Business-Segment Outlook:

• SASE Firewall: Anticipated to grow significantly, currently outpacing the market growth rate of ~16%. New "FortiGuard Inline AI Security" services launched to transform gateways into real-time AI enforcement points.
• Product Revenue: Demand driven by shifts to higher-performing models (lifting ASPs) and network upgrades for AI infrastructure. Product growth expected to continue exceeding market rates in 2027.
• Service Revenue: Q1 2026 marked the trough for growth rate; led by robust 26% service billing growth and 19% total deferred revenue growth. Expectation of improved growth in 2027 as large enterprise deal activations ramp up and deferred revenue converts.
• OT (Operational Technology): Billings grew ~40%; outlook remains strong as customers rush to segment networks and shield legacy machinery from AI-armed attackers.
• Geography: Sovereign SASE solutions driving demand in European enterprises and the global public sector; U.S. large enterprise business contributing outsized deal value growth (+51% for deals >$1M).
• Backlog/Pipeline: Pipeline building for SASE firewall use cases; new FortiGuard services expected to be highly relevant for existing and new customers.

Market and Competitive Outlook:

• Demand Trends: AI-driven threat landscape (agentic attacks, AI-discovered vulnerabilities) driving structural necessity for high-performance security; demand remains strong with no signs of slowdown.
• Pricing Strategy: Pricing increases stabilized (approx. 10% benefit realized so far) but have not yet improved further; company maintains strategy of matching price increases to cost increases to protect gross margins.
• Market Share: Fortinet is the fastest-growing SASE firewall vendor (nearly double market growth rate); largest SASE firewall player in the space.
• Structural Shifts: Convergence of networking and security; merging of IT and OT domains; shift from point solutions to integrated platforms; rise of sovereign/compliant architectures.
• Competitive Advantage: Only vendor with a unified OS for firewall, SASE, and hybrid mesh; proprietary ASIC technology; ability to deliver on-premise sovereign SASE alongside cloud SASE.

Macro / Industry Outlook:

• AI Infrastructure: Massive growth in AI traffic and GPU clusters requiring high-performance protection across data centers and hybrid clouds.
• Regulatory/Geopolitical: Sovereignty is a prominent driver in Europe and the public sector; enterprises prioritizing sovereign compliant architectures.
• Supply Chain: Component lead times increasing; inventory management shifting from on-hand buffer (6 months) to normal sourcing levels; some pricing pressures expected but stabilized.
• Customer Behavior: Enterprises moving away from "asset sweating" due to new AI vulnerabilities and lack of support for new functions on older hardware; shift toward high-end appliances.

Strategic Initiatives:

• Product Launches: FortiGuard Inline AI Security services (launched Q3 2026) and FortiLink SASE services (positioning AP/Switch as SASE agents).
• Capacity/Additions: Investing in AI capability and functions within FortiOS and FortiGuard; expanding sovereign SASE offerings.
• M&A/Partnerships: Leveraging extensive partner channel for deployment; direct service team engagement for large-scale rollouts (e.g., 4,000 store retailer).
• Capital Allocation: $1.2B increase in stock repurchase authorization to return capital while investing in growth pillars.

Risks and Headwinds to Outlook:

• Revenue Recognition Delays: Large enterprise deals and expansion contracts may involve ramped service activations, delaying revenue recognition relative to billing (impacted Q3 service growth).
• Supply Constraints: Increasing component lead times and potential cost increases affecting product gross margins.
• Product Mix Shifts: Increased focus on high-end product-heavy sovereign deployments may lower service attach rates in the near term.
• External Uncertainties: Actual results may differ materially from projections due to risks and uncertainties related to AI threat evolution, supply chain stability, and regulatory changes (refer to SEC filings).

Management Tone on the Future:

• Confidence Level: High confidence in continued momentum and ability to grow faster than the market in 2027; describes the current AI security cycle as "bigger" and more "durable" than post-COVID cycles.
• Caveats/Revisions: Raised FY2026 guidance for billings, revenue, and margins; explicitly noted Q1 2026 was the trough for service growth with an expectation of acceleration in 2027.
• Market Positioning: Strong belief that network security is the "critical foundation" of AI security; views the current threat environment as a structural, long-term demand driver.

Miscellaneous:

• Stock Count: Guided at 741M–745M for FY2026 and 741M–743M for Q4 2026.
• Investor Conferences: Management to attend BMO, UBS, and Barclays conferences in Q4 2026.
