Zscaler’s Fourth Quarter Keeps the AI Faith: ARR Surges, Non-GAAP Margins Shine, and the Security Software Market Remains an AI Play

Ticker: ZS. EPS (non-GAAP) $1.19, EPS (GAAP) -$0.02, with earnings per share details nested in the company’s disclosures. The company’s revenue forecast visibility for the upcoming year remains awaited, as management emphasizes growth in ARR and platform adoption. In the near term, investors will be parsing how the results align with EPS consensus expectations and the sustainability of the 25% revenue growth pace.

Big numbers, big story

Zscaler reported a robust finish to fiscal Q4 and the fiscal year ended July 31, 2026. Revenue rose 25% year over year to $898.2 million, underscoring the company’s ongoing momentum in cloud security. Annual recurring revenue (ARR) climbed 25% to $3,771 million, with net new ARR totaling $246 million in the quarter. Stripping out the Red Canary acquisition, ARR still grew 20% year over year, with net new ARR up 17%—a reminder that the core platform thesis remains intact even as acquisitions flow into the model.

On the profitability side, GAAP operating loss was $15.5 million, or about 2% of revenue, while non-GAAP operating income reached $218.4 million, equating to 24% of revenue. In the bottom line, GAAP net loss was $3.4 million, but non-GAAP net income was $198.2 million, or about $1.19 per share on a diluted basis. The contrast between GAAP and non-GAAP tells a familiar story in software: stock-based comp, amortization, and related items are a stage backdrop that can mute headline profitability even as the underlying cash-generation engine hums.

Cash, capital, and the AI tailwinds

Cash provided by operations was $279.3 million, representing 31% of revenue, with free cash flow of $60.8 million (7% of revenue). The fourth quarter showed a capital expenditure and internal-use software outlay of $218.5 million, up sharply from $78.7 million in the prior-year period—suggesting stepped-up investment to fuel growth and AI-enabled capabilities within the platform.

Deferred revenue expanded 19% year over year, signaling durable revenue recognition and a backlog-like buffer to support subsequent quarters. The mix of cash generation, moderate GAAP losses, and strong non-GAAP profitability points to a business that is financing growth through operating cash flow rather than large new equity infusions.

Management view: AI as a growth engine, with security as a platform play

CEO Jay Chaudhry framed AI as a foundational opportunity for Zscaler’s platform—one that enables secure access to applications “without placing them on the network.” The company positions itself as a core enabler of Zero Trust SASE, Agentic SecOps, data security, and AI-security controls, with expectations that AI adoption will accelerate platform expansion and large-deal activity.

In CFO commentary, Kevin Rubin highlighted a growth engine broadening beyond traditional user-based licensing, aided by non-seat-based solutions and rising Z-Flex momentum. The narrative is less about a one-off AI booster and more about AI-enabled capabilities enhancing cross-sell and up-sell dynamics across the Zscaler platform.

What this could mean for the sector and peers

For peers in cloud security and AI-enabled security platforms, Zscaler’s Q4 results reinforce a few enduring themes: strong ARR resilience, the value of non-GAAP profitability in signaling scalable margins, and the importance of AI-driven product differentiation. If Zscaler’s AI investments translate into faster deployment cycles, better threat detection, and broader adoption across enterprise stacks, the competitive bar rises for others in SASE, Secure Access, and data security to demonstrate measurable efficiency gains and durable ARR growth.

However, the margin story remains nuanced. While non-GAAP profitability is solid, GAAP losses persist, reminding investors that the cost of growth—particularly in on-going AI and platform investments—continues to weigh on the headline bottom line. Sector peers may face similar trade-offs as they balance R&D tempo, acquisitions, and the need to maintain healthy cash conversion cycles.

Risks, leverage, and what to watch next

Key questions for investors and analysts include: How sustainable is the 25% revenue growth pace in a possibly moderating macro environment? Can non-GAAP margins hold steady as R&D and integration costs scale with AI initiatives? With the Red Canary acquisition now part of the mix, how much of ARR acceleration is driven by acquisitions versus organic expansion within existing customers? And, as always, how does the market price the company’s AI moat relative to peers?

Analysts and readers should watch for forward-looking measures such as revenue trajectory for fiscal year 2027, any updates to the revenue forecast, and how the company communicates its expectations around EPS consensus and cash-flow durability. The balance sheet, particularly free cash flow and the pace of capex, will also be a useful compass as AI-enabled security tools scale across multinational deployments.

Conclusion: AI-powered growth with a steady cash engine, but watch the horizon

Zscaler’s Q4 and FY2026 narrative is less about a single surprise and more about a durable, AI-augmented growth engine that is expanding beyond traditional user licensings into a broader, platform-driven model. ARR expansion, a healthy non-GAAP profitability framework, and cash generation paint a picture of a company that intends to compound momentum even as it reallocates dollars toward AI-enabled capabilities. For sector peers, that means a higher bar for market share gains and margin discipline—and a reminder that the AI wave in security is less a tide and more a carefully engineered tide pool with its own current dynamics.
