Key Details

  • Transaction date and price: June 28, 2026 — 1,269 shares at $15.49 each (total $19,657).
  • Transaction type: Code F — payment of exercise price or tax liability (shares withheld/used to cover taxes).
  • Filing date: June 30, 2026 (filed two days after the transaction), which is timely for a Form 4 reporting period.
  • Shares owned after transaction: Not specified in the reported data.
  • Footnotes on the Form 4 note vesting schedules: restricted stock vests at 20% per year beginning June 28, 2023 (F1) and other grants/options vest at various dates (F2–F5), suggesting the withholding likely relates to vesting/exercise of awards.

Context Tax-withholding dispositions (code F) are routine administrative transactions that do not necessarily indicate insider sentiment; they are commonly used to cover taxes or exercise costs when restricted stock vests or options are exercised. The filing shows vesting schedules for restricted stock and options, implying the withheld shares were used to satisfy tax or exercise obligations tied to those awards.
