Zscaler Stock Posts 25% Revenue Growth and All-Time High Operating Margin in Q3 FY26
Zscaler, Inc. (ZS) is a cloud-native cybersecurity company that routes enterprise traffic through its Zero Trust Exchange platform, replacing traditional firewalls with identity-based, application-level access controls. Reporting Q3 FY26 results on May 26, 2026, Zscaler stock delivered $850.5 million in revenue, up 25% year-over-year, exceeding guidance and beating the Street estimate by $14.8 million.
CFO Kevin Rubin described the result plainly: “We delivered strong Q3 ’26 results, growing revenue 25% while investing with discipline.”
The quarter’s standout financial metric was non-GAAP operating margin reaching 23%, what Rubin called “an all-time high,” driven by leverage on sales and marketing.
The forward story centers on three platform vectors gaining traction simultaneously: AI Protect, which crossed $100 million in bookings over the trailing twelve months; data security, which surpassed $500 million in ARR with over 30% year-over-year growth; and Zero Trust Branch, whose ARR approximately tripled year-over-year.
The near-term overhang is real: two senior sales leaders departed after the quarter’s close, prompting management to take a “prudent approach” to fiscal 2027 guidance of 16% to 17% ARR growth, which landed short of analyst expectations and triggered the selloff that now defines the setup for Zscaler stock.
Zscaler Stock’s Gross Profit Compounds at 26% While GAAP Costs Signal Platform Investment
Zscaler stock’s gross profit reached $658 million in Q3 FY26, growing 26% year-over-year from $522 million, a rate that slightly outpaced revenue growth and held gross margins steady at 77% versus 77% in the year-ago quarter.
The gross margin line has held in a tight band across eight quarters, ranging from 76% to 78%, which reflects a cost-of-revenue structure built for scale: as Zscaler stock processes more transactions through its existing exchange infrastructure, incremental revenue flows through at high efficiency.
Total operating expenses grew to $690 million in Q3 FY26 from $547 million a year earlier, a 26% increase that mirrors revenue growth and explains the persistence of GAAP operating losses in the (3%) to (4%) range.
The tension in Zscaler stock’s income statement is not deterioration but deferred leverage, with SG&A of $450 million and R&D of $230 million in Q3 FY26 absorbing the cost of platform expansion into AI security, SecOps, and Zero Trust Everywhere, investments that have not yet compressed operating expenses as a percentage of revenue on a GAAP basis
What the GAAP statement shows clearly is a gross profit engine compounding at 26% per year with remarkably stable unit economics, funding a cost structure that management characterizes as moving toward discipline, evidenced by the all-time non-GAAP operating margin of 23% reported this quarter.
Zscaler Stock’s 77% Gross Margin Holds a Durable Lead Over Cloudflare Across Eight Quarters
Zscaler stock has maintained gross margins between 76% and 78% across every quarter from July 2024 through April 2026, closing Q3 FY26 at 77%, a figure that has been essentially unchanged for two years despite the company absorbing the cost of three acquisitions and a significant R&D ramp.
Palo Alto Networks (PANW) has consistently posted the highest gross margins in this peer group, running between 74% and 74% across the same period before compressing to 68% in the most recent quarter, a notable step-down that narrows the gap with Zscaler stock considerably.
Meanwhile, Cloudflare (NET) trails both peers throughout the full eight-quarter window, declining from 78% in July 2024 to 71% by April 2026, a six-point compression that contrasts with Zscaler stock’s flat-to-stable profile and reinforces the durability of its platform cost structure at scale.
Is Zscaler Stock Undervalued in 2026? TIKR’s $228 Mid-Case Model Says the Selloff Created an Entry
TIKR’s mid-case model prices Zscaler stock at approximately $228, representing around 81% total return from the current $126 price over roughly 4.1 years, or approximately 15% annualized.
If Zscaler stock executes on the mid-case trajectory, with revenue growing at roughly 17% annually and net income margins expanding toward 21%, the model implies a price of approximately $392 by 2030, a total return of around 211% and an IRR of roughly 15%.
If growth decelerates toward the bear case, with revenue compounding at approximately 16% and margins settling near 19%, the model implies a price of approximately $278, still representing meaningful upside from current levels at roughly 10% annualized.
If the agentic security opportunity accelerates adoption and revenue growth approaches 19% with margins near 22%, the bull case implies approximately $538, translating to roughly 20% annualized returns over the same period.
Is Zscaler stock a buy right now?
Zscaler stock trades near its 52-week low of $115 after a 30%-plus post-earnings selloff driven by fiscal 2027 guidance of 16% to 17% ARR growth and two senior sales leadership departures.
The TIKR mid-case model implies approximately $228, roughly 81% above the current $126 price, but that return depends on whether the sales transition proves transitory and whether the AI security pipeline converts at scale.
Investors weighing a buy decision should examine whether the gross profit compounding rate of 26% in Q3 FY26 holds as the platform expands into non-seat-based pricing.
What is Zscaler’s guidance for fiscal 2027?
Management provided an early look at fiscal 2027 during the Q3 FY26 earnings call, guiding for 16% to 17% ARR and revenue growth. CFO Kevin Rubin cited two contributing factors: the departure of two senior sales leaders under CRO Mike Rich, which prompted a cautious approach to near-term guidance, and uncertainty around the pace of uptake for the integrated SecOps product expected to launch in fiscal 2027.
Full-year fiscal 2026 guidance calls for revenue of approximately $3.33 billion, representing 25% year-over-year growth.
