CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (the “Quarterly Report”) includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements, other than statements of historical fact included in this Quarterly Report, regarding our strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this Quarterly Report, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” “preliminary,” “forecast,” and similar expressions or variations are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on our current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements described under the heading “Risk Factors” included in our most recent Annual Report on Form 10-K and under the heading “Part II―Item 1A. Risk Factors” in this Quarterly Report. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events.

Important factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to, those summarized below:

| ● | the level of capital spending and access to capital markets by oil and gas companies;

| ● | trends and volatility in oil and gas prices;

| ● | demand for our services;

| ● | capacity constraints on regional oil, natural gas and water gathering, processing and pipeline systems that result in a slowdown or delay in drilling and completion activity, and thus a slowdown or delay in the demand for our services in our core markets;

| ● | our ability to retain key management and employees;

| ● | our ability to hire and retain skilled labor;

| ● | regional impacts to our business, including our key infrastructure assets within the Bakken and northern Delaware formation of the Permian Basin;

| ● | our access to capital to fund expansions, acquisitions and our working capital needs and our ability to obtain debt or equity financing on satisfactory terms;

| ● | our health, safety and environmental performance;

| ● | the impact of current and future laws, rulings and governmental regulations, including those related to hydraulic fracturing, accessing water, disposing of wastewater, transferring produced water, interstate freshwater transfer, chemicals and various environmental matters;

| ● | the impact of competition on our operations;

| ● | the degree to which our exploration and production (“E&P”) customers may elect to bring their water-management services in-house rather than source these services from companies like us;

| ● | our level of indebtedness and our ability to comply with covenants contained in our Credit Agreement (as defined herein) or future debt instruments;

3

Table of Contents

| ● | delays or restrictions in obtaining permits by us or our customers;

| ● | constraints in supply or availability of equipment used in our business;

| ● | the impact of advances or changes in well-completion technologies or practices that result in reduced demand for our services, either on a volumetric or time basis;

| ● | changes in global political or economic conditions, generally, and in the markets we serve;

| ● | accidents, weather, seasonality or other events affecting our business; and

| ● | the other risks identified in our most recent Annual Report on Form 10-K, and under the headings “Part I―Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Part II―Item 1A. Risk Factors” in this Quarterly Report.

These factors are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could have material adverse effects on our future results. Our future results will depend upon various other risks and uncertainties, including those described under the heading “Part I―Item 1A. Risk Factors” in our most recent Annual Report on Form 10-K and under the heading “Part II―Item 1A. Risk Factors” in this Quarterly Report. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date hereof. We undertake no obligation to update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise. All forward-looking statements attributable to us are qualified in their entirety by this cautionary note.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

NOTE 1—BUSINESS AND BASIS OF PRESENTATION

Description of the business: Select Energy Services, Inc. (“we,” “Select Inc.” or the “Company”) was incorporated as a Delaware corporation on November 21, 2016. The Company is a holding company whose sole material asset consists of common units (“SES Holdings LLC Units”) in SES Holdings, LLC (“SES Holdings” or the “Predecessor”).

We are a leading provider of water-management solutions to the oil and gas industry in the United States (“U.S.”). We also develop, manufacture and deliver chemical solutions for use in oil and gas well completions and production operations. Within the major shale plays in the U.S., we believe we are a market leader in water sourcing, water transfer (both by permanent pipeline and temporary hose) and temporary water containment prior to its use in drilling and completion activities associated with hydraulic fracture stimulation or “fracking,” which we refer to collectively as “pre-frac water services”. In addition, we provide testing and flowback services immediately following the well completion. In most of our areas of operations, we also provide additional complementary water-related services that support oil and gas well completion and production activities, including water network automation, treatment, hauling, water recycling and disposal. We also manufacture a full suite of specialty chemicals used in the fracturing process, and we provide chemicals needed by our customers to help increase oil and gas production and lower costs over the life of a well. We believe we are the only company in the oilfield services industry that combines full life cycle water-management services with the ability to develop and provide related chemical products.

Select 144A Offering and Initial Public Offering. On December 20, 2016, Select Inc. completed a private placement (the “Select 144A Offering”) of 16,100,000 shares of Select Inc. Class A-1 common stock, par value $0.01 per share, which were converted into shares of Class A common stock, par value $0.01 per share (“Class A Common Stock”) following the Company’s initial public offering (“IPO”). SES Holdings issued 16,100,000 SES Holdings LLC Units to Select Inc., and Select Inc. became the sole managing member of SES Holdings. Select Inc. issued 38,462,541 shares of its Class B common stock, par value $0.01 per share (“Class B Common Stock”), to the other member of SES Holdings, SES Legacy Holdings, LLC (“Legacy Owner Holdco”) or one share for each SES Holdings LLC Unit held by Legacy Owner Holdco. On April 26, 2017, the Company completed its IPO of 8,700,000 shares of Class A Common Stock. Shareholders of Class A Common Stock and Class B Common Stock vote together as a single class on all matters, subject to certain exceptions in the Company’s amended and restated certificate of incorporation. Holders of Class B Common Stock have voting rights only and are not entitled to an economic interest in Select Inc. based on their ownership of Class B Common Stock.

Tax Receivable Agreements: In connection with the Company’s restructuring at the Select 144A Offering, Select Inc. entered into two tax receivable agreements (the “Tax Receivable Agreements”) with Legacy Owner Holdco and certain other affiliates of the then-holders of SES Holdings LLC Units (each such person and any permitted transferee thereof, a “TRA Holder,” and together, the “TRA Holders”). On July 18, 2017, the Company’s board of directors approved amendments to each of the Tax Receivable Agreements. See Note 13—Related Party Transactions for further discussion.

Exchange rights: Under the Eighth Amended and Restated Limited Liability Company Agreement of SES Holdings (the “SES Holdings LLC Agreement”), Legacy Owner Holdco and its permitted transferees have the right (an “Exchange Right”) to cause SES Holdings to acquire all or a portion of its SES Holdings LLC Units for, at SES Holdings’ election, (i) shares of Class A Common Stock at an exchange ratio of one share of Class A Common Stock for each SES Holdings LLC Unit exchanged, subject to conversion rate adjustments for stock splits, stock dividends, reclassification and other similar transactions or (ii) cash in an amount equal to the Cash Election Value (as defined within the SES Holdings LLC Agreement) of such Class A Common Stock. Alternatively, upon the exercise of any Exchange Right, Select Inc. has the right (the “Call Right”) to acquire the tendered SES Holdings LLC Units from the exchanging unitholder for, at its election, (i) the number of shares of Class A Common Stock the exchanging unitholder would have received under the Exchange Right or (ii) cash in an amount equal to the Cash Election Value of such Class

A Common Stock. In connection with any exchange of SES Holdings LLC Units pursuant to an Exchange Right or Call Right, the corresponding number of shares of Class B Common Stock will be cancelled.

2017 Business Combinations: The Company completed three business combinations during 2017 that significantly increased its size. On March 10, 2017, the Company completed the acquisition of Gregory Rockhouse Ranch, Inc. (the “GRR Acquisition”) and certain other affiliated entities and assets (collectively, the “GRR Entities”) for consideration of $59.6 million. On September 15, 2017, the Company completed the acquisition (the “Resource Water Acquisition”) of Resource Water Transfer Services, L.P. and certain other affiliated assets (collectively, “Resource Water”) for $9.0 million. Additionally, on November 1, 2017, the Company completed its merger (the “Rockwater Merger”) with Rockwater Energy Solutions, Inc. (“Rockwater”) in which the Company combined with Rockwater for total consideration of $620.2 million.

Basis of presentation: The accompanying unaudited interim consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). These unaudited interim consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all disclosures required for financial statements prepared in conformity with GAAP.

This Form 10-Q relates to the three and six months ended June 30, 2019 (the “Current Quarter” and the “Current Period”, respectively) and the three and six months ended June 30, 2018 (the “Prior Quarter” and the “Prior Period”, respectively). The Company’s annual report on Form 10-K for the year ended December 31, 2018 (the “2018 Form 10-K”) filed with the SEC on March 1, 2019, includes certain definitions and a summary of significant accounting policies and should be read in conjunction with this Form 10-Q. All material adjustments (consisting solely of normal recurring adjustments) which, in the opinion of management, are necessary for a fair statement of the results for the interim periods have been reflected. The results for the Current Quarter and Current Period are not necessarily indicative of the results to be expected for the full year.

The unaudited interim consolidated financial statements include the accounts of the Company and all of its majority-owned or controlled subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

For investments in subsidiaries that are not wholly owned, but where the Company exercises control, the equity held by the minority owners and their portion of net income or loss are reflected as noncontrolling interests. Investments in entities for which the Company does not have significant control or influence are accounted for using the cost method. As of June 30, 2019, the Company had one cost-method investee. The Company’s investments are reviewed for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. When circumstances indicate that the fair value of its investment is less than its carrying value and the reduction in value is other than temporary, the reduction in value is recognized in earnings.

Segment reporting: The Company has three operating and reportable segments. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance. The Company’s current reportable segments are Water Services, Water Infrastructure, and Oilfield Chemicals, following its decision in the first quarter of 2019 to sell and wind down certain operations within its former Wellsite Services segment, including the operations of its subsidiary Affirm Oilfield Services, LLC (“Affirm”), and its sand hauling and Canadian operations.

Table of Contents

The Water Services segment consists of the Company’s services businesses including water transfer, flowback and well testing, fluids hauling, containment, and water treatment and water network automation, primarily serving E&P companies. Additionally, this segment includes the operations of our accommodations and rentals business, which were previously a part of the former Wellsite Services segment.

The Water Infrastructure segment consists of the Company’s infrastructure assets and ongoing infrastructure development projects, including operations associated with our water sourcing and pipelines, produced water gathering systems and salt water disposal wells, primarily serving E&P companies.

The Oilfield Chemicals segment develops, manufactures and provides a full suite of chemicals used in hydraulic fracturing, stimulation, cementing and well completions, including polymer slurries, crosslinkers, friction reducers, buffers breakers and other chemical technologies, to leading pressure pumping service companies in the United States.

The results of our remaining service lines that were previously a part of the former Wellsite Services segment including the operations of our Affirm subsidiary, our sand hauling operations and our Canadian operations are combined in the “Other” category.

The unaudited interim consolidated financial statements in this report reflect our new segment structure, and the statements of operations, statements of comprehensive income and statements of cash flows for the three and six months ended June 30, 2018 have been restated to reflect our new segment structure.

Reclassifications: Certain reclassifications have been made to the Company’s prior period consolidated financial information in order to conform to the current period presentation. These presentation changes did not impact the Company’s consolidated net income, consolidated cash flows, total assets, total liabilities or total stockholders’ equity.

NOTE 2—SIGNIFICANT ACCOUNTING POLICIES

Significant accounting policies: The Company’s significant accounting policies are disclosed in Note 2 of the consolidated financial statements for the year ended December 31, 2018, included in the Company’s most recent Annual Report on Form 10-K. With the exception of the adoption of the new lease standard discussed in Note 5, there have been no significant changes in such policies or the application of such policies during the Current Quarter.

Use of estimates: The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

On an ongoing basis, the Company evaluates its estimates, including those related to the recoverability of long-lived assets and intangibles, useful lives used in depreciation and amortization, uncollectible accounts receivable, inventory, income taxes, self-insurance liabilities, share-based compensation, contingent liabilities and the incremental borrowing rate for leases. The Company bases its estimates on historical and other pertinent information that are believed to be reasonable under the circumstances. The accounting estimates used in the preparation of the consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes.

We review the adequacy of our ARO liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed. The Company’s ARO liabilities are included in accrued expenses and other current liabilities and other long-term liabilities in the accompanying consolidated balance sheets.

Recent accounting pronouncements: In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases, which modifies the lease recognition requirements and requires entities to recognize the assets and liabilities arising from leases on the balance sheet and to disclose key qualitative and quantitative information about the entity’s leasing arrangements. Based on the original guidance in ASU 2016-02, lessees and lessors would have been required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach, including a number of optional practical expedients. In July 2018, the FASB issued ASU No. 2018-11, Leases (ASC 842): Targeted Improvements, which provides entities with an option to apply the guidance prospectively, instead of retrospectively, and allows for other classification provisions. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2016-02 in the first quarter of 2019. The Company elected to recognize its lease assets and liabilities on a prospective basis, beginning on January 1, 2019, using the modified retrospective transition method. Additionally, the Company elected practical expedients to (i) exclude right-of-use assets and lease liabilities for short-term leases, (ii) elected to treat lease and non-lease components as a single lease component, (iii) grandfathered its current accounting for land easements that commenced before January 1, 2019, and (iv) used the package of practical expedients to retain prior lease classification, prior treatment of initial direct costs and prior determination of whether a contract constituted a lease. See Note 5—Leases for additional information.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends U.S. GAAP by introducing a new impairment model for financial instruments that is based on expected credit losses rather than incurred credit losses. The new impairment model applies to most financial assets, including trade accounts receivable. The amendments are effective for interim and annual reporting periods beginning after December 15, 2019, although it may be adopted one year earlier, and requires a modified retrospective transition approach. This will mainly impact the Company’s trade receivables allowance calculation. The Company is assessing the best approach to estimate allowances and is evaluating the impact this standard will have on its consolidated financial statements.

NOTE 3—ACQUISITIONS AND DIVESTITURES

Business combinations

Pro Well Acquisition

On November 20, 2018, the Company acquired Pro Well Testing and Wireline, Inc. with an initial payment of $12.4 million, funded with cash on hand (the “Pro Well Acquisition”). During March 2019, upon final settlement, the purchase price was revised to $11.8 million.

This acquisition expanded the Company’s flowback footprint into New Mexico and added new strategic customers. The Pro Well Acquisition was accounted for as a business combination under the acquisition method of accounting. When determining the fair values of assets acquired and liabilities assumed, management made significant estimates, judgments and assumptions. Management estimated that total consideration paid exceeded the fair value of the net assets acquired by $1.1 million, with the excess recorded as goodwill. The goodwill recognized was primarily attributable to expanding the Company’s flowback footprint into New Mexico and adding new strategic customers. The assets acquired, liabilities assumed and the results of operations of the acquired business are included in the Company’s Water Services segment. The goodwill acquired is deductible for tax purposes. The following table summarizes the consideration transferred and the estimated fair value of identified assets acquired and liabilities assumed at the date of acquisition:

​

​ | ​ | ​ | ​
Purchase price allocation |  | Amount

Divestitures

Affirm and Canadian Operations Divestitures

During the Current Period, the Company closed on four sale transactions and wound down the remaining Affirm and Canadian operations. The Company sold property and equipment with a combined net book value of $18.6 million and assigned contracts to the buyers. Additionally, two of the four transactions included the assignment of working capital. The following table summarizes sales details for each of the four transactions:

​

In connection with the Affirm crane operation divestiture in the first quarter of 2019, no gain or loss was initially recognized and goodwill was reduced by $2.6 million. Additionally, during the first quarter of 2019, the Company recorded an impairment of the remaining Affirm goodwill of $4.4 million (see Note 8).

NOTE 4—REVENUE

Effective for the year ended December 31, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), using the modified retrospective adoption method. There was no impact on the consolidated financial statements and no cumulative effect adjustment was recognized. Although most revenue recognition is governed by the new standard, the accommodations and rentals revenue continued to be guided by ASC 842 - Leases, discussed further below. The core principle of Topic 606 is that revenue is recognized when goods or services are transferred to customers in an amount that reflects consideration for which entitlement is expected in exchange for those goods or services.

ASU 2014-09 provides a five-step model for determining revenue recognition for arrangements that are within the scope of the standard: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that we will collect the consideration the Company is entitled to in exchange for the goods or services the Company transfers to the customer.

The Company elected practical expedients (i) not to access whether immaterial promised goods or services are performance obligations, (ii) not to provide disclosures on remaining performance obligations for contracts that have an original expected duration of one year or less and (iii) to exclude transaction price taxes assessed by governmental authorities as revenue.

The following factors are applicable to all three of the Company’s segments for the first six months of 2019 and 2018, respectively:

| ● | The vast majority of customer agreements are short-term, lasting less than one year

| ● | Contracts are seldom combined together as virtually all of our customer agreements constitute separate performance obligations. Each job is typically distinct, thereby not interdependent or interrelated with other customer agreements.

| ● | Most contracts allow either party to terminate at any time without substantive penalties. If the customer terminates the contract, the Company is unconditionally entitled to the payments for the products delivered to date.

| ● | Contract terminations before the end of the agreement are rare

| ● | Sales returns are rare and no sales return assets have been recognized on the balance sheet

| ● | There are no volume discounts

| ● | There are no service-type warranties

| ● | There is no long-term customer financing

In the Water Services and Water Infrastructure segments, performance obligations arise in connection with services provided to customers in accordance with contractual terms, in an amount the Company expects to collect. Services are generally sold based upon customer orders or contracts with customers that include fixed or determinable prices. Revenues are generated by services rendered and measured based on output generated, which is usually simultaneously received and consumed by customers at their job sites. As a multi-job site organization, contract terms, including pricing for the Company’s services, are negotiated on a job site level on a per-job basis. Most jobs completed in a short period of time, usually between one day and one month. Revenue is recognized as performance obligations are completed on a daily, hourly or per unit basis with unconditional rights to consideration for services rendered reflected as accounts receivable trade, net of allowance for doubtful accounts. In cases where a prepayment is received before the Company satisfies its performance obligations, a contract liability is recorded in accrued expenses and other current liabilities. Final billings generally occur once all of the proper approvals are obtained. No revenue is associated with mobilization or demobilization of personnel and equipment. Rather, mobilization and demobilization are factored into pricing for services. Billings and costs related to mobilization and demobilization is not material for customer

agreements that start in one period and end in another. As of June 30, 2019, the Company had two contracts in place lasting over a year.

In the Oilfield Chemicals segment, the typical performance obligation is to provide a specific quantity of chemicals to customers in accordance with the customer agreement in an amount the Company expects to collect. Products and services are generally sold based upon customer orders or contracts with customers that include fixed or determinable prices. Revenue is recognized as the customer takes title to chemical products in accordance with the agreement. Products may be provided to customers in packaging or delivered to the customers’ containers through a hose. In some cases, the customer takes title to the chemicals upon consumption from storage containers on their property, where the chemicals are considered inventory until customer usage. In cases where the Company delivers products and recognizes revenue before collecting payment, the Company usually has an unconditional right to payment reflected in accounts receivable trade, net of allowance for doubtful accounts. Customer returns are rare and immaterial and there were no in-process customer agreements as of June 30, 2019 lasting greater than one year.

The Company accounts for accommodations and rentals agreements as an operating lease. The Company recognizes revenue from renting equipment on a straight-line basis. Accommodations and rental contract periods are generally daily, weekly or monthly. The average lease term is less than three months and as of June 30, 2019, no rental agreements lasted more than a year.

The following table sets forth certain financial information with respect to the Company’s disaggregation of revenues by geographic location:

In the Water Services segment, the top three revenue producing regions are the Permian Basin, MidCon and Eagle Ford, which collectively comprised 74%, 73%, 74% and 70% of segment revenue for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. In the Water Infrastructure segment, the top two revenue producing regions are the Permian Basin and Bakken, which collectively comprised 81%, 82%, 82% and 83% of segment revenue for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. In the Oilfield Chemicals segment, the top two revenue producing regions are the Permian Basin and MidCon, which collectively comprised 75%, 78%, 76% and 74% of segment revenue for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

NOTE 5—LEASES

As of June 30, 2019, the Company was the lessee for approximately 580 operating leases with durations greater than a year, approximately 14 subleases, approximately 65 finance leases, and is the lessor for three owned properties. Most of the operating leases either have renewal options of between one and five years or convert to month-to-month agreements at the end of the specified lease term. In addition to normal lease activity, the four Affirm and Canadian divestitures occurring in the Current Period included the assignment of leases to the buyers. The assigned leases impacted expenses during the Current Period, but were not included in the June 30, 2019 consolidated balance sheet.

The Company’s operating leases are primarily for (i) housing personnel for operations, (ii) operational yards for storing and staging equipment, (iii) equipment used in operations, (iv) facilities used for back-office functions and (v) equipment used for back office functions. The Company has determined that it is reasonably certain to exercise future renewal options for one facility lease for the corporate office building in Gainesville, Texas. The majority of the Company’s long-term lease expenses are at fixed prices.

Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheets and the Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company has a significant number of short-term leases including month-to-month agreements that continue in perpetuity until the lessor or the Company terminates the lease agreement. Due to the volatility of the price of a barrel of oil and the short-term nature of the Company’s contracts with customers, the Company has determined that no short-term leases with indefinite renewals are reasonably certain to last more than a year into the future. When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of the Company’s leases do not provide a readily determinable implicit rate. Therefore, the Company estimates the incremental borrowing rate based on what it would pay to borrow on a collateralized basis, over a similar term based on information available at lease commencement.

The Company previously had an $18.8 million lease obligation associated with certain exit and disposal activities in connection with approximately 17 abandoned facility leases as of December 31, 2018. Upon adopting the new lease standard, the former exit-disposal cease use liability was reclassified and factored into the initial right-of-use (“ROU”) asset impairment calculation.

The financial impact of leases is listed in the tables below:

Property and Equipment Held-for-Sale and Impairments

Long-lived assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. During the first quarter of 2019, the Company made the decision to sell and wind down certain operations within its former Wellsite Services segment, including the operations of its Affirm subsidiary, its sand hauling operations and its Canadian operations. This decision led us to classify the property and equipment of these business as held-for-sale. All operations have been wound down, with $1.9 million remaining in held-for-sale as of June 30, 2019. The table below shows the property and equipment sold and divested as follows:

​

​ | ​ | ​ | ​ | ​ | ​

Total property and equipment sold and divested | ​ | ​ | ​ | $ | 22,638

​

During the Current Period, the Company recorded an impairment of $0.9 million of Canadian property and equipment to write down the carrying value based on the expected future sale proceeds. In addition, during the Current Period, the net loss on divestitures and sales of property and equipment held-for-sale was $2.8 million.

NOTE 8—GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is evaluated for impairment on at least an annual basis, or more frequently if indicators of impairment exist. The annual impairment tests are based on Level 3 inputs (see Note 12). During the first quarter of 2019, the Affirm goodwill was reduced to zero from the crane divestiture and impairment. The $4.4 million of goodwill impairment was based on the expected proceeds from selling and winding down the rest of the Affirm business. Also, in connection with the Company’s segment realignment, the Company reallocated goodwill from reporting units in the 2018 Water Solutions segment to reporting units in the 2019 Water Services and Water Infrastructure segments. The changes in the carrying amounts of goodwill by reportable segment as of June 30, 2019 and December 31, 2018 are as follows:

NOTE 9—DEBT

Credit facility and revolving line of credit

On November 1, 2017, SES Holdings and Select LLC entered into a $300.0 million senior secured revolving credit facility (the “Credit Agreement”), by and among SES Holdings, as parent, Select LLC, as borrower and certain of SES Holdings’ subsidiaries, as guarantors, each of the lenders party thereto and Wells Fargo Bank, N.A., as administrative agent, issuing lender and swingline lender (the “Administrative Agent”). The Credit Agreement also has a sublimit of $40.0 million for letters of credit and a sublimit of $30.0 million for swingline loans. Subject to obtaining commitments from existing or new lenders, the Company has the option to increase the maximum amount under the Credit Agreement by $150.0 million during the first three years following the closing. The maturity date of the Credit Agreement is the earlier of (a) November 1, 2022, and (b) the earlier termination in whole of the Commitments pursuant to Section 2.1(b) of Article VII of the Credit Agreement.

The Credit Agreement permits extensions of credit up to the lesser of $300.0 million and a borrowing base that is determined by calculating the amount equal to the sum of (i) 85% of the Eligible Billed Receivables (as defined in the Credit Agreement), plus (ii) 75% of Eligible Unbilled Receivables (as defined in the Credit Agreement), provided that this amount will not equal more than 35% of the borrowing base, plus (iii) the lesser of (A) the product of 70% multiplied by the value of Eligible Inventory (as defined in the Credit Agreement) at such time and (B) the product of 85% multiplied by the Net Recovery Percentage (as defined in the Credit Agreement) identified in the most recent Acceptable Appraisal of Inventory (as defined in the Credit Agreement), multiplied by the value of Eligible Inventory at such time, provided that this amount will not equal more than 30% of the borrowing base, minus (iv) the aggregate amount of Reserves (as defined in the Credit Agreement), if any, established by the Administrative Agent from time to time, including, if any, the amount of the Dilution Reserve (as defined in the Credit Agreement). The borrowing base is calculated on a monthly basis pursuant to a borrowing base certificate delivered by Select LLC to the Administrative Agent.

Borrowings under the Credit Agreement bear interest, at Select LLC’s election, at either the (a) one-, two-, three- or six-month LIBOR (“Eurocurrency Rate”) or (b) the greatest of (i) the federal funds rate plus 0.5%, (ii) the one-month Eurocurrency Rate plus 1% and (iii) the Administrative Agent’s prime rate (the ”Base Rate”), in each case plus an applicable margin. Interest is payable monthly in arrears. The applicable margin for Eurocurrency Rate loans ranges from 1.50% to 2.00% and the applicable margin for Base Rate loans ranges from 0.50% to 1.00%, in each case, depending on Select LLC’s average excess availability under the Credit Agreement. During the continuance of a bankruptcy event of default, automatically and during the continuance of any other default, upon the Administrative Agent’s or the required lenders’ election, all outstanding amounts under the Credit Agreement will bear interest at 2.00% plus the otherwise applicable interest rate.

The obligations under the Credit Agreement are guaranteed by SES Holdings and certain subsidiaries of SES Holdings and Select LLC and secured by a security interest in substantially all of the personal property assets of SES Holdings, Select LLC and their domestic subsidiaries.

The Credit Agreement contains certain customary representations and warranties, affirmative and negative covenants and events of default. If an event of default occurs and is continuing, the lenders may declare all amounts outstanding under the Credit Agreement to be immediately due and payable.

In addition, the Credit Agreement restricts SES Holdings’ and Select LLC’s ability to make distributions on, or redeem or repurchase, its equity interests, except for certain distributions, including distributions of cash so long as, both at the time of the distribution and after giving effect to the distribution, no default exists under the Credit Agreement and either (a) excess availability at all times during the preceding 30 consecutive days, on a pro forma basis and after giving effect to such distribution, is not less than the greater of (1) 25% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (2) $37.5 million or (b) if SES Holdings’ fixed charge coverage ratio is at least 1.0 to 1.0 on a pro forma basis, and excess availability at all times during the preceding 30 consecutive days, on a pro forma basis and after giving effect to such distribution, is not less than the greater of (1) 20% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (2) $30.0 million. Additionally, the Credit Agreement generally permits Select LLC to make distributions to allow Select Inc. to make payments required under the existing Tax Receivable Agreements. See Note 13—Related Party Transactions for further discussion of the Tax Receivable Agreements.

The Credit Agreement also requires SES Holdings to maintain a fixed charge coverage ratio of at least 1.0 to 1.0 at any time availability under the Credit Agreement is less than the greater of (i) 10% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (ii) $15.0 million and continuing through and including the first day after such time that availability under the Credit Agreement has equaled or exceeded the greater of (i) 10% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (ii) $15.0 million for 60 consecutive calendar days.

Certain lenders party to the Credit Agreement and their respective affiliates have from time to time performed, and may in the future perform, various financial advisory, commercial banking and investment banking services for the Company and its affiliates in the ordinary course of business for which they have received and would receive customary compensation. In addition, in the ordinary course of their various business activities, such parties and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investments and securities activities may involve the Company’s securities and/or instruments.

The Company had no borrowings and $45.0 million outstanding under the Credit Agreement as of June 30, 2019 and December 31, 2018, respectively. The weighted-average interest rate of outstanding borrowings under the Credit Agreement was 4.256% as of December 31, 2018. As of June 30, 2019 and December 31, 2018, the borrowing base under the Credit Agreement was $256.4 million and $270.5 million, respectively. The borrowing capacity under the Credit Agreement was reduced by outstanding letters of credit of $16.4 million and $20.8 million as of June 30, 2019 and December 31, 2018, respectively. The Company’s letters of credit have a variable interest rate between 1.50% and

Table of Contents

2.00% based on the Company’s average excess availability as outlined above. The unused portion of the available borrowings under the Credit Agreement was $240.0 million as of June 30, 2019.

Debt issuance costs are amortized to interest expense over the life of the debt to which they pertain. Total unamortized debt issuance costs as of June 30, 2019 and December 31, 2018 were $2.3 million and $2.6 million, respectively. As these debt issuance costs relate to a revolving line of credit, they are presented as a deferred charge within other assets on the consolidated balance sheets. Amortization expense related to debt issuance costs was $0.2 million, $0.2 million, $0.3 million and $0.3 million for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

The Company was in compliance with all debt covenants as of June 30, 2019.

NOTE 10—COMMITMENTS AND CONTINGENCIES

Litigation

The Company is subject to a number of lawsuits and claims arising out of the normal conduct of its business. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. Based on a consideration of all relevant facts and circumstances, including applicable insurance coverage, it is not expected that the ultimate outcome of any currently pending lawsuits or claims against the Company will have a material adverse effect on its consolidated financial position, results of operations or cash flows; however, there can be no assurance as to the ultimate outcome of these matters.

Certain subsidiaries acquired in the Rockwater Merger are under investigation by the U.S. Attorney's Office for the Middle District of Pennsylvania and the U.S. Environmental Protection Agency (the “EPA”). It is alleged that certain employees at some of the facilities altered emissions controls systems on 4% of the vehicles in the fleet in violation of the Clean Air Act. The Company is cooperating with the relevant authorities to resolve the matter. At this time no administrative, civil or criminal charges have been brought against the Company and the Company cannot estimate the possible fines and penalties that may be levied against the Company.

Self-Insured Reserves

We are self-insured up to certain retention limits with respect to workers’ compensation, general liability and vehicle liability matters. We maintain accruals for self-insurance retentions that we estimate using third-party data and claims history.

NOTE 11—EQUITY-BASED COMPENSATION

The SES Holdings 2011 Equity Incentive Plan, (“2011 Plan”) was approved by the board of managers of SES Holdings in April 2011. In conjunction with the Select 144A Offering, the Company adopted the Select Energy Services, Inc. 2016 Equity Incentive Plan (as amended, the “2016 Plan”) for employees, consultants and directors of the Company and its affiliates. Options that were outstanding under the 2011 Plan immediately prior to the Select 144A Offering were cancelled in exchange for new options granted under the 2016 Plan.

On July 18, 2017, the Select Inc. board of directors approved the First Amendment to the 2016 Plan (the “Equity Plan Amendment”), which clarifies the treatment of substitute awards under the 2016 Plan (including substitute awards that may be granted in connection with the Rockwater Merger which occurred on November 1, 2017) and allowed for the assumption by the Company of shares eligible under any pre-existing stockholder-approved plan of an entity acquired by the Company or its affiliate (including the Rockwater Energy Solutions Inc. Amended and Restated 2017 Long Term Incentive Plan (the “Rockwater Equity Plan”)), in each case subject to the listing rules of the stock exchange on which the Company’s Class A Common Stock is listed. The effectiveness of the Equity Plan Amendment was subject to approval by the Company's stockholders and the consummation of the transactions contemplated by the Merger Agreement for the Rockwater Merger. The Company’s consenting stockholders, who held a majority of the outstanding common stock of the Company, approved the Equity Plan Amendment on July 18, 2017. The Equity Plan Amendment became effective on November 1, 2017 upon the consummation of the Rockwater Merger. Currently, the maximum number of shares reserved for issuance under the 2016 Plan, taking into account the impact of the Rockwater Merger, is approximately 9.3 million shares. For all share-based compensation award types, the Company accounts for forfeitures as they occur.

Stock option awards

Stock options were granted with an exercise price equal to or greater than the fair market value of a share of Class A Common Stock as of the date of grant. Prior to the Company’s initial public offering on April 26, 2017, the Company historically valued Class A Common Stock on a quarterly basis using a market approach that includes a comparison to publicly traded peer companies using earnings multiples based on their market values and a discount for lack of marketability. This fair value measurement relied on Level 3 inputs. The estimated fair value of its stock options is expensed over their vesting period, which is generally three years from the applicable date of grant. However, certain awards granted during the years ended December 31, 2017 and 2016 in exchange for cancelled awards were immediately vested and fully exercisable on the date of grant because they were either granted in exchange for the cancellation of outstanding options granted under the 2011 Plan or the Rockwater Equity Plan, as applicable, that were fully vested and exercisable prior to such cancellation.

The Company utilized the Monte Carlo option pricing model to determine fair value of the options granted during 2018, which incorporates assumptions to value equity-based awards. The risk-free interest rate is based on the U.S. Treasury yield curve in effect for the expected term of the option at the time of grant. The expected life of the options was based on the vesting period and term of the options awarded, which is ten years.

The Company recognized $1.0 million, $1.4 million, $2.3 million and $2.7 million of compensation expense related to stock options during the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. As of June 30, 2019, there was $2.2 million of unrecognized equity-based compensation expense related to nonvested stock options. This cost is expected to be recognized over a weighted-average period of one year.

Restricted Stock Awards and Restricted Stock Units

The value of the restricted stock awards and restricted stock units issued was established by the market price of the Class A Common Stock on the date of grant and is recorded as compensation expense ratably over the vesting term, which is generally one to three years from the applicable date of grant. The Company recognized compensation expense of $2.2 million, $1.2 million, $4.0 million and $2.1 million related to the restricted stock awards and restricted stock units for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. As of June 30, 2019, there was $13.6 million of unrecognized compensation expense with a weighted-average remaining life of 1.6 years related to unvested restricted stock awards and restricted stock units.

Performance Share Units (PSUs)

During 2018 and 2019, the Company approved grants of performance share units (“PSUs”) that are subject to both performance-based and service-based vesting provisions. The number of shares of Class A Common Stock issued to a recipient upon vesting of the PSU will be calculated based on performance against certain metrics that relate to the Company’s return on asset performance over the January 1, 2018 through December 31, 2020 and January 1, 2019 through December 31, 2021 performance periods, respectively.

The target number of shares of Class A Common Stock subject to each PSU is one; however, based on the achievement of performance criteria, the number of shares of Class A Common Stock that may be received in settlement of each PSU can range from zero to 1.75 times the target number. The PSUs become earned at the end of the performance period after the attainment of the performance level has been certified by the compensation committee, which will be no later than June 30, 2021 for the 2018 PSU grants, and June 30, 2022 for the 2019 PSU grants, assuming the minimum performance metrics are achieved. The target PSUs that become earned PSUs during the performance period will be determined in accordance with the following table:

​

​ | ​ | ​
Return on Assets at Performance Period End Date | ​ | Percentage of Target PSUs Earned
Less than 9.6% | ​ | 0%
9.6% | ​ | 50%
12% | ​ | 100%
14.4% | ​ | 175%

​

The grant date fair value of PSUs granted during 2018 was $5.9 million and the grant fair value of PSUs granted during the first half of 2019 was $6.9 million. Compensation expense related to the PSUs is determined by multiplying the number of shares of Class A Common Stock underlying such awards that, based on the Company’s estimate, are probable to vest, by the measurement-date (i.e., the last day of each reporting period date) fair value and recognized using the accelerated attribution method. The Company recognized compensation expense of $0.8 million, $0.4 million, $1.7 million and $0.6 million related to the PSUs for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

As of June 30, 2019, the fair value of outstanding PSUs issued was $11.8 million. The unrecognized compensation cost related to our unvested PSUs is estimated to be $8.6 million and is expected to be recognized over a weighted-average period of 1.8 years as of June 30, 2019.

Stock-Settled Incentive Awards

Effective May 17, 2018, the Company approved grants of stock-settled incentive awards to certain key employees under the 2016 Equity Incentive Plan that are subject to both market-based and service-based vesting provisions. These awards will vest after a two-year service period and, if earned, settled in shares of Class A Common Stock. The ultimate amount earned is based on the achievement of the market metrics, which is based on the stock price of the Class A Common Stock at the vesting date, for which payout could range from 0% to 200%. Any award not earned on the vesting date is forfeited. The target amount that becomes earned during the performance period will be determined in accordance with the following table:

​

​ | ​ | ​
Stock Price at Vesting Date(1) | ​ | Percentage of Target Amount Earned
Less than $20.00 | ​ | 0%
At least $20.00, but less than $25.00 | ​ | 100%
$25.00 or greater | ​ | 200%

| (1) | The stock price at vesting date equals the greater of (i) the fair market value of a share of the Class A Common Stock on the vesting date, or (ii) the volume weighted average closing price of a share of the Class A Common Stock, as reported on the New York Stock Exchange (“NYSE”), for the 30 trading days preceding the vesting date.

The target amount of stock-settled incentive awards granted was $3.9 million. However, the ultimate settlement of the awards will be in shares of Class A Common Stock with a fair market value equal to the earned amount, which could range from 0% to 200% of the target amount depending on the stock price at vesting date.

Compensation expense associated with the stock-settled incentive awards is recognized ratably over the corresponding requisite service period. The fair value of the stock-settled incentive awards was determined using a Monte Carlo option pricing model, similar to the Black-Scholes-Merton model, and adjusted for the specific characteristics of the awards. The key assumptions in the model included price, the expected volatility of our stock, risk-free interest rate based on U.S. Treasury yield curve, cross-correlations between us and our self-determined peer companies’ asset, equity and debt-to-equity volatility.

The Company recognized stock compensation expense of $0.1 million, $0.1 million, $0.3 million and $0.1 million related to the stock-settled incentive awards for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. The unrecognized compensation cost related to our unvested stock-settled incentive awards is estimated to be $0.5 million and is expected to be recognized over approximately 11 months as of June 30, 2019.

Employee Stock Purchase Plan (ESPP)

We have an Employee Stock Purchase Plan (“ESPP”) under which employees that have been continuously employed for at least one year may purchase shares of Class A Common Stock at a discount. The plan provides for four offering periods for purchases: December 1 through February 28, March 1 through May 31, June 1 through August 31 and September 1 through November 30. At the end of each offering period, enrolled employees purchase shares of Class A Common Stock at a price equal to 95% of the market value of the stock on the last day of such offering period. The purchases are made at the end of an offering period with funds accumulated through payroll deductions over the course of the offering period. Subject to limitations set forth in the plan and under IRS regulations, eligible employees may elect to contribute a maximum of $15,000 to the plan in a single calendar year. The plan is deemed to be noncompensatory.

The following table summarizes ESPP activity (in thousands, except shares):

Share-repurchases

During the Current Quarter and Current Period, the Company repurchased 0 and 82,092 shares, respectively, of Class A Common Stock in the open market and repurchased 26,716 and 70,410 shares, respectively, of Class A Common Stock in connection with employee minimum tax withholding requirements for units vested under the 2016 Plan. All repurchased shares were retired. This was accounted for as a decrease to paid-in-capital of $1.5 million and a decrease to Class A Common Stock of approximately $1,500.

NOTE 12—FAIR VALUE MEASUREMENT

The Company utilizes fair value measurements to measure assets and liabilities in a business combination or assess impairment of property and equipment, intangible assets and goodwill. Fair value is defined as the amount at which an asset (or liability) could be bought (or incurred) or sold (or settled) in an orderly transaction between market participants at the measurement date. Further, ASC 820, Fair Value Measurements, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value, and includes certain disclosure requirements. Fair value estimates are based on either (i) actual market data or (ii) assumptions that other market participants would use in pricing an asset or liability, including estimates of risk.

ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:

Level 1—Unadjusted quoted prices for identical assets or liabilities in active markets.

Level 2—Quoted prices for similar assets or liabilities in non-active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3—Inputs that are unobservable and significant to the fair value measurement (including the Company’s own assumptions in determining fair value).

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. There were no transfers into, or out of, the three levels of the fair value hierarchy for the six months ended June 30, 2019 or the year ended December 31, 2018. The following table presents information about the Company’s assets measured at fair value on a non-recurring basis as of June 30, 2019.

| (1) | Amount represents carrying value at the date of assessment.

Other fair value considerations

The carrying values of the Company’s current financial instruments, which include cash and cash equivalents, accounts receivable trade and accounts payable, approximate their fair value as of June 30, 2019 and December 31, 2018, due to the short-term maturity of these instruments. The carrying value of bank debt as of December 31, 2018 approximated fair value due to variable market rates of interest. The fair value of bank debt as of December 31, 2018, which is a Level 3 measurement, was estimated based on the Company’s incremental borrowing rates for similar types of borrowing arrangements, when quoted market prices are not available. The Company did not have any bank debt as of June 30, 2019. The estimated fair values of the Company’s financial instruments are not necessarily indicative of the amounts that would be realized in a current market exchange. The Affirm goodwill impairment was based on the Company’s estimate as of March 31, 2019 of fair value based on the expected proceeds to sell the remaining property and equipment utilizing Level 3 inputs. The property and equipment impairment during the Current Period was based on the expected proceeds from selling a portion of the remaining Canadian property and equipment utilizing Level 3 inputs.

The first of the Tax Receivable Agreements, which the Company entered into with Legacy Owner Holdco and Crestview Partners II GP, L.P. (“Crestview GP”), generally provides for the payment by the Company to such TRA Holders of 85% of the net cash savings, if any, in U.S. federal, state and local income and franchise tax that the Company actually realizes (computed using simplifying assumptions to address the impact of state and local taxes) or is deemed to realize in certain circumstances in periods after the Select 144A Offering as a result of, as applicable to each such TRA Holder, (i) certain increases in tax basis that occur as a result of the Company’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of all or a portion of such TRA Holder’s SES Holdings LLC Units in connection with the Select 144A Offering or pursuant to the exercise of the Exchange Right or the Company’s Call Right and (ii) imputed interest deemed to be paid by the Company as a result of, and additional tax basis arising from, any payments the Company makes under such Tax Receivable Agreement.

NOTE 17—SEGMENT INFORMATION

Select Inc. is an oilfield services company that provides solutions to the onshore oil and natural gas industry in the United States. The Company’s services are offered through three operating segments. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the CODM in deciding how to allocate resources and assess performance. The Company’s CODM assesses performance and allocates resources on the basis of the three reportable segments. Corporate and other expenses that do not individually meet the criteria for segment reporting are reported separately as Corporate or Other. Each operating segment reflects a reportable segment led by separate managers that report directly to the Company’s CODM.

During the first quarter of 2019, the Company made the decision to sell and wind down certain operations within its former Wellsite Services segment, including the operations of its Affirm subsidiary, its sand hauling operations and its Canadian operations. As a result, the Company reevaluated its segment structure and changed its reportable segments to Water Services, Water Infrastructure, and Oilfield Chemicals.

The Company’s CODM assesses performance and allocates resources on the basis of the following three reportable segments:

Water Services — The Water Services segment consists of the Company’s services businesses including water transfer, flowback and well testing, fluids hauling, containment, and water treatment and water network automation. Additionally, this segment includes the operations of our accommodations and rentals business, which were previously a part of the former Wellsite Services segment.

Water Infrastructure — The Water Infrastructure segment consists of the Company’s strategic infrastructure assets and ongoing infrastructure development projects, including operations associated with our water sourcing and pipelines, produced water gathering systems and salt water disposal wells.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes included elsewhere in this report, as well as the historical consolidated financial statements and notes thereto included in our 2018 Form 10-K. This discussion and analysis contains forward-looking statements based upon our current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors as described under “Cautionary Note Regarding Forward-Looking Statements.”

This discussion relates to the three and six months ended June 30, 2019 (the “Current Quarter” and the “Current Period”, respectively) and the three and six months ended June 30, 2018 (the “Prior Quarter” and the “Prior Period”, respectively).

Overview

We are a leading provider of water-management solutions to the oil and gas industry in the United States (“U.S.”). We also develop, manufacture and deliver chemical solutions for use in oil and gas well completions and production operations. Within the major shale plays in the U.S., we believe we are a market leader in water sourcing, water transfer (both by permanent pipeline and temporary hose) and temporary water containment prior to its use in drilling and completion activities associated with hydraulic fracture stimulation or “fracking,” which we refer to collectively as “pre-frac water services”. In addition, we provide testing and flowback services immediately following the well completion. In most of our areas of operations, we also provide additional complementary water-related services that support oil and gas well completion and production activities, including water network automation, treatment, hauling, water recycling and disposal. We also manufacture a full suite of specialty chemicals used in the fracturing process, and we provide chemicals needed by our customers to increase oil and gas production and lower production costs over the life of a well. We believe we are the only company in the oilfield services industry that combines full life cycle water-management services with the ability to develop and provide related chemical products.

Our operations have benefited from the investments and acquisitions we have made, and we continue to invest both in our existing business and in new infrastructure and technology. When evaluating new investment decisions, we prioritize high returns on long-lived assets where applicable. One way we do this is through margin-enhancing capital expenditures, which often comprises upgrading or automating equipment in order to increase margin realization from those assets. One example of this type of investment is replacing conventional water transfer pumps with automated pumps, which lowers labor costs, increases reliability and improves environmental safeguards for our customers. Another area of focus is longer-lived infrastructure assets in areas we believe will experience consistently high levels of completion activity. We have successfully executed these types of investments both in the Bakken, through our fixed infrastructure investments there, through our GRR Acquisition in the northern Delaware Basin and with our recently announced northern Delaware Basin pipeline project. Additionally, as market opportunities continue to grow for treating and re-using produced water for new well completions, we are also focused on developing and expanding our production-related services including our existing produced water gathering infrastructure to help manage growing produced water volumes. The quality of water used for a well completion directly impacts the completion chemicals that are used in the frac fluid system. Our knowledge and expertise related to treatment, recycling and frac fluid chemistry allows us to provide our customers with sustainable solutions across a range of various water attributes.

For our Oilfield Chemicals segment, the opening of our Midland Friction Reducer production line has saved us freight and logistics cost relative to shipping this high-volume product out of our Tyler, Texas production facility. We continue to make investments in driving operational efficiencies with our in-basin manufacturing that will continue to reduce unnecessary logistics and freight cost, making us more competitive and more nimble to our customers. The trend of increased use of produced water may require additional chemical treatment solutions, which we are well positioned to provide given our water treatment capabilities.

We have executed these acquisitions and investments within the context of a steadily improving balance sheet. As of June 30, 2019, we have no outstanding bank debt and a net cash position. We prioritize sustained positive free

cash flow and a strong balance sheet, and evaluate potential acquisitions and investments in the context of those priorities, in addition to the economics of the opportunity. We believe this approach provides the Company with additional flexibility to evaluate larger investments as well as improved resilience in a sustained downturn versus many of our peers.

Going forward, we may pursue selected acquisitions of complementary assets, businesses and technologies, and believe we are well positioned to capture attractive opportunities due to our market position, customer and landowner relationships and industry experience and expertise.

Our Segments

Our services are offered through three operating segments: (i) Water Services; (ii) Water Infrastructure; and (iii) Oilfield Chemicals.

| ● | Water Services. The Water Services segment consists of the Company’s services businesses including water transfer, flowback and well testing, fluids hauling, containment, and water treatment and water network automation, primarily serving E&P companies. Additionally, this segment includes the operations of our accommodations and rentals business, which were previously a part of our former Wellsite Services segment.

| ● | Water Infrastructure. The Water Infrastructure segment consists of the Company’s strategic infrastructure assets and ongoing infrastructure development projects, including operations associated with our water sourcing and pipelines, produced water gathering systems and salt water disposal wells, primarily serving E&P companies.

| ● | Oilfield Chemicals. The Oilfield Chemicals segment develops, manufactures and provides a full suite of chemicals used in hydraulic fracturing, stimulation, cementing and well completions, including polymer slurries, crosslinkers, friction reducers, buffers breakers and other chemical technologies, to leading pressure pumping service companies in the United States. This segment also provides chemicals needed by our customers to increase oil and gas production and lower production costs over the life of a well.

The results of our remaining service lines that were previously a part of our former Wellsite Services segment including the operations of our Affirm subsidiary, our sand hauling operations and our Canadian operations are combined in the “Other” category. As of June 30, 2019, these operations have ceased, and we do not expect regular recurring revenue going forward from this segment.

How We Generate Revenue

We currently generate most of our revenue through our water-management services associated with hydraulic fracturing, provided through our Water Services and Water Infrastructure segments. We generate the majority of our revenue through customer agreements with fixed pricing terms and earn revenue when delivery of services is provided, generally at our customers’ sites. While we have some long-term pricing arrangements, particularly in our Water Infrastructure segment, most of our water and water-related services are priced based on prevailing market conditions, giving due consideration to the specific requirements of the customer.

We also generate revenue by providing completion, specialty chemicals and production chemicals through our Oilfield Chemicals segment. We invoice the majority of our Oilfield Chemicals customers for services provided based on the quantity of chemicals used or pursuant to short-term contracts as the customer’s needs arise.

Costs of Conducting Our Business

The principal expenses involved in conducting our business are labor costs, equipment costs (including depreciation, repair, rental and maintenance and leasing costs), raw materials and water sourcing costs and fuel costs. Our fixed costs are relatively low. Most of the costs of serving our customers are variable, i.e., they are only incurred when we provide water and water-related services, or chemicals and chemical-related services to our customers.

Labor costs associated with our employees and contract labor represent the most significant costs of our business. We incurred labor and labor-related costs of $122.6 million, $140.0 million, $264.7 million and $278.9 million for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. The majority of our recurring labor costs are variable and are incurred only while we are providing our operational services. We also incur costs to employ personnel to sell and supervise our services and perform maintenance on our assets, which is not directly tied to our level of business activity. Additionally, we incur selling, general and administrative costs for compensation of our administrative personnel at our field sites and in our operational and corporate headquarters. In light of the challenging activity and pricing trends, management has taken direct action during the Current Quarter to reduce operating and equipment costs, as well as selling, general and administrative costs, in order to proactively manage these expenses as a percentage of revenue.

We incur significant equipment costs in connection with the operation of our business, including depreciation, repair and maintenance, rental and leasing costs. We incurred equipment costs of $61.6 million, $71.1 million, $127.6 million and $139.8 million for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

We incur significant transportation costs associated with our service lines, including fuel and freight. We incurred fuel and freight costs of $20.2 million, $24.5 million, $42.5 million and $47.3 million for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. Fuel prices impact our transportation costs, which affect the pricing and demand for our services and have an impact on our results of operations.

We incur raw material costs in manufacturing our chemical products, as well as for water that we source for our customers. We incurred raw material costs of $66.0 million, $69.3 million, $136.3 million and $137.8 million for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

Industry Overview

During the Current Quarter, the average spot price of West Texas Intermediate (“WTI”) (Cushing) crude oil was $59.88 versus an average price of $68.07 for the Prior Quarter. The average Henry Hub natural gas spot price during the Current Quarter was $2.56 versus an average of $2.86 for the Prior Quarter. The decline in oil and gas prices in the Current Quarter relative to the Prior Quarter has negatively impacted the pace of completions activity in 2019, relative to the Prior Period. Though oil prices have modestly recovered in recent months, many operators prepared and announced their capital budgets during a period of lower prices. With most operators appearing to prioritize free cash flow over production growth at this time, we do not see much potential upside in activity from Current Quarter levels for the second half of 2019. Additionally, capital markets, especially the IPO market, do not appear favorably disposed towards the Oil & Gas industry at this time. While we believe that the current oil prices and production profiles could lead to increased operator cash flow and additional activity in the future, current indications lead us not to anticipate large incremental sums of capital potentially entering the market to create higher demand for our services over the course of 2019.

While we cannot predict the future direction of oil or natural gas prices, our discussions with customers and the improving financial metrics of many U.S. onshore-focused operators lead us to believe that current price levels support significant capital investment by our customers over the longer term to maintain and grow oil and gas production from U.S. onshore resources. Additionally, the high rate of decline of U.S. onshore unconventional resources requires significant ongoing investment just to maintain production levels.

Trends beyond oil and natural gas prices present both support and challenges. While we believe leading-edge lateral lengths and proppant use are plateauing, the average operator continues to catch up to this leading edge. The continued trend towards multi-well pad development, executed within a limited time frame, has increased the overall complexity of well completions, while increasing frac efficiency and the use of lower cost in-basin sand have decreased total costs for our customers. This multi-well pad development, combined with recent upstream acreage consolidation and the emerging trends around the reuse applications of produced water, particularly in the Permian, provides significant opportunity for companies like us that can deliver increasingly complex solutions for our E&P customers across the full completion and production lifecycle of wells. We note the continued efficiency gains in the well completions process can limit the days we spend on the wellsite and therefore negatively impact the total revenue opportunity.

The trend of increased use of produced water may require additional chemical treatment solutions, which we are well positioned to provide given our water treatment capabilities and our knowledge base within our Oilfield Chemicals segment. Additionally, this trend supports more complex “on the fly” solutions that treat, proportion, and blend various streams of water and chemicals at the wellsite. This complexity favors service companies able to provide advanced technology solutions.

How We Evaluate Our Operations

We use a variety of operational and financial metrics to assess our performance. Among other measures, management considers each of the following:

| ● | Revenue;

| ● | Gross Profit;

| ● | Gross Margins;

| ● | EBITDA; and

| ● | Adjusted EBITDA.

Revenue

We analyze our revenue and assess our performance by comparing actual monthly revenue to our internal projections and across periods. We also assess incremental changes in revenue compared to incremental changes in direct operating costs, and selling, general and administrative expenses across our operating segments to identify potential areas for improvement, as well as to determine whether segments are meeting management’s expectations.

Gross Profit

To measure our financial performance, we analyze our gross profit, which we define as revenues less direct operating expenses (including depreciation and amortization expenses). We believe gross profit provides insight into profitability and true operating performance of our assets. We also compare gross profit to prior periods and across segments to identify trends as well as underperforming segments.

Gross Margins

Gross margins provide an important gauge of how effective we are at converting revenue into profits. This metric works in tandem with gross profit to ensure that we do not increase gross profit at the expense of lower margins, thus decreasing our return on capital employed, nor pursue higher gross margins exclusively at the expense of declining gross profits. We track gross margins by segment and service line and compare them across prior periods and across segments and service lines to identify trends as well as underperforming segments.

42

Table of Contents

EBITDA and Adjusted EBITDA

We view EBITDA and Adjusted EBITDA as important indicators of performance. We define EBITDA as net income/(loss), plus interest expense, income taxes, and depreciation and amortization. We define Adjusted EBITDA as EBITDA plus/(minus) loss/(income) from discontinued operations, plus any impairment charges or asset write-offs pursuant to GAAP, plus/(minus) non-cash losses/(gains) on the sale of assets or subsidiaries, non-recurring compensation expense, non-cash compensation expense, and non-recurring or unusual expenses or charges, including severance expenses, transaction costs, or facilities-related exit and disposal-related expenditures, plus/(minus) foreign currency losses/(gains) and plus any inventory write-downs. See “—Note Regarding Non-GAAP Financial Measures—EBITDA and Adjusted EBITDA” for more information and a reconciliation of EBITDA and Adjusted EBITDA to net income (loss), the most directly comparable financial measure calculated and presented in accordance with GAAP.

Factors Affecting the Comparability of Our Results of Operations to Our Historical Results of Operations

Our future results of operations may not be comparable to our historical results of operations for the periods presented, primarily for the reasons described below.

Acquisition and Divestiture Activity

As described above, we are continuously evaluating potential investments, particularly in water infrastructure and other water-related services and technology. To the extent we consummate acquisitions, any incremental revenues or expenses from such transactions are not included in our historical results of operations.

Pro Well Acquisition

On November 20, 2018, we completed our acquisition of the assets of Pro Well Testing and Wireline, Inc. (“Pro Well”). Our historical financial statements for periods prior to November 20, 2018 do not include the results of operations of Pro Well.

Affirm Divestitures

We sold the Affirm crane and field services businesses on February 26, 2019 and June 28, 2019, respectively. We wound down the rest of Affirm during the Current Quarter. Affirm accounted for $58.9 million of revenue during 2018. Following the two divestitures, the divested operations were not included in the consolidated results of operations.

Canadian Operations Divestitures

On March 19, 2019, we sold over half of our Canadian operations which accounted for approximately $40.0 million of annual revenue during 2018. On April 1, 2019, we sold and wound down the rest of the Canadian operations which accounted for approximately $8.6 million of annual revenue during 2018. Following the divestitures, the divested Canadian operations were not included in the consolidated results of operations.

Sand Hauling Wind Down

During the Current Period, we wound down our sand hauling operations and sold certain of our sand hauling property and equipment. Sand hauling accounted for $37.0 million of annual revenue during 2018.

Proceeds received from Divestitures and Wind Down

During the Current Period, we received $30.1 million from divestitures and fixed asset sale activity in connection with the sale and wind down of our Affirm subsidiary and the sand hauling and Canadian operations.

Impact of Industry Conditions on Our Operating Results

Demand for oilfield services depends substantially on drilling, completion and production activity by E&P companies, which, in turn, depends largely upon the current and anticipated profitability of developing oil and natural gas reserves. Our business is directly affected by our customers’ capital spending to develop and produce oil and gas in the United States. The significant decline in oil and gas prices that began in the fourth quarter of 2014 caused a reduction in the development activities of most of our customers and their spending on our services in 2015 and 2016, which led to a reduction in the rates we were able to charge and the utilization of our assets. In 2017 and through the third quarter of 2018, our clients steadily increased their spending as compared to 2016 levels as oil prices generally recovered; however, in the fourth quarter of 2018, we experienced a pullback in spending by our customers, driven by a decline in oil prices and seasonal factors. While oil prices have since improved, customers have prioritized spending within their cash flows and capital budgets, and additional volatility or declines could result in our customers cancelling or curtailing their spending on our services. In the discussion of our operating results below, we reference the fluctuations in industry conditions in connection with certain changes in our results of operations.

Revenue

Our revenue decreased $69.4 million, or 17.6%, to $323.9 million for the Current Quarter compared to $393.2 million for the Prior Quarter. The decrease was driven by $31.6 million lower revenue from the combination of our Affirm subsidiary, sand hauling operations and Canadian operations, all of which were fully divested and wound down during the Current Period. Also impacting the decrease was $31.9 million of lower Water Services revenue, $4.0 million of lower Water Infrastructure revenue and $1.8 million of lower Oilfield Chemicals revenue discussed below. For the Current Quarter, our Water Services, Water Infrastructure, Oilfield Chemicals and Other segments constituted 62.4%, 16.0%, 19.4% and 2.2% of our total revenue, respectively, compared to 59.5%, 14.2%, 16.5%, and 9.8%, respectively, for the Prior Quarter. The 2018 adoption of Accounting Standards Update 2014-09, Revenue from Contracts with Customers, did not have a material impact on revenue recognition. The revenue decrease by operating segment were as follows:

Table of Contents

Water Services. Revenue decreased $31.9 million, or 13.7%, to $202.0 million for the Current Quarter compared to $234.0 million for the Prior Quarter. The decrease was primarily attributable to reduced activity and pricing pressures in our water transfer business.

Water Infrastructure. Revenue decreased by $4.0 million, or 7.2%, to $51.7 million for the Current Quarter compared to $55.7 million for the Prior Quarter, primarily due to reduced activity on our Bakken pipeline system, partially offset by increased revenues in the Permian.

Oilfield Chemicals. Revenue decreased $1.8 million, or 2.8%, to $63.0 million for the Current Quarter compared to $64.8 million for the Prior Quarter, primarily due to reduced demand for guar-based frac fluid systems, partially offset by increased friction reducer sales.

Other. Other revenue decreased $31.6 million, or 81.5%, to $7.2 million for the Current Quarter compared to $38.8 million in the Prior Quarter as our Affirm subsidiary, sand hauling operations and Canadian operations were divested and wound down as of June 30, 2019.

Costs of Revenue

Costs of revenue decreased $52.6 million, or 15.6%, to $283.9 million for the Current Quarter compared to $336.5 million for the Prior Quarter. The decrease was primarily due to $25.7 million lower combined costs from our Affirm subsidiary, sand hauling operations and Canadian operations, all of which were divested and wound down during the Current Period. Also impacting the decrease were $21.4 million lower Water Services costs, $4.4 million lower Oilfield Chemicals costs and $1.6 million lower depreciation costs further discussed below.

Water Services. Cost of revenue decreased $21.4 million, or 12.1%, to $155.2 million for the Current Quarter compared to $176.6 million for the Prior Quarter. Cost of revenue as a percent of revenue increased from 75.5% to 76.8% due to pricing pressures we could not fully offset with cost reductions.

Water Infrastructure. Cost of revenue increased $0.6 million, or 1.5%, to $38.5 million for the Current Quarter compared to $37.9 million for the Prior Quarter. Cost of revenue as a percent of revenue increased from 68.0% to 74.4% primarily due to a decline in contribution from our high-margin Bakken pipeline system.

Oilfield Chemicals. Costs of revenue decreased $4.4 million, or 7.6%, to $54.1 million for the Current Quarter compared to $58.5 million for the Prior Quarter. Cost of revenue as a percent of revenue decreased from 90.3% to 85.8% due primarily to freight cost savings from our Midland, Texas plant.

Other. Other costs decreased $25.7 million, or 77.5%, to $7.4 million for the Current Quarter compared to $33.1 million in the Prior Quarter primarily due to the divestitures discussed above.

Depreciation and Amortization. Depreciation and amortization expense decreased $1.6 million, or 5.3%, to $28.8 million for the Current Quarter compared to $30.4 million for the Prior Quarter, primarily due to the divestitures discussed above.

Gross Profit

Gross profit decreased by $16.8 million, or 29.6%, to a gross profit of $39.9 million for the Current Quarter compared to a gross profit of $56.7 million for the Prior Quarter primarily due to a $10.5 million decrease in Water Services gross profit stemming from lower revenue, $5.9 million lower gross profit from the combination of our Affirm subsidiary, sand hauling operations and Canadian operations, all of which were divested and wound down during the Current Period, and a $4.6 million decrease to Water Infrastructure gross profit due to lower revenue and slightly higher costs. This was partially offset by $2.6 million higher Oilfield Chemicals gross profit and $1.6 million lower depreciation expense. Gross margin as a percent of revenue was 12.3% and 14.4% in the Current Quarter and Prior Quarter, respectively.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $0.4 million, or 1.6%, to $27.3 million for the Current Quarter compared to $26.9 million for the Prior Quarter.

Lease Abandonment Costs

Lease abandonment costs were $0.2 million and $2.0 million in the Current Quarter and Prior Quarter, respectively. During the Current Quarter, lease abandonment costs primarily related to the wind-down of impaired right-of-use assets from previously abandoned properties, partially offset by sublease income. The Prior Quarter costs were primarily due to excess facility capacity stemming from the Rockwater Merger.

Net Interest Expense

Net interest expense decreased by $0.5 million, or 37.5%, to $0.8 million during the Current Quarter compared to $1.3 million in the Prior Quarter primarily due to lower average borrowings due to paying down our debt.

Net Income

Net income decreased by $17.0 million, or 67.8%, to net income of $8.1 million for the Current Quarter compared to net income of $25.0 million for the Prior Quarter primarily due to lower Water Services and Water Infrastructure revenue, higher relative Water Infrastructure costs, and lower gross profit from the combination of our Affirm subsidiary, sand hauling operations and Canadian operations, as discussed above. This was partially offset by lower lease abandonment costs, lower interest expense and lower impairment expense.

Revenue

Our revenue decreased $83.1 million, or 10.8%, to $686.5 million for the Current Period compared to $769.6 million for the Prior Period. The decrease was primarily due to $50.5 million lower revenue from the combination of our Affirm subsidiary, sand hauling operations and Canadian operations, all of which were fully divested and wound down during the Current Period. Also impacting the change was $29.6 million lower Water Services revenue and $4.5 million lower Water Infrastructure revenue, partially offset by slightly higher Oilfield Chemicals revenue discussed below. For the Current Period, our Water Services, Water Infrastructure, Oilfield Chemicals and Other segments constituted 61.6%, 15.3%, 18.9% and 4.2% of our total revenue, respectively, compared to 58.7%, 14.3%, 16.7%, and 10.3%, respectively, for the Prior Period. The 2018 adoption of Accounting Standards Update 2014-09, Revenue from Contracts with Customers, did not have a material impact on revenue recognition. The revenue variances by operating segment were as follows:

​

Table of Contents

Water Services. Revenue decreased $29.6 million, or 6.5%, to $422.6 million for the Current Period compared to $452.2 million for the Prior Period. The decrease was primarily due to lower water transfer and fluids hauling revenue primarily attributable to reduced activity and pricing pressure, partially offset by increases in revenues from flowback and well testing, rentals and containment.

Water Infrastructure. Revenue decreased by $4.5 million, or 4.1%, to $105.3 million for the Current Period compared to $109.8 million for the Prior Period, primarily due to reduced activity on our Bakken pipeline system.

Oilfield Chemicals. Revenue increased $1.4 million, or 1.1%, to $129.8 million for the Current Period compared to $128.4 million for the Prior Period, primarily due to higher friction reducer sales stemming from larger manufacturing capacity from our Midland, Texas plant, which more than offset the declining sale of guar related products.

Other. Other revenue decreased $50.5 million, or 63.7%, to $28.8 million for the Current Period compared to $79.2 million in the Prior Period as our Affirm subsidiary, sand hauling operations and Canadian operations were divested and wound down.

Costs of Revenue

Costs of revenue decreased $64.4 million, or 9.7%, to $600.6 million for the Current Period compared to $665.0 million for the Prior Period. The decrease was primarily due to $40.4 million lower costs from the combination of our Affirm subsidiary, sand hauling operations and Canadian operations, all of which were divested and wound down during the Current Period. Also impacting the decrease was $22.9 million lower Water Services costs, primarily due to aligning our cost structure to lower revenue, further discussed below.

Water Services. Cost of revenue decreased $22.9 million, or 6.7%, to $318.3 million for the Current Period compared to $341.2 million for the Prior Period. Cost of revenue as a percent of revenue was relatively flat, moving from 75.5% to 75.3%.

Water Infrastructure. Cost of revenue increased $1.9 million, or 2.4%, to $79.9 million for the Current Period compared to $78.0 million for the Prior Period. Cost of revenue as a percent of revenue increased from 71.0% to 75.8% primarily due to a decline in contribution from our high-margin Bakken pipeline system.

Oilfield Chemicals. Costs of revenue decreased $2.0 million, or 1.7%, to $113.6 million for the Current Period compared to $115.6 million for the Prior Period. Cost of revenue as a percent of revenue decreased from 90.0% to 87.5% due primarily to freight cost-savings from our Midland, Texas plant.

Other. Other costs decreased $40.4 million, or 58.6%, to $28.5 million for the Current Period compared to $68.9 million in the Prior Period, primarily due to the divestitures discussed above.

Depreciation and Amortization. Depreciation and amortization expense decreased $1.0 million, or 1.6%, to $60.4 million for the Current Period compared to $61.3 million for the Prior Period.

Gross Profit

Gross profit decreased by $18.7 million, or 17.9%, to a gross profit of $85.9 million for the Current Period compared to a gross profit of $104.7 million for the Prior Period, primarily due to $10.1 million lower gross profit from the combination of our Affirm subsidiary, sand hauling operations and Canadian operations, all of which were divested and wound down during the Current Period. Also impacting the decrease was $6.6 million lower gross profit from Water Services and $6.4 million lower gross profit from Water Infrastructure discussed above. These were partially offset by $3.4 million higher gross profit from Oilfield Chemicals and $1.0 million lower depreciation costs discussed above. Gross margin as a percent of revenue was 12.5% and 13.6% in the Current Period and Prior Period, respectively.

Table of Contents

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $7.1 million, or 13.6%, to $59.7 million for the Current Period compared to $52.6 million for the Prior Period. The increase was primarily driven by increased equity incentive plan costs and severance expense in connection with the divestitures.

Lease Abandonment Costs

Lease abandonment costs were $1.3 million and $3.1 million in the Current Period and Prior Period, respectively. The Current Period costs were primarily due to Canadian lease terminations in connection with divesting and winding down the Canadian business. The Prior Period costs were primarily due to excess facility capacity stemming from the Rockwater Merger.

Net Interest Expense

Net interest expense decreased by $0.6 million, or 22.5%, to $1.9 million during the Current Period compared to $2.5 million in the Prior Period, primarily due to lower average borrowings.

Net Income

Net income decreased by $31.7 million, or 77.0%, to net income of $9.5 million for the Current Period compared to net income of $41.2 million for the Prior Period, primarily due to $18.7 million lower gross profit stemming from divestitures and lower revenue discussed above, $7.7 million higher losses on sales of property and equipment, net and $7.1 million higher selling, general and administrative costs discussed above, partially offset by $1.8 million lower lease abandonment costs discussed above.

Comparison of Non-GAAP Financial Measures

We view EBITDA and Adjusted EBITDA as important indicators of performance. We define EBITDA as net income (loss), plus interest expense, income taxes, and depreciation and amortization. We define Adjusted EBITDA as EBITDA plus/(minus) loss/(income) from discontinued operations, plus any impairment charges or asset write-offs pursuant to GAAP, plus/(minus) non-cash losses/(gains) on the sale of assets or subsidiaries, non-recurring compensation expense, non-cash compensation expense, and non-recurring or unusual expenses or charges, including severance expenses, transaction costs, or facilities-related exit and disposal-related expenditures, plus/(minus) foreign currency losses/(gains) and plus any inventory write-downs.

Our board of directors, management and investors use EBITDA and Adjusted EBITDA to assess our financial performance because it allows them to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure (such as varying levels of interest expense), asset base (such as depreciation and amortization) and items outside the control of our management team. We present EBITDA and Adjusted EBITDA because we believe they provide useful information regarding the factors and trends affecting our business in addition to measures calculated under GAAP.

Note Regarding Non-GAAP Financial Measures

EBITDA and Adjusted EBITDA

EBITDA and Adjusted EBITDA are not financial measures presented in accordance with GAAP. We believe that the presentation of these non-GAAP financial measures will provide useful information to investors in assessing our financial performance and results of operations. Net income is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. Our non-GAAP financial measures should not be considered as alternatives to the most directly comparable GAAP financial measure. Each of these non-GAAP financial measures has important limitations as an analytical tool due to exclusion of some but not all items that affect the most directly comparable GAAP financial measures. One should not consider EBITDA or Adjusted EBITDA in isolation or as substitutes for an analysis of our results as reported under GAAP. Because EBITDA and Adjusted EBITDA may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. For further discussion, please see “Item 6. Selected Financial Data” in our 2018 Form 10-K.

The following table presents a reconciliation of EBITDA and Adjusted EBITDA to our net income, which is the most directly comparable GAAP measure for the periods presented:

EBITDA was $39.2 million for the Current Quarter compared to $57.8 million for the Prior Quarter. The $18.6 million decrease in EBITDA was primarily driven by a decrease of $10.5 million in Water Services gross profit, a decrease of $4.6 million in Water Infrastructure gross profit and a decrease of $5.9 million in gross profit from the operations being divested and wound down, partially offset by an increase of $2.6 million in Oilfield Chemicals gross profit. Adjusted EBITDA was $51.6 million for the Current Quarter compared to $68.2 million for the Prior Quarter. The $16.6 million decrease is primarily attributable to the items discussed above.

EBITDA was $74.4 million for the Current Period compared to $106.9 million for the Prior Period. The $32.5 million decrease in EBITDA was primarily driven by a decrease of $6.6 million in Water Services gross profit, a decrease of $6.4 million in Water Infrastructure gross profit, a decrease of $10.1 million in gross profit from the

operations being divested and wound down and an increase in selling, general and administrative costs of $7.1 million, partially offset by an increase of $3.4 million in Oilfield Chemicals gross profit. Adjusted EBITDA was $105.0 million for the Current Period compared to $127.9 million for the Prior Period. The $22.9 million decrease in Adjusted EBITDA was primarily due to the $32.5 million decrease in EBITDA discussed above partially offset by an $11.5 million increase in non-cash losses on sales of assets or subsidiaries.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity to date have been capital contributions from our members, the net proceeds from the Select 144A Offering, the net proceeds from the IPO, borrowing capacity under our current Credit Agreement and our prior credit facility and cash flows from operations. Our primary uses of capital have been to maintain our asset base, implement technological advancements, make capital expenditures to support organic growth and to fund acquisitions. Depending on market conditions and other factors, we may also issue debt and equity securities if needed.

We intend to finance most of our capital expenditures, contractual obligations and working capital needs with cash generated from operations and borrowings under our Credit Agreement. For a discussion of the Credit Agreement, see “—Credit Agreement” below. Although we cannot provide any assurance, we believe that our operating cash flow and available borrowings under our Credit Agreement will be sufficient to fund our operations for at least the next twelve months.

As of June 30, 2019, cash and cash equivalents totaled $23.8 million and we had approximately $240.0 million of available borrowing capacity under our Credit Agreement. As of June 30, 2019, the borrowing base under the Credit Agreement was $256.4 million, we had no outstanding borrowings and the outstanding letters of credit totaled $16.4 million. As of August 2, 2019, we had no outstanding borrowings, the borrowing base under the Credit Agreement was $256.3 million, the outstanding letters of credit totaled $19.9 million, and the available borrowing capacity under the Credit Agreement was $236.4 million.

On November 1, 2017, in connection with the closing of the Rockwater Merger (the “Closing”), SES Holdings and Select LLC entered into a $300.0 million senior secured revolving credit facility (the “Credit Agreement”), by and among SES Holdings, as parent, Select LLC, as borrower, certain of SES Holdings’ subsidiaries, as guarantors, each of the lenders party thereto and Wells Fargo Bank, N.A., as administrative agent, issuing lender and swingline lender (the “Administrative Agent”). The Credit Agreement has a sublimit of $40.0 million for letters of credit and a sublimit of $30.0 million for swingline loans. Subject to obtaining commitments from existing or new lenders, we have the option to increase the maximum amount under the Credit Agreement by $150.0 million during the first three years following the Closing.

The maturity date of the Credit Agreement is the earlier of (a) November 1, 2022, and (b) the termination in whole of the Commitments pursuant to Section 2.1(b) of Article VII of the Credit Agreement.

The Credit Agreement permits extensions of credit up to the lesser of $300.0 million and a borrowing base that is determined by calculating the amount equal to the sum of (i) 85.0% of the Eligible Billed Receivables (as defined in the Credit Agreement), plus (ii) 75.0% of Eligible Unbilled Receivables (as defined in the Credit Agreement), provided that this amount will not equal more than 35.0% of the borrowing base, plus (iii) the lesser of (A) the product of 70.0% multiplied by the value of Eligible Inventory (as defined in the Credit Agreement) at such time and (B) the product of 85.0% multiplied by the Net Recovery Percentage (as defined in the Credit Agreement) identified in the most recent Acceptable Appraisal of Inventory (as defined in the Credit Agreement), multiplied by the value of Eligible Inventory at such time, provided that this amount will not equal more than 30.0% of the borrowing base, minus (iv) the aggregate amount of Reserves (as defined in the Credit Agreement), if any, established by the Administrative Agent from time to time, including, if any, the amount of the Dilution Reserve (as defined in the Credit Agreement). The borrowing base is calculated on a monthly basis pursuant to a borrowing base certificate delivered by Select LLC to the Administrative Agent.

Borrowings under the Credit Agreement bear interest, at Select LLC’s election, at either the (a) one-, two-, three- or six-month LIBOR (“Eurocurrency Rate”) or (b) the greatest of (i) the federal funds rate plus 0.5%, (ii) the one-month Eurocurrency Rate plus 1.0% and (iii) the Administrative Agent’s prime rate (the “Base Rate”), in each case plus an applicable margin, and interest shall be payable monthly in arrears. The applicable margin for Eurocurrency Rate loans ranges from 1.50% to 2.00% and the applicable margin for Base Rate loans ranges from 0.50% to 1.00%, in each case, depending on Select LLC’s average excess availability under the Credit Agreement. During the continuance of a bankruptcy event of default, automatically and during the continuance of any other default, upon the Administrative Agent’s or the required lenders’ election, all outstanding amounts under the Credit Agreement will bear interest at 2.00% plus the otherwise applicable interest rate.

The obligations under the Credit Agreement are guaranteed by SES Holdings and certain subsidiaries of SES Holdings and Select LLC and secured by a security interest in substantially all of the personal property assets of SES Holdings, Select LLC and their domestic subsidiaries.

The Credit Agreement contains certain customary representations and warranties, affirmative and negative covenants and events of default. If an event of default occurs and is continuing, the lenders may declare all amounts outstanding under the Credit Agreement to be immediately due and payable.

In addition, the Credit Agreement restricts SES Holdings’ and Select LLC’s ability to make distributions on, or redeem or repurchase, its equity interests, except for certain distributions, including distributions of cash so long as, both at the time of the distribution and after giving effect to the distribution, no default exists under the Credit Agreement and either (a) excess availability at all times during the preceding 30 consecutive days, on a pro forma basis and after giving effect to such distribution, is not less than the greater of (1) 25.0% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (2) $37.5 million or (b) if SES Holdings’ fixed charge coverage ratio is at least 1.0 to 1.0 on a pro forma basis, and excess availability at all times during the preceding 30 consecutive days, on a pro forma basis and after giving effect to such distribution, is not less than the greater of (1) 20.0% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (2) $30.0 million. Additionally, the Credit Agreement generally permits Select LLC to make distributions to allow Select Inc. to make payments required under the existing Tax Receivable Agreements.

The Credit Agreement also requires SES Holdings to maintain a fixed charge coverage ratio of at least 1.0 to 1.0 at any time availability under the Credit Agreement is less than the greater of (i) 10.0% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (ii) $15.0 million and continuing through and including the first day after such time that availability under the Credit Agreement has equaled or exceeded the greater of (i) 10.0% of the lesser of (A) the maximum revolver amount and (B) the then-effective borrowing base and (ii) $15.0 million for 60 consecutive calendar days.

We were in compliance with all debt covenants as of June 30, 2019.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The demand, pricing and terms for oilfield services provided by us are largely dependent upon the level of activity for the U.S. oil and gas industry. Industry conditions are influenced by numerous factors over which we have no control, including, but not limited to: the supply of and demand for oil and gas; current prices as well as expectations about future prices of oil and gas; the cost of exploring for, developing, producing and delivering oil and gas; the expected decline in rates of current production; the discovery rates of new oil and gas reserves; available pipeline and other transportation capacity; weather conditions; domestic and worldwide economic conditions; political instability in oil-producing countries; environmental regulations; technical advances affecting energy consumption; the price and availability of alternative fuels; the ability of oil and gas producers to raise equity capital and debt financing; and merger and divestiture activity among oil and gas producers.

The level of activity in the U.S. oil and gas industry is volatile. Expected trends in oil and gas production activities may not continue and demand for our services may not reflect the level of activity in the industry. Any prolonged substantial reduction in oil and gas prices would likely affect oil and gas drilling and completion activity and therefore affect demand for our services. A material decline in oil and gas prices or U.S. activity levels could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Interest Rate Risk

As of June 30, 2019, we had no outstanding borrowings under our Credit Agreement. As of August 2, 2019, we had no outstanding borrowings and approximately $236.4 million of available borrowing capacity under our Credit Agreement. Interest is calculated under the terms of our Credit Agreement based on our selection, from time to time, of one of the index rates available to us plus an applicable margin that varies based on certain factors. We do not currently have or intend to enter into any derivative arrangements to protect against fluctuations in interest rates applicable to our outstanding indebtedness.

Foreign Currency Exchange Risk

We are exposed to fluctuations between the U.S. dollar and the Canadian dollar with regard to the activities of our former Canadian subsidiary, acquired in the Rockwater Merger, which designated the Canadian dollar as its functional currency. With the recent divestitures of our Canadian operations, we anticipate minimal future exposure to foreign currency exchange risk.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that the information required to be disclosed by us in our reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

As required by Rule 13a-15(b) under the Exchange Act, we have evaluated, under the supervision and with the participation of management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2019.

Status of Previously Identified Material Weaknesses

Our management concluded that our internal control over financial reporting and our disclosure controls and procedures were ineffective as of December 31, 2018 as a result of control deficiencies related to the purchase price accounting related to the Rockwater Merger and the reconciliation of fixed assets physical counts with the general ledger that constituted material weaknesses. Specifically, the Company did not design and maintain effective controls with respect to the identification and substantiation of fixed assets purchased in the Rockwater Merger and to the reconciliation of our fixed assets physical counts with the general ledger.

In response to the material weaknesses described above, during the quarter ended March 31, 2019, we implemented new internal controls which we believe will remediate the previously identified material weaknesses. We are currently testing the operating effectiveness of these new internal controls.

Changes in Internal Control over Financial Reporting

Other than noted above, there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2019 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently a party to any legal proceedings that, if determined adversely against us, individually or in the aggregate, would have a material adverse effect on our financial position, results of operations or cash flows. We are, however, named defendants in certain lawsuits, investigations and claims arising in the ordinary course of conducting our business, including certain environmental claims and employee-related matters, and we expect that we will be named defendants in similar lawsuits, investigations and claims in the future. While the outcome of these lawsuits, investigations and claims cannot be predicted with certainty, we do not expect these matters to have a material adverse impact on our business, results of operations, cash flows or financial condition. We have not assumed any liabilities arising out of these existing lawsuits, investigations and claims.

In December 2016, Rockwater was notified by the U.S. Attorney’s Office for the Middle District of Pennsylvania that it is being investigated for altering emissions control systems on several of its vehicles. We are cooperating with the investigation and have determined that mechanics servicing our vehicle fleet may have installed software on certain vehicles and modified a few other vehicles to deactivate or bypass the factory-installed emissions control systems. At present, it appears that 31 vehicles in Pennsylvania were modified in this manner, apparently to improve vehicle performance and reliability. As a result of a company-wide investigation undertaken voluntarily and in cooperation with the U.S. Department of Justice, we have determined that approximately 30 additional company vehicles outside of Pennsylvania may have been altered. As of the date of the initiation of the investigation, we operated approximately 1,400 vehicles in the U.S., and the modified vehicles constituted less than 5% of our fleet at such time. We are unable to predict at this time whether any administrative, civil or criminal charges will be brought against us, although we have learned that we may be the target of a criminal investigation, and it is possible that other individuals or we could become targets. We are cooperating with the U.S. Department of Justice in all aspects of the investigation and have instituted procedures to ensure that our mechanics do not tamper with or bypass any emissions control systems when they are performing vehicle maintenance, and we have also reached an agreement with the U.S. Department of Justice providing for either the restoration or removal from service of those vehicles that were modified. In December 2018, we met with the U.S. Attorney’s Office for the Middle District of Pennsylvania to begin discussions regarding a resolution of this matter. Although we are unable to predict the timing or outcome of this investigation, we note that in similar circumstances, the EPA has imposed fines of up to $7,200 per altered vehicle and has also required the responsible party to disgorge any financial benefit that it may have derived.

Item 1A. Risk Factors

There have been no material changes to the Risk Factors disclosed in the 2018 Form 10-K.
