TETRA TECHNOLOGIES, INC. ANNOUNCES EXPANSION OF SMACKOVER FORMATION EVERGREEN UNIT AND UPDATE ON ADDITIONAL TEST WELL RESULTS

THE WOODLANDS, Texas, April 24, 2025 /PRNewswire/ -- TETRA Technologies, Inc. ("TETRA" or the "Company") (NYSE:TTI) announced that on April 22, 2025 the Arkansas Oil & Gas Commission ("AOGC") approved TETRA's application to expand the previously approved Evergreen Unit from 6,138 gross acres to 6,953 gross acres.  A test well reported by a third party within the expansion unit acreage shows lithium concentrations above the estimated average within the original 6,138 acres Evergreen Unit, and based on reservoir studies conducted by Lonquist Engineering, the new expansion unit is expected to enhance and prolong the production of bromine and other minerals within the Evergreen Unit from the Smackover Formation.  The reservoir studies will be provided to the Company's "qualified person" for further evaluation.

The AOGC approved TETRA's application to establish the expansion unit and integrate landowners.  The formal AOGC order is expected to be finalized within the next 30 days.  Saltwerx, LLC is a participant in the Evergreen Unit, owning approximately 35% interest of the brine interests.  TETRA is the operator of the Evergreen Unit.

TETRA recently completed the drilling and sampling operations of an additional test well in the Evergreen Unit with very encouraging results. With the Evergreen Unit expansion approved and the additional test well results, the reservoir engineering model will be updated to reflect new resource volumes for bromine and lithium in the coming weeks.  In addition to the rich volumes of bromine and lithium in the expanded Evergreen Unit, recent test well results have shown encouraging levels of magnesium and manganese, which are on the U.S. list of critical minerals and which are largely supplied from countries outside the U.S.  Given TETRA's progress with mineral extraction from produced water, the Company is evaluating extraction technologies and development of these additional minerals, including engineering studies.  It is encouraging that all these minerals, three of which are on the U.S. critical minerals list, may be produced from the same brine that will be developed first for TETRA's bromine project requirements. 

TETRA is expected to publish an updated resource study prepared by the Company's qualified person identifying the incremental volumes of bromine and lithium in the expanded Evergreen Unit.  TETRA remains focused on developing the bromine assets and continues to advance engineering efforts as well as key timeline  investments to advance the project.

Also on April 22, 2025 the AOGC approved SWA Lithium's application to establish a unit for acreage under an option agreement between Standard Lithium, SWA Lithium and TETRA. The option agreement compensates TETRA with a 2.5% royalty on gross revenues from the lithium that Standard Lithium produces and sells from the TETRA option acreage.  TETRA maintains rights to the bromine and all other non-lithium minerals extracted from the brine produced by Standard Lithium in their approved unit.  Standard Lithium recently announced a joint venture agreement with Equinor to develop the TETRA option acreage to produce brine for lithium extraction.

Cautionary Statement Regarding Forward Looking Statements

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 TETRA intends to be included within the safe harbor protections provided by the federal securities laws. These forward-looking statements include statements regarding TETRA's beliefs, expectations, plans, goals, future events and performance, and other statements that are not purely historical. These forward-looking statements are based on certain assumptions and analyses made by TETRA 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 a number of risks and uncertainties, many of which are beyond the control of TETRA. Factors which may cause actual results to differ materially from current expectations include, but are not limited to: changes adversely affecting the business in which we are engaged; our ability to forecast trends accurately; our ability to develop a bromine processing facility; equipment supply, equipment defects and/or our ability to timely obtain equipment components; competition from existing or new competitors; opportunity risks, such as mineral extraction, demand therefor, or realizing industrial and other benefits expected from bromine processing; risks associated with changes in federal, state, or local laws or trade policies; and risks related to adverse changes in general economic conditions. With respect to our disclosures of mineral assets, including bromine and lithium concentrations, it is unclear whether they 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, investors are cautioned not to assume that all or any part of our resources can be economically or legally commercialized, or that it will ever be upgraded to a higher category.  Moreover, TETRA operates in a very competitive and rapidly changing environment, and new risks and uncertainties may emerge that could have an impact on the forward-looking statements contained in this press release. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and, except as required by law, TETRA assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.
