NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(1) Organization and Description of Business
Unless otherwise indicated, the terms “our,” “we,” “us,” “the Partnership” and similar language refer to USA Compression Partners, LP, collectively with its consolidated operating 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 ETO.
The accompanying unaudited condensed consolidated financial statements include the accounts of the Partnership and its operating subsidiaries, all of which are wholly-owned by us.
(2) Basis of Presentation and Summary of Significant Accounting Policies
Basis of Presentation
Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP and pursuant to the rules and regulations of the SEC.
In the opinion of our management, such financial information reflects all normal recurring adjustments necessary for a fair presentation of these interim unaudited condensed consolidated financial statements in accordance with GAAP. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements contained in our annual report on Form 10-K for the year ended December 31, 2019 filed on February 18, 2020 (our “2019 Annual Report”).
Use of Estimates
Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP, which includes the use of estimates and assumptions by management that affect the reported amounts of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities that existed at the date of the unaudited condensed consolidated financial statements. Although these estimates were based on management’s available knowledge of current and expected future events, actual results could differ from these estimates.
Significant 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 and do not bear interest.
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.
5

Table of Contents
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 and is the same process for both of our financial assets as they have similar risk characteristics. We continuously evaluate the financial strength of our customers based on collection experience, the overall business climate in which our customers operate and specific identification of customer credit losses and make adjustments to the allowance 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.
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 on the unaudited condensed 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 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 $0.1 million and $0.2 million for the three and six months ended June 30, 2020, respectively, and $0.2 million and $0.4 million for the three and six months ended June 30, 2019, respectively.
Impairment 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.
Refer to Note 5 for more detailed information about impairment charges during the three and six months ended June 30, 2020 and 2019.

Table of Contents
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.
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.
Refer to Note 5 for more detailed information about goodwill impairment charges during the six months ended June 30, 2020.
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.
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 unaudited condensed consolidated financial statements a provision for the Texas Margin Tax.
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 June 30, 2020, 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.

(3) Trade Accounts Receivable
The allowance for credit losses, which was $5.4 million and $2.5 million as of June 30, 2020 and December 31, 2019, 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)The provision for expected credit losses recognized during the three months ended June 30, 2020 was $2.2 million.
Low crude oil prices, driven by decreased demand for and global oversupply of crude oil as a result of the COVID-19 pandemic, is the primary factor contributing to the increase to the allowance for credit losses for the three and six months ended June 30, 2020. We cannot predict the duration of these conditions or the severity of their impact on our customers and the collectability of their accounts receivable.

As of June 30, 2020 and December 31, 2019, there was $15.7 million and $11.4 million, respectively, of property and equipment purchases in accounts payable and accrued liabilities.
On a quarterly basis, we evaluate the future deployment of our idle fleet under current market conditions. For the three and six months ended June 30, 2020, we determined to retire 11 compressor units, for a total of approximately 5,100 horsepower, that were previously used to provide compression services in our business. As a result, we recorded an impairment of compression equipment of $3.9 million for the three and six months ended June 30, 2020.
For the six months ended June 30, 2019, we determined to retire 14 compressor units, for a total of approximately 4,700 horsepower, that were previously used to provide compression services in our business. As a result, we recorded an impairment of compression equipment of $3.2 million for the six months ended June 30, 2019.
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.
No impairment was recorded for the three months ended June 30, 2019.

Accumulated amortization of intangible assets was $202.2 million and $187.5 million as of June 30, 2020 and December 31, 2019, respectively. The expected amortization of the intangible assets for each of the five succeeding years is $29.4 million.
Goodwill
During the first quarter of 2020 certain potential impairment indicators were identified, specifically (i) the decline in the market price of our common units, (ii) the decline in global commodity prices and (iii) the COVID-19 pandemic; which together indicated the fair value of the reporting unit was less than its carrying amount as of March 31, 2020.
We performed a quantitative goodwill impairment test as of March 31, 2020 and determined fair value using a weighted combination of the income approach and the market approach. Determining fair value of a reporting unit requires judgment and use of significant estimates and assumptions. Such estimates and assumptions include revenue growth rates, EBITDA margins, weighted average costs of capital and future market conditions, among others. We believe the estimates and assumptions used were reasonable and based on available market information, but variations in any of the assumptions could have resulted in materially different calculations of fair value and determinations of whether or not an impairment is indicated. Under the income approach, we determined fair value based on estimated future cash flows, including estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflects the overall level of inherent risk of the Partnership. Cash flow projections were derived from four-year operating forecasts plus an estimate of later period cash flows, all of which were developed by management. Subsequent period cash flows were developed using growth rates that management believed were reasonably likely to occur. Under the market approach, we determined fair value by applying valuation multiples of comparable publicly-traded companies to the projected EBITDA of the Partnership and then averaging that estimate with similar historical calculations using a three-year average. In addition, we estimated a reasonable control premium representing the incremental value that would accrue to us if we were to be acquired.
Based on the quantitative goodwill impairment test described above, our carrying amount exceeded fair value and as a result, we recognized a goodwill impairment of $619.4 million for the three months ended March 31, 2020.

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 ten years, some of which include options that permit renewals for additional periods.

Table of Contents
We determine if an arrangement is a lease at inception. Operating leases are included in lease right-of-use assets, accrued liabilities and operating lease liabilities in our unaudited condensed consolidated balance sheets. Finance leases are included in property and equipment, accrued liabilities and other liabilities in our unaudited condensed consolidated balance sheets.
Right-of-use (“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 in 2021.
We accounted for this option as a sales-type lease resulting in a current installment receivable included in other accounts receivable of $3.2 million and $4.0 million, and a long-term installment receivable included in other assets of $1.7 million and $2.9 million as of June 30, 2020 and December 31, 2019, respectively.
As of June 30, 2020, there is no allowance for credit losses on our net investment in the sales-type lease based on our collections experience with the customer.
Revenue and interest income related to the lease is recognized over the lease term. We recognize maintenance revenue within contract operations revenue and interest income within interest expense, net. Maintenance revenue and interest income were as follows (in thousands):

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.

Revolving Credit Facility
As of June 30, 2020, we were in compliance with all of our covenants under the Credit Agreement. 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, which we expect to maintain for the term.
As of June 30, 2020, we had outstanding borrowings under the Credit Agreement of $447.8 million, $1.2 billion of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $151.1 million. Our weighted average interest rate in effect for all borrowings under the Credit Agreement as of June 30, 2020 was 2.77%, with a weighted average interest rate of 3.60% for the six months ended June 30, 2020. There were no letters of credit issued as of June 30, 2020. We pay a commitment fee of 0.375% on the unused portion of the Credit Agreement.
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 after giving effect to such distribution, we have availability under the Credit Agreement of at least $100 million.
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, for the annualized trailing three months; and
a maximum funded debt to EBITDA ratio of 5.0 to 1.0, determined as of the last day of each fiscal quarter, for the annualized trailing three months, subject to a provision for increases to such threshold by 0.5 in connection with certain future acquisitions for the six consecutive month period following the period in which any such acquisition occurs.
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.
On August 3, 2020 (the “Amendment Effective Date”), we amended the Credit Agreement to, among other items, increase the maximum funded debt to EBITDA ratio to (i) 5.75 to 1.00 for the fiscal quarters ending September 30, 2020 and December 31, 2020, (ii) 5.50 to 1.00 for the fiscal quarters ending March 31, 2021 and June 30, 2021 and (iii) 5.25 to 1.00 for the fiscal quarters ending September 30, 2021 and December 31, 2021 (reverting back to 5.00 to 1.00 for each fiscal quarter thereafter). In addition, the amendment provides that the 0.5 increase in maximum funded debt to EBITDA ratio applicable to certain future acquisitions (for the six consecutive month period in which any such acquisition occurs) is only available beginning with the fiscal quarter ending September 30, 2021, and in any case shall not increase the maximum funded debt to EBITDA ratio above 5.50 to 1.00.
The amendment also provides that, from the Amendment Effective Date until the last day of the fiscal quarter ending December 31, 2021 (the “Covenant Relief Period”), the availability requirement in order to make restricted payments from capital contributions and from available cash are each increased from $100 million to $250 million and the availability requirement in order to make prepayments of our senior notes, any subordinated indebtedness or any other indebtedness for borrowed money is increased from $100 million to $250 million. In addition, during the Covenant Relief Period, the applicable margin for Eurodollar borrowings is increased from a range of 2.00% – 2.75% to a range of 2.25% – 3.00%. The amendment further provides that the Partnership becomes guarantor of the obligations of all other guarantors under the Credit Agreement.

The Senior Notes 2026 accrue interest 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 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 June 30, 2020, 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 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 2026 and the 2026 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’ and our existing and future senior indebtedness and senior to the Guarantors’ 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’ 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.
Senior Notes 2027
On March 7, 2019, the Partnership and Finance Corp co-issued 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.
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 June 30, 2020, we were in compliance with such financial covenants under the 2027 Indenture.
The Senior Notes 2027 are fully and unconditionally guaranteed (the “2027 Guarantees”), jointly and severally, on a senior unsecured basis by 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’ and our existing and future senior indebtedness and senior to the Guarantors’ 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’ 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.
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.

Announced Quarterly Distribution
On July 21, 2020, we announced a cash distribution of $0.525 per unit on our common units. The distribution will be paid on August 10, 2020 to common unitholders of record as of the close of business on July 31, 2020.
DRIP
During the six months ended June 30, 2020, distributions of $0.9 million were reinvested under the DRIP resulting in the issuance of 96,592 common units.
Warrants
As of June 30, 2020 and December 31, 2019, 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 (collectively, the “Warrants”). The Warrants may be exercised by the holders at any time before April 2, 2028.
Earnings (Loss) per Unit
The computation of earnings per unit is based on the weighted average number of participating securities outstanding during the applicable period. Basic earnings per unit is determined by dividing net income (loss) allocated to participating securities after deducting the distributions 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 they are dilutive, and in the case of Warrants to the extent they are considered “in the money.”
For the three and six months ended June 30, 2020, approximately 551,000 and 520,000 incremental unvested phantom units, respectively, were excluded from the calculation of diluted earnings per common unit because the impact was anti-dilutive and our outstanding Warrants are not included in the computation as they are not considered “in the money” for either period.
For the three months ended June 30, 2019, approximately 172,000 incremental unvested phantom units and 40,000 incremental warrants represent the difference between our basic and diluted weighted average common units outstanding. For the six months ended June 30, 2019, approximately 86,000 incremental unvested phantom units and 20,000 incremental warrants were excluded from the calculation of diluted earnings per common unit because the impact was anti-dilutive.

Additionally, the Partnership had a $44.9 million related party receivable from ETO as of June 30, 2020 and December 31, 2019 related to indemnification for sales tax contingencies incurred by the USA Compression Predecessor. See Note 13 for more information related to such sales tax contingencies.
(13) Commitments and Contingencies​
(a)Major Customers​
We did not have revenue from any single customer representing 10% or more of total revenue for the three and six months ended June 30, 2020 or 2019.
(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 and serialized parts ordered but not received. Those commitments as of June 30, 2020 were $18.3 million, which we expect to settle during the remainder of 2020.
(d)Sales Tax Contingencies
Our compliance with state and local sales tax regulations is subject to audit by various taxing authorities. The Office of the Texas Comptroller of Public Accounts (“Comptroller”) has claimed 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 other companies in our industry have disputed these claims based on existing tax statutes which provide for manufacturing exemptions on the transactions in question. The manufacturing exemptions are based on the fact that our natural gas compression equipment is used in the process of preparing natural gas for ultimate use and sale.
As of June 30, 2020, we have recorded a $44.9 million accrued liability and $44.9 million related party receivable from ETO related to open audits with the Comptroller.
During January 2020, we entered into a compromise and settlement agreement with the Comptroller for the audit of the USA Compression Predecessor for the period from August 2006 to December 2007 for $4.0 million, which was paid by the USA Compression Predecessor’s former owner in February 2020.
For more information, see Note 17 to the consolidated financial statements included in our 2019 Annual Report.
(14) Recent Accounting Pronouncements
In March 2019, FASB issued ASU 2020-04, Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendment to Topic 848 provides relief from certain contract modification accounting requirements for the transition away from LIBOR and certain other reference rates. Adoption of the amendments in this update are optional, effective upon issuance and may be adopted during any interim or annual period through December 31, 2022. We are currently evaluating the impact, if any, of the amendments to Topic 848 on our consolidated financial statements.

Table of Contents
(15) Subsequent Event
On the Amendment Effective Date, we amended the Credit Agreement to, among other items, increase the maximum funded debt to EBITDA ratio to (i) 5.75 to 1.00 for the fiscal quarters ending September 30, 2020 and December 31, 2020, (ii) 5.50 to 1.00 for the fiscal quarters ending March 31, 2021 and June 30, 2021 and (iii) 5.25 to 1.00 for the fiscal quarters ending September 30, 2021 and December 31, 2021 (reverting back to 5.00 to 1.00 for each fiscal quarter thereafter). In addition, the amendment provides that the 0.5 increase in maximum funded debt to EBITDA ratio applicable to certain future acquisitions (for the six consecutive month period in which any such acquisition occurs) is only available beginning with the fiscal quarter ending September 30, 2021, and in any case shall not increase the maximum funded debt to EBITDA ratio above 5.50 to 1.00.
The amendment also provides that during the Covenant Relief Period the availability requirement in order to make restricted payments from capital contributions and from available cash are each increased from $100 million to $250 million and the availability requirement in order to make prepayments of our senior notes, any subordinated indebtedness or any other indebtedness for borrowed money is increased from $100 million to $250 million. In addition, during the Covenant Relief Period, the applicable margin for Eurodollar borrowings is increased from a range of 2.00% – 2.75% to a range of 2.25% – 3.00%. The amendment further provides that the Partnership becomes guarantor of the obligations of all other guarantors under the Credit Agreement.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS
This report contains “forward-looking statements.” All statements other than statements of historical fact contained in this report are forward-looking statements, including, without limitation, statements regarding our plans, strategies, prospects and expectations concerning our business, results of operations and financial condition. You can identify many of these statements by looking for words such as “believe,” “expect,” “intend,” “project,” “anticipate,” “estimate,” “continue,” “if,” “outlook,” “will,” “could,” “should,” or similar words or the negatives thereof.
Known material factors that could cause our actual results to differ from those in these forward-looking statements are described in Part I, Item IA “Risk Factors” of our 2019 Annual Report, Part II, Item 1A “Risk Factors” of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, as well as our subsequent filings with the SEC. Important factors that could cause our actual results to differ materially from the expectations reflected in these forward-looking statements include, among other things:
changes in the long-term supply of and demand for crude oil and natural gas, including as a result of uncertainty regarding the length of time it will take for the United States and the rest of the world to slow the spread of COVID-19 to the point where applicable authorities are comfortable continuing to ease, or declining to reinstate certain restrictions on various commercial and economic activities; such restrictions are designed to protect public health but also have the effect of significantly reducing demand for crude oil and natural gas;
the severity and duration of world health events, including the recent COVID-19 outbreak, related economic repercussions, actions taken by governmental authorities and other third parties in response to the pandemic and the resulting severe disruption in the oil and gas industry and negative impact on demand for oil and gas, which continues to negatively impact our business;
changes in general economic conditions and changes in economic conditions of the crude oil and natural gas industries specifically, including the ability of members of the Organization of the Petroleum Exporting Countries (“OPEC”) and Russia (together with OPEC and other allied producing countries, “OPEC+”) to agree on and comply with supply limitations;
uncertainty regarding the timing, pace and extent of an economic recovery in the United States and elsewhere, which in turn will likely affect demand for crude oil and natural gas and therefore the demand for the compression and treating services we provide and the commercial opportunities available to us;
the deterioration of the financial condition of our customers, which may result in the initiation of bankruptcy proceedings with respect to customers;
renegotiation of material terms of customer contracts;
competitive conditions in our industry;
our ability to realize the anticipated benefits of acquisitions;
actions taken by our customers, competitors and third-party operators;
changes in the availability and cost of capital;
operating hazards, natural disasters, epidemics, pandemics (such as COVID-19), weather-related delays, casualty losses and other matters beyond our control;
operational challenges relating to the COVID-19 pandemic and efforts to mitigate the spread of the virus, including logistical challenges, protecting the health and well-being of our employees, remote work arrangements, performance of contracts and supply chain disruptions;
the effects of existing and future laws and governmental regulations; and
the effects of future litigation.
Many of the foregoing risks and uncertainties are, and will be, exacerbated by the COVID-19 pandemic and any consequent worsening of the global business and economic environment. New factors emerge from time to time, and it is not possible for us to predict all such factors. Should one or more of the risks or uncertainties described in this Quarterly Report occur, or should underlying assumptions prove incorrect, actual results and plans could differ materially from those expressed in any forward-looking statements.

Except as required by law, we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

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 production of natural gas and crude oil. As such, we have focused our activities in areas of attractive natural gas and crude oil production growth, which are generally found in these shale and unconventional resource plays. According to studies promulgated by the Energy Information Agency, the production and transportation volumes in these shale plays are expected to increase over the long term due to the comparatively attractive economic returns as compared to returns achieved in many conventional basins. Furthermore, the changes in production volumes and pressures of shale plays over time require a wider range of compression services than in conventional basins. We believe we are well-positioned to meet these changing operating conditions due to the operational design flexibility inherent in our compression units.
A significant amount of our assets are utilized in natural gas infrastructure applications typically located in shale plays, primarily in centralized gathering systems and processing facilities utilizing large horsepower compression units. Given the infrastructure nature of these applications and long-term investment horizon of our customers, we have generally experienced stability in service rates and higher sustained utilization relative to other businesses more directly tied to drilling activity and wellhead economics. In addition to our natural gas infrastructure applications, a portion of our fleet is used in connection with gas lift applications on crude oil production targeted by horizontal drilling techniques and can be accomplished by both small and large horsepower compression equipment.
Domestic natural gas production generally occurs in either primarily gas basins, such as the Marcellus, Utica and Haynesville Shales, or in basins such as the Permian and Delaware Basins and the Mid-Continent, where associated gas volumes are a byproduct of crude oil production. Over the past several years, relative stability in commodity prices has encouraged investment in domestic exploration and production (“E&P”) and midstream infrastructure across the energy industry, particularly in the low-cost basins characterized by associated gas and crude oil production. The development of these basins producing both commodities has created additional incremental demand for natural gas compression over the last several years as it is a critical method to transport associated gas volumes or enhance crude oil production through gas lift, allowing our customers to produce additional crude oil at more economically attractive levels.
However, recent events have impacted and may continue to impact our operations in areas driven by associated gas and crude oil production. The considerable crude oil price drop in March 2020 due to the collapse of discussions among members of OPEC+, Saudi Arabia’s announcement that it would be discounting its price, and increasing its supply, of crude oil into the global market and the ongoing global impact, both real and perceived, on crude oil demand from the COVID-19 pandemic has created additional uncertainty regarding the demand for compression services in certain of our operating areas. While our business is focused on providing compression services and does not have any direct exposure to commodity prices, we have indirect exposure to commodity prices as overall levels of activity across the energy industry are influenced by the commodity price environment. For example, despite the quick rebound in crude oil prices during the second quarter of 2020, drilling activity expectations have not materially changed as many E&P companies, including some of our customers, maintained their reduced capital expenditure forecasts from the first quarter of 2020 for the remainder of 2020. We expect the resulting decrease in new production to in turn negatively affect the demand for new compression services and potentially reduce the need for us to spend capital on new compression units for deployment in associated gas producing regions. The impact on existing production of crude oil and natural gas, however, is far less certain. Variables such as takeaway capacity, flaring considerations, potential production prorationing, reservoir pressure and flow rates, high switching costs associated with large horsepower compressors (borne by our customers), and specific company dynamics may all factor into producers’ decisions with respect to their existing production. For example, as wells age, and the reservoir pressures naturally continue to decline, more horsepower may be required to meet the customer’s operational needs. In contrast, small horsepower gas lift applications have historically been more susceptible to commodity price swings, and we have experienced, and may continue to experience, some pressure on service rates and utilization in small horsepower gas lift applications. We cannot predict with reasonable certainty the effect on utilization of our assets servicing existing production in these regions.
Unlike crude oil, natural gas production and prices have been influenced by different drivers over the recent past, as there is no OPEC+ equivalent in the global natural gas market and therefore the price of natural gas is generally determined by market forces of supply and demand rather than by a centralized market coordinator. Over the past several years, increased gas

production in the U.S. driven by large volumes of gas produced from shale sources has been a main driver of an overall drop in natural gas prices. This sustained low natural gas price environment has helped create relatively resilient baseload demand for natural gas for domestic use in power generation and for industrial purposes such as chemical plants and other types of manufacturing. Also, the development of long-term export infrastructure has continued to occur alongside the low natural gas price environment, and the U.S. became a net exporter of natural gas into global markets in 2017. We expect this baseload natural gas demand will continue to drive long-term domestic natural gas production despite low natural gas prices.
In addition to the relatively stable supply, demand and price fundamentals of natural gas, we believe that the geographic diversity and portability of our assets should help mitigate the impact of current market volatility. While we expect that the reduction in the production of associated gas and demand for our services in certain regions that began in the first quarter of 2020 will continue for the remainder of 2020, we remain optimistic that such reduction in production will have a positive impact on both natural gas prices and the utilization of our assets in other regions primarily tied to natural gas prospects, such as the Marcellus, Utica and Haynesville Shales. Given that these are primarily gas shales, we believe it is reasonable to expect that these areas could see additional capital inflows to take advantage of relatively more attractive economics and offset the reduced supply of associated natural gas in other regions, which could increase demand for our services in these shales. Should such demand increase exceed our current compression capability in these shales, the design flexibility of our compression units making them capable of rapid reconfiguration and deployment would allow us to meet such demand by relocating units to these areas. On the whole, we believe the longer-term outlook for natural gas fundamentals remains positive, as market signs point to a more balanced gas market toward the end of 2020 and into 2021.
In summary, the outlook for commodity prices is mixed and could have a varying impact on our business. Whereas several factors, including uncertain future demand, have recently caused severe volatility in crude oil prices, on the natural gas side, relatively more moderate demand destruction coupled with anticipated associated gas production decreases have somewhat counterbalanced softness in pricing and expectations of full gas storage going into the fall, thereby providing some support to natural gas futures prices. The overall outlook for our compression services will depend, in part, on the timing and extent of recovery in the commodity markets, and we believe the potential for natural gas to recover more quickly than crude oil should help support our business activities and overall utilization and pricing.
While we anticipate that current and projected commodity prices and the related impact to activity levels in both the upstream and midstream sectors will impact our business, we cannot predict the ultimate magnitude of that impact and expect it to be varied across our operations, depending on the region, customer, nature of compression application, contract term and other factors. We believe our customers’ mid- to long-term expectations regarding commodity prices and the cost they would incur to return our large horsepower equipment will provide an incentive for our customers to keep it in the field following expiration of the primary term, whereas we believe there is likely to be greater pressure on utilization and pricing with respect to our smaller horsepower equipment.
Ultimately, the extent to which our business will be impacted by recent market developments depends on the factors described above as well as future developments beyond our control, which are highly uncertain and cannot be predicted. In response to these market events and uncertainties, in the first quarter of this year we cut our already reduced 2020 growth capital spending budget by 25% and reduced operating expenses by 10%; and we are prepared to cut spending further should the need arise. While current market volatility makes the near-term unpredictable, we believe that overall the long-term demand for our compression services will continue given the necessity of compression in facilitating the transportation and processing of natural gas as well as the production of crude oil, although we cannot predict any possible changes in such demand with reasonable certainty.
COVID-19 Update
Beginning in the first quarter of 2020, the COVID-19 pandemic prompted several states and municipalities in which we operate to take extraordinary and wide-ranging actions to contain and combat the outbreak and spread of the virus, including mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations. While many states have begun to recover from the COVID-19 pandemic and states have largely reopened their economies to varying extents, in several states the COVID-19 outbreak is worsening, and a reinstatement of severe restrictions may occur in these states. For as long as COVID-19 continues or worsens, governments may impose additional similar restrictions or reinstate previously lifted ones. To date, our field operations have continued largely uninterrupted as the U.S. Department of Homeland Security designated our industry part of our country’s critical infrastructure. Thus far, remote work and other COVID-19 related conditions have not significantly impacted our ability to maintain operations or caused us to incur significant additional expenses; however, we are unable to predict the duration or ultimate impact of current and potential future COVID-19 mitigation measures.

(1)Fleet horsepower is horsepower for compression units that have been delivered to us (and excludes units on order). As of June 30, 2020, we had approximately 18,000 horsepower on order, all of which we expect to be delivered during the remainder of 2020.
(2)Total available horsepower is revenue generating horsepower under contract for which we are billing a customer, horsepower in our fleet that is under contract but is not yet generating revenue, horsepower not yet in our fleet that is under contract but not yet generating revenue and that is subject to a purchase order, and idle horsepower. Total available horsepower excludes new horsepower on order for which we do not have an executed compression services contract.​
(3)Revenue generating horsepower is horsepower under contract for which we are billing a customer.​
(4)Calculated as the average of the month-end revenue generating horsepower for each of the months in the period.​
(5)Calculated as the average of the result of dividing the contractual monthly rate for all units at the end of each month in the period by the sum of the revenue generating horsepower at the end of each month in the period.​
(6)Calculated as the average of the month-end revenue generating horsepower per revenue generating compression unit for each of the months in the period.​
(7)Horsepower utilization is calculated as (i) the sum of (a) revenue generating horsepower, (b) horsepower in our fleet that is under contract but is not yet generating revenue, and (c) horsepower not yet in our fleet that is under contract but not yet generating revenue and that is subject to a purchase order, divided by (ii) total available horsepower less idle horsepower that is under repair. Horsepower utilization based on revenue generating horsepower and fleet horsepower as of June 30, 2020 and 2019 was 84.1% and 89.1%, 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 on revenue generating horsepower and fleet horsepower for the three months ended June 30, 2020 and 2019 was 86.0% and 89.9%, respectively. Average horsepower utilization based on revenue generating horsepower and fleet horsepower for the six months ended June 30, 2020 and 2019 was 87.9% and 90.3%, respectively.
The 1.7% increase in fleet horsepower as of June 30, 2020 compared to June 30, 2019 was attributable to compression units added to our fleet to meet then expected incremental demand by new and current customers for our compression services. The 4.1% decrease in revenue generating horsepower as of June 30, 2020 compared to June 30, 2019 was primarily due to returns of compression units from our customers, which also caused a 6.9% decrease in revenue generating compression units over the same period, partially offset by a 3.2% increase in average horsepower per revenue generating compression unit due to the organic growth in our large horsepower fleet.
The 1.1% and 1.9% increases in average revenue per revenue generating horsepower per month during the three and six months ended June 30, 2020 compared to the three and six months ended June 30, 2019, respectively, were both primarily due to contracts on new compression units and selective price increases on the existing fleet.
Average horsepower utilization decreased to 88.0% during the three months ended June 30, 2020 compared to 94.6% during the three months ended June 30, 2019. The 7.0% decrease in average horsepower utilization is primarily due to (1) a

6.2% increase in our average idle fleet from compression units returned to us and (2) a 3.9% decrease in horsepower that is on-contract or pending-contract but not yet active. Average horsepower utilization decreased to 90.2% during the six months ended June 30, 2020 compared to 94.4% during the six months ended June 30, 2019. The 4.4% decrease in average horsepower utilization is primarily due to (1) a 3.8% increase in our average idle fleet from compression units returned to us and (2) a 3.1% decrease in horsepower that is on-contract or pending-contract but not yet active. We believe the decreases in average horsepower utilization are due to a decrease in demand for compression services driven by a decline in U.S. crude oil and natural gas activity.
Average horsepower utilization based on revenue generating horsepower and fleet horsepower decreased to 86.0% and 87.9% during the three and six months ended June 30, 2020, respectively, compared to 89.9% and 90.3% during the three and six months ended June 30, 2019, respectively. The 4.3% and 2.7% decreases in average horsepower utilization based on revenue generating horsepower during the three and six months ended June 30, 2020, respectively, were both primarily attributable to an increase in our average idle fleet from compression units returned to us. We believe the decreases in average horsepower utilization based on revenue generating horsepower and fleet horsepower are due to a decrease in demand for compression services driven by a decline in U.S. crude oil and natural gas activity.

from the average revenue per revenue generating horsepower per month associated with our compression services provided under contracts in their primary term during the period.
Parts and service revenue. The $1.7 million decrease in parts and service revenue for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily attributable to a reduction in maintenance work performed on units at our customers’ locations that are outside the scope of our core maintenance activities and offered as a courtesy to our customers, and freight and crane charges that are directly reimbursable by customers. Demand for retail parts and services fluctuates from period to period based on the varying needs of our customers.
Related party revenue. Related party revenue was earned through related party transactions in the ordinary course of business with various affiliated entities of ETO. The $3.4 million decrease in related party revenue for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was attributable to a decrease in parts and service revenue, as well as a decrease in contract operations revenue due to the expiration of contracts with various affiliated entities of ETO.
Cost of operations, exclusive of depreciation and amortization. The $6.3 million decrease in cost of operations, exclusive of depreciation and amortization, for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily due to (1) a $5.2 million decrease in direct expenses, such as parts and fluids expenses, (2) a $2.5 million decrease in direct labor expenses, (3) a $1.2 million decrease in retail parts and services expenses, which have a corresponding decrease in parts and service revenue, and (4) a $1.1 million decrease in expenses related to our vehicle fleet. The decreases in parts, fluids, direct labor and vehicle expenses are primarily driven by the decrease in average revenue generating horsepower and reduced headcount during the current period. The decreases were offset by (5) a $4.6 million increase in ad valorem tax expense, due primarily to refunds received during the prior period.
Depreciation and amortization expense. The $3.6 million increase in depreciation and amortization expense for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily related to compression units placed in service to meet then expected incremental demand for our compression services by new and current customers.
Selling, general and administrative expense. The $4.1 million increase in selling, general and administrative expense for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily due to (1) a $1.9 million increase in the provision for expected credit losses, (2) a $1.9 million increase in severance charges and (3) a $1.9 million increase in unit-based compensation expense. These increases were partially offset by (4) a $0.9 million decrease in employee-related expenses and (5) a $0.5 million decrease in transaction-related expenses.
The change to the provision for expected credit losses is related to low crude oil prices driven by decreased demand due to the COVID-19 pandemic and the global oversupply of crude oil during the current period. The increase in severance charges is primarily related to the departure of one of our executives during the current period. The increase in unit-based compensation expense is primarily due to the increase in our unit price as of June 30, 2020 as compared to March 31, 2020, and the related mark-to-market change to our unit-based compensation liability. The decrease in employee-related expenses is primarily due to reduced headcount during the current period.
Impairment of compression equipment. The $3.9 million impairment of compression equipment for the three months ended June 30, 2020 was primarily the result of our evaluations of the future deployment of our idle fleet under current market conditions. Our evaluations determined that due to certain performance characteristics of the impaired equipment, such as excessive maintenance costs and the inability of the equipment to meet current emissions standards without excessive retrofitting costs, this equipment was unlikely to be accepted by customers under current market conditions.
As a result of our evaluations during the three months ended June 30, 2020, we determined to retire 11 compressor units, for a total of approximately 5,100 horsepower, that were previously used to provide compression services in our business. No impairment was recorded for the three months ended June 30, 2019.
Interest expense, net. The $0.9 million decrease in interest expense, net for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was attributable to lower weighted average interest rates under the Credit Agreement, offset by increased borrowings under the Credit Agreement.
The weighted average interest rate applicable to borrowings under the Credit Agreement was 3.09% and 5.05% for the three months ended June 30, 2020 and 2019, respectively, and average outstanding borrowings under the Credit Agreement were $455.6 million and $355.4 million for the three months ended June 30, 2020 and 2019, respectively.

Contract operations revenue. The $8.9 million increase in contract operations revenue for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to a 1.9% increase in average revenue per revenue generating horsepower per month which increased to $16.84 for the six months ended June 30, 2020 compared to $16.53 for the six months ended June 30, 2019, partially offset by a 0.6% decrease in average revenue generating horsepower due to a decrease in demand for compression services driven by a decline in U.S. crude oil and natural gas activity. Our contract operations revenue was not materially impacted by any renegotiations of our contracts with our customers, and average revenue per revenue generating horsepower per month associated with our compression services provided on a month-to-month basis did not significantly differ from the average revenue per revenue generating horsepower per month associated with our compression services provided under contracts in their primary term during the period.
Parts and service revenue. The $1.3 million decrease in parts and service revenue for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to a reduction in maintenance work performed on units at our customers’ locations that are outside the scope of our core maintenance activities and offered as a courtesy to our customers, and freight and crane charges that are directly reimbursable by customers. Demand for retail parts and services fluctuates from period to period based on the varying needs of our customers.
Related party revenue. Related party revenue was earned through related party transactions in the ordinary course of business with various affiliated entities of ETO. The $4.3 million decrease in related party revenue for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was attributable to a decrease in parts and service revenue, as well as a decrease in contract operations revenue due to the expiration of contracts with various affiliated entities of ETO.
Cost of operations, exclusive of depreciation and amortization. The $4.1 million decrease in cost of operations, exclusive of depreciation and amortization, for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily due to (1) a $3.6 million decrease in direct expenses, such as parts and fluids expenses, (2) a $2.0 million decrease in
27

Table of Contents
direct labor expenses, (3) a $1.6 million decrease in expenses related to our vehicle fleet and (4) a $1.4 million decrease in retail parts and services expenses, which have a corresponding decrease in parts and service revenue. The decreases in parts, fluids, direct labor and vehicle expenses are primarily driven by the decrease in average revenue generating horsepower and reduced headcount during the current period. The decreases were partially offset by (5) a $5.0 million increase in ad valorem tax expense, due primarily to refunds received during the prior period.
Depreciation and amortization expense. The $3.4 million increase in depreciation and amortization expense for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily related to compression units placed in service to meet then expected incremental demand for our compression services by new and current customers.
Selling, general and administrative expense. The $0.5 million increase in selling, general and administrative expense for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily due to (1) a $3.4 million increase in the provision for expected credit losses and (2) a $2.0 million increase in severance charges. These increases were offset by (3) a $3.1 million decrease in unit-based compensation expense, (4) a $0.7 million decrease in third-party professional fees, (5) a $0.6 million decrease in employee-related expenses and (6) a $0.6 million decrease in transaction-related expenses.
The change to the provision for expected credit losses is related to low crude oil prices driven by decreased demand due to the COVID-19 pandemic and the global oversupply of crude oil during the current period. The increase in severance charges is primarily related to the departure of one of our executives during the current period. The decrease in unit-based compensation expense is primarily due to the decrease in our unit price in the current period and the related mark-to-market change to our unit-based compensation liability. The decreases in employee-related expenses and professional fees are related to reduced headcount and cost savings, respectively.
Impairment of compression equipment. The $3.9 million and $3.2 million impairments of compression equipment for the six months ended June 30, 2020 and June 30, 2019, respectively, were primarily the result of our evaluations of the future deployment of our idle fleet under current market conditions. Our evaluations determined that due to certain performance characteristics of the impaired equipment, such as excessive maintenance costs and the inability of the equipment to meet current emissions standards without excessive retrofitting costs, this equipment was unlikely to be accepted by customers under current market conditions.
As a result of our evaluations during the six months ended June 30, 2020 and June 30, 2019, we determined to retire 11 and 14 compressor units, respectively, for a total of approximately 5,100 and 4,700 horsepower, respectively, that were previously used to provide compression services in our business.
Impairment of goodwill. During the first quarter of 2020 certain potential impairment indicators were identified, specifically (i) the decline in the market price of our common units, (ii) the decline in global commodity prices, and (iii) the COVID-19 pandemic; which together indicated the fair value of the reporting unit was less than its carrying amount as of March 31, 2020. Management determined fair value using a weighted combination of the income approach and the market approach and, as a result, recognized a $619.4 million impairment of goodwill for the six months ended June 30, 2020. No impairment was recorded for the six months ended June 30, 2019.
Interest expense, net. The $2.8 million increase in interest expense, net for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to a full six months of interest expense incurred in the current period on the Senior Notes 2027 issued in March 2019, which were used to reduce borrowings under the Credit Agreement, partially offset by reduced borrowings and lower weighted average interest rates under the Credit Agreement.
The weighted average interest rate applicable to borrowings under the Credit Agreement was 3.60% and 5.06% for the six months ended June 30, 2020 and 2019, respectively, and average outstanding borrowings under the Credit Agreement were $434.4 million and $610.1 million for the six months ended June 30, 2020 and 2019, respectively.

Gross margin. The $2.3 million decrease in gross margin for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was due to (1) a $5.0 million decrease in revenues and (2) a $3.6 million increase in depreciation and amortization, offset by (3) a $6.3 million decrease in cost of operations, exclusive of depreciation and amortization.
The $4.0 million increase in gross margin for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was due to (1) a $4.1 million decrease in cost of operations, exclusive of depreciation and amortization and (2) a $3.2 million increase in revenues, offset by (3) a $3.4 million increase in depreciation and amortization.
Adjusted gross margin. The $1.3 million increase in Adjusted gross margin for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was due to a $6.3 million decrease in cost of operations, exclusive of depreciation and amortization, offset by a $5.0 million decrease in revenues.
The $7.4 million increase in Adjusted gross margin for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was due to a $4.1 million decrease in cost of operations, exclusive of depreciation and amortization, and a $3.2 million increase in revenues.
Adjusted EBITDA. The $0.8 million, or 0.7%, increase in Adjusted EBITDA for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily attributable to a $1.3 million increase in Adjusted gross margin, partially offset by a $0.9 million increase in selling, general and administrative expenses, excluding unit-based compensation expense, severance charges and transaction expenses.
The $5.6 million, or 2.7%, increase in Adjusted EBITDA for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to a $7.4 million increase in Adjusted gross margin, partially offset by a $2.2 million increase in selling, general and administrative expenses, excluding unit-based compensation expense, severance charges and transaction expenses.
DCF. The $4.6 million, or 8.6%, increase in DCF for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily attributable to (1) a $3.5 million decrease in maintenance capital expenditures, (2) a $1.3 million increase in Adjusted gross margin and (3) a $0.8 million decrease in cash interest expense, net. These changes were partially offset by (4) a $0.9 million increase in selling, general and administrative expenses, excluding unit-based compensation expense, severance charges and transaction expenses.
The $4.5 million, or 4.1%, increase in DCF for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to (1) a $7.4 million increase in Adjusted gross margin and (2) a $1.6 million decrease

in maintenance capital expenditures. These changes were partially offset by (3) a $2.5 million increase in cash interest expense, net, and (4) a $2.2 million increase in selling, general and administrative expenses, excluding unit-based compensation expense, severance charges and transaction expenses.
Coverage Ratios. The increase in DCF Coverage Ratio and Cash Coverage Ratio for the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily attributable to the increase in DCF, offset by an increase in cash distributions paid on common units in the current period due to the conversion of 6,397,965 Class B Units, which did not participate in distributions, to common units on a one-for-one basis on July 30, 2019.
The decrease in DCF Coverage Ratio and Cash Coverage Ratio for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to an increase in cash distributions paid on common units in the current period due to the conversion of 6,397,965 Class B Units, which did not participate in distributions, to common units on a one-for-one basis on July 30, 2019, offset by an increase in DCF.
Liquidity and Capital Resources​
Overview
We operate in a capital-intensive industry, and our primary liquidity needs are to finance the purchase of additional compression units and make other capital expenditures, 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 common units under the DRIP.
We typically utilize cash generated by operating activities and, where necessary, borrowings under the Credit Agreement to service our debt, fund working capital, fund our estimated expansion capital expenditures, fund our maintenance capital expenditures and pay distributions to our unitholders. In response to current market conditions, we have reduced our capital spending and operating expenses through the remainder of 2020. However, if market conditions related to COVID-19 and the global oversupply of crude oil persist, this could eventually reduce our cash generated by operating activities and increase our leverage. Covenants in the Credit Agreement and other debt instruments require that we maintain certain leverage ratios, and if we predict that we may violate those covenants in the future we could: (i) delay discretionary capital spending and further reduce operating expenses; (ii) request an amendment to the Credit Agreement; or (iii) reduce or suspend distributions to our unitholders.
On August 3, 2020 (the “Amendment Effective Date”), we amended the Credit Agreement to, among other items, increase the maximum leverage ratio beginning with the fiscal quarter ending September 30, 2020 and ending with the fiscal quarter ending December 31, 2021 and provide for relief from certain covenants until December 31, 2021. Please see “Revolving Credit Facility” below for additional information regarding the amendment.
Because we distribute all of our available cash, which excludes prudent operating reserves, we expect to fund any future expansion capital expenditures or acquisitions primarily with capital from external financing sources, such as borrowings under the Credit Agreement and issuances of debt and equity securities, including under the DRIP.
Capital Expenditures
The compression services business is capital intensive, requiring significant investment to maintain, expand and upgrade existing operations. Our capital requirements 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, to replace partially or fully depreciated assets, or other capital expenditures that are incurred in maintaining our existing business and related operating income; and
expansion capital expenditures, which are capital expenditures made to expand the operating capacity or operating income capacity of assets, including by acquisition of compression units or through modification of existing compression units to increase their capacity, or to replace certain partially or fully depreciated 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 capital expenditure requirements will continue to increase as the overall size and age of our fleet increases. Our aggregate maintenance capital expenditures for the six months ended June 30, 2020 and 2019 were $13.2 million and $14.8 million, respectively. We currently plan to spend approximately $30.0 million in maintenance capital expenditures for the year 2020, including parts consumed from inventory.

Table of Contents
Without giving effect to any equipment we may acquire pursuant to any future acquisitions, we currently have budgeted between $80.0 million and $90.0 million in expansion capital expenditures for the year 2020. Our expansion capital expenditures for the six months ended June 30, 2020 and 2019 were $69.3 million and $84.0 million, respectively.
As of June 30, 2020, we had binding commitments to purchase $18.3 million of additional compression units and serialized parts, all of which we expect to be delivered during the remainder of 2020.
Cash Flows
The following table summarizes our sources and uses of cash for the six months ended June 30, 2020 and 2019 (in thousands):​
Six Months Ended June 30,
20202019
Net cash provided by operating activities$147,432  $147,586  
Net cash used in investing activities(63,796) (75,949) 
Net cash used in financing activities(83,644) (71,734) 
Net cash provided by operating activities. The $0.2 million decrease in net cash provided by operating activities for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to a $4.5 million increase in net income, as adjusted for non-cash items, offset by changes in working capital.
Net cash used in investing activities. The $12.2 million decrease in net cash used in investing activities for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to (1) a $20.4 million decrease in capital expenditures, for purchases of new compression units, related equipment and reconfiguration costs, offset by (2) a $6.6 million decrease in proceeds from disposition of property and equipment and (3) a $1.7 million decrease in proceeds from insurance recovery.
Net cash used in financing activities. The $11.9 million increase in net cash used in financing activities for the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily attributable to (1) an $18.7 million decrease in net borrowings and (2) a $7.0 million increase in cash distributions paid on common units primarily due to the conversion of 6,397,965 Class B Units, which did not participate in distributions, to common units on a one-for-one basis on July 30, 2019. These changes were partially offset by a decrease in financing costs of $13.2 million due to the issuance of the Senior Notes 2027 in March 2019.
Revolving Credit Facility​
As of June 30, 2020, we were in compliance with all of our covenants under the Credit Agreement. As of June 30, 2020, we had outstanding borrowings under the Credit Agreement of $447.8 million, $1.2 billion of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $151.1 million.
As of July 30, 2020, we had outstanding borrowings under the Credit Agreement of $436.0 million.
On the Amendment Effective Date, we amended the Credit Agreement to, among other items, increase the maximum funded debt to EBITDA ratio to (i) 5.75 to 1.00 for the fiscal quarters ending September 30, 2020 and December 31, 2020, (ii) 5.50 to 1.00 for the fiscal quarters ending March 31, 2021 and June 30, 2021 and (iii) 5.25 to 1.00 for the fiscal quarters ending September 30, 2021 and December 31, 2021 (reverting back to 5.00 to 1.00 for each fiscal quarter thereafter). In addition, the amendment provides that the 0.5 increase in maximum funded debt to EBITDA ratio applicable to certain future acquisitions (for the six consecutive month period in which any such acquisition occurs) is only available beginning with the fiscal quarter ending September 30, 2021, and in any case shall not increase the maximum funded debt to EBITDA ratio above 5.50 to 1.00.
The amendment also provides that, from the Amendment Effective Date until the last day of the fiscal quarter ending December 31, 2021 (the “Covenant Relief Period”), the availability requirement in order to make restricted payments from capital contributions and from available cash are each increased from $100 million to $250 million and the availability requirement in order to make prepayments of our senior notes, any subordinated indebtedness or any other indebtedness for borrowed money is increased from $100 million to $250 million. In addition, during the Covenant Relief Period, the applicable margin for Eurodollar borrowings is increased from a range of 2.00% – 2.75% to a range of 2.25% – 3.00%. The amendment further provides that the Partnership becomes guarantor of the obligations of all other guarantors under the Credit Agreement.

Senior Notes
As of June 30, 2020, we had $725.0 million and $750.0 million outstanding on our Senior Notes 2026 and Senior Notes 2027, respectively.
The Senior Notes 2026 are due on April 1, 2026 and accrue interest 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 are due on September 1, 2027 and accrue interest 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.

DRIP
During the six months ended June 30, 2020, distributions of $0.9 million were reinvested under the DRIP resulting in the issuance of 96,592 common units. Such distributions are treated as non-cash transactions in the accompanying unaudited condensed consolidated statements of cash flows included under Part I, Item 1 “Financial Statements” of this report.
Non-GAAP Financial Measures​
Adjusted Gross Margin​
Adjusted gross margin is a non-GAAP financial measure. We define Adjusted gross margin as revenue less cost of operations, exclusive of depreciation and amortization expense. We believe that Adjusted gross margin is useful as a supplemental measure to investors of our operating profitability. Adjusted gross margin is impacted primarily by the pricing trends for service operations and cost of operations, including labor rates for service technicians, volume and per unit costs for lubricant oils, quantity and pricing of routine preventative maintenance on compression units and property tax rates on compression units. Adjusted gross margin should not be considered an alternative to, or more meaningful than, gross margin or any other measure of financial performance presented in accordance with GAAP. Moreover, Adjusted gross margin as presented may not be comparable to similarly titled measures of other companies. Because we capitalize assets, depreciation and amortization of equipment is a necessary element of our costs. To compensate for the limitations of Adjusted gross margin as a measure of our performance, we believe that it is important to consider gross margin determined under GAAP, as well as Adjusted gross margin, to evaluate our operating profitability.
The following table reconciles Adjusted gross margin to gross margin, its most directly comparable GAAP financial measure, for each of the periods presented (in thousands):

Adjusted EBITDA
We define EBITDA as net income (loss) before net interest expense, depreciation and amortization expense, and income tax expense. We define Adjusted EBITDA as EBITDA plus impairment of compression equipment, impairment of goodwill, interest income on capital lease, unit-based compensation expense, severance charges, certain transaction fees, loss (gain) on disposition of assets and other. We view Adjusted EBITDA as one of management’s primary tools 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 the prior month, year-to-date, prior year and budget. Adjusted EBITDA is used as a supplemental financial measure by our management and external users of our financial 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 our assets;
the viability of capital expenditure projects and the overall rates of return on alternative investment opportunities;
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 capital structure.
We believe that Adjusted EBITDA provides useful information to investors because, when viewed with our GAAP results and the accompanying reconciliations, it may provide a more complete understanding of our performance than GAAP results alone. We also believe that external users of our financial statements 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 operating activities 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 acquiring compression equipment are also necessary elements of our costs. Unit-based compensation expense related to equity awards to employees is also a necessary component of our business. Therefore, measures that exclude these elements have material limitations. To compensate for these limitations, we believe that it is important to consider both net income (loss) and net cash provided by operating activities determined under GAAP, as well as Adjusted EBITDA, to evaluate our financial performance and our liquidity. Our Adjusted EBITDA excludes some, but not all, items that affect net income (loss) and net cash provided by operating activities, and these measures may vary among companies. Management compensates for the limitations of Adjusted EBITDA as an analytical tool by reviewing the comparable GAAP measures, understanding the differences between the measures and incorporating this knowledge into their decision making processes.

Distributable Cash Flow
We define DCF as net income (loss) plus non-cash interest expense, non-cash income tax expense, depreciation and amortization expense, unit-based compensation expense, impairment of compression equipment, impairment of goodwill, certain transaction fees, severance charges, loss (gain) on disposition of assets, proceeds from insurance recovery and other, less distributions on Preferred Units and maintenance capital expenditures.
We believe DCF is an important measure of operating performance because it allows management, investors and others to compare basic cash flows we generate (after distributions on the Preferred Units but prior to any retained cash reserves established by the General Partner and the effect of the DRIP) to the cash distributions we expect to pay our common unitholders. Using DCF, management can quickly compute the coverage ratio of estimated cash flows to planned cash distributions.
DCF should not be considered an alternative to, or more meaningful than, net income (loss), operating income (loss), cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP as measures of operating performance and liquidity. Moreover, our DCF 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, the interest cost of acquiring compression equipment and maintenance capital expenditures are necessary elements of our costs. Unit-based compensation expense related to equity awards to employees is also a necessary component of our business. Therefore, measures that exclude these elements have material limitations. To compensate for these limitations, we believe that it is important to consider both net income (loss) and net cash provided by operating activities determined under GAAP, as well as DCF, 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 by operating activities, and these measures may vary among companies. Management compensates for the limitations of DCF as an analytical tool by reviewing the comparable GAAP measures, understanding the differences between the measures and incorporating this knowledge into their decision making processes.

Coverage Ratios
DCF Coverage Ratio is defined as DCF divided by distributions declared to common unitholders in respect of such period. Cash Coverage Ratio is defined as DCF 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 others to gauge our ability to pay cash distributions to common unitholders using the cash flows that we generate. Our DCF Coverage Ratio and Cash Coverage Ratio as presented may not be comparable to similarly titled measures of other companies.

​ITEM 3. Quantitative and Qualitative Disclosures About Market Risk
Commodity Price Risk
Market 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 with our services and, accordingly, have no direct exposure to fluctuating commodity prices. However, the demand for our compression services depends upon the continued 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 the production 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 to fluctuating commodity prices. A one percent decrease in average revenue generating horsepower for the six months ended June 30, 2020 would result in an annual decrease of approximately $6.6 million in revenue and $4.5 million in Adjusted gross margin. Adjusted gross margin is a non-GAAP financial measure. For a reconciliation of Adjusted gross margin to gross margin, its most directly comparable financial measure, calculated and presented in accordance with GAAP, please read Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Non-GAAP Financial Measures” of this report.
Interest Rate Risk​
We are exposed to market risk due to variable interest rates under our financing arrangements.
As of June 30, 2020, we had $447.8 million of variable-rate indebtedness outstanding at a weighted average interest rate of 2.77%. A one percent increase or decrease in the effective interest rate on our variable-rate outstanding debt as of June 30, 2020 would result in an annual increase or decrease in our interest expense of approximately $4.5 million.
For further information regarding our exposure to interest rate fluctuations on our debt obligations, see Note 8 to our unaudited condensed consolidated financial statements under Part I, Item 1 “Financial Statements” of this report. Although we do not currently hedge our variable rate debt, we may, in the future, hedge all or a portion of such debt.
Credit Risk
Our credit exposure generally relates to receivables for services provided. We cannot currently predict the duration or magnitude of the effects of the COVID-19 pandemic and crude oil market volatility on our customers and their ability to pay amounts due, but if any significant customer of ours should have credit or financial problems resulting in a delay or failure to pay the amount it owes us, it could have a material adverse effect on our business, financial condition, results of operations and cash flows. Please see Part II, Item 1A. “Risk Factors” for more information regarding credit risk of our customers, suppliers and vendors.

ITEM 4. Controls and Procedures
Management’s Evaluation of Disclosure Controls and Procedures
As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures, and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of June 30, 2020 at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.  OTHER INFORMATION
ITEM 1. Legal Proceedings
From time to time, we may be involved in various legal or governmental proceedings 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.
ITEM 1A. Risk Factors
Security holders and potential investors in our securities should carefully consider the risk factors set forth in Part I, Item 1A. “Risk Factors” of our 2019 Annual Report and in Part II, Item 1A. “Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020. We have identified these risk factors as important factors that could cause our actual results to differ materially from those contained in any written or oral forward-looking statements made by us or on our behalf.
