<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">We have audited the accompanying statements of net assets available for
benefits of Westamerica Bancorporation Tax Deferred Savings/Retirement Plan (ESOP) (the &quot;Plan&quot;) as of December 31, 2024 and
2023, the related statements of changes in net assets available for benefits for the years then ended, and the related notes (collectively
referred to as the &quot;financial statements&quot;). In our opinion, the financial statements present fairly, in all material respects,
the net assets available for benefits of the Plan as of December 31, 2024 and 2023, and the changes in net assets available for benefits
for the years then ended, in conformity with accounting principles generally accepted in the United States of America.</P>

<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">These financial statements are the responsibility of the Plan's management.
Our responsibility is to express an opinion on the Plan's financial statements based on our audits. We are a public accounting firm registered
with the Public Company Accounting Oversight Board (United States) (&quot;PCAOB&quot;) and are required to be independent with respect
to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange
Commission and the PCAOB.</P>

<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">&nbsp;</P>

<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">We conducted our audits in accordance with the standards of the PCAOB.
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free
of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over
financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan&rsquo;s internal control over financial
reporting. Accordingly, we express no such opinion.</P>

<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">&nbsp;</P>

<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation
of the financial statements. We believe that our audits provide a reasonable basis for our opinion.</P>

<P STYLE="font-size: 10pt; text-align: justify; margin: 0pt 0">The supplemental Schedule H, Line 4a &ndash; Schedule of Delinquent Participant
Contributions for the year ended December 31, 2024 and Schedule H, Line 4i &ndash; Schedule of Assets (Held at End of Year) as of December
31, 2024 have been subjected to audit procedures performed in conjunction with the audit of Westamerica Bancorporation Tax Deferred Savings/Retirement
Plan (ESOP) financial statements. The supplemental schedules are the responsibility of the Plan&rsquo;s management. Our audit procedures
included determining whether the information presented in the supplemental schedules reconciles to the financial statements or the underlying
accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented
in the supplemental schedules. In forming our opinion on the supplemental schedules, we evaluated whether the supplemental schedules,
including their form and content, are presented in conformity with the Department of Labor&rsquo;s Rules and Regulations for Reporting
and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental schedules are fairly stated
in all material respects in relation to the financial statements as a whole.</P>

Plan for an asset or paid by the Plan to transfer a liability (an exit price) in an orderly transaction between market participants on
the measurement date in the Plan's principal or most advantageous market for the asset or liability. Fair value measurements are determined
by maximizing the use of available observable inputs and minimizing the use of available unobservable inputs. The fair value hierarchy
places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (level 1 measurements)
and gives the lowest priority to unobservable inputs (level 3 measurements). The three levels of inputs within the fair value hierarchy
are defined as follows:</P>

close of regular market trading (Level 1 inputs). The NAV is a quoted price in a market that is active.</P>
