Rubrik (RBRK) is back in focus after unveiling its Semantic AI Governance Engine, SAGE, along with a new integration with Microsoft Defender, two launches aimed at tightening security around enterprise AI and identity systems.

See our latest analysis for Rubrik.

The SAGE and Microsoft Defender announcements arrive during a choppy period for Rubrik, with a 12.49% 7 day share price return and 5.87% 1 day share price return following a 31.84% year to date share price decline and a near flat 1 year total shareholder return of 0.64% decline.

Another Angle on Rubrik's Valuation

While the analyst narrative points to a fair value of $86.71 and labels Rubrik as undervalued, the current P/S ratio of 7.9x tells a different story. It sits above the US Software average of 3.6x and above Rubrik's own fair ratio of 7.3x, which points to valuation risk if sentiment cools.
