STATEMENTS OF OPERATIONS HIGHLIGHTS

Net Interest Income

Net interest income for the third quarter of 2023 was $92.5 million, an increase of $16.3 million, or 21.4%, from the second quarter of 2023. The increase in net interest income was primarily due to an increase of $26.3 million in interest income and fees on loans and leases due to loans acquired and higher yields; partially offset by an increase of $12.4 million in deposit interest expense due to deposits assumed and higher rates on deposits.

Tax-equivalent net interest margin1 for the third quarter of 2023 was 4.47%, an increase of 14 basis points compared to the second quarter of 2023. Total net loan accretion income impact on the margin contributed 50 basis points to the net interest margin for the third quarter of 2023 compared to three basis points for the second quarter of 2023.

The average cost of total deposits was 2.13% for the third quarter of 2023, an increase of 43 basis points compared to the second quarter of 2023, as a result of higher rates on money market accounts and time deposits. Average non-interest-bearing demand deposits were 28.8% of average total deposits for the third quarter of 2023 compared to 31.7% during the second quarter of 2023.

Provision for Credit Losses

The provision for credit losses was $8.8 million for the third quarter of 2023, an increase of $3.0 million compared to $5.8 million for the second quarter of 2023, mainly attributed to a $2.7 million provision allocated for acquired non-credit-deteriorated loans resulting from acquisition accounting. The provision for credit losses is comprised of a provision for loan and lease losses of $7.9 million and a provision for unfunded commitments of $938,000.

Non-interest Income

Non-interest income for the third quarter of 2023 was $12.4 million, a decrease of $1.9 million, or 13.4%, compared to $14.3 million for the second quarter of 2023. The decrease in total non-interest income was primarily due to a decrease of $2.8 million in the valuation of the loan servicing asset reflecting higher discount rates and higher prepayment rates, partially offset by an increase of $769,000, or 13.5%, in the net gain on sales of loans. During the third quarter of 2023, we sold $101.6 million of U.S. government guaranteed loans compared to $85.9 million during the second quarter of 2023.

Non-interest Expense

Non-interest expense for the third quarter of 2023 was $57.9 million, an increase of $8.6 million, or 17.4%, from $49.3 million for the second quarter of 2023. The increase in total non-interest expense was mainly due to an increase of $5.3 million in salaries and employee benefits and an increase of $2.2 million in data processing, both primarily driven by merger-related expenses.

Our efficiency ratio was 53.75% for the third quarter of 2023 compared to 52.92% for the second quarter of 2023. Excluding significant items, our adjusted efficiency ratio1 for the third quarter 2023 was 47.35%, compared to 51.39% for the second quarter of 2023.

Income Taxes

We recorded income tax expense of $9.9 million during the third quarter of 2023, compared to $9.2 million during the second quarter of 2023. The effective tax rate was 26.0% and 26.1% for the third quarter of 2023 and second quarter of 2023, respectively.

STATEMENTS OF FINANCIAL CONDITION HIGHLIGHTS

Assets

Total assets were $8.9 billion as of September 30, 2023, an increase of $1.4 billion, or 18.1%, compared to $7.6 billion at June 30, 2023.

The current quarter increase was primarily due to an increase in net loans and leases of $1.0 billion mainly due to the acquisition; an increase in securities available-for-sale of $114.2 million, driven by increases in acquired securities; and an increase in cash and cash equivalents of $108.7 million mainly to support loan and lease portfolio growth and customer-related activities.

Non-performing loans and leases were $52.1 million at September 30, 2023, an increase of $13.8 million from $38.3 million at June 30, 2023. The increase was primarily the result of $13.7 million of non-performing acquired purchased credit deteriorated (PCD) loans.

Allowance for Credit Losses ("ACL") - Loans and Leases

ACL was $105.7 million as of September 30, 2023, an increase of $13.0 million, or 14.1%, from $92.7 million at June 30, 2023. The increase includes $10.6 million for PCD loans and a $2.7 million provision for acquired non-credit-deteriorated loans, as a result of the recent acquisition. Additional provision for originated loans and leases and an increase in individually assessed impairments were reduced by net charge-offs.

Net charge-offs of loans and leases during the third quarter of 2023 were $5.4 million, or 0.33% of average loans and leases, on an annualized basis. This was an increase of $1.1 million compared to net charge-offs of $4.3 million, or 0.31% of average loans and leases, during the second quarter of 2023.

Deposits and Other Liabilities

Total deposits increased to $7.0 billion at September 30, 2023 compared to $5.9 billion at June 30, 2023. Non-interest-bearing deposits were 28.2% and 30.3% of total deposits at September 30, 2023 and June 30, 2023, respectively. Estimated total uninsured deposits were $1.8 billion and $1.5 billion as of September 30, 2023 and June 30, 2023, and represented 26.1% and 25.9% of total deposits, respectively. The increase in deposits in the current quarter was mainly due to the deposits assumed and increased deposit campaigns. The increase in time deposits of $327.9 million was principally due to increased personal time deposits. The increase in money market demand accounts of $462.2 million was due to increases in consumer and commercial deposits. The increase in non-interest-bearing demand deposits of $166.1 million was mainly due to increases in assumed commercial deposits.

Total borrowings and other liabilities were $1.1 billion at September 30, 2023, an increase of $225.1 million from $844.7 million at June 30, 2023, primarily driven by increases in Federal Home Loan Bank advances, assumed junior subordinated debentures, accrued expenses and other liabilities.

Stockholders’ Equity

Total stockholders’ equity was $919.9 million at September 30, 2023, an increase of $106.0 million from $813.9 million at June 30, 2023. The increase was primarily due to stock consideration issued in connection with the acquisition.
