Context

• These transactions are compensation-related (RSU grant and tax withholding), not open-market purchases or discretionary sales. Withholding shares to cover taxes is a routine, non-market-sale settlement of vested equity and does not necessarily indicate the insider’s personal decision to sell shares on the open market.
