FIRST MID BANCSHARES, INC.

Net Interest Income

The largest source of revenue for the Company is net interest income. Net interest income represents the difference between total interest income earned on earning assets and total interest expense paid on interest-bearing liabilities. The amount of interest income is dependent upon many factors, including the volume and mix of earning assets, the general level of interest rates and the dynamics of changes in interest rates. The cost of funds necessary to support earning assets varies with the volume and mix of interest-bearing liabilities and the rates paid to attract and retain such funds.

Net interest income is the excess of interest received from earning assets over interest paid on interest-bearing liabilities. For analytical purposes, net interest income is presented on a full tax equivalent ("TE") basis in the table that follows. The federal statutory rate in effect of 21% for 2025 and 2024 was used. The TE analysis portrays the income tax benefits associated with the tax-exempt assets. The year-to-date net yield on interest-earning assets excluding the TE adjustments of $2.3 million and $2.3 million for 2025 and 2024, respectively were 3.66% and 3.26% at September 30, 2025 and 2024, respectively.

The Company’s average balances, fully tax equivalent interest income and interest expense, and rates earned or paid for major balance sheet categories are set forth for the three and nine months ended September 30, 2025 and 2024 in the following table (dollars in thousands):

The tax-exempt income is shown on a tax equivalent basis.

Nonaccrual loans and loans held for sale are included in the average balances. Balances are net of unaccreted discount related to loans acquired.

During the first quarter 2025, the Company changed the methodology utilized for the calculation of net interest margin to be more consistent with what is typically used by peer banks and research analysts. The calculation now is the annualized net interest income on a tax equivalent basis divided by average interest earning assets.

Changes in net interest income may also be analyzed by segregating the volume and rate components of interest income and interest expense. The following table summarizes the approximate relative contribution of changes in average volume and interest rates to changes in net interest income for the three and nine months ended September 30, 2025, compared to the same period in 2024 (in thousands):

Changes attributable to the combined impact of volume and rate have been allocated proportionately to the change due to volume and the change due to rate.

•

The following table sets forth the major components of other expense for the three and nine months ended September 30, 2025 and 2024 (dollars in thousands):

Following are explanations for the significant changes in these other expense categories for the three and nine months ended September 30, 2025 compared to the same period in 2024:

•

The increase in salaries and employee benefits, the largest component of other expense, is primarily due to regularly scheduled annual raises and increase in expense accrued for incentive compensation to be paid in 2026 based on overperformance compared to the 2025 budgeted net income. There were 1,178 and 1,207 full-time equivalent employees at September 30, 2025 and 2024, respectively.

•

The increase in occupancy and equipment and legal and professional fees expenses are primarily due to nonrecurring technology project expenses in the first three quarters of 2025.
