Most Popular Narrative: 7.2% Undervalued

With Columbia Banking System's fair value estimated at $29.23 and the latest close at $27.14, the most popular narrative sees shares trading at a meaningful discount, setting up a debate around the path to realizing that upside.

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.

What numbers fuel this bullish thesis? The narrative is built on aggressive forecasts: revenue acceleration, fatter profit margins, and an earnings surge that would put Columbia among standouts in the sector. The playbook relies on a future profit multiple that is well below the industry. Want to know just how much growth is baked in? Only the full narrative reveals the high-stakes projections and the bold assumptions behind that fair value.

Result: Fair Value of $29.23 (UNDERVALUED)

While one method suggests shares are undervalued, comparing Columbia's price-to-earnings ratio of 17x to the industry’s 11.2x and the average peer’s 25.2x paints a mixed picture.
