The increase in noninterest income for the three and six months ended June 30, 2026 was primarily due to an increase in insurance and wealth management services income, an increase in bank fees and service charges, and an increase in net gain on sale of loans, offset in part by a decrease in other noninterest income. The increase in insurance and wealth management services income was as a result of organic growth related to our wealth management services and the acquisition of Brown Financial Management Group during the three months ended December 31, 2025. The increase in bank fees and service charges and net gain on sale of loans was a result of the acquisition of Targeted Lending during the three months ended June 30, 2026.
