Note Regarding Non-GAAP Financial Data Information Booz Allen discloses in the following information Adjusted Operating Income, Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow which are not recognized measurements under GAAP, and when analyzing Booz Allen’s performance or liquidity as applicable, investors should (i) evaluate each adjustment in our reconciliation of Operating and Net Income to Adjusted Operating Income, Adjusted EBITDA and Adjusted Net Income, and cash flow to free cash flow, and the explanatory footnotes regarding those adjustments, and (ii) use Adjusted EBITDA, Adjusted Net Income, Adjusted Operating Income, and Adjusted Diluted EPS in addition to, and not as an alternative to operating income, net income or Diluted EPS as a measure of operating results with cash flow in addition to and not as an alternative to net cash generated from operating activities as a measure of liquidity, each as defined under GAAP. The Financial Appendix includes a reconciliation of Adjusted Operating Income, Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted EPS, and Free Cash Flow to the most directly comparable financial measure calculated and presented in accordance with GAAP.
