Chao James 4

What Happened

Context

• This was a standard RSU vesting and tax-withholding event, not an open-market sale or purchase. The withheld shares represent a cashless settlement to cover taxes and do not by themselves indicate a change in insider sentiment. The filing uses transaction code M for conversion/exercise of a derivative (RSU conversion) and F for shares withheld to satisfy tax liabilities.
