2025 RingCentral 2Q 2025 Financial Results

• 1. ©2025 RingCentral 2Q 2025 Financial Results

• 2. ©2025 RingCentral This presentation includes forward-looking statements within the meaning of the federal securities laws. These statements relate to, among other things, our business strategy and goals, growth of the market for our services, our future financial and operating results, including our GAAP and non-GAAP guidance, the assumptions underlying our guidance, plans to reduce expenses and share-based compensation, leverage targets, and expected contributions and benefits from new products. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. Our operations involve risks and uncertainties, many of which are outside our control, and any one of which, or a combination of which, could materially affect our results of operations and whether the forward-looking statements ultimately prove to be correct. Actual results and trends in the future may differ materially from those suggested or implied by the forward-looking statements depending on a variety of factors including those that are described in greater detail in our most recent Form 10-K filed with the Securities and Exchange Commission, and in our other filings with the Securities and Exchange Commission from time to time. All future written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the previous statements. We undertake no obligation to update any forward-looking statements that may be made to reflect events or circumstances that occur, or that we become aware of, after the date of this presentation. In this presentation, we provide certain historical non-GAAP financial measures, which are reconciled to their directly comparable GAAP financial measures. These reconciliations are presented in the Appendix at the end of this presentation. We also provide other measures such as software subscriptions, annualized exit monthly recurring subscriptions (ARR), mid-market and enterprise ARR, and enterprise ARR. Safe Harbor and Non-GAAP Measures We provide guidance on forecasted non-GAAP operating margin, non-GAAP tax rates, non-GAAP EPS, and free cash flow and free cash flow margin. Reconciliations of our forecasted non-GAAP operating margin and free cash flow to the most directly comparable GAAP financial measure is presented in the Reconciliation slides at the end of this presentation. We have not reconciled our forecasted non-GAAP EPS to its respective forecasted GAAP measure because we do not provide guidance on it. We do not provide guidance on forecasted GAAP EPS because of the inherent uncertainty and complexity involved in forecasting the intercompany remeasurement gain (loss), gain (loss) associated with investments, gain (loss) on early debt conversions, and provision (benefit) from income taxes, which could be significant reconciling items between the non-GAAP and respective GAAP measures. The intercompany remeasurement gain (loss) is affected by the movement in various exchange rates relative to the U.S. Dollar, which is difficult to predict and subject to constant change. We do not provide guidance on gain (loss) associated with investments as it is based on future share prices, which are difficult to predict and subject to inherent uncertainties. We do not provide guidance on gain (loss) on debt early conversions as it is based on future conversion requests, future share prices, and interest rates, which are difficult to predict and are subject to inherent uncertainties. We do not provide guidance on forecasted GAAP tax rates as we do not forecast discrete tax items as they are difficult to predict. The provision (benefit) from income taxes, excluding discrete items, is expected to have an immaterial impact to our GAAP EPS. We utilized a projected long-term tax rate in our computation of the non-GAAP income tax provision. For fiscal 2025, we have determined the projected non-GAAP tax rate to be 22.5%. Accordingly, a reconciliation of the non-GAAP financial measure guidance to the corresponding GAAP measure is not available without unreasonable effort.

We define our annualized exit monthly recurring subscriptions as our monthly recurring subscriptions multiplied by 12. Our monthly recurring subscriptions equal the monthly value of all customer recurring charges contracted at the end of a given month. We believe this metric is a leading indicator of our anticipated subscriptions revenue. We calculate mid-market and enterprise annualized exit monthly recurring subscriptions in the same manner as we calculate our annualized exit monthly recurring subscriptions, except that only customer subscriptions from customers generating $25,000 or more in annual recurring revenue are included. We calculate enterprise annualized exit monthly recurring subscriptions in the same manner as we calculate our annualized exit monthly recurring subscriptions, except that only customer subscriptions from customers generating $100,000 or more in annual recurring revenue are included. We define our net monthly subscription dollar retention rate as (i) one plus (ii) the quotient of dollar net change divided by average monthly recurring subscriptions. We calculate 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.
