Non-GAAP Financial Measures

In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), this press release and the accompanying tables contain certain non-GAAP financial measures.  We calculate adjusted gross profit by adding back the following items to gross profit: depreciation, amortization, and stock-based compensation expense.  We calculate adjusted EBITDA by adding back or removing the following items to or from net income (loss): depreciation, intangibles amortization, interest expense, income tax expense (benefit), stock-based compensation expense, extinguishment of debt, non-recurring litigation settlement costs, the reversal of interest and penalties on accrued federal fees, and interest income and other, which consists primarily of non-cash adjustment on investment, interest income and foreign exchange gains and losses.  We calculate non-GAAP operating income (loss) as operating income (loss) excluding stock-based compensation expense, intangibles amortization, non-recurring litigation settlement costs, and the reversal of interest and penalties on accrued federal fees.  We calculate non-GAAP net income (loss) as net income (loss) excluding stock-based compensation expense, intangibles amortization, amortization of debt discount and issuance costs, extinguishment of debt, non-recurring litigation settlement costs, the reversal of interest and penalties on accrued federal fees, and non-cash adjustments on investment. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies.  Five9 considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the Company, exclusive of factors that do not directly affect what we consider to be our core operating performance, as well as unusual events.  The Company’s management uses these measures to (i) illustrate underlying trends in the Company’s business that could otherwise be masked by the effect of income or expenses that are excluded from non-GAAP measures, and (ii) establish budgets and operational goals for managing the Company’s business and evaluating its performance.  In addition, investors often use similar measures to evaluate the operating performance of a company.  Non-GAAP financial measures are presented only as supplemental information for purposes of understanding the Company's operating results. The non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP.  Please see the reconciliation of non-GAAP financial measures set forth herein and attached to this release.
