Cost of other long-term borrowings decreased 259 basis points to 5.82% in the fourth quarter of 2025, compared to the prior quarter, primarily due to the redemption of $40.0 million of subordinated notes.

Asset Quality and Provision for Credit Losses

The provision for credit losses totaled $6.2 million for the fourth quarter of 2025 primarily due to impacts from net portfolio downgrades.

Net charge-offs for the fourth quarter of 2025 were $5.0 million resulting in an annualized ratio of net charge-offs to average loans of 0.30%, compared to net charge-offs of $9.1 million, or an annualized ratio of net-charge offs to average loans of 0.55% for the prior quarter. Net charge-offs for the fourth quarter of 2025 were elevated primarily due to a write-down related to a specific customer relationship in our C&I loan portfolio.

Asset Quality and Provision for Credit Losses

The provision for credit losses totaled $24.6 million in 2025, a decrease of $3.0 million compared to 2024.

Treasury management service fees increased $2.6 million in 2025 compared to 2024, primarily due to growth in services provided to our business customers. Other noninterest income increased $2.8 million in 2025 compared to 2024, primarily due to an increase in loan syndication fees and swap fee income.
