Summary The Company: PART I Sigma is a 10-year-old 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. The public company that in 2010 completed a share exchange transaction with the shareholders of a company that became Sigma Labs in 2010 was incorporated as Messidor Limited in Nevada on December 23, 1985 and changed its name to Framewaves Inc. in 2001. On September 27, 2010, the name was changed from Framewaves Inc. to Sigma Labs, Inc. Thenceforth, the Company developed both a dental implant technology and a munitions technology before narrowing its focus exclusively in 2016 to solving the complex and challenging problem of how to best assure the high quality of metal parts manufactured in laser powder bed additive manufacturing (AM) machines. Sigma and many others, then and now, believed that until this problem was solved, 3D manufacturing of metal parts was not sufficiently scalable 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®. From 2016 through 2020 the Company and its technology co-evolved in transformation that saw the Company step up from being a small research and development operation to reinvent itself as a technology commercialization company in 2017 deploying its alpha technology concept with Aerojet Rocketdyne, Pratt and Whitney, Siemens, Woodward, and other companies to work as a sometimes virtual integrated team with these customers’ R&D personnel and thus to acquire directly from major companies in the market the definition of the specifications of what Sigma’s product would have to be in order to meet commercial industrial standards. Defining these standards included defining the specific product quality data information and analytics requirements of large production manufacturers as well as determining the user-friendly form the product must have. In February 2017, Sigma completed a financing and a simultaneous up list on to the NASDAQ Capital Market, the two actions intended to enable the Company to accelerate product development and commercialization while also having ongoing access to capital. By mid-2018, Sigma had doubled its software development team and in the course of the year developed and integrated its PrintRite3D® Thermal Energy Density™ (TED) and Thermal Energy Planck (TEP) algorithm analytical packages into a hardened commercial industrial product presented at Formnext in November 2018. In 2019, the Company launched its Rapid Test and Evaluation Program (RTE) in order to deploy its new product in a test and evaluation process explicitly designed: (1) to define the test outcome requirements of both end-users and Original Equipment Manufacturers (OEM) required to meet their respective needs in a production setting; and, (2) to be a pathway that Sigma believed would lead to sales of equipment to end-users or of licenses to OEMs subject to the tests and evaluations meeting the upfront stated requirement of the companies with whom tests would be run. In the second Quarter of 2019, Sigma released version 5.0 of PrintRite3D® with a user-friendly interface tool that enables process engineers to drill down into the data and machine operators to better understand and control the process. By year-end of 2019, the RTE results were consistently favorable and we experienced no product failures, however the time required to complete an RTE was longer than expected due to operational issues within the test sites that were beyond our control. Baker Hughes, for whom on-site testing began in April 2019, had ordered a Phase 2 as the final phase ahead of a potentially broader global rollout of the technology to their additive manufacturing machine base. The major service provider, with whom our on-site testing began in March 2019, had also begun its second RTE to start on a different OEM brand from the first RTE tests. Another major OEM whose purchase order for an RTE we announced in August 2019 had only its own brand upon which to test and agreed to complete two simultaneous test units on different models and was thus on a fast track. Airbus was developing on schedule and expected to require a Phase 2 if and after the current RTE met their needs. Materialise, a diverse AM company and an OEM for AM control systems and software, had been Sigma’s first RTE program participant and with whom the Company announced in June 2019 that Sigma had entered into a non-binding Memorandum of Understanding to integrate PrintRite3D® with Materialise’s new MPC AM equipment control system. As stated in the “Recent Events” of this document, on March 5, 2020 the Company announced that Sigma and Materialise have now entered a Joint Sales Agreement to commercialize the integrated product. As defined and disclosed in 2019, Sigma’s mission and challenge in 2020 and beyond is to convert the testing it conducted in 2019 into purchase orders and OEM licenses going forward. Of course, there is no assurance that this mission will be accomplished, even as the goal and strategy are what would be the logical outcomes of successful product demonstrations. In order to further strengthen itself to deliver on its mission to convert successful test and evaluation outcomes into end-user sales and OEM licenses, the Company recruited and hired Mark K. Ruport as of December 3, 2019 to help lead the company forward as Executive Chair. As reported in December, Mr. Ruport is a skilled sales and marketing chief executive who has built three substantial software enterprises. Currently, Sigma is focusing on four markets: (i) end-user for deployment of PrintRite3D® in serial production; (2) 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 powderbed manufactured parts, notwithstanding the design, metal, or brand of equipment upon which parts are manufactured. 4 Additive Metal Manufacturing and the role and need for Sigma’s technology: 3D laser powderbed manufacturing of metal parts is a technology that uses lasers to sculpt parts by welding powdered metals into 3-dimensional (3D) objects and, to date, the quality of these parts can vary from part to part in a single production run, as well as from machine to machine in a production line. Traditional quality assurance methods relying on statistically based post-process inspection methods so well proven by “Subtractive Manufacturing” cannot be used effectively to improve and assure quality of parts manufactured using 3D metal printers. The aforementioned traditional quality assurance methods are based on a manufacturing process that is the opposite of 3D Additive Manufacturing; Subtractive Manufacturing begins with quality-assured already formed pieces of metal as a raw material (not powdered metal as is used as raw material in 3D) and machines it with equipment such as lathes, milling machines, and CNC machines to subtract metal and thus form finished metal parts, or by casting molten metal into molded parts usually to then be further machined. Since the metal used in Subtractive Manufacturing is already of proven quality, the quality of the metal for all parts in a production run is known to be uniform, subject to post process inspection of a statistically determined valid sample size focused primarily on metrology to determine dimensional accuracy rather than metallurgy to determine metal quality. The challenge presented of 3D Additive Manufacturing quality assurance is illustrated by the fact that if a 3D metal manufacturing machine fabricates 10 parts, and quality inspectors then rigorously inspect three of them, the inspectors will have learned about the quality of only the three parts they destroyed or CT-scanned and nothing that is sufficient to confirm or reject the quality of the remaining seven. Quality assurance of 3D Additive metal parts requires high quality sensitive manufacturers to institute procedures to inspect 100% of the parts being made. Sigma believes that the best, indeed, to Sigma’s knowledge, the only known way to attain high yields for both manufacturing quality and cost efficiency is an In-Process-Quality-Assurance (IPQA®) approach that examines each part in real time as it is being manufactured, determines in real time whether it meets quality specifications and permits machine operators to act on the information if a part is beginning to deviate from its design specifications. As evidenced in the marketplace in 2016 and after the pent-up demand of GE, Airbus and others to press forward into advanced 3D metal manufacturing, production took place with the assumption that highly reliable in-process quality assurance capability would likely emerge either from their own internal efforts or be attained through licensing, or acquisition. In the meantime, CT scans and other costly post-process inspection became an accepted cost as initially sustainable in the startup phases of production. However, until companies that utilize 3D production facilities like GE Aviation are able to effectively verify that each part conforms to design specifications of attributes of shape, density, strength and consistency in real-time during the manufacturing process, we believe that such companies will be at risk of letting some substandard parts through and, also, be unable to improve the workflow to high quality cost-optimum yields of 3D printed metal parts. No matter how much acuity and at what cost a suite of post process inspection tools might provide 3D manufactured metal parts, it currently can only assure quality yield by rejecting fully formed parts, and, over time, applying comprehensive ‘reverse engineering’ forensic analyses of each rejected part to identify repeating quality flaws attributable to constants such as location, design, or scan strategy. Once the locations of these repeating flaws are identified, process engineers can act to make the AM equipment deliver better quality by adjusting the computer-based manufacturing instructions of AM equipment to offset the repeating flaws discovered by that deep analyses of individual rejected parts in many manufacturing runs. This prolonged post- process methodology is very costly due to the loss of material and rejected parts as well as post-process analysis labor cost and inspection cost such as CT scanning. Additionally, there still lingers the question of whether or not the post-process inspections were sufficiently granular to assure that flawed parts were not accepted and shipped. We believe that our product, PrintRite3D® version 5.2, which is ‘agnostic’ and can be installed on all major brands of 3D metal laser powderbed printers, solves these problems by determining if each part is being made to the metallurgical quality specifications of the product design as each part is being made. Our software enables 3D prototyping to evolve forward into serial or production 3D manufacturing by providing a software suite with algorithm-based tools that address and overcome quality issues that are specific to 3D Metal Additive Manufacturing and that are not solved using the post-production quality methods developed for subtractive manufacturing along with and newly dependent upon CT scanning. The PrintRite3D® suite has the potential to substantially lower operating costs and can attain higher yields by inspecting parts as they are made and providing machines and their operators actionable information that includes the options of stopping manufacture of given part(s) while operations continue to complete parts that are in specification, thus saving time and money while raising yields. PrintRite3D® also gives operators information from run-to-run that enables them to ‘learn up’ quality for a given machine by using PrintRite3D® data about machine behaviors that can then be offset by making adjustments to power settings directed at a given sector. PrintRite3D ®’s (“TED”) feature supersedes and truncates the “reverse engineering” process of post process inspection described above by providing process engineers the data required to optimize individual machines as well as machines in series in days or weeks and before serial production is launched rather than months after production and rejection rates have accrued in costly quantities. PrintRite3D®’s (“TEP”) feature provides machine operators and engineers with in-process real-time identification of signatures of quality anomalies as they begin to develop and permits terminating or curing a part in process and provides them with alerts that enable the operators to use the anomalies’ signature information to know how to adjust the machine controls to cure the problem, or in rare instances, to terminate the part if its cause is reversable. 5 The emergence of the 3D Metal Printing Market and Sigma’s place in it 3D printing (3DP) or additive manufacturing (AM) is challenging the manufacturing world with the breadth of its technological abilities from rapid design through cost efficient manufacturing to produce complex and unique metal parts. 3D AM technology total industry sales, including all raw materials used reached $1 billion in 2007, jumped to nearly $7.3 billion in 2017, and were expected by Wohlers to hit $26.5 billion by 2021. Sectors of the industry have tended so far to grow in step functions as new methods, processes, and materials have entered the market. Worldwide revenues attributable to 3D manufacturing for metal products were reported at $88.1 million in 2015 (Wohlers Report 2016, 3D Printing and Additive Manufacturing State of the Industry – Annual Worldwide Progress Report). By 2017, Wohlers Report stopped estimating annual 3D metal parts revenue, stating that too much of the revenue is proprietary information and unavailable from aerospace and similar high-tech sectors. Powdered metal suppliers to the AM metal industry surveyed by Wohlers for their growth forecasts for 2017 for the raw materials used in metal AM parts manufactured averaged expectations of a 59% increase for 2017. According to Sigma’s experience in costing and pricing the manufacturing of AM metal parts, as confirmed by consultation with other service providers, the total powdered metal sales forecast for 2017 is enough raw material to produce a “retail value” of the metal parts of ~$800 million in 2017. Wohler estimates that the fastest growing sector of the total 3D market into the 2020s is and will be 3D metal printing at a CAGR averaging 30%. On another vector, according to Wohlers, an estimated 1,768 metal AM machines were sold in 2017, an increase of 79% over 2016, and the 2,297 AM Metal machines sold in 2018, an CAGR of 30% over 2017. As large established companies including Toshiba, HP, Lenovo, Canon and Ricoh in the course of 2016-2017 announced products or intents of entry in AM manufacturing, Electro Optical Systems (“EOS”), a well-established vendor of AM manufacturing equipment opened a new plant in January 2018 that, according to EOS, doubled its 2017 capacity to 1,000 units per year. SLM Solutions AG also reportedly expanded into a new factory during this period. In the same period, over $1 billion growth capital and consolidation capital was invested in the metal sector. General Electric spent >$1.4 Billion in 2016-2017 acquiring Arcam and Concept Laser thus securing a source of supply for itself as well as a new OEM capital equipment business. In the same period GE also invested >$100 Million in in Desktop Metal. In October 2018 General Electric announced that it had manufactured and shipped its 30,000th 3D manufactured fuel nozzle, while Airbus was targeted to grow to taking delivery of up to ~30 tons of metal parts per month by December 2018. 3D metal printers are seeing rapid adoption, with an installed base of 11,000 globally, with 2,297 sold in 2018 alone at an ASP of $413,000. Extending data and trends reported by Wohlers above, Sigma’s possible addressable market 2021-2027 is approximately $2 billion – or a potential $100m revenue for every 5% of market share. The figures in this paragraph are extrapolations from Wohlers and SmarTech data and forecasts of the total available market for Sigma products; the calculation that 5% of that total available market is $100m is intended as metric to make the scale of market opportunity more understandable, and it is not a forecast. We believe there is potential for our PrintRite3D® software to be incorporated into a significant percentage of 3D metal printing devices made by companies like Additive Industries, ARCAM, Concept Laser, DMG Mori, Electro-Optical Systems (“EOS”), SLM, Trumpf Industries, Farsoon, Renishaw, Sodick, and others. Third Party Competition and Sigma’s Intellectual Property Safeguards Sigma is engaged with large companies in several industries including aerospace, defense, oil and gas, bio-medical, and power generation because both we, and they, agree that they need a common quality standard and third party quality assurance tools for 3D metal printing that applies to all laser powderbed-made parts regardless of which machine, design, or metal was employed. To date, we are unaware of any meltpool monitoring products that compete with PrintRite3D that can meet those criteria. Sigma’s thermal data gathering, and analytical tools provide quality information metrics that correlate to measures of internal metal part design, conformity, uniformity, and characteristics such as porosity, unsintered material etc. The primary competition to PrintRite 3D is varying iterations of Optical Tomography (OT). Optical Tomography develops optical data and computer analysis thereof sometimes linked to simulation tools to predict quality. OT technology does not provide universal thermal-data based metrics of metal quality that Sigma’s thermal data provides, and which are fundamental to confirming or rejecting parts based on measurable consistency of material properties. Sigma began its investigation and research into optical and thermal data collection and measurement for quality assurance and intervention approximately 5 years ago and began to develop its intellectual property protection at that time also. The international IP law firm, Kilpatrick Townsend & Stockton LLP, has advised the Company on building the nets and walls of its patent portfolio, trade secrets, trademarks, etc. and filed and prosecuted patents as the Company has grown its body of intellectual property. 6 Sigma Labs, Inc. Patent Portfolio Jurisdiction Granted In Process 11 - - - - - - 11 US PCT EP Germany China Japan Korea Total 11 2 4 4 1 1 1 24 Total 22 2 4 4 1 1 1 35 Based upon the evidence of competitors’ product claims and features reviewed by Sigma to date, it appears to us that Sigma’s solution to the quality problems of 3D metal printing is a significantly different technological approach than that of our principal known competition. It continues to appear to us that the intellectual property protection of PrintRite3D’s acuity, meaningful metrics of thermal data correlated to part quality, and usability of its software accord Sigma freedom to operate with its technology, and may be a significant barrier to entry to competitors switching over to try to pursue the technology path traveled by Sigma. Notwithstanding the foregoing, we do understand that technology development is fraught with cases of new approaches and new technologies emerging and surpassing existing intellectual property protections that looked and were powerful until a form of competition materialized; there is no assurance that such an event will not take place adversely for Sigma. Recent Developments On March 23, 2020, we announced that we were awarded two new U.S. Patents: ● U.S. Application No.: 16/234,333 Titled: Systems and Methods for Additive Manufacturing Operations; and ● U.S. Application No.: 16/282/004 Titled: Systems and Methods for Measuring Radiated Thermal Energy During an Additive Manufacturing Operation. With the addition of these new patents, our intellectual property portfolio is now comprised of eleven issued and twenty-four pending patents. On March 5, 2020, we announced that we have agreed to evolve our previously announced memorandum of understanding (MOU) to cooperate on the integration of the Materialise MCP Controller with our PrintRite3D® technology and have agreed to enter into a binding joint sales agreement to begin beta customer commercialization of the integrated PrintRite3D® and Materialise Control Platform (MCP) product. On March 2, 2020, we gave notice that a Special Meeting of Stockholders will be held at 3900 Paseo del Sol, Santa Fe, New Mexico 87507, at 10:00 AM, local time, on March 27, 2020 for the purposes set forth in the proxy statement filed by the Company with the Securities and Exchange Commission on March 2, 2020. On February 26, 2020, we filed a Certificate of Change to its amended and restated articles of incorporation with the Nevada Secretary of State. This filing effected a 1-for-10 reverse stock split (the “Reverse Split”) of the Company’s Common Stock and a corresponding decrease in the number of shares of the Company’s Common Stock that the Company is authorized to issue, effective as of 11:59 pm on February 27, 2020. The Reverse Split combined each ten shares of the Company’s issued and outstanding Common Stock into one share of Common Stock. No fractional shares were issued in connection with the Reverse Split, and any fractional shares resulting from the Reverse Split were rounded up to the nearest whole share. All stock options, warrants, shares issuable upon conversion of the Company’s preferred stock and stock awards of the Company outstanding immediately prior to the Reverse Split will be adjusted in accordance with their terms. On February 19, 2020, we were informed by Frank Garofalo that he has resigned as a director of the Company, effective February 19, 2020. Mr. Garofalo has advised the Company that he resigned in order to cause the Company to regain compliance with Nasdaq’s majority of independent director requirement as set forth in Nasdaq Listing Rule 5605(b)(1), and not due to a disagreement with the Company on any matter regarding its operations, policies or practices. On January 27, 2020, we entered into a Securities Purchase Agreement (the “Institutional SPA”) with certain institutional investors (the “Institutional Investors”). Pursuant to the Institutional SPA, the Company issued and sold to each Institutional Investor shares of the Company’s Series D Convertible Preferred Stock (the “Series D Preferred Stock”), warrants to purchase the Company’s Common Stock (the “Institutional Common Warrants”) and warrants to purchase the Series D Preferred Stock (the “Preferred Warrants”) for a total gross purchase price of $1,600,000. At the closing on January 28, 2020, the Company issued to the Institutional Investors an aggregate of 1,640 shares of the Series D Preferred Stock (the “Series D Preferred Shares”), Institutional Common Warrants to purchase up to an aggregate of 779,600 shares of Common Stock and warrants to purchase an aggregate of 6,156 of additional Series D Preferred Stock. Concurrently with the foregoing private placement, we also sold 333.33 shares of our Series E Preferred Stock and warrants to purchase 48,544 shares of our common stock for a total gross purchase price of $500,000. The Series E Preferred Stock is initially convertible into 48,544 shares of Common Stock. On December 3, 2019, we entered into an employment letter agreement with Mark Ruport, effective as of December 3, 2019, pursuant to which Mr. Ruport has 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, effective as of December 3, 2019, with a term expiring at the 2021 annual meeting of stockholders. 7 On November 19-22, 2019, we demonstrated the latest version of our proprietary PrintRite3D® Real-Time Melt Pool Analytics software platform in conjunction with Materialise NV at the Formnext 2019 conference in Frankfurt, Germany. Materialise invited our Chief Technology Officer to present on “Integration of PrintRite3D Melt Pool Monitoring Software with Materialise’s Machine Control Platform (MCP) for Advanced Process Control” at Materialise’s booth. On November 5, 2019, we announced that we have partnered with a Japanese high-end manufacturer of state-of-the-art machine tools, electrical discharge machines (EDM) and 3D printing products, for a test and evaluation program of Sigma Labs’ PrintRite3D® real time melt pool analytics. On October 23, 2019, we announced that we have been awarded a contract by VTT Technical Research Centre of Finland Ltd, an impartial, state-owned non-profit research and technology organization with the mission to support economic competitiveness, societal development and innovation in Finland, to install our proprietary PrintRite3D® Real-Time Melt Pool Analytics software platform at the VTT 3D metal printing facility. On August 13, 2019, we announced that we have been selected by a major international OEM machine manufacturer to install our proprietary PrintRite3D® products. As part of the agreement, the OEM will complete our Rapid Test and Evaluation program and will install the PrintRite3D® in two different countries for analysis and proof-of- performance purposes. On August 2, 2019, we closed a public offering of equity securities in which we issued 287,500 shares of common stock resulting in net proceeds of $1,971,000. On July 30, 2019, we announced that we will work with Airbus to complete a Test and Evaluation Program of our new PrintRite3D® version 5.0 hardware and software followed by a validation phase on a powderbed fusion printer. On June 18, 2019, we announced that we signed a non-binding Memorandum of Understanding with Materialise NV to cooperate in the integration of their MCP Controller with our PrintRite3D® technology. Combining the sophisticated control technology with in-situ process monitoring for metal additive manufacturing will give customers maximal control on the production process, allowing them to become even more productive. On May 21-23, 2019, we launched Version 5.0 of our PrintRite3D® platform at the RAPID+TCT 2019 Additive Manufacturing Conference in Detroit. On April 30, 2019, we announced that the Company’s PrintRite3D® software has been shown to ensure process consistency and product quality in metal additive manufacturing, according to a research study sponsored by the Defense Advanced Research Project Agency (DARPA) Open Manufacturing Program and conducted in tandem with Honeywell Aerospace at Honeywell’s Advanced Manufacturing Engineering Center. The paper, titled “LPBF [Laser Powder Bed Fusion] Right the First Time-the Right Mix Between Modeling and Experiments,” discusses the validation involved in manufacturing a challenging metal component. On March 26, 2019, we announced the appointment of the Company’s new Business Development Manager, America’s, who will be responsible for developing key accounts through the Company’s Rapid Test and Evaluation Program and for bringing PrintRite3D Inspect® into deployment across serial production operations in North and South America. Intellectual Property We regard our patents, trademarks, domain names, trade secrets, know-how, and other intellectual property as critical to our success. We rely on a combination of patent, trademark, trade secret, other intellectual property law, confidentiality procedures, and contractual provisions with employees, partners, and others to protect the technology and other proprietary rights, information and know-how that comprise the core of our business. The chart below summarizes our issued patents. We are currently prosecuting twenty-four foreign and U.S. patent applications related to our IPQA® technology and rapid qualification of additive manufacturing for metal parts. There is no guarantee that the patent applications we have submitted will issue or that if issued, they will offer adequate protection under applicable law. 8 Title Controlled Weld Pool Volume Control of Welding Processes Structurally Sound Reactive Materials Composite Projectile Methods and Systems for Monitoring Additive Manufacturing Processes Systems and Methods for Additive Manufacturing Operations Material Qualification System and Methodology Optical Manufacturing Process Sensing and Status Indication System Systems and Methods for Measuring Radiated Thermal Energy During an Additive Manufacturing Operation Optical Manufacturing Process Sensing and Status Indication System Systems and Methods for Additive Manufacturing Operations* Systems and Methods for Measuring Radiated Thermal Energy During an Additive Manufacturing Operation* Type US Utility US Utility US Utility US Utility US Utility US Utility US Utility US Utility US Utility US Utility US Utility Patent No. or Application No. Expiration Date 8,354,608 8,372,224 8,359,979 9,999,924 10,207,489 10,226,817 10,317,294 10,479,020 10,520,372 16/234,333 16/282,004 3/16/31 10/15/30 3/21/27 5/11/36 6/20/37 4/26/37 5/2/35 8/1/38 3/25/35 9/30/36 2/21/39 *Patents granted; however, patent numbers have not yet been issued. Expiration dates are therefore estimated. Government Regulation 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 20, 2020, we do not have any active contracts with government agencies. During fiscal year 2019, we did not enter into any contracts with government agencies, nor do we seek to do so in the future. Employees As of December 31, 2019, we had 21 full-time employees. We continue to search for additional, qualified personnel, to support our expanding operations in the area of IPQA® for AM. Properties We lease approximately 3,872 square feet of space at 3900 Paseo del Sol, Santa Fe, New Mexico 87507, including 1,945 square feet of office space at units, C-14, C- 15, C-16, C-17, C-18, C-20, C-21 and D-34 for a total monthly rent expense of approximately $4,240 under the lease, and 1,927 square feet of warehouse / production space at units E-38, E-40 and E-42, for a total monthly rent expense of approximately $2,275 under the lease, which expire between May 31, 2020 and July 31, 2020. We believe that our facilities are suitable for our current needs. We currently intend to renew such leases, but we are evaluating the need for a larger space as we grow. Corporate Information 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 information contained therein, or connected thereto, are not and are not intended to be incorporated into this Annual Report on Form 10-K. 9 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. ITEM 1A. RISK FACTORS. Investing in our securities involves a high degree of risk. 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. You should carefully consider the risks described below, as well as the other information in this annual report, including our financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before deciding whether to invest in our securities. 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 securities could decline, and you could lose all or part of your investment. 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 have a limited operating history, 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 for the years ended December 31, 2019 and 2018 were $6,320,849, and $5,574,163, respectively. As of December 31, 2019, our accumulated deficit was $26,095,594. 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, 2019 and December 31, 2018 were $402,446 and $388,574, respectively, and our operating expenses for those periods were $6,211,830 and $5,687,271, 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. 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. Subject to the satisfaction of certain equity conditions, we have the right to force the exercise of a portion of the warrants to purchase our Series D Preferred Stock which will result in gross cash proceeds of $500,000. Additionally, if all of the remaining warrants to purchase shares of Series D Preferred Stock and Common Stock are exercised by the holders thereof, the potential gross cash proceeds to us will be $13,298,100. Depending on the amount, if anything, we receive from such exercises and the timing thereof, and the amount of revenues we are able to generate, we may 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. Our limited operating history makes evaluation of our business difficult. We commenced business operations in 2010 and 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 relatively short 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. 10 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 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. Our small number 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. We are subject to government audits, and our failure to comply with applicable laws, regulations and standards could subject us to civil and criminal penalties and administrative sanctions. The government agencies we contract with have the authority to audit and investigate our contracts with them. As part of that process, a government agency may review our performance on a contract, our pricing practices, our cost structure and our compliance with applicable laws, regulations and standards. If the agency determines that we have improperly allocated costs to a specific contract, we will not be reimbursed for those costs and we will be required to refund the amount of any such costs that have been previously reimbursed. If a government audit identifies improper activities by us or we otherwise determine that these activities have occurred, we could be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeitures of profits, suspension of payments, fines and suspension or disqualification from doing business with the government. Any adverse determination could adversely impact our ability to bid for Request for Proposals (“RFPs”) in one or more jurisdictions. 11 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 nine years, and we expect to grow in the near future as our business develops and becomes 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 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 our Executive Chairman, President and Chief Executive Officer and other key personnel, and the loss of any of these individuals could harm our business. We depend on Mark Ruport, our Executive Chairman, John Rice, our President and Chief Executive Officer, as well as 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; 12 ● ● ● ● 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. 13 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. We filed thirty-three foreign and U.S. patent applications pertaining to our IPQA® technology and rapid qualification of additive manufacturing for metal parts. We have been awarded eleven U.S. patents. However, the efforts we have taken to protect our proprietary rights may not be sufficient or effective. 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 services are subject to government regulation, changes in which may have an adverse effect on us. Our business activities subject us to a variety of federal, state and local laws and regulations. For example, we could be required to comply with applicable provisions of the International Traffic in Arms Regulations (“ITAR”), as well as other export controls and laws governing the manufacture and distribution of munitions technology. Changes in the laws and regulations applicable to our business activities may have an adverse effect on our operations and profitability by making it more expensive and less profitable for us to do business. Additionally, the market for our services depends largely on federal and state legislative programs. These programs can be modified or amended at any time by acts of federal and state governments. Further, if additional programs are not proposed or enacted, or if previously enacted programs are challenged, repealed or invalidated, our growth strategy could be adversely impacted. 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 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. 14 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 coronavirus outbreak. In December 2019, the 2019 novel coronavirus surfaced in Wuhan, China. The World Health Organization declared a global emergency on January 30, 2020, with respect to the outbreak and several countries, including the United States have initiated travel restrictions, and residents of several territories are currently under so-called Stay- at-Home orders. The impacts of the outbreak are unknown and rapidly evolving. A widespread health crisis could adversely affect the global economy, resulting in an economic downturn that could impact demand for our technology and products. To date the outbreak has not had a material adverse impact on our operations. However, the future impact of the outbreak is highly uncertain and cannot be predicted and there is no assurance that the outbreak will not have a material adverse impact on the future results of the Company. The extent of the impact, if any, will depend on future developments, including actions taken to contain the coronavirus. Risks Related to Our Securities The price of our securities could be subject to volatility related or unrelated to our operations, which could result in substantial losses for our stockholders. Between January 1, 2019 and December 31, 2019, the trading price of our common stock has ranged from a low of $5.00 to a high of $24.10 and could be subject to wide fluctuations in the future in response to various factors, some of which are beyond our control. The trading price of the warrants that we issued in our recent public offering could be subject to similar fluctuations as a result of such factors. 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. 15 An active trading market in our securities may not develop, and you may therefore have difficulty selling your securities at a price that you determine is satisfactory. Although our common stock and the 2017 warrants are listed on The NASDAQ Capital Market, our common stock and warrants trade infrequently and in low volumes. There is no assurance that such securities will trade in the public market at or above a price that you consider acceptable. Furthermore, there is no assurance that an active trading market for any of our securities will develop or be sustained. If an active market for our securities does not develop or is not maintained, it may be difficult for you to sell your securities 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 satisfy or regain compliance with the continued listing requirements of The Nasdaq Capital Market. For example, there is no assurance that we will be able to satisfy all of the quantitative continued listing requirements, including the minimum stockholders’ equity requirement of at least $2,500,000 for continued listing on The Nasdaq Capital Market. On April 8, 2019, Nasdaq notified us that we did not comply with the minimum $2,500,000 stockholders’ equity requirement for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(1). In our Form 8-K filed on September 4, 2019, we disclosed that we had regained compliance with such rule as a result of our August 2019 underwritten public offering. On October 8, 2019, we received a letter from Nasdaq notifying us that, as a result of such offering, Nasdaq determined that we were in compliance with the minimum $2,500,000 stockholders’ equity requirement for continued listing on The Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(1), but that if we do not demonstrate continued compliance with such rule as of December 31, 2019, the Company’s common stock may be subject to delisting. On January 7, 2020, we received a letter from Nasdaq notifying the Company that we are no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. On February 4, 2020 we submitted to Nasdaq our plan to regain compliance. On March 18, 2020, we received a letter from Nasdaq notifying us that our plan was accepted. Accordingly, the Company must provide an update to Nasdaq by April 15, 2020 regarding the status of any exercises of warrants issued in the January 2020 private placement, and by June 30, 2020, the Company must evidence compliance with the stockholders’ equity requirement. There can be no assurance that the Company will be able to regain compliance. If the Company does not evidence compliance by June 30, 2020, or if the Company fails to satisfy another Nasdaq requirement for continued listing, Nasdaq could provide notice that the Company’s common stock will become subject to delisting. In such event, Nasdaq rules would permit the Company to appeal the decision to reject the Company’s 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 recent public and private 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. 16 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, 2019, we had 1,403,759 outstanding shares of common stock. Sales of a large number of the shares described in the preceding sentence 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. On January 27, 2020, we entered into a Securities Purchase Agreement (the “SPA”) with certain institutional investors (the “Institutional Private Placement”). Pursuant to the SPA, we issued and sold 1,640 shares of the Company’s Series D Convertible Preferred Stock, warrants to purchase 779,600 shares of the Company’s Common Stock (the “Common Warrants”) and warrants to purchase 6,156 shares of the Series D Preferred Stock (the “Preferred Warrants”). The Series D Preferred Stock has an initial stated value of $1,000 per share (the “Stated Value”). Dividends at a dividend rate of 9% per annum of Stated Value will accrue and, on a monthly basis, will be payable in kind by the increase of the Stated Value of the Series D Preferred Shares by such amount. The holders of the Series D Preferred Shares will have the right to convert the Series D Preferred Shares (including, without limitation, make-whole dividends (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)) into shares of the Company’s Common Stock (the “Conversion Shares”) at the conversion price then in effect (initially $10.00). A holder may at any time convert the Series D Preferred Shares at an alternative conversion price, equal to 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 our Common Stock for a five (5) trading day period prior to such conversion. The initial exercise price of the Common Warrants is $10.00. The Preferred Warrants have a term of one year from the date that the securities referenced in the SPA become fully tradeable. We have the right to force the exercise of up to 512 Preferred Warrants subject to certain equity conditions, which would result in gross proceeds to us of approximately $500,000. The initial exercise price for the Preferred Warrants is $975 per share. As a result of the Institutional Private Placement, if all the Series D Preferred Shares are converted at the lowest possible conversion price ($1.80) and all the Common Warrants are exercised at the initial exercise price of $10.00 per share, we will be obligated to issue an aggregate of 6,280,111 shares. A registration statement covering the resale of such shares has been declared effective, and, as of March 20, 2020, 217,667 shares have been issued pursuant to the conversion of Series D Preferred Shares and sold into the public market. We anticipate that the holders of the Series D Preferred Shares will continue to convert their preferred shares and publicly sell the resulting common shares which will likely put pressure on the market price of our stock. Concurrently with the Institutional Private Placement, we also sold 333.33 shares of our Series E Preferred Stock and warrants to purchase 48,544 shares of our common stock. The Series E Preferred Stock is initially convertible into 48,544 shares of Common Stock. We also issued to Dawson James Securities, Inc. our placement agreement in these private placements, warrants to purchase up to 17,004 shares 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. 17 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 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 recently issued Series D and Series E Preferred Stock and 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. As indicated above, we have recently completed the sale of shares of our Series D and Series E Preferred Stock together with warrants to purchase our common stock and additional shares of our Series D Preferred Stock. In addition to the possible negative effect on the market price of our common shares resulting from the public sale or perceived sale of common shares issuable upon conversion or exercise of these securities, the Certificate of Designations for the Series D Preferred Stock provides that upon occurrence of certain triggering events described in the Certificate, including but not limited to, payment defaults, breaches of the transaction documents pertaining to the Series D Preferred Stock and failure to maintain listing on the NASDAQ Capital Market, the Series D Preferred Shares would become subject to redemption, at the option of the holder, at a 125% premium to the underlying value of the Series D Shares being redeemed. Any redemption would require a significant cost outlay by us. 18  ITEM 1B. UNRESOLVED STAFF COMMENTS. Not applicable. ITEM 2. PROPERTIES. We lease approximately 3,900 square feet of space at 3900 Paseo del Sol, Santa Fe, New Mexico 87507, including 1,945 square feet of office space at units, C-14, C- 15, C-16, C-17, C-18 C-20,C-21 and D-34 for a total monthly rent expense of approximately $4,240 under the lease, and 1,927 square feet of warehouse / production space at units E-38, E-40 and E-42, for a total monthly rent expense of approximately $2,275 under the lease. The leases expire on July 31, 2020, except for unit C-18 which expires on May 31, 2020. We believe that our facilities are suitable for our current needs, but we are evaluating the need for a larger space as we grow. ITEM 3. LEGAL PROCEEDINGS. We are not currently a party to any legal proceedings. However, we may occasionally become subject to legal proceedings and claims that arise in the ordinary course of our business. It is impossible for us to predict with any certainty the outcome of pending disputes, and we cannot predict whether any liability arising from pending claims and litigation will be material in relation to our financial position or results of operations. ITEM 4. MINE SAFETY DISCLOSURES. Not Applicable. PART II ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES. Market Information Our common stock was quoted for trading on the OTCQB under the symbol “SGLB” prior to February 15, 2017, when our common stock began trading on The NASDAQ Capital Market under the symbol “SGLB.” Shareholders As of March 20, 2020, there were approximately 533 holders of record of our common stock based on information provided by our transfer agent. Dividends We have not paid any dividends on our common stock to date and do not anticipate that we will pay dividends in the foreseeable future. Any payment of cash dividends on our common stock in the future will be dependent upon the amount of funds legally available, our earnings, if any, our financial condition, our anticipated capital requirements and other factors that the board of directors may think are relevant. However, we currently intend for the foreseeable future to follow a policy of retaining all of our earnings, if any, to finance the development and expansion of our business and, therefore, do not expect to pay any dividends on our common stock in the foreseeable future. However, we have paid dividends on our preferred stock pursuant to an agreement with investors and may do so in the future pursuant to future financing agreements, if any. Pursuant to the Series D Preferred Stock Certificate of Designations, the Company may not declare or pay any cash dividend or distribution on any of its capital stock, other than as required by the Certificate of Designations. 19 Recent Sales of Unregistered Securities Not applicable. Repurchase of Shares We did not repurchase any of our securities during the fiscal year ended December 31, 2019. ITEM 6. SELECTED FINANCIAL DATA. Not applicable to a “smaller reporting company” as defined in Item 10(f)(1) of SEC Regulation S-K. ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Critical Accounting Policies 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. 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. Results of Operations Year Ended December 31, 2019 Compared to the Year Ended December 31, 2018. We expect to generate revenue primarily by selling and licensing our IPQA technologies, selling technical support services, and selling specialty parts and studies to businesses that seek to improve their manufacturing production processes and production-run quality yields. 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 if key prospective customers continue to move from AM metal prototyping to production. During the fiscal year ended December 31, 2019 (“fiscal 2019”), we generated an aggregate of $402,446 in revenues, as compared to an aggregate of $388,574 in revenues generated by us in the fiscal year ended December 31, 2018 (“fiscal 2018”). The primary contributor to the $13,872 increase was an increase in new PrintRite3D® 5.0 system sales of $145,097 partially offset by decreases in contract AM service sales and government program work of $78,387 and $51,000, respectively. Our cost of revenue for fiscal 2019 was $574,301 compared to $270,107 during the same period in 2018, an increase of $304,194. The increase is primarily due to increased PrintRite3D® 5.0 system sales, and additional travel and labor costs associated with the on-site and remote collaboration involved in the Company’s Rapid Test and Evaluation program. 20 Sigma’s total operating expenses for fiscal 2019 were $6,211,830 as compared to $5,687,271 for fiscal 2018, a $524,559 increase. In fiscal 2019, salaries and benefits costs were $2,354,329 as compared to $2,056,584 for the same period in 2018. The $297,745 increase resulted primarily from the addition of six employees between the third quarter of 2018 and December of 2019. Stock-based compensation for fiscal 2019 was $797,238 compared to $1,145,530 for the same period in 2018. This $348,292 decrease resulted primarily due to the vesting of options granted to our former CEO in connection with his amended employment agreement in 2018. During fiscal 2019, Sigma incurred research and development expenditures of $647,994 compared to $493,410 in the same period of 2018. The $154,584 increase resulted from an increase in purchases of component parts, upgraded servers and specialized equipment plus an increase in software and algorithm consultant costs as part of our continued concentrated acceleration of technology development and enhancements to our PrintRite3D® 5.0 product suite. Sigma’s public company and investor relation fees incurred in fiscal 2019 were $703,710 compared to $633,035 in fiscal 2018. The increase in the comparative expenditures results primarily from shares of common stock issued to our new investor relations firm of $17,110 and an increase in advertising expenses of $80,450, due to enhancements to marketing programs and materials, website redesign and upgrades, and advertisements in trade publications Legal and professional service fees paid in fiscal 2019 were $664,403 compared to $564,854 paid in fiscal 2018. The increase of $99,549 is primarily attributable to an increase in consulting fees due to the addition of an engineering consultant and an investor relations consultant in 2019. During fiscal 2019, Sigma’s office expenses were $692,881 compared to $466,657 in the same period of 2018. The $226,224 increase in these expenditures resulted primarily from $57,039 in additional office space rent and supplies costs related to the aforementioned addition of six employees, and from $92,679 of additional travel expenses in 2019 related to both a more aggressive outreach to prospective OEM, service bureau and end user customers and our continued expansion into the European market. Further contributing to this increase is the amortization of our prepaid three-year membership in the UK’s National Center for Additive Manufacturing (“NCAM”) of $52,000 during fiscal 2019. In fiscal 2019, our net other income & expense was net income of $62,836 compared to net expense of $5,359 in 2018. The 2019 net income was comprised of incentives from the State of New Mexico of $51,887 and net interest income of $18,761, partially offset by interest expense of $8,865. The 2018 expense was comprised of a $36,733 loss on disposal of assets, partially offset by interest income of $35,178. Sigma’s net loss for fiscal 2019 increased $746,686 overall and totaled $6,320,849, as compared to a net loss of $5,574,163 for fiscal 2018. The 2019 net operating loss component of the overall loss being $814,881 higher than in 2018 and the other income and expenses component being a $68,195 lower loss. Liquidity and Capital Resources As of December 31, 2019, we had $86,919 in cash and a working capital deficit of $98,315, as compared to $1,279,782 in cash and a working capital surplus of $1,052,017 as of December 31, 2018. On January 27, 2020, the Company closed a private offering of equity securities resulting in net proceeds of approximately $1,711,124 after deducting commissions and other offering expenses payable by the Company. 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. On April 6, 2018, the Company closed a private placement of equity securities resulting in net proceeds of approximately $920,000, after deducting commissions and other offering expenses payable by the Company. On June 26, 2018, the Company closed a public offering of equity securities resulting in net proceeds of approximately $2,139,000, after deducting commissions and other offering expenses payable by the Company. On March 15, 2019, the Company closed a public offering of equity securities resulting in net proceeds of approximately $1,679,230 after deducting commissions and other offering expenses payable by the Company. In May 2019, the Company closed a private placement of equity securities resulting in net proceeds of approximately $515,000, after deducting placement agent commissions and other offering expenses payable by the Company. In August 2019, the Company closed a public offering of equity securities resulting in net proceeds of approximately $1,971,000, after deducting placement agent commissions and other offering expenses payable by the Company. In September 2019, Aegis Capital Corp. partially exercised its over-allotment option granted by the Company in the foregoing August 2019 public offering, resulting in net proceeds of $148,800 after deducting placement agent commissions. 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. Subject to the satisfaction of certain equity conditions, we have the right to force the exercise of a portion of the warrants to purchase our Series D Preferred Stock which will result in gross cash proceeds of $500,000. Additionally, if all of the remaining warrants to purchase shares of Series D Preferred Stock and Common Stock are exercised by the holders thereof, the potential gross cash proceeds to us will be $13,298,100. Depending on the amount, if anything, we receive from such exercises and the timing thereof, and the amount of revenues we are able to generate, we may 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. 21 During 2020, we expect to sustain our operations and our commercialization and marketing efforts without material increase in our cash burn rate. We expect that enhancements of our IPQA®-enabled PrintRite3D® technology that were developed in fiscal 2018 and 2019 and brought to market tests and evaluations, commencing in January 2019 and then enhanced with version 5.0 in May 2019 will enable us to commercialize this technology into the AM metal market in 2020. 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. Net Cash Used in Operating Activities Net cash used in operating activities in 2019 increased to $5,514,805 from $3,762,971 in 2018 which is an increase in cash used of $1,751,834. This increase is primarily attributable to: (1) an increase in our net loss of $747,686; (2) lower stock-based compensation expense of $348,292 due to the vesting of options granted to our previous CEO in 2018; (3) an increase in prepaid expenses of $184,472 primarily as a result of our three-year membership in the UK’s National Centre for Additive Manufacturing (“NCAM”), and (4) an increase in inventory of $333,788 due to the growth of our RTE program in 2019. Net Cash Used/Provided by Investing Activities Net cash used by investing activities during fiscal 2019 was $85,798, which compares to cash provided by investing activities during the same period of 2018 totaling $403,672. The decrease is primarily due to the receipt of cash from loan repayments in 2018 from loans made in 2017. Net Cash Used/Provided by Financing Activities Cash provided by financing activities during fiscal 2019 increased to $4,407,740 from $3,123,407 during the same period in 2018, an increase of $1,284,333 as a result of increased net proceeds from our 2019 private and public offerings over 2018. We have no credit lines as of March 24, 2020, nor have we ever had a credit line since our inception. Our ability to continue to fund our liquidity and working capital needs will be dependent upon the success of our efforts to generate revenues from existing and future PrintRite3D®-proof-of-concept contracts, follow-on contracts resulting from successful proof-of-concept engagements, possible strategic partnerships, and by obtaining additional capital from the sale of securities or by borrowing funds from lenders to fulfill our business plans. If we issue additional equity or debt securities, stockholders may experience additional dilution or the new equity securities may have rights, preferences or privileges senior to those of existing holders of our common stock. There is no assurance that we will be successful in obtaining additional funding. The Company is unable to predict the effect, if any, that the novel coronavirus outbreak may have on its access to the financing markets. 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. 22 Inflation and changing prices have had no effect on our continuing operations over our two most recent fiscal years. We have no off-balance sheet arrangements as defined in Item 303(a) of Regulation S-K. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. Not applicable to a “smaller reporting company.” ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA. Financial Statements are referred to in Item 15, listed in the Index to Financial Statements and filed and included elsewhere herein as a part of this Annual Report on Form 10-K.+ ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE. None. 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 in the early stage of our business, with limited revenues and employees. Management’s Annual 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, 2019. 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. 23 This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to SEC rules that permit us to provide only management’s report in this annual report. There have been no changes in our internal controls over financial reporting during the fourth quarter of the year ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Director Independence Our Board of Directors currently consists of five members. As a result of his appointment as Chief Executive Officer, Mr. Rice is not considered an independent director. As a result of his appointment as Executive Chairman, 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 exists, 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 2021 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 2020 annual meeting of stockholders. Our Board of Directors appointed Mark Ruport as Executive Chairman of the Board on December 3, 2019. 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. 28 Leadership Structure of the Board 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. On December 3, 2019, our Board of Directors appointed Mr. Ruport as Executive Chairman of the Board. The Chairman of the Board and the Executive Chairman preside at all meetings of our Board of Directors and exercise and perform such other powers and duties as may be assigned to them 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, but periodically considers whether combining, or separating, the role of Chairman and Chief Executive Officer is appropriate. At this time, our Board is committed to the combined role given the circumstances of our Company, including Mr. Rice’s knowledge of our Company’s strategy, and has also determined at this time that having an Executive Chairman together with a Chairman is in the best interest of the Company based on Mr. Ruport’s leadership experience in the technology industry. Our Board believes that having a Chairman who also serves as the Chief Executive Officer allows timely communication with our board on company strategy and critical business issues, facilitates bringing key strategic and business issues and risks to the Board’s attention, avoids ambiguity in leadership within the Company, provides a unified leadership voice externally and clarifies accountability for Company business decisions and initiatives. However, our Board of Directors continually evaluates our leadership structure and could, in the future, decide to separate 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, 2019, the Board of Directors held four 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 2019 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.

The members of our Audit Committee are Messrs. Duitch, Battinelli and Summers, and Mr. Duitch serves as the chairperson of the committee. Our Board of Directors has determined that each of Messrs. Duitch, Battinelli and Summers is an independent director under NASDAQ rules and under SEC Rule 10A-3. All members of our Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and NASDAQ. Our Board of Directors has determined that each member of our Audit Committee is an “audit committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable NASDAQ rules and regulations. The Audit Committee met four times during 2019. Compensation Committee The Compensation Committee’s responsibilities include: ● ● ● ● ● ● ● annually reviewing and approving corporate goals and objectives applicable to CEO compensation; determining our CEO’s compensation; reviewing and approving, or making recommendations to our board with respect to, the compensation of our other executive officers; overseeing an evaluation of our senior executives; overseeing and administering our equity incentive plans; reviewing and making recommendations to our board with respect to director compensation; and reviewing and discussing annually with management our “Compensation Discussion and Analysis” when it is required by SEC rules to be included in our Proxy Statements.

Duitch, Battinelli and Summers is independent under the applicable NASDAQ rules and regulations and is a “non-employee director” as defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Nominating and Corporate Governance Committee The Nominating and Corporate Governance Committee’s responsibilities include: ● ● ● identifying individuals qualified to become board members; recommending to our board the persons to be nominated for election as directors and to each of the board’s committees; and overseeing an annual evaluation of the board. The members of our Nominating and Corporate Governance Committee are Messrs. Duitch, Battinelli and Summers, and Mr. Duitch serves as the interim chairperson of the committee. Our board has determined that each of Messrs. Duitch, Battinelli and Summers is independent under the applicable NASDAQ rules and regulations. The Nominating and Corporate Governance Committee was established effective February 15, 2017 (i.e., when our common stock became listed on The NASDAQ Capital Market). 30 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 Annual 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. 31 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. Section 16(a) Beneficial Ownership Reporting Compliance 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 its most recent fiscal year ended December 31, 2019, its executive officers, directors and greater than 10% stockholders complied with the filing requirements under Section 16(a), except that (i) Ronald Fisher filed a Form 4 late in connection with (a) the forfeiture of shares of common stock with respect to an applicable milestone not being satisfied, and (b) the receipt of shares of common stock based on an applicable milestone being achieved, and (ii) John Rice filed a Form 4 late relating to his acquisition of two stock options as compensation in his capacity as an officer. 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. The following table sets forth compensation for services rendered in all capacities to the Company: (i) for each person who served as the Company’s Chief Executive 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 with the Company on December 31, 2019 (the foregoing executives are herein collectively referred to as the “named executive officers”). 32 Name and Principal Position John Rice - President, Chief Executive Officer (Principal Executive Officer) and Director (Chairman of the Board) Ronald Fisher - Vice President of Business Development Darren Beckett – Chief Technology Officer (1) Actual amounts paid or accrued.

Equity Awards We offer stock options and stock awards to certain of our employees, including our executive officers, as the long-term incentive component of our compensation program.

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. We sometimes also offer stock options 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. Stock options 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 have elected to match 100% of each participant’s contribution up to 3% of salary, and 50% of the next 2% of salary contributed. We may also elect, on an annual basis, to make a discretionary contribution to the plan, but have not done so to date. Our 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. 38 2011 Equity Incentive Plan On August 23, 2019, our Board of Directors terminated the 2011 Equity Incentive Plan. 2013 Equity Incentive 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 Subject to the provisions of the 2013 Plan relating to adjustments upon changes in common stock, an aggregate of 240,000 shares of common stock are currently subject to outstanding awards under the 2013 Plan or future awards 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. 39 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. 40 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. For example, if an Option is for 1,000 shares for $20.00 per share and there is a 2-for-1 stock split, the Option would be adjusted to be exercisable for 2,000 shares at $10.00 per share. 41 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. As of March 20, 2020, there were 161,628 shares previously issued or subject to outstanding awards under the 2013 Plan and 27,486 shares were available for future issuance under the 2013 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, each non-employee director received annual compensation of $27,000 and 5,000 shares of restricted common stock, which vested ratably each quarter. In addition, the Chairperson of the Audit Committee received a $5,000 annual retainer in cash. 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 periodically evaluates our director compensation program and determines whether any changes should be recommended to the Board. In that regard, while the foregoing director compensation program will continue for 2020, in February 2020, our directors agreed to defer the payment of their cash compensation for the first two quarters of 2020 as a cash saving measure, and to defer the issuance of shares of common stock. The following table sets forth certain information concerning the compensation paid to non-employee directors in 2019 for their services as directors of the Company. The compensation of Mr. Rice, who serves as a director and serves as our President and Chief Executive Officer, is described in the Summary Compensation Table of Executive Officers. Our non-employee directors do not receive fringe or other benefits.

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 20, 2020 (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 1,627,182 shares of our common stock outstanding on March 20, 2020. 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 24, 2020 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. Unless otherwise stated, the address of each 5% or greater beneficial holder is c/o Sigma Labs, Inc., 3900 Paseo del Sol, Santa Fe, New Mexico 87507. 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.

The 2013 Equity Incentive Plan was approved by holders of at least a majority of the issued and outstanding shares of common stock of the Company on October 10, 2013. Pursuant to the 2013 Equity Incentive Plan, the Company is authorized to grant “incentive stock options” and “non-qualified stock options”, grant or sell common stock subject to restrictions or without restrictions, and grant stock appreciation rights to employees, officers, directors, consultants and advisers of the Company and its subsidiaries. Incentive stock options granted under the 2013 Equity Incentive Plan are intended to qualify as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code (the “Code”). Non-qualified stock options granted under the 2013 Equity Incentive Plan are not intended to qualify as incentive stock options under the Code. As of December 31, 2019, the Company issued an aggregate of 50,886 shares of the Company’s common stock, as well as options to purchase up to 180,903 shares of the Company’s common stock, some of which are subject to vesting restrictions, pursuant to the Company’s 2013 Equity Incentive Plan.

In connection with our January 27, 2020 private placement of equity securities, we issued Dawson James a warrant to purchase up to 17,004 shares of common stock at an initial exercise price of $11.30.

ITEM 13.

Transactions with Directors and Officers On August 8, 2017, we engaged Garofalo & Associates, LLC, a limited liability company owned and controlled by Mr. Garofalo, a former director of the Company, to provide services to the Company as corporate development consultant and financial advisor. Under the engagement letter agreement, Garofalo & Associates, LLC, is entitled to receive in consideration for its services a monthly retainer of $3,000 in cash during the term of the engagement (the engagement may be terminated by both parties upon 30 days’ written notice), and (i) 10,500 shares of common stock of the Company upon the closing of an acquisition by the Company of all or substantially all of the equity or assets (or a controlling interest therein) (the “Closing”) with respect to a specified entity (the value of such shares would have been $238,350 if such shares would have been issued on August 8, 2017, based on a closing price per share of $22.70 on such date), and (ii) 7,500 shares of common stock of the Company upon the Closing with respect to at least one of two other specified entities (the value of such shares would have been $170,250 if such shares would have been issued on August 8, 2017, based on a closing price per share of $22.70 on such date).

However, the decision to provide any such bonuses and the amount and terms of any such bonuses will be in the sole discretion of the Board of Directors. We have entered into an “at will” employment agreement, effective as of July 1, 2019, with Frank Orzechowski under which he was engaged to serve as our Chief Financial Officer, Treasurer, Principal Accounting Officer and Corporate Secretary of the Company.

Opinion on the Financial Statements We have audited the accompanying balance sheets of Sigma Labs, Inc. (the Company) as of December 31, 2019 and 2018, and the related statements of operations, stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2019, 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. /s/ Haynie & Company Haynie & Company Salt Lake City, Utah March 24, 2020 We have served as the Company’s auditor since 2018.

NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2019 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, 2019 and 2018 and for the periods then ended have been made. 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 2019, the Company relied on both public and private offerings to finance the commencement of commercialization by entering test and evaluation programs with large potential customers, both end-users and OEMs. On March 15, 2019, the Company closed a public offering of equity securities resulting in net proceeds of approximately $1,679,230, after deducting placement agent commissions and other offering expenses payable by the Company. In May 2019, the Company closed a private placement of equity securities resulting in net proceeds of approximately $515,000, after deducting placement agent commissions and other offering expenses payable by the Company. In August 2019, the Company closed a public offering of equity securities resulting in net proceeds of approximately $1,971,000, after deducting placement agent commissions and other offering expenses payable by the Company. In September 2019, Aegis Capital Corp. partially exercised its over-allotment option granted by the Company in the foregoing August 2019 public offering resulting in net proceeds of $148,800 after deducting placement agent commissions. The transition from 2018 and 2019 led into 2020 such that the continuing operations of the Company are no longer dependent upon financing the cost of product development in the absence of revenues, but rather now 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, thus attracting investor support for continuing investment even as the revenues begin the reduction of the company’s dependence on capital raises over time. In January 2020, the Company closed two private placements of equity securities resulting in net proceeds of approximately $1,711,124 after deducting placement agent commissions and other offering expenses payable by the Company. As a result, the Company currently has sufficient cash and working capital to fund operations through the end of the first quarter of 2020 and is anticipating that contracts may be closed during fiscal 2020 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 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, 2019 and 2018, the Company had the following common shares underlying these instruments: Warrants Stock Options Convertible Note Payable Total Underlying Common Shares Year Ended December 31, 2019 2018 363,727 180,903 2,500 547,130 305,060 82,627 2,500 390,187 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. F-7 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, 2019 and 2018 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, 2019 and 2018, the Company recognized no interest and penalties. All tax years starting with 2016 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, 2019 or 2018. F-8 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. $50,255 of dental patents were written off in January of 2018, and $23,909 of patents related to PrintRite3D® Contour were written off in December of 2019. 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. 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. F-9 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, 2019 and 2018 were $647,994 and $493,410, respectively. NOTE 2 - Notes Receivable On May 1, 2017, the Company made a loan in the principal amount of $250,000 to Jaguar Precision Machine, LLC, a New Mexico limited liability company (“Jaguar”), pursuant to a Secured Convertible Promissory Note dated May 1, 2017 delivered by Jaguar to the Company.

NOTE 5 – 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 2019, the Company wrote off $23,909 of patent costs related to PrintRite3D® Contour, which application was allowed to lapse. In addition, $91,863 of costs related to patents issued to us during 2019 were reclassified from provisional patent application to patent status and began to be amortized as of the date of issue. The following is a summary of definite-life intangible assets less accumulated amortization as of December 31, 2019 and 2018, respectively: Provisional Patent Applications Patents Less: Accumulated Amortization Net Intangible Assets Year Ended December 31, 2019 2018 448,714 $ 138,936 (18,309) 569,341 $ 366,353 47,073 (8,448) 404,978 $ $ Amortization expense on intangible assets was $9,861 and $2,094 for the years ended December 31, 2019 and 2018, respectively.

As of December 31, 2019, an aggregate of 8,211 shares of common stock were reserved for issuance under the 2013 Plan. During 2019, the Company granted a total of 100,326 options to 22 employees and 2 consultants with vesting periods ranging from immediately/upon issue to 4 years beginning January 1, 2019. In 2019, 38,143 options vested and $494,240 of compensation cost was recognized during the year. As of December 31, 2019, there were options to purchase 180,903 shares issued and outstanding under the 2013 Plan. Of this amount, there are vested options exercisable for 88,163 shares of common stock. No options were exercised during the year ended December 31, 2019. During 2018, the Company granted a total of 53,433 options to 18 employees and 1 consultant with vesting periods ranging from immediately/upon issue to 4 years beginning February 2018. In 2018, 41,549 options vested and $868,015 of compensation cost was recognized during the year. As of December 31, 2018, there were options to purchase 82,627 shares issued and outstanding under the 2013 Plan. Of this amount, there are vested options exercisable for 50,098 shares of common stock. No options were exercised during the year ended December 31, 2018. The Company generally grants stock options to employees 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 four years of service and expire ten 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 share-based compensation expense included in the statements of operations for the years ended December 31, 2019 and 2018 is $797,238, of which $494,240 is related to stock options, and $1,145,530, of which $868,015 is related to stock options, respectively. There was no capitalized share-based compensation cost as of December 31, 2019 and 2018, and there were no recognized tax benefits during the years ended December 31, 2019 and 2018. To estimate the value of an award, the Company uses the Black-Scholes option-pricing model. This model requires inputs such as expected life, expected volatility and risk-free interest rate. The forfeiture rate also impacts the amount of aggregate compensation. These inputs are subjective and generally require significant analysis and judgment to develop. While estimates of expected life, volatility and forfeiture rate are derived primarily from the Company’s historical data, the risk-free rate is based on the yield available on U.S. Treasury constant maturity rates with similar terms to the expected term of the stock option awards. The fair value of share-based awards was estimated using the Black- Scholes model with the following weighted-average assumptions for the years ended December 31, 2019 and 2018: F-15 Assumptions: Dividend yield Risk-free interest rate Expected volatility Expected life (in years) Option activity for the year ended December 31, 2019 and 2018 was as follows: 2019 0.00 1.42-2.53% 105.2-112.1% 5-10 2018 0.00 2.68-3.10% 104.9-137.3% 5-10 Options outstanding at December 31, 2017 Granted Exercised Forfeited or cancelled Options outstanding at December 31, 2018 Granted Exercised Forfeited or cancelled Options outstanding at December 31, 2019 Options expected to vest in the future as of December 31, 2019 Options exercisable at December 31, 2019 Options vested, exercisable, and options expected to vest at December 31, 2019 Weighted Average Exercise Price ($) Weighted Average Remaining Contractual Life (Yrs.)

Six of the 2019 option grants have an exercise price currently below $9.82. At December 31, 2019, there was $793,796 of unrecognized share-based compensation expense related to unvested share options with a weighted average remaining recognition period of 4.88 years. Warrants At December 31, 2019, the Company had outstanding warrants to purchase a total of 363,727 shares of common stock; 162,150 warrants at an exercise price of $40.00 per share, which if not exercised, will expire on February 21, 2022, 89,000 warrants at an exercise price of $14.70 per share, which if not exercised, will expire on October 07, 2023, 46,887 warrants at an exercise price of $10.80 per share, which if not exercised, will expire on June 26, 2023, 42,024 warrants at an exercise price of $16.10 per share, which if not exercised, will expire on March 15, 2024, 20,000 warrants with an exercise price of $15.60 per share, which if not exercised, will expire on May 7, 2024, 2,000 warrants with an exercise price of $17.50 per share, which if not exercised, will expire on May 7, 2024, and 1,666 warrants with an exercise price of $0.10, which if not exercised, will expire on November 18, 2022. Warrant activity for the year ended December 31, 2019 and 2018 was as follows: Warrants outstanding at December 31, 2017 Granted Exercised Forfeited or cancelled Options outstanding at December 31, 2018 Granted Exercised Forfeited or cancelled Warrants outstanding at December 31, 2019 Weighted Average Exercise Price ($) Warrants Weighted Average Remaining Contractual Life (Yrs.) 164,550 160,700 (20,190) - 305,060 65,690 (7,023) - 363,727 39.70 13.00 11.90 - 27.50 15.60 10.80 - 25.60 4.11 4.64 - - 3.86 4.39 - - 3.12 F-16 NOTE 8 – 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, 2016 through 2018. The Company has available at December 31, 2019, unused operating loss carryforwards of approximately $14,469,000, which may be applied against future taxable income and which expire in various years through 2039. 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 $3,037,800 and $2,123,700 at December 31, 2019 and 2018, 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 Net deferred tax asset 2019 2018 $ $ 3,038,600 $ (800) (3,037,800) - $ 2,105,600 18,100 (2,123,700) - The reconciliation of the provision for income taxes computed at the U.S. federal statutory tax rate (21%) to the Company’s effective tax rate for the years ended December 31, 2019 and 2018 is as follows: Book Loss Depreciation Meals & Entertainment Stock Compensation Loss on Asset Disposal Change in valuation allowance Provision for Income Taxes $ $ 2019 2018 (1,327,400) $ 19,000 167,420 1,900 - 1,139,080 - $ (1,170,600) 13,400 2,600 242,730 7,714 904,156 - F-17 NOTE 9 – Loss Per Share The following data show the amounts used in computing loss per share and the effect on income and the weighted average number of shares of dilutive potential common stock for the periods ended December 31, 2019 and 2018: Loss from continuing Operations available to Common stockholders (numerator) Weighted average number of common shares Outstanding used in loss per share during the Period (denominator) Year Ended December 31 2019 2018 $ (6,320,849) $ (5,574,163) 1,176,278 689,805 Dilutive loss per share was not presented as the Company’s outstanding warrants, stock options and note conversion features common equivalent shares for the periods presented would have had an anti-dilutive effect. At December 31, 2019, the Company had outstanding 363,727 warrants which could be converted to 363,727 shares of common stock, a $50,000 note payable convertible into 2,500 shares of common stock, and 180,903 stock options exercisable for 180,903 shares of common stock resulting in a potential total additional 475,130 common stock shares outstanding in the future. At December 31, 2018, the Company had outstanding 305,050 warrants which could be converted to 305,060 shares of common stock, a $50,000 note payable convertible into 2,500 shares of common stock, and 82,627 stock options exercisable for 82,627 shares of common stock resulting in a potential total additional 390,187 common stock shares outstanding in the future. NOTE 9 – Commitments and Contingencies Operating Leases – The Company leases office and laboratory space under operating leases. Expense relating to these operating leases was $73,255 and $70,187 for the years ended December 31, 2019 and 2018, respectively. The future minimum lease payments required under non-cancellable operating leases at December 31, 2019 were $28,305. The future minimum lease payments are due during the year 2020. NOTE 10 – Concentrations Revenues – During the years ended December 31, 2019 and 2018, the Company had the following significant customers who accounted for more than 10% each of the Company’s revenue in at least one of the periods presented. The change in the composition of customers between the two years resulted primarily from the change of focus from sales to R&D customers to Proof of Concept sales to customers preparing to initiate commercial production.

The Joint Venture was not consolidated, but rather was accounted for on the equity method of recording investments. There were no operating activities during the fiscal 2017 and net operations resulted in a loss on the investment of $105 in fiscal 2016. The Company and Arete agreed in 2017 to terminate the Joint Venture and are in the process of paying final costs. The remaining cash asset of the company will be distributed to the former partners in 2020. NOTE 12 - Defined Contribution Plan In 2014, the Company adopted a qualified 401(K) plan (“the Plan”), in which all employees over the age of 21 may participate. The Company has elected to match 100% of each participant’s contribution up to 3% of salary, and 50% of the next 2% of salary contributed. The costs of matching contributions were $45,080 in 2019 and $51,415 in 2018. NOTE 13 – Related Party Transactions On June 17, 2019, our Former Chief Financial Officer, Nannette Toups submitted notice to the Company of her resignation effective August 15, 2019.

NOTE 14 – Subsequent Events 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 Series D Convertible Preferred Stock (the “Series D Preferred Stock”), warrants to purchase 779,600 shares of the Company’s Common Stock (the “Common Warrants”) and warrants to purchase 6,156 shares of the Series D Preferred Stock (the “Preferred Warrants”) for a total gross purchase price of $1,600,000. The Series D Preferred Stock is initially convertible into 164,000 shares of Common Stock, the Preferred Warrants have an initial exercise price of $975.00 per share, and the Common Warrants have an initial exercise price of $10.00 per share.

Total net proceeds from the private placements were approximately $1,711,124, after deducting placement commissions and other offering expenses payable by the Company. On January 31, 2020, the Company paid off its Secured Convertible Promissory Note in full in the amount of $56,458, including accrued interest of $1,458 and a late fee penalty of $5,000. Effective February 27, 2020, our Amended and Restated Articles of Incorporation were amended pursuant to a Certificate of Change Pursuant to Nevada Revised Statutes 78.209 (the “Certificate of Change”) filed with the Nevada Secretary of State. The Certificate of Change provided for both 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”). As a result of the Reverse Stock Split, the number of issued and outstanding shares of our common stock decreased from 14,500,823 pre-Reverse Stock Split shares to 1,450,082 post-Reverse Stock Split shares (after adjustment for any fractional shares). Pursuant to the Share Decrease, the number of authorized shares of our common stock decreased from 22,500,000 to 2,500,000 shares of common stock, $0.001 par value per share. F-19 DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934 Exhibit 4.11 Sigma Labs, Inc. (“Sigma,” “we,” “our,” and “us”) has two classes of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended: (1) our common stock, par value $0.001 per share (the “common stock”), and (2) warrants to purchase common stock at an exercise price of $40.00 per share (the “Public Warrants”). 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 on April 1, 2019, (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-Q on November 14, 2017, (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 4.11 is a part. We encourage you to read the Certificate 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 2,250,000 shares of common stock, $0.001 par value per share, of which 1,627,182 shares were outstanding as of March 20, 2020. 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, 880 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. 1 Public Warrants The Public Warrants are exercisable at an exercise price of $40.00 per share, subject to certain adjustments. The Public Warrants expire on February 21, 2022. Each Public Warrant will have a cashless exercise right in the event that shares of common stock underlying such Warrants are not covered by an effective registration statement. As of December 31, 2019, we had 162,150 Public Warrants outstanding. 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 and 50,000 shares of common stock issued upon conversion of such shares are currently beneficially owned by an affiliate of a selling stockholder. 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: the Series D Preferred Stock and the Series E Preferred Stock. As of the date of this Form 10-K, 880 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 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 initially is $10.00 (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. 2 The Certificate of Designations contains a prohibition on the issuance of any shares of Common Stock upon conversion of the Series D Preferred Shares in excess of the amount set forth in NASDAQ Listing Rule 5635(d) (20% or more of the outstanding shares of common stock) until the Company obtains shareholder approval for issuance of shares of Common Stock in excess of such amount. In the Institutional SPA, the Company has agreed to promptly obtain such shareholder approval and amend its article of incorporation and/or effect a reverse split in order to have sufficient shares of Common Stock available to allow the holders of the Series D Preferred Shares to convert in full the Series D Preferred Shares and exercise in full the Institutional Common Warrants. 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. Transfer Agent 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; 3 ● ● ● ● ● ● ● 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 and Public Warrants are currently traded on the NASDAQ Capital Market under the symbols “SGLB” and “SGLBW” respectively. 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. 4 Exhibit 10.15 December 2, 2019 Mark Ruport 1729 Wood Avenue Colorado Springs, CO 80907 Re: Terms of At-Will Employment Dear Mr. Ruport, This letter confirms the principal terms of our agreement, as set forth below, with respect to your at-will employment (“Employment”) by Sigma Labs, Inc.
