ITEM 1. BUSINESS.

The Company:

PART I

Sigma  is  a  software  company  that  was  founded  by  scientist-engineers  composed  of  physicists  and  metallurgists  then  working  at  Los  Alamos  National  Labs  for  the
entrepreneurial purpose of developing sophisticated metallurgical products. Since 2016, the Company’s focus has been on solving the complex and challenging problem of how
to best assure the high quality of metal parts manufactured in laser powder bed additive manufacturing, or 3D printing, machines. Sigma and many others believe that until this
problem was solved, 3D manufacturing of metal parts would not be scalable enough to grow past prototyping and mature into a major industry enjoying high quality yields and
cost-efficient production runs. The solution that Sigma developed to solve this problem is In-Process-Quality-Assurance (“IPQA®”) software known as PrintRite3D®.

In 2018, the Sigma team enhanced and added user features to its PrintRite3D® technology. In 2019, the Company began to productize and test PrintRite3D® on various 3D
metal printers at customers’ sites through the Company’s Rapid Test and Evaluation (“RTE”) program. Upon receiving favorable responses from the various RTEs, in 2020 the
Company began to aggressively market PrintRite3D®. However, the worldwide COVID-19 pandemic caused a reduction, and in some cases a freeze, in capital spending within
the Company’s targeted industries and had what the Company believes to be a short-term negative impact on the Company’s expected timing of generating meaningful revenue.
Despite  the  pandemic,  the  Company  moved  forward  with  its  plan  to  market  PrintRite3D®  to  the  following  industry  segments:  (1)  global  manufacturing  companies  with
Additive Manufacturing (“AM”) initiatives; (2) 3D printer Original Equipment Manufacturers (“OEMs”) for purchases of licenses and generating fees and royalties thereafter;
(3)  additive  manufacturing  software  venders  for  alliances  and  licenses  for  co-sales;  and  (4)  research  foundations,  standards  organizations  and  universities,  all  in  service  of
Sigma’s potential for setting the industry standard of measurement by providing data and analytics as a metrics-based quality standard of metal quality for all 3D laser powder
bed manufactured parts, notwithstanding the design, metal, or brand of equipment upon which parts are manufactured.

Additive Metal Manufacturing and the role and need for Sigma’s technology:

The use of 3D printing technology dates back to the 1980s for polymer applications, but the ability to print functional parts from metal alloys has spurred significant interest
and  investment  into  AM  over  recent  years.  AM  is  now  reshaping  the  product  design  process,  entire  supply  chains,  and  the  vast  landscape  of  manufacturing.  Engineers  are
embracing new design freedoms to realize valuable product performance improvements and cost efficiencies with lighter weight, better thermal management capability, better
fluid mixing, customization, and/or the ability to make different structures and textures that yield better part integration.

We believe that there are several significant hurdles to be overcome for broader adoption of additive technologies for the production of industrial metal parts. Among these are
lack of quality, consistency, and industry standards along with cost. The Company believes PrintRite3D® has the potential to contribute to widespread industrialization of 3D
metal  printing.  Additionally,  the  disruption  in  complex  and  rigid  supply  chains  caused  by  COVID-19  exposed  the  country’s  vulnerability  to  shortages  in  times  of  crisis.  In
response, manufacturers are devising strategies to be able to be more agile, increase their ability to manufacture mission critical parts on demand, with more customization, and
closer to where the end part will be needed.

PrintRite3D® Technology and Product Family

PrintRite3D® is an integrated hardware and software edge computing platform, or in-process quality assurance system that combines inspection, feedback, data collection and
critical analysis. It is a 3D printer platform-independent solution that can be installed as a retrofit to an existing 3D printer or requested as a factory option from select 3D
printer OEMs. PrintRite3D® provides a high-fidelity, accurate system that can confidently scale to multi-laser 3D metal printers. The PrintRite3D® system detects potential
anomalies and incorporates machine learning in conjunction with developed metrics to map those metrics to the post-process data. This provides the ability to reduce post-
production testing and costs, while creating a certification framework that serves the needs of end-users, printer manufacturers, and standards organizations.

PrintRite3D was initially developed to work with industrial 3D metal printers using the Powder Bed Fusion (PBF) process, which is the most widely used process for industrial
metal applications. In 2020, we announced PrintRite3D for Direct Energy Deposition, or DED, for metal parts. PrintRite3D DED opens up another segment of the industrial
metal market for Sigma to sell and distribute our technology. In 2021, the Company introduced PrintRite3D Selective Laser Sintering, or (SLS) for polymer materials. The
polymer market is larger and more advanced than the metal market. There is an increasing need for quality and standards within the polymer market to support mission critical
parts such as those being used in aerospace, space exploration, and defense. The Company’s entry into this market was customer driven by a supplier of critical equipment to
the space exploration market. The Company believes that PrintRite3D’s ability to work across a different 3D printers, processes and materials gives it a competitive advantage
and will help accelerate the adoption of 3D printing for industrial applications.

Distribution Methods

Sigma Labs employs a multi-channel distribution model for its IPQA products including a direct sales force, value added resellers (“VARs”) and 3D printer Original Equipment
Manufacturers (“OEMs”). In 2021, the majority of the Company’s revenue was generated by direct sales in North America and Europe. VARs are currently used in Japan and
India.  The  Company  plans  to  extend  its  VAR  channel  outside  of  North  America  and  Europe.  Since  2020,  the  Company  has  moved  aggressively  to  establish  and  extend
relationships with 3D printer OEMs and began to generate revenue from this channel. The revenue generated by the OEMs in 2021 did not meet the Company’s projections due
to several reasons, including but not limited to: (1) the ramp up time for the OEM’s sales force, (2) the ongoing impact of COVID on our European based OEM partners, and
(3) the lack of OEM sales into select vertical markets (e.g., aerospace and space exploration) that require that parts conform to specific quality standards. We expect that the
percentage of the Company’s revenue coming from OEMs will increase in 2022 and beyond.

The Company markets its products through webinars, email and social media campaigns, and participation, both in person and virtually, in industry events and tradeshows. In
addition, the Company collaborates with international standards organizations in the establishment of standards for AM.

Sources and Availability of Parts and Materials

We  have  important  relationships  with  several  suppliers  for  critical  components  of  our  PrintRite3D®  systems,  in  particular  optics  and  data  acquisition  components,  and
development of our user interface. To-date, we have not experienced shortages of components, however, in some cases COVID-19 has resulted in increased lead times and cost
for  certain  parts.  We  manage  the  risk  of  component  shortages  by  sourcing  backup  suppliers,  and  in  the  case  of  our  user  interface,  hiring  engineers  in-house  to  support  the
ongoing development and maintenance.

Dependence on a Few Major Customers and Partners

The Company has established distribution agreements with two international 3D printer OEMs. We expected each to contribute a significant percentage of our 2021 revenue,
however due to the previously discussed reasons, revenue in the first year of the relationship did not meet either company’s expectations. The Company supports the OEMs
with joint marketing programs, field sales and technical support personnel to assist in the sale of its technology. It is the Company’s intent to continue to build the OEM channel
through distribution relationships with other 3D printer OEMs in the future.

Competition

PrintRite3D® is a third-party, agnostic In-Process Quality Assurance system designed to provide a consistent, standards-based measurement and prediction of quality across a
heterogeneous collection of 3D printers. Competition has been primarily from the printer OEMs who offer their own monitoring system, usually as a separately priced option to
its printers. Sigma believes that the future of AM will consist of factories with various generations of printers from various manufacturers. The primary reasons that global
manufacturers will have machines from various vendors is that certain machines and technologies are better suited for different applications than others. Additionally, as the
industry progresses, innovation will accelerate, and new leaders will emerge. Finally, many believe that there will be a consolidation of 3D metal manufacturers and the number
of vendors will decrease from approximately 50 to a much small number over the next decade. Although standards for monitoring are slowly being set by various international
standards organizations, it is highly unlikely that printer OEMs will modify their monitoring systems to work with other OEMs machines. Therefore, we believe that the only
way  to  produce  parts  with  a  consistent  level  of  quality  is  with  a  third-party,  agnostic,  standards  based  IPQA  system,  such  as  PrintRite3D®.  Over  the  past  year  or  so,  new
competitors have entered the market with monitoring technology that follows Sigma’s lead as a 3rd party agnostic system capable of working across 3D printer machine types.
These systems use camera-based technology and machine learning to identify gross defects during the printing process. These solutions are useful; however, they fall short of
determining root cause, and unlike PrintRite3D, are not capable of instructing the printer, through closed-loop control, to vary certain machine variables such as laser power to
avoid creating the defects.

Any contracts that we enter into with governmental agencies will be subject to a variety of federal, state and local laws and regulations. These regulations are aimed at
preventing the inadvertent disclosure of munitions related data or the export of technical knowledge to foreign countries. The work we do with governmental units may also be
subject to laws respecting the confidentiality of any classified or national security information we receive during the course of our activities under any government contract.

Additionally, with respect to our work with government agencies, our sales are driven by pricing based on costs incurred to produce products or perform services under
contracts with the U.S. government. U.S. government contracts generally are subject to Federal Acquisition Regulations (“FAR”), agency-specific regulations that implement or
supplement  FAR,  such  as  the  DoD’s  Defense  Federal  Acquisition  Regulations  and  other  applicable  laws  and  regulations.  These  regulations  impose  a  broad  range  of
requirements, many of which are unique to government contracting, including various procurement, import and export, security, contract pricing and cost, contract termination
and adjustment, and audit requirements. A contractor’s failure to comply with these regulations and requirements could result in reductions of the value of contracts, contract
modifications or termination, and the assessment of penalties and fines and could lead to suspension or debarment from government contracting or subcontracting for a period
of  time.  In  addition,  government  contractors  are  also  subject  to  routine  audits  and  investigations  by  U.S.  government  agencies  such  as  the  Defense  Contract  Audit  Agency
(“DCAA”). These agencies review a contractor’s performance, cost structure, and compliance with applicable laws, regulations, and standards. The DCAA also reviews the
adequacy  of,  and  a  contractor’s  compliance  with,  its  internal  control  systems  and  policies,  including  the  contractor’s  purchasing,  property,  estimating,  compensation,  and
information systems.

As of March 23, 2022, we have several active contracts with government agencies. During fiscal year 2021, we entered into two contracts with government agencies,

and we plan to increase this activity in the future.

Human Capital

As of December 31, 2021, we had 33 full-time employees. We continue to search for additional, qualified personnel, to support our expanding operations in the area of
IPQA® for AM. We believe that our future success depends, in part, upon our continued ability to attract and retain highly skilled employees and management and technical
personnel. Employee engagement is important to us and we focus on continuously enhancing our corporate culture.

Compensation and Benefits

We strive to provide robust and competitive compensation and benefits to our employees. Our benefit programs include bonuses, stock-based compensation awards, a

401(k) plan with employer matching, healthcare and insurance benefits, flexible paid time off and other employee assistance programs.

The  health  and  wellness  of  our  employees  is  also  critical  to  our  success.  In  an  effort  to  keep  our  employees  safe  during  the  COVID-19  pandemic,  we  have
implemented  a  number  of  health-related  measures  including,  but  not  limited  to,  protocols  governing  the  use  of  face-masks  while  on  company  property,  temperature  taking
protocols, a flexible work-from-home policy, cleaning procedures at our offices, and social-distancing protocols, which measures we will continue to monitor.

Corporate Information

We incorporated as Messidor Limited in Nevada on December 23, 1985 and changed our name to Framewaves Inc. in 2001. On September 27, 2010, we changed our

name from Framewaves Inc. to Sigma Labs, Inc.

Our principal executive offices are located at 3900 Paseo del Sol, Santa Fe, New Mexico 87507, and our current telephone number at that address is (505) 438-2576.
Our  website  address  is  www.sigmalabsinc.com.  The  Company’s  annual  reports,  quarterly  reports,  current  reports  on  Form  8-K  and  amendments  to  such  reports  filed  or
furnished pursuant to section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and other information related to the Company, are
available,  free  of  charge,  on  that  website  as  soon  as  we  electronically  file  those  documents  with,  or  otherwise  furnish  them  to,  the  SEC.  The  Company’s  website  and  the

Recent Developments

On February 17, 2022, we announced that Jacob Brunsberg was appointed as President and Chief Operating Officer of the Company. In this position, Mr. Brunsberg
will have responsibility for product direction, strategic relationships, sales, marketing, and engineering. As President and Chief Operating Officer, he will report to Mark K.
Ruport, Sigma’s Chief Executive Officer. Mr. Brunsberg will oversee several strategic initiatives designed to accelerate the growth and performance of the company, including
the  transition  to  a  software  only  offering,  initiating  and  implementing  a  comprehensive  OEM  integration  program,  building  strategic  partnerships,  and  implementing  a  new
subscription-based pricing model as an option to our existing perpetual pricing model. Each of these key initiatives is integral to lowering the additive manufacturing (“AM”)
industry’s technology adoption barriers and easing entry and expansion for manufacturers and OEM partners.

On January 26, 2022, we announced that together with Materialise, a leading provider of additive manufacturing (AM) software and services, we had developed a
breakthrough technology to enhance the scalability of metal AM applications. The new platform combines the Materialise Control Platform and Sigma Labs’ PrintRite3D®
sensor technology to allow users to identify and correct metal build issues in real-time. With added control over their unique processes, manufacturers can optimize metal AM
processes for consistency and repeatability, key factors in scaling AM operations for serial production.

On  January  25,  2022,  we  announced  that  our  PrintRite3D®  in-process  quality  assurance  solution  had  been  purchased  by  Auburn  University,  based  in  Auburn,
Alabama. The PrintRite3D solution will be installed on the university’s EOS M290 machine and is the start of an academic and industrial collaboration between the university
and Sigma Labs, and we will deploy the system under a commercial lease/purchase program that provides more flexible and acceptable terms for academic institutions and
early adopters.

PrintRite3D will be implemented to support several projects at the Auburn University National Center for Additive Manufacturing Excellence (NCAME) to utilize 3D
printed  (additively  manufactured)  components  to  improve  commercial  air  and  space  travel.  As  reported  by  the  Auburn  University  Samuel  Ginn  College  of  Engineering,
NCAME is funded by a $3 million grant from the Federal Aviation Administration (FAA). The objective is to address issues related to the variability in additive manufacturing
machines, as well as generate an understanding of how microscopic anomalies in the 3D-printed metals affect overall fatigue and fracture properties.

On January 20, 2022, we announced that our PrintRite3D® in-process quality assurance solution will be certified to work with Aconity3D’s line of 3D metal printers
and  available  as  a  standard  option  via  Aconity3D’s  online  configurator.  Aconity3D  will  designate  their  printers  as  ‘PrintRite3D  Ready™’.  As  an  original  equipment
manufacturer (OEM) Aconity3D will sell, install and support PrintRite3D as an integrated solution to its customers.

Aconity3D is a machine manufacturer for laser-based 3D printing of metals, with a focus on the buildup of customer specific systems for Laser Powder Bed Fusion
(LPBF),  in  which  metal  particles  are  fused  layer  upon  layer  by  a  laser.  The  Aconity  System  Framework  allows  full  customization  of  each  machine  for  customers’  specific
applications. Aconity3D’s customers and partners include leading industrial, aviation and automotive companies, and world-renowned institutes and universities at the forefront

ITEM 1A. RISK FACTORS.

Our business is subject to numerous risks. We caution you that the following important factors, among others, could cause our actual results to differ materially from
those expressed in statements made by us or on our behalf in filings with the SEC, press releases or communications with investors and others. Any or all of our statements in
this annual report and in any other public statements we make may turn out to be wrong. They can be affected by inaccurate assumptions or by known or unknown risks and
uncertainties. The factors mentioned in the discussion below will be important in determining future results. Consequently, actual future results may vary materially from those
anticipated in this annual report or our other public statements. The occurrence of any of the events or developments described below could harm our financial condition, results
of operations, business and prospects. In such an event, the market price of our common stock could decline. Additional risks and uncertainties not presently known to us or
that we currently deem immaterial also may have similar adverse effects on us.

Risks Related to Our Business

We are not currently profitable and may never become profitable.

We  have  incurred  losses  in  every  reporting  period  since  we  commenced  business  operations  in  2010  and  expect  to  continue  to  incur  significant  losses  for  the
foreseeable future. Our net loss applicable to common stockholders for the years ended December 31, 2021 and 2020 were $7,488,172 and $7,009,414, respectively. As of
December 31, 2021, our accumulated deficit was $40,593,180. There is no assurance that any revenues we generate will be sufficient for us to become profitable or to maintain
profitability. Our revenues for the years ended December 31, 2021 and December 31, 2020 were $1,651,765 and $807,488, respectively, and our operating expenses for those
periods  were  $9,571,185  and  $5,914,299,  respectively.  Our  current  revenues  are  not  sufficient  to  fund  our  operations.  We  cannot  predict  when,  if  ever,  we  might  achieve
profitability and we are not certain that we will be able to sustain profitability, if achieved. If we fail to achieve or maintain profitability, the market price of our securities is
likely to be adversely affected.

We will require additional financing to continue our operations, and there is no assurance that we will be able to obtain such financing on acceptable terms, or at all.

As of December 31, 2021, we had cash of $11,447,047. We will need to raise additional financings to fund our operations, maintain compliance with the NASDAQ
listing  requirements  and  implement  our  business  plan.  There  is  no  assurance  as  to  the  amount  and  availability  of  any  required  future  financing  or  the  terms  thereof.  Such
financing, if in the form of equity, may be highly dilutive to our existing stockholders and may otherwise include onerous terms. If in the form of debt, such financing may
include covenants and repayment obligations which may be difficult to meet and that could adversely affect our business operations. To the extent that funds are not available to
us, we may be required to delay, limit or terminate our business operations and may lose our NASDAQ listing.

Our operating history makes evaluation of our business difficult.

We are continuing to develop our technologies and to implement our business plan. Our ability to implement a successful business plan remains unproven, and there is
no assurance that we will ever generate sufficient revenues to sustain our business. Our operating history, together with the other risks discussed in this “Risk Factors” section,
may make it difficult for you to evaluate our business in connection with making a decision about whether to invest in our securities.

9

 
 
 
 
 
 
 
 
 
 
 
 
 
We face the risks normally associated with a new business.

We face all of the risks inherent in a new business, including the expenses, difficulties, complications and delays frequently encountered in connection with conducting
new operations and efforts to develop and commercialize technologies. These uncertainties include developing our technologies and our brand name, raising capital to meet our
working capital requirements and developing a customer base, among others. If we are not effective in addressing these risks, we will not be able to operate profitably in the
future, and we may not have adequate working capital to meet our obligations as they become due.

Our business may be adversely affected by a global economic downturn.

Any economic downturn generally could cause a drop in government spending and business investment, which could have a material adverse effect on our business.
Further, as a result of the current global economic and geopolitical situation, there may be a disruption or delay in performance by our third-party contractors and suppliers. If
such third parties are unable to adequately satisfy their contractual commitments to us in a timely manner, our business could be adversely affected.

We could incur significant damages if we are unable to adequately discharge our contractual obligations.

Our failure to comply with contract requirements or to meet our clients’ performance expectations on a contract could materially and adversely affect our financial
performance and our reputation. This, in turn, would impact our ability to compete for new clients and contracts. Our failure to meet contractual obligations could also result in
substantial  actual  and  consequential  damages  under  the  terms  of  such  contracts.  In  addition,  some  of  our  contracts  require  us  to  indemnify  clients  for  our  failure  to  meet
performance standards and/or contain liquidated damages provisions and financial penalties related to performance failures. Although we do have liability insurance, the policy
limits may not be adequate to provide protection against all such potential liabilities.

Some of our clients may terminate our contracts prior to completion, which could result in revenue shortfalls and reduce profitability or cause losses on contracts.

Some of our contracts with clients contain initial or base periods of one or more years, as well as option periods typically covering more than one-half of the contract’s
initial duration. However, such clients are under no obligation to exercise the option to extend the contract term. The profitability of some of our contracts could be adversely
impacted if such options are not exercised and the contract term is not extended accordingly. Additionally, our contracts contain provisions permitting a client to terminate the
contract on short notice, with or without cause. The unexpected termination of significant contracts could result in significant revenue shortfalls. If revenue shortfalls occur and
are not offset by corresponding reductions in expenses, our business could be adversely affected. We cannot anticipate if, when or to what extent a client might terminate its
contracts with us.

10

 
 
 
 
 
 
 
 
 
 
 
 
We may not be able to effectively control and manage our growth, which would negatively impact our operations.

We have operated our current line of business for approximately eleven years, and we expect to grow in the near future as our business develops and becomes further
established. If our business grows as we anticipate, it will be necessary for us to manage our expansion in an orderly fashion. Any significant growth in our activities or in the
market  for  our  services  will  require  extension  of  our  managerial,  operational,  marketing  and  other  resources.  Future  growth  will  also  impose  significant  additional
responsibilities upon the members of management to identify, recruit, maintain, integrate, and motivate new employees. Our failure to manage growth effectively may lead to
operational  inefficiencies  that  will  have  a  negative  effect  on  our  profitability.  Additionally,  if  our  growth  comes  at  the  expense  of  providing  quality  service  and  generating
reasonable profits, our ability to successfully bid for contracts and our profitability will be adversely affected. We cannot assure investors that we will be able to effectively
manage any future growth we may experience.

Failure to obtain adequate insurance coverage could put us at risk for uninsured losses.

Some or all of our customers may require insurance as a requirement to conduct business with us. Although we currently have product liability insurance, we may be
unable to obtain or maintain adequate liability insurance on acceptable terms, if at all, and there is a risk that our insurance will not provide adequate coverage against our
potential losses. Additionally, there are certain types of losses that may not be insurable at a cost that we can afford, and insurance may not be available at any cost with respect
to certain losses. Claims or losses in excess of any insurance coverage we may obtain, or the lack of insurance coverage, could put us at risk of loss for any uninsured loss,
which would have a material adverse effect on our business and financial condition.

We are dependent on key personnel, and the loss of any of these individuals could harm our business.

We depend on key scientific and other personnel. The loss of any of these individuals could harm our business and significantly delay or prevent the achievement of
our business objectives. In addition, our delivery of services will be labor-intensive: when we are awarded a contract, we may need to quickly hire project leaders and project
management  personnel. The  additional  staff  may  also  create  a  concurrent  demand  for  increased  administrative  personnel.  The  success  of  our  business  will  require  that  we
attract, develop, motivate and retain:

● experienced and innovative executive officers;

● senior managers who have successfully managed or designed programs in the public sector; and

● information technology professionals who have designed or implemented complex information technology projects.

Innovative, experienced and technically proficient individuals are in great demand and are likely to remain a limited resource. We may be unable to continue to attract
and  retain  desirable  executive  officers,  senior  managers,  and  technology  professionals.  Our  inability  to  hire  sufficient  personnel  on  a  timely  basis  or  the  loss  of  significant
numbers of executive officers and senior managers could adversely affect our business.

We may be dependent on cash flow and payments from customers in order to meet our expense obligations.

A number of factors may cause our revenues, cash flow and operating results to vary from quarter to quarter, including the following:

● the progression of contracts;

● the rate of customer adoption of our new subscription pricing program;

11

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● the commencement, completion or termination of contracts during any particular quarter;

● the schedules of government agencies and large multinational corporations for awarding contracts;

● the failure of our customers to fulfill their obligations under contracts with us; and

● the term of awarded contracts and potential acquisitions.

Changes in the volume of activity and the number of contracts commenced, completed or terminated during any quarter may cause significant variations in our cash
flow from operations because a significant portion of our expenses are fixed. Fixed expenses include, rent, payroll, insurance, employee benefits, taxes and other administrative
costs  and  overhead.  Moreover,  we  expect  to  incur  significant  operating  expenses  during  the  start-up  and  early  stages  of  large  contracts  and  typically  do  not  receive
corresponding payments in that same quarter.

We may make acquisitions in the future that we are unable to effectively manage given our limited resources.

We may choose to grow our business by acquiring other entities. We may be unable to manage businesses that we have acquired or to integrate them successfully
without incurring substantial expenses, delays or other problems that could negatively impact our results of operations. Moreover, business combinations involve additional
risks, including:

● diversion of management’s attention;

● loss of key personnel;

● our becoming significantly leveraged as a result of the incurrence of debt to finance an acquisition;

● assumption of unanticipated legal or financial liabilities;

● unanticipated operating, accounting or management difficulties in connection with the acquired entities;

● amortization of acquired intangible assets, including goodwill; and

● dilution to existing stockholders and our earnings per share.

Also,  client  dissatisfaction  or  performance  problems  with  an  acquired  firm  could  materially  and  adversely  affect  our  reputation  as  a  whole.  Further,  the  acquired

businesses may not achieve the revenues and earnings that we anticipated.

We may be unable to develop or commercialize new and rapidly evolving technologies.

Many  of  our  activities  involve  developing  products  or  processes  that  are  based  upon  new,  rapidly  evolving  technologies.  The  ability  to  commercialize  or  further

develop these technologies could fail for a variety of reasons, both within and outside of our control.

We may be unable to protect our intellectual property rights.

Our success in part depends on the ability to protect our intellectual property and proprietary technology. To do so, we will be required to prosecute patent applications
and  maintain  patents,  obtain  new  patents  and  pursue  trade  secret  and  other  intellectual  property  protection.  There  can  be  no  assurance  that  our  program  for  protection  of
intellectual property and proprietary technology will be sufficient to protect our intellectual property and proprietary technology from competitors. Our business is also subject
to the risk that our issued patents will not provide us with significant competitive advantages if, for example, a competitor was to independently develop or obtain similar or
superior  technologies.  In  addition,  our  issued  patents  may  be  challenged  or  infringed  upon  by  third  parties.  The  enforcement  of  intellectual  property  rights  is  subject  to
considerable uncertainty and can be expensive and time-consuming. Patent reform laws and court decisions interpreting such laws, may create additional uncertainty around our
ability  to  obtain  and  enforce  patent  protection.  Any  significant  impairment  of  our  intellectual  property  rights  could  harm  our  business  and  our  ability  to  compete.  The
unauthorized use of our intellectual property could make it more expensive to do business and harm our operating results. Proprietary trade secrets and unpatented know-how
are  also  very  important  to  our  business;  however,  trade  secrets  are  difficult  to  protect.  Our  employees,  consultants,  contractors,  outside  scientific  collaborators  and  other
advisors may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may not provide an adequate remedy in the event
of unauthorized disclosure of confidential or proprietary information.

We may be sued by third parties who claim that we have infringed their intellectual property rights.

We  may  be  exposed  to  future  litigation  by  third  parties  based  on  claims  that  our  research,  development  and  commercialization  activities  infringe  the  intellectual
property rights of third parties to which we do not hold licenses or other rights, or that we have misappropriated the trade secrets of others. Any litigation or claims against us,
whether or not valid, could result in substantial costs, and could place a significant strain on our financial and human resources. In addition, if successful, such claims could
cause us to pay substantial damages. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that
some of our confidential information could be compromised by disclosure during this type of litigation.

Our bylaws contain provisions indemnifying our officers and directors against all costs, charges, and expenses incurred by them.

Our bylaws contain provisions with respect to the indemnification of our officers and directors against all costs, charges and expenses actually and reasonably incurred
by an officer or director paid to settle an action or satisfy a judgment in a civil, criminal or administrative action or proceeding to which he or she is made a party by reason of
being or having been one of our directors or officers. To the extent that our directors’ and officers’ insurance policy does not provide reimbursement for such costs, charges,
expenses and other amounts, we may incur substantial expenses in satisfying our indemnification obligations.

Our operating costs could be significantly higher than we expect, and this could reduce our future profitability.

In addition to general economic conditions, market fluctuations and international risks, significant increases in operating, development and implementation costs could

adversely affect us due to numerous factors, many of which are beyond our control.

13

 
 
 
 
 
 
 
 
 
 
 
 
A cyber incident could result in information theft, data corruption, operational disruption and/or financial loss.

Businesses  have  become  increasingly  dependent  on  digital  technologies  to  conduct  day-to-day  operations.  At  the  same  time,  cyber  incidents,  including  deliberate
attacks or unintentional events, have increased. A cyber-attack could include gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive
information, corrupting data, or causing operational disruption or result in denial of service on websites. We depend on digital technology, including information systems and
related infrastructure, to process and record financial and operating data, and communicate with our employees and business partners. Our technologies, systems, networks, and
those  of  our  business  partners  may  become  the  target  of  cyber-attacks  or  information  security  breaches  that  could  result  in  the  unauthorized  release,  gathering,  monitoring,
misuse, loss or destruction of proprietary and other information, or other disruption of our business operations. Although to-date we have not experienced any losses relating to
cyber-attacks, there is no assurance that we will not suffer such losses in the future. As cyber threats continue to evolve, we may be required to expend significant additional
resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities.

Our results of operations may be negatively impacted by the COVID-19 pandemic.

The  spread  of  the  coronavirus,  which  has  caused  a  broad  impact  globally,  including  restrictions  on  travel  and  quarantine  policies  put  in  place  by  businesses  and
governments, may have a material economic effect on our business. Additionally, the coronavirus may result in disruption of financial markets, which may reduce our ability to
access capital either at all or on favorable terms.

Risks Related to Our Securities

The price of our securities is subject to volatility related or unrelated to our operations, which could result in substantial losses for our stockholders.

Between January 1, 2021 and December 31, 2021, the trading price of our common stock has ranged from a low of $1.77 to a high of $7.64 and could be subject to
wide fluctuations in the future in response to various factors, some of which are beyond our control. These factors include those discussed previously in this “Risk Factors”
section and others, such as:

● delays or failures in the commercialization of our current or future products and services;

● quarterly variations in our results of operations or those of our competitors;

● changes in our earnings estimates or recommendations by securities analysts or adverse publicity about us or our products or services;

● announcements by us or our competitors of new products and services, significant contracts, commercial relationships, acquisitions or capital commitments;

● adverse developments with respect to our intellectual property rights;

● commencement of litigation involving us or our competitors;

● any major changes in our board of directors or management;

● market conditions in our industry; and

● general economic conditions in the United States and abroad.

In addition, the stock market, in general, may experience broad market fluctuations, which may adversely affect the market price or liquidity of our securities.

We could be subject to securities class action litigation.

Any sudden decline in the market price of our securities could trigger securities class action lawsuits against us. If any of our stockholders were to bring such a lawsuit
against us, we could incur substantial costs defending the lawsuit and the time and attention of our management would be diverted from our business and operations. We also
could be subject to damages claims if we are found to be at fault in connection with a decline in our market price of our securities.

Historically, there has been a limited trading market in our common stock, and you may therefore have difficulty selling your securities at a price that you determine
is satisfactory.

Our common stock is listed on The Nasdaq Capital Market. Historically, there has been a limited trading market for our common stock. There is no assurance that our
common stock will actively trade in the public market at or above a price that you consider acceptable. If an active market for our common stock is not maintained, it may be
difficult for you to sell your shares of common stock when you wish to sell them or at a price that you consider satisfactory. An inactive trading market may also impair our
ability  to  raise  capital  to  continue  to  fund  operations  by  selling  securities  and  may  impair  our  ability  to  acquire  other  companies  or  technologies  by  using  our  securities  as
consideration.

There is no assurance that we will satisfy the continued listing requirements of The NASDAQ Capital Market.

We cannot assure you that we will be able to continue to satisfy the continued listing requirements of The Nasdaq Capital Market. For example, there is no assurance
that our common stock will continue to have a bid price of at least $1.00 per share, which is the minimum bid price under such continued listing requirements, or that we will
be able to satisfy other quantitative continued listing requirements, including the minimum stockholders’ equity requirement of at least $2,500,000 for continued listing on The
Nasdaq  Capital  Market,  which  we  have  previously  failed  to  satisfy.  If  we  fail  to  satisfy  a  Nasdaq  requirement  for  continued  listing,  Nasdaq  could  provide  notice  that  our
common stock will become subject to delisting. In such event, Nasdaq rules would permit us to appeal the decision to reject our proposed compliance plan or any delisting
determination to a Nasdaq Hearings Panel. If our securities are de-listed from The Nasdaq Capital Market, our stockholders could incur material adverse consequences such as
reduced  liquidity  for  their  securities  and  reduced  market  prices  for  their  securities.  Following  such  de-listing,  we  could  encounter  increased  difficulty  in  issuing  additional
securities at an attractive price, or at all, in order to fund our operations.

You may experience additional dilution as a result of future equity offerings.

In  order  to  raise  additional  capital,  we  may  in  the  future  offer  additional  shares  of  our  common  stock  or  other  securities  convertible  into  or  exchangeable  for  our
common stock. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions
may be lower than the price per share that you paid for our common stock.

We have broad discretion in the use of the net proceeds of our securities offerings and may not use them effectively.

We intend to use our cash for the development of our products and services. Our management has broad discretion in the use of cash and will have the right to use our
cash in ways that differ substantially from our current plans. Management may spend our cash in ways that do not improve our results of operations or enhance the value of our
securities. The failure by management to apply funds effectively could result in financial losses that could have a material and adverse effect on our business and cause the
market price of our securities to decline.

We do not intend to pay dividends on our common stock, and your ability to achieve a return on your investment will depend on appreciation in the market price of
our securities.

We currently intend to invest our future earnings, if any, to fund our growth and not to pay any cash dividends on our common stock. Since we do not intend to pay
dividends,  your  ability  to  receive  a  return  on  your  investment  will  depend  on  any  future  appreciation  in  the  market  price  of  our  securities.  There  is  no  assurance  that  our
securities will appreciate in price.

15

 
 
 
 
 
 
 
 
 
 
 
 
 
 
If securities or industry analysts do not publish research or reports about us, or if they issue adverse or misleading opinions regarding us or our securities, the market
price of our securities and their trading volume could decline.

If we do not obtain and maintain research coverage by securities and industry analysts, the market price for our securities may be adversely affected. The market price
of  our  securities  also  may  decline  if  any  analyst  who  covers  us  issues  an  adverse  or  erroneous  opinion  regarding  us,  our  business  model,  our  intellectual  property  or  our
performance. If one or more analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause the
market price of our securities and their trading volume to decline and possibly adversely affect our ability to engage in future financings.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders
of a large number of shares intend to sell shares, could reduce the market price of our common stock. As of December 31, 2021, we had 10,498,802 outstanding shares of
common stock. Future sales of a large number of our shares or upon exercise of our outstanding warrants and stock options, or the perception that a large number of shares may
be sold, could have a material adverse effect on the trading price of our common stock.

We will incur significant costs to ensure compliance with U.S. and Nasdaq reporting and corporate governance requirements.

We  incur  significant  costs  associated  with  our  public  company  reporting  requirements  and  with  applicable  U.S.  and  Nasdaq  corporate  governance  requirements,
including requirements under the Sarbanes-Oxley Act of 2002 and other rules implemented by the SEC and Nasdaq. These applicable rules and regulations also make it more
difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced policy limits and coverage or incur substantially
higher costs to obtain the same or similar coverage. As a result, it may be difficult for us to attract and retain qualified individuals to serve on our board of directors or as
executive officers.

If we fail to maintain effective internal control over financial reporting, the market price of our securities may be adversely affected.

As a public reporting company, we are required to establish and maintain effective internal control over financial reporting. Failure to establish such internal control, or
any failure of such internal control once established, could adversely impact our public disclosures regarding our business, financial condition or results of operations. Any
failure  of  our  internal  control  over  financial  reporting  could  also  prevent  us  from  maintaining  accurate  accounting  records  and  discovering  accounting  errors  and  financial
frauds.

Rules adopted by the SEC pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 require annual assessment of our internal control over financial reporting. The
standards that must be met for management to assess the internal control over financial reporting as effective are complex, and require significant documentation, testing and
possible remediation to meet the detailed standards. We may encounter problems or delays in completing activities necessary to make an assessment of our internal control over
financial reporting. If we cannot assess our internal control over financial reporting as effective, investor confidence and share value may be negatively impacted. In addition,
management’s assessment of internal control over financial reporting may identify weaknesses and conditions that need to be addressed in our internal control over financial
reporting  or  other  matters  that  may  raise  concerns  for  investors.  Any  actual  or  perceived  weaknesses  and  conditions  that  need  to  be  addressed  in  our  internal  control  over
financial reporting (including those weaknesses identified in our periodic reports), or disclosure of management’s assessment of our internal control over financial reporting
may have an adverse impact on the price of our securities.

Provisions  in  our  articles  of  incorporation  and  bylaws  could  discourage  a  takeover  that  stockholders  may  consider  favorable  and  may  lead  to  entrenchment  of
management.

Our articles of incorporation and bylaws contain provisions that could delay or prevent changes in control or changes in our management without the consent of our

board of directors. These provisions include the following:

● a classified board of directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of a majority of our board of

directors;

● no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;

● the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of

a director, which prevents stockholders from being able to fill vacancies on our board of directors;

● the ability of our board of directors to authorize the issuance of additional shares of preferred stock and to determine the terms of those shares, including preferences
and voting rights, without stockholder approval, which could adversely affect the rights of our common stockholders or be used to deter a possible acquisition of our
company;

● the ability of our board of directors to alter our bylaws without obtaining stockholder approval;

● the required approval of the holders of at least two-thirds of the shares entitled to vote at an election of directors to adopt, amend or repeal our bylaws or repeal the

provisions of our articles of incorporation and bylaws regarding the election and removal of directors;

● a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

● the requirement that a special meeting of stockholders may be called only by the chairman of the board of directors, the chief executive officer, the president (in the
absence of a chief executive officer) or the board of directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action,
including the removal of directors; and

● advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted upon at a
stockholders’ meeting, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or
otherwise attempting to obtain control of us.

● the ability of our directors to issue one or more series of preferred stock with dividend, liquidation, conversion, voting or other rights which would dilute the interest of

or impair the voting power of our common stockholders.

These provisions could inhibit or prevent possible transactions that some stockholders may consider attractive.

We could issue one or more additional series of shares of preferred stock with the effect of diluting existing stockholders and impairing their voting and other rights.

Our  Board  of  Directors  is  authorized  to  issue  up  to  10,000,000  shares  of  preferred  stock  and  may  determine  the  terms  of  future  preferred  stock  offerings  without
further action by our stockholders. If we issue preferred stock, it could affect your rights or reduce the value of our outstanding common stock. In particular, specific rights

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Overview

Sigma  is  a  leading  provider  of  in-process  quality  assurance  (IPQA®)  software  to  the  additive  manufacturing  industry.  Sigma  specializes  in  the  development  and
commercialization of real-time monitoring solutions known as PrintRite3D® for 3D metal advanced manufacturing technologies. PrintRite3D detects and classifies defects and
anomalies  real-time  during  the  manufacturing  process,  enabling  significant  cost-savings  and  production  efficiencies.  We  are  dedicated  to  setting  the  quality  standard  for
Additive  Manufacturing  and  accelerating  the  worldwide  adoption  of  3D  metal  printing.  We  work  closely  with  international  standards  organizations,  renowned  universities,
research organizations, advanced manufacturers, and leading design and simulation software companies. PrintRite3D is printer agnostic and works with most of the leading 3D
metal printers.

Long-Term Strategic Direction

In January 2022, we announced the foundational elements of a three-year plan that we believe will increase the Company’s ability to achieve its mission of setting the
quality standard for additive manufacturing. The combined strategies are geared at making our technology more consumable in terms of ease of use and cost by end users, both
for initial purchases and expansion opportunities, making it easier for original equipment manufacturers (“OEMs”) to embed our technology and generate attractive revenue
streams for the OEM, and finally increasing the Company’s gross margins by moving towards a software-only solution.

To lower the barrier for initial users and for expansion opportunities within end users with a large number of printers, the Company announced that it will be offering
its current PrintRite3D integrated hardware and software solution on a subscription basis. The impact of the change will reduce the initial upfront cost to a new user from over
$100,000 to approximately $3,000-$4,000 per month. In addition, the subscription model will smooth out the Company’s revenue and cash receipts while making them more
predictable.

In order to expand the number of OEMs distributing our technology, we recently launched a three-tiered OEM program directed to: (1) new OEMs without their own
quality assurance or monitoring solution; (2) established OEMs with a quality monitoring offering, but who have customers with multiple printers from multiple OEMs and
want a single 3rd party quality and analytics solution with consistent quality metrics across printers, processes and materials; and (3) OEMs building open APIs to integrate
components of Sigma’s proprietary technology with their current offerings.

In 2019, Sigma entered the market with a productized integrated hardware/software solution to address the retrofit market, i.e., end users that had purchased a printer,
and wanted a 3rd party quality and analytics solution. Subsequently, the Company was successful in creating initial partnerships with OEMs such as Additive Industries and
DMG  Mori  to  offer  PrintRite3D  as  an  integrated  hardware/software  edge  computing  solution.  We  are  now  working  with  OEMs  on  their  next  generation  printers  to  offer  a
software-only  solution  that  will  utilize  the  printer’s  computing  infrastructure  and  dramatically  reduce  the  overall  cost  of  its  technology,  enabling  the  opportunity  to  move
towards a software only embedded solution on every printer sold by partner OEMs.

The combination of subscription pricing and the software-only embedded OEM offerings are intended to make our technology more affordable to acquire and easier

for OEM’s to bundle, distribute and support in an effort to become the industry standard.

Covid-19 Business Update

The worldwide COVID-19 pandemic caused a reduction, and in some cases a freeze, in capital spending within the Company’s targeted industries and had what the
Company  believes  to  be  a  short-term  negative  impact  on  the  Company’s  expected  timing  of  generating  meaningful  revenue.  Further,  the  future  impact  of  the  outbreak,
including variations of the virus, is highly uncertain so that no assurance can be given that the outbreak will not have a material adverse impact on the future results of the
Company. It is also uncertain as to any further disruption of the financial markets, which may reduce our ability to access capital, either at all, or on favorable terms.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and
assumptions that affect the reported assets, liabilities, sales and expenses in the accompanying financial statements. Critical accounting policies are those that require the most
subjective and complex judgments, often employing the use of estimates about the effect of matters that are inherently uncertain. By their nature, changes in these assumptions
and estimates could significantly affect our financial position or results of operations. Significant accounting estimates that may materially change in the near future are revenue
recognition, impairment of long-lived assets, values of stock compensation awards and stock equivalents granted as offering costs, and allowance for bad debts and inventory

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
obsolescence. Such critical accounting policies, including the assumptions and judgments underlying them, are disclosed in Note 1 to the Financial Statements included in this
Annual  Report.  However,  we  do  not  believe  that  there  are  any  alternative  methods  of  accounting  for  our  operations  that  would  have  a  material  effect  on  our  financial
statements.

19

 
 
 
The critical accounting policies and estimates addressed below reflect our most significant judgements and estimates used in the preparation of our financial statements

Revenue Recognition - The Company’s revenue is derived primarily from sales of our software and related hardware suite and from providing engineering services
under  contracts.  Generally,  revenue  is  recognized  upon  the  transfer  of  promised  goods  or  services  to  customers  in  an  amount  that  reflects  the  consideration  to  which  the
Company expects to be entitled in exchange for those goods or services. Significant estimates and judgements for determining revenue recognition include: (1) identifying the
contract, or contracts, with our customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to
performance obligations in the contract; and (5) recognizing revenue when, or as, we satisfy performance obligations by transferring the promised goods or services.

Accounts Receivable and Allowance for Doubtful Accounts - Trade accounts receivable are carried at original invoice amount less an estimate made for doubtful
accounts. We determine the allowance for doubtful accounts by identifying potential troubled accounts and by using historical experience and future expectations applied to an
aging of accounts. Trade accounts receivable are written off when deemed uncollectible. Recoveries of trade accounts receivable previously written off are recorded as income
when received.

Inventory Valuation - Inventories consist of raw materials used in the production of customized parts, work-in-process and finished goods components which will be
sold to customers. Inventories are valued at the lower of cost or net realizable value, using the first-in, first-out (FIFO) method. Charges for obsolete inventory are based on
specific identification of inventory items resulting from regular, on ongoing reviews of our build of materials.

Long-Lived  and  Intangible  Assets  –  Long-lived  assets  and  certain  identifiable  definite  life  intangibles  to  be  held  and  used  by  the  Company  are  reviewed  for
impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset  may  not  be  recoverable.  The  Company  continuously  evaluates  the
recoverability of its long-lived assets based on estimated future cash flows and the estimated liquidation value of such long-lived assets and provides for impairment if such
undiscounted cash flows are insufficient to recover the carrying amount of the long-lived assets. If impairment exists, an adjustment is made to write the asset down to its fair
value, and a loss is recorded as the difference between the carrying value and fair value. Fair values are determined based on quoted market values, discounted cash flows or
internal and external appraisals, as applicable. Assets to be disposed of are carried at the lower of carrying value or estimated net realizable value. Utility patents are amortized
over a 17-year period. Patents which are pending are not amortized.

Stock Based Compensation – We measure the compensation costs of share-based compensation arrangements based on the grant-date fair value and recognize the
costs in the financial statements over the period during which employees are required to provide services. Share based compensation arrangements may include stock options,
grants of shares of common stock with and without restrictions, performance-based awards, share appreciation rights and employee share purchase plans. Compensation cost is
measured on the date of grant at its fair value.

Equity instruments issued to non-employees are recorded on the basis of the grant date fair value of the instruments. In general, the measurement date is either (a)
when a performance commitment, as defined, is reached or (b) the earlier of the date that (i) the non-employee performance requirement is complete or (ii) the instruments are
vested. The measured value related to the instruments is recognized over a period based on the facts and circumstances of each particular grant.

The grant date fair value of stock based and other equity instruments is calculated using the Black Scholes valuation model, and requires estimates of several inputs to

the model, including risk-free interest rates, dividends, and expected volatility of our stock price.

Results of Operations

Year Ended December 31, 2021 Compared to the Year Ended December 31, 2020.

We generate revenues through hardware and software licensing of our PrintRite3D® technology to customers that seek to improve their manufacturing production
processes, and through ongoing annual software upgrades and maintenance fees. Additionally, we generate revenues from our contract manufacturing activities in metal AM.
Our ability to generate revenues in the future will depend on our ability to further commercialize and increase market presence of our PrintRite3D® technologies, and it will
depend on whether key prospective customers continue to move from AM metal prototyping to production.

During fiscal 2021, we made a significant investment in both our employees and our infrastructure, adding resources to be in a position to grow our business.

Employees and Headcount

We added 13 full-time employees in 2021. We increased our sales team from two at the beginning of the year to seven in an effort to expand our business. Specifically,
we  hired  a  senior  director  of  sales  in  the  US  Western  region,  an  area  sales  manager  for  the  European,  Middle  East  and  Africa  (EMEA  )  region,  and  three  technical  sales
engineers, one of whom is in Europe, to support our business development and sales efforts. We also added a total of seven engineers including three software engineers and
four  applications  engineers,  who  will  be  furthering  our  machine  learning  and  artificial  intelligence  (“AI”)  initiatives,  as  well  as  increasing  our  manufacturing  capacity  and
ability to perform customer installations and field support. Finally, in September 2021, we hired a Senior VP of Product Management and Strategic Relationships.

The  labor  market  is  extremely  competitive,  and  our  highly  trained,  skilled,  and  talented  employees  are  heavily  recruited  by  others.  To  that  end,  we  have  made
additional investments in our employees designed to ensure we remain competitive in the marketplace. This also aligns well with, and reinforces, our “employee first” culture.
In addition to salaries, we improved our benefits by offering a premium health care plan option and increasing the Company’s contribution to premiums. We have also added a
Company paid short-term disability insurance plan and optional long-term disability insurance plan. And finally, we have increased equity related compensation to everyone in
our Company, from non-employee directors to executive management to employees and consultants. We believe that this is an important component of aligning shareholder,
company, and employee interests and vests everyone in the growth and success of Sigma.

Gross Margin

In  fiscal  year  2021,  we  increased  our  gross  margin  to  66%  from  27%  in  2020.  The  primary  reasons  for  the  39%  improvement  are:  (1)  sourcing  components  from
multiple vendors has enabled us to secure alternative supply sources as well as lower material costs; (2) engineering enhancements, particularly around optics redesigns and
computing  power  and  storage,  have  lowered  costs  while  improving  unit  performance;  (3)  we  have  become  more  efficient  in  our  customer  installations,  through  the  use  of
virtual technology; (4) changes to our Rapid Test and Evaluation (“RTE”) program making them shorter in duration, with clearly defined objectives and more certain outcomes
in terms of ultimately leading to unit sales; and (5) adopting lean manufacturing principles which has improved controls, lowered costs, and improved efficiency.

Infrastructure

In addition to the investments made to improve our manufacturing processes and engineering designs, in fiscal 2021 we added new software applications to assist us in
achieving the leverage we need in our operations, both now and for the future. In particular, we added software subscriptions for a customer relationship management system
(CRM”), a product lifecycle management system (“PLM”), and a project tracking and management system, all of which we believe will help us improve controls, efficiency
and communication throughout the Company.

Revenue and Cost of Revenue

During the fiscal year ended December 31, 2021 (“fiscal 2021”), we generated an aggregate of $1,651,765 in revenues, as compared to an aggregate of $807,488 in
revenues generated by us in the fiscal year ended December 31, 2020 (“fiscal 2020”). The contributors to the $844,277 increase were: (1) increased new PrintRite3D® system
sales of $888,954; (2) increased on-site engineering and installation revenues of $26,200; and (3) increased annual maintenance revenues of $12,402, partially offset by (1) a
decrease in revenues from our Rapid Test and Evaluation (“RTE”) program of $82,064; and (2) decreased revenue from contract AM jobs of $1,215. Our cost of revenue for
fiscal 2021 was $559,965 compared to $591,957 during the same period in 2020, a decrease of $31,992. The decrease is primarily due to a decrease in RTE program expenses
and  a  decrease  in  the  cost  of  manufacturing  PrintRite  3D  units  through  the  aforementioned  combination  of  lower  component  costs,  engineering  redesign  and  increased
manufacturing  efficiency,  partially  offset  by  increase  in  the  cost  of  revenues  due  to  increased  sales  volume  in  2021.  The  Company  sold  11  PrintRite3D  units  in  2021  as
compared to 6 units in 2020.

Operating Expenses

Sigma’s operating expenses for fiscal 2021 were $9,571,185 as compared to $5,914,299 for fiscal 2020, a $3,656,886 increase.

In fiscal 2021, salaries and benefits costs were $4,286,368 as compared to $2,622,162 for the same period in fiscal 2020. The $1,664,206 increase is comprised of: (a)
$657,298  related  to  the  hire  of  13  additional  employees;  (b)  $486,168  related  to  salary  increases  for  existing  employees;  (c)  increased  incentive  bonuses  of  $179,250;  (d)
increased  commissions  of  $57,580  as  a  result  of  increased  sales  in  2021;  (e)  increased  taxes  and  benefits  of  $244,977;  and  (f)  increased  severance  of  $50,793.  Partially
offsetting these increases was a decrease in stock appreciation rights expense of $12,355 due to the year-end revaluation of the compensation liability.

Stock-based compensation for fiscal 2021 was $1,066,455 compared to $596,842 for the same period in fiscal 2020. This $469,613 increase resulted primarily from
options  granted  to  our  new  Senior  Vice  President  of  Product  Management  and  Strategic  Relationships  of  $264,352,  initial  options  granted  to  13  new  employees  totaling
$56,123, and annual option grants to existing employees totaling $149,138.

During fiscal 2021 and 2020, Sigma incurred operations and research and development expenditures of $890,553 and $351,404 respectively. Of the total expense in
2021, $417,744 related to research and development and $472,809 related to operations expenses. Of the total expense in 2020, $126,292 related to research and development
and $225,112 related to operations expenses. The increase of $291,452 in research and development costs in 2021 is primarily related to: (a) costs incurred in connection with
PrintRite3D  version  7.0  of  $89,798  and  $20,977  for  PrintRite3D  8.0;  (b)  an  increase  in  CT  scans  conducted  for  new  development  work  and  a  simulation  project  totaling
$87,988; (c) increased consulting expense related to our optics redesign of $67,189; and (d) $25,500 of expenses related to upgrading the date acquisition component of the
PrintRite3D unit (“DAQ”). Operations expenses in fiscal year 2021 increased $247,698 from 2020, primarily due to: (a) increased purchases of lab supplies and equipment of
$129,617; (b) write offs of three returned RTE systems with unusable parts of $34,273; and (c) write-off of metal powder and obsolete inventory of $111,158. These increases
were partially offset by a decrease in consulting costs of $27,350 due to the full time hire of a consultant in 2021

Sigma’s  investor  and  public  relation  fees  incurred  in  fiscal  2021  were  $503,823,  compared  to  $408,717  in  fiscal  2020.  The  $95,106  increase  in  the  comparative
expenditures results primarily from an increase in IR consulting costs of $48,847, and increased tradeshow and conference expenses of $90,548 based on increased attendance
due to reduced COVID restrictions, partially offset by decreased advertising expenses of $44,316 due to discontinuation of our public relations firm and Network Newswire
services.

Organizational costs for fiscal 2021 were $726,147, compared to $451,982 for the same period in fiscal 2020. The increase of $274,165 is primarily attributable to

increased directors compensation, consisting of stock options expense of $298,706 partially offset by lower cash compensation of $22,717.

Legal and professional service fees in fiscal 2021 were $915,530 compared to $676,142 in fiscal 2020. The increase of $239,388 is primarily attributable to an increase
in recruiting fees of $169,978 related to 9 of our 13 new hires, an increase in IT services fees of $10,814, and an increase in consulting fees of $64,494 due to the engagement
of external HR, accounting, and manufacturing consultants as well as increased compensation for a consultant to our CEO of $72,000. These amounts were partially offset by
reduced legal fees of $83,669 due to non-recurring expenses incurred in 2020, including expenses related to Nasdaq compliance, our reverse stock split, and an abandoned
financing.

During fiscal 2021, Sigma’s office expenses were $734,386 compared to $416,580 in the same period of fiscal 2020. The $317,806 increase in these expenditures
resulted primarily from: (a) increased payroll service fees of $18,314 due to 4 months of free service in 2020; (b) increased postage of $45,644 due to RTE returns, shipping
PrintRite3D units to trade shows, and expedited shipping of parts and materials due to increased lead times; (c) an increase in computer hardware and office supplies of $40,171
due  to  the  purchase  of  computers  for  new  hires,  promotional  items,  and  cleaning,  sanitary  and  safety  supplies  related  to  COVID  pandemic;  (d)  an  increase  in  dues  and
subscriptions expense of $50,330 for new customer relationship management, product lifecycle management, and project management software; (e) increased travel expenses
of $148,507 due to virtually no travel in 2020 as a result of COVID 19 restrictions; and (f) an increase in training and education expense of $15,059 for cable manufacturing
certification and employee team building exercises.

Other operating expenses for fiscal 2021 totaled $353,818, compared to $285,295 for fiscal 2020. The increase of $68,523 is primarily due to an increase in insurance

premiums, in particular our director’s & officer’s policy premium.

In fiscal 2021, our net other income & expense was net income of $1,094,780, compared to net income of $498,629 in fiscal 2020. The increase of $596,151 was
primarily due to a gain on the derivative liability of $1,092,441, as compared to the 2020 State of New Mexico’s high wage tax credit incentive program of $151,656, as well as
the Payroll Protection Plan loan forgiveness of $361,700.

Sigma’s net loss before preferred dividends for fiscal 2021 increased by $2,184,466 and totaled $7,384,605, as compared to a net loss before preferred dividends of
$5,200,139 for fiscal 2020. Net loss applicable to common stockholders for fiscal 2021 was $7,488,172, as compared to $7,009,414 for fiscal 2020. The 2021 net operating loss
component of the overall loss being $2,768,405 higher than in 2020 and the other income component being a $596,151 higher. Preferred stock dividends were $103,567 in
fiscal 2021 and $1,809,275 in fiscal 2020.

Liquidity and Capital Resources

As  of  December  31,  2021,  we  had  $11,447,047  in  cash  and  working  capital  of  $11,702,358,  as  compared  to  $3,700,814  in  cash  and  working  capital  of  $4,332,053  as  of
December 31, 2020.

We believe that our existing cash on hand will be sufficient to fund our anticipated operating costs and capital expenditure requirements through 2022. We have based

this estimate on assumptions that may prove to be wrong, and we could exhaust our capital resources sooner than we expect.

Because of the numerous risks and uncertainties associated with the research, development, and commercialization of our products, we are unable to estimate the exact

amount of our working capital requirements. Our future capital requirements will depend on many factors, including:

● The cost of expending, maintaining, and enforcing our intellectual property portfolio, including filing, prosecuting, defending and enforcing our patent claims and

other intellectual property rights;

● The effect of competing technological and market developments;
● The revenue from the sales of our existing and future products;
● The cost of operating as a public company; and
● The other factors listed under Item 1A “Risk Factors.”

Our  major  sources  of  funding  have  been  proceeds  from  public  and  private  offerings  of  our  equity  securities  (both  common  stock  and  preferred  stock),  and  from
warrant exercises. In January 2021, the Company closed a public offering of 1,711,783 shares of common stock at $3.00 per share, resulting in net proceeds of approximately
$4,532,444  after  deducting  underwriting  discounts  and  commissions  and  other  offering  expenses  payable  by  the  Company.  In  March  2021,  the  Company  closed  a  public
offering of 2,190,000 shares of common stock at $4.445 per share, resulting in net proceeds to the Company of approximately $8,736,488 after deducting placement agent
commissions and other offering costs payable by the Company. Concurrent with the public offering, the Company issued warrants to investors to purchase an aggregate of
2,190,000 shares of common stock to holders in a private placement. The warrants entitle the holders to purchase one share of our common stock at an exercise price equal to
$4.32 per share commencing on May 24, 2021 and will expire two years from such date.

During the first quarter of 2021, the Company issued 454,404 shares of common stock pursuant to the exercise of warrants, resulting in net proceeds to the Company

of $1,136,010.

We will need to raise additional amounts to fund our operations, maintain compliance with the NASDAQ listing requirements and implement our business plan. There
is no assurance as to the amount and availability of any required future financing or the terms thereof. Such financing, if in the form of equity, may be highly dilutive to our
existing stockholders and may otherwise include onerous terms. If in the form of debt, such financing may include covenants and repayment obligations which may be difficult
to meet and that could adversely affect our business operations. There is also significant uncertainty from the affect that the novel coronavirus may have on the availability and
type of financing. To the extent that funds are not available to us, we may be required to delay, limit, or terminate our business operations and lose our NASDAQ listing.

During  2022,  we  expect  to  sustain  our  operations  and  our  commercialization  and  marketing  efforts  with  our  cash  reserves  and  revenues  generated  from  sales  of  our
PrintRite 3D® technology. We expect that continued enhancements of our IPQA®-enabled PrintRite3D® technology will enable us to further commercialize this technology
into the AM metal market in 2022. To support the commercialization of our PrintRite3D® technology, we plan to continue funding our development activities and operating
expenses by licensing our PrintRite3D® systems and supporting field services, as applicable, and providing PrintRite3D®-enabled engineering consulting services concerning
our  areas  of  expertise  (materials  and  manufacturing  quality  assurance  and  process  control  technologies)  and  through  the  use  of  proceeds  from  sales  of  our  securities  and
potential exercises of our outstanding warrants.

Net Cash Used in Operating Activities

Net cash used in operating activities in fiscal 2021 increased to $6,298,959 from $4,809,868 in fiscal 2020. This increase was primarily attributable to: (1) an increase in
our net loss before preferred dividends of $2,184,466; (2) the gain on the derivative liability of $1,092,441; (3) a decrease in depreciation expense of $11,070; (4) a decrease in
current and long-term prepaid assets of 132,534; and (5) a decrease in deferred payroll taxes under the CARES Act of $37,728 due to repayment of 50% of the total deferral in
December 2021. Partially offsetting these increases were: (1) higher equity-based compensation expenses of $828,623 due to: (a) increased options and common share grants
awarded to employees of $469,613; (b) increased stock options granted to consultants in lieu of cash of $60,308, and (c) increased equity based compensation for directors of
$298,702; (2) a decrease in accounts receivable of $195,392 due to increased cash collections from higher sales volume; (3) a decrease in inventory in 2021 from 2020 of
$10,503;  (4)  an  increase  in  accounts  payable  and  other  accrued  expenses  of  $802,242  primarily  due  to  (a)  $196,071  of  increased  year  end  compensation  accruals;  (b)  an
increase in SAR’s liability of $93,926; (c) increased trade accounts payable of $77,245; (d) additional professional services fee accruals of $35,000; (e) approximately $400,000
of  payments  made  in  fiscal  2020  related  to  fiscal  2019  payables  following  closing  of  our  January  and  April  2020  financings;  and  (5)  an  increase  in  deferred  revenue  of
$132,388

Net Cash Used by Investing Activities

Net cash used by investing activities during fiscal 2021 was $359,750, which compares to cash used by investing activities during 2020 totaling $298,359. The increase
was primarily due to increased purchases of fixed assets of $94,448, the most significant of which was the purchase of a new laser for our 3D metal printer of $63,000, partially
offset by lower costs incurred for patents of $33,557.

Net Cash Provided by Financing Activities

Cash provided by financing activities during fiscal 2021 increased to $14,404,942 from $8,722,122 during the same period in 2020, an increase of $5,682,820 primarily
as  a  result  of  higher  net  proceeds  from  our  2021  financings  as  compared  to  2020  of  $10,489,160,  partially  offset  by  lower  proceeds  from  exercise  of  warrants  in  2021  of
$4,856,340.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Rule 13a-15(e) under the Exchange Act defines the term “disclosure controls and procedures” as those controls and procedures designed to ensure that information
required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods
specified in the SEC rules and forms and that such information is accumulated and communicated to the company’s management, including its principal executive and principal
financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based upon an evaluation of the effectiveness of our disclosure controls and procedures performed by our management, with the participation of our Chief Executive
Officer, and Chief Financial Officer (Principal Financial and Accounting Officer), as of the end of the period covered by this annual report, our management concluded that our
disclosure controls and procedures are effective at a reasonable assurance level in ensuring that information required to be disclosed by us in our reports is recorded, processed,
summarized and reported within the required time periods. The foregoing conclusion is based, in part, on the fact that we are a small public company with limited revenues and
employees.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f)
under the Exchange Act. Our management, with the participation of our Chief Executive Officer, and Chief Financial Officer, conducted an evaluation of the effectiveness of
our control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission.  Based  on  management’s  evaluation  under  the  framework,  management  has  concluded  that  our  internal  control  over  financial  reporting  was  effective  as  of
December 31, 2021.

We  continuously  seek  to  improve  and  strengthen  our  control  processes  to  ensure  that  all  of  our  controls  and  procedures  are  adequate  and  effective.  Any  failure  to
implement  and  maintain  improvements  in  the  controls  over  our  financial  reporting  could  cause  us  to  fail  to  meet  our  reporting  obligations  under  the  SEC’s  rules  and
regulations. Any failure to improve our internal controls to address the weakness we have identified could also cause investors to lose confidence in our reported financial
information, which could have a negative impact on the trading price of our common stock.

growth strategies, enterprise sales, business acquisitions, as well as his background and extensive company management and leadership experience.

Director Independence

Our Board of Directors currently consists of five members. As a result of his previous role as Chief Executive Officer, Mr. Rice is not considered an independent
director.  As  a  result  of  his  April  30,  2020  appointment  as  Chief  Executive  Officer,  Mr.  Ruport  is  also  not  considered  an  independent  director.  Our  Board  of  Directors  has
determined that our other directors, Salvatore Battinelli, Dennis Duitch and Kent Summers, constituting a majority of our directors, are “independent” as that term is defined
under Rule 5605(a)(2) of the NASDAQ marketplace rules. Pursuant to NASDAQ rules, our board must consist of a majority of independent directors.

The  NASDAQ  independence  definition  includes  a  series  of  objective  tests,  including  that  the  director  is  not,  and  has  not  been  for  at  least  three  years,  one  of  our
employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by NASDAQ rules,
our Board of Directors has made a subjective determination as to Messrs. Battinelli, Duitch and Summers, our independent directors, that no relationships exist, which, in the
opinion of our Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations,
our Board of Directors reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as
they may relate to us and our management. There are no family relationships among any of our directors or executive officers.

Classified Board of Directors

In accordance with our amended and restated bylaws, our Board of Directors is divided into three classes with staggered, three-year terms. At each annual meeting of
stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following
election. Our directors are classified as follows:

● the Class I directors are John Rice and Mark Ruport, with terms expiring at our 2024 annual meeting of stockholders;

● the Class II director is Salvatore Battinelli, with a term expiring at our 2022 annual meeting of stockholders; and

● the Class III directors are Dennis Duitch and Kent Summers, with terms expiring at our 2023 annual meeting of stockholders.

Our  amended  and  restated  bylaws  provide  that  the  authorized  number  of  directors  may  be  changed  by  resolution  of  the  Board  of  Directors.  Any  additional
directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third
of the directors. The division of our Board of Directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in
control of our company.

Our directors may be removed with or without cause at any meeting of stockholders by the affirmative vote of the holders of at least two-thirds of our outstanding
voting stock entitled to vote in the election of directors. Our amended and restated bylaws provide our Board of Directors with flexibility in its discretion to combine or separate
the positions of Chairman of the Board and Chief Executive Officer, if we elect to appoint a Chairman of the Board. Our Board of Directors believes it is important to select the
Company’s Chairman and Chief Executive Officer in the manner it considers in the best interests of the Company at any given time. Our Board of Directors believes that the
Chairman  and  Chief  Executive  Officer  positions  may  be  filled  by  one  individual  or  by  two  different  individuals,  as  determined  by  our  Board  of  Directors  based  on
circumstances then in existence.

On August  19,  2017,  our  Board  of  Directors  appointed  Mr.  Rice  as  Chairman  of  the  Board.  The  Chairman  of  the  Board  presides  at  all  meetings  of  our  Board  of
Directors  and  exercises  and  performs  such  other  powers  and  duties  as  may  be  assigned  to  him  from  time  to  time  by  the  Board  or  prescribed  by  our  amended  and  restated
bylaws. The Chairman of the Board is appointed by our Board of Directors on an annual basis.

Our Board of Directors has no established policy on whether it should be led by a Chairman who is also the Chief Executive Officer, and has in the past combined the
roles  of  Chairman  and  Chief  Executive  Officer.  Our  Board  currently  is  committed  to  the  separated  roles  given  the  circumstances  of  our  Company.  However,  our  Board  of
Directors continually evaluates our leadership structure and could, in the future, decide to combine the Chairman and Chief Executive Officer positions if it believes that doing
so would serve the best interests of our Company and our stockholders.

Board Meetings and Committees

During our fiscal year ended December 31, 2021, the Board of Directors held eight meetings, and each director attended at least 75% of the aggregate of (i) the total
number of meetings of our Board of Directors held during the period for which he has been a director and (ii) the total number of meetings held by all committees of our Board
of Directors on which he served during the periods that he served.

Although we do not have a formal policy regarding attendance by members of our Board of Directors at annual meetings of stockholders, we encourage, but do not

require, our directors to attend. Each of our then current directors attended our 2021 Annual Meeting of Stockholders.

Our Board has established three standing committees-audit, compensation, and nominating and corporate governance-each of which operates under a written charter
that has been approved by our board. Until February 15, 2017, when our common stock became listed on The Nasdaq Capital Market, we were not required to establish or
maintain an audit, nominating or compensation committee. Each committee charter has been posted on the Investors section of our website at www.sigmalabsinc.com. The
reference to our website address does not constitute incorporation by reference of the information contained at or available through our website, and you should not consider it
to be a part of this Annual Report.

Code of Ethics and Business Conduct

The  Company  has  a  code  of  ethics  that  applies  to  all  employees,  including  the  Company’s  principal  executive  officer,  principal  financial  officer,  and  principal
accounting officer, as well as to the members of the Board of Directors. The code is available at www.sigmalabsinc.com. The Company intends to disclose any changes in, or
waivers from, this code by posting such information on the same website or by filing a Form 8-K, in each case to the extent such disclosure is required by rules of the SEC or
Nasdaq. The reference to our website address does not constitute incorporation by reference of the information contained at or available through our website, and you should
not consider it to be a part of this report.

Considerations in Evaluating Director Nominees

Our  Nominating  and  Corporate  Governance  Committee  uses  a  variety  of  methods  for  identifying  and  evaluating  director  nominees.  In  its  evaluation  of  director
candidates,  our  Nominating  and  Corporate  Governance  Committee  will  consider  the  current  size  and  composition  of  our  Board  of  Directors  and  the  needs  of  our  Board  of
Directors and the respective committees of our Board of Directors. Some of the qualifications that our Nominating and Corporate Governance Committee considers include,
without limitation, issues of character, integrity, judgment, diversity of experience, independence, area of expertise, corporate experience, length of service, potential conflicts
of interest and other commitments. Nominees must also have the ability to offer advice and guidance to our Chief Executive Officer based on past experience in positions with
a  high  degree  of  responsibility  and  be  leaders  in  the  companies  or  institutions  with  which  they  are  affiliated.  Director  candidates  must  have  sufficient  time  available  in  the
judgment of our Nominating and Corporate Governance Committee to perform all board of director and committee responsibilities. Members of our Board of Directors are
expected to prepare for, attend, and participate in all board of director and applicable committee meetings. Other than the foregoing, there are no stated minimum criteria for
director nominees, although our Nominating and Corporate Governance Committee may also consider such other factors as it may deem, from time to time, are in our and our
stockholders’ best interests.

Although our Board of Directors does not maintain a specific policy with respect to board diversity, our Board of Directors believes that our Board of Directors should
be a diverse body, and our Nominating and Corporate Governance Committee considers a broad range of backgrounds and experiences. In making determinations regarding
nominations  of  directors,  our  Nominating  and  Corporate  Governance  Committee  may  take  into  account  the  benefits  of  diverse  viewpoints.  Our  Nominating  and  Corporate
Governance  Committee  also  will  consider  these  and  other  factors  as  it  oversees  the  annual  board  of  director  and  committee  evaluations.  After  completing  its  review  and
evaluation of director candidates, our Nominating and Corporate Governance Committee recommends to our full Board of Directors the director nominees for selection.

Stockholder Recommendations for Nominations to the Board of Directors

Our Nominating and Corporate Governance Committee will consider candidates for director recommended by stockholders so long as such recommending stockholder
was a stockholder of record both at the time of giving notice and at the time of the annual meeting, and such recommendations comply with our amended and restated articles
of  incorporation  and  amended  and  restated  bylaws  and  applicable  laws,  rules  and  regulations,  including  those  promulgated  by  the  SEC.  The  Nominating  and  Corporate
Governance  Committee  will  evaluate  such  recommendations  in  accordance  with  its  charter,  our  amended  and  restated  bylaws,  our  policies  and  procedures  for  director
candidates,  as  well  as  the  regular  director  nominee  criteria  described  above.  This  process  is  designed  to  ensure  that  our  Board  of  Directors  includes  members  with  diverse
backgrounds, skills and experience, including appropriate financial and other expertise relevant to our business. Eligible stockholders wishing to recommend a candidate for
nomination  should  contact  the  Secretary  in  writing.  Our  Nominating  and  Corporate  Governance  Committee  has  discretion  to  decide  which  individuals  to  recommend  for
nomination as directors.

Role of Board in Risk Oversight Process

Risk assessment and oversight are an integral part of our governance and management processes. Our Board of Directors encourages management to promote a culture
that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management
meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks we face. Throughout the year,
senior management reviews these risks with the Board of Directors at regular board meetings as part of management presentations that focus on particular business functions,
operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks. Our Board of Directors does not have a standing risk management
committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through standing committees of the Board of Directors
that will address risks inherent in their respective areas of oversight. In particular, our Audit Committee is responsible for overseeing our major financial risk exposures and the
steps our management has taken to monitor and control these exposures. The Audit Committee also monitors compliance with legal and regulatory requirements and considers
and approves or disapproves any related-person transactions. Our Nominating and Governance Committee monitors the effectiveness of our corporate governance guidelines
that we may adopt or amend from time to time. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential
to encourage excessive risk-taking by our management.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s executive officers and directors, and persons who own more than 10% of a registered
class of the Company’s equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission (“SEC”). Executive officers,
directors and greater than 10% stockholders are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file.

The Company believes that during the fiscal year ended December 31, 2021, its executive officers, directors and greater than 10% stockholders complied with the

filing requirements under Section 16(a).

ITEM 11. EXECUTIVE COMPENSATION

Processes and Procedures for Compensation Decisions

Our  Compensation  Committee  is  responsible  for  the  executive  compensation  programs  for  our  executive  officers  and  reports  to  our  board  of  directors  on  its
discussions, decisions and other actions. Typically, our Chief Executive Officer makes recommendations to our Compensation Committee and is involved in the determination
of compensation for the respective executive officers that report to him. Our Chief Executive Officer does not determine his own compensation. Our Chief Executive Officer
makes recommendations to our Compensation Committee regarding short- and long-term compensation for all executive officers based on our results, an individual executive
officer’s contribution toward these results and performance toward individual goal achievement. Our Compensation Committee then reviews the recommendations and other
data and makes decisions (or makes recommendations to the Board) as to total compensation for each executive officer as well as each individual compensation component.

Officer at any time during the past fiscal year, and (ii) for our two most highly compensated executive officers, other than our Chief Executive Officer, who were employed

Named Executive Officer Employment Agreements

Mark K Ruport

On December 3, 2019, we entered into an “at-will’ employment letter agreement with Mark Ruport, effective as of December 3, 2019 (the “effective date”), pursuant
to which Mr. Ruport agreed to serve as our Executive Chairman on an “at-will” basis. Additionally, Mr. Ruport was appointed to serve as a member of our Board of Directors,

rights (“SARs”) payable in cash. No shares of common stock were reserved in connection with the adoption of the Plan since no shares will be issued pursuant to the Plan.
Awards issued under the Plan are included in the table.

Equity Awards

We offer stock options, stock appreciation rights, and stock awards to certain of our employees, including our executive officers, as the long-term incentive component
of our compensation program. We generally grant equity awards to new hires upon their commencing employment with us. Our stock options allow employees to purchase
shares of our common stock at a price per share equal to the fair market value of our common stock on the date of grant and may or may not be intended to qualify as “incentive
stock options” for U.S. federal income tax purposes. Our stock appreciation rights allow employees to receive a cash payment for the difference between the market price of our
common stock on the date of exercise and the strike price. We sometimes also offer stock options, stock appreciation rights and stock awards to our consultants in lieu of cash.
Our stock options allow consultants to purchase shares of our common stock at a price per share equal to the fair market value of our common stock on the date of grant and are
not intended to qualify as “incentive stock options” for U.S. federal income tax purposes. Our stock appreciation rights allow consultants to receive a cash payment for the
difference between the market price of our common stock on the date of exercise and the strike price. Stock options, stock appreciation rights, and stock awards granted to our
executive officers may be subject to accelerated vesting in certain circumstances.

Retirement Plans

We  maintain  a  qualified  401(k)  plan,  in  which  all  eligible  employees  may  participate.  We  make  safe  harbor  contributions  to  match  100%  of  each  participant’s
contribution up to 3% of salary, and 50% of the next 2% of salary contributed. Safe harbor contributions are 100% vested. We may also elect, on an annual basis, to make a
discretionary contribution to the plan, but have not done so to date. Our elective matches and elective contributions vest to participant accounts as follows: 20% after two years
of service, and 20% per year thereafter until the participant reaches 6 years of service, at which time, employer contributions vest 100%. As a tax-qualified retirement plan,
contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan.

No Tax Gross-Ups

 
 
 
 
 
 
 
 
 
 
We  do  not  make  gross-up  payments  to  cover  our  executive  officers’  personal  income  taxes  that  may  pertain  to  any  of  the  compensation  paid  or  provided  by  our

company.

2013 Equity Incentive Plan

Plan Purpose

Our Board of Directors adopted the 2013 Plan to (1) encourage selected employees, officers, directors, consultants and advisers to improve our operations and increase
our profitability, (2) encourage selected employees, officers, directors, consultants and advisers to accept or continue employment or association with us, and (3) increase the
interest of selected employees, officers, directors, consultants and advisers in our welfare through participation in the growth in value of our common stock. All of our current
employees, directors and consultants are eligible to participate in the 2013 Plan.

Administration

The 2013 Plan is to be administered by the Board or by a committee to which administration of the Plan, or of part of thereof, is delegated by the Board. The 2013
Plan is currently administered by our Compensation Committee, which we refer to below as the “Administrator.” The Administrator is responsible for selecting the officers,
employees, directors, consultants and advisers who will receive Options, Stock Appreciation Rights and Stock Awards. Subject to the requirements imposed by the 2013 Plan,
the Administrator is also responsible for determining the terms and conditions of each Option and Stock Appreciation Right award, including the number of shares subject to
the  Option,  the  exercise  price,  expiration  date  and  vesting  period  of  the  Option  and  whether  the  option  is  an  Incentive  Option  or  a  Non-Qualified  Option.  Subject  to  the
requirements imposed by the 2013 Plan, the Administrator is also responsible for determining the terms and conditions of each Stock Award, including the number of shares
granted, the purchase price (if any), and the vesting, transfer and other restrictions imposed on the stock. The Administrator has the power, authority and discretion to make all
other determinations deemed necessary or advisable for the administration of the 2013 Plan or of any award under the 2013 Plan.

Neither the Board nor any committee of the Board to which administration of the 2013 Plan is delegated will provide advice to participants about whether or not to

accept or exercise their awards. Each participant must make his or her own decision about whether or not to accept or exercise an award.

The 2013 Plan is not subject to the Employee Retirement Income Security Act of 1974 and is not a qualified pension, profit sharing or bonus plan under Section 401(a)

of the Internal Revenue Code

Stock Subject to the 2013 Plan

As of March 23, 2022, there were 1,473,297 shares previously issued or subject to outstanding awards under the 2013 Plan and 262,262 shares were available for

future issuance under the 2013 Plan.

If awards granted under the 2013 Plan expire or otherwise terminate or are cancelled without being exercised in full, the shares of common stock not acquired pursuant
to such awards will again become available for issuance under the 2013 Plan. If shares of common stock issued pursuant to awards under the 2013 Plan are forfeited to or
repurchased by us, the forfeited or repurchased stock will again become available for issuance under the 2013 Plan.

If shares of common stock subject to an award are not delivered to a participant because such shares are withheld for payment of taxes incurred in connection with the
exercise of an Option, or the issuance of shares under a Stock Award, or the award is exercised through a reduction of shares subject to the award (“net exercised”), then the
number of shares that are not delivered will not again be available for issuance under the 2013 Plan. In addition, if the exercise price of any award is satisfied by the tender of
shares of common stock to us (whether by actual delivery or attestation), the shares tendered will not again be available for issuance under the 2013 Plan.

Eligibility

All directors, employees, consultants and advisors of the Company and its subsidiaries are eligible to receive awards under the 2013 Plan. Incentive Options may only
be granted under the 2013 Plan to a person who is a full-time officer or employee of the Company or a subsidiary. The Administrator will determine from time-to-time which
directors, employees, consultants and advisers will be granted awards under the 2013 Plan.

Terms of Awards

Written Agreement

Each award under the 2013 Plan will be evidenced by an agreement in a form approved by the Administrator.

Exercise Price; Base Value

The exercise price for a Non-Qualified Option or an Incentive Option may not be less than 100% of the fair market value of the Common Stock on the date of the
grant of the Non-Qualified Option or Incentive Option. With respect to an Option holder who owns stock possessing more than 10% of the total voting power of all classes of
our stock, the exercise price for an Incentive Option may not be less than 110% of the fair market value of the Common Stock on the date of the grant of the Incentive Option.
The base value of a Stock Appreciation Right shall also be no less than 100% of the Common Stock on the date of the grant of the Stock Appreciation Right. The 2013 Plan
does not specify a minimum exercise price for Stock Awards.

Vesting

Each Option, Stock Appreciation Right or Stock Award will become exercisable or non-forfeitable (that is, “vest”) under conditions specified by the Administrator at
the time of grant. Vesting typically is based upon continued service as a director or employee but may be based upon any performance criteria and other contingencies that are
determined by the Administrator. Shares subject to Stock Awards may be subject to specified restrictions concerning transferability, repurchase by the Company and forfeiture
of the shares issued, together with such other restrictions as may be determined by the Administrator.

Expiration Date

Each Option or Stock Appreciation Right must be exercised by a date specified in the award agreement, which may not be more than ten years after the grant date.
Except  as  otherwise  provided  in  the  relevant  agreement,  an  Option  or  Stock  Appreciation  Right  ceases  to  be  exercisable  ninety  days  after  the  termination  of  the  holder’s
employment with us.

Transfers of Options

Unless otherwise determined by the Administrator, Options are not transferable except by will or the laws of descent and distribution.

Purchase Price Payment

Unless otherwise determined by the Administrator, the purchase price of common stock acquired under the 2013 Plan is payable by cash or check at the time of an
Option exercise or acquisition of a Stock Award. The Company does not charge participants any fees or commissions in connection with their acquisition of common stock
under the 2013 Plan. The Administrator also has discretion to accept the following types of payment from participants:

● A secured or unsecured promissory note, provided that this method of payment is not available to a participant who is a director or an executive officer;

● Shares of  our  Common  Stock  already  owned  by  the  Option  or  Stock  Award  holder  as  long  as  the  surrendered  shares  have  a  fair  market  value  that is equal to the

acquired stock and have been owned by the participant for at least six months;

● The surrender of shares of Common Stock then issuable upon exercise of an Option; and

● A “cashless” option exercise in accordance with applicable regulations of the SEC and the Federal Reserve Board.

Withholding Taxes

At the time of his or her exercise of an Option or Stock Appreciation Right, an employee is responsible for paying all applicable federal and state withholding taxes. A
holder of Stock Awards is responsible for paying all applicable federal and state withholding taxes once the shares covered by the award cease to be forfeitable or at any other
time required by applicable law.

Securities Law Compliance

Shares of common stock will not be issued pursuant to the exercise of an Option or the receipt of a Stock Award unless the Administrator determines that the exercise
of the Option or receipt of the Stock Award and the issuance and delivery of such shares will comply with all relevant provisions of law, including, without limitation, the
Securities Act of 1933 (the “Securities Act”), applicable state and foreign securities laws and the requirements of any stock exchange on which our Common Stock is traded.

Effects of Certain Corporate Transactions

Except as otherwise determined by the Administrator, in the event of a “corporate transaction,” all previously unexercised Options and Stock Appreciation Rights will
terminate immediately prior to the consummation of the corporate transaction and all unvested Restricted Stock awards will be forfeited immediately prior to the consummation
of  the  corporate  transaction.  The  Administrator,  in  its  discretion,  may  permit  exercise  of  any  Options  or  Stock  Appreciation  Rights  prior  to  their  termination,  even  if  those
awards would not otherwise have been exercisable, or provide that outstanding awards will be assumed or an equivalent Option or Stock Appreciation Right substituted by a
successor  corporation.  The  Administrator,  in  its  discretion,  may  remove  any  restrictions  as  to  any  Restricted  Stock  awards  or  provide  that  all  outstanding  Restricted  Stock
awards  will  participate  in  the  corporate  transaction  with  an  equivalent  stock  substituted  by  the  successor  corporation  subject  to  the  restrictions.  In  general,  a  “corporate
transaction” means:

● Our liquidation or dissolution;

● Our merger or consolidation with or into another corporation as a result of which we are not the surviving corporation;

● A sale of all or substantially all of our assets; or

● A purchase or other acquisition of more than 50% of our outstanding stock by one person, or by more than one person acting in concert.

Other Adjustment Provisions

If  the  stock  of  the  Company  is  changed  by  reason  of  a  stock  split,  reverse  stock  split,  stock  dividend,  recapitalization,  combination  or  reclassification,  appropriate
adjustments shall be made by the Administrator, in its discretion, in (1) the number and class of shares of stock subject to the 2013 Plan and each Option and grant of Stock
Awards outstanding under the 2013 Plan, and (2) the purchase price of each outstanding Option and (if applicable) Stock Award.

Amendment or Termination of the Plan

The Board of Directors may at any time amend, discontinue or terminate the 2013 Plan. With specified exceptions, no amendment, suspension or termination of the
Plan  may  adversely  affect  outstanding  Options  or  Stock  Appreciation  Rights  or  the  terms  that  are  applicable  to  outstanding  Stock  Awards.  No  amendment,  suspension  or
termination of the Plan requires stockholder approval unless such approval is required under applicable law or under the rules of any stock exchange on which our Common
Stock is traded. Unless terminated earlier by the Board of Directors, the 2013 Plan will terminate automatically on March 15, 2023, which is the tenth anniversary of the date of
the 2013 Plan’s adoption by the Board.

2020 Stock Appreciation Rights Plan

On June 23, 2020, our Board of Directors adopted the Sigma Labs, Inc. 2020 Stock Appreciation Rights Plan (the “Plan”). The purposes of the Plan are to: (i) enable
the  Company  to  attract  and  retain  the  types  of  employees,  consultants,  and  directors  (collectively,  “Service  Providers”)  who  will  contribute  to  the  Company’s  long-range
success; (ii) provide incentives that align the interests of Service Providers with those of the shareholders of the Company; and (iii) promote the success of the Company’s
business. The Plan only provides for incentive awards that are only made in the form of stock appreciation rights payable in cash (“SARs”). No shares of common stock were
reserved in connection with the adoption of the Plan since no shares will be issued pursuant to the Plan.

Governance of the Plan

The Plan will be administered by the Compensation Committee of the Board or, in the Board’s sole discretion, by the Board. The Compensation Committee will have
the  authority  to,  among  other  things,  (i)  construe  and  interpret  the  Plan  and  apply  its  provisions;  (ii)  promulgate,  amend,  and  rescind  rules  and  regulations  relating  to  the
administration of the Plan; (iii) delegate its authority to one or more persons who is an officer of the Company within the meaning of Section 16 of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder with respect to SARs that do not involve “insiders” within the meaning of
Section 16 of the Exchange Act; (iv) determine when SARs are to be granted under the Plan and the applicable grant date; (v) prescribe the terms and conditions of each SAR,
including, without limitation, the exercise price and medium of payment and vesting provisions, and to specify the provisions of the SAR Agreement relating to such grant; (vi)
amend  any  outstanding  SARs,  subject,  in  certain  cases,  to  the  participant’s  consent;  and  (vii)  make  all  other  determinations  which  may  be  necessary  or  advisable  for  the
administration of the Plan.

Eligible Participants

SARS may be granted only to persons who are Service Providers, and those persons whom the Committee determines are reasonably expected to become Service
Providers following the grant date. The Committee may from time to time designate those Service Providers, if any, to be granted SARs under the Plan, the number of SARs
which will be granted to each such person, and any other terms or conditions relating to SARs as it may deem appropriate to the extent consistent with the provisions of the
Plan. A participant who has been granted a SAR may, if otherwise eligible, be granted additional incentive awards at any time.

Grant. The Committee may grant SARs to any Service Provider. A SAR is the right to receive an amount equal to the Spread with respect to a share of the Company’s
common stock upon the exercise of the SAR. The “Spread” is the difference between the exercise price per share specified in a SAR agreement on the date of grant and the fair
market value per share on the date of exercise of the SAR.

44

 
 
 
  
 
 
 
 
 
 
 
 
 
General Provisions. The terms and conditions of each SAR will be evidenced by a SAR agreement. The exercise price per share will not be less than 100% of the fair
market value of a Share on the date of grant of the SAR. The term of the SAR will be determined by the Committee but may not be greater than ten years from the date of grant.

Exercise. SARs are exercisable subject to such terms and conditions as the Committee may specify in the SAR agreement for the SAR. A SAR may be exercised by
the delivery of a signed written notice of exercise to the Company, which must be received and accepted by the Company as of a date set by the Company in advance of the
effective date of the proposed exercise. The notice must set forth the number of SARs being exercised, together with any additional documents the Company may require.

Settlement. Upon exercise of a SAR, the Grantee will receive an amount equal to the Spread. The Spread, less applicable withholdings, will be payable only in cash. In

no event may any SAR be settled in any manner other than by delivery of a cash payment from the Company.

Form of SAR Agreement

Each participant to whom a SAR is granted will be required to enter into a SAR agreement with the Company, in such a form as is provided by the Committee. The
SAR agreement will contain specific terms as determined by the Committee, in its discretion, with respect to the participant’s particular SAR. Such terms need not be uniform
among  all  participants  or  any  similarly  situated  participants.  The  SAR  agreement  may  include,  without  limitation,  vesting,  forfeiture  and  other  provisions  particular  to  the
particular participant’s SAR, as well as, for example, provisions to the effect that the participant must abide by all the terms and conditions of the Plan and such other terms and
conditions as may be imposed by the Committee. A SAR will include such terms and conditions as are determined by the Committee, in its discretion, to be appropriate with
respect to any participant.

The  Committee  may  specify  in  a  SAR  agreement  that  the  participant’s  rights,  payments,  and  benefits  with  respect  to  a  SAR  will  be  subject  to  forfeiture  upon  the
occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of the incentive award. Such events may include, but are not
limited to, termination with cause or other conduct by the participant that is detrimental to the business or reputation of the Company.

Termination of Employment

Unless otherwise expressly provided in the participant’s SAR agreement, if the participant’s employment is terminated for any reason other than due to cause, death or
disability, any non-vested portion of any outstanding SAR at the time of such termination will automatically expire and terminate and no further vesting will occur after the
termination date. In such event, except as otherwise expressly provided in the SAR agreement, the participant will be entitled to exercise such participant’s rights only with
respect to the portion of the SAR that was vested as of the termination date for a period that will end on the earlier of (i) the expiration date set forth in the SAR agreement or
(ii) ninety days after the date of termination.

Termination for Cause

Unless otherwise expressly provided in the participant’s SAR agreement, in the event of the termination of a participant’s employment for cause, all vested and non-

vested SARs granted to such participant will immediately expire, and will not be exercisable to any extent.

Disability or Death

Unless otherwise expressly provided in the participant’s SAR agreement, upon termination of employment as a result of the participant’s disability or death, (i) any
non-vested portion of any outstanding SAR will immediately terminate upon termination and no further vesting will occur, and (ii) any vested SAR will expire on the earlier of
either (A) the expiration date set forth in the SAR agreement or (B) 12 months following the participant’s termination of employment.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Continuation

Subject to the conditions and limitations of the Plan and applicable law, in the event that a participant ceases to be an employee, outside director or consultant, as
applicable, for whatever reason, the Committee and participant may mutually agree with respect to any outstanding SAR then held by the participant (i) for an acceleration or
other adjustment in any vesting schedule applicable to the SAR award; (ii) for a continuation of the exercise period following termination for a longer period than is otherwise
provided under such SAR; or (iii) to any other change in the terms and conditions of the SAR. In the event of any such change to an outstanding SAR, a written amendment to
the participant’s SAR agreement will be required. No amendment to a participant’s SAR will be made to the extent compensation payable pursuant thereto as a result of such
amendment  would  be  considered  deferred  compensation  that  is  not  excepted  from  taxation  or  penalties  under  Code  Section  409A,  unless  otherwise  determined  by  the
Committee.

SARs granted under the Plan are not transferable other than to a designated beneficiary upon the Participant’s death or by will or the laws of descent and distribution.

Change in Control

Unless otherwise provided in a SAR Agreement, notwithstanding any contrary provision in the Plan, in the event of a Change in Control (as defined in the Plan), all

outstanding SARs will become 100% vested and immediately and fully exercisable.

Amendment

The Board at any time, and from time to time, may amend or terminate the Plan. The Committee at any time, and from time to time, may amend the terms of any one
or more SAR agreements, except that the Committee may not affect any amendment which would otherwise constitute an impairment of the rights under any SAR unless the
participant consents in writing.

As of March 23, 2022, there were 412,657 SARs outstanding under the 2020 Plan.

Director Compensation

We believe that a combination of cash and equity compensation is appropriate to attract and retain the individuals we desire to serve on our Board of Directors. Our
cash compensation policies are designed to encourage frequent and active interaction between directors and our executives both during and between formal meetings as well as
compensate our directors for their time and effort. Further, we believe it is important to align the long-term interests of our non-employee directors (i.e., directors who are not
employed by us as officers or employees) with those of the Company and its stockholders, and that awarding equity compensation to, and thereby increasing ownership of our
common  stock  by,  our  non-employee  directors  is  an  appropriate  means  to  achieve  this  alignment.  Directors  who  are  also  employees  of  our  company  do  not  receive
compensation for their service on our Board of Directors.

Under our director compensation program for 2021, each non-employee director received annual compensation of $10,000, and an option to purchase 50,000 shares of
our common stock, which is fully vested. All cash fees are paid quarterly. Also, each non-employee director may be reimbursed for his reasonable expenses incurred in the
performance of his duties as a director as our Board of Directors determines from time to time. Our Compensation Committee intends to evaluate our director compensation
program and determine whether any changes should be recommended to the Board.

The following table sets forth certain information concerning the compensation paid to non-employee directors in 2021 for their services as directors of the Company.
The compensation of Mr. Ruport, who serves as a director and serves as our Chief Executive Officer, is described in the Summary Compensation Table of Executive Officers.
Our non-employee directors do not receive fringe or other benefits.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

The following table sets forth certain information regarding beneficial ownership of our common stock as of March 23, 2022 (a) by each person known by us to own
beneficially 5% or more of any class of our common stock, (b) by our named executive officers and each of our directors (and director nominees) and (c) by all executive
officers and directors of the Company as a group.

The number of shares beneficially owned by each stockholder is determined in accordance with SEC rules. Under these rules, beneficial ownership includes any shares
as to which a person has sole or shared voting power or investment power. Percentage ownership is based on 10,498,802 shares of our common stock outstanding on March 23,
2022.  In  computing  the  number  of  shares  beneficially  owned  by  a  person  and  the  percentage  ownership  of  that  person,  shares  of  common  stock  subject  to  stock  options,
warrants  or  other  rights  held  by  such  person  that  are  currently  convertible  or  exercisable  or  will  become  convertible  or  exercisable  within  60  days  of  March  23,  2022  are
considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

We  believe,  based  on  information  provided  to  us,  that  each  of  the  stockholders  listed  below  has  sole  voting  and  investment  power  with  respect  to  the  shares

beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

stockholders on October 10, 2013. On July 15, 2021, an amendment to our 2013 Equity Incentive Plan was approved by our stockholders to increase the number of shares of

(2) On June 23, 2020, our Board of Directors adopted the Sigma Labs, Inc. 2020 Stock Appreciation Rights Plan (the “Plan”). The purposes of the Plan are to: (i) enable the

interests of Service Providers with those of the shareholders of the Company; and (iii) promote the success of the Company’s business. The Plan only provides for incentive
awards that are only made in the form of stock appreciation rights payable in cash (“SARs”). No shares of common stock were reserved in connection with the adoption of the
Plan since no shares will be issued pursuant to the Plan. As of December 31, 2021, the Company has awarded 370,624 SARs pursuant to the Plan.

(3) On December 3, 2019, in conjunction with the hiring of Mark K. Ruport, the Company’s Chief Executive Officer, the Company granted to Mr. Ruport (i) an option to

to 40,000 shares of our common stock, with an exercise price of $11.20, which will vest and become exercisable in equal monthly installments over three years from the date of
grant. As of December 31, 2021, a total of 27,025 shares were vested and exercisable. In accordance with Nasdaq Listing Rule 5635(c)(4), such options were granted to Mr.

Transactions with Directors and Officers

We have entered into an “at will” employment agreement, effective as of September 20, 2021, with Jacob Brunsberg under which he was engaged to serve as our
Senior Vice President of Product Management and Strategic Relationships. On February 16, 2022, Mr. Brunsberg’s employment agreement was amended in connection with his
appointment as President and Chief Operating Officer of the Company to increase his annual base salary from $200,000 to $250,000. In addition, on February 16, 2022, Mr.
Brunsberg was granted a stock option to purchase up to 70,000 shares of common stock of the Company, at an exercise price equal to $2.50 per share under the 2013 Equity
Incentive Plan, and 30,000 stock appreciation rights (“SARs”) under the 2020 Stock Appreciation Rights Plan, at an exercise price of $2.50 each. Both the option and the SARs
vest in equal (as closely as possible) monthly installments over thirty-six months from the grant date, have five year-terms and are on such other terms and conditions as set
forth in the Company’s respective forms of standard agreement. Pursuant to the employment agreement, Mr. Brunsberg was previously granted a stock option to purchase up to
100,000  shares  of  common  stock  of  the  Company,  at  an  exercise  price  equal  to  $3.18  per  share,  which  was  the  closing  market  price  of  the  Company’s  common  stock  on
September 20, 2021 (i.e., the date of grant), under the 2013 Equity Incentive Plan. Such option is fully vested and exercisable. The option has a five-year term and is on such
other terms set forth in the Company’s standard form of non-qualified stock option agreement, Further, Mr. Brunsberg is eligible to participate in the Company’s 2013 Equity
Incentive Plan and 2020 Stock Appreciation Rights Plan and is eligible to receive medical and dental benefits, life insurance, short and long-term disability coverage, and to

We  have  entered  into  an  “at  will”  employment  agreement,  effective  as  of  August  10,  2015,  with  Ronald  Fisher  under  which  he  was  engaged  to  serve  as  our  Vice
President of Business Development. Mr. Fisher is entitled to receive an annual base salary of $180,000. Pursuant to the employment agreement, Mr. Fisher also was granted, as
a signing bonus, (i) a stock option to purchase up to 2,375 shares of common stock of the Company, at an exercise price equal to $118.00 per share, which was the closing
market price of the Company’s common stock on August 10, 2015 (i.e., the date of grant), under the 2013 Equity Incentive Plan. Such option is fully vested and exercisable.
The option has a ten-year term and is on such other terms set forth in the Company’s standard form of non-qualified stock option agreement, and (ii) 125 shares of common
stock of the Company with a value equal to the closing price of our common stock on the date of grant and is on such other terms and provisions as are contained in Sigma
Labs’  standard  form  of  restricted  stock  letter  agreement  under  the  Plan.  Such  shares  are  fully  vested.  Additionally,  the  Company  granted  Mr.  Fisher  under  the  2013  Plan,
effective as of August 11, 2016, a stock option to purchase up to 500 shares of common stock of the Company. Such option has an exercise price equal to the closing price of
our common stock on the date of grant and is fully vested and exercisable. Further, Mr. Fisher is eligible to participate in the Company’s 2013 Equity Incentive Plan and Stock
Appreciation Rights Plan and is eligible to receive medical and dental benefits, life insurance, short and long-term disability coverage, and to participate in the Company’s

On September 18, 2017, we and Mr. Fisher entered into Amendment No. 1 to Mr. Fisher’s employment agreement, effective August 10, 2015, pursuant to which,
effective as of February 11, 2017, item 2, entitled “Performance Bonuses,” of Exhibit A of Mr. Fisher’s employment agreement was deleted in its entirety and replaced with the
new item 2 that was set forth in the amendment to employment agreement. Such amendment provided that Mr. Fisher would become entitled to receive performance-based
stock and cash bonuses if certain milestones were satisfied by February 11, 2018, so long as Mr. Fisher remained an employee of the Company as of the date the applicable
milestone was satisfied. On February 21, 2018, the Company and Mr. Fisher entered into Amendment No. 2 to Mr. Fisher’s employment agreement, pursuant to which the
foregoing February 11, 2018 date was extended to December 31, 2018. On January 10, 2019, the Company granted Mr. Fisher an option to purchase up to 1,184 shares of
common  stock  in  exchange  for  the  cancellation  of  his  accrued  but  unpaid  vacation  balance  at  December  31,  2018.  On  March  7,  2019,  the  Company  issued  150  shares  of
common stock under the 2013 Plan to Mr. Fisher connected with the satisfaction of a performance milestone.

On January 27, 2020, the Company entered into a Securities Purchase Agreement (the “SPA”) with Mark K. Ruport, Salvatore Battinelli and Frank Garofalo, a former
director,  and  Carl  Schwartz,  who  was  the  Company’s  largest  shareholder.  Pursuant  to  the  SPA,  the  Company  issued  and  sold  333.33  shares  of  the  Company’s  Series  E
Convertible  Preferred  Stock  (the  “Series  E  Preferred  Stock”),  and  5½  year  Class  A  Warrants  to  purchase  48,544  shares  of  the  Company’s  common  stock  (the  “Class  A
Warrants”)  for  a  total  gross  purchase  price  of  $500,000.  Upon  any  liquidation,  dissolution  or  winding-up  of  the  Company,  the  holders  of  Series  E  Preferred  Stock  will  be
entitled to receive out of the assets of the Company an amount equal to the stated value of the Series E Preferred Stock, plus any accrued and unpaid dividends thereon and any
other fees or liquidated damages then due and owing thereon under the Certificate of Designation, for each share of Series E Preferred Stock before any distribution or payment
may be made to the holders of any junior securities, but after distribution or payment to holders of the Series D Preferred Stock and any other senior securities; and if the assets
of the Company are insufficient to pay in full such amounts, then the entire assets to be distributed to the holders of Series E Preferred Stock are to be ratably distributed among
such holders in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full. The Series E Preferred Stock is
initially  convertible  into  48,544  shares  of  common  stock  (61,651  shares  of  common  stock  including  the  “make-whole  dividend),  and  the  Class  A  Warrants  have  an  initial
exercise price of $11.30 per share.

Indemnification Agreements

We have entered into indemnification agreements with each of our directors and executive officers. These agreements, among other things, require us to indemnify
each director and executive officer to the fullest extent permitted by Nevada law, including indemnification of expenses such as attorneys’ fees, judgments, fines and settlement
amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in the right of us, arising out of the person’s services
as a director or executive officer.

Policies and Procedures for Related Person Transactions

Our Audit Committee is responsible for reviewing and approving, as appropriate, all transactions with related persons (other than compensation-related matters, which
should be reviewed by our Compensation Committee), in accordance with its Charter and the Nasdaq marketplace rules. In reviewing and approving any such transactions, our
Audit Committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be
obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction.

In  the  above  table,  in  accordance  with  the  SEC’s  definitions  and  rules,  “audit  fees”  are  fees  that  we  paid  for  professional  services  for  the  audit  of  our  financial
statements included in our Form 10-K and review of the interim financial statements included in quarterly reports, and for services that are normally provided by the registered
public accounting firm in connection with statutory and regulatory filings or engagements; “audit-related fees” are fees for assurance and related services that are reasonably
related to the performance of the audit or review of our financial statements; and “tax fees” are fees for tax compliance, tax advice and tax planning.

The Audit Committee’s pre-approval policies and procedures and other protocols are discussed in its written charter which can be found at www.sigmalabsinc.com under the
tab “Investors.” Before our independent registered public accounting firm is engaged by the Company to render audit or non-audit services, the Audit Committee must pre-
approve  the  engagement.  Audit  Committee  pre-approval  of  audit  and  non-audit  services  are  not  required  if  the  engagement  for  the  services  is  entered  into  pursuant  to  pre-
approval policies and procedures established by the Audit Committee regarding the Company’s engagement of the independent registered public accounting firm, provided the
policies and procedures are detailed as to the particular service, the Audit Committee is informed of each service provided and such policies and procedures do not include
delegation of the Audit Committee’s responsibilities under the Exchange Act to the Company’s management. The Audit Committee may delegate to one or more designated
members  of  the Audit  Committee  the  authority  to  grant  pre-approvals.  If  the  Audit  Committee  elects  to  establish  pre-approval  policies  and  procedures  regarding  non-audit
services, the Audit Committee must be informed of each non-audit service provided by the independent registered public accounting firm. Audit Committee pre-approval of
non-audit  services  (other  than  review  and  attestation  services)  also  will  not  be  required  if  such  services  fall  within  available  exceptions  established  by  the  SEC.  The  Audit
Committee  may  not  engage  the  independent  registered  public  accounting  firm  to  perform  non-audit  services  prohibited  by  law  or  regulation.  On  an  annual  basis,  our
management reports to the Audit Committee all audit services performed during the previous 12 months and all fees billed by our independent registered public accounting firm
for such services.

Auditor Independence

In our fiscal year ended December 31, 2021, Haynie & Company provided no professional services other than those described above, that would require our Audit

Committee to consider their compatibility with maintaining the independence of Haynie & Company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Stockholders of Sigma Labs, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Sigma  Labs,  Inc.  (the  Company)  as  of  December  31,  2021  and  2020,  and  the  related  statements  of  operations,
stockholders’  equity,  and  cash  flows  for  each  of  the  years  in  the  two-year  period  ended  December  31,  2021,  and  the  related  notes  (collectively  referred  to  as  the  financial
statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the
results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2021, in conformity with accounting principles generally accepted in
the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our
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 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 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 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 financial statements. We
believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The  critical  audit  matters  communicated  below  are  matters  arising  from  the  current  period  audit  of  the  financial  statements  that  were  communicated  or  required  to  be
communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging,
subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are
not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenue Recognition – Multiple Deliverables in Revenue Contracts

Description of the Matter:

As  discussed  in  Note  1  to  the  financial  statements,  Sigma  Labs,  Inc.’s  revenue  is  derived  primarily  from  the  sale  of  software,  the  related  hardware  suite,  and
engineering services. The Company’s contracts with customers typically include the promise to transfer multiple goods and/or services to the customer. Management
must assess whether each promised good or service is distinct for the purpose of identifying the performance obligations within the contract and must then determine
and allocate the transaction price to the performance obligations. This assessment can be subjective and requires management to make judgments about the individual
promised goods or services and whether such goods or services are separable and distinct from the other aspects of the contractual relationship.

Auditing  management’s  assessment  and  recognition  of  revenue  can  be  complex,  involves  judgment,  and  is  based  on  a  thorough  understanding  of  the  Company’s
offerings.

How we Addressed the Matter in Our Audit:

We obtained a thorough understanding of the controls the Company has in place to perform this assessment including walk-throughs of the key controls and analysis of
the  design  and  operating  effectiveness  of  these  controls.  To  evaluate  Sigma  Labs  Inc.’s  assessment  of  performance  obligations  and  allocation  of  price,  our  audit
procedures included, among others, reading and evaluating management’s assumptions used to determine the distinct performance obligations and price allocations.
We compared the stand-alone price for each performance obligation to the allocated prices to ensure the allocation was reasonable. We also obtained confirmations
from customers verifying the terms of the contracts.

SIGMA LABS, INC.
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2021

NOTE 1 – Summary of Significant Accounting Policies

Nature of Business –Sigma Labs, Inc., formerly named Framewaves, Inc., a Nevada corporation, was founded by a group of scientists, engineers and businessmen to develop
and  commercialize  novel  and  unique  manufacturing  and  materials  technologies.  Sigma  believes  that  some  of  these  technologies  will  fundamentally  redefine  conventional
quality assurance and process control practices by embedding them into the manufacturing processes in real time, enabling process intervention and ultimately leading to closed
loop  process  control.  The  Company  anticipates  that  its  core  technologies  will  allow  its  clientele  to  combine  advanced  manufacturing  quality  assurance  and  process  control
protocols with novel materials to achieve breakthrough product potential in many industries including aerospace, defense, oil and gas, bio-medical, and power generation. The
terms the “Company,” “Sigma,” “we,” “us” and “our” refer to Sigma Labs, Inc.

Reverse Stock Split - Effective February 27, 2020, our Articles of Incorporation were amended to provide for a reverse stock split of the outstanding shares of our common
stock on a 1-for-10 basis (the “Reverse Stock Split”), and a corresponding decrease in the number of shares of our common stock that we are authorized to issue (the “Share
Decrease”). The effects of the stock split have been retroactively reflected to all periods presented.

Basis of Presentation – The accompanying financial statements have been prepared by the Company in accordance with Generally Accepted Accounting Principles (“GAAP”)
in the United States of America. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial
position, results of operations and cash flows at December 31, 2021 and 2020 and for the periods then ended have been made.

Reclassification  -  Certain  amounts  in  prior-period  financial  statements  have  been  reclassified  for  comparative  purposes  to  conform  to  presentation  in  the  current-period
financial statements. These reclassifications have no impact on the previously reported results

Continuing Operations – The Company has sustained losses and had negative cash flows from operating activities since its inception. Commencing in 2017, the company
committed itself to a focused initiative to transition its product and its company culture from research and development into an enterprise with a commercial industrial product
and a business-oriented operation culture.

In 2021 and 2020, the Company relied on both public and private offerings to finance its operations. In January 2021, the Company closed a public offering of our common
stock in which it issued 1,711,783 shares of common stock at $3.00 per share, resulting in net proceeds of approximately $4,532,444 after deducting underwriting discounts and
commissions and other offering expenses payable by the Company. In March 2021, the Company closed a public offering of its securities in which it issued 2,190,000 shares of
common stock at $4.445 per share, resulting in net proceeds to the Company of approximately $8,736,488 after deducting placement agent commissions and other offering
costs payable by the Company. During the first quarter of 2021, the Company issued 454,404 shares of common stock pursuant to the exercise of warrants, resulting in net
proceeds to the Company of $1,136,010.

In January 2020, we completed two private placements consisting of shares of our newly created Series D and Series E Preferred Stock, warrants to purchase additional
shares of Series D Preferred Stock and warrants to purchase shares of our Common Stock resulting in net cash proceeds to us of approximately $1,711,124. On March 27, 2020,
pursuant to the terms of the Agreement, we forced the exercise of a portion of the warrants to purchase our Series D Preferred Stock which resulted in net cash proceeds to the
Company  of  $460,000.  On  April  6,  2020,  the  Company  closed  an  offering  of  equity  securities  in  which  the  Company  sold  and  issued  to  certain  institutional  investors  (a)
493,027  shares  of  the  Company’s  common  stock  (the  “Common  Shares”)  and  pre-funded  warrants  (the  “Pre-funded  Warrants”)  to  purchase  up  to  22,438  shares  of  the
Company’s  common  stock,  and  (b)  Series A  Warrants  (the  “Private  Warrants”)  to  purchase  an  aggregate  of  515,465 shares  of  the  Company’s  common  stock  pursuant  to  a
private placement resulting in net proceeds of approximately $1,230,000. On April 14, 2020 we were granted a loan from BOKF, NA dba Bank of Oklahoma in the aggregate
amount  of  $361,700,  pursuant  to  the  Paycheck  Protection  Program  (the  “PPP”)  under  Division  A,  Title  I  of  the  Coronavirus  Aid,  Relief  and  Economic  Security Act  (the
“CARES Act”), which was enacted March 27, 2020. The Company used the entire loan proceeds to fund payroll expenses, and as such, the loan was forgiven in full on January
13, 2021.

F-7

 
 
 
 
 
 
 
 
 
 
 
The continuing operations of the Company are no longer solely dependent upon financing the cost of product development in the absence of revenues, but rather upon our
abilities to finance our efforts to successfully ramp up commercialization, thus earning the product validation of both customer licensing and purchases and creating a dynamic
in which public and private offerings facilitate the growth of revenues.

As a result, the Company currently has sufficient cash and working capital to fund operations through the end of 2022 and is anticipating that contracts may be closed during
fiscal 2022 generating additional cash flow in the near-term. In addition, the Company has access to public and private markets from which to derive additional financing to
sustain  operations  beyond  that  term,  if  required;  however,  the  Company  is  unable  to  predict  the  extent  to  which  the  novel  coronavirus  or  global  economic  and  geopolitical
developments may affect the financial markets and the Company’s access to such markets. There is no assurance that we will be successful in obtaining additional funding. If
we fail to obtain sufficient funding when needed, we may be forced to delay, scale back or eliminate all or a portion of our commercialization efforts and operations.

Loss Per Share – The computation of loss per share is based on the weighted average number of shares outstanding during the period in accordance with ASC Topic No. 260,
“Earnings Per Share.” Shares underlying the Company’s outstanding warrants, options or note conversion features were excluded due to the anti-dilutive effect they would have
on the computation. At December 31, 2021 and 2020, the Company had the following common shares underlying these instruments:

Warrants
Preferred Stock Warrants
Stock Options
Preferred Stock

Property and Equipment – Property and equipment are stated at cost. Expenditures for major renewals and betterments that extend the useful lives of property and equipment
are capitalized upon being placed in service. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line
method  over  the  estimated  useful  lives  of  the  assets.  The  estimated  life  has  been  determined  to  be  five  years  unless  a  unique  circumstance  exists,  which  is  then  fully
documented as an exception to the policy.

In accordance with its policy, the Company reviews the estimated useful lives of its fixed assets on an ongoing basis.

Income Taxes – The Company accounts for income taxes in accordance with ASC Topic No. 740, “Accounting for Income Taxes.”

The Company has no tax positions at December 31, 2021 and 2020 for which the ultimate deductibility is highly uncertain but for which there is uncertainty about the timing of
such deductibility.

The Company recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses. During the years ended December 31,
2021 and 2020, the Company recognized no interest and penalties. All tax years starting with 2018 are open for examination.

Accounts Receivable and Allowance for Doubtful Accounts - Trade accounts receivable are carried at original invoice amount less an estimate made for doubtful accounts.
We determine the allowance for doubtful accounts by identifying potential troubled accounts and by using historical experience and future expectations applied to an aging of
accounts. Trade accounts receivable are written off when deemed uncollectible. Recoveries of trade accounts receivable previously written off are recorded as income when
received. There was no allowance for doubtful accounts at December 31, 2021 or 2020.

Long-Lived and Intangible Assets  –  Long-lived  assets  and  certain  identifiable  definite  life  intangibles  to  be  held  and  used  by  the  Company  are  reviewed  for  impairment
whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company continuously evaluates the recoverability of
its long-lived assets based on estimated future cash flows and the estimated liquidation value of such long-lived assets and provides for impairment if such undiscounted cash
flows are insufficient to recover the carrying amount of the long-lived assets. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is
recorded as the difference between the carrying value and fair value. Fair values are determined based on quoted market values, discounted cash flows or internal and external
appraisals, as applicable. Assets to be disposed of are carried at the lower of carrying value or estimated net realizable value. Three patents were written off totaling $10,510 in
December of 2021, and no patents were written off in 2020.

Cash Equivalents - The Company considers all highly liquid investments with an original maturity of three months or less at date of purchase to be cash equivalents.

Fair Value  of  Financial  Instruments  -  The  Company  applies  ASC  820,  “Fair  Value  Measurements.”  This  guidance  defines  fair  value,  establishes  a  three-level  valuation
hierarchy for disclosures of fair value measurement and enhances disclosure requirements for fair value measures. The three levels are defined as follows:

● Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

● Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or

liability, either directly or indirectly, for substantially the full term of the financial instrument.

● Level 3 - inputs to valuation methodology are unobservable and significant to the fair measurement.

The  carrying  amounts  reported  in  the  balance  sheets  for  the  cash  and  cash  equivalents,  receivables,  accounts  payable,  and  accrued  liabilities  each  qualify  as  financial
instruments and are a reasonable estimate of fair value because of the short period of time between the origination of such instruments and their expected realization and their
current market rate of interest.

The Company does not use derivative instruments for hedging of market risk or for trading or speculative purposes. On March 26, 2021, the Company closed an offering in
which  it  issued  warrants  to  purchase  an  aggregate  of  2,190,000  shares  of  common  stock  in  a  private  placement  concurrently  with  a  registered  direct  offering  (“Registered
Offering”) of our common stock The warrants became exercisable on May 24, 2021, the date the Company obtained stockholder approval to increase its authorized common
shares from 12,000,000 to 24,000,000 (“the Initial Exercise Date”) and will expire two years after the Initial Exercise Date.

Pursuant to ASC 815-40-25-10, because the Company did not have sufficient authorized and unissued shares of common stock available to settle the warrants at the issue date,
such  warrants  were  accounted  for  as  a  derivative  liability.  On  May  24,  2021,  upon  receiving  shareholder  approval  to  increase  its  authorized  common  shares,  the  Company
reclassified the warrant liability to equity pursuant to ASC 815.40.35.8.

The fair value of the warrant liability measured on a recurring basis is as follows:

Concentration  of  Credit  Risk -  The  Company  maintains  its  cash  in  bank  deposit  accounts,  which,  at  times,  may  exceed  federally  insured  limits.  The  Company  has  not
experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash and cash equivalents.

Stock Based Compensation – The Company recognizes compensation costs to employees under ASC Topic No. 718, “Compensation – Stock Compensation.” Under ASC
Topic No. 718, companies are required to measure the compensation costs of share-based compensation arrangements based on the grant-date fair value and recognize the costs
in the financial statements over the period during which employees are required to provide services. Share based compensation arrangements may include stock options, grants
of shares of common stock with and without restrictions, performance-based awards, share appreciation rights and employee share purchase plans. As such, compensation cost
is measured on the date of grant at its fair value. Such compensation amounts, if any, are amortized over the respective vesting periods of the option or stock grants.

Equity instruments issued to non-employees are recorded on the basis of the fair value of the instruments, as required by ASC Topic No. 505, “Equity Based Payments to Non-
Employees.” In general, the measurement date is either (a) when a performance commitment, as defined, is reached or (b) the earlier of the date that (i) the non-employee
performance  requirement  is  complete  or  (ii)  the  instruments  are  vested.  The  measured  value  related  to  the  instruments  is  recognized  over  a  period  based  on  the  facts  and
circumstances of each particular grant as defined in the FASB Accounting Standards Codification.

Amortization - Utility patents are amortized over a 17-year period. Patents which are pending are not amortized.

Accounting Estimates - The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make
estimates and assumptions that affect certain reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the financial statements,
and  the  reported  amounts  of  revenues  and  expenses  during  the  reporting  period.  Actual  results  could  differ  from  those  estimated  by  management.  Significant  accounting
estimates that may materially change in the near future are impairment of long-lived assets, values of stock compensation awards and stock equivalents granted as offering
costs, and allowance for bad debts and inventory obsolescence.

Revenue Recognition – The Company’s revenue is derived primarily from sales of our software and related hardware suite and from providing engineering services under
contracts.  The  Company  recognizes  revenue  in  accordance  with  ASC  Topic  No.  606.  In  May  2014,  the  Financial  Accounting  Standards  Board  (FASB)  issued  Accounting
Standards  Update  (ASU)  No.  2014-09,  Revenue  from  Contracts  with  Customers. ASU  2014-09  is  a  comprehensive  revenue  recognition  standard  that  superseded  nearly  all
existing revenue recognition guidance under prior U.S. GAAP and replace it with a principles-based approach for determining revenue recognition. The core principle of the
standard is the recognition of revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to
be entitled in exchange for those goods or services.

In general, we determine revenue recognition by: (1) identifying the contract, or contracts, with our customer; (2) identifying the performance obligations in the contract; (3)
determining  the  transaction  price;  (4)  allocating  the  transaction  price  to  performance  obligations  in  the  contract;  and  (5)  recognizing  revenue  when,  or  as,  we  satisfy
performance obligations by transferring the promised goods or services.

Deferred Stock Offering Costs – Costs related to stock offerings (if any) are deferred and will be offset against the proceeds of the offering in additional paid-in capital. In the
event a stock offering is unsuccessful, the costs relating to the offering will be written-off directly to expense.

Inventory – Inventories consist of raw materials used in the production of customized parts, work-in-process and finished goods components which will be sold to customers.
Inventories are valued at the lower of cost or net realizable value, using the first-in, first-out (FIFO) method.

Research and Development – Research and development costs are expensed as they are incurred. Research and development costs for the years ended December 31, 2021 and
2020 were $417,744 and $126,292, respectively.

NOTE 4 – Intangible Assets

The Company’s intangible assets consist of Patents and Patent Pending Applications.

Provisional patent applications are not amortized until a patent has been granted. Once a patent is granted, the Company will amortize the related costs over the estimated useful
life of the patent. If a patent application is denied, then the costs will be expensed at that time.

During 2021, $91,260 of costs related to patents issued to us during 2021 were reclassified from provisional patent application to patent status and began to be amortized as of
the date of issue.

NOTE 5 – Paycheck Protection Plan Loan

On April  14,  2020,  the  Company  was  granted  a  loan  from  BOKF,  NA  dba  Bank  of  Oklahoma  in  the  aggregate  amount  of  $361,700,  pursuant  to  the  Paycheck  Protection
Program (the “PPP”) under Division A, Title I of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), which was enacted March 27, 2020. Under the
terms of the PPP, PPP loans and accrued interest are forgivable after twenty-four weeks as long as the borrower uses the loan proceeds for eligible purposes, including payroll,
benefits, rent and utilities, and maintains its payroll levels. The amount of loan forgiveness will be reduced if the borrower terminates employees or reduces salaries during the
forgiveness period.

As of December 31, 2020, the Company had used the entire loan proceeds to fund its payroll expenses. As a result, the Company concluded that it met the PPP eligibility
criteria for forgiveness and recognized the entire loan amount as Other Income.

In January 2021, the Company received notice from the lender that the entire amount of the loan had been forgiven.

NOTE 6 – Deferral of Social Security Tax Payments

Pursuant to sections 2302(a)(1) and (a)(2) of the CARES Act, the Company has elected to defer payments of its share of Social Security tax due during the “payroll tax deferral
period”. The payroll tax deferral period began on March 27, 2020 and ended on December 31, 2020. At December 31, 2021 the total remaining amount of the deferral was
$37,728. Per the terms of the deferral program, such amount is due on December 31, 2022 at 0% interest.

NOTE 7 - Derivative Liability

On  March  26,  2021  (the  “Issuance  Date”),  the  Company  issued  warrants  to  purchase  an  aggregate  of  2,190,000  shares  of  common  stock  to  holders  in  a  private  placement
concurrently  with  a  registered  direct  offering  of  2,190,000  shares  of  its  common  stock.  The  warrants  entitle  the  holders  to  purchase  one  share  of  our  common  stock  at  an
exercise price equal to $4.32 per share commencing on May 24, 2021 and will expire two years from such date. The Company has determined that these warrants are free
standing  financial  instruments  that  are  legally  detachable  and  separately  exercisable  from  the  common  stock  included  in  the  registered  direct  offering.  Management  also
determined that on the Issuance Date, the Company did not have sufficient authorized and unissued shares to settle the warrants, and as such required classification as a liability
pursuant to ASC 815 “Derivative Instruments and Hedging”. In accordance with the accounting guidance, the outstanding warrants were recognized as a warrant liability on
the balance sheet and were measured at their inception date fair value and subsequently re-measured at each reporting period with changes being recorded as a component of
other income in the statement of operations.

At a Special Stockholders Meeting held on May 24, 2021, the Company received approval to increase its authorized common shares from 12,000,000 to 24,000,000. Pursuant
to ASC 815-40-35-8, the Company reclassified the warrant liability to equity as of such date.

The fair value of the derivative liability presented below was measured using the Black Scholes valuation model. Significant inputs into the model for the year ended December
31, 2021 are as follows:

Dividend yield
Risk-free interest rate
Expected volatility
Expected life (in years)

The  Company  has  presented  the  fair  value  measurement  as  a  Level  3  measurement,  relying  on  unobservable  inputs  reflecting  management’s  assumptions.  Level  3
measurements, which are not based on quoted prices in active markets, introduce a higher degree of subjectivity and may be more sensitive to fluctuations in stock prices,
volatility rates and U.S. Treasury Bond rates and could have a material impact on future fair value measurements.

The Company uses the Black Scholes model, based on the adjusted historical volatility rates for fair value measurements through the date of stockholder approval (i.e., May 24,
2021). Management has determined the Black Scholes model to be the most reliable and least volatile determinate of the current fair value of the warrants. It is the Company’s
expectation to maximize on all observable market inputs for the warrants and calibrate the model to incorporate relevant observable market data into the fair value measurement
at each future measurement date, if applicable.

During the twelve months ended December 31, 2021, the Company recognized a gain of $1,092,441 on the change in fair value of the warrants.

NOTE 8 – Stockholders’ Equity

Common Stock

Effective February 27, 2020, our Articles of Incorporation were amended to provide for a reverse stock split of the outstanding shares of our common stock on a 1-for-10 basis
(the “Reverse Stock Split”), and a corresponding decrease in the number of shares of our common stock that we are authorized to issue (the “Share Decrease”). The effects of
the stock split have been retroactively reflected to all periods presented.

On  May  24,  2021,  at  a  special  shareholders’  meeting,  our  authorized  shares  of  common  stock  were  increased  from  12,000,000  to  24,000,000. At  our  annual  shareholders’
meeting held on June 15, 2020, our authorized shares of common stock were increased from 8,000,000 to 12,000,000. On March 27, 2020, at a special shareholders’ meeting,
our authorized shares of common stock were increased from 2,250,000 to 8,000,000.

In January 2021, the Company closed a public offering of its securities in which it issued 1,711,783 shares of common stock at $3.00 per share, resulting in net proceeds of

Company also issued to the Underwriter or its designee warrants to purchase 136,943 shares of common stock. Such warrants have a term of five years and an exercise price of
$3.75 per share.

In February 2021, the Company issued 263,200 shares of common stock pursuant to the exercise of warrants issued in our January 2020 private placement.

In March 2021, the Company issued 119,000 shares of common stock in exchange for the conversion of 250 shares of Series D Convertible Preferred Stock, including 19,000
shares of common stock as in-kind payment of preferred stock dividends. Also in March 2021, the Company issued 191,204 shares of common stock pursuant to the exercise of

In March 2021, the Company closed a public offering of its securities in which it issued 2,190,000 shares of common stock at $4.445 per share, resulting in net proceeds to the
Company of approximately $8,736,488 after deducting placement agent commissions and other offering costs payable by the Company. In a concurrent private placement under
the Purchase Agreement, the Company issued to the purchasers warrants to purchase an aggregate of 2,190,000 shares of Common Stock at an exercise price of $4.32 per share.
Each Warrant became exercisable on May 24, 2021, the date the Company obtained stockholder approval of an increase in the authorized shares of the Company’s Common
Stock and will expire two years from such date. The Company also issued to designees of the Placement Agent warrants to purchase up to 175,200 shares of Common Stock
(the “Placement Agent Warrants”) constituting 8% of the aggregate number of shares of Common Stock sold in the Registered Offering. The Placement Agent Warrants have
substantially the same terms as the Warrants, except that the Placement Agent Warrants have an exercise price equal to 125% of the offering price per share (or $5.55625 per
share). Upon any exercise of the Warrants for cash, we have also agreed to pay the Placement Agent warrants to purchase 8.0% of the number of shares of our Common Stock
issued upon the cash exercise of the Warrants.

In March 2021, Company issued 1,500 shares of common stock valued at $4.99 per share to an investor relations firm as partial compensation for services previously rendered.

In September 2021, the Company granted 5,204 shares of common stock to non-executive employees pursuant to the 2013 Equity Incentive Plan.

pursuant to a private placement. In connection with this offering, the Company issued Dawson James Securities, Inc., its Placement Agent, a warrant to purchase an aggregate
of 41,237 shares of the Company’s Common Stock (which amount is based on the number of Common Shares and shares underlying the Pre-Funded Warrants) at an exercise
price of $3.64 per share. Net proceeds to the Company after deducting offering expenses were approximately $1,230,000. On December 4, 2020, the Company issued 22,438
shares of common stock for the exercise of the pre-funded warrants.

In the twelve months ended December 31, 2020, the Company issued 3,272,048 shares of common stock in exchange for the conversion of 7,404 shares of Series D Convertible

Deferred Compensation

In 2021 and 2020, the Company issued to various employees, directors, and contractors shares of the Company’s common stock, subject to restrictions, pursuant to the 2013
Equity Incentive Plan (the “2013 Plan”). Such shares were valued at the fair value at the date of issue. The fair value was expensed as compensation over the vesting period and
recorded  as  a  reduction  of  stockholders’  equity.  During  2021  and  2020,  $19,255  and  $77,187,  respectively,  of  the  unvested  compensation  cost  related  to  these  issues  was
recognized.

Preferred Stock

The Company is authorized to issue 10,000,000 shares of preferred stock, $0.001 par value. 465 and 715 shares of preferred stock were issued and outstanding at December 31,
2021 and 2020, respectively.

In January 2020, the Company entered into a Securities Purchase Agreement (the “SPA”) with certain institutional investors (the “Institutional Private Placement”). Pursuant to
the  SPA,  the  Company  issued  and  sold  1,640  shares  of  the  Company’s  newly  created  Series  D  Convertible  Preferred  Stock  (the  “Series  D  Preferred  Stock”).  Under  the
Certificate of Designations for the Series D Preferred Stock, the Series D Preferred Stock has an initial stated value of $1,000 per share (the “Stated Value”). Dividends accrue
at a dividend rate of 9% per annum (subject to increase upon the occurrence (and during the continuance) of certain triggering events described therein) and, on a monthly
basis, shall be payable in kind by the increase of the Stated Value of the Series D Preferred Shares by said amount. The holders of the Series D Preferred Shares will have the
right at any time to convert all or a portion of the Series D Preferred Shares (including, without limitation, accrued and unpaid dividends and make-whole dividends through the
third anniversary of the closing date) into shares of the Company’s Common Stock at the conversion price then in effect, which is $2.50 (subject to adjustment for stock splits,
dividends, recapitalizations and similar events and full ratchet price protection). In addition, a holder may at any time, alternatively, convert all, or any part, of its Series D
Preferred Shares at an alternative conversion price, which equals the lower of the applicable conversion price then in effect, and the greater of (x) $1.80 and (y) 85% of the
average volume weighted average price (“VWAP”) of the Common Stock for a five (5) trading day period prior to such conversion. Upon the occurrence of certain triggering
events, described in the Certificate of Designations, including, but not limited to payment defaults, breaches of transaction documents, failure to maintain listing on the Nasdaq
Capital Market, and other defaults set forth therein, the Series D Preferred Shares would become subject to redemption, at the option of a holder, at a 125% premium to the
underlying value of the Series D Preferred Shares being redeemed.

At December 31, 2021 there were 132 shares of Series D Convertible Preferred stock outstanding, which if converted as of December 31, 2021, including the make-whole
dividends, would have resulted in the issuance of 87,267 shares of common stock.

Concurrent with the Institutional Private Placement, the Company entered into a Securities Purchase Agreement (the “SPA”) with certain of its directors and the Company’s
formerly  largest  shareholder  (the  “Other  Private  Placement”).  Pursuant  to  the  SPA,  the  Company  issued  and  sold  333  shares  of  the  Company’s  newly  created  Series  E
Convertible Preferred Stock (the “Series E Preferred Stock”). Dividends accrue at a dividend rate of 9% per annum and, on a monthly basis, shall be payable in kind by the
increase of the Stated Value of the Series E Preferred Shares by said amount. The Series E Preferred Stock is initially convertible into 48,544 shares of Common Stock.

At  December  31,  2021,  all  of  the  issued  Series  E  Convertible  Preferred  Stock  were  outstanding,  which  if  converted  as  of  December  31,  2021,  including  the  make-whole
dividends, would have resulted in the issuance of 61,651 shares of common stock.

Stock Options

On July 15, 2021, at the Annual Meeting of Stockholders of the Company, the Company’s stockholders approved an amendment to the 2013 Plan to increase the number of
shares of the Company’s common stock reserved for issuance under the 2013 Plan by 875,000 shares of our common stock to a total of 1,765,000 shares. As of December 31,
2021, there were 339,677 shares available for issuance under the 2013 Plan.

During 2021, the Company granted a total of 698,831 options to 35 employees, 4 directors, and 4 consultants with vesting periods ranging from immediately upon issue to three
years beginning January 4, 2021. In 2021, 598,789 options vested and $1,741,366 of compensation cost was recognized during the year. As of December 31, 2021, there were
options to purchase 1,395,882,  shares  issued  and  outstanding,  1,345,882  of  which  have  been  issued  under  the  2013  Plan.  At  December  31,  2021,  there  are  vested  options
exercisable for 941,934 shares of common stock. Options to purchase 5,204 shares of common stock were exercised during the year ended December 31, 2021.

During 2020, the Company granted a total of 579,998 options to 19 employees, 4 directors, and 5 consultants with vesting periods ranging from immediately upon issue to three
years  beginning  May  1,  2020. In 2020, 294,373  options  vested  and  $854,217  of  compensation  cost  was  recognized  during  the  year.  As  of  December  31,  2020,  there  were
options  to  purchase  713,010  shares  issued  and  outstanding,  663,010  of  which  have  been  issued  under  the  2013  Plan.  At  December  31,  2020,  there  were  vested  options
exercisable for 349,642 shares of common stock. No options were exercised during the year ended December 31, 2020.

The Company generally grants stock options to employees, consultants and directors at exercise prices equal to the fair market value of the Company’s stock on the dates of
grant. Stock options are typically granted throughout the year and generally vest over three years of service and expire five years from the date of the award, unless otherwise
specified. The Company recognizes compensation expense for the fair value of the stock options over the requisite service period for each stock option award.

Total employee share-based compensation expense included in the statements of operations for the year ended December 31, 2021 is $1,066,455 of which $1,047,200 is related
to stock options. Total employee share-based compensation for 2020 totaled $596,842, of which $573,232 is related to stock options. There was no capitalized share-based
compensation cost as of December 31, 2021 and 2020, and there were no recognized tax benefits during the years ended December 31, 2021 and 2020.

To estimate the value of an award, the Company uses the Black-Scholes option-pricing model. This model requires inputs such as expected life, expected volatility and risk-free
interest rate. The forfeiture rate also impacts the amount of aggregate compensation. These inputs are subjective and generally require significant analysis and judgment to
develop. While estimates of expected life, volatility and forfeiture rate are derived primarily from the Company’s historical data, the risk-free rate is based on the yield available
on U.S. Treasury constant maturity rates with similar terms to the expected term of the stock option awards. The fair value of share-based awards was estimated using the
Black-Scholes model with the following weighted-average assumptions for the years ended December 31, 2021 and 2020:

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of our common stock for those awards that
have an exercise price currently below the $1.84 closing price of our Common Stock on December 31, 2021. All of the 2021 option grants have an exercise price currently
above $1.84.

At  December  31,  2021,  there  was  $1,164,723  of  unrecognized  share-based  compensation  expense  related  to  unvested  share  options  with  a  weighted  average  remaining
recognition period of 2.10 years.

Stock Appreciation Rights

On June 23, 2020, the board of directors (the “Board”) of the Company adopted the Sigma Labs, Inc. 2020 Stock Appreciation Rights Plan (the “Plan”). The purposes of the
Plan  are  to:  (i)  enable  the  Company  to  attract  and  retain  the  types  of  employees,  consultants,  and  directors  (collectively,  “Service  Providers”)  who  will  contribute  to  the
Company’s long-range success; (ii) provide incentives that align the interests of Service Providers with those of the shareholders of the Company; and (iii) promote the success
of the Company’s business. The Plan provides for incentive awards that are only made in the form of stock appreciation rights payable in cash (“SARs”). No shares of common
stock were reserved in connection with the adoption of the Plan since no shares will be issued pursuant to the Plan.

SARs may be granted to any Service Provider. A SAR is the right to receive an amount equal to the Spread with respect to a share of the Company’s common stock (“Share”)
upon the exercise of the SAR. The “Spread” is the difference between the exercise price per share specified in a SAR agreement on the date of grant and the fair market value
per share on the date of exercise of the SAR. The exercise price per share will not be less than 100% of the fair market value of a Share on the date of grant of the SAR. The
administrator of the Plan will have the authority to, among other things, prescribe the terms and conditions of each SAR, including, without limitation, the exercise price and
medium of payment and vesting provisions, and to specify the provisions of the SAR Agreement relating to such grant.

On  August  11,  2021,  the  Company  granted,  pursuant  to  the  Plan,  (i)  77,748  SARs  to  its  Chief  Executive  Officer,  (ii)  30,313  SARs  to  its  Vice  President  of  Business
Development, (iii) 76,304 SARs to its Chief Technology Officer, and (iv) 48,580 SARs to its Chief Financial Officer. The exercise price of each such SAR is $3.42, which was
the closing price of the Company’s common stock on the date of grant. On June 23, 2020, the Company granted, pursuant to the Plan, (i) 60,094 SARs to its Chief Executive
Officer, (ii) 12,019 SARs to its Vice President of Business Development, (iii) 24,038 SARs to its Chief Technology Officer, and (iv) 18,028 SARs to its Chief Financial Officer.
The exercise price of each such SAR is $2.63, which was the closing price of the Company’s common stock on the date of grant. Such SARs expire on the fifth anniversary of
the grant date and may be settled only in cash. Additionally, each such SAR will vest and become exercisable in three equal (as closely as possible) installments on each of the
first, second and third anniversaries of the grant date, subject, in each case, to the applicable SAR holder being in the continuous employ of the Company on the applicable
vesting  date,  and,  in  the  event  of  a  Change  in  Control  (as  defined  in  the  Plan),  will  become  immediately  vested  and  exercisable  as  long  as  the  applicable  holder  is  in  the
Company’s employ immediately prior to the Change in Control, and will otherwise be on such other terms set forth in the form of Stock Appreciation Rights Agreement.

On July 29, 2021, we granted 10,000 SARs to a consultant as partial compensation for services pursuant to his consulting agreement, and on November 19, 2020, we granted
13,500  SARs  to  such  consultant  as  partial  compensation  for  services  pursuant  to  his  consulting  agreement. As  of  December  31,  2021,  all  such  SARs  were  full  vested  and
exercisable.

The Company recognizes compensation expense and a corresponding liability for the fair value of the SARs over the requisite service period for each SAR award. The SAR’s
are  revalued  at  each  reporting  date  in  accordance  with  ASC  718  “Compensation-Stock  Compensation”,  and  any  changes  in  fair  value  are  reflected  in  income  as  of  the
applicable reporting date.

The  fair  value  of  SAR  awards  was  estimated  using  the  Black-Scholes  model  with  the  following  weighted-average  assumptions  for  the  twelve  months  ended  December  31,

NOTE 9 – Income Taxes

The Company accounts for income taxes in accordance with ASC Topic No. 740. This standard requires the Company to provide a net deferred tax asset or liability equal to the
expected  future  tax  benefit  or  expense  of  temporary  reporting  differences  between  book  and  tax  accounting  methods  and  any  available  operating  loss  or  tax  credit
carryforwards. Income tax returns open for examination by the Internal Revenue Service consist of tax years ended December 31, 2018 through 2020.

The Company has available at December 31, 2021, unused operating loss carryforwards of approximately $26,342,855 which may be applied against future taxable income and
which expire  in  various  years  through  2040.  However,  if  certain  substantial  changes  in  the  Company’s  ownership  should  occur,  there  could  be  an  annual  limitation  on  the
amount of net operating loss carryforward which can be utilized. The amount of and ultimate realization of the benefits from the operating loss carryforwards for income tax
purposes is dependent, in part, upon the tax laws in effect, the future earnings of the Company and other future events, the effects of which cannot be determined. Because of
the uncertainty surrounding the realization of the loss carryforwards, the Company has established a valuation allowance equal to the tax effect of the loss carryforwards and
other  temporary  differences  of  approximately  $6,771,000  and  $4,170,100  at  December  31,  2021  and  2020,  respectively,  and,  therefore,  no  deferred  tax  asset  has  been
recognized for the loss carryforwards.

Deferred tax assets are comprised of the following:

Deferred tax assets:
NOL carryover
Depreciation
Valuation allowance

3,987,931  shares  of  common  stock,  and  1,395,882  stock  options  exercisable  for  1,395,882  shares  of  common  stock,  132  shares  of  Series  D  Preferred  Stock,  which  is
convertible into 87,267 shares of common stock, and 333 shares of Series E Preferred Stock, which could be converted into 61,651 shares of common stock, resulting in a
potential total additional 5,532,731 shares of common stock outstanding in the future. At December 31, 2020, the Company had outstanding 1,881,429 common warrants which
could  be  converted  to  1,881,429  shares  of  common  stock,  and  713,010  stock  options  exercisable  for  713,010  shares  of  common  stock,  10  Series  D  Preferred  Warrants
exercisable for 10 shares of Series D Preferred Stock, which in turn, are convertible into 4,748 shares of common stock, and 715 shares of preferred stock, which could be
converted into 243,024 shares of common stock, resulting in a potential total additional 2,842,211 common stock shares outstanding in the future.

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT
TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.15

Sigma Labs, Inc. (“Sigma,” “we,” “our,” and “us”) has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, which

is our common stock, par value $0.001 per share (the “common stock”).

The following description of our common stock, and preferred stock is a summary and does not purport to be complete. It is subject to and qualified in its entirety by
reference to (1) our Amended and Restated Articles of Incorporation filed as an Exhibit to our Form 10-K, (2) our Certificate of Correction to Amended and Restated Articles
of Incorporation filed as an Exhibit to our Current Report on Form 8-K on June 1, 2011, (3) our Amended and Restated Bylaws filed as an Exhibit to our Form 10-K, (4)
Certificate  of  Designations  of  Rights  Preferences  and  Privileges  of  our  Series  D  Convertible  Preferred  Stock  filed  as  an  Exhibit  to  our  Current  Report  on  Form  8-K  filed
January 30, 2020, and (5) Certificate of Designations of Rights Preferences and Privileges of our Series E Convertible Preferred Stock filed as an Exhibit to our Current Report
on Form 8-K on January 30, 2020, each of which is filed as an exhibit to our Annual Report on Form 10-K of which this Exhibit 4.15 is a part. We encourage you to read the
Articles of Incorporation, the Bylaws, and the Certificates of Designations, as well as the applicable provisions of the Nevada Revised Statutes (the “NRS”), for additional
information.

Authorized Capital Stock

We are presently authorized to issue 24,000,000 shares of common stock, $0.001 par value per share, of which 10,498,802 shares were outstanding as of March 23,
2022. We are presently authorized to issue 10,000,000 shares of $0.001 par value preferred stock, of which 1,610,000 shares have been designated “Series A Preferred Stock,”
1,000 shares have been designated “Series B Convertible Preferred Stock,” 1,500 shares have been designated “Series C Convertible Preferred Stock,” 7,796 shares have been
designated as “Series D Convertible Stock” and 500 shares have been designated as “Series E Convertible Stock.” As of the date of this Form 10-K, we had no shares of Series
A Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible Stock issued and outstanding, 132 shares of Series D Convertible Preferred Stock issued and
outstanding and 333.33 shares of Series E Convertible Preferred Stock issued and outstanding.

Common Stock

We have one class of common stock. Holders of our common stock are entitled to one vote per share on all matters to be voted upon by stockholders and do not have
cumulative voting rights in the election of directors. Holders of shares of common stock are entitled to receive on a pro rata basis such dividends, if any, as may be declared
from time to time by our board of directors in its discretion from funds legally available for that use, subject to any preferential dividend rights of outstanding preferred stock.
They are also entitled to share on a pro rata basis in any distribution to our common stockholders upon our liquidation, dissolution or winding up, subject to the prior rights of
any outstanding preferred stock. Common stockholders do not have preemptive rights to subscribe to any additional stock issuances by us, and they do not have the right to
require the redemption of their shares or the conversion of their shares into any other class of our stock. The rights, preferences and privileges of holders of common stock are
subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Under our articles of incorporation, our board of directors has the authority, without further action by stockholders, to designate one or more series of preferred stock
and to fix the voting powers, designations, preferences, limitations, restrictions and relative rights granted to or imposed upon the preferred stock, including dividend rights,
conversion rights, voting rights, rights and terms of redemption, liquidation preference and sinking fund terms, any or all of which may be preferential to or greater than the
rights of the common stock.

 
 
 
 
 
 
 
 
 
 
 
 
Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the
holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among
other things, have the effect of delaying, deferring or preventing a change in our control and may adversely affect the market price of the common stock and the voting and
other rights of the holders of common stock.

In connection with our underwritten public offering of equity securities on February 21, 2017, we created a series of Preferred Stock called “Series A Preferred Stock.”
None of such shares were issued in such offering. In our April 6, 2018 private placement, we issued 1,000 shares of Series B Preferred Stock (“Series B Preferred”), which
were convertible into 100,000 shares of common stock. All shares of our Series B Preferred have been converted. In our June 26, 2018 public offering of equity securities, we
issued 350 shares of Series C Preferred Stock which were initially convertible into 35,000 shares of common stock. Accordingly, as of the date of this Form 10-K, all shares of
such preferred stock have been fully converted. In connection with the private placements occurring on January 27, 2020, we created two new series of Preferred Stock: Series
D Preferred Stock and Series E Preferred Stock. As of the date of this Form 10-K, 132 shares of Series D Preferred Stock and 333.33 shares of Series E Preferred Stock are
issued and outstanding.

Under the Certificate of Designations for the Series D Preferred Stock, the Series D Preferred Stock has an initial stated value of $1,000 per share (the “Stated Value”).
Dividends accrue at a dividend rate of 9% per annum (subject to increase upon the occurrence (and during the continuance) of certain triggering events described therein) will
accrue  and,  on  a  monthly  basis,  shall  be  payable  in  kind  by  the  increase  of  the  Stated  Value  of  the  Series  D  Preferred  Shares  by  said  amount.  The  holders  of  the  Series  D
Preferred Shares have the right at any time to convert all or a portion of the Series D Preferred Shares (including, without limitation, accrued and unpaid dividends and make-
whole dividends through the third anniversary of the closing date) into shares of the Company’s Common Stock at the conversion price then in effect, which is $2.50 (subject to
adjustment for stock splits, dividends, recapitalizations and similar events and full ratchet price protection). In addition, a holder may at any time, alternatively, convert all, or
any part, of its Series D Preferred Shares at an alternative conversion price, which equals the lower of the applicable conversion price then in effect, and the greater of (x) $1.80
and (y) 85% of the average volume weighted average price (“VWAP”) of the Common Stock for a five (5) trading day period prior to such conversion. Upon the occurrence of
certain triggering events, described in the Certificate of Designations, including, but not limited to payment defaults, breaches of transaction documents, failure to maintain
listing on the Nasdaq Capital Market, and other defaults set forth therein, the Series D Preferred Shares would become subject to redemption, at the option of a holder, at a
125% premium to the underlying value of the Series D Preferred Shares being redeemed.

Under  the  Certificate  of  Designations  for  the  Series  E  Preferred  Stock,  the  Series  E  Preferred  Shares  have  an  initial  stated  value  of  $1,500  per  share  (the  “Stated
Value”). Dividends at the initial rate of 9% per annum will accrue and, on a monthly basis, shall be payable in kind by the increase of the Stated Value of the Series E Preferred
Stock by said amount. The holders of the Series E Preferred Shares have the right at any time to convert all or a portion of the Preferred Shares (including, without limitation,
accrued and unpaid dividends and make-whole dividends through the third anniversary of the closing date) into shares of the Company’s Common Stock at an initial conversion
rate determined by dividing the Conversion Amount by the Conversion Price ($0.13 above the consolidated closing bid price for the trading day prior to the execution of the
Securities Purchase Agreement, dated January 27, 2020, between and the purchasers referenced therein). The Conversion Amount is the sum of the Stated Value of the Series E
Preferred Shares then being converted plus any other unpaid amounts payable with respect to the Series E Preferred Shares being converted plus the “Make Whole Amount”
(the amount of any dividends that, but for the conversion, would have accrued at the dividend rate for the period through the third anniversary of the initial issuance date). The
Conversion Rate is also subject to adjustment for stock splits, dividends recapitalizations and similar events.

The transfer agent and registrar of our common stock is Issuer Direct Corporation. The address of our transfer agent and registrar is 1981 Murray Holladay Road, Suite

100 Salt Lake City, Utah 84117, and its telephone number is (801) 272-9294.

 
 
 
 
 
 
 
 
 
Anti-Takeover Effects of Certain Provisions of Our Charter Documents

Our articles of incorporation and bylaws contain provisions that could delay or prevent changes in control or changes in our management without the consent of our

board of directors. These provisions include the following:

●

●

●

●

●

●

●

●

●

a classified board of directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of a majority of our
board of directors;

no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;

the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death or
removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

the ability of our board of directors to authorize the issuance of additional shares of preferred stock and to determine the terms of those  shares,  including
preferences  and  voting  rights,  without  stockholder  approval,  which  could  adversely  affect  the  rights  of  our  common  stockholders  or  be  used  to  deter  a
possible acquisition of our company;

the ability of our board of directors to alter our bylaws without obtaining stockholder approval;

the required approval of the holders of at least two-thirds of the shares entitled to vote at an election of directors to adopt, amend or repeal our bylaws or
repeal the provisions of our articles of incorporation and bylaws regarding the election and removal of directors;

a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

the requirement that a special meeting of stockholders may be called only by the chairman of the board of directors, the chief executive officer, the president
or the board of directors, which may delay the ability of our stockholders to force consideration of a proposal or  to  take  action,  including  the  removal  of
directors; and

advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted
upon at a stockholders’ meeting, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate
of directors or otherwise attempting to obtain control of us.

These provisions could inhibit or prevent possible transactions that some stockholders may consider attractive.

NASDAQ Capital Market

Our common stock is currently traded on the NASDAQ Capital Market under the symbol “SGLB.”

Nevada Anti-Takeover Law and Charter and Bylaws Provisions

NRS sections 78.378 to 78.3793 provide state regulation over the acquisition of controlling interest in certain Nevada corporations unless the articles of incorporation
or bylaws of the corporation provide that the provisions of these sections do not apply. This statute currently does not apply to our company because in order to be applicable,
we would need to have a specified number of Nevada residents as shareholders, and we would have to do business in Nevada directly or through an affiliate.
