Aqua Metals and WMC Sign LOI Covering 100% of Planned Lithium Carbonate Output from First Commercial-Scale AquaRefining™ Facility
Rhea-AI Summary
Aqua Metals (NASDAQ:AQMS) signed a non-binding six-year letter of intent with WMC Group covering 100% of the planned lithium carbonate output from Project Headwaters, its first commercial-scale AquaRefining facility in the U.S. Midwest. Headwaters is expected to produce about 7,000 metric tons of lithium carbonate from 2028 through 2032, starting at 250 metric tons in 2028 and ramping to 2,250 metric tons annually by 2032. At current market prices, Aqua Metals estimates this output implies roughly $135 million in illustrative gross value, though actual revenue will depend on future prices, qualification and production. The LOI includes market-indexed pricing and collaboration on feedstock sourcing, tolling and product qualification, with a definitive offtake agreement targeted by September 30, 2026. The company also highlights a recent commercial sale of battery-grade lithium carbonate and potential future collaboration with WMC’s affiliate Liminal for additional deployments in Europe and further U.S. refining capacity.
Positive
- LOI covers 100% of Headwaters lithium carbonate output for six years, subject to definitive agreement
- Planned 7,000 metric tons lithium carbonate production 2028–2032, ramping to 2,250 metric tons annually by 2032
- Illustrative gross value of planned lithium carbonate output about $135 million at current pricing
- Recent commercial sale of battery-grade lithium carbonate in the U.S. at market-based pricing
- LOI includes market-indexed pricing and collaboration on feedstock sourcing, tolling and product qualification
- LOI contemplates additional U.S. refining products and potential future AquaRefining deployments via WMC affiliate Liminal
Negative
- LOI is non-binding except for customary provisions; no assured definitive offtake agreement
- Financing, construction schedule and production volumes for Project Headwaters are not guaranteed
- Illustrative $135 million gross value is not contracted revenue, backlog or guaranteed future sales
- Actual realized revenue will depend on future commodity prices, product qualification, final pricing terms and production
News Explained
The signed but non-binding LOI’s proposed offtake is limited to refined lithium, nickel and cobalt products; recovered aluminum, copper, graphite, iron phosphate and other recovered materials, intermediates and by-products require separate agreement.

Project Headwaters aims to be first commercial-scale deployment of AquaRefining™ for lithium carbonate production
Planned output of approximately 7,000 metric tons through 2032 represents roughly
RENO, Nev., Aug. 31, 2026 (GLOBE NEWSWIRE) -- Aqua Metals, Inc. (NASDAQ: AQMS) (“Aqua Metals” or the “Company”), a leader in sustainable lithium-ion battery recycling, today announced that it has signed a non-binding six-year letter of intent (“LOI”) with WMC Group AG(“WMC”), a global, leading commodity merchant active in the battery raw material value chain, covering
Once operational, Project Headwaters is expected to produce approximately 7,000 metric tons of lithium carbonate through 2032, beginning with 250 metric tons in 2028 and ramping to 2,250 metric tons annually by 2032. Based on current market pricing, those produced volumes would represent approximately
The LOI provides for market-indexed pricing and contemplates collaboration between Aqua Metals and WMC on feedstock sourcing, tolling and product qualification. The parties are targeting execution of a definitive offtake agreement by September 30, 2026.
U.S. Policy Creates Urgent Need for Domestic Refining Capacity
The agreement comes as U.S. policy is fundamentally reshaping the domestic battery recycling market.
On July 30, 2026, the President issued a determination under the Defense Production Act identifying recoverable critical minerals, including lithium-ion battery black mass, as “industrial resources necessary to promote the national defense.” Beginning August 27, 2026, a new Bureau of Industry and Security rule requires U.S. persons selling lithium-ion battery black mass to allocate
“Project Headwaters was designed around the premise that the United States needs the ability not only to collect and process spent batteries, but to refine those materials domestically into products that can re-enter the supply chain,” said Steve Cotton, President and Chief Executive Officer of Aqua Metals. “The United States needs the ability to collect and process spent batteries, and to refine those materials domestically into products that can re-enter the supply chain. Federal policy is now reinforcing that need.”
Commercial Validation of Aqua Metals’ Battery-Grade Lithium Carbonate
The LOI follows the Company’s recent commercial sale of battery-grade lithium carbonate produced through its recycling platform to a U.S. customer at market-based pricing, direct evidence that recycled lithium from the AquaRefining platform meets customer requirements and commands market pricing.
“We have moved past demonstrating that we can produce battery-grade lithium carbonate,” Cotton said. “We have sold it commercially in the United States at market pricing, and WMC has signed an LOI covering the planned Headwaters output. Both steps de-risk the commercial case for the project.”
“WMC is pleased to work with Aqua Metals as it advances Project Headwaters and expands domestic battery-material refining capacity. We believe that their ability to produce high-quality products, combined with our market expertise, will help strengthen the US critical mineral supply chain,” said Sander Elting, Chief Executive Officer of WMC.
European Deployment Under Discussion
Beyond the Project Headwaters offtake relationship, the LOI contemplates broader collaboration between Aqua Metals and Liminal by WMC, an integrated partner of WMC Group, which is developing battery recycling, metals recovery and refinery facilities across the Netherlands and Canada.
Aqua Metals believes that collaboration could over time create opportunities for the deployment or licensing of AquaRefining™ technology in additional markets, including Europe. Any technology licensing, deployment or joint-development arrangement would be subject to separate negotiation and definitive agreements.
Additional U.S. Refining Opportunity
The broader WMC LOI also contemplates refined products from additional U.S. recycling and refining capacity currently under development by Aqua Metals in response to the changing domestic market created by the new restrictions on black mass sales.
The proposed offtake applies only to refined lithium, nickel and cobalt products and does not include recovered aluminum, copper, graphite, iron phosphate or other recovered materials, intermediates or by-products unless separately agreed between the parties.
The LOI is non-binding, except for certain customary provisions. There can be no assurance that Aqua Metals and WMC will enter into a definitive agreement, that Project Headwaters will be financed or constructed on the anticipated schedule, or that anticipated production volumes or values will be achieved.
