Columbia Banking (COLB) SVP Nixon Torran Forfeits & Withholds Shares

What Happened
Nixon Torran B, Senior Executive Vice President of Columbia Banking System, Inc. (COLB), reported two dispositions on Jan 20, 2026: 1,717 shares were forfeited (reported at $0) and 3,873 shares were withheld to cover tax withholding at $28.35 per share, valued at $109,800. These were not open-market sales—they relate to performance-based restricted stock units (PRSUs) and withholding for tax obligations.

Key Details

  • Transaction dates: January 20, 2026 (reported on Form 4 filed Jan 22, 2026).
  • Forfeiture: 1,717 shares disposed to issuer at $0.00 (per footnote F1 — PRSUs forfeited due to performance target not met).
  • Tax withholding: 3,873 shares disposed/withheld at $28.35 each, total ~$109,800 (footnote F2 — shares withheld to satisfy tax withholding upon vesting).
  • Shares owned after transaction: Not specified in this Form 4.
  • Filing timeliness: Reported on Jan 22 for transactions on Jan 20 (no late filing indicated).
  • Transaction codes: D = disposition to issuer (forfeiture); F = withholding to satisfy tax liability.

Context
These actions reflect equity award administration (forfeiture of PRSUs and share withholding for taxes), not an open-market sale or a purchase. For retail investors, withholding/forfeiture events are routine accounting/tax mechanics tied to equity awards and do not necessarily signal insider sentiment about the company.
