Context

• The filing shows an option exercise immediately followed by a sale of those 5,000 shares, consistent with a cashless exercise or quick resale of exercised shares (both the acquisition and disposal of the 5,000 shares are reported).
• The RSU entries are not market sales — they reflect a deferral election into a retirement plan and do not necessarily indicate a change in economic exposure until paid.
