Summary and Conclusions
- Fortinet enters Q2 2026 earnings with strong momentum: Q1 2026 saw revenue up +20% YoY, product revenue up +41% YoY, and billings up +31% YoY, all exceeding the high end of guidance.
- Guidance for Q2 and FY26 has been raised: Management now expects FY26 revenue of $7,710M–$7,870M (+15% YoY at midpoint), billings of $8,800M–$9,100M (+18%), and service revenue of $5,090M–$5,150M (+12%).
- Key drivers are AI-related demand, OT security, and SASE adoption: Management repeatedly highlights AI as a secular tailwind, with OT billings up over 70% in Q1 and Unified SASE billings up 31%.
- Q2 2026 faces a tough comparable: Q2 2025 revenue was $1,626M (+14% YoY at the time), so the current consensus ($1,886M) implies +16% YoY growth on top of a strong prior-year comp.
- Margins remain robust: Q1 2026 non-GAAP operating margin was 36%, and Q2 guidance is 33–35%. Gross margin is guided at 79.5–80.5%.
- Supply chain and pricing: Management is proactively managing memory/component cost inflation with selective price increases (low single-digit impact in Q1), but maintains a policy of adjusting prices to preserve margin, not expand it.
- Service revenue acceleration expected in 2H26: Service billings and deferred revenue trends are positive, but revenue recognition lags hardware sales.
Most important factors to watch in Q2 2026:
- Can Fortinet sustain >30% billings growth and >40% product revenue growth, or will growth moderate?
- Is AI/OT/SASE demand broad-based and durable, or is there evidence of early ordering or pull-forward?
- How are margins holding up amid supply chain pressures and price adjustments?
- Are service revenue and billings accelerating as expected, confirming the leading indicator from hardware sales?
- Any signs of channel inventory build or changes in customer buying behavior due to macro or pricing?

What to Watch for This Quarter
1. Sustainability of Growth
- Q1 2026 saw exceptional growth in product revenue (+41%) and billings (+31%). The key question is whether this pace can be sustained, especially given a tough comp in Q2 2025 (+14% revenue growth last year).
- Management attributes growth to AI-driven demand, OT security, and SASE adoption, with specific mention of large enterprise and sovereign SASE deals.
2. AI and OT Security Demand
- Management repeatedly highlights AI as a secular tailwind, driving both infrastructure build-outs and internal segmentation needs.
- OT security billings grew over 70% in Q1 2026, and management expects this to remain a high-growth area.
3. SASE and Sovereign SASE Momentum
- Unified SASE billings grew 31% in Q1 2026, with 18% of large enterprise customers now having purchased FortiSASE (+45% YoY).
- Fortinet claims a unique position in Sovereign SASE, especially in EMEA, and expects this to be a major TAM expansion driver.
4. Margins and Pricing
- Non-GAAP operating margin guidance for Q2 is 33–35%, with gross margin at 79.5–80.5%.
- Management is actively managing component cost inflation with selective price increases (low single-digit impact in Q1), but is committed to maintaining—not expanding—margins.
5. Service Revenue Acceleration
- Service billings grew 27% in Q1 2026, and deferred revenue grew 15%. Management expects service revenue growth to pick up in 2H26 as hardware sales convert to services.
- Watch for confirmation of this trend in Q2 and any commentary on attach rates or renewal cycles.
6. Supply Chain and Inventory
- Fortinet maintains ~6 months of inventory and direct supplier relationships, which management claims is a competitive advantage in the current environment.
- No evidence of channel stuffing or early ordering in Q1, but this remains a risk to monitor.
7. Customer Mix and Upsell
- Large enterprise deals and cross-sell/upsell into existing customers are key growth drivers.
- Management notes that 1/3 of firewall revenue comes from large firewalls (data center), 1/3 from mid-size, and 1/3 from small.
Last Year’s Performance and Comparables
- Q2 2025 was a strong quarter: Revenue grew +14% YoY, product revenue +13%, billings +15%. This sets a high bar for Q2 2026, especially as consensus expects +16% revenue growth.
- FY25 actuals: Revenue $6,800M (+14%), product revenue $2,218M (+16%), billings $7,554M (+16%), non-GAAP op margin 35.5%, non-GAAP EPS $2.76.
- Growth in FY25 was driven by SASE, SecOps, and OT security, with Unified SASE & SecOps billings up 24%.
Management Commentary — Recent Tone
- On AI and OT: "AI is a tailwind to drive the growth... we see the AI accelerate the convergence of our network and network security... OT grow like 70%... very, very strong growth because OT really like secured pretty much the bottom few layer of the AI 5-layer cake."
- On SASE: "Unified SASE billing grew 31%... our differentiation is powered by 3 key advantages: single operating system across next-gen firewall, SD-WAN and SASE, our owned global cloud infrastructure... and our much larger total addressable market especially in sovereign and private SASE."
- On pricing and supply chain: "We are proactively managing memory/component cost inflation with selective price increases... maintain a policy of adjusting prices to preserve margin, not expand it."
- On service revenue: "Service billings growth, deferred revenue and SecOps ARR growth together with accelerating product revenue as leading indicators of future services revenue."
