Why Columbia Banking System’s latest earnings matter for shareholders

Columbia Banking System (COLB) reported first quarter 2026 earnings that came in below analyst expectations, with higher non interest expenses tied to the Pacific Premier integration weighing on profitability and raising new questions about earnings momentum.

The share price reaction to the earnings miss has been relatively contained, with a 1 day share price return showing a 2.12% decline but a 30 day share price return of 6.79%. The 1 year total shareholder return of 29.71% and 3 year total shareholder return of 92.72% point to a much stronger longer term picture.

With the stock trading at $29.56, an analyst target of $32.08, and an indicated intrinsic discount of about 54%, a key question arises: is Columbia Banking System still undervalued, or is the market already pricing in future growth?

Most Popular Narrative: 5.8% Undervalued

With Columbia Banking System trading at $29.56 versus a narrative fair value of $31.38, the current setup depends on how future earnings and margins develop under a 6.98% discount rate.

The planned acquisition and integration of Pacific Premier is positioned to expand Columbia's customer base and market reach in Western U.S. regions, with the potential to increase loan and deposit growth in these areas. This may have an impact on revenue and long-term earnings.

To understand what is behind that growth story and how it relates to a premium earnings multiple and higher profit margins, the narrative provides the full playbook.

Result: Fair Value of $31.38 (UNDERVALUED)

However, this depends on Columbia keeping integration costs under control and avoiding a sharper hit from any regional credit weakness that could pressure margins and earnings.

Another View: Earnings Multiple Sends A Different Signal

While the SWS DCF model suggests Columbia Banking System is trading at a large discount to its estimated future cash flow value of $64.20, the current P/E of 13.1x looks expensive next to peers at 11x and the wider US Banks industry at 11.4x, even though it sits below the fair ratio of 14.8x. For you, that mix of apparent upside on cash flows and a richer earnings multiple raises a simple question: which signal deserves more weight when risks around integration, funding and credit costs are already on the table?
