Columbia Banking System's second quarter EPS met estimates, supported by merger cost savings and $199M in buybacks.

Columbia Banking System reported second quarter 2026 net interest income of $589 million and diluted EPS of $0.73. Total revenue of $677 million slightly missed analyst expectations, while earnings per share were in line with estimates.

Key Highlights

• Net interest margin (NIM) was 3.93%, a slight decrease of 3 basis points from the prior quarter, which the bank attributed entirely to $4 million in interest income reversals.
• The company realized significant cost savings from its Pacific Premier acquisition, with non-interest expense declining by $19 million sequentially to $375 million.
• Columbia returned a substantial amount of capital to shareholders, repurchasing $199 million of its common stock during the quarter.
