Zscaler (ZS) delivered a very strong 1Q26 print on almost every operating metric, but a conservative ARR outlook for the remainder of FY26 is overshadowing the upside and driving the sharp post-earnings sell-off. The tension between robust demand across its three growth pillars and a modestly higher full-year ARR guide is the central issue for the stock near term.

• Q1 revenue rose 25.5% yr/yr to $788.1 mln, and ARR increased 26% to $3.204 bln, both ahead of expectations, while non-GAAP EPS also comfortably topped consensus.
• RPO growth accelerated to 35% yr/yr to $5.9 bbln (from 31% last quarter) and cRPO grew 29%, underscoring strong demand and visibility despite a still-tight IT spending backdrop.
• Profitability remains a key differentiator. ZS operated at “Rule-of-78,” with 26% revenue growth and a 52% free cash flow margin, alongside 22% non-GAAP operating margin.
• The issue for the stock is guidance. FY26 ARR is now projected at $3.698-$3.718 bln (22.7–23.3% growth), only slightly above prior guidance and by less than the amount by which Q1 ARR exceeded forecasts at the midpoint.
• This implies management effectively used most of the Q1 ARR beat to de-risk the year, rather than re-basing expectations higher, which investors interpret as a sign of caution for the remaining three quarters.
• Importantly, the cautious ARR posture comes even as AI Security ARR has already exceeded the prior $400 mln FY26 target three quarters early and is now expected to surpass $500 mln by year-end.
• Data Security Everywhere ARR has accelerated to about $450 mln, and Zero Trust Everywhere has more than 450 enterprises, hitting its FY26 goal early and driving incremental demand for AI and data security.
• The Z-Flex commit-to-spend model (over $175 mln in Q1 TCV, up 70% qtr/qtr) is proving to be a powerful upsell and consolidation lever, pushing larger, multi-module platform deals.
• The Red Canary and SPLX acquisitions slightly exceeded internal expectations but remain immaterial to near-term revenue, serving instead as key strategic pieces that deepen ZS’s AI-powered SecOps and AI Security platforms.

Briefing.com Analyst Insight:

ZS’s quarter was fundamentally very strong, with accelerating RPO, robust growth across AI Security, Data Security Everywhere, and Zero Trust Everywhere, and elite free cash flow margins for a company at this scale. However, the modest step-up in FY26 ARR guidance - smaller than the Q1 ARR beat - introduces an asterisk to the print and explains the sharp share-price reaction, as a premium-multiple story is now paired with a more conservative growth outlook for the balance of the year. The key debate is whether this caution proves to be disciplined “under-promise and over-deliver” guidance or an early signal that sustaining mid-20s ARR growth will be incrementally tougher even with a powerful AI and Zero Trust product cycle underway.
