Removed

The Company’s business, operations and financial performance may be affected by the macroeconomic impacts resulting from pandemics, and the Company’s financial results in future periods could differ significantly from the Company’s historical results. The extent to which the Company’s business will be affected will depend on a variety of factors, many of which are outside of the Company’s control, including the persistence of the pandemic, the actions of governmental authorities, changes in customer preferences, impacts on economic activity, and the possibility of recession or financial market instability.

Competition among providers of financial services in markets, particularly within California, is intense. The Company competes with other financial and bank holding companies, state and national commercial banks, savings and loan associations, consumer finance companies, credit unions, securities brokerages, insurance companies, mortgage banking companies, money market mutual funds, asset-based non-bank lenders, government sponsored or subsidized lenderslenders, Internet-based “fintech” companies and other financial services providers. Many of these competitors have substantially greater financial resources, lending limits and technological resources than the Company and are able to offer a broader range of products and services. Many competitors offer lower interest rates and more liberal loan terms that appeal to borrowers but adversely affect net interest margin and assurance of repayment. The Company is increasingly faced with competition in many of its products and services by non-bank providers who may have competitive advantages of size, access to potential customers and fewer regulatory requirements, such as “fintech” lenders. Failure to compete effectively for deposit, loan and other banking customers in any of the lines of business could cause the Company to lose market share, slow or reverse growth rate or suffer adverse effects on financial condition, results of operations or profitability.

The Company's allowance for credit losses on loans is maintained at a level considered adequate to provide for expected losses based on historical loss rates adjusted for current and expected conditions over a forecast period. These include conditions unique to individual borrowers, as well as overall loan loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing and forecasted economic conditions, or credit protection agreements and other factors. Loans that share common risk characteristics are segregated into pools based on common characteristics, which are primarily determined by loan, borrower, or collateral type. Historical loss rates are determined for each pool. Loans that do not share risk characteristics with other loans in the pools are evaluated individually. See Note 1 “Business and Accounting Policies” to the consolidated financial statements for additional information.

Management monitors the Company’s interest rate risk using a purchasedlicensed third party simulation model, which is periodically assessed using supervisory guidance issued by the Board of Governors of the Federal Reserve System, SR 11-7 “Guidance on Model Risk Management.” Management measures its exposure to interest rate risk using a dynamic composition simulation and static simulation. Within the dynamic composition simulation, Management makes assumptions regarding the expected change in the volume of financial instruments given the assumed change in market interest rates. Within the static simulation, cash flows are assumed redeployed into like financial instruments at prevailing rates and yields. Both simulations are used to measure expected changes in net interest income assuming various levels of change in market interest rates.

Banking industry deposits, including for Westamerica Bank, grew rapidly in 2020 and 2021 due to the injection of fiscal stimulus into the United States economy, including Paycheck Protection Program loans, and an easing of Federal Reserve monetary policy, both in response to the COVID pandemic. Federal Reserve monetary policy easing included reduction in the federal funds rate to a range of 0.00% to 0.25% and net purchases of Treasury securities and agency mortgage-backed securities, which increase the money supply and aggregate bank deposits. Subsequently, inflation rose considerably while employment conditions remained strong. In 2022 and 2023, the Federal Reserve’s monetary policy reversed to tightening, in an effort to reduce inflation. The monetary policy tightening included increasing and keeping the federal funds rate to a range of 5.25% to 5.50% and net reductions of Treasury securities and agency mortgage-backed securities, which reduce the money supply and aggregate bank deposits. Westamerica Bank’s deposit totals are subject to both the fiscal policies of the United States government and monetary policies of the Federal Reserve; the decline in Westamerica Bank deposits during 2023 was influenced by these fiscal and monetary policies. In addition, the Internal Revenue Service (“IRS”) declared every county in which Westamerica Bank operates as Natural Disaster Areas due to 2022-2023 winter storms; the IRS and California Franchise Tax Board extended the 2022 tax filing deadline and 2023 tax installment payment due dates to November 16, 2023. Management believes this deferment of tax payment deadlines impacted deposit totals in the fourth quarter 2023 as customers paid their federal and California tax obligations. Total deposits declined $462,417 thousand from December 31, 2023 to December 31, 2024 due to competitive financial product pricing.

Management segmented debt securities held to maturity, selected methods to estimate losses for each segment, and measured a loss estimate. Agency mortgage-backed securities were assigned no credit loss allowance due to the perceived backing of government sponsored entities. Corporate securities held to maturity were individually evaluated for expected credit loss by evaluating the issuer’s financial condition, profitability, cash flows, and credit ratings. The Company has evaluated each issuer’s historical financial performance and ability to service debt payments throughout and following the 2008-2009 recession. The Company has an expectation that nonpayment of the amortized cost basis continues to be zero. At MarchJune 31,30, 2026, no credit loss allowance was assigned to corporate securities held to maturity based on evaluation of each individual issuer’s historical financial performance throughout full business cycles. Municipal securities were evaluated for risk of default based on credit rating and remaining term to maturity using Moody’s risk of default factors; Moody’s loss upon default factors were applied to the assumed defaulted principal amounts to estimate the amount for credit loss allowance. Allowance for credit losses related to debt securities held to maturity was $1 thousand related to municipal securities at MarchJune 31,30, 2026 and December 31, 2025, reflecting the expected credit losses on debt securities held to maturity.

The Company’s asset and liability position was generally “asset sensitive” at MarchJune 31,30, 2026, based on the interest rate assumptions applied to the simulation model. An “asset sensitive” position results in a larger change in interest income than in interest expense resulting from application of assumed interest rate changes. However, in the dynamic simulation, an assumed decline in interest rates is expected to result in improved deposit balances funding higher earning asset levels. Further, in the dynamic simulation, no change in interest rates is expected to result in a decline in net interest income as asset yields remain stable and deposit costs rise as the Bank negotiates deposit rates with customers in the current environment.
