APPENDIX A

Reconciliation of Non-GAAP Financial Measures

GEO reports its financial results in accordance with accounting principles generally accepted in the United States (“GAAP”). However, management believes that certain non-GAAP financial measures provide investors with additional meaningful financial information that should be considered when assessing our underlying business performance and trends. Management also uses these non-GAAP financial measures in making financial, operating, compensation and planning decisions and in evaluating the Company’s performance. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP.
