Disaggregation of Revenue

See “Note 18 – Segments Information” for the Company’s revenues by each of our segments.

Contract Assets and Contract Liabilities

During the three months ended September 30, 2026 and September 30, 2025, the Company recognized revenue of $14.1 million and $12.9 million, respectively and $185.0 million and $178.1 million during the nine months ended September 30, 2026 and September 30, 2025, respectively, that was included in the corresponding contract liability balances at December 31, 2025 and December 31, 2024, respectively.

During the three months ended September 30, 2026, there was no significant write-down of contract assets. For the nine months ended September 30, 2026, the Company recognized a reduction to contract assets of $14.8 million and

an increase to contract liabilities of $61.2 million due to two loss position contracts and related cumulative catch-up reductions to revenue. These contracts and related contract assets and liabilities are classified as held for sale as of September 30, 2026. Refer to the Contracts Held for Sale section below. There was no significant write-down of contract assets recognized during the three and nine months ended September 30, 2025.

Contracts Held for Sale

During the second quarter of 2026 management committed to a plan to sell two Remote Programs within the Federal Solutions segment as part of its strategy to transfer the remaining contractual obligations to a third party. Management expects the sale and novation to be completed by the end of 2026. The assets and liabilities are classified as held for sale, reported at the lower of the carrying value or fair value less cost to sell and consist primarily of property and equipment, net of $2.4 million, contract assets of $18.6 million and contract liabilities of $57.4 million as of September 30, 2026. These balances are reported as assets held for sale and liabilities held for sale on the consolidated balance sheet.

Accounts Receivable, net

Billed accounts receivable represents amounts billed to clients that have not been collected. Unbilled accounts receivable represents amounts where the Company has a present contractual right to bill but an invoice has not been issued to the customer at the period-end date. Receivables from contracts with the U.S. federal government and its agencies were 15% and 19% as of September 30, 2026 and December 31, 2025, respectively.

The allowance for doubtful accounts was determined based on consideration of trends in actual and forecasted credit quality of clients, including delinquency and payment history, type of client, such as a government agency or commercial sector client, and general economic conditions and particular industry conditions that may affect a client’s ability to pay.

Transaction Price Allocated to the Remaining Unsatisfied Performance Obligations

The Company’s remaining unsatisfied performance obligations (“RUPO”) as of September 30, 2026 represent a measure of the total dollar value of work to be performed on contracts awarded and in-progress. The Company had $7.6 billion in RUPO as of September 30, 2026.

RUPO will increase with awards of new contracts and decrease as the Company performs work and recognizes revenue on existing contracts. Projects are included within RUPO at such time the project is awarded and agreement on contract terms has been reached.

RUPO is comprised of: (a) original transaction price, (b) change orders for which written confirmations from our customers have been received, (c) pending change orders for which the Company expects to receive confirmations in the ordinary course of business, and (d) claim amounts that the Company has made against customers for which it has determined that it has a legal basis under existing contractual arrangements and a significant reversal of revenue is not probable, less revenue recognized to-date.
