INCOME STATEMENT HIGHLIGHTS

Net Interest Income

Net interest income was $110.8 million for the second quarter of 2024. This represented a $1.6 million, or 1.43%, decline from the first quarter of 2024, and an $8.7 million, or 7.27%, decrease from the second quarter of 2023. The quarter-over-quarter decrease in net interest income was due to a five basis point decline in net interest margin. The decline in net interest income compared to the second quarter of 2023 was due to a 17 basis point decrease in net interest margin and a $294.2 million decline in average earning assets.

Net Interest Margin

Our tax equivalent net interest margin was 3.05% for the second quarter of 2024, compared to 3.10% for the first quarter of 2024 and 3.22% for the second quarter of 2023. The five basis point decrease in our net interest margin compared to the first quarter of 2024, was the result of a seven basis point increase in our cost of funds, offset by a three basis point increase in our interest-earning asset yield. The three basis point increase in our interest-earning asset yield was due to the net impact of a seven basis point increase in the yield on investment securities, an increase in funds held at the Federal Reserve and a four basis point decrease in loan yields. The increase in investment yields was primarily due to the increased spread on pay-fixed swaps. The mix of earning assets was positively impacted by the increase in average funds held at the Federal Reserve, yielding 5.4%, which increased from 3% of earning assets in the prior quarter to nearly 5% in the second quarter of 2024. Our cost of funds increased in the second quarter to 1.38%, as our cost of deposits and customer repurchase agreements increased by 14 basis points to 0.87%. Non-maturity interest-bearing deposits also increased in cost from the prior quarter by 14 basis points, while time deposits increased on average by $286 million, with an increase to the cost of time deposits of 79 basis points. On average, borrowings decreased by $142 million compared to the first quarter, while continuing to have an average cost of 4.76%. The decrease in net interest margin of 17 basis points, compared to the second quarter of 2023, was primarily the result of a 55 basis point increase in cost of funds. This increase in cost of funds from the prior year was the result of a 53 basis point increase in the cost of deposits and an increase in the level of borrowings, which grew on average by $323 million. A 36 basis point increase in earning asset yields over the prior year quarter partially offset the increase in funding costs. Included in the higher earning asset yields, were higher loan yields, which grew from 5.01% for the second quarter of 2023 to 5.26% for the second quarter of 2024. Additionally, the yield on investment securities increased by 34 basis points from the prior year quarter, primarily due to the positive spread generated from the Company’s pay-fixed swaps, in which the Company receives daily SOFR and pays a weighted average fixed cost of approximately 3.8%.

Earning Assets and Deposits

On average, total earning assets were stable between the first and second quarter of 2024 but declined by $294.2 million when compared to the second quarter of 2023. Compared to the second quarter of 2023, the mix of assets changed modestly, with the average balance of investment securities decreasing by $482.6 million and declining from 38% to 35.5% of total earning assets. Conversely, the average amount of funds held at the Federal Reserve increased by $356.9 million, growing from 2.4% of total earning assets in the second quarter of 2023 to 4.9% for the second quarter of 2024. Noninterest-bearing deposits declined on average by $29.4 million, or 0.41%, from the first quarter of 2024 and interest-bearing deposits and customer repurchase agreements increased on average by $252.6 million, including an increase in average time deposits of $285.8 million. Compared to the second quarter of 2023, total deposits and customer repurchase agreements declined on average by $631.1 million, or 4.93%, including a decline of $670 million in noninterest-bearing deposits. Non-maturity interest-bearing deposits and customer repurchase agreements decreased by $398.5 million on average, while time deposits grew on average by $437.5 million. On average, noninterest-bearing deposits were 60.20% of total deposits during the most recent quarter, compared to 61.72% for the first quarter of 2024 and 63.58% for the second quarter of 2023.

Provision for Credit Losses

There was no provision for credit losses in the first and second quarter of 2024, compared to $500,000 in provision in the second quarter of 2023. Net charge-offs for the second quarter of 2024 were $31,000, compared to $4.0 million in the prior quarter. Projected loss rates were 0.95% at June 30, 2024, compared to 0.94% at March 31, 2024.

Noninterest Income

Noninterest income was $14.4 million for the second quarter of 2024, compared with $14.1 million for the first quarter of 2024 and $12.7 million for the second quarter of 2023. Second quarter income from Bank Owned Life Insurance (“BOLI”) decreased by $651,000 from the first quarter of 2024 and increased by $845,000 compared to the second quarter of 2023. We experienced $531,000 in death benefits that exceeded the asset value on certain policies in the first quarter of 2024 and approximately $800,000 in death benefits in the second quarter of 2023. There were no death benefits in the second quarter of 2024. As a result of the restructuring and enhancements in BOLI policies during the fourth quarter of 2023, the income derived from increases in the cash-surrender value of the policies was $1.6 million higher in the second quarter of 2024, when compared to the year-ago quarter.

Noninterest Expense

Noninterest expense for the second quarter of 2024 was $56.5 million, compared to $59.8 million for the first quarter of 2024 and $54.0 million for the second quarter of 2023. The $3.3 million quarter-over-quarter decrease was primarily due to the $3.0 million expense variance resulting from changes in the amount accrued as an estimate of the FDIC special assessment. In the first quarter of 2024, the FDIC revised and increased their initial loss estimate described in their final rule to implement a special assessment to recover the loss to the Deposit Insurance Fund (DIF) associated with protecting uninsured depositors following the closures of Silicon Valley Bank

- 3 -

and Signature Bank by 25%, which resulted in the Company recording an additional $2.3 million for the FDIC special assessment in the first quarter. In the second quarter of 2024, the loss estimate was revised and reduced to reflect the initial amount assessed by the FDIC, resulting in a $700,000 reduction in this accrual. There was a $500,000 recapture of provision for unfunded loan commitments in the second quarter of 2024, compared to no provision or recapture in the first quarter of 2024. The $975,000 quarter-over-quarter decrease in staff related expenses included $1.5 million in lower payroll taxes, due to the timing of related payroll taxes, including the impact from the payment of bonuses in the first quarter of 2024. Software expense increased by $424,000 or 12% compared to the prior quarter. Marketing and promotion expense increased by $326,000 due to higher donations of $587,000 in the second quarter and professional services increased $471,000, including a $285,000 increase in legal expense, quarter-over-quarter.

The $2.5 million increase in noninterest expense year-over-year included increased staff related expenses of $1.9 million, or 5.60%. Marketing and promotion expense increased by $635,000 due to $673,000 in higher donations in the second quarter of 2024 and software expense increased $633,000, or 19% year-over-year. As a percentage of average assets, noninterest expense was 1.40% for the second quarter of 2024, compared to 1.48% for the first quarter of 2024 and 1.32% for the second quarter of 2023. The efficiency ratio for the second quarter of 2024 was 45.10%, compared to 47.22% for the first quarter of 2024 and 40.86% for the second quarter of 2023.

Income Taxes

Our effective tax rate for the quarter ended June 30, 2024 was 27.25%, compared with 28.20% for the same period of 2023. Our estimated annual effective tax rate can vary depending upon the level of tax-advantaged income from municipal securities and BOLI, as well as available tax credits.

BALANCE SHEET HIGHIGHTS

The increase in assets included a $559.9 million increase in interest-earning balances due from the Federal Reserve, offset by a $245.1 million decrease in investment securities, and a $219.0 million decrease in net loans.

Total assets at June 30, 2024 decreased by $333.0 million, or 2.02%, from total assets of $16.48 billion at June 30, 2023. The decrease in assets was primarily due to a $405.2 million decrease in investment securities and a $221.4 million decrease in net loans, partially offset by an increase of $282.7 million in interest-earning balances due from the Federal Reserve and a $57.0 million increase in the cash surrender value of BOLI.

Investment Securities and BOLI

Total investment securities were $5.18 billion at June 30, 2024, a decrease of $245.1 million, or 4.52% from December 31, 2023, and a decrease of $405.2 million, or 7.26%, from $5.58 billion at June 30, 2023.

This restructuring has increased returns on our BOLI policies resulting in additional non-taxable noninterest income in 2024.
