Rubrik Stock Analysis: A Cybersecurity Stock You Need to Buy as AI Agents Proliferate?

Summary

Parkev states that Rubrik has seen a significant acceleration in subscription revenue, growing 37% as enterprises seek resilience against AI-orchestrated attacks. Parkev argues that the company is in a strong position due to the proliferation of agentic AI, leading to trailing 12-month revenue of $1.54 billion, which has more than doubled since early 2024. Parkev notes that while the company is currently losing money with a negative 18.3% operating margin, there is potential for long-term profitability similar to industry leaders if Rubrik can achieve sufficient scale over the next several years.

Parkev argues that the stock's valuation is currently a primary concern, with a forward price-to-earnings ratio of 115. Based on a discounted cash flow analysis, Parkev states that the fair value for the stock is approximately $68 per share, which is about 22% lower than the current price of roughly $89. Parkev concludes that while the outlook for Rubrik is more positive than at the start of the year, investors should wait for a better entry point.
