INCOME STATEMENTS –Unaudited

[Footnotes to table located on page 6]

Net income for the first quarter of 2024 was $2.5 million, or $0.31 per diluted share, a $1.6 million decrease from the fourth quarter of 2023 and a $181 thousand decrease from the first quarter of 2023. Net interest income decreased $415 thousand during the first quarter of 2024, compared to the fourth quarter of 2023, and decreased $1.8 million, compared to the first quarter of 2023. The decrease in net interest income from the prior quarter was driven by less interest income on our federal funds sold and interest-bearing deposits, while the decrease from the prior year was driven by an increase in deposit and funding costs.

There was a reversal of the provision for credit losses of $175 thousand for the first quarter of 2024, compared to a reversal of $975 thousand during the fourth quarter of 2023 and a provision of $1.8 million during the first quarter of 2023. The provision reversal of $175 thousand during the first quarter of 2024 relates to a reversal in the reserve for unfunded commitments, driven by a decrease in the balance of unfunded commitments at March 31, 2024. As we continue to experience low net charge-offs, our expected loss rates continue to decline, resulting in a reduction in the allowance for credit losses as a percentage of total loans.

Noninterest income was $2.7 million for the first quarter of 2024, compared to $2.3 million for the fourth quarter of 2023, and $2.0 million for the first quarter of 2023. Mortgage banking income continues to be the largest component of our noninterest income at $1.2 million for the first quarter of 2024, $868 thousand for the fourth quarter of 2023, and $622 thousand for the first quarter of 2023.

Noninterest expense for the first quarter of 2024 was $18.1 million, a $1.1 million increase from the fourth quarter of 2023, and a $996 thousand increase from the first quarter of 2023. The increase in noninterest expense from the previous quarter was driven by an increase in compensation and benefits expense, while the increase from the prior year related not only to an increase in compensation and benefits expenses, but also to increases in outside service and data processing costs and insurance expenses. The increase in compensation and benefits expenses during the current quarter was due primarily to an increase in various benefit-related expenses. In addition, the increase in outside service and data processing costs from the prior quarter and prior year was driven by an increase in software licensing and maintenance costs, while insurance costs increased over the prior year due to higher FDIC insurance premiums.

Our effective tax rate was 25.5% for the first quarter of 2024, 21.9% for the fourth quarter of 2023, and 23.6% for the first quarter of 2023. The higher tax rate in the first quarter of 2024 as compared to the prior quarter and prior year was primarily related to the effect of equity compensation transactions during the quarter.

NET INTEREST INCOME AND MARGIN -Unaudited

[Footnotes to table located on page 6]

Net interest income was $18.6 million for the first quarter of 2024, a $415 thousand decrease from the fourth quarter of 2023, driven by a $772 thousand decrease in interest income, on a tax-equivalent basis, partially offset by a $357 thousand decrease in interest expense. The decrease in interest income was driven by a $107.5 million decrease in average federal funds sold and interest-bearing deposit balances. In comparison to the first quarter of 2023, net interest income decreased $1.8 million, resulting primarily from a $432.7 million increase in average interest-bearing liabilities during the 12 months ended March 31, 2024, combined with a 115-basis point increase in the average cost. Our net interest margin, on a tax-equivalent basis, was 1.94% for the first quarter of 2024, a two-basis point increase from 1.92% for the fourth quarter of 2023 and a 42-basis point decrease from 2.36% for the first quarter of 2023. During the first quarter of 2024, the yield on our loan portfolio increased by 10-basis points, while the cost of our interest-bearing deposits increased by only seven basis points, as compared to the fourth quarter of 2023, resulting in a slight increase in net interest margin for the period.

The lower net interest margin during the first quarter of 2024, as compared to the first quarter of 2023, was a result of our deposit and borrowing costs increasing faster than our loan yield as our interest-bearing liabilities have been more sensitive to changes in the federal funds rate over the past two years.

ASSET QUALITY MEASURES -Unaudited

Total nonperforming assets decreased by $317 thousand during the first quarter of 2024, and represented 0.09% of total assets, a decrease compared to 0.10% for the fourth quarter of 2023 and 0.12% for the first quarter of 2023. While we added three new relationships to nonaccrual during the first quarter of 2024, there were also three relationships either returned to accrual status or paid off during the quarter. In addition, our classified asset ratio decreased to 3.99% for the first quarter of 2024 from 4.25% in the fourth quarter of 2023 and from 5.10% in the first quarter of 2023.

At March 31, 2024, the allowance for credit losses was $40.4 million, or 1.11% of total loans, compared to $40.7 million, or 1.13% of total loans at December 31, 2023, and $40.4 million, or 1.18% of total loans, at March 31, 2023. We had net charge-offs of $241 thousand, or 0.03% annualized, for the first quarter of 2024, compared to net recoveries of $191 thousand for the fourth quarter of 2023 and net charge-offs of $59 thousand for the first quarter of 2023. There was no provision for credit losses recorded during the first quarter of 2024, compared to a reversal of $640 thousand for the fourth quarter of 2023 and a provision of $1.9 million for the first quarter of 2023. As we continue to experience low net charge-offs, the expected loss rates in our allowance for credit loss continue to decline, resulting in no provision for credit loss expense for the quarter.
