Fortinet and Tenable shares fall despite strong third-quarter earnings

Shares of network security firm Fortinet Inc. dropped 26% in after-hours trading despite reporting third-quarter financial results that exceeded analyst expectations, with further coverage provided by Silicon Angle.

Fortinet reported adjusted earnings of 91 cents per share on revenue of $2.08 billion, surpassing analyst projections of 86 cents per share and $2.06 billion in revenue. Despite these gains, investors reacted negatively to a deceleration in revenue growth and a reduction in the company's full-year service revenue forecast. This sentiment triggered a broader selloff across the cybersecurity sector, impacting firms such as Palo Alto Networks Inc., CrowdStrike Holdings Inc. and Zscaler Inc., which saw shares decline between 6% and 7%.

Tenable Holdings Inc. also experienced a share price drop of more than 5% after hours, despite beating earnings estimates with 63 cents per share. Conversely, Gen Digital Inc. saw its shares rise nearly 6% after reporting strong results for its fiscal 2027 second quarter. Industry analysts suggest that while demand for security remains robust, particularly as artificial intelligence introduces new attack surfaces, market participants are increasingly focused on growth consistency and forward-looking guidance rather than historical performance metrics.
