Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP gross margin, non-GAAP sales and marketing, non-GAAP research and development, non-GAAP general and administrative, non-GAAP operating expenses, non-GAAP operating income/(loss), non-GAAP net income/(loss), non-GAAP net income/(loss) per share, adjusted EBITDA, and free cash flow.

We believe that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Everbridge’s financial condition and results of operations. We use these non-GAAP measures for financial, operational and budgetary decision-making purposes, to understand and evaluate our core operating performance and trends, and to generate future operating plans. We believe that these non-GAAP financial measures provide useful information regarding past financial performance and future prospects, and permit us to more thoroughly analyze key financial metrics used to make operational decisions. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial measures with other software companies, many of which present similar non-GAAP financial measures to investors.

We do not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company’s financial statements. In addition, they are subject to inherent limitations as they reflect the

exercise of judgment by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. We urge investors to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures, which are included in this press release, and not to rely on any single financial measure to evaluate our business.
