Both cybersecurity firms beat fiscal second-quarter revenue and earnings estimates, yet Rubrik fell about 8% even after raising full-year guidance, while SentinelOne dropped on a soft annual profit forecast.
Rubrik Inc. and SentinelOne Inc. saw their shares decline in late trading on Aug. 27, 2026, even though both cybersecurity companies delivered fiscal second-quarter results that beat expectations on revenue and earnings. The paired sell-offs underscore how, for software vendors in the security and AI operations space, a strong quarter alone is no longer enough to satisfy a demanding market.
Rubrik bore the steeper reaction, with the stock dropping about 8% after hours. Notably, the decline came even as the security and AI operations company lifted its outlook for the full year — a step that would typically signal confidence in the demand environment. The negative response indicates the raised outlook fell short of what investors had anticipated.
SentinelOne, for its part, slid on its profit guidance. The company also topped estimates on both revenue and earnings for the fiscal second quarter, but a soft annual profit forecast proved to be the number that mattered, with the forward profitability picture outweighing the in-period beat. The stock's late-trading slide reflected that tension between a solid quarter and a guarded full-year profit view.
Taken together, the two moves point to a consistent dynamic for cybersecurity vendors reporting this cycle: guidance is the decisive variable. Rubrik's raised full-year outlook was not enough to prevent a drop of roughly 8%, while SentinelOne's cautious annual profit forecast turned a double beat into a decline. For both companies, the after-hours action served as a reminder that investors are judging these names on what comes next rather than on the quarter just reported.
