Business

Background

PART I

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 $ 9   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

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,

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.

Properties

Our executive offices are presently located in 4,183 square feet of class A office space in Reno, Nevada. We lease this facility at a lease rate of approximately

$11,000 per month. The lease term began in September, 2021 and expires September 30, 2024.

Our  executive  offices  were  previously  located  in  21,697  square  feet  of  office  and  industrial  space  in  a  multi-building  commercial  project  known  as  “Marina
Village” located in Alameda, California. The lease term is 76 months, commencing February 1, 2016, and expiring May 31, 2022. We sublet the property with the sublease
commencing on February 4, 2019 and expiring May 31, 2022. Subsequent to year end, the lease on this building was terminated.

We have developed and lease an Innovation Center focused on applying Aqua Metals technology to lithium-ion battery recycling. We lease this facility at a lease
rate of approximately $11,000 per month. The original lease term expired on December 31, 2021 but was renewed for a three year period which commenced on January 1,
2022 and expire on December 31, 2024.

We have developed and own a 136,750 square foot LAB recycling facility on 11.73 acres of land located in TRIC, a 107,000-acre park located nine miles east of
Reno, Nevada on I-80. We have entered into an Industrial Lease Agreement with LINICO Corporation, or LiNiCo, dated February 15, 2021, pursuant to which we have
leased the TRIC facility to LiNiCo. The lease commences April 1, 2021 and expires on March 31, 2023. During the lease term, LiNiCo has the option to purchase the land
and facilities at a purchase price of $14.25 million if the option is exercised and the sale is completed by October 1, 2022, and $15.25 million if the option is exercised and
the sale is completed after October 1, 2022, and prior to March 31, 2023. The purchase option is subject to LiNiCo’s payment of a nonrefundable deposit of $1.25 million by
October 15, 2021, and a second nonrefundable deposit of $2 million by November 22, 2022, both of which will be applied towards the purchase price. LiNiCo made the first
deposit of $1.25 million in early October 2021. 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.  The  lease  agreement  allows  us  to  retain  the  use  of  a  portion  of  the  facility  for  our  ongoing  research  and  development  activities,  including
operation of the lab and the use of office space.

With  respect  to  the  portion  of  the  facility  that  was  damaged  in  the  November  2019  fire,  consisting  of  approximately  30,000  square  feet,  we  our  obligated  to
complete  the  clean-up  of  the  damaged  area,  at  our  expense. As  of  the  date  of  this  report  all  clean  up  and  repair  on  the  building  was  substantially  completed.  The  lease
agreement contains customary representations, warranties, and indemnities on the part of both parties.

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.

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.

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.

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

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
o
o

Evaluated the reasonableness of the assumptions, data, methodology and models used in the valuation report.
Performed corroborative calculations for the various analyses, confirming that the methodologies, inputs and calculations appeared accurate.
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.

1. Organization and Operations

AQUA METALS, INC.
Notes to Consolidated Financial Statements 

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. 

I n 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. The Company had net
losses of $18.2 million and $25.8  million  for  the  years  ended December  31,  2021 and December 31, 2020,  respectively. As  of December  31,  2021,  the  Company’s  cash
balance was $8.1 million. As of the date of this report, the Company believes it may require additional capital, in order to fund its current level of ongoing costs over the
next twelve months and move forward with its licensing strategy.

Summary of Significant Accounting Policies

Basis of presentation and consolidation

The accompanying consolidated financial statements include those of Aqua Metals, Inc. and its subsidiaries, after elimination of all intercompany accounts and transactions.
The Company has prepared the accompanying consolidated financial statements in accordance with accounting principles generally accepted in the United States of America
(“GAAP”) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”).

Table of Contents

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.

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.

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.

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.

Assets Held for Sale

Assets  are  classified  as  held  for  sale  when,  among  other  factors,  they  are  identified  and  marketed  for  sale  in  their  present  condition,  management  is  committed  to  their
disposal, and the sale of the asset is probable within one year. Management believes these assets are no longer necessary for the Company's future operating plans. As of  
December 31, 2021, Aqua Metals had assets with a book value of $2.6 million classified as assets held for sale. 

At December 31, 2021, the Company 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.

Property and equipment depreciation expense was $0.6 million and $1.9 million for the years ended December  31,  2021 and December 31, 2020, respectively. Equipment
under construction is comprised of various components being manufactured or installed by the Company.

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.

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.

Notes Payable

On May 7, 2020, the Company received loan proceeds in the amount of approximately $332,000 under the Paycheck Protection Program (“PPP”). The PPP, established as
part of the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), provided for loans to qualifying businesses. The loans and accrued interest are forgivable if
the borrower uses the loan proceeds for eligible purposes, including payroll, benefits, rent and utilities, and maintains its payroll levels. The Company used the loan proceeds
for  purposes  consistent  with  the  PPP  requirements  and  applied  for  loan  forgiveness.  During  the  year  ended   December  31,  2021,  both  of  the  Company's two  PPP  loans
totaling $332,000 were forgiven.

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. Option awards are exercisable until their expiration, which may not exceed 10 years from the grant date.

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.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

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.
