SUMMARY OF FOURTH QUARTER RESULTS

Net Interest Income

Net interest income in the fourth quarter of 2025 totaled $14.8 million, representing an increase of $695,000, or 4.9%, compared to the previous quarter and an increase of $2.4 million, or 19.3%, compared to the same quarter of the prior year. The increase in net interest income this quarter compared to the prior quarter was driven by higher rates on loans and investments despite lower average balances, coupled with lower interest expense on deposits and other borrowings. The net interest margin for the fourth quarter of 2025 was 4.03%, an increase of 20 basis points as compared to the prior quarter and an increase of 52 basis points from 3.51% during the fourth quarter of the prior year. The average tax-equivalent yield on the loan portfolio increased three basis points to 6.40% in the fourth quarter, while the yield on investment securities grew to 3.39%.

Compared to the third quarter of 2025, interest on deposits decreased $272,000, or 5.0%, due to lower rates, partially offset by increased average balances. Interest on other borrowed funds decreased $325,000 from the third quarter of 2025, due to lower rates and average balances. The average rate on interest-bearing deposits decreased 12 basis points from the prior quarter, to 2.06%, primarily due to lower rates on money market and checking accounts and certificates of deposit. The average rate on other borrowed funds decreased 16 basis points to 4.93% in the fourth quarter of 2025.

Non-Interest Income

Non-interest income totaled $3.9 million for the fourth quarter of 2025, a decrease of $169,000 from the previous quarter. The decrease in non-interest income during the fourth quarter of 2025 was primarily due to a loss of $101,000 on sales of lower-yielding investment securities as part of our ongoing strategy to improve future interest income.

Non-Interest Expense

During the fourth quarter of 2025, non-interest expense totaled $12.3 million, an increase of $1.0 million, or 9.0%, compared to the prior quarter and an increase of $386,000, or 3.3%, compared to the same period in the prior year. Compared to the prior quarter, the increase in non-interest expense was primarily due to increases of $511,000 in compensation and benefits expense and $173,000 in professional fees, along with a valuation allowance recorded on repossessed assets held for sale of $356,000. The increase in compensation and benefits was attributable to an increase in the number of employees coupled with higher incentive compensation costs tied to improved company performance, while the increase in professional fees was primarily due to higher audit and consulting costs.

Income Tax Expense

Landmark recorded income tax expense of $1.2 million in the fourth quarter of 2025, compared to $1.1 million in the third quarter of 2025. The effective tax rate was 20.0% in the fourth quarter of 2025, compared to 18.7% in the third quarter of 2025.

Balance Sheet Highlights

As of December 31, 2025, gross period-end loans totaled $1.1 billion, a decrease of $6.3 million from the prior quarter, while average loans also declined $2.1 million. This decrease in period-end loans was primarily driven by lower commercial loans (decline of $8.5 million), and one-to-four family residential real estate (decline of $6.3 million), offset by growth in commercial real estate (growth of $4.7 million) and agriculture (growth of $2.9 million) loans. Investment securities available-for-sale decreased $1.9 million during the fourth quarter of 2025 primarily due to maturities occurring during the quarter.

Period-end deposit balances increased $63.4 million to $1.4 billion at December 31, 2025, an annualized increase of 19.0% compared to the prior quarter. The increase in deposits was driven by an increase in money market and checking accounts of $71.6 million, partially offset by a decrease in certificates of deposit of $12.1 million. The increase in money market and checking accounts was primarily driven by seasonal growth in public fund deposit account balances. Total period-end borrowings decreased $79.8 million during the fourth quarter of 2025. At December 31, 2025, the loan to deposits ratio was 79.1% compared to 83.4% in the prior quarter.

Stockholders’ equity increased to $160.6 million (book value of $26.44 per share) as of December 31, 2025, from $155.7 million (book value of $25.64 per share) as of September 30, 2025. The increase in stockholders’ equity was primarily due to net earnings for the quarter net of dividends paid, coupled with a decrease in accumulated other comprehensive losses (lower unrealized net losses on investment securities). The ratio of equity to total assets increased to 10.00% on December 31, 2025, from 9.63% on September 30, 2025.

The allowance for credit losses totaled $12.5 million, or 1.12% of total gross loans, as of December 31, 2025, compared to $12.3 million, or 1.10% of total gross loans, on September 30, 2025. Net loan charge-offs totaled $341,000 in the fourth quarter of 2025, compared to $2.3 million during the third quarter of 2025 and $219,000 in the fourth quarter of the prior year. Net charge-offs were elevated in the third quarter of 2025 due to the charge-off of a single commercial credit previously discussed. A provision for credit losses of $500,000 was recorded in the fourth quarter of 2025 compared to $850,000 in the third quarter of 2025.

Non-performing loans totaled $10.0 million, or 0.90% of gross loans, at December 31, 2025, compared to $10.0 million, or 0.89% of gross loans, at September 30, 2025. Loans 30-89 days delinquent totaled $4.3 million, or 0.38% of gross loans, as of December 31, 2025, compared to $4.9 million, or 0.43% of gross loans, as of September 30, 2025.
