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.” In 2015, Aqua Metals developed a breakthrough metal recycling technology that utilizes a clean, closed-
loop process that can produce high-purity metal. We believe this innovative approach can deliver raw materials back into the manufacturing supply chain, while reducing
emissions and toxic byproducts and creating a safer work environment. In particular, the modular AquaRefining systems have already demonstrated the ability to recover
critical minerals from both lead acid batteries and lithium-ion batteries and can reduce the cost and environmental impact of battery recycling.

In 2017, Aqua Metals initially applied this breakthrough technology in the lead acid battery (LAB) recycling industry, building its first integrated recycling system
for breaking LAB and recovering pure metal from the resulting scrap. In 2018, we commenced sale of finished products of AquaRefined lead to market in the form of either
two tonne blocks or lead ingots for battery manufacturing. In 2019, we operated our demonstration AquaRefinery at commercial quantity production levels and produced
over 35,000 AquaRefined ingots through twenty-four hours a day, seven days a week for sustained periods of time.

On  November  29,  2019,  a  fire  occurred  in  the AquaRefining  area  of  the  lead  recycling  facility  at  Tahoe-Reno  Industrial  Center  (TRIC).  The  fire  was  caused  by
contracting activities happening on site, and not related to the technology or process of AquaRefining. 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 completed in 2022. 

During 2020, we engaged in the pursuit of our business strategy that is based on finding licensing opportunities within the lead battery recycling marketplace. During
2020  and  2021,  we  successfully  iterated  our  lead AquaRefining  ‘Aqualyzer’  through  a  1.25  and  a  1.5  version  which  tripled  the  throughput  of  the  2019  iteration  that
produced over 35,000 industry standard ingots in commercial production.  During the third and fourth quarters of 2022, we deployed and operated the first phase of lead
AquaRefining with our partner ACME Metal in Taiwan. The operation continues to successfully produced lead. The two installed Aqualyers are producing at demonstration
levels.

In  February  2021,  we  announced  our  entry  into  the  lithium-ion  battery  (LiB)  recycling  market  through  a  key  provisional  patent  we  filed  that  applies  the  same
innovative AquaRefining approach. In August 2021, we announced we had established our Innovation Center in TRIC focused on applying our proven technology to LiB
recycling  research  and  development  and  prototyping.  Our  strategic  decision  to  apply  our  proven  clean,  closed-loop  hydrometallurgical  and  electrochemical  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. 

During the first half of 2022, we announced our ability to recover copper, lithium hydroxide, nickel, and cobalt from lithium-ion battery black mass at the Company’s
Innovation Center. During 2022, we built our fully-integrated pilot system, located within the Company’s Innovation Center, which is designed to allow Aqua Metals to be
the first company in North America to recycle battery minerals from black mass, sell them in the U.S. and position the Company as the first LiB recycler in North America to
align with the U.S. government’s goal of retaining strategic battery minerals within the domestic supply chain.

During 2022, we conducted environmental comparisons based on Argonne National Lab’s modeling of lithium battery supply chains – called EverBatt. The initial
results  indicate  that  AquaRefining  is  a  cleaner  approach  to  LiB  recycling,  producing  far  less  CO2  waste  streams  than  smelting  or  chemical  driven
hydrometallurgical  processes  currently  on  the  market.  In  December  2022,  we  completed  equipment  installation  and  began  to  operate  our  first-of-a-kind  LiB  recycling
facility, utilizing electricity to recycle instead of intensive chemical processes, fossil fuels, or high-temperature furnaces. In January of 2023, Aqua Metals recovered its first
metals from recycling lithium batteries using the patent-pending Li AquaRefining process, and is currently scaling operations at the Company’s pilot facility.

In February 2023, we acquired a five-acre recycling campus at TRIC. The facility is designed, when fully developed, to process up to 10,000 tonnes of lithium-ion
battery material each year using our proprietary AquaRefining technology. We expect to complete development of phase one, including all equipment installation, by the end
of  2023  and  to  commence  operations  at  the  new  campus  in  the  first  quarter  of  2024.  We  have  financed  the  purchase  of  the  property  with  a  $3  million  loan  from  an
unaffiliated mortgage lender. The loan accrues interest at a fixed annual rate of 9.50%. Interest-only payments are due monthly for the first twenty-four months and the
principal and all unpaid interest is due on March 1, 2025.  We have the right to prepay the loan at any time, provided that we must pay guaranteed minimum interest of
$213,750 (9-months of interest). The loan agreement includes representations, warranties, and affirmative and negative covenants that are customary of institutional loan
agreements. The loan is collateralized by a first priority lien on the building and site improvements.

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 metal recycling with its patented and patent-pending AquaRefining™ technologies. 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
and  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 low-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
metals. AquaRefining is designed to deliver raw materials back into the manufacturing supply chain, and replaces the need for polluting furnaces and hazardous chemicals
with electricity-powered electroplating to recover valuable metals and materials from spent batteries with higher purity, lower emissions, and minimal waste.

Aqua  Metals  has  demonstrated  this  technology  in  lead  acid  battery  recycling  and  is  currently  scaling  operations  for  its  lithium-ion  battery  recycling  pilot  facility.
AquaRefining  for  lead  uses  a  bio-degradable  aqueous  solvent  and  a  novel  ambient  temperature  electro-chemical  process  to  produce  lead  suitable  for  use  in  new
battery 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 purer
than lead made from mining processes.

We are in the process of demonstrating that Li AquaRefining (which is also electricity-based and fundamentally non-polluting) can create the highest quality and
highest  yields  of  recovered  minerals  from  lithium-ion  batteries,  with  lower  waste  streams  and  lower  costs  than  alternatives.  With  the  proven  ability  to  recover  valuable
metals  from  lithium-ion  batteries  at  our  pilot  facility  in  TRIC,  our  goal  is  to  process  commercial  quantities  of  high-purity  lithium  hydroxide,  nickel,  cobalt,  manganese
dioxide,  and  copper  in  pure  forms  that  can  be  sold  to  the  general  metals  and  superalloy  markets,  and  can  be  made  into  battery  precursor  compound  materials  with
proven processes that are already used in the battery industry.

The  Company  is  also  exploring  additional  novel  applications  of AquaRefining  across  metals  recycling  industries  at  our  Innovation  Center,  including  recycling

emerging battery chemistries and opportunities to develop additional products for sale to customer specifications.

Our Markets

Aqua  Metals’ AquaRefining  process  produces  high  purity  metals  and  alloys  that  can  be  returned  into  the  battery  manufacturing  supply  chain  or  sold  into  metals
markets for use across industries. This combination of approaches and the broad applicability of the end products we aim to produce enables Aqua Metals to create low-
emissions inputs for the battery supply chain or to help decarbonize other sectors that utilize these critical metals and superalloys – creating a more resilient and adaptable
business model for the Company as a whole.

Metals Markets

Most of the minerals and metals that can be recovered in the recycling of batteries of various chemistries are also globally traded commodities. Lead, copper, cobalt,
nickel, and other metals can be recovered and sold in pure metal form into these markets at the prevailing price or sold directly to a customer at a price set relative to the
current market price.

For example, battery metals are globally traded metal commodities. Metals such as lead for LABs and nickel, cobalt, copper and lithium for LIBs are the essential
components  for  the  world’s  rechargeable  batteries.  These  metals  are  globally  traded  primarily  on  the  London  Metals  Exchange  (LME),  although  the  smaller  Shanghai
Metals Exchange (SHME) in China also trades these elements. 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.  In  their  pure  forms,  the  other  minerals  that Aqua  Metals  intends  to  recover  from  spent  batteries  can  be  sold  into  these  global  markets.
Unlike lead markets, recycling currently makes up a smaller portion of metals like cobalt and nickel, relying almost entirely on newly mined ore and refining to meet global
demand.

As noted above, although metals are traded as a commodity on the various global exchanges, 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 metals, in metal form. Based on market and product knowledge with buyers of metals in the U.S. and global metals markets, different grades (termed
alloys) of metal are traded at a premium to the base LME price. Metal alloys, which are typically designed specifically for the customer, are also sold at a premium above the
base LME, whereas byproducts (generally lower purity, compounds, or scrap) are traded at a discount to the LME as they are based on the underlying metals content and its
form.

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 environmental issues 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, potentially with
more waste than product recovered, 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 proprietary, non-toxic solvents that dissolves metal compounds. The second is a proprietary electro-chemical process
and our modular Aqualyzer cells that selectively target each critical element and converts the dissolved metal compounds into high purity metals and/or salts.

The AquaRefining process begins with the processing of crushed used batteries either in the form of paste (for LAB) or, 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.

We  have  demonstrated  at  bench  scale  and  begun  to  demonstrate  in  our  pilot  facility  that  our  lithium  battery AquaRefining  process  can  generate  cobalt,  lithium
hydroxide, copper, nickel, and manganese dioxide from lithium-ion battery black mass. A significant benefit of our AquaRefining process is that it can produce higher yields
of higher purity thus higher value product than that derived from primary smelters with product from secondary sources.

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 varying
capacities to meet the specific needs of potential customers and suppliers. We have also developed an integrated software and portal called PureMetrics that keeps track of
production and key operating metrics.

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 continue to 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

Aqua  Metals  is  engaged  in  the  business  of  applying  its  commercialized  clean,  water-based  recycling  technology  principles  to  develop  the  clean  and  cost-efficient
recycling solutions for both lead and lithium-ion (“Li”) batteries. Our recycling process is a patented hydro- and electrometallurgical technology that is a novel, proprietary
and  patented  process  we  developed  and  named AquaRefining. AquaRefining  is  a  low-emissions,  closed-loop  recycling  technology  that  replaces  polluting  furnaces  and
hazardous  chemicals  with  electricity-powered  electroplating  to  recover  valuable  metals  and  materials  from  spent  batteries  with  higher  purity,  lower  emissions,  and  with
minimal waste. The “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 offer technology licensing and related
services to lead recyclers across the globe for lead recycling.

We  are  also  applying  our  commercialized  clean,  water-based  recycling  technology  principles  with  the  goal  of  developing  the  cleanest  and  most  cost-efficient
recycling  solution  for  lithium-ion  batteries.  We  believe  our  process  has  the  potential  to  produce  higher  quality  products  at  a  lower  operating  cost  without  the  damaging
effects of furnaces and greenhouse emissions. Aqua Metals estimates the total addressable market for lithium-ion battery recycling will be approximately $9 billion by 2025
and grow to exceed lead battery recycling by the end of the decade. Unlike the mature lead recycling market, the deployed lithium-ion battery recycling infrastructure to
serve market growth does not exist today.

Our business strategy is based on the pursuit of building and operating Li AquaRefining recycling capacity to meet the growing demand for critical metals in lithium-
ion  batteries  driven  by  innovations  in  automobile  batteries,  growth  in  internet  data  centers,  and  alternative  energy  applications,  including  solar,  wind,  and  grid-scale
storage. We are also continuing to pursue equipment supply and licensing opportunities within the lead acid battery recycling marketplace.

We are in the process of demonstrating that Li AquaRefining, which is fundamentally non-polluting, can create the highest quality and highest yields of recovered
minerals from lithium-ion batteries with lower waste streams and lower costs than existing alternatives. We have already demonstrated at our pilot facility our ability to
recover key valuable minerals in lithium-ion batteries, such as lithium hydroxide, copper, nickel, cobalt, and other compounds in 2022. Our goal is to process commercial
quantities of nickel, cobalt, and copper in a pure metal form that can be sold to the general metals and superalloy markets and can be made into battery precursor compound
materials with known processes already used in the mining industry. We have installed, commissioned, and began to operate the first Li AquaRefining pilot plant at the end
of  2022,  scaling  towards  a  commercial  demonstration  operation  through  2023.  The  location  for  the  pilot  demonstration  quantity  is  currently  the  Innovation  Center  with
expansion to happen at our new 5-acre recycling campus to commercial quantities to ~10,000 tonnes / year or more of production starting in 2024, which would be enough
material to build ~100,000 average EVs or ~400,000 average home energy storage systems.  At today’s metals prices, this capacity could also generate $200,000,000 plus
of revenues for the company.

Our focus for the lead market is providing equipment and licensing of our lead acid battery recycling technologies in an enabler model which allows us to work with
anyone in the industry globally and address the entire marketplace.  Our focus for the lithium market includes operating our first-of-a-kind lithium battery recycling facility,
utilizing  electricity  to  recycle  instead  of  intensive  chemical  processes,  fossil  fuels,  or  high-temperature  furnaces.  We  are  also  exploring  partnership  and/or  joint
venture agreements, particularly as our Li AquaRefining matures through 2023 and into 2024. We believe that Aqua Metals is in a position to become one of the few critical
minerals recovery players for which our environmental and economic value proposition should generate both great commercial wins and potentially government grants to
accelerate our credibility and progress. 

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.

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, retrofits, and new
construction.  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.

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 with low yields 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  electrometallurgical  processes  like  the  process  we  have  commercialized  for  lead,  we  call  it  “Li
AquaRefining.” We believe, and our lab scale and then bench scale and now pilot scale 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.

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  9  US  patents,  91  international  patents,  and  2  allowances  (international).  In  addition  to  the  US  patents,  we  have  international
patents/allowances  in  the African  Regional  Intellectual  Property  Organization, African  Intellectual  Property  Organization, Australia,  Brazil,  Canada,  Chile,  China,  the
Eurasian Patent Organization, European Union, Honduras, India, Indonesia, Japan, Malaysia, Mexico, Peru, South Korea, South Africa, Turkey, Ukraine, and Vietnam. We
also  have  50  US  and  foreign  patent  applications  pending  with  patent  applications  pending  in  21  additional  non-US  jurisdictions  across  ten  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.

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 a limited operating history and limited revenue producing operations and are currently undertaking a reset of our business strategy.  Therefore, it is
difficult for potential investors to evaluate our business. We formed our corporation in June 2014. From inception through December 31, 2022, 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, and all but approximately $285,000 of which was derived prior to the November 2019 fire at our former LAB recycling facility at TRIC. Following the TRIC fire, we
chose to suspend 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.  We also commenced the research and development of the application of
our AquaRefining technology to the recycling of lithium-ion batteries. Based upon our success to date in recovering high value metals from lithium-ion batteries using our
AquaRefining technology, we have commenced the development of a five-acre recycling campus designed to process up to 10,000 tonnes of lithium-ion battery material
annually. While we intend to continue to pursue our licensing business model, the development of our lithium-ion battery recycling facility represents a significant change in
our business strategy and course of operations.  As of the date of this report, we have estimated that we will begin to realize revenues from lithium-ion battery recycling
within  the  coming  year,  however  we  are  unable  to  estimate  when  we  expect  to  commence  any  meaningful  commercial  or  revenue  producing  operations  from  either  our
licensing model or our lithium-ion battery recycling facility. Our limited operating history makes it difficult for potential investors to evaluate our technology or prospective
operations and we are, for all practical purposes, an early-stage company subject to all the risks inherent in the initial organization, financing, expenditures, complications
and delays in a new business, including, without limitation:

•

•

•
•

•

our ability to successfully apply, and realize the expected benefits of applying, our AquaRefining technology to the plating of high value metals found in lithium-ion
batteries, including cobalt, nickel, and copper;
the timing and success of our plan of commercialization and the fact that we have not entered into a commercial license for our AquaRefining technology and only
have recently commenced the development of our lithium-ion recycling facility;
our ability to successfully develop our proposed lithium-ion recycling facility;
our ability to demonstrate that our AquaRefining technology can recycle either LABs or lithium-ion batteries on a commercial scale; and
our ability to license our AquaRefining process and sell our AquaRefining equipment to ACME Metal Enterprise Co., Ltd and other recyclers of LABs and lithium-
ion batteries.

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.

We recently commenced the development of a lithium-ion recycling facility, however we are in the early stages of developing the facility and there can be no
assurance that we will be able to successfully develop the facility or, if we do, realize the expected benefits of the facility . In January 2023, we announced our plans to
conduct the phased development of a five-acre recycling campus in the Tahoe-Reno Industrial Center, or TRIC, in McCarran, Nevada. The facility is designed, when fully
developed, to process up to 10,000 tonnes of lithium-ion battery material each year using our proprietary AquaRefining technology.  As of the date of this report, we entered
into an agreement to acquire the five-acre site, plus the existing 21,000 square foot building, and have obtained a non-binding letter of intent with a mortgage lender that we
have worked with in the past to acquire the necessary financing for the property purchase. Subsequent to year end, we closed on the acquisition financing and the property
was purchased on February 1, 2023. However, we have no agreements, understandings or arrangements at this time for our acquisition of the financing required to build out
phase one and there can be no assurance will be able to acquire such financing in a timely manner, or at all.  Subject to our receipt of development financing on a timely
basis, we expect to complete development of phase one, including all equipment installation, by the end of 2023 and to commence operations at the new campus in the first
quarter of 2024. However, there can be no assurance we will be able to do so.

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. In the fourth quarter of 2022, we
successfully recovered copper from spent lithium-ion batteries at production scale using our AquaRefining technology and we are currently applying our technology to the
recovery of the other high value metals in lithium-ion batteries, including lithium hydroxide, nickel, cobalt, and manganese dioxide. However, we have only recently begun
our efforts to recover lithium hydroxide, nickel, cobalt, and manganese dioxide from recycled 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,  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. 

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 battery 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 from LABs and high value metals from lithium-ion batteries on a
small scale, we have not processed either LABs or lithium-ion batteries on a commercial scale. We recently commenced the development of a five-acre recycling campus
designed to process lithium-ion batteries, however there can be no assurance that we will be able to complete the development of the recycling facility or, if we are able to do
so, that we will be able to successfully process lithium-ion batteries on a commercial scale. In this regard, as we developed our LAB recycling facility at TRIC during 2018
and 2019, there can be no assurance that we will not encounter unforeseen complications as we pursue our revised business model.

We will 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, 2022, we had total cash of $7.1 million and working capital of $10.9 million. As of the date of this report, we believe that we may require additional
capital in order to fund our current level of ongoing costs and our proposed business plan over the next 12 months as we move forward with our business 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. 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  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 from LABs and high value
metals  from  lithium-ion  batteries  through  a  novel,  and  proven  on  a  modest  scale,  technology.  While  the  production  of  recycled  LABs  and  lithium-ion  batteries  is  an
established business, to date virtually all recycled lead and high value metals have 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 or lithium-ion batteries without smelting. Further, there can be no assurance that either we 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 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 the potential customers. A key component of our business plan is the production of recycled
metals through our AquaRefining process. Our customers will require that our AquaRefined metals meet certain minimum purity standards and, in all likelihood, require
independent assays to confirm the metal’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 metals in significant commercial quantities and there can be no assurance that we will be able to do so or, that such metals will meet the
required purity standards of our customers.  Further, while we have recently commenced the application of our AquaRefining process towards the recovery of high value
metals  found  in  lithium-ion  batteries,  such  as  cobalt,  nickel,  lithium  hydroxide,  copper,  and  manganese  dioxide,  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  only  recently  commenced  commercial  operations  in  the  area  of  recycling  of  lithium-ion  batteries.  There  can  be  no
assurance  that  either  us  or  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 9 US patents, 91 international patents

and 2 allowances (international) related to our AquaRefining process.

We  also  have  further  patent  applications  pending  in  the  United  States  and  numerous  corresponding  patent  applications  pending  in  21  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.

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 battery metal is relatively volatile and reacts to general global economic conditions.  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 LIBs and decreasing the price of lead in times of
economic downturn and increasing the price of used batteries 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 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 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.

Table of Contents

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, 2022, the reported high and low sales prices of our
common stock have ranged from $1.59 to $0.50 through February 17, 2023. 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  was  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. This lease was terminated in early 2022.

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 commenced April 1, 2021 and expires on March 31, 2023. LiNiCo has agreed to a purchase price of $15.25 million and paid a
nonrefundable  deposit  of  $1.25  million  in  October  2021,  and  a  second  nonrefundable  deposit  of  $2  million  in  October  2022,  per  the  terms  of  the  agreement.  Both
nonrefundable deposits in the total of $3.25 million will be applied towards the sale price.

In February 2023, we purchased a property located in TRIC. The property includes both the land and an existing building. The land totals approximately five acres
and  the  building  is  approximately  21,000  square  feet.  The  Company  intends  to  redevelop  the  existing  building  and  install  our  first  commercial-scale  Li AquaRefining
system, with an estimated capacity of 3,000 tonnes of materials processed each year. The Company is also exploring plans to develop the remaining land on the property to
expand capacity and operations.

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. We are not party to any legal proceedings that, if determined adversely to us, would
individually or taken together have a material adverse effect on our business, results of operations, financial condition or cash flows.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

Aqua  Metals  is  engaged  in  the  business  of  applying  its  commercialized  clean,  water-based  recycling  technology  principles  to  develop  the  clean  and  cost-efficient
recycling solutions for both lead and lithium-ion (“Li”) batteries. Our recycling process is a patented hydro- and electrometallurgical technology that is a novel, proprietary
and  patented  process  we  developed  and  named AquaRefining. AquaRefining  is  a  low-emissions,  closed-loop  recycling  technology  that  replaces  polluting  furnaces  and
hazardous  chemicals  with  electricity-powered  electroplating  to  recover  valuable  metals  and  materials  from  spent  batteries  with  higher  purity,  lower  emissions,  and  with
minimal  waste.  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 are also
applying  our  commercialized  clean,  water-based  recycling  technology  principles  with  the  goal  of  developing  the  cleanest  and  most  cost-efficient  recycling  solution  for
lithium-ion batteries. We believe our process has the potential to produce higher quality products at a lower operating cost without the damaging effects of furnaces and
greenhouse emissions. Aqua Metals estimates the total addressable market for lithium-ion battery recycling will be approximately $9 billion by 2025 and grow to exceed
lead battery recycling by the end of the decade. 

In  February  2021,  we  announced  our  entry  into  the  lithium-ion  battery  (LiB)  recycling  market  through  a  key  provisional  patent  we  filed  that  applies  the  same
innovative AquaRefining approach. In August 2021, we announced we had established our Innovation Center in TRIC focused on applying our proven technology to LiB
recycling  research  and  development  and  prototyping.  Our  strategic  decision  to  apply  our  proven  clean,  closed-loop  hydrometallurgical  and  electrochemical  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. 

During the first half of 2022, we announced our ability to recover copper, lithium hydroxide, nickel and cobalt from lithium-ion battery black mass at the Company’s
Innovation Center. During 2022, we built our fully-integrated pilot system, located within the company’s Innovation Center, which is designed to allow Aqua Metals to be
the  first  company  in  North America  to  recycle  battery  minerals  from  black  mass  and  sell  them  in  the  U.S.  and  position  the  Company  as  the  first  LiB  recycler  in  North
America to align with the U.S. government’s goal of retaining strategic battery minerals within the domestic supply chain.

During 2022, we conducted environmental comparisons based on Argonne National Lab’s modeling of lithium battery supply chains – called EverBatt. The initial
results indicate that AquaRefining is a cleaner approach to LiB recycling, producing far less CO2 waste streams than the two evaluated primary processes currently on the
market which include smelting and chemically driven hydrometallurgical process. In December of 2022, we completed equipment installation and began to operate our first-
of-a-kind LiB recycling facility, utilizing electricity to recycle instead of intensive chemical processes, fossil fuels, or high-temperature furnaces. In January of 2023, Aqua
Metals recovered its first metals from recycling lithium batteries using the patent-pending Li AquaRefining process and is currently scaling operations at the Company’s
pilot facility.

In February 2023, we acquired a five-acre recycling campus at TRIC. The facility is designed, when fully developed, to process up to 10,000 tonnes of lithium-ion
battery material each year using our proprietary AquaRefining technology. We expect to complete development of phase one, including all equipment installation, by the end
of 2023 and to commence operations at the new campus in the first quarter of 2024. Our initial plans call for upgrading the current building to install a commercial-scale Li
AquaRefining system capable of recycling 3,000 tons of lithium battery ‘black mass’ each year. We expect to complete redevelopment of the current space and finalize
equipment  installation  this  year,  and  to  commence  operations  at  the  new  campus  in  the  first  quarter  of  2024.  The  purchase  of  the  new  property  was  funded  with  a  non-
dilutive  loan.  We  also  intend  to  finance  the  development  of  Phase  One  through  a  non-dilutive  loan.  The  Company  is  currently  in  discussions  with  a  provider  of  debt
financing that has provided financing in the past.

Our focus for the lead market is providing equipment and licensing of our lead acid battery recycling technologies in an enabler model which allows us to work with
anyone in the industry globally and address the entire marketplace.  Our focus for the lithium market includes operating our first-of-a-kind lithium battery recycling facility,
utilizing  electricity  to  recycle  instead  of  intensive  chemical  processes,  fossil  fuels,  or  high-temperature  furnaces.  We  are  also  exploring  partnership  and/or  joint  ventures
agreements,  particularly  as  our  Li AquaRefining  matures  through  2023  and  into  2024.    We  believe  that Aqua  Metals  is  in  a  position  to  become  one  of  the  few  critical
minerals recovery players for which our environmental and economic value proposition should generate both great commercial wins and potentially government grants to
accelerate our credibility and progress.

During the year ended December 31, 2022, we issued 6,742,069 shares of common stock pursuant to an At the Market Issuance Sales Agreement ("ATM") for net

proceeds of $6.5 million.

Results of Operations for the Fiscal Year Ended December 31, 2022 Compared to the Fiscal Year Ended December 31, 2021

During the years ended December 31, 2022 and December 31, 2021, revenue resulted from the sale of inventory consisting of lead compounds that were generated
during operation of the TRIC facility prior to the November 2019 fire at our TRIC facility. During the years ended December 31, 2022 and December 31, 2021, 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,  2022  and  2021  together  with  the  percentage  change  from  the  twelve  months
ended December 31, 2021 for those items (in thousands).

Except  for  nominal  sales  of  inventory,  we  did  not  generate  revenue  during  the  years  ended  December  31,  2022  and  December  31,  2021.  Plant  activity  during

2022 consisted of testing our lithium-ion battery recycling technology and developing the prototype system activities.   

Plant operations and clean-up includes supplies and related costs, salaries and benefits, consulting and outside services costs, depreciation and amortization costs,
insurance,  travel  and  overhead  costs.  Plant  operations  and  clean  up  decreased  approximately  44%  for  the  twelve  months  ended  December  31,  2022,  as  compared  to  the
twelve months ended December 31, 2021 as a result of plant clean-up and repair of fire damaged areas that began in 2021 and were completed earlier in 2022.

Research and development cost included expenditures related to the improvement of our lithium-ion battery recycling technology. During the twelve months ended
December  31,  2022,  research  and  development  costs  increased  approximately  94%  from  the  comparable  period  in  2021.  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 1% for the twelve months ended December 31, 2022 compared to the twelve months ended December

31, 2021. Increases in general and administrative expenses included changes in payroll and payroll related expenses, in addition to an increase in travel expenses.

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. The Company does not expect any additional insurance payments related
to this matter. Both of the Company's two PPP loans totaling $332,000 received in May 2020 have been forgiven.

For  the  year  ended  December  31,  2022,  we  recognized  a  write  down  to  fair  market  value  of  our  assets  held  for  sale  of  approximately  $0.6  million.
We recorded a gain of $0.7 million that resulted from the write-off of plant commitment accrued expenses and $0.1 million gain that resulted from the sale of construction in
progress ("CIP") equipment. The gain was offset by a loss on the sale of assets held for sale of approximately $0.1 million and $0.1 million bad debt resulting from the sale
of the battery breaker. For the year ended December 31, 2021, we recognized a non-cash impairment charge of $0.5 million, 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  of  $3.5  million  related  to  the  purchase  arrangement  for  the
Company's facility located at 2500 Peru. 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 $125,000 for the year ended December 31, 2022 and $21,000 for the comparable period of 2021. The increase in interest expense
from the prior year is due to the interest paid on the secured loan agreement we entered in September 2022. We recognized $262,000 in interest and other income during the
year  ended  December  31,  2022  and  $379,000  for  the  year  ended  December  31,  2021.  The  primary  driver  of  the  decrease  in  interest  and  other  income  was  due  to
the payments received for scrap material salvaged during the 2021 plant clean-up process.

Net  cash  used  in  operating  activities  for  the  years  ended  December  31,  2022  and  December  31,  2021  was  approximately  $10.1  million  and  $7.6  million,
respectively.  Net  cash  used  in  operating  activities  during  each  of  these  periods  consisted  primarily  of  our  net  loss  adjusted  for  non-cash  items  such  as
depreciation,  amortization,  and  stock-based  compensation  charges  as  well  as  net  changes  in  working  capital.  During  the  year  ended  December  31,  2022,  we  recognized
a $0.6 million gain on disposal of property and equipment and approximately $0.6 million expense for impairment on assets held for sale. During the year ended December
31, 2021, we recognized a $5.7 million loss on disposal of property and equipment and $0.5 million expense for impairment on assets held for sale.

Net cash used in investing activities

Net cash used in investing activities for the year ended December 31, 2022 was $3.4 million compared to $2.2 million for the year ended December 31, 2021. Net

cash in investing activities during each of these periods consists primarily of purchases of fixed assets and proceeds received from sale of equipment respectively. 

Net cash provided by financing activities

Net cash provided by financing activities for the year ended December 31, 2022 consisted of $6.5 million net proceeds from ATM shares sales and $5.9 million net
proceeds from the loan we secured in September 2022. Net cash provided by financing activities for the year ended December 31, 2021 consisted of $10.2 million in net
proceeds from ATM share sales.  

As of December 31, 2022, we had total cash of $7.1 million and working capital of $10.9 million. As of the date of this report, we believe that we will 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.

Lease receivable

The Company has an outstanding direct sale-type industrial lease agreement with LINICO Corporation pursuant to which the Company has leased to LINICO the
136,750 square foot recycling facility at 2500 Peru. The lease commenced April 1, 2021 and expires on March 31, 2023. LINICO has agreed to a purchase price of $15.25
million and paid nonrefundable deposits totaling $3.25 million. These non-refundable deposits indicate the lessee’s intention to complete the purchase and are included in
current liabilities until forfeited or applied towards the purchase balance. As of December 31, 2022 the outstanding balance of our lease receivable was $15.5 million. The
Company expects to collect the outstanding balance by March 31, 2023 and therefore, no valuation allowance was recorded.  

Property and equipment, net

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. Upon the retirement
or sale of our property and equipment, the cost and associated accumulated depreciation are removed from the consolidated balance sheet, and the resulting gain or loss is
reflected  on  the  consolidated  statement  of  operations.  Maintenance  and  repair  expenditures  are  expensed  as  incurred  while  major  improvements  that  increase  the
functionality, output or expected life of an asset are capitalized and depreciated over the estimated useful life.

We periodically evaluate our property and equipment assets for indications that the carrying amount of an asset may not be recoverable. At December 31, 2022 and
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.  At  December  31,  2022  and  2021,  we  recognized  write  down  on  the  assets  held  for  sale  to  fair  market  value  of
approximately $0.6 million and $0.5 million, respectively.

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. 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 asset and liability method of accounting for income taxes. Under the asset and 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 two operating leases for real estate. We lease our Reno and McCarran, Nevada spaces under non-cancelable operating leases. The Reno, Nevada
lease expires in 2024. 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. In February 2022, the lease on
Alameda, California facility was terminated.

Finance lease obligation

We currently maintain two finance leases for equipment. In November 2021, we entered into a finance lease for a modular laboratory which expires in October of

2024. Our second finance lease is for warehouse equipment.

Note payable

Aqua Metals Reno, Inc. entered into a $6,000,000 loan agreement with Summit Investment Services, LLC, a Nevada limited liability company as to an undivided

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,  2022
consisted of cash and cash equivalents. 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:
Reno, NV

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, 2022 and 2021,
and  the  related  consolidated  statements  of  operations,  stockholders'  equity  and  cash  flows,  for  each  of  the  two  years  in  the  period  ended  December  31,  2022,  and  the
related  notes  (collectively  referred  to  as  the  "consolidated  financial  statements").    In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material
respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the two years in the
period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

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 Lease Receivable

Critical Audit Matter Description

As described in Note 4 to the consolidated financial statements, the Company has accounted for its Industrial Lease and Option to Purchase Agreement as a sales-type
lease. The lease receivable balance as of December 31, 2022 was approximately $15.5 million.  Given the potential for impairment, the related audit effort to evaluate
management's valuation of the lease receivable 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 lease receivable valuation methodology included the following:

● We  obtained  management's  memo  documenting  the  accounting  treatment  of  the  sales-type  lease  transaction  and  evaluated  management's  approach  and

conclusions for adherence to U.S. generally accepted accounting principles.

● We obtained management's calculation of the receivable and performed the following procedures:

o
o
o

Confirmed the significant terms of the Industrial Lease and Option to Purchase Agreement directly with the counterparty.
Performed corroborative calculations confirming that the inputs and calculations appeared accurate based on the terms of the agreement.
Tested a sample of lease payments for accuracy.

● We evaluated the reasonableness of management's assessment of the collectability of the lease receivable.

We have served as the Company's auditor since 2014.

Organization and Operations

AQUA METALS, INC.
Notes to Consolidated Financial Statements 

Aqua Metals is engaged in the business of applying its commercialized clean, water-based recycling technology principles to develop the clean and cost-efficient recycling
solutions  for  both  lead  and  lithium-ion  (“Li”)  batteries.  Our  recycling  process  is  a  patented  hydro-  and  electrometallurgical  technology  that  is  a  novel,  proprietary  and
patented process we developed and named AquaRefining. AquaRefining is a low-emissions, closed-loop recycling technology that replaces polluting furnaces and hazardous
chemicals  with  electricity-powered  electroplating  to  recover  valuable  metals  and  materials  from  spent  batteries  with  higher  purity,  lower  emissions,  and  with  minimal
waste. The modular “Aqualyzers” cleanly generate ultra-pure metal one atom at a time, closing the sustainability loop for the rapidly growing energy storage economy.

We are in the process of demonstrating that Li AquaRefining, which is fundamentally non-polluting, can create the highest quality and highest yields of recovered minerals
from lithium-ion batteries with lower waste streams and lower costs than existing alternatives. We have already demonstrated at our pilot facility our ability to recover key
valuable minerals in lithium-ion batteries, such as lithium hydroxide, copper, nickel, cobalt, and other compounds in 2022. Our goal is to process commercial quantities of
nickel, cobalt, and copper in a pure metal form that can be sold to the general metals and superalloy markets and can be made into battery precursor compound materials with
known processes already used in the mining industry. We have installed, commissioned, and began to operate the first Li AquaRefining pilot plant at the end of 2022, scaling
towards a commercial demonstration operation through 2023.

Our focus for the lead market is providing equipment and licensing of our lead acid battery recycling technologies in an enabler model which allows us to work with anyone
in the industry globally and address the entire marketplace.  Our focus for the lithium market includes operating our first-of-a-kind lithium battery recycling facility, utilizing
electricity to recycle instead of intensive chemical processes, fossil fuels, or high-temperature furnaces.

Liquidity and Management Plans

The Company generated revenues of $4 thousand and $0.2 million during the years ended December 31, 2022 and December 31, 2021, respectively. The Company had net
losses of $15.4 million and $18.2  million  for  the  years  ended December  31,  2022 and December 31, 2021,  respectively. As  of December  31,  2022,  the  Company’s  cash
balance was $7.1 million. As of the date of this report, the Company believes it will require additional capital in order to fund its current level of ongoing costs over the next
twelve months and move forward with its lithium-ion battery recycling activities.

Summary of Significant Accounting Policies

Basis of presentation and consolidation

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

Use of estimates

The  preparation  of  the  consolidated  financial  statements  requires  management  of  the  Company  to  make  a  number  of  estimates  and  assumptions  relating  to  the  reported
amount  of  assets  and  liabilities  and  the  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  consolidated  financial  statements,  and  the  reported  amounts  of
expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, valuation allowances
for deferred tax assets, the determination of 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, 2022,  the  Company  had no  trade  accounts  receivable  balance  and  has not  created  a  reserve  for  doubtful
accounts. The total accounts receivable balance as of  December 31, 2022 and December 31, 2021 consisted of proceeds from the sale of equipment.

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, net

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,  2022 and 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.
At  December 31, 2022 and 2021, we recognized a write-down on the assets held for sale to fair market value of approximately $0.6 million and $0.5 million, respectively.

Table of Contents

Intellectual property, net

Intellectual  property  consists  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,  2022  and 2021,  the  Company  determined  that  the
estimated life of the intellectual property properly reflected the current remaining economic life of the asset.

Investment in LINICO

Investments,  which may be  made  from  time  to  time  for  strategic  reasons  (and not  to  engage  in  the  business  of  investments)  are  included  in  non-current  assets  in  the
consolidated  balance  sheets.  Investments  are  recorded  at  cost  and  the  Company  analyzes  the  value  of  investments  on  a  quarterly  basis.  The  nature  and  timing  of  the
Company’s investments will depend on available capital at any particular time and the investment opportunities identified and available to the Company.

Leases

The  Company  determines  if  an  arrangement  is  a  lease  at  inception.  Operating  lease  right-of-use  assets  (“ROU  assets”)  and  short-term  and  long-term  lease  liabilities  are
included  in  the  consolidated  balance  sheets.  ROU  assets  represent  the  right  to  use  an  underlying  asset  for  the  lease  term  and  lease  liabilities  represent  the  Company’s
obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at commencement date based on the present
value of lease payments over the lease term. As most of the Company’s leases do  not provide an implicit rate, the Company uses an incremental borrowing rate based on the
information available at the commencement date in determining the present value of lease payments. The Company’s lease terms may include options to extend or terminate
the lease. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For lease agreements with terms less than 12 months, the Company has
elected the short-term lease measurement and recognition exemption, and the Company recognizes such lease payments on a straight-line basis over the lease term.

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. 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 asset and liability method of accounting for income taxes. Under the asset and 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,  and  accrued  expenses
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, 2022 or December 31, 2021.

Stock-based compensation

The  Company  recognizes  compensation  expense  for  stock-based  compensation  in  accordance  with ASC 718  “Compensation  –  Stock  Compensation.”  The  fair  value  of
restricted stock units ("RSUs") is measured on the grant date based on the closing fair market value of our common stock. The resulting cost is recognized over the period
during  which  an  employee  is  required  to  provide  service  in  exchange  for  the  awards,  usually  the  vesting  period,  which  is  generally three  years  for  RSUs.  Stock-based
compensation expense is recognized on a straight-line basis, net of actual forfeitures in the period.

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, 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, 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

Our chief operating decision maker (“CODM”) is the Chief Executive Officer. 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 CODM in deciding how to allocate resources and in assessing performance. The CODM
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  $4,000  and  $173,000  for  the  years  ended   December  31,  2022 and 2021,  respectively,  for  the  sale  of  inventory  to  P.  Kay  Metals.
Revenue from P. Kay Metals represented  100% of total revenue for the years ended December 31, 2022 and 2021. The Company did not have a trade receivable balance as
of   December  31,  2022.  The  Company's  trade  accounts  receivable  balance  was  $17,000  as  of   December  31,  2021.  The  accounts  receivable  balance  on  the  Company's
consolidated balance sheets as of  December 31, 2022 and  December 31, 2021 consisted of proceeds from sale of equipment. 

Plant operations and clean up

During  the fourth  quarter  of 2022, the Company reclassified cost of product sales as plant operations and clean up to make the financial statements be more informative.
Prior year amounts have been reclassified for consistency with the current year presentation. The reclassification has no effect on the reported results of operations.

Recent accounting pronouncements

There were no recent accounting pronouncements or changes in accounting pronouncements during the year ended December 31, 2022 that are of significance or potential
significance to the Company.

3.                  Revenue recognition

The Company has historically generated revenues by recycling lead acid batteries (“LABs”) and selling the recovered lead to its customers.

The  Company  was not  in  commercial  production  in 2022  or 2021.  The  nominal  revenue  generated  during  the  years  ended   December  31,  2022 a n d December  31,
2021 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, 2022 and December 31, 2021.

4.

Lease receivable

The Company has entered into an Industrial Lease Agreement with LINICO Corporation, a Nevada corporation, or ("LINICO"), dated February 15, 2021 pursuant to which
the Company has leased to LINICO the 136,750 square foot recycling facility at TRIC. The lease commenced  April 1, 2021 and expires on March  31,  2023. LINICO has
agreed  to  a  purchase  price  of  $15.25  million,  and  paid  a  nonrefundable  deposit  of  $1.25  million  in October 2021,  and  a second  nonrefundable  deposit  of  $2  million  in
October 2022,  per  the  terms  of  the  agreement,  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 completed in 2022. 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. At  the  beginning  of 2022,  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 at the inception 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 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 consolidated statements of operations. For the year ended  December 31, 2022, the Company recognized a reduction in the
lease receivable balance of approximately $920,000 and recorded $76,000 of interest income related to this agreement.

6.                  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, 2022 and 2021, Aqua Metals had assets with a book value of $47,000 and $2.6 million classified as assets held for sale, respectively.

At December 31, 2022 and 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.  During  the  years  ended December  31,  2022 and 2021  we  recognized  a  $0.6  million  and  $0.5  million
impairment of assets held for sale, respectively.

Investments

On February 15, 2021, the Company entered into a Series A Preferred Stock Purchase Agreement with LINICO Corporation, a Nevada 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 $1.5 million, 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. During the first quarter of 2022, 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.

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.

As of  December 31, 2022, the Company maintained two operating leases for real estate. The Company's operating leases have terms of 36 and 37 months and include one or
more options to extend the duration of the agreements. These operating leases are included in "Other assets" on the Company's December 31, 2022  and 2021 consolidated
balance sheets and represent the Company's right to use the underlying assets for the term of the leases. The Company's obligation to make lease payments are included in
"Lease  liability,  current  portion"  and  "Lease  liability,  non-current  portion"  on  the  Company's  December  31,  2022  and 2021  consolidated  balance  sheets.  The  Company
recognized  sublease  income  of  $85,000  and  $509,000  for  the twelve  months  ended December  31,  2022  and   December  31,  2021,  respectively.  The Alameda  lease  and
sublease agreement ended during the first quarter of 2022.

Based on the present value of the lease payments for the remaining lease term of the Company's existing operating leases, as of December 31, 2022, total right-of-use assets
were approximately $0.5 million and operating lease liabilities were approximately $0.5  million. As  of   December  31,  2021,  total  right-of-use  assets  were  approximately
$0.5 million and operating lease liabilities were approximately $0.6 million.

Note payable

On September 30, 2022, Aqua Metals Reno, Inc., our wholly-owned subsidiary, entered into a Loan Agreement with Summit Investment Services, LLC, a Nevada limited
liability company as to an undivided 90.8334% interest, Darren McBride, Trustee of the Arduino 1 Trust, U/A dated April 25, 2022, as to an undivided 8.3333% interest and
Jason Yelowitz, Trustee of the Jason Yelowitz  2006  Trust,  dated March  31,  2006 as  to  an  undivided .8333% interest (collectively, the “Lenders”), pursuant to which the
Lenders provided us with a loan in the amount of $6 million. The loan accrues interest at a fixed annual rate of 8.50%. Interest-only payments are due monthly for the first
twenty-four months and the principal and all unpaid accrued interest is due on September 29, 2024. We have the right to prepay the loan at any time, provided that we must
pay guaranteed minimum interest of $255,000 (6-months of interest). The Loan Agreement includes representations, warranties, and affirmative and negative covenants that
are customary of institutional loan agreements. The loan is collateralized by a first priority lien interest on our land and recycling facility at TRIC that is expected to sell
before March 31, 2023 to LINICO as disclosed in Note 4 of the consolidated financial statements. Upon the completion of the sale, the commitments and obligations per our
loan agreement with the Lenders will terminate, and all amounts then outstanding will become payable. The costs associated with obtaining the loan were recorded as a
reduction to the carrying amount of the note and are being amortized over the life of the loan.

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

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,  2022 and December  31,  2021.  The  net
valuation allowance increased by approximately $3.0 million during the year ended  December 31, 2022.  The  increase  in  net  valuation  allowance  primarily  relates  to  net
operating losses generated during 2022.

At December 31, 2022, the Company has Federal and California net operating loss carryforwards of approximately $153.4 million and $4.1 million, respectively, which will
begin to expire on 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, 2022, the Company had research and development credits carryforward of approximately $0.5 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 on  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, 2022,  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,  2022,  the  Company’s  total  amount  of
unrecognized tax benefit was approximately $0.3  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 Company files income tax returns with the United States federal government and the State of California. The Company’s tax returns for 2019, 2020  and 2021 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 a maximum of 4% employer matching contributions with immediate vesting. We recognized $111,000 and $71,000 of expenses related to
employer contributions for the 401(k) savings plan during the years ended  December 31, 2022 and 2021, respectively.

19.                 Subsequent events

On February  1,  2023, Aqua  Metals  Reno,  Inc.,  our  wholly-owned  subsidiary,  entered  into  a  Loan Agreement  with  Summit  Investment  Services,  LLC,  a  Nevada  limited
liability company (the “Lender”), pursuant to which the Lender provided us with a loan in the amount of $3 million. The loan proceeds were used to purchase a building
located at 2999 Waltham Way McCarran, NV  89434 (the “Building”). The loan accrues interest at a fixed annual rate of 9.50%. Interest-only payments are due monthly for
the first twenty-four months and the principal and all unpaid interest is due on March 1, 2025. We have the right to prepay the loan at any time, provided that we must pay
guaranteed minimum interest of $213,750 (9-months of interest). The Loan Agreement includes representations, warranties, and affirmative and negative covenants that are
customary of institutional loan agreements. The loan is collateralized by a first priority lien on the Building and site improvements, and is guaranteed by Aqua Metals, Inc.

On February 1, 2023, Aqua Metals Reno, Inc., our wholly-owned subsidiary, completed the purchase of a 21,000 square foot building, from an unaffiliated party, located on
2999 Waltham Way McCarran, Nevada 89434 for $4.275 million.

The  Company  has  evaluated  subsequent  events  through  the  date  which  the  consolidated  financial  statements  were  available  to  be  issued.  Based  upon  this  review,  the
Company did not identify any other subsequent events that would have required adjustment or disclosure.

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, 2022
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, 2022 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, 2022 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, 2022, and based on that evaluation, management concluded that our internal control over
financial reporting was effective as of December 31, 2022.

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.

knowledge,  as  of  the  date  hereof,  based  upon  reasonable  inquiry  by  such  Borrower,  indirect  interest,  of  any  nature  whatsoever  in  any  Borrower  or  any  Guarantor,  as

ARTICLE III
CONDITIONS AND DISBURSEMENT

Lender's satisfaction of all the conditions listed in Exhibit B attached hereto and incorporated herein by reference.

SECTION 3.2   DISBURSEMENT. Once all conditions have been satisfied, the proceeds of the Term Loan, when qualified for disbursement, shall be disbursed by

ARTICLE IV
AFFIRMATIVE COVENANTS

Borrower covenants that until payment in full of all obligations of Borrower subject hereto, Borrower shall, unless Lender otherwise consents in writing:

SECTION 4.1.   PUNCTUAL PAYMENTS. Punctually pay all principal, interest, fees or other liabilities due under any of the Loan Documents at the times and
place and in the manner specified therein, and immediately upon demand by Lender, the amount by which the outstanding principal balance of any credit subject hereto at
any time exceeds any limitation on borrowings applicable thereto.

SECTION 4.2.   ACCOUNTING RECORDS. Maintain adequate books and records in accordance with generally accepted accounting principles and consistently
applied practice, and permit any representative of Lender, during normal business hours upon reasonable request (or at any time during the existence of an Event of Default),
to inspect, audit and examine such books and records, to make extracts thereof and copies of the same, and to inspect the properties of Borrower.

SECTION 4.3.   BUSINESS CONTINUITY. Conduct its business in substantially the same manner and locations as such business is now and has previously been

SECTION 4.5.   FINANCIAL INFORMATION. Within a reasonable time of receipt of a request from Lender, provide to Lender promptly, in form and detail
satisfactory  to  Lender,  such  information  regarding  the  business  affairs  and  financial  condition  of  Borrower  which  Lender  may  reasonably  request,  including,  without
limitation, tax returns (and all schedules thereto), tax information regarding the Property, and financial statements of Borrower.

6

 
 
 
 
 
 
 
 
 
 
 
 
SECTION 4.6.   COMPLIANCE. Preserve and maintain all licenses, permits, governmental approvals, rights, privileges and franchises necessary for the conduct of
its  business  or  operation  of  the  Property;  and  comply  with  the  provisions  of  all  documents  pursuant  to  which  Borrower  is  organized  and/or  which  govern  Borrower's
continued  existence  and  with  the  requirements  of  all  laws,  rules,  regulations  and  orders  of  any  governmental  authority  applicable  to  Borrower,  its  business,  and/or  the
Property, except to the extent that the failure to comply with the foregoing could not reasonably result in a material adverse effect.

SECTION 4.7.   INSURANCE. Maintain and keep in force insurance of the types and in amounts customarily carried by persons or entities with similar assets,
including but not limited to extended coverage, public liability, flood (if in a designated flood zone), property damage and workers' compensation, with all such insurance
carried with companies and in amounts satisfactory to Lender, naming Lender as loss payee or additional insured, if and as Lender may require, and deliver to Lender from
time to time at Lender's request schedules setting forth all insurance then in effect.

SECTION 4.8.   TAXES AND OTHER LIABILITIES. Pay and discharge prior to delinquency any and all indebtedness, obligations, assessments and taxes, both
real or personal, including without limitation federal and state income taxes and state and local property taxes and assessments, except (a) such as Borrower may in good
faith contest or as to which a bona fide dispute may arise, and (b) for which Borrower has made provision, to Lender's satisfaction, for eventual payment thereof in the event
Borrower is obligated to make such payment.

SECTION 4.9.   NOTICE OF DEFAULT AND OTHER NOTICES.

( a )   Notice of Default. Furnish to Lender promptly upon becoming aware of the existence of any  condition  or  event  which  constitutes  an  Event  of  Default  (as
defined in the Loan Documents) or any event which, upon the giving of notice or lapse of time or both, may become an Event of Default, written notice specifying the nature
and period of existence thereof and the action which Borrower is taking or proposes to take with respect thereto.

(b)   Other Notices. Promptly notify Lender in writing of (i) any material adverse change in Borrower’s financial condition, its business, or the Property; (ii) any
material default under any material agreement, contract or other instrument to which Borrower is a party or by which any of its properties are bound, or any acceleration of
the maturity of any indebtedness owing by Borrower; (iii) any material adverse claim against or affecting Borrower or any part of its properties; (iv) the commencement of,
and any material determination in, any litigation with any third party or any proceeding before any governmental agency or unit affecting Borrower; (v) at least 30 days prior
thereto, any change in Borrower's name or address as shown herein, and/or any change in Borrower's structure; and (vi) any termination or cancellation of any insurance
policy which Borrower is required to maintain, or any uninsured or partially uninsured loss through liability or property damage, or through fire, theft or any other cause
affecting Borrower's property in excess of an aggregate of $250,000.00.

7

 
 
 
 
 
 
 
 
SECTION 4.10.   ADDITIONAL THIRD-PARTY FEES. Pay any and all third‑party fees incurred by Lender in connection with the credit facilities hereunder.

SECTION  4.11.      LATE  CHARGE.  Borrower  recognizes  that  Default  in  making  the  installment  monthly  payments  when  due  hereunder  will  result  in  Lender
incurring additional expense in servicing the Loan, in loss to Lender of the use of the money due and in frustration to Lender in meeting its loan commitments.. Borrower
agrees that if, for any reason, any monthly installment of interest shall not be received by Lender within ten (10) days of its due date, Lender shall be entitled to damages for
the detriment caused thereby. Borrower therefore agrees to pay Lender a late charge of ten percent (10%) of such installment, but not including the final payment, or the
maximum amount allowed by law, whichever is less, such late charge to be immediately due and payable without notice or demand by Lender. Borrower will pay this late
charge only once for each late installment payment, but not including the final payment. This Section and the amounts for which it provides shall not limit Lender's right,
under this Note, the Deed of Trust, or otherwise, to compel prompt performance thereunder. Lender's failure to collect such late charges shall not constitute a waiver of
Lender's right to require payment of such late charges for past or future Defaults. Any late charge shall be in addition to all other rights and remedies available to Lender
upon the occurrence of a default under the Loan Documents. BORROWER ACKNOWLEDGES AND AGREES THAT IT WOULD BE EXTREMELY DIFFICULT OR
IMPRACTICABLE  TO  FIX  THE  ACTUAL  DAMAGES  RESULTING  FROM  BORROWER'S  FAILURE  TO  PAY  AMOUNTS  WHEN  DUE  AND  THEREFORE,
SHALL  PAY  SUCH  LATE  CHARGES  NOT AS A  PENALTY,  BUT  FOR  THE  PURPOSE  OF  DEFRAYING  THE  EXPENSES  INCIDENT  TO  SERVICING  THE
LOAN AND HANDLING AMOUNTS PAST DUE. FURTHER, BORROWER AGREES THAT THE LATE CHARGES SET FORTH HEREIN ARE A REASONABLE
ESTIMATE  OF  THE  DAMAGES  TO  LENDER.  THE  LATE  CHARGES  SHALL  BE  PAYABLE  BY  BORROWER  WITHOUT  PREJUDICE  TO  THE  RIGHTS  OF
LENDER TO COLLECT ANY OTHER AMOUNTS TO BE PAID UNDER THIS NOTE OR THE DEED OF TRUST.

SECTION 4.12   DEFAULT INTEREST. Following the occurrence and during the continuance of an Event of Default, interest on any amounts then outstanding
shall be increased automatically from the date of the Event of Default until cured to thirteen percent (13%) per annum (“Default Interest”), and all outstanding amounts due,
including unpaid Regular Interest shall continue to accrue interest from the date of such Event of Default at the Default Interest rate until such Event of Default is cured or
waived. Borrower acknowledges and agrees that the application of Default Interest may result in the compounding of interest.

ARTICLE V
NEGATIVE COVENANTS

Borrower further covenants that so long as any liabilities (whether direct or contingent, liquidated or unliquidated) of Borrower to Lender under any of the Loan

Documents remain outstanding, and until payment in full of all obligations of Borrower subject hereto, Borrower will not without Lender's prior written consent:

SECTION 5.1.   USE OF FUNDS. Use any of the proceeds of any credit extended hereunder except for the purposes stated in this Agreement.

8

 
 
 
 
 
 
 
 
SECTION 5.2.   OTHER INDEBTEDNESS. Create, incur, assume or permit to exist any indebtedness or liabilities resulting from borrowings, loans or advances,

additional indebtedness or liabilities in an aggregate amount not to exceed $250,000.00 at any time.

SECTION  5.3.      GUARANTIES.  Guarantee  or  become  liable  in  any  way  as  surety,  endorser  (other  than  as  endorser  of  negotiable  instruments  for  deposit  or
collection in the ordinary course of business), accommodation endorser or otherwise for, nor pledge or hypothecate any assets of Borrower as security for, any liabilities or
obligations of any other person or entity, except any of the foregoing in favor of Lender.

SECTION 5.4.   LOANS. Other than in the ordinary course of business, make any loans or advances to or investments in any person or entity.

SECTION 5.5.   PLEDGE OF ASSETS. Mortgage, pledge, grant or permit to exist a security interest in, or lien upon, all or any portion of the Property except (a)

security interests required by the Loan Documents, and (b) liens for non-delinquent taxes and taxes contested in good faith; and (c) any of the foregoing in favor of Lender.

SECTION  5.6.      GOVERNMENT  INTERVENTION.  Permit  the  assertion  or  making  of  any  seizure,  vesting  or  intervention  by  or  under  authority  of  any

governmental entity.

SECTION 5.7.   MERGER, CONSOLIDATION AND TRANSFER OF ASSETS. If Borrower or any signatory who signs on its behalf is a corporation, limited
liability company, partnership, or trust, Borrower shall not: (a) merge or consolidate with any other entity; (b) dissolve, enter into revoked status, or make any change in the
nature  of  Borrower’s  structure;  or  (c)  make  or  permit  to  be  made  any  change  to  Borrower’s  organizational  documents  that  is  likely  to  have  a  material  adverse  effect  on
Borrower’s ability to own and operate its assets or perform its obligations under the Loan Documents.

ARTICLE VI

SECTION 6.1.   The occurrence of any of the following shall constitute an "Event of Default" under this Agreement:

(a)   Borrower shall fail to pay when due any principal, interest (including Minimum Guaranteed Interest), fees or other amounts payable under any of the Loan

Documents, which failure continues for 10 days after written notice from Lender.

default  shall  continue  for  a  period  of  30  days  after  written  notice  from  Lender;  provided  that  if  the  foregoing  default  requires  additional  time  to  cure  and  Borrower  is
diligently and in good faith acting to cure such default, then Borrower shall have an additional 60 days to cure such default. (d)   The neglect, failure or refusal of Borrower
to keep in full force and effect any permit, license, consent, approval or insurance required hereunder or under the loan Documents.

(g)   Any change in ownership or control of Borrower or any entity or combination of entities that directly or indirectly control Borrower, which change shall be

defined as the sale, transfer or conveyance of any interest in Borrower of an aggregate of forty percent (40%) or more of the total interests in Borrower.

(h)   The dissolution, liquidation, or revocation of Borrower, or any of its managers or members shall take action seeking to effect the dissolution or liquidation of

SECTION 7.5.   RIGHT TO RELEASE AND RECONVEY. To the extent permitted by applicable law, Borrower hereby acknowledges and agrees that Lender

SECTION  7.12      RELATIONSHIP  OF  PARTIES.  The  relationship  between  Borrower  and  Lender  is,  and  at  all  times  shall  remain,  solely  that  of  debtor  and
creditor, and shall not be, or be construed to be, a joint venture, equity venture, partnership or other relationship of any nature. Borrower and Lender warrant to each other
that they shall make no statement, orally or in writing, or take or omit any action which could be implied by an ordinary, reasonable, prudent third party as evidence of a
joint venture, equity venture or partnership between Borrower and Lender. Lender neither undertakes nor assumes any responsibility or duty to Borrower or to any other
person with respect to the Property or the transactions contemplated by the Loan Documents, except as expressly provided in the Loan Documents. Notwithstanding any
other provision of the Loan Documents and without limiting the foregoing: (a) Lender is not, and shall not be construed as, a partner, joint venturer, alter ego, manager,
controlling person or other business associate or participant of any kind of Borrower or its partners or members, if applicable, and Lender does not intend to ever assume
such status; (b) Lender shall in no event be liable for any debts, expenses or losses incurred or sustained by Borrower; (c) Lender's activities in connection with the Loan
Documents shall not be outside the scope of the activities of a lender within the meaning of NRS 41.590 and other laws of the State of Nevada, and Lender does not intend
to  ever  assume  any  responsibility  to  any  person  for  the  quality,  suitability,  safety  or  condition  of  the  Property;  and  (d)  Lender  shall  not  be  deemed  responsible  for  or  a
participant in any acts, omissions or decisions of Borrower or its partners or members. In no event shall Lender be liable for any of the debts, obligations or liabilities of
Borrower  or  of  its  members  or  owners  as  a  result  of  the  execution  and  delivery  of  the  Loan  Documents;  and  in  no  event  shall  Lender  be  liable  for  any  contributions  to
Borrower,  and  Borrower  agrees  to  indemnify,  defend  and  hold  Lender  harmless  from  any  claim,  cause  of  action,  settlement,  judgment,  award  or  damage,  including
reasonable attorneys' fees and costs, arising from a breach of this warranty.

SECTION 7.13   INDEMNIFICATION. Borrower will indemnify and hold Lender harmless from any loss, liability, damages, judgments, and costs of any kind
relating to or arising directly or indirectly out of (a) this Agreement or any other Loan Document, (b) any credit extended or committed by Lender to Borrower hereunder,
and (c) any litigation or proceeding related to or arising out of any of the Loan Document or any such credit. This indemnity includes but is not limited to attorneys' fees.
This indemnity extends to Lender, its affiliates, members, managers, directors, officers, employees, agents, successors, attorneys, and assigns. This indemnity will survive
repayment of Borrower’s obligations to Lender.

SECTION 7.14   COMMISSION AND BROKERAGE FEE.  Borrower, at its sole cost and expense, has authorized Alpen Mortgage as its mortgage loan broker
with  regard  to  this  transaction  (“Broker”).  Neither  Borrower  nor  Lender  has  authorized  any  other  broker  or  finder  to  act  on  behalf  of  the  other  party  with  regard  to  the
consummation  of  this  loan.    Borrower  agrees  to  indemnify,  defend,  protect  and  hold  harmless  Lender  from  and  against  any  and  all  demands,  claims,  losses,  damages,
liabilities,  costs  or  expenses  of  any  kind  or  character  (including  reasonable  attorneys’  fees  and  charges)  arising  out  of  or  resulting  from  any  agreement,  arrangement  or
understanding alleged to have been made by Borrower or on Borrower’s behalf with any other broker or finder in connection with the Loan.  Lender agrees to indemnify,
defend, protect and hold harmless Borrower from and against any and all demands, claims, losses, damages, liabilities, costs or expenses of any kind or character (including
reasonable attorneys’ fees and charges) arising out of or resulting from any agreement, arrangement or understanding alleged to have been made by Lender or on Lender’s
behalf with any other broker or finder in connection with the Loan.  Notwithstanding anything to the contrary contained herein, this Section 7.14 shall survive the making
and repayment of the Loan and the expiration or termination of this Agreement.

14

 
 
 
 
 
SECTION 7.15   VOLUNTARY AGREEMENT; ADVICE FROM INDEPENDENT COUNSEL. Borrower represents to Lender that it has received independent
legal advice with regard to this transaction, or has had ample opportunity to do so, and has satisfied itself with regard to any inquiry or investigation relating to the legal and
tax implications of this transactions. Borrower has not relied on any statements or advice of Lender or Lender’s counsel. This Agreement was prepared and entered into out
of the free will of the parties and pursuant to arm's length negotiations, and the parties believe this Agreement and the other Loan Documents to be fair. Lender has not taken
advantage of Borrower by threats, intimidation, overreaching, unconscionable conduct, or otherwise, and Borrower is proceeding in this transaction voluntarily in what it
perceives to be in its own best interests. Having been negotiated by the parties, this Agreement shall not be construed against any one party for drafting it or any particular
provision, but shall be construed as if both parties jointly prepared this Agreement and any uncertainty or ambiguity shall not be interpreted against any one party.

SECTION 7.16   APPROVAL STANDARD; EFFECT OF APPROVAL.  Except as otherwise provided herein, whenever Lender's consent or approval is required
in this Agreement, such consent or approval may be given or withheld in Lender's sole and absolute discretion. Lender's approval of any matter in connection with the Loan
shall be for the sole purpose of protecting Lender's security and rights. No such approval shall result in a waiver of any default of Borrower. In no event shall Lender's
approval be a representation of any kind with regard to the matter being approved. No consent or approval shall be effective unless the same is expressly set forth in writing
from Lender. In no event shall any other act nor any omission on the part of Lender be construed as a consent or approval or serve to later estop Lender's right to withhold its
consent or approval as to a particular matter. Anything contained in this Agreement and the other Loan Documents to the contrary notwithstanding, when Lender’s consent
or approval is required in this Agreement or the other Loan Documents, such consent only requires the consent of Summit Investment Services, LLC, and not the consent of
any other Lender.

SECTION 7.17   . SUPPLEMENTAL AGREEMENT. The provisions of this Agreement are not intended to supersede the provisions of the Deed of Trust but shall
be construed as supplemental thereto. This Agreement, and all representations and warranties contained herein, shall remain in effect until all amounts due under the Loan
Documents have been paid in full.

SECTION 7.18   SURVIVAL. This Agreement, and all representations, warranties and covenants contained herein, shall remain in effect until the Loan has been

paid in full.

SECTION 7.19   JOINT AND SEVERAL LIABILITY. If Borrower consists of more than one person or entity, their liability shall be joint and several, and the

compromise of any claim with, or the release of, any Borrower shall not constitute a compromise with, or a release of, any other Borrower.

SECTION 7.20   ENTIRE AGREEMENT; AMENDMENT. This Agreement and the other Loan Documents constitute the entire agreement between Borrower and
Lender with respect to each credit subject hereto and supersede all prior negotiations, communications, discussions and correspondence concerning the subject matter hereof.
This Agreement may be amended or modified only in writing signed by each party hereto.
