#18x8 Second Quarter Fiscal 2019 Earnings October 29, 2018#2Forward Looking Statements This presentation includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and Section 21E of the Securities Exchange Act of 1934. These statements relate to the release of new products, market demand for products, changing industry trends, business strategies, future operating performance and outlook. These forward-looking statements are predictions only, and actual events or results may differ materially from such statements depending on a variety of factors. These factors include, but are not limited to: ● ● Customer adoption and demand for our X-Series product line may be lower than we anticipate. Competitive dynamics of the UCaaS, CCaaS and other markets in which we compete may change in ways we are not anticipating. Third parties may assert ownership rights in our IP, which may limit or prevent our continued use of the core technologies behind our solutions. We may not achieve our target service revenue growth rate, or the revenue, earnings, bookings or other amounts we forecast in our guidance, for a particular quarter or for the full fiscal year of FY19. ● Our churn rate may be higher than we anticipate. The investments we make in increasing headcount, marketing X Series, and other areas of our business may not result in accelerated revenue growth. For a discussion of such risks and uncertainties, which could cause actual results to differ from those contained in the forward-looking statements, see "Risk Factors" in the Forms 10-K and 10-Q filed by 8x8, Inc. with the Securities and Exchange Commission. All forward-looking statements are qualified in their entirety by this cautionary statement, and 8x8, Inc. undertakes no obligation to update publicly any forward-looking statement for any reason, except as required by law, even as new information becomes available or other events occur in the future. Non-GAAP Measures This presentation contains certain financial information that has not been prepared in accordance with Generally Accepted Accounting Principles (GAAP). Management uses these non-GAAP financial measures internally in analyzing the Company's financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating the Company's ongoing operational performance. Reconciliations of these non-GAAP financial measures to the most directly comparable information derived in accordance with GAAP are presented in the Appendix at the end of this presentation. This information should not be considered a substitute for any measures derived in accordance with GAAP. In addition, this presentation includes financial measures that have been adjusted as follows: ● This presentation includes revenue figures adjusted to exclude revenue generated by DXI. As first reported in the third quarter of our 2018 fiscal year, we have de-emphasized the sale of DXI's Contact Now as a stand-alone product, and management therefore believes it is useful to exclude this revenue from period-to-period comparisons to better depict the relative performance of our core business. This presentation includes revenue figures adjusted for comparison on a constant currency basis, when management concluded that the elimination of the impact of currency fluctuations between the periods being compared would assist with the evaluation of the underlying business performance. 2 8x8#310 Team Messaging Cloud Contact X Phone Center Meetings [8] Sales *** Employees Service Customers One System of Intelligence 8x8 One cloud technology platform phone x meetings x collaboration x contact center 1m+ business users 15 global data centers Serving customers in 150+ countries Global 24/7/365 follow-the-sun customer support 170 patents awarded 3 8x8#4Q2 Fiscal 2019 Financial Results SERVICE REVENUE $81.3 million ** 30% INCREASE* mid-market/ enterprise service revenue 21% INCREASE* NOW 61% of total service revenue *Adjusting for constant currency and excluding DXI Non-GAAP Net Income is tax effected at (3%) tax rate.
