Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 23% year-over-year to $2.67 billion, driven by a 9% increase in the customer base and expansion of subscriptions within existing accounts.
- Profitability Trend: Net loss narrowed to $41.5 million from $57.7 million in the prior year. Non-GAAP income from operations improved to $580.1 million (22% margin) from $442.2 million (20% margin).
- Debt Structure: The company issued $1.725 billion in 0.0% Convertible Senior Notes due 2028 in July 2025. Concurrently, it fully repaid the $1.15 billion Convertible Senior Notes due 2025, settling the principal in cash and the premium via stock issuance.
- Operating Expenses: Research and Development expenses rose 35% to $672.5 million due to increased headcount and investments in AI capabilities. Sales and Marketing expenses increased 14% to $1.26 billion.
- Acquisitions: Completed acquisitions of Airgap Networks and Avalor Technologies in fiscal 2024, and Red Canary in August 2025 (subsequent event).
Guidance, Outlook, and Risks
- Outlook: Management expects to continue incurring net losses for the foreseeable future as it invests in sales, marketing, and R&D. The company anticipates revenue growth rates will decline as the revenue base expands.
- Strategic Focus: Continued investment in "Zero Trust + AI" convergence, including Security for AI and Agentic Operations. The company plans to transition from reporting "Calculated Billings" to "Annual Recurring Revenue" (ARR) as a key metric starting in fiscal 2026.
- Risks:
- Macroeconomic Conditions: Uncertainty may lead to elongated sales cycles and increased scrutiny on large expenditures by customers.
- Competition: Intense competition from legacy appliance vendors and cloud-native competitors with greater resources.
- Debt Servicing: Significant cash requirements to service the 2028 Notes, though the notes bear 0.0% interest.
- Regulatory: Evolving data privacy laws (e.g., GDPR) and AI regulations globally.
Investor Verification Checklist
- Deferred Revenue Quality: Verify the composition of the $2.47 billion deferred revenue balance to assess future revenue visibility.
- Debt Conversion Terms: Review the conversion triggers and settlement terms (cash vs. stock) for the $1.725 billion 2028 Convertible Notes to understand potential dilution.
- Stock-Based Compensation: Analyze the $661.4 million in stock-based compensation expense and its impact on future cash burn and dilution.
- Customer Concentration: Confirm that no single customer exceeds 10% of revenue, though the top five channel partners accounted for 28% of revenue.
- Acquisition Integration: Monitor the integration and financial impact of the Red Canary acquisition (closed August 2025) on future operating margins.
