Loans receivable increased $14.1 million, or 0.3%, during the fourth quarter of 2025 due to new loan production for the quarter offset partially by an elevated level of prepaid and closed loans. New loans funded during the fourth quarter of 2025 were $173.1 million, compared to $174.5 million during the third quarter of 2025.

Loan payoffs increased to $74.5 million, compared to $55.8 million in the prior quarter.

Commercial and industrial loans decreased $1.1 million, or 0.1%, during the fourth quarter of 2025, due primarily to pay downs on outstanding balances, partially offset by new loan production of $28.8 million. Owner-occupied commercial real estate ("CRE") loans increased $12.1 million, or 1.2%, during the fourth quarter of 2025, due primarily to new loan production of $40.0 million, partially offset by pay downs on outstanding balances.

Residential construction loans increased by $4.9 million, or 5.4%, during the quarter, due primarily to new loan production.

Total deposits increased $62.7 million, or 1.1%, to $5.92 billion at December 31, 2025 from $5.86 billion at September 30, 2025. Non-maturity deposits increased by $75.1 million, or 1.5%, from September 30, 2025, due primarily to an increase in customer balances in interest bearing demand accounts. The increase in non-maturity deposits was partially offset by a decrease of $12.4 million in certificates of deposit accounts.

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

Total stockholders' equity increased $17.4 million, or 1.9%, to $921.5 million at December 31, 2025, compared to $904.1 million at September 30, 2025, due primarily to $22.2 million of net income recognized for the quarter and a $2.2 million decrease in accumulated other comprehensive loss. These increases were partially offset by $8.2 million in dividends paid to common shareholders during the quarter.

The Company and Bank continued to maintain capital levels in excess of the applicable regulatory requirements for them both to be categorized as “well-capitalized” at December 31, 2025.

Allowance for Credit Losses and Provision for Credit Losses

The allowance for credit losses ("ACL") on loans as a percentage of loans receivable was 1.10% at December 31, 2025 compared to 1.13% at September 30, 2025. The decrease in the ACL as a percentage of loans was due primarily to a change in the mix of loans due to decreases in the real estate construction and land development segment which has a higher ACL as a percentage of loans, offset by an increase in other segments with a lower ACL as a percentage of loans. During the fourth quarter of 2025, the Company recorded a $0.9 million reversal of provision for credit losses on loans, compared to a $1.6 million provision during the third quarter of 2025.

During the fourth quarter of 2025, the Company recorded a $95,000 provision for credit losses on unfunded commitments compared to a $212,000 provision during the third quarter of 2025. The provision for credit losses on unfunded commitments during the fourth quarter of 2025 was due primarily to a decrease in utilization rates.

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

Credit Quality

Classified loans (loans rated substandard or worse) increased $22.4 million from the prior quarter, resulting in the percentage of classified loans to loans receivable increasing to 2.4% at December 31, 2025, compared to 2.0% at September 30, 2025.

Nonaccrual loans increased by $3.4 million during the fourth quarter of 2025 due primarily to the migration of three non-owner occupied CRE loans totaling $3.9 million, offset partially by principal payments received. The following table illustrates changes in nonaccrual loans during the periods indicated:

Net Interest Margin and Net Interest Income

Net interest margin increased 8 basis points to 3.72% during the fourth quarter of 2025, from 3.64% during the third quarter of 2025.

The yield on interest earning assets decreased one basis point to 5.03% for the fourth quarter of 2025, compared to 5.04% for the third quarter of 2025. The yield on loans receivable increased one basis point to 5.54% during the fourth quarter of 2025, compared to 5.53% during the third quarter of 2025 as new loans were booked and adjustable rate loans repriced at higher rates, partially offset by the impacts of the three fed funds rate cuts occurring during the last four months of the year.

The cost of interest bearing deposits decreased six basis points to 1.83% for the fourth quarter of 2025, from 1.89% for the third quarter of 2025. This decrease was primarily due to a decrease in certificate of deposit rates.

Net interest income increased $1.0 million, or 1.7%, during the fourth quarter of 2025 compared to the third quarter of 2025 due to a decrease in interest expense of $1.6 million, offset partially by a $0.6 million decrease in total interest income.

Net interest margin increased 36 basis points to 3.72% during the fourth quarter of 2025, compared to 3.36% for the same period in the prior year. Net interest income increased $4.6 million, or 8.6%, during the fourth quarter of 2025 compared to the same period in the prior year. 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 and lower borrowing balances.

(3) Yields on tax-exempt loans and securities have not been stated on a tax-equivalent basis.

Noninterest Income

Noninterest income decreased $338,000 to $8.0 million during the fourth quarter of 2025 from $8.3 million during the third quarter of 2025. The decrease was due primarily to decreases in card revenue and a decrease in other income, offset partially by an increase in interest rate swap fees due to increased swap activity and an increase in bank owned life insurance ("BOLI") income due to the recognition of a death benefit.

Noninterest income increased $4.7 million during the fourth quarter of 2025 from the same period in 2024 due primarily to a $3.9 million loss recognized in the fourth quarter of 2024 resulting from the sale of investment securities as part of the strategic repositioning of the Company's balance sheet and an increase in BOLI income as the Company incurred $508,000 in costs related to the restructuring of the BOLI portfolio in the fourth quarter of 2024.

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

Noninterest Expense

Noninterest expense decreased $132,000, or 0.3%, to $41.5 million during the fourth quarter of 2025, compared to $41.6 million in the third quarter of 2025. Compensation and employee benefits increased due to an increase in the accrual for incentive compensation. Professional fees decreased due primarily to lower merger related costs recognized in the fourth quarter of 2025 associated with the acquisition of Olympic.

Noninterest expense increased $1.9 million, or 4.9%, during the fourth 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, an increase in benefit expense and incentive compensation expense accruals.

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


	Quarter Ended						Quarter Over Quarter Change				Prior Year Quarter Change

Income Tax Expense

Income tax expense increased $305,000 to $3.4 million during the fourth quarter of 2025, compared to $3.1 million during the third quarter of 2025 due to an increase in pre-tax income.

Income tax expense and the effective income tax rate decreased in the fourth quarter of 2025, compared to same period in 2024 due primarily to additional tax expense of $2.4 million related to BOLI restructuring during the fourth quarter of 2024, partially offset by increased income tax expense on higher pre-tax income during the fourth quarter of 2025.

The following table presents the income tax expense and related metrics and the change for the periods indicated:
