**TETRA TECHNOLOGIES, INC. REPORTS STRONG FIRST-QUARTER 2026 RESULTS**

**MAINTAINS 2026 GUIDANCE**

SPRING, Texas, April 29, 2026 / PR Newswire / - TETRA Technologies, Inc. ("TETRA" or the "Company") (NYSE:TTI) announced financial results for the three months ended March 31, 2026.

**<u>First-Quarter 2026 Financial Highlights</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Revenues of $156.3 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Income from continuing operations of $8.3 million, inclusive of $0.5 million of unusual charges

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $25.6 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Income per share from continuing operations of $0.06

Brady Murphy, TETRA's President and Chief Executive Officer, stated, "We are pleased to start 2026 with one of the strongest first quarter performances in the company's past ten years. Excluding the benefit of TETRA Neptune in the prior-year period, consolidated first-quarter revenue of $156 million and Adjusted EBITDA of $26 million were ten-year highs for a first quarter, as were both Brazil and Gulf of America. In addition, the Industrial Chemicals and Production Testing subsegments each delivered ten-year-high revenues with strong margin contributions. High-pressure gas plays in Haynesville and South Texas, supporting Gulf Coast LNG, are areas that should experience rapid growth in the coming years."

The Middle East conflict did not materially affect our first-quarter results, as historically less than 5% of our revenue is exposed to this region. However, some completion fluid sales planned for the second quarter will likely be delayed. From a supply chain standpoint, our chemical manufacturing plants are located in the United States and Europe, and our elemental bromine is sourced from Arkansas. Over the longer term, it remains to be seen how developments in the Persian Gulf and the Middle East will impact the global oil and gas markets and our business and financial results, but in general we believe it will provide tailwinds to an already robust offshore and deepwater outlook and boost unconventional investment activity in the U.S. and Argentina.

Last September, we held an Investor Day at the NYSE, where we outlined a clear strategic path for the company. Although much has changed in the world since that event, our view of the company's key growth

------

trajectories across deepwater, specialty chemicals, electrolytes for battery energy storage, and desalination of produced water has strengthened. In addition, recent global events have prompted us to evaluate options to accelerate our Lithium and Magnesium critical minerals development. I am very pleased with the continued strong execution and performance of our base business and the progress we are making toward the strategic and financial targets we set as part of our ONE TETRA 2030 vision.

**<u>Maintaining 2026 Guidance</u>**

For 2026, our revenue and Adjusted EBITDA margins outlook remains unchanged with potential for upside if deepwater projects get accelerated or elevated oil and gas prices drive activity increases in the U.S. We expect to have a better view of the full year as we go through the second quarter. Total company revenue is expected to increase modestly driven by higher electrolyte sales and the execution of long-term contracts for early production facilities ("EPFs") in Argentina. Adjusted EBITDA margins for Completion Fluids & Products is expected to be in the 25-30% range and Water & Flowback Services in the mid-teens. Overall, we are off to a strong start and remain confident in our ability to deliver solid financial results this year while continuing to advance towards our 2030 targets.

<sup>(1) &nbsp;&nbsp;&nbsp;&nbsp;</sup>Adjusted EBITDA is a non-GAAP financial measure. See Schedule E for an explanation of how we calculate Adjusted EBITDA and reconciliation to net (loss) income from continuing operations before taxes.

<sup>(2)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Adjusted net income per share from continuing operations is a non-GAAP financial measure. See Schedule D for an explanation of how we calculate Adjusted net income per share from continuing operations and a reconciliation to net (loss) income from continuing operations before taxes.

<sup>(3)</sup> &nbsp;&nbsp;&nbsp;&nbsp;For the three months ended March 31, 2026, December 31, 2025 and March 31, 2025, total Adjusted free cash flow includes $6.6 million, $17.2 million and $11.2 million of net payments, respectively, for the Arkansas bromine and lithium projects, excluding capitalized interest. See Schedule G for an explanation of how we calculate Adjusted free cash flow and a reconciliation to net cash (used in) provided by operating activities.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Revenue of $91.7 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income before taxes of $24.3 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $25.7 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA margins of 28.0%

Completion Fluids & Products revenue increased 10% sequentially and decreased 1% year over year. Net income before taxes increased 16% sequentially and decreased 21% year over year. Adjusted EBITDA increased 12% sequentially and decreased 23% from the prior year comparable period. The year-on-year decline in revenue and Adjusted EBITDA was primarily a result of the absence of a TETRA Neptune project which did not repeat in the first quarter of this year. As deepwater offshore exploration activity increases, we expect targeted reservoirs to have higher pressures and temperatures, supporting the opportunity pipeline for high-density completion fluids, including TETRA Neptune, which continues to grow.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Revenue of $64.5 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income before taxes of $2.1 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $9.1 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA margins of 14.1%

Water & Flowback Services revenue increased 3% sequentially and 1% year over year. Our business has materially outpaced the 24% year-on-year decline in US frac activity and we are in a strong competitive position to incrementally benefit from any activity increase that may result from higher oil and gas prices. Water & Flowback Services net income before taxes increased 241% sequentially and decreased 123% year over year. Adjusted EBITDA increased 20% sequentially and increased 9% year over year driven by cost-reduction initiatives and market penetration of higher-margin automation technology. We expect profitability to improve in the coming quarters driven by project start-ups in Argentina's Vaca Muerta basin.

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

As of March 31, 2026, cash and cash equivalents was $35.5 million and total debt was $181.8 million. Net debt was $146.3 million and our net leverage ratio (Net Debt/TTM Adjusted EBITDA) was 1.5 times.

During the first quarter of 2026, cash used in operating activities was $11.9 million, total Adjusted free cash flow was a use of $31.9 million and base business Adjusted free cash flow was a use of $23.5 million. Total capital expenditures were $19.0 million, including $6.6 million associated with the Arkansas project and $1.8 million of capitalized interest.

**<u>Tracking Progress to ONE TETRA 2030</u>**

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

TETRA's electrolyte revenue grew meaningfully in 2025 as the U.S. Energy Information Administration (EIA) reports that a record 15 gigawatts ("GW") of utility-scale battery storage was added to the grid in 2025. The EIA projects that another record 24 GW is planned for 2026, representing a 60% growth rate. 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.

**Data Centers Provide New Produced Water Re-use Opportunity**

TETRA's OASIS TDS end-to-end desalination of produced water for beneficial reuse continues to gain momentum, with multiple engineering efforts and customer commercial engagements. Since establishing 24/7 steady-state operations over the past 50 days, our Permian Basin OASIS project has achieved 96% uptime and continues to meet our performance specifications. We believe that behind-the-meter self-power generation, access to affordable natural gas and land, and other factors will drive significant data center growth in West Texas and accelerate the produced water desalination market well ahead of our 2030 targets. Regulatory agencies continue to focus on understanding the technology, setting permitting standards, and encouraging the industry to bring solutions to the produced water disposal challenge. TETRA is honored to participate in the National Petroleum Council Produced Water Committee and to support the recently announced U.S. Environmental Protection Agency (EPA) Reuse Action Plan (WRAP) 2.0.

**Arkansas Bromine Facility on Time and on Budget**

We expect our bromine demand supporting our deepwater completion fluids and battery storage electrolytes to double by 2030, driving the need for and reliable access to cost effective elemental bromine, a critical feedstock. This has become more evident with the current events in the Middle East as well over 50% of the global bromine supply comes from that region. Our bromine construction project in Southwest Arkansas continues to proceed on time and on budget. Phase 2 of the project is underway with Phase 3 slated for 2027 and first production in 2028. The plant will have an annual capacity of up to 75 million pounds, more than double our existing long-term third-party supply agreement.

**Critical Mineral Extraction Provides Growth Beyond 2030**

TETRA holds more than 40,000 acres of mineral-rich leases in Southwest Arkansas anchored by large-scale lithium and magnesium resources. With respect to lithium, this includes royalty rights on lithium sales to be generated by Smackover Lithium ("SWA"), a Standard Lithium/Equinor joint venture, on 35,000 acres and 65% ownership of 585,000 tons of lithium carbonate equivalent ("LCE") on approximately 6,900 acres.

------

Also on our 40,000 acres, we have identified over 2 million tons of measured and indicated magnesium resources. We have finalized the formation of a joint venture with Magrathea Metals to advance domestic magnesium metal production and monetize this asset. The JV will leverage our specialty chemical processing expertise and large-scale magnesium resource base in combination with Magrathea's proprietary electrolytic magnesium production technology, which has been underwritten in part by the U.S. Department of War.

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

TETRA will host a conference call to discuss these results on April 30, 2026, at 10:30 a.m. ET. Please visit the Events & Presentations section of the TETRA Technologies <u>website</u> to listen to the call via live webcast.

Effective with this earnings release for the three months ended March 31, 2026, we revised our definitions of Adjusted EBIT and Adjusted EBITDA to exclude investment (income) losses. Prior period Adjusted EBITDA amounts have been recast to reflect these revised definitions for all periods presented. We changed the definitions of Adjusted EBIT and Adjusted EBITDA because management believes that investment (income) losses are not reflective of the underlying operating performance of our core business. Investment (income) losses consist of realized and unrealized gains and losses on equity and debt securities, including our investment in Standard Lithium, and investments in common units and preferred units issued by two privately-held companies as well as the option to convert a convertible note issued by a privately-held company into equity interests. Investment (income) losses are recorded in other income (expense), net in our consolidated statements of operations. The magnitude and timing of investment (income) losses are driven by factors external to our core operations that management cannot control and does not consider when evaluating or managing day-to-day business performance. Accordingly, management believes the revised definitions of Adjusted EBIT and Adjusted EBITDA provide more meaningful measures of our operating performance and improve period-over-period comparability. The revisions to the Adjusted

------

EBIT and Adjusted EBITDA definitions apply symmetrically to both investment income and investment losses, and we will apply this definition consistently in future periods.

Adjusted EBIT is now defined as net income (loss) from continuing operations before taxes, interest (income) expense, net, investment (income) losses, impairments and certain non-cash charges, and unusual adjustments.

Adjusted EBITDA is now defined as net income (loss) from continuing operations before taxes, excluding impairments, certain special, unusual or other charges (or credits), including loss on debt extinguishment, interest (income) expense, net, investment (income) losses, 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) 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.

**Schedule F: Unusual Charges and Credits (Unaudited)**

Unusual charges and expenses, net of credits were $0.5 million for the quarter ended March 31, 2026, which are reflected in Schedules D, E and I, and include $0.5 million of legal fees related to a former subsidiary, plus restructuring and severance as we downsize certain Water & Flowback Services operations.

*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, E and I for additional information.*

| &nbsp;&nbsp;Base Business Adjusted Free Cash Flow | $(23474) | $21776 | $16174 |

---

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.

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.
