Aqua Metals Produces High-Value Minerals at Pilot Plant, Secures Site to Expand Commercial Operations, During First Quarter of 2023

Achievements in low-carbon battery materials by Aqua Metals propel partnership with cathode manufacturer 6K Energy


RENO, Nev., May 4, 2023 (GLOBE NEWSWIRE) -- Aqua Metals, Inc. (NASDAQ: AQMS) (“Aqua Metals" or the "Company”), a pioneer in sustainable lithium battery recycling, today announced financial results and provided a business update for the first quarter ended March 31, 2023.


First Quarter and Recent Highlights:



Announced a non-recurring engineering agreement (NRE) and long-term partnership with 6K Energy to develop next-generation low-carbon, cathode active material (CAM) precursors, to create a domestic supply chain for critical battery materials.



Secured a five-acre campus site, capable of processing more than 20 million pounds of lithium-ion batteries annually, including an existing facility to expand operations.



Recovered high-purity copper, lithium hydroxide, and nickel from black mass using its proprietary LiAquaRefining™ process, establishing the only operational sustainable lithium battery recycling facility in North America.



Strengthened balance sheet with the final $12 million payment received from Comstock Inc. for previously owned property providing sufficient cash balances to execute 2023 plans.  


“This was a quarter of significant operational progress, as we have further proven our pilot-scale facility, and set the stage for the important next phase of our evolution by securing a five-acre campus,” commented Steve Cotton, President and Chief Executive Officer of Aqua Metals. “At our pilot facility, we have successfully recovered a wide-range of high-value, high-purity minerals and finished products, while demonstrating our growing capabilities to potential customers and partners.”


Mr. Cotton continued, “We also secured our next home during the quarter, identifying and securing the ideal site, a five-acre campus in close proximity to leading battery manufacturers. This site, which includes an existing building capable of recycling 3,000 tons of lithium battery ‘black mass’ annually, has the potential to be expanded to 10,000 tons total as our business grows. And to demonstrate our progress, this week we announced a development partnership with 6K Energy and signed a letter of intent to supply their first-of-kind PlusCAM cathode manufacturing facility in Jackson, TN that is planned to produce 13,000 tons of cathode material each year. Upon successful development, this transaction represents a large, multi-million dollar revenue opportunity for Aqua Metals.”




2023 Q1 Financial Results


During the first quarter of 2023, Aqua Metals continued to focus on its ability to recycle metals found in lithium-ion batteries. The Company was not in commercial-scale production during 2022 and, as a result, generated no revenue during the first quarter.


Cost of product sales increased by approximately 7% during the quarter to $1.1 million compared to approximately $1 million in Q1 2022.


Research and development costs included expenditures related to progressing the Lithium-ion battery recycling technology. Research and development cost decreased approximately 19% during the first quarter compared to the same period in 2022, which is what we expected as we move from development to commercialization of our AquaRefining technology.


General and administrative expenses increased approximately 8.7% for the three months ended March 31, 2023, compared to the three months ended March 31, 2022.


For the first quarter 2023, the Company had an operating loss of $4.5 million, compared to an operating loss of $4.3 million for the first quarter of 2022. The net loss for the first quarter of 2023 was $4.6 million, or $(0.06) per basic and diluted share, compared to a net loss of $4.4 million, or $(0.06) per basic and diluted share, for the first quarter of 2022.


As of March 31, 2023, the Company had $3.4 million in cash and cash equivalents. Total cash used in operations for the first three months of 2023 was $2.9 million.
