Context
Withholding shares to cover taxes is a routine administrative step when RSUs vest; the company retains or cancels the withheld shares to satisfy tax obligations. This is different from a voluntary open-market sale and does not necessarily signal the insider’s view of the stock. The underlying RSU grants and their original reporting dates are referenced in the footnotes and earlier filings.
