Columbia Banking System (COLB) is shifting its focus from transactional loans to full relationship banking after closing the Pacific Premier deal. The transition aims to boost earnings through granular deposits, an expanded Western footprint, and fee platforms.

Management plans to decrease $8 billion of inherited transactional loans over eight quarters, reallocating capital to relationship-driven commercial and industrial (C&I) and owner-occupied CRE loans.

Columbia Banking’s strategy is timely, improving net interest margin (NIM) to 3.84% in Q3 2025 from 3.56% a year earlier. With disciplined pricing, loan growth may remain muted as runoff offsets originations until around 2027.

As relationship loans grow, the Pacific Premier acquisition’s broader product set is expected to enhance wallet share and support deeper relationships with customers.

Columbia Banking saw improvement in C&I production and pipelines in Q3 2025, indicating that the shift towards relationship banking is taking hold. Specialty hires and cross-line referrals are driving relationship growth post-Pacific Premier deal.

Relationship deposits are projected to lower funding costs and stabilize NIM as rates decline, targeting a 3.90% NIM in Q4 2025 and Q1 2026. Fee income growth from treasury management, commercial card, financial services, and trust is enhancing revenue quality.

COLB’s Zacks Rank #3 reflects stable earnings expectations as the bank executes on margin defense, fee income expansion, and loan-mix remix. Earnings trajectory is expected to improve into 2026 with integration benefits and mix shift maturing.

East West Bancorp (EWBC) and Western Alliance (WAL) are peers to watch in the industry, offering insights into C&I-anchored relationship growth and commercial franchises in growth markets.

A Zacks expert has identified a stock targeting millennial and Gen Z audiences with significant revenue potential. The recent pullback presents an ideal entry point for potential explosive upside, building on past Zacks’ Stocks Set to Double success stories.
