Context
This was not an open-market purchase or sale — the acquisitions were the result of vested PSUs and released DERs (typical executive compensation vesting). The disposition was a share surrender to cover tax withholding, a routine administrative action that does not necessarily signal a change in the insider’s view of the company.
