Columbia Banking System's share price recently reversed course with a strong 5% gain over the last week, easing some of the month’s mild weakness. Momentum has been steady rather than explosive, and while the year-to-date share price performance is down nearly 5%, long-term shareholders have still enjoyed a healthy 60% total return over the past five years. With this kind of track record, interest in the stock’s next chapter is understandable.

Most Popular Narrative: 12.6% Undervalued

Columbia Banking System’s last close of $25.54 sits well below the most popular narrative’s fair value estimate of $29.23. This setup reflects optimism among analysts who anticipate the company can outperform modest market expectations despite its measured recent performance.

The planned acquisition and integration of Pacific Premier is positioned to significantly expand Columbia's customer base and market reach in high-growth Western U.S. regions. This is expected to increase loan and deposit growth as both population and economic activity continue to rise in these areas. Such growth is likely to have a positive impact on revenue and long-term earnings.

Another View: The Multiples Story

Shifting to another widely used lens, Columbia Banking System’s price-to-earnings ratio currently stands at 14.5x. While this looks expensive versus the US Banks industry average of 11.2x, it is seen as good value against the peer average of 25.2x and sits below the fair ratio of 17.8x, which is where the market could move to over time. This spread suggests there may be valuation risk if banking sector sentiment shifts, but also opportunity if the company closes the gap to its fair ratio.
