DISCLAIMERS FORWARD-LOOKING STATEMENTS This document 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 “outlook,” “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; our ability to respond successfully to changes in technology, including artificial intelligence; 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; availability of skilled associates; the impact of new acquisitions and divestitures; the adequacy, effectiveness and success of our business transformation initiatives; the impact of any uncertainties related to major natural disasters or catastrophic events; and supply-chain disruptions. 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. This presentation contains non-GAAP financial metrics, including Adjusted EBIT margin and adjusted diluted earnings per share. For a discussion and reconciliation of historic non-GAAP financial metrics to their closest comparable GAAP financial metrics, see our earnings releases for the applicable periods presented, available at adp.investors.com or sec.gov. We have not provided a reconciliation of our revenue outlook (in organic constant currency), adjusted EBIT margin outlook or adjusted earnings per share 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 or 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 reconciliations provided in earnings releases prepared by ADP are indicative of the reconciliation that will be prepared upon completion of the periods covered by the non-GAAP medium-term objectives.
