Key Details

• Transaction date: 2026-04-27; Form 4 filed: 2026-04-29 (timely).
• Acquired: 4,000 shares via exercise/conversion (reported at $0.00).
• Withheld/Disposed for tax: 1,181 shares @ $25.59 each = $30,222 (code F).
• Additional derivative line: 4,000 shares listed as disposed with N/A value (likely a conversion bookkeeping entry).
• Footnote: RSUs convert one-for-one into common stock (F1).
• Shares owned after transaction: not specified in the filing.

Context This appears to be a conversion/exercise of a derivative award (likely RSUs per the footnote) with a portion of the issued shares withheld to cover tax obligations — a common, routine administrative step rather than an open-market sale or purchase. The net effect: Hemby received shares through conversion while a portion was surrendered for taxes; no late filing was indicated.
