  • F3/F5: The withheld shares relate to tax withholding on vesting/delivery of RSUs granted on March 24, 2022 and March 14, 2024.

Context

• Transfers to a family trust (gift code G/F1) are internal estate/planning moves and do not necessarily signal buying or selling intent in the market.
• The share surrenders at $109.60 were tax withholdings associated with RSU vesting (routine; not open-market sales). This is different from an open-market sale, where shares are sold to outside buyers.
• Several RSUs referenced remain unvested per the footnotes, so additional withholding or deliveries could occur on future vesting dates.
