Notes to the Consolidated Financial Statements
(Tabular dollars in millions, except per share amounts or where otherwise stated)
(Unaudited)
Note 1.  Basis of Presentation

The accompanying Consolidated Financial Statements and footnotes thereto of Automatic Data Processing, Inc., its subsidiaries and variable interest entity (“ADP” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Consolidated Financial Statements and footnotes thereto are unaudited. In the opinion of the Company’s management, the Consolidated Financial Statements reflect all adjustments, which are of a normal recurring nature, that are necessary for a fair presentation of the Company’s interim financial results.

The Company has a grantor trust, which holds the majority of the funds provided by its clients pending remittance to employees of those clients, tax authorities, and other payees. The Company is the sole beneficial owner of the trust. The trust meets the criteria in Accounting Standards Codification (“ASC”) 810, “Consolidation” to be characterized as a variable interest entity (“VIE”). The Company has determined that it has a controlling financial interest in the trust because it has both (1) the power to direct the activities that most significantly impact the economic performance of the trust (including the power to make all investment decisions for the trust) and (2) the right to receive benefits that could potentially be significant to the trust (in the form of investment returns) and, therefore, consolidates the trust. Further information on these funds and the Company’s obligations to remit to its clients’ employees, tax authorities, and other payees is provided in Note 7, “Corporate Investments and Funds Held for Clients.” 

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the assets, liabilities, revenue, expenses, and accumulated other comprehensive income that are reported in the Consolidated Financial Statements and footnotes thereto. Actual results may differ from those estimates. Interim financial results are not necessarily indicative of financial results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2024 (“fiscal 2024”). Certain amounts from the prior year's financial statements have been reclassified in order to conform to the current year's presentation.

Note 3.  Revenue

Based upon similar operational and economic characteristics, the Company’s revenues are disaggregated by its three business pillars: Human Capital Management (“HCM”), HR Outsourcing (“HRO”), and Global Solutions (“Global”), with separate disaggregation for PEO zero-margin benefits pass-through revenues and client funds interest revenues. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors.

The following tables provide details of revenue by our business pillars, and include a reconciliation to the Company’s reportable segments:

Contract Balances

The timing of revenue recognition for HCM, HRO and Global is consistent with the invoicing of clients, as invoicing occurs in the period the services are provided. Therefore, the Company does not recognize a contract asset or liability resulting from the timing of revenue recognition and invoicing.

Changes in deferred revenues related to set up fees for the six months ended December 31, 2024 were as follows:
Contract Liability
Contract liability, July 1, 2024$491.6 
Recognition of revenue included in beginning of year contract liability(69.9)
Contract liability, net of revenue recognized on contracts during the period60.9 
Currency translation adjustments(10.8)
Contract liability, December 31, 2024$471.8 

Note 4. Acquisition

In October 2024, the Company acquired WorkForce Software, a premier workforce management solutions provider that specializes in supporting large, global enterprises, utilizing cash on hand. The results of WorkForce Software will be reported within the Company’s Employer Services segment. Pro forma information has not been presented because the effect of the acquisition is not material to the Company's consolidated financial results.

The following table reconciles the purchase price to the cash paid for the acquisition, net of cash acquired:
Purchase price$1,173.1 
Less: cash acquired(12.5)
Cash paid for acquisition of business, net of cash acquired$1,160.6 

The preliminary allocation of the purchase price is based upon estimates and assumptions that are subject to change within the measurement period, which is one year from the acquisition date. The primary areas of the purchase price allocation that are not yet finalized relate to the measurement of certain assets and liabilities, including identifiable intangible assets, and the finalization of net working capital items included in the purchase price allocation. Accordingly, the measurement period for such purchase price allocations will end when the information becomes available but will not exceed twelve months from the date of acquisition.

The acquisition was accounted for using the acquisition method of accounting. The Company recognized assets acquired and liabilities assumed at their fair value as of the date of acquisition, with the excess recorded to goodwill. The preliminary purchase price allocation for WorkForce Software is as follows:
9


Cash$12.5 
Accounts receivable, net of allowance for doubtful accounts20.0 
Identifiable intangible assets (1)417.0 
Goodwill846.4 
All other assets21.9 
Total assets acquired$1,317.8 
Deferred revenue$39.6 
Deferred income taxes46.6 
All other liabilities58.5 
Total liabilities assumed$144.7 
Total net assets acquired$1,173.1 

(1) Intangible assets are recorded at estimated fair value, as determined by management based on available information which includes an estimated valuation by an independent third-party. The fair values assigned to identifiable intangible assets were determined through the use of the income approach, specifically the relief from royalty and the multi-period excess earnings methods. The major assumptions used in arriving at the estimated identifiable intangible asset values included management’s estimates of future cash flows, discounted at an appropriate rate of return which are based on the weighted average cost of capital for both the Company and other market participants, projected customer attrition rates, as well as applicable royalty rates for comparable assets. The useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to the future cash flows. The estimated fair value of intangible assets and related useful lives as included in the estimated purchase price allocation include:

Estimated Fair ValueEstimated Useful Life
(in years)
Technology$200.0 7
Customer/Partner relationships$210.0 8
Tradename$7.0 4

The goodwill recorded as a result of the WorkForce Software transaction represents future economic benefits the Company expects to achieve as a result of the acquisition, including expected synergies along with the value of the assembled workforce. None of the goodwill resulting from the acquisition is tax deductible.

Note 8.  Leases

The Company records leases on the Consolidated Balance Sheets as operating lease right-of-use (“ROU”) assets, records the current portion of operating lease liabilities within accrued expenses and other current liabilities and, separately, records long-term operating lease liabilities. The difference between total ROU assets and total lease liabilities is primarily attributable to prepayments of our obligations and the recognition of various lease incentives.

The Company has entered into operating lease agreements for facilities and equipment. The Company's leases have remaining lease terms of up to approximately eleven years.

The components of operating lease expense were as follows:

Note 10. Short-term Financing

The Company has a $4.55 billion, 364-day credit agreement that matures in June 2025 with a one year term-out option. The Company also has a $2.25 billion, five year credit facility that matures in June 2028 that contains an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. In addition, the Company also has a five year, $3.5 billion credit facility maturing in June 2029 that contains an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. The interest rate applicable to committed borrowings is tied to SOFR, the effective federal funds rate, or the prime rate depending on the notification provided by the Company to the syndicated financial institutions prior to borrowing. The Company is also required to pay facility fees on the credit agreements. The primary uses of the credit facilities are to provide liquidity to the commercial paper program and funding for general corporate purposes, if necessary. The Company had no borrowings through December 31, 2024 under the credit agreements.

The Company's U.S. short-term funding requirements related to client funds are sometimes obtained on an unsecured basis through the issuance of commercial paper, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. This commercial paper program provides for the issuance of up to $10.3 billion in aggregate maturity value. The Company’s commercial paper program is rated A-1+ by Standard & Poor’s, Prime-1 (“P-1”) by Moody’s and F1+ by Fitch. These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At December 31, 2024 and June 30, 2024, the Company had no commercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

Weighted average maturity (approximately in days)2 days2 days2 days2 days

The Company’s U.S., Canadian and United Kingdom short-term funding requirements related to client funds obligations are sometimes obtained on a secured basis through the use of reverse repurchase agreements, which are collateralized principally by government and government agency securities, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. These agreements generally have terms ranging from overnight to up to five business days. At December 31, 2024, the Company had no outstanding obligations related to reverse repurchase agreements. At June 30, 2024, the Company had $385.4 million of outstanding obligations related to reverse repurchase agreements which were fully paid in early July 2024. The Company has $7.3 billion available on a committed basis under the U.S. reverse repurchase agreements. Details of the reverse repurchase agreements are as follows:

Note 11. Debt

The Company issued four series of fixed-rate notes with staggered maturities of 7 and 10 years totaling $4.0 billion (collectively the “Notes”). The Notes are senior unsecured obligations, and interest is payable in arrears, semi-annually.
During the first quarter ended September 30, 2024, the Company issued $1.0 billion of senior notes due in 2034 bearing a fixed interest rate of 4.450%. In connection with the senior notes issuance, the Company terminated several derivative contracts in place to hedge exposure in changes in benchmark interest rates for the senior notes issued with an aggregate notional amount totaling $1.0 billion (of which $400.0 million were executed during the three months ended September 30, 2024 and $600.0 million were executed on the day of issuance). Since these derivative contracts were classified as cash flow hedges, the unamortized loss of $12.5 million was deferred in accumulated other comprehensive income and will be amortized to earnings over the life of the issued Notes as the interest payments are made.
The principal amounts and associated effective interest rates of the Notes and other debt as of December 31, 2024 and June 30, 2024, are as follows:
Debt instrumentEffective Interest RateDecember 31, 2024June 30, 2024

Total long-term debt$2,982.0 $2,991.3 
The effective interest rates for the Notes include the interest on the Notes and amortization of the discount and debt issuance costs.

As of December 31, 2024, the fair value of the Notes, based on Level 2 inputs, was $3,688.6 million. For a description of the fair value hierarchy and the Company's fair value methodologies, including the use of an independent third-party pricing service, see Note 1 “Summary of Significant Accounting Policies” in the Company's Annual Report on Form 10-K for fiscal 2024.

Note 12. Employee Benefit Plans

A.  Stock-based Compensation Plans

The Company's share-based compensation consists of stock options, time-based restricted stock, time-based restricted stock units, performance-based restricted stock, and performance-based restricted stock units. The Company also offers an employee stock purchase plan for eligible employees. Beginning in September 2022, the Company discontinued granting stock options, time-based restricted stock and performance-based restricted stock. Any such future awards will be grants of time-based restricted stock units and/or performance-based restricted stock units, depending on employee eligibility. Time-based restricted stock unit awards and performance-based restricted stock unit awards granted to employees with a home country of the United States are settled in stock, and for awards granted to employees with a home country outside the United States are generally settled in cash.

The Company currently utilizes treasury stock to satisfy stock option exercises, issuances under the Company's employee stock purchase plan, and restricted stock units. From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase program. The Company repurchased 0.9 million and 1.1 million shares in the three months ended December 31, 2024 and 2023, respectively, and repurchased 2.4 million and 2.1 million shares in the six months ended December 31, 2024 and 2023. The Company considers several factors in determining when to execute share repurchases, including, among other things, actual and potential acquisition activity, cash balances and cash flows, issuances due to employee benefit plan activity, and market conditions.

Note 13. Income Taxes

The effective tax rate for the three months ended December 31, 2024 and 2023 was 23.6% and 23.2%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities in the three months ended December 31, 2023, partially offset by a higher excess tax benefit on stock-based compensation in the three months ended December 31, 2024.

The effective tax rate for the six months ended December 31, 2024 and 2023 was 23.1% and 22.3%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities, lower reserves for uncertain tax positions and a valuation allowance release in the six months ended December 31, 2023.

Note 14. Commitments and Contingencies

In May 2020, a putative class action complaint was filed against ADP, TotalSource and related defendants in the U.S. District Court, District of New Jersey. The complaint asserts violations of the Employee Retirement Income Security Act of 1974 (“ERISA”) in connection with the ADP TotalSource Retirement Savings Plan’s fiduciary administrative and investment decision-making. The complaint seeks statutory and other unspecified monetary damages, injunctive relief and attorney’s fees. The Company is unable to estimate any reasonably possible loss, or range of loss, with respect to this matter. The Company is vigorously defending against this lawsuit.

The Company is subject to various claims, litigation, and regulatory compliance matters in the normal course of business. When a loss is considered probable and reasonably estimable, the Company records a liability in the amount of its best estimate for the ultimate loss. Management currently believes that the resolution of these claims, litigation and regulatory compliance matters against us, individually or in the aggregate, will not have a material adverse impact on our consolidated results of operations, financial condition or cash flows. These matters are subject to inherent uncertainties and management's view of these matters may change in the future.

It is not the Company’s business practice to enter into off-balance sheet arrangements. In the normal course of business, the Company may enter into contracts in which it makes representations and warranties that relate to the performance of the Company’s services and products. The Company does not expect any material losses related to such representations and warranties.

Note 17. Interim Financial Data by Segment

Based upon similar economic and operational characteristics, the Company’s strategic business units have been aggregated into the following two reportable segments: Employer Services and PEO Services. The primary components of the “Other” segment are certain corporate overhead charges and expenses that have not been allocated to the reportable segments, including corporate functions, costs related to transformation, severance costs, non-recurring gains and losses, the elimination of intercompany transactions, interest expense and corporate interest income. Certain revenues and expenses are charged to the reportable segments at a standard rate for management reasons. Other costs are recorded based on management responsibility.

EXECUTIVE OVERVIEW

We are a leading global provider of cloud-based Human Capital Management (“HCM”) technology solutions to employers around the world. Our HCM solutions, which include both software and outsourcing services, are designed to help our clients manage their workforce through a dynamic business and regulatory landscape and the changing world of work. We continuously seek to enhance our leading HCM solutions to further support our clients. We see tremendous opportunity ahead as we focus on our three key Strategic Priorities: Leading with Best-in-Class HCM technology, Providing Unmatched Expertise and Outsourcing Solutions, and Leveraging our Global Scale for the Benefit of our Clients. Executing on our Strategic Priorities will be critical to enabling our growth in the years ahead.

During the second quarter, we continued to make meaningful progress on our Strategic Priorities. We announced a partnership that brings together Fiserv’s preeminent small business solutions, specifically Clover® and CashFlow Central℠, with RUN, our industry-leading small business payroll and HR solution. Additionally, we started to integrate the WorkForce Software acquisition, which closed in October, into our global HCM ecosystem. Lastly, since the first quarter introduction of ADP Lyric HCM, our flexible, intelligent, and human-centric Global HCM platform, we have experienced a meaningful increase in ADP Lyric's new business activity. During the second quarter, we also achieved a major milestone by increasing our dividend for the 50th consecutive year.

Highlights from the six months ended December 31, 2024 include:

Revenue growth of 8% to $9,881.1 million; 7% organic constant currency
Earnings before income taxes margin expansion of 90 bps, and adjusted EBIT margin expansion of 90 bps
Diluted and adjusted diluted earnings per share ("EPS") growth of 12%, to $4.69, respectively
Cash returned via shareholder friendly actions of $1,790M, including $1,145M of dividends and $645M of share repurchases
Closed the WorkForce Software acquisition in October and started the integration efforts

For the six months ended December 31, 2024, we delivered solid revenue growth of 8%, 7% organic constant currency. Our pays per control metric, which represents the number of employees on ADP clients' payrolls in the United States when measured on a same-store-sales basis for a subset of clients ranging from small to large businesses, grew 2% for the six months ended December 31, 2024 as compared to the six months ended December 31, 2023. PEO average worksite employees increased 3% for the six months ended December 31, 2024, as compared to the six months ended December 31, 2023.

We have a strong business model, generating significant cash flows with low capital intensity, and offer a suite of products that provide critical support to our clients’ HCM functions. We generate sufficient free cash flow to satisfy our cash dividend and our modest debt obligations, which enables us to absorb the impact of downturns and remain steadfast in our re-investments, longer term strategy, and commitments to shareholder friendly actions. We are committed to building upon our past successes by investing in our business through enhancements in research and development and by driving meaningful transformation in the way we operate. Our financial condition remains solid at December 31, 2024 and we remain well positioned to support our clients and our associates.

For the three months ended December 31, 2024, operating expenses increased due to an increase of $84.5 million of PEO Services zero-margin benefits pass-through costs from $970.7 million to $1,055.2 million. Additionally, for the three months ended December 31, 2024 operating expenses increased by $36.1 million due to higher service and implementation costs in support of our growing revenue.

For the six months ended December 31, 2024, operating expenses increased due to an increase of $156.9 million of PEO Services zero-margin benefits pass-through costs from $1,947.5 million to $2,104.4 million. Additionally, for the six months ended December 31, 2024 operating expenses increased by $60.7 million due to higher service and implementation costs in support of our growing revenue.

Research and development expenses increased for the three and six months ended December 31, 2024 due to increased investments and costs to develop, support, and maintain our new and existing products and the impact from the WorkForce Software acquisition, partially offset by efficiencies from workforce optimization efforts initiated in the prior year and an increase in the capitalizable spend related to the integration of GenAI into our products, as compared to the prior year.

Depreciation and amortization expenses increased for the three and six months ended December 31, 2024 due to the impact from the WorkForce Software acquisition and amortization of new investments in internally developed software primarily for our next-gen products and purchased software, partially offset by lower amortization of customer contracts and lists.

Selling, general and administrative expenses increased for the three and six months ended December 31, 2024 primarily due to increases in selling and marketing expenses of $39.0 million and $73.5 million, respectively, as a result of investments in our sales organization, and an increase from acquisition related costs.

Interest expense increased for the three months ended December 31, 2024 primarily due to a higher volume of average commercial paper borrowings of $4.5 billion and reverse repurchase borrowings of $3.7 billion, as compared to $3.9 billion and $2.4 billion, respectively, for the three months ended December 31, 2023, partially offset by a decrease in average interest rates of 60 basis points for commercial paper and reverse repurchase borrowings.

Interest expense increased for the six months ended December 31, 2024 primarily due to a higher volume of average commercial paper borrowings of $4.7 billion and reverse repurchase borrowings of $3.7 billion, as compared to $4.0 billion and $1.9 billion, respectively, for the six months ended December 31, 2023, partially offset by a decrease in average interest rates of 30 basis points for commercial paper and reverse repurchase borrowings.

Earnings before income taxes increased for the three and six months ended December 31, 2024, due to the components discussed above.

EBIT Margin increased for the three and six months ended December 31, 2024, due to contributions from client funds interest revenues discussed above, increased interest income on corporate funds, and operating efficiencies for costs of servicing our clients on growing revenue, partially offset by increased interest expense and acquisition related expenses.

Adjusted EBIT and Adjusted EBIT margin exclude interest income and interest expense that are not related to our client funds extended investment strategy, legal settlements, and net charges related to our broad-based transformation initiatives, in the applicable periods.

Provision for Income Taxes

The effective tax rate for the three months ended December 31, 2024 and 2023 was 23.6% and 23.2%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities in the three months ended December 31, 2023, partially offset by a higher excess tax benefit on stock-based compensation in the three months ended December 31, 2024.

The effective tax rate for the six months ended December 31, 2024 and 2023 was 23.1% and 22.3%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities, lower reserves for uncertain tax positions and a valuation allowance release in the six months ended December 31, 2023.

Adjusted Provision for Income Taxes

The adjusted effective tax rate for the three months ended December 31, 2024 and 2023 was 23.6% and 23.2%, respectively. The drivers of the adjusted effective tax rate are the same as the drivers of the effective tax rate discussed above.

The adjusted effective tax rate for the six months ended December 31, 2024 and 2023 was 23.1% and 22.3%, respectively. The drivers of the adjusted effective tax rate are the same as the drivers of the effective tax rate discussed above.

For the three months ended December 31, 2024, in addition to the increase in net earnings, diluted EPS increased as a result of the impact of fewer shares outstanding resulting from the repurchase of approximately 0.9 million shares during the three months ended December 31, 2024, and 1.1 million shares during the three months ended December 31, 2023, partially offset by the issuances of shares under our employee benefit plans.

ADP Indemnity provides workers’ compensation and employer’s liability deductible reimbursement insurance protection for PEO Services’ worksite employees up to $1 million per occurrence. PEO Services has secured a workers’ compensation and employer’s liability insurance policy that caps the exposure for each claim at $1 million per occurrence and has also secured aggregate stop loss insurance that caps aggregate losses at a certain level in fiscal years 2012 and prior from an admitted and licensed insurance company of AIG. We utilize historical loss experience and actuarial judgment to determine the estimated claim liability, and changes in estimated ultimate incurred losses are included in the PEO segment. 

Additionally, starting in fiscal year 2013, ADP Indemnity paid premiums to enter into reinsurance arrangements with ACE American Insurance Company, a wholly-owned subsidiary of Chubb Limited (“Chubb”), to cover substantially all losses incurred by the Company up to the $1 million per occurrence related to the workers' compensation and employer's liability deductible reimbursement insurance protection for PEO Services' worksite employees. Each of these reinsurance arrangements limits our overall exposure incurred up to a certain limit. The Company believes the likelihood of ultimate losses exceeding this limit is remote. ADP Indemnity recorded a pre-tax (loss)/benefit of approximately $(0.8) million and $4.1 million for the three and six months ended December 31, 2024, respectively, as compared to approximately $(1.7) million and $4.5 million for the three and six months ended December 31, 2023, respectively. The pre-tax loss for the three months ended December 31, 2024 was primarily a result of more favorable actuarial loss development in workers’ compensation reserves as compared to December 31, 2023. The pre-tax benefit for the six months ended December 31, 2024 was primarily a result of less favorable actuarial loss development in workers’ compensation reserves as compared to December 31, 2023. In July 2024, ADP Indemnity paid a premium of $276 million to enter into a reinsurance arrangement with Chubb to cover substantially all losses incurred by ADP Indemnity for the fiscal 2025 policy year on terms substantially similar to the fiscal 2024 reinsurance policy.

Other

The primary components of “Other” are certain corporate overhead charges and expenses that have not been allocated to the reportable segments, including corporate functions, costs related to our transformation office, severance costs, non-recurring gains and losses, the elimination of intercompany transactions, and other interest income and expense.

Non-GAAP Financial Measures

In addition to our U.S. 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 MeasureU.S. GAAP Measures
Adjusted EBITNet 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 currencyRevenues

We believe that the exclusion of the identified items 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.

(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 reserve reversal of a legal matter from fiscal 2023 previously recorded as an adjustment to EBIT.

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

(d) 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 result using foreign exchange rates consistent with the prior year. The PEO segment is not impacted by acquisitions, dispositions or foreign currency.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

At December 31, 2024, cash and cash equivalents were $2.2 billion, which were primarily invested in time deposits and money market funds.

For corporate liquidity, we expect existing cash, cash equivalents, marketable securities, cash flow from operations together with our $10.3 billion of committed credit facilities and our ability to access both long-term and short-term debt financing from the capital markets will be adequate to meet our operating, investing, and financing activities such as regular quarterly dividends, share repurchases, acquisitions and capital expenditures for the foreseeable future. Our financial condition remains solid at December 31, 2024 and we have sufficient liquidity.

For client funds liquidity, we have the ability to borrow through our financing arrangements under our U.S. short-term commercial paper program and our U.S., Canadian and United Kingdom short-term reverse repurchase agreements ($7.3 billion of which is available on a committed basis in the U.S.), together with our $10.3 billion of committed credit facilities and our ability to use corporate liquidity when necessary to meet short-term funding requirements related to client funds obligations. Please see “Quantitative and Qualitative Disclosures about Market Risk” for a further discussion of the risks related to our client funds extended investment strategy. See Note 10 of our Consolidated Financial Statements for a description of our short-term financing including commercial paper.

Operating, Investing and Financing Cash Flows

Our cash flows from operating, investing, and financing activities, as reflected in the Statements of Consolidated Cash Flows for the six months ended December 31, 2024 and 2023, respectively, are summarized as follows:
Six Months Ended
December 31,
20242023$ Change
Cash provided by / (used in):
Operating activities$1,974.7 $1,358.9 $615.8

Net change in cash, cash equivalents, restricted cash, and restricted cash equivalents$6,518.2 $5,107.8 $1,410.4 

Net cash flows provided by operating activities increased due to favorable changes in the components of working capital and an increase in growth in our business, as compared to the six months ended December 31, 2023.

Net cash flows used in investing activities changed due to the acquisition of Workforce Software with a cash disbursement of $1,160.6 million and the timing of purchases and proceeds of corporate and client funds marketable securities of $1,664.3 million.

Net cash flows used in financing activities changed due to a net increase in the cash flow from client funds obligations of $3,668.5 million, which is due to the timing of impounds from our clients and payments to our clients' employees and other payees, along with proceeds from the issuance of debt, offset by a net decrease in cash distributed from the Internal Revenue Service as of December 31, 2024, which was refunded to our clients, repurchases of common stock, dividends paid, and proceeds related to reverse repurchase agreements.

From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase program. The Company considers several factors in determining when to execute share repurchases, including, among other things, actual and potential acquisition activity, cash balances and cash flows, issuances due to employee benefit plan activity, and market conditions. We purchased approximately 2.4 million shares of our common stock at an average price per share of $274.42 during the six months ended December 31, 2024, as compared to purchases of 2.1 million shares at an average price per share of $238.29 during the six months ended December 31, 2023.

Capital Resources and Client Funds Obligations

We have $4.0 billion of senior unsecured notes with maturity dates in 2025, 2028, 2030 and 2034. We may from time to time revisit the long-term debt market to refinance existing debt, finance investments including acquisitions for our growth, and maintain the appropriate capital structure. However, there can be no assurance that volatility in the global capital and credit markets would not impair our ability to access these markets on terms acceptable to us, or at all. See Note 11 of our Consolidated Financial Statements for a description of our long-term financing.

Our U.S. short-term funding requirements primarily related to client funds are sometimes obtained on an unsecured basis through the issuance of commercial paper, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. This commercial paper program provides for the issuance of up to $10.3 billion in aggregate maturity value. Our commercial paper program is rated A-1+ by Standard & Poor’s, Prime-1 (“P-1”) by Moody’s and F1+ by Fitch. These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At December 31, 2024 and June 30, 2024, the Company had no commercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

Our U.S., Canadian, and United Kingdom short-term funding requirements related to client funds obligations are sometimes obtained on a secured basis through the use of reverse repurchase agreements, which are collateralized principally by government and government agency securities, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. These agreements generally have terms ranging from overnight to up to five business days. We have successfully borrowed through the use of reverse repurchase agreements on an as-needed basis to meet short-term funding requirements related to client funds obligations. We have $7.3 billion available to us on a committed basis under the U.S. reverse repurchase agreements. At December 31, 2024, the Company had no outstanding obligations related to reverse repurchase agreements. At June 30, 2024, the Company had $385.4 million of outstanding obligations related to reverse repurchase agreements which were fully paid in early July 2024. Details of the reverse repurchase agreements are as follows:

Average outstanding balances (in billions)$3.7 $2.4 $3.7 $1.9 
Weighted average interest rates4.8 %5.4 %5.0 %5.4 %

We vary the maturities of our committed credit facilities to limit the refinancing risk of any one facility. We have a $4.55 billion, 364-day credit agreement that matures in June 2025 with a one year term-out option. In addition, we have a five-year $2.25 billion credit facility and a five-year $3.5 billion credit facility maturing in June 2028 and June 2029, respectively, each with an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. The primary uses of the credit facilities are to provide liquidity to the commercial paper program and funding for general corporate purposes, if necessary. We had no borrowings through December 31, 2024 under the credit facilities. We believe that we currently meet all conditions set forth in the revolving credit agreements to borrow thereunder and we are not aware of any conditions that would prevent us from borrowing part or all of the $10.3 billion available to us under the revolving credit agreements. See Note 10 of our Consolidated Financial Statements for a description of our short-term financing, including credit facilities.

Our investment portfolio does not contain any asset-backed securities with underlying collateral of sub-prime mortgages, alternative-A mortgages, sub-prime auto loans or sub-prime home equity loans, collateralized debt obligations, collateralized loan obligations, credit default swaps, derivatives, auction rate securities, structured investment vehicles or non-investment grade fixed-income securities. We own AAA-rated senior tranches of primarily fixed rate auto loan, credit card, and equipment lease receivables, secured predominantly by prime collateral. All collateral on asset-backed securities has performed as expected through December 31, 2024. In addition, we own U.S. government securities which primarily include debt directly issued by Federal Farm Credit Banks and Federal Home Loan Banks. Our client funds investment strategy is structured to allow us to average our way through an interest rate cycle by laddering the maturities of our investments out to five years (in the case of the extended portfolio) and out to ten years (in the case of the long portfolio). This investment strategy is supported by our short-term financing arrangements necessary to satisfy short-term funding requirements relating to client funds obligations. See Note 7 of our Consolidated Financial Statements for a description of our corporate investments and funds held for clients.

Capital expenditures for the six months ended December 31, 2024 were $98.2 million, as compared to $94.0 million for the six months ended December 31, 2023. We expect capital expenditures in fiscal 2025 to be between $180 million and $200 million, as compared to $211.7 million in fiscal 2024.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our overall investment portfolio is comprised of corporate investments (cash and cash equivalents, marketable securities) and client funds assets (funds that have been collected from clients but have not yet been remitted to the applicable tax authorities or client employees).

Our corporate investments are invested in cash and cash equivalents and highly liquid, investment-grade marketable securities. These assets are available for our regular quarterly dividends, share repurchases, capital expenditures and/or acquisitions, as well as other corporate operating purposes. All of our short-term and long-term fixed-income securities are classified as available-for-sale securities.

Our client funds assets are invested with safety of principal, liquidity, and diversification as the primary objectives. Consistent with those objectives, we also seek to maximize interest income and to minimize the volatility of interest income. Client funds assets are invested in highly liquid, investment-grade marketable securities, with a maximum maturity of 10 years at the time of purchase, and money market securities and other cash equivalents.  
    
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. Our client funds investment strategy is structured to allow us to average our way through an interest rate cycle by laddering the maturities of our investments out to five years (in the case of the extended portfolio) and out to ten years (in the case of the long portfolio). As part of our client funds investment strategy, we use the 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. In circumstances where we experience a reduction in employment levels due to a slowdown in the economy, we may make tactical decisions to sell certain securities or not reinvest maturing securities in order to reduce the size of the funds held for clients to correspond to client funds obligations. We minimize the risk of not having funds collected from a client available at the time such client’s obligation becomes due by impounding, in virtually all instances, the client’s funds in advance of the timing of payment of such client’s obligation. As a result of this practice, we have consistently maintained the required level of client funds assets to satisfy all of our obligations.

There are inherent risks and uncertainties involving our investment strategy relating to our client funds assets. Such risks include liquidity risk, including the risk associated with our ability to liquidate, if necessary, our available-for-sale securities in a timely manner in order to satisfy our client funds obligations. However, our investments are made with the safety of principal, liquidity, and diversification as the primary goals to minimize the risk of not having sufficient funds to satisfy all of our client funds obligations. We also believe we have significantly reduced the risk of not having sufficient funds to satisfy our client funds obligations by consistently maintaining access to other sources of liquidity, including our corporate cash balances, available borrowings under our $10.3 billion commercial paper program (rated A-1+ by Standard and Poor’s, P-1 by Moody’s, and F1+ by Fitch, the highest possible short-term credit ratings), and our ability to engage in reverse repurchase agreement transactions ($7.3 billion of which is available on a committed basis in the U.S.) and available borrowings under our $10.3 billion committed credit facilities. The reduced availability of financing during periods of economic turmoil, even to borrowers with the highest credit ratings, may limit our ability to access short-term debt markets to meet the liquidity needs of our business. In addition to liquidity risk, our investments are subject to interest rate risk and credit risk, as discussed below.

We have established credit quality, maturity, and exposure limits for our investments. The minimum allowed credit rating at time of purchase for Corporate, Canadian government agency and Canadian provincial bonds is BBB, for asset-backed securities is AAA, and for municipal bonds is A. The maximum maturity at time of purchase for BBB-rated securities is 5 years, and for single A rated securities, AA-rated and AAA-rated securities is 10 years. Time deposits and commercial paper must be rated A-1 and/or P-1. Money market funds must be rated AAA/Aaa-mf.

Total available-for-sale securities at fair value$33,019.9 $31,207.5 
 
We are exposed to interest rate risk in relation to securities that mature, as the proceeds from maturing securities are reinvested. Factors that influence the earnings impact of interest rate changes include, among others, the amount of invested funds and the overall portfolio mix between short-term and long-term investments. This mix varies during the fiscal year and is impacted by daily interest rate changes. The annualized interest rate earned on our entire portfolio increased from 2.7% for the six months ended December 31, 2023 to 3.2% for the six months ended December 31, 2024. A hypothetical change in both short-term interest rates (e.g., overnight interest rates or the federal funds rate) and intermediate-term interest rates of 25 basis points applied to the estimated average investment balances and any related short-term borrowings would result in approximately a $20 million impact to earnings before income taxes over the ensuing twelve-month period ending December 31, 2025. A hypothetical change in only short-term interest rates of 25 basis points applied to the estimated average short-term investment balances and any related short-term borrowings would result in approximately a $9 million impact to earnings before income taxes over the ensuing twelve-month period ending December 31, 2025.

We are exposed to credit risk in connection with our available-for-sale securities through the possible inability of the borrowers to meet the terms of the securities. We limit credit risk by investing in investment-grade securities, primarily AAA-rated and AA- rated securities, as rated by Moody’s, Standard & Poor’s, DBRS for Canadian dollar denominated securities, and Fitch for asset-backed and commercial-mortgage-backed securities. In addition, we limit amounts that can be invested in any security other than U.S. government and government agency, Canadian government, and United Kingdom government securities.

We operate and transact business in various foreign jurisdictions and are therefore exposed to market risk from changes in foreign currency exchange rates that could impact our consolidated results of operations, financial position, or cash flows. We manage our exposure to these market risks through our regular operating and financing activities and, when deemed appropriate, through the use of derivative financial instruments. We may use derivative financial instruments as risk management tools and not for trading purposes.

CRITICAL ACCOUNTING POLICIES

Our Consolidated Financial Statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates, judgments, and assumptions that affect reported amounts of assets, liabilities, revenues, expenses, and other comprehensive income. We continually evaluate the accounting policies and estimates used to prepare the Consolidated Financial Statements. The estimates are based on historical experience and assumptions believed to be reasonable under current facts and circumstances. Actual amounts and results could differ from these estimates made by management. Refer to Note 2 of our Consolidated Financial Statements for changes to our accounting policies effective for the fiscal 2025.

NEW ACCOUNTING PRONOUNCEMENTS

See Note 2, New Accounting Pronouncements, of Notes to the Consolidated Financial Statements for a discussion of recent accounting pronouncements.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

The information called for by this item is provided under the caption “Quantitative and Qualitative Disclosures about Market Risk” under Item 2 – Management's Discussion and Analysis of Financial Condition and Results of Operations.

Item 4.  Controls and Procedures

The Company carried out an 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) of the Securities Exchange Act of 1934 (the “evaluation”).  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 Securities Exchange Act of 1934 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 December 31, 2024 in ensuring that (i) information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 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.

There was no change in the Company's internal control over financial reporting that occurred during the three months ended December 31, 2024 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II.  OTHER INFORMATION

Except as noted below, all other items are either inapplicable or would result in negative responses and, therefore, have been omitted.

Item 1.  Legal Proceedings

In the normal course of business, the Company is subject to various claims and litigation.  While the outcome of any litigation is inherently unpredictable, the Company believes it has valid defenses with respect to the legal matters pending against it and the Company believes that the ultimate resolution of these matters will not have a material adverse impact on its financial condition, results of operations, or cash flows.

With respect to the disclosure of administrative or judicial proceedings arising under any Federal, State, or local provisions regulating the discharge of materials into the environment or that are primarily for the purpose of protecting the environment, the Company has determined that the following threshold is reasonably designed to result in disclosure of any such proceeding that is material to its business or financial condition: any proceeding when the potential monetary sanctions exceed $1 million.

SEPARATION AGREEMENT AND RELEASE

This Separation Agreement and General Release (hereinafter, the “Agreement”) is made and entered into this 27th day of January, 2025 by and between John C. Ayala (hereinafter referred to as “Executive”), and Automatic Data Processing, Inc. (hereinafter referred to as the “Company”).
In exchange for the mutual promises contained herein and pursuant to the Automatic Data Processing, Inc. Corporate Officer Severance Plan (the “Corporate Officer Severance Plan”), Executive and the Company, intending to be bound hereby, covenant and agree as follows:
1.Executive is a participant in the Corporate Officer Severance Plan. The parties agree that for the purposes of facilitating an amicable separation of Executive from the Company, Company is treating Executive’s termination as a “Qualifying Termination” under the Corporate Officer Severance Plan, which treatment would entitle Executive to the benefits and obligations as set forth therein. Executive’s employment with the Company will terminate at the close of business on March 31, 2025 (the “Separation Date”). As of April 1, 2025, Executive will cease to be an officer of the Company.
2.The Company and Executive further agree to the following:
(a)The Company will pay Executive a separation payment in the total gross amount of $1,147,200.00. Except as set forth in this paragraph 2(a), this separation payment will be paid out in pro-rata installments in accordance with the Company’s payroll practices (which equals the gross monthly amount of $63,733.33 for each month (such aggregate monthly amount is the “Monthly Installments”)) between the Separation Date and the 18-month anniversary of the Separation Date. The Monthly Installments will be made on the Company’s regular pay dates. Notwithstanding the foregoing, no installment will be paid until Executive has executed and delivered to the Company a Restrictive Covenant Agreement and a Release (and the time to



revoke has passed) as set forth in paragraphs 3(b) and 7(a) below. However, the first installment will be in an amount that covers the period of time from the Separation Date through the date of such first payment.
(b)Executive will be entitled to be paid a prorated bonus (based upon a target bonus of $1,147,200.00) in respect of FY’25, based on actual performance for the full fiscal year as set forth in Section 1.17 of the Corporate Officer Severance Plan; such bonus will be paid to Executive in accordance with the Company’s customary cycle.
(c)With respect to the Company’s performance stock unit program, the Executive will be entitled to receive: (i) the share units and dividend equivalents earned in respect of the original September 2022 target award (which target award includes dividend equivalents to date and will be adjusted for future quarterly dividend equivalents), subject to the achievement of the Company’s performance goals applicable to such award, with any such award to be paid within 20 business days of September 1, 2025, (ii) the share units and dividend equivalents earned in respect of the original September 2023 target award (which target award includes dividend equivalents to date and will be adjusted for future quarterly dividend equivalents), subject to the achievement of the Company’s performance goals applicable to such award, with any such award to be paid within 20 business days of September 1, 2026; and (iii) the share units and dividend equivalents earned in respect of the original September 2024 target award (which target award includes dividend equivalents to date and will be adjusted for future quarterly dividend equivalents), subject to the achievement of the Company’s performance goals applicable to such award, with any such award to be paid within 20 business days of September 1, 2027. All other terms of the PSU program will remain in full force and effect.
(d)     All outstanding unvested ADP stock options previously granted to Executive will continue to vest in accordance with their terms for a period of 36 months after September 30, 2026, and Executive may exercise all such options within 37 months of September 30, 2026.



Notwithstanding the foregoing, all vested stock options must be exercised prior to their original expiration date, regardless of the exercise periods set forth herein. All vested stock options that are not exercised within the time periods set forth above will be automatically exercised by Fidelity Investments. Shares will be withheld to cover the option cost and any applicable taxes and net shares will be deposited into your account with Fidelity.
(e)     All outstanding unvested units of ADP common stock with time-based restrictions previously granted to Executive under the Company’s time-based restricted stock unit program will continue to vest in accordance with their terms. All other terms and conditions of the time-based restricted stock unit program will remain in effect.
(f)     Executive understands and acknowledges that the terms and conditions of the calendar year 2025 10b5-1 Trading Plan (entered into September 2024) executed with Fidelity Investments will remain in full force and effect for calendar year 2025 subject to earlier termination in accordance with the Terms and Conditions of such 10b5-1 Trading Plan. Subject to these 10b5-1 trading plans, Executive understands and acknowledges that for a period of six (6) months following the Separation Date he will continue to be a “Restricted Person” as such term is used in the Company’s Insider Trading Policy, and he will continue to abide by all rules and limitations applicable thereunder to Restricted Persons.
(g)     The Company will timely pay Executive all of the “Accrued Obligations” (as defined in the Corporate Officer Severance Plan) including without limitation Executive’s accrued base salary and unused vacation (which for avoidance of doubt includes all then accrued vacation) as of the Separation Date.
(h)     The Company will reimburse Executive for outstanding expenses properly incurred through the Separation Date that are submitted to the Company no later than the thirty (30) days following the Separation Date. All such expenses will be reimbursed in accordance with the Company’s existing policy.



(i)     The Company will allow Executive to keep the car leased to him by the Company under the Company’s Executive Fleet Program through the 18-month anniversary of the Separation Date; upon such 18-month anniversary, Executive will either return such car to Company or purchase such car in accordance with the terms of the Executive Fleet Program. ADP’s Director of Global Fleet Management will coordinate the details of such transfer with Executive.
(j)     Executive’s welfare benefits (medical, dental, vision, wellness, life, long-term disability, Flexible Spending Accounts (“FSA”), Accidental Death & Dismemberment Insurance, Business Travel Accident Insurance, Personal Accident Insurance and any other welfare benefits the Company may provide) will terminate effective as of the close of the Separation Date. This paragraph (j) will not be deemed to affect the conversion rights under any life insurance plans. To the extent he participates in such plans as of the Separation Date, Executive will have the right to continue medical, dental, prescription drug, vision and FSA benefits as permitted by law under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) and will not incur a break in service if he elects COBRA. Executive and any eligible dependents will also be eligible to enroll in the ADP Executive Retiree Health Care Plan (the “Retiree Health Care Plan”) as of April 1, 2025, in accordance with the terms of the Retiree Health Care Plan. Executive will be separately notified of conversion privileges, if any, for Executive’s other health and welfare benefits. Unless otherwise specifically stated herein, nothing in the Agreement constitutes a waiver of any claim for health or long term disability benefits that accrue prior to the Separation Date. Such claims will be processed according to the terms and conditions of the controlling plan documents. Those plans have not been modified in any way by the Agreement.
(k)     For purposes of the Automatic Data Processing, Inc. Retirement and Savings Plan and/or the Automatic Data Processing, Inc. Pension Retirement Plan (collectively referred to as the “Plans”), Executive will be considered a terminated employee as of the close of the



Separation Date. As such, contributions, vesting, matches and other service-based benefits, rights and features accorded to employees will terminate as of the close of the Separation Date. All the terms and conditions of the Plans will be governed by the controlling plan documents. The Plans have not been modified in any way by the Agreement.
(l)     Executive agrees to abide by all of the terms and conditions of agreements with the Company executed in connection with all ADP stock options, restricted stock units or PSU awards previously granted to Executive (the “Stock Agreements”), and that any non-competition period, as defined in any such Stock Agreements, will not terminate until 12 months after the last Monthly Installment payment under paragraph 2(a) hereunder. Any use of the term “Restrictive Covenant” in the Agreement will mean any non-competition, non-solicitation, non-disparagement, non-disclosure or confidentiality obligations reflected in the provisions of the Agreement or any other agreement with the Company that Executive has entered into, or any Company plan, policy or arrangement that applies to Executive. If Executive violates any Restrictive Covenant prior to either the payment of any amounts under the Agreement or the vesting of any rights or lapsing of any restrictions on any ADP equity as described hereunder (and as further set forth in paragraphs 2(m) and 2(n) hereunder specifically regarding the Executive Retirement Plan and the Supplemental Officer Retirement Plan, respectively), then, in addition to the exercise of any other rights the Company may have as a consequence of such breach, Executive will have immediately forfeited the receipt of any cash payments otherwise owing hereunder as well as the benefit of the vesting of any rights or lapsing of any restrictions on any ADP equity Executive would otherwise expect to receive hereunder.
(m)     Executive is a “Participant” as defined in the Automatic Data Processing, Inc. Executive Retirement Plan (“ERP”). Executive’s benefits under the ERP will be determined in accordance with, and under the terms of, the ERP. Among other things, the ERP provides that if a participant violates the non-competition provisions of any agreement he has entered into with



the Company within 24 months after the Separation Date, such Participant will forever and irrevocably forfeit all benefits otherwise due him under the terms of the ERP. The ERP will not have been deemed modified in any way by the Agreement. For purposes of the 24-month period of measurement under the ERP, Executive will be considered to have terminated employment with the Company as of the Separation Date.
(n)     Executive is a “Participant” as defined in the Automatic Data Processing, Inc. Amended and Restated Supplemental Officer Retirement Plan (the “SORP”). Executive’s benefits under the SORP shall be determined in accordance with, and under the terms of, the SORP. Among other things, the SORP provides that if a participant violates the non-competition provisions of any agreement he has entered into with the Company within 24 months after the Separation Date, such Participant shall forever and irrevocably forfeit all benefits otherwise due him under the terms of the SORP. The SORP will not have been deemed modified in any way by this Agreement. For purposes of the 24-month period of measurement under the SORP, Executive shall be considered to have terminated employment with the Company as of the Separation Date.
(o)     Executive’s heirs, representatives, assigns or estate will be entitled to any payments pursuant to paragraph 2 of the Agreement in the event of Executive’s death in accordance with Section 8.1 of the Corporate Officer Severance Plan.
(p)     The Company will withhold from any payment made under the Agreement any applicable federal, state and local taxes and social security taxes, as well as any other standard deductions.
3.Executive and the Company (which, for purposes of this paragraph 3, will include any of the Company’s affiliates), agree to the following with the proviso exceptions herein also applying to any similar restrictive covenant:



(a)Executive agrees to notify the Company of his intent to accept any offer of employment commencing prior to the first anniversary of the last Monthly Installment payment under paragraph 2(a) hereunder for the purpose of confirming that commencing such employment will not otherwise violate a Restrictive Covenant. Specifically, Executive agrees to inform the Company of (i) the entity making such offer (including the name of the ultimate corporate parent entity, if the entity making the offer is a subsidiary or division with a different name from the ultimate parent company), and (ii) the scope of duties and title of the position to be filled, both by telephone (973-974-5000) and in writing to Paul Boland, Chief Human Resources Officer, One ADP Boulevard, M/S 427, Roseland, NJ 07068, with a copy of such written communication to David Kwon, Chief Legal Officer, One ADP Boulevard, M/S 450, Roseland, NJ 07068, and by email to paul.boland@adp.com, with a copy to david.kwon@adp.com. Mr. Boland or his designee will undertake to respond to Executive’s notice within five business days of receipt of Executive’s written notice.
(b)Executive will execute and deliver to the Company a Restrictive Covenant Agreement in the form attached hereto as Exhibit A (the “Restrictive Covenant Agreement”) within 45 days of the Separation Date as required by Section 3 of the Corporate Officer Severance Plan. Should Executive fail to timely execute and deliver to the Company the Restrictive Covenant Agreement, Executive agrees that he will not be entitled to the benefits provided under the Agreement or the Corporate Officer Severance Plan, and this Agreement will become null and void.
(c)In addition to any further “Litigation Cooperation” requirements set forth in Section 4 of the Corporate Officer Severance Plan, Executive agrees to reasonably cooperate with the Company, and to provide all information and sign any corporate records and instruments that the Company may hereafter reasonably request with respect to any matter involving his present or former relationship with the Company (including any direct or indirectly held



subsidiaries), the work he has performed, or any present or former employees or clients of the Company.
(d)In addition to any further “Litigation Cooperation” requirements set forth in Section 4 of the Corporate Officer Severance Plan, Executive agrees that if he is served with a subpoena or court order to testify with respect to any matter involving his present or former relationship with the Company, the work he has performed, or present or former employees or clients of the Company, he will, within 5 days of receipt of such subpoena or court order, notify the “Company”, c/o Automatic Data Processing, Inc., One ADP Boulevard, Roseland, New Jersey 07068, Attention: Chief Legal Officer, unless the Executive receives written advice from his legal counsel advising that he is not legally permitted to provide such notice to the Company. If Executive does not provide such notice based upon written advice from his legal counsel that he is not legally permitted to provide such notice to the Company, Executive agrees that he will request that the person, entity, court or agency serving such subpoena or court order provide notice consistent with this paragraph 3(d).
4.Executive agrees that any waiver on the part of the Company as to compliance with any of the terms and conditions of the Agreement will not operate as a waiver of, or estoppel with respect to, any prior, subsequent or other failure by Executive to perform his obligations under the Agreement.
5.Executive acknowledges that this Agreement, along with the other agreements referenced herein whose terms survive the Separation Date, is the entire agreement between the parties concerning the subject matter hereof. Each party acknowledges that there are no representations by the other party, oral or written, not set forth in the Agreement upon which such party relied in signing the Agreement.
6.Section 409A:



(a)The intent of the parties is that payments and benefits under this Agreement comply with or will be exempt from Internal Revenue Code Section 409A and the regulations and guidance promulgated thereunder (collectively “Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement will be interpreted to be exempt from Section 409A or in compliance therewith, as applicable.
(b)A termination of employment will not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits that are considered nonqualified deferred compensation under Section 409A upon or following a termination of employment, unless such termination is also a “separation from service” within the meaning of Section 409A and the payment thereof prior to a “separation from service” would violate Section 409A. For purposes of any such provision of this Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms will mean “separation from service.”
(c)The parties agree and acknowledge that on Executive’s Separation Date, Executive will be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) and any payment or the provision of any benefit that is considered nonqualified deferred compensation under Section 409A payable on account of a “separation from service” which would otherwise be made or provided during the six (6) month period following Executive’s separation from service will instead be made or provided, in lump sum, on the first business day following the date which is the earlier of (A) the expiration of the six (6) month period measured from the date of Executive’s “separation from service,” and (B) the date of Executive’s death. Any remaining payments and benefits due under this Agreement will be paid or provided in accordance with the normal payment dates specified for them herein.
(d)With respect to the payment or provision of any benefit constituting nonqualified deferred compensation subject to Section 409A (i) all expenses or other reimbursements as



provided herein will be payable in accordance with the Company’s policies in effect from time to time, but in any event will be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by Executive, (ii) no such reimbursement or expenses eligible for reimbursement in any taxable year will in any way affect the expenses eligible for reimbursement in any other taxable year, and (iii) the right to reimbursement or in-kind benefits will not be subject to liquidation or exchanged for another benefit.
(e)For purposes of Section 409A, Executive’s right to receive any installment payments pursuant to this Agreement will be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment will be made within thirty (30) days following the date of termination”), the actual date of payment within the specified period will be within the sole discretion of the Company.
(f)Nothing contained in this Agreement will constitute any representation or warranty by the Company regarding compliance with Section 409A and none of the Company, its direct or indirect parents, subsidiaries or affiliates or any of their stockholders, employees or representatives will have any liability to Executive with respect thereto.

7.     Release:
(a)     The Executive will execute and deliver to the Company an irrevocable general release in the form attached hereto as Exhibit B (the “Release”) within 45 days of the Separation Date as required by Section 3 of the Corporate Officer Severance Plan. Should Executive fail to timely execute and deliver to the Company the Release, Executive agrees that he will not be entitled to the benefits provided under this Agreement or the Corporate Officer Severance Plan, and this Agreement will become null and void.



(b)     Except as set forth herein, Executive acknowledges, represents and warrants that the Company owes him no other wages, commissions, bonuses, vacation pay or other compensation or payments of any nature, other than that specifically provided for in the Agreement. Executive further acknowledges that except as provided for herein, the Company will not have any obligation to him or to any other person or entity for any other monies or benefits including, but not limited to, attorneys’ fees, car allowance, use of a Company car, relocation expenses, stock, stock options, restricted stock shares or units, stock purchase plan, pension, medical, life, short-term disability, long-term disability or other insurance, ERISA benefits, severance or any obligation set forth in any agreement of employment or other agreement with the Company, whether such agreement is express or implied.
(c)     Executive warrants that as of the date hereof he is unaware of any conduct by the Company, any of its affiliates, or any of its or their employees, officers, directors, agents, carriers and shareholders and its and their predecessors, successors and assigns that he reasonably believes could form the basis of a material claim against any of them, other than those matters which may have been previously discussed with members of the Company’s legal department in connection with any pending or threatened litigation.
8.     Notification of Rights:
(a)     Executive has twenty-one (21) days from his receipt of the Agreement on December 16, 2024 to consider it, and to return the signed Agreement to David Kwon, Chief Legal Officer, Automatic Data Processing, Inc., One ADP Boulevard, M/S 450, Roseland, New Jersey 07068. In order for Executive to fully understand his statutory rights and the legal effect of a waiver by Executive of those rights, he has the right to consult with an attorney.
(b)     If Executive elects to sign the Agreement it means that: (i) he has read the Agreement and understands it; (ii) he has not received any inducements to sign the Agreement other than what is set forth in the Agreement; (iii) he has had adequate opportunity to consult



with an attorney of his choosing and has been advised to do so if he chooses; and (iv) he has signed the Agreement voluntarily and knowingly.
(c)     Executive understands and agrees that if he chooses to sign the Agreement before the expiration of the twenty-one (21) day consideration period, he has waived the remainder of that period.
(d)     After Executive has signed the Agreement, Executive may revoke his acceptance of it within seven (7) days from the date of his execution of the Agreement. Revocation must be made by submitting a written revocation by hand delivery or certified mail, return receipt requested, to David Kwon, Chief Legal Officer, Automatic Data Processing, Inc., One ADP Boulevard, M/S 450, Roseland, New Jersey 07068. If revocation of the Agreement is not made within the seven (7) day revocation period, the Agreement will become final, binding and irrevocable on both parties (except as set forth herein in paragraphs 3(b) and 7(a)).

Exhibit A

















RESTRICTIVE COVENANT AGREEMENT
I am a participant in the Automatic Data Processing, Inc. Corporate Officer Severance Plan, and my employment as an executive employee with Automatic Data Processing, Inc., or one of its subsidiaries or affiliated companies (collectively, “ADP”) has been terminated. While employed as an executive employee of ADP, I participated in policy decisions and enjoyed substantial compensation and benefits from ADP, including participation in its 2018 Omnibus Award Plan, and have had access to ADP’s Confidential Information, proprietary information, and trade secrets about the Business of ADP, ADP’s operations, systems, techniques, software and processes, its Clients, Business Partners, Vendors, and other unique trade and business methods, all of which are valuable assets of ADP that are developed at great effort and expense to ADP. I also have had significant contact with ADP’s current and prospective Clients, Business Partners, and/or Vendors in order to develop ADP’s goodwill and client relations so that I could promote ADP’s interests and objectives, and I understand that ADP has invested a significant amount of time and financial resources to develop my skills to assist me in performing my job duties for ADP. While these current and prospective Clients, Business Partners, and/or Vendors may be secured or serviced by ADP associates, including me, I acknowledge that such individuals or entities remain at all times those of ADP and that the goodwill engendered by the relationships is intended to inure only to the benefit of ADP; the goodwill is owned by ADP; and ADP shall be the sole beneficiary of such goodwill during and after the termination of my employment with ADP.

I understand that ADP is a profit-generating business operating in a highly competitive business environment and that it has a valid interest in protecting its valuable assets, including its Confidential Information, proprietary information, and trade secrets, its goodwill and business relationships with its Clients, Business Partners, Vendors, and employees, and the specialized training of its employees, and I recognize that my use of ADP’s valuable assets, directly or indirectly, against or in competition with ADP after my employment will result in irreparable harm to ADP. Accordingly, I understand that this Restrictive Covenant Agreement is meant to limit reasonably and fairly my competition following the end of my employment, and to define the corresponding obligations between me and ADP regarding: (1) unfair competition, (2) the solicitation of Clients, Business Partners or Vendors for or on behalf of ADP’s competitors, (3) the solicitation of ADP’s employees, and (4) the treatment of proprietary information, Confidential Information, and trade secrets.

NOW, THEREFORE, in consideration of my participation in the Automatic Data Processing, Inc. Corporate Officer Severance Plan and receipt of substantial compensation and benefits from ADP thereunder, the mutual benefits conferred herein, and for other good and valuable consideration (the receipt and sufficiency of all of which I hereby acknowledge), I agree as follows:

1.Definitions.
a.“Business of ADP” means the following businesses or services: (i) business outsourcing and human capital management solutions, including, without limitation, human resource, payroll, time, attendance and labor management, pre-employment, talent management, compliance and payment solutions, tax and benefits and retirement administration solutions and employment administration outsourcing solutions, which ADP provides globally; (ii) workers



compensation and health insurance, which ADP provides in the United States and Canada through its licensed insurance agencies and consulting services relating to its business outsourcing and human capital management solutions; and (iii) data-driven business intelligence on issues in human capital management, employment, and workforce trends.

b.“Business Partners” means any individual, corporation, limited liability company, partnership, joint venture, association, or other entity, regardless of form, that is or has been in a commercial or business relationship with ADP (excluding Clients and Vendors), including, without limitation, (i) referral partners, resellers, brokers, distributors, licensees, franchisees and marketing partners, (ii) implementation, integration and development partners, (iii) co-investors and joint venture partners, and (iv) any other individual or entity whose products or services ADP purchases, acquires or licenses for use with, or redistribution to, a third party (including Clients).

d.“Competing Business” means any individual (including me), corporation, limited liability company, partnership, joint venture, association, or other entity, regardless of form, that is engaged in any business or enterprise that is the same as, or substantially the same as, that part of the Business of ADP in which I have worked or to which I have been exposed during my employment with ADP (regardless of whether I worked only for a particular segment of that part of the business in which I worked – for example, business segments based on the number of employees a Client has or a particular class of business using an ADP product or service).

e.“Confidential Information” means information and the compilation of information known or possessed by me because of my employment at ADP that is created, compiled, received or gathered by ADP or its agents and is related to the Business of ADP, that is valuable to ADP, and which ADP endeavors to protect from disclosure or use by its competitors and others who could benefit from its use, whether in written, tangible, electronic or any other form of media.

This definition of Confidential Information excludes information that is or becomes known or generally available in the public domain through lawful means other than through my act or failure to act. This definition of Confidential Information and the use of the term Confidential Information in this Restrictive Covenant Agreement are not meant to limit ADP’s rights under applicable trade secrets laws, and ADP specifically reserves all of its rights under all applicable laws concerning trade secrets.

f.     “Creative Works” means any and all works of authorship including, for example, written documents, spreadsheets, graphics, designs, trademarks, service marks, algorithms, computer programs or code, protocols, formulas, mask works, brochures, presentations, photographs, music or compositions, manuals, reports, and compilations of various elements, whether or not patentable or registrable under copyright, trademark, or similar domestic and international laws.

2.     Duties and Best Efforts. I agree that I am prohibited from accessing any of ADP’s computer systems, servers, drives, or databases for any competitive or conflicting purpose and that any authorization for such access is revoked and prohibited by ADP once I engage in any competitive or conflicting activities or take any material steps towards accomplishing any competitive or conflicting activities.

3.     Non-Competition. I agree that during my Severance Period and for a period of twelve (12) months following my Severance Period, I will not, directly or indirectly, own, manage, operate, join, control, finance, be employed by or with, or participate in any manner with a Competing Business where doing so will require me to (i) provide the same or substantially similar services to a Competing Business as those which I provided to ADP while employed, or (ii) use, disclose or disseminate ADP’s Confidential Information or trade secrets. However, nothing shall prevent me from owning, as an inactive investor, securities of any competitor of ADP which is listed on a national securities exchange.

4.     Non-Solicitation of and Non-Interference with Clients, Business Partners, and Vendors.

I also agree that I will not induce or encourage or attempt to induce or encourage any Client to cease doing business with ADP or materially alter their business relationship with ADP.

b.     Business Partners: I agree that during my Severance Period and for a period of twelve (12) months following my Severance Period, I will not, either on my own behalf or for any Competing Business, directly or indirectly engage, contract with, solicit, divert, appropriate or accept any business from, or attempt to engage, contract with, solicit, divert, appropriate or accept any business from any Business Partner for the purpose of providing to me or any Competing Business any product or service that is (a) the same as or substantially similar to the product or service provided to ADP and which ADP uses for, uses for obtaining, or distributes to, its Clients or (b) specialized, customized or designed by the Business Partner for ADP. This provision applies only to a Business Partner: (i) with whom ADP currently has a commercial or business relationship in connection with the Business of ADP; (ii) with whom ADP has had a commercial or business relationship in connection with the Business of ADP within the one (1) year period prior to my voluntary or involuntary termination of employment, for whatever reason, with or without cause, from ADP; or (iii) about whom I have any Confidential Information or trade secret information. I also agree that I will not induce or encourage or attempt to wrongfully induce or encourage any Business Partner to cease doing business with ADP or materially alter their business relationship with ADP.

c.     Vendors: I agree that during my Severance Period and for a period of twelve (12) months following my Severance Period, I will not induce or encourage or attempt to



wrongfully induce or encourage any Vendor to cease doing business with ADP or materially alter its business relationship with ADP.

5.     Non-Solicitation of Employees. I agree that during my Severance Period and for a period of twelve (12) months following my Severance Period, I will not, directly or indirectly, hire, solicit, recruit, or encourage to leave ADP, any current employees of ADP or hire, solicit, recruit, or contract with employees who terminate their employment with ADP within twelve (12) months following my Severance Period.

6.     Non-Disclosure and Non-Use of Confidential Information and Trade Secrets. I will not at any time following the termination of my employment with ADP access, disclose, use, reproduce, distribute, or otherwise disseminate ADP’s Confidential Information or trade secrets or take any action causing, or fail to take any action necessary in order to prevent, any such information to lose its character or cease to qualify as Confidential Information or a trade secret. I will not comment publicly or publish written materials on the unique manner in which ADP operates its business without the express written consent of the Chief Legal Officer or his designee, including but not limited to comments to members of the press and media, other members of the public, on social media or in books or articles of any kind. I agree to inquire with ADP if I have any questions about whether I am authorized or required to access, use, reproduce, distribute, or otherwise disseminate ADP’s Confidential Information or whether particular information is Confidential Information or a trade secret before accessing, using or disclosing such information. I understand that nothing in this Agreement prohibits me from reporting possible violations of state or federal law or regulation to any governmental agency or entity or from communicating with any such agency or entity regarding the same or otherwise participate in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information without notice to ADP. This Agreement does not limit my right to receive an award for information provided to any government agencies. I understand that nothing in this Agreement shall have the purpose or effect of concealing details related to a claim of discrimination, retaliation, or harassment. I also agree to immediately return to ADP all property and information belonging to ADP such as keys, credit cards, telephones, tools, equipment, computers, passwords, access codes, and electronic storage devices, as well as all originals, copies, or other physical embodiments of ADP’s Confidential Information or trade secrets (regardless of whether it is in paper, electronic, or other form), including any such information in any programs, business forms, manuals, correspondence, files, databases, or on computer disks or any other storage medium, including but not limited to cloud storage, whether or not owned or controlled by me or ADP (e.g., social and business networking websites, web-based email servers, Notability, or cloud storage services), immediately upon termination of my employment, and I agree not to keep, access, disclose, use, reproduce, distribute, or otherwise disseminate any copies, electronic or otherwise, of any of the foregoing. I also understand that my obligations under this paragraph, as well as the other covenants in this Restrictive Covenant Agreement, extend to my activities on the internet, including my use of business-oriented social networking sites such as LinkedIn and Facebook.

I understand that nothing in this Agreement shall in any way limit or prohibit me from engaging in any Protected Activity. Protected Activity includes: (i) filing and/or pursuing a charge, complaint, or report with, or otherwise communicating, cooperating, or participating in any investigation or proceeding that may be conducted by any federal, state or local government agency or commission, including the Securities and Exchange Commission, the Equal



Employment Opportunity Commission, the Occupational Safety and Health Administration, and the National Labor Relations Board (“Government Agencies”); and/or (ii) discussing or disclosing information about unlawful acts in the workplace, such as harassment, retaliation, or discrimination or any other conduct that I have reason to believe is unlawful. I understand that I may engage in Protected Activity voluntarily. I also understand that I do not have to seek approval from ADP prior to engaging in any Protected Activity and I do not have to notify ADP after I have engaged in any Protected Activity. Notwithstanding the foregoing, I agree to take all reasonable precautions to prevent any unauthorized use or disclosure of any Company trade secrets, proprietary information, or confidential information that does not involve unlawful acts in the workplace, possible securities law violations, or the activity otherwise protected herein. I further understand that Protected Activity does not include the disclosure of any information that I obtained through a communication that was subject to the Company’s attorney-client privilege, unless disclosure of that information would otherwise be permitted by an attorney pursuant to 17 C.F.R. Section 205.3(d)(2), applicable state attorney conduct rules, or otherwise. In addition, pursuant to the Defend Trade Secrets Act of 2016, I understand that an individual will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made in confidence to a federal, state, or local government official (directly or indirectly) or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if (and only if) such filing is made under seal. In addition, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the individual’s attorney and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order. I understand that nothing in this Agreement limits my right to receive an award for information provided to any governmental agency. Finally, nothing in this Agreement constitutes a waiver of any rights I may have under the Sarbanes-Oxley Act or Section 7 of the National Labor Relations Act (“NLRA”). For purposes of clarity, nothing in this Agreement shall be interpreted to impair or limit my participation in any legally protected activities, such as (i) forming, joining, or supporting labor unions, (ii) bargaining collectively through representatives of employees’ choosing, (iii) discussing wages, benefits, or terms and conditions of employment, and (iv) discussing, or raising complaints about, working conditions for the purpose of mutual aid or protection of my or the Company’s other current or former employees, to the extent such activities are protected by Section 7 of the NLRA. I understand that nothing in the Agreement shall limit or prohibit me from engaging in any protected conduct set forth in this section.

7.     Prior Agreements and Disclosure of Agreement to Third Parties. I agree to provide a copy of this Restrictive Covenant Agreement to any subsequent employer, person, or entity to which I intend to provide services that may conflict with any of my obligations in this Restrictive Covenant Agreement prior to engaging in any such activities and to provide ADP in writing the name and address of any such employer, person, or entity and a description of the services I intend to provide prior to engaging in any such activities. I agree that ADP may also provide a copy of this Restrictive Covenant Agreement or a description of its terms to any Client, subsequent employer, or other third party at any time as it deems necessary to protect its interests, and I agree to indemnify ADP against any claims and hold ADP harmless from any losses, costs, attorneys’ fees, expenses, fees, and damages arising out of my failure to comply with this paragraph or ADP’s providing a copy of this Agreement or a description of its terms to any Client, subsequent employer, or other third party.



8.     Severability and Reformation. I agree if any particular paragraph, subparagraph, phrase, word, or other portion of this Restrictive Covenant Agreement is determined by an appropriate court to be invalid or unenforceable as written, it shall be modified as necessary to be made valid or enforceable, and such modification shall not affect the remaining provisions of this Restrictive Covenant Agreement, or if it cannot be modified to be made valid or enforceable, then it shall be severed from this Restrictive Covenant Agreement, and all remaining terms and provisions shall remain enforceable. As it relates to the practice of law, this Restrictive Covenant Agreement should be interpreted consistent with the limitations imposed by the New Jersey Rules of Professional Conduct and/or the Model Rules of Professional Conduct (or similar rules in other jurisdictions), including RPCs 5.6, 1.9 and 1.6. If any provision in this Agreement causes the acknowledgment of the Agreement to violate any of the above-referenced RPCs as it relates to the practice of law, such provision(s) will be deemed void and severed from the Agreement.

9.     Choice of Law, Venue, and Jurisdiction. The interpretation, validity, and enforcement of this Restrictive Covenant Agreement will be governed by the laws of the State of New Jersey, without regard to any conflicts of law principles that require the application of the law of another jurisdiction. I agree that any action by me to challenge the enforceability of this Restrictive Covenant Agreement must be brought or litigated exclusively in the appropriate state or federal court located in the State of New Jersey. I also agree that any action by ADP to enforce this Restrictive Covenant Agreement, as well as any related disputes or litigation related to this Restrictive Covenant Agreement, may, but does not have to, be brought in the appropriate state or federal court located in the State of New Jersey. I agree and consent to the personal jurisdiction and venue of the federal or state courts of New Jersey for resolution of any disputes or litigation arising under or in connection with this Restrictive Covenant Agreement or any challenge to this Restrictive Covenant Agreement and waive any objections or defenses to personal jurisdiction or venue in any such proceeding before any such court.

10.     Survival. All non-competition, non-solicitation, non-disclosure and non-use, non- recruiting, intellectual property, and Restrictive Covenant Agreement disclosure obligations under paragraphs four (4) through seven (7) of this Restrictive Covenant Agreement shall survive the termination of my employment for any reason and with or without cause, and no dispute regarding any other provisions of the Restrictive Covenant Agreement or regarding my employment or the termination of my employment shall prevent the operation and enforcement of these obligations.

11.     Relief, Remedies, and Enforcement. I acknowledge that ADP is engaged in a highly competitive business, and the covenants and restrictions contained in this Restrictive Covenant Agreement, including the geographic and temporal restrictions, are reasonably designed to protect ADP’s legitimate business interests, including ADP goodwill and client relations, Confidential Information and trade secrets, and the specialized skills and knowledge gained by me and ADP’s other employees during our employment. I acknowledge and agree that a breach of any provision of this Restrictive Covenant Agreement by me will cause serious and irreparable damage to ADP that will be difficult to quantify and for which a remedy at law for monetary damages alone may not be adequate. Accordingly, I agree that if ADP should bring an action to enforce its rights under this Restrictive Covenant Agreement and ADP establishes that I have breached or threatened to breach any of my obligations under this Restrictive Covenant



Agreement, ADP shall be entitled, in addition to all remedies otherwise available in law or equity, to a temporary restraining order, a preliminary injunction, and a permanent injunction enjoining such breach or threatened breach in any court of competent jurisdiction without the necessity of posting a surety bond, as well as an equitable accounting of all profits or benefits arising out of any violation of this Restrictive Covenant Agreement, and ADP shall be entitled to cease to pay or provide any further benefits under the Automatic Data Processing, Inc. Corporate Officer Severance Plan to me and I will, upon ten (10) days’ prior written demand by ADP, promptly reimburse ADP any benefits already paid or provided under the Automatic Data Processing, Inc. Corporate Officer Severance Plan to me since the date of such breach. I also agree that nothing in this Restrictive Covenant Agreement shall be construed to prohibit ADP from pursuing any and all other legal or equitable remedies available to it for breach of any of the provisions of this Restrictive Covenant Agreement, including the disgorgement of any profits, bonuses, equity, commissions, or fees realized by me, any subsequent employers, any business owned or operated by me or to which I provide services, or any of my agents, heirs, or assigns. I also agree that that the knowledge, skills, and abilities I possess at the time of commencement of my employment are sufficient to permit me to earn a livelihood satisfactory to me without violating any provision of paragraphs four (4) through seven (7) above, for example, by using such knowledge, skills, and abilities, or some of them, in the service of business that is not competitive with ADP. I further agree to pay any and all legal fees, including without limitation, all attorneys’ fees, court costs, and any other related fees and/or costs incurred by ADP in enforcing this Restrictive Covenant Agreement.

12.     Tolling. The restricted time periods in paragraphs four (4) through six (6) above shall be tolled during any time period that I am in violation of such covenants, as determined by a court of competent jurisdiction, so that ADP may realize the full benefit of its bargain. This tolling shall include any time period during which litigation is pending, but during which I have continued to violate such protective covenants and a court has declined to enjoin such conduct or I have failed to comply with any such injunction.

13.     Entire Agreement and Validity of Terms. I agree that I do not rely, and have not relied, upon any representation or statement not set forth herein by ADP or any of ADP's agents, representatives, or attorneys, and that this Restrictive Covenant Agreement may be changed only by a subsequent agreement in writing signed by both parties. I understand that I may have an existing agreement(s) with ADP, through acquisition of a prior employer or otherwise, that may include the same or similar covenants as those in this Restrictive Covenant Agreement, and acknowledge that this Restrictive Covenant Agreement is meant to supplement any such agreement(s) such that the covenants in the agreements that provide ADP with the greatest protection enforceable under applicable law shall control, and that the parties do not intend to create any ambiguity or conflict through the execution of this Restrictive Covenant Agreement that would release me from the obligations I have assumed under the protective covenants in any of these agreements.

14.     Electronic Signature. I agree that ADP may enforce this Restrictive Covenant Agreement with a copy for which I have provided an electronic signature.

15.     Assignment and Successorship. This Restrictive Covenant Agreement and ADP’s rights and obligations hereunder may be assigned by ADP and shall inure to the benefit of and shall be enforceable by any such assignee, as well as any of ADP’s successors in interest. This Restrictive



Covenant Agreement and my rights and obligations may not be assigned by me, but are binding upon my heirs, administrators, executors, and personal representatives.

16.     Waiver. ADP’s waiver of a breach of any provision of this Restrictive Covenant Agreement in any particular instance shall not be deemed to be a waiver of any other breach in any other instance and/or of ADP’s other rights at law, in equity, or under this Restrictive Covenant Agreement. ADP’s failure to take action against any other employee for similar breaches shall not operate as a wavier by ADP of a breach as to me. Any waiver by ADP of any breach of this Restrictive Covenant Agreement by me shall not be effective unless in writing signed by a Corporate Officer of ADP, and no such waiver with regards to me or any other person under a similar agreement shall operate or be construed as a waiver of the same type of breach or any other breach on a subsequent occasion by me or any other person or entity.

17.     Jury Trial Waiver. I agree that, to the fullest extent permitted by law, each party waives any right to trial by jury with respect to any proceeding arising out of or relating to this Restrictive Covenant Agreement.

18.     Opportunity to Review. I agree that I have read this Restrictive Covenant Agreement before signing it, understand its terms, and that I have had the opportunity to have legal counsel review this agreement, prior to signing it, and I acknowledge that I have not been forced or coerced in any manner to sign this Restrictive Covenant Agreement and do so of my own free will.






IN WITNESS WHEREOF, I have executed this Restrictive Covenant Agreement as of the date set forth below.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation Basis of Presentation
The accompanying Consolidated Financial Statements and footnotes thereto of Automatic Data Processing, Inc., its subsidiaries and variable interest entity (“ADP” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Consolidated Financial Statements and footnotes thereto are unaudited. In the opinion of the Company’s management, the Consolidated Financial Statements reflect all adjustments, which are of a normal recurring nature, that are necessary for a fair presentation of the Company’s interim financial results.

The Company has a grantor trust, which holds the majority of the funds provided by its clients pending remittance to employees of those clients, tax authorities, and other payees. The Company is the sole beneficial owner of the trust. The trust meets the criteria in Accounting Standards Codification (“ASC”) 810, “Consolidation” to be characterized as a variable interest entity (“VIE”). The Company has determined that it has a controlling financial interest in the trust because it has both (1) the power to direct the activities that most significantly impact the economic performance of the trust (including the power to make all investment decisions for the trust) and (2) the right to receive benefits that could potentially be significant to the trust (in the form of investment returns) and, therefore, consolidates the trust. Further information on these funds and the Company’s obligations to remit to its clients’ employees, tax authorities, and other payees is provided in Note 7, “Corporate Investments and Funds Held for Clients.” 
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the assets, liabilities, revenue, expenses, and accumulated other comprehensive income that are reported in the Consolidated Financial Statements and footnotes thereto. Actual results may differ from those estimates. Interim financial results are not necessarily indicative of financial results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2024 (“fiscal 2024”). Certain amounts from the prior year's financial statements have been reclassified in order to conform to the current year's presentation.

Revenue Revenue
Based upon similar operational and economic characteristics, the Company’s revenues are disaggregated by its three business pillars: Human Capital Management (“HCM”), HR Outsourcing (“HRO”), and Global Solutions (“Global”), with separate disaggregation for PEO zero-margin benefits pass-through revenues and client funds interest revenues. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors.

The following tables provide details of revenue by our business pillars, and include a reconciliation to the Company’s reportable segments:

Contract Balances

The timing of revenue recognition for HCM, HRO and Global is consistent with the invoicing of clients, as invoicing occurs in the period the services are provided. Therefore, the Company does not recognize a contract asset or liability resulting from the timing of revenue recognition and invoicing.

Changes in deferred revenues related to set up fees for the six months ended December 31, 2024 were as follows:

Acquisition

Dec. 31, 2024
Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]  
Acquisition Acquisition
In October 2024, the Company acquired WorkForce Software, a premier workforce management solutions provider that specializes in supporting large, global enterprises, utilizing cash on hand. The results of WorkForce Software will be reported within the Company’s Employer Services segment. Pro forma information has not been presented because the effect of the acquisition is not material to the Company's consolidated financial results.

The following table reconciles the purchase price to the cash paid for the acquisition, net of cash acquired:
Purchase price$1,173.1 
Less: cash acquired(12.5)
Cash paid for acquisition of business, net of cash acquired$1,160.6 

The preliminary allocation of the purchase price is based upon estimates and assumptions that are subject to change within the measurement period, which is one year from the acquisition date. The primary areas of the purchase price allocation that are not yet finalized relate to the measurement of certain assets and liabilities, including identifiable intangible assets, and the finalization of net working capital items included in the purchase price allocation. Accordingly, the measurement period for such purchase price allocations will end when the information becomes available but will not exceed twelve months from the date of acquisition.

The acquisition was accounted for using the acquisition method of accounting. The Company recognized assets acquired and liabilities assumed at their fair value as of the date of acquisition, with the excess recorded to goodwill. The preliminary purchase price allocation for WorkForce Software is as follows:
Cash$12.5 
Accounts receivable, net of allowance for doubtful accounts20.0 
Identifiable intangible assets (1)417.0 
Goodwill846.4 
All other assets21.9 
Total assets acquired$1,317.8 
Deferred revenue$39.6 
Deferred income taxes46.6 
All other liabilities58.5 
Total liabilities assumed$144.7 
Total net assets acquired$1,173.1 

(1) Intangible assets are recorded at estimated fair value, as determined by management based on available information which includes an estimated valuation by an independent third-party. The fair values assigned to identifiable intangible assets were determined through the use of the income approach, specifically the relief from royalty and the multi-period excess earnings methods. The major assumptions used in arriving at the estimated identifiable intangible asset values included management’s estimates of future cash flows, discounted at an appropriate rate of return which are based on the weighted average cost of capital for both the Company and other market participants, projected customer attrition rates, as well as applicable royalty rates for comparable assets. The useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to the future cash flows. The estimated fair value of intangible assets and related useful lives as included in the estimated purchase price allocation include:

Estimated Fair ValueEstimated Useful Life
(in years)
Technology$200.0 7
Customer/Partner relationships$210.0 8

Leases Leases
The Company records leases on the Consolidated Balance Sheets as operating lease right-of-use (“ROU”) assets, records the current portion of operating lease liabilities within accrued expenses and other current liabilities and, separately, records long-term operating lease liabilities. The difference between total ROU assets and total lease liabilities is primarily attributable to prepayments of our obligations and the recognition of various lease incentives.

The Company has entered into operating lease agreements for facilities and equipment. The Company's leases have remaining lease terms of up to approximately eleven years.

Short-term Financing Short-term Financing
The Company has a $4.55 billion, 364-day credit agreement that matures in June 2025 with a one year term-out option. The Company also has a $2.25 billion, five year credit facility that matures in June 2028 that contains an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. In addition, the Company also has a five year, $3.5 billion credit facility maturing in June 2029 that contains an accordion feature under which the aggregate commitment can be increased by $500 million, subject to the availability of additional commitments. The interest rate applicable to committed borrowings is tied to SOFR, the effective federal funds rate, or the prime rate depending on the notification provided by the Company to the syndicated financial institutions prior to borrowing. The Company is also required to pay facility fees on the credit agreements. The primary uses of the credit facilities are to provide liquidity to the commercial paper program and funding for general corporate purposes, if necessary. The Company had no borrowings through December 31, 2024 under the credit agreements.

The Company's U.S. short-term funding requirements related to client funds are sometimes obtained on an unsecured basis through the issuance of commercial paper, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. This commercial paper program provides for the issuance of up to $10.3 billion in aggregate maturity value. The Company’s commercial paper program is rated A-1+ by Standard & Poor’s, Prime-1 (“P-1”) by Moody’s and F1+ by Fitch. These ratings denote the highest quality commercial paper securities. Maturities of commercial paper can range from overnight to up to 364 days. At December 31, 2024 and June 30, 2024, the Company had no commercial paper borrowing outstanding. Details of the borrowings under the commercial paper program are as follows:

The Company’s U.S., Canadian and United Kingdom short-term funding requirements related to client funds obligations are sometimes obtained on a secured basis through the use of reverse repurchase agreements, which are collateralized principally by government and government agency securities, rather than liquidating previously-collected client funds that have already been invested in available-for-sale securities. These agreements generally have terms ranging from overnight to up to five business days. At December 31, 2024, the Company had no outstanding obligations related to reverse repurchase agreements. At June 30, 2024, the Company had $385.4 million of outstanding obligations related to reverse repurchase agreements which were fully paid in early July 2024. The Company has $7.3 billion available on a committed basis under the U.S. reverse repurchase agreements. Details of the reverse repurchase agreements are as follows:

Debt Debt
The Company issued four series of fixed-rate notes with staggered maturities of 7 and 10 years totaling $4.0 billion (collectively the “Notes”). The Notes are senior unsecured obligations, and interest is payable in arrears, semi-annually.
During the first quarter ended September 30, 2024, the Company issued $1.0 billion of senior notes due in 2034 bearing a fixed interest rate of 4.450%. In connection with the senior notes issuance, the Company terminated several derivative contracts in place to hedge exposure in changes in benchmark interest rates for the senior notes issued with an aggregate notional amount totaling $1.0 billion (of which $400.0 million were executed during the three months ended September 30, 2024 and $600.0 million were executed on the day of issuance). Since these derivative contracts were classified as cash flow hedges, the unamortized loss of $12.5 million was deferred in accumulated other comprehensive income and will be amortized to earnings over the life of the issued Notes as the interest payments are made.
The principal amounts and associated effective interest rates of the Notes and other debt as of December 31, 2024 and June 30, 2024, are as follows:

A.  Stock-based Compensation Plans

The Company's share-based compensation consists of stock options, time-based restricted stock, time-based restricted stock units, performance-based restricted stock, and performance-based restricted stock units. The Company also offers an employee stock purchase plan for eligible employees. Beginning in September 2022, the Company discontinued granting stock options, time-based restricted stock and performance-based restricted stock. Any such future awards will be grants of time-based restricted stock units and/or performance-based restricted stock units, depending on employee eligibility. Time-based restricted stock unit awards and performance-based restricted stock unit awards granted to employees with a home country of the United States are settled in stock, and for awards granted to employees with a home country outside the United States are generally settled in cash.

The Company currently utilizes treasury stock to satisfy stock option exercises, issuances under the Company's employee stock purchase plan, and restricted stock units. From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase program. The Company repurchased 0.9 million and 1.1 million shares in the three months ended December 31, 2024 and 2023, respectively, and repurchased 2.4 million and 2.1 million shares in the six months ended December 31, 2024 and 2023. The Company considers several factors in determining when to execute share repurchases, including, among other things, actual and potential acquisition activity, cash balances and cash flows, issuances due to employee benefit plan activity, and market conditions.
The following table represents pre-tax stock-based compensation expense for the three and six months ended December 31, 2024 and 2023, respectively:

Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
The effective tax rate for the three months ended December 31, 2024 and 2023 was 23.6% and 23.2%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities in the three months ended December 31, 2023, partially offset by a higher excess tax benefit on stock-based compensation in the three months ended December 31, 2024.

The effective tax rate for the six months ended December 31, 2024 and 2023 was 23.1% and 22.3%, respectively. The increase in the effective tax rate is primarily due to a benefit for adjustments to prior year tax liabilities, lower reserves for uncertain tax positions and a valuation allowance release in the six months ended December 31, 2023.

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies Commitments and Contingencies
In May 2020, a putative class action complaint was filed against ADP, TotalSource and related defendants in the U.S. District Court, District of New Jersey. The complaint asserts violations of the Employee Retirement Income Security Act of 1974 (“ERISA”) in connection with the ADP TotalSource Retirement Savings Plan’s fiduciary administrative and investment decision-making. The complaint seeks statutory and other unspecified monetary damages, injunctive relief and attorney’s fees. The Company is unable to estimate any reasonably possible loss, or range of loss, with respect to this matter. The Company is vigorously defending against this lawsuit.

The Company is subject to various claims, litigation, and regulatory compliance matters in the normal course of business. When a loss is considered probable and reasonably estimable, the Company records a liability in the amount of its best estimate for the ultimate loss. Management currently believes that the resolution of these claims, litigation and regulatory compliance matters against us, individually or in the aggregate, will not have a material adverse impact on our consolidated results of operations, financial condition or cash flows. These matters are subject to inherent uncertainties and management's view of these matters may change in the future.

It is not the Company’s business practice to enter into off-balance sheet arrangements. In the normal course of business, the Company may enter into contracts in which it makes representations and warranties that relate to the performance of the Company’s services and products. The Company does not expect any material losses related to such representations and warranties.

Interim Financial Data by Segment Interim Financial Data by Segment
Based upon similar economic and operational characteristics, the Company’s strategic business units have been aggregated into the following two reportable segments: Employer Services and PEO Services. The primary components of the “Other” segment are certain corporate overhead charges and expenses that have not been allocated to the reportable segments, including corporate functions, costs related to transformation, severance costs, non-recurring gains and losses, the elimination of intercompany transactions, interest expense and corporate interest income. Certain revenues and expenses are charged to the reportable segments at a standard rate for management reasons. Other costs are recorded based on management responsibility.

Accounting Standards Update and Change in Accounting Principle [Abstract]  
Basis of Presentation Basis of Presentation
The accompanying Consolidated Financial Statements and footnotes thereto of Automatic Data Processing, Inc., its subsidiaries and variable interest entity (“ADP” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Consolidated Financial Statements and footnotes thereto are unaudited. In the opinion of the Company’s management, the Consolidated Financial Statements reflect all adjustments, which are of a normal recurring nature, that are necessary for a fair presentation of the Company’s interim financial results.

The Company has a grantor trust, which holds the majority of the funds provided by its clients pending remittance to employees of those clients, tax authorities, and other payees. The Company is the sole beneficial owner of the trust. The trust meets the criteria in Accounting Standards Codification (“ASC”) 810, “Consolidation” to be characterized as a variable interest entity (“VIE”). The Company has determined that it has a controlling financial interest in the trust because it has both (1) the power to direct the activities that most significantly impact the economic performance of the trust (including the power to make all investment decisions for the trust) and (2) the right to receive benefits that could potentially be significant to the trust (in the form of investment returns) and, therefore, consolidates the trust. Further information on these funds and the Company’s obligations to remit to its clients’ employees, tax authorities, and other payees is provided in Note 7, “Corporate Investments and Funds Held for Clients.” 
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the assets, liabilities, revenue, expenses, and accumulated other comprehensive income that are reported in the Consolidated Financial Statements and footnotes thereto. Actual results may differ from those estimates. Interim financial results are not necessarily indicative of financial results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2024 (“fiscal 2024”). Certain amounts from the prior year's financial statements have been reclassified in order to conform to the current year's presentation.

(1) Intangible assets are recorded at estimated fair value, as determined by management based on available information which includes an estimated valuation by an independent third-party. The fair values assigned to identifiable intangible assets were determined through the use of the income approach, specifically the relief from royalty and the multi-period excess earnings methods. The major assumptions used in arriving at the estimated identifiable intangible asset values included management’s estimates of future cash flows, discounted at an appropriate rate of return which are based on the weighted average cost of capital for both the Company and other market participants, projected customer attrition rates, as well as applicable royalty rates for comparable assets. The useful lives for intangible assets were determined based upon the remaining useful economic lives of the intangible assets that are expected to contribute directly or indirectly to the future cash flows. The estimated fair value of intangible assets and related useful lives as included in the estimated purchase price allocation include:
