Zscaler Shares Fall as Weak Guidance Overshadows Q4 Earnings Beat

Zscaler Inc. (ZS) reported strong fourth-quarter earnings that surpassed analyst estimates, but its stock fell after the company issued a forecast for fiscal 2027 that points to a significant deceleration in growth. The guidance overshadowed the quarterly beat, sending shares down 4.25% to $170.25 in trading on September 4, 2026, according to the source material.

A Tale of Two Forecasts

For its fourth quarter of fiscal 2026, Zscaler posted robust results, signaling continued demand for its cybersecurity products. The company reported:

• Revenue: $898.2 million, a 25% year-over-year increase and above the expected $877.0 million.
• Adjusted EPS: $1.19, beating the consensus estimate of $1.09.
• Annual Recurring Revenue (ARR): Reached approximately $3.8 billion, up 25% year-over-year.

However, the company's outlook for fiscal 2027 weighed on investor sentiment. Zscaler guided for full-year revenue between $3.908 billion and $3.938 billion, which implies a growth rate of just 16.6% to 17.5%. This marks a notable slowdown from the 25% growth achieved in fiscal 2026.

Investor Focus Shifts to Execution and Cash Flow

While management affirmed that underlying demand for cybersecurity remains strong, the earnings report highlighted several areas investors are watching closely. The company is navigating a sales force transition, with management noting that leadership changes are expected to stabilize in the first half of the new fiscal year.

Concerns also emerged around free cash flow, which appeared weaker in the fourth quarter. Capital expenditures hit approximately $200 million, or 22% of revenue, as Zscaler invested in data-center equipment. While the full-year free cash flow margin was a healthy 23%, near-term cash conversion has become a key metric for observation.

Upcoming Catalysts

Investors are looking ahead to several key dates for more clarity on Zscaler's growth trajectory and strategic initiatives. The company's first Analyst Day in five years, scheduled for October 6, 2026, is expected to provide insights into its long-term AI security opportunity and sales strategy.

Other upcoming events include the launch of its Agentic SecOps platform on September 9, 2026, and its next earnings release, tentatively scheduled for December 1. The market will be focused on whether new product adoption and improved sales productivity can help the company outperform its conservative guidance.
