Rubrik's high switching costs and emerging AI-security demand underpin growth that looks attractively valued. At 12.9x forward EV/sales, it trades below the cybersecurity peer median relative to expected revenue growth. Subscription ARR grew 32.6% YoY and net dollar retention reached 119%. Agentic AI security adoption remains early; non-GAAP operating margin hit 7.8%, though GAAP net income remains negative partly due to stock-based compensation. x.com 

Rubrik is a decent way to own cybersecurity at about 9x next-twelve-month revenue, while CrowdStrike, Cloudflare and Palo Alto Networks valuations look ridiculous. It still needs to improve margins and reduce dilution. x.com 

Rubrik is too expensive now against a $70-80 valuation, even though its very strong platform drives nearly 40% growth that can continue for many years as a cybersecurity and data-recovery play. x.com 

Rubrik has become part of the cybersecurity infrastructure layer in the agentic AI era, agnostic to models, chips and clouds. Strong CrowdStrike and Okta reports should mean a substantial beat and raise, and maybe a rerating. If that doesn't come, it would raise questions, as security starts sorting into winners and not-winners. x.com  x.com 

Rubrik should not be compared with SentinelOne because Rubrik generates real free cash flow. SentinelOne began decelerating before reaching $1 billion of revenue, while Rubrik is likely to exceed $2 billion and still grow at around 20% a year. Concerns about subscription billings timing miss the point; the past three years of cash generation show the trend. x.com  x.com 

Rubrik is in a dangerous place, one deceleration away from growth in the 20s while still sub-scale. Palantir is a better company at a much better multiple and is accelerating while sustaining triple-digit growth. Rubrik would be worth a solid bet in the $60s or $70s, but on current fundamentals it shouldn't be more than a 5% position. x.com 

Rubrik is a top-tier company in a top-tier sector, one of the first to tackle agentic AI security, and well on its way to becoming a $50B cybersecurity leader this decade. Q2 revenue rose 38% to $427.3M versus $396.3M expected, subscription ARR grew 33% to $1.66B and cloud ARR 39%, with a 15% free-cash-flow margin. Cybersecurity's TAM keeps expanding, with giants like Palo Alto Networks, Cloudflare and CrowdStrike still growing double digits. x.com 

Rubrik crushed earnings, as strength in cybersecurity and good management delivered well above expectations even though the stock is not cheap. Revenue was $427 million versus $387 million expected, up 38%, and EPS of $0.20 beat the $0.04 expected. CEO Bipul Sinha's pre-earnings post that cyber resilience is the only real cybersecurity strategy in the post-Mythos era signaled confidence. x.com  x.com  x.com 

Rubrik belongs in the too-hard pile until it proves it can make money and stop diluting shareholders. @InvestingVisual notes that net losses, dilution and stock compensation as a share of revenue are shrinking each quarter, but trending in the right direction is not good enough for a large investment; continued proof over time could prompt a rethink. x.com  x.com 

Rubrik is worth buying because selling cybersecurity in the SaaS selloff was the most obvious miscalculation, as fears that AI tools like Claude would put such companies out of business were misplaced. x.com
