NOTE 1 – ORGANIZATION, BASIS OF PRESENTATION, AND SIGNIFICANT ACCOUNTING POLICIES
Organization
We are a geographically diversified oil and gas services company, focused on completion fluids and associated products and services, water management, frac flowback and production well testing. We were incorporated in Delaware in 1981. We are composed of two divisions – 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.
Presentation
Our unaudited consolidated financial statements include the accounts of our wholly owned 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 June 30, 2021 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2021.
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, 2020 and notes thereto included in our Annual Report on Form 10-K, which we filed with the SEC on March 5, 2021.
Significant Accounting Policies
Our significant accounting policies are described in the notes to our consolidated financial statements for the year ended December 31, 2020 included in our Annual Report on Form 10-K. There have been no significant changes in our accounting policies or the application thereof during the second quarter of 2021.
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. For a discussion of the reclassification of the financial presentation of our former Compression Division as discontinued operations, see Note 2 - “Discontinued Operations”. Other than the discontinued operations presentation, the impact of reclassifications was not significant to the prior year's overall presentation. Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate solely to continuing operations and exclude all discontinued operations.
Impairments and Other Charges
Impairments of 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 judgment as to the future undiscounted operating cash flows to be generated from the relevant assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related assets, an impairment is recognized for the excess of the carrying value over fair value. Fair

Table of Contents
value of intangible assets is generally determined using the discounted present value of future cash flows using discount rates commensurate with the risks inherent with the specific assets. Assets held for disposal are recorded at the lower of carrying value or estimated fair value less estimated selling costs. During 2021, we recorded an impairment charge of $0.4 million related to idle equipment in our Canada office within our Water & Flowback Services Division. There were no impairments associated with continuing operations during the six months ended June 30, 2020.
Foreign Currency Translation
We have designated the Euro, the British pound, the Norwegian krone, the Canadian dollar, the Brazilian real, and the Mexican peso as the functional currencies for our operations in Finland and Sweden, the United Kingdom, Norway, 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) and losses are included in other (income) expense, net and totaled $(0.2) million and $(1.0) million during the three and six months ended June 30, 2021, respectively, and $0.8 million and $0.9 million for the three and six months ended June 30, 2020, 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 assets, including our interest in Standard Lithium Ltd. (“Standard Lithium”) and our retained interest in CSI Compressco and liabilities, including the liabilities for the warrants to purchase 11.2 million shares of our common stock (the “Warrants”). 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 in 2021
In December 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 simplifies the accounting for income taxes by eliminating certain exceptions related to intraperiod tax allocation, interim period income tax calculation methodology, and the recognition of deferred tax liabilities for outside basis differences. It also simplifies certain aspects of accounting for franchise taxes and clarifies the accounting for transactions that results in a step-up in the tax basis of goodwill. On January 1, 2021, we adopted ASU 2019-12. The adoption of this standard did not have a material impact on our consolidated financial statements.
Standards not yet adopted
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 currently 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. We are continuing to work through our implementation plan which includes evaluating the impact on our allowance for doubtful accounts methodology, identifying new reporting requirements, and implementing changes to business processes, systems, and controls to support adoption of the standard. Upon adoption, the allowance for doubtful accounts is expected to increase with an offsetting adjustment to retained earnings. Updates at each reporting date after initial adoption will be recorded through selling, general, and administrative expense. ASU 2016-13 has an effective date of the first quarter of fiscal 2023. We continue to assess the potential effects of these changes to 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. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. Entities may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. As of June 30, 2021, we have not modified our credit agreements to remove references to LIBOR. We are currently evaluating the impacts of the provisions of ASU 2020-04 on our consolidated financial statements.

NOTE 2 – DISCONTINUED OPERATIONS
On January 29, 2021, we entered into the Purchase and Sale Agreement with Spartan Energy Partners, LP (“Spartan”) pursuant to which we sold the general partner of CSI Compressco, including the IDRs in CSI Compressco and approximately 23.1% of the outstanding limited partner interests in CSI Compressco, in exchange for the combination of $13.4 million in cash paid at closing, $0.5 million in cash payable on the six-month anniversary of the closing and $3.1 million in contingent consideration in the form of cash and/or CSI Compressco common units if CSI Compressco achieves certain financial targets on or before December 31, 2022. Throughout this Quarterly Report, we refer to the transaction with Spartan as the “GP Sale.” As a result of these transactions, we no longer consolidate CSI Compressco as of January 29, 2021. We recognized a primarily non-cash accounting gain of $120.6 million during the six-month period ended June 30, 2021 related to the GP Sale. The gain is included in income (loss) from discontinued operations, net of taxes in our consolidated statement of operations. We will also continue to provide back-office support to CSI Compressco under a Transition Services Agreement for up to one year until CSI Compressco has completed a full separation from our back-office support functions. Our interest in CSI Compressco and the general partner represented substantially all of our Compression Division.
In addition, 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 Compression and Offshore Divisions are 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 current-year consolidated statement of operations, statement of comprehensive income, statement of equity and statement of cash flows include CSI Compressco activity for January 1 through January 29. Our consolidated statements of cash flows for the six-month periods ended June 30, 2021 and June 30, 2020 included $3.0 million and $11.2 million, respectively, of capital expenditures related to our former Compression division, as well as $271.8 million of proceeds from long-term debt, $273.9 million of payments of long-term debt, $3.6 million from proceeds from sale of property, plant and equipment, and $1.4 million from amortization of deferred financing discounts, costs and gains for the six-month period ended June 30, 2020. Our current-year results do not include CSI Compressco depreciation or amortization as the assets were considered held for sale. A summary of financial information related to our discontinued operations is as follows:

NOTE 3 – REVENUE FROM CONTRACTS WITH CUSTOMERS
Our contract asset balances, primarily associated with customer documentation requirements, were $19.3 million and $12.8 million as of June 30, 2021 and December 31, 2020, 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 $3.0 million and $2.7 million as of June 30, 2021 and December 31, 2020, respectively, and vary based on the timing of invoicing and performance obligations being met. Revenues recognized during the six-month periods ended June 30, 2021 and June 30, 2020 deferred as of the end of the preceding year were not significant. During the six-month periods ended June 30, 2021 and June 30, 2020, contract costs were not significant.

Following the closing of the GP Sale, we continue to own approximately 10.9% of the outstanding CSI Compressco common units. In addition, we are party to agreements in which 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 receives 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. See Note 8 - “Fair Value Measurements” for further information.

As of June 30, 2021, we had no outstanding balance and $6.2 million in letters of credit against our asset-based credit agreement (“ABL Credit Agreement”). Because there was no outstanding balance on this ABL Credit Agreement, associated deferred financing costs of $0.9 million as of June 30, 2021, were classified as other long-term assets on the accompanying consolidated balance sheet. As of June 30, 2021, subject to compliance with the covenants, borrowing base, and other provisions of the ABL Credit Agreement that may limit borrowings, we had an availability of $31.7 million under this agreement. See Note 11 - “Subsequent Events” for additional information.
Our credit agreements contain certain affirmative and negative covenants, including covenants that restrict the ability to pay dividends or other restricted payments. As of June 30, 2021, we are in compliance with all covenants under the credit agreements. Our term credit agreement requires us to offer to prepay a percentage of Excess Cash Flow (as defined in the term credit agreement) following the conclusion of each calendar year. Within five business days of filing our Annual Report for the year ending December 31, 2021, the minimum amount we will be required to offer to prepay pursuant to this obligation is $8.2 million, which is reported as a current liability in our consolidated balance sheet
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 material developments in our legal proceedings during the quarter ended June 30, 2021. For a discussion of our legal proceedings, please see our Annual Report on Form 10-K for the year ended December 31, 2020.

NOTE 8 – FAIR VALUE MEASUREMENTS
Financial Instruments
Investments
Our retained investment in CSI Compressco and our investment in Standard Lithium are recorded based on the quoted market stock price in active markets (a Level 1 fair value measurement). The stock component of consideration received for our arrangement with 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. The unearned income associated with the stock component of this agreement is not significant as of June 30, 2021 or December 31, 2020. Changes in the value of stock are recorded in other income (expense) in our consolidated statements of operations
Warrants
The Warrants are valued using a Black Scholes option valuation model that includes estimates of the volatility of the Warrants (a Level 3 fair value measurement). The Warrants are accounted for as a derivative liability and increases (or decreases) in the fair value of the Warrants are generally associated with increases (or decreases) in the trading price of our common stock and by increases in the volatility of our common stock price, resulting in adjustments to earnings for the associated valuation losses (gains), and resulting in future volatility of our earnings during the period the Warrants are outstanding. The fair value of the Warrants and associated liability increased during the second quarter of 2021 primarily due to the increase in TETRA’s stock price. The estimated volatility as of June 30, 2021 was 60%. The outstanding Warrants expire by December 31, 2021.
Recurring and nonrecurring fair value measurements by valuation hierarchy as of June 30, 2021 and December 31, 2020, are as follows:

NOTE 9 – NET INCOME (LOSS) PER SHARE
The average diluted shares outstanding excludes the impact of certain outstanding equity awards and warrants of 2,013,000 and 1,740,000 shares for the three and six-month periods ended June 30, 2021, respectively, and 16,000 and 11,000 shares for the three and six-month periods ended June 30, 2020, respectively, as the inclusion of these shares would have been anti-dilutive due to the net loss from continuing operations recorded during these periods.

NOTE 11 – SUBSEQUENT EVENTS
On July 30, 2021, we entered into an amendment of the ABL Credit Agreement that, among other things, extended the term of the credit facility to May 31, 2025 and revised our commitment to $80.0 million, with a $20.0 million accordion. The amendment increased the availability by adding the value of accrued Unites States receivables, increased the forward rates on accounts receivable for investment grade customers and incorporated a new $15.0 million sub-facility subject to a borrowing base consisting of certain trade receivables and inventory in the United Kingdom. The amendment resulted in an increase of approximately $9.4 million to the borrowing base as of July 30, 2021, compared to the borrowing base prior to the amendment. In connection with the amendment, we also elected to repay the $8.2 million under our term credit agreement that would have become due in 2022.
In May 2021, we signed a memorandum of understanding (“MOU”) with CarbonFree Chemicals Holdings, LLC (“CarbonFree”), a carbon capture company with patented technologies that capture CO 2 and mineralize emissions to make commercial, carbon-negative chemicals. During the one-year MOU period, both Companies will work towards a definitive agreement that might include investments by TETRA into CarbonFree, a joint venture, or other commercial arrangements. On July 23, 2021, we entered into a commitment to invest $5.0 million in a convertible note to be issued by CarbonFree. Our investment in Carbon Free is contingent on certain conditions and is expected to be completed during the third quarter of 2021.

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 also should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 5, 2021 (“2020 Annual Report”). This discussion includes forward-looking statements that involve certain risks and uncertainties.
Business Overview
We are a geographically diversified oil and gas services company, focused on completion fluids and associated products and services, comprehensive water management, frac flowback and production well testing. We operate through two reporting segments organized into two Divisions - Completion Fluids & Products and Water & Flowback Services. In January, we announced our commitment to pursue low carbon energy initiatives that would leverage our fluids and aqueous chemistry core competencies, our significant bromine and lithium assets (including our approximately 31,100 net acres of brine leases in Arkansas) and technologies, and our leading calcium chloride production capabilities.
After declining to historic lows due to depressed oil prices resulting from Russia and Saudi Arabia’s price war and the COVID-19 pandemic last year, toward the end of 2020 and into the first quarter of 2021, customer activity levels in the North America onshore business began to recover as oil prices returned to over $60 per barrel. Customer activity levels continued to improve during the second quarter as oil prices remained constructive, increasing into the $70 per barrel range by the end of the quarter.
Although activity during the second quarter of 2021 for offshore and international customers remained below prior year levels, our Completion Fluids and Products business delivered higher revenues sequentially compared to the first quarter as activity began to ramp back up in the Gulf of Mexico and internationally. The continued rollout of COVID-19 vaccines and fiscal stimulus policies are expected to support an ongoing global economic recovery and further improve the oil demand outlook which, together with continued discipline from United States operators, should provide support for oil and gas prices and further increases in offshore activity both in the Gulf of Mexico and internationally during the second half of the year. However, the current market conditions resulting from the COVID-19 pandemic could rapidly change and there could be a new outbreak of a COVID-19 variant or the vaccines may not be as effective as anticipated, which could negatively impact the demand for our services and products and our future revenues, results of operations and cash flows.
With activity levels expected to further increase during the second half of the year, we are continuing to tightly manage our cost structure. Many of the cost reduction initiatives executed in response to unprecedented industry conditions last year remained in effect as of the end of the second quarter.
On January 29, 2021 as previously announced in our 2020 Annual Report, we closed the sale of the general partner of CSI Compressco, including incentive distribution rights (“IDRs”) in CSI Compressco and approximately 23.1% of the outstanding limited partner interests in CSI Compressco, referred to as the “GP Sale.” We recorded a book gain of $120.6 million during 2021 in connection with the GP Sale. This gain, most of which was non-cash, was a function of CSI Compressco having a negative carrying value within our consolidated balance sheet due to our share of cumulative losses and distributions. We have reflected the operations of our former Compression Division as discontinued operations for all periods presented. Following the closing of the transaction, we continue to own approximately 10.9% of the outstanding CSI Compressco common units. See Note 2 – “Discontinued Operations” in the Notes to Consolidated Financial Statements for further information.
During the first quarter of 2021, we used proceeds from the GP sale and available cash on hand to pay down $29.3 million on our term loan, which matures in September 2025.

Consolidated revenues increased in the current year quarter primarily due to improving industry conditions compared to the prior year quarter which had been significantly affected by the impact of the COVID-19 pandemic and reduced demand for oil and gas. See Divisional Comparisons section below for a more detailed discussion of the change in our revenue.
Consolidated gross profit increased in the current year quarter primarily due to the increase in revenue, partially offset by an increase in costs associated with the higher activity levels described above, resulting in relatively stable margins.
Consolidated general and administrative expenses decreased for the current quarter compared to the prior year quarter, primarily due to cost reduction actions taken during the last twelve months, including reduced compensation of $2.6 million. In addition, prior year bad debt expense was $3.8 million, which included a significant reserve related to a customer bankruptcy.
Increases (or decreases) in the fair value of the Warrants are generally associated with increases (or decreases) in the trading price of our common stock, resulting in adjustments to earnings for the associated valuation losses (gains), and resulting in future volatility of our earnings during the period the Warrants are outstanding. The increase in TETRA’s stock price over the last three months resulted in the fair-value adjustment expense in the current period of $2.7 million.
Consolidated other income, net, increased in the current quarter, compared to the prior year quarter primarily due to a $1.2 million increase in income related to unit and stock price appreciation of our investments in CSI Compressco and Standard Lithium. In addition, other income, net, includes foreign currency gains of
19

Table of Contents
$0.2 million in the current year quarter compared to foreign currency losses of $0.8 million in the prior year quarter. These increases in other income were partially offset by a $0.6 million decrease in gains associated with the sale of assets.
Consolidated provision for income taxes was $1.4 million during the current quarter, compared to $1.1 million during the prior year quarter. Our consolidated effective tax rate for the current quarter of negative 26.3% was primarily the result of losses generated in entities for which no related tax benefit has been recorded. The losses generated by these entities do not result in tax benefits due to offsetting valuation allowances being recorded against the related net deferred tax assets. 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.
Income from discontinued operations, net of taxes, was nominal compared to a loss of $23.8 million for the prior year quarter. The current period includes a $(0.1) million adjustment to the gain recognized from the GP Sale completed in January 2021, while the prior year reflects CSI Compressco‘s full quarter results, including $9.0 million of asset impairments.
Income (loss) attributable to noncontrolling interest improved $15.7 million from the prior year quarter as CSI Compressco’s results were included in the prior year, while the continuing noncontrolling interest is immaterial for TETRA.

Revenues for our Completion Fluids & Products Division decreased compared to the prior year quarter primarily due to lower offshore activity in the Gulf of Mexico and internationally. The timing of the reduction in offshore activity during 2020 due to the effects of the COVID-19 pandemic lagged onshore and did not significantly impact the prior year quarter for this division.
Completion Fluids & Products Division gross profit for the current year quarter decreased in relation to decreased revenues mentioned above although margins remained relatively stable.
Pretax income for our Completion Fluids & Products Division increased compared to the prior year period driven by a decrease in general and administrative expense and an increase in other income. The decrease in general and administrative expense was a result of decreased bad debt expense of $3.0 million associated with a customer bankruptcy in the prior year, and decreased wage and benefit related expenses of $0.8 million. The increase in other income, net, was primarily due to a $1.1 million increase in income from our investment in Standard Lithium, including an increase in the Standard Lithium stock price as well as income associated with additional shares received in May 2021. Foreign currency fluctuations were favorable compared with the prior year quarter by $0.4 million.

Revenues for our Water & Flowback Services Division increased due to higher customer drilling and completion activity compared to the prior year quarter. Revenues for the prior year quarter had been significantly impacted by industry-wide reductions in rig and frac count resulting from historically low oil prices due to the price war between Russia and Saudi Arabia, as well as the global pandemic.
Gross loss for our Water & Flowback Services Division improved in the current quarter compared to the prior year quarter, primarily due to higher revenues resulting from the increased activity levels described above. Additionally, the decrease in capital expenditures over the past twelve months has resulted in a decrease in depreciation expense as assets become fully depreciated.
The Water & Flowback Services Division reported a lower pretax loss in the current quarter primarily due to an improvement in the gross loss described above, as well as a decrease in general and administrative expense. General and administrative expense for our Water & Flowback Services Division decreased primarily due a decrease in bad debt expense of $0.7 million.

Corporate Overhead pretax loss decreased due to lower general and administrative expense and interest expense, offset by a $2.7 million fair value adjustment for the outstanding Warrants liability in the current quarter resulting primarily from the increase in TETRA’s stock price. General and administrative expense decreased primarily due to lower salary and employee expenses of $1.7 million and reduced professional expenses of $0.7 million. Salary and employee expenses were lower due to staffing reductions, despite continued appreciation in our stock price, which resulted in $1.3 million of additional expense related to certain long-term incentive compensation awards. The increase in TETRA’s stock price over the last twelve months resulted in the Warrants fair-value adjustment expense in the current period of $2.7 million.

Consolidated revenues decreased in the current year period compared to the prior year period primarily due to the effects of the COVID-19 pandemic and the impact of the associated decline in oil prices on customer activity levels. The first quarter of the prior year period was not affected by the decline in oil prices or the pandemic. United States onshore activity was significantly impacted in the second quarter of 2020, but the significant ramp down in offshore and international activity did not occur until the second half of 2020. Gross profit as a percentage of revenue declined primarily due to the impact of fixed costs including rent, depreciation and amortization, which do not vary with revenue, as well as product mix. In addition, our revenues were negatively impacted by historic cold weather during February of 2021, which temporarily shut down operations in several southern states within the United States. See Divisional Comparisons section below for additional discussion.
Consolidated general and administrative expenses decreased primarily due to decreased bad debt expense of $4.7 million and decreased salary and employee expenses of $3.1 million, partially offset by increased professional services fees of $1.2 million related to the GP Sale. Salary and employee expenses were lower despite appreciation in our stock price since the start of the year, which resulted in $4.7 million of additional expense related to certain long-term incentive compensation awards. The decrease in our salary and employee expenses stemmed from our restructuring efforts and headcount reductions in response to the decline in activity levels.
Consolidated interest expense, net, decreased in the current year period primarily due to $29.3 million of repayments of our term credit facility during the first quarter of 2021.
The increase in TETRA’s stock price over the last six months resulted in the Warrants fair-value adjustment expense in the current year period of $3.0 million.
Consolidated other income, net, increased primarily due to a $5.4 million increase in unit and stock price appreciation of our investments in CSI Compressco and Standard Lithium. Additionally, the current year period includes foreign currency gains of $1.0 million, compared with foreign currency losses of $0.9 million in the prior year period.

Our consolidated provision for income taxes for the current year period is primarily attributable to taxes in certain non-U.S. jurisdictions and Texas gross margin taxes. Our consolidated effective tax rate for the six-month period ended June 30, 2021 of negative 9.1% was primarily the result of losses generated in entities for which no related tax benefit has been recorded. The losses generated by these entities do not result in tax benefits due to offsetting valuation allowances being recorded against the related net deferred tax assets. 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.
Income from discontinued operations, net of taxes, was $120.9 million compared to a loss of $37.2 million for the prior year, including $14.3 million of asset impairments. The current year income includes a $120.6 million primarily non-cash accounting gain from the deconsolidation of CSI Compressco. This gain is offset by a $0.01 million tax provision after taking into consideration utilization of net operating loss and credit carryforwards.
Income (loss) attributable to noncontrolling interest improved from a $24.5 million loss in the prior year to $0.3 million of income for the first 29 days of January primarily due to the GP Sale in January 2021, and no depreciation or amortization recognized by TETRA for CSI Compressco in the current year.

Revenues for our Completion Fluids & Products Division decreased primarily due to lower activity in the North Sea and some deferral of activity in the Gulf of Mexico as several projects were delayed into future quarters. In addition, the prior year period benefited from a large international order. The COVID-19 pandemic and associated reduction in oil prices did not have a significant impact on offshore activity until the second half of 2020. In addition, the first quarter of 2020 reflected increased division product sales revenues in the Gulf of Mexico, including product sales associated with a TETRA CS Neptune completion fluid sale, and increased international product sales as well as domestic manufactured products sales.
Gross profit for our Completion Fluids & Products Division decreased compared to the prior year period due to lower revenue and product mix. Completion Fluids & Products Division profitability in future periods will continue to be affected by the mix of its products and services, market demand for our products and services, drilling and completions activity and commodity prices.
Pretax income for our Completion Fluids & Products Division decreased due to the reduction in gross profit described above. General and administrative expense decreased primarily due to a lower bad debt expense of $3.0 million and decreased salary and employee-related expenses of $2.1 million. Other (income) expense, net, improved primarily due to a $2.4 million increase in income from our investment in Standard Lithium, most of which was represented by an increase in the Standard Lithium stock price. In addition, foreign currency fluctuations were favorable compared with the prior year period by $1.4 million.

Revenues for our Water & Flowback Services Division decreased in the current year period compared to the prior year period. Although customer activity levels continued to increase from recent lows in response to an improving commodity price environment, they remained well below the level of the first quarter of 2020. Additionally, the current year was negatively impacted by severe weather that caused extended shut downs in certain locations during the first quarter.
The Water & Flowback Services Division reported a deterioration in gross profit (loss) during the current year period compared to the prior year period primarily due to lower revenues resulting from the decreased activity levels described above. In addition, we have incurred some start-up costs associated with a ramp up in activity levels.
The Water & Flowback Services Division reported a lower pretax loss with the increase in gross loss described above, more than offset by a decrease in general and administrative expense. General and administrative expenses decreased primarily due to decreased salary and benefit related expenses of $2.4 million and a decrease in bad debt expense of $1.7 million.

Corporate Overhead pretax loss increased due to an increase in general and administrative expense and the $3.0 million current period Warrants fair value expense from the increase in TETRA’s stock price, offset by an improvement in other (income) expense, net.
General and administrative expense for our Corporate Overhead for the current year period includes $4.7 million of expense related to certain long-term incentive compensation awards resulting from the significant appreciation in our stock price since the beginning of the year and $1.2 million of transaction expenses related to the GP Sale. Excluding these items, general and administrative expense would have been $16.7 million, or $3.0 million lower than prior year.
Corporate other (income) expense, net changed from $0.4 million expense in the prior year period to $3.1 million income in the current year period. This change was primarily due to a $3.0 million increase in the market value of the CSI Compressco units we continue to own following the closing of the GP Sale.

How we Evaluate Operations
We use U.S. GAAP financial measures such as revenues, gross profit, income (loss) before taxes, 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 view Adjusted EBITDA as one of our primary management tools, and we track it on a monthly basis, both in dollars and as a percentage of revenues (typically compared to the prior month, prior year period, and to budget). We define Adjusted EBITDA as earnings before interest, taxes, depreciation, amortization, impairments and certain other non-cash charges and non-recurring adjustments.
Adjusted EBITDA is used as a supplemental financial measure by our management to:
•evaluate the financial performance of our assets without regard to financing methods, capital structure, or historical cost basis; and
•determine our 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 despite current uncertain operating conditions and financial markets. Our liquidity at the end of second quarter was $82.0 million. Liquidity is defined as unrestricted cash plus availability under the revolving credit facility. Information about the terms and covenants of our debt agreements can be found in our 2020 Annual Report and in Note 6 - Long Term Debt and Other Borrowings.

Table of Contents
Our consolidated sources and uses of cash, which include cash activity from our former Compression Division, for January 2021 prior to the closing of the GP sale and for the six months ended 2020 are as follows:

| Six Months Ended June 30,
| 2021 |  | 2020
| (In Thousands)
Operating activities | $ | 7,607 |  |  | $ | 60,387 |
Investing activities | (10,451) |  |  | (14,063) |
Financing activities | (29,775) |  |  | (6,486) |

Operating Activities
Consolidated cash flows provided by operating activities decreased $52.8 million compared to the first six months of 2020. Current year cash flows provided by operating activities include $0.9 million generated by CSI Compressco in January prior to closing of the GP Sale, compared to $13.4 million during the six-month period ending June 30, 2020. Operating cash flows decreased primarily due to including the results of CSI Compressco for one month during the current year compared to six months during the prior year, as well as a decrease in revenue, and the effect of working capital movements at the end of the quarter, particularly related to growth in accounts receivable. We continue to monitor customer credit risk in the current environment and focus on serving larger capitalized oil and gas operators and national oil companies.
Investing Activities
Total cash capital expenditures during the first six months of 2021 were $12.5 million. Our Water & Flowback Services Division spent $7.9 million on capital expenditures, primarily to maintain, automate and upgrade its water management and flowback equipment fleet. Our Completion Fluids & Products Division spent $1.5 million on capital expenditures. Our former Compression Division spent $3.0 million in January of 2021 primarily to maintain its compression fleet.
Historically, a significant majority of our planned capital expenditures have been related to identified opportunities to grow and expand our existing businesses. However, such expenditures have recently been, and may continue to be, postponed or canceled as we are reviewing all capital expenditure plans carefully in an effort to conserve cash. We currently have no long-term capital expenditure commitments. The deferral of capital projects could affect our ability to expand our operations in the future. If the forecasted demand for our products and services increases or decreases, the amount of planned expenditures on growth and expansion may be adjusted.
Financing Activities
As a result of TETRA’s strong cash flow from operations in 2020 and the proceeds from the GP Sale, during the first six months of 2021, we repaid $29.3 million on our term credit agreement. 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
Asset-Based Credit Agreement. As of June 30, 2021, our ABL Credit Agreement provides for a senior secured revolving credit facility of up to $100.0 million, 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 and a swingline loan sublimit of $10.0 million. The amounts we may borrow under the ABL Credit Agreement are derived from our accounts receivable and certain inventory. Changes in demand for our products and services have an
27

Table of Contents
impact on our eligible accounts receivable 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.
On July 30, 2021, we entered into an amendment of the ABL Credit Agreement that, among other things, extended the term of the credit facility to May 31, 2025 and revised our commitment to $80.0 million with a $20.0 million accordion. The amendment increased the availability by adding the value of accrued United States receivables, increased the forward rates on accounts receivable for investment grade customers and incorporated a new $15.0 million sub-facility subject to a borrowing base consisting of certain trade receivables and inventory in the United Kingdom. The amendment resulted in an approximate $9.4 million increase to the borrowing base as of July 30, 2021, compared to the borrowing base prior to the amendment.
Term Credit Agreement. The term credit agreement is scheduled to mature on September 10, 2025. Our term credit agreement requires us to offer to prepay a percentage of Excess Cash Flow (as defined in the term credit agreement) following the conclusion of each calendar year. Within five business days of filing our Annual Report for the year ending December 31, 2021, the minimum amount we will be required to offer to prepay pursuant to this obligation is $8.2 million. In connection with the July 30, 2021 ABL Credit Agreement amendment, we elected to repay the $8.2 million under our term credit agreement that would have become due in 2022. As of July 30, 2021, $176.1 million in aggregate principal amount of our term credit agreement is outstanding.
Other Sources and Uses
In addition to the aforementioned credit facilities, we fund our respective short-term liquidity requirements from cash generated by our respective operations and from short-term vendor financing. 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 transaction is in the best interest of our business. In challenging economic environments, we may experience increased delays and failures by customers to pay our invoices. Given the nature and significance of the pandemic and disruption in the oil and gas industry, we could experience delayed customer payments and payment defaults associated with customer liquidity issues and bankruptcies. 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 of aged unpaid receivable would also negatively affect our borrowing availability under the ABL Credit Agreement.
Off Balance Sheet Arrangements
As of June 30, 2021, 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 2020 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.

Commitments and Contingencies
Investment
In May 2021, we signed a MOU with CarbonFree, a carbon capture company with patented technologies that capture CO 2 and mineralize emissions to make commercial, carbon-negative chemicals. TETRA and CarbonFree have been jointly sharing and leveraging both Companies' technical resources and expertise as CarbonFree continues to advance their carbon capture mineralization pilot plant, processes, and technologies. During the one-year MOU period, both Companies will work towards a definitive agreement that might include investments by TETRA into CarbonFree, a joint venture, or other commercial arrangements that will leverage each Company's strength to advance this market-leading technology. On July 23, 2021, we entered into a commitment to invest $5.0 million in a convertible note to be issued by CarbonFree. Our investment in Carbon Free is contingent on certain conditions and is expected to be completed during the third quarter of 2021.

Leases
We have operating leases for some of our transportation equipment, office space, warehouse space, operating locations, and machinery and equipment. Our leases have remaining lease terms ranging from 1 to 16 years. Information about the terms and covenants of our lease agreements can be found in our 2020 Annual Report.
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 June 30, 2021, 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 $80.7 million, including $4.8 million for the remainder of 2021, $9.5 million per year from 2022 to 2025 and $37.9 million thereafter, extending through 2029.
