(1) In addition to thoseNon-GAAP measures included, and reconciled, in OpenText’s reports filed under the Securities Exchange Act of 1934, as amended, this disclosure contains the followingNon-GAAP financial measures: earnings (loss) before interest, taxes, depreciation and amortization (“EBITDA”); Adjusted EBITDA (“Adjusted EBITDA”), which further adjusts EBITDA to exclude share-based compensation, other income (expense), net and special charges (recoveries) related to restructurings and acquisitions; and EBITDA Margin and Adjusted EBITDA Margin which are calculated as EBITDA or Adjusted EBITDA, as applicable, divided by revenues as determined in accordance with U.S. GAAP.

This disclosure provides reconciliations of these measures to the most directly comparable measure under U.S. GAAP. OpenText believes that EBITDA, Adjusted EBITDA, EBITDA Margin and Adjusted EBITDA Margin improve comparability from period to period by excluding the distorting effect of certainnon-operational charges. The use of the term“non-operational charge” is defined for this purpose as an expense that does not impact the ongoing operating decisions taken by the Company’s management. OpenText believes that EBITDA, Adjusted EBITDA, EBITDA Margin and Adjusted EBITDA Margin are measures widely used by securities analysts, investors and others to evaluate the financial performance of companies in OpenText’s industry. Other companies may calculate EBITDA, Adjusted EBITDA, EBITDA Margin and Adjusted EBITDA Margin differently, and, therefore, OpenText’s measures may not be comparable to similarly titled measures of other companies. EBITDA, Adjusted EBITDA, EBITDA Margin and Adjusted EBITDA Margin are not measures of financial performance or liquidity under U.S. GAAP and should not be considered in isolation or as an alternative to net income, cash flows from operating activities and other measures determined in accordance with U.S. GAAP. Items excluded from EBITDA and Adjusted EBITDA, as noted in the above and in the following table, are significant and necessary components of the operations of OpenText’s business. Given the foregoing limitations, EBITDA, Adjusted EBITDA, EBITDA Margin and Adjusted EBITDA Margin should only be used as supplemental measures of OpenText’s operating performance.

The following chart provides unaudited reconciliations of EBITDA and Adjusted EBITDA to net income attributable to OpenText for the following periods presented:
