The primary goal of asset/liability management is to maximize net interest income within the interest rate risk limits set by the ALCO. Interest rate risk is monitored through the use of two complementary measures: static gap analysis and earnings simulation modeling. While each measurement has limitations, taken together they represent a reasonably comprehensive view of the magnitude of interest rate risk in the Company, the level of risk through time, and the amount of exposure to changes in certain interest rate relationships.

Static gap analysis measures the amount of repricing risk embedded in the balance sheet at a point in time. It does so by comparing the differences in the repricing characteristics of assets and liabilities. A gap is defined as the difference between the principal amount of assets and liabilities that reprice within a specified time period. The Company's cumulative one-year gap at September 30, 2025 was (11.90)% of total assets compared to (15.98)% of total assets at December 31, 2024. Core deposits with non-contractual maturities are presented based upon historical patterns of balance attrition and pricing behavior, which are reviewed at least annually.

The gap repricing distributions include principal cash flows from residential mortgage loans and mortgage-backed securities in the time frames in which they are expected to be received. Mortgage prepayments are estimated by applying industry median projections of prepayment speeds to portfolio segments based on coupon range and loan age.

A summary of the Company's static gap, as of September 30, 2025, is presented in the following table:

The earnings simulation model forecasts capture the impact of changing interest rates on one-year and two-year net interest income. The modeling process calculates changes in interest income received and interest expense paid on all interest-earning assets and interest-bearing liabilities reflected on the Company's consolidated balance sheet. None of the assets used in the simulation are held for trading purposes. The modeling is done for a variety of scenarios that incorporate changes in the absolute level of interest rates as well as basis risk, as represented by changes in the shape of the yield curve and changes in interest rate relationships. Management evaluates the effects on income of alternative interest rate scenarios against earnings in a stable interest rate environment. This analysis is also most useful in determining the short-run earnings exposures to changes in customer behavior involving loan payments and deposit additions and withdrawals.

The Company's most recent simulation model calculates projected impact on net interest income in scenarios where short-term interest rates gradually decrease by two percentage points, gradually decreases by one percentage point, and where short- term rates gradually increase by two percentage points. The Company's modeling as of September 30, 2025 projects net interest income would increase by approximately 3.2% if short-term rates affected by FOMC actions fall gradually by two percentage points over the next year, and would increase by approximately 1.6% if short term rates gradually fall by one percentage point over the next year; net interest income would decrease by approximately 3.6% if rates rise gradually by two percentage points over the next year. Each scenario is within the ALCO's policy limit of a decrease in net interest income of no more than 10.0% given a 2.0% move in interest rates, up or down. Management believes this reflects a reasonable interest rate risk position. In year two, and assuming no additional movement in rates, the model forecasts that net interest income would be higher than that earned in the first year of a stable rate environment by 17.0% in the two percentage point falling-rate scenario, and higher by 14.8% in the one percentage point falling rate scenario; net interest income would be higher than that earned in a stable rate environment by 4.5% in a two percentage point rising rate scenario, when compared to the year-one base scenario. Each year two scenario is well within the ALCO's policy limit of a decrease of no more than 20% given a 2.0% move in interest rates, up or down. A summary of the Bank's interest rate risk simulation modeling, as of September 30, 2025 and December 31, 2024 is presented in the following table:

This dynamic simulation model includes assumptions about how the balance sheet is likely to evolve through time and in different interest rate environments. Loans and deposits are projected to maintain stable balances. All maturities, calls and prepayments in the securities portfolio are assumed to be reinvested in similar assets. Mortgage loan prepayment assumptions are developed from industry median estimates of prepayment speeds for portfolios with similar coupon ranges and seasoning. Non-contractual deposit volatility and pricing are assumed to follow historical patterns. The sensitivities of key assumptions are analyzed annually and reviewed by the ALCO.

This sensitivity analysis does not represent a Company forecast and should not be relied upon as being indicative of expected operating results. These hypothetical estimates are based upon numerous assumptions including, among others, the nature and timing of interest rate levels, yield curve shape, prepayments on loans and securities, pricing decisions on loans and deposits, and reinvestment/ replacement of asset and liability cash flows. While assumptions are developed based upon current economic and local market conditions, the Company cannot make any assurances as to the predictive ability of these assumptions, including how customer preferences or competitor influences might change.
