ORGANIZATION AND OPERATIONS [Abstract]  
Organization and Operations ORGANIZATION AND OPERATIONS
We are an energy services and solutions company with operations on six continents focused on developing environmentally conscious services and solutions that help make people’s lives better. We were incorporated in Delaware in 1981. Our portfolio includes energy services, industrial chemicals and emerging critical minerals opportunities, delivered through our two reporting segments – Completion Fluids & Products and Water & Flowback Services. Unless the context requires otherwise, when we refer to “we,” “us,” and “our,” we are describing TETRA Technologies, Inc. and its consolidated subsidiaries on a consolidated basis.

Our Completion Fluids & Products Segment manufactures and markets clear brine fluids (“CBFs”), additives, and associated products and services to the oil and gas industry for use in well drilling, completion, and workover operations in the United States and in certain countries in Latin America, Europe, Asia, the Middle East, and Africa. The segment also markets liquid and dry calcium chloride products manufactured at its production facilities or purchased from third-party suppliers to a variety of markets outside the energy industry, and produces and markets TETRA PureFlow, an ultra-pure zinc bromide, as well as TETRA PureFlow Plus, an ultra-pure zinc bromide/zinc chloride blend, to several battery technology companies.

Our Water & Flowback Services Segment provides onshore oil and gas operators with comprehensive water management services. The segment also provides frac flowback, production well testing, and other associated services in many of the major oil and gas producing regions in the United States, as well as in oil and gas basins in certain countries in Latin America, Europe, and the Middle East.

Accounting Policies [Abstract]  
Summary of Significant Accounting Policies BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
Principles of Consolidation

Our consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Out-of-Period Corrections

During the three months ended March 31, 2025, we recorded an adjustment to our deferred tax liability related to a correction to our 2024 tax provision. This adjustment increased income tax benefit by $1.2 million and increased net income per share attributable to TETRA stockholders by $0.01 in the consolidated statement of operations for the three months ended March 31, 2025. The Company assessed the impact of this out-of-period adjustment and concluded that it was not material to the financial statements previously issued for any interim or annual period, and the adjustment during the quarter ended March 31, 2025 is not material to the annual financial statements for the year ended December 31, 2025.

During the three months ended June 30, 2024, we discovered that we had not previously remeasured a prepaid tax balance denominated in a foreign currency at current rates, resulting in an overstatement of prepaid expenses and understatement of foreign exchange losses from 2018 through the current period. We corrected this by making an out-of-period adjustment during the three months ended June 30, 2024, which reduced other income, net by $1.4 million and reduced net income per share attributable to TETRA stockholders by $0.01 in the consolidated statement of operations for the year ended December 31, 2024. The Company assessed the impact of this out-of-period adjustment and concluded that it was not material to the financial statements previously issued for any interim or annual period, and the cumulative adjustment during the quarter ended June 30, 2024 is not material to the annual financial statements for 2024. The out-of-period adjustment is included in the Water & Flowback Services Segment results.
Restricted Cash

Restricted cash is classified as a current asset when it is expected to be repaid or settled in the next twelve-month period. Restricted cash as of December 31, 2025 consists of $0.1 million held in escrow in connection with our Arkansas development.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclose contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, and impairments during the reporting period. Actual results could differ from those estimates, and such differences could be material.

Discontinued Operations

In early 2018, we closed a series of related transactions that resulted in the disposition of our former Offshore segment. We may be required to satisfy certain decommissioning liabilities under third-party indemnity agreements and corporate guarantees for which costs may be significant. See Note 9 - “Discontinued Operations” and Note 11 - “Commitments and Contingencies” for additional discussion.

Cash Equivalents

We consider all highly liquid cash investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents include deposits in excess of federally insured amounts.

Financial Instruments

Financial instruments that subject us to concentrations of credit risk consist principally of trade receivables. Our policy is to evaluate, prior to providing goods or services, each customer’s financial condition and to determine the amount of open credit to be extended. We generally require appropriate, additional collateral as security for credit amounts in excess of approved limits. Our customers consist primarily of major, well-established oil and gas producers and independent oil and gas companies, as well as industrial, agricultural, road, and food and beverage purchasers for the chemicals we manufacture. Payment terms are on a short-term basis.

We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. Our risk management activities include the use of foreign currency forward purchase and sale derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected international operations.

We have no outstanding balance under our variable rate revolving credit facilities as of December 31, 2025. Outstanding balances on variable-rate bank credit facilities create market risk exposure related to changes in applicable interest rates.
Allowance for Credit Losses
 
The allowance for credit losses is determined on a specific identification basis when we believe that the collection of specific amounts owed to us is not probable, as well as a percentage of aged receivables based on historic losses. Changes in the allowance are as follows:
 Year Ended December 31,
 202520242023
 (In Thousands)
At beginning of period$626 $614 $538 
Activity in the period:   
Provision for credit losses86 217 285 
Account charge offs, net of recoveries(315)(205)(209)
At end of period$397 $626 $614 

Inventories

Inventories are stated at the lower of cost or net realizable value. Except for work in progress inventory, cost is determined using the weighted average method. The cost of work in progress is determined using the specific identification method.

Property, Plant, and Equipment

Property, plant, and equipment are stated at cost. Expenditures that increase the useful lives of assets are capitalized. The cost of repairs and maintenance is charged to operations as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which are generally as follows:
Buildings
25 years
Machinery and equipment
3 – 10 years
Automobiles and vehicles
4 years
Chemical plants
15 years

Leasehold improvements are depreciated over the shorter of the remaining term of the associated lease or its useful life. Depreciation expense, excluding impairments and other charges, for the years ended December 31, 2025, 2024, and 2023 was $28.5 million, $28.4 million, and $29.2 million, respectively.

Construction in progress as of December 31, 2025 and 2024 consisted primarily of our bromine processing plant in Arkansas, equipment fabrication projects and early production facilities. During the years ended December 31, 2025 and 2024, we capitalized $4.5 million and $1.2 million of interest expense, respectively. We did not capitalize interest during the year ended December 31, 2023.

Intangible Assets other than Goodwill

Customer relationships, trademarks, tradenames, marketing rights and other intangible assets are amortized on a straight-line basis over their estimated useful lives, with remaining useful lives up to 8 years. Amortization of intangible assets was $3.5 million, $4.2 million, and $4.5 million for the years ended December 31, 2025, 2024, and 2023, respectively, and is included in depreciation, amortization and accretion in our consolidated statements of operations. The estimated future annual amortization expense of intangible assets is $3.4 million for 2026, $3.2 million for 2027, $2.7 million for 2028, $2.4 million for 2029, $2.4 million for 2030, and $7.4 million thereafter. See Note 4 - “Intangibles” for additional information.

Intangible assets other than goodwill are tested for recoverability whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. In such an event, we will determine the fair value of the asset using an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we will recognize a loss for the difference between the carrying value and the estimated fair value of the intangible asset.
Leases

As a lessee, unless the lease meets the criteria of short-term and is excluded per our policy election described below, we initially recognize a lease liability and related right-of-use asset on the commencement date. The right-of-use asset represents our right to use an underlying asset and the lease liability represents our obligation to make lease payments to the lessor over the lease term.    

Long-term operating leases are included in operating lease right-of-use assets, operating lease liabilities - current portion, and operating lease liabilities in our consolidated balance sheets. Long-term finance leases are included in machinery and equipment, accrued liabilities and other and other liabilities in our consolidated balance sheets. We determine whether a contract is or contains a lease at inception of the contract. Where we are a lessee in a contract that includes an option to extend or terminate the lease, we include the extension period or exclude the period covered by the termination option in our lease term in determining the right-of-use asset and lease liability, if it is reasonably certain that we would exercise the option.

As an accounting policy election, we do not include short-term leases on our balance sheets. Short-term leases include leases with a term of 12 months or less, inclusive of renewal options we are reasonably certain to exercise. The lease payments for short-term leases are included as operating lease costs on a straight-line basis over the lease term in cost of revenues or general and administrative expense based on the use of the underlying asset. We recognize lease costs for variable lease payments not included in the determination of a lease liability in the period in which an obligation is incurred.

Our operating and finance leases are recognized at the present value of lease payments over the lease term. When the implicit discount rate is not readily determinable, we use our incremental borrowing rate to calculate the discount rate used to determine the present value of lease payments. Consistent with other long-lived assets or asset groups that are held and used, we test for impairment of our right-of-use assets when impairment indicators are present.

Impairments of Inventory and Long-Lived Assets

Impairments of inventory and long-lived assets, including identified intangible assets, are determined periodically when indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is based on our judgments as to the future undiscounted operating cash flows to be generated from these assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related asset, an impairment is recognized for the excess of the carrying value over its fair value. Assets held for disposal are recorded at the lower of carrying value or estimated fair value less estimated selling costs. See Note 5 - “Impairments and Other Charges” for additional discussion of recorded impairments.

Revenue Recognition

Performance Obligations. Revenue is generally recognized when we transfer control of our products or services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services to our customers. We receive cash equal to the invoice price for most sales of product and services and payment terms typically range from 30 to 60 days from the date we invoice our customer. Since the period between when we deliver products or services and when the customer pays for such products or services is not expected to exceed one year, we have elected not to calculate or disclose a financing component for our customer contracts.

    Depending on the terms of the arrangement, we may also defer the recognition of revenue for a portion of the consideration received because we have to satisfy a future performance obligation.

    For any arrangements with multiple performance obligations, we use management’s estimated selling price to determine the stand-alone selling price for separate performance obligations. For revenue associated with mobilization of service equipment as part of a service contract arrangement, such revenue, if significant, is deferred and amortized over the estimated service period.
    Product Sales. Product sales revenues are recognized at a point in time when we transfer control of our product offerings to our customers, generally when we ship products from our facility to our customer. The product sales for our Completion Fluids & Products Segment consist primarily of CBFs, additives, and associated manufactured products. Certain customers have bill-and-hold arrangements. Revenue for bill-and-hold arrangements is recognized when control transfers to the customer, even though the customer may not have physical possession of the product. Control transfers when there is a substantive reason for the arrangement, the product is identified as belonging to the customer, is ready for physical transfer, and cannot be directed for use by anyone but the customer. Product sales for our Water & Flowback Services Segment are typically attributed to specific performance obligations within certain production testing service arrangements.

    Services. Service revenues represent revenue recognized over time, as our customer arrangements typically provide agreed upon day rates and we recognize service revenue based upon the number of days services have been performed. Service revenue recognized over time is associated with a majority of our Water & Flowback Services Segment arrangements, and a small portion of Completion Fluids & Products Segment revenue that is associated with completion fluid service arrangements. Our customer contracts are generally for terms of one year or less. The majority of the service arrangements in the Water & Flowback Services Segment are for a period of 90 days or less.

    Sales taxes, value added taxes, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We have elected to recognize the cost for freight and shipping costs as part of cost of product sales when control over our products (i.e., delivery) has transferred to the customer.

    Use of Estimates. In recognizing revenue for variable consideration arrangements, the amount of variable consideration recognized is limited so that it is probable that significant amounts of revenues will not be reversed in future periods when the uncertainty is resolved. For products returned by the customer, we estimate the expected returns based on an analysis of historical experience. For volume discounts earned by the customer, we estimate the discount (if any) based on our estimate of the total expected volume of products sold or services to be provided to the customer during the discount period. In certain contracts for the sale of CBFs, we may agree to issue credits for the repurchase of reclaimable used fluids from certain customers at an agreed price that is based on the condition of the fluids and, in some cases, the volume of fluids sold.

    Contract Assets and Liabilities. We consider contract assets to be trade accounts receivable when we have an unconditional right to consideration and only the passage of time is required before payment is due. In certain instances, particularly those requiring customer specific documentation prior to invoicing, our invoicing of the customer is delayed until certain documentation requirements are met. In those cases, we recognize a contract asset rather than a billed trade accounts receivable until we are able to invoice the customer. Contract assets, along with billed trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets.

    We classify contract liabilities as unearned income in our consolidated balance sheets. Unearned income includes amounts in which the Company was contractually allowed to invoice prior to satisfying the associated performance obligations.

Operating Costs

Cost of product sales includes direct and indirect costs of manufacturing and producing our products, including raw materials, fuel, utilities, labor, overhead, repairs and maintenance, materials, services, transportation, warehousing, equipment rentals, insurance, and certain taxes. Cost of services includes operating expenses we incur in delivering our services, including labor, equipment rental, fuel, repair and maintenance, transportation, overhead, insurance, and certain taxes. We include in product sales revenues the reimbursements we receive from customers for shipping and handling costs. Shipping and handling costs are included in cost of product sales. Amounts we incur for “out-of-pocket” expenses in the delivery of our services are recorded as cost of services. Reimbursements for “out-of-pocket” expenses we incur in the delivery of our services are recorded as service revenues. Depreciation, amortization, and accretion includes depreciation expense for all of our facilities, equipment and vehicles, amortization expense on our intangible assets, and accretion expense related to our decommissioning and other asset retirement obligations.

We include in general and administrative expense all costs not identifiable to our specific product or service operations, including segment and general corporate overhead, professional services, corporate office costs, sales and marketing expenses, insurance, and certain taxes.
Collaborative Arrangement

We are pursuing low-carbon energy initiatives that leverage our fluids core chemistry competencies and our significant mineral resources, including our brine leases in Southwest Arkansas. In June 2023, we entered into a memorandum of understanding with Saltwerx, LLC (“Saltwerx”), an indirect wholly owned subsidiary of ExxonMobil Corporation, relating to a newly-proposed brine unit in the Smackover Formation in Southwest Arkansas and potential bromine and lithium production from brine produced from the unit. The memorandum of understanding includes an allocation of certain costs for the drilling of a brine production test well and other development operations, including front-end engineering and design studies for bromine and lithium production facilities.

During the years ended December 31, 2025 and 2024, we capitalized approximately $45.2 million and $22.4 million, respectively, of costs, net of reimbursements from our partner, associated with the development of our properties in Arkansas, excluding capitalized interest, which are included in capital expenditures for our Completion Fluids & Products Segment. During the year ended December 31, 2023, we incurred $12.1 million of exploration and pre-development costs and recorded $9.3 million in reimbursements associated with this arrangement. This income is included in other (income) expense, net in our consolidated statements of operations.

Loss Contingencies

We and certain of our subsidiaries are involved, in the normal course of business, in lawsuits, claims and other legal proceedings and audits. We accrue reserves for these matters when we believe it is probable that a liability has been incurred and the liability can be reasonably estimated. In addition, we disclose exposure to certain losses in excess of the amount recorded on the balance sheet for these matters if it is reasonably possible that an additional material loss may be incurred. We review such loss contingencies on an ongoing basis. Loss contingencies are based on judgments made by management with respect to the likely outcome of these matters and are adjusted as appropriate. Management’s judgments could change based on new information, changes in, or interpretations of, laws or regulations, changes in management’s plans or intentions, opinions regarding the outcome of legal proceedings or other factors. See Note 11 - Commitments and Contingencies - Litigation and Contingencies of Discontinued Operations for additional information.

Equity-Based Compensation

    We have various equity incentive compensation plans which provide for the granting of restricted common stock, options for the purchase of our common stock, and other performance-based, equity-based compensation awards to our executive officers, key employees, nonexecutive officers, and directors. Upon the vesting of restricted stock awards or exercise of employee stock options, we issue new shares of common stock. Forfeitures of equity-based compensation awards are recognized as they occur. Total equity-based compensation expense, net of taxes, for the years ended December 31, 2025, 2024, and 2023, was $6.8 million, $6.3 million, and $10.4 million, respectively. For further discussion of equity-based compensation, see Note 13 – “Equity-Based Compensation and Other”.

Mineral Resources Arrangements

    We are party to agreements in which Standard Lithium Ltd. (“Standard Lithium”) has the right to explore, produce and extract lithium in our Arkansas leases as well as additional potential resources in the Mojave region of California. The Company received cash and stock of Standard Lithium (NYSE:SLI) under the terms of the arrangements. The cash and stock component of consideration received is initially recorded as unearned income based on the quoted market price at the time the stock is received, then recognized in income over the contract term. Deferred income balances were $1.0 million and $1.0 million as of December 31, 2025 and 2024, respectively, associated with the consideration received from Standard Lithium and are included in accrued liabilities and other in our consolidated balance sheets. During the years ended December 31, 2025, 2024, and 2023, income from this arrangement was $1.0 million, $1.6 million, and $3.0 million, respectively, from the value of cash and stock received, and $2.4 million, $(0.4) million and $(1.0) million, respectively, for unrealized gains (losses) on changes in the value of Standard Lithium stock held. See Note 14 - “Fair Value Measurements” for further discussion.
Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis amounts. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates is recognized as income or expense in the period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. A portion of the carrying value of certain deferred tax assets are subject to a valuation allowance. See Note 15 – “Income Taxes” for further discussion.

    The global intangible low-taxed income (“GILTI’) provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. We elected to account for GILTI as a period cost in the year the tax is incurred.

We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than fifty percent likely to be realized upon ultimate settlement with the related tax authority. We recognize interest expense and penalties on uncertain tax positions and income tax deficiencies as a component of income tax (benefit) expense.

Tax Benefits Preservation Plan

On February 28, 2023, the Board of Directors adopted a Tax Benefits Preservation Plan (the “Tax Plan”) designed to preserve the availability of the Company’s existing net operating loss carryforwards (“NOLs”) and other tax attributes (collectively, the “Tax Attributes”). The Board of Directors approved Amendment No. 1 (the “Amendment”) to the Tax Plan on February 19, 2026 and the Company entered into the Amendment on February 25, 2026. The Amendment extends the expiration date of the Tax Plan from February 28, 2026 to February 28, 2029 (subject to other earlier termination events).The Tax Attributes may be utilized in certain circumstances to reduce our future income tax obligations. However, our ability to utilize the Tax Attributes would be substantially limited if an “ownership change” under Section 382 (“Section 382”) of the Internal Revenue Code of 1986, as amended (the “Code”) were to occur. In general, an ownership change under Section 382 occurs if one or more stockholders (or group of stockholders) who are each deemed to own at least 5% of the corporation’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a testing period (generally, a rolling three-year period). The Tax Plan contributes to the preservation of the Company’s Tax Attributes by reducing the risk that an ownership change under Section 382 occurs.

In adopting the Tax Plan, the Board of Directors declared a dividend of one Series A Junior Participating Preferred Stock purchase right (the “Rights”) for each outstanding share of Common Stock pursuant to the terms of the Tax Plan. Initially, each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share, of the Company (the “Preferred Stock”) at a price of $20.00 per one one-thousandth of a share of Preferred Stock (the “Purchase Price”), subject to adjustment. The Rights will cause substantial dilution to a person or group that acquires 4.99% or more of the Common Stock (or to a person or group that already owns 4.99% or more of the Company’s Common Stock if such person or group acquires additional shares representing 2% of the Company’s then outstanding shares of Common Stock) without prior approval from the Board of Directors.

The Rights will expire at the earliest of: (i) the close of business on February 28, 2029 (the “Final Expiration Date”); (ii) the time at which the Rights are redeemed pursuant to the Tax Plan, (iii) the time at which the Rights are exchanged pursuant to the Tax Plan; (iv) the closing of any merger or other acquisition transaction involving the Company pursuant to an agreement as described in the penultimate paragraph of Section 1.3 of the Tax Plan; (v) the close of business on the effective date of the repeal of Section 382 of the Code if the Board determines that the
Tax Plan is no longer necessary or desirable for the preservation of the Tax Attributes; or (vi) the close of business on the first day of a taxable year of the Company following a Board determination that no Tax Attributes may be carried forward or otherwise utilized.

The Tax Plan adopted by the Board of Directors is similar to plans adopted by other publicly held companies with significant NOLs or other substantial Tax Attributes and is not designed to prevent any action that the Board of Directors determines to be in the best interest of the Company and its stockholders. At the Company’s 2023 annual meeting of stockholders held on May 24, 2023, the Company’s stockholders ratified the adoption of the Tax Plan. The Company intends to submit the Amendment to its stockholders for ratification at the 2026 annual meeting of stockholders.

The Rights are in all respects subject to and governed by the provisions of the Tax Plan. The foregoing summary provides only a general description of the Tax Plan and does not purport to be complete. The Tax Plan, which specifies the terms of the Rights and includes as an exhibit the Form of Right Certificate. The foregoing summary should be read together with the entire Tax Plan and the Amendment and is qualified in its entirety by reference to the Tax Plan and the Amendment.

In connection with the Amendment, the Company filed a Certificate of Designation of Series A Junior Participating Preferred Stock of the Company with the Secretary of State of the State of Delaware, which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

Noncontrolling Interests

Noncontrolling interests represent third-party ownership in the net assets of the Company’s consolidated subsidiaries and are presented as a component of equity. The Company’s noncontrolling interests as of December 31, 2025 and 2024 consists primarily of the outside ownership of subsidiaries in Africa.

Accumulated Other Comprehensive Income (Loss)

Certain of our international operations maintain their accounting records in the local currencies that are their functional currencies. For these operations, the functional currency financial statements are converted to United States dollar equivalents, with the effect of the foreign currency translation adjustment reflected as a component of accumulated other comprehensive income (loss). Accumulated other comprehensive income (loss) is included in equity in the accompanying consolidated balance sheets and consists of the cumulative currency translation adjustments associated with such international operations.

In addition, the change in the fair value of the convertible note, excluding the embedded option, is included in other comprehensive income (loss) in our consolidated statements of comprehensive income. The portion of our accumulated other comprehensive income (loss) attributable to the convertible note is subject to reclassifications to net income if or when we settle the convertible note. See Note 8 – “Investments” for further discussion of the convertible note.

Income (Loss) per Common Share

The calculation of basic and diluted earnings per share excludes losses attributable to noncontrolling interests. The calculation of basic earnings per share excludes any dilutive effects of equity awards. The calculation of diluted earnings per share includes the effect of equity awards, if dilutive, which is computed using the treasury stock method during the periods such equity awards were outstanding. See Note 16 – “Net Income Per Share” for further discussion of shares outstanding.

Foreign Currency Translation

We have designated the Euro, the British pound, the Canadian dollar, and the Brazilian real as the functional currencies for our operations in Finland and Sweden, the United Kingdom, Canada, and Brazil, respectively. The United States dollar is the designated functional currency for all of our other significant non-U.S. operations. The cumulative translation effects of translating the applicable accounts from the functional currencies into the U.S. dollar at current exchange rates are included as a separate component of equity. Foreign currency exchange losses are included in other (income) expense, net, and totaled $8.3 million, $3.8 million, and $3.5 million for the years ended December 31, 2025, 2024, and 2023, respectively. Foreign currency exchange losses during
the year ended December 31, 2025 include recognition of a $9.5 million cumulative foreign currency translation adjustment loss, which was reclassified from accumulated other comprehensive loss due to the dissolution of our former subsidiary in Canada during 2025.

Fair Value Measurements

We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized on a recurring basis in the determination of the carrying values of certain investments. See Note 8 – “Investments” and Note 14 - “Fair Value Measurements” for further discussion.

Fair value measurements are also utilized on a nonrecurring basis in certain circumstances, such as in the allocation of purchase consideration for acquisition transactions to the assets and liabilities acquired, including intangible assets and goodwill (a Level 3 fair value measurement), the initial recording of our asset retirement obligations, and for the impairment of long-lived assets, including goodwill (a Level 3 fair value measurement).

New Accounting Pronouncements

Recently Adopted Accounting Pronouncement

Effective January 1, 2025, we adopted ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, on a prospective basis. This standard requires enhanced disclosures of income taxes, including disaggregated effective tax rate reconciliation by specific categories in both dollars and percentages. income taxes paid disaggregated by jurisdiction, and qualitative explanations for significant reconciling items. The adoption of ASU 2023-09 did not impact our recognition or measurement of income taxes but resulted in expanded disclosures as reflected in Note 2 - “Summary of Significant Accounting Policies” and Note 15 - “Income Taxes.”

Standards not yet adopted

In December 2025, the FASB issued Accounting Standards Update (“ASU”) 2025-12, Codification Improvements, as part of its ongoing project to clarify and correct various areas of U.S. GAAP. The amendments span multiple Topics and include clarifications related to diluted earnings per share, lease receivable disclosures, and transfers of receivables, among others. These changes are not expected to significantly affect current accounting practices. Effective dates vary depending on the underlying Topic. We do not expect ASU 2025-12 to have a material impact on our consolidated financial statements as the amendments clarify existing guidance, but we will continue to monitor its applicability

In December 2025, the FASB also issued ASU 2025-11, “Narrow-Scope Improvements” (“ASU 2025-11”), which clarifies required interim disclosures. ASU 2025-11 addresses the form and content of interim financial statements and footnotes prepared in accordance with GAAP, lists the interim disclosures required by all other
Codification topics, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and may be applied prospectively or retrospectively. The adoption of the standard will not have an impact on our consolidated statements of operations or balance sheets as the standard only impacts interim disclosures.

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets” (“ASU 2025-05”), which provides entities with optional relief when estimating expected credit losses for current accounts receivable arising from transactions accounted for under Accounting Standards Codification 606. The amendments permit entities to apply a practical expedient that assumes current economic conditions as of the balance sheet date remain unchanged for the remaining life of the asset. The Company expects to adopt the practical expedient effective January 1, 2026 and is assessing the impact of ASU 2025-05 to its consolidated financial statements upon adoption.

In November 2024, the FASB issued ASU 2024-03, “Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40)” ("ASU 2024-03"). ASU 2024-03 requires additional disclosures about certain expenses included in the income statement, including purchases of inventory, employee compensation, intangible asset amortization and depreciation. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027 with early adoption permitted. The Company is currently assessing the impact of ASU 2024-03 and does not expect a significant impact to its consolidated financial statements upon adoption as the standard expands disclosures.

Discontinued Operations and Disposal Groups [Abstract]  
Discontinued Operations DISCONTINUED OPERATIONS
In early 2018, we closed the Maritech APA and Maritech MIPA with Orinoco that together provided for the purchase by Orinoco of all of Maritech’s remaining oil and gas properties and related assets and all outstanding membership interests of Maritech. Under the Maritech APA, Orinoco assumed responsibility for all of Maritech’s decommissioning liabilities related to the leases sold to Orinoco and, under the Maritech MIPA, Orinoco assumed all other liabilities of Maritech, including the decommissioning liabilities associated with Maritech’s interests in oil and gas properties previously sold by Maritech and select infrastructure still operated by Maritech, subject to certain limited exceptions unrelated to the decommissioning liabilities. To the extent that Maritech or Orinoco fails to satisfy decommissioning liabilities associated with any of the Orinoco Lease Liabilities or the Legacy Liabilities, we may be required to satisfy such liabilities under third party indemnity agreements and corporate guarantees that we previously provided to BSEE and other parties, respectively, for which costs may be significant. Pursuant to a Bonding Agreement entered into as part of these Orinoco transactions (the “Bonding Agreement”), Orinoco provided non-revocable performance bonds from a surety company in an aggregate amount of $46.8 million to cover the performance by Orinoco and Maritech of certain specific asset retirement obligations of Maritech (the “Initial Bonds”) and agreed to replace the Initial Bonds with other non-revocable performance bonds in the aggregate sum of $47.0 million (collectively, the “Replacement Bonds”). In the event Orinoco does not provide the Replacement Bonds, Orinoco is required to make certain cash escrow payments to us. To date, no cash escrow payments have been made. On August 16, 2024, we issued a letter to Orinoco and the bond company demanding realignment of the existing bonds and/or issuance of Replacement Bonds pursuant to the terms of the Bonding Agreement to better align bond coverage with the more likely liability risks. To date, no written response has been received.

In addition, Maritech and certain other interest owners have received decommissioning orders from BSEE and could receive additional decommissioning orders in the future. Such decommissioning orders received by Maritech and other interest owners relate to asset retirement obligations for certain properties in the Gulf of
America. From time to time, we also receive demand notices from third parties related to certain corporate guarantees or other arrangements covering such decommissioning liabilities. While the ultimate outcome of such matters cannot be predicted at this time, if Maritech or other interest owners default, BSEE or third parties may seek to enforce certain corporate guarantees or third party indemnity agreements against us for a portion of such decommissioning obligations, which may be significant.

With respect to certain properties in the Gulf of America, we have been advised that the cost of the decommissioning work to plug and abandon certain wells is projected to be significantly higher than the approximately $10.7 million bond supporting the liability, which was put in place by Maritech and other interest owners based on earlier cost estimates. We have also been advised more recently that Maritech’s prior working interest with respect those plugging and abandonment (“P&A”) costs are expected to exceed its share of the bond. In September 2024, P&A operations commenced pursuant to a cost sharing agreement among certain parties for decommissioning certain properties in the Gulf of America. While Maritech is not a party to this cost sharing agreement, a predecessor of Maritech has advised us that it expects to seek reimbursement from us for the portion of decommissioning costs it has contractually agreed to pay pursuant to the terms of the cost sharing agreement. While the ultimate outcome of this matter cannot be predicted, we could potentially be liable for an estimated amount in the range of $11.3 million to $27.0 million, before Maritech’s proportionate share of the bond proceeds (approximately $3.9 million), depending on the outcome of negotiations and whether other partners or property owners in the chain of title fulfill their respective obligations under their agreements. Additionally, we understand that in connection with the P&A operations being performed, Maritech and the other named obligees have made a demand on the related bond. We have made efforts to protect Maritech’s proportionate share of the bond proceeds, including demanding that the surety segregate or ensure that Maritech’s share is applied solely to satisfy its proportionate share of the decommissioning costs. We accrued liabilities of $7.4 million and $5.8 million related to this obligation as of December 31, 2025 and December 31, 2024, respectively.
A summary of financial information related to our discontinued operations is as follows:

Revenue from Contract with Customer [Abstract]  
Revenue REVENUE
    Our contract asset balances, primarily associated with customer documentation requirements, were $24.4 million, $30.4 million, and $30.6 million as of December 31, 2025, 2024, and 2023, respectively. Contract assets, along with billed trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets.

Unearned income includes amounts in which the Company was contractually allowed to invoice prior to satisfying the associated performance obligations. Unearned income balances were $5.9 million, $0.4 million, and $3.1 million as of December 31, 2025, 2024, and 2023, respectively, and vary based on the timing of invoicing and performance obligations being met. Unearned income is included in accrued liabilities and other in our consolidated balance sheets. During the years ended December 31, 2025, 2024, and 2023, we recognized approximately $0.3 million, $2.8 million, and $1.8 million, respectively, of revenue deferred in unearned income as of the beginning of each period. This amount is included in products sales and services revenues in our consolidated statements of operations. During the years ended December 31, 2025, 2024, and 2023, contract costs were not significant.

We disaggregate revenue from contracts with customers into Product Sales and Services within each segment, as noted in our two reportable segments in Note 17 - “Industry Segments and Geographic Information”. In addition, we disaggregate revenue from contracts with customers by geography based on the following table below:

During 2025, we recorded a $3.6 million impairment of our former corporate office lease related to the relocation of our corporate headquarters and we recorded $0.6 million impairments of certain long-lived assets and right of use assets, within our Water & Flowback Services Segment. The fair values of right of use assets were estimated based on the discounted cash flows of our lease payments (a Level 3 fair value measurement) in accordance with the fair value hierarchy. The fair values of other long-lived assets was based on the estimated market values of similar equipment (a Level 3 fair value measurement).

During 2024, we recorded a $0.1 million impairment of our corporate office lease. During 2023, we recorded a $2.1 million impairment of a facility lease in Scotland within our Completion Fluids & Products Segment and we recorded a $0.8 million impairment of our corporate office lease. The fair values were estimated based on the discounted cash flows from our lease and sublease agreements (a Level 3 fair value measurement) in accordance with the fair value hierarchy.

In January 2025, we sold our Kodiak shares for proceeds of $19.0 million, net of transaction and broker fees.

The Company received stock of Standard Lithium under the terms of arrangements whereby Standard Lithium has the right to explore for, produce and extract lithium in our Arkansas leases and other additional potential resources in the Mojave region of California. The stock component of consideration received from Standard Lithium was initially recorded as unearned income based on the quoted market price at the time the stock was received, then recognized in income over the contract term. Changes in the value of stock are recorded in other (income) expense, net in our consolidated statements of operations.

Leases LEASES
Operating and Finance Leases

We have operating leases for some of our transportation equipment, office space, warehouse space, operating locations, and machinery and equipment. We have finance leases for certain facility storage tanks and equipment rentals. Our leases have remaining lease terms ranging from 1 to 13 years. Some of our leases have options to extend for various periods, while some have termination options with prior notice of generally 30 days or six months. The office space, warehouse space, operating location leases, and machinery and equipment leases generally require us to pay all maintenance and insurance costs.

In August 2025, we entered into an operating lease agreement for a new corporate headquarters facility in Spring, Texas. We recognized a right-of-use asset and corresponding long-term lease liability of approximately $10.5 million. The term is thirteen years and includes fixed monthly base rent payments totaling approximately $1.8 million annually beginning in early 2028 and continuing through the lease term, including scheduled annual escalations. We also expect to incur additional costs related to facility management and operations, which will be expensed as incurred as variable lease costs.

Our former corporate operating lease expires in December 2027, a portion of which is subleased. Upon abandonment of our former corporate office in late 2025 that is not subleased, we recorded a non-cash charge of approximately $9.5 million, including a $3.6 million impairment of the right of use asset and accrual of approximately $5.9 million of estimated facility management and operational costs expected to be incurred through the lease expiration in December 2027, which is included in other (income) expense, net in our consolidated statements of operations, and will be offset by concessions from the new lease during 2026 and 2027.

Components of lease expense, included in either cost of revenues or general and administrative expense based on the use of the underlying asset, are as follows (inclusive of lease expense for leases not included on our consolidated balance sheet based on our accounting policy election to exclude leases with a term of 12 months or less):

Term Credit Agreement

    On January 12, 2024, the Company entered into a definitive agreement for a $265.0 million credit facility, consisting of a $190.0 million funded term loan and a $75.0 million delayed-draw term loan (collectively the “Term Credit Agreement”) that refinanced the Company’s prior credit facility outstanding as of December 31, 2023 and provided capital to advance the Company’s Arkansas project. The $75.0 million delayed-draw provision of the Term Credit Agreement expired on January 12, 2026. Pricing on the Term Credit Agreement is the secured overnight financing rate (“SOFR”) plus 5.75%. The Company was required to pay a commitment fee on the unutilized commitments with respect to the delayed-draw term loan at the rate of 1.50% per annum. The interest rate per annum on borrowings under the Term Credit Agreement is 9.57% as of December 31, 2025 and the maturity date of the Term Credit Agreement is January 1, 2030. The Company used the net proceeds to repay in full the balance of its prior credit facility, with approximately $15.2 million of additional cash, net of discounts and transaction expenses. In connection with the Term Credit Agreement, we incurred approximately $5.7 million of fees which were deferred and will be amortized over the term of the Term Credit Agreement. As a result of termination of the prior credit facility, a loss of $5.5 million was recognized during the three-month period ended March 31, 2024 primarily for unamortized deferred financing costs.

The Term Credit Agreement contains certain affirmative and negative covenants, including covenants that restrict the ability of the Company and certain of its subsidiaries to take certain actions including, among other things and subject to certain significant exceptions, the incurrence of debt, the granting of liens, engaging in mergers and other fundamental changes, the making of investments, entering into transactions with affiliates, the payment of dividends and other restricted payments, the prepayment of other indebtedness and the sale of assets. The Term Credit Agreement also requires the Company to maintain a Leverage Ratio (as defined in the new term loan credit agreement) of not more than 4.0 to 1.0 as of the end of each fiscal quarter and Liquidity (as defined in the Term Credit Agreement) of not less than $50.0 million at all times.

All obligations under the Term Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a security interest on substantially all of the property of the Company and its domestic subsidiaries, subject to the lien priorities set forth in the intercreditor agreement with the agent under our ABL Credit Agreement.
Our Term Credit Agreement requires us to offer to prepay a percentage of Excess Cash Flow (as defined in the Term Credit Agreement) within five business days of filing our Annual Report. We are not required to offer to prepay any of our Term Credit Agreement based on our Leverage Ratio as of December 31, 2025.

The Term Credit Agreement includes customary events of default including non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations or warranties, cross-default to other material indebtedness, bankruptcy and insolvency events, invalidity or impairment of security interests or invalidity of loan documents, certain ERISA events, unsatisfied or unstayed judgments and change of control.

ABL Credit Agreement

On May 13, 2024, we entered into an amendment (the “ABL Amendment”) to the Asset-Based Lending agreement dated as of September 10, 2018 (as amended, the “ABL Credit Agreement”). In connection with the ABL Amendment, Bank of America, N.A. became successor administrative agent to JPMorgan Chase Bank, N.A. Furthermore, approximately $0.9 million of fees were incurred in connection with the ABL Amendment, which were deferred and will be amortized over the term of the ABL Credit Agreement.

As of December 31, 2025, our ABL Credit Agreement provides, with certain restrictions, for a senior secured revolving credit facility of up to $100.0 million with a $25.0 million accordion. The credit facility is subject to a borrowing base determined monthly by reference to the value of inventory and accounts receivable, and includes a sublimit of $20.0 million for letters of credit, and a swingline loan sublimit of $11.5 million. The ABL Credit Agreement matures on May 13, 2029.

As of December 31, 2025, we had no borrowings outstanding and $0.2 million letters of credit or guarantees under our ABL Credit Agreement. Deferred financing costs of $0.9 million and $1.0 million as of December 31, 2025 and 2024, respectively, were classified as other long-term assets on the accompanying consolidated balance sheet as there was no outstanding balance on our ABL Credit Agreement. Subject to compliance with the covenants, borrowing base, and other provisions of the ABL Credit Agreement that may limit borrowings, we had availability of $67.7 million under this agreement.

Borrowings under the ABL Credit Agreement bear interest at a rate per annum equal to, at the option of TETRA, either (i) the standard overnight financing rate plus 0.10%, (ii) a base rate plus a margin based on a fixed charge coverage ratio, or (iii) the Daily Simple Risk Free Rate plus 0.10%. The base rate is determined by reference to the highest of (a) the prime rate of interest as announced from time to time by Bank of America, N.A. (b) the Federal Funds Effective Rate (as defined in the ABL Credit Agreement) plus 0.5% per annum and (c) the standard overnight financing rate (adjusted to reflect any required bank reserves) for a one-month period on such day plus 1.0% per annum, provided that the base rate shall not be less than 1.0%. Borrowings outstanding have an applicable margin ranging from 2.00% to 2.50% per annum for SOFR-based loans and 1.00% to 1.50% per annum for base-rate loans, based upon the applicable fixed charge coverage ratio. In addition to paying interest on the outstanding principal under the ABL Credit Agreement, TETRA is required to pay a commitment fee in respect of the unutilized commitments at an applicable rate of 0.375% per annum. TETRA is also required to pay a customary letter of credit fee equal to the applicable margin on loans and fronting fees.

     All obligations under the ABL Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a security interest for the benefit of the ABL Lenders on substantially all of the personal property of TETRA and certain subsidiaries of TETRA, the equity interests in certain domestic subsidiaries, and a maximum of 65% of the equity interests in certain foreign subsidiaries.

Swedish Credit Facility

The Company has a revolving credit facility for seasonal working capital needs of subsidiaries in Sweden and Finland (“Swedish Credit Facility”). As of December 31, 2025, we had no balance outstanding and availability of approximately $5.4 million under the Swedish Credit Facility. During each year, all outstanding loans under the Swedish Credit Facility must be repaid for at least 30 consecutive days. Borrowings bear interest at a rate of 2.95% per annum. The Swedish Credit Facility expired on December 31, 2025 and has been renewed by the Company through December 31, 2026. Any balance outstanding under the Swedish Credit Facility is included in accrued liabilities and other in our consolidated balance sheet.
Finland Credit Agreement

The Company has an agreement guaranteed by certain accounts receivable and inventory in Finland (“Finland Credit Agreement”). As of December 31, 2025, we had $1.6 million of letters of credit outstanding against the Finland Credit Agreement. The Finland Credit Agreement has been renewed by the Company through December 31, 2026.

Covenants

Our credit agreements contain certain affirmative and negative covenants, including covenants that restrict the ability to pay dividends or other restricted payments. As of December 31, 2025, we were in compliance with all covenants under the credit agreements.

We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or other proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse impact on our financial condition, results of operations, or liquidity.

We have a Bromine Requirements Sales Agreement (“Sales Agreement”) to purchase a certain volume of elemental bromine from LANXESS Corporation (formerly Chemtura Corporation) (“LANXESS”), included in Product Purchase Obligations below. LANXESS notified us of a proposed non-ordinary course increase to the price of bromine. After lengthy discussions, we and LANXESS were unable to reach an agreement regarding the validity of the proposed price increase; therefore, we filed for arbitration in May 2022 seeking declaratory relief, among other relief, declaring that the proposed price increase is invalid. In September 2022, LANXESS filed a counterclaim with the American Arbitration Association seeking declaratory relief, among other relief. On May 25, 2023, TETRA entered into the Third Amendment to Bromine Requirements Sales Agreement (the “Amendment”) with LANXESS. The Amendment has an effective date of April 1, 2023 and was entered into in connection with the entry into a settlement agreement in the Company’s arbitration with LANXESS. The Amendment provides for, among other things, revised volume requirements, pricing and related terms. On June 14, 2023, in light of the settlement agreement, and in response to the parties’ stipulated motion to dismiss, the arbitration panel issued an Order of Dismissal, which dismissed all claims in the arbitration with prejudice.

In the normal course of our Completion Fluids & Products Segment operations, we enter into supply agreements with certain manufacturers of various raw materials and finished products. Some of these agreements have terms and conditions that specify a minimum or maximum level of purchases over the term of the agreement. Other agreements require us to purchase the entire output of the raw material or finished product produced by the manufacturer. Our purchase obligations under these agreements apply only with regard to raw materials and finished products that meet specifications set forth in the agreements. We recognize a liability for the purchase of such products at the time we receive them. As of December 31, 2025, the aggregate amount of the fixed and determinable portion of the purchase obligation pursuant to our Completion Fluids & Products Segment’s supply agreements was approximately $95.5 million, including $57.4 million for the year ending December 31, 2026, $28.5 million for the year ending December 31, 2027, and $9.6 million for the year ending December 31, 2028. Amounts purchased under these agreements for each of the years ended December 31, 2025, 2024, and 2023, was $66.4 million, $56.3 million, and $46.9 million, respectively. As of December 31, 2025, we also have commitments of $15.3 million related to long-lead power infrastructure for our Completion Fluids & Products Segment’s bromine plant in Arkansas, including $1.8 million expected to be paid in the first quarter of 2026 and included in accrued liabilities and other in our consolidated balance sheets, and $13.5 million due over five years beginning after electric service is available.
Contingencies of Discontinued Operations

In early 2018, we closed the Maritech Asset Purchase and Sale Agreement (“Maritech APA") and Maritech Membership Interest Purchase Agreement (“Maritech MIPA”) with Orinoco Natural Resources, LLC (“Orinoco”) that together provided for the purchase by Orinoco of all of Maritech’s remaining oil and gas properties and related assets and all outstanding membership interests of Maritech. Under the Maritech APA, Orinoco assumed responsibility for all of Maritech’s decommissioning liabilities related to the leases sold to Orinoco (the “Orinoco Lease Liabilities”) and, under the Maritech MIPA, Orinoco assumed all other liabilities of Maritech, including the decommissioning liabilities associated with Maritech’s interests in oil and gas properties previously sold by Maritech and select infrastructure still operated by Maritech (the “Legacy Liabilities”), subject to certain limited exceptions unrelated to the decommissioning liabilities. To the extent that Maritech or Orinoco fails to satisfy decommissioning liabilities associated with any of the Orinoco Lease Liabilities or the Legacy Liabilities, we may be required to satisfy such liabilities under third party indemnity agreements and corporate guarantees that we previously provided to the U.S. Department of the Interior (“BSEE”) and other parties, respectively, for which costs may be significant. Pursuant to a Bonding Agreement entered into as part of these Orinoco transactions (the “Bonding Agreement”), Orinoco provided non-revocable performance bonds from a surety company in an aggregate amount of $46.8 million to cover the performance by Orinoco and Maritech of certain specific asset retirement obligations of Maritech (the “Initial Bonds”) and agreed to replace the Initial Bonds with other non-revocable performance bonds in the aggregate sum of $47.0 million (collectively, the “Replacement Bonds”). In the event Orinoco does not provide the Replacement Bonds, Orinoco is required to make certain cash escrow payments to us. To date, no cash escrow payments have been made. On August 16, 2024, we issued a letter to Orinoco and the bond company demanding realignment of the existing bonds and/or issuance of Replacement Bonds pursuant to the terms of the Bonding Agreement to better align bond coverage with the more likely liability risks. To date, no written response has been received.

The payment obligations of Orinoco under the Bonding Agreement were guaranteed by Thomas M. Clarke and Ana M. Clarke pursuant to a separate guaranty agreement (the “Clarke Bonding Guaranty Agreement”). Orinoco has not delivered the Replacement Bonds and neither it nor the Clarkes has made any of the agreed upon cash escrow payments. We filed a lawsuit against Orinoco and the Clarkes to enforce the terms of the Bonding Agreement and the Clarke Bonding Guaranty Agreement. The trial court initially granted summary judgment in favor of Orinoco and the Clarkes, dismissing our claims against Orinoco under the Bonding Agreement and against the Clarkes under the Clarke Bonding Guaranty Agreement. We filed an appeal with the trial court requesting a new trial on the summary judgment or modification of the judgment. On November 5, 2019, the trial court signed an order granting our motion for a new trial and vacating the prior summary judgment order. The parties are awaiting direction from the court on a new scheduling order and/or trial setting. The Initial Bonds, which are non-revocable, remain in effect.

In addition, Maritech and certain other interest owners have received decommissioning orders from BSEE and could receive additional decommissioning orders in the future. Such decommissioning orders received by Maritech and other interest owners relate to asset retirement obligations for certain properties in the Gulf of America. From time to time, we also receive demand notices from third parties related to certain corporate guarantees or other arrangements covering such decommissioning liabilities and other potential claims related to onshore decommissioning activities. While the ultimate outcome of such matters cannot be predicted at this time, if Maritech or other interest owners default, BSEE or third parties may seek to enforce certain corporate guarantees or third-party indemnity agreements against us for a portion of such decommissioning obligations, which may be significant. On February 13, 2025, Arena Energy, LLC (“Arena”) filed a complaint in U.S. District Court for the Southern District of Texas seeking indemnification from us and Maritech for decommissioning of a Maritech oil and gas platform in the Gulf of America. The estimated remaining decommissioning costs for such property is approximately $24.5 million, before TETRA’s bond proceeds of $8.1 million. At this stage of the dispute, we have not accrued a reserve for this contingency as we have not met the criteria specified in applicable accounting guidance.

If we become liable in the future for any decommissioning liability associated with any property covered by either an Initial Bond or Replacement Bond while such bonds are outstanding and any payment made to us under such bond is insufficient to satisfy such liability, the Bonding Agreement provides that Orinoco will pay us an amount equal to such deficiency. If Orinoco fails to pay any such amount, such amount must be paid by the Clarkes under the Clarke Bonding Guaranty Agreement. Our financial condition and results of operations may be negatively affected if we become liable for a significant portion of the decommissioning liabilities and Orinoco or the Clarkes are unable to cover any such deficiency.
With respect to certain properties in the Gulf of America, we have been advised that the cost of the decommissioning work to plug and abandon certain wells is projected to be significantly higher than the approximately $10.7 million bond supporting the liability, which was put in place by Maritech and other interest owners based on earlier cost estimates. We have also been advised more recently that Maritech’s prior working interest with respect those plugging and abandonment (“P&A”) costs are expected to exceed its share of the bond. In September 2024, P&A operations commenced pursuant to a cost sharing agreement among certain parties, excluding Maritech, for decommissioning certain properties in the Gulf of America. On November 3, 2025, Anadarko E&P Onshore LLC (“Anadarko”) filed a complaint in United States District Court for the Southern District of Texas seeking indemnification from us and Maritech for decommissioning costs exceeding $27.0 million asserting Maritech and TETRA are allegedly in breach of certain purported obligations to address plugging and abandonment and decommissioning obligations for certain outer continental shelf leases and related infrastructure located in the Gulf of America. While the ultimate outcome of this matter cannot be predicted, we could potentially be liable for an estimated amount in the range of $11.3 million to $27.0 million, before Maritech’s proportionate share of the bond proceeds (approximately $3.9 million), depending on the outcome of negotiations and whether other partners or property owners in the chain of title fulfill their respective obligations under their agreements. Additionally, we understand that in connection with the P&A operations being performed, Maritech and the other named obligees have made a demand on the related bond. We have made efforts to protect Maritech’s proportionate share of the bond proceeds, including demanding that the surety segregate or ensure that Maritech’s share is applied solely to satisfy its proportionate share of the decommissioning costs. We accrued liabilities of $7.4 million and $5.8 million related to this obligation as of December 31, 2025 and December 31, 2024, respectively. Due to the inherent subjectivity of the assessments and unpredictability of the outcomes of any legal proceedings, any amounts estimated or accrued may not represent the ultimate loss to the Company.

We intend to vigorously defend against the claims brought by Arena and Anadarko but we are presently unable to predict the duration, scope or result of these proceedings, as the litigation is in early stages. The estimates above exclude attorney fees, which cannot be reasonably determined.

In early 2018, we also closed the sale of our Offshore Segment to Epic Companies, LLC (“Epic Companies,” formerly known as Epic Offshore Specialty, LLC). Part of the consideration we received was a promissory note of Epic Companies in the original principal amount of $7.5 million (the “Epic Promissory Note”). At the end of August 2019, Epic Companies filed for bankruptcy and we recorded a reserve of $7.5 million for the full amount of the promissory note, including accrued interest, and certain other receivables in the amount of $1.5 million during the quarter ended September 30, 2019. The Epic Promissory Note became due on December 31, 2019 and neither Epic nor the Clarkes made payment. TETRA filed a lawsuit against the Clarkes on January 15, 2020 for breach of the promissory note guaranty agreement. In September 2020, the court granted TETRA’s Motion for Summary Judgment and entered Final Judgment in our favor, dismissing counterclaims by the Clarkes and awarding TETRA $7.9 million in damages. The Clarkes appealed the Final Judgment, and the court of appeals affirmed. Since obtaining the Final Judgment, TETRA has undertaken efforts to collect the judgment in Texas, Utah, Nevada, Massachusetts, and Georgia. TETRA continues to work on identifying potential Orinoco assets and/or engage with the Clarkes to resolve this dispute. During the year ended December 31, 2024, we received a $0.5 million settlement, which is included in other (income), net in our consolidated statement of operations. We cannot provide any assurance the Clarkes will pay the judgment or that they will not file for bankruptcy protection. If the Clarkes do file for bankruptcy protection, we likely would be unable to collect all, or even a significant portion of, the judgment owed to us.

Equity-Based Compensation
NOTE 13 — EQUITY-BASED COMPENSATION AND OTHER

Equity-Based Compensation

We have various equity incentive compensation plans that provide for the granting of restricted common stock, options for the purchase of our common stock, and other performance-based, equity-based compensation awards to our executive officers, key employees, nonexecutive officers, and directors. Stock options are exercisable for periods of up to ten years. Compensation cost for all share-based payments is based on the grant date fair value and is recognized in earnings over the requisite service period. Total equity-based compensation expense before tax attributed to equity incentive compensation plans for the three years ended December 31, 2025, 2024, and 2023, was $7.1 million, $6.6 million, and $10.6 million, respectively, and is included in general and administrative expense.

Stock Incentive Plans

In May 2007, our stockholders approved the adoption of the TETRA Technologies, Inc. 2007 Equity Incentive Compensation Plan. In May 2008, our stockholders approved the adoption of the TETRA Technologies, Inc. Amended and Restated 2007 Equity Incentive Compensation Plan, which among other changes, resulted in an increase in the maximum number of shares authorized for issuance. In May 2010, our stockholders approved further amendments to the TETRA Technologies, Inc. Amended and Restated 2007 Equity Incentive Compensation Plan (renamed as the 2007 Long Term Incentive Compensation Plan) which, among other changes, resulted in an additional increase in the maximum number of shares authorized for issuance. Pursuant to the 2007 Long Term Incentive Compensation Plan, we were authorized to grant up to 5,590,000 shares in the form of stock options (including incentive stock options and nonqualified stock options); restricted stock; bonus stock; stock appreciation rights; and performance awards to employees, and non-employee directors. As of February 2017, no further awards may be granted under the TETRA Technologies, Inc. Amended and Restated 2007 Equity Incentive Compensation Plan.

In May 2011, our stockholders approved the adoption of the TETRA Technologies, Inc. 2011 Long Term Incentive Compensation Plan. Pursuant to this plan, we were authorized to grant up to 2,200,000 shares in the form of stock options, restricted stock, bonus stock, stock appreciation rights, and performance awards to employees, and non-employee directors. On May 3, 2013, shareholders approved the TETRA Technologies, Inc. 2011 Long Term Incentive Compensation Plan that, among other things, increased the number of authorized shares to 5,600,000. On May 3, 2016, shareholders approved the TETRA Technologies, Inc. Third Amended and Restated 2011 Long Term Incentive Compensation Plan which, among other things, increased the number of authorized shares to 11,000,000.

In February 2018, the board of directors adopted the 2018 Inducement Restricted Stock Plan (“2018 Inducement Plan”). The 2018 Inducement Plan provides for grants of restricted stock up to a plan maximum of 1,000,000 shares.

    In May 2018, our stockholders approved the adoption of the TETRA Technologies, Inc. 2018 Equity Incentive Plan (“2018 Equity Plan”) and the TETRA Technologies, Inc. 2018 Non-Employee Director Equity Incentive Plan (“2018 Director Plan”). On May 2021, our stockholders approved the First Amended and Restated 2018 Equity Incentive Plan (the “Amended 2018 Equity Plan”), which amended the 2018 Equity Plan and terminated the 2018 Director Plan. In May 2023, our stockholders approved the Second Amended and Restated 2018 Equity Incentive Plan that, among other things, increased the number of authorized shares to 16,365,000. In June 2025, our stockholders approved the Third Amended and Restated 2018 Equity Incentive Plan which, among other things, increased the number of authorized shares to 20,635,000 shares in the form of stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, performance shares, other stock-based awards and cash-based awards to employees and non-employee directors.

Stock Options

We did not grant any stock options during the years ended December 31, 2025, 2024, and 2023. We have stock options outstanding for awards granted prior to 2023. The following is a summary of stock option activity for the year ended December 31, 2025:

Intrinsic value is the difference between the market value of our stock option multiplied by the number of stock options outstanding for those stock options where the market value exceeds their exercise price. During the year ended December 31, 2025, the total intrinsic value of stock options exercised was $0.9 million. Cash received from employees upon the exercise of stock options totaled $3.9 million for the year ended December 31, 2025. The company recognized $0.2 million of income tax benefits related to the exercise of awards during the year ended December 31, 2025. There were approximately 693,000, 1,000, and 206,000 options exercised during the years ended December 31, 2025, 2024, and 2023, respectively. At December 31, 2025, there is no unrecognized compensation cost for stock options as all stock options have vested.
Restricted Stock

    Restricted stock awards and restricted stock units are periodically granted to key employees, including grants for employment inducements, as well as to members of our Board of Directors. These awards historically have provided for vesting periods of up to three years. Non-employee director grants vest in full before the first anniversary of the grant. Upon vesting of restricted stock awards, shares are issued to award recipients. Restricted stock units may be settled in cash or shares at vest, as determined by the Compensation Committee or the Non-Executive Award Committee, as applicable. The following is a summary of activity for our outstanding restricted stock for the year ended December 31, 2025:

Total compensation cost recognized for restricted stock was $7.1 million, $6.6 million, and $10.6 million for the years ended December 31, 2025, 2024, and 2023, respectively. These amounts include nominal amounts for the years ended December 31, 2025 and 2024 and $5.0 million for the year ended December 31, 2023, for the portion of awards under short-term incentive plans and long-term incentive plans that were settled with restricted stock awards. Total unrecognized compensation cost at December 31, 2025, related to unvested restricted stock awards, is approximately $8.1 million which is expected to be recognized over a weighted-average remaining amortization period of 1.6 years. During the years ended December 31, 2025, 2024, and 2023, the total fair value of shares vested was $9.4 million, $8.4 million, and $4.7 million, respectively.

At December 31, 2025, net of options previously exercised pursuant to our various equity compensation plans, we have a maximum of 5,185,693 shares of common stock issuable pursuant to awards previously granted and outstanding and awards authorized to be granted in the future.

401(k) Plan

We have a 401(k) retirement plan (the “Plan”) that covers substantially all employees and entitles them to contribute up to 70% of their annual compensation, subject to maximum limitations imposed by the Internal Revenue Code. We match 50% of each employee’s contribution up to 8%. Participants will be 100% vested in employer match contributions after 3 years of service. In addition, we can make discretionary contributions which are allocable to participants in accordance with the Plan. Total expense related to our 401(k) plan was $2.6 million, $2.8 million, and $2.7 million for the years ended December 31, 2025, 2024, and 2023, respectively.

Deferred Compensation Plan

We provide our officers, directors, and certain key employees with the opportunity to participate in an unfunded, deferred compensation program. There were 4 participants in the program at December 31, 2025. Under the program, participants may defer up to 100% of their yearly total cash compensation. The amounts deferred remain our sole property, and we use a portion of the proceeds to purchase life insurance policies on the lives of certain of the participants. The insurance policies, which also remain our sole property, are payable to us upon the death of the insured. We separately contract with the participant to pay to the participant the amount of deferred compensation, as adjusted for gains or losses, invested in participant-selected investment funds. Participants may elect to receive deferrals and earnings at termination, death, or at a specified future date while still employed. Distributions while employed must be at least three years after the deferral election. The program is not qualified under Section 401 of the Internal Revenue Code. At December 31, 2025, the amounts payable under the plan approximated the value of the corresponding assets we owned.

Fair Value Measurements FAIR VALUE MEASUREMENTS
Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date” within an entity’s principal market, if any. The principal market is the market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity, regardless of whether it is the market in which the entity will ultimately transact for a particular asset or liability or if a different market is potentially more advantageous. Accordingly, this exit price concept may result in a fair value that may differ from the transaction price or market price of the asset or liability.

Under U.S. GAAP, the fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value. Fair value measurements should maximize the use of observable inputs and minimize the use of unobservable inputs, where possible. Observable inputs are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs may be needed to measure fair value in situations where there is little or no market activity for the asset or liability at the measurement date and are developed based on the best information available in the circumstances, which could include the reporting entity’s own judgments about the assumptions market participants would utilize in pricing the asset or liability.

Financial Instruments

Investments

We retained an interest in our former subsidiary, CSI Compressco LP (“CSI Compressco’), which was acquired by Kodiak on April 1, 2024, and we received shares of Kodiak in exchange for our common units in CSI Compressco in connection with such acquisition. In January 2025, we sold our Kodiak shares for proceeds of $19.0 million, net of transaction and broker fees. In addition, the Company received stock of Standard Lithium under the terms of agreements whereby Standard Lithium has the right to explore for, produce and extract lithium in our Arkansas leases and other additional potential resources in the Mojave region of California. Our investments in Kodiak, Standard Lithium, and, formerly, CSI Compressco, are recorded in investments on our consolidated balance sheets based on the quoted market stock price (Level 1 fair value measurements).

We also hold investments in convertible notes, common units and preferred units issued by two privately-held companies. Our investment in certain preferred units were recorded based on observable market-based inputs for preferred units issued to several investors during August through October 2024 (Level 2 fair value measurement). Our investment in convertible notes, common units and certain preferred units are recorded in our consolidated financial statements based on internal valuations with assistance from a third-party valuation specialist (Level 3 fair value measurement). The valuations are impacted by key assumptions, including the assumed probability and timing of potential debt or equity offerings. One of the convertible notes includes an option to convert the note into equity interests. The change in the fair value of the embedded option, as well as the preferred units and common units, are included in other (income) expense, net in our consolidated statements of operations. The change in the fair value of the convertible note, excluding the embedded option, is included in other comprehensive income (loss) in our consolidated statements of comprehensive income.

Derivative Contracts

We are exposed to financial and market risks that affect our businesses. We have concentrations of credit risk as a result of trade receivables owed to us primarily by companies in the energy industry. We have currency exchange rate risk exposure related to transactions denominated in foreign currencies as well as to investments in certain of our international operations. As a result of our variable rate debt facilities, we face market risk exposure related to changes in applicable interest rates. Our financial risk management activities may at times involve, among other measures, the use of derivative financial instruments, such as swap and collar agreements, to hedge the impact of market price risk exposures.

We entered into, and we may in the future enter into, short-term foreign currency forward derivative contracts with third parties as part of a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries. Although contracts pursuant to this program will serve as an economic hedge of the cash flow of our currency exchange risk exposure, they are not formally designated as hedge contracts or qualify for hedge accounting treatment. Accordingly, any change in the fair value of these derivative instruments during a period will be included in the determination of earnings for that period. The fair values of foreign currency derivative instruments are based on quoted market values (a Level 2 fair value measurement). We did not have foreign currency derivative instruments outstanding as of December 31, 2025 or 2024. During the years ended December 31, 2025, 2024, and 2023, we recognized $0.7 million, zero, and zero of
net losses, respectively, reflected in other (income) expense, net, associated with our foreign currency derivative program.

Impairments of Inventory and Long-Lived Assets

During 2025, we recorded a $3.6 million impairment of our former corporate office lease related to the relocation of our corporate headquarters and we recorded $0.6 million impairments of certain long-lived assets and right of use assets, within our Water & Flowback Services Segment. The fair values of right of use assets were estimated based on the discounted cash flows of our lease payments (a Level 3 fair value measurement) in accordance with the fair value hierarchy. The fair values of other long-lived assets was based on the estimated market values of similar equipment (a Level 3 fair value measurement).

During 2024, we recorded a $0.1 million impairment of our corporate office lease. During 2023, we recorded a $2.1 million impairment of a facility lease in Scotland within our Completion Fluids & Products Segment and we recorded a $0.8 million impairment of our corporate office lease. The fair values were estimated based on the discounted cash flows from our lease and sublease agreements (a Level 3 fair value measurement) in accordance with the fair value hierarchy.

During the year ended December 31, 2024, in part because we achieved three years of cumulative pretax income in the United States tax jurisdiction, after adjusting for permanent book and tax differences, which is a positive indication of our ability to generate sufficient future taxable income, we determined that there was sufficient positive evidence to conclude that it is more likely than not that additional deferred taxes are realizable and, therefore, released the valuation allowance accordingly.

We use the liability method for reporting income taxes, under which current and deferred tax assets and liabilities are recorded in accordance with enacted tax laws and rates. Under this method, at the end of each period, the amounts of deferred tax assets and liabilities are determined using the tax rate expected to be in effect when the taxes are actually paid or recovered. We establish a valuation allowance to reduce the deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. We considered all available evidence, both positive and negative, in determining whether, based on the weight of that evidence, a valuation allowance is needed for some portion or all of our deferred tax assets. In determining the need for a valuation allowance on our deferred tax assets we placed greater weight on recent and objectively verifiable current information, as compared to more forward-looking information that is used in valuating other assets on the balance sheet. While we have considered taxable income in prior years, future reversals of existing taxable temporary differences, future taxable income, and tax planning strategies in assessing the need for the valuation allowance, there can be no guarantee that we will be able to realize our net deferred tax assets. Significant components of our deferred tax assets and liabilities as of December 31, 2025 and 2024 are as follows:

Deferred tax liabilities

Net deferred tax assets$84,824 $93,237 

As of December 31, 2025, a significant portion of our deferred tax assets were United States (federal and state) assets, which include net operating loss carryforwards, tax credit carryforwards as well as temporary differences between GAAP and tax basis that will result in future tax deductions in excess of book. Significant management judgment is required in determining the period in which a reversal of a valuation allowance should occur. We are required to consider all available evidence, both positive and negative, such as historical levels of income and future forecasts of taxable income among other items, in determining whether a full or partial release of its valuation allowance is required.
The $0.3 million decrease in the valuation allowance during the year ended December 31, 2025 was primarily due to the decrease in deferred tax assets and associated $3.3 million valuation allowance related to the liquidation of our Canadian subsidiary mostly offset by the $2.1 million valuation allowance on the United States capital loss carryforward, which expires in 2029, and other changes various jurisdictions valuation allowances.

At December 31, 2025, we had deferred tax assets associated with U.S. federal, U.S. state, and non-U.S. net operating loss carryforwards equal to approximately $66.3 million, $8.5 million, and $9.1 million, respectively. In those jurisdictions in which NOLs are subject to an expiration period, our loss carryforwards, if not utilized, will expire at various dates from 2026 through 2041. Utilization of the NOLs, credit carryforwards and other tax attributes may be subject to a significant annual limitation if an “ownership change” under Section 382 of the Internal Revenue Code of 1986, as amended, has previously occurred or were to occur in the future.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
We are reliant on the continuous and uninterrupted operation of our various technology systems. User access to our sites and information technology systems are important elements of our operations, as are cloud security and protection against cyber incidents. In the ordinary course of our business, we collect and store sensitive data in our data centers and on our networks and private cloud networks, including intellectual property, proprietary business information, critical operating information, information regarding suppliers, customers and business partners, including certain personally identifiable information. In addition, the information technology infrastructure we use is important to the operation of our business and to our ability to perform day-to-day operations. Industrial control systems now control large-scale processes that can include multiple sites across long distances.

To assess, identify and manage material cybersecurity risks, we have endeavored to implement procedures, standards, and technical controls with the aim of protecting our networks and applications. We use internal and third-party tools and technologies to aid us in seeking to protect our network and internal systems from unauthorized access, intrusion, or disruption, including those described below.
Risk Assessment

Assessments are conducted across our systems, networks, and data infrastructure to identify potential cybersecurity threats and vulnerabilities. These assessments may include one or a combination of penetration testing, security audits, incident response planning, vendor risk assessments, and regulatory compliance assessments. Feedback from our maturity and technical assessments is incorporated into our systems and procedures through upgrades intended to further improve our security posture.

Incident Identification and Response

A monitoring and detection system has been implemented to help identify cybersecurity incidents. Our network activity, logs, and system behavior are monitored for anomalous or unauthorized activity using threat detection technologies. In addition, we have a cross-functional incident response plan, which includes an executive management team, established incident levels, and associated notification procedures, including escalation procedures upon discovery of material cybersecurity risks. We assess and update our security procedures and controls in an effort to address evolving threats and comply with applicable laws and regulations. We perform cybersecurity tabletop exercises to test the effectiveness of our incident response plan and implement post-incident “lessons learned” to enhance our response.

Cybersecurity Training and Awareness

Our cybersecurity program also focuses on providing training and awareness to our employees on cybersecurity best practices. Our training program includes computer-based training sessions assigned to employees and information sharing to educate employees on current cybersecurity-related topics. We also conduct phishing exercises to test and improve our employees’ awareness and response to potential cyber threats.

Access Controls

User access controls are used to limit unauthorized access to sensitive information and critical systems. In addition, we require multi-factor authentication for some, but not all, accounts. Users are provided with access consistent with the principle of least privilege, which requires that users be given no more access than necessary to complete their job functions.

We engage assessors, consultants, auditors, and other third parties in connection with the above processes. We recognize that third-party service providers introduce cybersecurity risks. In an effort to mitigate these risks, we conduct due diligence to evaluate their cybersecurity capabilities. Additionally, we endeavor to include cybersecurity requirements in our contracts with these providers and endeavor to require them to adhere to specific security standards and protocols.

Summary of Significant Accounting Policies (Policies)
 12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
Principles of Consolidation
Principles of Consolidation

Our consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Restricted Cash
Restricted Cash

Restricted cash is classified as a current asset when it is expected to be repaid or settled in the next twelve-month period. Restricted cash as of December 31, 2025 consists of $0.1 million held in escrow in connection with our Arkansas development.
Use of Estimates
Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclose contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, and impairments during the reporting period. Actual results could differ from those estimates, and such differences could be material.
Cash Equivalents
Cash Equivalents

We consider all highly liquid cash investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents include deposits in excess of federally insured amounts.
Financial Instruments
Financial Instruments

Financial instruments that subject us to concentrations of credit risk consist principally of trade receivables. Our policy is to evaluate, prior to providing goods or services, each customer’s financial condition and to determine the amount of open credit to be extended. We generally require appropriate, additional collateral as security for credit amounts in excess of approved limits. Our customers consist primarily of major, well-established oil and gas producers and independent oil and gas companies, as well as industrial, agricultural, road, and food and beverage purchasers for the chemicals we manufacture. Payment terms are on a short-term basis.

We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. Our risk management activities include the use of foreign currency forward purchase and sale derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected international operations.

We have no outstanding balance under our variable rate revolving credit facilities as of December 31, 2025. Outstanding balances on variable-rate bank credit facilities create market risk exposure related to changes in applicable interest rates.

The allowance for credit losses is determined on a specific identification basis when we believe that the collection of specific amounts owed to us is not probable, as well as a percentage of aged receivables based on historic losses. Changes in the allowance are as follows:

Inventories
Inventories

Inventories are stated at the lower of cost or net realizable value. Except for work in progress inventory, cost is determined using the weighted average method. The cost of work in progress is determined using the specific identification method.
Property, Plant, and Equipment
Property, Plant, and Equipment

Property, plant, and equipment are stated at cost. Expenditures that increase the useful lives of assets are capitalized. The cost of repairs and maintenance is charged to operations as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which are generally as follows:
Buildings
25 years
Machinery and equipment
3 – 10 years
Automobiles and vehicles
4 years
Chemical plants
15 years

Leasehold improvements are depreciated over the shorter of the remaining term of the associated lease or its useful life. Depreciation expense, excluding impairments and other charges, for the years ended December 31, 2025, 2024, and 2023 was $28.5 million, $28.4 million, and $29.2 million, respectively.

Construction in progress as of December 31, 2025 and 2024 consisted primarily of our bromine processing plant in Arkansas, equipment fabrication projects and early production facilities. During the years ended December 31, 2025 and 2024, we capitalized $4.5 million and $1.2 million of interest expense, respectively. We did not capitalize interest during the year ended December 31, 2023.
Intangible Assets Other Than Goodwill
Intangible Assets other than Goodwill

Customer relationships, trademarks, tradenames, marketing rights and other intangible assets are amortized on a straight-line basis over their estimated useful lives, with remaining useful lives up to 8 years. Amortization of intangible assets was $3.5 million, $4.2 million, and $4.5 million for the years ended December 31, 2025, 2024, and 2023, respectively, and is included in depreciation, amortization and accretion in our consolidated statements of operations. The estimated future annual amortization expense of intangible assets is $3.4 million for 2026, $3.2 million for 2027, $2.7 million for 2028, $2.4 million for 2029, $2.4 million for 2030, and $7.4 million thereafter. See Note 4 - “Intangibles” for additional information.

Intangible assets other than goodwill are tested for recoverability whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. In such an event, we will determine the fair value of the asset using an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we will recognize a loss for the difference between the carrying value and the estimated fair value of the intangible asset.
Leases
Leases

As a lessee, unless the lease meets the criteria of short-term and is excluded per our policy election described below, we initially recognize a lease liability and related right-of-use asset on the commencement date. The right-of-use asset represents our right to use an underlying asset and the lease liability represents our obligation to make lease payments to the lessor over the lease term.    

Long-term operating leases are included in operating lease right-of-use assets, operating lease liabilities - current portion, and operating lease liabilities in our consolidated balance sheets. Long-term finance leases are included in machinery and equipment, accrued liabilities and other and other liabilities in our consolidated balance sheets. We determine whether a contract is or contains a lease at inception of the contract. Where we are a lessee in a contract that includes an option to extend or terminate the lease, we include the extension period or exclude the period covered by the termination option in our lease term in determining the right-of-use asset and lease liability, if it is reasonably certain that we would exercise the option.

As an accounting policy election, we do not include short-term leases on our balance sheets. Short-term leases include leases with a term of 12 months or less, inclusive of renewal options we are reasonably certain to exercise. The lease payments for short-term leases are included as operating lease costs on a straight-line basis over the lease term in cost of revenues or general and administrative expense based on the use of the underlying asset. We recognize lease costs for variable lease payments not included in the determination of a lease liability in the period in which an obligation is incurred.

Our operating and finance leases are recognized at the present value of lease payments over the lease term. When the implicit discount rate is not readily determinable, we use our incremental borrowing rate to calculate the discount rate used to determine the present value of lease payments. Consistent with other long-lived assets or asset groups that are held and used, we test for impairment of our right-of-use assets when impairment indicators are present.
Impairments of Inventory and Long-Lived Assets
Impairments of Inventory and Long-Lived Assets

Impairments of inventory and long-lived assets, including identified intangible assets, are determined periodically when indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is based on our judgments as to the future undiscounted operating cash flows to be generated from these assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related asset, an impairment is recognized for the excess of the carrying value over its fair value. Assets held for disposal are recorded at the lower of carrying value or estimated fair value less estimated selling costs. See Note 5 - “Impairments and Other Charges” for additional discussion of recorded impairments.
Revenue Recognition
Revenue Recognition

Performance Obligations. Revenue is generally recognized when we transfer control of our products or services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services to our customers. We receive cash equal to the invoice price for most sales of product and services and payment terms typically range from 30 to 60 days from the date we invoice our customer. Since the period between when we deliver products or services and when the customer pays for such products or services is not expected to exceed one year, we have elected not to calculate or disclose a financing component for our customer contracts.

    Depending on the terms of the arrangement, we may also defer the recognition of revenue for a portion of the consideration received because we have to satisfy a future performance obligation.

    For any arrangements with multiple performance obligations, we use management’s estimated selling price to determine the stand-alone selling price for separate performance obligations. For revenue associated with mobilization of service equipment as part of a service contract arrangement, such revenue, if significant, is deferred and amortized over the estimated service period.
    Product Sales. Product sales revenues are recognized at a point in time when we transfer control of our product offerings to our customers, generally when we ship products from our facility to our customer. The product sales for our Completion Fluids & Products Segment consist primarily of CBFs, additives, and associated manufactured products. Certain customers have bill-and-hold arrangements. Revenue for bill-and-hold arrangements is recognized when control transfers to the customer, even though the customer may not have physical possession of the product. Control transfers when there is a substantive reason for the arrangement, the product is identified as belonging to the customer, is ready for physical transfer, and cannot be directed for use by anyone but the customer. Product sales for our Water & Flowback Services Segment are typically attributed to specific performance obligations within certain production testing service arrangements.

    Services. Service revenues represent revenue recognized over time, as our customer arrangements typically provide agreed upon day rates and we recognize service revenue based upon the number of days services have been performed. Service revenue recognized over time is associated with a majority of our Water & Flowback Services Segment arrangements, and a small portion of Completion Fluids & Products Segment revenue that is associated with completion fluid service arrangements. Our customer contracts are generally for terms of one year or less. The majority of the service arrangements in the Water & Flowback Services Segment are for a period of 90 days or less.

    Sales taxes, value added taxes, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We have elected to recognize the cost for freight and shipping costs as part of cost of product sales when control over our products (i.e., delivery) has transferred to the customer.

    Use of Estimates. In recognizing revenue for variable consideration arrangements, the amount of variable consideration recognized is limited so that it is probable that significant amounts of revenues will not be reversed in future periods when the uncertainty is resolved. For products returned by the customer, we estimate the expected returns based on an analysis of historical experience. For volume discounts earned by the customer, we estimate the discount (if any) based on our estimate of the total expected volume of products sold or services to be provided to the customer during the discount period. In certain contracts for the sale of CBFs, we may agree to issue credits for the repurchase of reclaimable used fluids from certain customers at an agreed price that is based on the condition of the fluids and, in some cases, the volume of fluids sold.

    Contract Assets and Liabilities. We consider contract assets to be trade accounts receivable when we have an unconditional right to consideration and only the passage of time is required before payment is due. In certain instances, particularly those requiring customer specific documentation prior to invoicing, our invoicing of the customer is delayed until certain documentation requirements are met. In those cases, we recognize a contract asset rather than a billed trade accounts receivable until we are able to invoice the customer. Contract assets, along with billed trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets.

    We classify contract liabilities as unearned income in our consolidated balance sheets. Unearned income includes amounts in which the Company was contractually allowed to invoice prior to satisfying the associated performance obligations.
Operating Costs
Operating Costs

Cost of product sales includes direct and indirect costs of manufacturing and producing our products, including raw materials, fuel, utilities, labor, overhead, repairs and maintenance, materials, services, transportation, warehousing, equipment rentals, insurance, and certain taxes. Cost of services includes operating expenses we incur in delivering our services, including labor, equipment rental, fuel, repair and maintenance, transportation, overhead, insurance, and certain taxes. We include in product sales revenues the reimbursements we receive from customers for shipping and handling costs. Shipping and handling costs are included in cost of product sales. Amounts we incur for “out-of-pocket” expenses in the delivery of our services are recorded as cost of services. Reimbursements for “out-of-pocket” expenses we incur in the delivery of our services are recorded as service revenues. Depreciation, amortization, and accretion includes depreciation expense for all of our facilities, equipment and vehicles, amortization expense on our intangible assets, and accretion expense related to our decommissioning and other asset retirement obligations.

We include in general and administrative expense all costs not identifiable to our specific product or service operations, including segment and general corporate overhead, professional services, corporate office costs, sales and marketing expenses, insurance, and certain taxes.
Collaborative Arrangement
Collaborative Arrangement

We are pursuing low-carbon energy initiatives that leverage our fluids core chemistry competencies and our significant mineral resources, including our brine leases in Southwest Arkansas. In June 2023, we entered into a memorandum of understanding with Saltwerx, LLC (“Saltwerx”), an indirect wholly owned subsidiary of ExxonMobil Corporation, relating to a newly-proposed brine unit in the Smackover Formation in Southwest Arkansas and potential bromine and lithium production from brine produced from the unit. The memorandum of understanding includes an allocation of certain costs for the drilling of a brine production test well and other development operations, including front-end engineering and design studies for bromine and lithium production facilities.

During the years ended December 31, 2025 and 2024, we capitalized approximately $45.2 million and $22.4 million, respectively, of costs, net of reimbursements from our partner, associated with the development of our properties in Arkansas, excluding capitalized interest, which are included in capital expenditures for our Completion Fluids & Products Segment. During the year ended December 31, 2023, we incurred $12.1 million of exploration and pre-development costs and recorded $9.3 million in reimbursements associated with this arrangement. This income is included in other (income) expense, net in our consolidated statements of operations.
Loss Contingencies
Loss Contingencies

We and certain of our subsidiaries are involved, in the normal course of business, in lawsuits, claims and other legal proceedings and audits. We accrue reserves for these matters when we believe it is probable that a liability has been incurred and the liability can be reasonably estimated. In addition, we disclose exposure to certain losses in excess of the amount recorded on the balance sheet for these matters if it is reasonably possible that an additional material loss may be incurred. We review such loss contingencies on an ongoing basis. Loss contingencies are based on judgments made by management with respect to the likely outcome of these matters and are adjusted as appropriate. Management’s judgments could change based on new information, changes in, or interpretations of, laws or regulations, changes in management’s plans or intentions, opinions regarding the outcome of legal proceedings or other factors. See Note 11 - Commitments and Contingencies - Litigation and Contingencies of Discontinued Operations for additional information.
Equity-Based Compensation
Equity-Based Compensation
    We have various equity incentive compensation plans which provide for the granting of restricted common stock, options for the purchase of our common stock, and other performance-based, equity-based compensation awards to our executive officers, key employees, nonexecutive officers, and directors. Upon the vesting of restricted stock awards or exercise of employee stock options, we issue new shares of common stock. Forfeitures of equity-based compensation awards are recognized as they occur. Total equity-based compensation expense, net of taxes, for the years ended December 31, 2025, 2024, and 2023, was $6.8 million, $6.3 million, and $10.4 million, respectively. For further discussion of equity-based compensation, see Note 13 – “Equity-Based Compensation and Other”
Mineral Resources Arrangements
Mineral Resources Arrangements

    We are party to agreements in which Standard Lithium Ltd. (“Standard Lithium”) has the right to explore, produce and extract lithium in our Arkansas leases as well as additional potential resources in the Mojave region of California. The Company received cash and stock of Standard Lithium (NYSE:SLI) under the terms of the arrangements. The cash and stock component of consideration received is initially recorded as unearned income based on the quoted market price at the time the stock is received, then recognized in income over the contract term. Deferred income balances were $1.0 million and $1.0 million as of December 31, 2025 and 2024, respectively, associated with the consideration received from Standard Lithium and are included in accrued liabilities and other in our consolidated balance sheets. During the years ended December 31, 2025, 2024, and 2023, income from this arrangement was $1.0 million, $1.6 million, and $3.0 million, respectively, from the value of cash and stock received, and $2.4 million, $(0.4) million and $(1.0) million, respectively, for unrealized gains (losses) on changes in the value of Standard Lithium stock held. See Note 14 - “Fair Value Measurements” for further discussion.
Income Taxes
Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis amounts. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates is recognized as income or expense in the period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. A portion of the carrying value of certain deferred tax assets are subject to a valuation allowance. See Note 15 – “Income Taxes” for further discussion.

    The global intangible low-taxed income (“GILTI’) provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. We elected to account for GILTI as a period cost in the year the tax is incurred.

We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than fifty percent likely to be realized upon ultimate settlement with the related tax authority. We recognize interest expense and penalties on uncertain tax positions and income tax deficiencies as a component of income tax (benefit) expense.

Tax Benefits Preservation Plan

On February 28, 2023, the Board of Directors adopted a Tax Benefits Preservation Plan (the “Tax Plan”) designed to preserve the availability of the Company’s existing net operating loss carryforwards (“NOLs”) and other tax attributes (collectively, the “Tax Attributes”). The Board of Directors approved Amendment No. 1 (the “Amendment”) to the Tax Plan on February 19, 2026 and the Company entered into the Amendment on February 25, 2026. The Amendment extends the expiration date of the Tax Plan from February 28, 2026 to February 28, 2029 (subject to other earlier termination events).The Tax Attributes may be utilized in certain circumstances to reduce our future income tax obligations. However, our ability to utilize the Tax Attributes would be substantially limited if an “ownership change” under Section 382 (“Section 382”) of the Internal Revenue Code of 1986, as amended (the “Code”) were to occur. In general, an ownership change under Section 382 occurs if one or more stockholders (or group of stockholders) who are each deemed to own at least 5% of the corporation’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a testing period (generally, a rolling three-year period). The Tax Plan contributes to the preservation of the Company’s Tax Attributes by reducing the risk that an ownership change under Section 382 occurs.

In adopting the Tax Plan, the Board of Directors declared a dividend of one Series A Junior Participating Preferred Stock purchase right (the “Rights”) for each outstanding share of Common Stock pursuant to the terms of the Tax Plan. Initially, each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share, of the Company (the “Preferred Stock”) at a price of $20.00 per one one-thousandth of a share of Preferred Stock (the “Purchase Price”), subject to adjustment. The Rights will cause substantial dilution to a person or group that acquires 4.99% or more of the Common Stock (or to a person or group that already owns 4.99% or more of the Company’s Common Stock if such person or group acquires additional shares representing 2% of the Company’s then outstanding shares of Common Stock) without prior approval from the Board of Directors.

The Rights will expire at the earliest of: (i) the close of business on February 28, 2029 (the “Final Expiration Date”); (ii) the time at which the Rights are redeemed pursuant to the Tax Plan, (iii) the time at which the Rights are exchanged pursuant to the Tax Plan; (iv) the closing of any merger or other acquisition transaction involving the Company pursuant to an agreement as described in the penultimate paragraph of Section 1.3 of the Tax Plan; (v) the close of business on the effective date of the repeal of Section 382 of the Code if the Board determines that the
Tax Plan is no longer necessary or desirable for the preservation of the Tax Attributes; or (vi) the close of business on the first day of a taxable year of the Company following a Board determination that no Tax Attributes may be carried forward or otherwise utilized.

The Tax Plan adopted by the Board of Directors is similar to plans adopted by other publicly held companies with significant NOLs or other substantial Tax Attributes and is not designed to prevent any action that the Board of Directors determines to be in the best interest of the Company and its stockholders. At the Company’s 2023 annual meeting of stockholders held on May 24, 2023, the Company’s stockholders ratified the adoption of the Tax Plan. The Company intends to submit the Amendment to its stockholders for ratification at the 2026 annual meeting of stockholders.

The Rights are in all respects subject to and governed by the provisions of the Tax Plan. The foregoing summary provides only a general description of the Tax Plan and does not purport to be complete. The Tax Plan, which specifies the terms of the Rights and includes as an exhibit the Form of Right Certificate. The foregoing summary should be read together with the entire Tax Plan and the Amendment and is qualified in its entirety by reference to the Tax Plan and the Amendment.

In connection with the Amendment, the Company filed a Certificate of Designation of Series A Junior Participating Preferred Stock of the Company with the Secretary of State of the State of Delaware, which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.
Noncontrolling Interests
Noncontrolling Interests

Noncontrolling interests represent third-party ownership in the net assets of the Company’s consolidated subsidiaries and are presented as a component of equity. The Company’s noncontrolling interests as of December 31, 2025 and 2024 consists primarily of the outside ownership of subsidiaries in Africa.
Accumulated Other Comprehensive Income (Loss)
Accumulated Other Comprehensive Income (Loss)

Certain of our international operations maintain their accounting records in the local currencies that are their functional currencies. For these operations, the functional currency financial statements are converted to United States dollar equivalents, with the effect of the foreign currency translation adjustment reflected as a component of accumulated other comprehensive income (loss). Accumulated other comprehensive income (loss) is included in equity in the accompanying consolidated balance sheets and consists of the cumulative currency translation adjustments associated with such international operations.

In addition, the change in the fair value of the convertible note, excluding the embedded option, is included in other comprehensive income (loss) in our consolidated statements of comprehensive income. The portion of our accumulated other comprehensive income (loss) attributable to the convertible note is subject to reclassifications to net income if or when we settle the convertible note. See Note 8 – “Investments” for further discussion of the convertible note.
Income (Loss) per Common Share
Income (Loss) per Common Share

The calculation of basic and diluted earnings per share excludes losses attributable to noncontrolling interests. The calculation of basic earnings per share excludes any dilutive effects of equity awards. The calculation of diluted earnings per share includes the effect of equity awards, if dilutive, which is computed using the treasury stock method during the periods such equity awards were outstanding. See Note 16 – “Net Income Per Share” for further discussion of shares outstanding.
Foreign Currency Translation
Foreign Currency Translation

We have designated the Euro, the British pound, the Canadian dollar, and the Brazilian real as the functional currencies for our operations in Finland and Sweden, the United Kingdom, Canada, and Brazil, respectively. The United States dollar is the designated functional currency for all of our other significant non-U.S. operations. The cumulative translation effects of translating the applicable accounts from the functional currencies into the U.S. dollar at current exchange rates are included as a separate component of equity. Foreign currency exchange losses are included in other (income) expense, net, and totaled $8.3 million, $3.8 million, and $3.5 million for the years ended December 31, 2025, 2024, and 2023, respectively. Foreign currency exchange losses during
the year ended December 31, 2025 include recognition of a $9.5 million cumulative foreign currency translation adjustment loss, which was reclassified from accumulated other comprehensive loss due to the dissolution of our former subsidiary in Canada during 2025.
Fair Value Measurements
Fair Value Measurements

We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized on a recurring basis in the determination of the carrying values of certain investments. See Note 8 – “Investments” and Note 14 - “Fair Value Measurements” for further discussion.

Fair value measurements are also utilized on a nonrecurring basis in certain circumstances, such as in the allocation of purchase consideration for acquisition transactions to the assets and liabilities acquired, including intangible assets and goodwill (a Level 3 fair value measurement), the initial recording of our asset retirement obligations, and for the impairment of long-lived assets, including goodwill (a Level 3 fair value measurement).
New Accounting Pronouncements
New Accounting Pronouncements

Recently Adopted Accounting Pronouncement

Effective January 1, 2025, we adopted ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, on a prospective basis. This standard requires enhanced disclosures of income taxes, including disaggregated effective tax rate reconciliation by specific categories in both dollars and percentages. income taxes paid disaggregated by jurisdiction, and qualitative explanations for significant reconciling items. The adoption of ASU 2023-09 did not impact our recognition or measurement of income taxes but resulted in expanded disclosures as reflected in Note 2 - “Summary of Significant Accounting Policies” and Note 15 - “Income Taxes.”

Standards not yet adopted

In December 2025, the FASB issued Accounting Standards Update (“ASU”) 2025-12, Codification Improvements, as part of its ongoing project to clarify and correct various areas of U.S. GAAP. The amendments span multiple Topics and include clarifications related to diluted earnings per share, lease receivable disclosures, and transfers of receivables, among others. These changes are not expected to significantly affect current accounting practices. Effective dates vary depending on the underlying Topic. We do not expect ASU 2025-12 to have a material impact on our consolidated financial statements as the amendments clarify existing guidance, but we will continue to monitor its applicability

In December 2025, the FASB also issued ASU 2025-11, “Narrow-Scope Improvements” (“ASU 2025-11”), which clarifies required interim disclosures. ASU 2025-11 addresses the form and content of interim financial statements and footnotes prepared in accordance with GAAP, lists the interim disclosures required by all other
Codification topics, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and may be applied prospectively or retrospectively. The adoption of the standard will not have an impact on our consolidated statements of operations or balance sheets as the standard only impacts interim disclosures.

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets” (“ASU 2025-05”), which provides entities with optional relief when estimating expected credit losses for current accounts receivable arising from transactions accounted for under Accounting Standards Codification 606. The amendments permit entities to apply a practical expedient that assumes current economic conditions as of the balance sheet date remain unchanged for the remaining life of the asset. The Company expects to adopt the practical expedient effective January 1, 2026 and is assessing the impact of ASU 2025-05 to its consolidated financial statements upon adoption.

In November 2024, the FASB issued ASU 2024-03, “Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40)” ("ASU 2024-03"). ASU 2024-03 requires additional disclosures about certain expenses included in the income statement, including purchases of inventory, employee compensation, intangible asset amortization and depreciation. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027 with early adoption permitted. The Company is currently assessing the impact of ASU 2024-03 and does not expect a significant impact to its consolidated financial statements upon adoption as the standard expands disclosures.
