Context

• This is a routine RSU vesting and share-withholding for taxes (a “cashless” withholding), not an indication of an open-market buy or sell. Such transactions reflect compensation being settled into stock rather than insider sentiment about the stock.
• For retail investors: purchases or open-market buys by insiders are often more informative than routine vesting/withholding events.
