Aqua Metals Reports Third Quarter 2025 Results and Highlights Continued Progress Toward Commercialization of AquaRefining™ Technology

Company secures $17.1 million in new funding, expands strategic partnerships, and advances commercial plans for lithium battery and critical minerals recycling

RENO, Nev., November 12, 2025 — Aqua Metals, Inc. (NASDAQ: AQMS) (“Aqua Metals” or the “Company”), a pioneer in sustainable battery metal recycling and refining, today announced financial results and recent corporate highlights for the quarter ended September 30, 2025.

Third Quarter 2025 and Recent Highlights

● In addition to raising $4.1 million throughout the quarter, raised $13 million from a single leading institutional investor as a subsequent event in October. This funding provides several quarters of significant runway for the Company to advance engineering, permitting, and site selection for Aqua Metals’ first commercial-scale facility. The Company is now positioned to complete detailed engineering and environmental reviews while remaining at an optimized cash burn rate in preparation for an accelerated launch once project financing is secured.  

● Advanced pilot-scale processing of LFP battery materials – Successfully processed 1 metric ton of lithium-iron-phosphate (LFP) cathode scrap and produced battery-grade lithium carbonate. As LFP adoption accelerates due to its safety and cost advantages, Aqua Metals remains the only recycler to demonstrate an economically viable process for LFP feedstock. The Company has modeled a 50/50 NMC (nickel-manganese-cobalt) -LFP commercial facility showing profitability at current metals pricing.

● Potential strategic partnerships across critical minerals supply chains

o Deep-sea minerals: Signed two MOUs with MOBY Robotics and Impossible Metals to explore clean refining of polymetallic nodules—abundant deep-sea resources rich in nickel, cobalt, manganese, and rare earth elements. These initiatives position Aqua Metals as a potential early leader in the sustainable processing of emerging deep-sea mineral feedstocks.

o Nickel supply: Signed a Letter of Intent (LOI) with Westwin Elements, a U.S.-based nickel refinery developer, outlining plans for the potential supply of 500–1,000 metric tons of recycled nickel carbonate annually. At current market prices, this could represent roughly $12 million in annual contract value and would contribute to building one of the first fully domestic nickel supply chains.

● Regained compliance with NASDAQ minimum-bid requirement – An important milestone maintaining Aqua Metals’ listing and investor confidence as the Company transitions toward commercial operations.

● Participated in The Battery Show North America 2025 – Presented progress on the AquaRefining™ platform and met with OEMs and recycling partners to expand commercial engagement opportunities.

● Attended the 2025 Battery Recycling Workshop in Quzhou, Zhejiang, China, organized by GDMCC – gathered market intelligence and engaged with additional global OEMs and recycling partners.

Market Landscape

The global lithium-battery-recycling sector is undergoing a technology-driven consolidation as early entrants face scale and cost challenges. Meanwhile, underlying demand remains strong: EV sales grew 11% year-over-year, grid-storage deployments continue to rise, and more than 45 battery-manufacturing facilities are planned or under construction across North America.

This rationalization phase is paving the way for technically validated and financially resilient companies like Aqua Metals to capture outsized market share as recycling volumes accelerate over the next five years with fewer capitalized operators to process these volumes. Market forecasts estimate that the black mass produced in the US by 2030 will exceed 250,000 MT annually, containing an estimated value of critical minerals to be $1.2 billion at today’s metals prices.   

Management Commentary

“Q3 was one of the most productive periods in our company’s history,” said Steve Cotton, President and CEO of Aqua Metals. “With the bolstering of our balance sheet, successful LFP pilot runs, and multiple strategic partnerships undergoing evaluation- from undersea minerals to domestic nickel refining - we’re executing on our vision for a feedstock-agnostic, low cost, low-carbon refining platform that supports U.S. supply-chain independence.”

“Our technology continues to demonstrate adaptability across both terrestrial and marine feedstocks, giving Aqua Metals unique flexibility as the clean-energy transition enters a renewed phase of investment and growth,” Cotton added. “We are very pleased with our strengthened resilience while securing the right long-term partners and capital to scale our operations responsibly and profitably.”
