Columbia Banking System (COLB) Q4 2023 earnings summary

Executive summary

• Q4 net income was $93.5 million, or $0.45 diluted EPS; operating net income was $91.5 million, or $0.44 operating diluted EPS, including a $33 million FDIC special assessment.

• Net interest margin fell 13 bps QoQ to 3.78% as higher deposit costs outweighed improved earning-asset yields and mix.

• Merger integration was largely complete; annualized cost savings reached $143 million at year-end, above the original $135 million target.

• Comparisons with periods before the February 28, 2023 merger may not be directly comparable; pre-close periods reflect standalone Umpqua results.

Financial highlights

• Net interest income was $453.6 million, down $27 million QoQ; non-interest income rose $22 million to $66 million, primarily from favorable fair-value adjustments and MSR hedging.

• Non-interest expense increased $33 million QoQ to $337.2 million, including the $33 million FDIC assessment; merger-related expense declined $12 million to $7 million.

• Loans grew $271 million QoQ, or 3% annualized; deposits were $41.6 billion, relatively unchanged as public-fund growth offset customer cash use.

• Q4 provision for credit losses was $54.9 million; net charge-offs were $28.9 million, or 0.31% of average loans annualized, versus 0.25% in Q3.

• FY2023 net income was $349 million and diluted EPS was $1.78; merger timing limits direct comparisons with prior reported periods.

Outlook and guidance

• FY2024 average earning assets: $48–$49 billion; GAAP NIM: 3.50%–3.60%; outlook assumes three Federal Reserve rate cuts in late 2024.

• FY2024 purchase-accounting accretion outlook: securities rate-related $130–$140 million; loans rate-related $90–$100 million; loans credit-related $15–$20 million.

• FY2024 adjusted non-interest expense outlook: $1.0–$1.1 billion, excluding CDI amortization and merger expense; CDI amortization ~ $120 million and merger-related expense $10–$15 million.

• Guidance assumes 0%–3% balance-sheet growth; deposit stability supports the upper end of the NIM range, while deposit contraction and continued remixing inform the lower end.

• With integration largely complete, focus shifts to performance optimization and shareholder value, balancing efficiency opportunities against franchise-development investments.
