Rubrik (NYSE: RBRK) stock gained 1.25% to $54.69 today after the cybersecurity and cloud data management company reported a powerful fourth-quarter performance that exceeded expectations across revenue, subscription growth, and free cash flow. The company closed fiscal 2026 with what CEO Bipul Sinha described as a “spectacular” quarter, driven by accelerating enterprise adoption and strong momentum in its cloud-based security platform.
Record subscription growth drives Rubrik’s strong quarter
The biggest highlight from Rubrik’s fourth quarter was its expanding subscription business. Subscription annual recurring revenue (ARR) reached $1.46 billion, representing a 34% increase compared with the previous year. The company also added $115 million in net new subscription ARR during the quarter, marking the largest quarterly ARR addition in Rubrik’s history.
Subscription revenue surged 50% year over year to $365 million, while total quarterly revenue rose 46% to $378 million. The strong performance reflects rising demand for cyber resilience and data security as enterprises continue shifting workloads to hybrid and multi-cloud environments.
Rubrik’s growth was also supported by its ongoing cloud transition. Cloud ARR climbed to $1.29 billion, up 48% from a year earlier, and now accounts for approximately 88% of total subscription ARR. Management said the company is nearing the end of its cloud migration phase, which has helped increase recurring revenue visibility and improve overall margins.
Enterprise customer expansion continues to accelerate
Customer expansion remained another major driver of Rubrik’s performance. The company reported subscription net retention above 120% in the quarter, meaning existing customers continue to increase their spending on the platform over time.
Rubrik ended the quarter with 2,805 customers generating more than $100,000 in subscription ARR, representing a 25% increase year over year. These enterprise customers now account for 87% of total subscription ARR, compared with 84% a year earlier.
The company also added a record 32 customers generating $1 million or more in subscription ARR, driving more than 50% growth in that cohort. According to management, expansion is being fueled by customers securing additional applications, protecting more data workloads, and adopting multiple security products within the Rubrik platform.
In fact, adoption of additional security products contributed more than 45% of subscription net retention in the quarter, up from 34% in the same period last year.
Profitability improves as margins expand
Beyond revenue growth, Rubrik also demonstrated improving profitability. The company reported a non-GAAP gross margin of 84% in the fourth quarter, compared with 80% in the prior year. The improvement was driven by stronger revenue performance and increased efficiency in hosting and infrastructure operations.
Rubrik also highlighted its subscription ARR contribution margin, a key operating leverage metric for the company. Over the last twelve months ending January 31, the contribution margin reached 12%, compared with just 2% in the previous year. Even when adjusting for one-time payroll tax expenses related to the company’s IPO, the margin improvement still represented a significant increase of roughly 730 basis points.
Free cash flow also showed dramatic improvement. For the full fiscal year, free cash flow reached $238 million compared with $22 million in fiscal 2025, representing more than a tenfold increase. Management attributed the improvement to higher sales, operating leverage, and optimization of the company’s capital structure.
Rubrik ended the quarter with approximately $1.7 billion in cash, cash equivalents, restricted cash, and marketable securities, alongside $1.1 billion in convertible debt.
Identity security and AI agent protection gaining traction
Rubrik’s product strategy is expanding beyond traditional data protection into cyber resilience and identity security. The company now offers two major platform suites: Rubrik Security Cloud for cyber resilience and Rubrik Agent Cloud for managing and controlling artificial intelligence agents.
Identity protection has quickly become one of the company’s fastest-growing products. Rubrik reported more than 900 customers using its identity security capabilities, up sharply from about 400 customers cited in the previous quarter. The company also emphasized its integration across Okta, Active Directory, and Microsoft Entra ID, positioning Rubrik as one of the few platforms capable of recovering identity infrastructure across multiple systems.
Rubrik Agent Cloud recently moved into general availability following a beta period. The platform helps enterprises discover AI agents within their environments, monitor their activity, and apply real-time guardrails that can allow or block agent actions. Management said several Fortune 500 companies are already testing the system through early proofs of concept.
Executives noted that competitive win rates against traditional data protection vendors exceeded 90% in the quarter, reflecting strong demand for modern cyber resilience solutions.
Growing demand tied to rising cyber threats and AI adoption
During the earnings call, management highlighted a broader market shift driving demand for cyber resilience platforms. As organizations deploy more AI tools and automation, the potential impact of data corruption, cyberattacks, or operational errors increases significantly.
CEO Bipul Sinha described Rubrik as a “system of record of last resort,” emphasizing the company’s role in helping enterprises recover critical data and identity infrastructure after cyber incidents.
The company also noted emerging demand related to sovereign cloud requirements, as governments and regulators increasingly push organizations to store sensitive data within specific geographic boundaries. While management said the total addressable market for sovereign cloud services is still evolving, it believes the trend could become another long-term growth driver.
Rubrik provides strong fiscal 2027 outlook
Looking ahead, Rubrik expects continued expansion across revenue, subscriptions, and cash flow. For fiscal 2027, the company forecasts subscription ARR between $1.829 billion and $1.839 billion, representing approximately 25% to 26% year-over-year growth.
Total revenue is projected to reach between $1.597 billion and $1.607 billion, while free cash flow is expected to range from $265 million to $275 million. The company also expects non-GAAP earnings per share between $0.07 and $0.27 for the year.
For the first quarter of fiscal 2027, Rubrik guided revenue between $365 million and $367 million, representing roughly 31% to 32% growth. Additional information about the company’s cybersecurity platform and product offerings can be found on Rubrik’s official website.
Why investors are watching RBRK stock
Rubrik’s strong fourth quarter highlights how rapidly the company is scaling within the cybersecurity market. With subscription ARR surpassing $1.4 billion, expanding enterprise adoption, improving margins, and rising free cash flow, the company is positioning itself as a major player in cyber resilience and cloud data security.
As enterprises continue investing heavily in protecting data, identities, and AI systems from cyber threats, Rubrik’s platform approach may allow it to capture a larger share of the growing cybersecurity market in the years ahead.
