TER TERADYNE, INC Insider Trading

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.

TER CEO Smith Gregory Stephen sells 8,597 shares (8.6K) at $338.98 under pre-arranged 10b5-1 plan; stock now -23.8% from 52-week high.

Smith Gregory Stephen, as President and CEO, executed a sale of 8,597 shares at $338.98 on 2026-05-15 under a pre-arranged 10b5-1 trading plan adopted on 2026-02-12, reducing his holdings from 133,066 shares to 124,469 shares. This transaction is scheduled rather than discretionary, eliminating timing as an analytical signal. Since the trade, TER stock has declined 23.8% from its 52-week high of $422.11, with the current price at $321.73, though this post-trade movement is unrelated to the insider's trading decision under a fixed plan. With a P/E of 58.92 and the company showing strong fundamentals (revenue growth of +13.1% annually, $398.9M net income in the latest quarter on $1.3B quarterly revenue), the sale does not materially alter the CEO's significant 124.5K-share remaining position.
