With earnings, share buybacks and a new franchise focus all in play, the key question now is timing: is Columbia Banking System still trading at a discount, or are markets already pricing in future growth?

Most Popular Narrative: 5.8% Undervalued

Columbia Banking System's most followed narrative points to a fair value of $31.38 versus the last close at $29.56, so the story centers on modest upside built on detailed earnings and margin assumptions rather than a huge disconnect.

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, increasing loan and deposit growth as both population and economic activity continue to rise in these areas, this is likely to have a positive impact on revenue and long-term earnings.

Want to see what sits behind that expansion story, the revenue path, margin targets and future earnings multiple all have to line up. Curious which assumptions really carry this fair value, and how a single discount rate ties the whole narrative together.

Using a 6.98% discount rate, the narrative connects expected revenue growth, higher profit margins and a future P/E multiple to arrive at that $31.38 figure, with the current $29.56 price sitting slightly below it. Analysts in this narrative expect earnings and revenues to rise over time and apply a higher future earnings multiple than the broader US Banks industry to justify the fair value.

Result: Fair Value of $31.38 (UNDERVALUED)

However, this hinges on Columbia keeping credit costs and funding in check, since higher net charge offs or more expensive wholesale funding could quickly challenge that fair value story.
