President sells 1,664 shares at $345.37–$355.00 via scheduled 10b5-1 plan; retains 15,721 non-derivative shares plus 8,532 in options
Shannon John Poulin, President of Semiconductor Test, executed 2 separate sales totaling 1,664 shares for $581,012.96 on consecutive trading days (May 21–22, 2026) at prices ranging from $345.37 to $355.00. These sales were part of a pre-arranged 10b5-1 trading plan adopted on 2026-02-19, indicating a scheduled, non-discretionary execution rather than a response to current market conditions. Post-transaction, Poulin retains 15,721 non-derivative shares (a 9.6% reduction from prior holdings) along with 8,532 stock options, preserving substantial ongoing exposure to Teradyne. The scheduled nature of the plan removes timing as a meaningful signal; this represents portfolio management through an established mechanism rather than a discretionary trading decision.
