Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Unless otherwise indicated, the terms “our,” “we,” “us,” “the Partnership” and similar language refer to USA Compression Partners, LP, collectively with its consolidated subsidiaries. We are a Delaware limited partnership. Through our operating subsidiaries, we provide compression services under fixed-term contracts with customers in the natural gas and crude oil industries, using natural gas compression packages that we design, engineer, own, operate and maintain. We also own and operate a fleet of equipment used to provide natural gas treating services, such as carbon dioxide and hydrogen sulfide removal, cooling, and dehydration. We primarily provide compression services in a number of shale plays throughout the U.S., including the Utica, Marcellus, Permian Basin, Delaware Basin, Eagle Ford, Mississippi Lime, Granite Wash, Woodford, Barnett, Haynesville, Niobrara and Fayetteville shales. USA Compression GP, LLC, a Delaware limited liability company, serves as our general partner and is referred to herein as the “General Partner.” The General Partner is wholly owned by Energy Transfer. The Partnership is a borrower under a revolving credit facility and its subsidiaries are guarantors of that revolving credit facility (see Note 9). The accompanying consolidated financial statements include the accounts of the Partnership and its subsidiaries, all of which are wholly owned by us. Net loss attributable to partners is allocated to our common units and participating securities using the two-class income allocation method. All intercompany balances and transactions have been eliminated in consolidation. Our common units trade on the New York Stock Exchange under the ticker symbol “USAC”. USA Compression Management Services, LLC (“USAC Management”), a wholly owned subsidiary of the General Partner, performs certain management and other administrative services for us, such as accounting, corporate development, finance and legal.

Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies

Basis of Presentation and Accounting Policies

Basis of Presentation

Our accompanying consolidated financial statements have been prepared in conformity with GAAP and pursuant to the rules and regulations of the SEC.

Use of Estimates

The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and the accompanying results. Although these estimates are based on management’s available knowledge of current and expected future events, actual results could differ from these estimates.

Accounting Policies

Cash and Cash Equivalents

Cash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of 90 days or less to be cash equivalents.

Trade Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount.

Allowance for Credit Losses

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (“Topic 326”): Measurement of Credit Losses on Financial Instruments. On January 1, 2020, we adopted Topic 326 using the modified retrospective approach, which was effective for interim and annual reporting periods beginning on or after December 15, 2019. Topic 326 requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets.

To adopt Topic 326, we evaluated our allowance for credit losses related to our two financial assets measured at amortized cost: (i) trade accounts receivable and (ii) net investment in lease related to our sales-type lease discussed further in Note 7. Due to the short-term nature of our trade accounts receivable, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. There was no cumulative effect adjustment to partners’ capital upon adoption.

Our determination of the allowance for credit losses requires us to make estimates and judgments regarding our customers’ ability to pay amounts due. We continuously evaluate the financial strength of our customers and the overall business climate in which our customers operate, and make adjustments to the allowance for credit losses as necessary. We evaluate the financial strength of our customers by reviewing the aging of their receivables, our collection experience with the customer, correspondence, financial information and third-party credit ratings. We evaluate the business climate in which our customers operate by reviewing various publicly available materials regarding our customers’ industry, including the solvency of various companies in the industry.

Inventories

Inventories consist of serialized and non-serialized parts used primarily on compression units. All inventories are stated at the lower of cost or net realizable value. Serialized parts inventories are determined using the specific identification cost method, while non-serialized parts inventories are determined using the weighted average cost method. Purchases of inventories are considered operating activities in the Consolidated Statements of Cash Flows.

Property and Equipment

Property and equipment are carried at cost except for (i) certain acquired assets which are recorded at fair value on their respective acquisition dates and (ii) impaired assets which are recorded at fair value on the last impairment evaluation date for which an adjustment was required. Overhauls and major improvements that increase the value or extend the life of compression equipment are capitalized and depreciated over three to five years. Ordinary maintenance and repairs are charged to cost of operations, exclusive of depreciation and amortization.

When property and equipment is retired or sold, its carrying value and the related accumulated depreciation are removed from our accounts and any associated gains or losses are recorded on our statements of operations in the period of sale or disposition.

Capitalized interest is calculated by multiplying our monthly effective interest rate on outstanding debt by the amount of qualifying costs, which include upfront payments to acquire certain compression units. Capitalized interest was $0.2 million, $0.2 million and $0.5 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Impairments of Long-Lived Assets

Long-lived assets with recorded values that are not expected to be recovered through future cash flows are written-down to estimated fair value. We test long-lived assets for impairment when events or circumstances indicate that the assets’ carrying value may not be recoverable or will no longer be utilized in the operating fleet. The most common circumstance requiring compression units to be evaluated for impairment is when idle units do not meet the desired performance characteristics of our active revenue generating horsepower.

The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value of the long-lived asset exceeds the sum of the undiscounted cash flows associated with the asset, an impairment loss equal to the amount of the carrying value exceeding the fair value of the asset is recognized. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units we recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use.

In the first quarter of 2020, we determined that the impairment of our goodwill was an indicator of potential impairment of the carrying amount of our long-lived assets. Accordingly, we performed a quantitative impairment test of our long-lived assets, by which we determined that they were not also impaired. No triggering events have been identified subsequent to the first quarter of 2020. Refer to Note 5 for more detailed information about impairment charges during the years ended December 31, 2021, 2020 and 2019.

Identifiable Intangible Assets

Identifiable intangible assets are recorded at cost and amortized using the straight-line method over their estimated useful lives, which is the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The estimated useful lives of our intangible assets range from 15 to 25 years.

We assess identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the first quarter of 2020, we determined that the impairment of our goodwill was an indicator of potential impairment of the carrying amount of our identifiable intangible assets. Accordingly, we performed a quantitative impairment test of our identifiable intangible assets, by which we determined that they were not also impaired. No triggering events have been identified subsequent to the first quarter of 2020.

We did not record any impairment of identifiable intangible assets for the years ended December 31, 2021, 2020 or 2019.

Goodwill

Goodwill represents consideration paid in excess of the fair value of the identifiable net assets acquired in a business combination. Goodwill is not amortized, but is reviewed for impairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwill may not be recovered.

We recorded a $619.4 million goodwill impairment for the year ended December 31, 2020, which reduced our goodwill balance to zero, and did not record any goodwill impairment during the year ended December 31, 2019. Refer to the Goodwill section in Note 5 for more information about the goodwill impairment assessment performed during the years ended December 31, 2020 and 2019.

Revenue Recognition

Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services or goods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Incidental items, if any, that are immaterial in the context of the contract are recognized as expenses. Refer to Note 12 for more detailed information about revenue recognition for the years ended December 31, 2021, 2020 and 2019.

Income Taxes

We are organized as a partnership for U.S. federal and state income tax purposes. As a result, our partners are responsible for U.S. federal and state income taxes based upon their distributive share of our items of income, gain, loss, or deduction. Texas imposes an entity-level income tax on partnerships that is based on Texas sourced taxable margin (the “Texas Margin Tax”). We have included in the consolidated financial statements a provision for Texas Margin Tax. Refer to Note 8 for more detailed information about the Texas Margin Tax for the years ended December 31, 2021, 2020 and 2019.

Pass Through Taxes

Sales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis.

Fair Value Measurements

Accounting standards on fair value measurements establish a framework for measuring fair value and stipulate disclosures about fair value measurements. The standards apply to recurring and non-recurring financial and non-financial assets and liabilities that require or permit fair value measurements. Among the required disclosures is the fair value hierarchy of inputs we use to value an asset or a liability. The three levels of the fair value hierarchy are described as follows:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date.

Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 inputs are unobservable inputs for the asset or liability.

As of December 31, 2021, our financial instruments consisted primarily of cash and cash equivalents, trade accounts receivable, trade accounts payable and long-term debt. The book values of cash and cash equivalents, trade accounts receivable,

and trade accounts payable are representative of fair value due to their short-term maturities. The carrying amount of our revolving credit facility approximates fair value due to the floating interest rates associated with the debt.

The fair value of our Senior Notes 2026 and Senior Notes 2027 were estimated using quoted prices in inactive markets and are considered Level 2 measurements.

The following table summarizes the aggregate principal amount and fair value of our Senior Notes 2026 and Senior Notes 2027 (in thousands):


	December 31,
	2021		2020
Senior Notes 2026, aggregate principal	$	725,000	$	725,000
Fair value of Senior Notes 2026	755,813		761,250

Senior Notes 2027, aggregate principal	750,000		750,000
Fair value of Senior Notes 2027	787,500		800,625

Nonrecurring Fair Value Measurements

During the first quarter of 2020 certain potential impairment indicators were identified, specifically (i) the decline in the market price of our common units, (ii) the decline in global commodity prices and (iii) the COVID-19 pandemic; which together indicated the fair value of the reporting unit was less than its carrying amount as of March 31, 2020. We performed a quantitative impairment test as of March 31, 2020 that resulted in a goodwill impairment of $619.4 million for the year ended December 31, 2020. Significant estimates used in our goodwill impairment analysis included cash flow forecasts, our estimate of the market’s weighted average cost of capital and market multiples, which are Level 3 inputs. Refer to Note 5 for further information on our goodwill impairment analysis.

Operating Segment

We operate in a single business segment, the compression services business.

Trade Accounts Receivable

The allowance for credit losses, which was $2.1 million and $5.0 million as of December 31, 2021 and 2020, respectively, is our best estimate of the amount of probable credit losses included in our existing accounts receivable.

The following summarizes activity within our trade accounts receivable allowance for credit losses balance (in thousands):

________________________

(1)On January 1, 2020, we adopted Topic 326 using the modified retrospective approach, refer to Note 2 for more information.

Improved market conditions for customers due to the recovery in commodity prices during 2021 was the primary factor contributing to the decrease to the allowance for credit losses for the year ended December 31, 2021.

The potential negative impact to our customers of low commodity prices during 2020, driven by decreased demand for and global oversupply of crude oil as a result of the COVID-19 pandemic, was the primary factor contributing to the increase to the allowance for credit losses for the year ended December 31, 2020.

During the year ended December 31, 2019, we recorded $1.1 million to the current-period provision for expected credit losses.

Depreciation is calculated using the straight-line method over the estimated useful lives of the assets as follows:


Compression equipment, acquired new			25 years
Compression equipment, acquired used			5 - 25 years
Furniture and fixtures			3 - 10 years
Vehicles and computer equipment			1 - 10 years
Buildings			5 years
Leasehold improvements			5 years

Depreciation expense on property and equipment was $209.4 million, $209.6 million and $202.0 million for the years ended December 31, 2021, 2020 and 2019, respectively.

During the years ended December 31, 2021, there was a gain on disposition of assets of $2.6 million. During the years ended December 31, 2020 and 2019, there was a loss on disposition of assets of $0.1 million and $0.9 million, respectively.

For the years ended December 31, 2021, 2020 and 2019, we evaluated the future deployment of our idle fleet under current market conditions and determined to retire 26, 37 and 33 compressor units, respectively, for a total of approximately 11,000, 15,000 and 11,000 horsepower, respectively, that were previously used to provide compression services in our business. As a result, we recorded impairments of compression equipment of $5.1 million, $8.1 million and $5.9 million for the years ended December 31, 2021, 2020 and 2019, respectively.

The primary causes for these impairments were: (i) units were not considered marketable in the foreseeable future, (ii) units were subject to excessive maintenance costs or (iii) units were unlikely to be accepted by customers due to certain performance

characteristics of the unit, such as the inability to meet current quoting criteria without excessive retrofitting costs. These compression units were written down to their respective estimated salvage values, if any.

Amortization expense for the years ended December 31, 2021, 2020 and 2019 was $29.4 million, $29.4 million and $29.4 million, respectively. The expected amortization of the intangible assets for each of the five succeeding years is $29.4 million.

Goodwill

We performed a quantitative goodwill impairment test as of March 31, 2020 and determined fair value using a weighted combination of the income approach and the market approach. Determining fair value of a reporting unit requires judgment and use of significant estimates and assumptions. Such estimates and assumptions include revenue growth rates, EBITDA margins, weighted average costs of capital and future market conditions, among others. We believe the estimates and assumptions used were reasonable and based on available market information, but variations in any of the assumptions could have resulted in materially different calculations of fair value and determinations of whether or not an impairment is indicated. Under the income approach, we determined fair value based on estimated future cash flows, including estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflects the overall level of inherent risk of the Partnership. Cash flow projections were derived from four-year operating forecasts plus an estimate of later period cash flows, all of which were developed by management. Subsequent period cash flows were developed using growth rates that management believed were reasonably likely to occur. Under the market approach, we determined fair value by applying valuation multiples of comparable publicly-traded companies to the projected EBITDA of the Partnership and then averaging that estimate with similar historical calculations using a three-year average. In addition, we estimated a reasonable control premium representing the incremental value that would accrue to us if we were to be acquired.

Based on the quantitative goodwill impairment test described above, our carrying amount exceeded fair value and as a result, we recognized a goodwill impairment of $619.4 million for the year ended December 31, 2020.

As of October 1, 2019, we performed a qualitative assessment of relevant events and circumstances potentially indicating the likelihood of goodwill impairment. The qualitative assessment included weighting such factors as (i) macroeconomic conditions, (ii) industry and market considerations, (iii) cost factors, (iv) overall financial performance of the reporting unit, (v) other relevant entity-specific events, and (vi) consideration of whether there was a sustained decrease in the price of our units. Upon completion of our qualitative assessment, we concluded that it was not more likely than not that the fair value of our single reporting unit was less than its carrying value and that our goodwill was not impaired for the year ended December 31, 2019.

Leases [Abstract]

Lease Accounting

On January 1, 2019, we adopted FASB Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC Topic 842”). ASC Topic 842 requires entities to recognize lease assets and liabilities on the balance sheet for all leases with a term of more than one year, including operating leases, which historically were not recorded on the balance sheet in accordance with the prior standard.

Lessee Accounting

We maintain both finance leases and operating leases, primarily related to office space, warehouse facilities and certain corporate equipment. Our leases have remaining lease terms of up to eight years, some of which include options that permit renewals for additional periods.

We determine if an arrangement is a lease at inception. Operating leases are included in lease right-of-use (“ROU”) assets, accrued liabilities and operating lease liabilities in our consolidated balance sheets. Finance leases are included in property and equipment, accrued liabilities and other liabilities in our consolidated balance sheets.

ROU lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU lease assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. ROU lease assets also include any lease payments made and exclude lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable costs such as our proportionate share of actual costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are recognized in the period in which they are incurred.

For short-term leases (leases that have terms of twelve months or less upon commencement), lease payments are recognized on a straight line basis and no ROU assets are recorded. For certain equipment leases, such as office equipment, we account for the lease and non-lease components as a single lease component.

Lessor Accounting

We granted a bargain purchase option to a customer with respect to certain compressor packages leased to the customer. The bargain purchase option provides the customer with an option to acquire the equipment at a value significantly less than the fair market value at the end of the lease term.

During 2021, the customer exercised its bargain purchase option resulting in a gain of $1.1 million recognized within loss (gain) on disposition of assets for the year ended December 31, 2021.

We accounted for this option as a sales type lease resulting in a current installment receivable included in other accounts receivable of $2.9 million as of December 31, 2020.

Prior to the customer exercising its bargain purchase option, revenue and interest income related to the lease was recognized over the lease term. We recognized maintenance revenue within contract operations revenue and interest income within interest expense, net. Maintenance revenue recognized for the years ended December 31, 2021, 2020 and 2019 was

$0.3 million, $1.3 million and $1.3 million, respectively. Interest income recognized for the years ended December 31, 2021, 2020 and 2019 was $0.1 million, $0.4 million and $0.7 million, respectively.

ASC Topic 842 provides lessors with a practical expedient to not separate non-lease components from the associated lease components and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under ASC Topic 606 Revenue from Contracts with Customers (“ASC Topic 606”) and certain conditions are met. Our contract operations services agreements meet these conditions and we consider the predominant component to be the non-lease components, resulting in the ongoing recognition of revenue following ASC Topic 606 guidance.

Income Tax Disclosure [Abstract]

Income Tax Expense (Benefit)

We are subject to the Texas Margin Tax, which applies a tax to our gross margin. We do not conduct business in any other state where a similar tax is applied. The Texas Margin Tax requires certain forms of legal entities, including limited partnerships, to pay a tax of 0.75% on its “margin,” as defined in the law, based on annual results. The tax base to which the tax is applied is the least of (i) 70% of total revenues for federal income tax purposes, (ii) total revenue less cost of goods sold or (iii) total revenue less compensation for federal income tax purposes.

Components of our income tax expense are as follows (in thousands):


	Year Ended December 31,

Current tax expense	$	916	$	803	$	810
Deferred tax expense (benefit)	(42)		530		1,376
Total income tax expense	$	874	$	1,333	$	2,186

Deferred income tax balances are the direct effect of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the taxes are actually paid or recovered. The tax effects of temporary differences related to property and equipment, identifiable intangible assets and goodwill that gives rise to deferred tax assets (liabilities), included net within other liabilities, are as follows (in thousands):

Deferred tax liabilities, net	$	(4,404)	$	(4,446)

FASB ASC Topic 740 Income Taxes (“Topic 740”) provides guidance on measurement and recognition in accounting for income tax uncertainties and provides related guidance on derecognition, classification, disclosure, interest, and penalties. As of December 31, 2021, we had no material unrecognized tax benefits (as defined in Topic 740). We do not expect to incur interest charges or penalties related to our tax positions, but if such charges or penalties are incurred, our policy is to account for interest charges and penalties as income tax expense in the Consolidated Statements of Operations. Our U.S. Federal income tax returns for years 2019 and 2020 are currently under examination by the Internal Revenue Service (“IRS”) and our Texas Margin Tax returns for report years 2018 through 2021 are currently under examination by the Texas Comptroller of Public Accounts.

The Bipartisan Budget Act of 2015 provides that any tax adjustments (including any applicable penalties and interest) resulting from partnership audits will generally be determined at the partnership level for tax years beginning after December 31, 2017. To the extent possible under these rules, our General Partner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a revised information statement to each unitholder and former unitholder with respect to an audited and adjusted return. The Bipartisan Budget Act of 2015 allows a partnership to elect to apply these provisions to any return of the partnership filed for partnership taxable years beginning after the date of the enactment, November 2, 2015. We do not intend to elect to apply these provisions for any tax return filed for partnership taxable years beginning before January 1, 2018.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Credit Agreement

On December 8, 2021, the Partnership amended and restated its existing credit agreement by entering into the Seventh Amended and Restated Credit Agreement (the “Credit Agreement”), by and among USA Compression Partners, LP, as borrower, the guarantors party thereto from time to time (the “Guarantors”), the lenders party thereto from time to time, and JPMorgan Chase Bank, N.A., as administrative agent and issuing bank. The Credit Agreement matures on December 8, 2026, except that if any portion of the Senior Notes 2026 are outstanding on December 31, 2025, the Credit Agreement will mature on December 31, 2025.

The Credit Agreement has an aggregate commitment of $1.6 billion (subject to availability under our borrowing base), with a further potential increase of up to $200 million. The Partnership’s obligations under the Credit Agreement are guaranteed by the Guarantors, which currently consists of all of the Partnership’s existing subsidiaries. In addition, the Partnership’s obligations under the Credit Agreement are secured by: (i) substantially all of the Partnership’s assets and substantially all of the assets of the Guarantors, excluding real property and other customary exclusions; and (ii) all of the equity interests of the Partnership’s U.S. restricted subsidiaries (subject to customary exceptions).

Borrowings under the Credit Agreement bear interest at a per annum interest rate equal to, at the Partnership’s option, either the Alternate Base Rate or SOFR plus the applicable margin. “Alternate Base Rate” means the greatest of (i) the prime rate, (ii) the applicable federal funds effective rate plus 0.50% and (iii) one-month SOFR rate plus 1.00%. The applicable margin for borrowings varies (a) in the case of SOFR loans, from 2.00% to 2.75% per annum and (b) in the case of Base Rate loans, from 1.00% to 1.75% per annum, and are determined based on a total leverage ratio pricing grid. In addition, the Borrower is required to pay commitment fees based on the daily unused amount of the Credit Agreement in an amount per annum equal to 0.375%. Amounts borrowed and repaid under the Credit Agreement may be re-borrowed, subject to borrowing base availability.

The Credit Agreement permits us to make distributions of available cash to unitholders so long as (i) no default under the facility has occurred, is continuing or would result from the distribution, (ii) immediately prior to and after giving effect to such distribution, we are in compliance with the facility’s financial covenants, and (iii) immediately prior to and after giving effect to such distribution, (a) on or before September 30, 2023, we have availability under the Credit Agreement of at least $250 million and (b) after September 30, 2023, we have availability under the Credit Agreement of at least $100 million. In addition, the Credit Agreement contains various covenants that may limit, among other things, our ability to (subject to exceptions):

•grant liens;

•make certain loans or investments;

•incur additional indebtedness or guarantee other indebtedness;

•enter into transactions with affiliates;

•merge or consolidate;

•sell our assets; and

•make certain acquisitions.

The Credit Agreement also contains various financial covenants, including covenants requiring us to maintain:

•a minimum EBITDA to interest coverage ratio of 2.5 to 1.0, determined as of the last day of each fiscal quarter, with EBITDA and interest expense annualized for the fiscal quarter most recently ended;

•a ratio of total secured indebtedness to EBITDA not greater than 3.00 to 1.00 or less than 0.00 to 1.00, determined as of the last day of each fiscal quarter, with EBITDA annualized for the fiscal quarter most recently ended; and

•a maximum funded debt to EBITDA ratio, determined as of the last day of each fiscal quarter with EBITDA annualized for the fiscal quarter most recently ended, (i) 5.75 to 1.00 through the second fiscal quarter of 2022, (ii) 5.50 to 1.00 from the third quarter of 2022 through the third quarter of 2023 and (iii) 5.25 to 1.00 thereafter. In addition, the Partnership may increase the applicable ratio by 0.25 for any fiscal quarter during which a Specified Acquisition (as defined in the Credit Agreement) occurs and the following two fiscal quarters, but in no event shall the maximum ratio exceed 5.50 to 1.00 for any fiscal quarter as a result of such increase.

If a default exists under the Credit Agreement, the lenders will be able to accelerate the maturity on the amount then outstanding and exercise other rights and remedies.

In connection with entering into the Credit Agreement, we paid certain upfront fees and arrangement fees to the arrangers, syndication agents and senior managing agents of the Credit Agreement in the amount of $10.0 million during the year ended December 31, 2021. These fees were capitalized to loan costs and are amortized over the remaining term of the Credit Agreement.

In connection with an amendment to our prior credit agreement, we incurred arrangement fees, consent fees and other fees in the amount of $3.4 million during the year ended December 31, 2020. These fees were capitalized to loan costs and are amortized over the remaining term of the credit agreement.

As of December 31, 2021, we were in compliance with all of our covenants under the Credit Agreement.

As of December 31, 2021, we had outstanding borrowings under the Credit Agreement of $516.3 million, $1.1 billion of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $261.9 million. The borrowing base consists of eligible accounts receivable, inventory and compression units. The largest component, representing 95% of the borrowing base as of December 31, 2021, was eligible compression units. Eligible compression units consist of compressor packages that are under service contracts, leased or rented and carried in the financial statements as fixed assets.

Our weighted-average interest rate in effect for all borrowings under the Credit Agreement and our prior credit agreement for the year ended December 31, 2021 was 2.98%, and our weighted-average interest rate under the Credit Agreement as of December 31, 2021 was 2.68%. There were no letters of credit issued as of December 31, 2021. We pay a commitment fee of 0.375% on the unused portion of the Credit Agreement.

The Credit Agreement is a “revolving credit facility” that includes a lock box arrangement, whereby remittances from customers are forwarded to a bank account controlled by the administrative agent and are applied to reduce borrowings under the facility. Amounts borrowed and repaid under the Credit Agreement may be re-borrowed.

Senior Notes 2027

On March 7, 2019, the Partnership and USA Compression Finance Corp. (“Finance Corp”) co-issued the Senior Notes 2027. The Senior Notes 2027 mature on September 1, 2027 and accrue interest from at the rate of 6.875% per year. Interest on the Senior Notes 2027 is payable semi-annually in arrears on each of March 1 and September 1.

At any time prior to September 1, 2022, we may redeem up to 35% of the aggregate principal amount of the Senior Notes 2027 at a redemption price equal to 106.875% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, in an amount not greater than the net proceeds from one or more equity offerings, provided that at least 65% of the aggregate principal amount of the Senior Notes 2027 remains outstanding immediately after the occurrence of such redemption (excluding Senior Notes 2027 held by us and our subsidiaries) and redemption occurs within 180 days of the date of the closing of such equity offering.

Prior to September 1, 2022, we may redeem all or a part of the Senior Notes 2027 at a redemption price equal to the sum of (i) the principal amount thereof, plus (ii) a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date.

On or after September 1, 2022, we may redeem all or a part of the Senior Notes 2027 at redemption prices (expressed as percentages of the principal amount) set forth below, plus accrued and unpaid interest, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on September 1 of the years indicated below:


Year	Percentages
2022	105.156	%
2023	103.438	%
2024	101.719	%
2025 and thereafter	100.000	%

If we experience a change of control followed by a ratings decline, unless we have previously exercised or concurrently exercise our right to redeem the Senior Notes 2027 (as described above), we may be required to offer to repurchase the Senior Notes 2027 at a purchase price equal to 101% of the principal amount repurchased, plus accrued and unpaid interest, if any, to the repurchase date.

The indenture governing the Senior Notes 2027 (the “2027 Indenture”) contains certain financial ratios that we must comply with in order to make certain restricted payments as described in the 2027 Indenture. As of December 31, 2021, we were in compliance with such financial covenants under the 2027 Indenture.

In connection with issuing the Senior Notes 2027, we incurred certain issuance costs in the amount of $13.3 million during the year ended December 31, 2019, which is amortized over the term of the Senior Notes 2027.

The Senior Notes 2027 are fully and unconditionally guaranteed (the “2027 Guarantees”), jointly and severally, on a senior unsecured basis by all of our existing subsidiaries (other than Finance Corp), and will be fully and unconditionally guaranteed, jointly and severally, by each of our future restricted subsidiaries that either borrows under, or guarantees, the Credit Agreement or guarantees certain of our other indebtedness (collectively, the “Guarantors”). The Senior Notes 2027 and the 2027 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’, Finance Corp’s, and our existing and future senior indebtedness and senior to the Guarantors’, Finance Corp’s, and our future subordinated indebtedness, if any. The Senior Notes 2027 and the 2027 Guarantees are effectively subordinated in right of payment to all of the Guarantors’, Finance Corp’s, and our existing and future secured debt, including debt under the Credit Agreement and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of our subsidiaries that do not guarantee the Senior Notes 2027.

On December 18, 2019, the Partnership closed an exchange offer whereby holders of the Senior Notes 2027 exchanged all of the Senior Notes 2027 for an equivalent amount of senior notes (“Exchange Notes 2027”) registered under the Securities Act. The Exchange Notes 2027 are substantially identical to the Senior Notes 2027, except that the Exchange Notes 2027 have been registered with the SEC and do not contain the transfer restrictions, restrictive legends, registration rights or additional interest provisions of the Senior Notes 2027.

Senior Notes 2026

On March 23, 2018, the Partnership and Finance Corp co-issued the Senior Notes 2026. The Senior Notes 2026 mature on April 1, 2026 and accrue interest from March 23, 2018 at the rate of 6.875% per year. Interest on the Senior Notes 2026 is payable semi-annually in arrears on each of April 1 and October 1.

We may redeem all or a part of the Senior Notes 2026 at redemption prices (expressed as percentages of the principal amount) set forth below, plus accrued and unpaid interest, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 of the years indicated below:


Year	Percentages
2021	105.156	%
2022	103.438	%
2023	101.719	%
2024 and thereafter	100.000	%

If we experience a change of control followed by a ratings decline, unless we have previously exercised or concurrently exercise our right to redeem the Senior Notes 2026 (as described above), we may be required to offer to repurchase the Senior

Notes 2026 at a purchase price equal to 101% of the principal amount repurchased, plus accrued and unpaid interest, if any, to the repurchase date.

The indenture governing the Senior Notes 2026 (the “2026 Indenture”) contains certain financial ratios that we must comply with in order to make certain restricted payments as described in the 2026 Indenture. As of December 31, 2021, we were in compliance with such financial covenants under the 2026 Indenture.

The Senior Notes 2026 are fully and unconditionally guaranteed (the “2026 Guarantees”), jointly and severally, on a senior unsecured basis by the Guarantors. The Senior Notes 2026 and the 2026 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’, Finance Corp’s, and our existing and future senior indebtedness and senior to the Guarantors’, Finance Corp’s, and our future subordinated indebtedness, if any. The Senior Notes 2026 and the 2026 Guarantees are effectively subordinated in right of payment to all of the Guarantors, Finance Corp’s, and our existing and future secured debt, including debt under the Credit Agreement and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of our subsidiaries that do not guarantee the Senior Notes 2026.

On January 14, 2019, the Partnership closed an exchange offer whereby holders of the Senior Notes 2026 exchanged all of the Senior Notes 2026 for an equivalent amount of senior notes (“Exchange Notes 2026”) registered under the Securities Act. The Exchange Notes 2026 are substantially identical to the Senior Notes 2026, except that the Exchange Notes 2026 have been registered with the SEC and do not contain the transfer restrictions, restrictive legends, registration rights or additional interest provisions of the Senior Notes 2026.

We have no assets or operations independent of our subsidiaries, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. Each of the Guarantors is 100% owned by us. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended (“Securities Act”).

Subsidiary Guarantors

The Partnership may from time to time file a Registration Statement on Form S-3 with the SEC to register the issuance and sale of, among other securities, debt securities, which may be co-issued by Finance Corp (together with the Partnership, the “Issuers”) and fully and unconditionally guaranteed on a joint and several basis by the Partnership’s operating subsidiaries for the benefit of each holder and the trustee. Such guarantees are expected to be subject to release, subject to certain limitations, as follows (i) upon the sale, exchange or transfer, by way of a merger or otherwise, to any person that is not our affiliate, of all of our direct or indirect limited partnership or other equity interest in such subsidiary guarantor; or (ii) upon delivery by an Issuer of a written notice to the trustee of the release or discharge of all guarantees by such subsidiary guarantor of any debt of the Issuers other than obligations arising under the indenture governing such debt and any debt securities issued under such indenture, except a discharge or release by or as a result of payment under such guarantees.

Preferred Unit and Warrant Private Placement

On April 2, 2018, we completed a private placement of $500 million in the aggregate of (i) newly authorized and established Preferred Units and (ii) warrants to purchase common units (the “Warrants”) pursuant to a Series A Preferred Unit and Warrant Purchase Agreement dated January 15, 2018, with certain investment funds managed or advised by EIG Global Energy Partners (collectively, the “Preferred Unitholders”). We issued 500,000 Preferred Units with a face value of $1,000 per Preferred Unit and issued two tranches of Warrants to the Preferred Unitholders, which included Warrants to purchase

5,000,000 common units with a strike price of $17.03 per unit and 10,000,000 common units with a strike price of $19.59 per unit.

On November 13, 2018, the Partnership filed a Registration Statement on Form S-3 to register 41,202,553 common units that are potentially issuable upon conversion of the Preferred Units and exercise of the Warrants.

The Preferred Units rank senior to the common units with respect to distributions and rights upon liquidation. The Preferred Unitholders are entitled to receive cumulative quarterly cash distributions equal to $24.375 per Preferred Unit.

As of December 31, 2021 and 2020, 500,000 Preferred Units were issued and outstanding.

We have declared and paid quarterly cash distributions per unit to our Preferred Unitholders of record as follows:


Payment date	Distribution per Preferred Unit
February 8, 2019	$	24.375
May 10, 2019	24.375

Announced Quarterly Distribution

On January 13, 2022, we declared a cash distribution of $24.375 per unit on our Preferred Units. The distribution was paid on February 4, 2022 to unitholders of record as of the close of business on January 24, 2022.

Redemption and Conversion Features

The Preferred Units are convertible, at the option of the holder, into common units in accordance with the terms of our Second Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”) as follows: one third on or after April 2, 2021, two thirds on or after April 2, 2022, and 100% are convertible on or after April 2, 2023. The conversion rate for the Preferred Units is the quotient of (a) the sum of (i) $1,000, plus (ii) any unpaid cash distributions on the applicable Preferred Unit, divided by (b) $20.0115 for each Preferred Unit. The Preferred Unitholders are entitled to vote on an as-converted basis with the common unitholders and (as proportionately adjusted for unit splits, unit distributions and similar transactions) will have certain other class voting rights with respect to any amendment to the Partnership Agreement that would adversely affect any rights, preferences or privileges of the Preferred Units. In addition, upon certain events involving a change of control the Preferred Unitholders may elect, among other potential elections, to convert their Preferred Units to common units at the then change of control conversion rate.

On or after April 2, 2023, we have the option to redeem all or any portion of the Preferred Units then outstanding, subject to certain minimum redemption threshold amounts, for a redemption price set forth in the Partnership Agreement. On or after April 2, 2028, each Preferred Unitholder will have the right to require us to redeem all or a portion of their Preferred Units, subject to certain minimum redemption threshold amounts, for a redemption price set forth in the Partnership Agreement, which we may elect to pay up to 50% in common units, subject to certain additional limits. The Preferred Units are presented as

temporary equity in the mezzanine section of the consolidated balance sheets because the redemption provisions on or after April 2, 2028 are outside the Partnership’s control.

The Preferred Units were recorded at their issuance date fair value, net of issuance cost. Net income allocations increase the carrying value and declared distributions decrease the carrying value of the Preferred Units. As the Preferred Units are not currently redeemable and it is not probable that they will become redeemable, adjustment to the initial carrying value is not necessary and would only be required if it becomes probable that the Preferred Units would become redeemable.

Changes in the Preferred Units balance are summarized below (in thousands):

Class B Units Conversion

On July 30, 2019, 6,397,965 Class B Units representing limited partner interests in us (“Class B Units”) automatically converted into common units on a one-for-one basis, resulting in the issuance of 6,397,965 common units to Energy Transfer.

Announced Quarterly Distribution

On January 13, 2022, we announced a cash distribution of $0.525 per unit on our common units. The distribution was paid on February 4, 2022 to unitholders of record as of the close of business on January 24, 2022.

DRIP

During the years ended December 31, 2021, 2020 and 2019, distributions of $1.8 million, $1.9 million and $1.0 million, respectively, were reinvested under the DRIP resulting in the issuance of 118,399, 188,695 and 60,584 common units, respectively.

On August 5, 2020, we filed a registration statement on Form S-3 for the issuance of up to 5,000,000 units under the DRIP.

Warrants

As of December 31, 2021 and December 31, 2020, we had two tranches of warrants outstanding, which includes warrants to purchase (i) 5,000,000 common units with a strike price of $17.03 per common unit and (ii) 10,000,000 common units with a strike price of $19.59 per common unit. The Warrants may be exercised by the holders at any time before April 2, 2028.

The Warrants are presented within the equity section of the Consolidated Balance Sheets in accordance with GAAP as they are indexed to the Partnership’s own stock and require physical settlement or net share settlement. The Warrants were valued at issuance using the Black-Scholes-Merton model.

Loss Per Unit

The computations of loss per unit are based on the weighted average number of participating securities outstanding during the period. Basic loss per unit is determined by dividing net income (loss) allocated to participating securities after deducting the amount distributed on Preferred Units, by the weighted average number of participating securities outstanding during the period. Net loss attributable to unitholders is allocated to participating securities based on their respective shares of the distributed and undistributed earnings for the period. To the extent cash distributions exceed net loss attributable to unitholders for the period, the excess distributions are allocated to all participating securities outstanding based on their respective ownership percentages. Diluted earnings per unit are computed using the treasury stock method, which considers the potential issuance of limited partner units associated with our long-term incentive plan and warrants. The classes of participating securities include common units, Class B Units prior to July 30, 2019, and certain equity-based compensation awards. Unvested phantom units and unexercised warrants are not included in basic earnings per unit, as they are not considered to be participating securities, but are included in the calculation of diluted earnings per unit to the extent that they are dilutive, and in the case of warrants to the extent they are considered “in the money”.

For the years ended December 31, 2021, 2020 and 2019, approximately 829,000, 634,000 and 290,000 incremental unvested phantom units, respectively, were excluded from the calculation of diluted earnings per unit because the impact was anti-dilutive. Our outstanding warrants are not applicable to the computation as they are not considered “in the money” for the years ended December 31, 2021, 2020 or 2019.

Contract operations revenue

Revenue from contracted compression, station, gas treating and maintenance services is recognized ratably under our fixed-fee contracts over the term of the contract as services are provided to our customers. Initial contract terms typically range from six months to five years, however we usually continue to provide compression services at a specific location beyond the initial contract term, either through contract renewal or on a month-to-month or longer basis. We primarily enter into fixed-fee

contracts whereby our customers are required to pay our monthly fee even during periods of limited or disrupted throughput. Services are generally billed monthly, one month in advance of the commencement of the service month, except for certain customers who are billed at the beginning of the service month, and payment is generally due 30 days after receipt of our invoice. Amounts invoiced in advance are recorded as deferred revenue until earned, at which time they are recognized as revenue. The amount of consideration we receive and revenue we recognize is based upon the fixed fee rate stated in each service contract.

Variable consideration exists in select contracts when billing rates vary based on actual equipment availability or volume of total installed horsepower.

Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenues to each performance obligation based on its relative standalone service fee. We generally determine standalone service fees based on the service fees charged to customers or use expected cost plus margin.

The majority of our service performance obligations are satisfied over time as services are rendered at selected customer locations on a monthly basis and based upon specific performance criteria identified in the applicable contract. The monthly service for each location is substantially the same service month to month and is promised consecutively over the service contract term. We measure progress and performance of the service consistently using a straight-line, time-based method as each month passes, because our performance obligations are satisfied evenly over the contract term as the customer simultaneously receives and consumes the benefits provided by our service. If variable consideration exists, it is allocated to the distinct monthly service within the series to which such variable consideration relates. We have elected to apply the invoicing practical expedient to recognize revenue for such variable consideration, as the invoice corresponds directly to the value transferred to the customer based on our performance completed to date.

There are typically no material obligations for returns or refunds. Our standard contracts do not usually include material non-cash consideration.

Retail parts and services revenue

Retail parts and services revenue is earned primarily on freight and crane charges that are directly reimbursable by our customers and maintenance work on units at our customers’ locations that are outside the scope of our core maintenance activities. Revenue from retail parts and services is recognized at the point in time the part is transferred or service is provided and control is transferred to the customer. At such time, the customer has the ability to direct the use of the benefits of such part or service after we have performed our services. We bill upon completion of the service or transfer of the parts, and payment is generally due 30 days after receipt of our invoice. The amount of consideration we receive and revenue we recognize is based upon the invoice amount. There are typically no material obligations for returns, refunds, or warranties. Our standard contracts do not usually include material variable or non-cash consideration.

Contract Assets

We record contract assets when we have completed performance under a contract but our right to consideration is not yet unconditional. We had no contract assets as of December 31, 2021 or 2020.

Deferred Revenue

We record deferred revenue when cash payments are received or due in advance of our performance. Components of deferred revenue were as follows:


		December 31,
	Balance sheet location	2021		2020
Current (1)	Deferred revenue	$	51,216	$	47,202
Noncurrent	Other liabilities	4,823		8,200
Total		$	56,039	$	55,402

________________________

(1)We recognized $43.2 million of revenue during the year ended December 31, 2021 related to our deferred revenue balance as of December 31, 2020.

Performance Obligations

As of December 31, 2021, the aggregate amount of transaction price allocated to unsatisfied performance obligations related to our contract operations revenue is $438.6 million. We expect to recognize these remaining performance obligations as follows (in thousands):


	2022		2023		2024		2025		Thereafter		Total
Remaining performance obligations	$	277,919	$	109,206	$	39,375	$	10,089	$	2,026	$	438,615

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Transactions with Related Parties

We provide compression services to entities affiliated with Energy Transfer, which as of December 31, 2021, owned approximately 47% of our limited partner interests and 100% of the General Partner.

The following table summarizes the revenues from Energy Transfer on our consolidated statement of operations (in thousands):


	Year Ended December 31,
	2021		2020		2019
Related party revenues	$	11,967	$	12,372	$	19,967

We had approximately $18,000 and $120,000 within related party receivables on our consolidated balance sheets as of December 31, 2021 and December 31, 2020, respectively, from such affiliated Energy Transfer entities. Additionally, the Partnership had a $44.9 million related party receivable from Energy Transfer as of December 31, 2021 and December 31, 2020 related to indemnification for sales tax contingencies. See Note 16 for more information related to such sales tax contingencies.

Pursuant to that certain Board Representation Agreement entered into by us, the General Partner, Energy Transfer LP and EIG in connection with our private placement of Preferred Units and Warrants to EIG, EIG Management Company, LLC has the right to designate one of the members of the Board for so long as the holders of the Preferred Units hold more than 5% of the Partnership’s outstanding common units in the aggregate (taking into account the common units that would be issuable upon conversion of the Preferred Units and exercise of the Warrants).

Unit-based Compensation

12 Months Ended

Dec. 31, 2021

Share-based Payment Arrangement [Abstract]

Unit-based Compensation

Unit-Based Compensation

Long-Term Incentive Plan

In January 2013, the board of directors of the General Partner (the “Board”) adopted the USA Compression Partners, LP 2013 Long-Term Incentive Plan (as amended, the “LTIP”), which is available for certain employees, consultants and directors of the General Partner and any of its affiliates who perform services for us. The LTIP provides for awards of unit options, unit appreciation rights, restricted units, phantom units, DERs, unit awards, profits interest units and other unit-based awards. Under the LTIP, the maximum number of common units available for issuance is 10,000,000 and the term of the LTIP is until November 1, 2028. Awards that are forfeited, canceled, paid or otherwise terminate or expire without the actual delivery of common units will be available for delivery pursuant to other awards. The LTIP is administered by the Board or a committee thereof.

The General Partner’s executive officers, certain of its employees and certain of its independent directors were granted these awards to incentivize them to help drive our future success and to share in the economic benefits of that success. All employees with phantom units have a portion of their award settled in cash and a portion settled in common units upon vesting, unless otherwise approved by the Board. The amount that can be settled in cash is in excess of the employee’s minimum statutory tax-withholding rate. ASC Topic 718, Compensation – Stock Compensation, requires the entire amount of an award with such features to be accounted for as a liability. Under the liability method of accounting for unit-based compensation, we re-measure the fair value of the award at each financial statement date until the award vests or is forfeited. The fair value is measured using the market price of the Partnership’s common units. During the requisite service period (the vesting period of the awards), compensation cost is recognized using the proportionate amount of the award’s fair value that has been earned through service to date. Phantom units granted to independent directors do not have a cash settlement option and as such we account for these awards as equity. Each phantom unit is granted in tandem with a corresponding DER, which entitles the recipient to receive an amount in cash on a quarterly basis equal to the product of (i) the number of the recipient’s outstanding, unvested phantom units on the record date for such quarter and (ii) the quarterly distribution declared by the Board for such quarter with respect to the Partnership’s common units.

During the years ended December 31, 2021, 2020 and 2019, an aggregate of 638,903, 741,963 and 717,869, respectively, phantom units (including the corresponding DERs) were granted under the LTIP to the General Partner’s executive officers and certain of its employees and independent directors. The phantom units (including the corresponding DERs) awarded are subject to restrictions on transferability, customary forfeiture provisions and time vesting provisions. Phantom unit awards granted after July 30, 2018 vest incrementally, with 60% of the phantom units vesting on December 5 of the third year following the grant and the remaining 40% vesting on December 5 of the fifth year following the grant. Phantom unit awards that were granted to employees of USAC Management prior to July 30, 2018 vested evenly over a three-year service period.

Phantom units granted on or after July 30, 2018 vest in full upon a change in control. Award recipients do not have all the rights of a unitholder in the Partnership with respect to the phantom units until the units have vested.

As of December 31, 2021 and 2020, our total unit-based compensation liability was $13.3 million and $9.2 million, respectively. During the years ended December 31, 2021, 2020 and 2019, we recognized $15.5 million, $8.4 million and $10.8 million of compensation expense associated with these awards, respectively, recorded in selling, general and administrative expense. During the years ended December 31, 2021, 2020 and 2019, amounts paid related to the cash settlement of vested awards under the LTIP were $3.2 million, $1.1 million and $1.7 million, respectively.

The total fair value and intrinsic value of the phantom units vested under the LTIP was $4.0 million, $1.7 million and $4.6 million for the years ended December 31, 2021, 2020 and 2019, respectively.

The following table summarizes information regarding phantom unit awards for the periods presented:


	Number of Units	Weighted-Average Grant Date Fair Value per Unit
Phantom units outstanding at December 31, 2018	1,431,064	$	14.98
Granted	717,869	15.88
Vested	(301,329)	13.06
Forfeited	(45,620)	16.78
Phantom units outstanding at December 31, 2019	1,801,984	$	15.09
Granted	741,963	12.55
Vested	(223,658)	17.27
Forfeited	(182,332)	15.36
Phantom units outstanding at December 31, 2020	2,137,957	$	14.88
Granted	638,903	14.92
Vested	(475,831)	15.13
Forfeited	(71,261)	14.50
Phantom units outstanding at December 31, 2021	2,229,768	$	13.57

The unrecognized compensation cost associated with phantom unit awards was an aggregate $25.2 million as of December 31, 2021. We expect to recognize the unrecognized compensation cost for these awards on a weighted-average basis over a period of 2.7 years.

Commitments and Contingencies	Dec. 31, 2021
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies (a)Major Customers We did not have revenue from any single customer representing 10% or more of total revenue for the years ended December 31, 2021, 2020 or 2019. As of December 31, 2021, one customer accounted for 14% of our trade account receivables, net balance. As of December 31, 2020, two customers accounted for 13% and 11% of our trade accounts receivables, net balance, respectively. (b)Litigation From time to time, we and our subsidiaries may be involved in various claims and litigation arising in the ordinary course of business. In management’s opinion, the resolution of such matters is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. (c)Equipment Purchase Commitments Our future capital commitments are comprised of binding commitments under purchase orders for new compression units ordered but not received. The commitments as of December 31, 2021 were $19.3 million, all of which is expected to be settled within the next twelve months. (d)Sales Tax Contingencies Our compliance with state and local sales tax regulations is subject to audit by various taxing authorities. Certain taxing authorities have either claimed or issued an assessment that specific operational processes, which we and others in our industry regularly conduct, result in transactions that are subject to state sales taxes. We and others in our industry have disputed these claims and assessments based on either existing tax statutes or published guidance by the taxing authorities. We are currently protesting certain assessments made by the Oklahoma Tax Commission (“OTC”). We believe it is reasonably possible that we could incur losses related to this assessment depending on whether the administrative law judge assigned by the OTC accepts our position that the transactions are not taxable and we ultimately lose any and all subsequent legal challenges to such determination. We estimate that the range of losses we could incur is from $0 to approximately $19.5 million, including penalty and interest. As of December 31, 2021 and 2020, we have recorded a $44.9 million accrued liability and $44.9 million related party receivable from Energy Transfer related to open audits with the Office of the Texas Comptroller of Public Accounts (the “Comptroller”), wherein the Comptroller has challenged the applicability of the manufacturing exemption. (e)Environmental The Partnership’s operations are subject to federal, state and local laws and rules and regulations regarding water quality, hazardous and solid waste management, air quality control and other environmental matters. These laws, rules and regulations require the Partnership to conduct its operations in a specified manner and to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections and other approvals. Failure to comply with applicable environmental laws, rules and regulations may expose the Partnership to significant fines, penalties and/or interruptions in operations. The Partnership’s environmental policies and procedures are designed to achieve compliance with such applicable laws and regulations. These evolving laws and regulations and claims for damages to property, employees, other persons and the environment resulting from current or past operations may result in significant expenditures and liabilities in the future.

Basis of Presentation and Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and the accompanying results. Although these estimates are based on management’s available knowledge of current and expected future events, actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of 90 days or less to be cash equivalents.
Trade Accounts Receivable and Allowance for Credit Losses	Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount. Allowance for Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (“Topic 326”): Measurement of Credit Losses on Financial Instruments. On January 1, 2020, we adopted Topic 326 using the modified retrospective approach, which was effective for interim and annual reporting periods beginning on or after December 15, 2019. Topic 326 requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. To adopt Topic 326, we evaluated our allowance for credit losses related to our two financial assets measured at amortized cost: (i) trade accounts receivable and (ii) net investment in lease related to our sales-type lease discussed further in Note 7. Due to the short-term nature of our trade accounts receivable, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. There was no cumulative effect adjustment to partners’ capital upon adoption. Our determination of the allowance for credit losses requires us to make estimates and judgments regarding our customers’ ability to pay amounts due. We continuously evaluate the financial strength of our customers and the overall business climate in which our customers operate, and make adjustments to the allowance for credit losses as necessary. We evaluate the financial strength of our customers by reviewing the aging of their receivables, our collection experience with the customer, correspondence, financial information and third-party credit ratings. We evaluate the business climate in which our customers operate by reviewing various publicly available materials regarding our customers’ industry, including the solvency of various companies in the industry.
Inventories	InventoriesInventories consist of serialized and non-serialized parts used primarily on compression units. All inventories are stated at the lower of cost or net realizable value. Serialized parts inventories are determined using the specific identification cost method, while non-serialized parts inventories are determined using the weighted average cost method. Purchases of inventories are considered operating activities in the Consolidated Statements of Cash Flows.
Property and Equipment	Property and Equipment Property and equipment are carried at cost except for (i) certain acquired assets which are recorded at fair value on their respective acquisition dates and (ii) impaired assets which are recorded at fair value on the last impairment evaluation date for which an adjustment was required. Overhauls and major improvements that increase the value or extend the life of compression equipment are capitalized and depreciated over three to five years. Ordinary maintenance and repairs are charged to cost of operations, exclusive of depreciation and amortization. When property and equipment is retired or sold, its carrying value and the related accumulated depreciation are removed from our accounts and any associated gains or losses are recorded on our statements of operations in the period of sale or disposition. Capitalized interest is calculated by multiplying our monthly effective interest rate on outstanding debt by the amount of qualifying costs, which include upfront payments to acquire certain compression units. Capitalized interest was $0.2 million, $0.2 million and $0.5 million for the years ended December 31, 2021, 2020 and 2019, respectively.
Impairments of Long-Lived Assets	Impairments of Long-Lived Assets Long-lived assets with recorded values that are not expected to be recovered through future cash flows are written-down to estimated fair value. We test long-lived assets for impairment when events or circumstances indicate that the assets’ carrying value may not be recoverable or will no longer be utilized in the operating fleet. The most common circumstance requiring compression units to be evaluated for impairment is when idle units do not meet the desired performance characteristics of our active revenue generating horsepower. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value of the long-lived asset exceeds the sum of the undiscounted cash flows associated with the asset, an impairment loss equal to the amount of the carrying value exceeding the fair value of the asset is recognized. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units we recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use. In the first quarter of 2020, we determined that the impairment of our goodwill was an indicator of potential impairment of the carrying amount of our long-lived assets. Accordingly, we performed a quantitative impairment test of our long-lived assets, by which we determined that they were not also impaired. No triggering events have been identified subsequent to the first quarter of 2020. Refer to Note 5 for more detailed information about impairment charges during the years ended December 31, 2021, 2020 and 2019.
Identifiable Intangible Assets	Identifiable Intangible Assets Identifiable intangible assets are recorded at cost and amortized using the straight-line method over their estimated useful lives, which is the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The estimated useful lives of our intangible assets range from 15 to 25 years. We assess identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the first quarter of 2020, we determined that the impairment of our goodwill was an indicator of potential impairment of the carrying amount of our identifiable intangible assets. Accordingly, we performed a quantitative impairment test of our identifiable intangible assets, by which we determined that they were not also impaired. No triggering events have been identified subsequent to the first quarter of 2020. We did not record any impairment of identifiable intangible assets for the years ended December 31, 2021, 2020 or 2019.
Goodwill	Goodwill Goodwill represents consideration paid in excess of the fair value of the identifiable net assets acquired in a business combination. Goodwill is not amortized, but is reviewed for impairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwill may not be recovered. We recorded a $619.4 million goodwill impairment for the year ended December 31, 2020, which reduced our goodwill balance to zero, and did not record any goodwill impairment during the year ended December 31, 2019. Refer to the Goodwill section in Note 5 for more information about the goodwill impairment assessment performed during the years ended December 31, 2020 and 2019.
Revenue Recognition	Revenue Recognition Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services or goods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Incidental items, if any, that are immaterial in the context of the contract are recognized as expenses. Refer to Note 12 for more detailed information about revenue recognition for the years ended December 31, 2021, 2020 and 2019.
Income Taxes	Income Taxes We are organized as a partnership for U.S. federal and state income tax purposes. As a result, our partners are responsible for U.S. federal and state income taxes based upon their distributive share of our items of income, gain, loss, or deduction. Texas imposes an entity-level income tax on partnerships that is based on Texas sourced taxable margin (the “Texas Margin Tax”). We have included in the consolidated financial statements a provision for Texas Margin Tax. Refer to Note 8 for more detailed information about the Texas Margin Tax for the years ended December 31, 2021, 2020 and 2019.
Pass Through Taxes	Pass Through Taxes Sales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis.
Fair Value Measurements	Fair Value Measurements Accounting standards on fair value measurements establish a framework for measuring fair value and stipulate disclosures about fair value measurements. The standards apply to recurring and non-recurring financial and non-financial assets and liabilities that require or permit fair value measurements. Among the required disclosures is the fair value hierarchy of inputs we use to value an asset or a liability. The three levels of the fair value hierarchy are described as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. As of December 31, 2021, our financial instruments consisted primarily of cash and cash equivalents, trade accounts receivable, trade accounts payable and long-term debt. The book values of cash and cash equivalents, trade accounts receivable, and trade accounts payable are representative of fair value due to their short-term maturities. The carrying amount of our revolving credit facility approximates fair value due to the floating interest rates associated with the debt. The fair value of our Senior Notes 2026 and Senior Notes 2027 were estimated using quoted prices in inactive markets and are considered Level 2 measurements. Nonrecurring Fair Value Measurements During the first quarter of 2020 certain potential impairment indicators were identified, specifically (i) the decline in the market price of our common units, (ii) the decline in global commodity prices and (iii) the COVID-19 pandemic; which together indicated the fair value of the reporting unit was less than its carrying amount as of March 31, 2020. We performed a quantitative impairment test as of March 31, 2020 that resulted in a goodwill impairment of $619.4 million for the year ended December 31, 2020. Significant estimates used in our goodwill impairment analysis included cash flow forecasts, our estimate of the market’s weighted average cost of capital and market multiples, which are Level 3 inputs. Refer to Note 5 for further information on our goodwill impairment analysis.
Operating Segment	Operating Segment We operate in a single business segment, the compression services business.
Recent Accounting Pronouncements	Recent Accounting PronouncementsIn August 2020, FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 changes how entities account for convertible instruments and contracts in an entity’s own equity, as well as updates guidance on earnings per unit and other related disclosures. The amendments in this update are effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020. We adopted this new standard on January 1, 2022. The impact on our disclosures is not material and there was no impact to our consolidated financial statements.
