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

Contract liabilities on uncompleted contracts represent billings and/or cash received that exceed cumulative revenues recognized on uncompleted contracts accounted for under the cost-to-cost input method, which recognizes revenues based on the ratio of the cost incurred to total estimated costs.

Contract liabilities on services and consulting revenues represent billings and/or cash received in excess of revenue recognized on service agreements that are not accounted for under the cost-to-cost input method.

At March 31, 2025 and December 31, 2024, contract liabilities on uncompleted contracts and contract liabilities on services and consulting consisted of the following:

Current Contract liabilities at December 31, 2024 were $11,805,018; of which zero 0 for technology systems and $3,022,901 in services and consulting have been recognized as of March 31, 2025.

The Company expects to recognize all current contract liabilities within 12 months from the respective consolidated balance sheet date. 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 4) and another $1,370,303 was recognized in 2024. During the three months ended March 31, 2025, the Company recognized revenue of $548,122 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 4). 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 $2,192,484 for just this contract as of March 31, 2025 relate to the portion of the contract value the Company expects to recognize pro-rata within the next twelve months. The non-current contract liabilities of $6,851,513 as of March 31, 2025 represent the portion of the contract value that is expected to be recognized pro-rata beyond the next twelve months. If the Digital Image License Agreement is terminated prior to the completion of the five-year term, then the customer will pay for the maintenance and support services annually in cash.

In December 2024, the Company entered into a series of contracts with Fortress which are considered related party transactions 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 will invoice monthly under this cost plus fee contract. The Company received an advance cash payments and common units in Sawgrass (see Note 6). Sawgrass paid the Company $5.0 million in cash upon execution of the contract, which will be 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 March 31, 2025 the balance pertaining to this contract is $3,750,000 for services performed and relates to the portion of the contract value the Company expects to recognize pro-rata within the next nine months. The Company invoiced $3,010,325 in revenue under the AMA for the three months ended March 31, 2025 of which $1,250,000 was amortization of the deferred revenue.

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 which will be recognized over a period of two years (see Note 6). For the three months ended March 31, 2025, the Company recognized revenue in the amount of $904,125 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.
