Select Water Solutions Inc

NOTE 1—BUSINESS AND BASIS OF PRESENTATION

Description of the business: Select Water Solutions, Inc. (“we,” “Select Inc.,” “Select” or the “Company”), formerly Select Energy Services, Inc., was incorporated as a Delaware corporation on November 21, 2016. On May 8, 2023, Select Energy Services, Inc.’s Fifth Amended and Restated Certificate of Incorporation became effective upon filing with the Secretary of State of the State of Delaware which, among other things, changed the name of the company from Select Energy Services, Inc. to Select Water Solutions, Inc. to reflect its strategic focus as a water-focused company. We retained our stock ticker “WTTR” trading on the New York Stock Exchange. 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 sustainable water-management and chemical solutions to the energy industry in the United States (“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:*As of December 31, 2023, the Company had both Class A and Class B common shares issued and outstanding. Holders of shares of our Class A common stock, par value $0.01 per share (“Class A common stock”) and Class B common stock, par value $0.01 per share (“Class B common stock”) are entitled toone vote per share and vote together as a single class on all matters presented to our stockholders for their vote or approval.

*Exchange rights:*Under the Eighth Amended and Restated Limited Liability Company Agreement of SES Holdings (the “SES Holdings LLC Agreement”), SES Legacy Holdings LLC (“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 ofone 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.

Basis of presentation: The accompanying 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. The 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 December 31, 2023, the Company hadthree equity method investments. 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:

Dividends: During 2023, the Company paid $21.3 million in dividends accounted for as a reduction to additional paid in capital, $3.4 million of distributions accounted for as a reduction to noncontrolling interests and $0.2 million as a reduction to accrued expenses and other current liabilities. As of December 31, 2023, the Company had $0.8 million dividends payable included in accrued expenses and other current liabilities in connection with unvested restricted stock awards. All future dividend payments are subject to quarterly review and approval by the board of directors.

Segment reporting: The Company hasthree reportable segments. Reportable 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 reportable segments are Water Services, Water Infrastructure, and Chemical Technologies.

Effective June 1, 2023, our CODM began to strategically view and manage certain water sourcing and transfer operations, previously included in our Water Infrastructure segment, as part of our Water Services segment. These changes were driven by a number of factors, including the preponderance of our water sourcing business that integrates with our water transfer operations, the continued transition of completions water demand from fresh and brackish water to recycled water, as well, we anticipate more efficient sharing and utilization of resources and to realize potential synergies. Prior periods have been recast to include the water sourcing and transfer operations within the Water Services segment and remove the results of those operations from the Water Infrastructure segment.

Concurrently, the Company also decided to rename its Oilfield Chemicals segment as Chemical Technologies. This change was based on a number of factors, including the continued success of our chemicals business in delivering customized, specialty chemicals products developed through our own research and development efforts and the de-emphasis of certain traditional commoditized chemistry products within the oil and gas industry, as well as the continued investments in time and resources we make to manufacture and sell our specialty chemical products into non-oilfield industrial-related applications. We believe these segment changes better align the business with the current and future state of the Company’s operations and capital allocation and strategic objectives. This change was a naming convention only change that did not impact any numbers for all years presented.

The Water Services segment consists of the Company’s services businesses, including water sourcing, water transfer, flowback and well testing, fluids hauling, water monitoring, water containment and water network automation, primarily serving exploration and production (“E&P”) companies. Additionally, this segment includes the operations of our accommodations and rentals business.

The Water Infrastructure segment consists of the Company’s fixed infrastructure assets, including operations associated with our water distribution pipeline infrastructure, our water recycling solutions, and our produced water gathering systems and saltwater disposal wells, as well as solids disposal facilities, primarily serving E&P companies.

The Chemical Technologies segment provides technical solutions, products and expertise related to chemical applications in the oil and gas industry. We develop, manufacture, manage logistics and provide a full suite of chemicals used in hydraulic fracturing, stimulation, cementing and well completions for customers ranging from pressure pumpers

to major integrated and independent oil and gas producers. This segment also utilizes its chemical experience and lab testing capabilities to customize tailored water treatment solutions designed to optimize the fracturing fluid system in conjunction with the quality of water used in well completions.

Reclassifications: Certain reclassifications have been made to the Company’s prior period consolidated financial information to conform to the current year 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

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.

Cash and cash equivalents: The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

Accounts receivable: Accounts receivable are stated at the invoiced amount, or the earned but not yet invoiced amount, net of an allowance for credit losses.

*Allowance for credit losses:*The Company’s allowance for credit losses relates to trade accounts receivable. The Company treats trade accounts receivable as one portfolio and records an initial allowance calculated as a percentage of revenue recognized based on a combination of historical information and future expectations. Additionally, the Company adjusts this allowance based on specific information in connection with aged receivables. Historically, most bad debt has been incurred when a customer’s financial condition significantly deteriorates, which in some cases leads to bankruptcy. Market volatility is highly uncertain and, as such, the impact on expected losses is subject to significant judgment and may cause variability in the Company’s allowance for credit losses in future periods.

The change in the allowance for credit losses is as follows:

Concentrations of credit and customer risk: Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable. The amounts held in financial institutions periodically exceed the federally insured limit. Management believes that the financial institutions are financially sound and the risk of loss is minimal. The Company minimizes its exposure to counterparty credit risk by performing credit evaluations and ongoing monitoring of the financial stability of its customers. There wereno customers that accounted for more than 10% of the Company’s consolidated revenues or receivables for the years ended December 31, 2023, 2022 and 2021, respectively.

Inventories: The Company values its inventories at lower of cost or net realizable value. Inventory costs are determined under the weighted-average method. Inventory costs primarily consist of chemicals and materials available for resale and parts and consumables used in operations.

Property and equipment: Property and equipment are stated at cost less accumulated depreciation.

Depreciation (and amortization of finance lease assets) is calculated on a straight-line basis over the estimated useful life of each asset as noted below:

Depreciation expense related to the Company’s property and equipment, including amortization of property under finance leases, was $122.2 million, $103.3 million and $81.6 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Change in depreciable lives of property and equipment: In accordance with its policy, the Company reviews the estimated useful lives and estimated salvage values of its fixed assets on an ongoing basis.

*Business Combinations:*The Company records business combinations using the acquisition method of accounting. Under the acquisition method of accounting, identifiable assets acquired and liabilities assumed are recorded at their acquisition-date fair values. The excess of the purchase price over the estimated fair value is recorded as goodwill and the excess of the fair value over the purchase price is recorded as a bargain purchase gain. Changes in the estimated fair values of net assets recorded for acquisitions prior to the finalization of more detailed analysis, but not to exceed one year from the date of acquisition, will adjust the amount of the purchase price allocable to goodwill. Measurement period adjustments are reflected in the period in which they occur.

Other intangible assets: Other intangible assets not subject to amortization are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. Intangible assets with finite useful lives are amortized either on a straight-line basis over the asset’s estimated useful life or on a basis that reflects the pattern in which the economic benefits of the intangible assets are realized.

Impairment of long-lived assets and intangible assets: Long-lived assets, such as property and equipment and finite-lived intangible assets, are evaluated for impairment whenever events or changes in circumstances indicate that its carrying value may not be recoverable. Recoverability is measured by a comparison of its carrying amount to the estimated undiscounted cash flows to be generated by those assets. If the undiscounted cash flows are less than the

carrying amount, the Company records impairment losses for the excess of its carrying value over the estimated fair value. The development of future cash flows and the estimate of fair value represent its best estimates based on industry trends and reference to market transactions and are subject to variability. The Company considers the factors within the fair value analysis to be Level 3 inputs within the fair value hierarchy. See “Note 4—Abandonments and Other Costs” for further discussion.

Asset retirement obligations: The asset retirement obligation (“ARO”) liability reflects the present value of estimated costs of plugging, site reclamation and similar activities associated with the Company’s saltwater disposal wells. The Company utilizes current retirement costs to estimate the expected cash outflows for retirement obligations. The Company also estimates the productive life of the disposal wells, a credit-adjusted risk-free discount rate and an inflation factor in order to determine the current present value of this obligation. The Company’s ARO liabilities are included in accrued expenses and other current liabilities and other long-term liabilities as of December 31, 2023, and 2022.

The change in asset retirement obligations is as follows:

In addition to the obligations described above, the Company may be obligated to remove facilities or perform other remediation upon retirement of certain other assets. However, the fair value of the asset retirement obligation cannot currently be reasonably estimated because the settlement dates are indeterminable. If applicable, the Company will record an asset retirement obligation for these assets in the periods in which settlement dates are reasonably determinable.

Retentions: The Company assumes risk of loss through deductibles and self-insured retentions, up to certain levels for losses related to general liability, workers’ compensation and employer’s liability, vehicle liability and health insurance. The Company’s exposure (i.e., the self-insured retention or deductible) per occurrence is$0.5 million for general liability, $0.25 million for workers’ compensation and employer’s liability, $0.25 million for auto liability and $0.3 million for health insurance. We also have an excess loss policy over these coverages with a limit of $100.0 million in the aggregate. Management regularly reviews its estimates of reported and unreported claims and provide for losses through reserves. As of December 31, 2023, the Company estimated the range of exposure to be from $16.2 million to $19.2 million for worker’s compensation and auto liability claims and have recorded liabilities of $17.3 million, which represents management’s best estimate of probable loss related to these claims. Additionally, accrued health insurance and accrued general liabilities were $6.7 million and $1.3 million as of December 31, 2023, respectively. These liabilities are included in accrued insurance and other long-term liabilities depending on whether they are short or long-term in nature.

Defined Contribution Plan: The Company sponsors a defined contribution 401(k) Profit Sharing Plan (the “401(k) Plan”) for the benefit of substantially all employees of the Company. The 401(k) Plan allows eligible employees to make tax-deferred contributions, not to exceed annual limits established by the Internal Revenue Service. The vesting

schedule for new hires is 25% for the first year,50% for the second year,75% for the third year and 100% for the fourth year.

Effective July 1, 2021, the Company matched contributions of 50% of employee contributions, up to 4% of eligible earnings. Effective October 1, 2022, the Company began matching contributions of 100% of employee contributions, up to 4% of eligible earnings. The Company’s costs related to the 401(k) Plan match were $6.2 million, $3.1 million and $0.1 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Revenue recognition: The Company follows ASU 2014-09,*Revenue from Contracts with Customers (Topic 606).See “Note 5—Revenue” for further detail on applying this standard.*The Company uses the five step process to recognize revenue which entails (i) identifying contracts with customers; (ii) identifying the performance obligations in each contract; (iii) determining the transaction price; (iv) allocating the transaction price to the performance obligations; and (v) recognizing revenue as we satisfy performance obligations. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services transferred to the customer. Revenue from the Company’s Water Services and Water Infrastructure segments is typically recognized over the course of time, whereas revenue from the Company’s Chemical Technologies segment is typically recognized upon change in control. Revenue generated by each of the Company’s revenue streams are outlined as follows:

Water Services and Water Infrastructure—The Company provides water-related services to customers, including the sourcing and transfer of water, produced water gathering, treatment and reuse, the containment of fluids, measuring and monitoring of water, the filtering and treatment of fluids, well testing and handling, transportation and recycling or disposal of fluids. The Company recognizes revenue as services are performed.

The Company’s agreements with its customers are often referred to as “price sheets” and sometimes provide pricing for multiple services. However, these agreements generally do not authorize the performance of specific services or provide for guaranteed throughput amounts. As customers are free to choose which services, if any, to use based on the Company’s price sheet, the Company prices its separate services on the basis of their standalone selling prices. Customer agreements generally do not provide for performance-, cancellation-, termination-, or refund-type provisions. Services based on price sheets with customers are generally performed under separately-issued “work orders” or “field tickets” as services are requested. Multiple service lines of the Company’s Water Services and Water Infrastructure segments are sometimes part of the same arrangement. In these instances, revenue for the applicable service lines are recognized concurrently when delivered. Additionally, asset rentals are recognized on a straight-line basis.

**Chemical Technologies Product Sales—**The Company develops, manufactures and markets a full suite of chemicals utilized in hydraulic fracturing, stimulation, cementing and well completions, including polymers that create viscosity, crosslinkers, friction reducers, surfactants, buffers, breakers and other chemical technologies, to leading pressure pumping service companies in the U.S. The Company also provides production chemicals solutions, which are applied to underperforming wells in order to enhance well performance and reduce production costs through the use of production treating chemicals, corrosion and scale monitoring, chemical inventory management, well failure analysis and lab services.

Chemical Technologies products are generally sold under sales agreements based upon purchase orders or contracts with customers that do not include right of return provisions or other significant post-delivery obligations. The Company’s products are produced in a standard manufacturing operation, even if produced to the customer’s specifications. The prices of products are fixed and determinable and are established in price lists or customer purchase orders. The Company recognizes revenue from product sales when title passes to the customer, the customer assumes risks and rewards of ownership, collectability is reasonably assured and delivery occurs as directed by the customer.

Equity-based compensation: The Company accounts for equity-based awards for restricted stock awards, restricted stock units, and stock-settled appreciation awards by measuring the awards at the date of grant and recognizing the grant-date fair value as an expense using either straight-line or accelerated attribution, depending on the specific

terms of the award agreements over the requisite service period, which is usually equivalent to the vesting period. The Company expenses awards with graded-vesting service conditions on a straight-line basis and accounts for forfeitures as they occur. The Company accounts for performance share units by remeasuring the awards at the end of each reporting period based on the period-end closing share price, factoring in the percentage expected to vest, and the percentage of the service period completed.

Fair value measurements: The Company measures certain assets and liabilities pursuant to accounting guidance, which establishes a three-tier fair value hierarchy and prioritizes the inputs used in measuring fair value. Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 inputs are quoted prices or other market data for similar assets and liabilities in active markets, or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3 inputs are unobservable inputs based upon the Company’s own judgment and assumptions used to measure assets and liabilities at fair value. See “Note 13—Fair Value Measurement” for further discussion.

Income taxes: Select Inc. is subject to U.S. federal, foreign and state income taxes as a corporation. SES Holdings and its subsidiaries, with the exception of certain corporate subsidiaries, are treated as flow-through entities for U.S. federal income tax purposes and as such, are generally not subject to U.S. federal income tax at the entity level. Rather, the tax liability with respect to their taxable income is passed through to their members or partners. Select Inc. recognizes a tax liability on its allocable share of SES Holdings’ taxable income. The state of Texas includes in its tax system a franchise tax applicable to the Company and an accrual for franchise taxes is included in the financial statements when appropriate.

The Company and its subsidiaries account for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled pursuant to the provisions of Accounting Standards Codification (“ASC”) 740, Income Taxes. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized.

The determination of the provision for income taxes requires significant judgment, use of estimates and the interpretation and application of complex tax laws. Significant judgment is required in assessing the timing and amounts of deductible and taxable items and the probability of sustaining uncertain tax positions. The benefits of uncertain tax positions are recorded in the Company’s financial statements only after determining a more likely than not probability that the uncertain tax positions will withstand challenge, if any, from taxing authorities. When facts and circumstances change, the Company reassesses these probabilities and records any changes through the provision for income taxes. The Company recognizes interest and penalties relating to uncertain tax provisions as a component of tax expense. The Company identified no material uncertain tax positions as of December 31, 2023, 2022 and 2021. See “Note 15—Income Taxes” for further discussion.* *

Tax Receivable Agreements: In connection with the Select 144A Offering, the Company 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”). The 144A Offering represented a reorganization transaction between entities under common control and was recorded based on the historical carrying amounts of affected assets and liabilities in accordance with ASC 805-50, Business Combinations – Related Issues. Accordingly, the Tax Receivable Agreements liabilities are accounted for in accordance with ASC 450, Contingencies, on a gross undiscounted basis, for amounts payable under the provisions of the Tax Receivable Agreements that have been determined to be probable of occurring for amounts that are reasonably estimable. Changes in estimated Tax Receivable Agreements liabilities are recognized as tax receivable agreements expense on the consolidated statements of operations. Additionally, following the Company’s acquisition (or deemed acquisition for U.S. federal income tax purposes) of all or a portion of a TRA Holder’s SES Holdings LLC Units pursuant to the exercise of the Exchange Right or the Company’s Call Right, the Company records obligations under the Tax Receivable Agreements at the gross undiscounted amount as an increase to the liability with

an offset to additional paid-in capital for the amount of expected future payments that are determined to be probable of occurring for amounts that are reasonably estimable.

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.

The second of the Tax Receivable Agreements, which the Company entered into with an affiliate of Legacy Owner Holdco and 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) any net operating losses available to the Company as a result of certain reorganization transactions entered into in connection with the Select 144A Offering and (ii) imputed interest deemed to be paid by the Company as a result of any payments the Company makes under such Tax Receivable Agreement

The Company will retain the benefit of the remaining 15% of these cash savings. Based upon the Company’s historical, current and anticipated future earnings trends and other matters described in Note 15 – Income Taxes, as of December 31, 2023, the Company determined that it was in a position to reasonably estimate the amount of the liability associated with the Tax Receivable Agreements and determined that future payments under the terms of the Tax Receivable Agreements were probable, and therefore recorded liabilities of $38.2 million as of December 31, 2023. Prior to this, the Company had determined that it was not in a position to reasonably estimate such amount and that future payments were not probable. See “Note 15 – Income Taxes and Note 14 – Related Party Transactions” for further discussion. The projection of future taxable income and utilization of tax attributes associated with the Tax Receivable Agreements involve estimates which require significant judgment. The amount of the Company’s actual taxable income, passage of future legislation, or consummation of significant transactions in the future may significantly impact the liability related to the Tax Receivable Agreements.

*Realizability of Deferred Tax Assets:We establish valuation allowances when necessary to reduce deferred tax assets to the amounts more likely than not to be realized. Deferred income tax assets are evaluated quarterly to determine if valuation allowances are required or should be adjusted. The ability to realize deferred tax assets depends on the ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction. The assessment regarding whether a valuation allowance is required or should be adjusted is based on an evaluation of possible sources of taxable income and also considers all available positive and negative evidence factors. Our accounting for the realization of deferred tax assets incorporates, amongst other factors, our best estimate of future events. Changes in our current estimates, due to unanticipated market conditions, governmental legislative actions or events, could have a material effect on our ability to utilize deferred tax assets. As of December 31, 2023, valuation allowances against deferred tax assets were $112 million. See “Note 15—Income Taxes” for additional information. *

Recent accounting pronouncements: In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. As the London Interbank Offered Rate ("LIBOR") was no longer available beginning July 2023, this standard update provided practical expedients for contract modifications made as part of the transition from LIBOR to alternative reference rates. The guidance was effective upon issuance and at present can generally be applied through December 31, 2024. The Company adopted this ASU in the Current Period, and it had no impact on the consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss, and the title and position of the entity’s CODM. The amendments in this update also expand the interim segment disclosure requirements. ASU 2023-07 will be effective for our fiscal year ending December 31, 2024, and for interim periods starting in our first quarter of 2025. Early adoption is permitted and the amendments in this update are required to be applied on a retrospective basis. We are currently reviewing the impact that the adoption of ASU 2023-07 may have on our consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 will be effective for our fiscal year ending December 31, 2025 with early adoption permitted, and should be applied either prospectively or retrospectively. The Company is currently evaluating the ASU to determine its impact on the Company’s disclosures.

NOTE 3—ACQUISITIONS

The following table presents key information connected with our 2023, 2022 and 2021 acquisitions (dollars in thousands, except share amounts):

2023 Asset Acquisitions

During the year ended December 31, 2023, Select acquired certain assets, revenue-producing contracts and associated liabilities, primarily in the Permian Basin, from multiple entities for $17.7 million inclusive of $0.2 million of acquisition-related costs. The allocation of the purchase price for these assets was a combined $15.9 million in property and equipment, $1.0 million in water inventory, $1.9 million in customer relationships and $1.1 million in asset retirement obligations and other liabilities. Many of the assets acquired are adjacent to the Company’s Big Spring Recycling System (“BSRS”), with connectivity into BSRS providing future revenue and cost synergies.

Breakwater Acquisition

On November 1, 2022, the Company completed the acquisition of Breakwater Energy Services, LLC. (“Breakwater”) in a stock-for-stock transaction for total consideration of $105.3 million based on the closing price of the Company’s shares of Class A common stock on October 31, 2022 (the “Breakwater Acquisition”). The consideration transferred consisted of 9,181,144 shares of Class A common stock, $10.5 million of debt that was paid off at closing as part of consideration exchanged, $3.8 million in change-of-control payments and $2.4 million in seller transaction costs. The acquisition strengthened Select’s geographic footprint with a unique set of water logistics and infrastructure assets, particularly in the Permian region.

The Breakwater 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 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, intangible assets, current assets, current liabilities and long-term liabilities were finalized as of September 30, 2023. The total consideration paid exceeded the fair value of the net assets acquired by $4.7 million, with the excess recorded as goodwill. The goodwill recognized was driven primarily by the ability to connect Breakwater’s infrastructure with the Company’s infrastructure and expand revenue-producing capabilities and market share. The acquired goodwill is deductible for tax purposes. The assets acquired and liabilities assumed are included in the Company’s Water Services and Water Infrastructure segments. The Company incurred $2.1 million and $2.9 million of transaction-related costs related to this acquisition during the year ended December 31, 2023, and during the year ended December 31, 2022, 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 as of the date of acquisition:* *

Big Spring Recycling System Noncontrolling Interests

In connection with Select’s acquisition of Breakwater on November 1, 2022, Select acquired all noncontrolling interests in the Big Spring Recycling System (“BSRS”) on December 2, 2022. BSRS includes significant pipeline, storage, recycling and disposal infrastructure assets in the Midland Basin. The consideration paid included $7.3 million based on the closing price of the Company’s shares of Class A common stock on December 1, 2022, and $22.0 million in cash for total consideration of $29.3 million. The consideration transferred included 910,612 shares of Class A common stock. This equity transaction enabled Select to simplify the BSRS operations and decision-making processes and provided potential revenue and cost synergies. This transaction was accounted for primarily as a reduction of noncontrolling interests.

2022 Asset Acquisition

On December 2, 2022, Select acquired certain assets and revenue-producing contracts in the Midland Basin from an entity for $6.1 million inclusive of $0.1 million of acquisition-related costs. The asset acquisition allocation was $3.9 million in property and equipment and $2.2 million in customer relationships. Many of the assets acquired are adjacent to the BSRS, with connectivity into the BSRS providing future revenue and cost synergies.

Cypress Acquisition

On November 1, 2022, the Company completed the acquisition of certain saltwater disposal assets from Cypress Environmental Solutions, LLC (“Cypress”) for total consideration of $9.2 million based on the closing price of the Company’s shares of Class A common stock on October 31, 2022 (the “Cypress Acquisition”). The consideration transferred consisted of 952,753 shares of Class A common stock. The acquired Cypress operations consist ofeight saltwater disposal facilities with daily permitted capacity of 85,000 barrels per day across North Dakota. The acquisition strengthened Select’s geographic footprint with a portfolio of strategic wastewater disposal facilities in the Bakken region, with the majority of Cypress’s volumes being delivered through high volume contracted gathering pipeline infrastructure.

The Cypress 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 March 31, 2023. The assets acquired and liabilities assumed are included in the Company’s Water Infrastructure segment. The Company incurred less than $0.1 million and $0.5 million of transaction-related costs related to this acquisition during the year ended December 31, 2023, and during the year ended December 31, 2022, respectively, and such costs are included in selling, general and administrative within the consolidated statements of operations.

Nuverra Acquisition

On February 23, 2022, the Company completed the acquisition of Nuverra Environmental Solutions, Inc. (“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”).

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 resulted in a bargain purchase gain, 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 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 December 31, 2022. The Nuverra debt, including accrued interest, totaled $18.8 million, and was repaid during the year ended December 31, 2022, after the acquisition was completed. The assets acquired and liabilities assumed are included in the Company’s Water Services and Water Infrastructure segments.

NOTE 4—ABANDONMENTS AND OTHER COSTS

On February 21, 2023, the Company announced a rebranding initiative that occurred during the first half of 2023. As a result of this initiative, our existing trademarks are no longer considered indefinite-lived and will be measured for abandonment whenever events or changes in circumstances indicate that its carrying value may not be recoverable. The rebranding announcement qualified as a triggering event, and the Company tested the existing trademarks for abandonment. This evaluation included significant judgment, including discount rates based on our weighted-average cost of capital and the royalty rate. This resulted in $11.1 million of abandonment expense to trademarks using the relief-from-royalty method, which was recorded in the Chemical Technologies segment within impairments and abandonments on the accompanying consolidated statements of operations.

A summary of impairments to and abandonment of property and equipment for the years ended December 31, 2023, 2022 and 2021 is as follows:

A summary of severance and lease abandonment costs for the years ended December 31, 2023, 2022 and 2021 is as follows:

During the year ended December 31, 2021, the Company incurred $3.2 million of severance cost in connection with the termination of its former chief executive officer, which was paid in full during 2021.

NOTE 5—REVENUE

The Company follows ASU 2014-09,Revenue from Contracts with Customers (Topic 606), for most revenue recognition, which 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 applies the five-step model only 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 accommodations and rentals revenue continues to be guided by ASC 842 –Leases, which is discussed further below.

The following factors are applicable to allthree of the Company’s segments for the years 2023, 2022 and 2021, respectively:

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 the output generated, which is usually simultaneously received and consumed by customers at their job sites. As a multi-job site organization, contract terms, including the 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 December 31, 2023, the Company hadfifteen contracts lasting over one year that include enforceable rights and obligations to fall within the scope of the model in the Topic 606 standard. As of December 31, 2023, the Company hadno contract assets or contract liabilities.

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 December 31, 2023, there were no material rental agreements in effect lasting more than one year. During 2023, 2022 and 2021, approximately $83.3 million, $75.9 million and $31.4 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 Chemical Technologies 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 December 31, 2023 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:

In the Water Services segment, the most recent topthree revenue-producing regions are the Permian Basin, Marcellus/Utica and Rockies, which collectively comprised 70%,68% and 71% of segment revenue for 2023, 2022 and 2021, respectively. In the Water Infrastructure segment, the most recent topthree revenue-producing regions are the Permian Basin, Bakken and Haynesville/E. Texas, which collectively comprised 78%,82% and 76% of segment revenue for 2023, 2022 and 2021, respectively. In the Chemical Technologies segment, the most recent topthree revenue-producing regions are the Permian Basin, Midcon and Rockies, which collectively comprised 86%,76% and 68% of segment revenue for 2023, 2022 and 2021, respectively.

NOTE 6—LEASES

As of December 31, 2023, the Company was the lessee for 367 operating leases with durations greater than a year,15 subleases,76 finance leases, and is the lessor fortwo owned properties. Most of the operating leases either have renewal options of betweenone andfive years or convert to month-to-month agreements at the end of the specified lease term.

The Company’s operating leases are primarily for (i) housing personnel for operations, (ii) operational yards for storing and staging equipment, (iii) vehicles and equipment used in operations, (iv) facilities used for back-office functions and (v) equipment used for back-office functions. 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, some of which continue in perpetuity until the lessor or the Company terminates the lease agreement. The majority of the Company’s lease expenses are in connection with short-term agreements, including expenses incurred hourly, daily, monthly and for other durations of time of one year or less. Due to the volatility of the price of a barrel of oil and the short-term nature of the vast majority of customer agreements, the Company must have flexibility to continuously scale operations at multiple locations. Consequently, the Company avoids committing to long-term agreements with numerous equipment rentals, vehicle fleet agreements and man-camp agreements, unless a business case supports a longer term agreement. Consequently, the Company’s future lease commitments as of December 31, 2023 do not reflect all of the Company’s short-term lease commitments.

Certain short-term and month-to-month vehicle and equipment leases have residual value guarantees if the Company decides to turn in vehicles and equipment before the end of the lease term. Vehicles and equipment turned in early result in sale proceeds, which have historically been equal to or greater than the residual value guarantees. There are no residual value guarantees if the vehicles or equipment is fully paid off.

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’s lease arrangements may contain both lease and non-lease components. The Company has elected to combine and account for lease and non-lease components as a single lease component for its leases.

The Company’s variable lease costs are comprised of variable royalties, variable common area maintenance, and variable reimbursement of lessor insurance and property taxes. Variable lease costs were $1.7 million, $1.3 million and $1.3 million during the years ended December 31, 2023, 2022 and 2021, respectively. Property tax expense of $1.1 million, $0.8 million and $0.8 million for the years ended December 31, 2023, 2022 and 2021, respectively, is included in variable lease costs, but excluded from the lease expense referenced in the table below.

The lease disclosures in this “Note 6—Leases” exclude revenue governed by the lease standard associated with the Company’s accommodations and rentals business, as all customer agreements are short-term. See “Note 5—Revenue” for a comprehensive discussion on revenue recognition.

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

The Company has the following operating and finance lease commitments as of December 31, 2023:

NOTE 7—INVENTORIES

Inventories, which are comprised of chemicals and raw materials available for resale and parts and consumables used in operations, are valued at the lower of cost and net realizable value, with cost determined under the weighted-average method. The significant components of inventory are as follows:

During the year ended December 31, 2023, the Company recorded charges to the reserve for excess and obsolete inventory of$2.3 million. During the year ended December 31, 2022, the Company recorded net credits to the reserve for excess and obsolete inventory of $0.7 million. Both credits and charges to the reserve for excess and obsolete inventory were recognized within costs of revenue on the accompanying consolidated statements of operations. The Company’s inventory reserve was $5.5 million and $3.1 million as of the years ended December 31, 2023 and December 31, 2022, respectively. The reserve for excess and obsolete inventories is determined based on the Company’s historical usage of inventory on hand, as well as future expectations, and the amount necessary to reduce the cost of the inventory to its estimated net realizable value.

NOTE 8—PROPERTY AND EQUIPMENT

Property and equipment consists of the following as of December 31, 2023 and 2022:

Total depreciation and amortization expense related to property and equipment and finance leases presented in the table above, as well as amortization of intangible assets presented in “Note 9—Goodwill and Other Intangible Assets” is as follows:

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. See “Note 4—Abandonments and Other Costs” for impairment and abandonment of property and equipment during the years ended December 31, 2023, 2022 and 2021.

NOTE 9—GOODWILL AND OTHER INTANGIBLE ASSETS

The Company recorded $4.7 million of goodwill in connection with the Breakwater Acquisition during the year ended December 31, 2023. See “Note 3—Acquisitions*”* for* *additional information. Goodwill is evaluated for impairment annually, or more frequently if indicators of impairment exist. The annual impairment tests are based on Level 3 inputs (see “Note 13—Fair Value Measurement”). During the fourth quarter of 2023, the Company performed its annual impairment test of goodwill and determined there was no impairment of the carrying value of goodwill.

The changes in the carrying amounts of goodwill by reportable segment for the year ended December 31, 2023 and 2022 is as follows:

The components of other intangible assets as of December 31, 2023 and 2022 are as follows:

For a discussion of the abandonment of the trademark, See “Note 4—Abandonments and Other Costs.”

During the year ended December 31, 2023, the Company added $6.4 million in customer relationships in connection with finalizing the Breakwater purchase price allocation and an asset acquisition adjacent to the BSRS facility. During the year ended December 31, 2022, the Company added $41.7 million in customer relationships in connection with the Breakwater, Cypress and asset acquisition adjacent to the BSRS facility (See “Note 3—Acquisitions”). The weighted-average amortization period for customer relationships, patents and other intellectual property and other definite-lived intangible assets as of December 31, 2023 was 9.1 years,4.6 years and 0.7 years, respectively.

The indefinite-lived water rights andtrademarks are generally subject to renewal every five toten years.

Amortization expense of $17.9 million, $11.4 million and $10.6 million was recorded for the years ended December 31, 2023, 2022 and 2021, respectively. Annual amortization of intangible assets for the next five years and beyond is as follows:

NOTE 10—DEBT

Sustainability-linked credit facility and revolving line of credit

On March 17, 2022 (the “Restatement Date”), SES Holdings and Select Water Solutions, LLC (“Select LLC”), formerly Select Energy Services, LLC and a wholly-owned subsidiary of SES Holdings, entered into a $270.0 million amended and restated senior secured sustainability-linked revolving credit facility (the “Sustainability-Linked Credit Facility”), 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”) (which amended and restated the Credit Agreement dated November 1, 2017 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 the Administrative Agent (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) 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.

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.

The Company hadzero and $16.0 million outstanding under the Sustainability-Linked Credit Facility as of December 31, 2023 and December 31, 2022, respectively. As of December 31, 2023 and December 31, 2022, the borrowing base under the Sustainability-Linked Credit Facility was $267.4 million and $245.0 million, respectively. The borrowing capacity under the Sustainability-Linked Credit Facility was reduced by outstanding letters of credit of $17.1 million and $22.9 million as of December 31, 2023 and December 31, 2022, respectively. The Company’s letters of credit have a variable interest rate between 1.75% and 2.25% based on the Company’s average excess availability as outlined above. The unused portion of the available borrowings under the Sustainability-Linked Credit Facility was $250.3 million as of December 31, 2023.

In connection with the entry into the Sustainability-Linked Credit Facility, the Company incurred $2.1 million of debt issuance costs during the year ended December 31, 2022. 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 December 31, 2023 and December 31, 2022, were $1.6 million and $2.1 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 $0.5 million, $0.7 million and $0.7 million for the years ended December 31, 2023, 2022 and 2021, respectively.

The Company was in compliance with all debt covenants as of December 31, 2023.

NOTE 11—COMMITMENTS AND CONTINGENCIES

Litigation

NOTE 12—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 1.9 million shares available to be issued as of December 31, 2023. For all share-based compensation award types, the Company accounts for forfeitures as they occur.

On February 23, 2022, the Company assumed the Nuverra Environmental Solutions, Inc. 2017 Long Term Incentive Plan (the “2017 Plan”), and the Nuverra Environmental Solutions, Inc. 2018 Restricted Stock Plan for Directors (the “2018 Plan” and, together with the 2017 Plan, the “Assumed Plans”) and certain equity awards outstanding under the Assumed Plans in connection with the Nuverra Acquisition. Under the 2017 Plan, the Company may grant to certain eligible participants who were employees, directors or other service providers of Nuverra prior to the Nuverra Acquisition options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, other stock-based awards, cash awards, substitute awards, performance awards, or any combination of the foregoing, with respect to up to 1,772,058 shares of Nuverra common stock. Under the 2018 Plan, the Company may grant to certain eligible participants who were directors of Nuverra prior to the Nuverra Acquisition restricted stock awards with respect to up to 100,000 shares of Nuverra common stock. The shares remaining available for issuance under the Assumed Plans were converted into shares of the Company’s Class A common stock at a conversion rate ofone Nuverra share to 0.2551 shares of the Company’s Class A common stock such that at the time of the Nuverra Acquisition an aggregate of 131,110 shares of the Company’s Class A common stock was available for issuance with respect to assumed awards and future awards under the 2017 Plan and an aggregate of 24,984 shares of the Company’s Class A common stock was available for issuance with respect to assumed awards and future awards under the 2018 Plan. No awards have been granted under these legacy Nuverra Assumed Plans.

The aggregate number of shares of the Company’s Class A common stock available for issuance under the Assumed Plans will be reducedbyone share of the Company’s Class A common stock for every one share of the Company’s Class A common stock subject to an award granted under the Assumed Plans. If any award granted under the 2017 Plan (in whole or in part) is cancelled, forfeited, exchanged, settled in cash, or otherwise terminated, the shares of the Company’s Class A common stock subject to such award will again be available at a rate ofone share of the Company’s Class A common stock for every one share of the Company’s Class A common stock subject to such award, and if any award granted under the 2018 Plan (in whole or part) is forfeited, the shares of the Company’s Class A common stock subject to such award will again be available at a rate ofone share of the Company’s Class A common stock for every one share of the Company’s Class A common stock subject to such award. The Company registered the securities issuable under the Assumed Plans by filing a registration statement on Form S-8 with the Securities and Exchange Commission on February 23, 2022. As of December 31, 2023, the maximum number of shares of the Company’s Class A common stock available for future issuance under the 2017 Plan is 55,769 and under the 2018 Plan is 14,736.

Stock Option Awards

The Company has outstanding stock option awards as of December 31, 2023 but there have beenno 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 Company utilized the Monte Carlo option pricing model to determine fair value of the options granted during 2018, which incorporated 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 at the time of the grant was based on the vesting period and term of the options awarded, which wasten years.

A summary of the Company’s stock option activity and related information as of and for the year ended December 31, 2023 is as follows:

The Company recognized $0, $0, and a nominal amount of compensation expense related to stock options during the years ended December 31, 2023, 2022 and 2021, respectively. As of December 31, 2021, 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 generallyone tothree years from the applicable date of grant. The Company recognized compensation expense of $16.8 million, $14.3 million and $7.9 million related to the restricted stock awards for the years ended December 31, 2023, 2022 and 2021, respectively. As of December 31, 2023, there was $13.1 million of unrecognized compensation expense with a weighted-average remaining life of 1.7 years related to unvested restricted stock awards. During 2023 and 2022, the Company paid $4.3 million and $4.4 million, respectively, to repurchase shares in connection with employee minimum tax withholding obligations on vested shares.

A summary of the Company’s restricted stock awards activity and related information for the year ended December 31, 2023 is as follows:

Performance Share Units (“PSUs”)

During 2021, 2022 and 2023, 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, 2021 through December 31, 2023, January 1, 2022 through December 31, 2024 or January 1, 2023 through December 31, 2025.

The target number of shares of Class A common stock subject to each remaining PSU granted in 2021, 2022 and 2023 isone; 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, 2024 for the 2021 PSU grants, June 30, 2025 for the 2022 PSU grants, and June 30, 2026, for the 2023 PSU grants, assuming the applicable minimum performance metrics are achieved.

The target PSUs granted in 2021, 2022 and 2023 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 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, the 2021 2022 and 2023 PSUs will be valued each reporting period utilizing a Black-Scholes model.

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:

The fair value on the date the PSUs were granted during 2023, 2022 and 2021 was $5.3 million, $5.0 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 $0.6 million, $1.3 million, and $1.6 million related to the PSUs for the years ended December 31, 2023, 2022 and 2021, respectively.

As of December 31, 2023, the unrecognized compensation cost related to our unvested PSUs is estimated to be$4.4 million and is expected to be recognized over a weighted-average period of 1.8 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 December 31, 2023:

Employee Stock Purchase Plan (ESPP)

The Company formerly had an Employee Stock Purchase Plan (“ESPP”) under which employees that have been continuously employed for at leastone year may purchase shares of Class A common stock at a discount. On November 3, 2022, our board of directors approved an amendment to the ESPP, which suspended all offerings on or after December 1, 2022. Our board of directors reserves the right to recommence offerings pursuant to its discretion and the terms of the ESPP.

Share-repurchases

During the years ended December 31, 2023 and 2022, the Company repurchased 8,050,282 and 2,297,985 shares, respectively, of Class A common stock in the open market and repurchased 567,702 and 524,562 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. During the year ended December 31, 2023, the repurchases were accounted for as a decrease to paid in-capital of $61.7 million and a decrease to Class A common stock of approximately $86,000.

The Inflation Reduction Act of 2022 (“IRA 2022”) provides for, among other things, the imposition of a new 1% U.S. federal excise tax on certain repurchases of stock by publicly traded U.S. corporations such as us after December 31, 2022. Accordingly, this excise tax applied to our share repurchase program in 2023 and will apply in subsequent taxable years. The Biden administration has proposed increasing the amount of the excise tax from 1% to 4%; however, it is unclear whether such a change in the amount of the excise tax will be enacted and, if enacted, how soon any such change could take effect.

NOTE 13—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, 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 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—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 wereno transfers into, or out of, the three levels of the fair value hierarchy for the years ended December 31, 2023, 2022 and 2021.

Assets and liabilities measured at fair value on a recurring and non-recurring basis

Nonfinancial assets and liabilities measured at fair value on a non-recurring basis include certain nonfinancial assets and liabilities as may be acquired in a business combination or asset acquisition and measurements of goodwill and intangible impairment. As there is no corroborating market activity to support the assumptions used, the Company has designated these measurements as Level 3.

Long-lived assets, such as property and equipment and finite-lived intangible assets, are evaluated for impairment whenever events or changes in circumstances indicate that its carrying value may not be recoverable. The development of future cash flows and the estimate of fair value represent the Company’s best estimates based on industry trends and reference to market transactions and are subject to variability.

The Company’s estimates of fair value have been determined at discrete points in time based on relevant information. These estimates involve uncertainty and cannot be determined with precision. There were no significant changes in valuation techniques or related inputs for the years ended December 31, 2023, 2022 and 2021.

The following table presents information about the Company’s assets measured at fair value on a recurring and non-recurring basis for the years ended December 31, 2023, 2022 and 2021.

Nonmonetary transaction: During the year ended December 31, 2020, the Company had a nonmonetary exchange with a customer whereby the customer settled a $1.6 million accounts receivable balance using its restricted common stock, warrants and other privately traded securities. The Company elected the fair value option to account for the securities using a Level-2 calculation during the third quarter of 2020 with the value of the restricted stock and warrants derived from quoted active market pricing of unrestricted, publicly-traded, common stock and warrants and the value of the other privately traded securities was derived from a correlation with observable market data. The Company chose the fair value option to account for the securities because it represents the period-end value of the securities, which the Company has the ability to sell. The registration statement registering the resale of the restricted common stock, warrants and other privately traded securities received became effective in the fourth quarter of 2020. Accordingly, the Company used a Level-1 calculation during the fourth quarter of 2020 and throughout 2021 and 2022 with the value of the securities derived from quoted market pricing of unrestricted, publicly-traded securities.

The Company sold most of these securities during 2021 for $2.3 million, and recorded a $1.0 million realized gain during the year ended December 31, 2021 recognized within other income (expense), net on the accompanying consolidated statements of operations. The Company recorded a $2.0 million unrealized loss on the securities during the years ended December 31, 2021, based on the value of the securities as of the end of each reporting period within the year, recognized within other income (expense), net on the accompanying consolidated statements of operations. The remaining securities expired during the third quarter of 2022 resulting in a realized loss of $0.1 million recognized within other income (expense), net on the accompanying consolidated statements of operations.

Other fair value considerations

Also, see “Note 3—Acquisitions” for a discussion of the fair value incorporated into the purchase price allocation for acquisitions occurring during the years ended December 31, 2023, 2022 and 2021.

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 December 31, 2023 and 2022 due to the short-term nature of these instruments. The Company hadno outstanding debt as of December 31, 2023. The carrying value of debt as of December 31, 2022 approximates fair value due to variable market rates of interest. 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.

NOTE 14—RELATED PARTY TRANSACTIONS

The Company considers its related parties to be those stockholders who are beneficial owners of more than 5.0% of its common stock, executive officers, members of its board of directors or immediate family members of any of the foregoing persons, an investment in a company that is significantly influenced by another related party, and cost-method and equity-method investees. The Company has entered into a number of transactions with related parties. In accordance with the Company’s related persons transactions policy, the audit committee of the Company’s board of directors regularly reviews these transactions. However, the Company’s results of operations may have been different if these transactions were conducted with non-related parties.

During the year ended December 31, 2023, sales to related parties were $0.6 million and purchases from related-party vendors were $16.6 million. These purchases consisted of $12.6 million relating to the rental of certain equipment or other services used in operations, $2.6 million related to purchases of property and equipment, $1.3 million relating to management, consulting and other services and $0.1 million related to inventory and other consumables.

During the year ended December 31, 2022, sales to related parties were $2.1 million and purchases from related-party vendors were $12.4 million. These purchases consisted of $10.2 million relating to the rental of certain equipment or other services used in operations, $1.2 million relating to management, consulting and other services, $0.9 million related to purchases of property and equipment and $0.1 million related to inventory and other consumables.

During the year ended December 31, 2021, sales to related parties were $1.1 million and purchases from related-party vendors were $7.0 million. These purchases consisted of $5.8 million relating to the rental of certain equipment or other services used in operations, $1.0 million relating to management, consulting and other services and $0.2 million related to purchases of property and equipment.

Tax Receivable Agreements

In connection with the Select 144A Offering, the Company entered into the Tax Receivable Agreements with certain then-affiliates of the then-holders of SES Holdings LLC Units. As of December 31, 2023, certain of the TRA Holders were employed by the Company, on the Company’s board of directors and/or owned shares of the Company’s Class A and/or Class B common stock.

The first of the Tax Receivable Agreements, which the Company entered into with Legacy Owner Holdco and 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.

The second of the Tax Receivable Agreements, which the Company entered into with an affiliate of Legacy Owner Holdco and 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) any net operating losses available to the Company as a result of certain reorganization transactions entered into in connection with the Select 144A Offering and (ii) imputed interest deemed to be paid by the Company as a result of any payments the Company makes under such Tax Receivable Agreement.

On June 23, 2023, the Tax Receivable Agreements were amended to replace references to one year LIBOR with references to the 12-month term SOFR published by CME Group Benchmark Administration Limited plus 171.513 basis points, which is the benchmark replacement rate and additional margin that, under the Adjustable Interest Rate (LIBOR) Act of 2021, would have otherwise been inserted in place of references to LIBOR in the Tax Receivable Agreements following June 30, 2023.

The Company has recognized a liability associated with the Tax Receivable Agreements as of December 31, 2023 of $38.2 million. The liability is based on the actual cash tax savings expected to be realized by the Company, and the likelihood of a payment to be made under the Tax Receivable Agreements has been determined to be probable as of December 31, 2023. See “Note 15 – Income Taxes” below for additional information.

NOTE 15—INCOME TAXES

Select Inc. is subject to U.S. federal and state income taxes as a corporation. SES Holdings and its subsidiaries, with the exception of certain corporate subsidiaries, are treated as flow-through entities for U.S. federal income tax purposes and as such, are generally not subject to U.S. federal income tax at the entity level. Rather, the tax liability with respect to their taxable income is passed through to their members or partners. Select Inc. recognizes a tax liability on its allocable share of SES Holdings’ taxable income.

The Company’s effective tax rates for the years ended December 31, 2023, 2022 and 2021 were (316.4%),1.7% and (0.3%) respectively. The effective tax rates for the years ended December 31, 2023, 2022 and 2021 differ from the statutory rate of 21% for 2023, 2022 and 2021 due to net income allocated to noncontrolling interests, state income taxes and valuation allowances.

The components of the federal and state income tax (benefit) expense are summarized as follows:

A reconciliation of the Company’s provision for income taxes as reported and the amount computed by multiplying income before taxes, less noncontrolling interest, by the U.S. federal statutory rate of 21% for 2023, 2022 and 2021 is as follows:

Deferred taxes result from the temporary differences between financial reporting carrying amounts and the tax basis of existing assets and liabilities. As of December 31, 2023, and 2022, the Company had net deferred tax assets of $61.9 million and deferred tax liabilities of $0.3 million, respectively, which are recorded in other long-term liabilities on the consolidated balance sheets. The principal components of the deferred tax assets (liabilities) are summarized as follows:

For the year ended December 31, 2023, the Company recorded a net decrease in valuation allowance of $71.6 million against certain deferred tax assets. The net decrease is primarily a result of current year operations and the change in the assessment of realization of deferred tax assets.

We regularly review our deferred tax assets for realization and establish a valuation allowance if it is more likely than not that some portion or all of a deferred tax asset will not be realized. Historically, we have maintained a full valuation allowance against our deferred tax assets. The Company considers all available positive and negative evidence in determining whether realization of the tax benefit is more likely than not. This evidence includes historical income / loss, projected future income, the expected timing of the reversal of existing temporary differences and the implementation of tax planning strategies. During the fourth quarter of 2023, the Company evaluated all available positive and negative evidence and determined that $61.9 million of the valuation allowance as of December 31, 2023, associated with deferred tax assets should be released because the Company believed that it had become more likely than not that the deferred tax assets would be realized. In the Company's evaluation of the need for and amount of a valuation allowance on its deferred tax assets, the Company placed the most weight on objectively verifiable direct evidence, including its recent and historical operating results and the significant improvement in its operating profitability. The specific positive factors and evidence considered in the realizability of its deferred tax assets included the cumulative pre-tax income that the Company generated over the past three-year period and the expectation of income in future periods. The release of the valuation allowance resulted in the recognition of certain deferred tax assets and a decrease to deferred income tax expense for the year ended December 31, 2023.

As of December 31, 2023, the Company and certain of its corporate subsidiaries had approximately $168.6 million of tax-affected U.S. federal net operating loss carryforwards (“NOLs”), $88.3 million of which the Company expects will expire unused beginning in 2031 due to applicable IRC Section 382 limitations and such NOLs have not been included in the deferred taxes table above. The Company also has tax-affected state NOLs of approximately $24.2 million, $10.4 million of which the Company expects will expire unused due to state law limitations similar to IRC Section 382 and the remaining $13.8 million of which will begin to expire in 2024, and tax-affected non-U.S. NOLs of approximately $1.8 million, which will begin to expire in 2035.

Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement methodology for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.

As of December 31, 2023 and 2022 there wasno liability or expense for the periods then ended recorded for payments of interest and penalties associated with uncertain tax positions or material unrecognized tax positions.

Separate U.S. federal and state income tax returns are filed for Select Inc., SES Holdings and certain consolidated affiliates. The tax years 2019 through 2022 remain open to examination by the major taxing jurisdictions in which the Company is subject to income tax. During 2021, the Louisiana Department of Revenue completed its audits of the corporate income and franchise tax returns of Select Inc. and Select Western, a corporate subsidiary of SES Holdings, for the years ended 2016 through 2018. The audits did not result in a material assessment.

NOTE 16—NONCONTROLLING INTERESTS

The Company’s noncontrolling interests fall into two categories as follows:

During the year ended December 31, 2023, the Company received $6.0 million in cash contributions from a noncontrolling interest for business development. Additionally, the Company divested a formerly consolidated joint venture resulting in a $1.6 million reduction to noncontrolling interest.

During the year ended December 31, 2022, the Company acquired $30.0 million of noncontrolling interest in connection with the Breakwater Acquisition on November 1, 2022, and purchased these noncontrolling interests on December 2, 2022, for $29.3 million. See Note 3—Acquisitions for more detail. Additionally, the Company made a distribution of $0.05 per unit for holders of units of SES Holdings, LLC totaling $0.8 million. See Note 1 –*Business and Basis of Presentation.*Further, the Company contributed to a newly formed water-related services joint venture that added $4.8 million of noncontrolling interest during the year ended December 31, 2022.

During the year ended December 31, 2021, the Company initiated the dissolution of one of its water-related services joint ventures and increased its ownership in another joint venture, which combined, eliminated$0.9 million of noncontrolling interest. For all periods presented, there were no other changes to Select’s ownership interest in joint ventures formed for water-related services. However, during the years ended December 31, 2023, 2022 and 2021, there were changes in Select’s ownership interest in SES Holdings LLC. The effects of the changes in Select’s ownership interest in SES Holdings LLC are as follows:

NOTE 17— INCOME (LOSS) PER SHARE

Income (loss) per share is based on the amount of income (loss) allocated to the stockholders and the weighted-average number of shares outstanding during the period for each class of common stock. Outstanding options to purchase 1,654,952,1,666,872 and 2,074,216 shares of Class A common stock are not included in the calculation of diluted weighted-average shares outstanding for the year ended December 31, 2023, 2022 and 2021 respectively, as their effect is antidilutive.

The following tables present the Company’s calculation of basic and diluted earnings per share for the years ended December 31, 2023, 2022 and 2021 (dollars in thousands, except share and per share amounts):

NOTE 18—SEGMENT INFORMATION

Select Inc. is a leading provider of sustainable water-management and chemical solutions to the oil and gas industry in the U.S. The Company’s services are offered through three reportable segments. Reportable 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 thethree reportable segments. Corporate and other expenses that do not individually meet the criteria for segment reporting are reported separately as Corporate or Other.

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 sourcing, water transfer, flowback and well testing, fluids hauling, water monitoring, water containment and water network automation, primarily serving E&P companies. Additionally, this segment includes the operations of our accommodations and rentals business.

Water Infrastructure— The Water Infrastructure segment consists of the Company’s fixed infrastructure assets, including operations associated with our water distribution pipeline infrastructure, our water recycling solutions, and our produced water gathering systems and saltwater disposal wells, as well as solids disposal facilities, primarily serving E&P companies.
