Second Quarter and Recent Highlights:

Aqua Metals has successfully recovered all the high-value metals from used lithium-ion batteries, including high purity lithium hydroxide, copper, nickel, cobalt, and manganese dioxide.
Proved at bench scale our clean and economical metals recycling process.
Initiated the deployment of our first lithium-ion recycling pilot operation at our Innovation Center in Tahoe-Reno Industrial Center, which will begin operations later this year.
Signed a Letter of Intent with Dragonfly Energy Corporation, a leader in lithium-ion deep cycle batteries, Dragonfly would purchase commercial quantities of lithium hydroxide for ongoing development of solid state lithium-ion battery technologies and future manufacturing activities
AquaRefining equipment arrived at our first international partner, ACME Metals Enterprise in Taiwan, with commissioning expected later in Q3.
100% of our operations, including offices and the Innovation Center, are and will be 100% powered by renewable energy, reinforcing Aqua Metals' commitment to the environment.

RENO, Nev., July 21, 2022 (GLOBE NEWSWIRE) -- Aqua Metals, Inc. (NASDAQ:AQMS) ("Aqua Metals" or the "Company"), which is reinventing metals recycling with its AquaRefining™ technology, today announced results for the second quarter ended June 30, 2022.

"We are developing what we believe is the cleanest and most cost-efficient lithium-ion battery recycling solution that is fundamentally non-polluting, offering a competitive superior metals recycling solution," commented Steve Cotton, President and Chief Executive Officer. "Our progress in the second quarter reinforces our confidence in our path to revenue, through multiple financial strategies and partnerships designed to rapidly grow our business."

The research team at the Aqua Metals Innovation Center in the Tahoe-Reno Industrial Center is continuing to advance research and development initiatives to further differentiate the Company's technology. During the quarter, the Company announced that it had plated high purity cobalt and produced manganese dioxide from lithium-ion battery black mass. With the production of these two materials, the Company has successfully recovered all the high-value metals from used lithium-ion batteries, including lithium hydroxide, copper, and nickel, proving at bench scale the clean and economical metals recycling process. Based on the successful results to date, the Company has initiated the deployment of a lithium-ion battery recycling pilot at its Innovation Center that will be installed, commissioned, and begin operations later this year. Aqua Metals also announced it signed a Letter of Intent to partner with Dragonfly Energy, an innovative company that recognizes AquaRefining's superior, high-value Li recovery approach with the lowest environmental footprint of any technology currently under development.

During the second quarter of 2022, the shipments of our third-generation (version 1.5) PB AquaRefining Aqualyzers arrived at ACME Metals. Installation and commissioning will begin in Q3 of 2022

2022 Q2 Financial Results

During the second quarter of 2022, Aqua Metals continued to focus on research and development activities to enhance its ability to recycle metals found in lithium-ion batteries and the preparation of commissioning of the ACME Metals' facility. The Company was not in commercial production during 2022 and, as a result, generated no significant revenue during the quarter.

Cost of product sales decreased by approximately 51% during the quarter to $1.0 million compared to $2.1 million in Q2 2021. The cost of product sales decreased during Q2 2022 due to wrapping up the plant clean-up project.

Research and development costs included expenditures related to improving the Lithium-ion battery AquaRefining technology. Research and development increased approximately 196% during the second quarter compared to the three months ended June 30, 2021. Research and development is a crucial part of our business strategy and includes our focus on continuous product improvement of the Company's proprietary technology for LAB recycling and further advancing our development related to the application of AquaRefining to recycling lithium-ion batteries. These costs also include expenditures toward building our pilot plant, which is expected to be commissioned later this year.

General and administrative expenses increased approximately 12% for the three months ended June 20, 2022, compared to the three months ended June 30, 2021. Increases in general and administrative expenses included changes in stock-based compensation and an increase in professional fees.

For the second quarter of 2022, the Company had an operating loss of $4.0 million, compared to an operating loss of $4.4 million for the second quarter of 2021. The net loss for the second quarter of 2022 was $3.2 million, or $0.04 per basic and diluted share, compared to a net loss of $8.0 million, or $0.12 per basic and diluted share, for the second quarter of 2021.

As of June 30, 2022, the Company had $6.4 million in cash and cash equivalents.
