Safe Harbor Non-GAAP Financial Measures and Key Operating Metrics To supplement its consolidated financial statements, which are prepared and presented in accordance with U.S. GAAP, Wix uses the following non-GAAP financial measures: bookings, cumulative cohort bookings, revenue on a constant currency basis, non-GAAP gross margin, non-GAAP operating income (loss), free cash flow, free cash flow margins, non-GAAP operating expenses, non-GAAP cost of revenue expense (collectively the "Non-GAAP financial measures"). Bookings is a non-GAAP financial measure calculated by adding the change in deferred revenues and the change in unbilled contractual obligations for a particular period to revenues for the same period. Bookings include cash receipts for premium subscriptions purchased by users as well as cash we collect from business solutions, as well as payments due to us under the terms of contractual agreements for which we may have not yet received payment. Cash receipts for premium subscriptions are deferred and recognized as revenues over the terms of the subscriptions. Cash receipts for payments and the majority of the additional products and services (other than Google Workspace) are recognised as revenues upon receipt. Committed payments are recognised as revenue as we fulfill our obligation under the terms of the contractual agreement. Non-GAAP gross margin represents gross profit calculated in accordance with GAAP as adjusted for the impact of share-based compensation expense, acquisition-related expenses and amortization, divided by revenue. Non-GAAP operating income (loss) represents operating income (loss) calculated in accordance with GAAP as adjusted for the impact of share-based compensation expense, amortization, acquisition-related expenses and sales tax expense accrual and other G&A expenses (income). Free cash flow represents net cash provided by (used in) operating activities less capital expenditures. Free cash flow margins represent free cash flow divided by revenue. Non-GAAP cost of revenue represents cost of revenue calculated in accordance with GAAP as adjusted for the impact of share-based compensation expense, acquisition-related expenses and amortization. Non-GAAP operating expenses represent operating expenses calculated in accordance with GAAP as adjusted for the impact of share-based compensation expense, acquisition-related expenses and amortization. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. The Company uses these non-GAAP financial measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. The Company believes that these measures provide useful information about operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making. For more information on the non-GAAP financial measures, please see the reconciliation tables provided below. The accompanying tables have more details on the GAAP financial measures that are most directly comparable to non-GAAP financial measures and the related reconciliations between these financial measures. The Company is unable to provide reconciliations of free cash flow, free cash flow margins, cumulative cohort bookings, non-GAAP gross margin, and non-GAAP operating expenses to their most directly comparable GAAP financial measures on a forward-looking basis without unreasonable effort because items that impact those GAAP financial measures are out of the Company's control and/or cannot be reasonably predicted. Such information may have a significant, and potentially unpredictable, impact on our future financial results. Analyst & Investor Day | May 2022 2 Wix
