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.

Aqua Metals has a history of battery recycling, having first owned and operated a pilot lead acid battery recycling facility between 2017 and 2019. This breakthrough
technology was initially applied in the lead acid battery (LAB) recycling industry, building the first integrated recycling system for breaking LAB and recovering pure metal.
In  2019,  we  operated  our  demonstration AquaRefinery  at  commercial  quantity  production  levels  and  produced  over  35,000  ‘AquaRefined’  ingots  operating  twenty-four
hours a day, seven days a week for sustained periods of time.

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  the  Tahoe-Reno  Industrial  Center  (TRIC)  focused  on
applying our proven technology to LiB recycling research, 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, cobalt and manganese dioxide from lithium-ion battery ‘black
mass’ at bench scale 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 enable 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 sustainable 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  and  more  sustainable  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 renewable electricity as the reagent 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.

In  February  2023,  we  acquired  a  five-acre  recycling  campus  at  the  Tahoe  Reno  Industrial  Center  (TRIC).  When  fully  developed,  the  facility  we  envision  is
designed to process up to 10,000 tonnes of lithium-ion battery material each year using our proprietary Li AquaRefining technology. Subject to our receipt of the required
additional capital, we expect to complete development of phase one, including all equipment installation, by mid-2024 and to commence the commissioning and operation at
the new campus in the second half of 2024. The Company is planning for a phased development of the campus, beginning with the already commenced redevelopment of an
existing building on-site into the first commercial-scale Li AquaRefinery, targeting 3,000 tons per annum (tpa) capacity in phase one. In January through March of 2024, we
have made significant progress on the construction of the planned first phase of the commercial Li AquaRefinery.

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 Aqua  Metals  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.

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 enabling domestically produced, sustainably produced, recycled metals to enter the supply chain and lower sole 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.

We believe Aqua Metals' regenerative electro-hydrometallurgical recycling method potentially offers a substantial improvement over traditional  pyrometallurgical
and  hydrometallurgical  recycling  techniques,  which  produce  much  higher  emissions,  lower  recovery  rates,  and  significant  landfill  waste.  We  believe  the AquaRefining
process has the potential to vastly reduce the environmental impact of recycling lithium batteries as compared to other processes while providing a higher yield of high-
purity metals essential for the burgeoning US battery manufacturing industry. 

We are in the process of demonstrating that Li AquaRefining 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 the TRIC, our goal
is  to  demonstrate  our  ability  to  process  commercial  quantities  of  high-purity  lithium  hydroxide  and/or  carbonate,  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  various  advanced  manufacturing  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 and the Shanghai Metals Exchange
(SHME) in China also trades these elements. 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 where recycled mineral content achieves up to 90% of new LAB batteries in a mature industry, lithium and related metals recycling currently
achieves only 1-3% recycled mineral content of new LiB batteries, 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

According to Grand View Research, annual lead acid battery sales are expected to grow 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 15 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.  Even  the  cleanest  incumbent  lead  recycling  operations  produce  more  pollution  and  worker  safety  challenges  than  our  lead
AquaRefining alternative. We believe that further aging of incumbent facilities coupled with ever tightening pollution and worker safety regulations will drive a demand in
all markets for less polluting LAB recycling processes.

The Lithium Battery Market

Global demand for Li-ion batteries is expected to soar over the next decade, with the number of GWh required increasing from about 700 GWh in 2022 to around 4.7
TWh by 2030 (Figure 1 below). Batteries for mobility applications, such as electric vehicles (EVs), will account for the vast bulk of demand in 2030—about 4,300 GWh; an
unsurprising trend seeing that mobility is growing rapidly. This is largely driven by three major drivers:

● A  regulatory  shift  toward  sustainability,  which  includes  new  net-zero  targets  and  guidelines,  including  Europe’s  “Fit  for  55”  program,  the  US  Inflation
Reduction Act, the 2035 ban of internal combustion engine (ICE) vehicles in the EU and in the State of California in the U.S., and India’s Faster Adoption and
Manufacture of Hybrid and Electric Vehicles Scheme.

● Greater customer adoption rates and increased consumer demand for greener technologies (up to 90 percent of total passenger car sales will involve EVs in

selected countries by 2030).

● Announcements by 13 of the top 15 OEMs to discontinue production of ICE vehicles and achieve new emission-reduction targets. 

Figure 1: Growth of the Li-ion Battery Market Battery

Battery energy storage systems (BESS) are expected to have a CAGR of 30 percent, and the GWh required to power these applications in 2030 will be comparable to
the GWh needed for all applications today. China could account for 45 percent of total Li-ion demand in 2025 and 40 percent in 2030—most battery-chain segments are
already mature in that country. Nevertheless, growth is expected to be highest globally in the EU and the United States, driven by recent regulatory changes, as well as a
general trend toward localization of supply chains. In total, at least 120 to 150 new battery factories will need to be built between now and 2030 globally to have sufficient
capacity  to  meet  predicted  demand.  In  line  with  the  surging  demand  for  Li-ion  batteries  across  industries,  it  is  projected  that  revenues  along  the  entire  value  chain  will
increase 5-fold, from about $85 billion in 2022 to over $400 billion in 2030 (Figure 2). Active materials and cell manufacturing may have the largest revenue pools. Mining
is  not  the  only  option  for  sourcing  battery  materials  since  recycling  is  also  an  option. Although  the  recycling  segment  is  expected  to  be  relatively  small  in  2030,  it  is
projected to grow more than three-fold in the following decade, when more batteries reach their end-of-life and greater quantities of manufacturing scrap material become
available for recycling.

Figure 2: Li-ion Revenue Opportunities through 2030

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  under  development  and  early  deployments  have  begun.  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,  only  a  small  fraction  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 available 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.

Black Mass

        Lithium-ion batteries are comprised of valuable metals such as lithium, copper, manganese, cobalt, and nickel. Once a battery is retired, the batteries can be collected,
fully discharged, then shredded and base metals are separated to prepare them for recycling. This shiny, metallic mixture is what is called ‘black mass’—and it contains all
the valuable metals that make up battery anodes and cathodes, the most expensive parts of a battery and the companies that collect and process batteries into black mass
are referred to as ‘shredders’. The typical black color is due to the high concentrations of graphite contained in the anodes of batteries, which has a very dark black color.
Black mass makes up about 40-50% of the total weight of an EV battery. Materials like the binder, copper, electrolytes, plastics, aluminum, and steel have been physically
separated out by shredders before being recycled.

5

 
 
 
 
 
 
 
 
Table of Contents

There are two main processes to producing black mass:

1. Pyrometallurgy: some black mass producers will use high temperatures to burn off unwanted materials like plastics and remaining electrolyte. This can create

hazardous emissions and waste that must be captured or mitigated, and result in less recovered material.

2. Hydrometallurgy: many producers use solution-based techniques—using water, chemicals and electricity to crush and separate the materials from a battery.

This eliminates the need for polluting furnaces and energy intensive processing, creating a lower-carbon black mass.

       Aqua Metals specifically partners with producers that use non-pyro processes in order to create black mass to meet their own objectives for creating low-carbon recycled
materials. The exact composition of black mass can vary considerably based on a number of factors. To start, there are many different types of lithium-ion batteries and
manufacturing scrap forms, which will revert back to a mix of different elements and different ratios, including lithium, nickel, iron, titanium, copper, cobalt, manganese,
and others (their use of lithium is the commonality).

       Each manufacturer also has their own specific ‘recipe’ for their cathodes, cell type/form factors, as well as module type and pack assembly for different applications
(cell phones, laptops, electric vehicles, etc.). Currently, the most popular types of lithium-ion batteries in the world incorporate significant amounts of nickel, cobalt, lithium,
and manganese—so black mass produced today will typically have varying concentrations of each.

AquaRefining Process

We developed AquaRefining to be a cleaner and modular alternative to smelting and chemical-based recycling methods. 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 electrochemical 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 subsequently in our pilot facility that our lithium battery AquaRefining process can generate cobalt, lithium hydroxide or
carbonate, 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, and 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.

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  hydrometallurgical  and  electrochemical  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.

We are applying our sustainable 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.  We  expect  to  recover  lithium  hydroxide  or  lithium  carbonate,  copper,  nickel,  cobalt,  and  other  compounds  in  a  salable  form  to  either  be  sold  directly  to
lithium battery CAM manufactures or the commodities market. 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 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. Throughout 2023 and now into 2024, we have demonstrated at our
pilot  facility  our  ability  to  recover  key  valuable  minerals  in  lithium-ion  batteries,  such  as  lithium  hydroxide  or  lithium  carbonate,  copper,  nickel,  cobalt,  and  other
compounds. 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 operated the first Li AquaRefining pilot plant
throughout  2023.  The  location  for  the  pilot  demonstration  facility  is  currently  the  Innovation  Center  with  expansion  to  happen  at  our  new  5-acre  recycling  campus  to
commercial quantities. Once fully completed, our commercial facility is designed to process ~10,000 tonnes / year or more of battery materials, with our first phase, which
would be enough material to build ~100,000 average EVs or ~400,000 average home energy storage systems. We are proceeding with a phased development approach, and
commenced phase one of our campus in 2023, with a target capacity of 3,000 tonnes per year.

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. 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 expansion and progress. 

The market for lithium-ion batteries is global in scale but local in nature and execution, with large differences in local regulation, custom and practice, and access to
transportation and electricity costs. In some regions, it is highly regulated, and in others it is not. Consequently, we are evolving our business model to commercialize our
technology optimally across multiple locations.

Competition

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 materials that typically require further refining before being utilized to manufacture new batteries. 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.

The competitive advantages of the Aqua Metals project include:

● Replaces  furnaces  and  heavy  chemical  use  with  100%  electricity-powered  and  closed-loop  recycling,  creating  fundamentally  non  polluting,  cost-efficient

solution that generates minimal waste

● AquaRefining  recovers  all  valuable  materials,  including  Lithium  Hydroxide,  Lithium  Carbonate,  and  Manganese  Dioxide,  which  are  not  recovered  by

competing methods

Strong IP protection: 73 global patents; 43 patents pending

● Recovers the high-value metals lost in smelting (like lithium and manganese), and produces high purity products
● Only Li-ion recycling method with pathway to net-zero operations
●
● Only electro-hydrometallurgy recycler in North America
●
● Massive and growing global addressable market
● Greenfield opportunity for partnerships and strategic alliances

Safer work environment, less hazardous materials, eliminates constant trainloads of chemicals

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  3  US  patents,  32  international  patents,  and  3  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, Ukraine, and Vietnam. We also have
32  US  and  foreign  patent  applications  pending  with  patent  applications  pending  in  16  additional  non-US  jurisdictions,  across  six  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 or lithium materials using an aqua refining process. Differences in the claim number and
scope are due to local rules and practice as well as the target metal.

We intend to continue to prepare and file domestic and foreign patent applications covering expanding aspects and applications of our technology, as circumstances

warrant.

There can be no assurance that any patents will issue from any of our current or any future applications. Also, any patents that may issue may not survive a legal
challenge to their scope, validity, or enforceability, or provide significant protection for us. Competitors may work around our patents, so they are not infringing. Our patent
portfolio and our existing policy and procedures safeguarding our trade secrets nonetheless may face challenges so that our competitors can copy our AquaRefining process.

Trademark Portfolio

We have filed for trademark registration in the US and foreign countries for the following trademarks:

AQUA METALS (11 foreign countries)
AQUAREFINING (10 foreign countries)
AQMS (US only)

•
•
•
• AQUAREFINERY (9 foreign countries)

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 and Operations

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, 2023, 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 $310,000 of which was derived prior to January 1,2020 at our former LAB recycling facility. In the last two years, the business has been
focused on completing the research and development of the application of our AquaRefining technology to the recycling of lithium-ion batteries and operating a lithium-
ion recycling pilot plant. 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 estimate that we will begin to realize revenues from lithium-ion battery recycling in 2024, 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 build out 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 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 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,  2023,  we  had  total  cash  of  $16.5  million  and  working  capital  of  $13.7  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 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 debt financing or through the sale of equity. 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.

The report of our independent registered public accounting firm for the year ended December 31, 2023 states that there is substantial doubt about our ability to

continue as a going concern within one year after the date that the financial statements are issued.

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. On February 1, 2023, we closed on the
acquisition  financing  and  purchased  the  five-acre  site,  plus  the  existing  21,000  square  foot  building,  and  as  noted  elsewhere,  in  third  quarter  of  2023  we  raised  a  net  of
$22.9 million from the sale of our common stock. We believe the net proceeds will allow us to commence the Phase One build-out of the facility. However, we will need
additional  financing  to  complete  the  build-out  of  Phase  One,  which  we  intend  to  pursue  through  conventional  non-dilutive  loans,  potential  government  backed  debt
offerings, government grants or through the sale of our common stock via our current at-the-market offering. 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 first half of 2024 and to commence operations at the new campus
in the second half of 2024. However, there can be no assurance we will be able to do so.

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 metals from batteries on a small scale, we have not processed recycled
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.

Table of Contents

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 batteries is an established business, to date
virtually  all  recycled  metals  have  been  produced  by  way  of  traditional  smelting  processes.  To  our  knowledge,  no  one  has  successfully  produced  recycled  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
batteries without smelting. Further, there can be no assurance that either we will be able to produce AquaRefined metals from 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.

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. In 2021, we filed a
provisional  patent  for  recovering  high-value  metals  from  recycled  lithium-ion  batteries  to  complement  the  patents  for  AquaRefining.  At  the  end  of  2022  and
throughout 2023, we successfully recovered all valuable materials from spent lithium batteries at production scale using our AquaRefining technology: lithium hydroxide,
copper, nickel, cobalt, and manganese dioxide. We also operated our pilot plant throughout 2023. We are continuing our efforts to improve our Li AquaRefining process;
however, 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,  as  one  of  our  business  strategies,  to  commercially  exploit  our AquaRefining
process  by  licensing  our  technology  to  third  parties  and  entering  into  joint  ventures  and  strategic  relationships  with  parties  involved  in  the  manufacture  and  recycling
of batteries. We are also currently seeking to negotiate agreements with others. However, there can be no assurance we will be able to conclude a licensing agreement with
any  partners,  or  that  we  will  be  able  to  do  so  on  terms  that  benefit  us.  In  2023,  we  exited  our  proposed  collaboration  with  LINICO  by  way  of  the  sale  of  our
LINICO common stock to LINICO’s parent, Comstock Inc., and we ceased the development of recycling operations at the Taiwan facilities of ACME Metals. 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.

Even if our licensees are successful in recycling batteries using our processes, there can be no assurance that the AquaRefined 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  metals.  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, lithium carbonate, copper, and manganese dioxide, we have only recently begun the development of 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 metals 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 initial commercial
operations  involved  the  production  of  lead  compounds  and  plastics  from  recycled  LABs,  and  the  sale  of  lead  bullion  and AquaRefined  lead.  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 metals. 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  metals  from  batteries  in  commercial  quantities  at  a  cost  of
production that will provide us and our proposed licensees with an adequate profit margin.

Our intellectual property rights may not be adequate to protect our business. As of the date of this report, we have 3 issued US patents, 32 international patents,

and 3 international allowances related to our AquaRefining process.

We  also  have  further  patent  applications  pending  in  the  United  States  and  numerous  corresponding  patent  applications  pending  in  16  additional  jurisdictions
relating to certain elements of the technology underlying our AquaRefining process and related apparatus and chemical formulations. However, no assurances can be given
that any patent issued, or any patents issued on our current and any future patent applications, will be sufficiently broad to adequately protect our technology. In addition, we
cannot assure you that any patents issued now or in the future will not be challenged, invalidated, or circumvented.

Even patents issued to us may not stop a competitor from illegally using our patented processes and materials. In such event, we would incur substantial costs and
expenses,  including  lost  time  of  management  in  addressing  and  litigating,  if  necessary,  such  matters. Additionally,  we  rely  upon  a  combination  of  trade  secret  laws  and
nondisclosure  agreements  with  third  parties  and  employees  having  access  to  confidential  information  or  receiving  unpatented  proprietary  know-how,  trade  secrets  and
technology to protect our proprietary rights and technology. These laws and agreements provide only limited protection. We can give no assurance that these measures will
adequately protect us from misappropriation of proprietary information.

Our  processes  may  infringe  on  the  intellectual  property  rights  of  others,  which  could  lead  to  costly  disputes  or  disruptions.  The  applied  science  industry  is
characterized by frequent allegations of intellectual property infringement. Though we do not expect to be subject to any of these allegations, any allegation of infringement
could be time consuming and expensive to defend or resolve, result in substantial diversion of management resources, cause suspension of operations or force us to enter into
royalty, license, or other agreements rather than dispute the merits of such allegation. If patent holders or other holders of intellectual property initiate legal proceedings, we
may be forced into protracted and costly litigation. We may not be successful in defending such litigation and may not be able to procure any required royalty or license
agreements on acceptable terms or at all.

Our internal computer systems, or those of our collaborators or other contractors or consultants, may fail or suffer security breaches, which could result in a
material  disruption  of  our  product  development  programs.    Our  internal  computer  systems  and  those  of  our  current  and  any  future  customers,  vendors,  licensees,
collaborators  and  other  contractors  or  consultants  are  vulnerable  to  damage  from  computer  viruses,  unauthorized  access,  natural  disasters,  terrorism,  war  and
telecommunication and electrical failures. While we have not experienced any such material system failure, accident or security breach to date, if such an event were to occur
and cause interruptions in our operations, it could result in a disruption of our research and development and our business operations, whether due to a loss of our trade
secrets or other proprietary information or other similar disruptions. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or
applications,  or  inappropriate  disclosure  of  confidential  or  proprietary  information,  we  could  incur  liability,  our  competitive  position  could  be  harmed  and  the  further
development and commercialization of our recycling technologies could be delayed.

We could be subject to risks caused by misappropriation, misuse, leakage, falsification or intentional or accidental release or loss of information maintained in the
information systems and networks of our company and our customers, vendors, licensees, collaborators and other contractors or consultants, including personal information
of our employees and others, and company and third-party confidential data. In addition, outside parties may attempt to penetrate our systems or those of our customers,
vendors, licensees, collaborators and other contractors or consultants or fraudulently induce our personnel or the personnel of third parties to disclose sensitive information
in  order  to  gain  access  to  our  data  and/or  systems.  We  may  experience  threats  to  our  data  and  systems,  including  malicious  codes  and  viruses,  phishing  and  other
cyberattack.  The  number  and  complexity  of  these  threats  continue  to  increase  over  time.  If  a  material  breach  of,  or  accidental  or  intentional  loss  of  data  from,  our
information  technology  systems  or  those  of  our  customers,  vendors,  licensees,  collaborators  and  other  contractors  or  consultants  occurs,  the  market  perception  of  the
effectiveness of our security measures could be harmed and our reputation and credibility could be damaged. We could be required to expend significant amounts of money
and other resources to repair or replace information systems or networks. In addition, we could be subject to regulatory actions and/or claims made by individuals and groups
in  private  litigation  involving  privacy  issues  related  to  data  collection  and  use  practices  and  other  data  privacy  laws  and  regulations,  including  claims  for  misuse  or
inappropriate disclosure of data, as well as unfair or deceptive practices.

Although we develop and maintain systems and controls designed to prevent these events from occurring, and we have a process to identify and mitigate threats, the
development  and  maintenance  of  these  systems,  controls  and  processes  is  costly  and  requires  ongoing  monitoring  and  updating  as  technologies  change  and  efforts  to
overcome security measures become increasingly sophisticated. Moreover, despite our efforts, the possibility of these events occurring cannot be eliminated entirely. As we
outsource more of our information systems to vendors, engage in more electronic transactions with third parties, and rely more on cloud-based information systems, the
related security risks will increase and we will need to expend additional resources to protect our technology and information systems. In addition, there can be no assurance
that our internal information technology systems or those of our customers, vendors, licensees, collaborators and other contractors or consultants will be sufficient to protect
us against breakdowns, service disruption, data deterioration or loss in the event of a system malfunction, or prevent data from being stolen or corrupted in the event of a
cyberattack, security breach, industrial espionage attacks or insider threat attacks which could result in financial, legal, business or reputational harm.

Risks Relating to Geopolitical, Macroeconomic and Industry Factors

Unfavorable geopolitical and macroeconomic developments could adversely affect our business, financial condition or results of operations. Our business could
be  adversely  affected  by  conditions  in  the  U.S.  and  global  economies,  the  United  States  and  global  financial  markets  and  adverse  geopolitical  and  macroeconomic
developments, including rising inflation rates, the continuing adverse impact of the COVID-19 pandemic, the Ukrainian/Russian and Israeli/Palestinian conflicts and related
sanctions, bank failures, and economic uncertainties related to these conditions. While the COVID-19 pandemic has abated, many of the consequences of the COVID-19
pandemic continue to cause disruption and increased costs for businesses. We believe there continue to be, among other things, supply chain disruptions that are causing
delays in the delivery of equipment and inventory and staffing shortages.

Additionally,  inflation  rates,  particularly  in  the  United  States,  have  increased  to  levels  not  seen  in  years,  and  increased  inflation  may  result  in  increases  in  our
operating costs (including our labor costs), reduced liquidity and limits on our ability to access credit or otherwise raise capital on acceptable terms, if at all. In response to
rising  inflation,  the  U.S.  Federal  Reserve  has  raised,  and  may  again  raise,  interest  rates,  which,  coupled  with  reduced  government  spending  and  volatility  in  financial
markets, may have the effect of further increasing economic uncertainty and heightening these risks.

Further,  financial  markets  around  the  world  experienced  volatility  following  the  invasion  of  Ukraine  by  Russia  in  February  2022  and  the  eruption  of  the
Israeli/Palestinian conflict in October 2023, including as a result of economic sanctions and export controls against Russia and countermeasures taken by Russia. The full
economic and social impact of these sanctions and countermeasures, in addition to the ongoing military conflicts in Ukraine and Gaza, which could conceivably expand,
remains uncertain; however, both the conflicts and related sanctions have resulted and could continue to result in disruptions to trade, commerce, pricing stability, credit
availability, and/or supply chain continuity, in both Europe and globally, and has introduced significant uncertainty into global markets. While we do not currently operate in
Russia, Ukraine or the Middle East, as the adverse effects of these conflicts continue to develop our business and results of operations may be adversely affected.

Any of the foregoing could harm our business. 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 foregoing impacts our results will depend on future developments, which are highly uncertain and cannot be predicted.

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.

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 recyclable batteries and decreasing the price of battery metals
in  times  of  economic  downturn  and  increasing  the  price  of  used  batteries  in  times  of  increasing  demand  of  recyclable  batteries.  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.

Risks Relating to Government Law and Environmental Regulations

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.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 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, lithium hydroxide, and lithium carbonate 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, lithium hydroxide, lithium carbonate 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, 2023, the reported high and low sales prices of our
common stock have ranged from $1.69 to $0.47 through March 22, 2024. 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. 

We  have  received  a  notice  of  delisting  or  failure  to  satisfy  a  continued  listing  rule  from  the  Nasdaq.  On  November  24,  2023,  we  received  a  letter  (from  the
Nasdaq Stock Market, LLC, or Nasdaq, notifying us we had fallen below compliance with respect to the continued listing standard set forth in Rule 5550(a)(2) of the Nasdaq
Listing Rules because the closing bid price of our common stock over the previous 30 consecutive trading-day period had fallen below $1.00 per share. 

Pursuant to the Nasdaq’s letter and Rule 5810(c)(3)(A) of the Nasdaq Listing Rules, we have 180 days from the date of the letter, or until May 22, 2024, to regain
compliance with the minimum bid price requirement in Rule 5550(a)(2) by achieving a closing bid price for our common stock of at least $1.00 per share over a minimum
of 10 consecutive business days. If we do not regain compliance with Rule 5550(a)(2) during the initial 180-day period, we may be eligible for additional time to regain
compliance, subject to our compliance with the Nasdaq’s continued listing requirement for market value of publicly-held shares and all other initial listing standards for The
Nasdaq Capital Market, with the exception of the bid price requirement, and our provision of certain undertakings to the Nasdaq. However, there can be no assurance that we
will be afforded additional time to regain compliance with the minimum bid price requirement following the initial 180-day period. If we are unable to regain compliance
with Nasdaq Listing Rule 5550(a)(2) in a timely manner, the Nasdaq will commence suspension and delisting procedures.

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.

Cybersecurity

At Aqua  Metals,  Inc.,  we  are  committed  to  protecting  our  information  systems,  data,  and  sensitive  information  from  unauthorized  access,  breaches,  and  cyber-
attacks. In this section, we provide an overview of our cybersecurity practices and the measures we have implemented to mitigate cybersecurity risks. We have established
comprehensive cybersecurity policies and procedures that outline the standards and guidelines for safeguarding our digital assets. These policies cover areas such as access
controls,  data  encryption,  network  security,  incident  response,  and  employee  awareness  training.  We  regularly  conduct  thorough  assessments  to  identify  and  evaluate
potential  cybersecurity  risks.  These  assessments  help  us  understand  our  vulnerabilities  and  prioritize  our  efforts  to  mitigate  those  risks.  We  have  implemented  risk
management strategies that include proactive monitoring, and vulnerability scanning. Due to evolving cybersecurity threats, it has and will continue to be difficult to prevent,
detect,  mitigate,  and  remediate  cybersecurity  incidents.  While  we  have  not  experienced  any  material  cybersecurity  threats  or  incidents  as  of  the  date  of  this  Report,  our
cybersecurity program might not be able to prevent or mitigate future successful attacks, threats or incidents.

To  prevent  cyber  threats,  we  have  implemented  a  multi-layered  approach  to  security.  This  includes  firewalls,  intrusion  detection  and  prevention  systems,  and
regular software patching. We also enforce strong password policies and implement two-factor authentication for sensitive systems. In the event of a cybersecurity incident,
we have a well-defined incident response plan in place. This plan includes procedures for containment, investigation, and recovery. We also maintain backups of critical
data to ensure business continuity in case of a breach or system failure.

We  believe  that  cybersecurity  is  a  shared  responsibility.  We  provide  regular  training  and  awareness  programs  to  educate  our  employees  about  best  practices,
potential  threats,  and  their  role  in  maintaining  a  secure  environment.  This  includes  phishing  awareness,  social  engineering  training,  and  ongoing  communication  about
emerging threats.

Governance

Cybersecurity holds a critical position within our risk management framework, drawing significant attention from both our Board and management. Oversight of
cybersecurity risks is vested in our Audit Committee, which regularly receives updates from senior management. These updates, provided as needed, feature insights from
our  leaders  in  information  security.  Topics  covered  include  the  identification  of  existing  and  emerging  cybersecurity  threats,  progress  reports  on  risk  mitigation  efforts,
disclosure of cybersecurity incidents, and updates on key information security initiatives. Furthermore, our Board members engage in informal discussions with management
regarding cybersecurity news and assess any revisions made to our cybersecurity risk management strategies.

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.

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 expires on December 31, 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. This lease was terminated in February 2022.

We owned a 136,750 square foot 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.
As noted in Note 4, on April 26, 2023, the Company sold the real property to Comstock Inc. for $15.25 million. As noted in Note 13, after paying the note payable, the
Company received the net proceeds of approximately $5.7 million.

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 is currently redeveloping the existing facility and installing our first commercial-scale Li AquaRefining
system, which will process an estimated 3,000 tonnes of materials annually. The Company is also exploring plans to develop the remaining land on the property to expand
capacity and operations.

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. When fully developed, the facility is designed, 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
second  quarter  2024  and  to  commence  operations  at  the  new  campus  in  the  third  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 third 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 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, 2023, we issued 3,244,302 shares of common stock pursuant to an At the Market Issuance Sales Agreement ("ATM") for net
proceeds of $3.8 million. We raised a net of $18.3 million in the third quarter of 2023 from the public offering of our common shares and a net of $4.6 million from the sale
of our common stock to Yulho.

Results of Operations for the Fiscal Year Ended December 31, 2023 Compared to the Fiscal Year Ended December 31, 2022

During the years ended December 31, 2023 and December 31, 2022, revenue resulted from the sale of inventory consisting of lead compounds that were generated
during operation of our former TRIC facility. During the years ended December 31, 2023 and December 31, 2022, 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, 2023 and 2022 together with the percentage change from the twelve months ended December 31, 2022 for those items (in thousands).

Except for nominal revenue generated from the sale of lead finished goods, we did not generate revenue during the years ended December 31, 2023 and December
31,  2022.  Plant  activity  during  2023  and  2022  consisted  of  testing  our  lithium-ion  battery  recycling  technology,  developing  the  prototype  system  activities,  and  quickly
advancing from the planning and validation phases to execution and operation of our pilot facility and the build out of our commercial facility.    

Plant  operations  includes  supplies  and  related  costs,  salaries  and  benefits,  consulting  and  outside  services  costs,  depreciation  and  amortization  costs,  insurance,
travel and overhead costs. Plant operations increase approximately $2,323,000 or 59% for the twelve months ended December 31, 2023, as compared to the twelve months
ended  December  31,  2022  as  a  result  of  an  increase  in  payroll  and  payroll  related  fees  of  approximately  $1,702,000,  as  we  hired  additional  staff  to  operate  the  pilot
facility, process black mass and build out of our commercial facility in addition to an increase of $482,000 in legal fees and other service costs.

Research and development cost includes expenditures related to the improvement of the AquaRefining technology and the development of our lithium-ion battery
recycling  process.  During  the  twelve  months  ended  December  31,  2023,  research  and  development  costs  decreased  approximately  $72,000  or  4%  from  the  comparable
period  in  2022.  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. The decrease was driven by moving our focus from R&D
to operating our fully integrated pilot system at the Innovation Center and build out of our commercial facility.

For the year ended December 31, 2023, we recognized a non-cash impairment charge of $4,851,000, subsequent to an analysis of our investment and construction
in progress ("CIP") with regard to our investment in LINICO and ACME Metals. We recognized a loss on the investment in LINICO of approximately $1,400,000 during the
year ended December 31, 2023 as the result of the sale of our LINICO common stock to LINICO's parent Comstock Inc., for $600,000 payable in twelve equal monthly
installments commercing in January 2024. In addition, we recognized a loss of $3,451,000 million related to the ACME CIP as a result of the suspension of the development
of  recycling  operations  at  the ACME  Metals  Taiwanese  facility.    During  2023,  management  has  shifted  focus  away  from  the  original  service  under  the ACME  lead
recycling  license  agreement  to  a  new  primary  focus  on  the  Lithium  recycling  business  as  a  Company. As  a  result,  management  sees  a  decrease  in  the  utilization  of  the
ACME plant and its related operations, and assessed that the future expected cash flows connected with ACME are at or near zero. For the year ended December 31, 2022,
we recognized a write down to fair market value of our assets held for sale of approximately $579,000. We recorded a gain of $700,000 that resulted from the write-off of
plant commitment accrued expenses and $100,000 gain that resulted from the sale of CIP equipment. The gain was offset by a loss on the sale of assets held for sale of
approximately $100,000 and $100,000 bad debt resulting from the sale of the battery breaker.

We recognized a gain on disposal of property, plant and equipment of approximately $23,000 during the twelve months ended December 31, 2023 compared to a
gain of $596,000 for the twelve months ended December 31, 2022. For the twelve months ended December 31, 2022, the gain on property, plant and equipment resulted
from the write-off of plant commitment accrued expenses. Plant clean-up and repair of fire damaged areas were completed by the end of June 30, 2022.

General and administrative expense increased approximately $1,823,000, or 19%, for the twelve months ended December 31, 2023 compared to the twelve months
ended December 31, 2022. The increase in general and administrative expenses for the the twelve months ended December 31, 2023 includes $1,237,000 in payroll and
payroll-related  expenses,  as  well  as  an  increase  of  $780,000  in  travel-related  expenses,  advertising  and  promotion  expenses,  and  overhead  expenses,  offset  by  a
$300,000 decrease in professional fees.

The  following  table  summarizes  our  other  income  and  interest  expense  for  the  years  ended  December  31,  2023  and  December  31,  2022  together  with  the

percentage change in those items (in thousands).

We recognized interest expense of $621,000 for the year ended December 31, 2023 and $125,000 for the year ended December 31, 2022. The increase in interest

expense from the prior year is due to the interest paid on the two loans secured in September 2022 and February 2023.

For  the  year  ended  December  31,  2023  and  December  31,  2022,  and  we  recorded  approximately  $1,147,000  and  $262,000  in  interest  and  other  income,
respectively, an increase of $885,000 or 338%. The $513,000 increase in interest and $242,000 in other revenue is attributable to increased interest on our bank deposits and
miscellaneous income from a non-recurring engineering arrangement with 6K Energy, respectively.

Net  cash  used  in  operating  activities  for  the  years  ended  December  31,  2023  and  December  31,  2022  was  approximately  $3.2  million  and  $10.1  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,  2023,  we
recognized  $12.3  million  proceeds  from  sales  and  leasing  of  building  to  LINICO,  $1.4  million  expense  for  impairment  on  LINICO  investment  and  approximately
$3.5 million expense for impairment on ACME CIP. 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.

Net cash used in investing activities

Net cash used in investing activities for the year ended December 31, 2023 was $9.8 million compared to $3.4 million for  the  year  ended  December  31,  2022.
During these periods, net cash in investing operations primarily includes fixed asset acquisitions, deposits for future fixed asset purchases 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, 2023 consisted of $3.8 million in net proceeds from the sale of Aqua Metals shares
pursuant to the at-the-market offering, or ATM, $2.9 million in net proceeds from the loan agreement secured with the Summit Investment Services, LLC, $18.3 million in
net proceeds from our July 2023 public offering and $4.6 million in net proceeds from the Yulho transaction, offset by the $6 million used to pay off the note payable as
noted in Note 13 and by $1.1 million related to tax withholdings to cover RSU vesting . 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.

As of December 31, 2023, we had total cash of $16.5 million and working capital of $13.7 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  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. 

Due to our lack of revenue from commercial operations, significant losses and need for additional capital, there is substantial doubt about our ability to continue as

a going concern within one year after the date that the financial statements are issued.

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.

Property, plant and equipment, net

Property, plant 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, plant and equipment assets for indications that the carrying amount of an asset may not be recoverable. During the year
2023, management has shifted focus away from the original service under the license agreement (Lead business) to a new focus (Lithium business) as a Company. As such,
management sees a decline in the utilization of the ACME plant and it’s related operations. At December 31, 2023, we recognized write down of approximately $3,451,000
million to equipment under construction that was not yet capitalized related to the ACME CIP as a result of the suspension of the development of recycling operations at the
ACME Metals Taiwanese facility. As of December 31, 2022, 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, we recognized write down on the assets held for sale to
fair market value and $579,000.

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.

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.

Warrants

The Company classifies common stock purchase warrants as equity if the contracts (i) require physical settlement or net-share settlement or (ii) give the Company
a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies any contracts that (i) require net-cash
settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a
choice  of  net-cash  settlement  or  settlement  in  shares  (physical  settlement  or  net-share  settlement),  or  (iii)  contain  reset  provisions  as  either  an  asset  or  a  liability.  The
Company  assesses  classification  of  its  freestanding  derivatives  at  each  reporting  date  to  determine  whether  a  change  in  classification  between  equity  and  liabilities  is
required. 

The value of the common stock purchase warrants are estimated using the Black-Scholes pricing model.

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 using the closing price of the common stock on date of grant date. For stock-options we calculate the fair value of the
award on the date of grant using the Black-Scholes-Merton method; the expense is recognized over the service period for awards to vest. 

For stock price hurdle restricted share units the fair value of the award is calculated on the date of grant using a Monte Carlo simulation model utilizing several key

assumptions, including share price volatility, the risk-free rate of return, the expected dividend yield and other award design features.

The Company recognizes forfeitures as they occur.

Recent accounting pronouncements

See discussion of recent accounting pronouncements in Note 2 of the Consolidated Financial Statements located in Item 8 in this Annual Report.

Material cash requirements

As of December 31, 2023, we and our subsidiaries had outstanding $2,958,000 amount of indebtedness, net of issuance costs, $285,000 interest-only payments are
due in the succeeding 12 months. As of December 31, 2023, our total minimum lease payments was $283,000, of which all is due in the succeeding 12 months. For details
regarding our indebtedness and lease obligations, refer to Note 12, Leases, and Note 13, Note payable, to the consolidated financial statements included elsewhere in this
Annual Report on Form 10-K.

Contractual Obligations and Commitments

Operating lease obligations

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Aqua Metals, Inc.

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheet of Aqua Metals, Inc. (the “Company”) as of December 31, 2023, the related consolidated statements of
operations, stockholders’ equity, and cash flows for the year ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”).  In our
opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and the results of
its operations and its cash flows for the year ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial
statements, the Company has incurred substantial operating losses and negative cash flows from operations since inception that raise substantial doubt about its ability to
continue as a going concern. Management’s plans in regard to this matter are also described in Note 1. The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management.  Our responsibility is to express an opinion on the Company’s financial statements based
on our audit. 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 audit in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the 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 audit, 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 audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to
error or fraud, and performing procedures that respond to those risks.  Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures
in the financial statements.  Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the
overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be
communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially
challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.

Critical Audit Matter – Equity-Classified Warrants

As described in Note 14, the Company issued (1) a warrant to purchase 363,860 shares of the Company's common stock to the underwriter of the Company's July 2023
public offering of common stock and (2) a warrant to purchase 205,761 shares of the Company's common stock to an advisor in connection with the Company’s August
2023 securities purchase agreement with Yulho Co, Ltd. The Company evaluated whether the warrants were in the scope of ASC Topic 480 Distinguishing Liabilities
from Equity, which discusses the accounting for instruments with characteristics of both liabilities and equity. The  application of the requirements in ASC Topic 480, and
the resulting classification conclusion, is dependent on whether certain criteria are met. Based on its analysis, the Company concluded that the warrants did not meet any
of the criteria to be subject to liability classification and are therefore classified as equity.

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

We identified the classification of the warrants as a critical audit matter. The principal considerations for that determination included the complexity and effort required in
identifying all relevant features of and obligations under the instruments for evaluation against the criteria for classification. This required a high degree of auditor effort,
including specialized skills and knowledge, and complex auditor judgment in evaluating the features of and obligations under the warrants and the determination of
whether such features meet the criteria for liability-classification.

The primary procedures we performed to address this critical audit matter included:

● We  obtained  an  understanding  of  management’s  process  for  identifying  and  evaluating  the  critical  terms  of  the  warrant  agreements  in  determining  the

classification.

● With the assistance of professionals in our firm that have specialized skills and knowledge in accounting for debt and equity instruments:

o We evaluated management’s analysis and conclusions regarding the relevant provisions and features of the warrants in light of relevant guidance

and the criteria for classification.

o We read the securities purchase agreement and underlying warrant agreements to identify the relevant features and settlement provisions for our

evaluation.

o We independently evaluated the relevant features and settlement provisions of the warrants under relevant guidance considering the criteria for

classification.

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 the results
of its operations and its cash flows for the year ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

We conducted our audit in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.  Our audit also included performing such other procedures as
we considered necessary in the circumstances.

Our  audit  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 audit 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 audit provides a reasonable basis for our opinion.

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.

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 Going Concern Assessment

For the years ended December 31, 2023 and 2022, the Company reported a net loss of $23.9 million and $15.4 million, respectively, and negative cash from operations of
$3.2 million (inclusive of $12.3 million of non-recurring proceeds from the sale of real estate) and $10.1 million, respectively. As of December 31, 2023, the Company had
cash  and  cash  equivalents  of  approximately  $16.5  million,  a  working  capital  surplus  of  approximately  $13.7  million  and  an  accumulated  deficit  of  $223.2  million.  The
Company  has not  generated  revenues  from  commercial  operations  over  the two  years  ended December  31,  2023, except  for  nominal  sales  of  lead  finished  goods,  and
expects to continue incurring losses for the foreseeable future.

Management believes that the Company does not have sufficient capital resources to sustain operations through at least the next twelve months from the date of this filing.
Additionally, in view of the Company’s expectation to incur significant losses for the foreseeable future it will be required to raise additional capital resources in order to
fund  its  operations,  although  the  availability  of,  and  the  Company’s  access  to  such  resources,  is  not  assured. Accordingly,  management  believes  that  there  is  substantial
doubt regarding the Company’s ability to continue operating as a going concern through the next twelve months from the date of this filing.

The  accompanying  consolidated  financial  statements  have  been  prepared  under  the  assumption  the  Company  will  continue  to  operate  as  a  going  concern,  which
contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments
to reflect the possible future effects on the recoverability and classification of assets or the amounts of liabilities that may result from uncertainty related to the Company’s
ability to continue as a going concern.

Summary of Significant Accounting Policies

Basis of presentation and consolidation

The  accompanying  consolidated  financial  statements  include  those  of  Aqua  Metals,  Inc.  and  its  subsidiaries  (collectively,  the  “Company”  or  “Aqua  Metals”),  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, 2023,  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, 2023 consisted of proceeds from the non-recurring engineering agreement with 6K Energy.

Note receivable

As of December 31, 2023, the Company has a note receivable from the sale of stock in LINICO totaling $600,000. The proceeds will be received over a 12 month installment
starting  in January  2024. As  of December  31,  2023,  we  evaluated  the  need  for  an  allowance  for  credit  loss  using  the  guidelines  set  forth  in ASC 326  CECL,  and  have
determined this note is fully collectible and, therefore, we have not recorded an allowance against this balance.

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, plant and equipment, net

Property, plant and equipment are stated at cost net of accumulated depreciation. Depreciation on property, plant 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, plant and equipment are stated at cost net of accumulated depreciation. Depreciation on property, plant 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, plant and equipment assets for indications that the carrying amount of an asset may not be recoverable. During 2023, management has shifted focus
away from the original service under the ACME lead recycling license agreement to a new primary focus on the Lithium recycling business as a Company. As a result,
management sees a decrease in the utilization of the ACME plant and its related operations, and assessed that the future expected cash flows connected with ACME are at or
near  zero.  Therefore,  at   December  31,  2023,  we  recognized  write  down  of  approximately  $3,451,000  million  to  equipment  under  construction  that  was not  yet
capitalized related to the ACME CIP as a result of the suspension of the development of recycling operations at the ACME Metals Taiwanese facility. As of   December 31,
2022, 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, we recognized a write down of $579,000 on the assets held for sale to their fair market value.

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,  2023  and 2022,  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.  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. As  of December 31, 2023, the Company sold its investment in LINICO and recorded an impairment of $1,400,000  and  a
receivable of $600,000.

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  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 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.

Research and development

The  Company  conducts  research  and  development  activities,  primarily  focusing  on  refining  recycling  processes  to  increase  yield  and  purity  of  recovered  materials.  This
entails experimenting with different techniques, equipment, and operational parameters to enhance efficiency. All 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, 2023 or December 31, 2022.

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.

The fair value of RSU grants with performance conditions is determined using the closing price of our common stock on date of grant. The calculated compensation cost is
adjusted based on an estimate of awards ultimately expected to vest and our assessment of the probable outcome of the performance condition. The fair value of RSU grants
with market conditions is calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected share price volatility,
the risk-free rate of return, the expected dividend yield and other award design features.

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, unvested restricted stock, 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.

Recent accounting pronouncements

Recently issued accounting pronouncements not yet adopted

In November  2023, the  Financial Accounting  Standards  Board  (“FASB”)  issued ASU No. 2023-07,  Improvements  to  Reportable  Segment  Disclosures  (Topic 280).  This
ASU  updates  reportable  segment  disclosure  requirements  by  requiring  disclosures  of  significant  reportable  segment  expenses  that  are  regularly  provided  to  the  Chief
Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss. This ASU also requires disclosure of the title and position of
the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and
deciding  how  to  allocate  resources.  The ASU  is  effective  for  annual  periods  beginning  after  December  15,  2023, and  interim  periods  within  fiscal  years  beginning  after
December 15, 2024. Adoption of the ASU should be applied retrospectively to all prior periods presented in the financial statements. Early adoption is also permitted. This
ASU will likely result in us including the additional required disclosures when adopted. We are currently evaluating the provisions of this ASU and expect to adopt them for
the year ending December 31, 2024.

I n December  2023, the  FASB  issued  ASU No.  2023-09,  Improvements  to  Income  Tax  Disclosures  (Topic 740).  The ASU  requires  disaggregated  information  about  a
reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The ASU is effective on a prospective basis for annual periods
beginning after December 15, 2024. Early adoption is also permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU
will result in the required additional disclosures being included in our consolidated financial statements, once adopted.

Recently adopted accounting pronouncements

On January 1, 2023, the Company adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which
replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement
of  expected  credit  losses  under  the  CECL  methodology  is  applicable  to  financial  assets  measured  at  amortized  cost.  It  also  applies  to  Off-Balance  Sheet  (“OBS”)  credit
exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments and leases
recognized  by  a  lessor  in  accordance  with  Topic 842  on  leases.  The  Company  adopted ASC 326  using  the  modified  retrospective  method.  Results  for  reporting  periods
beginning after January 1, 2023 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. As of its
adoption  date  of January  1,  2023, the  Company  did not  record  a  transition  adjustment  related  to  the  adoption  of ASC 326.  The  adoption  of  this  standard  did not  have  a
material impact on the Company’s financials as of December 31, 2023.

In  August 2020,  the  FASB  issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's
Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which is intended to simplify the accounting for certain
financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity's own equity. The guidance allows for either
full  retrospective  adoption  or  modified  retrospective  adoption.  The  guidance  is  effective  for  the  Company  in  the first  quarter  of  fiscal  year 2024  and  early  adoption  is
permitted. The Company elected early adoption of ASU 2020-06 in the first quarter of its fiscal year 2023 on a modified retrospective basis. There was no material impact to
the financial statements as a result of the adoption.

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 2023  or 2022.  The  nominal  revenue  generated  during  the  years  ended   December  31,  2023 a n d December  31,
2022 resulted from the sale of from the sale of lead finished goods that were generated during operation of the TRIC facility prior to the November  2019 fire at our TRIC
facility.  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, 2023 and December 31, 2022.

Lease receivable

The Company entered into an Industrial Lease Agreement with LINICO Corporation, a Nevada corporation, or ("LINICO"), dated February 15, 2021 pursuant to which the
Company leased to LINICO the 136,750 square foot recycling facility at TRIC. The lease commenced  April 1, 2021 and expired on March  31,  2023. LINICO 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 were applied towards the purchase price. The lease agreement was a triple-net lease pursuant to which LINICO was responsible for
all fixed costs, including maintenance, utilities, insurance, and property taxes. The lease agreement provided 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  contained  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 was reflected on the Company's condensed
consolidated  balance  sheets  as  of June  30,  2021. 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 applied 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. On April 26, 2023, Comstock Inc. exercised their option to
to purchase the facility at which time the purchase price of $15.25 million was applied against the lease receivable. For the year ended  December 31, 2023  and 2022, the
Company recognized a reduction in the lease receivable balance of approximately $15,527,000 and $920,000, respectively, and recorded $24,000 and $76,000 of interest
income, respectively,  related to this agreement. The lease expired in March 2023.

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, 2023 and 2022, Aqua Metals had assets with a book value of nil and $47,000 classified as assets held for sale, respectively.

At December 31, 2023 and 2022, 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, 2023 and 2022  we  recognized nil and $579,000 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 $1,500,000, along with a three-year warrant (“Series A Warrant”) to purchase an additional 500 shares of LINICO Series A Preferred
Stock at an exercise price of $1,000 per share. 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 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 March 2021.

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  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, was a member of the board of directors of Comstock Inc. until  April 5, 2023.

During the year ended December 31, 2023, the Company sold its stock in LINICO and recorded an impairment of $1,400,000 and a receivable of $600,000. The proceeds
will be received over a 12 month installment starting in January 2024.

As of  December 31, 2023, 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, 2023  and 2022 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, 2023 and 2022 consolidated balance sheets. The Alameda lease
and sublease agreement ended during the first quarter of 2022. The Company recognized sublease income of $85,000 for the twelve months ended December 31, 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, 2023, total right-of-use assets
were  approximately  $222,000  and  operating  lease  liabilities  were  approximately  $231,000.  As  of   December  31,  2022,  total  right-of-use  assets  were  approximately
$463,000 and operating lease liabilities were approximately $475,000. For its real estate leases, the Company has elected the practical expedient to not separate a lease into
lease and nonlease components.

The Company currently maintains one finance lease for equipment. In November 2021, the Company entered into a finance lease for a modular laboratory which expires in
October of 2024. The Company's obligation to make finance lease payments are included in "Lease liability, current portion" and "Lease liability, non-current portion" on the
Company's December 31, 2023 and 2022 consolidated balance sheets.

There were no option exercises during the year ended December 31, 2023 and  December 31, 2022, respectively. 

As of December 31, 2023, there is approximately $6.1 million of total unrecognized compensation cost related to the unvested share-based (option and RSU) compensation
arrangements  granted  under  the  stock-based  compensation  plans.  The  remaining  unrecognized  compensation  cost  will  be  recognized  over  a  weighted-average  period  of
2.4 years.

There were no outstanding stock options as of December 31, 2023.

Our policy is to fulfill the required shares for a restricted share vesting by first depleting any available Treasury Stock held by the Company and the remaining outstanding
balance is satisfied with unissued shares.

Stock Price Hurdle Awards

In 2023, the Company granted stock price hurdle restricted share units as a result of the pilot plant commissioning. The stock price hurdle restricted share units expire three
years from the date of grant and vest based on the Corporation’s common stock achieving an absolute stock price hurdles based on a 5-day VWAP at any time over the
three-year term.

The following is a summary of the changes in outstanding stock price hurdle awards share units for 2023:

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,  2023 and December  31,  2022.  The  net
valuation allowance increased by approximately $4.8 million during the year ended  December 31, 2023.  The  increase  in  net  valuation  allowance  primarily  relates  to  net
operating losses generated during 2023.

At December 31, 2023, the Company has Federal and California net operating loss carryforwards of approximately $171.4 million and $4.1 million, respectively, which will
begin to expire on December 31, 2034 for Federal and California purposes. Approximately $146.2 million of federal net operating losses were generated after December 31,
2017 and thus do not expire. Approximately $ 25.2 million of the federal net operating losses and $4.1 million state net operating loss carryforwards will begin to expire in
December 31, 2034, if not utilized.

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, 2023, 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, 2023,  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.

Effective January  1,  2022, the  Company  is  subject  to  mandatory  capitalization  of  Section 174  research  and  development  expenditures.  The  capitalized  expenditures  are
subject to amortization over five years for expenses incurred within the U.S. The Company capitalized $3.6 million and $3.6 million during the years ended December 31,
2023 and December 31, 2022, respectively.

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,  2023,  the  Company’s  total  amount  of
unrecognized tax benefit was approximately $0.5  million, none  of  which  will  affect  the  effective  tax  rate,  if  recognized.  The  Company  does not  expect  its  unrecognized
benefits to change materially over the next twelve months.

The Company files income tax returns with the United States federal government and the State of California. The Company’s tax returns for 2020  to 2022 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 $180,000 and $111,000 of expenses related to

(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, 2023 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. Our
management, with the participation of our chief executive officer and chief financial officer assessed the effectiveness of our internal control over financial reporting as of
December 31, 2023, and based on that evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.

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

Exhibit 4.3

AQUA METALS, INC.

WARRANT TO PURCHASE COMMON STOCK

Original Issue Date:
August 4, 2023

Aqua Metals, Inc., a Delaware corporation (the “Company”), hereby certifies that, for value received, Network 1 Financial Services, Inc. or its permitted registered assigns
(the “Holder”), is entitled to purchase from the Company up to a total of [▪] shares of common stock, $0.001 par value (the “Common Stock”), of the Company (each such
share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise price per share equal to $[▪] (as adjusted from time to time as provided in Section 9
herein, the “Exercise Price”), at any time and from time to time from on or after the date hereof (the “Trigger Date”) and through and including 5:00 P.M., prevailing Pacific
time, on August 4, 202[▪] (the “Expiration Date”), and subject to the following terms and conditions:

1.         Consulting Agreement. This Warrant (this “Warrant”) is issued pursuant to that certain Advisory Agreement dated April 3, 2023 between the Company and

Nexpedia Holdings Co., Ltd., as amended on August 10, 2023 (the “Advisory Agreement”).

2

.         Registration  of  Warrants .  The  Company  shall  register  this  Warrant,  upon  records  to  be  maintained  by  the  Company  for  that  purpose  (the  “Warrant
Register”), in the name of the record Holder (which shall include the initial Holder or, as the case may be, any registered assignee to which this Warrant is permissibly
assigned hereunder) from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise
hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

3 .         Registration of Transfers. The Company shall register the transfer of all or any portion of this Warrant in the Warrant Register, upon (i) surrender of this
Warrant, with the Form of Assignment attached as  Schedule 2 hereto duly completed and signed, to the Company’s transfer agent or to the Company at its address specified
herein (ii) delivery, at the request of the Company, of an opinion of counsel reasonably satisfactory to the Company to the effect that the transfer of such portion of this
Warrant  may  be  made  pursuant  to  an  available  exemption  from  the  registration  requirements  of  the  Securities Act  of  1933  (“ Securities  Act”)  and  all  applicable  state
securities or blue sky laws and (iii) delivery by the transferee of a written statement to the Company making the representations and certifications as the Company may
reasonably  request  to  procure  an  exemption  from  Section  5  of  the  Securities Act.  Upon  any  such  registration  or  transfer,  a  new  warrant  to  purchase  Common  Stock  in
substantially the form of this Warrant (any such new warrant, a “ New Warrant”) evidencing the portion of this Warrant so transferred shall be issued to the transferee, and a
New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by
the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a Holder of a Warrant.

 
 
 
 
 
 
 
 
 
 
 
4.         Exercise and Duration of Warrants.

(a)         All or any part of this Warrant shall be exercisable by the registered Holder at any time and from time to time on or after the Trigger Date and
through and including 5:00 P.M. prevailing Pacific time on the Expiration Date. At 5:00 P.M., prevailing Pacific time, on the Expiration Date, the portion of this Warrant not
exercised prior thereto shall be and become void and of no value and this Warrant shall be terminated and no longer outstanding.

(b)         The Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached as Schedule 1 hereto (the “Exercise
Notice”), appropriately completed and duly signed, (ii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised (which
may take the form of a “cashless exercise” if so indicated in the Exercise Notice and if a “cashless exercise” may occur at such time pursuant to Section 10 below), and the
date such items are delivered to the Company (as determined in accordance with the notice provisions hereof) is an “Exercise Date.” The Holder shall not be required to
deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original
Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.

5.         Delivery of Warrant Shares. Upon exercise of this Warrant, the Company shall promptly issue or cause to be issued and cause to be delivered to or upon the
written order of the Holder and in such name or names as the Holder may designate a certificate for the Warrant Shares issuable upon such exercise, with an appropriate
restrictive legends. The Holder, or any Person permissibly so designated by the Holder to receive Warrant Shares, shall be deemed to have become the holder of record of
such Warrant Shares as of the Exercise Date.

6.         Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge
to the Holder for any issue or transfer tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses
shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the
registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder or an Affiliate thereof. The Holder shall be responsible for all other tax
liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7 .         Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution
for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of
such loss, theft or destruction (in such case) and, in each case, a customary and reasonable indemnity (which shall not include a surety bond), if requested. Applicants for a
New  Warrant  under  such  circumstances  shall  also  comply  with  such  other  reasonable  regulations  and  procedures  and  pay  such  other  reasonable  third-party  costs  as  the
Company may prescribe. If a New Warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the Company as a
condition precedent to the Company’s obligation to issue the New Warrant.

2

 
 
 
 
 
 
 
 
 
8 .         Reservation  of  Warrant  Shares.  The  Company  covenants  that  it  will  at  all  times  reserve  and  keep  available  out  of  the  aggregate  of  its  authorized  but
unissued  and  otherwise  unreserved  Common  Stock,  solely  for  the  purpose  of  enabling  it  to  issue  Warrant  Shares  upon  exercise  of  this  Warrant  as  herein  provided,  the
number of Warrant Shares which are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase
rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable and
deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid
and  nonassessable.  The  Company  will  take  all  such  action  as  may  be  necessary  to  assure  that  such  shares  of  Common  Stock  may  be  issued  as  provided  herein  without
violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common Shares may be
listed.

9 .         Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time

as set forth in this Section 9.

( a )         Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or
otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides its outstanding shares of Common Stock into a larger
number of shares, or (iii) combines its outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by
a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately before such event and the denominator of which shall be the
number  of  shares  of  Common  Stock  outstanding  immediately  after  such  event. Any  adjustment  made  pursuant  to  clause  (i)  of  this  paragraph  shall  become  effective
immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of
this paragraph shall become effective immediately after the effective date of such subdivision or combination.

( b )         Fundamental Transactions. If, at any time while this Warrant is outstanding (i) the Company effects any merger or consolidation of the Company
with or into another Person, in which the Company is not the survivor, (ii) the Company effects any sale of all or substantially all of its assets or a majority of its Common
Stock is acquired by a third party, in each case, in one or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company or another Person)
is completed pursuant to which all or substantially all of the holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property,
or (iv) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into
or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 9(a) above) (in any
such case, a “Fundamental Transaction”), then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities,
cash  or  property  as  it  would  have  been  entitled  to  receive  upon  the  occurrence  of  such  Fundamental  Transaction  if  it  had  been,  immediately  prior  to  such  Fundamental
Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein
(the “Alternate Consideration”). The provisions of this paragraph (b) shall similarly apply to subsequent transactions analogous to a Fundamental Transaction.

3

 
 
 
 
 
 
( c )         Number of Warrant Shares . Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) of this Section 9, the number of
Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise
Price  payable  hereunder  for  the  increased  or  decreased  number  of  Warrant  Shares  shall  be  the  same  as  the  aggregate  Exercise  Price  in  effect  immediately  prior  to  such
adjustment.

( d )         Calculations. All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The number of
shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the sale or issuance of any such
shares shall be considered an issue or sale of Common Stock.

(e)         Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will, at the written request of
the Holder, promptly compute such adjustment, in good faith, in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including
a  statement  of  the  adjusted  Exercise  Price  and  adjusted  number  or  type  of  Warrant  Shares  or  other  securities  issuable  upon  exercise  of  this  Warrant  (as  applicable),
describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will
promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent.

(f)         Notice of Corporate Events. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other distribution of cash, securities or
other  property  in  respect  of  its  Common  Stock,  including,  without  limitation,  any  granting  of  rights  or  warrants  to  subscribe  for  or  purchase  any  capital  stock  of  the
Company,  (ii)  authorizes  or  approves,  enters  into  any  agreement  contemplating  or  solicits  stockholder  approval  for  any  Fundamental  Transaction  or  (iii)  authorizes  the
voluntary dissolution, liquidation or winding up of the affairs of the Company, then, except if such notice and the contents thereof shall be deemed to constitute material
non-public information, the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction at least ten (10) Trading Days prior
to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the
Company will take all steps reasonably necessary in order to insure that the Holder is given the practical opportunity to exercise this Warrant prior to such time so as to
participate  in  or  vote  with  respect  to  such  transaction; provided, however,  that  the  failure  to  deliver  such  notice  or  any  defect  therein  shall  not  affect  the  validity  of  the
corporate action required to be described in such notice.

1 0 .         Payment  of  Exercise  Price.  The  Holder  shall  pay  the  Exercise  Price  in  immediately  available  funds; provided, however,  the  Holder  may,  in  its  sole
discretion, satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company shall issue to the Holder the number of Warrant Shares

market for such security, as reported by Bloomberg Financial Markets, or, if such exchange or trading market begins to operate on an extended hours basis and does not
designate  the  last  trade  price,  then  the  last  trade  price  of  such  security  prior  to  4:00:00  p.m.,  New  York  Time,  as  reported  by  Bloomberg  Financial  Markets,  or  if  the
foregoing  do  not  apply,  the  last  trade  price  of  such  security  in  the  over-the-counter  market  on  the  electronic  bulletin  board  for  such  security  as  reported  by  Bloomberg
Financial Markets, or, if no last trade price is reported for such security by Bloomberg Financial Markets, the Closing Sale Price of such security on such date shall be the
fair market value as mutually determined by the Company in its reasonable discretion.

For  purposes  of  Rule  144  promulgated  under  the  Securities  Act,  it  is  intended,  understood  and  acknowledged  that  the  Warrant  Shares  issued  in  a  cashless  exercise
transaction  shall  be  deemed  to  have  been  acquired  by  the  Holder,  and  the  holding  period  for  the  Warrant  Shares  shall  be  deemed  to  have  commenced,  on  the  date  this
Warrant was originally issued pursuant to the Consulting Agreement (provided that the Commission continues to take the position that such treatment is proper at the time of
such exercise).

1 1 .         No Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares which

would otherwise be issuable, the number of Warrant Shares to be issued shall be rounded up to the next whole number.

corporation or entity of the property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the Holder of this
Purchase Warrant shall have the right thereafter (until the expiration of the right of exercise of this Purchase Warrant) to receive upon the exercise hereof, for the same
aggregate  Exercise  Price  payable  hereunder  immediately  prior  to  such  event,  the  kind  and  amount  of  shares  of  stock  or  other  securities  or  property  (including  cash)
receivable upon such reclassification, reorganization, share reconstruction or amalgamation, or consolidation, or upon a dissolution following any such sale or transfer, by a
Holder of the number of Shares of the Company obtainable upon exercise of this Purchase Warrant immediately prior to such event; and if any reclassification also results in
a change in Shares covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this
Section 6.1.3 shall similarly apply to successive reclassifications, reorganizations, share reconstructions or amalgamations, or consolidations, sales or other transfers.

6.1.4         Changes in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this Section 6.1, and
Purchase  Warrants  issued  after  such  change  may  state  the  same  Exercise  Price  and  the  same  number  of  Shares  as  are  stated  in  the  Purchase  Warrants  initially  issued
pursuant to this Agreement. The acceptance by any Holder of the issuance of new Purchase Warrants reflecting a required or permissive  change  shall  not  be  deemed  to
waive any rights to an adjustment occurring after the Commencement Date or the computation thereof.

6.2         Substitute Purchase Warrant. In case of any consolidation of the Company with, or share reconstruction or amalgamation or merger of the Company with or
into,  another  corporation  (other  than  a  consolidation  or  share  reconstruction  or  amalgamation  or  merger  which  does  not  result  in  any  reclassification  or  change  of  the
outstanding Shares), the corporation formed by such consolidation or share reconstruction or amalgamation shall execute and deliver to the Holder a supplemental Purchase
Warrant providing that the holder of each Purchase Warrant then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase
Warrant) to receive, upon exercise of such Purchase Warrant, the kind and amount of shares of stock and other securities and property receivable upon such consolidation or
share reconstruction or amalgamation, by a holder of the number of Shares of the Company for which such Purchase Warrant might have been exercised immediately prior
to such consolidation, share reconstruction or amalgamation or merger, sale or transfer. Such supplemental Purchase Warrant shall provide for adjustments which shall be
identical to the adjustments provided for in this Section 6. The above provision of this Section shall similarly apply to successive consolidations or share reconstructions or
amalgamations or mergers.

6.3         Elimination of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Shares upon the exercise of the Purchase
Warrant, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests, it being the intent of the parties that all fractional interests shall be eliminated by
rounding any fraction up or down, as the case may be, to the nearest whole number of Shares or other securities, properties or rights.

7.         Reservation. The Company shall at all times reserve and keep available out of its authorized Shares, solely for the purpose of issuance upon exercise of the Purchase
Warrants,  such  number  of  Shares  or  other  securities,  properties  or  rights  as  shall  be  issuable  upon  the  exercise  thereof.  The  Company  covenants  and  agrees  that,  upon
exercise  of  the  Purchase  Warrants  and  payment  of  the  Exercise  Price  therefor,  in  accordance  with  the  terms  hereby,  all  Shares  and  other  securities  issuable  upon  such
exercise shall be duly and validly issued, fully paid and non- assessable and not subject to preemptive rights of any shareholder.

8.         Certain Notice Requirements.

8 . 1         Holder’s Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to receive notice as a
shareholder  for  the  election  of  directors  or  any  other  matter,  or  as  having  any  rights  whatsoever  as  a  shareholder  of  the  Company.  If,  however,  at  any  time  prior  to  the
expiration of the Purchase Warrants and their exercise, any of the events described in Section 8.2 shall occur, then, in one or more of said events, the Company shall deliver
to each Holder a copy of each notice relating to such events given to the other shareholders of the Company at the same time and in the same manner that such notice is

dividend  or  distribution  payable  otherwise  than  out  of  retained  earnings,  as  indicated  by  the  accounting  treatment  of  such  dividend  or  distribution  on  the  books  of  the
Company, or (ii) the Company shall offer to all the holders of its Shares any additional shares of capital stock of the Company or securities convertible into or exchangeable
for shares of capital stock of the Company, or any option, right or warrant to subscribe therefor.

8 . 3         Notice of Change in Exercise Price. The Company shall, promptly after an event requiring a change in the Exercise Price pursuant to Section 6 hereof, send

Fifty  and  No/lO0ths  Dollars  ($213,750)  ("Guaranteed  Minimum  Interest"),  Borrower  may  prepay  principal  on  the  Nate  without  fee.  To  the  extent  applicable,  Borrower
hereby expressly (i) waives any right it may have to prepay this Note in whole or in part, without fee or payment of Guaranteed Minimum Interest charge, upon acceleration
of the Maturity Date; and (ii) agrees that if a prepayment of any or all of this Note is made, following any acceleration of the Maturity Date by Lender on account of any
transfer or disposition prohibited or restricted herein or by the Loan Documents (defined below), Borrower shall be obligated to pay, concurrently therewith, the Guaranteed
Minimum Interest.

(d)    Loan Documents. The Note shall be secured by, among other things, a deed of trust ("Deed of Trust") encumbering the Property. This Agreement, the Note,

agreements and obligations of Borrower or the party which executes the same, enforceable in accordance with their respective terms.

SECTION  2.3  COMMERCIAL  LOAN.  Borrower  hereby  acknowledges  and  agrees  that  Lender  is  extending  the  Term  Loan  for  commercial  purposes  as  an

regulation,  nor  contravene  any  provision  of  any  articles  of  organization,  charter,  operating  agreement,  or  similar  organizational  and  operational  documents  applicable  to

year.

bound that requires the subordination in right of payment of any of Borrower's obligations subject to this Agreement to any other obligation of Borrower.

SECTION 2.9. PERMITS, FRANCHISES. Borrower possesses, and will hereafter possess, all permits, land use entitlements, consents, approvals, and licenses to

enable it to own the Property and put it to its current use in compliance with applicable law in all material respects.

Loan  is  in  violation  of  any  Legal  Requirement.  No  Borrower  nor  any  constituent  member  of  Borrower  has  been  previously  indicted  for  or  convicted  of  any  Patriot Act
Offense, or is currently under investigation by any Governmental Authority with respect to any alleged Patriot Act Offense.

SECTION  2.17.  ANTI-MONEY  LAUNDERING.  None  of  the  funds  of  Borrower,  Member  or  Guarantor,  as  applicable,  that  are  used  to  consummate  this
transaction or to operate the Property are derived from or are the proceeds of any unlawful activity, with the result that the investment in Borrower, Member or Guarantor, as
applicable (whether directly or indirectly), is prohibited by law or the Loan is in violation of law or may cause any of the Property to be subject to forfeiture or seizure.
Borrower  has  ascertained  the  identity  of  all  persons  and  entities  who  have  provided  funds  to  capitalize  Borrower  and  has  conducted  verification  procedures  which  are
sufficient to establish the identity and source of such funds.

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

without limitation all K-1 statements, each of which shall be signed and certified by Borrower to be true and complete copies of such returns.

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.

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.

6

 
 
 
 
 
 
 
 
 
 
 
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.

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.

7

 
 
 
 
 
 
 
 
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

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.

8

 
 
 
 
 
 
 
 
 
 
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

its assets or perform its obligations under the Loan Documents.

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

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.

SECTION 7.14 COMMISSION AND BROKERAGE FEE. Borrower, at its sole cost and expense, has authorized Alpen Mortgage, Inc. 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.

SECTION7.15  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.

and  conditions  in  the  operative  Employee  Handbook  executed  by  Employee  and  all  Company  policies,  procedures,  and  other  agreements  now  in  existence  or  hereafter

Company during the tenure of his employment.

3.       COMPENSATION.

3.1    Salary. The Employee will be paid an annual salary of $491,400, less state and federal withholding and authorized deductions (“Salary”),  on  a  bi-
weekly basis (or according to the Company’s customary payroll practices in effect at the time). The Employee’s Salary shall be reviewed at least annually by the Board and
the Board may, but shall not be required to, increase the Employee’s Salary. However, the Employee’s Salary may not be decreased without the Employee’s consent, other

3.2      Annual Performance-Based Bonuses.

3.2.1        Except  as  otherwise  stated  herein,  Employee  shall  be  eligible  to  receive  annual  performance-based  short-term  incentive  bonuses  (each  a
“STIP Bonus”)  of  up  to  100%  of  his  then-current  Salary,  based  upon  achievement  of  specific  performance  milestones  (“Milestones”)  established  by  the  Compensation
Committee of the Board (“Committee”) in advance and at its discretion. The STIP Bonus shall be paid, at the Company’s option, in cash or restricted stock units (“RSUs”)
under the Plan.

3.2.2        Except  as  otherwise  stated  herein,  Employee  shall  be  eligible  to  receive  annual  performance-based  long-term  incentive  bonuses  (each  a

Bonus shall be paid in RSUs under the Plan.

2 of 11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
3.2.3    Each RSU shall entitle the Employee to receive one (1) share of the Company’s $0.001 par value common stock (“Common Stock”) based on
satisfaction of the Milestones. Upon the Committee’s determination of the satisfaction of the relevant Milestones for any annual STIP or LTIP Bonus, and the amount of
STIP Bonus and LTIP Bonus earned, the Committee shall cause the Company to provide the Employee with an award of cash or RSUs, or a combination of both, in the case
of the STIP Bonus and RSUs in the case of the LTIP Bonus. The number of RSUs to be awarded to the Employee shall be the dollar value of the STIP Bonus or LTIP
Bomus to be paid in RSUs divided by the Fair Market Value (as such term is defined in the Plan) of one share of Common Stock as of the award date.

3.3     Benefits. Employee shall be entitled to the insurance and employee benefits set forth in the Employee Handbook and such other benefits that are made

incurred in connection with the performance of his duties hereunder in accordance with the Company's expense reimbursement policies and procedures.

3.5          Withholding.  The  Company  has  the  right  to  withhold  from  any  amount  payable  hereunder  any  Federal,  state,  and  local  taxes  in  order  for  the
Company to satisfy any withholding tax obligation it may have under any applicable law or regulation. Further, the Employee shall make arrangements satisfactory to the
Company to pay to the Company any federal, state or local income taxes required to be withheld with respect to any Incentive Awards. If the Employee shall fail to make
such tax payments as are required, the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind otherwise due to the Employee
any federal, state or local taxes of any kind required by law to be withheld with respect to any such Incentive Award.

3.6     Incentive Compensation Clawback. Notwithstanding any other provisions in this Agreement to the contrary, any (a) incentive-based compensation
paid to Employee for meeting a financial reporting measure that is based on or derived from financial information or (b) other compensation paid to Employee under this
Agreement  or  any  other  agreement  or  arrangement  with  the  Company  which  is  subject  to  recovery  under  any  law,  government  regulation,  or  stock  exchange  listing
requirement, will be subject to such deductions and clawback as may be required to be made pursuant to such law, government regulation, or NASDAQ listing requirement
(or any policy adopted by the Company pursuant to any such law, government regulation or NASDAQ listing requirement).

3.7    Section 409A. It is intended that any amounts payable under this Agreement (including Section 3 and Section 5.4) and the Company’s and Employee’s
exercise of authority or discretion hereunder shall be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended (“Code”) , including
the Treasury Regulations and other published guidance relating thereto (collectively, “Code Section 409A”), so as not to subject Employee to the payment of any interest or
additional  tax  imposed  under  Code  Section  409A.  This Agreement  shall  be  interpreted  on  a  basis  consistent  with  such  intent.  If  any  payments  or  benefits  provided  to
Employee by the Company, either per this Agreement or otherwise, are non-qualified deferred compensation subject to, and not exempt from, Code Section 409A (“ Subject
Payments”), the following provisions shall apply to such payments and/or benefits:

3.7.1        For  payments  and  benefits  triggered  by  termination  of  employment,  reference  to  Employee’s  “termination  of  employment”  (and  corollary
terms) with the Company shall be construed to refer to Employee’s “separation from service” from the Company (with such phrase determined under Treas. Reg. Section
1.409A-1(h), as uniformly applied by the Company) in tandem with the termination of his employment with the Company.

3.7.2    If Employee is deemed on the date of his “separation from service” to be a “specified employee” (within the meaning of Treas. Reg. Section
1.409A-1(i)), then with regard to any payment that is required to be delayed pursuant to Code Section 409A(a)(2)(B) (the “Delayed Payments”), such payment shall not be
made prior to the earlier of (i) the first day of the seventh month following the date of his “separation from service” and (ii) the date of his death. The Delayed Payments
shall be paid to Employee in a lump sum promptly following the date set forth in the preceding sentence. Any payments other than the Delayed Payments shall be paid in
accordance with the normal payment dates specified herein. In no case will the delay of any of the Delayed Payments by the Company constitute a breach of the Company’s
obligations to Employee.

distinct payments.

3.7.3    Employee’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and

the specified period shall be within the sole discretion of the Company.

3.7.4    Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within

3.7.5        If  the  60  day  period  following  Employee’s  “separation  from  service”  begins  in  one  calendar  year  and  ends  in  a  second  calendar  year  (a
“Crossover 60-Day Period”), then any severance payments subject to Code Section 409A that would otherwise occur during the portion of the Crossover 60-Day Period that
falls  within  the  first  year  will  be  delayed  and  paid  in  a  lump-sum  upon  the  later  of  (i)  January  1  of  the  calendar  year  following  the  calendar  year  in  which  Employee’s
“separation from service” occurs, and (ii) the date when the payment of severance payments would otherwise begin hereunder.

amount unless otherwise permitted by Code Section 409A.

3.7.6    Notwithstanding any other provision of this Agreement to the contrary, in no event shall any Subject Payment be subject to offset by any other

4 of 11

 
 
 
 
 
 
 
 
 
3.7.7    To the extent that any reimbursement or in-kind benefits are Subject Payments: (i) the amount eligible for reimbursement or in-kind benefit in
one calendar year may not affect the amount eligible for reimbursement or in-kind benefit in any other calendar year (except that a plan providing medical or health benefits
may impose a generally applicable limit on the amount that may be reimbursed or paid), (ii) the right to reimbursement or an in-kind benefit is not subject to liquidation or
exchange for another benefit, and (iii) subject to any shorter time periods provided herein, any such reimbursement of an expense or in-kind benefit must be made on or
before the last day of the calendar year following the calendar year in which the expense was incurred.

negotiate in good faith to amend this Agreement in a manner that preserves the original intent of the parties hereto to the extent reasonably possible.

3.7.8    If an amendment of this Agreement is necessary in order for it to comply with Code Section 409A, Employee and the Company agree to

3.8     Limitation on Payments. In the event that the benefits provided for in this Agreement or otherwise payable to Employee (i) constitute “parachute
payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”),  then
Employee’s  benefits  under  this Agreement  shall  be  either  (A)  delivered,  subject  to  any  applicable  tax  or  other  withholdings,  in  full,  or  (B)  delivered,  subject  to  any
applicable tax or other withholdings, to such lesser extent as would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts,
taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by Employee, on an after-tax basis, of the greatest amount of
benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. Unless the Company and Employee otherwise agree in
writing, any determination required under this Section shall be made in writing by an independent public accountant chosen by the Company (the “Accountant”),  whose
determination  shall  be  conclusive  and  binding  upon  Employee  and  the  Company  for  all  purposes.  For  purposes  of  making  the  calculations  required  by  this  Section,  the
Accountant  may  make  reasonable  assumptions  and  approximations  concerning  applicable  taxes  and  may  rely  on  reasonable,  good  faith  interpretations  concerning  the
application of Section 280G and 4999 of the Code. The Company and Employee shall furnish to the Accountant such information and documents as the Accountant may
reasonably  request  in  order  to  make  a  determination  under  this  Section.  The  Company  shall  bear  all  costs  the Accountant  may  reasonably  incur  in  connection  with  any
calculations contemplated by this Section.

4.      PROTECTION/NON-DISCLOSURE OF COMPANY CONFIDENTIAL INFORMATION AND TRADE SECRETS. Employee acknowledges having
entered  into  that  certain  Confidential  Information,  Non-Disclosure,  and  Trade  Secrets  Agreement  attached  hereto  as Exhibit  A  to  this  Agreement  (“Confidentiality
Agreement”) dated 7/10/2023 with the Company. Employee covenants and agrees to strictly comply with the terms of Confidentiality Agreement during the term of this
Agreement and following the termination of his employment with the Company, as provided for in the Confidentiality Agreement.

5.       TERMINATION. In accordance with Section 1, either party may terminate the employment relationship and this Agreement at any time and for any reason;
provided  that,  unless  otherwise  provided  herein,  either  party  shall  be  required  to  give  the  other  party  at  least  30  days  advance  written  notice  of  any  termination  of  the
Employee’s employment. Notwithstanding the foregoing, the Company shall entitled to terminate the Agreement for Cause immediately upon delivery of written notice.

5 of 11

 
 
 
 
 
 
 
5.1    Final Pay and Expenses. Upon the termination of employment, the Company shall pay Employee all Salary and unreimbursed expenses due through

the date on which employment terminates.

5.2        Resignation  of  all  Other  Positions. Upon  termination  of  employment,  Employee  shall  be  deemed  to  have  resigned  from  all  positions  that  the

Employee holds as an officer, employee, or member of the Board (or a committee thereof) of the Company or any of its affiliates.

5.3    Return of Property. Upon termination of employment, Employee shall return all Company’s property such as cell phones, laptops, or other tangible
and intangible property including, without limitation, customer lists, manuals, contract forms, documents or any other tangible or intangible documents or information used
by the Company in the Employee’s possession at the time of termination, in a manner consistent with Company policy.

5.4     Severance on Termination

5.4.1        Absent  a  Change  in  Control.  In  addition  to  payments  under  Section  5.1  and  subject  to Section  5.4.3,  if  Employee’s  employment  is
terminated, either (i) by the Company (other than for Cause, Disability, or death), or (ii) by the Employee for Good Reason, then the Employee (or his estate or personal
representative),  shall  be  entitled  to  (a)  equal  installment  payments  of  Employee’s  then-current  Salary,  less  all  federal  and  state  withholding,  for  a  period  of  24  months,
payable in accordance with the Company's normal payroll practices; (b) the Company’s payment or reimbursement of Employee’s Benefits in effect at the time of the Notice
of  Termination  for  a  period  of  24  months;  and  (c)  a  pro-rata  percentage  of  Employee’s  STIP  Bonus  and  LTIP  Bonus,  assuming  the  satisfaction  of  all  Milestones,  as

employed, and payable in accordance with the Company’s normal practice for the payment of such bonuses.

5.4.2        Following  a  Change  in  Control. In  addition  to  payments  under  Section  5.1  and  subject  to Section 5.4.3,  if  Employee’s  employment  is
terminated during the Protected Period following a Change in Control, either (i) by the Company (other than for Cause, Disability or death), or (ii) by the Employee for Good
Reason:

5.4.2.1        the  Employee  (or  his  estate  or  personal  representative):  shall  be  entitled  to  (a)  equal  installment  payments  of  Employee’s  then-current
Salary, less all federal and state withholding, for a period of 24 months, payable in accordance with the Company's normal payroll practices; (b) the Company’s payment or
reimbursement of Employee’s Benefits in effect at the time of the Notice of Termination for a period of 24 months; and (c) Employee’s entire STIP Bonus and LTIP Bonus,

accordance with the Company’s normal practice for the payment of such bonuses.

6 of 11

 
 
 
 
 
 
 
 
 
5.4.2.2    all outstanding and unvested Incentive Awards held by Employee as of the Date of Termnation shall vest in full; provided however, if an
outstanding Incentive Award is subject to Code Section 409A, the acceleration of vesting will not change the time or form of payment in a manner that would violate Code
Section 409A; if an outstanding Incentive Award is exempt from Code Section 409A, the Incentive Award will be administered in a manner that retains such exemption or
otherwise complies with Code Section 409A. Any outstanding Incentive Awards held by the Employee as of the Date of Termination shall remain exercisable and subject to
termination as provided in the Plan.

5.4.3    Conditions to Receiving Severance. The receipt of any severance pursuant to this Section is subject to: (a) Employee timely signing and not

Company during the tenure of his employment.

3.        COMPENSATION.

3.1    Salary. The Employee will be paid an annual salary of $360,500.00, less state and federal withholding and authorized deductions (“Salary”), on a bi-
weekly basis (or according to the Company’s customary payroll practices in effect at the time). The Employee’s Salary shall be reviewed at least annually by the Board and
the Board may, but shall not be required to, increase the Employee’s Salary. However, the Employee’s Salary may not be decreased without the Employee’s consent, other
than as part of an across-the-board salary reduction that applies in the same manner to all senior executives.

3.2       Annual Performance-Based Bonuses.

3.2.1        Except  as  otherwise  stated  herein,  Employee  shall  be  eligible  to  receive  annual  performance-based  short-term  incentive  bonuses  (each  a
“STIP Bonus”)  of  up  to  75%  of  his  then-current  Salary,  based  upon  achievement  of  specific  performance  milestones  (“Milestones”)  established  by  the  Compensation
Committee of the Board (“Committee”) in advance and at its discretion. The STIP Bonus shall be paid, at the Company’s option, in cash or restricted stock units (“RSUs”)

Bonus shall be paid in RSUs under the Plan.

2 of 11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
3.2.3    Each RSU shall entitle the Employee to receive one (1) share of the Company’s $0.001 par value common stock (“Common Stock”) based on
satisfaction of the Milestones. Upon the Committee’s determination of the satisfaction of the relevant Milestones for any annual STIP or LTIP Bonus, and the amount of
STIP Bonus and LTIP Bonus earned, the Committee shall cause the Company to provide the Employee with an award of cash or RSUs, or a combination of both, in the case
of the STIP Bonus and RSUs in the case of the LTIP Bonus. The number of RSUs to be awarded to the Employee shall be the dollar value of the STIP Bonus or LTIP
Bomus to be paid in RSUs divided by the Fair Market Value (as such term is defined in the Plan) of one share of Common Stock as of the award date.

3.3    Benefits. Employee shall be entitled to the insurance and employee benefits set forth in the Employee Handbook and such other benefits that are made

incurred in connection with the performance of his duties hereunder in accordance with the Company's expense reimbursement policies and procedures.

3.5    Withholding. The Company has the right to withhold from any amount payable hereunder any Federal, state, and local taxes in order for the Company
to satisfy any withholding tax obligation it may have under any applicable law or regulation. Further, the Employee shall make arrangements satisfactory to the Company to
pay  to  the  Company  any  federal,  state  or  local  income  taxes  required  to  be  withheld  with  respect  to  any  Incentive Awards.  If  the  Employee  shall  fail  to  make  such  tax
payments as are required, the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind otherwise due to the Employee any
federal, state or local taxes of any kind required by law to be withheld with respect to any such Incentive Award.

3.6    Incentive Compensation Clawback. Notwithstanding any other provisions in this Agreement to the contrary, any (a) incentive-based compensation
paid to Employee for meeting a financial reporting measure that is based on or derived from financial information or (b) other compensation paid to Employee under this
Agreement  or  any  other  agreement  or  arrangement  with  the  Company  which  is  subject  to  recovery  under  any  law,  government  regulation,  or  stock  exchange  listing
requirement, will be subject to such deductions and clawback as may be required to be made pursuant to such law, government regulation, or NASDAQ listing requirement
(or any policy adopted by the Company pursuant to any such law, government regulation or NASDAQ listing requirement).

3.7    Section 409A. It is intended that any amounts payable under this Agreement (including Section 3 and Section 5.4) and the Company’s and Employee’s
exercise of authority or discretion hereunder shall be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended (“Code”) , including
the Treasury Regulations and other published guidance relating thereto (collectively, “Code Section 409A”), so as not to subject Employee to the payment of any interest or
additional  tax  imposed  under  Code  Section  409A.  This Agreement  shall  be  interpreted  on  a  basis  consistent  with  such  intent.  If  any  payments  or  benefits  provided  to
Employee by the Company, either per this Agreement or otherwise, are non-qualified deferred compensation subject to, and not exempt from, Code Section 409A (“ Subject
Payments”), the following provisions shall apply to such payments and/or benefits:

3.7.1        For  payments  and  benefits  triggered  by  termination  of  employment,  reference  to  Employee’s  “termination  of  employment”  (and  corollary
terms) with the Company shall be construed to refer to Employee’s “separation from service” from the Company (with such phrase determined under Treas. Reg. Section
1.409A-1(h), as uniformly applied by the Company) in tandem with the termination of his employment with the Company.

3.7.2    If Employee is deemed on the date of his “separation from service” to be a “specified employee” (within the meaning of Treas. Reg. Section
1.409A-1(i)), then with regard to any payment that is required to be delayed pursuant to Code Section 409A(a)(2)(B) (the “Delayed Payments”), such payment shall not be
made prior to the earlier of (i) the first day of the seventh month following the date of his “separation from service” and (ii) the date of his death. The Delayed Payments
shall be paid to Employee in a lump sum promptly following the date set forth in the preceding sentence. Any payments other than the Delayed Payments shall be paid in
accordance with the normal payment dates specified herein. In no case will the delay of any of the Delayed Payments by the Company constitute a breach of the Company’s
obligations to Employee.

distinct payments.

3.7.3    Employee’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and

the specified period shall be within the sole discretion of the Company.

3.7.4    Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within

3.7.5        If  the  60  day  period  following  Employee’s  “separation  from  service”  begins  in  one  calendar  year  and  ends  in  a  second  calendar  year  (a
“Crossover 60-Day Period”), then any severance payments subject to Code Section 409A that would otherwise occur during the portion of the Crossover 60-Day Period that
falls  within  the  first  year  will  be  delayed  and  paid  in  a  lump-sum  upon  the  later  of  (i)  January  1  of  the  calendar  year  following  the  calendar  year  in  which  Employee’s
“separation from service” occurs, and (ii) the date when the payment of severance payments would otherwise begin hereunder.

amount unless otherwise permitted by Code Section 409A.

3.7.6    Notwithstanding any other provision of this Agreement to the contrary, in no event shall any Subject Payment be subject to offset by any other

3.7.7    To the extent that any reimbursement or in-kind benefits are Subject Payments: (i) the amount eligible for reimbursement or in-kind benefit in
one calendar year may not affect the amount eligible for reimbursement or in-kind benefit in any other calendar year (except that a plan providing medical or health benefits
may impose a generally applicable limit on the amount that may be reimbursed or paid), (ii) the right to reimbursement or an in-kind benefit is not subject to liquidation or
exchange for another benefit, and (iii) subject to any shorter time periods provided herein, any such reimbursement of an expense or in-kind benefit must be made on or
before the last day of the calendar year following the calendar year in which the expense was incurred.

negotiate in good faith to amend this Agreement in a manner that preserves the original intent of the parties hereto to the extent reasonably possible.

3.7.8    If an amendment of this Agreement is necessary in order for it to comply with Code Section 409A, Employee and the Company agree to

3.8    Limitation on Payments. In the event that the benefits provided for in this Agreement or otherwise payable to Employee (i) constitute “parachute
payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”),  then
Employee’s  benefits  under  this Agreement  shall  be  either  (A)  delivered,  subject  to  any  applicable  tax  or  other  withholdings,  in  full,  or  (B)  delivered,  subject  to  any
applicable tax or other withholdings, to such lesser extent as would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts,
taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by Employee, on an after-tax basis, of the greatest amount of
benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. Unless the Company and Employee otherwise agree in
writing, any determination required under this Section shall be made in writing by an independent public accountant chosen by the Company (the “Accountant”),  whose
determination  shall  be  conclusive  and  binding  upon  Employee  and  the  Company  for  all  purposes.  For  purposes  of  making  the  calculations  required  by  this  Section,  the
Accountant  may  make  reasonable  assumptions  and  approximations  concerning  applicable  taxes  and  may  rely  on  reasonable,  good  faith  interpretations  concerning  the
application of Section 280G and 4999 of the Code. The Company and Employee shall furnish to the Accountant such information and documents as the Accountant may
reasonably  request  in  order  to  make  a  determination  under  this  Section.  The  Company  shall  bear  all  costs  the Accountant  may  reasonably  incur  in  connection  with  any
calculations contemplated by this Section.

4.     PROTECTION/NON-DISCLOSURE OF COMPANY CONFIDENTIAL INFORMATION AND TRADE SECRETS. Employee acknowledges having
entered  into  that  certain  Confidential  Information,  Non-Disclosure,  and  Trade  Secrets  Agreement  attached  hereto  as Exhibit  A  to  this  Agreement  (“Confidentiality
Agreement”) dated February 18, 2020 with the Company. Employee covenants and agrees to strictly comply with the terms of Confidentiality Agreement during the term of
this Agreement and following the termination of his employment with the Company, as provided for in the Confidentiality Agreement.

5.      TERMINATION. In accordance with Section 1, either party may terminate the employment relationship and this Agreement at any time and for any reason;
provided  that,  unless  otherwise  provided  herein,  either  party  shall  be  required  to  give  the  other  party  at  least  30  days  advance  written  notice  of  any  termination  of  the
Employee’s employment. Notwithstanding the foregoing, the Company shall entitled to terminate the Agreement for Cause immediately upon delivery of written notice.

the date on which employment terminates.

5.2        Resignation  of  all  Other  Positions. Upon  termination  of  employment,  Employee  shall  be  deemed  to  have  resigned  from  all  positions  that  the

Employee holds as an officer, employee, or member of the Board (or a committee thereof) of the Company or any of its affiliates.

5.3    Return of Property. Upon termination of employment, Employee shall return all Company’s property such as cell phones, laptops, or other tangible
and intangible property including, without limitation, customer lists, manuals, contract forms, documents or any other tangible or intangible documents or information used
by the Company in the Employee’s possession at the time of termination, in a manner consistent with Company policy.

5.4      Severance on Termination

5.4.1        Absent  a  Change  in  Control.  In  addition  to  payments  under  Section  5.1  and  subject  to Section  5.4.3,  if  Employee’s  employment  is
terminated, either (i) by the Company (other than for Cause, Disability, or death), or (ii) by the Employee for Good Reason, then the Employee (or his estate or personal
representative),  shall  be  entitled  to  (a)  equal  installment  payments  of  Employee’s  then-current  Salary,  less  all  federal  and  state  withholding,  for  a  period  of  18  months,
payable in accordance with the Company's normal payroll practices; (b) the Company’s payment or reimbursement of Employee’s Benefits in effect at the time of the Notice
of  Termination  for  a  period  of  18  months;  and  (c)  a  pro-rata  percentage  of  Employee’s  STIP  Bonus  and  LTIP  Bonus,  assuming  the  satisfaction  of  all  Milestones,  as

and  conditions  in  the  operative  Employee  Handbook  executed  by  Employee  and  all  Company  policies,  procedures,  and  other  agreements  now  in  existence  or  hereafter

sensitive information affecting such securities), in whatever jurisdiction, and to observe and comply with all laws and regulations of any stock exchange, market or dealing
system in which such dealings take place; and

(f)        Refrain  from  directly  or  indirectly  render  any  services  of  a  business,  commercial,  or  professional  nature  to  any  other  person  or  organization,

Company during the tenure of his employment.

3.       COMPENSATION.

3.1     Salary. The Employee will be paid an annual salary of $273,000.00, less state and federal withholding and authorized deductions (“Salary”), on a bi-
weekly basis (or according to the Company’s customary payroll practices in effect at the time). The Employee’s Salary shall be reviewed at least annually by the Board and
the Board may, but shall not be required to, increase the Employee’s Salary. However, the Employee’s Salary may not be decreased without the Employee’s consent, other
than as part of an across-the-board salary reduction that applies in the same manner to all senior executives.

3.2       Annual Performance-Based Bonuses.

3.2.1        Except  as  otherwise  stated  herein,  Employee  shall  be  eligible  to  receive  annual  performance-based  short-term  incentive  bonuses  (each  a
“STIP Bonus”)  of  up  to  50%  of  his  then-current  Salary,  based  upon  achievement  of  specific  performance  milestones  (“Milestones”)  established  by  the  Compensation
Committee of the Board (“Committee”) in advance and at its discretion. The STIP Bonus shall be paid, at the Company’s option, in cash or restricted stock units (“RSUs”)
under the Plan.

3.2.2        Except  as  otherwise  stated  herein,  Employee  shall  be  eligible  to  receive  annual  performance-based  long-term  incentive  bonuses  (each  a
“LTIP Bonus”) of up to 100% of his then-current Salary, based upon achievement of Milestones established by the Committee in advance and at its discretion. The LTIP
Bonus shall be paid in RSUs under the Plan.

2 of 11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
3.2.3    Each RSU shall entitle the Employee to receive one (1) share of the Company’s $0.001 par value common stock (“Common Stock”) based on
satisfaction of the Milestones. Upon the Committee’s determination of the satisfaction of the relevant Milestones for any annual STIP or LTIP Bonus, and the amount of
STIP Bonus and LTIP Bonus earned, the Committee shall cause the Company to provide the Employee with an award of cash or RSUs, or a combination of both, in the case
of the STIP Bonus and RSUs in the case of the LTIP Bonus. The number of RSUs to be awarded to the Employee shall be the dollar value of the STIP Bonus or LTIP
Bomus to be paid in RSUs divided by the Fair Market Value (as such term is defined in the Plan) of one share of Common Stock as of the award date.

3.3    Benefits. Employee shall be entitled to the insurance and employee benefits set forth in the Employee Handbook and such other benefits that are made
available generally to senior management of the Company (“Benefits”). The Company does not warrant that it will continue to offer the same or similar medical insurance

3.4          Expenses. The Employee is entitled to reimbursement for all reasonable and necessary out-of-pocket business, entertainment, and travel expenses

incurred in connection with the performance of his duties hereunder in accordance with the Company's expense reimbursement policies and procedures.

3.5    Withholding. The Company has the right to withhold from any amount payable hereunder any Federal, state, and local taxes in order for the Company
to satisfy any withholding tax obligation it may have under any applicable law or regulation. Further, the Employee shall make arrangements satisfactory to the Company to
pay  to  the  Company  any  federal,  state  or  local  income  taxes  required  to  be  withheld  with  respect  to  any  Incentive Awards.  If  the  Employee  shall  fail  to  make  such  tax
payments as are required, the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind otherwise due to the Employee any
federal, state or local taxes of any kind required by law to be withheld with respect to any such Incentive Award.

3.6    Incentive Compensation Clawback. Notwithstanding any other provisions in this Agreement to the contrary, any (a) incentive-based compensation
paid to Employee for meeting a financial reporting measure that is based on or derived from financial information or (b) other compensation paid to Employee under this
Agreement  or  any  other  agreement  or  arrangement  with  the  Company  which  is  subject  to  recovery  under  any  law,  government  regulation,  or  stock  exchange  listing
requirement, will be subject to such deductions and clawback as may be required to be made pursuant to such law, government regulation, or NASDAQ listing requirement
(or any policy adopted by the Company pursuant to any such law, government regulation or NASDAQ listing requirement).

3 of 11

 
 
 
 
 
 
3.7    Section 409A. It is intended that any amounts payable under this Agreement (including Section 3 and Section 5.4) and the Company’s and Employee’s
exercise of authority or discretion hereunder shall be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended (“Code”) , including
the Treasury Regulations and other published guidance relating thereto (collectively, “Code Section 409A”), so as not to subject Employee to the payment of any interest or
additional  tax  imposed  under  Code  Section  409A.  This Agreement  shall  be  interpreted  on  a  basis  consistent  with  such  intent.  If  any  payments  or  benefits  provided  to
Employee by the Company, either per this Agreement or otherwise, are non-qualified deferred compensation subject to, and not exempt from, Code Section 409A (“ Subject
Payments”), the following provisions shall apply to such payments and/or benefits:

3.7.1        For  payments  and  benefits  triggered  by  termination  of  employment,  reference  to  Employee’s  “termination  of  employment”  (and  corollary
terms) with the Company shall be construed to refer to Employee’s “separation from service” from the Company (with such phrase determined under Treas. Reg. Section
1.409A-1(h), as uniformly applied by the Company) in tandem with the termination of his employment with the Company.

3.7.2    If Employee is deemed on the date of his “separation from service” to be a “specified employee” (within the meaning of Treas. Reg. Section
1.409A-1(i)), then with regard to any payment that is required to be delayed pursuant to Code Section 409A(a)(2)(B) (the “Delayed Payments”), such payment shall not be
made prior to the earlier of (i) the first day of the seventh month following the date of his “separation from service” and (ii) the date of his death. The Delayed Payments
shall be paid to Employee in a lump sum promptly following the date set forth in the preceding sentence. Any payments other than the Delayed Payments shall be paid in
accordance with the normal payment dates specified herein. In no case will the delay of any of the Delayed Payments by the Company constitute a breach of the Company’s
obligations to Employee.

distinct payments.

3.7.3    Employee’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and

the specified period shall be within the sole discretion of the Company.

3.7.4    Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within

3.7.5        If  the  60  day  period  following  Employee’s  “separation  from  service”  begins  in  one  calendar  year  and  ends  in  a  second  calendar  year  (a
“Crossover 60-Day Period”), then any severance payments subject to Code Section 409A that would otherwise occur during the portion of the Crossover 60-Day Period that
falls  within  the  first  year  will  be  delayed  and  paid  in  a  lump-sum  upon  the  later  of  (i)  January  1  of  the  calendar  year  following  the  calendar  year  in  which  Employee’s
“separation from service” occurs, and (ii) the date when the payment of severance payments would otherwise begin hereunder.

amount unless otherwise permitted by Code Section 409A.

3.7.6    Notwithstanding any other provision of this Agreement to the contrary, in no event shall any Subject Payment be subject to offset by any other

4 of 11

 
 
 
 
 
 
 
 
 
 
3.7.7    To the extent that any reimbursement or in-kind benefits are Subject Payments: (i) the amount eligible for reimbursement or in-kind benefit in
one calendar year may not affect the amount eligible for reimbursement or in-kind benefit in any other calendar year (except that a plan providing medical or health benefits
may impose a generally applicable limit on the amount that may be reimbursed or paid), (ii) the right to reimbursement or an in-kind benefit is not subject to liquidation or
exchange for another benefit, and (iii) subject to any shorter time periods provided herein, any such reimbursement of an expense or in-kind benefit must be made on or
before the last day of the calendar year following the calendar year in which the expense was incurred.

negotiate in good faith to amend this Agreement in a manner that preserves the original intent of the parties hereto to the extent reasonably possible.

3.7.8    If an amendment of this Agreement is necessary in order for it to comply with Code Section 409A, Employee and the Company agree to

3.8    Limitation on Payments. In the event that the benefits provided for in this Agreement or otherwise payable to Employee (i) constitute “parachute
payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”),  then
Employee’s  benefits  under  this Agreement  shall  be  either  (A)  delivered,  subject  to  any  applicable  tax  or  other  withholdings,  in  full,  or  (B)  delivered,  subject  to  any
applicable tax or other withholdings, to such lesser extent as would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts,
taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by Employee, on an after-tax basis, of the greatest amount of
benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. Unless the Company and Employee otherwise agree in
writing, any determination required under this Section shall be made in writing by an independent public accountant chosen by the Company (the “Accountant”),  whose
determination  shall  be  conclusive  and  binding  upon  Employee  and  the  Company  for  all  purposes.  For  purposes  of  making  the  calculations  required  by  this  Section,  the
Accountant  may  make  reasonable  assumptions  and  approximations  concerning  applicable  taxes  and  may  rely  on  reasonable,  good  faith  interpretations  concerning  the
application of Section 280G and 4999 of the Code. The Company and Employee shall furnish to the Accountant such information and documents as the Accountant may
reasonably  request  in  order  to  make  a  determination  under  this  Section.  The  Company  shall  bear  all  costs  the Accountant  may  reasonably  incur  in  connection  with  any
calculations contemplated by this Section.

4.    PROTECTION/NON-DISCLOSURE  OF  COMPANY  CONFIDENTIAL  INFORMATION AND  TRADE  SECRETS. Employee  acknowledges  having
entered  into  that  certain  Confidential  Information,  Non-Disclosure,  and  Trade  Secrets  Agreement  attached  hereto  as Exhibit  A  to  this  Agreement  (“Confidentiality
Agreement”) dated March 4, 2020 with the Company. Employee covenants and agrees to strictly comply with the terms of Confidentiality Agreement during the term of this
Agreement and following the termination of his employment with the Company, as provided for in the Confidentiality Agreement.

5.       TERMINATION. In accordance with Section 1, either party may terminate the employment relationship and this Agreement at any time and for any reason;
provided  that,  unless  otherwise  provided  herein,  either  party  shall  be  required  to  give  the  other  party  at  least  30  days  advance  written  notice  of  any  termination  of  the
Employee’s employment. Notwithstanding the foregoing, the Company shall entitled to terminate the Agreement for Cause immediately upon delivery of written notice.

5 of 11

 
 
 
 
 
 
 
5.1    Final Pay and Expenses. Upon the termination of employment, the Company shall pay Employee all Salary and unreimbursed expenses due through

the date on which employment terminates.

5.2        Resignation  of  all  Other  Positions. Upon  termination  of  employment,  Employee  shall  be  deemed  to  have  resigned  from  all  positions  that  the

Employee holds as an officer, employee, or member of the Board (or a committee thereof) of the Company or any of its affiliates.

5.3    Return of Property. Upon termination of employment, Employee shall return all Company’s property such as cell phones, laptops, or other tangible
and intangible property including, without limitation, customer lists, manuals, contract forms, documents or any other tangible or intangible documents or information used
by the Company in the Employee’s possession at the time of termination, in a manner consistent with Company policy.

5.4     Severance on Termination

5.4.1        Absent  a  Change  in  Control.  In  addition  to  payments  under  Section  5.1  and  subject  to Section  5.4.3,  if  Employee’s  employment  is

Company during the tenure of his employment.

3.       COMPENSATION.

3.1    Salary. The Employee will be paid an annual salary of $325,376.00, less state and federal withholding and authorized deductions (“Salary”), on a bi-
weekly basis (or according to the Company’s customary payroll practices in effect at the time). The Employee’s Salary shall be reviewed at least annually by the Board and

3.2      Annual Performance-Based Bonuses.

3.2.1        Except  as  otherwise  stated  herein,  Employee  shall  be  eligible  to  receive  annual  performance-based  short-term  incentive  bonuses  (each  a
“STIP Bonus”)  of  up  to  50%  of  his  then-current  Salary,  based  upon  achievement  of  specific  performance  milestones  (“Milestones”)  established  by  the  Compensation
Committee of the Board (“Committee”) in advance and at its discretion. The STIP Bonus shall be paid, at the Company’s option, in cash or restricted stock units (“RSUs”)

3.2.3    Each RSU shall entitle the Employee to receive one (1) share of the Company’s $0.001 par value common stock (“Common Stock”) based on
satisfaction of the Milestones. Upon the Committee’s determination of the satisfaction of the relevant Milestones for any annual STIP or LTIP Bonus, and the amount of
STIP Bonus and LTIP Bonus earned, the Committee shall cause the Company to provide the Employee with an award of cash or RSUs, or a combination of both, in the case
of the STIP Bonus and RSUs in the case of the LTIP Bonus. The number of RSUs to be awarded to the Employee shall be the dollar value of the STIP Bonus or LTIP
Bomus to be paid in RSUs divided by the Fair Market Value (as such term is defined in the Plan) of one share of Common Stock as of the award date.

3.3    Benefits. Employee shall be entitled to the insurance and employee benefits set forth in the Employee Handbook and such other benefits that are made

incurred in connection with the performance of his duties hereunder in accordance with the Company's expense reimbursement policies and procedures.

3.5    Withholding. The Company has the right to withhold from any amount payable hereunder any Federal, state, and local taxes in order for the Company
to satisfy any withholding tax obligation it may have under any applicable law or regulation. Further, the Employee shall make arrangements satisfactory to the Company to
pay  to  the  Company  any  federal,  state  or  local  income  taxes  required  to  be  withheld  with  respect  to  any  Incentive Awards.  If  the  Employee  shall  fail  to  make  such  tax
payments as are required, the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind otherwise due to the Employee any
federal, state or local taxes of any kind required by law to be withheld with respect to any such Incentive Award.

3.6    Incentive Compensation Clawback. Notwithstanding any other provisions in this Agreement to the contrary, any (a) incentive-based compensation
paid to Employee for meeting a financial reporting measure that is based on or derived from financial information or (b) other compensation paid to Employee under this
Agreement  or  any  other  agreement  or  arrangement  with  the  Company  which  is  subject  to  recovery  under  any  law,  government  regulation,  or  stock  exchange  listing
requirement, will be subject to such deductions and clawback as may be required to be made pursuant to such law, government regulation, or NASDAQ listing requirement
(or any policy adopted by the Company pursuant to any such law, government regulation or NASDAQ listing requirement).

3.7    Section 409A. It is intended that any amounts payable under this Agreement (including Section 3 and Section 5.4) and the Company’s and Employee’s
exercise of authority or discretion hereunder shall be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended (“Code”) , including
the Treasury Regulations and other published guidance relating thereto (collectively, “Code Section 409A”), so as not to subject Employee to the payment of any interest or
additional  tax  imposed  under  Code  Section  409A.  This Agreement  shall  be  interpreted  on  a  basis  consistent  with  such  intent.  If  any  payments  or  benefits  provided  to
Employee by the Company, either per this Agreement or otherwise, are non-qualified deferred compensation subject to, and not exempt from, Code Section 409A (“ Subject
Payments”), the following provisions shall apply to such payments and/or benefits:

3.7.1        For  payments  and  benefits  triggered  by  termination  of  employment,  reference  to  Employee’s  “termination  of  employment”  (and  corollary
terms) with the Company shall be construed to refer to Employee’s “separation from service” from the Company (with such phrase determined under Treas. Reg. Section
1.409A-1(h), as uniformly applied by the Company) in tandem with the termination of his employment with the Company.

3.7.2    If Employee is deemed on the date of his “separation from service” to be a “specified employee” (within the meaning of Treas. Reg. Section
1.409A-1(i)), then with regard to any payment that is required to be delayed pursuant to Code Section 409A(a)(2)(B) (the “Delayed Payments”), such payment shall not be
made prior to the earlier of (i) the first day of the seventh month following the date of his “separation from service” and (ii) the date of his death. The Delayed Payments
shall be paid to Employee in a lump sum promptly following the date set forth in the preceding sentence. Any payments other than the Delayed Payments shall be paid in
accordance with the normal payment dates specified herein. In no case will the delay of any of the Delayed Payments by the Company constitute a breach of the Company’s
obligations to Employee.

distinct payments.

3.7.3    Employee’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and

the specified period shall be within the sole discretion of the Company.

3.7.4    Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within

3.7.5        If  the  60  day  period  following  Employee’s  “separation  from  service”  begins  in  one  calendar  year  and  ends  in  a  second  calendar  year  (a
“Crossover 60-Day Period”), then any severance payments subject to Code Section 409A that would otherwise occur during the portion of the Crossover 60-Day Period that
falls  within  the  first  year  will  be  delayed  and  paid  in  a  lump-sum  upon  the  later  of  (i)  January  1  of  the  calendar  year  following  the  calendar  year  in  which  Employee’s
“separation from service” occurs, and (ii) the date when the payment of severance payments would otherwise begin hereunder.

amount unless otherwise permitted by Code Section 409A.

3.7.6    Notwithstanding any other provision of this Agreement to the contrary, in no event shall any Subject Payment be subject to offset by any other

3.7.7    To the extent that any reimbursement or in-kind benefits are Subject Payments: (i) the amount eligible for reimbursement or in-kind benefit in
one calendar year may not affect the amount eligible for reimbursement or in-kind benefit in any other calendar year (except that a plan providing medical or health benefits
may impose a generally applicable limit on the amount that may be reimbursed or paid), (ii) the right to reimbursement or an in-kind benefit is not subject to liquidation or
exchange for another benefit, and (iii) subject to any shorter time periods provided herein, any such reimbursement of an expense or in-kind benefit must be made on or
before the last day of the calendar year following the calendar year in which the expense was incurred.

negotiate in good faith to amend this Agreement in a manner that preserves the original intent of the parties hereto to the extent reasonably possible.

3.7.8    If an amendment of this Agreement is necessary in order for it to comply with Code Section 409A, Employee and the Company agree to

3.8    Limitation on Payments. In the event that the benefits provided for in this Agreement or otherwise payable to Employee (i) constitute “parachute
payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”),  then
Employee’s  benefits  under  this Agreement  shall  be  either  (A)  delivered,  subject  to  any  applicable  tax  or  other  withholdings,  in  full,  or  (B)  delivered,  subject  to  any
applicable tax or other withholdings, to such lesser extent as would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts,
taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by Employee, on an after-tax basis, of the greatest amount of
benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code. Unless the Company and Employee otherwise agree in
writing, any determination required under this Section shall be made in writing by an independent public accountant chosen by the Company (the “Accountant”),  whose
determination  shall  be  conclusive  and  binding  upon  Employee  and  the  Company  for  all  purposes.  For  purposes  of  making  the  calculations  required  by  this  Section,  the
Accountant  may  make  reasonable  assumptions  and  approximations  concerning  applicable  taxes  and  may  rely  on  reasonable,  good  faith  interpretations  concerning  the
application of Section 280G and 4999 of the Code. The Company and Employee shall furnish to the Accountant such information and documents as the Accountant may
reasonably  request  in  order  to  make  a  determination  under  this  Section.  The  Company  shall  bear  all  costs  the Accountant  may  reasonably  incur  in  connection  with  any
calculations contemplated by this Section.

4.     PROTECTION/NON-DISCLOSURE OF COMPANY CONFIDENTIAL INFORMATION AND TRADE SECRETS. Employee acknowledges having
entered  into  that  certain  Confidential  Information,  Non-Disclosure,  and  Trade  Secrets  Agreement  attached  hereto  as Exhibit  A  to  this  Agreement  (“Confidentiality
Agreement”) dated August 10, 2022 with the Company. Employee covenants and agrees to strictly comply with the terms of Confidentiality Agreement during the term of
this Agreement and following the termination of his employment with the Company, as provided for in the Confidentiality Agreement.

5.       TERMINATION. In accordance with Section 1, either party may terminate the employment relationship and this Agreement at any time and for any reason;
provided  that,  unless  otherwise  provided  herein,  either  party  shall  be  required  to  give  the  other  party  at  least  30  days  advance  written  notice  of  any  termination  of  the

herein, and may only be modified by an agreement in writing signed by the party against whom enforcement is sought. Modifications to this Agreement do not change or

arbitration pursuant to this Agreement; (ii) each Party agrees, to the fullest extent permitted under the law, that it will not assert class action or representative action Claims
against the other Party in arbitration or otherwise; and (iii) the Parties shall only submit their own, individual Claims in arbitration and will not seek to represent the interests

(b) “Board” shall mean the Board of Directors of the Company.

(c) “Clawback-Eligible Incentive Compensation” shall mean, in connection with an Accounting Restatement, any Incentive-Based Compensation Received by a Covered

For purposes of this Policy, specific examples of Incentive-Based Compensation include, but are not limited to4:

● Restricted stock, restricted stock units, performance share units, stock options and SARs that are granted or become vested, wholly or in part, on satisfaction of a

●

Financial Reporting Measure performance goal; and
Proceeds received upon the sale of shares acquired through an incentive plan that were granted or vested based, wholly or in part, on satisfaction of a Financial

For purposes of this Policy, Incentive-Based Compensation excludes5:

● Any base salaries (except with respect to any salary increases earned, wholly or in part, based on satisfaction of a Financial Reporting Measure performance goal);
● Bonuses  paid  solely  at  the  discretion  of  the  Committee  or  Board  that  are  not  paid  from  a  “bonus  pool”  that  is  determined  by  satisfying  a  Financial  Reporting

IV.

Determination and Calculation of Erroneously-Awarded Compensation

In the event of an Accounting Restatement, the Committee shall promptly determine the amount of any Erroneously-Awarded Compensation for each Executive Officer in
connection with such Accounting Restatement and shall promptly6 thereafter provide each Executive Officer with a written notice containing the amount of Erroneously-
Awarded Compensation and a demand for repayment or return, as applicable.

(a) Cash Awards . With respect to cash awards, the Erroneously-Awarded Compensation is the difference between the amount of the cash award (whether payable as a

lump sum or over time) that was Received and the amount that should have been received applying the restated Financial Reporting Measure.

(b) Cash Awards Paid From Bonus Pools. With respect to cash awards paid from bonus pools, the Erroneously-Awarded Compensation is the pro rata portion of any

deficiency that results from the aggregate bonus pool that is reduced based on applying the restated Financial Reporting Measure.

(c) Equity Awards .  With  respect  to  equity  awards,  if  the  shares,  options  or  SARs  are  still  held  at  the  time  of  recovery,  the  Erroneously-Awarded  Compensation  is  the
number of such securities Received in excess of the number that should have been received applying the restated Financial Reporting Measure (or the value in excess of
that  number).  If  the  options  or  SARs  have  been  exercised,  but  the  underlying  shares  have  not  been  sold,  the  Erroneously-Awarded  Compensation  is  the  number  of
shares underlying the excess options or SARs (or the value thereof). If the underlying shares have already been sold, then the Committee shall determine the amount
which most reasonably estimates the Erroneously-Awarded Compensation.7

(d) Compensation Based on Stock Price or Total Shareholder Return. For Incentive-Based Compensation based on (or derived from) stock price or total shareholder
return, where the amount of Erroneously-Awarded Compensation is not subject to mathematical recalculation directly from the information in the applicable Accounting
Restatement, the amount shall be determined by the Committee based on a reasonable estimate of the effect of the Accounting Restatement on the stock price or total
shareholder return upon which the Incentive-Based Compensation was Received (in which case, the Committee shall maintain documentation of such determination of
that reasonable estimate and provide such documentation to the Nasdaq in accordance with applicable listing standards).

V.

Recovery of Erroneously-Awarded Compensation

Once  the  Committee  has  determined  the  amount  of  Erroneously-Awarded  Compensation  recoverable  from  the  applicable  Covered  Person,  the  Committee  shall  take  all
necessary  actions  to  recover  the  Erroneously-Awarded  Compensation.  Unless  otherwise  determined  by  the  Committee,  the  Committee  shall  pursue  the  recovery  of
Erroneously-Awarded Compensation in accordance with the below8:

(a) Cash Awards. With respect to cash awards, the Committee shall either (i) require the Covered Person to repay the Erroneously-Awarded Compensation in a lump sum
in  cash  (or  such  property  as  the  Committee  agrees  to  accept  with  a  value  equal  to  such  Erroneously-Awarded  Compensation)  reasonably  promptly  following  the
Restatement Date or (ii) if approved by the Committee, offer to enter into a Repayment Agreement. If the Covered Person accepts such offer and signs the Repayment
Agreement within a reasonable time as determined by the Committee, the Company shall countersign such Repayment Agreement.

6 NTD: The final SEC rule requires the Company to recover the Erroneously-Awarded Compensation “reasonably promptly.” Consider whether to include a more specific
time frame.
7 NTD: Neither the final SEC rule nor the listing standards provide guidance as to how the Company should determine Erroneously-Awarded Compensation if the
underlying shares have been sold. Companies can adopt a policy that specifies how the Company intends to calculate the value of the Erroneously-Awarded Compensation,
for example, “if the underlying shares have been sold, the Erroneously-Awarded Compensation is the higher of the value of the stock upon vesting, exercise or sale.”
Consequently, the Company can leave the policy open for interpretation at the time of any Accounting Restatement or prescribe the guidelines in this Policy.
8 NTD: The final SEC rule requires the Company to recover the Erroneously-Awarded Compensation “reasonably promptly.” Consider whether to include a more specific
time frame or outside date (e.g., require repayment within 120 days, or entry into repayment plan within 30 days).

4

 
 
 
 
 
 
 
 
 
 
 
(b) Unvested Equity Awards . With respect to those equity awards that have not yet vested, the Committee shall take all necessary action to cancel, or otherwise cause to

be forfeited, the awards in the amount of the Erroneously-Awarded Compensation.

(c) Vested Equity Awards . With respect to those equity awards that have vested and the underlying shares have not been sold, the Committee shall take all necessary

action to cause the Covered Person to deliver and surrender the underlying shares in the amount of the Erroneously-Awarded Compensation.

In  the  event  that  the  Covered  Person  has  sold  the  underlying  shares,  the  Committee  shall  either  (i)  require  the  Covered  Person  to  repay  the  Erroneously-Awarded
Compensation in a lump sum in cash (or such property as the Committee agrees to accept with a value equal to such Erroneously-Awarded Compensation) reasonably
promptly following the Restatement Date or (ii) if approved by the Committee, offer to enter into a Repayment Agreement. If the Covered Person accepts such offer and
signs the Repayment Agreement within a reasonable time as determined by the Committee, the Company shall countersign such Repayment Agreement.

(d) Repayment Agreement.  “Repayment Agreement”  shall  mean  an  agreement  (in  a  form  reasonably  acceptable  to  the  Committee)  with  the  Covered  Person  for  the

repayment of the Erroneously-Awarded Compensation as promptly as possible without unreasonable economic hardship to the Covered Person.

(e) Effect of Non-Repayment. To the extent that a Covered Person fails to repay all Erroneously-Awarded Compensation to the Company when due (as determined in
accordance with this Policy), the Company shall, or shall cause one or more other members of the Company to, take all actions reasonable and appropriate to recover
such Erroneously-Awarded Compensation from the applicable Covered Person. [The applicable Covered Person shall be required to reimburse the Company for any
and  all  expenses  reasonably  incurred  (including  legal  fees)  by  the  Company  in  recovering  such  Erroneously-Awarded  Compensation  in  accordance  with  the
immediately preceding sentence.]9

The  Committee  shall  have  broad  discretion  to  determine  the  appropriate  means  of  recovery  of  Erroneously-Awarded  Compensation  based  on  all  applicable  facts  and
circumstances and taking into account the time value of money and the cost to shareholders of delaying recovery. However, in no event may the Company accept an
amount that is less than the amount of Erroneously-Awarded Compensation in satisfaction of a Covered Person’s obligations hereunder.

VI.

Discretionary Recovery

Notwithstanding  anything  herein  to  the  contrary,  the  Company  shall  not  be  required  to  take  action  to  recover  Erroneously-Awarded  Compensation  if  any  one  of  the
following conditions are met and the Committee determines that recovery would be impracticable:

(i) The direct expenses paid to a third party to assist in enforcing this Policy against a Covered Person would exceed the amount to be recovered, after the Company
has made a reasonable attempt to recover the applicable Erroneously-Awarded Compensation, documented such attempts and provided such documentation to the
Nasdaq;

9 NTD: The Company may, but is not required, to include the fees associated with recovery, e.g., legal fees.

5

 
 
 
 
 
 
 
 
 
 
 
 
(ii) Recovery  would  violate  home  country  law  where  that  law  was  adopted  prior  to  November  28,  2022,  provided  that,  before  determining  that  it  would  be
impracticable to recover any amount of Erroneously-Awarded Compensation based on violation of home country law, the Company has obtained an opinion of
home country counsel, acceptable to the Nasdaq, that recovery would result in such a violation and a copy of the opinion is provided to the Nasdaq; or

(iii) Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet

the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.

VII.

Reporting and Disclosure Requirements

The Company shall file all disclosures with respect to this Policy in accordance with the requirements of the federal securities laws, including the disclosure required by the
applicable filings required to be made with the SEC.

VIII.

Effective Date

This Policy shall apply to any Incentive-Based Compensation Received on or after the Nasdaq Effective Date.

IX.

No Indemnification

The Company shall not indemnify any Covered Person against the loss of Erroneously-Awarded Compensation and shall not pay, or reimburse any Covered Persons for
premiums, for any insurance policy to fund such Covered Person’s potential recovery obligations.10

X.

Administration

The Committee has the sole discretion to administer this Policy and ensure compliance with Nasdaq Rules and any other applicable law, regulation, rule or interpretation of
the SEC or Nasdaq promulgated or issued in connection therewith. Actions of the Committee pursuant to this Policy shall be taken by the vote of a majority of its members.
The  Committee  shall,  subject  to  the  provisions  of  this  Policy,  make  such  determinations  and  interpretations  and  take  such  actions  as  it  deems  necessary,  appropriate  or
advisable. All determinations and interpretations made by the Committee shall be final, binding and conclusive.

XI.

Amendment; Termination

The Board may amend this Policy from time to time in its discretion and shall amend this Policy as it deems necessary, including as and when it determines that it is legally
required by any federal securities laws, SEC rule or the rules of any national securities exchange or national securities association on which the Company’s securities are then
listed. The Board may terminate this Policy at any time. Notwithstanding anything in this Section XI to the contrary, no amendment or termination of this Policy shall be
effective if such amendment or termination would (after taking into account any actions taken by the Company contemporaneously with such amendment or termination)
cause  the  Company  to  violate  any  federal  securities  laws,  SEC  rule,  or  the  rules  of  any  national  securities  exchange  or  national  securities  association  on  which  the
Company’s securities are then listed.

10 NTD: While the Company is prohibited from insuring/indemnifying Covered Persons, Executive Officers may separately purchase third-party insurance policies to fund
potential recovery obligations so long as the Company does not directly/indirectly pay/reimburse the cost of the policies.

XII.

Other Recoupment Rights; No Additional Payments

The Committee intends that this Policy will be applied to the fullest extent of the law. The Committee may require that any employment agreement, equity award agreement
or any other agreement entered into on or after the Adoption Date shall, as a condition to the grant of any benefit thereunder, require a Covered Person to agree to abide by
the terms of this Policy. Any right of recoupment under this Policy is in addition to, and not in lieu of, any other rights under applicable law, regulation or rule or pursuant to
the terms of any similar policy in any employment agreement, equity plan, equity award agreement or similar arrangement and any other legal remedies available to the
Company. However, this Policy shall not provide for recovery of Incentive-Based Compensation that the Company has already recovered pursuant to Section 304 of the
Sarbanes-Oxley Act or other recovery obligations.

XIII.

Successors

This Policy shall be binding and enforceable against all Covered Persons and their beneficiaries, heirs, executors, administrators or other legal representatives.
