Context

This was not an open‑market sale or purchase; it was primarily vesting of RSUs and exercise/conversion of derivatives followed by net share settlement to cover taxes. Net share settlement (company withholding shares) is routine and does not reflect an open‑market sale by the insider.
For retail investors: vesting and tax‑withholding transactions are common compensation events for executives and are not the same signal as a voluntary sale or purchase in the market.
