Company Description
Aqua Metals, Inc. (NASDAQ: AQMS) is a metals recycling company focused on sustainable, low-emissions recovery of battery materials. According to the company’s disclosures and recent press releases, Aqua Metals is commercializing its proprietary, patented AquaRefining™ technology to recycle lithium-ion batteries and other critical mineral feedstocks. The company describes its approach as non-polluting and aimed at closing the loop on critical minerals used in clean energy technologies, electric vehicles, grid storage, and advanced manufacturing.
Aqua Metals states that it is based in Reno, Nevada, with facilities located in the Tahoe-Reno Industrial Center. Its common stock, with a par value of $0.001, trades on the Nasdaq Capital Market under the ticker symbol AQMS, as reflected in multiple Form 8-K filings. The company positions AquaRefining™ as a low-temperature, electro-hydrometallurgical platform that can produce high-purity, low-carbon battery materials from lithium-ion battery black mass and other feedstocks.
Business focus and AquaRefining™ platform
In its public communications, Aqua Metals describes itself as a pioneer in sustainable battery metals recycling and refining. The AquaRefining™ process is presented as an alternative to conventional smelting and traditional hydrometallurgical methods, with the company highlighting reduced emissions, elimination of waste streams, and lower environmental impact. The technology is used to recover critical minerals such as lithium, nickel, cobalt, manganese, copper and other battery-relevant materials from manufacturing scrap, end-of-life batteries, and, in development programs, additional feedstocks.
Recent updates indicate that Aqua Metals has produced battery-grade lithium carbonate from lithium-iron-phosphate (LFP) cathode scrap and has also produced nickel-manganese-cobalt (NMC) mixed hydroxide cake for qualification sampling. The company reports that it has achieved low-fluorine lithium carbonate levels that it characterizes as meeting stringent specifications for cathode active material producers. Aqua Metals also notes internal studies suggesting that its AquaRefining™ process in the United States is cost competitive with Chinese hydrometallurgical recycling and operates at a lower cost than traditional U.S. hydrometallurgical methods.
Lithium-ion battery recycling and critical minerals
Aqua Metals’ recent press releases emphasize a strategic focus on lithium-ion battery recycling and the broader critical minerals supply chain. The company is advancing plans for its first commercial-scale AquaRefining™ Campus (ARC) facility, which it describes as capable of processing significant volumes of black mass when fully developed. Design work has been initiated for an ARC facility sized in a range of tens of thousands of metric tons per year of black mass, with the goal of returning battery-grade materials into domestic supply chains.
The company also reports that it is exploring alternative feedstocks beyond conventional battery recycling, including undersea mining nodules and nickel refinery residues. These efforts are framed as part of a broader vision for a feedstock-agnostic refining platform that can adapt to terrestrial and marine sources of critical minerals. Aqua Metals has begun bench-scale testing to adapt its process to polymetallic nodules and has disclosed successful testing of nickel refinery residue as a potential additional feedstock.
Partnerships and supply-chain positioning
Aqua Metals’ news releases highlight multiple memoranda of understanding (MOUs) and a Letter of Intent (LOI) that outline potential commercial relationships across the critical minerals and battery materials ecosystem. The company has signed MOUs with MOBY Robotics Inc. and Impossible Metals, Inc. to evaluate the use of AquaRefining™ for refining deep-sea polymetallic nodules containing nickel, cobalt, manganese, copper, and rare earth elements. These collaborations are described as focused on developing sustainable, domestic pathways for critical mineral production.
In addition, Aqua Metals has entered into a non-binding LOI with Westwin Elements, which it describes as America’s only major nickel refinery, to negotiate definitive terms for the supply of between 500 and 1,000 metric tons of recycled nickel carbonate annually. The company reports that battery-grade nickel carbonate produced at its Nevada pilot facility from lithium-ion battery black mass has passed Westwin’s technical and economic qualification process. Aqua Metals characterizes this contemplated supply relationship as a potential contributor to one of the first fully domestic nickel supply chains.
Commercialization path and capital structure
The company’s filings and earnings releases indicate that Aqua Metals is in the process of transitioning from pilot and demonstration operations toward commercial deployment of its AquaRefining™ technology. It has reported pilot-scale processing of LFP battery materials, production of high-purity NMC cake, and live technology demonstrations for industry stakeholders at its Innovation Center and demonstration plant.
To support this transition, Aqua Metals has undertaken several capital-raising and balance sheet initiatives. The company has disclosed a registered direct offering and concurrent private placement that together generated gross proceeds of approximately $13 million, through a combination of common shares, pre-funded warrants, and private placement warrants. It has also reported the use of an equity line of credit, sales of non-core assets, and the elimination of long-term debt. These steps are described as strengthening liquidity, extending cash runway, and providing growth capital to advance engineering, permitting, and site selection for the first commercial ARC facility.
Regulatory status and listing
According to multiple Form 8-K filings, Aqua Metals’ common stock is registered under Section 12(b) of the Securities Exchange Act and listed on the Nasdaq Capital Market under the symbol AQMS. In 2025, the company received notices from Nasdaq regarding non-compliance with the minimum bid price requirement and potential delisting. Aqua Metals disclosed that it appealed to a Nasdaq Hearings Panel and implemented a reverse stock split, and it later reported that Nasdaq confirmed the company had regained compliance with the minimum bid requirement. The company remains subject to a panel monitoring period related to this listing standard.
Corporate governance and shareholder matters
A definitive proxy statement (DEF 14A) filed in 2025 outlines Aqua Metals’ annual meeting agenda, including the election of directors, approval of potential share issuances under a purchase agreement, authorization of a reverse stock split within a specified ratio range, amendments to the company’s stock incentive plan, ratification of the independent registered public accounting firm, and an advisory vote on executive compensation. These proposals reflect the company’s efforts to manage its capital structure, maintain exchange listing compliance, and align equity incentives with its strategic objectives.
Industry context as described by the company
In its own commentary, Aqua Metals situates its business within the clean energy transition and the build-out of domestic critical mineral supply chains. The company notes that demand for electric vehicles, grid storage, and battery manufacturing capacity in North America is driving interest in recycling and refining solutions that can reduce reliance on foreign-controlled supply chains. Aqua Metals references public discussions around U.S. critical minerals stockpiles and national security considerations, and it presents AquaRefining™ as aligned with these policy and market themes.
Summary
Overall, Aqua Metals, Inc. describes itself as a clean metals recycling company focused on lithium-ion battery recycling and critical minerals refining using its AquaRefining™ technology. With headquarters in Reno, Nevada, listing on the Nasdaq Capital Market, and a portfolio of pilot operations, partnerships, and planned commercial facilities, the company aims to supply high-purity, low-carbon battery materials and to participate in the development of domestic, circular supply chains for key energy-transition metals.
