Rubrik shares surge 11.05% after-hours on Q3 results exceeding guided metrics, 48% revenue growth, and raised full-year guidance.

Rubrik Inc. surged 11.05% in after-hours trading following the release of strong third-quarter fiscal 2026 financial results. The company reported 34% year-over-year growth in subscription ARR to $1.35 billion and 48% revenue growth to $350.2 million, both exceeding guided metrics. Management raised full-year revenue guidance to $1.28 billion from $1.23 billion, citing robust demand for its Security and AI Operations solutions. CEO Bipul Sinha highlighted record net new subscription ARR and free cash flow generation, while CFO Kiran Choudary noted $76 million in free cash flow. The results, coupled with upward guidance and analyst optimism (nine "Buy"/"Outperform" ratings), drove the post-market rally despite ongoing net losses.
