$FTNT · Fortinet, Inc.
Fortinet reported Q3 FY2026 results with revenue of $2.078B (+20% YoY), product revenue of $765M (+37% YoY), and billings of $2.34B (+29% YoY). GAAP diluted EPS was $0.86 and non-GAAP diluted EPS was $0.91. The company raised FY2026 revenue guidance to ~20% YoY growth ($8.125B–$8.215B) and increased its share buyback authorization by $1.2B to a $2B remaining authorization. However, Q4 guidance for revenue ($2.155B–$2.245B) and non-GAAP EPS ($0.93–$0.95) came in below consensus, triggering a severe after-hours selloff.

Extended-hours trading shows FTNT at $136.77, down 21.43% from the $174.08 regular close, erasing roughly $27B in market cap. The selloff reflects a sharp negative reaction to Q4 guidance that disappointed despite strong Q3 beats on revenue, billings, and EPS.
A $127B cybersecurity leader beating Q3 across revenue, billings, and EPS yet losing over a fifth of its value after-hours on a Q4 guide-down is a textbook example of how forward expectations dominate earnings reactions in high-multiple tech.
Fortinet's 37% product revenue growth and AI-security positioning (NVIDIA OpenShell partnership, FortiGuard Inline AI Security Service) underscore cybersecurity's shift toward AI-driven threats. The post-earnings selloff mirrors recent pattern of high-valuation security names getting punished on guidance even when current-quarter results exceed expectations.
Forward-looking risks cited include macroeconomic headwinds from inflation, interest rates, and reduced IT spending; supply chain challenges; and geopolitical risks from conflicts in Ukraine, Middle East, and China-Taiwan tensions that could disrupt sales or operations.
