PART I

Item 1. Business.

Our Corporate History

Information Systems Associates, Inc. (“ISA”) was incorporated in Florida on May 31, 1994. Our original business operations consisted of consulting services for asset management of large corporate data centers and the development and licensing of information technology (“IT”) asset management software. In late 2014, ISA entered negotiations with Duos Technologies, Inc. (“duostech™”) for the purposes of executing a merger between the two organizations (also known as a “reverse triangular merger”). Incorporated under the laws of Florida on November 30, 1990, duostech™ operated in various industry segments, specializing in the design, development and deployment of proprietary technology applications and turn-key engineered systems. This transaction was completed on April 1, 2015, whereby duostech™ became a wholly owned subsidiary of ISA. After the merger was completed, ISA changed its corporate name to Duos Technologies Group, Inc. (together with its subsidiaries, “Duos,” “we,” “us” or the “Company”). The Company, based in Jacksonville, Florida, oversees its wholly owned subsidiary, duostech™ and employs approximately 7571 people and is a technology company which designs, develops, deploys and operates intelligent technology solutions with a focus on software applications and artificial intelligence (“AI”). The companyCompany has a strong portfolio of intellectual property. The Company’s headquarters are located at 7660 Centurion Parkway, Suite 100, Jacksonville, Florida 32256 and main telephone number is (904) 296-2807.

Overview

The Company, operating under its brand name duostech, develops and deploys technology systems with focus on inspecting and evaluating moving vehicles. Its technology focus is within the Vision Technology market sector and, more specifically, the Machine Vision subsector. Machine Vision companies provide imaging-based automatic inspection and analysis for process control for industry with potential expansion into other markets. Duos has developed key technologies over the past several years in software, industry specific hardware and artificial intelligence and has demonstrated industrial strength usability of its systems supporting rail, logistics and intermodal businesses that streamline operations, improve safety and reduce costs. Our team includes engineering subject matter expertise in hardware, software, and information technology as well as industry specific applications of artificial intelligence also referred to as Expert Artificial Intelligence. We also have specific industry experts in the rail industry on staff and as consultants in the rail industry.consultants.

Duos is currently developing industry solutions for its target markets which will address rail, trucking, aviation and other vehicle-based processes. Duos’ initial offering, the Railcar Inspection Portal (RIP), provides both freight and transit railroad customers and select government agencies the ability to conduct fully automatedremote railcar inspections of trains while they are moving at full speed. The RIP utilizes a variety of sophisticated optical, laser and speed sensors to scan each passing railcar to create a high-resolution image-set of the top, sides and undercarriage. These images are then processed with our edge data center using artificial intelligence (AI) algorithms to identify safety and security defects on each railcar. The algorithms are developed in conjunction with industrial application experts, in this case resident Railcar Mechanical Engineers, to provide specific guidance in the analysis (“human in the loop”). Within minutesseconds of the railcar passing through the RIP, a detailed report is sent to the customer where they are able to take action on identified issues. This solution has the potential to transform the railroad industry byimmediately increasing safety, improving efficiency and reducing costs. The Company has already deployed this system with several Class 1 railroads and anticipates an increased demand from transit and other railroad customers along with selected government agencies that operate and/or manage rail traffic. The Company has deployed RIPs in Canada, Mexico and the United States and anticipates expanding this solution into Europe, Asia and the Middle East in coming years.

The Company has also developed the Automated Logistics Information System (ALIS) which automates gatehouse operations where transport trucks enter and exit large logistics and intermodal facilities. This solution incorporates a similar set of sensors, data processing and artificial intelligence to streamline the customer’s logistics transactions and tracking and can also automate the security and safety inspection if called for. The Company has already deployed this system with one large North American retailer and anticipates increased demand from other large retailers, railroad intermodal operators and select government agencies that manage logistics and border crossing points. The Company is evaluating other solutions for moving vehicles including aircraft, which could provide similar benefits in terms of safety and efficiency for required inspections as part of an operations process.

We have developed two proprietary solutions that operate our software and artificial intelligence. centraco^® is an Enterprise Information Management Software platform that consolidates data and events from multiple sources into a unified and distributive user interface. Customized to the end user’s Concept of Operations (CONOPS), it provides improved situational awareness and data visualization for operational objectives compared to traditional manual inspections. truevue360^™ is our fully integrated platform that we utilize to develop and deploy Artificial Intelligence (AI) algorithms, including Machine Learning, Computer Vision, Object Detection and Deep Neural Network-based processing for real-time applications.

These same Artificial Intelligence applications have begun to open up other opportunities for the Company to provide revenue producing solutions with potentially high market adoption.

In 2021, the Company ended support of its IT Asset Management (ITAM) solution which cataloged results for data center asset inventory and audit services. We are currently evaluating using our current operations experience within “edge data centers” (as deployed for our Railcar Inspection Portal) to drive additional revenues within other markets requiring this type of solution although no specific offering has been developed at this time.

In the last quarter of 2022, the Company elected not to renew a support contract for its Integrated Correctional Automation System (iCAS) for one customer. The Company is currently lookingsubsequently sold its iCAS assets to sella buyer during the assets related to that business but due to the limited naturesecond quarter of this business, any impact is not expected to be material.2023 for $165,000 via a convertible note.

The year 20222023 ushered in a new phase in the Company’s development. Although we continue to see an extension of challenges faced in 2021,2022, we also see positive changes and opportunities for our business that will be discussed in greater detail later in this report.herein. They include:

Railcar Inspection Portal (rip®)

Federal regulations require each railcar/train to be inspected for mechanical defects prior to leaving a rail yard. Founded in 1934, the Association of American Railroads (AAR) is responsible for setting the standards for the safety and productivity of the U.S./North American freight rail industry, and by extension, has established the inspection parameters for the rail industry’s rolling stock. Also known as the “Why Made” codes, the AAR established approximately 110 inspection points under its guidelines for mechanical inspections.

Under current practice, inspections are conducted manually, a very labor intensive and inefficient process that only covers a select number of inspection points and can take several hours per train. We believe our Railcar Inspection Portal has the potential to reduce this inspection to minutes while the train is moving at speed, improving safety, reducing dwell time and optimizing maintenance.

Our system combines high-definition image and data capture technologies with our AI-based analytics applications that are typically installed on active tracks located between two rail yards. We inspect railcars traveling through our inspection portal at speeds of up to 70 mph and report mechanical anomalies detected by our system to the inbound train yard, well ahead of the train entering the yard.

Currently, three Class 1 railroads and several transit and international railroads use our rip® technology with one of those railroads broadly deploying the technology across its network.

The Company continues to expand its detection capabilities through the development and integration of additional sensor technologies to include laser, infrared, thermal, sound and x-ray to process AI-based analytics of inspection points. As of early 2023,Currently the Company has a high-reliability catalog of over 3048 artificial intelligence algorithms which can be integrated into the RIP to enhance mechanical anomalies detections. These detections support railroads in the active maintenance and overall safety of their railcar fleet and networks.

Markets

We believe the opportunity for our Railcar Inspection Portal business is substantial and continues to be our number one priority. We are currently engaged with the RIP solution with three of seven Class 1 railroad operators with 13 systems already deployed across the North American rail network. Because of our early leadership position, we have been able to accumulate experience and intellectual property that we believe would be time consumingtime-consuming and expensive for a new competitor to replicate. Furthermore, we believe we have the ability to upgrade and scale our solutions with additional technologies in the future. We believe that the current market for our technologies is substantial. At the same time, we recognize that the technology life cycle is fast and evolving. Potential competitors could move into this sector, and it is possible that some Class 1 railroads could develop their own solutions that limit our total addressable market.

In late 2022, the Company announced it will pursue a subscription platform for the Railcar Inspection Portals (“RIPs”).RIPs. Under this new model, the Company will build, own and operate its RIP product and offer the data access for each portal to potential customers. This expansion of the RIP offering would potentially open up the addressable market to other railroads, railcar owners, and car lessors. This shift increases the pool of potential customers by lowering the entry point for the RIP and would reshape the Company’s working capital needs to invest in the construction of a RIP ahead of customer revenue inflows. The Company continues to explore this expansion on the long-term effects it may have on future cash flows.

Another market we are pursuing as our second priority is using our Automated Logistics and Information Systems solution (alis™). Potential customers include commercial retail logistics and intermodal operators, Class 1 rail intermodal operators that are moving large amounts of automobiles, and U.S. Government agencies such as the Department of Defense and the Department of Homeland Security. Today, we currently have 20 production systems in use, but we believe the greenfield opportunity here to be substantial. We have identified over 900 lanes of traffic within nearly 300 facilities as potential business opportunities in the near-term.

Currently, we are focused on the North American market, but plan to expand globally in the future with interest from Europe, Asia and the Middle East.

Patents and Trademarks

The Company holds a number of patents and trademarks for our technology solutions. We protect our intellectual property rights by relying on federal, state, and common law rights, as well as contractual restrictions. We control access to our proprietary technology by entering into confidentiality and invention assignment agreements with all of our employees and contractors, and confidentiality agreements with third parties. We also actively engage in monitoring activities with respect to infringing uses of our intellectual property by third parties.

Specific Areas of Competition

One of our primary commercial goals is to develop innovative technology solutions and target potential “greenfield” market spaces in order to maximize our business footprint and give us the ability to help define the market parameters for the future.

Other companies that participate in the visual and optical (laser) based railcar inspection systems market include Wabtec (Beena Vision), KLD Labs, WID, IEM, and Camlin Rail. Some Class 1 railroads have stated that they are developing “in-house” solutions. We believe that Duos has a significant competitive advantage in that we have multiple years of deployment experience, have access to millions of images where our RIP has performed scans with AI analysis and in-house industry expertise to train our systems and make identification of common problems more automated.

Our Automated Logistics Information System (ALIS) also represents an opportunity to expand into a mature market that we believe has a significant technology gap.  While most facilities, such as distribution centers, that process commercial trucks in and out have sophisticated software management applications for logistics control, they have most often not implemented an advanced gatehouse automation solution. Historically, this category was referred to as “Automated Gate Systems” or AGS.  The purpose of AGS technology is to streamline entry in to and exit out of facilities.  The marketplace for this was mostly seaports and intermodal transfer facilities and was relatively expensive technology to deploy. 

Our Growth Strategy

Vision

The Company designs, develops, deploys and operates intelligent technology solutions for inspecting and evaluating moving objects. Its technology application focus is within the rail and intermodal markets which offers imaging-based automatic inspection and analysis for process control for industry with potential expansion into other markets.

Objectives

Organic Growth

Our organic growth strategy is to continue our focus and prioritization in the rail, logistics and intermodal market space. In this regard, the Company has made significant changes in the senior management team to include a new Chief Executive Officer, who joined the Company in 2022September 2020 and has years of experience successfully leading start-up and turn-around companies. In addition, a key account executive from one of duos’Duos’ competitors has joined the executive team during late 2022 as the Senior Vice President of Sales & Marketing to support the continued revenue growth of the business and brings with him over 20 years ofbringing significant sales experience focused inaround the rail market. In the third quarter of 2023, the Company also brought on a new Chief Commercial Officer bringing significant experience from the sales and operations aspects of the intermodal and power industries. In 2021, the Company also hired a new Chief Technology Officer bringing 25 years of experience in designing and delivering on value driven technologies. Our new CTO has already led the team through instrumental changes to its approach to software and artificial intelligence development. The team also saw a change in CFO in late 2022 who bringswith the new CFO bringing significant experience in growth for asset-intensive businesses which aligns with the subscription format the Company will expand into.

The new leadership team’s focus is to improve operational and technical execution which will in turn enable the commercial side of the business to expand RIP and ALIS delivery into existing and new customers. Even though supply chain issues are expected to continue through 2023,in 2024, the Company’s primary customers have indicated readiness to order more equipment and services based upon the Company’s current performance and the new subscription offerings expands the universe of potential customers.

Additionally, the CEO has directed that the Company make continual engineering and software upgrades to the RIP to meet anticipated Federal Railroad Association (FRA) and Association of American Railroad (AAR) standards.

Manufacturing and Assembly

The Company designs and develops technology solutions using a combination of in-house fabrication, commercial off-the-shelf technology, and outsourced manufacturing. On-site installations are performed using a combination of in-house project managers and engineers and using third-party sub-contractors as needed. Throughout the process of design, develop, deploy and operate, the Company maintains responsibility for all aspects. Our internal manufacturing operations consist primarily of materials procurement, assembly, testing and quality control by our engineers. If not manufactured internally, we use third-party manufacturing partners to produce our hardware related components and hardware products and we most often complete final assembly, testing and quality control processes for these components and products. Our manufacturing processes are based on standardization of components across product types, centralization of assembly and distribution centers, and a “build-to-order” methodology in which products generally are built only after customers have placed firm orders. For most of our hardware products, we have existing alternate sources of supply.

For 20232024 and possibly beyond, we expect to face significant challenges with macro-economic impacts, specifically inflation and supply chain disruption. Although these started to be identified in late 2021, we believe they continue to manifest themselves in ways that could challenge our business growth in the future. Specifically, the ability to source key components and certain implementation services will dictate just how quickly the Company can meet desired installation deadlines. In the industries in which we operate, the time from concept to contract can be substantial. Although we are now adapting to these challenges, previous bids that have been submitted could be challenging to execute within the financial framework and execution times originally envisaged. We continue to have dialogue with our customers regarding potential price increases and implementation delays, but we may suffer some economic impacts as a result of this. Revenue recognition could be delayed as a result of these factors and profitability could be impacted due to higher costs for materials and other services. The Company will continue to monitor the situation and update shareholders as the situation unfolds.

Research and Development

The Company’s R&D and software development teams design and develop all systems and software applications with a combination of full-time in-house software engineers and outside contractors. Internal development allows us to maintain technical control over the design and development of our products. Rapid technological advances in hardware and software development, evolving standards in computer hardware and software technology, and changing customer requirements characterize the markets in which we compete. We plan to continue to dedicate significant resources to research and development efforts, including software development, to maintain and improve our current product and services offerings.

Government Regulations

The Company has worked with various agencies of the federal government for more than 10-years10 years including the Department of Homeland Security (“DHS”). When our solutions have been deployed into these agencies, they meet specific requirements for certification, safety and security that are stipulated in requirements and contract documents. The Company is currently competing for other government related work and strictly follows the rules and regulations outlined in the Federal Acquisition Regulations.

The Company’s primary customers are all governed by regulations related to the safe and effective transportation of goods and passengers, primarily by rail, but in future scenarios by air, road and sea. While changes in the regulatory environment could impact the Company in future years, we believe any changes will be overall positive for the Company. We continuously review potential changes in the regulatory environment and maintain contact with key personnel at certain agencies including the Federal Railroad Administration (FRA), the Transportation Safety AgencySecurity Administration (TSA) as well as the DHS previously mentioned. We expect to develop similar relationships with governmental agencies in target marketmarkets both in the US and internationally. At this time, we believe our offerings are complementary to the current and evolving standards and that we will adapt to any new regulations as they are promulgated.

Employees

We have a current staff of 7571 employees, of which 6766 are full-time, the majority of which work in the Jacksonville area, none of which are subject to a collective bargaining agreement. We have not experienced any work stoppages and we consider our relationship with our employees to be good.

Item 1A. Risk Factors.

Risks Related to Our Company and Business

The nature of the technology management platforms utilized by us are complex and highly integrated, and if we fail to successfully manage releases or integrate new solutions, it could harm our revenues, operating income, and reputation.

The technology platforms developed and designed by us accommodate integrated applications that include our own developed technology and third-party technology, thereby substantially increasing their functionality.

Due to this complexity and the condensed development cycles under which we operate, we may experience errors in our software, corruption or loss of our data, or unexpected performance issues from time to time. For example, our solutions may face interoperability difficulties with software operating systems or programs being used by our customers, or new releases, upgrades, fixes or the integration of acquired technologies may have unanticipated consequences on the operation and performance of our other solutions. If we encounter integration challenges or discover errors in our solutions late in our development cycle, it may cause us to delay our launch dates. Any major integration or interoperability issues or launch delays could have a material adverse effect on our revenues, operating income and reputation.

We face risks as a result of the coronavirus (COVID-19 pandemic) lingering effects which could significantly disrupt our research and development, operations, sales, and financial results.

Our business has been adversely impacted by the effects of the COVID-19 pandemic. In addition to global macroeconomic effects, the COVID-19 pandemic and related adverse public health developments caused disruption and/or delays to our operations and sales activities. Our third-party manufacturers and our customers were disrupted by worker absenteeism, quarantines and restrictions on employees’ ability to work, office and factory closures, disruptions to ports and other shipping infrastructure, border closures, or other travel or health-related restrictions. Depending on the magnitude of such effects on our activities or the operations of our third-party manufacturers and third-party distributors, the supply of our products, in some cases, continue to be delayed, which could continue to adversely affect our business, operations and customer relationships. In addition, the pandemic or other disease outbreak have had and may continue to have over the longer term a material adverse effect on the economies and financial markets of many countries, resulting in an economic downturn that will affect demand for our products and services and impact our operating results. There can be no assurance that any decrease in sales resulting from the pandemic slowdown will be offset by increased sales in subsequent periods. Although the magnitude of the impact of the COVID-19 outbreak on our business and operations remains uncertain, the continued spread of COVID-19 and the related public health measures and travel and business restrictions may adversely impact our business, financial condition, operating results and cash flows. In addition, we have experienced and may in the future experience disruptions to our business operations resulting from quarantines, self-isolations, or other restrictions on the ability of our employees to perform their jobs that may impact our ability to develop and design our products and services in a timely manner or meet required milestones or customer commitments.

We may be adversely affected by the effects of inflation and supply chain disruption

Our business operates in an environment of long bid to contract award cycles. Our customer’s bid requirements are such that firm pricing is expected on much or all of our proposalproposals and as such we must commit to certain commercial terms and conditions such as pricing. In addition, the Company hires employees and contractors to perform most (if not all) of the work required to complete a contract. We are beginning to experience the impacts of inflation upon previously forecasted costs including employees that require higher salaries, contractors demanding higher prices for jobs and higher costs for materials necessary to complete contracts. While we endeavor to charge additional costs to our customers, in some cases this may not be possible contractually and as a result our profitability may suffer as a result. Although we anticipate these effects to be mitigated in the long term, we cannot be assured that this will be possible in all or any instances and as such our revenue, profitability and growth prospects may suffer as a result of this.

Current supply chain issues continue to extend deadlines for shipment of key components used in our technology systems. The effect of this may be to delay revenue recognition. We have experienced and expect to continue to experience delays to our business operations resulting from lack of materials availability, delays in securing key components such as video cameras requiring certain computer chips, and other material and personnel shortages that may impact our ability to implement our products and services in a timely manner or meet required milestones or customer commitments.  In addition, higher costs for travel may adversely impact our business, financial condition, operating results and cash flows. This has made it necessary for the Company to order certain components prior to receiving a contract to ensure we have key components available when necessary to satisfy future contract obligations.

Our products and services may fail to keep pace with rapidly changing technology and evolving industry standards.

The market in which we operate is characterized by rapid, and sometimes disruptive, technological developments, evolving industry standards, frequent new product introductions and enhancements and changes in customer requirements. In addition, both traditional and new competitors are investing heavily in our market areas and competing for customers. As next-generation video analytics technology continues to evolve, we must keep pace in order to maintain or expand our market position. We continue to introduce new product offerings focused on automating mechanical and security inspections in the rail, logistics, intermodal and government sectors as potential revenue drivers. If we are not able to successfully add staff resources with sufficient technical skills to develop and bring these new products to market in a timely manner, achieve market acceptance of our products and services or identify new market opportunities for our products and services, our business and results of operations may be materially and adversely affected.

The market opportunity for our products and services may not develop in the ways that we anticipate.

The demand for our products and services could change quickly and in ways that we may not anticipate. Our operating results may be adversely affected if the market opportunity for our products and services does not develop in the ways that we anticipate or if other technologies become more accepted or standard in our industry or disrupt our technology platforms.

Our revenues are dependent on general economic conditions and the willingness of enterprises to invest in technology.

We believe that operators in the business sectors we are focused on continue to be cautious about sustained economic growth and seek to maintain or improve profitability through cost control and constrained spending. While our core technologies are designed to address cost reduction, other factors may cause companies to delay or cancel capital projects, including the implementation of our products and services. In addition, the business sectors in which we are focused are under financial pressure to reduce capital investment which may make it more difficult for us to close large contracts in the immediate future. We believe there is a growing market trend toward more customers exploring operating expense models as opposed to capital expense models for procuring technology. We believe the market trend toward operating expense models will continue as customers seek ways of reducing their overhead and other costs. All of the foregoing may result in continued pressure on our ability to increase our revenue and may potentially create competitive pricing pressures and price erosion. If these or other conditions limit our ability to grow revenue or cause our revenue to decline our operating results may be materially and adversely affected.

Our working capital profile may shift over time to require additional investment.

Historically, the Company has leveraged significant milestone payments at a contract onset to fund the purchase of required materials. Expansion into a subscription format would allow the Company to potentially transact faster and more routinely with a larger customer base than it has previously had. In certain instances where the Company would build, own and operate its own assets, it may require a different working capital and capitalization strategy whereby the Company will be required to make upfront investments without significant customer milestone payments to offset the investment. The Company believes that this presents a short-term capital risk but will, long-term, improve the overall performance of the business.

Some of our competitors are larger and have greater financial and other resources than we do.

Some of our product offerings compete and will compete with other similar products from our competitors. These competitive products could be marketed by well-established, successful companies that possess greater financial, marketing, distributional, personnel and other resources than we possess. In certain instances, competitors with greater financial resources also may be able to enter a market in direct competition with us offering attractive marketing tools to encourage the sale of products that compete with our products or present cost features that our target end users may find attractive.

We have a history of losses and our growth plans may lead to additional losses and negative operating cash flows in the future.

Our accumulated deficit was approximately $52$64 million as of December 31, 2022.2023. Our operating losses may continue as we continue to expend resources to further develop and enhance our technology offering, to complete prototyping for proof-of-concept, obtain regulatory clearances or approvals as required, expand our business development activities and finance capabilities and conduct further research and development. We also expect to experience negative cash flow in the short-term until our revenues and margins increase at a rate greater than our expenses, which may not occur.

We may be unable to protect our intellectual property, which could impair our competitive advantage, reduce our revenue, and increase our costs.

Our success and ability to compete depend in part on our ability to maintain the proprietary aspects of our technologies and products. We rely on a combination of trade secrets, patents, copyrights, trademarks, confidentiality agreements, and other contractual provisions to protect our intellectual property, but these measures may provide only limited protection. We customarily enter into written confidentiality and non-disclosure agreements with our employees, consultants, customers, manufacturers, and other recipients of information about our technologies and products and assignment of invention agreements with our employees and consultants. We may not always be able to enforce these agreements and may fail to enter into any such agreement in every instance when appropriate. We license from third-parties certain technology used in and for our products. These third-party licenses are granted with restrictions; therefore, such third-party technology may not remain available to us on terms beneficial to us. Our failure to enforce and protect our intellectual property rights or obtain from third parties the right to use necessary technology could have a material adverse effect on our business, operating results, and financial condition. In addition, the laws of some foreign countries do not protect proprietary rights as fully as do the laws of the United States.

Patents may not be issued from the patent applications that we have filed or may file in the future. Our issued patents may be challenged, invalidated, or circumvented, and claims of our patents may not be of sufficient scope or strength, or issued in the proper geographic regions, to provide meaningful protection or any commercial advantage. We have registered certain of our trademarks in the United States and other countries. We cannot assure you that we will obtain registrations of principal or other trademarks in key markets in the future. Failure to obtain registrations could compromise our ability to protect fully our trademarks and brands and could increase the risk of challenge from third parties to our use of our trademarks and brands.

We may be required to incur substantial expenses and divert management attention and resources in defending intellectual property litigation against us.

We cannot be certain that our technologies and products do not and will not infringe on issued patents or other proprietary rights of others. While we are not currently subject to any infringement claim, any future claim, with or without merit, could result in significant litigation costs and diversion of resources, including the attention of management, and could require us to enter into royalty and licensing agreements, any of which could have a material adverse effect on our business. We may not be able to obtain such licenses on commercially reasonable terms, if at all, or the terms of any offered licenses may be unacceptable to us. If forced to cease using such technology, we may be unable to develop or obtain alternate technology. Accordingly, an adverse determination in a judicial or administrative proceeding, or failure to obtain necessary licenses, could prevent us from manufacturing, using, or selling certain of our products, which could have a material adverse effect on our business, operating results, and financial condition.

Furthermore, parties making such claims could secure a judgment awarding substantial damages, as well as injunctive or other equitable relief, which could effectively block our ability to make, use, or sell our products in the United States or abroad. Such a judgment could have a material adverse effect on our business, operating results, and financial condition. In addition, we are obligated under certain agreements to indemnify the other party in connection with infringement by us of the proprietary rights of third parties. In the event that we are required to indemnify parties under these agreements, it could have a material adverse effect on our business, financial condition, and results of operations.

We may incur substantial expenses and divert management resources in prosecuting others for their unauthorized use of our intellectual property rights.

Other companies, including our competitors, may develop technologies that are similar or superior to our technologies, duplicate our technologies, or design around our patents, and may have or obtain patents or other proprietary rights that would prevent, limit, or interfere with our ability to make, use, or sell our products. Although we do not have operations outside North America at this time, we may compete for contracts in other countries in the future. Effective intellectual property protection may be unavailable, or limited, in some foreign countries in which we may do business, such as China. Unauthorized parties may attempt to copy or otherwise use aspects of our technologies and products that we regard as proprietary. Our means of protecting our proprietary rights in the United States or abroad may not be adequate or competitors may independently develop similar technologies. If our intellectual property protection is insufficient to protect our intellectual property rights, we could face increased competition in the market for our technologies and products.

Should any of our competitors file patent applications or obtain patents that claim inventions also claimed by us, we may choose to participate in an interference proceeding to determine the right to a patent for these inventions, because our business would be harmed if we fail to enforce and protect our intellectual property rights. Even if the outcome is favorable, this proceeding could result in substantial cost to us and disrupt our business.

In the future, we also may need to file lawsuits to enforce our intellectual property rights, to protect our trade secrets, or to determine the validity and scope of the proprietary rights of others. This litigation, whether successful or unsuccessful, could result in substantial costs and diversion of resources, which could have a material adverse effect on our business, financial condition, and results of operations.

If we are unable to apply technology effectively in driving value for our clients through technology-based solutions or gain internal efficiencies and effective internal controls through the application of technology and related tools, our operating results, client relationships, growth and compliance programs could be adversely affected.

Our future success depends, in part, on our ability to anticipate and respond effectively to the threat and opportunity presented by new technology disruption and developments. These may include new software applications or related services based on artificial intelligence, machine learning, or robotics. We may be exposed to competitive risks related to the adoption and application of new technologies by established market participants or new entrants, start-up companies and others. These new entrants are focused on using technology and innovation, including artificial intelligence, to simplify and improve the client experience, increase efficiencies, alter business models and effect other potentially disruptive changes in the industries in which we operate. We must also develop and implement technology solutions and technical expertise among our employees that anticipate and keep pace with rapid and continuing changes in technology, industry standards, client preferences and internal control standards. We may not be successful in anticipating or responding to these developments on a timely and cost-effective basis and our ideas may not be accepted in the marketplace. Additionally, the effort to gain technological expertise and develop new technologies in our business requires us to incur significant expenses. If we cannot offer new technologies as quickly as our competitors, or if our competitors develop more cost-effective technologies or product offerings, we could experience a material adverse effect on our operating results, client relationships, growth and compliance programs.

We are dependent on information technology networks and systems to securely process, transmit and store electronic information and to communicate among our locations around North America and with our people, clients, partners and vendors. As the breadth and complexity of this infrastructure continues to grow, including as a result of the use of mobile technologies, social media and cloud-based services, the risk of security breaches and cyberattacks increases. Such breaches could lead to shutdowns or disruptions of or damage to our systems and those of our clients, alliance partners and vendors, and unauthorized disclosure of sensitive or confidential information, including personal data. In the past, we have experienced data security breaches resulting from unauthorized access to our and our service providers’ systems, which to date have not had a material impact on our operations, however, there is no assurance that such impacts will not be material in the future.

In providing services and solutions to clients, we may be required to manage, utilize and store sensitive or confidential client data, possibly including personal data, and we anticipate these activities to increase, including through the use of artificial intelligence, the internet of things and analytics. Unauthorized disclosure of sensitive or confidential client data, whether through systems failure, employee negligence, fraud, misappropriation, or other intentional or unintentional acts, could damage our reputation, could cause us to lose clients and could result in significant financial exposure. Similarly, unauthorized access to our or through our or our service providers’ information systems or those we develop for our clients, whether by our employees or third parties, including a cyberattack by computer programmers, hackers, members of organized crime and/or state-sponsored organizations, who continuously develop and deploy viruses, ransomware or other malicious software programs or social engineering attacks, could result in negative publicity, significant remediation costs, legal liability, damage to our reputation and government sanctions and could have a material adverse effect on our results of operations. Cybersecurity threats are constantly expanding and evolving, thereby increasing the difficulty of detecting and defending against them and maintaining effective security measures and protocols.

We depend on key personnel who would be difficult to replace, and our business plan will likely be harmed if we lose their services or cannot hire additional qualified personnel.

Our success depends substantially on the efforts and abilities of our senior management and certain key personnel. The competition for qualified management and key personnel, especially engineers, is intense. Although we maintain non-competition and non-disclosure covenants with all our key personnel, we do not have employment agreements with most of them. The loss of services of key employees, or the inability to hire, train, and retain key personnel, especially engineers and technical support personnel, could delay the development and sale of our products, disrupt our business, and interfere with our ability to execute our business plan.

Due to our dependence on a limited number of customers, we are subject to a concentration of credit risk.

For the year ended December 31, 2023, three customers accounted for 48%, 30%, and 11% of revenues. For the year ended December 31, 2022, four customers accounted for 42%, 18%, 14% and 14% of revenues. For the year ended December 31, 2021, one customer accounted for 83% of revenues. In all cases, there are no minimum contract values stated. Each contract covers an agreement to deliver a rail inspection portal which, once accepted, must be paid in full, with 30% or more being due and payable prior to delivery. The balances of the contracts are for service and maintenance which is paid annually in advance with revenues recorded ratably over the contract period. Each of the customers referenced has the following termination provisions:

As of December 31, 2022, four2023, two customers accounted for 34%83%, 31%, 19% and 10%11% of our accounts receivable. In the case of insolvency by one of our significant customers, accounts receivable with respect to that customer might not be collectible, might not be fully collectible, or might be collectible over longer than normal terms, each of which could adversely affect our financial position. Additionally, our largest customer accounted for approximately 42%48% of our total revenues for the year ended December 31, 2022.2023. This concentration of credit risk makes us more vulnerable economically. The loss of any of these customers could materially reduce our revenues and net income, which could have a material adverse effect on our business.

Risks Related to Our Common Stock

There is currently not an active liquid trading market for the Company’s common stock.

Our common stock is quoted on the Nasdaq Capital Market tier under the symbol “DUOT”. However, there is currently limited active trading in our common stock. Although there are periodic volume spikes from time to time, we cannot give an assurance that a consistent, active trading market will develop. If an active market for our common stock develops, there is a significant risk that our stock price may fluctuate in the future in response to any of the following factors, some of which are beyond our control:

You may experience dilution of your ownership interest due to future issuanceissuances of our securities.

We are in a capital-intensive business, and we may not have sufficient funds to finance the growth of our business or to support our projected capital expenditures. As a result, we may require additional funds from future equity or debt financings, including potential sales of preferred shares or convertible debt, to complete the development of new projects and pay the general and administrative costs of our business. We may in the future issue our previously authorized and unissued securities, resulting in the dilution of the ownership interests of holders of our common stock. We are currently authorized to issue 500,000,000 shares of common stock and 10,000,000 shares of preferred stock. We may also issue additional shares of common stock or other securities that are convertible into or exercisable for common stock in future public offerings or private placements for capital raising purposes or for other business purposes. The future issuance of a substantial number of shares of common stock into the public market, or the perception that such issuance could occur, could adversely affect the prevailing market price of our common shares. A decline in the price of our common stock could make it more difficult to raise funds through future offerings of our common stock or securities convertible into common stock.

Our Board of Directors may issue and fix the terms of shares of our Preferred Stock without stockholder approval, which could adversely affect the voting power of holders of our Common Stock or any change in control of our Company.

Our Articles of Incorporation authorize the issuance of up to 10,000,000 shares of "blank check" preferred stock, with such designations rights and preferences as may be determined from time to time by the Board of Directors. Our Board of Directors is empowered, without shareholder approval, to issue shares of preferred stock with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of the holders of our common stock. In the event of such issuances, the preferred stock could be used, under certain circumstances, as a method of discouraging, delaying, or preventing a change in control of our Company. 

We do not expect to pay dividends and investors should not buy our common stock expecting to receive dividends.

We do not anticipate that we will declare or pay any dividends in the foreseeable future. Consequently, you will only realize an economic gain on your investment in our common stock if the price appreciates. You should not purchase our common stock expecting to receive cash dividends. Accordingly, our stockholders will not realize a return on their investment unless the trading price of our common stock appreciates, which is uncertain and unpredictable. In addition, because we do not pay dividends, our common stock may be less attractive, which may cause us to have trouble raising additional funds which could affect our ability to expand our business operations.

Our operating results are likely to fluctuate from period to period.

We anticipate that there may be significant fluctuations in our future operating results. Potential causes of future fluctuations in our operating results may include:

We are subject to the Florida anti-takeover provisions, which may prevent you from exercising a vote on business combinations, mergers or otherwise.

As a Florida corporation, we are subject to certain anti-takeover provisions that apply to public corporations under Florida law. Pursuant to Section 607.0901 of the Florida Business Corporation Act, or the Florida Act, a publicly held Florida corporation, under certain circumstances, may not engage in a broad range of business combinations or other extraordinary corporate transactions with an interested shareholder without the approval of the holders of two-thirds of the voting shares of the corporation (excluding shares held by the interested shareholder).

An interested shareholder is defined as a person who together with affiliates and associates beneficially owns more than 15% of a corporation’s outstanding voting shares. We have not made an election in our amended Articles of Incorporation to opt out of Section 607.0901.

In addition, we are subject to Section 607.0902 of the Florida Act which prohibits the voting of shares in a publicly held Florida corporation that are acquired in a control-share acquisition unless (i) our board of directors approved such acquisition prior to its consummation or (ii) after such acquisition, in lieu of prior approval by our board of directors, the holders of a majority of the corporation’s voting shares, exclusive of shares owned by officers of the corporation, employee directors or the acquiring party, approve the granting of voting rights as to the shares acquired in the control-share acquisition. A control-share acquisition is defined as an acquisition that immediately thereafter entitles the acquiring party to 20% or more of the total voting power in an election of directors.

The Company, however, shall not effect any conversion of the Series F Preferred Stock, and the holder shall not have the right to convert any portion of the Series F Preferred Stock, to the extent that after giving effect to the conversion sought by the holder such holder (together with such holder’s Attribution Parties (as defined in the Certificate of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%) of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon such conversion. The purchasers of the Series F Preferred Stock elected that their ownership limitation would be 19.99%.

The holders of the Series F Preferred Stock, the holders of the common stock and the holders of any other class or series of shares entitled to vote with the common stock shall vote together as one class on all matters submitted to a vote of shareholders of the Company. Each share of Series F Preferred Stock has 161 votes (subject to adjustment); provided that in no event may a holder of Series F Preferred Stock be entitled to vote a number of shares in excess of such holder’s ownership limitation.

The Company also agreed that it would not, with certain exceptions, sell or issue common stock or Common Stock Equivalents (as defined in the Purchase Agreement relating to the Series F Preferred Stock) on or prior to December 31, 2023 that entitled any person to acquire shares of common stock at an effective price per share less than the then conversion price of the Series F Preferred Stock without the consent of the holders. As a result of that agreement, upon the issuance of 2,500 shares of Series E Preferred Stock (which have a conversion price of $3.00 per share) on November 10, 2023, the holders exchanged their 5,000 shares of Series F Preferred Stock for 5,000 shares of Series E Preferred Stock.

All of the shares of Series F Preferred Stock thereupon were cancelled. As of December 31, 2023 and December 31, 2022, respectively, there were 0 and 0 shares of Series F Convertible Preferred Stock issued and outstanding.

Plan of Operation

The Company’s growth strategy includes expansion of its technology base through organic development efforts, strategic partnerships, and strategic acquisitions where appropriate. The Company provides its broad range of technology solutions with an emphasis on the Vision Technology market sector and, more specifically, the Machine Vision subsector. Machine Vision companies provide imaging-based automatic inspection and analysis for process control for industry with potential expansion into other markets. Duos is currently developing industry solutions for its target markets which will address rail, trucking, aviation and other vehicle-based processes. DuosDuos’ initial offering, the Railcar Inspection Portal (RIP), provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated railcar inspections of trains while they are moving at full speed.

Specifically, based upon the current and anticipated business growth, the Company is investing in resources to focus on execution within its target markets. We continue to evaluate key requirements within those markets, our go-to-market strategy and add development resources to allow us to compete for additional projects to drive additional revenue growth.

Prospects and Outlook

The Company made significant changes to its senior management team coming out of the COVID-19 pandemic to improve operational effectiveness. In addition to new “C” level personnel, the Company replaced its software and AI team with stronger talent including promoting one of the senior leaders to the position of Chief Technology Officer. The Company also replaced its Commercial team with seasoned rail industry personnel to improve it’s go-to-market plan with current and prospective customers. The Company’s Board of Directors was strengthened with the addition of experienced leaders. Additionally, the company retained a number of long-term former rail industry executives in advisory roles to help guide the Company’s growth strategy.

The leadership team’s focus is to improve operational and technical execution which, we believe, will in turn enable the commercial side of the business to expand our product setRIP and ALIS delivery into existing customers and to expand and diversify our current customer base. The travel and quarantine restrictions surrounding COVID-19 have largely diminished in 2021 and 2022 and the Company’s primary customers have indicated readiness to order more equipment and services should the Company execute as expected on key deliverables overdeliverables. With the next few months.Company working toward a subscription platform approach and its expansion of its artificial intelligence offering, this will also open up additional commercial avenues to the Company. Historically, the Company has been focused on large, one-time sales with the subscription opportunities representing an expanded addressable market with emphasis on recurring revenues.

Additionally, the new CEO has directed that the Company makeis making engineering and software upgrades to the RIP to meet anticipated Federal Railroad Association (FRA), Transport Canada and Association of American Railroad (AAR) standards. These upgrades will continue to be released throughout 2024 and are expected to drive revenue growth this year and beyond.

The Company is expanding its focus in the rail industry to encompass passenger transportation and is currently in the process of delivering high-speed portals forwas awarded a large, multi-year contract with a national rail carrier. The Company is expected to deliver at least two RIP solutions alonganticipates that it will install a two-RIP solution for the carrier in 2024, with the initiation of a long-term services agreement during 2023.

In addition,commencing upon delivery of the Company is currently investigating other possible market expansion including Aviation, Trucking and Edge Data Centers.system.

Although the Company’s prospects and outlookfor future revenue growth are anticipated to be favorable, for 2023, investing in our securities involves risk and careful consideration should be made before deciding to purchase our securities. There are many risks that affect our business and results of operations, some of which are beyond our control and unexpected macro events can have a severe impact on the business. Please see the risk factors identified in “Item 1A – Risk Factors” elsewhere in this Annual Report.

Results of Operations

The following discussion should be read in conjunction with the consolidated financial statements included in this report.

For the year ended December 31, 20222023 compared to December 31, 20212022

The following table sets forth a summary of our Consolidated Statements of Operations that is used in the following discussions of our results of operations:

Revenues

For the full year 2022,2023, there was an 82%a 50% decrease in overall increase in revenues compared to 2021. The increase2022. This decrease was primarily driven by new revenues being recorded after lengthy delaysthe substantial completion of two freight RIP projects, alongside ongoing procurement and manufacturing for our transit-focused RIPs in receiving “notices to proceed” for anticipated new contracts earlier2022. However, in the year that pushed delivery dates2023, despite progress into the second halfadvanced stages of 2022procurement and manufacturing for the transit-focused RIPs, customer-driven delays beyond the Company’s control arose during the ongoing production of the two high-speed transit-focused RIPs and thus resulted in timing delays of the overall project delivery timeline shifting anticipated revenues into 2023. There2024. For the full year 2023, there was a significantsmall increase in revenue from systems with a slightly lower increase in service revenues of 60% year-over-year. The increase in revenues stems directly from the delivery of two RIP projects across 2022 in addition to the onset of a new high-speed RIP project which the Company will continue to recognize well into 2023. Additionally, the growth in services and consulting stems fromrevenues as there were one-time services performed in 2022, related to major site maintenance and repairs for a single customer which did not occur in 2023. Underlying recurring revenues climbed by approximately 23% on a year-over-year basis. This growth is fueled by the Company’s successexpansion of service contracts following the completion of new portals in deploying artificial intelligence as well as change orders to existingearly 2023, coupled with the deployment of AI services agreements during the year.deployed with several customers. The Company is focusing on increasing its business from services and the increase is the result of new contracts for existing and new systems which the Company anticipates will continue growing throughout 20232024 and beyond. As previously discussed, managementThe Company continues to navigate delays outside of the Company's control related to the ongoing production and installation of our two high-speed transit-focused Railcar Inspection Portals. Management cautions that because of the delays in anticipated start dates, certain installations may produce revenues towards the end of 2023. Additionally, although the industries in which we operate have improved after the Covid-19 pandemic, other macro-economic effects are anticipated to impact us, including inflation and the current supply chain issues which are extending deadlines for shipment of key components used in our technology systems. The effect of this deferred some revenue recognition into 2023 as previously mentioned.2024. These deferrals resulted in a slightly lower revenue growth performance than originally anticipated. However, the bulk of these deferred revenues are expected to be reported in 2023. The effects of inflation are not fully quantifiable at the current time but are beginning to be evident in increased costs for materials and labor and may result in higher costs for project implementation that cannot be wholly or even partially passed on to our customers and thus resulting in delaying our progress towards profitability.2024.

The Company’sWhile customer-driven delays in the installation of our high-speed transit-focused Railcar Inspection Portals have impacted revenue growth timing year-over-year, the Company's capital structure continues to allow us to weather the unexpected delays without significant operational impact and enablesremains resilient, allowing us to pursue large projects where the ability to deploy major resources is required.despite unexpected delays. It should be noted that the Company recently increased its working capital to account for an increase in pre-contract procurement activities to avoid a slowdown in revenues caused by delays in receiving certain components as had been the case in previous years. The Company undertook a major review of operations during 2021 and made significant changes in staffing including additional engineering staff and revamping its software development and Artificial Intelligence staffing. These efforts have begun to yieldyielded benefits throughout 2022, 2023 and beyond.

Overall, in 2022 as reflected in the improved systems revenues. This effort has improved delivery times on major projects and helps to offset some of the continued supply chain lags2023, the Company has faced post-Covid-19. The Company continues to monitorachieved notable success in advancing procurement and manufacturing for its transit-focused RIPs, expanding service contracts, and securing new AI contracts and growing its AI portfolio, including the situation and procures materials aheadannouncement of contract award where feasible.

The Company also expects to continue the growth with newits inaugural subscription customer. Recurring revenue from other existing customers which we expect to be coming on-line in the next several months. In aggregate during 2022, the Company has been successful in the expansion of project and services contracts to account for new work. The services portion of revenues are driven by successful completion on projects and represents services and support for those installations. The recurring revenue portion of our revenue for services and consulting continues to make-up a greater share of our revenuesgrow and this growth is expected to continue going forward. The Company expectscontribute significantly to continue the growthfuture revenue streams, bolstered by new long-term contracts with new, long term recurring revenue from existing customers which will be coming on-lineexpected to commence in the next severalcoming months.

Cost of Revenues

Cost of revenues largely comprises equipment, certain fixed labor and overhead necessary to support the implementation of new systems and support and maintenance of existing systems. Cost of revenues on technology systems increaseddecreased during the period compared to the equivalent period in 2021 by a slightly lower rate than2022 in-line with the increasedecline in project revenues. The primary reason for the increased growthdecline in costs generally follows the same trend as project revenues year-over-year stems from additionalas a result of an overall timing difference of major project work related to the deliverysubstantial completion of two freight Railcar Inspection Portals. Additionally,Portals and subsequent progression of procurement and manufacturing for the transit-focused RIPs compared to the equivalent period in 2023 where the Company made significantcontinued to progress oninto the advanced stages of procurement and manufacturing of a special-purpose, high value Railcar Inspection Portalthe transit-focused RIPs, which it anticipates completing during 2023. The Company’s costs are composed of materials, subcontractor costs and labor consisting of the Company’s engineering, project management and software team’s efforts to deliver on the aforementioned Railcar Inspection Portals. The cost of sales grew at a slower pace than revenues primarily because the Company neared completion of two of its portals and thus recognized additional profits on these projects as it satisfied its project-related obligations. Additionally, the Company saw improved revenue growth related to higher margin services and artificial intelligence during the year which contributed to revenue growth outpacing the change in cost of sales.2024.

These internal costs are being recognized against project and support revenues with a similar reduction in costs previously recognized for research and development, engineering development and internal support. The project costs reflect subsequent allocations of fixed costs related to the staff and departmental costs associated with procurement, manufacturing and installation of RIP installations. As such, in 2023, this fixed component contributed to a negative margin on the Technology systems revenues. In concert with this, there is a continued focus on construction costs and savings through efficiency, but the Company has elected to expandretain its key employees in anticipation of expected sales growth in technology systems and services in 20232024 and beyond.

Cost of revenues increaseddecreased on services and consulting year-over-year albeit at a slower pace than the increase in services and consulting revenues.year-over-year. The increasedecrease in costs was a result of one-timeone-time services completed on existing RIP sites on whichperformed in 2022, related to major site maintenance and repairs for a single customer slightly offset by additional services costs related to the Company incurred some additional material costs as well as project management and engineering team labor to complete the project. The year-over-year revenue from consulting and services increase outpaced the increasecompletion of two new freight portals in costs which is a positive trend.early 2023. The Company continues to put into service additional artificial intelligence algorithms and maintenance and support services which are high margin and represent only marginal increases in the requisite costs to deliver these services.

Gross Margin

Gross margin showed a significant improvementdecrease for the year ended December 31, 20222023 as compared to the same period in 2021.2022. As noted above, the improvementdecline in margin was a direct result of an increased level of business activity the Company recognized in 2022 related to the delivery of two freight portals and the progression of the transit-focused RIPs compared to the activity in 2023 as well as project delays that were experienced in the latter half of 2022.2023. The increased business activity was related toin 2023 consisted primarily of continued progression into the advanced stages of procurement and manufacturing and near completion of installation of two Rail Inspection Portals, a number of one-time service events and significant progress made on a special-purpose, high-value RIP.for the transit-focused RIPs. The Company began to recognize revenue and profit on those activities in accordaccordance with its revenue recognition policy. The recognition of the revenue and subsequent profit from these projects, as well as underlying services and maintenance revenues from existing and recently completed projects, coupled with the previously mentioned fixed departmental costs resulted in a gross margin of approximately 18%. By comparison for the full-year 2022, the Company had increased business activity from a handful of projects primarily related to the substantial completion of two freight RIPs along with significant progress made on the procurement and manufacturing of our two transit-focused RIPs. The recognition of the revenue and subsequent profit from these major projects, as well as underlying services and maintenance revenues from existing projects, resulted in a 32% gross margin. By comparison for the full-year 2021, the Company had limited business activity from a handful of projects primarily related to customer site upgrades as well as lower underlying service revenues. This was as a result of project timing and delayed A.I. related services, which yielded a 25% gross margin. While the margins are not significantly different year-over-year, the Company’s 82% increasemargin in revenue from additional projects and services drove an overall higher gross margin-dollar amount.2022.

Operating Expenses

Overall operating expenses were higher by 22%10% in 20222023 as compared to the full-year 2021.2022. There was a marginal 8%12% increase in sales and marketing related to increased investment into the overall capability of the commercial team. Specifically, 2022 sawteam, including the Company bringaddition of professionals with extensive experience and leadership in additional talent with direct experience from the technology and rail spaces.industry. Research and development costs declined 34%saw a 10% uptick during the year. This wasyear, driven by the result of some of the technical resources from the IT and Engineering teams being consumed as part of the significant increase in project and service revenues and ledincreased personnel costs related to the Company performing additional project and one-time services work year-over-year. The offset of these charges residedepartments allocated to R&D. Additionally, a 10% increase in the cost of sales services and consulting. Additionally, general and administration costs increased approximately 50% because ofwas influenced by several factors, including non-cash amortization charges associated with roughly 400,000 share options that were issued during 2023 as well as an increase in incentive programs tied to certain 2022 performance targets. These efforts reflect a focus on employee retention and increased headcount to support the growth in its operating plan. Specifically, in 2022 the Company had charges related to staff retention via a discretionary performance program; this was a new initiative for the entire organization to drive higher performance and attract and retain better quality resources in a tight labor market as well as the related implementation and increased subsequent non-cash charges of an employee stock option plan.market. The Company still faces some pressure on existing staff compensation as a result of inflation during 2022in prior years but remains focused to manage and stabilize administrative costs without interruption to customer service. Other factors driving the increase in general and administration costs include an increase in depreciation charges linked to capitalized AI development cost for third party support to expand Duos’ AI catalog to over 40 algorithms by the end of 2023. Lastly the Company saw increased general and administration costs related to a financing deal which was ultimately not consummated with a bank as well as additional legal and consulting fees related to intellectual property and patents documentation and support. These changes in expenses reflect the Company's ongoing efforts to invest in talent, expand capabilities, and drive growth in line with its operating plan.

Loss From Operations

The losses from operations for the years ended December 31, 2023 and 2022 were $11,446,566 and 2021 were $6,865,149, and $7,456,951, respectively. The decreaseincrease in losses from operations during the year was the result of mostly improveddeclining system revenues stemming from the deployment of new portals and receipt of materials and manufacturing related to a high value set of portals to be completed during 2023. These additional projectsdecrease in business activity as well as an increaseproject delays experienced in services and consulting revenue increases and related margins outpacedthe latter half of 2023 that were beyond the Company’s increased general and administrative costs throughout 2022. As a result, the Company achieved near breakeven in the fourth quarter of 2022.control. The Company has continued to face inflation and supply chain pressures during 20222023 and, as normal course of business, has worked to balance these impacts through management of customer contracts and cost control efforts.

Interest Expense

Interest expense for the years ended December 31, 2023 and 2022 was $7,159 and 2021 was $9,191, and $20,268, respectively. The reduction in interest expense was primarily dueattributed to the extinguishment of equipment financing charges related to insurance policiespayables in 2021.2023 that were present during 2022.

Other Income

Other income for the years ended December 31, 2023 and 2022 was $212,007 and 2021 was $9,557, and $1,468,318, respectively. The decreaseincrease is mainly dueattributable to the PPP loan forgiveness recordedCompany's sale of its iCAS assets to a purchaser in the firstsecond quarter of 2021.2023 for $165,000 through a convertible note.

Net Loss

The net loss for the years ended December 31, 2023 and 2022 was $11,241,718 and 2021 was $6,864,783, and $6,008,901, respectively. The increase in net loss is primarily attributable to the one-time effect of the PPP loan forgiveness gaindecrease in project activity in 2023 compared to 2022, offset slightly with an increase in the first half of 2021. Despite the increased net loss year-over-year, the Company showed an improvement at the operating loss level.Company’s recurring services and consulting. Net loss per common share was $1.11$1.56 and $1.63$1.11 for the years ended December 31, 20222023 and 2021,2022, respectively.

Liquidity and Capital Resources

As of December 31, 2022,2023, the Company has a cash balance of $1,121,092.$2,441,842 and an Accounts Receivable balance of $1,462,463.

Cash Flows

The following table sets forth the major components of our statements of cash flows data for the periods presented:

Net cash used in operating activities for the years ended December 31, 2023 and 2022 was $8,746,564 and 2021 was $7,873,307, and $6,579,378, respectively. The increase in net cash used in operations for the year ended December 31, 20222023 was the result of higher expenditures related to current projects as previously discussed as well as expenditures related to projects which the Company anticipates will be completed in 2023.2024. In addition, there are several changes in assets and liabilities that increased the use of cash in operations including increasesdecreases in inventory for some long-lead componentsaccounts payable, accrued expenses and accounts receivable. Additionally, $1,410,270 in funding from the CARES Act PPP loan program received in 2021 plus deferred interest was forgiven during the first quarter of 2021.operating lease obligation.

Net cash used in investing activities for the years ended December 31, 2023 and 2022 was $1,093,909 and 2021 was $644,888, and $552,940, respectively. The Company continuescontinued to invest in computing, lab equipment, andinternal use software and artificial intelligence detections development as reflected in the year-over-year increase in 2022.2023.

Net cash provided in financing activities for the years ended December 31, 2023 and 2022 was $11,161,223 and 2021 was $8,745,567, and $4,056,938, respectively. Cash flows provided by financing activities during 20222023 were primarily attributable to gross proceeds from the issuance of common and preferred stock to shareholders in the amount of $10,100,004,$11,500,000, offset by $942,946$25,797 in issuance costs. 20222023 marked an increase from 20212022 financing activities $4,056,938 which was primarily underpinned from the gross proceeds of a private placement of $4,500,000.$8,745,567.

During 2022,2023, we funded our operations through the sale of our equity (or equity linked) securities, and through revenues generated and cash received from ongoing project execution, services and associated maintenance revenues. As of March 28, 2023,27, 2024, we have cash on hand of approximately $4,500,000.$3,329,753 after an equity capital raise in March 2024 which provided net proceeds of $2,745,000. We have approximately $165,500 in monthly lease and other mandatory payments, not including payroll and ordinary expenses which are due monthly.

On a long-term basis, our liquidity is dependent on the continuation and expansion of operations and receipt of revenues. Our current capital and access to further capital and revenues are sufficient to fund such expansion we are now less dependent on timely payments by our customers for projects and work in process, however we expect such timely payments to continue. Material cash requirements will be satisfied within the normal course of business including substantial upfront payments from our customers prior to starting projects. In some cases, the Company may elect to purchase materials and supplies in advance of contract award but where there is a high probability of that award. Most, if not all, high value items that are pre-purchased, can be re-purposed if necessary. The maximum amount of material cash requirements not currently supported by up-front customer deposits is expected to be less than $1 million.

Demand for the products and services will be dependent on, among other things, market acceptance of our products and services, the technology market in general, and general economic conditions, which are cyclical in nature. In as much as a major portion of our activities is the receipt of revenues from the sales of our products and services, our business operations may be adversely affected by our competitors and prolonged recession periods although these are not considered to be a factor at present.

In the event of expansion into owning and operating its own Railcar Inspection Portals, the Company’s cash requirements and timing may shift. Specifically, the Company would endeavor to buy all materials ahead of time and invest in the RIP with follow-on contracts for long-term services and licensing. While this would shift the Company’s cash requirements, it anticipates a 12 – 18 month18-month cash break-even point for each site and an opportunity for improved cash flows over time with high-margin agreements with the investment bolstered by access to further funding via common stock and private placement offerings.

Liquidity

Under Accounting Codification ASC 205, Presentation of Financial Statements—Going Concern (Subtopic 205-40) (“ASC 205-40”), the Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date that the financial statements are issued. As required by ASC 205-40, this evaluation shall initially not take into consideration the potential mitigating effects of plans that have not been fully implemented as of the date the financial statements are issued. Management has assessed the Company’s ability to continue as a going concern in accordance with the requirement of ASC 205-40.

As reflected in the accompanying consolidated financial statements, the Company had a net loss of $6,864,783$11,241,718 for the year ended December 31, 2022.2023. During the same period, cash used in operating activities was $7,873,307.$8,746,564. The working capital surplus and accumulated deficit as of December 31, 2022,2023, were $2,339,052$3,009,842 and $52,361,834,$63,603,552, respectively. In previous financial reports, the Company had raised substantial doubt about continuing as a going concern. This was principally due to a lack of working capital prior to an underwritten offerings and a private placementplacements which were completed during the first, quarter of 2022 and during third and fourth quarters of 2022, the first, third and fourth quarters of 2023, as well as the first quarter of 2023. 2024.

As previously noted, the Company raised $4,500,000 from existing shareholders through the issuance of Series C Convertible Preferred Stock during 2021. Additionally, the Company was successful during 20222023 in raising gross proceeds of over $10,100,000$11,500,000 from the sale of both common sharesSeries E and Series DF Preferred Stock. Additionally, late in the first quarter of 2023,2024, the Company raised gross proceeds of $4,000,000$2,745,000 from the issuance of a combination of Series D and E Preferred Stock (See Note 16)17). As part of its strategy, the Company will endeavor to utilize the Preferred Series E and the remainder of the Series D as additional funding mechanisms. Additionally, during the second quarter of 2023,2024, the Company will again have access to its S-3 “shelf registration” statement allowing the Company to sell additional common shares. At the time of this document, the Company estimates that it has available capacity on its shelf registration which it can utilize to bolster working capital and growth of the business in the event it did not have an uptake in the preferred classes of shares previously noted. Although additional investment is not assured, the Company is comfortable that it would be able to raise sufficient capital to support expanded operations based on an anticipated increase in business activity. In the long run, the continuation of the Company as a going concern is dependent upon the ability of the Company to continue executing its business plan, generate enough revenue, and attain consistently profitable operations. Although the lingering effects of the global pandemic related to the coronavirus (Covid-19) continue to affectpreviously affected our operations, particularly in our supply chain, we now believe that this is expected to be an ongoing issue and our working capital assumptions reflect this new reality. The Company cannot currently quantify the uncertainty related to the ongoing supply chain issues and its effects on our customers in the coming quarters.lags have largely been abated. We have analyzed our cash flow under “stress test” conditions and have determined that we have sufficient liquid assets on hand or available via the capital markets to maintain operations for at least twelve months from the issuance date of this report.

In addition, management has been takingtaken and continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue, and re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and profitability and focusing product strategy on opportunities that are likely to bear results in the relatively short term. The Company believes that, with the combination of commercial sales success, Series E Preferred Stock offering coupled with an S-3 shelf registration availability starting in the second quarter of 2023,2024, it will have sufficient working capital to meet its obligations over the following twelve months. In the last twelve months the Company has seen significant growth in its contracted backlog as well as significant, positive signs from new commercial engagementsprojects that indicate improvements in future commercial opportunities.revenues.

Management believes that, at this time, the conditions in our market space with ongoing contract delays the consequent need to procure certain materials in advance of a binding contract and the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent common stock offerings and private placements as well as the availability to raise capital via its shelf registration indicate there is no substantial doubt for the Company to continue as a going concern for a period of twelve months. We continue executing the plan to grow our business and achieve profitability. The Company may selectively look at opportunities for fund raising in the future. Management has extensively evaluated our requirements for the next 12 months and has determined that the Company currently has sufficient cash and access to capital to operate for at least that period.

While no assurance can be provided, management believes that these actions provide the opportunity for the Company to continue as a going concern and to grow its business and achieve profitability with access to additional capital funding. Ultimately the continuation of the Company as a going concern is dependent upon the ability of the Company to continue executing the plan described above which was put in place in late 2022 and will continue in 20232024 and beyond. As a result, we expect to generate sufficient revenue and to attain profitable operations with minimal cash use in the next 1212-18 months. These consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Critical Accounting Estimates

Revenue Recognition

The Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue to recognize. The Company follows Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), that affects the timing of when certain types of revenues will be recognized. The basic principles in ASC 606 which include the following: a contract with a customer creates distinct contract assets and performance obligations, satisfaction of a performance obligation creates revenue, and a performance obligation is satisfied upon transfer of control to a good or service to a customer.

Revenue is recognized by evaluating ourthe Company revenue contracts with customers based on the five-step model under ASC 606:

1. Identify the contract with the customer;

2. Identify the performance obligations in the contract;

3. Determine the transaction price;

4. Allocate the transaction price to separate performance obligations; and

5. Recognize revenue when (or as) each performance obligation is satisfied.

The Company generates revenuesrevenue from four sources:

1. Technology Systems;

2. AI Technology;

3. Technical Support; and

4. Consulting Services.

Technology Systems

For revenues related to technology systems, the Company recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue to recognize.

Accordingly, the Company bases its technology systems revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods are manufactured and revenue is recognized accordingly.

In addition, the Company has adopted ASC 606-10-55-21 such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192.

Under this method, contract revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in “contract assets”. Any billings of customers more than recognized revenues are recorded as a liability in “contract liabilities”. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.

AI TechnologiesStock Based Compensation

The Company has revenue from applications that incorporate artificial intelligence (AI)accounts for employee and non-employee stock-based compensation in accordance with ASC 718-10, “Share-Based Payment,” which requires the formmeasurement and recognition of predetermined algorithms which provide important operating informationcompensation expense for all share-based payment awards made to employees and directors including stock options, restricted stock units, and employee stock purchases based on estimated fair values. The stock-based compensation carries a graded vesting feature subject to the userscondition of our systems. The revenue generated from these applicationstime of AI consists of a fixed fee related toemployment service with awarded stock-based compensation tranches vesting evenly upon the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue at a point in time upon customer acceptance, as well as an annual application maintenance fee, which is recognized as revenue ratably over the contracted maintenance term.

Technical Support

Technical support services are provided on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided outside of a maintenance contract are on an “as-requested” basis, and revenue is recognized over time as the services are provided. Revenue for maintenance and technical support provided on an extended-term basis is recognized over time ratably over the termanniversary date of the contract.

Consulting Services

The Company’s consulting services business generates revenues under contracts with customers from four sources: (1) Professional Services (consulting and auditing); (2) Software licensing with optional hardware sales; (3) Customer service training and (4) Maintenance support.

(1) Revenues for professional services, which are of short-term duration, are recognized when services are completed;

(2) For all periods reflected in this report, software license sales have been one-time sales of a perpetual license to use our software product and the customer also has the option to purchase third-party manufactured handheld devices from us if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware, as applicable, to the customer;

(3) Training sales are one-time upfront short-term training sessions and are recognized after the service has been performed; and

(4) Maintenance/support is an optional product sold to our software license customers under one-year contracts. Accordingly, maintenance payments received upfront are deferred and recognized over the contract term.

Multiple Performance Obligations and Allocation of Transaction Price

Arrangements with customers may involve multiple performance obligations including project revenue and maintenance services in our Technology Systems business. Maintenance will occur after the project is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business, multiple performance obligations may include any of the above four sources. Training and maintenance on software products may occur after the software product sale while other services may occur before or after the software product sale and may not relate to the software product. Revenue recognition for a multiple performance obligations arrangement is as follows:

Each performance obligation is accounted for separately when each has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable. For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated, the revenue for each performance obligation is recognized using the applicable criteria under GAAP as discussed above for performance obligations sold in single performance obligation arrangements. A delivered item or items that do not qualify as a separate unit of accounting within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific objective evidence of selling price for purposes of performance obligations relative selling price allocation. The Company only sells maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer. The customer is not required to purchase maintenance services. All elements in multiple performance obligations arrangements with Company customers qualify as separate units of account for revenue recognition purposes.

Accounts Receivable

Accounts receivable are stated at estimated net realizable value. Accounts receivable are comprised of balances due from customers net of estimated allowances for uncollectible accounts. In determining the collections on the account, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances. The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based on how recently payments have been received from customers.

Long-Lived Assetsaward.

The Company evaluatesestimates the recoverabilityfair value of its property, equipment, and other long-lived assets instock options granted using the Black-Scholes option-pricing formula. In accordance with FASB ASC 360-10-35-15 “Impairment or Disposal of Long-Lived Assets”, which requires recognition of impairment of long-lived assets in718-10-35-8, the event the net book values of such assets exceed the estimated future undiscounted cash flows attributableCompany elected to such assets or the business to which such intangible assets relate. This guidance requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceedsrecognize the fair value of the assets. Assets to be disposedstock award using the graded vesting method as time of are reported atemployment service is the lowercriteria for vesting. The Company amortizes the fair value of the carrying amount orstock award over the requisite service periods of the awards, which is generally the vesting period. The Company’s determination of fair value less costs to sell.using an option-pricing model is affected by the stock price as well as assumptions regarding a number of highly subjective variables.

The Company estimates volatility based upon the historical stock price of the Company and estimates the expected term for stock options using the simplified method for employees and directors and the contractual term for non-employees. The risk-free rate is determined based upon the prevailing rate of United States Treasury securities with similar maturities.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

With the participation of our Chief Executive Officer, Chief Financial Officer and Controller, we have evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by this Report. Based upon such evaluation, our Chief Executive Officer, Chief Financial Officer and Controller have concluded that, as of the end of such period, our disclosure controls and procedures were not effective due to material weaknesses in internal controls over financial reporting discussed below to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer, Chief Financial Officer and Controller, as appropriate to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Our management, under the supervision and with the participation of our Chief Executive Officer, Chief Financial Officer and Controller, evaluated the effectiveness of our internal control over financial reporting as of the end of the period covered by this report. In making this assessment, our management used the criteria set forth in the framework contained in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, our management concluded that our internal control over financial reporting was not effective as of the end of the period covered by this report based on those criteria.

Our internal control over financial reporting is a process designed under the supervision of our Chief Executive Officer, Chief Financial Officer and Controller to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles, or GAAP. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

With the participation of our Chief Executive Officer, Chief Financial Officer and Controller, we have evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by this Report. Based upon such evaluation, our Chief Executive Officer, Chief Financial Officer and Controller have concluded that, as of the end of such period, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer, Chief Financial Officer and Controller, as appropriate to allow timely decisions regarding required disclosure.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Changes in Internal Control over Financial Reporting

In connection with the audit of our consolidated financial statements for the year ended December 31, 2022, management identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

As of December 31, 2022, the material weaknesses in our internal control over financial reporting related to the ineffective review of revenue recognition policy and application of policy related to services and project scopes of work. Business financial review controls proved ineffective as a result of reliance upon ineffective reporting software, or that rely on data produced from numerous sources such as customer supply agreements..

Notwithstanding our material weakness, we have concluded that the financial statements and other financial information included in this Annual Report fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States.

Planned Remediation Activities

Our planned remediation efforts related to the above identified material weakness include:

There were no further changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the year ended December 31, 20222023, that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) for the quarter ended December 31, 2023, that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Equity Compensation Plan Information

2021 Equity Plan

On May 12, 2021, the Board adopted, with shareholder approval, the 2021 Equity Incentive Plan (the “2021 Plan”) providing for the issuance of up to 1,000,000 shares of our Common Stock. The purpose of the 2021 Plan is to assist the Company in attracting and retaining key employees, directors and consultants and to provide incentives to such individuals to align their interests with those of our shareholders.

General Description of the 2021 Plan

The following is a summary of the material provisions of the 2021 Plan and is qualified in its entirety by reference to the complete text of the 2021 Plan, which you are encouraged to read in full.

Administration

The 2021 Plan is administered by the Compensation Committee of the Board, which consists of three members of the Board, each of whom is a “non-employee director” within the meaning of Rule 16b-3 promulgated under the Exchange Act and an “outside director” within the meaning of Code Section 162(m). Among other things, the Compensation Committee has complete discretion, subject to the express limits of the 2021 Plan, to determine the directors, employees and nonemployee consultants to be granted an award, the type of award to be granted, the terms and conditions of the award, the form of payment to be made and/or the number of shares of Common Stock subject to each award, the exercise price of each option and base price of each stock appreciation right (“SAR”), the term of each award, the vesting schedule for an award, whether to accelerate vesting, the value of the Common Stock underlying the award, and the required withholding, if any. The Compensation Committee may amend, modify or terminate any outstanding award, provided that the participant’s consent to such action is required if the action would impair the participant’s rights or entitlements with respect to that award. The Compensation Committee is also authorized to construe the award agreements and may prescribe rules relating to the 2021 Plan. Notwithstanding the foregoing, the Compensation Committee does not have any authority to grant or modify an award under the 2021 Plan with terms or conditions that would cause the grant, vesting or exercise thereof to be considered nonqualified “deferred compensation” subject to Code Section 409A.

Grant of Awards; Shares Available for Awards

The 2021 Plan provides for the grant of stock options, SARs, performance share awards, performance unit awards, distribution equivalent right awards, restricted stock awards, restricted stock unit awards and unrestricted stock awards to non-employee directors, officers, employees and nonemployee consultants of the Company or its affiliates. We have reserved a total of 1,000,000 shares of Common Stock for issuance as or under awards to be made under the 2021 Plan. If any award expires, is cancelled, or terminates unexercised or is forfeited, the number of shares subject thereto is again available for grant under the 2021 Plan.

Currently, there are 75 identified employees (including three executive officers, of which one is a director), four non-employee directors, and up to 75 other current or future staff members who would be eligible to receive stock options and/or shares of restricted stock under the 2021 Plan. Future new hires and additional non-employee directors and/or consultants would be eligible to participate in the 2021 Plan as well.

Stock Options

The 2021 Plan provides for either “incentive stock options” (“ISOs”), which are intended to meet the requirements for special federal income tax treatment under the Code, or “nonqualified stock options” (“NQSOs”). On May 12, 2021, the 2021 Plan was adopted by the board of directors and it was approved by the shareholders on July 15, 2021. Stock options may be granted on such terms and conditions as the Compensation Committee may determine; provided, however, that the per share exercise price under a stock option may not be less than the fair market value of a share of the Company’s Common Stock on the date of grant and the term of the stock option may not exceed 10 years (110% of such value and five years in the case of an ISO granted to an employee who owns (or is deemed to own) more than 10% of the total combined voting power of all classes of capital stock of the Company or a parent or subsidiary of the Company). ISOs may only be granted to employees. In addition, the aggregate fair market value of our Common Stock covered by one or more ISOs (determined at the time of grant) which are exercisable for the first time by an employee during any calendar year may not exceed $100,000. Any excess is treated as a NQSO.

Stock Appreciation Rights

An SAR entitles the participant, upon exercise, to receive an amount, in cash or stock or a combination thereof, equal to the increase in the fair market value of the underlying Common Stock between the date of grant and the date of exercise. SARs may be granted in tandem with, or independently of, stock options granted under the 2021 Plan. An SAR granted in tandem with a stock option (i) is exercisable only at such times, and to the extent, that the related stock option is exercisable in accordance with the procedure for exercise of the related stock option; (ii) terminates upon termination or exercise of the related stock option (likewise, the Common Stock option granted in tandem with a SAR terminates upon exercise of the SAR); (iii) is transferable only with the related stock option; and (iv) if the related stock option is an ISO, may be exercised only when the value of the stock subject to the stock option exceeds the exercise price of the stock option. An SAR that is not granted in tandem with a stock option is exercisable at such times as the Compensation Committee may specify.

Performance Share and Performance Unit Awards

Performance share and performance unit awards entitle the participant to receive cash or shares of our Common Stock upon the attainment of specified performance goals. In the case of performance units, the right to acquire the units is denominated in cash values.

Restricted Stock Awards and Restricted Stock Unit Awards

A restricted stock award is a grant or sale of Common Stock to the participant, subject to our right to repurchase all or part of the shares at their purchase price (or to require forfeiture of such shares if issued to the participant at no cost) in the event that conditions specified by the Compensation Committee in the award are not satisfied prior to the end of the time period during which the shares subject to the award may be repurchased by or forfeited to us. Our restricted stock unit entitles the participant to receive a cash payment equal to the fair market value of a share of Common Stock for each restricted stock unit subject to such restricted stock unit award, if the participant satisfies the applicable vesting requirement.

Unrestricted Stock Awards

An unrestricted stock award is a grant or sale of shares of our Common Stock to the participant that is not subject to transfer, forfeiture or other restrictions, in consideration for past services rendered to the Company or an affiliate or for other valid consideration.

Amendment and Termination

The Compensation Committee may adopt, amend and rescind rules relating to the administration of the 2021 Plan, and amend, suspend or terminate the 2021 Plan, but no such amendment, rescission, suspension or termination will be made that materially and adversely impairs the rights of any participant with respect to any award received thereby under the 2021 Plan without the participant’s consent, other than amendments that are necessary to permit the granting of awards in compliance with applicable laws.

The following table provides equity compensation plan information as of December 31, 2022:2023:

Employee Stock Purchase Plan

In the fourth quarter of 2022, the board of directors adopted an Employee Stock Purchase Plan (“ESPP”) which was effective as of January 1, 2023 with a term of 10 years. The ESPP allows eligible employees to purchase shares of the Company's common stock at a discounted price, through payroll deductions from a minimum of 1% and up to 25% of their eligible compensation up to a maximum of $25,000 or the IRS allowable limit per calendar year. The Company’s Chief Financial Officer administers the ESPP in conjunction with approvals from the Company’s Compensation Committee, including with respect to the frequency and duration of offering periods, the maximum number of shares that an eligible employee may purchase during an offering period, and, subject to certain limitations set forth in the ESPP, the per-share purchase price. Currently, the maximum number of shares that can be purchased by an eligible employee under the ESPP is 10,000 shares per offering period and there are two six-month offering periods that begin in the first and third quarters of each fiscal year. The purchase price for one share of Common Stock under the ESPP is currently equal to 85% of the fair market value of one share of Common Stock on the first trading day of the offering period or the purchase date, whichever is lower (look-back feature). Although not required by the ESPP, all payroll deductions received or held by the Company under the ESPP are segregated and deemed as “restricted cash” until the completion of the offering period and redemption of the applicable shares and those withheld amounts are recorded as liabilities. The maximum aggregate number of shares of the Common Stock that may be issued under the ESPP is 1,000,000 shares.

Under ASC 718-50 “Employee Share Purchase Plans” the plan is considered a compensatory plan and the compensation for each six-month offering period is computed based upon the grant date fair value of the estimated shares to be purchased based on the estimated payroll deduction withholdings. The grant date fair value was computed as the sum of (a) 15% purchase discount off of the grant date quoted trading price of the Company’s common stock and (b) the fair value of the look-back feature of the Company’s common stock on the grant date which consists of a call option on 85% of a share of common stock and a put option on 15% of a share of common stock.

In the year ended December 31, 2023, the Company issued 111,538 shares of common stock related to two transactions. For the six months ended June 30, 2023, the employee contributions for the first ESPP tranche totaled $117,048 and represented a purchase price of $1.79 per share for 65,561 shares. For the six-month period beginning July 1, 2023 and ending December 31, 2023 the employee contributions for the second ESPP tranche totaled $113,352 and represented a purchase price of $2.47 per share for 45,977 shares.

Item 13. Certain Relationships and Related Transactions, and Director Independence

On August 1, 2012, the Company entered into an independent contractor master services agreement (the “Services Agreement”) with Luceon, LLC, a Florida limited liability company, owned by our former Chief Technology Officer, David Ponevac. The Services Agreement provided that Luceon would provide support services including management, coordination or software development services and related services to duos. In January 2019, additional services were contracted with Luceon for TrueVue360™ primarily for software development through the provision of 7 additional full-time contractors located in Slovakia at a cost of $16,250 for January initially, rising to $25,583 after fully staffed, per month starting February 2019. This was in addition to the existing contract of $7,480 per month for duos for 4 full-time contractors which increased to $8,231 per month in June of 2019. During 2020 efforts in reducing cost, Luceon reduced its staff for the TrueVue360 software development team from a staff of 7 to 3 full-time employees at a cost of $11,666 per month starting June 1, 2020. As of January 1, 2021, the Company ceased recording activities in TrueVue360 nor its combined billings for a total of $20,986 per month. For the years ended December 31, 2022 and 2021, the total amount expensed was $0 and $93,422, respectively. The Company had no open accounts payable with Luceon at December 31, 2022 or 2021. On May 14, 2021, the Company formally ended its relationship with Luceon in concert with the resignation of our Chief Technology Officer and as such there is no longer a related party relationship.None
