MKSI MKS INC
Price Chart
Executive Summary
Three MKSI insiders sold shares totaling $2.62M over one week following strong Q1 earnings. The sales represent just 0.012% of market cap and include the EVP & GC and an EVP. Director grants (non-cash) also occurred. Given the trivial dollar amount relative to a $21.2B market cap and the proximity to a well-received earnings beat, the cluster appears to be routine profit-taking or liquidity-driven, not a bearish signal.
Key Financial Metrics
Actionable Insight
The insider selling volume is immaterial. Monitor Q2 2026 results for any change in fundamentals; the cluster does not warrant defensive action.
Key Facts
- Total insider sales of $2.62M are 0.012% of MKSI's $21.2B market cap
- Two EVPs sold: Burke Kathleen Flaherty (EVP, GC & Secretary) sold $1.39M, Taranto Eric Robert (EVP & GM, VSD) sold $911K
- Director Moloney sold $312K; seven directors received non-cash grants totaling 781 shares each
- Sales occurred within 9 days after Q1 2026 earnings beat: revenue $1.078B (at high end), Non-GAAP EPS $2.30 (above guidance)
Financial Impact
Total insider sales of $2.62M, negligible relative to $21.2B market cap
Risk Factors
- Convertible notes reclassified to short-term debt may create overhang if conversion occurs
- Future insider selling acceleration could signal caution, but current pattern is routine
