Context

• This was a routine tax-withholding transaction tied to RSU vesting (a common administrative disposition). It generally reflects payroll tax requirements rather than a signal about the insider’s view of the company. For derivatives or award-related dispositions, note that shares "disposed" for taxes reduce the net shares received from the award rather than representing a voluntary sale for cash.
