Context
The dispositions here are tax‑withholding transactions tied to RSU vesting (routine administrative actions), not open‑market sales. The new RSU grant is a compensation award subject to future vesting; it is not an immediate purchase. These entries are informational for investors tracking insider compensation and potential future share dilution.
