This performance has sparked investor optimism, reflecting confidence in Rubrik's strategic positioning and future prospects.

Key Financial Highlights

Rubrik reported a GAAP net loss per share of $(0.61) for the fourth quarter, significantly better than the analyst consensus estimate of $(0.80).

Factors Contributing to Narrower Loss

Several factors contributed to Rubrik's narrower-than-expected loss:

1. Improvement in Operating Leverage: Rubrik's Subscription ARR Contribution Margin improved from -12% in the fourth quarter of fiscal 2024 to 2% in the fourth quarter of fiscal 2025. This significant improvement reflects better operational efficiency and cost management.

2. Positive Free Cash Flow: Rubrik achieved positive free cash flow of $75.2 million in Q4 2025, compared to $8.7 million in the same period the previous year. This transition to positive cash flow indicates financial maturity and better cash management.

3. Revenue Growth: Rubrik's total revenue grew by 47% year-over-year to $258.1 million in Q4 2025. This substantial revenue growth helps in offsetting costs and losses, contributing to a narrower loss.

4. Customer Growth: Rubrik added 2,246 customers with $100K or more in Subscription ARR, up 29% year-over-year. This growth in high-value customers indicates strong market demand and validates Rubrik's strategic positioning in the cybersecurity market.
