The shares were valued at $13.12 each, for a total of $106,115. This transaction is recorded as a disposition for tax withholding (transaction code F), not an open-market sale for cash.

Key Details

  • Transaction date: 2025-12-31; Filing date: 2026-03-25 (appears to be filed late relative to the 2-business-day Form 4 requirement).
  • Price per share: $13.12; Shares disposed: 8,088; Total value: $106,115.
  • Transaction code: F — payment of exercise price or tax liability (shares surrendered/withheld to cover taxes).
  • Shares owned after the transaction: not specified in the provided filing excerpt.
  • Filing timeliness: late filing may be noted; late Form 4s don’t by themselves indicate insider intent but do delay public disclosure.

Context

  • This type of transaction typically reflects tax withholding after exercising equity awards (a cashless or share-withholding method) and is routine for executives exercising options or receiving stock-based awards. Such withholdings are administrative and do not necessarily signal a personal decision to liquidate holdings for investment reasons.
