Insights
Insider RSU vesting and tax-withholding sale changed direct holdings by 3,842 shares.
The filing documents a standard executive compensation event where 10,840 RSUs vested into common stock on 10/01/2025, raising reported direct holdings to 16,659 shares. The subsequent 3,842 share disposition on 10/02/2025 was used to satisfy tax obligations and reduced holdings to 12,817 shares.
This pattern is administrative and common after vesting; it reflects compensation realization rather than an opportunistic open-market sale unconnected to vesting.
RSU grant from 2021 completed its four-year vesting, converting to shares with tax withholding.
The explanation states the RSUs were granted on 10/01/2021 and vested on the fourth anniversary, yielding 10,840 shares. The filing explicitly notes 3,842 shares were withheld to cover tax obligations.
From a pay-structure view, this confirms the grant schedule executed as intended and that net new shares retained by the executive after tax withholding are 6,998 from this vesting event.
