Fortinet posts Q3 2026 earnings beat, raises guidance but shares plunge

Fortinet reported Q3 2026 revenue of $2.08 billion, up 20% year‑over‑year, and adjusted earnings of $0.91 per share, beating analyst forecasts. The company raised its Q4 revenue outlook to $2.155‑$2.245 billion and full‑year revenue guidance to $8.125‑$8.215 billion. Despite the beat, the stock fell sharply in after‑hours trading.

The share‑price decline shows investor concern over the slower revenue growth and guidance, creating short‑term downside risk despite the earnings beat. The raised guidance sets higher expectations for Q4 and FY 2026, affecting valuation models that rely on revenue and earnings forecasts.
