This Policy also applies to any and all transactions in the securities of another company by an Employee or Board Member while in possession of Material, Non-public Information about such company that was learned of by virtue of their relationship with the Company.

Transactions that may be necessary or justifiable for independent reasons (such as the need to raise money for an emergency) are neither an exception to this Policy nor a safeguard against prosecution for violation of insider trading laws.

• Transact in Company Securities during any Special No Trade Period that the Employee has been notified is in effect;

• Disclose Material, Non-public Information regarding the Company to other Employees (except on a need-to-know basis), family, friends, or any other person, firm, or entity (this prohibition is to ensure that no Employee becomes a “tipper,” liable for the trading activities of his or her “tippee” and such disclosures may also violate confidentiality obligations to or of the Company);

• Recommend or suggest that any person engage in transactions in Company Securities or in the securities of any other company while in possession of Material, Non-public Information about the Company or such other company learned while performing his or her job at the Company; or

• Transact in the securities of another company while in possession of Material, Non- public Information about such company learned while performing his or her job at the Company.

Insiders – Insiders are subject to all of the restrictions set forth above for “All Employees” and Insiders shall not:

• Transact in Company Securities when Material, Non-public Information about the Company has been included in the Company’s public filings with the SEC or in a press release broadly disseminated to the general public until the second full business day after any such filing or press release is made (e.g., when the public disclosure by press release or filing with the SEC is made before the securities markets open on a Monday, Insiders may not begin to Transact in Company Securities until the opening of the securities markets on Wednesday; if, however, the public disclosure is made on a Monday at any time after the securities markets open, Insiders may not begin to Transact in Company Securities until the opening of the securities markets on Thursday).

• Transact in Company Securities during the No Trade Period;

• Use Company Securities as collateral in a margin account with a broker-dealer;

• Engage in a short sale of Company Securities or any Derivatives Transaction; or

• Vary from the above restrictions without the pre-clearance of any proposed variance from the Corporate Secretary or her designee.

Exceptions – The restrictions listed above for “All Employees,” “Insiders,” and “Section 16 Insiders” will not apply to transactions pursuant to a Trading Plan.

E. REPURCHASES OF COMPANY SECURITIES UNDER ANY STOCK REPURCHASE PROGRAM

F. TRADING PLANS

Without regard to the restrictions listed above, Employees and Insiders may buy or sell Company Securities pursuant to a single predetermined plan that complies with SEC Rule 10b5-1 and Nucor’s Rule 10b5-1 Trading Plan Guidelines. To obtain the guidelines and discuss the process for implementing a Trading Plan, please contact the Corporate Secretary.

G. POST-TERMINATION TRANSACTIONS

This Policy continues to apply to an Employee’s or Board Member’s transactions in Company Securities even after his or her service or employment relationship with the Company has been terminated as follows: if any Employee or Board Member is aware of Material, Non-public Information about the Company when his or her service or employment relationship terminates, he or she may not trade in Company Securities until the earlier to occur of such Material, Non-public Information becoming public or becoming no longer Material. For purposes of this Policy, information is considered Non-public until two full business days after its public disclosure.

If an Employee or Board member is uncertain or unable to determine whether certain Non-public Information remains Material after his or her service or employment relationship with the Company is terminated, he or she should contact the Corporate Secretary.

H. CONSEQUENCES

Failure to abide by this Policy will result in sanctions. These may include removal or dismissal, as the circumstances may warrant, for cause.

Trading on Material, Non-public Information is a crime subject to fines up to five million dollars and jail terms for individuals of up to 20 years. In addition, the SEC may seek civil penalties of three

times the profit gained or loss avoided, and violators may also be subject to civil liability to private plaintiffs. These penalties may apply even if the individual violator is not a Board Member, Section 16 Insider, Insider Employee, or officer of the Company.

Employers and other controlling persons are also at risk under federal law and may be fined if they fail to take reasonable steps to prevent illegal trading in Company Securities by persons under their control.

Any criminal or civil sanctions, penalties, fines, and other costs incurred by an Employee or Board Member for violation of any laws governing the trading of securities will be the sole responsibility of the individual; and the Company will not cover or indemnify any individual for such costs.

I. REPORTING OF VIOLATIONS

Anyone who knows, or has reason to believe, that this Policy has been, or is about to be violated, should immediately bring the actual or potential violation to the attention of the Corporate Secretary or the General Counsel.

J. COMPANY ASSISTANCE

It is not possible in this Policy to cover all of the possible situations one may encounter regarding trading in Company Securities or in the securities of another company and sharing information about the Company or such other company with others. Therefore, the Company encourages each Employee and Board Member to discuss specific questions and concerns with the Corporate Secretary. Please remember, however, that the ultimate responsibility for complying with this Policy and applicable laws and avoiding improper transactions rests with each individual covered by this Policy. In any case, all Employees and Board Members are expected to use good judgment when engaging in transactions in Company Securities or in the securities of another company and when sharing information about the Company or such other company with others. If any doubt exists whether a particular situation requires refraining from buying or selling Company Securities or the securities of another company or sharing information about the Company or such other company with others, the most prudent course of action is to refrain from engaging in such activities.

K. CAUTIONARY STATEMENT

The Company encourages Employees and Board Members, who may be interested, to own Company Securities as a long-term investment at levels consistent with their individual financial circumstances and risk bearing abilities. However, all Employees and Board Members must recognize that trading in Company Securities may be prohibited at a particular time because of the existence of Material, Non-public Information. Any Employee or Board Member purchasing Company Securities must consider the inherent risk that a sale of Company Securities could be prohibited at a time when he or she might desire to sell them. The next opportunity to sell might not

occur until after an extended period, during which time the market price of Company Securities might decline.
