Net interest and dividend income expanded to $81.1 million from $62.9 million, helped by higher loan and securities income, partly offset by increased deposit and borrowing costs.
Credit costs rose meaningfully: the provision for credit losses climbed to $9.5 million from $2.4 million, and net charge-offs reached $10.8 million, driven by a large charge-off on a downtown Chicago office loan, a warehouse and distribution credit, and higher powersport loan losses. The allowance for credit losses on loans stood at $72.1 million. Total assets were $6.85 billion, with loans of $5.19 billion and deposits of $5.56 billion.
The company continued returning capital, declaring a quarterly dividend of $0.07 per share and repurchasing stock, which increased treasury stock to $26.2 million. After quarter-end, it redeemed $30.0 million of subordinated debt as it transitioned from a fixed to a SOFR-based floating rate.

Total loans were $5.19 billion, down $66.9 million, and total deposits were $5.56 billion.
Asset quality weakened as nonperforming assets rose to $77.0 million, influenced by a downtown Chicago office credit and a cash-flow-dependent commercial relationship, and the provision for credit losses increased to $9.5 million.
