Mr. Market is asking $24.4 billion for Rubrik at the 2026-10-13 close. As a Graham-style analyst, I start with proven results. In fiscal Q2 2027, the quarter ended 2026-07-31, revenue was $427.3 million, up from $309.9 million in fiscal Q2 2026, the quarter ended 2025-07-31, roughly 37.9% growth. Net loss was $61.8 million, or $0.30 per diluted share, better than the $95.9 million loss in the year-ago quarter. For FY2026, the fiscal year ended 2026-01-31, revenue was $1.3 billion with a net loss of $348.8 million and EPS of -$1.78. The company has lost money in each of the last four years, which is why the Lynch category is none. Still, trailing free cash flow is positive at $286.2 million. FairStock's FCF yield, using the 2026-10-13 close, is only 1.2% against the $24.4 billion market cap. FairStock's Altman Z-Score of 3.20 suggests balance-sheet distress is not immediate, while its Piotroski F-Score of 4/9 is middling. The business likely has switching costs in enterprise data protection, and RUBY may deepen the moat, but a wide moat is not yet proven by profits. The market cap is enormous relative to FY2026 revenue of $1.3 billion, leaving no margin of safety if growth slows. I would want sustained GAAP profits and much higher free cash flow before calling this a value investment.

In plain English: Rubrik sells data security and backup software to businesses. Sales are growing quickly and the company now brings in some cash, but it still loses money and has not reported a yearly profit. At the recent price near $118, the stock looks expensive compared with its sales and cash unless profits grow a lot from here.
