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”). Intercompany balances and transactions have been eliminated in consolidation. 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, revenues, expenses, and 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, 2025 (“fiscal 2025”). 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 as follows: Human Capital Management (“HCM”), HR Outsourcing (“HRO”), and Global Solutions (“Global”), with separate disaggregation for PEO zero-margin benefits pass-through revenues and client fund 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 the Company's revenues and includes a reconciliation to the Company’s reportable segments:

Contract Balances

The timing of revenue recognition for our HCM, HRO and Global Solutions 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 nine months ended March 31, 2026 were as follows:

Contract Liability
Contract liability, July 1, 2025			$	520.2
Recognition of revenue included in beginning of year contract liability			(107.0)
Contract liability, net of revenue recognized on contracts during the period			108.9
Currency translation adjustments			1.0
Contract liability, March 31, 2026			$	523.1

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 are 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			$	1,170.8
Less: cash acquired			(12.5)
Cash paid for acquisition of business, net of cash acquired			$	1,158.3

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 purchase price allocation for WorkForce Software is as follows:

Cash			$	12.5
Accounts receivable, net of allowance for doubtful accounts			20.0
Identifiable intangible assets (1)			292.0
Goodwill			885.8
Deferred income taxes, net of valuation allowance			45.9
All other assets			14.8
Total assets acquired			$	1,271.0
Deferred revenue			$	39.6
All other liabilities			60.6
Total liabilities assumed			$	100.2
Total net assets acquired			$	1,170.8

(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 purchase price allocation include:

			Estimated Fair Value						Estimated Useful Life (in years)
Technology			$	115.0					7
Customer/Partner relationships			$	170.0					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.

Shares that could potentially dilute basic EPS in the future include outstanding share-based compensation awards, which are discussed in Note 12. For the three and nine months ended March 31, 2026, there were 0.6 million shares excluded from the calculation of diluted EPS because their inclusion would have been anti-dilutive. For the three and nine months ended March 31, 2025, there were no shares excluded from the calculation of diluted EPS.

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:

			Three Months Ended												Nine Months Ended
			March 31,												March 31,
			2026						2025						2026						2025
Operating lease cost			$	30.7					$	27.4					$	92.7					$	82.3

						(4,387.6)						(4,179.8)
Intangible assets, net						$	1,640.6					$	1,603.0

Other intangibles consist primarily of purchased rights, purchased content, trademarks and trade names (acquired directly or through acquisitions). All intangible assets have finite lives and, as such, are subject to amortization. The weighted average remaining useful life of the intangible assets is 6 years (6 years for software and software licenses, 5 years for customer contracts and lists, and 3 years for other intangibles). Amortization of intangible assets was $96.8 million and $96.3 million for the three months ended March 31, 2026 and 2025, respectively, and $288.0 million and $286.0 million for the nine months ended March 31, 2026 and 2025, respectively.

Note 10. Short-term Financing

The Company has a $4.6 billion, 364-day credit agreement that matures in June 2026 with a one year term-out option. The Company also has a $3.5 billion, five year credit facility that matures 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. In addition, the Company also has a $2.5 billion five year credit facility maturing in June 2030 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 March 31, 2026 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 $10.6 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. As of March 31, 2026, the Company had no commercial paper outstanding. As of June 30, 2025, the Company had $4.8 billion of commercial paper outstanding, which was repaid in early July 2025. Details of the borrowings under the commercial paper program are as follows:

			Three Months Ended												Nine Months Ended
			March 31,												March 31,
			2026						2025						2026						2025
Average daily borrowings (in billions)			$	3.8					$	3.3					$	4.2					$	4.2
Weighted average interest rates			3.7		%				4.4		%				4.1		%				4.9		%
Weighted average maturity (approximately in days)			2 days						2 days						2 days						2 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. As of March 31, 2026, the Company had no outstanding obligations related to reverse repurchase agreements. As of June 30, 2025, the Company had $38.4 million of outstanding obligations related to reverse repurchase agreements. The Company has $7.5 billion available on a committed basis under the U.S. reverse repurchase agreements. Details of the reverse repurchase agreements are as follows:

			Three Months Ended												Nine Months Ended
			March 31,												March 31,
			2026						2025						2026						2025
Average outstanding balances (in billions)			$	1.1					$	0.9					$	3.3					$	2.8
Weighted average interest rates			3.8		%				4.1		%				4.2		%				4.9		%

Note 11. Debt

The Company issued four series of fixed-rate notes with staggered maturities of 7 and 10 years at the time of issuance totaling $4.0 billion (collectively the “Notes”). The Notes are senior unsecured obligations, and interest is payable in arrears, semi-annually.

The principal amounts and associated effective interest rates of the Notes and other debt as of March 31, 2026 and June 30, 2025, are as follows:

Debt instrument						Effective Interest Rate						March 31, 2026						June 30, 2025
Fixed-rate 1.700% notes due May 15, 2028						1.85%						1,000.0						1,000.0
Fixed-rate 1.250% notes due September 1, 2030						1.83%						1,000.0						1,000.0
Fixed-rate 4.750% notes due May 8, 2032						4.95%						1,000.0						1,000.0
Fixed-rate 4.450% notes due September 9, 2034						4.75%						1,000.0						1,000.0
Other												2.1						2.9

Less: current portion (a)												(1.1)						(1.0)
Less: unamortized discount and debt issuance costs												(23.7)						(27.2)
Total long-term debt												$	3,977.3					$	3,974.7

(a) - Current portion of long-term debt as of March 31, 2026 is included within accrued expenses and other current liabilities on the Consolidated Balance Sheets.

The effective interest rates for the Notes include the interest on the Notes and amortization of the discount and debt issuance costs.

As of March 31, 2026, the fair value of the Notes, based on Level 2 inputs, was $3,821.8 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 2025.

Note 12. Employee Benefit Plans

A. Stock-based Compensation Plans

The Company's share-based compensation plan 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 granted September 2022 and after 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 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 awards. From time to time, the Company may repurchase shares of its common stock under its authorized share repurchase program. The Company repurchased 2.6 million and 1.0 million shares in the three months ended March 31, 2026 and 2025, respectively, and repurchased 5.7 million and 3.4 million shares in the nine months ended March 31, 2026 and 2025, respectively. 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 nine months ended March 31, 2026 and 2025, respectively:

			Three Months Ended												Nine Months Ended
			March 31,												March 31,
			2026						2025						2026						2025
Operating expenses			$	7.4					$	9.0					$	24.5					$	27.3
Selling, general and administrative expenses			36.2						45.5						132.9						147.4
Research and development			7.4						8.3						25.5						27.8
Total stock-based compensation expense			$	51.0					$	62.8					$	182.9					$	202.5

B. Pension Plans

The components of net pension (income)/expense were as follows:

			Three Months Ended																		Nine Months Ended
			March 31,																		March 31,
			2026						2025																		2026						2025
Service cost – benefits earned during the period			$	2.0					$	1.5																	$	5.9					$	4.5
Interest cost on projected benefits			21.7						21.8																		65.2						65.5
Expected return on plan assets			(28.3)						(29.0)																		(84.9)						(87.0)
Net amortization and deferral			0.7						0.7																		2.2						2.2
Net pension (income)/expense			$	(3.9)					$	(5.0)																	$	(11.6)					$	(14.8)

Note 13. Income Taxes

The effective tax rate for the three months ended March 31, 2026 and 2025 was 23.7% and 23.0%, respectively. The increase in the effective tax rate is primarily due to an increase in uncertain tax positions and a lower excess tax benefit on stock-based compensation in the three months ended March 31, 2026 as compared to the three months ended March 31, 2025.

The effective tax rate for the nine months ended March 31, 2026 and 2025 was 23.2% and 23.1%, respectively. The increase in the effective tax rate is primarily due to a lower excess tax benefit on stock-based compensation offset by a decrease in uncertain tax positions for the nine months ended March 31, 2026 as compared to the nine months ended March 31, 2025.

Note 14. Commitments and Contingencies

As of March 31, 2026, the Company has purchase commitments of approximately $2,226.8 million, including obligations related to software license agreements, third-party software services and purchase and maintenance agreements on our software, equipment, and other assets, of which $67.9 million relates to the three months ending June 30, 2026, $1,042.7 million relates to the years ending June 30, 2027 through 2028, $998.1 million relates to the years ending June 30, 2029 through 2031, and the remaining relates to fiscal years thereafter.

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 unspecified monetary relief, 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. 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.

The Company's Chief Operating Decision Maker ("CODM") is the Chief Executive Officer. For each reportable segment, the CODM uses earnings before income taxes, including plan-to-actual and forecast-to-actual results, to assess segment performance and allocate resources (including personnel and capital resources) amongst its strategic business units. The CODM does not review assets at the reportable segment level, hence segment disclosure relating to total assets has not been provided.

The following tables present the Company's revenues, significant segment expenses, and earnings before income taxes by reportable segment:
