Driscoll Ryan 4

What Happened

• Ryan Driscoll, Vice President, General Counsel and Secretary of Teradyne (TER), had shares withheld by the company to satisfy tax withholding obligations tied to restricted stock unit (RSU) vesting. On Jan 27, 2026, 113 shares were withheld at $238.94 for ~$27,000, and on Jan 28, 2026, 82 shares were withheld at $250.48 for ~$20,539 — total proceeds roughly $47,539. These transactions are recorded as dispositions (code F) and reflect tax withholding rather than an open-market sale.

Context

• These were tax-withholding dispositions (code F), a common, routine administrative action when RSUs vest; they do not necessarily indicate the insider is selling shares for investment reasons. For retail investors, such withholding is less informative than open-market purchases, though it does confirm RSU vesting and dilution timing.
