The Board of Directors (the “Board”) of DuPont de Nemours, Inc. (the “Company” or “DuPont”) has set the close of business on March 29, 2023 as the record date for determining stockholders who are entitled to receive notice of the Annual Meeting and to vote.

As permitted by U.S. Securities and Exchange Commission (the “SEC”) rules, proxy materials were made available via the internet.

Cautionary Statement Regarding Forward Looking Statements

Certain statements within this proxy statement may constitute “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In this context, forward-looking statements often address expected future business and financial performance and financial condition, and often contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “see,” “will,” “would,” “target,” and similar expressions and variations or negatives of these words. Forward-looking statements address matters that are, to varying degrees, uncertain and subject to risks, uncertainties and assumptions, many of which that are beyond DuPont’s control, that could cause actual results to differ materially from those expressed in any forward-looking statements. Forward-looking statements are not guarantees of future results. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made, and should consider the uncertainties and risks discussed in our 2022 Annual Report on Form 10-K and subsequent filings with the U.S. Securities and Exchange Commission. DuPont assumes no obligation to publicly provide revisions or updates to any forward-looking statements whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws.

Corporate Governance Best Practices

As part of DuPont’s commitment to high ethical standards, the Board follows sound governance practices. These practices, which are summarized below, are described in more detail beginning on page 4 of this Proxy Statement.

Executive Compensation

We successfully navigated a challenging 2022 despite significant inflation, global supply chain constraints, geopolitical tensions, dynamic global currencies and an ongoing global pandemic. During 2022, we also completed key steps to further transform our portfolio and advance our strategy as a premier multi-industrial company. The 2022 compensation of our executive officers appropriately reflects and rewards their significant contributions to our performance in a year that presented unique challenges for our senior leadership team to manage.

Executive Compensation Governance Practices

Compensation of the executive officers of the Company, including that of the named executive officers, is overseen by the People and Compensation Committee (or, in the case of the Executive Chairman and Chief Executive Officer, by the People and Compensation Committee and the independent members of the Board). The Board and the People and Compensation Committee were assisted in performance of their oversight duties by an independent compensation consultant.

The following summarizes key governance elements related to the executive compensation programs in which our executive officers participate:

What We Do

What We Don’t Do

Maintain a pay mix that is heavily performance-based

Provide single-trigger change in control agreements or excise tax gross ups

Actively engage with stockholders

Grant options below market value, extend original option terms, reprice, reload or exchange underwater options without stockholder approval

Align executive compensation outcomes with company and individual performance

Annually assess peer group composition and competitive compensation practices

Permit hedging or pledging of the Company’s securities

Liberal share counting

Seek annual stockholder advisory approval of executive compensation

Maintain strong stock ownership requirements of six times base salary for the CEO and three times base salary for the other executive officers

Guaranteed annual salary increases or bonuses

Provide minimum payouts under the Long Term Incentive Plan

Conduct an annual executive talent review and discussion on succession planning

Provide uncapped short-and long-term incentive payouts

Excessive perks

Maintain an incentive clawback policy covering both cash and equity

Review executive compensation statements (“tally sheets”)

Conduct annual compensation risk assessments

Voting, Question and

Attendance Procedures

In this Proxy Statement, you will find information on the Board, the candidates for election to the Board, and three other items to be voted upon at the Annual Meeting and any adjournment or postponement of the Annual Meeting. The background information in this Proxy Statement has been supplied to you at the request of the Board to help you decide how to vote and to provide information on the Company’s corporate governance and compensation practices. This Proxy Statement is first being distributed to stockholders on or about April 6, 2023.

Vote Your Shares in Advance

You may vote your shares by internet, telephone or signing and returning the enclosed proxy or other voting instruction form. Your shares will be voted only if the proxy or voting instruction form is properly executed and received by the independent Inspector of Election prior to the Annual Meeting. Except as provided below with respect to shares held in employee savings plans, if no specific instructions are given by you when you execute your voting instruction form, as explained on the form, your shares will be voted as recommended by the Board.

You may revoke your proxy or voting instructions at any time before their use at the Annual Meeting by sending a written revocation, by submitting another proxy or voting form on a later date, or by voting virtually at the Annual Meeting. No matter which voting method you choose, however, you should not vote any single account more than once unless you wish to change your vote. Be sure to submit votes for each separate account in which you hold DuPont common stock.

Confidential Voting

The Company maintains vote confidentiality. Proxies and ballots of all stockholders are kept confidential from the Company’s management and Board unless disclosure is required by law and in other limited circumstances. The policy further provides that employees may confidentially vote their shares of Company stock held by employee savings plans and requires the appointment of an independent tabulator and Inspector of Election for the Annual Meeting.

Dividend Reinvestment Plan Shares and Employee Savings Plan Shares

If you are enrolled in the direct stock purchase and dividend reinvestment plan administered by Computershare Trust Company, N.A. (the “Computershare CIP”), the DuPont common stock owned on the record date by you directly in registered form, plus all shares of common stock held for you in the Computershare CIP, will appear together on a single proxy voting form. If no instructions are provided by you on an executed proxy voting form, your Computershare CIP shares will be voted as recommended by the Board.

Participants in various employee savings plans will receive a voting instruction form. Your executed form will provide voting instructions to the respective plan trustee. If no instructions are provided, the plan trustees and/or administrators for the relevant employee savings plan will vote the shares according to the provisions of the relevant employee savings plan. To allow sufficient time for voting, your voting instructions must be received by 11:59 P.M. Eastern Daylight Time on May 19, 2023. You may not vote your shares held in an employee savings plan virtually at the Annual Meeting.

DuPont Shares Outstanding and Quorum

At the close of business on the record date, March 29, 2023, there were 459,016,106 shares of DuPont common stock outstanding and entitled to vote. Each share of common stock is entitled to one vote. The holders of a majority of the issued and outstanding shares of common stock entitled to vote that are present in person or represented by proxy constitute a quorum for the transaction of business at the Annual Meeting.

For Agenda Item 1: Election of Directors, each nominee must receive more FOR votes than AGAINST votes in order to be elected. For Agenda Items 2 through 4, each such item must receive more FOR votes than AGAINST votes in order to be approved. Abstentions and broker non-votes will be included in determining the presence of a quorum at the Annual Meeting but will not be counted or have an effect on the outcome of any matter.

Broker non-votes occur when a person holding shares through a bank or broker, meaning that their shares are held in a nominee name or beneficially through such bank or broker, does not provide instructions as to how to vote their shares and the bank or broker is not permitted to exercise voting discretion. Under New York Stock Exchange (“NYSE”) rules, your bank or broker may vote shares held in beneficial name only on Agenda Item 3: Ratification of the Appointment of the Independent Registered Public Accounting Firm, without instruction from you, but may not vote on any other matter to be voted on at the Annual Meeting.

Proxy Solicitation on Behalf of the Board

The Board is soliciting proxies to provide an opportunity for all stockholders to vote, whether or not the stockholders are able to attend the Annual Meeting or an adjournment or postponement thereof. Directors, officers and employees may solicit proxies on behalf of the Board in person, by mail, by telephone or by electronic communication. The proxy representatives of the Board will not be specially compensated for their services in this regard.

DuPont has retained Innisfree M&A Incorporated to aid in the solicitation of stockholders (primarily brokers, banks and other institutional investors) for an estimated fee of $25,000, plus reasonable expenses. Arrangements have been made with brokerage houses, nominees and other custodians and fiduciaries to send materials to their principals, and their reasonable expenses will be reimbursed by DuPont on request. The cost of solicitation will be borne by DuPont.

Participating in the Annual Meeting

The Annual Meeting will be online and a completely virtual meeting of stockholders. We cordially invite all stockholders to participate in the Annual Meeting. To participate in the Annual Meeting, you will need the 16-digit control number included on your notice of Internet availability of the proxy materials, on your proxy card, or on the voting instructions that accompanied your proxy materials.

Other Matters

The Board does not intend to present any business at the Annual Meeting that is not described in this Proxy Statement. The enclosed proxy or other voting instruction form confers upon the designated persons the discretion to vote the shares represented in accordance with their best judgment. Such discretionary authority extends to any other properly presented matter. The Board is not aware of any other matter that may properly be presented for action at the Annual Meeting.

Corporate Governance

Strong corporate governance is an integral part of DuPont’s core values. Within this section, you will find information about the Board and its governance structure and processes.

DuPont Board Corporate Governance Guidelines

The Corporate Governance Guidelines form an important framework for the Board’s corporate governance practices and assist the Board in carrying out its responsibilities. The Board reviews these guidelines periodically to consider the need for amendments or enhancements. Among other things, these guidelines delineate the Board’s responsibilities, leadership structure, independence, qualifications, election, annual self-evaluation, and access to management and advisors.

We invite you to visit the Company’s website at https://www.investors.dupont.com/investors/dupont-investors/corporate-governance to review the following governance documents:

Director Independence

The Board has assessed the independence of each director who is currently on the Board or who served on the Board during the last fiscal year in accordance with the standards of independence of the NYSE rules and as described in the Corporate Governance Guidelines. Based upon these standards, the Board has determined that all of the directors who are currently on the Board or who served on the Board during the last fiscal year other than Mr. Breen are independent. The current independent directors constitute a “substantial majority” of the Board, consistent with our Corporate Governance Guidelines. In addition, the Board has determined that each of the nominees for director other than Mr. Breen is independent. The Nomination and Governance Committee, as well as the Board, annually reviews relationships that directors may have with the Company and members of management to make a determination as to whether there are any material relationships that would preclude a director from being independent.

All members of the Audit Committee, People and Compensation Committee, Nomination and Governance Committee, and Environment, Health, Safety and Sustainability Committee are independent directors under the Corporate Governance Guidelines and applicable regulatory and listing standards.

Board Leadership Structure

The Board is responsible for broad corporate policy and overall performance of the Company through oversight of management and stewardship of the Company. Among other duties, the Board appoints the Company’s officers, assigns to them responsibility for management of the Company’s operations, and reviews their performance.

Our governing documents provide the Board with the flexibility to determine the optimal leadership structure for the Company, including, when appropriate, separating the positions of Chair of the Board and Chief Executive Officer (“CEO”). We believe that it is important for the Board to determine, on a case-by-case basis, the most effective leadership structure for us. We believe that the Company and its stockholders benefit from this flexibility, and that the directors are best positioned to lead this evaluation given their knowledge of our leadership team, strategic goals, opportunities, and challenges.

The Board has determined that, at the present time, stockholders and the Board are best served by having Mr. Breen serve as the Executive Chairman of the Board and CEO. This is due, in part, to Mr. Breen’s role in orchestrating the strategic transformation of our Company, including through the DWDP Merger and subsequent separations of Dow and Corteva into independent public companies, the separation and sale of our N&B business to IFF, the separation and sale of a substantial portion of M&M to Celanese, as well as our acquisition of Laird Performance Materials. Mr. Breen is a proven leader with significant prior experience as a CEO and board member at Tyco International, plc and General Instrument Corporation and currently as lead independent director at Comcast Corporation. The Company has greatly benefitted from his strong leadership.

Our Corporate Governance Guidelines provide that if the Chair is not an independent director, as is the case with Mr. Breen, another director will be appointed by the independent directors to serve as independent Lead Director. Our independent directors have appointed Mr. Cutler to the role of Lead Director. Mr. Cutler has extensive leadership and corporate governance experience having previously served as the Chairman and CEO of Eaton Corporation, as well as a member of the Executive Committee of the Business Roundtable. In addition, Mr. Cutler currently serves as the independent Lead Director at KeyCorp. As Lead Director, Mr. Cutler’s responsibilities include:

Committees

Committees perform many important functions. The responsibilities of each Committee are stated in their respective Committee charters which are available at https://www.investors.dupont.com/investors/dupont-investors/corporate-governance. The Board, upon the recommendation of the Nomination and Governance Committee, elects members to each Committee and has the authority to change Committee chairs, memberships and the responsibilities of any Committee as set forth in the Bylaws.

The Board currently has four Committees: (i) Audit Committee; (ii) Nomination and Governance Committee; (iii) People and Compensation Committee; and (iv) Environment, Health, Safety and Sustainability Committee. All members of each of the four standing Committees of the Board are independent under the Company’s Corporate Governance Guidelines and applicable regulatory and listing standards.

A brief description of the responsibilities of the Committees are as follows:

Committees

ESG Oversight

The Board of Directors is responsible for overseeing the Company’s strategic direction, including the integration of environmental, social and governance (“ESG”) risks and opportunities into the Company’s strategy. Certain ESG oversight responsibilities are aligned with the most appropriate Committee as reflected in the table below. In addition, the chairs of each of the four standing Board Committees typically meet annually to discuss ESG risks impacting the Company’s strategy and to gain alignment on Board risk oversight in this area.

Committee Membership

The following chart shows Committee membership as of the date of this Proxy Statement. All directors listed in the table below other than Mr. Breen are independent.

CH = Chair

Board’s Role in the Oversight of Risk Management

The Board is responsible for overseeing the overall risk management process for the Company. Risk management is considered a strategic activity within the Company under the responsibility of executive management while the Committees and the Board as a whole participate in the oversight of the process. Specifically, the Board as a whole has responsibility for overseeing the strategic planning process and reviewing and monitoring management’s execution of the corporate and business plan. The Board is also responsible for overseeing risks associated with operational resiliency, cybersecurity, ESG, anti-corruption and fraud, geopolitical matters, innovation and mergers and acquisitions. Each Committee is responsible for oversight of specific risk areas relevant to their respective charters.

The Board, acting through its committee structure, is responsible for overseeing that management implements and follows this risk management process and for coordinating the outcome of reviews by Committees in their respective risk areas.

Although each Committee is responsible for overseeing the management of certain risks as described above, the full Board is regularly informed by the Committees about these risks. This enables the Board and the Committees to coordinate risk oversight and the

relationships among the various risks faced by the Company. For example, our Board is responsible for oversight of cybersecurity risk and receives reports from our Chief Information Officer and our Chief Information Security Officer at least once per year. In addition, our Audit Committee receives periodic reports from our Chief Information Officer and our Chief Information Security Officer in connection with its oversight over our internal control over financial reporting. The impact of cybersecurity on our internal control over financial reporting is also discussed with the full Board.

Succession Planning

The Board believes that one of its primary responsibilities is to oversee the development and retention of senior talent and to ensure that an appropriate succession plan is in place for the Chief Executive Officer and other members of senior management. The People and Compensation Committee, together with the Chief Executive Officer and the Chief Human Resources Officer, regularly reviews senior management talent, including readiness to take on additional leadership roles and developmental opportunities needed to prepare senior leaders for greater responsibilities. In addition, the People and Compensation Committee regularly discusses recommendations and evaluations from the Chief Executive Officer and the Chief Human Resources Officer as to potential successors to fill senior positions. The Chief Executive Officer and the Chief Human Resources Officer also provide a regular review to the People and Compensation Committee and the Board assessing the members of the executive leadership team and his or her potential to succeed the Chief Executive Officer. This review includes a discussion about development plans for senior leaders to help prepare them for future succession and contingency plans in the event the Chief Executive Officer is unable to serve for any reason (including death or disability). While the People and Compensation Committee has the primary responsibility to develop succession plans for the Chief Executive Officer position, it regularly reports to the Board and these matters are discussed and decisions are made at the Board level.

Stockholder Engagement

Throughout the year, we continued extensive outreach to stockholders. Through this outreach, the management team updated investors on a range of topics including our overall business strategy, current business conditions, corporate citizenship and sustainability, corporate governance practices and executive compensation, as well as gained an understanding of the perspectives and concerns of each investor.

The Board and management team carefully consider the feedback from these meetings, as well as stockholder support, when reviewing the business, corporate governance and executive compensation profiles of the Company and public disclosures made by the Company.

Communications with the Board and Directors

Stockholders and other parties interested in communicating directly with the Board, the Executive Chairman, the independent Lead Director or other independent directors, may do so by writing in care of the Office of the Corporate Secretary, 974 Centre Road, CRP Building 730, Wilmington, DE 19805. Pursuant to our Corporate Governance Guidelines, our Lead Director is available for consultation and direct communication if requested by major stockholders.

The Board’s independent directors have approved procedures for handling correspondence received by the Company and addressed to the Board, the Executive Chairman, the Lead Director or other outside directors. Communications will be distributed to any or all directors as appropriate depending upon the individual communication. However, the directors have requested that communications that do not directly relate to their duties and responsibilities as directors of the Company be excluded from distribution and deleted from email that they access directly. Such excluded items include “spam”; advertisements; mass mailings; form letters and email campaigns that involve unduly large numbers of similar communications; solicitations for goods, services, employment or contributions; surveys; and individual product inquiries or complaints. Additionally, communications that appear to be unduly hostile, intimidating, threatening, illegal or similarly inappropriate will also be screened for omission by the Office of the Corporate Secretary. Any omitted or deleted communication will be made available to any director upon such director’s request. Concerns relating to accounting, internal controls, auditing or ethical matters are brought to the attention of the internal audit function and handled in accordance with procedures established by the Audit Committee or the Nomination and Governance Committee, as applicable, with respect to such matters.

Board, Committees and Annual Meeting Attendance

During 2022, DuPont held 10 Board meetings and 25 Committee meetings. All of the incumbent directors attended more than 75% of the sum of the total number of Board meetings and the total number of meetings of the Committees on which the director served during the past year. All directors are encouraged to attend the Annual Meetings of Stockholders, and in 2022, all 12 of the directors nominated for election attended the Annual Meeting of Stockholders.

Executive Sessions of Directors

The non-employee directors meet in executive session in connection with each regularly scheduled meeting of the Board, and at other times as they may determine appropriate. During 2022, there were six executive sessions of the Board chaired by the Lead Director for the Board. The Committees typically meet in executive session at every meeting.

Director Qualifications and Diversity

Skills and Experience. The Nomination and Governance Committee has adopted guidelines to be used in evaluating candidates for Board membership in order to ensure a diverse and highly qualified Board. Directors are selected for their integrity and character; sound, independent judgment; breadth of experience, insight and knowledge; and business acumen. Leadership skills, scientific or technology expertise, familiarity with issues affecting global businesses in diverse industries, prior government service, diversity, time availability in light of other commitments, dedication and conflicts of interest are among the relevant criteria, which will vary depending on the needs of the Board.

Commitment to Diversity. Guidelines for director qualifications are included in the Corporate Governance Guidelines. The guidelines for director qualifications provide that a commitment to diversity is a consideration in the identification and nomination of director candidates, and that candidates are evaluated to provide for a diverse and highly qualified Board. Accordingly, the Nomination and Governance Committee includes, and has any search firm that it engages include, women and minority candidates in the pool from which the Committee selects director candidates. The Nomination and Governance Committee and the full Board implement and assess the effectiveness of these guidelines and the commitment to diversity by referring to these guidelines in the review and discussion of Board candidates when assessing the composition of the Board.

Limitations on Outside Board Service. Our Corporate Governance Guidelines limit the number of other public company boards on which a director may serve. No director who is an executive officer of a public company may serve as a director of the Company if he or she serves on more than a total of three public company boards, including the Board and the board of the company with which the director is employed. If a director is not an executive officer of a public company, he or she may serve on a maximum of four public company boards, including the Board. Directors are required to advise the Executive Chairman in advance of serving on another company’s board.

Director Nominee Skills and Diversity Matrix

As part of the nominee selection process for the Annual Meeting, the Nomination and Governance Committee reviewed the diversity of the Board, including the knowledge, skills and expertise and the demographic information set forth below. The Nomination and Governance Committee also reviewed the time commitments of each director and the results of the annual Board and individual director evaluations. Based upon the review of the Nomination and Governance Committee, it believes that the overall mix of the backgrounds of the nominees for election at the Annual Meeting provides for a diverse and highly qualified Board.
