A MESSAGE FROM THE CHAIR, PRESIDENT AND CHIEF EXECUTIVE OFFICER

Dear fellow stockholders,

I am happy to report the Nucor team delivered another strong financial performance in 2023, our third-most profitable year in Company history. For the year, Nucor generated $4.52 billion in net earnings, or $18.00 per diluted share. This represents a 23% return on average stockholders’ equity, marking our third consecutive year above 20%. In keeping with our goal of becoming the world’s safest steel company, we improved our safety performance for a fifth consecutive year, as measured by our injury and illness rate.

We achieved these results as we ramped up new operations, broke ground on growth projects and integrated recent acquisitions into the Nucor family.

We also advanced our strategy on climate change:

Our efforts have not gone unnoticed, with recognition from Fortune Magazine and Barron’s as displayed on the following page. While we are certainly proud of these awards, our initiatives in workplace safety and sustainability are far from complete. We know that continued improvement in both of these areas is essential to our long-term success.

Achieving our 2050 net-zero emission target depends on the scalability of emerging technologies in cleaner forms of power generation and iron making. We are not sitting idle and waiting for others to do the heavy lifting. Instead, we are actively investigating solutions and selectively investing our financial and human capital where we see the best application for Nucor. On the following page, we outline several sustainability initiatives Nucor is pursuing, which are aligned with our “Made for Good” campaign.

“Made for Good” is an important aspect of our GHG reduction strategy. It helps recognize Nucor’s leadership role in sustainable steel production and our ability to help customers achieve their own sustainability goals. We believe that the more customers value the low embodied carbon and circular nature of Nucor’s manufacturing process, the faster we can move toward a net-zero future.

I am excited about our recent performance on earnings, safety and sustainability, and we are committed to achieving even better results as we move forward.

On behalf of the Board of Directors and all Nucor teammates, thank you for your investment in our Company. We appreciate the trust you place in us. We ask for your continued support at this year’s annual meeting, so we can continue to deliver the results you expect and deserve as a Nucor stockholder.

Sincerely,

Leon J. Topalian

Chair, President and Chief Executive Officer

GENERAL INFORMATION

The Board of Directors (the “Board of Directors” or the “Board”) of Nucor Corporation (“Nucor,” the “Company,” “we,” “us” or “our”) is soliciting your proxy for use at the 2024 annual meeting of stockholders (the “Annual Meeting”) to be held at 9:00 a.m., Eastern Time, on Thursday, May 9, 2024. The Annual Meeting will be a virtual meeting, conducted exclusively via live audio webcast at www.virtualshareholdermeeting.com/NUE2024.

To participate in the Annual Meeting via live audio webcast, you will need the 16-digit control number, which can be found on the proxy card, voting instruction form or notice provided or the instructions that you receive by e-mail. If you hold your shares in the name of a broker, bank, trustee or other nominee, you may contact your broker, bank, trustee or other nominee for assistance with your 16-digit control number. If you encounter any difficulties accessing the live audio webcast of the Annual Meeting during the online check-in process or during the meeting itself, including any difficulties with your 16-digit control number, please call the technical support number available on the virtual meeting site, www.virtualshareholdermeeting.com/NUE2024.

Nucor has designed the format of the Annual Meeting to ensure that stockholders are afforded the same rights and opportunities to participate as they would have at an in-person meeting, using online tools to ensure stockholder access and participation. Specifically, stockholders participating in the Annual Meeting will be able to vote their shares electronically and to submit questions during the meeting using the directions on the virtual meeting site, www.virtualshareholdermeeting.com/NUE2024, that day. Individuals interested in attending the Annual Meeting and who do not have a control number may register as a guest on the virtual meeting site but will not be able to vote or to submit questions during the meeting. The Annual Meeting will begin promptly at 9:00 a.m., Eastern Time. Please allow ample time for the online check-in process.

Delivery of Proxy Materials

The Securities and Exchange Commission rules and regulations (the “SEC rules”) allow companies to choose the method for delivery of proxy materials to stockholders. For most stockholders, we have elected to mail a notice regarding the availability of proxy materials on the Internet, rather than sending a full set of these materials in the mail. The notice, or a full set of the proxy materials (including the Proxy Statement and form of proxy), as applicable, was sent to stockholders beginning March 22, 2024, and the proxy materials were posted on the investor relations portion of the Company’s website, www.nucor.com/investors, and on the website referenced in the notice on the same day. Utilizing this method of proxy delivery expedites receipt of proxy materials by the Company’s stockholders and lowers the cost of the Annual Meeting. If you would like to receive a paper or e-mail copy of the proxy materials, you should follow the instructions in the notice for requesting a copy. The information on our website or linked to or from our website is not incorporated by reference into, and does not constitute a part of, this Proxy Statement.

Shares Entitled to Vote; Quorum

The record date for the Annual Meeting is March 11, 2024. Only holders of record of Nucor common stock as of the close of business on that date will be entitled to vote at the Annual Meeting. As of the close of business on the record date, 239,979,947 shares of Nucor common stock were issued and outstanding. The presence, in person or by proxy, of the holders of a majority of the shares of Nucor common stock issued and outstanding and entitled to vote at the Annual Meeting is necessary to constitute a quorum for the transaction of business at the meeting. Virtual attendance at the Annual Meeting constitutes presence in person for purposes of establishing a quorum at the meeting. Your shares are counted as being present if you participate in the Annual Meeting via live audio webcast and cast your vote online during the meeting prior to the closing of the polls by visiting www.virtualshareholdermeeting.com/NUE2024, or if you vote by proxy, via the Internet, by telephone or by returning a properly executed and dated proxy card or voting instruction form by mail.

Voting Rights and Procedures

Each share of Nucor common stock outstanding as of the close of business on the record date is entitled to one vote except with respect to the election of directors. With respect to the election of directors, each share of Nucor common stock is entitled to cumulative voting rights, which means that when voting for director nominees each share is entitled to a number of votes equal to the number of nominees for election as directors. Accordingly, when voting for director nominees, all of the votes to which a share of Nucor common stock is entitled may be voted in favor of one nominee or may be distributed among the nominees. The proxy holders will have the discretionary authority to cumulate votes in the election of directors.

 2024 Proxy Statement 3

GENERAL INFORMATION

Stockholders of record who wish to cumulate their votes must submit a proxy card and make an explicit statement of their intent to do so, by so indicating in writing on their proxy card. If a person who is the beneficial owner of shares held in street name wishes to cumulate his or her votes, the stockholder will need to contact the broker, bank, trustee or other nominee who is the record owner of the shares.

Voting Requirement to Approve Each of the Proposals

The following sets forth the voting requirement to approve each of the proposals:

Proposal 1, Election of Directors. Directors shall be elected by a plurality of the votes cast (meaning that the eight director nominees who receive the highest number of votes cast “for” their election will be elected as directors), subject to a Corporate Governance Principle adopted by the Board of Directors as described below under the heading “‘Withhold’ Votes, Abstentions and Broker Non-Votes” and under “Proposal 1: Election of Directors.”

Proposal 2, Ratification of the Appointment of Independent Registered Public Accounting Firm. Ratification of the appointment of PricewaterhouseCoopers LLP to serve as Nucor’s independent registered public accounting firm for 2024 requires the affirmative vote of the holders of a majority of shares present in person or represented by proxy and entitled to vote on the proposal (meaning that of the shares represented at the Annual Meeting and entitled to vote, a majority of them must be voted “for” the proposal for it to be approved).

Proposal 3, Advisory Vote to Approve our Named Executive Officer Compensation. Advisory approval of Nucor’s named executive officer compensation in 2023 requires the affirmative vote of the holders of a majority of shares present in person or represented by proxy and entitled to vote on the proposal (meaning that of the shares represented at the Annual Meeting and entitled to vote, a majority of them must be voted “for” the proposal for it to be approved on an advisory basis).

Other Items. Approval of any other matters requires the affirmative vote of the holders of a majority of shares present in person or represented by proxy and entitled to vote on the item (meaning that of the shares represented at the Annual Meeting and entitled to vote, a majority of them must be voted “for” the item for it to be approved).

Methods of Voting

Electronically During the Annual Meeting. Stockholders of record and beneficial owners of shares held in street name may participate in the Annual Meeting via live audio webcast and cast their vote online during the meeting prior to the closing of the polls by visiting www.virtualshareholdermeeting.com/NUE2024; provided, however, if you hold your shares in the name of a broker, bank, trustee or other nominee, you may contact your broker, bank, trustee or other nominee for assistance with your 16-digit control number.

Via the Internet or by Telephone. Stockholders of record may vote by proxy, via the Internet or by telephone, by following the instructions included in the proxy card or notice provided or the instructions that they receive by e-mail. If you are a beneficial owner of shares held in street name, your ability to vote via the Internet or by telephone depends on the voting procedures of the broker, bank, trustee or other nominee who is the record owner of your shares. Please follow the instructions included in the voting instruction form or notice provided to you by the stockholder of record.

By Mail. Stockholders of record and beneficial owners of shares held in street name may vote by proxy by completing, signing, dating and returning the proxy card or voting instruction form provided.

“Withhold” Votes, Abstentions and Broker Non-Votes

“Withhold” votes, abstentions and broker non-votes are counted as present or represented for purposes of determining the presence or absence of a quorum for the Annual Meeting. A broker non-vote occurs when a nominee holding shares in street name for a beneficial owner votes on one proposal but does not vote on another proposal because, with respect to such other proposal, the nominee does not have discretionary voting power and has not received voting instructions from the beneficial owner.

4   2024 Proxy Statement

GENERAL INFORMATION

Under the New York Stock Exchange rules (the “NYSE rules”), proposal 2, the ratification of the appointment of PricewaterhouseCoopers LLP to serve as Nucor’s independent registered public accounting firm for 2024, is considered a “routine” matter, which means that brokerage firms may vote in their discretion on this proposal on behalf of clients who have not furnished voting instructions. However, proposal 1, the election of directors, and proposal 3, the advisory vote on our named executive officer compensation, are both “non-routine” matters under the NYSE rules, which means that brokerage firms that have not received voting instructions from their clients on these matters may not vote on these proposals.

With respect to proposal 1, the election of directors, only “for” and “withhold” votes may be cast. Broker non-votes are not considered votes cast for the foregoing purpose and will therefore have no effect on the election of director nominees. “Withhold” votes will also generally have no effect on the election of director nominees. However, the Board of Directors has adopted a Corporate Governance Principle intended to give effect to “withhold” votes in uncontested director elections under certain circumstances. This Corporate Governance Principle, which is described in more detail in this Proxy Statement under “Proposal 1: Election of Directors,” requires, in an uncontested election, any nominee for director who is an incumbent director and receives a greater number of “withhold” votes from his or her election than votes “for” his or her election to promptly tender his or her resignation to Nucor’s Corporate Secretary following certification of the stockholder vote for consideration by the Board.

With respect to proposals 2 and 3, the ratification of the appointment of PricewaterhouseCoopers LLP to serve as Nucor’s independent registered public accounting firm for 2024 and the advisory vote on Nucor’s named executive officer compensation, respectively, you may vote “for” or “against” these proposals or you may “abstain” from voting on these proposals. Abstentions will be counted as votes present or represented and entitled to vote on these proposals and will therefore have the same effect as votes “against” these proposals. With respect to proposal 3, broker non-votes will not be considered entitled to vote on this proposal and will therefore have no effect on its outcome. As discussed above, because proposal 2, the ratification of the appointment of PricewaterhouseCoopers LLP to serve as Nucor’s independent registered public accounting firm for 2024, is considered a “routine” matter, we do not expect any broker non-votes with respect to this proposal.

Voting of Proxies

Each valid proxy received and not revoked before the Annual Meeting will be voted at the meeting. To be valid, a written proxy card must be properly executed and dated. Proxies voted via the Internet or by telephone must be properly completed pursuant to this solicitation. If you specify your vote regarding any matter presented at the Annual Meeting, your shares will be voted by one of the individuals named on the proxy card in accordance with your specification. If you do not specify your vote, your shares will be voted:

Revoking Your Proxy or Changing Your Vote

You may revoke your proxy or change your vote at any time before the vote is taken at the Annual Meeting. If you are a stockholder of record, you may revoke your proxy or change your vote by (i) submitting a written notice of revocation to Nucor’s Corporate Secretary at Nucor Corporation, 1915 Rexford Road, Charlotte, North Carolina 28211; (ii) delivering a proxy bearing a later date via the Internet, by telephone or by mail until the applicable deadline for each method specified in the accompanying proxy card or the notice; or (iii) participating in the Annual Meeting via live audio webcast and voting online during the meeting prior to the closing of the polls. Participation in the Annual Meeting will not cause your previously granted proxy to be revoked unless you vote online during the meeting prior to the closing of the polls. For all methods of voting, the last vote cast will supersede all previous votes. If you hold your shares in street name and you have instructed your broker, bank, trustee or other nominee to vote your shares, you may revoke or change your voting instructions by following the specific instructions provided to you by your broker, bank, trustee or other nominee.

 2024 Proxy Statement 5

PROPOSAL 1:

ELECTION OF DIRECTORS

The number of directors on Nucor’s Board of Directors is currently fixed at nine. Joseph D. Rupp is not standing for reelection at the Annual Meeting. Mr. Rupp has been a member of the Board since 2020, serving on the Audit, Compensation and Executive Development, and Governance and Nominating Committees during such time. Mr. Rupp has been an integral and valuable member of the Nucor team. Effective on the date of the Annual Meeting, the size of the Board will be reduced to eight members.

On the recommendation of the Governance and Nominating Committee, the Board of Directors has nominated the following eight persons for election as directors at the Annual Meeting: Norma B. Clayton; Patrick J. Dempsey; Nicholas C. Gangestad; Christopher J. Kearney; Laurette T. Koellner; Michael W. Lamach; Leon J. Topalian; and Nadja Y. West. If elected, each nominee will serve until his or her term expires at the 2025 annual meeting of stockholders or until his or her earlier death, resignation or removal.

All of the nominees are currently serving as directors and were elected to the Board of Directors at the 2023 annual meeting of stockholders except for Mr. Gangestad, who was appointed to the Board effective September 2023. Mr. Gangestad was initially identified to the Board as a potential director by a leadership advisory firm. Each director nominee has agreed to be named in this Proxy Statement and to serve if elected.

Shares represented by all proxies received by the Board of Directors and not marked to withhold authority to vote for the nominees will be voted for their election. The Board knows of no reason why any of the director nominees should be unable or unwilling to serve, but if that should be the case, proxies received will be voted for the election of such other persons, if any, as the Board may designate.

Majority Voting in Uncontested Director Elections. We have a majority vote standard in uncontested director elections in order to address “holdover” terms for any incumbent directors. Under our Corporate Governance Principles, in an uncontested director election, any nominee for director who is an incumbent director and receives a greater number of votes “withheld” from his or her election than votes “for” his or her election must promptly tender his or her resignation to the Corporate Secretary of the Company following certification of the stockholder vote for consideration by the Board of Directors. In such event, within 120 days following certification of the stockholder vote, the Board will decide, after taking into account the recommendation of the Governance and Nominating Committee (in each case excluding the nominee(s) in question), whether to accept the resignation. The Governance and Nominating Committee and the Board may each consider all factors it deems relevant in deciding whether to accept a director’s resignation. Nucor will promptly disclose the Board’s decision and the reasons therefor in a Form 8-K filing with the Securities and Exchange Commission (the “SEC”). The resignation policy set forth in the Company’s Corporate Governance Principles does not apply to contested elections.

Vote Recommendation

The Board of Directors recommends a vote “FOR” the election of each of the eight director nominees named in this proposal.

6   2024 Proxy Statement

INFORMATION CONCERNING EXPERIENCE, QUALIFICATIONS, ATTRIBUTES AND SKILLS OF THE NOMINEES

The Board of Directors consists of a diverse group of individuals that provide dedicated and effective oversight of the Company. All of our director nominees possess integrity, independent perspective, strong work ethic, strength of conviction, collaborative approach to engagement, inquisitiveness and the willingness to appropriately challenge management. In addition to these attributes, when evaluating potential Board members, the Board considers a wide range of experience, qualifications and skills, many of which are identified in the matrix below, that it believes contribute to a well-rounded perspective suitable to growing our Company and protecting the interests of our stockholders. While we look to each director nominee to be knowledgeable in the areas identified in the matrix, the areas do not comprise all of the diverse experience, qualifications and skills our director nominees possess and routinely contribute to our Company. In addition, the absence of a ✓ in the matrix does not mean that the director nominee does not possess that experience, qualification or skill; however, the mark indicates that the area is a particularly prominent experience, qualification or skill that the director nominee brings to the Board.

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

Board of Directors. Our business and affairs are managed under the direction of the Board of Directors. In exercising its fiduciary duties, the Board represents and acts on behalf of the Company’s stockholders. Our Bylaws provide that the Board consists of a number of directors to be fixed from time to time by a resolution of the Board. The Board of Directors currently has nine members, eight of whom are independent. If the director nominees are elected at the Annual Meeting, the Board will have eight members, seven of whom will be independent.

Corporate Governance Principles. The Board has adopted Corporate Governance Principles setting forth a framework for our corporate governance with respect to the role and composition of the Board and Nucor’s management, responsibilities of directors, director qualification standards (including working to ensure Board diversity), functioning of the Board and its committees, compensation of directors, and annual performance evaluations of the Board, its committees, individual directors, the Chair or Non-Executive Chair of the Board (as applicable), Lead Director (if applicable) and our Chief Executive Officer (or “CEO”).

Codes of Ethics. The Board has adopted a Code of Ethics for Senior Financial Professionals that applies to the Company’s CEO, Chief Financial Officer, Corporate Controller and other senior financial professionals and includes guidelines relating to the ethical handling of actual or apparent conflicts of interest, compliance with laws and accurate financial reporting. In addition, the Board has adopted Standards of Business Conduct and Ethics, which apply to all teammates, officers and directors of the Company. The Company intends to post any amendments to, or waivers from, either of these documents (to the extent required to be disclosed pursuant to Form 8-K) on the Company’s website at www.nucor.com/esg.

Documents Available. Certain of the Company’s corporate governance materials, including the charters for the Audit Committee, the Compensation and Executive Development Committee and the Governance and Nominating Committee, the Corporate Governance Principles, the Code of Ethics for Senior Financial Professionals, the Standards of Business Conduct and Ethics, and the Executive Officer Incentive Compensation Recovery Policy are available on the Company’s website at www.nucor.com/leadership or www.nucor.com/esg. The Company also makes available on its website at www.nucor.com/esg the Company’s Human Rights Policy and other supply chain documents, including a Supplier Code of Conduct, a policy on Combatting Trafficking in Persons and a policy on Eliminating Forced Labor from our Supply Chain, as well as a report on the Company’s Political Disclosures and Lobbying Oversight. In addition, the Company posts on its website at www.nucor.com/esg the Company’s Sustainability Accounting Standards Board Disclosure, the Company’s Financial Stability Board TCFD Report, the Company’s Safety Overview and the Company’s commitment to Inclusion, Equity and Diversity, including its EEO-1 Consolidated Employer Information Report. Any modifications to these documents will be reflected on the Company’s website.

Director Independence. The Board believes that a majority of its members are independent under the applicable NYSE rules and SEC rules. The NYSE rules provide that a director does not qualify as “independent” unless the board of directors affirmatively determines that the director has no material relationship with the company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company). The NYSE rules recommend that a board of directors consider all of the relevant facts and circumstances in determining the materiality of a director’s relationship with a company. The Board has adopted Categorical Standards for Determination of Director Independence (the “Categorical Standards”) to assist the Board in determining whether a particular relationship a director has with the Company is a material relationship that would impair the director’s independence. The Categorical Standards establish thresholds at which directors’ relationships with the Company are deemed to be not material and, therefore, shall not disqualify any director or director nominee from being considered “independent.” The Categorical Standards are included as an appendix to Nucor’s Corporate Governance Principles, which are available on the Company’s website at www.nucor.com/esg.

In February 2024, the Board, with the assistance of the Governance and Nominating Committee, conducted an evaluation of director independence based on the Categorical Standards, the NYSE rules and the SEC rules. The Board considered all relationships and transactions between each director (and his or her immediate family members and affiliates) and each of Nucor, its management and its independent registered public accounting firm, including, with respect to Mr. Gangestad, who serves as Senior Vice President and Chief Financial Officer of Rockwell Automation, Inc., that Nucor in the ordinary course of business purchased from Rockwell Automation goods and services in 2023 in an amount less than 0.5% of the consolidated gross revenues of Rockwell

14   2024 Proxy Statement

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

Automation. As a result of this evaluation, the Board determined those relationships that do exist or did exist within the last three years (except for Mr. Topalian’s in his capacity as Chair, President and CEO) all fall well below the thresholds in the Categorical Standards, the NYSE rules and the SEC rules. Consequently, the Board of Directors determined that General West and each of Messrs. Dempsey, Gangestad, Kearney and Lamach and each of Mses. Clayton and Koellner is an independent director, and Mr. Rupp (whose term on the Board will expire immediately before the Annual Meeting) was an independent director during the period that he served as a director, under the Categorical Standards, the NYSE rules and the SEC rules. The Board also determined that each member of the Audit Committee, the Compensation and Executive Development Committee and the Governance and Nominating Committee (see membership information below under “Board Committees”) is independent, including that each member of the Audit Committee is “independent” as that term is defined under Rule 10A-3(b)(1)(ii) under the Securities Exchange Act of 1934, as amended (the “1934 Act”).

Overboarding Policy. The Company’s Corporate Governance Principles provide that (i) in addition to service on the Board, directors may not serve on more than three public company boards and (ii) a director who is a CEO of a public company may serve on the board of that company and only one other public company board of directors.

The Governance and Nominating Committee annually evaluates each director’s prior service on and contributions to the Board, including consideration of each director’s public company leadership positions and other outside commitments prior to recommending a director or nominee for election to the Board. All of our directors are currently in compliance with our overboarding policy.

Director Retirement/Board Refreshment. The Company’s Corporate Governance Principles provide that the mandatory retirement date for a non-employee director is the annual meeting following the director’s 72^nd birthday. The Board believes the mandatory retirement age is an important aspect of its refreshment efforts, which also include adding new directors to the Board as appropriate (including five new independent directors added to the Board in the past five years) and annually assessing the Board and its committees in a robust evaluation process. However, in select circumstances, where the Board deems it in the best interest of the Company and its stockholders after balancing considerations including the composition of the Board, tenure of its members, director qualifications and contributions to the Company, and any extenuating circumstances, the Board might extend the mandatory retirement age.

Board Leadership Structure. Mr. Topalian currently serves in the combined positions of Chair of the Board and President and CEO. Mr. Kearney serves as Lead Director of the Company. The Company’s Corporate Governance Principles provide that whenever the Chair of the Board is a member of management, there will be a Lead Director who is appointed by the independent members of the Board and will serve at the pleasure of the Board.

After thorough consideration of a number of factors, including, among others, the execution of our Company’s strategic priorities, the complexity and environment of our business, Mr. Topalian’s knowledge of our industry and risks, the various capabilities and tenure of our directors, the highly independent composition of the Board, and the meaningful and extensive responsibilities of the independent Lead Director, the Board believes the combined positions of Chair of the Board and President and CEO continue to serve the best interests of the Company and its stockholders at this time. The Board has a high level of confidence in Mr. Topalian’s leadership and continued ability to work closely and transparently with our independent directors. Moreover, the Board believes that, in the role of Chair and President and CEO, Mr. Topalian is best positioned to be aware of key issues facing the Company, serve as a highly effective bridge between the Board and management, and communicate efficiently with our stockholders. The Board believes that the combined Chair and President and CEO role together with the strong and longstanding independent leadership provided by Mr. Kearney as our Lead Director and each of the three standing Board committees, which are chaired by and composed solely of independent directors, provides an appropriate balance between effective independent oversight and strong, consistent leadership to drive execution of our strategic priorities.

The Board has not adopted a formal policy regarding the need to combine or separate the offices of Chair of the Board and President and CEO. The Company previously separated the roles of Chair of the Board and President and CEO and, in the future, the Board may determine in certain circumstances that it is in the best interests of the

 2024 Proxy Statement 15

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

Company and our stockholders for different persons to hold such positions. The Board’s leadership structure is outlined in the Company’s Bylaws and Corporate Governance Principles, as described below:

Board Committees. The Board has three standing committees: the Audit Committee, the Compensation and Executive Development Committee and the Governance and Nominating Committee. Each of these committees acts pursuant to a written charter adopted by the Board. Committee members and committee chairs are appointed by the Board. The current members and chairs of these committees are identified in the table below:

16   2024 Proxy Statement

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

The following table provides information about the operation and key functions of these committees:

 2024 Proxy Statement 17

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

The Board has determined that Ms. Koellner is an “audit committee financial expert” within the meaning of the SEC rules and that she has accounting and related financial management expertise as determined by the Board in its business judgment. The Board has also determined that each member of the Audit Committee is financially literate as determined by the Board in its business judgment.

The Board may also establish other committees from time to time as it deems necessary.

Director Meetings. The Board held five meetings during 2023, including one joint meeting with the Governance and Nominating Committee. Each incumbent director attended, or participated by means of remote communication, in 75% or more of the aggregate number of meetings of the Board and committees of the Board on which such director served during 2023. Pursuant to the Corporate Governance Principles, the independent directors meet in executive session prior to or after each quarterly Board meeting and as necessary prior to or after other Board meetings. Mr. Kearney, as Lead Director, presided over all executive sessions in 2023.

Attendance at Annual Meetings of Stockholders. Directors are expected to attend the Company’s annual meeting of stockholders. All eight of the Company’s directors in office at the time, including all of the Company’s current directors who were then directors, participated in the Company’s 2023 annual meeting of stockholders, which was held virtually via live audio webcast.

Annual Evaluation of Directors and Committee Members. The Board evaluates the performance of each director, each committee of the Board, the Chair or Non-Executive Chair of the Board (as applicable), Lead Director (if applicable), the CEO and the Board as a whole on an annual basis. In connection with this annual self-evaluation, each director anonymously records his or her views on the performance of each director, each committee of the Board, the Chair or Non-Executive Chair of the Board (as applicable), Lead Director (if applicable), the CEO and the Board as a whole. The entire Board reviews the results of these reports and determines what, if any, actions should be taken in the upcoming year to improve its effectiveness and the effectiveness of each director, each committee of the Board, the Chair or Non-Executive Chair of the Board (as applicable), Lead Director (if applicable) and the CEO.

Board’s Role in Risk Oversight. The Board oversees the Company’s risk profile and management’s processes for assessing and managing risk, both as a whole Board, and through its committees. At least annually, the full Board reviews strategic risks and opportunities facing the Company. Among other areas, the

18   2024 Proxy Statement

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

Board is involved in overseeing risks related to the Company’s overall strategy, business results, capital structure, capital allocation and budgeting, and executive officer succession. Certain other important categories of risk are assigned to designated Board committees (which are composed solely of independent directors) that report back to the full Board.

The Audit Committee is specifically charged with the responsibility of meeting periodically with management, the Company’s General Counsel and outside counsel to discuss the Company’s major financial risk exposures, including, but not limited to, legal and environmental claims and liabilities, cybersecurity, risk management and other financial exposures, and the steps management has taken to monitor and control such exposures, including the Company’s risk assessment and risk management policies. The Company’s Corporate Controller annually conducts a risk assessment, which includes input from senior officers, and prepares for the Audit Committee’s review a report and a presentation identifying and evaluating the key risks facing the Company, how those risks interrelate, how they affect the Company and how management addresses those risks. After completing a review and analysis of the report and the presentation, the Audit Committee meets with management to provide its comments on the report and the presentation and to provide guidance on areas that the Audit Committee believes management and the Corporate Controller should consider in identifying and evaluating the risks facing the Company.

The Compensation and Executive Development Committee oversees Nucor’s executive compensation plans to ensure they do not incentivize excessive risk-taking by our senior officers. Although a significant portion of our executives’ compensation is performance-based, we believe our compensation plans are appropriately structured and do not pose a material risk to Nucor.

The Governance and Nominating Committee oversees issues that may create governance risks, such as Board composition and structure, director selection and director succession planning.

The Board believes that its leadership structure supports the Company’s governance approach to risk oversight. Mr. Topalian is involved directly in risk management as a member of the Company’s management team. As Chair of the Board, and together with the independent committee chairs in their respective areas, Mr. Topalian also maintains oversight roles at the board level. In addition, Mr. Kearney, as Lead Director, maintains the ability to set the agenda for and lead executive sessions of the non-employee directors without the attendance of management.

Compensation Consultant. The Compensation and Executive Development Committee has sole authority under its charter to retain compensation consultants and to approve such consultants’ fees and retention terms. The Compensation and Executive Development Committee has retained Pearl Meyer & Partners, LLC (“Pearl Meyer”) to act as its independent advisor and to provide it with advice and support on executive compensation issues. The Compensation and Executive Development Committee has reviewed and confirmed the independence of Pearl Meyer as the committee’s compensation consultant. Neither Pearl Meyer nor any of its affiliates provides any services to Nucor except for services related solely to executive officer and director compensation. Please see “Executive Officer Compensation – Compensation Discussion and Analysis – 2023 Executive Compensation in Detail – Determination of 2023 Compensation” on page 34 of this Proxy Statement for a description of Nucor’s process for the consideration and determination of executive compensation and Pearl Meyer’s role in such process.

No Hedging, Short Selling or Pledging. Nucor maintains a trading policy that prohibits any hedging or short selling (profiting if the market price decreases) of Nucor securities by any director, officer or general manager of Nucor or any other employee of the Company whose function and responsibilities provide access to material, non-public information about Nucor. The trading policy also prohibits such persons from pledging Nucor securities as collateral in a margin account with a broker-dealer.

Policy on Executive Officer Incentive Compensation Recoupment. Effective October 2, 2023, the Compensation and Executive Development Committee adopted the Executive Officer Incentive Compensation Recovery Policy (the “Clawback Policy”), intended to comply with the final clawback rules adopted by the SEC pursuant to Section 10D and Rule 10D-1 of the Exchange Act, and the related NYSE listing requirements (together, the “Final Clawback Rules”). The Clawback Policy, which supersedes the Company’s prior compensation recovery policy, requires the Company to recover reasonably promptly any erroneously awarded incentive-based

 2024 Proxy Statement 19

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

compensation received by current and former executive officers (as defined in the Clawback Policy) of the Company in the event that the Company is required to prepare an accounting restatement, in accordance with the Final Clawback Rules. The recovery of such compensation applies regardless of whether an executive officer engaged in misconduct or otherwise caused or contributed to the requirement of an accounting restatement. Under the Clawback Policy, the Company may recoup from current or former executive officers erroneously awarded incentive-based compensation received within a lookback period of the three completed fiscal years preceding the date on which the Company is required to prepare an accounting restatement. A copy of the policy is available on our website at www.nucor.com/esg.

Policy on Transactions with Related Persons. The Company has a written policy and procedures for the review and approval in advance of any transactions that could potentially be required to be reported under the SEC rules for disclosure of transactions with the Company’s directors and executive officers, business and other organizations with which its directors or executive officers are affiliated, members of their immediate families and other related persons. This policy is administered by the Governance and Nominating Committee of the Board of Directors. The policy includes certain categories of pre-approved transactions that are based upon exceptions to the SEC’s rules for disclosure of such transactions. For transactions that are not pre-approved, the Governance and Nominating Committee, in determining whether to approve a transaction with a related person or an organization with which a related person is affiliated, takes into account, among other things, (i) whether the transaction was undertaken in the ordinary course of business of the Company; (ii) the approximate dollar value of the transaction; (iii) the purpose, and potential benefits to the Company, of the transaction; and (iv) the related person’s interest in the transaction, including whether the related person or his or her immediate family member participated in the negotiation of the terms of the transaction or received any special benefits from the transaction.

Transactions with Related Persons. In 2023, Lauren Burnham, a melting and casting day supervisor at Nucor and the daughter of Douglas J. Jellison, an executive officer of Nucor, was paid compensation of approximately $254,000. Also in 2023, Thomas Burnham, a day supervisor at Nucor and the son-in-law of Mr. Jellison, was paid compensation of approximately $222,500. The foregoing transactions were approved under Nucor’s policy on transactions with related persons.

Director Nomination Process. The Governance and Nominating Committee has a process of identifying and evaluating potential nominees for election as members of the Board. The Governance and Nominating Committee has a policy that potential nominees will be evaluated no differently regardless of whether the nominees are recommended by a stockholder, a Board member or Nucor’s management. The Governance and Nominating Committee considers potential nominees from all of these sources, develops information from many sources concerning the potential nominees, evaluates the potential nominees as to the qualifications that the committee and the Board have established and in light of the current skill, background and experience of the Board’s members and the future, ongoing needs of the Company and makes a decision whether to recommend any potential nominee for consideration for election as a member of the Board. In the past, Nucor has engaged third-party search firms to assist the Governance and Nominating Committee in identifying and evaluating potential director nominees, and Nucor may do so again in the future.

The Governance and Nominating Committee is committed to ensuring that the Board is composed of individuals representing a diversity of thoughts, backgrounds, skills, experiences and expertise. Pursuant to the Company’s Corporate Governance Principles and the charter for the Governance and Nominating Committee, in evaluating potential nominees for election and reelection as members of the Board, the Governance and Nominating Committee considers persons representing a diversity of thoughts, backgrounds, skills, experiences and expertise and includes in each third-party search for new nominees, qualified candidates who reflect diverse backgrounds, including diversity of gender and race. In addition, the potential nominee must:

20   2024 Proxy Statement

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

The Governance and Nominating Committee also believes there are certain specific qualifications and skills that one or more members of the Board of Directors must possess. These include experience in manufacturing operations, financial knowledge and capital allocation expertise, CEO leadership experience, ability to oversee business development and drive overall growth, experience in talent development and succession planning, global business, sustainability matters, risk management and controls, public company governance and technology. For additional information, see page 7, “Information Concerning Experience, Qualifications, Attributes and Skills of the Nominees.”

The Governance and Nominating Committee assesses the Board’s effectiveness in balancing these considerations when reviewing the composition of the Board, and has determined that all of the nominees for election as directors at the Annual Meeting collectively possess the personal characteristics, level of commitment to the Company, tenure, diversity, skills and experience that align with the Company’s long-term strategy and that enable the Board to operate in an engaged and effective manner.

Recommending Directors. Stockholders may recommend a director nominee to be considered for Nucor’s 2025 annual meeting of stockholders by submitting the nominee’s name in accordance with provisions of the Company’s Bylaws, which require advance notice to the Company and certain other information. In general, under the Bylaws, the written notice must be delivered to, or mailed and received at, the Company’s principal executive offices not later than the close of business on the 120^th day before the first anniversary of the Annual Meeting nor earlier than the close of business on the 150^th day before the first anniversary of the Annual Meeting. As a result, notice of director nominees submitted by a stockholder pursuant to the provisions of Nucor’s Bylaws (other than proxy access director nominees) must be delivered, or mailed and received, not earlier than the close of business on December 10, 2024 and not later than the close of business on January 9, 2025. However, in the event that the date of the 2025 annual meeting of stockholders is more than 30 days before or more than 60 days after May 9, 2025, notice by the stockholder to be timely must be so delivered, or mailed and received, not earlier than the close of business on the 120^th day prior to the date of the 2025 annual meeting of stockholders and not later than the close of business on the later of the 90^th day prior to the date of such annual meeting or, if the first public announcement of the date of such annual meeting is less than 100 days prior to the date of such annual meeting, the 10^th day following the day on which public announcement of the date of such meeting is first made by the Company.

The notice must contain certain information about both the nominee and the stockholder submitting the nomination as set forth in Nucor’s Bylaws. With respect to the nominee, the notice must contain, among other things, (i) the nominee’s name, age and business and residential addresses; (ii) the nominee’s background and qualification, including, without limitation, the nominee’s principal occupation or employment; (iii) the class or series and number of shares or other securities of the Company directly or indirectly owned of record or beneficially by the nominee or any Stockholder Associated Person (as defined in Nucor’s Bylaws); (iv) any derivative positions held of record or beneficially by the nominee as well as any hedging transactions or similar agreements; (v) a written statement executed by the nominee (A) acknowledging that as a director of the Company, the nominee will owe a fiduciary duty under Delaware law with respect to the Company and our stockholders, (B) disclosing whether the nominee or any Stockholder Associated Person is a party to an agreement, arrangement or understanding with, or has given any commitment or assurance to, any person or entity as to how the nominee, if elected as a director of the Company, will act or vote on any issue or question, (C) disclosing whether the nominee or any Stockholder Associated Person is a party to an agreement, arrangement or understanding with any person or entity other than the Company with respect to any direct or indirect compensation, reimbursement or indemnification in connection with the nominee’s service or action as a director of the Company, (D) agreeing to update continually the accuracy of the information required by the immediately preceding clauses (B) and (C) for as long as the nominee is a nominee or a director of the Company

 2024 Proxy Statement 21

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

and (E) agreeing if elected as a director of the Company to comply with all corporate governance codes, policies and guidelines applicable to directors; and (vi) any other information regarding the nominee that would be required to be disclosed in a proxy statement or other filings required to be made in connection with a contested solicitation of proxies for the election of directors. With respect to the stockholder submitting the nomination, the notice must contain: (1) the name and address, as they appear on the Company’s books, of the stockholder and any Stockholder Associated Person; (2) the class or series and number of shares or other securities of the Company directly or indirectly owned of record or beneficially by the stockholder or any Stockholder Associated Person; (3) any derivative positions held of record or beneficially by the stockholder or any Stockholder Associated Person as well as any hedging transactions or similar agreements; (4) any other information regarding the stockholder or any Stockholder Associated Person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with a contested solicitation of proxies for the election of directors; and (5) a written statement whether either the stockholder or any Stockholder Associated Person will deliver a proxy statement and form of proxy to holders of the Company’s voting shares. A stockholder who is interested in recommending a director nominee should request a copy of Nucor’s Bylaws by writing to the Company’s Corporate Secretary at Nucor Corporation, 1915 Rexford Road, Charlotte, North Carolina 28211. In addition to satisfying the foregoing requirements under our Bylaws, to comply with the “universal proxy rules,” stockholders who intend to solicit proxies in support of director nominees at the 2025 annual meeting and who are not nominating directors through proxy access as described below must include the additional information required by Rule 14a-19(b) under the 1934 Act.

Nominating Directors through Proxy Access. A stockholder, or a group of up to 20 stockholders, that has owned continuously for at least three years shares of Nucor common stock representing an aggregate of at least 3% of the voting power of our issued and outstanding shares, may nominate and include in Nucor’s proxy materials for an annual meeting of stockholders a number of director nominees equal to the greater of (i) two nominees or (ii) 20% of the Board, provided that the stockholder(s) and the director nominee(s) satisfy the requirements specified in our Bylaws. A stockholder, or a group of stockholders, who is interested in submitting a proxy access director nomination should request a copy of Nucor’s Bylaws by writing to the Company’s Corporate Secretary at Nucor Corporation, 1915 Rexford Road, Charlotte, North Carolina 28211.

For the 2025 annual meeting of stockholders, notice of proxy access director nominees must be delivered to, or mailed and received at, the Company’s principal executive offices not later than the close of business on the 120^th day nor earlier than the close of business on the 150^th day before the first anniversary of the date the definitive proxy statement was first released to stockholders in connection with the Annual Meeting. As a result, notice of proxy access director nominees must be delivered, or mailed and received, not earlier than the close of business on October 23, 2024 and not later than the close of business on November 22, 2024. However, in the event that the date of the 2025 annual meeting of stockholders is more than 30 days before or more than 60 days after May 9, 2025, notice by the stockholder, or the group of stockholders, to be timely must be so delivered, or mailed and received, not earlier than the close of business on the 150^th day prior to the date of the 2025 annual meeting of stockholders and not later than the close of business on the later of the 120^th day prior to the date of such annual meeting or the 10^th day following the day on which public announcement of the date of such meeting is first made by the Company.

How to Communicate with the Board of Directors and Non-Management Directors. Stockholders and other interested parties can communicate directly with any of the Company’s directors by sending a written communication addressed to the individual director c/o Corporate Secretary at Nucor Corporation, 1915 Rexford Road, Charlotte, North Carolina 28211. Stockholders and other interested parties wishing to communicate with Mr. Kearney, as Lead Director, or with the non-management directors as a group may do so by sending a written communication addressed to Mr. Kearney c/o Corporate Secretary at the above address. All such communications are promptly reviewed before being forwarded to the addressee. Nucor generally will not forward to directors a communication that the Company determines to be primarily commercial in nature, relates to an improper or irrelevant topic or requests general information about the Company.

22   2024 Proxy Statement

DIRECTOR COMPENSATION

The Compensation and Executive Development Committee established the following director compensation amounts in 2022, and the amounts have not been changed since that time:

In addition to the cash fees described above, non-employee directors are granted each June 1 shares of Company common stock under the Nucor Corporation 2014 Omnibus Incentive Compensation Plan (the “Omnibus Plan”). Directors may elect to receive their shares in the form of deferred stock units. The number of shares of Company common stock awarded was equal to the quotient of $165,000 divided by the closing price of a share of Nucor common stock on the grant date (rounded down to the next whole share). All directors, other than Ms. Clayton, elected to receive their grant in the form of deferred stock units in 2023. The deferred stock units are fully vested on the grant date but are payable in the form of shares of Nucor common stock only after the termination of the director’s service on the Board.

The table below summarizes the compensation of each non-employee director who served on the Board for his or her Board and committee services during 2023. Directors who are also employees of Nucor (for 2023, Mr. Topalian) do not receive compensation (other than their compensation as employees of Nucor) for their service on the Board.

The table below summarizes the total number of vested deferred stock units granted to the non-employee directors under the Omnibus Plan, the Nucor Corporation 2010 Stock Option and Award Plan (the “2010 Plan”) and the Nucor Corporation 2005 Stock Option and Award Plan (the “2005 Plan”) that were outstanding as of December 31, 2023.

Outstanding Equity Awards at Fiscal Year-End

Director Stock Ownership Guidelines. To ensure that non-employee directors become and remain meaningfully invested in Nucor common stock, each non-employee director is required to own 7,000 shares of Nucor common stock (including deferred stock units). A non-employee director must meet the stock ownership requirement within five years of becoming a member of the Board. As of December 31, 2023, all of the non-employee directors were in compliance with the ownership requirement or in the first five years after becoming a director.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services to be performed by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. All such services provided for 2023 were pre-approved by the Audit Committee. The Audit Committee concluded that the provision of such services by PwC was compatible with the maintenance of that firm’s independence. The Audit Committee has delegated its authority to approve in advance all permissible non-audit services to be provided by PwC to the Chair of the Audit Committee; provided, however, any such services approved by its Chair shall be presented to the full Audit Committee at its next regularly scheduled meeting.

PROPOSAL 2:

RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has appointed the firm of PricewaterhouseCoopers LLP to serve as the independent registered public accounting firm of Nucor for 2024. PricewaterhouseCoopers LLP has acted in such capacity for Nucor since 1989. The Audit Committee reviewed and discussed the performance of PricewaterhouseCoopers LLP for 2023 prior to its appointment of PricewaterhouseCoopers LLP to serve as the Company’s independent registered public accounting firm for 2024.

The Company expects that representatives of PricewaterhouseCoopers LLP will participate in the Annual Meeting, and the representatives will have an opportunity to make a statement if they desire to do so. The Company also expects that the representatives will be available to respond to appropriate questions from stockholders.

Stockholder ratification of the Audit Committee’s appointment of PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm for 2024 is not required by our Bylaws or otherwise. Nevertheless, the Board is submitting the appointment of PricewaterhouseCoopers LLP to the Company’s stockholders for ratification as a matter of good corporate governance. If the Company’s stockholders fail to ratify the appointment, the Audit Committee will reconsider its appointment of PricewaterhouseCoopers LLP. Even if the Company’s stockholders ratify the appointment of PricewaterhouseCoopers LLP, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of Nucor and its stockholders.

Vote Recommendation

The Board of Directors recommends a vote “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP to serve as the Company’s independent registered public accounting firm for 2024.

COMPENSATION DISCUSSION AND ANALYSIS

Highlights of an Outstanding Year

Introduction

Our executive compensation program has consistently aligned with our performance as an industry leader that strives to generate profitable growth, maximize total stockholder return and promote a strong financial condition, while maintaining our commitment to safe and environmentally responsible operations.

Our stockholders are highly supportive of our program’s heavily leveraged, pay-for-performance compensation structure. Approximately 92% of stockholders present in person or represented by proxy and entitled to vote on the matter at our 2023 annual meeting of stockholders approved the advisory vote on our 2022 named executive officer compensation.

Based on our outreach efforts, we believe our stockholders appreciate the features of our executive compensation program that are designed to promote stability and facilitate smooth succession planning throughout the organization, and that they understand the long-term nature of our projects and the critical need for a workforce that can weather business cycles and continue to deliver industry-leading returns over the long term. Many Nucor teammates develop and progress through the Company, which allows us to execute on our multi-year, large-scale initiatives without disruption. Growing and developing our team from within is fundamental to who we are, with our executive team having an average of over 20 years of service.

This year’s Compensation Discussion and Analysis (referred to in this section and the “Executive Compensation Tables” section as “CD&A”) reviews the objectives and elements of Nucor’s executive compensation program and discusses the 2023 compensation earned by our named executive officers (“NEOs” or “Executive Officers”) listed in the table below. It also explains actions the Compensation and Executive Development Committee of the Board of Directors (referred to in this section and the “Executive Compensation Tables” section as the “Committee”) took to keep the executive compensation program aligned with stockholder interests and expectations, positioning Nucor to continue to attract, retain and develop the best leadership talent in our industry.

Stockholder Outreach and Board Responsiveness

Over the course of 2023, members of our senior management team held approximately 200 separate meetings with investors to share the details of our business strategy and explain the drivers of our performance. These were largely in-person meetings at Nucor facilities and investor conferences, but also included video conferences and telephone calls.

 2024 Proxy Statement 27

EXECUTIVE OFFICER COMPENSATION

In November 2023, Leon J. Topalian, our Chair, President and CEO, and Gregory J. Murphy, our Executive Vice President of Business Services and General Counsel, hosted an investor webcast during which they discussed our plans for reducing our GHG emissions intensity over time and accomplishing net-zero by 2050, consistent with the International Energy Agency’s glidepath for the steel sector. More than 50 institutional investors and financial analysts participated in the live webcast and the recorded version available on our website has been viewed more than 100 times.

We continue to engage in follow-up communications with the stewardship teams representing several of our larger stockholders on this important topic and others, including executive compensation, other nature-related risks and opportunities, safety, and diversity and inclusion at Nucor.

During the course of these interactions, we have heard an appreciation for our culture and values, and continued endorsement for the principles at the core of our executive compensation program — maintaining a heavy emphasis on variable pay/total compensation and retaining key talent and team-based incentives that align with the long-term investment philosophies of our stockholders. Stockholders have also acknowledged our leadership on GHG emissions and environmental stewardship broadly, as well as our consistent focus on the health and safety of our team.

As a result of this outreach, we have gained a better understanding of investor expectations surrounding both the evolution of our business strategy and our disclosures with respect to environmental and human capital management, and we have shared these learnings with our Board of Directors. Management also presented summaries of the stockholder outreach activity and the feedback from stockholders to the Committee at its meetings throughout the year. The Committee regularly considers stockholder feedback as it makes compensation decisions.

EXECUTIVE SUMMARY

2023 Business Overview

Over the course of 2023, our team delivered outstanding financial and operating results while working safely and responsibly. With consolidated net earnings of $4.52 billion and diluted earnings per share of $18.00, 2023 was the third most profitable year in Company history. Our strong financial performance is the result of years of work investing to strategically position and grow our portfolio of capabilities across the steel value chain.

Our number one cultural value is the safety and well-being of our Nucor team. For the fifth consecutive year, our team achieved improved safety performance with an injury and illness rate that was 17% lower than in 2022 and much lower than the steel industry average. Our team achieved this performance during a period of considerable expansion, with multiple sites under construction or in a start-up phase, which is a testament to our continued focus on our goal of becoming the world’s safest steel company and on our mission to grow the core, expand beyond and live our culture.

By executing operationally across our business lines and, in parallel, investing in Nucor’s future, we are generating attractive returns for our stockholders and positively impacting our local communities. In December 2023, we announced an increase in our regular quarterly cash dividend by 6% to $0.54 per share. Nucor has increased its base dividend for 51 consecutive years – every year since it first began paying dividends in 1973.

With our pay-for-performance compensation structure, Nucor’s strong financial performance rewards teammates across all levels of the Company. Nucor teammates participate in bonus plans and profit sharing that align their pay with the Company’s overall financial results. Our profit-sharing plan (in which our officers do not participate) provided our teammates with current income and retirement plan contributions of more than half a billion dollars for 2023.

Our leadership team is proud of where the Company stands today and is optimistic about where we are headed. Since the beginning of 2020, we have generated net earnings of nearly $20 billion and we have returned $9.7 billion to stockholders, representing approximately 50% of our earnings. During the same four-year period, our annual ROE has averaged 30%.

28   2024 Proxy Statement

EXECUTIVE OFFICER COMPENSATION

We plan to continue to broaden our capabilities so Nucor remains well positioned to serve our customers. This long-term focus has enabled us to deliver industry leading performance in safety, profitability and sustainability, keeping pace with other leading industrial companies. We pioneered the use of recycling to make new steel, which has positioned Nucor as one of the cleanest steelmakers in the world, and we are capitalizing on the opportunity to supply the sustainable steel that is building our 21^st century economy.

How Corporate Social Responsibility Impacts Compensation Decisions

Share the Pain, Share the Gain: Nucor’s Approach to Executive Compensation

Nucor designed and built its executive compensation program with pay-for-performance at its core. The result is a program that is highly leveraged – the majority of our executive compensation is variable and directly linked to Nucor’s relative performance and the value created for its stockholders. Below is an overview of the key features of our program:

 2024 Proxy Statement 29

EXECUTIVE OFFICER COMPENSATION

The bottom line is that for any given year, if Nucor performs poorly, Executive Officers will be paid below the market median. On the other hand, if performance is outstanding, Executive Officers will be paid above the market median. By providing this balanced compensation approach, Nucor provides Executive Officers with a reasonable measure of security regarding the minimum level of compensation they are eligible to receive, while motivating them to focus on the business measures that will produce a consistently high level of performance for Nucor and return for its stockholders. Decisions about the actual amount or value of compensation granted to each Executive Officer are based on actual Nucor performance. Individual performance does not influence incentive plan payouts.

2023 Compensation Overview

Below is an overview of how our executive compensation plans functioned in 2023:

The Committee has the right to exercise discretion to reduce an incentive plan payout to ensure that payouts from any incentive plan produce their desired result. However, the Committee may not exercise discretion to increase a payout. For 2023, the Committee reviewed the payouts and determined that the incentive plan payouts were appropriate and, therefore, did not reduce the incentive plan payouts.

Best Practice Compensation Governance Features

Our executive compensation program is grounded in the following policies and practices, which promote sound compensation governance, reflect our executive compensation philosophy and further align our Executive Officers’ interests with those of our stockholders.

WHAT GUIDES OUR PROGRAM

Program Aligned with Strategy

Nucor’s executive compensation program continues to support our strategy. We expect to achieve the sustained creation of incremental stockholder value by growing our core steelmaking businesses through disciplined execution, selectively expanding beyond our traditional product offerings into adjacent areas where we believe we can create and build on a sustainable competitive advantage and living our Nucor culture each day.

Our culture values safety above all else, relies on trust and open communication to facilitate the teamwork that is essential to driving results and remains committed to the community stewardship that is critical to building trust among all our stakeholders, helping to ensure that we can all succeed together.

Our Executive Compensation Philosophy

Nucor believes that executive compensation should be commensurate and aligned with the performance of Nucor and the creation of long-term stockholder value. To this end, our executive compensation program is designed to pay above the market median when Nucor’s performance is outstanding and provide compensation below the market median when performance is below Nucor’s peers. The following key principles form the core of our executive compensation philosophy:

 2024 Proxy Statement 31

EXECUTIVE OFFICER COMPENSATION

Our executive compensation philosophy is supported by the following elements of our executive compensation program:

These compensation elements provide a balanced mix of guaranteed compensation and variable, at-risk compensation with an emphasis on performance-based annual and long-term incentives. The Committee annually considers adjustments to base salaries (which impact incentive plan opportunities) and periodically reviews the level of annual and long-term incentives to ensure that the mix of base salary and annual and long-term incentives, and the target incentive opportunities, are appropriate to accomplish the goal of paying near the market median total compensation for industrial and materials companies of similar size over a multi-year business cycle.

Pay Mix

As illustrated below, the majority of total direct compensation opportunity of our CEO and other Executive Officers is performance-based at-risk (76% and 75%, respectively). In addition, the majority of target compensation of the CEO and other Executive Officers is long-term (74% and 60%, respectively). The graphs depict the mix of total target direct compensation set for our CEO and other Executive Officers for the 2023 plan year.

EXECUTIVE OFFICER COMPENSATION

The Role of Compensation Peer Companies and Performance Comparator Groups

Compensation Peer Companies. Nucor periodically benchmarks Executive Officer compensation to ensure that the compensation opportunities are reasonable. Nucor does not set compensation according to benchmark data. The Committee’s only formal relationship with benchmark data is generally to set base salaries near or below the market median.

In December 2021, Pearl Meyer provided the Committee with the results of its benchmarking of Nucor’s compensation against the 21 Compensation Peer Companies listed in the table below. In addition to benchmarking Executive Officer compensation at target and actual levels of pay, the Committee completed an exercise to understand how the compensation of Executive Officers compared to compensation of the peer group at various levels of performance (below threshold, threshold, target and maximum). Nucor’s compensation philosophy is to pay below market when performance is below peers and to pay above market when performance is outstanding. The intent is to provide market levels of compensation over the business cycle.

Some of the above companies are included in the Steel Comparator Group or the General Industry Comparator Group used in the incentive plans as described below. However, these companies were chosen based on size and industry, while the companies used in the incentive plans are all steel companies in the case of the Steel Comparator Group or met the criteria discussed below in the case of the General Industry Comparator Group. The Committee does not benchmark compensation levels and practices against the companies in the Steel Comparator Group because some of them are substantially smaller than Nucor. The Committee does not benchmark compensation to the General Industry Comparator Group because compensation data from these companies may result in above median benchmark data due to their higher than median performance.

Performance Comparator Groups. The Committee believes that performance should be measured both in absolute terms (meaning based on achieving or exceeding performance measures established by the Committee) and relative to other companies. Two performance comparator groups are used to measure relative performance: the Steel Comparator Group and the General Industry Comparator Group. These comparator groups are used in the AIP and the LTIP – they are not used for purposes of benchmarking compensation.

The Committee reviews the performance comparator groups annually. Companies may be added to or dropped from the performance comparator groups based on product mix (in the case of the Steel Comparator Group) or business changes, performance or product mix (in the case of the General Industry Comparator Group). The Committee designates the members of each performance comparator group at the beginning of each performance period. Since some of the performance periods are as long as three years, it is possible that the performance comparator group used for one performance period may differ from the group used in a different performance period.

2023 EXECUTIVE COMPENSATION IN DETAIL

Determination of 2023 Compensation

In making its determinations with respect to executive compensation for 2023, the Committee was supported by Nucor’s Vice President and Corporate Secretary, and Nucor’s Vice President of Human Resources and Safety. In addition, the Committee engaged the services of Pearl Meyer to serve as its independent compensation consultant and, in such capacity, to assist the Committee’s review and determination of the compensation of the Executive Officers. Pearl Meyer also was retained to assist the Committee with additional projects, including benchmarking Executive Officer compensation, reviewing and developing alternatives for the performance comparator groups, reviewing the incentive plans, monitoring trends in executive and non-employee director compensation, preparing tally sheets and assisting in the preparation of this CD&A.

The Committee retained Pearl Meyer directly although, in carrying out its assignments, Pearl Meyer also interacted with Nucor management when necessary and appropriate. Specifically, the Vice President and Corporate Secretary and the Vice President of Human Resources and Safety interacted with Pearl Meyer to provide compensation and performance data for Executive Officers and Nucor. In addition, Pearl Meyer may, in its discretion, seek input and feedback from the CEO and the Chief Financial Officer regarding its work product prior to presenting such work product to the Committee to confirm the work product’s alignment with Nucor’s business strategy, determine what additional data needs to be gathered or identify other issues, if any.

The Committee frequently requested Mr. Topalian, as CEO, to be present at Committee meetings where executive compensation and Company performance were discussed and evaluated. Mr. Topalian was free to provide insight, suggestions or recommendations regarding executive compensation during these meetings or at other times; however, only independent Committee members were allowed to vote on decisions made regarding executive compensation.

The Committee met separately with the CEO to discuss his compensation, but the Committee made decisions regarding Mr. Topalian’s compensation in executive session, based solely upon the Committee’s deliberations. The Committee’s decisions regarding the compensation of Executive Officers (other than the CEO) were made after considering recommendations from the CEO.

Base Salary

The Committee’s goal is to set Executive Officers’ base salaries near or below the market median base salary level for comparable positions at similar size industrial and materials companies, because of the Committee’s desire to orient Executive Officers’ total pay significantly toward variable, at-risk incentive compensation. When promoted, Executive Officer salaries are set below the market median. As Executive Officers gain experience and perform, they may receive larger increases to move them closer to the median of the benchmark data. No salary increases were made in 2021, except for those Executive Officers receiving a promotion. In 2022 and again in 2023, salaries were increased at rates above market in order to bring salaries closer to the median. Base salaries for 2023 were as follows:

Annual Incentives

The AIP provides Executive Officers an opportunity to receive annual cash incentive awards based on Nucor’s annual performance. The incentive opportunity is expressed as a percentage of base salary.

Seventy-five percent of the maximum award available under the AIP is earned based on Nucor’s ROE and 25% of the maximum award available under the AIP is earned based on Nucor’s annual ROAIC compared to the annual ROAIC of members of the Steel Comparator Group (identified on page 34). The allocation of the AIP award between the two performance measures is as follows:

For 2023, the Committee set the threshold, target and maximum ROE levels as follows:

A prorated incentive award is earned for ROE between 4% at threshold, 8.5% at target and 17% at maximum.

The Committee also set the ROAIC portion of the AIP award for 2023 that could be earned based on Nucor’s annual ROAIC compared to the annual ROAIC of members of the Steel Comparator Group as follows:

Executive Officers may elect to defer up to one-half of their AIP award into Nucor common stock units. The AIP provides an incentive for Executive Officers to defer their AIP awards by providing a grant of additional Nucor common stock units equal to 25% of the number of common stock units deferred. An Executive Officer is always vested in the common stock units attributable to the deferred award. The deferral incentive units become vested upon the Executive Officer’s attainment of age 55, death or disability while employed by Nucor. The vested common stock units are distributed to the Executive Officer in the form of Nucor common stock following the Executive Officer’s retirement or other termination of employment. Dividend equivalents are paid on deferred common stock units (including the deferral incentive units) in cash within 30 days of when stockholder dividends are paid.

Four Executive Officers – Messrs. Topalian, Laxton, Sumoski and Needham – elected to defer a portion of their AIP award payout in 2023.

2023 Performance Results and AIP Payout

Based on Nucor’s ROE of 22.87% and being ranked third within the Steel Comparator Group for ROAIC for 2023, the CEO and the other Executive Officers earned total AIP awards of 375% and 281.25% of base salary, respectively, as follows:
