Copyright © 2021 ADP, Inc. 33 Forward Looking Statements This presentation and other written or oral statements made from time to time by ADP may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Statements that are not historical in nature and which may be identified by the use of words like “expects,” “assumes,” “projects,” “anticipates,” “estimates,” “we believe,” “could” “is designed to” and other words of similar meaning, are forward-looking statements. These statements are based on management’s expectations and assumptions and depend upon or refer to future events or conditions and are subject to risks and uncertainties that may cause actual results to differ materially from those expressed. Factors that could cause actual results to differ materially from those contemplated by the forward-looking statements or that could contribute to such difference include: ADP's success in obtaining and retaining clients, and selling additional services to clients; the pricing of products and services; the success of our new solutions; compliance with existing or new legislation or regulations; changes in, or interpretations of, existing legislation or regulations; overall market, political and economic conditions, including interest rate and foreign currency trends and inflation; competitive conditions; our ability to maintain our current credit ratings and the impact on our funding costs and profitability; security or cyber breaches, fraudulent acts, and system interruptions and failures; employment and wage levels; changes in technology; availability of skilled technical associates; the impact of new acquisitions and divestitures; the adequacy, effectiveness and success of our business transformation initiatives; and the impact of any uncertainties related to major natural disasters or catastrophic events, including the coronavirus (“COVID-19”) pandemic. ADP disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. These risks and uncertainties, along with the risk factors discussed under “Item 1A. Risk Factors” of our most recent Annual Report on Form 10-K and in other written or oral statements made from time to time by ADP, should be considered in evaluating any forward-looking statements contained herein. Note Regarding the Use of Non-GAAP Financial Metrics This presentation contains non-GAAP financial metrics. Please refer to the accompanying financial tables in the Appendix for a discussion and reconciliation of non-GAAP financial metrics to their closest comparable GAAP financial metrics. Adjusted EBIT margin, organic constant currency, and adjusted diluted earnings per share are non-GAAP financial measures. We have not provided a reconciliation of our adjusted EBIT margin outlook, organic constant currency outlook or adjusted EPS outlook to their most comparable GAAP measures for such years because it would be potentially misleading and not practical given the difficulty of projecting event-driven transactional and other non-core operating items that are included in the GAAP metrics, including gains/losses on sales of businesses and assets and certain income tax adjustments. The accompanying reconciliation for the historical period presented is indicative of the reconciliation that will be prepared upon completion of the periods covered by the non-GAAP outlook.

Copyright © 2021 ADP, Inc. 65 Non-GAAP Financial Metrics In addition to our GAAP results, we use the adjusted results and other non-GAAP metrics set forth in the table below to evaluate our operating performance in the absence of certain items and for planning and forecasting of future periods: We believe that the exclusion of the identified items below helps us reflect the fundamentals of our underlying business model and analyze results against our expectations and against prior period, and to plan for future periods by focusing on our underlying operations. We believe that the adjusted results provide relevant and useful information for investors because it allows investors to view performance in a manner similar to the method used by management and improves their ability to understand and assess our operating performance. The nature of these exclusions is for specific items that are not fundamental to our underlying business operations. Since these adjusted financial measures and other non-GAAP metrics are not measures of performance calculated in accordance with U.S. GAAP, they should not be considered in isolation from, as a substitute for, or superior to their corresponding U.S. GAAP measures, and they may not be comparable to similarly titled measures at other companies.
