KBR — Feb 26, 2026 release

Management has provided the following assumptions related to fiscal 2026 guidance: • Capital expenditures: ~$40 - 50 million • Effective tax rate: 26% - 28% • Depreciation & amortization: ~$165 million (includes ~$45 million purchased intangibles amortization) • Adjusted weighted average common shares outstanding: ~127 million • Phasing: 46% 1H / 54% 2H Strategic Intent to Spin Off Mission Technology Solutions On September 24, 2025, KBR announced its intention to spin off its Mission Technology Solutions segment into a separate, U.S. publicly traded company. Upon completion, KBR and its shareholders are expected to benefit from ownership in two pure‑play public companies with enhanced strategic focus, operational independence, and financial flexibility. In connection with the planned separation, certain perimeter changes were implemented in fiscal 2026 to better align the businesses ahead of the spin‑off, including the transition of Frazer‑Nash Consultancy and the UK Civil Nuclear portfolio to Sustainable Technology Solutions. These changes will be reflected in KBR’s fiscal 2026 SEC filings. Investors are encouraged to refer to the supplemental financial information available in the Investor Relations section of KBR’s website, which has been recast to reflect these updates. The planned spin‑off is intended to be tax‑free to KBR and its shareholders for U.S. federal income tax purposes and is targeting completion during the second half of 2026, subject to final approval by KBR’s Board of Directors and oth
