Rubrik Clarifies Zero ARR From Strata Deal as Organic Net New ARR Growth Accelerates to 35%
Q2 fiscal 2027 earnings call, August 27, 2026
Rubrik delivered its tenth consecutive quarter of outperformance since going public, but the most consequential disclosure came in response to a pointed question from Barclays analyst Saket Kalia, who asked how much of the quarter's subscription ARR growth was inorganic following the company's Strata Identity acquisition. CFO Kiran Choudary was unambiguous: "In the most recent reported quarter, Q2, there was zero ARR from the Strata acquisition. And I also clarify that in the guidance we provided, there's an assumption of zero ARR as well. So both zero in the quarter, zero for the year." CEO Bipul Sinha reinforced the point, noting that net new ARR guidance for the fiscal year has been raised by $45 million, or more than 10%, since the start of the year, entirely on an organic basis.
That distinction matters because it undercuts a narrative some investors may have been building around acquisition-fueled growth. Instead, Rubrik's net new ARR grew 35% year-over-year this quarter, a sharp acceleration from prior periods, pushing subscription ARR to $1.66 billion, up 33% year-over-year. Management raised full-year subscription ARR guidance to $1.88 billion to $1.885 billion, implying roughly 29% growth, and lifted the implied net new ARR growth rate for the year from 7% to 14%, a 700 basis point increase versus the prior guide.
AI Threat Narrative Sharpens Around Mythos and Autonomous Attacks
Sinha leaned heavily into a framing the company has been building for years but which now has fresh evidentiary support: that AI models are enabling attacks at machine speed that render legacy detection and prevention tools obsolete. He pointed to Anthropic's Project Glasswing, in which Rubrik is a participant, and to a real-world incident involving Hugging Face, where "an autonomous AI agent exploit[ed] a zero-day vulnerability and gain[ed] unauthorized access to live systems, all without human direction." Sinha described this as demonstrating "both halves of the risk companies are grappling with, an AI orchestrated attack moving faster than any human speed response and an agent operating well outside the guardrails anyone intended for it."
The company's language around "Mythos and Frontier AI models" recurred throughout the call as a catalyst reshaping buyer psychology. Sinha argued that vulnerability chaining by AI models turns "low priority vulnerability into a P0 problem" and that "there is no real time between intrusion and breach," making preemptive recovery the only viable strategy rather than prevention or detection. KeyBanc's Eric Heath asked directly whether this narrative was translating into a demand inflection, and Sinha confirmed the company is seeing "acceleration in terms of the customers coming to us, having concerns about Mythos."
Rubrik Agent Cloud Crosses 15 Paying Customers, Still Excluded From Guidance
Rubrik Agent Cloud, the company's newer product suite for governing and securing enterprise AI agents, now has more than 15 paying customers, up from an unspecified smaller base previously. BMO's Keith Bachman pressed management on competitive dynamics, noting the governance pitch sounds similar to what identity providers already offer. Sinha pushed back, arguing that point solutions from observability and identity vendors don't match Rubrik's integrated approach: "Pretty much not many people are doing watching intent of AI agent with AI. That's unique that we brought into the marketplace." The company unveiled Rubrik Agent Identity during the quarter, extending existing identity infrastructure from Okta and Microsoft Entra ID into agent-level access decisions. Importantly, Choudary reiterated that "there's minimum assumption of RAC in this year's ARR," meaning any incremental contribution from this product line would represent upside not currently baked into guidance, a potential catalyst investors should watch for in coming quarters.
Identity Resilience Delivers Largest International Deal in Company History
Rubrik's Identity Resilience business, which the company has been building since launching Identity Recovery, notched what Sinha called "the largest international identity deal in Rubrik's history" this quarter. The customer had been experiencing multi-day recovery times, roughly seven days, and needed recovery in hours, a gap that Sinha said escalated the deal to CIO and CISO-level urgency. The company also highlighted a new capability, Identity Roll Forward, which allows customers to recover identity systems to a clean current state without losing legitimate business progress or leaving attacker persistence behind. Sinha emphasized that identity penetration within Rubrik's existing customer base remains early, suggesting a long runway for cross-sell.
Sovereign Cloud Trend Reviving Non-Cloud Business
A notable structural shift discussed on the call involves growth returning to Rubrik's non-cloud business, which had been shrinking as customers migrated to cloud deployments. Choudary confirmed that migrations are largely complete, and Sinha attributed renewed non-cloud growth to geopolitical dynamics: "every country is now concerned about containing their supply chain and economic infrastructure... this whole sovereign cloud and sovereign infrastructure is actually driving some trend towards non-cloud Rubrik sales." Cloud net new ARR grew 20% year-over-year, adjusted for migrations, according to Choudary, while non-cloud ARR is now growing again after years of decline, a dynamic U.S. Bank's Gray Powell flagged as underappreciated by investors fixated solely on the cloud metric. Choudary noted non-cloud business likely carries higher margins since Rubrik isn't hosting the infrastructure itself.
Hardware Costs and Tariffs Remain a Non-Issue
Despite broader industry concerns about rising hardware costs and supply constraints, Rubrik reported no material impact to subscription ARR, a point Choudary repeated across multiple analyst questions from Truist's Junaid Siddiqui and D.A. Davidson's Rudy Kessinger. Management attributed this resilience to Rubrik's software-centric model, noting that data center and hardware-adjacent revenue represents a shrinking minority of the overall business. Choudary added that hardware lead times have actually improved since the start of the year in the smaller regions, mainly parts of Asia Pacific, where Rubrik still sells hardware directly.
Margins Expand as Free Cash Flow Grows
Subscription ARR contribution margin improved 460 basis points year-over-year to 14% on a trailing twelve-month basis, and management guided to approximately 15.5% for the full fiscal year. Free cash flow reached $65.7 million in the quarter, up from $57.5 million a year earlier, with full-year guidance now calling for $323 million to $333 million. The company ended the quarter with $1.75 billion in cash and short-term investments against $1.13 billion in convertible debt, giving it ample balance sheet flexibility as it continues to invest in R&D and go-to-market expansion for Identity Resilience and Rubrik Agent Cloud.
