Non-GAAP Financial Measures
This press release includes non-GAAP financial measures not presented in accordance with U.S. GAAP. A reconciliation of the most comparable GAAP measure to its non-GAAP measure is included above.
Adjusted EBITDA
We present Group adjusted EBITDA and Group adjusted EBITDA margin, non-GAAP performance measures, to supplement our results presented in accordance with U.S. GAAP. Group adjusted EBITDA is defined as earnings before interest, income tax, depreciation and amortization and other items that are unusual or not related to our revenue-generating operations, including stock-based compensation expense (including related employer payroll taxes), change in fair value of derivative warrant liabilities, remeasurement of contingent consideration, and gain or loss on foreign currency. Group adjusted EBITDA margin is calculated as Group adjusted EBITDA divided by Group revenue.
Group adjusted EBITDA and Group adjusted EBITDA margin are used by management to evaluate our core operating performance on a comparable basis and to make strategic decisions. We believe Group adjusted EBITDA and Group adjusted EBITDA margin are useful to investors for the same reasons as well as in evaluating our operating performance against competitors, which commonly disclose similar performance measures. However, our calculation of Group adjusted EBITDA and Group adjusted EBITDA margin may not be comparable to other similarly titled performance measures of other companies. Group adjusted EBITDA and Group adjusted EBITDA margin are not intended to be a substitute for any U.S. GAAP financial measure.
We do not provide a reconciliation of Group adjusted EBITDA to consolidated net income/(loss) on a forward-looking basis because we are unable to forecast certain items required to develop meaningful comparable GAAP financial measures without unreasonable efforts. These items are difficult to predict and estimate and are primarily dependent on future events. The impact of these items could be significant to our projections.
