Standard Lithium adds 4,000-tonne annual supply option
Potential annual offtake of 20,000 metric tonnes exceeds the project's 18,000-tonne target, with financing due diligence underway at three Export Credit Agencies.
Rhea-AI Filing Summary
Standard Lithium said the Smackover Lithium partnership with Equinor amended its binding commercial offtake agreement with Trafigura. Smackover Lithium may elect to supply up to an additional 4,000 metric tonnes of battery-quality lithium carbonate per year, on top of the initial 8,000 metric tonnes; maximum possible Trafigura deliveries on a take-or-pay basis are now 12,000 metric tonnes per year under the 10-year agreement beginning at commercial production.
Alongside a binding take-or-pay agreement with LG Energy Solution for 8,000 metric tonnes per year, total possible offtake commitments have reached 20,000 metric tonnes per year, above the initial target of roughly 80% (18,000 tonnes) of the project’s 22,500-tonne annual nameplate capacity. Due diligence and customary financing processes are underway with three major Export Credit Agencies. The project targets around $1.1 billion in senior secured, limited recourse debt financing, a Final Investment Decision later this year, and first commercial production in 2029.

Filing Explained
Project financing can proceed without an additional offtake agreement, the company says.
The amended Trafigura agreement lets Smackover allocate the optional extra volume to other strategic customers, rather than committing that volume solely to Trafigura.

Smackover Lithium Exceeds Targeted Customer Offtake Volumes for South West Arkansas Project
Amendment to Trafigura agreement provides Project with the option to deliver up to an additional 4,000 metric tonnes of battery-quality lithium carbonate per year, on top of the initial 8,000 metric tonne per year commitment
All figures are in US dollars unless otherwise stated.
LEWISVILLE, Ark., Sept. 28, 2026 (GLOBE NEWSWIRE) -- Smackover Lithium, a partnership between Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (NYSE.A: SLI) (TSXV: SLI), through its subsidiaries, and Equinor, through subsidiaries of Equinor ASA, today announced that it has amended its binding commercial offtake agreement (the “Agreement”) with Trafigura Trading LLC (“Trafigura”) for the South West Arkansas Project (“SWA Project” or the “Project”). The amendment provides the additional offtake volumes targeted to complete the Project’s customer offtake process and move to finalize the ongoing debt financing process.
Trafigura is a market leader in the global commodities industry, with an established presence across battery metal markets, including lithium. As one of the largest commodity traders in the world, Trafigura provides valuable access to multiple industry supply chains that rely on lithium chemicals along with a broad suite of customers.
Under the amended terms of the Agreement, Smackover Lithium now has the option, at its own election, to supply Trafigura with up to an additional 4,000 metric tonnes of battery-quality lithium carbonate in each year of the 10-year Agreement beginning at the start of commercial production. Combined with the initial 8,000 metric tonnes per year commitment under the Agreement, the maximum possible volumes to be delivered to Trafigura on a take-or-pay basis has increased to 12,000 metric tonnes of battery-quality lithium carbonate per year. Pricing and other key commercial terms remain subject to confidentiality.
The amended Agreement also provides valuable production flexibility for the Project. Because the additional volume is deliverable solely at Smackover Lithium’s election, it retains the ability to allocate that volume to other strategic customers in the future if a superior commercial or strategic opportunity emerges. Importantly, an additional offtake agreement is not required to move forward with the Project financing process.
The target for the SWA Project was to secure customer offtake agreements for roughly 80% (18,000) of the 22,500 tonnes of annual nameplate lithium carbonate capacity in its initial phase. Together with the recently announced binding take-or-pay agreement with LG Energy Solution for 8,000 metric tonnes per year, total possible commitments have now reached 20,000 metric tonnes of battery-quality lithium carbonate per year, exceeding the initial target.
Smackover Lithium now has sufficient offtake commitments to focus on finalizing its Project debt financing efforts. Due diligence and other customary processes in furtherance of Project financing are well underway with three major Export Credit Agencies. The Project continues to target a senior secured, limited recourse debt financing package of around $1.1 billion as outlined in its financing update on December 9, 2025.
David Park, Chief Executive Officer of Standard Lithium, stated, “This is a pivotal milestone for the SWA Project and a testament to the strength of our customer relationships. The offtake process has been one of the most important and time-intensive workstreams and we now have the volume commitments needed to support our Project debt financing, as well as the flexibility to continue to pursue transactions that maximize value for our stakeholders. Our path forward is clear as we focus on finalizing and closing the Project financing, taking FID and beginning construction.”
Having successfully completed the commercial offtake workstream, Smackover Lithium continues to target a Final Investment Decision (FID) on the SWA Project later this year before moving promptly into construction. This would enable first commercial production of battery-quality lithium carbonate in 2029.
