Columbia Banking System reported third quarter 2026 results that exceeded analyst expectations on both the top and bottom lines. Net income reached $220 million, supported by significant expansion in net interest margin and a successful customer deposit campaign that brought in over $700 million.

Key Highlights

  • Net interest margin expanded by 18 basis points sequentially to 4.11%, driven by higher loan yields and a favorable funding mix shift.
  • Total deposits increased to $52.7 billion, aided by a mid-year campaign that generated $700 million in new customer balances.
  • The Board of Directors authorized a new $1.2 billion share repurchase program following the completion of its previous capital return plan.
  • Credit quality remained stable with non-performing assets decreasing to 0.39% of total assets, down from 0.42% in the prior quarter.
  • Net interest income rose to $615 million, a 4% increase from the second quarter, benefiting from loan portfolio repricing and lower funding costs.
