Non-GAAP Measurements MONDEE In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), this press release and the accompanying tables include adjusted EBITDA non-GAAP net income, and non-GAAP EPS. These non-GAAP financial measures are not calculated in accordance with GAAP as they have been adjusted to exclude the effects of stock-based compensation expenses, provision for income taxes, and the impacts of depreciation and amortization. We define Adjusted EBITDA as net loss before depreciation and amortization, provision for income taxes, interest expense (net), other income net, stock-based compensation, and gain on forgiveness of PPP loans. Non-GAAP net income (loss) is defined as net loss before the impacts of amortization of intangibles, provision for income taxes, stock-based compensation, and one time items. Non-GAAP net income (loss) per share is defined as non-GAAP net income (loss) on a per share basis. See "Reconciliation of GAAP to Non-GAAP Financial Measures" for a discussion of the applicable weighted-average shares outstanding. We believe these non-GAAP financial measures provide investors and other users of our financial information consistency and comparability with our past financial performance and facilitate period-to-period comparisons of our results of operations. With respect to adjusted EBITDA and non-GAAP net loss/ income, we believe these non-GAAP financial measures are useful in evaluating our profitability relative to the amount of revenue generated, excluding the impact of stock-based compensation expense and other one-time expenses. We also believe non-GAAP financial measures are useful in evaluating our operating performance compared to that of other companies in our industry, as these metrics eliminate the effects of stock-based compensation, which may vary for reasons unrelated to overall operating performance. We use these non-GAAP financial measures in conjunction with traditional GAAP measures as part of our overall assessment of our performance, including the preparation of our annual operating budget and quarterly forecasts, and to evaluate the effectiveness of our business strategies. Our definition may differ from the definitions used by other companies and therefore comparability may be limited. In addition, other companies may not publish this or similar metrics. Thus, our non-GAAP financial measures should be considered in addition to, not as a substitute for, nor superior to or in isolation from, measures prepared in accordance with GAAP. These non-GAAP financial measures may be limited in their usefulness because they do not present the full economic effect of our use of stock-based compensation. We compensate for these limitations by providing investors and other users of our financial information a reconciliation of the non-GAAP financial measure to the most closely related GAAP financial measures. However, we have not reconciled the non-GAAP guidance measures disclosed under "Financial Outlook" to their corresponding GAAP measures because certain reconciling items such as stock-based compensation and the corresponding provision for income taxes depend on factors such as the stock price at the time of award of future grants and thus cannot be reasonably predicted. Accordingly, reconciliations to the non-GAAP guidance measures is not available without unreasonable effort. We encourage investors and others to review our financial information in its entirety, not to rely on any single financial measure and to view non-GAAP net loss/ income and non-GAAP net loss/ income per share in conjunction with net loss and net loss per share. © 2022 All Rights Reserved | 13
