Context
This filing reflects compensation-related RSU awards and a routine tax-withholding disposition, not an open-market sale for investment purposes. RSUs are a long-term equity award that convert to common shares when they vest (here, end of 2028). Tax-withholding by surrendering shares is a common administrative step and does not necessarily indicate buying or selling intent by the insider.
