PRELIMINARY AND SUBJECT TO CHANGE, DATED JUNE 14, 2018

Offer by
CVR ENERGY, INC.
to Exchange up to 37,154,236 Common Units of
CVR REFINING, LP
for
Shares of CVR Energy, Inc. Common Stock

At an Exchange Ratio of One Common Unit of CVR Refining, LP for
0.6335 Shares of CVR Energy, Inc. Common Stock

         THE OFFER AND THE WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON FRIDAY, JULY 27, 2018, UNLESS THE OFFER IS EXTENDED (SUCH DATE AND TIME, AS THEY MAY BE EXTENDED, THE "EXPIRATION TIME").

         CVR Energy, Inc. ("CVR Energy") is offering to exchange up to 37,154,236 common units of CVR Refining, LP (the "common units") for shares of CVR Energy common stock at an exchange ratio of one common unit for 0.6335 shares of CVR Energy common stock, par value $0.01 per share, upon the terms and subject to the conditions in this prospectus/offer to exchange and accompanying letter of transmittal. This offer is referred to herein as the "offer."

         The purpose of the offer for CVR Energy is to increase its ownership of CVR Refining, LP ("CVR Refining"). As of the date of this prospectus/offer to exchange, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) beneficially owned approximately 69.8% of the common units of CVR Refining. Assuming the maximum number of 37,154,236 common units are validly tendered and exchanged in the offer, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will hold approximately 95% of the outstanding common units of CVR Refining. The offer is conditioned upon, among other things, a sufficient number of common units of CVR Refining having been validly tendered and not properly withdrawn such that, following consummation of the exchange, the general partner of CVR Refining (the "general partner") and entities affiliated with the general partner (which affiliates include CVR Energy and affiliates of Icahn Enterprises L.P.) will own more than 80% of the common units of CVR Refining (the "minimum tender condition").

         Pursuant to the partnership agreement of CVR Refining (the "partnership agreement"), once the general partner and its affiliates own more than 80% of the common units of CVR Refining, 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 held by unaffiliated unitholders of CVR Refining at a price not less than their then-current market price, as calculated pursuant to the terms of the partnership agreement (the "call right").

         Accordingly, the general partner and its affiliates will be entitled to exercise this call right after the consummation of the 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 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 general partner and its affiliates (including CVR Energy and Icahn Enterprises and its affiliates) have no current plans to exercise the call right at this time or upon the consummation of the exchange. However, there can be no assurance that the general partner and its affiliates will not exercise the call right in the future.

         CVR Energy's common stock is listed on the New York Stock Exchange under the symbol "CVI." The common units of CVR Refining are listed on the New York Stock Exchange under the symbol "CVRR." On May 25, 2018, the last full trading day before the date of this prospectus/offer to exchange, the closing price of one share of CVR Energy common stock was $43.61 and the closing price of one common unit of CVR Refining was $22.10. Based on these closing prices and the exchange ratio in the offer, the offer had a per common unit value of $27.63 per common unit, representing a 25% premium over the closing unit price of CVR Refining on May 25, 2018.

         The value of the offer will change as the market prices of CVR Energy common stock and CVR Refining common units fluctuate during the offer period and thereafter, and may therefore be different from the price set forth above at the time you receive your shares of CVR Energy common stock and thereafter. Unitholders are encouraged to obtain current market quotations for shares of CVR Energy common stock and CVR Refining common units prior to making any decision with respect to the offer. See "Risk Factors" and "Comparative Market Price Data and Price Range of the Common Units."

         FOR A DISCUSSION OF CERTAIN FACTORS THAT YOU SHOULD CONSIDER IN CONNECTION WITH THE OFFER, PLEASE CAREFULLY READ THE SECTION CAPTIONED "RISK FACTORS" BEGINNING ON PAGE 18.

         None of CVR Energy, CVR Refining, the information agent or the exchange agent or any of their respective affiliates are making any recommendation to you as to whether to exchange or refrain from exchanging your common units in the offer. You must make your own decision as to whether to exchange your common units and, if so, how many common units to exchange. In doing so, you should carefully read the entire prospectus/offer to exchange, and the information incorporated by reference herein, and related letter of transmittal.

         CVR Energy's obligation to consummate the exchange is subject to specified conditions, including the minimum tender condition, which are more fully described in the section captioned "The Offer—Conditions of the Offer."

         We have not authorized any person to make any recommendation on our behalf as to whether you should exchange or refrain from exchanging your common units or provide any information or to make any representation in connection with the offer other than the information contained or incorporated by reference in this prospectus/offer to exchange. If anyone makes any recommendation or gives any information or representation, you must not rely upon that recommendation, information or representation as having been authorized by us, the exchange agent or the information agent.

         CVR Energy filed a Tender Offer Statement on Schedule TO with the Securities and Exchange Commission (the "SEC") on May 29, 2018 (as it may be amended from time to time, the "Schedule TO").

         Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus/offer to exchange. Any representation to the contrary is a criminal offense.

QUESTIONS AND ANSWERS ABOUT THE OFFER

        The following are some of the questions that you as a holder of common units of CVR Refining may have regarding the offer and answers to those questions. The answers to these questions do not contain all of the details of the offer to the same extent described elsewhere in this prospectus/offer to exchange. We urge you to read the entire prospectus/offer to exchange, including the information incorporated by reference herein, and related letter of transmittal carefully because they contain the full details of the offer.

What is CVR Energy's proposed transaction?

        CVR Energy is offering to acquire up to 37,154,236 outstanding common units of CVR Refining, not otherwise directly or indirectly owned by CVR Energy and its affiliates, in exchange for shares of CVR Energy common stock. As of the date of this prospectus/offer to exchange, there were 147,600,000 common units of CVR Refining outstanding and CVR Energy and entities affiliated with CVR Energy (including affiliates of Icahn Enterprises L.P.) beneficially owned 103,065,764 common units, representing approximately 69.8% of the outstanding common units of CVR Refining.

        If the minimum tender condition is satisfied, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will hold more than 80% of the outstanding common units of CVR Refining, which would permit the general partner and its affiliates to exercise the call right.

        If CVR Energy acquires the maximum 37,154,236 common units in the offer, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will hold approximately 95% of the outstanding common units of CVR Refining.

        See the question below titled "Following the consummation of the exchange, will CVR Refining continue as a public company?"

Who controls CVR Energy?

        CVR Energy is a majority-owned subsidiary of Icahn Enterprises Holdings L.P. Icahn Enterprises L.P. owns a 99% limited partner interest in Icahn Enterprises Holdings L.P. Icahn Enterprises G.P. Inc., which is indirectly owned and controlled by Carl C. Icahn, is the general partner of each of Icahn Enterprises L.P. and Icahn Enterprises Holdings L.P. Icahn Enterprises Holdings L.P. and its subsidiaries own substantially all of the assets and conduct substantially all of the operations of Icahn Enterprises L.P. Icahn Enterprises L.P. is a diversified holding company engaged in the following primary business segments: Investment, Automotive, Energy, Railcar, Gaming, Metals, Mining, Food Packaging, Real Estate and Home Fashion.

        As of the date of this prospectus/offer to exchange, Icahn Enterprises L.P. and its affiliates owned approximately 82.0% of the outstanding common stock of CVR Energy. The following persons may also be deemed to be co-bidders of CVR Energy in making the offer: IEP Energy LLC, IEP Energy Holdings LLC, American Entertainment Properties Corp., Icahn Building LLC, Icahn Enterprises Holdings, Icahn Enterprises G.P. Inc., Beckton Corp. and Carl C. Icahn. The foregoing entities are affiliated with Carl C. Icahn. See Schedule B to this prospectus/offer to exchange for additional information concerning Icahn Enterprises L.P. and its affiliates.

How many common units will CVR Energy exchange in the offer?

        Upon the terms and subject to the conditions of the offer, CVR Energy will exchange up to 37,154,236 common units of CVR Refining, or such lesser number of common units as are validly tendered and not properly withdrawn. If more than 37,154,236 common units are properly tendered for exchange, we will exchange all common units validly tendered on a pro rata basis, except for "odd lots" (lots held by owners of less than 100 common units), which we will exchange on a priority basis.

        The offer is also conditioned upon, among other things, a minimum number of common units having been validly tendered and not properly withdrawn such that, following consummation of the exchange, the general partner and its affiliates will own more than 80% of the outstanding common units of CVR Refining. Common units properly tendered for exchange, but not exchanged pursuant to the offer, will be returned to the tendering unitholders promptly after the offer expires. See "The Offer—Conditions of the Offer."

Following the consummation of the exchange, will CVR Refining continue as a public company?

        Yes. Upon the completion of the exchange in accordance with its terms and conditions, CVR Refining will continue to be listed on the New York Stock Exchange and subject to the periodic reporting requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

        However, if the offer is consummated in accordance with its terms, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will beneficially own over 80% of the outstanding common units of CVR Refining. Pursuant to the partnership agreement of CVR Refining, once the general partner and its affiliates own more than 80% of the common units of CVR Refining, 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 held by unaffiliated unitholders of CVR Refining at a price not less than their then-current market price, as calculated pursuant to the terms of the partnership agreement.

        Accordingly, the general partner and its affiliates will be entitled to exercise this call right after the consummation of the 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 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 general partner and its affiliates (including CVR Energy and Icahn Enterprises and its affiliates) have no current plans to exercise the call right at this time or upon the consummation of the exchange. However, there can be no assurance that the general partner and its affiliates will not exercise the call right in the future.

Do the entities affiliated with Icahn Enterprises L.P. and CVR Energy intend to exchange their common units in the offer?

Neither Icahn Enterprises Holdings L.P. nor American Entertainment Properties Corp. intends to exchange its common units in the offer. Collectively, these 5,750,000 common units represent approximately 3.9% of the outstanding common units of CVR Refining.

What will I receive in exchange for my common units?

        In exchange for each common unit that is exchanged pursuant to the offer, you will receive 0.6335 shares of CVR Energy common stock. The number of shares of CVR Energy common stock into which

        The value of the offer will change as the market prices of CVR Energy common stock and CVR Refining common units fluctuate during the offer period and thereafter, and may be different from the price set forth above at the time you receive your shares of CVR Energy common stock and thereafter.

        You must make your own decision as to whether to exchange your common units. In so doing, you should read the information in this prospectus/offer to exchange, including the information incorporated by reference herein, and in the related letter of transmittal carefully.

What are the conditions of the offer?

        Our obligation to consummate the exchange is subject to several conditions referred to under "The Offer—Conditions of the Offer," including the following:

•

the "registration statement condition"—the registration statement, of which this prospectus/offer to exchange is a part (the "registration statement"), shall have become effective under the Securities Act of 1933, as amended (the "Securities Act"), no stop order suspending the effectiveness of the registration statement shall have been issued and no proceedings for that purpose shall have been initiated or threatened by the SEC, and CVR Energy shall have received all necessary state securities law or "blue sky" authorizations, if any.



•

the "stockholder approval condition"—CVR Energy's stockholders shall have approved, as and to the extent required by the New York Stock Exchange, the issuance of the shares of CVR Energy's common stock pursuant to the offer. On June 13, 2018, approximately 86% of the outstanding common stock of CVR Energy approved the issuance of the shares of CVR Energy common stock pursuant to the offer.



•

the "minimum tender condition"—a sufficient number of common units of CVR Refining shall have been validly tendered and not properly withdrawn such that, following consummation of the exchange, the general partner and entities affiliated with the general partner will own more than 80% of the common units of CVR Refining. As of the date of this prospectus/offer to exchange a minimum of 15,014,237 common units shall be validly tendered and not properly withdrawn to satisfy the minimum tender condition.



•

the "listing condition"—the shares of CVR Energy common stock to be issued pursuant to the offer shall have been authorized for listing on the New York Stock Exchange, subject to official notice of issuance.

        Each of the conditions of the offer are for the sole benefit of CVR Energy and may be asserted or waived by CVR Energy, in whole or in part, at any time and from time to time in our discretion prior to the expiration time.

What are the U.S. federal income tax consequences for an exchanging CVR Refining unitholder?

        The receipt of CVR Energy common stock in exchange for your common units pursuant to the exchange will be a taxable transaction for U.S. federal income tax purposes. A U.S. Holder (as defined in "Certain U.S. Federal Income Tax Consequences") holding common units as a capital asset will generally recognize capital gain or loss on the receipt of CVR Energy common stock in exchange for common units, except to the extent of gain attributable to "unrealized receivables" or "inventory items." A portion of this gain or loss, which could be substantial, will be separately computed and taxed as ordinary income or loss to the extent attributable to unrealized receivables, including depreciation recapture, or to inventory items owned by CVR Refining and its subsidiaries. Passive losses that were not deductible by a U.S. Holder in prior taxable periods because they exceeded the U.S. Holder's share of CVR Refining's income may become available to offset a portion of the gain recognized by such U.S. Holder.

        Please read "Certain U.S. Federal Income Tax Consequences" for a more complete discussion of the expected material U.S. federal income tax consequences of the exchange.

Table of Contents

What are the expected material U.S. federal income tax consequences for a U.S. Holder of the ownership of CVR Energy common stock after the exchange is completed?

        CVR Energy is classified as a corporation for U.S. federal income tax purposes and is subject to U.S. federal income tax on its taxable income. Distributions of cash by CVR Energy to a U.S. Holder with respect to shares of CVR Energy common stock received in the exchange will generally be included in such U.S. Holder's income as ordinary dividend income to the extent of CVR Energy's current or accumulated "earnings and profits," as determined under U.S. federal income tax principles. Distributions of cash in excess of CVI's current and accumulated earnings and profits will be treated as a non-taxable return of capital, reducing a U.S. Holder's adjusted tax basis in such U.S. Holder's shares of CVR Energy common stock and, to the extent the distribution exceeds such U.S. Holder's adjusted tax basis, as capital gain from the sale or exchange of shares of CVR Energy common stock.

        Please read "Certain U.S. Federal Income Tax Consequences" for a more complete discussion of the expected material U.S. federal income tax consequences of owning and disposing of CVR Energy common stock received in the exchange.

Is CVR Energy's financial condition relevant to my decision to exchange in the offer?

        Yes. CVR Energy's financial condition is relevant to your decision to exchange your common units because CVR Refining common units accepted in the offer will be exchanged for shares of CVR Energy common stock. You should therefore consider CVR Energy's financial condition before you decide to become a stockholder of CVR Energy by exchanging your common units in the offer. This prospectus/offer to exchange incorporates by reference financial information regarding CVR Energy and CVR Refining, which you should review carefully. See "Where You Can Find More Information."

What percentage of CVR Energy's shares will exchanging unitholders of CVR Refining own after the offer?

        Based on the exchange ratio for the offer, we estimate that if the maximum of 37,154,236 common units are exchanged pursuant to the offer, exchanging unitholders of CVR Refining would own, in the aggregate, approximately 21.3% of the outstanding shares of CVR Energy common stock and if the minimum of 15,014,237 common units are exchanged pursuant to the offer, exchanging unitholders of CVR Refining would own, in the aggregate, approximately 9.9% of the outstanding shares of CVR Energy common stock after the consummation of the exchange. For a detailed discussion of the assumptions on which this estimate is based, see "The Offer—Ownership of CVR Energy After the Offer."

What is the purpose of the offer and are the interests of CVR Energy and Icahn Enterprises different from my interests as a unitholder?

        The purpose of the offer for CVR Energy is to increase its ownership in CVR Refining.

        As of the date of this prospectus/offer to exchange, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) beneficially owned approximately 69.8% of the common units. Assuming the maximum number of 37,154,236 common units are properly tendered, and are exchanged in the offer, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will beneficially own approximately 95% of the outstanding common units of CVR Refining.

        If the minimum tender condition is satisfied, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will hold more than 80% of the outstanding common units of CVR Refining, which would permit the general partner and its affiliates to exercise the call right.

        CVR Energy's and Icahn Enterprises' interest in the offer may be different from those unitholders being asked to exchange their common units. If your common units are exchanged in the offer, you will

5

Table of Contents

cease to have any direct interest in CVR Refining with respect to such common units, and will not have the opportunity to directly participate in the future earnings or growth of CVR Refining, as a unitholder of CVR Refining, but you will participate indirectly in the performance of CVR Refining to the extent of your ownership of shares of CVR Energy common stock and its ownership of common units of CVR Refining.

Will I participate in the performance of CVR Energy if I exchange my common units in the offer?

        If you exchange your common units, you will participate directly in the performance of CVR Energy as a stockholder of CVR Energy, including any future premium that may be received by stockholders of CVR Energy in connection with a sale or other corporate transaction.

        You will also own shares of a corporation rather than common units in a master limited partnership. See "Certain U.S. Federal Income Tax Consequences" for more information on the tax treatment of owning and disposing of CVR Energy common stock received in the exchange.

How long do I have to decide whether to exchange my common units in the offer?

        You have until 5:00 p.m., New York City time, on Friday, July 27, 2018 to decide whether to exchange your common units in the offer unless we extend the expiration time. If you cannot deliver everything required to make a valid tender to American Stock Transfer & Trust Co., LLC, the exchange agent for the offer, prior to such time, you may be able to use a guaranteed delivery procedure to exchange your common units in the offer, which is described in "The Offer—Guaranteed Delivery."

Can the offer be extended, amended or terminated and under what circumstances?

        We may, in our sole discretion, extend the offer at any time or from time to time. For instance, the offer may be extended if any of the conditions specified in "The Offer—Conditions of the Offer" are not satisfied prior to the expiration time.

        We can amend the offer in our sole discretion at any time prior to the expiration time. We can also terminate the offer prior to the expiration time if the conditions of the offer are not met.

How will I be notified if the offer is extended or the terms of the offer are amended?

        If we decide to extend the offer, we will inform the exchange agent of that fact and will make a public announcement of the extension, not later than 9:00 a.m., New York City time, on the business day after the day on which the offer was scheduled to expire. We will announce any amendment to the offer by making a public announcement of the amendment.

How do I exchange my common units in the offer?

        To exchange your common units in the offer, you must deliver the certificates representing your common units, together with a properly completed and duly executed letter of transmittal, or an agent's message in connection with a book-entry transfer, to the exchange agent not later than the expiration time. If your common units are held in street name by your broker, dealer, commercial bank, trust company or other nominee, such nominee can exchange your common units through The Depository Trust Company. If you cannot deliver everything required to make a valid tender to the exchange agent prior to the expiration time, you may have a limited amount of additional time by having a broker, a bank or other fiduciary that is a member of the Securities Transfer Agents Medallion Program or other eligible institution guarantee that the missing items will be received by the exchange agent within two business days after the expiration time by using the enclosed notice of guaranteed delivery. However, the exchange agent must receive the missing items within that two business day period. For a complete

discussion on the procedures for tendering your units, see "The Offer—Procedure for Tendering" and "The Offer—Guaranteed Delivery."

What happens if more than the maximum of 37,154,236 common units are tendered for exchange?

        If more than 37,154,236 common units are validly tendered for exchange and not properly withdrawn prior to the expiration time, we will exchange common units:

•

first, from all holders of "odd lots" of less than 100 common units who validly tender for exchange all of their common units; and



•

second, from all other unitholders who validly tender common units for exchange, on a pro rata basis.

        Because of "odd lot" priority and proration described above, we may not exchange all of the common units that you validly tender for exchange.

If I own fewer than 100 common units and I tender all of my common units for exchange, will I be subject to proration?

        If you own beneficially or of record fewer than 100 common units in the aggregate, you validly tender all of these common units for exchange and you complete the section entitled "Odd Lots" in the Letter of Transmittal and, if applicable, in the Notice of Guarantee Delivery, we will exchange all of your common units without subjecting them to the proration procedure. See "The Offer—Proration."

Will I have to pay any fee or commission to exchange my common units?

        If you are the record owner of your common units and you exchange your common units in the offer, you will not have to pay any brokerage fees, commissions or similar expenses. If you own your common units through a broker, dealer, commercial bank, trust company or other nominee and your broker, dealer, commercial bank, trust company or other nominee tenders your common units for exchange on your behalf, they may charge a fee for doing so. You should consult your broker, dealer, commercial bank, trust company or other nominee to determine whether any charges will apply.

Until what time can I withdraw tendered common units?

        You can withdraw tendered common units at any time until the offer has expired and, if we have not agreed to accept your common units for exchange by the expiration time, you can withdraw them at any time after that time until we accept your common units for exchange. For a complete discussion on the procedures for withdrawing your common units, see "The Offer—Withdrawal Rights."

How do I withdraw tendered common units?

        To withdraw tendered common units, you must deliver a written notice of withdrawal, or a facsimile of one, with the required information to the exchange agent, while you have the right to withdraw your common units. If you tendered common units for exchange by giving instructions to a broker, dealer, commercial bank, trust company or other nominee, you must instruct the broker, dealer, commercial bank, trust company or other nominee to arrange for the withdrawal of your common units. For a complete discussion on the procedures for withdrawing your common units, see "The Offer—Withdrawal Rights."

When and how will I receive the shares of CVR Energy common stock for my tendered units?

        We will exchange the common units promptly after the expiration time, subject to the terms of the offer and the satisfaction or waiver of the conditions to the offer, as set forth in "The Offer—Conditions of the Offer."

        We do not expect, however, to announce the results of proration and begin exchanging for tendered common units until up to five business days after the expiration time.

        We will exchange your validly tendered and not properly withdrawn common units by depositing shares of CVR Energy common stock with the exchange agent, which will act as your agent for the purpose of receiving shares from CVR Energy and transmitting such shares to you. In all cases, exchange of tendered common units will be made only after timely receipt by the exchange agent of certificates for such common units (or of a confirmation of a book-entry transfer of such common units as described in "The Offer—Procedure for Tendering") and a properly completed and duly executed letter of transmittal and any other required documents for such common units.

Are dissenters' rights available in the offer?

        Dissenters' rights are the rights of unitholders, in certain cases, to receive "fair value" for their units, plus accrued interest, as determined by a statutorily prescribed process, which may include a judicial appraisal process. Dissenters' rights are not available in the offer. See "The Offer—Purpose of the Offer; Dissenters' Rights."

Why does the cover page to this prospectus/offer to exchange state that the offer is subject to change and that the registration statement filed with the SEC is not yet effective?

        We cannot accept for exchange any common units tendered in the offer until the registration statement is declared effective by the SEC and the other conditions to the offer have been satisfied or waived. See "The Offer—Conditions of the Offer."

Where can I find more information on CVR Energy and CVR Refining?

        You can find more information about CVR Energy and CVR Refining from various sources described in the section captioned "Where You Can Find More Information."

Who can I talk to if I have questions about the offer?

RISK FACTORS

        Before making any decision regarding the offer, CVR Refining unitholders should read and consider the risk factors relating to the offer below and the risk factors included in the documents incorporated by reference herein, including risk factors that are described in Part I, Item 1A of CVR Energy's Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and CVR Refining's Annual Report on Form 10-K for the fiscal year ended December 31, 2017. See "Where You Can Find More Information" for the location of information incorporated by reference in this document.

         The exchange ratio for the offer is fixed and will not be adjusted. Because the market price of shares of CVR Energy common stock and CVR Refining common units may fluctuate, CVR Refining unitholders cannot be sure of the market value of the shares of CVR Energy common stock that they will receive in the offer.

        Subject to the terms and conditions of the offer, each outstanding common unit that is accepted for exchange pursuant to the offer will be exchanged for 0.6335 shares of CVR Energy common stock. This exchange ratio is fixed and will not be adjusted in case of any increases or decreases in the price of CVR Energy common stock or CVR Refining common units. If the price of CVR Energy common stock declines (which may occur as a result of a number of reasons (many of which are outside of CVR Energy's control)), CVR Refining unitholders will receive less value for their common units in the offer than the value calculated pursuant to the exchange ratio prior to the expiration time. Because the offer may not be completed until specified conditions have been satisfied or waived (please see "The Offer—Conditions of the Offer"), a significant period of time may pass between the initial filing of the registration statement and Schedule TO and the time that CVR Energy accepts common units for exchange. Therefore, at the time you exchange your common units pursuant to the offer, you will not know the exact market value of the shares of CVR Energy common stock that will be issued to you if CVR Energy accepts your common units for exchange. CVR Refining unitholders are urged to obtain current market quotations for CVR Energy and CVR Refining common units when they consider whether to exchange their common units pursuant to the offer. See "Comparative Market Price Data and Price Range of the Common Units."

         The market price of CVR Energy common stock may decline as a result of the offer.

        The market price of CVR Energy's common stock may decline as a result of the offer. CVR Energy may issue up to 37,154,236 shares of CVR Energy common stock pursuant to the offer. The increase in the number of shares of CVR Energy common stock outstanding may lead to sales of such shares or the perception that such sales may occur, either of which may adversely affect the market for, and the market price of, CVR Energy common stock. The current premium offered as part of the exchange ratio may also adversely affect the market price of CVR Energy common stock.

         CVR Energy will determine, in its reasonable discretion, whether or not the conditions to the offer have been satisfied, and the conditions to the offer are for CVR Energy's sole benefit.

        The satisfaction of any of the conditions to the offer will be determined by CVR Energy in its reasonable discretion. These conditions are for the sole benefit of CVR Energy and its affiliates and may be asserted by CVR Energy in its reasonable discretion regardless of the circumstances giving rise to any of these conditions or may be waived (to the extent legally permissible) by CVR Energy in its reasonable discretion in whole or in part at any time or from time to time before the expiration time, although all conditions to the offer must be satisfied or waived prior to the expiration time. CVR Energy may terminate the offer if any of the conditions to the offer are not satisfied prior to the expiration time, as determined by CVR Energy in its reasonable discretion. CVR Energy also may amend the terms and conditions of the offer. See "The Offer—Conditions of the Offer."

Table of Contents

         Upon your receipt of shares of CVR Energy common stock in the exchange, you will become a stockholder in CVR Energy, which may change some of the rights and privileges you have as a unitholder of CVR Refining.

        CVR Energy is a Delaware corporation governed by the Delaware General Corporation Law, or the "DGCL," and by its certificate of incorporation and bylaws. CVR Refining is a Delaware limited partnership governed by the Delaware Revised Uniform Limited Partnership Act (the "Delaware LP Act") and by its amended and restated limited partnership agreement. Upon your receipt of shares of CVR Energy common stock in the exchange, you will become a stockholder in CVR Energy, which may adversely affect some of the rights and privileges you had as a unitholder of CVR Refining. For a detailed discussion of the rights of CVR Energy stockholders compared to the rights of CVR Refining unitholders, see the section captioned "Comparison of Holders' Rights."

         The exchange is expected to be a taxable transaction for U.S. federal income tax purposes, and the resulting tax liability, if any, will depend in part on the individual circumstances of each holder of the common units.

        Although holders of common units will receive no cash consideration in the exchange, the exchange will be treated as a taxable transaction for U.S. federal income tax purposes. As a result, a U.S. Holder (as defined in "Certain U.S. Federal Income Tax Consequences") of the common units will recognize gain or loss for U.S. federal income tax purposes equal to the difference between such U.S. Holder's amount realized (which will include both the fair market value of the shares of CVR Energy common stock received and such U.S. Holder's share of CVR Refining's nonrecourse liabilities immediately prior to the exchange) and such U.S. Holder's adjusted tax basis in common units. The amount of gain or loss and the character of any such gain or loss recognized by each such holder of common units in the exchange will depend on a number of factors, including the fair market value of CVR Energy common stock on the date of the consummation of the exchange, the allocation of CVR Refining's nonrecourse liabilities among its partners immediately prior to the consummation of the exchange, a U.S. Holder's adjusted tax basis in its common units exchanged, the amount of any gain recharacterized as ordinary by reason of being an "unrealized receivable" of CVR Refining, and the amount of suspended passive losses that may be available to a U.S. Holder to offset a portion of the gain recognized by such holder. As the value of any CVR Energy common stock received in the exchange will not be known until the effective time of the exchange, a U.S. Holder of the common units will not be able to determine its amount realized, and therefore its taxable gain or loss, until such time. In addition, because any prior distributions by CVR Refining received by a U.S. Holder that exceed such holder's allocable share of CVR Refining's net taxable income and gain will have decreased such holder's adjusted tax basis in its common units, the amount, if any, of such prior excess distributions will, in effect, be currently taxable to a U.S. Holder in the year of the consummation of the exchange if the aggregate value of the consideration received in the exchange (including any deemed relief from such U.S. Holder's share of CVR Refining's nonrecourse liabilities) is greater than such holder's adjusted tax basis in its common units. The result described in the preceding sentence would result even if the aggregate value of the consideration received in the exchange is less than a U.S. Holder's original cost basis in its common units. Furthermore, a portion of this gain or loss, which could be substantial, will be separately computed and taxed as ordinary income or loss to the extent attributable to "unrealized receivables" of CVR Refining, including depreciation recapture and depletion recovery, or to "inventory items" owned by CVR Refining and its subsidiaries. For a more complete discussion of U.S. federal income tax consequences of the exchange, see "Certain U.S. Federal Income Tax Consequences."

Table of Contents

         Holders of common units will be required to report and pay U.S. federal income tax on the exchange for the holder's taxable year that includes the date of the exchange, even though a holder will receive no cash consideration with which to pay any potential U.S. federal income tax liability resulting from the exchange.

        Holders of common units will receive no cash consideration in the exchange; however, the receipt of the CVR Energy common stock in exchange for common units in the offer will be treated as a taxable sale by such U.S. Holders of such common units for U.S. federal income tax purposes, and will be required to report and pay U.S. federal income tax on any income and gain realized in such holder's taxable year which includes the date of the exchange. The amount of gain or loss and the character of any such gain or loss recognized by each such holder of common units in the offer will vary depending on such holder's particular situation, including the fair market value of the CVR Energy common stock received by such holder in the exchange, the adjusted tax basis of the common units exchanged by such holder in the exchange, the amount of any gain recharacterized as ordinary by reason of being an "unrealized receivable" or "inventory item," and the amount of any suspended passive losses that may be available to such holder to offset a portion of the gain recognized by such holder.

         The U.S. federal income tax treatment of owning and disposing of CVR Energy common stock received in the exchange will be different than the U.S. federal income tax treatment of owning and disposing of common units.

        CVR Refining is classified as a partnership for U.S. federal income tax purposes and, generally, is not subject to entity-level U.S. federal income taxes. Instead, each holder of common units is required to take into account its distributive share of CVR Refining's items of income, gain, loss and deduction in computing its federal income tax liability, even if no cash distributions are made by CVR Refining to such holder. A pro rata distribution of cash by CVR Refining to a U.S. Holder of common units is generally not taxable for U.S. federal income tax purposes unless the amount of cash distributed is in excess of the holder's adjusted tax basis in its common units. In contrast, CVR Energy is classified as a corporation for U.S. federal income tax purposes and is subject to U.S. federal income tax on its taxable income at the corporate level. Additionally, any distribution of cash by CVR Energy to a U.S. Holder of CVR Energy common stock will generally be included in such holder's income as ordinary dividend income to the extent of CVR Energy's current or accumulated "earnings and profits," as determined under U.S. federal income tax principles, then as a non-taxable return of capital, reducing the adjusted tax basis in the holder's CVR Energy common stock and, to the extent the cash distribution exceeds the holder's adjusted tax basis, as capital gain from the sale or exchange of such CVR Energy common stock. See "Certain U.S. Federal Income Tax Consequences."

PRO FORMA FINANCIAL DATA

        The following unaudited pro forma financial information is provided in narrative form, as there a limited number of easily understood effects on the consolidated statements of operations of CVR Energy for the three months ended March 31, 2018 and year ended December 31, 2017 and the consolidated balance sheet of CVR Energy as of March 31, 2018. Certain assumptions have been made with respect to the pro forma adjustments identified. These assumptions are as follows:

•

The minimum number of 15,014,237 common units are exchanged for 9,511,519 million shares of CVR Energy common stock, resulting in CVR Energy and its affiliates owning approximately 80% of the outstanding common units of CVR Refining; and



•

The second quarter 2018 dividend declaration of $0.75 per share of CVR Energy common stock for a total of $72.3 million was declared and paid on the same day.

        For the three months ended March 31, 2018 and the year ended December 31, 2017, the pro forma effects assume the consummation of the exchange and the declared dividend occurred as of January 1, 2017. For the balance sheet as of March 31, 2018, the pro forma effects assume the consummation of the exchange and the declared dividend occurred on March 31, 2018.

        Pro forma adjustments summarized below give effect to pro forma events that are: (1) directly attributable to the offer and the dividend declaration; (2) factually supportable; and (3) expected to have a continuing impact on the consolidated results of CVR Energy. No pro forma effect has been identified for previously reporting financial information of CVR Refining since the number of common units outstanding is not changing as a result of the offer and declared dividend.

        The unaudited pro forma financial information for CVR Energy has been presented for illustrative purposes only and is not necessarily indicative of the operating results and financial position that would have been achieved had the consummation of the exchange and the declared dividend occurred on the dates indicated. Further, the unaudited pro forma financial information does not purport to project the future operating results or financial position of CVR Energy. The unaudited pro forma financial information have been developed from and should be read in conjunction with the consolidated financial statements and their accompanying notes that are incorporated by reference into this prospectus/offer to exchange.

        For CVR Energy, the pro forma effects on the consolidated statements of operations for the three months ended March 31, 2018 and the year ended December 31, 2017 are as follows:

        For every two million common units exchanged above the amount required for the minimum tender condition, the following pro forma impacts could result:

Pro forma effects on consolidated balance sheet

        In connection with the change in ownership of CVR Refining to 80% on a pro forma basis, certain adjustments to CVR Energy's equity and deferred tax liability balances have been reflected in the table below pursuant to ASC 810 for transactions between entities under common control. The reduction to noncontrolling ownership of CVR Refining will have the pro forma effect of reducing noncontrolling interest as reported in CVR Energy's consolidated balance sheet at March 31, 2018 by $135.0 million. A corresponding increase of $135.0 million has been reflected for pro forma purposes and is comprised of an increase to paid-in-capital and total CVR Energy stockholders' equity of $207.9 million and a reduction of $72.9 million in deferred income tax liability associated with the CVR Energy's change in ownership of CVR Refining.

THE OFFER

General

        CVR Energy is offering to exchange up to 37,154,236 CVR Refining common units at an exchange ratio of one common unit for 0.6335 shares of CVR Energy common stock, upon the terms and subject to the conditions contained in this prospectus/offer to exchange and the accompanying letter of transmittal.You will not receive any fractional shares of CVR Energy common stock in the exchange or cash in lieu of fractional shares. All of your common units exchanged in the offer will be aggregated and you will be issued in respect of all such common units a number of shares of CVR Energy common stock based on the exchange ratio, rounded to the nearest whole number.

        CVR Energy's obligation to exchange shares of CVR Energy common stock for CVR Refining common units pursuant to the offer is subject to several conditions referred to below under "Conditions of the Offer," including the registration statement condition, the stockholder approval condition, the minimum tender condition and the listing condition.

Background of the Offer

        On May 17, 2018 representatives of Icahn Enterprises L.P. contacted representatives of CVR Energy and discussed preliminarily the merits of CVR Energy possibly conducting an exchange offer for the common units.

        On May 24, 2018, the board of directors of CVR Energy met and discussed the terms of the contemplated offer.

        On May 28, 2018, the board of directors of CVR Energy approved the offer.

        On May 29, 2018, CVR Energy filed the registration statement and the Schedule TO.

Reasons for the Offer

        The purpose of the offer for CVR Energy is to increase its ownership of CVR Refining. As of the date of this prospectus/offer to exchange, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) beneficially owned approximately 69.8% of the common units of CVR Refining. Assuming the maximum number of 37,154,236 common units are properly tendered and exchanged by CVR Energy, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will hold 95% of the outstanding common units of CVR Refining. The offer is conditioned upon, among other things, a sufficient number of common units of CVR Refining having been properly tendered and not validly withdrawn such that, following consummation of the exchange, the general partner and entities affiliated with the general partner will own more than 80% of the common units of CVR Refining.

        Pursuant to the partnership agreement of CVR Refining, once the general partner and its affiliates own more than 80% of the common units of CVR Refining, 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 held by unaffiliated unitholders of CVR Refining at a price not less than their then-current market price, as calculated pursuant to the terms of the partnership agreement.

        Accordingly, the general partner and its affiliates will be entitled to exercise this call right after the consummation of the 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 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 general partner and its affiliates (including CVR Energy and Icahn Enterprises and its affiliates) have no current plans to exercise the call right at this time or upon the

consummation of the exchange. However, there can be no assurance that the general partner and its affiliates will not exercise the call right in the future.

Expiration Time of the Offer

        The offer is scheduled to expire at 5:00 p.m., New York City time, on Friday, July 27, 2018, unless extended by CVR Energy. For more information, you should read the discussion below under the caption "The Offer—Extension, Termination and Amendment."

Extension, Termination and Amendment

        Subject to the applicable rules and regulations of the SEC and the terms and conditions of the offer, CVR Energy expressly reserves the right, in its sole discretion, at any time or from time to time, to extend, for any reason, the period of time during which the offer remains open, and CVR Energy can do so by giving oral or written notice of such extension to the exchange agent. If CVR Energy decides to extend the offer, CVR Energy will make an announcement to that effect no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration time. CVR Energy is not making any assurance that it will exercise its right to extend the offer, although it currently intends to do so until all conditions to the offer have been satisfied or waived. During any such extension, all common units previously tendered for exchange and not withdrawn will remain subject to the offer, subject to your right to withdraw your common units. You should read the discussion under "The Offer—Withdrawal Rights" for more details.

        To the extent legally permissible, CVR Energy also reserves the right, in its sole discretion, at any time or from time to time:

•

to delay acceptance for exchange of, or exchange of, any common units pursuant to the offer in order to comply in whole or in part with applicable law;



•

to terminate the offer and not accept or exchange any common units not previously accepted or exchanged, upon the failure of any of the conditions of the offer to be satisfied prior to the expiration time; and



•

to waive any condition or otherwise amend the offer in any respect.

        In addition, even if CVR Energy has accepted for exchange, but not exchanged, common units in the offer, it may terminate the offer and not exchange common units that were previously tendered for exchange if completion of the offer is illegal or if a governmental authority has commenced or threatened legal action related to the offer. However, CVR Energy may not assert a non-regulatory condition after the expiration of the offer.

        CVR Energy will effect any extension, termination, amendment or delay by giving oral or written notice to the exchange agent and by making a public announcement as promptly as practicable thereafter. Subject to applicable law and without limiting the manner in which CVR Energy may choose to make any public announcement, CVR Energy assumes no obligation to publish, advertise or otherwise communicate any such public announcement other than by making a press release.

        CVR Energy acknowledges that Rule 14e-1(c) under the Exchange Act requires CVR Energy to pay the consideration offered in the offer or to return the common units tendered for exchange in the offer promptly after the termination or withdrawal of the offer.

        CVR Energy confirms to you that if it makes a material change in the terms of the offer or the information concerning the offer, or if it waives a material condition of the offer, it will extend the offer to the extent required under the Exchange Act and will comply with the provisions of Rule 14d-4(b) and (d) under the Exchange Act in disseminating information about the material change to CVR Refining unitholders. If, prior to the expiration time, CVR Energy changes the percentage of

31

---

Table of Contents

common units being sought or the consideration offered to you, that change will apply to all holders whose common units are accepted for exchange pursuant to the offer, regardless of whether the common units were tendered for exchange before or after the change. If at the time notice of that change is first published, sent or given to you, the offer is scheduled to expire at any time earlier than the tenth business day from and including the date that such notice is first so published, sent or given, CVR Energy will extend the offer until the expiration of that ten-business-day period. For purposes of the offer, a "business day" means any day other than a Saturday, Sunday or federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time.

        Because the offer is for less than all of the outstanding CVR Refining common units, Rule 14d-11 under the Exchange Act does not permit CVR Energy to provide a subsequent offering period after the expiration of the offer.

Exchange of CVR Refining Common Units; Delivery of CVR Energy Common Stock

        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), CVR Energy will accept for exchange, and will exchange, up to 37,154,236 common units validly tendered and not properly withdrawn promptly after the expiration time. In addition, subject to applicable rules and regulations of the SEC, CVR Energy expressly reserves the right to delay acceptance for exchange of, or the exchange of, common units in order to comply with any applicable law. In all cases, exchange of common units tendered and accepted for exchange pursuant to the offer will be made only after timely receipt by the exchange agent of certificates for those common units (or a confirmation of a book-entry transfer of those common units in the exchange agent's account at The Depository Trust Company, referred to as "DTC"), a properly completed and duly executed letter of transmittal and any other required documents.

        For purposes of the offer, CVR Energy will be deemed to have accepted for exchange common units validly tendered and not properly withdrawn as, if and when it notifies the exchange agent of its acceptance of the tenders of those common units pursuant to the offer. The exchange agent will deliver CVR Energy common stock in exchange for common units pursuant to the offer promptly after receipt of such notice. The exchange agent will act as your agent for the purpose of receiving CVR Energy common stock and transmitting such shares to you.

        If CVR Energy does not accept any tendered common units for exchange pursuant to the terms and conditions of the offer for any reason (including common units not accepted because of proration), or if certificates are submitted for more common units than are tendered, CVR Energy will return certificates for such unexchanged common units without expense to the tendering unitholder or, in the case of common units tendered by book-entry transfer of such common units into the exchange agent's account at DTC pursuant to the procedures set forth below in the section entitled "The Offer—Procedure for Tendering," those common units will be credited to an account maintained within DTC promptly following expiration or termination of the offer.

        CVR Energy reserves the right to transfer or assign, in whole or from time to time in part, to one or more of its affiliates, the right to exchange all or any portion of the common units tendered pursuant to the offer, but any such transfer or assignment will not relieve CVR Energy of its obligations under the offer or prejudice the rights of tendering unitholders to exchange common units validly tendered and accepted for exchange pursuant to the offer.

No Fractional Shares of CVR Energy Common Stock

        You will not receive any fractional shares of CVR Energy common stock in the exchange or cash in lieu of fractional shares. All of your common units exchanged in the offer will be aggregated and

32

---

Table of Contents

you will be issued in respect of all such common units a number of shares of CVR Energy common stock based on the exchange ratio, rounded to the nearest whole number.

Proration

        If more than the maximum of 37,154,236 common units are validly tendered for exchange and not properly withdrawn before the expiration time, CVR Energy will, upon the terms and subject to the conditions of the offer, accept common units for exchange on a pro rata basis, except for "odd lots" (lots held by owners of less than 100 common units), which we will exchange on a priority basis set forth below:

•

first, upon the terms and subject to the conditions of the offer, we will exchange all common units validly tendered for exchange and not properly withdrawn by any odd lot holder who:



•

validly tenders for exchange and does not properly withdraw all common units owned beneficially of record by such holder (tenders for exchange of less than all of the common units owned by such holder will not qualify for this priority); and



•

completes the section entitled "Odd Lots" in the Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery;

and;

•

second, we will exchange all other common units validly tendered for exchange on a pro rata basis with appropriate adjustments to avoid exchange of fractional common units, as described below.

        Because of the "odd lot" priority and proration provisions described above, CVR Energy may not exchange all of the common units validly tendered and not properly withdrawn.

        To qualify for this preference, an Odd Lot Holder must properly tender for exchange all common units owned by the Odd Lot Holder in accordance with the procedures described in "The Offer—Procedures for Tendering." Odd Lots will be accepted for exchange before any proration of the exchange of other tendered common units. This preference is not available to partial tenders or to beneficial or record holders of an aggregate of 100 or more common units, even if these holders have separate accounts or certificates representing fewer than 100 common units. By tendering for exchange in the offer, an Odd Lot Holder who holds common units in its name and tenders for exchange its common units directly to the Exchange Agent would not only avoid the payment of brokerage commissions, but also would avoid any applicable odd lot discounts in an exchange of the holder's common units. Any Odd Lot Holder wishing to tender all of its common units for exchange pursuant to the offer should complete the section entitled "Odd Lots" in the Letter of Transmittal and, if applicable, in the Notice of Guaranteed Delivery.

        If proration of tendered common units is required, CVR Energy will determine the proration factor promptly following the expiration time. Proration for each unitholder, other than odd lot holders, will be based on the ratio of the number of common units validly tendered and not properly withdrawn by such unitholder to the total number of common units validly tendered and not properly withdrawn by all unitholders, other than odd lot holders. Because of the difficulty in determining the number of common units validly tendered, including common units tendered by guaranteed delivery procedures as described below, and not properly withdrawn, CVR Energy does not expect that it will be able to announce the final proration factor until five business days after the expiration time. The preliminary results of any proration will be announced by press release promptly after the expiration time. CVR Refining unitholders may obtain preliminary proration information from the information agent or exchange agent for the offer and may be able to obtain this information from their brokers.

Procedure for Tendering

        For you to validly tender common units pursuant to the offer, either (a) a properly completed and duly executed letter of transmittal, along with any required signature guarantees, or an agent's message in connection with a book-entry transfer, and any other required documents, must be received by the exchange agent at one of its addresses set forth on the back cover of this prospectus/offer to exchange, and certificates for tendered common units must be received by the exchange agent at such address or those common units must be tendered pursuant to the procedures for book-entry transfer set forth below (and a confirmation of receipt of such tender, referred to as a "book-entry confirmation," must be received), in each case, before the expiration time, or (b) you must comply with the guaranteed delivery procedures set forth below under "The Offer—Guaranteed Delivery."

        The term "agent's message" means a message transmitted by DTC to, and received by, the exchange agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgment from the DTC participant tendering the CVR Refining common units that are the subject of such book-entry confirmation, that such participant has received and agrees to be bound by the terms of the letter of transmittal and that CVR Energy may enforce that agreement against such participant.

        The exchange agent has established accounts with respect to the common units at DTC in connection with the offer, and any financial institution that is a participant in DTC may make book-entry delivery of common units by causing DTC to transfer such shares into the exchange agent's account in accordance with DTC's procedure for such transfer. However, although delivery of common units may be effected through book-entry transfer at DTC, the letter of transmittal with any required signature guarantees, or an agent's message, along with any other required documents, must, in any case, be received by the exchange agent at one of its addresses set forth on the back cover of this prospectus/offer to exchange prior to the expiration time, or the guaranteed delivery procedures described below must be followed. CVR Energy cannot assure you that book-entry delivery of common units will be available. If book-entry delivery is not available, you must tender common units by means of delivery of unit certificates or pursuant to the guaranteed delivery procedures set forth below under "The Offer—Guaranteed Delivery."

        Signatures on all letters of transmittal must be guaranteed by an eligible institution (as defined below), except (1) in cases in which common units are tendered by a registered holder of common units who has not completed the box entitled "Special Issuance Instructions" or the box entitled "Special Delivery Instructions" on the letter of transmittal or (2) if common units are tendered for the account of a financial institution that is a member of the Securities Transfer Agents Medallion Program or by any other "eligible guarantor institution," as that term is defined in Rule 17Ad-15 under the Exchange Act (each of the foregoing is referred to as an "eligible institution"). Most banks, savings and loan associations and brokerage houses are able to effect these signature guarantees for you.

        If the certificates for common units are registered in the name of a person other than the person who signs the letter of transmittal, or if the offer consideration is to be delivered, or certificates for unexchanged common units are to be issued, to a person other than the registered holder(s), the certificates for the units must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name or names of the registered owner or owners appear on the certificates, with the signature(s) on the certificates or stock powers guaranteed by an eligible institution.

        In all cases, CVR Energy will exchange common units tendered and accepted for exchange pursuant to the offer only after timely receipt by the exchange agent of certificates for common units (or timely confirmation of a book-entry transfer of such securities into the exchange agent's account at DTC as described above), properly completed and duly executed letter(s) of transmittal (or an agent's message in connection with a book-entry transfer) and any other required documents.

Table of Contents

        By executing a letter of transmittal as set forth above, you irrevocably appoint CVR Energy's designees as your attorneys-in-fact and proxies, each with full power of substitution, to the full extent of your rights with respect to your common units tendered and accepted for exchange by CVR Energy and with respect to any and all other common units and other securities issued or issuable in respect of such common units on or after the expiration time. That appointment is effective, and voting rights will be affected, when and only to the extent that CVR Energy deposits with the exchange agent the shares of its common stock in consideration for the common units that you have tendered. All such proxies will be considered coupled with an interest in the tendered common units and therefore will not be revocable. Upon the effectiveness of such appointment, all prior proxies that you have given will be revoked, and you may not give any subsequent proxies (and, if given, they will not be deemed effective). CVR Energy's designees will, with respect to the common units for which the appointment is effective, be empowered, among other things, to exercise all of your voting and other rights as they, in their sole discretion, deem proper at any annual, special or adjourned meeting of CVR Refining's unitholders or otherwise. CVR Energy reserves the right to require that, in order for common units to be deemed validly tendered, immediately upon the exchange of those shares, CVR Energy must be able to exercise full voting rights with respect to those common units.

        THE METHOD OF DELIVERY OF CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, IS AT YOUR OPTION AND RISK, AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. IF DELIVERY IS BY MAIL, CVR ENERGY RECOMMENDS REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO ENSURE TIMELY DELIVERY.

        TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING, YOU MUST PROVIDE THE EXCHANGE AGENT WITH YOUR CORRECT TAXPAYER IDENTIFICATION NUMBER AND CERTIFY WHETHER YOU ARE SUBJECT TO BACKUP WITHHOLDING BY PROVIDING A PROPERLY COMPLETED IRS FORM W-9 (IN THE CASE OF U.S. HOLDERS) OR THE APPROPRIATE IRS FORM W-8 (IN THE CASE OF NON-U.S. HOLDERS). ANY AMOUNT WITHHELD UNDER THE U.S. BACKUP WITHHOLDING RULES IS NOT AN ADDITIONAL TAX AND WILL GENERALLY BE ALLOWED AS A REFUND OR CREDIT AGAINST A HOLDER'S U.S. FEDERAL INCOME TAX LIABILITY PROVIDED THAT THE REQUIRED INFORMATION IS TIMELY FURNISHED TO THE IRS.

Guaranteed Delivery

        If you wish to exchange common units pursuant to the offer and your certificates are not immediately available or you cannot deliver the certificates and all other required documents to the exchange agent prior to the expiration time or complete the procedure for book-entry transfer on a timely basis, your common units may nevertheless be tendered, as long as all of the following conditions are satisfied:

•

you make your tender by or through an eligible institution;



•

a properly completed and duly executed notice of guaranteed delivery, substantially in the form made available by CVR Energy, is received by the exchange agent as provided below prior to the expiration date; and



•

the certificates for all tendered common units (or a confirmation of a book-entry transfer of such securities into the exchange agent's account at DTC as described above), in proper form for transfer, together with a properly completed and duly executed letter of transmittal with any required signature guarantees (or, in the case of a book-entry transfer, an agent's message) and all other documents required by the letter of transmittal, are received by the exchange agent within two trading days after the date of execution of such notice of guaranteed delivery

35

Table of Contents

        You may deliver the notice of guaranteed delivery by hand, overnight courier, facsimile transmission or mail to the exchange agent. The notice must include a guarantee by an eligible institution in the form set forth in the notice.

        The tender of common units pursuant to any of the procedures described above will constitute a binding agreement between CVR Energy and you upon the terms and subject to the conditions of the offer.

Matters Concerning Validity and Eligibility

        CVR Energy will determine all questions as to the validity, form, eligibility (including time of receipt) and acceptance for exchange of any tender of common units, in its sole discretion, and its determination will be final and binding to the fullest extent permitted by law. CVR Energy reserves the absolute right to reject any and all tenders of common units that it determines are not in proper form or the acceptance of or exchange for which may, in the opinion of its counsel, be unlawful. CVR Energy also reserves the absolute right to waive any defect or irregularity in the tender of any common units. No tender of common units will be deemed to have been validly made until all defects and irregularities in tenders of common units have been cured or waived. None of CVR Energy, the exchange agent, the information agent or any other person will be under any duty to give notification of any defects or irregularities in the tender of any common units or will incur any liability for failure to give any such notification. CVR Energy's interpretation of the terms and conditions of the offer (including the letter of transmittal and instructions thereto) will be final and binding to the fullest extent permitted by law.

        IF YOU HAVE ANY QUESTIONS ABOUT THE PROCEDURE FOR TENDERING YOUR COMMON UNITS, PLEASE CONTACT THE INFORMATION AGENT AT ITS ADDRESS AND TELEPHONE NUMBERS SET FORTH ON THE BACK COVER OF THIS PROSPECTUS/OFFER TO EXCHANGE.

Withdrawal Rights

        You can withdraw tendered common units at any time until the offer has expired and, if CVR Energy has not agreed to accept your shares for exchange by the expiration time, you can withdraw them at any time after that date until it accepts common units for exchange. If CVR Energy elects to extend the offer, is delayed in its acceptance for exchange of common units or is unable to accept common units for exchange pursuant to the offer for any reason, then, without prejudice to CVR Energy's rights under the offer, the exchange agent may, on behalf of CVR Energy, retain tendered common units, and such common units may not be withdrawn except to the extent that tendering unitholders are entitled to withdrawal rights as described in this section. Any such delay will be by an extension of the offer to the extent required by law. Please see the section of this prospectus/offer to exchange entitled "The Offer—Extension, Termination and Amendment."

        For a withdrawal to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the exchange agent at one of its addresses set forth on the back cover page of this prospectus/offer to exchange. Any such notice of withdrawal must specify the name of the person who tendered the common units to be withdrawn, the number of common units to be withdrawn and the name of the registered holder of such common units, if different from that of the person who tendered such common units. If certificates evidencing common units to be withdrawn have been delivered or otherwise identified to the exchange agent, then, prior to the physical release of such certificates, the serial numbers shown on such certificates must be submitted to the exchange agent and, unless such common units have been tendered by or for the account of an eligible institution, the signature(s) on the notice of withdrawal must be guaranteed by an eligible institution. If common units have been tendered pursuant to the procedure for book-entry transfer as set forth in the section of this

36

---

Table of Contents

prospectus/offer to exchange entitled "The Offer—Procedure for Tendering," any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn common units.

        Withdrawals of common units may not be rescinded. Any common units properly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the offer. However, withdrawn common units may be re-tendered at any time prior to the expiration time by following one of the procedures discussed under the sections entitled "The Offer—Procedure for Tendering" or "The Offer—Guaranteed Delivery."

        CVR Energy will decide all questions as to the form and validity (including time of receipt) of any notice of withdrawal in its sole discretion, and its decision shall be final and binding to the fullest extent permitted by law. None of CVR Energy, the exchange agent, the information agent or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or will incur any liability for failure to give any such notification.

Announcement of Results of the Offer

        CVR Energy will announce by press release the final results of the offer, including whether all of the conditions to the offer have been satisfied or waived and whether CVR Energy will accept the tendered common units for exchange, promptly after expiration time, except as otherwise provided above under "Proration."

Ownership of CVR Energy After the Offer

        Based on the exchange ratio for the offer, CVR Energy estimates that if the maximum 37,154,236 common units are exchanged pursuant to the offer, exchanging CVR Refining unitholders would own, in the aggregate, approximately 21.3% of the outstanding shares of CVR Energy common stock and if the minimum 15,014,237 common units are exchanged pursuant to the offer, exchanging CVR Refining unitholders would own, in the aggregate, approximately 9.9% of the outstanding shares of CVR Energy common stock after the consummation of the exchange.

        This is based on 86,831,050 shares of CVR Energy common stock outstanding as of the date of this prospectus/offer to exchange.

Certain U.S. Federal Income Tax Considerations

        The following is a discussion of the material U.S. federal income tax consequences of the exchange that are applicable to U.S. Holders (as defined below) of the exchange and of acquiring, owning and disposing of shares of CVR Energy common stock received in the exchange. This discussion is limited to U.S. Holders of common units that hold their common units, and will hold their shares of CVR Energy common stock received in the exchange, as capital assets for U.S. federal income tax purposes (generally, property held for investment). This discussion is based upon the Internal Revenue Code of 1986, as amended ("Code"), as well as Treasury regulations (including temporary and proposed regulations), current administrative rulings and judicial decisions thereunder, all as in effect on the date hereof and all of which are subject to change, possibly with retroactive effect. No ruling has been or will be sought from the Internal Revenue Service ("IRS") with respect to any of the tax consequences discussed below. As a result, there can be no assurances that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below.

        The discussion below does not purport to be a complete discussion of all U.S. federal income tax consequences of participating in the offer, and does not address tax consequences that may be relevant to particular holders in light of their individual circumstances, including, without limitation:

•

persons other than U.S. Holders;

37

Table of Contents

•

holders who hold common units or will hold CVR Energy stock in individual retirement accounts;



•

banks, other financial institutions or insurance companies;



•

real estate investment trusts, regulated investment companies (including mutual funds) or other financial conduits;



•

dealers and brokers in stocks and securities or currencies;



•

traders in securities that use a mark-to-market method of tax accounting;



•

tax-exempt entities;



•

certain former citizens or long-term residents of the United States;



•

persons that hold common units or will hold CVR Energy common stock as part of a hedge, straddle, appreciated financial position, conversion or other "synthetic security" or integrated investment or risk reduction transaction for U.S. federal income tax purposes;



•

persons whose "functional currency" is not the U.S. dollar; or



•

persons who do not hold common units or will not hold CVR Energy common stock as a capital asset for U.S. federal income tax purposes.

        If a partnership, or any entity treated as a partnership for U.S. federal income tax purposes, holds common units or will hold CVR Energy common stock, the tax treatment of a partner in such a partnership will generally depend on the status of the partner and the activities of the partnership. A partner in a partnership should consult its own tax advisor as to the consequences of the offer to such partner and such partnership.

        This discussion does not address any tax consequences arising under the net investment income tax or the alternative minimum tax, nor does it address any tax consequences arising under the laws of any state, local, or non-U.S. jurisdiction, or any under U.S. federal laws other than those pertaining to income taxes. This discussion does not address any tax consequences to a holder of common units who does not participate in the offer, including the effects of recent tax reform on partners in partnerships or the exercise of the call right in the future.

        For purposes of this discussion, a U.S. Holder is a beneficial owner of common units or CVR Energy common stock that is for U.S. federal income tax purposes:

(i)

an individual citizen or resident alien of the United States;



(ii)

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;



(iii)

an estate the income of which is subject to U.S. federal income tax regardless of its source; or



(iv)

a trust if: (i) a court within the United States is able to exercise primary jurisdiction over its administration and one or more U.S. persons have the authority to control all substantial decisions of the trust; or (ii) the trust has properly elected under applicable Treasury regulations to be treated as a U.S. person.

        THIS DISCUSSION IS PROVIDED FOR GENERAL INFORMATION ONLY AND IS NOT A COMPLETE ANALYSIS OR DESCRIPTION OF ALL POTENTIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE OR THE RECEIPT, OWNERSHIP AND DISPOSITION OF SHARES OF CVR ENERGY COMMON STOCK RECEIVED IN THE EXCHANGE. EACH HOLDER OF CVR REFINING COMMON UNITS IS STRONGLY URGED

Table of Contents

TO CONSULT WITH AND RELY UPON ITS OWN TAX ADVISOR AS TO THE SPECIFIC FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES TO SUCH HOLDER OF PARTICIPATING (OR NOT) IN THE OFFER AND THE RECEIPT, OWNERSHIP AND DISPOSITION OF SHARES OF CVR ENERGY COMMON STOCK RECEIVED IN THE EXCHANGE, IN ITS OWN PARTICULAR CIRCUMSTANCES.

Assumptions Related to the U.S. Federal Income Tax Treatment of the Offer

        The discussion below assumes that CVR Refining will be classified as a partnership for U.S. federal income tax purposes at the time of the offer. Following the offer, a U.S. Holder of common units that receives CVR Energy common stock will be treated as a stockholder of CVR Energy regardless of the U.S. federal income tax classification of CVR Refining.

Tax Consequences of the Offer to U.S. Holders of CVR Refining Common Units

        This discussion addresses U.S. Holders of common units that participate in the offer. If you are not a U.S. Holder of common units, if you will not be a U.S. Holder of CVR Energy common stock, or if you are a holder of common units and you do not participate in the offer, this discussion does not apply to you, and you should consult your own tax advisor as to the U.S. federal income tax consequences of the offer in your particular circumstances.

Tax Characterization of the Exchange

        The receipt of CVR Energy common stock in exchange for common units pursuant to the exchange generally will be a taxable transaction to U.S. Holders for U.S. federal income tax purposes pursuant to which a U.S. Holder surrenders common units and is relieved of its pro rata share of CVR Refining's nonrecourse liabilities attributable to the common units surrenders (if any), and receives newly issued shares of CVR Energy common stock. The remainder of this discussion assumes that the exchange will be so treated.

Amount and Character of Gain Recognized

        A U.S. Holder who receives CVR Energy common stock in exchange for CVR Refining common units pursuant to the exchange will recognize gain or loss in an amount equal to the sum of the fair market value of the CVR Energy common stock received and such U.S. Holder's share of CVR Refining's nonrecourse liabilities (if any) attributable to the common units surrendered immediately prior to the exchange, over such U.S. Holder's adjusted tax basis in its common units exchanged therefor (which includes such U.S. Holder's share of CVR Refining's nonrecourse liabilities (if any) immediately prior to the exchange).

        A U.S. Holder's tax basis in its common units generally equals the amount such holder paid for such common units plus such holder's share of CVR Refining's nonrecourse liabilities (if any), then increased by such holder's allocable share of CVR Refining's income and gain, and decreased, but not below zero, by actual or deemed distributions by CVR Refining to such holder and by such holder's allocable share of CVR Refining's losses, deductions and expenditures that are not deductible in computing CVR Refining's taxable income and are not required to be capitalized.

        Gain or loss recognized by a U.S. Holder on the exchange will generally be taxable as capital gain or loss, except to the extent of gain attributable to "unrealized receivables" or "inventory items." A portion of this gain or loss, which could be substantial, will be separately computed and taxed as ordinary income or loss to the extent attributable to unrealized receivables, including depreciation recapture and depletion recovery, or to inventory items owned by CVR Refining and its subsidiaries. Under recently enacted Section 199A of the Code, subject to certain limitations and restrictions, an individual holder generally is entitled to a deduction equal to 20% of any such ordinary income to the

39

---

Table of Contents

extent attributable to unrealized receivables or inventory items; however, there is limited interpretive guidance as to the application of Section 199A of the Code, and a U.S. Holder potentially eligible for this deduction should consult with its own tax advisor as to the availability of this deduction in its individual circumstances. Depending on the specific circumstances, ordinary income attributable to unrealized receivables and inventory items may exceed net taxable gain realized on the exchange, may be recognized even if there is a net taxable loss realized on the exchange. Consequently, a U.S. Holder may recognize both ordinary income and capital loss upon the exchange of CVR Refining common units in the exchange. U.S. Holders should consult their own advisors as to the effect of recognizing income in respect of unrealized receivables and inventory items as a result of the exchange.

        Capital gain or loss recognized by a U.S. Holder will generally be long-term capital gain or loss if such holder has held its CVR Refining common units for more than one year as of the consummation of the exchange. If a U.S. Holder is an individual, such long-term capital gain will generally be eligible for reduced rates of taxation. Capital losses recognized by a U.S. Holder may offset capital gains, and, in the case of individuals, no more than $3,000 of ordinary income. Capital losses recognized by U.S. Holders that are corporations only may be used to offset capital gains.

        The amount of gain or loss recognized by each U.S. Holder on the exchange will vary depending on such U.S. Holder's particular situation, including the fair market value of the CVR Energy common stock received by such U.S. Holder in the exchange, the share of nonrecourse liabilities of CVR attributable to the common units surrendered, the adjusted tax basis of the common units exchanged by such U.S. Holder in the exchange, and the amount of any suspended passive losses that may be available to such U.S. Holder to offset a portion of the gain recognized by such U.S. Holder. Passive losses that were not deductible by a U.S. Holder in prior taxable periods because they exceeded such U.S. Holder's share of CVR Refining's income may be deducted in full upon the U.S. Holder's taxable disposition of its entire investment in CVR Refining pursuant to the offer. Each U.S. Holder is strongly urged to consult its own tax advisor with respect to the specific tax consequences of the exchange, taking into account the holder's own particular circumstances.

CVR Refining Items of Income, Gain, Loss and Deduction for the Taxable Period of CVR Refining that Includes the Date of the Exchange

        A U.S. Holder of common units will be allocated its share of CVR Refining's items of income, gain, loss, and deduction for the taxable period of CVR Refining, which includes the date of the exchange in accordance with the terms of the CVR Refining partnership agreement. A U.S. Holder will be subject to U.S. federal income taxes on any such allocated income and gain even if such U.S. Holder does not receive a cash distribution from CVR Refining. Any such income and gain allocated to a U.S. Holder will increase the U.S. Holder's tax basis in the common units held, and therefore will reduce the gain, or increase the loss, recognized by such U.S. Holder resulting from the exchange. Any losses or deductions allocated to a U.S. Holder will decrease the U.S. Holder's tax basis in its common units held, and therefore will increase the gain, or reduce the loss, recognized by such U.S. Holder resulting from the exchange.

Tax Consequences to U.S. Holders of Owning and Disposing of Shares of CVR Energy Common Stock Received Upon Exchange

Tax Basis and Holding Period in Shares of CVR Energy Common Stock Received in the Exchange

        A U.S. Holder's tax basis in the shares of CVR Energy common stock received in the exchange will equal the fair market value of such shares on the date such shares are received. A U.S. Holder's holding period in the shares of CVR Energy common stock received in the exchange will begin on the day after the date of the consummation of the exchange.

Table of Contents

Distributions on Shares of CVR Energy Common Stock

        For U.S. federal income tax purposes, distributions of cash by CVR Energy to a U.S. Holder with respect to shares of CVR Energy common stock received in the exchange will generally be included in such U.S. Holder's income as ordinary dividend income to the extent of CVR Energy's current or accumulated "earnings and profits" as determined under U.S. federal income tax principles. A portion of the cash distributed to CVR Energy stockholders by CVR Energy after the exchange may exceed CVR Energy's current and accumulated earnings and profits. Distributions of cash in excess of CVR Energy's current and accumulated earnings and profits will be treated as a non-taxable return of capital reducing a U.S. Holder's adjusted tax basis in such U.S. Holder's shares of CVR Energy common stock, and, to the extent the distribution exceeds such U.S. Holder's adjusted tax basis, as capital gain from the sale or offer of shares of CVR Energy common stock. Dividends received by a corporate U.S. Holder may be eligible for a dividends received deduction, subject to applicable limitations. Dividends received by an individual U.S. Holder may be taxed at the lower applicable long-term capital gains rate if such dividends are treated as "qualified dividend income" for U.S. federal income tax purposes.

Sale, Exchange, Certain Redemptions or Other Taxable Dispositions of Shares of CVR Energy Common Stock

        Upon the sale, exchange, certain redemptions or other taxable dispositions of shares of CVR Energy common stock received in the exchange, a U.S. Holder will generally recognize capital gain or loss equal to the amount of cash and the fair market value of any other property received upon such taxable disposition of shares of CVR Energy common stock, over the U.S. Holder's adjusted tax basis in such shares of CVR Energy common stock. Such capital gain or loss will be long-term capital gain or loss if the U.S. Holder's holding period in the shares of CVR Energy common stock disposed of is more than twelve months at the time of such taxable disposition. Long-term capital gains of non-corporate taxpayers are generally taxed at reduced rates. Capital losses recognized by a U.S. Holder may offset capital gains, and in the case of individuals, no more than $3,000 of ordinary income. Capital losses recognized by U.S. Holders that are corporations may only be used to offset capital gains.

Information Reporting and Backup Withholding

        Information returns may be required to be filed with the IRS in connection with the exchange, the portion of the CVR Refining taxable year for which a holder holds common units prior to the exchange, and in connection with any distributions made with respect to, or dispositions of, shares of CVR Energy common stock received in the exchange. A U.S. Holder may be subject to U.S. backup withholding on distributions made with respect to, or on payments made pursuant to dispositions of, shares of CVR Energy common stock received in the exchange unless such holder provides proof of an applicable exemption or a correct taxpayer identification number and otherwise complies with the applicable requirements of the backup withholding rules. Any amount withheld under the U.S. backup withholding rules is not an additional tax and will generally be allowed as a refund or credit against the U.S. Holder's U.S. federal income tax liability provided that the required information is timely furnished to the IRS.

Purpose of the Offer

Purpose of the Offer

        The purpose of the offer for CVR Energy is to increase its ownership in CVR Refining.

        As of the date of this prospectus/offer to exchange, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) beneficially owned approximately 69.8% of the common units. Assuming the maximum number of 37,154,236 common units are properly tendered, and are exchanged in the offer, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will beneficially own approximately 95% of the outstanding common units of CVR Refining.

41

---

Table of Contents

        If the minimum tender condition is satisfied, CVR Energy and its affiliates (including affiliates of Icahn Enterprises L.P.) will hold more than 80% of the outstanding common units of CVR Refining, which would permit the general partner and its affiliates to exercise the call right.

        CVR Energy's and Icahn Enterprises' interest in the offer may be different from those unitholders being asked to exchange their common units. If your common units are exchanged in the offer, you will cease to have any direct interest in CVR Refining with respect to such common units, and will not have the opportunity to directly participate in the future earnings or growth of CVR Refining, as a unitholder of CVR Refining, but you will participate indirectly in the performance of CVR Refining to the extent of your ownership of shares of CVR Energy common stock and its ownership of common units of CVR Refining.

        However, if you exchange your common units, you will participate directly in the performance of CVR Energy as a stockholder of CVR Energy, including any future premium that may be received by stockholders of CVR Energy in connection with a sale or other corporate transaction.

        You will also own shares of a corporation rather than common units in a master limited partnership. See "Certain U.S. Federal Income Tax Consequences" for more information on the tax treatment of owning and disposing of CVR Energy common stock received in the exchange.

        The offer is conditioned upon, among other things, a sufficient number of common units of CVR Refining having been validly tendered and not properly withdrawn such that, following consummation of the exchange, the general partner and entities affiliated with the general partner will own more than 80% of the common units of CVR Refining. Pursuant to the partnership agreement of CVR Refining, once the general partner and its affiliates own more than 80% of the common units of CVR Refining, 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 held by unaffiliated unitholders of CVR Refining at a price not less than their then-current market price, as calculated pursuant to the terms of the partnership agreement.

        Accordingly, the general partner and its affiliates will be entitled to exercise this call right after the consummation of the 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 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 general partner and its affiliates (including CVR Energy and Icahn Enterprises and its affiliates) have no current plans to exercise the call right at this time or upon the consummation of the exchange. However, there can be no assurance that the general partner and its affiliates will not exercise the call right in the future.

Dissenters' Rights

        Dissenters' rights are the rights of unitholders, in certain cases, to receive "fair value" for their units, plus accrued interest, as determined by a statutorily prescribed process, which may include a judicial appraisal process. Dissenters' rights are not available in the offer. Unitholders are not required to exchange their common units in the offer.

Plans for CVR Refining after the Exchange

        Except as otherwise indicated in this prospectus/offer to exchange, neither CVR Energy nor any of its affiliates has any current plans or proposals which relate to or would result in:

•

any extraordinary transaction, such as a merger, reorganization or liquidation, involving CVR Refining or any of its subsidiaries;

42

---

Table of Contents

•

any purchase, sale or transfer of a material amount of assets of CVR Refining or any of its subsidiaries;



•

any material change in the present dividend rate or policy, or indebtedness or capitalization of CVR Refining or any of its subsidiaries;



•

any change in the present management of CVR Refining;



•

any other material change in CVR Refining's corporate structure or business;



•

the delisting of the common units from the New York Stock Exchange; or



•

the common units becoming eligible for termination of registration under the Exchange Act.

Certain Effects of the Exchange; Registration Under the Exchange Act

        Unitholders who do not exchange their common units pursuant to the offer and unitholders who otherwise retain an equity interest in CVR Refining as a result of a partial exchange of common units or proration will continue to be owners of CVR Refining. These unitholders will not realize a proportionate increase in their relative equity interest in CVR Refining. However, the exchange will increase CVR Energy's equity ownership in CVR Refining and will entitle the general partner to exercise the call right as described elsewhere in this prospectus/offer to exchange.

        Upon the completion of the exchange in accordance with its terms and conditions, CVR Refining will continue to be listed on the New York Stock Exchange and subject to the periodic reporting requirements of the Exchange Act.

        However, the consummation of the exchange will reduce the number of common units that might otherwise be traded publicly and is likely to reduce the number of unitholders. As a result, trading of a relatively small volume of the common units and limited liquidity after consummation of the exchange may have a greater impact on trading prices than would be the case prior to consummation of the exchange with an increase in price volatility. This may result in lower prices for the common units. Unitholders may not be able to sell non-exchanged common units in the future on the New York Stock Exchange or otherwise, at a net price higher than the value of the shares of CVR Energy common stock offered in the exchange. We can give no assurance as to the price at which a unitholder may be able to sell his or her common units in the future.

Conditions of the Offer

        Notwithstanding any other provision of the offer, CVR Energy is not required to accept for exchange or, subject to any applicable rules and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act (relating to CVR Energy's obligation to pay for or return tendered common units promptly after termination or expiration of the offer), exchange any common units, and may terminate or amend the offer, if, at the expiration time, the following conditions have not been satisfied or, to the extent legally permissible, waived:

CVR Energy expressly reserves the right to waive any of the conditions to the offer (to the extent legally permissible) and to make any change in the terms of or conditions to the offer.

Certain Legal Matters; Regulatory Approvals

General

        CVR Energy is not aware of any governmental license or regulatory permit that appears to be material to CVR Refining's business that might be adversely affected by CVR Energy's acquisition of CVR Refining common units pursuant to the offer or of any approval or other action by any government or governmental administrative or regulatory authority or agency, domestic or foreign, that

There can be no assurance that any of these approvals or other actions, if needed, will be obtained (with or without substantial conditions) or that if these approvals were not obtained or these other actions were not taken adverse consequences might not result to CVR Energy, CVR Refining or any of their respective subsidiaries, which could result in the failure of a condition to the offer. CVR Energy's obligation under the offer to accept for exchange and exchange the common units is subject to certain conditions. See "The Offer—Conditions of the Offer."

        If you participate in the offer, you may have a filing or other obligation pursuant to the HSR Act. By participating in the offer, you agree to comply with the HSR Act and observe all applicable waiting periods prior the consummation of the exchange with respect to your common units tendered in the offer.

Source and Amount of Funds or Other Consideration

        Based on the exchange ratio for the offer, CVR Energy estimates that if the maximum 37,154,236 common units are exchanged pursuant to the offer, a total of 23,537,209 shares of CVR Energy common stock will be issued in the exchange and if the minimum of 15,014,237 common units are exchanged pursuant to the offer, a total of 9,511,519 shares of CVR Energy common stock will be issued in the exchange.

        Unitholders who participate in the offer will not receive any fractional shares of CVR Energy common stock in the exchange or cash in lieu of fractional shares.

COMPARISON OF RIGHTS OF HOLDERS OF CVR ENERGY COMMON STOCK AND CVR REFINING COMMON UNITS

        Both CVR Energy and CVR Refining are formed under the laws of the State of Delaware and, accordingly, the rights of the equityholders of each are currently, and will continue to be, governed by Delaware law. If the exchange is completed, unitholders of CVR Refining will become CVR Energy stockholders. Ownership interests in a limited partnership are fundamentally different from ownership interests in a corporation.

        The table below summarizes the material differences between the current rights of the CVR Energy common stockholders under the CVR Energy Amended and Restated Certificate of Incorporation ("Certificate of Incorporation") and bylaws, and the rights of the CVR Refining unitholders under the certificate of limited partnership and the First Amended and Restated Agreement of Limited Partnership (the "Partnership Agreement").

        While CVR Energy believes that the summary table covers the material differences between the rights of CVR Energy and CVR Refining equityholders, the summary table may not contain all of the information that is important to you. These summaries are not intended to be a complete discussion of the respective rights of CVR Energy and CVR Refining's equityholders and are qualified in their entirety by reference to Delaware law and the various documents of CVR Energy and CVR Refining that are referred to in the summaries. You should carefully read this entire prospectus/offer to exchange and the other documents referred to in this prospectus/offer to exchange for a more complete understanding of the differences between being a common stockholder of CVR Energy and a common unitholder of CVR Refining. To find out where you can get copies of the documents references in the summary tables, see the section entitled "Where You Can Find More Information" in this prospectus/offer to exchange.

PART II

Item 20.    Indemnification of Directors and Officers.

        Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation's board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act.

        As permitted by the Delaware General Corporation Law, the Registrant's Certificate of Incorporation includes a provision that eliminates the personal liability of its directors for monetary damages for breach of fiduciary duty as a director, except for liability:

•

for any breach of the director's duty of loyalty to the Registrant or its stockholders;



•

for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;



•

under section 174 of the Delaware General Corporation Law regarding unlawful dividends and stock purchases; or



•

for any transaction for which the director derived an improper personal benefit.

        As permitted by the Delaware General Corporation Law, the Registrant's Bylaws provide that:

•

the Registrant is required to indemnify its directors and officers to the fullest extent permitted by the Delaware General Corporation Law, subject to very limited exceptions;



•

the Registrant may indemnify its other employees and agents to the fullest extent permitted by the Delaware General Corporation Law, subject to very limited exceptions;



•

the Registrant is required to advance expenses, as incurred, to its directors and officers in connection with a legal proceeding to the fullest extent permitted by the Delaware General Corporation Law, subject to very limited exceptions;



•

the Registrant may advance expenses, as incurred, to its employees and agents in connection with a legal proceeding; and



•

the rights conferred in the Bylaws are not exclusive.

        The Registrant's board of directors has approved a form of indemnification agreement for its directors and officers and expects that each of its current and future directors and officers will enter into substantially similar indemnification agreements with the Registrant to give the Registrant's directors and officers additional contractual assurances regarding the scope of the indemnification set forth in the Registrant's Certificate of Incorporation and to provide additional procedural protections. At present, there is no pending litigation or proceeding involving a director, officer or employee of the Registrant regarding which indemnification is sought, nor is the Registrant aware of any threatened litigation that may result in claims for indemnification.

        The indemnification provisions in the Registrant's Certificate of Incorporation and Bylaws and the indemnification agreements entered into between the Registrant and each of its current and future directors and officers may be sufficiently broad to permit indemnification of the Registrant's directors and officers for liabilities arising under the Securities Act.

        CVR Energy, Inc. and its subsidiaries are covered by liability insurance policies which indemnify their directors and officers against loss arising from claims by reason of their legal liability for acts as such directors, officers or trustees, subject to limitations and conditions as set forth in the policies.

        The Registration Rights Agreements between the registrant and certain investors provides for cross-indemnification in connection with registration of the registrant's common stock on behalf of such investors.

        In connection with an offering of the common stock registered hereunder, the registrant may enter into an underwriting agreement which may provide that the underwriters are obligated, under certain circumstances, to indemnify directors, officers and controlling persons of the registrant against certain liabilities, including liabilities under the Securities Act.

Item 22.    Undertakings.

(a)

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;



(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 the 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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% 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;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to

II-2

---

Table of Contents

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 to any purchaser:



(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and



(ii)

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 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 effective date, 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 effective date.



(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report, pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) 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.



(c)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or controlling persons of the registrant pursuant to the provisions described in Part II, Item 15 hereof, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue

Ladies and Gentlemen:

        We are acting as counsel to CVR Energy, Inc., a Delaware corporation (the "Company"), in connection with the preparation and filing with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), of a registration statement on Form S-4 (File No. 333-225246) (as amended or supplemented, the "Registration Statement") in connection with the exchange of up to 37,154,236 common units of CVR Refining, LP for shares of the Company's common stock at an exchange ratio of one common unit for 0.6335 shares of the Company's common stock, par value $0.01 per share (the "Shares"). This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus, other than as expressly stated herein with respect to the issuance of the Shares.

        We have examined originals or copies of such documents, corporate records and other instruments as we have deemed relevant, including, without limitation:

(i)

(ii)

the Amended and Restated Bylaws of the Company in the form filed as Exhibit 3.2 to the Registration Statement; and

certain of the resolutions of the Board of Directors of the Company.

        We have made such examination of law as we have deemed necessary to express the opinion contained herein. As to matters of fact relevant to this opinion, we have relied upon, and assumed without independent verification, the accuracy of certificates of public officials and officers of the Company. We have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified, facsimile or photostatic copies, and the authenticity of the originals of such copies.

        Based upon the foregoing, and subject to the limitations, qualifications, exceptions and assumptions expressed herein, we are of the opinion, assuming no change in the applicable law or pertinent facts, that the Shares have been duly authorized by the Company and, when issued pursuant to, and as described in, the Registration Statement and the related prospectus (as amended and supplemented through the date of issuance), will be legally issued, fully paid and non-assessable.

        This opinion is limited in all respects to the General Corporation Law of the State of Delaware, and we express no opinion as to the laws, statutes, rules or regulations of any other jurisdiction. The references and limitations to the "General Corporation Law of the State of Delaware" include all applicable Delaware statutory provisions of law and reported judicial decisions interpreting these laws.

In giving the foregoing consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
