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, acquisition and related transaction costs and one-time integration costs, and lease amortization for finance leases. We calculate adjusted EBITDA by adding back or removing the following items to or from GAAP net income: depreciation and amortization, stock-based compensation, interest expense, interest income and other, acquisition and related transaction costs and one-time integration costs, lease amortization for finance leases, costs related to reduction in force plans, one-time expenses related to strategic consulting services for operational review, other cost-reduction and productivity initiatives, one-time expenses related to advisory services for long-term strategy and growth, legal fees related to the securities class action, office closure lease termination costs, impairment charge related to consolidation of corporate headquarters, and provision for income taxes. We calculate non-GAAP operating income by adding back or removing the following items to or from GAAP income from operations: stock-based compensation, intangibles amortization, acquisition and related transaction costs and one-time integration costs, one-time expenses related to strategic consulting services for operational review, other cost-reduction and productivity initiatives, one-time expenses related to advisory services for long-term strategy and growth, legal fees related to the securities class action, office closure lease termination costs, and impairment charge related to consolidation of corporate headquarters. We calculate non-GAAP net income by adding back or removing the following items to or from GAAP net income: stock-based compensation, intangibles amortization, amortization of discount and issuance costs on convertible senior notes, exit costs related to closure and relocation of Russian operations, acquisition and related transaction costs and one-time integration costs, one-time expenses related to strategic consulting services for operational review, other cost-reduction and productivity initiatives, one-time expenses related to advisory services for long-term strategy and growth, legal fees related to the securities class action, office closure lease termination costs, and impairment charge related to consolidation of corporate headquarters. For the periods presented, these adjustments from GAAP net income to non-GAAP net income do not include any presentation of the net tax effect of such adjustments given our significant net operating loss carryforwards. 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 in this release. Forward-Looking Statements This news release contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including the statements in the quote from our Chairman and Chief Executive Officer, including statements regarding Five9's market position, platform breadth, current team and strategy, and new product releases, and the expected positive impact of these factors, and the third quarter and full year 2026 financial projections and expectations set forth under the caption “Business Outlook,” that are based on our current expectations and involve numerous risks and uncertainties that may cause these forward-looking statements to be inaccurate. Risks that may cause these forward-looking statements to be inaccurate include, among others: (i) the impact of adverse economic conditions, including the impact of macroeconomic challenges, global tariff increases and potential future increases and announcements regarding same, continued inflation, uncertainty regarding consumer spending, high interest rates, fluctuations in currency rates, the impact of current and potential global conflicts, and other factors, may harm our business; (ii) if we are unable to attract new customers or sell additional services and functionality to our existing customers, our revenue and revenue growth will be harmed; (iii) if our existing customers terminate their subscriptions or reduce their subscriptions and related usage, or fail to grow subscriptions at the rate they have in the past or that we might expect, our revenues and gross margins will be harmed and we will be required to spend more money to grow our customer base; (iv) because a significant percentage of our revenue is derived from existing customers, downturns or upturns in new sales will not be immediately reflected in our operating results and may be difficult to discern; (v) if we fail to manage our technical operations infrastructure, our existing customers may experience service outages, our new customers may experience delays in the deployment of our solution and we could be subject to claims for credits or damages, among other things; (vi) if we are unable to attract and retain highly skilled leaders and other employees, our business and results of operations may be harmed; (vii) as AI solutions will likely perform an increasing proportion of contact center interactions, if we are unable to replace decreases in subscription revenue from licenses with revenue from the sale of additional AI solutions, our revenue, results of operations and business will be harmed; (viii) further development of our AI solutions may not be successful, may not achieve market acceptance or compete effectively against our competitors, and may result in reputational harm and our future operating results could be materially harmed; (ix) the AI technology and features incorporated into our solution include new and evolving technologies that may present both legal and business risks; (x) we have established, and are continuing to increase, our network of technology solution distributors and resellers to sell our solution; our failure to effectively develop, manage, and maintain this network could materially harm our revenues; (xi) 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; (xii) our historical 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; (xiii) failure to adequately retain and expand our sales force will impede our growth; (xiv) the use of AI by our workforce may present risks to our business; (xv) the contact center software solutions market is subject to rapid technological change, and we must develop and sell incremental and new solutions in order to maintain and grow our business; (xvi) 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; (xvii) the markets in which we participate involve a high number of competitors that is continuing to increase, and if we do not compete effectively, our operating results could be harmed; (xviii) we continue to expand our international operations, which exposes us to significant macroeconomic and other risks; (xix) security breaches, cybersecurity incidents, and improper access to, use of, or disclosure of our data or our customers’ data, or other cyber-attacks on our systems, could result in litigation and regulatory risk, harm our reputation, our business or financial results; (xx) 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 or use a significant amount of our cash resources and otherwise disrupt our operations and harm our operating results; (xxi) 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; (xxii) we rely on third-party telecommunications and internet service providers to provide our customers 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 customers and subject us to claims for credits or damages, among other things; (xxiii) prior to 2025, we had a history of losses and we may be unable to sustain profitability; (xxiv) our stock price has been volatile, may continue to be volatile and may decline, including due to factors beyond our control; (xxv) we may not be able to secure additional financing on favorable terms, or at all, to meet our future capital needs; (xxvi) failure to comply with laws and regulations could harm our business and our reputation; (xxvii) 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; (xxviii) risks that we may not execute repurchases in full, under our announced stock repurchase program, or may not achieve the intended benefits therefrom; and (xxix) 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.
