Our core systems conversion is already delivering enhancements in customer experience and has empowered our ability to offer innovative new products and services.

Highlights

Net Interest Income

The net interest margin improved when the fourth quarter of 2025 is compared with the third quarter of 2025 and when the twelve month periods ended December 31, 2025 and December 31, 2024 are compared, due to lower deposit costs and higher loan yields.

Noninterest Income

During the fourth quarter of 2025, other income increased due to dividends from certain equity method investments and higher insurance and investment commissions when compared with the third quarter of 2025. Noninterest income during the third quarter of 2025 reflected receipt of an incentive payment recorded in credit and debit card fees, a large estate fee included in trust income, and higher income from the Bank's secondary market mortgage operation. When comparing the

twelve month periods ended December 31, 2025 and 2024, incentive payments reflected in credit and debit card fees, higher insurance and securities commissions recorded in other income and growth in trust income drove the year-over-year increase.

Noninterest Expense

Noninterest expense increased when the fourth quarter of 2025 is compared with the third quarter of 2025 due to an increase in salaries and employee benefits, occupancy expense and data processing expense. When comparing the twelve month periods ended December 31, 2025 and 2024, higher noninterest expense is reflective of both the core system conversion and operations of the combined Company, which include the acquired operations of FCB. Noninterest expense in 2024 includes merger expenses related to the FCB acquisition.

Securities and Borrowings

During the fourth quarter of 2025, the Company invested $35 million in securities and fully repaid borrowings as of December 31, 2025. Analysis as of December 31, 2025 did not indicate credit risk concerns with any of the Company’s securities.

Deposits
Deposits increased from the end of the third quarter to December 31, 2025. Company’s depositors within its market areas are diverse and include individuals, businesses and municipalities. The Company does not have any brokered deposits. Depositors are insured up to the FDIC maximum of $250 thousand. Municipal deposits, which account for 23.0% of the Company’s deposits, have additional security from bonds pledged as collateral, in accordance with state regulation. Of the Company’s non-municipal deposits, approximately 19.75% are uninsured.

Liquidity

The Company’s liquidity position remains solid. The Company maintains borrowing lines with the Federal Home Loan Bank of Atlanta (“FHLB”) and the Federal Reserve that provide substantial borrowing capacity. Combined with a low loan-to-deposit ratio, positive results of the latest liquidity stress testing and success of deposit marketing, the Company believes it is well positioned to meet foreseeable liquidity demands.

Loans and Credit Quality

Loans decreased from September 30, 2025, primarily driven by large payoffs in commercial real estate loans. The Company is positioned to continue to make every loan that meets its underwriting standards. Loan metrics continue to reflect low credit risk, with low charge-off and past due levels. The Company's measurement of credit risk resulted in a recovery to the allowance for credit losses on loans for the fourth quarter of 2025, reflecting an improvement in certain economic factors.

Stockholders’ Equity

The Company paid a semiannual dividend of $0.78 to shareholders on December 1, 2025, resulting in a total dividend for 2025 of $1.51 per share. Stockholders’ equity increased when December 31, 2025 is compared with September 30, 2025 due to net income and improvement in unrealized losses on available for sale securities, which are reflected, net of tax, in accumulated other comprehensive loss. Accumulated other comprehensive loss is excluded from the Bank’s regulatory capital and does not affect regulatory capital ratios. The Bank is considered well capitalized, with capital ratios substantially higher than minimum regulatory requirements, and meets all requirements for borrowing from the FHLB.
