Fortinet's second-quarter results matter because they capture a pivotal shift in enterprise spending: the convergence of networking and security as customers modernize infrastructure to support AI workloads. Coming off a strong start to 2026, investors were watching whether product momentum, particularly around FortiGate hardware and AI data center security, could be sustained. The quarter also serves as a read on cybersecurity demand durability across industries and geographies. With elevated AI-driven infrastructure investment and rising regulatory pressure on operational technology (OT) security, Fortinet's performance offers a benchmark for how well integrated security platforms are converting these tailwinds into billings, revenue, and margin expansion.
For the second quarter of 2026, ended June 30, Fortinet reported total revenue of $2.0479 billion, a 25.6% increase from $1.63 billion a year earlier and above consensus estimates of roughly $1.89 billion. Product revenue climbed 51.9% to $773 million, while service revenue rose 13.7% to $1.27 billion.
On a GAAP (Generally Accepted Accounting Principles) basis, diluted EPS was $0.82, up from $0.57 a year ago. Non-GAAP EPS, which excludes certain non-cash and one-time items, came in at $0.90, up 40.6% year over year and comfortably ahead of the $0.75 analyst consensus.
Total billings grew 33.4% to $2.37 billion. Secure networking billings rose 34%, OT billings increased more than 55%, Unified SASE (Secure Access Service Edge, a cloud-based architecture combining networking and security) grew 35%, and AI-driven security operations billings advanced 25%. FortiSASE billings more than doubled year over year.
Profitability strengthened meaningfully. Non-GAAP operating margin reached a second-quarter record of 38%, while GAAP operating margin expanded to 33.7%. Operating cash flow was $1.04 billion, and free cash flow of $965.6 million represented a 47.2% margin.
Management raised full-year 2026 revenue guidance to $8.02 billion to $8.18 billion and issued third-quarter revenue guidance of $2.01 billion to $2.10 billion, with non-GAAP EPS guidance of $0.83 to $0.87.

Investor sentiment around Fortinet's earnings has been shaped by the company's accelerating billings and expanding margins, which suggest durable demand for its integrated security platform. The substantial revenue and EPS beats, alongside raised guidance, reinforced confidence that cybersecurity spending tied to AI infrastructure remains a multi-quarter driver rather than a one-off event. Key risk factors that investors continue to weigh include the sustainability of product revenue growth, the pace of service revenue reacceleration, and elevated valuation expectations following the record margins. The balance of strong execution against premium valuation remains a central theme in how the market interprets the results.
Following this report, the forward focus shifts to whether Fortinet can sustain its momentum into the second half of 2026. Management's raised full-year revenue guidance signals confidence, but investors will monitor whether service revenue growth continues to accelerate as stronger product sales flow into attached services and subscriptions.
AI remains a central demand driver. The company highlighted large wins securing AI data centers, suggesting a growing pipeline tied to accelerated computing buildouts. Watch for commentary on the durability of this trend and its impact on average selling prices and FortiGate unit volumes.
Margin and cash flow trends also deserve attention. Record operating margins and surging free cash flow reflect disciplined cost management and improving efficiency, but sustaining this level will depend on revenue mix and continued execution.
Finally, industry dynamics such as the convergence of networking and security, OT security adoption driven by regulatory requirements, and data sovereignty demands in EMEA (Europe, the Middle East, and Africa) will shape the demand environment. Investors should watch upcoming quarterly results and guidance for evidence that these themes continue translating into billings growth without pressuring profitability.
