SentinelOne, Inc. reported third-quarter results showing continued growth but ongoing losses. Revenue for the three months ended October 31, 2025 rose to $258.9 million, up 23% from $210.6 million a year earlier, driven by both U.S. and international demand for its AI-powered cybersecurity platform. Gross profit increased to $191.1 million, but operating expenses of $264.4 million, including higher research and development and restructuring costs, led to an operating loss of $73.3 million and a net loss of $60.3 million, or $0.18 per share.
