Schreiner James Alan, EVP & COO at MKS Instruments (MKSI), has demonstrated a consistent pattern of selling activity over 23 reported transactions, with no recorded purchases. Since July 2025, Schreiner has executed multiple sales totaling approximately $3.74 million, all concentrated in MKSI shares. The most recent transactions include a $1.05 million sale on February 24, 2026, and two derivative dispositions on February 17, 2026, each valued at $1.13 million. Earlier sales in 2025 were smaller in scale, ranging from $98,035 to $125,175, suggesting an acceleration in the size of disposals in early 2026.
The filings show no open-market buying activity, with all transactions coded as sales (S), derivative dispositions (F), or awards (A/M) with no reported value. The absence of purchases and the repeated divestments indicate a clear directional bias toward reducing exposure to MKSI. While the February 2026 filings include multiple award-related entries, the monetization of holdings through sales remains the dominant theme in Schreiner’s trading history. The data reflects a sustained reduction in equity exposure rather than periodic rebalancing, given the lack of offsetting acquisitions.
