Context

Gifts are transfers and do not necessarily signal the insider’s view of the company’s prospects. They can be estate- or family-related transfers or other non-market moves.
The 560-share delivery was a routine tax-withholding action (shares surrendered to the company to cover taxes on vested RSUs), not an open-market sale.
