(“Columbia”) (Nasdaq: COLB), announced today the pricing of its offering of $250 million aggregate principal amount of its 6.721% Fixed-to-Fixed Rate Subordinated Notes due 2036 (the “Notes”). The offering of the Notes is expected to close on September 18, 2026, subject to customary closing conditions.
