Arnold Colleen 4/A

What Happened

Context

• This was not an open-market sale by the insider — the 2,053-share disposition was a cashless surrender to the company to cover tax liabilities on vested equity, which is common and routine. Vesting at 63.58% indicates partial payout of performance-based units relative to target; such vesting results from pre-set performance measures and does not itself signal an insider buying or selling in the market.
