Business Outlook

Given the announcement made on July 18, 2021 regarding Five9's entry into a definitive agreement to be acquired by Zoom Video Communications, Inc., the Company will not be providing financial guidance for the third quarter or full year 2021. The Company's previously issued full year financial guidance should no longer be relied upon.

Conference Call Details

Due to the pending transaction, the Company will not host a conference callin conjunction with this release. Please visit the Investor Relations section of the Company's website at http://investors.five9.com/ for the latest Five9 releases and information.

Non-GAAP Financial Measures

In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), this press release and the accompanying tables contain certain non-GAAP financial measures. We calculate adjusted gross profit and adjusted gross margin by adding back the following items to gross profit: depreciation, intangibles amortization, stock-based compensation, COVID-19 relief bonus for employees and one-time integration costs. We calculate adjusted EBITDA by adding back or removing the following items to or from GAAP net income (loss): depreciation and amortization, stock-based compensation, interest expense, loss on early extinguishment of debt, other expense and interest (income), acquisition-related transaction costs and one-time integration costs, COVID-19 relief bonus for employees, contingent consideration expense and provision for (benefit from) income taxes. We calculate non-GAAP operating income by adding back or removing the following items to or from GAAP operating income (loss): stock-based compensation, intangibles amortization, acquisition-related transaction costs and one-time integration costs and contingent consideration expense. We calculate non-GAAP net income by adding back or removing the following items to or from GAAP net income (loss): stock-based compensation, intangibles amortization, amortization of discount and issuance costs on convertible senior notes, loss on early extinguishment of debt, acquisition-related transaction costs and one-time integration costs, COVID-19 relief bonus for employees, contingent consideration expense and tax benefit of valuation allowance associated with an acquisition. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. The Company considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the Company, exclusive of factors that do not directly affect what we consider to be our core operating performance, as well as unusual events. The Company's management uses these measures to (i) illustrate underlying trends in the Company's business that could otherwise be masked by the effect of income or expenses that are excluded from non-GAAP measures, and (ii) establish budgets and operational goals for managing the Company's business and evaluating its performance. In addition, investors often use similar measures to evaluate the operating performance of a company. Non-GAAP financial measures are presented only as supplemental information for purposes of understanding the Company's operating results. The non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP. Please see the reconciliation of non-GAAP financial measures set forth herein and attached to this release.

Forward-Looking Statements

This news release contains certain forward-looking statements and the statements regarding the proposed acquisition of Five9 by Zoom. These forward-looking statements are made as of the date they were first issued and were based on our current expectations and involve numerous risks and uncertainties that may cause these forward-looking statements to be inaccurate, including risks and uncertainties related to the announcement of the Zoom transaction, the restrictive covenants contained in the definitive agreement with Zoom, and the impact of the announcement of the Zoom transaction on our business and operations. Other risks that may cause these forward-looking statements to be inaccurate include, among others: (i) our quarterly and annual results may fluctuate significantly, including as a result of the timing and success of new product and feature introductions by us, may not fully reflect the underlying performance of our business and may result in decreases in the price of our common stock; (ii) if we are unable to attract new clients or sell additional services and functionality to our existing clients, our revenue and revenue growth will be harmed; (iii) our recent rapid growth may not be indicative of our future growth, and even if we continue to grow rapidly, we may fail to manage our growth effectively; (iv) failure to adequately retain and expand our sales force will impede our growth; (v) if we fail to manage our technical operations infrastructure, our existing clients may experience service outages, our new clients may experience delays in the deployment of our solution and we could be subject to, among other things, claims for credits or damages; (vi) our growth depends in part on the success of our strategic relationships with third parties and our failure to successfully maintain, grow and manage these relationships could harm our business; (vii) we have established, and are continuing to increase, our network of master agents and resellers to sell our solution; our failure to effectively develop, manage, and maintain this network could materially harm our revenues; (viii) adverse economic conditions may harm our business; (ix) the effects of the COVID-19 pandemic have materially affected how we, our clients and business partners are operating, and the duration and extent to which this will impact our future results of operations and overall financial performance remains uncertain; (x) security breaches and improper access to or disclosure of our data or our clients' data, or other cyber attacks on our systems, could result in litigation and regulatory risk, harm our reputation and our business; (xi) we may acquire other companies or technologies, or be the target of strategic transactions, or be impacted by transactions by other companies, which could divert our management's attention, result in additional dilution to our stockholders and otherwise disrupt our operations and harm our operating results; (xii) the markets in which we participate involve numerous competitors and are highly competitive, and if we do not compete effectively, our operating results could be harmed; (xiii) if our existing clients terminate their subscriptions or reduce their subscriptions and related usage, our revenues and gross margins will be harmed and we will be required to spend more money to grow our client base; (xiv) we sell our solution to larger organizations that require longer sales and implementation cycles and often demand more configuration and integration services or customized features and functions that we may not offer, any of which could delay or prevent these sales and harm our growth rates, business and operating results; (xv) because a significant percentage of our revenue is derived from existing clients, downturns or upturns in new sales will not be immediately reflected in our operating results and may be difficult to discern; (xvi) we rely on third-party telecommunications and internet service providers to provide our clients and their customers with telecommunication services and connectivity to our cloud contact center software and any failure by these service providers to provide reliable services could cause us to lose clients and subject us to claims for credits or damages, among other things; (xvii) we have a history of losses and we may be unable to achieve or sustain profitability; (xviii) the contact center software solutions market is subject to rapid technological change, and we must develop and sell incremental and new products in order to maintain and grow our business; (xix) we may not

3

be able to secure additional financing on favorable terms, or at all, to meet our future capital needs; (xx) failure to comply with laws and regulations could harm our business and our reputation; (xxi) we may not have sufficient cash to service our convertible senior notes and repay such notes, if required, and other risks attendant to our convertible senior notes and increased debt levels; (xxii) closing of the proposed transaction with Zoom on anticipated timing or at all (including the risk that the conditions to the transaction are not satisfied on a timely basis or at all or the failure of the transaction to close for any other reason) and terms (including obtaining the anticipated tax treatment, regulatory approvals, required consents or authorizations); and (xxiii) the other risks detailed from time-to-time under the caption 'Risk Factors' and elsewhere in our Securities and Exchange Commission filings and reports, including, but not limited to, our most recent annual report on Form 10-K and quarterly reports on Form 10-Q.
