Context

• These entries reflect routine RSU vesting and conversion to shares (derivative exercises at $0) rather than an open-market purchase or sale. The remittance of shares to the company to cover tax withholding is common and is noted as an exempt disposition under Rule 16b-3(e). This filing does not indicate a separate open-market sale or purchase.
