Company Overview
Created through the merger of two Pacific Northwest banking institutions with deep regional roots, Columbia Banking System (NASDAQ: COLB) operates Umpqua Bank, providing commercial, consumer, and wealth management services across eight western states.
Sales Growth
In general, banks make money from two primary sources. The first is net interest income, which is interest earned on loans, mortgages, and investments in securities minus interest paid out on deposits. The second source is non-interest income, which can come from bank account, credit card, wealth management, investment banking, and trading fees. Luckily, Columbia Banking System’s revenue grew at an incredible 34.4% compounded annual growth rate over the last five years. Its growth beat the average banking company and shows its offerings resonate with customers.
Long-term growth is the most important, but within financials, a half-decade historical view may miss recent interest rate changes and market returns. Columbia Banking System’s annualized revenue growth of 14.8% over the last two years is below its five-year trend, but we still think the results suggest healthy demand. 
Note: Quarters not shown were determined to be outliers because they were impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.
This quarter, Columbia Banking System pulled off a wonderful 32.1% year-on-year revenue growth rate, but its $677 million of revenue fell short of Wall Street’s rosy estimates.
Net interest income made up 89.8% of the company’s total revenue during the last five years, meaning Columbia Banking System barely relies on non-interest income to drive its overall growth.
Net interest income commands greater market attention due to its reliability and consistency, whereas non-interest income is often seen as lower-quality revenue that lacks the same dependable characteristics.

Tangible Book Value Per Share (TBVPS)
Banks profit by intermediating between depositors and borrowers, making them fundamentally balance sheet-driven enterprises. Market participants emphasize balance sheet quality and sustained book value growth when evaluating these institutions.
Because of this, tangible book value per share (TBVPS) emerges as the critical performance benchmark. By excluding intangible assets with uncertain liquidation values, this metric captures real, liquid net worth per share. Other (and more commonly known) per-share metrics like EPS can sometimes be murky due to M&A or accounting rules allowing for loan losses to be spread out.
Columbia Banking System’s TBVPS declined at a 1.7% annual clip over the last five years. However, TBVPS growth has accelerated recently, growing by 8.7% annually over the last two years from $16.26 to $19.22 per share.
Over the next 12 months, Consensus estimates call for Columbia Banking System’s TBVPS to grow by 10.2% to $21.19, mediocre growth rate.
