SentinelOne delivered a solid QQ1 2026 performance with 23% year-over-year revenue growth to $229 million and ARR reaching $948 million, marking continued platform-driven expansion across endpoint, cloud, and data. The company posted a gross margin of 79% and achieved a fourth consecutive quarter of positive net income, complemented by a record 20% free cash flow margin. Management highlighted a strategic shift from product-centric to platform-based GTM, the acceleration of AI-enabled offerings (Purple AI and AI SIEM), and stronger enterprise adoption, including FedRAMP High authorizations for Purple, CNAP, and hyperautomation. Despite a softer Q1 net new ARR due to macro volatility and elongated sales cycles, guidance for Q2 and full-year 2026 remains constructive: revenue of ~$242M in Q2 (22% growth) and $996M–$1.0B for the full year (22% growth), with gross margins around 79% and operating margins expanding to 3–4%. SentinelOne also announced a $200M open-ended share repurchase authorization, underscoring confidence in the long-term trajectory and balance-sheet strength. The narrative is one of AI-powered security platform leadership, healthy ARR expansion, improving profitability trajectory, and disciplined investments to sustain velocity in a large, resilient market.
