Financial Performance:

• Total revenue grew 20% YoY to $2.08 billion, with product revenue surging 37% to $765 million and service revenue rising 13% to $1.31 billion.
• Total billings increased 29% YoY to $2.34 billion, driven by a 51% growth in deals exceeding $1 million and a 31% rise in SASE firewall billings.
• Non-GAAP gross margin was 79.6% and Non-GAAP operating margin reached a record 38.2%, up 130 basis points YoY.
• Non-GAAP EPS rose 23% to $0.91, while GAAP EPS grew 39% to $0.86.
• Free cash flow expanded 52% to $865 million in Q3, with year-to-date FCF up 74% to $2.84 billion; adjusted FCF margin was 44%.
• Deferred revenue grew 19% YoY, with short-term deferred revenue up 14.5%, marking the highest growth in five quarters.
• Product gross margin compression occurred due to the exhaustion of lower-cost inventory buffers and rising component costs, partially offset by service margin improvements.

Guidance and Future Outlook:

• Raised full-year 2026 billings guidance to $9.568–$9.718 billion (midpoint +28% growth) and revenue to $8.125–$8.215 billion (midpoint +20% growth).
• Raised full-year Non-GAAP EPS guidance to $3.54–$3.58 and Non-GAAP operating margin to 36.5–37.5%.
• Q4 2026 guidance: Billings $2.775–$2.925B, Revenue $2.155–$2.245B, Non-GAAP EPS $0.93–$0.95.
• Outlook for 2027 indicates billings and revenue growth expected to outpace the addressable market, with service revenue growth accelerating relative to 2026.
• Confidence expressed in sustained growth through 2027 driven by AI security demand, SASE expansion, and sovereign architecture trends.
• Board approved a $1.2 billion increase to the stock repurchase program, raising remaining authorization to $2 billion.

Business Segments and Product Lines:

• SASE firewall pillar grew 31%, making Fortinet the fastest-growing vendor in the space, nearly doubling the market growth rate.
• Operational Technology (OT) billings grew nearly 40%, with major wins in transportation and retail sectors securing mission-critical infrastructure.
• AI-driven security operations billings grew 15%, fueled by platform consolidation and the launch of new FortiGuard inline AI security services.
• Product mix shift toward high-performance models increased ASPs, though lead times for certain components are lengthening.
• New "FortiLink SASE" service allows Fortinet APs and switches to act as SASE hardware agents, overlaying cloud security on existing hardware.
• Offerings now cover four key AI security areas: network-level SASE, data center/AI factory GPU protection, endpoint/identity integration, and automated SOC response.

Market and Competitive Landscape:

• Market demand is driven by the convergence of IT and OT, the threat of AI-powered attacks, and the need for sovereign/compliant architectures, particularly in Europe and public sectors.
• Fortinet is the only vendor integrating firewall, SASE, and AI security components into a single OS, providing a unified architecture advantage.
• The company holds the largest share in the SASE firewall market and is growing faster than the 16% estimated market rate.
• Competitors face supply chain constraints and longer lead times, whereas Fortinet leverages owned ASIC technology and direct manufacturer relationships.
• Customers are moving away from point solutions toward integrated platforms to manage the complexity of AI data centers and decentralized workforces.

Risks and Challenges:

• Service revenue growth in Q3 faced headwinds due to delayed activation and ramp-up periods associated with new large enterprise deals and complex consolidation agreements.
• Supply chain constraints persist with increasing lead times for components, though inventory buffers have normalized.
• Pricing increases have stabilized; while ASPs are rising due to model mix, cost pressures from components are impacting product gross margins.
• Customer asset "sweating" is less prevalent as new AI vulnerabilities necessitate hardware upgrades rather than extending the lifecycle of legacy gear.
• Large enterprise deals may involve longer recognition periods for services due to enterprise agreement structures and phased rollouts.

Management Commentary and Tone:

• Management expressed high confidence and excitement regarding the "excellent third quarter results" and the critical role of network security in the AI era.
• Tone was optimistic, emphasizing that the current AI-driven security cycle is more durable and impactful than post-2012 or post-pandemic cycles.
• CEO Ken Zee highlighted the company's unique architectural advantage and the structural necessity of high-performance security for AI workloads.
• CFO Christiana Olgaard noted that while service revenue recognition timing caused a temporary miss, leading indicators (billings and deferred revenue) signal a positive trajectory.
• Management reinforced the strategy of disciplined cost management to maintain high profitability and cash generation.

Analyst Questions and Answers:

• AI and SASE Growth: Ken Zee confirmed SASE firewall growth is outpacing the market, driven by the need to secure AI traffic and the ability to enforce security at the network level.
• Service Revenue Timing: Analysts asked about the service growth trajectory; management clarified that Q3 delays were a timing issue related to large deal ramp-ups, with revenue expected to accelerate in 2027.
• Pricing and Supply Chain: Questions regarding price increases were answered that the benefit is ~10% to billings, but costs are rising; margins are expected to stabilize as price and cost increases balance out.
• OT Security: Confirmed broadening customer base in OT, with specific wins in transportation and retail sectors due to unified networking and security capabilities.
• Open-Weight Models: Identified that the shift to open-weight models increases demand for internal network security and high-speed inspection within data centers.
• SASE Bundles: Early adoption of SASE bundles shows a modest pricing uplift, though full adoption across the SD-WAN base will take time.

Other Key Points:

• A specific large AI company expanded its Fortinet deployment across five additional data centers to secure frontier model workloads, citing the need for high throughput and resilience.
• A large U.S. retailer standardized its 1,500-store footprint using Fortinet to improve network performance and reduce costs.
• A large transportation company selected Fortinet in an eight-figure competitive win to secure OT infrastructure, consolidating routing, 5G, and deep inspection into one appliance.
• Management reiterated that the "first quarter of 2026" marked the trough for service revenue growth rates.
• The "FortiCare" service infrastructure is increasingly leveraging AI to assist service personnel, improving local support capabilities.
