STATEMENTS OF OPERATIONS HIGHLIGHTS

Net Interest Income

Net interest income for the first quarter of 2025 was $88.2 million, a decrease of $308,000, or 0.3%, from the fourth quarter of 2024. The decrease in net interest income was primarily due to lower interest income due to declining loan yields and two less calendar days, offset by lower interest expense mainly due to lower rates paid on interest-bearing deposits.

Tax-equivalent net interest margin(1) for the first quarter of 2025 was 4.08%, an increase of six basis points compared to the fourth quarter of 2024. Net loan accretion income positively contributed 12 basis points to the net interest margin for both the current and prior quarter.

The average cost of total deposits was 2.30% for the first quarter of 2025, a decrease of 18 basis points compared to the fourth quarter of 2024, mainly as a result of lower rates paid on deposits and a shift in the deposit mix. Average non-interest-bearing demand deposits were 23.4% of average total deposits for the current quarter compared to 23.8% during the prior quarter.

Provision for Credit Losses

The provision for credit losses was $9.2 million for the first quarter of 2025, an increase of $2.3 million compared to $6.9 million for the fourth quarter of 2024, mainly attributed to a larger allowance for government guaranteed collectively assessed loans based on changes in loss rates.

Non-interest Income

Non-interest income for the first quarter of 2025 was $14.9 million, a decrease of $1.3 million, or 8.0%, compared to $16.1 million for the fourth quarter of 2024. The decrease in total non-interest income was primarily due to a decrease in net gains on sales of loans, driven by lower volume and guaranteed balances. Net gains on sales of loans were $4.9 million for the current quarter, a decrease of $2.2 million, or 30.5% compared to the prior quarter. During the first quarter of 2025, we sold $70.2 million of U.S. government guaranteed loans compared to $88.9 million during the fourth quarter of 2024.

Non-interest Expense

Non-interest expense for the first quarter of 2025 was $56.4 million, a decrease of $1.0 million, or 1.7%, compared to $57.4 million for the fourth quarter of 2024. The decrease in non-interest expense was mainly due to a $1.0 million decrease in salaries and employee benefits resulting from a lower day count and lower incentive compensation, a $612,000 decrease in net loss recognized on other real estate owned and other related expenses mainly due to lower real estate taxes, and a $337,000 decrease in other non-interest expenses mainly due to a $946,000 decrease in advertising and promotion expense and decreases in other general expenses, offset by a $767,000 lower gain on sales of leased assets. These decreases were offset by an increase to data processing of $698,000 mainly due to merger-related data processing expenses.

Our efficiency ratio was 53.66%(1) for the first quarter of 2025, compared to 53.58% for the fourth quarter of 2024, an increase of 8 basis points. Our adjusted efficiency ratio was 53.04%(1) for the first quarter of 2025, compared to 53.37%(1) for the fourth quarter of 2024, a decrease of 33 basis points.

Income Taxes

We recorded income tax expense of $9.2 million during the first quarter of 2025, compared to $10.0 million during the fourth quarter of 2024. The effective tax rates were 24.6% and 24.9% for the first quarter of 2025 and fourth quarter of 2024, respectively.

STATEMENTS OF FINANCIAL CONDITION HIGHLIGHTS

Assets

Total assets were $9.6 billion as of March 31, 2025, an increase of $88.2 million, or 0.9%, compared to $9.5 billion at December 31, 2024. The increase for the current quarter was mainly due to an increase in securities available-for-sale of $122.4 million primarily from purchases and an increase in net loans and leases of $116.6 million driven by increases to the commercial and industrial loan portfolio. These were offset by a decrease in cash and cash equivalents of $141.8 million, due to purchases of securities and lower balances held with the Federal Reserve Bank.

Asset and Credit Quality

The ACL was $100.4 million as of March 31, 2025, an increase of $2.4 million, or 2.5%, from $98.0 million at December 31, 2024, mainly due to growth in the loan and lease portfolio and higher allowance on commercial and industrial loans. Net charge-offs of loans and leases during the first quarter of 2025 were $6.6 million, or 0.39% of average loans and leases, on an annualized basis. This was a decrease of $1.1 million compared to net charge-offs of $7.8 million, or 0.45% of average loans and leases, during the fourth quarter of 2024. The decrease in charge-offs for the quarter was primarily in the government guaranteed loan portfolio.

Non-performing assets were $59.9 million, or 0.62% of total assets, as of March 31, 2025, a decrease of $7.4 million from $67.2 million, or 0.71% of total assets, at December 31, 2024. The decrease was primarily due to charge-off and resolution of non-performing assets. The government guaranteed portion of non-performing loans included in non-performing assets was $9.4 million at March 31, 2025, compared to $9.9 million at December 31, 2024, a decrease of $438,000.

Deposits and Other Liabilities

Total deposits increased $94.7 million to $7.6 billion at March 31, 2025 compared to $7.5 billion at December 31, 2024. The increase in deposits in the current quarter was mainly due to increases in money market accounts and interest-bearing business checking accounts, both due to deposit shift and new depositors, offset by decreases to time deposits mainly due to decreased brokered time deposits.

Total borrowings and other liabilities were $900.3 million at March 31, 2025, a decrease of $46.1 million from $946.4 million at December 31, 2024. The decrease was primarily driven by decreased Federal Home Loan Bank advances.

Stockholders’ Equity

Total stockholders’ equity was $1.1 billion at March 31, 2025, an increase of $39.6 million, or 3.6%, from December 31, 2024, primarily due to an increase to retained earnings from net income and a decrease in accumulated other comprehensive loss due to a decrease in the unrealized losses on securities available-for-sale. During the first quarter of 2025, we purchased 26,000 shares of our common stock under our share repurchase plan, at an average price of $26.41 per share.
