These results highlight the dedication of our employees, the trust of our customers, and the strength of a relationship-based banking model that continues to create value for our shareholders.”

The increases were driven primarily by loan growth and loan and investment securities funded during the quarter at higher rates than those that paid off or matured.

Noninterest Income

Explanations for the more significant fluctuations by period and category are detailed below:

Three months ended September 30, 2026 compared to three months ended June 30, 2026

• The decrease in insurance commissions was driven primarily by contingent commission income received during the three months ended June 30, 2026 related to 2025 performance, partially offset by higher policy renewals during the three months ended September 30, 2026
• The decrease in gain from mortgage loans held for sale was driven primarily by a decrease in mortgage loan originations compared to the prior quarter as a result of seasonality and rate volatility
• The increase in gain on life insurance proceeds was the result of a death benefit received in the current quarter
• The increase in other was driven primarily by an annual check ordering volume incentive during the current quarter

Three months ended September 30, 2026 compared to three months ended September 30, 2025

• The decrease in gain from mortgage loans held for sale was driven primarily by a decrease in loan originations primarily as a result of rate volatility

Noninterest Expense

Explanations for the more significant fluctuations by period and category are detailed below:

Three months ended September 30, 2026 compared to three months ended June 30, 2026

• The increase in salaries and employee benefits was driven primarily by higher employee insurance expense, higher incentive compensation and higher insurance producer commissions
• The decrease in equipment was driven primarily by timing of purchases of computer hardware and software
• The increase in other tax was driven primarily by earned income tax credits received in the prior quarter as a result of community investment contributions
• The decrease in other was driven primarily by the community investment contributions incurred in the prior quarter

Three months ended September 30, 2026 compared to three months ended September 30, 2025

• The increase in salaries and employee benefits was driven primarily by higher incentive compensation expenses, merit increases and higher employee insurance expense
• The increase in professional services was driven primarily by higher legal and advisory services related to corporate initiative expenses, including software modernization and employee stock purchase plan fees
• The increase in other tax was driven primarily by asset and capital growth
• The decrease in merger-related was driven by the lack of Acquisition related expenses in the current period

Loans and Asset Quality

September 30, 2026 compared to June 30, 2026

• The $8.4 million increase in total loans from June 30, 2026 was driven primarily by:
  • Real estate construction portfolio growth of $13.3 million across both commercial and residential portfolios
  • Residential mortgage portfolio growth of $3.1 million, partially offset by;  
  • Commercial real estate portfolio decline of $8.6 million, driven primarily by a decline in non-owner occupied balances ($13.4 million) and farmland ($1.5 million) partially offset by growth in owner-occupied balances ($3.6 million) and multifamily ($1.8 million)

• The allowance for credit losses was $25.0 million, an increase of $970 thousand. The increase was driven primarily by a specific allowance allocation on a relationship in the commercial and industrial portfolio and, to a lesser extent, loan growth; the bank does not believe the increase is indicative of a general weakness in the overall loan portfolio but rather the increase is driven primarily by an isolated credit issue specific to an individual borrower
• Total non-performing loans to total loans, net of unearned income were 0.45% compared to 0.41% driven primarily by the migration of four loans to three unrelated borrowers totaling $1.4 million to nonaccrual partially offset by paydowns of $657 thousand

September 30, 2026 compared to September 30, 2025

• The increase in total loans of $69.9 million was driven primarily by commercial real estate growth of $60.6 million concentrated in farmland ($45.2 million), multi-family ($22.3 million), owner-occupied balances ($23.3 million) and 1-4 family ($9.2 million), partially offset by a decline in non-owner occupied balances ($34.0 million)
• The allowance for credit losses increased by $1.3 million. The increase was driven primarily by a specific reserve allocated to a relationship in the commercial and industrial portfolio and, to a lesser extent, loan growth
• Total non-performing loans to total loans, net of unearned income was 0.45% compared to 0.43%

Deposits

September 30, 2026 compared to June 30, 2026

• The increase in noninterest-bearing demand deposits was driven primarily by promotional incentives on commercial checking accounts and a seasonal influx of municipal deposits
• The decrease in time deposits was driven primarily by the pay down of $30.0 million of brokered deposits and partially offset by growth in retail time deposits

September 30, 2026 compared to September 30, 2025

• The increase in noninterest-bearing demand deposits was driven primarily by promotional incentives on commercial checking accounts
• The increase in interest-bearing demand deposits was driven primarily by growth in commercial and retail balances and accounts due to new customer relationships acquired
• The decrease in money market balances was driven primarily by attrition of higher cost money market deposits from the Acquisition

Borrowings

Total borrowings were $331.4 million at September 30, 2026, an increase of $8.3 million and a decrease of $4.4 million compared to June 30, 2026 and September 30, 2025, respectively. The increase compared to June 30, 2026 was due to seasonal increases in repurchase agreement balances and greater balances on accounts collateralizing derivative contracts given the recent rise in market rates. The decrease compared to September 30, 2025 was a result of lower securities sold under repurchase agreements partially offset by higher balances on accounts collateralizing derivative contracts.

Stockholders’ Equity

Total stockholders’ equity was $420.5 million at September 30, 2026 compared to $423.3 million at June 30, 2026 and $408.6 million at September 30, 2025. The decrease at September 30, 2026 compared to June 30, 2026 was driven primarily by a $15.4 million unrealized loss on investment securities, dividends paid of $4.3 million, partially offset by net income of $15.7 million. The increase at September 30, 2026 compared to September 30, 2025 was driven primarily by growth in retained earnings partially offset by changes in unrealized losses in available for sale investment securities. Tangible book value¹ per share was $33.26, $33.42 and $30.87 at September 30, 2026, June 30, 2026 and September 30, 2025, respectively.
