  • Price: $4.61 per share; Shares withheld/disposed: 91,374; Total value: ~$421,234.
  • Transaction code: F — shares withheld to satisfy tax liability on RSU vesting.
  • Shares owned after transaction: not specified in the provided filing details.

Context
Tax-withholding dispositions on RSU vesting are routine administrative actions and do not indicate an open-market sale or necessarily reflect the insider's view of the company. This was not an option exercise or a 10b5-1 sale plan; it was a cashless withholding to cover taxes on vested equity.
