Aqua Metals advances scalable ARC facility design and cost competitiveness as company eliminates debt

Earnings Call Insights: Aqua Metals, Inc. (AQMS) Q2 2025

MANAGEMENT VIEW

*
CEO Stephen Cotton stated that "this past quarter has been a defining period for Aqua Metals. We advanced our commercialization road map, achieved new technical milestones and strengthened our financial position, all of which position us for successful market entry." He highlighted production of lithium carbonate with fluorine content below 30 parts per million, describing it as "likely a best-in-class result globally for recycled lithium" and emphasized that this quality "meets and exceeds the strict specifications of cathode-active material producers." Cotton also reported production of over 1 metric ton of high-purity NMC mixed hydroxide cake for qualification sampling, and progress in testing alternative feedstocks, including nickel refinery residue and undersea nodules.

*
The company began designing a modular, scalable commercial ARC facility capable of processing between 10,000 and 60,000 metric tons of black mass annually, serving as a blueprint for scaling AquaRefining. Cotton noted ongoing discussions with potential strategic partners and emphasized internal analysis showing AquaRefining in the U.S. is cost competitive with Chinese hydrometallurgical recycling and operates at roughly half the cost of traditional U.S. hydrometallurgical methods.

*
CFO Eric West said, "We ended the quarter with cash and cash equivalents of approximately $1.9 million. And as of this call, we have approximately $3.2 million." West explained, "During June, we completed the sale of the Sierra ARC facility and related equipment, generating roughly $4.3 million of cash proceeds. These proceeds were used to retire the $3 million Summit building loan, which also eliminated the associated interest expense going forward. With the payoff of this note, the company now has no debt."

*
West also reported, "Operating expenses reflect prudent cost control and workforce reductions implemented to conserve cash while we pursue necessary capital funding. For the quarter, operations expenses were $0.8 million, down from $2.4 million a year ago, and G&A was $2.2 million, down from $3.4 million in Q2 of 2024."

OUTLOOK

*
The company is focused on securing supply and offtake partnerships to enable financing for its first commercial ARC facility. Cotton stated the company is "in a mode of we'll-build-it-when-they-come versus build-on-spec" and described the recent IP allowance and flexible offtake model as having "opened up meaningful new discussions and revenue opportunities."

*
Management did not provide explicit financial guidance figures for the upcoming quarters during the call.

FINANCIAL RESULTS

*
West reported net loss for the quarter was approximately $6.8 million, and basic and diluted net loss per share was negative $7.44 for Q2 of 2025 versus negative $9.94 in Q2 of 2024. Noncash items included an impairment and loss on the disposal of property and equipment of approximately $3.8 million in the quarter and $9 million recognized year-to-date as the company exited the Sierra ARC site.

*
Year-to-date cash used in operating activities was $5.3 million, reflecting improved cash management. Investing activities provided $4.9 million, mainly from asset sales. Financing activities used $1.8 million year-to-date, including $2.7 million raised through the ATM and $0.1 million via the Lincoln Park ELOC, with $4.5 million applied to principal repayments.

Q&A

*
Michael Frederick Legg, The Benchmark Company: Questioned progress on technology, cost competitiveness versus China, and customer interest. Cotton responded that reducing fluorine content in lithium carbonate to under 30 ppm "shows that sustainable recycling can meet or even exceed the standards of traditional supply chains," and that flexibility in product offerings is resonating with partners.

*
Legg asked about the recent tech showcase and industry engagement. Cotton said, "What stood out in my mind was the feedback and how many visitors call out the cleanliness and safety and organization of our innovation center... and the quality of materials that we're producing." Cotton described the event as generating "a really encouraging wave of engagement."

*
Legg inquired about macro factors, regulations, and trade policy. Cotton discussed ongoing efforts to encourage policies that incentivize domestic recycling, mentioning industry support for "a policy that encourages producers of black mass... to sell those materials domestically." Cotton referenced government support such as the DoD stockpiling cobalt and noted, "right now, there is about 0 tons per year of commercial quantities of recycling collectively in the industry."

*
Legg asked about financial flexibility and partnerships post-debt. Cotton credited asset divestiture and cash management for providing "a significant amount of runway and time to see through those discussions."

*
Robert Meyers, FNK IR: Asked about the patent allowance. Cotton explained, "this patent is really the unlock for that... we can now pursue further high-margin licensing joint ventures and other tech enablement types of deals."

*
Meyers asked about the surge in lithium prices after a major Chinese plant closure. Cotton noted, "That move really reverberated through the market immediately... and that really underscores though how thinly stretched supply chains have become."

*
Meyers inquired about next steps and milestones. Cotton identified focus on offtake partnerships, the impact of IP allowance, and ongoing new feedstock testing.

*
Meyers asked West about priorities as CFO. West said his top priority is "to continue the strong momentum that we've built on the fiscal side," focusing on "financial modeling and partner interface."

*
Meyers questioned the rationale for the reverse stock split. West responded, "the primary reason... was to support our efforts to regain full compliance with the NASDAQ listing requirements."

*
Meyers asked about the cost comparison study. West stated, "Our process is cost competitive with China and actually run at about half the cost of traditionally U.S. hydromet recycling."
