Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 14% year-over-year (YoY) for both the quarter and the nine-month period. Product revenue grew 18% (Q3) and 14% (9M), while Service revenue grew 13% (Q3) and 14% (9M).
• Profitability: Net income decreased 12% in Q3 2025 compared to Q3 2024, primarily due to a significant one-time gain on bargain purchase ($106.3M) from the Lacework acquisition in Q3 2024 that was not repeated in the current period. Operating income increased 16% YoY in Q3.
• Margins: Gross margin decreased 1.7 percentage points in Q3 (80.8% vs 82.5%) due to reduced benefits from inventory reserve releases and increased cloud service costs. However, operating margin improved to 31.7% in Q3 due to operating leverage.
• Balance Sheet: Cash and cash equivalents decreased to $1.996B from $2.876B at year-end 2024, largely driven by $2.23B in share repurchases during the first nine months of 2025. Inventory increased to $426.6M from $315.5M.
• Acquisitions: In Q1 2025, Fortinet completed the acquisition of Linksys, resulting in a $39.9M gain on bargain purchase. Other acquisitions in 2024 included Lacework and Next DLP.

Guidance, Outlook, and Risks

• Outlook: Management expects product and service revenue to continue growing for the remainder of 2025. Operating margin is expected to be relatively consistent with 2024 levels. Capital expenditures for Q4 2025 are estimated between $60M and $110M.
• Tax Legislation: The "One Big Beautiful Bill Act" (H.R. 1) enacted in July 2025 is expected to reduce cash paid for income taxes by $100M-$150M in 2025 but may increase the GAAP effective tax rate by approximately one percentage point.
• Share Repurchases: The Board approved a $1.0B increase to the repurchase program in August 2025, extending the term to February 2027. Approximately $795.9M remains available for repurchases.
• Key Risks:
  • Supply Chain: Continued reliance on third-party manufacturers and limited sources for key components (e.g., ASICs) exposes the company to shortages and cost increases.
  • Geopolitics: Tensions between China and Taiwan, the war in Ukraine, and potential tariffs could disrupt manufacturing and trade.
  • Product Vulnerabilities: Recent critical vulnerabilities in FortiManager products pose reputational and operational risks.
  • Litigation: Two securities class action lawsuits were filed in September and October 2025 alleging false statements regarding the 2026 firewall refresh cycle.

Investor Verification Checklist

• Inventory Levels: Verify the rationale behind the 35% increase in inventory ($315.5M to $426.6M) and assess the risk of obsolescence or write-downs.
• Deferred Revenue: Confirm the $6.65B deferred revenue balance and its conversion rate to future revenue, noting the $3.49B expected recognition in the next 12 months.
• Share Repurchase Impact: Review the $2.23B spent on buybacks in the first nine months and its impact on liquidity relative to the $1.0B debt maturing in March 2026.
• Legal Proceedings: Monitor the status of the securities class action lawsuits filed in late 2025 regarding the 2026 firewall refresh cycle.
• Cloud Cost Structure: Analyze the impact of increased cloud service costs on service gross margins as the company expands data center footprint.
