Quarterly Highlights

  • Net interest income for the third quarter of 2026 was $46.7 million, a $1.0 million, or 2.1%, decrease from the second quarter of 2026.

    • The decrease was primarily due to lower interest income on loans from a one-time $1.6 million interest income recovery on a nonaccrual loan resolution in the second quarter, less purchase accounting accretion, and higher interest expense, as average rates paid on deposits and borrowings increased slightly, mainly driven by the recent increase by the Federal Reserve in the federal funds benchmark rate. These factors were partially offset by higher loan and investment yields.

  • Net interest margin (on a tax-equivalent basis)(1) decreased 13 bps to 3.84%, from 3.97% for the second quarter of 2026.

    • The decrease was mainly attributable to a one-time $1.6 million interest income recovery on a nonaccrual loan resolution in the second quarter and less purchase accounting accretion, partially offset by higher loan and investment yields.

    • Net interest margin (on a tax-equivalent basis)(1) was impacted by 28 bps of purchase accounting accretion in the third quarter of 2026.

Year-Over-Year Highlights

  • Wealth Advisory Services revenue increased $1.4 million, or 22.0%, from the third quarter of 2025, driven by an increase in both asset-based fees and transaction-based fees.

  • Retirement and Benefit Services revenue increased $1.2 million, or 7.1%, compared to the third quarter of 2025, primarily driven by recurring annual income.

  • Adjusted banking fees & other income(1) increased $0.7 million, or 11.3%, from the third quarter of 2025, primarily driven by increases in swap fee income and deposit service charges, partially offset by a decrease in mortgage banking revenue driven by lower mortgage originations and gain on sale margins.

  • Retirement and Benefit Services revenue increased $0.3 million, or 1.8%, from the second quarter of 2026, primarily driven by an increase in recurring annual income.

  • Wealth Advisory Services revenue increased $0.3 million, or 3.8%, from the second quarter of 2026, primarily driven by an increase in transaction-based fees and a slight increase in asset-based revenues.

  • Adjusted banking fees & other income(1) decreased $0.1 million, or 1.5%, from the second quarter of 2026, primarily driven by a decrease in mutual fund investment gains related to the underlying assets of the deferred compensation plans; swap fee income also decreased on the quarter.

These decreases were partially offset by an increase in mortgage banking revenue driven by higher mortgage originations and gain on sale margins.

  • Net recoveries of $1.0 million in the third quarter of 2026 resulted in net recoveries to average loans(1) of 10 bps.

  • The quarter-over-quarter decrease in net charge-offs (recoveries) was primarily due to a $1.1 million recovery related to one long-term commercial and industrial client relationship on nonaccrual which was charged-off in the second quarter of 2026. As of September 30, 2026, the relationship had a remaining reserve of $0.9 million, which represented approximately 60.6% of the book balance as of that date.
