Five9 pairs sticky enterprise CCaaS subscriptions with 78% AI revenue growth and a discounted valuation, but margin recovery and AI-driven seat cannibalization will determine whether its long-term upside is realized.
Overview
Five9 sells cloud-native contact-center software and AI-enabled customer-experience tools to mid-market and enterprise customers, replacing legacy hardware with scalable voice and digital-channel operations. Subscriptions are approximately 83% of revenue, supported by one-to-five-year contracts; telecommunications usage contributes about 11% and professional services 6%. The platform’s voice reliability, CRM integrations, native AI, and high switching costs underpin a 107% dollar-based retention rate. Q2 2026 revenue was $312.44 million, up 10.3% year over year and $5.83 million above consensus. Subscription revenue grew 14.4%, and AI revenue increased 78% to $39 million, while non-GAAP gross margin fell 160 basis points to 61.4% and EBITDA margin declined to 22.4%. Management reaffirmed FY 2026 revenue guidance of $1.260–$1.272 billion and non-GAAP EPS of $3.22–$3.30, while raising its AI growth target to at least 60%. At $34.36, the stock trades at 2.18x forward sales and 10.54x forward non-GAAP earnings, below cited sector medians of 4.50x and 22.00x. **The opportunity is AI monetization layered onto sticky cloud subscriptions; the key near-term test is margin recovery.** Catalysts include scaling AI beyond a $150 million run rate, converting large contracts, and Acqueon cross-selling.
