Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements were prepared using generally accepted accounting principles for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, these financial statements do not include all information or notes required by generally accepted accounting principles for annual financial statements and should be read together with our 2024 Annual Report on Form 10-K. The condensed consolidated financial statements include all normal and recurring adjustments necessary to present fairly our financial position as of October 3, 2025, the results of our operations for the three and nine months ended October 3, 2025 and September 27, 2024, respectively, and our cash flows for the nine months ended October 3, 2025 and September 27, 2024, respectively. Our significant accounting policies are detailed in "Note 1. Significant Accounting Policies" of our 2024 Annual Report on Form 10-K. Certain amounts in prior periods have been reclassified to conform with current period presentation. The Company's fiscal year ends on the Friday closest to December 31. The three months ended October 3, 2025 and September 27, 2024 contained 91 days, and the nine months ended October 3, 2025 and September 27, 2024 contained 273 days. As discussed further in Note 17 “Discontinued Operations”, HomeSafe Alliance ("HomeSafe") informed us on June 18, 2025, that U.S. Transportation Command unexpectedly terminated HomeSafe’s role in the Global Household Goods Contract. We disposed of HomeSafe in the second quarter of fiscal 2025 and determined that this disposal met the requirements to be reported as discontinued operations. As such, the results of HomeSafe are presented as discontinued operations in the accompanying Condensed Consolidated Statements of Operations, Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Cash Flows and notes for all periods presented. We have evaluated all events and transactions occurring after the balance sheet date but before the condensed consolidated financial statements were issued and have included the appropriate disclosures. Principles of Consolidation The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of KBR, Inc. and the subsidiaries it controls, including VIEs where it is the primary beneficiary (collectively, the "Company," "KBR", "we", "us" or "our"). We account for investments over which we have significant influence, but not a controlling financial interest, using the equity method of accounting. See Note 6 "Equity Method Investments and Variable Interest Entities" to our condensed consolidated financial statements for further discussion of our equity investments and VIEs. All material intercompany balances and transactions are eliminated in consolidation. Recent Accounting Pronouncements New accounting pronouncements requiring implementation in future periods are discussed below. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, the ASU requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued. We expect this ASU to only affect our disclosures with no impacts to our results of operations, cash flows and financial condition. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 requires disclosure of additional information about certain income statement expense categories. ASU 2024-03 will be effective for our 2027 fiscal year ending December 31, 2027. Early adoption is permitted and the amendments can be applied on a prospective or retrospective basis. We expect this ASU to only affect our disclosures with no impacts to our results of operations, cash flows and financial condition.
