STANDARD LITHIUM LTD. (SLI), through its Smackover Lithium partnership with Equinor subsidiaries, reports a second binding take-or-pay commercial offtake agreement for its South West Arkansas Project with LG Energy Solution. The Project will supply 8,000 metric tonnes per year of battery-quality lithium carbonate to LG Energy Solution over a 10-year period following the start of commercial production.
The Project’s initial phase is designed for 22,500 metric tonnes per year of nameplate lithium carbonate capacity and is seeking offtake agreements for roughly 80% of that volume. Combined with a previously announced Trafigura agreement for another 8,000 metric tonnes per year over 10 years, roughly 90% of the total targeted offtake volume is now committed.
The partnership previously reported indications of interest from three major Export Credit Agencies for over $1 billion in potential project debt. It is targeting a Final Investment Decision in 2026, with construction planned to begin promptly afterward and first commercial production of battery-quality lithium carbonate expected in 2029.
Standard Lithium Ltd. (SLI), through its 55%-owned Smackover Lithium partnership with Equinor, released a positive Preliminary Economic Assessment for the Franklin lithium brine project in East Texas. The PEA outlines an unlevered after-tax NPV8 of $5.0 billion, an after-tax IRR of 24.0% and a 3.1-year after-tax payback, based on a lithium carbonate price of $22,400/t.
The study contemplates annual production capacity of up to 70,000 tpa of battery-quality lithium carbonate, averaging about 65,000 tpa over a 20‑year life, supported by an initial CAPEX of $3.5 billion (capital intensity about $49,900/t). Average cash operating costs are estimated at $4,226/t, with all‑in costs of $5,054/t. The updated Mineral Resource includes 1.77 million tonnes LCE Indicated and 2.13 million tonnes LCE Inferred, plus significant bromide and potash resources, over 44,541 hectares of project area.
The PEA is preliminary and incorporates both Indicated and Inferred resources, which the company states are too speculative at this stage to be classified as Mineral Reserves, and it notes results are highly sensitive to lithium prices and the production schedule. The partnership plans to advance Franklin to a Preliminary Feasibility Study targeted for completion in 2027.
Standard Lithium Ltd. (SLI), through its Smackover Lithium partnership with Equinor, announced a binding take-or-pay offtake agreement for the South West Arkansas Project with LG Energy Solution. The SWA Project will supply 8,000 metric tonnes per year of battery-quality lithium carbonate to LG Energy Solution over a 10-year period following the start of commercial production. Pricing and other commercial terms are confidential but are described as supporting anticipated project financing.
The SWA Project targets customer offtake agreements covering roughly 80% of its initial 22,500 metric tonnes per year nameplate lithium carbonate capacity. Combining this agreement with the previously announced Trafigura offtake for 8,000 metric tonnes per year means about 90% of the targeted offtake volume is now committed. Smackover Lithium has received indications of interest for over $1 billion in project debt from three Export Credit Agencies, with due diligence underway. The partnership is targeting a Final Investment Decision this year, with construction planned to begin promptly afterward and first commercial production expected in 2029. Standard Lithium holds a 55% interest in the projects, with Equinor holding 45%.
Standard Lithium Ltd. reported a maiden NI 43‑101 Inferred Mineral Resource for the Franklin lithium‑brine project in east Texas, held via the Smackover Lithium joint venture with Equinor (55% Standard Lithium, 45% Equinor). The resource is hosted in the Upper and Middle Smackover Formation beneath a project area of 32,455 ha, with estimates based on 18,732 ha of gross leased brine mineral rights and extensive well, core, seismic, and brine sampling data.
The Inferred Resource totals 406,000 tonnes lithium (2,159,000 tonnes LCE), 2,638,000 tonnes bromide, and 8,070,000 tonnes potassium, contained in 0.61 km³ of brine, with average lithium concentrations around 668 mg/L. These resources are classified as Inferred and are explicitly stated not to have demonstrated economic viability or to constitute mineral reserves.
Independent Qualified Persons conclude that drilling, logging, coring, and analytical work support the Inferred classification and recommend further work to upgrade confidence and advance project definition. Suggested next steps include re‑entering 2023 wells for additional sampling and production testing, drilling two more exploration wells, updating geological and reservoir simulation models, and conducting targeted metallurgical test programs, with total recommended work of approximately US$19.5 million.

Standard Lithium Ltd. reports successful downstream battery testing using lithium carbonate from its South West Arkansas (SWA) Project. About one kilogram of battery-quality lithium carbonate, produced from SWA brine via the project’s process flowsheet, was supplied to Nano One Materials Corp.
Nano One used this material in its patented One-Pot process to make lithium iron phosphate (LFP) cathode active material and coin cell batteries in North America. The resulting material showed suitable chemical and physical properties, the intended particle morphology, and delivered approximately 155 mAh/g on first discharge in initial electrochemical testing, providing additional validation of the SWA process flowsheet and suitability of its lithium carbonate for downstream battery applications.
Standard Lithium Ltd. entered into a new Sales Agreement with Canaccord Genuity LLC, Canaccord Genuity Corp. and Evercore Group L.L.C. to issue and sell from time to time common shares having an aggregate offering price of up to US$50,000,000 as "Placement Shares". Sales may be made as at-the-market offerings on the TSX Venture Exchange and NYSE American under the company’s existing short form base shelf prospectus and Form F-10 shelf registering up to US$1,000,000,000 of securities.
The company already has a prior US$50,000,000 ATM program under which 8,978,213 shares have been sold for proceeds of US$36,012,156, leaving US$13,987,844 of capacity that will be used before issuing Placement Shares under the new agreement. Authorized capital includes an unlimited number of common shares, with 246,411,248 common shares outstanding as of the agreement date.
Standard Lithium Ltd. reported operational progress for the three and six-month periods ended June 30, 2026, focused on advancing the South West Arkansas (SWA) lithium project and its broader Smackover portfolio.
The U.S. Department of Energy completed its National Environmental Policy Act review of the SWA Project with a Finding of No Significant Impact, satisfying a key requirement linked to a previously awarded $225 million DOE grant. The company executed two major construction agreements: an EPCC contract with S&B Engineers and Constructors for the central processing facility and an EPCM contract with Wood Group USA for the upstream well field, both with Limited Notices to Proceed ahead of a potential Final Investment Decision (FID).
At its Arkansas demonstration plant, Standard Lithium achieved processing of 1 million barrels of brine, over 15,000 Direct Lithium Extraction cycles, and roughly 340,000 man hours with zero incidents. As of June 30, 2026, the company reported $137.3 million in cash, $137.1 million in working capital, and no term or revolving debt, while targeting FID later in 2026 and first commercial lithium carbonate production in 2029.
