Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On April 18, 2012, CVR Energy, Inc. (the “Company”) entered into a Transaction Agreement (the “Transaction Agreement”) among the Company, IEP Energy LLC (the “Offeror”), and each of the other parties listed on the signature pages thereto, each of whom is an affiliate of the Offeror, and Carl C. Icahn (collectively with the Offeror, the “Offeror Parties”).

Pursuant to the Transaction Agreement, no later than the third business day following the date of the Transaction Agreement, the Offeror will amend in accordance with the terms of the Transaction Agreement its pending tender offer (the “Offer”) to purchase all of the issued and outstanding shares of the Company’s common stock (the “Shares”) for a price of $30 per Share in cash, without interest, less any applicable withholding taxes, plus one non-transferable contingent cash payment right for each Share, which represents the contractual right to receive an additional cash payment per Share if a definitive agreement for the sale of the Company is executed within fifteen months following the expiration of the offer and such transaction closes (a “CCP”). The Offer, as amended, will expire at 11:59 p.m., New York City time, on the date that is the later of (i) ten business days after the date the Offer is amended, or (ii) such later date as may be required to resolve any comments made by the Securities and Exchange Commission (the “SEC”) in respect of the Offeror’s tender offer (the “Expiration Date”).

The Offer will be conditioned upon there being validly tendered (including pursuant to notices of guaranteed delivery) and not properly withdrawn, as of immediately prior to 11:59 p.m. on the Expiration Date, at least 31,661,040 Shares, which when added to the Shares already owned by the Offeror and its affiliates, represents a majority of the Shares (the “Minimum Condition”). The Transaction Agreement provides that if the Minimum Condition is not satisfied as of immediately prior to 11:59 p.m. on the Expiration Date, and the Company has complied in all material respects with its obligations under the Transaction Agreement, the Offeror Parties must immediately terminate the Offer and discontinue their previously announced intention to replace all nine directors on the Company’s board of directors (the “Board”) at the Company’s 2012 annual meeting of stockholders (the “2012 Annual Meeting”) and will not present any other proposal for consideration at the 2012 Annual Meeting.

If, following the closing of the Offer, the Minimum Condition is satisfied but the Offeror holds less than 90% of the outstanding Shares, the Transaction Agreement requires the Offeror to provide for a ten business day subsequent offering period during which stockholders who did not previously tender will have a second opportunity to tender their Shares for the same consideration of $30 per share plus the CCP (the “Subsequent Offering Period”). If, following the closing of the Offer or the Subsequent Offering Period, the Offeror holds at least 90% of the outstanding Shares, the Offeror is required to cause a short-form merger of the Company under Section 253 of the Delaware General Corporation Law (the “Short-Form Merger”). If the Short-Form Merger occurs, all remaining Shares will be cancelled and the holders thereof will receive $30 in cash plus a CCP for each share, unless such stockholder elects to assert statutory appraisal rights under Delaware law.

Pursuant to the Transaction Agreement, immediately and contingent upon the closing of the Offer, all but two of the current members of the Board will resign and be replaced by an equal number of directors designated by the Offeror. Effective upon the earlier of the completion of the Subsequent Offering Period and the Short-Form Merger, the remaining two directors will resign from the Board and be replaced by two directors designated by the Offeror.

Promptly following the consummation of the Offer, for a period of 60 days the Company will solicit proposals or offers from third parties to acquire the Company (the “Marketing Period”). If a proposal to acquire the Company for all-cash consideration equal to or exceeding $35 per share is made within the Marketing Period (subject to certain adjustments and qualifications set forth in the Transaction Agreement), the Offeror Parties have agreed to support the proposal, including by voting for or consenting to the proposal if it is submitted to the stockholders of the Company for their vote or consent. Any holder of CCPs will be entitled to any value realized in excess of $30 per Share, net of any investment banking fees, subject to the terms of the CCPs.

The obligation of the Offeror to accept for payment and pay for shares of Company common stock tendered in the Offer will be subject to certain conditions, including, among other things: the absence of a Company Material Adverse Effect (as defined in the terms of the Offer); the absence of injunction relating to the Offer; the Offeror becoming aware of material misstatements or omissions in the Company’s SEC reports; the Company not making any non-ordinary course material enhancements to executive compensation; the Company not making any non-ordinary course acquisitions or dispositions of assets (including completing the previously announced sale of a portion of the Company’s stake in CVR Partners, LP ); the Company not entering into any agreement for a merger, consolidation, business combination or reorganization transaction; and the taking of any actions by the Company intended to cause the failure of a condition to the Offer, except for the Minimum Condition.

The full text of the Transaction Agreement is filed herewith as Exhibit 2.1. The foregoing description of the Transaction Agreement does not purport to describe all of the terms of such agreement, and is qualified in its entirety by reference to the full text of the agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Transaction Agreement contains representations and warranties by the Company and the Offeror Parties which were made only for purposes of that agreement and as of specified dates. The representations, warranties and covenants in the Transaction Agreement were made solely for the benefit of the parties to the Transaction Agreement (except as otherwise specified therein), may be subject to limitations agreed upon by the contracting parties, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. In addition, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Transaction Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.
