Context

This was not an open-market buy or sale by the insider but routine RSU vesting with shares withheld to satisfy tax withholding — a common practice that does not necessarily signal the insider’s buy/sell sentiment. For retail investors, purchases are generally more informative as bullish signals; this filing documents compensation vesting and tax withholding rather than an intentional sale.
