LIBERTYSTREAM COMMENCES LITHIUM CARBONATE PRODUCTION AT SELECT WATER SOLUTIONS FACILITY AND SECURES FIRST U.S. PURCHASE ORDER

Libertystream Infrastructure Partners Inc. has begun production from its DLE (direct lithium extraction) unit and its lithium carbonate refining facility at Select Water Solutions' (New York Stock Exchange: WTTR) site in Howard county, northeast of Midland. The company has also presold its first tonne of production of lithium carbonate from its lithium carbonate operating facility for delivery in June, 2026. The first commercial sale is part of broader offtake discussions between Libertystream and an American consumer of lithium carbonate for a future offtake agreement. Libertystream anticipates derisking its scalable development model that it intends to replicate across high-volume United States basins, including the Permian and Bakken.

"We are proud of the pace of execution at Select's site," said Alex Wylie, president and chief executive officer of Libertystream. "We appreciate the confidence shown by our first customer as we work to convert our ongoing discussions into long-term offtake agreements. With production now under way, we are positioning the company to reach an annualized production capability of up to 1,000 tonnes of lithium carbonate by the end of 2026."

Lithium carbonate operating facility

Libertystream completed installation and construction of its lithium carbonate operating facility ahead of schedule in March, 2026, and has commenced production at the refining unit. The refining unit is engineered to produce both battery-grade and technical-grade lithium carbonate. The current configuration at Select's site incorporates key learnings from the company's prior field operations and is designed to enhance operating performance as Libertystream continues building its production history in the field. The company is actively collecting production and operating data, and expects to provide further updates as operations progress.

The first purchase order marks an important early milestone as Libertystream transitions from site deployment and systems integration into customer qualification and product sales. Aligned with the company's strategy of directing initial production into qualification and spot channels while advancing broader commercial relationships, the order provides early validation that Libertystream is delivering against the milestones set for its Texas operations. Following fulfilment of the purchase order, Libertystream will be making a royalty payment to Select.

Libertystream expects the Select site to remain a core operating and validation platform as the company advances customer qualification efforts, expands commercial sales and begins site preparation for the construction of its first Texas facility capable of annualized production 1,000 tonnes of lithium carbonate by end of 2026.
