Columbia Banking System stock slips 1.44 percent after debt issue

Columbia Banking System stock was trading at USD 28.92 on Nasdaq on September 23, 2026, down 1.44 percent from the previous close and 14.1 percent below its 52-week high of USD 33.68. The latest capital action gives the regional bank a concrete balance-sheet storyline.

Subordinated notes add capital

On September 14, 2026, Columbia Banking System announced the pricing of USD 250 million of subordinated notes carrying an initial fixed interest rate of 6.721 percent and maturing in 2036, according to Columbia Banking System.

The notes are intended to qualify as Tier 2 capital. Columbia said it plans to use the proceeds for general corporate purposes, growth and capital adequacy, while potentially returning up to USD 250 million to the holding company for the redemption of trust preferred securities.

EPS beat revenue expectations

For Q2 2026, Columbia reported EPS of USD 0.76 against a consensus estimate of USD 0.73, a USD 0.03 beat. Revenue reached USD 677.00 million, which was USD 10.40 million below the USD 687.40 million expectation, according to MarketBeat.

The split between earnings and revenue matters: the per-share result exceeded expectations, while the top line fell short by 1.5 percent. That leaves capital strength and operating efficiency as the more important balance-sheet questions after the new debt issue.

Stock stays below yearly high

At USD 28.92, the stock had a market capitalization of USD 8,177,992,935 on September 23, 2026. Its 52-week range was USD 23.83 to USD 33.68, putting the current quote USD 5.24 above the low and USD 4.76 below the high.

Columbia Banking System operates through Columbia Bank and provides commercial, consumer, mortgage, wealth-management and treasury services. The combination of a USD 0.03 Q2 EPS beat and a USD 250 million capital raise gives investors two measurable reference points for assessing the shares.
