LibertyStream signs lithium carbonate offtake with U.S. customer

Definitive agreement covers 600 tonnes per year beginning in 2027, with pricing set for first two years of planned Freedom 1 supply LibertyStream Infrastructure Partners Inc. (TSXV: LIB | OTCQB: VLTLF | FSE: I2D) (“LibertyStream” or the “Company”) is pleased to announce that it has entered into a definitive lithium carbonate offtake agreement with its previously announced U.S. industrial customer. The definitive agreement follows the term sheet announced on June 8, 2026, and formalizes a multi-year supply relationship for U.S.-produced lithium carbonate from Freedom 1, LibertyStream’s first 1,000 tonne-per-annum commercial-scale facility being developed at Select Water Solutions’ Howard County site. Under the initial delivery schedule, LibertyStream will supply 600 tonnes per year of lithium carbonate beginning in 2027, delivered in quarterly shipments of 150 tonnes.

Pricing has been set for the first two years of planned supply. At Freedom 1’s 1,000 tonne-per-annum design basis, the agreement represents 60% of planned annual output. “Finalizing this agreement turns customer qualification into a contracted delivery schedule,” said Alex Wylie, President & CEO of LibertyStream. “For Freedom 1, 600 tonnes per year with two years of pricing provides a clear demand anchor as we move toward customer delivery planning. It matters for customers, shareholders, and potential capital partners because it links planned production to a definitive commercial contract.” Demand Anchor for Freedom 1 The agreement connects planned Freedom 1 production to a defined customer delivery schedule and provides pricing visibility for the first two years of supply.

The contracted volume, delivery timing, and initial pricing framework are expected to be useful inputs as LibertyStream evaluates capital options and advances Freedom 1. Customer and Delivery Coordination The agreement provides a framework for continued coordination with the customer on product specifications, quality control, packaging, logistics, and delivery planning ahead of expected 2027 supply. LibertyStream expects to provide further updates as Freedom 1 preparation, customer delivery planning, and capital activities advance.
