 as the spread between interest earned on assets and interest paid on liabilities. Net interest margin is defined as net interest income, on a taxable-equivalent basis, as a percentage of average earning assets.

The average balance of our earning assets for the three and nine months ended September 30, 2025 increased by $624.6 million or 3% and $452.4 million or 2%, respectively, compared to the same periods in 2024. These increases were due to increases in the average balances of available-for-sale investment securities and commercial mortgage loans. As compared to the same periods last year, yields on our investment securities portfolio increased by 13 and 9 basis points during the three

and nine months ended September 30, 2025, respectively, primarily due to the amortization of lower yielding investments being reinvested into new investments at higher current interest rates. This increase was partially offset by lower income earned from interest rate swaps that hedge a portion of our available-for-sale (“AFS”) securities portfolio. As compared to the same periods last year, yields on our loan and lease portfolio increased by 4 and 6 basis points during the three and nine months ended September 30, 2025, respectively, primarily due to higher rates on home equity lines and automobile loans originated, partially offset by the payoffs of higher yielding commercial mortgage and commercial and industrial loans.

The average balance of our interest-bearing liabilities for the three and nine months ended September 30, 2025 increased by $430.1 million or 3% and $342.7 million or 2%, respectively, compared to the same periods in 2024 primarily due to an increase in savings deposits. As compared to the same periods last year, the cost of our interest-bearing liabilities decreased by 37 and 30 basis points during the three and nine months ended September 30, 2025, respectively, primarily due to a decrease in the prevailing interest rate environment, which was driven by 125 basis points of interest rate cuts by the Federal Open Market Committee from September 2024 through September 2025.
