CN Digital Agreement

In May 2024, the Company recorded an initial deferred revenue as a contract liability in the amount of $11,161,428 of which $199,008 related to a pilot program was immediately recognized as revenue (See Note 7) and another $1,569,310 was recognized in 2024. During the year ended December 31, 2025, the Company recognized revenue of $1,461,567 from this deferred revenue. This contract liability resulted from a five-year contract with a customer where the Company received non-monetary consideration recorded as intangible assets (See Note 7). This transaction was accounted for under ASC 606-10-32-21 through ASC-606-10-32-24, Non-Cash Consideration. The performance obligations, which included various support and maintenance services were to be recognized as revenue pro-rata over time during the five-year contract term. The Company performed a recoverability test as of December 31, 2025 by comparing the carrying amount of the asset to the sum of its estimated undiscounted future cash flows. The Company determined that the carrying amount of the asset was not recoverable, as estimated undiscounted future cash flows were negligible. The Company measured the impairment loss based on the asset’s estimated fair value as of December 31, 2025. Given the absence of historical or expected future cash flows, the lack of an observable market for the asset, and the ongoing contractual dispute, the Company determined that the fair value of the CN Digital Image License was zero.

Accordingly, the Company recorded an impairment of $8,130,461, representing the full carrying amount of the CN Digital Image License. Because the asset was originally recognized as part of a non-cash exchange with a corresponding deferred liability offset recorded on the balance sheet, the impairment was recorded by eliminating both the intangible asset and the related deferred liability. As a result, the impairment did not impact the Company’s consolidated statements of operations for the year ended December 31, 2025.

Services and Consulting Related Parties

In December 2024, the Company entered into a series of contracts with Fortress under which the Company will deploy and operate a fleet of mobile gas turbines and balance-of-plant inventory, providing management, sales and operations functions to Sawgrass in connection with the assets. In exchange for services performed under the Asset Management Agreement (“AMA”), the Company received an advance cash payment and common units in Sawgrass (see Note 9). Sawgrass paid the Company $5.0 million in cash upon execution of the contract, which was applied ratably on a monthly basis against amounts incurred under the AMA for a period of 12 months in 2025. In the event that the AMA was terminated within the first 12 months, any balance remaining of the advanced funds would be credited in full to Duos.

As of December 31, 2024 deferred revenue under the arrangement was $5.0 million, comprised of the $5.0 million advance payment. The Company recognized $5.0 million in revenue under the AMA during the year ended December 31, 2025. No revenues were recognized during the three months ended March 31, 2026.

The Company also concluded that the arrangement with Sawgrass is within the scope of ASC 606, Revenue from contracts with customers, and the common units issued to the Company by Sawgrass Parent represented non-cash consideration. The initial carrying value as of December 31, 2024 of $7.2 million was measured equal to the fair value of the common units received for future services to be performed under the AMA. The Company recorded $7.2 million of deferred revenue for services to be performed under the AMA (see Note 9). During the year ended December 31, 2024, the Company did not recognize any revenue associated with the AMA. The Company initially recorded the equity method investment in Sawgrass of $7.2 million, equal to the fair value of the common units as of December 31, 2024.

As of March 31, 2026, the balance in contract liabilities pertaining to the value of the equity method interest will be recognized as revenue as follows:


Calendar Year	Amounts
2026 (Remaining)	$	2,712,375
Contract Liabilities	$	2,712,375

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 six distinct revenue sources:

a. Technology Systems (Turnkey, engineered projects);

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

c. Technical Support (Operational support, asset management of power generation systems);

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

e. Hosting (Deployment and operation of edge data centers, providing customers with cabinet space and related infrastructure service); and

f. Technology Solutions - delivers manufacturer-agnostic infrastructure sourcing, integration, and value-added

supply chain services supporting data center, AI, and enterprise deployments

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

3. Our customers include rail transportation, and commercial.

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

a. Transfer of goods and services over time.

b. Goods delivered at a 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.
