Context

• This was an equity award (RSUs) and a routine tax-withholding event — not an open-market sale or purchase signal. Withholding of shares to cover taxes on RSU settlement is common and does not necessarily reflect a decision to reduce stock exposure.
• The RSU grant vests over time per the issuer’s plan (footnote states vesting as to 1/3 on each of the first three anniversaries).
