SUBJECT TO COMPLETION, DATED AUGUST 19, 2021

PROSPECTUS

Nucor Corporation

Offer to Exchange

Up to $439,312,000 of 2.979% Notes due 2055

That Have Been Registered Under

the Securities Act of 1933, As Amended (“New Notes”)

For a Like Principal Amount of

2.979% Notes due 2055

That Have Not Been Registered Under

the Securities Act of 1933, As Amended (“Existing Notes”)

• We are offering to exchange up to $439,312,000 aggregate principal amount of our New Notes for a like principal amount of our outstanding Existing Notes that are validly tendered and not validly withdrawn prior to the expiration of the exchange offer.

• The terms of the New Notes are substantially identical in all material respects to the terms of the Existing Notes, except that the New Notes will be registered under the Securities Act of 1933, as amended (the “Securities Act”), and, therefore, will be freely tradable and will not contain restrictions on transfer, registration rights or provisions for the payment of additional interest.

• Interest on the New Notes will accrue from the date interest on the Existing Notes was most recently paid, at the rate of 2.979% per annum, and will be payable semi-annually in arrears on June 15 and December 15 of each year to the holders of record on the immediately preceding June 1 and December 1, respectively.

• We will not receive any proceeds from the issuance of the New Notes in the exchange offer.

• The exchange offer will expire at 5:00 p.m., New York City time, on                 , 2021, unless extended at our option. We do not currently intend to extend the Expiration Date (as defined in this prospectus) unless required to do so by applicable law as described under “The Exchange Offer—Expiration Date; Amendments.”

• You should carefully review the procedures for tendering Existing Notes under the heading “The Exchange Offer—Procedures for Tendering Existing Notes” in this prospectus. If you do not comply with these procedures, we are not obligated to exchange your Existing Notes for New Notes.

• If you currently hold Existing Notes and fail to validly tender them, or withdraw them prior to the expiration of the exchange offer, then you will continue to hold unregistered Existing Notes and your ability to transfer them will be subject to restrictions on transfer, which could adversely affect your ability to transfer Existing Notes.

• The New Notes generally will be freely transferable but will also be new securities for which there will not initially be an established trading market. We do not intend to apply for the listing of the New Notes on any securities exchange or for the quotation of the New Notes on any automated dealer quotation system. Accordingly, there can be no assurance as to the development or liquidity of any market for the New Notes.

Each broker-dealer that receives New Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, such broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Notes received in exchange for Existing Notes where such Existing Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period of 180 days after the last Exchange Date (as defined in this prospectus), we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. Please read “Plan of Distribution.”

See “Risk Factors” beginning on page 11 of this prospectus for a discussion of factors that you should consider before participating in the exchange offer.

Neither we nor our board of directors make any recommendation to holders of Existing Notes as to whether to tender or refrain from tendering all or any portion of their Existing Notes pursuant to the exchange offer. Moreover, no one has been authorized to make any such recommendation.

Neither the Securities and Exchange Commission (the “SEC” or the “Commission”) nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is                 , 2021.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any applicable prospectus supplement and any related free writing prospectus and the documents incorporated by reference herein and therein may include “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Statements that do not relate strictly to historical facts are forward-looking statements. Statements containing words such as “anticipate,” “believe,” “expect,” “intend,” “project,” “may,” “will,” “should,” “could” and similar expressions are intended to identify those forward-looking statements. These forward-looking statements reflect our best judgment based on current information, and, although we base these statements on circumstances that we believe to be reasonable when made, there can be no assurance that future events will not affect the accuracy of such forward-looking information. As such, the forward-looking statements are not guarantees of future performance, and actual results may vary materially from the projected results and expectations discussed. Factors that might cause our actual results to differ materially from those anticipated in forward-looking statements include, but are not limited to: (i) competitive pressure on sales and pricing, including pressure from imports and substitute materials; (ii) U.S. and foreign trade policies affecting steel imports or exports; (iii) the sensitivity of the results of our operations to prevailing market steel prices and changes in the supply and cost of raw materials, including pig iron, iron ore and scrap steel; (iv) the availability and cost of electricity and natural gas, which could negatively affect our cost of steel production or result in a delay or cancellation of existing or future drilling within our natural gas drilling programs; (v) critical equipment failures and business interruptions; (vi) market demand for steel products, which, in the case of many of our products, is driven by the level of nonresidential construction activity in the United States; (vii) impairment in the recorded value of inventory, equity investments, fixed assets, goodwill or other long-lived assets; (viii) uncertainties surrounding the global economy, including excess world capacity for steel production; (ix) fluctuations in currency conversion rates; (x) significant changes in laws or government regulations affecting environmental compliance, including legislation and regulations that result in greater regulation of greenhouse gas emissions that could increase our energy costs, capital expenditures and operating costs or cause one or more of our permits to be revoked or make it more difficult to obtain permit modifications; (xi) the cyclical nature of the steel industry; (xii) capital investments and their impact on our performance; (xiii) our safety performance; and (xiv) the impact of the COVID-19 pandemic and any variants of the virus.

Additional information regarding the risks and uncertainties which may affect our business operations and financial performance can be found in our filings with the SEC. Caution should be taken not to place undue reliance on the forward-looking statements included in this prospectus. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law.

The Exchange Offer

Securities to be Exchanged

In December 2020, we issued $439,312,000 aggregate principal amount of 2.979% Notes due 2055 (CUSIP Nos. 670346 AT2 and U66980 AC4 / ISIN Nos. US670346AT26 and USU66980AC46) (“Existing Notes”) in transactions that were exempt from, or not subject to, the registration requirements under the Securities Act. In connection with the issuance of the Existing Notes, the Company entered into a registration rights agreement (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Company agreed to, among other things, consummate an exchange offer to exchange the Existing Notes for a new issue of notes with terms substantially identical in all material respects to the terms of the Existing Notes registered under the Securities Act within 365 days of the first issuance of the Existing Notes. As of the date of this prospectus, all $439,312,000 aggregate principal amount of Existing Notes are outstanding.

The Exchange Offer

We are offering to exchange all of our outstanding Existing Notes for a like principal amount of our 2.979% Notes due 2055 that will be registered under the Securities Act (“New Notes”). The terms of the New Notes are substantially identical in all material respects to the terms of the Existing Notes, except that the New Notes will be registered under the Securities Act, and, therefore, will be freely tradable and will not contain restrictions on transfer, registration rights or provisions for the payment of additional interest. The Existing Notes are governed by, and were issued pursuant to, the terms of an indenture, dated as of August 19, 2014, as amended or supplemented by a first supplemental indenture, dated as of April 26, 2018, a second supplemental indenture, dated as of May 22, 2020, and a third supplemental indenture, dated as of December 7, 2020, in each case, between the Company and U.S. Bank National Association, as trustee (the “Trustee”) (together, the “Indenture”). The New Notes will be governed by the terms of the Indenture and, together with any Existing Notes outstanding after the completion of the exchange offer, will constitute a single series of debt securities under the Indenture. The Existing Notes may be tendered only in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. We will issue New Notes in exchange for all Existing Notes that are validly tendered and not withdrawn prior to the expiration of the exchange offer. We will cause the exchange to be effected promptly after the Expiration Date.

Resales of New Notes Without Further Registration; Prospectus Delivery

Based on Commission staff interpretations given to other, unrelated issuers in other exchange offers, we believe that holders of the New Notes who are not broker-dealers can offer for resale, resell and otherwise transfer the New Notes without complying with the registration and prospectus delivery requirements of the Securities Act, if: •   the holders acquire the New Notes in the exchange offer in the ordinary course of their business; •   the holders are not engaged in, do not intend to engage in, are not participating in, and have no arrangement or understanding with any person to participate in a distribution (within the meaning of the Securities Act) of the New Notes issued to them in the exchange offer; •   the holders are not “affiliates” (as defined in Rule 405 under the Securities Act) of Nucor; and •   the holders are not broker-dealers tendering Existing Notes acquired directly from us for their own accounts. By tendering your Existing Notes, you are representing to us that you satisfy each of these conditions. See “—Procedures for Tendering Existing Notes.” If you do not satisfy any of these conditions, you cannot rely on the position of the Commission staff set forth in the no-action letters referred to below and you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of your New Notes. We will not seek a Commission staff interpretation in connection with the exchange offer and cannot assure you that the Commission staff would make a similar interpretation with respect to the exchange offer. If our belief is wrong, you could incur liability under the Securities Act. We do not and will not assume, or indemnify you against, any Securities Act liability you may incur.

Restrictions on Resales by Broker-Dealers

Under the Securities Act, each broker-dealer that receives New Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Notes. We have agreed that, for a period of 180 days after the last Exchange Date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

Expiration Date; Extension of Tender Period; Termination; and Amendment	The exchange offer will expire at 5:00 p.m., New York City time, on                 , 2021 (the “Expiration Date”), unless extended at our option, in which case the term “Expiration Date” will mean the latest date to which the exchange offer is extended. You must tender your outstanding Existing Notes prior to this time if you want to participate in the exchange offer. We may terminate the exchange offer in the event of circumstances described beginning on page 13 under the heading “The Exchange Offer.” We have the right to amend any of the terms of the exchange offer subject to our obligations under the Registration Rights Agreement and applicable law.
Conditions to the Exchange Offer	The Registration Rights Agreement does not require us to accept Existing Notes for exchange if (i) the exchange offer would violate any applicable law, regulation or interpretation by the staff of the Commission or (ii) any action or proceeding has been instituted or threatened in any court or by or before any governmental agency relating to the exchange offer which, in our judgment, could reasonably be expected to impair our ability to proceed with the exchange offer. The exchange offer is not conditioned on a minimum aggregate principal amount of Existing Notes being tendered by the holders of the Existing Notes. Please read the section of this prospectus entitled “The Exchange Offer—Conditions” for more information about the conditions to the exchange offer.
Procedures for Tendering Existing Notes	A holder who wishes to tender Existing Notes in the exchange offer must do either of the following prior to 5:00 p.m., New York City time, on the Expiration Date: •   if the Existing Notes are tendered under the book-entry transfer procedures described under “The Exchange Offer—Book-Entry Transfers; Tender of Existing Notes Using DTC’s ATOP,” must transmit to the Exchange Agent (as defined in this prospectus) an agent’s message using The Depository Trust Company’s (“DTC”) Automated Tender Offer Program (“ATOP”); or •   if the holder does not elect to transmit an agent’s message through DTC’s ATOP, the holder must properly complete, sign and date the letter of transmittal, including all other documents required by the letter of transmittal; have the signature on the letter of transmittal

guaranteed if the letter of transmittal so requires; and mail or deliver the letter of transmittal and other required documents to the Exchange Agent at the address listed on the back cover page of this prospectus.

In addition, prior to 5:00 p.m., New York City time, on the Expiration Date, the Exchange Agent must receive a timely confirmation of book-entry transfer of the Existing Notes into the Exchange Agent’s account at DTC under the procedures for book-entry transfers described in this prospectus, along with either an agent’s message transmitted through ATOP or a properly completed, signed and dated letter of transmittal, or manually signed facsimile thereof, together with any signature guarantees and other documents required by the instructions in the letter of transmittal, and any other required documentation.

By tendering, you will represent to us that, among other things:

•   any New Notes to be received by you in the exchange offer will be acquired in the ordinary course of your business;

•   at the time of the commencement of the exchange offer, you are not participating, and have no arrangement or understanding with any person to participate, in a distribution (within the meaning of the Securities Act) of the New Notes in violation of the provisions of the Securities Act;

•   you are not an “affiliate” (as defined in Rule 405 under the Securities Act) of Nucor;

•   if you are not a broker-dealer, that you are not engaged in, and do not intend to engage in, a distribution of the New Notes; and

•   if you are a broker-dealer that will receive New Notes for your own account in exchange for Existing Notes that were acquired as a result of market-making activities or other trading activities, then you will deliver, or, to the extent permitted by applicable law, make available to purchasers, a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes.

5

	Do not send letters of transmittal to us, the Trustee or DTC. Send these documents only to the Exchange Agent. For more information on tendering your Existing Notes, please refer to the sections in this prospectus entitled “The Exchange Offer—Terms of the Exchange Offer,” “The Exchange Offer—Procedures for Tendering Existing Notes” and “Description of the New Notes—Book-Entry System, Delivery and Form.”

Guaranteed Delivery Procedures for Tendering Existing Notes	None.

If we do not accept any of your outstanding Existing Notes for exchange, the Exchange Agent will return them to you promptly after the expiration or termination of the exchange offer without any expense to you.
Fees and Expenses	We will bear expenses related to the exchange offer. Please refer to the section of this prospectus entitled “The Exchange Offer—Fees and Expenses.”
Use of Proceeds	We will not receive any proceeds from the issuance of the New Notes in the exchange offer. See “Use of Proceeds.”

6

Material U.S. Federal Income Tax Consequences	An exchange of Existing Notes for New Notes pursuant to the exchange offer will not be treated as a taxable exchange or other taxable event for U.S. federal income tax purposes. Accordingly, there will be no U.S. federal income tax consequences to holders who exchange their Existing Notes for New Notes in connection with the exchange offer and any such holder will have the same adjusted tax basis and holding period in the New Notes as it had in the Existing Notes immediately before the exchange. See “Material U.S. Federal Income Tax Consequences.”
Exchange Agent and Information Agent	D.F. King & Co., Inc. is serving as the exchange agent (the “Exchange Agent”) and the information agent (the “Information Agent”) in connection with the exchange offer. The address and telephone numbers of D.F. King & Co., Inc. are listed on the back cover page of this prospectus.
Legal Requirements to Exchange Offer	There are no federal or state regulatory requirements that must be complied with in connection with the exchange offer, other than registration under the Securities Act of the New Notes.
Legal Limitation	We are not making an offer to sell, nor are we soliciting an offer to buy, securities in any jurisdiction in which the offer or sale is not permitted.

Risk Factors You should carefully consider the information set forth in the section of this prospectus entitled “Risk Factors” as well as the other information included in or incorporated by reference into this prospectus before deciding whether to participate in the exchange offer.

10

RISK FACTORS

Participating in the exchange offer involves a high degree of risk. Before making a decision as to whether to participate in the exchange offer, you should carefully consider the risks discussed below and all of the information contained in or incorporated by reference into this prospectus, including the matters discussed under the section entitled “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020. Additional risks not currently known to us or that we currently deem immaterial may also adversely affect our business and operations. If any of these risks were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. As a result, the trading price of the Existing Notes and the New Notes could decline, perhaps significantly, and you could lose all or part of your investment. The risks discussed below also include forward-looking statements and our actual results may differ substantially from those discussed in these forward-looking statements. See “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to the Exchange Offer

Failure to exchange your Existing Notes may have adverse consequences to you.

If you do not exchange your Existing Notes for New Notes in the exchange offer, your Existing Notes will continue to be subject to the restrictions on transfer described in the legend on your Existing Notes. Because we anticipate that most holders of Existing Notes will elect to exchange their Existing Notes, we expect that the liquidity of the market for any Existing Notes remaining after the completion of the exchange offer will be substantially limited. This reduction in liquidity may, in turn, reduce the market price, and increase the price volatility, of the Existing Notes. There is a risk that an active trading market in the unexchanged Existing Notes will not exist, develop or be maintained and we cannot give you any assurances regarding the prices at which the unexchanged Existing Notes may trade in the future.

In general, the Existing Notes may not be offered or sold unless they are registered under the Securities Act. However, you may offer or sell your Existing Notes under an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. After the exchange offer is completed, you will not be entitled to any exchange or registration rights with respect to your Existing Notes, except in limited circumstances. The exchange offer is not conditioned on a minimum aggregate principal amount of Existing Notes being tendered by the holders of the Existing Notes.

The exchange offer will expire at 5:00 p.m., New York City time, on the Expiration Date, unless extended at our option. Issuance of the New Notes in exchange for the Existing Notes pursuant to the exchange offer will be made following the prior satisfaction, or waiver, of the conditions set forth in “The Exchange Offer—Conditions” and only after timely receipt by the Exchange Agent of Existing Notes as set forth in “The Exchange Offer—Procedures for Tendering Existing Notes.” Therefore, holders of Existing Notes desiring to tender their Existing Notes in exchange for New Notes should allow sufficient time to ensure timely delivery of all required documentation, if applicable. Neither we, the Exchange Agent, nor any other person is under any duty to give notification of defects or irregularities with respect to the tenders of Existing Notes for exchange. Existing Notes that may be tendered in the exchange offer, but which are not validly tendered or are validly tendered and timely withdrawn will remain outstanding following the consummation of the exchange offer.

Certain participants in the exchange offer must deliver a prospectus in connection with resales of the New Notes.

Based on certain no-action letters issued by the staff of the Commission to other, unrelated issuers in other exchange offers, we believe that you may offer for resale, resell or otherwise transfer the New Notes without complying with the registration and prospectus delivery requirements of the Securities Act. However, in some instances described in this prospectus under “Plan of Distribution,” you will remain obligated to comply with the

11

registration and prospectus delivery requirements of the Securities Act to transfer your New Notes. In these cases, if you transfer any New Notes issued to you in the exchange offer without delivering a prospectus meeting the requirements of the Securities Act or without qualifying for an exemption from the registration requirements of the Securities Act, you may incur liability under the Securities Act. We do not and will not assume, or indemnify you against, any Securities Act liability you may incur.

Risks Related to the New Notes

The New Notes will be structurally subordinated to all obligations of our subsidiaries.

The New Notes will not be guaranteed by our subsidiaries, and, therefore, they will be structurally subordinated to all existing and future indebtedness and liabilities of our subsidiaries. As of July 3, 2021, our subsidiaries had approximately $100.7 million aggregate principal amount of indebtedness, consisting of trade credit financing arrangements. Except as described under “Description of the New Notes—Covenants Applicable to the New Notes,” the Indenture does not limit any of our subsidiaries from incurring more indebtedness or issuing more securities and does not contain financial or similar restrictions on any of our subsidiaries. Our rights and the rights of our creditors, including holders of the New Notes, to participate in any distribution of assets of any of our subsidiaries, upon the subsidiary’s liquidation or reorganization or otherwise, will be structurally subordinated to the claims of the subsidiary’s creditors, except to the extent that we or any of our creditors may be a creditor of that subsidiary. In the event of a bankruptcy, liquidation or dissolution of a subsidiary, following payment by the subsidiary of its liabilities, the subsidiary may not have sufficient assets to make payments to us.

Despite current indebtedness levels, we may still incur more debt. The incurrence of additional debt could further exacerbate the risks associated with our indebtedness.

Subject to certain limitations, the terms of the instruments governing our indebtedness and the indentures governing our debt securities permit, and the terms of the New Notes offered hereby will permit, us and our subsidiaries to incur additional debt. If new debt is added to our or any such subsidiary’s current debt levels, it may become more difficult for us to satisfy our obligations with respect to the New Notes and limit our ability to borrow additional amounts to fund working capital, capital expenditures and acquisitions and execute our growth strategy. We may also become more vulnerable to adverse changes in general economic and industry activity and in our business by limiting our flexibility in planning for, and making it more difficult for us to react quickly to, changing conditions. Further, in certain circumstances, we may not be able to refinance our debt on favorable terms, or at all.

The New Notes lack a developed trading market, and such a market may never develop. The trading price for the New Notes may be adversely affected by credit market conditions.

The New Notes will be a new issue of securities for which there will not initially be an established trading market. We do not intend to apply for the listing of the New Notes on any securities exchange or for the quotation of the New Notes on any automated dealer quotation system. Consequently, there can be no assurance that an active trading market will develop for the New Notes, nor any assurance regarding the ability of holders to sell their New Notes or the price at which such holders may be able to sell their New Notes. If a trading market were to develop, the New Notes could trade at prices that may be higher or lower than the initial offering price depending on many factors, including, among other things, prevailing interest rates, our financial results, any decline in our creditworthiness and the market for similar securities.

The trading market for the New Notes will be affected by general credit market conditions, which in recent periods have been marked by significant volatility and price reductions, including for debt issued by investment-grade companies. If an active trading market for the New Notes is not developed or sustained, the market prices and liquidity of the New Notes may be adversely affected.

THE EXCHANGE OFFER

Background and Reasons for the Exchange Offer

We issued the Existing Notes that are subject to the exchange offer in December 2020 in transactions that were exempt from, or not subject to, the registration requirements of the Securities Act. On December 7, 2020, simultaneously with the first issuance of the Existing Notes that are subject to the exchange offer, we entered into the Registration Rights Agreement with BofA Securities, Inc., J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, Deutsche Bank Securities Inc., RBC Capital Markets, LLC, U.S. Bancorp Investments, Inc., Siebert Williams Shank & Co., LLC, Fifth Third Securities, Inc., PNC Capital Markets LLC and MUFG Securities Americas Inc., under which we agreed to offer to exchange the Existing Notes for a new issue of notes with terms substantially identical in all material respects to the terms of the Existing Notes registered under the Securities Act.

In particular, under the Registration Rights Agreement, we agreed, for the benefit of the holders of the Existing Notes, at our cost, to use our commercially reasonable efforts:

• to cause to be filed with the Commission, and to become effective, a registration statement with respect to the exchange offer for the Existing Notes;

• to consummate the exchange offer within 365 days after the first issuance of the Existing Notes; and

• if requested by one or more Participating Broker-Dealers (as defined below), to keep the exchange offer registration statement effective until 180 days after the last date of acceptance for exchange (each, an “Exchange Date”) of the Existing Notes for use by such Participating Broker-Dealers.

The exchange offer being conducted with this prospectus, if consummated within the required time period, will satisfy our obligations under the Registration Rights Agreement, except in limited circumstances described elsewhere in this prospectus. This prospectus, together with the related letter of transmittal, is being sent to all beneficial holders of Existing Notes known to us.

Promptly after the registration statement of which this prospectus is a part has been declared effective by the Commission, we will offer the New Notes in exchange for surrender of the Existing Notes. We will keep the exchange offer open for a period of at least 20 business days (or longer if required by applicable law) from the date notice of the exchange offer is sent or made available to the holders of the Existing Notes. For each Existing Note validly tendered to us pursuant to the exchange offer and not withdrawn by the holder thereof prior to the Expiration Date, the holder of each Existing Note will receive a New Note having a principal amount equal to that of the tendered Existing Note. Interest on each New Note will accrue from the date interest on the Existing Notes was most recently paid.

Based on an interpretation of the Securities Act by the staff of the Commission set forth in several no-action letters to other, unrelated issuers in other exchange offers, and subject to the immediately following sentence, we believe that the New Notes issued pursuant to the exchange offer may be offered for resale, resold and otherwise transferred by holders thereof without further compliance with the registration and prospectus delivery provisions of the Securities Act. However, any purchaser of Existing Notes who is an “affiliate” (as defined in Rule 405 under the Securities Act) of Nucor, or who intends to participate in the exchange offer for the purpose of distributing the New Notes (i) will not be able to rely on the interpretation by the staff of the Commission set forth in the no-action letters of the Commission’s staff, (ii) will not be able to tender Existing Notes in the exchange offer and (iii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of the Existing Notes, unless such sale or transfer is made pursuant to an exemption from such requirements.

13

Each holder of the Existing Notes who wishes to exchange Existing Notes for New Notes in the exchange offer will be required to make certain representations, including that:

• any New Notes to be received by the holder of Existing Notes in the exchange offer will be acquired in the ordinary course of the holder’s business;

• at the time of the commencement of the exchange offer, the holder is not participating, and has no arrangement or understanding with any person to participate, in a distribution (within the meaning of the Securities Act) of the New Notes in violation of the provisions of the Securities Act;

• the holder is not an “affiliate” (as defined in Rule 405 under the Securities Act) of Nucor;

• if the holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, a distribution of the New Notes; and

• if the holder is a broker-dealer (a “Participating Broker-Dealer”) that will receive New Notes for its own account in exchange for Existing Notes that were acquired as a result of market-making activities or other trading activities, then such holder will deliver, or, to the extent permitted by applicable law, make available to purchasers, a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes.

The Commission has taken the position that Participating Broker-Dealers may fulfill their prospectus delivery requirements with respect to the New Notes by using the prospectus contained in the effective exchange offer registration statement. We will allow Participating Broker-Dealers and other persons, if any, subject to similar prospectus delivery requirements to use the prospectus contained in the effective exchange offer registration statement in connection with the resale of such New Notes, subject to limitations set forth in the Registration Rights Agreement.

If (i) for any reason the exchange offer is not completed within 365 days after the first issuance of the Existing Notes or (ii) following such date the Company receives a written request (a “Shelf Request”) from certain parties, including any holder of Existing Notes that participates in the exchange offer who does not receive freely transferable New Notes in exchange for tendered Existing Notes, the Company will use its commercially reasonable efforts to cause to become effective a shelf registration statement providing for the sale of all the Existing Notes by the holders thereof; provided that (1) such holder has delivered a completed and signed notice and questionnaire and provided such other information regarding such holder and the proposed disposition by such holder of such Existing Notes and other documentation necessary to effectuate the proposed disposition as the Company may from time to time reasonably request in writing, and, if necessary, the shelf registration statement has been amended to reflect such information, and (2) the Company will be under no obligation to file any such shelf registration statement before it is obligated to file the registration statement of which this prospectus is a part. The Company agreed to use its commercially reasonable efforts to keep the shelf registration statement continuously effective until the date on which the Existing Notes covered thereby cease to be registrable securities under the Registration Rights Agreement. The Company also agreed to use its commercially reasonable efforts to supplement or amend the shelf registration statement, the related prospectus and any related free writing prospectus, if required, and to use its commercially reasonable efforts to cause any such amendment to become effective, if required, and such shelf registration statement, prospectus or free writing prospectus, as the case may be, to become usable as soon as thereafter practicable.

We will, in the event that a shelf registration statement is filed, provide to each holder whose Existing Notes are registered under such shelf registration statement copies of the prospectus that is a part of such shelf registration statement, notify each such holder and its counsel when, among other things, such shelf registration statement has become effective and take certain other actions as are required to permit unrestricted resales of the Existing Notes. A holder that sells Existing Notes pursuant to a shelf registration statement for the Existing Notes will be (i) required to make certain representations to us (as described more fully in the Registration Rights Agreement), (ii) required to be named as a selling security holder of the Existing Notes in the related prospectus

14

and to deliver a prospectus to purchasers, (iii) subject to certain of the civil liability provisions under the Securities Act in connection with such sales and (iv) bound by the provisions of the Registration Rights Agreement that are applicable to such a holder (including certain indemnification obligations).

If (i) the exchange offer of the New Notes for all Existing Notes validly tendered in accordance with the terms of the exchange offer is not completed on or prior to the 365th day after the first issuance of the Existing Notes or, if a shelf registration statement is required, such shelf registration statement is not declared effective on or prior to the 180th day after the later of (1) the 365th day after the first issuance of the Existing Notes and (2) the date on which the Company receives a duly executed Shelf Request or (ii) if applicable, a shelf registration statement has been declared effective and such shelf registration statement ceases to be effective or the prospectus contained therein ceases to be usable for resales of registrable securities (1) on more than two occasions of at least 30 consecutive days during the required effectiveness period or (2) at any time in any 12-month period during the required effectiveness period and such failure to remain effective or be usable exists for more than 90 days (whether or not consecutive) in any 12-month period (each such event referred to in clauses (i) and (ii), a “Registration Default”), then the interest rate on the Existing Notes will be increased by (a) 0.25% per annum for the first 90-day period beginning on the day immediately following such Registration Default and (b) an additional 0.25% per annum with respect to each subsequent 90-day period, in each case until and including the date such Registration Default ends, up to a maximum increase of 1.00% per annum. A Registration Default ends with respect to any Existing Notes when such Existing Notes cease to be registrable securities under the Registration Rights Agreement or, if earlier, (x) in the case of a Registration Default under clause (i) of the definition thereof, when the exchange offer is completed or when the shelf registration statement covering such registrable securities becomes effective or (y) in the case of a Registration Default under clause (ii) of the definition thereof, when the shelf registration statement again becomes effective or the applicable prospectus again becomes usable.

The form and terms of the New Notes are substantially identical in all material respects to the form and terms of the Existing Notes. The New Notes will be registered under the Securities Act. The Existing Notes are not registered under the Securities Act. As a result, the New Notes issued in the exchange offer will not bear legends restricting their transfer and will not contain the registration rights and provisions for the payment of additional interest contained in the Existing Notes. Upon the completion of the exchange offer, you will not be entitled to any payment of additional interest on your Existing Notes or any further registration rights under the Registration Rights Agreement except in limited circumstances. The exchange offer is not extended to holders of Existing Notes in any jurisdiction where the exchange offer does not comply with the applicable securities or blue sky laws of that jurisdiction.

In this section entitled “The Exchange Offer,” the term “holder” means any person whose Existing Notes are held of record by DTC or its nominee and who wants to deliver these Existing Notes by book-entry transfer at DTC.

Terms of the Exchange Offer

We are offering to exchange up to $439,312,000 aggregate principal amount of our 2.979% Notes due 2055 that have been registered under the Securities Act for a like principal amount of our outstanding 2.979% Notes due 2055 that have not been registered under the Securities Act.

Upon the terms and subject to the conditions set forth in this prospectus and in the related letter of transmittal, we will accept all Existing Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the Expiration Date, unless extended at our option. We will issue $1,000 principal amount of New Notes in exchange for each $1,000 principal amount of outstanding Existing Notes we accept in the exchange offer. You may tender some or all of your Existing Notes under the exchange offer at your option. The exchange offer is not conditioned on a minimum aggregate principal amount of Existing Notes being tendered by the holders of the Existing Notes.

15

The form and terms of the New Notes are substantially identical in all material respects to the form and terms of the Existing Notes, except that:

• the New Notes will be registered under the Securities Act and, thus, will not be subject to restrictions on transfer or bear legends restricting their transfer; and

• the New Notes will not contain registration rights provisions and will not provide for the payment of additional interest for failure to comply with the Registration Rights Agreement.

After the completion of the exchange offer, if at all, the New Notes will evidence the same series of debt securities as the Existing Notes and will be issued under, and be entitled to the benefits of, the Indenture. Interest on the New Notes will accrue from the date interest on the Existing Notes was most recently paid. Accordingly, registered holders of New Notes on the record date for the first interest payment date following the completion of the exchange offer will receive interest accrued from the date it was most recently paid. However, if that record date occurs prior to the completion of the exchange offer, then the interest payable for the first interest payment date following the completion of the exchange offer will be paid to the registered holders of the Existing Notes on that record date.

In connection with the exchange offer, you do not have any appraisal or dissenters’ rights under the General Corporation Law of the State of Delaware or the Indenture. We intend to conduct the exchange offer in accordance with the Registration Rights Agreement and the applicable requirements of the Exchange Act, and the rules and regulations of the SEC.

We will be deemed to have accepted validly tendered Existing Notes for exchange when, as and if we have given notice of our acceptance to the Exchange Agent. The Exchange Agent will act as agent for the tendering holders for the purpose of receiving the New Notes from us. If we do not accept any tendered Existing Notes because of an invalid tender or for any other reason, the Exchange Agent will return certificates for any unaccepted Existing Notes without expense to the tendering holder promptly after the Expiration Date.

Minimum Authorized Denominations

Existing Notes can be tendered only in principal amounts equal to the minimum authorized denomination of $2,000 and integral multiples of $1,000 in excess thereof. New Notes will be issued only in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Expiration Date; Amendments

The exchange offer will expire at 5:00 p.m., New York City time, on the Expiration Date, unless extended at our option, in which case the term “Expiration Date” will mean the latest date to which the exchange offer is extended. If we determine to extend the exchange offer, we will notify the Exchange Agent of any extension and give each registered holder notice of the extension by means of a press release or other public announcement, which notice shall include the approximate number of Existing Notes tendered to date, before 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

We reserve the right, in our sole discretion, to extend the exchange offer or to amend or terminate the exchange offer if any of the conditions described below under “—Conditions” have not been satisfied or waived by giving notice to the Exchange Agent of the extension, amendment or termination. Further, we reserve the right, in our sole discretion, to amend the terms of the exchange offer in any manner. We will, as promptly as practicable, give written notice of any extension, amendment or termination of the exchange offer to the holders of the Existing Notes.

The minimum period during which the exchange offer will remain open following material changes in the terms of the exchange offer or in the information concerning the exchange offer will depend upon the facts and circumstances of such changes, including the relative materiality of the changes.

16

Without limiting the manner in which we may choose to make a public announcement of any extension, amendment or termination of the exchange offer, we will not be obligated to publish, advertise or otherwise communicate any announcement, other than by making a timely release to an appropriate news agency.

Procedures for Tendering Existing Notes

The tender by a holder of Existing Notes, as set forth below, and our acceptance of the Existing Notes will constitute a binding agreement between us and the holder in accordance with the terms and subject to the conditions set forth in this prospectus and in the related letter of transmittal. A holder who wishes to tender Existing Notes in the exchange offer must do either of the following prior to 5:00 p.m., New York City time, on the Expiration Date:

• if the Existing Notes are tendered under the book-entry transfer procedures described below under “—Book-Entry Transfers; Tender of Existing Notes Using DTC’s ATOP,” transmit to the Exchange Agent an agent’s message using DTC’s ATOP; or

• if the holder does not elect to transmit an agent’s message through DTC’s ATOP, the holder must properly complete, sign and date the letter of transmittal, including all other documents required by the letter of transmittal; have the signature on the letter of transmittal guaranteed if the letter of transmittal so requires; and mail or deliver the letter of transmittal and other required documents to the Exchange Agent at the address listed on the back cover page of this prospectus.

In addition, prior to 5:00 p.m., New York City time, on the Expiration Date, the Exchange Agent must receive a timely confirmation of book-entry transfer of the Existing Notes into the Exchange Agent’s account at DTC under the procedures for book-entry transfers described below, along with either an agent’s message transmitted through ATOP or a properly completed, signed and dated letter of transmittal, or manually signed facsimile thereof, together with any signature guarantees and other documents required by the instructions in the letter of transmittal, and any other required documentation.

The term “agent’s message” means a message, transmitted by DTC and received by the Exchange Agent and forming part of the confirmation of a book-entry transfer, which states the aggregate principal amount of Existing Notes that have been tendered by such participant pursuant to the exchange offer, that DTC has received an express acknowledgment from a participant in DTC tendering Existing Notes, that such participant has received the letter of transmittal and agrees to be bound by the terms of the letter of transmittal, and that Nucor may enforce such agreement against the participant. Delivery of an agent’s message will also constitute an acknowledgment from the tendering DTC participant that the representations, warranties and agreements set forth in the letter of transmittal are true and correct.

Only a registered holder of the Existing Notes may tender the Existing Notes in the exchange offer. Delivery of Existing Notes will be deemed made, and the risk of loss of the Existing Notes will pass to the Exchange Agent, only when the agent’s message is actually received by the Exchange Agent. The method of delivery of the letter of transmittal and all other required documents to the Exchange Agent is at the holder’s election and risk. Rather than mail any of these items, Nucor recommends that holders use an overnight or hand delivery service. In all cases, holders should allow sufficient time to assure delivery to the Exchange Agent by the Expiration Date. Holders should not send the letter of transmittal to us, the Trustee or DTC.

If a letter of transmittal is completed, signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by an “Eligible Guarantor Institution” within the meaning of Rule 17Ad-15 under the Exchange Act, unless the Existing Notes surrendered for exchange are tendered:

• by a registered holder (or a participant in DTC whose name appears on a security position report listing as the holder of Existing Notes) who has not completed the box labeled “Special Issuance and Payment Instructions” or “Special Delivery Instructions” in the letter of transmittal; or

• for the account of an Eligible Guarantor Institution.

17

If the letter of transmittal is signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, these persons should so indicate when signing. Unless we waive this requirement, they should also submit evidence satisfactory to us of their authority to deliver the letter of transmittal.

Any beneficial owner of Existing Notes who is not a holder of such Existing Notes must arrange with the person who is the holder or such holder’s assignee or nominee to execute and deliver the letter of transmittal on behalf of such beneficial owner. Each of the foregoing may take considerable time. We will determine in our sole discretion all questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of Existing Notes tendered for exchange. Our determination will be final and binding on all parties. We reserve the absolute right to decline to accept any and all tenders of Existing Notes not validly tendered or any Existing Notes our acceptance for exchange of which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any defects, irregularities or conditions of tenders as to any particular Existing Notes, whether or not similar defects, irregularities or conditions are waived in the case of other tendered Existing Notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Existing Notes must be cured within the time period we determine. Neither we, the Exchange Agent nor any other person has any duty to give notification of defects or irregularities with respect to tenders of Existing Notes. In addition, neither we, the Exchange Agent nor any other person will incur any liability for failure to give you notification of defects or irregularities with respect to tenders of your Existing Notes.

By tendering, you will represent to us that, among other things:

• any New Notes to be received by you in the exchange offer will be acquired in the ordinary course of your business;

• at the time of the commencement of the exchange offer, you are not participating, and have no arrangement or understanding with any person to participate, in a distribution (within the meaning of the Securities Act) of the New Notes in violation of the provisions of the Securities Act;

• you are not an “affiliate” (as defined in Rule 405 under the Securities Act) of Nucor;

• if you are not a broker-dealer, that you are not engaged in, and do not intend to engage in, a distribution of the New Notes; and

• if you are a Participating Broker-Dealer that will receive New Notes for your own account in exchange for Existing Notes that were acquired as a result of market-making activities or other trading activities, then you will deliver, or, to the extent permitted by applicable law, make available to purchasers, a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes.

If you or the person receiving your New Notes is an “affiliate” (as defined in Rule 405 under the Securities Act) of Nucor, or intends to participate in the exchange offer for the purpose of distributing the New Notes, then you or the person receiving your New Notes (i) will not be able to rely on the interpretation by the staff of the Commission set forth in the no-action letters of the Commission’s staff, (ii) will not be able to tender Existing Notes in the exchange offer and (iii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of the Existing Notes, unless such sale or transfer is made pursuant to an exemption from such requirements.

Acceptance of Existing Notes for Exchange; Delivery of New Notes

For purposes of the exchange offer, we will be deemed to have accepted validly tendered Existing Notes for exchange when, as and if we have given notice of our acceptance to the Exchange Agent. For each Existing Note accepted for exchange, you will receive, promptly after the Expiration Date, a New Note having a principal amount equal to that of the surrendered Existing Note.

18

Guaranteed Delivery Procedures for Tendering Existing Notes

No guaranteed delivery procedures are being offered in connection with the exchange offer. Any holder must effect valid tenders of its Existing Notes at or prior to the Expiration Date in order to be eligible to receive New Notes.

Book-Entry Transfers; Tender of Existing Notes Using DTC’s ATOP

All of the Existing Notes are held in book-entry form through the facilities of DTC. We expect that the Exchange Agent will make a request promptly after the date of this prospectus to establish accounts with respect to the Existing Notes at DTC for the purpose of facilitating the exchange offer. Subject to the establishment of the accounts, any financial institution that is a participant in DTC’s system may tender Existing Notes in the exchange offer through book-entry delivery of such Existing Notes by causing DTC to transfer the Existing Notes into the Exchange Agent’s account in accordance with DTC’s procedures for such transfer.

If you desire to tender Existing Notes held in book-entry form with DTC, the Exchange Agent must receive, by the Expiration Date:

• a confirmation of book-entry transfer of your Existing Notes into the Exchange Agent’s account at DTC, and either:

• a properly completed, signed and dated letter of transmittal, or manually signed facsimile thereof, together with any signature guarantees and other documents required by the instructions in the letter of transmittal; or

• an agent’s message transmitted through ATOP; and

• any other required documentation.

DTC participants may electronically transmit their acceptance of the exchange offer by complying with DTC’s ATOP procedures. If a DTC participant participates in the exchange offer using ATOP, and also causes the transfer of book-entry Existing Notes to the Exchange Agent’s account as described above, DTC is expected to send a book-entry confirmation, including an agent’s message, to the Exchange Agent. If you use ATOP procedures to tender Existing Notes, you will not be required to deliver a letter of transmittal to the Exchange Agent, but you will be bound by its terms just as if you had signed it and be deemed to have made all the representations, warranties and agreements therein.

Withdrawal of Tenders

Tenders of Existing Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date. To withdraw a tender of Existing Notes in connection with the exchange offer, a written notice of withdrawal must be received by the Exchange Agent at its address set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date. Any such notice of withdrawal must:

• specify the name of the person who deposited the Existing Notes to be withdrawn;

• identify the Existing Notes to be withdrawn (including the certificate number(s), if any, and principal amount of such Existing Notes);

• be signed by the depositor in the same manner as the original signature on the letter of transmittal by which such Existing Notes were tendered (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the Trustee register the transfer of such Existing Notes into the name of the person withdrawing the tender; and

• specify the name in which any such Existing Notes are to be registered, if different from that of the depositor.

19

If Existing Notes have been tendered pursuant to the procedures for book-entry transfer, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Existing Notes or otherwise comply with DTC’s procedures.

We will determine in our sole discretion all questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices and our determination will be final and binding on all parties. Any Existing Notes so withdrawn will be considered not to have been validly tendered for purposes of the exchange offer, and no New Notes will be issued unless the Existing Notes withdrawn are validly re-tendered. Any Existing Notes which have been tendered but which are withdrawn or which are not accepted for exchange will be returned to the holder without cost to such holder promptly after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn Existing Notes may be re-tendered by following one of the procedures described above under “—Procedures for Tendering Existing Notes” at any time prior to the Expiration Date.

Conditions

Notwithstanding any other term of the exchange offer, we will not be required to accept Existing Notes for exchange if:

• the exchange offer would violate any applicable law, regulation or interpretation by the staff of the SEC; or

• any action or proceeding has been instituted or threatened in any court or by or before any governmental agency relating to the exchange offer which, in our judgment, could reasonably be expected to impair our ability to proceed with the exchange offer.

The conditions listed above are for our sole benefit and we may assert them regardless of the circumstances giving rise to any condition, subject to applicable law. We may waive these conditions in our sole discretion in whole or in part at any time and from time to time prior to the expiration of the exchange offer. If we waive a condition, we may be required, in order to comply with applicable securities laws, to extend the Expiration Date of the exchange offer. If we fail at any time to exercise any of the above rights, the failure will not be deemed a waiver of those rights, and those rights will be deemed ongoing rights which may be asserted at any time and from time to time prior to the expiration of the exchange offer; provided, however, that if we decide to waive a condition, we will announce such decision in a manner reasonably calculated to inform holders of the Existing Notes of such waiver.

Exchange Agent and Information Agent

D.F. King & Co., Inc. has been appointed as the Exchange Agent and the Information Agent for the exchange offer. A copy of the letter of transmittal and all correspondence in connection with the exchange offer should be sent or delivered by each holder, or a beneficial owner’s broker, dealer, commercial bank, trust company or other nominee, directly to the Exchange Agent at the address listed on the back cover page of this prospectus. Questions or requests for assistance related to the exchange offer and tender procedures and requests for additional copies of this prospectus and the related letter of transmittal should be directed to the Exchange Agent and the Information Agent at the address and telephone numbers listed on the back cover page of this prospectus. Holders of Existing Notes who are the beneficial owner but not the registered owner of the Existing Notes may also contact their broker, dealer, commercial bank, trust company or other nominee for assistance concerning the exchange offer. We will pay the Exchange Agent and the Information Agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses.

Delivery of the letter of transmittal to an address other than that of the Exchange Agent above or transmission via facsimile other than as listed on the back cover page of this prospectus will not constitute a valid delivery of the letter of transmittal.

Fees and Expenses

We will bear the expenses of the exchange offer. We will not make any payments to brokers, dealers or others soliciting acceptances of the exchange offer. The principal solicitation is being made by electronic communications; however, additional solicitations may be made by e-mail, mail, facsimile transmission, telephone or in person by the Information Agent or by our officers and other employees. You will not be charged a service fee for the exchange of your Existing Notes, but we may require you to pay any transfer or similar government taxes in certain circumstances.

Transfer Taxes

You will not be obligated to pay any transfer taxes, unless you instruct us to register New Notes in the name of, or request that Existing Notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder.

Consequences of Failure to Exchange Existing Notes

If you are eligible to participate in the exchange offer but do not tender your Existing Notes, you will no longer be able to require us to register the Existing Notes under the Securities Act, except in limited circumstances provided in the Registration Rights Agreement, or be entitled to receive any payments of additional interest under the Registration Rights Agreement. Your Existing Notes will continue to be subject to restrictions on transfer. Accordingly, you may resell the Existing Notes that are not exchanged only if registered pursuant to the Securities Act, if any exemption from registration is available, or if such registration is not required by law. We do not intend to register the Existing Notes under the Securities Act.

Accounting Treatment

The New Notes will be recorded at the same carrying value as the Existing Notes. Accordingly, we will not recognize any gain or loss on the exchange for accounting purposes.

Regulatory Approvals

We do not believe that the receipt of any material federal or state regulatory approval will be necessary in connection with the exchange offer, other than the declaration of the effectiveness of the exchange offer registration statement under the Securities Act by the Commission.

21

USE OF PROCEEDS

The exchange offer is intended to satisfy our obligations under the Registration Rights Agreement. We will not receive any proceeds from the issuance of the New Notes in the exchange offer. In consideration for issuing the New Notes as contemplated by this prospectus, we will receive Existing Notes in a like principal amount. Existing Notes surrendered in exchange for the New Notes will be retired and cancelled and will not be reissued. Accordingly, the issuance of the New Notes will not result in any change in our outstanding indebtedness.

22

DESCRIPTION OF THE NEW NOTES

The 2.979% Notes due 2055 (“New Notes”) that have been registered under the Securities Act of 1933, as amended (the “Securities Act”), will be issued under an indenture, dated as of August 19, 2014, as amended or supplemented by a first supplemental indenture, dated as of April 26, 2018, a second supplemental indenture, dated as of May 22, 2020, and a third supplemental indenture, dated as of December 7, 2020, in each case, between the Company and U.S. Bank National Association, as trustee (the “Trustee”) (together, the “Indenture”). The outstanding 2.979% Notes due 2055 (“Existing Notes”) were issued under the Indenture in transactions that were exempt from, or not subject to, the registration requirements under the Securities Act.

The following description is only a summary of the material provisions of the New Notes and the Indenture. The following description does not purport to be complete, and is subject to, and is qualified in its entirety by reference to, all of the provisions of the New Notes and the Indenture. We urge you to read the Indenture and the form of the New Notes, which you may obtain from us upon request. In this description, all references to “Nucor,” the “Company,” “we,” “us” and “our” refer only to Nucor Corporation and not to any of its subsidiaries.

The terms of the New Notes are substantially identical in all material respects to the terms of the Existing Notes, except that the New Notes are registered under the Securities Act, and the transfer restrictions, registration rights and payment of additional interest in case of non-registration applicable to the Existing Notes do not apply to the New Notes.

General

The New Notes will be issued under the Indenture. The Indenture does not limit the aggregate principal amount of debt securities (referred to as the “debt securities”) which may be issued thereunder. The original principal amount of New Notes issuable in the exchange offer is $439,312,000, which is the aggregate principal amount of all outstanding Existing Notes as of the date of this prospectus. The New Notes will be issued in fully registered book-entry form and in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

After issuance of the New Notes, we may reopen and issue additional notes from the same series by board resolution without your consent and without notifying you. Any such additional New Notes will have the same ranking, interest rate, maturity date, redemption rights and other terms as the New Notes (except the public offering price, date of issuance and, if applicable, the initial interest payment date) offered pursuant to this prospectus. Any such additional New Notes, together with the Existing Notes outstanding after the completion of the exchange offer and the New Notes offered hereby, will be consolidated with and constitute a single series of debt securities under the Indenture.

The New Notes will not have the benefit of a sinking fund.

The covenants in the Indenture may not protect you from a decline in our credit quality due to highly leveraged or other transactions in which we may engage.

Interest

Interest on the outstanding New Notes will accrue at a rate of 2.979% per annum. Interest on the New Notes will accrue from the date interest on the Existing Notes was most recently paid. Interest on the New Notes will be payable semi-annually in arrears on June 15 and December 15 of each year to the holders of record on the immediately preceding June 1 and December 1, respectively (whether or not a business day). Interest on the New Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

23

If any interest payment date, stated maturity date or earlier redemption date falls on a Saturday, a Sunday or a day on which banking institutions are authorized by law to close, then the required payment of principal of and premium, if any, and interest may be made on the next succeeding day not a Saturday, a Sunday or a day on which banking institutions are authorized by law to close, as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and after that interest payment date, stated maturity date or earlier redemption date, as the case may be.

Ranking

The New Notes will be our senior unsecured obligations and will rank equally with our existing and future senior unsecured indebtedness, including any Existing Notes that are not tendered in the exchange offer. The New Notes will be effectively subordinated to our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to all existing and future indebtedness and liabilities of our subsidiaries. After giving effect to the exchange offer and the issuance of the New Notes in connection therewith (assuming we issue New Notes in exchange for all outstanding Existing Notes, but excluding bond issuance costs, cash premiums paid and other costs of the exchange offer), as of July 3, 2021, we would have had approximately $5,388.2 million of total consolidated indebtedness and a percentage of indebtedness to total capital (which includes our short and long-term indebtedness, our finance lease obligations, Nucor stockholders’ equity and noncontrolling interests) of approximately 29.8%.

As of July 3, 2021, without giving effect to the exchange offer or the issuance of the New Notes, there were outstanding approximately $600 million aggregate principal amount of our unsecured 4.125% Notes due 2022, $500 million aggregate principal amount of our unsecured 4.000% Notes due 2023, $500 million aggregate principal amount of our unsecured 2.000% Notes due 2025, $500 million aggregate principal amount of our unsecured 3.950% Notes due 2028, $500 million aggregate principal amount of our unsecured 2.700% Notes due 2030, approximately $543.4 million aggregate principal amount of our unsecured 6.400% Notes due 2037, approximately $338.1 million aggregate principal amount of our unsecured 5.200% Notes due 2043, approximately $329.2 million aggregate principal amount of our unsecured 4.400% Notes due 2048, approximately $439.3 million aggregate principal amount of Existing Notes and approximately $1,153.2 million aggregate principal amount of unsecured indebtedness under our industrial revenue bonds. On August 4, 2021, Nucor became an obligor with respect to $197.0 million aggregate principal amount of unsecured indebtedness under our industrial revenue bonds.

Except as described under “—Covenants Applicable to the New Notes,” the Indenture does not limit us or any of our Subsidiaries (as defined below) from incurring more indebtedness or issuing more securities and does not contain financial or similar restrictions on us or any of our Subsidiaries. Our rights and the rights of our creditors, including holders of the New Notes, to participate in any distribution of assets of any of our Subsidiaries, upon the Subsidiary’s liquidation or reorganization or otherwise, will be structurally subordinated to the claims of the Subsidiary’s creditors, except to the extent that we or any of our creditors may be a creditor of that Subsidiary. As of July 3, 2021, our Subsidiaries had approximately $100.7 million aggregate principal amount of indebtedness, consisting of trade credit financing arrangements.

“Subsidiary” means an entity more than 50% of the outstanding voting interest of which is owned, directly or indirectly, by the Company or by one or more other Subsidiaries, or by the Company and one or more other Subsidiaries. For the purposes of this definition, “voting interest” in an entity means any equity interest which ordinarily has voting power for the election of directors or their equivalent.

24

Optional Redemption

At any time prior to June 15, 2055 (six months prior to the maturity date of the New Notes), the New Notes will be redeemable, in whole or in part, at any time or from time to time, at our option, at a redemption price equal to the greater of:

• 100% of the principal amount of the New Notes to be redeemed; or

• the sum of the present values of the Remaining Scheduled Payments (as defined below) on such New Notes being redeemed that would be due if the New Notes to be redeemed matured on the Par Call Date (as defined below), discounted to the redemption date on a semi-annual basis (assuming a 360-day year comprised of twelve 30-day months) at the Adjusted Treasury Rate (as defined below) (determined on the third business day preceding the redemption date),

plus, in each case, accrued and unpaid interest thereon, to, but excluding, the redemption date.

On or after June 15, 2055 (six months prior to the maturity date of the New Notes), the New Notes will be redeemable, in whole or in part, at any time or from time to time, at our option, at 100% of the principal amount of the New Notes to be redeemed, plus accrued and unpaid interest thereon, to, but excluding, the redemption date.

Notwithstanding the foregoing, installments of interest on the New Notes that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date.

“Adjusted Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (as defined below), assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for that redemption date, plus 0.20%.

“Comparable Treasury Issue” means the U.S. Treasury security selected by our choice of BofA Securities, Inc., J.P. Morgan Securities LLC or Wells Fargo Securities, LLC, and its successors, or, if such firm is unwilling or unable to select the Comparable Treasury Issue, another Reference Treasury Dealer (as defined below), as having a maturity comparable to the remaining term of the New Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the New Notes (assuming for this purpose that the New Notes matured on the Par Call Date).

“Comparable Treasury Price” means, with respect to any redemption date, the average of the Reference Treasury Dealer Quotations (as defined below) for such redemption date.

“Par Call Date” means June 15, 2055 (the date that is six months prior to the maturity date of the New Notes).

“Reference Treasury Dealer” means each of BofA Securities, Inc., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC, and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in the United States (a “Primary Treasury Dealer”) or is no longer quoting prices for U.S. Treasury securities, the Company will substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

25

“Remaining Scheduled Payments” means, with respect to each New Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such New Note, the amount of the next succeeding scheduled interest payment thereon will be deemed to be reduced by the amount of interest accrued thereon to such redemption date.

Notice of any redemption will be delivered at least 15 days but no more than 60 days before the redemption date to each registered holder of the New Notes to be redeemed. The notice of redemption for the New Notes will state, among other things, the amount of New Notes to be redeemed, the redemption date, the redemption price and the place or places that payment will be made upon presentation and surrender of New Notes to be redeemed. If less than all of the New Notes are to be redeemed, the New Notes to be redeemed shall be selected in accordance with the procedures of The Depository Trust Company (“DTC”). Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the New Notes or portions thereof called for redemption.

Change of Control Offer to Purchase

If a Change of Control Triggering Event (as defined below) occurs, holders of the New Notes may require us to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of their New Notes at a purchase price of 101% of the principal amount, plus accrued and unpaid interest, if any, on such New Notes, to, but excluding, the purchase date (unless a notice of redemption has been delivered within 30 days after such Change of Control Triggering Event stating that all of the New Notes will be redeemed as described under “—Optional Redemption”). We will be required to deliver to holders of the New Notes a notice describing the transaction or transactions constituting the Change of Control Triggering Event and offering to repurchase the New Notes. The notice must be delivered within 30 days after any Change of Control Triggering Event, and the repurchase must occur no earlier than 30 days and no later than 60 days after the date the notice is delivered.

On the date specified for repurchase of the New Notes, we will, to the extent lawful:

• accept for purchase all properly tendered New Notes or portions of New Notes;

• deposit with the paying agent the required payment for all properly tendered New Notes or portions of New Notes; and

• deliver to the Trustee the repurchased New Notes, accompanied by an officer’s certificate stating, among other things, the aggregate principal amount of repurchased New Notes.

We will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations applicable to the repurchase of the New Notes. To the extent that these requirements conflict with the provisions requiring repurchase of the New Notes in the Indenture, we will comply with such requirements instead of the repurchase provisions and will not be considered to have breached our obligations under the Indenture with respect to repurchasing the New Notes. Additionally, if an event of default exists under the Indenture (which is unrelated to the repurchase provisions of the New Notes), including events of default arising with respect to other issues of debt securities, we will not be required to repurchase the New Notes notwithstanding these repurchase provisions.

We will not be required to comply with the obligations relating to repurchasing the New Notes if a third party instead satisfies them.

For purposes of the repurchase provisions of the New Notes, the following terms will be applicable:

“Change of Control” means the occurrence of any of the following: (i) the consummation of any transaction (including, without limitation, any merger or consolidation) resulting in any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) (other than us or one of our Subsidiaries) becoming the “beneficial owner”

26

(as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of our Voting Stock (as defined below) or other Voting Stock into which our Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than the number of shares; (ii) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in a transaction or a series of related transactions, of all or substantially all of our assets and the assets of our Subsidiaries, taken as a whole, to one or more “persons” (as that term is used in Section 13(d)(3) of the Exchange Act) (other than us or one of our Subsidiaries); or (iii) the first day on which a majority of the members of our board of directors are not Continuing Directors (as defined below). Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control if (i) we become a direct or indirect wholly owned Subsidiary of a holding company and (ii)(1) immediately following that transaction, the direct or indirect holders of the Voting Stock of such holding company are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (2) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event (as defined below).

“Continuing Director” means, as of any date of determination, any member of our board of directors who (i) was a member of the board of directors on the date the New Notes were issued or (ii) was nominated for election, elected or appointed to the board of directors by or with the approval (given either before or after such member’s nomination, election or appointment) of a majority of the Continuing Directors who were members of the board of directors at the time of such nomination, election or appointment (either by a specific vote or by approval of our proxy statement in which such member was named as a nominee for election as a director, without objection to such nomination).

“Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s (as defined below) and BBB– (or the equivalent) by S&P (as defined below), and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies (as defined below) selected by us.

“Moody’s” means Moody’s Investors Service, Inc.

“Rating Agencies” means (i) each of Moody’s and S&P and (ii) if either Moody’s or S&P ceases to rate the New Notes or fails to make a rating of the New Notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) of the Exchange Act) selected by us as a replacement Rating Agency for a former Rating Agency.

“Rating Event” means the rating on the New Notes is lowered by each of the Rating Agencies and the New Notes are rated below an Investment Grade Rating by each of the Rating Agencies on any day within the 60-day period (which 60-day period shall be extended so long as the rating of the New Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) after the earlier of (i) the occurrence of a Change of Control and (ii) public notice of the occurrence of a Change of Control or our intention to effect a Change of Control.

“S&P” means S&P Global Ratings, a division of S&P Global Inc.

“Voting Stock” means, with respect to any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date, the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

Covenants Applicable to the New Notes

The New Notes will have the benefit of the following covenants. We have defined below certain capitalized terms used in this section. Capitalized terms used in this section but not otherwise defined in this prospectus shall have the meanings ascribed to such terms in the Indenture.

27

Restriction on Secured Indebtedness

The Indenture provides that as long as we have any New Notes outstanding under the Indenture, we will not, and we will not permit any Restricted Subsidiary (as defined below) to, create, assume, issue, guarantee or incur any Secured Indebtedness (as defined below), unless immediately thereafter the aggregate amount of all Secured Indebtedness (exclusive of certain types of permitted Secured Indebtedness described below), together with the discounted present value of all rentals (not otherwise excluded from the limitation discussed below under “—Restriction on Sales and Leasebacks”) due in respect of Sale and Leaseback Transactions (as defined below), would not exceed 10% of Consolidated Net Tangible Assets (as defined below). For purposes of the calculation, the discounted present value of all rentals does not include rentals to which the covenant discussed below under “—Restriction on Sales and Leasebacks” does not apply.

This restriction does not apply to Secured Indebtedness secured by the following, which we exclude in computing Secured Indebtedness for the purpose of the restriction:

• Liens (as defined below) on property as to which the New Notes are equally and ratably secured with (or, at our option, prior to) such Secured Indebtedness;

• Liens on property, including any Shares (as defined below) or Indebtedness (as defined below), of any entity existing at the time such entity becomes a Restricted Subsidiary or arising thereafter pursuant to contractual commitments entered into prior to and not in contemplation of such entity becoming a Restricted Subsidiary;

• Liens on property, including any Shares or Indebtedness, existing at the time of acquisition of such property by us or a Restricted Subsidiary, or Liens to secure the payment of all or any part of the purchase price of such property created upon the acquisition of such property by us or a Restricted Subsidiary, or Liens to secure any Secured Indebtedness incurred by us or a Restricted Subsidiary prior to, at the time of, or within one year after the later of, the acquisition, the completion of construction (including any improvements, alterations or repairs to existing property) or the commencement of commercial operation of the project of which such property is a part, which Secured Indebtedness is incurred for the purpose of, and the principal amount secured by any such Lien does not exceed the cost of, financing all or any part of the purchase price thereof or construction or improvements, alterations or repairs thereon;

• Liens securing Secured Indebtedness of any Restricted Subsidiary owing to us or to another Restricted Subsidiary;

• Liens on property of an entity existing at the time such entity is merged or consolidated with us or a Restricted Subsidiary or at the time of a sale, lease or other disposition of the properties of an entity as an entirety or substantially as an entirety to us or a Restricted Subsidiary or arising thereafter pursuant to contractual commitments entered into by such entity prior to and not in contemplation of such merger, consolidation, sale, lease or other disposition;

• Liens on our property or the property of a Restricted Subsidiary in favor of governmental authorities, or any trustee or mortgagee acting on behalf, or for the benefit, of any governmental authorities, to secure partial, progress, advance or other payments pursuant to any contract or statute or to secure any Indebtedness incurred for the purpose of financing all or any part of the purchase price or the cost of construction of the property subject to such Liens (including, without limitation, Liens in connection with pollution control, industrial revenue, private activity or similar financing), and any other Liens incurred or assumed in connection with pollution control, industrial revenue, private activity or similar bonds issued by a governmental authority on behalf of us or a Restricted Subsidiary;

• Liens existing on the first date on which a New Note is authenticated by the Trustee under the Indenture;

• Liens on any property which is not a Principal Property (as defined below); and

28

• Any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part of any Secured Indebtedness referred to in the foregoing, provided that the principal amount of the Secured Indebtedness being extended, renewed or replaced shall not be increased.

Restriction on Sales and Leasebacks

The Indenture provides that we will not, and we will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction, unless:

• after giving effect to the transaction, the aggregate amount of all Attributable Debt (as defined below) with respect to all such transactions plus all Secured Indebtedness outstanding to which the restriction described above under “—Restriction on Secured Indebtedness” is applicable, would not exceed 10% of Consolidated Net Tangible Assets; or

• an amount equal to the greater of (i) the amount of the net proceeds to us or such Restricted Subsidiary or (ii) the fair market value of such property, as determined by our board of directors, is applied to retirement of Funded Debt (as defined below) within one year after the consummation of such transaction.

This restriction will not apply to, and there will be excluded in computing Attributable Debt for the purpose of this restriction or the restriction discussed above under “—Restriction on Secured Indebtedness,” Attributable Debt with respect to any Sale and Leaseback Transaction if:

• such Sale and Leaseback Transaction is entered into in connection with pollution control, industrial revenue, private activity or similar financing;

• we or a Restricted Subsidiary applies an amount equal to the net proceeds (after repayment of any Secured Indebtedness secured by a Lien encumbering such Principal Property which Secured Indebtedness existed immediately before such Sale and Leaseback Transaction) of the sale or transfer of the Principal Property leased pursuant to such Sale and Leaseback Transaction to investment (whether for acquisition, improvement, repair, alteration or construction costs) in another Principal Property within one year prior or subsequent to such sale or transfer; or

• such Sale and Leaseback Transaction was entered into by an entity prior to the time (i) that such entity became a Restricted Subsidiary, (ii) that such entity merged or consolidated with us or a Restricted Subsidiary or (iii) of a sale, lease or other disposition of such entity’s properties as an entirety or substantially as an entirety to us or a Restricted Subsidiary, or, in each case, arises thereafter pursuant to contractual commitments entered into by such entity prior to and not in contemplation of such entity becoming a Restricted Subsidiary or such merger, consolidation, sale, lease or other disposition.

Consolidation, Merger and Sale of Assets

Without the consent of the holders of any outstanding New Notes, we may consolidate with or merge into any other corporation, or convey or transfer our properties and assets substantially as an entirety to any Person, as long as:

• the successor is a corporation organized and existing under the laws of the United States of America or any State or the District of Columbia;

• the successor corporation assumes our obligations on the New Notes and under the Indenture;

• immediately after giving effect to such transaction, no event of default, and no event which, after notice, lapse of time or both, would become an event of default, has occurred and is continuing; and

• other conditions described in the Indenture are met.

Accordingly, the holders of the New Notes may not have protection in the event of a highly leveraged transaction, reorganization, restructuring, merger or similar transaction involving us that may adversely affect the

29

holders. The existing protective covenants applicable to the New Notes would continue to apply to us in the event of a leveraged buyout initiated or supported by us, our management or any of our affiliates or their management, but may not prevent such a transaction from taking place.

For purposes of the above covenants, the following terms will be applicable:

“Attributable Debt” means the present value (discounted in accordance with a method of discounting which for financial reporting purposes is consistent with generally accepted accounting principles but at a discount rate of not less than 10% per annum, compounded annually) of the rental payments during the remaining term of any Sale and Leaseback Transaction for which the lessee is obligated (including any period for which such lease has been extended). Such rental payments shall not include amounts payable by the lessee for maintenance and repairs, insurance, taxes, assessments, water rates and similar charges and for contingent rents (such as those based on sales). In case of any Sale and Leaseback Transaction which is terminable by the lessee upon the payment of a penalty, such rental payments shall also include such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated.

“Consolidated Net Tangible Assets” means the aggregate amount of assets after deducting therefrom (i) all current liabilities and (ii) all goodwill, trade names, trademarks, patents, unamortized debt discount and expense and other like intangibles, all as set forth in our most recent consolidated balance sheet.

“Funded Debt” means (i) all indebtedness for money borrowed having a maturity of more than 12 months from the date as of which the amount thereof is to be determined or having a maturity of less than 12 months from such date but by its terms being renewable or extendible beyond 12 months from such date at the option of the borrower and (ii) any indebtedness for borrowed money which may be payable from the proceeds under or pursuant to an agreement to provide borrowings with a maturity of more than 12 months from the date as of which the amount thereof is to be determined.

“Indebtedness” means, as to any corporation or other Person, all indebtedness for money borrowed which is created, assumed, incurred or guaranteed in any manner by such corporation or other Person or for which such corporation or other Person is otherwise responsible or liable.

“Lien” means any mortgage, pledge, security interest, lien or other similar encumbrance.

“Principal Property” means (i) any Manufacturing Plant (as defined below) located in the United States, or Manufacturing Equipment (as defined below) located in any such Manufacturing Plant (together with the land on which such plant is erected and fixtures comprising a part thereof), owned or leased on the first date on which a New Note is authenticated by the Trustee or thereafter acquired or leased by us or any Restricted Subsidiary, and (ii) any Shares issued by, or any interest of ours or any Subsidiary in, any Restricted Subsidiary, other than (1) any property or Shares or interests the book value of which is less than 1% of Consolidated Net Tangible Assets or (2) any property or Shares or interests which our board of directors determines is not of material importance to the total business conducted, or assets owned, by us and our Subsidiaries, as an entirety, or (3) any portion of any property which our board of directors determines not to be of material importance to the use or operation of such property. “Manufacturing Plant” does not include any plant owned or leased jointly or in common with one or more Persons other than us and our Restricted Subsidiaries in which the aggregate direct or indirect interest of ours and our Restricted Subsidiaries does not exceed 50%. “Manufacturing Equipment” means manufacturing equipment in such Manufacturing Plants used directly in the production of our or any Restricted Subsidiary’s products and does not include office equipment, computer equipment, rolling stock and other equipment not directly used in the production of our or any Restricted Subsidiary’s products.

“Restricted Subsidiary” means any Subsidiary substantially all the property of which is located within the United States, other than a Subsidiary primarily engaged in investing in and/or financing our or any Subsidiary’s or affiliate’s operations outside the United States.

“Sale and Leaseback Transaction” means any arrangement with any Person providing for the leasing by us or any Restricted Subsidiary of any Principal Property of ours or any Restricted Subsidiary, whether such Principal Property is now owned or hereafter acquired (except for leases for a term of not more than three years and except for leases between us and a Restricted Subsidiary or between Restricted Subsidiaries and except for leases of property executed prior to, at the time of, or within one year after the later of, the acquisition, the completion of construction, including any improvements or alterations on real property, or the commencement of commercial operation of such property), which Principal Property has been or is to be sold or transferred by us or such Restricted Subsidiary to such Person.

“Secured Indebtedness” means Indebtedness secured by any Lien upon property (including Shares or Indebtedness issued by or other ownership interests in any Restricted Subsidiary) owned by us or any Restricted Subsidiary.

“Shares” means, as to any corporation, all the issued and outstanding equity shares (except for directors’ qualifying shares) of such corporation.

Events of Default

The following are “events of default” with respect to the New Notes:

• default in the payment of any interest installment with respect to the New Notes, as and when the same shall become due and payable, and continuance of such default for a period of 15 days after receipt by us of written notice of the default from any holder of the New Notes or the Trustee;

• default in the payment of the principal of, or premium, if any, on, the New Notes, as and when the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise;

• default in the making of any payment for a sinking, purchase or analogous fund provided for in respect of the New Notes, as and when the same shall become due and payable;

• failure by us to observe or perform any other covenant or agreement in respect of the New Notes, or in the Indenture with respect to the New Notes, for a period of 90 days after the Trustee gives us written notice, or holders of at least 25% in aggregate principal amount of the outstanding New Notes give us and the Trustee written notice of default; and

• certain events of bankruptcy, insolvency and reorganization as more fully described in the Indenture.

The Trustee shall not be deemed to have knowledge or notice of any event of default unless (i) a responsible officer of the Trustee has actual knowledge thereof or has received written notice of such or (ii) the holders of at least 25% in aggregate principal amount of the outstanding New Notes as to which there exists an event of default give written notice of such event of default to the Trustee.

Modification of the Indenture

The Indenture provides that we and the Trustee may, without the consent of any holders of New Notes, enter into supplemental indentures for the purposes, among other things, of:

• adding further events of default or other covenants, restrictions or conditions for the benefit of the holders of the New Notes;

• establishing the form or terms of any series of debt securities; or

• clarifying or curing ambiguities or inconsistencies in the Indenture or making other provisions in regard to matters or questions arising under the Indenture or any supplemental indenture or debt securities of a series, which will not adversely affect the interests of the holders of the New Notes in any material respect.

31

We and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the New Notes at the time outstanding, may execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or the New Notes or of modifying in any manner the rights of the holders of New Notes, except that no such supplemental indenture may, without the consent of the holders of all the New Notes then outstanding:

• change the fixed maturity (which term for these purposes does not include payments due pursuant to any sinking, purchase or analogous fund) of the New Notes, reduce the principal amount thereof, reduce the rate or extend the time of payment of interest thereon, reduce any premium payable upon the redemption thereof, or impair the right to institute suit for the enforcement of any such payment on or after the maturity thereof (or, in the case of redemption on or after the redemption date, without the consent of the holders of the New Notes so affected); or

• reduce the percentage of the New Notes required to approve any such supplemental indenture.

The Effect of Our Corporate Structure on Our Payment of the New Notes

The New Notes are the obligations of Nucor exclusively. Because our operations are currently conducted in significant part through subsidiaries, the cash flow and our consequent ability to service our debt, including the New Notes, are dependent, in part, upon the earnings of our subsidiaries and the distribution of those earnings to us or upon loans or other payments of funds by those subsidiaries to us. Our subsidiaries are separate and distinct legal entities. They have no obligation, contingent or otherwise, to pay any amounts due on the New Notes or to make any funds available for our payment of any amounts due on the New Notes, whether by dividends, loans or other payments. In addition, our subsidiaries’ payments of dividends and making of loans and advances to us may be subject to statutory or contractual restrictions and are contingent upon the earnings of those subsidiaries and various business considerations.

The New Notes will be structurally subordinated to all indebtedness and other liabilities, including current liabilities and commitments under leases, if any, of our subsidiaries. Any right of ours to receive assets of any of our subsidiaries upon liquidation or reorganization of the subsidiary (and the consequent right of the holders of the New Notes to participate in those assets) will be effectively subordinated to the claims of that subsidiary’s creditors (including trade creditors), except to the extent that we are recognized as a creditor of the subsidiary, in which case our claims would still be subordinated to any security interests in the subsidiary’s assets and any of the subsidiary’s indebtedness senior to that which we hold.

No Restriction on Sale or Issuance of Stock of Subsidiaries

The Indenture contains no covenant that we will not sell, transfer or otherwise dispose of any shares of, securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, voting stock of any of our subsidiaries. It also does not prohibit any subsidiary of Nucor from issuing any shares of, securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, such subsidiary’s voting stock.

No Personal Liability of Incorporators, Stockholders, Officers, Directors or Employees

No recourse for the payment of the principal of, premium, if any, or interest, if any, on the New Notes, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any of our obligations, covenants or agreements in the Indenture or in a supplemental indenture or in the New Notes, or because of the creation of any indebtedness represented thereby, will be had against any of our incorporators, stockholders, officers, directors or employees or of any successor person thereof. Each holder, by accepting the New Notes issued under the Indenture, waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the New Notes. This waiver may not be effective to waive liabilities under the federal securities laws.

32

Reports to Holders and SEC Reports

We will, so long as any New Notes are outstanding, file with the Trustee and the SEC, and transmit to holders of the New Notes, the information, documents and other reports, and such summaries thereof, as may be required pursuant to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), at the times and in the manner provided in the Trust Indenture Act; provided, that any such information, documents or other reports required to be filed with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act will be filed with the Trustee within 30 days after the information, documents or other reports are required to be filed with the SEC. All such required information, documents and other reports will be deemed filed with the Trustee and transmitted to holders of the New Notes at the time such information, documents or other reports are publicly filed with the SEC via the SEC’s EDGAR filing system (or any successor system); provided, however, that the Trustee will have no responsibility to determine whether or not such filing has taken place.

Book-Entry System, Delivery and Form

The certificates representing the New Notes will be issued in the form of one or more fully registered global notes (each, a “Global Note”) and will be deposited with, or on behalf of, DTC and registered in the name of Cede & Co., as the nominee of DTC. Except in limited circumstances, the New Notes will not be issuable in definitive form. Unless and until they are exchanged, in whole or in part, for the individual New Notes represented thereby, any interests in a Global Note may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any nominee of DTC to a successor depositary or any nominee of such successor.

DTC has advised us that DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly. The DTC rules applicable to Direct Participants are on file with the SEC.

Holding through Euroclear and Clearstream

Investors may hold interests in a Global Note through Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), or Clearstream Banking, S.A. (“Clearstream”), in each case, as a participant in DTC. Euroclear and Clearstream will hold interests, in each case, on behalf of their participants through customers’ securities accounts in the names of Euroclear and Clearstream on the books of their respective depositary, which in turn will hold such interests in customers’ securities in the depositaries’ names on DTC’s books.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the New Notes made through Euroclear or Clearstream must comply with the rules and procedures of those systems. Those systems could change their rules and procedures at any time. We and the Trustee have no control over those systems or their participants, and we and the Trustee take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on the one hand, and other participants in DTC, on the other hand, would also be subject to DTC’s rules and procedures.

33

Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, U.S. investors who hold interests in the New Notes through those systems and wish on a particular day to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, may find that the transaction will not be effected until the next business day in Brussels or Luxembourg, as applicable. Thus, if investors wish to exercise rights that expire on a particular day, they may need to act before the expiration date. In addition, if investors hold their interests through both DTC and Euroclear or Clearstream, they may need to make special arrangements to finance any purchases or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than transactions within one clearing system.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of the New Notes among participants of DTC, Euroclear and Clearstream, they are under no obligation or responsibility to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

Same-Day Funds Payment

All payments of principal and interest in respect of New Notes in book-entry form will be made by us in immediately available funds to the accounts specified by DTC.

The New Notes will trade in DTC’s Same-Day Funds Settlement System until maturity or until the New Notes are issued in certificated form, and secondary market trading activity in the New Notes will therefore be required by DTC to settle in immediately available funds.

The Trustee

U.S. Bank National Association is the trustee under the Indenture. All payments of principal of, premium, if any, and interest on, and all registration, transfer, exchange, authentication and delivery of, the New Notes will be effected by the Trustee at the corporate trust office of the Trustee in Charlotte, North Carolina.

U.S. Bank National Association is a lender under our unsecured revolving credit facility. Consequently, U.S. Bank National Association could be faced with potential conflicts of interest and conflicting obligations in the event of a default under, or with regard to other circumstances relating to, any or all of this indebtedness.

The Indenture and provisions of the Trust Indenture Act contain limitations on the rights of the Trustee, should it become a creditor of ours, to obtain payment of claims in certain cases or to liquidate certain property received by it in respect of any such claim as security or otherwise. The Trustee is permitted to engage in other transactions with us or any of our affiliates. If the Trustee acquires any conflicting interest within the meaning of the Trust Indenture Act and the New Notes are in default, it must eliminate that conflict, resign or, if applicable, apply to the SEC to continue.

The Trustee or its affiliates may in the future serve as trustee under various of our debt instruments and have served and may in the future serve as an agent and lender under our credit facilities.

Governing Law

The Indenture and the New Notes shall be governed by and construed in accordance with the laws of the State of New York.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of certain material U.S. federal income tax consequences of the exchange offer to holders of Existing Notes, but is not a complete analysis of all potential tax effects. The summary below is based upon the Internal Revenue Code of 1986, as amended (the “Code”), regulations of the Treasury Department, administrative rulings and pronouncements of the Internal Revenue Service and judicial decisions, all of which are subject to change, possibly with retroactive effect. This summary does not address all of the U.S. federal income tax consequences that may be applicable to particular holders, including dealers in securities, financial institutions, insurance companies and tax-exempt organizations. In addition, this summary does not consider the effect of any foreign, state, local, gift, estate or other tax laws that may be applicable to a particular holder. This summary applies only to a holder that acquired Existing Notes at original issue for cash and holds such Existing Notes as a capital asset within the meaning of Section 1221 of the Code.

An exchange of Existing Notes for New Notes pursuant to the exchange offer will not be treated as a taxable exchange or other taxable event for U.S. federal income tax purposes. Accordingly, there will be no U.S. federal income tax consequences to holders who exchange their Existing Notes for New Notes in connection with the exchange offer and any such holder will have the same adjusted tax basis and holding period in the New Notes as it had in the Existing Notes immediately before the exchange.

The foregoing discussion of certain material U.S. federal income tax consequences does not consider the facts and circumstances of any particular holder’s situation or status. Accordingly, each holder of Existing Notes considering the exchange offer should consult its own tax advisor regarding the tax consequences of the exchange offer to it, including those under state, foreign and other tax laws.

35

PLAN OF DISTRIBUTION

Each broker-dealer that receives New Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Notes received in exchange for Existing Notes where such Existing Notes were acquired as a result of market-making activities or other trading activities. We have agreed that, for a period of 180 days after the last Exchange Date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until                 , 2021, all dealers effecting transactions in the New Notes may be required to deliver a prospectus.

We will not receive any proceeds from any sale of New Notes by broker-dealers. New Notes received by broker-dealers for their own accounts pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the New Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from a broker-dealer and/or the purchasers of any such New Notes. Any broker-dealer that resells New Notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such New Notes may be deemed to be an “underwriter” within the meaning of the Securities Act, and any profit on any such resale of New Notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 180 days after the last Exchange Date, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all reasonable expenses incident to the exchange offer (including the reasonable expenses of one counsel for the holders of the New Notes) other than underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of New Notes by any holder. In addition, we have agreed to indemnify the holders of the New Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Set forth below is a description of certain provisions of the registrant’s Restated Certificate of Incorporation and the General Corporation Law of the State of Delaware (the “DGCL”), as such provisions relate to the indemnification of the directors and officers of the registrant. This description is intended only as a summary and is subject to, and is qualified in its entirety by reference to, the registrant’s Restated Certificate of Incorporation and the DGCL.

Section 145 of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful, except that, in the case of an action by or in the right of the corporation, no indemnification may be made in respect of any claim, issue or matter as to which such person is adjudged to be liable to the corporation, unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court deems proper. The registrant’s Restated Certificate of Incorporation provides that the registrant will indemnify and advance expenses to its directors and officers to the fullest extent permitted by law.

Section 102(b)(7) of the DGCL permits a corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) for unlawful payment of dividends or purchase or redemption of shares; or (iv) for any transaction from which the director derived an improper personal benefit. Neither the registrant’s Restated Certificate of Incorporation nor its Bylaws contain such a provision.

Section 145 of the DGCL also permits a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation. The registrant maintains directors’ and officers’ liability insurance for its directors and officers.

Item 22. Undertakings

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

II-3

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Re: Nucor Corporation – Registration Statement on Form S-4 under the Securities Act of 1933, as amended

Ladies and Gentlemen:

We have acted as counsel to Nucor Corporation, a Delaware corporation (the “Company”), in connection with the registration, pursuant to a registration statement on Form S-4 (the “Registration Statement”), filed by the Company with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the proposed offer by the Company to exchange an aggregate principal amount of up to $439,312,000 of the Company’s outstanding 2.979% Notes due 2055 (the “Existing Notes”) for a like principal amount of the Company’s registered 2.979% Notes due 2055 (the “New Notes”). The Existing Notes were issued, and the New Notes will be issued, under an indenture, dated as of August 19, 2014, as amended or supplemented by a first supplemental indenture, dated as of April 26, 2018, a second supplemental indenture, dated as of May 22, 2020, and a third supplemental indenture, dated as of December 7, 2020, in each case, between the Company and U.S. Bank National Association, as trustee (the “Trustee”) (together, the “Indenture”).

In connection with this opinion letter, we have (i) investigated such questions of law; (ii) examined originals or copies, certified or otherwise identified to our satisfaction, of such agreements, instruments, documents and records of the Company (including, without limitation, the Indenture, the Restated Certificate of Incorporation and the Bylaws of the Company, as amended and restated through the date hereof) and certificates of public officials; and (iii) received such information from officers and representatives of the Company and others, in each case, as we have deemed necessary or appropriate for the purposes of the opinions hereafter expressed. In all such investigations and examinations and for purposes of rendering these opinions, we have assumed the legal capacity and competency of all natural persons executing documents and certificates submitted to us, the genuineness of all signatures, the authenticity of original and certified documents submitted to us, the conformity to original or certified documents of all copies submitted to us as conformed or reproduction copies and that any certificate or document upon which we have relied and which was given or dated earlier than the date of this opinion letter continues to remain accurate, insofar as relevant to the opinions contained herein, from such earlier date through and including the date hereof. As to various questions of fact relevant to the opinions expressed herein, we have relied upon, and assumed the accuracy and completeness of, statements contained in the Indenture and any other documents executed, delivered or entered into in connection with the Registration Statement and certificates and oral or written statements and other information of or from public officials and officers and representatives of the Company and others and assumed compliance on the part of all parties to the Indenture with their covenants and agreements contained therein. With your permission, all assumptions and statements of reliance herein have been made without any independent investigation or verification on our part, except to the extent otherwise expressly stated, and we express no opinion with respect to the accuracy of such assumptions or items relied upon.

Nucor Corporation

In connection with this opinion letter, we have assumed that (i) the Registration Statement and any amendments thereto (including post-effective amendments) have become effective, no stop order suspending the effectiveness of the Registration Statement or preventing the use of any prospectus or prospectus supplement has been or will be issued and no proceedings for that purpose have been or will be instituted or threatened by the SEC; (ii) the Indenture has been and will remain qualified under the Trust Indenture Act of 1939, as amended; (iii) the New Notes will be issued and delivered in compliance with applicable federal and state securities laws in exchange for the Existing Notes and in the manner stated in the Registration Statement; (iv) the New Notes will be duly authorized, executed and delivered by the parties thereto in substantially the form reviewed by us and in accordance with the provisions of the Indenture; (v) the New Notes will be duly authenticated by the Trustee in the manner provided in the Indenture; (vi) each person who signed the Indenture had, and each person who will sign the New Notes will have, the legal capacity and authority to do so and the Indenture has been duly authorized, executed and delivered by the parties thereto; and (vii) the Indenture constitutes the valid and legally binding obligation of the Trustee.

Based upon the foregoing and subject to the limitations, qualifications and assumptions set forth herein, we are of the opinion that the New Notes, when issued by the Company, will be validly authorized and issued and will constitute binding obligations of the Company, enforceable against the Company in accordance with their terms.

The opinions expressed herein are limited to matters governed by the laws of the States of North Carolina and New York and the General Corporation Law of the State of Delaware other than any case law thereunder, each as currently in effect, and no opinion is expressed with respect to such laws as subsequently amended, or any other laws, or any effect that such amended or other laws may have on the opinions expressed herein. We do not find it necessary for purposes of this opinion letter, and accordingly we do not purport to cover herein, the application of the securities or “Blue Sky” laws of the various states to the offer and sale of the New Notes.

We express no opinion as to:

(i) the legality, validity, binding effect or enforceability of any provision of the Indenture or the New Notes relating to indemnification or contribution or exculpation;

(ii) the legality, validity, binding effect or enforceability of any provision of the Indenture or the New Notes intended to act as a savings clause;

(iii) any right of set-off; or

(iv) the legality, validity, binding effect or enforceability of any provision of the Indenture or the New Notes:

(A) relating to forum selection or submission to jurisdiction (including, without limitation, any waiver of any objection to venue in any court or of any objection that a court is an inconvenient forum) to the extent that the legality, validity, binding effect or enforceability of any such provision is to be determined by any court other than a court of the State of New York;

(B) specifying that provisions thereof may be waived only in writing, to the extent that an oral agreement or an implied agreement by trade practice or course of conduct has been created that modifies any provision of such agreement or instrument; or

(C) purporting to give any person or entity the power to accelerate obligations without any notice to the obligor.

The opinions expressed herein are subject to the following:

(i) bankruptcy, insolvency, reorganization, moratorium (or related judicial doctrines) and other laws now or hereafter in effect affecting creditors’ rights and remedies generally;

(ii) general principles of equity (including, without limitation, standards of materiality, good faith, fair dealing and reasonableness, equitable defenses and limits as to the availability of equitable remedies), whether such principles are considered in a proceeding in equity or at law;

(iii) the application of any applicable fraudulent conveyance, fraudulent transfer, fraudulent obligation, or preferential transfer law or any law governing the distribution of assets of any person now or hereafter in effect affecting creditors’ rights and remedies generally; and

(iv) the qualification that certain provisions of the Indenture or the New Notes or any other instruments defining the rights of holders thereof may be unenforceable in whole or in part, but the inclusion of such provisions does not affect the validity as against the Company of the Indenture or the New Notes or any other instruments defining the rights of holders thereof as a whole, and the Indenture or the New Notes or any other instruments defining the rights of holders thereof and the laws of the State of New York contain adequate provisions for enforcing payment of the obligations governed thereby, subject to the other qualifications contained in this opinion letter.

The opinions expressed herein are given as of the date hereof, and we undertake no obligation to supplement this opinion letter if any applicable laws change after the date hereof or if we become aware of any facts that might change the opinions expressed herein or for any other reason. No opinion may be inferred or implied beyond the matters expressly contained herein.

We hereby consent to the filing of this opinion letter as an exhibit to the Registration Statement in accordance with the requirements of Item 601(b)(5)(i) of Regulation S-K under the Securities Act and to the use of our name in the prospectus forming a part of the Registration Statement under the caption “Legal Matters.” In giving such consent, we do not hereby admit that we are within the category of such persons whose consent is required under Section 7 of the Securities Act or the rules and regulations promulgated thereunder by the SEC.

Very truly yours,

The instructions contained in this Letter of Transmittal should be read carefully before it is completed. This Letter of Transmittal need not be completed by holders tendering Existing Notes through The Depository Trust Company’s (“DTC”) Automated Tender Offer Program (“ATOP”). By tendering Existing Notes and accepting the New Notes (as defined below) in the Exchange Offer and by delivering an “agent’s message” through ATOP, holders will be deemed to have made the acknowledgements, representations and agreements set forth in the Prospectus (as defined below) and in this Letter of Transmittal. This Letter of Transmittal may be used to participate in the Exchange Offer if Existing Notes are to be tendered by effecting a book-entry transfer into the Exchange Agent’s account at DTC and instructions are not being transmitted through ATOP.

The undersigned acknowledges receipt of the Prospectus, dated                 , 2021 (the “Prospectus”), of Nucor Corporation (“Nucor,” the “Company,” “we,” “us” or “our”) and this Letter of Transmittal (this “Letter of Transmittal”), which together describe Nucor’s offer (the “Exchange Offer”) to exchange up to $439,312,000 aggregate principal amount of its 2.979% Notes due 2055 (“New Notes”) that have been registered under the

Securities Act of 1933, as amended (the “Securities Act”), for a like principal amount of its 2.979% Notes due 2055 (CUSIP Nos. 670346 AT2 and U66980 AC4 / ISIN Nos. US670346AT26 and USU66980AC46) (“Existing Notes”) that have not been registered under the Securities Act, upon the terms and subject to the conditions set forth in the Prospectus and in this Letter of Transmittal. Nucor is relying on the position of the staff (the “Staff”) of the United States Securities and Exchange Commission (the “SEC”) enunciated in Exxon Capital Holdings Corporation, SEC No-Action Letter (available May 13, 1988), and Morgan Stanley & Co. Incorporated, SEC No-Action Letter (available June 5, 1991), as interpreted in Shearman & Sterling, SEC No-Action Letter (available July 2, 1993), to consummate the Exchange Offer. Capitalized terms used but not defined herein have the meanings assigned to them in the Prospectus.

We are offering to exchange all of our outstanding Existing Notes for a like principal amount of New Notes. As set forth in the Prospectus, the terms of the New Notes are substantially identical in all material respects to the terms of the Existing Notes, except that the New Notes are registered under the Securities Act, and the transfer restrictions, registration rights and payment of additional interest in case of non-registration applicable to the Existing Notes do not apply to the New Notes. Holders of the New Notes will not be, and upon consummation of the Exchange Offer, holders of the Existing Notes will no longer be, entitled to (i) the right to receive payments of additional interest, if any, or (ii) certain other rights intended for holders of Existing Notes, in either case, under the registration rights agreement, dated as of December 7, 2020, among the Company, BofA Securities, Inc., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC, as lead dealer managers, and Deutsche Bank Securities Inc., RBC Capital Markets, LLC, U.S. Bancorp Investments, Inc., Siebert Williams Shank & Co., LLC, Fifth Third Securities, Inc., PNC Capital Markets LLC and MUFG Securities Americas Inc., as co-dealer managers (the “Registration Rights Agreement”), except in limited circumstances described in the Prospectus. The Exchange Offer shall be deemed consummated upon the occurrence of the delivery by the Company to the Trustee (as defined below) of New Notes in the same aggregate principal amount as the aggregate principal amount of Existing Notes that are tendered by holders thereof pursuant to the Exchange Offer.

The Existing Notes are governed by, and were issued pursuant to, the terms of an indenture, dated as of August 19, 2014, as amended or supplemented by a first supplemental indenture, dated as of April 26, 2018, a second supplemental indenture, dated as of May 22, 2020, and a third supplemental indenture, dated as of December 7, 2020, in each case, between the Company and U.S. Bank National Association, as trustee (the “Trustee”) (together, the “Indenture”). The New Notes will be governed by the terms of the Indenture.

Interest on the New Notes will accrue from the date interest on the Existing Notes was most recently paid, at the rate of 2.979% per annum. Interest on the New Notes will be payable semi-annually in arrears on June 15 and December 15 of each year to the holders of record on the immediately preceding June 1 and December 1, respectively.

The Company reserves the right, in its sole discretion, to extend the Exchange Offer or to amend or terminate the Exchange Offer if any of the conditions described under the heading “The Exchange Offer—Conditions” in the Prospectus have not been satisfied or waived by giving notice to the Exchange Agent of the extension, amendment or termination. Further, the Company reserves the right, in its sole discretion, to amend the terms of the Exchange Offer in any manner. The Company will, as promptly as practicable, give written notice of any extension, amendment or termination of the Exchange Offer to the holders of the Existing Notes. The minimum period during which the Exchange Offer will remain open following material changes in the terms of the Exchange Offer or in the information concerning the Exchange Offer will depend upon the facts and circumstances of such changes, including the relative materiality of the changes. If the Company determines to extend the Exchange Offer, it will notify the Exchange Agent of any extension and give each registered holder notice of the extension by means of a press release or other public announcement, which notice shall include the approximate number of Existing Notes tendered to date, before 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

All of the Existing Notes are held in book-entry form through the facilities of DTC. New Notes will be delivered in book-entry form through DTC and only to the DTC account of the undersigned or the undersigned’s custodian, as specified in the table below entitled “Method of Delivery.”

Holders of Existing Notes tendering by book-entry transfer to the Exchange Agent’s account at DTC may execute tenders through ATOP, for which the Exchange Offer is eligible. Financial institutions that are DTC participants may execute tenders through ATOP by transmitting acceptance of

2

the Exchange Offer to DTC at or prior to the Expiration Date. DTC will verify acceptance of the Exchange Offer, execute a book-entry transfer of the tendered Existing Notes into the account of the Exchange Agent at DTC and send to the Exchange Agent a “book-entry confirmation,” which shall include an agent’s message. The term “agent’s message” means a message, transmitted by DTC and received by the Exchange Agent and forming part of the confirmation of a book-entry transfer, which states the aggregate principal amount of Existing Notes that have been tendered by such participant pursuant to the Exchange Offer, that DTC has received an express acknowledgment from a participant in DTC tendering Existing Notes, that such participant has received this Letter of Transmittal and agrees to be bound by the terms of this Letter of Transmittal, and that Nucor may enforce such agreement against the participant. Delivery of an agent’s message will also constitute an acknowledgment from the tendering DTC participant that the representations, warranties and agreements set forth in this Letter of Transmittal are true and correct. Accordingly, holders who tender their Existing Notes through DTC’s ATOP procedures shall be bound by, but need not complete, this Letter of Transmittal.

To effect a valid tender of Existing Notes through the completion, execution and delivery of this Letter of Transmittal, the undersigned must complete the tables below entitled “Description of Existing Notes Tendered” and “Method of Delivery” and sign this Letter of Transmittal where indicated. Existing Notes can be tendered only in principal amounts equal to the minimum authorized denomination of $2,000 and integral multiples of $1,000 in excess thereof, as set forth under the heading “The Exchange Offer—Minimum Authorized Denominations” in the Prospectus.

Any holder that is a bank, broker or other custodial entity holding Existing Notes on behalf of more than one beneficial owner may submit to the Exchange Agent a list of the aggregate principal amount of Existing Notes owned by each such beneficial owner, and the Exchange Agent, in determining the aggregate principal amount of New Notes to be issued to such holder, will treat each such beneficial owner as a separate holder. A holder whose Existing Notes are registered in the name of a bank, broker, dealer, custodian or other nominee should contact its nominee a sufficient time ahead of the Expiration Date to permit its nominee to participate in the Exchange Offer on its behalf.

If the undersigned holder of Existing Notes who will receive New Notes is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend to engage in, a distribution of the New Notes. If the undersigned holder of Existing Notes who will receive New Notes is a broker-dealer (a “Participating Broker-Dealer”), the undersigned represents that the Existing Notes to be exchanged for the New Notes were acquired for its own account as a result of market-making activities or other trading activities, and the undersigned acknowledges that it will deliver, or, to the extent permitted by applicable law, make available to purchasers, a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes received in respect of such Existing Notes pursuant to the Exchange Offer; however, by so acknowledging and by delivering or making available such a prospectus, the undersigned will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

Nucor has not provided guaranteed delivery procedures in connection with the Exchange Offer.

The Exchange Offer is described in the Prospectus and in this Letter of Transmittal. All terms and conditions contained in, or otherwise referred to in, the Prospectus are deemed to be incorporated in, and form a part of, this Letter of Transmittal. Therefore, you are urged to carefully read the Prospectus and the items referred to therein. The terms and conditions contained in the Prospectus, together with the terms and conditions governing this Letter of Transmittal and the instructions herein, are collectively referred to herein as the “terms and conditions.”

PLEASE READ THIS ENTIRE LETTER OF TRANSMITTAL CAREFULLY BEFORE COMPLETING ANY BOX BELOW. IN ORDER TO VALIDLY TENDER EXISTING NOTES FOR EXCHANGE, HOLDERS OF EXISTING NOTES MUST COMPLETE, EXECUTE AND DELIVER THIS LETTER OF TRANSMITTAL OR A PROPERLY TRANSMITTED AGENT’S MESSAGE.

PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

Ladies and Gentlemen:

The undersigned hereby acknowledges and agrees that:

(1) any New Notes to be received by the holder of Existing Notes in the Exchange Offer will be acquired in the ordinary course of the holder’s business;

(2) the holder is not participating, and has no arrangement or understanding with any person to participate, in a distribution (within the meaning of the Securities Act) of the New Notes in violation of the provisions of the Securities Act;

(3) the holder is not an “affiliate” (as defined in Rule 405 under the Securities Act) of Nucor; and

(4) if the holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, a distribution of the New Notes.

In addition, in connection with any resale of New Notes, any Participating Broker-Dealer who acquired the Existing Notes for its own account as a result of market-making activities or other trading activities must deliver, or, to the extent permitted by applicable law, make available to purchasers, a prospectus meeting the requirements of the Securities Act. The SEC has taken the position that Participating Broker-Dealers may fulfill their prospectus delivery requirements with respect to the New Notes (other than a resale of an unsold allotment from the original sale of the Existing Notes) by using the Prospectus contained in the registration statement of which the Prospectus forms a part that is declared effective by the SEC. We will allow Participating Broker-Dealers and other persons, if any, subject to similar prospectus delivery requirements to use the Prospectus in connection with the resale of such New Notes, subject to limitations set forth in the Registration Rights Agreement.

Any holder of Existing Notes using the Exchange Offer to participate in a distribution of the New Notes (i) cannot rely on the position of the Staff of the SEC enunciated in its interpretive letters with respect to Exxon Capital Holdings Corporation, SEC No-Action Letter (available May 13, 1988), and Morgan Stanley & Co. Incorporated, SEC No-Action Letter (available June 5, 1991), as interpreted in Shearman & Sterling, SEC No-Action Letter (available July 2, 1993), and similar interpretive letters, and (ii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction.

We will be deemed to have accepted validly tendered Existing Notes for exchange when, as and if we have given notice of our acceptance to the Exchange Agent. The undersigned understands that, subject to the terms and conditions, Existing Notes validly tendered and not validly withdrawn and accepted in accordance with the terms and conditions will be exchanged for New Notes as provided under the terms and conditions of the Exchange Offer described in the Prospectus. The undersigned understands that any Existing Notes tendered pursuant to the Exchange Offer may be withdrawn, subject to the procedures set forth in the Prospectus and herein, at any time at or prior to the Withdrawal Deadline. The Exchange Agent will act as agent for the tendering holders for the purpose of receiving the New Notes from us.

If any Existing Notes are not accepted for exchange for any reason, or if Existing Notes are validly withdrawn, such Existing Notes will be returned, without expense, to the undersigned at its participant account at DTC shown above in the box entitled “Description of Existing Notes Tendered” or such other account as designated herein promptly after the expiration or termination of the Exchange Offer.

5

Following the later of the Withdrawal Deadline or the date upon which Existing Notes are tendered hereby, and subject to and effective upon Nucor’s acceptance for exchange of the principal amount of the Existing Notes tendered hereby, upon the terms and conditions set forth in the Prospectus and in this Letter of Transmittal, the undersigned hereby:

(1) tenders to Nucor the Existing Notes indicated above in the box entitled “Description of Existing Notes Tendered,” and in doing so irrevocably sells, assigns and transfers to or upon the order of Nucor or its nominee all right, title and interest in and to, and any and all claims in respect of or arising or having arisen as a result of the undersigned’s status as a holder of, all Existing Notes tendered hereby, such that thereafter the undersigned shall have no contractual or other rights or claims in law or equity against Nucor or any fiduciary, trustee or other person connected with the Existing Notes arising under, from or in connection with such Existing Notes or the Indenture;

(2) waives any and all rights with respect to the Existing Notes tendered hereby, including, without limitation, any existing or past defaults and their consequences in respect of such Existing Notes and the Indenture;

(3) releases and discharges Nucor and its affiliates and the Trustee with respect to the Indenture from any and all claims that the undersigned may have, now or in the future, arising out of or related to the Existing Notes tendered hereby or the Indenture, including, without limitation, any claims that the undersigned is entitled to receive additional principal or interest payments with respect to the Existing Notes tendered hereby, other than accrued and unpaid interest on the Existing Notes or as otherwise expressly provided in the Prospectus and in this Letter of Transmittal, or to participate in any repurchase, redemption or defeasance of the Existing Notes tendered hereby; and

(4) irrevocably constitutes and appoints the Exchange Agent as its true and lawful agent and attorney-in-fact (with full knowledge that the Exchange Agent also acts as Nucor’s agent with respect to the Existing Notes) with respect to any tendered Existing Notes, with full power of substitution and resubstitution, and irrevocably instructs the Exchange Agent (as its agent and attorney-in-fact) to complete and execute all or any forms of transfer and other documents at the discretion of the Exchange Agent (as its agent and attorney-in-fact) in relation to the Existing Notes tendered in favor of Nucor or any other person or persons as Nucor may direct and to deliver those forms of transfer and other documents in the Exchange Agent’s discretion (as its agent and attorney-in-fact) and the certificates and other documents of title relating to the registration of Existing Notes and to execute all other documents and to do all other acts and things as may be in the opinion of the Exchange Agent (as its agent and attorney-in-fact) necessary or expedient for the purpose of, or in connection with, the acceptance of such Exchange Offer, and to vest in Nucor or its nominees those Existing Notes. The power of attorney granted above shall be deemed irrevocable and coupled with an interest.

The undersigned understands that tenders of Existing Notes pursuant to the procedures described in the Prospectus and the instructions in this Letter of Transmittal and acceptance of such Existing Notes by Nucor will, following such acceptance, constitute a binding agreement between the undersigned and Nucor upon the terms and subject to the conditions of the Exchange Offer.

All authority conferred or agreed to be conferred by this Letter of Transmittal shall not be affected by, and shall survive, the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, executors, administrators, trustees in bankruptcy, personal and legal representatives, successors and assigns of the undersigned.

The undersigned hereby represents, warrants and agrees that:

(1) it has received the Prospectus and this Letter of Transmittal;

(2) it is the beneficial owner of, or a duly authorized representative of one or more beneficial owners of, the Existing Notes tendered hereby, and it has full power and authority to execute or agree to be bound by this Letter of Transmittal and to tender, exchange, sell, assign and transfer the Existing Notes tendered and to acquire the New Notes issuable upon the exchange of such tendered Existing Notes;

(3) as of the date of delivery of this Letter of Transmittal to the Exchange Agent or an agent’s message through ATOP, as applicable, the Existing Notes being tendered hereby were owned free and clear of any liens, charges, claims, encumbrances, interests and restrictions of any kind, and Nucor will acquire good, indefeasible and unencumbered title to those Existing Notes, free and clear of all liens, charges, claims, encumbrances, interests and restrictions of any kind, when the same are accepted for exchange by Nucor;

6

(4) it will, upon request, execute and deliver any additional documents reasonably deemed by the Exchange Agent or Nucor to be necessary or desirable to complete the sale, assignment and transfer of the tendered Existing Notes on the account books maintained by the book-entry transfer facility;

(5) acceptance of any and all validly tendered Existing Notes by Nucor and the issuance of New Notes in exchange therefor shall constitute performance in full by Nucor of its obligations under the Registration Rights Agreement and that Nucor shall have no further obligations or liabilities thereunder;

(6) any New Notes to be received by it in the Exchange Offer will be acquired in the ordinary course of its business;

(7) it is not participating, and has no arrangement or understanding with any person to participate, in a distribution (within the meaning of the Securities Act) of the New Notes in violation of the provisions of the Securities Act;

(8) it is not an “affiliate” (as defined in Rule 405 under the Securities Act) of Nucor;

(9) if it is not a broker-dealer, that it is not engaged in, and does not intend to engage in, a distribution of the New Notes; and

(10) if it is a Participating Broker-Dealer that will receive New Notes for its own account in exchange for Existing Notes that were acquired as a result of market-making activities or other trading activities, then it will deliver, or, to the extent permitted by applicable law, make available to purchasers, a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes.

Unless otherwise indicated in the boxes entitled “Special Issuance and Payment Instructions” and “Special Delivery Instructions” below, any Existing Notes not exchanged will be credited to the account maintained at DTC (specified above in the box entitled “Method of Delivery”). Similarly, unless otherwise instructed in the box entitled “Special Issuance and Payment Instructions” below, New Notes to be issued in exchange for Existing Notes will be credited to the DTC account of the undersigned or the undersigned’s custodian as specified above in the box entitled “Method of Delivery.”

The undersigned understands that the delivery and surrender of the Existing Notes is not effective, and the risk of loss of the Existing Notes does not pass to the Exchange Agent, until receipt by the Exchange Agent of this Letter of Transmittal (or a manually executed facsimile hereof), properly completed and duly executed, or a properly transmitted agent’s message via ATOP, together with all accompanying evidences of authority and any other required documents in form satisfactory to Nucor. All questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of any tendered Existing Notes pursuant to the procedures described above will be determined by Nucor in its sole discretion, which determination will be final and binding on all parties.

The representations and warranties and agreements of a holder tendering Existing Notes on the date of tender shall be deemed to be repeated and reconfirmed on and as of the Expiration Date. For purposes of this Letter of Transmittal, the “beneficial owner” of any Existing Notes means any holder that exercises investment discretion with respect to such Existing Notes.

INSTRUCTIONS

FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1. Delivery of Letter of Transmittal and Existing Notes.

This Letter of Transmittal is to be completed by tendering holders of Existing Notes if Existing Notes are to be tendered by effecting a book-entry transfer into the Exchange Agent’s account at DTC and instructions will not be transmitted through ATOP.

Holders who tender their Existing Notes through ATOP procedures shall be bound by, but need not complete and send to the Exchange Agent, this Letter of Transmittal. Accordingly, a Letter of Transmittal need not accompany tenders effected through ATOP with use of an “agent’s message.”

A book-entry transfer into the Exchange Agent’s account at DTC of all Existing Notes delivered electronically as well as a properly completed and duly executed Letter of Transmittal (or a manually executed facsimile thereof) or a properly transmitted agent’s message through ATOP, and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent at its address set forth herein at or prior to the Expiration Date.

Any financial institution that is a participant in DTC may electronically transmit its acceptance of the Exchange Offer by causing DTC to transfer Existing Notes to the Exchange Agent in accordance with ATOP procedures for such transfer at or prior to the Expiration Date. The Exchange Agent will make available its general participant account at DTC for the Existing Notes for purposes of the Exchange Offer.

Delivery of a Letter of Transmittal to DTC will not constitute valid delivery to the Exchange Agent. No Letter of Transmittal should be sent to Nucor, the Trustee or DTC. Delivery of a Letter of Transmittal and all other required documents should only be made to the Exchange Agent.

The method of delivery of this Letter of Transmittal, the Existing Notes and all other required documents, including delivery through DTC and any agent’s message delivered through ATOP, is at the option and risk of the tendering holder. If delivery is by mail, registered mail, with return receipt requested and properly insured, is recommended. Instead of delivery by mail, it is recommended that holders use an overnight or hand delivery service. In all cases, holders should allow sufficient time to assure delivery to the Exchange Agent by the Expiration Date.

Neither Nucor nor the Exchange Agent is under any obligation to notify any tendering holder of Existing Notes of Nucor’s acceptance of tendered Existing Notes prior to the Expiration Date.

2. Delivery of the New Notes.

New Notes to be issued according to the terms of the Exchange Offer, if consummated, will be delivered in book-entry form. The appropriate DTC participant name and number (along with any other required account information) needed to permit such delivery must be provided in the table entitled “Method of Delivery.” Failure to do so will render a tender of the Existing Notes defective, and Nucor will have the right, which it may waive, to reject such delivery. Holders that anticipate participating in the Exchange Offer other than through DTC are urged to contact promptly a bank, broker or other intermediary (that has the capability to hold securities custodially through DTC) to arrange for receipt of New Notes delivered pursuant to the Exchange Offer and to obtain the information necessary to complete the table.

3. Special Issuance and Payment Instructions and Special Delivery Instructions.

Tendering holders of Existing Notes should indicate in the applicable box the appropriate DTC participant name and number, if different from the DTC participant name and number of the person signing this Letter of Transmittal. In the case of issuance in a different name, the employer identification or social security number of the person named also must be indicated. Holders tendering Existing Notes by book-entry transfer may request that Existing Notes not exchanged be credited to such account maintained at DTC as such holder may designate hereon. If no such instructions are given, such Existing Notes not exchanged will be returned to the account maintained at DTC of the person signing this Letter of Transmittal.

10

4. Tender Amounts.

Tendering holders of Existing Notes must tender Existing Notes in principal amounts equal to the minimum authorized denomination of $2,000 and integral multiples of $1,000 in excess thereof, as set forth under the heading “The Exchange Offer—Minimum Authorized Denominations” in the Prospectus. Book-entry transfers of Existing Notes to the Exchange Agent should be made in the exact principal amount of Existing Notes tendered. No tender of Existing Notes will be accepted if it results in the issuance of less than $2,000 aggregate principal amount of New Notes.

5. Signatures on Letter of Transmittal; Guarantee of Signatures.

If this Letter of Transmittal is signed by the registered holder of the Existing Notes tendered hereby, the signature must correspond exactly with the name as written on DTC’s security position listing as the owner of such Existing Notes, without any change whatsoever. If any of the Existing Notes tendered hereby are held by two or more registered holders, all of the registered holders must sign this Letter of Transmittal.

If any tendered Existing Notes are owned of record by two or more joint owners, all of such owners must sign this Letter of Transmittal. If this Letter of Transmittal is signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or other persons acting in a fiduciary or representative capacity, such persons should so indicate when signing and, unless waived by Nucor, evidence satisfactory to Nucor of their authority to so act must be submitted with this Letter of Transmittal.

Any beneficial owner of Existing Notes tendered hereby who is not a holder of such Existing Notes must arrange with the person who is the holder or such holder’s assignee or nominee to execute and deliver this Letter of Transmittal on behalf of such beneficial owner. If any Existing Notes to be tendered have different holders, it will be necessary to complete, sign and submit as many separate copies of this Letter of Transmittal and any necessary accompanying documents as there are different holders.

All signatures on this Letter of Transmittal must be guaranteed by a recognized participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program (each, a “Medallion Signature Guarantor”), unless the Existing Notes and this Letter of Transmittal are delivered (i) by a registered holder (or by a participant in DTC whose name appears on a security position listing as the owner of such Existing Notes) who has not completed any of the boxes entitled “Special Issuance and Payment Instructions” or “Special Delivery Instructions” on this Letter of Transmittal or (ii) for the account of an Eligible Guarantor Institution (as defined below). If the tendered Existing Notes are registered in the name of a person other than the signer of this Letter of Transmittal, then the signature on this Letter of Transmittal must be guaranteed by a Medallion Signature Guarantor as described above.

An “Eligible Guarantor Institution” is one of the following firms or other entities identified in Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended (as the terms are used in Rule 17Ad-15): (i) a bank; (ii) a broker, dealer, municipal securities dealer, municipal securities broker, government securities dealer or government securities broker; (iii) a credit union; (iv) a national securities exchange, registered securities association or clearing agency; or (v) a savings association.

6. Transfer Taxes.

Holders who tender their Existing Notes for New Notes will not be obligated to pay any transfer taxes in connection with the exchange. If, however, New Notes are to be delivered to, or are to be issued in the name of, any person other than the registered holder of the Existing Notes tendered hereby, or if tendered Existing Notes are registered in the name of any person other than the person signing this Letter of Transmittal, or if a transfer tax is imposed for any reason other than the exchange of Existing Notes in connection with the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering holder.

11

7. Validity of Tenders.

All questions concerning the validity, form, eligibility (including time of receipt), acceptance and withdrawal of any tendered Existing Notes will be determined by Nucor in its sole discretion, which determination will be final and binding on all parties. Nucor reserves the absolute right to reject any and all tenders of Existing Notes not in proper form or any Existing Notes the acceptance for exchange of which may, in the opinion of its counsel, be unlawful. Nucor also reserves the absolute right to waive any defect or irregularity in tenders of Existing Notes, whether or not similar defects or irregularities are waived in the case of other tendered Existing Notes. The interpretation of the terms and conditions by Nucor will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Existing Notes must be cured within such time as Nucor shall determine. None of Nucor, the Exchange Agent or any other person will be under any duty to give notification of defects or irregularities with respect to tenders of Existing Notes, nor shall any of them incur any liability for failure to give such notification.

Tenders of Existing Notes will not be deemed to have been made until such defects or irregularities have been cured or waived. Any Existing Notes received by the Exchange Agent that are not validly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the Exchange Agent without cost to the holders of the Existing Notes, unless otherwise provided in this Letter of Transmittal, promptly following the Expiration Date or the withdrawal or termination of the Exchange Offer.

8. Waiver of Conditions.

Nucor reserves the absolute right to amend or waive any or all of the conditions to the Exchange Offer described in the Prospectus, at any time to the extent legally permitted.

9. Withdrawal of Tenders.

Tenders of Existing Notes may be withdrawn only pursuant to the procedures and subject to the terms set forth in the Prospectus under the heading “The Exchange Offer—Withdrawal of Tenders.” Tenders of Existing Notes may be withdrawn at any time at or prior to the Withdrawal Deadline but not thereafter, unless the Withdrawal Deadline is extended by Nucor or otherwise required by law, and only in accordance with the procedures set forth in the Prospectus under the heading “The Exchange Offer—Withdrawal of Tenders.” Contact the Exchange Agent for a form of withdrawal and revocation.

10. No Conditional Tenders; No Guaranteed Delivery Procedures.

Nucor will not accept any alternative, conditional, irregular or contingent tenders. By executing this Letter of Transmittal (or a manually executed facsimile hereof) or by transmitting an agent’s message via ATOP, you waive any right to receive notice of the acceptance of Existing Notes tendered hereby for exchange.

No guaranteed delivery procedures are being offered in connection with the Exchange Offer, so the undersigned must effect valid tenders of its Existing Notes at or prior to the Expiration Date in order to be eligible to receive New Notes.

11. Requests for Assistance or Additional Copies.

Questions or requests for assistance related to the Exchange Offer and tender procedures and requests for additional copies of the Prospectus and this Letter of Transmittal should be directed to the Exchange Agent and the Information Agent at the address and telephone numbers included herein.

12. Information Reporting and Backup Withholding.

Payments made to holders may be subject to information reporting and backup withholding of U.S. federal income tax, currently at a rate of 24%. Certain holders are not subject to these information reporting and backup withholding requirements. To avoid backup withholding, U.S. Holders that do not otherwise establish an exemption should complete and timely provide to the applicable withholding agent an IRS Form W-9, certifying that the U.S. Holder is a U.S. person, that the taxpayer identification number provided is correct, and that the U.S. Holder is not subject to backup withholding.

12

Failure to provide the correct information on the Form W-9 may subject the tendering U.S. Holder to a penalty imposed by the Internal Revenue Service (the “IRS”). Holders that are non-U.S. persons may be required to complete and timely provide to the applicable withholding agent an IRS Form W-8BEN or IRS Form W-8BEN-E or other applicable IRS W-8 Form, signed under penalties of perjury, attesting to the holder’s foreign status. Payments attributable to accrued but unpaid interest made to a non-U.S. person will be subject to a U.S. federal withholding tax, unless the non-U.S. person provided to the applicable withholding agent proper certification of its non-U.S. status on an applicable IRS Form W-8, and certain other requirements are met. IRS forms may be obtained from the IRS website, www.irs.gov.

As used herein, a “U.S. Holder” for U.S. federal income tax purposes is: (i) a citizen or individual resident of the United States; (ii) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) that is created or organized in or under the laws of the United States, any of the 50 states or the District of Columbia; (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust if (x) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more “U.S. persons” (within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust or (y) the trust has validly elected to be treated as a U.S. person for U.S. federal income tax purposes.

13

In order to tender, a holder of Existing Notes should send or deliver a properly completed and duly executed Letter of Transmittal and any other required documents to the Exchange Agent at its address set forth below or tender pursuant to DTC’s ATOP procedures.

As set forth in the Prospectus, the terms of the New Notes are substantially identical in all material respects to the terms of the Existing Notes, except that the New Notes are registered under the Securities Act of 1933, as amended (the “Securities Act”), and the transfer restrictions, registration rights and payment of additional interest in case of non-registration applicable to the Existing Notes do not apply to the New Notes.

PLEASE NOTE THAT THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON                     , 2021, UNLESS EXTENDED BY THE COMPANY IN ITS SOLE DISCRETION.

THE EXCHANGE OFFER IS NOT CONDITIONED ON A MINIMUM AGGREGATE PRINCIPAL AMOUNT OF EXISTING NOTES BEING TENDERED BY THE HOLDERS OF THE EXISTING NOTES.

We are the holder of record of Existing Notes held by us for your account. As the record holder, we can only tender such Existing Notes pursuant to your instructions. The Letter of Transmittal is furnished to you for your information only and cannot be used by you to tender Existing Notes held by us for your account.

We request instructions as to whether you wish to tender any or all of the Existing Notes held by us for your account pursuant to the terms and conditions of the Exchange Offer by completing, executing and returning to us the attached instructions. We urge you to carefully read the Prospectus and the Letter of Transmittal before instructing us to tender your Existing Notes. We also request that you confirm that we may make the representations contained in the Letter of Transmittal on your behalf.

Pursuant to the Letter of Transmittal, each holder of Existing Notes will represent to the Company that (i) any New Notes to be received by the holder in the Exchange Offer will be acquired in the ordinary course of the holder’s business; (ii) the holder is not participating, and has no arrangement or understanding with any person to participate, in a distribution (within the meaning of the Securities Act) of the New Notes in violation of the provisions of the Securities Act; (iii) the holder is not an “affiliate” (as defined in Rule 405 under the Securities Act) of the Company; and (iv) if the holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, a distribution of the New Notes.

If the tendering holder is a broker-dealer that will receive New Notes for its own account in exchange for Existing Notes that were acquired as a result of market-making activities or other trading activities (whether or not it is also an “affiliate” of the Company within the meaning of Rule 405 under the Securities Act), then such broker-dealer must deliver, or, to the extent permitted by applicable law, make available to purchasers, a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes. The Securities and Exchange Commission (the “SEC”) has taken the position that such broker-dealers may fulfill their prospectus delivery requirements with respect to the New Notes (other than a resale of an unsold allotment from the original sale of the Existing Notes) by using the Prospectus contained in the registration statement of which the Prospectus forms a part that is declared effective by the SEC. We will allow such broker-dealers and other persons, if any, subject to similar prospectus delivery requirements to use the Prospectus in connection with the resale of such New Notes, subject to certain limitations.

Very truly yours,
