Zscaler Inc. reaffirmed its financial guidance for the first quarter and full fiscal year 2027 during its 2026 Investor Day held in New York City on October 6, 2026. The cybersecurity firm maintained its forecast for revenue growth and operating margins, signaling confidence in its Zero Trust architecture amidst the evolving AI landscape.

Guidance highlights

For the first quarter of fiscal 2027, Zscaler expects revenue between $935 million and $939 million, representing approximately 19% year-over-year growth. Non-GAAP income from operations is projected at $215 million to $217 million, implying a 23% operating margin. The company anticipates 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 reiterated its Annual Recurring Revenue (ARR) target of $4.396 billion to $4.426 billion, reflecting growth of approximately 16.6% to 17.4%. Total revenue is expected to range from $3.908 billion to $3.938 billion, marking growth of 16.6% to 17.5%. This revenue outlook exceeds the analyst estimate of $3.899 billion. Non-GAAP income from operations is expected to reach $924 million to $932 million, representing approximately 21% growth. The reaffirmed adjusted EPS guidance of $4.86 to $4.90 also surpasses the analyst consensus estimate of $4.60.

Strategic focus on AI security

Jay Chaudhry, CEO, Chairman, and Founder, emphasized that the agentic AI era represents the most significant opportunity in the company's history. He stated that the Zero Trust platform is designed to protect against AI-driven threats, secure data, and enable secure AI deployment by hiding the attack surface and preventing lateral movement. The company aims to leverage this positioning to drive towards its long-term $10 billion ARR target.

Executives including CFO Kevin Rubin, Chief Product Officer Adam Geller, and Chief Revenue Officer Ross Tackett discussed strategy, platform innovation, and go-to-market priorities. Dhawal Sharma, Executive Vice President, AI & Data Security, also participated in the discussions.

What the numbers show

The guidance reveals a divergence between top-line growth rates across periods. While Q1FY27 revenue growth is guided at approximately 19%, the full-year FY27 revenue growth is projected at 16.6% to 17.5%. This suggests that management expects revenue growth to moderate in the subsequent three quarters compared to the strong start anticipated in Q1. Additionally, the free cash flow margin guidance of 23.0% to 23.5% for FY27 aligns closely with the non-GAAP operating margin of roughly 23% implied in the Q1 guidance, indicating consistent cash conversion efficiency relative to operational profitability throughout the fiscal year. Notably, both the revenue outlook ($3.908B-$3.938B vs $3.899B est.) and adjusted EPS guidance ($4.86-$4.90 vs $4.60 est.) exceed analyst expectations, signaling confidence in operational execution despite the projected moderation in quarterly growth rates.

Zscaler (NASDAQ: ZS) announced the appointment of Ross Tackett as its Chief Revenue Officer, effective October 1, 2026. Tackett will lead the company’s global revenue operations, sales organization, strategic partner ecosystem, and go-to-market execution.

Tackett previously served as Zscaler’s Head of Worldwide Sales and has been with the company for three years. He brings more than three decades of technology sales leadership experience, including over a decade at ServiceNow and more than 16 years at Dell. His tenure has focused on scaling multi-billion-dollar enterprise go-to-market organizations and accelerating international expansion.

Leadership transition details

Tackett succeeds Mike Rich, who is stepping down as CRO for personal reasons. Rich will remain with Zscaler as a strategic advisor through December 31, 2026, to ensure a seamless transition. Jay Chaudhry, CEO, Chairman, and Founder of Zscaler, highlighted Tackett’s operational discipline and global scale as key factors in the selection.

Strategic focus

The leadership change occurs as enterprises increasingly retire legacy firewall and VPN-based security in favor of Zero Trust architecture. Tackett stated that Zscaler is positioned as the platform of choice for this shift, aiming to scale the global commercial engine and deliver transformative business outcomes for customers.

Chaudhry emphasized that Tackett’s deep domain expertise and international experience make him ideal to guide the global sales organization amid urgent infrastructure modernization needs. Rich expressed pride in the milestones achieved by the global team and confidence in Tackett’s ability to sustain momentum.
