| Nasdaq: DUOT Rail Industry Ownership (North America) Approximately 1.63 million railcars RAILROADS ▪ Ownership of railcars continues to decline ▪ Virtuall y no tank car ownership due to complexities and regulations ▪ Focuses capital investment on infrastructure 16% (2022) 17% (2022) 10% (2022) SHIPPERS ▪ Shipper ownership share has declined slightly ▪ Alternative focus of capital on core business versus railcar investments ▪ Railcar maintenance and management not a core competency TTX ▪ Railroad - owned equipment pool focused on box, flat, intermodal, and gondola cars ▪ Overall market share has remained steady since 2008 at ~10% of the North American fleet 25% (2012) 19% (2012) 9% (2012) Source: UMLER as of January 2022 11 57% (2022) LESSORS ▪ Shift from railroad - and shipper - owned railcars to lessors ▪ Lessors dominate the tank car segment due to complex services and compliance requirements 47% (2012)

| Nasdaq: DUOT Rail Industry Technology Adoption Headwinds Challenges with Class 1s, Regulators, and Labor Unions: • Publicly praise the technology, but internally challenged to quickly adopt full - scale. • Capital investment needed is competing with other critical investments for the RRs. • Challenged to replace labor with technology due to regulations and labor unions. “We must find an alternate, more predictable pathway to market to achieve our growth targets.” Challenges with Supply Chain and Inflation: • The time from contract close to RIP installation is now ~six months or more due to long lead procurement items. • Difficult to hold profit margins with price increases on material while negotiating price increase with Class 1s. “ To make the pathway to market more predictable (in our control) we purchase more inventory ahead of time.” TAM for RIPs across all Class 1 track network is 150 x RIP (no change). Class 1 is slow to adopt & to push regulators for full - scale implementation on leading - edge inspection technology. 12

| Nasdaq: DUOT Transition to Subscription Business Model CURRENT OFFERING ▪ Currently operate 11 x RIPs; Q2 2023, 15 x RIPs ▪ All RIPs sold as a CAPEX model to Class 1s and Transit Agencies (mostly one - time revenue & small percentage recurring) ▪ 7 Class 1s (soon to be 6) + Major Transit Agencies DUOS DATA ▪ There are ~1.63M railcars on the North American Network. ▪ Duos will image ~5.4M railcars in FY2022 (some multiple times). ~432K (8%) owned by Class 1s with the balance held by owners who ultimately pay for the maintenance of the car. ▪ Class 1 car ownership continues to decline. ▪ Great interest by the railcar owners to access this type of data for cars they own & pay to maintain. CAPITAL FORECAST ▪ Order long lead items in advance while closing deals on initial two Subscription RIPs ▪ Expand railcar owners' network with new RIP locations ▪ Operate existing portals (up to 10xRIP) and expand another 5 x RIP by EOY 2023 SUBSCRIPTION OFFERING ▪ Subscription model significantly lowers the customer entry point making it much more attractive ▪ Subscription sold either as a flat fee and/or on a per car basis (variable rate) ▪ 6 Class 1 s + thousands of railcar owners Mission: We will own and operate a network of RIPs on key RR choke points and offer our data directly to the car owners as a subscription.
