Adjusted EBITDA Reconciliation 15 The following table presents the reconciliation of net income attributable to GRSA standalone to EBITDA and Adjusted EBITDA for the periods below: NOTE ON RECONCILIATION OF NON-GAAP FINANCIAL MEASURES: A non-GAAP financial measure is a numerical measure of historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with GAAP in the balance sheets, statements of operations, or statements of cash flows; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measures so calculated and presented. EBITDA and Adjusted EBITDA are not financial measures recognized under GAAP. EBITDA and Adjusted EBITDA are presented and discussed because management believes they enhance the understanding of the financial performance of Signature's and GRSA's operations by investors and lenders. As a complement to financial measures recognized under GAAP, management believes that EBITDA and Adjusted EBITDA assist investors who follow the practice of some investment analysts who adjust GAAP financial measures to exclude items that may obscure underlying performance and distort comparability. Because EBITDA and Adjusted EBITDA are not measures recognized under GAAP, they are not intended to be presented herein as a substitute for net earnings as an indicator of operating performance. EBITDA and Adjusted EBITDA are primarily performance measurements the Company's senior management and Board expect to use to evaluate certain operating results. Signature calculates EBITDA and Adjusted EBITDA as earnings before interest, taxes, depreciation and amortization, or EBITDA, which is then adjusted to remove or add back certain items, or Adjusted EBITDA. These items are identified below in the reconciliation of GRSA's net earnings to EBITDA and Adjusted EBITDA. Net earnings is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. Signature’s calculation of EBITDA and Adjusted EBITDA may be different from the calculation used by other companies for non-GAAP financial measures having the same or similar names; therefore, they may not be comparable to other companies.
