Filed October 30, 2025For Securities:NET

Summary

Cloudflare, Inc. (NET) reported its financial results for the quarter ending September 29, 2025. The company demonstrated continued strong revenue growth, with a 31% increase year-over-year for the three-month period and a 28% increase for the nine-month period. This growth was primarily driven by an expansion in paying customers and strong retention rates, as indicated by a dollar-based net retention rate of 119% for the quarter. Despite the revenue growth, Cloudflare reported a net loss for both the three-month and nine-month periods. The cost of revenue increased significantly, impacting gross margins, which decreased from 78% to 74% year-over-year for the quarter. Operating expenses also saw increases across sales and marketing, research and development, and general and administrative functions, largely due to increased headcount and stock-based compensation. The company also significantly increased its cash and cash equivalents and available-for-sale securities, bolstered by proceeds from its 2030 convertible senior notes issuance. While the company remains net-loss generating, its strong revenue growth, increasing customer base, and substantial cash reserves position it for continued investment and expansion.
