Context

These entries reflect a routine compensation settlement (PSUs vesting) rather than a discretionary buy or sell; withholding of shares for taxes is common and does not necessarily indicate a change in insider sentiment.
The conversion price of $0.00 indicates these were equity awards (PSUs) converting to shares, not option purchases requiring cash outlay.
