APPENDIX: NON-GAAP FINANCIAL MEASURES To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with accounting principles generally accepted in the United States ("GAAP"), the Company uses the following non-GAAP measures of financial performance: Non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income, non-GAAP net income, non-GAAP net income margin, and non-GAAP basic and diluted net income per common share: We exclude the effect of stock-based compensation expense, amortization of acquired intangible assets, and expenses associated with acquisitions from non-GAAP gross profit, non-GAAP gross margin and non-GAAP operating income. Non-GAAP net income and non-GAAP net income margin are further adjusted for estimated income tax on such adjustments. We calculate income taxes on the adjustments by applying an estimated annual effective tax rate to the adjustments. Non-GAAP basic and diluted net income per common share is non-GAAP net income attributable to common stockholders divided by the weighted average number of shares. For both basic and diluted non-GAAP net income per share, the weighted average shares we use in computing non-GAAP net income per share is equal to our GAAP weighted average shares. Non-GAAP gross margin represents non-GAAP gross profit as a percentage of revenue and non-GAAP net income margin represents non-GAAP net income as a percentage of revenue. Adjusted EBITDA and adjusted EBITDA margin: We define adjusted EBITDA as net income before interest, income taxes, depreciation, and amortization, and as further adjusted for acquisition and other related expenses, stock-based compensation expense, and other income, net. Adjusted EBITDA margin represents adjusted EBITDA as a percentage of revenue. Free cash flow: We calculate free cash flow as cash flow from operating activities less purchases of property and equipment and capitalized internal-use software development cost. We use these non-GAAP financial measures internally for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with our condensed consolidated financial statements prepared in accordance with GAAP. Our presentation of non-GAAP financial measures may not be comparable to similar measures used by other companies. We encourage investors to carefully consider our results under GAAP, as well as our supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand our business. Please see the tables included at the end of this release for the reconciliation of GAAP to non-GAAP results. Key Business Metrics Net revenue retention rate: We calculate net revenue retention rate by taking the trailing 12-month ("TTM") subscription-based revenue from our customers that had revenue in the prior TTM period and dividing that by the total subscription-based revenue for the prior TTM period. Our net revenue retention rate compares our subscription revenue from the same set of customers across comparable periods, and reflects customer renewals, expansion, contraction, and churn. Customers with trailing 12-month subscription revenue greater than $100,000 and $1 million: We calculate the number of customers with TTM product revenue greater than $100,000 and $1 million by counting the number of customers that contributed more than $100,000 and $1 million in subscription revenue in the TTM period. The number of customers with TTM subscription-based revenue of at least $100,000 and $1 million is a key indicator of the scale of our business. Our customer count is subject to adjustments for acquisitions, consolidations, spin-offs, and other market activity. doximity Proprietary 17
