F5, INC. Q4 FY2026 earnings call

• Strategic Megatrends: Management highlighted three core drivers reshaping customer behavior: Hybrid Multicloud Adoption, an Expanding Threat Landscape, and Accelerating AI Inference. These trends are directly fueling demand for F5’s converged platform.
• AI Security Momentum: F5 launched its AI-powered Web Application Firewall (WAF) in March, gaining over 300 customers by Q4, with more than 75% operating in blocking mode. The company demonstrated real-time protection against critical vulnerabilities (e.g., PHP flaws) without requiring new rules, emphasizing runtime security over traditional patch cycles.
• Platform Consolidation Wins: A key strategic theme is displacing fragmented incumbent vendors. Examples include an eight-figure win with a North American financial institution where F5 replaced four competitors (two ADCs, two CDN/security tools) with a unified on-premises and cloud platform. Similar wins occurred with an Asian central bank and a European financial institution.
• AI Inference Growth: Direct AI use cases (data delivery, runtime security, factory load balancing) saw bookings exceed $100 million in FY26, up nearly 300% year-over-year. Active direct AI customers grew 4x to over 200. Notable wins include protecting 500 AI models for a global infrastructure leader and optimizing GPU utilization for telecom providers Indosat and Telenor.
• Operational Efficiency & Innovation: F5 leveraged AI to remediate thousands of codebase vulnerabilities, accelerating engineering fixes that previously took years. The launch of 'F5 Insight' has been adopted by over 200 customers for automated fleet management and upgrade orchestration.
• Market Recognition: F5 was named a leader in SecureIQ Labs’ Cloud WAP report, IDC’s market scape for WAP platforms, and Gartner recognized it as one of only two 'market shapers' in AI application security within four months of launching its AI security platform.

In the fourth quarter of fiscal 2026, F5 delivered total revenue of $917 million, representing a 13% year-over-year increase. Product revenue was the primary growth driver, totaling $510 million and accounting for 56% of total revenue, with a robust 23% year-over-year growth rate. This marks the ninth consecutive quarter of double-digit product revenue growth. Services revenue contributed the remaining 44%, reaching $408 million with a modest 3% year-over-year increase. On a full-year basis, total revenue reached $3.4 billion (11% growth), with product revenue growing 19% to reflect strong demand across hybrid multicloud and security solutions.

• FY27 Revenue Outlook: Management guided for 8-9% revenue growth for fiscal 2027, maintaining a solid foundation despite a high bar set by FY26's exceptional performance.
• Product Revenue: Expects a third consecutive year of double-digit product revenue growth in FY27, driven by hybrid multicloud adoption, security demand, and AI inference.
• Gross Margin: Non-GAAP gross margin is expected to range between 80.5% and 82.5% for FY27, reflecting higher component costs.
• Services Growth: Low to mid-single-digit growth is anticipated for services revenue in FY27.
• Q1 FY27 Specifics: Revenue is guided at $875-$895 million. Non-GAAP gross margin is expected at approximately 81.5%-82.5%. Non-GAAP EPS is projected at $4.25-$4.37 per share.
• Cash Flow & Capital Return: Inventory builds are strategically increasing to secure supply for FY27 systems demand. Bonus payments from FY26 will occur in November 2026, impacting Q1 cash flow. Share repurchases are prioritized, with an additional $1.5 billion authorized, aiming to return at least 50% of annual free cash flow to shareholders.

• Supply Chain Constraints: While inventory levels are being strategically increased to mitigate risk, long lead times for components (particularly memory and storage) remain a potential vulnerability. Management acknowledges ongoing monitoring needs for component shortages.
• Competitive Displacement Complexity: Although F5 is winning consolidated deals, the transition from fragmented point products to a single platform requires significant customer effort and carries execution risk if not managed properly.
• Rapidly Evolving Threat Landscape: The collapse of mean time to exploit (negative seven days) and the surge in vulnerabilities (up 50% YoY) create pressure on customers to adopt faster, AI-driven security solutions, requiring continuous innovation from F5 to maintain differentiation.
• AI Model Security Limitations: Frontier model providers cannot adequately secure their own models or agents; however, reliance on open-weight models introduces variability in safety behaviors, necessitating rigorous third-party runtime protection which F5 must continuously adapt to provide.

Q: Matt Hedberg asked about the addressable TAM for AI use cases and the scalability of the current booking trajectory. / A: Francois Locoh-Donou stated the AI TAM is projected to reach $11 billion by 2030, up from ~$1 billion today. AI data delivery is the largest segment, driving ADC selection due to features like S3/MCP protocol support. AI security is early but gaining traction as enterprises need hybrid-cloud guardrails for open-weight and frontier models. AI factory load balancing is nascent but growing as sovereign AI players shift from bare-metal GPU offerings to token-as-a-service, requiring tenant isolation and governance.
