Context

• This was an exercise of compensation-related derivative awards (SARs) with shares surrendered/ sold to cover tax obligations and/or satisfy issuer withholding — effectively a cashless exercise. Such transactions are commonly part of routine executive compensation and do not, by themselves, indicate the insider’s view on the company’s stock.
