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 metals through a novel, proprietary and patent-pending process that we developed and named “AquaRefining”. Since our formation, we have focused our efforts initially on the development and testing of our AquaRefining process for lead acid batteries, or LAB, and advanced that process by building a demonstration plant located in the Tahoe Reno Industrial Center in McCarran, Nevada (“TRIC”). We also have developed a business plan which includes equipment supply services and licensing of the AquaRefining technology to recyclers and began research and development on using the AquaRefining process on lithium ion batteries (LIB) at our Innovation Center also located at TRIC.
We completed the development of our first LAB recycling facility at TRIC and commenced production of battery breaking and limited operations during the first quarter of 2017. From April 2017 through April 2018, we commenced the shipment of products for sale, consisting of lead compounds as well as plastics and limited production of lead bullion, including AquaRefined lead. During 2018, we commenced the sale of pure AquaRefined lead in the form of two tonne blocks and 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 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 Aqualyzers in operation 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 Company and the insurance carriers agreed on a total claim of $30.25 million which was paid in full by the carriers. Plant clean-up and repair of fire damaged areas began in 2021 and were substantially completed by the end of the year.
Following the November 2019 fire, we have been engaged in the pursuit of our business strategy that is based on the pursuit of licensing opportunities within the lead battery recycling marketplace. We believe our business strategy will require less space and less equipment and focus on the needs of our future licensees. The capital light strategy is based on the pursuit of licensing opportunities within the battery recycling marketplace without maintaining and operating a capital-intensive battery 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.
Our strategy also includes an expansion into lithium-ion battery recycling. In addition to research and development work, we enhanced our strategy by investing in LINICO Corporation (“LINICO”). We reached a lease-to-buy agreement with LINICO for the Aqua Metals' AquaRefining facility. In February 2021, we announced a strategic investment in LINICO Corporation of up to $2 million to be paid in Aqua Metals shares and cash for a 10% ownership in LINICO as part of our strategy to strengthen growth by potentially applying AquaRefining intellectual property to lithium-ion battery recycling while meeting our lead recycling commercial guidance.
Part of the efforts related to our business plan during 2020 and 2021 included additional improvements related to our existing technology. 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 consisted of three iterations that were classified as V1.25a, V1.25b and the final iteration, V1.25L. 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. In August 2021, we announced the completion of the V1.5 Aqualyzer. This latest Aqualyzer configuration has now achieved lead production that is over 300% greater than the V1.0 Aqualyzer deployed at the AquaRefinery during commercial production in 2018 and 2019. These results are expected to positively impact capital and operating expenses for the Company’s equipment supply and technology licensing customers. The increase in throughput results in a reduction of more than 60% in the number of Aqualyzers needed for equivalent lead production delivered by the V1.0 model, reducing capital and labor and footprint requirements. This latest iteration has also increased electrical efficiency to 97%, which further improves operating costs. In July 2021, we signed our first agreement with ACME Metal Enterprise to deploy AquaRefining technology and equipment which was shipped in early January 2022 to commence the implementation. ACME Metal Enterprise has long running relationships supplying specialized alloys to some of the largest battery manufacturers in the world based in the APAC region. One of the goals of the deployment is to further advance a direct to oxide battery manufacturing process which would eliminate the costly and energy intensive melting and ingotization process and rather take that ultrapure material right from the Aqualyzers to battery oxide production. We believe that our AquaRefining technology is a commercially attractive proposition in the hands of battery recyclers, who also typically have access to lower cost feedstock, established offtake contracts and ability to process all materials on site.
In August 2021, we announced that we had established an Innovation Center focused on applying our proven technology to lithium-ion battery recycling research and development and prototype system activities. Our strategic decision to apply our proven clean, closed-loop hydrometallurgical and electro-chemical recycling experience to lithium-ion battery recycling is designed to meet the growing demand for critical metals driven by the global transition to electric vehicles, growth in Internet data centers, and alternative energy applications including solar, wind, and grid-scale storage.
In November 2021, Aqua Metals and LINICO signed a collaboration agreement which sets the parameters for future research and development cooperation, as both companies expand into lithium-ion battery recycling and advance our technologies designed to recycle lithium-ion batteries cost-effectively and sustainably. Aqua Metals and LINICO plan to source the necessary lithium-ion feedstock from battery manufacturing scrap and end-of-life cells from various sources, including electric vehicle battery suppliers interested in participating in the eco-network the two companies announced in 2021. LINICO will process the feedstock into high-quality black mass utilizing its proprietary process. The resulting black mass will be used as input feedstock for Aqua Metals’ AquaRefining pilot cells intended to create high purity metals such as nickel, cobalt, and copper as well as other compounds.
Unless otherwise indicated, the terms “Aqua Metals,” “Company,” “we,” “us,” and “our” refer to Aqua Metals, Inc. and its wholly owned subsidiaries.
All references in this report to “ton” or “tonne” refer to a metric ton, which is equal to approximately 2,204.6 pounds.
Overview
Aqua Metals is seeking to reinvent lead and other metal recycling with its patented and patent pending AquaRefining™ technology. Aqua Metals is focused on developing cleaner and safer metals recycling through innovation. We believe our Innovation Center can expand the development of breakthrough technologies for sustainable metal recycling that can deliver high-value critical minerals back into the manufacturing supply chain while reducing emissions and toxic byproducts and creating much safer work environments.
Unlike smelting, AquaRefining is a room temperature, water-based process. Aqua Metals has invested in breakthrough metals recycling methodologies that we believe are environmentally responsible, economically competitive, and will help retain critical strategic metals within the U.S. while lowering reliance on unsafe and toxic mining operations. Since 2015, Aqua Metals has developed breakthrough metal recycling technologies that utilize a clean, closed-loop process that can produce ultra-high purity metal. AquaRefining delivers raw materials back into the manufacturing supply chain while reducing emissions and toxic byproducts and creating a safer work environment. The patented AquaRefining modular systems have already demonstrated how they can reduce environmental impact and scale lead-acid battery recycling capacity.
AquaRefining for lead 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 recent years, tightening emissions regulations have forced many U.S. smelters to close.
Lead is an integral component in over a billion electrical storage devices used across the globe, including every car and truck, hybrid and electric vehicle. Lead-based batteries provide backup power for hospitals, electrify households, and are the primary energy storage mode for buildings, data centers, and telecom. Lead is a finite resource with rising demand. The lead acid battery market is expected to grow from $46.6 billion in 2015 to $85.5 billion in 2025. Lead batteries are currently the only 100% recyclable batteries available and 80% of the lead used to manufacture new batteries is recycled.
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 additional “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 less polluting LAB recycling processes.
The Lithium Battery Market
According to our sources, including Goldman Sachs, the global lithium-ion battery market was assessed at approximately USD $
billion in 2020 and is expected to grow at a compound annual growth rate (CAGR) of 19.0% from 2020 to 2028. The growth of the market is being driven by the growing demand for the lithium-ion battery in Electric Vehicles (EVs) and grid storage which offers lightweight high-energy density solutions. The market is also being influenced by increased registration of EVs and a reduction in the price of the lithium-ion battery. Costs have been driven down a long way since 2010, when battery prices were $1,100/kWh, representing a 90% drop over ten years to about $110/kWh today. Rechargeable battery technologies are becoming key to moving from a fossil-fuel driven economy to an electrified world powered by renewable energy that can be stored.
More than 15 million tons of lithium-ion batteries are expected to retire between now and 2030. All major car manufacturers are working on providing electric vehicles and some are moving most of the future production to electric only vehicles.
Lithium Batteries
EV batteries are powered by a battery pack made up of individual cells. Each cell has 4 components: the cathode, anode, separator, and electrolyte. Lithium-ion batteries use different raw materials for each of the components. The most common material used for the anode is graphite. The most widely used metals for the cathode is metal oxides that are combinations of lithium, cobalt, nickel, manganese, and aluminum. The electrolyte is generally made using acidic salts and solvents such as sulfuric acid and there are also solid-state silicon based alternatives on the horizon. The separator is usually created using a porous, polyolefin material like polyethylene or polypropylene.
Lithium-ion battery recycling is the method of taking EV batteries and splitting it into its components, ultimately into the original raw materials (lithium, nickel, cobalt, etc.) that can be reused in new batteries. While making lithium-ion batteries for EVs is important to address climate change, the batteries themselves are harmful to the environment if left in landfills or burned. Currently, 5-7% of lithium-ion batteries are recycled and that must get close to 100% both to avoid another environmental catastrophe and to recapture the critical minerals in those spent batteries to feed the massive demand growth curve. Battery recycling helps address this problem, but current pyro-based battery recycling technology (smelting) also creates harmful emissions, potentially creating new climate problems faster than they are being solved. There are alternative hydro-based technologies being attempted but they are not yet proven and rely on older methodologies that are known to create significant waste streams which have their own negative environmental and economic impacts.
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 through a continuous process that is suitable for use in next generation LAB production.
The AquaRefining process begins with the processing of crushed used batteries either in the form of paste (for LAB) or, in the future, black mass (for LIB). The active materials are first processed to remove sulfur and then dissolved in our solvent. Metals are plated from the solvent using our patented and patent-pending process allowing the solvent to be reused.
Our AquaRefining process can generate 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. We also believe that our AquaRefining process can be used to generate metals, such as nickel and cobalt from lithium-ion recycled batteries.
A significant benefit of our AquaRefining process is that it is capable of producing higher yields of higher purity thus higher value 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 called PureMetrics 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 battery recycling operations with less regulatory cost and burden than smelting operators due to the nature of our process. One of our key initiatives is and 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 and lithium-ion recycling industry from one which is based solely on smelting to one which is either supplemented or produced solely by AquaRefining. 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 and other battery metals produced. We are currently focused on licensing our technology for lead and developing our solution for lithium-ion batteries.
The market for lead and other lithium-ion batteries are 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 battery recycling facilities, both directly and in association with third parties through joint ventures, licensing, and direct sales. We intend to license our lead battery technology to multiple existing battery recyclers. For example, in July 2021 we signed our first agreement with ACME Metal Enterprise to deploy AquaRefining technology and equipment which was shipped in early January 2022 to commence the implementation. We intend to continue to develop our Aqua Refining technology for the recycling of lithium-ion batteries and the licensing of such technology to parties in the LIB industry. In August 2021, we announced that we had established an Innovation Center focused on applying our proven technology to lithium-ion battery recycling research and development and prototype system activities. Our strategic decision to apply our proven clean, closed-loop hydrometallurgical and electro-chemical recycling experience to lithium-ion battery recycling is designed to meet the growing demand for critical metals driven by the global transition to electric vehicles, growth in Internet data centers, and alternative energy applications including solar, wind, and grid-scale storage. In November 2021, Aqua Metals and LINICO signed a collaboration agreement which sets the parameters for future research and development cooperation, as both companies’ expand into lithium-ion battery recycling and advance our technologies designed to recycle lithium-ion batteries cost-effectively and sustainably. Aqua Metals and LINICO plan to source the necessary lithium-ion feedstock from battery manufacturing scrap and end-of-life cells from various sources, including electric vehicle battery suppliers interested in participating in the eco-network the two companies announced in 2021. LINICO will process the feedstock into high-quality black mass utilizing its proprietary process. The resulting black mass will be used as input feedstock for Aqua Metals’ AquaRefining pilot cells intended to create high purity metals such as nickel, cobalt, and copper as well as other compounds.
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, particularly in the more regulated jurisdictions where environmental and worker safety practices are evolving towards improving both conditions.
Secondary competition comes from other alternatives to lead smelting that are electro-chemical 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.
Our development of recycling technology for lithium-ion batteries is a unique approach to extracting the high-value metals compared to the array of other potential solutions under development. Currently, smelting is the only commercially proven process for recycling Lithium-ion batteries. The smelting process utilizes multiple high emissions steps to produce battery ready materials. Over the next decade and beyond, when the volume of used batteries becomes significant, smelting will likely not be a viable solution due to the negative environmental impact and likelihood of regulatory restrictions on emissions. The other technologies currently under development utilize a predominately hydrometallurgical approach that consumes significant amounts of chemicals to extract the metals resulting in high cost and excessive waste streams. Our approach is a hybrid of hydrometallurgical and electrowinning processes similar to the process we have commercialized for lead, we call it “Li AquaRefining”. We believe, and early R&D supports, that Li AquaRefining requires less chemicals, produces less waste streams, and creates higher purity products at a lower cost as compared to both smelting and standard hydrometallurgy.
The lithium-ion battery recycling market is significantly different from that of the lead recycling market in that it is a nascent industry. With no predominant technology to displace, our goal is to enable new and existing recyclers across the globe with Li AquaRefining as a best-in-class solution for meeting the supply chain demands of the lithium-ion battery industry as well as meeting the environmental needs of the planet and the corporations seeking to achieve net zero emissions.
Licensing of our Technology
Our recycling facility located at Tahoe-Reno Industrial Center 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, with 82 patents issued or allowed and 54 patent applications pending in the U.S. and internationally for lead and other metals.
In July 2021, we signed our first agreement with ACME Metal Enterprise to deploy AquaRefining technology and equipment, which was shipped in early January 2022 to commence the implementation. We believe that our AquaRefining technology will be a commercially attractive proposition in the hands of battery recyclers, who typically have access to lower cost feedstock and ability to process all materials on site through a furnace.
We have been engaged in the pursuit of a business 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.
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 8 US patents, 63 international patents, and 3 allowances (two international, one US). In addition to the US patents, we have international patents/allowances in the African Regional Intellectual Property Organization, African Intellectual Property Organization, Australia, Canada, Chile, China, the Eurasian Patent Organization, European Union, Honduras, India, Indonesia, Japan, Malaysia, Mexico, Peru, South Korea, South Africa, Ukraine, and Vietnam. We also have 56 US and foreign patent applications pending with patent applications pending in 21 additional non-US jurisdictions across eight 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 14 foreign countries)
•
AQUAREFINING (US and 10 foreign countries)
•
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 and Lithium based batteries. While the reclamation process itself is generally not subject to federal permitting requirements, depending on how any particular operation is structured, our facilities and the facilities of 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 batteries 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, acids, and other metals involved in 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, acids, and other metals related to lithium batteries 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 South America, Taiwan 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 and in February 2021 we entered into a triple-net lease-to-buy agreement with respect to TRIC. 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 in part from cash on hand 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.
We have initiated the research and development of the application of our AquaRefining technology to the recycling and recovery of lithium-ion batteries, however there can be no assurance that our efforts will be successful. In September 2021, we announced the establishment of our Innovation Center, in McCarran, Nevada, focused on applying our AquaRefining technology to lithium-ion battery recycling research and development and prototype system activities. Earlier in 2021, we filed a provisional patent for recovering high-value metals from recycled lithium-ion batteries to complement the patents for AquaRefining. Based on early phase testing, we believe we may be able to apply our AquaRefining methodology, used for plating ultra-high purity lead, to plating the metals found in lithium-ion batteries such as cobalt, nickel, and copper. Lithium and manganese will be recovered in other forms. However, we have only recently begun to conduct research and development in the recycling of lithium-ion batteries, and there can be no assurance that our efforts will be successful or that we will be able to conduct the recycling and recovery of the high value metals from lithium-ion batteries on a commercial scale.
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, and, subject to our successful research and development, lithium-ion batteries, including ACME Metal Enterprise Co., Ltd., among others. In July 2021, we entered into an agreement with ACME Metal Enterprise Co., Ltd to deploy and potentially license our AquaRefining equipment at ACME’s LAB recycling facility in Keelung, Taiwan. The agreement provides for a phased deployment of our AquaRefining technology at ACME’s Taiwan facility, the joint development of processing AquaRefined briquettes into battery ready oxide material and potentially an exclusive license of our AquaRefining technology to ACME for all of Taiwan. Although we are currently seeking to negotiate agreements with others, as of the date of this report, we have not entered into any such licensing, joint venture or strategic alliance agreements, apart from our agreement with ACME, 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. From inception through December 31, 2021, we generated a total of $11.7 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, 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, entered into a lease-to-buy agreement with respect to TRIC and have shifted our business model to focus exclusively on the licensing of our AquaRefining technology to partners engaged in LAB recycling and, subject to our successful research and development, lithium-ion batteries. 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 ACME Metal Enterprise Co., Ltd and other recyclers of LABs; and
•
our ability to realize the expected benefits of our strategic partnerships and successfully apply our AquaRefining technology to the plating of high value metals found in lithium-ion batteries, including cobalt, nickel, and copper.
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, 2021, we had total cash of $8.1 million and working capital of $8.4 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 licensing strategy. We intend to acquire the necessary capital though the possible sale of certain equipment and assets at TRIC. However, there can be no assurance that we will be able to 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 V1.5 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.
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 and, subject to our successful research and development, lithium-ion batteries 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 or lithium-ion batteries 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 or lithium-ion batteries 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 or lithium-ion batteries using our processes, there can be no assurance that the AquaRefined lead or other recycled metals 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. Further, while we believe we may be able to apply our AquaRefining methodology to plating the metals found in lithium-ion batteries, such as cobalt, nickel, and copper, we have only recently begun to conduct research and development in the recycling of lithium-ion batteries, and there can be no assurance that our efforts will be successful or that we will be able to conduct the recycling and recovery of the high value metals from lithium-ion batteries on a commercial scale.
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. Further, we have not engaged in any commercial operations in the area of recycling of lithium-ion batteries. There can be no assurance that our licensees will be able to produce AquaRefined lead or high value metals from lithium-ion batteries 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, 10316420, 10340561, 10665907, 10689769, 10793957, 11028460, 11072864, allowed 20190267681), Canada (2930945, 2968064, 3007101, allowed 2986022), China (107849634, 108603242, 109183069, 201480071929.1, ZL201580062811.7, ZL201680041571.7, ZL201680041600.X), Europe (3072180, 3221918, 3294916, 3294929, 3483305), Brazil (BR 11 2016 011396-9, BR 11 2017 024433-0), Eurasia (32371, 35532, 36722), South Africa (2016/04083, 2017/08454, 2017/08455, 2017/04123, 2018/04384), South Korea (10-1739414, 10-1882932, 10-1926033, 10-2096976, 10-2242697, 10-2274210, 10-2310653), Honduras (80-2019), India (318321, 364173, 369304), Indonesia (IDP000061176, IDP000066550, IDP000074882, IDP000077702), Japan (6173595, 6592088, 6775006, 6805240, 6861773, 6944453), Malaysia (MY-181071-A, MY-185652-A), Mexico (357027, 387016), OAPI (17808, 19078, 18736), Peru (649-2016), Ukraine (118037, 119580, 124142, 124145, 124523), Vietnam (22588, 1-2017-05043 allowed) Australia (2014353227, 2015350562, 2016260407, 2016260408, 2016362502, 2017213449), ARIPO (AP4995, AP 5559, AP 5946), and Chile (61.519, 62.308).
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.
Our agreement with Clarios has been terminated. In February 2017, we entered into 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. In September 2021, Clarios elected to terminate the equipment supply agreement.
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 $2,429 per tonne in August 2021 to a low of $1,961 per tonne in March 2021 because of fluctuations in the market. Lead price per tonne was approximately $2,305 at the end of December 2021. Our business will be highly dependent on the economic and market conditions in each of the geographic areas in which we operate. These conditions affect our business by reducing the demand for LABs and decreasing the price of lead in times of economic downturn and increasing the price of used LABs in times of increasing demand of LABs and recycled lead. There can be no assurance that global economic conditions will not negatively impact our liquidity, growth prospects and results of operations.
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 U.S. 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 24, 2022. 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 may be at an increased risk of securities class action litigation. Historically, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because early-stage companies have experienced significant stock price volatility in recent years. If we were to be sued, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business. In 2017, a securities class action lawsuit and shareholder derivative lawsuit were filed against us. In 2021, we were able to settle both actions through our issuance of $500,000 of our common shares and our adoption of limited corporate governance reforms, however we incurred significant legal costs in defending both actions and our management was required to devote significant time in managing the defense of the actions.
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, 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 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 us and certain of our former executive officers. On March 23, 2018, the cases were consolidated under the caption In Re: Aqua Metals, Inc. Securities Litigation Case No 3:17-cv-07142. The complaint, as amended, alleged the defendants made false and misleading statements concerning our 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 our November 2016 public offering. In July 2021, the parties entered into a stipulation for settlement of all claims based on the payment of a cash amount to the plaintiffs to be funded by Aqua Metals’ insurance carriers, plus $500,000 to be paid to the plaintiffs by Aqua Metals in cash or common shares, at Aqua Metals’ option.
Beginning on February 2, 2018, five purported shareholder derivative actions were filed in the United States District Court for the District of Delaware against us and certain of our current and former executive officers and directors. 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 alleged that certain of our officers and directors breached their fiduciary duties to us by violating the federal securities laws and exposing us to possible financial liability. In July 2021, the parties entered into a stipulation for settlement of all claims based on our adoption of certain corporate governance reforms. On November 9, 2021, the Court approved the stipulation for settlement and on January 21, 2022 we filed a Current Report on Form 8-K disclosing the corporate reforms we adopted pursuant to the stipulation for settlement.
In October 2021, we filed an action against Johnson Controls Fire Protections, LP (“Defendant”) relating to its involvement in the November 2019 fire at our TRIC facility (Aqua Metals, Inc., et. al v. Johnson Controls Fire Protections, LP, Second Judicial District of the State of Nevada CV21-01891). The Defendant had been retained by Aqua Metals to maintain and service a fire protection system at TRIC. Our complaint alleges that when the fire broke out, the fire protection system for which the Defendant was responsible failed to operate properly, thus leading to fire loss that could have been avoided had the system responded properly. Our complaint alleges Defendant’s liability for a portion of the fire loss based on Defendant’s negligence, breach of contract and other causes of action.
We are not party to any other legal proceedings. We may, from time to time, be party to litigation and subject to claims incident to the ordinary course of business. As our growth continues, we 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 our future financial position, results of operations or cash flows.

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 to recyclers across the globe. Our recycling process is a patented hydrometallurgical technology that is 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. The modular Aqualyzers cleanly generate ultra-pure metal one atom at a time, closing the sustainability loop for the rapidly growing energy storage economy. Our process was originally designed for lead recycling. 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 are also applying our commercialized clean, water-based recycling technology principles to develop the cleanest and most cost-efficient recycling solution for lithium-ion batteries. We believe our process can produce higher quality products at a lower operating cost without the damaging effects of furnaces and greenhouse emissions. Aqua Metals estimates its total addressable market for lithium-ion battery recycling will be approximately $9 billion by 2025.
We were formed as a Delaware corporation on June 20, 2014 for the purpose of engaging in the business of recycling metals through a novel, proprietary and patent-pending process that we developed and named “AquaRefining”. Since our formation, we have focused our efforts initially on the development and testing of our AquaRefining process for lead acid batteries, or LAB, and advanced that process by building a demonstration plant located in the Tahoe Reno Industrial Center in McCarran, Nevada (“TRIC”). We have also developed a business plan which focuses equipment supply services and licensing of the AquaRefining technology to recyclers and began research and development on using the AquaRefining process on lithium-ion batteries at our Innovation Center also located at TRIC.
We completed the development of our first LAB recycling facility at TRIC, in McCarran, Nevada and commenced production of battery breaking and limited operations during the first quarter of 2017. From April 2017 through April 2018, we commenced the shipment of products for sale, consisting of lead compounds as well as plastics and limited production of lead bullion, including AquaRefined lead. During 2018, we commenced the sale of pure AquaRefined lead in the form of two tonne blocks and 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 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 Aqualyzers in operation 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 Company and the insurance carriers agreed on a total claim of $30.25 million which was paid in full by the carriers. Plant clean-up and repair of fire damaged areas began in 2021 and were substantially completed by the end of the year.
Following the November 2019 fire, we have been engaged in the pursuit of our business strategy that is based on the pursuit of licensing opportunities within the lead battery recycling marketplace. We believe our business strategy will require less space and less equipment and focus on the needs of our future licensees. The capital light strategy is based on the pursuit of licensing opportunities within the battery recycling marketplace without maintaining and operating a capital-intensive battery 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.
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. 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. In August 2021, we announced the completion of the V1.5 Aqualyzer. This latest Aqualyzer configuration has now achieved lead production that is over 300% greater than the V1.0 Aqualyzer deployed at the AquaRefinery during commercial production in 2018 and 2019. These results are expected to positively impact capital and operating expenses for the Company’s equipment supply and technology licensing customers. The increase in throughput results in a reduction of more than 60% in the number of Aqualyzers needed for equivalent lead production delivered by the V1.0 model, reducing capital and labor and footprint requirements. This latest iteration has also increased electrical efficiency to 97%, which further improves operating costs.
In February 2021, we announced a strategic investment in LINICO Corporation of up to $2 million to be paid in Aqua Metals shares and cash for a 10% ownership in LINICO as part of our strategy to strengthen growth by potentially applying AquaRefining intellectual property to lithium-ion battery recycling while meeting our lead recycling commercial guidance. In August 2021, we announced that we had established an Innovation Center focused on applying our proven technology to lithium-ion battery recycling research and development and prototype system activities. Our strategic decision to apply our proven clean, closed-loop hydrometallurgical and electro-chemical recycling experience to lithium-ion battery recycling is designed to meet the growing demand for critical metals driven by the global transition to electric vehicles, growth in Internet data centers, and alternative energy applications including solar, wind, and grid-scale storage.
In November 2021, Aqua Metals and LINICO signed a collaboration agreement which sets the parameters for future research and development cooperation, as both companies’ expand into lithium-ion battery recycling and advance our technologies designed to recycle lithium-ion batteries cost-effectively and sustainably. Aqua Metals and LINICO plan to source the necessary lithium-ion feedstock from battery manufacturing scrap and end-of-life cells from various sources, including electric vehicle battery suppliers interested in participating in the eco-network the two companies announced in 2021. LINICO will process the feedstock into high-quality black mass utilizing its proprietary process. The resulting black mass will be used as input feedstock for Aqua Metals’ AquaRefining pilot cells intended to create high purity metals such as nickel, cobalt, and copper as well as other compounds.
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 business strategy that is based on the pursuit of licensing opportunities within the 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. On July 29, 2021, the Company signed a Definitive Agreement with ACME Metal Enterprise Co., Ltd. (ACME) to deploy AquaRefining equipment at its facility in Keelung, Taiwan. We believe the path of licensing our technology has the potential to maximize shareholder value in that it could be far less capital intensive than our operation of one or more recycling facilities and could be funded in part from a combination of cash on hand and asset dispositions.
During the year ended December 31, 2021, we issued 2,995,430 shares of common stock pursuant to an At the Market Issuance Sales Agreement ("ATM") for net proceeds of $10.2 million.
Results of Operations for the Fiscal Year Ended December 31, 2021 Compared to the Fiscal Year Ended December 31, 2020
During the years ended December 31, 2021 and December 31, 2020, revenue resulted from the sale of inventory consisting of lead compounds that were generated during operation of the TRIC facility and prior to the November 2019 fire at our TRIC facility. During the years ended December 31, 2021 and December 31, 2020, 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, 2021 together with the percentage change from the twelve months ended December 31, 2020 for those items (in thousands).

Except for nominal sales of inventory, we did not generate revenue during the years ended December 31, 2021 and December 31, 2020. Plant activity during 2021 consisted of the operation and testing of our improved Aqualyzers.
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 increased approximately 28% for the twelve months ended December 31, 2021, as compared to the twelve months ended December 31, 2020. Cost of product sales increased during 2021 as a result of plant clean-up costs in preparation for the lease and eventual sale of the TRIC facility.
Research and development cost included expenditures related to the improvement of the AquaRefining technology. During the twelve months ended December 31, 2021, research and development costs decreased approximately 9% from the comparable period in 2020. Research and development is a key part of our business strategy and includes our focus on improving the Company's proprietary technology for LAB recycling and advancing our research related to the application of AquaRefining to recycling lithium-ion batteries.
General and administrative expense increased approximately 8% for the twelve months ended December 31, 2021 compared to the twelve months ended December 31, 2020. Increases in general and administrative expenses included changes in stock-based compensation, in addition to an increase in legal expenses and insurance premiums.

Insurance proceeds net of related expenses resulted from collection and payment activity that began in 2020 following the November 2019 fire. The change from period to period is due to the timing of insurance payments and associated fire clean-up expenses. Both of the Company's two PPP loans totaling $332,000 received in May 2020 have been forgiven. One of the PPP loans for $131,000 was forgiven in January 2021 and the second PPP loan for $201,000 was forgiven in May 2021. In conjunction with our year-end accounting, we recognized a non-cash impairment charge for the years ended December 31, 2021 and December 31, 2020 of $0.5 million and $11.7 million, respectively, subsequent to an analysis of our fixed assets and a write down to fair market values. We recognized a loss on the sale of assets held for sale of approximately $1.4 million during the year ended December 31, 2021 as the result of disposals completed in conjunction with the plant clean-up. In addition, we recognized a loss on the sale of assets of $3.5 million recognized in conjunction with the accounting for the lease to purchase arrangement for the Company's McCarran, Nevada facility. The loss on sale of assets held for sale also included $0.7 million resulting from the sale of a battery breaker and related equipment. We recognized interest expense of $21,000 for the year ended December 31, 2021, compared to $1.6 million for the comparable period of 2020. The decrease in interest expense from the prior year is due to the retirement of the Veritex loan during the fourth quarter of 2020 and being debt free since that time. We recognized $379,000 in interest and other income during the year ended December 31, 2021. This compares to interest and other income of $48,000 for the year ended December 31, 2020. The primary driver of the increase in interest and other income was due to the payments received for scrap material salvaged during the plant clean-up process and payments for electricity credits.
Liquidity and Capital Resources
As of December 31, 2021, we had total assets of $33.3 million and working capital of $8.4 million.
The following table summarizes our cash provided by (used in) operating, investing and financing activities (in thousands):

Net cash used in operating activities for the years ended December 31, 2021 and December 31, 2020 was $7.6 million and $11.0 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, 2021, we recognized a $5.7 million loss on disposal of property and equipment. During the year ended December 31, 2021, we recognized $0.5 million expense for impairment on assets held for sale. 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.
Net cash provided by (used in) investing activities
Net cash used in investing activities for the year ended December 31, 2021 was $2.2 million compared to net cash provided by investing activities of $6.6 million for the year ended December 31, 2020. Net cash in investing activities during each of these periods consists primarily of purchases of fixed assets and insurance proceeds received respectively.
Net cash provided by financing activities
Net cash provided by financing activities for the year ended December 31, 2021 consisted of $10.2 million net proceeds from ATM shares sales. Net cash provided by financing activities for the year ended December 31, 2020 consisted of $3.7 million in net proceeds from ATM share sales.
As of December 31, 2021, we had total cash of $8.1 million and working capital of $8.4 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 current business 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 possible sale of equipment, lease revenue, licensing revenue and collection on the sale of the building. 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.
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 have historically sold 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, 2021, management compared the carrying value of the assets held for sale against current fair market values. We determined the carrying value needed to be reduced to align with current fair market values. We recognized a $0.5 million impairment of assets held for sale during 2021. 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 2020. 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.
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 million 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, 2021, the Company has received $30.25 million in insurance payments as a result of the fire damage. The Company does not expect any additional insurance payments related to this matter.
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 currently have three operating leases for real estate. We lease our Reno and McCarran, Nevada and Alameda, California spaces under non-cancelable operating leases. The Reno, Nevada lease expires in 2024 and the Alameda, California lease will expire in May of 2022. 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, in conjunction with our master lease. Subsequent to year end, the lease on Alameda, California facility was terminated. The initial lease term for our mixed office and warehouse space in McCarran, Nevada expired on December 31, 2021. We elected to exercise our first extension option provided for in the McCarran, Nevada lease agreement, which extended the current term of the lease to December 31, 2024.
Finance lease obligation
We currently maintain two finance leases for equipment. In November, we entered into a finance lease for a modular laboratory which expires in October of 2024. Our second finance lease is for warehouse equipment.
Notes payable
We do not have a current notes payable balance. The notes payable balance for year ended December 31, 2020 is related to Payment Protection Program (PPP) loans. See Note 13 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, 2021 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 was 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, 2021 and 2020, the related consolidated statements of operations, stockholders' equity and cash flows, for each of the two years in the period ended December 31, 2021, 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, 2021 and 2020, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2021, 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.
Valuation of Assets Held for Sale - Refer to Note 6 to the Consolidated Financial Statements
Critical Audit Matter Description
As described in Note 6 to the consolidated financial statements, the Company has classified assets as held for sale due to the assets being identified and marketed for sale in their present condition, management committing to their disposal, and the sale of the assets is probable within a year. As of December 31, 2021, these assets have a value of $2.6 million.
Given these factors and assumptions, the related audit effort to evaluate management's valuation of assets held for sale 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 valuation report, selected a sample of assets held for sale and 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 assessed any changes in valuation of assets held for sale since the date of the valuation report by performing the following procedures:
o
Obtained any sales agreements and support for assets sold subsequent to year end.
o
Evaluated other evidence and economic circumstances related to the asset types.
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, 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. 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. In August 2021, we announced the completion of the V1.5 Aqualyzer. This latest Aqualyzer configuration has now achieved lead production that is over 300% greater than the V1.0 Aqualyzer deployed at the AquaRefinery during commercial production in 2018 and 2019. These results are expected to positively impact capital and operating expenses for the Company’s equipment supply and technology licensing customers. The increase in throughput results in a reduction of more than 60% in the number of Aqualyzers needed for equivalent lead production delivered by the V1.0 model, reducing capital and labor and footprint requirements. This latest iteration has also increased electrical efficiency to 97%, which further improves operating costs.
In February 2021, we announced a strategic investment in LINICO Corporation of up to $2 million to be paid in Aqua Metals shares and cash for a 10% ownership in LINICO as part of our strategy to strengthen growth by potentially applying AquaRefining intellectual property to lithium-ion battery recycling while meeting our lead recycling commercial guidance. In August 2021, we announced that we had established an Innovation Center focused on applying our proven technology to lithium-ion battery recycling research and development and prototype system activities. Our strategic decision to apply our proven clean, closed-loop hydrometallurgical and electro-chemical recycling experience to lithium-ion battery recycling is designed to meet the growing demand for critical metals driven by the global transition to electric vehicles, growth in Internet data centers, and alternative energy applications including solar, wind, and grid-scale storage.
In November 2021, Aqua Metals and LINICO signed a collaboration agreement which sets the parameters for future research and development cooperation, as both companies’ expand into lithium-ion battery recycling and advance our technologies designed to recycle lithium-ion batteries cost-effectively and sustainably. Aqua Metals and LINICO plan to source the necessary lithium-ion feedstock from battery manufacturing scrap and end-of-life cells from various sources, including electric vehicle battery suppliers interested in participating in the eco-network the two companies announced in 2021. LINICO will process the feedstock into high-quality black mass utilizing its proprietary process. The resulting black mass will be used as input feedstock for Aqua Metals’ AquaRefining pilot cells intended to create high purity metals such as nickel, cobalt, and copper as well as other compounds.
Our business model focus is on global licensing opportunities to incorporate AquaRefining in the recycling industry.
We have been engaged in the pursuit of our business strategy that is based on the pursuit of licensing opportunities within the 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. On July 29, 2021, the Company signed a Definitive Agreement with ACME Metal Enterprise Co., Ltd. (ACME) to deploy AquaRefining equipment at its facility in Keelung, Taiwan. We believe the path of licensing our technology has the potential to maximize shareholder value in that it could be far less capital intensive than our operation of one or more recycling facilities and could be funded in part from a combination of cash on hand and asset dispositions.
Liquidity and Management Plans
The Company generated revenues of $0.2 million and $0.1 million during the years ended December 31, 2021 and December 31, 2020, respectively.

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, 2021, the Company had a trade accounts receivable balance of $17,000 and has not created a reserve for doubtful accounts. The total accounts receivable balance as of December 31, 2021 and December 31, 2020 consisted of proceeds from the sale of equipment and from the sale or return of inventory.
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.
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, 2021, management compared the carrying value of the assets held for sale against current fair market values. We determined the carrying value needed to be reduced to align with current fair market values. We recognized a $0.5 million impairment of assets held for sale during the period. 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 had decreased due to our focus on a capital light strategy. We recognized a $11.7 million impairment during the period ended December 31, 2020. 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, 2021, the Company determined that the estimated life of the intellectual property properly reflected the current remaining economic life of the asset.
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. As of December 31, 2021, the Company had received a total of $30.25 million in insurance payments as a result of the fire damage. Insurance proceeds of approximately $6.9 million collected during the year ended December 31, 2021, were recorded as other income and netted against related expenses. The Company does not expect any additional insurance payments as a result of the 2019 fire.
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, 2021 or December 31, 2020.
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.

(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
The Company generated revenue of $173,000 for the year ended December 31, 2021, all for the sale of inventory to P. Kay Metals. Revenue for the year ended December 31, 2020 totaled $108,000, for the sale of inventory. Revenue from P. Kay Metals and Clarios (successor of Johnson Controls Battery Group, Inc.) represented 84% and 16%, respectively, of total revenue for the year ended December 31, 2020. The Company's trade accounts receivable balance was $17,000 as of December 31, 2021. The Company did not have a trade receivable balance as of December 31, 2020. The accounts receivable balance on the Company's consolidated balance sheets as of December 31, 2021 and December 31, 2020, consisted of proceeds from the sale of equipment and from the return or sale of inventory.
Recent accounting pronouncements
There were no recent accounting pronouncements or changes in accounting pronouncements during the year ended December 31, 2021 that are of significance or potential significance to the Company.
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 2021. The nominal revenue generated during the years ended December 31, 2021 and 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, 2021 and December 31, 2020.
4.
Lease Receivable
The Company has entered into an Industrial Lease Agreement with LINICO Corporation, a Nevada corporation, or ("LINICO"), dated February 15, 2021 pursuant to which the Company has leased to LINICO the 136,750 square foot recycling facility at TRIC. The lease commenced 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, which was paid on October 15, 2021, and a second nonrefundable deposit of $2.0 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 is 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.
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 was obligated to complete the clean-up of the damaged area, at the Company's expense and repair all damage to the damaged area, at the Company's expense. Repairs and clean up were substantially completed by the end of 2021. With regard to the equipment on-site at TRIC, the Company 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. Subsequent to year end, LINICO purchased approximately $0.8 million of equipment.
The Company accounted for the Industrial Lease and Option to Purchase Agreement as a sales-type lease. As a component of the accounting for the agreement, the Company recognized the estimated fair market value of the land and plant of $17.0 million as a lease receivable, which is reflected on the Company's condensed consolidated balance sheets. The implied interest rate of 0.5% was utilized for the amortization of the scheduled building lease/purchase payments outlined in the agreement. The Company applies the monthly payments received as a reduction to lease receivable and interest income. The interest income recognized from the agreement is included in "Interest and other income" on the Company's condensed consolidated statements of operations. For the year ended December 31, 2021, the Company recognized a reduction in the lease receivable balance of approximately $553,000 and recorded $59,000 of interest income related to this agreement.

On November 29, 2019, there was a fire in the AquaRefining area of the plant. As a result of the fire, during the year ended December 31, 2020, the Company wrote off approximately $22.4 million of fixed assets that were damaged. These assets consisted of operational equipment, building and equipment under construction. The disposal of the fire damaged fixed assets included a decrease of accumulated depreciation of $2.5 million. The net write-off of fixed assets totaled $19.9 million. Further, during the year ended December 31, 2020, the Company conducted a review of its fixed assets for impairment and as a result, recognized an impairment expense of $11.7 million with respect to the write-down of equipment to fair values. 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.

Investments
On February 15, 2021, the Company entered into a Series A Preferred Stock Purchase Agreement with LINICO Corporation, that provided for the Company's issuance of 375,000 shares (“Aqua Shares”) of the Company's common stock in consideration of LINICO’s issuance of 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. Subsequent to year end the Company exercised the warrant for all 500 LINICO Series A Preferred shares. The 2,000 shares of the Series A Preferred Stock represents approximately 12% of LINICO common stock on a fully diluted basis.
The Company accounted for the LINICO investment under ASC 321, Investments-Equity Securities, using the measurement alternative of recording at cost as the investment in LINICO doesn’t have a readily determinable fair value.
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.
As LINICO’s sale of the 375,000 of Aqua Shares resulted in net proceeds to LINICO that were less than $1,500,000, the Company was required to pay LINICO the difference of $232,000 in cash.
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 88% 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.

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”). The 2019 Plan was most recently amended and restated effective as of the Company’s 2020 Annual Stockholders’ Meeting. 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, 2021 and December 31, 2020. The net valuation allowance increased by approximately $3.8 million during the year ended December 31, 2021. The increase in net valuation allowance primarily relates to net operating losses generated during 2021.
The Company has Federal and California net operating loss carryforwards of approximately $135.6 million and $4.1 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, 2021, the Company had research and development credits carryforward of approximately $0.4 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, 2021, 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, 2021, the Company’s total amount of unrecognized tax benefit was approximately $0.5 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.
18.
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. Beginning in January 2021, the Plan included employer matching contributions.
19.
Subsequent Events
The Company has evaluated subsequent events through the date which the consolidated financial statements were available to be issued.
The Company held a 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. Subsequent to year end, the Company exercised the warrant for all 500 LINICO Series A Preferred shares. Following the exercise, the Company held a total of 2,000 shares of the Series A Preferred Stock representing approximately 12% of LINICO common stock on a fully diluted basis.
Subsequent to the year end, the Alameda lease was terminated.

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, 2021 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, 2021 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 13a-15(f) under the Exchange Act. Our management has assessed the effectiveness of our internal controls over financial reporting as of December 31, 2021 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, 2021, and based on that evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2021.
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.
