AI Summary

6.0
Neutral

MKSI should now be viewed less as a cyclical recovery trade and more as an AI/advanced-packaging beneficiary with strong cash conversion and capital returns, but the stock's sharp rerating means the premium valuation must be justified by sustained execution despite leverage, margin mix risk, and limited 2026 visibility.
