Zscaler (ZS) Q2 2026 earnings review
Accelerating Revenue and Raised Guidance, Boosted by M&A
Zscaler delivered a strong beat-and-raise quarter, with Q2 revenue accelerating to 26% YoY to reach $815.8 million, easily exceeding the high end of previous guidance. The company raised its full-year FY26 top-line and profitability outlook across the board, bumping ARR growth to 24% and Non-GAAP EPS to $3.99-$4.02. Profitability remained excellent on a non-GAAP basis, maintaining a 22% operating margin, enabling the company to operate at an elite 'Rule-of-62' fiscal year-to-date. However, GAAP net loss widened to $34.3M, pressured by stock-based compensation and acquisition-related expenses.
🐂 Bull Case
The combination of 26% top-line growth and impressive cash flow generation demonstrates exceptional operating leverage. Zscaler successfully balances aggressive expansion and M&A integration with high-tier non-GAAP profitability.
Management confidently raised full-year FY26 expectations for Revenue, ARR, Operating Income, and EPS, signaling high visibility and robust demand for its broader platform.
🐻 Bear Case
While total ARR grew 25%, excluding Red Canary's $114.0 million contribution, organic ARR growth was 21%. This represents a slight deceleration compared to historical mid-20s organic growth rates.
GAAP net losses widened significantly to $34.3 million (from $7.7 million a year ago) due largely to $220.4 million in stock-based compensation, which now consumes 27% of total quarterly revenue.
⚖️ Verdict: 🟢
Bullish. The headline numbers are spectacular and the raised guidance points to sustained momentum. While the M&A contribution is doing some heavy lifting for the growth metrics and SBC remains high, Zscaler's strategic positioning and cash generation are undeniable.
Key Themes
AI Security Surging Through Innovation and M&A
Zscaler is aggressively positioning itself as 'the cybersecurity platform for the AI age'. With a 91% YoY surge in enterprise AI usage and a 93% increase in data transfers to AI/ML applications, demand is accelerating. The company recently announced 'Zscaler AI Protect' to provide end-to-end governance and acquired SquareX to secure unmanaged devices and standard browsers against AI-era threats.
Platform Consolidation via Z Flex
Customers continue to consolidate point products onto Zscaler's Zero Trust Everywhere and Data Security pillars. The Z Flex go-to-market program, which allows customers to commit spend with module-swapping flexibility, is removing friction from procurement and driving larger, multi-year strategic commitments.
Deepening Ecosystem Integrations
Zscaler is leveraging massive distribution channels. Earning the AWS Marketplace Partner of the Year award highlights significant cloud channel momentum, and its early adoption partnership for the Microsoft Entra Agent ID ecosystem embeds Zscaler directly into non-human AI agent identity management.
Growth Heavily Supplemented by Acquisitions
A specific data point contradicts the purely organic acceleration narrative: Q2 ARR grew an impressive 25% YoY to $3.359 billion, but excluding Red Canary's $114.0 million ARR, the organic ARR grew 21%. Furthermore, organic net new ARR grew only 7% YoY, indicating that the core business growth is decelerating slightly as it scales.
Widening GAAP Losses Despite Scale
Despite a massive $815.8M revenue quarter, GAAP loss from operations worsened to $51.8 million (6% of revenue) from $40.1 million a year ago. This is directly attributable to stock-based compensation and related payroll taxes, which jumped from $176.4M in 25Q2 to $220.4M in 26Q2. M&A-related amortization also increased sharply.
Macro Scrutiny on Large Deals Persists
While management did not cite direct macro deterioration in the earnings release, earlier quarters established that IT budgets remain tight and large multi-pillar transformations require significant C-level scrutiny. Execution relies heavily on demonstrating cost-takeouts of legacy firewalls and VPNs.
Other KPIs
Stable. Free cash flow represented a 21% margin, up slightly in absolute dollar terms from $143.4M (22% margin) a year ago. It marks a normalization from Q1's massive 52% FCF margin, but validates the company's ability to reliably generate cash while absorbing the Red Canary and SPLX acquisitions.
Accelerating. Deferred revenue grew 25% YoY, matching the headline ARR growth. This strong forward-looking metric validates robust bookings and expanding multi-year platform commitments from enterprise clients.
Guidance
Accelerating. Raised from the previous guide of $3.282B - $3.301B. The new midpoint implies 24% YoY growth, effectively sustaining the hyper-growth trajectory driven by platform expansion and the inclusion of Red Canary.
Accelerating. Upgraded from $3.698B - $3.718B, representing 24% growth. This is the company's primary north-star metric and the raise demonstrates strong pipeline conversion expectations.
Accelerating. Meaningfully raised from previous guidance of $3.78 to $3.82. This represents 22-23% YoY growth and reflects strong top-line flow-through, aided by a newly adopted long-term 21% non-GAAP tax rate.
Stable. Represents ~23% YoY growth, a slight deceleration from Q2's 26% growth rate, but squarely in line with the broader full-year targets.
Key Questions
Pacing of Organic ARR Growth
Organic net new ARR grew 7% this quarter excluding Red Canary. As the denominator grows, what is the expected long-term sustainable growth rate for the core, organic business?
Stock-Based Compensation Trajectory
SBC reached over 27% of revenue this quarter, driving GAAP losses wider despite excellent non-GAAP margins. When does management expect SBC as a percentage of revenue to begin meaningfully tapering?
SquareX Integration & Monetization
With the recent acquisition of SquareX for browser security, will this be packaged as an upsell module within Zero Trust Everywhere, or integrated as a core feature to drive new logo land-and-expand?
AI Platform Gross Margins
Management previously noted that new products are initially optimized for GTM speed over margins. How is the aggressive rollout of AI Protect and Red Canary impacting the underlying gross margin structure?
