Inour opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan at December31, 2025 and 2024, and the changes in its net assets available for benefits for the years then ended, in conformity with U.S. generallyaccepted accounting principles. Basis for Opinion These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’sfinancial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting OversightBoard (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federalsecurities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the auditto 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 ofour audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressingan opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due toerror or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidenceregarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles usedand significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believethat our audits provide a reasonable basis for our opinion.
