Forward-Looking Statements

This press release contains “forward-looking statements”, including statements regarding our strategy to acquire enterprise customers and our anticipated future financial results. Forward-looking statements are subject to known and unknown risks and uncertainties and are based on assumptions that may prove to be incorrect, which could cause actual results to differ materially from those expected or implied by the forward-looking statements. Among the important factors that could cause actual results to differ materially from those in any forward-looking statements are: our ability to grow at our expected rate of growth; our ability to add and retain larger customers and enter new geographies and markets; our ability to continue to release, and gain customer acceptance of, new and improved versions of our services; our ability to compete successfully against existing and new competitors; our ability to enter into and maintain relationships with carriers and other resellers; our ability to manage our expenses and growth; and general market, political, economic, and business conditions; as well as those risks and uncertainties included under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission; and in other filings we make with the Securities and Exchange Commission from time to time.

All forward-looking statements in this press release are based on information available to RingCentral as of the date hereof, and we undertake no obligation to update these forward-looking statements, to review or confirm analysts’ expectations, or to provide interim reports or updates on the progress of the current financial quarter.

Non-GAAP Financial Measures

Our reported results include certain Non-GAAP financial measures, including Non-GAAP operating income (loss) and Non-GAAP net income (loss) per share. We define Non-GAAP operating income (loss) as operating income (loss) excluding share-based compensation, legal settlements and other one-time items. We define Non-GAAP net income (loss) per share as net income (loss) per share assuming all preferred stock converted into common stock at the later of the start of the period or the date of issuance.

We have included Non-GAAP operating income (loss) and Non-GAAP net income (loss) per share in this press release because they are key measures used by us to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget, and to develop short and long-term operational plans. In particular, the exclusion of certain expenses in calculating Non-GAAP operating income (loss) and Non-GAAP net income (loss) per share can provide a useful measure for period-to-period comparisons of our core business.

Although Non-GAAP operating income (loss) and Non-GAAP net income (loss) per share are frequently used by investors in their evaluations of companies, these non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Because of these limitations, these non-GAAP financial measures should be considered alongside other financial performance measures.

We have not reconciled Non-GAAP operating income (loss) to operating income (loss) guidance or Non-GAAP net income (loss) per share to net income (loss) per share guidance because we do not provide guidance for share-based compensation expense, provision for income taxes, interest income, interest expense, and other income and expenses, which are reconciling items between Non-GAAP operating income (loss) to operating income (loss) guidance or Non-GAAP net income (loss) per share to net income (loss) per share. As items that impact net income (loss) are out of our control and/or cannot be reasonably predicted, we are unable to provide such guidance. Accordingly, reconciliation to net income (loss) is not available without unreasonable effort. For a reconciliation of historical non-GAAP financial measures to the nearest comparable GAAP measures, see the reconciliation tables included in this press release.

Our reported results also include our total annualized exit monthly recurring subscriptions, RingCentral Office annualized exit monthly recurring subscriptions, and net monthly subscription dollar retention. We define our total annualized exit monthly recurring subscriptions as our total monthly recurring subscriptions multiplied by 12. Our total monthly recurring subscriptions equals the monthly value of all customer subscriptions in effect at the end of a given month. We believe this metric is a leading indicator of our anticipated subscriptions revenue. We calculate our RingCentral Office annualized exit monthly recurring subscriptions in the same manner as we calculate our total annualized exit monthly recurring subscriptions, except that only customer subscriptions from RingCentral Office customers are included when determining monthly recurring subscriptions for the purposes of calculating this key business metric. We define Dollar Net Change as the quotient of (i) the difference of our Monthly Recurring Subscriptions at the end of a period minus our Monthly Recurring Subscriptions at the beginning of a period minus our Monthly Recurring Subscriptions at the end of the period from new customers we added during the period, (ii) all divided by the number of months in the period. We define our Average Monthly Recurring Subscriptions as the average of the Monthly Recurring Subscriptions at the beginning and end of the measurement period.
