Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss. ASU 2023-07 also requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning one year later. The amendments must be applied retrospectively to all prior periods presented. The Company has adopted ASU 2023-07 effective December 29, 2024. As a result, the Company has enhanced its segment disclosures to include the presentation of cost of sales by segment and the disclosure of the Company’s CODM. The adoption of this ASU affects only the Company’s disclosures, with no impacts to its financial condition and results of operations. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires companies to disclose, on an annual basis, specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. In addition, ASU 2023-09 requires companies to disclose additional information about income taxes paid. ASU 2023-09 will be effective for annual periods beginning January 1, 2025 and will be applied on a prospective basis with the option to apply the standard retrospectively. The Company will adopt ASU 2023-09 for the period ending December 28, 2025. The adoption of this standard is not expected to have an impact on the Company’s consolidated financial position, results of operations or cash flows. In November 2024, the FASB issued ASU 2024-03, Income Statement (Topic 220): Reporting Comprehensive Income – Expense Disaggregation Disclosures, which requires the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. It also requires companies to include certain amounts that are already required to be disclosed under GAAP in the same disclosure. Additionally, it requires companies to disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and to disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. ASU 2024-03 (as further clarified through ASU No. 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40)) will be effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, with early adoption permitted and will be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the impact of the adoption of ASU 2024-03; however, the standard is not expected to have an impact on the Company’s consolidated financial position, results of operations or cash flows.
Net Income (Loss) per Common Share	Net Income (Loss) per Common Share The Company calculates net income (loss) per share in accordance with FASB ASC Topic 260, Earnings per Share (“Topic 260”). Under Topic 260, basic net income (loss) per common share attributable to the Kratos shareholders is calculated by dividing net income (loss) attributable to Kratos by the weighted-average number of common shares outstanding during the reporting period. Diluted net income (loss) per common share reflects the effects of potentially dilutive securities. Diluted net income per share for the three months ended March 30, 2025 includes the dilutive effect of an aggregate of 2.1 million shares of the Company’s common stock granted to employees under stock-based compensation plans. Diluted net income per share for the three months ended March 31, 2024 excludes the dilutive effects of awards granted to employees under stock-based compensation plans of 1.9 million shares because their inclusion would have been anti-dilutive.
