Smackover Lithium Signs LG Energy Solution for 8,000 Tonnes a Year, Reaching 90% of Its Offtake Target

Smackover Lithium signed a binding take-or-pay offtake agreement with LG Energy Solution on August 31. The South West Arkansas Project will supply 8,000 metric tonnes per year of battery-quality lithium carbonate over 10 years, starting when commercial production opens. Smackover Lithium is a partnership between Standard Lithium and Equinor, run from Lewisville, Arkansas. The deal is the project’s second commercial offtake. It lifts committed volume to roughly 90% of the total offtake the partners set out to sell.

Two contracts, one financing test

The LG contract matches the Trafigura agreement the partners announced in March 2026. That deal also runs 8,000 metric tonnes per year for 10 years. Together the two contracts commit 16,000 tonnes a year.

The 90% figure needs its denominator stated plainly, because two different ones are in play. The project’s initial phase carries a nameplate capacity of 22,500 metric tonnes of lithium carbonate a year. The partners set out to contract roughly 80% of that nameplate, or about 18,000 tonnes. The 16,000 tonnes now signed is about 90% of that target, and about 71% of nameplate. Smackover Lithium says it expects to sign one more, smaller agreement.

Neither company disclosed pricing. The release states that pricing and other key commercial terms “are subject to confidentiality but are structured to support anticipated financing for the Project.” Regional coverage in Arkansas put the contract’s value at an estimated $1.5 billion over the decade. Treat that as an outside estimate rather than a disclosed figure, because the parties published no price.

Why It Matters

Offtake contracts are the gate to project debt, and that is the real function of this announcement. Smackover Lithium reported indications of interest for over $1 billion in project debt from three export credit agencies in a December 9, 2025 financing update. Standard Lithium chief executive David Park tied the two together directly, saying the partnership has “secured a vast majority of the offtake agreements needed to move forward with our Project financing plans and a Final Investment Decision.”

That sequencing sets the schedule. The partners target a final investment decision this year. Construction starts promptly after that decision, and first commercial production of battery-quality lithium carbonate follows in 2029. Some trade coverage has described construction as starting in 2026 without that condition attached. The release makes the start contingent on the investment decision, so the 2029 production date rests on an approval that has not happened yet.

For storage buyers, the relevant point is where the lithium units sit. LG Energy Solution runs seven production facilities in the United States, and most already build LFP cells for storage. Pairing domestic cell plants with an Arkansas carbonate source shortens a supply chain that has depended on imported material. That matters more now that imported grid equipment faces new federal trade restrictions. The catch is timing. The cells exist today, and the Arkansas carbonate does not arrive until 2029 at the earliest.

Smackover Lithium plans to produce the carbonate through direct lithium extraction and purification rather than evaporation ponds. The project has drawn support from the U.S. Department of Energy’s critical minerals work.

Critical Perspective

The 90% headline number is measured against a target the partners chose, not against what the plant would produce. Against the initial phase nameplate of 22,500 tonnes a year, the 16,000 tonnes now committed is about 71%. Both figures are accurate. Only one of them describes how full the plant is.

This is also an offtake for a plant that does not exist yet. There is no final investment decision, construction has not started, and first production is targeted for 2029. The take-or-pay obligation runs from the start of commercial production, so a schedule slip moves the buyer’s commitment with it. The contract secures financing for the seller more than it secures lithium for the buyer on any fixed date.

Treat the valuation with care. The parties disclosed no price and said terms are confidential. The $1.5 billion figure comes from regional press, and dividing it by the 80,000 tonnes the contract covers implies roughly $18,750 per tonne. That is a demanding price assumption for battery-grade lithium carbonate over a decade that has not started. The number belongs to whoever estimated it, not to the companies.
