Total shareholders’ equity was $314.3 million at June 30, 2025.

Selected highlights at and for the three and six months ended June 30, 2025 are as follows:

Net Interest Income and Margin

Net interest income increased $2.4 million, or 14.0%, to $19.6 million for the three months ended June 30, 2025 from $17.2 million for the three months ended June 30, 2024, and increased $4.2 million, or 12.1%, to $38.7 million for the six months ended June 30, 2025 from $34.5 million for the six months ended June 30, 2024. The increase in net interest income for the three months ended June 30, 2025 was primarily due to an increase in the average yield on interest-earning assets of 31 basis points and an increase in the average balance of interest-earning assets of $144.9 million, partially offset by an increase in the average cost of interest-bearing liabilities of 14 basis points and an increase in the average balance of interest-bearing liabilities of $105.4 million. The increase in net interest income for the six months ended June 30, 2025 was primarily due to an increase in the average yield on interest-earning assets of 32 basis points and an increase in the average balance of interest-earning assets of $126.5 million, partially offset by an increase in the average cost of interest-bearing liabilities of 17 basis points and an increase in the average balance of interest-bearing liabilities of $96.4 million.

Interest income increased $3.4 million, or 14.6%, to $27.0 million for the three months ended June 30, 2025, from $23.6 million for the three months ended June 30, 2024. Interest income increased $6.2 million, or 13.2%, to $52.9 million for the six months ended June 30, 2025, from $46.7 million for the six months ended June 30, 2024. The increase in interest income for the three and six months ended June 30, 2025 was driven by market-related increases in interest rates on new loans and on investment securities purchased. The average yield on interest-earning assets increased by 31 basis points to 5.72% for the three months ended June 30, 2025, compared to 5.41% for the three months ended June 30, 2024.  The average yield on interest-earning assets increased by 32 basis points to 5.63% for the six months ended June 30, 2025, compared to 5.31% for the six months ended June 30, 2024.  

Interest expense increased $1.0 million, or 16.3%, to $7.4 million for the three months ended June 30, 2025 from $6.4 million for the three months ended June 30, 2024. Interest expense increased $2.1 million, or 16.6%, to $14.2 million for the six months ended June 30, 2025 from $12.1 million for the six months ended June 30, 2024. The average cost of interest-bearing liabilities increased by 14 basis points to 2.41% for the three months ended June 30, 2025, compared to 2.27% for the three months ended June 30, 2024. The average cost of interest-bearing liabilities increased by 17 basis points to 2.35% for the six months ended June 30, 2025, compared to 2.18% for the six months ended June 30, 2024. The average cost of interest-bearing liabilities increased for the three and six months ended June 30, 2025 primarily due to the repricing of certain interest-bearing deposit accounts in response to changes in market interest rates and the higher interest rate environment, as well as a shift in the mix of deposits towards higher cost interest-bearing accounts.

Net interest margin increased 20 basis points to 4.13% for the three months ended June 30, 2025, compared to 3.93% for the three months ended June 30, 2024. Net interest margin increased 21 basis points to 4.12% for the six months ended June 30, 2025, compared to 3.91% for the six months ended June 30, 2024.

Asset Quality and Provision for Credit Losses

Non-performing assets were $11.5 million, or 0.55% of total assets, at June 30, 2025, compared to $5.2 million, or 0.27% of total assets, at December 31, 2024. The increase in non-performing assets at June 30, 2025 was primarily due to a $4.7 million commercial real estate loan relationship consisting of four loans secured by multiple office, warehouse and industrial properties being placed on non-accrual status during the six months ended June 30, 2025.

The allowance for credit losses on loans was $23.8 million at June 30, 2025, compared to $21.8 million at December 31, 2024, representing 1.52% and 1.49% of total loans outstanding, respectively.

Net charge-offs were $70,000 and $85,000 for the three and six months ended June 30, 2025, respectively, compared to net charge-offs of $129,000 and $149,000 for the three and six months ended June 30, 2024, respectively. Annualized net charge-offs were 0.02% and 0.01% of average loans for the three and six months ended June 30, 2025, respectively, compared to annualized net charge-offs of 0.04% and 0.02% of average loans for the three and six months ended June 30, 2024, respectively.

The provision for credit losses was $1.6 million and $2.4 million for the three and six months ended June 30, 2025, respectively, as compared to a provision for credit losses of $750,000 and $830,000 for the three and six months ended June 30, 2024, respectively. The increase in the provision for credit losses for the three and six months ended June 30, 2025 was primarily due to growth in the loan portfolio and changes in current economic conditions.

Noninterest Income and Noninterest Expense

Noninterest income of $4.8 million for the three months ended June 30, 2025 increased $1.1 million, or 30.3%, as compared to $3.7 million for the three months ended June 30, 2024. Noninterest income of $8.5 million for the six months ended June 30, 2025 increased $609,000, or 7.7%, as compared to $7.9 million for the six months ended June 30, 2024. The increase in noninterest income for the three months ended June 30, 2025 was primarily due to a $706,000 increase in other noninterest income and a $235,000 increase in insurance and wealth management services income. The increase in noninterest income for the six months ended June 30, 2025 was primarily due to a $692,000 increase in other noninterest income and a $263,000 increase in insurance and wealth management services income, offset in part by $386,000 of net gain on equity securities during the six months ended June 30, 2024 as compared to no such gain for the six months ended June 30, 2025. The increase in other noninterest income for the three and the six months ended June 30, 2025 was primarily due to $550,000 of bank-owned life insurance income as a result of a death benefit. The increase in insurance and wealth management services income for the three and the six months ended June 30, 2025 was primarily as a result of organic growth and positive market performance related to our wealth management services.

Noninterest expense of $14.7 million for the three months ended June 30, 2025 decreased $379,000, or 2.5%, as compared to $15.1 million for the three months ended June 30, 2024. Noninterest expense of $29.3 million for the six months ended June 30, 2025 decreased $1.2 million, or 4.0%, as compared to $30.5 million for the six months ended June 30, 2024. The decrease in noninterest expense for the three months ended June 30, 2025 was primarily due to a decrease in professional fees of $693,000 and a decrease in other expenses of $718,000, offset in part by an increase in salaries and employee benefits of $1.0 million. The decrease in noninterest expense for the six months ended June 30, 2025 was primarily due to a decrease in professional fees of $1.9 million and a decrease in other expenses of $1.2 million, offset in part by an increase in salaries and employee benefits of $2.0 million. Professional fees decreased due to lower legal fees and expenses as compared to the prior-year periods. Other expenses decreased due to a benefit for the other cost components of the net periodic pension and post-retirement benefits cost during the three and six months ended June 30, 2025. Salaries and employee benefits increased due to compensation expense from annual merit increases as well as due to share-based compensation costs recognized during the three and six months ended June 30, 2025 for the stock awards granted during the three months ended June 30, 2024.

Income Taxes

Income tax expense increased $586,000 to $1.7 million for the three months ended June 30, 2025 as compared to $1.1 million for the three months ended June 30, 2024 primarily due to an increase in income before income taxes. Income tax expense increased $903,000 to $3.3 million for the six months ended June 30, 2025 as compared to $2.4 million for the six months ended June 30, 2024 primarily due to an increase in income before income taxes. Our effective tax rate was 20.7% and 21.5% for the three and six months ended June 30, 2025, respectively, compared to 21.9% and 22.0% for the three and six months ended June 30, 2024, respectively. The decrease in the effective tax rate for the three and the six months ended June 30, 2025 was due to bank-owned life insurance income which is exempt from income tax expense as a result of a death benefit recognized during the three and six months ended June 30, 2025.
