Aqua Metals Advances Commercialization of AquaRefining™ Technology with Industry-Leading Lithium Quality and Strategic Progress

Company eliminates long-term debt, strengthens balance sheet, and extends cash runway through asset sales and cost-reduction initiatives

RENO, Nev., August 13, 2025 — Aqua Metals, Inc. (NASDAQ: AQMS) (“Aqua Metals” or the “Company”), a pioneer in sustainable metals recycling, today announced financial results and operational highlights for the quarter ended June 30, 2025. The Company achieved significant progress toward commercialization, delivering best-in-class product quality, advancing key strategic initiatives, and fortifying its financial position.

Second Quarter and Recent Highlights:

Operational Initiatives

●

Produced Industry-Leading Low-Fluorine Lithium Carbonate: Reduced fluorine content in lithium carbonate to less than 30 parts per million (ppm), a likely best-in-class achievement in the global recycling sector, meeting the stringent specifications of cathode active material (CAM) producers. Approximately 100 kilograms of this high-quality material have been produced and are being sampled by strategic counterparties.

●

High-Purity NMC Cake Production: Produced over 1 metric ton of nickel-manganese-cobalt (NMC) mixed hydroxide cake for qualification sampling with potential partners.

●

Expanded Alternative Feedstock Testing: Exploring undersea mining nodules as a potential feedstock and the Company successfully tested nickel refinery residue as an additional potential feedstock.

●

Initiated Sodium Sulfate Regeneration Trials: Began testing an innovative sodium sulfate regeneration process designed to support precursor cathode active material (pCAM) producers by recycling the sodium sulfate they produce into chemicals they can use in their production process.

●

Advanced ARC Facility Design: Started design of a scalable AquaRefining™ Commercial (“ARC”) facility capable of processing 10,000 to 60,000 metric tons per year of black mass.

●

Demonstrated Cost Competitiveness: An internal study showed that AquaRefining™ in the U.S. is cost competitive with Chinese hydrometallurgical recycling and operates at approximately half the cost of traditional U.S. hydrometallurgical methods.

Financial Initiatives

●

Generated Cash from Non-Core Asset Sales: Completed the $4.3 million sale of the Sierra ARC facility and sold $200,000 in non-core equipment.

●

Strengthened Balance Sheet: Eliminated all long-term debt.

●

Improved Liquidity: Cash and cash equivalents increased from $1.6 million at the start of the quarter to over $1.9 million at quarter-end.

●

Extended Cash Runway: Gains driven by the building sale, implementation of the $10 million equity line of credit (ELOC), and reduced cash burn following the sale.

Milestone Announcements

●

Showcased Technology to Industry Leaders: Hosted over 100 stakeholders for live demonstrations at the Company’s Innovation Center and Demonstration Plant during NAATBatt’s annual meeting.

Strategic Engagements

Aqua Metals continues discussions with potential strategic partners. The Company believes collaboration among industry participants is critical as the U.S. builds domestic battery recycling and CAM production capacity—sectors where commercial-scale operations are still notably absent.

“Our industry has endured significant challenges over the past year as the global battery supply chain recalibrates,” said Steve Cotton, President and CEO of Aqua Metals. “These challenges also present a rare moment for leaders to step forward and work together. Our business model is built on collaboration—with suppliers, recyclers, technology innovators, and CAM producers—to help establish a fully domestic, commercially viable recycling and critical minerals ecosystem in the United States. We believe this quarter’s achievements, from delivering some of the lowest-fluorine lithium carbonate ever produced to demonstrating cost parity with Chinese recyclers, position Aqua Metals not just to participate in the emerging U.S. market, but to help define it.”

With industry-leading lithium carbonate quality, cost-competitive U.S.-based recycling, and a strengthened balance sheet, Aqua Metals has advanced both its technology and market position during the quarter. The Company believes that the elimination of long-term debt, extended cash runway, and progress on scalable ARC facility designs provide a clear path toward commercialization. Strategic engagements with potential partners, coupled with new intellectual property protection and successful technology demonstrations, reinforce Aqua Metals’ potential to play a defining role in building a domestic, closed-loop battery materials supply chain.
