2025 Proxy Statement Summary

Advisory Resolution to Approve Executive Compensation (Proposal 2)

Consistent with the stockholders’ advisory vote at our 2023 Annual Meeting of Stockholders, we determined to hold the advisory say-on-pay vote to approve our named executive officer (“NEO”) compensation on an annual basis. Therefore, we are asking our stockholders to approve, on an advisory basis, our named executive officer compensation for fiscal year 2025. Our stockholders will have the opportunity to approve, on an advisory basis, our NEO compensation for fiscal year 2026 at the 2026 Annual Meeting of Stockholders.

The board of directors recommends a vote FOR this resolution because it believes that the policies and practices described in the “Compensation Discussion and Analysis” section beginning on page 40 of this proxy statement are effective in achieving the company’s goals of linking pay to performance and levels of responsibility, encouraging our executive officers to remain focused on both short-term and long-term financial, client satisfaction, transformation, paperless and human capital management (“HCM”) goals

of the company, and aligning the interests of our executive officers with the interests of our stockholders by linking executive performance to stockholder value.

At our 2024 Annual Meeting of Stockholders, our stockholders approved the compensation of our fiscal year 2024 NEOs by a vote of approximately 90% in favor.

Ratification of the Appointment of Auditors (Proposal 3)

We are asking our stockholders to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2026. A summary of fees paid to Deloitte & Touche LLP for services provided in fiscal years 2025 and 2024 is provided on page 99 of this proxy statement. The board of directors recommends a vote FOR this resolution.

2025 Proxy Statement Summary

Fiscal Year 2025 Business Highlights

Our Strategic Priorities. With a large and growing addressable market, we are focused on our core growth areas and further enhancing our market position by executing on our three strategic priorities:

Our strategic priorities
| Lead with best-in-class HCM technology
| Provide unmatched Expertise and outsourcing
| Benefit our clients with our Global scale

Fiscal year 2025 reflected continued strength, growth and momentum at ADP:

HIGHLIGHTS |  | STOCKHOLDER FRIENDLY ACTIONS
$20.6 billion in revenue 10% earnings per share growth to $9.98 for the year Employer Services new business bookings increased 3% to a new record of $2.1 billion and worldwide new business bookings increased 3.5% Strong Employer Services Client Retention of 92.1% Reached new, all-time high company-wide client satisfaction levels Over 1.1 million clients globally Over 42 million workers paid across 140+ countries and territories |  | $3.7 billion in cash returned to stockholders $2.4 billion dividends $1.3 billion share repurchases 50 consecutive years of dividend increases
STRATEGIC EXECUTION
Continued to lead with best-in-class HCM technology by launching a flexible, intelligent and human-centric global HCM solution that unifies HR management, payroll, workforce management, talent, and data analytics. We also continued to roll out a cross-platform solution powered by generative AI that transforms data into credible and actionable insights for clients. Continued to lean into our unmatched expertise by deploying AI tools across our sales, service, and research and development functions to improve the client experience and drive internal productivity gains. Continued to leverage our global scale by launching an integrated payroll solution for small businesses, expanding our offer in markets with exciting growth opportunities, and by acquiring payroll businesses that strengthen our capabilities in local and global payroll and HR. We also acquired WorkForce Software, which meaningfully enhanced our capabilities in the time and attendance space, allowing us to serve the broader workforce management needs of our clients.

Table of Contents

2025 Proxy Statement Summary

As a global leader in HR and payroll solutions, ADP continuously aims to solve complex business challenges for our clients and their workers. 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 see tremendous opportunity ahead as we focus on our three key strategic priorities.

In this context, ADP remained focused on delivering exceptional value to our clients in fiscal year 2025. Consistent and solid execution on our resilient business model produced strong revenue and earnings growth in fiscal year 2025. This top-line revenue growth, balanced with solid margin performance, drove earnings per share (“EPS”) growth of 10%. Other key business drivers such as new business bookings and client satisfaction (net promoter scores) also reached new record levels and our overall results, together with our focus on sound capital allocation, have served to further strengthen our business model with high levels of recurring revenue, strong operating cash flow, and a solid balance sheet.

Our capital deployment priorities remain unchanged – leverage the strength of our model to reinforce our competitive position by, first and foremost, reinvesting in
the business. We believe that balancing investments in innovative solutions, client service tools, and distribution is critical to strengthening our market-leading offerings. We supplement these investments through a disciplined approach to M&A. Our focus on delivering top-line revenue growth, while also improving the efficiency and effectiveness of our operations, is complemented by a commitment to return excess cash to stockholders through dividends and disciplined share buybacks.
As new technologies and shifting workplace dynamics continuously reshape the way people work, we support every HCM need of our clients whether that client is a small, local business or a large, global enterprise operating around the world. From HR, payroll, time and benefits to HR outsourcing, talent, compliance and retirement, our solutions span the entire employee experience from hire to retire. As we look ahead to fiscal year 2026 and beyond, we are focused on delivering healthy returns to our stockholders through strong revenue growth and margin expansion and we will continue to focus on people, as we leverage our unparalleled data insights and innovative technology to build a world of work that is smarter, easier, and more human.

Compensation Principles

We believe that compensation should be designed to create a direct link between performance and stockholder value. Five principles that guide our decisions involving executive compensation are that compensation should be:

1 | based on (i) the overall performance of the company, (ii) the performance of each executive’s business unit when applicable and (iii) each executive’s individual performance
2 | closely aligned with the short-term and long-term financial, client satisfaction, transformation, paperless and HCM objectives that build sustainable long-term stockholder value
3 | competitive, in order to attract and retain executives critical to our long-term success
4 | consistent with high standards of corporate governance and best practices
5 | designed to dampen the incentive for executives to take excessive risks or to behave in ways that are inconsistent with the company’s strategic planning processes and high ethical standards

2025 Proxy Statement Summary

2025 Compensation Highlights

Consistent with our pay for performance philosophy, the compensation of our NEOs is structured with a significant portion of their total compensation at risk and paid based on the performance of the company as a whole. Our financial performance in fiscal year 2025 impacted the compensation for all of our executive officers, not just our

NEOs, in several ways, most notably through our annual cash bonus plan and performance-based stock unit (“PSU”) program. Please refer to the “Compensation Discussion and Analysis” section on page 40 of this proxy statement, and the tables and narratives that follow on page 64 of this proxy statement, for more details concerning the compensation of our NEOs.

Key highlights of our fiscal year 2025 executive compensation program
Base salary: | Our NEOs received salary increases in fiscal year 2025 of 2%. In addition, Mr. DeSilva received a 6.2% salary increase effective January 1, 2025 in connection with his appointment as Executive Vice President, North America and Chief of Operations.
Annual cash bonus: | Fiscal year 2025 target bonuses were the same as a percentage of base salary as in fiscal year 2024 for all NEOs other than Mr. DeSilva, whose target bonus percentage of 125% reflects a blended percentage for fiscal year 2025 of 100% for the period of July 1, 2024 through December 31, 2024, and 150% effective January 1, 2025. Annual bonuses were based on the financial performance of the company as well as client satisfaction, transformation, paperless and HCM performance goals. For fiscal year 2025, our NEOs received cash bonuses at 107.1% of target.
Equity awards: | As part of our equity compensation program in fiscal year 2025, we granted our executive officers PSUs and restricted stock units (“RSUs”).

2025 Incentive Compensation Performance Metrics

Performance for all metrics, including the client satisfaction, transformation, paperless and HCM objectives under the annual cash bonus plan, are formulaically measured, based on predetermined and objectively quantifiable goals. Targets and results for our financial metrics exclude the impact of certain limited items pursuant to predetermined categories of adjustments established by the compensation and management development committee (the “committee”) at the time that targets were set.

Annual Cash Bonus Plan. The committee’s determination of incentive compensation under our annual cash bonus plan for our executive officers, including our NEOs, was based on fiscal year 2025 revenue growth, new business bookings growth, and adjusted EBIT growth as well as client satisfaction, transformation, paperless and HCM objectives.

These fiscal year 2025 goals were established consistent with the committee’s long-standing methodology in setting such goals and as such, align to the financial earnings guidance the company communicated in July 2024 for fiscal year 2025 and reflect ADP’s expectations and assumptions at that time.

2025 Proxy Statement Summary

Details with regard to non-financial objectives are provided on page 55 and the financial goals and performance results are summarized below. Each bonus measure below is expressed as a percentage-based growth goal, thus requiring correspondingly higher levels of absolute year-over-year performance delivery. For fiscal year 2025, our NEOs received cash bonuses at 107.1% of target.

Annual Cash Bonus Plan Measures |  | Plan Targets |  | Plan Results
Revenue Growth |  | 5.7% |  | 7.1%, excluding the impact of foreign currency fluctuations in excess of the fluctuations assumed in the target
New Business Bookings Growth(1) |  | 7.8% |  | 3.5%
Adjusted EBIT Growth(2) |  | 8.8% |  | 9.7%, excluding the impact of foreign currency fluctuations in excess of the fluctuations assumed in the target

1 | For fiscal year 2025, our new business bookings definition includes annualized recurring revenues anticipated from sales orders to new and existing clients for Employer Services and Professional Employer Organization (“PEO”) Services. It excludes revenue that is one-time in nature and zero-margin benefits pass-throughs.
2 | Our adjusted EBIT measure excludes the impact of taxes, certain interest expense, certain interest income, and certain other items. We continue to 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. Refer to the table in Appendix A for a reconciliation from net earnings to adjusted EBIT for fiscal years 2025 and 2024.

Long-Term Incentive Program. Performance incentive compensation under our PSU program was based on the achievement of adjusted net income growth (67% weight) and revenue excluding zero-margin benefits pass-throughs (“revenue ex-ZMPT”) growth (33% weight) for fiscal year 2025. PSU awards are also subject to a relative total shareholder return (“rTSR”) metric that may modify the final payout (by +/-20%) at the end of the respective full threeyear period based on our performance as compared to the S&P 500. Targets and results exclude the impact of certain limited items pursuant to predetermined categories of adjustments established by the committee at the time the
targets were set. For more information on the application of these performance metrics, see “Long-Term Incentive Compensation Programs” on page 56.
These financial goals for the PSU awards granted in fiscal year 2025 were established consistent with the committee's long-standing methodology in setting such goals and as such, align to the financial earnings guidance the company communicated in July 2024 for fiscal year 2025 and reflect ADP’s expectations and assumptions at that time. Each PSU measure below is expressed as a percentage-based growth goal, thus requiring correspondingly higher levels of absolute year-over-year performance delivery.

PSU Program Measures |  | Program Targets |  | Program Results
Adjusted Net Income Growth(1) |  | 7.9% |  | 10.6%, excluding the impacts of:
|  |  |  | ●Foreign currency fluctuations in excess of the fluctuations assumed in the target ●First-year impact of business acquisitions
Revenue ex-ZMPT Growth(2) |  | 5.6% |  | 6.2%, excluding the impacts of:
|  |  |  | ●Foreign currency fluctuations in excess of the fluctuations assumed in the target ●First-year impact of business acquisitions

1 | Our adjusted net income measure excludes the impact of certain one-time charges and benefits reflecting specific items that are not fundamental to our underlying business operations. Refer to the table in Appendix A for further detail on these items and a reconciliation from net earnings to adjusted net income for fiscal years 2025 and 2024.
2 | Our revenue ex-ZMPT measure is a consolidated revenue growth measure that excludes the impact of zero-margin benefits pass-throughs. Importantly, the PSU revenue metric is not duplicative of the annual cash bonus plan revenue metric due to the exclusion of zero-margin benefits pass-throughs. Refer to the table in Appendix A for further detail on this item and a reconciliation from consolidated revenue to revenue ex-ZMPT for fiscal years 2025 and 2024.

A payout percentage of 132% was achieved under our PSU program as a result of our fiscal year 2025 adjusted net income growth and revenue ex-ZMPT growth. The payout percentage of 132% applies to year 1 of the fiscal year 2025 award, year 2 of the fiscal year 2024 award, and year 3 of the fiscal year 2023 award.

In addition, the three-year rTSR performance period for the fiscal year 2023 PSU award concluded at the end of fiscal year 2025, with a final modifier performance achievement of +114.5% based on our TSR percentile rank of 68.1 relative to the S&P 500. The fiscal year 2023 PSU award achieved a final payout of 137%.

1 | Mr. DeSilva’s base salary and target annual bonus reported in the table reflect blended amounts in light of his mid-fiscal year appointment to the role of EVP, North America and Chief of Operations.
2 | Mr. Ayala’s base salary reflects the amount paid through his last day of employment of March 31, 2025. Pursuant to the terms of Mr. Ayala’s qualifying termination under the company’s Corporate Officer Severance Plan, the target annual bonus total is prorated for a period of 9 of 12 months of active service during the fiscal year.
3 | Equity amounts reflect the target grant values for fiscal year 2025. For PSUs, these amounts vary from the totals disclosed in the “Summary Compensation Table for Fiscal Year 2025” on page 64 of this proxy statement, which reflect the grant date fair value, calculated in accordance with FASB ASC Topic 718, for the performance year in which performance targets are set. Accordingly, the amounts for PSU awards in the Summary Compensation Table represent the grant date fair value of the first, second and third tranche of the target awards that were granted in fiscal years 2025, 2024 and 2023, respectively.

2025 Proxy Statement Summary

The mix of target total direct compensation (base salary, cash bonus and long-term incentive awards) for fiscal year 2025 was designed to deliver the following approximate proportions of total compensation to Ms. Black, our chief executive officer, and the other NEOs if company and

individual target levels of performance are achieved. The target pay mix below reflects the PSU target award based on the three-year target opportunity. Ms. Black’s higher proportion of at-risk compensation reflects her greater responsibility for overall company performance.

Compensation Good Governance and Best Practices

Our compensation programs reflect our strong commitment to good governance.

What we do

✓ | Pay for performance: We design our compensation programs to link pay to performance and levels of responsibility, to encourage our executive officers to remain focused on both the short-term and long-term financial, client satisfaction, transformation, paperless and HCM goals of the company and to link executive performance to stockholder value.
✓ | Annual say-on-pay vote: We hold an advisory say-on-pay vote to approve our NEO compensation on an annual basis.
✓ | Clawback policy: We maintain a rigorous Clawback Policy which exceeds Nasdaq listing requirements and allows for the recovery of both cash and equity incentive compensation from any current or former corporate officer (including any executive officer) who engages in any activity that is in conflict with or adverse to ADP’s interests, including fraud.
✓ | Stock ownership guidelines: We maintain stock ownership guidelines to encourage equity ownership by our executive officers.

✓ | Limited perquisites: We provide limited perquisites that are viewed as consistent with our overall compensation philosophy.
✓ | Double trigger change in control payments: Our Change in Control Severance Plan for Corporate Officers includes “double-trigger” provisions, such that payments of cash and vesting of equity awards occur only if termination of employment without cause or with good reason occurs during the two-year period after a change in control.
✓ | Independence of our compensation and management development committee and advisor: The compensation and management development committee of our board of directors, which is comprised solely of independent directors, utilizes the services of FW Cook as an independent compensation consultant. FW Cook reports to the committee, does not perform any other services for the company other than in connection with an annual review of competitive director compensation for the nominating/corporate governance committee of our board of directors, and has no economic or other ties to the company or the management team that could compromise their independence and objectivity.

2025 Proxy Statement Summary

What we do

✓ | Equity plan best practices: Our 2018 Omnibus Award Plan, approved by stockholders in November 2018, incorporates certain governance best practices, including a minimum vesting period of one-year (with certain limited exceptions), a minimum 100% fair market value exercise price (except for substitute awards from an acquired or merged company), no “liberal share recycling” of stock options or stock appreciation rights and no “liberal” change in control definition.

✓ | Stockholder engagement: As described below under “Fiscal Year 2025 Stockholder Engagement,” our investor engagement program promotes an active dialogue with our largest stockholders on a range of topics related to our strategy, corporate governance and executive compensation programs.

What we don’t do

✗ | No-hedging policy: We prohibit all of our directors and employees, including our executive officers, from engaging in any hedging or similar transactions involving ADP securities.
✗ | No-pledging policy: We prohibit all of our directors and employees, including our executive officers, from holding ADP securities in a margin account or pledging ADP securities as collateral for a loan.
✗ | No repricing of underwater stock options without stockholder approval: We may not lower the exercise price of any outstanding stock options or otherwise provide economic value to the holders of underwater stock options in exchange for the forfeiture of such awards without stockholder approval.

✗ | No discount stock options: The exercise price of our stock options is not less than 100% of the fair market value of our common stock on the date of grant.
✗ | No IRC Section 280G or 409A tax gross-ups: We do not provide tax gross-ups under our change in control provisions or deferred compensation programs.
✗ | No current dividends on unearned performance stock units: We do not pay dividends in respect of unearned PSUs; rather, dividend equivalents are accrued over the applicable performance period and are paid only if the units are earned and shares are issued at the end of the performance period.

✓Invited stockholders representing nearly half of our shares outstanding to discuss our strategy, corporate governance and executive compensation programs, and held meetings with stockholders representing over 20% of our shares outstanding |  | ✓Over 80 meetings held with top-50 stockholders to discuss business performance and seek overall feedback

Our Stockholder and Stakeholder Engagement Process

We value stockholder engagement and feedback as we strive to deliver strong financial performance and sustained value creation for our investors. Our ongoing investor engagement program includes outreach focused on the company’s strategy, corporate governance and executive compensation programs. In addition to management, many of these engagements include participation by certain members of our board of directors. Director participation will continue to be part of our engagement program in fiscal year 2026.

What we learn through our ongoing engagements is regularly shared with our board of directors and incorporated into our disclosures, plans and practices, as appropriate. For example, over the past year, investors have continued to seek a better understanding of ADP’s cyber, data security and artificial intelligence (“AI”) oversight and practices. Our board of directors recognizes that security

is integral to our products, our business processes and infrastructure. We have an enterprise-wide approach to security with the objectives of protecting client data and funds, and preventing security incidents that could adversely affect the confidentiality, integrity, or availability of our information systems and data that resides in those systems, while also improving our system resilience with the aim of minimizing the impact to our business when incidents do occur. Our global data privacy and governance team, in cooperation with the chief data office, is responsible for our AI ethics and governance program, which drives compliance with AI ethical principles and regulatory requirements in development and usage of AI systems, including generative AI tools. More information on these matters is available on our corporate website, at www.adp.com. To access this information, click on “About” then “Data Security” or “Data Privacy” as appropriate.

WHAT IF I HAVE TECHNICAL DIFFICULTIES OR TROUBLE ACCESSING THE VIRTUAL MEETING? |  | If you encounter any technical difficulties logging into the website (www.virtualshareholdermeeting.com/ADP2025) or during the virtual meeting, there will be a 1-800 number and international number available on the website to assist you. Technical support will be available 15 minutes prior to the start time of the virtual meeting.
HOW MANY SHARES MUST BE PRESENT TO HOLD THE MEETING? |  | The representation in person or by proxy of a majority of the issued and outstanding shares of stock entitled to vote at the meeting constitutes a quorum. Under our amended and restated certificate of incorporation, our amended and restated by-laws and under Delaware law, abstentions and “broker non-votes” are counted as present in determining whether the quorum requirement is satisfied. A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner.
HOW CAN I VOTE MY SHARES? |  | The Notice of Internet Availability of Proxy Materials instructs you on how to vote through the Internet. If you receive a paper copy of the proxy materials, you may also vote your shares by telephone or by completing, signing, dating and returning the accompanying printed proxy in the enclosed envelope, which requires no postage if mailed in the United States. Unless contrary instructions are indicated on the proxy, all shares represented by valid proxies received pursuant to this solicitation (and not revoked before they are voted) will be voted in accordance with the recommendations of our board of directors as indicated below. If you are a registered stockholder who would ordinarily be delivering your completed proxy card in person at the meeting, please follow the voting instructions that will be available on the website (www.virtualshareholdermeeting.com/ADP2025) during the 2025 Annual Meeting.
IF I HOLD SHARES IN STREET NAME, DOES MY BROKER NEED INSTRUCTIONS IN ORDER TO VOTE MY SHARES? |  | If your shares are held in “street name” (i.e., your shares are held by a bank, brokerage firm or other nominee), you must provide voting instructions to your bank or broker by the deadline provided in the materials you receive from your bank or broker. If you hold your shares in street name and you do not instruct your bank or broker as to how to vote your shares, your bank or broker may only vote your shares in its discretion on the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2026 (Proposal 3), but will not be allowed to vote your shares on any of the other proposals described in this proxy statement, including the election of directors. Under applicable Delaware law, a broker non-vote will have no effect on the outcome of any of the other proposals described in this proxy statement because the non-votes are not considered in determining the number of votes necessary for approval.

Questions and Answers About the Annual Meeting and Voting

|  | Proposal 1: The affirmative vote of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to elect a director, provided that if the number of nominees exceeds the number of directors to be elected (a situation that the company does not anticipate), the directors shall be elected by the vote of a plurality of the shares represented in person or by proxy and entitled to vote thereon. Votes may be cast in favor of or against each nominee, or a stockholder may abstain from voting. Abstentions will have the effect of a negative vote. If the number of nominees exceeds the number of directors to be elected, votes may be cast in favor of or withheld against each nominee, and abstentions will be excluded entirely and will have no effect on the vote. If your broker holds your shares, your broker is not entitled to vote your shares on this proposal without your instruction, and therefore a broker non-vote will have no effect on the outcome of this proposal. Proposal 2: The affirmative vote of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to approve the advisory resolution on executive compensation. Votes may be cast in favor of or against this proposal or a stockholder may abstain from voting. Abstentions will have the effect of a negative vote. If your broker holds your shares, your broker is not entitled to vote your shares on this proposal without your instruction, and therefore a broker non-vote will have no effect on the outcome of the advisory resolution. Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to any named executive officer and will not be binding on or overrule any decisions by the compensation and management development committee or the board of directors. Because we value our stockholders’ views, however, the compensation and management development committee and the board of directors will consider carefully the results of this advisory vote when formulating future executive compensation policy. Proposal 3: The affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to ratify the appointment of Deloitte & Touche LLP as the company’s independent registered public accounting firm for fiscal year 2026. Votes may be cast in favor of or against this proposal or a stockholder may abstain from voting. Abstentions will have the effect of a negative vote. Brokers have the authority to vote shares for which their customers did not provide voting instructions on the ratification of the appointment of Deloitte & Touche LLP, so there will be no broker non-votes for this item.

WHAT IS “HOUSEHOLDING?” |  | To reduce the expense of delivering duplicate proxy materials to stockholders who may have more than one account holding our stock but share the same address, we have adopted a procedure known as “householding.” Under this procedure, certain stockholders of record who have the same address and last name, and who do not participate in electronic delivery of proxy materials, will receive only one copy of our Notice of Internet Availability of Proxy Materials and, as applicable, any additional proxy materials that are delivered until such time as one or more of these stockholders notifies us that they want to receive separate copies. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions. If you are a registered stockholder and choose to have separate copies of our Notice of Internet Availability of Proxy Materials, proxy statement and annual report on Form 10-K mailed to you, you must “opt-out” by writing to Broadridge Financial Solutions, Inc., Householding Department, 51 Mercedes Way, Edgewood, New York, 11717 or by calling 1-866-540-7095 and we will cease householding all such disclosure documents within 30 days. If we do not receive instructions to remove your accounts from this service, your accounts will continue to be “householded” until we notify you otherwise. If you own our common stock in nominee name (such as through a broker), information regarding householding of disclosure documents should have been forwarded to you by your broker. You can also contact Broadridge Financial Solutions, Inc. at 1-866-540-7095 if you received multiple copies of the Annual Meeting materials and would prefer to receive a single copy in the future.

Proposal 1

It is expected that all nominees proposed by our board of directors will be able to serve on the board if elected. However, if before the election one or more nominees is unable to serve or for good cause will not serve (a situation that we do not anticipate), the proxy holders will vote the proxies for the remaining nominees and for substitute nominees chosen by the board of directors (unless the board reduces the number of directors to be elected).

If any substitute nominees are designated, we will file an amended proxy statement that, as applicable, identifies the substitute nominees, discloses that such nominees have consented to being named in the revised proxy statement and to serve if elected, and includes certain biographical and other information about such nominees required by the rules of the SEC.

Stockholder Approval Required

At the 2025 Annual Meeting of Stockholders, directors will be elected by the affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote thereon, provided that if the number of nominees exceeds the number of directors to be elected (a situation we do not anticipate), the directors will be elected by the vote of a plurality of the shares represented in person or by proxy and entitled to vote thereon.

Corporate Governance

The board of directors’ categorical standards of director independence are consistent with Nasdaq listing standards and are available in the company’s corporate governance principles on our corporate website at www.adp.com. To access these documents, click on “Investors,” then “Governance,” and then “Governance Documents.” The board of directors has determined that Mses. Haynesworth, Katsoudas, Keene, Lynch and Wijnberg and Messrs. Bisson, Goeckeler, Lynch, Powers and Swan meet these standards and are independent for purposes of the Nasdaq listing standards. All current members of the audit, compensation and management development, nominating/corporate governance, and corporate development and technology committees are independent.

In the ordinary course of business, the company has business relationships with certain companies in which ADP directors also serve as executive officers or on the board of directors, including for example, hardware, software, HCM and other technology services. Based on the standards described above, the board of directors has determined that none of these transactions or relationships, nor the associated amounts paid to the parties, was material or would impede the exercise of independent judgment.

It is our policy that our directors attend the Annual Meetings of Stockholders. All of our directors then in office attended our 2024 Annual Meeting of Stockholders.

During fiscal year 2025, our board of directors held ten (10) meetings. At various points throughout the fiscal year, our board meetings consist of two-day sessions so that our board has ample opportunity to evaluate and discuss our strategy, product portfolio and talent.

All of our incumbent directors attended at least 75%, in the aggregate, of the meetings of the board of directors and the committees of which they were members during the periods that they served on our board of directors during fiscal year 2025.

Executive sessions of the independent, non-management directors are held during each meeting of the committees and the board of directors. Mr. Lynch, our non-executive chair, presides at each executive session of the board of directors.

Board Leadership Structure

Our corporate governance principles do not require the separation of the roles of board chair and chief executive officer because the board believes that effective board leadership can depend on the skills and experience of, and personal interaction between, people in leadership roles. Our board of directors is currently led by Mr. Lynch, our independent, non-executive chair. Ms. Black, our chief executive officer, serves as a member of the board of directors. The board of directors believes the current leadership structure is in the best interests of the company’s stockholders at this time. Separating these positions allows

our chief executive officer to focus on developing and implementing the company’s business plans and supervising the company’s day-to-day business operations, and allows our non-executive chair to lead the board of directors in its oversight, advisory, and risk management roles. The non-executive chair is responsible for the management, development, and the effective performance of the board, and provides leadership to the board for all aspects of the board’s work, as well as engaging with major stockholders, if requested.

Corporate Governance

Board Composition and Director Succession Planning

The board takes a thoughtful approach to its composition to ensure alignment with the company’s evolving corporate strategy. We believe our board composition strikes a balanced approach to director tenure and allows the board to benefit from a mix of newer directors who bring fresh insights and seasoned directors who bring continuity and a deep understanding of ADP. We believe this mix supports both innovation and stability in guiding our complex business. We refresh our board and assess our board succession plans regularly with this balance of tenure and experience in mind. Five of our ten independent director nominees have a tenure of five years or less. As of our 2025 Annual Meeting, the average age of our twelve director nominees will be 63 years and the average tenure of our ten independent director nominees will be 5.5 years.

Our director succession planning is conducted in the context of a skillset review designed to focus on key areas of skills and experience deemed to be most helpful to driving board performance. Our nominating/corporate governance committee evaluates these desired attributes on an ongoing basis and adds new skills and qualifications as necessary in light of the company’s changing strategy and needs.

Individual director evaluations are also conducted by the nominating/corporate governance committee on an annual basis, in close coordination with our non-executive chair who supplements such evaluations with one-on-one discussions with each director.

The form of assessment used to facilitate this review is refreshed each year to ensure relevance and covers a broad array of topics relevant to individual performance such as knowledge, expertise, commitment, preparation, integrity and judgment. This process facilitates director succession planning as it helps identify opportunities to enhance individual performance and any relevant feedback is communicated to the individual director.

In addition to individual evaluations, the nominating/corporate governance committee, working with our non-executive chair, conducts a thorough evaluation at the board and committee levels to ensure the effectiveness of the directors and their ability to work as a team in the long-term interest of the company. This assessment is conducted through a questionnaire process, which is also refreshed each year, and designed to elicit feedback with respect to areas such as board/committee structure, governance, communication, culture, risk and strategy. Responses are shared and discussed with the nominating/corporate governance committee. The committee then shares the output of this process with the full board along with a series of recommendations that are subsequently implemented to improve board and committee performance, practices and procedures.

The company also has a director retirement policy in place to promote thoughtful board refreshment, as set forth in further detail under “Retirement Policy” on page 20 of this proxy statement.

Director Nomination Process

Our nominating process ensures our board consists of a well-qualified and diverse group of leaders who bring an important mix of boardroom and operating experience. When the board of directors decides to recruit a new member, or when the board of directors considers any

director candidates submitted for consideration by our stockholders, it seeks strong candidates who, ideally, meet all of its categorical standards of director independence, and who complement our identified board skillset needs. Additionally, candidates should possess the following

The nominating/corporate governance committee will not consider candidates who lack the foregoing personal characteristics.

To ensure that our board is composed of directors with sufficiently diverse and independent perspectives, our nominating/corporate governance committee considers a wide range of other factors in determining the composition of our board of directors, including diversity of thought, individual qualities such as professional experience,

skills, education and training, and a range of types of diversity, including race, gender, ethnicity, age, culture and geography.

The nominating/corporate governance committee retains a third-party search firm from time to time to identify and evaluate, as appropriate, potential nominees to the board, including in connection with the 2025 nominations of Ms. Lynch and Mr. Swan.

Nominations of candidates for our board of directors by our stockholders for consideration at our 2026 Annual Meeting of Stockholders are subject to the deadlines and other requirements described under “Stockholder Proposals and Nominations” on page 101 of this proxy statement.

Director Orientation and Continuing Education

Our orientation program is structured to acquaint our new directors with our business, strategy, product portfolio, industry and competitive considerations, organizational talent, and capital structure, as well as the legal and ethical responsibilities of our board. Key members of our management team spearhead the program through a series of one-on-one sessions with each new director, with each session concentrated on a specific area of focus. As there are multiple sessions of this nature, we strive to stagger

and prioritize these meetings accordingly, tailored to our directors’ profiles and committee assignments, among other things.

Our program is time intensive but we believe the program is instrumental in driving board performance. In addition to our orientation program, we encourage continuing education for our directors, including through external opportunities, and we assist in finding appropriate courses and fully reimbursing for such programs.

Director Overboarding Policy and Time Commitments

Our overboarding policy, which is reviewed on an annual basis, states that subject to such exceptions on a case by case basis as the board shall determine, no non-executive director can serve on more than 4 public boards (including ADP) and, in the case of a director who is an executive officer of ADP or other company, no more than 2 public boards (including ADP). Our corporate governance principles further state that directors should plan to make a significant time commitment to the company and that

the board’s assessment of individuals for new or continued service on the board includes this consideration, among other things.

The board understands the importance of evaluating the contributions of each of its members and will continue to engage in an in-depth review of each member’s contributions on at least an annual basis before their renomination to the board.

The Board’s Role in Risk Oversight

Our board of directors provides oversight with respect to the company’s enterprise risk assessment and risk management activities, which are designed to identify, prioritize, assess, monitor and mitigate the various risks confronting the company, including risks that are related to the achievement of the company’s operational and financial strategy. As set forth in more detail below, the board of directors performs this oversight function periodically as part of its meetings and also through its audit, compensation and management development, corporate development and technology and nominating/corporate governance committees, each of which examines various components of risk as part of its assigned responsibilities.

Our nominating/corporate governance committee oversees enterprise risk management and is responsible for recommending to our board an allocation of risk oversight responsibilities among the board and its committees.

Our committees report back on risk oversight matters directly to the board of directors on a regular basis. Management is responsible for implementing and supervising day-to-day risk management processes and reporting to the board of directors and its committees as necessary.

Audit Committee

Our audit committee focuses on financial risks, including reviewing with management, our internal auditors, and our independent auditors, the company’s major financial risk exposures, the adequacy and effectiveness of accounting and financial controls, and the steps management has taken to monitor and control financial risk exposures.

In addition, our audit committee reviews risks related to compliance with applicable laws, regulations, and ethical standards. Our audit committee regularly receives, reviews and discusses with management presentations and analyses on various risks confronting the company.

Oversight of Cybersecurity
Our board of directors recognizes that security is integral to our products, our business processes and infrastructure. We have an enterprise-wide approach to security with the objectives of protecting client data and funds, and preventing security incidents that could adversely affect the confidentiality, integrity, or availability of our information systems and data that resides in those systems, while also improving our system resilience with the aim of minimizing the impact to our business when incidents do occur. Our global security organization is tasked with monitoring physical and cybersecurity risks, including operational risks related to information security and system disruption. A cross-functional, enterprise-wide management program operates to promote our global cybersecurity program’s effectiveness and members of the company’s executive committee, through an executive security council, routinely review strategy, policy, program effectiveness, standards enforcement and cyber issue management. Our board of directors is actively engaged in the oversight of our global cybersecurity program. More information on our program is available on our corporate website, at www.adp.com. To access this information, click on “About” then “Data Security.”

✓ | Our board of directors receives regular, quarterly reports on these matters from our chief security officer and leadership from our global product and technology organization, including on the status of projects to strengthen the company’s security systems and improve cyber readiness, as well as on existing and emerging threat landscapes.
✓ | In addition, our corporate development & technology committee receives regular, quarterly reports on our global product security and resiliency program led by leadership from our global product and technology organization with assistance from our chief security officer.
✓ | Concurrent and in addition to these reports, our chief administrative officer (who oversees legal, security and compliance matters) provides a legal, regulatory and ethics update at each meeting of the audit committee, which includes matters of cybersecurity, as appropriate. In addition, important actual or emerging cybersecurity events are communicated to the board of directors by our chief administrative officer and chief legal officer, even if immaterial to us.

✓ | Given the importance of cybersecurity to our stakeholders, our global cybersecurity program is subject to an annual third-party assessment overseen by our board of directors and this assessment reviews all aspects of our cyber program. |  | ✓ | Members of our board receive a read-out of our annual cybersecurity table-top exercise for senior management to validate, test and assess the effectiveness and adequacy of certain roles and decision-making processes in the event of an incident.
✓ | Findings are reported to our board and in response, ADP develops initiatives to improve our maturity across each of the pillars of the National Institute of Standards and Technology Cybersecurity Framework. |  |
✓ | The status of these initiatives is then reviewed with our board during its quarterly meetings. This governance process encourages an environment of continuous improvement. |  |  |
✓ | In advance of these quarterly meetings, members of our board with cybersecurity expertise may informally meet with our chief administrative officer, chief security officer and other members of leadership, as appropriate, to advise and provide additional guidance and industry insights to the company. |  |  |

Oversight of Privacy
Intertwined with our global cybersecurity program is our global privacy program. Our audit committee oversees matters of privacy and receives reports on these matters at each meeting from our chief administrative officer, as well as regular updates from our head of global compliance, including on related risk assessment and risk management activities. On a management level, ADP’s privacy program is led by ADP’s global chief privacy officer and the members of the global data privacy and governance team, in cooperation with the privacy stewards of all of ADP’s business units and functional areas. Our global chief privacy officer provides regular reports to our company’s executive committee, and our audit committee is actively engaged in the oversight of our global privacy program. Our global data privacy and governance team, in cooperation with the chief data office, also is responsible for our artificial intelligence (“AI”) ethics and governance program, which drives compliance with AI ethical principles and regulatory requirements in development and usage of AI systems, including generative AI tools. AI governance is integrated with the reporting discussed above.

✓ | ADP’s Privacy Commitment: We are committed to compliance with privacy requirements and the protection of all personal data processed by ADP. ADP has adopted a set of privacy principles that serve as the foundation for our global privacy program, which includes our global privacy policy and our binding corporate rules (“BCRs”), all of which may be found in greater detail on our corporate website, at www.adp.com. To access this information, click on “About” then “Data Privacy.”
✓ | Our BCRs cover the transfer of data between ADP affiliates across the globe and ensure the highest standard of protection to personal data processed by ADP, regardless of where such data is being processed. Our BCRs establish the rules for processing personal data at ADP as both a data processor (covering the processing of clients’ data in the European Union, Switzerland, South Africa, and through separate documentation, the United Kingdom) and a data controller (covering the data of our employees under a controller workplace code, and other business associates under a business controller code regardless of where such data is being collected). We continue to rank among an elite number of companies worldwide to have gained regulators’ approval to implement BCRs as both a data processor and data controller.
✓ | Our AI Ethics Principles and our AI governance program provide a framework for how we develop and implement the AI-enabled products and services we offer, including those utilizing machine learning and generative AI. Through our compliance-by-design approach, we address human oversight, mitigating bias, privacy-by-design, explainability and transparency, data quality, operational monitoring, a culture of responsible AI, and inclusion and training.
| ✓ | ADP also has an AI & Data Ethics Council, established since 2019, composed of industry leaders and ADP experts who meet regularly to provide guidance within ADP on the responsible use of AI and machine learning and evaluate novel uses of data for compliance with both ADP’s AI Ethics Principles and governing laws.

Compensation and Management Development Committee

Our compensation and management development committee oversees risks related to compensation policies and practices, including management succession planning and our talent strategy, including the recruitment, development and retention of executive talent.

Compensation and Risk Management
Our compensation and management development committee considered the risks presented by the company’s compensation policies and practices at its meetings in August 2024 and 2025 and believes that our policies and practices of compensating employees do not encourage excessive or unnecessary risk-taking for the following reasons:

✓ | Diverse Performance Measures. Our incentive plans have diverse performance measures, including company and business unit financial measures, key client satisfaction, transformation, paperless and HCM objectives, and individual goals. |  | ✓ | Balance. Our compensation programs balance annual and long-term incentive opportunities, cash and equity, and fixed and variable incentives.

✓ | Payout Caps. We cap incentive plan payouts within a reasonable range. |  | ✓ | Mix. The mix of performance-based equity awards and RSUs in our long-term incentive programs serves the best interests of stockholders and the company. |  | ✓ | Stock Ownership Guidelines. Our stock ownership guidelines link the interests of our executive officers to those of our stockholders.

✓ | Clawback Policy. We maintain a rigorous Clawback Policy which exceeds Nasdaq listing requirements and allows for the recovery of both cash and equity incentive compensation from any current or former corporate officer (including any executive officer) who engages in any activity that is in conflict with or adverse to the company’s interests, including fraud. |  | ✓ | Other. We prohibit our directors and all of our employees from engaging in any hedging or similar transactions involving ADP securities, holding ADP securities in a margin account, or pledging ADP securities as collateral for a loan. Transactions in ADP securities by our executive officers are executed through a 10b5-1 program.

The Board’s Role in Human Capital Management and Talent Development

As part of its focus on human capital management and tight integration with company strategy, a key responsibility of our board of directors is to ensure that ADP has a strong, performance-driven senior management team in place. In connection with this responsibility, our board of directors oversees the development and retention of senior talent to ensure that an appropriate succession plan is in place for our CEO as well as the members of the company’s executive committee that directly support our CEO.

Our compensation and management development committee regularly reviews the bench strength of our senior management talent, including readiness to take on additional leadership roles and developmental opportunities needed to prepare senior leaders for greater responsibilities.

As part of building an inclusive workforce to support a culture of openness and innovation at ADP, our compensation and management development committee also regularly assesses the talent pool of candidates just below the executive committee level to ensure a robust talent pipeline. In parallel, the company shares with other committees of the board, as appropriate, a similar view

of the talent pipeline of various functions and businesses within the company. For example, the company annually shares with the CDTC our talent acquisition strategy, evolving skill mix, composition and talent pipeline of the company’s global product and technology organization.

While our compensation and management development committee has the primary responsibility to develop succession plans for the CEO position, it regularly reports to the board of directors and decisions are made at the board level. In connection with this responsibility for developing managerial succession plans, our board of directors reviews, at least annually, the short, medium and long-term succession plans for the company’s senior management, including the CEO.

This annual review also includes a review of the company’s broader HCM practices. In addition, our board meets regularly with high-potential executives from ADP’s various business units at each regular board meeting, which provides our board with greater, direct exposure to a broader group of pipeline candidates.

Corporate Social Responsibility at ADP

At ADP, innovation is the heart of our business — and the values that led us to become a global leader in HR and payroll solutions still guide our way after 75 years. As we focus on solving complex business challenges for our clients and their workers — we are keenly aware of our

responsibility to contribute to progress in business and beyond. We are in the fortunate position to support more than 1.1 million clients and their workers. And, with every interaction, we have an opportunity to make a meaningful impact and help build a better future.

Communications to the board of directors, the non-management directors, or to any individual director that relate to the company’s accounting, internal accounting controls, or auditing matters are referred to the chair of the audit committee.

Transactions with Related Persons

We have a written “Related Persons Transaction Policy” pursuant to which any transaction between the company and a “related person” in which such related person has a direct or indirect material interest, and where the amount involved exceeds $120,000, must be submitted to our nominating/corporate governance committee for review, approval, or ratification.

A “related person” means a director, executive officer or beneficial holder of more than 5% of the company’s outstanding common stock, or any immediate family member of the foregoing, as well as any entity at which any such person is employed, is a partner or principal (or holds a similar position), or is a beneficial owner of a 10% or greater direct or indirect equity interest in that entity. Our

directors and executive officers must inform our general counsel at the earliest practicable time of any plan to engage in a potential related person transaction.

This policy requires our nominating/corporate governance committee to be provided with full information concerning the proposed transaction, including the benefits to the company and the related person, any alternative means by which to obtain like benefits, and terms that would prevail in a similar transaction with an unaffiliated third party. In considering whether to approve any such transaction, the nominating/corporate governance committee will consider all relevant factors, including the nature of the interest of the related person in the transaction and whether the transaction may involve a conflict of interest.

President, Smart Compliance Solutions & Human Resources Outsourcing, is employed as an associate at the company and received total cash compensation for fiscal year 2025 in excess of $120,000.

Insider Trading Policy

Our company maintains an insider trading policy to provide guidelines to all directors, officers, associates and consultants of ADP with respect to trading in ADP securities, as well as the securities of publicly traded companies with whom ADP has a business relationship. The policy prohibits trading by any person while in possession of material non-public information in violation of applicable law and provides for restricted periods and pre-clearance procedures for our directors and officers and certain other specified persons, as well as other related policies and procedures.

Our insider trading policy prohibits all of our directors and employees, including our executive officers, from engaging in any hedging or similar transactions involving ADP securities. The policy also prohibits all of our directors and employees, including our executive officers, from holding ADP securities in a margin account or pledging ADP securities as collateral for a loan. We believe that the insider trading policy is reasonably designed to promote compliance with insider trading laws, rules and regulations and listing standards applicable to ADP.

Compensation of Non-Employee Directors

Our nominating/corporate governance committee reviews and evaluates non-employee director compensation on an annual basis to ensure that (i) our directors are compensated appropriately for their substantial time commitment and responsibilities, (ii) the structure and design of the compensation program enables us to attract and retain highly qualified directors who can bring the depth of knowledge, skills and experience required to govern a company of our scale and complexity, and (iii) it is transparent and fosters commonality of interests between board members and our stockholders.

The nominating/corporate governance committee makes recommendations to the board of directors, as appropriate, based on its review, benchmark information from peer companies (which is the same comparator group used for executive compensation benchmarking purposes), input from its external advisor FW Cook, and other relevant considerations. The elements of our non-employee director compensation program are as follows:

Compensation Element | Fiscal Year 2025 Compensation
Director Annual Retainer | ●$230,000 Deferred Stock Units (“DSUs”) ●$130,000 Cash or DSUs
Additional Non-Executive Chair Retainer | ●$100,000 DSUs ●$100,000 Cash or DSUs
Committee Chair Retainers (Cash, Deferred or DSUs) | ●Audit: $25,000 ●Compensation and Management Development: $20,000 ●Nominating/Corporate Governance: $15,000 ●Corporate Development and Technology: $15,000

Annual Retainers

The annual retainer for non-employee directors is $360,000, $230,000 of which is paid in the form of DSUs and $130,000 of which may, at the election of each director, be paid in cash or in DSUs.

In addition, the chair of our board of directors receives an incremental retainer of $200,000, $100,000 of which is paid in the form of DSUs and $100,000 of which may, at the election of the chair, be paid in cash or in DSUs. This incremental retainer resulted in a total annual retainer of $560,000 for the board leadership role and Mr. Lynch received $560,000 at the time of the 2024 Annual Meeting of Stockholders.

The chair of the audit committee was paid an additional annual retainer of $25,000, the chair of the compensation and management development committee was paid an additional annual retainer of $20,000, and each of the chairs of the nominating/corporate governance committee and corporate development and technology committee was paid an additional annual retainer of $15,000. The additional annual retainer may, at the election of each committee chair, be paid in cash, deferred or paid in DSUs.

Deferral Policy

Pursuant to our amended and restated 2018 Omnibus Award Plan (and previously, under our prior amended and restated 2008 Omnibus Award Plan), each non-employee director is credited with an annual grant of DSUs on the date established by the board for the payment of the annual retainer equal in number to the quotient of the non-elective portion of the retainer ($230,000 for fiscal year 2025 and $330,000 in the case of Mr. Lynch), divided by the closing price of a share of our common stock on the date this amount is credited. The elective portion of the annual retainer is credited in the same manner for directors who elect DSUs. DSUs are fully vested when credited to a director’s account. When a dividend is paid on our common stock, each director’s account is credited with an amount equal to the cash dividend. When a director ceases to serve on our board, such director will receive a number of shares of common stock equal to the number of DSUs in such director’s account and a cash payment equal to the dividend payments accrued, plus interest on the dividend equivalents from the date such dividend equivalents were credited. The interest will be paid with respect to each twelve-month period beginning on November 1 of such

period to the date of payment and will be equal to the rate for five-year U.S. Treasury Notes published in The Wall Street Journal® on the first business day of November of each such twelve-month period plus 0.50%. Non-employee directors do not have any voting rights with respect to their DSUs. Other than Ms. Haynesworth, all of our non-employee directors chose to receive the entire elective portion of their annual retainers in the form of DSUs during fiscal year 2025.

Role of the Nominating/Corporate Governance Committee

The nominating/corporate governance committee is responsible for reviewing, evaluating, and making recommendations to the board on an annual basis with respect to all aspects of non-employee director compensation. The full board then reviews these recommendations and makes a final determination on the compensation of our non-employee directors. During fiscal year 2025, the nominating/corporate governance committee engaged FW Cook, compensation consultant to the compensation and management development committee, to review the design and competitiveness of our non-employee director compensation program.

Changes to Director Compensation in Fiscal Year 2026

In connection with the annual review discussed above, the board of directors approved (i) an increase to the non-elective portion of the annual retainer to $240,000 (from $230,000), which will be paid in the form of DSUs, and (ii) an increase to the chair retainers of the nominating/corporate governance committee and corporate development and technology committee to $17,500 (from $15,000), each to be effective at the time of the 2025 Annual Meeting of Stockholders. There were no other changes made to the non-employee director compensation program for fiscal year 2026.

Stock Ownership Guidelines

Our stock ownership guidelines are intended to promote ownership in the company’s stock by our non-employee directors and to align their financial interests more closely with those of other stockholders of the company. Each non-employee director has a minimum stockholding requirement of our common stock equal to five times his or her annual cash retainer.

| Proposal 2 Advisory Vote on Executive Compensation

We are asking stockholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the company’s named executive officers as disclosed in the Compensation Discussion and Analysis, the accompanying compensation tables and the related narrative disclosure in the company’s proxy statement for the 2025 Annual Meeting of Stockholders.

The board of directors recommends a vote FOR this resolution because it believes that the policies and practices described in the Compensation Discussion and Analysis are effective in achieving the company’s goals of linking pay to executive performance and levels of responsibility,

encouraging our executive officers to remain focused on both short-term and long-term financial, client satisfaction, transformation, paperless and HCM goals of the company, and aligning the interests of our executive officers with the interests of our stockholders by linking executive performance to stockholder value.

We urge stockholders to read the Compensation Discussion and Analysis section appearing on pages 40 through 62 of this proxy statement, as well as the “Summary Compensation Table For Fiscal Year 2025” and related compensation tables and narrative appearing on pages 64 through 91 of this proxy statement, which provide detailed information on the company’s compensation policies and practices and the compensation of our named executive officers.

Stockholder Approval Required

The affirmative vote of the holders of a majority of the shares represented in person or by proxy and entitled to vote thereon is required to approve the advisory resolution on executive compensation. Properly executed proxies will be voted as marked. Executed but unmarked proxies will be voted in favor of the advisory resolution on executive compensation. Because the vote on this proposal is advisory in nature, it will not affect any compensation already paid or awarded to any named executive officer and will not be binding on or overrule any decisions by the compensation and management development committee or the board of directors.

Because we value our stockholders’ views, however, the compensation and management development committee and the board of directors will consider carefully the results of this advisory vote when formulating future executive compensation policy.

Compensation Discussion and Analysis

The following Compensation Discussion and Analysis, or “CD&A,” section of this proxy statement discusses the material elements of our fiscal year 2025 executive compensation programs for the following persons, who are our named executive officers, or “NEOs:”

Name |  | Title
Maria Black |  | President and Chief Executive Officer
Don McGuire |  | Corporate Officer and Former Chief Financial Officer
Michael A. Bonarti |  | Chief Administrative Officer
Joseph DeSilva |  | Executive Vice President (“EVP”), North America and Chief of Operations
Sreeni Kutam |  | President, Global Product & Innovation
John C. Ayala |  | Former Chief Operating Officer

Effective June 30, 2025, Mr. McGuire stepped down from his role as Chief Financial Officer and continues to serve as a corporate officer of the company during a transition period through September 30, 2025. Mr. Ayala’s last day of employment with the company was March 31, 2025.

The CD&A also provides an overview of our executive compensation philosophy and explains how the compensation and management development committee of our board of directors (the “committee”) arrives at specific compensation decisions involving the NEOs.

In addition, the CD&A explains how our executive compensation programs are designed and operate with respect to our NEOs by discussing the following fundamental aspects of our compensation programs:

✓ | compensation principles |  | ✓ | cash compensation |  | ✓ | long-term incentive compensation |  | ✓ | other compensation components and considerations (including retirement benefits and deferred compensation)

Executive Summary

Stockholder Support for our Compensation Programs

The committee continuously evaluates the degree to which our compensation programs link pay to performance and support the evolution of objectives that underpin our strategy and the related implication for human capital planning. In particular, the committee takes steps to ensure that the programs encourage our executive officers to remain focused on both the short-term and long-term financial, client satisfaction, transformation, paperless and human capital management (“HCM”) goals of the company and that the metrics included in both our annual and longterm incentive compensation plans complement each other to create a balanced focus on year-over-year improvement and sustainable long-term value creation. Each year the committee sets rigorous and challenging performance targets aligned to these company goals. We continue to believe that growth in revenue (including and excluding zero-margin benefits pass-throughs), new business bookings, adjusted earnings before interest and taxes (“EBIT”) and adjusted net income (each as defined on pages 43 and 44), are the most important measures of the successful execution

of our objectives and the delivery of sustainable long-term stockholder value. We also believe that our client satisfaction, transformation, paperless and HCM objectives are important leading indicators of the company’s progress, long-term value, and future success, and reflect our commitment to delivering a more human, simple and sustainable business process for all of those we serve.

At our 2024 Annual Meeting of Stockholders, our stockholders approved the compensation of our fiscal year 2024 NEOs by a vote of approximately 90%, reflecting a strong support level generally in line with the 2023 result of 91%. Our committee, with input from the independent compensation consultant, considered the vote results, stockholder feedback (as discussed on page xiv) and other facts and data referenced in this CD&A to retain the basic foundation of our overall compensation program during fiscal year 2025 as the committee believes the program continues to support and drive the right management behavior, retain key talent and align to the interests of our stockholders.

This top-line revenue growth, balanced with solid margin performance, drove earnings per share (“EPS”) growth of 10%. Other key business drivers such as

new business bookings and client satisfaction (net promoter scores) also reached new record levels and our overall results, together with our focus on sound capital allocation, have served to further strengthen our business model with high levels of recurring revenue, strong operating cash flow, and a solid balance sheet.

Our capital deployment priorities remain unchanged – leverage the strength of our model to reinforce our competitive position by, first and foremost, reinvesting in the business. We believe that balancing investments in innovative solutions, client service tools, and distribution is critical to strengthening our market-leading offerings. We supplement these investments through a disciplined approach to M&A. Our focus on delivering top-line revenue growth, while also improving the efficiency and

From HR, payroll, time and benefits to HR outsourcing, talent, compliance and retirement, our solutions span the entire employee experience from hire to retire. As we look ahead to fiscal year 2026 and beyond, we are focused on delivering healthy returns to our stockholders through strong revenue growth and margin expansion and we will continue to focus on people, as we leverage our unparalleled data insights and innovative technology to build a world of work that is smarter, easier, and more human.

2025 Incentive Compensation Performance Metrics

Our financial performance impacted the compensation of our executive officers in several ways, most notably through our annual cash bonus plan and performance-based stock unit (“PSU”) program.

Performance for all metrics, including the client satisfaction, transformation, paperless and HCM objectives under the annual cash bonus plan, are formulaically measured, based on predetermined and objectively quantifiable goals. Targets and results for our financial metrics exclude the impact of certain limited items pursuant to predetermined categories of adjustments established by the committee at the time that targets were set.

Annual Cash Bonus Plan. The committee’s determination of incentive compensation under our annual cash bonus plan for our executive officers, including our NEOs, was based on fiscal year 2025 revenue growth, new business bookings growth, and adjusted EBIT growth as well as client satisfaction, transformation, paperless and HCM objectives.

These fiscal year 2025 goals were established consistent with the committee’s long-standing methodology in setting such goals and as such, align to the financial earnings guidance the company communicated in July 2024 for fiscal year 2025 and reflect ADP’s expectations and assumptions at that time.

Details with regard to non-financial objectives are provided on page 55 and the financial goals and performance results are summarized below. Each bonus measure below is expressed as a percentage-based growth goal, thus requiring correspondingly higher levels of absolute year-over-year performance delivery. For fiscal year 2025, our NEOs received cash bonuses at 107.1% of target.

Annual Cash Bonus Plan Measures |  | Plan Targets |  | Plan Results
Revenue Growth |  |  | 5.7% |  |  | 7.1%, excluding the impact of foreign currency fluctuations in excess of the fluctuations assumed in the target
New Business Bookings Growth(1) |  |  | 7.8% |  |  | 3.5%
Adjusted EBIT Growth(2) |  |  | 8.8% |  |  | 9.7%, excluding the impact of foreign currency fluctuations in excess of the fluctuations assumed in the target

1 | For fiscal year 2025, our new business bookings definition includes annualized recurring revenues anticipated from sales orders to new and existing clients for Employer Services and Professional Employer Organization (“PEO”) Services. It excludes revenue that is one-time in nature and zero-margin benefits pass-throughs.
2 | Our adjusted EBIT measure excludes the impact of taxes, certain interest expense, certain interest income, and certain other items. We continue to 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. Refer to the table in Appendix A for a reconciliation from net earnings to adjusted EBIT for fiscal years 2025 and 2024.

Long-Term Incentive Program. Performance incentive compensation under our PSU program was based on the achievement of adjusted net income growth (67% weight) and revenue excluding zero-margin benefits pass-throughs (“revenue ex-ZMPT”) growth (33% weight) for fiscal year 2025. PSU awards are also subject to a relative total shareholder return (“rTSR”) metric that may modify the final payout (by +/-20%) at the end of the respective full three-year period based on our performance as compared to the S&P 500. Targets and results exclude the impact of certain limited items pursuant to predetermined categories of adjustments established by the committee at the

time the targets were set. For more information on the application of these performance metrics, see “Long-Term Incentive Compensation Programs” in this CD&A.

These financial goals for the PSU awards granted in fiscal year 2025 were established consistent with the committee’s long-standing methodology in setting such goals and as such, align to the financial earnings guidance the company communicated in July 2024 for fiscal year 2025 and reflect ADP’s expectations and assumptions at that time. Each PSU measure below is expressed as a percentage-based growth goal, thus requiring correspondingly higher levels of absolute year-over-year performance delivery.

PSU Program Measures |  | Program Targets |  | Program Results
Adjusted Net Income Growth(1) |  |  | 7.9% |  |  | 10.6%, excluding the impacts of: ● Foreign currency fluctuations in excess of the fluctuations assumed in the target ● First-year impact of business acquisitions
Revenue ex-ZMPT Growth(2) |  |  | 5.6% |  |  | 6.2%, excluding the impacts of: ● Foreign currency fluctuations in excess of the fluctuations assumed in the target ● First-year impact of business acquisitions

1 | Our adjusted net income measure excludes the impact of certain one-time charges and benefits reflecting specific items that are not fundamental to our underlying business operations. Refer to the table in Appendix A for further detail on these items and a reconciliation from net earnings to adjusted net income for fiscal years 2025 and 2024.
2 | Our revenue ex-ZMPT measure is a consolidated revenue growth measure that excludes the impact of zero-margin benefits pass-throughs. Importantly, the PSU revenue metric is not duplicative of the annual cash bonus plan revenue metric due to the exclusion of zero-margin benefits pass-throughs. Refer to the table in Appendix A for further detail on this item and a reconciliation from consolidated revenue to revenue ex-ZMPT for fiscal years 2025 and 2024.

A payout percentage of 132% was achieved under our PSU program as a result of our fiscal year 2025 adjusted net income growth and revenue ex-ZMPT growth. The payout percentage of 132% applies to year 1 of the fiscal year 2025 award, year 2 of the fiscal year 2024 award, and year 3 of the fiscal year 2023 award. In addition, the three-year rTSR performance period for the fiscal year 2023 PSU

award concluded at the end of fiscal year 2025, with a final modifier performance achievement of +114.5% based on our TSR percentile rank of 68.1 relative to the S&P 500 (the fiscal year 2025 and 2024 awards remain subject to final adjustment based on rTSR performance over the respective three-year performance periods).

As described in the table below, the financial metric payout percentages achieved for each of the individual three fiscal years in the applicable performance period are averaged to obtain the award level earned as a percentage of target. The three-year financial metric average is then subject to

adjustment based on achievement of the three-year rTSR modifier, in order to determine the final award payout percentage of target. Based on this methodology, the fiscal year 2023 PSU award granted in September 2022 achieved a final payout of 137%, as summarized below.

Elements of Compensation

The committee determines the compensation of our chief executive officer and all other executive officers. When making decisions related to officers, including the NEOs (other than our chief executive officer), the committee considers recommendations from the chief executive officer as well as guidance from its independent compensation consultant. When making decisions related to our chief executive officer, the committee considers guidance from its independent compensation consultant. The following table summarizes the major elements of our fiscal year 2025 executive officer compensation programs.

Compensation Element |  | Objectives |  | Key Characteristics
Base Salary |  | To provide a fixed amount for performing the duties and responsibilities of the position |  | Determined based on overall performance, level of responsibility, competitive compensation data and comparison to other company executives
Annual Cash Bonus |  | To motivate executive officers to achieve key financial and non-financial performance goals |  | Payment based on achievement of company-wide, business unit, client satisfaction, transformation, paperless and HCM performance goals
Performance-Based Stock Unit (“PSU”) Awards |  | To motivate executive officers to achieve certain longer-term goals and create long-term alignment with stockholders |  | Awards based on target growth in adjusted net income and revenue ex-ZMPT, with earned shares issued following applicable performance period, subject to a relative TSR modifier
Time-Based Restricted Stock Unit (“RSU”) Awards |  | To attract and retain executive officers |  | Granted annually and vesting ratably over three years. May also be awarded on a limited, non-recurring basis to attract and recruit new talent and for long-term retention of critical executives, as well as part of management succession planning

The graphs that follow illustrate the alignment between company performance and the incentive compensation paid to Ms. Black, our chief executive officer, for fiscal year 2025. In the case of PSUs, the table reflects a payout of 137% based on the average of the financial metric annual achievement percentages of 117%, 111%, and 132% (as a result of adjusted net income growth and revenue ex-ZMPT growth) for the three-year performance period comprised of fiscal years 2023, 2024 and 2025, respectively, and application of the three-year rTSR modifier achievement of +114.5%.

Good Governance and Best Practices

We are committed to ensuring that our compensation programs reflect principles of good governance.

What we do

✓ | Pay for performance: We design our compensation programs to link pay to performance and levels of responsibility, to encourage our executive officers to remain focused on both the short-term and long-term financial, client satisfaction, transformation, paperless and HCM goals of the company and to link executive performance to stockholder value.
✓ | Annual say-on-pay vote: We hold an advisory say-on-pay vote to approve our NEO compensation on an annual basis.
✓ | Clawback policy: We maintain a rigorous Clawback Policy which exceeds Nasdaq listing requirements and allows for the recovery of both cash and equity incentive compensation from any current or former corporate officer (including any executive officer) who engages in any activity that is in conflict with or adverse to ADP’s interests, including fraud.
✓ | Stock ownership guidelines: We maintain stock ownership guidelines to encourage equity ownership by our executive officers. The stock ownership guideline for Ms. Black is six times base salary. The other NEOs have a stock ownership guideline of three times base salary. Executive officers whose ownership levels are below target ownership levels are required to retain as shares of common stock at least 75% of post-tax net gains on stock option exercises, and 75% of shares (net of taxes) received upon vesting of RSUs or received under our PSU program.
✓ | Limited perquisites: We provide limited perquisites that are viewed as consistent with our overall compensation philosophy.

✓ | Double trigger change in control payments: Our Change in Control Severance Plan for Corporate Officers includes “double-trigger” provisions, such that payments of cash and vesting of equity awards occur only if termination of employment without cause or with good reason occurs during the two-year period after a change in control.
✓ | Independence of our compensation and management development committee and advisor: The compensation and management development committee of our board of directors, which is comprised solely of independent directors, utilizes the services of FW Cook as an independent compensation consultant. FW Cook reports to the committee, does not perform any other services for the company other than in connection with an annual review of competitive director compensation for the nominating/corporate governance committee of our board of directors, and has no economic or other ties to the company or the management team that could compromise their independence and objectivity.
✓ | Equity plan best practices: Our 2018 Omnibus Award Plan, approved by stockholders in November 2018, incorporates certain governance best practices, including a minimum vesting period of one-year (with certain limited exceptions), a minimum 100% fair market value exercise price (except for substitute awards from an acquired or merged company), no “liberal share recycling” of stock options or stock appreciation rights and no “liberal” change in control definition.
✓ | Stockholder engagement: As described under “Fiscal Year 2025 Stockholder Engagement” on page xiv of this proxy statement, our investor engagement program promotes an active dialogue with our largest stockholders on a range of topics related to our strategy, corporate governance and executive compensation programs.

What we don’t do

✗ | No-hedging policy: We prohibit all of our directors and employees, including our executive officers, from engaging in any hedging or similar transactions involving ADP securities.
✗ | No-pledging policy: We prohibit all of our directors and employees, including our executive officers, from holding ADP securities in a margin account or pledging ADP securities as collateral for a loan.
✗ | No repricing of underwater stock options without stockholder approval: We may not lower the exercise price of any outstanding stock options or otherwise provide economic value to the holders of underwater stock options in exchange for the forfeiture of such awards without stockholder approval.

✗ | No discount stock options: The exercise price of our stock options is not less than 100% of the fair market value of our common stock on the date of grant.
✗ | No IRC Section 280G or 409A tax gross-ups: We do not provide tax gross-ups under our change in control provisions or deferred compensation programs.
✗ | No current dividends on unearned PSUs: We do not pay dividends in respect of unearned PSUs; rather, dividend equivalents are accrued over the applicable performance period and are paid only if the units are earned and shares are issued at the end of the performance period.

Looking Forward

For fiscal year 2026, we implemented a change to the annual cash bonus plan to increase the weight of the client retention measure, as we believe it is fundamental to our business and directly tied to our recurring revenue model. More information will be provided in our proxy statement for fiscal year 2026. For more information on the bonus plan and measurements used for fiscal year 2025, see “Annual Cash Bonus” and “NEOs’ Fiscal Year 2025 Bonuses” in this CD&A.

Compensation Discussion and Analysis

Compensation Principles

We believe that compensation should be designed to create a direct link between performance and stockholder value. Five principles that guide our decisions involving executive compensation are that compensation should be:

1 | based on (i) the overall performance of the company, (ii) the performance of each executive’s business unit when applicable and (iii) each executive’s individual performance
2 | closely aligned with the short-term and long-term financial, client satisfaction, transformation, paperless and HCM objectives that build sustainable long-term stockholder value
3 | competitive, in order to attract and retain executives critical to our long-term success
4 | consistent with high standards of corporate governance and best practices
5 | designed to dampen the incentive for executives to take excessive risks or to behave in ways that are inconsistent with the company’s strategic planning processes and high ethical standards

Our compensation programs are designed so that target pay reflects relative levels of responsibility among our key executives, and such that the proportion of pay tied to operating performance and changes in stockholder value varies directly with the level of responsibility and accountability to stockholders. We assign all executives to pay grades by comparing their position-specific duties and responsibilities with market data and our internal management structure. Each pay grade has ranges for base salaries, total annual cash compensation and annual equity grants based on market competitive levels. Executives are positioned within these ranges based on a variety of factors, most notably their experience and skill set and their performance over time.

We design our performance-based compensation so that actual, realized compensation will vary relative to the target award opportunity based on performance. As such, actual compensation amounts may be above or below targeted levels depending on the overall performance of the company, performance of a business unit and achievement of performance goals that support our strategy. We have adopted this compensation design to provide meaningful incentives for our key executives to achieve desired results. We also believe that it is important for our executive officers to have an ongoing long-term investment in the company as outlined on page 62 of this proxy statement under “Stock Ownership Guidelines.”

We have a clear strategy to maximize sustainable long-term stockholder value that includes balancing growth, profitability and risk, with clear financial goals that allow us to continue to innovate technologically and expand globally. Each year the committee sets rigorous and challenging performance measures aligned to these objectives. We continue to believe that growth in revenue (including and excluding ZMPT), new business bookings, adjusted EBIT and adjusted net income are the most important measures of the successful execution of our objectives and the delivery of sustainable long-term stockholder value.

In fiscal year 2025, we continued to engage with our investor community, including hosting an Investor Day to discuss the company’s strategic priorities. We contacted stockholders representing nearly half our shares outstanding and we discussed our strategy, corporate governance and executive compensation programs with stockholders representing over 20% of our shares outstanding.

To date, the feedback from these engagements have been very positive. While we do receive certain institution-specific observations of pay practices from time to time, we observed that these investors are broadly supportive of the linkage of our performance measures to our executive compensation programs. As described under “Fiscal Year 2025 Stockholder Engagement” on page xiv of this proxy statement, we continue to engage with our stockholders on our executive compensation programs and we look forward to maintaining this ongoing dialogue as well as incorporating feedback into our plans as appropriate.

Compensation Discussion and Analysis

Growth in revenue, adjusted EBIT and new business bookings are important performance measures in annual cash bonus determinations, and adjusted net income and revenue ex-ZMPT are used to determine the number of shares earned in a performance period under our PSU program, which is also subject to a relative total shareholder return (“rTSR”) modifier. All of these performance criteria were chosen for the variable incentive plans because they focus our executive officers on the company’s long-term goals of increasing the growth and profitability of our business, which are the key drivers of sustainable increases in stockholder value.

Consistent with our pay-for-performance philosophy, our NEOs’ compensation is structured with a significant portion of their total compensation at risk. This at-risk compensation includes long-term incentive awards, which

are paid based on the performance of the company as a whole, and annual cash bonuses, which are paid on the basis of the bonus objectives established by the committee as described below under “Fiscal Year 2025 Target Bonus Objectives.”

The mix of target total direct compensation (base salary, cash bonus and long-term incentive awards) for fiscal year 2025 was designed to deliver the following approximate proportions of total compensation to Ms. Black, our chief executive officer, and the other NEOs if company and individual target levels of performance are achieved. The target pay mix below reflects the PSU target award based on the three-year target opportunity. Ms. Black’s higher proportion of at-risk compensation reflects her greater responsibility for overall company performance.

Compensation Consultant

The committee has engaged FW Cook to provide assistance with the design of our compensation programs, the development of comparative market-based compensation data, and the determination of target compensation awards for the chief executive officer. The specific matters on which FW Cook provided advice in fiscal year 2025 were the market trends and regulatory developments in executive compensation and the design of executive compensation programs and practices, including the changes to the pay levels of the chief executive officer, as well as reviewing long-term incentive guidelines for all eligible levels. In June 2024, FW Cook delivered to our committee the results of a competitive assessment of compensation for use in determining fiscal year 2025 target compensation for our chief executive officer Ms. Black. FW Cook also examined the mix of proposed PSU awards and RSU grants for our

NEOs for fiscal year 2025 and confirmed that the proposals for the NEOs were reasonable and appropriate, given the company’s size and structure. In addition, in January 2025, FW Cook reviewed the company’s executive compensation peer group and recommended no changes to the peer group for fiscal year 2026.

As part of its ongoing support to the committee, FW Cook also reviews executive compensation disclosures (including this CD&A), reviews and provides comments on changes to the committee’s charter, advises on emerging trends and the implications of regulatory and governance developments, and reviews and provides commentary on materials and proposals prepared by management that are presented at the committee’s meetings. In addition, our nominating/corporate governance committee engaged FW Cook to review the design and competitiveness of our non-employee director compensation program.

Compensation Discussion and Analysis

The committee determined that the work of FW Cook did not raise any conflicts of interest in fiscal year 2025. In making this assessment, the committee considered the independence factors enumerated in Rule 10C-1(b) under the Securities Exchange Act of 1934, as amended, and applicable Nasdaq listing standards, including the level of fees received from the company as a percentage of FW Cook’s total revenue, the policies and procedures employed by FW Cook to prevent conflicts of interest, the fact that FW Cook does not provide any other services to the company (other than the director compensation program review), and whether the individual FW Cook advisors to the committee own any stock of the company or have any business or personal relationships with members of the committee or our executive officers.

Compensation Review and Determination

ADP uses a customized peer group to benchmark our executive officers’ pay levels and our financial performance in connection with pay-for-performance evaluations, as well as our practices concerning equity compensation and other executive compensation programs. The customized peer group was developed with assistance from FW Cook based upon the following criteria: comparable business model, company size, executive talent sources, competition for investor capital, companies considered by our investors to be our peers, and overall reasonableness. In connection with its annual review of the company’s executive compensation peer group in January 2024, the committee determined that the existing 17-company peer group reflected below remained appropriate for fiscal year 2025.

1 | Effective May 18, 2025, Discover Financial Services was acquired by Capital One Financial Corporation.

In benchmarking the total cash and long-term incentive compensation for the NEOs, the committee reviewed the market compensation data from the customized peer group at its June 2024 meeting. The committee considered that, compared with the peer group, the company compares at the 49th and 63rd percentiles, respectively, regarding revenue and market capitalization. Based on the four most recently reported quarters as of April 30, 2024, revenue among companies in the peer group ranged from approximately $9.8 billion to $64.6 billion, and market capitalization ranged from approximately $19.0 billion to $537.5 billion.

The committee also considered third-party survey data (including the Radford McLagan Compensation Database, the Willis Towers Watson® U.S. General Industry Executive Database, and the Equilar Inc.® Top 25 Database) as reference points to understand general industry compensation practices.

The committee examines compensation summaries detailing the amounts and mix of base salary, cash bonus,

and long-term equity incentives for each of our NEOs, which compare the amounts and mix to competitive compensation practices. We generally target base salary, annual cash bonus and long-term equity incentives at the median of competitive compensation levels, but we will set individual executive targets above or below the median when warranted in the judgment of the committee.

The degree to which target compensation for an executive ranges above or below the median competitive rate is primarily based on each executive’s skill set and experience relative to market peers. Executives who are new in their roles and therefore less experienced than market peers are typically positioned lower in the range, whereas executives with more experience in their roles may be positioned higher in the range. At the time fiscal year 2025 compensation decisions were approved by the committee, Ms. Black was a recently promoted CEO and the competitive positioning of her target compensation remained below the median of our customized peer group.

Compensation Discussion and Analysis

Differences in Compensation of Our NEOs

The committee approved the pay mix for our chief executive officer, which is designed to be competitive when measured against the pay packages of other chief executive officers as indicated by the compensation study.

We have found that due to the broad responsibilities and the experience required for the chief executive officer position, compensation for chief executive officers in public companies that are similar in size to ours is significantly higher than compensation for their other NEOs.

When determining the compensation level for each of our executive officers, the committee reviews each individual compensation element based on the previous year’s level, as well as how the proposed level of that individual compensation element for each executive officer would compare to the other executive officers. The aggregate level for each executive officer’s compensation is then compared against the executive’s previous year’s totals and against compensation of other executive officers of the company.

Cash Compensation

Base Salary

Base salaries are a fixed amount paid to each executive for performing his or her normal duties and responsibilities. We determine the amount based on the executive’s overall performance, level of responsibility, competitive compensation practices data, and comparison to other company executives.

Based on these criteria, our NEOs received annual salary increases in fiscal year 2025, as summarized in the table below.

Named Executive Officer (NEO) |  | Fiscal Year-End 2024 Salary |  | Fiscal Year-End 2025 Salary |  | Increase/ Decrease
Ms. Black |  |  | $1,200,000 |  |  |  | $1,224,000 |  |  |  | 2.0% |
Mr. McGuire |  |  | $696,300 |  |  |  | $710,200 |  |  |  | 2.0% |
Mr. Bonarti |  |  | $642,700 |  |  |  | $655,600 |  |  |  | 2.0% |
Mr. DeSilva(1) |  |  | $600,000 |  |  |  | $650,000 |  |  |  | 8.3% |
Mr. Kutam |  |  | $566,500 |  |  |  | $577,800 |  |  |  | 2.0% |
Mr. Ayala(2) |  |  | $749,800 |  |  |  | $764,800 |  |  |  | 2.0% |

1 | Mr. DeSilva received a 2.0% salary increase on July 1, 2024, and a 6.2% salary increase effective January 1, 2025 in connection with his appointment as EVP, North America and Chief of Operations.
2 | For Mr. Ayala, fiscal year-end 2025 salary reflects his base salary as of March 31, 2025, his last day of active employment with the company.

Except as noted above for Mr. DeSilva’s January 1, 2025 increase, salary increases for the NEOs were made effective July 1, 2024, the first day of fiscal year 2025.

Annual Cash Bonus

Overview

We paid our NEOs cash bonuses for fiscal year 2025 based on the attainment of financial, client satisfaction, transformation, paperless and HCM performance goals established at the beginning of the fiscal year. All of the company’s goals are objectively measurable and were established consistent with the committee’s long-standing methodology in setting such goals. These fiscal year 2025 goals align to the financial earnings guidance the company communicated in July 2024 for fiscal year 2025 and reflect ADP’s expectations and assumptions at that time. For each executive officer, we establish a target bonus amount, which is initially expressed as a percentage of projected year-end annual base salary. For fiscal year 2025, these target bonus percentages ranged from 100% to 200% of base salary for the NEOs. We also assign a percentage value to each bonus component of each NEO’s annual cash bonus plan and then determine the target bonus amount linked to each component. We establish these performance ranges to provide our NEOs with a strong incentive to exceed the targets. The maximum bonus payment for our NEOs is 200% of the target bonus level. There is no guaranteed minimum payment level, and no bonus is payable if threshold performance goals are not achieved.

The committee establishes and approves annual target bonus objectives and award opportunities for each of our NEOs. In making these determinations, the committee considers a variety of factors, including market data, each officer’s relative level of responsibility, and the chief executive officer’s recommendations for executives other than herself. Our NEOs participated in the discussions surrounding their bonus objectives so that they could

provide input and understand the expectations of each bonus plan component, but they did not participate in the setting of the target bonus award opportunities nor did they participate in the committee’s voting or deliberations regarding their individual compensation amounts. Each NEO receives a final version of his or her individualized bonus plan after it is approved by the committee. Except in extraordinary circumstances, bonus objectives are not modified during the fiscal year.

The committee reviews the performance of each of our NEOs relative to his or her annual fiscal year bonus plan objectives at its regularly scheduled August meeting, which is the first meeting following the end of our fiscal year. Based on this review, the committee determines and approves the annual cash bonuses for our executive officers.

NEOs’ Fiscal Year 2025 Bonuses

Our fiscal year 2025 annual cash bonus plan measures consisted of (i) revenue growth, weighted at 20%, (ii) new business bookings growth, weighted at 20%, (iii) adjusted EBIT growth, weighted at 20%, (iv) client satisfaction (client retention and net promoter score targets), weighted at 10%, (v) company transformation objectives, weighted at 20%, and (vi) paperless and HCM objectives, weighted at 10%. Fiscal year 2025 target bonuses were the same percentage of base salary as the percentage targets established in fiscal year 2024 for all NEOs other than Mr. DeSilva, whose target bonus percentage increased from 100% to 150% as part of his promotion to the EVP, North America and Chief of Operations role effective January 1, 2025, for a full year blended target bonus percentage of 125%.

Fiscal Year 2025 Target Bonus Objectives

The table that follows indicates the degree to which each target bonus objective for our NEOs was satisfied. The percentage of target bonus paid to each NEO is calculated as a weighted average of the percentages achieved for each individual objective.

The bonus objectives were designed to reward outcomes that are aligned with the key components of our financial and strategic success, the degree to which the NEOs have responsibility for overall company performance or individual business unit results, and to provide a set of common objectives that facilitate collaborative engagement throughout the company.

● Achieve executive human capital goals |  |  | 5% |  |  |  | Progress on developing and growing ADP’s next generation of leaders |  |  |  | 80.6% |

1 | Refer to the table in Appendix A for a reconciliation from net earnings to adjusted EBIT for fiscal years 2025 and 2024.

In setting target financial performance goals, we consider a variety of factors including our short- and long-range strategic plan, the annual budget reviewed by our board, and the guidance provided by management on key elements of financial performance. Achievement levels are, as a percentage of target, 50% for threshold performance, 100% for target performance, 200% for stretch performance, and 0% for below threshold performance. The targets for revenue growth and adjusted EBIT growth reflect an assumed impact of foreign currency fluctuations anticipated at the time the targets were established. For each metric described above, the award level achieved within each range, as a percentage of target, is determined by linear interpolation between the lower and upper bounds.

Client Satisfaction, transformation, paperless and HCM objectives for our NEOs are aligned with our key strategic goals for fiscal year 2025 and are viewed as important leading indicators of our ongoing progress, creation of long-term value and future success.

The targets for each objective are established to be challenging and rigorous and require strong performance for achievement. The targets are measurable, quantifiable goals. There is no subjectivity applied to the calculation of performance against these objectives. The calculation of performance is formulaic to reflect the proportionate level of achievement relative to the target. Targets for certain measures are considered confidential business information, disclosure of which could harm our operating performance or ability to compete.

Compensation Discussion and Analysis

Long-Term Incentive Compensation Programs

We believe that long-term incentive (“LTI”) compensation is a significant factor in attracting and retaining key executives and in aligning their interests directly with the interests of our stockholders. For fiscal year 2025, long-term incentives were awarded in the form of PSUs and RSUs, with a targeted LTI mix of 75% PSUs and 25% RSUs for all our NEOs. The committee selected these awards because they ensure that the overall long-term incentive program is predominately focused on performance-based pay delivery, closely tied to changes in stockholder value and the degree to which critical operating objectives are attained and supports our talent retention objectives.

The committee may also from time to time grant discretionary awards of RSUs to our executive officers. These awards are for special situations to assist us in the recruitment, promotion or retention of executive officers and are not considered in the target allocation of total long-term incentive compensation between annual PSU and RSU awards. In fiscal year 2025, none of the NEOs received a discretionary RSU award.

As part of our annual market analysis of compensation data, we compare our long-term equity incentive grant values with competitive levels. We establish target long-term incentive award values and ranges for each executive level and set the midpoints of such ranges at the market median levels. The committee reviews the target award values annually to ensure that the resulting awards remain generally consistent with our median compensation philosophy.

Prior to the beginning of each fiscal year, we analyze the target PSU and RSU grant levels to confirm that our desired target long-term incentive compensation values are appropriate in the context of the compensation studies referred to under “Compensation Review and Determination” above. When comparing our desired values to these compensation studies, we look at both equity elements in total.

The target long-term incentive mix approved for fiscal year 2025 grants is shown in the following chart:

Compensation Discussion and Analysis

At its June 2024 meeting, the committee approved target awards of PSUs and RSUs for all NEOs for fiscal year 2025, which were granted in September 2024. The PSU awards (based on the three-year target opportunity) will be earned

and issued following the end of the three-year performance period in fiscal year 2027. The PSUs and RSUs granted for fiscal year 2025 are summarized in the table below:

Named Executive Officer (NEO) |  | Target PSU Award |  | RSU Award |  | Total
Ms. Black |  | $12,771,000 |  | $4,257,000 |  | $17,028,000
Mr. McGuire |  | $4,275,000 |  | $1,425,000 |  | $5,700,000
Mr. Bonarti |  | $3,165,000 |  | $1,055,000 |  | $4,220,000
Mr. DeSilva |  | $3,207,000 |  | $1,069,000 |  | $4,276,000
Mr. Kutam |  | $2,883,300 |  | $961,100 |  | $3,844,400
Mr. Ayala |  | $3,472,500 |  | $1,157,500 |  | $4,630,000

PSU Awards

Our PSU program is based on financial objectives that are measured over a three-year performance period consisting of three one-year performance goals. The committee believes that the current PSU program’s combined effect of (i) measuring performance annually over the three-year performance period enables setting rigorous targets that drive accountability for the achievement of core financial metrics that are critical building blocks for sustained business success and (ii) modifying the actual number of PSUs eligible to be earned based on our three-year rTSR performance, provides the most business-focused, stockholder-aligned and holistic assessment of our long-term trajectory and performance. We believe that the three-year PSU program will further the company’s long-term financial goals by tying a substantial portion of the total compensation opportunity to multi-year performance and better promote talent retention by imposing a meaningful total vesting period.

Financial performance metrics for PSU awards are based on (i) adjusted net income as the primary performance metric, weighted 67%, and (ii) revenue ex-ZMPT as the second performance metric, weighted 33%. The combination of the two metrics is intended to promote focus on both the top-line and bottom-line performance of the business. Notably, the PSU revenue metric differs materially from that used in our annual cash bonus plan because it excludes zero-margin benefits pass-throughs and therefore avoids metric duplication.

The PSU performance goals and corresponding target award ranges are typically established and communicated to our executive officers (including the NEOs) in the first

quarter of each respective fiscal year. After the conclusion of each fiscal year, the committee confirms the performance results and determines the award achieved for such fiscal year, as a percentage of target, based on these results by using linear interpolation between the lower and upper bounds of the applicable percentage range. Under the PSU program, after the end of the three-year performance period, the award levels achieved as a percentage of target for each of the individual three fiscal years in the applicable performance period will be averaged to obtain the overall financial metric award level earned as a percentage of target, which may range up to 175%.

The PSU award performance design also includes a three-year rTSR metric that may modify the overall financial metric award level by +/- 20% based on the company’s performance versus the S&P 500; the inclusion of the rTSR metric is intended to provide accountability for the company’s stock price performance over the full three-year performance period. In order to align with the most prevalent peer market practices and encourage executives to achieve stretch goals, the maximum payout opportunity for PSU awards is 200% of target, inclusive of the rTSR modifier. However, payout will be capped at the target number of shares if the company’s absolute three year TSR is negative.

The PSU award earned will be credited with dividend equivalents from the grant date of the target award until the issuance date, assuming all dividends were reinvested in ADP stock at the time dividends are paid. The issuance of the applicable number of PSUs earned will be made in the form of shares of ADP stock in September following the conclusion of the three-year performance period.

Compensation Discussion and Analysis

Our adjusted net income growth for fiscal year 2025 was 10.6%, which resulted in an earned award level for the fiscal 2025 performance year in the amount of 141% of target (weighted 67%), and our revenue ex-ZMPT growth for fiscal year 2025 was 6.2%, which resulted in an earned award level for the fiscal year 2025 performance year in the amount of 115% of target (weighted 33%). These achievement percentages of target are applicable to the third of three tranches of the PSU award granted for fiscal year 2023 in September 2022, the second of three tranches of the PSU award granted for fiscal year 2024 in September 2023, and the first of three tranches of the PSU award granted for fiscal year 2025 in September 2024. Further details of the performance metrics adjusted net income and revenue ex-ZMPT can be referenced above under “2025 Incentive Compensation Performance Metrics.”

The adjusted net income growth and revenue ex-ZMPT growth goals were established consistent with the committee’s long-standing methodology in setting such goals and as such, align to the financial earnings guidance the company communicated in July 2024 for fiscal year 2025 and reflect ADP’s expectations and assumptions at that time.

The conclusion of fiscal year 2025 also marked the end of the three-year rTSR modifier measurement period for the fiscal year 2023 PSU award, granted in September 2022. During this three-year period ending June 30, 2025, ADP’s total shareholder return was 55.3%, which resulted in a ranking at the 68.1 percentile among the S&P 500 peers, and a final rTSR modifier achievement of +114.5%.

PSU Financial Metrics Performance Table

Subject to final performance assessment based on the three-year rTSR modifier (as discussed below), the following table shows the annual targets, results and awards levels achieved for fiscal 2025, as applicable to outstanding PSU awards granted in September 2022, September 2023, and September 2024, in each case as a percentage of target:

2 | Fiscal year 2023 achievement percentage on a weighted basis is 117% of target, which applies to the first of three tranches of the PSU award granted in September 2022. Fiscal year 2024 achievement percentage on a weighted basis is 111% of target, which applies to the second of three tranches of the PSU award granted in September 2022, and the first of three tranches of the PSU award granted in September 2023. Fiscal year 2025 achievement percentage on a weighted basis is 132% of target, which applies to the third of three tranches of the PSU granted in September 2022, the second of three tranches of the PSU award granted in September 2023, and the first of three tranches of the PSU award granted in September 2024.

Award levels achieved for each fiscal year in the three-year performance period are, as a percentage of target, 50% for threshold performance, 100% for target performance, 175% for stretch performance, and 0% for below threshold performance. The award level achieved within each range, as a percentage of target, is determined by

linear interpolation between the lower and upper bounds. Dividends are paid only with respect to shares of ADP stock that have been issued in connection with PSUs earned.

Relative TSR Modifier

PSU awards are subject to an rTSR modifier based on performance against the S&P 500 over the full three-year performance period. The S&P 500 was chosen because the index consists of a broad group of companies that represent investors’ alternative capital investment opportunities, thereby aligning the PSU payout opportunity to the long-term investment experience of our stockholders. The rTSR measurement is based on the average of the last

twenty trading days ending on the start and end of the three-year period (beginning July 1 and ending June 30). Relative performance against the S&P 500 may adjust the final three-year average payout percentage, based on achievement of adjusted net income growth and revenue ex-ZMPT growth, between 80% and 120%, as shown in the table below. Reflected in the table is the final three-year rTSR modifier performance and achievement applied to the fiscal year 2023 PSU award.

Relative TSR Performance (Percentile Rank) | Modifier Adjustment Achieved | PSU Three-Year rTSR Percentile Rank and Modifier Achieved(1)
> = 75P | 120% |
Between 25P – 75P | Interpolated (50P = 100%) | 68.1P; +114.5%
< = 25P | 80% |

1 | rTSR for the fiscal year 2023 PSU award, granted in September 2022, was measured against the S&P 500 over the period beginning July 1, 2022 and ending June 30, 2025.

The maximum payout opportunity for PSU awards inclusive of the modifier adjustment is capped at 200% of target, however, the payout opportunity is capped at 100% if our company’s absolute three-year TSR is negative.

The final rTSR assessment for the awards granted September 2023 and September 2024 will not be completed until June 30, 2026 and June 30, 2027 respectively.

Fiscal Year 2023 PSU Award Achievement

Based on the aforementioned performance levels of the fiscal year 2023 PSU award, the final award level earned as a percentage of target was 137%, as reflected in the table that follows.

FY |  | Financial Metric Weighted Achievement(1) |  | Three-Year Average Financial Achievement |  | Three- Year rTSR Modifier Achievement |  | Final Payout Achievement
2025 |  | 132% |  |  |  |  |  |
2024 |  | 111% |  | 120% | x | 114.5% | = | 137%
2023 |  | 117% |  |  |  |  |  |

1 | Weighted achievement for each fiscal year is based on 67% adjusted net income performance and 33% revenue ex-ZMPT performance.

Time-Based Restricted Stock Units

For fiscal year 2025, we granted RSUs to our executive officers, which vest ratably over three years, and allow for a portion of our NEOs’ LTI compensation to be more predictable from a realized value perspective, while being directly tied to the stockholder experience. We determine target award ranges based on our annual review of our long-term incentive compensation programs.

The committee may, from time to time, grant RSU awards to our executive officers that are outside of the annual grant cycle. These grants assist us in the recruitment, promotion and retention of executive officers and, while used only occasionally, are important in building our leadership team and succession strategy. In fiscal year 2025, none of the NEOs were granted RSUs outside of the annual grant cycle.

Other Compensation Components and Considerations

In addition to the compensation components discussed above and the opportunity to participate in the same Employees’ Savings-Stock Purchase Plan and health and welfare benefits available to our U.S. associates generally, we offer our executive officers retirement benefits, deferred compensation, limited perquisites, and change in control and severance protection. We believe these additional benefits are fair, competitive, consistent with our overall compensation philosophy and designed to ensure that we can effectively retain our executive officers as well as effectively compete for executive talent.

Retirement Benefits

All U.S. executive officers can participate in our 401(k) Plan, including our NEOs. Our NEOs, with the exception of Mr. McGuire, also participated in the Pension Retirement Plan, a tax-qualified, defined benefit, cash balance pension plan. The Pension Retirement Plan was closed to new participants as of January 2015 and was frozen as of July 1, 2020. Effective as of July 1, 2020, the matching contribution under our 401(k) Plan for participants impacted by the Pension Retirement Plan freeze was increased to $1.00 for every $1.00 a participant contributes up to 6% of eligible pay. Previously, Pension Retirement Plan participants received a 401(k) matching contribution of up to $0.70 for every $1.00 up to 6% of eligible pay. The committee approved these changes in 2020 to align our retirement programs to the market.

In addition, Messrs. Ayala and Bonarti participated in the Supplemental Officers Retirement Plan (“SORP”), a non-qualified, defined benefit plan which provides retirement benefits in excess of those generally available under the Pension Retirement Plan. The SORP was closed to new participants beginning in January 2014 and was frozen effective July 1, 2019, with no future accruals due to pay and/or service. As of July 1, 2019, Messrs. Ayala and Bonarti were automatically enrolled in the Automatic Data Processing, Inc. Executive Retirement Plan, a non-qualified, defined contribution plan in which the other NEOs participate, and which provides supplemental retirement benefits in excess of amounts available under our tax-qualified pension and other retirement plans.

Deferred Compensation

U.S. executive officers may defer all or a portion of their annual cash bonuses into a deferred compensation account. We make this program available to our executive officers to be competitive, to facilitate the recruitment of new executives and to provide our executive officers with a tax-efficient way to save for retirement. The company does not match deferrals for its NEOs or otherwise contribute any amounts to the NEOs’ deferred compensation amounts. Since the deferral accounts are made up of funds already earned by the executive officers, we do not consider the executive’s deferred account balances, or investment earnings or losses on such balances, when we make compensation decisions.

Perquisites

We provide each of our executive officers the use of automobiles leased by the company. Consistent with our policy towards all attendees, we pay for the spouses of our executive officers to accompany them to our annual sales President’s Club events, and in limited circumstances, to other company-sponsored events. In addition, the ADP Foundation makes contributions that match the charitable gifts made by our U.S. executive officers up to a maximum of $20,000 per calendar year and in fiscal year 2025, offered an additional match of up to a maximum of $20,000 for any donations made on Giving Tuesday.

Company policy permits Ms. Black (in her capacity as chief executive officer) to use the company’s aircraft for personal travel in order to maximize her business availability and productivity. Ms. Black is required to reimburse the company for the aggregate incremental cost in excess of $250,000 per fiscal year and is responsible for any income taxes in connection with any such personal use. In addition, Ms. Black may be provided with security in certain personal, non-business-related circumstances, as recommended by an independent third-party security firm’s risk assessment and validated by the company’s global security organization. The committee and the board consider these offerings to be in the best interest of the company by enhancing the safety and welfare of the company’s most critical executive, while allowing for increased focus, availability, and productivity on business matters during personal travel.

In accordance with the company’s standard policies available to all associates in the company’s relocation program, Mr. McGuire received tax reimbursement payments associated with a previous expatriate assignment.

Change in Control Arrangements

The Automatic Data Processing, Inc. Change in Control Severance Plan for Corporate Officers is designed to: (i) retain our corporate officers (including the NEOs) and (ii) align their interests with our stockholders’ interests so that they can consider transactions that are in the best interests of our stockholders and maintain their focus without concern regarding how any such transaction might personally affect them.

Our Change in Control Severance Plan for Corporate Officers is described in more detail below under “Potential Payments To Named Executive Officers Upon Termination or Change in Control.” Under this plan, our chief executive officer is entitled to severance equal to two times base salary and bonus upon termination of employment without cause or with good reason, while our other NEOs are entitled to severance equal to one and one-half times base salary and bonus. We believe that a higher severance multiple for our chief executive officer is needed in order to attract and retain the individual we believe is best suited for the position. Our chief executive officer is the individual the public and our stockholders most closely identify as the face of the company. The chief executive officer has the greatest individual impact on our success and faces the greatest personal financial risks when the company takes risks. Our Change in Control Severance Plan for Corporate Officers also provides that the vesting of all unvested equity awards would be accelerated under qualifying termination scenarios based on a “double-trigger” in which payments of cash and vesting of equity awards occur only if termination of employment without cause or by a participant for good reason occurs during the two-year period after a change in control.

Corporate Officer Severance Plan

ADP’s Corporate Officer Severance Plan is for purposes of involuntary terminations other than for cause in the absence of a change in control. This plan is designed to: (i) attract and retain executive officers by providing a level of protection against involuntary job loss, (ii) provide an

appropriate level of benefit to enable executive officers to transition to new employment, and (iii) as permitted by applicable law, secure a release and waiver of claims and compliance with restrictive covenants such as non-compete, non-solicitation, etc.

Our Corporate Officer Severance Plan is described in more detail below under “Potential Payments To Named Executive Officers Upon Termination or Change in Control.” In the event of a qualifying termination (i.e., an involuntary termination by the company without cause), executive officers are eligible to receive 18 months of base salary continuation (24 months for the chief executive officer), prorated bonus for year of termination, and continuation of vesting of equity awards during the salary continuation period, subject to proration in respect of certain performance-based equity awards. Mr. Ayala experienced a qualifying termination effective March 31, 2025 and, following satisfaction of the eligibility requirements for participation (i.e., execution of a release and waiver of claims and a restrictive covenant agreement), commenced receiving payments and benefits under the Corporate Officer Severance Plan, as further set forth on page 91. Mr. McGuire will experience a qualifying termination effective September 30, 2025 and, subject to satisfaction of the eligibility requirements for participation, is expected to commence receiving payments and benefits under the Corporate Officer Severance Plan in October 2025.

The severance formulas we use for executive officers are each designed to provide the level of temporary replacement income we feel is appropriate for that position.

Accounting and Tax Considerations

We consider accounting and tax implications when we design our equity-based and cash compensation programs and when we make awards or grants. However, the overriding consideration when evaluating the pay level or design component of any portion of our executives’ compensation is the effectiveness of the pay component and the stockholder value that management and the committee believe the pay component reinforces. Accordingly, the committee may award compensation that is not deductible if it is determined to be appropriate and in the best interests of the Company and our stockholders.

Compensation Discussion and Analysis

Clawback Policy

We have a rigorous Clawback Policy which exceeds the Nasdaq listing requirements and that provides the committee with discretion to recover both cash and equity incentive compensation from all current and former corporate officers (including any executive officers). A recipient’s award may be forfeited and required to be recovered, as applicable, if the recipient engages in activity that is in conflict with or adverse to our interests, including but not limited to fraud. In addition, effective December 1, 2023, the policy was updated in order to comply with current Nasdaq clawback listing standards, which require the mandatory clawback of incentive compensation in the case of financial restatement due to a material non-compliance with financial reporting requirements under the applicable federal securities laws.

No-Hedging and No-Pledging Policy

Our insider trading policy prohibits all of our directors and employees, including our executive officers, from engaging in any hedging or similar transactions involving ADP securities. The policy also prohibits all of our directors and employees, including our executive officers, from holding ADP securities in a margin account or pledging ADP securities as collateral for a loan. Our insider trading policy is available online on our corporate website at www.adp.com. To access this document, click on “About,” then “Corporate Responsibility,” and then “Ethics.”

Stock Ownership Guidelines

The committee has established stock ownership guidelines to encourage equity ownership by our executive officers in order to reinforce the link between their financial interests and those of our stockholders. We set the stock ownership guidelines on the basis of each executive officer’s pay grade, expressed as a multiple of the executive officer’s base salary on the first day of the fiscal year. Stock ownership (as defined under the guidelines) consists of shares of ADP common stock which are either owned outright by the executive officer or beneficially through ownership by direct family members (spouses and/or dependent children).

Under our stock ownership guidelines, Ms. Black is expected to own an amount of our stock equal in value to six times her base salary and our other NEOs are expected to own an amount of our stock equal in value to three times their respective base salaries. Executive officers whose ownership levels are below the minimum required levels are required to retain as shares of common stock at least 75% of post-tax net gains on stock option exercises, and 75% of shares (net of taxes) received upon vesting of RSUs or received under our PSU program. As of the end of fiscal year 2025, all NEOs met their respective stock ownership guideline.

| The awards for fiscal year 2023 are comprised of PSUs and RSUs for all NEOs. Consistent with the requirements of ASC Topic 718, the amounts relating to the PSUs for fiscal year 2023 represent the sum of (i) the grant date fair value of the third of three tranches of PSUs granted in September 2020, (ii) the grant date fair value of the second of three tranches of PSUs granted in September 2021 and (iii) the grant date fair value of the first of three tranches of PSUs granted in September 2022, and additionally for Ms. Black and Messrs.

For PSUs granted in fiscal years 2023, 2024, and 2025, tranches are linked to adjusted net income and revenue ex-ZMPT goals, and include a relative TSR modifier at the end of the respective three-year performance period. Remaining tranches of PSUs granted in fiscal year 2025 will be linked to adjusted net income and revenue ex-ZMPT goals for fiscal years 2026 and 2027, respectively, and will be reported in the Summary Compensation Table in such fiscal years. The remaining tranche of PSUs granted in fiscal year 2024 will be linked to adjusted net income and revenue ex-ZMPT goals for fiscal year 2026, and will be reported in such fiscal year. The grant date fair value of the PSUs granted in fiscal years 2025, 2024, and 2023, respectively, assuming achievement of the maximum level of performance are: Ms. Black, $21,068,602, $14,237,313, and $8,725,677; Mr. McGuire, $7,476,508, $6,018,596, and $4,201,121; Mr. Bonarti, $5,988,494, $4,987,310, and $4,738,237; Mr. DeSilva, $5,120,802, $3,609,314, and $2,123,071; Mr. Kutam, $5,408,622; and Mr. Ayala, $7,295,772, $6,650,057, and $6,204,392.
(2) | Performance-based bonuses paid under the annual cash bonus plan are shown in this column. A discussion of our annual cash bonus plan may be found in our Compensation Discussion and Analysis under “Cash Compensation - Annual Cash Bonus.”
(3) | Amounts shown reflect the aggregate increase during the last fiscal year in the present value of the executive’s benefit under our tax-qualified cash balance pension plan, the Automatic Data Processing, Inc. Pension Retirement Plan, and our non-qualified supplemental retirement plan, the Supplemental Officers Retirement Plan (“SORP”). Our SORP was frozen as of July 1, 2019. Therefore, actual accrued SORP benefits will not change going forward. However, the Change in Pension Value disclosed in column (h) will fluctuate from year-to-year, reflecting annual changes in the underlying discount rates and mortality rates. There were no above-market or preferential earnings on nonqualified deferred compensation. The Pension Retirement Plan and the SORP provide benefits in the form of a lump sum and/ or an annuity. We calculated the present value as of June 30, 2022 based on the Pri-2012 mortality table projected generationally using scale MP-2021 (with a white collar adjustment for the SORP only), a 3.25% interest crediting rate for the pension retirement plan, and a 4.60% discount rate; the present value as of June 30, 2023 is based on the Pri-2012 mortality table projected generationally using scale MP-2021 (with a white collar adjustment for the SORP only), a 3.50% interest crediting rate for the pension retirement plan, and a 5.10% discount rate; the present value as of June 30, 2024 is based on the Pri-2012 mortality table projected generationally using scale MP-2021 (with a white collar adjustment for the SORP only), a 3.70% interest crediting rate for the pension retirement plan, and a 5.40% discount rate; and the present value as of June 30, 2025 is based on the Pri-2012 mortality table projected generationally using scale MP-2021 (with a white collar adjustment for the SORP only), a 3.85% interest crediting rate for the pension retirement plan, and a 5.35% discount rate. During fiscal year 2025, Mr. Ayala elected a distribution of his Pension Retirement Plan balance, as reflected in the Pension Benefits for Fiscal Year 2025 table.

Incremental cost is calculated by multiplying the personal flight time including empty aircraft positioning time, by the aircraft’s hourly variable operating cost. Variable operating cost includes maintenance, fuel, cleaning, landing fees, flight fees, catering, and crew travel expenses, including hotels, meals and transportation. Ms. Black is responsible for any income taxes related to personal use. In connection with business travel by Mr. DeSilva in August 2024 to a company sales event, certain of Mr. DeSilva’s immediate family members accompanied him on the company’s aircraft. There was no aggregate incremental cost to the company for the aircraft-related travel of these immediate family members, and Mr. DeSilva was responsible for any income taxes of such use by his family members.
(e) | Amount paid by the company on behalf of the executives and their spouses or significant others who accompanied them in connection with company events sponsored by the company: Mr. McGuire, $5,018; Mr. DeSilva, $3,056; and Mr. Ayala, $6,708.

Restricted Stock Units/Performance Stock Units

We grant restricted stock units under our amended and restated 2018 Omnibus Award Plan (“2018 Omnibus Award Plan”).

Restricted stock unit (“RSU”) awards vest over periods determined by our compensation and management development committee (the “committee”). We also grant performance-based stock unit (“PSU”) awards to our senior executives which vest based on financial objectives that are measured over a three-year performance cycle comprised of three one-year performance periods, subject to a relative total shareholder return modifier measured over the full three-year performance cycle. Recipients of RSU awards whose home country is the United States are entitled to receive dividend equivalents, payable in cash, in respect of all unvested RSUs. Recipients of PSU awards receive dividend equivalents with respect to the target number of shares of stock subject to the PSUs, from the grant date of the target award until the issuance date, and assuming all dividend equivalents were reinvested in ADP stock at the time regular dividends are paid. Such reinvested dividend equivalents are distributed only with respect to shares of ADP stock that have been issued in connection with PSUs earned. We require that participants agree to be bound by a restrictive covenant containing non-compete, non-solicitation, and confidentiality obligations as a condition to the grant of RSUs and PSUs, as permitted by applicable law.

Awards of RSUs and PSUs may receive different vesting treatment outside the standard schedule for certain events as described below.

For RSUs:

● | granted effective September 1, 2022, if, after reaching the first anniversary of the grant date, a participating senior executive’s employment with the company is terminated due to retirement (defined as voluntary termination of employment at or after age 55 with 10 years of service), such senior executive will be entitled to continued vesting of the RSUs in accordance with the normal vesting schedule set forth in the applicable award agreement (or accelerated vesting on the termination date for senior executives with a home country outside the United States).
● | granted effective September 1, 2023, if, after reaching January 1 of the fiscal year of the grant date, a participating senior executive’s employment with the company is terminated due to retirement (defined as voluntary termination of employment at or after age 55 with 10 years of service), such senior executive will be entitled to continued vesting of the RSUs in accordance with the normal vesting schedule set forth in the applicable award agreement (or accelerated vesting on the termination date for senior executives with a home country outside the United States). If a participant’s employment is terminated due to death or disability, vesting is accelerated on the termination date.

Compensation of Executive Officers

For PSUs:

● | granted prior to September 1, 2023, if, after completion of the first measurement year of the three-year performance period, a participant’s employment with the company is terminated prior to the expiration of the performance period due to death, disability or retirement (defined as voluntary termination of employment at or after age 65, or age 55 with 10 years of service), a participant will be entitled to receive a prorated portion (based on the number of completed months in the performance period through the date of termination of employment, divided by 36) of the PSUs earned for such performance period, with settlement of such PSUs (if any) occurring in accordance with the normal vesting schedule set forth in the applicable award agreement (which, in the case of death or disability, including any death or disability occurring after retirement, prorated PSUs earned will be subject to accelerated vesting and determined by assuming 100% achievement for each measurement year in the performance period not completed prior to the participant’s death or disability, inclusive of the modifier metric).
● | granted effective September 1, 2023, if, after reaching January 1 of the fiscal year of the grant date, a participant’s employment with the company is terminated prior to the expiration of the performance period due to retirement (defined as voluntary termination of employment at or after age 65, or age 55 with 10 years of service), a participant will be entitled to receive continued vesting of the PSUs, subject to adjustment based on actual performance

achievement, with settlement of such PSUs (if any) occurring in accordance with the normal vesting schedule set forth in the applicable award agreement. If, after reaching January 1 of the fiscal year of the grant date, a participant’s employment with the company is terminated prior to the expiration of the performance period due to death or disability (or if such participant’s death or disability occurs after retirement), a participant will be entitled to receive on the date of such death or disability accelerated vesting of the PSUs earned for such performance period (assuming 100% achievement for each measurement year in the performance period not completed prior to the participant’s death or disability, inclusive of the modifier metric).

Except as described above or as otherwise determined by the committee (or, in the case of PSUs, as specified in an applicable award agreement), the unvested portion of any RSUs and all outstanding PSUs, including any applicable dividend equivalents, are forfeited without consideration upon the participant’s termination of employment.

RSU and PSU awards under our 2018 Omnibus Award Plan allow (or require, in cases of financial restatement under our Clawback Policy, as appropriate) the committee to cause a recipient’s award to be forfeited, and to require the recipient to pay to the company any gain realized on the award, if the recipient engages in an activity that is in conflict with or adverse to the company’s interests, including but not limited to fraud or conduct contributing to any financial restatements or irregularities, or if the recipient violates a restrictive covenant.

Stock Options

Starting with fiscal year 2023, we no longer grant stock options. Previously, we granted stock options under our 2018 Omnibus Award Plan with an exercise price equal to our closing stock price on the date of grant. Prior to the approval of the 2018 Omnibus Award Plan by our stockholders in November 2018, we granted stock options under our previous amended and restated 2008 Omnibus Award Plan (the “Prior Plan”).

No option may be exercised after the expiration of its ten-year term, and awards generally vest over a 4-year period. We require that participants agree to be bound by a restrictive covenant containing non-compete, non-solicitation, and confidentiality obligations as a condition to the grant, as permitted by applicable law.

Stock options granted under our 2018 Omnibus Award Plan become fully vested and exercisable upon the death or disability of an option holder who (i) is an active employee, (ii) satisfied the company’s retirement criteria and retired on or after age 55 with 10 years of service (“Normal Retirement”), or (iii) retired in the previous twelve months on or after age 55 with between five and 10 years of service. Stock options will continue to vest following a Normal Retirement that occurs after the first anniversary of an option’s grant date.

Vested options granted under our 2018 Omnibus Award Plan (and Prior Plan, as applicable) may generally be exercised for up to 60 days following an option holder’s termination of employment with the company (or per past company practice, the severance end date, if later), provided that:

● | option holders who retire on or after Normal Retirement will have 37 months following retirement (or per past company practice, the severance end date, if later) to exercise their vested options (subject to extension in the case of subsequent death);
● | option holders who retire on or after age 55 with between five and 10 years of service will have 12 months following retirement (or per past company practice, the severance end date, if later) to exercise their vested options (subject to extension in the case of subsequent death);

● | option holders who die or become disabled on or after eligibility for Normal Retirement will have 36 months following their death or disability to exercise their vested options (subject to extension in the case of subsequent death following a disability); and
● | option holders who were not eligible for Normal Retirement on the date of death or disability will have 12 months following their death or disability to exercise their vested options (subject to extension in the case of subsequent death following a disability).

Stock option awards under our 2018 Omnibus Award Plan (and Prior Plan, as applicable) allow our committee to cause a recipient’s award to be forfeited, and to require the recipient to pay to the company any option gain, if the recipient engages in an activity that is in conflict with or adverse to the company’s interests, including but not limited to fraud or conduct contributing to any financial restatements or irregularities, or if the recipient violates a restrictive covenant.

Automatic Data Processing, Inc. Pension Retirement Plan

The Pension Retirement Plan (“Pension Retirement Plan”) is a tax-qualified defined benefit plan covering U.S. employees of the company. The Pension Retirement Plan was closed to new participants as of January 2015 and was frozen as of July 1, 2020. Participants retained their accrued benefit as of June 30, 2020 with no future accruals due to pay and/or service. Accounts continue to earn interest based upon the ten-year U.S. Treasury constant maturity rates. A participant must have three years of service to receive any benefit.

Prior to the freeze, the company credited participants’ notional accounts with annual contributions which were determined based upon base salary and years of service. The contributions ranged from 2.1% to 10% of base salary.

Compensation used to determine the benefits in any given year is limited to calendar year base salary up to the IRS compensation limit in effect for the plan year.

Effective as of July 1, 2020, the matching contribution under our 401(k) Plan for participants impacted by the Pension Retirement Plan freeze was increased to $1.00 for every $1.00 a participant contributes up to 6% of eligible pay. Previously, Pension Retirement Plan participants received a 401(k) matching contribution of up to $.70 for every $1.00 up to 6% of eligible pay. The compensation and management development committee approved these changes in 2020 to align our retirement programs to the market.

Supplemental Officers Retirement Plan

The company sponsors a Supplemental Officers Retirement Plan (“SORP”), which is a non-qualified defined benefit plan that pays a lump sum or an annuity upon retirement. Eligible participants include certain NEOs. Since July 1, 2019, the SORP has been frozen. Participants retain their accrued benefit as of June 30, 2019 with no future accruals due to pay and/or service. The SORP was previously closed to new entrants in January 2014. On August 14, 2008, our board of directors approved amendments to the SORP, which implemented changes to the SORP benefits formula and the early retirement factors, in each case, used for any active employee not already earning a benefit by January 1, 2008 or any participant who had not attained age 50 by January 1, 2009, as well as changes relating to the forms of benefit available for all current and future participants.

On November 10, 2009, our board of directors approved additional amendments effective January 1, 2010, to provide that for both benefit accrual and vesting credit, service will be determined based on the number of months elapsed from the later of a participant’s entry into the plan and January 1, 1989, and subject, in the case of vesting, to a schedule set forth in the SORP, and also provide that effective after December 31, 2009, our chief executive officer would no longer be able to grant service credit in his/her discretion to SORP participants who are involuntarily terminated or who receive severance from the company.

All participants must have at least five years of service to receive any benefit under the SORP. After 10 years of service, a participant will qualify for the full annual benefit. We refer to the percentage of the benefit that has been earned by a participant as the “vested percentage.” The vested percentage is determined using a schedule set forth in the SORP.

SORP benefits begin on the earliest of (i) the later of attainment of age 60 and the first day of the seventh month following separation from service, (ii) disability, and (iii) death. Participants can receive their benefits in the form of a single life annuity, a 25%, 50%, 75%, or 100% joint and survivor annuity with a beneficiary, or a ten-year certain and life annuity. Subject to rules required under Section 409A of the Internal Revenue Code, participants may generally also elect to have either 25% or 50% of their benefits paid in a single lump sum. A participant who terminates employment by reason of disability is eligible to receive an unreduced benefit payable as of the participant’s termination. Upon the death of a participant, the participant’s surviving spouse or other designated beneficiary is eligible to receive a 50% survivor benefit, payable as a life annuity or, if elected, a guaranteed payment for 120 months only.

Compensation of Executive Officers

The amount of the annual benefit is determined by multiplying the participant’s final average annual pay by a factor of 2%, the number of years of service (up to 20 years), and the participant’s vested percentage. For participants with more than 20 years of service only, added to that first amount will be an amount determined by multiplying the participant’s final average annual pay by a factor of 1%, up to five additional years of service, and the participant’s vested percentage.

Final average annual pay will be based on salary, bonuses, and incentive payment awards, excluding any stock-based awards. The maximum annual plan benefit that may be paid will be limited to 45% of a participant’s final average annual pay. A participant whose benefit payments

begin before the first day of the month on or after the participant’s 65th birthday will receive payments reduced at a rate of 4/12 of 1% per month for each month (up to 36 months) by which the participant’s benefit commencement precedes the participant’s 65th birthday, and, if applicable, further reduced at a rate of 5/12 of 1% for each month by which the benefit commencement precedes the participant’s 62nd birthday.

If within 24 months after a participant’s employment terminates he or she violates the non-competition provisions of any agreement such participant has entered into with the company, such participant will forfeit all of his or her benefits under the SORP.

Deferred Compensation Program

Under the ADP Deferred Compensation Plan, all U.S. executives of the company (including the NEOs) can defer all or a portion of their annual cash bonuses, which may be allocated to notional investments selected by the participant. Participants can choose to invest their notional account in any of the investment funds that closely mirror the investment options available in the company’s 401(k) Plan. Deferrals made prior to 2015 could have been invested in a fixed income fund, which is adjusted each fiscal year, and was 5.00% for fiscal year 2025. The company does not match deferrals by the NEOs or otherwise contribute any amounts to their deferred compensation accounts.

Each participant has the option of making a one-time election changing the timing and/or the form of distributions from his or her account. Any such change must comply with the “redeferral rules” in effect under

Section 409A of the Internal Revenue Code and may be used only to delay the timing and/or change the number of payments to be received. Participants may elect to receive payments of their deferred funds either in a lump sum payment or in installments. However, in the event of death, disability, or termination of employment prior to age 65, or age 55 with 10 years of service, payments are made in a lump sum regardless of a participant’s election. Deferred funds and the earnings on such deferrals made for fiscal year 2005 and later may be distributed to a participant following separation from service only after a six-month delay. Distributions are subject to federal, state, and local income taxes on both the principal amount and investment earnings at the ordinary income rate in the year in which such payments are made.

Executive Retirement Plan

The Automatic Data Processing, Inc. Executive Retirement Plan (“ERP”) is a non-qualified defined contribution plan that provides supplemental retirement benefits in excess of amounts available under the company’s other tax-qualified and non-qualified retirement plans. NEOs and other U.S. corporate officers of the company are eligible to participate in the ERP and are automatically enrolled. When our SORP

was frozen effective July 1, 2019, Messrs. Bonarti, and Ayala, who participated in the SORP, were automatically enrolled in the ERP.

The ERP provides an annual contribution equal to 8% of total salary and bonus, less any contributions provided in the same plan year by the company’s other qualified and

non-qualified retirement plans. Company contributions are credited to a participant’s account following the end of the applicable plan year. Participants can choose to invest their notional account in any of the investment funds that closely mirror the investment options available in the company’s 401(k) Plan. A participant’s account will be 100% vested after three years of continuous service with the company, or upon death or disability.

A participant will forfeit all of his or her benefits under the ERP if the participant’s employment is terminated for cause or if, while employed, or within 24 months after a participant’s employment terminates, he or she violates a non-competition, non-solicitation or non-disclosure provision of any agreement between the participant and the company.

Participants may elect to receive distributions from the ERP either in a lump sum payment or in annual installments. Each participant has the option of making a one-time election to change the form of distribution from his or her account. Any such change must comply with the rules in effect under Section 409A of the Internal Revenue Code. Contributions and earnings on such contributions are distributed to a participant following separation from service only after a six-month delay. However, in the event of death or if, upon separation from service a participant’s account balance is less than $50,000, payments are made in a lump sum regardless of a participant’s election.

Canada Supplementary Excess Retirement Plan

The ADP Canada Co. Supplementary Excess Retirement Plan (“SERP”) provides supplemental retirement benefits for individuals whose combined contributions under the Group Registered Retirement Savings Plan (“RRSP”) in a plan year are capped due to Canada Revenue Agency RRSP salary limits. Executives (including corporate officers) of ADP Canada Co. are eligible to participate in the SERP and are automatically enrolled.

The SERP provides an annual contribution equal to 6% of total salary and bonus up to the annual salary limit. Company contributions are credited to a participant’s notional account each pay period. Participants can choose to invest their notional account in any of the investment funds available in the Canada Group RRSP (provided the funds are permissible under a notional plan). A participant’s account will be 100% vested after three months of continuous service with the company, or upon death or disability.

A participant’s benefit will be distributed in a lump sum or, if the participant is over the age of 55 and the account balance is over C$50,000, in annual installments. In addition, a participant may transfer all or a portion of the account balance to the Canada Group RRSP if contribution room is available.

Potential Payments to Named Executive Upon Termination or Change in Control

Change in Control Severance Plan for Corporate Officers

We maintain the Automatic Data Processing, Inc. Change in Control Severance Plan for Corporate Officers, which provides for the payment of specified benefits to officers selected by the board of directors if their employment terminates under certain circumstances after a change in control of the company. All NEOs participate in the change in control plan. As of June 30, 2025, there were 29 eligible participants in the change in control plan.

The change in control plan provides that a participant who is involuntarily terminated by the company without cause or who leaves for good reason during the two-year period following the occurrence of a change in control will receive:

● | A lump sum payment equal to 150% (or in the case of our chief executive officer, 200%) of such participant’s current total annual compensation;
● | Full vesting of his or her stock options;
● | Full vesting of any restricted shares or units; and
● | The number of shares the participant would have been entitled to receive under the then-ongoing performance-based equity programs had all applicable performance goals been achieved at 100% target rate.

A participant’s current total annual compensation equals his or her highest rate of annual salary during the calendar year in which his or her employment terminates or the year immediately prior to the year of such termination, plus his or her average annual cash bonus compensation earned in respect of the two most recent calendar years immediately preceding the calendar year in which his or her employment terminates. Equity-based long-term incentives are excluded from the definition of total annual compensation.

The change in control plan defines “good reason” as the occurrence of any of the following events after a change in control without the participant’s written consent:

● | A material diminution in the participant’s position, duties, responsibilities, or authority as of the date immediately prior to the change in control; or
● | a reduction in a participant’s base compensation or a failure to provide incentive compensation opportunities at least as favorable in the aggregate as those provided immediately prior to the change in control; or

● | a failure to provide employee benefits at least as favorable in the aggregate as those provided immediately prior to the change in control; or
● | a failure of any successor of the company to assume in writing the obligations under the change in control plan.

The change in control plan defines “cause” as:

● | gross negligence or willful misconduct by a participant, which is materially injurious to the company, monetarily or otherwise;
● | misappropriation or fraud with regard to the company or its assets;
● | conviction of, or the pleading of guilty or nolo contendere to, a felony involving the assets or business of the company; or
● | willful and continued failure to substantially perform one’s duties after written notice by the board of directors.

The change in control payments potentially due to the NEOs are payable solely pursuant to the terms of the change in control plan and applicable terms of the award agreements.

A “change in control” will have occurred under the change in control plan if:

● | any “person” (as defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as amended), excluding the company, any subsidiary of the company, or any employee benefit plan sponsored or maintained by the company (including any trustee of any such plan acting in its capacity as trustee), becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of securities of the company representing 35% or more of the total combined voting power of the company’s then-outstanding securities;
● | there occurs a merger, consolidation, or other business combination of the company (a “transaction”), other than a transaction immediately following which the stockholders of the company, immediately prior to the transaction, continue to be the beneficial owners of securities of the resulting entity representing more than 60% of the voting power in the resulting entity, in

83 | | Automatic Data Processing, Inc. – Proxy Statement

Table of Contents

Potential Payments to Named Executive Officers Upon Termination or Change in Control

| substantially the same proportions as their ownership of the company voting securities immediately prior to the transaction; or
● | there occurs the sale of all or substantially all of the company’s assets, other than a sale immediately following which the stockholders of the company immediately prior to the sale are the beneficial owners of securities of the purchasing entity representing more than 60% of the voting power in the purchasing entity, in substantially the same proportions as their ownership of the company voting securities immediately prior to the sale of assets.

The company will reduce payments under the change in control plan to avoid the application of excise taxes pursuant to Section 4999 of the Internal Revenue Code, unless the after-tax amount to be received by a participant without such a reduction would be greater than the after-tax amount that would be received after such reduction. All payments under the plan are conditioned upon the participant’s execution of a release of claims in favor of the company.

Corporate Officer Severance Plan

Effective May 6, 2015, ADP adopted the Corporate Officer Severance Plan for purposes of involuntary terminations other than for cause in the absence of a change in control.

All NEOs participate in the severance plan. As of June 30, 2025, there were 29 eligible participants in the severance plan.

The severance plan provides that a participant who is involuntarily terminated by the company without cause (other than during the two-year period following the occurrence of a change in control) will receive:

● | 18 (or in the case of the CEO, 24) months of continued base salary;
● | A prorated annual bonus for the year of termination, based on actual performance for the full fiscal year, but assuming that any non-financial and other subjective and qualitative performance criteria are achieved at a level equal to the weighted-average percentage achievement of all applicable financial and other objective and non-qualitative performance criteria;
● | Continued vesting of his or her stock options and time-vested restricted stock and restricted stock unit awards during the period of continued base salary payments (the “Severance Period”); and
● | The number of shares of stock (or cash, in the case of cash-settled awards) that the participant would have been entitled to receive based on the actual achievement

| of the applicable performance goals in each of the then-ongoing performance-based restricted stock and PSU programs, prorated to reflect the portion of the applicable performance period elapsed through the last day of the Severance Period.

The severance plan defines “cause” as:

● | Failure to perform duties (other than due to physical or mental illness or injury), which failure amounts to an intentional and extended neglect of duties, to the extent not cured within 15 days following written notice;
● | Engaging in conduct that is materially injurious to the company or an affiliate;
● | Conviction of, or the pleading of guilty or nolo contendere to, a felony involving as a material element fraud or dishonesty; or
● | The consistent failure to follow the lawful instructions of the board of directors or a direct superior, which failure amounts to an intentional and extended neglect of duties.

The severance payments potentially due to the NEOs are payable solely pursuant to the terms of the severance plan (other than if benefits are payable pursuant to the change in control plan).

Certain executives, including the NEOs, who terminate employment with the company after they have attained age

55 and been credited with 10 years of service are eligible to participate in the company’s executive retiree medical plan.

Deferred Compensation

Under the ADP Deferred Compensation Plan, all U.S. executives of the company (including the NEOs) can defer into a deferred compensation account all or a portion of their annual cash bonuses to be payable following

separation from the company. For a description of the ADP Deferred Compensation Plan and aggregate deferred compensation for our NEOs at June 30, 2025, see “Deferred Compensation Program” above.

Termination and Change in Control Tables

The following tables set forth the payments that each of our NEOs who were serving as executive officers as of June 30, 2025, would have received under various termination scenarios on June 30, 2025. Pension benefits, which are described under “Pension Benefits for Fiscal Year 2025” above, and deferred compensation balances, which are described under “Deferred Compensation Program” above, are not included in the tables below in accordance with applicable information statement disclosure requirements except to the extent of any incremental value payable in any of such termination scenarios. Pursuant to the company’s Corporate Officer Severance Plan, each of our NEOs

would also receive a prorated annual bonus for the year of termination, based on actual performance for the full fiscal year, in the event of an involuntary termination without cause prior to June 30, 2025. Please refer to page 84 in this proxy statement for a description of the Corporate Officer Severance Plan. With regard to the payments on a change in control, the amounts detailed below presume that (x) the change in control includes a change in control of the company and (y) each NEO’s employment was terminated by the company without cause or by the executive for good reason within two years following the change in control occurring on June 30, 2025.

CEO Pay Ratio

In accordance with the requirements set forth by the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Pay Ratio Rule”), we are providing the following information to disclose the annual compensation of our CEO, Ms. Black, compared to the annual compensation of the median associate of our workforce (not including Ms. Black). For fiscal year 2025, an estimate of this ratio is 284:1, and is based on Ms. Black’s 2025 Summary Compensation Table total of $19,137,192 and the 2025 total of our median associate of $67,434.

To arrive at the ratio and calculate the median associate’s compensation, we first identified our active global workforce as of April 1, 2025, inclusive of full-time, part-time, and temporary workers, which consisted of 67,071 associates (excluding our CEO). Consistent with permitted adjustments allowed under the Pay Ratio Rule, we then applied the de minimis exemption to exclude all associates in the Philippines (2,828), totaling 4.22% of the associate population. After applying the exemption, we ranked the remaining associate population based on annualized gross earnings, as reflected in our global payroll records, for the period covering April 1, 2024 through March 31, 2025. For associates located outside the home jurisdiction of our CEO, the United States, annualized gross earnings were converted to U.S. dollars using an average daily foreign exchange rate over the same time period. The median associate was then identified, and the

associate’s compensation was calculated using the same methodology used to calculate the compensation of our NEOs, as reflected in the Summary Compensation Table on page 64.

The SEC rules for identifying the median employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. We believe that our calculated ratios are reasonable estimates calculated in a manner consistent with the pay ratio disclosure requirements. The executive compensation philosophy and principles set forth on page 49 also underlie the company’s overall compensation program for employees. Pay ratios reported by other companies, including those within our Peer Group and industry, may not be comparable to the pay ratio reported above, as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

This information is being provided for the purposes of compliance with the pay ratio disclosure requirement. Neither the compensation and management development committee nor management of the company used the pay ratio measure in making compensation decisions.

Financial Performance Measures Tabular List

The following table lists the financial performance measures, on an unranked basis, that we believe are most important in linking compensation actually paid to company performance for the most recently completed fiscal year.

Measure / Metric |  | Compensation Program
Revenue Growth |  | Annual Cash Bonus
New Business Bookings Growth |  | Annual Cash Bonus
Adjusted EBIT Growth(1) |  | Annual Cash Bonus
Adjusted Net Income Growth |  | Long-term Incentive (PSU)
Revenue ex-ZMPT Growth(2) |  | Long-term Incentive (PSU)

1 | Our adjusted EBIT measure excludes the impact of taxes, certain interest expense, certain interest income, and certain other items. We continue to 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. Refer to the table in Appendix A for a reconciliation from net earnings to adjusted EBIT for fiscal years 2025 and 2024.
2 | Our revenue ex-ZMPT measure is a consolidated revenue growth measure that excludes the impact of zero-margin benefits pass-throughs. Importantly, the PSU revenue metric is not duplicative of the annual cash bonus plan revenue metric due to the exclusion of zero-margin benefits pass-throughs. Refer to the table in Appendix A for further detail on this item and a reconciliation from consolidated revenue to revenue ex-ZMPT for fiscal years 2025 and 2024.

Audit Committee Report

The audit committee oversees the financial management and financial reporting procedures of the company, and the appointment, compensation, retention and performance of the company’s independent auditors, on behalf of the board of directors. A further description of the role and members of the audit committee is set forth on page 21 under “Audit Committee.”

In fulfilling its oversight responsibilities, the committee reviewed and discussed the company’s audited financial statements with management, which has primary responsibility for the preparation of the financial statements. In performing its review, the committee discussed the propriety of the application of accounting principles by the company, the reasonableness of significant judgments and estimates used in the preparation of the financial statements, and the clarity of disclosures in the financial statements. Management represented to the audit committee that the company’s financial statements were prepared in accordance with generally accepted accounting principles. The committee also reviewed and discussed the company’s audited financial statements with Deloitte & Touche LLP, an independent registered public accounting firm, the company’s independent auditors for fiscal year 2025, which is responsible for expressing an opinion on the conformity of the company’s financial statements with generally accepted accounting principles in the United States of America. Deloitte & Touche LLP conducted its audit in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”).

During the course of fiscal year 2025, management completed the documentation, testing and evaluation of the company’s system of internal control over financial reporting in response to the requirements set forth in Section 404 of the Sarbanes- Oxley Act of 2002 and related regulations. The audit committee was kept apprised of the progress of the evaluation and provided oversight and advice to management during the process. In connection with this oversight, the audit committee received periodic updates provided by management and Deloitte & Touche LLP at each audit committee meeting. At the conclusion of the process, management provided the audit committee with, and the audit committee reviewed, a report on the effectiveness of the company’s internal control over financial reporting. The audit committee also reviewed the report of management contained in the annual report on Form 10-K for the fiscal year ended June 30, 2025 filed with the SEC, as well as Deloitte & Touche LLP’s Report of Independent Registered Public Accounting Firm included in the annual report on Form 10-K for the fiscal year ended June 30, 2025 related to its integrated audit of the consolidated financial statements and financial statement schedule, including the matters identified by Deloitte & Touche LLP as critical audit matters, and the effectiveness of internal control over financial reporting. The audit committee continues to oversee the company’s efforts related to its internal control over financial reporting and management’s preparations for the evaluation in fiscal year 2026.

The audit committee has discussed with Deloitte & Touche LLP the matters that are required to be discussed by PCAOB Auditing Standard 1301 (Communications with Audit Committees) and the SEC Rule 2-07. Deloitte & Touche LLP has provided to the committee the written disclosures and the letter required by applicable requirements of the PCAOB regarding Deloitte & Touche LLP’s communications with the audit committee concerning independence, and the committee discussed with Deloitte & Touche LLP, the firm’s independence, including the matters in those written disclosures. The committee also discussed with Deloitte & Touche LLP the overall scope and plan for its audit and engagement. The committee considered whether Deloitte & Touche LLP’s provision of non-audit services to the company and its affiliates and the fees and costs billed and expected to be billed by Deloitte & Touche LLP for those services impaired or compromised Deloitte & Touche LLP’s independence and concluded that those services did not. The audit committee has discussed with the company’s internal auditors and with Deloitte & Touche LLP, with and without management present, their respective evaluations of the company’s internal accounting controls and the overall quality of the company’s financial reporting.

The committee also discussed with management, and took into consideration when issuing this report, the Auditor Independence Policy, which prohibits the company or any of its affiliates from entering into most non-audit related consulting arrangements with its independent auditors. The Auditor Independence Policy is discussed in further detail below under “Independent Registered Public Accounting Firm’s Fees.”

Audit Committee Report

In addition, in accordance with SEC and PCAOB rules, independent audit partners are subject to rotation requirements limiting their number of consecutive years of service to no more than five. In connection with the completion of the company’s fiscal year 2025 audit, the lead audit partner from Deloitte & Touche LLP has rotated. The process for selecting the company’s lead audit partner included company management and the committee chair interviewing and vetting the candidates put forth by our independent auditor, with consultation by the full committee in connection with the final selection of the lead audit partner. The audit committee believes there are benefits to having an independent auditor with an extensive history with ADP including higher-quality audit work and accounting advice due to Deloitte & Touche LLP’s institutional knowledge of the company’s business and operations, accounting policies and financial systems, and internal control framework, as well as operational efficiencies and a competitive fee structure because of the firm’s familiarity with ADP’s business.

In addition to independence, in determining whether to reappoint Deloitte & Touche LLP as the company’s independent registered public accounting firm, the audit committee took into consideration a number of factors, including:

● | the breadth of experience and length of time Deloitte & Touche LLP has been engaged;
● | historical and recent performance on the company’s audit;
● | familiarity with our global operations and business;
● | the advisability and potential impact of selecting an entirely different and unaffiliated independent registered public accounting firm;
● | external data relating to audit quality and performance, including PCAOB inspection results on Deloitte & Touche LLP;
● | Deloitte & Touche LLP’s internal quality controls;
● | the appropriateness of Deloitte & Touche LLP’s fees; and
● | an assessment of the professional qualifications and past performance of the lead audit partner and auditing team of Deloitte & Touche LLP.

Based on the considerations referred to above, the audit committee recommended to the board of directors that the audited financial statements be included in our annual report on Form 10-K for the fiscal year ended June 30, 2025. In addition, the committee concluded that the appointment of Deloitte & Touche LLP is in the best interest of the company and its stockholders, and appointed Deloitte & Touche LLP as the independent auditors for the company for the fiscal year 2026, subject to the ratification by the stockholders at the 2025 Annual Meeting of Stockholders.

Independent Registered Public Accounting Firm’s Fees

In addition to retaining Deloitte & Touche LLP to audit the consolidated financial statements for fiscal year 2025 and fiscal year 2024, the audit committee retained Deloitte & Touche LLP to provide various services in fiscal year 2025

and fiscal year 2024. The aggregate fees billed by Deloitte & Touche LLP for fiscal year 2025 and fiscal year 2024 for these various services were:

Type of Fees |  | FY 2025 |  | FY 2024
|  | ($ in thousands)
Audit Fees |  | $10,533 |  | $10,087
Audit-Related Fees |  | 539 |  | 209
Tax Fees |  | 80 |  | 73
All Other Fees |  | 2 |  | 2
Total |  | $11,154 |  | $10,371

In the above table, in accordance with the SEC definitions, “audit fees” are fees we paid Deloitte & Touche LLP for professional services for the audit of the company’s consolidated financial statements included in our annual report on Form 10-K and review of financial statements included in our quarterly reports on Form 10-Q, services that are normally provided by Deloitte & Touche LLP in connection with statutory and regulatory filings or engagements or any other services performed by Deloitte & Touche LLP to comply with generally accepted auditing standards.

“Audit-related fees” are fees billed by Deloitte & Touche LLP for assurance and related services that are typically performed by the independent public accountant (e.g., due diligence services, employee benefit plan audits and internal control reviews). For fiscal years 2025 and 2024, “audit-related fees” include audit services rendered in connection with certain transactional activity and due diligence procedures, as well as certain benefit plan and trust audits.

“Tax fees” are fees for tax compliance, tax advice and tax planning. “All other fees” are fees billed by Deloitte & Touche LLP to the company for any services not included in the first three categories. For fiscal year 2025, Deloitte’s accounting research tool subscription is included in the “All Other Fees” category.

The board of directors has adopted an auditor independence policy that prohibits our independent auditors from providing:

● | bookkeeping or other services related to the accounting records or financial statements of the company;
● | financial information systems design and implementation services;

● | appraisal or valuation services, fairness opinions or contribution-in-kind reports;
● | actuarial services;
● | internal audit outsourcing services;
● | management functions or human resources services;
● | broker or dealer, investment adviser or investment banking services;
● | legal services and expert services unrelated to the audit; and
● | any other service that the Public Company Accounting Oversight Board or the Securities and Exchange Commission determines, by regulation, is impermissible.

The audit committee has adopted a policy requiring that all audit, audit-related and non-audit services be pre-approved by the audit committee. All services provided to us by the independent auditors in fiscal year 2025 and fiscal year 2024 were pre-approved by the audit committee. The independent auditors may only perform non-prohibited non-audit services that have been specifically approved in advance by the audit committee, regardless of the dollar value of the services to be provided. In addition, before the audit committee will consider granting its approval, the company’s management must have determined that such specific non-prohibited non-audit services can be best performed by the independent auditors based on its in-depth knowledge of our business, processes and policies. The audit committee, as part of its approval process, considers the potential impact of any proposed work on the independent auditors’ independence.

Stockholder Proposals and Nominations

If a stockholder intends to submit any proposal for inclusion in the company’s proxy statement for the company’s 2026 Annual Meeting of Stockholders in accordance with Rule 14a-8 under the Exchange Act, the proposal must be received by the corporate secretary of the company no later than May 28, 2026.

To be eligible to submit such a proposal for inclusion in the company’s proxy materials for an annual meeting, the proposal must meet the requirements of the rules of the SEC relating to stockholders’ proposals, including Rule 14a-8, which sets forth certain threshold and holding requirements, the permissible number and length of proposals, and other matters, including the circumstances in which the company is permitted to exclude proposals.

Advance Notice

Separate from the requirements of Rule 14a-8, relating to the inclusion of a stockholder proposal in the company’s proxy statement, the company’s amended and restated by-laws require advance notice for a stockholder to bring nominations of directors (other than a proxy access nomination, which is described below) or any other business to be considered at any annual meeting of stockholders. Specifically, our amended and restated by-laws require that stockholders wishing to nominate candidates for election as directors or propose any other business to be considered at our 2026 Annual Meeting of Stockholders must notify the company of their intent in a written notice delivered to the company in care of the company’s corporate secretary at our principal executive offices not less than 90 nor more than 120 days before the first anniversary of the date of the 2025 Annual Meeting of Stockholders, or November 12, 2026.

As a result, in order for the notice given by a stockholder to comply with our amended and restated by-laws, it must be received no earlier than July 15, 2026, and no later

than August 14, 2026, unless the date of our 2026 Annual Meeting of Stockholders occurs more than 30 days before or 60 days after the first anniversary of the 2025 Annual Meeting of Stockholders. In that case, our amended and restated by-laws provide that we must receive the notice no earlier than the 120th day prior to the date of the 2026 Annual Meeting of Stockholders and no later than the 90th day prior to the date of the 2026 Annual Meeting of Stockholders or the tenth day following the day on which we first make a public announcement of the date of the 2026 Annual Meeting of Stockholders, whichever is later.

Additionally, stockholders who intend to solicit proxies in support of director nominees other than the company’s nominees must comply with applicable Exchange Act requirements, including providing notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than September 14, 2026.

Proxy Access

Our by-laws have proxy access provisions that permit a stockholder, or a group of up to twenty stockholders that owns 3% or more of our stock continuously for at least three years, to nominate and include in our proxy materials candidates for election as directors. Such stockholder or group may nominate up to the greater of two individuals or 20% of our board of directors, provided that the stockholder or group and the nominee(s) satisfy the requirements specified in our by-laws. In order to be properly brought before the 2026 Annual Meeting of Stockholders, a stockholder’s notice of nomination of one or more director candidates pursuant to the proxy access provisions of our amended and restated by-laws must be received by the company’s corporate secretary by no earlier than April 28, 2026 and no later than May 28, 2026 (i.e., no earlier than

the 150th day and no later than the 120th day prior to the first anniversary of the date our definitive proxy statement was first released to stockholders in connection with the preceding year’s annual meeting of stockholders), unless the date of our 2026 Annual Meeting of Stockholders occurs more than 30 days before or 60 days after the first anniversary of the 2025 Annual Meeting of Stockholders. In that case, our amended and restated by-laws provide that we must receive the notice no earlier than the 180th day prior to the date of the 2026 Annual Meeting of Stockholders and no later than the 90th day prior to the date of the 2026 Annual Meeting of Stockholders or the tenth day following the day on which we first make a public announcement of the date of the 2026 Annual Meeting of Stockholders, whichever is later.

Stockholder’s Notice

To be in proper form, a stockholder’s notice must also include the specified information and comply with other requirements described in our amended and restated bylaws. Stockholders wishing to submit recommendations for director candidates to the board may send each candidate’s name and other relevant information for the nominating/corporate governance committee’s consideration in care of the company’s corporate secretary at our principal executive offices. Our nominating/ corporate governance committee is responsible for reviewing the qualifications of any such person submitted to be considered as a member of the board by any stockholder or otherwise and will consider and evaluate nominees proposed by stockholders in the same manner as a nominee recommended by another board member, management, search firm, or any other source. Nominations pursuant to advance notice should be in accordance with

the informational and other requirements described under Section 2.04 of the company’s amended and restated by-laws. Nominations pursuant to proxy access should be in accordance with the informational and other requirements described under Sections 2.04 and 2.05 of the company’s amended and restated by-laws.

Appendix A

Reconciliation of GAAP and Non-GAAP Information

Refer to the table below for a reconciliation from net earnings to adjusted EBIT for fiscal years 2025 and 2024. Our adjusted EBIT measure excludes the impact of taxes, certain interest expense and interest income, gain on sale of assets, transformation initiatives, legal settlements, and optimization initiatives. 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 below 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.” In addition to the table below, our Annual Cash Bonus Plan Results (as reflected on page 43 of our CD&A) exclude the impact of foreign currency fluctuations in excess of the fluctuations assumed in the target.

Refer to the table below for a reconciliation from net earnings to adjusted net earnings (income) for fiscal years 2025, 2024 and 2023. Our adjusted net earnings (income) measure excludes pre-tax and tax impacts of gain on sale of assets, transformation initiatives, legal settlements, and optimization initiatives. In addition to the table below, our PSU Program Results for adjusted net income growth (as reflected on page 44 of our CD&A) exclude the impacts of foreign currency fluctuations in excess of the fluctuations assumed in the target and the first-year impact of business acquisitions.

Reconciliation of GAAP and Non-GAAP Information

(a) | The charges in fiscal 2024 include consulting costs relating to our company-wide transformation initiatives.
(b) | In fiscal 2024, this represents reserve reversal of a legal matter from fiscal 2023.
(c) | In fiscal 2025, there were $23.9 million of severance charges related to broad-based, company-wide initiatives, including efforts to align resources with respect to our new global HCM products, offset by a $4.6 million partial reversal of the workforce optimization initiative from fiscal 2024. Severance charges have been taken in the past and not included as an adjustment to get to adjusted results. Unlike severance charges in prior periods, these specific charges relate to broad-based, company-wide initiatives.
(d) | The income tax (benefit)/provision was calculated based on the marginal tax rate in effect for the year ended June 30, 2025. For prior periods, the income tax benefit/(provision) was calculated based on the marginal tax rate in effect during the period of adjustment.

Refer to the table below for a reconciliation from consolidated revenue to revenue excluding zero-margin benefits pass-throughs (“ex-ZMPT”) for fiscal years 2025, 2024 and 2023. Our revenue ex-ZMPT measure is a consolidated revenue growth measure that excludes the impact of zero-margin benefits pass-throughs. In addition to the table below, our PSU Program Results for revenue ex-ZMPT growth (as reflected on page 44 of our CD&A) exclude the impacts of foreign currency fluctuations in excess of the fluctuations assumed in the target and the first-year impact of business acquisitions.

|  | Twelve Months Ended June 30,
(amounts in millions USD) |  | 2025 |  | 2024 |  | 2023
Total ADP revenues |  | $ | 20,560.9 |  | $ | 19,202.6 |  | $ | 18,012.2
Less: PEO zero-margin benefits pass-throughs |  |  | 4,289.0 |  |  | 3,975.9 |  |  | 3,800.9
Total ADP revenues excluding zero-margin benefits pass-throughs |  | $ | 16,271.9 |  | $ | 15,226.7 |  | $ | 14,211.3

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.
