SentinelOne delivered robust top-line growth in QQ3 2025, underscored by a resilient ARR expansion and the rapid adoption of next-generation platform solutions. Revenue rose 28% YoY to $210.6 million, while total ARR reached $860 million, up 29% YoY, with net new ARR of $54 million (up 22% sequentially; up 4% YoY). The company achieved an 80% gross margin, and while GAAP operating margin remained negative at -5% (Driven in part by a few million dollars of one-time legal costs), management noted that ex one-time items the margin would be approximately -3%, in line with prior guidance. For the first time in trailing history, SentinelOne reported positive free cash flow on a trailing 12-month basis and maintained a strong liquidity position with over $1 billion in cash, cash equivalents and investments and no debt. Management raised full-year revenue guidance to approximately $818 million (+32% YoY) and provided Q4 revenue guidance of about $222 million (+27% YoY). Management emphasized expanding platform adoption (Purple AI, AI-SIEM), growing ARR per customer, and larger platform deals as the core drivers of sustainable growth, even as macro headwinds persist. The QQ3 performance reflects a combination of ongoing enterprise displacement from legacy incumbents, stronger demand for AI-powered autonomous security, and strategic partnerships (e.g., Lenovo, AWS, FedRAMP) that broaden market reach. This analysis synthesizes the financials with management commentary, assesses strategic positioning, benchmarks against peers, and provides an investment outlook with key risk factors.â ,
