“Our strong fourth quarter results capped off a record year for Five9. For the year, we grew revenue by 26% to a record $162.1 million. This revenue growth was driven by our faster growing Enterprise business, which delivered 43% growth in LTM Enterprise subscription revenue, and where we saw average deal size increase to approximately $560,000 in annual revenue. I’m also very pleased that we set an all-time record for Enterprise bookings in the fourth quarter and full year. In addition, we continued to enjoy leverage in our business model as we delivered strong improvements to our bottom line, including reaching the new milestone of positive net income in the fourth quarter. We believe our continued execution combined with our differentiated cloud contact center software, positions Five9 extremely well in this large contact center market that is still in the early days of a massive shift to the cloud.”

- Mike Burkland, President and CEO, Five9

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 expenses. We calculate adjusted EBITDA by adding back the following items to net loss: depreciation, amortization, interest expense, income tax expense, stock-based compensation expense, and interest and other, which consists primarily of interest income and foreign exchange gains and losses. We calculate non-GAAP operating income (loss) as operating loss excluding stock-based compensation, amortization of acquisition intangibles and an immaterial one time out of period adjustment for sales taxes. We calculate non-GAAP net loss as net loss excluding stock-based compensation, amortization of acquisition intangibles, extinguishment of debt, amortization of debt discount and issuance costs, and an immaterial one time out of period adjustment for sales taxes. 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.
