Net interest income increased 8.3% from the same quarter of 2024. The growth in core deposits has allowed us to reduce borrowings by $245 million, or 64%, in 2025 year to date, which further strengthened our net interest margin in the quarter."

Loans receivable decreased $5.7 million, or 0.1%, during the third quarter of 2025 due primarily to an elevated level of prepaid and closed loans, offset partially by new loan production for the quarter.

Loan payoffs increased to $55.8 million, compared to $51.0 million in the prior quarter.

Commercial and industrial loans decreased $12.0 million, or 1.4%, during the third quarter of 2025, due primarily to pay downs on outstanding balances, partially offset by new loan production of $65.6 million. Owner-occupied commercial real estate ("CRE") loans increased $7.8 million, or 0.8%, during the third quarter of 2025, due primarily to new loan production of $24.8 million, partially offset by pay downs on outstanding balances.

Residential real estate loans decreased by $9.1 million, or 2.4%, during the quarter due to loan payoffs. Residential construction loans increased by $12.4 million, or 15.8% during the quarter due primarily to new loan production.

Total deposits increased $73.1 million, or 1.3%, to $5.86 billion at September 30, 2025 from $5.78 billion at June 30, 2025. Non-maturity deposits increased by $104.5 million, or 2.2%, from June 30, 2025 due primarily to an increase in customer balances in noninterest bearing demand and interest bearing demand accounts. The increase in non-maturity deposits was partially offset by a decrease of $31.4 million in certificates of deposit accounts. The decline in certificates of deposit accounts was due primarily to the maturity of $25.1 million of brokered certificates of deposit.

The following table summarizes the Company's total deposits at the dates indicated:

Total stockholders' equity increased $15.9 million, or 1.8%, to $904.1 million at September 30, 2025 compared to $888.2 million at June 30, 2025 due primarily to $19.2 million of net income recognized for the quarter and a $3.7 million decrease in accumulated other comprehensive loss. These increases were partially offset by $8.3 million in dividends paid to common shareholders during the quarter.

Allowance for Credit Losses and Provision for Credit Losses

The allowance for credit losses ("ACL") on loans as a percentage of loans receivable was 1.13% at September 30, 2025 compared to 1.10% at June 30, 2025. The increase in the ACL as a percentage of loans was due primarily to changes in the weighted average life of loans in the real estate construction and land development segment. During the third quarter of 2025, the Company recorded a $1.6 million provision for credit losses on loans, compared to a $0.9 million provision during the second quarter of 2025.

During the third quarter of 2025, the Company recorded a $212,000 provision for credit losses on unfunded commitments compared to a $93,000 provision during the second quarter of 2025. The provision for credit losses on unfunded commitments during the third quarter of 2025 was due primarily to an increase in the unfunded exposure on construction loans.

The following table provides detail on the changes in the ACL on loans and the ACL on unfunded commitments, and the related provision for (reversal of) credit losses for the periods indicated:

Net Interest Margin and Net Interest Income

Net interest margin increased 13 basis points to 3.64% during the third quarter of 2025 from 3.51% during the second quarter of 2025.

The yield on interest earning assets increased three basis points to 5.04% for the third quarter of 2025 compared to 5.01% for the second quarter of 2025. The yield on loans receivable increased three basis points to 5.53% during the third quarter of 2025, compared to 5.50% during the second quarter of 2025 as new loans were booked and adjustable rate loans repriced at higher rates.

The cost of interest bearing deposits decreased five basis points to 1.89% for the third quarter of 2025 from 1.94% for the second quarter of 2025. This decrease was primarily due to a decrease in certificate of deposit rates.

Net interest income increased $2.4 million, or 4.3%, during the third quarter of 2025 compared to the second quarter of 2025 due to a $1.0 million increase in total interest income and a decrease in interest expense of $1.4 million.

Net interest margin increased 34 basis points to 3.64% from 3.30% compared to the same period in the prior year. Net interest income increased $4.4 million, or 8.3%, during the third quarter of 2025 compared to the third quarter of 2024. The increase was due primarily to a change in the mix of earning assets to higher yielding loan balances and a decrease in deposit and borrowing interest expense due to lower rates.

Noninterest Income

Noninterest income increased $6.8 million to $8.3 million during the third quarter of 2025 from $1.5 million during the second quarter of 2025. The increase was due primarily to a $6.9 million loss recognized in the second quarter of 2025 resulting from the sale of investment securities as part of the Company's strategic repositioning of its balance sheet. The increase was partially offset by a decrease in bank owned life insurance ("BOLI") income due to nonrecurring death benefit proceeds received in the second quarter of 2025.

Noninterest income increased $6.5 million from the same period in 2024 due primarily to a $6.9 million loss recognized in the third quarter of 2024 resulting from the sale of investment securities as part of the above-mentioned strategic repositioning of the Company's balance sheet. The decrease was partially offset by an increase in gain on sale of other assets, net which was due to the $1.5 million gain on sale of an administrative building recognized during the third quarter of 2024.

The following table presents the key components of noninterest income and the change for the periods indicated:

Noninterest Expense

Noninterest expense increased $0.5 million, or 1.3%, to $41.6 million during the third quarter of 2025, compared to $41.1 million in the second quarter of 2025 due primarily to an increase in compensation and employee benefits resulting from an increase in the accrual for incentive compensation. Professional fees increased due primarily to merger related costs of $630,000 incurred during the third quarter of 2025, offset partially by a reduction in other professional expenses.

Noninterest expense increased $2.3 million, or 5.9%, during the third quarter of 2025 compared to the same period in 2024 due primarily to an increase in compensation and employee benefits due to annual merit increases in base pay and related incentive compensation expense accruals. Professional fees increased due primarily to merger related costs of $630,000 incurred during the third quarter of 2025.

Income Tax Expense

Income tax expense increased $0.9 million to $3.1 million during the third quarter of 2025, compared to $2.2 million during second quarter of 2025 due to an increase in pre-tax income. Impacting the amount of the increase from the prior quarter was the recognition of $515,000 in income tax expense in the second quarter of 2025 related to the surrender of $8.5 million in BOLI policies.

Income tax expense increased $1.5 million in the third quarter of 2025, compared to same period in 2024 due primarily to higher pre-tax income during the third quarter of 2025.
