MIDNIGHT, NEW YORK CITY TIME, ON JANUARY 10, 2012, UNLESS THE

OFFER IS EXTENDED (SUCH DATE AND TIME, AS IT MAY BE EXTENDED, THE

“EXPIRATION DATE”) OR EARLIER TERMINATED.

The Offer is being made by IEP Metals Sub LLC, a Delaware limited liability company (the “Offeror”), and a wholly-owned subsidiary of Icahn Enterprises Holdings L.P., a Delaware limited partnership (“Icahn Enterprises Holdings”), who is a co-bidder, to purchase all of the issued and outstanding shares of common stock, par value $0.01 per share (the “Common Stock”), of Commercial Metals Company (the “Company”), including the associated rights issued pursuant to the Rights Agreement, dated as of July 30, 2011, between the Company and Broadridge Corporate Issuer Solutions, Inc., as Rights Agent, that are issued and outstanding (the “Rights” and, together with the Common Stock, the “Shares”), for $15.00 per share in cash, without interest, less any applicable withholding taxes (the “Offer Price”), upon the terms and subject to the conditions set forth in the Offer to Purchase, dated December 9, 2011 (as it may be amended or supplemented from time to time, the “Offer to Purchase”) and in the related letter of transmittal (which, together with any amendments or supplements hereto or thereto, collectively constitute the “Offer”). The Offeror will pay all charges and expenses of D.F. King & Co., Inc., as Information Agent (the “Information Agent”), and American Stock Transfer & Trust Company, LLC, as Depositary (the “Depositary”), incurred in connection with the Offer. The Offeror will not pay any fees or commissions to any broker or dealer or any other person (other than the Depositary and the Information Agent) in connection with the solicitation of tenders of Shares pursuant to the Offer.

The Offer is not conditioned upon the Offeror obtaining financing or any due diligence review. The Offer is conditioned on there being validly tendered in the Offer and not properly withdrawn prior to midnight New York City time, on January 10, 2012 (the “Expiration Date”, unless the Offeror shall have extended the period during which the Offer is open, in which event “Expiration Date” shall mean the time and date at which the Offer, as so extended by the Offeror, shall expire) that number of Shares which, when added to any Shares already owned by the Offeror, its subsidiaries and their affiliates, represents a majority of the issued and outstanding Shares on a fully diluted basis as of the Expiration Date. The Offer is also subject to: (i) the Rights having been redeemed and otherwise made inapplicable to the Offer and the Offeror and (ii) the Company’s

Board of Directors having taken action such that the provisions of Section 203 of the Delaware General Corporation Law would not, following consummation of the Offer, prohibit, restrict or apply to, any business combination, as defined in Section 203, involving the Company and the Offeror or any affiliate or associate of the Offeror. The Offer is also subject to other customary conditions. See Section 14 of the Offer to Purchase.

Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment), the Offeror will accept for payment and pay for Shares which are validly tendered and not properly withdrawn on or prior to the Expiration Date, promptly after the Expiration Date. In order for Shares to be validly tendered pursuant to the Offer, the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, together with any required signature guarantees, or an Agent’s Message (as defined in the Offer to Purchase) in connection with a book-entry transfer of Shares, and any other documents required by the Letter of Transmittal, must be received by the Depositary at one of its addresses set forth on the back cover of the Offer to Purchase on or prior to the Expiration Date, and either (i) certificates representing tendered Shares, and, if certificates have been issued in respect of Rights prior to the Expiration Time, certificates representing the associated Rights, must be received by the Depositary, or such Shares must be tendered pursuant to the procedure for book-entry transfer set forth below (and confirmation of receipt of such delivery must be received by the Depositary), in each case on or prior to the Expiration Date, or (ii) the guaranteed delivery procedures set forth in the Offer to Purchase must be complied with. No alternative, conditional or contingent tenders will be accepted.

For purposes of the Offer, the Offeror will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered and not properly withdrawn prior to the Expiration Date when, as and if the Offeror gives oral or written notice to the Depositary, as agent for the tendering stockholders, of the Offeror’s acceptance for payment of such Shares. Payment for Shares so accepted for payment will be made by the deposit of the purchase price therefor with the Depositary, which will act as agent for the tendering stockholders for the purpose of receiving such payment from the Offeror and transmitting such payment to tendering stockholders. Rule 14e-1(c) under the Exchange Act requires the Offeror to promptly pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the Offer. The Offeror does not intend to provide a subsequent offering period under Rule 14d-11 of the Exchange Act but reserves the right to do so. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE.

The Offeror expressly reserves the right, in its sole discretion, at any time and from time to time: (i) to extend the period of time during which the Offer is open which may delay acceptance for payment of, and the payment for, any Shares; (ii) to waive any of the conditions to the Offer; or (iii) amend the Offer by increasing the consideration offered, by giving oral or written notice of such extension, waiver or amendment to the Depositary and making a public announcement thereof. In addition, the Offeror may extend the Offer for any period required by any rule, regulation, interpretation or position of the Securities and Exchange Commission (the “SEC”) or its staff or as required by applicable law.

The rights reserved by the Offeror in the preceding paragraphs are in addition to Offeror’s rights pursuant to Section 14 of the Offer to Purchase. Any extension, waiver or amendment of the Offer will be followed as promptly as practicable by public announcement thereof, such announcement in the case of an extension to be issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date, in accordance with the public announcement requirements of Rule 14e-1(d) under the Exchange Act.

If the Offeror makes a material change in the terms of the Offer or the information concerning the Offer or if the Offeror waives a material condition of the Offer, the Offeror will disseminate additional tender offer materials and extend the Offer if and to the extent required by Rules 14d-4(d)(1), 14d-6(c) and 14e-1 under the Exchange Act. The minimum period during which an offer must remain open following material changes in the terms of the Offer or information concerning the Offer, other than a change in price or a change in percentage of securities sought, will depend upon the facts and circumstances, including the relative materiality of the terms or information changes. In the SEC’s view, an offer should remain open for a minimum of five business days

from the date the material change is first published, sent or given to stockholders, and with respect to a change in price or a change in percentage of securities sought, a minimum 10 business day period generally is required to allow for adequate dissemination to stockholders and investor response. Accordingly, if, prior to the Expiration Date, the Offeror decreases the number of Shares being sought or increases the consideration offered pursuant to the Offer, and if the Offer is scheduled to expire at any time earlier than the tenth business day from the date that notice of such increase or decrease is first published, sent or given to stockholders, the Offer will be extended at least until the expiration of such tenth business day. For purposes of the Offer, a “business day” means any day other than a Saturday, Sunday or a federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time.

Tenders of Shares made pursuant to the Offer may be withdrawn at any time prior to the Expiration Date. If all conditions to the Offer have been satisfied on the Expiration Date, the Offeror will deposit with the Depositary the proceeds required to consummate the Offer and will promptly accept for payment and pay for all properly tendered Shares that have not been withdrawn. The Offeror will not accept Shares for payment unless all conditions to the Offer have been satisfied or waived.

For a withdrawal of Shares tendered to be effective, a written, telegraphic, telex or facsimile transmission notice of withdrawal must be timely received by the Depositary at one of its addresses set forth on the back cover of the Offer to Purchase. Any notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name(s) in which the certificate(s) representing such Shares are registered, if different from that of the person who tendered such Shares. If certificates for Shares to be withdrawn have been delivered or otherwise identified to the Depositary, the name of the registered holder and the serial numbers shown on the particular certificates evidencing such Shares to be withdrawn must also be furnished to the Depositary prior to the physical release of the Shares to be withdrawn. The signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution (as defined in the Offer to Purchase) (except in the case of Shares tendered by an Eligible Institution). If Shares have been tendered pursuant to the procedures for book-entry transfer set forth in Section 2 of the Offer to Purchase, any notice of withdrawal must specify the name and number of the account at The Depository Trust Company (“DTC”) to be credited with such withdrawn Shares and must otherwise comply with DTC’s procedures.

The receipt by a holder of Shares of cash in exchange for its Shares pursuant to the Offer will be a taxable transaction for United States federal income tax purposes. In general, a holder of Shares will recognize gain or loss equal to the difference between (i) the amount of cash received pursuant to the Offer and (ii) its adjusted tax basis in the Shares exchanged therefor. For a more detailed description of certain United States federal income tax consequences of the Offer, see the Offer to Purchase. Each holder of Shares should consult its tax advisor about the particular tax consequences to such holder of exchanging Shares in the Offer.

The information required to be disclosed by paragraph (d)(1) of Rule 14d-6 of the Rules and Regulations under the Exchange Act is contained in the Offer to Purchase and is incorporated herein by reference.

A request is being made to the Company for the use of its stockholder list and security position listing for the purposes of disseminating the Offer to Purchase (and the related Letter of Transmittal and other relevant materials) to the holders of Shares. Upon compliance by the Company with such request, the Offer to Purchase, the related Letter of Transmittal and other relevant materials will be mailed to record holders of Shares and will be furnished to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing, for subsequent transmittal to beneficial owners of Shares.
