We collect and analyze operating and financial data to evaluate the health of our business, allocate our resources and assess our performance. EBITDA and Adjusted EBITDA In addition to total revenue, net loss and other results under GAAP, we utilize non-GAAP calculations of earnings before interest, taxes, depreciation and amortization (“EBITDA”) and adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”). EBITDA is defined as Net loss, excluding (i) convertible notes and derivative liability fair value adjustments, (ii) provision (benefit) for income taxes, (iii) depreciation and amortization, (iv) other income (expense). Adjusted EBITDA is defined as Net Loss, excluding (i) convertible notes and derivative liability fair value adjustments, (ii) provision (benefit) for income taxes, (iii) depreciation and amortization, (iv) other income (expense), (v) stock-based compensation, (vi) Form 10 transaction costs, (vii) acquisition and integration costs, and (viii) gain on revaluation of contingent consideration. The above items are excluded from Adjusted EBITDA because these items are non-cash in nature, or because the amount and timing of these items are unpredictable, are not driven by core results of operations and render comparisons with prior periods and competitors less meaningful. We believe EBITDA and Adjusted EBITDA provide useful information to investors and others in understanding and evaluating our results of operations, as well as providing useful measures for period-to- period comparisons of our business performance. Moreover, we have included EBITDA and Adjusted EBITDA in this Quarterly Report on Form 10-Q because they are key measurements used by our management team internally to make operating decisions, including those related to operating expenses, evaluate performance, and perform strategic planning and annual budgeting. However, these non-GAAP financial measures are presented for supplemental informational purposes only, should not be considered a substitute for or superior to financial information presented in accordance with GAAP, and may be different from similarly titled non-GAAP financial measures used by other companies. As such, you should consider these non-GAAP financial measures in addition to other financial performance measures presented in accordance with GAAP, including various cash flow metrics, net loss and our other GAAP results. The following table presents a reconciliation of Net Loss, the most directly comparable GAAP measure, to EBITDA and Adjusted EBITDA.

Adjusted loss from ordinary activities after tax Adjusted loss from ordinary activities after tax is defined as Net Loss, excluding (i) stock-based compensation, (ii) Form 10 transaction costs, (iii) acquisition and integration costs, (iv) gain on revaluation of contingent consideration, and (v) amortization attributable to intangible assets in connection with acquisitions. The above items are excluded from net loss because these items are non-cash in nature, or because the amount and timing of these items are unpredictable, are not driven by core results of operations and render comparisons with prior periods and competitors less meaningful.
