Moore Devine David 4

What Happened

• David Moore, EVP & Chief Marketing Officer of Columbia Banking System (COLB), recorded dispositions on Jan 20, 2026: 260 shares were forfeited back to the issuer (reported at $0.00), and 628 shares were withheld to satisfy tax withholding obligations. The withheld shares were valued at $28.35 each, totaling about $17,804. These are not open-market purchases or sales by the insider; the 260-share disposition was a forfeiture tied to performance RSUs, and the 628-share action was routine tax withholding.
