Important Notice Regarding the Availability of

Proxy Materials for the Stockholder

Meeting to be Held on May 9, 2008

The proxy statement and annual report to stockholders and the means to vote by Internet are available at http://ww3.ics.adp.com/streetlink/NUE.

PLEASE SIGN, DATE AND PROMPTLY RETURN THE ENCLOSED PROXY CARD

IN THE ENCLOSED ENVELOPE, OR VOTE VIA THE TELEPHONE OR INTERNET.

GENERAL INFORMATION

The enclosed proxy is being solicited by the Board of Directors of Nucor Corporation (“Nucor” or the “Company”) for use at the 2008 annual meeting of stockholders to be held on Friday, May 9, 2008, and any adjournment or postponement. The proxy may be revoked by the stockholder by letter to the Nucor Corporate Secretary received before the meeting, or by attending and voting at the meeting.

Shares Entitled to Vote

The record date for the annual meeting is March 11, 2008. Only holders of record of Nucor’s common stock at the close of business on that date will be entitled to vote. The presence in person or by proxy of the holders of a majority of the votes entitled to be cast at the annual meeting is necessary to constitute a quorum. As of the record date for the annual meeting, 288,405,023 shares of Nucor common stock were outstanding.

Voting Rights and Procedures

Each share of 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 common stock is entitled to cumulative voting rights, which means that when voting for nominees for director, each share is entitled to a number of votes equal to the number of nominees for election as directors. Accordingly, when voting for nominees for director, all of the votes a share of common stock is entitled to may be voted in favor of one nominee or the votes 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 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 Item

Election of Directors.    The two director nominees receiving the highest number of all votes cast for directors will be elected. A properly submitted proxy marked “Vote Withheld” with respect to the election of one or more director nominees will not be voted with respect to the director or directors indicated, although it will be counted for purposes of determining whether there is a quorum. Accordingly, any shares not voted with respect to a director nominee will have no effect.

Nucor’s Board of Directors has adopted a Corporate Governance Principle intended to give further effect to withheld votes in uncontested elections for directors under certain circumstances. This Corporate Governance Principle is set forth in this proxy statement under the heading “Election of Directors.”

Other Items.    For any other item, the affirmative vote of a majority of the votes represented in person or by proxy and entitled to vote on the item will be required for approval. A properly submitted proxy marked “Abstain” with respect to any such matter will not be voted, although it will be counted for purposes of determining whether there is a quorum. Accordingly, an abstention will have the effect of a negative vote.

Under current New York Stock Exchange (“NYSE”) rules, the proposals to elect directors and ratify the independent registered public accounting firm are considered “discretionary” matters. This means that brokerage firms may vote in their discretion on these matters on behalf of clients who have not furnished voting instructions.

In contrast, the proposal to approve the senior officers incentive compensation plans and the stockholder proposal are “non-discretionary” matters. This means brokerage firms that have not received voting instructions from their clients on these matters may not vote on these proposals. These “broker non-votes” will not be considered in determining the number of votes necessary for approval and, therefore, will have no effect on the outcome of the vote for these proposals.

Shares held of record by a broker or its nominee (“broker shares”) that are voted on any matter will be included in determining whether a quorum is present. Broker shares that are not voted will not be included in determining whether a quorum is present.

2

Voting of Proxies

The shares represented by each proxy you properly submit to us will be voted by one of the individuals indicated on the proxy as you direct. If you submit a proxy but do not indicate how you wish to vote, your shares will be voted FOR the election of the two director nominees, FOR the ratification of PricewaterhouseCoopers LLP as Nucor’s independent registered public accounting firm for the year ending December 31, 2008, FOR the approval of the annual and long-term senior officers incentive compensation plans and AGAINST the approval of the stockholder proposal.

Delivery of Proxy Materials and Annual Report

The 2007 annual report of Nucor, including financial statements, is being mailed to all stockholders of record together with this proxy statement and form of proxy on or about March 27, 2008.

PROPOSAL 1

ELECTION OF DIRECTORS

Nucor’s Board of Directors is divided into three classes with two or three directors serving in each class. Each director serves for a three-year term with one class of directors being elected at each annual meeting. All directors will hold office until their successors have been duly elected and qualified. Our Board of Directors has affirmatively determined that each director, other than Daniel R. DiMicco, has no material relationships with Nucor (other than as directors) and is “independent” within the meaning of the NYSE’s current listing standards.

The terms of two directors, Peter C. Browning and Victoria F. Haynes, will expire at this annual meeting. The Board’s Governance and Nominating Committee has recommended and the Board of Directors has nominated Mr. Browning and Dr. Haynes for reelection for three-year terms ending at the annual meeting in 2011. Shares represented by all proxies received by the Board of Directors and not marked to withhold authority to vote for these nominees will be voted for their election. The Board of Directors knows of no reason why 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 Nucor’s Board of Directors may designate.

Nucor’s Board of Directors has adopted the following Corporate Governance Principle entitled “Effect of Withheld Votes in Uncontested Elections for Director.”

Any nominee for director in an uncontested election who receives a greater number of votes “withheld” from his or her election than votes “for” such election shall promptly tender his or her resignation for consideration by the Governance and Nominating Committee. The Committee shall evaluate the director’s tendered resignation taking into account the best interests of the Company and its stockholders and shall recommend to the Board whether to accept or reject such resignation. In making its recommendation, the Committee may consider, among other things, the effect of the exercise of cumulative voting in the election. The Board shall act within 120 days following certification of the stockholder vote and shall disclose its decision and the reasons therefore in an 8-K filing with the SEC. Any director who tenders his or her resignation pursuant to this principle shall not participate in any committee or board consideration of it.

Nucor’s Board of Directors recommends a vote FOR the election of the two nominees as directors.

CORPORATE GOVERNANCE AND BOARD OF DIRECTORS

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, the functioning of the Board and its Committees, the compensation of directors, and annual performance evaluations of the Board and our Chief Executive Officer. These Corporate Governance Principles are posted on our website at www.nucor.com. The information on our website is not a part of this proxy statement. You may also obtain a written copy of the Corporate Governance Principles by contacting Nucor’s Corporate Secretary at our executive offices.

Codes of Ethics.    Nucor’s Standards of Business Conduct and Ethics applies to all employees and directors of the Company. Nucor has also 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. Both of these documents are available on our website at www.nucor.com. You may also obtain a written copy of these codes of ethics by contacting Nucor’s Corporate Secretary at our executive offices.

Director Independence.    The Corporate Governance Principles provide that a majority of the members of Nucor’s Board of Directors must be “independent” under the listing standards of the NYSE. For a director to be considered independent, he or she cannot have any of the disqualifying relationships enumerated by the corporate governance rules of the NYSE. In addition, the Board of Directors must determine that the director does not otherwise have any direct or indirect material relationship with the Company. As permitted by the corporate governance rules of the NYSE, the Board of Directors has adopted categorical standards to assist its members in determining whether a particular relationship a director has with the Company is a material relationship that would impair the director’s independence. These categorical standards, which are set forth below, 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.”

• Relationships involving (1) the purchase or sale of products or services, (2) the purchase, sale or leasing of real property or (3) lending, deposit, banking or other financial service relationships, either by or to the Company or its subsidiaries and involving a director, his or her immediate family members, or an organization of which the director or an immediate family member is a partner, shareholder, officer, employee or director if the following conditions are satisfied:

• any payments made to, or payments received from, the Company or its subsidiaries in any single fiscal year within the last three years do not exceed the greater of (i) $1,000,000 or (ii) 2% of such other organization’s consolidated gross revenues;

• the products and services are provided in the ordinary course of business and on substantially the same terms and conditions, including price, as would be available to similarly situated customers;

• the relationship does not involve consulting, legal or accounting services provided to the Company or its subsidiaries; and

• any extension of credit was in the ordinary course of business and was made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other similarly situated borrowers.

• Any other relationship between the Company or one of its subsidiaries and a company (including a limited liability company) or partnership to which a director is connected solely as a shareholder, member or partner as long as the director is not a principal shareholder or partner of the organization. For purposes of this categorical standard, a person is a principal shareholder of a company if he or she directly or indirectly, or acting in concert with one or more persons, owns, controls or has the power to vote more than 10% of any class of voting securities of the company. A person is a principal partner of a partnership if he or she directly or indirectly, or acting in concert with one or more persons, owns, controls or has the power to vote a 25% or more general partnership interest, or more than a 10% overall partnership interest. Shares or partnership interests owned or controlled by a director’s immediate family member who shares the director’s home are considered to be held by the director.

• Contributions made or pledged by the Company, its subsidiaries or by any foundation sponsored by or associated with the Company or its subsidiaries to a charitable organization of which a director or an immediate family member is an executive officer, director or trustee if the following conditions are satisfied:

• within the preceding three years, the aggregate amount of such contributions during any single fiscal year of the charitable organization did not exceed the greater of (i) $1,000,000 or (ii) 2% of the charitable organization’s consolidated gross revenues for that fiscal year; and

8

• the charitable organization is not a family foundation created by the director or an immediate family member.

For purposes of this categorical standard, contributions made to any charitable organization pursuant to a matching gift program maintained by the Company or by its subsidiaries or by any foundation sponsored by or associated with the Company or its subsidiaries shall not be included in calculating the materiality threshold set forth above.

• If the director, or an immediate family member, is an executive officer of another organization in which the Company owns an equity interest and if the amount of the Company’s interest is less than 10% of the total voting interest in the other organization.

• A relationship involving a director’s relative who is not an immediate family member of the director.

• In the last five years, the director has not been an executive officer, founder or principal owner of a business organization acquired by the Company, or of a firm or entity that was part of a joint venture or partnership including the Company.

In February 2008, the Board of Directors reviewed the status of each director, applying the independence standards of the corporate governance rules of the NYSE and those set forth in Nucor’s Corporate Governance Principles. In their review, the Board considered all relationships and transactions between each director (and his or her immediate family and affiliates) and each of the Company and its management and the Company’s independent registered public accounting firm. The relationships that the Board of Directors reviewed and considered included the following. Peter C. Browning is a director of Wachovia Corporation, a bank holding company whose principal bank subsidiary, Wachovia Bank, N.A., is one of the participating banks in the Company’s unsecured revolving credit facility and provides other commercial banking services to the Company. The Board of Directors has determined that those relationships that do exist or did exist within the last three years (except for Mr. DiMicco’s) all fall below the thresholds in the categorical standards adopted by the Board of Directors to assist it in making determinations of independence.

Based on this review, the Board of Directors affirmatively determined that all of the nominees and directors continuing in office, with the exception of Daniel R. DiMicco, the Company’s Chairman, President and Chief Executive Officer, are independent as defined in Nucor’s Corporate Governance Principles and the corporate governance rules of the NYSE.

Attendance at the Board of Directors and Committee Meetings.    The Board of Directors of Nucor held ten meetings during 2007. Each of the directors attended 75% or more of the aggregate number of meetings of the Board and committees of the Board on which the director served.

Lead Director.    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 Board after the annual meeting of stockholders, and he or she serves at the pleasure of the Board. In May 2007, the Board reappointed Peter C. Browning to serve as Lead Director. The Lead Director’s responsibilities are set forth in the Company’s Corporate Governance Principles and include:

• Providing leadership to the Board of Directors;

• Chairing board meetings in the absence of the Chairman;

• Organizing, setting the agenda for and leading executive sessions of the independent directors without the attendance of management;

• Serving as a liaison between the Board and the Chairman;

• Consulting with the Chairman and the Secretary to set the agenda for board meetings;

• Meeting with the Chairman between board meetings as appropriate in order to facilitate board meetings and discussions.

Executive Sessions of the Non-Management Directors.    The non-management directors, all of whom are independent, meet in executive session prior to or after each quarterly board meeting at regularly scheduled executive sessions and as necessary prior to or after other board meetings. Mr. Browning, as Lead Director, presides over these executive sessions.

Attendance at Annual Meetings of Nucor’s Stockholders.    In accordance with Nucor’s policy requiring all directors to attend the annual meeting of stockholders, all of Nucor’s directors attended last year’s annual meeting.

Committees of the Board of Directors and their Charters.    The Board of Directors of Nucor has three standing committees: the Audit Committee, the Compensation and Executive Development Committee, and the Governance and

9

Nominating Committee. Each of these committees acts pursuant to a written charter adopted by the Board of Directors. A copy of each charter is available on our website at www.nucor.com. You may also obtain a written copy of these charters by contacting Nucor’s Corporate Secretary at our executive offices.

The Audit Committee.    The Audit Committee assists the Board in its oversight of the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, the qualifications and independence of the registered public accounting firm engaged to prepare an audit report with respect to the Company’s financial statements and the performance of the Company’s internal audit function. Pursuant to its written charter, the Audit Committee is directly responsible for, among other things, (1) the appointment, compensation and oversight of the independent auditors for the Company, (2) approving in advance all auditing services and permitted non-auditing services to be provided by the Company’s independent auditors, (3) reviewing with the auditors the plan and scope of the audit and audit fees, (4) monitoring the adequacy of the Company’s reporting and internal controls, and (5) meeting periodically with internal auditors, independent auditors and management.

The Audit Committee is composed entirely of independent directors: Mr. Daley (Chairman), Mr. Browning, Mr. Gantt, Dr. Haynes, Dr. Hlavacek and Mr. Walker. All of the members of the Audit Committee are independent as defined in the NYSE listing standards and the applicable SEC regulations for audit committee members. In the opinion of the Board, these directors are free of any relationship with the Company, its management or the independent registered public accounting firm appointed by the Audit Committee that would interfere with their exercise of independent judgment as members of the Audit Committee. All members of the Audit Committee are financially literate as the Board in its business judgment interprets such qualification. The Board has determined that Mr. Daley, the Chairman of the Audit Committee, is qualified as an audit committee financial expert within the meaning of SEC regulations and that he has accounting and related financial management expertise within the meaning of the NYSE listing standards. The Audit Committee held seven meetings during 2007.

The Compensation and Executive Development Committee.    The Compensation and Executive Development Committee is directly responsible to the Board of Directors, and through the Board to Nucor’s stockholders, for developing and administering the compensation program for Nucor’s executive officers.

In making its determinations with respect to executive compensation, the Committee is supported by James M. Coblin, Nucor’s Vice President of Human Resources, and A. Rae Eagle, Nucor’s General Manager and Corporate Secretary. In addition, the Company has historically engaged the services of a compensation consultant. In 2007, the Committee retained the services of Pearl Meyer & Partners to assist with its review of the compensation package of the Chief Executive Officer and other executive officers. In addition, Pearl Meyer & Partners was retained to assist the Committee with several special projects, including reviewing and developing the peer groups, monitoring trends in executive and non-employee director compensation, and assisting in the preparation of the executive compensation related disclosure in this proxy statement.

The Committee retains Pearl Meyer & Partners directly, although in carrying out assignments, Pearl Meyer & Partners also interacts with Company management when necessary and appropriate. Specifically, the Vice President of Human Resources and the Corporate Secretary interact with the consultants in order to provide compensation and performance data for the executive officers and the Company. In addition, Pearl Meyer & Partners may, in its discretion, seek input and feedback from the Chief Executive Officer and Chief Financial Officer regarding its consulting work product prior to presentation to the Committee in order to confirm its alignment with the Company’s business strategy, determine what additional data may need to be gathered, or identify other issues, if any, prior to presentation to the Committee.

The Committee frequently requests the Chairman and Chief Executive Officer to be present at Committee meetings where executive compensation and Company performance are discussed and evaluated. The Chairman and Chief Executive Officer is free to provide insight, suggestions or recommendations regarding executive compensation if present during these meetings or at other times. However, only independent Committee members are allowed to vote on decisions made regarding executive compensation.

The Committee meets with the Chairman and Chief Executive Officer to discuss his own compensation package, but ultimately, decisions regarding his compensation are made by the Committee, meeting in executive session, solely based upon the Committee’s deliberations. Decisions regarding other executive officers are made by the Committee after considering recommendations from the Chairman and Chief Executive Officer.

The Compensation and Executive Development Committee is composed entirely of independent directors: Dr. Haynes (Chairman), Mr. Browning, Mr. Daley, Mr. Gantt, Dr. Hlavacek, Mr. Kasriel and Mr. Walker. All of the members of the Committee meet the independence requirements of the NYSE listing standards for compensation committee members. In the

10

opinion of the Board, these directors are free of any relationship that would interfere with their exercise of independent judgment as members of the Committee. The Committee held five meetings during 2007.

The Governance and Nominating Committee.    The Governance and Nominating Committee is responsible for, among other things, (1) developing and recommending to the Board of Directors specific guidelines and criteria for selecting nominees for election to the Board of Directors, (2) reviewing the qualifications of and making recommendations to the Board regarding nominees for election as a director at each annual meeting of stockholders and the nominees for directors to be elected by the Board of Directors to fill any vacancies or newly created directorships, (3) making recommendations to the Board concerning the size and composition of the Board, the size and composition of each standing committee of the Board and the responsibilities of each standing committee of the Board of Directors, (4) overseeing and arranging the annual process of evaluating the performance of the Board of Directors and the Company’s management and (5) developing and recommending to the Board of Directors a set of corporate governance principles for the Company.

The Governance and Nominating Committee is composed entirely of independent directors: Mr. Browning (Chairman), Mr. Daley, Mr. Gantt, Dr. Haynes, Dr. Hlavacek, Mr. Kasriel and Mr. Walker. All of the members of the Committee meet the independence requirements of the NYSE listing standards for nominating committee members. In the opinion of the Board, these directors are free of any relationship that would interfere with their exercise of independent judgment as members of the Committee. The Committee held five meetings during 2007.

Annual Evaluation of Directors and Committee Members.    Our Board of Directors evaluates the performance of each director standing for reelection, each Committee of the Board 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 standing for reelection, each committee and the Board of Directors. 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 and committee.

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 SEC rules for disclosure of transactions with the Company’s directors, business and other organizations with which its directors are affiliated, executive officers, members of their immediate families and other related persons, which is administered by the Audit 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 Audit 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, the business reasons for entering into the transaction, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

How to Communicate with the Board of Directors and Non-management Directors.    Interested persons wishing to communicate with our Board of Directors, or any of our individual directors, may do so by sending a written communication to Peter C. Browning or any other individual director in care of Nucor Corporation, 1915 Rexford Road, Charlotte, North Carolina 28211. Interested persons wishing to communicate with Mr. Browning, as Lead Director, or with the non-management directors as a group may do so by sending a written communication addressed to Mr. Browning at our executive offices. Any communication addressed to Mr. Browning or any individual director that is received at the executive offices of Nucor will be delivered or forwarded to Mr. Browning or the individual director as soon as practicable. Nucor will forward all communications from its stockholders or other interested persons that are addressed simply to the Board of Directors to the chairman of the committee of the Board of Directors whose purpose and function is most closely related to the subject matter of the communication.

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 received by Nucor’s Corporate Secretary not less than sixty (60) and not more than ninety (90) days prior to the annual meeting. The notice must contain certain information about the nominee and the stockholder submitting the nomination including, (i) with respect to the nominee, the nominee’s name, age, business and residential address, principal occupation or employment, the number of shares beneficially owned by the nominee and any other information required to be disclosed in solicitations for proxies to elect

11

directors pursuant to the SEC’s rules and regulations and (ii) with respect to the stockholder submitting the nomination, the stockholder’s name and address, as they appear on our books and records and the number of shares beneficially owned by that stockholder. A stockholder who is interested in recommending a director candidate should request a copy of Nucor’s bylaw provisions by writing to Nucor’s Corporate Secretary at Nucor’s executive offices, 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 Committee has a policy that potential nominees shall be evaluated no differently regardless of whether the nominee is recommended by a stockholder, a board member or Nucor’s management. The Committee considers potential nominees from all these sources, develops information from many sources concerning the potential nominee, evaluates the potential nominee 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 nominees for director. Nucor may do so again in the future.

In evaluating potential nominees for election as members of the Board, the Committee considers the following to be minimum qualifications that any nominee must possess. 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 them 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 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.

DIRECTOR COMPENSATION

In 2007, the Compensation and Executive Development Committee benchmarked director compensation comparing Nucor’s director compensation to 45 materials and industrial companies of similar size. Based on this data, the Board approved changes to the equity retainer described below. The Board does not plan on making any further changes to director compensation until 2009 or later.

In 2007, non-employee directors were paid standard directors’ fees of $60,000 annually, in $15,000 quarterly payments, including meeting fees. The Lead Director of Nucor was paid an additional $30,000, for a total of $90,000, in $22,500 quarterly payments, including meeting fees. The chairmen of the Governance and Nominating Committee and the Compensation and Executive Development Committee received an additional $6,000 each, in $1,500 quarterly payments. The chairman of the Audit Committee received an additional $12,000, in $3,000 quarterly payments.

Directors who are not senior officers of Nucor are granted each June 1 restricted stock units under the Company’s 2005 Stock Option and Award Plan. In 2007, the number of restricted stock units awarded was equal to $100,000 ($140,000 in the case of the Lead Director) divided by the fair market value of a share of Nucor common stock on the last trading day

12

immediately preceding the grant date (rounded down to the next whole unit). The restricted stock units granted to each non-employee director are fully vested on the grant date, but are payable in the form of shares of Nucor common stock only after the termination of the director’s service on the Board of Directors.

The following table summarizes the compensation paid to each non-employee director for his or her Board and committee services during 2007. Mr. Raymond J. Milchovich resigned from the Nucor Board of Directors on September 6, 2007 to have more time available to fulfill other commitments. Mr. John H. Walker joined the Nucor Board of Directors on January 1, 2008 and is therefore not included in the table.

Fees Paid to Independent Registered Public Accounting Firm

For the fiscal years ended December 31, 2006 and 2007 fees billed for services provided by PricewaterhouseCoopers LLP (“PwC”) were as follows:

	2006		2007
Audit Fees (1)	$	1,715,500	$	2,384,994
Audit-Related Fees (2)		—		14,190
Tax Fees (3)		353,288		126,414
All Other Fees		—		—

(1) Audit fees consist of fees for professional services rendered in connection with the audit of Nucor’s consolidated annual financial statements, for the review of interim consolidated financial statements in Forms 10-Q and for services normally provided in connection with statutory and regulatory filings or engagements. Audit fees also include fees for professional services rendered for the audit of the effectiveness of internal control over financial reporting.

(2) Audit-related fees consist of fees billed for the audits of certain employee benefit plans.

(3) Tax fees consist of fees billed for professional services rendered for tax compliance, tax advice and tax planning.

In 2006 and 2007, all audit-related services, tax services and other services were pre-approved by the Audit Committee, which concluded that the provision of such services by PwC was compatible with the maintenance of that firm’s independence in the conduct of its auditing functions. The Audit Committee is responsible for the pre-approval of all auditing services and permitted non-audit services performed for Nucor by PwC. The Audit Committee has delegated its authority to approve in advance all permitted non-audit services to be provided by PwC to the Chairman of the Audit Committee; provided, however, any such services approved by its Chairman shall be presented to the full Audit Committee at its next regularly scheduled meeting.

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion & Analysis (“CD&A”) outlines Nucor’s executive compensation philosophy, objectives and processes. It explains how the Compensation and Executive Development Committee (the “Committee”) makes executive compensation decisions, the data used and the reasoning behind the decisions that are made.

Following this CD&A are tables detailing the compensation of our Named Executive Officers (“NEOs” or “Executive Officers”) along with descriptions and other narrative explaining the information in the tables. Also included is a section presenting the potential compensation Executive Officers would receive if they had been terminated on December 31, 2007.

Compensation Philosophy

Nucor’s executive compensation philosophy is based on and supports the Company’s overall management philosophy. Our philosophy is to:

1. Hire and retain highly talented and productive people.

2. Put them in a simple, streamlined organizational structure that allows them to innovate and make quick decisions that affect results.

3. Pay them not just for showing up, but for producing results.

Nucor takes an egalitarian approach to providing benefits to its employees. That is, the upper levels of management do not enjoy better benefits such as insurance programs, vacation schedules or holidays. 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 NEOs. In addition, Executive Officers do not receive traditional executive perquisites such as company cars, executive dining rooms or personal use of corporate aircraft.

The Company believes that the compensation provided to its Executive Officers should be commensurate and aligned with the performance of the Company and creation of long-term stockholder value. The key principles guiding Executive Officer compensation are to 1) reward Executive Officers for superior performance, 2) provide incentives that are based on overall Company performance, and 3) pay guaranteed compensation (meaning those elements of pay, such as base salary and benefits, that are not dependent on performance) that is below the median for similar size industrial and materials companies.

The objectives of our Executive Officer compensation plans are to:

• Retain the services of our Executive Officers.

• Motivate our Executive Officers to advance the interests of the Company and build stockholder value.

• Reward our Executive Officers for their contributions to the success of the Company and to the stockholder value that they help create.

• Measure the success of the Company through Return on Equity (“ROE”), Return on Average Invested Capital (“ROAIC”) and sales growth.

• Reward Executive Officers as a team based on overall Company performance.

Executive Officer compensation at Nucor is highly leveraged, meaning that a significant portion of an executive’s potential compensation is variable, because the compensation is earned under incentive plans that are based on the performance of the Company and the value delivered to Nucor’s stockholders. The incentive plans are designed to function in a cyclical environment by measuring performance relative to two performance comparator groups: a group of steel industry competitors and a group of capital intensive companies that were chosen at the time they were added to the peer group for their superior financial performance. The incentive plans are also designed to pay well when performance is high and not pay any incentive if performance is poor. The Company believes that variable compensation plays an important role in Nucor’s financial performance. The Company has earned a profit every year since 1966, through business cycles where peer companies showed losses.

The performance comparator groups are used to benchmark financial performance for incentive plan purposes. They are not used to benchmark compensation.

Base salaries are set below the median of survey data for similar size industrial and materials companies. Therefore, the Company recognizes the risk that Executive Officers may earn below median levels of compensation when Company

16

performance is poor, even if an Executive Officer’s individual performance may be superior. This practice has in the past and may in the future result in Executive Officers earning less than their counterparts in other similar size industrial and materials companies.

A portion of the compensation Executive Officers may earn under the incentive plans is stock-based awards that must be held until retirement. The Committee believes the requirement to hold stock-based awards until retirement has been successful in meeting the Company’s objectives of retention and succession planning. All Executive Officers have been with the Company for more than 15 years.

Incentive Opportunity Levels and Mix of Components of Compensation.    When the current annual and long-term incentive plans were developed in 2003 and approved by stockholders, the Committee established the incentive opportunity levels and mix of compensation components based on a sensitivity analysis which assumed some years of lower performance where no payouts would be earned and some years where maximum payouts would be achieved. This variability was intended to reflect fluctuations in economic activity. The Committee intended that through a multi-year business cycle and assuming target levels of performance, total compensation for executive officers would be near the median of similar size industrial and materials companies. The Committee periodically reviews actual performance and compares such performance to the parameters identified when the plans were originally established to ensure actual results over time are appropriate.

The annual and long-term incentive plans are designed to work without significant changes over a long time period. For example, minimum, target and maximum incentive plan payouts as a percentage of salary, including mix of cash or stock, were established and approved by stockholders in 2003. Therefore, the Committee makes few changes from year to year. The Committee annually reviews the performance comparator peer groups on which incentive payouts are based to ensure that the comparator peers meet the plans’ requirements and the criteria the Committee has established for inclusion in the comparator group. In addition, the Committee annually adjusts base salaries (which impact incentive plan opportunities) and sets the threshold level of performance under the annual incentive plan. The maximum incentive plan payout was approved by stockholders in 2003.

Pursuant to these stockholder-approved plans, 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. The Committee reviewed the payouts and determined that the incentive plan payouts produced the desired result and therefore it did not exercise any discretion in 2007.

At the time the stockholders approved the plans in 2003, the Committee determined that the mix of base salary and annual and long-term incentives and the incentive opportunities at target and maximum were appropriate to accomplish the goal of paying near the median total compensation of survey data for industrial and materials companies of similar size. The Committee annually asks the compensation consultant to compare Nucor’s actual total compensation over a ten year period to this benchmark using nationally recognized compensation survey data in order to ensure that total compensation remains reasonable. The Committee has reviewed the comparisons and believes total compensation, the mix of compensation components, and the target and maximum incentive opportunities are reasonable and consistent with the Committee’s philosophy.

Nucor has submitted for stockholder approval new annual and long-term officer incentive compensation plans. These plans are similar to those approved by stockholders in 2003. However, the new annual and long-term officer incentive compensation plans provide the Committee flexibility in adjusting the incentive opportunities and the performance measures. For 2008, the mix of components of compensation, performance targets and levels of incentive opportunity are the same as how the plans have been administered in the past.

Stock Ownership Guidelines.    Executives have an opportunity to earn a significant number of shares. The Committee believes that requiring executive officers to hold a significant number of shares aligns their interests with stockholders and has therefore adopted stock ownership guidelines for Nucor’s Executive Officers. The guideline number of shares ranges from 180,000 shares for the Chief Executive Officer to 90,000 shares for Nucor’s executive vice presidents. The Committee has compared these guidelines to those of other industrial and materials companies of similar size and published surveys and found that the Company’s guidelines are much higher than other companies. Under the guidelines, Executive Officers have five years to achieve ownership of the guideline number of shares. 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 within five years of being elected an officer. All Nucor Executive Officers were in compliance with the stock ownership guidelines as of December 31, 2007.

Internal Revenue Code Section 162(m).    Internal Revenue Code Section 162(m) limits the amount of compensation paid to the NEOs that may be deducted by Nucor for federal income tax purposes in any fiscal year to $1,000,000. “Performance-based” compensation that has been approved by Nucor’s stockholders is not subject to the $1,000,000

17

deduction limit. Nucor’s incentive plans have all been approved by Nucor’s stockholders, and awards under those plans, other than certain time vesting restricted stock units, constitute “performance-based” compensation that is not subject to the Code Section 162(m) deduction limit. The Committee has not adopted a formal policy that all compensation paid to the named executive officers must be deductible.

Components of Compensation

The Company provides four compensation components:

• Base salary

• Annual incentives

• Long-term incentives

• Benefits

As described above, these components provide a balanced mix of guaranteed compensation and variable, at-risk compensation with an emphasis on annual and long-term incentives. By providing this balanced compensation portfolio, we provide Executive Officers 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 high level of performance for the Company.

Decisions with regard to the actual amount or value of compensation granted to each executive are based on actual Company performance. Individual performance is not taken into account. Individuals who do not perform are not employed by Nucor.

Base Salary

The Committee’s goal is to set the base salaries of Nucor’s Executive Officers at approximately 90% of the median base salary level for comparable positions at similar industrial and material companies. The Committee sets base salaries below the median because of the Committee’s desire to orient the Executive Officers’ total pay significantly towards at-risk incentive compensation.

With the assistance of the Vice President of Human Resources and the Committee’s independent compensation consultant, the Committee usually reviews national compensation surveys of executives of similar size manufacturing companies. When setting base salaries for 2007, the Committee did not review current salary comparability data, but rather updated prior year information by 2.5% based on surveys of budgeted executive compensation salary.

The CEO recommended that executive officer salary increases be 2.5%, consistent with the budgeted salary increases for other Nucor employees. Over time, the Executive Officers’ base salaries have slipped below the 90% of median target level. While the Committee considers market data important in its decision to adjust base salaries, the Committee also considers the relationship between each senior officer’s compensation. The Committee considered the CEO’s suggestions and approved them as proposed. In doing so, the Committee considered the relationship between each Executive Officer’s salary, the increases for other Nucor employees, recent payouts from incentive plans and the benchmarking of total compensation discussed above. In addition, the Committee increased the CEO’s compensation by 4.1%. In making the decision to increase the CEO’s salary by more than other Executive Officers, the Committee’s recognized that the CEO’s total compensation is significantly below 90% of the median and significantly below the benchmark of total compensation discussed above.

Name	Position	2006 Salary		Salary Adjustment		2007 Salary
Daniel R. DiMicco	Chairman, President and Chief Executive Officer	$	725,000	4.1	%	$	755,000
Terry S. Lisenby	Chief Financial Officer, Treasurer and Executive Vice President	$	413,900	2.5	%	$	424,200
John J. Ferriola (1)	Chief Operating Officer of Steelmaking Operations	$	376,300	2.5	%	$	385,700

D. Michael Parrish	Executive Vice President	$	376,300	2.5	%	$	385,700
Joseph A. Rutkowski	Executive Vice President	$	376,300	2.5	%	$	385,700

18

(1) Nucor promoted Mr. Ferriola from Executive Vice President to Chief Operating Officer of Steelmaking Operations effective September 30, 2007. His annual salary rate was increased from $385,700 to $424,200 effective as of that date.

Annual Incentives

The Annual Incentive Plan (“AIP”) provides Executive Officers an opportunity to receive annual cash incentive awards based on the Company’s 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 fiscal year of up to a maximum of 300% of the Executive Officer’s base salary:

• Seventy-five percent of the maximum incentive award or 225% of base salary (75% of 300% = 225%) is earned based on Nucor’s ROE. For fiscal 2007, the Committee set the threshold at 7% ROE and the maximum at 20% ROE. If Nucor achieves the threshold ROE, Executive Officers will earn an incentive award equal to 20% of their base salary. If Nucor’s ROE for the fiscal year exceeds 20%, Executive Officers will earn an incentive award equal to the maximum 225% of their base salary. A prorated incentive award is earned for ROE between 7% and 20%.

The current stockholder-approved plan provides that the threshold ROE performance measure shall not be less than 3% or greater than 7%. The plan also provides that the maximum incentive is earned if ROE exceeds 20%. The Committee has submitted for stockholder approval changes to the plan that allows the Committee to eliminate the restrictions on setting performance thresholds and maximums.

• 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 a comparison of Nucor’s net sales growth with the net sales growth of members of a steel industry peer group (discussed below) as follows:

Steel Peer Group Rank (1)	Percentage of Performance Award Opportunity	Performance Award Payment (% of Base Salary)
1	100%	75.00%
2	90%	67.50%
3	80%	60.00%
4	70%	52.50%
5	55%	41.25%
6	40%	30.00%
7	30%	22.50%
8	20%	15.00%
9	10%	7.50%
10	0%	0.00%

(1) The table represents potential AIP awards for 2007 net sales growth. The peer group for future years may include more or less peer companies. The potential awards are adjusted to reflect the number of peer companies in the group.

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 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.

2007 Performance

Based on Nucor’s ROE of 28.97% and net sales growth of 12.49% for 2007, Executive Officers earned the maximum award of 225% of base salary for the ROE performance measure and an award of 41.25% of base salary for the net sales growth performance measure, receiving total incentive compensation under the AIP equal to 266.25% of base salary.

None of the NEOs elected to defer their 2007 AIP awards.

19

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. The Committee believes that half of the long-term awards should be earned relative to superior performance as compared to other steel companies and half earned relative to high performing companies. The Committee believes that this plan design provides an incentive to not just perform better than industry competitors, but also other capital intensive companies. The Committee also believes it is appropriate to provide a level of retention through time vesting restrictive stock.

As discussed above, the level of long-term incentive grants were established in 2003 when the plans were approved by stockholders. The Committee annually benchmarks total compensation to ensure the grant sizes are still competitive and reasonable as compared to the median of other similar size industrial and materials companies based on nationally recognized surveys.

The Long-Term Incentive Plan

Executive Officers earn incentive compensation under the Long-Term Incentive Plan (“LTIP”) based on Nucor’s performance during the LTIP’s performance periods. The performance periods commence every January 1 and last for three years.

The target award under the LTIP for each performance period is a number of shares of Nucor common stock. The 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 day immediately preceding the first day of the performance period. The maximum award that an Executive Officer may earn under the LTIP is equal to 200% of the number of shares in the target award. Fifty percent (50%) of the LTIP award is based on Nucor’s ROAIC for the performance period relative to its principal competitors in the steel industry based on the table below. The remaining 50% of the award is based on Nucor’s ROAIC for the performance period relative to a peer group of high-performing companies in capital-intensive industries based on the tables below.

Steel Peer Group (1)		High-Performing Peer Group (1)
Rank	Award as a % of Target	Rank	Award as a % of Target
1 or 2	100%	1 or 2	100%
3 or 4	75%	3 or 4	75%
5	60%	5 or 6	60%
6	50%	7 or 8	50%
7	40%	9 or 10	40%
8	25%	11	25%
9 or 10	0%	12 or 13	0%

(1) These tables represent the potential awards based on the LTIP performance period that began January 1, 2007. The peer group for other performance periods may include more or less peer companies. The potential awards are adjusted to reflect the number of peer companies in the group.

One-half of the LTIP is paid in cash; one-half of the LTIP is paid in restricted stock. One-third of the restricted stock vests upon 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 the 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 on deferred restricted stock awards in cash within 30 days of when stockholders are paid.

2007 Performance

Based on Nucor’s ROAIC of 81.80% for the LTIP performance period that began January 1, 2005 and ended December 31, 2007, Executive Officers earned the maximum award of 200% of the number of shares in each Executive Officer’s target LTIP award. The Company 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 2008.

Restricted Stock Units

Nucor has not granted stock options since 2005, when all of Nucor’s key employees, including its Executive Officers, received stock option awards. All outstanding stock options are vested and currently exercisable. Beginning in 2006, the Company was required to account for stock options as an expense in the financial statements. The Company considered the financial statement impact of future option grants and decided restricted stock units (“RSUs”) provide a better long-term incentive instrument for key employees; therefore, the Company stopped making option grants and began granting RSUs.

The Committee believes that RSUs align Executive Officers with stockholders and provide significant retentive characteristics. Grant levels are based on the historical value of options granted prior to 2006 and the annual total compensation review.

Each June 1, a base amount of RSUs is granted to each Executive Officer. One-third of the base amount of RSUs become vested on each of the first three anniversaries of the June 1 award date, or upon the Executive Officer’s retirement (defined below), death or disability while employed by Nucor.

Additional RSUs (“Performance RSUs”) are granted contingent on the Company’s ROE for the prior fiscal year. Performance RSUs vest upon the Executive Officer’s retirement, death or disability while employed by Nucor. The threshold ROE required for a grant of Performance RSUs is 5%. The maximum number of Performance RSUs is granted for ROE of 20% or more.

RSUs are granted each June 1. The total number of RSUs 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 the Company’s common stock on the last trading day immediately preceding the annual June 1 grant date.

Position	Base Amount of Restricted Stock Units Granted Market Value		Performance Restricted Stock Units Market Value (Based on Prior Fiscal Year ROE)
			5%		10%		15%		20%
			ROE		ROE		ROE		ROE
Chief Executive Officer	$	400,000	$	300,000	$	600,000	$	800,000	$	1,000,000
Chief Financial Officer		100,000		150,000		200,000		300,000		400,000
Executive Vice President		83,333		125,000		166,667		250,000		333,333

Retirement for purposes of the RSUs is defined as Committee-approved retirement upon termination of employment and completion of the following age and service requirements:

Age	65	64	63	62	61	60	59	58	57	56	55
Years of Service	-0-	2	4	6	8	10	12	14	16	18	20

2007 Performance

On June 1, 2007, Executive Officers received the base amount of RSUs and earned the maximum performance RSUs based on Nucor’s ROE of 38.6% in 2006.

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.

Post Termination Compensation

The Committee believes that Executive Officers should be provided a reasonable severance benefit in the event an executive’s position is eliminated. Severance benefits for Executive Officers reflect the fact that it may be difficult to find comparable employment within a short period of time. We believe relative to the overall value of any potential transaction, these potential post-termination change in control benefits are reasonable.

21

Non-Compete and Non-Solicitation Agreements

Executive Officers have agreed not to compete with Nucor during the 24-month period following their termination of employment with Nucor for any reason other than death in exchange for monthly cash payments from the Company 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 one of Nucor’s competitors or encouraging any of Nucor’s employees to terminate their 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.

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 twelve months immediately preceding the termination of his employment, divided by twelve. If an Executive Officer who is receiving monthly installment payments dies within twelve 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 twelve 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 twelve or more months following termination of his employment.

The non-compete and non-solicitation agreements were first implemented in 1999 to protect Nucor from Executive Officers who left our employment to compete with us and/or recruit our employees. A number of senior employees had left to compete with Nucor. Since these agreements have been implemented, no Executive Officer has left Nucor. The amount of the non-competition benefit was increased when revised agreements were implemented in 2001 to an amount deemed by the Committee to discourage employees from leaving. Each year, the Committee reviews total compensation, including these non-compete and non-solicitation benefits, to ensure that such amounts remain reasonable.

Severance Benefits

The Executive Officers are entitled to receive severance payments following termination of employment or their resignation, death or retirement under a general severance policy adopted by the Board of Directors that applies to all Nucor officers. 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, the Executive Officer, or his estate, will be entitled to receive a severance payment equal to the greater of (A) one month of his base salary for each year of service to Nucor with a minimum severance payment of six months’ base salary or (B) the value of the total number of his deferral incentive common stock units under the AIP and his unvested shares of Nucor common stock granted under the LTIP. If the Executive Officer is age 55 or older, the Executive Officer, or his estate, will be entitled to receive a severance payment equal to one month of base salary for each year of service to Nucor with a minimum severance payment of six months’ base salary.

Each year, the Committee reviews total compensation, including these severance benefits, to ensure that such amounts remain reasonable.

Change in Control Benefits

Nucor does not provide any Executive Officer with change in control benefits other than accelerated vesting of previously granted RSUs. If an Executive Officer is terminated following a change in control, the Executive Officer would receive severance and non-compete payments pursuant to the agreements described above. Executive officers are responsible for taxes on all payments; no gross ups are provided.

Use of Performance Comparator Peer Groups

The Company 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 peers. Two performance comparator peer groups are used, the Steel Peer Group and the High Performing Peer Group. The Committee sets the performance comparator peer group members 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 peer group used for one performance period may differ from the group used in a different performance period.

23

The performance comparator peer groups for performance periods that began in 2007 are comprised of the following companies:

Steel Peer Group	High-Performing Peer Group
AK Steel Holdings Corporation	Alcoa, Inc.
Commercial Metals Co.	Carlisle Companies Inc.
Dofasco, Inc.	Caterpillar Inc.
Gerdau Ameristeel Corporation	CSX Corp.
IPSCO Inc.	General Dynamics Corporation
Quanex Corporation	Ingersoll-Rand Co. Ltd.
Steel Dynamics, Inc.	Johnson Controls Inc.
United States Steel Corporation	Norfolk Southern Corporation
Worthington Industries, Inc.	Southwest Airlines Co.
	Textron Inc
	United Technologies Corporation
	Vulcan Materials Co.

The Committee has used the following criteria for establishing performance comparator peer groups:

1. The steel peer group must be a group of not less than five (5) steel industry competitors.

2. The high performing peer group must be a group of not less than ten (10) high performing companies in capital intensive industries.

3. Steel competitors are defined as steel companies with product offerings similar to Nucor’s.

4. Companies included in the high performance peer group are respected capital intensive companies that have performed well over a long time period.

The Committee reviews the performance comparator peer groups annually. Companies may be added or dropped from the performance comparator peer groups based on performance or product mix (in the case of the steel peer group). The Committee maintains a list of potential peer group companies and reviews the Company’s performance relative to these potential peer group companies, industry benchmarks and market indexes.

The Committee does not use the performance comparator peer groups for purposes of benchmarking compensation.

(1) Represents restricted stock units awarded June 1, 2007 under the Restricted Stock Unit Plan (“RSP”).

(2) The Executive Officers were eligible to earn a range of performance-based payments under the AIP for the Company’s performance during 2007. The threshold and maximum amounts shown are equal to 7.5% and 300%, respectively, of each Executive Officer’s base salary. The AIP does not have a target award. The target amounts shown are equal to the AIP award for 2006 performance of 277.5% of base salary. For the 2007 performance period, the Executive Officers earned awards of 266.25% of base salary under the AIP. The dollar amounts of those awards are presented in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table.

(3) Represents the range of performance-based awards that may be earned under the LTIP for the 2007-2009 performance period. The awards, if any, will be made in March 2010. The grant date fair value is calculated by multiplying the fair market value of Nucor stock on the grant date by the target number of shares.

(4) Represents the award earned under the LTIP for the 2005-2007 performance period. The awards were made in March 2008.

(5) The Awards have been valued using the May 31, 2007 closing stock price of $67.54.

(6) The Awards have been valued using the December 31, 2006 closing stock price of $54.66.

(7) The Awards have been valued using the December 31, 2007 closing stock price of $59.22.

Non-Equity Incentive Plan Awards

Under the Annual Incentive Plan (“AIP”), a senior officer, including all NEOs, may earn a non-equity incentive award for each fiscal year of up to a total of 300% of the senior officer’s base salary. For a description of the AIP, please refer to “Annual Incentives” section of the CD&A. The AIP has no stated target. If Nucor’s performance had been the same as the prior year (2006), a senior executive would have earned a bonus of 277.5%. When an incentive plan has no stated target performance level, we are required to report as “Target” in column (d) of the table an amount based on the prior year’s performance. Therefore, the amounts listed in column (d) of the table under “Target” reflect an AIP award of 277.5%. Actual performance for the period ended December 31, 2007 resulted in an AIP award of 266.25%.

Equity Incentive Plan Awards

Restricted Stock Unit Plan (“RSP”)

Each year, on or about June 1, participants are granted a threshold or base amount of restricted stock units as long as Nucor’s earnings for the prior fiscal year are positive. An additional amount of restricted stock units may be granted based on Nucor’s ROE for the prior year. This award vests annually over the three-year period following the date of grant. In 2006, Nucor’s ROE exceeded the maximum performance goal and the executive officers received awards for both earnings and ROE performance. The restricted stock unit awards were granted on June 1, 2007 and are reported in column (i).

Long Term Incentive Plan (“LTIP”)

The range of potential grants for the performance period January 1, 2007 through December 31, 2009 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 “Long-term Incentives” section of the CD&A.

The LTIP payout for the 2005-2007 performance period are reported in columns (i) and (j). Actual performance for the LTIP performance period ending December 31, 2006 resulted in restricted shares issued on March 10, 2007 as follows:

	Shares Issued March 10, 2007
Daniel R. DiMicco	41,892
Terry S. Lisenby	23,921
John J. Ferriola	21,747
Hamilton Lott, Jr.	21,747
D. Michael Parrish	21,747
Joseph A. Rutkowski	21,747

One-third of the restricted shares issued on March 10, 2007 will become vested upon each of the first three anniversaries of the issuance date, or upon the senior officer’s attainment of age 55, death or disability while employed by Nucor. Pursuant to SFAS No. 123(R), these shares were granted at the beginning of the performance period, January 1, 2004, and are therefore not reported in the Grants of Plan Based Awards Table.

Outstanding Equity Awards at Fiscal Year-End Table

The table below shows the equity holdings for each Executive Officer on December 31, 2007.

Prior to 2006, stock option awards were granted to all key employees, including its Executive Officers under Nucor’s Incentive Stock Option Plans. All outstanding options under the Incentive Stock Option Plans are currently exercisable and expire seven years after the grant date.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities and Exchange Act of 1934 requires that our executive officers and directors file reports of their ownership and changes in ownership of Nucor common stock on Forms 3, 4 and 5 with the SEC and NYSE. The Company has reviewed all reports filed by its executive officers and directors and written representations made by its executive officers and directors with respect to the completeness and timeliness of their filings. Based solely on such review, all filings were timely made in 2007.

PROPOSAL 2

RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors recommends a vote FOR the proposal.

The Audit Committee of the Board of Directors has selected the firm of PricewaterhouseCoopers LLP to serve as the independent registered public accounting firm of Nucor for the fiscal year ending December 31, 2008. PricewaterhouseCoopers LLP has acted in such capacity for Nucor since 1989. Representatives of PricewaterhouseCoopers LLP are expected to be present at the annual meeting, will have the opportunity to make a statement if they so desire and are expected to be available to respond to appropriate questions.

Stockholder ratification of the Audit Committee’s selection of PricewaterhouseCoopers LLP as our independent registered public accounting firm is not required by our bylaws or otherwise. The Board is submitting the selection of PricewaterhouseCoopers LLP to the stockholders for ratification and will reconsider whether to retain PricewaterhouseCoopers LLP if the stockholders fail to ratify the Audit Committee’s selection. In addition, even if the stockholders ratify the selection of PricewaterhouseCoopers LLP, the Audit Committee may in its discretion appoint a different independent registered public accounting firm at any time during the year if the Audit Committee determines that a change is in the best interests of Nucor.

Nucor’s 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 fiscal year ending December 31, 2008. Unless otherwise specified, proxies will be voted FOR the proposal.

PROPOSAL 3

APPROVE THE ANNUAL AND LONG-TERM SENIOR OFFICERS INCENTIVE COMPENSATION PLANS

The Board of Directors proposes that stockholders approve the amended and restated Nucor Corporation Senior Officers Long-Term Incentive Plan and the amended and restated Nucor Corporation Senior Officers Annual Incentive Plan. Nucor’s Board of Directors has approved the amendment and restatement of both plans, subject to stockholder approval.

The plans are intended to comply with the “performance-based compensation” requirements of Section 162(m) of the Internal Revenue Code. In accordance with the requirements of Section 162(m), the stockholders initially approved the plans in 2003. To continue to comply with the requirements of Section 162(m), the stockholders must re-approve the material terms of the plans every five years. You are being asked to approve the amendment and restatement of the plans to preserve the Company’s federal income tax deduction for payments made to certain senior officers participating in the plans.

The plans have been amended to provide the Company more flexibility in determining the performance criteria and selecting the peer group companies under the plans. Other than in those two areas, the principal features of the plans are unchanged from the terms of the plans approved by the stockholders in 2003. The plans are summarized below. This summary is subject to the full terms and provisions of the plans, which are included at the end of this proxy statement.

Eligibility

Any regular, full-time employee of the Company or a subsidiary of the Company who (a) is designated as the Chairman or a Vice Chairman of the Board of Directors or (b) is serving as the Chief Executive Officer, the Chief Operating Officer, the Chief Financial Officer, the President, an Executive Vice President or a Vice President of the Company is eligible to participate in the plans. The Compensation and Executive Development Committee of the Board of Directors (the “Committee”) may also designate any other senior officer of the Company or a subsidiary as a participant in the plans. In 2007, 34 senior officers of the Company participated in the plans.

Annual Incentive Plan

The Nucor Corporation Senior Officers Annual Incentive Plan (the “AIP”) is intended to provide competitive annual incentive compensation to senior officers based on two performance measures:

• Nucor’s return on average stockholders’ equity or achievement or other performance criteria selected by the Committee during the AIP’s one year performance periods beginning each January 1; and

• growth in Nucor’s net sales during a performance period.

The other performance criteria that may be selected by the Committee include relative or comparative achievement by the Company or one or more subsidiaries or business units of: (a) return on equity; (b) revenue growth; (c) earnings before interest, taxes, depreciation and amortization; (d) earnings before interest, taxes and amortization; (e) operating income; (f) pre- or after-tax income; (g) cash flow; (h) cash flow per share; (i) net earnings; (j) earnings per share; (k) return on invested capital; (l) return on assets; (m) economic value added (or an equivalent metric); (n) stock price performance; (o) total stockholder return; (p) improvement in or attainment of expense levels; (q) improvement in or attainment of working capital levels; or (r) debt reduction.

A senior officer can earn an incentive award of up to 300% of the senior officer’s base salary as of the beginning of a performance period for significant achievement during the performance period under both measures. Seventy-five percent (75%) of the maximum incentive award (i.e., up to 225% of base salary) is available for award based on Nucor’s return on average stockholders’ equity or other performance criteria. The remaining 25% of the maximum award (i.e., up to 75% of the senior officer’s base salary) is available for award based on a comparison of Nucor’s net sales growth with the net sales growth of the members of a steel industry peer group.

At the beginning of each performance period, the Committee will designate a threshold return on average stockholders’ equity (or threshold achievement of other performance criteria) that must be achieved before any performance awards may be paid under the AIP for achievement of that performance criteria. The Committee will also designate at the beginning of each performance period a maximum return on average stockholders’ equity (or other performance criteria) which, if achieved, will result in the award of the maximum of 225% of each eligible employee’s base salary that may be paid under the AIP for achievement of that performance criteria. If the threshold performance is achieved, a performance award of 20% (or other

33

percentage set by the Committee at the beginning of the performance period) of each senior officer’s base salary compensation for the performance period will be awarded. If the performance achieved is higher than the threshold level but below the maximum level, the amount of the performance award, expressed as a percentage of each senior officer’s base salary will be determined by linear interpolation.

Each year, the Committee will also designate not less than five steel industry competitors as the members of the peer group for the net sales growth comparison and the amount of incentive compensation that will be awarded for levels of Nucor’s net sales growth when ranked against the peer group members.

If Nucor has no reported net earnings for a fiscal year, no incentive compensation will be awarded under the AIP. In addition, the Committee may reduce incentive compensation awards in its discretion so long as the same percentage reduction is made to each senior officer’s incentive compensation award.

To encourage greater Nucor stock ownership, senior officers have the opportunity to defer payment of up to one-half of any incentive award under the AIP. The amount of the deferred award will be converted into Nucor common stock units and credited to a deferral account. The AIP provides a deferral incentive to the senior officers by providing for the crediting of additional common stock units to the deferral account equal to 25% of the number of common stock units attributable to the amount of any incentive award the senior officer deferred. The senior officer will receive dividend equivalent payments based on the total number of common stock units credited to the deferral account. The senior officer will be fully vested in the common stock units attributable to the deferred incentive award. The additional common stock units attributable to the deferral incentive provided by the AIP will become vested upon the senior officer’s attainment of age 55 while employed or in the event the senior officer dies or becomes disabled before age 55 while employed. The vested common stock units will be distributed to the senior officer in the form of Nucor common stock following the senior officer’s retirement or other termination of employment.

Long-Term Incentive Plan

Long-term incentive compensation under the Nucor Corporation Senior Officers Long-Term Incentive Plan (the “LTIP”) is intended to increase senior management’s focus on Nucor’s long-term performance relative to that of its principal competitors in the steel industry and of certain other companies in capital intensive industries in the same general industry group as the steel industry. In general, performance periods under the LTIP commence every January 1 and last for three years.

The target award under the LTIP for each performance period is a number of shares of Nucor common stock. The number of shares is determined by dividing 85% of each senior officer’s annual base salary by the closing price of Nucor common stock on the day immediately preceding the first day of the performance period. For example, the number of shares comprising the target award for a senior officer with a base salary of $200,000 would be computed as follows – assuming the market price of Nucor stock was $65 on the day immediately preceding the first day of the performance period: $200,000 x 85% = $170,000/$65 = 2,615 shares. The maximum award that a senior officer may earn under the LTIP is equal to 200% of the number of shares in the target award.

Fifty percent of the LTIP award for a performance period will be based on Nucor’s return on average invested capital for the performance period relative to the return on average invested capital of its principal competitors in the steel industry. The remaining 50% of the award will be based on Nucor’s return on average invested capital for the performance period relative to the return on average invested capital of companies in capital intensive industries and classified in either the Materials Sector or the Industrial Sector of the Global Industry Classification Standard. Each year, the Committee will designate not less than 5 steel industry competitors as the members of the steel industry peer group and not less than 10 companies as the members of the general industry peer group. The Committee will also specify the amount of incentive compensation that will be awarded for levels of Nucor’s return on average invested capital when ranked against the respective peer group members.

If Nucor has no reported net earnings for a performance period, no incentive compensation will be awarded under the LTIP. In addition, the Committee may reduce incentive compensation awards in its discretion so long as the same percentage reduction is made to each senior officer’s incentive compensation award.

The value of 50% of the shares comprising a senior officer’s award under the LTIP will be paid in cash at the end of the performance period. The remaining 50% of the shares comprising the senior officer’s award will be paid to the senior officer in the form of restricted shares of Nucor’s common stock. One-third of these restricted shares will become vested upon each of the first three anniversaries of the award date, provided the senior officer remains employed through each vesting date, or,

34

if earlier, upon the senior officer’s attainment of age 55, death or disability. Senior officers have the opportunity to defer payment of the restricted stock portion of the performance award under the LTIP until the senior officer’s retirement or other termination of employment.

Federal Income Tax Consequences

A cash award under either of the plans will be taxable to the senior officer when paid. Shares of Nucor common stock awarded under the LTIP will be taxable to the senior officer when the shares become vested in the senior officer unless the senior officer elects under Section 83(b) of the Code to recognize taxable income earlier when the shares are awarded. If a senior officer elects to defer an award under either of the plans, the senior officer will recognize taxable income when the Nucor common stock resulting from the deferral is paid to the senior officer following retirement or other termination of employment. All awards under the plans should qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code that is fully deductible by Nucor for federal income tax purposes.

Share Authorization

When the plans were approved by the stockholders in 2003, Nucor reserved 1,000,000 shares of common stock for issuance under the plans. As of February 29, 2008 (after adjustment for two 2 for 1 stock splits that have occurred since 2003), 2,000,615 shares of stock remain available for awards under the plans. As of February 29, 2008, the closing price of the Nucor’s common stock was $64.57. Stockholders are not being asked to approve an increase in the number of shares available for issuance under the plans.

Amendment and Termination

The Board of Directors may, at any time and from time to time, amend, modify or terminate the plans subject to approval by the stockholders of the Company if such approval is necessary or deemed advisable under tax, securities or other applicable laws, policies or regulations.

Vote Required

Nucor’s Board of Directors recommends a vote FOR approval of the amended and restated AIP and LTIP. Unless otherwise specified, proxies will be voted FOR the amended and restated AIP and LTIP. The affirmative vote of the holders of a majority of Nucor’s common stock present or represented at the meeting is required to adopt the amended and restated AIP and LTIP.

PROPOSAL 4

STOCKHOLDER PROPOSAL

We have been notified that the United Brotherhood of Carpenters Pension Fund (the “Union”) intends to present the proposal set forth below for consideration at the annual meeting. The address and number of shares of Nucor common stock held by the Union 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.

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

“Director Election Majority Vote Standard Proposal

Resolved:    That the shareholders of Nucor Corporation (“Company”) hereby request that the Board of Directors initiate the appropriate process to amend the Company’s governance documents (certificate of incorporation or bylaws) to provide that director nominees shall be elected by the affirmative vote of the majority of votes cast at an annual meeting of shareholders, with a plurality vote standard retained for contested director elections, that is, when the number of director nominees exceeds the number of board seats.

Supporting Statement:    In order to provide shareholders a meaningful role in director elections, our Company’s director election vote standard should be changed to a majority vote standard. A majority vote standard would require that a nominee receive a majority of the votes cast in order to be elected. The standard is particularly well-suited for the vast majority of director elections in which only board nominated candidates are on the ballot. We believe that a majority vote standard in board elections would establish a challenging vote standard for board nominees and improve the performance of individual directors and entire boards. Our Company presently uses a plurality vote standard in all director elections. Under the plurality vote standard, a nominee for the board can be elected with as little as a single affirmative vote, even if a substantial majority of the votes cast are “withheld” from the nominee.

In response to strong shareholder support for a majority vote standard in director elections, an increasing number of the nation’s leading companies, including Intel, General Electric, Motorola, Hewlett-Packard, Morgan Stanley, Wal-Mart, Home Depot, Gannett, Marathon Oil, and recently Pfizer have adopted a majority vote standard in company bylaws or articles of incorporation. Additionally, these companies have adopted director resignation policies in their bylaws or corporate governance policies to address post-election issues related to the status of director nominees that fail to win election. Other companies, including our Company, have responded only partially to the call for change by simply adopting post-election director resignation policies that set procedures for addressing the status of director nominees that receive more “withhold” votes than “for” votes.

We believe that a post-election director resignation policy without a majority vote standard in company bylaws or articles is an inadequate reform. The critical first step in establishing a meaningful majority vote policy is the adoption of a majority vote standard. With a majority vote standard in place, the board can then consider action on developing post-election procedures to address the status of directors that fail to win election. A majority vote standard combined with a post-election director resignation policy would establish a meaningful right for shareholders to elect directors, and reserve for the board an important post-election role in determining the continued status of an unelected director. We feel that this combination of the majority vote standard with a post-election policy represents a true majority vote standard.”

Board of Directors’ Statement in Opposition to the Proposal

Nucor’s board of directors recommends a vote AGAINST this proposal. The Union presented substantially similar proposals at each of the last two annual meetings of Nucor stockholders, and on both occasions the proposals were defeated by Nucor’s stockholders. Notwithstanding the clear vote of our stockholders, the Union has presented its proposal again this year.

We believe that Nucor’s existing Corporate Governance Principle increases director accountability and addresses the Union’s concerns about giving stockholders a meaningful role in the director election process. The Corporate Governance Principle, which is set forth elsewhere in this proxy statement under the heading “Election of Directors,” provides that any nominee for director in an uncontested election who receives a greater number of votes “withheld” from his or her election than votes “for” such election shall promptly tender his or her resignation for consideration by the Governance and

36

Nominating Committee. As the Union acknowledges, this Corporate Governance Principle gives the Board of Directors appropriate flexibility to deal with the complex issue of how to respond if a Nucor director in an uncontested election receives a greater number of votes “withheld” from his or her election than votes “for” such election. Recent amendments to the Delaware General Corporation Law enhancing the enforceability of director resignations (by allowing them to be made effective upon the happening of a future event, coupled with authority to make them irreversible) will serve to strengthen the efficacy of Nucor’s Corporate Governance Principle.

A Task Force of the American Bar Association Committee on Corporate Law studied the benefits and detriments associated with a majority vote standard for the election of directors, and decided not to recommend a majority voting standard for directors, stating:

“The Committee believes that it is not advisable to alter the existing plurality default rule. Although the Committee is mindful of the criticisms of plurality voting, the Committee is currently persuaded that the potential negative consequences of failed elections, combined with the uncertainty of applying an untested voting standard as the default rule for public corporations, warrants the retention of the plurality voting rule.”

Retaining the plurality vote standard, which is used by almost all public companies in the United States, is also particularly advisable in Nucor’s case because its stockholders have the ability to express their preferences by cumulating their votes. Cumulative voting, which most public companies do not allow, gives Nucor’s stockholders unique leverage in voting on the election of directors. It allows stockholders to cast all of their available votes in director elections for a single director nominee, thereby enhancing the voting power of minority stockholders. The Nucor Governance Principle, unlike the proposal, has the benefit of not interfering with cumulative voting in director elections. While the rules governing director elections are well understood when cumulative voting rights are exercised under a plurality vote standard, cumulative voting under a majority vote standard presents technical and legal issues for which there is no precedent. These difficulties have led the American Bar Association Committee on Corporate Laws, the Council of Institutional Investors and the Institutional Stockholder Services Institute for Corporate Governance to conclude that majority voting should not apply to public companies that allow cumulative voting.

The Union argues that under the plurality vote standard a director could be elected with “a single affirmative vote, even if a substantial majority of the votes cast are ‘withheld’ from the nominee.” However, that remote, theoretical possibility does not accurately reflect the actual results experienced by Nucor using the plurality standard for director elections. In the past four years, Nucor directors have, on average, received from our stockholders the affirmative vote of 98.44% of the shares voted in director elections. In fact, no director nominee has received less than 97.48% of the votes cast.

The Union further argues that a majority vote standard would “improve the performance of individual directors and entire boards.” However, the management team at Nucor, under the direction of the current Board of Directors, has delivered to the Company and its stockholders the following performance over the past four years:

• For the fourth consecutive year, Nucor’s Chairman, President and Chief Executive Officer, Daniel R. DiMicco, has been named to the annual list of “America’s Best CEO’s” by Institutional Investor magazine;

• Net income increased from $64.8 million in 2003 to $1.47 billion in 2007 (an increase of 2,169%);

• Earnings per share (fully diluted) increased from $0.21 in 2003 to $4.94 in 2007 (an increase of 2,252%);

• Stock price increased from $14.00 at year end 2003 to $59.22 at year end 2007 (an increase of 323%);

• Cash dividends paid to stockholders increased from $61.8 million in 2003 to $726.1 million in 2007 (an increase of 1,075%);

• During 2007, Nucor returned to our stockholders an additional $754.0 million by repurchasing approximately 14.1 million shares of our common stock;

• In 2007 alone, Nucor returned approximately $1.5 billion in cash to our stockholders via dividends and share repurchases;

(The earnings per share and stock price numbers above have been adjusted to reflect the 2 for 1 stock splits declared by the Board in 2004 and 2006.)

The Union’s proposal makes a generic, one-size-fits all argument with respect to director elections. This approach is neither necessary nor appropriate for Nucor. Under the current plurality vote standard, Nucor’s stockholders have consistently and overwhelmingly elected a board comprised of highly qualified directors from diverse backgrounds. These directors, and the management team selected by them, have delivered impressive performance and outstanding stockholder value. It is hard to conceive how the Union’s proposal could improve such performance. Your Board recommends a vote AGAINST this proposal.

OTHER MATTERS

Discretionary Voting by Proxy Holders

Nucor’s Board of Directors does not intend to present any matters at the 2008 annual meeting of stockholders other than as set forth above and knows of no other matter to be brought before the meeting. However, if any other matter comes before the meeting, or any adjournment, the matter may be excluded by Nucor as untimely or the persons named in the enclosed proxy may vote such proxy on the matter according to their best judgment.

Stockholder Proposals

Any stockholder proposal intended to be included in Nucor’s proxy statement for its 2009 annual meeting of stockholders must be received by Nucor not later than November 26, 2008. Any stockholder proposal intended to be presented at the 2009 annual meeting of stockholders, but that will not be included in the proxy statement, must be received by Nucor no more than 90 days but at least 60 days before the date of such meeting. The 2009 annual meeting of stockholders is expected to be held on May 14, 2009. Based on the estimated meeting date, any proposals received earlier than February 13, 2009 or later than March 15, 2009 may be excluded from the meeting. Proposals should be addressed to the attention of A. Rae Eagle, Corporate Secretary, at our executive offices, 1915 Rexford Road, Charlotte, North Carolina 28211 or faxed to her attention at (704) 943-7207.

Solicitation and Expenses

Nucor will bear the entire cost of this proxy solicitation, including the preparation, printing and mailing of the proxy statement, the proxy and any additional soliciting materials sent by Nucor to stockholders. Nucor has retained the services of Georgeson Shareholder Communications Inc. (“GSC”) to assist in the solicitation of proxies from the Company’s stockholders. The fees to be paid to GSC by the Company for these services are not expected to exceed $10,000, plus reasonable out-of-pocket expenses. Further, the Company may reimburse brokerage firms and other persons representing beneficial owners of shares for reasonable expenses incurred by them in forwarding proxy soliciting materials to such beneficial owners. In addition to solicitations by mail, certain of the Company’s directors, officers and regular employees, without additional remuneration, may solicit proxies by telephone, facsimile and personal interviews. Solicitation by officers and employees of Nucor may also be made of some stockholders in person or by mail, telephone or facsimile following the original solicitation.

Delivery of Proxy Statements

As permitted by the Securities and Exchange Act of 1934, as amended, only one copy of the proxy statement and annual report is being delivered to stockholders residing at the same address, unless such stockholders have notified the Company of their desire to receive multiple copies of the proxy statement.

The Company will promptly deliver, upon oral or written request, a separate copy of the proxy statement and annual report to any stockholder residing at an address to which only one copy was mailed. Requests for additional copies and/or requests for multiple copies of the proxy statement and annual report in the future should be directed to Nucor’s Corporate Secretary at our executive offices.

Stockholders residing at the same address and currently receiving multiple copies of the proxy statement and annual report may contact Nucor’s Corporate Secretary at our executive offices to request that only a single copy of the proxy statement and annual report be mailed in the future.

ARTICLE IV

PERFORMANCE AWARDS

4.1 Performance Awards

(a) Maximum Performance Awards.    The maximum Performance Award that may be made to an Eligible Employee for a Performance Period shall be three hundred percent (300%) of the Eligible Employee’s Compensation for the Performance Period. Seventy-five percent (75%) of the maximum Performance Award for a Performance Period (i.e., 225% of the Eligible Employee’s Compensation for the Performance Period) shall be available for award based on the Company’s Return on Average Stockholders’ Equity or Other Performance Criteria selected by the Committee for the Performance Period in accordance with Section 4.1(b). Twenty-five percent (25%) of the maximum Performance Award for a Performance Period (i.e., 75% of the Eligible Employee’s Compensation for the Performance Period) shall be available for award based on the Company’s relative Revenue Growth for the Performance Period in accordance with Section 4.1(c).

(b) Performance Awards Based on Return on Average Stockholders’ Equity (or Other Performance Criteria Selected by the Committee).     The maximum Performance Award of two hundred twenty-five percent (225%) of each Eligible Employee’s Compensation for a Performance Period shall be awarded under this Section 4.1(b) if the Company’s Return on Average Stockholders’ Equity for the Performance Period equals or exceeds twenty percent (20%) (or, if the Committee has selected Other Performance Criteria for such Performance Period, the Company’s level of performance under such Other Performance Criteria equals or exceeds the level of performance designated by the Committee in writing during the first ninety (90) days of the Performance Period required for the maximum Performance Award). Not later than ninety (90) days after the beginning of each Performance Period, the Committee shall designate, in writing, a threshold Return on Average Stockholders’ Equity for the Performance Period of not less three percent (3%) and not more than seven percent (7%) (or such other threshold Return on Average Stockholders’ Equity or threshold level of performance under Other Performance Criteria selected by the Committee for such Performance Period) which must be achieved by the Company before any Performance Award may be made under this Section 4.1(b) for the Performance Period. In the event the threshold Return on Average Stockholders’ Equity (or threshold level of performance under Other Performance Criteria) is achieved by the Company for a Performance Period, a Performance Award of twenty percent (20%) (or other percentage selected by the Committee during the first ninety (90) days of the Performance Period) of each Eligible Employee’s Compensation for the Performance Period shall be awarded under this Section 4.1(b). In the event the Return on Average Stockholders’ Equity (or the Company’s performance level under Other Performance Criteria designated by the Committee) for a Performance Period exceeds the threshold performance level for the Performance Period but is less than twenty percent (20%) (or such other percentage or other level of performance under Other Performance Criteria designated by the Committee for the award of the maximum Performance Award for the Performance Period), the amount of the Performance Award, expressed as a percentage of each Eligible Employee’s Compensation for the Performance Period, under this Section 4.1(b) for the Performance Period shall be determined by linear interpolation.

(c) Performance Awards Based on Relative Revenue Growth.    Not later than ninety (90) days after the beginning of each Performance Period, the Committee shall designate, in writing, the amounts of the Performance Awards that will be made to each Eligible Employee, expressed as a percentage of the Eligible Employee’s Compensation for the Performance Period up to the maximum Performance Award of seventy-five percent (75%) of the Eligible Employee’s Compensation that may be awarded under this Section 4.1(c), for levels of Revenue Growth for the Performance Period when ranked against the revenue growth of the members of the Peer Group for the Performance Period, provided, however, the Committee’s designation of the amount of the Performance Award for each rank shall provide approximately linear progression from the minimum to the maximum award that may be made under this Section 4.1(c). The Company’s Peer Group ranking under this Section 4.1(c) and the corresponding annual Performance Awards shall be based on the most recent four (4) fiscal quarters of available financial information for a Peer Group member.

A-5

(d) Reduction or Forfeiture of Performance Awards.     Notwithstanding the foregoing provisions of this Section 4.1:

(i) if the Company has no reported net earnings for a Performance Period, no Performance Awards will be made with respect to the Performance Period; and

(ii) the Committee in its sole and exclusive discretion may reduce (including a reduction to zero) the amount of the Performance Awards otherwise payable to Eligible Employees under the Plan for a Performance Period, provided the same percentage reduction is made to all of the Performance Awards otherwise payable for the Performance Period.

4.2 Performance Award Payments

Subject to an Eligible Employee’s election in accordance with Section 4.3 to defer the payment of a Performance Award, an Eligible Employee’s Performance Award shall be paid by the Company to the Eligible Employee in cash, less applicable payroll and withholding taxes, within thirty (30) days after the later of (i) the completion of the independent audit of the Company’s financial statements for the Performance Period or (ii) the date the Committee certifies in writing the amount of Performance Awards payable under Section 4.1. In no event, however, shall payment of a Performance Award be made later than two and one-half (2 ¹/2) months after the end of the Performance Period for the Performance Award.

4.3 Deferrals of Performance Awards

(a) Deferral Agreement.    Each Eligible Employee may elect, by entering into a Deferral Agreement with the Company, to defer any portion up to fifty percent (50%) (in increments of ten percent (10%)) of the Performance Award otherwise payable to the Eligible Employee for a Performance Period. To be effective to defer the payment of a Performance Award, an Eligible Employee must complete and return a Deferral Agreement to the Company in accordance with procedures established by the Committee before the beginning of the Performance Period. For the avoidance of doubt, an Employee who first becomes an Eligible Employee during a Performance Period shall not be permitted to enter into a Deferral Agreement for the deferral of a Performance Award for such Performance Period. The amount of any Performance Award that is deferred pursuant to the Eligible Employee’s Deferral Agreement is referred to in the Plan as the Deferral Amount.

An Eligible Employee’s Deferral Agreement shall be effective for one Performance Period. Therefore, an Eligible Employee must complete and sign a Deferral Agreement and return the agreement to the representative of the Company designated by the Committee before the beginning of each Performance Period for which a deferral of a Performance Award is intended to be made.

(b) Deferral Accounts; Deferral Incentive.     An Eligible Employee’s Deferral Amount shall be converted to a number of common stock units determined by dividing the Deferral Amount by the closing price at which shares of the Company’s common stock are sold regular way on the New York Stock Exchange on the date the Deferral Amount would otherwise be paid to the Eligible Employee. Such common stock units shall be credited to a Deferral Account established and maintained on the books and records of the Company. In the event an Eligible Employee defers a Performance Award under the Plan, the Company shall credit a Deferral Incentive in the form of additional common stock units to the Eligible Employee’s Deferral Account. The number of common stock units comprising the Deferral Incentive for an Eligible Employee shall be determined by multiplying twenty-five percent (25%) by the number of common stock units resulting from the conversion of the Eligible Employee’s Deferral Amount into common stock units.

(c) Dividend Equivalent Payments; Adjustments to Common Stock Units.    The Company shall pay to each Eligible Employee in cash, less applicable payroll and withholding taxes, within thirty (30) days after the payment date of any cash dividend with respect to shares of the Company’s common stock a dividend equivalent payment equal to the number of common stock units credited to the Eligible Employee’s Deferral Account as of the record date for such dividend multiplied by the per share amount of the dividend.

In the event a dividend with respect to shares of the Company’s common stock shall be declared and paid in additional shares or in the event the outstanding shares of the Company’s common stock shall be changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation or changed into or exchanged for cash or property or the right to receive cash or property, then the Committee shall in its discretion equitably adjust the common stock units credited to the Deferral Accounts under the Plan to prevent substantial dilution or enlargement of the rights of Eligible Employees under the Plan.

A-6

(d) Vesting.    An Eligible Employee shall be fully vested in the portion of the Eligible Employee’s Deferral Account attributable to the Eligible Employee’s Deferral Amounts. An Eligible Employee shall become fully vested in the portion of the Eligible Employee’s Deferral Account attributable to the Company’s Deferral Incentives upon attainment of age fifty-five (55) while employed by the Company or a Subsidiary or in the event the Eligible Employee dies or becomes disabled while employed by the Company or a Subsidiary. In the event an Eligible Employee terminates employment prior to attaining age fifty-five (55) for any reason other than death or disability, the portion of the Eligible Employee’s Deferral Account that is not vested shall be forfeited.

(e) Payment of Deferral Accounts.    The vested portion of an Eligible Employee’s Deferral Account shall be paid to the Eligible Employee no earlier than fifteen (15) days and no later than ninety (90) days after the Eligible Employee’s separation from service. The form of payment shall be one share of the Company’s common stock for each common stock unit and cash for any fractional unit credited to the vested portion of the Deferral Account. Notwithstanding the foregoing, in no event will distribution be made to an Eligible Employee who is a “specified employee,” within the meaning of Code Section 409A(a)(2)(B)(i) and the regulations thereunder, prior to the date which is six months after such Eligible Employee’s separation from service or, if earlier, such Eligible Employee’s death.

In accordance with procedures established by the Committee, but in no event later than the later of (i) December 31, 2008 or (ii) the date an Eligible Employee enters into his or her first Deferral Agreement with the Company under the Plan, the Eligible Employee may elect a single sum payment of the Eligible Employee’s Deferral Account or payment in installments over a term certain of not more than five (5) years. In the event an Eligible Employee fails to make a valid method of payment election, distribution of the Eligible Employee’s Deferral Account shall be made in a single sum payment of shares of Company common stock and cash for any fractional unit credited to the vested portion of the Deferral Account.

(f) Payment Following Death.    An Eligible Employee may designate and change at any time the Beneficiary who is to receive distribution of the vested portion of the Participant’s Deferral Account in the event of the Eligible Employee’s death. Any such designation or change shall not be effective until received by the representative of the Company designated by the Committee. If an Eligible Employee has not properly designated a Beneficiary, if for any reason such designation shall not be legally effective, or if the designated Beneficiary shall predecease the Eligible Employee, then the Eligible Employee’s estate shall be treated as the Beneficiary.

In the event of an Eligible Employee’s death prior to distribution of all common stock units credited to the Eligible Employee’s Deferral Account, the Eligible Employee’s Beneficiary shall receive a distribution of the vested portion of such units (in the form of shares of Company common stock and cash for any fractional unit credited to the Deferral Account) as soon as practicable following the Participant’s death in a single sum payment.

A-7

ARTICLE V

MISCELLANEOUS

5.1 Amendment or Termination

5.2 Assignability

Eligible Employees shall not alienate, assign, sell, transfer, pledge, encumber, attach, mortgage, or otherwise hypothecate or convey in advance of actual receipt the amounts, if any, payable hereunder. No part of the amounts payable hereunder shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony, or separate maintenance, nor shall any person have any other claim to any benefit payable under this Plan as a result of a divorce or the Eligible Employee’s, or any other person’s, bankruptcy or insolvency.

5.3 Source of Benefits

The Company shall make any cash payments due under the terms of this Plan directly from its assets or from any trust that the Company may choose to establish and maintain from time to time. Shares of the Company’s common stock that may be issued under the Plan may be either authorized and unissued shares or shares which have been reacquired by the Company. Nothing contained in this Plan shall give or be deemed to give any Eligible Employee or any other person any interest in any property of any such trust or in any property of the Company, nor shall any Eligible Employee or any other person have any right under this Plan not expressly provided by the terms hereof, as such terms may be interpreted and applied by the Committee in its discretion.

5.4 No Promise of Continued Employment

Nothing in this Plan or in any materials describing or relating to this Plan grants, nor should it be deemed to grant, any person any employment right, nor does participation in this Plan imply that any person has been employed for any specific term or duration or that any person has any right to remain in the employ of the Company.

5.5 Applicable Law

The Plan shall be construed in accordance with and governed by the laws of the State of North Carolina.

5.6 Stockholder Approval

The effectiveness of this amendment and restatement of the Plan shall be subject to its approval and ratification by the stockholders of the Company at the 2008 annual meeting of stockholders.

INTRODUCTION

Nucor Corporation hereby amends and restates in its entirety the Nucor Corporation Senior Officers Long-Term Incentive Plan to read as set forth herein. The purpose of the Plan is to provide incentive compensation to senior officers based on Nucor Corporation’s long-term performance relative to that of its principal competitors in the steel industry and of other industrial companies, consistent with the “performance based compensation” requirements of Section 162(m) of the Code.

ARTICLE II

DEFINITIONS

For purposes of the Plan, the following terms shall have the following meanings:

PERFORMANCE AWARDS

4.1 Performance Awards

(a) Maximum Performance Awards.    The maximum Performance Award that may be made to an Eligible Employee with respect to any Performance Period shall be two (2) times the Eligible Employee’s Target Performance Award for the Performance Period. All Performance Awards under the Plan shall be based on the Company’s relative Return on Average Invested Capital in accordance with Section 4.1(b).

(b) Awards Based on Relative Return on Average Invested Capital.

(i) Steel Peer Group.    Fifty percent (50%) of the maximum Performance Award for a Performance Period (i.e., 100% of the number of shares of the Company’s common stock comprising the Eligible Employee’s Target Performance Award for the Performance Period) shall be available for award based on the Company’s Return on Average Invested Capital for the Performance Period relative to the return on average invested capital of each company in the Steel Peer Group for the Performance Period. Not later than ninety (90) days after the beginning of each Performance Period, the Committee shall designate, in writing, the amounts of the Performance Awards that will be made to each Eligible Employee, expressed as a percentage of the number of shares comprising the Eligible Employee’s Target Performance Award for the Performance Period, for levels of Return on Average Invested Capital for the Performance Period when ranked against the return on average invested capital of the members of the Steel Peer Group for the Performance Period.

(ii) General Industry Group.    The remaining fifty percent (50%) of the maximum Performance Award for a Performance Period (i.e., 100% of the number of shares of the Company’s common stock comprising the Eligible Employee’s Target Performance Award for the Performance Period) shall be available for award based on the Company’s Return on Average Invested Capital for the Performance Period relative to the return on average invested capital of each company in the General Industry Group for the Performance Period. Not later than ninety (90) days after the beginning of each Performance Period, the Committee shall designate, in writing, the amounts of the Performance Awards that will be made to each Eligible Employee, expressed as a percentage of the number of shares comprising the Eligible Employee’s Target Performance Award for the Performance Period, for levels of Return on Average Invested Capital for the Performance Period when ranked against the return on average invested capital of the members of the General Industry Group for the Performance Period.

The Committee’s designation of the amount of the Performance Award for the Company’s rankings against the Steel Peer Group and the General Industry Group shall provide approximately equal progression in the amount of the award from the minimum to the maximum amount that may be awarded under Sections 4.1(b)(i) and (ii). The Company’s Steel Peer Group and General Industry Group rankings shall be based on the most recent available financial information for the members of the Steel Peer Group and General Industry Group.

(c) Reduction or Forfeiture of Performance Awards.    Notwithstanding the foregoing provisions of this Section 4.1:

(i) if the Company has no reported net earnings for a Performance Period, no Performance Awards will be made with respect to the Performance Period;

(ii) the Committee in its sole and exclusive discretion may reduce (including a reduction to zero) the amount of the Performance Awards otherwise payable to Eligible Employees under the Plan for a Performance Period, provided the same percentage reduction is made to all of the Performance Awards otherwise payable for the Performance Period; and

B-5

(iii) if the employment of an Eligible Employee is terminated during a Performance Period prior to the Eligible Employee’s attainment of age fifty-five (55) for any reason other than the Eligible Employee’s death or disability, the Eligible Employee shall not receive any Performance Award under the Plan for the Performance Period.

4.2 Performance Award Payments

An Eligible Employee’s Performance Award shall be paid by the Company to the Eligible Employee within thirty (30) days after the later of (i) the completion of the independent audit of the Company’s financial statements for the Performance Period or (ii) the date the Committee certifies in writing the amount of Performance Awards payable under Section 4.1. In no event, however, shall payment of a Performance Award be made later than two and one-half (2 ¹/2) months after the end of the Performance Period for the Performance Award. The value of fifty percent (50%) of the shares comprising an Eligible Employee’s Performance Award for a Performance Period, determined by multiplying the number of such shares by the closing price at which shares of the Company’s common stock are sold regular way on the New York Stock Exchange on the last trading day of the Performance Period, shall be paid to the Eligible Employee in cash, less applicable payroll and withholding taxes. The remaining fifty percent (50%) of the shares comprising the Eligible Employee’s Performance Award shall be rounded down to the next lower whole number of shares. Such whole number of shares shall constitute the Eligible Employee’s “Restricted Stock Performance Award” and shall be delivered to the Eligible Employee, unless the Eligible Employee makes an election in accordance with Section 4.3 to defer payment of the Restricted Stock Performance Award. The Restricted Stock Performance Award shares shall become vested in the Eligible Employee upon the Eligible Employee’s attainment of age fifty-five (55) while employed by the Company or a Subsidiary, in the event the Eligible Employee dies or becomes disabled while employed by the Company or a Subsidiary or, if earlier, in installments based on the Eligible Employee’s continued employment with the Company or a Subsidiary through each of the following vesting dates:

Vesting Date	Vested Portion of Restricted Stock Performance Award
1st anniversary of payment date	33-1/3%
2nd anniversary of payment date	66-2/3%
3rd anniversary of payment date	100%

In the event an Eligible Employee’s employment with the Company and its subsidiaries terminates for any reason, the Eligible Employee shall, for no consideration, forfeit to the Company coincident with such termination all shares in the Restricted Stock Performance Award that have not become vested in the Eligible Employee.

4.3 Deferrals of Restricted Stock Performance Awards

(a) Deferral Agreement.    Each Eligible Employee may elect, by entering into a Deferral Agreement with the Company, to defer payment of all (and not less than all) of the Restricted Stock Performance Award otherwise payable to the Eligible Employee for a Performance Period. To be effective to defer the payment of a Restricted Stock Performance Award, an Eligible Employee must complete and return a Deferral Agreement to the Company in accordance with procedures established by the Committee for such purpose on or before the date that is six (6) months before the end of the Performance Period; provided, however, an Employee who first becomes an Eligible Employee during a Performance Period shall not be permitted to enter into a Deferral Agreement for the deferral of a Restricted Stock Performance Award for such Performance Period.

An Eligible Employee’s Deferral Agreement shall be effective for one Performance Period. Therefore, an Eligible Employee must complete and sign a Deferral Agreement and return the agreement to the representative of the Company designated by the Committee on or before the date that is six (6) months before the end of the Performance Period for which a deferral of a Restricted Stock Performance Award is intended to be made.

(b) Deferral Accounts.    In the event an Eligible Employee defers the payment of a Restricted Stock Performance Award, the number of shares comprising such award shall be converted into an equivalent number of common stock units, and such units shall be credited to a Deferral Account established and maintained in the Eligible Employee’s name on the books and records of the Company.

(c) Dividend Equivalent Payments; Adjustments to Common Stock Units.    The Company shall pay to each Eligible Employee in cash, less applicable payroll and withholding taxes, within thirty (30) days after the payment date of any cash dividend with respect to shares of the Company’s common stock a dividend equivalent payment equal to the number of common stock units credited to the Eligible Employee’s Deferral Account as of the record date for such dividend multiplied by the per share amount of the dividend.

B-6

In the event a dividend with respect to shares of the Company’s common stock shall be declared and paid in additional shares or in the event the outstanding shares of the Company’s common stock shall be changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation or changed into or exchanged for cash or property or the right to receive cash or property, then the Committee shall in its discretion equitably adjust the common stock units credited to the Deferral Accounts under the Plan to prevent substantial dilution or enlargement of the rights of Eligible Employees under the Plan.

(d) Vesting.    An Eligible Employee shall become vested in the common stock units credited to the Eligible Employee’s Deferral Account in accordance with the vesting provisions of Section 4.2 that would have applied to the Restricted Stock Performance Award shares from which such units were derived. In the event an Eligible Employee terminates employment prior to attaining age fifty-five (55) for any reason other than death or disability, the common stock units credited to the Eligible Employee’s Deferral Account that are not vested shall be forfeited.

(e) Payment of Deferral Accounts.    The vested portion of an Eligible Employee’s Deferral Account shall be paid to the Eligible Employee no earlier than fifteen (15) days and no later than ninety (90) days after the Eligible Employee’s separation from service. The form of payment shall be one share of the Company’s common stock for each common stock unit and cash for any fractional unit credited to the vested portion of the Deferral Account. Notwithstanding the foregoing, in no event will distribution be made to an Eligible Employee who is a “specified employee,” within the meaning of Code Section 409A(a)(2)(B)(i) and the regulations thereunder, prior to the date which is six months after such Eligible Employee’s separation from service or, if earlier, such Eligible Employee’s death.

In accordance with procedures established by the Committee, but in no event later than the later of (i) December 31, 2008 or (ii) the date an Eligible Employee enters into his or her first Deferral Agreement with the Company under the Plan, the Eligible Employee may elect a single sum payment of the Eligible Employee’s Deferral Account or payment in installments over a term certain of not more than five (5) years. In the event an Eligible Employee fails to make a valid method of payment election, distribution of the Eligible Employee’s Deferral account shall be made in a single sum payment of shares of Company common stock and cash for any fractional unit credited to the Deferral Account.

(f) Payment Following Death.    An Eligible Employee may designate and change at any time the Beneficiary who is to receive distribution of the vested portion of the Participant’s Deferral Account in the event of the Eligible Employee’s death. Any such designation or change shall not be effective until received by the representative of the Company designated by the Committee. If an Eligible Employee has not properly designated a Beneficiary, if for any reason such designation shall not be legally effective, or if the designated Beneficiary shall predecease the Eligible Employee, then the Eligible Employee’s estate shall be treated as the Beneficiary.

In the event of an Eligible Employee’s death prior to distribution of all common stock units credited to the Eligible Employee’s Deferral Account, the Eligible Employee’s Beneficiary shall receive a distribution of the vested portion of such units (in the form of shares of Company common stock and cash for any fractional unit credited to the Deferral Account) as soon as practicable following the Participant’s death in a single sum payment.
