris that there are significant judgements management made in assessing and weighting the relevant qualitative factors in determining whether it was more likelythan not that the fair value of its reporting unit was less than its carrying amount. Those factors include (i) macroeconomic conditions, (ii) industry and marketconsiderations, (iii) cost factors,F-2Table of Contents(iv) overall financial performance of the reporting unit, (v) other relevant entity-specific events, and (vi) consideration of whether there was a sustained decrease inthe price of Partnership units.Our audit procedures related to the assessment of qualitative factors for the annual goodwill impairment assessment included the following procedures, amongothers. We tested the effectiveness of controls relating to management’s review of the assessment of qualitative factors. In addition to testing the effectiveness ofcontrols, we also performed the following:•Reviewed the application of the relevant accounting guidance with respect to the qualitative factors considered by thePartnership.•Evaluated the qualitative factors assessed by management forreasonableness.•Compared the actual current results of the reporting unit to the Partnership’s historical and forecastedperformance./s/ GRANT THORNTON LLPWe have served as the Partnership’s auditor since 2017.Houston, TexasFebruary 18, 2020F-3Table of ContentsUSA COMPRESSION PARTNERS, LPConsolidated Balance

Partnership” and similar language when used in thepresent or future tense and for periods on and subsequent to April 2, 2018 (the “Transactions Date”) refer to USA Compression Partners, LP, collectively with itsconsolidated operating subsidiaries, including the USA Compression Predecessor. Unless the context otherwise requires or where otherwise indicated, the term“USA Compression Predecessor,” as well as the terms “our,” “we,” “us” and “its” when used in a historical context or in reference to periods prior to theTransactions Date, refer to CDM Resource Management LLC (“CDM Resource”) and CDM Environmental & Technical Services LLC (“CDM E&T”)collectively, which has been deemed to be the predecessor of the Partnership for financial reporting purposes.We are a Delaware limited partnership. Through our operating subsidiaries, we provide compression services under fixed-term contracts with customers in thenatural gas and crude oil industries, using natural gas compression packages that we design, engineer, own, operate and maintain. We primarily providecompression services in a number of shale plays throughout the United States, 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.” TheGeneral Partner has been wholly owned by Energy Transfer Operating, L.P. (“ETO”) since October 2018, when Energy Transfer Equity, L.P. (“ETE”) and EnergyTransfer Partners, L.P. (“ETP”) completed the merger of ETP with a wholly owned subsidiary of ETE in a unit-for-unit exchange (the “ETE Merger”). Followingthe closing of the ETE Merger, ETE changed its name to “Energy Transfer LP” (“ET LP”) and ETP changed its name to “Energy Transfer Operating, L.P.” Uponthe closing of the ETE Merger, ETE contributed to ETO 100% of the limited liability company interests in the General Partner. References herein to “ETO” referto ETP for periods prior to the ETE Merger and ETO following the ETE Merger, and references to “ET LP” refer to ETE for periods prior to the ETE Merger andET LP following the ETE Merger.The USA Compression Predecessor owned and operated a fleet of compressors used to provide natural gas compression services for customer specificsystems. The USA Compression Predecessor also owned and operated a fleet of equipment used to provide natural gas treating services, such as carbon dioxide andhydrogen sulfide removal, cooling, and dehydration. The USA Compression Predecessor had operations located in Texas, Oklahoma, Louisiana, Arkansas,Pennsylvania, New Mexico, Colorado, Ohio, and West Virginia.Certain of our operating subsidiaries are borrowers under a revolving credit facility and the Partnership is a guarantor of that revolving credit facility (see Note10). The accompanying consolidated financial statements include the accounts of the Partnership and its operating subsidiaries, all of which are wholly owned byus.Net loss attributable to partners is allocated to our common units and Class B Units using the two-class income allocation method. All intercompany balancesand 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 andother administrative services for us, such as accounting, corporate development, finance and legal. All of our employees, including our executive officers, areemployees of USAC Management. As of December 31, 2019, USAC Management had 879 full time employees. None of our employees are subject to collectivebargaining agreements.CDM AcquisitionOn the Transactions Date, we consummated the transactions contemplated by the Contribution Agreement dated January 15, 2018, pursuant to which, amongother things, we acquired all of the issued and outstanding membership interests of the USA Compression Predecessor from ETO (the “CDM Acquisition”) inexchange for aggregate consideration of approximately $1.7 billion, consisting of (i) 19,191,351 common units representing limited partner interests in us (the“common units”), (ii) 6,397,965 Class B units representing limited partner interests in us (“Class B Units”) and (iii) $1.2 billion in cash (including customaryclosing adjustments). On July 30, 2019, 6,397,965 Class B Units automatically converted into common units on a one-for-one basis, resulting in the issuance of6,397,965 common units to ETO. Following the conversion, there are no longer Class B Units outstanding.F-8Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsGeneral Partner Purchase AgreementOn the Transactions Date, and in connection with the closing of the CDM Acquisition, we consummated the transactions contemplated by the PurchaseAgreement dated January 15, 2018, by and among ET LP, Energy Transfer Partners, L.L.C., USA Compression Holdings, LLC (“USA Compression Holdings”)and, solely for certain purposes therein, R/C IV USACP Holdings, L.P. and ETO, pursuant to which, among other things, ET LP acquired from USA CompressionHoldings (i) all of the outstanding limited liability company interests in the General Partner and (ii) 12,466,912 common units for cash consideration paid by ETLP to USA Compression Holdings equal to $250.0 million (the “GP Purchase”). Upon the closing of the ETE Merger, ET LP contributed all of the interests in theGeneral Partner and the 12,466,912 common units to ETO.Equity Restructuring AgreementOn the Transactions Date, and in connection with the closing of the CDM Acquisition, we consummated the transactions contemplated by the EquityRestructuring Agreement dated January 15, 2018 (the “Equity Restructuring Agreement”), pursuant to which, among other things, the Partnership, the GeneralPartner and ET LP agreed to cancel the Partnership’s Incentive Distribution Rights (“IDRs”) and convert the General Partner’s interest into a non-economic generalpartner interest, in exchange for the Partnership’s issuance of 8,000,000 common units to the General Partner (the “Equity Restructuring”). In addition, at any timeafter one year following the Transactions Date, ET LP has the right to contribute (or cause any of its subsidiaries to contribute) to us all of the outstanding equityinterests in any of its subsidiaries that owns the general partner interest in us in exchange for $10.0 million (the “GP Contribution”); provided that the GPContribution will occur automatically if at any time following the Transactions Date (i) ET LP or one of its subsidiaries (including ETO) owns, directly orindirectly, the general partner interest in us and (ii) ET LP and its subsidiaries (including ETO) collectively own less than 12,500,000 of our common units.The CDM Acquisition, GP Purchase and Equity Restructuring are collectively referred to as the “Transactions.”(2)Basis of Presentation and Significant Accounting PoliciesBasis of PresentationThe PartnershipThe consolidated financial statements give effect to the business combination and the Transactions discussed above under the acquisition method ofaccounting, and the business combination has been accounted for in accordance with the applicable reverse merger accounting guidance. ET LP acquired acontrolling financial interest in us through the acquisition of the General Partner. As a result, the USA Compression Predecessor is deemed to be the accountingacquirer of the Partnership because its ultimate parent company obtained control of the Partnership through its control of the General Partner. Consequently, theUSA Compression Predecessor is deemed to be the predecessor of the Partnership for financial reporting purposes, and the historical financial statements of thePartnership now reflect the USA Compression Predecessor for all periods prior to the closing of the Transactions. The closing of the Transactions occurred on theTransactions Date.The USA Compression Predecessor’s assets and liabilities retained their historical carrying values. Additionally, the Partnership’s assets acquired andliabilities assumed by the USA Compression Predecessor in the business combination have been recorded at their fair values measured as of the Transactions Date.The excess of the assumed purchase price of the Partnership over the estimated fair values of the Partnership’s net assets acquired has been recorded as goodwill.The assumed purchase price and fair value of the Partnership has been determined using acceptable fair value methods. Additionally, because the USACompression Predecessor is reflected at ET LP’s historical cost, the difference between the $1.7 billion in consideration paid by the Partnership and ET LP’shistorical carrying values (net book value) at the Transactions Date has been recorded as a decrease to partners’ capital in the amount of $36.1 million.Our accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ofAmerica (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). As noted above, the historicalconsolidated financial statements of the Partnership now reflect the historical consolidated financial statements of the USA Compression Predecessor inaccordance with the applicable accounting and financial reporting guidance. Therefore, the historical consolidated financial statements are comprised of thebalance sheet and statement of operations of the USA Compression Predecessor as of and for periods prior to the Transactions Date. The historical consolidatedfinancial statements are also comprised of the consolidated balance sheet and statement of operations of the Partnership, which includes the USA CompressionPredecessor, as of and for all periods subsequent to the Transactions Date. The presentation of certain line items in historical periods have been conformed to thePartnership’s current year presentation for comparability.F-9Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsUSA Compression PredecessorETO allocated various corporate overhead expenses to the USA Compression Predecessor based on a percentage of assets, net income (loss), or adjustedearnings before interest, taxes, depreciation and amortization (“EBITDA”). These allocations are not necessarily indicative of the cost that the USA CompressionPredecessor would have incurred had it operated as an independent standalone entity. The USA Compression Predecessor also historically relied upon ETO forfunding operating and capital expenditures as necessary. As a result, the historical financial statements of the USA Compression Predecessor may not fully reflector be necessarily indicative of what the USA Compression Predecessor’s balance sheet, results of operations and cash flows would have been or will be in thefuture. Certain expenses incurred by ETO are only indirectly attributable to the USA Compression Predecessor. As a result, certain assumptions and estimates aremade in order to allocate a reasonable share of such expenses to the USA Compression Predecessor, so that the accompanying financial statements reflectsubstantially all costs of doing business. The allocations and related estimates and assumptions are described more fully in Note 14.Certain amounts of the USA Compression Predecessor’s revenues are derived from related party transactions, as described more fully in Note 14. Significant Accounting PoliciesCash and Cash EquivalentsCash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of90 days or less to be cash equivalents. Trade Accounts Receivable and Allowance for Doubtful AccountsTrade accounts receivable are recorded at the invoiced amount and do not bear interest. Our determination of the allowance for doubtful accounts requires usto make estimates and judgments regarding our customers’ ability to pay amounts due. We continuously evaluate the financial strength of our customers based onpayment history, the overall business climate in which our customers operate and specific identification of customer bad debt and make adjustments to theallowance as necessary. Our evaluation of our customers’ financial strength is based on the aging of their respective receivables balance, customer correspondence,financial information and third-party credit ratings. Our evaluation of the business climate in which our customers operate is based on a review of various publicly-available materials regarding our customers’ industries, including the solvency of various companies in the industry.The USA Compression Predecessor determined its allowance for doubtful accounts based upon historical write-off experience and specific identification ofunrecoverable amounts. InventoriesInventories consist of serialized and non-serialized parts used primarily in the repair of compression units. All inventories are stated at the lower of cost or netrealizable value. Serialized parts inventories are recorded using the specific identification method, while non-serialized parts inventories are recorded using theweighted average cost method. Purchases of these assets are considered operating activities in the Consolidated Statements of Cash Flows. Property and EquipmentProperty 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 improvementsthat increase the value or extend the life of compression equipment are capitalized and depreciated over three to five years. Ordinary maintenance and repairs arecharged 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 anyassociated gains or losses are recorded on our statements of operations in the period of sale or disposition.F-10Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsCapitalized interest is calculated by multiplying the Partnership’s 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 $0.5 million and $0.3 million for the years ended December 31,2019 and 2018, respectively. The USA Compression Predecessor had no capitalized interest for the year ended December 31, 2017, as it did not hold any debtduring the period.Impairments of Long-Lived AssetsLong-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 theoperating fleet. The most common circumstance requiring compression units to be tested for impairment is when idle units do not meet the performancecharacteristics 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 eventualdisposition of the asset. If the carrying value exceeds the sum of the undiscounted cash flows associated with the operating fleet, an impairment loss equal to theamount 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 theabsence of quoted market prices, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleetunits 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.Refer to Note 6 for more detailed information about impairment charges during the years ended December 31, 2019, 2018 and 2017. Identifiable Intangible AssetsIdentifiable intangible assets are recorded at cost and amortized using the straight-line method over their estimated useful lives, which is the period over whichthe assets are expected to contribute directly or indirectly to our future cash flows. The estimated useful lives 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 berecoverable. We did not record any impairment of identifiable intangible assets for the years ended December 31, 2019, 2018 or 2017.GoodwillGoodwill 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 carryingvalue of goodwill may not be recovered. The Partnership did not record any goodwill impairment during the years ended December 31, 2019 and 2018. The USA Compression Predecessor recorded$223.0 million of goodwill impairment for the year ended December 31, 2017. Refer to the Goodwill section in Note 6 for more information about the goodwillimpairment assessment performed during the years ended December 31, 2019, 2018 and 2017.Predecessor Parent Company Net InvestmentThe USA Compression Predecessor participated in a centralized cash management function managed by ETO. Balances payable to or due from ETOgenerated under this arrangement are reflected in Predecessor parent company net investment.ETO’s net investment in the operations of the USA Compression Predecessor is presented as Predecessor parent company net investment within theconsolidated balance sheets. Predecessor parent company net investment represents the accumulated net earnings of the operations of the USA CompressionPredecessor and accumulated net contributions from ETO. Net contributions for the period January 1, 2018 to April 1, 2018 were primarily comprised ofintercompany operations and expense, cash clearing and other financing activities, and general and administrative cost allocations to the USA CompressionPredecessor. F-11Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsIncome TaxesWe 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 incometaxes based upon their distributive share of the Partnership’s income, gain, loss, or deduction. Texas imposes an entity-level income tax on partnerships that isbased on Texas sourced taxable margin. The Partnership has included in the consolidated financial statements a provision for Texas Margin Tax. Refer to Note 9for more detailed information about the Texas Margin Tax for the years ended December 31, 2019, 2018 and 2017.Pass Through TaxesSales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis.Fair Value MeasurementsAccounting standards on fair value measurements establish a framework for measuring fair value and stipulate disclosures about fair value measurements. Thestandards apply to recurring and non-recurring financial and non-financial assets and liabilities that require or permit fair value measurements. Among the requireddisclosures 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, 2019, our financial instruments consisted primarily of cash and cash equivalents, trade accounts receivable, trade accounts payable andlong-term debt. The book values of cash and cash equivalents, trade accounts receivable, and trade accounts payable are representative of fair value due to theirshort-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 (collectively, the “Senior Notes”), both defined in Note 10, were estimated using quoted pricesin inactive markets and are considered Level 2 measurements.The following table summarizes the aggregate principal amount and fair value of our Senior Notes (in thousands): December 31, 2019 2018Senior Notes 2026, aggregate principal$725,000 $725,000Fair value of Senior Notes 2026764,875 696,000Senior Notes 2027, aggregate principal750,000 —Fair value of Senior Notes 2027785,625 —As part of the impairment analysis of goodwill as of December 31, 2017, the fair value of the USA Compression Predecessor’s goodwill was re-measuredusing Level 3 inputs. Refer to the Goodwill section in Note 6 for more information about this valuation as of December 31, 2017.Use of EstimatesThe preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amountsreported in these consolidated financial statements and the accompanying results. Although these estimates are based on management’s available knowledge ofcurrent and expected future events, actual results could differ from these estimates.F-12Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsOperating SegmentWe operate in a single business segment, the compression services business.Adoption of Lease Accounting StandardIn February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842),which has amended the FASB Accounting Standards Codification (“ASC”) and introduced ASC Topic 842, Leases (“ASC Topic 842”). On January 1, 2019, weadopted ASC Topic 842, which is effective for interim and annual reporting periods beginning on or after December 15, 2018. ASC Topic 842 requires entities torecognize 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 notrecorded on the balance sheet in accordance with the prior standard.To adopt ASC Topic 842, we recognized a cumulative catch-up adjustment to the opening balance sheet presented January 1, 2019 related to certain leasesthat existed as of that date. As permitted, we have not retrospectively modified our consolidated financial statements for comparative purposes. The adoption of thestandard had an impact on our consolidated balance sheet, but did not have an impact on our consolidated statements of operations or cash flows. As a result ofadoption, we have recorded additional net right-of-use (“ROU”) lease assets and lease liabilities of approximately $3.5 million and $3.7 million, respectively, as ofJanuary 1, 2019. In addition, we have updated our business processes, systems and internal controls to support the on-going reporting requirements under the newstandard.To adopt ASC Topic 842, we elected the package of practical expedients permitted under the transition guidance within the standard. The expedient packageallowed us not to reassess whether existing contracts contained a lease, the lease classification of existing leases and initial direct cost for existing leases. Inaddition to the package of practical expedients, we have elected not to capitalize amounts pertaining to leases with terms less than twelve months, to use theportfolio approach to determine discount rates, not to separate non-lease components from lease components and not to apply the use of hindsight to the activelease population.Cumulative-effect adjustments made to the opening balance sheet at January 1, 2019 were as follows (in thousands):Balance Sheet Line Item Balance at December 31,2018, as previouslyreported Adjustments due toASC Topic 842(Leases) Balance at January 1,2019Other assets $— $3,502 $3,502Accrued liabilities — (2,015) (2,015)Other liabilities — (1,706) (1,706)Additional disclosures related to lease accounting are included in Note 8.(3)AcquisitionsThe USA Compression Predecessor is deemed to be the accounting acquirer of the Partnership in the business combination because its ultimate parentcompany obtained control of the Partnership through its control of the General Partner. Consequently, the USA Compression Predecessor’s assets and liabilitiesretained their historical carrying values. The Partnership’s assets acquired and liabilities assumed by the USA Compression Predecessor have been recorded attheir fair values measured as of the Transactions Date. The excess of the assumed purchase price of the Partnership over the estimated fair values of thePartnership’s net assets acquired has been recorded as goodwill. The assumed purchase price and fair value of the Partnership was determined using a combinationof an income and cost valuation methodology, the fair value of the Partnership’s common units as of the Transactions Date and the consideration paid by ET LPfor the General Partner and IDRs. The valuation and purchase price allocation is considered final.The property and equipment of the USA Compression Predecessor is reflected at historical carrying value, which is less than the consideration paid for thebusiness. The excess of the consideration paid over the historical carrying value was $36.1 million and is reflected as a decrease to partners’ capital.F-13Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsThe Partnership incurred $21.7 million in transaction-related expenses prior to the Transactions Date, which were recognized by the Partnership when incurredin the periods prior to the Transactions Date, and therefore are not included within the results of operations presented within the consolidated financial statementsfor the year ended December 31, 2018.For the period from April 2, 2018 to December 31, 2018, we recognized $269.2 million in revenues and $23.1 million in net income attributable to thePartnership’s historical assets.The following table summarizes the assumed purchase price and fair value and the allocation to the assets acquired and liabilities assumed (in thousands): Assumed purchase price allocation to USA Compression Partners, LP: Current assets$786,258Fixed assets1,331,850Other long-term assets15,018Customer relationships221,500Total identifiable assets acquired2,354,626Current liabilities(110,465)Long-term debt(1,526,865)Other long-term liabilities(1,538)Total liabilities assumed(1,638,868)Net identifiable assets acquired715,758Goodwill (1)365,983Net assets acquired$1,081,741 April 2, 2018 Transactions: Cash assumed in the CDM Acquisition$(710,506)Issuance of Preferred Units(465,121)Issuance of Class B Units for the CDM Acquisition(86,125)Issuance of Warrants(13,979)Issuance of common units for the Equity Restructuring(135,440)Issuance of common units for the CDM Acquisition(324,910)Purchase price adjustment for USA Compression Partners, LP$(654,340)________________________________(1)Goodwill recognized from the business combination primarily relates to the value attributed to additional growth opportunities, synergies and operating leverage within thePartnership’s areas of operation. The valuation of goodwill recognized from the business combination is final.Transition Services AgreementIn connection with the closing of the Transactions, we entered into an agreement with the USA Compression Predecessor and ETO pursuant to which ETOand its affiliates provided certain services to us with respect to the business and operations of the USA Compression Predecessor’s existing assets, includinginformation technology, accounting and emissions testing services, for a period of three months following the closing of the Transactions. Expenses associated withthe transition services agreement were $0.7 million for the year ended December 31, 2018.Unaudited Pro Forma Financial InformationThe following unaudited pro forma condensed financial information for the years ended December 31, 2018 and 2017 gives effect to the Transactions as ifthey had occurred on January 1, 2017. The unaudited pro forma condensed financial information has been included for comparative purposes only and is notnecessarily indicative of the results that might have occurred had the Transactions taken place on the dates indicated and is not intended to be a projection of futureevents. The pro forma adjustmentsF-14Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementsfor the periods presented consist of (i) adjustments to combine the USA Compression Predecessor’s and the Partnership’s historical results of operations for theperiods, (ii) adjustments to interest expense to include interest expense for additional revolving credit facility borrowings and include the interest expenseassociated with our Senior Notes 2026 (see Note 10), (iii) adjustments to depreciation and amortization expense attributable to adjustments recorded as a result ofthe purchase price allocation to the Partnership’s assets and liabilities and (iv) adjustments to net loss attributable to common units and Class B Units attributable todistributions on the Partnership’s Series A Preferred Units (the “Preferred Units”).The following table presents the unaudited pro forma revenues, net loss and basic and diluted net loss per unit information for each period (in thousands,except per unit amounts): Year Ended December 31, 2018 2017Total revenues$662,091 $556,893Net loss(44,894) (344,995)Net loss attributable to common and Class B unitholders’ interests(93,644) (393,745)Basic and diluted net loss per common unit and Class B Unit(0.98) (4.14)The pro forma net loss for the year ended December 31, 2018 includes expenses that were a direct result of the Transactions, including $1.0 million inemployee severance charges attributable to employees not retained by the Partnership subsequent to the Transactions and $21.7 million in transaction expenses,including advisory, audit and legal fees. These expenses were recognized by the Partnership as they were incurred during the period from January 1, 2018 to April1, 2018, but because the USA Compression Predecessor’s historical condensed consolidated financial statements are now reflected for that period, the condensedconsolidated financial statements presented in accordance with GAAP for the year ended December 31, 2018 do not reflect such expenses incurred as a directresult of the Transactions.(4)Trade Accounts ReceivableThe allowance for doubtful accounts, which was $2.5 million and $1.7 million as of December 31, 2019 and 2018, respectively, is our best estimate of theamount of probable credit losses included in our existing accounts receivable.During the year ended December 31, 2019, we recognized bad debt expense of $1.1 million and wrote-off $0.3 million of receivables on accounts previouslyreserved, resulting in an $0.8 million increase in our allowance for doubtful accounts. During the year ended December 31, 2018, we increased our allowance fordoubtful accounts by $0.9 million, due primarily to estimated uncollectible amounts from customers of the USA Compression Predecessor.The USA Compression Predecessor reduced its allowance for doubtful accounts by $4.1 million during the year ended December 31, 2017 due to write-offs ofreceivables and collections on accounts previously reserved. Due to the decrease in the allowance for doubtful accounts during 2017, the USA CompressionPredecessor recognized a reduction of bad debt expense of $1.8 million for the year ended December 31, 2017.(5)InventoriesComponents of inventories were as follows (in thousands): December 31, 2019 2018Serialized parts$43,890 $45,568Non-serialized parts48,033 43,439Total inventories$91,923 $89,007F-15Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statements(6)Property and Equipment, Identifiable Intangible Assets andGoodwillProperty and EquipmentProperty and equipment consisted of the following (in thousands): December 31, 2019 2018Compression and treating equipment$3,384,985 $3,239,831Computer equipment54,940 54,806Automobiles and vehicles33,544 32,490Buildings8,639 9,314Leasehold improvements7,395 5,377Furniture and fixtures1,543 1,129Land77 77Total property and equipment, gross3,491,123 3,343,024Less: accumulated depreciation and amortization(1,008,180) (821,536)Total property and equipment, net$2,482,943 $2,521,488Depreciation is calculated using the straight-line method over the estimated useful lives of the assets as follows:Compression equipment, acquired new25 yearsCompression equipment, acquired used5 - 25 yearsFurniture and fixtures3 - 10 yearsVehicles and computer equipment1 - 10 yearsBuildings5 yearsLeasehold improvements5 yearsDepreciation expense on property and equipment was $202.0 million, $186.5 million and $146.0 million for the years ended December 31, 2019, 2018 and2017, respectively.The Partnership implemented a change in the estimated useful lives of the USA Compression Predecessor’s property and equipment to conform to thePartnership’s historical asset lives, which is accounted for as a change in accounting estimate beginning on the Transactions Date on a prospective basis. Thischange resulted in a $33.8 million increase to both operating income and net income for the year ended December 31, 2018, and a $0.42 increase to both basic anddiluted earnings per common unit and Class B Unit for year ended December 31, 2018.As of December 31, 2019 and 2018, there was $11.4 million and $7.9 million, respectively, of property and equipment purchases in accounts payable andaccrued liabilities.During the years ended December 31, 2019 and 2018, there were net losses on the disposition of assets of $0.9 million and $13.0 million, respectively. For theyear ended December 31, 2018, these net losses were primarily related to disposals of various property and equipment by the USA Compression Predecessor. During the year ended December 31, 2017, the USA Compression Predecessor recognized a $0.4 million net gain on disposition of assets.For the years ended December 31, 2019 and 2018, we evaluated the future deployment of our idle fleet under then-current market conditions anddetermined to retire and re-utilize key components of 33 and 103 compressor units, respectively, or approximately 11,000 and 33,000 horsepower, respectively,that were previously used to provide services in our business. As a result, we recorded $5.9 million and $8.7 million in impairment of compression equipment forthe years ended December 31, 2019 and 2018, respectively. The primary causes for this impairment were: (i) units were not considered marketable in theforeseeable future, (ii) units were subject to excessive maintenance costs or (iii) units were unlikely to be accepted by customers due to certainF-16Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementsperformance characteristics of the unit, such as the inability to meet then-current quoting criteria without excessive retrofitting costs. These compression unitswere written down to their respective estimated salvage values, if any.

The expectedamortization of the intangible assets for each of the five succeeding years is $29.4 million.GoodwillAs of December 31, 2019 and 2018, the Partnership had $619.4 million of goodwill. There were no changes to the carrying value of goodwill during the yearended December 31, 2019.As of October 1, 2019 and 2018, we performed a qualitative assessment of relevant events and circumstances potentially indicating the likelihood of goodwillimpairment. The qualitative assessment included weighting such factors as (i) macroeconomic conditions, (ii) industry and market considerations, (iii) costfactors, (iv) overall financial performance of the reporting unit, (v) other relevant entity-specific events, and (vi) consideration of whether there was a sustaineddecrease in the price of our units. Upon completion of our qualitative assessment, we concluded that it is not more likely than not that the fair value of our singlereporting unit was less than its carrying value and that our goodwill was not impaired for the years ended December 31, 2019 and 2018.For the year ended December 31, 2017 and in accordance with its early adoption of ASU 2017-04, the USA Compression Predecessor performed aquantitative assessment for its annual goodwill impairment test and determined its fair value using a weighted combination of the discounted cash flow method andthe guideline company method. Determining the fair value of a reporting unit requires judgment and the use of significant estimates and assumptions. Suchestimates and assumptions include revenue growth rates, operating margins, weighted average costs of capital and future market conditions, among others. TheUSA Compression Predecessor believed the estimates and assumptions used in the impairment assessment were reasonable and based on available marketinformation, but variations in any of the assumptions could have resulted in materially different calculations of fair value and determinations of whether or not animpairment is indicated. Under the discounted cash flow method, the USA Compression Predecessor determined fair value based on estimated future cash flowsincluding estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflects the overall level of inherent risk of thecompany. Cash flow projections were derived from one year budgeted amounts and five year operating forecasts plus an estimate of later period cash flows, all ofwhich were developed by management. Subsequent period cash flows were developed using growth rates that management believed were reasonably likely tooccur. Under the guideline company method, the USA Compression Predecessor determined its estimated fair value by applying valuation multiples of comparablepublicly-traded companies to theF-17Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementsprojected EBITDA of the company and then averaging that estimate with similar historical calculations using a three-year average. In addition, the USACompression Predecessor estimated a reasonable control premium representing the incremental value that accrues to the predecessor’s majority owner from theopportunity to dictate the strategic and operational actions of the business. Additionally, the USA Compression Predecessor considered the presence andprobability of subsequent events on market transactions in estimating the fair value of the company, such as the Transactions discussed in Note 1.Based on the completion of the annual goodwill impairment testing as described above, the USA Compression Predecessor recorded a $223.0 millionimpairment equal to the excess of the carrying value over fair value for the year ended December 31, 2017.(7)Other CurrentLiabilitiesComponents of other current liabilities included the following (in thousands): December 31, 2019 2018Accrued sales tax contingencies (1)$48,883 $44,923Accrued interest expense31,210 16,355Accrued payroll and benefits10,687 10,681Accrued capital expenditures11,357 7,949________________________________(1)Refer to Note 17 for further detailed information on the accrued sales tax contingencies.(8)Lease AccountingLessee AccountingWe maintain both finance leases and operating leases, primarily related to office space, warehouse facilities and certain corporate equipment. Our leases haveremaining lease terms of up to 10 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 assets, accrued liabilities and operating leaseliabilities in our consolidated balance sheets. Finance leases are included in property and equipment, accrued liabilities and other liabilities in our consolidatedbalance 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 arisingfrom 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. Asmost of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available on the commencement date indetermining the present value of lease payments. ROU lease assets also include any lease payments made and exclude lease incentives. Our lease terms mayinclude 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 astraight-line basis over the lease term. Variable costs such as our proportionate share of actual costs for utilities, common area maintenance, property taxes andinsurance 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 noROU 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.F-18Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsSupplemental balance sheet information related to leases consisted of the following (in thousands): December 31, 2019 2018Operating leases: Lease right-of-use assets$18,317 $—Accrued liabilities(2,451) —Operating lease liabilities(17,343) —Finance leases: Property and equipment, gross$7,268 $7,683Accumulated depreciation(5,845) (4,882)Property and equipment, net1,423 2,801Accrued liabilities(774) (1,085)Other liabilities(1,550) (2,114)Components of lease expense consisted of the following (in thousands): Income Statement Line Item Year Ended December31, 2019Operating lease costs: Operating lease costCost of operations, exclusive of depreciation and amortization $1,796Operating lease costSelling, general and administrative 1,165Total operating lease costs 2,961Finance lease costs: Amortization of lease assetsDepreciation and amortization 1,638Short-term lease costs: Short-term lease costCost of operations, exclusive of depreciation and amortization 309Short-term lease costSelling, general and administrative 34Total short-term lease costs 343Variable lease costs: Variable lease costCost of operations, exclusive of depreciation and amortization 226Variable lease costSelling, general and administrative 1,130Total variable lease costs 1,356Total lease costs $6,298The weighted average remaining lease terms and weighted average discount rates were as follows: December 31, 2019Weighted average remaining lease term: Operating leases8 yearsFinance leases4 yearsWeighted average discount rate: Operating leases4.9%Finance leases2.6%F-19Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsSupplemental cash flow information related to leases consisted of the following (in thousands): Year Ended December31, 2019Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases$(3,001)Operating cash flows from finance leases(788)Financing cash flows from finance leases(1,035)ROU assets obtained in exchange for lease obligations: Operating leases$17,367Finance leases259Maturities of lease liabilities as of December 31, 2019 consisted of the following (in thousands): Operating Leases Finance Leases Total2020$3,358 $814 $4,17220213,046 567 3,61320222,849 398 3,24720232,738 369 3,10720242,627 284 2,911Thereafter9,625 — 9,625Total lease payments24,243 2,432 26,675Less: present value discount(4,449) (108) (4,557)Present value of lease liabilities$19,794 $2,324 $22,118As of December 31, 2019, we have entered into two operating leases that have not yet commenced with an estimated present value of $7.1 million. Theseoperating leases will both commence in the first quarter of 2020 and have terms of two years and ten years.Lessor AccountingWe granted a bargain purchase option to a customer with respect to certain compressor packages leased to the customer. The bargain purchase option providesthe 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 in 2021.We accounted for this option as a sales type lease resulting in a current installment receivable included in other accounts receivable of $4.0 million and $3.7million, and a long-term installment receivable included in other assets of $2.9 million and $6.9 million as of December 31, 2019 and December 31, 2018,respectively.Revenue and interest income related to the lease is recognized over the lease term. We recognize maintenance revenue within contract operations revenue andinterest income within interest expense, net. Maintenance revenue recognized for the years ended December 31, 2019 and 2018 was $1.3 million and $1.0 million,respectively. Interest income recognized for the years ended December 31, 2019 and 2018 was $0.7 million and $0.7 million, respectively. The USA CompressionPredecessor had no lease revenue, maintenance revenue or interest income related to leases for the year ended December 31, 2017.F-20Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsLease payments expected to be received subsequent to December 31, 2019 are as follows (in thousands): Receivables2020$5,67320213,356Total installment receivables9,029Less: present value discount(2,105)Present value of installment receivables$6,924ASC Topic 842 provides lessors with a practical expedient to not separate non-lease components from the associated lease components and, instead, toaccount for those components as a single component if the non-lease components otherwise would be accounted for under ASC Topic 606 Revenue from Contractswith Customers (“ASC Topic 606”) and certain conditions are met. Our contract operations services agreements meet these conditions and we consider thepredominant component to be the non-lease components, resulting in the ongoing recognition of revenue following ASC Topic 606 guidance.(9)Income Tax Expense(Benefit)We, including the USA Compression Predecessor, are subject to the Texas Margin Tax, which applies a tax to our gross margin. We do not conduct businessin 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 of0.75% 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 federalincome 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 (benefit) are as follows (in thousands): Year Ended December 31, 2019 2018 2017Current tax expense$810 $189 $42Deferred tax expense (benefit)1,376 (2,663) 1,801Total income tax expense (benefit)$2,186 $(2,474) $1,843Deferred income tax balances are the direct effect of temporary differences between the financial statement carrying amounts and the tax basis of assets andliabilities at the enacted tax rates expected to be in effect when the taxes are actually paid or recovered.

As of December 31, 2019, we had no material unrecognized taxbenefits (as defined in ASC Topic 740). We do not expect to incur interest charges or penalties related to our tax positions, but if such charges or penalties areincurred, our policy is to account for interest charges as Interest expense, net and penalties as Income tax expense in the Consolidated Statements of Operations.The Bipartisan Budget Act of 2015 provides that any tax adjustments (including any applicable penalties and interest) resulting from partnership audits willgenerally be determined at the partnership level for tax years beginning after December 31, 2017. To the extent possible under these rules, our general partner mayelect to either pay the taxes (including any applicable penalties andF-21Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementsinterest) directly to the Internal Revenue Service or, if we are eligible, issue a revised information statement to each unitholder and former unitholder with respectto 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 filedfor partnership taxable years beginning after the date of the enactment, November 2, 2015.

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 orinvestments;•incur additional indebtedness or guarantee other indebtedness;•enter into transactions with affiliates;•merge or consolidate;•sell our assets;or•make certainacquisitions.The revolving credit facility 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;and•a maximum funded debt to EBITDA ratio, determined as of the last day of each fiscal quarter, for the annualized trailing three months of (i) 5.5 to 1.0through the end of the fiscal quarter ending December 31, 2019 and (ii) 5.0 to 1.0 thereafter,F-22Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementsin each case subject to a provision for increases to such thresholds by 0.5 in connection with certain future acquisitions for the six consecutive monthperiod following the period in which any such acquisition occurs.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 andremedies.In connection with entering into the amended Credit Agreement, we paid certain upfront fees and arrangement fees to the arrangers, syndication agents andsenior managing agents of the Credit Agreement in the amount of $14.3 million during the year ended December 31, 2018. These fees were capitalized to loancosts and will be amortized through April 2023. Amounts borrowed and repaid under the Credit Agreement may be re-borrowed.As of December 31, 2019, we were in compliance with all of our covenants under the Credit Agreement. As of December 31, 2019, we had outstanding borrowings under the Credit Agreement of $402.7 million, $1.2 billion of borrowing base availability and,subject to compliance with the applicable financial covenants, available borrowing capacity of $484.4 million. The borrowing base consists of eligible accountsreceivable, inventory and compression units. The largest component, representing 95% of the borrowing base as of December 31, 2019, was eligible compressionunits. Eligible compression units consist of compressor packages that are leased, rented or under service contracts to customers and carried in the financialstatements as fixed assets. Our weighted-average interest rate in effect for all borrowings under the Credit Agreement as of December 31, 2019 was 4.31%, with aweighted-average interest rate of 4.84% for the year ended December 31, 2019. There were no LCs issued as of December 31, 2019. We pay a commitment fee of0.375% on the unused portion of the revolving credit facility.The Credit Agreement matures in April 2023 and we expect to maintain it for the term. The Credit Agreement is a “revolving credit facility” that includes alock box arrangement, whereby remittances from customers are forwarded to a bank account controlled by the administrative agent and are applied to reduceborrowings under the facility. Senior Notes 2027On March 7, 2019, the Partnership and Finance Corp co-issued $750.0 million aggregate principal amount of senior notes due on September 1, 2027 (the“Senior Notes 2027”).

We issued 500,000 Preferred Units with a face value of $1,000 per Preferred Unit and issued two tranches of Warrants to the PreferredUnitholders, which included Warrants to purchase 5,000,000 common units with a strike price of $17.03 per unit and 10,000,000 common units with a strike priceof $19.59 per unit. The Warrants may be exercised by the holders thereof at any time beginning April 2, 2019 and before April 2, 2028. 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 uponconversion 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 receivecumulative quarterly cash distributions equal to $24.375 per Preferred Unit. As of December 31, 2019 and 2018, 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 perPreferred UnitAugust 10, 2018 (1) $24.107November 9, 2018 24.375February 8, 2019 24.375May 10, 2019 24.375August 9, 2019 24.375November 8, 2019 24.375(1)Pro-rated initial distributionAnnounced Quarterly DistributionOn January 16, 2020, we declared a cash distribution of $24.375 per unit on our Preferred Units. The distribution was paid on February 7, 2020 to unitholdersof record as of the close of business on January 27, 2020.Redemption and Conversion FeaturesThe Preferred Units are convertible, at the option of the Preferred Unitholders, into common units in accordance with the terms of the Partnership Agreementas follows: one third on or after April 2, 2021, two thirds on or after April 2, 2022, and the remainder on or after April 2, 2023. The conversion rate for thePreferred Units shall be the quotient of (a) the sum of (i) $1,000, plus (ii) any unpaid cash distributions on the applicable Preferred Unit, divided by (b) $20.0115for each Preferred Unit. The Preferred Unitholders are entitled to vote on an as-converted basis with the common unitholders and (as proportionately adjusted forunit splits, unit distributions and similar transactions) will have certain other class voting rights with respect to any amendment to the Partnership Agreement thatwould adversely affect any rights, preferences or privileges of the Preferred Units. In addition, upon certain events involving a change of control the PreferredUnitholders may elect, among other potential elections, to convert their Preferred Units to common units at the then change of control conversion rate.On or after April 2, 2023, we have the option to redeem all or any portion of the Preferred Units then outstanding. On or after April 2, 2028, the PreferredUnitholders have the right to require us to redeem all or a portion of the Preferred Units then outstanding, the purchase price for which we may elect to pay up to50% in common units, subject to certain additional limits. The Preferred Units are presented as temporary equity in the mezzanine section of the consolidatedbalance sheets because the redemption provisions on or after April 2, 2028 are outside the Partnership’s control.The Preferred Units were recorded at their issuance date fair value, net of issuance cost. Net income allocations increase the carrying value and declareddistributions decrease the carrying value of the Preferred Units. As the Preferred Units are not currently redeemable and it is not probable that they will becomeredeemable, adjustment to the initial carrying value is not necessary and would only be required if it becomes probable that the Preferred Units would becomeredeemable.F-26Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsChanges in the Preferred Units balance are summarized below (in thousands): Preferred UnitsBalance at December 31, 2017$—Issuance of Preferred Units on April 2, 2018, net465,121Net income allocated to Preferred Units36,430Cash distributions on Preferred Units(24,242)Balance at December 31, 2018477,309Net income allocated to Preferred Units48,750Cash distributions on Preferred Units(48,750)Balance at December 31, 2019$477,309The Warrants are presented within the equity section of the Consolidated Balance Sheets in accordance with GAAP as they are indexed to the Partnership’sown stock and require physical settlement or net share settlement.

Distribution Reinvestment PlanDuring the years ended December 31, 2019 and 2018, distributions of $1.0 million and $0.6 million, respectively, were reinvested under the DistributionReinvestment Plan (the “DRIP”) resulting in the issuance of 60,584 and 39,280 common units, respectively.Earnings Per UnitThe computations of earnings per unit are based on the weighted average number of participating securities outstanding during the period. Basic earnings perunit is determined by dividing net loss allocated to participating securities after deducting the amount distributed on Preferred Units, by the weighted averagenumber of participating securities outstanding during the period. Net loss attributable to unitholders is allocated to participating securities based on their respectiveshares of the distributed and undistributed earnings for the period. To the extent cash distributions exceed net loss attributable to unitholders for the period, theexcess distributions are allocated to all participating securities outstanding based on their respective ownership percentages. Diluted earnings per unit are computedusing the treasury stock method, which considers the potential issuance of limited partner units associated with our long-term incentive plan and warrants. Theclasses of participating securities include common units, Class B Units prior to July 30, 2019, and certain equity-based compensation awards. Unvested phantomunits and unexercised warrants are not included in basic earnings per unit, as they are not considered to be participating securities, but are included in thecalculation 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, 2019 and 2018, approximately 290,000 and 208,000 incremental unvested phantom units, respectively, were excluded fromthe calculation of diluted earnings per unit because the impact was anti-dilutive. Our outstandingF-28Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementswarrants are not applicable to the computation as they are not considered “in the money” for the years ended December 31, 2019 or 2018. Earnings per unit is notapplicable to the USA Compression Predecessor for the year ended December 31, 2017 as the USA Compression Predecessor had no outstanding common unitsprior to the Transactions.(13)RevenueRecognitionRevenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services orgoods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Sales taxes incurred onbehalf of, and passed through to, customers are excluded from revenue. Incidental items, if any, that are immaterial in the context of the contract are recognized asexpense.Adoption of ASC Topic 606, “Revenue from Contracts with Customers”On January 1, 2018, we adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC Topic 606”) using the modified retrospective methodapplied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASCTopic 606, while 2017 amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC Topic 605.We identified no material impact on our historical revenues upon initial application of ASC Topic 606, and as such have not recognized any cumulative catch-up effect to the opening balance of our partners’ capital as of January 1, 2018. Additionally, the application of ASC Topic 606 has no material impact on anycurrent financial statement line items.The following table disaggregates our revenue by type of service (in thousands): Year Ended December 31, 2019 2018 2017 (1)Contract operations revenue$681,472 $563,416 $266,130Retail parts and services revenue16,893 20,936 10,541Total revenues$698,365 $584,352 $276,671_______________________________(1)As noted above, 2017 amounts have not been adjusted under the modified retrospective method of ASC Topic 606.

Contract operations revenueRevenue from contracted compression, station, gas treating and maintenance services is recognized ratably under our fixed-fee contracts over the term of thecontract as services are provided to our customers. Initial contract terms typically range from six months to five years, however we usually continue to providecompression services at a specific location beyond the initial contract term, either through contract renewal or on a month-to-month or longer basis. We primarilyenter into fixed-fee contracts whereby our customers are required to pay our monthly fee even during periods of limited or disrupted throughput. Services aregenerally billed monthly, one month in advance of the commencement of the service month, except for certain customers who areF-29Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementsbilled 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 asdeferred revenue until earned, at which time they are recognized as revenue. The amount of consideration we receive and revenue we recognize is based upon thefixed 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 obligationbased on its relative standalone service fee. We generally determine standalone service fees based on the service fees charged to customers or use expected costplus margin.The majority of our service performance obligations are satisfied over time as services are rendered at selected customer locations on a monthly basis andbased upon specific performance criteria identified in the applicable contract. The monthly service for each location is substantially the same service month tomonth 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 andconsumes the benefits provided by our service. If variable consideration exists, it is allocated to the distinct monthly service within the series to which such variableconsideration relates. We have elected to apply the invoicing practical expedient to recognize revenue for such variable consideration, as the invoice correspondsdirectly 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 revenueRetail parts and services revenue is earned primarily on freight and crane charges that are directly reimbursable by our customers and maintenance work onunits 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 intime 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 thebenefits 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 due30 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 nomaterial obligations for returns, refunds, or warranties. Our standard contracts do not usually include material variable or non-cash consideration.Contract assets and trade accounts receivableWe record contract assets when we have completed performance under a contract but our right to consideration is not yet unconditional. We had no contractassets as of December 31, 2019 or 2018. There were no significant changes to our trade accounts receivable balances due to contract modifications or adjustments,or changes in time frame for a right to consideration to become unconditional during December 31, 2019 or 2018.Deferred revenueWe 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 2019 2018Current (1)Deferred revenue $48,289 $31,372NoncurrentOther liabilities 7,957 5,173Total $56,246 $36,545________________________________(1)All current deferred revenue as of December 31, 2018 was recognized during the year ended December 31, 2019.F-30Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsThe increase in the deferred revenue balance as of December 31, 2019 is primarily driven by an increase in cash payments received or due in advance ofsatisfying our performance obligations under contracts as compared to 2018. There was no significant change to our deferred revenue balance as a result ofchanges in time frame for a performance obligation to be satisfied during the periods presented.Performance ObligationsAs of December 31, 2019, the aggregate amount of transaction price allocated to unsatisfied performance obligations related to our contract operations revenueis $737.0 million. We expect to recognize these remaining performance obligations as follows (in thousands): 2020202120222023ThereafterTotalRemaining performance obligations$399,370 $191,741 $93,945 $34,884 $17,076 $737,016(14) Transactions with Related PartiesWe provide compression services to entities affiliated with ETO, which as of December 31, 2019, owned approximately 48% of our limited partner interestsand 100% of the General Partner.The following table summarizes the revenues from ETO on our consolidated statement of operations (in thousands): Year Ended December 31, 2019 2018Related party revenues$19,967 $17,054The USA Compression Predecessor also provided compression services to entities affiliated with ETO. During the year ended December 31, 2017, the USACompression Predecessor recognized $17.2 million in revenue from such affiliated entities.The following table summarizes accounts receivable from and accounts payable to ETO on our consolidated balance sheets (in thousands): December 31, 2019 2018Related party receivables (1)$45,461 $47,661 Related party payables (2)$1 $395________________________________(1)Related party receivables as of December 31, 2019 and 2018 from ETO included $44.9 million related to indemnification for sales tax contingencies incurred by the USACompression Predecessor. See Note 17 for more information related to such sales tax contingencies.(2)Related party payables are included in accounts payable on our consolidated balance sheets.ETO provided certain benefits to the USA Compression Predecessor employees which did not continue following the Transactions Date. ETO providedmedical, dental and other healthcare benefits to the USA Compression Predecessor employees. The total amount incurred by ETO for the benefit of the USACompression Predecessor employees for the years ended December 31, 2018 and 2017 was $1.9 million and $7.4 million, respectively, which was allocated to theUSA Compression Predecessor and recorded in operation and maintenance and general and administrative expenses, as appropriate. ETO also provided a matchingcontribution to the USA Compression Predecessor employees’ 401(k) accounts. The total amount of matching contributions incurred for the benefit of the USACompression Predecessor employees for the years ended December 31, 2018 and 2017 was $0.9 million and $3.0 million, respectively, which was allocated to theUSA Compression Predecessor and recorded in operation and maintenance and general and administrative expenses, as appropriate. ETO also provided a 3% profitsharing contribution to the 401(k) accounts for all USA Compression Predecessor employees with base compensation below a specified threshold. The contributionwas inF-31Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statementsaddition to the 401(k) matching contribution and employees became vested in the profit sharing contribution based on years of service.ETO allocated certain overhead costs associated with general and administrative services, including salaries and benefits, facilities, insurance, informationservices, human resources and other support departments to the USA Compression Predecessor which did not continue following the Transactions Date. Wherecosts incurred on the USA Compression Predecessor’s behalf could not be determined by specific identification, the costs were primarily allocated to the USACompression Predecessor based on an average percentage of fixed assets, net income (loss) and Adjusted EBITDA. The USA Compression Predecessor believesthese allocations were a reasonable reflection of the utilization of services provided. However, the allocations may not fully reflect the expenses that would havebeen incurred had the USA Compression Predecessor been a standalone company during the periods presented. During the years ended December 31, 2018 and2017, ETO allocated general and administrative expenses of $1.8 million and $3.6 million, respectively, to the USA Compression Predecessor.Pursuant to that certain Board Representation Agreement entered into by us, the General Partner, ET LP and EIG in connection with our private placement ofPreferred 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 thePreferred Units hold more than 5% of the Partnership’s outstanding common units in the aggregate (taking into account the common units that would be issuableupon conversion of the Preferred Units and exercise of the Warrants).(15)Unit-Based CompensationLong-Term Incentive PlanIn connection with the Partnership’s initial public offering in January 2013, the board of directors of the General Partner (the “Board”) adopted the USACompression Partners, LP 2013 Long-Term Incentive Plan (“LTIP”) for certain employees, consultants and directors of the General Partner and any of its affiliateswho perform services for us. The LTIP provides for awards of unit options, unit appreciation rights, restricted units, phantom units, distribution equivalent rights(“DERs”), unit awards, profits interest units and other unit-based awards. On November 1, 2018 and effective the same day, the Board approved and adopted TheFirst Amendment to the LTIP which, among other things, increased the number of common units of the Partnership available to be awarded under the LTIP by8,590,000 common units (which brought the total number of common units available to be awarded under the LTIP to 10,000,000 common units) and extended theterm of the LTIP until November 1, 2028. Awards that are forfeited, canceled, paid or otherwise terminate or expire without the actual delivery of common unitswill 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 tohelp 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 cashand 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’sminimum statutory tax-withholding rate. ASC Topic 718, Compensation-Stock Compensation, requires the entire amount of an award with such features to beaccounted 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 financialstatement 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 requisiteservice period (the vesting period of the awards), compensation cost is recognized using the proportionate amount of the award’s fair value that has been earnedthrough 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 theproduct of (a) the number of the recipient’s outstanding, unvested phantom units on the record date for such quarter and (b) the quarterly distribution declared bythe Board for such quarter with respect to the Partnership’s common units.During the year ended December 31, 2019 and the period from the Transactions Date to December 31, 2018, an aggregate of 717,869 and 1,136,447,respectively, phantom units (including the corresponding DERs) were granted under the LTIP to the General Partner’s executive officers and certain of itsemployees and independent directors. The phantom units (including the corresponding DERs) awarded are subject to restrictions on transferability, customaryforfeiture provisions and time vesting provisions. Phantom unit awards granted after July 30, 2018 vest incrementally, with 60% of the phantom units vesting at theend of the third year following the grant and the remaining 40% vesting at the end of the fifth year following the grant. Phantom unit awards that were granted toemployees of USAC Management prior to July 30, 2018 vest evenly over a three-year service period.F-32Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsPhantom units granted prior to July 30, 2018 vest in full in the event of a change in control followed by a termination of employment, and phantom unitsgranted 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 tothe phantom units until the units have vested.On the Transactions Date and in connection with the closing of the CDM Acquisition, and pursuant to the change in control provisions of our outstandingphantom unit awards, all of the performance-based phantom units granted during 2018, 2017 and 2016 and outstanding as of the Transactions Date, vestedimmediately upon the change in control event at 100% of the target level. In addition, all outstanding time-based phantom units held by our CEO vestedimmediately upon the change in control event. As such, 563,544 outstanding phantom units vested resulting in $6.8 million of compensation expense recognizedduring the year ended December 31, 2018.ETO had a long-term incentive plan for the USA Compression Predecessor’s employees, officers and directors. ETO had granted restricted unit awards to theUSA Compression Predecessor’s employees that vested on a pro-rata basis incrementally over a five-year vesting period, with vesting based on continuedemployment as of each applicable vesting date. Upon vesting, ETO common units were issued. These restricted unit awards also entitled the recipients of the unitawards to receive, with respect to each ETO common unit subject to such award that had not vested or been forfeited, a corresponding DER entitling the recipientto a cash payment equal to the cash distribution per ETO common unit paid by ETO to its unitholders promptly following each such distribution. All unit-basedcompensation awards were treated as equity within the USA Compression Predecessor financial statements.The unit and per-unit amounts disclosed in the remainder of this note for periods prior to the Transactions Date reflect amounts related to ETO. These amountshave been retrospectively adjusted to reflect a 1.5 to one unit-for-unit exchange related to the merger of ETO and Sunoco Logistics Partners L.P. in April 2017 anda 0.4124 to one unit-for unit exchange related to the merger of ETO and Regency Energy Partners LP in April 2015. The unit and per-unit amounts do not reflectthe conversion of ETO units to ET LP units as a result of the ETE Merger in October 2018.On the Transactions Date and in connection with the closing of the CDM Acquisition, and pursuant to the change in control provisions of the USACompression Predecessor’s outstanding phantom unit awards, all of the USA Compression Predecessor’s outstanding phantom unit awards were forfeited.As of December 31, 2019 and 2018, our total unit-based compensation liability was $7.1 million and $3.6 million, respectively. During the years endedDecember 31, 2019, 2018 and 2017, we recognized $10.8 million, $11.7 million and $4.0 million of compensation expense associated with these awards,respectively, recorded in selling, general and administrative expense. During the years ended December 31, 2019 and 2018, amounts paid related to the cashsettlement of vested awards under the LTIP were $1.7 million and $4.4 million, respectively. During the year ended December 31, 2017, amounts paid related tothe cash settlement of vested awards by the USA Compression Predecessor were $0.6 million.The total fair value and intrinsic value of the phantom units vested under the LTIP was $4.6 million and $9.7 million for the year ended December 31, 2019and for the period from the Transactions Date to December 31, 2018, respectively, and $1.6 million during the year ended December 31, 2017.F-33Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsThe following table summarizes information regarding phantom unit awards for the periods presented: Number of Units Weighted-Average Grant Date Fair Value per UnitUSA Compression Predecessor's phantom units outstanding at December 31, 2016429,535 $29.34Granted2,500 18.75Vested(95,499) 36.94Forfeited(11,614) 27.41USA Compression Predecessor's phantom units outstanding at December 31, 2017324,922 $27.10Forfeited upon change in control, April 2, 2018(324,922) 27.10Assumed upon change in control, April 2, 2018 (1)1,010,522 14.24Granted (1)1,136,447 15.47Vested (1)(571,892) 14.79Forfeited (1)(144,013) 17.85Phantom units outstanding at December 31, 20181,431,064 $14.98Granted717,869 15.88Vested(301,329) 13.06Forfeited(45,620) 16.78Phantom units outstanding at December 31, 20191,801,984 $15.09________________________________(1)Following the Transactions Date, the outstanding unvested phantom units granted by the USA Compression Predecessor were forfeited and the outstanding unvestedphantom units granted by the Partnership prior to the Transactions Date were maintained. The number of units assumed upon change in control represent the Partnership’sunvested outstanding phantom units as of March 31, 2018. The subsequent number of units granted, vested and forfeited reflect activity following the Transactions Datethrough December 31, 2018.The unrecognized compensation cost associated with phantom unit awards was an aggregate $25.3 million as of December 31, 2019. We expect to recognizethe unrecognized compensation cost for these awards on a weighted-average basis over a period of 3.0 years.(16)Employee BenefitPlansA 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$19,000 for 2019. The plan provides for discretionary matching contributions by us on an annual basis. Aggregate matching contributions made to employees’401(k) plans were $3.4 million for the year ended December 31, 2019 and $3.2 million for the year ended December 31, 2018, including $0.9 million made byETO to employees of the USA Compression Predecessor prior to the Transactions Date.Refer to Note 14 for information about the 401(k) plan provided by ETO to employees of the USA Compression Predecessor.(17)Commitments and Contingencies(a)Major CustomersNeither we nor the USA Compression Predecessor had revenue from any single customer representing 10% or more of total revenue for the years endedDecember 31, 2019, 2018 or 2017.(b)LitigationFrom time to time, we and our subsidiaries may be involved in various claims and litigation arising in the ordinary course of business. In management’sopinion, 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.F-34Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial Statements(c)Equipment PurchaseCommitmentsOur future capital commitments are comprised of binding commitments under purchase orders for new compression units ordered but not received. Thecommitments as of December 31, 2019 were $49.3 million, all of which is expected to be settled within the next twelve months.(d)Sales TaxContingenciesOur compliance with state and local sales tax regulations is subject to audit by various taxing authorities. The Office of the Texas Comptroller of PublicAccounts (“Comptroller”) has claimed that specific operational processes, which we and others in our industry regularly conduct, result in transactions that aresubject to state sales taxes. We and other companies in our industry have disputed these claims based on existing tax statutes which provide for manufacturingexemptions on the transactions in question. The manufacturing exemptions are based on the fact that our natural gas compression equipment is used in the processof treating natural gas for ultimate use and sale.The USA Compression Predecessor has several open audits with the Comptroller for certain periods prior to the Transactions Date wherein the Comptrollerhas challenged the applicability of the manufacturing exemption. Any liability for the periods prior to the Transactions Date will be covered by an indemnitybetween us and ETO. As of December 31, 2019 and 2018, we have recorded a $44.9 million accrued liability and $44.9 million related party receivable fromETO.During January 2020, we entered into a compromise and settlement agreement with the Comptroller for the audit of the USA Compression Predecessor for theperiod from August 2006 to December 2007 for $4.0 million to be paid by the USA Compression Predecessor’s former owner. As of December 31, 2019, we haverecorded a $4.0 million asset from the USA Compression Predecessor’s former owner in other accounts receivable and a $4.0 million liability in accrued liabilitiesin our consolidated balance sheets. The payment was made in February 2020.(e)Self-InsuranceEffective January 1, 2019, we became self-insured for medical claims up to certain stop loss limits. Liabilities are accrued for self-insured claims whensufficient information is available to reasonably estimate the amount of the loss. As of December 31, 2019, we have recorded a $0.6 million accrued liability.(f)EnvironmentalThe Partnership’s operations are subject to federal, state and local laws and rules and regulations regarding water quality, hazardous and solid wastemanagement, air quality control and other environmental matters. These laws, rules and regulations require the Partnership to conduct its operations in a specifiedmanner and to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections and other approvals. Failure to comply withapplicable environmental laws, rules and regulations may expose the Partnership to significant fines, penalties and/or interruptions in operations. The Partnership’senvironmental policies and procedures are designed to achieve compliance with such applicable laws and regulations. These evolving laws and regulations andclaims for damages to property, employees, other persons and the environment resulting from current or past operations may result in significant expenditures andliabilities in the future.(18)Recent Accounting PronouncementsIn June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (“ASC Topic 326”): Measurement of Credit Losses on FinancialInstruments. The amendments to ASC Topic 326 require immediate recognition of estimated credit losses expected to occur over the remaining life of manyfinancial assets. The amendments in this update are effective for interim and annual periods beginning after January 1, 2020, with early adoption permitted by oneyear. We adopted this new standard on January 1, 2020 and our adoption of this standard did not have a material impact on our consolidated financial statements.In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (“ASC Topic 820”): Disclosure Framework-Changes to the DisclosureRequirements for Fair Value Measurement. The amendments to ASC Topic 820 eliminate, add and modify certain disclosure requirements for fair valuemeasurements as part of the FASB’s disclosure framework project. The amendments in this update are effective for interim and annual periods beginning onJanuary 1, 2020, with early adoption permitted. We adopted this new standard on January 1, 2020 and the impact to our disclosures will not be material and therewas no impact to our consolidated financial statements.F-35Table of ContentsUSA COMPRESSION PARTNERS, LPNotes to Consolidated Financial StatementsIn August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (“ASC Subtopic 350-40”): Customer’s Accountingfor Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.

The following summary does not purport to be complete and is qualified in its entirety by reference tothe provisions of applicable law and to our partnership agreement. References to our “general partner” refer to USA Compression GP, LLC, a Delaware limitedliability company and our general partner.Common UnitsThe common units represent limited partner interests in us. Holders of common units are entitled to receive partnership distributions and exercise the rights orprivileges available to limited partners under our partnership agreement. For a description of the rights and preferences of holders of common units in and todistributions, please read this section and “How We Make Cash Distributions.” For a description of voting rights, rights of distribution upon liquidation and otherrights and privileges of limited partners, including our common unitholders, under our partnership agreement, please read “The Partnership Agreement.”Transfers of Common UnitsBy transfer of common units in accordance with our partnership agreement, each transferee of common units shall be admitted as a limited partner withrespect to the common units transferred when such transfer and admission are reflected in our books and records. Each transferee:•represents that the transferee has the capacity, power and authority to become bound by our partnershipagreement;•automatically becomes bound by the terms and conditions of, and is deemed to have executed, our partnership agreement;and•gives the consents, waivers and approvals contained in our partnershipagreement.Our general partner will cause any transfers to be recorded on our books and records no less frequently than quarterly.We may, at our discretion, treat the nominee holder of a common unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely tothose that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.Common units are securities and any transfers are subject to the laws governing the transfer of securities. In addition to other rights acquired upon transfer, thetransferor gives the transferee the right to become a substituted limited partner in our partnership for the transferred common units.Until a common unit has been transferred on our books, we and the transfer agent may treat the record holder of the common unit as the absolute owner for allpurposes, except as otherwise required by law or stock exchange regulations.How We Make Cash DistributionsSet forth below is a summary of the significant provisions of our partnership agreement that relate to cash distributions.Distributions of Available CashGeneral. Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash to unitholders of recordon the applicable record date.Definition of available cash. Available cash, for any quarter, consists of all cash on hand at the end of that quarter:•less, the amount of cash reserves established by our general partnerto:•provide for the proper conduct of ourbusiness;•comply with applicable law, our revolving credit facility or other agreements;and•provide funds for distributions to our unitholders for any one or more of the next fourquarters;•plus, if our general partner so determines, all or a portion of cash on hand on the date of determination of available cash for the quarter resulting fromworking capital borrowings made after the end of the quarter.Working capital borrowings are borrowings that are made under a credit facility, commercial paper facility or similar financing arrangement, and in all cases,are used solely for working capital purposes or to pay distributions to partners and with the intent of the borrower to repay such borrowings within twelve monthsfrom sources other than additional working capital borrowings.Series A Preferred Units. Record holders of the Series A preferred units are entitled to receive cumulative quarterly distributions equal to $24.375 perSeries A preferred unit. We cannot pay any distributions on any junior securities, including any of the common units, prior to paying the quarterly distributionpayable on the Series A preferred units, including any previously accrued and unpaid distributions thereon.Operating Surplus and Capital SurplusGeneral. All cash distributed will be characterized as either “operating surplus” or “capital surplus.” Our partnership agreement requires that we distributeavailable cash from operating surplus differently than available cash from capital surplus.Operating surplus. Operating surplus for any period consists of:•$36.6 million (as described below); plus•all of our cash receipts beginning January 18, 2013, the closing date of our initial public offering (our “IPO”), excluding cash from interim capitaltransactions, which include the following:•borrowings (including sales of debt securities) that are not working capitalborrowings;•sales of equityinterests;•sales or other dispositions of assets outside the ordinary course of business;and•capital contributions received;provided that cash receipts from the termination of a commodity hedge or interest rate hedge prior to its specified termination date shall be included inoperating surplus in equal quarterly installments over the remaining scheduled life of such commodity hedge or interest rate hedge; plus•working capital borrowings made after the end of the period but on or before the date of determination of operating surplus for the period; plus•cash distributions paid on equity issued to finance all or a portion of the construction, acquisition or improvement of a capital improvement (such asequipment or facilities) in respect of the period beginning on the date that we enter into a binding obligation to commence the construction, acquisition orimprovement of a capital improvement and ending on the earlier to occur of the date the capital improvement or capital asset commences commercialservice and the date that it is abandoned or disposed of; plus•cash distributions paid on equity issued to pay the construction period interest on debt incurred, or to pay construction period distributions on equityissued, to finance the capital improvements referred to above; less•all of our operating expenditures (as defined below) after the closing of ourIPO; less•the amount of cash reserves established by our general partner to provide funds for future operatingexpenditures; less•all working capital borrowings not repaid within twelve months after having beenincurred; less•any loss realized on disposition of an investment capitalexpenditure.As described above, operating surplus does not reflect actual cash on hand that is available for distribution to our unitholders and is not limited to cashgenerated by our operations. For example, it includes a basket of $36.6 million that will enable us, if we choose, to distribute as operating surplus cash we receivein the future from non-operating sources such as asset sales, issuances of securities and long-term borrowings that would otherwise be distributed as capitalsurplus. In addition, the effect of including, as described above, certain cash distributions on equity interests in operating surplus will be to increase operatingsurplus by the amount of any such cash distributions. As a result, we may also distribute as operating surplus up to the amount of any such cash that we receivefrom non-operating sources.The proceeds of working capital borrowings increase operating surplus and repayments of working capital borrowings are generally operating expenditures, asdescribed below, and thus reduce operating surplus when made. However, if a working capital borrowing is not repaid during the twelve-month period followingthe borrowing, it will be deemed repaid at the end of such period, thus decreasing operating surplus at such time. When such working capital borrowing is in factrepaid, it will be excluded from operating expenditures because operating surplus will have been previously reduced by the deemed repayment.We define operating expenditures in the partnership agreement, and it generally means all of our cash expenditures, including, but not limited to, taxes,reimbursement of expenses to our general partner and its affiliates, payments made under interest rate hedge agreements or commodity hedge contracts(provided that (i) with respect to amounts paid in connection with the initial purchase of an interest rate hedge contract or a commodity hedge contract, suchamounts will be amortized over the life of the applicable interest rate hedge contract or commodity hedge contract and (ii) payments made in connection with thetermination of any interest rate hedge contract or commodity hedge contract prior to the expiration of its stipulated settlement or termination date will be includedin operating expenditures in equal quarterly installments over the remaining scheduled life of such interest rate hedge contract or commodity hedge contract),officer compensation, repayment of working capital borrowings, debt service payments and maintenance capital expenditures (as defined below), provided thatoperating expenditures will not include:•repayment of working capital borrowings deducted from operating surplus pursuant to the penultimate bullet point of the definition of operating surplusabove when such repayment actually occurs;•payments (including prepayments and prepayment penalties) of principal of and premium on indebtedness, other than working capitalborrowings;•expansion capital expenditures (as definedbelow);•investment capital expenditures (as definedbelow);•payment of transaction expenses relating to interim capital transactions;•distributions to our partners;or•repurchases of equity interests except to fund obligations under employee benefitplans. Capital surplus. Capital surplus is defined in our partnership agreement as any distribution of available cash in excess of our cumulative operating surplus.Accordingly, capital surplus would generally be generated by:•borrowings other than working capitalborrowings;•sales of our equity and debt securities;and•sales or other dispositions of assets for cash, other than inventory, accounts receivable and other assets sold in the ordinary course of business or as part ofnormal retirement or replacement of assets.Characterization of cash distributions. Our partnership agreement requires that we treat all available cash distributed as coming from operating surplus untilthe sum of all available cash distributed since January 18, 2013, the closing date of our IPO, equals the operating surplus from January 18, 2013 through the end ofthe quarter immediately preceding that distribution. Our partnership agreement requires that we treat any amount distributed in excess of operating surplus,regardless of its source, as capital surplus. We do not anticipate that we will make any distributions from capital surplus.Capital ExpendituresMaintenance capital expenditures are those capital expenditures required to maintain our long-term operating capacity and/or operating income. Capitalexpenditures made solely for investment purposes will not be considered maintenance capital expenditures.Expansion capital expenditures are those capital expenditures that we expect will increase our operating capacity or operating income over the long term.Expansion capital expenditures will also include interest (and related fees) on debt incurred to finance all or any portion of the construction of such capitalimprovement in respect of the period that commences when we enter into a binding obligation to commence construction of a capital improvement and ending onthe earlier to occur of the date any such capital improvement commences commercial service and the date that it is abandoned or disposed of. Capital expendituresmade solely for investment purposes will not be considered expansion capital expenditures.Investment capital expenditures are those capital expenditures that are neither maintenance capital expenditures nor expansion capital expenditures.Investment capital expenditures largely will consist of capital expenditures made for investment purposes. Examples of investment capital expenditures includetraditional capital expenditures for investment purposes, such as purchases of securities, as well as other capital expenditures that might be made in lieu of suchtraditional investment capital expenditures, such as the acquisition of a capital asset for investment purposes or development of facilities that are in excess of themaintenance of our existing operating capacity or operating income, but which are not expected to expand, for more than the short term, our operating capacity oroperating income.As described above, neither investment capital expenditures nor expansion capital expenditures will be included in operating expenditures, and thus will notreduce operating surplus. Because expansion capital expenditures include interest payments (andrelated fees) on debt incurred to finance all or a portion of the construction or improvement of a capital asset (such as gathering compressors) in respect of theperiod that begins when we enter into a binding obligation to commence construction of the capital asset and ends on the earlier to occur of the date the capital assetcommences commercial service or the date that it is abandoned or disposed of, such interest payments are also not subtracted from operating surplus. Losses ondisposition of an investment capital expenditure will reduce operating surplus when realized and cash receipts from an investment capital expenditure will betreated as a cash receipt for purposes of calculating operating surplus only to the extent the cash receipt is a return on principal.Capital expenditures that are made in part for maintenance capital purposes, investment capital purposes and/or expansion capital purposes will be allocated asmaintenance capital expenditures, investment capital expenditures or expansion capital expenditures by our general partner.Distributions of Available Cash from Operating SurplusOur partnership agreement requires that we make distributions or payments of available cash from operating surplus for any quarter in the following manner:•first, as distributions or payments with respect to the Series A preferred units (as described above under “-Distributions of Available Cash”);and•thereafter, to the holders of common units, prorata.Distributions from Capital SurplusHow distributions from capital surplus will be made. Our partnership agreement generally provides that we may not declare or pay any distribution fromcapital surplus without the affirmative vote of the holders of at least 662/3% of the Series A preferred units. In the event a distribution from capital surplus is soapproved, we may make distributions of available cash from capital surplus, as if they were from operating surplus.General Partner InterestOur general partner owns a non-economic general partner interest in us, which does not entitle it to receive cash distributions. However, to the extent ourgeneral partner owns common units or other equity securities in us, it is entitled to receive cash distributions on any such interests. Similarly, to the extent ourgeneral partner owns units that have voting rights, it is entitled to exercise its voting power with respect to such interests.Distributions of Cash upon LiquidationIf we dissolve in accordance with our partnership agreement, we will sell or otherwise dispose of our assets in a process called a liquidation. We will firstapply the proceeds of liquidation to the payment of our creditors. We will distribute any remaining proceeds to the unitholders, in accordance with their capitalaccount balances, as adjusted to reflect any gain or loss upon the sale or other disposition of our assets in liquidation; provided, that any cash or cash equivalents fordistributions shall be distributed with respect to the Series A preferred units (up to the positive balance in the associated capital accounts), prior to any distributionof cash or cash equivalents with respect to our common units or other junior securities.The Partnership AgreementThe following is a summary of certain material provisions of our partnership agreement that relate to ownership of our common units.Capital ContributionsUnitholders are not obligated to make additional capital contributions, except as described below under “– Limited Liability.”For a discussion of our general partner’s right to purchase common units or other partnership interests we may issue to maintain its current percentage interestif we issue additional common units or other partnership interests, please read “– Issuance of Additional Partnership Interests.”Voting RightsThe following is a summary of the unitholder vote required for approval of the matters specified below. Matters that require the approval of a “unit majority”require the approval of a majority of the common units.In voting their units, our general partner and its affiliates have no fiduciary duty or obligation whatsoever to us or the limited partners, including any duty toact in good faith or in the best interests of us or the limited partners.Issuance of additional units No approval right, subject to certain limitations on issuing units ranking senior to, or pari passu with, theSeries A preferred units without the approval of the holders of 662/3% or more of the outstandingSeries A preferred units, voting separately as a class.Amendment of our partnership agreement Certain amendments may be made by our general partner without the approval of unitholders. Otheramendments generally require the approval of a unit majority or at least the requisite percentage of thetype or class of limited partner interests materially and adversely affected by the amendment. Please read“-Amendment of the Partnership Agreement.”Merger of our partnership or the sale of all orsubstantially all of our assets Unit majority in certain circumstances. Please read “-Merger, Sale or Other Disposition of Assets.”Dissolution of our partnership Unit majority. Please read “-Dissolution.”Continuation of our business upon dissolution Unit majority. Please read “-Dissolution.”Withdrawal of our general partner Under most circumstances, the approval of a majority of the common units, excluding common unitsheld by our general partner and its affiliates, is required for the withdrawal of our general partner prior toDecember 31, 2022 in a manner that would cause a dissolution of our partnership. Please read “-Withdrawal or Removal of Our General Partner.”Removal of our general partner Not less than 662/3% of the outstanding units (excluding Series A preferred units), voting as a singleclass, including units held by our general partner and its affiliates. Please read “-Withdrawal or Removalof Our General Partner.”Transfer of our general partner interest Our general partner may transfer all, but not less than all, of its general partner interest in us without avote of our unitholders to an affiliate or another person in connection with its merger or consolidationwith or into, or sale of all or substantially all of its assets to, such person. The approval of a majority ofthe common units, excluding common units held by our general partner and its affiliates, is required inother circumstances for a transfer of the general partner interest to a third party prior to December 31,2022.Transfer of ownership interests in our general partner No approval right. If any person or group other than our general partner and its affiliates acquires beneficial ownership of 20% or more of any class of units, that person orgroup loses voting rights on all of its units. This loss of voting rights does not apply to any person or group that acquires the units from our general partner, itsaffiliates, their direct transferees and their indirect transferees approved by our general partner in its sole discretion or to any person or group who acquires theunits with the specific prior approval of our general partner.Applicable Law; Forum, Venue and JurisdictionOur partnership agreement is governed by Delaware law. Our partnership agreement requires that any claims, suits, actions or proceedings:•arising out of or relating in any way to the partnership agreement (including any claims, suits or actions to interpret, apply or enforce the provisions of thepartnership agreement), any partnership interest or the duties, obligations or liabilities among limited partners or of limited partners, or the rights orpowers of, or restrictions on, the limited partners or us;•asserting a claim arising pursuant to any provision of the Delaware Revised Uniform Limited Partnership Act, or the Delaware Act, or other similarapplicable statutes;•asserting a claim arising out of any other instrument, document, agreement or certificate contemplated by any provision of the Delaware Act relating tothe Partnership or the partnership agreement; and•arising out of the federal securities laws of the U.S. or securities or antifraud laws of any governmental authority shall be exclusively brought in the Courtof Chancery of the State of Delaware or if such court does not have subject matter jurisdiction, any other court located in the State of Delaware withsubject matter jurisdiction, regardless of whether such claims, suits, actions or proceedings sound in contract, tort, fraud or otherwise, are based oncommon law, statutory, equitable, legal or other grounds, or are derivative or direct claims.The exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act of 1933, as amended (the“Securities Act”), or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any other claim for which the federal courts have exclusivejurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over allsuits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Actcreates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules andregulations thereunder.By purchasing a common unit, a limited partner is irrevocably consenting to these limitations and provisions regarding claims, suits, actions or proceedingsand submitting to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, or if such court does not have subject matter jurisdiction, any othercourt located in the State of Delaware with subject matter jurisdiction in connection with any such claims, suits, actions or proceedings.Limited LiabilityAssuming that a limited partner does not participate in the control of our business within the meaning of the Delaware Act and that he otherwise acts inconformity with the provisions of the partnership agreement, his liability under the Delaware Act is limited, subject to possible exceptions, to the amount of capitalhe is obligated to contribute to us for his common units plus his share of any undistributed profits and assets. However, if a court were to determine that the right,or exercise of the right, by the limited partners as a group to take any action under the partnership agreement constituted “participation in the control” of ourbusiness for the purposes of the Delaware Act, then the limited partners could be held personally liable for our obligations under the laws of Delaware, to the sameextent as our general partner. This liability would extend to persons who transact business with us under the reasonable belief that the limited partner is a generalpartner. Neither our partnership agreement nor the Delaware Act specifically provides for legal recourse against our general partner if a limited partner were to loselimited liability through any fault of our general partner.Under the Delaware Act, a limited partnership may not make a distribution to a partner if, after the distribution, all liabilities of the limited partnership, otherthan liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of thepartnership, would exceed the fair value of the assets of the limited partnership. For the purpose of determining the fair value of the assets of a limited partnership,the Delaware Act provides that the fair value of property subject to liability for which recourse of creditors is limited shall be included in the assets of the limitedpartnership only to the extent that the fair value of that property exceeds the nonrecourse liability. The Delaware Act provides that a limited partner who receives adistribution and knew at the time of the distribution that the distribution was in violation of the Delaware Act shall be liable to the limited partnership for theamount of the distribution for three years. Under the Delaware Act, a substituted limited partner of a limited partnership is liable for the obligations of his assignorto make contributions to the partnership, except that such person is not obligated for liabilities unknown to him at the time he became a limited partner and thatcould not be ascertained from the partnership agreement.Our subsidiaries conduct business in several states and we may have subsidiaries that conduct business in other states in the future. Maintenance of our limitedliability as a member of our operating companies may require compliance with legal requirements in the jurisdictions in which the operating company conductsbusiness, including qualifying our subsidiaries to do business there.Limitations on the liability of members or limited partners for the obligations of a limited liability company or limited partnership have not been clearlyestablished in many jurisdictions. If, by virtue of our ownership interest in our operating companies or otherwise, it were determined that we were conductingbusiness in any state without compliance with the applicable limited partnership or limited liability company statute, or that the right or exercise of the right by thelimited partners as a group to remove or replace our general partner, to approve some amendments to our partnership agreement, or to take other action under ourpartnership agreement constituted “participation in the control” of our business for purposes of the statutes of any relevant jurisdiction, then the limited partnerscould be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We willoperate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of the limited partners.Issuance of Additional Partnership InterestsOur partnership agreement authorizes us to issue an unlimited number of additional partnership interests and other equity securities that are equal in rank withor junior to our common units for the consideration and on the terms and conditions determined by our general partner without the approval of the unitholders.It is possible that we will fund acquisitions through the issuance of additional common units or other partnership interests. Holders of any additional commonunits we issue will be entitled to share equally with the then-existing holders of common unitsin our distributions of available cash. In addition, the issuance of additional common units or other partnership interests may dilute the value of the interests of thethen-existing holders of common units in our net assets.In accordance with Delaware law and the provisions of our partnership agreement, we may also issue additional partnership interests that, as determined byour general partner, may have special voting rights to which the common units are not entitled. In addition, our partnership agreement does not prohibit oursubsidiaries from issuing equity interests, which may effectively rank senior to the common units. However, our partnership agreement does prohibit us fromissuing additional partnership interests that rank senior to, or pari passu with, the Series A preferred units without the affirmative vote of 662/3% of theoutstanding Series A preferred units.Upon issuance of additional partnership interests (other than the issuance of common units upon (i) conversion of Series A preferred units and (ii) exercise ofthe Warrants (as defined below)) our general partner will have the right, which it may from time to time assign in whole or in part to any of its affiliates, topurchase common units or other partnership interests whenever, and on the same terms that, we issue those interests to persons other than our general partner andits affiliates and beneficial owners, to the extent necessary to maintain the percentage interest of the general partner and its affiliates, including such interestrepresented by common units, that existed immediately prior to each issuance. The holders of common units do not have preemptive rights under our partnershipagreement to acquire additional common units or other partnership interests.Conversion of the Series A Preferred UnitsEach unitholder who holds Series A preferred units may elect to convert its Series A preferred units into common units on a one-for-one basis as follows:•from and after April 2, 2021, 331/3% of the Series A preferred units issued on April 2, 2018 shall beconvertible;•from and after April 2, 2022, 662/3% of the Series A preferred units issued on April 2, 2018 shall be convertible;and•from and after April 2, 2023, all of the Series A preferred units shall beconvertible; provided, that,•notwithstanding the foregoing, if an ongoing default trigger (as defined under our partnership agreement) is occurring at any time, from and after theinitial occurrence of such ongoing default trigger, all of the issued and outstanding Series A preferred units shall be convertible.WarrantsWe have two tranches of warrants to purchase common units (“Warrants”) outstanding, which include Warrants to purchase 5,000,000 common units with astrike price of $17.03 per unit and 10,000,000 common units with a strike price of $19.59 per unit. The Warrants may be exercised by the holders thereof at anytime before April 2, 2028. Upon exercise of the Warrants, we may, at our option, elect to settle the Warrants in common units or cash, each on a net basis based onthe volume weighted average trading price of our common units on the exercise date.Amendment of the Partnership AgreementGeneral. Amendments to our partnership agreement may be proposed only by our general partner. However, our general partner has no duty or obligation topropose any amendment and may decline to do so free of any fiduciary duty or obligation whatsoever to us or the limited partners, including any duty to act in goodfaith or in the best interests of us or the limited partners. In order to adopt a proposed amendment, other than the amendments discussed below, our general partneris required to seek written approval of the holders of the number of units required to approve the amendment or to call a meeting of the limited partners to considerand vote upon the proposed amendment. Except as described below, an amendment must be approved by a unit majority.Prohibited amendments. No amendment may be made that would:•enlarge the obligations of any limited partner without its consent, unless approved by a majority of the type or class of limited partner interests soaffected; or•enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwisepayable by us to our general partner or any of its affiliates without the consent of our general partner, which consent may be given or withheld in its solediscretion.The provision of our partnership agreement preventing the amendments having the effects described in the bullets above can be amended upon the approval ofthe holders of at least 90% of the outstanding units, voting as a single class (including units owned by our general partner and its affiliates).In addition, no amendment may be made that is materially adverse to any of the rights, preferences and privileges of the Series A preferred units, without theapproval of the holders of 662/3% of the Series A preferred units.No unitholder approval. Our general partner may generally make amendments to our partnership agreement without the approval of any limited partner toreflect:a) a change in our name, the location of our principal place of business, our registered agent or our registered office;b) the admission, substitution, withdrawal or removal of partners in accordance with our partnership agreement;c) a change that our general partner determines to be necessary or appropriate to qualify or continue our qualification as a limited partnership or other entity inwhich the limited partners have limited liability under the laws of any state or to ensure that neither we nor any of our subsidiaries will be treated as an associationtaxable as a corporation or otherwise taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed);d) any amendments that our general partner determines:•do not adversely affect the limited partners considered as a whole (or any particular class of limited partners) in any materialrespect;•are necessary or appropriate to satisfy any requirements, conditions or guidelines contained in any opinion, directive, order, ruling or regulation ofany federal or state agency or judicial authority or contained in any federal or state statute;•are necessary or appropriate to facilitate the trading of limited partner interests or to comply with any rule, regulation, guideline or requirement ofany securities exchange on which the limited partner interests are or will be listed for trading;•are necessary or appropriate for any action taken by our general partner relating to splits or combinations of units under the provisions of ourpartnership agreement; or•are required to effect the intent expressed in the prospectus used in our IPO or the intent of the provisions of our partnership agreement or areotherwise contemplated by our partnership agreement;e) a change in our fiscal year or taxable year and related changes;f) an amendment that is necessary, in the opinion of our counsel, to prevent us or our general partner or its directors, officers, agents or trustees from in anymanner being subjected to the provisions of the Investment Company Act of 1940, the Investment Advisers Act of 1940 or “plan asset” regulations adopted underthe Employee Retirement Income Security Act of 1974, whether or not substantially similar to plan asset regulations currently applied or proposed;g) an amendment that our general partner determines to be necessary or appropriate in connection with the creation, authorization or issuance of additionalpartnership interests or the right to acquire partnership interests;h) any amendment expressly permitted in our partnership agreement to be made by our general partner acting alone;i) an amendment effected, necessitated or contemplated by a merger agreement that has been approved under the terms of our partnership agreement;j) any amendment that our general partner determines to be necessary or appropriate for the formation by us of, or our investment in, any corporation,partnership or other entity, as otherwise permitted by our partnership agreement;k) amendments to effect conversions into, mergers with or conveyances to another limited liability entity that is newly formed and has no assets, liabilities oroperations at the time of the conversion, merger or conveyance other than those it receives by way of the conversion, merger or conveyance; orl) any other amendments substantially similar to any of the matters described above.Opinion of counsel and unitholder approval. Any amendment that our general partner determines adversely affects in any material respect one or moreparticular classes of limited partners requires the approval of at least a majority of the class or classes so affected, but no vote is required by any class or classes oflimited partners that our general partner determines are not adversely affected in any material respect. Any amendment that would have a material adverse effecton the rights or preferences of any type or class of outstanding units in relation to other classes of units requires the approval of at least a majority of the type orclass of units so affected. Any amendment that is materially adverse to any of the rights, preferences and privileges of the Series A preferred units requires theapproval of at least 662/3% of the outstanding Series A preferred units, voting separately as a class.Any amendment that reduces the voting percentage required to take any action, other than to remove the general partner or call a meeting, is required to beapproved by the affirmative vote of limited partners whose aggregate outstanding units constitute not less than the voting requirement sought to be reduced. Anyamendment that increases the voting percentage required to remove the general partner or call a meeting of unitholders must be approved by the affirmative voteof limited partners whose aggregate outstanding units constitute not less than the voting requirement sought to be increased. For amendments of the type notrequiring unitholder approval, our general partner is not required to obtain an opinion of counsel that an amendment will neither result in a loss of limited liabilityto the limited partners nor result in our being treated as a taxable entity for federal income tax purposes in connection with any of the amendments. No otheramendments to our partnership agreement will become effective without the approval of holders of at least 90% of the outstanding units, voting as a single class,unless we first obtain an opinion of counsel to the effect that the amendment will not affect the limited liability under applicable law of any of our limited partners.Merger, Sale or Other Disposition of AssetsA merger, consolidation or conversion of us requires the prior consent of our general partner. However, our general partner has no duty or obligation toconsent to any merger, consolidation or conversion and may decline to do so free of any fiduciary duty or obligation whatsoever to us or the limited partners,including any duty to act in good faith or in the best interest of us or the limited partners.In addition, our partnership agreement generally prohibits our general partner, without the prior approval of the holders of a unit majority, from causing us tosell, exchange or otherwise dispose of all or substantially all of our assets in a single transaction or a series of related transactions. Our general partner may,however, mortgage, pledge, hypothecate or grant a security interest in all or substantially all of our assets without such approval. Our general partner may also sellall or substantially all of our assets under a foreclosure or other realization upon those encumbrances without such approval. Finally, our general partner mayconsummate any merger without the prior approval of our unitholders if we are the surviving entity in the transaction, our general partner has received an opinionof counsel regarding limited liability and tax matters, the transaction would not result in a material amendment to the partnership agreement (other than anamendment that the general partner could adopt without the consent of the limited partners), each of our units will be an identical unit of our partnership followingthe transaction and the partnership interests to be issued do not exceed 20% of our outstanding partnership interests immediately prior to the transaction.If the conditions specified in our partnership agreement are satisfied, our general partner may convert us or any of our subsidiaries into a new limited liabilityentity or merge us or any of our subsidiaries into, or convey all of our assets to, a newly formed entity, if the sole purpose of that conversion, merger orconveyance is to effect a mere change in our legal form into another limited liability entity, our general partner has received an opinion of counsel regardinglimited liability and tax matters and the governing instruments of the new entity provide the limited partners and our general partner with the same rights andobligations contained in our partnership agreement. Our unitholders are not entitled to dissenters’ rights of appraisal under our partnership agreement or applicableDelaware law in the event of a conversion, merger or consolidation, a sale of substantially all of our assets or any other similar transaction or event.DissolutionWe will continue as a limited partnership until dissolved under our partnership agreement. We will dissolve upon:•the election of our general partner to dissolve us, if approved by the holders of units representing a unitmajority;•there being no limited partners, unless we are continued without dissolution in accordance with applicable Delawarelaw;•the entry of a decree of judicial dissolution of our partnership;or•the withdrawal or removal of our general partner or any other event that results in its ceasing to be our general partner other than by reason of a transfer ofits general partner interest in accordance with our partnership agreement or its withdrawal or removal following the approval and admission of asuccessor. Upon a dissolution under the last clause above, the holders of a unit majority may also elect, within specific time limitations, to continue our business on thesame terms and conditions described in our partnership agreement by appointing as a successor general partner an entity approved by the holders of unitsrepresenting a unit majority, subject to our receipt of an opinion of counsel to the effect that:•the action would not result in the loss of limited liability under Delaware law of any limited partner;and•neither our partnership, our operating companies nor any of our other subsidiaries would be treated as an association taxable as a corporation orotherwise be taxable as an entity for federal income tax purposes upon the exercise of that right to continue (to the extent not already so treated or taxed).Liquidation and Distribution of ProceedsUpon our dissolution, unless our business is continued, the liquidator authorized to wind up our affairs will, acting with all of the powers of our generalpartner that are necessary or appropriate, liquidate our assets and apply the proceeds of the liquidation as described in “How We Make Cash Distributions-Distributions of Cash Upon Liquidation.” The liquidator may defer liquidation or distribution of our assets for a reasonable period of time or distribute assets topartners in-kind if it determines that a sale would be impractical or would cause undue loss to our partners.Withdrawal or Removal of Our General PartnerExcept as described below, our general partner has agreed not to withdraw voluntarily as our general partner prior to December 31, 2022 without obtaining theapproval of the holders of a majority of the outstanding common units, excluding common units held by our general partner and its affiliates, and furnishing anopinion of counsel regarding limited liability and tax matters. On or after December 31, 2022 our general partner may withdraw as general partner without firstobtaining approval of any unitholder by giving 90 days' written notice, and that withdrawal will not constitute a violation of our partnership agreement.Notwithstanding the information above, our general partner may withdraw without unitholder approval upon 90 days' notice to the limited partners if at least 50%of the outstanding common units are held or controlled by one person and its affiliates, other than our general partner and its affiliates. In addition, our partnershipagreement permits our general partner, in some instances, to sell or otherwise transfer all of its general partner interest in us without the approval of the unitholders.Upon withdrawal of our general partner under any circumstances, other than as a result of a transfer by our general partner of all or a part of its general partnerinterest in us, the holders of a unit majority may select a successor to that withdrawing general partner. If a successor is not elected, or is elected but an opinion ofcounsel regarding limited liability and tax matters cannot be obtained, we will be dissolved, wound up and liquidated, unless within a specified period after thatwithdrawal, the holders of a unit majority agree in writing to continue our business and to appoint a successor general partner. Please read “-Dissolution.”Our general partner may not be removed unless that removal is approved by the vote of the holders of not less than 662/3% of the outstanding units(excluding Series A preferred units), voting together as a single class, including units held by our general partner and its affiliates, and we receive an opinion ofcounsel regarding limited liability and tax matters. Any removal of our general partner is also subject to the approval of a successor general partner by the vote ofthe holders of a majority of the outstanding common units, voting as a class. The ownership of more than 331/3% of the outstanding units by our general partnerand its affiliates gives them the ability to prevent our general partner’s removal. In the event of the removal of our general partner under circumstances where cause exists or withdrawal of our general partner where that withdrawal violatesour partnership agreement, a successor general partner will have the option to purchase the general partner interest of the departing general partner for a cashpayment equal to the fair market value of those interests. Under all other circumstances where our general partner withdraws or is removed by the limited partners,the departing general partner has the option to require the successor general partner to purchase the general partner interest of the departing general partner or itsaffiliates for fair market value. In each case, this fair market value will be determined by agreement between the departing general partner and the successor generalpartner. If no agreement is reached, an independent investment banking firm or other independent expert selected by the departing general partner and thesuccessor general partner will determine the fair market value. Or, if the departing general partner and the successor general partner cannot agree upon an expert,then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.If the option described above is not exercised by either the departing general partner or the successor general partner, the departing general partner’s generalpartner interest will automatically convert into common units equal to the fair market value of those interests as determined by an investment banking firm or otherindependent expert selected in the manner described in the preceding paragraph.In addition, we will be required to reimburse the departing general partner for all amounts due the departing general partner, including, without limitation, allemployee-related liabilities, including severance liabilities incurred as a result of the termination of any employees employed for our benefit by the departinggeneral partner or its affiliates.Change of Management ProvisionsOur partnership agreement contains specific provisions that are intended to discourage a person or group from attempting to remove USACompression GP, LLC as our general partner or from otherwise changing our management. Please read “-Withdrawal or Removal of Our General Partner” for adiscussion of certain consequences of the removal of our general partner. If any person or group, other than our general partner and its affiliates, acquiresbeneficial ownership of 20% or more of any class of units, that person or group loses voting rights on all of its units, subject to certain exceptions. This loss ofvoting rights does not apply in certain circumstances. Please read “-Voting Rights.”Limited Call RightIf at any time our general partner and its affiliates own more than 80% of the then-issued and outstanding limited partner interests of any class (excludingSeries A preferred units), our general partner will have the right, which it may assign in whole or in part to any of its affiliates or beneficial owners thereof or to us,to acquire all, but not less than all, of the limited partner interests of the class held by unaffiliated persons as of a record date to be selected by our general partner,on at least 10, but not more than 60, days’ notice. The purchase price in the event of this purchase is the greater of:•the highest price paid by our general partner or any of its affiliates for any limited partner interests of the class purchased within the 90 days preceding thedate on which our general partner first mails notice of its election to purchase those limited partner interests; and•the average of the daily closing prices of the partnership securities of such class over the 20 trading days preceding the date three days before the date thenotice is mailed.As a result of our general partner’s right to purchase outstanding limited partner interests, a holder of limited partner interests may have his limited partnerinterests purchased at an undesirable time or a price that may be lower than market prices at various times prior to such purchase or lower than a unitholder mayanticipate the market price to be in the future. The tax consequences to a unitholder of the exercise of this call right are the same as a sale by that unitholder of hiscommon units in the market.Non-Citizen Assignees; RedemptionIf we are or become subject to federal, state or local laws or regulations that, in the reasonable determination of the general partner, create a substantial risk ofcancellation or forfeiture of any property that we have an interest in because of the nationality, citizenship or other related status of any limited partner or assignee,we may redeem the units held by the limited partner or assignee at their current market price. In order to avoid any cancellation or forfeiture, the general partnermay require each limited partner or assignee to furnish information about his nationality, citizenship or related status.
