In our opinion, the 2025financial statements present fairly, in all material respects, the net assets available forbenefits of the Plan as of December 31, 2025, and the changes in net assets available for benefits for the year then ended, in conformity withaccounting principles generally accepted in the United States of America. Basis for Opinion Thesefinancial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s 2025financialstatements based on our audit. We are a public accountingfirm registered with the Public Company Accounting Oversight Board (United States)(“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rulesand regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtainreasonable assurance about whether the 2025financial statements are free of material misstatement, whether due to error or fraud. The Plan isnot required to have, nor were we engaged to perform, an audit of its internal control overfinancial reporting. As part of our audit, we are requiredto obtain an understanding of internal control overfinancial reporting but not for the purpose of expressing an opinion on the effectiveness of thePlan’s internal control overfinancial reporting. Accordingly, we express no such opinion. Our audit included performing procedures to assess the risks of material misstatement of the 2025financial statements, whether due to error orfraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amountsand disclosures in the 2025financial statements. Our audit also included evaluating the accounting principles used and significant estimates madeby the Plan’s management, as well as evaluating the overall presentation of the 2025financial statements.
