Zscaler Hosts 2026 Investor Day, Reaffirms First Quarter and Fiscal 2027 Guidance
Presentations reinforce Zscaler’s growth plans and its position as the cybersecurity platform for the AI era
SANTA CLARA, Calif. – October 6, 2026 – Zscaler, Inc. (Nasdaq: ZS), the cybersecurity platform for the AI era, is hosting its 2026 Investor Day today in New York City. In conjunction with its Investor Day, Zscaler reaffirmed its financial guidance for the first quarter and full fiscal year 2027.
“As AI forces every enterprise to rethink their approach to security, the value of our Zero Trust architecture is becoming increasingly clear,” said Jay Chaudhry, CEO, Chairman, and Founder of Zscaler. “The agentic AI era is quickly becoming the most significant opportunity in our company’s history. Our Zero Trust platform was purpose-built to solve the challenges customers face today – protecting against AI-driven threats, securing data everywhere, and enabling the secure deployment of AI – by hiding the attack surface and preventing lateral movement. Backed by a powerful customer growth flywheel, we have multiple growth engines that we believe will enable us to capitalize on AI tailwinds and drive Zscaler towards achieving our $10 billion ARR target.”
At its Investor Day, Zscaler executives will discuss the company’s strategy, platform innovation, go-to-market priorities, and long-term growth drivers. Featured Zscaler executives include:
•Jay Chaudhry, CEO, Chairman, and Founder
•Kevin Rubin, Chief Financial Officer
•Adam Geller, Chief Product Officer
•Ross Tackett, Chief Revenue Officer
•Dhawal Sharma, Executive Vice President, AI & Data Security
Reaffirms First Quarter and Full year Fiscal 2027 Guidance
Zscaler reaffirmed its first quarter and full year fiscal 2027 guidance, previously provided on Sept. 3, 2026. For the first quarter of fiscal 2027, the company expects:
•Revenue of $935 million to $939 million, approximately 19% year-over-year growth.
•Non-GAAP gross margin of approximately 80%
•Non-GAAP income from operations of $215 million to $217 million, approximately 25% to 26% year-over-year growth, representing a 23% operating margin.
•Non-GAAP net income per share of approximately $1.15 to $1.16, assuming approximately 170 million fully diluted shares outstanding and a non-GAAP tax rate of 21%
For the full year fiscal 2027, the company expects:
•ARR of $4.396 billion to $4.426 billion, growth of approximately 16.6% to 17.4%.
•Revenue of approximately $3.908 billion to $3.938 billion, growth of 16.6% to 17.5%.
•Non-GAAP gross margin of approximately 80%
•Non-GAAP income from operations of $924 million to $932 million, growth of approximately 21%.
•Non-GAAP net income per share of $4.86 to $4.90, assuming approximately 173 million fully diluted shares outstanding and a non-GAAP tax rate of 21%.
•Free cash flow margin of approximately 23.0 to 23.5%.
Guidance for non-GAAP income from operations and non-GAAP net income per share exclude, as applicable, stock-based compensation expense and related employer payroll taxes, amortization expense of acquired intangible assets and amortization of debt issuance costs. We have not reconciled our expectations of non-GAAP income from operations and non-GAAP net income per share to their most directly comparable GAAP measures because certain items are out of our control or cannot be reasonably predicted. For those reasons, we are also unable to address the probable significance of the unavailable information, the variability of which may have a significant impact on future results. Accordingly, a reconciliation for the guidance for non-GAAP income from operations and non-GAAP net income per share is not available without unreasonable effort.
Investor Day: How to Participate
