Contract assets and contract liabilities on uncompleted contracts for revenues recognized over time are as follows:

Contract Assets

The Company expects to recognize all current contract liabilities within 12 months from the respective consolidated balance sheet date.

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 include various support and maintenance services will be recognized as revenue pro-rata over time during the five-year contract term. The current contract liabilities of zero 0 for just this contract as of December 31, 2025 relate to the portion of the contract value the Company expects to recognize pro-rata within the next twelve months. 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 data rights 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 payments 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 is 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.

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 December 31, 2025, the balance in contract liabilities pertaining to the value of the equity method interest will be recognized as revenue as follows:
