**TETRA TECHNOLOGIES, INC. ANNOUNCES** 

**FOURTH-QUARTER AND STRONG FULL-YEAR 2025 RESULTS**

**AND PROVIDES UPDATE ON STRATEGIC INITIATIVES**

SPRING, Texas, February 25, 2026 / PR Newswire / - TETRA Technologies, Inc. ("TETRA" or the "Company") (NYSE:TTI) announced financial results for the three and twelve months ended December 31, 2025.

**<u>Fourth-Quarter 2025 Financial Highlights</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenues of $146.7 million increased 9% from the fourth quarter of 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Loss from continuing operations was $15.3 million, inclusive of $18.7 million of unusual charges

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Loss per share from continuing operations was $0.11 while Adjusted net income per share was $0.02, excluding unusual charges

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA was $20.4 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net cash provided by operating activities was $31.7 million - materially above the prior sequential quarter and the fourth quarter of 2024;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted free cash flow was $3.1 million and base business adjusted free cash flow was exceptionally strong at $21.8 million.

Brady Murphy, TETRA's President and Chief Executive Officer, stated, "We are pleased with our fourth-quarter performance and finishing 2025 with one of the strongest financial years in our history across our current segments. Total year 2025 revenue was $631 million, income from continuing operations before taxes was $26.5 million and Adjusted EBITDA was $114 million. Revenue and Adjusted EBITDA were the highest in the last 10 years. Completion Fluids & Products segment led the way with record revenue, Adjusted EBITDA and Adjusted EBITDA margins, supported by a record industrial chemicals performance and a very strong deepwater fluids market position. Additionally, we finished the year with the highest volumes and revenue ever for the recycling and treatment of produced water, including first revenue from desalination for beneficial re-use in the Permian Basin."

"The fourth quarter was highlighted by $31.7 million of cash from operating activities and $21.8 million in base business adjusted free cash flow. This further improved our already strong balance sheet, as evidenced by a net leverage ratio of 1.1 times net debt to Adjusted EBITDA and unrestricted cash on hand of $72.6 million at

------

year-end. Completion Fluids & Products Adjusted EBITDA margins were 28.2%. Water & Flowback Services Adjusted EBITDA margins were 12.9%."

"Additionally, we continued to make significant progress on the goals and milestones we outlined at our ONE TETRA 2030 Investor Day, which has received very positive feedback. We completed phase 1 of our Arkansas bromine project on time and under budget, placing and erecting the 120-foot-tall bromine tower and structure during the fourth quarter of 2025. We also secured access to additional volumes of bromine for 2026 and 2027 to meet incremental demand for completion fluids and electrolytes until our bromine plant is running, which is targeted for the fourth quarter of 2027. We completed the engineering study for a 25,000 bbls/day produced water desalination plant for beneficial reuse; however, our customers pivoted quickly in the fourth quarter by requesting engineering design for much larger-volume projects to support West Texas data center opportunities. We also executed a term sheet outlining the key parameters for a joint venture with Magrathea Metals, Inc. ("Magrathea") to monetize high concentrations of magnesium in our Arkansas brine. Magnesium is classified as a critical mineral by the U.S. government and is used to produce a highly valued metal for the Department of War and other U.S. industries. Deliveries of Eos electrolyte and PureFlow® continued to ramp up, and several capacity expansion projects at our plants, along with the added bromine supply, are expected to ensure we keep pace with their demand. It's been a very exciting year for TETRA, and we are on track to achieve our stated 2030 goals."

During the fourth quarter, Completion Fluids & Products revenues decreased 7% sequentially due to the timing of deepwater projects but increased 22% from the prior-year comparable period. Net income before taxes decreased 17% sequentially but increased 21% from the prior year's comparable period. Adjusted EBITDA decreased 14% sequentially but increased 25% from the prior year's comparable period.

Water & Flowback Services fourth quarter revenues were flat with the third quarter but down 4% year over year, materially less than the decline in U.S. frac activity, which was down 15% sequentially and down 24% from the fourth quarter of 2024 according to U.S. frac spread count data provided by Primary Vision as of December 31, 2025. While drilling and completions activity declined throughout the year, TETRA's Water & Flowback Services revenue remained relatively flat at $63 million to $64 million per quarter during the year, as market share gains offset weaker activity. Water & Flowback Services Adjusted EBITDA margins improved sequentially to 12.9% from 11.9%, driven by cost-reduction initiatives and continued market penetration leveraging our automation and technology.

Fourth-quarter Adjusted EBITDA margins were the highest of the year, despite the difficult U.S. onshore environment, reflecting TETRA's focus on cost reductions and technology. TETRA also secured contracts in Argentina's Vaca Muerta region that are expected to double our revenue in Argentina in 2026 over 2025, allowing us to continue to diversify our revenue base given the weaker U.S. onshore environment.

See Schedule F for an explanation of how we calculate Adjusted free cash flow and Base business adjusted free cash flow and a reconciliation to net cash provided by operating activities.

**<u>Full-Year 2025 Results</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenues of $631 million increased by 5% year over year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Income from continuing operations was $4.2 million including $31.6 million of unusual charges

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• EPS from continuing operations of $0.03 and Adjusted net income per share of $0.26 (compared to Adjusted net income per share of $0.17 in 2024)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $113.6 million increased 14% year over year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net cash provided by operating activities was $100 million; Adjusted free cash flow was $33 million and base business adjusted free cash flow was $83 million – materially above our expectations. Investments in Arkansas were $45 million in 2025, excluding capitalized interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cash at year-end was $72.6 million, net debt was $109 million and net leverage ratio was 1.1x, at year-end 2025.

"During 2025, our team delivered strong results reaching the highest levels in over ten years despite a very challenging oil price macro environment. For the full year, revenue and Adjusted EBITDA grew 5% and 14%, respectively. We generated $83 million in free cash flow from our base business driven by continued strength in our offshore completion fluids and industrial calcium chloride businesses plus a strong focus on working capital management. Net working capital was reduced from $109 million at year-end 2024 to $88 million at year-end 2025."

Completion Fluids & Products achieved impressive revenue and margin improvements driven by stronger volumes for our suite of high-density deepwater completion fluids products, the completion of three deepwater

------

wells in the Gulf of America using our proprietary TETRA CS Neptune fluid technology, stronger deepwater activity levels in Brazil and continued strong results from industrial calcium chloride.

"Water & Flowback Services successfully managed through a very challenging year, generating 11.9% of Adjusted EBITDA margins and Adjusted EBITDA of $30.4 million. Cost reductions in the United States, continued deployment of automation technology and market share gains in the Vaca Muerta in Argentina have positioned us for a solid year in 2026."

**<u>Balance Sheet and Cash Flow</u>** 

As of December 31, 2025, TETRA had cash and cash equivalents of $72.6 million, long-term debt of $181 million consisting of borrowings outstanding under our Term Credit Agreement, net debt of $108.7 million and a net leverage ratio (Net Debt/TTM Adjusted EBITDA) of 1.1 times. TETRA's unused ABL Credit Agreement matures May 2029, and the Term Credit Agreement matures January 2030.

Cash flow from operating activities during 2025 was $100 million. Total Adjusted free cash flow was $33 million. Base business Adjusted free cash flow was $83 million. Total capital expenditures were $81 million, including $45 million associated with the Arkansas project and $4.5 million of capitalized interest.

**<u>2026 Perspectives</u>**

"As we look towards 2026, we expect incremental revenue growth driven largely by a material increase in our electrolyte business and from a major contract awarded in Argentina. Because Gulf of America activity in 2025 was heavily weighted toward completion activity and less on drilling activity, 2026 customer activity is forecast to be higher in drilling, including more exploration, with less completion activity. As a result, we do not expect the Gulf of America to reach the same record levels as in 2025. However, this is projected to cycle into stronger 2027 completions activity. Our 2030 targets for this business are still very much on track. U.S. onshore Water & Flowback Services continues to benefit from longer laterals, increased sand and water usage, and more production-related activities, including water treatment and recycling. Outside the U.S., we will see a meaningful revenue increase driven by new early production facilities ("EPF") contracts in Argentina and new Sandstorm awards in the Middle East. We expect the net impact of these to result in overall modest revenue growth in 2026."

"We have secured third-party bromine supply for 2026 and 2027 to bridge our growing bromine demand until our bromine processing plant project is brought online. These third-party supplies will allow us to keep pace with the expected material increase in electrolyte from Eos and a robust deepwater market, but these bromine supplies are secured at an incrementally higher cost relative to our current long-term bromine supply agreement. Although it is possible one or more TETRA CS Neptune jobs could materialize in the second half of 2026, without TETRA CS Neptune projects and assuming somewhat higher costs of bromine, we expect our Completion Fluids & Products Adjusted EBITDA margins to be in the 25%-30% range in 2026, consistent with our average since 2019. The increased cost for additional bromine supply has been anticipated as a bridge until we have our bromine processing plant operational, but it further supports the significantly higher EBITDA we expect for this

------

segment starting in 2028. For Water & Flowback Services, the continued focus on differentiated technology and our profitable international growth are expected to contribute to improved Adjusted EBITDA margins from 12% in 2025 to mid-teens in 2026."

**<u>Progress on the Path to One TETRA 2030</u>**

"Since our September 2025 Investor Day, trends in future deepwater activity, adoption of our Sandstorm technology, electrolyte demand and the shift toward much larger-scale desalinated produced water projects for data center cooling and behind the meter power demands in West Texas have further strengthened our confidence in achieving our ONE TETRA 2030 objectives to more than double revenue and triple Adjusted EBITDA by 2030. We believe this strategic transformation will enable TETRA to generate more than $100 million in annual Adjusted free cash flow by 2030 and support meaningful return of capital to shareholders."

**Electrolytes for Utility Scale Battery Energy Storage Systems ("BESS")**

"As artificial intelligence and cloud computing drive rapid growth in data-center power demand, scalable long-duration energy storage is becoming increasingly critical. TETRA's proprietary PureFlow® zinc-bromide electrolyte is a key input for these systems, supporting safe, non-flammable performance at utility scale. Eos Energy Enterprises' decision to develop U.S. manufacturing capacity of 8 GWh annualized energy storage capacity validates commercial demand for our electrolyte, while government incentives for energy storage in place through 2035 provide visibility into increasing production volumes and the scalability of this business."

**TETRA Advances Produced Water Desalination Platform to Address Data Center Water Demand**

"The U.S. oil and gas industry is facing an increasingly urgent challenge in managing produced water, particularly in high-activity regions such as the Permian Basin, where more than 6 billion barrels of produced wastewater are injected annually into saltwater disposal wells according to Rystad Energy. Rising downhole formation pressures are constraining traditional disposal capacity and increasing regulatory scrutiny, while the rapid expansion of data centers is driving incremental demand for reliable and sustainable water supplies. Against this backdrop, we are advancing differentiated solutions through the commercial launch of TETRA Oasis TDS, our previously announced collaboration with EOG Resources, Inc. ("EOG"), and the engineering and design of a large-scale produced water treatment and recycling facility."

"Recent developments have helped establish TETRA as an early mover in this high growth market. In January 2026, we secured patent protection for our TETRA Oasis TDS technology and integrated end-to-end solution, further strengthening our proprietary technology position. We are currently engaged in active commercial discussions with multiple customers for a variety of end markets, including over multiple 100,000 barrel-per-day facilities to support growing power generation and data center water-cooling needs."

------

**<u>Arkansas Bromine Facility on Track for Completion By The Fourth Quarter of 2027</u>**

"We expect demand for our deepwater completion fluids and battery storage electrolytes to double by 2030, driving the need for reliable access to elemental bromine, a critical feedstock. To meet this accelerating demand while reducing third-party reliance and lowering our cost of bromine supply, we are advancing our bromine processing plant. Since inception, we have invested $46.5 million for the bromine project, excluding capitalized interest, funded from base business free cash flow while simultaneously improving our balance sheet."

In December 2025, we completed Phase 1 of the bromine processing plant project, including site preparation and installation of the bromine tower. We have commenced Phase 2, which includes significant infrastructure and equipment to support the plant, with mechanical completion targeted by the end of 2026. The entire facility is expected to be operational by the end of 2027, with first production in 2028. The plant will have annual capacity of up to 75 million pounds - more than double our existing long-term third-party supply agreement.

**Lithium & Magnesium Anchor Critical Mineral Growth Beyond 2030**

TETRA holds more than 40,000 acres of mineral-rich leases in Southwest Arkansas anchored by large-scale bromine, lithium and magnesium resources. With respect to lithium, this includes 65% ownership of 585,000 tons of lithium carbonate equivalent ("LCE") on approximately 6,900 acres and a 2.5% royalty from lithium sales expected to be generated by Smackover Lithium ("SWA"), a Standard Lithium/Equinor joint venture, on 35,000 acres of our 40,000 acres. Based on recent public disclosures, SWA is targeting to reach first lithium production in 2028.

"Also on our 40,000 acres, we have identified approximately 2.18 million tons of measured and indicated magnesium resources. The U.S. government has identified magnesium as a national security priority and a critical mineral feedstock for the defense, aerospace, and advanced manufacturing sectors. During the fourth quarter of 2025, we signed a term sheet to potentially form a joint venture with Magrathea to advance domestic magnesium metal production. As envisaged, the proposed joint venture will integrate our specialty chemical processing expertise and large-scale magnesium resource base with Magrathea's proprietary electrolytic magnesium production technology which has been underwritten in part by U.S. Defense Production Act Title III funding."

------

**<u>Unusual Charges and Expenses</u>**

Unusual charges and expenses, net of credits were $31.6 million for the year ended December 31, 2025, which are reflected in Schedules E and F, and include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $5.5 million of legal fees related to a former subsidiary, plus restructuring and severance as we downsized certain Water & Flowback Services operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $5.9 million of accrued expenses expected to be incurred through the expiration of our former corporate headquarters lease following our move to a nearby corporate office, which is expected to reduce annual operating expenses by approximately $2 million per year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $4.2 million of non-cash impairments, including a $3.6 million impairment of the right of use asset for our former corporate office lease and $0.6 million impairments of certain long-lived assets and right of use assets within Water & Flowback Services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $9.5 million non-cash cumulative accounting foreign exchange losses from the previous closure of our Canadian subsidiary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.4 million of non-cash stock appreciation right expense for our former CEO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $6.0 million of non-cash unusual tax expense (Schedule E), including $7.2 million tax expense from an election to reclassify our Brazilian subsidiary from a partnership to a corporation for U.S. tax purposes, partially offset by $1.2 million correction to our 2024 tax provision.

*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. See Schedules D through H for additional information.*

The most directly comparable GAAP financial measure is net income (loss) from continuing operations before taxes. 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 margin is defined as Adjusted EBITDA divided by revenues. A reconciliation of Adjusted EBITDA margin to the most directly comparable GAAP measures for future periods is not available without unreasonable efforts due to the inherent difficulty in forecasting and quantifying with reasonable accuracy activity levels and product mix, which significantly impact revenues. Such items are not currently determinable with reasonable accuracy and may be material to the Company's actual results determined in accordance with GAAP.

&nbsp;&nbsp;&nbsp;&nbsp;Total Adjusted free cash flow is defined as cash from operations, less capital expenditures net of asset sales, less payments on financing lease obligations plus cash distributions to the Company from investments and proceeds from sales of investments. Total Adjusted free cash flow does not necessarily imply residual cash flow available for discretionary expenditures. Base business Adjusted free cash flow is defined as total Adjusted free cash flow excluding TETRA's investments in the Arkansas project and capitalized interest associated with the Arkansas project. 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.

A reconciliation of Adjusted free cash flow to the most directly comparable GAAP measures for future periods is not available without unreasonable efforts due to the inherent difficulty in forecasting and quantifying with reasonable accuracy significant items required for the reconciliation including, among other things, depreciation expense and interest. Such reconciling items are not currently determinable pending finalization of cost estimates and funding structure, and may be material to the Company's actual results determined in accordance with GAAP.

**<u>Cautionary Statement Regarding Forward Looking Statements</u>**

This news release includes certain statements that are deemed to be forward-looking statements. Generally, the use of words such as "may," "see," "expectation," "expect," "intend," "estimate," "projects," "anticipate," "believe," "assume," "could," "should," "plans," "targets" or similar expressions that convey the uncertainty of future events, activities, expectations or outcomes identify forward-looking statements that the Company intends to be included within the safe harbor protections provided by the federal securities laws. These forward-looking statements include statements regarding our ability to achieve our One TETRA 2030 objectives with respect to revenue and Adjusted EBITDA as well as other 2030 goals discussed herein. These statements also include statements concerning economic and operating conditions that are outside of our control, including statements concerning the oil and gas industry; potential revenue associated with our electrolyte products and prospective energy storage projects; measured, indicated and inferred mineral resources of lithium, magnesium, and/or bromine, the potential extraction of lithium, bromine, magnesium and other minerals, including potential extraction of those minerals designated as critical minerals, from our Evergreen Unit and other leased acreage, the economic viability thereof, the demand for such resources, the timing and costs of such activities, and the expected revenues, including any royalties, profits and returns from such activities; the timing and success of our bromine production wells and the construction of our bromine processing facility and related engineering activities and estimated revenues and profitability thereof; projections or forecasts concerning the Company's business activities, including the completion of new projects, future results of operations, revenues, profitability, estimated earnings, earnings per share, estimated Adjusted EBITDA margins and 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 measured, indicated and inferred mineral resources, including bromine, lithium carbonate equivalent concentrations, and other minerals, it is uncertain if all such resources will ever be economically developed. Investors are cautioned that mineral resources do not have demonstrated economic value and further exploration may not result in the estimation of a mineral reserve. Further, there are a number of uncertainties related to processing lithium, which is an inherently difficult process. Therefore, you are cautioned not to assume that all or any part of our resources can be economically or legally commercialized. These forward-looking statements are based on certain assumptions and analyses made by the Company in light of its experience and its perception of historical trends, current conditions, expected future developments and other factors it believes are appropriate in the circumstances. Such statements are subject to several risks and uncertainties, many of which are beyond the control of the Company. With respect to the Company's disclosures regarding the potential joint venture with Magrathea and the potential joint venture for the Evergreen Unit, 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 magnesium, lithium, and/or bromine from TETRA's brine leases, including the Evergreen Unit. Investors are cautioned that any such statements are not guarantees of future performance or results and that actual results or developments may differ materially from those projected in the forward-looking statements. Factors which may cause actual results to differ materially from current expectations include, but are not limited to: changes in general economic conditions; opportunity risks, such as mineral extraction, demand therefor, or realizing industrial and other benefits expected from bromine processing; our ability to develop a bromine processing facility and risks inherent in the construction such facility; the accuracy of our resources report or the timing of future updates to our resources report, feasibility study and economic assessment

regarding our lithium, bromine and other mineral acreage; our ability to obtain any necessary additional capital to finance our development plans, including the construction of our bromine processing plant; equipment supply, equipment defects and/or our ability to timely obtain equipment components; competition from existing or new competitors; risks associated with changes in laws and regulations, or the imposition of economic or trade sanctions affecting international commercial transactions, including legislative, regulatory and policy changes, such as unexpected changes in tariffs, trade barriers, price and exchange controls; and other the factors described in the section titled "Risk Factors" contained in the Company's Annual Reports on Form 10-K, as well as other risks identified from time to time in its reports on Form 10-Q and Form 8-K filed with the Securities and Exchange Commission. Investors should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of the particular statement, and the Company undertakes no obligation to update or revise any forward-looking statements, except as may be required by law.
