CFO Ramakumar Mayampurath sells 8,810 MKSI shares ($2.8M) via 10b5-1 plan; retains 1 share post-transaction.
Ramakumar Mayampurath, EVP & CFO of MKS Inc, executed a sale of 8,810 shares at $315.48 on 2026-05-22 totaling $2,779,378.80 as part of a pre-arranged 10b5-1 trading plan adopted on 2026-02-20. This sale represents a -100.0% reduction of his pre-transaction holdings of 8,811 shares, leaving him with 1 share post-transaction. The current market price stands at $332.13, which is +1.6% from the 52-week high of $326.84, in a context where the stock has posted a +18.2% 30-day return and +29.8% 90-day return. The scheduled nature of this transaction under a 10b5-1 plan removes discretionary timing from the execution, and the near-complete liquidation of his position warrants investor attention given the substantial holding being disposed of.
