(the “Company”) was incorporated in Delaware and commenced operations on <em style="font: inherit;"> June 20, 2014 (</em>inception). On <em style="font: inherit;"> January 27, 2015, </em>the Company formed <span style="-sec-ix-hidden:c80862082">two</span> wholly owned subsidiaries, Aqua Metals Reno, Inc. (“AMR”) and Aqua Metals Operations, Inc. (collectively, the “Subsidiaries”), both incorporated in Delaware. The Company is engaged in the business of equipment supply, technology licensing and related services for recycling lead through a novel, proprietary and patented process the Company developed and named AquaRefining™. Prior to <em style="font: inherit;"> November 29, 2019, </em>the Company was engaged in the business of lead recycling through its patented and patent pending AquaRefining technology. Following a fire at its lead recycling facility on <em style="font: inherit;"> November 29, 2019, </em>the Company's business model has transitioned to a focus on global licensing opportunities to incorporate AquaRefining in the recycling industry. </p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt; text-indent: 0pt; background-color: rgba(0, 0, 0, 0); color: rgb(0, 0, 0);">Unlike smelting, AquaRefining is a room temperature, water-based process that emits less pollution than smelting, the traditional method of lead recycling. The Company built its recycling facility in Nevada’s Tahoe Reno Industrial Center (“TRIC”) in McCarran, Nevada. The Company commenced the shipment of products for sale, consisting of lead compounds and plastics in <em style="font: inherit;"> April 2017, </em>and through <em style="font: inherit;"> March 31, 2018 </em>substantially all revenue was derived from the sale of lead compounds and plastics. In <em style="font: inherit;"> April 2018, </em>the Company commenced the limited production of lead bullion, including AquaRefined lead. In <em style="font: inherit;"> July 2018, </em>the Company commenced the sale of pure AquaRefined lead in the form of <em style="font: inherit;">two</em> tonne blocks and in <em style="font: inherit;"> October 2018, </em>the Company commenced the sale of AquaRefined lead in the form of battery manufacturing ready ingots. In <em style="font: inherit;"> November 2018, </em>the Company received official vendor certification from Clarios for its AquaRefined lead and, in <em style="font: inherit;"> December 2018, </em>the Company commenced shipments directly to Clarios owned and partner battery manufacturing facilities. In <em style="font: inherit;">2019,</em> the Company operated its demonstration AquaRefinery at commercial quantity production levels and produced over <em style="font: inherit;">35,000</em> AquaRefined ingots by operating the AquaRefinery <em style="font: inherit;">24</em> hours a day and <em style="font: inherit;">seven</em> days a week for sustained periods of time. The AquaRefining Aqualyzers produced at or above the target <em style="font: inherit;">100</em> Kg/Hr of production throughput per module of <em style="font: inherit;">six</em> Aqualyzers or ~ <em style="font: inherit;">16</em>-<em style="font: inherit;">17</em> Kg/Hr per Aqualyzer and ran sustained endurance runs for over <em style="font: inherit;">one</em> month several times.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt; text-indent: 0pt; background-color: rgba(0, 0, 0, 0); color: rgb(0, 0, 0);">During the <em style="font: inherit;">first</em> half of <em style="font: inherit;">2020,</em> we successfully performed test runs on the <em style="font: inherit;">first</em> and <em style="font: inherit;">second</em> iterations of our Aqualyzer as part of our <em style="font: inherit;">V1.25L</em> program. The program consists of <em style="font: inherit;">three</em> iterations that are classified as <em style="font: inherit;">V1.25a,</em> <em style="font: inherit;">V1.25b</em> and the final iteration, <em style="font: inherit;">V1.25L.</em> During the <em style="font: inherit;">fourth</em> quarter of <em style="font: inherit;">2020,</em> we completed our <em style="font: inherit;">V1.25L</em> Aqualyzer program on time and under budget, achieving lead production that is <em style="font: inherit;">100%</em> greater compared to the <em style="font: inherit;">V1.0</em> Aqualyzer deployed at the AquaRefinery during commercial production in <em style="font: inherit;">2018</em> and <em style="font: inherit;">2019.</em> In <em style="font: inherit;"> August 2021, </em>we announced the completion of the <em style="font: inherit;">V1.5</em> Aqualyzer.

The increase in throughput results in a reduction of more than <em style="font: inherit;">60%</em> in the number of Aqualyzers needed for equivalent lead production delivered by the <em style="font: inherit;">V1.0</em> model, reducing capital and labor and footprint requirements.

In <em style="font: inherit;"> August 2021, </em>we announced that we had established an Innovation Center focused on applying our proven technology to lithium-ion battery recycling research and development and prototype system activities. Our strategic decision to apply our proven clean, closed-loop hydrometallurgical and electro-chemical recycling experience to lithium-ion battery recycling is designed to meet the growing demand for critical metals driven by the global transition to electric vehicles, growth in Internet data centers, and alternative energy applications including solar, wind, and grid-scale storage. </p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify; text-indent: 0pt; background-color: rgba(0, 0, 0, 0); color: rgb(0, 0, 0);">In <em style="font: inherit;"> November 2021, </em>Aqua Metals and LINICO signed a collaboration agreement which sets the parameters for future research and development cooperation, as both companies’ expand into lithium-ion battery recycling and advance our technologies designed to recycle lithium-ion batteries cost-effectively and sustainably. Aqua Metals and LINICO plan to source the necessary lithium-ion feedstock from battery manufacturing scrap and end-of-life cells from various sources, including electric vehicle battery suppliers interested in participating in the eco-network the <em style="font: inherit;">two</em> companies announced in <em style="font: inherit;">2021.</em> LINICO will process the feedstock into high-quality black mass utilizing its proprietary process.

Our capital light business strategy is designed to optimize shareholder value by focusing on equipment supply and licensing opportunities, which have always been a core part of our business plans. On <em style="font: inherit;"> July 29, 2021, </em>the Company signed a Definitive Agreement with ACME Metal Enterprise Co., Ltd. (ACME) to deploy AquaRefining equipment at its facility in Keelung, Taiwan. We believe the path of licensing our technology has the potential to maximize shareholder value in that it could be far less capital intensive than our operation of <em style="font: inherit;">one</em> or more recycling facilities and could be funded in part from a combination of cash on hand and asset dispositions.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;"><span style="text-decoration: underline; ">Liquidity and Management Plans</span></p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 18pt; text-align: justify; text-indent: 27pt;"> </p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt; text-align: justify;">The Company generated revenues of $0.2 million and $0.1 million during the years ended <em style="font: inherit;"> December 31, 2021 </em>and <em style="font: inherit;"> December 31, 2020</em>, respectively.
