AI is adding new layers of complexity to our clients' work, and we are well into building the capabilities to meet that moment. We are primed to capture and harness the significant opportunity ahead for the HCM industry."

“Our third quarter results came in ahead of our expectations across revenue growth, adjusted EBIT margin, and adjusted EPS," said Peter Hadley, Chief Financial Officer, ADP. “ADP has the financial strength and scale to invest with confidence in AI capabilities across our products, service delivery, and sales organization to fuel our future growth, while continuing to deliver on our financial commitments. Our updated fiscal 2026 guidance reflects stronger revenue and earnings growth."

Adjusted EBIT, adjusted EBIT margin, adjusted net earnings, adjusted diluted earnings per share, adjusted effective tax rate and organic constant currency are all non-GAAP financial measures.

The Fed Funds futures contracts are used in the client short and corporate cash interest income outlook. A combination of various forward yield curves that reflect our investment mix, resulting in a blended rate of 3.9%, was used to forecast new purchase rates across the client and corporate extended and client long portfolios over the remainder of the fiscal year.

•Interest on funds held for clients of $1.340 to $1.350 billion; this is based on anticipated growth in client funds balances of about 6% and an average yield that is anticipated to increase approximately 3.4%

(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)

(Unaudited)

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:

Adjusted Financial Measures

U.S. GAAP Measures

Adjusted EBIT Net earnings

Adjusted provision for income taxes Provision for income taxes

Adjusted net earnings Net earnings

Adjusted diluted earnings per share Diluted earnings per share

Adjusted effective tax rate Effective tax rate

Organic constant currency Revenues

Corporate extended interest income (see prior page)

Interest income

Short-term financing to Support Client Funds Extended Strategy (see prior page)

Interest expense

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 a partial reversal of the workforce optimization initiative from fiscal 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, this specific reversal relates to a broad-based, company-wide initiative.

(c) 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.

(d) In the nine months ended March 31, 2025, this represents a reversal of a legal reserve recorded during the year ended June 30, 2023.

(e) The income tax provision was calculated based on the annualized marginal rate in effect during the quarter of the adjustment.

(f) 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.
