NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Summary of Significant Accounting Policies

The accompanying unaudited condensed consolidated financial statements of Archrock included herein have been prepared in accordance with U.S. GAAP for interim financial information 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 2017 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.

Organization

We are a pure play U.S. natural gas contract operations services business and 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 primary business segments: contract operations and aftermarket services. In our contract operations business, we use our owned fleet of natural gas compression equipment to provide operations services to our customers. In our aftermarket services business line, we sell parts and components and provide operations, maintenance, overhaul and reconfiguration services to customers who own compression equipment.

We have a significant equity interest in the Partnership, a master limited partnership that provides natural gas contract operations services to customers throughout the U.S. As of March 31, 2018, public unitholders held an approximate 57% ownership interest in the Partnership and we owned the remaining equity interest, including all of the general partner interest and incentive distribution rights.

Merger Transaction

On April 26, 2018, we completed the acquisition of all of the outstanding common units of the Partnership at a fixed exchange ratio of 1.40 shares of our common stock for each common unit of the Partnership not owned by us. In connection with the closing of the Merger, we issued an aggregate of 57.6 million shares of our common stock to unaffiliated holders of common units of the Partnership in exchange for all of the 41.2 million common units of the Partnership not owned by us. Additionally, the incentive distribution rights in the Partnership, which were previously owned indirectly by us, were canceled and ceased to exist. As a result of the Merger, common units of the Partnership are no longer publicly traded. See Note 18 (“Subsequent Events”) for further details of this transaction.

Significant Accounting Policies

Income (Loss) Attributable to Archrock Common Stockholders Per Common Share

Basic 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 income (loss) attributable to Archrock common stockholders per common share is determined by dividing 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 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 and stock to be issued pursuant to our employee stock purchase plan unless their effect would be anti-dilutive.

Table of Contents

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

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 (loss) consists of changes in the fair value of derivative instruments, net of tax, that 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) by component, net of tax, and excluding noncontrolling interest, during the three months ended March 31, 2017 and 2018 (in thousands):

During the three months ended March 31, 2018, we reclassified a loss of $0.2 million to interest expense and an immaterial tax benefit to provision for (benefit from) income taxes in our condensed consolidated statements of operations from accumulated other comprehensive income (loss). Additionally, we reclassified stranded tax effects resulting from the TCJA of $0.3 million to accumulated deficit in our condensed consolidated balance sheets. See Note 2 (“Recent Accounting Developments”) for further detail.

2. Recent Accounting Developments

Accounting Standards Updates Implemented

ASU 2018-05 was issued in March 2018 to clarify the ASC 740 disclosure requirements as they pertain to SAB 118, including the requirement to disclose a reasonable estimate, if determinable, of the tax effects of the TCJA in the reporting period in which the TCJA was enacted, as well as additional disclosures required in the following interim reporting periods if the measurement period approach is used. In accordance with this ASU, we disclosed a reasonable estimate of the income tax effects of the TCJA on our consolidated financial statements in our 2017 Form 10-K and there have been no changes to this estimate. We anticipate finalizing the amounts in connection with the completion of our 2017 income tax returns in the fourth quarter of 2018.

On January 1, 2018, we adopted ASU 2018-02 which allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the TCJA. As a result of the TCJA’s corporate rate reduction, we had $0.3 million of stranded tax effects in accumulated other comprehensive income related to our derivative instruments and terminated interest rate swaps, which we elected to reclassify to accumulated deficit.

On January 1, 2018, we adopted ASU 2017-12 using the modified retrospective approach to existing cash flow hedge relationships as of January 1, 2018. ASU 2017-12 expands and refines hedge accounting for both nonfinancial and financial risk components, aligns the recognition and presentation of the effects of the hedging instrument and hedged item in the financial statements and eliminates the requirement to separately measure and report hedge ineffectiveness. As a result of the adoption of ASU 2017-12, we recognized a net gain of $0.4 million as a cumulative-effect adjustment to opening retained earnings, with a corresponding adjustment to other comprehensive income (loss), to reverse the cumulative ineffectiveness previously recognized in interest expense.

On January 1, 2018, we adopted ASU 2016-15 on a retrospective basis. ASU 2016-15 addresses diversity in practice and simplifies several elements of cash flow classification, including how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 did not have an impact on our condensed consolidated statement of cash flow for the three months ended March 31, 2017.

Revenue Recognition Update

On January 1, 2018, we adopted the Revenue Recognition Update using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. We recognized the cumulative effect of initially applying the Revenue Recognition Update as an adjustment to the opening balance of retained earnings. For contracts that were modified before the effective date, we identified performance obligations on the basis of the current version of the contract, which included any contract modifications since inception. The application of the practical expedient for contract modifications did not have a material effect on the adjustment to retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Under previous guidance, contract operations revenue was recognized when earned, which generally occurs monthly when the service is provided under our customer contracts. Under the Revenue Recognition Update the timing of revenue recognition is impacted by contractual provisions for service availability guarantees of our compressor assets and re-billable costs associated with moving our compressor assets to a customer site. These changes are further discussed below and did not result in a material difference from previous practice for contract operations.

The Revenue Recognition Update resulted in a significant change related to our aftermarket services operations, maintenance, overhaul and reconfiguration services. Under previous guidance, revenue was recognized on a completed contract basis as products were delivered and title was transferred or services were performed for the customer. Under the Revenue Recognition Update, these services are recognized as revenue over time, using output or input methods to measure the progress toward complete satisfaction of the performance obligation based on the nature of the goods or services being provided. The adoption did not result in a material difference in the amount or timing of revenues for aftermarket services parts and components sales.

The Revenue Recognition Update provides guidance on contract costs that should be recognized as assets and amortized over the period that the related goods or services transfer to the customer. Certain costs that were previously expensed as incurred, such as sales commissions and freight charges to transport compressor assets, are deferred and amortized.

The following table summarizes the cumulative impact of the adoption of the new standard on the opening balance sheet (in thousands):

Accounting Standards Updates Not Yet Implemented

In June 2016, the FASB issued ASU 2016-13 that 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 the earlier recognition of allowance for losses. 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.

Table of Contents

In February 2016, the FASB issued ASU 2016-02 that establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be 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. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. We are currently evaluating the impact of ASU 2016-02 on our consolidated financial statements.

3. Revenue from Contracts with Customers

Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we are entitled to receive in exchange for those goods or services. Sales and usage-based taxes that are collected from the customer are excluded from revenue.

The following table presents our revenue from contracts with customers disaggregated by revenue source (in thousands):



	Three Months Ended March 31, 2018
Contract Operations ⁽¹⁾:
0 - 1000 horsepower per unit	$	59,592
1,001 - 1,500 horsepower per unit	66,230
Over 1,500 horsepower per unit	34,410
Other ⁽²⁾	965
Total contract operations ⁽³⁾	161,197

Aftermarket Services ⁽¹⁾:
Services	32,207
OTC parts and components sales	18,636
Total aftermarket services ⁽⁴⁾	50,843

Total revenue ⁽⁵⁾	$	212,040

——————


⁽¹⁾	We operate in two segments: contract operations and aftermarket services. See Note 16 (“Segments”) for further details regarding our segments.


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


⁽³⁾	Includes $1.3 million for the three months ended March 31, 2018 related to billable maintenance on Archrock-owned units that was recognized at a point in time. All other revenue within contract operations 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.

Contract Operations

We provide comprehensive contract operations services including the personnel, equipment, tools, materials and supplies to meet our customers’ natural gas compression needs. Based on the operating specifications at the customer location and each customer's unique needs, these services include designing, sourcing, owning, installing, operating, servicing, repairing and maintaining equipment to provide natural gas compression services to our customers.

Natural gas compression services are generally satisfied over time, as the customer simultaneously receives and consumes the benefits provided by these services. Our performance obligation is a series in which the unit of service is one month, as the customer receives substantially the same benefit each month from the services regardless of the type of service activity performed, which may vary. If the transaction price is based on a fixed fee, revenue is recognized monthly on a straight-line basis over the period that we are providing services to the customer. Amounts invoiced to customers for costs associated with moving our compressor assets to a customer site are also included in the transaction price and are amortized over the initial contract term.

Table of Contents

Variable consideration exists if customers are billed at a lesser standby rate when a unit is not running. We have elected to apply the invoicing practical expedient to recognize revenue for such variable consideration, as the invoice corresponds directly to the value transferred to the customer based on our performance completed to date. The rate for standby service is lower to reflect the decrease in costs and effort required to provide standby service when a unit is not running.

We also perform billable maintenance service on our natural gas compression equipment at the customer’s request on an as-needed basis. The performance obligation is satisfied, and revenue is recognized at the agreed-upon transaction price, at the point in time when service is complete and the customer has accepted the work performed and can obtain the remaining benefits of the service that the unit will provide.

As of March 31, 2018, we had $180.8 million of remaining performance obligations related to our contract operations segment. This amount does not reflect revenue for contracts whose original expected duration is less than 12 months or performance obligations for which we recognize revenue under the invoicing practical expedient discussed above. In addition, 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 2021 as follows (in thousands):



	2018		2019		2020		2021		Total
Contract operations remaining performance obligations	$	115,746	$	49,182	$	12,977	$	2,865	$	180,770

Aftermarket Services

We provide a full range of services to support the compression needs of customers. We sell OTC parts and components and provide operations, maintenance, overhaul and reconfiguration services to customers who own compression equipment.

We sell OTC parts and components needed for the maintenance or repair of customer-owned compression equipment. The performance obligation is generally satisfied at the point in time when delivery takes place and the customer obtains control of the part or component. The transaction price is the fixed sales price for the part stated in the contract. Revenue is recognized upon delivery, as we have a present right to payment and the customer has legal title.

Our aftermarket service activities include operations, maintenance, overhaul and reconfiguration services on customer-owned compression equipment on an as-needed basis or as part of a monthly maintenance schedule. The service activities performance obligation is satisfied over time, as the work performed enhances the customer-controlled asset and another entity would not have to substantially re-perform the work we completed if they were to fulfill the remaining performance obligation. The transaction price may be a fixed monthly service fee, a fixed quoted fee or entirely variable, calculated on a time and materials basis.

For service provided based on a fixed monthly fee, the performance obligation is a series in which the unit of service is one month. The customer receives substantially the same benefit each month from the service, regardless of the type of service activity performed, which may vary. As the progress towards satisfaction of the performance obligation is measured based on the passage of time, revenue is recognized monthly based on the fixed fee provided for in the contract.

For service provided based on a quoted fixed fee, progress towards satisfaction of the performance obligation is measured using an input method based on the actual amount of labor and material costs incurred. The amount of the transaction price recognized as revenue each reporting period is determined by multiplying the transaction price by the ratio of actual costs incurred to date to total estimated costs expected for the service. Significant judgment is involved in the estimation of the progress to completion. Any adjustments to the measure of the progress to completion will be accounted for on a prospective basis. Changes to the scope of service is recognized as an adjustment to the transaction price in the period in which the change occurs.

Service provided based on time and materials are generally short-term in nature and labor rates and parts pricing is agreed upon prior to commencing the service. We have elected to use the right-to-invoice practical expedient using an estimated gross margin percentage applied to actual costs incurred. The estimated gross margin percentage is fixed based on historical time and materials-based service. We evaluate the estimated gross margin percentage at the end of each reporting period and adjust the transaction price as appropriate.

Table of Contents

We believe these fee- and cost-based inputs fairly depict our efforts to provide aftermarket services and the amount of revenue recognized is representative of the transfer of service and value that the customer will have received as of the reporting date. As of March 31, 2018 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

Contract operations services are generally billed monthly at the beginning of the month in which service is being provided. For aftermarket services, billings will typically occur when parts are delivered or when service is complete; however, milestone billings may be used in longer-term projects. We recognize a contract asset when we have the right to consideration in exchange for goods or services transferred to a customer when the right is conditioned on something other than the passage of time. We recognize a contract liability when we have an obligation to transfer goods or services to a customer for which we have already received consideration. Freight billings to transport compressor assets and milestone billings on aftermarket services often result in a contract liability.

As of March 31, and January 1, 2018, our receivables from contracts with customers, net of allowance for doubtful accounts were $110.8 million and $115.6 million, respectively. As of March 31, and January 1, 2018, our contract liabilities were $9.2 million and $9.0 million, respectively, which are included in deferred revenue and other long-term liabilities in our condensed consolidated balance sheets. The increase in the contract liability balance was due to deferral of $4.5 million primarily related to freight billings, partially offset by $4.3 million which was recognized as revenue during the period primarily related to freight billings and aftermarket services.

4. Discontinued Operations

Spin-off of Exterran Corporation

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 separation and distribution agreement, the tax matters agreement and the supply agreement. Certain terms of these agreements are described as follows:

•

The separation and distribution agreement specifies our right to receive payments from a subsidiary of Exterran Corporation based on a notional amount corresponding to payments received by Exterran Corporation’s subsidiaries from PDVSA Gas, in respect of the sale of Exterran Corporation’s subsidiaries’ and joint ventures’ previously nationalized assets promptly after such amounts are collected by Exterran Corporation’s subsidiaries. During the three months ended March 31, 2017 we received $19.7 million from Exterran Corporation pursuant to this term of the separation and distribution agreement. Exterran Corporation was due to receive the remaining principal amount as of March 31, 2018 of approximately $20.9 million.

•

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 Exterran Corporation and we 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. As of March 31, 2018, we classified $6.4 million of unrecognized tax benefits (including interest and penalties) as long-term liability associated with discontinued operations since it relates to operations of Exterran Corporation prior to the Spin-off. We have also recorded an offsetting $6.4 million indemnification asset related to this reserve as long-term assets associated with discontinued operations.

•

The supply agreement, which expired November 2017, set forth the terms under which Exterran Corporation provided manufactured equipment, including the design, engineering, manufacturing and sale of natural gas compression equipment, on an exclusive basis to us and the Partnership, subject to certain exceptions. We have entered into a new non-exclusive supply agreement with Exterran Corporation to be one of our suppliers of newly-manufactured compression equipment. For the three months ended March 31, 2018 and March 31, 2017, we purchased $37.8 million and $37.2 million, respectively, of newly-manufactured compression equipment from Exterran Corporation and others.

Table of Contents

Generally, the separation and distribution agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of Exterran Corporation’s business with Exterran Corporation. Pursuant to the separation and distribution agreement, we and Exterran Corporation generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business.

Other discontinued operations activity

In December 2013, we abandoned our contract water treatment business as part of our continued emphasis on simplification and focus on our core businesses. The abandonment of this business meets the criteria established for recognition as discontinued operations under GAAP. Therefore certain deferred tax assets related to our contract water treatment business have been reported as discontinued operations in our condensed consolidated balance sheet. This business was previously included in our contract operations segment.

The following table summarizes the balance sheet data for discontinued operations (in thousands):

7. Contract Costs

We capitalize incremental costs to obtain a contract with a customer if we expect to recover those costs. Capitalized costs include commissions paid to our sales force to obtain contract operations contracts. We have applied the practical expedient to expense commissions paid for sales of service contracts and OTC parts and components within our aftermarket services segment as the amortization period is less than one year. As of March 31, and January 1, 2018, we recorded contract costs of $2.9 million and $2.3 million, respectively, associated with sales commissions.

We capitalize costs incurred to fulfill a contract if those costs relate directly to a contract, enhance resources that we will use in satisfying performance obligations and if we expect to recover those costs. Capitalized costs incurred to fulfill our customer contracts include freight charges to transport compressor assets before transferring services to the customer and mobilization activities associated with our contract operations services. As of March 31, and January 1, 2018, we recorded contract costs of $23.8 million and $19.2 million, respectively, associated with freight and mobilization.

Contract operations costs are amortized based on the transfer of service to which the assets relate, which is estimated to be 36 months based on average contract term, including anticipated renewals. We assess periodically whether the 36-month estimate fairly represents the average contract term and adjust as appropriate. Aftermarket services fulfillment costs are recognized based on the percentage-of-completion method applicable to the customer contract. Contract costs associated with commissions are amortized to SG&A. Contract costs associated with freight and mobilization are amortized to cost of sales (excluding depreciation and amortization). During the three months ended March 31, 2018, we amortized $0.3 million and $2.6 million related to commissions and freight and mobilization, respectively. During the three months ended March 31, 2018, there was no impairment loss recorded in relation to the costs capitalized.

Credit Facility

The Archrock Credit Facility is a five-year, $350.0 million revolving credit facility with a maturity of November 2020. As of March 31, 2018, we had $15.4 million in outstanding letters of credit under the Archrock Credit Facility and the applicable margin on amounts outstanding was 1.8%. The weighted average annual interest rate, excluding the effect of interest rate swaps, on the outstanding balance under the Archrock Credit Facility was 3.6% and 2.8% at March 31, 2018 and 2017, respectively. We incurred $0.2 million in commitment fees on the daily unused amount of the Archrock Credit Facility during each of the three months ended March 31, 2018 and 2017.

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



EBITDA to Interest Expense	2.25 to 1.0
Total Debt to EBITDA ⁽¹⁾	4.25 to 1.0

——————


⁽¹⁾	Subject to a temporary increase to 4.75 to 1.0 for any quarter during which an acquisition meeting certain thresholds is completed and for the following two quarters after the quarter in which the acquisition closes.

As of March 31, 2018, we had undrawn capacity of $282.1 million under the Archrock Credit Facility. As a result of the Total Debt to EBITDA ratio limitation, $224.2 million of the $282.1 million undrawn capacity under the Archrock Credit Facility was available for additional borrowings as of March 31, 2018. As of March 31, 2018, we were in compliance with all covenants under the Archrock Credit Facility.

In connection with the Merger and Amendment No. 1, the Archrock Credit Facility was terminated on April 26, 2018. See Note 18 (“Subsequent Events”) for further details of the Merger and Amendment No. 1.

Partnership Credit Facility

The Partnership Credit Facility is a five-year, $1.1 billion asset-based revolving credit facility that will mature on March 30, 2022, except that if any portion of the Partnership’s 6% senior notes due April 2021 are outstanding as of December 2, 2020, then maturity will instead be on December 2, 2020. In March 2017, the Partnership incurred $14.9 million in transaction costs related to the formation of the Partnership Credit Facility. Concurrent with entering into the Partnership Credit Facility, the Partnership expensed $0.6 million of unamortized deferred financing costs and recorded a debt extinguishment loss of $0.3 million related to the termination of its Former Credit Facility.

Table of Contents

As of March 31, 2018, the Partnership had no outstanding letters of credit under the Partnership Credit Facility and the applicable margin on amounts outstanding was 3.3%. The weighted average annual interest rate on the outstanding balance under the Partnership Credit Facility, excluding the effect of interest rate swaps, was 5.1% and 6.3% at March 31, 2018 and 2017, respectively.

The Partnership incurred $0.5 million and $0.4 million in commitment fees on the daily unused amount of the Partnership Credit Facility and the Former Credit Facility during the three months ended March 31, 2018 and 2017, respectively.

On February 23, 2018, the Partnership amended the Partnership Credit Facility to, among other things, increase the maximum Total Debt to EBITDA ratio. The Partnership must maintain the following consolidated financial ratios, as defined in the Partnership 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 2018	5.95 to 1.0
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 meeting certain thresholds is completed and for the following two quarters after the quarter in which the acquisition closes.

As of March 31, 2018, the Partnership had undrawn capacity of $413.0 million under the Partnership Credit Facility. As a result of the financial ratio requirements discussed above, $177.2 million of the $413.0 million of undrawn capacity was available for additional borrowings as of March 31, 2018. As of March 31, 2018, the Partnership was in compliance with all covenants under the Partnership Credit Facility agreement.

Amendment No. 1 amended certain other terms of the Partnership Credit Facility effective upon completion of the Merger on April 26, 2018. See Note 18 (“Subsequent Events”) for further details.

9. Derivatives

We are exposed to market risks associated with changes in interest rates. We use derivative instruments to minimize the risks and costs associated with financial activities by managing our exposure to interest rate fluctuations on a portion of our debt obligations. We do not use derivative instruments for trading or other speculative purposes.

At March 31, 2018, the Partnership was a party to the following interest rate swaps, which were entered into to offset changes in expected cash flows due to fluctuations in the associated variable interest rates:



Expiration Date	Notional Value (in millions)
May 2019	$	100.0
May 2020	100.0
March 2022	300.0
	$	500.0

Table of Contents

As of March 31, 2018, the weighted average effective fixed interest rate on the interest rate swaps was 1.8%. We have designated these interest rate swaps as cash flow hedging instruments so that any change in their fair values is recognized as a component of other comprehensive income (loss) until the hedged transaction affects earnings. At that time, amounts in other comprehensive income (loss) are reclassified into earnings and presented in the same income statement line item as the earnings effect of the hedged item. Prior to adoption of ASU 2017-12, we performed quarterly calculations to determine whether the swap agreements continued to be highly effective at achieving offsetting changes in cash flows attributable to the hedged risk. 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 expect the hedging relationship to continue to be highly effective. Upon adoption of ASU 2017-12, we perform subsequent quarterly prospective and retrospective hedge effectiveness assessments qualitatively 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 $1.5 million of deferred pre-tax gain attributable to interest rate swaps and included in our accumulated other comprehensive income (loss) at March 31, 2018, will be reclassified into earnings as interest income at then-current values during the next twelve months as the underlying hedged transactions occur. 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 in our condensed consolidated statements of cash flows.

In August 2017, the Partnership amended the terms of certain of its interest rate swap agreements, designated as cash flow hedges against the variability of future interest payments due under the Partnership Credit Facility, with a notional value of $300.0 million. The amended terms adjusted the fixed interest rate and extended the maturity dates to March 2022. These amendments effectively created new derivative contracts and terminated the old derivative contracts. As a result, as of the amendment date, we discontinued the original cash flow hedge relationships on a prospective basis and designated the amended interest rate swaps under new cash flow hedge relationships based on the amended terms. The fair value of the interest rate swaps immediately prior to the execution of the amendments was a liability of $0.7 million. The associated amount in accumulated other comprehensive income (loss) is being amortized into interest expense over the original terms of the interest rate swaps through May 2018.

The following tables present the effect of derivative instruments on our consolidated financial position and results of operations (in thousands):

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. The Partnership has no specific collateral posted for its derivative instruments.

10. Fair Value Measurements

The accounting standard for fair value measurements and disclosures establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value into the following three categories:


•	Level 1 — Quoted unadjusted prices for identical instruments in active markets to which we have access at the date of measurement.

•

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or prices vary substantially over time or among brokered market makers.


•	Level 3 — Model-derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect our own assumptions regarding how market participants would price the asset or liability based on the best available information.

Table of Contents

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 forward London Interbank Offered Rate 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):



	March 31, 2018		December 31, 2017
Interest rate swaps asset	$	9,810	$	4,676
Interest rate swaps liability	—		(134		)

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

During the three months ended March 31, 2018, 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 either 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 $0.4 million and $2.6 million at March 31, 2018 and December 31, 2017, 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 amounts of borrowings outstanding under our Archrock Credit Facility and the Partnership Credit Facility approximate fair value due to their variable interest rates. 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.

The fair value of our fixed rate debt was estimated based on quoted prices in inactive markets and is considered a Level 2 measurement. The following table summarizes the carrying amount and fair value of our fixed rate debt (in thousands):



	March 31, 2018		December 31, 2017
Carrying amount of fixed rate debt ⁽¹⁾	$	687,552	$	686,747
Fair value of fixed rate debt	700,000		702,000

——————


⁽¹⁾	Carrying amounts are shown net of unamortized debt discounts and unamortized deferred financing costs. See Note 8 (“Long-Term Debt”) for further details.

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.

Table of Contents

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 March 31,
	2018		2017
Idle compressor units retired from the active fleet	45		80
Horsepower of idle compressor units retired from the active fleet	22,000		28,000
Impairment recorded on idle compressor units retired from the active fleet	$	4,710	$	8,245

12. Restructuring and Other Charges

As discussed in Note 4 (“Discontinued Operations”), we completed the Spin-off in 2015. During the three months ended March 31, 2017, we incurred $0.5 million of costs for retention benefits associated with the Spin-off that were directly attributable to Archrock. The restructuring charges associated with the Spin-off are not directly attributable to our reportable segments because they primarily represent costs incurred within the corporate function. No additional costs were incurred under this program subsequent to the year ended December 31, 2017.

13. Stock-Based Compensation

Stock Incentive Plan

In April 2013, we adopted the 2013 Plan to provide for the granting of stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, other stock-based awards and dividend equivalent rights to employees, directors and consultants of Archrock. The 2013 Plan is administered by the compensation committee of our board of directors. Under the 2013 Plan, the maximum number of shares of common stock available for issuance pursuant to awards is 10,100,000. Each option and stock appreciation right granted counts as one share against the aggregate share limit, and any share subject to a stock settled award other than a stock option, stock appreciation right or other award for which the recipient pays intrinsic value counts as 1.75 shares against the aggregate share limit. Shares subject to awards granted under the 2013 Plan that are subsequently canceled, terminated, settled in cash or forfeited (excluding shares withheld to satisfy tax withholding obligations or to pay the exercise price of an option) are, to the extent of such cancellation, termination, settlement or forfeiture, available for future grant under the 2013 Plan. Cash-settled awards are not counted against the aggregate share limit. No additional grants have been or may be made under the 2007 Plan following the adoption of the 2013 Plan. Previous grants made under the 2007 Plan will continue to be governed by that plan and the applicable award agreements.

Stock Options

Stock options are granted at fair market value at the grant date, are exercisable according to the vesting schedule established by the compensation committee of our board of directors in its sole discretion and expire no later than seven years after the grant date. Stock options generally vest one-third per year on each of the first three anniversaries of the grant date, subject to continued service through the applicable vesting date.

The following table presents stock option activity during the three months ended March 31, 2018:



	Stock Options (in thousands)		Weighted Average Exercise Price Per Share		Weighted Average Remaining Life (in years)	Aggregate Intrinsic Value (in thousands)
Options outstanding, January 1, 2018	489		$	12.28
Canceled	(53	)	13.96
Options outstanding and exercisable, March 31, 2018	436		12.07		1.4	$	548

Intrinsic value is the difference between the market value of our stock and the exercise price of each stock option multiplied by the number of stock options outstanding for those stock options where the market value exceeds their exercise price.

Table of Contents

Restricted Stock, Stock-Settled Restricted Stock Units, Performance Units, Cash-Settled Restricted Stock Units and Cash Settled Performance Units

For grants of restricted stock, restricted stock units and performance units, we recognize compensation expense over the vesting period equal to the fair value of our common stock at the grant date. Our restricted stock, restricted stock units, and performance units include rights to receive dividends or dividend equivalents. We remeasure the fair value of cash-settled restricted stock units and cash-settled performance units and record a cumulative adjustment of the expense previously recognized. Our obligation related to the cash-settled restricted stock units and cash settled performance units is reflected as a liability in our condensed consolidated balance sheets. Restricted stock, stock-settled restricted stock units, cash-settled restricted stock units and cash-settled performance units generally vest one-third per year on dates as specified in the applicable award agreement, subject to continued service through the applicable vesting date. Stock-settled performance units cliff vest at the end of the performance period as specified in the terms of the applicable award agreement, subject to continued service through the applicable vesting date.

The following table presents restricted stock, restricted stock unit, performance unit, cash-settled restricted stock unit and cash- settled performance unit activity during the three months ended March 31, 2018:



	Shares (in thousands)		Weighted Average Grant Date Fair Value Per Share
Non-vested awards, January 1, 2018	1,440		$	10.39
Granted	1,089		9.50
Vested	(480	)	9.57
Canceled	(47	)	11.33
Non-vested awards, March 31, 2018 ⁽¹⁾	2,002		10.08

——————


⁽¹⁾	Non-vested awards as of March 31, 2018 are comprised of 272,000 cash-settled restricted stock units and cash-settled performance units and 1,730,000 restricted shares and stock-settled performance units.

As of March 31, 2018, we expect $17.0 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 2.7 years.

Partnership Long-Term Incentive Plan

In April 2017, the Partnership adopted the 2017 Partnership LTIP to provide for the benefit of employees, directors and consultants of the Partnership, us and our respective affiliates. Two million common units have been authorized for issuance with respect to awards under the 2017 Partnership LTIP. The 2017 Partnership LTIP provides for the issuance of unit options, unit appreciation rights, restricted units, phantom units, performance awards, bonus awards, distribution equivalent rights, cash awards and other unit based awards. The Partnership Plan is administered by the Partnership Plan Administrator. The 2006 Partnership LTIP expired in 2016 and as such no further grants have been or can be made under that plan following expiration. Previous grants made under the 2006 Partnership LTIP continue to be governed by the 2006 Partnership LTIP and the applicable award agreements.

Phantom units are notional units that entitle the grantee to receive common units upon the vesting of such phantom units or, at the discretion of the Partnership Plan Administrator, cash equal to the fair market value of such common units. Phantom units may include nonforfeitable tandem distribution equivalent rights to receive cash distributions on unvested phantom units in the quarter in which distributions are paid on common units. For grants of phantom units, we recognize compensation expense over the vesting period equal to the fair value of the Partnership’s common units at the grant date. Phantom units generally vest one-third per year on dates as specified in the applicable award agreements subject to continued service through the applicable vesting date.

Table of Contents

Partnership Phantom Units

The following table presents phantom unit activity during the three months ended March 31, 2018:



	Phantom Units (in thousands)		Weighted Average Grant Date Fair Value per Unit
Phantom units outstanding, January 1, 2018	153		$	12.19
Vested	(53	)	11.24
Phantom units outstanding, March 31, 2018	100		12.69

As of March 31, 2018, we expect $1.0 million of unrecognized compensation cost related to unvested phantom units to be recognized over the weighted-average period of 2.0 years.

14. Cash Dividends

The following table summarizes our dividends per common share:



Declaration Date	Payment Date	Dividends per Common Share		Total Dividends (in thousands)
January 19, 2017	February 15, 2017	$	0.12	$	8,458
April 26, 2017	May 16, 2017	0.12		8,534
July 26, 2017	August 15, 2017	0.12		8,536
October 20, 2017	November 15, 2017	0.12		8,536
January 18, 2018	February 14, 2018	0.12		8,532

15. 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 2018 through the first quarter of 2020 and maximum potential future payments of $2.3 million. As of March 31, 2018, 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 March 31, 2018 and December 31, 2017, we accrued $2.5 million and $1.7 million, respectively, 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 for the period in which the resolution occurs.

Table of Contents

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 both March 31, 2018 and December 31, 2017, we recorded an indemnification liability (including penalties and interest), in addition to the tax contingency above, of $1.6 million for our share of non-income 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. In addition, we have a minimal amount of insurance on our offshore assets. 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.

Indemnification Obligations

In connection with the Spin-off, we entered into a separation and distribution agreement which provides for cross-indemnities between Exterran Corporation’s operating subsidiary and us and established procedures for handling claims subject to indemnification and related matters. Generally, the separation and distribution agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of Exterran Corporation’s business with Exterran Corporation. Pursuant to the separation and distribution agreement, we and Exterran Corporation will generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business.

Litigation and Claims

In 2011, the Texas Legislature enacted changes related to the appraisal of natural gas compressors for ad valorem tax purposes by expanding the definitions of “Heavy Equipment Dealer” and “Heavy Equipment” effective from the beginning of 2012. Under the revised Heavy Equipment Statutes, we believe we are a Heavy Equipment Dealer, that our natural gas compressors are Heavy Equipment and that we, therefore, are required to file our ad valorem taxes under this new methodology. We further believe that our natural gas compressors are taxable under the Heavy Equipment Statutes in the counties where we maintain a business location and keep natural gas compressors instead of where the compressors may be located on January 1 of a tax year. As a result of this new methodology, our ad valorem tax expense (which is reflected in our condensed consolidated statements of operations as a component of cost of sales (excluding depreciation and amortization)) includes a benefit of $4.7 million during the three months ended March 31, 2018. Since the change in methodology became effective in 2012, we have recorded an aggregate benefit of $82.9 million as of March 31, 2018, of which $15.9 million has been agreed to by a number of appraisal review boards and county appraisal districts and $67.0 million has been disputed and is currently in litigation. A large number of appraisal review boards denied our position, although some accepted it, and our wholly owned subsidiary, Archrock Services Leasing LLC, formerly known as EES Leasing, and the Partnership’s subsidiary, Archrock Partners Leasing LLC, formerly known as EXLP Leasing, filed 176 petitions for review in the appropriate district courts with respect to the 2012 tax year, 109 petitions for review in the appropriate district courts with respect to the 2013 tax year, 115 petitions for review in the appropriate district courts with respect to the 2014 tax year, 120 petitions for review in the appropriate district courts with respect to the 2015 tax year, 113 petitions for review in the appropriate district courts with respect to the 2016 tax year and 112 petitions for review in the appropriate district courts with respect to the 2017 tax year.

To date, only five cases have advanced to the point of trial or submission of summary judgment motions on the merits, and only three cases have been decided, with two of the decisions having been rendered by the same presiding judge. All three of those decisions were appealed, and all three of the appeals have been decided by intermediate appellate courts.

On October 17, 2013, the 143rd Judicial District Court of Loving County, Texas ruled in EXLP Leasing LLC & EES Leasing LLC v. Loving County Appraisal District that EES Leasing and EXLP Leasing are Heavy Equipment Dealers and that their compressors qualify as Heavy Equipment, but the district court further held that the Heavy Equipment Statutes were unconstitutional as applied to EES Leasing’s and EXLP Leasing’s compressors. EES Leasing and EXLP Leasing appealed the district court’s constitutionality holding to the Eighth Court of Appeals in El Paso, Texas. On September 23, 2015, the Eighth Court of Appeals ruled in EES Leasing’s and EXLP Leasing’s favor by overruling the 143rd District Court’s constitutionality ruling. The Eighth Court of Appeals also ruled, however, that EES Leasing’s and EXLP Leasing’s natural gas compressors are taxable in the counties where they were located on January 1 of the tax year at issue.

On October 28, 2013, the 143rd Judicial District Court of Ward County, Texas ruled in EES Leasing LLC & EXLP Leasing LLC v. Ward County Appraisal District that EES Leasing and EXLP Leasing are Heavy Equipment Dealers and that their compressors qualify as Heavy Equipment, but the court held that the Heavy Equipment Statutes were unconstitutional as applied to their compressors. EES Leasing and EXLP Leasing appealed the district court’s constitutionality holding to the Eighth Court of Appeals in El Paso, Texas, and the Ward County Appraisal District cross-appealed the district court’s rulings that EES Leasing’s and EXLP Leasing’s compressors qualify as Heavy Equipment. On September 23, 2015, the Eighth Court of Appeals ruled in EES Leasing’s and EXLP Leasing’s favor by overruling the 143rd District Court’s constitutionality ruling and affirming its ruling that EES Leasing’s and EXLP Leasing’s compressors qualify as Heavy Equipment. The Eighth Court of Appeals also ruled, however, that EES Leasing’s and EXLP Leasing’s natural gas compressors are taxable in the counties where they were located on January 1 of the tax year at issue.

The Ward County Appraisal District and Loving County Appraisal District each filed (on January 27, 2016 and February 10, 2016, respectively) a petition asking the Texas Supreme Court to review its respective Eighth Court of Appeals decision. On March 11, 2016, EES Leasing and EXLP Leasing filed responses to the appraisal districts’ petitions and cross-petitions for review in each case asking the Texas Supreme Court to also review the Eighth Court of Appeals’ determination that natural gas compressors are taxable in the counties where they were located on January 1 of the tax year at issue. The Ward County Appraisal District filed its response to EES Leasing’s and EXLP Leasing’s cross-petition on June 6, 2016, and EES Leasing and EXLP Leasing filed their reply on June 21, 2016. The Loving County Appraisal District filed its response to EES Leasing’s and EXLP Leasing’s cross-petition on May 27, 2016, and EES Leasing and EXLP Leasing filed their reply on June 10, 2016.

On March 18, 2014, the 10th Judicial District Court of Galveston, Texas ruled in EXLP Leasing LLC & EES Leasing LLC v. Galveston Central Appraisal District that EES Leasing and EXLP Leasing are Heavy Equipment Dealers and that their compressors qualify as Heavy Equipment, but the court held the Heavy Equipment Statutes unconstitutional as applied to their compressors. EES Leasing and EXLP Leasing appealed the district court’s constitutionality holding to the Fourteenth Court of Appeals in Houston, Texas. On August 25, 2015, the Fourteenth Court of Appeals issued a ruling stating that EES Leasing’s and EXLP Leasing’s compressors are taxable in the counties where they were located on January 1 of the tax year at issue, and it remanded the case to the district court for further evidence on the issue of whether the Heavy Equipment Statutes are constitutional as applied to EES Leasing’s and EXLP Leasing’s compressors. On November 24, 2015, EES Leasing and EXLP Leasing filed a petition asking the Texas Supreme Court to review this decision. On March 21, 2016, the Galveston Central Appraisal District filed a response to EES Leasing’s and EXLP Leasing’s petition for review, and EES Leasing and EXLP Leasing filed their reply on April 26, 2016.

In EES Leasing v. Irion County Appraisal District, EES Leasing and the appraisal district each filed motions for summary judgment in the 51st District Court concerning the applicability and constitutionality of the Heavy Equipment Statutes. On May 20, 2014, the district court entered an order denying both motions for summary judgment, holding that a fact issue existed as to the applicability of the Heavy Equipment Statutes to the one compressor at issue. The presiding judge for the 51st District Court has since consolidated the 2012 tax year case with EES Leasing’s 2013 tax year case, which also included EXLP Leasing as a party. On August 27, 2015, the presiding judge abated the combined case, EES Leasing LLC and EXLP Leasing LLC v. Irion County Appraisal District, until the final resolution of the appellate cases considering the constitutionality of the Heavy Equipment Statutes, or further order of the court.

EES Leasing and EXLP Leasing also filed a motion for summary judgment in EES Leasing LLC & EXLP Leasing LLC v. Harris County Appraisal District, pending in the 189th Judicial District Court of Harris County, Texas. The court heard arguments on the motion on December 6, 2013 but has yet to rule. No trial date has been set.

On June 3, 2015, the Fourth Court of Appeals in San Antonio, Texas issued a decision reversing the 406th District Court’s dismissal of EES Leasing’s and EXLP Leasing’s tax appeals for want of jurisdiction. In EXLP Leasing LLC et. al v. Webb County Appraisal District, United Independent School District (“United ISD”) intervened as a party in interest and sought to dismiss the lawsuit arguing that the district court was without jurisdiction to hear the appeal. Under Section 42.08(b) of the Texas Tax Code, a property owner must pay before the delinquency date the lesser of (1) the amount of taxes due on the portion of the taxable value of the property that is not in dispute or (2) the amount of taxes due on the property under the order from which the appeal is taken. EES Leasing and EXLP Leasing paid zero taxes to Webb County because the entire amount of tax assessed by Webb County was in dispute. Instead, as required by the Heavy Equipment Statutes and Texas Comptroller forms, EES Leasing and EXLP Leasing paid taxes on the compressors at issue to Victoria County, where they maintain their place of business and keep natural gas compressors. The Webb County Appraisal District and United ISD contested EES Leasing’s and EXLP Leasing’s position that the Heavy Equipment Statutes contain situs provisions requiring that taxes be paid where the dealer has a business location and keeps its natural gas compressors, instead arguing that taxes are payable to the county where each compressor is located as of January 1 of the tax year at issue. The district court granted United ISD’s motion to dismiss on April 1, 2014 and declined EES Leasing’s and EXLP Leasing’s motion to reconsider. The Fourth Court of Appeals reversed, holding that, based on the plain meaning of Section 42.08(b)(1), and because the entire amount was in dispute, EES Leasing and EXLP Leasing were not required to prepay disputed taxes to invoke the trial court’s jurisdiction. The Fourth Court of Appeals denied United ISD’s request for a rehearing. On September 29, 2015, United ISD filed a petition for review in the Texas Supreme Court. On December 4, 2015, the Texas Supreme Court denied United ISD’s petition for review.

United ISD has four delinquency lawsuits pending against EES Leasing and EXLP Leasing in the 49th District Court of Webb County, Texas. The cases have been abated pending the resolution of EES Leasing’s and EXLP Leasing’s 2012 tax year case pending in the 406th Judicial District Court of Webb County, Texas.

On September 2, 2016, the Texas Supreme Court requested that consolidated merits briefs be filed in EES Leasing’s and EXLP Leasing’s cases against the Loving County Appraisal District, Ward County Appraisal District, and Galveston Central Appraisal District, as well as two similar cases involving different taxpayers. On September 19, 2016, the Supreme Court entered a consolidated briefing schedule for the five cases. Consolidated briefing was completed on February 7, 2017.

On March 10, 2017, the Texas Supreme Court granted EXLP Leasing’s and EES Leasing’s petition for review in EXLP Leasing LLC & EES Leasing LLC v. Galveston Central Appraisal District. The case was argued before the Texas Supreme Court on October 10, 2017. On March 2, 2018, the Texas Supreme Court ruled in favor of EXLP Leasing and EES Leasing by reversing the Fourteenth Court of Appeals’ decision. In doing so, the Supreme Court upheld the validity of the Heavy Equipment Rules and held that compressors are taxable in the county of EXLP Leasing’s and EES Leasing’s business location, not where each compressor is located on January 1. On March 8, 2018, the Galveston Central Appraisal District filed a motion for extension of time to file a motion for rehearing. The Court granted the motion and Galveston Central Appraisal District filed the motion for rehearing on April 2, 2018.

We continue to believe that the revised statutes are constitutional as applied to natural gas compressors and that under the revised statutes our natural gas compressors are taxable in the counties where we maintain a business location and keep natural gas compressors. Recognizing the similarity of the issues and that these cases will ultimately be resolved by the Texas appellate courts, most of the remaining 2012-2017 district court cases have been formally or effectively abated pending final judgment from the Texas Supreme Court.

If we are unsuccessful in our litigation, we would be required to pay ad valorem taxes up to the aggregate benefit we have recorded, and the additional ad valorem tax payments may also be subject to substantial penalties and interest. In addition, while we do not expect the ultimate determination of the issue of where the natural gas compressors are taxable under the Heavy Equipment Statutes would have an impact on the amount of taxes due, we could be subject to substantial penalties if we are unsuccessful on this issue. Also, if we are unsuccessful in our litigation, or if legislation is enacted in Texas that repeals or alters the Heavy Equipment Statutes such that in the future we do not qualify as a Heavy Equipment Dealer or our compressors do not qualify as Heavy Equipment, then we would likely be required to pay these ad valorem taxes under the old methodology going forward, which would increase our quarterly cost of sales expense up to approximately the amount of our then most recent quarterly benefit recorded. If this litigation is resolved against us in whole or in part, or if in the future we do not qualify as a Heavy Equipment Dealer or our compressors do not qualify as Heavy Equipment because of new or revised Texas statutes, we will incur additional taxes and could be subject to substantial penalties and interest, which would impact our future results of operations, financial position and cash flows, including our ability to pay dividends.

Table of Contents

In the ordinary course of business, we are also involved in various other 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 other 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.

In addition, the SEC has been conducting an investigation in connection with certain previously disclosed errors and possible irregularities at one of our former international operations. We and Exterran Corporation are cooperating with the SEC in the investigation, which has included, among other things, responding to subpoenas for documents and testimony related to the restatement of prior period consolidated and combined financial statements and related disclosures and compliance with the FCPA, which were also being provided to the DOJ at its request. The SEC staff has provided notice that they have concluded their investigation relating to compliance with the FCPA and that they do not intend to recommend an enforcement action concerning compliance with the FCPA, and the Department of Justice has also provided notice that it does not intend to proceed with any further investigation or enforcement.

16. Segments

We manage our business segments primarily based upon 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 other financial information by segment during the three months ended March 31, 2018 and 2017 (in thousands):



	Contract Operations		Aftermarket Services		Segments Total

17. Transactions Related to the Partnership

On April 26, 2018, we completed the acquisition of all of the outstanding common units of the Partnership at a fixed exchange ratio of 1.40 shares of our common stock for each common unit of the Partnership not owned by us. Additionally, the incentive distribution rights in the Partnership, which were previously owned indirectly by us, were canceled and ceased to exist. As a result of the Merger, common units of the Partnership are no longer publicly traded. See Note 18 (“Subsequent Events”) for further details of this transaction.

At March 31, 2018, we owned an approximate 43% interest in the Partnership and the Partnership’s fleet included 5,989 compressor units comprising 3.3 million horsepower, or 86%, of our and the Partnership’s combined total horsepower.

The liabilities recognized as a result of consolidating the Partnership do not necessarily represent additional claims on our general assets outside of the Partnership; rather, they represent claims against the specific assets of the Partnership. Conversely, assets recognized as a result of consolidating the Partnership do not necessarily represent additional assets that could be used to satisfy claims against our general assets. There are no restrictions on the Partnership’s assets that are reported in our general assets.

On April 30, 2018, the board of directors of Archrock GP LLC, the general partner of the General Partner, approved a cash distribution by the Partnership of approximately $15.5 million. The distribution covers the period from January 1, 2018 through March 31, 2018. Any distributions in respect of the Partnership’s common units will be paid to us as the owner of all outstanding common units.

During the three months ended March 31, 2018 and March 31, 2017, the Partnership issued and sold to the General Partner 690 and 1,119 general partner units, respectively, to maintain the General Partner’s approximate 2% general partner interest in the Partnership.

18. Subsequent Events

Merger Transaction

On January 1, 2018, we entered into the Merger Agreement pursuant to which we agreed to merge the Partnership into our indirect wholly-owned subsidiary. On April 26, 2018, the Merger was completed and we acquired the 41.2 million common units of the Partnership not owned by us at a fixed exchange ratio of 1.40 shares of our common stock for each Partnership common unit for total implied consideration of approximately $625.3 million. In addition, all of the Partnership’s incentive distribution rights, which were owned indirectly by us, were canceled and ceased to exist. As a result of the completion of the Merger, common units of the Partnership are no longer publicly traded.

Table of Contents

As we controlled the Partnership prior to the Merger and continue to control the Partnership after the Merger, the change in our ownership interest will be accounted for as an equity transaction, and no gain or loss will be recognized in our condensed consolidated statements of operations resulting from the Merger. The tax effects of the Merger will be reported as adjustments to long-term assets associated with discontinued operations, deferred income taxes, additional paid-in capital and other comprehensive income.

Amendment to the Partnership Credit Facility and Termination of the Archrock Credit Facility

On February 23, 2018, the Partnership amended the Partnership Credit Facility to, among other things:


•	increase the maximum Total Debt to EBITDA ratio (as defined in the Partnership Credit Facility agreement), effective as of the execution of Amendment No. 1 on February 23, 2018; and


•	effective upon completion of the Merger on April 26, 2018:


–	increase the aggregate revolving commitment to $1.25 billion;


–	increase the amount available for incremental increases to the commitments under the Partnership Credit Facility to $500.0 million;


–	increase the amount available for the issuance of letters of credit to $50.0 million;


–	increase the basket sizes under certain covenants including covenants limiting our ability to make investments, incur debt, make restricted payments, incur liens and make asset dispositions;


–	name Archrock Services, L.P., one of our subsidiaries, as a borrower under the Partnership Credit Facility and certain of our other subsidiaries as loan guarantors; and


–	amend the definition of “Borrowing Base” to include certain assets of ours and our subsidiaries.

On April 26, 2018, in connection with the Merger and Amendment No. 1, we also terminated the Archrock Credit Facility and repaid $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 as of the Merger were converted to letters of credit under the Partnership Credit Facility.

Overview

We are a pure play U.S. natural gas contract operations services business and 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 primary business segments: contract operations and aftermarket services. In our contract operations business, we use our owned fleet of natural gas compression equipment to provide operations 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.

Archrock Partners, L.P.

The Partnership is a master limited partnership that provides natural gas contract operations services to customers throughout the U.S. As of March 31, 2018, prior to the closing of the Merger, public unitholders held an approximate 57% ownership interest in the Partnership and we owned the remaining equity interest, including all of the general partner interest and incentive distribution rights. As a result of the closing of the Merger, the Partnership is our indirect wholly-owned subsidiary and the incentive distribution rights in the Partnership were canceled. We consolidate the financial position and results of operations of the Partnership.

Merger Transaction

Amendment to the Partnership Credit Facility

On February 23, 2018, the Partnership amended the Partnership Credit Facility to, among other things, increase the maximum Total Debt to EBITDA ratio. In addition, on April 26, 2018, concurrent with the Merger and certain terms within Amendment No. 1, the Partnership increased the aggregate revolving commitment under the Partnership Credit Facility to $1.25 billion and we terminated the Archrock Credit Facility and all commitments under that facility. See “Liquidity and Capital Resources - Financial Resources” below and Notes 8 (“Long-Term Debt”) and 18 (“Subsequent Events”) to the Financial Statements for further discussion of Amendment No. 1.

Trends and Outlook

Our business environment and corresponding operating results are affected by the level of energy industry spending for the exploration, development and production of oil and natural gas reserves in the U.S. Spending by oil and natural gas exploration and production companies is dependent upon these companies’ forecasts regarding the expected future supply, demand and pricing of oil and natural gas products as well as their estimates of risk-adjusted costs to find, develop and produce reserves. For example, oil and natural gas exploration and development activity and the number of well completions typically decline when there is a significant reduction in oil and natural gas prices or significant instability in energy markets. Our revenue, earnings and financial position are affected by, among other things, market conditions that impact demand and pricing for natural gas compression, our customers’ decisions between using our services or our competitors’ services, our customers’ decisions regarding whether to own and operate the equipment themselves and the timing and consummation of any acquisition of additional contract operations customer service agreements and equipment from third parties. Although our contract operations business is typically less impacted by commodity prices than certain other oil and natural gas service providers, changes in oil and natural gas exploration and production spending normally result in changes in demand for our services.

Natural gas consumption in the U.S. for the twelve months ended January 31, 2018 remained flat at 27,509 Bcf compared to 27,293 Bcf for the twelve months ended January 31, 2017. The EIA forecasts that total U.S. natural gas consumption will increase 6% in 2018 compared to 2017. The EIA estimates that the U.S. natural gas consumption level will be approximately 32 Tcf in 2040, or 18% of the projected worldwide total of approximately 177 Tcf.

Natural gas marketed production in the U.S. for the twelve months ended January 31, 2018 increased 2% to 29,041 Bcf compared to 28,376 Bcf for the twelve months ended January 31, 2017. The EIA forecasts that total U.S. natural gas marketed production will increase 10% in 2018 compared to 2017. The EIA estimates that the U.S. natural gas production level will be approximately 38 Tcf in 2040, or 21% of the projected worldwide total of approximately 177 Tcf.

Historically, oil and natural gas prices and the level of drilling and exploration activity in the U.S. have been volatile. The average price for natural gas, based on daily Henry Hub spot prices, in the first quarter of 2018 was 3% and 2% higher than the average price in the full year 2017 and first quarter of 2017, respectively, despite the spot price at March 29, 2018 being 24% and 10% lower than the spot price at December 29, 2017 and March 31, 2017, respectively. The U.S. natural gas liquid composite price was 17% higher in January 2018 than in January 2017, and the average price in the twelve months ended January 31, 2018 was 32% higher than the average price in the twelve months ended January 31, 2017. The West Texas Intermediate crude oil spot price at March 29, 2018 was 7% and 28% higher than at December 29, 2017 and March 31, 2017, respectively, and the average crude oil price in the first quarter of 2018 was 24% and 22% higher than the average price in the full year 2017 and first quarter of 2017, respectively.

Table of Contents

Increased stability of oil and natural gas prices in 2017 contributed to increased new orders for our compression services in 2017 and thus far in 2018. Additionally, we increased our investment in new fleet units in 2017 and thus far in 2018 to take advantage of improved market conditions during 2017. As a result of these increased orders and investment, our contract operations revenue and average operating horsepower increased 7% and 6%, respectively, in the three months ended March 31, 2018 compared to the three months ended March 31, 2017. Our aftermarket services business also benefited from improved market conditions and continued the recovery begun in 2017 into 2018 with a 27% increase in revenue in the three months ended March 31, 2018 compared to the three months ended March 31, 2017.

According to the Barclays 2018 Global E&P Spending Outlook, North America upstream spending is expected to increase by 21% in 2018. Due to this forecasted increase in customer spending in 2018 and the significant increase in new orders for compression services and investment in new fleet units in 2017 and thus far into 2018, we anticipate an increase in average operating horsepower during 2018 compared to 2017 as well as increased revenue in our contract operations and aftermarket services businesses.

According to Drillinginfo, natural gas production is expected to increase approximately 18% through 2022, with further increases anticipated beyond then. We believe that significantly improved quantities, accessibility and price stability of natural gas in the U.S. will continue to drive higher levels of demand for liquid natural gas export, pipeline exports to Mexico, power generation and use as a petrochemical feedstock, which will in turn lead to a significant increase in demand for compression services.

Non-GAAP Financial Measures

Our 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. 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 another company because other entities may not calculate gross margin in the same manner.

Table of Contents

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 interest expense, depreciation and amortization, SG&A, impairments, restatement and other charges, restructuring and other charges, debt extinguishment costs, provision for (benefit from) income taxes and other (income) loss, net. 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 $212.0 million and $189.9 million during the three months ended March 31, 2018 and 2017, respectively. The increase in revenue during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was due to increases in revenue from our contract operations and aftermarket services businesses. See “Contract Operations” and “Aftermarket Services” below for further details.

Net loss attributable to Archrock stockholders. Net loss attributable to Archrock stockholders was $3.8 million and $11.7 million during the three months ended March 31, 2018 and 2017, respectively. The decrease in net loss attributable to Archrock stockholders during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily driven by the increase in gross margin from our contract operations and aftermarket services businesses and decreases in long-lived asset impairment and depreciation and amortization, partially offset by Merger-related costs and the change in net income (loss) attributable to the noncontrolling interest.

⁽¹⁾	Defined as gross margin divided by revenue.

The increase in revenue during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to a 6% increase in average operating horsepower and an increase in rates resulting from an increase in customer demand driven by improved market conditions in 2017. The increase in revenue was partially offset by the deferral of rebillable freight revenue as a result of the adoption of the Revenue Recognition Update.

Gross margin increased during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 primarily due to the increase in revenue mentioned above. Cost of sales remained flat due to the capitalization of freight and mobilization costs incurred to fulfill contracts prior to the transfer of service as a result of the adoption of the Revenue Recognition Update, which offset increases in costs associated with the increase in average operating horsepower, the mobilization of compressor units, freight expense and other operating costs of providing our contract operations services. Gross margin percentage increased during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 primarily due to the capitalization of costs incurred to fulfill contracts prior to the transfer of service as a result of the adoption of the Revenue Recognition Update.

The increase in revenue during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to increases in service and part sales activities as well as the change to recognize revenue for service activities over time as a result of the adoption of the Revenue Recognition Update.

Gross margin increased during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 primarily due to the increase in revenue mentioned above, partially offset by the increase in cost of sales that was mainly driven by the increase in service and part sales activities as well as the change to recognize costs associated with service activities over time as a result of the adoption of the Revenue Recognition Update. Gross margin percentage increased during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 primarily due to higher utilization rates as a result of the increase in activity mentioned above.

Depreciation and amortization. The decrease in depreciation and amortization expense during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to 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 2017, partially offset by an increase in depreciation expense associated with fixed asset additions.

Long-lived asset impairment. During the three months ended March 31, 2018 and 2017, 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 (dollars in thousands):



	Three Months Ended March 31,
	2018		2017
Idle compressor units retired from the active fleet	45		80
Horsepower of idle compressor units retired from the active fleet	22,000		28,000
Impairment recorded on idle compressor units retired from the active fleet	$	4,710	$	8,245

Restatement and other charges. During the three months ended March 31, 2018 and 2017, we incurred $0.5 million and $0.8 million, respectively, of restatement and other charges primarily for professional and legal fees related to the restatement of prior period consolidated and combined financial statements and related disclosures and related matters described in Note 15 (“Commitments and Contingencies”) to our Financial Statements.

Restructuring and other charges. As discussed in Note 4 (“Discontinued Operations”) to our Financial Statements, we completed the Spin-off in 2015. During the three months ended March 31, 2017 we incurred $0.5 million of costs associated with the Spin-off which were directly attributable to Archrock. These charges are reflected as restructuring and other charges in our condensed consolidated statement of operations. No additional costs were incurred under this program subsequent to the year ended December 31, 2017.

Interest expense. The increase in interest expense during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to an increase in the weighted average effective interest rate partially offset by a $0.6 million write-off of deferred financing costs associated with the termination of the Former Credit Facility in the three months ended March 31, 2017.

Merger-related costs. We incurred $4.1 million of Merger-related costs consisting of financial advisory, legal and other professional fees during the three months ended March 31, 2018.

Table of Contents

Other income, net. The increase in other income, net during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to a $0.4 million increase in gain on sale of property, plant and equipment.

Income Taxes

(dollars in thousands)



	Three Months Ended March 31,						Increase
	2018			2017			(Decrease)
Provision for income taxes	$	354		$	323		10	%
Effective tax rate	15		%	(2		)%	17	%

The increase in provision for income taxes during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to an increase in book income tax effected at the lower corporate income tax rate in 2018 as the result of the TCJA, offset almost entirely by a lower unrecognized tax benefit recorded in 2018 compared to 2017.

Net Income (Loss) Attributable to the Noncontrolling Interest

(dollars in thousands)



	Three Months Ended March 31,					Increase
	2018			2017		(Decrease)
Net (income) loss attributable to the noncontrolling interest	$	(5,885	)	$	2,328	(353	)%

The noncontrolling interest comprises the portion of the Partnership’s earnings that are applicable to the Partnership’s publicly-held common unitholder interest. As of March 31, 2018 and 2017, public unitholders held an ownership interest in the Partnership of 57% and 55%, respectively. The change in net (income) loss attributable to the noncontrolling interest during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to the change in net income (loss) of the Partnership. The change in net income (loss) of the Partnership was primarily due to the increase in revenue and decreases in long-lived asset impairment and depreciation and amortization.

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 our Archrock Credit Facility and the Partnership Credit Facility. On April 26, 2018, in connection with the closing of the Merger and Amendment No. 1, the aggregate revolving commitment of the Partnership Credit Facility was increased from $1.1 billion to $1.25 billion and the Archrock Credit Facility was terminated. See “Financial Resources” below and Notes 8 (“Long-Term Debt”) and 18 (“Subsequent Events”) to the Financial Statements for further details.

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. New orders for compression services were strong in 2017 and we have continued to book new orders at elevated rates into 2018. We believe that our operating cash flows and borrowings under the Partnership Credit Facility will be sufficient to meet our liquidity needs through at least March 31, 2019.

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.

Table of Contents

Capital Requirements

The natural gas compression 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 render 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 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.

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, 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 $300 million to $320 million in capital expenditures during 2018, primarily consisting of $230 million to $250 million for growth capital expenditures and $40 million to $45 million for maintenance capital expenditures.

⁽²⁾	The amounts for the three months ended March 31, 2018 pertain to the Partnership Credit Facility. The amounts for the three months ended March 31, 2017 pertain to the Partnership’s Former Credit Facility.

Archrock Credit Facility. On April 26, 2018, in connection with the Merger and Amendment No. 1, we terminated the Archrock Credit Facility and repaid $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 as of the Merger were converted to letters of credit under the Partnership Credit Facility.

Table of Contents

Prior to its termination, the Archrock Credit Facility required us to maintain the following consolidated financial ratios, as defined in the Archrock Credit Facility agreement:



EBITDA to Total Interest Expense	2.25 to 1.0
Total Debt to EBITDA ⁽¹⁾	4.25 to 1.0

——————


⁽¹⁾	Subject to a temporary increase to 4.75 to 1.0 for any quarter during which an acquisition meeting certain thresholds is completed and for the following two quarters after the quarter in which the acquisition closes.

As a result of the Total Debt to EBITDA ratio limitation above, $224.2 million of the $282.1 million undrawn capacity under the Archrock Credit Facility was available for additional borrowings as of March 31, 2018.

The Archrock Credit Facility contained various additional covenants with which we were required to comply, including, but not limited to, limitations on the incurrence of indebtedness, investments, liens on assets, repurchasing equity and making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. As of March 31, 2018, we were in compliance with all covenants under the Archrock Credit Facility.

Partnership Credit Facility. On February 23, 2018, the Partnership amended the Partnership Credit Facility to, among other things:


•	increase the maximum Total Debt to EBITDA ratio (as defined in the Partnership Credit Facility agreement), effective as of the execution of Amendment No. 1 on February 23, 2018; and


•	effective upon the closing of the Merger:


–	increase the aggregate revolving commitment to $1.25 billion;.


–	increase the amount available for incremental increases to the commitments under the Partnership Credit Facility to $500.0 million;


–	increase the amount available for the issuance of letters of credit to $50.0 million;


–	increase the basket sizes under certain covenants including covenants limiting our ability to make investments, incur debt, make restricted payments, incur liens and make asset dispositions;


–	name Archrock Services, L.P., one of our subsidiaries, as a borrower under the Partnership Credit Facility and certain of our other subsidiaries as loan guarantors; and


–	amend the definition of “Borrowing Base” to include certain assets of ours and our subsidiaries.

The Partnership Credit Facility matures on March 30, 2022, except that if any portion of the Partnership’s 6% senior notes due April 2021 are outstanding as of December 2, 2020, then maturity will instead be on December 2, 2020. Portions of the Partnership Credit Facility up to $50.0 million are available for the issuance of swing line loans. The Partnership Credit Facility borrowing base consists of eligible accounts receivable, inventory and compressor units.

The Partnership must maintain the following consolidated financial ratios, as defined in the Partnership 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 2018	5.95 to 1.0
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 meeting certain thresholds is completed and for the following two quarters after the quarter in which the acquisition closes.

As a result of the Total Debt to EBITDA ratio limitation above, $177.2 million of the $413.0 million undrawn capacity under the Partnership Credit Facility was available for additional borrowings as of March 31, 2018.

Table of Contents

The Partnership 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 the Partnership’s 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 the Partnership has 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 Partnership 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 Partnership Credit Facility. As of March 31, 2018, the Partnership was in compliance with all covenants under the Partnership Credit Facility.

Other

In connection with the Spin-off, we entered into a separation and distribution agreement with Exterran Corporation pursuant to which we have the right to receive payments from a subsidiary of Exterran Corporation based on a notional amount corresponding to payments received by Exterran Corporation’s subsidiaries from PDVSA Gas in respect of the sale of Exterran Corporation’s subsidiaries’ and joint ventures’ previously nationalized assets. As of March 31, 2018, Exterran Corporation was due to receive the remaining principal amount of $20.9 million from PDVSA Gas.

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):



	Three Months Ended March 31,
	2018			2017
Net cash provided by (used in) continuing operations:
Operating activities	$	62,455		$	54,742
Investing activities	(54,991		)	(25,149		)
Financing activities	(14,443		)	(21,965		)
Discontinued operations	—			45
Net change in cash and cash equivalents	$	(6,979	)	$	7,673

Operating Activities. The increase in net cash provided by operating activities from continuing operations during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to an increase in revenues in our contract operations and aftermarket services segments primarily driven by improved market conditions and an increase in accounts payable as a result of timing of payments to vendors. These activities were partially offset by an increase in cost of sales, including freight and mobilization costs incurred to fulfill contracts prior to the transfer of service, an increase in merger related costs and an increase in accounts receivable as a result of the timing of payments received from our customers.

Investing Activities. The increase in net cash used in investing activities from continuing operations during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to a $39.1 million increase in capital expenditures, partially offset by a $9.1 million increase in proceeds from sale of property, plant and equipment.

Financing Activities. The decrease in net cash used in financing activities from continuing operations during the three months ended March 31, 2018 compared to the three months ended March 31, 2017 was primarily due to $9.2 million net borrowings of long-term debt during the three months ended March 31, 2018 compared to $6.5 million net repayments during the three months ended March 31, 2017 and a $12.1 million decrease in payments for debt issuance costs. These changes were partially offset by a $19.7 million decrease in contributions from Exterran Corporation.

Dividends

On April 25, 2018, our board of directors declared a quarterly dividend of $0.12 per share of common stock to be paid on May 15, 2018 to stockholders of record at the close of business on May 8, 2018. 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 and results of operations, credit and loan agreements in effect at that time and other factors deemed relevant by our board of directors.

Partnership Distributions to Unitholders

The Partnership’s partnership agreement requires it to distribute all of its “available cash” quarterly. Under the partnership agreement, available cash is defined generally to mean, for each fiscal quarter, (i) cash on hand at the Partnership at the end of the quarter in excess of the amount of reserves its General Partner determines is necessary or appropriate to provide for the conduct of its business, to comply with applicable law, any of its debt instruments or other agreements or to provide for future distributions to its unitholders for any one or more of the upcoming four quarters, plus, (ii) if the General Partner so determines, all or a portion of the Partnership’s cash on hand on the date of determination of available cash for the quarter.

Through our ownership of all of the equity interests in the Partnership post-Merger, we expect to receive cash distributions from the Partnership.

Under the terms of the partnership agreement, there is no guarantee that unitholders will receive quarterly distributions from the Partnership. The Partnership’s distribution policy, which may be changed at any time, is subject to certain restrictions, including (i) restrictions contained in the Partnership’s Credit Facility, (ii) the General Partner’s establishment of reserves to fund future operations or cash distributions to the Partnership’s unitholders, (iii) restrictions contained in the Delaware Revised Uniform Limited Partnership Act and (iv) the Partnership’s lack of sufficient cash to pay distributions.

Off-Balance Sheet Arrangements

For information on our obligations with respect to performance bonds and letters of credit, see Note 15 (“Commitments and Contingencies”) and Note 8 (“Long-Term Debt”), respectively, to our Financial Statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk primarily associated with changes in interest rates under our financing arrangements. We use derivative instruments to minimize the risks and costs associated with financial activities by managing our exposure to interest rate fluctuations on a portion of our debt obligations. We do not use derivative instruments for trading or other speculative purposes.

As of March 31, 2018, after taking into consideration interest rate swaps, we had $239.5 million of outstanding indebtedness that was effectively subject to floating interest rates. A 1% increase in the effective interest rate on our outstanding debt subject to floating interest rates at March 31, 2018 would result in an annual increase in our interest expense of $2.4 million.

For further information regarding our use of interest rate swaps to manage our exposure to interest rate fluctuations on a portion of our debt obligations, see Note 9 (“Derivatives”) to our Financial Statements.

Item 4. Controls and Procedures

This Item 4 includes information concerning the controls and controls evaluation referred to in the certifications of our Chief Executive Officer and Chief Financial Officer required by Rule 13a-14 of the Exchange Act included in this Quarterly Report as Exhibits 31.1 and 31.2.
