2         2018 Proxy Statement

GENERAL INFORMATION

The enclosed proxy is being solicited by the Board of Directors (the “Board of Directors” or the “Board”) of Nucor Corporation (“Nucor,” the “Company,” “we,” “us” or “our”) for use at the 2018 annual meeting of stockholders (the “Annual Meeting”) to be held at 10:00 a.m., Eastern Time, on Thursday, May 10, 2018 at the Charlotte Marriott SouthPark (Morrison Ballroom) located at 2200 Rexford Road, Charlotte, North Carolina 28211. Directions to the location of the Annual Meeting may be obtained by calling (704) 366-7000.

Delivery of Proxy Materials

We have elected to distribute a notice regarding the availability of proxy materials on the Internet, rather than sending a full set of these materials in the mail, to most of our stockholders. The notice, or a full set of the proxy materials (including this Proxy Statement and form of proxy), as applicable, was sent to stockholders beginning March 23, 2018, and the proxy materials were posted on the investor relations portion of the Company’s website, www.nucor.com/investor, and on the website referenced in the notice on the same day. Utilizing this method of proxy delivery expedites receipt of proxy materials by 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 is not a part of this Proxy Statement.

Shares Entitled to Vote; Quorum

The record date for the Annual Meeting is March 12, 2018. Only holders of record of Nucor’s common stock as of the close of business on that date will be entitled to vote at the Annual Meeting. As of the record date, 318,091,361 shares of Nucor common stock were outstanding. The presence, in person or by proxy, of the holders of a majority of the shares of Nucor common stock issued, outstanding and entitled to vote at the Annual Meeting is necessary to constitute a quorum for the transaction of business at the Annual Meeting.

Voting Rights and Procedures

Each share of Nucor common stock outstanding 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 holders of the enclosed proxy will have the discretionary authority to cumulate votes in the election of directors.

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

Votes Required to Approve Each Proposal

The following are the voting requirements for each proposal:

Proposal 1, Election of Directors.    Directors shall be elected by a plurality of the votes cast (meaning that the seven 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 as described below.

Proposal 2, Ratification of the Appointment of Independent Registered Public Accounting Firm.    Ratification of the appointment of PricewaterhouseCoopers LLP as Nucor’s independent registered public accounting firm for 2018 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 Named Executive Officer Compensation.    Approval, on an advisory basis, of the proposal requires the affirmative vote of the holders of a majority of shares present in person or

    2018 Proxy Statement    3

GENERAL INFORMATION

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 4, Stockholder Proposal.    Approval of the stockholder proposal 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).

Other Items.    For any other matters, 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 will be required for approval (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).

“Withhold” Votes, Abstentions and Broker “Non-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.

Under the New York Stock Exchange rules and regulations (the “NYSE rules”), proposal 2, the ratification of the appointment of PricewaterhouseCoopers LLP as Nucor’s independent registered public accounting firm for 2018, 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, proposals 1, 3 and 4, the election of directors, the advisory vote to approve Nucor’s named executive officer compensation in 2017 and the stockholder proposal, respectively, are “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 have no effect on the outcome of the proposal. “Withhold” votes will also generally have no effect on the outcome of the proposal. However, the Board of Directors has adopted a Corporate Governance Principle intended to give effect to “withheld” 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 votes “withheld” from his or her election than votes “for” his or her election to promptly tender his or her resignation to the Secretary of the Company following certification of the stockholder vote for consideration by the Board.

With respect to proposals 2, 3 and 4, the ratification of the appointment of PricewaterhouseCoopers LLP as Nucor’s independent registered public accounting firm for 2018, the advisory vote to approve Nucor’s named executive officer compensation in 2017 and the stockholder proposal, respectively, you may vote “for” or “against” the proposals, or you may “abstain” from voting on the proposals. An abstention will be counted as a vote present or represented and entitled to vote on the proposals and will have the same effect as a vote “against” the proposals, and a broker “non-vote” will not be considered entitled to vote on these proposals and will therefore have no effect on their outcome. As discussed above, because proposal 2, the ratification of the appointment of PricewaterhouseCoopers LLP as Nucor’s independent registered public accounting firm for 2018, 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. Proxies voted by telephone or via the Internet must be properly completed pursuant to this solicitation. If you specify your vote regarding any matter presented at the

4         2018 Proxy Statement

GENERAL INFORMATION

Annual Meeting, your shares will be voted by one of the individuals indicated on the proxy in accordance with your specification. If you do not specify your vote, your shares will be voted:

• FOR the election of the seven director nominees;

• FOR the ratification of the appointment of PricewaterhouseCoopers LLP as Nucor’s independent registered public accounting firm for 2018;

• FOR the approval, on an advisory basis, of Nucor’s named executive officer compensation in 2017; and

• AGAINST the approval of the stockholder proposal.

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 by telephone, the Internet or mail until the applicable deadline for each method; or (iii) attending the Annual Meeting and voting in person. Attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically make that request or vote in person at the Annual Meeting. 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 change or revoke your voting instructions by following the specific instructions provided to you by your broker, bank, trustee or other nominee, or, if you have obtained a legal proxy from your broker, bank, trustee or other nominee, by attending the Annual Meeting and voting in person.

    2018 Proxy Statement    5

PROPOSAL 1

ELECTION OF DIRECTORS

The number of directors is currently fixed at eight. Gregory J. Hayes is not standing for reelection at the Annual Meeting. Mr. Hayes has been a director since 2014, serving as a member of the Audit, Compensation and Executive Development, and Governance and Nominating Committees during such time, and as Chairman of the Audit Committee since 2014. Mr. Hayes 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 seven members.

On the recommendation of the Governance and Nominating Committee, the Board of Directors has nominated the seven persons named below for election as directors at the Annual Meeting. If elected, each nominee will serve until his or her term expires at the 2019 annual meeting of stockholders or until his or her successor is duly elected and qualified. All of the nominees are currently serving as directors and were elected to the Board at the 2017 annual meeting of stockholders except for U.S. Army General (retired) Lloyd J. Austin III, who was elected to the Board in September 2017. General Austin was initially identified to the Board as a potential director by a non-management director. Each 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 of Directors knows of no reason why any of these 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 of Directors 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 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 Secretary of the Company following certification of the stockholder vote for consideration by the Board. 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 seven nominees listed below. Unless otherwise specified, proxies will be voted FOR each nominee.

Based solely on a review of such reports and written representations made by Nucor’s directors and executive officers with respect to the completeness and timeliness of their filings, Nucor believes that the reporting persons complied with all applicable Section 16(a) filing requirements on a timely basis during 2017.

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 of Directors 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 eight members, seven of whom are independent. If the director nominees are elected at the Annual Meeting, the Board of Directors will have seven members, six 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, functioning of the Board and its committees, compensation of directors, and annual performance evaluations of the Board, its committees, individual directors and our Chief Executive Officer.

Codes of Ethics.    The Board has adopted a Code of Ethics for Senior Financial Professionals that applies to the Company’s Chief Executive Officer, 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 employees, officers and directors of the Company. The Company intends to post any amendments or waivers to 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/governance.

Documents Available.    All 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 and the Standards of Business Conduct and Ethics, are available on the Company’s website at www.nucor.com/governance. Any modifications to these corporate governance materials will be reflected on the Company’s website.

Director Independence.    The Board believes that a majority of its members are independent under both the applicable NYSE rules and the applicable SEC rules and regulations (the “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 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/governance.

In February 2018, the Board of Directors, 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 and affiliates) and each of Nucor, its management and its independent registered public accounting firm, including (i) with respect to Mr. Hayes, who serves as Chairman, President, Chief Executive Officer and a director of United Technologies Corporation, that Nucor in the ordinary course of business purchased from and sold to United Technologies goods in 2017 in an amount less than 0.75% of the consolidated gross revenues of United Technologies; and (ii) with respect to Mr. Dempsey, who serves as President, Chief Executive Officer and a director of Barnes Group Inc., that Nucor in the ordinary course of business purchased from and sold to Barnes Group goods in 2017 in an amount less than 0.75% of the consolidated gross revenues of Barnes Group. 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. Ferriola’s in his capacity as Nucor’s Chairman, Chief Executive Officer and President) all fall well below the thresholds in the Categorical Standards. Consequently, the Board of Directors determined that General Austin and each of Messrs. Dempsey, Hayes, Kearney and Walker and Dr. Haynes and Ms. Koellner is an independent 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

12         2018 Proxy Statement

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

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) of the 1934 Act, and that each member of the Compensation and Executive Development Committee is an “outside director” as defined under Section 162(m) of the Internal Revenue Code.

Board Leadership Structure.    John J. Ferriola currently holds the positions of Chairman of the Board, Chief Executive Officer and President of the Company. The Corporate Governance Principles of the Company provide that whenever the Chairman of the Board is a member of management, there shall be a Lead Director. The Lead Director is an independent director appointed annually by the independent members of the Board, and he or she serves at the pleasure of the Board. In February 2017, the Board appointed John H. Walker to serve as Lead Director. The Board’s leadership structure is outlined in the Company’s Bylaws and Corporate Governance Principles, as described below:

Chairman of the Board	The Board has appointed the Company’s Chief Executive Officer and President as its Chairman. Appointing Mr. Ferriola as Chairman (i) enhances alignment between the Board and management in strategic planning and execution as well as operational matters, and (ii) streamlines Board process in order to conserve time for the consideration of the important matters the Board needs to address.
Lead Director	The Lead Director (i) provides leadership to the Board of Directors; (ii) chairs Board meetings in the absence of the Chairman; (iii) organizes, sets the agenda for and leads executive sessions of the non-employee directors and/or independent directors without the attendance of management; (iv) serves as a liaison between the Chairman, the non-employee directors and the independent directors; (v) consults with the Chairman and the Secretary of the Company to approve the agenda for each Board meeting and the information that shall be provided to the directors for each scheduled meeting; (vi) approves meeting schedules to assure that there is sufficient time for discussion of all agenda items; (vii) meets with the Chairman between Board meetings as appropriate in order to facilitate Board meetings and discussions; (viii) has the authority to call meetings of the non-employee directors and the independent directors; and (ix) is available for consultation and direct communication with major stockholders.
Independent Directors	Independent directors comprise more than 85% of the Board and 100% of the Audit Committee, the Compensation and Executive Development Committee and the Governance and Nominating Committee.
Committee Chairs	All chairs of the Board’s committees are independent and are annually appointed by the Board, approve agendas and material for respective committee meetings and act as a liaison between committee members and the Board and senior management.

    2018 Proxy Statement    13

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

Board Committees.    The Board of Directors 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 of Directors. Committee members and committee chairs are appointed by the Board. The members of these committees are identified in the table below:

The Board has determined that Mr. Hayes is an “audit committee financial expert” within the meaning of the SEC rules and that he has accounting and related financial management expertise within the meaning of the NYSE rules. All members of the Audit Committee are 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 of Directors held four meetings during 2017. Each incumbent director attended 75% or more of the aggregate number of meetings of the Board and committees of the Board on which such director served during 2017. Pursuant to the Corporate Governance Principles, the non-employee directors meet in executive session prior to or after each quarterly Board meeting and as necessary prior to or after other Board meetings. Mr. Walker, as Lead Director, presides over these executive sessions.

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 attended last year’s annual meeting.

Annual Evaluation of Directors and Committee Members.    The Board of Directors evaluates the performance of each director, each committee of the Board, the Chairman, the Lead Director and the Board of Directors 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 Chairman, the Lead Director and the Board of Directors as a whole. The entire Board of Directors reviews 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, the Chairman and the Lead Director.

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. Certain other important categories of risk are assigned to designated Board committees (which are comprised 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 risk exposures, including, but not limited to, legal and environmental claims and liabilities, risk management and other financial exposures, and the steps management has taken to monitor and control such exposures, including the Company’s risk

    2018 Proxy Statement    15

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

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 presentation, the Audit Committee meets with management to provide its comments on the report and 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 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 Board believes that its ability to oversee risk is enhanced by having one person serve as the Chairman of the Board and the Chief Executive Officer. With his in-depth knowledge and understanding of the Company’s operations, the Board believes Mr. Ferriola, as Chairman, Chief Executive Officer and President, is better able to bring key strategic and business issues and risks to the Board’s attention than would a Non-Executive Chairman of the Board or a non-director Chief Executive Officer.

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 provide any services to Nucor except for services related solely to executive officer and director compensation. Please see “Executive Officer Compensation – Compensation Discussion and Analysis – 2017 Executive Compensation in Detail – Determination of 2017 Compensation” on page 28 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 or Short Selling.    Nucor maintains policies that apply to all officers, certain designated employees and the members of the Board that prohibit hedging or short selling (profiting if the market price of the securities decreases) of Nucor securities.

Policy on Executive Officer Incentive Compensation Recoupment.    The Company has a written policy to address the recoupment of performance-based compensation awarded to or earned by an executive officer if there is a restatement of the Company’s financial results due to material noncompliance of the Company with any financial reporting requirement under the federal securities laws. In the event of such a restatement, the Compensation and Executive Development Committee shall review the performance-based compensation awarded to or earned by the executive officers for the three-year period prior to the restatement event and, if the Committee determines in its reasonable discretion that any such performance-based compensation would not have been awarded to or earned by an executive officer based on the restated financial results, the Committee shall within 12 months of the restatement event, to the extent practicable, seek to recover from such executive officer any portion of the performance-based compensation that is greater than that which would have been awarded or earned had it been calculated on the basis of the restated financial results. A copy of the policy is available on our website at www.nucor.com/governance.

Policy on Transactions with Related Persons.    The Company has a written policy and procedures for the review, approval or ratification of any transactions that could potentially be required to be reported under the SEC rules for disclosure of transactions with the Company’s directors, 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 several 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

16         2018 Proxy Statement

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

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.

In 2017, Smoot Enterprises, Inc. was paid approximately $4.14 million by Nucor to transport products and materials for Nucor. Michael Smoot, who is the brother-in-law of Ladd R. Hall, an executive officer of Nucor, is an officer and greater than 10% owner of Smoot Enterprises, Inc. The foregoing was approved under Nucor’s policy on transactions with related persons.

In 2017, Danny Pantello, a melt shop supervisor at Nucor, was paid compensation of approximately $148,600. Mr. Pantello is a stepson of R. Joseph Stratman, an executive officer of Nucor. The foregoing was approved under Nucor’s policy on transactions with related persons.

Nominating Directors.    Stockholders may recommend a director candidate for consideration by the Governance and Nominating Committee by submitting the candidate’s name in accordance with provisions of Nucor’s Bylaws that require advance notice to Nucor 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 preceding year’s annual meeting of stockholders nor earlier than the close of business on the 150^th day before the first anniversary of the preceding year’s annual meeting of stockholders; provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, 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 such annual meeting 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, business and residential addresses, (ii) the nominee’s background and qualification, (iii) the 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 its 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, 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 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 our books, of that stockholder and any Stockholder Associated Person, (2) the number of shares or other securities of the Company directly or indirectly owned of record or beneficially by that 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 that 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 that 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 candidate should request a copy of Nucor’s Bylaw

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

provisions by writing to Nucor’s Corporate Secretary at Nucor Corporation, 1915 Rexford Road, Charlotte, North Carolina 28211.

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 shall 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 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 Board of Directors in identifying and evaluating potential director nominees, and Nucor may do so again in the future.

The Governance and Nominating Committee is committed to having diverse individuals from different backgrounds with varying perspectives, professional experience, education and skills serving as directors. In evaluating potential nominees for election and reelection as members of the Board, the Governance and Nominating Committee considers persons with a variety of perspectives, professional experience, education and skills that possess the below minimum qualifications. The potential nominee must:

• be a person of the highest integrity and must be committed to ethical standards of personal and corporate behavior;

• have significant business experience or other organizational leadership experience that will allow the nominee to contribute significantly to the Company as a member of the Board;

• if not a member of the Company’s management, not have any relationships, directly or through an immediate family member, with the Company that would make him or her not able to serve as an independent director within the meaning of any rules and laws applicable to the Company;

• have a willingness and an ability to make the necessary time commitment to actively participate as a member of the Board; and

• be able to represent the interests of all of Nucor’s stockholders and not merely those of one stockholder or a special interest group.

The Governance and Nominating Committee also believes there are certain specific qualities or skills that one or more members of the Board of Directors must possess. These include:

• the skills and experience necessary to serve as an audit committee financial expert;

• experience serving as the chief executive officer of, or in another senior management position with, a major manufacturing company;

• significant and successful merger and acquisition experience; and

• diversity in terms of race or gender.

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

DIRECTOR COMPENSATION

In 2017, the Compensation and Executive Development Committee engaged Pearl Meyer to evaluate Nucor’s director compensation against the industrial and materials companies listed in the table on page 26 used to benchmark executive compensation (except for Tyco International Ltd. which was acquired and removed from the peer group after the executive compensation benchmarking was completed). Director compensation survey data was also reviewed. Director pay was last changed in 2014. The benchmarking showed that the cash portion of director compensation had fallen below the market median. In order to bring the total director compensation near the market median, the following director compensation amounts became effective May 11, 2017.

Board/Committee Position	2017 Annual Cash Fees ($)		2016 Annual Cash Fees ($)
Lead Director		157,000		127,000
Board Member (non-employee directors)		125,000		95,000
Audit Committee Chairman		25,000		25,000
Compensation and Executive Development Committee Chairman		20,000		17,000
Governance and Nominating Committee Chairman		15,000		14,000

Directors who are not senior officers of Nucor are granted each June 1 shares of Company stock under the Company’s 2014 Omnibus Incentive Compensation Plan (the “2014 Plan”). Directors may elect to receive their shares in the form of deferred stock units. Effective June 1, 2017 and unchanged since 2014, the number of shares of Company stock awarded was equal to the quotient of $140,000 divided by the closing price of a share of Nucor common stock on the grant date (rounded down to the next whole share).

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 the year ending December 31, 2018. PricewaterhouseCoopers LLP has acted in such capacity for Nucor since 1989.

The Company expects that representatives of PricewaterhouseCoopers LLP will be present at 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 as our independent registered public accounting firm is not required by our Bylaws or otherwise. Nevertheless, the Board is submitting the appointment of PricewaterhouseCoopers LLP to the stockholders for ratification as a matter of good corporate governance. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider its appointment of PricewaterhouseCoopers LLP. Even if the 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 as the Company’s independent registered public accounting firm for the year ending December 31, 2018. Unless otherwise specified, proxies will be voted FOR the proposal.

EXECUTIVE OFFICER COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis (referred to in this section and the “Executive Compensation Tables” section as the “CD&A”) outlines Nucor’s executive compensation philosophy, objectives and processes. It also explains how the Compensation and Executive Development Committee of the Board (referred to in this section and the “Executive Compensation Tables” section as the “Committee”) made executive compensation decisions in 2017 for the named executive officers (the “Executive Officers”) listed below.

Executive Officer	Principal Positions
John J. Ferriola	Chairman, Chief Executive Officer and President
James D. Frias	Chief Financial Officer, Treasurer and Executive Vice President
James R. Darsey	Executive Vice President-Raw Materials
Ladd R. Hall	Executive Vice President-Flat-Rolled Products
R. Joseph Stratman	Chief Digital Officer and Executive Vice President

EXECUTIVE SUMMARY

2017 Business Overview

In 2017, Nucor delivered robust year-over-year profit growth and its highest earnings since the cyclical peak year of 2008. This performance shows that Nucor’s disciplined strategy for profitable growth continues to work. Our successful execution is evident in our strong cash flow generation and our industry-leading returns on capital through the challenging steel markets of recent years. Most importantly, we believe our strategic execution positions Nucor to deliver stronger profitability throughout the economic cycle.

Return on equity (“ROE”) and return on average invested capital (“ROAIC”) improved in 2017 both on an absolute basis and relative to our comparator groups. Our incentive compensation programs worked as intended as improved absolute and relative performance resulted in larger year-over-year incentive payouts.

Say-on-Pay Vote and Feedback from Stockholders

Beginning in 2018, Nucor will submit its compensation program for the Executive Officers to an annual advisory say-on-pay vote of its stockholders. In 2017, approximately 96% of the total votes cast at Nucor’s annual stockholders meeting supported the executive compensation program. The Committee pays careful attention to any feedback it receives from stockholders about the program, including the say-on-pay vote. The Committee considered the strong stockholder endorsement in 2017 of the Committee’s decisions and policies and Nucor’s overall executive compensation program in continuing the pay-for-performance program that is currently in place.

The Board of Directors recommends a vote for the annual advisory vote on Executive Officer compensation (Proposal 3).

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 – a significant portion of compensation is variable and directly linked to Nucor’s relative performance and the value delivered to its stockholders. Here is an overview of how it works:

› Base salaries are set below the median for similar size industrial and materials companies. Accordingly, the Committee recognizes that Executive Officers may earn below median levels of compensation when Nucor’s performance is below its peers, even if an Executive Officer’s individual performance may be superior. This practice has resulted, and may result in the future, in Executive Officers earning less than their peer company counterparts.

› The incentive plans measure performance relative to two performance comparator groups: the Steel Comparator Group and the General Industry Comparator Group. The companies included in these comparator groups are reviewed annually by the Committee. Please see “Performance Comparator Groups” on page 27 of this CD&A for more information. The incentive plans are designed to pay well when performance is high and potentially not pay any incentive if performance is poor.

    2018 Proxy Statement    23

COMPENSATION DISCUSSION AND ANALYSIS

› Through a multi-year business cycle, total compensation outcomes should be aligned with the median of Nucor’s steel company peers and other similar size industrial and materials companies. The incentive plans are based on analysis that assumes some years of lower performance where no payouts may be earned and some years where maximum payouts may be achieved – to reflect fluctuations in economic activity and performance relative to peers.

› A significant amount of equity must be held until retirement. Nucor maintains a higher than market level stock ownership requirement, which aligns the interests of our Executive Officers with those of our stockholders.

› Nucor takes an egalitarian approach to providing benefits to our employees. In fact, certain benefits, such as Nucor’s Profit Sharing, Scholarship Program, Employee Stock Purchase Plan, Extraordinary Bonus and Service Awards Program, are not available to Executive Officers, and Executive Officers do not receive supplemental executive perquisites, such as company cars, country club memberships or personal use of corporate aircraft.

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 the 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 with regard to the actual amount or value of compensation granted to each Executive Officer are based on actual Nucor performance. Individual performance is not taken into account.

2017 Compensation Overview

Nucor’s executive compensation plans worked as designed in 2017.

• Base salaries: Executive Officer salaries were modestly increased. The increases for the Chief Executive Officer and the Chief Financial Officer were modestly more than the increases for the other executives (5% and 6%, respectively, versus 2%) to move them closer to the market median. However, base salaries for all executives are still set below the market median, which is consistent with our compensation philosophy.

• Annual incentives: Our Executive Officers earned an annual incentive reflecting Nucor’s ROE and ROAIC performance as compared to the Steel Comparator Group. Performance in 2017 was materially better than 2016. The Committee changed one of the annual incentive performance measures from relative revenue performance to relative ROAIC. As Nucor continues to pursue a growth strategy that includes vertical integration, the Committee believes ROAIC is a more relevant measure of performance than revenue growth.

• Long-term incentives: The Senior Officers Long-Term Incentive Plan (the “LTIP”) rewarded Executive Officers for Nucor’s strong performance during the three-year performance period ended December 31, 2017 relative to the Steel Comparator Group (ranked second out of six), but resulted in a modest payout for the three-year performance period ended December 31, 2017 relative to the General Industry Comparator Group (ranked seventh out of 11). Please see “Performance Comparator Groups” on page 27 of this CD&A for descriptions of the performance comparator groups. In 2017, performance RSUs were granted based on Nucor’s ROE performance for the preceding year. In addition, time-vesting RSUs and stock options were granted in 2017.

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. The Committee may not exercise discretion to increase a payout. For 2017, the Committee reviewed the payouts and determined that the incentive plan payouts were appropriate and, therefore, did not reduce the incentive plan payouts.

COMPENSATION DISCUSSION AND ANALYSIS

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 We Do		What We Don’t Do
✓	Place a heavy emphasis on variable compensation	x	Provide “single trigger” change in control severance benefits
✓	Require significant stock ownership and holding requirements	x	Offer significant perquisites
✓	Subject incentive compensation to a clawback policy	x	Pay excise tax gross ups upon a change in control
✓	Conduct annual compensation risk assessments	x	Permit hedging or short selling of Company stock
✓	Use an independent compensation consultant	x	Change plan designs very often

WHAT GUIDES OUR PROGRAM

Program Aligned with Strategy

Nucor’s executive compensation program supports the Company’s five drivers to profitable growth strategy while maintaining our commitment to safe and environmentally responsible operations:

1. Strengthen our position as a low-cost producer;

2. Achieve market leadership positions in every product line in our portfolio;

3. Move up the value chain by expanding our capabilities to produce higher-quality, higher-margin products;

4. Expand and leverage our downstream channels to market to increase our steel mills’ baseload volume for sustained results; and

5. Achieve commercial excellence to complement our traditional operational strength.

Our 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 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:

Key Principle	Description
Pay for Performance	A significant portion of total compensation should be variable and dependent upon the attainment of certain specific and measurable annual and long-term performance objectives.
Attraction and Retention	The executive compensation program should enable the Company to attract highly-talented people with exceptional leadership capabilities and retain high-caliber talent.
Team-Based Incentives	All of Nucor’s incentives are team-based. Across the organization, Nucor teammates win and lose together. When Nucor performs well, all teammates earn more. When our performance is less than expected, our teammates earn less. Our pay programs support our team-based culture.
Stockholder Alignment	Executive Officers should be compensated through pay elements (base salaries and annual and long-term incentives) designed to create long-term value for our stockholders and reinforce a strong culture of ownership.

    2018 Proxy Statement    25

COMPENSATION DISCUSSION AND ANALYSIS

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

Compensation Element	Form	Description
Base Salary	Cash (Fixed)	Provides a guaranteed rate of pay commensurate with an Executive Officer’s job scope, level of responsibilities, experience and tenure, but set below the market median of similar positions at industrial and materials companies.
Annual Incentives	Cash (Variable)	Provides Executive Officers an opportunity to receive annual cash incentive awards based on Nucor’s annual ROE and ROAIC.
Long-Term Incentives	Equity (mix of Fixed and Variable) and Cash (Variable)	Rewards performance over multi-year periods and growth in long-term stockholder value.

These compensation elements provide a balanced mix of guaranteed compensation and variable, at-risk compensation with an emphasis on annual and long-term incentives. The Committee annually considers adjustment 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.

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 to set base salaries below the market median.

For purposes of setting the 2017 base salary levels for the Executive Officers other than the Chief Executive Officer and the Chief Financial Officer, the Committee referred to the Pearl Meyer Executive Officer compensation benchmarking completed in 2015. For purposes of setting the 2017 base salary levels for the Chief Executive Officer and the Chief Financial Officer, the Committee reviewed information from the 2015 benchmarking that was aged to the end of 2016.

In 2015, Pearl Meyer, at the direction of the Committee, benchmarked Nucor’s compensation against the 28 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.

26         2018 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS

* Since the 2015 benchmarking, E.I. du Pont de Nemours and Company and Tyco International Ltd. have been acquired and removed from the peer group.

Some of the above 28 companies are included in the Steel Comparator Group or the General Industry Comparator Group used in the incentive plans as described below. However, these 28 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 many 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 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.

The performance comparator groups for performance periods that began in 2017 are comprised of the following companies:

Comparator Group	Criteria	Who They Are
Steel	›  Must be a group of not less than five steel industry competitors; and ›  Competitors defined as companies with product offerings similar to Nucor’s.	•  AK Steel Holding Corporation •  Commercial Metals Company •  Steel Dynamics, Inc. •  TimkenSteel Corporation* •  United States Steel Corporation
General Industry	›  Must be a group of not less than 10 companies in capital-intensive industries; and ›  Are well-respected, capital-intensive companies that have performed well over a long period of time.	•  3M Company •  Caterpillar Inc. •  Cummins Inc. •  Emerson Electric Co.** •  General Dynamics Corporation	•  Illinois Tool Works Inc. •  Johnson Controls International plc •  Parker-Hannifin Corporation •  PPG Industries, Inc. •  United Technologies Corporation

* Worthington Industries, Inc. was dropped from the Steel Comparator Group and TimkenSteel Corporation was added for 2017. Worthington is primarily a steel processor while TimkenSteel is a steel manufacturer.

** The Dow Chemical Company was dropped from the General Industry Comparator Group (due to its 2017 merger with DuPont) and Emerson Electric Co. was added for 2017.

COMPENSATION DISCUSSION AND ANALYSIS

2017 EXECUTIVE COMPENSATION IN DETAIL

Determination of 2017 Compensation

In making its determinations with respect to executive compensation for 2017, the Committee was supported by A. Rae Eagle, Nucor’s General Manager and Corporate Secretary, and Donovan E. Marks, Nucor’s General Manager of Human Resources. 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 Chief Executive Officer and other Executive Officers. Pearl Meyer also was retained to assist the Committee with additional projects, including benchmarking Executive Officer compensation, benchmarking executive and non-employee director compensation, reviewing and developing alternatives for the performance comparator groups, 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 General Manager of Human Resources and the General Manager and Corporate Secretary 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 Chief Executive Officer 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. Ferriola, as Chief Executive Officer, to be present at Committee meetings where executive compensation and Company performance were discussed and evaluated. Mr. Ferriola 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 Chief Executive Officer to discuss his compensation, but the Committee made decisions regarding Mr. Ferriola’s compensation in executive session, based solely upon the Committee’s deliberations. The Committee’s decisions regarding the compensation of other Executive Officers were made after considering recommendations from the Chief Executive Officer.

Base Salary

The Committee’s goal is to set Executive Officers’ base salaries below the median base salary level for comparable positions at industrial and materials companies. The Committee sets base salaries below the median because of the Committee’s desire to orient the Executive Officers’ total pay significantly towards variable, at-risk incentive compensation. Base salaries for 2017 were as follows:

Executive Officer	2017 Base Salary		2016 Base Salary		% Change
John J. Ferriola	$	1,365,000	$	1,300,000		5	%
James D. Frias	$	519,600	$	490,350		6	%
James R. Darsey	$	472,350	$	463,100		2	%
Ladd R. Hall	$	472,350	$	463,100		2	%
R. Joseph Stratman	$	498,600	$	488,800		2	%

Mr. Ferriola’s base salary adjustment reflected the Committee’s continuing commitment to bring the Chief Executive Officer’s salary closer to, but still below, the median of the aged benchmark data. After the adjustment, Mr. Ferriola’s 2017 base salary was near but still below the median of the aged benchmark data (by approximately 1%). Mr. Frias’ base salary adjustment also reflected his base salary being materially below the median of the aged benchmark data. Mr. Darsey, Mr. Hall and Mr. Stratman all received a 2% base salary increase consistent with the range of base salary adjustments for other Nucor executives.

COMPENSATION DISCUSSION AND ANALYSIS

Annual Incentives

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

An Executive Officer may earn an incentive award under the AIP for each year of up to a maximum of 300% of the Executive Officer’s base salary, as follows:

• Seventy-five percent (75%) of the maximum incentive award or 225% of base salary (75% of 300% = 225%) is earned based on Nucor’s ROE. For 2017, the Committee set the threshold at 3% ROE and the maximum at 20% ROE. The threshold level of ROE is set by the Committee on an annual basis. If Nucor achieves the threshold ROE, the Executive Officer will earn an incentive award equal to 20% of his base salary. If Nucor’s ROE for the year is 20% or higher, the Executive Officer will earn an incentive award equal to the maximum 225% of his base salary. A prorated incentive award is earned for ROE between 3% and 20%.

• The remaining 25% of the maximum annual award available under the AIP or up to 75% of the Executive Officer’s base salary (25% of 300% = 75%) is earned based on Nucor’s annual ROAIC compared to the annual ROAIC of members of the Steel Industry Comparator Group (identified above) as follows:

Steel Comparator Group Rank (1)	Percentage of Performance Award Opportunity	Performance Award Payment (% of Base Salary)
1	100%	75%
2	80%	60%
3	60%	45%
4	40%	30%
5	20%	15%
6	0%	0%

(1) The table represents potential AIP awards for 2017 annual ROAIC performance. This portion of the incentive is intended to reward performance against other steel companies. The comparator group for future years may include more comparator companies. The potential awards are adjusted to reflect the number of comparator companies in the group.

For 2017, the Committee changed the second performance metric to ROAIC from revenue growth. After careful consideration, the Committee determined that ROAIC was more aligned with Nucor’s strategy and five drivers to profitable growth including vertical integration, which is not reflected in revenue growth.

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 incentive units in cash within 30 days of when stockholders are paid.

Three Executive Officers, Mr. Frias, Mr. Hall and Mr. Stratman, participate in this deferral program.

COMPENSATION DISCUSSION AND ANALYSIS

2017 Performance Results and AIP Payout

Based on Nucor’s ROE of 15.78% and being ranked first within the Steel Comparator Group based on ROAIC for 2017, Executive Officers earned an award of 174.11% of base salary for the ROE performance measure and an award of 75% of base salary for the ROAIC performance measure. As a result, the total AIP award earned was equal to 249.11% of base salary.

	2017 Base Salary		AIP Award Payout
Executive Officer			Deferred (1)		Paid in Cash		Total
John J. Ferriola	$	1,365,000		—	$	3,400,352	$	3,400,352

R. Joseph Stratman	$	498,600	$	621,031	$	621,031	$	1,242,062

(1) As discussed above, Mr. Frias, Mr. Hall and Mr. Stratman elected to defer a portion of their AIP payout and received additional stock units having a value equal to 25% of their deferred amount.

Long-Term Incentives

Long-term incentives are used to balance the short-term focus of the AIP by rewarding performance over multi-year periods and growth in long-term stockholder value. Executive Officers receive long-term incentives in the following forms:

• Cash and restricted stock through the three-year performance-based awards under the LTIP;

• RSUs that vest over time;

• Performance RSUs that may be granted only if certain levels of ROE are achieved; and

• Stock options.

The Committee believes that one-half of the three-year LTIP awards should be earned relative to performance as compared to the Steel Comparator Group and the other half earned relative to performance as compared to the General Industry Comparator Group. The Committee believes that this plan design provides an incentive to perform better than steel industry competitors, as well as other capital-intensive companies. The Committee also believes it is appropriate to provide a level of retention through time-vesting RSUs, alignment with stockholders through stock options, and an opportunity to earn more RSUs, based on performance, that become vested at retirement.

The Long-Term Incentive Plan

Executive Officers earn incentive compensation under the LTIP based on Nucor’s performance during the LTIP’s performance periods. The performance periods commence every January 1 and last for three years.

30         2018 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS

The target award under the LTIP for each performance period is a number of shares of Nucor common stock. The target number of shares is determined by dividing 85% of each Executive Officer’s annual base salary rate as of the beginning of the performance period by the closing price of Nucor common stock on the last trading day immediately preceding the first day of the performance period. The targets for the performance period beginning January 1, 2015 and ended December 31, 2017 were as follows:

Executive Officer	Base Salary Rate at the Beginning of the Performance Period		85% of Base Salary		Nucor Stock Price 12/31/14		Target Award Number of Shares
John J. Ferriola	$	1,200,000	$	1,020,000	$	49.05		20,795
James D. Frias	$	467,000	$	396,950	$	49.05		8,092
James R. Darsey	$	432,400	$	367,540	$	49.05		7,493
Ladd R. Hall	$	454,000	$	385,900	$	49.05		7,867
R. Joseph Stratman	$	454,000	$	385,900	$	49.05		7,867

The maximum award that an Executive Officer may earn under the LTIP is equal to 200% of the target number of shares.

Fifty percent (50%) of the LTIP award is based on Nucor’s ROAIC for the performance period relative to the Steel Comparator Group based on the table below. The remaining 50% of the award is based on Nucor’s ROAIC for the performance period relative to the General Industry Comparator Group based on the table below.

A maximum award of 200% may be earned if Nucor ranks first relative to the Steel Comparator Group (which earns 100% of target) and ranks first or second relative to the General Industry Comparator Group (which earns an additional 100% of target).

Steel Comparator Group (1)		General Industry Comparator Group (1)
Rank	Award as a % of Target	Rank	Award as a % of Target
1	100%	1 or 2	100%
2	80%	3 or 4	80%
3	60%	5 or 6	60%
4	40%	7 or 8	40%
5	20%	9	20%
6	0%	10 or 11	0%

(1) These tables represent the potential awards based on the LTIP performance period that began January 1, 2017. The comparator group for other performance periods may include more or fewer comparator companies. The potential awards are adjusted to reflect the number of comparator companies in the group.

One-half of each LTIP award is paid in cash and the other half is paid in restricted stock. Restricted stock vests one-third on each of the first three anniversaries of the award date, or upon the Executive Officer’s attainment of age 55, death or disability while employed by Nucor.

An Executive Officer may defer delivery of the restricted stock portion of an LTIP award until the Executive Officer’s retirement or other termination of employment. Nucor does not provide an incentive for the deferral of LTIP restricted stock awards. Dividend equivalents are paid in cash on deferred restricted stock awards within 30 days of when stockholders are paid.

2017 Performance Results and LTIP Payout

Nucor’s ROAIC of 20.25% for the LTIP performance period that began January 1, 2015 and ended December 31, 2017 was ranked second relative to members of the Steel Comparator Group (second out of six) and ranked seventh relative to the General Industry Comparator Group (seventh out of 11).

    2018 Proxy Statement    31

COMPENSATION DISCUSSION AND ANALYSIS

These rankings resulted in the following performance award as a percentage of targets:

Performance Measure	ROAIC			Ranking		Performance Award as a % of Target Number of Shares
ROAIC — Steel Comparator Group		20.25	%		2		80	%
ROAIC — General Industry Comparator Group		20.25	%		7		40	%
Total							120	%

The resulting payouts were as follows:

Executive Officer	Target Award Number of Shares		Performance Award as a % of Target			Shares Earned
John J. Ferriola		20,795		120	%		24,954
James D. Frias		8,092		120	%		9,710
James R. Darsey		7,493		120	%		8,991
Ladd R. Hall		7,867		120	%		9,440
R. Joseph Stratman		7,867		120	%		9,440

Nucor paid one-half of the LTIP award in cash and the other half in the form of restricted shares of Nucor’s common stock in March 2018.

Restricted Stock Units

The Committee believes that RSUs align Executive Officers’ interests with those of stockholders and provide significant retentive characteristics. Each June 1, a base amount of RSUs is granted to each Executive Officer. One-third of the base amount of RSUs becomes vested on each of the first three anniversaries of the June 1 award date, upon the Executive Officer’s retirement (defined below), or upon the Executive Officer’s death or disability while employed by Nucor.

Performance RSUs are granted contingent on Nucor’s ROE for the prior year. Performance RSUs vest upon the Executive Officer’s retirement, death or disability while employed by Nucor. Performance RSUs must be held as long as the participant is employed by Nucor. Performance RSUs are forfeited if the Executive Officer leaves employment other than due to retirement, death or disability. The threshold ROE required for a grant of performance RSUs is 3%. The maximum number of performance RSUs is granted for ROE of 20% or more.

The total number of RSUs granted is determined for each Executive Officer position by dividing the dollar amount shown below (prorated for ROE between any of the levels shown below) by the closing price of Nucor’s common stock on the annual June 1 grant date.

The size of base grants is determined based on the Executive Officer’s position on the grant date. The size of performance RSU grants is determined based on the Executive Officer’s position as of May 31 of the performance year (2016 in the present case). In 2017, a new grant level was added when Nucor created the position of Chief Digital Officer and Executive Vice President. The following schedule was effective for grants on June 1, 2017:

	Base RSUs Market Value		Performance RSUs Market Value (Based on Prior Fiscal Year ROE)
Position			3% ROE		10% ROE		12.5% ROE		15% ROE		20% ROE
Chairman, Chief Executive Officer and President	$	1,000,000	$	750,000	$	1,100,000	$	1,500,000	$	2,250,000	$	4,600,000
Chief Financial Officer	$	300,000	$	450,000	$	625,000	$	750,000	$	1,530,000	$	2,220,000

2017 Performance Results and RSU Awards

On June 1, 2017, as a result of 2016 ROE of 10.4%, the Executive Officers received base and performance RSUs with the following values:

	Grant Date Value
Executive Officer	Base RSUs		Performance RSUs		Total (1)
John J. Ferriola	$	999,996	$	1,163,974	$	2,163,970

R. Joseph Stratman	$	299,958	$	464,349	$	764,307

(1) The actual number of RSUs granted is rounded down to the nearest full unit.

Stock Options

On June 1, 2017, the Committee granted options to each Executive Officer in the amounts shown in the table below with the following grant values:

Position	Grant Date Value of Options (1)
Chairman, Chief Executive Officer and President	$	4,000,000
Chief Financial Officer	$	600,000
Chief Digital Officer	$	600,000
Executive Vice Presidents	$	600,000

(1) The actual number of stock options granted is rounded down to the nearest full option.

The options vest on the third anniversary of the grant date or upon the Executive Officer’s death, disability or retirement (same as RSUs above) and have a 10-year term.

OTHER PRACTICES, POLICIES AND GUIDELINES

Stock Ownership Guidelines

Executive Officers have an opportunity to earn a significant number of Nucor shares and the Committee considers executive stock ownership a key element of the Nucor culture. Executive Officers are required to hold a significant number of shares as outlined below:

Chairman, Chief Executive Officer and President	At least 150,000 shares
Chief Financial Officer	At least 50,000 shares
Chief Digital Officer	At least 50,000 shares
Executive Vice Presidents	At least 50,000 shares

The above guidelines are higher than the median guidelines for Nucor’s steel company peers and other industrial and materials companies of similar size.

    2018 Proxy Statement    33

COMPENSATION DISCUSSION AND ANALYSIS

All Executive Officers were in compliance with the stock ownership guidelines as of December 31, 2017. Executive Officers have five years to achieve ownership of the guideline number of shares. On an annual basis, the Committee monitors each Executive Officer’s compliance with the ownership guideline or, if applicable, the Executive Officer’s progress in achieving ownership of the guideline number of shares. If the Committee determines an Executive Officer is not in compliance or has not made sufficient progress toward achieving the ownership guideline, the Committee has the discretion to take action or adjust incentive award payments to concentrate payouts more heavily in Nucor common stock.

Executive Officers have significant exposure to Nucor’s stock price through direct stock ownership and their target LTIP awards. The Committee believes aligning the long-term interests of Executive Officers with the long-term interests of Nucor’s stockholders in a material way promotes superior long-term performance. It also means that if Nucor’s stock price declines, then Executive Officers’ Nucor stock, options, LTIP awards and RSUs all decline in value.

No Hedging or Short Selling

Nucor maintains policies that apply to all officers, certain designated employees and the members of the Board that prohibit hedging or short selling (profiting if the market price of the securities decreases) of Nucor securities.

Executive Officer Incentive Compensation Recoupment (“Clawback”) Policy

The Company has a written policy to address the recoupment of performance-based compensation awarded to or earned by an executive officer if there is a restatement of the Company’s financial results due to material noncompliance of the Company with any financial reporting requirement under the federal securities laws. In the event of such a restatement, the Committee shall review the performance-based compensation awarded to or earned by the executive officers for the three-year period prior to the restatement event and, if the Committee determines in its reasonable discretion that any such performance-based compensation would not have been awarded to or earned by an executive officer based on the restated financial results, the Committee shall within 12 months of the restatement event, to the extent practicable, seek to recover from such executive officer any portion of the performance-based compensation that is greater than that which would have been awarded or earned had it been calculated on the basis of the restated financial results.

Benefits

Executive Officer benefits are limited to benefits provided to all other full-time employees on the same basis and at the same cost as all other full-time employees. Nucor does not provide any tax gross ups. Certain benefits such as Nucor’s Profit Sharing, Scholarship Program, Employee Stock Purchase Plan, Extraordinary Bonus and Service Awards Program are not available to Nucor’s Executive Officers.

Changes Effective in 2018

During 2017, the Committee, with the help of management and Pearl Meyer, its independent compensation consultant, reviewed executive compensation levels, incentive plan metrics, sensitivity to performance (including relative pay at various levels of potential performance) and performance comparator groups. The purpose of this exercise was to ensure Nucor’s executive compensation plans continue to be aligned with the Company’s compensation philosophy.

The review provided the Committee insight into how Nucor’s incentive plans have performed relative to the steel and general industry comparator groups and the compensation benchmark companies. In general:

• Nucor’s pay has been well-aligned with Nucor’s performance.

• Nucor’s incentive plan metrics and comparator groups support Nucor’s compensation philosophy and five drivers to profitable growth.

• Nucor’s annual performance has generally been higher than steel peers but Nucor’s annual payouts as a percent of target have been below steel peers.

34         2018 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS

• As Nucor has grown, the LTIP (which pays for performance relative to steel and general industry comparators) has become a smaller percent of total compensation.

The Committee is reviewing the above work and considering changes for 2018.

Post-Termination Compensation Benefits

The Committee believes that Executive Officers should be provided a reasonable severance benefit in the event an executive is terminated. Severance benefits for Executive Officers reflect the fact that it may be difficult to find comparable employment within a reasonable period of time. The Committee periodically reviews total compensation, including these post termination compensation benefits, to ensure that such amounts remain reasonable.

Non-Compete and Non-Solicitation Agreements.    Nucor has entered into a non-compete and non-solicitation agreement with each Executive Officer. Pursuant to these agreements, the Executive Officers have agreed not to compete with Nucor during the 24-month period following their termination of employment with Nucor for any reason in exchange for monthly cash payments from Nucor during the non-competition period. The agreements with the Executive Officers also restrict the disclosure of confidential information and prohibit the Executive Officers from encouraging Nucor customers to purchase steel or steel products from any Nucor competitor or encouraging any Nucor employee to terminate his or her employment with Nucor. Each agreement further provides that any inventions, designs or other ideas conceived by the Executive Officers during their employment with Nucor will be assigned to Nucor. Since Nucor began entering into the non-compete and non-solicitation agreements with its executive officers in 1999, no executive officer has left Nucor other than to retire.

The amount of each monthly cash payment during the 24-month non-competition period will be equal to the product of 3.36 times the Executive Officer’s highest annual base salary during the 12 months immediately preceding the termination of his employment, divided by 12. If an Executive Officer who is receiving monthly installment payments dies within 12 months of his date of termination of employment, Nucor will continue to pay his estate the monthly payments only through the end of the first 12 months following termination of his employment. Nucor’s obligation to make the monthly installment payments to an Executive Officer terminates if the Executive Officer dies 12 or more months following termination of his employment.

Severance Benefits.    Executive Officers are entitled to receive severance payments following termination of employment or their resignation, death or retirement under the Severance Plan for Senior Officers and General Managers. The amount of severance payments to be received by a particular Executive Officer or, in the case of his death while employed by Nucor, his estate, will depend upon his age at the time of his termination, resignation, retirement or death and his length of service with Nucor. If the Executive Officer is younger than age 55, then the Executive Officer, or his estate, will be entitled to receive a severance payment equal to the greater of (i) one month of his base salary for each year of service to Nucor with a minimum severance payment of six months’ base salary or (ii) the value of the total number of his unvested shares of Nucor common stock (including deferred shares) granted under the LTIP. If the Executive Officer is age 55 or older, then the Executive Officer, or his estate, will be entitled to receive a severance payment equal to one month of his base salary for each year of service to Nucor with a minimum severance payment of six months’ base salary.

Change in Control Benefits.    Nucor provides Executive Officers the following benefits in the event of a change in control of Nucor. The benefits do not result in Executive Officers receiving severance benefits in excess of three times their annual compensation or provide an excise tax gross up for any payments that would be considered excess parachute payments under Section 280G of the Internal Revenue Code.

• Severance – If terminated within 24 months of a change in control, Executive Officers participating in Nucor’s severance plan would receive a severance payment equal to a base amount multiplied by 3 in the case of the Chief Executive Officer, 2.5 in the case of the Chief Financial Officer, and 2 in the case of any other Executive Vice President. The base amount is the sum of the executive’s base salary plus the greater of target or the three-year average actual award under the AIP, plus the greater of target or the most recent award under the LTIP. The target awards under the AIP and the LTIP are equal to 50% of each plan’s maximum award payout. In addition, Executive Officers participating in Nucor’s severance plan would receive 36 months of medical, dental and life insurance continuation for the Chief Executive Officer, 30 months for the Chief Financial Officer and 24 months for all other Executive Officers.

    2018 Proxy Statement    35

COMPENSATION DISCUSSION AND ANALYSIS

• Annual Incentive Plan – For the year in which a change in control occurs, the AIP award will be no less than an award equal to the greater of actual performance through the change in control or target performance, in each case prorated through the date of the executive’s termination of employment.

• Long-Term Incentive Plan – The LTIP performance periods in progress on the date of the change in control will be terminated and awards will be paid based on a prorated basis through the date of the change in control in an amount equal to the greater of actual or target performance.

• Acceleration of Unvested Equity – All unvested equity awards under the AIP and the LTIP, including deferred shares, and all outstanding unvested options and RSUs, will vest upon a change in control.

• Restricted Stock Units – If terminated within 24 months of a change in control, Executive Officers would receive a payment equal to the sum of the value of the RSUs that would have been granted in the year of termination based on the prior year’s performance (if not granted prior to the date of termination) and the value of the RSUs that would normally be granted the following year for performance during the year of the Executive Officer’s termination.

• Excess Parachute Payments – If any payments or benefits would be considered excess parachute payments under Section 280G of the Internal Revenue Code, the payments or benefits would be reduced to the Section 280G safe harbor amount if the reduction results in a larger net benefit to the Executive Officer. Executive Officers are responsible for taxes on all payments. No tax gross ups are provided.

(1) Represents RSUs awarded June 1, 2017 under the 2014 Plan.

(2) The Executive Officers were eligible to earn a range of performance-based payments under the AIP for the Company’s performance during 2017. The threshold and maximum amounts shown are equal to 15% and 300%, respectively, of each Executive Officer’s base salary. While the AIP does not have a stated target amount, the Committee uses 150% as the target for its compensation decisions.

(3) Represents the range of performance-based awards that may be earned under the LTIP for the 2017-2019 performance period. Earned awards, if any, will be paid one-half in cash and the other half in the form of restricted shares of Nucor’s common stock in March 2020. The grant date fair value is calculated by multiplying the closing price of Nucor common stock on the grant date by the target number of shares.

(4) Represents stock options awarded June 1, 2017 under the 2014 Plan.

(5) The awards have been valued using the June 1, 2017 closing price of Nucor common stock of $59.07.

(6) The target awards have been valued using the December 31, 2016 closing price of Nucor common stock of $59.52.

(7) The awards have been valued using a Black-Scholes value of $12.61.

(8) Represents common stock units deferred under the 2017 AIP. The awards were paid in March 2018.

(9) The awards have been valued using the March 9, 2018 closing price of Nucor common stock of $67.16.

Non-Equity Incentive Plan Awards

Under the AIP, Executive Officers may earn a non-equity incentive award for each year of up to a total of 300% of the Executive Officer’s base salary. For a description of the AIP, please refer to the “2017 Executive Compensation in Detail – Annual Incentives” section of this CD&A beginning on page 29. While the AIP has no stated target, for planning purposes including compensation benchmarking, the Committee considers target to be 50% of the maximum.

COMPENSATION DISCUSSION AND ANALYSIS

Equity Incentive Plan Awards

Restricted Stock Units

Each year, on or about June 1, participants are granted a threshold or base amount of RSUs. An additional amount of RSUs may be granted based on Nucor’s ROE for the prior year. The base award vests annually over the three-year period following the date of grant or upon retirement. The ROE-based award vests at retirement. The RSUs were granted on June 1, 2017 and are reported in column (i).

Stock Options

The Committee granted the Executive Officers options to purchase shares of Nucor common stock at an exercise price of $59.07. The options become vested and exercisable on June 1, 2020.

Long-Term Incentive Plan

The range of potential grants for the performance period January 1, 2017 through December 31, 2019 is reported in columns (f), (g) and (h). The Company pays one-half of the LTIP award in cash and the other half in the form of restricted shares of Nucor’s common stock. The number of shares is determined at the beginning of the performance period. For a description of the LTIP, please refer to the “2017 Executive Compensation in Detail – Long-Term Incentives” section of this CD&A beginning on page 30.

Actual performance for the LTIP performance period ended December 31, 2016 resulted in cash payments and awards of restricted shares on March 10, 2017 as follows:

	Shares Issued (#)		Cash Paid ($)
John J. Ferriola		7,563		450,191
James D. Frias		3,395		202,112
James R. Darsey		3,187		189,744
Ladd R. Hall		3,526		209,884
R. Joseph Stratman		3,526		209,884

All of the Executive Officers were 55 or older as of March 10, 2017; therefore, the restricted shares vested upon issuance. These shares were granted at the beginning of the performance period, January 1, 2014, and are therefore not reported in the Grants of Plan-Based Awards Table for 2017.

Nonqualified Deferred Compensation Table

The table below presents information about the amounts deferred by the Executive Officers under the AIP. 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 incentive units in cash within 30 days of when stockholders are paid.

COMPENSATION DISCUSSION AND ANALYSIS

(7) Represents 20,605 deferred units valued using the closing price of Nucor common stock of $63.58 on December 31, 2017. Of the amount shown, $1,076,402 was reported in the Summary Compensation Tables of Nucor proxy statements for previous years.

Internal Revenue Code Section 162(m)

Internal Revenue Code Section 162(m) limits the amount of compensation paid to certain Executive Officers that may be deducted by Nucor for federal income tax purposes in any year to $1,000,000. “Performance-based” compensation that has been approved by Nucor’s stockholders is not subject to the $1,000,000 deduction limit. Nucor’s incentive plans have all been approved by Nucor’s stockholders, and awards under those plans, other than certain time-vesting RSUs, should constitute “performance-based” compensation that is not subject to the Section 162(m) deduction limit. The Committee has not adopted a formal policy that all compensation paid to Executive Officers must be deductible.

Effective for tax years beginning after December 31, 2017, U.S. tax law changes will expand the definition of covered employees under Section 162(m) to include, among others, the Chief Financial Officer, and eliminate the performance-based compensation exception beginning in 2018. At this time, it is not certain that our performance-based compensation for periods prior to 2018 will qualify for an exemption from the deduction limit under transition relief applicable to arrangements in place as of November 2, 2017.

The Committee views the tax deductibility of executive compensation as one factor to be considered in the context of its overall compensation philosophy, and will consider the tax law changes. The Committee reviews each material element of compensation on a continuing basis to determine whether deductibility can be accomplished without sacrificing flexibility and other important elements of the overall executive compensation program.

Pay Ratio Disclosure

SEC rules require that we provide a comparison of the annual total compensation of John J. Ferriola, our Chief Executive Officer in 2017, to the median of the annual total compensation of our employees other than Mr. Ferriola. For purposes of providing the comparison in accordance with SEC rules, we identified a “median employee” and compared Mr. Ferriola’s annual total compensation to that of the median employee. For 2017, our last completed fiscal year:

• Mr. Ferriola’s annual total compensation was $12,090,472.

• Our median employee’s annual total compensation was $90,635.

• The ratio of Mr. Ferriola’s annual total compensation to our median employee’s annual total compensation was 133 to 1.

The methodology that we used to identify the median employee is described below. Annual total compensation is calculated in the same manner as the amount set forth in the “Total” column in the Summary Compensation Table. While, as explained below, the methodology involves several assumptions and adjustments, we believe the pay ratio information set forth above constitutes a reasonable estimate, calculated in a manner consistent with applicable SEC rules.

Because other companies may use different methodologies to identify their median employees, the pay ratio set forth above may not be comparable to the pay ratios reported by other companies.

Methodology

Date Used to Determine Employee Population.    For purposes of identifying the median employee, we selected October 1, 2017 to be the date as of which we would determine our employee population.

Composition of Employee Population.    We determined that, as of October 1, 2017, we had 25,322 employees globally. Of that amount, 22,672 were U.S. employees and 2,650 were non-U.S. employees. In order to simplify the determination of the median employee and as permitted by SEC rules, we excluded 292

    2018 Proxy Statement    43

COMPENSATION DISCUSSION AND ANALYSIS

non-U.S. employees (approximately 1.2% of our employees) located in seven countries, comprising all of the employees in those countries, as set forth in the table below:

Country Excluded	Number of Employees Excluded
China	4
India	215
Mexico	22
Poland	2
Sri Lanka	38
Switzerland	10
United Arab Emirates	1

After excluding the 292 non-U.S. employees, we determined the identity of our median employee from a population of 25,030 employees, including 22,672 U.S. employees and 2,358 non-U.S. employees.

Given availability of payroll data, the size, composition and global diversity of these 25,030 employees, we employed statistical sampling to assist in identification of the median employee. We stratified the employee population based on similarity of characteristics such as product line and geography into groups. We then took the natural log of compensation data for each employee within the group. From the lognormal data, we calculated median, standard deviation and variance of each group for the purposes of deriving sample sizes that fairly represented the grouping. Using this methodology, we generated a random sample of 4,464 employees. The group medians were then weighted by total group headcount relative to Nucor’s 25,030 employees to derive the median employee.

As permitted by SEC rules, the employee population data described above does not include approximately 122 employees of St. Louis Cold Drawn, Inc., an entity we acquired in September 2017.

Pay Data Used.    To identify the median employee, we derived compensation information from our payroll records for fiscal 2017. We used a consistently applied compensation measure (CACM) which included total taxable income, or equivalent. We converted the amount of compensation paid to non-U.S. employees to U.S. dollars using average foreign currency exchange rates for 2017. We annualized compensation for employees hired during 2017.

The employee whose CACM was at the median of the employee population, determined as described above, is the “median employee” for purposes of the comparison to Mr. Ferriola’s annual total compensation.

PROPOSAL 3

ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

The Board of Directors recommends a vote FOR the resolution.

As required by Section 14A of the 1934 Act, Nucor is requesting stockholder approval of the compensation of its Executive Officers in 2017, which is described in the “Compensation Discussion and Analysis” section, compensation tables and related narrative discussion of this Proxy Statement. This approval is not intended to address any specific item or element of compensation or the compensation of any particular Executive Officer, but rather the overall compensation of the Company’s Executive Officers and the philosophy, principles and policies used to determine compensation.

Stockholders were most recently asked to approve the compensation of Nucor’s Executive Officers at the Company’s 2017 annual meeting of stockholders, and stockholders approved the Company’s Executive Officer compensation with more than 95% of the votes cast in favor. At the 2017 annual meeting of stockholders, the Company’s stockholders were also asked to indicate whether future advisory stockholder votes on Executive Officer compensation should occur every one, two or three years. Based on the voting results, the Board adopted a policy that the Company will include an advisory stockholder vote on Executive Officer compensation in the Company’s proxy materials on an annual basis until the next required advisory vote on the frequency of advisory stockholder votes on Executive Officer compensation, which will occur no later than the Company’s annual meeting of stockholders in 2023.

As described in the “Compensation Discussion and Analysis” section, compensation for all employees at Nucor, including Executive Officers, is performance-based. Nucor pays for results. The executive compensation program is designed to pay above the market median when performance is outstanding and, conversely, to pay below the market median when performance is below Nucor’s peers. This is accomplished through a compensation program for Executive Officers that is balanced but highly leveraged — a significant portion of each Executive Officer’s potential compensation is variable and based on results achieved. Executive Officer compensation is earned under incentive plans that are based on Nucor’s performance and the value delivered to its stockholders. Stock ownership requirements and the design of the long-term incentives ensure that Executives Officers are significantly exposed to Nucor’s financial performance and changes in stock price, thereby aligning their interests with stockholders’ interests.

The Compensation and Executive Development Committee of the Board (“the Committee”) monitors and reviews the compensation program to ensure that it continues to support Nucor’s unique culture, including its ability to attract, retain and motivate its workforce. The Committee also regularly reviews the program to ensure that it is not reasonably likely to incentivize Executive Officers to take risks that could have a material adverse impact on Nucor. Stockholders are urged to read the “Compensation Discussion and Analysis” section, along with the compensation tables and the related narrative discussion, which more thoroughly discuss the Company’s compensation policies and procedures. The Committee and the Board believe that these policies and procedures are effective in implementing the Company’s overall compensation philosophy.

This vote is an advisory vote, which means that the stockholder vote on this proposal will not be binding on Nucor, the Committee or the Board, nor will it create or imply any change in the fiduciary duties of, or impose any additional fiduciary duty on, Nucor, the Committee or the Board. However, the Committee values the opinions expressed by Nucor’s stockholders and will carefully consider the outcome of the vote when making future compensation decisions for Nucor’s Executive Officers.

Vote Recommendation

The Board of Directors recommends a vote FOR the below advisory resolution approving the compensation paid to Nucor’s Executive Officers in 2017. Unless otherwise specified, proxies will be voted FOR the resolution.

RESOLVED, that the compensation paid to Nucor’s Executive Officers, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC, including the “Compensation Discussion and Analysis” section, compensation tables and related narrative discussion included in this Proxy Statement, is hereby APPROVED.

PROPOSAL 4

STOCKHOLDER PROPOSAL

We have been notified that Domini Impact Equity Fund (the “Fund”) intends to present the proposal set forth below for consideration at the Annual Meeting. The address and number of shares of the Company’s common stock held by the Fund will be promptly provided upon oral or written request made to our Corporate Secretary. We are not responsible for the content of the stockholder proposal, which is printed below exactly as it was submitted.

The Board of Directors recommends a vote AGAINST this stockholder proposal. Unless otherwise specified, proxies will be voted AGAINST the proposal.

Political Lobbying Report

Whereas, we believe in full disclosure of Nucor’s direct and indirect lobbying activities and expenditures to assess whether Nucor’s lobbying is consistent with its expressed goals and in the best interests of stockholders.

Resolved, the stockholders of Nucor request the preparation of a report, updated annually, disclosing:

1. Company policy and procedures governing lobbying, both direct and indirect, and grassroots lobbying communications.

2. Payments by Nucor used for (a) direct or indirect lobbying or (b) grassroots lobbying communications, in each case including the amount of the payment and the recipient.

3. Nucor’s membership in and payments to any tax-exempt organization that writes and endorses model legislation.

4. Description of management’s and the Board’s decision making process and oversight for making payments described in sections 2 and 3 above.

For purposes of this proposal, a “grassroots lobbying communication” is a communication directed to the general public that (a) refers to specific legislation or regulation, (b) reflects a view on the legislation or regulation and (c) encourages the recipient of the communication to take action with respect to the legislation or regulation. “Indirect lobbying” is lobbying engaged in by a trade association or other organization of which Nucor is a member.

Both “direct and indirect lobbying” and “grassroots lobbying communications” include efforts at the local, state and federal levels.

The report shall be presented to the Audit Committee or other relevant oversight committees and posted on Nucor’s website.

Supporting Statement

As stockholders, we encourage transparency and accountability in the use of corporate funds to influence legislation and regulation. Nucor spent $13,610,000 from 2010 — 2016 on federal lobbying. Data on state level spending is not consistently available. Nucor spent $555,606 on lobbying in North Carolina from 2010 — 2016. Nucor’s lobbying over steel tariffs has attracted media attention (“Trump Still Determined to Enact Steel Tariffs, Says Nucor CEO,” Bloomberg, September 29, 2017).

Nucor sits on the board of the National Association of Manufacturers, which spent $25.44 million on lobbying in 2015 and 2016. Nucor also sits on boards of the American Iron and Steel Institute (“AISI”) and the World Steel Association. Nucor does not disclose its trade association memberships, nor payments and the portions used for lobbying. And Nucor does not disclose its membership in or payments to tax-exempt organizations that write and endorse model legislation, such as supporting the Heartland Institute and the American Legislative Exchange Council (ALEC).

We are concerned that Nucor’s lack of trade association and ALEC disclosure presents reputational risks. For example, AISI has drawn media scrutiny for lobbying the EPA (“Scott Pruitt’s EPA Is Letting Industry

    2018 Proxy Statement    47

STOCKHOLDER PROPOSAL

Lobbyists Roll Back Environmental Protections,” Newsweek, October 4, 2017), as has Nucor’s past funding of the Heartland Institute, which has drawn criticism for misleading the public about climate change (“The Steel Magnate Helping Trump Assail Pollution Regulations,” Inside Climate News, August 17, 2016). Over 100 companies have publicly left ALEC, including 3M, Deere, Emerson Electric and International Paper.

Board of Directors’ Statement in Opposition to the Proposal

The Board of Directors recommends a vote AGAINST this proposal. Although the Board supports transparency and accountability in lobbying and corporate spending on political contributions, we believe that adopting the proposal is unnecessary and would not be in the best interests of Nucor and its stockholders.

We believe that the interests and well-being of Nucor, our stockholders, our employees and our nation mandate our active engagement in the public policy decision-making process. Because our business is subject to extensive regulation at all levels of government, we support legislative and regulatory actions that further Nucor’s long-term business strategies, and we oppose any unreasonable, unnecessary or overly burdensome actions that threaten Nucor’s strategic success. More fundamentally, we believe that only a healthy manufacturing industry can return our country’s economy to a sound footing. For that reason, we actively promote government policies that address the multitude of state, national and international issues that challenge the U.S. manufacturing industry, including trade practices in violation of global trade rules, currency manipulation, and tax and overly burdensome regulatory policies that sap the health and vitality of our manufacturing companies.

Nucor takes a multi-faceted approach to political engagement. First, we utilize our unique industry position to engage in direct outreach efforts to ensure that our country’s citizens and leaders understand the challenges facing our economy, our industry and our Company. Through advertisements, articles and other methods, we provide information and thought leadership to promote an improved grassroots understanding of issues of critical importance. For example, we created a page on our website discussing the importance of our country’s manufacturing economy (located at http://www.nucor.com/voice), which facilitates direct communication with the public at large regarding issues that impact Nucor and our entire country. As appropriate, Nucor also engages in lobbying activities that ensure Nucor’s interests are adequately considered by federal, state and local government leaders. Nucor’s lobbying activities are subject to comprehensive regulation at both the federal and state levels. Federal law requires the filing of regular, detailed reports with the U.S. Senate and the House of Representatives disclosing general and specific lobbying activities that are undertaken on our behalf. Such reports are available to the public at www.senate.gov/legislative/lobbyingdisc.htm and http://lobbyingdisclosure.house.gov. State lobbying activities also are subject to detailed registration and disclosure requirements, and such reports are also publicly available through the applicable state authorities. Nucor is committed to complying with all laws applicable to its lobbying activities.

Second, Nucor contributes to, and maintains memberships in, various trade associations and other organizations that we believe share and will further the goals of Nucor and benefit its stockholders. Such associations and organizations provide both a useful forum for discussing issues of general industry significance and a powerful platform for advocating positions on issues of importance to the members. While associations and organizations in which Nucor is a member may from time to time take positions on issues that are not representative of Nucor’s position, on the whole we believe that Nucor’s membership in such organizations is in the long-term interests of our Company and our stockholders.

The Board opposes the proposal because we believe that existing restrictions imposed, and reports required, by state and federal law together with Nucor’s existing internal compliance and decision-making processes strike the appropriate balance between disclosure of Nucor’s activities and protection of Nucor’s strategic and confidential information. All of Nucor’s lobbying and advocacy activities are managed and overseen by its Public Affairs Department, which ensures not only that such activities comply with applicable law but also that all activities further the long-term interests of Nucor and our stockholders.

We believe that the additional disclosure requested by the Fund could put Nucor at a competitive disadvantage by revealing its long-term business strategies and objectives. Competitors, unions and other parties with interests adverse to Nucor also engage in the political process to further their own business or strategic priorities. The Board believes that unilaterally imposing more stringent disclosure and reporting requirements on Nucor would likely benefit these third parties to the detriment of Nucor and its stockholders.

Solicitation and Expenses

Nucor will bear the cost of soliciting proxies and will reimburse brokerage firms and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for sending proxy materials to stockholders and obtaining their proxies. Nucor has retained the services of Innisfree M&A Incorporated to assist in soliciting proxies from the Company’s stockholders for a fee of $15,000 plus reimbursement of reasonable expenses. In addition to soliciting the proxies by mail and the Internet, certain of the Company’s directors, officers and employees, without compensation, may solicit proxies personally or by telephone, facsimile and e-mail.

The Company will promptly deliver, upon oral or written request, a separate copy of this Proxy Statement and the annual report, or the notice regarding the availability of proxy materials on the Internet, as applicable, to any stockholder residing at an address to which only one copy was mailed. Requests for additional copies of this Proxy Statement, the annual report or the notice and/or requests for multiple copies of the proxy statement, the annual report or the notice in the future should be directed to Nucor’s Corporate Secretary at our principal executive offices, 1915 Rexford Road, Charlotte, North Carolina 28211 and (704) 366-7000.
