The results of operations and cash flows for the interim periods presented are not necessarily indicative of the results to be expected for any future interim period or for the full 2025 fiscal year.
Performance Obligations	Performance Obligations To determine the proper revenue recognition method, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. The majority of the Company's contracts have a single performance obligation as the promise to transfer the individual goods or services that is not separately identifiable from other promises in the contracts and therefore, is not distinct. The Company’s performance obligations are satisfied as work progresses or at a point in time. Revenue on the Company's cost-reimbursable contracts is recognized over time using direct costs incurred or direct costs incurred to date as compared to the estimated total direct costs for performance obligations because it depicts the transfer of control to the customer. Contract costs include labor, sub-consultant services, and other direct costs. Gross revenue from services transferred to customers at a point in time is recognized when the customer obtains control of the asset, which is generally upon delivery and acceptance by the customer of the reports and/or analysis performed. As of June 28, 2025, the Company had $980,292 of remaining performance obligations, of which $784,814 is expected to be recognized over the next 12 months. Contracts for which work authorizations have been received are included in performance obligations. Performance obligations include only those amounts that have been funded and authorized and does not reflect the full amounts the Company may receive over the term of such contracts. In the case of non-government contracts and project awards, performance obligations include future revenue at contract or customary rates, excluding contract renewals or extensions that are at the discretion of the client. For contracts with a not-to-exceed maximum amount, the Company includes revenue from such contracts in performance obligations to the extent of the remaining estimated amount. Contract Balances The timing of revenue recognition, billings, and cash collections results in billed receivables, unbilled receivables (contract assets), and billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities) on the Consolidated Balance Sheet. The liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized on these contracts as of the reporting date. This liability is generally classified as current.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is the excess of consideration paid for an acquired entity over the amounts assigned to assets acquired, including other identifiable intangible assets and liabilities assumed in a business combination. To determine the amount of goodwill resulting from a business combination, the Company performs an assessment to determine the acquisition date fair value of the acquired company’s tangible and identifiable intangible assets and liabilities. Goodwill is required to be evaluated for impairment on an annual basis or whenever events or changes in circumstances indicate the asset may be impaired. An entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. These qualitative factors include macroeconomic and industry conditions, cost factors, overall financial performance, and other relevant entity-specific events. If the entity determines that this threshold is met, then the Company applies a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The Company determines fair value through multiple valuation techniques, and weights the results accordingly. Subjective and complex judgments are required in assessing whether an event of impairment of goodwill has occurred, including assumptions and estimates used to determine the fair value of its reporting units. The Company has elected to perform its annual goodwill impairment review as of August 1 of each year. The Company conducts its annual impairment tests on the goodwill using the quantitative method of evaluating goodwill. As of August 1, 2024, the Company conducted its annual impairment tests using the quantitative method of evaluating goodwill. Based on the quantitative analyses the Company determined the fair value of each of the reporting units exceeded its carrying value. Therefore, the goodwill was not impaired and the Company did not recognize an impairment charge relating to goodwill as of August 1, 2024. Furthermore, there were no indicators, events, or changes in circumstances that would indicate goodwill was impaired during the period from August 2, 2024 through June 28, 2025. Identifiable intangible assets primarily include customer backlog, customer relationships, trade names, non-compete agreements, and developed technology. Amortizable intangible assets are amortized on either a straight-line or sum-of-the-years' digits basis over their estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the assets may be impaired. If an indicator of impairment exists, the Company compares the estimated future cash flows of the asset, on an undiscounted basis, to the carrying value of the asset. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then impairment, if any, is measured as the difference between fair value and carrying value, with fair value typically based on a discounted cash flow model. There were no indicators, events, or changes in circumstances that would indicate intangible assets were impaired during the six months ended June 28, 2025.
