Context
These were performance-based restricted stock units vesting after a three-year performance period; the award reflects partial achievement of metrics measured through 2025. The 102-share disposition was a routine tax-withholding (not an open-market sale), which is common when equity awards vest and does not, by itself, imply a personal investment decision. Transaction codes: A = award/grant, F = tax withholding.
