ARCHROCK, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Basis of Presentation

We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We believe we are the leading provider of natural gas compression services to customers in the oil and natural gas industry throughout the U.S. and a leading supplier of aftermarket services to customers that own compression equipment in the U.S. We operate in two business segments: contract operations and aftermarket services. Our predominant segment, contract operations, primarily includes designing, sourcing, owning, installing, operating, servicing, repairing and maintaining our owned fleet of natural gas compression equipment to provide natural gas compression services to our customers. In our aftermarket services business, we sell parts and components and provide operations, maintenance, overhaul and reconfiguration services to customers who own compression equipment.

The accompanying unaudited condensed consolidated financial statements included herein have been prepared in accordance with GAAP and the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP are not required in these interim financial statements and have been condensed or omitted. Management believes that the information furnished includes all adjustments, consisting only of normal recurring adjustments, which are necessary to present fairly our consolidated financial position, results of operations and cash flows for the periods indicated. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements presented in our 2018 Form 10-K, which contains a more comprehensive summary of our accounting policies. The interim results reported herein are not necessarily indicative of results for a full year. Certain prior year amounts have been reclassified to conform to the current year presentation.

Recent Business Developments

Elite Acquisition

On June 23, 2019, we entered into an asset purchase agreement with Elite Compression pursuant to which we will acquire from Elite Compression substantially all of its assets, including a fleet of predominantly-large compressor units comprising approximately 430,000 horsepower, a fleet of vehicles, real personal property and parts inventory, and certain liabilities for aggregate consideration of $205.0 million cash and 21,656,683 newly-issued shares of Archrock common stock. We intend to fund the cash portion of the purchase price with borrowings on the Credit Facility. The Elite Acquisition is expected to close in the third quarter of 2019 subject to certain closing conditions and the consummation of the Harvest Sale (see below).

Harvest Sale

On June 23, 2019, we entered into an asset purchase agreement with Harvest pursuant to which Harvest will acquire from us approximately 80,000 active and idle compression horsepower, vehicles and parts inventory for consideration of $30 million to be paid in cash. The Harvest Sale is expected to close in the third quarter of 2019, subject to customary closing conditions.

During the three and six months ended June 30, 2019, we incurred transaction costs of $2.5 million related to the Elite Acquisition and Harvest Sale, which is reflected in transaction-related costs in our condensed consolidated statements of operations.

2. Recent Accounting Developments

Accounting Standards Updates Implemented

Leases

ASC 842 Leases establishes a ROU model that requires a lessee to record a ROU asset and a lease liability on the balance sheet. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. Under the new guidance, lessor accounting is largely unchanged. We adopted ASC 842 Leases on January 1, 2019 using the modified retrospective transition method and elected the practical expedient package to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) lease classification of any expired or existing leases and (iii) initial direct costs for any existing leases. We did not elect the practical expedient to use hindsight in determining the lease term. Adoption of ASC 842 Leases resulted in recognition of an operating lease ROU asset of $18.6 million and an operating lease liability of $20.0 million in our condensed consolidated balance sheet at January 1, 2019. The difference of $1.4 million related to accrued rent and prepaid lease payments recorded to our consolidated balance sheet as of December 31, 2018. We did not recognize any finance lease ROU assets or liabilities upon adoption of ASC 842 Leases. There was no impact to our condensed consolidated statements of operations, equity or cash flows upon adoption. Comparative information has not been recast and continues to be reported under the accounting standards in effect for those periods.

ASC 842 Leases also provides a practical expedient, elected by class of underlying asset, to not separate lease and nonlease components and instead account for those components as a single component if certain conditions are met. ASC 842 Leases also provides clarification for lessors on whether ASC 842 Leases or ASC 606 Revenue is applicable to the combined component based on determination of the predominant component. We have concluded that for our contract operations services agreements, in which we are a lessor, the services nonlease component is predominant over the compression unit lease component and therefore ongoing recognition of these agreements will continue to follow the ASC 606 Revenue guidance. We have also elected, as a lessee, to not separate lease and nonlease components as it relates to our facility leases.

In addition, we have made an accounting policy election, as permitted by ASC 842 Leases, to not apply the recognition requirements of ASC 842 Leases to leases with an initial term of 12 months or less.

Accounting Standards Updates Not Yet Implemented

In August 2018, the FASB issued ASU 2018-13 which amends the required fair value measurements disclosures related to valuation techniques and inputs used, uncertainty in measurement and changes in measurements applied. These amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. We are currently evaluating the impact of ASU 2018-13 on our consolidated financial statements and footnote disclosures.

In June 2016, the FASB issued ASU 2016-13 which changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in earlier recognition of allowance for losses. For public entities that meet the definition of an SEC filer, ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 and early adoption is permitted. Entities will apply ASU 2016-13 provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements and footnote disclosures.

3. Discontinued Operations

In 2015 we completed the Spin-off. In order to effect the Spin-off and govern our relationship with Exterran Corporation after the Spin-off, we entered into several agreements with Exterran Corporation which include, but are not limited to, the tax matters agreement. The tax matters agreement governs the respective rights, responsibilities and obligations of Exterran Corporation and us with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and certain other matters regarding taxes. Subject to the provisions of this agreement, we and Exterran Corporation agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin-off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing.

Table of Contents

As of June 30, 2019 and December 31, 2018, we had $8.5 million and $7.1 million, respectively, of unrecognized tax benefits (including interest and penalties) related to Exterran Corporation operations prior to the Spin-off recorded to noncurrent liabilities associated with discontinued operations in our condensed consolidated balance sheets. We had an offsetting indemnification asset of $8.5 million and $7.1 million related to these unrecognized tax benefits recorded to noncurrent assets associated with discontinued operations as of June 30, 2019 and December 31, 2018, respectively.

Archrock Credit Facility

In April 2018, in connection with the Merger and Amendment No. 1, the Archrock Credit Facility was terminated. As a result of the termination, we recorded a debt extinguishment loss of $2.5 million during the three and six months ended June 30, 2018. We incurred $0.2 million in commitment fees in 2018 prior to the facility’s termination and were in compliance with all covenants through its closing.

Credit Facility

As of June 30, 2019, there were $15.2 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.7%. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 5.3% and 5.4% at June 30, 2019 and December 31, 2018, respectively. We incurred $0.6 million in commitment fees on the daily unused amount of the Credit Facility during each of the three months ended June 30, 2019 and 2018 and $1.1 million during each of the six months ended June 30, 2019 and 2018.

We must maintain the following consolidated financial ratios, as defined in the Credit Facility agreement:



EBITDA to Interest Expense	2.5 to 1.0
Senior Secured Debt to EBITDA	3.5 to 1.0
Total Debt to EBITDA
Through fiscal year 2019	5.75 to 1.0
Through second quarter of 2020	5.50 to 1.0
Thereafter ⁽¹⁾	5.25 to 1.0

——————


⁽¹⁾	Subject to a temporary increase to 5.5 to 1.0 for any quarter during which an acquisition satisfying certain thresholds is completed and for the two quarters immediately following such quarter.

As of June 30, 2019, the ratio requirements above did not constrain our undrawn capacity and as such, all of the $442.3 million of undrawn capacity was available for additional borrowings. As of June 30, 2019, we were in compliance with all covenants under the Credit Facility agreement.

2027 Notes

On March 21, 2019, we completed a private offering of $500.0 million aggregate principal amount of 6.875% senior notes due April 2027 and received net proceeds of $491.2 million after deducting issuance costs. The $8.8 million of issuance costs were recorded as deferred financing costs within long-term debt in our condensed consolidated balance sheets and are being amortized to interest expense in our condensed consolidated statement of operations over the term of the notes. The net proceeds were used to repay borrowings outstanding under the Credit Facility as of March 31, 2019.

The 2027 Notes have not been and will not be registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the U.S. except pursuant to a registration exemption under the Securities Act and applicable state securities laws. We offered and issued the 2027 Notes only to qualified institutional buyers in accordance with Rule 144A under the Securities Act and to certain non-U.S. persons outside the U.S. in accordance with Regulation S under the Securities Act.

The 2027 Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by us and all of our existing subsidiaries, other than Archrock Partners, L.P. and APLP Finance Corp., which are co-issuers of the 2027 Notes, and certain of our future subsidiaries. The 2027 Notes and the guarantees rank equally in right of payment with all of our and the guarantors’ existing and future senior indebtedness.

The 2027 Notes may be redeemed at any time, in whole or in part, at specified redemption prices and make-whole premiums, plus any accrued and unpaid interest.

Redemption of 2021 Notes

On April 5, 2019, the 2021 Notes were redeemed at 100% of their $350.0 million aggregate principal amount plus accrued and unpaid interest of $0.2 million with borrowings from the Credit Facility. We recorded a debt extinguishment loss of $3.7 million related to the redemption during the three and six months ended June 30, 2019.

——————


⁽¹⁾	We operate in two segments: contract operations and aftermarket services. See Note 19 (“Segments”) for further details regarding our segments.


⁽²⁾	Primarily related to fees associated with Archrock-owned non-compressor equipment.


⁽³⁾	Included $2.2 million and $1.4 million for the three months ended June 30, 2019 and 2018, respectively, and $4.4 million and $2.7 million for the six months ended June 30, 2019 and 2018, respectively, related to billable maintenance on Archrock-owned units that was recognized at a point in time. All other contract operations revenue is recognized over time.


⁽⁴⁾	All service revenue within aftermarket services is recognized over time. All OTC parts and components sales revenue is recognized at a point in time.

Performance Obligations

As of June 30, 2019, we had $312.9 million of remaining performance obligations related to our contract operations segment. We have elected to apply the practical expedient to not consider the effects of the time value of money, as the expected time between the transfer of services and payment for such services is less than one year. The remaining performance obligations will be recognized through 2024 as follows (in thousands):



	2019		2020		2021		2022		2023		2024		Total
Remaining performance obligations	$	148,323	$	117,192	$	37,632	$	8,295	$	1,122	$	293	$	312,857

As of June 30, 2019 we have elected to apply the practical expedient to not disclose the aggregate transaction price for the remaining performance obligations for aftermarket services, as there are no contracts with customers with an original contract term that is greater than one year.

Contract Balances

As of June 30, 2019 and December 31, 2018, our receivables from contracts with customers, net of allowance for doubtful accounts, were $139.3 million and $142.1 million, respectively. As of June 30, 2019 and December 31, 2018, our contract liabilities were $11.6 million and $17.1 million, respectively, which are included in deferred revenue and other liabilities in our condensed consolidated balance sheets. Freight billings to customers for the transport of compressor assets and milestone billings on aftermarket services often result in a contract liability. We recognized $25.2 million of our December 31, 2018 contract liability balance as revenue during the six months ended June 30, 2019, primarily related to freight billings and aftermarket services.

Table of Contents

8. Leases

We determine if an arrangement is a lease at inception. We determine lease classification and recognize ROU assets and liabilities on the lease commencement date based on the present value of lease payments over the lease term. As the discount rate implicit in the lease is rarely readily determinable, we estimate our incremental borrowing rate using information available at commencement date in determining the present value of the lease payments. The lease term includes options to extend when we are reasonably certain to exercise the option. Short-term leases, those with an initial term of 12 months or less, are not recorded on the balance sheet. Variable costs such as our proportionate share of actual costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are recognized in the period in which they are incurred. Operating lease expense for lease payments is recognized on a straight-line basis over the term of the lease. As of June 30, 2019, all of our leases were operating.

The facility leases discussed below, of which we are the lessee, contain lease and nonlease components for which we have elected the practical expedient to account for as a single lease component, as the nonlease components are not significant to the total consideration in the contract and separating the nonlease component would have no effect on lease classification. As it relates to our contract operations services agreements in which we are the lessor, the services nonlease component is predominant over the compression unit lease component and therefore ongoing recognition of these agreements will continue to follow the ASC 606 Revenue guidance.

We have operating leases and subleases for office space, temporary housing, storage and shops. Our leases have remaining lease terms of one to 11 years and most include options to extend the lease term, at our discretion, for an additional three to five years. We are not, however, reasonably certain that we will exercise any of the options to extend and as such, they have not been included in the remaining lease terms.

9. Derivatives

We are exposed to market risks associated with changes in the variable interest rate of the Credit Facility. We use derivative instruments to manage our exposure to fluctuations in this variable interest rate and thereby minimize the risks and costs associated with financial activities. We do not use derivative instruments for trading or other speculative purposes.

At June 30, 2019, the following interest rate swaps, entered into to offset changes in expected cash flows due to fluctuations in the associated variable interest rates, were outstanding (in millions):



Expiration Date	Notional Value
May 2020	$	100
March 2022	300
	$	400

The counterparties to the derivative agreements are major financial institutions. We monitor the credit quality of these financial institutions and do not expect non-performance by any counterparty, although such non-performance could have a material adverse effect on us. We have no collateral posted for the derivative instruments.

We have designated these interest rate swaps as cash flow hedging instruments. Changes in the fair value of the interest rate swaps are recognized as a component of other comprehensive income (loss) until the hedged transaction affects earnings. At that time, amounts are reclassified into earnings to interest expense, the same statement of operations line item to which the earnings effect of the hedged item is recorded. Cash flows from derivatives designated as hedges are classified in our condensed consolidated statements of cash flows under the same category as the cash flows from the underlying assets, liabilities or anticipated transactions, unless the derivative contract contains a significant financing element; in this case, the cash settlements for these derivatives are classified as cash flows from financing activities.

We expect the hedging relationship to be highly effective as the swap terms substantially coincide with the hedged item and are expected to offset changes in expected cash flows due to fluctuations in the variable rate. We perform quarterly qualitative prospective and retrospective hedge effectiveness assessments unless facts and circumstances related to the hedging relationships change such that we can no longer assert qualitatively that the cash flow hedge relationships were and continue to be highly effective. We estimate that $0.3 million of the deferred pre-tax gain attributable to interest rate swaps included in accumulated other comprehensive income at June 30, 2019 will be reclassified into earnings as interest income at then-current values during the next 12 months as the underlying hedged transactions occur.

As of June 30, 2019, the weighted average effective fixed interest rate on the interest rate swaps was 1.8%.

The following table presents the effect of the derivative instruments designated as cash flow hedging instruments in our condensed consolidated balance sheets (in thousands):

See Note 10 (“Fair Value Measurements”) and Note 17 (“Accumulated Other Comprehensive Income (Loss)”) for further details on our derivative instruments.

10. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

On a quarterly basis, our interest rate swaps are valued based on the income approach (discounted cash flow) using market observable inputs, including London Interbank Offered Rate forward curves. These fair value measurements are classified as Level 2. The following table presents our interest rate swaps asset and liability measured at fair value on a recurring basis, with pricing levels as of the date of valuation (in thousands):



	June 30, 2019			December 31, 2018
Interest rate swaps asset	$	336		$	7,307
Interest rate swaps liability	(1,574		)	—

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

During the six months ended June 30, 2019, we recorded non-recurring fair value measurements related to our idle and previously-culled compressor units. Our estimate of the compressor units’ fair value was primarily based on the expected net sale proceeds compared to other fleet units we recently sold and/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. We discounted the expected proceeds, net of selling and other carrying costs, using a weighted average disposal period of four years. These fair value measurements are classified as Level 3. The fair value of our impaired compressor units was $1.6 million and $2.3 million at June 30, 2019 and December 31, 2018, respectively. See Note 11 (“Long-Lived Asset Impairment”) for further details.

Other Financial Instruments

The carrying amounts of our cash, receivables and payables approximate fair value due to the short-term nature of those instruments.

The carrying amount of borrowings outstanding under the Credit Facility approximates fair value due to its variable interest rate. The fair value of these outstanding borrowings was estimated using a discounted cash flow analysis based on interest rates offered on loans with similar terms to borrowers of similar credit quality, which are Level 3 inputs.

⁽¹⁾	Carrying amounts are shown net of unamortized debt discounts and unamortized deferred financing costs. See Note 6 (“Long-Term Debt”).

11. Long-Lived Asset Impairment

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable.

We periodically review the future deployment of our idle compression assets for units that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. Based on these reviews, we determine that certain idle compressor units should be retired from the active fleet. The retirement of these units from the active fleet triggers a review of these assets for impairment and as a result of our review, we may record an asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit is estimated based on the expected net sale proceeds compared to other fleet units we recently sold, a review of other units recently offered for sale by third parties or the estimated component value of the equipment we plan to use.

In connection with our review of our idle compression assets, we evaluate for impairment idle units that were culled from our fleet in prior years and are available for sale. Based on that review, we may reduce the expected proceeds from disposition and record additional impairment to reduce the book value of each unit to its estimated fair value.

The following table presents the results of our impairment review as recorded in our contract operations segment (dollars in thousands):



	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Idle compressor units retired from the active fleet	160		120		180		165
Horsepower of idle compressor units retired from the active fleet	41,000		27,000		56,000		50,000
Impairment recorded on idle compressor units retired from the active fleet	$	8,632	$	6,953	$	11,724	$	11,663

12. Hosting Arrangements

In the fourth quarter of 2018 we began a process and technology transformation project that will, among other things, upgrade our existing ERP system, improve our supply chain and inventory management and expand the remote monitoring capabilities of our compression fleet. Included in this project is the implementation of hosting arrangements that are service contracts related to the cloud migration of our ERP system and hosted cloud services for our new mobile workforce telematics tool.

Certain costs incurred for the implementation of our hosting arrangements that are service contracts are being capitalized and will be amortized on a straight-line basis over the term of the respective contract. As of June 30, 2019 and December 31, 2018, we had $2.0 million and $0.4 million, respectively, of implementation costs related to our hosting arrangements that are service contracts capitalized to other assets in our condensed consolidated balance sheets. Amortization of the capitalized implementation costs will be recorded to SG&A in our consolidated statements of income and is expected to begin in future periods as the individual contract components become ready for their intended use.

13. Income Taxes

The year-to-date effective tax rate for the six months ended June 30, 2019 differed significantly from our statutory rate primarily due to the reduction of a valuation allowance, which was recorded to offset the tax effect of the increase in book income in the six months ended June 30, 2019, as well as the release of an unrecognized tax benefit due to the settlement of a tax audit.

Unrecognized Tax Benefits

As of June 30, 2019, we believe it is reasonably possible that $1.9 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to June 30, 2020 due to the settlement of audits or the expiration of statutes of limitations or both. However, due to the uncertain and complex application of the tax regulations, it is possible that the ultimate resolution of these matters may result in liabilities which could materially differ from this estimate.

14. Earnings per Share

Net Income (Loss) Attributable to Archrock Common Stockholders per Common Share

Basic net income (loss) attributable to Archrock common stockholders per common share is computed using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Under the two-class method, basic net income (loss) attributable to Archrock common stockholders per common share is determined by dividing net income (loss) attributable to Archrock common stockholders after deducting amounts allocated to participating securities, by the weighted average number of common shares outstanding for the period. Participating securities include unvested restricted stock and stock-settled restricted stock units that have nonforfeitable rights to receive dividends or dividend equivalents, whether paid or unpaid. During periods of net loss, no effect is given to participating securities because they do not have a contractual obligation to participate in our losses.

Diluted net income (loss) attributable to Archrock common stockholders per common share is computed using the weighted average number of shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding options, performance-based restricted stock units and stock to be issued pursuant to our employee stock purchase plan unless their effect would be anti-dilutive.

The following table summarizes net income (loss) attributable to Archrock common stockholders used in the calculation of basic and diluted net income (loss) per common share (in thousands):

15. Equity

Merger Transaction

In April 2018, we completed the Merger and acquired all of the common units of the Partnership not owned by us prior to the Merger. As a result of the Merger, the Partnership’s common units are no longer publicly traded. The 2021 Notes and 2022 Notes were not impacted by the Merger.

As we controlled the Partnership prior to the Merger and continue to control the Partnership after the Merger, we accounted for the change in our ownership interest in the Partnership as an equity transaction in the second quarter of 2018 and no gain or loss was recognized in our condensed consolidated statements of operations as a result of the Merger. The tax effects of the Merger were reported as adjustments to other assets, noncurrent assets associated with discontinued operations, deferred income taxes, additional paid-in capital and other comprehensive income.

Table of Contents

The following table presents the effects of changes in our ownership interest in the Partnership on the equity attributable to Archrock stockholders:



	Six Months Ended June 30, 2018

Decrease in Archrock stockholders’ additional paid-in capital for purchase of Partnership common units	52,815
Change from net loss attributable to Archrock stockholders and transfers from noncontrolling interest	$	50,936

Prior to the Merger, public unitholders held a 57% ownership interest in the Partnership and we owned the remaining 43% equity interest. The earnings of the Partnership that were attributed to its common units held by the public prior to the Merger are reflected in net income attributable to the noncontrolling interest in our condensed consolidated statements of operations.

16. Stock-Based Compensation

We have granted restricted stock, restricted stock units and performance-based restricted stock units to employees and non-employee directors under the Archrock, Inc. 2013 Stock Incentive Plan.

The following table presents restricted stock, restricted stock unit, performance-based restricted stock unit and cash-settled performance unit activity during the six months ended June 30, 2019:



	Shares (in thousands)		Weighted Average Grant Date Fair Value Per Share
Non-vested awards, January 1, 2019	1,728		$	9.68
Granted	1,383		10.01
Vested	(402	)	6.33
Canceled	(153	)	10.33
Non-vested awards, June 30, 2019 ⁽¹⁾⁽²⁾	2,556		10.35

——————


⁽¹⁾	Non-vested awards as of June 30, 2019 are comprised of 451,000 cash-settled restricted stock units and cash-settled performance units and 2,105,000 restricted shares and stock-settled performance units.

⁽²⁾

During the three months ended June 30, 2019, the settlement terms of 99,631 performance units, with grant dates in 2018 and 2019, were modified from settlement in stock to cash. The change in award settlement from stock to cash was the only modification to these awards; the vesting, forfeiture and all other terms and conditions were unchanged. The modification resulted in a $0.2 million reclassification from additional paid-in capital to other current liabilities in our condensed consolidated balance sheets and had an immaterial impact on our condensed consolidated statements of operations.

As of June 30, 2019, we expect $18.5 million of unrecognized compensation cost related to unvested restricted stock, stock-settled restricted stock units, performance units, cash-settled restricted stock units and cash-settled performance units to be recognized over the weighted-average period of 2.2 years.

Total stock-based compensation expense consisted of the following (in thousands):



	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Equity awards	$	1,512	$	1,969	$	3,869	$	3,763
Liability awards	640		666		1,606		967
Total stock-based compensation	$	2,152	$	2,635	$	5,475	$	4,730

17. Accumulated Other Comprehensive Income (Loss)

Components of comprehensive income (loss) are net income (loss) and all changes in equity during a period except those resulting from transactions with owners. Our accumulated other comprehensive income consists of changes in the fair value of our interest rate swap derivative instruments, net of tax, which are designated as cash flow hedges, amortization of terminated interest rate swaps and adjustments related to changes in our ownership of the Partnership.

Table of Contents

The following table presents the changes in accumulated other comprehensive income (loss) of our derivative cash flow hedges, net of tax and excluding noncontrolling interest, during the three and six months ended June 30, 2019 and 2018 (in thousands):

——————


⁽¹⁾	Included adjustments of $1.1 million and $1.8 million related to an increase in the valuation allowance recorded to offset the tax effect of other comprehensive loss recorded during the three and six months ended June 30, 2019, respectively.


⁽²⁾	Included stranded tax effects resulting from the Tax Cuts and Jobs Act, which was implemented in December 2017, of $0.3 million reclassified to accumulated deficit during the six months ended June 30, 2018.


⁽³⁾	Pursuant to the Merger, we reclassified a gain of $5.7 million from noncontrolling interest to accumulated other comprehensive income (loss) related to the fair value of our derivative instruments that was previously attributed to public ownership of the Partnership.

See Note 9 (“Derivatives”) for further details on our interest rate swap derivative instruments.

18. Commitments and Contingencies

Performance Bonds

In the normal course of business we have issued performance bonds to various state authorities that ensure payment of certain obligations. We have also issued a bond to protect our 401(k) retirement plan against losses caused by acts of fraud or dishonesty. The bonds have expiration dates in 2019 through the third quarter of 2020 and maximum potential future payments of $2.3 million. As of June 30, 2019, we were in compliance with all obligations to which the performance bonds pertain.

Tax Matters

We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of each of June 30, 2019 and December 31, 2018, we accrued $4.5 million for the outcomes of non-income-based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We believe the likelihood is remote that the impact of potential unasserted claims from non-income-based tax audits could be material to our consolidated financial position, but it is possible that the resolution of future audits could be material to our consolidated results of operations or cash flows.

Subject to the provisions of the tax matters agreement between Exterran Corporation and us, both parties agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin-off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing. The tax contingencies mentioned above relate to tax matters for which we are responsible in managing the audit. As of June 30, 2019 and December 31, 2018, we recorded an indemnification liability (including penalties and interest), in addition to the tax contingency above, of $2.7 million and $2.6 million, respectively, for our share of non-income-based tax contingencies related to audits being managed by Exterran Corporation.

Insurance Matters

Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability and commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance coverage is customary for the industry and adequate for our business; however, losses and liabilities not covered by insurance would increase our costs.

Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages.

Litigation and Claims

In the ordinary course of business, we are involved in various pending or threatened legal actions. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from any of these actions will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends.

19. Segments

We manage our business segments primarily based on the type of product or service provided. We have two segments which we operate within the U.S.: contract operations and aftermarket services. The contract operations segment primarily provides natural gas compression services to meet specific customer requirements. The aftermarket services segment provides a full range of services to support the compression needs of customers, from part sales and normal maintenance services to full operation of a customer’s owned assets.

We evaluate the performance of our segments based on gross margin for each segment. Revenue includes only sales to external customers.

The following table presents revenue and gross margin by segment during the three and six months ended June 30, 2019 and 2018 (in thousands):

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited financial statements and the notes thereto included in the Financial Statements of this Quarterly Report on Form 10-Q and in conjunction with our 2018 Form 10-K.

Overview

We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We believe we are the leading provider of natural gas compression services to customers in the oil and natural gas industry throughout the U.S. and a leading supplier of aftermarket services to customers that own compression equipment in the U.S. We operate in two business segments: contract operations and aftermarket services. Our contract operations services primarily include designing, sourcing, owning, installing, operating, servicing, repairing and maintaining our owned fleet of natural gas compression equipment to provide natural gas compression services to our customers. In our aftermarket services business, we sell parts and components and provide operations, maintenance, overhaul and reconfiguration services to customers who own compression equipment.

Recent Business Developments

Elite Acquisition and Harvest Sale

On June 23, 2019, we entered into an asset purchase agreement with Elite Compression pursuant to which we will acquire from Elite Compression substantially all of its assets, including a fleet of predominantly-large compressor units comprising approximately 430,000 horsepower, a fleet of vehicles, real personal property and parts inventory, and certain liabilities for aggregate consideration of $205.0 million cash and 21,656,683 newly-issued shares of Archrock common stock. The Elite Acquisition is expected to close in the third quarter of 2019 subject to certain closing conditions and the consummation of the Harvest Sale.

Additionally, on June 23, 2019, we entered into an asset purchase agreement with Harvest pursuant to which Harvest will acquire from us approximately 80,000 active and idle compression horsepower, vehicles and parts inventory for cash consideration of $30 million.

See Note 1 (“Organization and Basis of Presentation”) to our Financial Statements for further details of these transactions.

Senior Notes Offering and Redemption

On March 21, 2019, we completed a private offering of $500.0 million aggregate principal amount of the 2027 Notes. We received net proceeds of $491.2 million after issuance costs which were used to repay borrowings outstanding under the Credit Facility as of March 31, 2019. On April 5, 2019, we borrowed on the Credit Facility to repay the 2021 Notes. See Note 6 (“Long-Term Debt”) to our Financial Statements for further details of these transactions.

Non-GAAP Financial Measures

Management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include the non-GAAP financial measure of gross margin.

We define gross margin as total revenue less cost of sales (excluding depreciation and amortization). Gross margin is included as a supplemental disclosure because it is a primary measure used by our management to evaluate the results of revenue and cost of sales (excluding depreciation and amortization), which are key components of our operations. We believe gross margin is important because it focuses on the current operating performance of our operations and excludes the impact of the prior historical costs of the assets acquired or constructed that are utilized in those operations, the indirect costs associated with our SG&A activities, the impact of our financing methods and income taxes. In addition, depreciation and amortization may not accurately reflect the costs required to maintain and replenish the operational usage of our assets and therefore may not portray the costs of current operating activity. As an indicator of our operating performance, gross margin should not be considered an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP. Our gross margin may not be comparable to a similarly-titled measure of other companies because other entities may not calculate gross margin in the same manner.

Gross margin has certain material limitations associated with its use as compared to net income (loss). These limitations are primarily due to the exclusion of SG&A, depreciation and amortization, impairments, restatement and other charges, interest expense, debt extinguishment loss, transaction-related costs, other (income) loss, net, provision for (benefit from) income taxes and loss from discontinued operations, net of tax. Because we intend to finance a portion of our operations through borrowings, interest expense is a necessary element of our costs and our ability to generate revenue. Additionally, because we use capital assets, depreciation expense is a necessary element of our costs and our ability to generate revenue and SG&A is necessary to support our operations and required corporate activities. To compensate for these limitations, management uses this non-GAAP measure as a supplemental measure to other GAAP results to provide a more complete understanding of our performance.

Financial Results of Operations

Summary of Results

Revenue. Revenue was $238.4 million and $226.9 million during the three months ended June 30, 2019 and 2018, respectively, and $474.5 million and $438.9 million during the six months ended June 30, 2019 and 2018, respectively. The increases in revenue during the three and six months ended June 30, 2019 compared to the three and six months ended June 30, 2018 were due to increases in revenue from our contract operations business.

Net income (loss) attributable to Archrock stockholders. Net income attributable to Archrock stockholders was $11.4 million and $1.9 million during the three months ended June 30, 2019 and 2018, respectively. Net income attributable to Archrock stockholders was $30.9 million and net loss attributable to Archrock stockholders was $1.9 million during the six months ended June 30, 2019 and 2018, respectively.

The increase in net income attributable to Archrock stockholders during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was primarily driven by the increase in gross margin from our contract operations business and decreases in transaction-related costs and net income attributable to the noncontrolling interest, partially offset by the change from benefit from income taxes to provision for income taxes and increases in interest expense, depreciation and amortization and SG&A.

The change from net loss to net income attributable to Archrock stockholders during the six ended June 30, 2019 compared to the six months ended June 30, 2018 was primarily driven by the increase in gross margin from our contract operations business and decreases in net income attributable to the noncontrolling interest and transaction-related costs, partially offset by increases in interest expense and SG&A.

⁽¹⁾ Defined as gross margin divided by revenue.

The increase in revenue during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was primarily due to an increase in contract operations rates driven by an increase in customer demand as well as the increase in average operating horsepower.

Gross margin increased during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 primarily due to the increase in revenue mentioned above partially offset by the increase in cost of sales. The increase in cost of sales was primarily driven by an increase in maintenance and freight expense associated with the increase in average operating horsepower. These increases in cost of sales were partially offset by a decrease in cost associated with the start-up of compressor units, as the increase in average operating horsepower was mostly comprised of newly-built compressor units.

Gross margin percentage increased during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 primarily due to the increase in contract operations rates mentioned above.

Selling, general and administrative. The increase in SG&A during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was primarily due to a $1.5 million increase in professional expenses, a $1.4 million increase in compensation and benefits and a $0.3 million increase in office rent expense. These increases were partially offset by a $0.6 million decrease in miscellaneous tax expense and a $0.4 million decrease in bad debt expense.

Depreciation and amortization. The increase in depreciation and amortization expense during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was primarily due to an increase in depreciation expense associated with fixed asset additions, partially offset by a decrease in depreciation expense resulting from certain assets reaching the end of their depreciable lives as well as the impact of asset impairments during 2018 and early 2019.

Long-lived asset impairment. During the three months ended June 30, 2019 and 2018, we reviewed the future deployment of our idle compression assets for units that were not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. In addition, we evaluated for impairment idle units that had been culled from our fleet in prior years and were available for sale. See Note 11 (“Long-Lived Asset Impairment”) to our Financial Statements for further details.

The following table presents the results of our impairment review as recorded in our contract operations segment (dollars in thousands):



	Three Months Ended June 30,

Idle compressor units retired from the active fleet	160		120
Horsepower of idle compressor units retired from the active fleet	41,000		27,000
Impairment recorded on idle compressor units retired from the active fleet	$	8,632	$	6,953

Restatement and other charges. During the three months ended June 30, 2018, we recorded $1.6 million for the expected recovery of shared professional and legal fees incurred related to the restatement of prior period financial statements and disclosures and related matters. We were billed $0.5 million for our share of these fees during the three months ended June 30, 2018.

Interest expense. The increase in interest expense during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was due to an increase in the average outstanding balance of long-term debt.

Debt extinguishment loss. We recorded a debt extinguishment loss of $3.7 million during the three months ended June 30, 2019 as a result of the redemption of the 2021 Notes. We recorded a debt extinguishment loss of $2.5 million during the three months ended June 30, 2018 as a result of the termination of the Archrock Credit Facility. See Note 6 (“Long-Term Debt”) to our Financial Statements for further details.

Transaction-related costs. We incurred $2.7 million and $5.7 million of financial advisory, legal and other professional fees during the three months ended June 30, 2019 and 2018, respectively. Of the $2.7 million of fees incurred during the three months ended June 30, 2019, $2.5 million related to the Elite Acquisition and Harvest Sale. The $5.7 million of fees incurred during the three months ended June 30, 2018 related to the Merger. See Note 1 (“Organization and Basis of Presentation”) and Note 15 (“Equity”) to our Financial Statements for further details.

Other income, net. The increase in other income, net during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was primarily due to a $0.8 million increase in the gain on sale of property, plant and equipment and income of $0.3 million during the three months ended June 30, 2019 related to equipment damaged at a customer site, partially offset by $0.5 million of indemnification income received pursuant to our tax matters agreement with Exterran Corporation during the three months ended June 30, 2018.

Effective tax rate	9		%	(61		)%	70	%

The change in provision for (benefit from) income taxes was primarily due to the reduction of a valuation allowance in the three months ended June 30, 2019, which was recorded to offset the tax effect of the increase in book income in the three months ended June 30, 2019 compared to the three months ended June 30, 2018, as well as the release of an unrecognized tax benefit due to the settlement of a tax audit during the three months ended June 30, 2018.

The noncontrolling interest comprises the portion of the Partnership’s earnings that were applicable to the Partnership’s publicly-held common unitholder interest through the completion of the Merger. See Note 15 (“Equity”) to our Financial Statements for further details on the Merger. Immediately prior to the Merger, public unitholders held a 57% ownership in the Partnership. The decrease in net income attributable to the noncontrolling interest during the three months ended June 30, 2019 compared to the three months ended June 30, 2018 was due to Archrock’s acquisition of all of the outstanding common units of the Partnership in conjunction with the Merger.

Interest expense. The increase in interest expense during the six months ended June 30, 2019 compared to the six months ended June 30, 2018 was primarily due to an increase in the average outstanding balance of long-term debt partially offset by a decrease in the weighted average effective interest rate.

Liquidity and Capital Resources

Overview

Our ability to fund operations, finance capital expenditures and pay dividends depends on the levels of our operating cash flows and access to the capital and credit markets. Our primary sources of liquidity are cash flows generated from our operations and our borrowing availability under the Credit Facility. Our cash flow is affected by numerous factors including prices and demand for our services, volatility in commodity prices and their effect on oil and natural gas exploration and production spending, conditions in the financial markets and other factors. We believe that our operating cash flows and borrowings under the Credit Facility will be sufficient to meet our liquidity needs through at least June 30, 2020.

We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.

Capital Requirements

Our contract operations business is capital intensive, requiring significant investment to maintain and upgrade existing operations. Our capital spending is primarily dependent on the demand for our contract operations services and the availability of the type of compression equipment required for us to provide those contract operations services to our customers. Our capital requirements have consisted primarily of, and we anticipate will continue to consist of, the following:


•	growth capital expenditures, which are made to expand or to replace partially or fully depreciated assets or to expand the operating capacity or revenue-generating capabilities of existing or new assets, whether through construction, acquisition or modification; and


•	maintenance capital expenditures, which are made to maintain the existing operating capacity of our assets and related cash flows, further extending the useful lives of the assets.

Table of Contents

The majority of our growth capital expenditures are related to the acquisition cost of new compressor units that we add to our fleet. In addition to the cost of newly acquired compressor units, growth capital expenditures can also include the upgrading of major components on an existing compressor unit where the current configuration of the compressor unit is no longer in demand and the compressor is not likely to return to an operating status without the capital expenditures. These latter expenditures substantially modify the operating parameters of the compressor unit such that it can be used in applications for which it previously was not suited. Maintenance capital expenditures are related to major overhauls of significant components of a compressor unit, such as the engine, compressor and cooler, which return the components to a like-new condition but do not modify the applications for which the compressor unit was designed.

We generally invest funds necessary to purchase fleet additions when our idle equipment cannot be reconfigured to economically fulfill a project’s requirements and the new equipment expenditure is expected to generate economic returns over its expected useful life that exceed our targeted return on capital. We currently plan to spend approximately $375 million to $400 million in capital expenditures during 2019, primarily consisting of approximately $285 million to $300 million for growth capital expenditures and approximately $60 million to $65 million for maintenance capital expenditures.

Financial Resources

Revolving Credit Facilities

Archrock Credit Facility. In April 2018, in connection with the Merger and Amendment No. 1, we terminated the Archrock Credit Facility and borrowed on the Credit Facility to repay $63.2 million in borrowings and accrued and unpaid interest and fees outstanding. All commitments under the Archrock Credit Facility were terminated and the $15.4 million of letters of credit outstanding under the Archrock Credit Facility were converted to letters of credit under the Credit Facility. Prior to its termination, the Archrock Credit Facility required us to maintain various financial ratios and other covenants, all of which we were in compliance with through its closing. The average daily debt balance under the Archrock Credit Facility in 2018, through its closing in April 2018, was $51.7 million.

Credit Facility. During the six months ended June 30, 2019 and 2018, the Credit Facility had an average daily debt balance of $784.0 million and $717.1 million, respectively. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 5.3% and 5.4% at June 30, 2019 and December 31, 2018, respectively. As of June 30, 2019, there were $15.2 million letters of credit outstanding under the Credit Facility.

We must maintain the following consolidated financial ratios, as defined in the Credit Facility agreement:



EBITDA to Interest Expense	2.5 to 1.0
Senior Secured Debt to EBITDA	3.5 to 1.0
Total Debt to EBITDA
Through fiscal year 2019	5.75 to 1.0
Through second quarter of 2020	5.50 to 1.0
Thereafter ⁽¹⁾	5.25 to 1.0

——————


⁽¹⁾	Subject to a temporary increase to 5.50 to 1.0 for any quarter during which an acquisition satisfying certain thresholds is completed and for the two quarters immediately following such quarter.

As of June 30, 2019, the ratio requirements above did not constrain our undrawn capacity and as such, all of the $442.3 million of undrawn capacity was available for additional borrowings.

The Credit Facility agreement contains various additional covenants including, but not limited to, mandatory prepayments from the net cash proceeds of certain asset transfers, restrictions on the use of proceeds from borrowings and limitations on our ability to incur additional indebtedness, engage in transactions with affiliates, merge or consolidate, sell assets, make certain investments and acquisitions, make loans, grant liens, repurchase equity and pay distributions. In addition, if as of any date we have cash and cash equivalents (other than proceeds from a debt or equity issuance received in the 30 days prior to such date reasonably expected to be used to fund an acquisition permitted under the Credit Facility agreement) in excess of $50.0 million, then such excess amount will be used to pay down outstanding borrowings of a corresponding amount under the Credit Facility. As of June 30, 2019, we were in compliance with all covenants under the Credit Facility.

2027 Notes Offering and Redemption of 2021 Notes

On March 21, 2019, we completed a private offering of $500.0 million aggregate principal amount of 6.875% senior notes due April 2027 and received net proceeds of $491.2 million after deducting issuance costs of $8.8 million related to the offering. The net proceeds were used to repay borrowings outstanding under the Credit Facility as of March 31, 2019. On April 5, 2019, we borrowed on the Credit Facility to repay the $350.0 million of 2021 Notes. See Note 6 (“Long-Term Debt”) for further details of these transactions.

Cash Flows

Our cash flows from operating, investing and financing activities, as reflected in the condensed consolidated statements of cash flows, are summarized in the table below (in thousands):



	Six Months Ended June 30,

Financing activities	60,084			508
Net decrease in cash and cash equivalents	$	(3,595	)	$	(7,004	)

Operating Activities

The increase in net cash provided by operating activities from continuing operations during the six months ended June 30, 2019 compared to the six months ended June 30, 2018 was primarily due to increases in revenue and deferred revenue in our contract operations business primarily driven by increased customer demand, receipt of cash proceeds pursuant to a settlement of certain sales and use tax audits and a decrease in accounts receivable. These increases in cash inflows were partially offset by an increase in interest paid as the result of an increase in the average outstanding balance of our long-term debt during the six months ended June 30, 2019 compared to the six months ended June 30, 2018.

Investing Activities

The increase in net cash used in investing activities from continuing operations during the six months ended June 30, 2019 compared to the six months ended June 30, 2018 was primarily due to a $102.8 million increase in capital expenditures, partially offset by a $2.8 million increase in proceeds from sale of property, plant and equipment.

Financing Activities

The increase in net cash provided by financing activities during the six months ended June 30, 2019 compared to the six months ended June 30, 2018 was primarily due to a $62.8 million net increase in borrowings of long-term debt and an $11.8 million decrease in distributions paid to noncontrolling partners in the Partnership. These changes were partially offset by a $10.4 million increase in dividends paid to Archrock stockholders and a $5.5 million increase in payments for debt issuance costs.

Dividends

On July 24, 2019, our board of directors declared a quarterly dividend of $0.145 per share of common stock to be paid on August 14, 2019 to stockholders of record at the close of business on August 7, 2019. Any future determinations to pay cash dividends to our stockholders will be at the discretion of our board of directors and will be dependent upon our financial condition, results of operations and credit and loan agreements in effect at that time and other factors deemed relevant by our board of directors.

Based on the evaluation, as of June 30, 2019 our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed in reports that we file or submit under the Exchange Act is accumulated and communicated to management, and made known to our principal executive officer and principal financial officer, on a timely basis to ensure that it is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors

The following risk factors became significant to us in the second quarter of 2019 and should be read in conjunction with the risk factors previously disclosed in our 2018 Form 10-K.

The proposed Elite Acquisition may require significant time and attention of our management, and we may not achieve the intended benefits of the transaction as and when expected, or at all. Difficulties with the integration of the Elite Compression business and workforce could have an adverse effect on our business.

On June 23, 2019, we entered into an asset purchase agreement with Elite Compression pursuant to which we will acquire from Elite Compression substantially all of its assets, liabilities and workforce for aggregate consideration of $205.0 million cash and 21,656,683 newly-issued shares of Archrock common stock. The Elite Acquisition is expected to close in the third quarter of 2019, subject to certain customary closing conditions and the consummation of the Harvest Sale. See Note 1 (“Organization and Basis of Presentation”) to our Financial Statements for further details of these transactions.

The integration of Elite Compression will continue to require significant expense, time and the attention of our management, which may divert resources away from the operation of our business and the execution of our other strategic initiatives. In addition, we will operate a larger combined organization and the difficulties associated with integrating the acquired assets, infrastructure and personnel into our existing operations may require additional time or expense. Our and Elite Compression’s employees may also be uncertain about their future roles within Archrock pending the completion of the Elite Acquisition, which could lead to departures and increased expenses related to hiring and training new employees. Further, if the Elite Acquisition is completed, we may not realize the benefits we expect to realize. Any such difficulties could have an adverse effect on our business, results of operations and financial condition.

Further, we may not be successful in integrating the proposed Elite Acquisition into our existing operations within our anticipated timeframe, which may result in unforeseen operational difficulties and expenses, diminish our financial performance or require a disproportionate amount of our management’s attention to address. In addition, the acquired business or assets may perform at levels below the levels we anticipated at the time of acquiring such business or assets due to factors beyond our control. As a result, there can be no assurance that the proposed Elite Acquisition will deliver the benefits anticipated by us, and any failure to create such benefits may result in a negative impact to, or material adverse effect on, our business, results of operations, financial condition and cash flows.

The proposed Elite Acquisition will result in our dependence on Hilcorp for a significant portion of our revenue. The loss of business with Hilcorp or the inability or failure of Hilcorp to meet its payment obligations may adversely affect our financial results.

In connection with the proposed Elite Acquisition, Elite Compression’s contract operations services agreements will transfer to us and we expect that Hilcorp, the primary customer of Elite Compression, will account for a significant portion of our future revenue.

During the year ended December 31, 2018, Hilcorp accounted for approximately 1% of our revenue. If the Elite Acquisition is completed, we estimate that Hilcorp will become one of our most significant customers. Any loss of business from Hilcorp, unless offset by additional contract compression services revenue from other customers, or the inability or failure of Hilcorp to meet its payment obligations could have a material adverse effect on our business, results of operations and financial condition.

Table of Contents

Following the closing of the proposed Elite Acquisition, an affiliate of Hilcorp will hold a significant portion of our common stock, and Hilcorp’s interest as an equity holder may conflict with the interests of our other shareholders or our noteholders.

In connection with the closing of the proposed Elite Acquisition, JDH Capital, an affiliate of Hilcorp, will receive 21,656,683 newly-issued shares of Archrock common stock, representing 16.6% of outstanding Archrock common stock as of June 30, 2019. As long as JDH Capital, together with affiliates of Hilcorp, continues to own at least 7.5% of the outstanding Archrock common stock, it will have the right to nominate one director to our board of directors. Given its ownership level and board representation, JDH Capital may have some influence over our operations and strategic direction and may have interests that conflict with the interests of other equity and debt holders.
