                                                                 4     Fiscal Year 2025 Guidance KBR issues the following outlook for fiscal year 2025: Fiscal Year 2025 Guidance Growth Revenues $8.7B - $9.1B + 12% - 18%, up 15% at the midpoint Adjusted EBITDA $950M - $990M + 9% - 14%, up 11% at the midpoint Adjusted EPS $3.71 - $3.95 + 11% - 18%, up 15% at the midpoint Operating cash flows $500M - $550M + 8% - 19%, up 14% at the midpoint The company does not provide reconciliations of Adjusted EBITDA and Adjusted EPS to the most comparable GAAP financial measures on a forward-looking basis because the company is unable to predict with reasonable certainty the ultimate outcome of legal proceedings, unusual gains and losses, and acquisition-related expenses without unreasonable effort, which could be material to the company’s results computed in accordance with GAAP. Management has provided the following assumptions related to fiscal year 2025 guidance: • Adjusted weighted average common shares outstanding: ~133 million • Depreciation & amortization: ~$165 million (includes ~$45 million purchased intangibles amortization) • Capital expenditures: ~$50 - 65 million • Effective tax rate: 25% - 27% • Adjusted EPS phasing: 47% 1H / 53% 2H Conference Call Details The company will host a conference call to discuss its fourth quarter and fiscal year 2024 results on Monday, February 24, 2025, at 3:00 p.m. Central Time.
