Item 9A. Controls and Procedures Attached as Exhibits 31.1 and 31.2 to this Annual Report on Form 10-K are certifications of ADP's Chief Executive Officer and Chief Financial Officer, which are required by Rule 13a-14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This “Controls and Procedures” section should be read in conjunction with the report of Deloitte & Touche LLP that appears in this Annual Report on Form 10-K and is hereby incorporated herein by reference. Management's Evaluation of Disclosure Controls and Procedures The Company carried out an evaluation (the “evaluation”), under the supervision and with the participation of the Company's management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of June 30, 2025 in ensuring that (i) information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure and (ii) such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Management's Report on Internal Control over Financial Reporting It is the responsibility of Automatic Data Processing, Inc.'s (“ADP”) management to establish and maintain effective internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Internal control over financial reporting is designed to provide reasonable assurance to ADP's management and board of directors regarding the preparation of reliable financial statements for external purposes in accordance with generally accepted accounting principles. ADP's internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of ADP; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of ADP are being made only in accordance with authorizations of management and directors of ADP; and (iii) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use or disposition of ADP's assets that could have a material effect on the financial statements of ADP. 83 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Management has performed an assessment of the effectiveness of ADP’s internal control over financial reporting as of June 30, 2025 based upon criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management determined that ADP’s internal control over financial reporting was effective as of June 30, 2025. Deloitte & Touche LLP, the independent registered public accounting firm that audited and reported on the consolidated financial statements of ADP included in this Annual Report on Form 10-K, has issued an attestation report on the operating effectiveness of ADP's internal control over financial reporting. The Deloitte & Touche LLP attestation report is set forth below. /s/ Maria Black Maria Black Chief Executive Officer /s/ Peter Hadley Peter Hadley Chief Financial Officer Roseland, New Jersey August 6, 2025 84 Changes in Internal Control over Financial Reporting There were no changes in ADP's internal control over financial reporting that occurred during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, ADP's internal control over financial reporting. 85 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of Automatic Data Processing, Inc. Roseland, New Jersey Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Automatic Data Processing, Inc. and subsidiaries (the “Company”) as of June 30, 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 Company maintained, in all material respects, effective internal control over financial reporting as of June 30, 2025 , based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended June 30, 2025 , of the Company and our report dated August 6, 2025, expressed an unqualified opinion on those financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 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 obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Deloitte & Touche LLP Morristown, New Jersey August 6, 2025 86 Item 9B.
