Columbia Banking (COLB) Q3 2026 Earnings Call Transcript

Columbia Banking System reported Q3 operating EPS of $0.82 and net interest margin of 4.11%, up 18 basis points sequentially; management guided to NIM of around 4.05% in Q4 and expects it to remain above 4% over the next several quarters. Customer deposits rose $1.2 billion to $52.7 billion, helping reduce wholesale funding by $1.5 billion, while nonperforming assets improved to 0.39% of total assets. The company repurchased 6.5 million shares for approximately $200 million and authorized a new $1.2 billion buyback plan; CET1 edged down to 11.5%, and tangible book value per share fell to $18.10 amid higher interest rates.

Analysis

The key distinction is between improving unit economics and a still-muted balance-sheet growth profile. The margin progress appears partly structural—better asset mix and less wholesale funding—but the quarter also benefited from accelerated loan repayments; management’s Q4 guide implies some giveback, while seasonal deposit outflows test whether low-cost funding gains are durable. With loans still running off, earnings growth increasingly depends on remixing, fee cross-sell, and repurchases rather than broad asset growth. That supports a constructive but not momentum-chasing view of COLB.

The new authorization is a potential per-share earnings tailwind, not a standalone valuation catalyst: continued repurchases alongside 11.5% CET1 and lower tangible book value make capital deployment and AOCI sensitivity worth monitoring. Meanwhile, passing on unusually aggressive CRE terms may suppress near-term production but could protect future credit costs if competition is weakening underwriting standards. The principal near-term catalyst is evidence that deposit retention and underlying NIM hold up through Q4 seasonality; over 6–18 months, the thesis requires relationship lending and fee growth to offset modest loan balances. Falsify it if core deposit costs rise materially, NIM falls below 4%, or credit migration/charge-offs worsen. Salesforce is mentioned only as a relationship-management tool; this call provides no distinct investment signal for CRM.

Key Decisions for Investors

• COLB: favor a small, staged long rather than chasing the post-earnings move; add only after Q4 results confirm NIM around guidance and core deposits remain stable. This is a 1–3 quarter execution thesis, not a call on rapid loan growth.
• For a market-neutral expression, pair a modest COLB long with a regional-bank ETF short (KRE) to reduce broad rate/sector exposure. Reassess if COLB’s relative performance weakens alongside deposit-cost pressure or credit deterioration.
• Monitor Q4 spot and average deposit costs, noninterest-bearing deposit mix, core loan production/payoffs, and credit migration. A sustained NIM below 4% or a meaningful rise in charge-offs would invalidate the constructive thesis; no separate CRM trade is indicated.
