Common Stock



        This prospectus supplement relates to the offer and sale from time to time of up to 648,386 shares of common stock, par value $0.01 per share, of Realty Income Corporation by a person or entity who may receive such shares upon redemption of Class A Common Units, or Common Units, in Realty Income, L.P. or Tau Operating Partnership, L.P., if, and to the extent that, the holder of such units elects to redeem its Common Units and we elect to issue shares of our common stock in exchange for such Common Units. The holders of these shares of our common stock are referred to herein as the "selling stockholders." Realty Income Corporation is the sole general partner of each of Realty Income, L.P and Tau Operating Partnership, L.P. The registration of the shares of common stock to which this prospectus supplement and the accompanying prospectus relate does not require the selling stockholders to sell any of its shares of common stock nor does it require us to issue any shares of common stock.

        We will not receive any proceeds from any issuance of shares of our common stock to the selling stockholders or from the sale of such shares by the applicable selling stockholder, but we have agreed to pay certain registration expenses relating to such shares of our common stock. The applicable selling stockholders from time to time may offer and sell the shares held by it directly or through agents or broker-dealers on terms to be determined at the time of sale, as described in more detail in this prospectus supplement. See "Plan of Distribution."

        Our charter contains restrictions on the ownership and transfer of our common stock intended to assist us in maintaining our status as a REIT for United States federal and/or state income tax purposes. For example, our charter restricts any person from acquiring actual or constructive ownership of more than 9.8% (in value or number of shares, whichever is more restrictive) of our outstanding shares of common stock, as more fully described in the section entitled "Restrictions on Ownership and Transfers of Stock" in the accompanying prospectus.

        We currently pay regular monthly distributions to holders of our common stock, which is listed on the New York Stock Exchange, or NYSE, under the symbol "O." On December 18, 2015, the last reported sale price of our common stock on the NYSE was $51.08 per share.

        Investing in our common stock involves risks. See "Risk Factors" beginning on page S-1 of this prospectus supplement.

        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 supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

   

The date of this prospectus supplement is December 21, 2015.

SELLING STOCKHOLDERS

        All of the 648,386 shares of common stock offered by the selling stockholders under this prospectus supplement and the accompanying prospectus represent shares of common stock that may be issued by us upon the redemption of up to 648,386 Common Units held by the selling stockholders. For every one Common Unit redeemed, the applicable selling stockholder would receive one share of common stock based on the current conversion ratio.

        On January 22, 2013, 316,965 Common Units in Tau Operating Partnership, L.P. were issued to ARC Real Estate Partners, LLC and 57 Common Units were issued to American Realty Capital Advisors, LLC, each in a private transaction exempt from the Securities Act of 1933, as amended, or the Securities Act. On June 27, 2013, 534,546 Common Units in Realty Income, L.P. were issued to SCS Fuel, LLC, a Kansas limited liability company, or SCS Fuel, in a private transaction exempt from registration under the Securities Act. On July 29, 2013, SCS Fuel distributed the Common Units to its constituent members: Larry Spitcaufsky, Trustee for the Larry S. Spitcaufsky Amended and Restated Revocable Trust dated August 23, 1995, David Selph and Lincoln Clifton.

        The following table assumes that the selling stockholders submit all of their respective Common Units for redemption and that we elect to redeem all of those Common Units for shares of our common stock instead of for cash. The table provides the name of the applicable selling stockholder, the number of shares of common stock the applicable selling stockholder owns prior to the offering and the maximum number of shares of our common stock to be offered by the applicable selling stockholder.

        We believe that the entities named in the table have sole voting and investment power with respect to all shares beneficially owned by the applicable selling stockholder. Because the applicable selling stockholder may offer, pursuant to this prospectus supplement and the accompanying prospectus, all or some portion of the common stock listed below, no estimate can be given as to the actual amount of common stock that will be held by the applicable selling stockholder upon consummation of any sales. In addition, the applicable selling stockholder listed in the table may have sold, transferred or otherwise disposed of, in transactions exempt from the registration requirements of the Securities Act, some or all of its common stock since the date as of which such information was provided to us. Information about the selling stockholders may change over time. Any changed information given to us by the selling stockholders will be set forth in prospectus supplements if and when necessary.

        Each of the selling stockholders named below and its permitted transferees, pledgees, donees or other successors may from time to time offer the shares of common stock offered by this prospectus supplement and the accompanying prospectus:

PLAN OF DISTRIBUTION

        The selling stockholders and their respective successors, which term includes their respective transferees, pledgees or donees, may sell our common stock directly to purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the applicable selling stockholder or the purchasers. These discounts, concessions or commissions as to any particular underwriter, broker-dealer or agent may be in excess of those customary in the types of transactions involved.

        The common stock may be sold in one or more transactions at:

        These sales may be effected in transactions:

        These transactions may include block transactions or crosses. Crosses are transactions in which the same broker acts as agent on both sides of the trade.

        In connection with sales of the common stock or otherwise, the applicable selling stockholder may (A) enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging positions they assume, (B) sell the common stock short and deliver the common stock to close out short positions, (C) loan or pledge the common stock to broker-dealers or other financial institutions that in turn may sell the common stock, (D) enter into option or other transactions with broker-dealers or other financial institutions that require the delivery to the broker-dealer or other financial institution of the common stock, which the broker-dealer or other financial institution may resell pursuant to this prospectus supplement and the accompanying prospectus, or (E) enter into transactions in which a broker-dealer makes purchases as a principal for resale for its own account or through other types of transactions.

        Notwithstanding anything in this section to the contrary, the common stock that may be issued upon the redemption of Common Units will only be used to cover or in settlement of any short positions in our securities if such short positions were entered into or established at a time that both (A) such shares are issued and outstanding, and (B) the resale of such shares is covered by an effective registration statement.

        The aggregate proceeds to the applicable selling stockholder from the sale of the common stock offered by it hereby will be the purchase price of our common stock less discounts and commissions, if any.

        The applicable selling stockholder and any broker-dealers or agents that participate in the sale of our common stock may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act. Profits on the sale of our common stock by the applicable selling stockholder and any discounts, commissions or concessions received by any broker-dealers or agents might be deemed to be underwriting discounts and commissions under the Securities Act. A selling stockholder who is deemed to be an "underwriter" within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act. To the extent the applicable selling stockholder may be deemed to be an "underwriter," it may be subject to statutory liabilities, including, but not limited to, Sections 11, 12 and 17 of the Securities Act.

        The selling stockholders and any other person participating in a distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder.

In addition, Regulation M may restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities with respect to the particular securities being distributed for a period of up to five business days before the distribution.

        To our knowledge, there are currently no plans, arrangements or understandings between the selling stockholders and any underwriter, broker-dealer or agent regarding the sale of our common stock by the selling stockholder.

        The selling stockholders may decide not to sell any of our common stock described in this prospectus supplement. We cannot assure holders that the selling stockholders will use this prospectus supplement to sell any or all of our common stock. Any securities covered by this prospectus supplement which qualify for sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than pursuant to this prospectus supplement. In addition, the selling stockholders may transfer, devise or gift the common stock by other means not described in this prospectus supplement.

        With respect to a particular offering of our common stock, to the extent required, an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which the prospectus accompanying this prospectus supplement is a part will be prepared and will set forth the following information:

        We will pay all of our expenses and specified expenses incurred by the selling stockholders incidental to the registration of the common stock, but each selling stockholder will be responsible for payment of commissions, concessions, fees and discounts of underwriters, broker-dealers and agents.

RATIOS OF EARNINGS FROM CONTINUING OPERATIONS TO FIXED CHARGES AND
COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

        The following table sets forth the ratios of earnings from continuing operations to fixed charges and the ratios of earnings from continuing operations to combined fixed charges and preferred stock dividends for the periods shown. The ratios of earnings from continuing operations to fixed charges were computed by dividing our earnings from continuing operations by our fixed charges. For this purpose, earnings from continuing operations consist of income from continuing operations before interest expense. Fixed charges consist of interest costs (including capitalized interest) and the amortization of debt issuance costs. In computing the ratios of earnings from continuing operations to combined fixed charges and preferred stock dividends, preferred stock dividends consist of dividends on our 7.375% Monthly Income Class D Cumulative Redeemable Preferred Stock, or Class D preferred stock, our 6.75% Monthly Income Class E Cumulative Redeemable Preferred Stock, or Class E preferred stock, and our Class F preferred stock to the extent outstanding during the periods set forth below. On May 27, 2004 and October 19, 2004, we issued 4,000,000 shares and 1,100,000 shares, respectively, of our Class D preferred stock and, on March 1, 2012, we redeemed all of our outstanding shares of Class D preferred stock. On December 7, 2006, we issued 8,800,000 shares of our Class E preferred stock. We redeemed all of the outstanding shares of our Class E preferred stock on October 24, 2014. On February 7, 2012 and April 19, 2012, we issued 14,950,000 shares and 1,400,000 shares, respectively, of our Class F preferred stock. All of these shares of Class F preferred stock are outstanding as of the date of this prospectus.

DESCRIPTION OF DEBT SECURITIES

General

        This prospectus describes certain general terms and provisions of our debt securities. When we offer to sell a particular series of debt securities, we will describe the specific terms of the series in a prospectus supplement, a pricing supplement or other offering materials. We will also indicate in the supplement or other offering materials whether the general terms and provisions described in this prospectus apply to a particular series of debt securities. Our debt securities will be our direct obligations and they may be secured or unsecured, senior or subordinated indebtedness. We may issue our debt securities under one or more indentures. Each indenture and the certificate or certificates evidencing the debt securities of each series will be in the form filed or incorporated by reference as an exhibit to the registration statement containing this prospectus, a post-effective amendment to the registration statement or a document incorporated by reference herein and may be obtained as described below under "Where You Can Find More Information." The form of indenture is subject to any amendments or supplements that may be adopted from time to time. We will enter into each indenture with a trustee and the trustee for each indenture may be the same. Each indenture will be subject to, and governed by, the Trust Indenture Act of 1939, as amended. Unless otherwise expressly stated in the applicable prospectus supplement, the debt securities will be issued under an indenture as of October 28, 1998 between us and The Bank of New York Mellon Trust Company, N.A., as successor trustee, a copy of which has been incorporated by reference as an exhibit to the registration statement containing this prospectus. Because this description of debt securities is a summary, it does not contain all the information that may be important to you and this description is subject to, and qualified in its entirety by reference to, the form of the applicable indenture and the certificate evidencing the debt securities of the applicable series. You should read the applicable indenture and the form of certificate evidencing the applicable debt securities in their entirety to assure that you have all the important information you need to make any required decisions. Unless otherwise expressly stated or the context otherwise requires, all references to the "Company," "Realty Income," "our," "we" and "us" and all similar references appearing under this caption "Description of Debt Securities" mean Realty Income Corporation excluding its subsidiaries. All other capitalized terms used, but not defined, in this section shall have the meanings set forth in the applicable indenture.

Terms

        The particular terms of any series of our debt securities will be described in a prospectus supplement or other offering materials. Additionally, any applicable modifications of or additions to the general terms of our debt securities, described in this prospectus and in the applicable indenture, will also be described in a prospectus supplement or other offering materials. Accordingly, for a description of the terms of any series of our debt securities, you must refer to both the prospectus supplement or other offering materials, if any, relating to those debt securities and the description of the debt securities set forth in this prospectus. If any particular terms of our debt securities, described in a prospectus supplement or other offering materials, differ from any of the terms described in this prospectus, then those terms as set forth in the relevant prospectus supplement or other offering materials will control.

        Except as set forth in any prospectus supplement or other offering materials, our debt securities may be issued without limit as to aggregate principal amount, in one or more series, in each case as established from time to time by our board of directors, a committee of the board of directors or as set forth in the applicable indenture or one or more supplements to that indenture. All of our debt securities of one series need not be issued at the same time, and unless otherwise provided, a series may be reopened for issuance of additional debt securities without the consent of the holders of the debt securities of that series.

8


Table of Contents

        Each indenture will provide that we may, but need not, designate more than one trustee for the indenture, each with respect to one or more series of our debt securities. Any trustee under an indenture may resign or be removed with respect to one or more series of our debt securities, and a successor trustee may be appointed to act with respect to that series. If two or more persons are acting as trustee to different series of our debt securities, each trustee shall be a trustee of a trust under the applicable indenture separate and apart from the trust administered by any other trustee and, except as otherwise indicated in this prospectus, any action taken by a trustee may be taken by that trustee with respect to, and only with respect to, the one or more series of debt securities for which it is trustee under the applicable indenture.

        This summary sets forth certain general terms and provisions of our indentures and our debt securities. For a detailed description of a specific series of debt securities, you should consult the prospectus supplement or other offering materials for that series. The prospectus supplement or other offering materials will contain the following information, to the extent applicable:

9


Table of Contents

        If the applicable prospectus supplement provides or other offering materials provide, we may issue the debt securities at a discount below their principal amount and provide for less than the entire principal amount of the debt securities to be payable upon declaration of acceleration of the maturity thereof ("Original Issue Discount Securities"). In those cases, any material United States federal income tax, accounting and other considerations applicable to Original Issue Discount Securities will be described in the applicable prospectus supplement or other offering materials.

Denominations, Interest, Registration and Transfer

        Unless otherwise described in the applicable prospectus supplement or other offering materials, the debt securities of any series will be issuable in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

        Unless otherwise described in the applicable prospectus supplement or other offering materials, we will pay the principal of (and premium, if any) and interest on any series of debt securities at the applicable trustee's corporate trust office, the address of which will be set forth in the applicable prospectus supplement or other offering materials, provided however, that unless otherwise provided in the applicable prospectus supplement or other offering materials, we may make interest payments (1) by check mailed to the address of the person entitled to the payment as that address appears in the applicable register for those debt securities, or (2) by wire transfer of funds to the person at an account maintained within the United States.

10


Table of Contents

        Subject to certain limitations imposed on debt securities issued in book-entry form, the debt securities of any series will be exchangeable for any authorized denomination of other debt securities of the same series and of a like aggregate principal amount and tenor upon surrender of those debt securities at the office of any transfer agent we designate for that purpose. In addition, subject to certain limitations imposed on debt securities issued in book-entry form, the debt securities of any series may be surrendered for conversion or registration of transfer thereof at the office of any transfer agent we designate for that purpose. Every debt security surrendered for conversion, registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer and the person requesting that transfer must provide evidence of title and identity satisfactory to us and the applicable transfer agent. No service charge will be made for any registration of transfer or exchange of any debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. We may at any time rescind the designation of any transfer agent appointed with respect to the debt securities of any series or approve a change in the location through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for that series. We may at any time designate additional transfer agents with respect to any series of debt securities.

        Neither we nor any trustee shall be required to:

No Protection in the Event of a Change of Control

        Unless we state otherwise in the applicable prospectus supplement, the debt securities of any series will not contain any provisions which may afford holders of the debt securities of such series protection in the event of a change of control of Realty Income or in the event of a highly leveraged transaction (whether or not such transaction results in a change of control), which could adversely affect holders of debt securities.

Table of Contents

Merger, Consolidation or Sale of Assets

        Each indenture will provide that we will not consolidate with, sell, lease or convey all or substantially all of our assets to, or merge with or into, any person unless:

Certain Covenants

        Existence.    Except as permitted under the heading above entitled "—Merger, Consolidation or Sale of Assets," we will be required under each indenture to do or cause to be done all things necessary to preserve and keep in full force and effect our corporate existence, all material rights (by charter, bylaws and statute) and all material franchises; provided, however, that we shall not be required to preserve any right or franchise if our board of directors determines that the preservation thereof is no longer desirable in the conduct of our business.

        Maintenance of Properties.    Each indenture will require us to cause all of our material properties used or useful in the conduct of our business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will require us to cause to be made all necessary repairs, renewals, replacements, betterments and improvements to those properties, as in our judgment may be necessary so that the business carried on in connection with those properties may be properly and advantageously conducted at all times; provided, however, that we and our Subsidiaries shall not be prevented from selling or otherwise disposing of these properties for value in the ordinary course of business.

        Insurance.    Each indenture will require us to, and to cause each of our Subsidiaries to, keep in force upon all of our and their properties and operations policies of insurance carried with responsible companies in such amounts and covering all risks as shall be customary in the industry in accordance with prevailing market conditions and availability.

        Payment of Taxes and Other Claims.    Each indenture will require us to pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed on us or any of our Subsidiaries or upon the income, profits or property of us or any of our Subsidiaries and (b) all lawful claims for labor, materials and supplies that, if unpaid, might by law become a lien upon our property or the property of any Subsidiary; provided, however, that we shall not be required to pay or discharge or cause to be paid or discharged

12


Table of Contents

any tax, assessment, charge or claim the amount, applicability or validity of which we are contesting in good faith through appropriate proceedings.

        Provisions of Financial Information.    Whether or not we are subject to Section 13 or 15(d) of the Exchange Act, we will be required by each indenture, within 15 days after each of the respective dates by which we would have been required to file annual reports, quarterly reports and other documents with the SEC if we were subject to those Sections of the Exchange Act to:

        Except as may otherwise be provided in the prospectus supplement or other offering materials relating to any series of debt securities, the term "Subsidiary," as used in any indenture means any other person of which more than 50% of (a) the equity or other ownership interests or (b) the total voting power of shares of capital stock or other ownership interests entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers, trustees or general or managing partners thereof is at the time owned by us or one or more of our Subsidiaries or a combination thereof.

        Additional Covenants.    If we make any additional covenants with respect to any series of debt securities, those covenants will be set forth in the prospectus supplement or other offering materials relating to those debt securities.

Events of Default, Notice and Waiver

        Unless otherwise provided in the applicable indenture, each indenture will provide that the following events are "events of default" for any series of debt securities issued under it:

13


Table of Contents

The term "Significant Subsidiary" as used above has the meaning ascribed to the term in Rule 1-02 of Regulation S-X promulgated under the Securities Act, as the Regulation was in effect on January 1, 1996.

        If an event of default under any indenture with respect to debt securities of any series at the time outstanding occurs and is continuing, then the applicable trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may declare the principal amount (or, if the debt securities of that series are Original Issue Discount Securities or Indexed Securities, that portion of the principal amount as may be specified in the terms thereof) of all the debt securities of that series to be due and payable immediately by written notice thereof to us (and to the applicable trustee if given by the holders). However, at any time after the declaration of acceleration with respect to debt securities of a series has been made, but before a judgment or decree for payment of the money due has been obtained by the applicable trustee, the holders of not less than a majority of the principal amount of the outstanding debt securities of that series may rescind and annul the declaration and its consequences if:

        Each indenture will also provide that the holders of not less than a majority in principal amount of the outstanding debt securities of any series may waive any past default with respect to that series and its consequences, except:

        Each indenture will require each trustee to give notice of a default under the indenture to the holders of debt securities within 90 days unless the default shall have been cured or waived, subject to certain exceptions; provided, however, that the trustee may withhold notice to the holders of any series

14


Table of Contents

of debt securities of any default with respect to that series (except a default in the payment of the principal of (or premium, if any) or interest on any debt security of that series or in the payment of any sinking fund installment in respect of any debt security of that series) if specified Responsible Officers of the trustee consider a withholding to be in those holders' interest.

        Each indenture will provide that no holders of debt securities of any series may institute any proceedings, judicial or otherwise, with respect to the indenture or for any remedy thereunder, except in the case of failure of the trustee, for 60 days, to act after it has received a written request to institute proceedings in respect of an event of default from the holders of not less than 25% in principal amount of the outstanding debt securities of that series, as well as an offer of indemnity reasonably satisfactory to it, and no direction inconsistent with the written request has been given to the trustee during the 60-day period by holders of a majority in principal amount of the outstanding debt securities of that series. This provision will not prevent, however, any holder of debt securities from instituting suit for the enforcement of payment of the principal of (and premium, if any) and interest on those debt securities at the respective due dates thereof.

        Each indenture will provide that, subject to provisions in the Trust Indenture Act of 1939 relating to its duties in case of default, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any holders of any series of the debt securities then outstanding under the indenture, unless those holders shall have offered to the trustee reasonable security or indemnity. The holders of not less than a majority in principal amount of the outstanding debt securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or of exercising any trust or power conferred upon the trustee; provided that the direction shall not conflict with any rule of law or the indenture, and provided further that the trustee may refuse to follow any direction that may involve the trustee in personal liability or that may be unduly prejudicial to the holders of debt securities of that series not joining in the direction to the trustee.

        Within 120 days after the close of each fiscal year, we will be required to deliver to the trustee a certificate, signed by one of several specified officers, stating whether or not the officer has knowledge of any default under the indenture and, if so, specifying each default and the nature and status thereof.

Modification of the Indenture

        Modifications and amendments of any indenture will be permitted with the consent of the holders of not less than a majority in principal amount of all outstanding debt securities of each series issued under the indenture affected by the modification or amendment; provided, however, that no modification or amendment may, without the consent of the holder of each debt security affected thereby:

15


Table of Contents

        The holders of a majority in aggregate principal amount of outstanding debt securities of any series may, on behalf of all holders of debt securities of that series, waive (insofar as that series is concerned) our compliance with certain restrictive covenants in the applicable indenture.

        We, along with the trustee, shall be permitted to modify and amend an indenture without the consent of any holder of debt securities for any of the following purposes:

16


Table of Contents

        Each indenture will provide that in determining whether the holders of the requisite principal amount of outstanding debt securities of a series have given any request, demand, authorization, direction, notice, consent or waiver described in the indenture or whether a quorum is present at a meeting of holders of debt securities:

        Each indenture will contain provisions for convening meetings of the holders of debt securities of a series. A meeting may be called at any time by the trustee, and also, upon our request or request of the holders of at least 10% in principal amount of the outstanding debt securities of a series, in any case upon notice given as provided in the indenture. Except for any consent or waiver that must be given by the holder of each debt security affected thereby, any resolution presented at a meeting or at an adjourned meeting duly reconvened at which a quorum is present, may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding debt securities of that series; provided, however, that, except as referred to above, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that may be made, given or taken by the holders of a specified percentage, which is less than a majority, in principal amount of the outstanding debt securities of the series may be adopted at a meeting or adjourned meeting duly reconvened at which a quorum is present by the affirmative vote of the holders of the specified percentage in principal amount of the outstanding debt securities of that series. Any resolution passed or decision taken at any meeting of holders of debt securities of any series duly held in accordance with the indenture will be binding on all holders of debt securities of that series. The persons holding or representing a majority in principal amount of the outstanding debt securities of a series shall constitute a quorum for a meeting of holders of that series; provided, however, that if any action is to be taken at a meeting with respect to a consent or waiver that may be given by the holders of not less than a specified percentage in principal amount of the outstanding debt securities of that series, the persons holding or representing the specified percentage in principal amount of the outstanding debt securities of that series will constitute a quorum.

        Notwithstanding the foregoing provisions, each indenture will provide that if any action is to be taken at a meeting of holders of debt securities of any series with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that the indenture expressly provides may be made, given or taken by the holders of that series and one or more additional series: (a) there shall be no minimum quorum requirement for the meeting and (b) the principal amount of the outstanding debt securities of all those series that are entitled to vote in favor of the request, demand, authorization, direction, notice, consent, waiver or other action shall be taken into account in determining whether the request, demand, authorization, direction, notice, consent, waiver or other action has been made, given or taken under the indenture.

Discharge, Defeasance and Covenant Defeasance

        Unless otherwise indicated in the applicable prospectus supplement or other offering materials, upon our request any indenture shall cease to be of further effect with respect to any series of debt securities issued under the indenture specified in our request (except as to certain limited provisions of the indenture which shall survive) when either (a) all debt securities of that series have been delivered to the trustee for cancellation or (b) all debt securities of that series have become due and payable or will become due and payable within one year (or are scheduled for redemption within one year) and we have irrevocably deposited with the applicable trustee, in trust, funds in the currency or currencies, currency unit or units or composite currency or currencies in which those debt securities are payable an amount sufficient to pay the entire indebtedness on those debt securities in respect of principal (and premium, if any) and interest to the date of the deposit (if those debt securities have become due and payable) or to the stated maturity or redemption date, as the case may be.

        Each indenture will provide that, unless otherwise indicated in the applicable prospectus supplement or other offering materials, we may elect either to:

in either case upon our irrevocable deposit with the applicable trustee, in trust, of an amount, in the currency or currencies, currency unit or units or composite currency or currencies in which those debt securities are payable at stated maturity, or Government Obligations (as defined below), or both, applicable to those debt securities that through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal of (and premium, if any) and interest on those debt securities, and any mandatory sinking fund or analogous payments on those debt securities, on the scheduled due dates.

        A trust may only be established if, among other things, we have delivered to the applicable trustee an opinion of counsel (as specified in the applicable indenture) to the effect that the holders of those debt securities will not recognize income, gain or loss for United States federal income tax purposes as a result of the defeasance or covenant defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance or covenant defeasance had not occurred. Additionally, in the case of defeasance, an opinion of counsel must refer to and be based on a ruling of the Internal Revenue Service (the "IRS") or a change in applicable United States federal income tax law occurring after the date of the applicable indenture. In the event of defeasance, the holders of those debt securities will thereafter be able to look only to the trust fund for payment of principal (and premium, if any) and interest.

        "Government Obligations" means securities that are (a) direct obligations of the United States of America or the government which issued the foreign currency in which the debt securities of a particular series are payable, for the payment of which its full faith and credit is pledged, or (b) obligations of a person controlled or supervised by and acting as an agency or instrumentality of the

18


Table of Contents

United States of America or the government which issued the foreign currency in which the debt securities of that series are payable, the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America or the other government, which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also include a depository receipt issued by a bank or trust company as custodian with respect to any Government Obligation or a specific payment of interest on or principal of any Government Obligation held by a custodian for the account of the holder of a depository receipt; provided, however, that (except as required by law) the custodian is not authorized to make any deduction from the amount payable to the holder of the depository receipt from any amount received by the custodian in respect of the Government Obligation or the specific payment of interest on or principal of the Government Obligation evidenced by the depository receipt.

        Unless otherwise provided in the applicable prospectus supplement or other offering materials, if after we have deposited funds and/or Government Obligations to effect defeasance or covenant defeasance with respect to debt securities of any series:

then the indebtedness represented by that debt security will be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any) and interest on that debt security as they become due out of the proceeds yielded by converting the amount so deposited in respect of that debt security into the currency, currency unit or composite currency in which the debt security becomes payable as a result of the election or Conversion Event based on the applicable market exchange rate. "Conversion Event" means the cessation of use of:

        In the event we effect a covenant defeasance with respect to any debt securities and those debt securities are declared due and payable because of the occurrence of any event of default, other than an event of default due to a breach of any of the covenants as to which there has been covenant defeasance (which covenants would no longer be applicable to those debt securities as a result of such covenant defeasance), the cash and Government Obligations on deposit with the applicable trustee may not be sufficient to pay amounts due on those debt securities at the time of the acceleration resulting from the event of default. We would, however, remain obligated to make payment of the amounts due at the time of acceleration.

        The applicable prospectus supplement or other offering materials may further describe the provisions, if any, permitting the defeasance or covenant defeasance, including any modifications to the provisions described above, with respect to the debt securities of or within a particular series.

Conversion Rights

        The terms and conditions, if any, upon which the debt securities are convertible into common stock, preferred stock or other securities offered hereby will be set forth in the applicable prospectus supplement or other offering materials relating to those debt securities. The terms will include whether

19


Table of Contents

the debt securities are convertible into common stock, preferred stock, or other securities offered hereby, and the conversion price or rate (or manner of calculation thereof), and may include, if applicable, the conversion period, provisions as to whether conversion will be at our option or the option of the holders, the events requiring an adjustment of the conversion price or rate and provisions affecting conversion in the event of the redemption of the debt securities and any restrictions on conversion, including restrictions directed at maintaining our REIT status.

Unclaimed Payments

        We will be repaid for all amounts we pay to a paying agent or a trustee for the payment of the principal of or any premium or interest on any debt security that remains unclaimed at the end of two years after the principal, premium or interest has become due and payable, and the holder of that debt security may look only to us for payment of the principal, premium or interest.

Global Securities

        The debt securities of a series may be issued in whole or in part in the form of one or more global securities (the "Global Securities") that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement or other offering materials relating to that series. Global Securities may be issued in either registered or bearer form and in either temporary or permanent form. The specific terms of the depositary arrangement with respect to a series of debt securities will be described in the applicable prospectus supplement or other offering materials relating to that series.

Terms

        Subject to the preferential rights of any other class or series of stock and to the provisions of our charter regarding the restrictions on ownership and transfer of stock, holders of our common stock are entitled to receive dividends when, as and if authorized by our board of directors and declared by us out of assets legally available therefor. The terms of our outstanding Class F preferred stock provide in general that if we fail to declare and pay or declare and set apart for payment full cumulative dividends on the preferred stock of that class for all past dividend periods and the then current dividend period, no dividends or distributions on our common stock (other than dividends payable in shares of common stock or other shares of our capital stock ranking junior to the outstanding preferred stock of that class) may be declared or paid nor may we purchase or otherwise acquire any of our common stock (except by conversion into or exchange for other capital stock of ours ranking junior to the outstanding preferred stock of that class and except for purchases or acquisitions of our stock for the purpose of preserving our status as a REIT for United States federal and/or state income tax purposes). If we were to experience liquidation, dissolution or winding up, holders of our common stock would be entitled to share equally and ratably in any assets available for distribution to them, after payment or adequate provision for payment of our debts and other liabilities and the preferential amounts owing with respect to our outstanding preferred stock. The terms of our outstanding Class F preferred stock provide in general that, in the event of our liquidation, dissolution or winding up, the holders of that preferred stock will be entitled to receive, out of assets legally available for distribution to our stockholders, a liquidating distribution of $25 per share, plus accrued and unpaid dividends, before any distribution or payment may be made to the holders of our common stock. The terms of any additional preferred stock we may issue in the future may also provide for restrictions or prohibitions on the payment of dividends on, and the purchase of, our common stock and may also provide for holders of that preferred stock to receive preferential distributions in the event of our liquidation, dissolution or winding up before any payments may be made on our common stock. For additional information, see "General Description of Preferred Stock—Dividends" and "General Description of Preferred Stock—Liquidation Preference" in this prospectus, the articles supplementary designating the terms of our outstanding Class F preferred stock which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part, the description of our Class F preferred stock contained in our Registration Statement on Form 8-A, including any subsequently filed amendments and reports

filed for the purpose of updating such description, referred to under "Incorporation by Reference" below, and, if applicable, the articles supplementary designating the terms of any class or series of preferred stock we may subsequently issue, which will be filed or incorporated by reference as an exhibit to the registration statement of which this prospectus is a part or to a document incorporated or deemed to be incorporated by reference in this prospectus, and the description of any such subsequently issued class or series of our preferred stock contained in the applicable Registration Statement on Form 8-A, including any subsequently filed amendments and reports filed for purposes of updating such descriptions, which may be obtained as described below under "Where You Can Find More Information" and "Incorporation by Reference".

        Subject to the provisions of our charter regarding the restrictions on ownership and transfer of stock (see "Restrictions on Ownership and Transfers of Stock" below), each outstanding share of our common stock entitles the holder to one vote on all matters submitted to a vote of stockholders, including the election of directors (other than any directors to be elected exclusively by holders of our outstanding preferred stock) and, except as provided with respect to any other class or series of stock, the holders of shares of our common stock will possess the exclusive voting power. For information regarding certain voting rights of our preferred stock, see "General Description of Preferred Stock—Voting Rights" in this prospectus, the articles supplementary designating the terms of our outstanding Class F preferred stock incorporated by reference as exhibits to the registration statement of which this prospectus is a part, the description of our Class F preferred stock contained in our Registration Statement on Form 8-A, including any subsequently filed amendments and reports filed for the purpose of updating such description, referred to under "Incorporation by Reference" below, and, if applicable, the articles supplementary designating the terms of any class or series of preferred stock we may subsequently issue, which will be filed or incorporated by reference as an exhibit to the registration statement of which this prospectus is a part or to a document incorporated or deemed to be incorporated by reference in this prospectus, and the description of any such subsequently issued class or series of our preferred stock contained in the applicable Registration Statement on Form 8-A, including any subsequently filed amendments and reports filed for purposes of updating such descriptions, which may be obtained as described below under "Where You Can Find More Information" and "Incorporation by Reference".

        Holders of our common stock do not have cumulative voting rights in the election of directors, which means that holders of more than 50% of all the shares of our common stock voting for the election of directors can elect all the directors standing for election at the time if they choose to do so, and the holders of the remaining shares cannot elect any directors. All of our directors currently serve a one year term. Holders of shares of common stock do not have preemptive rights, which means they have no right under the charter, bylaws, or Maryland law to acquire any additional shares of common stock that may be issued by us at a subsequent date. Holders of shares of common stock have no preference, conversion, exchange, sinking fund or redemption rights. Under Maryland law, stockholders generally are not liable for the corporation's debts or obligations.

        Under the Maryland General Corporation Law, or MGCL, a Maryland corporation generally cannot dissolve, amend its charter, merge, convert into another entity, sell all or substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business unless approved by the affirmative vote of stockholders holding at least two-thirds of the shares entitled to vote on the matter unless a lesser percentage (but not less than a majority of all of the votes entitled to be cast on the matter) is set forth in the corporation's charter. Our charter provides that any such action shall be effective if approved by the affirmative vote of holders of shares entitled to cast a majority of all the votes entitled to be cast on the matter. Because the term "substantially all" of a company's assets is not defined in the MGCL, it is subject to Maryland common law and to judicial interpretation and review in the context of the unique facts and circumstances of

22


Table of Contents

any particular transaction. Accordingly, there may be uncertainty as to whether a sale of "substantially all" of our assets has taken place within the meaning of the MGCL provisions described above.

        Our charter authorizes our board of directors to classify and reclassify any unissued shares of our common stock or preferred stock into other classes or series of stock and to establish the number of shares in each class or series and to set the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption for each such class or series. Thus, the board could cause the issuance of shares of preferred stock with dividend rights, rights to distributions in the event of our liquidation, dissolution or winding up, voting rights or other rights that could adversely affect the rights of holders of our common stock or delay or prevent a tender offer or change of control of our company that might involve a premium price for holders of our common stock or otherwise be in their best interests, any of which could adversely affect the market price of our common stock. For additional information, see "General Description of Preferred Stock" and "Certain Provisions of Maryland Law and of our Charter and Bylaws—Effect of Certain Provisions of Maryland Law and our Charter and Bylaws."

Restrictions on Ownership

        For us to qualify as a REIT under the Internal Revenue Code of 1986, as amended, or the Code, not more than 50% in value of our outstanding stock may be owned, actually or constructively, by or for five or fewer individuals (defined in the Code to include certain entities) during the last half of a taxable year. To assist us in meeting this requirement and certain other requirements relating to our tax status as a REIT, our charter contains provisions intended to limit the actual, beneficial or constructive ownership by a single person or entity of our outstanding common stock. See "Restrictions on Ownership and Transfers of Stock" below.

Transfer Agent

        The registrar and transfer agent for our common stock is Wells Fargo Bank, N.A.

GENERAL DESCRIPTION OF PREFERRED STOCK

        We are authorized to issue 69,900,000 shares of preferred stock, $0.01 par value per share. As of December 18, 2015, we had outstanding 16,350,000 shares of our Class F preferred stock. For a description of some of the terms of our outstanding Class F preferred stock, see the articles supplementary designating the terms of such class of preferred stock which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part and the description of such class of preferred stock contained in our Registration Statement on Form 8-A, including any subsequently filed amendments and reports filed for the purpose of updating such description, referred to under "Incorporation by Reference" below. For a description of some of the terms of any other class or series of preferred stock we may issue in the future, see the articles supplementary designating the terms of such class or series of preferred stock, which will be filed or incorporated by reference as an exhibit to the registration statement of which this prospectus is a part or a document incorporated or deemed to be incorporated by reference in this prospectus, and the description of such class or series of preferred stock contained in the applicable Registration Statement on Form 8-A, including any subsequently filed amendments and reports filed for the purpose of updating such description, which may be obtained as described below under "Where You Can Find More Information" and "Incorporation by Reference."

General

        The following description of our preferred stock sets forth certain general terms and provisions of our preferred stock to which any prospectus supplement or other offering materials may relate. The statements below describing our preferred stock are not complete, do not contain all of the information that may be important to you and are in all respects subject to and qualified in their entirety by reference to the applicable provisions of our charter (including the applicable articles supplementary designating the terms of a class or series of preferred stock) and our bylaws, copies of which have been or will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part or a document incorporated or deemed to be incorporated by reference herein and may be obtained as described below under "Where You Can Find More Information." You should review our charter and bylaws and the articles supplementary designating the terms of the applicable class or series of our preferred stock carefully before you invest. As used under this caption "General Description of Preferred Stock," references to "Realty Income," "our," "we" and "us," and all similar references, mean Realty Income Corporation excluding its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

        Our charter authorizes our board of directors to classify any unissued shares of preferred stock and to reclassify any previously classified but unissued shares of any class or series. Prior to the issuance of shares of each series or class, our board is required by the MGCL and our charter to determine the number of shares of such class or series and to set, subject to the provisions of our charter regarding the restrictions on ownership and transfer of stock, the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each such series or class. Thus, the board could authorize the issuance of shares of preferred stock with dividend rights, rights to distributions in the event of our liquidation, dissolution or winding up, voting rights or other rights that could adversely affect the rights of holders of our common stock or which could have the effect of delaying or preventing a tender offer or a change in control of us that might involve a premium price for holders of our common stock or otherwise be in their best interest, any of which could adversely affect the market price of our common stock. For additional information, see "Certain Provisions of Maryland Law and of our Charter and Bylaws—Effect of Certain Provisions of Maryland Law and our Charter and Bylaws." The following discussion is applicable to any additional preferred stock that we may issue.

        You should refer to the prospectus supplement or other offering materials relating to the preferred stock offered thereby for specific terms of and other information concerning the preferred stock, including:

Rank

        Unless otherwise specified in the applicable prospectus supplement or other offering materials, the preferred stock of any series or class will rank, with respect to the payment of dividends and the distribution of assets in the event of our liquidation, dissolution or winding up:

25


Table of Contents

For these purposes, the term "equity securities" does not include convertible debt securities.

Dividends

        Holders of shares of our preferred stock of each series or class shall be entitled to receive, when, as and if authorized by our board of directors and declared by us, out of our assets legally available for payment, cash dividends at rates and on dates as will be set forth in the applicable prospectus supplement or other offering materials. Each dividend shall be payable to holders of record as they appear on our stock transfer books on the record dates as shall be fixed by our board of directors.

        Dividends on any series or class of our preferred stock may be cumulative or noncumulative, as provided in the applicable prospectus supplement or other offering materials. Dividends, if cumulative, will be cumulative from and after the date set forth in the applicable prospectus supplement or other offering materials. If our board of directors fails to authorize a dividend payable on a dividend payment date on any series or class of preferred stock for which dividends are noncumulative, then the holders of such series or class of preferred stock will have no right to receive a dividend in respect of the dividend period ending on that dividend payment date, and we will have no obligation to pay the dividend accrued for such period, whether or not dividends on such series or class are declared or paid for any future period.

        If any shares of preferred stock of any series or class are outstanding, no full dividends shall be declared or paid or set apart for payment on the preferred stock of any other series or class ranking, as to dividends, on a parity with or junior to the preferred stock of that series or class for any period unless:

        When dividends are not paid in full (or a sum sufficient for the full payment is not set apart) upon the shares of preferred stock of any series or class and the shares of any other series or class of preferred stock ranking on a parity as to dividends with the preferred stock of that series or class, then all dividends declared on shares of preferred stock of that series or class and any other series or class of preferred stock ranking on a parity as to dividends with that preferred stock shall be declared pro rata so that the amount of dividends declared per share on the preferred stock of that series or class and such other series or class of preferred stock shall in all cases bear to each other the same ratio that accrued and unpaid dividends per share on the shares of preferred stock of such series or class (which shall not include any accumulation in respect of unpaid dividends for prior dividend periods if such preferred stock does not have a cumulative dividend) and such other series or class of preferred stock (which, in the case of any such other series or class of preferred stock, shall not include any accumulation in respect of unpaid dividends for prior dividend periods if such other series or class of preferred stock does not have a cumulative dividend) bear to each other. No interest, or sum of money

26


Table of Contents

in lieu of interest, shall be payable in respect of any dividend payment or payments on preferred stock of such series or class that may be in arrears.

        Except as provided in the immediately preceding paragraph, unless:

then no dividends (other than in the common stock or other stock of ours ranking junior to the preferred stock of that series or class as to dividends and as to the distribution of assets upon liquidation, dissolution or winding up of us) shall be declared or paid or set aside for payment nor shall any other distribution be declared or made on the common stock or any other class or series of stock of ours ranking junior to or on a parity with the preferred stock of that series or class as to dividends or as to the distribution of assets upon liquidation, dissolution or winding up of us, nor shall any shares of the common stock or any other stock of ours ranking junior to or on a parity with the preferred stock of that series or class as to dividends or as to the distribution of assets upon liquidation, dissolution or winding up of us be redeemed, purchased or otherwise acquired for any consideration (or any amounts be paid to or made available for a sinking fund for the redemption of any shares of any such stock) by us (except by conversion into or exchange for other stock of ours ranking junior to the preferred stock of that series or class as to dividends and as to the distribution of assets upon liquidation, dissolution or winding up of us); provided, however, that the foregoing shall not prevent the purchase or acquisition of shares of our stock to preserve our status as a REIT for federal and/or state income tax purposes.

        Any dividend payment made on shares of a series or class of preferred stock shall first be credited against the earliest accrued but unpaid dividend due with respect to shares of that series or class that remains payable.

Redemption

        If the applicable prospectus supplement or other offering material so states, the shares of preferred stock will be subject to mandatory redemption or redemption at our option, as a whole or in part, in each case on the terms, at the times and at the redemption prices set forth in that prospectus supplement or other offering material.

        The prospectus supplement or other offering materials relating to a series or class of preferred stock that is subject to mandatory redemption will specify the number of shares of that preferred stock that shall be redeemed by us in each year commencing after a date to be specified, at a redemption price per share to be specified, together with an amount equal to all accumulated and unpaid dividends thereon (which shall not, if such preferred stock does not have a cumulative dividend, include any accumulation in respect of unpaid dividends for prior dividend periods) to the date of redemption. The redemption price may be payable in cash or other property, as specified in the applicable prospectus supplement or other offering materials. If the redemption price for preferred stock of any series or class is payable only from the net proceeds of the issuance of our stock, the terms of that preferred stock may provide that, if no such stock shall have been issued or, to the extent the net proceeds from any issuance are insufficient to pay in full the aggregate redemption price then due, that preferred

27


Table of Contents

stock shall automatically and mandatorily be converted into shares of our applicable stock pursuant to conversion provisions specified in the applicable prospectus supplement or other offering materials.

        Notwithstanding the foregoing, unless:

then no shares of that series or class of preferred stock shall be redeemed unless all outstanding shares of preferred stock of that series or class are simultaneously redeemed; provided, however, that the foregoing shall not prevent the purchase or acquisition of shares of preferred stock of that series or class to preserve our REIT status for federal and/or state income tax purposes or pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of preferred stock of that series or class.

        In addition, unless:

we shall not purchase or otherwise acquire directly or indirectly any shares of preferred stock of such series or class (except by conversion into or exchange for stock of ours ranking junior to the preferred stock of that series or class as to dividends and upon the distribution of assets upon liquidation, dissolution and winding up of us); provided, however, that the foregoing shall not prevent the purchase or acquisition of shares of preferred stock of such series or class to preserve our REIT status for federal and/or state income tax purposes or pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of preferred stock of that series or class.

        If fewer than all the outstanding shares of preferred stock of any series or class are to be redeemed, the number of shares to be redeemed will be determined by us and the shares to be redeemed shall be selected pro rata (as nearly as may be practicable without creating fractional shares) or by any other equitable method determined by us that will not result in the automatic transfer of any shares of preferred stock of such series or class to a trust in order to avoid adversely affecting our REIT status.

        Notice of redemption will be mailed at least 30, but not more than 60, days before the redemption date to each holder of record of a share of preferred stock of any series or class to be redeemed at the address shown on our stock transfer books. Each notice shall state:

28


Table of Contents

        If fewer than all the shares of preferred stock of any series or class are to be redeemed, the notice mailed to each holder shall also specify the number of shares of preferred stock to be redeemed from such holder and, upon redemption, a new certificate shall be issued representing the unredeemed shares without cost to the holder thereof. If notice of redemption of any shares of preferred stock has been given and if the funds necessary for the redemption have been irrevocably set aside by us in trust for the benefit of the holders of the shares of preferred stock so called for redemption, then from and after the redemption date dividends will cease to accrue on such shares of preferred stock, such shares of preferred stock shall no longer be deemed outstanding and all rights of the holders of such shares will terminate, except the right to receive the redemption price plus accrued and unpaid dividends, if any.

        Notwithstanding the foregoing and except as otherwise may be required by law, the persons who were holders of record of shares of any class or series of preferred stock at the close of business on a record date for the payment of dividends will be entitled to receive the dividend payable on the corresponding dividend payment date notwithstanding the redemption of those shares after the record date and on or prior to the dividend payment date or our default in the payment of the dividend due on that dividend payment date. In that case, the amount payable on the redemption of those shares of preferred stock will not include that dividend. Except as provided in the preceding sentence and except to the extent that accrued and unpaid dividends are payable as part of the redemption price, we will make no payment or allowance for unpaid dividends, whether or not in arrears, on shares of preferred stock called for redemption.

        Subject to applicable law and the limitation on purchases when dividends on a series or class of preferred stock are in arrears, we may, at any time and from time to time, purchase any shares of such series or class of preferred stock in the open market, by tender or by private agreement.

Liquidation Preference

        Upon any voluntary or involuntary liquidation, dissolution, or winding up of our company, the holders of each series or class of our preferred stock shall be entitled to receive, out of our assets legally available for distribution to our stockholders, a liquidating distribution in the amount of the liquidation preference per share (set forth in the applicable prospectus supplement or other offering materials) applicable to that class or series, plus an amount equal to any accrued and unpaid dividends to the date of payment (which shall not include any accumulation in respect of unpaid dividends for prior dividend periods if the preferred stock of such class or series does not have a cumulative dividend), before any distribution or payment will be made to the holders of common stock or any other series or class of stock ranking junior to that series or class of preferred stock in the distribution of assets upon any liquidation, dissolution or winding up of our company, but subject to the preferential rights of the holders of shares of any class or series of our stock ranking senior to such series or class of preferred stock with respect to the distribution of assets upon liquidation, dissolution or winding up. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of that series or class of preferred stock, as such, will have no right or claim to any of our remaining assets. If, upon any such voluntary or involuntary liquidation, dissolution or winding up, the assets legally available therefor are insufficient to pay the full amount of the liquidating

29


Table of Contents

distributions payable on all outstanding shares of any series or class of preferred stock and the full amount of the liquidating distributions payable on all shares of any other classes or series of our stock ranking on a parity with that series or class of preferred stock in the distribution of assets upon liquidation, dissolution or winding up, then the holders of that series or class of preferred stock and all other such classes or series of stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled.

        If liquidating distributions shall have been made in full to all holders of any series or class of preferred stock, our remaining assets will be distributed among the holders of any other classes or series of stock ranking junior to that series or class of preferred stock upon liquidation, dissolution or winding up, according to their respective rights and preferences. For those purposes, neither the consolidation or merger of us with or into any other entity, nor the sale, lease, transfer or conveyance of all or substantially all of our property or business, shall be deemed to constitute a liquidation, dissolution or winding up of us.

Voting Rights

        Except as may be set forth in the applicable prospectus supplement or other offering materials, whenever dividends on any shares of preferred stock of any series or class shall be in arrears for 18 or more monthly dividend periods, whether or not consecutive, the number of directors constituting our board of directors will be automatically increased by two (if not already increased by two by reason of the election of directors by the holders of any other class or series of our preferred stock upon which like voting rights have been conferred and are exercisable and with which the preferred stock of such class or series is entitled to vote as a class with respect to the election of those two directors, which may include our Class F preferred stock, if then outstanding), and the holders of such series or class of preferred stock (voting separately as a class with all other classes or series of preferred stock upon which like voting rights have been conferred and are exercisable and which are entitled to vote as a class with such class or series of preferred stock in the election of those two directors) will be entitled to vote for the election of such two additional directors to our board of directors at a special meeting called by us at the request of the holders of record of at least 10% of the outstanding shares of such class or series of preferred stock or by the holders of any other class or series of preferred stock upon which like voting rights have been conferred and are exercisable and which are entitled to vote as a class with that class or series of preferred stock in the election of those two directors (unless the request is received less than 90 days before the date fixed for the next annual or special meeting of stockholders, in which case such vote will be held at the earlier of the next annual or special meeting of stockholders), and at each subsequent annual meeting until all dividends accumulated on the shares of preferred stock of that class or series for all past dividend periods and the then current dividend period shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment. In that case, the right of the holders of the preferred stock of that class or series to elect those two directors will cease and (unless there are one or more other classes or series of our preferred stock upon which like voting rights have been conferred and are exercisable) the term of office of the two directors will automatically terminate and the number of directors constituting the board of directors will be reduced accordingly. If a special meeting is not called by us within 30 days after a request from the holders of the preferred stock of that class or series as described above, then the holders of record of at least 10% of the outstanding shares of that class or series of preferred stock may designate a holder to call the meeting at our expense.

        So long as any shares of any class or series of preferred stock remain outstanding, we shall not, without the consent or the affirmative vote of the holders of at least two-thirds of the shares of such

30


Table of Contents

class or series of preferred stock outstanding at the time, given in person or by proxy, either in writing or at a meeting (with such series or class of preferred stock voting separately as a class):

provided that any amendment to our charter to authorize any increase in the number of authorized shares of preferred stock or common stock or the creation or issuance of any other class or series of preferred stock or any increase in the number of authorized or outstanding shares of such series or class or any other series or class of preferred stock, in each case ranking on a parity with or junior to the preferred stock of such series or class with respect to payment of dividends and the distribution of assets upon liquidation, dissolution and winding up, shall not be deemed to materially and adversely affect any right, preference, privilege or voting power of that series or class of preferred stock.

        The foregoing voting provisions will not apply if, at or prior to the time when the act, with respect to which the vote would otherwise be required, shall be effected, all outstanding shares of such series or class of preferred stock shall have been redeemed or called for redemption upon proper notice and sufficient funds shall have been irrevocably deposited in trust to effect the redemption.

Conversion Rights

        The terms and conditions, if any, upon which shares of any series or class of preferred stock are convertible into shares of common stock or other securities will be set forth in the applicable prospectus supplement or other offering materials. The terms will include the conversion price or rate (or the manner of calculation thereof) and, if applicable, the conversion period, provisions as to whether conversion will be at the option of the holders of the preferred stock or us, the events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption of the preferred stock.

Restrictions on Ownership

        For us to qualify as a REIT under the Code, not more than 50% in value of our outstanding capital stock may be owned, actually or constructively, by or for five or fewer individuals (defined in the Code to include certain entities) during the last half of a taxable year. To assist us in meeting this requirement and certain other requirements relating to our tax status as a REIT, the articles supplementary establishing any class or series of preferred stock may contain provisions, which will be described in the applicable prospectus supplement or other offering materials, intended to limit the

31


Table of Contents

actual, beneficial or constructive ownership by a single person or entity of our outstanding preferred stock.

Transfer Agent

        The transfer agent and registrar for any series or class of preferred stock will be set forth in the applicable prospectus supplement or other offering materials.

DESCRIPTION OF DEPOSITARY SHARES

        We may issue depositary shares, each of which will represent a fractional interest in a share of a particular class or series of our preferred stock, as specified in the applicable prospectus supplement. Shares of a class or series of preferred stock represented by depositary shares will be deposited under a separate deposit agreement that we will enter into with a bank or trust company named therein, as depositary, which depositary receipts will evidence the depositary shares. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fractional interest in a share of a particular class or series of preferred stock represented by the depositary shares evidenced by that depositary receipt, to the rights and preferences of, and will be subject to the limitations and restrictions on, the class or series of preferred stock represented by those depositary shares (including, if applicable, dividend, voting, conversion, redemption and liquidation rights).

        Some of the particular terms of the depositary shares offered by the applicable prospectus supplement, as well as some of the terms of the related deposit agreement, will be described in the prospectus supplement, which may also include a discussion of certain U.S. federal income tax consequences.

        Copies of the applicable form of deposit agreement and depositary receipt will be filed or incorporated by reference as exhibits to the registration statement of which this prospectus is a part or to a document incorporated or deemed to be incorporated by reference herein and may be obtained as described below under "Where You Can Find More Information." The statements in this prospectus relating to any deposit agreement, the depositary receipts to be issued thereunder and the related depositary shares are summaries of certain anticipated provisions thereof and do not purport to be complete and are subject to, and qualified in their entirety by reference to, all of the provisions of the applicable deposit agreement and related depositary receipts. Accordingly, you should read the form of deposit agreement and depositary receipt in their entirety before making an investment decision.

DESCRIPTION OF WARRANTS

        We may issue warrants for the purchase of our debt securities, common stock, preferred stock or depositary shares and may issue warrants independently or together with our debt securities, common stock, preferred stock or depositary shares or attached to or as units with such securities. We will issue each series of warrants under a separate warrant agreement between us and a bank or trust company as warrant agent, as specified in the applicable prospectus supplement.

        The applicable prospectus supplement will describe the terms of the warrants in respect of which that prospectus supplement is delivered, including, where applicable, the following:

RESTRICTIONS ON OWNERSHIP AND TRANSFERS OF STOCK

Internal Revenue Code Requirements

        To maintain our REIT status under the Code, no more than 50% in value of our outstanding shares of stock may be owned, actually or constructively, by or for five or fewer individuals (as defined in the Code to include certain entities) during the last half of a taxable year. In addition, if we, or an owner of 10% or more of our stock, actually or constructively owns 10% or more of a tenant of ours (or a tenant of any partnership or limited liability company that is treated as a partnership for federal income tax purposes in which we are a partner or member), the rent received by us (either directly or through one or more subsidiaries) from that tenant will not be qualifying income for purposes of the REIT gross income tests of the Code. A REIT's stock must also be beneficially owned by 100 or more persons during at least 335 days of a taxable year of twelve months or during a proportionate part of a shorter taxable year.

Transfer Restrictions in Charter

        Because we expect to continue to qualify as a REIT, our charter contains restrictions on the ownership and transfer of our common stock which, among other purposes, are intended to assist us in complying with applicable Code requirements. Our charter provides that, subject to certain specified exceptions, no person or entity may own, or be deemed to own by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% (by number or value, whichever is more restrictive) of our outstanding shares of common stock. We refer to these restrictions as the "ownership limit." The constructive ownership rules of the Code are complex, and may cause shares of common stock owned actually or constructively by a group of related individuals and/or entities to be constructively owned by one individual or entity. As a result, the acquisition of less than 9.8% of the shares of common stock (or the acquisition of an interest in an entity that owns, actually or constructively, common stock) by an individual or entity, could nevertheless cause that individual or entity, or another individual or entity, to constructively own more than 9.8% of our outstanding common stock and thus violate the ownership limit, or any other limit as provided in our charter or as otherwise permitted by our board of directors. Our board of directors may, but in no event is required to, exempt from the ownership limit a particular stockholder if it determines that such ownership will not jeopardize our status as a REIT. As a condition of such exemption, the board of directors may require a ruling from the Internal Revenue Service or an opinion of counsel satisfactory to it and/or undertakings or representations from the applicant with respect to preserving our REIT status.

        Our charter further prohibits (1) any person from actually or constructively owning shares of our common stock that would result in our being "closely held" under Section 856(h) of the Code or otherwise cause us to fail to qualify as a REIT, and (2) any person from transferring shares of our common stock if such transfer would result in shares of our capital stock being beneficially owned by fewer than 100 persons (determined without reference to any rules of attribution).

        Any person who acquires or attempts to acquire actual or constructive ownership of shares of our common stock that would violate any of the foregoing restrictions on transferability and ownership is required to give notice to us immediately and provide us with such other information as we may request in order to determine the effect of such transfer on our status as a REIT. The foregoing restrictions on transferability and ownership will not apply if our board of directors determines that it is no longer in our best interest to attempt to qualify, or to continue to qualify, as a REIT and such determination is approved by the holders of two-thirds of all shares entitled to vote on the matter, as required by our charter. Except as otherwise described above, any change in the ownership limit would require an amendment to the charter.

        Our outstanding preferred stock is subject to transfer restrictions similar to those described under this caption "Restrictions on Ownership and Transfers of Stock," and we anticipate that any class or

35


Table of Contents

series of preferred stock that we issue in the future will also be subject to similar restrictions. The restrictions on transfer applicable to any class or series of preferred stock we issue will be described in the applicable prospectus supplement or other offering materials.

Effect of Violation of Transfer Provisions

        According to our charter, if any purported transfer of common stock or any other event would result in any person violating the ownership limit or such other limit as provided in the charter, or as otherwise permitted by our board of directors, or result in our being "closely held" under Section 856(h) of the Code, or otherwise cause us to fail to qualify as a REIT, then the number of shares that would otherwise cause such violation or result will be transferred automatically to a trust, the beneficiary of which will be a qualified charitable organization selected by us. Such automatic transfer shall be deemed to be effective as of the close of business on the business day prior to the date of such violative transfer.

        Within 20 days of receiving notice from us of the transfer of shares to the trust, the trustee of the trust (who shall be designated by us and be unaffiliated with us and any prohibited transferee or prohibited owner) will be required to sell such shares to a person or entity who could own the shares without violating the ownership limit, or any other limit as provided in our charter or as otherwise permitted by our board of directors, and distribute to the prohibited transferee or prohibited owner, as applicable, an amount equal to the lesser of the price paid by the prohibited transferee or prohibited owner for such shares or the net sales proceeds received by the trust for such shares. In the case of any event other than a transfer, or in the case of a transfer for no consideration (such as a gift), the trustee will be required to sell such shares to a qualified person or entity and distribute to the prohibited owner an amount equal to the lesser of the market price (determined as provided in our charter) of such shares as of the date of the event resulting in the transfer or the net sales proceeds received by the trust for such shares. In either case, any proceeds in excess of the amount distributable to the prohibited transferee or prohibited owner, as applicable, will be distributed to the beneficiary. Prior to a sale of any such shares by the trust, the trustee will be entitled to receive, in trust for the beneficiary, all dividends and other distributions paid by us with respect to such shares, and also will be entitled to exercise all voting rights with respect to such shares.

        Subject to Maryland law, effective as of the date that such shares have been transferred to the trust, the trustee shall have the authority (at the trustee's sole discretion) (1) to rescind as void any vote cast by a prohibited transferee or prohibited owner, as applicable, prior to the discovery by us that such shares have been transferred to the trust and (2) to recast such vote in accordance with the desires of the trustee acting for the benefit of the beneficiary. However, if we have already taken irreversible corporate action, then the trustee shall not have the authority to rescind and recast that vote. Any dividend or other distribution paid to the prohibited transferee or prohibited owner (prior to the discovery by us that such shares had been automatically transferred to a trust as described above) will be required to be repaid to the trustee upon demand for distribution to the beneficiary. In the event that the transfer to the trust as described above is not automatically effective (for any reason) to prevent violation of the ownership limit or any other limit as provided in our charter or as otherwise permitted by our board of directors, then our charter provides that the transfer of such shares will be void.

        In addition, shares of our common stock held in the trust shall be deemed to have been offered for sale to us, or our designee, at a price per share equal to the lesser of (1) the price per share in the transaction that resulted in such transfer to the trust (or, in the case of a devise or gift, the market price at the time of such devise or gift) and (2) the market price on the date we or our designee, accepts such offer. We shall have the right to accept such offer until the trustee has sold the shares of common stock held in the trust. Upon such a sale to us, the interest of the beneficiary in the shares

36


Table of Contents

sold shall terminate and the trustee shall distribute the net proceeds of the sale to the prohibited transferee or prohibited owner.

        If any purported transfer of shares of common stock would cause us to be beneficially owned by fewer than 100 persons, such transfer will be null and void in its entirety and the intended transferee will acquire no rights to the stock.

        All certificates representing shares of our common stock will bear a legend referring to the restrictions described above. The foregoing ownership limitations could delay, defer or prevent a transaction or a change in control of Realty Income that might involve a premium price for the common stock or otherwise be in the best interest of stockholders.

        As set forth in the Treasury Regulations, every owner of a specified percentage (or more) of the outstanding shares of our stock (including both common stock and preferred stock) must file a completed questionnaire with us containing information regarding their ownership of such shares. Under current Treasury Regulations, the percentage will be set between 0.5% and 5.0%, depending upon the number of record holders of our shares of stock. Under our charter, each common stockholder shall upon demand be required to disclose to us in writing such information as we may request in order to determine the effect, if any, of such common stockholder's actual and constructive ownership of common stock on our status as a REIT and to ensure compliance with the ownership limit, or any other limit as provided in our charter or as otherwise permitted by our board of directors.

CERTAIN PROVISIONS OF MARYLAND LAW AND OF OUR CHARTER AND BYLAWS

        The following summary of certain provisions of Maryland law and of our charter and bylaws does not purport to be complete and is subject to and qualified in its entirety by reference to our charter and bylaws, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part, and to the MGCL. See "Where You Can Find More Information."

Election and Removal of Directors

        Our charter and bylaws provide that our board of directors may establish the number of directors of our company as long as the number is not fewer than the minimum number required under the MGCL, which is one, nor, unless our bylaws are amended, more than 15.

        Pursuant to our charter, each of our directors is elected by our stockholders to serve until the next annual meeting and until his or her successor is duly elected and qualifies.

        Pursuant to our bylaws, directors in uncontested elections are elected upon the affirmative vote of a majority of the total votes cast for and against such nominee at a duly called meeting of stockholders, and directors in contested elections are elected by a plurality of all of the votes cast. In both uncontested and contested elections, holders of shares of our common stock have no right to cumulative voting in the election of directors. Consequently, at each annual meeting of stockholders, the holders of a majority of the shares of our common stock will be able to elect all of our directors.

        Under the MGCL and our bylaws, except as otherwise provided in the terms of any class or series of our stock, vacancies on our board of directors created by any reason other than an increase in the number of directors may be filled by a majority of the remaining directors, even if the remaining directors do not constitute a quorum, and any vacancy in the number of directors created by an increase in the number of directors may be filled by a majority vote of the entire board. Any individual elected to fill a vacancy will serve for until the next annual meeting of stockholders and until his or her successor is duly elected and qualifies.

        Our charter provides that, subject to the rights of holders of shares of one or more classes or series of preferred stock to elect or remove one or more directors, a director may be removed only for cause and by the affirmative vote of stockholders entitled to cast a majority of the votes entitled to be cast generally in the election of directors.

        The articles supplementary designating the terms of our Class F preferred stock expressly provide that the provisions thereof described above under "General Description of Preferred Stock—Voting Rights," insofar as they apply to the Class F preferred stock, shall supersede anything inconsistent contained in our charter and bylaws, and the articles supplementary designating any other class or series of our preferred stock that we may issue in the future may contain a similar provision.

Amendment to Charter and Bylaws

        Except as provided in the MGCL, amendments to our charter must be advised by our board of directors and approved by the affirmative vote of our stockholders entitled to cast a majority of all of the votes entitled to be cast on the matter. Except for amendments to certain provisions in our bylaws related to a written statement required to be furnished to stockholders in the event of certain distributions, our investment policy and restrictions, an annual report to stockholders and the definitions used in those sections of our bylaws, which amendments must be approved by the affirmative vote of our stockholders entitled to cast a majority of all of the votes entitled to be cast on the matter, our board of directors generally has the exclusive power to amend our bylaws.

Maryland Business Combination Law

        Under the MGCL, certain "business combinations" (including certain issuances of equity securities) between a Maryland corporation and any person who beneficially owns ten percent or more of the voting power of the corporation's outstanding voting stock, or an affiliate or associate of the corporation who beneficially owned ten percent or more of the voting power at any time within the preceding two years, in each case referred to as an "interested stockholder," or an affiliate thereof, are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. Thereafter, any such business combination must be approved by two super-majority stockholder votes unless, among other conditions, the corporation's common stockholders receive a minimum price (as defined in the MGCL) for their shares and the consideration is received in cash or in the same form as previously paid by the interested stockholder for its shares of common stock. The business combination provisions of the MGCL do not apply, however, to business combinations that are approved or exempted by the board of directors prior to the time that the interested stockholder becomes an interested stockholder. These provisions of the MGCL may delay, defer or prevent a transaction or a change in control of us that might involve a premium price for the common stock or otherwise be in the best interests of the stockholders.

Maryland Control Share Acquisitions Law

        The MGCL provides that holders of "control shares" of a Maryland corporation acquired in a "control share acquisition" have no voting rights except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter, excluding shares of stock owned by the acquirer, by officers of the corporation or by employees who are directors of the corporation. "Control shares" are voting shares of stock which, if aggregated with all other such shares of stock previously acquired by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power: (1) one-tenth or more but less than one-third, (2) one-third or more but less than a majority, or (3) a majority or more of all voting power. Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A "control share acquisition" means the acquisition of control shares, subject to certain exceptions.

        A person who has made or proposes to make a control share acquisition, upon satisfaction of certain conditions (including an undertaking to pay expenses), may compel the board of directors of the corporation to call a special meeting of stockholders to be held within 50 days of demand to consider the voting rights of the shares. If no request for a meeting is made, the corporation may itself present the question at any stockholders meeting.

        If voting rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then, subject to certain conditions and limitations, the corporation may redeem for fair value any and all of the control shares (except those for which voting rights have previously been approved). Fair value is determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquiror or, if a meeting of stockholders is held at which the voting rights of such shares are considered and not approved, as of the date of the meeting. If voting rights for control shares are approved at a stockholders meeting and the acquiror becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights, meaning that they may require us to repurchase their shares for their appraised value as determined pursuant to the MGCL. The fair value of the shares as determined for purposes of such appraisal rights may not be less than the highest price per share paid by the acquiror in the control share acquisition.

39


Table of Contents

        "Control share acquisition" does not include (1) shares acquired in a merger, consolidation or share exchange if the corporation is a party to the transaction, or (2) acquisitions exempted by the charter or bylaws of the corporation, adopted at any time before the acquisition of the shares.

        As permitted by the MGCL, our bylaws contain a provision exempting us from the control share acquisition statute. That bylaw provision states that the control share statute shall not apply to any acquisition by any person of shares of our stock. Our board of directors may, without the consent of any of our stockholders, amend or eliminate this bylaw provision at any time, which means that we would then become subject to the Maryland control share acquisition statute, and there can be no assurance that such provision will not be amended or eliminated by our board of directors at any time in the future.

Subtitle 8

        Subtitle 8 of Title 3 of the MGCL permits a Maryland corporation with a class of equity securities registered under the Exchange Act and at least three independent directors to elect, by provision in its charter or bylaws or a resolution of its board of directors and notwithstanding any contrary provision in the charter or bylaws, to be subject to any or all of five provisions, including:

        We have not elected to be subject to any of the provisions of Subtitle 8, including the provisions that would permit us to classify our board of directors or increase the vote required to remove a director without stockholder approval. Through provisions in our charter and bylaws unrelated to Subtitle 8, we (1) vest in our board of directors the exclusive power to fix the number of directors and (2) require, unless called by our chairman, our chief executive officer, our president or our board of directors, the request of stockholders entitled to cast not less than a majority of all the votes entitled to be cast at the meeting to call a special meeting of stockholders. The provisions of Subtitle 8 expressly provide that Subtitle 8 does not limit the power of a Maryland corporation, by provision in its charter, to confer on the holders of any class or series of preferred stock the right to elect one or more directors or designate the terms and voting powers of directors, which may vary among directors.

Special Meetings of Stockholders

        Pursuant to our bylaws, our chairman, our chief executive officer, our president or our board of directors may call a special meeting of our stockholders. Subject to the provisions of our bylaws, a special meeting of our stockholders to act on any matter that may properly be considered by our stockholders will also be called by our secretary upon the written request of stockholders entitled to cast a majority of all the votes entitled to be cast at the meeting on such matter, accompanied by the information required by our bylaws. Our secretary will inform the requesting stockholders of the reasonably estimated cost of preparing and delivering the notice of meeting (including our proxy materials), and the requesting stockholder must pay such estimated cost before our secretary may prepare and deliver the notice of the special meeting.

Advance Notice of Director Nomination and New Business

        Our bylaws provide that nominations of individuals for election as directors and proposals of business to be considered by stockholders at any annual meeting may be made only (1) pursuant to our notice of the meeting, (2) by or at the direction of our board of directors or (3) by any stockholder who was a stockholder of record as of the record date set by the board for the annual meeting, at the time of giving the notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of the individuals so nominated or on such other proposed business and who has complied with the advance notice procedures of our bylaws. Stockholders generally must provide notice to our secretary not earlier than the 150th day or later than the close of business on the 120th day before the first anniversary of the date our proxy statement was released for the preceding year's annual meeting.

        Only the business specified in the notice of the meeting may be brought before a special meeting of our stockholders. Nominations of individuals for election as directors at a special meeting of stockholders may be made only (1) by or at the direction of our board of directors, (2) by a stockholder that has requested that a special meeting be called for the purpose of electing directors in compliance with our bylaws or (3) if the special meeting has been called in accordance with our bylaws for the purpose of electing directors, by a stockholder who is a stockholder of record as of the record date set by the board for the special meeting, at the time of giving the notice required by our bylaws and at the time of the special meeting, who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the advance notice procedures of our bylaws. Stockholders generally must provide notice to our secretary not earlier than the 120th day before such special meeting or later than the later of the close of business on the 90th day before the special meeting or the tenth day after the first public announcement of the date of the special meeting and the nominees of our board of directors to be elected at the meeting.

        A stockholder's notice must contain certain information specified by our bylaws about the stockholder, its affiliates and any proposed business or nominee for election as a director, including information about the economic interest of the stockholder, its affiliates and any proposed nominee in us.

Effect of Certain Provisions of Maryland Law and our Charter and Bylaws

        Our charter contains restrictions on ownership and transfer of our stock intended to, among other purposes, assist us in maintaining our status as a REIT for United States federal and/or state income tax purposes. For example, our charter restricts any person from acquiring actual or constructive ownership of more than 9.8% (in value or number of shares, whichever is more restrictive) of our outstanding shares of common stock. See "Restrictions on Ownership and Transfers of Stock." These restrictions could delay or prevent a tender offer or change in control of our company or reduce the possibility that a third party will attempt such a transaction, even if a tender offer or a change of control were in our stockholders' interests or involved a premium price for our common stock, which could adversely affect the market price of our common stock.

        Our charter authorizes our board of directors to issue our preferred stock, including convertible preferred stock, without stockholder approval. The board of directors may establish the preferences, rights and other terms of any class or series of preferred stock we may issue, which may include voting rights and rights to convert such preferred stock into common stock. See "General Description of Preferred Stock." The issuance of preferred stock could delay or prevent a tender offer or change in control of our company or reduce the possibility that a third party will attempt such a transaction, even if a tender offer or a change of control were in our stockholders' interests or involved a premium price for our common stock, which could adversely affect the market price of our common stock.

41


Table of Contents

        Our charter and bylaws also provide that the number of directors may be established only by our board of directors, which prevents our stockholders from increasing the number of our directors and filling any vacancies created by such increase with their own nominees. The provisions of our bylaws discussed above under the captions "—Special Meetings of Stockholders" and "—Advance Notice of Director Nomination and New Business" require stockholders seeking to call a special meeting, nominate an individual for election as a director or propose other business at an annual or special meeting to comply with certain notice and information requirements. These provisions, alone or in combination, could make it more difficult for our stockholders to remove incumbent directors or fill vacancies on our board of directors with their own nominees and could delay or prevent a proxy contest, tender offer or change in control of our company or reduce the possibility that a third party will attempt such a contest or transaction, even if a proxy contest, tender offer or a change of control were in our stockholders' interests or involved a premium price for our common stock, which could adversely affect the market price of our common stock.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

        The following is a general summary of certain material U.S. federal income tax considerations regarding our election to be taxed as a REIT and the acquisition, ownership or disposition of our capital stock or debt securities. Supplemental U.S. federal income tax considerations relevant to holders of the securities offered by this prospectus (including warrants, preferred stock and depositary shares) may be provided in the prospectus supplement that relates to those securities. Unless otherwise expressly stated or the context otherwise requires, all references to the "Company," "Realty Income," "our," "we" and "us" and all similar references appearing under this caption "United States Federal Income Tax Considerations" mean Realty Income Corporation excluding its subsidiaries. This summary is for general information only and is not tax advice. The information in this summary is based on:

in each case, as of the date of this prospectus. In addition, the administrative interpretations and practices of the IRS include its practices and policies as expressed in private letter rulings that are not binding on the IRS except with respect to the particular taxpayers who requested and received those rulings. Future legislation, Treasury Regulations, administrative interpretations and practices and/or court decisions may adversely affect the tax considerations contained in this discussion. Any such change could apply retroactively to transactions preceding the date of the change. We have not requested, and do not plan to request, any rulings from the IRS that we qualify as a REIT, and the statements in this prospectus are not binding on the IRS or any court. Thus, we can provide no assurance that the tax considerations contained in this discussion will not be challenged by the IRS or will be sustained by a court if challenged by the IRS. This summary does not discuss any state, local or non-U.S. tax consequences, or any tax consequences arising under any federal tax laws other than federal income tax laws, associated with the acquisition, ownership or disposition of our capital stock or debt securities, or our election to be taxed as a REIT.

        You are urged to consult your tax advisor regarding the tax consequences to you of:

Taxation of Our Company

        General.    We have elected to be taxed as a REIT under Sections 856 through 860 of the Code, commencing with our taxable year ended December 31, 1994. We believe that we have been organized and have operated in a manner that has allowed us to qualify for taxation as a REIT under the Code commencing with our taxable year ended December 31, 1994, and we intend to continue to be organized and operate in this manner. However, qualification and taxation as a REIT depend upon our ability to meet the various qualification tests imposed under the Code, including through actual annual operating results, asset composition, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that we have been organized and have operated, or will continue to be organized and operate, in a manner so as to qualify or remain qualified as a REIT. See "—Failure to Qualify" for any potential tax consequences if we fail to qualify as a REIT.

43


Table of Contents

        The sections of the Code and the corresponding Treasury Regulations that relate to qualification and taxation as a REIT are highly technical and complex. The following discussion sets forth certain material aspects of the sections of the Code that govern the federal income tax treatment of a REIT and the holders of certain of its securities. This summary is qualified in its entirety by the applicable Code provisions, Treasury Regulations promulgated under the Code, and administrative and judicial interpretations thereof.

        Latham & Watkins LLP has acted as our tax counsel in connection with our filing of this prospectus and our election to be taxed as a REIT. Latham & Watkins LLP has rendered an opinion to us to the effect that, commencing with our taxable year ending December 31, 1994, we have been organized and have operated in conformity with the requirements for qualification and taxation as a REIT under the Code, and our proposed method of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT under the Code. It must be emphasized that this opinion was based on various assumptions and representations as to factual matters, including representations made by us in a factual certificate provided by one of our officers. In addition, this opinion was based upon our factual representations set forth in this prospectus. Moreover, our qualification and taxation as a REIT depend upon our ability to meet the various qualification tests imposed under the Code, which are discussed below, including through actual annual operating results, asset composition, distribution levels and diversity of stock ownership, the results of which have not been and will not be reviewed by Latham & Watkins LLP. Accordingly, no assurance can be given that our actual results of operation for any particular taxable year have satisfied or will satisfy those requirements. Further, the anticipated federal income tax treatment described herein may be changed, perhaps retroactively, by legislative, administrative or judicial action at any time. Latham & Watkins LLP has no obligation to update its opinion subsequent to the date of such opinion.

        Provided we qualify for taxation as a REIT, we generally will not be required to pay federal corporate income taxes on our REIT taxable income that is currently distributed to our stockholders. This treatment substantially eliminates the "double taxation" that ordinarily results from investment in a C corporation. A C corporation is a corporation that generally is required to pay tax at the corporate level. Double taxation means taxation once at the corporate level when income is earned and once again at the stockholder level when the income is distributed. We will, however, be required to pay federal income tax as follows:

44


Table of Contents

45


Table of Contents

        From time to time we may own properties in other countries which may impose taxes on our operations within their jurisdictions. To the extent possible, we will structure our activities to minimize our non-U.S. tax liability. However, there can be no assurance that we will be able to eliminate our non-U.S. tax liability or reduce it to a specified level. Furthermore, as a REIT, both we and our stockholders will derive little or no benefit from foreign tax credits arising from those non-U.S. taxes.

        Requirements for Qualification as a REIT.    The Code defines a REIT as a corporation, trust or association:

        The Code provides that conditions (1) to (4), inclusive, must be met during the entire taxable year and that condition (5) must be met during at least 335 days of a taxable year of 12 months, or during a proportionate part of a taxable year of less than 12 months. Conditions (5) and (6) do not apply until after the first taxable year for which an election is made to be taxed as a REIT. For purposes of condition (6), the term "individual" includes a supplemental unemployment compensation benefit plan, a private foundation or a portion of a trust permanently set aside or used exclusively for charitable purposes, but generally does not include a qualified pension plan or profit sharing trust.

        We believe that we have been organized and have operated in a manner that has allowed us, and will continue to allow us, to satisfy conditions (1) through (7) inclusive, during the relevant time periods. In addition, our charter provides for restrictions regarding ownership and transfer of our shares that are intended to assist us in continuing to satisfy the share ownership requirements described in (5) and (6) above. A description of the share ownership and transfer restrictions relating to our capital stock is contained in the discussion under the heading "Restrictions on Ownership and Transfer." These restrictions, however, do not ensure that we have previously satisfied, and may not ensure that we will, in all cases, be able to continue to satisfy, the share ownership requirements described in conditions (5) and (6) above. If we fail to satisfy these share ownership requirements, except as provided in the next sentence, our status as a REIT will terminate. If, however, we comply with the rules contained in applicable Treasury Regulations that require us to ascertain the actual

46


Table of Contents

ownership of our shares and we do not know, or would not have known through the exercise of reasonable diligence, that we failed to meet the requirement described in condition (6) above, we will be treated as having met this requirement. See "—Failure to Qualify."

        In addition, we may not maintain our status as a REIT unless our taxable year is the calendar year. We have and will continue to have a calendar taxable year.

        Ownership of Interests in Partnerships, Limited Liability Companies and Qualified REIT Subsidiaries.    In the case of a REIT that is a partner in a partnership or a member in a limited liability company treated as a partnership for federal income tax purposes, Treasury Regulations provide that the REIT will be deemed to own its proportionate share of the assets of the partnership or limited liability company, as the case may be, based on its interest in partnership capital, subject to special rules relating to the 10% asset test described below. Also, the REIT will be deemed to be entitled to its proportionate share of the income of that entity. The assets and gross income of the partnership or limited liability company retain the same character in the hands of the REIT for purposes of Section 856 of the Code, including satisfying the gross income tests and the asset tests. Thus, our pro rata share of the assets and items of income of any partnership or limited liability company treated as a partnership or disregarded entity for federal income tax purposes in which we directly or indirectly own an interest is treated as our assets and items of income for purposes of applying the requirements described in this discussion, including the gross income and asset tests described below. A brief summary of the rules governing the federal income taxation of partnerships and limited liability companies is set forth below in "—Tax Aspects of the Subsidiary Partnerships and the Limited Liability Companies."

        We generally have control of our subsidiary partnerships and limited liability companies and intend to operate them in a manner consistent with the requirements for our qualification as a REIT. We may from time to time be a limited partner or non-managing member in some of our partnerships and limited liability companies. If a partnership or limited liability company in which we own an interest takes or expects to take actions that could jeopardize our status as a REIT or require us to pay tax, we may be forced to dispose of our interest in such entity. In addition, it is possible that a partnership or limited liability company could take an action which could cause us to fail a gross income or asset test, and that we would not become aware of such action in time to dispose of our interest in the partnership or limited liability company or take other corrective action on a timely basis. In that case, we could fail to qualify as a REIT unless we were entitled to relief, as described below.

        We may from time to time own and operate certain properties through wholly-owned subsidiaries that we intend to be treated as "qualified REIT subsidiaries" under the Code. A corporation will qualify as our qualified REIT subsidiary if we own 100% of the corporation's outstanding stock and do not elect with the subsidiary to treat it as a "taxable REIT subsidiary," as described below. A qualified REIT subsidiary is not treated as a separate corporation, and all assets, liabilities and items of income, gain, loss, deduction and credit of a qualified REIT subsidiary are treated as assets, liabilities and items of income, gain, loss, deduction and credit of the parent REIT for all purposes under the Code, including all REIT qualification tests. Thus, in applying the federal tax requirements described in this discussion, any qualified REIT subsidiaries we own are ignored, and all assets, liabilities and items of income, gain, loss, deduction and credit of such corporations are treated as our assets, liabilities and items of income, gain, loss, deduction and credit. A qualified REIT subsidiary is not subject to federal income tax, and our ownership of the stock of a qualified REIT subsidiary will not violate the restrictions on ownership of securities, as described below under "—Asset Tests."

        Ownership of Interests in Taxable REIT Subsidiaries.    We currently own an interest in a number of taxable REIT subsidiaries and may acquire securities in additional taxable REIT subsidiaries in the future. A taxable REIT subsidiary is a corporation other than a REIT in which a REIT directly or indirectly holds stock, and that has made a joint election with such REIT to be treated as a taxable

47


Table of Contents

REIT subsidiary. If a taxable REIT subsidiary owns more than 35% of the total voting power or value of the outstanding securities of another corporation, such other corporation will also be treated as a taxable REIT subsidiary. Other than some activities relating to lodging and health care facilities, a taxable REIT subsidiary may generally engage in any business, including the provision of customary or non-customary services to tenants of its parent REIT. A taxable REIT subsidiary is subject to federal income tax as a regular C corporation. In addition, a taxable REIT subsidiary may be prevented from deducting interest on debt funded directly or indirectly by its parent REIT if certain tests regarding the taxable REIT subsidiary's debt to equity ratio and interest expense are not satisfied. A REIT's ownership of securities of a taxable REIT subsidiary is not subject to the 5% or 10% asset test described below. See "—Asset Tests."

        Income Tests.    We must satisfy two gross income requirements annually to maintain our qualification as a REIT. First, in each taxable year we must derive directly or indirectly at least 75% of our gross income (excluding gross income from prohibited transactions, certain hedging transactions and certain foreign currency gains) from investments relating to real property or mortgages on real property, including "rents from real property," dividends from other REITs and, in certain circumstances, interest, or certain types of temporary investments. Second, in each taxable year we must derive at least 95% of our gross income (excluding gross income from prohibited transactions, certain hedging transactions, and certain foreign currency gains) from the real property investments described above or dividends, interest and gain from the sale or disposition of stock or securities, or from any combination of the foregoing. For these purposes, the term "interest" generally does not include any amount received or accrued, directly or indirectly, if the determination of all or some of the amount depends in any way on the income or profits of any person. However, an amount received or accrued generally will not be excluded from the term "interest" solely by reason of being based on a fixed percentage or percentages of receipts or sales.

        Rents we receive from a tenant will qualify as "rents from real property" for the purpose of satisfying the gross income requirements for a REIT described above only if all of the following conditions are met:

48


Table of Contents

        We generally do not intend to take actions we believe will cause us to fail to satisfy the rental conditions described above. However, we may intentionally fail to satisfy some of these conditions to the extent we determine, based on the advice of our tax counsel, that the failure will not jeopardize our tax status as a REIT. In addition, with respect to the limitation on the rental of personal property, we generally have not obtained appraisals of the real property and personal property leased to tenants. Accordingly, there can be no assurance that the IRS will not disagree with our determinations of value.

        From time to time, we may enter into hedging transactions with respect to one or more of our assets or liabilities. Our hedging activities may include entering into interest rate swaps, caps, and floors, options to purchase these items, and futures and forward contracts. Income from a hedging transaction, including gain from the sale or disposition of such a transaction, that is clearly identified as a hedging transaction as specified in the Code will not constitute gross income and thus will be exempt from the 75% and 95% gross income tests. The term "hedging transaction," as used above, generally means (A) any transaction we enter into in the normal course of our business primarily to manage risk of (1) interest rate changes or fluctuations with respect to borrowings made or to be made by us to acquire or carry real estate assets, or (2) currency fluctuations with respect to an item of qualifying income under the 75% or 95% gross income test and (B) for taxable years beginning after December 31, 2015, new transactions entered into to hedge the income or loss from prior hedging transactions, where the property or indebtedness which was the subject of the prior hedging transaction was extinguished or disposed of. To the extent that we do not properly identify such transactions as hedges or we hedge with other types of financial instruments, the income from those transactions is not likely to be treated as qualifying income for purposes of the gross income tests. We intend to structure any hedging transactions in a manner that does not jeopardize our status as a REIT.

        From time to time we may own properties or entities located outside the United States. These acquisitions could cause us to incur foreign currency gains or losses. Any foreign currency gains, to the extent attributable to specified items of qualifying income or gain, or specified qualifying assets, however, generally will not constitute gross income for purposes of the 75% and 95% gross income tests, and therefore will be excluded from these tests.

        To the extent our taxable REIT subsidiaries pay dividends, we generally will derive our allocable share of such dividend income. Such dividend income will qualify under the 95%, but not the 75%, gross income test.

        We will monitor the amount of the dividend and other income from our taxable REIT subsidiaries and will take actions intended to keep this income, and any other nonqualifying income, within the

49


Table of Contents

limitations of the gross income tests. Although we expect these actions will be sufficient to prevent a violation of the gross income tests, we cannot guarantee that such actions will in all cases prevent such a violation.

        If we fail to satisfy one or both of the 75% or 95% gross income tests for any taxable year, we may nevertheless qualify as a REIT for the year if we are entitled to relief under certain provisions of the Code. We generally may make use of the relief provisions if:

        It is not possible, however, to state whether in all circumstances we would be entitled to the benefit of these relief provisions. For example, if we fail to satisfy the gross income tests because nonqualifying income that we intentionally accrue or receive exceeds the limits on nonqualifying income, the IRS could conclude that our failure to satisfy the tests was not due to reasonable cause. If these relief provisions do not apply to a particular set of circumstances, we will not qualify as a REIT. As discussed above in "—Taxation of Our Company—General," even if these relief provisions apply, and we retain our status as a REIT, a tax would be imposed with respect to our nonqualifying income. We may not always be able to comply with the gross income tests for REIT qualification despite periodic monitoring of our income.

        Prohibited Transaction Income.    Any gain that we realize on the sale of property held as inventory or otherwise held primarily for sale to customers in the ordinary course of business will be treated as income from a prohibited transaction that is subject to a 100% penalty tax, unless certain safe harbor exceptions apply. Our gain would include any gain realized by our qualified REIT subsidiaries and our share of any gain realized by any of the partnerships or limited liability companies in which we own an interest. This prohibited transaction income may also adversely affect our ability to satisfy the gross income tests for qualification as a REIT. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. We intend to hold our properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing and owning our properties and to make occasional sales of the properties as are consistent with our investment objectives. We do not intend to enter into any sales that are prohibited transactions. However, the IRS may successfully contend that some or all of the sales made by us or our subsidiary partnerships or limited liability companies are prohibited transactions. We would be required to pay the 100% penalty tax on our allocable share of the gains resulting from any such sales.

        Penalty Tax.    Any redetermined rents, redetermined deductions, excess interest or (for taxable years beginning after December 31, 2015) redetermined TRS service income we generate will be subject to a 100% penalty tax. In general, redetermined rents are rents from real property that are overstated as a result of any services furnished to any of our tenants by a taxable REIT subsidiary of ours, redetermined deductions and excess interest represent any amounts that are deducted by a taxable REIT subsidiary of ours for amounts paid to us that are in excess of the amounts that would have been deducted based on arm's length negotiations, and redetermined TRS service income is income of a taxable REIT subsidiary that is understated as a result of services provided to us or on our behalf.. Rents we receive will not constitute redetermined rents if they qualify for certain safe harbor provisions contained in the Code.

        We do not believe we have been, and do not expect to be, subject to this penalty tax, although our rental or service arrangements may not satisfy the safe-harbor provisions described above. These

50


Table of Contents

determinations are inherently factual, and the IRS has broad discretion to assert that amounts paid between related parties should be reallocated to clearly reflect their respective incomes. If the IRS successfully made such an assertion, we would be required to pay a 100% penalty tax on the excess of an arm's length fee for tenant services over the amount actually paid.

        Asset Tests.    At the close of each calendar quarter of our taxable year, we must also satisfy certain tests relating to the nature and diversification of our assets. First, at least 75% of the value of our total assets must be represented by real estate assets, cash, cash items and U.S. government securities. For purposes of this test, the term "real estate assets" generally means real property (including interests in real property and interests in mortgages on real property) and shares (or transferable certificates of beneficial interest) in other REITs, as well as any stock or debt instrument attributable to the investment of the proceeds of a stock offering or a public offering of debt with a term of at least five years, but only for the one-year period beginning on the date the REIT receives such proceeds. For taxable years beginning after December 31, 2015, the term "real estate assets" also includes debt instruments of publicly offered REITs, personal property securing a mortgage secured by both real property and personal property if the fair market value of such personal property does not exceed 15% of the total fair market value of all such property, and personal property leased in connection with a lease of real property for which the rent attributable to personal property is not greater than 15% of the total rent received under the lease.

        Second, not more than 25% of the value of our total assets may be represented by securities (including securities of taxable REIT subsidiaries), other than those securities includable in the 75% asset test.

        Third, of the investments included in the 25% asset class, and except for investments in other REITs, our qualified REIT subsidiaries and taxable REIT subsidiaries, the value of any one issuer's securities may not exceed 5% of the value of our total assets, and we may not own more than 10% of the total vote or value of the outstanding securities of any one issuer except, in the case of the 10% value test, securities satisfying the "straight debt" safe-harbor or securities issued by a partnership that itself would satisfy the 75% income test if it were a REIT. Certain types of securities we may own are disregarded as securities solely for purposes of the 10% value test, including, but not limited to, any loan to an individual or an estate, any obligation to pay rents from real property and any security issued by a REIT. In addition, solely for purposes of the 10% value test, the determination of our interest in the assets of a partnership or limited liability company in which we own an interest will be based on our proportionate interest in any securities issued by the partnership or limited liability company, excluding for this purpose certain securities described in the Code. From time to time we may own securities (including debt securities) of issuers that do not qualify as a REIT, a qualified REIT subsidiary or a taxable REIT subsidiary. We intend that our ownership of any such securities will be structured in a manner that allows us to comply with the asset tests described above.

        Fourth, not more than 25% (20% for taxable years beginning after December 31, 2017) of the value of our total assets may be represented by the securities of one or more taxable REIT subsidiaries. We currently own 100% of the stock of certain corporations that have elected, together with us, to be treated as our taxable REIT subsidiaries. So long as each of these companies qualifies as a taxable REIT subsidiary, we will not be subject to the 5% asset test, the 10% voting securities limitation or the 10% value limitation with respect to our ownership of their stock. We may acquire securities in other taxable REIT subsidiaries in the future. We believe that the aggregate value of our taxable REIT subsidiaries has not exceeded, and in the future will not exceed, 25% (20% for taxable years beginning after December 31, 2017) of the aggregate value of our gross assets. We generally do not obtain independent appraisals to support these conclusions. In addition, there can be no assurance that the IRS will not disagree with our determinations of value.

51


Table of Contents

        Fifth, for taxable years beginning after December 31, 2015, not more than 25% of the value of our total assets may be represented by debt instruments of publicly offered REITs to the extent those debt instruments would not be real estate assets but for the inclusion of debt instruments of publicly offered REITs in the meaning of real estate assets effective for taxable years beginning after December 31, 2015, as described above.

        The asset tests must be satisfied at the close of each calendar quarter of our taxable year in which we (directly or through our qualified REIT subsidiaries, partnerships or limited liability companies) acquire securities in the applicable issuer, and also at the close of each calendar quarter in which we increase our ownership of securities of such issuer (including as a result of increasing our interest in a partnership or limited liability company that owns such securities, or acquiring other assets). For example, our indirect ownership of securities of each issuer may increase as a result of our capital contributions to, or the redemption of other partners' or members' interests in, a partnership or limited liability company in which we have an ownership interest. However, after initially meeting the asset tests at the close of any quarter, we will not lose our status as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values. If we fail to satisfy an asset test because we acquire securities or other property during a quarter (including as a result of an increase in our interests in a partnership or limited liability company), we may cure this failure by disposing of sufficient nonqualifying assets within 30 days after the close of that quarter. We believe that we have maintained, and we intend to maintain, adequate records of the value of our assets to ensure compliance with the asset tests. If we fail to cure any noncompliance with the asset tests within the 30-day cure period, we would cease to qualify as a REIT unless we are eligible for certain relief provisions discussed below.

        Certain relief provisions may be available to us if we discover a failure to satisfy the asset tests described above after the 30-day cure period. Under these provisions, we will be deemed to have met the 5% and 10% asset tests if the value of our nonqualifying assets (i) does not exceed the lesser of (a) 1% of the total value of our assets at the end of the applicable quarter or (b) $10,000,000, and (ii) we dispose of the nonqualifying assets or otherwise satisfy such tests within (a) six months after the last day of the quarter in which the failure to satisfy the asset tests is discovered or (b) the period of time prescribed by Treasury Regulations to be issued. For violations of any of the asset tests due to reasonable cause and not due to willful neglect and that are, in the case of the 5% and 10% asset tests, in excess of the de minimis exception described above, we may avoid disqualification as a REIT after the 30-day cure period by taking steps including (i) the disposition of sufficient nonqualifying assets, or the taking of other actions, which allow us to meet the asset tests within (a) six months after the last day of the quarter in which the failure to satisfy the asset tests is discovered or (b) the period of time prescribed by Treasury Regulations to be issued, (ii) paying a tax equal to the greater of (a) $50,000 or (b) the highest corporate tax rate multiplied by the net income generated by the nonqualifying assets, and (iii) disclosing certain information to the IRS.

        Although we believe we have satisfied the asset tests described above and plan to take steps to ensure that we satisfy such tests for any quarter with respect to which retesting is to occur, there can be no assurance that we will always be successful, or will not require a reduction in our overall interest in an issuer (including in a taxable REIT subsidiary). If we fail to cure any noncompliance with the asset tests in a timely manner, and the relief provisions described above are not available, we would cease to qualify as a REIT.

        Annual Distribution Requirements.    To maintain our qualification as a REIT, we are required to distribute dividends, other than capital gain dividends, to our stockholders in an amount at least equal to the sum of:

52


Table of Contents

        For these purposes, our "REIT taxable income" is computed without regard to the dividends paid deduction and our net capital gain. In addition, for purposes of this test, non-cash income generally means income attributable to leveled stepped rents, original issue discount on purchase money debt, cancellation of indebtedness, or a like-kind exchange that is later determined to be taxable.

        In addition, our "REIT taxable income" will be reduced by any taxes we are required to pay on any gain we recognize from the disposition of any asset we acquired from a corporation that is or has been a C corporation in a transaction in which our basis in the asset is less than the fair market value of the asset, in each case determined as of the date on which we acquired the asset, within the five-year period following our acquisition of such asset, as described above under "—General."

        We generally must pay, or be treated as paying, the distributions described above in the taxable year to which they relate. At our election, a distribution will be treated as paid in a taxable year if it is declared before we timely file our tax return for such year and paid on or before the first regular dividend payment after such declaration, provided such payment is made during the 12-month period following the close of such year. These distributions are treated as received by our stockholders in the year in which they are paid. This is so even though these distributions relate to the prior year for purposes of the 90% distribution requirement. In order to be taken into account for purposes of our distribution requirement, unless (for distributions made in taxable years beginning after December 31, 2014) we qualify as a "publicly offered REIT," the amount distributed must not be preferential—i.e., every stockholder of the class of stock to which a distribution is made must be treated the same as every other stockholder of that class, and no class of stock may be treated other than according to its dividend rights as a class. We believe that we are, and expect we will continue to be, a "publicly offered REIT." To the extent that we do not distribute all of our net capital gain, or distribute at least 90%, but less than 100%, of our "REIT taxable income," as adjusted, we will be required to pay tax on the undistributed amount at regular corporate tax rates. We believe that we have made, and we intend to continue to make, timely distributions sufficient to satisfy these annual distribution requirements and to minimize our corporate tax obligations.

        We expect that our REIT taxable income will be less than our cash flow because of depreciation and other non-cash charges included in computing REIT taxable income. Accordingly, we anticipate that we generally will have sufficient cash or liquid assets to enable us to satisfy the distribution requirements described above. However, from time to time, we may not have sufficient cash or other liquid assets to meet these distribution requirements due to timing differences between the actual receipt of income and actual payment of deductible expenses, and the inclusion of income and deduction of expenses in determining our taxable income. If these timing differences occur, we may borrow funds to pay dividends in order to meet the distribution requirements.

        Under some circumstances, we may be able to rectify an inadvertent failure to meet the 90% distribution requirement for a year by paying "deficiency dividends" to our stockholders in a later year, which may be included in our deduction for dividends paid for the earlier year. Thus, we may be able to avoid being taxed on amounts distributed as deficiency dividends, subject to the 4% excise tax described below. However, we will be required to pay interest to the IRS based upon the amount of any deduction claimed for deficiency dividends.

        Furthermore, we will be required to pay a 4% excise tax to the extent we fail to distribute during each calendar year at least the sum of 85% of our ordinary income for such year, 95% of our capital gain net income for the year and any undistributed taxable income from prior periods. Any ordinary income and net capital gain on which this excise tax is imposed for any year is treated as an amount distributed during that year for purposes of calculating such tax.

        For purposes of the 90% distribution requirement and excise tax described above, dividends declared during the last three months of the taxable year, payable to stockholders of record on a

53


Table of Contents

specified date during such period and paid during January of the following year, will be treated as paid by us and received by our stockholders on December 31 of the year in which they are declared.

        Like-Kind Exchanges.    We may dispose of properties in transactions intended to qualify as like-kind exchanges under the Code. Such like-kind exchanges are intended to result in the deferral of gain for federal income tax purposes. The failure of any such transaction to qualify as a like-kind exchange could require us to pay federal income tax, possibly including the 100% prohibited transaction tax, depending on the facts and circumstances surrounding the particular transaction.

        Failure to Qualify.    If we discover a violation of a provision of the Code that would result in our failure to qualify as a REIT, certain specified cure provisions may be available to us. Except with respect to violations of the gross income tests and asset tests (for which the cure provisions are described above), and provided the violation is due to reasonable cause and not due to willful neglect, these cure provisions generally impose a $50,000 penalty for each violation in lieu of a loss of REIT status. If we fail to satisfy the requirements for taxation as a REIT in any taxable year, and the relief provisions do not apply, we will be required to pay tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates. Distributions to stockholders in any year in which we fail to qualify as a REIT will not be deductible by us, and we will not be required to distribute any amounts to our stockholders. As a result, we anticipate that our failure to qualify as a REIT would reduce the cash available for distribution by us to our stockholders. In addition, if we fail to qualify as a REIT, all distributions to stockholders will be taxable as regular corporate dividends to the extent of our current and accumulated earnings and profits. In such event, corporate distributees may be eligible for the dividends-received deduction. In addition, non-corporate stockholders, including individuals, may be eligible for the preferential tax rates on qualified dividend income. Unless entitled to relief under specific statutory provisions, we would also be ineligible to elect to be treated as a REIT for the four taxable years following the year for which we lose our qualification. It is not possible to state whether in all circumstances we would be entitled to this statutory relief.

Tax Aspects of the Subsidiary Partnerships and the Limited Liability Companies

        General.    From time to time, we may own, directly or indirectly, interests in various partnerships and limited liability companies. We expect these will be treated as partnerships or disregarded entities for federal income tax purposes. In general, entities that are treated as partnerships or disregarded entities for federal income tax purposes are "pass-through" entities which are not required to pay federal income tax. Rather, partners or members of such entities are allocated their shares of the items of income, gain, loss, deduction and credit of the partnership or limited liability company, and are potentially required to pay tax on this income, without regard to whether they receive a distribution from the partnership or limited liability company. We will include in our income our share of these partnership and limited liability company items for purposes of the various gross income tests, the computation of our REIT taxable income, and the REIT distribution requirements. Moreover, for purposes of the asset tests, we will include our pro rata share of assets held by these partnerships and limited liability companies, based on our capital interests in each such entity. See "—Taxation of Our Company."

        Entity Classification.    Our interests in the subsidiary partnerships and limited liability companies involve special tax considerations, including the possibility that the IRS might challenge the status of these entities as partnerships (or disregarded entities). For example, an entity that would otherwise be treated as a partnership for federal income tax purposes may nonetheless be taxable as a corporation if it is a "publicly traded partnership" and certain other requirements are met. A partnership or limited liability company would be treated as a publicly traded partnership if its interests are traded on an established securities market or are readily tradable on a secondary market or a substantial equivalent thereof, within the meaning of applicable Treasury Regulations. We do not anticipate that any

54


Table of Contents

subsidiary partnership or limited liability company will be treated as a publicly traded partnership that is taxable as a corporation. However, if any such entity were treated as a corporation, it would be required to pay an entity-level tax on its income. In this situation, the character of our assets and items of gross income would change and could prevent us from satisfying the REIT asset tests and possibly the REIT income tests. See "—Taxation of Our Company—Asset Tests" and "—Income Tests." This, in turn, could prevent us from qualifying as a REIT. See "—Failure to Qualify" for a discussion of the effect of our failure to meet these tests. In addition, a change in the tax status of one or more of the partnerships or limited liability companies might be treated as a taxable event. If so, we might incur a tax liability without any related cash payment. We believe that each of our partnerships and limited liability companies have been and will continue to be treated as partnerships or disregarded entities for federal income tax purposes.

        Allocations of Income, Gain, Loss and Deduction.    A partnership or limited liability company agreement will generally determine the allocation of income and losses among partners or members, provided such allocations comply with the provisions of Section 704(b) of the Code and the related Treasury Regulations. If an allocation of partnership income or loss does not comply with the requirements of Section 704(b) of the Code and the Treasury Regulations thereunder, the item subject to the allocation will be reallocated in accordance with the partners' or members' interests in the partnership or limited liability company, as the case may be. This reallocation will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners or members with respect to such item. We intend that the allocations of taxable income and loss in each of the partnerships and limited liability companies in which we own an interest from time to time comply with the requirements of Section 704(b) of the Code and the Treasury Regulations thereunder.

        Tax Allocations With Respect to the Properties.    Under Section 704(c) of the Code, income, gain, loss and deduction attributable to appreciated or depreciated property that is contributed to a partnership or limited liability company in exchange for an interest in the partnership or limited liability company must be allocated in a manner so that the contributing partner or member is charged with the unrealized gain or benefits from the unrealized loss associated with the property at the time of the contribution. The amount of the unrealized gain or unrealized loss generally is equal to the difference between the fair market value or book value and the adjusted tax basis of the contributed property at the time of contribution, as adjusted from time to time. These allocations are solely for federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the partners or members. Some of the partnerships and/or limited liability companies in which we own an interest were formed by way of contributions of appreciated property. The relevant partnership and/or limited liability company agreements require that allocations be made in a manner consistent with Section 704(c) of the Code. Under Section 704(c) of the Code we could be allocated less depreciation or more gain on sale with respect to a contributed property than the amounts that would have been allocated to us if we had instead acquired the contributed property with an initial tax basis equal to its fair market value.

        Any property acquired by a subsidiary partnership or limited liability company in a taxable transaction will initially have a tax basis equal to its fair market value, and Section 704(c) of the Code generally will not apply.

        Partnership Audit Rules.    The recently enacted Bipartisan Budget Act of 2015 changes the rules applicable to U.S. federal income tax audits of partnerships. Under the new rules (which are generally effective for taxable years beginning after December 31, 2017), among other changes and subject to certain exceptions, any audit adjustment to items of income, gain, loss, deduction, or credit of a partnership (and any partner's distributive share thereof) is determined, and taxes, interest, or penalties attributable thereto are assessed and collected, at the partnership level. Although it is uncertain how

55


Table of Contents

these new rules will be implemented, it is possible that they could result in partnerships in which we directly or indirect invest being required to pay additional taxes, interest and penalties as a result of an audit adjustment, and we, as a direct or indirect partner of these partnerships, could be required to bear the economic burden of those taxes, interest, and penalties even though we, as a REIT, may not otherwise have been required to pay additional corporate-level taxes as a result of the related audit adjustment. The changes created by these new rules are sweeping and in many respects dependent on the promulgation of future regulations or other guidance by the U.S. Treasury. Investors are urged to consult their tax advisors with respect to these changes and their potential impact on their investment in our common stock.

        Tax Liabilities and Attributes Inherited Through Merger or Acquisitions.    We may from time to time acquire other REITs through merger or acquisition. If any such REIT failed to qualify as a REIT for any of its taxable years, such REIT would be liable for (and we, as the surviving corporation in the merger or acquisition, would be obligated to pay) U.S. federal income tax on its taxable income at regular rates. Furthermore, after the merger or acquisition is effective, the asset and income tests will apply to all of our assets, including the assets we acquire from such REIT, and to all of our income, including the income derived from the assets we acquire from such REIT. As a result, the nature of the assets that we acquire from such REITs and the income we derive from those assets may have an effect on our tax status as a REIT.

Federal Income Tax Considerations for Holders of Our Capital Stock and Debt Securities

        The following summary describes the material U.S. federal income tax consequences to you of acquiring, owning and disposing of our capital stock or debt securities. This summary assumes you hold shares of our capital stock or debt securities as "capital assets" (generally, property held for investment within the meaning of Section 1221 of the Code). It does not address all U.S. federal income tax consequences that may be relevant to you in light of your particular circumstances. In addition, except where specifically noted, this discussion does not address the tax consequences relevant to persons subject to special rules, including, without limitation:

56


Table of Contents

        If you are considering acquiring our capital stock or debt securities, you should consult your tax advisor concerning the application of U.S. federal income tax laws to your particular situation as well as any consequences of the acquisition, ownership and disposition of our capital stock or debt securities arising under the laws of any state, local or non-U.S. taxing jurisdiction or under any applicable tax treaty.

        When we use the term "U.S. holder," we mean a holder of shares of our capital stock or debt securities who, for U.S. federal income tax purposes, is:

        If you are an individual, corporation, estate or trust that holds shares of our capital stock or debt securities and you are not a U.S. holder, you are a "non-U.S. holder."

        If an entity treated as a partnership for U.S. federal income tax purposes holds shares of our capital stock or debt securities, the tax treatment of a partner in the partnership generally will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding shares of our capital stock or debt securities and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

Taxation of Taxable U.S. Holders of Our Capital Stock

        Distributions Generally.    Distributions out of our current or accumulated earnings and profits will be treated as dividends and, other than with respect to capital gain dividends and certain amounts which have previously been subject to corporate level tax, as discussed below, will be taxable to our taxable U.S. holders as ordinary income when actually or constructively received. See "—Tax Rates" below. As long as we qualify as a REIT, these distributions will not be eligible for the dividends-received deduction in the case of U.S. holders that are corporations or, except to the extent described in "—Tax Rates" below, the preferential rates on qualified dividend income applicable to non-corporate U.S. holders, including individuals. For purposes of determining whether distributions to holders of our capital stock are out of our current or accumulated earnings and profits, our earnings and profits will be allocated first to our outstanding preferred stock, if any, and then to our outstanding common stock.

        To the extent that we make distributions on our capital stock in excess of our current and accumulated earnings and profits allocable to such stock, these distributions will be treated first as a tax-free return of capital to a U.S. holder. This treatment will reduce the U.S. holder's adjusted tax basis in such shares of stock by the amount of the distribution, but not below zero. Distributions in excess of our current and accumulated earnings and profits and in excess of a U.S. holder's adjusted tax basis in its shares will be taxable as capital gain. Such gain will be taxable as long-term capital gain if the shares have been held for more than one year. Dividends we declare in October, November, or December of any year and which are payable to a holder of record on a specified date in any of these months will be treated as both paid by us and received by the holder on December 31 of that year,

57


Table of Contents

provided we actually pay the dividend on or before January 31 of the following year. U.S. holders may not include in their own income tax returns any of our net operating losses or capital losses.

        Capital Gain Dividends.    Dividends that we properly designate as capital gain dividends will be taxable to our taxable U.S. holders as a gain from the sale or disposition of a capital asset held for more than one year, to the extent that such gain does not exceed our actual net capital gain for the taxable year and, for taxable years beginning after December 31, 2015, may not exceed our dividends paid for the taxable year, including dividends paid the following year that are treated as paid in the current year. U.S. holders that are corporations may, however, be required to treat up to 20% of certain capital gain dividends as ordinary income. If we properly designate any portion of a dividend as a capital gain dividend then, except as otherwise required by law, we presently intend to allocate a portion of the total capital gain dividends paid or made available to holders of all classes of our capital stock for the year to the holders of each class of our capital stock in proportion to the amount that our total dividends, as determined for U.S. federal income tax purposes, paid or made available to the holders of each such class of our capital stock for the year bears to the total dividends, as determined for U.S. federal income tax purposes, paid or made available to holders of all classes of our capital stock for the year. In addition, except as otherwise required by law, we will make a similar allocation with respect to any undistributed long term capital gains which are to be included in our stockholders' long term capital gains, based on the allocation of the capital gain amount which would have resulted if those undistributed long term capital gains had been distributed as "capital gain dividends" by us to our stockholders.

        Retention of Net Capital Gains.    We may elect to retain, rather than distribute as a capital gain dividend, all or a portion of our net capital gains. If we make this election, we would pay tax on our retained net capital gains. In addition, to the extent we so elect, our earnings and profits (determined for federal income tax purposes) would be adjusted accordingly, and a U.S. holder generally would:

        Passive Activity Losses and Investment Interest Limitations.    Distributions we make and gain arising from the sale or exchange by a U.S. holder of our capital stock will not be treated as passive activity income. As a result, U.S. holders generally will not be able to apply any "passive losses" against this income or gain. A U.S. holder may elect to treat capital gain dividends, capital gains from the disposition of our capital stock and income designated as qualified dividend income, as described in "—Tax Rates" below, as investment income for purposes of computing the investment interest limitation, but in such case, the holder will be taxed at ordinary income rates on such amount. Other distributions made by us, to the extent they do not constitute a return of capital, generally will be treated as investment income for purposes of computing the investment interest limitation.

        Dispositions of Our Capital Stock.    Except as described below under "Redemption or Repurchase by Us," if a U.S. holder sells or disposes of shares of our capital stock, it will recognize gain or loss for

58


Table of Contents

federal income tax purposes in an amount equal to the difference between the amount of cash and the fair market value of any property received on the sale or other disposition and the holder's adjusted basis in the shares of our capital stock for tax purposes. This gain or loss, except as provided below, will be long-term capital gain or loss if the holder has held such capital stock for more than one year. However, if a U.S. holder recognizes a loss upon the sale or other disposition of capital stock that it has held for six months or less, after applying certain holding period rules, the loss recognized will be treated as a long-term capital loss to the extent the U.S. holder received distributions from us which were required to be treated as long-term capital gains.

        Redemption or Repurchase by Us.    A redemption or repurchase of shares of our capital stock will be treated under Section 302 of the Code as a distribution (and taxable as a dividend to the extent of our current and accumulated earnings and profits as described above under "—Distributions Generally") unless the redemption or repurchase satisfies one of the tests set forth in Section 302(b) of the Code and is therefore treated as a sale or exchange of the redeemed or repurchased shares. The redemption or repurchase generally will be treated as a sale or exchange if it:

all within the meaning of Section 302(b) of the Code.

        In determining whether any of these tests has been met, shares of our capital stock, including common stock and other equity interests in us, considered to be owned by the U.S. holder by reason of certain constructive ownership rules set forth in the Code, as well as shares of our capital stock actually owned by the U.S. holder, must generally be taken into account. Because the determination as to whether any of the alternative tests of Section 302(b) of the Code will be satisfied with respect to the U.S. holder depends upon the facts and circumstances at the time that the determination must be made, U.S. holders are advised to consult their tax advisors to determine such tax treatment.

        If a redemption or repurchase of shares of our capital stock is treated as a distribution taxable as a dividend, the amount of the distribution will be measured by the amount of cash and the fair market value of any property received. See "—Distributions Generally." A U.S. holder's adjusted basis in the redeemed or repurchased shares of the stock for tax purposes generally will be transferred to its remaining shares of our capital stock, if any. If a U.S. holder owns no other shares of our capital stock, under certain circumstances, such basis may be transferred to a related person or it may be lost entirely. Proposed Treasury Regulations issued in 2009, if enacted in their current form, would affect the basis recovery rules described above. It is not clear whether these proposed regulations will be enacted in their current form or at all. Prospective investors should consult their tax advisors regarding the federal income tax consequences of a redemption or repurchase of our capital stock.

        If a redemption or repurchase of shares of our capital stock is not treated as a distribution taxable as a dividend, it will be treated as a taxable sale or exchange in the manner described under "—Dispositions of Our Capital Stock."

        Tax Rates.    The maximum tax rate for non-corporate taxpayers for (1) long-term capital gains, including certain "capital gain dividends," is generally 20% (although depending on the characteristics of the assets which produced these gains and on designations which we may make, certain capital gain dividends may be taxed at a 25% rate) and (2) "qualified dividend income" is generally 20%. In general, dividends payable by REITs are not eligible for the reduced tax rate on qualified dividend income, except to the extent that certain holding period requirements have been met and the REIT's dividends are attributable to dividends received from taxable corporations (such as its taxable REIT subsidiaries) or to income that was subject to tax at the corporate/REIT level (for example, if the

59


Table of Contents

REIT distributed taxable income that it retained and paid tax on in the prior taxable year). In addition, U.S. holders that are corporations may be required to treat up to 20% of some capital gain dividends as ordinary income.

Taxation of Tax-Exempt Holders of Our Capital Stock

        Dividend income from us and gain arising upon a sale of shares of our capital stock generally should not be unrelated business taxable income, or UBTI, to a tax-exempt holder, except as described below. This income or gain generally will be UBTI, however, if a tax-exempt holder holds its shares as "debt-financed property" within the meaning of the Code. Generally, "debt-financed property" is property the acquisition or holding of which was financed through a borrowing by the tax-exempt holder.

        For tax-exempt holders that are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, or qualified group legal services plans exempt from federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) or (c)(20) of the Code, respectively, income from an investment in our shares will constitute UBTI unless the organization is able to properly claim a deduction for amounts set aside or placed in reserve for specific purposes so as to offset the income generated by its investment in our shares. These prospective investors should consult their tax advisors concerning these "set aside" and reserve requirements.

        Notwithstanding the above, however, a portion of the dividends paid by a "pension-held REIT" may be treated as unrelated business taxable income as to certain trusts that hold more than 10%, by value, of the interests in the REIT. A REIT will not be a "pension-held REIT" if it is able to satisfy the "not closely held" requirement without relying on the "look-through" exception with respect to certain trusts or if such REIT is not "predominantly held" by "qualified trusts." As a result of restrictions on ownership and transfer of our stock contained in our charter, we do not expect to be classified as a "pension-held REIT," and as a result, the tax treatment described above should be inapplicable to our holders. However, because our stock is publicly traded, we cannot guarantee that this will always be the case.

Taxation of Non-U.S. Holders of Our Capital Stock

        The following discussion addresses the rules governing U.S. federal income taxation of the acquisition, ownership and disposition of our capital stock by non-U.S. holders. These rules are complex, and no attempt is made herein to provide more than a brief summary of such rules. Accordingly, the discussion does not address all aspects of U.S. federal income taxation and does not address state, local or non-U.S. tax consequences that may be relevant to a non-U.S. holder in light of its particular circumstances. We urge non-U.S. holders to consult their tax advisors to determine the impact of federal, state, local and non-U.S. income tax laws and any applicable tax treaty on the acquisition, ownership and disposition of shares of our capital stock, including any reporting requirements.

        Distributions Generally.    Distributions (including any taxable stock dividends) that are neither attributable to gains from sales or exchanges by us of United States real property interests, or USRPIs, nor designated by us as capital gain dividends (except as described below) will be treated as dividends of ordinary income to the extent that they are made out of our current or accumulated earnings and profits. Such distributions ordinarily will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, unless the distributions are treated as effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such dividends are attributable). Under certain treaties, however, lower withholding rates generally applicable to dividends do not apply

60


Table of Contents

to dividends from a REIT. Certain certification and disclosure requirements must be satisfied for a non-U.S. holder to be exempt from withholding under the effectively connected income exemption. Dividends that are treated as effectively connected with a U.S. trade or business generally will not be subject to withholding but will be subject to U.S. federal income tax on a net basis at the regular graduated rates, in the same manner as dividends paid to U.S. holders are subject to federal income tax. Any such dividends received by a non-U.S. holder that is a corporation may also be subject to an additional branch profits tax at a 30% rate (applicable after deducting U.S. federal income taxes paid on such effectively connected income) or such lower rate as may be specified by an applicable income tax treaty.

        Except as otherwise provided below, we expect to withhold U.S. federal income tax at the rate of 30% on any distributions made to a non-U.S. holder unless:

        Distributions in excess of our current and accumulated earnings and profits will not be taxable to a non-U.S. holder to the extent that such distributions do not exceed the adjusted basis of the holder's capital stock, but rather will reduce the adjusted basis of such stock. To the extent that such distributions exceed the non-U.S. holder's adjusted basis in such capital stock, they will give rise to gain from the sale or exchange of such stock, the tax treatment of which is described below. For withholding purposes, we expect to treat all distributions as made out of our current or accumulated earnings and profits. However, amounts withheld may be refundable if it is subsequently determined that the distribution was, in fact, in excess of our current and accumulated earnings and profits, provided that certain conditions are met.

        Capital Gain Dividends and Distributions Attributable to a Sale or Exchange of United States Real Property Interests.    Distributions to a non-U.S. holder that we properly designate as capital gain dividends, other than those arising from the disposition of a USRPI, generally should not be subject to U.S. federal income taxation, unless:

        Pursuant to the Foreign Investment in Real Property Tax Act, which is referred to as "FIRPTA," distributions to a non-U.S. holder that are attributable to gain from sales or exchanges by us of USRPIs, whether or not designated as capital gain dividends, will cause the non-U.S. holder to be treated as recognizing such gain as income effectively connected with a U.S. trade or business.

61


Table of Contents

Non-U.S. holders would generally be taxed at the regular graduated rates applicable to U.S. holders, subject to any applicable alternative minimum tax. We also will be required to withhold and to remit to the IRS 35% (or 20% to the extent provided in applicable Treasury Regulations) of any distribution to non-U.S. holders attributable to gain from sales or exchanges by us of USRPIs. Distributions subject to FIRPTA may also be subject to a 30% branch profits tax in the hands of a non-U.S. holder that is a corporation. The amount withheld is creditable against the non-U.S. holder's U.S. federal income tax liability. However, any distribution with respect to any class of stock that is "regularly traded" on an established securities market located in the United States is not subject to FIRPTA, and therefore, not subject to the 35% U.S. withholding tax described above, if the non-U.S. holder did not own more than 10% of such class of stock at any time during the one-year period ending on the date of the distribution. Instead, such distributions generally will be treated as ordinary dividend distributions and subject to withholding in the manner described above with respect to ordinary dividends. In addition, distributions to certain non-U.S. publicly traded shareholders that meet certain record-keeping and other requirements ("qualified shareholders") are exempt from FIRPTA, except to the extent owners of such qualified shareholders that are not also qualified shareholders own, actually or constructively, more than 10% of our capital stock. Furthermore, distributions to "qualified foreign pension funds" or entities all of the interests of which are held by "qualified foreign pension funds" are exempt from FIRPTA. Non-U.S. holders should consult their tax advisors regarding the application of these rules.

        Retention of Net Capital Gains.    Although the law is not clear on the matter, it appears that amounts we designate as retained net capital gains in respect of the capital stock held by U.S. holders generally should be treated with respect to non-U.S. holders in the same manner as actual distributions of capital gain dividends. Under this approach, the non-U.S. holders would be able to offset as a credit against their U.S. federal income tax liability their proportionate share of the tax paid by us on such retained net capital gains and to receive from the IRS a refund to the extent their proportionate share of such tax paid by us exceeds their actual U.S. federal income tax liability. If we were to designate any portion of our net capital gain as retained net capital gain, non-U.S. holders should consult their tax advisors regarding the taxation of such retained net capital gain.

        Sale of Our Capital Stock.    Except as described below under "—Redemption or Repurchase by Us," gain realized by a non-U.S. holder upon the sale, exchange or other taxable disposition of our capital stock generally will not be subject to U.S. federal income tax unless such stock constitutes a USRPI. In general, stock of a domestic corporation that constitutes a "U.S. real property holding corporation," or USRPHC, will constitute a USRPI. We believe that we are a USRPHC. Our capital stock will not, however, constitute a USRPI so long as we are a "domestically controlled qualified investment entity." A "domestically controlled qualified investment entity" includes a REIT in which at all times during a specified testing period less than 50% in value of its stock is held directly or indirectly by non-U.S. persons, subject to certain rules. For purposes of determining whether a REIT is a "domestically controlled qualified investment entity," a person who at all applicable times holds less than 5 percent of a class of stock that is "regularly traded" is treated as a U.S. person unless the REIT has actual knowledge that such person is not a U.S. person. We believe, but cannot guarantee, that we are a "domestically controlled qualified investment entity." Because our stock is (and, we anticipate, will continue to be) publicly traded, no assurance can be given that we will continue to be a "domestically controlled qualified investment entity."

        Even if we do not qualify as a "domestically controlled qualified investment entity" at the time a non-U.S. holder sells our capital stock, gain realized from the sale or other taxable disposition by a non-U.S. holder of such capital stock would not be subject to U.S. federal income tax under FIRPTA as a sale of a USRPI if:

62


Table of Contents

        In addition, dispositions of our capital stock by qualified shareholders are exempt from FIRPTA, except to the extent owners of such qualified shareholders that are not also qualified shareholders own, actually or constructively, more than 10% of our capital stock. An actual or deemed disposition of our capital stock by such shareholders may also be treated as a dividend. Furthermore, dispositions of our capital stock by "qualified foreign pension funds" or entities all of the interests of which are held by "qualified foreign pension funds" are exempt from FIRPTA. Non-U.S. holders should consult their tax advisors regarding the application of these rules.

        Notwithstanding the foregoing, gain from the sale, exchange or other taxable disposition of our capital stock not otherwise subject to FIRPTA will be taxable to a non-U.S. holder if either (a) the investment in our capital stock is treated as effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable), in which case the non-U.S. holder will be subject to the same treatment as U.S. holders with respect to such gain, except that a non-U.S. holder that is a foreign corporation may also be subject to the 30% branch profits tax (or such lower rate as may be specified by an applicable income tax treaty) on such gain, as adjusted for certain items, or (b) the non-U.S. holder is a nonresident alien individual who is present in the United States for 183 days or more during the taxable year and certain other conditions are met, in which case the non-U.S. holder will be subject to a 30% tax on the non-U.S. holder's capital gains (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the non-U.S. holder (even though the individual is not considered a resident of the United States), provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses. In addition, even if we are a domestically controlled qualified investment entity, upon disposition of our capital stock, a non-U.S. holder may be treated as having gain from the sale or other taxable disposition of a USRPI if the non-U.S. holder (1) disposes of our capital stock within a 30-day period preceding the ex-dividend date of a distribution, any portion of which, but for the disposition, would have been treated as gain from the sale or exchange of a USRPI and (2) acquires, or enters into a contract or option to acquire, or is deemed to acquire, other shares of that stock during the 61-day period beginning with the first day of the 30-day period described in clause (1), unless such stock is "regularly traded" and the non-U.S. holder did not own more than 5% of the stock at any time during the one-year period ending on the date of the distribution described in clause (1).

        If gain on the sale, exchange or other taxable disposition of our capital stock were subject to taxation under FIRPTA, the non-U.S. holder would be required to file a U.S. federal income tax return and would be subject to regular U.S. federal income tax with respect to such gain in the same manner as a taxable U.S. holder (subject to any applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals). In addition, if the sale, exchange or other taxable disposition of our capital stock were subject to taxation under FIRPTA, and if shares of the applicable class of our capital stock were not "regularly traded" on an established securities market, the purchaser of such capital stock generally would be required to withhold and remit to the IRS 10% (15% for dispositions occurring after February 16, 2016) of the purchase price.

        Redemption or Repurchase by Us.    A redemption or repurchase of shares of our capital stock will be treated under Section 302 of the Code as a distribution (and taxable as a dividend to the extent of our current and accumulated earnings and profits) unless the redemption or repurchase satisfies one of the tests set forth in Section 302(b) of the Code and is therefore treated as a sale or exchange of the redeemed or repurchased shares. See "—Taxation of Taxable U.S. Holders of Our Capital Stock—Redemption or Repurchase by Us." If the redemption or repurchase of shares is treated as a

63


Table of Contents

distribution, the amount of the distribution will be measured by the amount of cash and the fair market value of any property received. See "—Taxation of Non-U.S. Holders of Our Capital Stock—Distributions Generally." If the redemption or repurchase of shares is not treated as a distribution, it will be treated as a taxable sale or exchange in the manner described under "—Taxation of Non-U.S. Holders of Our Capital Stock—Sale of Our Capital Stock."

Taxation of Holders of Our Debt Securities

        The following summary describes the material U.S. federal income tax consequences of acquiring, owning and disposing of our debt securities. This discussion assumes the debt securities will be issued with less than a statutory de minimis amount of original issue discount for U.S. federal income tax purposes. In addition, this discussion is limited to persons purchasing the debt securities for cash at original issue and at their original "issue price" within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial amount of the debt securities is sold to the public for cash).

        Payments of Interest.    Interest on a debt security generally will be taxable to a U.S. holder as ordinary income at the time such interest is received or accrued, in accordance with such U.S. holder's method of accounting for U.S. federal income tax purposes.

        Sale or Other Taxable Disposition.    A U.S. holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a debt security. The amount of such gain or loss generally will be equal to the difference between the amount received for the debt security in cash or other property valued at fair market value (less amounts attributable to any accrued but unpaid interest, which will be taxable as interest to the extent not previously included in income) and the U.S. holder's adjusted tax basis in the debt security. A U.S. holder's adjusted tax basis in a debt security generally will be equal to the amount the U.S. holder paid for the debt security. Any gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if the U.S. holder has held the debt security for more than one year at the time of such sale or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, generally will be taxable at reduced rates. The deductibility of capital losses is subject to limitations.

        Payments of Interest.    Interest paid on a debt security to a non-U.S. holder that is not effectively connected with the non-U.S. holder's conduct of a trade or business within the United States generally will not be subject to U.S. federal income tax or withholding, provided that:

64


Table of Contents

        If a non-U.S. holder does not satisfy the requirements above, such non-U.S. holder will be subject to withholding tax of 30%, subject to a reduction in or an exemption from withholding on such interest as a result of an applicable tax treaty. To claim such entitlement, the non-U.S. holder must provide the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming a reduction in or exemption from withholding tax under the benefit of an income tax treaty between the United States and the country in which the non-U.S. holder resides or is established.

        If interest paid to a non-U.S. holder is effectively connected with the non-U.S. holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such interest is attributable), the non-U.S. holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the non-U.S. holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that interest paid on a debt security is not subject to withholding tax because it is effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States.

        Any such effectively connected interest generally will be subject to U.S. federal income tax at the regular graduated rates. A non-U.S. holder that is a corporation may also be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected interest, as adjusted for certain items.

        The certifications described above must be provided to the applicable withholding agent prior to the payment of interest and must be updated periodically. Non-U.S. holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

        Sale or Other Taxable Disposition.    A non-U.S. holder will not be subject to U.S. federal income tax on any gain realized upon the sale, exchange, redemption, retirement or other taxable disposition of a debt security (such amount excludes any amount allocable to accrued and unpaid interest, which generally will be treated as interest and may be subject to the rules discussed above in "—Taxation of Holders of Our Debt Securities—Non-U.S. Holders—Payments of Interest") unless:

        Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A non-U.S. holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

        Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the non-U.S. holder (even though the individual is not considered a resident of the United States), provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

65


Table of Contents

        Non-U.S. holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

        U.S. Holders.    A U.S. holder may be subject to information reporting and backup withholding when such holder receives payments on our capital stock or debt securities or proceeds from the sale or other taxable disposition of such stock or debt securities (including a redemption or retirement of a debt security). Certain U.S. holders are exempt from backup withholding, including corporations and certain tax-exempt organizations. A U.S. holder will be subject to backup withholding if such holder is not otherwise exempt and such holder:

        Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

        Non-U.S. Holders.    Payments of dividends on our capital stock or interest on our debt securities generally will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our capital stock or interest on our debt securities paid to the non-U.S. holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of such stock or debt securities (including a retirement or redemption of a debt security) within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a U.S. person, or the holder otherwise establishes an exemption. Proceeds of a disposition of such stock or debt securities conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

        Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides or is established.

        Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Medicare Contribution Tax on Unearned Income

        Certain U.S. holders that are individuals, estates or trusts are required to pay an additional 3.8% tax on, among other things, dividends on stock, interest on debt obligations, and capital gains from the sale or other disposition of stock or debt obligations. U.S. holders should consult their tax advisors regarding the effect, if any, of these rules on their ownership and disposition of our capital stock or debt securities.

Additional Withholding Tax on Payments Made to Foreign Accounts

        Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such sections commonly referred to as the Foreign Account Tax Compliance Act, or FATCA) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on our capital stock, interest on our debt securities, or gross proceeds from the sale or other disposition of our capital stock or debt securities, in each case paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any "substantial United States owners" (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (1) above, it must enter into an agreement with the U.S. Department of the Treasury under which it undertakes, among other things, to identify accounts held by certain "specified United States persons" or "United States-owned foreign entities" (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

        Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our capital stock or interest on our debt securities, and will apply to payments of gross proceeds from the sale or other disposition of such stock or debt securities on or after January 1, 2019.

        Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our capital stock or debt securities.

Other Tax Consequences

        State, local and non-U.S. income tax laws may differ substantially from the corresponding federal income tax laws, and this discussion does not purport to describe any aspect of the tax laws of any state, local or non-U.S. jurisdiction, or any federal tax other than the income tax. You should consult your tax advisor regarding the effect of state, local and non-U.S. tax laws with respect to our tax treatment as a REIT and on an investment in our capital stock or debt securities.

The underwriters may resell the securities in one or more transactions, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to prevailing market prices or at negotiated prices.

        The securities may be offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase the securities will be subject to certain conditions.

        We may sell securities through agents designated by us. Any agent involved in the offer or sale of the securities pursuant to this prospectus will be named, and any commissions payable by us to that agent will be set forth, in the prospectus supplement or other offering materials.

        Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act, and any discounts or commissions received by them from us and any profit on the resale of the securities by them may be treated as underwriting discounts and commissions under the Securities Act.

        We may have agreements with the underwriters, dealers and agents to indemnify them against certain liabilities, including liabilities under the Securities Act or to contribute with respect to payments which the underwriters, dealers or agents may be required to make. Additionally, underwriters, dealers and agents and their affiliates may engage in transactions with, or perform services for, us or our subsidiaries in the ordinary course of their businesses.

        In order to facilitate the offering of our securities, any underwriters or agents, as the case may be, involved in the offering of such securities may engage in transactions that stabilize, maintain or otherwise affect the price of such securities or other securities. Specifically, the underwriters or agents,

as the case may be, may overallot in connection with the offering, creating a short position in such securities for their own account. In addition, to cover overallotments or to stabilize the price of the securities or of such other securities, the underwriters or agents, as the case may be, may bid for, and purchase, such securities in the open market. Finally, in any offering of such securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing such securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters or agents, as the case may be, are not required to engage in these activities, and may end any of these activities at any time without notice.

        We also may solicit offers to purchase securities directly from, and we may sell securities directly to, institutional investors or others. The terms of any of those sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement or other offering materials.

        Some or all of the securities we may sell may be new issues of securities with no established trading market. We cannot give any assurances as to the liquidity of the trading market for any of our securities.
