Key Financial Metrics

Material Changes vs. Prior Period

• Expense Management: Total operating expenses remained flat year-over-year in Q3 ($121.1 million vs $115.3 million) despite a 30% increase in R&D spend. Restructuring charges of $9.7 million incurred in Q3 2024 were absent in 2025.
• Interest Expense: Interest expense surged 568% in Q3 2025 ($3.2 million vs $0.5 million) primarily due to coupon interest on the 7.75% Convertible Senior Notes due 2028 issued in late 2024.

Guidance, Outlook, and Risks

• Outlook: Management expects to continue incurring operating losses in the foreseeable future due to investments in sales, marketing, and platform infrastructure. The company anticipates gross margins to increase over the long term as revenue growth outpaces cost increases.
• Debt Maturity: Approximately $188.6 million of 0% Convertible Senior Notes due 2026 matures on March 15, 2026. The company has $150.0 million of 7.75% Convertible Senior Notes due 2028.
• Material Weakness: The company identified a material weakness in internal control over financial reporting related to the revenue process, citing a lack of qualified personnel and insufficient monitoring of third-party billing systems. Remediation efforts are underway.
• Legal Proceedings: The company is a defendant in a securities class action lawsuit (filed May 2024) and multiple stockholder derivative actions. The court granted in part and denied in part the motion to dismiss the class action in September 2025; a second amended complaint was filed in October 2025.
• Customer Concentration: The top 10 customers generated 32% of revenue in the trailing 12 months. TikTok remains a significant customer, though potential U.S. legislative bans pose a risk to future traffic levels.

Investor Verification Checklist

• Debt Repayment Capacity: Verify the company's ability to repay or refinance the $188.6 million of 2026 Notes maturing in March 2026, given the current cash balance of $113.1 million and ongoing operating losses.
• Internal Control Remediation: Monitor progress on remediation of the material weakness in revenue recognition controls to ensure future financial reporting reliability.
• TikTok Exposure: Assess the potential impact of U.S. legislation regarding TikTok on Fastly's revenue, given the customer's significant contribution to traffic.
• Operating Leverage: Evaluate whether the 30% increase in R&D expenses will translate into sustainable revenue growth and margin expansion in future quarters.
• Litigation Costs: Track the status of the securities class action and derivative lawsuits for potential settlement costs or reputational damage.
