We review a number of operational and financial metrics, including Dollar-Based Net Expansion Rate ("DBNE"), to evaluate our business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions. Our DBNE is not based on any standardized industry methodology and is not necessarily calculated in the same manner or comparable to similarly titled measures presented by other companies. Similarly, our DBNE may differ from estimates published by third parties or from similarly titled metrics of our competitors due to differences in methodology. The numbers that we use to calculate DBNE are based on internal data. While these numbers are based on what we believe to be reasonable judgments and estimates for the applicable period of measurement, there are inherent challenges in measuring usage. We regularly review and may adjust our processes for calculating our internal metrics to improve their accuracy. If investors or analysts do not perceive our metrics to be accurate representations of our business, or if we discover material inaccuracies in our metrics, our reputation, business, results of operations, and financial condition would be harmed.

Dollar-Based Net Expansion Rate. Our DBNE compares the total revenue in a quarter from all individual customer accounts, as identified by a unique account identifier, for which we have recognized at least $5 of revenue in the last month of the quarter, to revenue from those same accounts in the same quarter in the prior year. A single customer organization may constitute multiple unique customer accounts if it has multiple account identifiers. To calculate DBNE, we first identify the cohort of such customer accounts in the same quarter of the prior year. DBNE is the quotient obtained by dividing the revenue generated from that cohort in a quarter, by the revenue generated from that same cohort in the corresponding quarter in the prior year. When we calculate DBNE for periods longer than one quarter, we use the average of the applicable quarterly DBNEs for each of the quarters in such period. Revenue from acquisitions does not impact the DBNE calculation until the quarter following the one-year anniversary of the applicable acquisition, unless the acquisition closing date is the first day of a quarter. Revenue from divestitures does not impact the DBNE calculation beginning in the quarter the divestiture closed, unless the divestiture closing date is the last day of a quarter.

We believe that measuring DBNE provides an important indication of the performance of our efforts to increase revenue from existing customers. Our ability to drive growth and generate incremental revenue depends, in part, on our ability to maintain and grow our relationships with existing customers and to increase their use of the platform. An important way in which we have historically tracked performance in this area is by measuring the DBNE for such customer accounts. Our DBNE increases when these customers increase their usage of a product, extend their usage of a product to new applications or adopt a new product. Our DBNE decreases when these customers cease or reduce their usage of a product or when we lower usage prices on a product. As our customers grow their businesses and extend the use of our platform, they sometimes create multiple customer accounts with us for operational or other reasons. As such, when we identify a significant customer organization (defined as a single customer organization generating more than 1% of revenue in a quarterly reporting period) that has created a new customer account, this new account is tied to, and revenue from this new account is included with, the original customer account for the purposes of calculating this metric.

In addition to financial information presented in accordance with U.S. generally accepted accounting principles ("GAAP"), this presentation and the accompanying conference call include certain non-GAAP financial measures, including non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating margin, non-GAAP net income attributable to common stockholders, non-GAAP net income per share attributable to common stockholders, diluted (which we refer to as "non-GAAP diluted earnings per share"), non-GAAP income from operations, organic revenue and organic revenue growth, free cash flow and free cash flow margin. We use these non-GAAP financial measures to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that these non-GAAP financial measures may be helpful to investors because they provide consistency and comparability with past financial performance, facilitate period-to-period comparisons of results of operations and assist in comparisons with other companies, many of which use similar non-GAAP financial measures to supplement their GAAP results. We believe organic revenue and organic revenue growth are useful in understanding the ongoing results of our operations. We believe free cash flow and free cash flow margin provide useful supplemental information to help investors understand underlying trends in our business and our liquidity. These non-GAAP financial measures are presented for supplemental informational purposes only, should not be considered substitutes for financial information presented in accordance with GAAP, and may be different from similarly-titled non-GAAP measures used by other companies. A reconciliation of these measures to the most directly comparable GAAP measures is included in the appendix. We have not provided the forward-looking GAAP equivalents for certain forward-looking non-GAAP measures presented in this presentation or the accompanying conference call, or a GAAP reconciliation, as a result of the uncertainty regarding, and the potential variability of, reconciling items such as stock-based compensation expense. Accordingly, a reconciliation of these non-GAAP guidance metrics to their corresponding forward-looking GAAP equivalents is not available without unreasonable effort. However, it is important to note that material changes to reconciling items could have a significant effect on future GAAP results.

Non-GAAP Gross Profit and Non-GAAP Gross Margin. For the periods presented, we define non-GAAP gross profit and non-GAAP gross margin as GAAP gross profit and GAAP gross margin, respectively, adjusted to exclude stock-based compensation, amortization of acquired intangibles and payroll taxes related to stock-based compensation.

Non-GAAP Income from Operations and Non-GAAP Operating Margin. For the periods presented, we define non-GAAP income from operations and non-GAAP operating margin as GAAP income from operations and GAAP operating margin, respectively, adjusted to exclude, as applicable, stock-based compensation, amortization of acquired intangibles, loss on net assets divested, acquisition and divestiture related expenses, payroll taxes related to stock-based compensation, charitable contributions, restructuring costs, impairment of long-lived assets, gains or losses on lease termination and impairment loss on prepaid assets.

23

Non-GAAP Net Income Attributable to Common Stockholders and Non-GAAP Net Income Per Share Attributable to Common Stockholders. For the periods presented, we define non-GAAP net income attributable to common stockholders and non-GAAP net income per share attributable to common stockholders, diluted (which we refer to as "non-GAAP diluted earnings per share") as GAAP net income (loss) attributable to common stockholders and GAAP net income (loss) per share attributable to common stockholders, diluted, respectively, adjusted to exclude, as applicable, stock-based compensation, amortization of acquired intangibles, loss on net assets divested, acquisition and divestiture related expenses, losses (gains) on strategic investments, payroll taxes related to stock-based compensation, accretion of debt discount and issuance costs, provision of income tax effects related to non-GAAP adjustments, income tax benefit related to acquisitions, charitable contributions, share of losses from equity method investment, impairment of equity method investment, restructuring costs, impairment of long-lived assets, gains or losses on or impairment of strategic investments, gains or losses on lease termination and impairment loss on prepaid assets.

Organic Revenue. For the periods presented, we define organic revenue as GAAP revenue, excluding (i) revenue from each acquired business and revenue from incremental increases to application-to-person ("A2P") fees imposed by major U.S. carriers on our core messaging business, in each case until the beginning of the first full quarter following the one-year anniversary of the closing date of such acquisition or the initial date such fees were charged and (ii) revenue from each divested business beginning in the quarter of the closing date of such divestiture; provided that (a) if an acquisition closes or such fees are initially charged on the first day of a quarter, such revenue will be included in organic revenue beginning on the one-year anniversary of the closing date of such acquisition or the initial date such fees were charged and (b) if a divestiture closes on the last day of a quarter, such revenue will be included in organic revenue for that quarter. As used in this definition, A2P fees refers to fees imposed by U.S. mobile carriers for A2P messages delivered to their subscribers, and we pass these fees to our messaging customers at cost.

Organic Revenue Growth. For the periods presented, we calculate organic revenue growth by dividing (i) organic revenue for the period presented less organic revenue in the comparative period by (ii) organic revenue in the comparative period. If revenue from certain acquisitions, divestitures or A2P fees is included or excluded in organic revenue in the period presented, then revenue from the same acquisitions, divestitures and A2P fees is included or excluded in organic revenue in the comparative period for purposes of the organic revenue growth calculation. As a result, organic revenue used in this calculation for the comparative period will not always equal organic revenue reported for the comparative period.

Free Cash Flow and Free Cash Flow Margin. For the periods presented, we define free cash flow as net cash provided by operating activities, excluding capitalized software development costs and purchases of long-lived assets, and we define free cash flow margin as free cash flow divided by revenue.
