(A) We utilize a strategy by which we extend the maturities of our investment portfolio for funds held for clients and employ short-term financing arrangements to satisfy our short-term funding requirements related to client funds obligations. As part of our client funds investment strategy, we use daily collection of funds from our clients to satisfy other unrelated client funds obligations, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities.

(B) While “Corporate extended interest income” and “Short-term financing to support Client Funds Strategy,” related to our client funds investment strategy, are non-GAAP measures, management believes this information is beneficial to reviewing the financial statements of ADP. Management believes this information is beneficial as it allows the reader to understand the extended investment strategy for ADP's client funds assets, corporate investments, and short-term borrowings.

Consolidated Statement of Adjusted / Non-GAAP Financial Information

(in millions, except per share amounts)

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 periods, 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.

(a) In adjusted EBIT, we include the interest income earned on investments associated with our client funds extended investment strategy and interest expense on borrowings related to our client funds extended investment strategy as we believe these amounts to be fundamental to the underlying operations of our business model. The adjustments in the table above represent the interest income and interest expense that are not related to our client funds extended investment strategy and are labeled as “All other interest expense” and “All other interest income.”

(b) Represents partial reversals of workforce optimization initiatives from fiscal 2025 and 2024. Severance charges/(reversals) have been taken in the past and not included as an adjustment to get to adjusted results. Unlike severance charges/(reversals) in prior periods, these specific reversals relate to broad-based, company-wide initiatives.

(c) In Q4 2026, we incurred a charge of $91.1 million as part of a corporate-led business alignment program, which is designed to better align our organization and resources with our Strategic Priorities and to streamline the organizational structure. Costs associated with this program included severance costs of $89.1 million and strategic project costs of $2.0 million. Strategic project costs consist primarily of external advisory costs. This charge is excluded from adjusted net earnings to provide a clearer view of ongoing operations and enhance period-over-period comparability. Severance charges have been taken in the past and not included as an adjustment to get to adjusted results. Unlike charges in prior periods, these specific charges relate to a broad-based, company-wide initiative.

(d) Represents (gains)/losses on investments made through our Corporate Venture Capital arm, ADP Ventures. (Gains)/losses on these investments may result from observable price changes, changes in ownership interest, accrued interest income, and impairment charges. These adjustments may be highly variable, are predominantly non-cash, are outside our control, and are not fundamental to the underlying operations of our business model.

(e) In fiscal 2026, this represents a net charge (reserve and insurance recovery) from a legal matter settled during the year ended June 30, 2026. In fiscal 2025, this represents a reversal of a legal reserve recorded during the year ended June 30, 2023.

(f) The income tax provision was calculated based on the marginal rate in effect during the period of the adjustment.

(g) The adjusted effective tax rate is calculated as our adjusted provision for income taxes divided by the sum of our adjusted net earnings plus our adjusted provision for income taxes.

The following table reconciles our reported growth rates to the non-GAAP measure of organic constant currency, which excludes the impact of acquisitions, the impact of dispositions, and the impact of foreign currency. The impact of acquisitions and dispositions is calculated by excluding the current year revenues of acquisitions until the one-year anniversary of the transaction and by excluding the prior year revenues of divestitures for the one-year period preceding the transaction. The impact of foreign currency is determined by calculating the current year results using foreign exchange rates consistent with the prior year. The PEO segment is not impacted by acquisitions, dispositions or foreign currency.

(a) In Adjusted EBIT, we include the interest income earned on investments associated with our client funds extended investment strategy and interest expense on borrowings related to our client funds extended investment strategy as we believe these amounts to be fundamental to the underlying operations of our business model. The adjustments in the table above represent the interest income and interest expense that are not related to our client funds extended investment strategy and are labeled as “All other interest expense” and “All other interest income.”
