About this update from Tetra Technologies, Inc.

Using Neptune Chemistry to Achieve Required Density With Lower Zinc Content; Awarded Three-Well 20k psi Deepwater Project in the Gulf of America With Estimated Start in 2026SPRING, Texas, June 29, 2026 /PRNewswire/ -- TETRA Technologies, Inc. (NYSE: TTI) today announced the introduction of TETRA Neptune Z-Lite, a high-density completion fluid designed for deepwater and high-pressure well applications. The fluid system uses our patented Neptune fluid chemistry and expands the Company's completion fluids portfolio by offering up to 60% lower zinc-ion concentration than conventional zinc-based fluids while maintaining required density performance. TETRA has been awarded a three-well program for TETRA Neptune Z-Lite for Beacon Offshore Energy's Gulf of America Shenandoah and Monument projects expected to begin in 2026.TETRA Neptune Z-Lite reduces zinc-ion concentration, helping limit zinc returns from the wellbore and reduce refinery exposure. Available in densities up to 17.5 ppg, TETRA Neptune Z-Lite is thermally stable, solids-free, and designed to offer lower corrosion potential than conventional zinc brines. The fluid is compatible with most elastomers and formation fluids and can be recycled using standard field equipment."TETRA Neptune Z-Lite reflects our focus on fluid chemistry and on delivering differentiated completion fluids technology to meet customer needs in deepwater offshore markets," said Brady Murphy, president and chief executive officer of TETRA Technologies. "By applying our patented TETRA Neptune and our high-purity zinc bromide chemistries, we are leveraging the advantages of both. The Neptune chemistry improves corrosion performance while lowering zinc concentration, thereby reducing handling requirements across the wellsite, production facilities, and refineries."As deepwater developments target increasingly higher-temperature and higher-pressure reservoirs, TETRA Neptune Z-Lite is designed to deliver a lower life cycle well cost, which further strengthens the Company's position in the growing global deepwater markets.For more information about TETRA Neptune Z-Lite, click here. Company OverviewTETRA Technologies, Inc. is an energy services and solutions company focused on developing environmentally conscious services and solutions that help make people's lives better.
