Notes to Consolidated Financial Statements

(Unaudited)

NOTE 1 – ORGANIZATION, BASIS OF PRESENTATION, AND SIGNIFICANT ACCOUNTING POLICIES

Organization

We are an energy services and solutions company operating on six continents, focused on calcium chloride, completion fluids and associated products and services, comprehensive water management solutions, frac flowback, and production well testing. We were incorporated in Delaware in 1981 and are composed of two segments – Completion Fluids & Products Division and Water & Flowback Services Division. Unless the context requires otherwise, when we refer to “we,” “us,” and “our,” we are describing TETRA Technologies, Inc. and its subsidiaries on a consolidated basis.

Presentation

Our unaudited consolidated financial statements include the accounts of our wholly owned or controlled subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The information furnished reflects all normal recurring adjustments, which are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods. Operating results for the period ended September 30, 2023 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2023.

We have reflected the operations of our former Compression Division and Offshore Division as discontinued operations for all periods presented. See Note 2 - “Discontinued Operations” for further information. Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate solely to continuing operations and exclude all discontinued operations.

The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission (“SEC”) and do not include all information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2022 and notes thereto included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 27, 2023 (the “2022 Annual Report”).

Tax Benefits Preservation Plan

On February 28, 2023, the Board of Directors adopted a Tax Benefits Preservation Plan (the “Tax Plan”) designed to protect the availability of the Company’s net operating loss carryforwards (“NOLs”) and other tax attributes (collectively, the “Tax Attributes”), which may be utilized in certain circumstances to reduce the Company’s future income tax obligations. The Tax Plan is intended to reduce the likelihood that any changes in the Company’s investor base would limit the Company’s future use of its Tax Attributes as a result of the Company experiencing an “ownership change” under Section 382 (“Section 382”) of the Internal Revenue Code of 1986, as amended (the “Code”). If a corporation experiences an “ownership change,” any NOLs, losses or deductions attributable to a “net unrealized built-in loss” and other Tax Attributes could be substantially limited, and timing of the usage of such Tax Attributes could be substantially delayed. A corporation generally will experience an ownership change 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).

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

8

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, 2026 (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 benefits 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 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 Exhibit A the Form of Certificate of Designation of Series A Junior Participating Preferred Stock of the Company and as Exhibit B the Form of Right Certificate, is attached to the Company’s Current Report on Form 8-K, which was filed with the SEC on March 1, 2023, as Exhibit 4.1 and is incorporated herein by reference. The foregoing summary should be read together with the entire Tax Plan and is qualified in its entirety by reference to the Tax Plan.

Mineral Resources Arrangement

We have rights to the brine underlying our approximately 40,000 gross acres of brine leases in the Smackover Formation in Southwest Arkansas, including rights to the bromine and lithium contained in the brine. We recognized approximately $3.8 million and $6.8 million of expense during the three-month and nine-month periods ended September 30, 2023, respectively, and $0.9 million and $3.5 million of expense during the three-month and nine-month periods ended September 30, 2022, respectively, for exploration and pre-development costs representing expenditures incurred to evaluate potential future development of our lithium and bromine properties in Arkansas. We are also party to agreements whereby Standard Lithium Ltd. (NYSE: SLI) (“Standard Lithium”) has the right to explore for, and an option to acquire the rights to produce and extract, lithium in our Arkansas leases and other potential resources in the Mojave region of California. Standard Lithium delivered a notice to exercise this option to acquire those lithium rights in our Arkansas leases on October 6, 2023.

In June 2023, we entered into a memorandum of understanding (“MOU”) with Saltwerx LLC (“Saltwerx”), an indirect wholly owned subsidiary of a Fortune 500 company, 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. We filed an amended brine unit application (“the Application”) covering approximately 6,138 acres, which expands the size of the unit area and also combines brine acreage that was previously leased by each of TETRA and Saltwerx (“the Brine Unit”), with the Arkansas Oil & Gas Commission (“AOGC”). On September 26, 2023, the AOGC held a public hearing and unanimously approved our application to establish the Brine Unit. On October 17, 2023, the AOGC issued formal orders establishing the Brine Unit and integrating all unleased parties within the Brine Unit, subject to a 60-day statutory election period for each unleased party, to elect whether or not to participate and share in costs of development of the Brine Unit. If no such election is made within the election period, such unleased parties will be deemed integrated within the Brine Unit as described in the formal orders. The MOU includes provisions relating to: (i) initial brine ownership percentages within the Brine Unit, including the bromine and lithium contained in the brine, (ii) the transfer of certain leased acres outside the proposed Brine Unit from the Company to Saltwerx after the expiration of the 60-day election period, (iii) Saltwerx reimbursing the Company for certain expenses incurred by the Company to date regarding the development of leased acreage to be included in the Brine Unit, and (iv) an allocation of certain future 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.

Significant Accounting Policies

Our significant accounting policies are described in the notes to our consolidated financial statements for the year ended December 31, 2022 included in our 2022 Annual Report. There have been no significant changes in our accounting policies or the application thereof during the third quarter of 2023.

Use of Estimates

The preparation of financial statements in conformity with 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.

Reclassifications

Certain previously reported financial information has been reclassified to conform to the current year's presentation. The impact of reclassifications was not significant to the prior year's overall presentation.

Foreign Currency Translation

We have designated the Euro, the British pound, the Canadian dollar, the Brazilian real, and the Mexican peso as the functional currencies for our operations in Finland and Sweden, the United Kingdom, Canada, Brazil, and certain of our operations in Mexico, respectively. The United States dollar is the designated functional currency for all of our other non-U.S. operations. The cumulative translation effects of translating the applicable accounts from the functional currencies into the United States dollar at current exchange rates are included as a separate component of equity. Foreign currency exchange (gains) losses are included in other (income) expense, net and totaled less than $0.1 million and $0.3 million during the three and nine months ended September 30, 2023, respectively, and $(1.1) million and $(2.7) million during the three and nine months ended September 30, 2022, respectively.

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 - “Fair Value Measurements” for further discussion. Fair value measurements are also utilized on a nonrecurring basis in certain circumstances, including the impairment of long-lived assets (a Level 3 fair value measurement).

New Accounting Pronouncements

Standards adopted during 2023

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the previously-used incurred loss methodology, which will result in the more timely recognition of losses on financial instruments not accounted for at fair value through net income. The provisions require credit impairments to be measured over the contractual life of an asset and developed with consideration for past events, current conditions, and forecasts of future economic information. Credit impairment will be accounted for as an allowance for credit losses deducted from the amortized cost basis at each reporting date. Updates at each reporting date after initial adoption will be recorded through selling, general, and administrative expense. On January 1, 2023, we adopted ASU 2016-13. The adoption of this standard did not have a material impact on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” During the three months ended June 30, 2023, our asset-based credit agreement and term credit agreement were amended to replace LIBOR and Eurodollar rates with the secured overnight financing rate (“SOFR”). There were no significant costs associated with the amendments and the amendments did not have a significant impact on our consolidated financial statements.

NOTE 2 – DISCONTINUED OPERATIONS

On March 1, 2018, we closed a series of related transactions that resulted in the disposition of our Offshore Division, consisting of our Offshore Services and Maritech segments. Our former Offshore Division is reported as discontinued operations for all periods presented. Our consolidated balance sheets and consolidated statements of operations report discontinued operations separate from continuing operations. Our consolidated statements of comprehensive income, statements of equity and statements of cash flows combine continuing and discontinued operations. Our loss from discontinued operations for the three and nine months ended September 30, 2023 consists primarily of general and administrative expense associated with our former Offshore Division. A summary of additional financial information related to our discontinued operations is as follows:

NOTE 3 – REVENUE FROM CONTRACTS WITH CUSTOMERS

Our contract asset balances, primarily associated with contractual invoicing milestones and/or customer documentation requirements, were $30.7 million and $33.1 million as of September 30, 2023 and December 31, 2022, respectively. Contract assets, along with billed trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets.

12

Unearned income includes amounts in which the Company was contractually allowed to invoice prior to satisfying the associated performance obligations. We are also party to agreements whereby Standard Lithium has the right to explore for, and an option to acquire the rights to produce and extract, lithium in our Arkansas leases and other potential resources in the Mojave region of California. The Company receives cash and stock of Standard Lithium 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. Unearned income balances were $4.0 million and $3.7 million as of September 30, 2023 and December 31, 2022, respectively, and vary based on the timing of (i) invoicing, (ii) performance obligations being met and (iii) the receipt of stock and cash from Standard Lithium. Unearned income is included in accrued liabilities and other in our consolidated balance sheets. During the three-month and nine-month periods ended September 30, 2023 and September 30, 2022, contract costs were not significant.

We recognized approximately $1.2 million and $1.6 million of revenue during the three-month and nine-month periods ended September 30, 2023, respectively, and $2.6 million and $1.7 million of revenue during the three-month and nine-month periods ended September 30, 2022, respectively, deferred in unearned income as of the beginning of the period. We also recognized approximately $0.7 million and $2.4 million of income during the three-month and nine-month periods ended September 30, 2023, respectively, and $0.9 million and $2.4 million of income during the three-month and nine-month periods ended September 30, 2022, respectively, related to the Standard Lithium arrangements deferred in unearned income as of the beginning of the period and included in other income, net in our consolidated statements of operations.

We disaggregate revenue from contracts with customers into Product Sales and Services within each segment, as noted in our two reportable segments in Note 10 - “Industry Segments.” In addition, we disaggregate revenue from contracts with customers by geography based on the following table below.

(2) Net of unamortized deferred financing costs of $1.1 million as of December 31, 2022. Deferred financing costs of $0.7 million as of September 30, 2023 were classified as other long-term assets on the accompanying consolidated balance sheet as there was no outstanding balance on our asset-based credit agreement.

Term Credit Agreement

    As of September 30, 2023, we had $156.7 million outstanding, net of unamortized discounts and unamortized deferred financing costs under our term credit agreement (“Term Credit Agreement”). The Term Credit Agreement requires us to offer to prepay up to 50% of Excess Cash Flow (as defined in the Term Credit Agreement) from the most recent full fiscal year within five business days of filing our Annual Report. If our Leverage Ratio (as

14

defined in the Term Credit Agreement) at year-end is less than 2.00 to 1.00, the prepayment requirement is decreased to 25%. If our Leverage Ratio at year-end is less than 1.50 to 1.00, then no prepayment is required.

The Term Credit Agreement was amended in June 2023 to remove references to LIBOR and Eurodollar rates. Borrowings under the Term Credit Agreement bear interest at a rate per annum equal to, at the option of TETRA, either (i) SOFR (subject to a 1% floor) plus a margin of 6.25% per annum or (ii) a base rate plus a margin of 5.25% per annum. As of September 30, 2023, the interest rate per annum on borrowings under the Term Credit Agreement is 11.68%. In addition to paying interest on the outstanding principal under the Term Credit Agreement, TETRA is required to pay a commitment fee in respect of the unutilized commitments at the rate of 1.0% per annum, paid quarterly in arrears based on utilization of the commitments under the Term Credit Agreement.

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

ABL Credit Agreement

As of September 30, 2023, our asset-based credit agreement (“ABL Credit Agreement”) provides for a senior secured revolving credit facility of up to $80.0 million, with a $20.0 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, a swingline loan sublimit of $11.5 million, and a $15.0 million sub-facility subject to a borrowing base consisting of certain trade receivables and inventory in the United Kingdom.

As of September 30, 2023, we had no balance outstanding and $11.5 million in letters of credit and guarantees under 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 $68.5 million under this agreement.

The ABL Credit Agreement was amended in May 2023 to remove references to LIBOR. Borrowings under the ABL Credit Agreement bear interest at a rate per annum equal to, at the option of TETRA, either (i) SOFR plus 0.10%, (ii) a base rate plus a margin based on a fixed charge coverage ratio, (iii) the Daily Simple Risk Free Rate plus 0.10%, or (iv) with respect to borrowings denominated in Sterling, the Daily Simple Risk Free Rate for Sterling plus 0.0326%. The base rate is determined by reference to the highest of (a) the prime rate of interest as announced from time to time by JPMorgan Chase Bank, N.A. (b) the Federal Funds Effective Rate (as defined in the ABL Credit Agreement) plus 0.5% per annum and (c) SOFR (adjusted to reflect any required bank reserves) for a one-month period on such day plus 1.0% per annum. 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 ranging from 0.375% to 0.5% per annum, paid monthly in arrears based on utilization of the commitments under the ABL Credit Agreement. TETRA is also required to pay a customary letter of credit fee equal to the applicable margin on LIBOR-based 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.

Argentina Credit Agreement

In January 2023, the Company entered into a revolving credit facility for certain working capital and capital expenditure needs for its subsidiary in Argentina (“Argentina Credit Facility”). As of September 30, 2023, we had $1.9 million outstanding and availability of $0.1 million under the Argentina Credit Agreement. Borrowings bear interest at a rate of 2.50% per annum. The Argentina Credit Facility was backed by a letter of credit under our ABL Credit Agreement, and expired and was repaid in October 2023.

Swedish Credit Facility

In January 2022, the Company entered into a revolving credit facility for seasonal working capital needs of subsidiaries in Sweden (“Swedish Credit Facility”). As of September 30, 2023, we had a nominal amount outstanding and availability of approximately $4.6 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 expires on December 31, 2023 and the Company intends to renew it annually.

Finland Credit Agreement

In January 2022, the Company also entered into an agreement guaranteed by certain accounts receivable and inventory in Finland (“Finland Credit Agreement”). As of September 30, 2023, there were $1.4 million of letters of credit outstanding against the Finland Credit Agreement. The Finland Credit Agreement expires on January 31, 2024 and the Company intends to renew it annually.

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 September 30, 2023, we are in compliance with all covenants under the credit agreements.

NOTE 7 – COMMITMENTS AND CONTINGENCIES

Litigation

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.

There have been no other material developments in our legal proceedings during the quarter ended September 30, 2023. For additional discussion of our legal proceedings, please see our 2022 Annual Report and Quarterly Report on Form 10-Q for the quarter ended June 30, 2023.

Product Purchase Obligations

In the normal course of our Completion Fluids & Products Division 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 September 30, 2023, the aggregate amount of the fixed and determinable portion of the purchase obligation pursuant to our Completion Fluids & Products Division’s supply agreements was approximately $74.9 million, including $4.0 million for the remainder of 2023, $24.0 million in 2024, $21.9 million in 2025, $15.6 million in 2026, $7.1 million in 2027, and $2.3 million thereafter, extending through 2028.

NOTE 8 – FAIR VALUE MEASUREMENTS

Financial Instruments

Investments

We retained an interest in CSI Compressco representing approximately 3.7% of CSI Compressco’s outstanding common units as of September 30, 2023. In December 2021, we invested in a $5.0 million convertible note issued by CarbonFree. In addition, we receive cash and stock of Standard Lithium under the terms of our arrangements as noted in Note 5 - “Investments.”

Our investments in CSI Compressco and Standard Lithium are recorded in investments on our consolidated balance sheets based on the quoted market stock price (Level 1 fair value measurements). The stock component of consideration received from Standard Lithium 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. Changes in the value of stock are recorded in other (income) expense, net in our consolidated statements of operations.

Our investment in convertible notes issued by CarbonFree is recorded in our consolidated financial statements based on an internal valuation with assistance from a third-party valuation specialist (Level 3 fair value measurement). The valuation is impacted by key assumptions, including the assumed probability and timing of potential debt or equity offerings. The convertible note includes an option to convert the note into equity interests issued by CarbonFree. The change in the fair value of the embedded option is 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. The change in our investment in CarbonFree for the nine-month period ended September 30, 2023 is as follows:

	Nine Months Ended September 30, 2023

Impairments

During the second quarter of 2023, 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, including the rent rate per square foot (a Level 3 fair value measurement) in accordance with the fair value hierarchy.

Other

The fair values of cash, restricted cash, accounts receivable, accounts payable, accrued liabilities, short-term borrowings and long-term debt pursuant to our Term Credit Agreement, ABL Credit Agreement, Argentina Credit Agreement, and Swedish Credit Agreement approximate their carrying amounts. See Note 6 - “Long-Term Debt and Other Borrowings” for further discussion.

NOTE 9 – NET INCOME PER SHARE

The following is a reconciliation of the weighted average number of common shares outstanding with the number of shares used in the computations of net income per common and common equivalent share:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2023	2022	2023	2022
	(in thousands)
Number of weighted average common shares outstanding	129,777	128,407	129,395	127,890

Average diluted shares outstanding	132,089	128,407	130,835	129,704

The average diluted shares outstanding excludes the impact of certain outstanding equity awards of 1.5 million shares for the three-month period ended September 30, 2022 as the inclusion of these shares would have been anti-dilutive due to the net loss from continuing operations recorded during this period.

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

The following discussion and analysis of financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and accompanying notes included in this Quarterly Report. In addition, the following discussion and analysis should also be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) on February 27, 2023 (“2022 Annual Report”). This discussion includes forward-looking statements that involve certain risks and uncertainties.

Business Overview

We are an energy services and solutions company operating on six continents, focused on calcium chloride, completion fluids and associated products and services, comprehensive water management solutions, frac flowback, and production well testing. Calcium chloride is used in the oil and gas industry, and also has broad industrial applications to the agricultural, road, food and beverage and lithium production markets. We are composed of two segments – Completion Fluids & Products Division and Water & Flowback Services Division.

Consolidated revenue for the first nine months of 2023 of $473.1 million reflects a 16.6% increase over the prior year, reflecting growth in international markets and the Gulf of Mexico, as well as a strong second quarter for our Northern Europe industrial chemicals business. Our strong results for the first nine months of 2023 reflect our employees delivering operational and financial excellence in our core businesses while simultaneously advancing our key strategic initiatives. Third-quarter consolidated revenue of $151.5 million reflects a 13.7% decrease following the strong Northern European industrial chemical business seasonal peak in the second quarter.

Completion Fluids & Products Division revenues for the first nine months of 2023 increased 16.1% compared to 2022 as pricing and market share have continued to improve. Completion Fluids & Products Division revenues decreased 25% sequentially, following a new segment record high during the second quarter, including the seasonal peak for our Northern Europe industrial chemicals business. Our offshore results declined compared to the second quarter as projects were completed or shifted into the fourth quarter.

Our Water & Flowback Services revenues remained stable compared to the second quarter of 2023 and improved slightly compared to the prior year, driven primarily by the first two early production facilities in Latin America that became operational in the third quarter of 2022 and the third early production facility which became operational in May 2023. Our growing fleet of TETRA SandStormTM advanced cyclone technology separators also remains at high utilization with continued market penetration and positive pricing progression. Water & Flowback Services margins have continued to improve, reflecting ongoing automation and cost-reduction initiatives.

We are committed to pursuing low-carbon energy initiatives that leverage our fluids and aqueous chemistry core competencies, our significant bromine and lithium assets and technologies, and our leading calcium chloride production capabilities. In June 2023, we entered into a memorandum of understanding (“MOU”) with Saltwerx LLC (“Saltwerx”), an indirect wholly owned subsidiary of a Fortune 500 company, 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. We filed an amended brine unit application (the “Application”) covering approximately 6,138 acres, which expands the size of the unit area and also combines brine acreage that was previously leased by each of TETRA and Saltwerx (the “Brine Unit”), with the Arkansas Oil & Gas Commission (“AOGC”). On September 26, 2023, the AOGC held a public hearing and unanimously approved our application to establish the Brine Unit. We completed the evaluation of results from the second exploratory well on our acreage in Arkansas in the third quarter with exceptional results. These results are being used to update the lithium and bromine resource report which we plan to complete and release in the fourth quarter. Additional steps are required before making a decision to develop the bromine assets and include further studies to analyze the resource as well as completion of a pre-feasibility and/or feasibility study.

Consolidated revenues decreased between the current and previous quarters primarily due to a decrease in overall activity for the Completion Fluids & Products division sales volume from the strong Northern European industrial chemical seasonality impact each year on our results in the second quarter. See Divisional Comparisons section below for a more detailed discussion of the change in our revenues.

Consolidated gross profit as a percentage of revenue decreased primarily due to our Completion Fluids & Products division lower overall activity levels and margins. See Divisional Comparisons section below for additional discussion.

Consolidated exploration and pre-development costs increased primarily due to costs associated with the lithium front-end engineering and design study and appraisal costs for the second exploratory brine well in Arkansas.

Consolidated general and administrative expenses decreased compared to the prior quarter, primarily due to a $1.3 million decrease in provision for credit losses as a provision established in the second quarter was reversed in the third quarter following improved collections, a $0.4 million decrease in general expenses and a $0.3 million decrease in legal expenses.

Consolidated other income, net, decreased in the current quarter, compared to the prior quarter primarily due to the $2.8 million decrease in credits for exploration and pre-development costs reimbursable from Saltwerx following the cumulative credit in the second quarter, and a $2.0 million increase in unrealized losses from our

21

Standard Lithium shares received in April 2022 and 2023, partially offset by a $0.5 million increase in unrealized gain due to the change in the unit price of the CSI Compressco common units we own.

Consolidated provision for income tax was $1.2 million during the current quarter, compared to a $2.9 million provision during the prior quarter. Our consolidated effective tax rate for the three months ended September 30, 2023 was 18.6% due to income generated during the quarter, partially offset by the utilization of net operating loss carryforwards in the United States and certain other non-U.S. jurisdictions for which a valuation allowance had been established. 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. Included in our deferred tax assets are net operating loss carryforwards and tax credits that are available to offset future income tax liabilities in the United States and certain other non-U.S. jurisdictions.

Revenues for our Completion Fluids & Products Division decreased primarily due to decreased volumes for industrial chemical sales following the seasonal uplift in Northern Europe in the prior quarter, as well as timing of customer completion schedules, which resulted in some planned offshore activity pushing from the third to the fourth quarter.

Gross profit for our Completion Fluids & Products Division decreased compared to the prior quarter primarily due to the decline in revenues mentioned above. Our profitability in future periods will continue to be affected by the mix of our products and services, market demand for our products and services, and drilling and completions activity.

Completion Fluids & Products Division exploration and pre-development costs associated with our potential Southwest Arkansas bromine development project increased $1.4 million due to costs associated with the lithium front-end engineering and design study and well appraisal costs. General and administrative expense for the division decreased $2.7 million, primarily due to a $1.3 million decrease in provision for credit losses as a provision established in the second quarter was reversed in the third quarter following improved collections, and a $1.3 million decrease in short-term incentive compensation expense. Other income, net decreased primarily due to the $2.8 million decrease in credits for exploration and pre-development costs from Saltwerx following the cumulative credit in the second quarter, and a $2.0 million increase in unrealized losses from our investment in Standard Lithium shares due to a decline in the share price.

Revenues for our Water & Flowback Services Division in the current quarter increased due to continued higher revenues from our early production facilities in Latin America following completion of the third facility in May 2023. The North America onshore business revenue was relatively flat compared to the prior quarter.

Gross profit for our Water & Flowback Services Division remained comparable to the previous quarter. Gross profit as a percentage of revenue also remained comparable reflecting the ongoing margin expansion efforts driven by investments in technology, integration, digitalization and the benefit of our early production facilities in Argentina. While we have seen some signs of softness in certain land segments in the United States, pricing has remained relatively stable for our differentiated products and service offerings.

The Water & Flowback Services Division income before taxes and discontinued operations increased primarily due to a $0.6 million decrease in general and administrative expense primarily due to cost reduction initiatives, partially offset by a $0.2 million increase in interest expense due to borrowings under the Argentina Credit Agreement.

 (1) Percent change is not meaningful

Consolidated revenues increased in the current year primarily due to improving industry conditions compared to the prior year for both our Completion Fluids & Products and Water & Flowback Services divisions, as well as the first two early production facilities in Argentina that commenced operations in the third quarter of 2022 and a third early production facility that became operational in the second quarter of 2023. See Divisional Comparisons section below for a more detailed discussion of the change in our revenues.

Consolidated gross profit increased in the current year primarily due to the increase in revenue, partially offset by an increase in costs associated with the higher Water & Flowback Services division activity levels described above. Profit margins for both divisions also improved due to stronger market conditions, a shift to higher-margin projects as well as price improvements and cost reduction initiatives.

Consolidated exploration and pre-development costs increased $3.3 million compared to the prior year primarily due to costs associated with the lithium front-end engineering and design study and drilling and appraisal costs associated with our second exploratory brine well in Arkansas.

Consolidated general and administrative expenses increased compared to the prior year, primarily due to $5.4 million of increased wage and benefit-related expenses driven by divisional headcount additions and higher operational activity levels, as well as higher short and long-term incentive expense, including the impact of the increase in our stock price on long-term incentive awards.

Consolidated interest expense, net, increased in the current year primarily due to an increase in the interest rate on our Term Credit Agreement and increased interest on borrowings under our ABL Credit Agreement and Argentina Credit Agreement.

Consolidated other income, net, increased in the current year, compared to the prior year primarily due to $6.7 million credits for exploration and pre-development costs reimbursable from Saltwerx under the MOU entered in in June 2023, offset by a $3.0 million decrease in foreign exchange gains.

24

Consolidated provision for income taxes was $5.6 million during the current year, compared to $2.9 million during the prior year. Our consolidated effective tax rate for the current year was 15.9%, compared to 23.5% during the prior year. The increase in our tax provision compared to the prior year was primarily due to the increase in income, while our effective tax rate decreased because a significant portion of the increase in income was in jurisdictions for which we were able to utilize net operating losses for which we had established valuation allowances. 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. Included in our deferred tax assets are net operating loss carryforwards and tax credits that are available to offset future income tax liabilities in the United States as well as in certain non-U.S. jurisdictions.

Revenues for our Completion Fluids & Products Division increased compared to the prior year primarily due to higher European industrial chemical sales volumes, as well as favorable pricing and customer mix. The division also benefited from recent capacity expansions following investments in Brazil, the Gulf of Mexico and the United Kingdom.

Gross profit for our Completion Fluids & Products Division increased compared to the prior year due to an increase in revenues. Gross profit as a percentage of revenue for our Completion Fluids & Products division increased primarily due to favorable pricing improvements. Our profitability in future periods will continue to be affected by the mix of our products and services, market demand for our products and services, and drilling and completions activity.

Income before taxes and discontinued operations for our Completion Fluids & Products Division increased compared to the prior year driven by higher gross profit, $6.7 million of credits for exploration and pre-development costs reimbursable from Saltwerx as well as a $0.4 million decrease in unrealized losses from our investment in Standard Lithium shares, both included in other income, net. These increases were partially offset by a $3.3 million increase in costs associated with the exploratory brine project compared to the prior year; a $3.0 million increase in general and administrative costs due to higher compensation and short-term incentive expense due to increased activity levels and strong results; and a $0.8 million decrease in unrealized gains from the change in fair value of the CarbonFree convertible note embedded option.

Revenues for our Water & Flowback Services Division increased significantly for both water management and production testing due to overall higher customer drilling and completion activity. Customer activity levels have continued to improve, primarily in our North America land business. Revenues have also increased in Latin America due to two early production facilities that began operations in the third quarter of 2022 and a third early production facility that became operational in the second quarter of 2023.

Gross profit for our Water & Flowback Services Division improved substantially from the prior year primarily due to higher revenues resulting from the increased activity levels described above and pricing improvements, and a shift to higher margin projects as well as continuous efforts to increase margins through streamlining operations and automation.

Income before taxes and discontinued operations for our Water & Flowback Services Division increased in the current year primarily due to an improvement in the gross profit described above and a $1.2 million decrease in general and administrative expense from cost reduction initiatives, partially offset by a $1.6 million decrease in foreign exchange gains and a $0.7 million decrease in gains on asset sales.

Non-GAAP Financial Measures

We use U.S. GAAP financial measures such as revenues, gross profit, income (loss) before taxes and discontinued operations, and net cash provided by operating activities, as well as certain non-GAAP financial measures, including Adjusted EBITDA, as performance measures for our business.

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) before taxes and discontinued operations, excluding impairments, exploration and pre-development costs, certain special, non-recurring or other charges (or credits), interest, depreciation and amortization, income from collaborative arrangement and certain non-cash items such as equity-based compensation expense. The most directly comparable GAAP financial measure is net income (loss) before taxes and discontinued operations. Exploration and pre-development costs represent expenditures incurred to evaluate potential future development of TETRA’s lithium and bromine properties in Arkansas. Such costs include exploratory drilling and associated engineering studies. Income from collaborative arrangement represents the portion of exploration and pre-development costs that are reimbursable by our strategic partner. Exploration and pre-development costs and the associated income from collaborative arrangement are excluded from Adjusted EBITDA because they do not relate to the Company’s current business operations. Adjustments to long-term incentives represent adjustments to valuation of long-term cash incentive compensation awards that are related to prior years. These costs are excluded from Adjusted EBITDA because they do not relate to the current year and are considered to be outside of normal operations. Long-term incentives are earned over a three-year period and the costs are recorded over the three-year period they are earned. The amounts accrued or incurred are based on a cumulative of the three-year period. Equity-based compensation expense represents compensation that has been or will be paid in equity and is excluded from Adjusted EBITDA because it is a non-cash item.

Adjusted EBITDA is used by management as a supplemental financial measure to assess financial performance, without regard to charges or credits that are considered by management to be outside of its normal operations and without regard to financing methods, capital structure or historical cost basis, and to assess the Company’s ability to incur and service debt and fund capital expenditures.

Adjusted EBITDA is a financial measure that is not in accordance with U.S. GAAP and should not be considered an alternative to net income, operating income, cash provided by operating activities, or any other measure of financial performance presented in accordance with U.S. GAAP. This measure may not be comparable to similarly titled financial metrics of other companies, as other companies may not calculate Adjusted EBITDA in the same manner as we do. Management compensates for the limitations of Adjusted EBITDA as an analytical tool by reviewing the comparable U.S. GAAP measures, understanding the differences between the measures, and incorporating this knowledge into management’s decision-making processes.

Liquidity and Capital Resources

We believe that our capital structure allows us to meet our financial obligations. Our liquidity at the end of the third quarter was $107.0 million. Liquidity is defined as unrestricted cash plus availability under the ABL Credit Agreement, Argentina Credit Facility, and Swedish Credit Facility. Information about the terms and covenants of our debt agreements can be found in Note 6 - Long Term Debt and Other Borrowings.

Our consolidated sources and uses of cash are as follows:

	Nine Months Ended September 30,
	2023		2022
	(in thousands)
Operating activities	$	51,331	$	25,948
Investing activities	(28,918)		(28,280)
Financing activities	(1,894)		(2,771)

Operating Activities

Consolidated cash flows provided by operating activities increased compared to the first nine months of 2022 primarily due to an increase in cash profit and working capital changes.

Investing Activities

Total cash capital expenditures during the first nine months of 2023 were $30.2 million, which reflects increased expenditures to accommodate industry-wide activity recoveries. Our Water & Flowback Services Division spent $22.0 million on capital expenditures, primarily to deploy additional SandStorm units to meet increased demands and to maintain, automate and upgrade its water management and flowback equipment fleet. Water and Flowback Services Division capital expenditures also included expenditures related to construction of the third early production facility in Argentina. Our Completion Fluids & Products Division spent $7.8 million on capital expenditures, primarily investing in additional capacity to support higher projected activity levels in the United States, Latin America and Europe.

Investing activities during the first nine months of 2023 and 2022 included $2.9 million and $3.8 million, respectively, of proceeds for insurance settlements from damage to our Lake Charles facility in 2020.

Historically, a significant majority of our planned capital expenditures have been related to identified opportunities to grow and expand our existing businesses. We are also focused on enhancing shareholder value by capitalizing on our key mineral assets, brine mineral extraction expertise, and deep chemistry competency to expand our offerings into the low carbon energy markets. However, we continue to review all capital expenditure plans carefully in an effort to conserve cash. We currently have no long-term capital expenditure commitments. If the forecasted demand for our products and services increases or decreases, the amount of planned expenditures on growth and expansion may be adjusted.

Lithium and Bromine Inferred Resources

We have rights to the brine underlying our approximately 40,000 gross acres of brine leases in the Smackover Formation in Southwest Arkansas, including rights to the bromine and lithium contained in the brine. With respect to approximately 35,000 acres of that total acreage, we granted Standard Lithium an option to acquire the lithium rights. Standard Lithium delivered a notice to exercise this option to acquire those lithium rights on October 6, 2023. The agreements governing this option contemplate a 2.5% royalty that Standard Lithium would pay us based on gross lithium revenues. A copy of the Option Agreement with certain confidential information redacted is filed as Exhibit 10.1 to this Quarterly Report. Additional information on these inferred resources is described in Part I, “Item 2. Properties” in our 2022 Annual Report.

During early 2023, we completed an initial economic assessment for a bromine extraction plant. We expect an initial economic assessment to follow in early 2024 for a lithium extraction plant, subject to the progress of early engineering. In June 2023, we entered into the MOU with Saltwerx, an indirect wholly owned subsidiary of a Fortune 500 company, 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. We filed an amended Application covering approximately 6,138 acres, which expands the size of the unit area and also combines brine acreage that was previously leased by each of TETRA and Saltwerx, with the AOGC. On September 26, 2023, the AOGC held a public hearing and unanimously approved our application to establish the Brine Unit. On October 17, 2023, the AOGC issued formal orders establishing the Brine Unit and integrating all unleased parties within the Brine Unit, subject to a 60-day statutory election period for each unleased party to elect whether or not to participate and share in costs of development of the Brine Unit. If no such election is made within the election period, such unleased parties will be deemed integrated within the Brine Unit as described in the formal orders. The Brine Unit will cover approximately 6,138 acres combining brine acreage leased by each of us and Saltwerx for development. Under Arkansas law, while bromine can be commercially extracted, the AOGC will need to establish the applicable lithium royalty before we can commercially produce lithium from the Brine Unit.

The MOU includes provisions relating to: (i) initial brine ownership percentages within the Brine Unit, including the bromine and lithium contained in the brine, (ii) the transfer of certain leased acres outside the proposed Brine Unit from us to Saltwerx after the expiration of the 60-day statutory election period, (iii) Saltwerx reimbursing us for certain expenses incurred by us to date regarding the development of leased acreage to be included in the Brine Unit, and (vi) an allocation of certain future 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 second quarter of 2023, we also contracted a third-party firm to execute a front-end engineering and design study for a lithium production facility. Only upon completion of an indicated resources study, pre-feasibility and/or feasibility study and attainment of capital commitment from either a joint venture partner, governments grants or loans, or other cost-effective sources of capital that will not over-lever the Company, in addition to confirmation of a successful recapitalization of the long-duration zinc-bromide battery storage manufacturers, would we proceed to a final investment decision.

Financing Activities

Our financing activities for the first nine months of 2023 include $97.4 million of borrowings and $98.4 million of repayments under the ABL Credit Agreement, Argentina Credit Facility and Swedish Credit Facility, as well as $0.8 million of capital lease payments associated with equipment leased primarily for the early production facilities in Argentina. We may supplement our existing cash balances and cash flow from operating activities with short-term borrowings, long-term borrowings, issuances of equity and debt securities, and other sources of capital. We are aggressively managing our working capital and capital expenditure needs in order to maximize our liquidity in the current environment.

Long-Term Debt

Term Credit Agreement.    The Term Credit Agreement is scheduled to mature on September 10, 2025. As of September 30, 2023, $163.1 million in aggregate principal amount of our Term Credit Agreement is outstanding. 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. If our Leverage Ratio at year-end is less than 1.50 to 1.00, then no prepayment is required.

Asset-Based Credit Agreement. As of September 30, 2023, our ABL Credit Agreement provides for a senior secured revolving credit facility of up to $80.0 million, with a $20.0 million accordion. The credit facility is subject to a borrowing base to be determined by reference to the value of inventory and accounts receivable, and includes a sublimit of $20.0 million for letters of credit, a swingline loan sublimit of $11.5 million, and a $15.0 million sub-facility subject to a borrowing base consisting of certain trade receivables and inventory in the United Kingdom. The amounts we may borrow under the ABL Credit Agreement are derived from our accounts receivable, certain accrued receivables and certain inventory. Changes in demand for our products and services have an impact on our eligible accounts receivable, accrued receivables and the value of our inventory, which could result in significant changes to our borrowing base and therefore our availability under our ABL Credit Agreement. As of September 30, 2023, we had no balance outstanding and $11.5 million in letters of credit and guarantees against our ABL Credit Agreement and availability of $68.5 million, subject to compliance with the covenants, borrowing base, and other provisions of the ABL Credit Agreement.

Argentina Credit Facility. In January 2023, the Company entered into a revolving credit facility for certain working capital and capital expenditure needs for its subsidiary in Argentina (“Argentina Credit Facility”). As of September 30, 2023, we had $1.9 million outstanding and availability of $0.1 million under the Argentina Credit Agreement. Borrowings bear interest at a rate of 2.50% per annum. The Argentina Credit Facility was backed by a letter of credit under our ABL Credit Agreement, and expired and was repaid in October 2023.

Swedish Credit Facility. In January 2022, the Company entered into a revolving credit facility for seasonal working capital needs of subsidiaries in Sweden. As of September 30, 2023, we had a nominal amount outstanding and availability of approximately $4.6 million under this agreement. 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 expires on December 31, 2023 and the Company intends to renew it annually.

Finland Credit Agreement. In January 2022, the Company also entered into a credit agreement guaranteed by certain accounts receivable and inventory in Finland (“Finland Credit Agreement”). As of September 30, 2023, there were $1.4 million of letters of credit outstanding against the Finland Credit Agreement. The Finland Credit Agreement expires on January 31, 2024 and the Company intends to renew it annually.

Other Sources and Uses of Cash

In addition to the aforementioned credit facilities, we fund our short-term liquidity requirements from cash generated by our operations and from short-term vendor financing. In addition, as of September 30, 2023, the market value of our investments in CSI Compressco and Standard Lithium were $7.2 million and $2.3 million, respectively, with no holding restrictions on our ability to monetize our interests. In addition, we are party to agreements in which Standard Lithium has the right to explore for, and an option to acquire the right to produce and extract lithium in our Arkansas leases as well as additional potential resources, in the Mojave region of California. Standard Lithium exercised its option with respect to our Arkansas leases on October 6, 2023. We also hold an investment in a convertible note issued by CarbonFree valued at $6.6 million as of September 30, 2023.

On May 5, 2022, we filed a universal shelf Registration Statement on Form S-3 with the SEC. On May 17, 2022, the Registration Statement on Form S-3 was declared effective by the SEC. Pursuant to this registration statement, we have the ability to sell debt or equity securities in one or more public offerings up to an aggregate public offering price of $400 million. This shelf registration statement currently provides us additional flexibility with regards to potential financing that we may undertake when market conditions permit or our financial condition may require.

31

Should additional capital be required, the ability to raise such capital through the issuance of additional debt or equity securities may currently be limited. Instability or volatility in the capital markets at the times we need to access capital may affect the cost of capital and the ability to raise capital for an indeterminable length of time. If it is necessary to issue additional equity to fund our capital needs, additional dilution of our common stockholders will occur. We periodically evaluate engaging in strategic transactions and may consider divesting non-core assets where our evaluation suggests such transactions are in the best interest of our business. In challenging economic environments, we may experience increased delays and failures by customers to pay our invoices. If our customers delay paying or fail to pay us a significant amount of our outstanding receivables, it could have an adverse effect on our liquidity. An increase in unpaid aged receivables would also negatively affect our borrowing availability under the ABL Credit Agreement.

As of September 30, 2023, we had no “off balance sheet arrangements” that may have a current or future material effect on our consolidated financial condition or results of operations.

Critical Accounting Policies and Estimates

    There have been no material changes or developments in the evaluation of the accounting estimates and

the underlying assumptions or methodologies pertaining to our Critical Accounting Policies and Estimates disclosed

in our 2022 Annual Report. In preparing our consolidated financial statements, we make assumptions, estimates, and judgments that affect the amounts reported. These judgments and estimates may change as new events occur, as new information is acquired, and as changes in our operating environments are encountered. Actual results are likely to differ from our current estimates, and those differences may be material.

Cautionary Statement for Purposes of Forward-Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements in this Quarterly Report are identifiable by the use of the following words, the negative of such words, and other similar words: “anticipates”, “assumes”, “believes”, “budgets”, “could”, “estimates”, “expects”, “forecasts”, “goal”, “intends”, “may”, “might”, “plans”, “predicts”, “projects”, “schedules”, “seeks”, “should”, “targets”, “will”, and “would”.

32

These forward-looking statements include statements concerning the inferred mineral resources of lithium and bromine, the potential extraction of lithium and bromine from the leased acreage, the development of the assets including construction of bromine extraction plants, the economic viability thereof, the demand for such resources, and the timing and cost of such activities; the ability to obtain an indicated or measured resources report and an initial economic assessment, indicated or measured resources report, and/or pre-feasibility or feasibility studies regarding our lithium and bromine acreage; statements regarding the Company's beliefs, expectations, plans, goals, future events and performance; and other statements that are not purely historical. With respect to the Company's disclosures of inferred mineral resources, including bromine and lithium carbonate equivalent concentrations, it is uncertain if further exploration will ever result in the estimation of a higher category of mineral resource or a mineral reserve. Inferred mineral resources are considered to have the lowest level of geological confidence of all mineral resources. Investors are cautioned that inferred mineral resources do not have demonstrated economic value. Inferred mineral resources have a high degree of uncertainty as to their existence and as to whether they can be economically or legally commercialized. A significant amount of exploration must be completed in order to determine whether an inferred mineral resource may be upgraded to a higher category. Therefore, investors are cautioned not to assume that all or any part of an inferred mineral resource exists, that it can be economically or legally commercialized, or that it will ever be upgraded to a higher category. With respect to the Company’s disclosures of the MOU with Saltwerx, it is uncertain about the ability of the parties to successfully negotiate one or more definitive agreements, the future relationship between the parties, and the ability to successfully and economically produce lithium and bromine from the Brine Unit.

Management believes that these forward-looking statements are reasonable as and when made. However, investors are cautioned not to place undue reliance on any such forward-looking statements. Such statements speak only as of the date on which they are made, and the Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations, forecasts or projections. These risks and uncertainties include, but are not limited to, those described in Part II, “Item 1A. Risk Factors” and elsewhere in this report and in our 2022 Annual Report, and those described from time to time in our future reports filed with the SEC.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Interest Rate Risk

The interest on our borrowings is subject to market risk exposure related to changes in applicable interest rates. Borrowings under the Term Credit Agreement bear interest at a rate per annum equal to, at the option of TETRA, either (i) SOFR (subject to a 1% floor) plus a margin of 6.25% per annum or (ii) a base rate plus a margin of 5.25% per annum. Borrowings under our ABL Credit Agreement bear interest at an agreed-upon percentage rate spread above SOFR. Borrowings under our Argentina Credit Facility and Swedish Credit Facility bear interest at fixed rates of 2.50% and 2.95%, respectively. The following table sets forth as of September 30, 2023, the principal amount due under our long-term debt obligations and their respective weighted average interest rates. As of September 30, 2023, we had no balance outstanding under our ABL Credit Agreement. We are not a party to an interest rate swap contract or other derivative instrument designed to hedge our exposure to interest rate fluctuation risk.

33

Exchange Rate Risk

We have currency exchange rate risk exposure related to revenues, expenses, operating receivables, and payables denominated in foreign currencies. We may enter into short-term foreign-currency forward derivative contracts 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 expected to be 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. As of September 30, 2023, we did not have any foreign currency exchange contracts outstanding.

Item 4. Controls and Procedures.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2023, the end of the period covered by this quarterly report.

There were no changes in our internal controls over financial reporting that occurred during the quarter ended September 30, 2023, that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings.

For information regarding litigation, see “Item 1. Legal Proceedings” in our 2022 Annual Report, our Quarterly Report on Form 10-Q for the quarter ended June 30, 2023, and Note 7 - “Commitments and Contingencies” in the Notes to Consolidated Financial Statements included in this Quarterly Report.

Item 1A. Risk Factors.

As of the date of this filing, TETRA and its operations continue to be subject to the risk factors previously disclosed in the “Risk Factors” sections contained in our 2022 Annual Report. In addition, we are subject to the following supplemental risk factor.

We may not be able to utilize all or a portion of our net operating loss carryforwards or other tax benefits to offset future taxable income for U.S. federal, state or foreign tax purposes, which could adversely affect our financial position, results of operations and cash flows. We have adopted a Tax Benefits Preservation Plan (the “Tax Plan”) that is designed to protect our Tax Attributes.

As of December 31, 2022, we had United States federal, state, and foreign deferred tax assets associated with net operating loss carryforwards (“NOLs”) equal to approximately $86.2 million, $11.1 million, and $7.8 million, respectively. In those countries and states in which NOLs are subject to an expiration period, our NOLs, if not utilized, will expire at various dates from 2023 through 2042.

We may be limited in the portion of our NOLs that we can use in the future to offset taxable income for United States, federal, state, and foreign income tax purposes. Utilization of these NOLs depends on many factors, including our future taxable income, which cannot be assured.

Under Section 382 (“Section 382”) of the Internal Revenue Code of 1986, as amended (the “Code”), if a corporation experiences an “ownership change,” any NOLs, losses or deductions attributable to a “net unrealized built-in loss” and other tax attributes (“Tax Attributes”) could be substantially limited, and timing of the usage of such Tax Attributes could be substantially delayed. A corporation generally will experience an ownership change 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). Utilization of our Tax Attributes may be subject to a significant annual limitation as a result of prior or future “ownership changes.” Determining the limitations under Section 382 is technical and highly complex, and no assurance can be given that upon further analysis our ability to take advantage of our NOLs or other Tax Attributes may be limited to a greater extent than we currently anticipate.

The Board of Directors has adopted the Tax Plan to protect the availability of the Company’s Tax Attributes. The Tax Plan is designed to reduce the likelihood that we experience an ownership change by deterring certain acquisitions of our common stock. There can be no assurances, however, that the deterrent mechanism will be effective, and, therefore, such acquisitions may still occur. In addition, the Tax Plan could adversely affect the marketability of our common stock by discouraging existing or potential investors from acquiring our common stock or additional shares of our common stock. If the Company is unable to use the Tax Attributes in years in which it has taxable income, the Company will pay significantly more in cash tax than if it were able to utilize the Tax Attributes, and those tax costs would negatively impact the Company’s financial position, results of operations and cash flows.
