Westamerica Bancorporation: Form 10-Q for the period ended Sep 30, 2025

WESTAMERICA BANCORPORATION

FINANCIAL SUMMARY

(In thousands, except per share data)

The above financial summary has been derived from the Company's unaudited consolidated financial statements. This information should be read in conjunction with those statements, notes and the other information included elsewhere herein. Percentages under the heading "Financial Ratios" are annualized with the exception of the efficiency ratio.

(1) Yields on securities and certain loans have been adjusted upward to a "fully taxable equivalent" ("FTE") basis in order to reflect the effect of income which is exempt from federal income taxation at the current statutory tax rate.

(2) The efficiency ratio is defined as noninterest expense divided by total revenue (net interest income on an FTE basis and noninterest income).

Financial Overview

Westamerica Bancorporation and subsidiaries (collectively, the “Company”) reported net income of $28.3 million or $1.12 diluted earnings per common share (“EPS”) in the three months ended, September 30, 2025 compared with net income of $35.1 million or $1.31 EPS for the third quarter 2024. The third quarter 2024 results included a $202 thousand bank owned life insurance gain and a $1.4 million gain on sale of other assets equivalent to $0.04 EPS. The Company reported net income of $88.4 million or $3.40 EPS for the nine months ended September 30, 2025, including a $550 thousand reversal of provision for credit losses and a $208 thousand bank owned life insurance gain, which increased EPS $0.02. The Company reported net income of $106.9 million or $4.01 EPS for the nine months ended September 30, 2024. Results for the nine months ended September 30, 2024 included a $202 thousand life insurance gain and a $1.4 million gain on sale of other assets equivalent to $0.04 EPS.

The Federal Open Market Committee of the Federal Reserve Board (“FOMC”) reduced the target federal funds rate by 0.25 percent to the range of 3.75 to 4.00 percent in October 2025. The FOMC press release in October stated, “Available indicators suggest that growth of economic activity has been expanding at a moderate pace. Job gains have slowed, and the unemployment rate has edged up but remains low through August… Inflation has moved up since earlier in the year and remains somewhat elevated. The Committee seeks to achieve maximum employment and inflation at the rate of 2 percent over the long run. Uncertainty about the economic outlook remains elevated. The Committee is attentive to the risks to both sides of its dual mandate and judges that downside risks to employment rose in recent months” The interest rate paid on reserve balances at the Federal Reserve Bank was reduced to 3.90% effective October 30, 2025 from 4.15% effective September 18, 2025. The Bank maintains reserve balances at the Federal Reserve Bank; the amount that earns interest is identified as “interest-bearing cash”.

Management continues to evaluate the impacts of inflation, the Federal Reserve’s monetary policy, the impacts of tariffs, international trade tensions, the on-going government shutdown and climate changes on the Company’s business. The banking industry could experience significant volatility as it did with several regional bank failures in 2023. Industrywide concerns could develop related to liquidity, deposit outflows and unrealized losses on investment debt securities. These events and concerns could adversely affect the Company’s ability to effectively fund its operations. Any one or a combination of such risk factors, or other factors, could materially adversely affect the Company's business, financial condition, results of operations and prospects. The extent of the impact on the Company’s results of operations, cash flow, liquidity, and financial performance, as well as the Company’s ability to execute near- and long-term business strategies and initiatives, will depend on numerous evolving factors and future developments, which are highly uncertain and cannot be reasonably predicted.

The Company presents its net interest margin and net interest income on a fully taxable equivalent (“FTE”) basis using the current statutory federal tax rate. Management believes the FTE basis is valuable to the reader because the Company’s loan and investment securities portfolios contain municipal loans and securities that are federally tax exempt. The Company’s tax exempt loans and securities composition may not be similar to that of other banks, therefore in order to reflect the impact of the federally tax exempt loans and securities on the net interest margin and net interest income for comparability with other banks, the Company presents its net interest margin and net interest income on an FTE basis.

The Company’s significant accounting policies (see Note 1, “Summary of Significant Accounting Policies,” to Financial Statements in the Company’s 2024 Form 10-K and Note 2 “Accounting Policies” in this Form 10-Q) are fundamental to understanding the Company’s results of operations and financial condition. The Company adopted the following new accounting guidance:

FASB ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, was issued November 27, 2023. The ASU requires disclosure of certain significant segment expenses and other items, the title and position of the chief operating decision maker and information about how the reported measures of segment profit or loss are used in assessing segment performance. The ASU became effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements.

Net Income

Following is a summary of the components of net income for the periods indicated:

(In thousands, except per share data)

Net income for the three months ended September 30, 2025 decreased $6.8 million compared with the three months ended September 30, 2024 primarily due to decreases in net interest and loan fee income (FTE) and noninterest income, partially offset by lower noninterest expense and tax provision (FTE). Net interest and loan fee income (FTE) decreased $8.6 million in the three months ended September 30, 2025 compared with the three months ended September 30, 2024 due to lower average balances of investment securities and loans, lower yield on investment securities and interest-bearing cash, and higher rate on interest-bearing deposits, partially offset by higher average balances of interest-bearing cash and lower average balances of bank term funding program borrowings. Based on the results of its current expected credit losses (“CECL”) model and Management’s estimate of credit losses over the remaining life of its loans, the Company provided no provision for credit losses in the three months ended September 30, 2025 and September 30, 2024. Noninterest income in the three months ended September 30, 2025 decreased $1.8 million compared with the three months ended September 30, 2024 primarily because the three months ended September 30, 2024 results included a $1.4 million gain on sale of other assets. Noninterest expense in the three months ended September 30, 2025 decreased $509 thousand compared with the three months ended September 30, 2024 primarily due to lower salaries and benefits and lower estimated operating losses from limited partnership investments, partially offset by an increase in professional fees. The tax rate (FTE) was 26.0% for the three months ended September 30, 2025 and 27.1% for the three months ended September 30, 2024.

Net income for the nine months ended September 30, 2025 decreased $18.6 million compared with nine months ended September 30, 2024 primarily due to decreases in net interest and loan fee income (FTE) and noninterest income, partially offset by lower noninterest expense and tax provision (FTE). Net interest and loan fee income (FTE) decreased $27.9 million in the nine months ended September 30, 2025 compared with the nine months ended September 30, 2024 due to lower average balances of investment securities and loans, lower yield on investment securities and interest-bearing cash, and higher rate on interest-bearing deposits, partially offset by higher average balances of interest-bearing cash and lower average balances of bank term funding program borrowings. During the nine months ended September 30, 2025, the Company recorded a $550 thousand reversal of provision for credit losses, which was included in the first quarter of 2025, based on the results of its CECL model and Management’s estimate of credit losses over the remaining life of its loans and debt securities held to maturity. During the nine months ended September 30, 2024, the Company provided $300 thousand for credit losses, which was recorded in the first quarter of 2024, based on the results of the CECL model and Management’s estimate of credit losses over the remaining life of its loans and debt securities held to maturity. Noninterest income in the nine months ended September 30, 2025 decreased $1.7 million compared with the nine months ended September 30, 2024 primarily because the nine months ended September 30, 2024 results included a $1.4 million gain on sale of other assets. Noninterest expense in the nine months ended September 30, 2025 decreased $2.1 million compared with the nine months ended September 30, 2024 primarily due to lower salaries and benefits and lower estimated operating losses from limited partnership investments, partially offset by higher outsourced data processing services expense and professional fees. The tax rate (FTE) was 26.2% for the nine months ended September 30, 2025 and 26.9% for the nine months ended September 30, 2024.

Net Interest and Loan Fee Income (FTE)

Following is a summary of the components of net interest and loan fee income (FTE) for the periods indicated:

($ in thousands)

Net interest and loan fee income (FTE) decreased $8.6 million in the three months ended September 30, 2025 compared with the three months ended September 30, 2024 due to lower average balances of investment securities (down $561 million) and loans (down $87 million), lower yield on investment securities (down 0.42%) and interest-bearing cash (down 0.98%), and higher rate on interest-bearing deposits (up 0.07%), partially offset by higher average balances of interest-bearing cash (up $208 million) and lower average balances of bank term funding program borrowings (down $167 million).

Net interest and loan fee income (FTE) decreased $27.9 million in the nine months ended September 30, 2025 compared with the nine months ended September 30, 2024 due to lower average balances of investment securities (down $657 million) and loans (down $76 million), lower yield on investment securities (down 0.47%) and interest-bearing cash (down 0.98%), and higher rate on interest-bearing deposits (up 0.13%), partially offset by higher average balances of interest-bearing cash (up $313 million) and lower average balances of bank term funding program borrowings (down $143 million).

The annualized net interest margin (FTE) was 3.80% in the three months ended September 30, 2025 and 3.85% in the nine months ended September 30, 2025 compared with 4.08% in the three months ended September 30, 2024 and 4.18% in the nine months ended September 30, 2024.

The Company’s funding costs were 0.26% in the three months ended September 30, 2025 and 0.24% in the nine months ended September 30, 2025 compared with 0.37% in the three months ended September 30, 2024 and 0.30% in the nine months ended September 30, 2024. Noninterest bearing deposits represented 46% of average deposits in the nine months ended September 30, 2025 and 48% in the nine months ended September 30, 2024. Average balances of checking and saving deposits accounted for 98% of average total deposits in the nine months ended September 30, 2025 and September 30, 2024.

Net Interest Margin (FTE)

The following summarizes the components of the Company's net interest margin (FTE) for the periods indicated (percentages are annualized.)

The Company’s yield on earning assets during the three months and nine months ended September 30, 2025 decreased compared with the three months and nine months ended September 30, 2024. The Company’s yield on earning assets has been primarily affected by collateralized loan obligations (CLOs), held in debt securities available for sale portfolio, and interest-bearing cash. The CLOs have interest coupons that change once every three months by the amount of change in the three-month SOFR base rate. The average balances and yields of CLOs for the three months ended September 30, 2025 was $659 million yielding 6.24% and $788 million yielding 6.25% for the nine months ended September 30, 2025. The average balances and yields of CLOs for the three and nine months ended September 30, 2024 were $1,166 million yielding 7.20% and $1,324 million yielding 7.22%, respectively. The interest-bearing cash yield changes by the amount of change in the overnight federal funds rate on the effective date declared by the FOMC. The average balance and yields of interest-bearing cash for the three months and nine months ended September 30, 2025 were $703 million yielding 4.37% and $656 million yielding 4.39%, respectively. The average balances and yields of interest-bearing cash for the three and nine months ended September 30, 2024 were $495 million yielding 5.35% and $342 million yielding 5.37%, respectively. The Company has other earning assets with variable yields such as commercial loans and lines of credit, consumer lines of credit and adjustable rate residential real estate loans, which are included in “other taxable loans” in the following “Summary of Average Balances, Yields/Rates and Interest Differential.”

Summary of Average Balances, Yields/Rates and Interest Differential

The following tables present information regarding the consolidated average assets, liabilities and shareholders’ equity, the amounts of interest income earned from average interest earning assets and the resulting yields, and the amounts of interest expense incurred on average interest-bearing liabilities and the resulting rates. Average loan balances include nonperforming loans. Interest income includes the reversal of previously accrued interest on loans placed on nonaccrual status during the period, proceeds from loans on nonaccrual status only to the extent cash payments have been received and applied as interest income, and accretion of purchased loan discounts. Yields, rates and interest margins are annualized. Yields on tax-exempt securities and loans have been adjusted upward to reflect the effect of income exempt from federal income taxation at the federal statutory tax rate of 21 percent.

Provision for Credit Losses

The Company manages credit risk by enforcing conservative underwriting and administration procedures and aggressively pursuing collection efforts with debtors experiencing financial difficulties. The provision for credit losses reflects Management's assessment of credit risk in the loan portfolio and debt securities held to maturity portfolio during each of the periods presented.

Based on Management’s estimate of credit losses over the remaining life of its loans and debt securities held to maturity, the Company provided no provision for credit losses in the three months ended September 30, 2025 and during the nine months ended September 30, 2025, the Company recorded a $550 thousand reversal of provision for credit losses, which was recored in the first quarter of 2025. The Company provided no provision for credit losses in the third quarter of 2024 based on Management’s estimate of credit losses over the remaining life of its loans and debt securities held to maturity. During the nine months ended September 30, 2024, the Company provided $300 thousand for credit losses, which was recorded in the first quarter of 2024. For further information regarding credit risk, net credit losses, and the allowance for credit losses, see the “Loan Portfolio Credit Risk” and “Allowance for Credit Losses” sections of this Report.

Noninterest Income

The following table summarizes the components of noninterest income for the periods indicated.

(In thousands)

Noninterest income for the three months ended September 30, 2025 decreased $1.8 million compared with the three months ended September 30, 2024 primarily due to lower income from service charges on deposits accounts and because the three months ended September 30, 2024 results included a $1.4 million gain on sale of other assets and a $202 thousand gain on bank owned life insurance. Higher income from merchant processing services partially offset the decrease in noninterest income for the three months ended September 30, 2025 compared with the three months ended September 30, 2024.

Noninterest income for the nine months ended September 30, 2025 decreased $1.7 million compared with the nine months ended September 30, 2024 primarily due to lower income from service charges on deposit accounts and ATM processing fees and because the nine months ended September 30, 2024 results included a $1.4 million gain on sale of other assets. The decrease in noninterest income was partially offset by higher income from merchant processing services and trust fees for the nine months ended September 30, 2025 compared with the nine months ended September 30, 2024.

Noninterest Expense

The following table summarizes the components of noninterest expense for the periods indicated.

(In thousands)

Noninterest expense for the three months ended September 30, 2025 decreased $509 thousand compared with the three months ended September 30, 2024 primarily due to lower salaries and benefits and lower estimated operating losses from limited partnership investments, partially offset by an increase in professional fees.

Noninterest expense for the nine months ended September 30, 2025 decreased $2.1 million compared with the nine months ended September 30, 2024 primarily due to lower salaries and benefits and lower estimated operating losses from limited partnership investments, partially offset by higher outsourced data processing services expense and professional fees.

Provision for Income Tax

The Company’s income tax provision (FTE) was $9.9 million and $31.3 million for the three and nine months ended September 30, 2025, respectively, compared with $13.0 million and $39.4 million for the three and nine months ended September 30, 2024, respectively. The effective tax rates (FTE) were 26.0% and 26.2%, for the three and nine months ended September 30, 2025, respectively, compared with 27.1% and 26.9% for the three and nine months ended September 30, 2024, respectively.

Investment Securities Portfolio

The Company maintains an investment securities portfolio consisting of securities issued by U.S. Treasury, U.S. Government sponsored entities, state and political subdivisions, corporations and banks. The Company had marketable equity securities held for trading at fair value of $436 thousand at September 30, 2025. The Company had no marketable equity securities not held for trading at September 30, 2025 and December 31, 2024.

Management manages the investment securities portfolio in response to anticipated changes in interest rates, and changes in deposit and loan volumes. The carrying value of the Company’s investment securities portfolio was $4.1 billion at September 30, 2025 and $4.2 billion at December 31, 2024. The following table lists debt securities in the Company’s portfolio by type as of the dates indicated. Debt securities held to maturity are listed at amortized cost before related reserve for expected credit losses of $1 thousand at September 30, 2025 and December 31, 2024. Debt securities available for sale are listed at fair value.

($ in thousands)

Management continually evaluates the Company’s investment securities portfolio in response to established asset/liability management objectives, changing market conditions that could affect profitability, liquidity, and the level of interest rate risk to which the Company is exposed. These evaluations may cause Management to change the level of funds the Company deploys into investment securities and change the composition of the Company’s investment securities portfolio.

At September 30, 2025, substantially all of the Company’s investment securities were investment grade as rated by one or more major rating agencies. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset-backed securities. The Company’s procedures for evaluating investments in securities are in accordance with guidance issued by the Board of Governors of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating Agencies” (SR 12-15) and other regulatory guidance.

The Company had corporate securities as shown below at the dates indicated:

Loan Portfolio Credit Risk

The Company extends loans to commercial and consumer customers which expose the Company to the risk that the borrowers will default, causing loss. The Company’s lending activities are exposed to various qualitative risks. All loan segments are exposed to risks inherent in the economy and market conditions. Significant risk characteristics related to the commercial loan segment include the borrowers’ business performance and financial condition, and the value of collateral for secured loans. Significant risk characteristics related to the commercial real estate segment include the borrowers’ business performance and the value of properties collateralizing the loans. Significant risk characteristics related to the construction loan segment include the borrowers’ performance in successfully developing the real estate into the intended purpose and the value of the property collateralizing the loans. Significant risk characteristics related to the residential real estate segment include the borrowers’ financial wherewithal to service the mortgages and the value of the property collateralizing the loans. Significant risk characteristics related to the consumer loan segment include the financial condition of the borrowers and the value of collateral securing the loans.

The Company closely monitors the markets in which it conducts its lending operations and follows a strategy to control exposure to loans with high credit risk. The Bank’s organizational structure separates the functions of business development and loan underwriting; Management believes this segregation of duties avoids inherent conflicts of combining business development and loan approval functions. In measuring and managing credit risk, the Company adheres to the following practices:

• The Bank maintains a Loan Review Department which reports directly to the audit committee of the Board of Directors. The Loan Review Department performs independent evaluations of loans to challenge the credit risk grades assigned by Management, using grading standards employed by bank regulatory agencies. Those loans judged to carry higher risk attributes are referred to as “classified loans.” Classified loans receive elevated Management attention in order to maximize collection.
• The Bank maintains two loan administration offices whose sole responsibility is to manage and collect classified loans.

Classified loans with higher levels of credit risk are further designated as “nonaccrual loans.” Management places classified loans on nonaccrual status when full collection of contractual interest and principal payments is in doubt. Uncollected interest previously accrued on loans placed on nonaccrual status is reversed as a charge against interest income. The Company does not accrue interest income on loans following placement on nonaccrual status. Interest payments received on nonaccrual loans are applied to reduce the carrying amount of the loan unless the carrying amount is well secured by loan collateral. “Nonperforming assets” include nonaccrual loans, loans 90 or more days past due and still accruing, and repossessed loan collateral (commonly referred to as “Other Real Estate Owned”).

Nonperforming Loans

(In thousands)

Management believes the overall credit quality of the loan portfolio is reasonably stable; however, classified and nonperforming assets could fluctuate from period to period. The performance of any individual loan can be affected by external factors such as the interest rate environment, economic conditions, pandemics, and collateral values or factors particular to the borrower. No assurance can be given that additional increases in nonaccrual and delinquent loans will not occur in the future.

Allowance for Credit Losses

The following table summarizes allowance for credit losses at the dates indicated:

(In thousands)

Allowance for Credit Losses on Debt Securities Held to Maturity

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 September 30, 2025, 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 September 30, 2025 and December 31, 2024, reflecting the expected credit losses on debt securities held to maturity.

Allowance for Credit Losses on Loans

The Company’s allowance for credit losses on loans represents Management’s estimate of forecasted credit losses in the loan portfolio based on the current expected credit loss model. In evaluating credit risk for loans, Management measures the loss potential of the carrying value of loans. As described above, payments received on nonaccrual loans may be applied against the principal balance of the loans until such time as full collection of the remaining recorded balance is expected.

The preparation of the financial statements requires Management to estimate the amount of expected losses over the expected contractual life of the Bank’s existing loan portfolio and establish an allowance for credit losses. Loan agreements generally include a maturity date, and the Company considers the contractual life of a loan agreement to extend from the date of origination to the contractual maturity date. In estimating credit losses, Management must exercise significant judgment in evaluating information deemed relevant. The amount of ultimate losses on the loan portfolio can vary from the estimated amounts. Management follows a systematic methodology to estimate loss potential in an effort to reduce the differences between estimated and actual losses.

The allowance for credit losses is established through provisions for credit losses charged to income. Losses on loans are charged to the allowance for credit losses when all or a portion of the recorded amount of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the allowance when realized. The Company’s allowance for credit losses 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 credit loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing economic conditions, or credit protection agreements and other factors.

Loans that share common risk characteristics are segregated into pools based on common characteristics, which is primarily determined by loan, borrower, or collateral type. Historical loss rates are determined for each pool. For consumer installment loans, primarily secured by automobiles, historical loss rates are determined using a vintage methodology, which tracks losses based on period of origination. For commercial, construction, and commercial real estate, historical loss rates are determined using an open pool methodology where losses are tracked over time for all loans included in the pool at the historical measurement date. Historical loss rates are adjusted for factors that are not reflected in the historical loss rates that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in past loan charge-off history, estimated losses based on management’s reasonable and supportable expectation of economic trends over a forecast horizon of up to two years, and other factors that impact credit loss expectations that are not reflected in the historical loss rates. Other factors include, but are not limited to, the effectiveness of the Company’s loan review system, adequacy of lending Management and staff, loan policies and procedures, problem loan trends, and concentrations of credit. At the end of the two-year forecast period loss rates revert immediately to the historical loss rates. The results of this analysis are applied to the amortized cost of the loans included within each pool.

Loans that do not share risk characteristics with other loans in the pools are evaluated individually. A loan is considered ‘collateral-dependent’ when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. A credit loss reserve for collateral-dependent loans is established at the difference between the amortized cost basis in the loan and the fair value of the underlying collateral adjusted for costs to sell. For other individually evaluated loans that are not collateral dependent, a credit loss reserve is established at the difference between the amortized cost basis in the loan and the present value of expected future cash flows discounted at the loan’s effective interest rate. The impact of an expected modification to be made to loans to borrowers experiencing financial difficulty is included in the allowance for credit losses when management determines such modification is likely.

Accrued interest is recorded in other assets and is excluded from the estimation of expected credit loss. Accrued interest is reversed through interest income when amounts are determined to be uncollectible, which generally occurs when the underlying receivable is placed on nonaccrual status or charged off.

The following table summarizes the allowance for credit losses, chargeoffs and recoveries for the periods indicated.

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.

Climate-Related Financial Risk

Climate change presents risk to the Company, our critical vendors and our customers. Our risk management practices incorporate the challenges brought about by climate change. The operations conducted in our centralized facilities and branch locations can be disrupted by acute physical risks such as flooding and windstorms, and by chronic physical risks such as rising sea levels, sustained higher temperatures, drought, and increased wildfires. Over the intermediate and longer-term, the Company can be subject to transition risks such as market demand, and policy and law changes.

None of the Company’s physical locations are located near sea level, and only a limited number of branches are located in flood zones. The Company and its critical vendors maintain property and casualty insurance, and maintain and regularly test disaster recovery plans, which include redundant operational locations and power sources. The Company’s operations do not use a significant amount of water in producing its products and services.

The Company monitors the climate risks of its loan customers. Borrowers with real estate loan collateral located in flood zones must carry flood insurance under the loans’ terms. At September 30, 2025, the Company had $16 million in loans to agricultural borrowers; Management continuously monitors these customers’ access to adequate water sources as well as their ability to sustain low crop yields and volatile commodity prices without encountering financial hardship. The Company makes automobile loans; changes in consumer demand, or governmental laws or policies, regarding gasoline, electric and hybrid vehicles are not considered to be material risks to the Company’s automobile lending practices. The Company considers climate risk in its underwriting of corporate bonds, and avoids purchasing bonds of issuers, which, in Management’s judgement, have elevated climate risk.

While the Company follows risk management practices related to climate risk, the Company may experience financial losses due to climate risk despite these precautions.

Asset/Liability and Market Risk Management

Asset/liability management involves the evaluation, monitoring and management of interest rate risk, market risk, liquidity and funding. The fundamental objective of the Company's management of assets and liabilities is to maximize its economic value while maintaining adequate liquidity and a conservative level of interest rate risk.

Interest Rate Risk

Interest rate risk is a significant market risk affecting the Company. Many factors affect the Company’s exposure to interest rates, such as general economic and financial conditions, customer preferences, historical pricing relationships, and re-pricing characteristics of financial instruments. Financial instruments may mature or re-price at different times. Financial instruments may re-price at the same time but by different amounts. Short-term and long-term market interest rates may change by different amounts. The timing and amount of cash flows of various financial instruments may change as interest rates change. In addition, the changing levels of interest rates may have an impact on bond portfolio volumes, accumulated other comprehensive (loss) income, loan demand and demand for various deposit products.

The Company’s earnings are affected not only by general economic conditions, but also by the monetary and fiscal policies of the United States government and its agencies, particularly the FOMC. The monetary policies of the FOMC can influence the overall demand for loans and growth of deposits and the level of interest rates earned on loans and investment securities and paid for deposits and other borrowings. The nature and impact of future changes in monetary policies are generally not predictable.

Management attempts to manage interest rate risk while enhancing the net interest margin and net interest income. At times, depending on expected increases or decreases in market interest rates, the relationship between long and short-term interest rates, market conditions and competitive factors, Management may adjust the Company's interest rate risk position. The Company's results of operations and net portfolio values remain subject to changes in interest rates and to fluctuations in the difference between long, intermediate, and short-term interest rates.

Management monitors the Company’s interest rate risk using a licensed 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.

The Company’s asset and liability position was generally “asset sensitive” at September 30, 2025, 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.

At September 30, 2025, Management’s most recent measurements of estimated changes in net interest income were:

(1) Balance sheet composition changes; Assumed change in interest rates over 1 year

(2) Balance sheet composition unchanged; Assumed immediate change in interest rates

Simulation estimates depend on, and will change with, the size and mix of the actual and projected composition of financial instruments at the time of each simulation. Assumptions made in the simulation may not materialize and unanticipated events and circumstances may occur. In addition, the simulation does not take into account any future actions Management may undertake to mitigate the impact of interest rate changes, loan prepayment estimates and spread relationships, which may change regularly.

The Company does not currently engage in trading activities or use derivative instruments to manage interest rate risk, even though such activities may be permitted with the approval of the Company's Board of Directors.

Market Risk - Equity Markets

Equity price risk can affect the Company. Preferred or common stock holdings, as permitted by banking regulations, can fluctuate in value. Changes in value of preferred or common stock holdings are recognized in the Company's income statement.

Fluctuations in the Company's common stock price can impact the Company's financial results in several ways. First, the Company has at times repurchased and retired its common stock; the market price paid to retire the Company's common stock affects the level of the Company's shareholders' equity, cash flows and shares outstanding. Second, the Company's common stock price impacts the number of dilutive equivalent shares used to compute diluted earnings per share. Third, fluctuations in the Company's common stock price can motivate holders of options to purchase Company common stock through the exercise of such options thereby increasing the number of shares outstanding and potentially adding volatility to the book tax provision. Finally, the amount of compensation expense and tax deductions associated with share based compensation fluctuates with changes in and the volatility of the Company's common stock price.

Market Risk - Other

Market values of loan collateral can directly impact the level of loan chargeoffs and the provision for credit losses. The financial condition and liquidity of debtors issuing bonds and debtors whose mortgages or other obligations are securitized can directly impact the credit quality of the Company’s investment securities portfolio requiring the Company to establish or increase reserves for expected credit losses. Other types of market risk, such as foreign currency exchange risk, are not significant in the normal course of the Company's business activities.

Liquidity and Funding

The objective of liquidity management is to manage cash flow and liquidity reserves so that they are adequate to fund the Bank's operations and meet obligations and other commitments on a timely basis and at a reasonable cost. The Bank achieves this objective through the selection of asset and liability maturity mixes that it believes best meet its needs. The Bank's liquidity position is enhanced by its ability to raise additional funds as needed by borrowing from correspondent banks or in the wholesale markets, or by selling debt securities available for sale.

In recent years, the Bank's deposit base has provided the majority of the Bank's funding requirements. This low-cost source of funds, along with shareholders' equity, provided 97% of funding for average total assets for the nine months ended September 30, 2025 and 96% for the year ended December 31, 2024. The Bank’s funding from customer deposits is in part reliant on the confidence clients have in the Bank. The Bank places a very high priority in maintaining this confidence through conservative credit risk and capital management practices and by maintaining an appropriate level of liquidity.

Total deposits were $4,793 million at September 30, 2025 and $5,012 million at December 31, 2024. Total time deposits were $71 million at September 30, 2025 and $82 million at December 31, 2024. The Company has no foreign time deposits. FDIC deposit insurance is $250,000 per depositor, for each account ownership category. At September 30, 2025, estimated federally uninsured total deposits and time deposits were $2,364 million and $4 million, respectively.

The following table shows the time remaining to maturity of the Company’s estimated amounts of uninsured time deposits with a balance greater than $250,000 per depositor per category:

Liquidity is further provided by assets such as balances held at the Federal Reserve Bank, and principal and interest payments from debt securities and loans. At September 30, 2025, the Company had $659,268 thousand in cash balances. During the twelve months ending September 30, 2026, the Company expects to receive $338,000 thousand in principal payments from its debt securities. If additional operational liquidity is required, the Company can pledge debt securities as collateral for borrowing purposes; at September 30, 2025, the Company’s debt securities which qualify as collateral for borrowing totaled $3,752,853 thousand. In the ordinary course of business, the Company pledges debt securities as collateral for certain depository customers; at September 30, 2025, the Company had pledged $713,200 thousand in debt securities for depository customers. In the ordinary course of business, the Company pledges debt securities as collateral for borrowing from the Federal Reserve Bank; at September 30, 2025, the Company had pledged $647,776 thousand in debt securities at the Federal Reserve Bank. During the nine months ended September 30, 2025, the Company’s average borrowings from the Federal Reserve Bank and other correspondent banks were $-0- thousand, respectively, and at September 30, 2025, the Company had no borrowings from the Federal Reserve Bank or other correspondent banks. At September 30, 2025, the Company had access to borrowing from the Federal Reserve Bank up to $647,776 thousand based on collateral pledged at September 30, 2025. At September 30, 2025, the Company’s estimated unpledged collateral qualifying debt securities totaled $1,970,022 thousand. Debt securities eligible as collateral are shown at market value unless noted otherwise:

Liquidity risk can result from the mismatching of asset and liability cash flows, or from disruptions in the financial markets. The Bank performs liquidity stress tests on a periodic basis to evaluate the sustainability of its liquidity. Under the stress testing, the Bank assumes outflows of funds increase beyond expected levels. Measurement of such heightened outflows considers the composition of the Bank’s deposit base, including any concentration of deposits, non-deposit funding such as short-term borrowings, and unfunded lending commitments. The composition of the Bank’s deposits is considered including the broad industry and geographic diversification in the Bank’s market area. The Bank evaluates its stock of highly liquid assets to meet the assumed higher levels of outflows. Highly liquid assets include cash and amounts due from other banks from daily transaction settlements, reduced by branch cash needs and any Federal Reserve Bank reserve requirements, and investment securities based on regulatory guidelines. Based on the results of the most recent liquidity stress test, Management is satisfied with the liquidity condition of the Bank. However, no assurance can be given the Bank will not experience a period of reduced liquidity.

Management continually monitors the Bank’s cash levels. Loan demand from credit worthy borrowers will be dictated by economic and competitive conditions. The Bank aggressively solicits non-interest bearing demand deposits and money market checking deposits, which are the least sensitive to changes in interest rates. The growth of these deposit balances is subject to heightened competition, the success of the Bank's sales efforts, delivery of superior customer service, new regulations and market conditions. The Bank does not aggressively solicit higher-costing time deposits. Changes in interest rates, most notably rising or elevated interest rates, or increased consumer spending, could impact deposit volumes. Depending on economic conditions, interest rate levels, liquidity management and a variety of other conditions, any deposit growth may be used to fund loans or purchase investment securities. However, due to possible volatility in economic conditions, competition and political uncertainty, loan demand and levels of customer deposits are not certain. Shareholder dividends are expected to continue subject to the Board's discretion and continuing evaluation of capital levels, earnings, asset quality and other factors.

Westamerica Bancorporation ("Parent Company") is a separate entity apart from the Bank and must provide for its own liquidity. In addition to its operating expenses, the Parent Company is responsible for the payment of dividends declared for its shareholders, and interest and principal on any outstanding debt. The Parent Company had no debt at September 30, 2025. Substantially all of the Parent Company's revenues are obtained from subsidiary dividends and service fees.

The Bank’s dividends paid to the Parent Company and Parent Company cash balances provided adequate cash for the Parent Company to pay shareholder dividends of $35 million in the nine months ended September 30, 2025 and $47 million in the year ended December 31, 2024 and retire common stock in the amounts of $80 million in the nine months ended September 30, 2025 and $210 thousand in the year ended December 31, 2024. Payment of dividends to the Parent Company by the Bank is limited under California and Federal laws. The Company believes these regulatory dividend restrictions will not impact Parent Company's ability to meet its ongoing cash obligations. The Parent Company’s cash balance was $265 million at September 30, 2025 and $263 million at December 31, 2024.

Capital Resources

The Company has historically generated high levels of earnings, which provide a means of accumulating capital. The Company's net income as a percentage of average shareholders' equity (“return on equity” or “ROE”) was 11.4% (annualized) for the nine months ended September 30, 2025 and 13.8% for the year ended December 31, 2024. The Company also raises capital as employees exercise stock options. The Company raised $376 thousand through the exercise of stock options in the nine months ended September 30, 2025 while $1.5 million was raised through the exercise of stock options in the year ended December 31, 2024.

The Company paid cash dividends on its common stock totaling $35 million in the nine months ended September 30, 2025 and $47 million in the year ended December 31, 2024, which represent dividends per common share of $1.36 and $1.76, respectively. The Company's earnings have historically exceeded dividends paid to shareholders. The amount of earnings in excess of dividends provides the Company resources to finance growth and maintain appropriate levels of shareholders' equity. In the absence of profitable growth opportunities, the Company has at times repurchased and retired its common stock as another means to return capital to shareholders. The Company retired 1.6 million shares valued at $80 million in the nine months ended September 30, 2025 and 4 thousand shares valued at $210 thousand in the year ended December 31, 2024.

The Company's primary capital resource is shareholders' equity, which was $932 million at September 30, 2025 compared with $890 million at December 31, 2024. The Company's ratio of equity to total assets was 15.75% at September 30, 2025 and 14.65% at December 31, 2024.

The Company performs capital stress tests on a periodic basis to evaluate the sustainability of its capital. Under the stress testing, the Company assumes various scenarios such as deteriorating economic and operating conditions, and unanticipated asset devaluations. The Company measures the impact of these scenarios on its earnings and capital. Based on the results of the most recent stress tests, Management is satisfied with the capital condition of the Bank and the Company. However, no assurance can be given the Bank or Company will not experience a period of reduced earnings or a reduction in capital from unanticipated events and circumstances.

Capital to Risk-Adjusted Assets

The capital ratios for the Company and the Bank under current regulatory capital standards are presented in the tables below, on the dates indicated. For Common Equity Tier I Capital, Tier 1 Capital and Total Capital, the minimum percentage required for regulatory capital adequacy purposes include a 2.5% “capital conservation buffer.”

The Company and the Bank routinely project capital levels by analyzing forecasted earnings, credit quality, shareholder dividends, asset volumes, share repurchase activity, stock option exercise proceeds, and other factors. Based on current capital projections, the Bank expects to maintain regulatory capital levels in excess of the minimum required to be considered well-capitalized under the prompt corrective action framework. The Company expects to continue paying quarterly dividends to shareholders. No assurance can be given that changes in capital management plans will not occur.

The Company does not currently engage in trading activities or use derivative instruments to control interest rate risk, even though such activities may be permitted with the approval of the Company’s Board of Directors.

Credit risk and interest rate risk are the most significant market risks affecting the Company, and equity price risk can also affect the Company’s financial results. These risks are described in the preceding sections regarding “Loan Portfolio Credit Risk,” and “Asset/Liability and Market Risk Management.” Other types of market risk, such as foreign currency exchange risk and commodity price risk, are not significant in the normal course of the Company’s business activities.

Operational risk is the risk to current or projected financial condition and resilience arising from inadequate or failed internal processes or systems, people (including human errors or misconduct), or adverse external events, including the risk of loss resulting from breaches in data security. Operational risk can also include the risk of loss due to failures by third parties with which the Company does business.

The Company’s principal executive officer and principal financial officer have evaluated the effectiveness of the Company’s “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, as of September 30, 2025.

Based upon their evaluation, the principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures are effective to ensure that material information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported as and when required and that such information is communicated to the Company’s management, including the principal executive officer and the principal financial officer, to allow for timely decisions regarding required disclosures. The evaluation did not identify any change in the Company’s internal control over financial reporting that occurred during the quarter ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company’s Annual Report on Form 10-K for the year ended December 31, 2024 includes detailed disclosure about the risks faced by the Company’s business.
