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 lead through a
novel, proprietary and patent-pending process that we developed and named “AquaRefining”. Since our formation, we have focused our
efforts on the development and testing of our AquaRefining process, the development of our business plan, the raise of our present working
capital and the development of our initial lead acid battery, or LAB, recycling facility in the Tahoe Regional Industrial Center, McCarran,
Nevada (“TRIC”).

We have completed the development of our first LAB recycling facility at the Tahoe Regional Industrial Center, McCarran, Nevada,
or “TRIC,” and commenced production of battery breaking and limited operations during the first quarter of 2017. The TRIC facility will
produce recycled lead, consisting of lead compounds, ingoted hard lead and ingoted AquaRefined lead as well as plastic. We commenced
the shipment of products for sale, consisting of lead compounds and plastics, in April 2017 and as of the date of this report all revenue has
been derived from the sale of lead compounds and plastics. 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.

Since our organization in 2014, we have engaged in several capital raising transactions, the most recent of which are summarized

below in “Management’s Discussion and Analysis of Financial Condition and Results of Operations - General.”

Overview

Aqua Metals is seeking to reinvent lead recycling with its patented and patent-pending AquaRefining™ technology. Unlike smelting,
AquaRefining  is  a  room  temperature,  water-based  process.  It  is  deployed  as  a  factory  built  modular  system  which  allows  the  lead-acid
battery industry to simultaneously improve environmental impact and scale production to meet demand. Aqua Metals is based in Alameda,
California, and has built its first recycling facility in Nevada’s Tahoe Reno Industrial Complex. Lead is a globally traded commodity with a
worldwide  market  value  in  excess  of  $20  billion.  Lead  acid  batteries  (LABs)  are  the  primary  consumer  use  of  all  lead  produced  in  the
world.  Because  the  chemical  and  metallurgical  properties  of  lead  allow  it  to  be  recycled  and  reused  indefinitely,  LABs  are  also  the
dominant feed source for lead production across the world. As such, LABs are almost 100% recycled for purposes of capturing the lead
contained  therein  for  re-use.  We  believe  that  our  proprietary  AquaRefining  process  will  provide  for  the  recycling  of  LABs  and  the
production  of  a  high  purity  lead  with  fewer  environmental  and  regulatory  issues  than  is  possible  with  conventional  methods  of  lead
production.

In  recent  years,  recycled  lead  has  become  increasingly  important  to  LAB  production.  Recycled  lead  surpassed  mined  lead  in  the
1990s and now represents more than 60% of the lead content in new LABs. Whether it is produced from lead ore or recycled LABs, lead
has historically been produced by smelting. Smelting is a high-temperature, metallurgical/chemical reduction, energy intensive and often a
highly  polluting  process. As  a  consequence  of  the  environmental  and  health  issues,  lead  smelting  has  become  increasingly  regulated  in
many countries. In the U.S., regulatory non-compliance has forced the closure of large lead smelters in Vernon, California, Frisco, Texas
and Herculaneum, Missouri over the last several years. In response to increasing environmental regulation over the past three decades, there
has been an expansion of LAB smelting capacity in Mexico and other less regulated countries. The resulting transportation of used LABs
from  where  they  originate  in  the  U.S.  to  smelters  in  Mexico,  South  Korea,  the  Philippines  and  elsewhere  is  an  increasingly  significant
logistical and global environmental cost.

AquaRefining  uses  a  bio-degradable  aqueous  solvent  and  a  novel  ambient  temperature  electro-chemical  process  to  produce  lead
suitable  for  use  in  LAB  production.  We  believe  that AquaRefining  can  provide  a  more  efficient  production  process  as  compared  with
alternative methods of producing equivalent grades of lead. We also have the potential to locate AquaRefining facilities closer to the source
of  used  LABs,  thereby  reducing  transport  costs  and  supply  chain  bottlenecks.  On  this  basis,  we  believe  that  AquaRefining  reduces
environmental  plant  emissions,  health  concerns  and  permitting  needs  compared  with  lead  smelting.  We  believe  that  the  combined
advantages offered by AquaRefining represent a potential step change in lead recycling technology and recovered product quality, one that
can deliver advantages in footprint and logistics while reducing the environmental impact of lead recycling.

The modular nature of AquaRefining makes it possible both to start LAB recycling at a smaller scale than is possible with a typical
smelter  setup,  and  to  add AquaRefining  to  existing  battery  recycling  operations  to  expand  production  capacity  or  to  reduce  smelting
processes. Our plan is to pursue two complementary business streams. The first is to supply AquaRefining and supporting equipment to
third parties to supplement or replace smelting in their battery recycling operations. We intend to pursue this at least initially through our
relationship with Johnson Controls Inc., with which we have entered exploratory discussions centered on the addition of AquaRefining to
one  of  its  existing  battery  recycling  operations.  The  second  is  to  expand  our  own  lead  recycling  operations,  subject  to  our  receipt  of
additional capital.

Our Markets

The Lead Market

Lead  is  a  globally  traded  commodity  and  is  the  essential  component  of  over  95%  of  the  world’s  rechargeable  batteries.  Lead  is
globally traded primarily on the London Metals Exchange, or LME, although the smaller Shanghai Metals Exchange (SHME) also trades
the  element.  Conventionally  in  the  industry,  there  are  two  separate  groupings  of  lead:  i)  primary  lead  which  refers  to  lead  produced  at
smelters that use mined lead concentrates (generally lead sulfide) as their primary feedstock, and ii) secondary lead which refers to lead
smelters utilizing LABs as their main feed source.

Originally, the majority of the lead used in batteries was sourced from primary smelters but in recent decades, secondary lead has
grown  to  become  the  dominate  product  used.  Industry  data  shows  that  six  million  metric  tons  of  lead  was  produced  in  1995  of  which
approximately 45% was primary and 55% was from secondary sources. Twenty years later, by 2015, global lead production had increased
to approximately 11 million metric tons, of which more than 65% was secondary. Importantly, primary lead production had increased only
marginally  during  this  period.  This  marginal  increase  is  because  lead-zinc  mine  deposits  are  being  depleted  across  the  globe  in  existing
mines. As such, an increasing quantity of primary lead is now the predominate byproduct of zinc mining.

In 2005, secondary lead traded on the LME in a range of $1,000 to $1,200 per metric ton. During 2017, secondary lead traded in a

range of approximately $2,000 to $2,600 per metric ton.

As noted above, although lead is traded as a commodity on the LME/SHME, the major sales are the sales directly between producers

and users (whom are typically battery manufacturers). The LME daily price is used as the benchmark in forming the basis of physical
trades, forward contracts and hedge strategies for both primary and secondary lead. Based on market knowledge with buyers of lead in the
U.S. and Global lead markets, different grades (termed alloys) of lead are traded at a premium to the LME price. Lead by-products (lead
compounds) can trade at a discount to the LME based on the amount of lead content. 

Lead Smelting

Currently,  smelters  produce  virtually  all  the  world’s  mined  and  recycled  lead.  Smelting  is  an  energy  intensive  and  often  highly
polluting process. At its core, smelting is a high temperature (excess of 1000°C) metallurgical reduction process in which lead compounds
are heated and reacted with various reducing agents to remove the oxygen, sulfur, and other impurities. The process leaves behind bullion
lead and waste slag. In smelting, depending upon the operation, 0.5% to 5% of the lead is lost in the “slag”, with the resultant lead bullion
containing both wanted and unwanted impurities.

In addition to the inefficiencies associated with smelting, it can generate large volumes of toxic solid, liquid, particulate and gaseous
waste.  In  developed  countries,  there  is  both  increased  environmental  regulation  and  enforcement  of  such,  including  monitoring  of
permissible  blood  lead  levels  in  employees  and  local  populations.  These  regulations  and  the  increasing  enforcement  have  made  it  more
expensive  to  operate  smelters.  According  to  a  report  titled  “Hazardous  Trade?”  produced  by  the  Secretariat  of  the  Commission  for
Environmental Cooperation in 2013, this has led to a decline of lead smelters in the U.S., an expansion of smelting operations in Mexico
and a resultant increase in the export of used LABs from the U.S. followed by the re-import of recycled lead. This trade is believed to be
largely  driven  by  the  lower  costs  related  to  the  less  stringent  environmental  standards  and  enforcement  in  Mexico.  For  the  foregoing
reasons, we believe that lead smelting facilities are increasingly located in less regulated areas remote from both the source of used LABs
and the demand for lead. We believe that the remote location of smelting increases the transport costs to the production of recycled lead.

Lead Acid Batteries

Although  the  LAB  is  one  of  the  earliest  battery  technologies,  in  terms  of  energy  capacity  deployed  and  installed  manufacturing
capacity,  it  dominates  the  battery  industry  today.  Historically,  the  largest  market  for  LABs  has  been  as  starter  batteries  for  vehicles.
However,  with  the  increasing  electrical  load  on  modern  vehicles  and  the  adoption  of  “Stop-Start”  conventional  12V  “starter  batteries”,
LABs are evolving into more capable and higher value products. At the same time, large new markets such as Cell Tower, Data Center and
Industrial back-up are adding to demand. Consequently, existing LAB production facilities are being expanded and new facilities are being
built. 

 4

 
 
 
 
 
 
 
 
 
 
 
 
 
According  to  CHR  Metals,  total  lead  output  in  2017  was  expected  to  be  20%  higher  than  it  was  in  2012.  Similar  prospects  for
healthy growth in the lead industry continue to be published and support continued growth in demand for lead for at least the next 20 years.
We believe that grid storage and other energy storage applications linked to renewable energy (solar and wind) will also generate increased
demand for LABs, where low cost, safety and reliability will make them attractive options.

The increase in LAB manufacturing in general and particularly in China, India and Southeast Asia, has increased demand for lead,
putting  pressure  on  global  recycling  networks  to  meet  this  demand. At  present,  we  believe  that  much  of  the  LAB  recycling  performed
outside  of  the  U.S.,  Canada,  the  EU,  Japan,  and Australia  is  carried  out  in  outdated  facilities  with  poor  environmental  standards  and
insufficient enforcement. China, India, Pakistan and South America appear to be moving toward tougher regulation and enforcement. We
believe that this will drive a demand in foreign markets for more less polluting LAB recycling processes.

AquaRefining Process

We developed AquaRefining to be a less expensive, cleaner and modular alternative to smelting. Our process has two key elements,
both of which are integral to our issued patents and pending-patent applications. The first is our use of a proprietary, non-toxic solvent that
dissolves  lead  compounds.  The  second  is  a  proprietary  electro-chemical  process  and  electrolyzer  that  converts  the  dissolved  lead
compounds into high purity lead suitable for use in LAB production.

Similar to conventional LAB smelter recycling, our AquaRefining process begins with the crushing of used LABs and the separation
of the metallic lead, active material (lead compounds), sulfuric acid and plastic for recycling. The active material (lead compounds) are first
processed to remove sulfur and then dissolved in our solvent. Lead is then plated from the solvent using our patented and patent-pending
process allowing the solvent to be reused.

Our AquaRefining process can generate the following outputs:

● Lead and lead-based products, including high purity lead, lead alloys and lead compounds which are primarily intended for
the  LAB  industry.  We  are  also  exploring  higher  value  lead  based  products  which  may  offer  performance  and  life-cycle
benefits to the LAB industry; and

● Recovered plastic chips, intended for re-use in the manufacture of battery casings and other recycled plastic products.

We expect to derive revenue primarily from the sale of lead-based products, with additional revenue derived from the sale of plastic

chips.

A  significant  benefit  of  our AquaRefining  process  is  that  it  is  capable  of  producing  high  purity  (sometimes  called  primary  grade)

lead from secondary sources. Primary grade lead is sold directly to battery companies.

Another significant benefit of our process is that we designed our AquaRefining equipment to be manufactured on a purpose-built
production line in standard sized modules. This is not possible with the smelting process, as smelters need to be constructed on site. This
gives us the ability to provide AquaRefining systems with capacities ranging from four metric tons per day to more than 400 metric tons
per day all based on our standard module.

Lead recycling is subject to a variety of domestic and international regulations related to hazardous materials, emissions, employee
safety and other matters. While our operations will be subject to these regulations, we believe that one of our potential advantages will be
our  ability  to  conduct  lead  recycling  operations  with  less  regulatory  cost  and  burden  than  smelting  operators  due  to  the  nature  of  our
process.  One  of  our  key  objectives  will  be  to  educate  regulators  and  the  public  as  to  the  environmental  benefits  of AquaRefining.  We
believe  that  we  have  the  potential  to  develop  a  business  model  that  offers  the  opportunity  to  conduct,  in  an  environmentally  friendly
manner, an important recycling activity that historically has been conducted in an often highly polluting manner.

Our Business Model

Overall, our objective is to progress the lead recycling industry from one which is based primarily on smelting to one which is based
on AquaRefining. Our expectation is that this will be a moderately paced process of evolution in which multiple business models will be
evaluated. The two business models that we are currently most focused on are:

1)

the supply  of AquaRefining  and  supporting  equipment  and  services  to  third  parties  to  use in  their  recycling  operations  on  a
licensing model. We are currently focused on exploring this business stream through our relationship with Johnson Controls;

 5

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
2)

the expansion of our own AquaRefining capacity and facilities, subject to our receipt of additional capital.

The  market  for  lead  is  global  in  scale  but  local  in  nature  and  execution,  with  large  differences  in  local  regulation,  custom  and
practice. 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.

Lead recycling is subject to a variety of domestic and international regulations related to hazardous materials, emissions, employee
safety and other matters. While our operations will be subject to these regulations, we believe that one of our potential advantages will be
our ability to conduct lead recycling operations with less regulatory cost and burden than smelting operators. One of our key objectives will
be to educate regulators and the public as to the environmental benefits of AquaRefining. We believe we have the potential to develop a
business model that offers less regulatory cost and burden and the opportunity to conduct business in a socially responsible manner.

In  the  U.S.  and  similarly  regulated  countries,  our  plan  is  to  build  and  operate  LAB  recycling  facilities,  both  directly  and  in
association with third parties through joint ventures, licensing and direct sales. As an example, on February 7, 2017, we entered into a series
of  agreements  with  Johnson  Controls  Inc.,  (Johnson  Controls),  pursuant  to  which,  among  other  things,  we  agreed  to  work  with  Johnson
Controls on the development of a program for the installation of greenfield lead recycling facilities and conversion of Johnson Controls’
and certain strategic partners’ of Johnson Controls existing lead smelters throughout North America, China and Europe to a lead recycling
process utilizing our proprietary and patented AquaRefining technology and equipment, know-how and services.

Competition

At the present time, our primary competition in the production of lead comes from operators of existing smelters and other parties
heavily  invested  in  the  existing  supply  chain  for  smelting.  Our  approach  to  this  competition  is  to  make AquaRefining  available  for  the
conversion of existing smelter-based facilities. However, it is prudent to assume that outside of our strategic relationships, a conversion to
AquaRefining  may  be  resisted  by  some  of  the  incumbent  lead  producers.  Competition  in  the  supply  of  lead  from  such  incumbents  may
come in the form of price competition for lead produced. However, to the extent we are successful in being a producer of high quality lead
without the regulatory costs or burden associated with smelting, we should be able to compete effectively with smelting as the preferred
method of recycling lead, at least in the more regulated jurisdictions.

Another area where incumbents may seek to compete is in controlling access to used LABs. The market for used LABs is made up
of the members of the LAB reverse supply chains, including auto repair shops, auto parts stores and auto dealers, LAB manufacturers who
operate their own smelting operations and third parties who  engage  in  the  purchase  and  sale  of  used  LABs.  We  believe  that  some  LAB
manufacturers who maintain their own smelting operations may feel threatened by our AquaRefining process. Such parties may attempt to
restrict our access to used LABs. We have assumed at least some level of interference by incumbents, however, based on our operations to
date, including our discussions and arrangements with certain suppliers of used LABs, we do not view access to used LABs be a significant
risk to our LAB recycling operations.

Our business plan is not dependent on the acceptance of our process by lead smelters. We still intend to initially focus on operating
our own AquaRefining facilities directly and working with Johnson Controls to implement Aqua Refining in a nominated lead smelting
facility followed by deployments with additional 3rd parties to propagate AquaRefining as the technology of choice for recycling LABs.

We do not expect to experience significant competition in connection with our sale of lead. We believe that the market for lead is
established,  fluid  and  effective;  and  like  the  markets  for  other  natural  resources,  such  as  oil,  gas,  gold,  silver,  etc.,  we  do  not  expect  to
encounter  any  issues,  conditions  or  qualifications  for  the  sale  of  our  lead  production  at  prevailing  market  prices  set  by  the  LME.  The
vertically integrated LAB manufacturers who conduct smelting operations also are buyers of lead from third parties. We believe that they
will still purchase lead from us if we are able to offer it at the market price.

Our First Recycling Facility: McCarran, Nevada

In  May  2015,  we  purchased  11.73  acres  of  undeveloped  land  in  the  Tahoe  Reno  Industrial  Center  (TRIC),  at  McCarran,  Nevada

where we subsequently built a 136,750 square foot LAB recycling facility.

The building phase was completed by August 2016, at which time we started installing and commissioning equipment. We installed
and  commissioned  the  first  production AquaRefining  module  in  October  2016  and  produced  our  first  lead  ingot  using  electrolyte  we
produced  on-site  using  materials  supplied  by  a  3rd  party,  which  were  recovered  from  recycled  batteries.  We  verified  that  the  lead  we
produced by this method was over 99.99 percent pure.

We commenced initial battery breaking during December 2016 and progressed to regular single shift operation of the battery breaker
in January 2017. From late 2016 through the date of this report, we implemented a number of upgrades to the facility, the battery breaking
and separation processes and other more conventional aspects of our process.

By December 2017, we had installed 16 AquaRefining modules. However, we encountered an issue which required the retrofitting
of all 16 modules. As of the date of this report, we expect to complete the retrofit of all 16 modules by late March or early April and to
begin  to  bring  all  16  modules  into  commercial  operation.  However,  due  to  the  delays  and  unforeseen  issues  in  the  completion  of  the
AquaRefining  production  line  we  have  experienced  to  date,  there  can  be  no  assurance  that  we  will  not  encounter  additional  delays  and
issues.  During  2018,  we  expect  to  continue  to  invest  in  further  expanding  our  capability  and  capacity  at  our  Nevada  facility,  including
additional AquaRefining modules, subject to our receipt of additional capital.

Supply, Off-Take and Other Strategic Agreements

In support of our first facility, we have entered into a series of agreements and relationships providing for our supply of LABs and
the  off-take  of  the  recycled  lead  we  produce. As  described  in  more  detail  below,  Interstate  Battery  has  agreed  to  supply  us  with  LABs
pursuant to a written agreement entered into in May 2016. In addition, we have established an important relationship Battery Systems. Inc.,
an independent LAB distributor with a distribution facility located next to our TRIC facility, for Battery Systems’ supply of used LABS to
us. We have also entered into an agreement with Johnson Controls pursuant to which Johnson Controls has agreed to purchase from us,
recycled  lead  on  both  a  tolling  (fee  to  convert  used  LABs  to  recycled  materials)  and  merchanting  (sale  of  recycled  materials)  basis.
Consequently, we believe that we have secured an ample supply of used LABs and demand for our lead-based products for the foreseeable
future. In addition, we entered into a separate agreement with Johnson Controls pursuant to which we agreed to work with Johnson Controls
on  the  development  of  a  program  for  the  installation  of  new  greenfield  builds  and  conversion  of  Johnson  Controls  and  certain  strategic
partners of Johnson Controls existing lead smelters throughout North America, China and Europe to a lead recycling process utilizing our
proprietary and patent-pending AquaRefining technology and equipment, know-how and services.

Johnson Controls Agreements

Equipment  Supply  Agreement. We  entered  into  an  equipment  supply  agreement  dated  February  7,  2017  with  Johnson  Controls
pursuant to which we agreed to collaborate on the development of a program for the installation of new greenfield builds and conversion of
existing Johnson Controls and certain strategic partners of Johnson Controls’ existing lead smelters to a lead recycling process utilizing our
proprietary and patent-pending AquaRefining technology and equipment, know-how and services. We have agreed with Johnson Controls
to develop an appropriate program blueprint, and enter into a definitive development program agreement reflecting that blueprint, pursuant
to which we will provide to Johnson Controls and certain strategic partners of Johnson Controls, by way of licensing or sale, the following
products and services in the regions of North America, Europe and China:

● AquaRefining technology  and  the  related  equipment,  engineering  and  systems  integration  support  sufficient to  convert  or  retrofit
existing smelter-based operations and/or the construction of new Johnson Controls and Johnson Controls’ strategic partners’ battery
recycling facilities based on our AquaRefining technology;

● Training, evaluation and certification of Johnson Controls’ operations personnel sufficient for such personnel to competently operate

our AquaRefining technology and equipment; and

● Ongoing technical support, maintenance services and warranties.

We plan to provide the above services and equipment to Johnson Controls on a serviced license basis, including Johnson Controls’
ongoing licensing fees payable to us based on the operational capacity of the AquaRefining equipment supplied by us. We have agreed not
to license our AquaRefining technology and equipment to third parties in the aforementioned regions until such as we and Johnson Controls
have agreed on certain matters relating to the initial conversion of a Johnson Controls facility. Johnson Controls and we have agreed to use
good  faith,  commercial  best-efforts  to  conclude  the  discussion  and  negotiation  of  the  development  program  agreement  no  later  than
April  30,  2018,  and  to  enter  into  a  definitive  development  program  agreement  no  later  than  June  30,  2018.  The  equipment  supply
agreement  may  be  terminated  by  either  party  upon  60  days’  prior  written  notice  if  the  parties  have  not  entered  into  the  development
program agreement by June 30, 2018, of which there can be no assurance. The equipment supply agreement allows each party the right to
seek  early  termination  based  on  a  material  breach  by  the  other  party  that  goes  uncorrected  for  30  days  following  notice  of  breach.  The
equipment  supply  agreement  contains  representations,  warranties  and  indemnities  that  are  customary  to  commercial  agreements  of  this
nature.

Tolling/Lead Purchase Agreement. We have entered into a tolling/lead purchase agreement dated February 7, 2017 with Johnson
Controls pursuant to which we have agreed to sell to Johnson Controls, and Johnson Controls has agreed to purchase from us, recycled lead
on both a tolling (fee to convert used LABs to recycled materials) and merchanting (sale of recycled materials) basis.

Pursuant to the agreement, Johnson Controls has agreed to purchase from us, and we have agreed to sell to Johnson Controls, up to
100% of the recycled lead we produce for automotive applications, other than by way of tolling arrangements, on a monthly basis, unless
we receive notice from Johnson Controls six months advance of its intention to purchase less than 100% of our output in any given month.
Our agreement with Johnson Controls excludes, and we are free to manufacture and sell to third parties, recycled lead for non-automotive
uses, such as stationery batteries for back-up power systems for Internet/Cloud applications or grid scale storage applications.

We have also agreed to provide tolling services to Johnson Controls whereby Johnson Controls will deliver to us used lead acid
batteries, or LABs, and we will recycle the used LABs and return the recycled lead to Johnson Controls for a fee. Johnson Controls has
agreed to send to us for tolling, and we have agreed to toll for Johnson Controls, used LABs representing a significant allocation of the
production  capacity  of  our  initial  recycling  facility  in  McCarran,  Nevada.  During  fiscal  year  2017,  the  vast  majority  of  revenues  were
derived from Johnson Controls.

The tolling/lead purchase agreement has a minimum term of five years and upon the expiration of the initial term the agreement,
either party can terminate the agreement upon three years prior written notice. Either party may elect to terminate the agreement for any
reason  after  the  second  anniversary  of  the  agreement,  which  termination  shall  be  effective  on  the  third  anniversary  of  the  notice  of
termination. Either party may terminate the agreement on ten days’ prior written notice of breach that goes uncorrected during the notice
period.  The  tolling/lead  purchase  agreement  contains  representations,  warranties  and  indemnities  that  are  customary  to  commercial
agreements of this nature.

Interstate Battery Partnership

On May 18, 2016, we entered into a supply agreement with Interstate Battery pursuant to which Interstate Battery agreed to sell to
us,  and  we  agreed  to  buy  from  Interstate  Battery,  used  LABs.  Interstate  Battery  will  sell  us  used  LABs  on  a  cost-plus  basis  and  the
agreement  subjects  us  and  Interstate  Battery  to  certain  minimum  purchase  and  sale  requirements.  We  have  granted  Interstate  Battery
limited rights of first refusal to supply our future AquaRefineries. Our agreement with Interstate Battery is for an initial term of 18 months
from the date of first delivery of used LABs to us and will be subject to automatic renewals thereafter unless either party elects to terminate
the agreement. The agreement allows each party the right to seek early termination based on certain commercial contingencies. The supply
agreement contains representations, warranties and indemnities that are customary to commercial agreements of this nature.

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 six granted/allowed patents consisting of one each in the U.S. (9837689), Canada (2930945), South Africa
(2016-04083), Korea (101739414), Japan (6173595) and Australia (2014353227). The claims of the granted patents substantially address
the same subject matter and are drawn to various aspects of processing lead materials using an aqua refining process. Differences in the
claim number and scope are due to local rules and practice. We have multiple filed patent applications organized in more than five patent
families, in up to 20 countries and patent territories.

We intend to continue to prepare and file domestic and foreign patent applications covering expanding aspects and applications of

our technology, as circumstances warrant.

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

Trademark Portfolio

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

● AQUA METALS (US and 15 foreign countries)
● AQUAREFINING (US and 11 foreign countries)
● AQUAREFINE (US only)

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 in the United States will be subject to the Federal, state and local environmental, health and safety laws applicable to
the reclamation of LABs. While the lead reclamation process itself is generally not subject to Federal permitting requirements, depending
on how any particular operation is structured, our facilities may have to obtain environmental permits or approvals from Federal, state or
local regulators to operate, including permits or regulatory approvals related to air emissions, water discharges, waste management, and the
storage  of  LABs  on-site  should  that  become  necessary.  We  may  face  opposition  from  local  residents  or  public  interest  groups  to  the
installation  and  operation  of  our  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  are  subject  to  environmental  health,  safety  and  transportation  laws  and
regulations that govern the management of and exposure to hazardous materials such as the lead and acids involved in LAB reclamation.
These  include  hazard  communication  and  other  occupational  safety  requirements  for  employees,  which  may  mandate  industrial  hygiene
monitoring of employees for potential exposure to lead. Failure to comply with these requirements could subject our business to significant
penalties (civil or criminal) and other sanctions that could adversely affect our business. Changes to these regulatory requirements in the
future could also increase our costs, require changes in or cessation of certain activities, and adversely affect the business.

The  nature  of  our  operations  involves  risks,  including  the  potential  for  exposure  to  hazardous  materials  such  as  lead,  that  could
result in personal injury and property damage claims from third parties, including employees and neighbors, which claims could result in
significant costs or other environmental liability. Our operations also pose a risk of releases of hazardous substances, such as lead or acids,
into  the  environment,  which  can  result  in  liabilities  for  the  removal  or  remediation  of  such  hazardous  substances  from  the  properties  at
which they have been released, liabilities which can be imposed regardless of fault, and our business could be held liable for the entire cost
of cleanup even if we were only partially responsible. Like any manufacturer, 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 (“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 operations will be subject to the environmental, health and safety laws of
the countries where we do business, including permitting and compliance requirements that address the similar risks as do the laws in the
United States, as well as international legal requirements such as those applicable to the transportation of hazardous materials. Depending
on the country or region, these laws could be as stringent as those in the US, or they could be less stringent or not as strictly enforced. In
some countries in which we are interested in expanding our business, such as Mexico and China, the relevant environmental regulatory and
enforcement frameworks are in flux and subject to change. Therefore, while compliance with these requirements will cause our business to
incur costs, and failure to comply with these requirements could adversely affect our business, it is difficult to evaluate such potential costs
or adverse impacts until such time as we decide to initiate operations in particular countries outside the United States.

Item 1A.

Risk Factors

There  are  numerous  and  varied  risks,  known  and  unknown,  that  may  prevent  us  from  achieving  our  goals.  If  any  of  these  risks
actually occur, our business, financial condition or results of operation may be materially adversely affected.  In such case, the trading
price of our common stock could decline and investors could lose all or part of their investment.

Risks Relating to Our Business

Since we have a limited operating history and have only recently commenced revenue producing operations, it is difficult for
potential investors to evaluate our business. We formed our corporation in June 2014 and only commenced revenue producing operations
in the first quarter of 2017. From inception through December 31, 2017, we have generated a total of $2.1 million of revenue, all of which
was  derived  from  the  sale  of  lead  compounds  and  plastics  during  the  year  ended  December  31,  2017.  To  date,  our  operations  have
consisted  of  the  development  and  testing  of  our AquaRefining  process,  the  construction  of  our  initial  LAB  recycling  facility  in  Tahoe
Regional  Industrial  Center,  McCarran,  Nevada  (“TRIC”),  the  continuing  development  of  our  LAB  recycling  operations  at  TRIC  and
limited revenue producing operations as we bring those LAB recycling operations online. Our limited operating history makes it difficult
for  potential  investors  to  evaluate  our  technology  or  prospective  operations. As  an  early  stage  company,  we  are  subject  to  all  the  risks
inherent in the initial organization, financing, expenditures, complications and delays in a new business, including, without limitation:

● the timing and success of our plan of commercialization and the fact that we continue to experience delays in completing our

LAB recycling operations at TRIC;

● our ability to bring modules online and ramp up production on a commercial scale;

● our ability to profitably operate our AquaRefining process on a commercial scale;

● our ability to realize the expected benefits of our strategic partnership with Johnson Controls;

● our ability to procure LABs in sufficient quantities at competitive prices; and

● our ability  to  receive  proper  certification  from  and  meet  the  requirements  of  our  customers regarding  the  purity  of  our

AquaRefined lead.

Investors should evaluate an investment in us in light of the uncertainties encountered by developing companies in a competitive

environment. There can be no assurance that our efforts will be successful or that we will ultimately be able to attain profitability.

Our business is dependent upon on our development and successful implementation of novel and unproven technologies and
processes and there can be no assurance that we will be able to develop and 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 our lead
recycling  operations  are  widely  used  and  proven,  the AquaRefining  component  of  our  lead  recycling  operations  is  largely  novel  and
unproven. While we have shown that our proprietary technology can produce AquaRefined lead on a small scale, we have only recently
completed, and have not put into operation, the processes that we believe will support the production of AquaRefined lead on a commercial
scale. Further, as we complete our AquaRefining production line, we continue to encounter unforeseen complications that have delayed the
installation  and  commissioning  of  our AquaRefining  modules  and  the  integration  of  our AquaRefining  process  with  the  traditional  lead
recycling  operations.  For  example,  we  most  recently  had  to  develop  special  processes  and  equipment  to  deal  with  an  unexpected
development  in  the  form  of  “sticky  lead,”  whereby  the  AquaRefined  lead  produced  by  our  electrolyzers  sticks  to  the  AquaRefining
modules’ exit chute and fails to exit without manual intervention. We believe we have developed a process that will allow for the exit of
the AquaRefined  lead  without  manual  intervention,  however,  this  additional  process  will  require  a  certain  amount  of  retrofitting  of  our
modules  that  will  delay  our  planned  commercial  operation  of  all  16  modules.  There  can  be  no  assurance  that  we  will  not  encounter
additional unforeseen complications that will cause further delays in our planned commercial operation of our AquaRefining modules or
prevent us from commencing commercial production of AquaRefined lead at all.

 11

 
 
 
 
 
 
 
 
 
 
 
 
 
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, 2017, we had total cash of $22.8 million and working capital of $21.9 million.
As  of  the  date  of  this Annual  Report,  we  believe  that  we  have  working  capital  sufficient  to  fund  the  commissioning  and  commercial
operation  of  16 AquaRefining  modules  at  TRIC  over  the  12  months  from  the  date  of  this Annual  Report.  However,  we  will  require
additional capital in order to increase production of AquaRefined lead at TRIC beyond that planned for 16 modules, to work with Johnson
Controls on equipment integration and licensing to third parties, to fund working capital needs related to the ramp-up of our operations and
to fund our continued losses from operations until such time as we are able to achieve positive cash flow from operations. There can be no
assurance that we will be able to acquire the necessary funding on commercially reasonable terms or at all.  There can also be no assurance
we  will  be  able  to  conclude  the  proposed  development  agreement  with  Johnson  Controls.  We  intend  to  seek  additional  funds  through
various financing sources, including the sale of our equity and debt securities, licensing fees for our technology, joint ventures with capital
partners  and/or  project  financing  of  our  recycling  facilities.  However,  there  can  be  no  assurance  that  such  funds  will  be  available  on
commercially  reasonable  terms,  if  at  all.  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.

We are subject to restrictive debt covenants that may limit our ability to run our business, finance our capital needs and pursue
business opportunities and activities. As of the date of this Annual Report, we are indebted to Green Bank for approximately $9.8 million
and  Interstate  Battery  for  approximately  $6.0  million,  all  of  which  is  secured  by  liens  on  substantially  all  of  our  assets.  The  credit
agreements governing such indebtedness contain covenants that limit our ability to take certain actions. These covenants could limit our
ability to finance our future operations and capital needs and our ability to pursue business opportunities and activities that may be in our
interest. If we breach any of these covenants, the debt holder could declare a default under the credit agreement, in which case all of the
indebtedness  may  then  become  immediately  due  and  payable.  In  addition,  any  default  under  one  credit  agreement  could  lead  to  an
acceleration  of  debt  under  the  other  credit  agreement  pursuant  to  cross-acceleration  or  cross-default  provisions.  If  the  debt  under  either
credit agreement is accelerated, we may not have, or be able to obtain, sufficient funds to make these accelerated payments. In addition,
since all of the indebtedness to Green Bank and Interstate Battery is secured by substantially all of our assets, a default under either credit
facility could enable the debtholder to foreclose on its security interest and attempt to seize our assets. The affirmative and negative debt
covenants  could  materially  adversely  impact  our  ability  to  operate  and  finance  our  business.  In  addition,  our  default  under  any  of  these
covenants could subject us to accelerated debt payments or foreclosure proceedings that could threaten our ability to continue as a going
concern.

Interstate Battery currently claims that we are in breach of a negative covenant with Interstate Battery and we have not been
able to comply with our debt service covenant with Green Bank. As of the date of this report, Interstate Battery has raised a claim that we
are in technical breach of a negative covenant under our loan with Interstate Battery. The claimed breach relates to our failure to obtain
Interstate Battery’s prior written consent to our acquisition of Ebonex IPR, Ltd. We believe we will be able to resolve the matter. However,
in  the  event  we  are  unable  to  resolve  the  matter,  Interstate  Battery  may  declare  a  default  under  the  loan  and  attempt  to  accelerate  the
payment of all amounts thereunder. There can be no assurance we will be able to resolve the claimed breach or that Interstate Battery will
not declare a default under the loan and attempt to accelerate the payment of all amounts thereunder. In addition, our credit agreement with
Green Bank requires, among other affirmative and negative covenants, that we maintain a minimum debt service coverage ratio of 1.25 to
1.0 beginning with the twelve-month period ending March 31, 2017. We failed to meet the minimum debt service coverage ratio covenant
as of March 31, June 30, September 30, and December 31, 2017, and we were required to obtain a waiver of the minimum debt service
coverage  ratio  covenant  from  Green  Bank  for  such  periods.  There  can  be  no  assurance  that  Green  Bank  will  provide  waivers  of  this
covenant, or any other covenant that we may fail to satisfy, going forward. Our default under either the Interstate Battery or Green Bank
loan  covenants  could  subject  us  to  accelerated  debt  payments  or  foreclosure  proceedings  that  could  threaten  our  ability  to  continue  as  a
going concern.

In the event of the acceleration of either the Interstate Battery or Green Bank loans, we will need additional financing to satisfy
our obligations under the loans, which additional financing may not be available on reasonable terms or at all. As noted above, as of
the date of this report, we are indebted to Green Bank for approximately $9.8 million and Interstate Battery for approximately $6.0 million.
The  credit  agreements  governing  such  indebtedness  contain  various  affirmative  and  negative  covenants  and  if  we  breach  any  of  these
covenants,  the  debt  holder  could  declare  a  default  under  the  credit  agreement,  in  which  case  all  of  the  indebtedness  may  then  become
immediately  due  and  payable.  In  addition,  any  default  under  one  credit  agreement  could  lead  to  an  acceleration  of  debt  under  the  other
credit agreement pursuant to cross-acceleration or cross-default provisions. If the debt under either credit agreement is accelerated, we may
not have sufficient funds to make the accelerated payments, in which case we would be required to seek additional funds through various
financing sources, most likely through the sale of our equity or debt securities. However, there can be no assurance that such funds will be
available  on  commercially  reasonable  terms,  if  at  all.  Further,  any  sale  of  our  equity  or  equity-linked  securities  will  result  in  additional
dilution to our stockholders.

Our  outstanding  debt  may  make  it  difficult  for  us  obtain  additional  financing  using  our  future  operating  cash  flow.  We
currently have a substantial amount of indebtedness, including approximately $9.8 million owed to  Green  Bank  and  approximately  $6.0
million  owed  to  Interstate  Battery  as  of  the  date  of  this  prospectus  supplement.  Such  indebtedness  could  limit  our  ability  to  borrow
additional funds to fund operations or expansion or increase the cost of any such borrowing, or both. Our inability to conduct additional
debt financing could:

● limit our flexibility in developing our business operations and planning for, or reacting to, changes in our business;

 12

 
 
 
 
 
 
 
● increase our vulnerability to, and reduce our flexibility to respond to, general adverse economic and industry conditions; and

● place us at a competitive disadvantage as compared to our competitors that are not as highly leveraged.

Any of these or other consequences or events could have a material adverse effect on our ability to finance our business and our operations.

Our business model is new and has not been proven by us or anyone else. We are engaged in the business of producing recycled
lead through a novel and unproven technology. While the production of recycled lead is an established business, to date all recycled lead
has  been  produced  by  way  of  traditional  smelting  processes.  To  our  knowledge,  no  one  has  successfully  produced  recycled  lead  in
commercial  quantities  other  than  by  way  of  smelting.  In  addition,  our  lead  recycling  production  line  at  TRIC  is  the  first-of-its-kind  and
neither we nor anyone else has ever successfully built a production line that commercially recycles LABs without smelting. While we have
commenced limited lead recycling operations at our TRIC facility, to date all revenues have been derived from the sale of lead compounds
and plastics and we have not commenced the commercial production of AquaRefined lead. In addition to the general risks associated with a
novel and unproven technology, our business model is subject to a number of related risks, including:

● our ability to acquire sufficient quantities of used LABs at competitive prices;

● our ability to produce AquaRefined lead on a commercial scale and at an adequate gross profit; and

● our ability to sell our AquaRefined lead at prices and in quantities that provide an adequate net profit from operations.

Further,  there  can  be  no  assurance  that  we  will  be  able  to  produce  AquaRefined  lead  in  commercial  quantities  at  a  cost  of
production  that  will  provide  us  with  an  adequate  profit  margin.  The  uniqueness  of  our AquaRefining  process  and  our  production  line  at
TRIC presents potential risks associated with the development of a business model that is untried and unproven.

Certain  industry  participants  may  have  the  ability  to  restrict  our  access  to  used  LABs  and  otherwise  focus  significant
competitive  pressure  on  us.  We  believe  that  our  primary  competition  will  come  from  operators  of  existing  smelters  and  other  parties
invested  in  the  existing  supply  chain  for  smelting,  both  of  which  may  resist  the  change  presented  by  our  AquaRefining  process.
Competition from such incumbents may come in the form of restricted access to used LABs. We believe that LAB manufacturers who also
maintain  their  own  smelting  operations  control  a  significant  part  of  the  market  for  used  LABs.  We  will  require  access  to  used  LABs  at
market prices in order to carry out our business plan. If those LAB manufacturers and others involved in the reverse supply chain for used
LABs attempt to restrict our access to used LABs, that may adversely affect our prospects and future growth. There can be no assurance
that we will be able to effectively withstand the pressures applied by our competition.

Even if we are successful in recycling lead using our processes, there can be no assurance that the AquaRefined lead will meet
the certification and purity requirements of our potential customers. A key component of our business plan is to produce recycled lead
through our AquaRefining process of the highest purity (at least 99.99% pure lead), which we refer to as AquaRefined lead. We believe
that our AquaRefined lead will provide us with the highest gross profit margin and, more importantly, our ability to produce AquaRefined
lead will be vital to confirming the efficacy and relevancy of our proprietary technology. Our customers will require that our AquaRefined
lead meet certain minimum purity standards and, in all likelihood, require independent assays to confirm the lead’s purity. As of the date of
this report, we have produced limited quantities of AquaRefined lead. However, we have not produced AquaRefined lead in commercial
quantities  and  there  can  be  no  assurance  that  we  will  be  able  to  do  so  or,  if  we  are  able  to  produce AquaRefined  lead  in  commercial
quantities, that such lead will meet the required purity standards of our customers. If we are unable to commercially produce AquaRefined
lead that meets the purity standards established by our customers, our entire business plan may be invalidated and you may suffer the loss
of your entire investment.

While we have been successful in producing AquaRefined lead in small volumes, there can be no assurance that we will be able
to replicate the process, along with all of the expected economic advantages, on a large commercial scale. As of the date of this report,
our commercial operations have involved the production of lead compounds and plastics from recycled LABs and we have not commenced
the  commercial  production  of  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 lead. There can be no assurance that the commencement of commercial production of AquaRefined
lead at our TRIC facility will not incur unexpected costs or setbacks that might restrict the desired scale of our intended operations or that
we  will  be  to  produce AquaRefined  lead  in  commercial  quantities  at  a  cost  of  production  that  will  provide  us  with  an  adequate  profit
margin.

We  have  completed  the  construction  of  our  initial  LAB  recycling  facility  at  TRIC,  however  we  have  been  delayed  in  the
completion of our lead recycling operations at TRIC and we may encounter further delays. We completed the construction of our initial
LAB  recycling  facility  at  TRIC  in August  2016  and  commenced  the  limited  production  of  recycled  lead  in  the  first  quarter  of  2017.
However,  as  of  the  date  of  this  report,  our  commercial  operations  have  involved  the  production  of  lead  compounds  and  plastics  from
recycled LABs and we have not commenced the commercial production of AquaRefined lead. As of December 2017, we have installed 16
AquaRefining modules. However, we encountered an issue which required the retrofitting of all 16 modules. As of the date of this report,
we expect to complete the retrofit of all 16 modules by late March or early April and to begin to bring all 16 modules into commercial
operation. However, due to the delays and unforeseen issues in the completion of the AquaRefining production line we have experienced to
date, there can be no assurance that we will not encounter additional delays and issues. In addition, since our lead recycling production line
at TRIC is the first-of-its-kind, neither we nor anyone else has ever built a facility of this nature and there can be no assurance that we will
not  experience  continuing  operational  delays  and  issues,  including  significant  downtime  from  time  to  time,  as  we  progress  into  the
commercial production of AquaRefined lead. There can be no assurance that the commencement of commercial AquaRefining operations
at our TRIC facility will not incur unexpected costs or hurdles that might restrict the desired scale of our intended operations or negatively
impact our projected gross profit margin.

Our  intellectual  property  rights  may  not  be  adequate  to  protect  our  business. As  of  the  date  of  this  report,  we  have  secured
international  patents  in  Korea  (Korea  Patent  No.  10-1739414),  Japan  (Japan  Patent  No.  6173595)  Australia  (Australia  Patent  No.
AU2014353227), United States (US 9837689), and South Africa (ZA 2016.04083), and secured allowance in Canada (CA 2930945). We
also have further patent applications pending in the United States and numerous corresponding patent applications pending in 20 additional
jurisdictions  relating  to  certain  elements  of  the  technology  underlying  our  AquaRefining  process  and  related  apparatus  and  chemical
formulations.  However,  no  assurances  can  be  given  that  any  patent  issued,  or  any  patents  issued  on  our  current  and  any  future  patent
applications, will be sufficiently broad to adequately protect our technology. In addition, we cannot assure you that any patents issued now
or in the future will not be challenged, invalidated, or circumvented.

Even patents issued to us may not stop a competitor from illegally using our patented processes and materials. In such event, we

would incur substantial costs and expenses, including lost time of management in addressing and litigating, if necessary, such matters.
Additionally, we rely upon a combination of trade secret laws and nondisclosure agreements with third parties and employees having
access to confidential information or receiving unpatented proprietary know-how, trade secrets and technology to protect our proprietary
rights and technology. These laws and agreements provide only limited protection. We can give no assurance that these measures will
adequately protect us from misappropriation of proprietary information.

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

Our business strategy includes licensing arrangements and entering into joint ventures and strategic alliances, however as of
the  date  of  this  report  we  have  no  such  agreements  in  place  and  there  can  be  no  assurance  we  will  be  able  to  do  so.  Failure  to
successfully integrate such licensing arrangements, joint ventures, or strategic alliances into our operations could adversely affect our
business. We propose to commercially exploit our AquaRefining process, in part, by licensing our technology to third parties and entering
into joint ventures and strategic relationships with parties involved in the manufacture and recycling of LABs, including Johnson Controls,
among  others.  However,  as  of  the  date  of  this  report,  we  have  not  entered  into  any  such  licensing,  joint  venture  or  strategic  alliance
agreements, apart from our equipment supply agreement with Johnson Controls, and there can be no assurance that we will be able to do so
on terms that benefit us, if at all. In addition, licensing programs, joint ventures and strategic alliances may involve significant other risks
and uncertainties, including distraction of management’s attention away from normal business operations, insufficient revenue generation
to  offset  liabilities  assumed  and  expenses  associated  with  the  transaction,  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.

There  can  be  no  assurance  that  we  will  be  able  to  negotiate  our  key  agreement  with  Johnson  Controls  on  commercially
reasonable terms, or at all. In February 2017, we entered into a series of agreements with Johnson Controls, including an equipment supply
agreement  pursuant  to  which,  among  other  things,  we  agreed  to  work  with  Johnson  Controls  on  the  development  of  a  program  for  the
conversion of Johnson Controls and certain strategic partners of Johnson Controls’ existing lead smelters throughout North America, China
and  Europe  to  a  lead  recycling  process  utilizing  our AquaRefining  technology  and  equipment,  know-how  and  services.  The  equipment
supply agreement discusses the development of the conversion program in general terms and contemplates that the parties will enter into a
definitive  development  program  agreement  that  is  based  on  the  general  terms  set  forth  in  the  equipment  supply  agreement  and  provides
more  detailed  terms  and  conditions,  including  the  economic  obligations  and  rights  of  each  party.  We  have  agreed  not  to  license  our
AquaRefining technology and equipment to third parties in the aforementioned regions until such time as we and Johnson Controls have
agreed on certain matters relating to the initial conversion of a Johnson Controls facility. Johnson Controls and we have agreed to use good
faith,  commercial  best-efforts  to  conclude  the  discussion  and  negotiation  of  the  development  program  agreement  no  later  than April  30,
2018, and to enter into a definitive development program agreement no later than June 30, 2018. The equipment supply agreement may be
terminated by either party upon 60 days’ prior written notice if the parties have not entered into the development program agreement by
June 30, 2018. There can be no assurance that we will be able to negotiate and conclude a definitive development program agreement with
Johnson Controls on commercially reasonable terms, or at all.

We are dependent on a limited number of suppliers of certain materials used in our AquaRefining process and our inability to
obtain these materials as and when needed could cause a material disruption in our operations. Our AquaRefining process involves a
significant number of elements, chemicals, solvents and other materials, in addition to used LABs. There are a limited number of suppliers
of certain materials used in our AquaRefining process and we have no agreements in place for our supply of such materials. Our ability to
conduct  our AquaRefining  process  on  a  commercial  scale  will  depend  significantly  on  obtaining  timely  and  adequate  supply  of  these
materials on competitive terms. Our inability to source these materials on a timely and cost-efficient manner could interrupt our operations,
significantly limit our revenue sales and increase our costs. This factor could also impair our ability to meet our commitments to supply our
customers. Our inability to obtain these materials as and when needed could cause a material disruption in our operations.

If  we  are  unable  to  manage  future  expansion  effectively,  our  business,  operations  and  financial  condition  may  suffer
significantly, resulting in decreased productivity. If our AquaRefining process proves to be commercially viable, growth and expansion
activities could place a significant strain on our managerial, administrative, technical, operational and financial resources. Our organization,
procedures and management may not be adequate to fully support the expansion of our operations or the efficient execution of our business
strategy. If we are unable to manage future expansion effectively, our business, operations and financial condition may suffer significantly,
resulting in decreased productivity.

Certain  industry  participants  may  have  the  ability  to  restrict  our  access  to  used  LABs  and  otherwise  focus  significant
competitive  pressure  on  us. We  believe  that  our  primary  competition  will  come  from  operators  of  existing  smelters  and  other  parties
invested  in  the  existing  supply  chain  for  smelting,  both  of  which  may  resist  the  change  presented  by  our  AquaRefining  process.
Competition from such incumbents may come in the form of restricted access to used LABs. We believe that LAB manufacturers who also
maintain their own smelting operations control approximately 50% of the market for used LABs. We will require access to used LABs at
market prices in order to carry out our business plan. If those LAB manufacturers and others involved in the reverse supply chain for used
LABs attempt to restrict our access to used LABs that may adversely affect our prospects and future growth. There can be no assurance that
we will be able to effectively withstand the pressures applied by our competition.

We may experience significant fluctuations in raw material prices and the price of our principal product, either of which could
have a material adverse effect on our liquidity, growth prospects and results of operations. Used LABs are our primary raw material and
we believe that in recent years the cost of used LABs has been volatile at times. In addition, we believe that the cost of used LABs can be
seasonal, with prices trending lower in the winter months (as automobile owners increase their purchase of new LABs, thereby putting a
greater  number  of  used  LABs  on  the  market)  and  trend  higher  in  the  spring  (as  the  purchase  of  new  LABs,  and  supply  of  used  LABs,
decreases). Our principal product, recycled lead, has also experienced price volatility from time to time as well. For example, the market
price  of  lead  on  the  London  Metal  Exchange,  or  LME,  during  2017  ranged  from  approximately  $2,000  to  $2,600  per  tonne.  While  we
intend to pursue supply and tolling arrangements as appropriate to offset any price volatility, the volatile nature of prices for used LABs and
recycled lead could have an adverse impact on our liquidity, growth prospects and 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 our principal product, recycled lead, is relatively volatile and reacts to
general  global  economic  conditions.  Lead  prices  decreased  from  $2,139  per  tonne  on  May  5,  2015  to  a  low  of  $1,554  per  tonne  on
November 23, 2015 because of fluctuations in the market. A month later, the price per tonne increased back up to $1,801 per tonne; the
price per tonne was $2,495 on December 31, 2017. Our business will be highly dependent on the economic and market conditions in each
of the geographic areas in which we operate. These conditions affect our business by reducing the demand for LABs and decreasing the
price of lead in times of economic down turn and increasing the price of used LABs in times of increasing demand of LABs and recycled
lead. There can be no assurance that global economic conditions will not negatively impact our liquidity, growth prospects and results of
operations.

We are subject to the risks of conducting business outside the United States. A part of our strategy involves our pursuit of growth
opportunities in certain international market locations. We intend to pursue licensing or joint venture arrangements with local partners who
will be primarily responsible for the day-to-day operations. Any expansion outside of the US will require significant management attention
and financial resources to successfully develop and operate any such facilities, including the sales, supply and support channels, and we
cannot assure you that we will be successful or that our expenditures in this effort will not exceed the amount of any resulting revenues.
Our international operations expose us to risks and challenges that we would otherwise not face if we conducted our business only in the
United States, such as:

● increased cost of enforcing our intellectual property rights;

● 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;

● foreign currency fluctuations;

● laws favoring local competitors;

● weaker legal  protections  of  contract  terms,  enforcement  on  collection  of  receivables  and  intellectual property  rights  and

mechanisms for enforcing those rights;

● market disruptions created by public health crises in regions outside the United States;

● difficulties in staffing and managing foreign operations, including challenges presented by relationships with workers’ councils

and labor unions;

● issues related to differences in cultures and practices; and

● changing regional economic, political and regulatory conditions.

U.S. Government regulation and environmental, health and safety concerns may adversely affect our business. Our operations
in the United States will be subject to the Federal, State and local environmental, health and safety laws applicable to the reclamation of
lead  acid  batteries.  Our  facilities  will  have  to  obtain  environmental  permits  or  approvals  to  operate,  including  those  associated  with  air
emissions, water discharges, and waste management and storage. We may face opposition from local residents or public interest groups to
the installation and operation of our facilities. In addition to permitting requirements, our operations are subject to environmental health,
safety  and  transportation  laws  and  regulations  that  govern  the  management  of  and  exposure  to  hazardous  materials  such  as  the  lead  and
acids  involved  in  battery  reclamation.  These  include  hazard  communication  and  other  occupational  safety  requirements  for  employees,
which may mandate industrial hygiene monitoring of employees for potential exposure to lead. 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.

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.

The  development  of  new  AquaRefining  facilities  by  us  or  our  partners  or  licensees,  and  the  expansion  of  our  operations  at
TRIC, will depend on our ability to acquire necessary permits and approvals, of which there can be no assurance. As noted above, our
AquaRefining facilities 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  our  planned  expansion  of AquaRefining  operations  at
TRIC  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  facilities  or  expanding  operations  at
TRIC,  and  otherwise  adversely  affect  our  business,  financial  results  and  growth  prospects.  Further,  the  loss  of  any  necessary  permit  or
approval could result in the closure of an AquaRefining facility and the loss of our investment associated with such facility.

Our business involves the handling of hazardous materials and we may become subject to significant fines and other liabilities
in the event we mishandle those materials. The nature of our operations involves risks, including the potential for exposure to hazardous
materials  such  as  lead,  that  could  result  in  personal  injury  and  property  damage  claims  from  third  parties,  including  employees  and
neighbors,  which  claims  could  result  in  significant  costs  or  other  environmental  liability.  Our  operations  also  pose  a  risk  of  releases  of
hazardous  substances,  such  as  lead  or  acids,  into  the  environment,  which  can  result  in  liabilities  for  the  removal  or  remediation  of  such
hazardous substances from the properties at which they have been released, liabilities which can be imposed regardless of fault, and our
business could be held liable for the entire cost of cleanup even if we were only partially responsible. We are also subject to the possibility
that  we  may  receive  notices  of  potential  liability  in  connection  with  materials  that  were  sent  to  third-party  recycling,  treatment,  and/or
disposal  facilities  under  the  Federal  Comprehensive  Environmental  Response,  Compensation  and  Liability  Act  of  1980,  as  amended
(“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 US, or they could be less stringent or not as strictly
enforced. In some countries in which we are interested in expanding our business, such as Mexico and China, the relevant environmental
regulatory and enforcement frameworks are in flux and subject to change. 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

Securities class action lawsuits and shareholder derivative lawsuit are pending against us and could have a material adverse
effect  on  our  business,  results  of  operations  and  financial  condition. Three  putative  class  action  lawsuits  and  shareholder  derivative
lawsuit are pending against us and certain of our directors and officers. These lawsuits may divert financial and management resources that
would otherwise be used to benefit our operations. Although we deny the material allegations in the lawsuits and intend to defend ourselves
vigorously,  defending  the  lawsuits  could  result  in  substantial  costs.  No  assurances  can  be  given  that  the  results  of  these  matters  will  be
favorable  to  us. An  adverse  resolution  of  any  of  these  lawsuits  could  have  a  material  adverse  effect  on  our  results  of  operations  and
financial condition. In addition, we may be the target of securities-related litigation in the future, both related and unrelated to the existing
class action and shareholder derivative lawsuits. Such litigation could divert our management’s attention and resources, result in substantial
costs, and have an adverse effect on our business, results of operations and financial condition.

We maintain director and officer insurance that we regard as reasonably adequate to protect us from potential claims; however, we
cannot  assure  you  that  it  will.  Further,  as  a  result  of  the  pending  litigation  the  costs  of  insurance  may  increase  and  the  availability  of
coverage may decrease. As a result, we may not be able to maintain our current levels of insurance at a reasonable cost, or at all, which
might make it more difficult to attract qualified candidates to serve as executive officers or directors.

Our common stock is thinly traded and our share price has been volatile. Our common stock has traded on the Nasdaq Capital
Market, under the symbol “AQMS”, since July 31, 2015. Since that date, our common stock has at times been relatively thinly traded and
subject to price volatility. There can be no assurance that we will be able to successfully maintain a liquid market for our common shares.
The stock market in general, and early stage public companies in particular, has experienced extreme price and volume fluctuations that
have often been unrelated or disproportionate to the operating performance of such companies. If we are unable to develop and maintain a
liquid market for our common shares, you may not be able to sell your common shares at prices you consider to be fair or at times that are
convenient for you, or at all. In addition, following periods of volatility in the market price of a company’s securities, litigation has often
been  brought  against  that  company  and  we  may  become  the  target  of  litigation  as  a  result  of  price  volatility.  Litigation  could  result  in
substantial costs and divert our management’s attention and resources from our business. This could have a material adverse effect on our
business, results of operations and financial condition.

We  are  an  “emerging  growth  company”  under  the  JOBS  Act  of  2012  and  we  cannot  be  certain  if  the  reduced  disclosure
requirements applicable to emerging growth companies will make our common stock less attractive to investors. We are an “emerging
growth  company,”  as  defined  in  the  Jumpstart  Our  Business  Startups Act  of  2012  (“JOBS Act”),  and  we  may  take  advantage  of  certain
exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies”
including, but not limited to:

● not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act;

● reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements;

● exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval

of any golden parachute payments; and

● extended transition periods available for complying with new or revised accounting standards.

We have chosen to “opt out” of the extended transition periods available for complying with new or revised accounting standards,
but we intend to take advantage of all of the other benefits available under the JOBS Act, including the exemptions discussed above. We
cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our
common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more
volatile.

We  will  remain  an  “emerging  growth  company  until  2020,  although  we  will  lose  that  status  sooner  if  our  revenues  exceed  $1
billion, if we issue more than $1 billion in non-convertible debt in a three-year period, or if the market value of our common stock that is
held by non-affiliates exceeds $700 million as of any June 30.

Our status as an “emerging growth company” under the JOBS Act may make it more difficult to raise capital as and when we
need it. Because of the exemptions from various reporting requirements provided to us as an “emerging growth company,” we may be less
attractive to investors and it may be difficult for us to raise additional capital as and when we need it. Investors may be unable to compare
our business with other companies in our industry if they believe that our reporting is not as transparent as other companies in our industry.
If we are unable to raise additional capital as and when we need it, our financial condition and results of operations may be materially and
adversely affected.

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 develop our recycling centers 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.

Shares eligible for future sale may adversely affect the market for our common stock . Of the 28,694,210 shares of our common
stock outstanding as of the date of this annual report, approximately 25,699,794 shares are held by “non-affiliates” and are freely tradable
without  restriction  pursuant  to  Rule  144.  In  addition,  in August  2016,  we  filed  with  the  SEC  a  Registration  Statement  on  Form  S-3  for
purposes  of  registering  the  resale  of  3,711,872  shares  of  restricted  common  stock  sold  to  Interstate  Battery  in  May  2016,  including
3,009,625 shares of common stock issuable to Interstate Battery upon exercise of its warrants and conversion of its convertible note, and in
February 2017, we filed with the SEC a Registration Statement on Form S-3 for purposes of registering the resale of the 939,005 shares of
restricted common stock we sold to Johnson Controls in February 2017. Both registration statements were declared effective by the SEC
and the shares registered thereunder are eligible for sale without restriction. Any substantial sale of our common stock pursuant to Rule 144
or pursuant to any resale prospectus may have a material adverse effect on the market price of our common stock.

Our  charter  documents  and  Delaware  law  may  inhibit  a  takeover  that  stockholders  consider  favorable.  Provisions  of  our
certificate of incorporation and bylaws and applicable provisions of Delaware law may delay or discourage transactions involving an actual
or  potential  change  in  control  or  change  in  our  management,  including  transactions  in  which  stockholders  might  otherwise  receive  a
premium  for  their  shares,  or  transactions  that  our  stockholders  might  otherwise  deem  to  be  in  their  best  interests.  The  provisions  in  our
certificate of incorporation and bylaws:

● limit who may call stockholder meetings;

● do not permit stockholders to act by written consent;

● do not provide for cumulative voting rights; 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 our directors, officers or other employees.

Legal Proceedings

Beginning  on  December  15,  2017,  three  purported  class  action  lawsuits  were  filed  in  the  United  Stated  District  Court  for  the
Northern District California against us, Stephen R. Clarke, Thomas Murphy and Mark Weinswig: Arlis Hampton vs. Aqua Metals, Inc. et
al., Case No 3:17-cv-07142; Grant Heath vs. Aqua Metals, Inc. et al., Case No 3:17-cv-07196-JST; Lotfy Arbab vs. Aqua Metals, Inc. et al.,
Case  No  3:17-cv-07270WHA.  Each  of  the  complaints  was  filed  by  persons  claiming  to  be  stockholders  of Aqua  Metals  and  generally
allege violations of the anti-fraud provisions of the federal securities laws based on the alleged issuance of false and misleading statements
of material fact, and the alleged omission to state material facts necessary to make other statements made not misleading, between May 19,
2016  and  November  9,  2017  with  respect  to  our  lead  recycling  operations.  The  complaints  seek  unspecified  damages  and  plaintiffs’
attorneys’ fees and costs. As of the date of this report, multiple plaintiffs have filed motions seeking appointment as lead plaintiff. Briefing
on those competing motions was completed in early March, and a hearing is set for May 17, 2018. We have not filed a responsive pleading
in any of the above actions and do not expect to do so until a lead plaintiff has been appointed by the Court. We deny that the claims in any
of the complaints have any merit and we intend to vigorously defend the actions.

Beginning on February 2, 2018, two purported shareholder derivative actions were filed in the United States District Court for the
District  of  Delaware  against  us  and  our  current  executive  officers  and  directors,  Stephen  R.  Clarke,  Selwyn  Mould,  Mark  Weinswig,
Vincent DiVito, Mark Slade and Mark Stevenson, and one former officer and director, Thomas Murphy:  Al Lutzker, Derivatively and on
Behalf  of  Aqua  Metals,  Inc.  v.  Stephen  R.  Clarke,  Thomas  Murphy,  Mark  Weinswig,  Selwyn  Mould,  Vincent  L.  Divito,  Mark  Slade  and
Mark Stevenson and Aqua Metals, Inc., Case No. 1:99-mc-09999; and Chau Nguyen, Derivatively and on Behalf of Aqua Metals, Inc. v.
Stephen R. Clarke, Thomas Murphy, Mark Weinswig, Selwyn Mould, Vincent L. Divito, Mark Slade and Mark Stevenson and Aqua Metals,
Inc., Case No. 1:18-cv-00327. The complaints were filed by persons claiming to be stockholders of Aqua Metals and generally alleges that
certain of our officers and directors breached their fiduciary duties to us by violating the federal securities laws and exposing us to possible
financial liability. The complaints seek unspecified damages and plaintiffs’ attorneys’ fees and costs. As of the date of this report, we have
not filed a responsive pleading in either action. We deny that the claims in the shareholder derivative action have any merit and we intend to
vigorously defend the action.

We are not party to any other legal proceedings. We may, from time to time, be party to litigation and subject to claims incident to
the ordinary course of business. As our growth continues, we may become party to an increasing number of litigation matters and claims.
The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect our
future financial position, results of operations or cash flows.

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

General

Aqua Metals (NASDAQ: AQMS) is reinventing lead recycling with its proprietary AquaRefining ™ technology. AquaRefining is a
room temperature, water-based process that is fundamentally non-polluting. Our AquaRefining modular systems allow the lead-acid battery
industry  to  simultaneously  improve  environmental  impact  and  scale  recycling  production  to  meet  demand.  Aqua  Metals  is  based  in
Alameda, California, and has built its first recycling facility in Nevada’s Tahoe Reno Industrial Complex. We were formed as a Delaware
corporation on June 20, 2014 and since our formation, we have focused our efforts on the development and testing of our AquaRefining
process,  the  construction  of  our  initial  lead  acid  battery,  or  LAB,  recycling  facility  in  the  Tahoe  Regional  Industrial  Center,  McCarran,
Nevada  (“TRIC”),  the  continuing  development  of  our  LAB  recycling  operations  at  TRIC  as  we  bring  those  LAB  recycling  operations
online.

We have completed the building construction of our first LAB recycling facility at TRIC and commenced production during the first
quarter of 2017. The TRIC facility will produce recycled lead, consisting of lead compounds, ingoted hard lead and ingoted AquaRefined
lead as well as plastic. We commenced the shipment of products for sale, consisting of lead compounds and plastics, in April 2017 and to
the date of this report all revenue has been derived from the sale of lead compounds and plastics.

By December 2017, we had installed 16 AquaRefining modules. However, we encountered an issue which required the retrofitting
of all 16 modules. As of the date of this report, we expect to complete the retrofit of all 16 modules by late March or early April and to
begin  to  bring  all  16  modules  into  commercial  operation.  However,  due  to  the  delays  and  unforeseen  issues  in  the  completion  of  the
AquaRefining  production  line  we  have  experienced  to  date,  there  can  be  no  assurance  that  we  will  not  encounter  additional  delays  and
issues.

Since January 1, 2017, we have engaged in the following financing transactions:

Johnson  Controls  Investment.  In  connection  with  our  entry  into  the  equipment  supply  agreement  and  tolling/lead  purchase
agreement with Johnson Controls, on February 7, 2017 which we entered into a stock purchase agreement with Johnson Controls pursuant
to which we sold to Johnson Controls 939,005 shares of our common stock at $11.33 per share for the gross proceeds of approximately
$10.6  million.  We  granted  Johnson  Controls  customary  demand  and  piggyback  registration  rights,  limited  board  observation  rights  and
limited  preemptive  rights  allowing  it  to  purchase  its  proportional  share  of  certain  future  equity  issuances  by  us.  We  included  all  of  the
Johnson Controls shares in our Form S-3 Registration Statement filed with the Securities and Exchange Commission on February 27, 2017.

Public Offering.  On  December  12,  2017,  we  completed  a  public  offering  of  7,150,000  shares  of  our  common  stock,  at  the  public
offering price of $2.10 per share, for gross proceeds of $15 million. After the payment of underwriter discounts and offering expenses we
received net proceeds of approximately $13.8 million. In January 2018, the underwriter exercised their overallotment option resulting in an
additional 1,072,500 shares being issued and net proceeds to us of approximately $2.1 million.

Plan of Operations

Our plan of operations for 2018 is to complete the assembly and retro-fit of all 16 AquaRefining modules installed at TRIC and to
ramp up the production of AquaRefined lead during 2018. We plan to install an additional 16 AquaRefining modules to our TRIC facility,
subject  to  our  receipt  of  additional  capital  and  any  design  improvements  that  are  recommended  based  on  the  operation  of  the  first  16
modules.

Subject to our ability to ramp up our AquaRefining operations to a commercial scale, our priority will be to develop a proposal to
provide equipment, planning, engineering, technical and other services in support of the addition of an AquaRefining facility to a battery
recycling facility owned by Johnson Controls. This proposed work is expected to produce a blueprint for further additions of AquaRefining
facilities  under  a  proposed  definitive  development  agreement  with  Johnson  Controls.  Pursuant  to  that  definitive  agreement  we  plan  to
collaborate  with  Johnson  Controls  for  the  conversion  of  its  own  and  certain  of  its  strategic  partners’  existing  lead  smelters  to  a  lead
recycling  process  utilizing  our  proprietary  AquaRefining  technology,  equipment,  know-how  and  services.  However,  there  can  be  no
assurance that we will be able to conclude a definitive development agreement with Johnson Controls on terms that benefit us, if at all.

Our 12-month plan of operations includes the pursuit and evaluation of additional strategic relationships to support the expansion of

our own facilities and/or the provision of equipment and services to third parties.

 25

 
 
 
 
 
 
 
 
 
 
 
 
 
Additional  funding  will  be  required  to  increase  production  of AquaRefined  lead  at  TRIC  beyond  that  planned  for  16  modules,  to
work with Johnson Controls on equipment integration and licensing to third parties, to fund working capital needs related to the ramp-up of
our  operations  and  to  fund  our  continued  losses  from  operations  until  such  time  as  we  are  able  to  achieve  positive  cash  flow  from
operations.  We  intend  to  seek  additional  funds  through  various  financing  sources,  including  the  sale  of  our  equity  and  debt  securities,
licensing fees for our technology, joint ventures with capital partners and/or project financing of our recycling facilities. However, there can
be no guarantees that such funds will be available on commercially reasonable terms, if at all.

Results of Operations for the Fiscal Year Ended December 31, 2017 Compared to the Fiscal Year Ended December 31, 2016

We  were  formed  on  June  20,  2014  and  did  not  commence  revenue  producing  operations  until  January  2017.  During  the  second
quarter of 2017, we began shipments of lead compounds and plastics to customers. The following table summarizes results of operations
with respect to the items set forth below for the year ended December 31, 2017 and 2016 together with the percentage change in those items
(in thousands).

As mentioned above, product sales, consisting of lead compounds and plastics began in April 2017. Cost of product sales consists of
all operating costs incurred at TRIC following the commencement of product sales. Costs incurred at TRIC prior to commencement of sales
are  included  in  research  and  development  costs.  Cost  of  product  sales  includes  raw  materials,  supplies  and  related  costs,  salaries  and
benefits, consulting and outside services costs, depreciation and amortization costs and insurance, travel and overhead costs. There are no
comparatives for the previous periods.

Research and development cost included TRIC operating cost prior to the commencement of product sales, including cost incurred to
prepare our TRIC plant for operations. During the year ended December 31, 2017, research and development costs increased by 28% over
the comparable period in 2016. At December 31, 2016, we had 30 employees in the TRIC facility and we focused on building the plant
(cost included in research and development expense). At December 31, 2017, we had 41 employees at the TRIC facility and are focused on
recycling  lead  operations  as  well  as  continuing  to  commission  various  processes  within  the  plant  (cost  included  in  research  and
development  expense  until  product  sales  began,  at  which  point  forward  they  were  included  in  cost  of  product  sales).  The  increase  in
research and development cost during the year ended December 31, 2017 versus the prior period is due to increased level of operations and
commissioning of our plant in TRIC. We expect that research and development expenses will decrease from the current level going forward
as all the cost related to TRIC will be included in cost of product sales.

General  and  administrative  expense  has  been  relatively  consistent  during  the  years  ended  December  31,  2017  and  December  31,
2016. The small increase is primarily due to our $0.6 million accrual for estimated costs to resolve a claim of breach of a negative covenant
in our convertible loan agreement with Interstate Battery.

As described above in Note 6 to the Condensed Consolidated Financial Statements, in April 2017, we acquired all of the capital

shares of Ebonex IPR Limited for consideration of $2.5 million, consisting of cash, transaction costs and 123,776 shares of our common
stock. The principal asset of Ebonex IPR Limited consisted of a patent portfolio with an independent fair value of $112,000. Included in the
purchase were certain fixed assets that have been determined by management to have no immediate value and were not considered in the
valuation of Ebonex IPR.

Due to the fair value of the patent portfolio being significantly less than total consideration, the early development stage of the
technology acquired and the uncertainties inherent in research and development, we recorded a non-cash impairment charge of $2.4 million
during the year ended December 31, 2017.

Interest during the year ended December 31, 2017 relates primarily to the $5.0 million Interstate Battery convertible note and the
$10.0 million notes payable, amortization of debt issuance costs incurred in connection with both of these notes, as well as an accrual for
the USDA guarantee fee on the $10.0 million note to Green Bank. Interest relating to the $10.0 million notes payable during the year ended
December  31,  2016  and  2015  was  capitalized  as  part  of  the  building  cost  of  the  TRIC  facility  in  the  amount  of  $0.5  million  and  $0.1
million, respectively. Interest capitalization ceased upon completion of the building in November 2016.

The note discount associated with the Interstate Battery convertible note is being amortized using the effective interest method over
the three-year term of the note, maturing on May 24, 2019. Using the effective interest method results in higher expense in later periods.
Thus, non-cash interest expense associated with the note discount amortization was $0.4 million in 2017 and will be $2.0 million in 2018
and $2.6 million in 2019.

Results of Operations for the Fiscal Year Ended December 31, 2016 Compared to the Fiscal Year Ended December 31, 2015

Thru  December  31,  2016,  our  operations  consisted  of  the  development  and  limited  testing  of  our  AquaRefining  process,  the
development of our business plan, the raise of our working capital and the development of our initial lead acid battery, or LAB, recycling
facility near Reno, Nevada. The following table summarizes our results of operations with respect to the items set forth below for the years

Operations  and  development  costs  nearly  tripled  from  2015  to  2016.  The  increase  was  due  to  the  increased  level  of  operations
following the completion of our initial public offering in August 2015. Salary related expenses nearly tripled, commensurate with a nearly
three-fold increase in head-count for the year ended December 31, 2016 versus 2015. Our research and development expenses doubled for
the  year  ended  December  31,  2016  versus  2015,  corresponding  to  an  increase  in  developmental  activities  over  the  prior  year.  Other
increases  include  professional  services,  depreciation,  insurance,  travel  and  general  overhead  costs  due  to  our  increased  activities,
particularly with regards to staffing up our operations at TRIC.

General and administrative expense also increased significantly. Salary related expenses doubled for the year ended December 31,
2016 versus 2015, while average headcount increased by 31%. The primary contributors to the difference between headcount and overall
expense  is  an  increase  in  executive  compensation  (including  bonus)  of  $0.8  million  in  2016  versus  2015  and  an  increase  in  stock-based
compensation  expense  of  $0.6  million.  Professional  services  increased  by  approximately  $0.9  million  for  the  year  ended  December  31,
2016  versus  2015,  which  included  both  third-party  consulting  and  legal  fees  and  primarily  related  to  being  a  publicly  traded  company
during 2016 versus a private company during much of 2015. Professional fees during the year ended December 31, 2016 included a one-
time $0.2 million charge due to the modification of a previously issued stock option to a former member of our Board of Directors that
accelerated the vesting and waived the early termination of the option based upon the termination of his service to the Company due to his
death. The remaining increase was due to increased travel, insurance and general overhead costs due to our increased activities compared to
the prior year.

We  incurred  approximately  $5.8  million  of  expense  during  the  year  ended  December  31,  2015  relating  to  an  increase  in  the  fair
value of derivative liabilities related to our then-outstanding convertible notes and related financing warrants. The convertible notes were
converted at the time of our IPO in August 2015 and, at the same time the derivative liability associated with the financing warrant was
reclassified  to  additional  paid-in  capital.  Therefore,  there  was  no  expense  related  to  the  derivative  liabilities  during  the  year  ended
December 31, 2016. We incurred interest expense of approximately $1.1 million during the year ended December 31, 2015, related to our
convertible  notes,  which,  as  noted  above,  converted  at  the  time  of  our  IPO.  Interest  during  the  year  ended  December  31,  2016  related
primarily  to  interest  incurred  on  the  $5.0  million  Interstate  Battery  convertible  note  and  the  $10.0  million  notes  payable  as  well  as
amortization of debt issuance costs incurred in connection with both of these notes as well as an accrual for the USDA guarantee fee on the
$10.0 million note. Interest of $0.5 million and $0.1 million relating to the $10.0 million notes payable was capitalized during the years
ended December 31, 2016 and 2015, respectively, as part of the building cost of the TRIC facility until its completion, in early November
2016.

Liquidity and Capital Resources

As  of  December  31,  2017,  we  had  total  assets  of  $74.4  million  and  working  capital  of  $21.9  million,  and  in  January  2018  we
acquired  an  additional  $2.1  million  from  the  exercise  of  the  underwriter’s  overallotment  option  relating  to  our  December  2017  public
offering.

Net cash used in operating activities for the year ended December 31, 2017, 2016 and 2015 was $19.0 million, $11.1 million and
$1.5 million, respectively. Net cash used in operating activities during each of these periods consisted primarily of our net loss adjusted for
noncash items such as depreciation, amortization, stock-based compensation charges, and noncash charges related the impairment charge
(2017) and to the mark-to-market valuation of our derivative liabilities (2015), as well as net changes in working capital.

Net cash used in investing activities

Net  cash  used  in  investing  activities  for  the  year  ended  December  31,  2017,  2016  and  2015  was  $8.7  million,  $19.1  million  and
$25.0 million, respectively. Net cash used in investing activities during each of these periods consists primarily of purchases of fixed assets
related to the build out of our TRIC recycling facility in Nevada, net of changes in restricted cash, and, to a lesser extent, our corporate
headquarters during 2016.

Net cash provided by financing activities

Net cash provided by financing activities for the year ended December 31, 2017 primarily consisted of $13.8 million net proceeds
from the issuance of common stock in our December 2017 public offering, $10.5 million net proceeds from the issuance of common stock
to Johnson Controls and $1.1 million proceeds from the exercise of stock options partially offset by lease and debt payments.

Net cash provided by financing activities for the year ended December 31, 2016 primarily consisted of $21.5 million net proceeds
from the issuance of common stock in our November 2016 public offering; $9.1 million net proceeds from the issuance of common stock
to Interstate Battery and other investors through our placement agent, National Securities Corporation; and $4.9 million net proceeds from
the Interstate Battery convertible note.

Net cash provided by financing activities for the year ended December 31, 2015 primarily consisted of $32.9 million net proceeds

from our IPO and $9.3 million net proceeds from a loan from Green Bank.

As  of  the  date  of  this  report,  we  believe  that  our  working  capital  is  sufficient  to  fund  the  commissioning  and  commencement  of
commercial  operations  of  at  least  16 AquaRefining  modules  and  our  commercial  operations  at  TRIC  through,  at  least,  December  2018,
assuming  the  successful  commercial  rollouts  of  the  16 AquaRefining  modules.  However,  we  will  require  additional  capital  in  order  to
increase  production  of AquaRefined  lead  at  TRIC  beyond  that  planned  for  16  modules,  to  work  with  Johnson  Controls  on  equipment
integration and licensing to third parties, to fund working capital needs related to the ramp-up of our operations and to fund our continued
losses from operations until such time as we are able to achieve positive cash flow from operations. We intend to seek additional funds
through various financing sources, including the sale of our equity and debt securities, licensing fees for our technology, joint ventures with
capital partners and/or project financing of our recycling facilities. However, there can be no guarantees that such funds will be available on
commercially reasonable terms, if at all. 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. Additionally, Aqua Metals Reno, or AMR, was not in compliance with its the
minimum  debt  service  coverage  ratio  covenant  as  of  and  for  the  three-month  periods  ended  March  31,  June  30,  September  30,  and
December 31, 2017 on its loan from Green Bank. AMR received a waiver for the minimum debt service coverage ratio covenant for the
periods ended March 31, June 30, September 30, and December 31, 2017. While we expect to continue to receive waivers from Green Bank
for non-compliance with such covenant, there is no guarantee that we will receive such waivers. If Green Bank determines not to grant us a
waiver for non-compliance in the future, we would be in default of the loan and Green Bank would be able to accelerate the payment of all
amounts under the loan. In addition, a failure by Green Bank to provide us with the required waiver could also constitute a default under
our $5 million loan with Interstate Battery and allow it to accelerate the payment of all amounts thereunder.

As of the date of this report, Interstate Battery has raised a claim that we are in technical breach of a negative covenant under our $5
million  loan  from  Interstate  Battery.  The  claimed  breach  relates  to  our  failure  to  obtain  Interstate  Battery’s  prior  written  consent  to  our
acquisition of Ebonex IPR, Ltd. In the event we are unable to resolve the matter, Interstate Battery may declare a default under the loan
and attempt to accelerate the payment of all amounts thereunder. There can be no assurance we will be able to resolve the claim of breach
or that Interstate Battery will not declare a default under the loan and attempt to accelerate the payment of all amounts thereunder.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet financing arrangements.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial
statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The preparation of
our consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets
and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported
amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and
valuation of long-lived assets, the valuation of conversion features of convertible debt, valuation allowances for deferred tax assets, the
determination of estimated asset retirement obligations, the determination of stock option expense, and the determination of the fair value
of stock warrants issued. Our actual results could differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2 to the consolidated financial statements included in

Item 8 of this Annual Report on Form 10-K, we believe that the following accounting policies are the most critical to assist stockholders
and investors reading the consolidated financial statements in fully understanding and evaluating our financial condition and results of
operations.

Accounts receivable

We sell our products to large well-established companies and extend credit without requiring collateral, based on an ongoing

evaluation of the customer’s business prospects and financial condition. In the event that payment of a customer’s account receivable is
doubtful, we would reserve the receivable under an allowance for doubtful accounts.

Inventory

Inventory is stated as the lower of cost or net realizable value. Inventory cost is recorded on a first-in, first-out basis using the

weighted average method. Net realizable value is determined as the estimated selling price in the ordinary course of business, less
reasonably predictable costs of completion, disposal, and transportation.

Property and equipment

Property and equipment are stated at cost net of accumulated depreciation. Depreciation on property and equipment is calculated on
the straight-line basis over the estimated useful lives of the assets. Leasehold improvements are depreciated over the shorter of the life of
the asset or the remaining term of the lease.

Intangible and other long-lived assets

The  intangible  assets  consist  of  a  patent  application  contributed  to  us  by  five  founding  stockholders,  patent  applications  for
technology developed by us and trademark applications. The useful life of the intangible assets has been determined to be ten years and the
assets are being amortized. We periodically evaluate our intangible and other long-lived assets for indications that the carrying amount of
an asset may not be recoverable. In reviewing for impairment, we compare the carrying value of such assets to the estimated undiscounted
future cash flows expected from the use of the assets and their eventual disposition. When the estimated undiscounted future cash flows are
less than their carrying amount, an impairment loss is recognized equal to the difference between the assets’ fair value and their carrying
value.  In  addition  to  the  recoverability  assessment,  we  routinely  review  the  remaining  estimated  lives  of  our  long-lived  assets.  Any
reduction in the useful life assumption will result in increased depreciation and amortization expense in the period when such determination
is  made,  as  well  as  in  subsequent  periods.  We  evaluate  the  need  to  record  impairment  during  each  reporting  period.  No  impairment  has
been recorded. We determined that the estimated life of the intellectual property properly reflected the current remaining economic life of
the asset.

Asset retirement obligations

We record the fair value of estimated asset retirement obligations associated with tangible long-lived assets in the period incurred.
Retirement obligations associated with long-lived assets are those for which there is an obligation for closures and/or site remediation at the
end of the assets’ useful lives. These obligations are initially estimated based on discounted cash flow estimates and are accreted to full
value  over  time  through  charges  to  operating  expense.  In  addition,  asset  retirement  costs  are  capitalized  as  part  of  the  related  asset’s
carrying value and are depreciated on a straight-line basis over the assets’ respective useful lives.

 30

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Revenue Recognition

The Company records revenue recognition in accordance with ASC 606, Revenue from Contracts with Customers. ASC 606
provides a single comprehensive model for the recognition of revenue arising from contracts with customers and supersedes most current
revenue recognition guidance, including industry-specific guidance. It requires an entity to recognize revenue when the entity transfers
promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange
for those goods or services. ASC 606 creates a five-step model that requires entities to exercise judgment when considering the terms of
contract(s), which includes (1) identifying the contract(s) with the customer, (2) identifying the separate performance obligations in the
contract, (3) determining the transaction price, (4) allocating the transaction price to the separate performance obligations, and (5)
recognizing revenue as each performance obligation is satisfied. ASC 606 requires additional disclosure about the nature, amount, timing
and uncertainty of revenue and cash flows arising from customer contracts, including qualitative and quantitative information about
contracts with customers, significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a
contract.

Research and development

Research and development expenditures are expensed as incurred.

Income taxes

We  account  for  income  taxes  in  accordance  with  the  liability  method  of  accounting  for  income  taxes.  Under  the  liability  method,
deferred assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial
statement  carrying  amounts  of  assets  and  liabilities  and  their  respective  tax  bases.  The  provision  for  income  taxes  is  comprised  of  the
current tax liability and the changes in deferred tax assets and liabilities. We established a valuation allowance to the extent that it is more
likely than not that deferred tax assets will not be recoverable against future taxable income.

We  recognize  the  effect  of  uncertain  income  tax  positions  only  if  those  positions  are  more  likely  than  not  of  being  sustained.
Recognized  income  tax  positions  are  measured  at  the  largest  amount  that  is  greater  than  50%  likely  of  being  realized.  Changes  in
recognition or measurement are reflected in the period in which the change in judgment occurs.

Stock-based compensation

We recognize compensation expense for stock-based compensation in accordance with ASC 718 “Compensation – Stock
Compensation.” For employee stock-based awards, we calculate the fair value of the award on the date of grant using the Black-Scholes-
Merton method for stock options; the expense is recognized over the service period for awards to vest.

The estimation of stock-based awards that will ultimately vest requires judgment and to the extent actual results or updated estimates
differ from the original estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised. The Company
considers many factors when estimating expected forfeitures, including types of awards, employee class and historical experience.

Operating lease obligations

We lease our Alameda, California and Oakland, California spaces under non-cancelable operating leases, expiring in 2021 and 2018,
respectively.

Capital lease obligations

We financed certain of our lab equipment purchases through the use of capital leases. The lease terms are between 24 and 36 months with
an option to purchase the asset at the end of the lease term for $1.

Convertible debt

Our convertible debt bears interest at 11% per annum and both interest and payable are due at maturity on May 25, 2019. Interest is not
convertible. See Note 10 in the accompanying notes to the consolidated financial statements for further description.

Long-term debt

AMR entered into a $10,000,000 loan with Green Bank on November 3, 2015. The term of the loan is twenty-one years. For the first
twelve months only interest was payable; thereafter monthly payments of interest and principal are due. The interest rate adjusts on the first
day of each calendar quarter equal to the greater of six percent (6%) or two percent (2%) per annum above the minimum prime lending rate
charged by large U.S. money center commercial banks as published in the Wall Street Journal. See Note 12 in the accompanying notes to
the consolidated financial statements for further description.

Item 7A.

Quantitative and Qualitative Disclosures About Market Risk

We  do  not  enter  into  financial  instruments  for  trading  or  speculative  purposes.  Our  cash,  cash  equivalents  and  restricted  cash
balances as of December 31, 2017 consisted of cash and cash equivalents. Our primary exposure to market risk is interest expense related to
our debt with Green Bank. The interest rate on this loan adjusts on the first day of each calendar quarter equal to the greater of six percent
(6%)  or  two  percent  (2%)  per  annum  above  the  minimum  prime  lending  rate  charged  by  large  U.S.  money  center  commercial  banks  as
published by the Wall Street Journal.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Aqua Metals, Inc. and Subsidiaries (collectively the “Company”) as of
December 31, 2017 and 2016, the related consolidated statements of operations, stockholders’ equity, and cash flows, for each of the three
years in the period ended December 31, 2017, and the related notes (collectively referred to as the “financial statements”). In our opinion,
the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016,
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with
U.S. generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion
on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and
the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or
fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As
part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of
expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such
opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence
regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting
principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial
statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2015.

1.         Organization and Operations

AQUA METALS, INC.
Notes to Consolidated Financial Statements 

Aqua Metals, Inc. (the “Company”) was incorporated in Delaware and commenced operations on June 20, 2014 (inception). On
January 27, 2015, the Company formed two wholly-owned subsidiaries, Aqua Metals Reno, Inc. (“AMR”), and Aqua Metals
Operations, Inc. (collectively, the “Subsidiaries”), both incorporated in Delaware. The Company is reinventing lead recycling with its
patent-pending AquaRefiningTM technology. Unlike smelting, AquaRefining is a room temperature, water-based process that is
fundamentally non-polluting. These modular systems allow the lead-acid battery industry to simultaneously improve environmental
impact and scale production to meet demand. The Company intends to manufacture the equipment it has developed and pursue the
development of lead acid battery recycling facilities, both directly and through licensing or joint development arrangements. The
Company commenced the shipment of products for sale, consisting of lead compounds and plastics in April 2017 and to the date of
this report all revenue has been derived from the sale of lead compounds and plastics.

Liquidity and Management Plans

The  Company  completed  the  development  of  our  first  LAB  recycling  facility  at  the  Tahoe  Reno  Industrial  Center  (“TRIC”)  and
commenced production during the first quarter of 2017. The TRIC facility will produce recycled lead, consisting of lead compounds,
ingoted hard lead and ingoted AquaRefined lead as well as plastic.

The Company generated revenues of $2.1 million during 2017 and had net losses of $26.6 million, $13.6 million and $12.3 million
for the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, the Company’s cash balance was
$22.8  million.  The  Company  believes  that  its  working  capital  is  sufficient  to  fund  the  commissioning  and  commencement  of
commercial  operations  of  16  AquaRefining  modules  and  its  commercial  operations  at  TRIC  through,  at  least,  December  2018,
assuming the successful commercial rollouts of the 16 AquaRefining modules.

2.         Summary of Significant Accounting Policies

Basis of presentation and consolidation

The accompanying consolidated financial statements include those of Aqua Metals, Inc. and its subsidiaries, after elimination of all
intercompany accounts and transactions. We have 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,  the  valuation  of  conversion  features  of
convertible  debt,  valuation  allowances  for  deferred  tax  assets,  the  determination  of  fair  value  of  estimated  asset  retirement
obligations, the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results
could differ from those estimates.

Cash and cash equivalents

The  Company  considers  all  highly  liquid  instruments  with  original  or  remaining  maturities  of  ninety  days  or  less  at  the  date  of
purchase to be cash equivalents. The Company maintains its cash balances in large financial institutions. Periodically, such balances
may be in excess of federally insured limits.

Restricted cash

Restricted  cash  was  comprised  of  funds  held  in  escrow  at  Green  Bank  for  the  purpose  of  paying  for  the  construction  of  the  lead
recycling  plant  building  in  McCarran,  Nevada.  As  of  December  31,  2017,  the  building  was  complete  and  the  funds  had  been
dispersed.

40

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Accounts receivable

The Company sells 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,
2017, the Company believes that all receivables will be collected and, therefore, has not created any reserve for doubtful accounts.

Inventory

Inventory is stated as the lower of cost or net realizable value. Cost is recorded on a first-in, first-out basis using the weighted average
method. Net realizable value is determined as the estimated selling price in the ordinary course of business, less reasonably
predictable costs of completion, disposal, and transportation. The Company records a write-down, if necessary, to reduce the carrying
value of inventory to its net realizable value. The effect of these write-downs is to establish a new cost basis in the related inventory,
which is not subsequently written up.

Property and equipment

Property and equipment are stated at cost net of accumulated depreciation. Depreciation on property and equipment is calculated on
the straight-line basis over the estimated useful lives of the assets. Leasehold improvements are depreciated over the shorter of the
life of the asset or the remaining term of the lease.

Intangible and other long-lived assets

Intangible  assets  consist  of  a  patent  application  contributed  to  the  Company  by  five  founding  stockholders,  patent  applications  for
technology  developed  by  the  Company,  trademark  applications  and  a  patent  portfolio  acquired  during  2017.  The  useful  life  of  the
intangible assets 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 further described in Note 6, the Company recorded an impairment of $2.4 million on the acquisition
of the 2017 acquired patent portfolio. The Company determined that the estimated life of the intellectual property properly reflected
the current remaining economic life of the asset.

Asset retirement obligations

The Company records the fair value of estimated asset retirement obligations associated with tangible long-lived assets in the period
incurred. Retirement obligations associated with long-lived assets are those for which there is an obligation for closures and/or site
remediation at the end of the assets’ useful lives. These obligations are initially estimated based on discounted cash flow estimates
and are accreted to full value over time through charges to operating expense. In addition, asset retirement costs are capitalized as part
of the related asset’s carrying value and are depreciated on a straight-line basis over the assets’ respective useful lives.

Revenue Recognition

The Company records revenue recognition in accordance with ASC 606, Revenue from Contracts with Customers. ASC 606 provides
a single comprehensive model for the recognition of revenue arising from contracts with customers and supersedes most current
revenue recognition guidance, including industry-specific guidance. It requires an entity to recognize revenue when the entity
transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be
entitled in exchange for those goods or services. ASC 606 creates a five-step model that requires entities to exercise judgment when
considering the terms of contract(s), which includes (1) identifying the contract(s) with the customer, (2) identifying the separate
performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the separate
performance obligations, and (5) recognizing revenue as each performance obligation is satisfied. ASC 606 requires additional
disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including
qualitative and quantitative information about contracts with customers, significant judgments and changes in judgments and assets
recognized from costs incurred to obtain or fulfill a contract.

Research and development

Research and development expenditures are expensed as incurred.

Income taxes

The Company accounts for income taxes in accordance with the liability method of accounting for income taxes. Under the liability
method,  deferred  assets  and  liabilities  are  recognized  based  upon  anticipated  future  tax  consequences  attributable  to  differences
between financial statement carrying amounts of assets and liabilities and their respective tax bases. The provision for income taxes is
comprised  of  the  current  tax  liability  and  the  changes  in  deferred  tax  assets  and  liabilities.  The  Company  establishes  a  valuation
allowance to the extent that it is more likely than not that deferred tax assets will not be recoverable against future taxable income.

The  Company  recognizes  the  effect  of  uncertain  income  tax  positions  only  if  those  positions  are  more  likely  than  not  of  being
sustained.  Recognized  income  tax  positions  are  measured  at  the  largest  amount  that  is  greater  than  50%  likely  of  being  realized.
Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

Fair value measurements

The  carrying  amounts  of  cash  and  cash  equivalents,  accounts  receivable,  inventory,  prepaid  expenses  and  other  current  assets,
accounts payable, accrued expenses and deferred rent approximate fair value due to the short-term nature of these instruments. The
carrying value of short and long-term debt also approximates fair value since these instruments bear 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 far 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, 2017 or 2016.

Stock-based compensation

The Company recognizes compensation expense for stock-based compensation in accordance with ASC 718 “Compensation – Stock
Compensation.” For employee stock-based awards, the Company calculates the fair value of the award on the date of grant using the
Black-Scholes-Merton method for stock options; the expense is recognized over the service period for awards to vest.

The estimation of stock-based awards that will ultimately vest requires judgment and to the extent actual results or updated estimates
differ from the original estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised.

Net loss per share

Basic net loss per share is computed by dividing net loss by the weighted average number of vested shares outstanding during the
period. Diluted net loss per share is computed by giving effect to all potential dilutive common securities, including convertible notes,
options and warrants. Potential dilutive common shares include the dilutive effect of the common stock underlying in-the-money
stock options and is calculated based on the average share price for each period using the treasury stock method. Under the treasury
stock method, the exercise price of an option and the average amount of compensation cost, if any, for future services that the
Company has not yet recognized when the option is exercised, are assumed to be used to repurchase shares in the current period.

For all periods presented in this report, convertible notes, stock options, and warrants were not included in the computation of diluted
net loss per share because such inclusion would have had an antidilutive effect.

Segment and Geographic Information

Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial
information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in
assessing performance. The Company views its operations and manages its business in one operating segment, and the Company
operates in only one geographic segment.

Concentration of Credit Risk

Substantially all of our revenue and accounts receivable as of and for the year ended December 31, 2017 is attributable to Johnson
Controls Battery Group, Inc. Substantially all of the chemicals used in our refining process are provided by one supplier and supply
of used lead acid batteries has, during 2017, been provided by two vendors supplying 56% and 44%, respectively.

Recent accounting pronouncements

In February 2016, the FASB issued ASU 2016-02 - Leases (ASC 842), which sets out the principles for the recognition,
measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors).  The new standard requires
lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the
lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on
an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a
right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases
with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today.  ASC 842 supersedes
the previous leases standard, ASC 840 Leases. The standard is effective on January 1, 2019, with early adoption permitted. The
Company is in the process of evaluating the impact of this new guidance.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash, or ASU 2016-18. The amendments in ASU 2016-18
require an entity to reconcile and explain the period-over-period change in total cash, cash equivalents and restricted cash within its
statements of cash flows. ASU 2016-18 is effective for fiscal years, and interim periods within, beginning after December 15, 2017.
Early adoption is permitted. A reporting entity must apply the amendments in ASU 2016-18 using a full retrospective approach. The
Company is currently evaluating the impact the adoption of the ASU will have on its consolidated financial statements.

3.         Revenue recognition

Revenues are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the
consideration the Company expects to be entitled to in exchange for those goods or services. Generally, this occurs with the delivery
of the Company’s products, primarily hard lead, lead compounds and plastics, to customers. Sales, value add, and other taxes, if any,
that are collected concurrent with revenue-producing activities are excluded from revenue as they are subsequently remitted to
governmental authorities. Incidental items that are immaterial in the context of the contract are recognized as expense. Freight and
shipping costs related to the transfer of the Company’s products to customers are included in revenue and cost of product sales.
Payment on invoices is generally due within 30 days of the invoice.

The Company generates revenues by recycling lead acid batteries (“LABs”) and selling the recovered lead to its customers. Primary
components of the recycling process include sales of recycled lead consisting of lead compounds, ingoted hard lead and ingoted
AquaRefined lead as well as plastics. The Company commenced the shipment of products for sale, consisting of lead compounds and
plastics in April 2017 and to the date of this report all revenue has been derived from the sale of lead compounds and plastics.

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.

Revenue from products transferred to customers at a single point in time, as noted above with the delivery of the Company’s products
to customers, accounted for 100% of our revenue during the year ended December 31, 2017.

Significant Judgments

The Company estimates variable consideration for arrangements where the transaction price is not fully determinable until the
completion of yield testing. The Company estimates variable consideration at the most likely amount to which it expects to be
entitled and includes estimated amounts in revenue to the extent it is probable that a significant reversal of revenue recognized will
not occur when the uncertainty associated with the variable consideration is resolved. Adjustments to revenue is recognized in the
period when the uncertainty is resolved. To date, any adjustments to estimates have not been material.

Practical Expedients and Exemptions

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of
one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services
performed.

Depreciation  expense  was  $2.9  million,  $0.7  million  and  $0.1  million  for  the  years  ended  December  31,  2017,  2016  and  2015,
respectively.  The  Building  is  a  136,750  square  foot  lead  acid  battery  recycling  plant  being  built  in  McCarran,  Nevada.  Equipment
under  construction  at  December  31,  2017  is  primarily  AquaRefining  modules  manufactured  by  the  Company  to  be  used  in  the
McCarran, Nevada recycling plant.

Certain costs necessary to make the recycling facility ready for its intended use have been capitalized, including interest expense on
notes  payable.  Capitalized  interest  totaled  $0.5  million  and  $0.1  million  for  the  years  ended  December  31,  2016  and  2015,
respectively. Capitalization of interest ceased upon completion of the building in early November 2016.

The Company has financed certain of its lab equipment purchases through the use of capital leases. The lease terms are generally
between 24 and 36 months with an option to purchase the asset at the end of the lease for $1. Total lab equipment included in the
above table at December 31, 2017 subject to capital leases is $0.4 million less accumulated depreciation of $0.1 million resulting in
net fixed assets under capital lease of $0.3 million. Total lab equipment included in the above table at December 31, 2016 subject to
capital leases was $0.4 million less accumulated depreciation of $36,000 resulted in net fixed assets under capital lease of $0.4
million. These assets are depreciated using the same useful lives as noted above and included in depreciation expense. See Note 12 –
Notes Payable for minimum future payments related to these equipment leases.

6.         Intellectual Property

On April 13, 2017, the Company entered into an agreement to purchase all the capital shares of Ebonex IPR Limited, a company
registered in England and Wales. Ebonex IPR Limited is a pre-revenue IP-based company that has developed patented technology in
the field of advanced materials and manufacturing methods for advanced lead acid batteries. Total consideration was $2.5 million,
consisting of cash, transaction costs and 123,776 shares of the Company’s common stock, which at the time had a closing market
price of $17.36 per share. In accordance with ASC Topic 805-50, “Business Combinations – Related Issues”, the Company accounted
for the transaction as an asset acquisition and allocated the consideration to the relative fair value of the assets acquired. The
Company determined that the transaction was an asset acquisition rather than a business combination following the guidance in the
above-mentioned standard. In order to be treated as a business combination, the acquired assets and assumed liabilities must
constitute a business. A business requires a set of inputs and processes applied to those inputs that have the ability to contribute to the
creation of outputs. Ebonex IPR Limited has no processes such as strategic management processes, operational processes, or
employees. Further, Ebonex IPR Limited provides no goods or services to customers, nor has it any investment or other revenues.
Therefore, the Company concluded that the acquired assets and assumed liabilities do not constitute a business and are instead treated
as an asset acquisition. Assets acquired consisted of a patent portfolio. The fair value of the patent portfolio, of $112,000, was
determined by management with the assistance of an independent valuation specialist using an income approach. Included in the
purchase were certain fixed assets that have been determined by management to have no immediate value and were not considered in
the valuation of Ebonex IPR.

The Company initially recorded the transaction as an increase of $2.5 million to intellectual property, net on the balance sheet.
Subsequently, due to the fair value of the patent portfolio being significantly less than total consideration, the early development
stage of the technology acquired and the uncertainties inherent in research and development, the Company recorded a non-cash
impairment charge of $2.4 million during the three-month period ended June 30, 2017.

The remaining $0.1 million is being amortized straight-line over a 10-year period.

The  increase  of  $0.5  million  (excluding  the  Ebonex  transaction  detailed  above),  $0.2  million  and  $0.1  million  in  2017,  2016  and
2015, respectively, was due to fees associated with additional patent and trademark filings. The intellectual property balance is being
amortized straight-line over a 10-year period.

ASC Topic 410-20, “Asset Retirement and Environmental Obligations, Asset Retirement Obligations” requires the recording of a
liability in the period in which an asset retirement obligation (ARO) is incurred, in an amount equal to the discounted estimated fair
value of the obligation that is capitalized. In each subsequent fiscal quarter, this liability is accreted up to the final retirement cost.
The determination of the ARO is based on an estimate of the future cost to remove and decontaminate the Company’s facility at
TRIC upon closure. The estimated fair value of the closure costs is based on vendor quotes to remove and decontaminate the
McCarran facility in accordance with the Company’s closure plan as filed with the State of Nevada in its “Application for the
Recycling of Hazardous Waste, by Written Determination” in 2016. The actual costs could be higher or lower than current estimates.
The discounted estimated fair value of the closure costs is $670,000 and the obligation was recorded as of March 31, 2017, when the
obligation was deemed to have occurred. Offsetting this ARO is, as noted in Note 5 above, an asset retirement cost of the same
amount that was capitalized. Accretion of the ARO for the year ended December 31, 2017 was $31,000.

The Company has entered into a facility closure trust agreement for the benefit of the Nevada Division of Environmental Protection
(NDEP), an agency of the Nevada Division of Conservation and Natural Resources. Funds deposited in the trust are to be available,
when and if needed, for potential decontamination and hazardous material cleanup in connection with the closure and/or post-closure
care of the facility. The trustee will reimburse the Company or other persons as specified by the NDEP from the fund for closure and
post-closure expenditures in such amounts as the NDEP shall direct in writing. Through December 31, 2017, $450,000 has been
contributed to the trust fund; $220,000 will be due on October 31, 2018.

10.       Convertible Notes

As described more completely under the caption “Interstate Battery Agreements” below in Note 13, the Company issued to Interstate
Battery System International, Inc. and its wholly-owned subsidiary (collectively “Interstate Battery”) a convertible note with a face
amount of $5.0 million and interest of 11% per annum due May 25, 2019. The note is convertible at $7.12 per share of common
stock. The Company allocated the proceeds from the Interstate Battery agreements to the convertible note, common stock and
warrants comprising the financing agreements based on the relative fair value of the individual securities on the May 24, 2016
closing date of the agreements. Additionally, the convertible notes contained an embedded conversion feature having intrinsic value
at the issuance date, which value the Company treated as an additional discount attributed to the convertible note, subject to
limitations on the absolute amount of discount attributable to the convertible notes and its allocated value. The Company recorded a
corresponding credit to additional paid-in capital attributable to the beneficial conversion feature (“BCF”). The discounts attributable
to the convertible note, an aggregate of $4,975,000, are being amortized using the effective interest method over the three-year term
of the note, maturing on May 24, 2019. Because the discount on the convertible note exceeds 99% of its initial face value, and
because the discount is amortized over the period from issuance to maturity, the calculated effective interest rate is 184.75% per
annum.

Interest cost on the note for the years ended December 31, 2017 and 2016 totaled $ 0.6 million and $0.3 million, respectively.
Amortization of the note discount for the years ended December 31, 2017 and 2016 totaled $0.4 million and $0.1 million,
respectively. Amortization of the deferred financing costs, more fully described in Note 13, totaled $48,000 and $27,000 for the year
ended December 31, 2017 and 2016, respectively.

Private Placement Convertible notes

On October 31, 2014, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with
accredited investors (the “Investors”), pursuant to which the Company issued an aggregate of $6.0 million principal amount of senior
secured convertible notes (the “Private Placement Convertible Notes”). In connection with the sale of the Private Placement
Convertible Notes (the “Bridge Financing”), the Company entered into a registration rights agreement (the “Registration Rights
Agreement”) and a security agreement (the “Security Agreement”) with the Investors. The closing of the Bridge Financing was
completed October 31, 2014.

The principal, $6.0 million, and interest, $0.3 million, of the Private Placement Convertible Notes were converted into 2,511,871
shares of the Company’s common stock at a conversion price of $2.50 per share on August 5, 2015 as part of the Company’s Initial
Public Offering (“IPO”).

Pursuant to the terms of the Private Placement Convertible Notes, the conversion price was subject to adjustments in the event of an
IPO, other financing and upon certain other events. The embedded conversion feature was not clearly and closely related to the host
instrument and was bifurcated from the host Convertible Notes as a derivative, principally because the instrument’s variable exercise
price  terms  would  not  qualify  as  being  indexed  to  the  Company’s  own  common  stock.  Accordingly,  this  conversion  feature
instrument was classified as a derivative liability in the consolidated balance sheet at December 31, 2014. Derivative liabilities were
initially recorded at fair value and were then re-valued at each reporting date, with changes in fair value recognized in earnings during
the reporting period.

The  Company  determined  that  the  initial  fair  value  of  the  embedded  conversion  option  was  $0.2  million.  From  the  aggregate
principal  amount  of  the  Private  Placement  Convertible  Notes  of  $6.0  million,  the  Company  deducted  in  full  the  fair  value  of  the
embedded  conversion  feature  and  offering  costs  of  $0.8  million  as  a  debt  discount.  The  debt  discount  was  amortized  under  the
effective  interest  method  over  the  term  of  the  Convertible  Notes.  Upon  completion  of  the  IPO,  all  remaining  unamortized  debt
discount  and  BCF  were  immediately  expensed.  The  amount  of  issuance  cost  amortized  as  interest  expense  on  the  statements  of
operations was $0.9 million for the year ended December 31, 2015.

The balance of Private Placement Convertible Notes as of December 31, 2014 was as follows (in thousands):

The  Company  calculated  the  fair  value  of  the  embedded  conversion  feature  of  the  Private  Placement  Convertible  Notes  using  the
Monte Carlo simulation, with the observable assumptions as provided in the table below. The significant unobservable inputs used in
the fair value measurement of the reporting entity’s embedded conversion feature were expected stock prices, levels of trading and
liquidity  of  the  Company’s  stock.  Significant  increases  in  the  expected  stock  prices  and  expected  liquidity  would  result  in  a
significantly higher fair value measurement. Significant increases in either the probability or severity of default of the host instrument
would result in a significantly lower fair value measurement (Aggregate fair value in thousands).

The fair value of the embedded conversion feature at the time of the IPO and note conversion into common shares of the Company
was  $6.3  million.  The  increase  of  $5.2  million  in  fair  value  of  the  embedded  conversion  feature  during  2015  until  the  IPO  was
recorded as a change in the fair value of derivative liabilities within the statements of operations.

On  September  8,  2014,  the  Company  entered  into  an  agreement  (the  “Placement  Agent  Agreement”)  with  National  Securities
Corporation (“NSC”) pursuant to which the Company appointed NSC to act as the Company’s placement agent in connection with the
sale of the Company’s securities (“Offering or Offerings”). Specifically, NSC was the placement agent in connection with the sale of
its Private Placement Convertible Notes. The Placement Agent Agreement had an initial term of 180 days after which it will continue
in effect until it’s terminated by either party with 60 days written notice to the other party.

In connection with the sale of the Private Placement Convertible Notes, the Company paid NSC a cash fee of $0.6 million and issued
on  October  31,  2014  to  NSC  warrants  (“Financing  Warrants”)  to  purchase  shares  of  the  Company’s  common  stock.  NSC
subsequently transferred a portion of the Financing Warrants to associated persons. The Financing Warrants were fully vested upon
issuance, have a term of five years, and are immediately exercisable. The Financing Warrants were exercisable into 251,187 shares of
the  Company’s  common  stock  assuming  an  exercise  price  of  $3.00  per  share  (calculated  as  120%  of  the  Private  Placement
Convertible Notes conversion price of $2.50 per share).

The  warrant  holders  have  certain  registration  rights  with  respect  to  the  common  stock  issued  upon  exercise  of  the  Financing
Warrants.

The  Company  calculated  the  fair  value  of  the  Financing  Warrants  using  a  Black  Scholes  Merton  model  with  the  assumptions
provided  in  the  table  below.  The  fair  market  value  of  the  stock  used  prior  to  the  IPO  was  from  409A  valuations  prepared  by  an
outside consultant.

Provided  below  are  the  principal  assumptions  used  in  the  initial  and  subsequent  measurement  of  the  fair  values  of  the  Financing
Warrants (Warrants fair value in thousands):

The  initial  fair  value  of  the  Financing  Warrants  was  accounted  for  as  a  derivative  issuance  cost  and  along  with  the  other  private
placement costs was amortized over the life of the Private Placement Convertible Notes. During the year ended December 31, 2015,
the  Company  recorded  an  increase  of  $0.6  million  in  the  fair  value  of  the  Financing  Warrant  as  a  change  in  the  fair  value  of
derivative liabilities within the statements of operations. On August 5, 2015, after the conclusion of the IPO, the financing warrants
fair value was fixed and the derivative liability of $0.9 million was reclassified to additional paid-in capital.

All of these warrants were exercised via cashless exercises during 2017.

11.       Deferred Rent

On August 7, 2015, the Company signed a lease for 21,697 square feet of mixed office and manufacturing space in Alameda, CA.
The term of the lease is 76 months plus 6 months pre-commencement date for tenant improvement construction. The total cost of the
lease is $3.0 million which is being amortized over 82 months at approximately $37,000 per month. As of December 31, 2016, the
landlord had paid for $0.9 million in tenant improvements. The tenant improvements cost has been included in owned assets and
deferred rent and is being amortized over the life of the lease. Amortization of deferred rent expense for the year ended December
31, 2017 was $177,000. Net deferred rent expense for the years ended December 31, 2016 and 2015 was $29,000 and $163,000,
respectively.

12.       Notes Payable

AMR entered into a $10,000,000 loan with Green Bank on November 3, 2015. The term of the loan is twenty-one years. For the first
twelve months only interest was payable; thereafter monthly payments of interest and principal are due. The interest rate adjusts on
the first day of each calendar quarter equal to the greater of six percent (6%) or two percent (2%) per annum above the minimum
prime lending rate charged by large U.S. money center commercial banks as published in the Wall Street Journal. The terms of the
Loan Agreement  contain  various  affirmative  and  negative  covenants. Among  them, AMR  must  maintain  a  minimum  debt  service
coverage ratio of 1.25 to 1.0 (beginning with the twelve-month period ending March 31, 2017), a maximum debt-to-net worth ratio of
1.0  to  1.0  and  a  minimum  current  ratio  of  1.5  to  1.0. AMR  was  in  compliance  with  all  covenants  as  of  and  for  the  years  ending
December 31, 2016 and 2015. AMR was in compliance with all but the minimum debt service coverage ratio covenant as of and for
each of the three-month periods ended March 31, June 30, September 30 and December 31, 2017. AMR has received a waiver for the
minimum  debt  service  coverage  ratio  covenant  for  each  of  the  three-month  periods  ended  March  31,  June  30,  September  30  and
December 31, 2017.

The  net  proceeds  of  the  loan  was  deposited  into  an  escrow  account  at  Green  Bank.  The  funds  were  released  as  payment  for  the
building constructed in McCarran, Nevada to house AMR’s lead acid recycling operation. Collateral for this loan is AMR’s accounts
receivable, goods, equipment, fixtures, inventory, accessions and a certificate of deposit in the amount of $1,000,000.

The loan is guaranteed by the United States Department of Agriculture Rural Development (“USDA”), in the amount of 90% of the
principal amount of the loan. The Company paid a guarantee fee to the USDA in the amount of $270,000 at the time of closing and
will  be  required  to  pay  to  the  USDA  an  annual  fee  in  the  amount  of  0.50%  of  the  guaranteed  portion  of  the  outstanding  principal
balance of the loan as of December 31 of each year.

The costs associated with obtaining the Green Bank loan of $756,000 were recorded as a reduction to the carrying amount of the note
and are being amortized as interest expense within the condensed consolidated statements of operations over the twenty-one year life
of the loan. Amortization of the deferred financing costs totaled $35,000, $35,000 and $9,000 for the years ended December 31,
2017, 2016 and 2015, respectively.

13.       Stockholders’ Equity

Authorized capital

The authorized capital stock of the Company consists of 50,000,000 shares of common stock, par value $0.001 per share. In the event
of  liquidation  of  the  company,  dissolution  or  winding  up,  the  holders  of  common  stock  are  entitled  to  share  ratably  in  all  assets
remaining after payment of liabilities. The common stock has no preemptive or conversion rights or other subscription rights. There
are no redemption or sinking fund provisions applicable to the common stock. The outstanding shares of common stock are fully paid
and non-assessable.

The holders of the Company’s common stock are entitled to one vote per share. Holders of common stock are entitled to receive a
ratable share of dividends, if any, as may be declared by the board of directors.  

On June 24, 2015, the Company had a reverse stock split whereby each share of issued common stock was converted into 0.91 shares
of  common  stock  of  the  Company. All  share  and  per  share  amounts  in  the  period  preceding  the  stock  split  have  been  adjusted  to
reflect the split retroactively.

On  June  9,  2015,  the  Company  filed  a  registration  statement  on  form  S-1  with  the  Securities  and  Exchange  Commission.  The
registration  was  for  the  sale  of  6,600,000  shares  of  common  stock  to  raise  proceeds  of  $33,000,000  at  an  issue  price  of  $5.00  per
share. On July 31, 2015, the common shares of the Company began trading on the NASDAQ capital markets. On July 31, 2015, the
Company sold 6,600,000 shares of common stock for $33,000,000 less commissions of $2,525,000 and expenses of $577,000 for net
proceeds  of  $29,898,000.  The  form  S-1  included  an  over-allotment  option  of  990,000  common  shares.  On August  13,  2015,  the
Company  sold  641,930  shares  of  the  over-allotment  option  for  $3,210,000  less  commissions  of  $246,000  for  net  proceeds  of
$2,964,000.

On  November  2,  2015,  the  Company  issued  20,000  shares  of  common  stock  to  Insight  Capital  Consultants  Corporation  for  work
performed for the Company.

Interstate Battery Agreements

Investment Agreement

The  Company  entered  into  a  Credit Agreement  dated  May  18,  2016  with  Interstate  Battery  pursuant  to  which  Interstate  Battery
loaned  the  Company  $5,000,000  in  consideration  of  the  Company’s  issuance  of  a  secured  convertible  promissory  note  in  the
original  principal  amount  of  $5,000,000.  The  note  bears  interest  at  the  rate  of  eleven  percent  (11%)  per  annum,  compounding
monthly, and all interest is payable upon the earlier of maturity or conversion of the principal amount. The loan matures on May 24,
2019. The outstanding principal is convertible into shares of the Company’s common stock at a conversion price of $7.12 per share.
The Company’s obligations under the note and Credit Agreement are secured by a second priority lien on the real estate, fixtures and
equipment  at  the  Company’s  recycling  facility  at  McCarran,  Nevada.  The  Credit Agreement  includes  representations,  warranties,
and affirmative and negative covenants that are customary of institutional credit agreements. As of the date of this report, Interstate
Battery has raised a claim that the Company is in technical breach of a negative covenant under loan. The claimed breach relates to
the Company’s failure to obtain Interstate Battery’s prior written consent to the Company’s acquisition of Ebonex IPR, Ltd. In the
event the Company is unable to resolve this matter, Interstate Battery may declare a default under the loan and attempt to accelerate
the payment of all amounts thereunder. There can be no assurance the Company will be able to resolve this matter or that Interstate
Battery  will  not  declare  a  default  under  the  loan  and  attempt  to  accelerate  the  payment  of  all  amounts  thereunder.  The  Company
estimates that resolving the claim will result in a charge of $0.6 million. The Company has recorded the $0.6 million in general and
administrative expenses as of December 31, 2017 with the offset in accrued liabilities.

Pursuant to the Credit Agreement, the Company also issued to Interstate Battery two common stock purchase warrants, including:

● a warrant to purchase 702,247 shares of the Company’s common stock, at an exercise price of $7.12 per share, that is

exercisable upon grant and expires on May 24, 2018; and

● a warrant to purchase 1,605,131 shares of the Company’s common stock, at an exercise price of $9.00 per share, that is

exercisable commencing November 24, 2016 and expires on May 24, 2019.

52

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The warrants contain cashless exercise and standard anti-dilution adjustment provisions. If Interstate converts its convertible note and
exercises both warrants in their entirety, it will own approximately 11.4% of the Company’s common stock at an average price per
share of approximately $7.93.

The  Company  also  entered  into  a  Stock  Purchase Agreement  dated  May  18,  2016  with  Interstate  Battery  pursuant  to  which  the
Company issued and sold to Interstate Battery 702,247 shares of the Company’s common stock at $7.12 per share for gross proceeds
of  approximately  $5,000,000.  The  Stock  Purchase Agreement  includes  customary  representations,  warranties,  and  covenants  by
Interstate Battery and us, and an indemnity from us in favor of Interstate Battery.

In connection with the investment transactions, the Company also entered into an Investors Rights Agreement dated May 18, 2016
with  Interstate  Battery  pursuant  to  which  the  Company  granted  Interstate  Battery  customary  demand  and  piggyback  registration
rights, limited board observation rights over the next three years and limited preemptive rights allowing Interstate Battery the right
to  purchase  its  proportional  share  of  certain  future  equity  issuances  by  the  Company  over  the  next  three  years.  The  Company
included all of the Interstate Battery shares in its S-3 Registration Statement filed with the Securities and Exchange Commission on
August 1, 2016.

The  investment  transactions  with  Interstate  Battery  closed  on  May  24,  2016.  There  were  no  sales  commissions  paid  by  the
Company in connection with its sale of securities to Interstate Battery.

The  Company  allocated  the  $10.0  million  proceeds  from  the  Credit Agreement  and  Stock  Purchase Agreement,  to  the  various
securities based on their relative fair values on the closing date of May 24, 2016.

● The fair value of the note was calculated using an average of the Merrill Lynch US High Yield CCC rate of 16.21% on May 24,

2016 and the Merrill Lynch US High Yield B effective yield of 7.44% on May 24, 2016.

● The fair value of the common stock was based on the closing market price of the Company’s common stock on the NASDAQ

stock market on May 24, 2016.

The fair value of the warrants using the Black-Scholes-Merton Option Pricing Model and the assumptions are listed in the table

The difference between the face value of the convertible note and the allocated amount (which considers both the allocated fair value
of the issued stock and allocated fair value of the warrants) was recorded as an initial discount to the convertible note; common stock
was recorded at its allocated fair value as a credit to par value and additional paid-in capital as appropriate, based on the number of
shares issued, and the allocated fair value of the warrant was credited to additional paid-in capital. After taking into consideration the
amortization of the note discount, the effective interest rate on the convertible note is 184.75%.

The convertible note includes an embedded BCF. The intrinsic value of the BCF was treated as an additional component of the
discount attributable to the convertible note. The initial discount (attributable to the stock and warrants as noted above) and the
discount attributable to the BCF exceeds the face amount of the convertible note. To avoid reducing the initial net carrying value of
the convertible note to or below zero, the discount attributable to the BCF was limited such that the aggregate of all discounts does
not exceed 99.5% of the face amount of the convertible note. The discount is being accreted to interest expense using the effective
interest method over the three-year life of the loan. If the loan is converted prior to its maturity, any remaining discount will be
expensed immediately.

Costs incurred in connection with the deal of $771,000 were allocated between additional paid-in capital and prepaid financing/ debt
discount (“debt issuance costs”) in the same manner as the above allocation of proceeds. The allocated debt issuance costs of
$142,000 were recorded as a reduction to the carrying amount of the convertible note and are being amortized as interest expense
within the condensed consolidated statements of operations over the three-year life of the loan. The remaining $629,000 was
recorded as a reduction to additional paid-in capital.

National Securities Placement

On  May  18,  2016,  the  Company  entered  into  a  Stock  Purchase  Agreement  and  a  Registration  Rights  Agreement  with  certain
accredited investors pursuant to which the Company issued and sold to the investors 719,333 shares of its common stock at a price
of  $7.12  per  share  for  the  gross  proceeds  of  approximately  $5,122,000.  The  Stock  Purchase  Agreement  includes  customary
representations, warranties, and covenants by the investors and the Company, and an indemnity from the Company in favor of the
investors.  The  private  placement  closed  on  May  24,  2016.  The  Company  included  all  of  these  shares  in  its  S-3  Registration
Statement filed with the Securities and Exchange Commission on August 1, 2016.

National Securities Corporation acted as placement agent for the private placement and received sales commission in the amount of
six  percent  (6%)  of  the  gross  proceeds,  or  a  total  of  $307,000  in  commissions  from  us.  In  addition,  we  reimbursed  National
Securities for its out-of-pocket expenses and legal fees in the aggregate amount of $38,000. The total costs of $345,000 have been
recorded as a reduction to additional paid-in capital.

2016 Public Offering

On  November  21,  2016,  the  Company  completed  a  public  offering  of  2.3  million  shares  of  its  common  stock  at  a  public  offering
price of $10.00 per share. Net proceeds to the Company from the public offering were approximately $21.5 million after deducting
underwriting discounts, commissions and offering expenses. In connection with the public offering, the underwriter received a fee of
$1.4  million  and  a  warrant  to  purchase  33,450  shares  of  the  Company’s  common  stock  at  $10.00  per  share  that  is  exercisable
commencing May 20, 2017 and expires on November 21, 2019. The fair value of the warrant, $229,000, was recorded as an increase
to  offering  expenses  and  an  increase  to  additional  paid-in  capital.  The  Company  calculated  the  fair  value  of  the  warrant  using  a
BlackScholes Merton model with the assumptions as follows: $12.66 closing market value on the date of grant; 3-year term; 72%
volatility; 1.36 discount rate and 0% annual dividend rate.

Johnson Controls Agreement

On February 7, 2017, the Company entered into a Stock Purchase Agreement with Johnson Controls pursuant to which the Company
issued and sold to a wholly-owned subsidiary of Johnson Controls International plc, (“Johnson Controls”), 939,005 shares of its
common stock at $11.33 per share for the gross proceeds of approximately $10.6 million. Costs incurred in connection with the
transaction, primarily legal fees, totaled approximately $167,000. The Stock Purchase Agreement includes customary
representations, warranties, and covenants by Johnson Controls and the Company, and an indemnity from the Company in favor of
Johnson Controls.

In connection with the investment transactions, the Company also entered into an Investors Rights Agreement dated February 7, 2017
with Johnson Controls pursuant to which the Company granted Johnson Controls customary demand and piggyback registration
rights, limited board observation rights and limited preemptive rights allowing Johnson Controls the right to purchase its proportional
share of certain future equity issuances by the Company. The board observation and preemptive rights shall expire on the earlier of
(i) such time as Johnson Controls no longer owns 50% of the acquired shares or (ii) the termination of both the Tolling/Lead
Purchase Agreement and Equipment Supply Agreement.  

There were no sales commissions paid by the Company in connection with the sale of its common shares to Johnson Controls.

2017 Public Offering

On December 12, 2017, the Company completed a public offering of 7,150,000 shares of its common stock at a public offering price
of $2.10 per share. Net proceeds to the Company from the public offering were approximately $13.8 million after deducting
underwriting discounts, commissions and offering expenses. In January 2018, the underwriter exercised their overallotment option
resulting in an additional 1,072,500 shares being issued and net proceeds of approximately $2.1 million.

Warrants issued

On September 8, 2014, the Company entered into a consulting agreement with Liquid Patent Consulting, LLC (“LPC”), pursuant to
which LPC agreed to provide management, strategic and intellectual property advisory services. The Consulting Agreement had an
initial term of 180 days after which it will continue in effect until it is terminated by either party with 30 days written notice to the
other party.

As  consideration  for  services  provided  under  the  Consulting Agreement  the  Company  issued  warrants  (“Consulting  Warrants”)  to
LPC for the purchase of an aggregate of 436,364 shares of the Company’s common stock. LPC subsequently transferred a portion of
the Consulting Warrants to a third party. The Consulting Warrants vested upon issue, have a term of three years, an exercise price of
$0.0034375 per share and are immediately exercisable, provided that upon the Company’s consummation of an IPO, the Consulting
Warrants  may  not  be  exercised  until  90  days  after  the  consummation  of  the  IPO.  The  Consulting  Warrants  may  be  exercised  on  a
cashless basis. All of these warrants were exercised during 2017.

In  connection  with  underwriting  the  IPO,  the  Company  issued  on August  5,  2015  to  NSC  warrants  (“IPO  Warrants”)  to  purchase
660,000 shares of the Company’s common stock at an exercise price of $6.00 per share. The IPO Warrants were fully vested upon
issuance,  are  not  exercisable  until  July  30,  2016  and  have  a  term  of  five  years.  The  registration  statement  with  the  Securities  and
Exchange  Commission  included  an  over-allotment  of  shares  available  for  sale  in  addition  to  the  IPO.  On August  13,  2015,  the
Company issued warrants to NSC (“O-A Warrants”) to purchase 64,193 shares of the Company’s common stock at an exercise price
of  $6.00  per  share  for  underwriting  the  over-allotment  sale  of  shares.  The  O-A  Warrants  were  fully  vested  upon  issuance,  are  not
exercisable  until  July  30,  2016  and  have  a  term  of  five  years.  The  fair  values  were  recorded  as  an  increase  to  IPO  costs  and  an
increase to additional paid in capital. All of these warrants were exercised during 2017.

On October 31, 2015, the Company issued warrants to a consultant to purchase 12,500 shares of the Company’s common stock at an
exercise  price  of  $6.00  per  share.  The  warrants  were  fully  vested  on  issuance  and  expire  on  July  30,  2018.  The  fair  value  of  the
warrants, calculated by the Black-Scholes-Merton method, $28,000 was recorded to business development and management costs and
additional paid in capital in 2015. All of these warrants were exercised during 2017.

On November 2, 2015, the Company issued warrants to a consultant to purchase 30,000 shares of the Company’s common stock at an
exercise price of $6.00. The warrants were fully vested upon issuance and have a term of one year. The fair value of the warrants,
calculated  by  the  Black-Scholes-Merton  method,  $36,000  was  recorded  to  business  development  and  management  costs  and
additional paid in capital in 2015. All of these warrants were exercised during 2016.

The  fair  value  of  each  of  the  warrants  was  recorded  as  increase  to  business  development  and  management  costs  and  increase  in
additional paid in-capital.

As  noted  in  the  preceding  section,  warrants  to  purchase  2,305,378  and  33,450  shares  of  the  Company’s  common  stock  were  also
issued for the Interstate Battery deal and the November 2016 Public Offering, respectively, during 2016. Please refer to the above
section for specific valuation assumptions for these warrants.

Warrants exercised

On June 7, 2016, when the five-day average of closing prices for the Company’s common stock was $12.16 per share, 15,203 shares
of the Company’s common stock were issued pursuant to a cashless exercise of a warrant for 30,000 shares of the Company’s
common stock with an exercise price of $6.00 per share.

During the year ended December 31, 2017, 1,175,796 shares were issued pursuant to cash and cashless warrant exercises as detailed
below. Generally, the warrants specify using the preceding five-day average of closing prices for the Company’s common stock in
the calculation of common stock to be issued pursuant to a cashless exercise.

Stock based compensation

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

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

Option modification 
During the three months ended June 30, 2016, the Compensation Committee of the Board of Directors approved the modification of
the terms of a stock option previously granted to a member of its Board of Directors to accelerate vesting and the waiver of the early
termination  of  the  option  based  upon  the  director’s  end  of  service  to  the  Company.  The  modification  resulted  in  additional
compensation expense of $175,000.

Restricted Stock Units

In July 2017, the Company granted 49,751 restricted stock units (RSUs) with a grant date fair value per share of $11.68 to its then

units had vested.

As of December 31, 2017, there is approximately $0.9 million of total unrecognized compensation cost related to the unvested share-

See Note 12 for lease commitments associated with capital leases for fixed assets.

Interstate Battery Agreement commitment

Pursuant to the Interstate Battery Investor Rights Agreement, the Company has agreed to compensate Interstate Battery should either
Stephen Clarke, the Company’s current chief executive officer, or Selwyn Mould, the Company’s current chief operating officer, no
longer  hold  such  positions  or  no  longer  devote  substantially  all  of  their  business  time  and  attention  to  the  Company,  whether  as  a
result of resignation, death, disability or otherwise (such an event referred to as a “key-man event”). The Company has agreed to pay
Interstate Battery $2.0 million, per occurrence, if either officer is subject to a key-man event during the two years following May 18,
2016. The Company also agreed to pay Interstate Battery $2.0 million if either or both officers are subject to a key-man event during
the third year following May18, 2016.

As of the date of this report, Interstate Battery has raised a claim that the Company is in technical breach of a negative covenant under
the Interstate Battery convertible loan. The claimed breach relates to the Company’s failure to obtain Interstate Battery’s prior written
consent to its acquisition of Ebonex IPR, Ltd. The Company is in negotiations with Interstate Battery to resolve the claim and the
Company believes it will be able to resolve that matter. However, in the event the Company is unable to resolve the claim, Interstate
Battery may declare a default under the loan and attempt to accelerate the payment of all amounts thereunder. There can be no
assurance we will be able to resolve this matter or that Interstate Battery will not declare a default under the loan and attempt to
accelerate the payment of all amounts thereunder. The Company estimates that resolving the claim of breach will result in a charge of
$0.6 million. The Company has recorded $0.6 million in general and administrative expense for the year ended December 31, 2017
with the offset in accrued liabilities.

Johnson Controls Agreement Commitment

Pursuant to the Johnson Controls Investor Rights Agreement, the Company has agreed to compensate Johnson Controls should either
Stephen Clarke, the Company’s current chief executive officer, or Selwyn Mould, the Company’s current chief operating officer, no
longer  hold  such  positions  or  no  longer  devote  substantially  all  of  their  business  time  and  attention  to  the  Company,  whether  as  a
result of resignation, death, disability or otherwise (such an event referred to as a “key-man event”). The Company has agreed to pay
Johnson Controls $1.0 million per occurrence, if either officer is subject to a key-man event during the 18 months following February
7, 2017. The Company also agreed to pay Johnson Controls $1.0 million if either or both key-man events occur after 18 months and
prior to 30 months following February 7, 2017.

Legal proceedings

Beginning on December 15, 2017, three purported class action lawsuits were filed in the United Stated District Court for the Northern
District California against the Company, Stephen R. Clarke, Thomas Murphy and Mark Weinswig:  Arlis Hampton vs. Aqua Metals,
Inc.  et  al.,  Case  No  3:17-cv-07142; Grant  Heath  vs.  Aqua  Metals,  Inc.  et  al.,  Case  No  3:17-cv-07196-JST; Lotfy  Arbab  vs.  Aqua
Metals,  Inc.  et  al.,  Case  No  3:17-cv-07270WHA.  Each  of  the  complaints  was  filed  by  persons  claiming  to  be  stockholders  of  the
Company and generally allege violations of the anti-fraud provisions of the federal securities laws based on the alleged issuance of
false and misleading statements of material fact, and the alleged omission to state material facts necessary to make other statements
made not misleading, between May 19, 2016 and November 9, 2017 with respect to the Company’s lead recycling operations. The
complaints seek unspecified damages and plaintiffs’ attorneys’ fees and costs. As of the date of this report, multiple plaintiffs have
filed  motions  seeking  appointment  as  lead  plaintiff.  Briefing  on  those  competing  motions  was  completed  in  early  March,  and  a
hearing is set for May 17, 2018. The Company has not filed a responsive pleading in any of the above actions and does not expect to
do so until a lead plaintiff has been appointed by the Court.

Beginning on February 2, 2018, two purported shareholder derivative actions were filed in the United States District Court for the
District of Delaware against the Company and its current executive officers and directors, Stephen R. Clarke, Selwyn Mould, Mark
Weinswig, Vincent DiVito, Mark Slade and Mark Stevenson, and one former officer and director, Thomas Murphy: Al Lutzker,
Derivatively and on Behalf of Aqua Metals, Inc. v. Stephen R. Clarke, Thomas Murphy, Mark Weinswig, Selwyn Mould, Vincent L.
Divito, Mark Slade and Mark Stevenson and Aqua Metals, Inc., Case No. 1:99-mc-09999; and Chau Nguyen, Derivatively and on
Behalf of Aqua Metals, Inc. v. Stephen R. Clarke, Thomas Murphy, Mark Weinswig, Selwyn Mould, Vincent L. Divito, Mark Slade
and Mark Stevenson and Aqua Metals, Inc., Case No. 1:18-cv-00327. The complaints were filed by persons claiming to be
stockholders of the Company and generally alleges that certain of its officers and directors breached their fiduciary duties to us by
violating the federal securities laws and exposing us to possible financial liability. The complaints seek unspecified damages and
plaintiffs’ attorneys’ fees and costs. As of the date of this report, the Company has not filed a responsive pleading in either action.

The Company’s effective tax rate for the period ended December 31, 2017 was lower than the statutory tax rate primarily because of
the valuation allowance on its US deferred tax assets taxed at lower rates, partially offset by state taxes and tax credits. The income
tax expense for the year ended December 31, 2017, 2016 and 2015 relate to state minimum income tax.

On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act (the “Act”) into law. The new legislation decreases the
U.S. corporate federal income tax rate from 35% to 21% effective January 1, 2018. There was no impact on recorded deferred tax
balances  as  the  remeasurement  of  net  deferred  tax  assets  was  offset  by  a  change  in  valuation  allowance.  The Act  also  includes  a
number  of  other  provisions  including  the  elimination  of  loss  carrybacks  and  limitations  on  the  use  of  future  losses,  repeal  of  the
Alternative  Minimum  Tax  regime,  and  the  introduction  of  a  base  erosion  and  anti-abuse  tax.  These  provisions  are  not  expected  to
have immediate effects on the Company.

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  fully  realized.  Accordingly,  management  has  applied  a  full  valuation  allowance  against  net
deferred tax assets at both December 31, 2017 and December 31, 2016. The net valuation allowance increased by approximately $4.2
million during the year ended December 31, 2017. The increase in net valuation allowance primarily relates to net operating losses
generated during 2017 partially offset by a decrease related to the lower U.S. corporate federal income tax rate effective January 1,
2018.

The  Company  has  Federal  and  California  net  operating  loss  carry-forwards  of  approximately  $24.6  million  and  $2.7  million,
respectively, available to reduce future taxable income which will begin to expire in December 31, 2034 for Federal and California
purposes.

At  December  31,  2017,  the  Company  had  research  and  development  credits  carryforward  of  approximately  $0.3  million  and  $0.5
million  for  Federal  and  California  income  tax  purposes,  respectively.  If  not  utilized,  the  Federal  research  and  development  credits
carryforward will begin to expire in December 31, 2034. The California credits can be carried forward indefinitely.

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.

The Company’s policy is to account for interest and penalties as income tax expense. As of December 31, 2016, the Company had no
interest  related  to  unrecognized  tax  benefits.  No  amounts  of  penalties  related  to  unrecognized  tax  benefits  were  recognized  in  the
provision for income taxes.

The  Company  maintains  liabilities  for  uncertain  tax  positions.  These  liabilities  involve  considerable  judgement  and  estimation  and
are  continuously  monitored  by  management  based  on  the  best  information  available,  including  changes  in  tax  regulations,  the
outcome of relevant court cases, and other information. The Company recognizes potential accrued interest and penalties related to
unrecognized tax benefits as income tax expense. At December 31, 2017, the Company’s total amount of unrecognized tax benefit
was  approximately  $0.2  million,  none  of  which  will  affect  the  effective  tax  rate,  if  recognized.  The  Company  does  not  expect  its
unrecognized benefits to change materially over the next twelve months.

The  Company  files  income  tax  returns  with  the  United  States  federal  government  and  the  State  of  California.  The  Company’s  tax
returns for the prior years remain open to audit for Federal and California purposes.

Prior to January 1, 2017, the Company recognized the excess tax benefits of stock-based compensation expense as additional paid-in
capital (“APIC”), and tax deficiencies of stock-based compensation expense in the income tax provision or as APIC to the extent that
there  were  sufficient  recognized  excess  tax  benefits  previously  recognized.  As  a  result  of  the  prior  requirement  that  excess  tax
benefits  reduce  taxes  payable  prior  to  be  recognized  as  an  increase  in  paid  in  capital,  the  Company  had  not  recognized  certain
deferred tax assets (all tax attributes such as loss or credit carryforwards) that could be attributed to tax deductions related to equity
compensation in excess of compensation recognized for financial reporting.

Effective as of January 1, 2017, the Company adopted a change in accounting policy in accordance with ASU 2016-09 to account for
excess  tax  benefits  and  tax  deficiencies  as  income  tax  expense  or  benefit,  and  to  recognize  previously  unrecognized  deferred  tax
assets  that  arose  directly  from  (or  the  use  of  which  was  postponed  by)  tax  deductions  related  to  equity  compensation  in  excess  of
compensation  recognized  for  financial  reporting.  The  change  was  applied  on  a  modified  retrospective  basis;  no  prior  periods  were
restated as a result of this change in accounting policy.

ASU 2016-09 also eliminates the requirement that excess tax benefits be realized as a reduction in current taxes payable before the
associated  tax  benefit  can  be  recognized  as  an  increase  in  paid  in  capital. Approximately  $0.2  million  of  capitalized  start-up  costs
(none of which were included in the deferred tax assets recognized in the statement of financial position as of December 31, 2016)
have been attributed to tax deduction for stock-based compensation in excess of the related book expense. Under ASU 2016-09, these
previously unrecognized deferred tax assets were recognized on a modified retrospective basis as of January 1, 2017, the start of the
year  in  which  the  Company  adopted ASU  2016-09.  The  capitalized  start-up  costs  recognized  as  of  January  1,  2017,  as  described
above, have been offset by a valuation allowance. As a result, there was no tax-related cumulative-effect to retained earnings for US
tax purpose.

The Company made the election to early adopt ASU 2015-17 at December 31, 2016 to classify all deferred tax assets and liabilities,
along with any related valuation allowance, as noncurrent on the balance sheet.

17.       401(k) Savings Plan

The Company maintains a defined-contribution savings plan under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”).
The 401(k) Plan covers all employees who meet defined minimum age and service requirements and allows participants to defer a
portion of their annual compensation on a pretax basis. The Plan does not currently provide for matching contributions.

19.        Subsequent Events

The Company has evaluated subsequent events through the date which the consolidated financial statements were available to be
issued.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable.

Item 9A.  

Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures.

Our management, with the participation of our chief executive officer and chief financial officer evaluated the effectiveness of our
disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
Based  upon  that  evaluation,  our  management,  including  our  chief  executive  officer  and  chief  financial  officer,  concluded  that  for  the
reasons  described  below  our  disclosure  controls  and  procedures  were  effective  as  of  December  31,  2017  in  ensuring  all  material
information required to be filed has been made known in a timely manner.

(b) Changes in internal control over financial reporting.

There were no changes to our internal control over financial reporting, as defined in Rules 13a-15(f) under the Exchange Act that
occurred during the fiscal quarter ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our
internal control over financial reporting.

(c) Management’s report on internal controls over financial reporting.

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  controls  over  financial  reporting,  as  defined
under  Rule  15a-15(f)  under  the  Exchange Act.  Our  management  has  assessed  the  effectiveness  of  our  internal  controls  over  financial
reporting  as  of  December  31,  2017  based  on  the  framework  established  in  Internal  Control  -  Integrated  Framework  issued  by  the
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“COSO”).  Our  internal  control  system  was  designed  to  provide
reasonable  assurance  to  our  management  and  board  of  directors  regarding  the  preparation  and  fair  presentation  of  published  financial
statements. An  internal  control  material  weakness  is  a  significant  deficiency,  or  aggregation  of  deficiencies,  that  does  not  reduce  to  a
relatively low level the risk that material misstatements in financial statements will be prevented or detected on a timely basis by employees
in  the  normal  course  of  their  work.  Our  management  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of
December 31, 2017, and based on that evaluation, management concluded that our internal control over financial reporting was effective as
of December 31, 2017.

This report does not include an attestation report of our registered public accounting firm regarding internal control over financial
reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to the rules of the Securities
and Exchange Commission that permit us to provide only management’s report in this annual report.

CERTIFICATIONS

(2)Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to
make  the  statements  made,  in  light  of  the  circumstances  under  which  such  statements  were  made,  not  misleading  with  respect to  the
