Zscaler posted Q4 FY2026 revenue of $719.2 million, up 21% year-over-year, and lifted full-year FY2027 growth guidance to 24.7%, decisively reversing the cautious trajectory that triggered a 31.5% single-session collapse in May.
- Q4 revenue of $719.2 million rose 21% year-over-year; remaining performance obligations surged 30% to $6.5 billion, signaling durable forward demand.
- Full-year FY2027 revenue guidance of $3.3295 billion to $3.3325 billion implies 24.7% growth - a sharp pivot from the 16-17% outlook that blindsided investors on May 27.
- Annual recurring revenue crossed $3 billion for the first time, alongside record operating margins, as CEO Jay Chaudhry flagged AI Guard and GenAI security as emerging enterprise priorities.
Lead
Zscaler (ZS) reported fiscal fourth-quarter results after the market close on Wednesday, September 3, delivering revenue of $719.2 million and a new full-year FY2027 outlook that resets the growth narrative after one of cybersecurity's worst single-day reactions in recent memory. The San Jose-based cloud security provider posted a 21% revenue gain for the quarter and guided first-quarter FY2027 revenue to $875 million to $878 million, essentially matching analyst consensus of $877.1 million. The larger signal came from the full-year FY2027 forecast: $3.3295 billion to $3.3325 billion, pointing to 24.7% growth - nearly 800 basis points above the 16-17% range that ignited the May sell-off.What Did Zscaler Report This Quarter?
Zscaler's Q4 metrics painted a picture of reaccelerating demand. Remaining performance obligations - a leading indicator of future revenue - rose 30% year-over-year to $6.5 billion, while deferred revenue climbed 25% to $2.48 billion. Annual recurring revenue surpassed $3 billion for the first time in the company's history, accompanied by record non-GAAP operating margins. Non-GAAP earnings per share came in at $0.89 for the quarter, against a consensus estimate of $1.09, as the company continued to invest ahead of the AI security cycle. Full-year FY2027 non-GAAP EPS guidance of $4.10 to $4.11 and free cash flow margins of 22.8% to 23.3% frame a profitable growth trajectory despite those front-loaded investments.
Why Did May's Crash Define This Print?
The May 27 session - when ZS stock collapsed 31.5% in a single day - became the defining psychological event for the stock heading into this report. Management's pairing of a quarterly beat with a deceleration signal to 16-17% annual growth unnerved institutional holders who had priced ZS for sustained 25%-plus expansion. The FY2027 guidance issued Wednesday undoes that deceleration narrative directly, restoring the growth rate to a level broadly consistent with pre-correction expectations. The severity of the prior sell-off had conditioned investors to treat even in-line results with suspicion; the guidance step-up changes the calculus materially.
How Does AI Security Demand Shift the Competitive Picture?
Zscaler's positioning within the broader ai stocks trade hinges on its ability to monetize a new attack surface: AI agents. CEO Jay Chaudhry described a world of "billions of agents" that require the same zero-trust inspection applied to human users, and noted significant customer interest in AI Guard and GenAI security offerings. The company now secures nearly 40% of the Global 2000 and 45% of the Fortune 500. Chaudhry was explicit that AI security was not yet factored into Q4 financials but expected to carry "meaningful impact" in fiscal 2027 - a forward statement that aligns with signals from rivals. CrowdStrike (CRWD) just delivered what it called its best quarter ever, posting 26% revenue growth and record net new ARR of $333 million - up 51% year-over-year - and raised its FY2027 net new ARR guidance by 630 basis points to 34%. Palo Alto Networks (PANW) beat estimates for a sixth consecutive quarter while holding more than 2,000 customer AI security briefings. Together, those prints validated that enterprise buyers are accelerating security spending to defend AI infrastructure, not deferring it.Market Reaction and Investor Positioning
ZS shares had already partially recovered heading into the print, rallying 9.98% to $187.30 on August 27 after JPMorgan raised its price target to $215 with an Overweight rating. The aftermarket reaction to Wednesday's results will determine whether that pre-positioning holds or extends. Analysts entered the session divided: the revenue trajectory and RPO growth supported a constructive thesis, while EPS softness and lingering guidance credibility concerns kept sentiment measured. The FY2027 outlook, at 24.7% topline growth, is the figure most likely to resolve that divide in the near term.
Outlook
Zscaler's Q4 FY2026 report delivers on the two most consequential variables investors demanded: a revenue trajectory that holds above 20% and a full-year outlook that removes the deceleration stigma of May. The $6.5 billion RPO provides a tangible forward revenue floor, and management's explicit signaling on AI security monetization in fiscal 2027 positions ZS as a primary beneficiary of the enterprise AI buildout. The quarter does not resolve every risk - margin trajectory and the pace of AI product adoption remain open questions - but the guidance upgrade is the material development the market had been waiting for since May 27.
