Context
This was primarily an equity award (RSUs) and routine tax-withholding (not an open-market sell). Tax withholding of shares is common when RSUs vest and does not necessarily indicate a change in the insider’s view of the company. The RSUs vest over three years (per F1), so a portion remains unvested and subject to future vesting conditions.
