Zscaler Inc. (NASDAQ: ZS) is now trading at a forward 12-month price-to-sales ratio of 5.27x, a level that represents a significant discount to the broader internet software industry average of 14.75x.

The valuation compression comes despite ZS continuing to report strong operating metrics.

ARR grew 25% to $3.53 billion, and remaining performance obligations rose approximately 30% to $6.5 billion. Non-GAAP operating income increased 33% year over year, and management highlighted that ZS achieved "Rule of 55" performance year to date, combining strong revenue growth with healthy free cash flow margins.

ZS's AI-focused product offerings have also gained traction, with AI Protect bookings surpassing $100 million over the trailing 12 months. ZS has formed partnerships with Anthropic and OpenAI and announced the planned acquisition of Symmetry Systems to strengthen its position in securing AI agents and enterprise data environments. The Zero Trust Everywhere customer count grew from more than 550 in the second quarter to over 700 in the third quarter of fiscal 2026.

The stock's sell-off was precipitated by preliminary fiscal 2027 guidance indicating revenue and ARR growth of 16% to 17%, a deceleration from the prior mid-20s growth rate. ZS currently carries a Zacks Rank of 3 (Hold).
