Context

• This was not an open-market purchase or sale for investment purposes but the vesting of a performance-based equity award; withholding shares for taxes is a common administrative step and does not necessarily indicate a buy or sell signal. The award vested above target (147%), reflecting the specific performance metric in the award terms.
