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. The Company, based in Jacksonville, Florida, oversees its wholly owned subsidiary, duostech™ and employs approximately 75 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 Company 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 duos tech, 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 on staff and as consultants in the rail industry.

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 remote 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 seconds of the railcar passing through the RIP, a detailed report is sent to the customer where they are able to action identified issues. This solution has the potential to transform the railroad industry immediately 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. cen t raco® 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. true vue360™ 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 subsequently sold its iCAS assets to a buyer during the second quarter of 2023 for $165,000 via a convertible note.

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

| · | Introducing a new “subscription” based offering for access to data and images by a much broader target market including Class 1 railroads, railcar owners and lessors, and short-line railroads.

| · | Owning and operating a network of RIPs with multiple subscribers outside of the Company’s traditional customer base.

| · | Selling customized RIPs to Class 1, short-line and other industrial companies where specialized applications or routes demand a bespoke solution.

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. Currently the Company has a high-reliability catalog of over 35 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-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 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

| · | Improve our operational and technical execution, customer satisfaction and implementation speed.

| · | Expand Rail Inspection Portal and Automated Logistics Information System with current and future customers in Rail, Logistics and U.S. Government sectors.

| · | Offer both CAPEX (one-time sale) and Subscription pricing models that seek to increase recurring revenue and improve profitability.

| · | Form strategic partnerships that improve market access and credibility.

| · | Improve policy, processes, and toolsets to become a viable platform for internal growth and for mergers and acquisitions.

| · | Thoughtfully execute mergers and acquisitions to expand offerings and/or capabilities.

| · | Promote a performance-based work force where employees enjoy their work and are incentivized to excel and innovate.

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 September 2020 and has years of experience successfully leading start-up and turn-around companies. In addition, a key account executive from one of 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 of sales experience focused in the rail market. In 2021, the Company also hired a new Chief Technology Officer bringing 25 years of experience in designing and delivering 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 with 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, 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 2023 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.

5

Government Regulations

The Company has worked with various agencies of the federal government for more than 10 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 Agency (TSA) as well as the DHS previously mentioned. We expect to develop similar relationships with governmental agencies in target markets 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 75 employees, of which 67 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.

Recent Developments

On April 1, 2023, the Board granted to certain key employees an aggregate of 353,117 non-qualified stock options with a strike price of $4.22, a term of 5-years and 3-year vesting period. The options were granted prior to the certificates being issued subject to a pending modification of specific language contained within the option agreement pertaining to certain rights of the holder in the event of a merger or acquisition. The specific language was approved by the shareholders on May 17, 2023 after which the option certificates were issued with the modified language. The specific language had no bearing on the grant date nor on the valuation. Following the approval by the shareholders but prior to issuance of the certificates, one holder resigned from the Company and forfeited 60,000 unvested options leading to a net issuance during the quarter of 293,117 non-qualified stock options. The Company expects to take a charge of $567,569 during the vesting period.

As previously reported, on May 16, 2023 the Company held its 2023 annual meeting of stockholders. Certain matters were approved at the meeting including election of Board members, the issuance of shares of common stock upon conversion of shares of Series D Preferred Stock, approval of an Employee Stock Purchase Plan (ESPP), and ratification of the auditors.

On June 29, 2023, the Company announced that based on preliminary unaudited estimates as of that date, it expects total revenue for the second quarter of 2023 to be between $1.8 million and $2.1 million. The decrease is due to timing factors primarily related to the booking of revenues versus costs. Based on preliminary second quarter results, the Company expects total revenues for the six months ended June 30, 2023 to be approximately $4.5 million.

On July 6, 2023, the Company issued an aggregate of 5,645 shares of common stock for payment of board fees to three directors in the amount of $32,500 for services to the board which was expensed during the three months ended June 30, 2023.

RISK FACTORS

Investing in our securities involves a great deal of risk. Careful consideration should be made of the following factors as well as other information included in this prospectus 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. Our business, financial condition or operating results could be materially harmed by any of these risks. This could cause the trading price of our securities to decline, and you may lose all or part of your investment. Additional risks that we do not yet know of or that we currently think are immaterial may also affect our business and results of operations.

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 proposals 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.

16

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.

17

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 $55 million and $52 million as of March 31, 2023 and December 31, 2022, respectively. 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.

18

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.

19

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.

The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows:

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, a single customer accounted for 83% of revenues. For the three-months ended March 31, 2023, two customers accounted for 70% and 20% of revenues. For the three months ended March 31, 2022, four customers accounted for 35%, 24%, 13% and 11% 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.

At December 31, 2022, four customers accounted for 34%, 31%, 19% and 10% of accounts receivable. At December 31, 2021, two customers accounted for 81% and 10% of accounts receivable. As of March 31, 2023, three customers accounted for 59%, 15% and 11% of accounts receivable. At March 31, 2022, three customers accounted for 45%, 32% and 17% of accounts receivable. Much of the credit risk is mitigated since all the customers listed here are Class 1 railroads with a history of timely payments to us.

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% of our total revenues for the year ended December 31, 2022. 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:

| · | Variations in our quarterly operating results;
| · | Announcements that our revenue or income are below analysts’ expectations;
| · | General economic downturns;
| · | Sales of large blocks of our common stock; and
| · | Announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments.

You may experience dilution of your ownership interest due to future issuances 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 stockholder 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.

21

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

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

| · | Period-to-period fluctuations in financial results
| · | Issues in manufacturing products
| · | Unanticipated potential product liability claims
| · | The introduction of technological innovations or new commercial products by competitors
| · | The entry into, or termination of, key agreements, including key strategic alliance agreements
| · | The initiation of litigation to enforce or defend any of our intellectual property rights
| · | Regulatory changes
| · | Failure of any of our products to achieve commercial success

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.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements. Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. Forward-looking statements involve risks and uncertainties and include statements regarding, among other things, our projected revenue growth and profitability, our growth strategies and opportunity, anticipated trends in our market and our anticipated needs for working capital. They are generally identifiable by use of the words “may,” “will,” “should,” “anticipate,” “estimate,” “plans,” “potential,” “projects,” “continuing,” “ongoing,” “expects,” “management believes,” “we believe,” “we intend” or the negative of these words or other variations on these words or comparable terminology. These statements may be found under the sections entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business,” as well as in this prospectus generally. In particular, these include statements relating to future actions, prospective products, market acceptance, future performance or results of current and anticipated products, sales efforts, expenses, and the outcome of contingencies such as legal proceedings and financial results.

Examples of forward-looking statements in this prospectus include, but are not limited to, our expectations regarding our business strategy, business prospects, operating results, operating expenses, working capital, liquidity and capital expenditure requirements. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding demand for our products, the cost, terms and availability of components, pricing levels, the timing and cost of capital expenditures, competitive conditions and general economic conditions. These statements are based on our management’s expectations, beliefs and assumptions concerning future events affecting us, which in turn are based on currently available information. These assumptions could prove inaccurate. Although we believe that the estimates and projections reflected in the forward-looking statements are reasonable, our expectations may prove to be incorrect.

Important factors that could cause actual results to differ materially from the results and events anticipated or implied by such forward-looking statements include, but are not limited to:

| · | changes in the market acceptance of our products;
| · | increased levels of competition;
| · | changes in political, economic or regulatory conditions generally and in the markets in which we operate;
| · | our relationships with our key customers;
| · | our ability to retain and attract senior management and other key employees;
| · | our ability to quickly and effectively respond to new technological developments;
| · | our ability to protect our trade secrets or other proprietary rights, operate without infringing upon the proprietary rights of others and prevent others from infringing on the proprietary rights of the Company; and
| · | other risks, including those described in the “Risk Factors” discussion of this prospectus.

We operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for us to predict all of those risks, nor can we assess the impact of all of those risks on our business or the extent to which any factor may cause actual results to differ materially from those contained in any forward-looking statement. The forward-looking statements in this prospectus are based on assumptions management believes are reasonable. However, due to the uncertainties associated with forward-looking statements, you should not place undue reliance on any forward-looking statements. Further, forward-looking statements speak only as of the date they are made, and unless required by law, we expressly disclaim any obligation or undertaking to publicly update any of them in light of new information, future events, or otherwise.

USE OF PROCEEDS

We will not receive any proceeds from the sale of common stock by the Selling Stockholders. All of the net proceeds from the sale of our common stock will go to the Selling Stockholders as described below in the sections entitled “Selling Stockholders” and “Plan of Distribution”. We have agreed to bear the expenses relating to the registration of the common stock for the Selling Stockholders.

24

SELLING STOCKHOLDERS

On March 27, 2023, the Company entered into a Security Purchase Agreement with the Selling Stockholders, pursuant to which the Selling Stockholders purchased 4,000 shares of a newly authorized Series E Preferred Stock. The Company received proceeds of $4,000,000. The Series E Preferred Stock is convertible into Common Stock at $3.00 a share. If all of the shares of the outstanding Series E Preferred Stock are converted in full, the Company would issue 1,333,334 shares of Common Stock.

The shares of common stock being offered by the Selling Stockholders are those issuable to the Selling Stockholders, upon conversion of the Series E Preferred Stock. We are registering the shares of common stock in order to permit the Selling Stockholders to offer the shares for resale from time to time. Due to the ownership of the shares of Series E Preferred Stock, as well as ownership of common stock, Series D Preferred Stock and warrants, the Selling Stockholders collectively have had a material relationship with us within the past three years and hold the largest percentage ownership of the Company subject to certain limitations as described in the offering.

The table below lists the Selling Stockholders and other information regarding the beneficial ownership of the shares of Common Stock by each of the Selling Stockholders. The first column lists the number of shares of Common Stock beneficially owned by each Selling Stockholder as of June 30, 2023, assuming exercise of the Series E Preferred Stock, as well as conversion of other convertible preferred stock and exercise of any warrants held by the Selling Stockholders on that date. The third column lists the shares of Common Stock being offered by this prospectus by the Selling Stockholders.

In accordance with the terms of a registration rights agreement with the Selling Stockholders, this prospectus generally covers the resale of the maximum number of shares of common stock issuable upon conversion of the Series E Preferred Stock, determined as if the outstanding shares of Series E Preferred Stock were converted in full as of the trading day immediately preceding the applicable date of determination and subject to adjustment as provided in the registration rights agreement, without regard to any limitations on the conversion of the Series E Preferred Stock. The fourth column assumes the sale of all of the shares offered by the Selling Stockholders pursuant to this prospectus.

25

Under the terms of the Series E Preferred Certificate of Designation, certain previously held warrants and the Series D Preferred Certificate of Designation, a Selling Stockholder may not exercise the warrants or convert the Series B Preferred Stock or the Series E Preferred Stock to the extent such exercise or conversion would cause such Selling Stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed 19.99% of our then outstanding common stock following such exercise or conversion, excluding for purposes of such determination shares of common stock issuable upon exercise of the warrants which have not been exercised and shares of common stock issuable upon conversion of the preferred stock which has not been converted. The number of shares in the second column does not reflect this limitation. The Selling Stockholders may sell all, some, or none of their shares in this offering. See “Plan of Distribution.”

———————

(1) | The actual number of shares of Common Stock offered hereby and included in the registration statement of which this prospectus is a part includes, in accordance with Rule 416 under the Securities Act, such indeterminate number of additional shares of our Common Stock as may become issuable in connection with any proportionate adjustment for any stock splits, stock combinations, stock dividends, recapitalizations, anti-dilution adjustments or similar events with respect to our Common Stock.
(2) | Based on Amendment No. 6 to Schedule 13G/A filed by Bleichroeder LP (“Bleichroeder”) with the SEC on February 14, 2023 (the “Bleichroeder 13G/A”). According to the Bleichroeder 13G/A, Bleichroeder is an investment advisor registered under Section 203 of the Investment Advisers Act of 1940 and as of February 14, 2023 was deemed to be the beneficial owner of 1,283,162 shares of our Common Stock as a result of acting as investment advisor to various clients. The number of shares beneficially owned by Bleichroeder does not include warrants to purchase shares of our Common Stock held of record by 21 April Fund, Ltd. in the amount of 32,724 or warrants to purchase shares of our Common Stock held of record by 21 April Fund LP (together with 21 April Fund, Ltd., the “21 April Entities”) in the amount of 11,920 due to a 9.99% beneficial ownership limitation included in such warrants. Bleichroeder acts as an investment advisor to the 21 April Entities. The 21 April Entities also purchased 999 shares of Series D Preferred Stock on September 30, 2022, which is convertible into 333,000 shares of Common Stock, and excluded from the above calculations. The 21 April Entities also purchased 4,000 shares of Series E Preferred Stock on March 27, 2023, which is convertible into 1,333,334 shares of Common Stock and included in the calculations above.

PLAN OF DISTRIBUTION

Each Selling Stockholder of the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

| · | ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
| · | block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;
| · | purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
| · | an exchange distribution in accordance with the rules of the applicable exchange;
| · | privately negotiated transactions;
| · | through one or more underwritten offerings on a firm commitment or best efforts basis;
| · | settlement of short sales that are not in violation of Regulation SHO;
| · | in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;
| · | through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
| · | through the distribution of securities by any Selling Stockholder to its parents, members or security holders;
| · | a combination of any such methods of sale; or
| · | any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus. The Selling Stockholders have the sole and absolute discretion not to accept any purchase offer or make any sale of securities if they deem the purchase price to be unsatisfactory at any particular time.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM- 2440.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders may from time to time pledge or grant a security interest in some or all of their securities to their broker-dealers under the margin provisions of customer agreements or to other parties to secure other obligations. If a Selling Stockholder defaults on a margin loan or other secured obligation, the broker-dealer or secured party may, from time to time, offer and sell the securities pledged or secured thereby pursuant to this prospectus. The Selling Stockholders and any other persons participating in the sale or distribution of the securities will be subject to applicable provisions of the Securities Act and the Exchange Act, and the rules and regulations thereunder, including, without limitation, Regulation M. These provisions may restrict certain activities of, and limit the timing of purchases and sales of any of the securities by, the Selling Stockholders or any other person, which limitations may affect the marketability of the securities.

The Selling Stockholders also may transfer the shares of our securities in other circumstances, in which case the transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

27

A Selling Stockholder that is an entity may elect to make a pro rata in-kind distribution of securities to its members, partners or shareholders pursuant to the registration statement of which this prospectus is part by delivering a prospectus. To the extent that such members, partners or shareholders are not affiliates of ours, such members, partners or shareholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement.

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

MANAGEMENT’S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Registration Statement on Form S-1 and other reports filed by the Company from time to time with the SEC (collectively, the “Filings”) contain or may contain forward-looking statements and information that are based upon beliefs of, and information currently available to, the Company’s management as well as estimates and assumptions made by Company’s management. Readers are cautioned not to place undue reliance on these forward-looking statements, which are only predictions and speak only as of the date hereof. When used in the Filings, the words “anticipate,” “believe,” “estimate,” “expect,” “future,” “intend,” “plan,” or the negative of these terms and similar expressions as they relate to the Company or the Company’s management identify forward-looking statements. Such statements reflect the current view of the Company with respect to future events and are subject to risks, uncertainties, assumptions, and other factors, including the risks relating to the Company’s business, industry, and the Company’s operations and results of operations. Should one or more of these risks or uncertainties materialize, or should the underlying assumptions prove incorrect, actual results may differ significantly from those anticipated, believed, estimated, expected, intended, or planned.

Although the Company believes that the expectations reflected in the forward-looking statements are reasonable, the Company cannot guarantee future results, levels of activity, performance, or achievements. Except as required by applicable law, including the securities laws of the United States, the Company does not intend to update any of the forward-looking statements to conform these statements to actual results.

Our financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions upon which we rely are reasonable based upon information available to us at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the reported amounts of revenues and expenses during the periods presented. Our financial statements would be affected to the extent there are material differences between these estimates and actual results. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management’s judgment in its application. There are also areas in which management’s judgment in selecting any available alternative would not produce a materially different result. The following discussion should be read in conjunction with our financial statements and notes thereto appearing elsewhere in this Registration Statement on Form S-1.

Overview

We intend for this discussion to provide information that will assist in understanding our financial statements, the changes in certain key items in those financial statements, and the primary factors that accounted for those changes, as well as how certain accounting principles affect our financial statements.

Our Company

The Company was incorporated in Florida on May 31, 1994 under the original name of Information Systems Associates, Inc. Initially, our 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, the Company entered negotiations with Duos Technologies, Inc. (“Duos”), for the purposes of executing a reverse triangular merger. This transaction was completed on April 1, 2015, whereby Duos became a wholly owned subsidiary of the Company. Duos was incorporated under the laws of Florida on November 30, 1990 for design, development and deployment of proprietary technology applications and turn-key engineered systems. The Company, based in Jacksonville, Florida, has a current staff of 76 people of which 69 are full-time, and is a technology and software applications company with a strong portfolio of intellectual property. The Company’s core competencies, including advanced intelligent technologies, are delivered through its proprietary integrated enterprise command and control platform, Centraco®.

30

The Company has developed the Rail Inspection Portal (“RIP”) which provides both freight and transit railroad customers and select government agencies the ability to conduct fully remote railcar inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination and other sensors, scans each passing railcar to create a high-resolution image set from a variety of angles including the undercarriage. These images are then processed through various methods of artificial intelligence algorithms to identify specific defects and/or areas of interest on each railcar. This is all accomplished within seconds of a railcar passing through our portal. We believe this solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The Company has deployed this system with several Class 1 railroad customers and anticipates an increased demand from transit and other railroad customers along with selected government agencies that operate and/or manage rail traffic in the future. Government agencies can conduct digital inspections combined with the incorporated artificial intelligence (“AI”) to improve rail traffic flow across borders which also directly benefits the Class 1 railroads through increasing their velocity.

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 also incorporates sensors and data points as necessary for each operation and directly interconnects with backend logistics databases and processes to streamline operations, and significantly improve operations and security and importantly dramatically improves the vehicle throughput on each lane on which the technology is deployed.

The Company has built a portfolio of IP and patented solutions that creates “actionable intelligence” using two core native platforms called Centraco and Praesidium™. All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface for all our systems as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various image capture devices and some sensors for input into the Centraco software.

The Company also developed a proprietary Artificial Intelligence software platform, Truevue360™ with the objective of focusing the Company’s advanced intelligent technologies in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.

The Company previously provided professional and consulting services for large data centers and had developed a system for the automation of asset information marketed as DcVue™. The Company deployed its DcVue software at one beta site. This software was used by Duos’ consulting auditing teams. DcVue was based upon the Company’s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed software product. The Company ceased offering this product in 2021.

The Company’s strategy is to deliver operational and technical excellence to our customers; expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics and U.S. Government Sectors; offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and improves profitability; responsibly grow the business both organically and through selective acquisitions; and promote a performance-based work force where employees enjoy their work and are incentivized to excel and remain with the Company.

In late 2022, the Company announced it will pursue a subscription platform for the Railcar Inspection Portals. 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.

31

Prospects and Outlook

The Company’s focus is to improve operational and technical execution which, we believe, will in turn enable the commercial side of the business to expand RIP and ALIS delivery into existing customers and to expand and diversify our current customer base. Even though the lingering effects of COVID-19 is expected to still be an issue during the remainder of 2023 the Company’s primary customers have indicated readiness to order more equipment and services should the Company execute as expected on key deliverables.

Additionally, the Company is making engineering and software upgrades to the RIP to meet anticipated Federal Railroad Association (FRA) and Association of American Railroad (AAR) standards. Similar upgrades are also being developed to improve the ALIS system. These upgrades will continue to be released throughout 2023 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 was awarded a large, multi-year contract with a national rail carrier. The Company anticipates that it will manufacture a two-RIP solution for the carrier in 2023 and, along with a long-term services agreement, complete delivery during the latter half of 2023.

Although the Company’s prospects and outlook are anticipated to be favorable for the remainder of 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. See “Risk Factors”.

The substantial increase in overall revenues for the quarter ended March 31, 2023 compared to the quarter ended March 31, 2022, is primarily related to the production and manufacturing of new and upgraded RIPs which are recorded in the technology systems portion of our business as compared to being in the very early stages of developing two portals during the first quarter of 2022. We expect this trend to continue through 2023, although supply chain issues have continued to extend deadlines for shipment of key components used in our technology systems and continue to pose a risk to the timing of revenue recognition. Given recent attention and renewed focus around railway safety, the Management team remains optimistic about the long-term outlook of the Company. We believe the focus on rail safety will prompt additional government oversight on railroads for the implementation of safety systems such as the Company’s RIP product. Additionally, the Company sees opportunities to continue to expand its programs with existing customers during the current year and beyond. Management cautions that, in spite of a positive outlook, the noted slowing of the supply chain coupled with a longer commercial cycle may result in revenue recognition pushing into 2024. The Company remains focused on revenue and margins performance impacts from inflation and continued supply chain challenges and proactively works to address these issues via customer pricing.

The growth of the services portion of revenues is driven by the successful completion and implementation of artificial intelligence detections and represents services and support for those detections. The growth in services revenue is also bolstered by the phasing in of services and maintenance agreements related to new portals coming online during early 2023. The Company expects growth with new revenue from existing customers, including services revenue as the result of new maintenance contracts being established on installations coming on-line during 2023. The Company also anticipates renewals of existing and backlog contracts and a shift to the next generation of technology systems which are currently being manufactured and completed during 2023.

Cost of revenues: |  |  |  |  |  |  |  |  |
Technology systems |  | $ | 1,767,209 |  |  | $ | 865,488 |  |  |  | 104 | %
Services and consulting |  |  | 339,907 |  |  |  | 351,762 |  |  |  | -3 | %
Total cost of revenues |  | $ | 2,107,116 |  |  | $ | 1,217,250 |  |  |  | 73 | %

Cost of revenues largely comprises equipment and labor necessary to support the implementation of new systems and support and maintenance of existing systems and software projects.

Cost of revenues on technology systems increased during the three months ended March 31, 2023 over the equivalent period in 2022, in a manner consistent with the increase in revenues and as a result of additional project works ongoing for the Company. In the second quarter of 2022, the Company was awarded two high-speed Rail Inspection Portals for its passenger transit client and by the first quarter of 2023 has phased into the manufacture of these two more expensive and more robust transit-oriented RIPs. By comparison, during the first quarter ended March 31, 2022, the Company had only begun to procure the components for, and the manufacturing of, these two transit-oriented RIPs, thereby contributing to the increase in cost of revenues year-over-year. The Company also continues to face headwinds with supply disruption and cost. While we expect that macro-economic factors will continue to drive prices, the Company continues to manage its costs and, where possible, pass through increased costs to customers in the form of higher prices, although this is not assured.

Cost of revenues on services and consulting slightly decreased in the three months ended March 31, 2023 compared to the prior year period. The cost of revenues decreased as compared to an increase in services revenues. This misalignment in the change between the two is a result of high margin artificial intelligence detections entering service and boosting revenue while the overall cost structure to implement these charges is largely unchanged and partially captured in the capitalization of software development costs.

Gross margin showed a significant improvement for the first quarter of 2023 as compared to the same period in 2022. As noted above, the improvement in margin was a direct result of increased business activity the Company recognized in the first quarter of 2023 related to the manufacturing of two high-speed, transit-focused Rail Inspection Portals for one customer. The Company began to recognize revenue and profit on those activities in conformity with its revenue recognition policy during late 2022 and which continued into the first quarter of 2023. The recognition of the revenue and subsequent profit from this major project yielded the higher gross margins of approximately 20% for the period. By comparison in the first quarter of 2022, the Company had only initiated procurement and some manufacturing for two freight-oriented RIPs for two customers and as a result recognized no profit on the works resulting in a dilutive, low margin for the period. It should be noted that when comparing the results between two periods, the stage of completion for manufacturing and installation can factor into those comparisons and should be taken into account when analyzing those periods.

Operating Expenses

|  | For the Three Months Ended |
|  | March 31, |
|  | 2023 |  |  | 2022 |  |  | % Change |
Operating expenses: |  |  |  |  |  |  |  |  |  |  |  |
Sales and marketing |  | $ | 307,577 |  |  | $ | 283,894 |  |  |  | 8 | %
Research and development |  |  | 404,885 |  |  |  | 436,717 |  |  |  | -7 | %
General and administration |  |  | 1,971,508 |  |  |  | 2,143,073 |  |  |  | -8 | %
Total operating expenses |  | $ | 2,683,970 |  |  | $ | 2,863,684 |  |  |  | -6 | %

Overall operating expenses during the three months ended March 31, 2023 were marginally lower compared to the equivalent period in 2022. The Company saw only slight increase in cost for sales and marketing as a result of an increased commercial team with a larger decrease in general and administration and research and development costs during the same period for 2023 partially attributable to the Company’s reduced non-cash compensation charges for staff. Overall, the Company continues to focus on stabilizing operating expenses while meeting the increased needs of our customers.

Loss from Operations

The loss from operations for the three months ended March 31, 2023 and 2022 was $2,146,798 and $2,641,618, respectively. The decrease in loss from operations was primarily the result of higher revenues recorded in the quarter resulting from increases in both our technology systems and services and consulting, slower growth in costs of those revenues and flat operating expenses.

Other Income/Expense

Other income for the three months ended March 31, 2023 was $4,295 and $182 for the comparative period in 2022. Interest expense for the three months ended March 31, 2023 was $1,180 and $3,180 for the comparative period in 2022.

Net Loss

The net loss for the three months ended March 31, 2023 and 2022 was $2,143,683 and $2,644,616, respectively. The 19% decrease in net loss was mostly attributed to the increase in revenues as described above along with slower growing expenses. Net loss per common share was $0.30 and $0.49 for the three months ended March 31, 2023 and 2022, respectively.

Liquidity and Capital Resources

As of March 31, 2023, the Company has a working capital surplus of $3,860,339 and the Company had a net loss of $2,143,683 for the three months ended March 31, 2023.

Cash Flows

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

|  | For the Three Months Ended March 31, |
|  | 2023 |  |  | 2022 |
Net cash used in operating activities |  | $ | (7,086 | ) |  | $ | (827,733 | )
Net cash used in investing activities |  |  | (261,144 | ) |  |  | (102,078 | )
Net cash provided by financing activities |  |  | 3,488,085 |  |  |  | 5,365,954 |
Net increase in cash |  | $ | 3,219,855 |  |  | $ | 4,436,143 |

Net cash used in operating activities for the three months ended March 31, 2023 and 2022 was $7,086 and $827,733, respectively. The decrease in net cash used in operations for the three months ended March 31, 2023 was the result of cash inflows from new projects offset by cash outflows to procure necessary materials and overall sales, general and administrative expenses. In addition, there are several changes in assets and liabilities compared to the previous period that decreased the use of cash in operations, notably the change in contract liabilities due to the timing of project invoicing milestones and cash receipts.

Net cash used in investing activities for the three months ended March 31, 2023 and 2022 was $261,144 and $102,078, respectively, representing an increase in the purchase of various fixed assets for computer equipment and product and software development.

Net cash provided by financing activities for the three months ended March 31, 2023, and 2022 was $3,488,085 and $5,365,954, respectively. Cash flows provided by financing activities during the first three months of 2023 were primarily attributable to net proceeds of approximately $4,000,000 from issuances of Series E Convertible Preferred Stock. Cash flows from financing activities during the first three months of 2022 were primarily attributable to the issuance of common stock for $6,095,000 of gross proceeds.

On a long-term basis, our liquidity is dependent on continuation and expansion of operations and receipt of revenues. We believe our current capital and revenues are sufficient to fund such expansion and our operations over the next twelve months, although we are dependent on timely payments from 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. The Company may elect to purchase materials and supplies in advance of contract award but where there is a high probability of that award.

Demand for our 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. Because a major portion of our activities is the receipt of revenues from the sales of our products and services, our business operations may continue to be challenged by our competitors and prolonged recession periods.

Liquidity

As reflected in the accompanying consolidated financial statements, the Company had a net loss of $2,143,683 for the three months ended March 31, 2023. During the same period, cash used in operating activities was $7,086. The working capital surplus and accumulated deficit as of March 31, 2023, were $3,860,339 and $54,505,517, 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 offering and private placements which were completed during 2022 as well as the first quarter of 2023.

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 2022 in raising gross proceeds of over $10,100,000 from the sale of both common shares and Series E Preferred Stock across the year. Additionally, late in the first quarter of 2023, the Company raised gross proceeds of $4,000,000 from the issuance of Series E Preferred Stock (See Note 12). As part of its strategy, the Company will endeavor to utilize the Series E Preferred and the remainder of the Series E Preferred Stock as additional funding mechanisms. Additionally, during the second quarter of 2023, 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 affect 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 delays or inflationary increases and its effects on our customers in the coming quarters. 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 12 months from the date of this prospectus.

35

In addition, management has been taking 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, as described above, it will have sufficient sources of 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 positive signs from new commercial engagements that indicate improvements in future commercial opportunities.

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, improvements in the commercial outlook, 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 with the benefit of potential tailwinds from renewed awareness around railroad safety. 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 2023 and beyond. As a result, we expect to generate sufficient revenue and to attain profitable operations with less net cash used in operating activities in the next 12 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 Policies and Estimates

We have identified the accounting policies below as critical to our business operations and the understanding of our results of operations.

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.

Stock-Based Compensation

The Company accounts for employee stock-based compensation in accordance with ASC 718-10, “Share-Based Payment,” which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options, restricted stock units, and employee stock purchases based on estimated fair values.

The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The Company’s determination of fair value 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.

36

Revenue Recognition and Contract Accounting

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 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 our 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 revenue from four sources: (1) Technology Systems; (2) AI Technologies; (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 now bases its 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 indirect 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.

Artificial Intelligence

The Company has revenue from applications that incorporate artificial intelligence (AI) in the form of predetermined algorithms which provide important operating information to the users of our systems. The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue at a point in time upon 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 term of the contract.

37

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 the financial statements included in this prospectus, 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 the 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.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues and the total estimated costs to determine progress towards contract completion, valuation of inventory, estimates of the valuation of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt, and valuation of stock-based awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Results of Operations

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

For the year ended December 31, 2022 compared to December 31, 2021

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 Years Ended |
|  | December 31, |
|  | 2022 |  |  | 2021 |  |  | % Change |
Revenues: |  |  |  |  |  |  |  |  |
Technology systems |  | $ | 11,190,292 |  |  | $ | 5,871,666 |  |  |  | 91 | %
Services and consulting |  |  | 3,822,074 |  |  |  | 2,388,251 |  |  |  | 60 | %
Total revenues |  | $ | 15,012,366 |  |  | $ | 8,259,917 |  |  |  | 82 | %

For the full year 2022, there was an 82% overall increase in revenues compared to 2021. The increase was driven by new revenues being recorded after lengthy delays in receiving “notices to proceed” for anticipated new contracts earlier in the year that pushed delivery dates into the second half of 2022 and into 2023. There was a significant 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 from the Company’s success in deploying artificial intelligence as well as change orders to existing services agreements during the year. 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 2023 and beyond. As previously discussed, 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. 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.

The Company’s capital structure continues to allow us to weather the unexpected delays without significant operational impact and enables us to pursue large projects where the ability to deploy major resources is required. 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 yield benefits 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 lags the Company has faced post-Covid-19. The Company continues to monitor the situation and procures materials ahead of contract award where feasible.

39

The Company also expects to continue the growth with new 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 revenues and this growth is expected to continue going forward. The Company expects to continue the growth with new, long term recurring revenue from existing customers which will be coming on-line in the next several months.

Cost of Revenues

|  | For the Years Ended |
|  | December 31, |
|  | 2022 |  |  | 2021 |  |  | % Change |
Cost of revenues: |  |  |  |  |  |  |  |  |
Technology systems |  | $ | 8,376,649 |  |  | $ | 4,728,197 |  |  |  | 77 | %
Services and consulting |  |  | 1,887,614 |  |  |  | 1,492,176 |  |  |  | 27 | %
Total cost of revenues |  | $ | 10,264,263 |  |  | $ | 6,220,373 |  |  |  | 65 | %

Cost of revenues largely comprises equipment, labor and overhead necessary to support the implementation of new systems and support and maintenance of existing systems. Cost of revenues on technology systems increased during the period compared to the equivalent period in 2021 by a slightly lower rate than the increase in revenues. The primary reason for the increased growth in costs year-over-year stems from additional project work related to the delivery of two Railcar Inspection Portals. Additionally, the Company made significant progress on the manufacturing of a special-purpose, high value Railcar Inspection Portal 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.

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. In concert with this, there is a continued focus on construction costs and savings through efficiency, but the Company has elected to expand its key employees in anticipation of expected sales growth in technology systems and services in 2023 and beyond.

Cost of revenues increased on services and consulting year-over-year albeit at a slower pace than the increase in services and consulting revenues. The increase in costs was a result of one-time services completed on existing RIP sites on which 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 increase in costs which is a positive trend. The Company 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 showed a significant improvement for the year ended December 31, 2022 as compared to the same period in 2021. As noted above, the improvement in margin was a direct result of increased business activity the Company recognized in the latter half of 2022. The increased business activity was related to the 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. The Company began to recognize revenue and profit on those activities in accord with its revenue recognition policy. 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% increase in revenue from additional projects and services drove an overall higher gross margin-dollar amount.

Operating Expenses

|  | For the Years Ended |
|  | December 31, |
|  | 2022 |  |  | 2021 |  |  | % Change |
Operating expenses: |  |  |  |  |  |  |  |  |  |  |  |
Sales and marketing |  | $ | 1,337,186 |  |  | $ | 1,233,851 |  |  |  | 8 | %
Research and development |  |  | 1,651,064 |  |  |  | 2,515,630 |  |  |  | -34 | %
General and Administration |  |  | 8,625,002 |  |  |  | 5,747,014 |  |  |  | 50 | %
Total operating expense |  | $ | 11,613,252 |  |  | $ | 9,496,495 |  |  |  | 22 | %

Overall operating expenses were higher by 22% in 2022 as compared to the full-year 2021. There was a marginal 8% increase in sales and marketing related to increased investment into the overall capability of the commercial team. Specifically, 2022 saw the Company bring in additional talent with direct experience from the technology and rail spaces. Research and development costs declined 34% during the year. This was 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 led to the Company performing additional project and one-time services work year-over-year. The offset of these charges reside in the cost of sales services and consulting. Additionally, general and administration costs increased approximately 50% because of 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. The Company still faces some pressure on existing staff compensation as a result of inflation during 2022 but remains focused to manage and stabilize administrative costs without interruption to customer service.

Loss From Operations

The losses from operations for the years ended, December 31, 2022 and 2021 were $6,865,149 and $7,456,951, respectively. The decrease in losses from operations during the year was the result of mostly improved 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 projects as well as an increase in services and consulting revenue increases and related margins outpaced the Company’s increased general and administrative costs throughout 2022. As a result, the Company achieved near breakeven in the fourth quarter of 2022. The Company has continued to face inflation and supply chain pressures during 2022 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, 2022 and 2021 was $9,191 and $20,268, respectively. The reduction in interest expense was primarily due to the financing charges related to insurance policies in 2021.

Other Income

Other income for the years ended December 31, 2022 and 2021 was $9,557 and $1,468,318, respectively. The decrease is mainly due to the PPP loan forgiveness recorded in the first quarter of 2021.

41

Net Loss

The net loss for the years ended December 31, 2022 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 gain in the first half of 2021. Despite the increased net loss year-over-year, the Company showed an improvement at the operating loss level. Net loss per common share was $1.11 and $1.63 for the years ended December 31, 2022 and 2021, respectively.

Liquidity and Capital Resources

As of December 31, 2022, the Company has a cash balance of $1,121,092.

Cash Flows

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

|  | For the Years Ended |
|  | December 31, |
|  | 2022 |  |  | 2021 |
Net cash used in operating activities |  | $ | (7,873,307 | ) |  | $ | (6,579,378 | )
Net cash used in investing activities |  |  | (644,888 | ) |  |  | (552,940 | )
Net cash provided in financing activities |  |  | 8,745,567 |  |  |  | 4,056,938 |
Net increase (decrease) in cash |  | $ | 227,372 |  |  | $ | (3,075,380 | )

Net cash used in operating activities for the years ended December 31, 2022 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, 2022 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. In addition, there are several changes in assets and liabilities that increased the use of cash in operations including increases in inventory for some long-lead components 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.

Net cash used in investing activities for the years ended December 31, 2022 and 2021 was $644,888 and $552,940, respectively. The Company continues to invest in computing, lab equipment and software and artificial development as reflected in the increase in 2022.

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

During 2022, 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, we have cash on hand of approximately $4,500,000. 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.

42

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 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 for the year ended December 31, 2022. During the same period, cash used in operating activities was $7,873,307. The working capital surplus and accumulated deficit as of December 31, 2022, were $2,339,052 and $52,361,834, 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 placement which were completed during the first quarter of 2022 and during third and fourth quarters of 2022 as well as the first quarter of 2023.

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 2022 in raising gross proceeds of over $10,100,000 from the sale of both common shares and Series E Preferred Stock. Additionally, late in the first quarter of 2023, the Company raised gross proceeds of $4,000,000 from the issuance of Series E Preferred Stock (See Note 16). As part of its strategy, the Company will endeavor to utilize the Preferred Series E and the remainder of the Series E as additional funding mechanisms. Additionally, during the second quarter of 2023, 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 affect 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. 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 12 months from the date of this prospectus.

In addition, management has been taking 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 Series E Preferred Stock offering coupled with an S-3 shelf registration availability starting in the second quarter of 2023, 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 positive signs from new commercial engagements that indicate improvements in future commercial opportunities.

43

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 2023 and beyond. As a result, we expect to generate sufficient revenue and to attain profitable operations with minimal cash use in the next 12 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.

Off Balance Sheet Arrangements

We have no-off balance sheet contractual arrangements, as that term is defined in Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies and Estimates

We have identified the accounting policies below as critical to our business operations and the understanding of our results of operations.

Revenue Recognition and Contract Accounting

The Company generates revenue from four sources: (1) Technology Systems; (2) AI Technology which is included in the consolidated statements of operations line-item Technology systems; (3) Technical Support; and (4) Consulting Services which is included in the consolidated statements of operations line-item Services and consulting.

Technology Systems

The Company constructs intelligent technology systems consisting of materials and labor under customer contracts. Revenues and related costs on technology systems revenue are recognized based 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.

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.

A contract is considered complete when all costs except insignificant items have been incurred and the installation is operating according to specifications or has been accepted by the customer.

The Company has contracts in various stages of completion. Such contracts require estimates to determine the appropriate cost and revenue recognition. Cost estimates are reviewed periodically on a contract-by-contract basis throughout the life of the contract such that adjustments to the profit resulting from revisions are made cumulative to the date of the revision. Significant management judgments and estimates, including the estimated costs to complete projects, must be made and used in connection with the revenue recognized in the accounting period. Current estimates may be revised as additional information becomes available.

44

Artificial Intelligence

The Company has revenue from applications that incorporate artificial intelligence (AI) in the form of predetermined algorithms which provide important operating information to the users of our systems. The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue at a point in time upon acceptance, as well as an annual application maintenance fee, which revenue is recognized ratably over the contracted maintenance term.

Technical Support

Maintenance and 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 term of the contract.

For sales arrangements that do not involve multiple performance obligations such as professional services, which are of short-term duration, revenues are recognized when services are completed.

Consulting Services

The Company’s consulting services business generates revenues under contracts with customers from three sources: (1) Professional Services (consulting and auditing); (2) Software licensing with optional hardware sales; and (3) Customer Service (training and 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 the financial statements included in this prospectus, 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 at a point in time 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 at a point in time 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 time ratably over the contract term.

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.

Share-Based Compensation

The Company accounts for employee and non-employee stock-based compensation in accordance with ASC 718-10, “Share-Based Payment,” which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options, restricted stock units, and employee stock purchases based on estimated fair values.

The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The Company’s determination of fair value 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.

45

Long-Lived Assets

The Company evaluates the recoverability of its property, equipment, and other long-lived assets 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 in the event the net book value of such assets exceed the estimated future undiscounted cash flows attributable 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 exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. The most significant estimates in the accompanying audited consolidated financial statements include the allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues and the total estimated costs to determine progress towards contract completion, valuation of inventory, estimates of the valuation of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt, and valuation of stock-based awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

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. The Company, based in Jacksonville, Florida, oversees its wholly owned subsidiary, duostech™ and employs approximately 75 people and is a technology company which designs, develops, deploys and operates intelligent technology solutions with a focus on software applications and AI. The Company 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 duos tech®, designs, develops and deploys technology 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 on staff and consultants in the rail industry.

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 remote 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 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 seconds of the railcar passing through the RIP, a detailed report is sent to the customer where they are able to action identified issues. This solution has the potential to transform the railroad industry by 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. cen t raco® 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. true vue360™ is our fully integrated platform that we utilize to develop and deploy AI algorithms, including Machine Learning, Computer Vision, Object Detection and Deep Neural Network-based processing for real-time applications.

47

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 subsequently sold its iCAS assets to a buyer during the second quarter of 2023 for $165,000 via a convertible note.

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

| · | Introducing a new “subscription” based offering for access to data and images by a much broader target market including Class 1 railroads, railcar owners and lessors, short line railroads.

| · | Owning and operating a network of RIPs with multiple subscribers outside of the Company’s traditional customer base.

| · | Selling customized RIPs to Class 1, Short-line and other industrial companies where specialized applications or routes demand a bespoke solution.

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 are using 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. Currently, the Company has a high-reliability catalog of over 35 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. Because of our early leadership position, we have been able to accumulate experience and intellectual property that we believe would be time-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 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 have 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 into 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

| • | Improve our operational and technical execution, customer satisfaction and implementation speed.

| • | Expand Rail Inspection Portal and Automated Logistics Information System with current and future customers in Rail, Logistics and U.S. Government sectors.

| • | Offer both CAPEX (one-time sale) and Subscription pricing models that seek to increase recurring revenue and improve profitability.

| • | Form strategic partnerships that improve market access and credibility.

| • | Improve policy, processes, and toolsets to become a viable platform for internal growth and for mergers and acquisitions.

| • | Thoughtfully execute mergers and acquisitions to expand offerings and/or capabilities.

| • | Promote a performance-based work force where employees enjoy their work and are incentivized to excel and innovate.

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 2020 and has years of experience successfully leading start-up and turn-around companies. In addition, a key account executive from one of 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 of sales experience focused in the rail market. 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 brings 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 customers. Even though supply chain issues are expected to continue through 2023, 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.

50

For 2023 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 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 continually review potential changes in the regulatory environment and maintain contact with key personnel at certain agencies including the Federal Railroad Administration (FRA), Transportation Safety Agency (TSA) as well as the DHS previously mentioned. We expect to develop similar relationships with governmental agencies in target markets both in the US and internationally. At this time, we believe our offerings are complementary with 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 75 employees of which 67 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.

Properties

On July 26, 2021, as amended on November 24, 2021, the Company entered into a new operating lease agreement for office and warehouse combination space of 40,000 square feet with the lease commencing on November 1, 2021 and ending May 31, 2032. This additional space allows for resource growth and engineering efforts for operations before deploying to the field. The rent for the first 12 months of the term was calculated as rentable base space on 30,000 square feet. The rent is subject to an annual escalation of 2.5%, beginning December 1, 2022. The Company made a security deposit payment in the amount of $600,000 on July 26, 2021. The Company has applied the FASB issued ASU No. 2016-02 Leases (Topic 842) (“ASU 2016-02”) in the fourth quarter of 2021.

The Company now has a total of office and warehouse space of 40,000 square feet.

Rental expense for the office lease during 2022 and 2021 was $782,591 and $414,085, respectively.

Legal Proceedings

From time to time, we may be involved in litigation relating to claims arising out of our operations in the normal course of business. We are currently not involved in any litigation that we believe could have a material adverse effect on our financial condition or results of operations. There is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of the executive officers of our Company or any of our subsidiaries, threatened against or affecting our Company, our common stock, any of our subsidiaries or our Company’s or our subsidiaries’ officers or directors in their capacities as such, in which an adverse decision could have a material adverse effect.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

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.

Policy on Future Related Party Transactions

Our Board has the authority, within the limitations and restrictions in our certificate of incorporation, to issue shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of any series, without further vote or action by the stockholders. The issuance of shares of preferred stock may have the effect of delaying, deferring or preventing a change in our control without further action by the stockholders. The issuance of shares of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of our common stock. In some circumstances, this issuance could have the effect of decreasing the market price of our common stock.

Undesignated preferred stock may enable our Board to render more difficult or to discourage an attempt to obtain control of the Company by means of a tender offer, proxy contest, merger or otherwise, and thereby to protect the continuity of our management. The issuance of shares of preferred stock may adversely affect the rights of our common stockholders. For example, any shares of preferred stock issued may rank senior to the common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of common stock. As a result, the issuance of shares of preferred stock, or the issuance of rights to purchase shares of preferred stock, may discourage an unsolicited acquisition proposal or bids for our common stock or may otherwise adversely affect the market price of our common stock or any existing preferred stock.

Florida Anti-Takeover Law and Certain Charter and Bylaw Provisions

Certain provisions of Florida law and our Charter and bylaws could make it more difficult to acquire us by means of a tender offer, a proxy contest or otherwise, or to remove incumbent officers and directors. These provisions, summarized below, may discourage certain types of takeover practices and takeover bids, and encourage persons seeking to acquire control of our Company to first negotiate with us. We believe that the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging such proposals because, among other things, negotiation of such proposals could result in an improvement of their terms.

Florida Law

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 FBCA, 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 FBCA 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.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of:

Duos Technologies Group, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Duos Technologies Group, Inc. and Subsidiaries (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of operations, changes in stockholders’ equity and cash flows for each of the two years in the period ended December 31, 2022 and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2022 and 2021, and the consolidated results of its operations and its cash flows for each of the two years in the period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

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

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

Critical Audit Matters

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

F-2

Percentage of Completion Revenue Recognition & Related Contract Assets and Contract Liabilities

As described in footnote 1, “Revenue Recognition – Technology Systems” and footnote 8, “Revenues and Contract Accounting” to the consolidated financial statements, the Company recognizes revenue over time using a cost-based input methodology in which significant judgement is required to estimated 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. In addition, contract assets on uncompleted contracts represent cumulative revenues in excess of billings on uncompleted contracts accounted for under the percentage of completion contract method. Contract liabilities on uncompleted contracts represent billings that exceed cumulative revenues recognized on uncompleted contracts accounted for under the percentage of completion contract method.

We identified this percentage of completion revenue recognition as a critical audit matter. Auditing management’s estimates and judgments regarding forecasts of total estimated costs to complete projects is especially challenging and complex.

The primary procedures we performed to address this critical audit matter included (a) evaluated the reasonableness of management’s cost estimates to complete projects by comparing them to historical information, year-to-date current information, information available on projects subsequent to year end, and other supporting information, (b) performed ratio analysis and gross margin comparisons when applicable on a sample of technology systems revenues (c) agreed cost details to supporting documents, (d) confirmed billings with customers and/or traced cash receipts to bank statements, (e) recomputed the revenue earned and recognized, and (f) recomputed the contract asset or liability

Analysis of Liquidity and Going Concern

As summarized in Footnote 2 “Liquidity” to the consolidated financial statements, the Company has a history of net losses and net cash used in operating activities and believes such conditions will continue for a period of time into the future. These are considered adverse conditions or events that lead management to consider whether there is substantial doubt about the ability of the Company to continue as a going concern for a reasonable period of time or whether such concerns are alleviated with management’s plans.

We identified the going concern risk analysis as a critical audit matter. Auditing management’s going concern analysis including their process to develop the analysis and the projections of future cash flows, operating trends, and assessments of internal and external matters that may affect the Company’s future operations and cash flows involved a high degree of subjectivity. Additionally, auditing management’s plans to address the going concern risk involved highly subjective auditor judgment.

The primary procedures we performed to address this critical audit matter included (a) Assessed the reasonableness of management’s process for developing their assessment of whether a going concern risk exists, (b) Assessed the reasonableness of assumptions management used in their future cash flow projections including comparison to prior year results, consideration of positive and negative evidence impacting management’s forecasts, and consideration of the Company’s financing arrangements in place as of the report date, (c) Developed our own independent calculation of expected source and use of funds, and cash flows and needs of the Company over the one year period from the date of issuance of the consolidated financial statements, (d) Confirmed cash balances as of December 31, 2022 with the banks and tested management’s bank reconciliations and inspected the bank balances in March 2023 after the $4,000,000 capital raise, (e) Identified management’s plans for dealing with the adverse conditions and events discussed above and assessed the reasonableness of the assumptions of such plans, (f) Assessed whether it is probable that management’s plans, when implemented, will mitigate the adverse effects of the conditions and events discussed above, (g) Concluded whether substantial doubt exists as to whether the Company can continue as a going concern for a period of one year after the consolidated financial statements are issued and (h) considered the effect of such conclusion on the consolidated financial statement disclosures.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2022 AND 2021

NOTE 1 – NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Duos Technologies Group, Inc. (the “Company”), through its operating subsidiaries, Duos Technologies, Inc. (“Duos”) and TrueVue360, Inc. (“TrueVue360”) (collectively the “Company”), develops and deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation operations. Additionally, these unique patented solutions can be employed into many other industries.

The Company has developed the Railcar Inspection Portal (RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the undercarriage. These images are then processed through various methods of artificial intelligence (“AI”) algorithms to identify specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal. This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future. Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which also directly benefits the Class 1 railroads through increasing their velocity.

The Company has also developed the Automated Logistics Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly dramatically improves the vehicle throughput on each lane on which the technology is deployed.

The Company has built a portfolio of IP and patented solutions that creates “actionable intelligence” using two core native platforms called Centraco® and Praesidium™. All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various image capture devices and some sensors for input into the Centraco software.

The Company also developed a proprietary Artificial Intelligence (AI) software platform, Truevue360™ with the objective of focusing the Company’s advanced intelligent technologies in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.

Through September 30, 2021, the Company also provided professional and consulting services for large data centers and had developed a system for the automation of asset information marketed as DcVue™. The Company had deployed its DcVue software at one beta site. This software was used by Duos’ consulting auditing teams. DcVue was based upon the Company’s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed software product. The Company ceased offering this product in 2021.

The Company’s strategy is to deliver operational and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics and U.S. Government Sectors, offer both one-time equipment sales and capital lease pricing models, and longer-term offer subscription pricing, to customers that increases recurring revenue, grows backlog and improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based work force where employees enjoy their work and are incentivized to excel and remain with the Company.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Duos Technologies, Inc. and TrueVue360, Inc. All inter-company transactions and balances are eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. The most significant estimates in the accompanying consolidated financial statements include the allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues and the total estimated costs to determine progress towards contract completion, valuation of inventory, estimates of the valuation of right of use assets and corresponding lease liabilities, valuation of warrants and valuation of stock-based awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

Concentrations

Cash Concentrations

Cash is maintained at financial institutions and at times, balances may exceed federally insured limits. We have not experienced any losses related to these balances. As of December 31, 2022, the Company had balances in a financial institution which combined exceeded federally insured limits by approximately $688,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s consolidated financial condition, results of operation and cash flows.

Significant Customers and Concentration of Credit Risk

The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows:

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, a single 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.

At December 31, 2022, four customers accounted for 34%, 31%, 19% and 10% of accounts receivable. At December 31, 2021, two customers accounted for 81% and 10% of accounts receivable. Much of the credit risk is mitigated since all of the customers listed here are Class 1 railroads with a history of timely payments to us.

Geographic Concentration

Approximately 41% and 86% of revenue in 2022 and 2021, respectively, is generated from customers outside of the United States.

F-11

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

Significant Vendors and Concentration

In some instances, the Company relies on a limited pool of vendors for key components related to the manufacturing of its subsystems. These vendors are primarily focused on camera, server and lighting technologies integral to the Company’s solution where possible, the Company seeks multiple vendors for key components to mitigate vendor concentration risk.

Fair Value of Financial Instruments and Fair Value Measurements

The Company follows Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for assets and liabilities measured at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements.

ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, ASC 820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

These inputs are prioritized below:

Level 1: | Observable inputs such as quoted market prices in active markets for identical assets or liabilities
Level 2: | Observable market-based inputs or unobservable inputs that are corroborated by market data
Level 3: | Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions that the market participants would use in the asset or liability based on the best available information.

The Company analyzes all financial instruments with features of both liabilities and equity under the Financial Accounting Standard Board’s (“FASB”) accounting standard for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The estimated fair value of certain financial instruments, including accounts receivable, prepaid expenses, accounts payable, accrued expenses and notes payable are carried at historical cost basis, which approximates their fair values because of the short-term nature of these instruments.

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 accounts, 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.

Inventory

Inventory consists primarily of spare parts, consumables and long-lead components to be used in the production of our technology systems or in connection with maintenance agreements with customers. Inventory is stated at the lower of cost or net realizable value. Any inventory determined to be obsolete is written off. Inventory cost is primarily determined using the weighted average cost method.

F-12

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation. Depreciation is provided by the straight-line method over the estimated economic life of the property and equipment (three 3 to five 5 years). When assets are sold or retired, their costs and accumulated depreciation are eliminated from the accounts and any gain or loss resulting from their disposal is included in the statement of operations. Leasehold improvements are expensed over the shorter of the term of our lease or their useful lives.

Software Development Costs

Software development costs incurred prior to establishing technological feasibility are charged to operations and included in research and development costs. The technological feasibility of a software product is established when the Company has completed all planning, designing, coding, and testing activities that are necessary to establish that the product meets its design specifications, including functionality, features, and technical performance requirements. Software development costs incurred after establishing technological feasibility for software sold as a perpetual license, as defined within ASC 985-20 (Software – Costs of Software to be Sold, Leased, or Marketed) are capitalized and amortized on a product-by-product basis when the product is available for general release to customers.

Patents and Trademarks

Patents and trademarks which are stated at amortized cost, relate to the development of video surveillance security system technology and are being amortized over 17 years.

Long-Lived Assets

The Company evaluates the recoverability of its property, equipment, and other long-lived assets 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 in the event the net book values of such assets exceed the estimated future undiscounted cash flows attributable 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 exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Product Warranties

The Company has a 90-day warranty period for materials and labor after final acceptance of a project. If any parts are defective they are replaced under our vendor warranty which is usually 12 to 36 months. Final acceptance terms vary by customer. Some customers have a cure period for any material deviation and if the Company fails or is unable to correct any deviations, a full refund of all payments made by the customer will be arranged by the Company. As of December 31, 2022 and 2021, the warranty costs have been de-minimis, therefore no accrual of warranty liability has been made.

Loan Costs

Loan costs paid to lenders, or third parties are recorded as debt discounts to the related loans and amortized to interest expense over the loan term.

Sales Returns

Our systems are sold as integrated systems and there are no sales returns allowed.

Revenue Recognition

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 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.

F-13

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

Revenue is recognized by evaluating our 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 revenue from four sources:

(1) Technology Systems

(2) AI Technologies

(3) Technical Support

(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 now bases its 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 indirect 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 Technologies

The Company has revenue from applications that incorporate artificial intelligence (AI) in the form of predetermined algorithms which provide important operating information to the users of our systems. The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue at a point in time upon 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 term 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 obligations 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.

Advertising

The Company expenses the cost of advertising. During the years ended December 31, 2022 and 2021, there were no advertising costs.

Stock Based Compensation

The Company accounts for employee and non-employee stock-based compensation in accordance with ASC 718-10, “Share-Based Payment,” which requires the measurement and recognition of compensation expense for all share-based payment awards made including stock options, restricted stock units, and stock purchases based on estimated fair values.

The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The Company’s determination of fair value 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 employee 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.

Income Taxes

The Company accounts for income taxes in accordance with the Financial Accounting Standards Board FASB Accounting Standards Codification (“ASC”) 740, Income Taxes, which requires the recognition of deferred income taxes for differences between the basis of assets and liabilities for financial statement and income tax purposes. The deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company evaluates all significant tax positions as required by ASC 740. As of December 31, 2022, the Company does not believe that it has taken any positions that would require the recording of any additional tax liability, nor does it believe that there are any unrealized tax benefits that would either increase or decrease within the next year.

Any penalties and interest assessed by income taxing authorities are included in operating expenses.

The federal and state income tax returns of the Company are subject to examination by the IRS and state taxing authorities, generally for three years after they were filed. Tax years 2019, 2020 and 2021 remain open for potential audit.

Earnings (Loss) Per Share

Basic earnings per share (EPS) are computed by dividing net loss applicable to common stock by the weighted average number of common shares outstanding. Diluted net loss per common share is computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding for the period and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options, stock warrants, convertible debt instruments, convertible preferred stock or other common stock equivalents. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive. At December 31, 2022, there was an aggregate of 147,591 outstanding warrants to purchase shares of common stock. At December 31, 2022, there was an aggregate of 926,266 employee stock options to purchase shares of common stock. At December 31, 2022, 433,000 common shares were issuable upon conversion of Series D Convertible Preferred Stock, all of which were excluded from the computation of dilutive earnings per share because their inclusion would have been anti-dilutive.

At December 31, 2021, there was an aggregate of 1,376,466 outstanding warrants to purchase shares of common stock. At December 31, 2021, there was an aggregate of 431,266 employee stock options to purchase shares of common stock. At December 31, 2021, 121,571 common shares were issuable upon conversion of Series B Convertible Preferred Stock, all of which were excluded from the computation of dilutive earnings per share because their inclusion would have been anti-dilutive. Also, at December 31, 2021, 454,546 common shares were issuable upon conversion of Series C Convertible Preferred Stock, all of which were excluded from the computation of dilutive earnings per share because their inclusion would have been anti-dilutive.

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02, Leases (Topic 842). The updated guidance requires lessees to recognize right-of-use (“ROU”) assets and lease liabilities for most operating leases. In addition, the updated guidance requires that lessors separate lease and non-lease components in a contract in accordance with the new revenue guidance in ASC 606. This guidance is effective for interim and annual reporting periods beginning after December 15, 2018.

The Company adopted this guidance effective January 1, 2019, using the modified retrospective method, whereby a cumulative effect adjustment was made as of the date of initial application. The Company also applied the package of practical expedients to leases that commenced before the effective date whereby the Company elected to not reassess the following: (i) whether any expired or existing contracts contain leases and (ii) initial direct costs for any existing leases. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components as a single lease component.

The adoption of ASU 2016-02 did not materially affect our consolidated statement of operations or our consolidated statement of cash flows.

For contracts entered into on or after the effective date, at the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company’s assessment is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether it has the right to direct the use of the asset.

Operating ROU assets represent the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date to determine the present value of future payments. The lease term includes all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included in general and administrative expenses in the consolidated statements of operations.

Recent Accounting Pronouncements

From time to time, the FASB or other standards setting bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards Update (“ASU”).

In August 2020, the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. During 2022, the Company did not issue any convertible instruments or contracts and does not foresee any such issuances in the near future.

In May 2021, the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2021. During 2022, the Company did not issue any equity classified written call options or warrant during the year and does not foresee any issuances in the near future.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which significantly changes how entities will measure credit losses for most financial assets, including accounts receivable. ASU No. 2016-13 will replace today’s “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. On November 15, 2019, the FASB delayed the effective date of Topic 326 for certain small public companies and other private companies until fiscal years beginning after December 15, 2022 for SEC filers that are eligible to be smaller reporting companies under the SEC’s definition, as well as private companies and not-for-profit entities. The Company is currently evaluating the new guidance and has not yet determined whether the adoption of the new standard will have a material impact on its consolidated financial statements or the method of adoption.

In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The guidance was issued as improvements to ASU No. 2016-13 described above. The vintage disclosure changes require an entity to disclose current-period gross write-offs by year of origination for financing receivables. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. The amendments should be applied prospectively. Early adoption of the amendments is permitted, including adoption in an interim period. The amendments will impact our disclosures but will not otherwise impact the consolidated financial statements. The Company is currently evaluating the new guidance.

Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.

NOTE 2 – LIQUIDITY

As reflected in the accompanying consolidated financial statements, the Company had a net loss of $6,864,783 for the year ended December 31, 2022. During the same period, cash used in operating activities was $7,873,307. The working capital surplus and accumulated deficit as of December 31, 2022, were $2,339,052 and $52,361,834, 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 offering and a private placement which were completed during the first quarter of 2022 and during third and fourth quarters of 2022 as well as the first quarter of 2023.

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 2022 in raising gross proceeds of over $10,100,000 from the sale of both common shares and Series D Preferred Stock. Additionally, late in the first quarter of 2023, the Company raised gross proceeds of $4,000,000 from the issuance of Series E Preferred Stock (See Note 16). 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, 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 affect 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. 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 date of this report.

In addition, management has been taking 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 Series E Preferred Stock offering coupled with an S-3 shelf registration availability starting in the second quarter of 2023, 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 positive signs from new commercial engagements that indicate improvements in future commercial opportunities.

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 2023 and beyond. As a result, we expect to generate sufficient revenue and to attain profitable operations with minimal cash use in the next 12 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.

Disaggregation of Revenue The Company is following the guidance of ASC 606-10-55-296 and 297 for disaggregation of revenue. Accordingly, revenue has been disaggregated according to the nature, amount, timing and uncertainty of revenue and cash flows. We are providing qualitative and quantitative disclosures.

Qualitative:

1. We have four distinct revenue sources:

a. Technology Systems (Turnkey, engineered projects);

b. AI Technology (Associated maintenance and support services);

c. Technical Support (Licensing and professional services related to auditing of data center assets); and

d. Consulting Services (Predetermined algorithms to provide important operating information to the users of our systems).

2. We currently operate in North America including the USA, Mexico and Canada.

3. Our customers include rail transportation, commercial, government, banking and IT suppliers.

4. Our technology systems and equipment projects fall into two types:

a. Transfer of goods and services are over time.

b. Goods delivered at point in time.

5. Our services & maintenance contracts are fixed price and fall into two duration types:

a. Turnkey engineered projects and professional service contracts that are less than one year in duration and are typically one to two quarters in length; and

b. Maintenance and support contracts ranging from one to five years in length.

Segment Information

The Company operates in one reportable segment.

NOTE 9 – DEFERRED COMPENSATION

As of December 31, 2022, and 2021, the Company has accrued $297,620 and $505,896, respectively, of deferred compensation relating to individual agreements with the former CEO and sales staff, which are included in the accompanying consolidated balance sheet in accrued expenses. (See Note 10)

NOTE 10 – COMMITMENTS AND CONTINGENCIES

Operating Lease Obligations

On July 26, 2021, the Company entered a new operating lease agreement for office and warehouse combination space of 40,000 square feet, with the lease commencing on November 1, 2021, and ending April 30, 2032. This new space combines the Company’s two separate work locations into one facility, which allows for greater collaboration and also accommodates a larger anticipated workforce and manufacturing facility. On November 24, 2021, the lease was amended to commence on December 1, 2021, and end on May 31, 2032. The Company recognized a ROU asset and operating lease liability in the amount of $4,980,104 at lease commencement. Rent for the first eleven months of the term was calculated based on 30,000 rentable square feet. The rent is subject to an annual escalation of 2.5%, beginning November 1, 2023. The Company made a security deposit payment in the amount of $600,000 on July 26, 2021. The right of use asset balance at December 31, 2022, net of amortization, was $4,689,931.

F-23

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

As of December 31, 2022, the office and warehouse lease is the Company’s only lease with a term greater than twelve months. The office and warehouse lease has a remaining term of approximately 9.5 years and includes an option to extend for two renewal terms of five years each. The renewal options are not reasonably certain to be exercised, and therefore, they are not included when determining the lease term used to establish the right-of use asset and lease liability. The Company also has several short-term leases, primarily related to equipment. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the consolidated balance sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components (such as common area maintenance) as a single lease component.

The following table shows supplemental information related to leases:

Executive Severance Agreement

On April 1, 2018, the Company entered into an employment agreement (the “Arcaini Employment Agreement”) with Gianni B. Arcaini, pursuant to which Mr. Arcaini served as Chief Executive Officer and Chairman of the Board of Directors of the Company. Under the Arcaini Employment Agreement, Mr. Arcaini was paid an annual salary of $249,260 and an annual car allowance of $18,000. In addition, as incentive-based compensation, Mr. Arcaini was entitled to 1% of annual gross revenues of the Company and its subsidiaries. The Arcaini Employment Agreement had an initial term through March 31, 2020, subject to renewal for successive one-year terms unless either party gave notice of that party’s election to not renew to the other at least 60 days prior to the expiration of the then-current term. The Arcaini Employment Agreement was approved by the Compensation Committee.

As previously disclosed, on July 10, 2020, the Company announced that Mr. Arcaini would retire from these positions, effective as of September 1, 2020 (the “CEO Transition”). In order to facilitate a transition of his duties, the Company and Mr. Arcaini entered into a separation agreement which became effective as of July 10, 2020 (the “Separation Agreement”). Pursuant to the Separation Agreement, Mr. Arcaini’s employment with the Company ended on September 1, 2020 and he will receive separation payments over a 36-month period equal to his base salary plus $75,000 as well as certain limited health and life insurance benefits. The Separation Agreement also contains confidentiality, non-disparagement and non-solicitation covenants and a release of claims by Mr. Arcaini who continued to serve as Chairman of the Board of Directors of the Company. The Corporate Governance and Nominating Committee did not submit Mr. Arcaini for re-election as a director and on November 19, 2020 at the Annual Shareholders meeting a new non-Executive Chairman was appointed.

F-24

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

In accordance with the Separation Agreement, the Company will pay to Mr. Arcaini the total sum of $747,788. Notwithstanding the foregoing, the status of Mr. Arcaini as a “Specified Employee” as defined in Internal Revenue Code Section 409A has the effect of delaying any payments to Mr. Arcaini under the Separation Agreement for six months after the Separation Date. On March 1, 2021, the Company paid to Mr. Arcaini a lump-sum amount equal to the first six months of payments, or $124,631, owed to Mr. Arcaini and the Company will continue to pay him in semi-monthly installments for 30 months thereafter, as contemplated in Mr. Arcaini’s Separation Agreement. The remaining balance of approximately $228,673 as of December 31, 2022 is included in accrued expenses in the accompanying consolidated balance sheet. In addition, the Company will pay one-half of Mr. Arcaini’s current life insurance premiums for 36 months of approximately $1,200 per month and provide and pay for his health insurance for 36 months following the Separation Date of approximately $450 per month. Unvested options in the amount of 50,358 became exercisable and vested in their entirety on the Separation Date valued at $95,127. The Company made payment of his attorneys’ fees for legal work associated with the negotiation and drafting of the Separation Agreement of approximately $17,000.

NOTE 11 – INCOME TAXES

The Company maintains deferred tax assets and liabilities that reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The deferred tax assets (liabilities) at December 31, 2022 and 2021 consist of net operating loss carryforwards and differences in the book basis and tax basis of intangible assets.

The items accounting for the difference between income taxes at the effective statutory rate and the provision for income taxes for the years ended December 31, 2022 and 2021 were as follows:

Schedule of difference between income taxes at effective statutory rate and provision for income taxes |  |  |  |  |  |

Change in valuation allowance |  |  | 1,487,238 |  |  |  | 1,413,637 |
Total provision for income tax |  | $ | — |  |  | $ | — |

The Company’s approximate net deferred tax assets as of December 31, 2022 and 2021 were as follows:

Schedule of net deferred tax assets |  |  |  |  |  |
|  | December 31, |
|  | 2022 |  |  | 2021 |
Deferred Tax Asset (Liability): |  |  |  |  |  |  |  |

Valuation allowance |  |  | (9,740,198 | ) |  |  | (8,252,960 | )
Net deferred tax assets |  | $ | — |  |  | $ | — |

The gross operating loss carryforward was approximately $39,727,050 and $33,522,769 at December 31, 2022 and 2021, respectively. The Company provided a valuation allowance equal to the net deferred income tax assets for the years ended December 31, 2022, and 2021 because it was not known whether future taxable income will be sufficient to utilize the loss carryforward and other deferred tax assets. The increase in the valuation allowance was $1,487,238 in 2022.

The potential tax benefit arising from the net operating loss carryforward of $4,357,876 from the period prior to January 1, 2018, will expire in 2037. The potential tax benefit arising from the net operating loss carryforward of $5,382,322 generated after January 1, 2018 can be carried forward indefinitely within the annual usage limitations.

F-25

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

Additionally, the future utilization of the net operating loss carryforward to offset future taxable income is subject to an annual limitation as a result of ownership or business changes that may occur in the future. The Company has not conducted a study to determine the limitations on the utilization of these net operating loss carryforwards. If necessary, the deferred tax assets will be reduced by any carryforward that may not be utilized or expires prior to utilization as a result of such limitations, with a corresponding reduction of the valuation allowance.

The Company does not have any uncertain tax positions or events leading to uncertainty in a tax position. The Company’s 2021, 2020 and 2019 Corporate Income Tax Returns are subject to Internal Revenue Service examination.

NOTE 12 – STOCKHOLDERS’ EQUITY

2016 Equity Plan

We maintained the 2016 Equity Incentive Plan (the “2016 Plan”) for employees, officers, directors and other entities and individuals whose efforts contribute to our success. The 2016 Plan terminated pursuant to its terms on December 31, 2020, although all outstanding awards on such date continue in full force and effect.

2021 Equity Plan

On May 12, 2021, the Board adopted, with shareholder approval as of July 15, 2021, 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.

F-26

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2022 AND 2021

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 approved by shareholders and adopted by the board of directors. 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

Subject to the limitations prescribed by our articles of incorporation, our board of directors is authorized to establish the number of shares constituting each series of preferred stock and to fix the designations, powers, preferences, and rights of the shares of each of those series and the qualifications, limitations and restrictions of each of those series, all without any further vote or action by our stockholders.

Each share of Series B Convertible Preferred Stock is convertible at any time at the holder’s option into a number of shares of common stock equal to $1,000 divided by the conversion price of $7.00 per share. Notwithstanding the foregoing, we shall not effect any conversion of Series B Convertible Preferred Stock, with certain exceptions, to the extent that, after giving effect to an attempted conversion, the holder of shares of Series B Convertible Preferred Stock (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of our common stock in excess of 4.99% (or, at the election of the purchaser, 9.99%) of the shares of our common stock then outstanding after giving effect to such exercise.

In connection with the Purchase Agreement, the Company also entered into a Registration Rights Agreement with the Purchasers. Pursuant to the Registration Rights Agreement, the Company shall file with the SEC a registration statement covering the resale by the Purchasers of the shares of common stock into which the shares of Series E Preferred Stock are convertible. Subject to certain conditions, the Company must cause the registration statement to be declared effective by 90 days after closing (or in the event of a full review by the SEC, by 120 days). The Registration Rights Agreement contains customary representations, warranties, agreements and indemnification rights and obligations of the parties.

Under the Purchase Agreement, the Company is required to hold a meeting of shareholders at the earliest practical date, but in no event later than 120 days after closing (or 150 days in the event of a review of the proxy statement by the Securities and Exchange Commission (the “SEC”)). As described below, the terms of the Series E Preferred Stock limit its convertibility until the Company receives shareholder approval (the “Stockholder Approval”). If the Company does not obtain the Stockholder Approval at the first meeting, it is required to hold shareholder meetings every four months until the Stockholder Approval is obtained.

The Company’s Board of Directors has designated 30,000 shares as the Series E Convertible Preferred Stock. Each share of the Series E Convertible Preferred Stock has a stated value of $1,000. The holder of the Series E Convertible Preferred Stock, the holder of the common stock and the holder of any other class or series of shares entitled to vote with the common stock shall vote as one class on all matters submitted to a vote of shareholders of the Company. Each share of Series E Convertible Preferred Stock is convertible, at any time and from time to time, at the option of the holder, into that number of shares of common stock (subject to the Beneficial Ownership Limitation) determined by dividing the stated value of such share ($1,000) by the conversion price, which is $3.00 (subject to standard anti-dilution other than provisions described below in the Purchase Agreement). The Company shall not effect any conversion of the Series E Convertible Preferred Stock, and the holder shall not have the right to convert any portion of the Series E Convertible 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 “Beneficial Ownership Limitation”).

The holder of the Series E 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 E Preferred Stock has 333 votes (subject to adjustment); provided that in no event may a holder of Series E Preferred Stock be entitled to vote a number of shares in excess of such holder’s Beneficial Ownership Limitation (as defined in the Certificate of Designation).

The Purchase Agreement also provides that the Company will not, with certain exceptions, sell or issue common stock or Common Stock Equivalents (as defined in the Purchase Agreement) on or prior to December 31, 2023 that entitles any person to acquire shares of common stock at an effective price per share less than the then conversion price of the Series E Preferred Stock without the consent of the Purchaser.

The Registration Rights Agreement contains provisions for liquidated damages equal to 1% multiplied by the aggregate subscription amount paid, paid each month, in the event certain deadlines are missed.

CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

MARCH 31, 2023

(Unaudited)

NOTE 1 – NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Duos Technologies Group, Inc. (the “Company”), through its operating subsidiaries, Duos Technologies, Inc. (“Duos”) and TrueVue360, Inc. (“TrueVue360”) (collectively the “Company”), develops and deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation operations. Additionally, these unique patented solutions can be employed into many other industries.

The Company has developed the Railcar Inspection Portal (RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the undercarriage. These images are then processed through various methods of artificial intelligence (“AI”) algorithms to identify specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal. This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future. Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which also directly benefits the Class 1 railroads through increasing their velocity.

The Company has also developed the Automated Logistics Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly dramatically improves the vehicle throughput on each lane on which the technology is deployed.

The Company has built a portfolio of IP and patented solutions that creates “actionable intelligence” using two core native platforms called Centraco® and Praesidium™. All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically also customized for each unique customer and application.

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS March 31, 2023 (Unaudited)

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (all of which are of a normal recurring nature) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or for any other future period. These unaudited consolidated financial statements and the unaudited condensed notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2023.

Principles of Consolidation

The unaudited consolidated financial statements include Duos Technologies Group, Inc. and its wholly owned subsidiaries, Duos Technologies, Inc and TrueVue360 Inc. All inter-company transactions and balances are eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues and the total estimated costs to determine progress towards contract completion, valuation of inventory, estimates of the valuation of right of use assets and corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Concentrations

Cash Concentrations

Cash is maintained at financial institutions and at times, balances may exceed federally insured limits. We have not experienced any losses related to these balances. As of March 31, 2023, the balance in one financial institution exceeded federally insured limits by approximately $3,907,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s consolidated financial condition, results of operation and cash flows.

Significant Customers and Concentration of Credit Risk

The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows:

For the three months ended March 31, 2023, two customers accounted for 70% and 20% of revenues. For the three months ended March 31, 2022, four customers accounted for 35%, 24%, 13% and 11% 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.

At March 31, 2023, three customers accounted for 59%, 15%, and 11% of accounts receivable. At December 31, 2022, four customers accounted for 34%, 31%, 19% and 10% of accounts receivable. Much of the credit risk is mitigated since all the customers listed here are Class 1 railroads with a history of timely payments to us.

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS March 31, 2023 (Unaudited)

Geographic Concentration

For the three months ended March 31, 2023, approximately 25% of revenue was generated from three customers outside of the United States. For the three months ended March 31, 2022, approximately 54% of revenue was generated from three customers outside of the United States. These customers are Canadian and Mexican, and two of the three are Class 1 railroads operating in the United States.

Significant Vendors and Concentration of Credit Risk

In some instances, the Company relies on a limited pool of vendors for key components related to the manufacturing of its subsystems. These vendors are primarily focused on camera, server and lighting technologies integral to the Company’s solution. Where possible, the Company seeks multiple vendors for key components to mitigate vendor concentration risk.

Fair Value of Financial Instruments and Fair Value Measurements

The Company follows Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for assets and liabilities measured at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements.

ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, ASC 820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

These inputs are prioritized below:

Level 1: | Observable inputs such as quoted market prices in active markets for identical assets or liabilities.
Level 2: | Observable market-based inputs or unobservable inputs that are corroborated by market data.
Level 3: | Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions that the market participants would use in the valuation of the asset or liability based on the best available information.

The Company analyzes all financial instruments with features of both liabilities and equity under the Financial Accounting Standard Board’s (“FASB”) accounting standard for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The estimated fair value of certain financial instruments, including accounts receivable, prepaid expense, accounts payable, accrued expenses and notes payable are carried at historical cost basis, which approximates their fair values because of the short-term nature of these instruments.

Accounts Receivable

On January 1, 2023, the Company adopted ASC 326, “Financial Instruments - Credit Losses”. In accordance with ASC 326, an allowance is maintained for estimated forward-looking losses resulting from the possible inability of customers to make required payments (current expected losses). The amount of the allowance is determined principally on the basis of past collection experience and known financial factors regarding specific customers.

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.

Inventory

Inventory consists primarily of spare parts and consumables and long lead time components to be used in the production of our technology systems or in connection with maintenance agreements with customers. Inventory is stated at the lower of cost or net realizable value. Inventory cost is primarily determined using the weighted average cost method.

Software Development Costs

Software development costs incurred prior to establishing technological feasibility are charged to operations and included in research and development costs. The technological feasibility of a software product is established when the Company has completed all planning, designing, coding, and testing activities that are necessary to establish that the product meets its design specifications, including functionality, features, and technical performance requirements. Software development costs incurred after establishing technological feasibility for software sold as a perpetual license, as defined within ASC 985-20 (Software – Costs of Software to be Sold, Leased, or Marketed), are capitalized and amortized on a product-by-product basis when the product is available for general release to customers.

Revenue Recognition

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 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 our 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 revenue from four sources:

(1) Technology Systems

(2) AI Technologies

(3) Technical Support

(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 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 indirect 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.

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS March 31, 2023 (Unaudited)

AI Technologies

The Company has revenue from applications that incorporate artificial intelligence (AI) in the form of predetermined algorithms which provide important operating information to the users of our systems. The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue at a point in time upon 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 term 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.

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS March 31, 2023 (Unaudited)

Leases

The Company follows ASC 842 “Leases”. This guidance requires lessees to recognize right-of-use (“ROU”) assets and lease liabilities for most operating leases. In addition, this guidance requires that lessors separate lease and non-lease components in a contract in accordance with the revenue guidance in ASC 606.

The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components as a single lease component.

At the inception of a contract the Company assesses whether the contract is, or contains, a lease. The Company’s assessment is based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether we have the right to direct the use of the asset.

Operating ROU assets represent the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date to determine the present value of future payments. The lease term includes all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included in general and administrative expenses in the consolidated statements of operations.

Earnings (Loss) Per Share

Basic earnings per share (EPS) are computed by dividing net loss applicable to common stock by the weighted average number of common shares outstanding. Diluted net loss per common share is computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding for the period and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise or conversion of stock options, stock warrants, convertible debt instruments, convertible preferred stock or other common stock equivalents. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive.

At March 31, 2023, there were (i) an aggregate of 80,091 outstanding warrants to purchase shares of common stock, (ii) employee stock options to purchase an aggregate of 924,658 shares of common stock, (iii) 433,000 common shares issuable upon conversion of Series D Convertible Preferred Stock and (iv) 1,333,334 common shares issuable upon conversion of Series E Convertible Preferred Stock, all of which were excluded from the computation of diluted earnings per share because their inclusion would have been anti-dilutive.

At March 31, 2022, there were (i) an aggregate of 1,376,466 outstanding warrants to purchase shares of common stock, (ii) employee stock options to purchase an aggregate of 1,096,266 shares of common stock and (iii) 121,571 common shares issuable upon conversion of Series B Convertible Preferred Stock, all of which were excluded from the computation of diluted earnings per share because their inclusion would have been anti-dilutive.

Recent Accounting Pronouncements

From time to time, the FASB or other standards setting bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards Update (“ASU”).

In August 2020, the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. The Company early adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a material effect on our audited consolidated financial statements.

F-44

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS March 31, 2023 (Unaudited)

In May 2021, the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur after the initial date of adoption. We adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a material effect on our audited consolidated financial statements.

Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.

NOTE 2 – LIQUIDITY

As reflected in the accompanying consolidated financial statements, the Company had a net loss of $2,143,683 for the three months ended March 31, 2023. During the same period, cash used in operating activities was $7,086. The working capital surplus and accumulated deficit as of March 31, 2023, were $3,860,339 and $54,505,517, 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 offering and a private placements which were completed during the first quarter of 2022 and during the third and fourth quarters of 2022 as well as the first quarter of 2023.

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 2022 in raising gross proceeds of over $10,100,000 from the sale of both common shares and Series D Preferred Stock. Additionally, late in the first quarter of 2023, the Company raised gross proceeds of $4,000,000 from the issuance of Series E Preferred Stock. 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, 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 filing, 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 affect 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 delays or inflationary increases and their effects on our customers in the coming quarters. 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 date of this report.

In addition, management has been taking 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, as described above, it will have sufficient sources of 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 positive signs from new commercial engagements that indicate improvements in future commercial opportunities.

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.

F-45

DUOS TECHNOLOGIES GROUP, INC. AND SUBSIDIARIES CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS March 31, 2023 (Unaudited)

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 2023 and beyond. As a result, we expect to generate sufficient revenue and to attain profitable operations with less net cash used in operating activities in the next 12 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.

NOTE 4 – COMMITMENTS AND CONTINGENCIES

Operating Lease Obligations

On July 26, 2021, the Company entered into a new operating lease agreement for office and warehouse combination space of 40,000 square feet, with the lease commencing on November 1, 2021 and ending April 30, 2032. This new space combines the Company’s two separate work locations into one facility, which allows for greater collaboration and also accommodates a larger anticipated workforce and manufacturing facility. On November 24, 2021, the lease was amended to commence on December 1, 2021 and end on May 31, 2032. The Company recognized a ROU asset and operating lease liability in the amount of $4,980,104 at lease commencement. Rent for the first eleven months of the term was calculated based on 30,000 rentable square feet. The rent is subject to an annual escalation of 2.5%, beginning November 1, 2023. The Company made a security deposit payment in the amount of $600,000 on July 26, 2021. The right of use asset balance at March 31, 2023, net of amortization, was $4,612,830.

As of March 31, 2023, the office and warehouse lease is the Company’s only lease with a term greater than twelve months. The office and warehouse lease have a remaining term of approximately 9.3 years and includes an option to extend for two renewal terms of five years each. The renewal options are not reasonably certain to be exercised, and therefore, they are not included when determining the lease term used to establish the right of use asset and lease liability. The Company also has several short-term leases, primarily related to equipment. The Company made an accounting policy election to not recognize short-term leases with terms of twelve months or less on the consolidated balance sheet and instead recognize the lease payments in expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components (such as common area maintenance) as a single lease component.

Employee Stock Purchase Plan

In the fourth quarter of 2022, the board of directors adopted an Employee Stock Purchase Plan (“ESPP”) which, subject to shareholder approval, was effective as of 1 January 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. The Company must receive (and expects to obtain) shareholder approval within 12 months before or after the date of the Plan is adopted by the Board. 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 quarter 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. Although not required by the plan, all payroll deductions received or held by the Company under the Plan, are segregated and deemed as “restricted cash” until the completion of the offering period and redemption of the applicable shares. The maximum aggregate number of shares of the Common Stock that may be issued under the ESPP is no more than 1,000,000 shares (the “ESPP Plan Share Reserve”).

| 2. | We currently operate in North America including the USA, Mexico and Canada.

| 3. | Our customers include rail transportation, commercial, government, banking and IT suppliers.

| 4. | Our services & maintenance contracts are fixed price and fall into two duration types:

Item 14. Indemnification of Directors and Officers

Florida law permits, under certain circumstances, the indemnification of any person with respect to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, to which such person was or is a party or is threatened to be made a party, by reason of his or her being an officer, director, employee or agent of the corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against liability incurred in connection with such proceeding, including appeals thereof; provided, however, that the officer, director, employee or agent acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any such third-party action by judgment, order, settlement, or conviction or upon a plea of nolo contendere or its equivalent does not, of itself, create a presumption that the person (i) did not act in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of the corporation or (ii) with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful. In the case of proceedings by or in the right of the corporation, Florida law permits indemnification of any person by reason of the fact that such person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against liability incurred in connection with such proceeding, including appeals thereof; provided, however, that the officer, director, employee or agent acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification is made where such person is adjudged liable, unless a court of competent jurisdiction determines that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

To the extent that such person is successful on the merits or otherwise in defending against any such proceeding, Florida law provides that he or she shall be indemnified against expenses actually and reasonably incurred by him or her in connection therewith.

Also, under Florida law, expenses incurred by an officer or director in defending a civil or criminal proceeding may be paid by the corporation in advance of the final disposition of such proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if he or she is ultimately found not to be entitled to indemnification by the corporation pursuant to the applicable section. Expenses incurred by other employees and agents may be paid in advance upon such terms or conditions that the Board of Directors deems appropriate.

Our Amended and Restated Articles of Incorporation provide that we shall indemnify our officers and directors (and other employees and agents if approved in writing by the Board of Directors) to the fullest extent authorized or permitted by law, as it existed when the Amended and Restated Article of Incorporation were adopted or as it may thereafter be amended. Such right to indemnification shall continue as to a person who has ceased to be a director or officer (and, if applicable, other employee or agent) and shall inure to the benefit of his or her heirs, executors and personal and legal representatives; provided, however, that, except for proceedings to enforce rights to indemnification, we shall not be obligated to indemnify any such person (or his or her heirs, executors or personal or legal representatives) in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by our Board of Directors.

II-1

The Amended and Restated Articles of Incorporation also provide that such right of indemnification shall be a contract right and shall include the right to be paid by us the expenses incurred in defending or otherwise participating in any proceeding in advance of its final disposition only upon our receipt of an undertaking, by or on behalf of such director or officer, to repay such amounts if it should be ultimately determined that he or she is not entitled to be indemnified by us as authorized by the Amended and Restated Articles of Incorporation.

The rights to indemnification and to the advance of expenses conferred in the Amended and Restated Articles of Incorporation are not exclusive of any other right which and person may have or hereafter acquire under the Amended and Restated Articles of Incorporation, the Bylaws, any statute, agreement, vote of shareholders or disinterested directors or otherwise.

Any repeal or modification of the applicable provisions of the Amended and Restated Articles of Incorporation shall not adversely affect any rights to indemnification and to the advancement of expenses as a director or officer existing at the time of such repeal or modification with respect to any acts or omissions occurring prior to such repeal or modification.

In addition to the authority granted to us by Florida law to indemnify our directors, certain other provisions of the Florida Business Corporation Act have the effect of further limiting the personal liability of our directors. Pursuant to Florida law, a director of a Florida corporation cannot be held personally liable for monetary damages to the corporation or any other person for any act or failure to act regarding corporate management or policy except in the case of certain qualifying breaches of the director’s duties.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to our directors and officers, or to persons controlling us, pursuant to our charter documents and Florida law, we have been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is therefore unenforceable.

Item 17. Undertakings

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 14 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes:

(1) | To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

| (i) | To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

| (ii) | To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

| (iii) | To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(l)(iii) do not apply if the registration statement is on Form S-1, Form S-3, Form SF-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or, as to a registration statement on Form S-3, Form SF-3 or Form F-3, is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) | That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) | To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) | That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

| (i) | If the registrant is relying on Rule 430B:

| A. | Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

II-6

| B. | Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

| (ii) | If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) | That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

| The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

| (i) | Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

| (ii) | Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

| (iii) | The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

| (iv) | Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) | For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(7) | For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-7

(8) | For purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-8
