Aqua Metals Advances Headwaters ARC, a Scaled Midwest Battery Recycling Campus Targeting the LFP Manufacturing Corridor

Aqua Metals, Inc. (NASDAQ: AQMS), a sustainable critical minerals recovery and lithium battery recycling company, announced on July 7, 2026 that it has entered final site-specific diligence and negotiations for Headwaters ARC, a planned commercial battery recycling and critical minerals recovery campus in the Midwest. The site under evaluation includes approximately 150,000 square feet of existing industrial infrastructure and 50 or more acres of land—more than seven times the footprint and ten times the land area of the company’s previously planned Sierra ARC facility. Aqua Metals expects to announce its selected development path before the end of the current quarter.

LFP Chemistry Is Growing Fastest, Yet Has the Fewest Dedicated Recycling Solutions

Lithium iron phosphate has emerged as the dominant battery chemistry for grid-scale energy storage, AI datacenter backup power, and an increasing share of electric vehicle production, driven by its cost, safety, and cycle-life advantages. North American LFP gigafactory capacity is on pace to grow roughly 15 times by 2030, according to third-party industry research cited by Aqua Metals. That scale-up will generate enormous volumes of manufacturing scrap and end-of-life material—yet LFP remains underserved by existing recyclers, who built most of their infrastructure around nickel- and cobalt-bearing chemistries. Unlike NMC batteries, LFP contains no cobalt or nickel to subsidize processing economics, so efficient recycling requires a purpose-built pathway that maximizes recovery of aluminum, copper, black mass, and lithium carbonate. Headwaters ARC is designed specifically around that pathway.

The Site’s Location Directly Adjacent to Six LFP Gigafactories Is the Strategic Core

Aqua Metals designed Headwaters ARC to sit within a short driving distance of six major LFP gigafactory projects in the Great Lakes battery manufacturing corridor. That proximity matters for two reasons. First, it dramatically reduces inbound logistics costs for the manufacturing scrap that will constitute Headwaters ARC’s initial feedstock. Second, and more importantly, it positions Aqua Metals as a natural offtake partner for cell manufacturers who need a recycling solution close to their production line—a regulatory and sustainability requirement that is already appearing in customer supply chain specifications. Being the nearest credible recycler to multiple gigafactories is a structural advantage that a competitor entering the region later would take years to replicate.

A Phased Build Matches Capital Deployment to Commercial Milestones

Rather than committing to a capital-intensive greenfield buildout upfront, Aqua Metals structures Headwaters ARC as a phased deployment. Phase 1 focuses on infrastructure readiness and deploying commercially proven preprocessing systems to produce black mass, aluminum fines, and copper fines from LFP feedstocks. Phase 2 expands processing capacity, builds out feedstock and offtake relationships, and begins generating revenue and cash flow. Only after establishing that commercial foundation does the company intend to integrate its proprietary AquaRefining™ technology for full battery-grade lithium carbonate and iron phosphate recovery. This sequencing lets Aqua Metals begin generating revenue at a lower capital threshold while preserving the higher-value refining upside for later phases.

AquaRefining™ Validates the Long-Term Technology Edge

AquaRefining™ is an electrified hydrometallurgical process that recovers critical materials from lithium-ion battery feedstocks while regenerating and recycling key process chemicals. Unlike conventional approaches that generate large volumes of sodium sulfate waste—a costly disposal burden—AquaRefining™ eliminates sodium sulfate as a principal waste stream. The technology has now accumulated more than 5,000 cumulative operating hours at Aqua Metals’ Innovation Center and pilot plant at the Tahoe-Reno Industrial Center, and it has demonstrated recovery of battery-grade lithium carbonate from LFP feedstocks, independently confirmed to battery-grade specifications. That validation record gives Aqua Metals a credible technical foundation to build on as Headwaters ARC progresses through its phased rollout. In June 2026, the company was also selected as an industrial partner on a DOE-funded Idaho National Laboratory program advancing critical minerals refining—a further endorsement of the platform’s scientific standing.

Capital Efficiency Structures Reduce Upfront Corporate Exposure

Aqua Metals has engaged Newmark’s Advanced Manufacturing Practice Group to advise on capital formation strategies that minimize dilutive financing. Newmark is evaluating structures under which third-party real estate and infrastructure capital—potentially through a long-term triple-net lease—could fund acquisition of the land and building and certain tenant improvements, thereby covering a substantial portion of initial capital requirements without drawing on corporate cash. In parallel, the company is working with equipment and technology suppliers to structure staged payment terms aligned with project milestones and commercial ramp-up. Together, these approaches are designed to let Aqua Metals focus its own capital on operations and working capital rather than real estate and equipment acquisition—preserving flexibility while the development plan takes shape. The company intends to select its Phase 1 preprocessing equipment partner and announce the arrangement in the near term.

Strategic Investment Summary

• Milestone Announced: Aqua Metals (NASDAQ: AQMS) announced on July 7, 2026 that it has entered final site-specific diligence and negotiations for Headwaters ARC, a planned Midwest battery recycling and critical minerals recovery campus.
• Site Scale: The site under evaluation includes approximately 150,000 square feet of existing industrial facilities and 50 or more acres of land—over seven times the building footprint and ten times the land area of the previously planned Sierra ARC project.
