ITEM 1. BUSINESS
Item 1.
Business
Background
We were formed as a Delaware corporation on June 20, 2014 for the purpose of engaging in the business of recycling lead through a novel, proprietary and patent-pending process that we developed and named “AquaRefining”. Since our formation, we have focused our efforts on the development and testing of our AquaRefining process, the development of our business plan, the raise of our present working capital and the development of our initial lead acid battery, or LAB, recycling facility in the Tahoe Reno Industrial Center, McCarran, Nevada (“TRIC”).
We completed the development of our first LAB recycling facility at Nevada’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 twenty-four hours a day and seven days a week for sustained periods of time. The AquaRefining Aqualyzer 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.
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 due 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 sixteen 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.
As of the date of the fire, we had in place $50 million dollars in combined property, equipment and business interruption insurance. As of the date of this report, we have received approximately $23.5 million of insurance proceeds from our insurance carriers, of which $7.9 million was used to retire in full a credit facility encumbered by the land, facility and equipment at TRIC. As of the date of this report, we believe that the replacement value of the equipment and plant lost or damaged in the fire will likely be higher. We have also submitted a significant claim on our business interruption policy. 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. Assets on our balance sheet as of December 31, 2020 that were not affected by the fire total approximately $24.9 million 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.
Following the November 2019 fire, 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. We believe our capital light business strategy will require less space and less equipment and focus on the needs of our future licensees. As of the date of this report, 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 in that it could be far less capital intensive than a plant rebuild and could be funded solely or primarily from a combination of cash on hand, insurance proceeds and asset dispositions.
During the first half of 2020, we successfully performed test runs on the first and second iterations of our 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. In December 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 V1.25L program concluded with a multi-day endurance run for twenty-four hours and seven days a week that ended on December 24, 2020. The V1.25L doubled the throughput compared to the V1.0 Aqualyzer, resulting in a 50% reduction in the number of Aqualyzers needed for equivalent lead production. The 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 AquaRefining equipment installations. In addition, Aqualyzer operating expenses have been reduced by greater than 60% compared to the V1.0 Aqualyzer. We believe that the V1.25L Aqualyzer is commercially ready for licensing and sale, and we hope to conclude our initial AquaRefining licensing transaction in the second quarter of 2021, of which there can be no assurance.

Overview
Aqua Metals is seeking to reinvent lead recycling with its patented and patent pending AquaRefining™ technology. Unlike smelting, AquaRefining is a room temperature, water-based process. Lead is a globally traded commodity with a worldwide market value in excess of $20 billion. Lead acid batteries (LABs) are the primary consumer use of all lead produced in the world. Because the chemical and metallurgical properties of lead allow it to be recycled and reused indefinitely, LABs are also the dominant feed source for lead production across the world. As such, LABs are almost 100% recycled for purposes of capturing the lead contained therein for re-use. We believe that our proprietary and patented AquaRefining process will provide for the existing LAB recycling facility to leverage our capabilities for expanded production of a much higher purity lead with fewer environmental and regulatory issues than is possible with the current conventional methods of lead production.
In recent years, recycled lead has become increasingly important to LAB production. Recycled lead surpassed mined lead in the 1990s and now represents more than 65% of the lead content in new LABs. Whether it is produced from lead ore or recycled LABs, lead has historically been produced by smelting. Smelting is a high-temperature, metallurgical/chemical reduction, energy intensive and often a highly polluting process. As a consequence of the environmental and health issues, lead smelting has become increasingly regulated in many countries. In the U.S., regulatory non-compliance has forced the closure of large lead smelters in Vernon, California, Frisco, Texas and Herculaneum, Missouri over the last several years. In response to increasing environmental regulation over the past three decades, there has been an expansion of LAB smelting capacity in Mexico and other less regulated countries. The resulting transportation of used LABs from where they originate in the U.S. to smelters in Mexico, South Korea, the Philippines and elsewhere is an increasingly significant logistical and global environmental cost.
AquaRefining uses a bio-degradable aqueous solvent and a novel ambient temperature electro-chemical process to produce lead suitable for use in LAB production. Our AquaRefining process produces lead with a purity of 99.996+%, making it the purest lead ever made from a recycling technique that is in fact more pure than lead made from mining processes. We believe that AquaRefining can provide a more efficient production process as compared with alternative methods of producing equivalent grades of lead. For example, licensing the technology to facilities closest to the source of used LABs is more efficient due to minimization of transportation costs and supply chain bottlenecks. On this basis, we believe that AquaRefining reduces environmental plant emissions, health concerns and permitting needs compared with lead smelting. We believe that the combined advantages offered by AquaRefining represent a potential step change in lead recycling technology that includes improved product quality, advantages in footprint and logistics as well as reduced environmental impact.
The modular nature of AquaRefining makes it possible both to start LAB recycling at a smaller scale than is possible with a typical smelter setup and to add AquaRefining to existing battery recycling operations to expand production capacity or to reduce smelting processes. Our plan is to pursue the licensing of our AquaRefining technology. This strategy is designed to supply AquaRefining and supporting equipment to battery recyclers to improve emissions, throughput and product quality from their battery recycling operations.
Our Markets
The Lead Market
Lead is a globally traded metal commodity and is the essential component of over 80% of the world’s rechargeable batteries. Lead is globally traded primarily on the London Metals Exchange (LME), although the smaller Shanghai Metals Exchange (SHME) in China also trades the element. Conventionally in the industry, there are two separate groupings of lead: i) primary lead which refers to lead produced at primary smelters that use mined lead concentrates (generally lead sulfide) as their major feedstock, and ii) secondary lead which refers to lead smelters utilizing LABs as their main feed source.
Originally, the majority of the lead used in batteries was sourced from primary smelters but in recent decades, secondary lead has grown to become the dominate product used. Industry data shows that six million metric tons of lead was produced in 1995, of which approximately 45% was from primary and 55% was from secondary sources. Twenty years later, by 2015, global lead production had increased to approximately 11 million metric tons, of which more than 65% was secondary. Importantly, primary lead production had increased only marginally during this period. This marginal increase is partially due to lead-zinc mine deposits being depleted across the globe in existing mines. As such, an increasing quantity of primary lead is now the predominate byproduct of zinc mining.
In 2005, secondary lead traded on the LME in a range of $1,000 to $1,200 per metric ton. During 2020, secondary lead traded in a range of approximately $1,600 to $2,000 per metric ton.
As noted above, although lead is traded as a commodity on the LME/SHME, the major sales are directly between producers/traders and users (whom are typically battery manufacturers). The LME daily price is used as the benchmark in forming the basis of physical trades, forward contracts and hedge strategies for both primary and secondary lead. Based on market and product knowledge with buyers of lead in the U.S. and Global lead markets, different grades (termed alloys) of lead are traded at a premium to the base LME price. Lead alloys, which are generally specifically designed for the customer, are also sold at a premium above the base LME, whereas byproducts (generally lead compounds or scrap) are traded at a discount to the LME as they are based on the lead content and its form.
Lead Smelting
Currently, smelters produce virtually all the world’s mined and recycled lead. Smelting is an energy-intensive and, in some poorly managed plants, a highly polluting process. At its core, smelting is a relatively high temperature (excess of 900°C) metallurgical reduction process in which lead compounds are heated and reacted with various reducing agents to remove the oxygen, sulfur, and other impurities. The process leaves behind bullion lead and waste slag. In smelting, depending upon the operation, 0.5% to 5% of the lead can be lost to the “slag”, with the resultant lead bullion containing both wanted and unwanted impurities.
In developed countries, there is both increased environmental regulation and enforcement of such, including monitoring of permissible blood lead levels in employees and local populations. These regulations and the increasing enforcement have made it more expensive to operate smelters. According to a report titled “Hazardous Trade?” produced by the Secretariat of the Commission for Environmental Cooperation in 2013, this has led to a decline of lead smelters in the U.S., an expansion of smelting operations in Mexico and a resultant increase in the export of used LABs from the U.S. followed by the re-import of recycled lead. This trade is believed to be largely driven by the lower costs related to the less stringent environmental standards and enforcement in Mexico. For the foregoing reasons, we believe that lead smelting facilities are increasingly located in less regulated areas remote from both the source of used LABs and the demand for lead. We believe that the remote location of smelting increases the transport costs to the production of recycled lead.
Lead Acid Batteries
Although the LAB is one of the earliest battery technologies, in terms of energy capacity deployed and installed manufacturing capacity, it still dominates the battery industry today. Historically, the largest market for LABs has been as starter batteries for vehicles. However, with the increasing electrical load on modern vehicles and the adoption of “Stop-Start” conventional 12V “starter batteries”, LABs are evolving into more capable and higher value products. At the same time, large new markets such as Cell Tower, Data Center and Industrial back-up are adding to demand. Consequently, existing LAB production facilities are being expanded and new facilities are being built.
According to Grand View Research, annual lead acid battery sales are expected to nearly double to $84 billion by 2025, driving demand for lead. Similar prospects for healthy growth in the lead industry continue to be published and support continued growth in demand for lead for at least the next 20 years. We believe that grid storage and other energy storage applications linked to renewable energy (solar and wind) will also generate increased demand for LABs, where low cost, safety and reliability will make them attractive options.
The increase in LAB manufacturing in general and particularly in China, India and Southeast Asia, has increased demand for lead, putting pressure on global recycling networks to meet this demand. At present, we believe that much of the LAB recycling performed outside of the U.S., Canada, the EU, Japan, and Australia is carried out in outdated facilities with poor environmental standards and insufficient enforcement. China, India, Pakistan and South America appear to be moving toward tougher regulation and enforcement. We believe that this will drive a demand in foreign markets for more less polluting LAB recycling processes.
AquaRefining Process
We developed AquaRefining to be a cleaner and modular alternative to smelting. Our process has two key elements, both of which are integral to our issued patents and pending-patent applications. The first is our use of a proprietary, non-toxic solvent that dissolves lead compounds. The second is a proprietary electro-chemical process and Aqualyzer that converts the dissolved lead compounds into high purity lead suitable for use in LAB production.
Similar to conventional LAB smelter recycling, our AquaRefining process begins with the crushing of used LABs and the separation of the metallic lead, active material (lead compounds), sulfuric acid and plastic for recycling. The active material (lead compounds) are first processed to remove sulfur and then dissolved in our solvent. Lead is then plated from the solvent using our patented and patent-pending process allowing the solvent to be reused.
Our AquaRefining process can generate the following outputs:
•
Lead and lead-based products, including high purity lead, lead alloys and lead compounds which are primarily intended for the LAB industry. We are also exploring higher value lead-based products which may offer performance and life-cycle benefits to the LAB industry; and
•
Recovered plastic chips, intended for re-use in the manufacture of battery casings and other recycled plastic products.
A significant benefit of our AquaRefining process is that it is capable of producing higher purity product than that derived from primary smelters with product from secondary sources. As indicated above, primary grade lead is generally sold directly to battery companies.
Another significant benefit of our process is that we designed our AquaRefining equipment to be manufactured on a purpose-built production line in standard sized Aqualyzers. This is not possible with the smelting process, as smelters need to be constructed on site. This gives us the ability to provide AquaRefining systems with capacities ranging from eight metric tons per day to more than 800 metric tons per day all based on our recently enhanced standard Aqualyzer. We have also developed an integrated software and portal that keeps track of lead production and key operating metrics.
Lead recycling is subject to a variety of domestic and international regulations related to hazardous materials, emissions, employee safety and other matters. While our operations will be subject to these regulations, we believe that one of our potential advantages will be our ability to conduct lead recycling operations with less regulatory cost and burden than smelting operators due to the nature of our process. One of our key objectives will be to educate regulators and the public as to the environmental benefits of AquaRefining. We believe that we have the potential to develop a business model that offers the opportunity to conduct, in an environmentally friendly manner, an important recycling activity that historically has been conducted in an often highly polluting manner.
Our Business Model
Overall, our objective is to progress the lead recycling industry from one which is based solely on smelting to one which is based on AquaRefining supplemented by smelting. The business model that we are currently most focused on is the supply of AquaRefining and supporting equipment and services to third parties to use in their recycling operations on a licensing model with running royalties to Aqua Metals for lead produced. We are currently focused on exploring this business stream through our relationship with Clarios and other existing smelters.
The market for lead is global in scale but local in nature and execution, with large differences in local regulation, custom and practice, and access to transportation and electricity costs. In some regions, it is highly regulated, and in others it is not. Consequently, we are evolving our business model to commercialize our technology optimally across multiple locations.
In the U.S. and similarly regulated countries, our plan is to supply AquaRefining technology to LAB recycling facilities, both directly and in association with third parties through joint ventures, licensing and direct sales. We intend to work with all potential parties that would be interested in our AquaRefining technology. As an example, on February 7, 2017, we entered into a series of agreements with Clarios (formerly Johnson Controls, Inc), pursuant to which, among other things, we agreed to work with Clarios on the development of a program for upgrades of Clarios and certain strategic partners of Clarios' existing lead smelters throughout North and South America, China and Europe to a lead recycling process utilizing our proprietary and patented AquaRefining technology and equipment, know-how and services. In June 2019, we signed an agreement with Clarios setting parameters for finalizing a definitive development program. Those performance conditions, however, were based on the operation of up to 16 AquaRefining modules at TRIC, and our ability to meet these performance conditions is unlikely if the Company pursues a technology licensing business plan without rebuilding TRIC to its pre-fire status as discussed in the “Background” section above. We have initiated discussions with Clarios to revise the performance conditions, however as of the date of this report we have been unable to reach an agreement with Clarios on revised performance standards. 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’s earlier termination. However, there can be no assurance that we will be able to conclude a definitive development agreement with Clarios on terms that benefit us, if at all. See "Risk Factors - Risks Related to Our Business."
Competition
At the present time, our primary competition in the production of lead comes from operators of existing smelters and other parties heavily invested in the existing supply chain for smelting. Our approach to this competition is to make AquaRefining available for the conversion of existing smelter-based facilities. However, it is prudent to assume that outside of our strategic relationships, a conversion to AquaRefining may be resisted by some of the incumbent lead producers. Competition in the supply of lead from such incumbents may come in the form of price competition for lead produced. However, to the extent we are successful with partners in being a producer of high-quality lead without the regulatory costs or burden associated with smelting, we believe that we may be able to compete effectively with smelting as the preferred method of recycling lead, at least in the more regulated jurisdictions.
Secondary competition comes from other alternatives to lead smelting that are electrochemical based. There are a few groups that have run lab scale and bench tests but to date, no alternate technology has been commercialized to produce large quantities of consistent quality lead whereas Aqua Metals has already done so.
Licensing of our Technology
Our recycling facility located at TRIC was used in the previous years to prove out our AquaRefining process. During this time we began continuous production of AquaRefined lead and sold it at a premium to the London Metals Exchange ("LME"). We also received approved lead supplier status from Clarios and we shipped approximately 35,000 ingots directly to their battery manufacturing facility. We have invested over $200 million towards commercialization, filing 62 patent applications and having 51 patents issued or allowed in the U.S. and internationally for lead and other metals.
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. 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.
Revenues related to the licensing of our technology may include engineering services, equipment supply and recurring running royalties on lead production.
Clarios Agreements
Equipment Supply Agreement. We entered into an equipment supply agreement dated February 7, 2017 with Clarios, formerly Johnson Controls Inc., pursuant to which we agreed to collaborate on the development of a program for the installation of new greenfield builds and conversion of existing Clarios and certain strategic partners of Clarios existing lead smelters to a lead recycling process utilizing our proprietary and patent-pending AquaRefining technology and equipment, know-how and services. We have agreed with Clarios to develop an appropriate program blueprint, and enter into a definitive development program agreement reflecting that blueprint, pursuant to which we will provide to Clarios and certain strategic partners of Clarios, by way of licensing or sale, the following products and services in the regions of North and South America, Europe and China:
•
AquaRefining technology and the related equipment, engineering and systems integration support sufficient to convert or retrofit existing smelter-based operations and/or the construction of new Clarios and Clarios’ strategic partners’ battery recycling facilities based on our AquaRefining technology;
•
Training, evaluation and certification of Clarios’ operations personnel sufficient for such personnel to competently operate our AquaRefining technology and equipment; and
•
Ongoing technical support, maintenance services and warranties.
We plan to provide the above services and equipment to Clarios on a serviced license basis, including Clarios’ ongoing licensing fees payable to us based on the operational capacity of the AquaRefining equipment supplied by us. 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 a definitive development program agreement reflecting the above blueprint, including 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 up to 16 AquaRefining modules at TRIC, which now seems unlikely. If we are unable to agree with Clarios on revised performance standards, we will 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’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.
The equipment supply agreement allows each party the right to seek early termination based on a material breach by the other party that goes uncorrected for 30 days following notice of breach. The equipment supply agreement contains representations, warranties and indemnities that are customary to commercial agreements of this nature.
Tolling/Lead Purchase Agreement. We entered into a tolling/lead purchase agreement dated February 7, 2017 with Clarios pursuant to which we have agreed to sell to Clarios, and Clarios has agreed to purchase from us, recycled lead on both a tolling (fee to convert used LABs to recycled materials) and merchanting (sale of recycled materials) basis.
Pursuant to the agreement, Clarios has agreed to purchase from us, and we have agreed to sell to Clarios, up to 100% of the recycled lead we produce for automotive applications, other than by way of tolling arrangements, on a monthly basis, unless we receive notice from Clarios six months advance of its intention to purchase less than 100% of our output in any given month. Our agreement with Clarios excludes, and we are free to manufacture and sell to third parties, recycled lead for non-automotive uses, such as stationery batteries for back-up power systems for Internet/Cloud applications or grid scale storage applications. During fiscal year 2020 and 2019, approximately 16% and 69% of our revenues, respectively, were derived from sales to Clarios.
Veolia Agreement
In February 2019, we entered into an Operations, Management and Maintenance Agreement with Veolia North America Regeneration Services, LLC, or Veolia. Pursuant to the Agreement, Veolia agreed to provide development of operations programs, start-up of new equipment and operations, maintenance and management services at our AquaRefining facility at TRIC. As a result of the November 2019 fire at TRIC, we have suspended all operations at TRIC pending our clean-up of the fire damage and development of our plan for resuming operations. In January 2020, we declared a force majeure under the Veolia Operations, Management and Maintenance Agreement and suspended payments to Veolia thereunder. The Veolia Operations, Management and Maintenance Agreement included an initial term expiring March 6, 2021 and an automatic renewal provision unless either party elects not to renew. We have elected not to renew the Veolia Operations, Management and Maintenance Agreement and it is presently scheduled to terminate on March 6, 2021. See "Risk Factors - Risks Related to Our Business."
Intellectual Property Rights
We regard the protection of our technologies and intellectual property rights as an important element of our business operations and crucial to our success. We endeavor to generate and protect our intellectual property assets through a series of patents, trademarks, internal and external policy and procedures and contractual provisions.
Patent Portfolio
Currently, we have secured six US patents, 40 international patents, and five allowances (all international). In addition to the US patents, we have international patents/allowances in the African Regional Intellectual Property Organization, European Union, the Eurasian Patent Organization, Honduras, India, Indonesia, South Korea, Japan, China, Australia, Canada, African Intellectual Property Organization, Mexico, South Africa, Vietnam, and the Ukraine. We also have 62 US and foreign patent applications pending with patent applications pending in 20 additional non-US jurisdictions across seven distinct patent applications relating to certain elements of the technology underlying our AquaRefining process and related apparatus and chemical formulations. The claims of the granted patents substantially address the same subject matter and are drawn to various aspects of processing lead materials using an aqua refining process. Differences in the claim number and scope are due to local rules and practice.
We intend to continue to prepare and file domestic and foreign patent applications covering expanding aspects and applications of our technology, as circumstances warrant.
There can be no assurance that any patents will issue from any of our current or any future applications. Also, any patents that may issue may not survive a legal challenge to their scope, validity or enforceability, or provide significant protection for us. Competitors may work around our patents so they are not infringing. Our patent portfolio and our existing policy and procedures safeguarding our trade secrets nonetheless may face challenges so that our competitors can copy our AquaRefining process.
Trademark Portfolio
We have filed for trademark registration in the US and foreign countries for the following trademarks:
•
AQUA METALS (US and 15 foreign countries)
•
AQUAREFINING (US and 11 foreign countries)
•
AQUAREFINE (US only)
•
AQMS (US only)
•
AQUAFIT (US only)
Trade Secrets and Contract Protection
We have developed our internal policy and procedures in safeguarding our trade secrets and proprietary information. Our procedures generally require our employees, consultants and advisors to enter into confidentiality agreements. These agreements provide that all confidential information developed or made known to the individual during the course of the individual’s relationship with us is to be kept confidential and not disclosed to third parties except under specific circumstances. In the case of our employees, the agreements provide that all of the technology that is conceived by the individual during the course of employment is our exclusive property. The development of our technology and many of our processes are dependent upon the knowledge, experience and skills of key scientific and technical personnel.
Government Regulation
Our operations and the operations of our licensees in the United States will be subject to the federal, state and local environmental, health and safety laws applicable to the reclamation of LABs. While the lead reclamation process itself is generally not subject to federal permitting requirements, depending on how any particular operation is structured, our facilities and the facilities our licensees may have to obtain environmental permits or approvals from federal, state or local regulators to operate, including permits or regulatory approvals related to air emissions, water discharges, waste management, and the storage of LABs on-site should that become necessary. We may face opposition from local residents or public interest groups to the installation and operation of our or our licensee's facilities. Failure to secure (or significant delays in securing) the necessary approvals could prevent us from pursuing some of our planned operations and adversely affect our business, financial results and growth prospects.
In addition to permitting requirements, our operations and the operations of our licensees are subject to environmental health, safety and transportation laws and regulations that govern the management of and exposure to hazardous materials such as the lead and acids involved in LAB reclamation. These include hazard communication and other occupational safety requirements for employees, which may mandate industrial hygiene monitoring of employees for potential exposure to lead. Failure to comply with these requirements could subject our business to significant penalties (civil or criminal) and other sanctions that could adversely affect our business. Changes to these regulatory requirements in the future could also increase our costs, require changes in or cessation of certain activities, and adversely affect the business.
The nature of our operations and the operations of our licensees involves risks, including the potential for exposure to hazardous materials such as lead, that could result in personal injury and property damage claims from third parties, including employees and neighbors, which claims could result in significant costs or other environmental liability. Our operations and the operations of our licensees also pose a risk of releases of hazardous substances, such as lead or acids, into the environment, which can result in liabilities for the removal or remediation of such hazardous substances from the properties at which they have been released, liabilities which can be imposed regardless of fault, and our business could be held liable for the entire cost of cleanup even if we were only partially responsible. Like any manufacturer, we and our licensees are also subject to the possibility that we may receive notices of potential liability in connection with materials that were sent to third-party recycling, treatment, and/or disposal facilities under the Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (“CERCLA”), and comparable state statutes, which impose liability for investigation and remediation of contamination without regard to fault or the legality of the conduct that contributed to the contamination, and for damages to natural resources. Liability under CERCLA is retroactive, and, under certain circumstances, liability for the entire cost of a cleanup can be imposed on any responsible party.
As our business expands outside of the United States, our licensed operations will be subject to the environmental, health and safety laws of the countries where we do business, including permitting and compliance requirements that address the similar risks as do the laws in the United States, as well as international legal requirements such as those applicable to the transportation of hazardous materials. Depending on the country or region, these laws could be as stringent as those in the US, or they could be less stringent or not as strictly enforced. In some countries in which we are interested in expanding our business, such as Mexico and China, the relevant environmental regulatory and enforcement frameworks are in flux and subject to change. Therefore, while compliance with these requirements will cause our business to incur costs, and failure to comply with these requirements could adversely affect our business, it is difficult to evaluate such potential costs or adverse impacts until such time as we decide to initiate operations in particular countries outside the United States.

ITEM 1A. RISK FACTORS
Item 1A.
Risk Factors
Investing in our common stock involves a high degree of risk. Before purchasing our common stock, you should read and consider carefully the following risk factors as well as all other information contained in this report, including our consolidated financial statements and the related notes. Each of these risk factors, either alone or taken together, could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock. There may be additional risks that we do not presently know of or that we currently believe are immaterial, which could also impair our business and financial position. If any of the events described below were to occur, our financial condition, our ability to access capital resources, our results of operations and/or our future growth prospects could be materially and adversely affected and the market price of our common stock could decline. As a result, you could lose some or all of any investment you may make in our common stock.
Risks Relating to Our Business
We have experienced a fire at our TRIC facility which has caused significant damage and, as a result of the fire, we revised our plans for the commercialization of our AquaRefining technologies. However, there can be no assurance that such plans will be successful. On the evening of November 29, 2019, a fire occurred at our LAB recycling facility at TRIC. The cause of ignition is likely related to on-site contractor work that was being performed on the day of the fire. The fire was substantially contained to the AquaRefining area of the plant, however the fire destroyed or impaired beyond recovery substantially all of the AquaRefining equipment, including all 16 AquaRefining modules, control wiring and other supporting infrastructure.
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.
Our business strategy includes licensing arrangements and entering into joint ventures and strategic alliances, however as of the date of this report we have no such agreements in place and there can be no assurance we will be able to do so. Failure to successfully integrate such licensing arrangements, joint ventures, or strategic alliances into our operations could adversely affect our business. We propose to commercially exploit our AquaRefining process primarily by licensing our technology to third parties and entering into joint ventures and strategic relationships with parties involved in the manufacture and recycling of LABs, including Clarios, among others. Although we are currently seeking to negotiate such an agreement with Clarios as further discussed herein, as of the date of this report, we have not entered into any such licensing, joint venture or strategic alliance agreements, apart from our equipment supply agreement with Clarios, and there can be no assurance that we will be able to do so on terms that benefit us, if at all. Our ability to enter into licensing, joint ventures and strategic relationships with third parties will depend on our ability to demonstrate the technological and commercial advantages of our AquaRefining process, of which there can be no assurance. Also, even if we are able to enter into licensing, joint venture or strategic alliance agreements, there can be no assurance that we will be able to obtain the expected benefits of any such arrangements. In addition, licensing programs, joint ventures and strategic alliances may involve significant other risks and uncertainties, insufficient revenue generation to offset liabilities assumed and expenses associated with the transaction, potential additional challenges in protecting our intellectual property, and unidentified issues not discovered in our due diligence process, such as product quality, technology issues and legal contingencies. In addition, we may be unable to effectively integrate any such programs and ventures into our operations. Our operating results could be adversely affected by any problems arising during or from any licenses, joint ventures or strategic alliances.
Since we have a limited operating history and have only recently commenced revenue producing operations, it is difficult for potential investors to evaluate our business. We formed our corporation in June 2014 and only commenced revenue producing operations in the first quarter of 2017. From inception through December 31, 2020, we generated a total of $11.5 million 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. As of the date of this report, we are unable to estimate when we expect to commence 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:
•
the timing and success of our plan of commercialization and the fact that we have suspended operations at TRIC;
•
our ability to demonstrate that our AquaRefining technology can be operated on a commercial scale;
•
our ability to license our AquaRefining process and sell our AquaRefining equipment to recyclers of LABs; and
•
our ability to realize the expected benefits of our strategic partnerships with Clarios and BASF.
Investors should evaluate an investment in us in light of the uncertainties encountered by developing companies in a competitive environment. There can be no assurance that our efforts will be successful or that we will ultimately be able to attain profitability.
Our business is dependent upon our successful implementation of novel technologies and processes and there can be no assurance that we will be able to implement such technologies and processes in a manner that supports the successful commercial roll-out of our business model. While much of the technology and processes involved in lead recycling operations are widely used and proven, our AquaRefining process is largely novel and, to date, has been demonstrated on a modest scale of operations. While we have shown that our proprietary technology can produce AquaRefined lead on a small scale, we had just begun to demonstrate that we can produce AquaRefined lead on a commercial scale prior to the November 2019 fire at TRIC. Further, as we endeavored to complete our AquaRefining production line, we continuously encountered unforeseen complications that delayed the ramping up of our AquaRefining modules and the integration of our AquaRefining process with the traditional lead recycling operations. There can be no assurance that we will not encounter similar unforeseen complications as we pursue our revised business model.
We may need additional financing to execute our business plan and fund operations, which additional financing may not be available on reasonable terms or at all. As of December 31, 2020, we had total cash of $6.5 million and working capital of $4.9 million. As of the date of this report, we believe that we may require additional capital in order to fund our current level of ongoing costs and our proposed business plan over the next 12 months as we move forward with our capital light licensing strategy. We intend to acquire the necessary capital though the recovery of insurance proceeds on our fire related claims and the possible sale of certain equipment and assets at TRIC. However, there can be no assurance that we will be able to collect insurance proceeds or acquire proceeds from the sale of TRIC in amounts sufficient to fund the capital requirements or, if we are successful, that we will not require additional capital. If needed, we may seek funding through the sale of equity or debt financing. Funding that includes the sale of our equity may be dilutive. If such funding is not available on satisfactory terms, we may be unable to further pursue our business plan and we may be unable to continue operations, in which case you may lose your entire investment.
Our business may be adversely affected by the recent coronavirus outbreak. In December 2019, a novel strain of coronavirus was reported to have surfaced in Wuhan, China. In January 2020, this coronavirus spread to other countries, including the United States, and efforts to contain the spread of this coronavirus intensified. At this time, we and most of our partners and suppliers are subject to travel restrictions, shelter in place requirements and limited, if any, operations. The outbreak and any preventative or protective actions that we or our partners and suppliers may take in respect of this coronavirus may result in a period of disruption to work in progress. Our partners’ and suppliers’ businesses could be disrupted, and our ongoing and future recovery from the TRIC fire, resumption of limited V1.25L operations and license negotiations could be negatively affected. Any resulting financial impact cannot be reasonably estimated at this time but may materially affect our business and financial condition. The extent to which the coronavirus impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others.
We have elected not to renew our current agreement with Veolia and it is unlikely that we will continue to partner with Veolia. In February 2019, we entered into an Operations, Management and Maintenance Agreement with Veolia North America Regeneration Services, LLC, or Veolia. Pursuant to the Agreement, Veolia agreed to provide development of operations programs, start-up of new equipment and operations, maintenance and management services at our AquaRefining facility at TRIC. As a result of the November 2019 fire at TRIC, we have suspended all operations at TRIC pending our clean-up of the fire damage and development of our plan for resuming operations. In January 2020, we declared a force majeure under the Veolia Operations, Management and Maintenance Agreement and suspended payments to Veolia thereunder. The Veolia Operations, Management and Maintenance Agreement included an initial term expiring March 6, 2021 and an automatic renewal provision unless either party elects not to renew. We have elected not to renew the Veolia Operations, Management and Maintenance Agreement and it is presently scheduled to terminate on March 6, 2021.
Our business model is new and has not been proven by us or anyone else. We are engaged in the business of producing recycled lead through a novel, and proven on a modest scale, technology. While the production of recycled lead is an established business, to date all recycled lead has been produced by way of traditional smelting processes. To our knowledge, no one has successfully produced recycled lead in commercial quantities other than by way of smelting. In addition, neither we nor anyone else has ever successfully built a production line that commercially recycles LABs without smelting. Further, there can be no assurance that either we or our licensees will be able to produce AquaRefined lead in commercial quantities at a cost of production that will provide us and our proposed licensees with an adequate profit margin. The uniqueness of our AquaRefining process presents potential risks associated with the development of a business model that is untried and unproven.
Even if our licensees are successful in recycling lead using our processes, there can be no assurance that the AquaRefined lead will meet the certification and purity requirements of our potential customers. A key component of our business plan is the production of recycled lead through our AquaRefining process of the highest purity (at least 99.99% pure lead), which we refer to as AquaRefined lead. We believe that our AquaRefined lead will provide our licensees with a revenue premium over the market price of lead on the London Metal Exchange, or LME, and, more importantly, the ability to produce AquaRefined lead will be vital to confirming the efficacy and relevancy of our proprietary technology. Our licensees and their customers will require that our AquaRefined lead meet certain minimum purity standards and, in all likelihood, require independent assays to confirm the lead’s purity. As of the date of this report, we have produced limited quantities of AquaRefined lead and in November 2018, Clarios confirmed its approval of the purity of our AquaRefined lead by providing to us official vendor approval to receive finished lead at its manufacturing facilities. However, we have not produced AquaRefined lead in significant commercial quantities and there can be no assurance that our licensees will be able to do so or, if our licensees are able to produce AquaRefined lead in significant commercial quantities, that such lead will continue to meet the required purity standards of their customers.
While we have been successful in producing AquaRefined lead in small volumes, there can be no assurance that either we or our licensees will be able to replicate the process, along with all of the expected economic advantages, on a large commercial scale either for us or our prospective licensees. Our commercial operations have primarily involved the production of lead compounds and plastics from recycled LABs, and more recently, the sale of lead bullion and AquaRefined lead. In April 2018, we commenced the limited production of cast lead bullion (mixture of lead purchased to prime the kettles and AquaRefined lead from our AquaRefining process), and in June 2018, we commenced the sale of pure AquaRefined lead in the form of two tonne blocks. While we believe that our development, testing and limited production to date has validated the concept of our AquaRefining process, the limited nature of our operations to date are not sufficient to confirm the economic returns on our production of recycled lead. There can be no assurance that our licensees will be able to produce AquaRefined lead in commercial quantities at a cost of production that will provide us and our proposed licensees with an adequate profit margin.
Our business may be negatively affected by labor issues and higher labor costs. Our ability to maintain our workforce depends on our ability to attract and retain new and existing employees. As of the date of this report, none of our employees are covered by collective bargaining agreements and we consider our labor relations to be acceptable. However, we could experience workforce dissatisfaction which could trigger bargaining issues, employment discrimination liability issues as well as wage and benefit consequences, especially during critical operation periods. We could also experience a work stoppage or other disputes which could disrupt our operations and could harm our operating results. In addition, legislation or changes in regulations could result in labor shortages and higher labor costs. There can be no assurance that we may not experience labor issues that negatively impact our operations or results of operations.
Our intellectual property rights may not be adequate to protect our business. As of the date of this report, we have secured granted/allowed patents in the following countries/regions: U.S. (9837689, 10665907, 10793957, 10689769, 10340561, 10316420), Canada (2930945), China (201480071929.1, 201680041675.8, 201680041600.X, 201680041571.7, 201580062811.7), Europe (3072180, 3294916, 3221918, and allowed 3483305), Eurasia (32371, 35532, and allowed 201791004), South Africa (2016/04083, 2017/08454, 2017/08455, 2017/04123, 2018/04384), South Korea (101739414, 101882932, 101926033, 102096976), Honduras (80-2019), India (318321), Indonesia (IDP000061176, IDP000066550), Japan (6173595, 6805240, 6775006, 6592088), Mexico (357027), OAPI (17808, 19078, 18736), Ukraine (118037, 119580), Vietnam (22588) Australia (2014353227, 2015350562, 2016260407, 2017213449, and allowed 2016260408, ARIPO (4995, and allowed AP/P/2017/009999), and Chile (allowed 2018-01459).
We also have further patent applications pending in the United States and numerous corresponding patent applications pending in 20 additional jurisdictions relating to certain elements of the technology underlying our AquaRefining process and related apparatus and chemical formulations. However, no assurances can be given that any patent issued, or any patents issued on our current and any future patent applications, will be sufficiently broad to adequately protect our technology. In addition, we cannot assure you that any patents issued now or in the future will not be challenged, invalidated, or circumvented.
Even patents issued to us may not stop a competitor from illegally using our patented processes and materials. In such event, we would incur substantial costs and expenses, including lost time of management in addressing and litigating, if necessary, such matters. Additionally, we rely upon a combination of trade secret laws and nondisclosure agreements with third parties and employees having access to confidential information or receiving unpatented proprietary know-how, trade secrets and technology to protect our proprietary rights and technology. These laws and agreements provide only limited protection. We can give no assurance that these measures will adequately protect us from misappropriation of proprietary information.
Our processes may infringe on the intellectual property rights of others, which could lead to costly disputes or disruptions. The applied science industry is characterized by frequent allegations of intellectual property infringement. Though we do not expect to be subject to any of these allegations, any allegation of infringement could be time consuming and expensive to defend or resolve, result in substantial diversion of management resources, cause suspension of operations or force us to enter into royalty, license, or other agreements rather than dispute the merits of such allegation. If patent holders or other holders of intellectual property initiate legal proceedings, we may be forced into protracted and costly litigation. 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.
There can be no assurance that we will be able to negotiate our key agreement with Clarios on commercially reasonable terms, or at all. 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’ 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’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.
There can be no assurance that Clarios will maintain the same level of interest in and commitment to the proposed joint development of our AquaRefining technologies. On May 1, 2019, Johnson Controls International plc announced that it had completed the sale of its battery group assets, formerly held by Johnson Controls Battery Group, Inc., to Brookfield Business Partners L.P. The acquired battery group assets now operates under the name Clarios. 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 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’ sale of its battery group assets to Brookfield Business Partners L.P. could possibly have a material adverse effect on the Aqua Metals Collaboration.
Global economic conditions could negatively affect our prospects for growth and operating results. Our prospects for growth and operating results will be directly affected by the general global economic conditions of the industries in which our suppliers, partners and customer groups operate. 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 per tonne on May 5, 2015 to a low of $1,554 per tonne on November 23, 2015 because of fluctuations in the market. Lead price per tonne was approximately $2,018 at the end of December 2020. 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.
We are subject to the risks of conducting business outside the United States. A part of our strategy involves our pursuit of growth opportunities in certain international market locations. We intend to pursue licensing or joint venture arrangements with local partners who will be primarily responsible for the day-to-day operations. Any expansion outside of the US will require significant management attention and financial resources to successfully develop and operate any such facilities, including the sales, supply and support channels, and we cannot assure you that we will be successful or that our expenditures in this effort will not exceed the amount of any resulting revenues. Our international operations expose us to risks and challenges that we would otherwise not face if we conducted our business only in the United States, such as:
•
increased cost of enforcing our intellectual property rights;
•
diminished ability to protect our intellectual property rights;
•
heightened price sensitivities from customers in emerging markets;
•
our ability to establish or contract for local manufacturing, support and service functions;
•
localization of our LABs and components, including translation into foreign languages and the associated expenses;
•
compliance with multiple, conflicting and changing governmental laws and regulations;
•
compliance with the Federal Corrupt Practices Act and other anti-corruption laws;
•
foreign currency fluctuations;
•
laws favoring local competitors;
•
weaker legal protections of contract terms, enforcement on collection of receivables and intellectual property rights and mechanisms for enforcing those rights;
•
market disruptions created by public health crises in regions outside the United States;
•
difficulties in staffing and managing foreign operations, including challenges presented by relationships with workers’ councils and labor unions;
•
issues related to differences in cultures and practices; and
•
changing regional economic, political and regulatory conditions.
U.S. government regulation and environmental, health and safety concerns may adversely affect our business. Our operations and the operations of our licensees in the United States will be subject to the federal, state and local environmental, health and safety laws applicable to the reclamation of lead acid batteries including the Occupational Safety and Health Act ("OSHA") of 1970 and comparable state statutes. Our facilities and the facilities of our licensees will have to obtain environmental permits or approvals to expand, including those associated with air emissions, water discharges, and waste management and storage. We and our licensees may face opposition from local residents or public interest groups to the installation and operation of our respective facilities. In addition to permitting requirements, our operations and the operations of our licensees are subject to environmental health, safety and transportation laws and regulations that govern the management of and exposure to hazardous materials such as the lead and acids involved in battery reclamation. These include hazard communication and other occupational safety requirements for employees, which may mandate industrial hygiene monitoring of employees for potential exposure to lead.
We and our licensees are also subject to inspection from time to time by various federal, state and local environmental, health and safety regulatory agencies and, as a result of these inspections, we and our licensees may be cited for certain items of non-compliance. For example, in August 2018, the Nevada Occupational Safety and Health Administration, or Nevada OSHA, delivered to us a citation and notification of penalty. The citation listed a number of items related to our compliance with Nevada OSHA’s Lead Standard. We reached a settlement agreement with Nevada OSHA on the amount of penalties associated with the citation. We also agreed to engage a lead compliance expert to audit our facility at TRIC for compliance with all provision of the Lead Standard and to generate a written report with findings of any noncompliance, recommended corrective actions, and a time frame to correct the findings of noncompliance. We agreed with Nevada OSHA to correct all findings of noncompliance within the time frame proposed by the lead compliance expert in their report. The lead compliance expert has been engaged, has visited the facility at TRIC and has completed the written report. We have corrected all findings of noncompliance in a timely manner.
Failure to comply with the requirements of federal, state and local environmental, health and safety laws could subject our business and the businesses of our licensees to significant penalties (civil or criminal) and other sanctions that could adversely affect our business. In addition, in the event we are unable to operate and expand our AquaRefining process and operations as safe and environmentally responsible, we and our licensees may face opposition from local governments, residents or public interest groups to the installation and operation of our facilities.
The development of new AquaRefining technology by us or our partners or licensees, and the dissemination of our AquaRefining process will depend on our ability to acquire necessary permits and approvals, of which there can be no assurance. As noted above, our AquaRefining processes will have to obtain environmental permits or approvals to operate, including those associated with air emissions, water discharges, and waste management and storage. In addition, we expect that any use of AquaRefining operations at our partner's facilities will require additional permitting and approvals. Failure to secure (or significant delays in securing) the necessary permits and approvals could prevent us and our partners and licensees from pursuing additional AquaRefining expansion, and otherwise adversely affect our business, financial results and growth prospects. Further, the loss of any necessary permit or approval could result in the closure of an AquaRefining facility and the loss of our investment associated with such facility.
Our business involves the handling of hazardous materials and we may become subject to significant fines and other liabilities in the event we mishandle those materials. The nature of our operations involves risks, including the potential for exposure to hazardous materials such as lead, that could result in personal injury and property damage claims from third parties, including employees and neighbors, which claims could result in significant costs or other environmental liability. Our operations also pose a risk of releases of hazardous substances, such as lead or acids, into the environment, which can result in liabilities for the removal or remediation of such hazardous substances from the properties at which they have been released, liabilities which can be imposed regardless of fault, and our business could be held liable for the entire cost of cleanup even if we were only partially responsible. We are also subject to the possibility that we may receive notices of potential liability in connection with materials that were sent to third-party recycling, treatment, and/or disposal facilities under the Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, or CERCLA, and comparable state statutes, which impose liability for investigation and remediation of contamination without regard to fault or the legality of the conduct that contributed to the contamination, and for damages to natural resources. Liability under CERCLA is retroactive, and, under certain circumstances, liability for the entire cost of a cleanup can be imposed on any responsible party. Any such liability could result in judgments or settlements that restrict our operations in a manner that materially adversely effects our operations and could result in fines, penalties or awards that could materially impair our financial condition and even threaten our continued operation as a going concern.
We will be subject to foreign government regulation and environmental, health and safety concerns that may adversely affect our business. As our business expands outside of the United States, our operations will be subject to the environmental, health and safety laws of the countries where we do business, including permitting and compliance requirements that address the similar risks as do the laws in the United States, as well as international legal requirements such as those applicable to the transportation of hazardous materials. Depending on the country or region, these laws could be as stringent as those in the U.S., or they could be less stringent or not as strictly enforced. In some countries in which we are interested in expanding our business, such as Mexico and China, the relevant environmental regulatory and enforcement frameworks are in flux and subject to change. Compliance with these requirements will cause our business to incur costs, and failure to comply with these requirements could adversely affect our business.
In the event we are unable to present and operate our AquaRefining process and operations as safe and environmentally responsible, we may face opposition from local governments, residents or public interest groups to the installation and operation of our facilities.
Risks Related to Owning Our Common Stock
The market price of our shares may be subject to fluctuation and volatility. You could lose all or part of your investment. The market price of our common stock is subject to wide fluctuations in response to various factors, some of which are beyond our control. Since January 1, 2020, the reported high and low sales prices of our common stock have ranged from $0.33 to $8.06 through February 22, 2021. The market price of our shares on the NASDAQ Capital Market may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:
•
actual or anticipated variations in our and our competitors’ results of operations and financial condition;
•
changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;
•
development of technological innovations or new competitive products by others;
•
regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products;
•
our sale or proposed sale, or the sale by our significant stockholders, of our shares or other securities in the future;
•
changes in key personnel;
•
success or failure of our research and development projects or those of our competitors;
•
the trading volume of our shares; and
•
general economic and market conditions and other factors, including factors unrelated to our operating performance.
These factors and any corresponding price fluctuations may materially and adversely affect the market price of our shares and result in substantial losses being incurred by our investors. In the past, following periods of market volatility, public company stockholders have often instituted securities class action litigation. If we were involved in securities litigation, it could impose a substantial cost upon us and divert the resources and attention of our management from our business.
If securities or industry analysts do not continue to publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline. The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If industry analysts cease coverage of us, the trading price for our common stock would be negatively affected. If one or more of the analysts who cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, our common stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which might cause our common stock price and trading volume to decline. In addition, independent industry analysts may provide reviews of our AquaRefining technology, as well as competitive technologies, and perception of our offerings in the marketplace may be significantly influenced by these reviews. We have no control over what these industry analysts report, and because industry analysts may influence current and potential customers, our brand could be harmed if they do not provide a positive review of our products and platform capabilities or view us as a market leader.
We have received a notice of delisting for failure to satisfy the Nasdaq continued listing rule concerning the composition of our audit committee. On May 19, 2020, Sushil “Sam” Kapoor resigned from our board of directors, or Board. Mr. Kapoor was one of three members of the audit committee of our Board. As a consequence of Mr. Kapoor’s resignation, we became out of compliance with Nasdaq Listing Rule 5605(c)(2), which requires that the board of directors of a Nasdaq listed company have an audit committee made up of at least three independent directors. On May 19, 2020, we advised The Nasdaq Stock Market LLC of Mr. Kapoor’s resignation, its consequences with regard to compliance with Nasdaq Listing Rules 5605(c)(2) and our intention to regain compliance with Nasdaq Listing Rule 5605(c)(2) in a timely manner. In accordance with Nasdaq Listing Rule 5605(c)(4), we have an automatic cure period in order to regain compliance with Nasdaq Listing Rule 5605(c)(2) until (i) the earlier of our next annual stockholders’ meeting or May 19, 2021; or (ii) if our next annual stockholders’ meeting is held before November 16, 2020, then we must evidence compliance no later than November 16, 2020. We intend to appoint a third independent director to our Board and audit committee, and thereby regain compliance Nasdaq Listing Rule 5605(c)(2), prior to our next annual meeting of stockholders. However, if we are unable to regain compliance with Nasdaq Listing Rule 5605(c)(2) in a timely manner, the Nasdaq will commence suspension and delisting procedures.
A securities class action lawsuit and shareholder derivative lawsuit are pending against us and could have a material adverse effect on our business, results of operations and financial condition. A putative consolidated class action lawsuit and shareholder derivative lawsuit are pending against us and certain of our current and former directors and officers. These lawsuits may divert financial and management resources that would otherwise be used to benefit our operations. Although we deny the material allegations in the lawsuits and intend to defend ourselves vigorously, defending the lawsuits could result in substantial costs. No assurances can be given that the results of these matters will be favorable to us. An adverse resolution of any of these lawsuits could have a material adverse effect on our results of operations and financial condition. In addition, we may be the target of securities-related litigation in the future, both related and unrelated to the existing class action and shareholder derivative lawsuits. Such litigation could divert our management’s attention and resources, result in substantial costs, and have an adverse effect on our business, results of operations and financial condition.
We maintain director and officer insurance that we regard as reasonably adequate to protect us from potential claims; however, we are responsible for meeting certain deductibles under the policies and, in any event, we cannot assure you that the insurance coverage will adequately protect us from claims made. Further, as a result of the pending litigation, the costs of insurance may increase and the availability of coverage may decrease. As a result, we may not be able to maintain our current levels of insurance at a reasonable cost, or at all, which might make it more difficult to attract qualified candidates to serve as executive officers or directors.
Future sales of substantial amounts of our common stock, or the possibility that such sales could occur, could adversely affect the market price of our common stock. We cannot predict the effect, if any, that future issuances or sales of our securities or the availability of our securities for future issuance or sale, will have on the market price of our common stock. Issuances or sales of substantial amounts of our securities, or the perception that such issuances or sales might occur, could negatively impact the market price of our common stock and the terms upon which we may obtain additional equity financing in the future.
We have not paid dividends in the past and have no plans to pay dividends. We plan to reinvest all of our earnings, to the extent we have earnings, in order to pursue our business plan and cover operating costs and to otherwise become and remain competitive. We do not plan to pay any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that we would, at any time, generate sufficient surplus cash that would be available for distribution to the holders of our common stock as a dividend. Therefore, you should not expect to receive cash dividends on our common stock.
Our charter documents and Delaware law may inhibit a takeover that stockholders consider favorable. Provisions of our certificate of incorporation and bylaws and applicable provisions of Delaware law may delay or discourage transactions involving an actual or potential change in control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. The provisions in our certificate of incorporation and bylaws:
•
limit who may call stockholder meetings;
•
do not permit stockholders to act by written consent;
•
do not provide for cumulative voting rights;
•
establish an advance notice procedure for stockholders' proposals to be brought before an annual meeting, including proposed nominations of persons for election to our board of directors, and
•
provide that all vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.
In addition, Section 203 of the Delaware General Corporation Law may limit our ability to engage in any business combination with a person who beneficially owns 15% or more of our outstanding voting stock unless certain conditions are satisfied. This restriction lasts for a period of three years following the share acquisition. These provisions may have the effect of entrenching our management team and may deprive you of the opportunity to sell your shares to potential acquirers at a premium over prevailing prices. This potential inability to obtain a control premium could reduce the price of our common stock.
Our bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with the Company. Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action asserting a claim against us or any our directors, officers or other employees arising pursuant to any provision of the Delaware General Corporation Law or our certificate of incorporation or bylaws, or (iv) any action asserting a claim against us or any our directors, officers or other employees governed by the internal affairs doctrine. This forum selection provision in our bylaws may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or any of our directors, officers or other employees.

ITEM 3. LEGAL PROCEEDINGS
Item 3.
Legal Proceedings
Beginning on December 15, 2017, three purported class action lawsuits were filed in the United Stated District Court for the Northern District California against the Company, Stephen Clarke, Thomas Murphy and Mark Weinswig. On March 23, 2018, the cases were consolidated under the caption In Re: Aqua Metals, Inc. Securities Litigation 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 (“Amended Complaint”), on behalf of a class of persons who purchased the Company’s 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 the Company’s lead recycling operations and conducted deceptive site visits in violation of Section 10(b) of the Securities Exchange Act of 1934 (“Exchange Act”) 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 (“Securities Act”) 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 the Company’s 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’ attorneys’ 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’ 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’ attorneys’ 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. The Company denies that the claims in the Second Amended Complaint have any merit and the Company intends to vigorously defend the action.
Beginning on February 2, 2018, five purported shareholder derivative actions were filed in the United States District Court for the District of Delaware against the Company and certain of its current and former executive officers and directors, Stephen R. 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 In re Aqua Metals, Inc. Stockholder Derivative Litigation, 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 the Company’s 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’ attorneys’ 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.
The Company is not party to any other legal proceedings. The Company may, from time to time, be party to litigation and subject to claims incident to the ordinary course of business. As the Company’s growth continues, it may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect the Company’s future financial position, results of operations or cash flows.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
Item 7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations
General
Aqua Metals (NASDAQ: AQMS) 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™. 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.
We completed the development of our LAB recycling facility at TRIC, 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 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.
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.
As of December 31, 2020, we have received approximately $23.4 million of insurance proceeds from our insurance carriers. Based on our estimates, as of the date of this report, we believe that the replacement value of the equipment and plant lost or damaged in the fire will likely be higher. We have also submitted a significant claim on our business interruption cost recovery. 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. Assets on our balance sheet as of December 31, 2020 that were not affected by the fire total approximately $24.9 million 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. Our policy in place at the time of the fire includes up to $50 million in combined property, equipment and business interruption insurance.
During the first half of 2020, we successfully performed test runs on the first and second iterations of our 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.
Our business model focus is on global licensing opportunities to incorporate AquaRefining in the recycling industry.
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. 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.
During the year ended December 31, 2020, we issued 3,217,426 shares of common stock pursuant to an At the Market Issuance Sales Agreement ("ATM") for net proceeds of $3.7 million.
Results of Operations for the Fiscal Year Ended December 31, 2020 Compared to the Fiscal Year Ended December 31, 2019
Our lead recycling facility was not in production during 2020 due to the fire that occurred in November of 2019 and the acceleration of our licensing strategy. During the year ended December 31, 2020, revenue resulted from the sale of inventory consisting of lead compounds that were generated during pre-fire operations. During the year ended December 31, 2019, product sales consisted of lead bullion, lead compounds and plastics that were generated through the AquaRefining process. The following table summarizes results of operations with respect to the items set forth below for the twelve months ended December 31, 2020 together with the percentage change from the twelve months ended December 31, 2019 for those items (in thousands).

Except for nominal sales of inventory, we did not generate revenue during the twelve months ended December 31, 2020 as there has been not significant production subsequent to the year ended December 31, 2019. The plant was not in production during 2020 except for the operation and testing of our improved Aqualyzers as part of the V1.25 program.
Cost of product sales includes raw materials, supplies and related costs, salaries and benefits, consulting and outside services costs, depreciation and amortization costs, insurance, travel and overhead costs. Cost of product sales decreased approximately 78% for the twelve months ended December 31, 2020, as compared to the twelve months ended December 31, 2019. Cost of product sales decreased during 2020, due to the discontinuation of commercial production at the AquaRefinery.
Research and development cost included expenditures related to the improvement of the AquaRefining technology. During the twelve months ended December 31, 2020, research and development costs decreased approximately 34% from the comparable period in 2019. The decline in research and development cost is primarily the result of staff reduction and management's focus on expediting our transition to a capital light business strategy.
General and administrative expense decreased approximately 53% for the twelve months ended December 31, 2020 compared to the twelve months ended December 31, 2019. The suspension of activities under our Operations, Maintenance and Management Agreement with Veolia, reduced Company payroll and
improvements in nearly all other expense categories drove the decrease. For the twelve months ended December 31, 2019, we had $9.0 million of non-cash expense related to the Veolia agreement.

Insurance proceeds net of related expenses resulted from collection and payment activity that began in 2020 as a result of the November 2019 fire. In connection with our year-end accounting, we recognized a non-cash impairment charge for the year ended December 31, 2020 of $11.7 million, subsequent to an analysis of our fixed assets and a write-down to fair market values. Historically, interest expense has been related primarily to the $5.0 million Interstate Battery convertible note and the $10.0 million note payable to Veritex Community Bank, the successor in interest to Green Bank, amortization of debt issuance costs incurred in connection with both of these notes, as well as an accrual for the USDA guarantee fee on the $10.0 million note to Veritex. On January 24, 2019, we repaid Interstate Battery the outstanding principal and interest on the convertible debt in the amount of $6.7 million. As a result of this debt repayment, we amortized the remaining discount on the note of $2.6 million and remaining deferred financing expenses of $20,000 to interest expense. On December 10, 2020, we retired the loan with Veritex. As part of the loan payoff, we expensed the remaining unamortized loan costs of $0.6 million. In addition, we incurred a prepayment penalty of $0.4 million, which is also included in interest expense. Interest income decreased for the twelve months ended December 31, 2020 compared to the same period in 2019 due to lower cash balances during the year.
Liquidity and Capital Resources
As of December 31, 2020, we had total assets of $35.1 million and working capital of $4.9 million.

Net cash used in operating activities
Net cash used in operating activities for the years ended December 31, 2020 and December 31, 2019 was $11.0 million and $25.2 million, respectively. Net cash used in operating activities during each of these periods consisted primarily of our net loss adjusted for noncash items such as depreciation, amortization, and stock-based compensation charges as well as net changes in working capital. During the year ended December 31, 2020, we recognized an $11.7 million expense for impairment on fixed assets and $0.5 million for the elimination of our asset retirement obligation. During the year ended December 31, 2019, we recognized non-cash payments to Veolia of approximately $9.0 million for shares issued and warrant expense.
Net cash provided by (used in) investing activities
Net cash provided by investing activities for the year ended December 31, 2020 was $6.6 million compared to net cash used in investing activities of $10.6 million for the year ended December 31, 2019. Net cash used in investing activities during each of these periods consists primarily of purchases of fixed assets and insurance proceeds received.
Net cash provided by financing activities
Net cash provided by financing activities for the year ended December 31, 2020 consisted of $3.7 million net proceeds from ATM shares sales. Net cash provided by financing activities for the year ended December 31, 2019 consisted of $29.4 million in net proceeds from two public share offerings, which was partially offset by a $6.7 million payoff of the Interstate Battery convertible note.
As of December 31, 2020, we had total cash of $6.5 million and working capital of $4.9 million. As of the date of this report, we believe that we may require additional capital in order to fund our current level of ongoing costs over the next twelve months and move forward with our capital light licensing strategy. There can be no assurance that we will be able to acquire the necessary funding on commercially reasonable terms or at all. We intend to seek funds through the recovery of potential remaining insurance proceeds and the possible sale of equipment that is not required for our capital light strategy. 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. 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.
Off-Balance Sheet Arrangements
We do not have any off-balance sheet financing arrangements.
Critical Accounting Policies and Significant Judgments and Estimates
Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The preparation of our consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of expenses during the period. 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 estimated asset retirement obligations, the determination of stock option expense, and the determination of the fair value of stock warrants issued. Our actual results could differ from these estimates under different assumptions or conditions.
While our significant accounting policies are more fully described in Note 2 to the consolidated financial statements included in Item 8 of this Annual Report on Form 10-K, we believe that the following accounting policies are the most critical to assist stockholders and investors reading the consolidated financial statements in fully understanding and evaluating our financial condition and results of operations.
Accounts receivable
We sell our products to large well-established companies and extend credit without requiring collateral, based on an ongoing evaluation of the customer’s business prospects and financial condition. In the event that payment of a customer’s account receivable is doubtful, we would reserve the receivable under an allowance for doubtful accounts.
Inventory
Inventory is stated at the lower of cost or net realizable value. Inventory cost is recorded on a first-in, first-out basis using the weighted average method. Net realizable value is determined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.
Property and equipment
Property and equipment are stated at cost net of accumulated depreciation. Depreciation on property and equipment is calculated on the straight-line basis over the estimated useful lives of the assets. Leasehold improvements are depreciated over the shorter of the life of the asset or the remaining term of the lease. We periodically evaluate our property and equipment assets for indications that the carrying amount of an asset may not be recoverable. At December 31, 2020, management reviewed the remaining estimated lives of our long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the period when such determination is made, as well as in subsequent periods. We evaluate the need to record impairment during each reporting period. We determined that the remaining useful lives of the equipment has decreased due to our focus on a capital light strategy. We recognized a $11.7 million impairment during the period. The impairment expense included a write-down of $7.7 million to equipment under construction that was not yet capitalized. In addition, certain other equipment was written down by $4.0 million to fair values, resulting in the acceleration to depreciation for identified assets.
Intangible and other long-lived assets
The intangible assets consist of a patent application contributed to us by five founding stockholders, patent applications for technology developed by us and trademark applications. The useful life of the intangible assets has been determined to be ten years and the assets are being amortized. We periodically evaluate our intangible and other long-lived assets for indications that the carrying amount of an asset may not be recoverable. In reviewing for impairment, we compare the carrying value of such assets to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. When the estimated undiscounted future cash flows are less than their carrying amount, an impairment loss is recognized equal to the difference between the assets’ fair value and their carrying value. In addition to the recoverability assessment, we routinely review the remaining estimated lives of our long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the period when such determination is made, as well as in subsequent periods. We evaluate the need to record impairment during each reporting period. No impairment has been recorded. We determined that the estimated life of the intellectual property properly reflected the current remaining economic life of the asset.
Asset retirement obligations
We have historically recorded the fair value of estimated asset retirement obligations associated with tangible long-lived assets in the period incurred. Retirement obligations associated with long-lived assets are those for which there is an obligation for closures and/or site remediation at the end of the assets’ useful lives. These obligations were initially estimated based on discounted cash flow estimates and are accreted to full value over time through charges to operating expense. In addition, asset retirement costs were capitalized as part of the related asset’s carrying value and are depreciated on a straight-line basis over the assets’ respective useful lives. Due to the change in the primary use of the Company's McCarran, Nevada facility, the Written Determination issued to the Company requiring the Facility Closure Trust deposit was terminated by the NDEP on December 9, 2020. As a result of this termination, the Trust account was closed and the Trustee reimbursed the Company the entire balance of the Trust account. As a result of the elimination of the Trust obligation and the refund of the balance, the original amount of the estimated closure cost that was capitalized and the accumulated accretion were written off.
Revenue Recognition
The Company records revenue recognition in accordance with ASC 606, Revenue from Contracts with Customers. ASC 606 provides a single comprehensive model for the recognition of revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. It requires an entity to recognize revenue when the entity transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASC 606 creates a five-step model that requires entities to exercise judgment when considering the terms of contract(s), which includes (1) identifying the contract(s) with the customer, (2) identifying the separate performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the separate performance obligations, and (5) recognizing revenue as each performance obligation is satisfied. ASC 606 requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including qualitative and quantitative information about contracts with customers, significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract.
Insurance Proceeds
On November 29, 2019, there was a fire in the Aqua Refining area of the TRIC facility. The Company recorded an insurance proceeds receivable balance of $19.9 during the fourth quarter of 2019, which was limited by GAAP accounting standards to the net book value of assets written off as a result of the fire. The insurance proceeds receivable balance has been reduced to zero as insurance payments have exceeded the total established insurance proceeds receivable amount. Any amounts received in excess of that total are reported as other income. As of December 31, 2020, the Company has received $23.4 million in insurance payments as a result of the fire damage. Subsequent to year end, the Company received an additional $0.1 million of insurance proceeds. The Company has also determined that it is probable to receive additional insurance payments.
Research and development
Research and development expenditures are expensed as incurred.
Income taxes
We account for income taxes in accordance with the liability method of accounting for income taxes. Under the liability method, deferred assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying amounts of assets and liabilities and their respective tax bases. The provision for income taxes is comprised of the current tax liability and the changes in deferred tax assets and liabilities. We established a valuation allowance to the extent that it is more likely than not that deferred tax assets will not be recoverable against future taxable income.
We recognize the effect of uncertain income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
Stock-based compensation
We recognize compensation expense for stock-based compensation in accordance with ASC 718 “Compensation - Stock Compensation.” For employee stock-based awards, we calculate the fair value of the award on the date of grant using the Black-Scholes-Merton method for stock options; the expense is recognized over the service period for awards to vest.
The estimation of stock-based awards that will ultimately vest requires judgment and to the extent actual results or updated estimates differ from the original estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised. The Company considers many factors when estimating expected forfeitures, including types of awards, employee class and historical experience.

Operating lease obligations
We lease our Alameda, California and McCarran, Nevada spaces under non-cancelable operating leases, expiring in 2022 and 2021, respectively. On February 4, 2019, we entered into a sublease agreement effective as of February 1, 2019 for the Alameda, California facility. The term of the sublease commenced on February 4, 2019, and ends on May 31, 2022. The above obligations do not include partially offsetting sublease income of approximately $0.7 million for the remainder of the Alameda lease agreement.
Finance lease obligation
We currently maintain one finance lease for equipment. Our finance lease is immaterial to our consolidated financial statements.
Long-term debt
Aqua Metals Reno, Inc. entered into a $10,000,000 loan with Green Bank on November 3, 2015. The term of the loan was twenty-one years. We paid the balance of the loan on December 10, 2020. The current balance consists of amounts due related to the Payment Protection Program (PPP) loans. See Note 11 in the accompanying notes to the consolidated financial statements for additional information.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Item 7A.
Quantitative and Qualitative Disclosures About Market Risk
We do not enter into financial instruments for trading or speculative purposes. Our cash, cash equivalents and restricted cash balances as of December 31, 2020 consisted of cash and cash equivalents. During 2020, our primary exposure to market risk was interest expense related to our debt with Veritex Bank. The interest rate on this loan adjusted on the first day of each calendar quarter equal to the greater of six percent (6%) or two percent (2%) per annum above the minimum prime lending rate charged by large U.S. money center commercial banks as published by the Wall Street Journal. However, we paid off the entire amount due to Veritex in December 2020 and no longer are exposed to this risk. We experience market risk with respect to the volatility of lead commodity prices. The purchase price of our primary raw material used lead acid batteries (used LABs), and the sales price of our lead-based finished products are based on commodity pricing. Due to the relatively short turnaround between the purchase of used LABs and the sale of our finished goods, we believe the risk is minimized.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and
Stockholders of Aqua Metals, Inc. and Subsidiaries:
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Aqua Metals, Inc. and Subsidiaries (collectively the "Company") as of December 31, 2020 and 2019, the related consolidated statements of operations, stockholders' equity and cash flows, for each of the two years in the period ended December 31, 2020, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.
Impairment of Property and Equipment - Refer to Note 5 to the Consolidated Financial Statements
Critical Audit Matter Description
On November 29, 2019, there was a fire in the AquaRefining area of the Company's plant in the Tahoe Reno Industrial Center in McCarran, Nevada. As a result of the fire, during the year ended December 31, 2019, the Company determined that property and equipment that were damaged had become impaired and wrote them down by $22.4 million. During the year ended December 31, 2020, management transitioned the Company's business model from the development of additional Company-owned lead-acid battery recycling facilities to a focus on global licensing opportunities to incorporate AquaRefining in the recycling industry. Due to the shift in the Company's business model, during the year ended December 31, 2020, the Company conducted a review of its property and equipment for impairment and, as a result, recognized an impairment expense of $11.7 million with respect to the write-down of equipment to fair value. The impairment expense included a write-down of $7.7 million to equipment under construction that was not yet capitalized. In addition, certain other equipment was written down by $4.0 million to fair value, resulting in the acceleration of accumulated depreciation for identified property and equipment.
Given these factors and assumptions, the related audit effort to evaluate management's property and equipment impairment adjustments was extensive and required a high degree of auditor judgment.
How the Critical Audit Matter Was Addressed in the Audit
Our principal audit procedures related to the Company's property and equipment impairment methodology included the following:
●
We obtained the Company's impairment analysis and valuation report, selected a sample of property and equipment items and performed the following procedures:
o
Evaluated the facts and circumstances surrounding the impairment analysis for accuracy and reasonableness, including observation of the fire damaged area of the plant.
o
Inquired of management and the operations team in order to obtain an understanding of the strategic shift of the Company's business.
o
Verified the property and equipment included in the impairment analysis were recorded at the proper value before impairment.
o
Verified that the population of property and equipment evaluated was complete.
●
We utilized specialists to perform the following procedures:
o
Evaluated the reasonableness of the assumptions, data, methodology and models used in the valuation report.
o
Performed corroborative calculations for the various analyses, confirming that the methodologies, inputs and calculations appeared accurate.
o
Performed appropriate mathematical checks and benchmarking analyses related to the assumptions, data, methodology and models used in the valuation report.
We have served as the Company's auditor since 2014.

Notes to Consolidated Financial Statements
1.
Organization and Operations
Aqua Metals, Inc. (the “Company”) was incorporated in Delaware and commenced operations on June 20, 2014 (inception). On January 27, 2015, the Company formed two 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 November 29, 2019, 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 November 29, 2019, the Company's business model has transitioned to a focus on global licensing opportunities to incorporate AquaRefining in the recycling industry.
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 April 2017, and through March 31, 2018 substantially all revenue was derived from the sale of lead compounds and plastics. In April 2018, the Company commenced the limited production of lead bullion, including AquaRefined lead. In July 2018, the Company commenced the sale of pure AquaRefined lead in the form of two tonne blocks and in October 2018, the Company commenced the sale of AquaRefined lead in the form of battery manufacturing ready ingots. In November 2018, the Company received official vendor certification from Clarios for its AquaRefined lead and, in December 2018, the Company commenced shipments directly to Clarios owned and partner battery manufacturing facilities. In 2019, the Company operated its demonstration AquaRefinery at commercial quantity production levels and produced over 35,000 AquaRefined ingots by operating the AquaRefinery 24 hours a day and seven days a week for sustained periods of time. The AquaRefining Aqualyzers 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.
During the first half of 2020, the Company successfully performed test runs on the first and second iterations of its Aqualyzer as part of the 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 equipment supply and licensing offerings. In December, 2020, Aqua Metals completed the V1.25L Aqualyzer program on time and under budget, achieving lead production that is 100% greater than the V1.0 Aqualyzer deployed at the AquaRefinery during commercial production in 2018 and 2019. The V1.25L program concluded with a multi-day 24/7 endurance run that ended on December 24th. The doubling of throughput results in a 50% reduction in the number of Aqualyzers needed for equivalent lead production.

The Company generated revenues of $0.1 million and $4.9 million during the years ended December 31, 2020 and December 31, 2019, respectively. The Company had net losses of $25.8 million and $44.8 million for the years ended December 31, 2020 and December 31, 2019, respectively. As of December 31, 2020, the Company’s cash balance was $6.5 million. As of the date of this report, the Company believes it may require additional capital, in order to fund its current level of ongoing costs over the next twelve months and move forward with its capital light licensing strategy.

Summary of Significant Accounting Policies
Basis of presentation and consolidation
The accompanying consolidated financial statements include those of Aqua Metals, Inc. and its subsidiaries, after elimination of all intercompany accounts and transactions. The Company has prepared the accompanying consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”).
Use of estimates
The preparation of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, 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. Actual results could differ from those estimates.
Cash and cash equivalents
The Company considers all highly liquid instruments with original or remaining maturities of ninety days or less at the date of purchase to be cash equivalents. The Company maintains its cash balances in large financial institutions. Periodically, such balances may be in excess of federally insured limits.
Accounts receivable
The Company has traditionally sold its products to large well-established companies and extends credit without requiring collateral, based on an ongoing evaluation of the customer’s business prospects and financial condition. In the event that payment of a customer’s account receivable is doubtful, the Company would reserve the receivable under an allowance for doubtful accounts. As of December 31, 2020, the Company did not have a trade accounts receivable balance and, therefore, has not created any reserve for doubtful accounts. The accounts receivable balance as of December 31, 2020 was related to the return of product to a vendor.
Inventory
Inventory is stated at the lower of cost or net realizable value. Cost is recorded on a first-in, first-out basis using the weighted average method. Net realizable value is determined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company records a write-down, if necessary, to reduce the carrying value of inventory to its net realizable value. The effect of these write-downs is to establish a new cost basis in the related inventory, which is not subsequently written up.
Property and equipment
Property and equipment are stated at cost net of accumulated depreciation. Depreciation on property and equipment is calculated on the straight-line basis over the estimated useful lives of the assets. Leasehold improvements are depreciated over the shorter of the life of the asset or the remaining term of the lease. We periodically evaluate our property and equipment assets for indications that the carrying amount of an asset may not be recoverable. At December 31, 2020, management reviewed the remaining estimated lives of our long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the period when such determination is made, as well as in subsequent periods. We evaluate the need to record impairment during each reporting period. We determined that the remaining useful lives of the equipment has decreased due to our focus on a capital light strategy. We recognized a $11.7 million impairment during the period. The impairment expense included a write-down of $7.7 million to equipment under construction that was not yet capitalized. In addition, certain other equipment was written down by $4.0 million to fair values, resulting in the acceleration to depreciation for identified assets.
Intangible and other long-lived assets
Intangible assets consist of patent applications contributed to the Company by five founding stockholders and patent applications for technology developed by the Company. The useful life of this intellectual property has been determined to be ten years and the assets are being amortized straight-line over this period. The Company periodically evaluates its intangible and other long-lived assets for indications that the carrying amount of an asset may not be recoverable. In reviewing for impairment, the Company compares the carrying value of such assets to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. When the estimated undiscounted future cash flows are less than their carrying amount, an impairment loss is recognized equal to the difference between the assets’ fair value and their carrying value. In addition to the recoverability assessment, the Company routinely reviews the remaining estimated lives of its long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the period when such determination is made, as well as in subsequent periods. The Company evaluates the need to record impairment during each reporting period. As of December 31, 2020, the Company determined that the estimated life of the intellectual property properly reflected the current remaining economic life of the asset.
Asset retirement obligations
The Company has recorded the fair value of estimated asset retirement obligations associated with tangible long-lived assets in the period incurred. Retirement obligations associated with long-lived assets are those for which there is an obligation for closures and/or site remediation at the end of the assets’ useful lives. These obligations are initially estimated based on discounted cash flow estimates and are accreted to full value over time through charges to operating expense. In addition, asset retirement costs have been capitalized as part of the related asset’s carrying value and are depreciated on a straight-line basis over the assets’ respective useful lives. Due to the change in the primary use of the Company's McCarran, Nevada facility, the Written Determination issued to the Company requiring the Facility Closure Trust deposit was terminated by the NDEP on December 9, 2020. As a result of this termination, the Trust account was closed and the Trustee reimbursed the Company the entire balance of the Trust account. As a result of the elimination of the Trust obligation and the refund of the balance, the original amount of the estimated closure cost that was capitalized and the accumulated accretion was written off.
Revenue Recognition
The Company records revenue in accordance with Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers. ASC 606 provides a single comprehensive model for the recognition of revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. It requires an entity to recognize revenue when the entity transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASC 606 creates a five-step model that requires entities to exercise judgment when considering the terms of contract(s), which includes (1) identifying the contract(s) with the customer, (2) identifying the separate performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the separate performance obligations, and (5) recognizing revenue as each performance obligation is satisfied. ASC 606 requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including qualitative and quantitative information about contracts with customers, significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract.
Revenue is generally recognized with the delivery of the Company’s products, primarily hard lead, lead compounds and plastics, to customers. Sales, value add, and other taxes, if any, that are collected concurrent with revenue-producing activities are excluded from revenue as they are subsequently remitted to governmental authorities. Incidental items that are immaterial in the context of the contract are recognized as expense. Freight and shipping costs related to the transfer of the Company’s products to customers are included in revenue and cost of product sales. Payment on invoices is generally due within 30 days of the invoice.
Arrangements with Multiple Performance Obligations
Contracts with customers may include multiple performance obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The Company expects that many of our contracts will have a single performance obligation as the promise to transfer the individual goods or services will not be separately identifiable from other promises in the contracts and therefore, not distinct. For contracts with multiple performance obligations, revenue will be allocated to each performance obligation based on the Company’s best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling prices is based on prices charged separately to customers or expected cost-plus margin. At present, the Company does not have any arrangements with multiple performance obligations.
Significant Judgments
The Company estimates variable consideration for arrangements where the transaction price is not fully determinable until the completion of yield testing. The Company estimates variable consideration at the most likely amount to which it expects to be entitled and includes estimated amounts in revenue to the extent it is probable that a significant reversal of revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Adjustments to revenue is recognized in the period when the uncertainty is resolved. To date, any adjustments to estimates have not been material.
Practical Expedients and Exemptions
The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
Insurance Proceeds
On November 29, 2019, there was a fire in the Aqua Refining area of the TRIC facility. The Company recorded an insurance proceeds receivable balance of $19.9 during the fourth quarter of 2019, which was limited by GAAP accounting standards to the net book value of assets written off as a result of the fire. The insurance proceeds receivable balance has been reduced to zero as insurance payments have exceeded the total established insurance proceeds receivable amount. Any amounts received in excess of that total are reported as other income. As of December 31, 2020, the Company has received $23.4 million in insurance payments as a result of the fire damage. Subsequent to year end, the Company received an additional $0.1 million of insurance proceeds. The Company has also determined that it is probable to receive additional insurance payments.
Research and development
Research and development expenditures are expensed as incurred.
Income taxes
The Company accounts for income taxes in accordance with the liability method of accounting for income taxes. Under the liability method, deferred assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying amounts of assets and liabilities and their respective tax bases. The provision for income taxes is comprised of the current tax liability and the changes in deferred tax assets and liabilities. The Company establishes a valuation allowance to the extent that it is more likely than not that deferred tax assets will not be recoverable against future taxable income.
The Company recognizes the effect of uncertain income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
Fair value measurements
The carrying amounts of cash and cash equivalents, accounts receivable, inventory, prepaid expenses and other current assets, accounts payable, accrued expenses, and deferred rent approximate fair value due to the short-term nature of these instruments. The carrying value of short and long-term debt, and lease liabilities also approximates fair value since these instruments bear market rates of interest or are calculated using market rates of interest. None of these instruments are held for trading purposes.
Fair value is defined as an exit price, representing the amount that would be received upon the sale of an asset or payment to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or liability. A three-tier fair value hierarchy is used to prioritize the inputs in measuring fair value as follows:
Level 1. Quoted prices in active markets for identical assets or liabilities.
Level 2. Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable, either directly or indirectly.
Level 3. Significant unobservable inputs that cannot be corroborated by market data.
The asset or liability’s fair value measurement within the fair value hierarchy is based upon the lowest level of any input that is significant to the fair value measurement.
There are no assets or liabilities that are measured at fair value on a recurring basis at December 31, 2020 or December 31, 2019.
Stock-based compensation
The Company recognizes compensation expense for stock-based compensation in accordance with ASC 718 “Compensation - Stock Compensation.” For employee stock-based awards, the Company calculates the fair value of the award on the date of grant using the Black-Scholes-Merton method for stock options; the expense is recognized over the service period for awards to vest.
The estimation of stock-based awards that will ultimately vest requires judgment and to the extent actual results or updated estimates differ from the original estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised.
Net loss per share
Basic net loss per share is computed by dividing net loss by the weighted average number of vested shares outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common securities, including convertible notes, options and warrants. Potential dilutive common shares include the dilutive effect of the common stock underlying in-the-money stock options and is calculated based on the average share price for each period using the treasury stock method. Under the treasury stock method, the exercise price of an option and the average amount of compensation cost, if any, for future services that the Company has not yet recognized when the option is exercised, are assumed to be used to repurchase shares in the current period.
For all periods presented in this report, convertible notes, stock options, and warrants were not included in the computation of diluted net loss per share because such inclusion would have had an antidilutive effect.
Year Ended December 31,
Excluded potentially dilutive securities (1):
Options to purchase common stock

(1) The number of shares is based on the maximum number of shares issuable on exercise or conversion of the related securities as of the period end. Such amounts have not been adjusted for the treasury stock method or weighted average outstanding calculations as required if the securities were dilutive.
Segment and Geographic Information
Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment, and the Company operates in only one geographic segment.
Concentration of Credit Risk
Revenues from the following customers each represented at least 10% of total revenue for the years ended December 31, 2020 and December 31, 2019.

3.
Revenue recognition
The Company has historically generated revenues by recycling lead acid batteries (“LABs”) and selling the recovered lead to its customers. Primary components of the recycling process include sales of recycled lead consisting of lead compounds, ingoted hard lead and ingoted AquaRefined lead as well as plastics. The Company commenced the shipment of products for sale, consisting of lead compounds and plastics, in April 2017, and through March 31, 2018, all revenue was derived from the sale of lead compounds and plastics. In April 2018, the Company began shipping lead bullion in addition to lead compounds and plastics. In June 2018, the Company began shipping high purity lead from its AquaRefining process.
The Company was not in commercial production in 2020. The nominal revenue generated during the year ended December 31, 2020, resulted from the sale of inventory. Revenue from products transferred to customers at a single point in time with the delivery of the Company’s products to customers accounted for 100% of our revenue during the years ended December 31, 2020 and December 31, 2019.

Asset Retirement Obligation
ASC Topic 410-20, “Asset Retirement and Environmental Obligations, Asset Retirement Obligations” requires the recording of a liability in the period in which an asset retirement obligation (ARO) is incurred, in an amount equal to the discounted estimated fair value of the obligation that is capitalized. In each subsequent fiscal quarter, this liability is accreted up to the final retirement cost. The determination of the ARO is based on an estimate of the future cost to remove and decontaminate the Company’s facility at TRIC upon closure. The estimated fair value of the closure costs was based on vendor quotes to remove and decontaminate the McCarran facility in accordance with the Company’s closure plan as filed with the State of Nevada in its “Application for the Recycling of Hazardous Waste, by Written Determination” in 2016. The discounted estimated fair value of the closure costs was $0.7 million and the obligation was recorded as of March 31, 2017, when the obligation was deemed to have occurred. Offsetting this ARO was an asset retirement cost of the same amount that was capitalized.
The Company entered into a facility closure trust agreement in October 2017 for the benefit of the Nevada Division of Environmental Protection (NDEP), an agency of the Nevada Division of Conservation and Natural Resources. Funds deposited in the trust were to be available, when and if needed, for potential decontamination and hazardous material cleanup in connection with the closure and/or post-closure care of the facility. Due to the change in the primary use of the Company's McCarran, Nevada facility, the Written Determination issued to the Company requiring the Facility Closure Trust deposit was terminated by the NDEP on December 9, 2020. As a result of this termination, the Trust account was closed and the Trustee reimbursed the Company the entire balance of the Trust account. As a result of the elimination of the Trust obligation and the refund of the balance, the original amount of the estimated closure cost that was capitalized and the accumulated accretion were written off. Accretion for the ARO for the year ended December 31, 2019 was $46,000.
10.
Convertible Note
The convertible note payable bore interest at 11% per annum and was due May 24, 2019. The original note discount was calculated as the allocated fair value of the warrants issued in connection with the transaction, which included the issuance of common stock, warrants and the convertible note, as well as the allocated fair value of the embedded conversion feature, subject to limitations on the absolute amount of discount attributable to the convertible notes and its allocated value. The discount was amortized using the effective interest method over the three-year term of the note, maturing on May 24, 2019.
On January 24, 2019, the Company repaid Interstate Battery the outstanding principal and interest on the convertible debt in the amount of $6.7 million. In connection with the payoff, the Company amortized the remaining discount on the note of $2.6 million and remaining deferred financing expenses of $20,000 to interest expense.
11.
Notes Payable
Aqua Metals Reno, Inc. (“AMR”), a subsidiary of Aqua Metals Inc., entered into a $10,000,000 loan with Green Bank on November 3, 2015. The term of the loan was twenty-one years. During the first twelve months, only interest was payable and thereafter monthly payments of interest and principal were due. The interest rate adjusted on the first day of each calendar quarter to the greater of six percent (6%) or two percent (2%) per annum above the minimum prime lending rate charged by large U.S. money center commercial banks as published in the Wall Street Journal. The terms of the Loan Agreement contained various affirmative and negative covenants. Among them, AMR was required to maintain a minimum debt service coverage ratio of 1.25 to 1.0 (beginning with the twelve-month period ending March 31, 2017), a maximum debt-to-net worth ratio of 1.0 to 1.0 and a minimum current ratio of 1.5 to 1.0. AMR was in compliance with all but the minimum debt service coverage ratio covenant as of and for each of the calendar quarters in the period March 31, 2017 through September 30, 2020. AMR obtained a waiver for the minimum debt service coverage ratio covenant for each of the aforementioned calendar quarters.
The net proceeds of the loan were used for the construction of the Company’s lead acid recycling operation in McCarran, Nevada. Collateral for this loan was AMR’s accounts receivable, goods, equipment, fixtures, inventory, accessions and a certificate of deposit in the amount of $1,000,000. The certificate of deposit is reported in "Other Assets" in the condensed consolidated balance sheet. The loan was guaranteed by the United States Department of Agriculture Rural Development (“USDA”), in the amount of 90% of the principal amount of the loan. The Company paid a guarantee fee to the USDA in the amount of $270,000 at the time of closing and was required to pay to the USDA an annual fee in the amount of 0.50% of the guaranteed portion of the outstanding principal balance of the loan as of December 31 of each year. The costs associated with obtaining the Green Bank loan of $0.8 million were recorded as a reduction to the carrying amount of the note and were being amortized as interest expense over the twenty-one year life of the loan. Amortization of the deferred financing costs was $36,000 for both of the years ended December 31, 2020 and December 31, 2019, respectively.
On December 10, 2020, the Company retired the loan with Veritex Community Bank ("Veritex"), the successor in interest to Green Bank. AMR utilized insurance proceeds including $7.9 million held in an escrow account at Veritex as well as the $1.0 million certificate of deposit held by Veritex, as collateral for the note, to pay the balance of the loan. As part of the loan payoff, the Company expensed the remaining unamortized loan costs of $0.6 million. In addition, the Company incurred a prepayment penalty of $0.4 million, which is also included in interest expense.
On May 7, 2020, the Company received loan proceeds in the amount of approximately $332,000 under the Paycheck Protection Program (“PPP”). The PPP, established as part of the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), provided 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 prescribed period.
The unforgiven portion of the PPP loans are now payable over five years at an interest rate of 1%, with a deferral of payments until September of 2021. The Company believes it has used the loan proceeds for purposes consistent with the PPP requirements and has applied for loan forgiveness. Subsequent to December 31, 2020, one of the Company's two PPP loans for $131,000 was forgiven. The Company believes the remaining PPP loan will also qualify for forgiveness. However, there is no assurance that the Company will be eligible for forgiveness of the remaining outstanding loan, in whole or in part.

Leases
The Company currently maintains one finance lease for equipment and two operating leases for real estate. Our finance lease is immaterial to our consolidated financial statements. The Company's operating leases have terms of 76 and 42 months and include one or more options to extend the duration of the agreements. These operating leases are included in "Other assets" on the Company's December 31, 2020 consolidated balance sheet and represent the Company's right to use the underlying assets for the term of the leases. The Company's obligation to make lease payments are included in "Lease liability, current portion" and "Lease liability, non-current portion" on the Company's December 31, 2020 consolidated balance sheet. The Company recognized sublease income of $433,000 and $359,000 for the twelve months ended December 31, 2020 and December 31, 2019, respectively.
Based on the present value of the lease payments for the remaining lease term of the Company's existing leases, as of December 31, 2020, total right-of-use assets were approximately $0.7 million and operating lease liabilities were approximately $0.8 million. As of December 31, 2019, total right-of-use assets were approximately $1.2 million and operating lease liabilities were approximately $1.4 million. The right-of-use assets are reported in "Other Assets" in the condensed consolidated balance sheet.

Stock-based compensation
In 2014, the Board of Directors adopted the Company’s stock incentive plan (the “2014 Plan”). The 2014 Plan was most recently amended and restated effective as of the Company’s 2017 Annual Stockholders’ Meeting. A total of 2,113,637 shares of common stock was authorized for issuance pursuant to the 2014 Plan at the time of its most recent amendment and restatement in 2017. The 2014 Plan provides for the following types of stock-based awards: incentive stock options; non-statutory stock options; restricted stock; and performance stock. The 2014 Plan, under which equity incentives may be granted to employees and directors under incentive and non-statutory agreements, requires that the option price may not be less than the fair value of the stock at the date the option is granted. Option awards are exercisable until their expiration, which may not exceed 10 years from the grant date.
In 2019, the Board of Directors adopted the Company’s stock incentive plan (the “2019 Plan”).

A total of 11,500,000 shares of common stock was authorized for issuance pursuant to the 2019 Plan. The 2019 Plan provides for the following types of stock-based awards: incentive stock options; non-statutory stock options; restricted stock; and performance stock. The 2019 Plan, under which equity incentives may be granted to employees and directors under incentive and non-statutory agreements, requires that the option price may not be less than the fair value of the stock at the date the option is granted.

The risk-free interest rate assumption was based on the United States Treasury’s zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The weighted-average expected life of the options was calculated using the simplified method as prescribed by the Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin No. 107 and No. 110 (“SAB No. 107 and 110”). This decision was based on the lack of relevant historical data due to the Company’s limited historical experience. In addition, due to the Company’s limited historical data, the estimated volatility also reflects the application of SAB No. 107 and 110, using the weighted average of the Company’s historical volatility and the historical volatility of several unrelated public companies within the recycling industry. Forfeitures are recognized as they occur.

Based on the available objective evidence at this time, management believes that it is more likely than not that the net deferred tax assets of the Company will not be realized. Accordingly, management has applied a full valuation allowance against net deferred tax assets at both December 31, 2020 and December 31, 2019. The net valuation allowance increased by approximately $4.0 million during the year ended December 31, 2020. The increase in net valuation allowance primarily relates to net operating losses generated during 2020.
The Company has Federal and California net operating loss carryforwards of approximately $118.2 million and $4.3 million, respectively, which will begin to expire in December 31, 2034 for Federal and California purposes.
Utilization of the Company’s net operating loss may be subject to substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation could result in the expiration of net operating loss carryforwards prior to utilization.
At December 31, 2020, the Company had research and development credits carryforward of approximately $0.2 million and $0.5 million for Federal and California income tax purposes, respectively. If not utilized, the Federal research and development credits carryforward will begin to expire in December 31, 2034. The California credits can be carried forward indefinitely.
The Company’s policy is to account for interest and penalties as income tax expense. As of December 31, 2020, the Company had no interest related to unrecognized tax benefits. No amounts of penalties related to unrecognized tax benefits were recognized in the provision for income taxes.
The Company maintains liabilities for uncertain tax positions. These liabilities involve considerable judgement and estimation and are continuously monitored by management based on the best information available, including changes in tax regulations, the outcome of relevant court cases, and other information. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits as income tax expense. At December 31, 2020, the Company’s total amount of unrecognized tax benefit was approximately $0.2 million, none of which will affect the effective tax rate, if recognized. The Company does not expect its unrecognized benefits to change materially over the next twelve months.
The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted on March 27, 2020. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side payroll tax, Paycheck Protection Program, net operating loss carryback periods, and modifications to the net interest deduction limitations. The most significant impact to the Company from the CARES Act relates to the Paycheck Protection Program and deferment of employer side payroll tax.
The Company files income tax returns with the United States federal government and the State of California. The Company’s tax returns for all prior years from the Company's inception in 2014 remain open to audit for Federal and California purposes.
17.
401(k) Savings Plan
The Company maintains a defined-contribution savings plan under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”). The 401(k) Plan covers all employees who meet defined minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pretax or after tax basis. As of December 31, 2020, the Plan did not provide for employer matching contributions.

Subsequent Events
The Company has evaluated subsequent events through the date which the consolidated financial statements were available to be issued.
Paycheck Protection Program Loan
On January 9, 2021, one of the Company's two Paycheck Protection Program ("PPP") loans for $131,000 was fully forgiven by the Small Business Administration. The PPP loans are forgivable if the borrower uses the loan proceeds for eligible purposes, including payroll, benefits, rent and utilities, and maintains its payroll levels. The Company believes the remaining PPP loan will also qualify for forgiveness. However, there is no assurance that the Company will be eligible for forgiveness of the remaining outstanding loan, in whole or in part.
At the Market Share Issuance
Subsequent to the year ended December 31, 2020, the Company issued 1,827,635 shares of common stock pursuant to the At The Market Issuance Sales Agreement for net proceeds of $7.0 million.
Agreements with LINICO Corporation
On February 15, 2021, the Company entered into a series of definitive agreements with LINICO Corporation, a Nevada corporation, or LiNiCo, pursuant to which the Company leased, with an option to purchase, the Company's recycling facility at the Tahoe Reno Industrial Center, or TRIC, located in McCarran, Nevada, and acquired an approximately 11% equity interest in LiNiCo.
Industrial Lease and Option to Purchase Agreement
The Company have entered into an Industrial Lease Agreement with LiNiCo dated February 15, 2021 pursuant to which the Company has leased to LiNiCo our 136,750 square foot recycling facility at TRIC. The lease commences April 1, 2021 and expires on March 31, 2023. During the lease term, LiNiCo has the option to purchase the land and facilities at a purchase price of $14.25 million if the option is exercised and the sale is completed by October 1, 2022 and $15.25 million if the option is exercised and the sale is completed after October 1, 2022 and prior to March 31, 2023. The purchase option is subject to LiNiCo’s payment of a nonrefundable deposit of $1.25 million by October 15, 2021 and a second nonrefundable deposit of $2 million by November 22, 2022, both of which will be applied towards the purchase price. The lease agreement is a triple-net lease pursuant to which LiNiCo will be responsible for all fixed costs, including maintenance, utilities, insurance, and property taxes. The lease agreement provides for LiNiCo’s monthly lease payments starting at $68,000 per month and increasing to $100,640 in the last six months of the lease. The lease agreement allows the Company to retain the use of a portion of the facility for the Company's ongoing research and development activities, including operation of the lab and the use of office space.
With respect to the portion of the facility that was damaged in the November 2019 fire, consisting of approximately 30,000 square feet, the Company is obligated to complete the clean-up of the damaged area, at the Company's expense, by July 31, 2021 and repair all damage to the damaged area, at our expense, by November 15, 2021. With regard to the equipment on-site at TRIC, the Company has granted LiNiCo the right of first offer to purchase any equipment the Company offers for sale. The lease agreement contains customary representations, warranties and indemnities on the part of both parties.
Investment Agreement
On February 15, 2021, the Company entered into a Series A Preferred Stock Purchase Agreement with LiNiCo that provides for the Company's issuance of 375,000 shares (“Aqua Shares”) of the Company's common stock in consideration of LiNiCo’s issuance 1,500 shares of its Series A Preferred Stock, at a stated aggregate value of $1,500,000, along with a three-year warrant (“Series A Warrant”) to purchase an additional 500 shares of LiNiCo Series A Preferred Stock at an exercise price of $1,000 per share. The 1,500 shares of the Series A Preferred Stock represents approximately 11% of LiNiCo common stock on a fully diluted basis, before giving effect to the Company's exercise of the Series A Warrant or any other outstanding warrants of LiNiCo.
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 one 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 $1,000 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 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. 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.
The Series A Preferred Stock Purchase Agreement includes customary representations, warranties, and covenants by LiNiCo and the Company, and an indemnity from the Company in favor of LiNiCo.
In the event that LiNiCo’s sale of the initial 281,250 of the Aqua Shares results in net proceeds to LiNiCo of less than $1,500,000, the Company will be required to pay LiNiCo the difference in cash. If the sale of the 281,250 Aqua Shares results in net proceeds to LiNiCo of more than $1,500,000, such excess proceeds shall be applied to the exercise of the Company's Series A Warrant. The balance of the 93,750 Aqua Shares will be held by LiNiCo for six months after the closing, and if the net proceeds received by LiNiCo from the sale of the 93,750 Aqua Shares, plus the net proceeds from the sale of the initial 281,250 of the Aqua Shares (including any shortfall payment by the Company), is greater than $2,000,000, such excess shall be paid back to the Company.
In connection with the investment transactions, the Company also entered into an Investors Rights Agreement and a Voting Agreement, each dated February 15, 2021, pursuant to which LiNiCo granted the Company customary demand and piggyback registration rights, information rights and the right to nominate one person to the LiNiCo board of directors as long as the Company is the owner of at least 10% of the LiNiCO common stock on a fully-diluted basis.
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 Chief Financial Officer, Judd Merrill, is a member of the board of directors of Comstock Mining.

ITEM 9A. CONTROLS AND PROCEDURES
Item 9A.
Controls and Procedures
(a) Evaluation of Disclosure Controls and Procedures.
Our management, with the participation of our chief executive officer and chief financial officer evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based upon that evaluation, our management, including our chief executive officer and chief financial officer, concluded that for the reasons described below our disclosure controls and procedures were effective as of December 31, 2020 in ensuring all material information required to be filed has been made known in a timely manner.
(b) Changes in internal control over financial reporting.
There were no changes to our internal control over financial reporting, as defined in Rules 13a-15(f) under the Exchange Act that occurred during the fiscal quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
(c) Management’s report on internal controls over financial reporting.
Our management is responsible for establishing and maintaining adequate internal controls over financial reporting, as defined under Rule 15a-15(f) under the Exchange Act. Our management has assessed the effectiveness of our internal controls over financial reporting as of December 31, 2020 based on the framework established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements. An internal control material weakness is a significant deficiency, or aggregation of deficiencies, that does not reduce to a relatively low level the risk that material misstatements in financial statements will be prevented or detected on a timely basis by employees in the normal course of their work. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2020, and based on that evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2020.
This report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to the rules of the Securities and Exchange Commission that permit us to provide only management’s report in this annual report.
