Contract Liabilities Contract liabilities represent amounts billed to clients in excess of revenue recognized to date. Revenue recognized for the three and six months ended March 27, 2026 that was previously included in the contract liability balance on September 26, 2025 was $169.6 million and $618.4 million, respectively. Revenue recognized for the three and six months ended March 28, 2025 that was included in the contract liability balance on September 27, 2024 was $172.2 million and $583.0 million, respectively. Remaining Performance Obligations The Company’s remaining performance obligations as of March 27, 2026 represent a measure of the total dollar value of work to be performed on contracts awarded and in progress. The Company had approximately $19.0 billion in remaining performance obligations as of March 27, 2026. The Company expects to recognize approximately 47% of its remaining performance obligations into revenue within the next twelve months and the remaining 53% thereafter. The majority of the remaining performance obligations after the first twelve months are expected to be recognized over a four-year period. Although our remaining performance obligations reflect business volumes that are considered to be firm, normal business activities including scope adjustments, deferrals or cancellations may occur that impact volume or expected timing of their recognition. Remaining performance obligations are adjusted to reflect any known project cancellations, revisions to project scope and cost, foreign currency exchange fluctuations and project deferrals, as appropriate.
