Standard Lithium Ltd. announced that Karen Narwold will resign from its Board of Directors effective September 15, 2026, due to a new executive role requiring increased time commitments. Following her departure, the board will consist of eight directors while the company initiates a search for a replacement independent director. Standard Lithium Ltd. is a near-commercial lithium development company focused on sustainable production from high-grade brine properties in Arkansas and Texas.

Standard Lithium Ltd.'s Smackover Lithium partnership announced a binding take-or-pay offtake agreement with LG Energy Solution for the South West Arkansas Project. The contract commits to supplying 8,000 metric tons annually of battery-grade lithium carbonate over ten years. This deal brings total committed offtake volume to approximately 90% of the project's initial phase nameplate capacity, following a prior agreement with Trafigura. The partnership targets a Final Investment Decision in 2026, with construction planned to begin promptly thereafter and first commercial production expected in 2029. Standard Lithium Ltd. operates in the lithium mining industry, developing projects to produce battery-grade lithium carbonate.

Standard Lithium Ltd. announced a Preliminary Economic Assessment for the Franklin Project, its first lithium development in East Texas via the Smackover Lithium partnership with Equinor. The study outlines an unlevered after-tax NPV of $5.0 billion and an IRR of 24% based on up to 70,000 tonnes per year of battery-quality lithium carbonate production over a 20-year life. Initial CAPEX is estimated at $3.5 billion with average annual cash operating costs of $4,226 per tonne. The project leverages Direct Lithium Extraction technology similar to the South West Arkansas Project and includes upgraded mineral resources containing significant bromide and potash potential. Standard Lithium operates in the critical minerals sector, developing lithium brine extraction projects.

Standard Lithium Ltd., via its Smackover Lithium partnership with Equinor, signed a binding take-or-pay offtake agreement with LG Energy Solution for the South West Arkansas Project. The deal commits the project to supply 8,000 metric tonnes per year of battery-quality lithium carbonate over a 10-year period following commercial production start-up. This agreement complements a prior contract with Trafigura, bringing total committed offtake volume to approximately 90% of the targeted initial phase capacity. The partnership aims for a Final Investment Decision this year, targeting construction commencement and first commercial production in 2029. Standard Lithium Ltd. is a lithium development company focused on sustainable direct lithium extraction from brine resources in the United States.

Standard Lithium Ltd. filed a Form 6-K incorporating by reference an NI 43-101 Technical Report detailing a maiden inferred resource estimate for its Franklin Project in East Texas, USA. The project is operated by Smackover Lithium, a joint venture between Standard Lithium (55% interest) and Equinor (45% interest). Based on 617 brine leases covering 32,455 hectares, the report estimates an inferred resource of 406,000 metric tonnes of elemental lithium, 2,638,000 metric tonnes of bromide, and 8,070,000 metric tonnes of potassium. These resources are contained within the Upper and Middle Smackover Formation aquifers at depths ranging from approximately 2,865 to 3,810 meters subsea. The company operates in the lithium extraction industry, focusing on direct lithium extraction (DLE) from subsurface brine reservoirs.
