Valuation metrics and multiples for Zscaler Inc

The steep one-day sell-off following fiscal Q3 2026 results has immediate consequences for valuation, as a 32% price decline in a single session can materially compress forward revenue and earnings multiples, according to trading data summarized by GuruFocus on 06/04/2026.GuruFocus as of 06/04/2026

GuruFocus reported on 06/04/2026 that Zscaler guided fiscal 2027 revenue growth to a range of 16% to 17%, below the roughly 19% to 20% growth previously anticipated by the market, a change that typically feeds into lower implied long-term growth rates in discounted cash flow models and can therefore weigh on valuation multiples even if near-term earnings remain solid.GuruFocus as of 06/04/2026

Conclusion

Zscaler Inc’s latest share-price volatility on the Nasdaq reflects investor reassessment of the company’s medium-term revenue trajectory after fiscal Q3 2026 results and fiscal 2027 guidance, as highlighted by GuruFocus on 06/04/2026. While the company delivered solid quarterly performance, the updated growth outlook for fiscal 2027 at 16% to 17% revenue expansion versus roughly 19% to 20% previously expected underscores how sensitive valuation can be to changes in long-range assumptions for a high-growth cybersecurity name.
