Context

This was a tax-withholding disposition tied to vesting of PSUs and RSUs (common compensation mechanics), not an open-market sale indicating a change in investment view. In simple terms: the company withheld a portion of the vested award shares to cover the executive's tax bill, and those withheld shares are reported as disposed.
