Key Details

• Transaction date: 2026-02-02; filing date: 2026-02-04 (timely Form 4).
• Reported instrument types/codes: A = Award/Grant (28,927 shares / $858,843 and 21,988 shares / $652,824); F = Tax withholding (11,383 shares / $337,961 and 8,653 shares / $256,908).
• Vesting tied to performance conditions: awards granted Feb 21, 2023 and Mar 15, 2023 vested based on Columbia’s relative return on tangible common equity for fiscal years 2023–2025 versus a Compensation Committee-approved peer group (see footnotes).

Context

• These were PRSU vesting events, not open-market purchases or sales; the "dispositions" reflect shares withheld to cover tax obligations (common for equity compensation), not indicative of an open-market sale.
• No 10b5-1 plan, option exercise, or gifts are indicated in the filing. The filing appears timely (filed within the SEC’s two-business-day window).
