Rubrik (NYSE: RBRK) delivered a clean beat. Revenue of $387.1 million topped the $366.3 million consensus by nearly 6%. Non-GAAP diluted EPS of $0.16 swung from a $(0.15) loss a year ago and crushed the $(0.03) analyst estimate. Management then raised every guided metric for the full fiscal year, including revenue to $1.638B–$1.648B and non-GAAP EPS to $0.25–$0.35.
The headline numbers are solid, but the composition matters more. Subscription revenue grew 41% year-over-year to $374.2 million, accounting for 97% of total revenue. Excluding $8.5 million in material rights revenue, subscription revenue grew 43% — accelerating from the prior year's 40% growth on the same basis. Subscription ARR reached $1.57 billion, up 32% YoY, with net new ARR driving a 13.2% contribution margin versus 8.0% a year ago. That 520-basis-point improvement in ARR contribution margin is the clearest signal that Rubrik is converting its growing customer base into higher-margin recurring revenue without proportionally increasing its cost base.
Gross margins expanded too. GAAP gross margin hit 80.5%, up from 78.3%, while non-GAAP gross margin reached 82.9% versus 80.5%. The expansion came from subscription scale rather than price increases — subscription cost of revenue grew 29% YoY while subscription revenue grew 41%, a textbook operating leverage story. Free cash flow margin improved to 19% from 12%, generating $73.6 million in FCF versus $33.3 million a year ago. Operating cash flow margin hit 21%, up from 14%.
This beat is not a one-off. Management raised Q2 revenue guidance to $395M–$397M and full-year subscription ARR guidance to $1,854M–$1,862M, implying 18-19% ARR growth from the Q1 exit rate. Full-year FCF guidance of $293M–$303M implies a 18-19% FCF margin at the midpoint, consistent with Q1's performance. The guidance raise across all metrics — revenue, ARR, subscription ARR contribution margin, EPS, and FCF — suggests management sees the Q1 trajectory as durable, not a timing pull-forward.
Enterprise adoption is accelerating. Customers with $100K+ in subscription ARR grew 24% YoY to 2,946, and the average subscription dollar-based net retention rate remains above 120%. The product announcements in the quarter — data protection for Google Workspace, the SAGE AI governance engine, and the Microsoft Defender integration — extend Rubrik's platform from backup into identity recovery and agentic AI guardrails. The AHA preferred cybersecurity provider designation opens a channel into nearly 5,000 hospitals, a vertical with high data protection needs and long sales cycles that could compound growth in later quarters.
The GAAP picture is less flattering but improving. GAAP net loss narrowed to $(41.9 million) from $(102.1 million), or $(0.21) per share versus $(0.53). Stock-based compensation remained elevated at $73.4 million, essentially flat YoY, but as a percentage of revenue it fell to 19% from 26% — a sign that dilution is moderating as revenue scales. The company carries $1.13 billion in convertible notes against $1.75 billion in cash and short-term investments, a manageable net cash position.
Whether Rubrik can sustain the 13%+ ARR contribution margin as it invests in AI products and go-to-market expansion is the question for the rest of the year. The Q1 result suggests the operating leverage thesis is real, but the raised guidance implies management expects continued improvement, not just maintenance. If subscription ARR growth holds at 30%+ while contribution margins keep expanding, Rubrik is on track to reach GAAP profitability faster than the current consensus assumes. The Q2 print will test whether Q1 was an outlier or the new baseline.
