"SentinelOne reported Q3 FY2026 revenue of $258.91 million, up 22.9% year-over-year, beating the consensus estimate of $256.18 million. Non-GAAP EPS came in at $0.07 against an estimated loss of $0.175, a 140% beat. Furthermore, SentinelOne's non-GAAP operating margin hit a record 7%, representing roughly 1,200 basis points of improvement year-over-year."

"Yet, the market could end up pricing in tomorrow's disappointment instead of today's delivery. GAAP operating income remained deeply negative at -$73.31 million in Q3 FY2026, and the GAAP net loss was -$60.29 million. For investors who want a clean income statement, SentinelOne still can't offer one."

"SentinelOne's revenue growth has slowed from 29.5% in Q4 FY2025 to 22.9% in Q3 FY2026. That's still strong in absolute terms, but cybersecurity investors are accustomed to pricing in acceleration, not moderation. When the growth rate moves in the wrong direction, multiple compression follows."
