Forward Looking Statements This presentation contains “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, as amended. Any statements that are not statements of historical fact may be deemed to be forward-looking statements. For example, words such as "may ," "will," "should," "estimates," "predicts," "potential," "continue," "strategy ," "believes," "anticipates," "plans," "expects," "intends," “opportunity ,” and similar expressions are intended to identify forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding 8x8’s recent product innovations, long term financial model, debt refinancing and repayments, customer adoption, and the impact of artificial intelligence (“ AI”). These statements are based on current expectations, estimates, forecasts, and projections about the industries in which 8x8 operates, and the beliefs and assumptions of management. Actual results may differ materially from those expressed or implied by these forward-looking statements due to a number of factors, including but not limited to, changes in market conditions, shifts in customer demand, increased competition, and general economic conditions.

Non-GAAP Measures and Guidance 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. This information should not be considered a substitute for any measures derived in accordance with GAAP. Non-GAAP Guidance The Company does not reconcile its forward-looking estimates of non-GAAP gross margin to the corresponding GAAP measure of GAAP gross margin, non-GAAP operating margins to the corresponding GAAP measures of GAAP operating margin or non-GAAP net income per share, basic and diluted, to the corresponding GAAP measure of GAAP net income (loss) per share due to the significant variability of, and difficulty in making accurate forecasts and projections with regards to, the various expenses it excludes. For example, future hiring and employee turnover may not be reasonably predictable, stock-based compensation expense depends on variables that are largely not within the control of nor predictable by management, such as the market price of 8x8 common stock, and may also be significantly impacted by events like acquisitions, the timing and nature of which are difficult to predict with accuracy . The actual amounts of these excluded items could have a significant impact on the Company's GAAP operating margins. Accordingly , management believes that reconciliations of this forward-looking non-GAAP financial measure to the corresponding GAAP measure are not available without unreasonable effort. All projections are on a non-GAAP basis.

Scale without complexity New locations, seasonal staff, and global teams are onboarded in days — not months — without adding complexity or risk to existing operations. One unified platform A single vendor , one contract, and one admin console replace the complexity of managing multiple carriers, systems, and billing relationships across regions.

AI compute has changed what a conversation is worth The conversation is now the best system of record THEN Conversations were treated as exhaust. We kept a three-line CRM note typed from memory and threw away the call, the meeting, and the context. Fragments scattered across phones, email, video, and apps, lost in time. NOW AI compute has removed the constraint. It is now practical to preserve, search, govern, and learn from every conversation at enterprise scale. A trusted, continuous history of every business relationship. “A call center client converted 10 million call recordings into vCons and checked them against the CRM. The conversations were the truth. The ‘system of record’ was the fiction.” — Jeff Pulver, The Pulver vCon Report, July 2026 Copyright 2026 8x8, Inc. or its affiliates. All rights reserved.
