Context
This was an equity award vesting (not an open‑market purchase or a deliberate sale). The withholding of shares to cover tax liabilities is routine and does not necessarily signal a change in insider sentiment. The award was performance‑based (PSUs) tied to multi‑year targets, as described in the filing footnotes.
