Why One Investor Says Rubrik's 6x Revenue Multiple Is Too Cheap

An individual investor who opened a Rubrik (RBRK) position in December 2025 argues the stock deserves a richer multiple. The thesis relies on revenue growth that has accelerated, margin expansion, and a market in data security and backup that the investor sees as underappreciated by the current price.

Rubrik reported fiscal 2026 fourth-quarter revenue of $280 million, up 38% from a year earlier. Subscription revenue made up 94% of that total. Gross margin hit 76%, up from 72% in the same quarter last year. The company guided for fiscal 2027 revenue between $1.18 billion and $1.20 billion. At the midpoint, that represents growth of roughly 25%. The cybersecurity software sector average is about 15%, according to consensus estimates.

The investor's central claim is that the market is pricing Rubrik as if it will stay unprofitable for years. A GAAP operating loss of $78 million in the latest quarter is the headline number. Free cash flow turned positive at $12 million. The company expects to be free cash flow positive for the full fiscal year. The investor sees that inflection as a reason for a higher earnings multiple.

A skeptical view focuses on the competitive field. CrowdStrike (CRWD) and Dell (DELL) both offer data protection products that overlap with Rubrik's backup and recovery business. CrowdStrike's Falcon platform includes cloud workload protection. Dell's PowerProtect line is entrenched in enterprise data centers. AlphaScala's proprietary scoring rates CRWD at 49 out of 100 (Mixed) and DELL at 64 out of 100 (Moderate), reflecting the mixed competitive dynamics.

The broader cybersecurity sector has compressed on valuation over the past year. Many SaaS and security stocks contracted as investors rotated toward AI and hardware plays. Rubrik's enterprise value-to-revenue multiple sits near 6x. The median for high-growth security software companies is about 8x. That spread could narrow if the company sustains its growth and margin trajectory.

Risks include execution toward GAAP profitability, customer concentration, and the potential for larger rivals to bundle competing products at lower prices. Rubrik's largest customer accounted for about 4% of revenue in the latest quarter. Net dollar retention of 120% suggests existing customers are expanding spend.

The next scheduled catalyst is Rubrik's fiscal first-quarter earnings report, expected in early June. The investor said they plan to hold through that report and add on any pullback. For now, the case rests on whether the market will re-rate a company that is growing faster than peers while approaching sustained free cash flow generation.
