Columbia Banking System, Inc. (NASDAQ: COLB) reported financial results for the fourth quarter and full year ended December 31, 2025. The regional bank posted solid quarterly revenue and earnings that exceeded analyst expectations and reflected the impact of its acquisition of Pacific Premier Bank. Full-year performance showed growth in key metrics compared with 2024, according to the company’s January 22, 2026 press release and earnings call.
Quarterly Financials
For the fourth quarter of 2025, Columbia Banking System reported net income of $215 million. Operating net income was $243 million. Earnings per diluted common share were $0.72 on a GAAP basis and $0.82 on an operating basis. Revenue for the period was approximately $717 million, up about 45% from the year-ago quarter and above consensus forecasts.
Non-interest income for the quarter increased compared with prior periods, while non-interest expense rose sequentially, reflecting operating costs tied to integration and broader scale. Pre-provision net revenue and operating pre-provision net revenue both showed sequential improvement. Dividends per share were increased to $0.37. Total assets at quarter-end stood near $66.8 billion.
Full year 2025 results, as reported in the company’s annual summary, showed revenue and earnings growth compared with 2024. Columbia Banking System noted a rise in both top-line revenue and net income for the full year.
Operational Update
Operational performance in Q4 was supported by growth in net interest income and an expansion of net interest margin, which improved from the prior quarter. The bank’s revenue mix continued to benefit from diversified income sources, including commercial lending, deposit products and fee income. Cost discipline efforts were in place amid integration of Pacific Premier’s operations. Management described performance as consistent and repeatable, reflecting disciplined expense control and balance sheet optimization.
Total assets increased significantly year-over-year, driven in part by the Pacific Premier acquisition, bringing greater scale and a larger deposit franchise across the western United States.
M&A
Columbia Banking System completed the acquisition of Pacific Premier Bancorp in the second half of 2025. The all-stock deal, initially announced in April 2025, closed on August 31, 2025, and brought Pacific Premier’s operations into Columbia’s footprint. This transaction expanded the bank’s presence in key Western U.S. markets, increased total assets and deposits, and contributed to revenue growth in the latter part of the year.
Post-acquisition integration activities continued through the quarter, including leadership transitions in finance functions to support the combined company’s financial reporting and strategic planning.
Market Risk Analysis and Outlook
Columbia Banking System’s outlook incorporates assessments of interest rate risk, credit quality and competitive pressures in the regional banking sector. Net interest margin expansion in Q4 reflected effective management of funding costs and earning asset yields. However, the banking sector continues to face a challenging environment marked by interest rate volatility and tightening credit conditions.
Credit quality metrics remained stable in the fourth quarter, with management highlighting disciplined underwriting and ongoing monitoring of asset performance. Integration-related expenses and macroeconomic uncertainty were noted as potential headwinds that could influence future quarters. Capital ratios and liquidity levels continued to meet regulatory well-capitalized thresholds, providing a buffer against market volatility.
The combination of scale from the Pacific Premier acquisition and continued focus on core deposit growth are expected to shape the company’s performance in 2026, although management emphasized that risks related to interest rates, economic growth and competitive dynamics in regional banking markets will influence execution. Columbia Banking System closed out 2025 with revenue and earnings above expectations. The quarter and year were marked by growth in net interest income, operational scale from the Pacific Premier acquisition and disciplined expense management. The company’s outlook reflects both opportunities from expanded market reach and risks from broader economic and interest rate conditions.
