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.

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.

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.

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.

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.

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.

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.

Sales Returns

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

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.

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.

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.

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.
