(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:c74954714">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<sup style="vertical-align:top;line-height:120%;font-size:pt">™</sup>. 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 has been engaged in the pursuit of licensing opportunities within the lead battery recycling marketplace without maintaining and operating a capital-intensive lead recycling facility.</p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"> </p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">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 <em style="font: inherit;">first</em> recycling facility in Nevada’s Tahoe Reno Industrial Center (“TRIC”) in McCarran, Nevada and intended to pursue the development of additional lead acid battery recycling facilities based on the Company’s AquaRefining technology, likely through licensing or joint development arrangements. 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", Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"> </p> <p style="font-family: "Times New Roman", Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">On the evening of <em style="font: inherit;"> November 29, 2019, </em>a fire occurred in the AquaRefining area of the facility. The fire and related intense heat and smoke caused significant damage to a material amount of equipment in the AquaRefinery area, including all <em style="font: inherit;">16</em> AquaRefining modules, electrical and tank infrastructure, steel superstructure, control wiring and other supporting infrastructure. Following the fire, the Company adopted a capital light strategy designed to optimize shareholder value by focusing on equipment supply and licensing opportunities, which have always been a core part of the Company’s business plans. On <em style="font: inherit;"> July 1, 2021, </em>the Company signed a Letter of Intent (LOI) with ACME Metal Enterprise Co., Ltd. (ACME) to deploy and license AquaRefining equipment at its facility in Keelung, Taiwan. The Company believes the path of licensing our technology has the potential to maximize shareholder value in that it could be far less capital intensive than a rebuild and could be funded solely or primarily from a combination of cash on hand, insurance proceeds and asset dispositions.</p> <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;"> </p>
