Context

• These entries reflect RSU vesting/conversion and company withholding for taxes (a common, routine compensation event), not an open‑market sale or purchase. Per the filing, each RSU represents the right to one share (or cash in lieu, at the company’s discretion). This type of filing documents compensation settlement and tax withholding rather than a trading decision by the insider.
