**TETRA TECHNOLOGIES, INC. ANNOUNCES** 

**STRONG THIRD QUARTER 2025 RESULTS**

<u>Third Quarter 2025 Financial Highlights</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Revenue of $153 million increased 8% year over year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income before taxes of $8.1 million was flat year over year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $25.0 million increased 7% year over year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Earnings per share were $0.03. Adjusted earnings per share were $0.04

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net cash provided by operating activities was $16.4 million, while base business free cash flow (defined below) was $5.4 million

THE WOODLANDS, TEXAS, October 28, 2025 / PR Newswire / - TETRA Technologies, Inc. ("TETRA" or the "Company") (NYSE:TTI) announced third quarter 2025 financial results.

Brady Murphy, TETRA President and Chief Executive Officer, stated, "Our employees delivered another strong quarter, contributing to a ten-year high adjusted EBITDA of $93 million for the first nine months of 2025. Third quarter results of $25.0 million of adjusted EBITDA, 16.3% of adjusted EBITDA margins and $5.4 million in base business free cash flow were achieved despite ongoing weakness in the U.S. onshore oil and gas markets. The team delivered an 8% year-over-year improvement in revenue driven by continued strength in our offshore and industrial calcium chloride businesses.

"Through the first nine months of the year, Completion Fluids & Products' adjusted EBITDA margin reached 34.5%, a 500 basis point improvement compared to the same period in 2024 driven by the successful completion of three TETRA CS Neptune wells in the Gulf of America along with increased demand for high density zinc-based bromine brines, strong contributions from Brazil deepwater projects and robust calcium chloride results in Northern Europe."

"Third quarter Completion Fluids and Products revenues increased 39% compared to the previous year period, with adjusted EBITDA rising by $6.9 million. Water & Flowback Services revenue declined 2% sequentially, despite a 12% drop in frac activity from the second quarter. Adjusted EBITDA margins improved to 11.9% from 9.9% driven by cost reduction initiatives and continued market penetration of automation and new technology."

"We ended the third quarter with $67 million of cash on hand and a net leverage ratio of 1.2 times trailing twelve month adjusted EBITDA. Our focus on operational execution and fiscal discipline continues to support our

------

Arkansas investments and emerging growth initiatives. We remain focused on increasing return on capital and maximizing free cash flow."

"On the emerging growth initiatives, we are encouraged by the progress Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos") continues to make in automating their manufacturing assembly line to support the volumes of electrolyte they will require from us. We have completed the installation of our bulk electrolyte tanker loading system at our West Memphis plant and expect a significant increase in electrolyte volumes in early 2026. Following the commercial launch of our TETRA Oasis TDS water desalination technology, we engaged a third-party engineering firm and started the design for our first commercial 25,000/bbl per day facility. The Front-End Engineering and Design ("FEED") has been completed, and the estimated capital and operating expenses are within our initial projections for the project. This step is facilitating commercial discussions with multiple customers who have signed non-disclosure agreements ("NDAs")."

"Through the first nine months of the year, we have generated $58 million of base business free cash flow and invested $28 million towards the development of our Arkansas bromine processing facility, including prepping the site, laying initial foundation and pilings and positioning to receive the bromine tower in the fourth quarter. We are on schedule and under budget for Phase 1 of the project and remain confident that the plant will be fully operational by year-end 2027."

**Full Year Guidance**

For the full year 2025, TETRA expects GAAP net income before taxes to be between $19 million and $27 million (previously $21 million and $34 million), which includes an expected $8 million non-cash charge related to our corporate office lease (see Schedule I below). We expect adjusted EBITDA to be between $107 million and $112 million (previously $100 million and $110 million) and revenue to be between $620 million and $630 million (previously $610 million and $630 million). The non-cash corporate office lease charge reflects TETRA's planned move to a nearby corporate office in The Woodlands that is expected to reduce lease expense by approximately $2 million per year compared to the existing lease arrangement. These guidance ranges are subject to, among other risks, those associated with timing of completion fluid projects, changes to oil and gas company spending plans and activity levels, and macro impacts from U.S. tariffs.

---

<sup>(1) &nbsp;&nbsp;&nbsp;&nbsp;</sup>For the three months ended September 30, 2025, June 30, 2025 and September 30, 2024, total adjusted free cash flow includes $6.0 million, $10.9 million and $8.7 million, respectively, of investments in the Arkansas bromine and lithium projects. 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. See Schedule F.

**<u>Completion Fluids & Products</u>** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Revenue of $90 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income before taxes of $25.3 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $27.6 million and adjusted EBITDA margins of 30.5%

Completion Fluids & Products revenue decreased 18% sequentially but increased 39% from the prior year comparable period. Net income before taxes decreased 34% sequentially (the second quarter is a seasonal high for our calcium chloride business) but increased 32% from the prior year comparable period. Adjusted EBITDA decreased 31% sequentially but increased 34% from the prior year comparable period. In the current quarter, adjusted EBITDA margins were 30.5%. During the first nine months of 2025, Completion Fluids & Products achieved impressive revenue and margin improvement 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, high activity levels in our deepwater Brazil operations and continued strong results from our industrial calcium chloride business.

The long-term outlook for the Completion Fluids & Products business remains solid driven by strong deepwater completion activity and exceptional performance in our industrial chemicals business. For full year 2025, we expect Completion Fluids revenue to reach a ten-year high. Looking into 2026, we expect to see a material increase in battery electrolyte revenue as Eos ramps up deliveries from its first automated production line.

------

**<u>Water & Flowback Services</u>** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Revenue of $63 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income before taxes of $0.1 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $7.5 million and adjusted EBITDA margins of 11.9%

Water and Flowback Services revenue decreased 2% from the second quarter and 18% year over year, materially less than the decline in U.S. frac activity (down 12% sequentially and down 27% from the second quarter of 2024 according to U.S. frac spread count data provided by Primary Vision as of September 30, 2025). Adjusted EBITDA increased 18% sequentially on better cost controls but decreased 33% from the prior year comparable period on weaker volumes. Sequentially, adjusted EBITDA margins of 11.9% increased 200 basis points from 9.9%, driven by increased utilization of our patented automated TETRA SandStorm and Auto-Drillout units, efficiency improvements and cost controls.

Despite a soft outlook for the U.S. frac crew count, we expect our onshore testing and flowback business will benefit from two industry trends: longer laterals and increased sand and water usage, plus our continued move into production related activities. Outside of the U.S., we are positioned to benefit from increased unconventional oil and gas activity in Argentina and the Middle East. As such, we will continue to invest in these high margin, high return product lines.

**<u>Phased Development of Arkansas Bromine Project</u>**

We expect demand for our deepwater completion fluids and battery storage electrolytes to double by 2030. Elemental bromine is a critical feedstock for these products. To meet this accelerating demand, reduce reliance on third-party suppliers and gain access to a lower cost of supply, we continue to advance our bromine processing plant. Since embarking on this project in 2022, we have invested over $40 million in the project, which has been funded from our base business free cash flow.

By year-end 2025, we expect to have Phase 1 of the project completed, including site preparation, power infrastructure and installation of the bromine tower. Phase 2 will include major infrastructure and equipment supporting the plant with completion projected by the end of 2026. Overall, the facility is expected to be operational by the end of 2027, with first production in 2028. The plant will have the capacity to process 75 million pounds of bromine per year, more than double that of our current third-party supply agreements.

As noted in the 2024 Definitive Feasibility Study and Economic Analysis ("DFS"), the facility can enable TETRA to generate incremental revenue and adjusted EBITDA of between $200 million to $250 million and $90 million and $115 million per annum, at full production, respectively. The adjusted EBITDA target contribution is underpinned by lower input costs and additional volumes for the battery electrolyte and deepwater completion markets.

*The economics of our bromine processing plant discussed in this release are based on a number of key assumptions, which are further discussed in the DFS which is available on our website. Please read the DFS and the assumptions discussed therein for further information. Such assumptions are based on information known to*

*RESPEC Company, LLC and TETRA as of the date of the DFS, are subject to change and actual results may differ materially from the economics and assumptions presented in the DFS.*

**<u>One TETRA 2030</u>**

At our investor day event on September 25, 2025 we unveiled ONE TETRA 2030 - a strategy focused on leveraging our core fluids chemistry expertise into new high-growth end markets, notably delivering battery electrolytes for long-duration energy storage and oil and gas produced water desalination solutions. As envisioned, we are charting a path toward three operating segments: Specialty Chemicals & Minerals, Water Treatment & Desalination and Energy Services. As these businesses evolve, our future reporting will reflect this strategic realignment.

Our goal is to more than double revenue to over $1.2 billion and triple adjusted EBITDA to over $300 million by 2030. At that point, approximately two-thirds of our business will be derived from Specialty Chemicals & Minerals and Water Treatment & Desalination and one-third from Energy Services. We believe that this transformation will enable TETRA to generate over $100 million in annual adjusted free cash flow and drive meaningful cash returns to shareholders.

**<u>One TETRA 2030 Growth Initiatives</u>**

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

As artificial intelligence ("AI") and cloud computing drive increasing energy demand, Eos' zinc-based long-duration storage systems are gaining traction for their safety, scalability, and domestic sourcing. TETRA's

------

proprietary PureFlow® zinc-bromide electrolyte is a critical component of these systems, offering flame-retardant properties and high purity levels.

Underpinning this, Eos recently announced it will expand its manufacturing capacity in Pennsylvania with plans to reach 8 GWh of annualized energy storage capacity, which validates strong commercial momentum for the use of our electrolyte in long-duration battery energy systems and underpins our confidence in achieving the revenue and EBITDA growth we outlined during our investor day in September. We believe this positions TETRA as a key enabler of AI infrastructure aligning with national priorities around energy security and supply chain independence.

**Produced Water Desalination, Recycling and Beneficial Reuse Solutions**

The U.S. oil and gas industry is facing an increasingly urgent challenge in managing produced water, particularly in high-activity regions like the Permian Basin, where over 6 billion barrels of wastewater are injected into saltwater disposal wells annually, according to Rystad Energy. This traditional method of deep underground injection is becoming less viable as downhole formation pressures continue to rise, prompting heightened concern from both regulators and industry stakeholders.

With the commercial launch of TETRA Oasis TDS, our previously announced collaboration with EOG, and the engineering and design of the industry's first 25,000 barrel per day produced water treatment and recycling facility, TETRA is well positioned to help solve this problem. Our pilot field is now treating produced water to the standards required by the EPA, the Texas Railroad Commission and our customers' requirements.

Significant progress continues to be achieved with our produced water desalination project. TETRA has received the FEED study validating our capital and operating expense assumptions for the first plant. This milestone enables us to initiate commercial engagement with prospective customers, and we remain confident in signing our first contract in early 2026. Securing this initial agreement would represent a key inflection point and serve as a catalyst towards achieving the Water Treatment and Desalination revenue and earnings targets outlined at our September investor day.

**<u>Cash Flow and Liquidity Update</u>**

Cash from operating activities generated during the third quarter of 2025 was $16.4 million. Total adjusted free cash flow was a use of cash of $0.6 million. Base business adjusted free cash flow was $5.4 million. Total capital expenditures were $15.7 million, including $6.0 million associated with the Arkansas bromine processing facility.

Liquidity at the end of the **third** quarter was $208 million, inclusive of an unused $75 million delayed draw feature under our Term Credit Agreement. Liquidity is defined as unrestricted cash plus availability under our ABL Credit Agreement, Swedish Credit Facility and the delayed draw from our Term Credit Agreement. As of September 30, 2025, TETRA had cash and cash equivalents of $67 million, long-term debt of $181 million consisting of borrowings outstanding under our Term Credit Agreement, net debt of $114 million and a net leverage ratio (Net

------

Debt/TTM Adjusted EBITDA) of 1.2x. TETRA has no near-term maturities as the unused ABL Credit Agreement matures May 13, 2029 and the Term Credit Agreement matures January 1, 2030.

**<u>Conference Call</u>**

TETRA will host a conference call to discuss these results tomorrow, October 29, 2025, at 10:30 a.m. Eastern Time. Participants in the United States can listen to the conference call by dialing 1-800-715-9871.

---

Adjusted EBITDA is defined as net income (loss) before taxes and discontinued operations, excluding impairments, certain special, non-recurring or other charges (or credits), including loss on debt extinguishment, interest, depreciation and amortization 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. 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 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. 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. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assess the Company's ability to retire debt;

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

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

---

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, repurchase stock, and fund investing and financing activities.

---

Net leverage ratio is defined as debt excluding financing fees and discount on term loan and including finance lease obligations, other capital purchase liabilities, 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, and fund investing and financing activities.

When we exit our current corporate office, which may occur as early as the fourth quarter of 2025, we expect to record a non-cash charge of approximately $8 million, primarily related to an approximate $5 million impairment of the right of use asset and approximately $3 million of accrued facility management and operational costs, which are offset by concessions from the new lease. TETRA expects lease expense in the new facility to be approximately $2 million lower per year compared to the current office lease.

No quantitative reconciliation of Adjusted EBITDA Targets for 2030 to the most directly comparable GAAP measure is available without unreasonable efforts due to the inherent difficulty in forecasting and quantifying with reasonable accuracy significant items required for reconciliation. Key items required to establish a comparable target include, among other things, depreciation expense and interest. Such reconciling items are not currently determinable pending finalization of cost estimates, 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>**

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 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 and/or bromine, the potential extraction of lithium, bromine 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, profitability, estimated earnings, earnings per share, 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 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 lithium and bromine from 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.
