Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 30% year-over-year, driven by a 40% increase in new paying customers and a dollar-based net retention rate of 120%.
- Cost Structure: Cost of revenue rose 46% due to increased third-party technology services, co-location/bandwidth costs, and depreciation from server acquisitions. This contributed to a gross margin compression from 77% to 75%.
- Operating Expenses: Total operating expenses increased 26% to $1.82 billion. Sales and marketing expenses rose 23% (driven by a 25% headcount increase), and R&D expenses rose 22% (driven by a 22% headcount increase).
- Liquidity Position: Cash and cash equivalents surged from $147.7 million to $943.5 million, bolstered by $2.0 billion in proceeds from the issuance of 2030 Convertible Senior Notes and $309.6 million from the settlement of 2025 capped call transactions.
- Customer Base: Total paying customers grew to 332,466 (up from 237,714). Large customers (>$100k annualized revenue) increased to 4,298 (up from 3,497).
Guidance, Outlook, and Risks
Management Commentary & Outlook: Management expects to continue incurring operating losses and cash flow fluctuations in the foreseeable future due to strategic investments in infrastructure, R&D, and sales expansion. The company anticipates macroeconomic uncertainty to persist through 2026, potentially leading to lengthened sales cycles and customer churn. Cloudflare intends to reinvest cash flow into business expansion rather than maximizing short-term profitability.
Key Risks & Contingencies:
- Profitability: The company has a history of net losses and an accumulated deficit of $1.2 billion; future profitability is not guaranteed.
- Geopolitical & Macroeconomic: Tariffs, trade restrictions, and global conflicts could increase equipment costs and reduce customer spending. International revenue accounted for 51% of total revenue in 2025.
- Network Reliability: The company experienced widespread service unavailability in November and December 2025 due to software update deployments. Core co-location facilities in Portland, Oregon, and Amsterdam are critical single points of failure.
- Regulatory & Legal: Exposure to evolving data privacy laws (GDPR, EU AI Act), export controls, and potential liability from customer content. An Italian regulator issued a €14.2 million fine in December 2025, which Cloudflare is challenging.
- Debt Obligations: Significant debt service requirements exist for the 2026 and 2030 Convertible Notes. The 2026 Notes are classified as current liabilities due to the if-converted value exceeding principal.
Investor Verification Checklist
- Debt Maturity Profile: Verify the ability to service or refinance the $1.29 billion in 2026 Notes maturing in August 2026, which are currently classified as current liabilities.
- Network Outage Impact: Assess the financial and reputational impact of the November/December 2025 service outages and any resulting service credits or customer attrition.
- Regulatory Fines: Monitor the status of the €14.2 million fine from Italian regulators and potential exposure under the EU AI Act and Digital Services Act.
- Capital Expenditure Efficiency: Review the correlation between the 71% increase in capital expenditures (including server acquisitions) and the resulting revenue growth to ensure margin expansion is sustainable.
- Large Customer Concentration: While no single customer exceeds 10% of revenue, verify the stability of the top-tier large customer base (4,298 customers) given the lengthening sales cycles mentioned in the risk factors.
