Namdar Frank 4

What Happened

• Frank Namdar, EVP & Chief Credit Officer of Columbia Banking System (COLB), had 2,820 restricted stock units (RSUs) vest on March 13, 2026. The vested shares are reported at $26.23 each for a gross value of $73,969. To satisfy tax withholding, 1,367 of those shares were withheld (disposed) valued at $35,856, leaving a net of 1,453 shares retained (net value ≈ $38,113).

Key Details

• Transaction date: 2026-03-13. Vesting/conversion reported as code M (exercise/conversion of derivative); tax withholding reported as code F.
• Prices reported: $26.23 per share (used to value the vested shares and withholding).
• Shares acquired: 2,820; shares withheld for taxes (disposed): 1,367; net shares retained: 1,453.
• Footnote: These were Restricted Stock Units granted Feb 25, 2025 that vest in three annual installments beginning March 13, 2026 (RSUs convert one-for-one into common stock).
• Filing timeliness: Report filed 2026-03-17 for a 2026-03-13 transaction — within the typical 2 business-day Form 4 window.
• The filing shows a $0.00 derivative line consistent with RSU conversion/reporting mechanics; this does not indicate an open-market sale.

Context

• This was a scheduled RSU vesting event (an award converting into shares), not an open-market purchase or a voluntary sale; the withholding of shares to cover taxes is a common administrative step (cashless tax withholding). Vesting events generally reflect prior compensation grants rather than real-time bullish or bearish trading by the insider.
