ZS

Over the past six months, Zscaler's stock price has experienced significant volatility, decreasing by 27.89% over the last 12 months, with a year-to-date return of -6.52% as of September 22, 2026. A major event occurred on May 27, 2026, when shares dropped over 31% following a Q3 fiscal 2026 earnings report that, despite beating estimates, included cautious Q4 revenue guidance and news of senior sales executive departures, leading to securities fraud investigations. More recently, Zscaler reported strong Q4 and full-year fiscal 2026 results on September 3, 2026, exceeding Wall Street estimates with Q4 revenue up 25% to $898.2 million and adjusted EPS at $1.19, and annual recurring revenue (ARR) climbing 25% to $3.77 billion. This positive report, along with an upbeat fiscal 2027 outlook, caused ZS shares to increase by 15.69% in the past month as of September 22, 2026, though the company also announced a plan to reduce its workforce by about 3% to support AI initiatives.
