Opinions on the Financial Statements and Internal Control over Financial Reporting

 

We have audited the accompanying consolidated balance sheets of Paychex, Inc. and its subsidiaries (the "Company") as of May 31, 2025 and 2024, and the related consolidated statements of income and comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended May 31, 2025, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of May 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of May 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended May 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of May 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
