Columbia Banking System (COLB) Financials

Columbia Banking System (NASDAQ: COLB) showed a solid start to 2026, but the longer-term trend still points to a bank that is working through post-merger normalization, heavier balance-sheet costs, and some pressure on core profitability.

In Q1 2026, COLB generated $192 million in net income, or $0.66 per share, down from $215 million and $0.77 per share in Q4 2025. Revenue also slipped quarter over quarter to $677 million from $717 million. Even so, the bank remained profitable and produced strong operating cash flow of $494 million.

Over the past four years, the most important story has been the transformation of the balance sheet. Total assets rose from about $20.4 billion in Q3 2022 to $66.0 billion in Q1 2026, reflecting major growth and likely merger-related expansion. At the same time, equity has grown from roughly $2.1 billion in Q3 2022 to $7.7 billion in Q1 2026, though goodwill and intangible assets remain meaningful parts of the asset base.

• Operating cash flow was strong in Q1 2026, with $494 million from operations, showing the bank still converts earnings into cash effectively.
• Net interest income improved versus earlier periods, reaching $594 million in Q1 2026, above $505 million in Q3 2025 and $425 million in Q1 2025.
• Revenue held up well year over year, with Q1 2026 total revenue of $677 million above Q1 2025’s $491 million.
• Profitability remains intact, as COLB has posted positive net income in each quarter shown since mid-2023.
• Loan growth has been substantial over the multi-year period, with loans and leases rising to $47.7 billion in Q1 2026 from around $37.1 billion in Q1 2024.
• Deposit balances are large, but they have been volatile, which is normal for banks yet still worth watching for funding stability.
• The bank continues to carry significant goodwill and intangible assets, which can be a sensitivity if earnings weaken.
• Common share counts have generally been lower in recent quarters, supporting per-share earnings even when absolute profit growth is uneven.
• Quarterly EPS declined sequentially from $0.77 in Q4 2025 to $0.66 in Q1 2026.
• Non-interest expense remains elevated, at $394 million in Q1 2026, including a $24 million restructuring charge.

Margin pressure is still visible. In Q1 2026, interest income was $816 million, while interest expense was $222 million. That produced net interest income of $594 million, but funding costs remain significant. Deposit interest expense alone was $184 million in the quarter, so the bank’s profitability remains highly sensitive to deposit pricing and interest-rate changes.

Credit costs also deserve attention. Provision for credit losses was $28 million in Q1 2026, slightly above $23 million in Q4 2025 and below the much higher levels seen in some earlier periods. That suggests credit performance is manageable, but not fully free of pressure.

The quarter’s cash flow statement also showed an important theme: COLB used substantial financing activity to manage its balance sheet. It issued $3.4 billion of debt and repaid $3.2 billion, while deposits declined by $722 million. That kind of activity suggests active balance-sheet management, but it also highlights dependence on wholesale funding and deposit retention.

Bottom line: Columbia Banking System looks financially stable and still profitable, with strong cash generation and a much larger asset base than a few years ago. However, rising operating costs, a still-complex post-merger balance sheet, and quarter-to-quarter swings in earnings and deposits mean investors should expect steady execution rather than smooth, linear growth.
