[Form 4] Zscaler, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Zscaler (Nasdaq: ZS) filed a Form 4 reporting a small insider transaction by its founder, CEO & Chairman, Jagtar Singh Chaudhry. On June 17, 2025 the executive sold 2,849 common shares at a weighted-average price of $303.7021, raising roughly $0.86 million. The sale, coded “S”, was solely to cover tax-withholding obligations triggered by restricted-stock-unit vesting and was not a discretionary trade.

After the transaction Chaudhry still beneficially owns approximately 26.9 million shares—353,565 held directly and the remainder through family trusts—leaving his overall stake virtually unchanged. No derivative securities were involved, and the filing does not disclose any changes to corporate strategy, governance or financial outlook. Accordingly, the Form 4 appears routine and immaterial to investors.
