   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">Aqua Metals, Inc. (the &#x201c;Company&#x201d;) 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:c72479676">two</span> wholly-owned subsidiaries, Aqua Metals Reno, Inc. (&#x201c;AMR&#x201d;) and Aqua Metals Operations, Inc. (collectively, the &#x201c;Subsidiaries&#x201d;), 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">&#x2122;</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: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">&#xa0;</p>
   <p style="font-family: &quot;Times New Roman&quot;, 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&#x2019;s Tahoe Reno Industrial Center (&#x201c;TRIC&#x201d;) in McCarran, Nevada and intended to pursue the development of additional lead acid battery recycling facilities based on the Company&#x2019;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: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">&#xa0;</p>
   <p style="font-family: &quot;Times New Roman&quot;, 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&#x2019;s business plans. The Company believes this path 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: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">Aqua Metals (NASDAQ: <span style="text-decoration: underline; ">AQMS</span>) is engaged in the business of equipment supply, technology licensing and related services for recycling lead through a novel, proprietary and patented process we developed and named AquaRefining<sup style="vertical-align:top;line-height:120%;font-size:pt">&#x2122;</sup>. AquaRefining is a room temperature, water and organic acid-based process that greatly reduces environmental emissions. Lead is a globally traded commodity with a worldwide market value in excess of $20 billion. We believe our suite of patented and patent pending AquaRefining technologies will allow the lead-acid battery industry to simultaneously improve the environmental impact of lead recycling and scale recycling production to meet demand. Furthermore, our AquaRefining technologies result in high purity lead. We were formed as a Delaware corporation on June 20, 2014 and since our formation, we have focused our efforts on the development and testing of our AquaRefining process, the construction of our initial lead acid battery, or LAB, recycling facility at the Tahoe Reno Industrial Center, or TRIC, located in McCarran, Nevada and commercializing the AquaRefining process.</p>
  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">&#xa0;</p>
  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">We completed the development of our first LAB recycling facility at Nevada&#x2019;s Tahoe Reno Industrial Center, or TRIC, in McCarran, Nevada and commenced production of battery breaking and limited operations during the first quarter of 2017. In April 2017, we commenced the shipment of products for sale, consisting of lead compounds as well as plastics. In April 2018, we commenced the limited production of lead bullion, including AquaRefined lead. In July 2018, we commenced the sale of pure AquaRefined lead in the form of two tonne blocks and, in October 2018, we commenced the sale of AquaRefined lead in the form of battery manufacturing ready ingots. In November 2018, we received official vendor certification from Clarios for our AquaRefined lead and in December 2018, we commenced shipments directly to Clarios owned and partner battery manufacturing facilities. In 2019, we operated our demonstration AquaRefinery at commercial quantity production levels and produced over 35,000 AquaRefined ingots by operating the AquaRefinery 24 hours a day and 7 days a week for sustained periods of time. The AquaRefining Aqualyzers&#xa0;produced at or above the target 100 Kg/Hr of production throughput per module of six Aqualyzers or ~16-17 Kg/Hr per Aqualyzer and ran sustained endurance runs for over one month several times.</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">In order to expand the demonstration AquaRefinery to its full capacity, we chose to idle the AquaRefinery beginning in September 2019 to facilitate contracting work required to increase the plant capacity planned for late 2019 or early 2020. On the evening of November 29, 2019, a fire occurred in the AquaRefining area of the recycling facility at TRIC. The cause of the fire was not due to the technology or process of AquaRefining but rather to contracting activities. The fire and related intense heat and smoke caused significant damage to a material amount of equipment in the AquaRefinery area, including all 16 AquaRefining modules, electrical and tank infrastructure, steel superstructure, control wiring and other supporting infrastructure. The floor to ceiling firewall between the AquaRefining area and the rest of the plant isolated the worst of the damage to the AquaRefining area. The firewall also appears to have spared material damage to much of the key front-end process equipment, such as the battery breaker/separation system, concentrate production area, kettles and ingot casting, water treatment and recovery and other important areas of the plant. The administrative office area also remained intact.</p>
  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">&#xa0;</p>
  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">As of March 31, 2021, we have received approximately $23.6 million of insurance proceeds&#xa0;from our insurance carriers. Subsequent to quarter end, we received an initial payment of $1.4 million towards our business interruption insurance claim from the third layer of insurance, completing the total amount due from this insurance layer. As of the date of this report, we expect to receive $2.0 million from the fourth and final insurance layer.&#xa0;The fourth layer has a payment range of up to $25 million. Future insurance proceeds from the business interruption and property claims are anticipated based on current estimates and calculations. As of the date of this report, the Company has now collected a total of $25.0 million of insurance proceeds related to the November 2019 fire event.&#xa0;We intend to vigorously pursue receipt of insurance proceeds to satisfy in full all of our property, casualty and business interruption losses, subject to the coverage limits. Property and equipment on our balance sheet as of March&#xa0;31, 2021&#xa0;that were not affected by the fire total approximately $24.7&#xa0;million&#xa0;in book value, including the battery breaker, melting kettles, kiln, filter presses, mixing and storage tanks, water recovery system and the building infrastructure plus the land.&#xa0;</p>
  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">&#xa0;</p>
  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">During the first half of 2020, we successfully performed test runs on the first and second iterations of our&#xa0;Aqualyzer as part of our V1.25L program. The program consists of three iterations that are classified as V1.25a, V1.25b and the final iteration, V1.25L, the latter of which will be used to create the AquaRefining Aqualyzer package for our equipment supply and licensing offerings. During the fourth quarter of 2020, we completed our V1.25L Aqualyzer program on time and under budget, achieving lead production that is 100% greater compared to the V1.0 Aqualyzer deployed at the AquaRefinery during commercial production in 2018 and 2019. The Company previously guided a 20% increase of throughput, yet the V.125L Aqualyzer surpassed that guidance by 500%. The V1.25L program concluded with a multi-day 24/7 endurance run that ended on December 24, 2020. These results should positively impact capital and operating expenses for our future equipment supply and licensee customers. The doubling of throughput results in a 50% reduction in the number of Aqualyzers needed for equivalent lead production. V1.25L also has a lower build cost and reduced assembly time compared to the V1.0 Aqualyzer, which correlates to a 50% decrease in capital expenditures for Aqua Metals equipment installations. In addition, Aqualyzer operating expenses have been reduced by greater than 60% compared to the V1.0 Aqualyzer, with the combined impact of improvements in automation and increased throughput. The current design has a single button start and stop functionality with no manual interaction required during operation, along with automated maintenance capability. The 60% reduction in operating expenses and 50% reduction in capital expenditures greatly exceeds the targets that were set in early 2020.</p>

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. We believe this path has the potential to maximize shareholder value in that it could be far less capital intensive than a plant rebuild.</p>

  <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:left;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 15pt;text-indent:36pt;">We have been engaged in the pursuit of a capital light strategy that is based on the pursuit of licensing opportunities within the lead battery recycling marketplace without maintaining and operating a capital-intensive lead recycling facility. We believe our capital light business strategy will require less space and less equipment and focus on the needs of our future licensees. We have accelerated our capital light business strategy, designed to optimize shareholder value by focusing on equipment supply and licensing opportunities, which have always been a core part of our business plans. We believe this path has the potential to maximize shareholder value as we focus on the shift to an equipment plus services supplier and licensor of our technology.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 15pt;text-indent:36pt;">Our capital light strategy is consistent with our long-held business strategy and objectives. When we designed and developed TRIC in 2016, we did so at a time when our business model assumed that TRIC would be the first of many LAB recycling facilities owned and operated by us. Commencing in 2017, we began to shift our focus away from the development of additional Company-owned LAB recycling facilities and towards the licensing of our AquaRefining technology to partners engaged in LAB recycling. We continued to develop TRIC as a LAB recycling facility for purposes of further demonstrating AquaRefining on a commercial scale. However, as a result of the 2019 fire and our high costs of capital we believe that the cost of restoring TRIC to its pre-fire state would not be the best use of our available and projected cash and that we may be able to achieve the benefits of operating our facility at TRIC in its pre-fire state, namely the development and demonstration of the licensing ready iteration of our AquaRefining technologies, which we call Version 1.25L. During 2020, we completed the V1.25L Aqualyzer program and achieved a 100% improvement in lead production throughput, in addition to improved equipment and operating costs. We believe that our results of operations and improvements to our Aqualyzers, to date, can demonstrate to potential licensees the value proposition of our AquaRefining technologies. We believe that our AquaRefining technology would be a commercially attractive valuable proposition in the hands of battery recyclers, who typically have access to lower cost feedstock and ability to process all materials on site through a furnace.</p>
  <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#xa0;</p>
  <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt 0pt 0pt 15pt;text-indent:36pt;">Our capital light strategy also includes an expansion into lithium-ion battery recycling by investing in&#xa0;LINICO Corporation&#xa0;(&#x201c;LiNiCo&#x201d;). The Company and LiNiCo reached a lease-to-buy agreement for the Aqua Metals' AquaRefining facility. Aqua Metals has committed a $1.5 million investment, paid in Aqua Metals shares and $232,000 in cash, for an ownership share in LiNiCo of approximately 9%, as part of our&#xa0;strategy to strengthen growth by potentially applying AquaRefining&#x2122; intellectual property to lithium-ion battery recycling while meeting its lead recycling commercial guidance. We believe that expanding our patented AquaRefining hydrometallurgical approach to recycling the high-value metals of lithium-ion batteries is a smart, long-term strategy for Aqua Metals and the creation of shareholder value.</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">As mentioned previously, historical product sales have consisted of high-purity lead from our AquaRefining process as well as lead bullion, lead compounds and plastics. Except for nominal sales of inventory in the first quarter&#xa0;of 2020, we did not generate revenue for either the&#xa0;three months ended March 31, 2021&#xa0;or the&#xa0;three months ended March 31, 2020&#xa0;as there has&#xa0;been no significant production subsequent to the fire that occurred during the fourth quarter of 2019. The plant will not be in production during 2021&#xa0;except for the operation and testing of our improved Aqualyzers as part of the V1.25 program.</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">Cost of product sales includes raw materials, supplies and related costs, salaries and benefits, consulting and outside services costs, depreciation and amortization costs and insurance, travel and overhead costs. Cost of product sales increased approximately 11%&#xa0;for the three months ended March 31, 2021&#xa0;as compared to the three months ended March 31, 2020. The increase in cost of product sales was a result of plant clean-up costs, in preparation for&#xa0;the lease and eventual sale of the facility.&#xa0;&#xa0;&#xa0; &#xa0; &#xa0;</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">Research and development cost included expenditures related to the improvement of the AquaRefining technology related to our lead recycling process and initial development of our lithium recycling process. During the three months ended March 31, 2021, research and development costs increased $47,000 or 19% over the comparable period&#xa0;in 2020. This modest increase was driven by the Company's&#xa0;efforts to maintain and advance our proprietary AquaRefining technology.&#xa0;&#xa0;</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">Insurance proceeds net of related expenses resulted from collection and payment activity that began in 2020 following the November&#xa0;2019 fire. The decrease is due to timing of insurance payments and associated fire clean-up expenses. One of the Company's two PPP loan's for $131,000, received in May of 2020, was forgiven during the&#xa0;three months ended March 31, 2021.&#xa0;The decrease in interest expense for the first quarter of 2021 compared to the first quarter of 2020 resulted from the retirement of the Veritex loan during the fourth quarter of 2020. Interest income decreased for the three months ended March 31, 2021 compared to the same period in 2020, primarily due to lower bank interest rates during the period.</p>

We intend to acquire the necessary capital though the recovery of any remaining insurance proceeds on our fire related claims,&#xa0;the possible sale of certain equipment and assets at TRIC, and the collection of funds from the sale of our plant. However, there can be no assurance that such funds will be available. If needed, we may seek funding through the sale of equity or debt financing, including the sale of our common shares through our current at-the-market offering. Funding that includes the sale of our equity may be dilutive. If such financing is not available on satisfactory terms, we may be unable to further pursue our business plan and we may be unable to continue operations.&#xa0;</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">Beginning on December 15, 2017, three purported class action lawsuits were filed in the United Stated District Court for the Northern District California against us, Stephen Clarke, Thomas Murphy and Mark Weinswig. On March 23, 2018, the cases were consolidated under the caption <i>In Re: Aqua Metals, Inc. Securities Litigation </i>Case No 3:17-cv-07142. On May 23, 2018, the Court appointed lead plaintiffs and approved counsel for the lead plaintiffs. On July 20, 2018, the lead plaintiffs filed a consolidated amended complaint (&#x201c;Amended Complaint&#x201d;), on behalf of a class of persons who purchased our securities between May 19, 2016 and November 9, 2017, against us, Stephen Clarke, Thomas Murphy and Selwyn Mould. The Amended Complaint alleges the defendants made false and misleading statements concerning our lead recycling operations and conducted deceptive site visits&#xa0;in violation of Section 10(b) of the Securities Exchange Act of 1934 (&#x201c;Exchange Act&#x201d;) and Rule 10b-5 promulgated thereunder and seeks to hold the individual defendants as control persons pursuant to Section 20(a) of the Exchange Act. The Amended Complaint also alleges a violation of Section 11 of the Securities Act of 1933 (&#x201c;Securities Act&#x201d;) based on alleged false and misleading statements concerning our lead recycling operations contained in, or incorporated by reference in, our Registration Statement on Form S-3 filed in connection with our November 2016 public offering. That claim is asserted on behalf of a class of persons who purchased shares pursuant to, or that are traceable to, that Registration Statement. The Amended Complaint seeks to hold the individual defendants liable as control persons pursuant to Section 15 of the Securities Act. The Amended Complaint seeks unspecified damages and plaintiffs&#x2019; attorneys&#x2019; fees and costs. On September 18, 2018, the defendants filed a motion to dismiss the Amended Complaint in its entirety and the plaintiff subsequently filed its opposition to the motion. In an order dated August 14, 2019, the Court granted in part, and denied in part, the defendants&#x2019; motion to dismiss. The Court granted the motion to dismiss the Securities Act Section 11 claim and the Exchange Act Section 10(b) and Rule 10b-5 claim based on alleged false and misleading statements and gave the plaintiffs leave to amend to address the deficiencies. The Court denied the motion to dismiss the Exchange Act Section 10(b) and Rule 10b-5 claims regarding site visits. On September 20, 2019, the plaintiffs filed a Second Amended Complaint that dropped the Securities Act Section 11 claim but otherwise alleges the same claims as were alleged previously. The Second Amended Complaint seeks unspecified damages and plaintiffs&#x2019; attorneys&#x2019; fees and costs. On November 1, 2019, the defendants filed a motion to dismiss the Exchange Act Section 10(b) and Rule 10b-5 claims in the Second Amended Complaint based on alleged false and misleading statements, but not the claims regarding site visits. In an order dated November 16, 2020, the Court granted the motion and dismissed with prejudice the claim based on alleged false and misleading statements. We deny that the claims in the Second Amended Complaint have any merit and we intend to vigorously defend the action.</p>

Clarke, Selwyn Mould, Thomas Murphy, Mark Weinswig, Vincent DiVito, Mark Slade and Mark Stevenson. On May 3, 2018, the cases were consolidated under the caption <i>In re Aqua Metals, Inc. Stockholder Derivative Litigation</i>, Case No. 1:18-cv-00201-LPS (D. Del.). The complaints were filed by persons claiming to be stockholders of Aqua Metals and generally allege that certain of our officers and directors breached their fiduciary duties to us by violating the federal securities laws and exposing us to possible financial liability. The complaints seek unspecified damages and plaintiffs&#x2019; attorneys&#x2019; fees and costs. The parties have entered into a stipulation staying the action. The individual defendants deny that the claims in the shareholder derivative action have any merit and intend to vigorously defend the action.</p>

  <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 36pt;">When we designed and developed TRIC, we did so at a time when our business model assumed that TRIC would be the first of many LAB recycling facilities owned and operated by us. Commencing in 2017, we began to shift our focus away from the development of additional Company-owned LAB recycling facilities and towards the licensing of our AquaRefining technology to partners engaged in LAB recycling. We continued to develop TRIC as a LAB recycling facility for purposes of demonstrating AquaRefining on a commercial scale. However, as a result of the fire and our high costs of capital, we decided that the cost of restoring TRIC to its pre-fire state would not be the best use of our available cash and that we may be able to achieve the benefits of operating 16 AquaRefining modules, namely the demonstration of the scalability of our AquaRefining technologies, through a less costly commercialization program. Commencing in early 2020, we began to focus on licensing opportunities within the $20+ billion lead battery recycling marketplace. We believe this path is far less capital intensive than a rebuild of TRIC to its pre-fire state and we believe this plan could be funded solely or primarily from cash on hand plus any further insurance proceeds and asset disposition of the AquaRefinery. However, there can be no assurance that our revised business model will be successful or that we will acquire the additional capital sufficient to fund our revised business plan.</p>

From inception through&#xa0;March 31, 2021, we generated a total of $11.5 million&#xa0;of revenue, all of which was derived primarily from the sale of lead compounds and plastics and, to a lesser extent, the sale of lead bullion and AquaRefined lead. To date, our operations have primarily consisted of the development and testing and limited operations of our AquaRefining process, the construction of our initial LAB recycling facility at TRIC, the continuing development of our LAB recycling operations at TRIC and limited revenue producing operations as we brought those LAB recycling operations online. As a result of the November 2019 fire at TRIC, we have suspended all plant-based revenue producing operations and have shifted our business model to focus exclusively on the licensing of our AquaRefining technology to partners engaged in LAB recycling.&#xa0;As of the date of this report, we are unable to estimate when we expect to commence&#xa0;any meaningful commercial or revenue producing operations from our licensing model. Our limited operating history makes it difficult for potential investors to evaluate our technology or prospective operations. As an early stage company, we are subject to all the risks inherent in the initial organization, financing, expenditures, complications and delays in a new business, including, without limitation:</p>

We may not be successful in defending such litigation and may not be able to procure any required royalty or license agreements on acceptable terms or at all.</p>

In February 2017, we entered into a series of agreements with Clarios, including an equipment supply agreement pursuant to which, among other things, we agreed to work with Clarios on the development of a program for the conversion of Clarios and certain strategic partners of Clarios&#x2019; existing lead smelters throughout North and South America, China and Europe to a lead recycling process utilizing our AquaRefining technology and equipment, know-how and services. The equipment supply agreement discusses the development of the conversion program in general terms and contemplates that the parties will enter into a definitive development program agreement that is based on the general terms set forth in the equipment supply agreement and provides more detailed terms and conditions, including the economic obligations and rights of each party. We have agreed not to license our AquaRefining technology and equipment to third parties in the aforementioned regions until such time as we and Clarios have agreed on certain matters relating to the initial conversion of a Clarios facility. In June 2019, we entered into an agreement with Clarios to amend the equipment supply agreement pursuant to which we have agreed to use good faith, commercial best-efforts to conclude the discussion and negotiation of, and enter into, a development program agreement no later than the 90th day following our satisfaction of certain performance criteria agreed upon by Clarios and us, however those performance conditions were based on the operation of 16 AquaRefining modules at TRIC, which is unlikely. If we are unable to agree with Clarios on revised performance standards, we may be unable to sell AquaRefining equipment or license our AquaRefining technology to third-parties until the expiration of the Equipment Supply Agreement in June 2021 or the agreement&#x2019;s earlier termination. There can be no assurance that we will be able to negotiate and conclude a definitive development program agreement with Clarios on commercially reasonable terms, or at all.</p>

The acquired battery group assets now operates under the name Clarios.&#xa0;The agreements and proposed business projects between us and Johnson Controls Battery Group, Inc. (collectively, the "Aqua Metals Collaboration") are now under the control of Clarios, and that certain members of the former management of Johnson Controls Battery Group, Inc. are now&#xa0;employed in similar capacities by Clarios. We have also been advised that Clarios and Brookfield Business Partners L.P. have expressed their interest in continuing the Aqua Metals Collaboration initiated by us and Johnson Controls Battery Group, Inc. Although there can be no assurance that Clarios currently has, and/or will maintain, the same level of interest in our joint collaboration as its predecessor, as Clarios could, for example, no longer have an interest in our technologies or have competing priorities, we currently have no reason to believe that Clarios and Brookfield Business Partners L.P. have lost interest. In addition, the change of control of the battery group may cause disruptions and distractions that adversely affect its ability to further the Aqua Metals Collaboration. For these and other reasons, Johnson Controls&#x2019; sale of its battery group assets to Brookfield Business Partners L.P. could possibly have a material adverse effect on the Aqua Metals Collaboration.</p>

We believe that the market price of our principal product, recycled lead, is relatively volatile and reacts to general global economic conditions. Lead prices decreased from $2,139&#xa0;per tonne on May 5, 2015 to a low of $1,554&#xa0;per tonne on November 23, 2015 because of fluctuations in the market. Lead price per tonne was approximately $1,775 at the end of March 2021. Our business will be highly dependent on the economic and market conditions in each of the geographic areas in which we operate. These conditions affect our business by reducing the demand for LABs and decreasing the price of lead in times of economic downturn and increasing the price of used LABs in times of increasing demand of LABs and recycled lead. There can be no assurance that global economic conditions will not negatively impact our liquidity, growth prospects and results of operations.</p>

(the &#x201c;Company&#x201d;) was incorporated in Delaware and commenced operations on &lt;em style="font: inherit;"&gt; June 20, 2014 (&lt;/em&gt;inception). On &lt;em style="font: inherit;"&gt; January 27, 2015, &lt;/em&gt;the Company formed &lt;span style="-sec-ix-hidden:c72479676"&gt;two&lt;/span&gt; wholly-owned subsidiaries, Aqua Metals Reno, Inc. (&#x201c;AMR&#x201d;) and Aqua Metals Operations, Inc. (collectively, the &#x201c;Subsidiaries&#x201d;), 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&lt;sup style="vertical-align:top;line-height:120%;font-size:pt"&gt;&#x2122;&lt;/sup&gt;. Prior to &lt;em style="font: inherit;"&gt; November 29, 2019, &lt;/em&gt;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 &lt;em style="font: inherit;"&gt; November 29, 2019, &lt;/em&gt;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.&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"&gt;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 &lt;em style="font: inherit;"&gt;first&lt;/em&gt; recycling facility in Nevada&#x2019;s Tahoe Reno Industrial Center (&#x201c;TRIC&#x201d;) in McCarran, Nevada and intended to pursue the development of additional lead acid battery recycling facilities based on the Company&#x2019;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 &lt;em style="font: inherit;"&gt; April 2017, &lt;/em&gt;and through &lt;em style="font: inherit;"&gt; March 31, 2018 &lt;/em&gt;substantially all revenue was derived from the sale of lead compounds and plastics. In &lt;em style="font: inherit;"&gt; April 2018, &lt;/em&gt;the Company commenced the limited production of lead bullion, including AquaRefined lead. In &lt;em style="font: inherit;"&gt; July 2018, &lt;/em&gt;the Company commenced the sale of pure AquaRefined lead in the form of &lt;em style="font: inherit;"&gt;two&lt;/em&gt; tonne blocks and in &lt;em style="font: inherit;"&gt; October 2018, &lt;/em&gt;the Company commenced the sale of AquaRefined lead in the form of battery manufacturing ready ingots. In &lt;em style="font: inherit;"&gt; November 2018, &lt;/em&gt;the Company received official vendor certification from Clarios for its AquaRefined lead and, in &lt;em style="font: inherit;"&gt; December 2018, &lt;/em&gt;the Company commenced shipments directly to Clarios owned and partner battery manufacturing facilities. In &lt;em style="font: inherit;"&gt;2019,&lt;/em&gt; the Company operated its demonstration AquaRefinery at commercial quantity production levels and produced over &lt;em style="font: inherit;"&gt;35,000&lt;/em&gt; AquaRefined ingots by operating the AquaRefinery &lt;em style="font: inherit;"&gt;24&lt;/em&gt; hours a day and &lt;em style="font: inherit;"&gt;seven&lt;/em&gt; days a week for sustained periods of time. The AquaRefining Aqualyzers produced at or above the target &lt;em style="font: inherit;"&gt;100&lt;/em&gt; Kg/Hr of production throughput per module of &lt;em style="font: inherit;"&gt;six&lt;/em&gt; Aqualyzers or ~ &lt;em style="font: inherit;"&gt;16&lt;/em&gt;-&lt;em style="font: inherit;"&gt;17&lt;/em&gt; Kg/Hr per Aqualyzer and ran sustained endurance runs for over &lt;em style="font: inherit;"&gt;one&lt;/em&gt; month several times.&lt;/p&gt;

   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"&gt;On the evening of &lt;em style="font: inherit;"&gt; November 29, 2019, &lt;/em&gt;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 &lt;em style="font: inherit;"&gt;16&lt;/em&gt; 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&#x2019;s business plans. The Company believes this path 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.&lt;/p&gt;

Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, the valuation of conversion features of convertible debt, valuation allowances for deferred tax assets, the determination of fair value of estimated asset retirement obligations, the determination of stock option expense and the determination of the fair value of stock warrants issued.

Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following shares underlying outstanding convertible notes, stock options, RSUs and warrants to purchase common stock were antidilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive securities computation for the&#160;&lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; March 31&lt;/em&gt;, as indicated below.&lt;/p&gt; &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;

Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following shares underlying outstanding convertible notes, stock options, RSUs and warrants to purchase common stock were antidilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive securities computation for the&#160;&lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; March 31&lt;/em&gt;, as indicated below.&lt;/p&gt; &lt;p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;"&gt;&#160;&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;"&gt;The Company accounted for the LiNiCo investment under ASC &lt;em style="font: inherit;"&gt;321,&lt;/em&gt; Investments-Equity Securities, using the measurement alternative of recording at cost as the investment in LiNiCo doesn&#x2019;t have a readily determinable fair value.&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;"&gt;The LiNiCo Series A Preferred Stock is senior to all other capital stock of LiNiCo with regard to dividends and distributions upon liquidation, dissolution and sale of the company. Each share of LiNiCo Series A Preferred Stock is entitled to &lt;em style="font: inherit;"&gt;one&lt;/em&gt; vote per share and votes with the common stock on all matters, subject to certain protective provisions that require the approval of the holders of the Series A Preferred Stock voting as a class. The Series A Preferred Stock accrues a cumulative dividend of 8% per annum on the original stated value of $1,000 per share, and all accrued and unpaid dividends on the Series A Preferred Stock must be paid in full prior to the payment of any dividends on any other shares of LiNiCo capital stock. In the event of any liquidation or dissolution of LiNiCo, which would include a sale of LiNiCo, the holders of the Series A Preferred Stock shall receive the return of their stated value of &lt;em style="font: inherit;"&gt;$1,000&lt;/em&gt; per share plus all accrued and unpaid dividends prior to any distribution to the holders of any other capital stock of LiNiCo, following which the holders of the Series A Preferred Stock shall participate in the distribution of any remaining assets with the holders of the junior stock on an as-converted basis. The Series A Preferred Stock is convertible into shares of LiNiCo common stock at the Company's&#160;option and is automatically converted into LiNiCo common stock upon the election of the holders of a majority of the LiNiCo Series A Preferred Stock or upon a qualifying IPO of LiNiCo common stock.&#160;The Series A Preferred Stockholders are also provided with preemptive rights allowing them the right to purchase their proportional share of certain future LiNiCo equity issuances.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;"&gt;The Series&#160;A Preferred Stock Purchase Agreement includes customary representations, warranties, and covenants by LiNiCo and the Company.&lt;/p&gt;

   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;"&gt;As LiNiCo&#x2019;s sale of the 375,000 of Aqua Shares resulted&#160;in net proceeds to LiNiCo that were less than $1,500,000, the Company&#160;was&#160;required to pay LiNiCo the difference of $232,000 in cash.&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;"&gt;In connection with the investment transactions, the Company&#160;also entered into an Investors Rights Agreement and a Voting Agreement, each dated &lt;em style="font: inherit;"&gt; February 15, 2021, &lt;/em&gt;pursuant to which LiNiCo granted the Company&#160;customary demand and piggyback registration rights, information rights and the right to nominate &lt;em style="font: inherit;"&gt;one&lt;/em&gt; person to the LiNiCo board of directors as long as the Company&#160;is&#160;the owner of at least &lt;em style="font: inherit;"&gt;10%&lt;/em&gt; of the LiNiCo&#160;common stock on a fully-diluted basis.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;

   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"&gt;On &lt;em style="font: inherit;"&gt; May 7, 2020, &lt;/em&gt;the Company received loan proceeds in the amount of approximately $332,000 under the Paycheck Protection Program (&#x201c;PPP&#x201d;). The PPP, established as part of the Coronavirus Aid, Relief and Economic Security Act (&#x201c;CARES Act&#x201d;), provides for loans to qualifying businesses. The loans and accrued interest are forgivable if the borrower uses the loan proceeds for eligible purposes, including payroll, benefits, rent and utilities, and maintains its payroll levels. The amount of loan forgiveness will be reduced if the borrower terminates employees or reduces salaries during a&#160;prescribed&#160;period.&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;"&gt;The unforgiven portion of the PPP loans are now payable over &lt;em style="font: inherit;"&gt;five&lt;/em&gt; years at an interest rate of &lt;em style="font: inherit;"&gt;1%,&lt;/em&gt; with a deferral of payments until &lt;em style="font: inherit;"&gt; September&#160;&lt;/em&gt;of &lt;em style="font: inherit;"&gt;2021.&lt;/em&gt; The Company believes&#160;it has used the loan proceeds for purposes consistent with the PPP requirements and has applied&#160;for loan forgiveness. During the&#160;&lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; March 31, 2021&lt;/em&gt;, &lt;em style="font: inherit;"&gt;one&lt;/em&gt; of the Company's &lt;em style="font: inherit;"&gt;two&lt;/em&gt; PPP loans for $131,000&#160;was forgiven. The Company believes the remaining PPP loan also qualifies for forgiveness. However, there is &lt;em style="font: inherit;"&gt;no&lt;/em&gt; assurance that the Company will be eligible for forgiveness of the remaining outstanding&#160;loan, in whole or in part.&lt;/p&gt;

   <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&#160;</p>
   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">Aqua Metals, Inc. (the &#8220;Company&#8221;) 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:c72479676">two</span> wholly-owned subsidiaries, Aqua Metals Reno, Inc. (&#8220;AMR&#8221;) and Aqua Metals Operations, Inc. (collectively, the &#8220;Subsidiaries&#8221;), 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">&#8482;</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: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">&#160;</p>
   <p style="font-family: &quot;Times New Roman&quot;, 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&#8217;s Tahoe Reno Industrial Center (&#8220;TRIC&#8221;) in McCarran, Nevada and intended to pursue the development of additional lead acid battery recycling facilities based on the Company&#8217;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: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">&#160;</p>
   <p style="font-family: &quot;Times New Roman&quot;, 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&#8217;s business plans. The Company believes this path 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>

Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, the valuation of conversion features of convertible debt, valuation allowances for deferred tax assets, the determination of fair value of estimated asset retirement obligations, the determination of stock option expense and the determination of the fair value of stock warrants issued.

For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following shares underlying outstanding convertible notes, stock options, RSUs and warrants to purchase common stock were antidilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive securities computation for the&#160;<em style="font: inherit;">three</em> months ended <em style="font: inherit;"> March 31</em>, as indicated below.</p> <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;">&#160;</p>

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>all revenue was derived from the sale of lead compounds and plastics.

   <p style="font-family: 'Times New Roman', Times, serif; font-size: 10pt; margin: 0pt; text-align: left">&#160;</p>
   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 8pt;">On <em style="font: inherit;"> February 15, 2021, </em>the Company&#160;entered into a Series&#160;A Preferred Stock Purchase Agreement with LINICO&#160;Corporation, a Nevada Corporation, or LiNiCo, that provided&#160;for the Company's&#160;issuance of 375,000 shares (&#8220;Aqua Shares&#8221;) of the Company's&#160;common stock in consideration of LiNiCo&#8217;s issuance of 1,500 shares of its Series A Preferred Stock, at a stated aggregate value of $1,500,000, along with a <span style="-sec-ix-hidden:c72479776">three</span>-year warrant (&#8220;Series A Warrant&#8221;) to purchase an additional 500 shares of LiNiCo Series A Preferred Stock at an exercise price of $1,000 per share. The <em style="font: inherit;">1,500</em> shares of the Series A Preferred Stock represents approximately 9% of LiNiCo common stock on a fully diluted basis, before giving effect to the Company's&#160;exercise of the Series A Warrant or any other outstanding warrants of LiNiCo.&#160;</p>
   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 8pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;">The Company accounted for the LiNiCo investment under ASC <em style="font: inherit;">321,</em> Investments-Equity Securities, using the measurement alternative of recording at cost as the investment in LiNiCo doesn&#8217;t have a readily determinable fair value.</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;">The LiNiCo Series A Preferred Stock is senior to all other capital stock of LiNiCo with regard to dividends and distributions upon liquidation, dissolution and sale of the company. Each share of LiNiCo Series A Preferred Stock is entitled to <em style="font: inherit;">one</em> vote per share and votes with the common stock on all matters, subject to certain protective provisions that require the approval of the holders of the Series A Preferred Stock voting as a class. The Series A Preferred Stock accrues a cumulative dividend of 8% per annum on the original stated value of $1,000 per share, and all accrued and unpaid dividends on the Series A Preferred Stock must be paid in full prior to the payment of any dividends on any other shares of LiNiCo capital stock. In the event of any liquidation or dissolution of LiNiCo, which would include a sale of LiNiCo, the holders of the Series A Preferred Stock shall receive the return of their stated value of <em style="font: inherit;">$1,000</em> per share plus all accrued and unpaid dividends prior to any distribution to the holders of any other capital stock of LiNiCo, following which the holders of the Series A Preferred Stock shall participate in the distribution of any remaining assets with the holders of the junior stock on an as-converted basis. The Series A Preferred Stock is convertible into shares of LiNiCo common stock at the Company's&#160;option and is automatically converted into LiNiCo common stock upon the election of the holders of a majority of the LiNiCo Series A Preferred Stock or upon a qualifying IPO of LiNiCo common stock.&#160;The Series A Preferred Stockholders are also provided with preemptive rights allowing them the right to purchase their proportional share of certain future LiNiCo equity issuances.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;">The Series&#160;A Preferred Stock Purchase Agreement includes customary representations, warranties, and covenants by LiNiCo and the Company.</p>

   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;">As LiNiCo&#8217;s sale of the 375,000 of Aqua Shares resulted&#160;in net proceeds to LiNiCo that were less than $1,500,000, the Company&#160;was&#160;required to pay LiNiCo the difference of $232,000 in cash.&#160;</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;">In connection with the investment transactions, the Company&#160;also entered into an Investors Rights Agreement and a Voting Agreement, each dated <em style="font: inherit;"> February 15, 2021, </em>pursuant to which LiNiCo granted the Company&#160;customary demand and piggyback registration rights, information rights and the right to nominate <em style="font: inherit;">one</em> person to the LiNiCo board of directors as long as the Company&#160;is&#160;the owner of at least <em style="font: inherit;">10%</em> of the LiNiCo&#160;common stock on a fully-diluted basis.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;margin:0pt 0pt 0pt 8pt;">Comstock Mining Inc., a Nevada corporation (NYSE-MKT: LODE), is the beneficial owner of approximately 50% of the common shares of LiNiCo. The Company's&#160;Chief Financial Officer, Judd Merrill, is a member of the board of directors of Comstock Mining.</p>

   <p style="font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt; margin: 0pt 0pt 0pt 27pt; text-align: justify;">On <em style="font: inherit;"> May 7, 2020, </em>the Company received loan proceeds in the amount of approximately $332,000 under the Paycheck Protection Program (&#8220;PPP&#8221;). The PPP, established as part of the Coronavirus Aid, Relief and Economic Security Act (&#8220;CARES Act&#8221;), provides for loans to qualifying businesses. The loans and accrued interest are forgivable if the borrower uses the loan proceeds for eligible purposes, including payroll, benefits, rent and utilities, and maintains its payroll levels. The amount of loan forgiveness will be reduced if the borrower terminates employees or reduces salaries during a&#160;prescribed&#160;period.</p>
