This presentation contains forward-looking statements about Everbridge, Inc. (“EVBG”, “Everbridge” or the “Company”) within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, based on management’s current expectation. Forward-looking statements include information related to our possible or assumed future results of operations and expenses, our outlook, our mission, business strategies and plans, business environment, market size, product capabilities and release timing and future growth. These statements are often identified by the use of words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “will,” “would” or the negative or plural of these words or similar expressions or variations. Such forward-looking statements are subject to a number of risks, uncertainties, assumptions and other factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to: our ability to attract new customers and retain and increase sales to existing customers; developments in the market for critical communications and enterprise safety applications and the associated regulatory environment; our estimates of market opportunity and forecasts of market growth may prove to be inaccurate; we have not been profitable on a consistent basis historically and may not achieve or maintain profitability in the future; the lengthy and unpredictable sales cycles for new customers; nature of our business exposes us to inherent liability risks; our ability to successfully integrate businesses and assets that we may acquire; our ability to maintain successful relationships with our partners; our ability to respond to competitive pressures; potential liability related to data privacy and security; our ability to protect our intellectual property rights; and the other risks detailed in our risk factors discussed in filings with the U.S. Securities and Exchange Commission (the “SEC”). Moreover, Everbridge operates in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for the Company’s management to predict all risks, nor can it assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this presentation may not occur and actual results could differ materially and adversely from those anticipated or implied. Neither Everbridge nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. We are providing this information as of the date of this presentation and do not undertake any obligation to update any forward-looking statements contained in this presentation as a result of new information, future events or otherwise, except as required by law. This presentation also contains estimates and other statistical data made by independent parties and by Everbridge relating to market size and growth and other data about the Company’s industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. Neither Everbridge nor any other person makes any representation as to the accuracy or completeness of such data or undertakes any obligation to update such data after the date of this presentation. In addition, projections, assumptions and estimates of the Company’s total addressable market, future performance and the future performance of the markets in which the Company operates are necessarily subject to a high degree of uncertainty and risk.
