SentinelOne, Inc. reported a revenue of $1,001.3 million for the fiscal year ending January 31, 2026, marking a 22% increase from $821.5 million in the previous fiscal year. Despite this growth, the company experienced a net loss of $450.7 million, which widened from a loss of $288.4 million in fiscal 2025. The increase in revenue was attributed to new customer acquisitions and expanded sales of additional licenses and platform solutions to existing customers. The company's annualized recurring revenue (ARR) also grew by 22% year-over-year, reaching $1,119.1 million, driven by both new customer additions and increased adoption of adjacent solutions by existing customers.
In terms of operational metrics, SentinelOne reported an increase in its customer base, with 1,667 customers generating ARR of $100,000 or more as of January 31, 2026, up from 1,411 the previous year. The company’s international revenue represented 39% of total revenue, reflecting its ongoing geographic expansion. The total employee headcount increased to over 2,900, indicating a commitment to scaling operations to support growth. The company also made significant investments in research and development, which rose to $323.9 million, up from $267.0 million in fiscal 2025, as it continues to enhance its AI-powered cybersecurity platform.
Strategically, SentinelOne completed two acquisitions in September 2025, acquiring Prompt Security, Inc. and Observo, Inc. for a total consideration of approximately $264 million. These acquisitions are expected to enhance the company's product offerings, particularly in the areas of AI security and data pipeline technology. The company has also implemented restructuring plans aimed at improving operational efficiencies and aligning its workforce with current business needs, which resulted in restructuring charges of $12.3 million during the fiscal year.
Looking ahead, SentinelOne anticipates continued investment in its platform and expansion into new markets, despite the challenges posed by global macroeconomic conditions, including inflation and geopolitical tensions. The company has acknowledged a decline in usage patterns from certain larger enterprise customers and longer sales cycles, which may impact future revenue growth. However, it remains focused on driving customer adoption and expanding its market presence, particularly in the U.S. federal government sector, where it is already a certified vendor under the Federal Risk and Authorization Management Program (FedRAMP).
In summary, while SentinelOne's financial performance shows significant revenue growth, the company continues to face challenges related to profitability and market conditions. Its strategic acquisitions and ongoing investments in technology and talent are aimed at positioning the company for long-term success in the competitive cybersecurity landscape.
