Context
- These were not open-market sales; the “disposals” were company withholding of shares to cover taxes (a common cashless-withholding method), not a voluntary sale.
- RSUs are a form of equity compensation that convert to shares upon vesting; withholding reduces the number of shares actually issued to the insider.
- This filing is informational about compensation and tax withholding rather than a directional buy or sell signal.
