Non-GAAP Financial Measures ROBLOX Q3 | 2021 This presentation contains the non-GAAP financial measures bookings, free cash flow, and Adjusted EBITDA. We use this non-GAAP financial information to evaluate our ongoing operations, for internal planning and forecasting purposes, and ongoing operating trends for purposes of analyzing the covenants specified in the indenture governing our senior notes due 2030. We believe that this non-GAAP financial information may be helpful to investors because it provides consistency and comparability with past financial performance. Bookings is defined as revenue plus the change in deferred revenue during the period and other non-cash adjustments. Bookings is equal to the amount of virtual currency purchased by users in a given period of measurement. We believe bookings provide a timelier indication of trends in our operating results that are not necessarily reflected in our revenue as a result of the fact that we recognize the majority of revenue over the estimated average lifetime of a paying user. The change in deferred revenue constitutes the vast majority of the reconciling difference from revenue to bookings. By removing these non-cash adjustments, we are able to measure and monitor our business performance based on the timing of actual transactions with our users and the cash that is generated from these transactions. Free cash flow represents the net cash provided by operating activities less purchases of property, equipment, and intangible assets. We believe that free cash flow is a useful indicator of our unit economics and liquidity that provides information to management and investors about the amount of cash generated from our core operations that, after the purchases of property, equipment, and intangible assets, can be used for strategic initiatives, including investing in our business, making strategic acquisitions, and strengthening our balance sheet. Adjusted EBITDA is a measure of operating performance used in certain covenant calculations specified in the indenture governing our senior notes due 2030 that is not calculated in accordance with GAAP and may not conform to the calculation of EBITDA in other circumstances. Adjusted EBITDA should not be considered as a substitute for net loss as determined in accordance with GAAP. We believe that, when considered together with reported amounts, Adjusted EBITDA is useful to investors and management in understanding our ongoing operations and ongoing operating trends for purposes of analyzing the covenants specified in the indenture governing our senior notes due 2030. Non-GAAP financial measures have limitations in their usefulness to investors because they have no standardized meaning prescribed by GAAP and are not prepared under any comprehensive set of accounting rules or principles. In addition, other companies, including companies in our industry, may calculate similarly titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial information as a tool for comparison. As a result, our non-GAAP financial information is presented for supplemental informational purposes only and should not be considered in isolation from, or as a substitute for financial information presented in accordance with GAAP. A reconciliation table of the most comparable GAAP financial measure to each non-GAAP financial measure used in this presentation is included at the end of this presentation. We encourage investors and others to review our business, results of operations, and financial information in their entirety, not to rely on any single financial measure, and to view these non-GAAP measures in conjunction with the most directly comparable GAAP financial measure. 3
