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”). We are a leading provider of comprehensive water-management and chemical solutions to the oil and gas industry in the U.S. As a leader in the water solutions industry, we place the utmost importance on safe, environmentally responsible management of oilfield water throughout the lifecycle of a well. Additionally, we believe that responsibly managing water resources through our operations to help conserve and protect the environment in the communities in which we operate is paramount to our continued success. Class A and Class B Common Stock: Exchange rights: 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 U.S. (“GAAP”) and pursuant to the rules and regulations of 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 Quarterly Report relates to the three and nine months ended September 30, 2022 (the “Current Quarter” and the “Current Period”, respectively) and the three and nine months ended September 30, 2021 (the “Prior Quarter” and the “Prior Period”, respectively). The Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”), filed with the SEC on February 23, 2022, includes certain definitions and a summary of significant accounting policies and should be read in conjunction with this Quarterly Report. 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 may not be indicative of the results to be expected for the full year, in part due to the war between Russia and Ukraine, the continuing effects of the COVID-19 pandemic and large variations in oil and natural gas prices during the Current Quarter and Current Period. 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 in which the Company exercises significant influence over operating and financial policies are accounted for using the equity-method, and investments in entities for which the Company does not have significant control or influence are accounted for using the cost method or other appropriate basis as applicable. As of September 30, 2022, the Company had three equity-method investments and one cost-method investment. 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. Our investments in unconsolidated entities are summarized below and are included in the assets of our Water Services segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year ​ ​ ​ ​ As of September 30, ​ As of December 31, Type of Investment attained Accounting method Balance Sheet Location ​ 2022 2021 ​ ​ ​ ​ ​ (in thousands) 20% minority interest 2011 Cost-method Other long-term assets, net ​ $ 60 ​ $ 120 Notes receivable (1) 2020 Amortized cost basis Other long-term assets, net ​ ​ — ​ ​ 4,446 21% minority interest (1) 2021 Equity-method Other long-term assets, net ​ ​ 4,608 ​ ​ — 40% minority interest (2) 2021 Equity-method Other long-term assets, net ​ ​ 5,313 ​ ​ 1,779 49% minority interest (3) 2021 Equity-method Other long-term assets, net ​ ​ 2,633 ​ ​ 142 (1) Investment in notes receivable converted to equity-method investment during the Current Period.

SIGNIFICANT ACCOUNTING POLICIES
SIGNIFICANT ACCOUNTING POLICIES	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, 2021, included in the 2021 Form 10-K. 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 reserve, income taxes, self-insurance liabilities, share-based compensation, contingent liabilities, lease-related reasonably certain option exercise assessments, 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. Allowance for credit losses: The change in the allowance for credit losses is as follows: ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2022 ​ ​ (in thousands) Balance as of December 31, 2021 ​ $ 4,401 Increase to allowance based on a percentage of revenue ​ 2,016 Charge-offs ​ ​ (1,555) Recoveries ​ ​ 29 Balance as of September 30, 2022 ​ $ 4,891 ​ ​ Asset retirement obligations: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine months ended September 30, 2022 ​ (in thousands) Balance as of December 31, 2021 $ 29,551 Accretion expense, included in depreciation and amortization expense ​ 855 Acquired AROs ​ 13,029 Divested ​ ​ (1,490) Payments ​ ​ (779) Balance as of September 30, 2022 $ 41,166 ​ ​ ​ ​ Short-term ARO liability ​ ​ 4,490 Long-term ARO liability ​ ​ 36,676 Balance as of September 30, 2022 ​ $ 41,166 ​ We review the adequacy of our ARO liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed.

(“Nuverra”) for total consideration of $35.9 million based on the closing price of the Company’s shares of Class A Common Stock on February 23, 2022 (the “Nuverra Acquisition”). Consideration transferred consisted of 4,203,323 shares of Class A Common Stock. The acquisition strengthened Select’s geographic footprint with a unique set of water logistics and infrastructure assets, particularly in the Bakken, Haynesville and Northeast, while continuing to expand Select’s production-related revenues. Select also acquired a 60-mile underground twin pipeline network in the Haynesville Shale in Texas and Louisiana. This pipeline network is used for the collection of produced water for transport to interconnected disposal wells and the delivery or re-delivery of water from water sources to operator locations for use in well completion activities. Additionally, Nuverra operates a landfill facility in North Dakota located on a 50-acre site. The facility provides a unique opportunity for Select to expand its logistics capabilities into a new service offering. The acquisition is expected to result in a bargain purchase gain based on our preliminary evaluation, as Nuverra was experiencing financial distress and actively evaluating strategic alternatives leading up to the transaction. ​ The Nuverra 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 estimates, judgments and assumptions. The Company has engaged third-party valuation experts to assist in the purchase price allocation. These estimates, judgments and assumptions and valuation of the property and equipment acquired, current assets, current liabilities and long-term liabilities have not been finalized as of September 30, 2022. The Nuverra debt, including accrued interest, totaled $18.8 million, and was repaid during the Current Period after the acquisition was completed. The assets acquired and liabilities assumed are included in the Company’s Water Services and Water Infrastructure segments. The Company incurred $0.5 million and $3.6 million of transaction-related costs related to this acquisition in the Current Quarter and Current Period, respectively, and such costs are included in selling, general and administrative within the consolidated statements of operations. ​ The Company assumed $1.6 million of severance liabilities in connection with the Nuverra acquisition and $0.1 million is included in accrued salaries and benefits as of September 30, 2022. ​ ​ The following table summarizes the consideration transferred and the estimated fair value of identified assets acquired and liabilities assumed at the date of acquisition: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Preliminary purchase price allocation ​ As Reported as of June 30, 2022 ​ Current Quarter Adjustment ​ Amount Consideration transferred ​ (in thousands) Class A Common Stock (4,203,323 shares) ​ $ 35,854 ​ $ — ​ $ 35,854 Total consideration transferred ​ 35,854 ​ ​ — ​ ​ 35,854 Less: identifiable assets acquired and liabilities assumed ​ ​ ​ ​ ​ ​ ​ ​ Working capital ​ 7,818 ​ ​ (117) ​ ​ 7,701 Property and equipment ​ 65,138 ​ ​ — ​ ​ 65,138 Right-of-use assets ​ 2,931 ​ ​ — ​ ​ 2,931 Other long-term assets ​ ​ 100 ​ ​ — ​ ​ 100 Long-term debt ​ ​ (18,780) ​ ​ — ​ ​ (18,780) Long-term ARO ​ ​ (12,980) ​ ​ — ​ ​ (12,980) Long-term lease liabilities ​ ​ (1,189) ​ ​ — ​ ​ (1,189) Total identifiable net assets acquired ​ ​ 43,038 ​ ​ (117) ​ ​ 42,921 Bargain Purchase Gain ​ (7,184) ​ ​ 117 ​ ​ (7,067) Fair value allocated to net assets acquired, net of bargain purchase gain $ 35,854 ​ $ — ​ $ 35,854 ​ HB Rentals Acquisition On December 3, 2021, the Company, through its subsidiary Peak Oilfield Services, LLC, completed the acquisition of certain assets of H.B. Rentals, L.C. (“HB Rentals”), an operating subsidiary of Superior Energy Services, Inc. (“Superior”), for total initial consideration of $8.7 million based on the closing price of the Company’s shares of Class A Common Stock on December 2, 2021 (the “HB Rentals Acquisition”). Consideration transferred consisted of 1,211,375 shares of Class A Common Stock and $1.5 million in cash. The Company paid $1.1 million on April 1, 2022, representing the final working capital settlement. The Company acquired the U.S. onshore assets of HB Rentals, including working capital. This acquisition strengthened the Company’s accommodations and rentals footprint in the Permian, Haynesville, MidCon, Northeast and Rockies regions and added revenue-producing fixed assets including a significant number of skid houses and trailer houses. The acquisition resulted in a bargain purchase gain in part due to the seller recently emerging from bankruptcy and deciding to divest domestic assets and operations and focus on international operations. The HB Rentals 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 estimates, judgments and assumptions. These estimates, judgments and assumptions and valuation of the property and equipment acquired, current assets, current liabilities and long-term liabilities were finalized as of June 30, 2022. The assets acquired and liabilities assumed are included in the Company’s Water Services segment. The Company incurred $0.1 million of transaction-related costs related to this acquisition in the Current Period, and such costs are included in selling, general and administrative within the consolidated statements of operations. ​ ​ 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 ​ As Reported as of December 31, 2021 ​ Current Period Adjustment ​ Amount Consideration transferred ​ (in thousands) Class A Common Stock (1,211,375 shares) ​ $ 7,135 ​ $ — ​ $ 7,135 Cash paid ​ ​ 1,526 ​ ​ — ​ 1,526 Final working capital settlement ​ ​ — ​ ​ 1,084 ​ ​ 1,084 Total consideration transferred ​ ​ 8,661 ​ ​ 1,084 ​ 9,745 Less: identifiable assets acquired and liabilities assumed ​ ​ ​ ​ ​ Working capital ​ ​ 29 ​ ​ 880 ​ 909 Property and equipment ​ ​ 14,091 ​ ​ 929 ​ 15,020 Right-of-use assets ​ ​ 1,316 ​ ​ — ​ 1,316 Long-term lease liabilities ​ ​ (835) ​ ​ — ​ ​ (835) Total identifiable net assets acquired ​ ​ 14,601 ​ ​ 1,809 ​ 16,410 Bargain Purchase Gain ​ ​ (5,940) ​ ​ (725) ​ (6,665) Fair value allocated to net assets acquired, net of bargain purchase gain ​ $ 8,661 ​ $ 1,084 $ 9,745 ​ Agua Libre Midstream and water-related assets from Basic Energy Services Acquisition On October 1, 2021, the Company completed the acquisition of certain assets of Agua Libre Midstream, LLC (“Agua Libre”) and other water-related assets, operations and assumed liabilities from Basic Energy Services, Inc. (“Basic”) for total initial consideration of $21.1 million based on the closing price of the Company’s shares of Class A Common Stock on September 30, 2021 (the “Agua Libre and Basic Acquisition”). Consideration transferred consisted of 902,593 shares of Class A Common Stock and $16.4 million in cash. The Company acquired substantially all of the water-related assets and ongoing operations of Agua Libre and Basic, including working capital. With this acquisition, the Company acquired a solid production services footprint in Texas, New Mexico, Oklahoma and North Dakota, as well as more than 550,000 barrels per day of permitted disposal capacity. The acquisition resulted in a bargain purchase gain as the seller was distressed and decided to divest its assets and operations to multiple buyers as operations were wound down and the business was shuttered. The Agua Libre and Basic 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 estimates, judgments and assumptions. The Company also engaged third-party valuation experts to assist in the purchase price allocation. These estimates, judgments and assumptions and valuation of the property and equipment acquired, current assets, current liabilities and long-term liabilities have been finalized as of September 30, 2022. The assets acquired and liabilities assumed are included in the Company’s Water Services and Water Infrastructure segments. The Company incurred $1.4 million, $0.6 million and $1.4 million of transaction-related costs related to this acquisition in the Prior Quarter, Current Period and Prior Period, respectively, and such costs are included in selling, general and administrative within the consolidated statements of operations. ​ ​ 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 ​ As Reported as of December 31, 2021 ​ Current Period Adjustment ​ Amount Consideration transferred ​ (in thousands) Class A Common Stock (902,593 shares) ​ $ 4,684 ​ $ — ​ $ 4,684 Cash paid ​ ​ 16,394 ​ ​ — ​ ​ 16,394 Total consideration transferred ​ ​ 21,078 ​ ​ — ​ 21,078 Less: identifiable assets acquired and liabilities assumed ​ ​ ​ ​ ​ ​ ​ ​ Working capital ​ ​ (506) ​ ​ 37 ​ (469) Property and equipment ​ ​ 41,000 ​ ​ 6,330 ​ 47,330 Right-of-use assets ​ ​ 309 ​ ​ — ​ 309 Long-term ARO ​ ​ (15,810) ​ ​ — ​ ​ (15,810) Long-term lease liabilities ​ ​ (281) ​ ​ 10 ​ ​ (271) Total identifiable net assets acquired ​ ​ 24,712 ​ ​ 6,377 ​ ​ 31,089 Bargain Purchase Gain ​ ​ (3,634) ​ ​ (6,377) ​ (10,011) Fair value allocated to net assets acquired, net of bargain purchase gain ​ $ 21,078 ​ $ — $ 21,078 ​ Complete Energy Services Acquisition ​ On July 9, 2021, the Company completed the acquisition (the “Complete Acquisition”) of Complete Energy Services, Inc. (“Complete”), an operating subsidiary of Superior Energy Services, Inc. (“Superior”) for initial consideration of $34.5 million based on the closing price of the Company’s shares of Class A Common Stock on July 9, 2021. Consideration transferred consisted of 3.6 million shares of Class A Common Stock and $14.2 million in cash. In October 2021, the Company paid $0.2 million related to the settlement of the working capital which resulted in a final purchase price of $34.7 million. The Company acquired substantially all of the water-related assets, liabilities and ongoing operations of Complete as well as Superior’s well testing operations, including working capital. Superior retained certain non-core and non-water-related assets that were part of Complete as part of the transaction. This acquisition expanded the Company’s water-related services and infrastructure footprint and strengthened the geographic footprint, particularly in the Mid-Continent, Permian and Rockies. The acquisition resulted in a bargain purchase gain in part due to the seller recently emerging from bankruptcy and deciding to divest domestic assets and operations and focus on international operations. ​ The Complete 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 estimates, judgments and assumptions. The Company also engaged third-party valuation experts to assist in the purchase price allocation. These estimates, judgments and assumptions and valuation of the property and equipment acquired, current assets, current liabilities and long-term liabilities were finalized as of June 30, 2022. The assets acquired and liabilities assumed are included in the Company’s Water Services and Water Infrastructure segments.

REVENUE
REVENUE	NOTE 4—REVENUE ​ The Company follows ASU 2014-09, Revenue from Contracts with Customers (Topic 606) Leases, The following factors are applicable to all three of the Company’s segments for the Current Quarter, Prior Quarter, Current Period and Prior Period, 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 services rendered and 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 minimal 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 are 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 credit losses. 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. Mobilization and demobilization are factored into the pricing for services. Billings and costs related to mobilization and demobilization are not material for customer agreements that start in one period and end in another. As of September 30, 2022, the Company had nine contracts in place for these segments lasting over one year. The Company has recorded a $2.6 million contract liability associated with one of the nine long-term contracts as of September 30, 2022, of which $1.2 million is recognized in accrued expenses and other current liabilities and $1.4 million is recognized in other long-term liabilities in the accompanying consolidated balance sheets. This liability was $8.2 million as of December 31, 2021 and the Company has recognized $5.6 million in revenue during the Current Period. The Company expects this contract liability to be converted to revenue under the terms of the contract as it is earned. Accommodations and rentals revenue is included in the Water Services segment and 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 September 30, 2022, there were no material rental agreements in effect lasting more than one year. During the Current Quarter, Prior Quarter, Current Period and Prior Period, approximately $21.1 million, $8.1 million, $54.3 million and $21.0 million of accommodations and rentals revenue was accounted for under ASC 842 lease guidance, with the remainder accounted for under ASC 606 revenue guidance. 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 credit losses. Customer returns are rare and immaterial and there were no material in-process customer agreements for this segment as of September 30, 2022, lasting greater than one year. The following table sets forth certain financial information with respect to the Company’s disaggregation of revenues by geographic location: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended September 30, ​ Nine months ended September 30, ​ ​ 2022 2021 ​ 2022 2021 ​ ​ (in thousands) ​ Geographic Region ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Permian Basin ​ $ 176,357 ​ $ 93,976 ​ $ 462,481 ​ $ 248,535 ​ Rockies ​ ​ 42,139 ​ ​ 25,412 ​ ​ 113,756 ​ ​ 44,630 ​ Marcellus/Utica ​ ​ 41,160 ​ ​ 17,956 ​ ​ 98,913 ​ ​ 42,874 ​ Eagle Ford ​ ​ 40,213 ​ ​ 27,827 ​ ​ 113,505 ​ ​ 73,181 ​ Mid-Continent ​ ​ 30,758 ​ ​ 18,925 ​ ​ 91,548 ​ ​ 36,928 ​ Haynesville/E.

Refer to “Note 10—Debt” in the Company’s Annual Report on Form 10-K for a discussion of the Prior Credit Agreement. The Sustainability-Linked Credit Facility also has a sublimit of $40.0 million for letters of credit and $27.0 million for swingline loans, respectively. Subject to obtaining commitments from existing or new lenders, Select LLC has the option to increase the maximum amount under the senior secured credit facility by $135.0 million during the first three years following the Restatement Date. The Sustainability-Linked Credit Facility permits extensions of credit up to the lesser of $270.0 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 Sustainability-Linked Credit Facility), plus (ii) 75% of Eligible Unbilled Receivables (as defined in the Sustainability-Linked Credit Facility), 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 Sustainability-Linked Credit Facility) at such time and (B) the product of 85% multiplied by the Net Recovery Percentage (as defined in the Sustainability-Linked Credit Facility) identified in the most recent Acceptable Appraisal of Inventory (as defined in the Sustainability-Linked Credit Facility), 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 Sustainability-Linked Credit Facility), if any, established by the Administrative Agent from time to time, including, if any, the amount of the Dilution Reserve (as defined in the Sustainability-Linked Credit Facility). 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 Sustainability-Linked Credit Facility bear interest, at Select LLC’s election, at either the (a) one- or three-month Term SOFR (as defined in the Sustainability-Linked Credit Facility) or (b) the greatest of (i) the federal funds rate plus 0.5%, (ii) one-month Term SOFR plus 1% 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 Term SOFR loans ranges from 1.75% to 2.25% and the applicable margin for Base Rate loans ranges from 0.75% to 1.25%, in each case, depending on Select LLC’s average excess availability under the Sustainability-Linked Credit Facility, as set forth in the table below. 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 Sustainability-Linked Credit Facility will bear interest at 2.00% plus the otherwise applicable interest rate. The Sustainability-Linked Credit Facility is scheduled to mature on the fifth anniversary of the Restatement Date. ​ ​ ​ ​ ​ ​ ​ ​ Level ​ Average Excess Availability ​ Base Rate Margin ​ SOFR Margin ​ ​ ​ ​ ​ ​ ​ I ​ < 33.33% of the commitments ​ 1.25% ​ 2.25% II ​ < 66.67% of the commitments and ≥ 33.33% of the commitments ​ 1.00% ​ 2.00% III ​ ≥ 66.67% of the commitments ​ 0.75% ​ 1.75% ​ ​ ​ ​ ​ ​ Level ​ Average Revolver Usage ​ Unused Line Fee Percentage ​ ​ ​ ​ ​ I ​ ≥ 50% of the commitments ​ 0.250% II ​ < 50% of the commitments ​ 0.375% ​ Under the Sustainability-Linked Credit Facility, the interest rate margin and the facility fee rates are also subject to adjustments based on Select LLC’s performance of specified sustainability target thresholds with respect to (i) total recordable incident rate, as the Employee Health and Safety Metric and (ii) barrels of produced water recycled at permanent or semi-permanent water treatment and recycling facilities owned or operated, as the Water Stewardship Metric, in each case, subject to limited assurance verification by a qualified independent external reviewer. The adjustment for the interest rate margin is a range of plus and minus 5.0 basis points and the adjustment for the fee margin is a range of plus and minus 1.0 basis point, subject to the mechanics under the Sustainability-Linked Credit Facility. The obligations under the Sustainability-Linked Credit Facility 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 Sustainability-Linked Credit Facility 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 Sustainability-Linked Credit Facility to be immediately due and payable. In addition, the Sustainability-Linked Credit Facility 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 Sustainability-Linked Credit Facility 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) $33.75 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) $27.0 million. Additionally, the Sustainability-Linked Credit Facility generally permits Select LLC to make distributions required under its existing Tax Receivable Agreements. See “Note 12—Related Party Transactions—Tax Receivable Agreements” for further discussion of the Tax Receivable Agreements. The Sustainability-Linked Credit Facility 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 Sustainability-Linked Credit Facility 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 Sustainability-Linked Credit Facility 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 Sustainability-Linked Credit Facility 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.

EQUITY-BASED COMPENSATION
EQUITY-BASED COMPENSATION	NOTE 10—EQUITY-BASED COMPENSATION The SES Holdings 2011 Equity Incentive Plan (the “2011 Plan”) was approved by the board of managers of SES Holdings in April 2011. In conjunction with the private placement of 16,100,000 shares of the Company’s Class A Common Stock on December 20, 2016 (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 May 8, 2020, the Company’s stockholders approved an amendment to the 2016 Plan to increase the number of shares of the Company’s Class A Common Stock that may be issued under the 2016 Plan by 4,000,000 shares and to make certain other administrative changes. The 2016 Plan includes share recycling provisions that allow shares subject to an award that are withheld or surrendered to the Company in payment of any exercise price or taxes or an award that expires or is cancelled, forfeited or otherwise terminated without actual delivery of the underlying shares of Class A Common Stock to be considered not delivered and thus available to be granted as new awards under the 2016 Plan. Currently, the maximum number of shares reserved for issuance under the 2016 Plan is approximately 13.3 million shares, with approximately 2.9 million shares available to be issued as of September 30, 2022. For all share-based compensation award types, the Company accounts for forfeitures as they occur. Stock Option Awards The Company has outstanding stock option awards as of September 30, 2022 but there have been no option grants since 2018. The 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. The expected life of the options at the time of the grant was based on the vesting period and term of the options awarded, which was ten years. A summary of the Company’s stock option activity and related information as of and for the Current Period is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the nine months ended September 30, 2022 ​ ​ ​ ​ ​ ​ ​ Weighted-average ​ ​ ​ ​ ​ ​ ​ Weighted-average ​ Grant Date Value ​ Aggregate Intrinsic ​ Stock Options Exercise Price Term (Years) Value (in thousands) (a) Beginning balance, outstanding 2,074,216 ​ $ 16.89 ​ 4.4 ​ $ — Exercised ​ (70,000) ​ ​ 8.70 ​ ​ ​ ​ ​ Forfeited (9,411) ​ ​ 20.00 ​ ​ ​ ​ ​ Expired ​ (316,878) ​ ​ 17.41 ​ ​ ​ ​ ​ Ending balance, outstanding 1,677,927 ​ $ 17.12 ​ 4.4 ​ $ — Ending balance, exercisable ​ 1,677,927 ​ $ 17.12 ​ 4.4 ​ $ — Nonvested as of September 30, 2022 ​ — ​ $ — ​ ​ ​ ​ ​ ​ (a) The Company recognized no compensation expense related to stock options during the Current Quarter, Prior Quarter or Current Period and a nominal amount of compensation expense during the Prior Period. As of September 30, 2022, all equity-based compensation expense related to stock options had been recognized. Restricted Stock Awards The value of the restricted stock awards granted 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 $3.7 million, $2.4 million, $10.3 million and $5.4 million related to the restricted stock awards for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. As of September 30, 2022, there was $20.4 million of unrecognized compensation expense with a weighted-average remaining life of 1.7 years related to unvested restricted stock awards. A summary of the Company’s restricted stock awards activity and related information for the Current Period is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ For the nine months ended September 30, 2022 ​ ​ ​ ​ Weighted-average ​ Restricted Stock Awards Grant Date Fair Value Nonvested as of December 31, 2021 ​ 3,144,513 ​ $ 6.35 Granted ​ 2,529,231 ​ ​ 8.14 Vested ​ (1,534,748) ​ ​ 6.91 Forfeited ​ (87,242) ​ ​ 7.26 Nonvested as of September 30, 2022 ​ 4,051,754 ​ $ 7.24 ​ Performance Share Units (PSUs) During 2020, 2021 and 2022, the Company approved grants of PSUs that are subject to both performance-based and service-based vesting provisions related to (i) return on asset performance (“ROA”) in comparison to thirteen peer companies and (ii) Adjusted Free Cash Flow (“FCF”) performance percentage. The number of shares of Class A Common Stock issued to a recipient upon vesting of the PSUs will be calculated based on ROA and FCF performance over the applicable period from either January 1, 2020 through December 31, 2022, January 1, 2021 through December 31, 2023 or January 1, 2022 through December 31, 2024. During 2021, the Company also approved grants of PSUs subject to both performance-based and service-based vesting conditions based on adjusted earnings before taxes and depreciation (“Adjusted EBITDA”) as defined in the agreement. The target PSUs granted in 2021 connected with Adjusted EBITDA would vest at 100% only if the minimum Adjusted EBITDA threshold was met. All Adjusted EBITDA-linked PSUs granted in 2021 did not achieve the performance-based vesting conditions and were forfeited. The target number of shares of Class A Common Stock subject to each remaining PSU granted in 2020, 2021 and 2022 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, 2023 for the 2020 PSU grants, June 30, 2024 for the 2021 PSU grants, and June 30, 2025, for the 2022 PSU grants, assuming the applicable minimum performance metrics are achieved. The target PSUs granted in 2020 that become earned connected with the ROA in comparison to other companies will be determined based on the Company’s Average Return on Assets (as defined in the applicable PSU agreement) relative to the Average Return on Assets of the peer companies (as defined in the applicable PSU agreement) in accordance with the following table, but only if the Company’s Average Return on Assets is equal to or greater than 5% during the performance period. The target PSUs granted in 2021 and 2022 removed the 5% minimum ROA for the Company and added that the Company must have a positive Total Shareholder Return (as defined in the applicable PSU agreement) over the performance period. As a result of this market condition being added, the 2021 and 2022 PSUs will be valued each reporting period utilizing a Black-Scholes model. ​ ​ ​ ​ Ranking Among Peer Group ​ Percentage of Target Amount Earned Outside of Top 10 ​ 0% Top 10 ​ 50% Top 7 ​ 100% Top 3 ​ 175% ​ The target PSUs that become earned in connection with the adjusted FCF performance percentage will be determined (as defined in the applicable PSU agreement) in accordance with the following table: ​ ​ ​ ​ Adjusted FCF Performance Percentage ​ Percentage of Target Amount Earned Less than 70% ​ 0% 70% ​ 50% 100% ​ 100% 130% ​ 175% ​ The fair value on the date the PSUs were granted during 2022, 2021 and 2020 was $5.0 million, $4.4 million and $4.4 million, respectively. 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 $0.1 million, a credit to compensation expense of $0.1 million and compensation expense of $0.7 million and $0.8 million related to the PSUs for the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. As of September 30, 2022, the unrecognized compensation cost related to our unvested PSUs is estimated to be $4.5 million and is expected to be recognized over a weighted-average period of 1.9 years. However, this compensation cost will be adjusted as appropriate throughout the applicable performance periods. The following table summarizes the information about the PSUs outstanding as of September 30, 2022: ​ ​ ​ ​ ​ PSUs Nonvested as of December 31, 2021 ​ 2,205,604 Target shares granted ​ 665,992 Target shares forfeited (1) ​ (872,956) Target shares outstanding as of September 30, 2022 ​ 1,998,640 (1) All PSUs granted in 2019 and all PSUs granted in 2021 tied to Adjusted EBITDA did not achieve the respective performance targets and were forfeited. Employee Stock Purchase Plan (ESPP) The Company has 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 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): ​ ​ ​ ​ ​ ​ For the nine months ended ​ September 30, 2022 Cash received for shares issued ​ $ 35 Shares issued ​ ​ 4,681 ​ Share Repurchases During the Current Quarter, the Company repurchased 40,060 shares of Class A Common Stock in connection with employee minimum tax withholding requirements for shares vested under the 2016 Plan. All repurchased shares were retired. During the Current Quarter, the repurchases were accounted for as a decrease to paid-in-capital of $0.3 million and a decrease to Class A Common Stock of less than $1,000. During the Current Period, the Company repurchased 2,297,985 shares of Class A Common Stock in the open market and repurchased 496,998 shares of Class A Common Stock in connection with employee minimum tax withholding requirements for shares vested under the 2016 Plan and the cashless exercise of stock options. All repurchased shares were retired. During the Current Period, the repurchases were accounted for as a decrease to paid-in-capital of $20.5 million and a decrease to Class A Common Stock of approximately $28,000. In the Prior Period, the Company repurchased 199,976 shares in connection with employee minimum tax withholding requirements.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT
FAIR VALUE MEASUREMENT	NOTE 11—FAIR VALUE MEASUREMENT The Company utilizes fair value measurements to measure assets and liabilities in a business combination or assess impairment and abandonment of property and equipment, intangible assets and goodwill or to measure the value of securities marked to market. 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 ASC 820 establishes a three-level valuation hierarchy for the 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 Level 2 Level 3 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 nine months ended September 30, 2022 or the year ended December 31, 2021. Nonmonetary transaction 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 September 30, 2022 and December 31, 2021, due to the short-term nature of these instruments. The Company did not have any bank debt as of September 30, 2022 or December 31, 2021. 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.

SIGNIFICANT ACCOUNTING POLICIES
Use of estimates	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 reserve, income taxes, self-insurance liabilities, share-based compensation, contingent liabilities, lease-related reasonably certain option exercise assessments, 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.
