Palo Alto Networks Q4 FY2026 Earnings: Revenue Growth Outpaces GAAP Profitability

Palo Alto Networks (NASDAQ: PANW) reported fiscal Q4 2026 revenue of $3.41 billion, up 34% from $2.54 billion, while GAAP diluted EPS swung to a $0.35 loss from earnings of $0.36 a year earlier. Next-Generation Security ARR rose 63% to $9.10 billion and cash generation improved, but faster cost growth and acquisition-related adjustments weighed heavily on GAAP profitability.

Core Financial Results

Subscription and support revenue provided most of the quarterly growth, helping total revenue increase by $874 million year over year. However, cost of revenue and operating expenses grew faster than revenue, reducing GAAP operating income by about 65%.

The adjusted results were substantially better: non-GAAP operating income rose 32% and non-GAAP diluted EPS increased about 7%. Adjusted free cash flow also grew 35%, with its margin remaining broadly stable.

Business and Platform Performance

Subscription and support revenue increased about 36% to $2.67 billion, compared with approximately 29% growth in product revenue to $738 million. Subscription and support contributed $710 million, or about 81%, of the company’s total year-over-year revenue increase.

Next-Generation Security ARR reached $9.10 billion, rising 63%, while remaining performance obligations increased 34% to $21.2 billion. Management said the quarter added nearly $1 billion of net new NGS ARR and attributed performance to Network & AI Security, Cortex, and Idira.

Palo Alto Networks also acquired Console, an AI-native platform for agentic workflows. The company expects Console to extend Cortex beyond security operations into broader enterprise agent-based workflows, although the release did not provide financial terms or quantify the expected contribution.

Cost Growth and Acquisition Charges Overwhelmed GAAP Revenue Growth

Total cost of revenue rose approximately 63% to $1.11 billion, materially faster than the 34% increase in revenue. Subscription and support cost increased from $543 million to $909 million, contributing to the decline in gross margin from about 73.2% to 67.6%.

Operating expenses increased approximately 57% to $2.13 billion. Research and development expense rose from $504 million to $779 million, sales and marketing increased from $829 million to $1.13 billion, and general and administrative expense climbed from $27 million to $226 million. As a result, GAAP operating margin fell by approximately 14.6 percentage points.

The difference between GAAP and non-GAAP operating income was $839 million. The reconciliation included $487 million of share-based compensation-related charges, $281 million of acquired intangible asset amortization, $68 million of acquisition-related costs, and $3 million of litigation-related charges. Acquisition-related costs included CyberArk integration expenses.

Below the operating line, Palo Alto Networks recorded $441 million of net other expense, compared with $95 million of net other income in the prior-year quarter. The non-GAAP reconciliation excluded a $524 million change in the fair value of convertible senior notes and capped calls, helping explain why GAAP results showed a net loss while non-GAAP net income reached $853 million.

Cash Flow and Balance Sheet

Cash generation remained positive despite the GAAP loss. Adjusted free cash flow increased to $1.29 billion, and its 37.8% margin was close to the prior-year level of 37.6%. For the full fiscal year, adjusted free cash flow margin was 38.4%.

Cash and cash equivalents totaled $2.51 billion at July 31, 2026, with another $557 million in short-term investments. Acquisition activity materially changed the balance sheet: goodwill increased to $22.01 billion from $4.57 billion, intangible assets rose to $7.02 billion from $763 million, and the company reported $1.77 billion of long-term convertible senior notes.

Financial Guidance

For fiscal Q1 2027, Palo Alto Networks expects revenue and NGS ARR to retain high year-over-year growth rates. The full-year outlook calls for 23% to 24% revenue growth, a 29.5% non-GAAP operating margin, and a 38.0% adjusted free cash flow margin, slightly below the 38.4% achieved in fiscal 2026.

The guidance uses non-GAAP measures that exclude share-based compensation, acquisition-related expenses, acquired intangible amortization, and other specified items. The company did not provide corresponding GAAP guidance.

Management’s View

CEO Nikesh Arora said advances in AI are raising cybersecurity’s priority among chief information officers and reiterated the company’s target of $20 billion in NGS ARR by fiscal 2030. CFO Dipak Golechha pointed to performance across the company’s three main platforms and maintained the longer-term goal of a 40% adjusted free cash flow margin in fiscal 2028.

Recent Insider Transactions

The provided insider data shows 94,478 shares purchased in three transactions and 156,879 shares sold in 18 transactions over the latest six-month period. That produced net sales of 62,401 shares, equal to a reported 1.0% reduction relative to total insider holdings of 6.19 million shares. The latest 10 reported transactions were all sales; this fact alone does not establish insiders’ views on the company’s outlook.

Risks Investors Should Monitor

• Persistent GAAP profitability pressure: Cost of revenue and operating expenses grew faster than sales in Q4, driving substantial gross- and operating-margin contraction.
• A wide GAAP/non-GAAP gap: Share-based compensation, acquired intangible amortization, acquisition expenses, and convertible-note fair-value changes created a large difference between reported and adjusted earnings. Some excluded items, including share-based compensation, are recurring.
• Acquisition and integration exposure: The sharp increases in goodwill and intangible assets demonstrate the balance sheet impact of acquisitions. Integration costs and future acquisition-related expenses could continue affecting GAAP results.
• Growth-rate normalization: Fiscal 2027 guidance implies 22% to 23% NGS ARR growth and 19% to 20% RPO growth, below the year-over-year rates reported for Q4 and projected for Q1. Execution against the full-year targets will therefore be an important indicator.
• Cash-flow margin execution and dilution: The fiscal 2027 adjusted free cash flow margin guide of 38.0% remains below management’s 40% fiscal 2028 target. GAAP diluted weighted-average shares also increased to 817 million from 709 million in the quarter.

Summary

Palo Alto Networks ended fiscal 2026 with 34% revenue growth, 63% NGS ARR growth, and higher operating and adjusted free cash flow. The main weakness was GAAP profitability, as cost growth, acquisition-related charges, intangible amortization, share-based compensation, and convertible-note valuation effects more than offset revenue gains. Fiscal 2027 guidance points to continued expansion, with investors needing to monitor margin stabilization, acquisition integration, growth-rate normalization, and progress toward the company’s longer-term cash-flow targets.
