SELECT WATER SOLUTIONS AND LIBERTYSTREAM INFRASTRUCTURE PARTNERS ANNOUNCE DEFINITIVE AGREEMENT TO BUILD OUT COMMERCIAL LITHIUM CARBONATE PRODUCTION UNITS IN TEXAS; FIRST 1,000-TONNE FACILITY SLATED FOR COMMISSIONING BY DECEMBER 2026

Select Water Solutions Inc. and Libertystream Infrastructure Partners Inc. have entered into a definitive agreement to deploy commercial lithium carbonate production facilities at Select's water treatment and recycling sites in the Midland basin, Texas. The agreement outlines a three-stage development program for these carbonate facilities, with the initial phase scheduled for commissioning by the end of December, 2026. The stage 1 carbonate facility will have a production capacity of up to 1,000 tonnes of lithium carbonate per year for sale to United States customers and will be located at an existing Select facility in Howard county, Texas.

Select's chairman of the board, president and chief executive officer, John Schmitz, commented: "This project leverages Select's market leading infrastructure network while unlocking the resource value inherent in the large volumes of produced water that move through it each day. By integrating lithium extraction into our existing water platform, we are creating meaningful incremental value from assets already in place. This is precisely the type of multiuse infrastructure initiative that supports our long-term growth strategy and enhances the durability of our profitability."

"We have made tremendous progress scaling our lithium extraction and carbonate refining processes in the Permian basin over the past 18 months," said Alex Wylie, president and chief executive officer of Libertystream. "We have been preparing for commercial production throughout the past year, and we are excited to partner with Select -- an organization with the experience, infrastructure and operational reach needed to unlock the vast lithium resource contained in Permian basin oil field brines."

Select and Libertystream agreement

Site preparation for the stage 1 carbonate facility is scheduled to begin in March, 2026, with full site construction commencing in the latter half of the second quarter of 2026. Upon commissioning in December, 2026, the stage 1 carbonate facility will be capable of producing up to 1,000 tonnes per annum of battery grade lithium carbonate from the Select facility in Howard county, Texas.

As part of stage 2, Libertystream will commission a second carbonate facility on or before June, 2027, designed to process up to 1,000 tonnes of battery grade lithium carbonate per annum. As part of stage 3, beginning in July, 2027, Libertystream will commission at least two additional carbonate facilities at existing Select facilities across Howard, Martin, Midland, Upton and Glasscock counties, Texas.

Select's water recycling and pretreatment capabilities will play a critical role in Libertystream's lithium extraction process. By removing a major pretreatment step required for direct lithium extraction, Select's systems reduce both capital and operating costs across Libertystream's carbonate facilities.

This project reflects Select's strategy to unlock new value streams from its existing water infrastructure -- transforming oil and gas waste streams into shareholder value and enhancing returns on invested capital. By increasing the utility of its pipeline network, disposal wells, treatment systems and monitoring infrastructure, Select is advancing its broader capital strategy: maximizing returns from its asset base by layering on incremental, high-margin revenue streams supported by fixed offtake and pricing agreements.
