Fortinet (FTNT) Q2 2025 earnings review
Billings Accelerate and Guidance Raised as SASE & Refresh Cycle Drive Momentum
Fortinet delivered a strong Q2, beating expectations on both Billings and EPS and raising its full-year billings guidance by $100 million. The results were driven by accelerating momentum in its strategic growth pillars, Unified SASE (+21% billings growth) and SecOps (+31%), which now comprise 35% of total billings. This successful cross-selling into the install base is complemented by the ongoing firewall refresh cycle, which management states is now 40-50% complete. While operating margin remains robust at 33.1%, it has normalized from recent peaks due to increased investments, but the overall performance signals a successful strategic transition and a healthy demand environment.
🐂 Bull Case
Billings growth accelerated for the fourth consecutive quarter to 15.4% YoY. Confidence in the second half led management to raise the midpoint of full-year billings guidance by $100 million, a key indicator of future revenue.
The strategic pillars are firing on all cylinders, with Unified SASE and SecOps billings growing 21% and 31% respectively. Their increasing contribution to the total (now 35%) validates the platform cross-sell strategy.
Management confirmed being 40-50% through the 2026 end-of-service cohort, providing a multi-quarter tailwind for the core product business and opportunities to upsell new services onto new hardware.
🐻 Bear Case
Non-GAAP Operating Margin of 33.1% was strong but declined 200 basis points year-over-year. Increased investments in sales headcount and acquisitions suggest margins may have peaked after an exceptional FY24.
While YoY growth remains strong, the headline Unified SASE ARR figure of $1.15 billion was flat sequentially compared to Q1. This could signal maturation in parts of the SASE bundle, like SD-WAN.
⚖️ Verdict: 🟢
Bullish. The acceleration in billings, the primary forward-looking indicator, is the most important takeaway. The successful execution of the SASE/SecOps cross-sell strategy is creating powerful new growth engines, while the firewall refresh provides a durable foundation. The company is effectively navigating its strategic pivot while maintaining elite profitability.
Key Themes
Growth Pillars Firing: SASE & SecOps
Fortinet's pivot to platform sales is paying off. Unified SASE billings grew 21% and SecOps billings grew 31%, significantly outpacing the company average. Together, these pillars now represent 35% of total billings (24% SASE, 11% SecOps). The customer journey is clear and effective: over 90% of large enterprise FortiSASE customers began with Fortinet's SD-WAN solution, demonstrating a powerful land-and-expand motion built upon the unified FortiOS operating system.
Firewall Refresh Cycle Progressing Steadily
Management provided a key update, stating they are now 40% to 50% through the large 2026 end-of-service upgrade cycle. This refresh provides a durable tailwind for the core Secure Networking business, evidenced by Product Revenue growth stabilizing at 13% YoY. The updated full-year guidance includes a $50M shift from service to product revenue, signaling confidence in hardware demand for the rest of the year.
Contradictory Signal: Unified SASE ARR Flat Sequentially
While the YoY SASE growth narrative is strong, the headline Unified SASE ARR figure of $1.15 billion was flat compared to Q1 2025. On the call, management clarified this was due to slower growth in mature components of the bundle (like SD-WAN), while the newer SSE component grew its ARR over 100%. However, the flat total ARR figure is a crucial data point that contradicts the simple growth story and warrants monitoring to ensure the overall SASE engine isn't losing momentum.
Strong Enterprise and Large Deal Momentum
Fortinet continues to win with large customers who are consolidating their security stack. The total dollar value of deals greater than $1 million grew by 51% YoY. This indicates success in platform selling and displacing competitors. The financial services vertical was a standout, with billings growth of over 30%, demonstrating traction with sophisticated security buyers.
Operating Margin Normalizes Amid Investment
The non-GAAP operating margin of 33.1% was strong and beat guidance, but it was down 200 bps from the prior year's 35.1%. Management attributed the decline to increased investments in sales headcount, costs from recent acquisitions, and FX headwinds. While still at an elite level, the trend suggests margins are normalizing from the record peaks seen in late FY24 as the company invests for future growth.
AI Security Portfolio Taking Shape
Management highlighted its long-term investment in AI, with over 500 issued and pending AI patents. The company is productizing this R&D with solutions like FortiAI-Protect for threat detection, FortiAI-Assist for task automation, and FortiAI-SecureAI for protecting AI infrastructure. These offerings are cited as the 'fastest growing part' of the business, representing a new, high-potential growth vector.
Other KPIs
Accelerating. Billings, a key indicator of future revenue, grew 15.4% YoY, marking the fourth consecutive quarter of accelerating growth. This was driven by strength in large enterprise deals and the SASE and SecOps pillars. The performance prompted a $100M raise to the full-year billings guidance midpoint.
Cash generation in the first half of the year was very strong, representing a margin of 40%. After $168M in infrastructure investments during Q2, the company still repurchased $401M of stock, ending the quarter with a remaining authorization of $1.6 billion.
Remaining Performance Obligations (RPO) grew 12% to $6.64B, while current RPO grew faster at 15% to $3.45B, in line with billings growth. Annual Recurring Revenue (ARR) from the growth pillars remains robust, with Unified SASE at $1.15B (+22% YoY) and SecOps at $463M (+35% YoY).
Guidance
Slightly decelerating. The midpoint of $1.80B implies 13.8% YoY growth. This represents a slight sequential deceleration from Q2's 15.4% growth but indicates continued healthy demand.
Stable. The midpoint of $1.70B implies 13.0% YoY growth, which is consistent with the growth rates of the last three quarters.
Accelerating Outlook. The midpoint was raised by $100M to $7.4B. This implies full-year growth of 13.3%, signaling management's increased confidence in demand for the second half of the year.
While the total revenue guidance range for the year was maintained, management adjusted the mix by shifting $50 million from service to product revenue. This directly reflects higher confidence in the ongoing firewall refresh cycle.
