SentinelOne, Inc. (NYSE: S) reported Q3 fiscal 2026 earnings on Dec. 4, 2025, showing rising revenue, annual recurring revenue (ARR), and positive non-GAAP earnings per share (EPS). Shares fell about 11% after management lowered near-term revenue guidance and disclosed CFO Barbara Larson’s planned resignation.

Quarter Results and Profitability

SentinelOne posted Q3 revenue of about $259 million, up roughly 23% year over year. ARR reached approximately $1.055 billion, also up about 23%. Non-GAAP EPS was $0.07, a positive result compared with break-even a year earlier and above consensus estimates. The company described the quarter as a key step toward sustainable profitability, highlighting improved non-GAAP operating margins and positive net income. Its earnings materials emphasized growing demand for its AI-native Singularity platform and the integration of recent cloud-security capabilities as drivers of medium-term growth.

Guidance, Backlog, Valuation, and Leadership Changes

Management guided Q4 revenue to about $271 million, implying roughly 20% year-over-year growth but modestly below analyst expectations. Fiscal 2026 revenue is forecast at around $1.0 billion, slightly under consensus but still reflecting double-digit growth. Buy-side commentary noted backlog growth of about 34% year over year to roughly $1.3 billion and stabilizing net new ARR. At least one analyst upgraded the shares to Buy and raised the price target, citing a valuation near four times forward enterprise value to revenue and mid-teens percentage upside from depressed levels.

Shares declined about 11% following the softer near-term outlook and the CFO departure announcement. The company disclosed in a Form 8-K that CFO Barbara Larson notified the board on Dec. 1, 2025, of her intention to resign around mid-January 2026. The filing stated her exit was not due to any disagreement with the company’s operations, policies, or practices. Chief Growth Officer Barry Padgett will serve as interim CFO and principal financial officer while a permanent successor is sought. The filing also recorded the board’s appointment of former OpenText CEO and CTO Mark Barrenechea as a Class II director with standard outside-director compensation.

The timing of the CFO transition will be closely watched as management aims to sustain margin gains while converting backlog and ARR improvements into renewed revenue growth. Analysts view the lowered guidance as a reset of expectations, supported by strong backlog and ARR trends that could enable gradual re-acceleration beyond near-term headwinds.
