TETRA TECHNOLOGIES, INC. ANNOUNCES BRAZIL DEEPWATER COMPLETION

FLUIDS AWARD AND THIRD QUARTER 2024 FINANCIAL RESULTS

•Third-quarter revenue of $142 million

•GAAP income before taxes and discontinued operations of $7.6 million and EPS from continuing operations of $0.02

•Adjusted EBITDA of $23.5 million and adjusted net income per share of $0.03

•Net cash provided by operating activities of $19.9 million, total adjusted free cash flow of $7.4 million, base business adjusted free cash flow(1) of $16.0 million

THE WOODLANDS, Texas, October 29, 2024 / PR Newswire / - TETRA Technologies, Inc. ("TETRA" or the "Company") (NYSE:TTI) today announced third-quarter 2024 financial results and an increasing deepwater backlog following the award of a deepwater project in Brazil.

Brady Murphy, TETRA President and Chief Executive Officer, stated, "Despite challenging third quarter headwinds with three Gulf of Mexico hurricanes and weaker U.S. onshore activity, cash provided by operating activities of $19.9 million and Adjusted EBITDA of $23.5 million came in consistent with our expectations. Completion Fluids & Products achieved 31.7% Adjusted EBITDA margins, while Water & Flowback Services segment Adjusted EBITDA margins were 14.6%. We generated $16 million of adjusted free cash flow from the base business and total adjusted free cash flow of $7.4 million after investing $8.7 million (net of reimbursements from our Evergreen Unit partner) to advance our bromine project in Arkansas.

We continue to build our backlog of deepwater projects by securing a significant multi-well, multi-year deep water completion fluids contract in Brazil. This is our second significant deepwater Brazil contract in the past three years and establishes us as the high-density offshore completion fluids market leader in Brazil. The third-quarter hurricanes, plus another in early October, have shifted some of our planned Gulf of Mexico deepwater work into early 2025. As a result, we expect a slower fourth quarter, but the Brazil award along with the previously announced three well TETRA CS Neptune fluids Gulf of Mexico project and anticipated material step-up in zinc bromide-based battery electrolyte shipments for energy storage is positioning us for a very strong start to 2025. In anticipation of these projects that are starting in the first quarter of 2025, we are increasing at year-end our bromine-based fluids inventory to capitalize on those opportunities. We have also engaged in discussions with bromine suppliers to

1

expand our access to bromine in 2025 and 2026 to meet those demands that are expected to position TETRA for a strong performance in 2025 and beyond.

We continue to deploy automation technology across all of our water and flowback services, which is even more important in this softer environment, and we are very encouraged with customer adoption. In the third quarter, we set an all-time new record for volumes of produced water recycled for frac re-use and we expect the fourth quarter volumes to materially surpass the third quarter treatment of recycled produced water volumes. Our progress on produced water treatment and desalination for beneficial re-use continues with seven customer non-disclosure agreements ("NDAs") in place and two additional NDAs with major oil and gas operators under negotiation.

It is anticipated that US onshore activity will remain slower throughout the fourth quarter and flattish into 2025, and as a result we initiated a series of cost reduction actions in the third quarter, including a 6.5% reduction in global SG&A headcount, and intend to continue to right size our US onshore operations as needed."

Third-Quarter Results

Third-quarter 2024 revenue of $142 million decreased 6% from the third quarter of 2023 and 18% from the second quarter of 2024 following the traditional seasonal peak of industrial chemical sales in Europe. Third-quarter revenue includes the benefit from the sale of an early production facility ("EPF") expansion in Argentina, that partially offset the weaker onshore activity in the Unites States and lower offshore completions fluids activity, primarily in the Gulf of Mexico and Middle East. Net loss of $3.0 million, inclusive of a $5.8 million charge for decommissioning obligations from discontinued operations and $0.5 million of non-recurring charges, compares to net income of $5.4 million in the third quarter of 2023, inclusive of $3.7 million of non-recurring charges, and to net income of $7.6 million in the second quarter of 2024, inclusive of $1.0 million of non-recurring charges.

Third-quarter cash flow provided by operating activities was $19.9 million and compares to cash provided by operating activities of $14.0 million in the third quarter of 2023 and cash provided by operating activities of $25 million in the second quarter of 2024. Base business adjusted free cash flow was $16.0 million while investments in our Arkansas bromine and lithium projects were $8.7 million, resulting in total adjusted free cash flow of $7.4 million in the third quarter of 2024 and compares to total adjusted free cash flow of $7.1 million in the third quarter of 2023 and $9.4 million in the second quarter of 2024. Working capital at the end of the third quarter was $110 million, a $16.4 million decrease from the prior quarter end. Working capital is defined as current assets, excluding cash and restricted cash, less current liabilities. Marketable equity investments in Kodiak Gas Services ("Kodiak"), Inc. and Standard Lithium Ltd. ("Standard Lithium") totaled $14.4 million as of September 30, 2024.

Completion Fluids & Products third quarter of 2024 Adjusted EBITDA margins were 31.7%, a sequential increase of 280 basis points, despite revenue decreasing year-on-year by 11% and decreasing sequentially by 35% following the strong seasonal European industrial chemicals volumes. Overall completion fluids activity was lower in the quarter relative to the second quarter as multiple hurricanes impacted the timing of deepwater projects, resulting in sequentially lower volumes in the Gulf of Mexico as well as lower sales to a major Middle East national oil customer as we transition from a term ending contract to a new two-year fluids award that will start in 2025.

Additionally, we now anticipate the first of three TETRA CS Neptune fluids wells to start in the first quarter of 2025. Net income before taxes for the quarter was $19.1 million (29.4% of revenue) and compares to $26.7 million (26.6% of revenue) in the second quarter of 2024. Adjusted EBITDA was $20.6 million and compares to $28.9 million (28.9% of revenue) in the second quarter of 2024.

Water & Flowback Services revenue of $77 million improved $4.7 million or 6.5% sequentially, with Adjusted EBITDA margins of 14.6%. Water & Flowback Services income before taxes for the quarter was $4.7 million and compares to $3.2 million in the second quarter of 2024. Adjusted EBITDA of $11.2 million increased $0.3 million sequentially. Weaker US onshore completion activity was offset by the sale of the expansion to one of the three Argentina EPFs and a record volume of produced water recycle for frac re-use. As we deploy a larger percentage of our automation technology throughout 2025, we anticipate overall lower field headcount levels which is expected to allow us to maintain or further improve our mid-teens Adjusted EBITDA margins.

During the quarter, we completed an equity investment in KMX Technologies for treating produced water from oil and gas wells for beneficial re-use. The extensive testing of the KMX vacuum membrane technology ("VMD") and the Hyrec Holdings Company W.L.L. osmotic assisted reverse osmosis ("OARO") technology, along with our proprietary pre-treatment technology and know-how, is meeting the challenge to address all variabilities of produced water as an effective industry solution. In addition to the benefits TETRA brings as a service provider, we are taking a minority equity position in KMX that affords TETRA shareholders an opportunity to also benefit from the value creation we will bring to KMX as we commercialize this revolutionary technology.

(1) Base business adjusted free cash flow is defined as total adjusted free cash flow prior to TETRA's investments in the Arkansas bromine and lithium projects.

This press release includes the following financial measures that are not presented in accordance with generally accepted accounting principles in the United States ("GAAP"): Adjusted net income per share, Adjusted EBITDA, and Adjusted EBITDA Margin (Adjusted EBITDA as a percent of revenue) on consolidated and segment basis, adjusted net income, total adjusted free cash flow, base business adjusted free cash flow, net debt, net leverage ratio and return on net capital employed. Please see Schedules E through J for reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures.

Strategic Initiatives Update

Brady Murphy stated, "We invested $8.7 million during the quarter on our strategic initiatives in Arkansas, net of reimbursement from our Evergreen Unit partner, to advance engineering and reservoir studies and began laying the groundwork to put in place power infrastructure for our bromine project. We published a definitive feasibility study in August with compelling economics for the production of bromine from our Evergreen Unit to meet the growing demand for oil and gas offshore completion fluids and the new market for the TETRA PureFlow+ electrolyte in the long duration energy storage market. The zinc bromide electrolyte demand is expected to grow materially beginning in 2025.

We are prioritizing our strategic initiatives on projects that can immediately impact our near-term results, with a focus on TETRA CS Neptune fluids in the Gulf of Mexico, TETRA PureFlow+ electrolyte shipments to Eos Energy Enterprises, and further advancing our water desalination commercial pilot units that are expected to subsequently transition into long duration contracts for commercial desalination plants. Long term we believe that lithium prices will rebound to levels that support increased investment in supply, especially from the U.S., and we and our Evergreen Unit partner remain focused on completing all the engineering studies required to define the lithium project economics."

Schedule D: Statement Regarding Use of Non-GAAP Financial Measures

In addition to financial results determined in accordance with U.S. GAAP, this press release may include the following non-GAAP financial measures for the Company: adjusted net income per share, consolidated and segment Adjusted EBITDA, segment Adjusted EBITDA as a percent of revenue ("Adjusted EBITDA margin"), adjusted net income, total adjusted free cash flow, base business adjusted free cash flow, net debt, net leverage ratio, and return on net capital employed. The following schedules provide reconciliations of these non-GAAP financial measures to their most directly comparable U.S. GAAP measures. The non-GAAP financial measures should be considered in addition to, not as a substitute for, financial measures prepared in accordance with U.S. GAAP, as more fully discussed in the Company's financial statements and filings with the Securities and Exchange Commission.

Management believes that the exclusion of the special charges and credits from the historical results of operations enables management to evaluate more effectively the Company's operations over the prior periods and to identify operating trends that could be obscured by the excluded items.

Adjusted net income is defined as the Company's income (loss) before noncontrolling interests and discontinued operations, excluding certain special or other charges (or credits), and including noncontrolling interest attributable to continued operations. Adjusted net income 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.

Adjusted net income per share is defined as the Company's diluted net income per share attributable to TETRA stockholders excluding certain special or other charges (or credits). Adjusted net income per share 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.

Adjusted EBITDA is defined 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), including loss on debt extinguishment, 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 Evergreen Unit partner. We began capitalizing exploration and pre-development costs in January 2024 and therefore these costs are only excluded for periods prior to January 1, 2024. Exploration and pre-development costs and the associated income from collaborative arrangement were excluded from Adjusted EBITDA in prior periods because they did not relate to the Company's current business operations. Adjustments to long-term incentives represent cumulative 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

11

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.

Total adjusted free cash flow is defined as cash from operations less capital expenditures net of sales proceeds and cost of equipment sold, less payments on financing lease obligations and including cash distributions to TETRA from investments and cash from sales of investments. Base business adjusted free cash flow is defined as Total adjusted free cash flow excluding TETRA's investments in the Arkansas bromine and lithium projects. Management uses this supplemental financial measure to:

•assess the Company's ability to retire debt;

•evaluate the capacity of the Company to further invest and grow; and

•to measure the performance of the Company as compared to its peer group.

Total adjusted free cash flow does not necessarily imply residual cash flow available for discretionary expenditures, as they exclude cash requirements for debt service or other non-discretionary expenditures that are not deducted.

Net debt is defined as the sum of the carrying value of long-term and short-term debt on its consolidated balance sheet, less cash, excluding restricted cash on the balance sheet. Management views net debt as a measure of TETRA's ability to reduce debt, add to cash balances, pay dividends, repurchase stock, and fund investing and financing activities.

Net leverage ratio is defined as debt excluding financing fees & discount on term loan and including letters of credit and guarantees, less cash divided by trailing twelve months adjusted EBITDA for credit facilities. Adjusted EBITDA for credit facilities consists of adjusted EBITDA described above, less non-cash (gain) loss on sale of investments, (gain) loss on sales of assets and excluding certain special or other charges (or credits). Management primarily uses this metric to assess TETRA's ability to borrow, reduce debt, add to cash balances, pay distributions, and fund investing and financing activities.

Return on net capital employed is defined as Adjusted EBIT divided by average net capital employed. Adjusted EBIT is defined as net income (loss) before taxes and discontinued operations, interest, and certain non-cash charges, and non-recurring adjustments. Net capital employed is defined as assets, excluding assets associated with discontinued operations, plus impaired assets, less cash and cash equivalents and restricted cash, and less current liabilities, excluding current liabilities associated with discontinued operations.
