Non-IFRS Measures and Reconciliation of Non-IFRS Measures

This press release contains references to non-IFRS measures. These measures are used by management to evaluate the performance of the Company and do not have any meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other reporting issuers. Rather, these measures are provided as additional information to complement those IFRS measures by providing further understanding of our results of operations from management’s perspective should not be considered in isolation nor as a substitute for analysis of our financial information reported under IFRS. These non-IFRS measures are used to provide investors with alternative measures of our operating performance and liquidity and thus highlight trends in our business that may not otherwise be apparent when relying solely on IFRS measures. We also believe that securities analysts, investors and other interested parties frequently use non-IFRS measures to compare issuers. Management also uses non-IFRS measures to facilitate operating performance comparisons from period to period, the preparation of annual operating budgets and forecasts and to determine components of executive compensation. The non-IFRS measures referred to in this press release include “Adjusted EBITDA” and “Free Cash Flow”.

“Adjusted EBITDA” means earnings before income taxes, interest expense (net), share-based compensation, depreciation (including for right-of-use assets), amortization, restructuring and business integration costs, goodwill impairment and change in fair value of consideration payable.

The IFRS measure most directly comparable to Adjusted EBITDA presented in our financial statements is net loss.
