SCHEDULE 13D

Item 1.  Security and Issuer

The Schedule 13D filed with the Securities and Exchange Commission on January 13, 2012 (as amended, the “Initial 13D”), by the Reporting Persons with respect to the shares of Common Stock, par value $0.01 (the “Shares”), issued by CVR Energy, Inc. (the “Issuer”), is hereby amended to furnish the additional information set forth herein. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Initial 13D.

Item 4. Purpose of Transaction

Item 4 of the Initial 13D is hereby amended to add the following:

On May 29, 2018, the Issuer announced its intention to commence an offering to exchange up to 37,154,236 common units of CVR Refining, LP for shares of the Issuer’s common stock at an exchange ratio of one common unit of CVR Refining, LP for 0.6335 shares of the Issuer’s common stock, par value $0.01 per share, upon the terms and subject to the conditions set forth in a prospectus/offer to exchange that was filed with the Securities and Exchange Commission on the date hereof as a part of the Issuer’s registration statement on Form S-4 (“registration statement”) and certain of the Reporting Persons’ Tender Offer Statement on Schedule TO. The commencement of the contemplated offer is subject to the effectiveness of the registration statement.

The consummation of the contemplated exchange is subject to the Issuer’s stockholders having approved, as and to the extent required by the New York Stock Exchange, the issuance of shares of the Issuer’s common stock pursuant to the contemplated offer. The Reporting Persons own approximately 82.0% of the outstanding common stock of the Issuer and intend to approve the issuance of the shares of the Issuer’s common stock pursuant to the offer.

Icahn Enterprises Holdings L.P. and American Entertainment Properties Corp. directly own 3,750,000 common units and 2,000,000 common units of CVR Refining, LP, respectively, representing approximately 2.5% and 1.4% of the outstanding common units of CVR Refining, LP, respectively. Neither Icahn Enterprises Holdings L.P. nor American Entertainment Properties Corp. will exchange its common units of in the contemplated offer. Collectively, these 5,750,000 common units represent approximately 3.9% of the outstanding common units of CVR Refining, LP.

Assuming the maximum number of 37,154,236 common units are properly tendered and exchanged by the Issuer, the Reporting Persons and entities affiliated with the Reporting Persons (including the Issuer) will hold 95% of the outstanding common units of CVR Refining, LP. The contemplated offer offer is conditioned upon, among other things, a sufficient number of common units of CVR Refining, LP having been properly tendered and not validly withdrawn such that, following consummation of the exchange, the Reporting Persons and entities affiliated with the Reporting Persons (including the Issuer) will own more than 80% of the common units of CVR Refining, LP.

Pursuant to the partnership agreement of CVR Refining, LP, once the general partner of CVR Refining, LP and its affiliates (which affiliates include the Reporting Persons and the Issuer) own more than 80% of the common units of CVR Refining, LP, the general partner and its affiliates will have the right, but not the obligation, to purchase all, but not less than all, of the common units of CVR Refining, LP held by unaffiliated unitholders of CVR Refining, LP at a price not less than their then-current market price, as calculated pursuant to the terms of the partnership agreement.

Accordingly, the Reporting Persons and the Issuer will be entitled to exercise this call right after the consummation of the contemplated exchange. Pursuant to the partnership agreement, the general partner is not obligated to obtain a fairness opinion regarding the value of the common units of CVR Refining, LP to be repurchased by it upon exercise of the call right. Pursuant to the partnership agreement, the general partner may use its own discretion, free of fiduciary duty restrictions, in determining whether to exercise the call right. The Reporting Persons and the Issuer have no current plans to exercise the call right at this time or upon the consummation of the contemplated exchange. However, there can be no assurance that the general

partner and its affiliates will not exercise the call right in the future.
