BUSINESS AND BASIS OF PRESENTATION
BUSINESS AND BASIS OF PRESENTATION	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. 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.
