AI Summary

6.0
Neutral

Rubrik's shift into a cyber-resilience and AI-security platform supports sustained mid-30% ARR growth and improving cash generation, but RBRK's premium valuation requires proof that new AI modules drive measurable enterprise cross-sell and margin expansion rather than higher spending and dilution.
