The decrease from the prior quarter was primarily due to greater payoffs seen in this quarter outpacing originations in the commercial portfolio.

Securities available for sale totaled $1.34 billion at December 31, 2025 compared to $1.30 billion as of September 30, 2025, and $1.27 billion at December 31, 2024. The mark to market adjustment has improved by $62.4 million since the beginning of 2025 as the Fed has resumed cutting interest rates. The Company anticipates continued rate volatility in the bond market in 2026, which will continue to affect the value of the portfolio.

Total deposits declined to $4.34 billion at December 31, 2025, from $4.40 billion at September 30, 2025 but are up $76.0 million since December 31, 2024. During the fourth quarter of 2025, the Company saw seasonal runoff of public funds totaling $93.4 million. Excluding public funds, the fourth quarter of 2025 saw deposit growth of $35.6 million compared to the third quarter of 2025. For the full year of 2025, excluding brokered CDs, the Company experienced strong deposit growth of $151.0 million, or 3.6%.

Total stockholders’ equity increased to $485.7 million at December 31, 2025, from $465.9 million at September 30, 2025, and $406.0 million at December 31, 2024. The increase was primarily due to an improvement in accumulated other comprehensive income along with increased retained earnings.

Credit Quality

Non-performing loans decreased from $35.3 million at September 30, 2025, to $26.2 million at December 31, 2025, but are up slightly from $22.8 million at December 31, 2024. A single loan relationship totaling $7.3 million that moved into nonaccrual during the third quarter of 2025 paid off during the fourth quarter of 2025. A charge-off of $2.5 million was recognized on the loan prior to the payoff. Nonperforming loans to total loans were 0.79% at December 31, 2025, 1.06% at September 30, 2025, and 0.70% at December 31, 2024. The Company’s loans which were 30-89 days delinquent were $16.9 million at December 31, 2025, or 0.51% of total loans, compared to $16.1 million at September 30, 2025, and $13.0 million at December 31, 2024.

The provision for credit losses and unfunded commitments totaled $2.3 million for the fourth quarter of 2025 compared to $295,000 for the fourth quarter of 2024. The provision in the fourth quarter of 2025 was negatively impacted by the charge-off mentioned above. Annualized net charge-offs as a percentage of average loans were 0.59% for the fourth quarter of 2025, compared to 0.07% for the third quarter of 2025 and 0.08% for the fourth quarter of 2024. In addition to the $2.5 million charge-off discussed previously, the Company had an additional $2.0 million charge-off in the fourth quarter that aided in the workout of another troubled relationship. This $2.0 million figure had been specifically reserved in prior periods. The allowance for credit losses to total loans was 1.11% at December 31, 2025 compared to 1.18% at September 30, 2025, and 1.10% at December 31, 2024.

Net Interest Income

Net interest income was of $37.0 million in the fourth quarter of 2025, compared to $32.7 million in the fourth quarter of 2024. Average interest earning assets increased to $4.94 billion in the fourth quarter of 2025 compared to $4.91 billion in the fourth quarter of 2024. The increase was primarily driven by a $46.4 million increase in average loan balances offset by a decrease in fed funds sold. The net interest margin improved to 3.05% in the fourth quarter of 2025 compared to 3.00% in the third quarter of 2025 and 2.72% in the fourth quarter of 2024. The year-over-year increase in net interest margin was due to higher yields on earning assets and lower funding costs on interest bearing liabilities. The Federal Reserve rate cuts in the back half of 2024 and 2025 have benefitted funding costs, while the lag effects of assets repricing continued to drive earning asset yields higher. The yield on interest earning assets increased from 4.77% in the fourth quarter of 2024 to 4.87% in the fourth quarter of 2025, while the cost of interest-bearing liabilities declined from 2.72% in the fourth quarter of 2024 to 2.43% in the fourth quarter of 2025. With additional cuts to the federal funds rate expected in 2026, the Company expects its net interest margin will continue to expand into 2026 as the Company remains liability sensitive and will benefit from falling interest rates. Excluding acquisition marks and PPP interest, non-GAAP, the Company’s net interest margin was 2.90% in the fourth quarter of 2025, 2.87% in the third quarter of 2025, and 2.56% in the fourth quarter of 2024.

Noninterest Income

Noninterest income increased to $12.1 million in the fourth quarter of 2025 from $11.4 million in the fourth quarter of 2024. The increase was driven by strong performance across multiple business lines. Bank owned life insurance (BOLI) income increased $278,000 during the fourth quarter of 2025 to $891,000 compared to $613,000 in the fourth quarter of 2024. The Company purchased an additional $15.0 million in policies during the first quarter of 2025 and policy crediting rates have increased over the last twelve months. Trust fees increased by $379,000 to $3.1 million in the fourth quarter of 2025 from $2.7 million in the fourth quarter of 2024. The Company continues to grow this line of business through deeper penetration in its acquired markets. Insurance agency commissions increased from $1.3 million in the fourth quarter of 2024 to $1.6 million in the fourth quarter of 2025. The Company received a one-time commission of $94,000 during the quarter and fixed annuity sales increased $174,000 as strong annuity activity continues. Retirement plan commissions increased to $1.0 million in the fourth quarter of 2025 from $719,000 in the fourth quarter of 2024 primarily due to the acquisition of Crest Retirement Advisors LLC in late December of 2024. Net gains on the sale of loans increased to $436,000 in the fourth quarter of 2025 from $282,000 in the fourth quarter of 2024 due to additional mortgage volume compared to the year ago period. Other mortgage banking income declined $179,000 in the fourth quarter of 2025 compared to the fourth quarter of 2024. This was primarily due to the Company incurring $58,000 mortgage servicing impairment in the fourth quarter of 2025. Debit card income declined $208,000 to $2.0 million in the fourth quarter of 2025 compared to the fourth quarter of 2024 primarily due to slightly lower commission income recognized from Mastercard in 2025 compared to 2024. Other noninterest income declined to $523,000 in the fourth quarter of 2025 compared to $856,000 in the fourth quarter of 2024 due to lower SBIC income.

Noninterest Expense

Noninterest expense increased to $29.1 million in the fourth quarter of 2025 from $26.2 million in the fourth quarter of 2024. Salaries and employee benefits increased to $15.4 million in the fourth quarter of 2025 from $14.4 million in the fourth quarter of 2024. The increase was primarily driven by annual raises, the acquisition of Crest Retirement in the fourth quarter of 2024 and higher commission expense from increased revenue in the fee-based businesses. Occupancy and equipment expense increased to $4.5 million in the fourth quarter of 2025 from $4.1 million in the fourth quarter of 2024 due to increased maintenance and software costs in 2025. Professional fees increased to $1.2 million in the fourth quarter of 2025 from $785,000 in the fourth quarter of 2024. Legal expenses were low in the fourth quarter of 2024 due to an accrual adjustment. Merger and core conversion expenses were $925,000 in the fourth quarter of 2025 compared to $92,000 in the fourth quarter of 2025. The Company announced the acquisition of Middlefield Banc Corp. in October of 2025 along with its intention to convert its core system to Jack Henry. The merger expense incurred in 2024 was related to the Company’s acquisition of Crest Retirement Advisors LLC. Advertising and marketing expense was down $257,000 from the figure reported for the quarter ended December 31, 2024, primarily due to accrual reductions in the fourth quarter of 2024. Core processing expense increased to $1.4 million for the quarter ended December 31, 2025, from $1.2 million for the quarter ended December 31, 2024. The increase was due to annual increases and timing differences.

Liquidity

The Company had access to an additional $552.2 million in FHLB borrowing capacity at December 31, 2025, along with $498.5 million in available for sale securities that are available for pledging. The Company’s loan to deposit ratio was 76.1% at December 31, 2025.
