Rubrik is growing rapidly, with revenue up 38% and subscription ARR up 33%, but the stock remains hard to justify at a 555.6x forward P/E. The report rates RBRK a Hold as strong operating momentum collides with a demanding valuation and ongoing GAAP losses.
Rubrik, Inc. (RBRK) earns a Hold rating for a moderate-risk investor with a medium-term horizon. The business is growing quickly, expanding its recurring revenue base, and producing positive free cash flow, but the stock carries a demanding valuation while GAAP profitability remains negative. That combination creates a strong company and a less obvious stock purchase.
The operating evidence is strong. In Q2 fiscal 2027, Rubrik generated $427.3M of revenue, up 38% year over year, subscription ARR reached $1.66B, up 33%, and subscription net retention exceeded 119%. Management raised full-year fiscal 2027 guidance to $1.880B to $1.885B of subscription ARR, $1.685B to $1.693B of revenue, $0.47 to $0.53 of non-GAAP EPS, and $323M to $333M of free cash flow.
The counterweight is valuation and dilution. Rubrik's market capitalization is $19.8B, its reported forward P/E is 555.6x, and its free cash flow yield is 1.6%. Cash of $1.68B exceeds debt of $1.13B, but shareholders still face negative book value per share of $2.34 and weighted-average shares of roughly 230 million in the latest fiscal 2027 guidance.
Rubrik is a Palo Alto, California based software company serving the infrastructure software market. Founded in 2013 and listed on the NYSE after its April 25, 2024 IPO, the company had approximately 3,797 full-time employees as of January 31, 2026. Co-founder Bipul Sinha serves as CEO and chairman, while co-founder Arvind Nithrakashyap serves as CTO.
The company sells Rubrik Security Cloud, or RSC, for data security and cyber resilience, and Rubrik Agent Cloud, or RAC, for AI-agent operations. The platform covers enterprise data, unstructured data, cloud applications, SaaS applications, identity providers, threat analytics, recovery orchestration, and AI governance.
Rubrik reports its business through operating metrics rather than traditional revenue segments. Subscription ARR is the central scale measure. It reached $1.57B in Q1 fiscal 2027 and $1.66B by July 31, 2026. Cloud ARR reached $1.48B in Q2, while 3,084 customers generated at least $100,000 of subscription ARR.
The core RSC business remains the economic engine. Q1 subscription revenue was $374M, up 41% year over year, and Q2 subscription revenue was $407.2M, up 37%. Cloud ARR represented 89% of subscription ARR in Q1, showing that the multi-year transition from appliance-oriented deployments toward cloud delivery is nearing completion.
Identity is an important expansion vector. Rubrik's identity business grew 38% sequentially in Q1 to more than $50M of subscription ARR. Rubrik Agent Cloud is earlier in its commercial life, having become generally available in February 2026, but early proof-of-concept deployments have converted into production use, including a financial services customer using AWS Bedrock and Microsoft Copilot.
Geographic growth is broad. In Q1, Americas revenue increased 38% to $279M and revenue outside the Americas increased 43% to $108M. Fiscal 2026 international revenue reached $364.5M, up from $250.4M in fiscal 2025.

Rubrik Security Cloud is the flagship product because it combines backup, recovery, data security, identity protection, and threat analytics in one cloud-native control plane. Its architecture combines time-series data and metadata across enterprise, cloud, SaaS, unstructured data, and identity systems. That context supports policy automation, anomaly detection, sensitive-data discovery, attack analysis, and recovery workflows.
The Preemptive Recovery Engine is the product's clearest differentiator. It identifies clean recovery points before an attack, rather than beginning the recovery process after systems have been compromised. Native immutability, encryption, logical air gaps, role-based access controls, multifactor authentication, and secure protocols reinforce that design.
Rubrik Agent Cloud extends the same architecture into AI operations. Its four stated pillars are observability, identity, runtime security, and rewind. The product is designed to monitor AI agents, enforce policy at the tool-call level, and reverse destructive actions. That is a broader proposition than simply storing a backup, although the commercial contribution from RAC is still in its early phase.
Rubrik's advantage rests on a common data model rather than a single feature. The platform stores data and metadata as a self-describing time series, giving the threat engine information about application context, identity, data sensitivity, and lineage. Each additional protected workload adds context to the platform and creates more opportunities for cross-selling.
The company has added strategic assets to that platform. The Predibase acquisition supplied large-language-model fine-tuning and inference technology for the Semantic AI Governance Engine. The Strata.io acquisition expanded identity resilience, while the Anthropic Project Glasswing relationship gave Rubrik early access to the Claude Mythos research preview.
Q2 product activity was substantial. Rubrik launched Rubrik AI, expanded Agent Cloud for Anthropic's Claude Code, introduced Autonomous Business Recovery for cloud applications, advanced Rubrik Annapurna as an AI-ready unstructured data layer, and added Rubrik Agent Identity. Rubrik was also named a Leader in the 2026 Gartner Magic Quadrant for Backup and Data Protection Platforms for the seventh consecutive year.
The moat is forming, not finished. A 120% subscription net retention rate, 88% of subscription ARR from customers above $100,000, and rising identity adoption support platform stickiness. Against that, Commvault, Dell EMC, IBM, Veeam, Cohesity, and cybersecurity-focused vendors all have routes into portions of the same customer budget.
Rubrik operates primarily as a software company, which limits direct exposure to hardware inflation. Management said Q1 sales cycles remained stable and that rising hardware costs and supply constraints had no material impact on the business. Q1 free cash flow was $73.6M, compared with $36.8M in the year-ago quarter.
The remaining hardware exposure is concentrated. Rubrik relies on a limited number of contract manufacturers, and all Rubrik-branded appliances currently use servers designed and supplied by Super Micro Computer. The OEM agreement with Supermicro expires in November 2026, with annual renewal options and no minimum purchase requirement. The direct-to-distributor model lets channel partners order appliances directly from Supermicro.
Operational investment is directed toward research and development and targeted go-to-market expansion. R&D leadership spans Palo Alto, Tel Aviv, and Bangalore. Rubrik also sells through channel partners, system integrators, managed service providers, and cloud marketplaces operated by AWS, Azure, and GCP.
Rubrik's June 2026 Analyst Day outlined a $125B-plus total addressable market for 2029. The company divided that opportunity into $30B-plus of data management, $45B-plus of security and resilience, $10B-plus of identity, and $40B-plus of AI. Rubrik stated that the combined opportunity is projected to grow at a 20% compound annual rate from 2026 through 2029.
The market is shifting from isolated backup products toward cloud-native data protection, ransomware resilience, identity recovery, and data governance. Gartner reported worldwide software spending of $1.24T for 2025, up 14.0% year over year, and enterprise software cloud subscription revenue represented 60.1% of the 2024 market.
Rubrik's growth rate exceeds the broader software market. Q2 revenue increased 38%, normalized revenue growth was 43%, and subscription ARR grew 33%. The valuation therefore depends on continued share gains in a market where cloud migration, ransomware exposure, identity attacks, and AI-agent deployment are all expanding the number of protected workloads.

Rubrik serves financial services, retail, transportation, energy, industrials, healthcare, life sciences, education, public-sector organizations, technology, media, communications, and services companies. The customer base spans large global enterprises, government agencies, regulated industries, and smaller organizations reached through inside sales and partners.
Enterprise penetration is rising. Customers with at least $100,000 of subscription ARR increased to 3,084 in Q2, up 23% year over year, and customers with at least $1M of subscription ARR grew more than 50% in Q1. Those larger accounts represented 88% of subscription ARR. Subscription net retention above 119% shows that expansion within existing accounts is a central growth mechanism.
Recent customer examples support the platform thesis. A large UK public-sector organization replaced a decade-long incumbent and consolidated more than 400 legacy backup policies. A Global 2000 insurer selected Rubrik across on-premises and cloud workloads. A US agricultural organization added Entra ID and Okta protection after an Active Directory ransomware attack.
Rubrik competes across three overlapping groups. The first includes data protection vendors such as Commvault, Dell EMC, IBM, Veeam, and Cohesity. The second includes smaller cloud and SaaS data management vendors. The third includes cybersecurity companies focused on ransomware detection, identity resilience, data security posture management, data classification, insider threats, and incident containment.
Cohesity is a particularly important strategic rival after its acquisition of the Veritas data protection business. Commvault and Veeam remain established backup and recovery competitors, while Dell EMC and IBM bring large enterprise installed bases. Rubrik counters those advantages with a cloud-first architecture that combines recovery, threat analytics, identity, and data security.
The competitive test is platform breadth versus specialized depth. Rubrik offers one control plane and an API-first architecture, while point vendors can focus more narrowly on a specific identity, data governance, or security workflow. Microsoft and CrowdStrike integrations improve Rubrik's ability to fit into existing enterprise security stacks, but they also place the company inside a crowded ecosystem where larger vendors can bundle adjacent capabilities.
The strongest macro driver is the rise of AI-enabled cyber risk. CEO Bipul Sinha said autonomous agents can intrude, breach, and encrypt at machine speed, while AI agents increasingly run business processes involving identity and sensitive data. That threat profile increases the value of preemptive recovery, identity protection, and agent-level controls.
Geopolitics is also shaping deployment choices. Management cited growing interest in sovereign infrastructure across Europe and the Middle East because of data locality and sovereignty requirements. Rubrik announced a $500M UK investment and designated London as its EMEA headquarters. These developments support regional expansion while increasing the importance of compliance, residency, and regulated-industry capabilities.
Hardware inflation is a smaller macro risk for the current model because management reported no material Q1 impact and described Rubrik as primarily a software company. The more relevant macro sensitivity is enterprise technology spending. Rubrik's 27% fiscal 2027 subscription ARR growth guide assumes continued investment in data security, identity, and AI despite broader budget discipline.
Cash of $1.68B exceeds debt of $1.13B, but Rubrik still carries negative book value per share of $2.34 and dilution risk from roughly 230 million weighted-average shares.

Get Full Access →Rubrik has built a credible growth platform around cyber resilience rather than traditional backup. Subscription ARR of $1.66B, net retention above 119%, 3,084 large customers, and Q2 revenue growth of 38% show that the core business is gaining scale. The Preemptive Recovery Engine, identity expansion, and Agent Cloud give the company multiple paths to deepen customer relationships.
The investment case is strongest when valuation discipline stays in control. Cash exceeds debt, free cash flow is positive, and management raised fiscal 2027 guidance, but negative GAAP earnings, negative equity, 555.6x forward P/E, and a 1.6% free cash flow yield keep the risk profile above that of a mature software compounder. At $105, the shares earn Hold: a high-quality growth story that deserves monitoring, but not an unlimited price.
