    Listen to the news

    Columbia Banking System has delivered a 75.9% total return over the past 3 years, which naturally raises a question for anyone looking at the chart today. Is the current share price being supported by the returns the bank earns on the capital it puts to work in its business?

    • The 75.9% gain over 3 years means long term holders now need to ask whether those past rewards line up with the underlying economics of Columbia Banking System's capital base.
    • For a regional lender like Columbia Banking System, the way it deploys deposits into loans and securities, and the profit it retains versus pays out, can heavily influence how efficiently it turns shareholder capital into earnings power over time.

    The issue now is whether Columbia Banking System's current valuation is fully explained by the returns it earns on its capital or if the market is pricing in something different.

    If you are weighing whether Columbia Banking System's recent 75.9% three year return lines up with the returns it earns on its capital, it can help to compare that pattern with companies in our 28 high quality undervalued stocks

    Is Columbia Banking System a Bargain on Excess Returns?

    The Excess Returns model looks at how effectively Columbia Banking System turns its equity base into profits above its own funding cost. In this framework, the bank is modeled with Book Value of $26.70 per share and Stable EPS of $3.27 per share, supported by an Average Return on Equity of 11.48%. Against a Cost of Equity of $2.28 per share, that translates into an Excess Return of $0.99 per share, which implies the franchise is expected to earn more than its investors require on the capital it employs.

    Those assumptions also build in a Stable Book Value of $28.48 per share, slightly above the current $28.73 share price. This helps explain why the Excess Returns projections put Columbia Banking System's estimated intrinsic value substantially above the current share price. For readers comparing banks, this kind of gap suggests the market price is not fully reflecting the modeled stream of returns on the equity base.
