Zscaler Announces Strong Fourth Quarter and Fiscal 2026 Financial Results

Zscaler reported Q4 FY2026 revenue up 25% YoY to $898.2M and ARR up 25% YoY to $3.771B, with $246M net new ARR and non-GAAP operating margin rising to a record 24% (from 22%). Full-year FY2026 revenue grew 25% YoY to $3.353B and non-GAAP net income rose to $704.2M. For Q1 FY2027, management guided revenue to $935M–$939M (~19% YoY) and non-GAAP EPS to $1.15–$1.16; for FY2027, ARR is expected at $4.396B–$4.426B (~16.6%–17.4%). Overall momentum and margin expansion signal strong execution, likely supportive for Zscaler shares.

Analysis

The key mechanism here is not just durable growth, but a mix shift toward higher-value security workflows that reduces dependence on pure seat expansion. That is strategically positive for ZS and should pressure older perimeter/security stacks over time, but the forward guide implies the market is still underwriting an AI monetization story that has not yet translated into reacceleration. In the near term, this is more likely to be a multiple-maintenance event than a true upward reset unless the call shows net new ARR and large-deal conversion holding up ex-acquisition effects.

The bigger second-order issue is capital intensity disguised by non-GAAP optics. The jump in investment spending relative to revenue growth suggests FCF can stay noisy for several quarters, which matters because high-multiple software names trade on conversion, not just ARR. If growth slows into the high-teens while cash conversion remains suppressed, ZS can still execute operationally and underperform on valuation as investors rotate toward names with cleaner FCF leverage.

Consensus is probably missing that AI security is a very good narrative but a lagging P&L driver. The evidence of demand is real, yet the next leg of stock performance likely requires either a faster-than-guided ARR inflection or evidence that AI-related modules expand deal size without heavier implementation/capex burden. Falsifier: if the next quarter reaccelerates ex-Red Canary and FCF margin snaps back above ~20%, the market can re-rate the name quickly; if not, the growth premium should compress over 1-3 months.

Key Decisions for Investors

• Buy ZS on any post-earnings pullback only if the stock sells off >7% on guidance-related concerns; target a 1-3 month mean reversion trade into the call digest cycle. Risk/reward favors upside if the market overweights deceleration and ignores 24% operating margin expansion.
• Avoid chasing the open; wait for confirmation that net new ARR and large-deal commentary support the FY27 guide. If those metrics disappoint, treat it as a sell-the-rip setup rather than a momentum long.
• Pair trade: long ZS / short FTNT for 1-3 months. ZS has the cleaner cloud-native AI-security narrative and better operating leverage; FTNT is more exposed if buyers continue shifting budget away from appliance-led refresh cycles. Cover if FTNT reaccelerates bookings or ZS FCF stays sub-15%.
• Use a tactical options expression only if implied vol spikes: sell 1-2 month put spreads on ZS 8-10% below spot, betting that strong margin optics cap downside even if the guide is not exciting. Exit if the stock breaks below the post-print low on heavy volume.
• Watch for any disclosure that AI/security add-ons are mostly bundled, not incremental. If that becomes clear, expect multiple compression across the zero-trust/cloud-security basket over 6-18 months.
