Aqua Metals Advances Circular Supply Chain Strategy with Sierra ARC Buildout, Commercial Partnerships, and $40M Capital Infusion, Reports First Quarter 2024 Results

Commences $7M Equity Raise, Signs $33M Non-binding Loan Term Sheet with One of the Worlds’ Largest Private Companies, Initiates Strategic Offtake Agreement with 6K Energy

RENO, Nev., May 15, 2024 – Aqua Metals, Inc. (NASDAQ: AQMS), a pioneer in sustainable lithium-ion battery recycling, today reported financial results and provided an operational update, for the first quarter ended March 31, 2024.

First Quarter and Recent Highlights:

● Executed non-binding Term Sheet for up to $33 million loan from one of the largest privately held companies in the world that invests in decarbonization initiatives and closed an additional $7 million in qualifying equity to apply cash to the balance sheet for the loan. Definitive loan Agreement expected by July. This capital infusion is expected to complete Phase One of the Sierra ARC buildout and commissioning in 2024.

● Advanced the multi-part, strategic partnership with 6K Energy and executed an off-take agreement, representing a first-of-its-kind collaboration designed to address the escalating demand for recycling Li-ion batteries by offering manufacturers access to low-cost, low-carbon, domestically produced critical materials – from a recycled source.

● Enhanced Sierra ARC feedstock and offtake diversity and economics through additional agreements with black mass producers.

● Awarded an economic incentive package of approximately $2.2 million that provides partial tax relief toward $35 million worth of equipment, building, and land improvements already underway at the Company’s Sierra AquaRefining™ Campus (ARC).

● Awarded a $371,000 grant from the Department of Energy as a sub-contractor to a critical minerals recovery initiative led by Pennsylvania State University called Alliance for Critical Mineral Extraction and Production from Coal-Based Resources for Vitality Enhancement in Domestic Supply Chains (ACME-REVIVE).

● Won ‘Top Project’ of the year in the prestigious Environment+Energy Leader Awards program for 2024, recognizing Aqua Metals’ innovative technology is driving significant environmental and energy advancements.

“We have made significant progress to date, advancing our commercial partnerships, progressing the buildout of our Sierra ARC Phase One commercial facility, achieving simultaneous 24x5 operations of our pilot plant and fortifying our capitalization to see through our vision,” commented Steve Cotton, President and Chief Executive Officer of Aqua Metals. “We expect to expand and solidify the circular supply chain to provide lower-cost, decarbonized critical materials to create truly sustainable and domestically produced Li-ion batteries. Having already secured a durable supply of black mass to process through our pilot plant, scaling soon for our Sierra ARC, we are now also expanding the circular supply chain by advancing our strategic partnership with 6K Energy. The novel supply agreement will serve as a model for future engagements, creating a fortuitous loop to turn spent batteries into new, low-carbon, critical minerals for manufacturing new batteries right here in the United States.”

“Our continued capitalization also demonstrates the support and resolve of our shareholders and existing and new partners as well as our insiders who all participated,” continued Mr. Cotton. “We have now successfully raised the necessary qualifying equity capital for the expected loan agreement to close by July to complete the first phase of the Sierra ARC and established a new partnership with one of the worlds’ largest privately held companies. We are helping to advance Nevada as a leader in the clean energy innovation economy and are confident in our vision for a sustainable future.”

2024 Q1 Financial Results

During the first quarter of 2024, Aqua Metals focused on continued validation of its pilot plant operation. The pilot plant’s purpose was to test our process for lithium battery recycling and to provide sample production-representative metals produced to multiple announced and unannounced counterparties. As a result, the Company generated no significant revenue in Q1.

Expenses related to plant operations increased by approximately 107% during the quarter to $2.2 million compared to approximately $1.1 million in Q1 2023. The increase in plant operations for the three months ended March 31, 2024, was primarily due to an increase in payroll and payroll related fees of approximately $556,000, as we hired additional staff to operate and train at the pilot facility to be ready to staff the Phase One commercial plant starting in Q3 2024. 

Research and development costs increased approximately 32% during Q1 2024 compared to Q1 2023. General and administrative expenses stayed consistent for the three months ended March 31, 2024, compared to the three months ended March 31, 2023.

For the first quarter 2024, the Company had an operating loss of $5.8 million, compared to an operating loss of $4.5 million for the first quarter of 2023. The net loss for the first quarter of 2024 was $5.8 million, or $(0.05) per basic and diluted share, compared to a net loss of $4.6 million, or $(0.06) per basic and diluted share, for the first quarter of 2023.

As of March 31, 2024, the Company had $8.3 million in cash and cash equivalents. Total cash used in operations for the first three months of 2024 was $4.3 million.
